Abstract

PURPOSE:To achieve a pleasent temperature control without the temperature difference of a body to be heated due to high or low ambient temperature, by using an NTC thermister as an output resistor of emitter follower stage. CONSTITUTION:An NTC thermister RTH is used as an output resistor of an emittr follower stage 4' inserted between a signal detecting stage 3 and a switching circuit stage 5. Thus, if a room temperature is high, an actual set temperature is lower than the set temperature, and if a room temperature is low, the actual set temperature is higher than the set temperature, allowing to achieve the temperature control according to the room temperature. Thus, without complicated circuit constitution, the temperature difference of a body to be heated due to high or low ambient temperature can be avoided for pleasant temperature control.
