Refrigerator with a sensor in the store.

Area of the invention the invention concerns a refrigerator with a store for the admission of cooling property and with at least one sensor. Background around the temperature of a refrigerator to regulate, is normally used a temperature sensor. This is arranged at the store of the refrigerator and measures its temperature. It participates important that a temperature is measured, which corresponds as exactly as possible to the temperature in the relevant part of the store. Representation of the invention it places itself therefore the task to make a refrigerator available of the kind initially specified with which it is possible to measure a parameter inside the store with good accuracy. This task is solved from the refrigerator in accordance with requirement 1. At least one sensor is arranged accordingly and at least with the sensor of connected transmitters in the store of the equipment. Outside of the store is a receiver. The signal of the sensor can be conveyed wirelessly by the transmitter to the receiver. In this way it becomes possible to measure a parameter inside the store, i.e. at the place, which is from interest, what permits a precise measurement. Besides can be done without a breaking through of the store wall, which simplifies the isolation of the store and the cleaning of the same. The sensor is preferably a temperature, Feuchteoder gas sensor, or a combination of several such sensor types. In case of a gas sensor the sensor is preferably in such a way out-arranged that it can measure typical rot gases, which refer to a decay of the stored food. In another preferential execution the sensor is a pressure sensor, in particular for the monitoring of vakuumiertem cooling property. The receiver is preferably in such a way out-arranged that with it a first signal can be sent to the transmitter, with whom the transmitter and the sensor be operated can, i.e. from which the transmitter and the sensor the energy to their enterprise to refer. Transmitters and sensor need no own energy source in this case thus. The sensor can form a part of an automatic control loop of the refrigerator, with which by the sensor of measured parameters, the temperature will be e.g. held, to a given value. 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 a cut by a refrigerator and a block diagram of a possible execution of the transmitter and the receiver. Ways to the execution of the invention in Fig. 1 is described a remark example of the invention. The refrigerator possesses a store 1, in which editions 2, e.g. in the form of lattices or glass plates, for the admission of the property which can be cooled are arranged e.g. The edition 2 forms an employment entnehmbaren from the store. At the front the store 1 by a “Füre 3 is locked, on the remaining sides the store walls 4 of insulating wall elements is formed. In the range the “Füre 3 opposite rear wall of the store 1 is arranged a refrigerator 5, with which the store 1 is cooled. In the available example three sensors 6-8 are arranged in the store, whereby however also only or two sensors or more than three sensors can be planned. A first sensor 6 is exemplarily in the range of the cover of the store 1 or at the store wall 4 intended. It can be fastened e.g. with a mounting plate solvable to the cover or wall or connected firmly with this. A second sensor 7 is exemplarily fastened to one of the editions 2 for the admission of the property which can be cooled. A third sensor 8 is in a chamber 10. this chamber 10 is firmly or entnehmbar in the store 1 arranged and from the store 1 over chamber walls partly or completely separated, so that in the chamber 10 will keep a climate different of the remainder of the store upright can, e.g. with different temperature and/or air humidity. The chamber 10 can be e.g. at least partly formed by an employment 11 removable from the store 1, at which the sensor 8 is arranged. In this way the sensor 8 can be taken from the equipment together with the employment 11. The employment 11 can e.g. form optional accessories of the equipment. In a preferential execution the employment 11 is a drawer. The sensors 6, 7, 8 can as optional components of the refrigerator intended, which can be bought to go with by the user if necessary. All sensors 6, 7, 8 are assigned to a transmitter 14 in each case. These transmitters are in Fig. 1 not separately represented, but only in Fig. 2. In the execution after Fig. 1 is favourably integral connected to each transmitter 14 with its respective sensor 6, 7, 8. Outside of the store 1 a receiver 15 is arranged. In the execution after Fig. 1 is arranged the receiver underneath the store 1, it can however also up or laterally the store be. The transmitters 14 are out-arranged in addition, the signal of their respective sensor 6, 7, to send 8 wirelessly to the receiver 15. The receiver 15 is connected with a control 16 of the refrigerator, which steers the components of the equipment. A preferential structure of the receiver 15 as well as the unit from transmitter 14 and sensor 6, 7, 8 is in Fig. 2 represented. In this execution the receiver and the temperature sensor are 6, 7, 8 purely in each case passive components without own current supply, which refer the energy of the transmitter 15, necessary for the enterprise. The receiver 15 possesses Sendeund receipt coil 18, over which he sends a first signal. This signal will receive 14 consisting in the transmitter from a resonant circuit of Sendeund receipt coil 19 and a capacity. With a diode 21 in such a way received signal is smoothed parallelly and in a condenser 22, so that it can serve 23 as supply voltage for a micro CONTROLLER and the sensor 6, 7 and/or 8. If the micro CONTROLLER 23 receives a signal, then it produces a sequential digital output signal dependent on the parameter value, which was measured by the sensor 6, 7, 8, with which it switches a transistor off 25, which is arranged parallel to the condenser, einund, whereby it modulates the quality of the resonant circuit formed by the condenser 20 and the coil 19. Dependent on this quality the resonant circuit 19, 20 reflects a larger or smaller part of the received signal, so that Sendeund receipt coil 18 of the receiver 15 detects a reflected signal, which is amplitude-modulated with the serial signal at the gate of the transistor 25. With an amplifier and a demodulator 26 this signal in the receiver 15 can be demodulated, so that the receiver 15 can derive the sensor signal from it. In other words the transmitter 14 is thus out-arranged in addition, the first signal, which it receives from the receiver 15, dependent on the parameter, which is measured by the sensor 6, 7, 8 to modulate and send back to the receiver 15. Fig shows. 2 only a possible arrangement of the transmitter 14 and the receiver 15. Further circuit technologies of this kind are well-known the specialist from the area of the RFID tags. The sensors 6, 7, 8 can resemble or different parameters to measure. Parameters, which are applicable, e.g. are: - Temperature: In an important application at least one of the sensors 6, 7, 8 is out-arranged to measure a temperature. It can do itself e.g. around a temperature 1 in the store 1 even (sensors 6, 7 in the execution after Fig. 1) or in the chamber 10 (sensor 8) act. - Humidity: The humidity in the refrigerator is an important parameter, which e.g. affects the ice formation, as well as an influence on the shelf-life of the cooling property has. The refrigerator can be out-arranged e.g. to indicate to the user a warning if the humidity measured of one of the sensors 6, 7, 8 is too high in the refrigerator. - Gas composition: The sensor can be also a gas sensor. A sensor in this connection, which can recognize at least one gas, is particularly favourable, which is set free with a Fäulnisprozess. For this purpose at least one of the sensors can be in such a way out-arranged that he can detect CH4, H2S, NH3, H2 and/or CO2. If the appropriate gas concentration is too high, for example again a warning can be indicated to the user. - Pressure: The sensor can be also a pressure sensor. In a preferential application such a pressure sensor can be arranged e.g. at the packing of food stored in the refrigerator and be measured the pressure within the packing. It can concern in particular around a vakuumiertes product, i.e. a product, which is stored in its packing on vacuum conditions. A rise of the pressure can refer in this case a leakage in the packing or to a decomposition of the product. An automatic control loop is intended favourably in the refrigerator, which is out-arranged to hold the parameter measured by at least one of the sensors to a given value. For sensor 6 of Fig. 1 can this automatic control loop e.g. from the sensor 6, which exists control 16 and the refrigerator 5, if sensor 6 is a temperature sensor and the control 16 is out-arranged in addition, to activate or deactivate dependent on the signal of the sensor 6 the refrigerator 5. In this way the store temperature can be kept constant. In case of sensor 8 can, if sensor 8 temperature sensor is, which can be affected automatic control loop from the sensor 8, which exists control 16 and a separately controllable cooling section 28, e.g. an Peltier element, with which the temperature in the chamber 10 purposefully. In this case the automatic control loop can be out-arranged to hold the temperature in the chamber 10 to a given value which differs from the being supposed mdu advice original measured value im übrigen store 1. For vegetables this value can be e.g. with 0.5 to 2°C, for meat about -1 to 1°C. Preferably the transmitter 14 an identification code is stored in everyone. The transmitter 14 is out-arranged to send additionally to the parameter signal the identification code to the receiver 15 to send or a signal only if it receives an identification code specific to it from the receiver 15 in the first signal. The identification code contains at least one of the following information: - Kind the transmitter 14 of assigned sensor: In this case differs the identification code for sensors, which measure different physical parameters. E.G. the identification code of a temperature sensor differs in principle from that one of a dampness sensor. - Place the transmitter 14 of assigned sensor: In this case differs the identification code for sensors, which are arranged in different places in the store. Thus the sensor 8 in the chamber 10 carries another identification code than the sensor 7 at the edition 2 or the sensor 6 at the cover of the store 1. With this identification code the control 16 can determine, from which for a sensor a signal became to receive and/or where this sensor is. This permits it to configure the refrigerator by bringing in and/or removing individual sensors purposefully and simply and besides the control 16 can differentiate automatically between several sensors. In the above examples the transmitter 14 is out-arranged as purely passive construction unit, which refers its energy of the first signal of the receiver 15. Conceivably it is however also to out-arrange the transmitter 14 as active construction unit which has its own energy source, e.g. in form of a battery. 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.
