<p><P>PROBLEM TO BE SOLVED: To provide a heating cooker capable of detecting the accurate temperature of a heated object even if the amount of infrared rays detected by an infrared sensor varies due to noise or if the heated object with the curved-up bottom is used. <P>SOLUTION: The heating cooker includes first and second thermistors 4a, 4b detecting the temperature of the heated object 21 induction-heated by a heating coil 3, in different positions through a top plate 2; the infrared sensor 6 detecting the amount of infrared rays radiated from the heated object 21 induction-heated by the heating coil 3; and a control part 12 setting the emissivity of the heated object 21 from the higher temperature of the detected temperatures of the first and second thermistors 4a, 4b and the amount of infrared rays detected by the infrared sensor 6, and computing the temperature of the heated object 21 from the emissivity and the amount of infrared rays detected by the infrared sensor 6. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
