PURPOSE:To permit to keep a main body temperature at a suitable temperature in accordance with a room temperature immediately after loading and change the same temperature to a predetermined temperature in a short time in case an user has set a temperature at a desired temperature by a method wherein the loading or unloading of a human body is detected by the change of phisical quantity of a human body detecting means, the temperature of the human body is controlled in accordance with the temperature setting of the user in case of loading and the temperature of the main body is controlled in accordance with the room temperature in case of unloading. CONSTITUTION:In case loading of a human body, the resistance of a pressurized conductive element is decreased, the input voltage of a comparator 11 becomes V28<=V29, High signal is outputted in the output 30 and the input voltage V of the comparator 20 becomes a value in which the D.C. voltage V is devided by resistance 17, 18 and valiable resistance 19. In case unloading of the human body, the pressurized conductive element is not applied with a pressure, the resistance value is increased to V28>V29, the Low signal is outputted in the output 30 of the comparator 11 and a current flows through the resistances 17, 42, room temperature sensor 41 and transistor 40. The input voltage of the comparator 20 is set at a High level in case the room temperature is low and at a Low level in case the room temperature is high. |
