摘要

A protective device for induction heating apparatus is disclosed. The device includes an excitor supplied with operating voltage for induction-heating a heating element and a detecting device for detecting the state of the heating element. Means are provided for stopping the operating voltage to the excitor when the detecting device detects an abnormal state of the heating element and for applying the operating voltage to the excitor after a predetermined delay when an abnormal state of the heating element is not detected.
