Patent ID: 7102109

Claim:
An induction heating cooker comprising: a top plate having a first surface and a second surface, the first surface of the top plate being arranged to have a load pan placed over the first surface, the top plate being capable of transmitting infrared radiation; a heating coil for inductionally-heating the load pan; an inverter for supplying a high-frequency current to the heating coil; an infrared detector for detecting infrared radiation emitted from the load pan, the infrared detector being located under the second surface of the top plate; a first temperature detector for detecting a temperature of the load pan based on an output of the infrared detector; a heating controller operable to determine that the temperature of the load pan becomes stable if a condition that a change of the temperature detected by the first temperature detector is within a predetermined range for a predetermined period of time is satisfied, and to control a power output from the inverter based on a determination result; a first thermo-sensitive element for receiving heat from the top plate; and a second temperature detector for detecting a temperature of the load pan based on an output of the first thermo-sensitive element, wherein, when the temperature detected by the first temperature detector does not satisfy the condition, the heating controller determines that the temperature of the load pan becomes stable based on the temperature detected by the second temperature detector.
