Patent ID: 8334487

Claim:
An induction heating cooking device comprising: a top plate that is partially or entirely made of a material capable of transmitting infrared radiation, a cooking container being placed on the top plate; a heating coil that induction-heats the cooking container; an infrared sensor, provided under the top plate, that detects infrared radiation which is emitted from a bottom surface of the cooking container facing the heating coil and is passed through the top plate, and that outputs a detection signal based on the quantity of energy of the detected infrared radiation; and a heating control section that controls supply of electric power to the heating coil by flowing a high-frequency electric current through the heating coil based on temperature of the bottom surface of the cooking container which is detected by the detection signal; wherein the infrared sensor is configured to output the detection signal having output values increasing as the bottom-surface temperature increases when the temperature of the bottom surface of the cooking container is equal to or higher than a first predetermined temperature which is higher than 230 degrees C., and the infrared sensor is configured not to output the detection signal when the bottom-surface temperature is lower than the first predetermined temperature, and the heating control section reduces or stops the electric power supplied to the heating coil when the bottom-surface temperature of the cooking container detected by the infrared sensor is equal to or higher than a second predetermined temperature which is higher than the first predetermined temperature and is lower than an ignition temperature of cooking oil which is about 330 degrees C.
