Abstract

PURPOSE: To enable a desired heating in reference to a sensed temperature by a method wherein noise generated by infrared rays radiated from the floating materials in the heating chamber is prevented from being mixed with an output signal produced from the infrared ray sensing unit and a temperature of the foodstuff may be detected correctly.
CONSTITUTION: A correcting temperature sensor 15 for producing the same signal as the noise voltage VN in response to a temperature in the second duct 10 is arranged in the second duct 10 near the infrared ray sensor unit 14 installed in the heating chamber 2, and at the same time the subtractor 17 and microcomputer 19 are also arranged. When a finishing temperature of the foodstuff 3 is set by an operation panel 16 and a hot air heating operation is initiated, the computer 19 performs a subtraction of the output signal of the correction temperature sensor 15 from the output signal of the infrared ray sensor 14, the noise voltage VN is removed and a temperature of the foodstuff 3 may be sensed accurately.
