DETAILED DESCRIPTION

(5) FIG. 1 shows an embodiment of an invention-specific device 2 for regulating the temperature of at least one object 6 (see FIG. 2). The device 2 for regulating the temperature of the at least one object 6 comprises a thermoelectric element 4, which is configured as a Peltier element 4. As an additional component, device 2 comprises a processor unit 12, which is coupled to thermoelectric element 4. Processor unit 12 is provided to control and/or monitor thermoelectric element 4.

(6) Processor unit 12 is coupled with sensor 8, as can be seen by means of the connection depicted by reference to number 16. Additionally, device 2 comprises a sensor device 20. Sensor device 20 has at least one sensor 8 for detection of a de facto temperature in the area of thermoelectric element 4. Ideally, as sensor 8 Negative Temperature Coefficient sensor, called NTC sensor 8 for short, is used. In this embodiment, sensor 8 is situated on a wide lateral surface 10 of thermoelectric element 4. Additionally, at least one more sensor 14 is provided for detection of a de facto temperature in the area of processor unit 12. Additional sensor 14 is configured as a component of processor unit 12. Additional sensor 14 can especially be a negative temperature coefficient sensor 14, which is integrated into processor unit 12. Processor unit 12 is in connection with sensor unit 20. Likewise, a connection 16 is provided for it. Thermoelectric element 4, processor unit 12 and sensor device 20 are enclosed by a housing 18 or accommodated by a housing 18.

Processor unit 12 is configured to check thermoelectric element 4 for a Seebeck voltage. If a Seebeck voltage is present, processor unit 12 halts a comparison of the detected de facto temperatures; if no Seebeck voltage is present, processor unit 12 can carry out a comparison.

(7) FIG. 2 shows another embodiment of an invention-specific device 2 for regulating the temperature of at least one object 6. Thermoelectric element 4 of device 2 is provided here to emit heating and/or cooling energy to a container for drinks 24 that can be thermally regulated. Drink container 24 capable of thermal regulation has an acceptor unit 26 in which an object 6, for example in the form of a drink holder 6, can be admitted for temperature regulation. Thermoelectric element 4 is coupled with acceptor unit 26. A wide lateral surface 10 of thermoelectric element 4, which adjoins acceptor unit 26, can be designated as the effective side 10 of thermoelectric element 4, since on effective side 10, heating and/or cooling energy is emitted to particular object 6. An additional wide lateral surface 10 of thermoelectric element 4, to which a means for cooling 28 of thermoelectric element 4 in the form of a cooling body 28 is coupled, can be designated as the waste heat side 10 of thermoelectric element 4. In addition, device 2 has a sensor device 20, which comprises a sensor 8 for detection of a de facto temperature trending in the area of thermoelectric element 4 and an additional sensor 14 configured as a component of processor unit 12 for detection of a de facto temperature in the area of processor 12. Sensor 8 is situated on the effective side 10 of thermoelectric element 4, to additionally be able to detect the de facto temperature in the area of object 6. Processor unit 12 is coupled with thermoelectric element 4 and is in connection with sensor device 20, as is shown by reference symbol 16. Thermoelectric element 4, processor unit 12 and sensor device 20 are situated in a common housing 18. Also, the means 28 for cooling can be in housing 18. Processor unit 12 is provided for comparison of de facto temperatures detected by sensors 8 and 14, which are configured in the area of thermoelectric element 4 and processor unit 12. Using processor unit 12, through the comparison of de facto temperatures, an assessment on the functional capability of sensor device 20 can be derived.

(8) FIG. 3 discloses an additional embodiment of an invention-specific device 2 for regulating the temperature of at least one object 6. In this, thermoelectric element 4 of device 2 is provided for regulating the temperature of a storage battery 6. Thermoelectric element 4 with the effective side 10 adjoins storage battery 6, by the waste heat side 10, thermoelectric element 4 is coupled with a means 28 for cooling, for example in the form of a coolant circuit 28. For regulating and/or monitoring of thermoelectric element 4, device 2 has processor unit 12, which is coupled with thermoelectric element 4. Device 2 additionally has a sensor device 20, which comprises a sensor 8 for detecting a de facto temperature trending in the area of thermoelectric element 4, as well as an additional sensor 14 configured as a component of processor unit 12, for detection of a de facto temperature trending in the area of processor unit 12. Sensor 8 is situated in the area of the effective side 10 of thermoelectric element 4. Processor unit 12 is connected with sensor unit 20. Thermoelectric element 4, processor unit 12 and sensor device 20 are situated in a common housing 18. Also, the means 28 for cooling is in housing 18. Additionally, by means of processor unit 12, it is possible to compare the de facto temperatures detected by sensors 8 and 14, which are configured in the area of thermoelectric element 4 and processor unit 12, Using processor unit 12, through the comparison, an assessment on the functional capability of sensor device 20 can be derived.

(9) FIG. 4 shows a flow chart of an embodiment of an invention-specific method for checking the functional capability of a sensor device 20 consisting of at least two sensors 8, 14. In a first step 101 of the method, processor unit 12 is started or placed in operation, and immediately following a de facto temperature is detected (step 102) of a sensor 14 configured as a component of processor unit 12. Doing a readout of the one additional sensor 14 immediately after startup of processor unit 12 yields an advantage in that the particular de facto temperature detected via sensor 14 is not influenced by intrinsic warming of processor unit 12, or not substantially.

(10) In the following step 103, a Seebeck voltage of thermoelectric element 4 is checked. The check can be done via processing unit 12. If no Seebeck voltage of thermoelectric element 4 forms, or if a Seebeck voltage is determined with a value of 0 volts or at least approximately 0 volts, the procedure can be continued (step 104).

(11) With this in step (105a), sensor 8 for detection of the de facto temperature trending in the area of thermoelectric element 4 is read out using processor unit 12. Ideally, sensor 8 is read out during or immediately after starting thermoelectric element 4, to avoid influencing the de facto temperature which is trending, in the area of thermoelectric element 4, due to intrinsic heating of thermoelectric element 4 during operation and/or through a release of heat of processor unit 12. If, according to step 104, the Seebeck voltage of thermoelectric element 4 yields a value other than 0 volts or at least approximately 0 volts, it is not possible to check sensor device 20 for functional capability (step 105b).

(12) After readout of sensor 8 of thermoelectric element 4, as per step 106 a comparison is made of the de facto temperature detected by sensor 8, which is trending in the area of thermoelectric element 4, and the de facto temperature detected by additional sensor 14, which is trending in the area of processor unit 12. Hereupon an assessment is made of the functional capability of sensor device 20 (steps 107a and 107b). If the de facto temperatures detected by sensors 8 and 14 manifest differing values, then as per step 108b, sensor device 20 is found to be non-functional. Consequently, one of sensors 8 and 14 is not functioning in fault-free fashion. If, in a defined range, the de facto temperatures detected by sensors 8 and 14 have a nearly identical value when compared in step 106, then it can be concluded that sensors 8 and 14 of sensor device 20 are functionally capable or fault-free. Ideally, the de facto temperatures trending in the area of thermoelectric element 4 and of processor element 12 can be compared at repeated fixed intervals (step 109).
