<p><P>PROBLEM TO BE SOLVED: To provide a temperature detector for a cooker, detecting the temperature of a cooking container with reduced error to the utmost even when using an emissivity variable type cooking container as the cooking container. <P>SOLUTION: An infrared ray intensity detecting means 40 detects the infrared ray intensity about two wavelength regions K1 for measuring a first temperature, two wavelength regions K2 for measuring a second temperature, and a wavelength region K3 for determining the temperature. A temperature detecting means 50 determines the temperature of the cooking container based on the respective estimated temperature when a difference between a first estimated temperature obtained based on the ratio of infrared ray intensities of the two wavelength regions K1 for measuring the first temperature and a second estimated temperature obtained based on ratio of infrared ray intensities of two wavelength regions K2 for detecting the second temperature is within an allowable range, and when the difference between the first estimated temperature and the second estimated temperature is out of the allowable range, the temperature of the cooking container is determined based on the infrared ray intensity detected about the wavelength region K3 for determining the temperature. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
