Abstract

Abstract Translated from Japanese (57)【要約】 【課題】 この発明は、誘導加熱装置の内部のCPUが 暴走した場合でも対処することができ、発火等の危険を 防止できる。 【解決手段】 この発明は、誘導加熱装置58aの内部 のCPU113が暴走し、IHオン信号を出力した場合 でも、本体の主制御部90からの温度制御に伴うIHオ ン信号により、高周波オン、オフ回路116へのIHオ ン信号の供給を遮断し、高周波オン、オフ回路116か らコイル105への高周波電流の供給が禁止されている ものである。 (57) [Summary] The present invention can cope with a runaway of a CPU inside an induction heating device, and can prevent danger such as ignition. SOLUTION: The present invention is characterized in that even when a CPU 113 inside an induction heating device 58a runs out of control and outputs an IH ON signal, a high frequency ON / OFF is performed by an IH ON signal accompanying a temperature control from a main control unit 90 of a main body. The supply of the IH on signal to the circuit 116 is interrupted, and the supply of the high frequency current from the high frequency on / off circuit 116 to the coil 105 is prohibited.
