Induction heating cooker including an infrared ray sensor and detecting whether there is a failure in the infrared ray sensor

摘要

An induction heating device according to the present invention includes an infrared ray sensor for detecting infrared rays radiated from a cooking container through a top plate, a light emitting device which is placed near the infrared ray sensor and emits light to the back surface of the top plate, and a heating control unit which controls a high-frequency current through a heating coil for controlling the heating of the cooking container. When the heating control unit has stopped the heating of the cooking container, and a predetermined time elapses at the heating-stopped state, the light emitting device is controlled to stop the light emission therefrom. This can improve durability of the light emitting device, which enables maintaining a function of clearly indicating a position at which the cooking container should be placed and a function of detecting failures in the infrared ray sensor, which are roles of the light emitting device.
