Abstract:
1. An induction heating cooker comprising: a top plate on which a cooking container is placed; a temperature measuring device which includes an infrared ray sensor operable to detect infrared rays radiated from the cooking container through the top plate 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 generate an induction magnetic field for heating the cooking container by receiving a supply of a high frequency current; and a heating control unit operable to control power for heating the cooking container by controlling the high frequency current of the heating coil based on the temperature calculated by the temperature measuring device, wherein the temperature measuring device further includes a temperature detecting unit operable to measure a temperature of the infrared ray sensor, and calculates 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, and wherein the temperature measuring device further includes:
