HEATING COOKER

PROBLEM TO BE SOLVED: To provide a heating cooker measuring temperature of a bottom face of a pot with good precision, so as to have an excellent cooking property. SOLUTION: The heating cooker is composed of: a heating means 13 heating the pot 11 put on a top plate 10; a temperature calculation means 24 calculating the temperature of the bottom face of the pot 11 from the output of an infrared-ray sensor 14 detecting the strength of infrared-ray irradiated from the bottom face of the pot; a light emitting means 19 making near-infrared-ray incident from an end face of the top plate 10; a radiation area 21 irradiating the near-infrared-ray arranged in a heating area 20 of the top plate 10; an irradiation rate conversion means 23 converting the radiation rate of the bottom face of the pot 11 depending on the output of a reflection sensor 22 detecting the strength of the reflection from the bottom face of the pot 11, arranged at an end face facing the light emitting means 19 of the top plate 10; and a control means 25 controlling the heating means 13 according to the heat defined as an output of the temperature calculation means 24. The temperature calculation means 24 is made to correct the temperature calculated from the output of the infrared-ray sensor 14 depending on the converted radiation rate. COPYRIGHT: (C)2006,JPO&NCIPI
