Cooling device e.g. household refrigerator, has usable area cooled by cooling aggregate, vacuum pump provided for generating low-pressure in inner area of low-pressure container, and coupling for connecting container with pump

Area of the invention the invention concerns a cooler, in particular a refrigerator, with a refrigerator and with a store coolable with the refrigerator. Background it is well-known that meals can be stored at low temperatures longer. It continues to be well-known that most meals are longer storable also with negative pressure. Representation of the invention it is task of the available invention to make a cooler available of the initially mentioned kind in which the cooling property can be for a long time stored. This task is solved from the cooler in accordance with requirement 1. At least one part of the store of the cooler is formed accordingly by at least one Unterdruckbehälter. The cooler continues to possess a vaccum pump for producing a negative pressure in the interior of the Unterdruckbehälters. The cooling property can be stored in the Unterdruckbehälter thus at low temperatures and low pressure, whereby a long storage time results. Favourably the Unterdruckbehälter can be taken from the store. For connection with the vaccum pump a clutch can be planned in this case. This clutch can e.g. exhibit a first, stationarily part arranged at the cooler as well as a second, firmly part arranged at the Unterdruckbehälter, whereby these two parts can be interconnected essentially with one another gas-tight. In this connection the term is to be understood “stationarily” in such a way that it can remain first part with withdrawal of the Unterdruckbehälters in the cooler. The first part of the clutch can exhibit a first valve, which can be opened by attachment of the second part of the clutch at the first part. In other words this valve remains thus closed, until the Unterdruckbehälter is attached. In this way no air enters the pump the negative pressure system of the cooler and is not loaded with nonusage of the clutch. At the second part of the clutch a check valve can be arranged, which closes, if in the interior of the Unterdruckbehälters a lower pressure prevails than at the delta of the second part of the clutch. Such a out-arranged Unterdruckbehälter also still retains its negative pressure after the loosening of the clutch or with a leakage around negative pressure system of the cooler. The Unterdruckbehälter favourably possesses a floor part and a cover, which enclose together the interior of the Unterdruckbehälters. Preferably the second part of the clutch is appropriate at the cover in this case, so that the cover contains the container-lateral coupling system as it were, while the floor part can be out-arranged optimal as photograph container for the cooling property (e.g. which concerns temperature stability, Design and Waschbarkeit). Alternatively to the arrangement at the cover the second part of the clutch can be arranged however also at the floor part, e.g. at a lateral wall or downward. The Unterdruckbehälter can be out-arranged also as drawer of the cooler. Also in this case the Unterdruckbehälter preferably exhibits a cover. This can be e.g. so out-arranged that he opens automatically when (partial or complete) pulling the Unterdruckbehälters out and/or closes automatically when pushing the Unterdruckbehälters in, which simplifies the handling. In particular the floor part of the Unterdruckbehälters can, as mentioned for which respective application are optimized, so e.g. for heating up the cooling property in the steam equipment, in the baking-oven or on the stove, in which case it should be temperature-steadily to at least 100 °C (for steam refining), in particular at least 150 °C (for regenerating), in particular at least 300 °C (for baking) and in particular to at least 400 °C (for refining on the cook field or to the Grillieren), and consist for example of metal (e.g. high-grade steel) can. At the Unterdruckbehälter a pressure sensor can be arranged, in order to supervise the negative pressure in its interior. This pressure sensor can be formed e.g. by a “crack frog”, as it admits from preserving containers is, or also it can concern also an electronic or mechanical pressure probe with announcement. The Unterdruckbehälter can exhibit also a water tank, which is located in gas exchange connection with the interior of the Unterdruckbehälters. By gas exchange connection thereby a connection is to be understood, the one transition of water vapour from the water tank to the interior of the Unterdruckbehälters permitted. Thus can be worked against to draining the stored material. The vaccum pump is to lower the pressure in the Innendraum of an attached Unterdruckbehälters on under 0.5 bar, in particular under 0.1 bar, depending upon application, favourably so out-arranged that it permits it. The invention can be used favourably in a refrigerator, in particular a household refrigerator. It can be used however e.g. also in cold treatment equipment, i.e. in equipment, in which the cooling property is stored with under 0 °C. Short description of the designs further arrangements, advantages and applications of the invention result from the dependent requirements and from the following description on the basis the figures. Show: Fig. 1 Fig. 2 Fig. 3 Fig. 4 a schematic representation of the most important components of an execution of the cooler, a schematic cut by a Unterdruckbehälter hung up in the frame part, a detailed representation of an execution of the clutch and one as Unterdruckbehälter out-arranged drawer. Ways to the execution of the invention the cooler in accordance with Fig. 1 is out-arranged as household refrigerator and possesses into well-known way a thermally isolated housing 1, which encloses a store 2. In the store 2 well-known arrangements are arranged for the admission of cooling property, as Tablare 3 or a cold treatment compartment of 4th far ones is e.g. an only schematically represented refrigerator 5 well-known building method intended, which a heat pump can be e.g. covered and be cooled with that the store 2. A control 6 serves to steer the components of the cooler. Further a frame part 7 is arranged in the store 2, which is out-arranged e.g. in the kind of a Tablars, but photograph openings 8 for the admission of Unterdruckbehältern 9 exhibits. The Unterdruckbehälter 9 serve, as mentions above, for it, to store cooling property with reduced pressure. For this is intended in the cooler of a far vaccum pump 10 for producing a negative pressure in a negative pressure system. This negative pressure system covers a line 11, which at the vaccum pump 10 is attached, as well as a evacuation system in the frame part 7. in the available example. Fig. 2 a Unterdruckbehälter 9 arranged in the frame part 7. the Unterdruckbehälter 9 shows possesses an interior 12, in which the cooling property under reduced pressure is stored by at the most 0,5 bar (is called depending upon application, between 0 and 0.5 bar). A storage with a pressure of under 0.1 bar can be meaningful in particular for drying cooling property which can be stored. Within the range of 0.1 to 0,5 bar the pressure can be selected e.g. dependent on the desired humidity and the presence on liquids. The interior istvon a cover enclosed 14 and a Bodentei115, whereby the cover 14 and the Bodentei115 the lower part of the Unterdruckbehälters 9 defines the top. The cover 14 possesses a boundary region 16, which towers above the Bodentei115 each other at least in a place, preferably in at least two in relation to lying sides, laterally. As from Fig. evidently, the Unterdruckbehälter 9 is held for 2 at these laterally supernatant boundary regions 16 of the cover 14 by the frame part 7, i.e. supported from downside. Each Unterdruckbehälter 9 can be connected by a clutch 18 with the negative pressure system and thus the vaccum pump. So that the Unterdruckbehälter 9 can be taken from the cooler, this clutch 18 is out-arranged solvable. The clutch 18 is on the one side connected with a Saugkanal 20 of the evacuation system in the frame part 7, whereby the Saugkanal 20 for his part over the line 11 with the vaccum pump 10 stands in connection. On the other side the clutch 18 connected with a channel 21 is in the cover 14 of the Unterdruckbehälters 9, which leads to its interior 12. The clutch 18, which on the basis an example in Fig. 3 in the detail is represented, possesses two parts. A first part of 22 " of the clutch 18 is stationarily in the cooler arranged, i.e. it cannot be taken from this without disassembly. A second part of 23 of the clutch 18 is firmly arranged at the Unterdruckbehälter 9. The two parts of 22, 23 are in such a way out-arranged that they can to be simply interconnected and again from each other solved and in connected condition one essentially to gas density coupling between the interior 12 and the vaccum pump 10 form. The first part of 22 is arranged at the frame part 7 and exhibits a first valve with a valve body 25a and a valve seat 25b. The valve body 25a is pressed with suspension reading tables an arrangement 25c, in particular a feather/spring, against the valve seat 25b (broken represented in Fig. 3), with Kraft, which are able to hold the valve body 25a against the ambient pressure the valve seat 25b. In this way the first part of 22 of the clutch 18 is closed, if it does not cooperate with the second part of 23, i.e. if no Unterdruckbehälter 9 is assigned. The first valve 25a, 25b, 25c can be opened by attachment of the second part of 23 of the clutch 18 at the first part 22. For this an operating organ 27 is intended at the second part of 23, with which the valve body 25a is away pressed with connecting first and the second part of 22, 23 by the valve seat 25b. In the execution after Fig. this operating organ 27 is formed for 3 by a thorn, which rises up out of the delta 28 of the second part of 23 approximately outside. The thorn possesses a central channel 29a and lateral openings 29b at its point, in order to ensure a gas flow of second into the first part. The delta 28 of the second part of 23 of the clutch 18 is arranged at the boundary region 16 of the cover 14, so that it is well accessible. In the execution after Fig. it is 3 at the lower surface of the boundary region 16, so that it comes to be when inserting the Unterdruckbehälters 9 into the frame part 7 on the delta 30 of the first part of 22 of the clutch 18 directed upward. More generally said, the Unterdruckbehälter 9 into the frame part 7 can be inserted preferably in such a way that it is held at the boundary region 16 of the cover 14 by the frame part 7 and that the delta 30 of the first part of 22 of the clutch 18 comes to lie with the delta 28 of the second part of 33. At the second part of 23 of the clutch 18 a Rückschlagventi131 is arranged, which closes, if in the interior 12 of the Unterdruckbehälters 9 a lower pressure prevails than at the delta 28 of the second part of 23 of the clutch 18. The check valve 31 guarantees that the negative pressure in the interior will maintain 12 also after the withdrawal of the Unterdruckbehälters 9 from the cooler. In addition it prevents also the gas entrance into a coupled Unterdruckbehälter, if the negative pressure system of the refrigerator is defective. As from Fig. 1 evidently, is favourably in such a way out-arranged that frame part 7 that he is able to take up several Unterdruckbehälter 9. Accordingly it possesses several openings 8, which are adapted in their form to the respective Unterdruckbehältern 9. Not all Unterdruckbehälter 9 must possess the same form or size. Fig. a second execution of a Unterdruckbehälters 9 shows 4 in the form of a drawer, which either completely or at least partly out of the cooler can be pulled. For this it is held in a suitable drawer camp. It possesses a lower part 15 and a cover 14, which enclose the interior 12. The cover 14 is as previously mentioned, favourably so out-arranged, that it automatically opens when pulling the Unterdruckbehälters out 9 and/or when pushing the Unterdruckbehälters 9 in automatically closes. For this the cover 14 can e.g., as in Fig. 4 represented, connected by a horizontal drag axis 32 with the lower part 15 its and e.g. with spring action to be linked up in such a way that it comes up, as soon as the drawer is pulled out, if the interior 12 is aired out before by means of a suitable ventilation valve. Such a ventilation valve is exemplary in Fig. 2 represented, in form of a second valve with a valve body 34a, a valve seat 34b and a Federanordnung, whereby the latters in the execution after Fig. 2 by a perforated feather/spring diaphragm 34c one forms. The feather/spring diaphragm 34c presses the valve body 34a against the valve seat 34b, with Kraft, which are able to hold the valve body 34a against the ambient pressure the valve seat 34b. Further an operating organ 35 is intended, with which the user can force the valve body away 34a of the valve seat 34b, in order to ventilate so the interior 12. In the execution after Fig. the second part of 23 of the clutch 18 exemplarily at the lower part 14 is arranged 4, at its back (i.e. that the Benutzertüre of the cooler turned away side), so that when pushing in a contact with an appropriate first, at the rear wall of the store 2 can be manufactured automatically arranged first part of the clutch. Remarks: As in Fig. suggested, the Unterdruckbehälter 9 can exhibit 2 a water tank 36. As initially already mentions, this can be used to moisten the interior 12. It can be out-arranged e.g. as bowl at the wall or at the ground of the Unterdruckbehälters 9. That frame part 7 can by means of a suitable storage 38 (see Fig. 1) extendable in the cooler arranged its. In this case the line 11 is preferably in such a manner flexible, in order to follow a movement of the frame part 7 around at least 10 cm. By the withdrawable arrangement of the frame part 7 the Unterdruckbehälter 9 are better accessible. In the execution after Fig. 1 is arranged that frame part 7 horizontal and the Unterdruckbehälter 9 is accessible from above. Conceivably however also a vertical arrangement of the frame part and/or a horizontal accesibility of the Unterdruckbehälter are 9. For the execution after Fig. 4 it was mentioned that the cover can open 14 automatically when pulling the drawer out. Conceivable however also an arrangement, with which the cover 14 remains closed when taking the drawer out and from which Unterdruckbehälter 9 so the cooler can be taken, is similarly as during the execution after Fig. 1-3. If several Unterdruckbehälter 9 are intended, then can do all this directly or, as previously mentioned, differently out-arranged to be, and e.g. concerning dimensions, materials, transparency, cover, lower part, form and color differ. In particular they can be adapted the respective intended purpose: - the Design of a Unterdruckbehälters can be selected e.g. in such a way that it is suitable for direct serving on the Esstisch, and in particular that lower part 15 can be out-arranged as elegant dish, since the technical components are integrated in the cover 14. - the Unterdruckbehälter, or at least that lower part 15, can be temperature-steadily arranged, so that it is suitable for warming up/regenerating in the furnace or Steamer. - the Unterdruckbehälter, or at least that lower part 15, can be temperature steady also for still higher temperatures, so that it is suitable for warming up on the cool top platform (classical, induction, thermal line over hochebenen ground). The Unterdruckbehälter 9 know or two adjustable Datumsanzeigen 39 (see Fig. 2) to reading off a date exhibit, like e.g. the date of racking and/or expiration date. It can concern mechanical units (number wheels) or electronic units. The Unterdruckbehälter 9 can exhibit a pressure sensor 40 (see Fig. 2). It can concern an electronic sensor or a mechanical sensor. The pressure sensor contains favourably expenditure means 40a, which it to the user permit to read off the printing condition of the interior 12 directly from the Unterdruckbehälter 9. The expenditure means 40a can indicate the pressure continuously or gradually, also binary (negative pressure or no negative pressure). In particularly simple way this, as mentioned, can be made by a mechanical crack frog, i.e. the expenditure means 40a are formed by the diaphragm of the crack frog. Together with a pressure sensor the containers can also e.g. exhibit a gas sensor, which is able to e.g. recognize rot gases (CO2, methane) in the interior 12. They can exhibit also a temperature sensor, which measures the temperature of the interior 12. In the remark examples so far shown one of the parts of the clutch 18 is firmly in the cooler arranged and the other one at the Unterdruckbehälter 9, in such a manner that these provide a connection automatically with intended arranging of the Unterdruckbehälters 9. It is in addition, conceivable that the connection is provided in each case over a flexible hose. At the Unterdruckbehälter an input device can be intended, over which users the evacuation of the same can permit when inserting into the cooler or suppress. In the execution after Fig. 3 for this exemplarily a rotary switch 41 is intended, which affects and this in two different vertical positions bring can 42 the operating organ 27 over a spindle, whereby it operates the first valve 22 only in the lower position. This input device can be combined also with the mentioned Belüftungsventi134a, 34b, 34c, so that both functions with only one input device can be steered. The control 6 is favourably connected with a display unit 44 (see Fig. 1), in order to indicate to the user the status of the cooler. In particular the control can be so out-arranged 6 the fact that it recognizes a leakage in an attached Unterdruckbehälter 9 and this to the user over the display unit 44 indicates if necessary. For this there are different possibilities. In a simplest execution the control 6 with a suitable sensor can state that the vaccum pump 10 is able to achieve a given negative pressure in the negative pressure system, e.g. in the line 11, not - this is a reference on the fact that one of the attached Unterdruckbehälter is not close 9 or that the negative pressure system for another reason licks. As exemplary in Fig. 4 represented, also a pressure control can be arranged at the Unterdruckbehälter 9, which e.g. covers a variable valve 46 and which pressure in the interior regulates with attached vaccum pump 10 on a desired value, so that the pressure is adapted to respective application. Preferably the pressure control of a far unity partial device possesses 47, with which the desired value of the pressure (gradual or continuous) can be given. The desired value of the pressure can be varied favourably at least over 0.1 to 0,5 bar, so that the user can adapt it to relevant applications. For this the valve 46 can be e.g. subjected with Kraft of a feather/spring 48, whose Kraft can be varied over the rigging device 47, so that the valve 46 opens only if the pressure in the interior 12 exceeds the desired value. The pressure control after Fig. 4 can do also in the execution in accordance with Fig. 1-3 to be used. While in the available registration preferred remarks of the invention are descriptive, it is to be pointed out clearly that the invention is limited to these not and can in also different way within the range of the following requirements be implemented.
