Abstract

PURPOSE: To obtain suitable temperature control unit for use with the selector for power application to heater, by releasing the hold function with the signal caused with the operation of the temperature detection circuit when two heaters reach the maximum value within the temperature variable range.
CONSTITUTION: When the power switch 1 is closed and the self hold means operation switch 60 is pushed, the self-hold means is operative. Further, the heater for breast consisting of the heater 88, polyamide resin 90 and short circuit wire 89, and the heater for foot consisting of the heater 91, polyamide resin 93, and short circuit wire 92 are powered and increase to the maximum set temperature. Further, as the heater temperature increases, the temperature of the sensing layer 18 of the heat sensor contributing to the temperature detection consisting of the primary and secondary windings 16, 17 and heat sensing layer 18 increases and the impedance is decreased. Then, the self-hold is released with the signal caused by the operation of the temperature detection circuit formed with the differential amplifier, resistance bridge and temperature sensing circuit.
