<p>An induction heating device includes a top plate arranged to have an object placed thereon, a heating coil receiving a high-frequency current to inductively heat the object, an infrared ray sensor for outputting a signal in accordance with energy of received infrared ray, a temperature detector for detecting a temperature of the object based on the signal output from the infrared ray sensor, a heating controller for controlling the high-frequency current supplied to the heating coil based on the detected temperature, and a failure determining unit for determining whether the infrared ray sensor has a failure or not. This induction heating device can detect the failure of the infrared ray sensor, and thus stops or suppresses the heating upon detecting the failure of the infrared ray sensor.</p> |
