发明名称 DIELECTRIC HEAT COOKING DEVICE
摘要 The present invention provides an induction heating cooker, which is structured to cut off visible light being incident upon an infrared sensor, yet being capable of more accurately sensing any abnormality of the infrared sensor before heating is started. To this end, the induction heating cooker includes: a sensor failure sensing-purpose light emitting portion 7 that emits visible light for sensing any failure of an infrared sensor 5; a visible light cutting filter 6 provided on a surface of a printed circuit board 5 holding the infrared sensor 5 so as to cover the field of view of the infrared sensor 4; and a control unit 11 that limits the output of an inverter circuit 10 supplying a high-frequency current to a heating coil 3 when the output of the infrared sensor 5 is equal to or less than a threshold value in a situation where the sensor failure sensing-purpose light emitting portion 7 is lit up. The infrared sensor 5 receives the visible light from the sensor failure sensing-purpose light emitting portion 7 to irradiate inside the visible light cutting filter 6.
