Abstract
An induction heating cooker includes: a top plate on which a cooking container is placed; a temperature measuring device which has an infrared ray sensor operable to detect infrared rays radiated from the cooking container and a temperature converting unit operable to calculate a temperature of the cooking container from an output of the infrared ray sensor; a heating coil operable to receive a supply of a high frequency current and generate an induction magnetic field for heating the cooking container; and a heating control unit operable to control the high frequency current of the heating coil based on the temperature measured by the temperature measuring device, and control heating power to be supplied to the cooking container. The temperature measuring device further includes a temperature detecting unit operable to measure a temperature of the infrared ray sensor, and calculate the temperature of the cooking container from an output of the infrared ray sensor based on the temperature of the infrared ray sensor measured by the temperature detecting unit.
