  The temperature setting device 28 has an operation unit (not shown) using, for example, a potentiometer. The operation unit is operated by a resting person so that the temperature is maintained by the heat-retaining Peltier element 22 and the cooling Peltier element 24. The temperature of the upper portion 18 of the bed main body 12 to be cooled is set in the driving device 26.

  A plurality (three in the present embodiment) of bed temperature sensors 30 as temperature sensors are connected to the temperature setting device 28. These bed temperature sensors 30 are provided, for example, on the lower surface 20A of the heat conductive sheet 20 described above. In the present embodiment, these bed temperature sensors 30 are spaced apart from each other along a center line CL along the longitudinal direction of the bed main body 12, and the bed temperature sensor 30 is located with respect to the center line CL. As described above, one pair is provided for each pair of heat retaining Peltier elements 22 (or a pair of cooling Peltier elements 24). These bed temperature sensors 30 detect the temperature of the upper portion 18 of the bed body 12 by detecting the temperature of the heat conductive sheet 20.

  In addition, an ambient temperature sensor 32 as a temperature sensor is connected to the temperature setting device 28. The ambient temperature sensor 32 detects the temperature around the bed body 12 (for example, the temperature in the room when the heat-retaining and cooling bed 10 is installed indoors).

  The temperature setting device 28 is based on not only the operation result of the operation unit (not shown) of the temperature setting device 28 but also the detection results of the bed temperature sensor 30 and the ambient temperature sensor 32, and the heat retaining Peltier element 22 and the cooling Peltier element. The temperature of the upper part 18 of the bed main body 12 to be kept warm and cooled by the 24 is set in the driving device 26.

When a non-illustrated operation section of the temperature setting device 28 of the heat insulation cooling bed 10 is operated by a resting person, the set temperature information (the operation result of the above operating section) of the upper part 18 of the bed main body 12 desired by the resting person is set as the temperature. Input to device 28. At this time, both the detection result of the bed temperature sensor 30 and the detection result of the ambient temperature sensor 32 are input to the temperature setting device 28, and the operation result of the operation unit, the detection result of the bed temperature sensor 30, and the ambient temperature Based on the detection result of the sensor 32, the temperature of the upper portion 18 of the bed body 12 that is kept warm by the heat-retaining Peltier element 22 (or the temperature of the upper portion 18 of the bed body 12 that is cooled by the cooling Peltier element 24) is the temperature. The setting device 28 sets the driving device 26.

  Here, when the temperature set in the driving device 26 by the temperature setting device 28 is higher than the temperature of the upper portion 18 of the bed main body 12 (for example, corresponding to a case where a resting person feels cold), the driving device. The current is applied to each of the heat retaining Peltier elements 22 by 26, and each of the heat retaining Peltier elements 22 is driven. For this reason, the heat conductive sheet 20 is heated by the heat insulating Peltier element 22. As a result, the upper portion 18 of the bed body 12 is kept warm. Accordingly, the body of the resting person lying on the bed body 12 is warmed. Thereby, the resting person can rest comfortably without feeling cold.

  On the other hand, when the temperature set in the driving device 26 by the temperature setting device 28 is lower than the temperature of the upper portion 18 of the bed main body 12 (for example, corresponding to a case where a resting person feels hot), the driving device The current is applied to each cooling Peltier element 24 by 26, and each cooling Peltier element 24 is driven. For this reason, the heat conductive sheet 20 is cooled by the cooling Peltier element 24. As a result, the upper part 18 of the bed main body 12 is cooled.

For this reason, the temperature of the upper part 18 of the bed main body 12 is adjusted, for example to the temperature of a resting person. Therefore, the resting person can rest more comfortably.

  Further, since the temperature of the upper part 18 of the bed main body 12 is detected by the bed temperature sensor 30 in the heat insulating cooling bed 10, the bed main body adjusted by the heat insulating Peltier element 22 and the cooling Peltier element 24 as described above. The temperature of the twelve upper portions 18 is repeatedly set to the driving device 26 by the temperature setting device 28 based on the detection result of the bed temperature sensor 30. At this time, the temperature around the bed body 12 is also detected by the ambient temperature sensor 32, so the temperature setting device 28 sets the temperature setting of the upper portion 18 of the bed body 12 as well as the detection result of the bed temperature sensor 30. This is also performed based on the detection result of the ambient temperature sensor 32. As a result, the temperature of the upper portion 18 of the bed main body 12 is repeatedly adjusted so as to be, for example, a temperature desired by a resting person. Therefore, the rester can rest even more comfortably.

  Further, the bed temperature sensor 30 corresponds to a pair of heat retaining Peltier elements 22 (or a pair of cooling Peltier elements 24) arranged as described above with respect to the center line CL along the longitudinal direction of the bed main body 12. One is arranged. For this reason, the temperature in the vicinity of the pair of heat retaining Peltier elements 22 (or the pair of cooling Peltier elements 24) in the heat conductive sheet 20, and thus the pair of heat retaining Peltier elements 22 ( Alternatively, the temperature in the vicinity of the pair of cooling Peltier elements 24) can be detected with high accuracy.

However, the present invention is replaced with the upper portion 18 of the bed main body 12. Either one of the temperature and the temperature around the bed main body 12 may be detected. Further, according to the present invention, the bed temperature sensor 30 and the ambient temperature sensor 32 are omitted, and the heat retaining Peltier element 22 and the cooling Peltier element 24 are driven based on the operation result of the operation unit (not shown) of the temperature setting device 28. It is good also as a structure driven by 26.

  Further, in the present embodiment, either one of the heat retaining Peltier element 22 and the cooling Peltier element 24 is driven by the driving device 26, but the present invention is replaced by, for example, the bed main body 12 The cooling Peltier element 24 and the cooling Peltier element 24 near the head of the resting person lying on the upper portion 18 and the warming Peltier element 22 near the leg of the resting person are driven. The Peltier element 24 may be combined and driven at the same time.

  In the present embodiment, all of the heat retaining Peltier elements 22 are driven, or all the cooling Peltier elements 24 are driven. However, the present invention is replaced with a part of the heat retaining Peltier elements 22. The Peltier element 22 may be driven, or a part of the cooling Peltier element 24 may be driven. For example, the cooling Peltier element 24 near the head of a resting person lying on the upper portion 18 of the bed body 12. Only the warming Peltier element 22 near the waist of the resting person or only the warming Peltier element 22 near the waist and the leg of the resting person may be driven. .
