Abstract

PURPOSE: To improve the safety and reliability of a heating apparatus by supplying power to the high-temperature holding circuit of an electric apparatus only when a high-temperature holding switch is turned on without providing any dedicated circuit power source to the holding circuit, and by automatically releasing it from being fixed at the highest temperature.
CONSTITUTION: A temperature control circuit A rectifies an AC voltage across an AC power source 1 and a power control element 3 is connected in series to the AC power source 1 via a heater 4. The temperature of this heater 4 is detected by a temperature detecting circuit B via a temperature sensor 6 and its temerature detection signal and a signal from a temperature setting circuit C are compared with each othr by a comparator 20. The output of the comparator 20 controls a triggering circuit D, whose output controls the element 3. A zero-cross pulse generating circuit E generates a zero-cross pulse when the voltage of the AC power source 1 is 0V, and this pulse controls a high-temperature holding circuit F. With a high-temperature holding switch 35 on, its power source is supplied to the circuit F, thus improving the safety and reliability of a heating apparatus.
