Background Art

In the past, the known discharge having sterilization function the function of electrolytic water and water of the water tap device. For example, in Patent document 1 discloses a technique in which, in the discharge of the electrolytic water in the kitchen, in order to prevent the washing device in the corrosion of the metal part, so that the electrolytic water concentration in the predetermined range.

Patent document 1: Japanese extra flat 11 - 235378 Bulletin

However, according to the above Patent document 1 is recorded in the technology, the use of the concentration of the electrolytic water is limited in the scope of the corrosion of the metal part. Therefore, for example due to the concentration of the electrolytic water is suppressed relatively low, therefore the presence of the electrolytic water sterilizing function of not effectively play.

Therefore, the invention solves the technical problem is, in the ejection electrolytic water such as tap water in the function of the device, does not depend on the concentration of the functional water can be properly inhibit the passage of the function such as corrosion.

Content of the invention

In order to achieve the above-mentioned purpose, the present invention provides a tap device, having: function generating part, through the work after being energized, the water in the reforming to produce the functional water; the water-functional water spit, spit out by the function of the functional water generating part for generating a; function passage, flow functional water, from the functional water generating part extends to the functional water spit-back by the water; and a control section, the function generating unit controls, characterized in that the control section performs the following control, in the passage by the function of the functional water spit-back and a water discharge section 1 concentration after the functional water, to supply lower than the passage of the function 1 concentration of article 2 concentration of functional water.

In the thus constituted in the present invention, because the passage through the function of the functional water spit-back by the water discharge section 1 concentration after the functional water, to supply lower than the passage of the function 1 concentration of article 2 concentration of functional water, so can dilute the function passage in the concentration of the functional water. By this, can be unlike the above-mentioned Patent document 1 as recorded in the technology, is not limited to the use of the functional water concentration, also can inhibit the function of the passage in the function in the function such as caused by the passage is corrosion (deterioration). Therefore, according to the present invention, the function is not taken into consideration such as corrosion of the passage, can use various concentration of functional water.

In the present invention, the preferred function generating section through the is energized so that the reforming water through electrolysis, success can generate water, the control unit through the control function of the energization of the aquatic in code power, so that the functional water spit-back and a water discharge section 1 concentration after the functional water, supply passage to the function of the 2 concentration of functional water.

In the thus constituted in the present invention, the aquatic in code by the energization of the the function of power reduced as a function of the concentration of the water from 1 concentration to the article 2 concentration are reduced, it is not necessary in order to produce the article 2 concentration function of the other flow path for water (specifically, without from the other flow path supply the ordinary water and the like to make the function of reducing the water concentration). Therefore, a device can be simplified.

In the present invention, preferably the control portion by passing a predetermined electric power function generating part, so that the functional water spit-back and a water discharge section 1 the function of the concentration of the water, and aquatic in code by the energization of the power function is 0, the energization of the aquatic stop function in code, thus to supply the function of passage 2 concentration is 0 or non-functional water generating part reforming of ordinary water.

In the thus constituted in the present invention, by making the function of the energization of the aquatic in code power is 0, the energization of the aquatic stop function in code, so as to serve as article 2 concentration of functional water is supplied to the function of the ordinary water passage, so can effectively dilution function in the function of the passage of the water concentration, can be effective to inhibit the function of passage such as corrosion.

In the present invention, preferably also with electromagnetic valve, through closing the ordinary water to supply and cut off the passage of the function of the switch, the control portion of the electromagnetic valve to control, in the power generating part to the function, the function of the functional water passage through the water-discharge of the spit 1 concentration after the functional water, the energization of the aquatic in code function is stopped, to stop the supply of the function passage 1 concentration of functional water, at the same time the function of the supply passage to the ordinary water.

In the thus constituted in the present invention, because of the electromagnetic valve to control, via the function passage in the functional water spit-back by the water after the water out function, stop function of the energization of the aquatic in code, at the same time the function of the ordinary water supply to passage, so that through the passage to the function of the ordinary water supply to replace the functional water, and by the common water discharge function in the passage of the functional water thus for ordinary water replacement is to be performed, can be appropriately diluted function in the passage of the function of the concentration of water (it supply the mixture is common when the water, can be the function passage in the functional water almost fully discharged, thus the common function is filled with water in the passage). By this, can be effective to inhibit the function of passage such as corrosion.

In the present invention, preferably electromagnetic valve is arranged in the upstream side of the aquatic in code function, through the closing by the function to the aquatic in code of the ordinary water to supply and cut off the passage of the function of the switch, the control portion makes the valve opening of the electromagnetic valve, while at the same time to the functional water generating part is energized, by the function of the functional water passage and a water discharge of the spit 1 concentration of functional water, since then, the energization of the aquatic stop function in code, at the same time the solenoid valve opening state to keep the specified time, to function so as to stop supply of the passage 1 concentration of functional water, the ordinary water supply passage to the function.

In the thus constituted in the present invention, because of the use of the function generating portion arranged on the upstream side of the solenoid valve to the aquatic in code via the function of the ordinary water to supply and cut off the passage of the function of the switch, it is not necessary to the function used in the ordinary water supply passage of the other flow path. Therefore, a device can be simplified.

In the present invention, preferably the control portion in the stop function after the energization of the aquatic in code, to function with the function of the passage volume of the supply passage to a small amount compared with the more common water.

In the thus constituted in the present invention, in the supply passage to the function with the function of the passage volume phase infer more common under the water condition, because the functional water discharge after ejection for the ordinary water, so the use of ordinary water flushing to the hand washer of the spat functional water basins and the like, can inhibit the functional water to the basin or the impact of the sieve plate and the like.

According to the present invention, can be in the discharge electrolytic water such as in the functional water tap device, does not depend on the concentration of the functional water can be properly inhibit the passage of the function such as corrosion.

Figure 2 (A) is observed from an oblique lower part of the embodiment of the present invention automatic water tap device three-dimensional view, Figure 2 (B) is along the Figure 2 (A) in the IIB - IIB-line observation of the automatic water tap device of cutaway view. In this, mainly to this embodiment in the automatic water tap device 1 in the vicinity of the spits shui bu composition of the note.

As shown in Figure 2 (A) shown, automatic water tap device 1 has a curved tubular member that the discharge pipe 11. As shown in Figure 2 (A) and Figure 2 (B) shown, the spit-back pipe 11 of this shaft is provided with the top end of the: section 1 spit-back by the water 12, from the section 1 spit-back nozzle 12 a in the form of a bubble guttation of; of large section 2 spit-back by the water 13, in order to from section 2 spit-back outlet 13 a spray guttation (in other words as the fog-like guttation) is embodied in the form of; sensor 14, such as the use of the infrared ray to detect detected objects; and irradiation light of the LED (light emitting diode) 15. Specifically, in the discharge pipe 11 of the tip portion, the above-mentioned part downward in order to sensor 14, article 1 spit-back nozzle 12 a, LED15, article 2 spit-back outlet 13 a is assigned to the order. And, in the discharge pipe 11 is also provided with the interior of the: section 1 the flow path 17, with the article 1 spit-back by the water 12 is connected, to the section 1 by the water out of the 12 water supply; and section 2 flow path 18, with the section 2 and a water discharge 13 connected, to the section 2 by the water out of the 13 water supply (also including the last-mentioned electrolytic water). In addition, article 2 spit-back by the water 13 in this invention is equivalent to the "functional water spit-back by the water", article 2 flow path 18 in this invention is equivalent to the "function flow path".

In this, as the bubble guttation, article 1 spit-back by the water 12 in the following bubble guttation, namely of the filter by the mixture of air, so that the spat containing bubbles in the water flow. The article 1 spit-back by the water 12 of bubble guttation equivalent to the invention in the "article 1 guttation mode". On the other hand, as the spray guttation, article 2 spit-back by the water 13 in the following of the fog guttation, namely the water from section 2 spit-back outlet 13 a to provide angle spread the kind of mist guttation, in other words, is water-diffusion to the than the 2 out of the outlet 13 a of the cross-sectional area (diameter) greater range of that kind of mist guttation. The article 2 spit-back by the water 13 spray guttation equivalent to the invention in the "article 2 guttation mode". Moreover, article 2 spit-back by the water 13 in less than section 1 spit-back by the water 12 the flow rate of the spray guttation, while at the same time higher than the 1 spit-back by the water 12 of the velocity of spray guttation. As an example, section 1 by the water out of the 12 water per minute to 2 liter bubble guttation, article 2 by the water out of the 13 water per minute for 0.3 liter spray guttation.

Below, with reference to Figure 3, the section of this embodiment 2 spit-back by the water 13 spray guttation the principle of note. Figure 3 is the longitudinal cutaway view of along the flowing direction of water observation section 2 spit-back by the water 13.

As shown in Figure 5, in this embodiment, article 2 spit-back by the water 13 of section 2 spit-back outlet 13 a set in the than the 1 spit-back by the water 12 of article 1 out of the outlet 12 a to the rear of the rear-side, in order to make the from clause 1 spit-back nozzle 12 a drop of water will not drip onto the article 2 spit-back outlet 13 a on. At this moment, article 2 spit-back by the water 13 of section 2 spit-back outlet 13 a also is disposed from the article 2 spit-back outlet 13 a spray discharge of the water will not spill on to the article 1 spit-back by the water 12 of article 1 spit-back nozzle 12 a on. In addition, article 2 spit-back by the water 13 of section 2 spit-back outlet 13 a is disposed toward the basin 3 near the outlet of the (Figure 5 in not shown) spray guttation. Moreover, in this embodiment, sensor 14 set in the than the 2 spit-back by the water 13 of section 2 spit-back outlet 13 a is in front of the front side, in order to people even if not so handle extends to the side of the pocket to be suitably is sensor 14 detecting the hand. In other words, article 2 spit-back outlet 13 a set in the ratio sensor 14 rearward of the rear-side. By this arrangement, from section 2 spit-back outlet 13 a spray discharge of water to the user's arm, body and other do not hope to be wetted part.

In addition, in this embodiment, sensor 14 with the section 2 and a water discharge 13 adopts the following towards the relations, namely sensor 14 detecting less than from section 2 spit-back by the water 13 of section 2 spit-back outlet 13 a spray discharge of water. Specifically, because the from the sensor 14 and farther the sensor 14 and the detection precision of the more reduced, the sensor 14 with the section 2 and a water discharge 13 adopts the following towards the relations, i.e. corresponding to the detected direction A23 pointing range R13 (is includes a sensor 14 of the detection range of range, detailed and the speech is equivalent to the detection range of the extension of the range to the front) with article 2 spit-back by the water 13 of the guttation range R11 in the far away from the position of the front side of the intersecting, the detection direction of the A23 is with the sensor 14 detecting the detected object related direction. For the purposes of in detail, sensor 14 is disposed in the following way, sensor 14 of the detection direction of the A23 towards gradually leave the article 2 spit-back by the water 13 of the guttation direction A22 direction. In other words, the sensor 14 is disposed in the following way, along the sensor 14 of the detection direction of the A23 straight line L13 (typically is equivalent to the sensor 14 of the central axis) in the front side and from section 2 spit-back by the water 13 of section 2 spit-back outlet 13 a in the vertical direction in the center of a straight line extending on the L12 (typically is equivalent to section 2 spit-back by the water 13 of the central axis) does not intersect.

In addition, in this embodiment, article 1 spit-back by the water 12 and 2 spit-back by the water 13 adopts the following towards the relations, from section 2 spit-back by the water 13 of section 2 spit-back outlet 13 a spray discharge of the user's water is difficult. Specifically, article 1 spit-back by the water 12 and section 2 by the water out of the 13 are disposed in such a manner that, article 1 spit-back by the water 12 of guttation direction A21 and 2 spit-back by the water 13 of the guttation direction A22 towards the direction of gradually away from each other. In other words, article 1 spit-back by the water 12 and section 2 by the water out of the 13 are disposed in such a manner that, from section 1 spit-back by the water 12 of article 1 spit-back nozzle 12 a in the vertical direction in the center of a straight line extending on the L11 (typically is equivalent to section 1 spit-back by the water 12 of the central axis) in the front side and from section 2 spit-back by the water 13 of section 2 spit-back outlet 13 a in the vertical direction in the center of a straight line extending on the L12 (typically is equivalent to section 2 spit-back by the water 13 of the central axis) does not intersect.

Below, with reference to Figure 6, to the embodiment of the invention automatic water tap device a description of the functions that form. Figure 6 is the block diagram of illustrative represent the embodiment of the present invention functions that form the automatic water tap device.

As shown in Figure 6, of this embodiment automatic water tap device 1 in the above-mentioned article 1 flow path 17 and section 2 flow path 18 (with reference to Figure 2 and the like) connected with both the upstream side of the altogether throughflow road 21. In the altogether throughflow road 21 supplied in common tap water (city water supply) and the ordinary water (in the specification in order to the water different from the electrolytic water and appropriate expressed as "common water"). In altogether throughflow road 21 on, from the upstream side to the is provided with a: stop bolt 22, used for cutting off altogether throughflow road 21 in the ordinary water circulation; filter 23, mixed into the ordinary water in removing foreign body; and constant flow rate valve 24, the flow rate of the secondary side to maintain a certain, in altogether throughflow road 21 the downstream end of the, article 1 flow path 17 with the article 2 flow path 18 branch.

In the paragraph 1 flow path 17 in, provided with article 1 solenoid valve 25, through the closing of the 1 flow path 17 in the ordinary water circulation and cut-off switch. The article 1 solenoid valve 25 when the valve, ordinary water at the 1 flow path 17 flow, from section 1 flow path 17 is connected to the downstream end of the section 1 spit-back by the water 12, common water is the bubble guttation.

On the other hand, at the 2 flow path 18 in, from the upstream side to be provided with the 2 solenoid valve 28, pressure regulating valve 29, safety valve 30, check valve 35 and the electrolytic bath 37. Rule 2 solenoid valve 28 through closing the articles 2 flow path 18 in the common water circulation and cut-off switch. The article 2 solenoid valve 28 when the valve is, the ordinary water in section 2 flow path 18 flow, from section 2 flow path 18 connected to the downstream end of the section 2 and a water discharge 13 spray guttation. The pressure regulating valve 29 is the water pressure is adjusted to the pressure required (suitable for spray guttation pressure) of the valve. Safety valve 30 is in part 2 flow path 18 change the pressure in more than a predetermined pressure (for example section 2 spit-back outlet 13 a is blocked rule 2 flow path 18 of the pressure rises sharply) the valve, so that the rule 2 flow path 18 in the water medium by communicating with 31 flows to the article 1 flow path 17, so that the rule 2 flow path 18 of the pressure relief valve. Check valve 35 is to prevent the water in countercurrent valve. The electrolytic cell 37 through ordinary after being energized for electrolyzing the water, generating electrolytic water (the electrolytic cell 37 is equivalent to the invention in the "function aquatic cheng bu"). In addition, can also be of the electrolytic tank 37 is also arranged in the downstream side of the filter.

In addition, automatic water tap device 1 also has the automatic water tap device 1 in forming part of the control of the controller 40 (the controller 40 is equivalent to the invention in the "control unit"). Controller 40 from the AC power supply through the 39 of the work of the power but, at the same time respectively to the sensor 14, LED15, article 1 solenoid valve 25, article 2 solenoid valve 28 and electrolytic cell 37 supply AC power supply 39 of the power control. Specifically, controller 40 is shown the sensor 14 to be detected is the state of the detection signal of the sensor, and the sensor signal according to the following control, the switching LED15 opening/closing control, switching section 1 solenoid valve 25 of the opening and closing of the, switching section 2 solenoid valve 28 and of the opening and closing of the switching cell 37 generate electrolyzed water/stop of the implementation of the control.

In this, by the electrolytic cell 37 generating electrolytic water by way of illustration.

As in this embodiment electrolytic water, so long as it is obtained through the electrolysis of water sterilizing function is anything can be. As a representative of the electrolytic water, may be mentioned the electrolytic water containing hypochlorous acid. Because usually in water or in the water containing chlorine, so by electrolyzing produce free chlorine. The free chlorine in the acid is taken as the hypochlorous acid (HClO) in the presence of the, in this under the shape, than microbial powders as the alkaline lower of the existing form of hypochlorite ion (ClO^- ) About strong 10 times. And, even if it is a neutral can also receive the intermediate degree of strong kills to render. Therefore, in the continuous electrolytic water electrolysis with strong microbial powders become of sterilizing water.

As mentioned above, usually use water or water may contain chloride ion, but in chloride ion concentration low areas when in use or when the strong bactericidal action, by adding the salt and the like chloride can supplement the chloride ion.

As against high and the use of the electrode, the use of conductive substrate has the chlorine contained in the catalyst for producing the conductive material or by chlorine for producing the formed of conductive material to the catalyst. According to chlorine for producing the type of catalyst, such as the existence of ferrite and iron electrode, arrowhead department electrode, ruthenium electrode, electrode, platinum electrode, ruthenium - tin series electrode, palladium - platinum electrode, iridium - platinum electrode, platinum electrode ruthenium -, iridium - - tantalum department electrode such as platinum. Because of the conductivity in the substrate has the chlorine contained in the catalyst for producing the conductive material can be used for low-cost titanium, stainless steel and other materials to form the shoulder structure of the substrate Department, so the cost of manufacture is very favorable.

In addition to the outside chlorine, also can be through the electrolytic containing halogen ion of the acid and water is obtained.

As the other electrolytic water, can be cited as the electrode is obtained by the use of silver of the silver ionized water. Because the silver ion suction for the enzyme on a cell membrane of the bacteria, the role of the hindrance enzyme, is therefore considered to bacteria which can not sustain life. Also with the contact surface of the substrate to the role of the coating, the surface of the bacteria in the substrate become difficult to propagation. Because the silver ions to the substrate surface coating can prevent bacterial attachment to, and to render it has kills, so can effectively inhibit the propagation of bacteria in the surface of the substrate. At this moment, by cooperating with the increasing the drainage pipe of the transparency of the cleaning method, can be long-term suppression of the water outlet of the stick-slipping or odor.

In addition, also can be suitable for the use of a variety of electrolytic water, in particular through the electrolytic electrode for use as lead dioxide (β-type) in the anode side of oxygen at the same time also to produce high concentration ozone such as ozonated water.

In addition, as electrolytic water other than the ozone, can enumerate various antibacterial components dissolved aqueous solution. As the dissolution of the antibacterial components, the use of a solid, liquid, gas in any one of the can. When using the liquid antibacterial components, such as the use of ethanol, isopropanol alcohol, or hydrogen peroxide and the like can be. In addition, the use of gas to sterilize the components, for example through the ozone as fine bubbles to be dissolved in water to make the ozone water can be. In addition, when using solid antibacterial components, such as the use of sodium hypochlorite such as can be.

As mentioned above various sterilizing water in this invention is equivalent to the "functional water". Here, in the specification, the term "sterilize" is not only reducing bacterial mean (at this moment is not only to remove the bacteria but reduce the mean, also includes sterilizing and reduce the mean), also includes the even does not reduce the bacteria also inhibit the propagation of the bacteria mean, is used as a generalized concept. In the invention of the "functional water" mean that the above meaning of the sterilizing function through the established the additional in ordinary water in the water.

In addition, in this embodiment, as a function of this invention is water, although a list of examples of the use of electrolytic water note, but instead of the electrolytic water can also be used in addition to the electrolytic water other than the above-described eliminates the fungus water, it is also self-evident.

In addition, article 2 solenoid valve 28 of the driving signal is equivalent to section 2 solenoid valve 28 and closing state, article 1 solenoid valve 25 of the driving signal is equivalent to section 1 solenoid valve 25 for opening and closing state, the electrolytic cell 37 of the driving signal is equivalent to electrolytic cell 37 of the open/close state (in other words the electrolytic bath 37 work/non-state), LED15 LED15 driving signal corresponding to the opening/closing state.

First of all, at the time t11, sensor signal by the concern trades is open, that is to say the sensor 14 by the non-detection state is switched to the detection state. At this time, controller 40 to article 1 solenoid valve 25 is energized, so that the article 1 solenoid valve 25 opening, so that the article 1 spit-back by the water 12 perform the ordinary water bubble guttation. The bubble guttation is used for the user of the toilet and the like guttation. The following, in such a for the purposes guttation appropriate known as "for washing hands guttation" (in addition, the spit-back the purpose of water is not only washing, is also used for face washing, or the basin 3 in water storage, or cleaning brush and the like for a variety of purposes, but in order to facilitate different from the last-mentioned follow-up guttation, to toilet represented the use of "for washing hands guttation" a word). Then, at the time t12, sensor signal by switching a wire opening, that is to say the sensor 14 by the detection state switching is a non-detection state. At this time, the controller 40 to stop the article 1 solenoid valve 25 is energized, so that the article 1 solenoid valve 25 closing valve, from the end of the paragraph 1 spit-back by the water 12 the bubble guttation, that is to say the end of the for washing hands guttation.

Thereafter, as from the end of the toilet for water discharge of the moment bubble guttation after t12 start, when the sensor 14 of the non-detection state continue for a prescribed time T1 when, controller 40 make the article 2 spit-back by the water 13 spray guttation. The spray guttation is in order to prevent the use of the wash water discharge for hand washing out of the dirt to adhere to the hand washer 5 of the basin 3 and the state of the drying, and thus become difficult to remove the adhered to the of the (following in such a for the purposes guttation as hand washing water discharge imposed after the guttation appropriate known as the "follow-up guttation"). In other words, from the toilets for guttation starting from the end of stipulated time T1 after, as a follow-up guttation spray guttation, in order to produce guttation for washing hands dirt drying, before the dirt adhered to the wash. According to the above-mentioned viewpoint, the predetermined time T1 is generated according to the toilets for dirt and achieves the effect of guttation, until the time of the inner set. For example, predetermined time T1 is set to 3 seconds.

Specifically, the controller 40 first at the time t13 to the LED15 is open, the LED15 for light to the article 2 spit-back by the water 13 spray guttation of guttation range R11 irradiating (with reference to Figure 4), the notification to the user thereafter spraying will occur guttation. Then, controller 40 in the following time t13 moment t14 (from the end of the for washing hands guttation moment t12 begin to pass a predetermined time T1 after the time of the relative should be), to the section 2 the electromagnetic valve 28 is energized, so that the rule 2 solenoid valve 28 opening, and in the moment immediately t14 moment t15 the electrolytic tank 37 energized, through the electrolytic cell 37 generating electrolytic water, so that the electrolytic water from section 2 spit-back by the water 13 spray guttation, that is to say follow-up guttation. So, it is not the simultaneously in paragraph 2 solenoid 28 energized and the electrolytic bath 37 of the electrifying, but in article 2 solenoid valve 28 commence until after the start of current to the electrolytic cell 37 energized, this is because in paragraph 2 solenoid valve 28 is opened by the opening and closing switching time to consume a large amount of power, therefore it is not in the switching time to the electrolytic cell in the 37 energized, but during the power stability of the electrolytic tank 37 energized.

Thereafter, in the from clause 2 solenoid valve 28 the moment of opening the valve t14 begin to pass a predetermined time T3 (for example 1.9 seconds) time t16, controller 40 to stop the electrolytic tank 37 is energized, the end of the electrolytic cell 37 to generate electrolytic water. At this time, as a result of the 2 solenoid valve 28 is still open valve, therefore from section 2 spit-back by the water 13 to continue spraying guttation. Then, at the time t16 after the moment of the t17, specifically in the from clause 2 solenoid valve 28 the moment of opening the valve t14 begin to pass a predetermined time T2 (for example 3.5 seconds) time t17, controller 40 of the LED15 a wire, from the end of the LED15 irradiating light, at the same time stop to the article 2 solenoid valve 28 is energized, so that the rule 2 solenoid valve 28 closing valve, so the end of the rule 2 spit-back by the water 13 spray guttation, that is to say the end of the follow-up guttation.

In this, in order to lengthen the electrolytic cell 37 and the service life of (durable years), preferably on the control of the above-mentioned follow-up guttation.

As an example, controller 40 is not in every time when washing hands for guttation follow-up guttation, but in a predetermined number of times each for washing hands guttation when the follow-up guttation. Specifically, the controller 40 for washing hands guttation implementation to counting the number of, in the counted number is not reached during a prescribed number of times of the follow-up guttation, in the counted number of times reaches the prescribed number of times when the follow-up guttation, removal of the counting the number of times the at this time, the wash water discharge for the implementation of counting down the number again. In this case, the controller 40 when the follow-up guttation electrolytic water.

As another example, controller 40 although in each time when the guttation for washing hands follow-up guttation, but properly switching the use of the electrolytic water of the follow-up guttation and not using the electrolytic water follow-up guttation (that is to say the use of ordinary water follow-up guttation). At this time, controller 40 performs a predetermined number of times each of the follow-up guttation used an electrolytic water. Specifically, the controller 40 to the follow-up guttation implementation that counts the number of, in the counted number is not reached during a prescribed number of times of the electrolytic tank 37 energized, thus the use of the ordinary water follow-up guttation, in the counted number of times reaches the prescribed number of times to the electrolytic cell when the 37 energized, thus the use of the electrolytic water follow-up guttation, counting the number of times the time for removal of the, the number of times of the follow-up guttation implementation of counting down once again.

As the other another example, controller 40 although in each time when the guttation for washing hands follow-up guttation, but change the electrolytic tank 37 by the time of the follow-up guttation. That is to say, controller 40 in the follow-up guttation changed when used by the concentration of the electrolytic water. Specifically, controller 40 learning automatic water tap device 1 the use frequency, and according to the use frequency to regulating the electrolytic cell 37 of the power-on time. For the purposes of in detail, controller 40 by the use frequency of learning of the more the greater the shorten the electrolytic cell 37 of the power-on time, in other words, the learning the use frequency of the less the greater the extension of the electrolytic cell 37 of the power-on time.

In addition, in the above-mentioned content, while taking into account the electrolytic cell on 37 and the service life of the (durable years) follow-up guttation control of the elaborated, but is not limited to such a control, also can make the holding hand washer 5 of the basin 3 cleaning is given priority on follow-up guttation control carried out. In this case, since the hand washer 5 of the basin 3 is in the dirty washing after the user, so the best is the controller 40 in each time when washing hands for guttation electrolytic water and use the follow-up guttation.

Below, with reference to Figure 8, for the following reasons in that only during the follow-up guttation of (Figure 7 in indexed symbol T2 period) of the initial period (Figure 7 in indexed symbol T3 period) to generate electrolytic water, in the subsequent period does not generate electrolytic water flows from the common water of a description of the reasons. Figure 8 schematisation expressed cell 37 of the upstream side section 2 flow path 18 and 2 spit-back by the water 13, will conduct follow-up guttation during the article 2 the flow path 18 of the water in the state from the left to the said time sequence. Figure 8 in, for different shapes of said section 2 flow path 18 in the common water and electrolytic water.

First of all, in the beginning of the follow-up guttation, controller 40 paragraph 2 solenoid valve 28 is opened by the opening and closing switching, to the beginning of the cell 37 energized, but because at this moment of the 2 flow path 18 is filled with water in the ordinary, so from section 2 by the water out of the 13 discharge common water (with reference to Figure 8 (A)). Thereafter, the electrolytic cell 37 generating electrolytic water along the article 2 flow path 18 to flow to the downstream side (Figure 8 (B) reference), when the electrolytic water from reaching the article 2 flow path 18 when the downstream end of, that is to say when reaching the article 2 spit-back by the water 13 when (at this moment of the 2 flow path 18 is in the electrolytic water full of), from section 2 spit-back by the water 13 begin to discharge the electrolytic water (with reference to Figure 8 (C)). Thereafter, the controller 40 in the holding part 2 solenoid valve 28 open state, stop the electrolytic tank 37 energized, stop the electrolytic cell 37 to generate electrolytic water. Therefore, the ordinary water is supplied to the article 2 flow path 18, as a result of the 2 flow path 18 in the electrolytic water is top out, so from section 2 by the water out of the 13 discharge electrolytic water, article 2 flow path 18 in the electrolytic water gradually by ordinary water displacement (with reference to Figure 8 (D)). Then, the final article 2 flow path 18 in the electrolytic water virtually not, article 2 flow path 18 is filled with water in the ordinary (with reference to Figure 8 (E)). At this time, controller 40 paragraph 2 solenoid valve 28 from the open switched off, from the end of the section 2 and a water discharge 13 spray guttation, that is to say the end of the follow-up guttation.

So, in this embodiment, the use of electrolysis of water at the end of the follow-up guttation, article 2 flow path 18 become filled with water in the ordinary state. Therefore, to inhibit the electrolytic water staying in the article 2 flow path 18 caused in paragraph 2 flow path 18 and the like is corrosion (deterioration). In this case, controller 40 to the electrolytic cell in the stop 37 is energized, in the following time that and 2 the flow path 18 of the volume (also can be used and included article 2 spit-back by the water 13 volume) than the equivalent of the amount of the ordinary water or more common water along the article 2 flow path 18 by the flow of the time the article 2 solenoid valve 28 is kept as the open, to the section 2 the flow path 18 of the ordinary water supply, in such a way that at the end of the follow-up guttation form the 2 flow path 18 is in the state of the ordinary filled with water.

As an example, section 2 flow path 18 for the volume of 8 cc, article 2 flow path 18 in the flow rate is 5 cc when, for ordinary water full of article 2 flow path 18 need in 1.6 seconds, so the controller 40 to the electrolytic cell in the stop 37 is energized, keep the article 2 solenoid valve 28 open 1.6 seconds, to the section 2 the flow path 18 to supply the ordinary water. In this case, to 3.5 seconds follow-up guttation (equivalent to Figure 7 is shown a prescribed time T2) when, controller 40 in the initial 1.9 seconds (equivalent to Figure 7 is shown a prescribed time T3), making the article 2 solenoid valve 28 is opened to the electrolytic bath under the state of 37 energized, in the subsequent 1.6 seconds, in the stop to the electrolytic cell 37 energized under the state that the article 2 solenoid valve 28 is opened. In the above-mentioned cases, in the initial 1.6 seconds discharge for the ordinary water, in the back of the 1.9 seconds and spits the electrolytic water.

In the above-mentioned example, although 1.6 seconds is from the stop to the electrolytic cell 37 energized from the beginning to the article 2 flow path 18 by ordinary filled with water in the required minimum time, but is not limited to the holding part 2 solenoid valve 28 open the 1.6 seconds, to the section 2 the flow path 18 to supply the ordinary water, also can be to keep the article 2 solenoid valve 28 open than 1.6 seconds longer time, to the section 2 the flow path 18 to supply the ordinary water. So, equivalent to the article 2 flow path 18 supply than the 2 flow path 18 of the carrying things more common water. In the above-mentioned cases, in spit out electrolytic water discharge for a while after the ordinary water, can be used for the ordinary water flushing to the hand washer 5 of the basin 3 and the discharge of the electrolytic water, can inhibit the electrolytic water to the basin 3 or the impact of the sieve plate and the like.

In addition, in the above-mentioned example, when the follow-up guttation, although in from section 2 by the water out of the 13 discharge the electrolytic water to the electrolytic cell after stop 37 energized, stop to the section 2 the flow path 18 to supply the electrolytic water, to the section 2 the flow path 18 to supply the ordinary water, but in another example, also can be in the from clause 2 spit-back by the water 13 after the discharge the electrolytic water to the electrolytic cell do not stop 37 energized, but by reducing the electrolytic tank 37 energized power (mean current or voltage), to the section 2 the flow path 18 to supply the low concentration of the electrolytic water, rather than to the general water.

In this case, controller 40 initially through the paragraph 1 energized power electrolytic cell 37 in the electrolytic bath 37 in generating section 1 concentration of the electrolytic water, and lie between the article 2 flow path 18 from section 2 by the water out of the 13 discharge the article 1 concentration of the electrolytic water, thereafter, through will be lower than the section 1 of the energization power of 2 energized power electrolytic cell 37, thus in the electrolytic cell 37 is lower than that generated in the 1 concentration of article 2 concentration of electrolytic water, and to the section 2 the flow path 18 is supplied to the article 2 concentration of the electrolytic water. For example, as section 1 of the concentration of the electrolytic water, the use of fully sterilizing function of the concentration of the electrolytic water, as article 2 concentration of electrolytic water, of the use of the 2 flow path 18 the influences brought by the very small concentration of the electrolytic water (preferably can be sufficient dilution of article 2 flow path 18 in the filled article 1 concentration of the electrolytic water of the concentration of the electrolytic water). In addition, when the electrolytic cell 37 of article 2 energized power is 0 when, the electrolytic cell 37 of the energization stopping, article 2 concentration is 0, as shown in the above example, common water is supplied to the article 2 flow path 18.

According to this another example, as also is the higher of the spat 1 concentration after the electrolysis of water, to the section 2 the flow path 18 to supply the lower part 2 of the concentration of the electrolytic water, so can be used for the article 2 concentration of electrolytic water dilution of the 2 flow path 18 in the concentration of the electrolytic water, can inhibit the article 2 flow path 18 and the like is corrosion due to electrolytic water (deterioration).

Below, with reference to Figure 9 to Figure 11, of the present invention article 1 embodiment of the above-mentioned basic control (with reference to Figure 7) which were based on another control an example to explain.

Figure 9 is the time diagram of said the invention section 1 of the embodiment 1 control instance. Figure 9 sequentially from above said: from the sensor 14 is supplied to the controller 40 of the sensor signal, from the controller 40 is supplied to the article 2 solenoid valve 28 of the drive signal, from the controller 40 is supplied to the article 1 solenoid valve 25 of the driving signal.

In this, with regard to the above-mentioned basic control the same control, appropriate to omit its description. Specifically, on from time t21 to moment t22 control and time t24 subsequent control, because the basic control is the same, therefore omit its description, only from time t22 to moment t24 control of the note.

In the above-mentioned basic control is from the execution of the for washing hands guttation begin to pass the predetermined period of time T1 when the follow-up guttation, sections 1 control example relates to in the following is carried out under control, namely from the execution of the washing for a prescribed period of time from the start of the guttation T1 after the period before, sensor 14 by the non-detection state is switched to the detection state of the situation. Specifically, in rule 1 in control example, in the instant of the end guttation for washing hands t22 after, a predetermined period of time T1 and before a time t23, because the sensor 14 by the non-detection state is switched to the detection state, so the controller 40 to article 1 solenoid valve 25 is energized, so that the article 1 solenoid valve 25 valve, so that the article 1 spit-back by the water 12 the bubble guttation. In this case, controller 40 from the sensor 14 for detecting the state of the continuous time t23 to time the start of the t24 during the period until, keep the article 1 solenoid valve 25 is a valve opening state, from section 1 spit-back by the water 12 the bubble guttation, that is to say for washing hands for guttation.

So, in the paragraph 1 in control example, in the implementation of the toilet after the guttation for, in the period before the follow-up guttation sensor 14 into a detection state, not by rule 2 spit-back by the water 13 spray guttation, but by the article 1 spit-back by the water 12 the bubble guttation. Therefore, in the implementation of the after guttation for washing hands, in the sensor 14 by the temporary non-detection state switching for the detection state (for example the user hand-washing process temporarily move hands to the sensor 14 outside of the detection range), does not make the follow-up guttation start, but rather to make for washing hands guttation and begin again. That is to say, the user does not need to wait until the end of the follow-up guttation can begin again hand washing.

Below, Figure 10 is the time diagram of said the invention section 1 of the embodiment of 2 control instance. Figure 10 sequentially from above said: from the sensor 14 is supplied to the controller 40 of the sensor signal, from the controller 40 is supplied to the article 2 solenoid valve 28 of the drive signal, from the controller 40 is supplied to the article 1 solenoid valve 25 of the driving signal.

In this, with regard to the above-mentioned basic control the same control, appropriate to omit its description. Specifically, on from time t31 to time t33 control and time t35 later control, because the basic control is the same, therefore omit its description, only from time t34 to time t35 control of the note.

Rule 2 control instance relates to the follow-up guttation in the implementation of the sensor 14 by the non-detection state when the switching is carried out by detecting the state of the control. Specifically, in rule 2 in control example, in the time of the follow-up guttation implementation t34, because the sensor 14 by the non-detection state is switched to the detection state, so the controller 40 to stop the article 2 solenoid valve 28 is energized, so that the rule 2 solenoid valve 28 closed valve (electrolytic cell 37 is in the energization stop electrolytic cell 37 of the electrifying), the suspension 2 spit-back by the water 13 spray guttation, at the same time to rule 1 solenoid valve 25 is energized, so that the article 1 solenoid valve 25 valve, so that the article 1 spit-back by the water 12 the bubble guttation. That is to say, controller 40 the end of the follow-up guttation start for washing hands guttation. In this case, controller 40 from the sensor 14 for detecting the state of the continuous time t34 from the beginning to the time t35 during the period until, keep the article 1 solenoid valve 25 is a valve opening state, from section 1 spit-back by the water 12 the bubble guttation. Then, controller 40 in the instant of the end of guttation for washing hands t35 after the sensor 14 of the non-detection state continue for a prescribed time T1 moment t36, to article 2 solenoid valve 28 is energized, so that the rule 2 solenoid valve 28 opening, by the article 2 spit-back by the water 13 spray guttation, that is to say once again follow-up of the guttation.

So, in the section 2 in the control example, the follow-up guttation in the implementation of sensor 14 into a detection state, the suspension 2 spit-back by the water 13 spray guttation, from section 1 spit-back by the water 12 the bubble guttation, that is to say the suspension of follow-up guttation out for washing hands guttation. Therefore, the user does not need to wait until the end of the follow-up guttation can be used for washing hands. In addition, when the electrolytic water splashes when the hands of the user, according to the concentration of the electrolytic water causing the produce the skin chapping or residual electrolytic water specific odor (chlorine smell and the like) of the situation, but by the follow-up guttation in the implementation of sensor 14 into the detected state of the stopped follow-up guttation, thereby preventing such electrolytic water splashes due to the hands of the user to the problems arising.

Below, Figure 11 is the time diagram of said the invention section 1 of the embodiment of the 3 control instance. Figure 11 above expressed from the controller 40 is supplied to the article 2 solenoid valve 28 of the driving signal, the lower part thereof expressed from the controller 40 is supplied to the electrolytic bath 37 of the driving signal. In this, with regard to the above-mentioned basic control the same control, appropriate to omit its description.

In the above-mentioned basic control, although different when on the paragraph 2 solenoid 28 energized and the electrolytic bath 37 of the electrifying, but in article 2 solenoid valve 28 after the beginning of the beginning of the energization of the cell 37 of the electrifying, however in article 3 in the control example, controller 40 in addition to the outside the control, not at the same time stop section 2 solenoid valve 28 and stop the energization of the cell 37 of the electrifying, but the electrolytic cell 37 after the stop of energization of the stop section 2 solenoid 28 energized. Specifically, the controller 40 at the time t41 to article 2 solenoid valve 28 is energized, and in the following moment t42 the electrolytic tank 37 is energized, at the time t43 stop electrolytic cell 37 energized, and in the following moment t44 stop section 2 solenoid 28 energized. For example, controller 40 in the follow-up of the electrolytic water is generated in the implementation of guttation sensor 14 into a detection state, in accordance with the electrolytic cell of the stay as above 37 and section 2 solenoid 28 energized.

So, it is not the simultaneously stop section 2 solenoid valve 28 and stop the energization of the cell 37 of the electrifying, but rather in the electrolytic bath 37 after the stop of energization of the stop section 2 solenoid 28 energized, this is because in paragraph 2 solenoid valve 28 is switched from the open to the closed time consuming a large amount of power, so it is necessary to in the switching time of the electrolytic cell in 37 of the electrifying has ceased, in the power stability during make article 2 solenoid valve 28 action. In addition, because of the to the article 2 solenoid valve 28 and electrolytic cell 37 during the energization of the two sides (from time t42 to time t43 period) to consume a large amount of electric power, so that the to the article 2 solenoid valve 28 electric power to be supplied to keep the appropriate interval can also, specifically to suspend article 2 solenoid valve 28 can also be energized. This is because once the article 2 solenoid valve 28 after opening the valve, even if the temporarily to article 2 solenoid 28 energized, article 2 solenoid valve 28 also almost not closed, can keep the article 2 solenoid valve 28 is actually a valve opening state.

Below, with reference to Figure 12 and Figure 13, of the present invention article 1 embodiment controller 40 of a description of the implementation of the control flow. Figure 12 is the flowchart of the present invention indicated that the section 1 of the embodiment for washing hands guttation relates to control flow of the flow chart, Figure 13 is expressed in fig. 12 as shown in the flow chart of the present invention after section 1 embodiment of the control of the follow-up guttation involved procedure. In addition, Figure 12 and Figure 13 shown is in the basic control flow control (with reference to Figure 7) in the application of the rule 1 to rule 3 control example (with reference to Figure 9 to Figure 11) of the control flow.

First of all, to Figure 12 of the present invention shown in section 1 of the embodiment for washing hands guttation relates to a description of the control flow.

Initially, in step S11, the controller 40 determines from the sensor 14 of the sensor signal has been investigated by the concern trades as the opening, in other words determining sensor 14 has been investigated by the non-detection state is switched to the detection state. As a result, sensor signal is not by the concern trades is on (step S11: no), once again carrying out a step S11 of the judge. That is to say, controller 40 in the sensor signal before the concern trades for the success of the repeatedly performing step S11 of the judge.

On the other hand, sensor signal has been by the concern trades is on (step S11: is), proceed to step S12, controller 40 to article 1 solenoid valve 25 is energized, so that the article 1 solenoid valve 25 opening, so that the article 1 spit-back by the water 12 perform the ordinary water bubble guttation, that is to say for washing hands for guttation.

Next, in the step S13, the controller 40 determines from the sensor 14 of the sensor signal has been investigated by the open switch a wire, that is to say determining sensor 14 has been investigated by the detection state switching is a non-detection state. As a result, sensor signal does not by opening switch is turned off (step S13: no), once again carrying out a step S13 of the judge. That is to say, controller 40 in the sensor signal by the open switch is off is repeatedly carried out before step S13 of the judge. In this case, controller 40 to continue to rule 1 solenoid valve 25 is energized, keep the article 1 electromagnetic valve 25 and a valve opening state, thus continue for washing hands guttation.

On the other hand, sensor signal has been by opening switch is turned off (step S13: is), proceed to step S14, the controller 40 to stop the article 1 solenoid valve 25 is energized, so that the article 1 solenoid valve 25 closing valve, the end of the article 1 spit-back by the water 12 of bubble guttation, that is to say the end of the for washing hands guttation. Thereafter, into the Figure 13 shown in the step S20.

Below, to Figure 13 of the present invention shown in section 1 embodiment of the control of the follow-up guttation relates to a description of the procedure.

Initially, in step S20, controller 40 determines from the sensor 14 of a wire sensor whether the signal, that is to say determining sensor 14 as to whether the non-detection state. As a result, sensor signal is not turned off (step S20: no), that is to say the sensor signal has been by the concern trades is on, return to Figure 12 indicated by the step S12. In this case, controller 40 as described above, to the article 1 solenoid valve 25 is energized, so that the article 1 solenoid valve 25 opening, so that the article 1 spit-back by the water 12 perform the ordinary water bubble guttation, again for washing hands guttation.

On the other hand, sensor signal is turned off (step S20: is), proceed to step S21, the controller 40 judges from the toilets for guttation starting from the end of to have been made with 3 seconds (equivalent to Figure 7 is shown a prescribed time T1). As a result, from the toilets for guttation starting from the end not after 3 seconds (step S21: no), return to step S20, once again carrying out a step S20 and S21 decision. In this case, the controller 40 judges whether the signal is on the side of the closing wait 3 seconds after.

On the other hand, from the toilets for guttation starting from the end has been 3 seconds (step S21: is), proceed to step S22, the controller 40 to make the LED15 is open. Immediately after, at step S23, controller 40 to article 2 solenoid valve 28 is energized, so that the rule 2 solenoid valve 28 opening, followed immediately, in step S24, the controller 40 to the electrolytic cell 37 energized, the electrolytic cell 37 to generate electrolytic water. Therefore, controller 40 to make the article 2 spit-back by the water 13 to carry out electrolysis of water spray guttation, that is to say follow-up guttation.

In addition, strictly speaking, from the toilets for guttation starting from the end of after 3 seconds of time point so that the article 2 solenoid valve 28 valve, controller 40 from the toilets for guttation starting from the end of after 3 seconds before the time point, that is to say from the toilets for guttation starting from the end of the after less than 3 seconds of a prescribed period of time, the LED15 is open.

Next, in step S25, the controller 40 determines from the sensor 14 of a wire sensor whether the signal, that is to say determining sensor 14 as to whether the non-detection state. As a result, sensor signal is not turned off (step S25: no), that is to say the sensor signal has been by the concern trades is on, proceed to step S26. In this case, in step S26, the controller 40 to stop the electrolytic tank 37 is energized, the end of the electrolytic cell 37 to generate electrolytic water. Immediately after, at step S27, controller 40 in the LED15 of a wire at the same time, stop to the article 2 solenoid valve 28 is energized, so that the rule 2 solenoid valve 28 closed valve. Therefore, controller 40 of the end 2 and a water discharge 13 spray guttation, that is to say the end of the follow-up guttation. Thereafter, return to Figure 12 is shown in the step S12, controller 40 as mentioned above to the article 1 solenoid valve 25 is energized, so that the article 1 solenoid valve 25 opening, so that the article 1 spit-back by the water 12 perform the ordinary water bubble guttation, again for washing hands guttation.

On the other hand, sensor signal is turned off (step S25: is), proceed to step S28, controller 40 determines whether or not the follow-up guttation after the start has been 1.9 seconds (equivalent to Figure 7 is shown a prescribed time T3). As a result, the follow-up guttation after the start of the passing of 1.9 seconds (step S28: no), returning to step S25, once again carrying out a step S25 and S28 decision. In this case, the controller 40 judges whether the signal is on the side of the closing wait 1.9 seconds after.

On the other hand, has been through the follow-up guttation after the start of the 1.9 seconds (step S28: is), proceed to step S29, controller 40 to stop the electrolytic tank 37 is energized, the end of the electrolytic cell 37 to generate electrolytic water.

Next, in step S30, the controller 40 determines from the sensor 14 of a wire sensor whether the signal, that is to say determining sensor 14 as to whether the non-detection state. As a result, sensor signal is not turned off (step S30: no), that is to say the sensor signal has been by the concern trades is on, proceed to step S27. In this case, in step S27, the controller 40 in the LED15 of a wire at the same time, stop to the article 2 solenoid valve 28 is energized, so that the rule 2 solenoid valve 28 closed valve. Therefore, controller 40 of the end 2 and a water discharge 13 spray guttation, that is to say the end of the follow-up guttation. Thereafter, return to Figure 12 is shown in the step S12, controller 40 as mentioned above to the article 1 solenoid valve 25 is energized, so that the article 1 solenoid valve 25 opening, so that the article 1 spit-back by the water 12 perform the ordinary water bubble guttation, again for washing hands guttation.

On the other hand, sensor signal is turned off (step S30: is), proceed to step S31, controller 40 determines whether or not the follow-up guttation after the start has been 3.5 seconds (equivalent to Figure 7 is shown a prescribed time T2). As a result, the follow-up guttation after the start of the passing of 3.5 seconds (step S31: no), returning to step S30, once again carrying out a step S30 and S31 decision. In this case, the controller 40 judges whether the signal is on the side of the closing wait 3.5 seconds after.

On the other hand, has been through the follow-up guttation after the commencement of 3.5 seconds (step S31: is), proceed to step S32, controller 40 in the LED15 of a wire at the same time, stop to the article 2 solenoid valve 28 is energized, so that the rule 2 solenoid valve 28 closed valve. Therefore, controller 40 of the end 2 and a water discharge 13 spray guttation, that is to say the end of the follow-up guttation.

(Article 1 the effect of the embodiment)

Below, the present invention relates to article 1 embodiment of automatic water tap device of a description of the effect.

According to the article 1 embodiment, because the sensor 14 for detecting the state of the washing hands for guttation, when the sensor 14 into the end of the non-detection state and for washing hands guttation, and thereafter follow-up guttation (with reference to Figure 7), so in the use of toilets for hand washing water discharge out of the dirt it is possible to adhere to the hand washer 5 of the basin 3 and the state of the drying, when adhered to, can carry out a proper follow-up guttation, can at the same time inhibiting guttation waste, inhibit the above-mentioned dirt to adhere to the hand washer 5 of the basin 3 and the state of the dry cement. Therefore, can keep the hand washer 5 of the basin 3 and cleaning. In particular according to the paragraph 1 embodiment, due to the use of electrolytic water follow-up guttation, so can effectively maintain the hand washer 5 of the basin 3 and cleaning.

And, although the use of toilets for hand washing water discharge out of the water (sewage) by the presence of the range than for washing hands guttation of guttation range greater trend, but according to the paragraph 1 embodiment, because of the use of and use for washing hands water discharge of the water from the bubble guttation compared with the spit water discharge angle of greater spray spit-back water for follow-up guttation, so can the small flow to the large-scale guttation, can at the same time inhibiting guttation waste, effectively retaining hand washer 5 of the basin 3 and cleaning. In this case, although the user is very difficult to predict spray guttation of guttation range R11, but according to the paragraph 1 embodiment, because of the LED15 irradiation and spray guttation of guttation range R11 substantially the same range R12 (with reference to Figure 4), it is possible to spray guttation of guttation range R11 placed in to the user, can inhibit water falls into the user would not want to fall into place. In particular according to the paragraph 1 embodiment, because through the LED15 spray guttation before the beginning of the light emitted from the pre-notification to the user of the guttation range spray guttation R11 (with reference to Figure 7), so can effectively inhibit the water falls into the user would not want to fall into place.

And, according to the paragraph 1 embodiment, since the sensor for washing hands guttation after the end 14 of the non-detection state has continued for the given time follow-up guttation (with reference to Figure 7), the notification to the user can be used at the end of the subsequent and guttation follow-up guttation start. When the follow-up guttation electrolytic water splashes when the hands of the user, while according to the concentration of the electrolytic water in the presence of the produce the skin chapping or residual electrolytic water by the smell of the specific (chlorine smell and the like) of the situation, but by as mentioned above to the user informing the beginning of the follow-up guttation, can properly prevent the electrolytic water splashes to the hands of the user to the problems arising.

And, according to the paragraph 1 embodiment, because the toilets for guttation at that period of follow-up guttation before the sensor 14 into a detection state the bubble guttation rather than spray guttation (with reference to Figure 9), so the rear sensor for washing hands by the temporary guttation non-detection state switching for the detection state (for example the user hand-washing process temporarily move hands to the sensor 14 outside the detection range of the), can not make the subsequent guttation start is suitably of the hand for guttation and begin again. That is to say, the user does not need to wait until the end of the follow-up guttation can begin again hand washing.

And, according to the paragraph 1 embodiment, because in the course of the follow-up guttation of sensor 14 into a detection state to suspend the spray guttation but the bubble guttation, that is to say the suspension of follow-up guttation out for washing hands guttation (with reference to Figure 10), so the user does not need to wait until the end of the follow-up guttation can be used for washing hands, at the same time can prevent as mentioned above due to the electrolytic water splashes to the hands of the user to the problems arising.

And, according to the paragraph 1 embodiment, the commencement of the follow-up guttation when, as in the paragraph 2 solenoid valve 28 after the beginning of the beginning of the energization of the cell 37 energized, in the power stable condition the beginning of the electrolysis cell 37 energized, at the same time the end of the follow-up guttation when, in the electrolytic bath 37 after the stop of energization of the stop section 2 solenoid 28 energized, in the power stability under the condition of article 2 solenoid valve 28 from the open to the closed action (with reference to Figure 11), even if the small capacity of the power supply is capable of suitably response, the device can be miniaturized.

And, according to the paragraph 1 embodiment, because they do not each time when washing hands for guttation follow-up guttation, but every a predetermined number of times when the guttation for washing hands follow-up guttation, or through the study of the automatic water tap device 1 according to the use frequency of the use frequency and to regulating the electrolytic cell 37 of the power-on time, so can lighten the given cell 37 of the load, prolonging the 37 of the service life (durable years).

In addition, according to rule 1 embodiment, in the follow-up guttation when, because the from section 2 by the water out of the 13 discharge electrolytic water stop after electrolytic cell 37 of the electrifying, stop to the section 2 the flow path 18 to supply the electrolytic water, to the section 2 the flow path 18 to supply the ordinary water (with reference to Figure 7 and Figure 8), so that through the common water by the supply of the discharge section 2 flow path 18 in the electrolytic water thus for ordinary water displacement, can be dilution of the 2 flow path 18 in the concentration of the electrolytic water (supply the mixture is common when the water, the article 2 flow path 18 in the electrolytic water almost fully discharged, so that a common water full of article 2 flow path 18 in). Therefore, due to the retention of the electrolytic water can be suppressed at the 2 flow path 18 caused in paragraph 2 flow path 18 and the like is corrosion (deterioration). In this, in order to inhibit section 2 flow path 18 or the like, may consider adopting the method of adjusting the concentration of the electrolytic water, in this case, the need to electrolytic water is adjusted to corrosion inhibiting concentration, but according to the paragraph 1 embodiment, because as mentioned above to the article 2 flow path 18 to supply the ordinary water, it is not necessary to take into account the 2 flow path 18 and the like corrosion, can use various concentration of the electrolytic water.

On the other hand, according to the paragraph 1 embodiment, in the tip portion of the article 1 spit-back by the water 12 of article 1 spit-back nozzle 12 a, paragraph 2 spit-back by the water 13 of section 2 spit-back outlet 13 a and the sensor 14 of the automatic water tap device 1 in, because the article 1 spit-back nozzle 12 a set in the sensor 14 with the article 2 spit-back outlet 13 a between (with reference to Figure 2 (B)), so can make the sensor 14 and 2 out of the outlet 13 a left, can inhibit because the sensor 14 detects from section 2 spit-back outlet 13 a spray discharge of water as a result of the error guttation. In particular according to the paragraph 1 embodiment, as in the paragraph 1 spit-back nozzle 12 a with the article 2 spit-back outlet 13 a is also provided with between the LED15 (with reference to Figure 2 (B)), so can make the sensor 14 and 2 out of the outlet 13 a more left, can effectively inhibit the above error guttation. In addition, because of the LED15 set in the article 2 spit-back outlet 13 a near, through the LED15 can be irradiated with the light emitted by the appropriate rule 2 spit-back by the water 13 of the guttation range R11.

In addition, according to rule 1 embodiment, because in than the 2 out of the outlet 13 a is in front of the side matches the front is provided with a sensor 14 (with reference to Figure 2 (B)), so with the than the 2 out of the outlet 13 a is assigned to the rear the rear side of the sensor 14 is compared with the, the user does not need in order to make the sensor 14 detecting the hand and the hard the hand extends to the rear side of the can. In addition, because the ratio sensor 14 rearward of the side matches with the rear of the 2 out of the outlet 13 a (with reference to Figure 2 (B)), so with the ratio sensor 14 disposed in the front side of the front section 2 spit-back outlet 13 a compared with the case where, from section 2 spit-back outlet 13 a spray discharge of water to the user's arm, body and other do not hope to be wetted part.

In addition, according to rule 1 embodiment, because the sensor 14 disposed in the following way, sensor 14 of the detection direction of the A23 towards gradually leave the article 2 spit-back by the water 13 of the guttation direction A22 direction, in other words, because the sensor 14 is disposed in the following way, along the sensor 14 of the detection direction of the A23 straight line L13 in from the side of the front section 2 and a water discharge 13 of section 2 spit-back outlet 13 a in the vertical direction in the center of a straight line extending on the L12 does not intersect (with reference to Figure 5), so the sensor 14 pointing range R13 in very low detection precision of the part (that is to say pointing in the range R13 in from sensor 14 very distant part of) with article 2 spit-back by the water 13 of the guttation range R11 cross, so it can be effectively suppressed because the sensor 14 detects from section 2 spit-back outlet 13 a spray discharge of water as a result of the error guttation.

In addition, according to rule 1 embodiment, as a result of the 1 spit-back by the water 12 and section 2 by the water out of the 13 are disposed in such a manner that, article 1 spit-back by the water 12 of guttation direction A21 and 2 spit-back by the water 13 of the guttation direction A22 towards the direction of gradually away from each other, in other words, article 1 spit-back by the water 12 and section 2 by the water out of the 13 are disposed in such a manner that, from section 1 spit-back nozzle 12 a in the vertical direction in the center of a straight line extending on the L11 in the front side and from section 2 spit-back outlet 13 a in the vertical direction in the center of a straight line extending on the L12 does not intersect (with reference to Figure 5), so can make the article 2 spit-back by the water 13 towards the below the spray guttation, can properly prevent from section 2 spit-back by the water 13 to spray discharge water of the user.

In addition, according to rule 1 embodiment, because in than the 1 out of the outlet 12 a to the rear of the side matches with the rear of the 2 out of the outlet 13 a (with reference to Figure 2 (B)), so it may be appropriate to prevent from section 1 spit-back nozzle 12 a drop of the water drops to the article 2 spit-back outlet 13 a on. In this case, according to the paragraph 1 embodiment, by taking into account the article 1 spit-back outlet 12 a of the position of the article 2 spit-back by the water 13 toward the, it is possible to appropriately prevent from section 2 spit-back outlet 13 a spray discharge water of the to the article 1 spit-back nozzle 12 a.

(Article 2 embodiment)

Below, the present invention relates to article 2 in the embodiment controller 40 by the control of the note. In the above-mentioned article 1 in the embodiment, in the toilet for guttation when carry only 1 spit-back by the water 12 of bubble guttation, but in the section 2 in the embodiment, in the toilet for guttation when to carry out the not only 1 spit-back by the water 12 of bubble guttation, also in paragraph 2 spit-back by the water 13 spray guttation. Specifically, in the section 2 in the embodiment, the controller 40 when in the guttation for washing hands, initially a predetermined period of time section 2 spit-back by the water 13 spray guttation, then rule 1 spit-back by the water 12 of bubble guttation.

In addition, the following, with regard to the above-mentioned article 1 embodiment the same control, appropriate omit its description, only with the article 1 embodiment different control description of the. In other words, in this does not carry out a special explanation of control with the article 1 in the same embodiment.

Figure 14 is the time diagram of said the invention article 2 embodiment of the basic control. Figure 14 sequentially from above said: from the sensor 14 is supplied to the controller 40 of the sensor signal, from the controller 40 is supplied to the article 2 solenoid valve 28 of the drive signal, from the controller 40 is supplied to the article 1 solenoid valve 25 of the drive signal, from the controller 40 is supplied to the electrolytic bath 37 drive signal, from the controller 40 is supplied to the LED15 driving signal.

In this, on the moment t54 subsequent control, as a result of the article 1 embodiment of the same basic control, therefore omit its description, only from the time t51 to the time t54 control of the note.

First of all, at the time t51, sensor signal by the concern trades is open, that is to say the sensor 14 by the non-detection state is switched to the detection state. At this time, controller 40 to article 2 solenoid valve 28 is energized, so that the rule 2 solenoid valve 28 opening, so that the rule 2 spit-back by the water 13 spray guttation. In this case, controller 40 does not make the LED15 is open, but not to the electrolytic cell 37 energized, that is to say not in the electrolytic bath 37 generating electrolytic water, but rather to make part 2 spit-back by the water 13 perform the ordinary water spray guttation. Controller 40 for washing hands guttation when in the initial stage of the as of guttation adopt such a spray guttation. Moreover, the controller 40 from the article 2 spit-back by the water 13 spray guttation at the start of a t51 to begin to pass a predetermined time T5 (such as 3 seconds) time t52, by stopping to the article 2 solenoid valve 28 is energized, so that the rule 2 solenoid valve 28 closing valve, thus ending the article 2 spit-back by the water 13 spray guttation.

Then, in the from clause 2 spit-back by the water 13 of the instant of the end of the spray guttation t52 begin to pass a certain degree of time (for example 0.5 seconds) time t53, controller 40 to article 1 solenoid valve 25 is energized, so that the article 1 solenoid valve 25 opening, so that the article 1 spit-back by the water 12 perform the ordinary water bubble guttation. Controller 40 in for washing hands guttation when carried out as spray guttation after adopting the bubbles by guttation guttation. Thereafter, at the time t54, sensor signal by switching a wire opening, that is to say the sensor 14 by the detection state switching is a non-detection state. At this time, the controller 40 to stop the article 1 solenoid valve 25 is energized, so that the article 1 solenoid valve 25 closing valve, the end of the article 1 spit-back by the water 12 of bubble guttation. By this, the end of the for washing hands guttation. Thereafter, controller 40 in accordance with the article 1 embodiment the same procedures follow-up guttation.

In addition, the best of the hand when the guttation for specified time for the spray guttation T5 can be adjusted. In particular, preferably in the automatic water tap device 1 and the adjusting part of the set-up switch, according to the automatic water tap device 1 use environment (automatic water tap device 1 of the user characteristic, automatic water tap device 1 setting places and the like), so that the administrator can use the adjusting part for adjusting a prescribed time T5.

Below, with reference to Figure 15, of the present invention article 2 embodiment controller 40 the description of the implementation of the control process. Figure 15 is the flowchart of the invention of the said 2 embodiment involved for washing hands guttation control flow.

In addition, in the paragraph 2 embodiment of the guttation for washing hands after the end of the control flow to, also the implementation of the above Figure 13 shown in the relates to the control of the follow-up guttation procedure.

First, in step S41, controller 40 determines from the sensor 14 of the sensor signal has been investigated by the concern trades as the opening, in other words determining sensor 14 has been investigated by the non-detection state is switched to the detection state. As a result, sensor signal is not by the concern trades is on (step S41: no), once again carrying out a step S41 decision. That is to say, controller 40 in the sensor signal before the concern trades for the success of the repeatedly performing step S41 decision.

On the other hand, sensor signal has been by the concern trades is on (step S41: is), proceed to step S42, controller 40 to article 2 solenoid valve 28 is energized, so that the rule 2 solenoid valve 28 opening, so that the rule 2 spit-back by the water 13 spray guttation. Therefore, the beginning of the washing hands for guttation.

Next, in the step S43, the controller 40 judges as for washing hands guttation spray guttation after the beginning not through whether 3 seconds (equivalent to Figure 14 is shown a prescribed time T5). As a result, spray guttation after the beginning of the not after 3 seconds (step S43: is), proceed to step S44, the controller 40 determines from the sensor 14 of the sensor signal has been investigated by the open switch a wire, that is to say determining sensor 14 has been investigated by the detection state switching is a non-detection state. As a result, sensor signal has been by opening switch is turned off (step S44: is), proceed to step S45, the controller 40 to stop the article 2 solenoid valve 28 is energized, so that the rule 2 solenoid valve 28 closing valve, the end of the rule 2 spit-back by the water 13 spray guttation. By this, the end of the guttation for washing hands. Thereafter, enter the said Figure 13 shown in the step S20.

On the other hand, the sensor signal is not by opening switch is turned off (step S44: no), returning to step S43, once again carrying out a step S43 and S44 judge. That is to say, the controller 40 judges whether the signal has one side of the opening is switched off by the wait 3 seconds after. In this case, the controller 40 through the continued to the article 2 solenoid 28 energized, keep the article 2 solenoid valve 28 and a valve opening state, thus to continue 2 spit-back by the water 13 spray guttation.

On the other hand, spray guttation started after 3 seconds (step S43: no), proceed to step S46, controller 40 to stop the article 2 solenoid valve 28 is energized, so that the rule 2 solenoid valve 28 closing valve, the end of the rule 2 spit-back by the water 13 spray guttation.

Next, enter step S47, controller 40 to article 1 solenoid valve 25 is energized, so that the article 1 solenoid valve 25 valve, the beginning of the paragraph 1 spit-back by the water 12 of bubble guttation. In this case, controller 40 from the spray guttation starting from the end of the stipulated time (for example 0.5 seconds) after, the beginning of such bubble guttation.

Next, enter step S48, controller 40 determines from the sensor 14 of the sensor signal has been investigated by the open switch a wire, that is to say determining sensor 14 has been investigated by the detection state switching is a non-detection state. As a result, sensor signal does not by opening switch is turned off (step S48: no), once again carrying out a step S48 of judging. That is to say, controller 40 in the sensor signal by the open switch is off is repeatedly carried out before the step S48 of judging. In this case, the controller 40 through the continued to rule 1 solenoid valve 25 is energized, keep the article 1 electromagnetic valve 25 and a valve opening state, thus to continue 1 spit-back by the water 12 of bubble guttation.

On the other hand, sensor signal has been by opening switch is turned off (step S48: is), proceed to step S49, the controller 40 to stop the article 1 solenoid valve 25 is energized, so that the article 1 solenoid valve 25 closing valve, the end of the article 1 spit-back by the water 12 of bubble guttation. By this, the end of the guttation for washing hands. Thereafter, enter the said Figure 13 shown in the step S20.

In addition, in the implementation of 2 control flow of the embodiment of the case, in the above-mentioned Figure 13 shown in the step S20 of "no" is judged and when carrying out a step S27 after the control of the, return to Figure 15 as shown by a step S47. Specifically, in the section 2 in the embodiment, it is also for washing hands guttation after in the implementation, in the period before the follow-up guttation sensor 14 into a detection state, not in paragraph 2 spit-back by the water 13 spray guttation, the paragraph 1 spit-back by the water 12 of bubble guttation, at the same time the implementation of the sensor in the follow-up guttation of 14 into detection state, the suspension 2 spit-back by the water 13 spray guttation, paragraph 1 spit-back by the water 12 of bubble guttation.

(Article 2 the effect of the embodiment)

Below, the present invention relates to article 2 embodiment of automatic water tap device of a description of the effect. In this, with only the above-mentioned article 1 embodiment of a description of the effect of different.

According to the article 2 embodiment, the sensor 14 detects the period of the detected object, initially from the article 2 spit-back by the water 13 spray guttation, when the spray guttation beginning a predetermined time after T5 (such as 3 seconds) is stopped when the spray guttation, from section 1 spit-back by the water 12 the bubble guttation, at the initial stage can use the flow small but rapid velocity spray guttation efficiently washing hands, at the same time can then use flow and large air bubbles guttation, not only can the toilet, or the storage of washing can also be carried out efficiently. Therefore, can at the same time to ensure that the convenience of the user of the proper water-saving. In particular according to rule 2 embodiment, because the automatic switching is spray guttation after bubble guttation, so the action of the washing hands outside (to wash or the storage) time, or the use of the soap such as hands washing for a long time and during operation, the user does not need to carry out special operation or consciously operation can also be automatically switched into the bubble guttation, it can ensure the high convenience.

In addition, according to the article 2 embodiment, because from the stop section 2 spit-back by the water 13 spray guttation beginning after a certain degree of time (for example 0.5 seconds) to commence 1 spit-back by the water 12 of bubble guttation, that is to say in the spray guttation and bubble water discharge between the temporary stop, so can the user notification spray guttation end. Therefore, the user can be given the opportunity to suspend washing hands, and can be effectively water-saving.

In addition, according to the article 2 embodiment, due to the toilet for guttation can be changed specified time for the spray guttation T5 forms in a manner, so according to the automatic water tap device 1 use environment, by letting the user's convenience and water-saving in a certain priority to appropriate adjustment spray guttation prescribed time T5. For example, it is difficult to wash the dirt attached to the hand of the need of a long time under the environment of washing hands, can shorten the spray guttation prescribed time T5, so that the convenience of the user than water-saving more priority.

In addition, according to the article 2 embodiment, in the sensor 14 into detection less than detected, and for washing hands guttation stop in a predetermined time after T1 (for example 3 seconds) before the sensor 14 is detected under the condition that the detected objects, because they do not once again in paragraph 2 spit-back by the water 13 spray guttation, but in paragraph 1 spit-back by the water 12 of bubble guttation, so it is appropriate to ensure that the convenience of the user. For example, the hands of the user in the process temporarily handle the mobile to the sensor 14 after the detection range of the outside, to the water or for hand washing of soap, because they do not spray guttation but the bubble guttation, so can ensure that the convenience of the user.
