<p><P>PROBLEM TO BE SOLVED: To provide a heating cooker which precisely detects the temperature of an article to be heated to perform an appropriate heating operation. <P>SOLUTION: This heating cooker includes: an infrared temperature detector 18 that is disposed above a top plate 12 on which the article 14 to be heated is placed and detects the temperature of the article 14 to be heated based on the dose of infrared radiation emitted from the article 14 to be heated; and a controller 22 that controls a driver 17 based on the temperature of the article 14 to be heated, detected by the infrared temperature detector 18, to control the heating operation of a heating portion 16, wherein the infrared temperature detector 18 detects the temperatures of a plurality of points in a region to be detected such as the side surface of the article 14 to be heated on the top plate 12, a boundary between the article 14 to be heated and the top plate 12, and the top plate 12, determines whether the surface state of the article 14 to be heated is a mirror or non-mirror surface based on the results of the detected temperatures, and then corrects the temperature of a predetermined point among the temperatures of the plurality of points based on a preset emissivity depending on the result of determination to set corrected temperature as the temperature of the article 14 to be heated. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
