<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: a top plate 12 on which the article 14 to be heated is placed; a heating portion that is disposed below the top plate 12 and heats the article 14 to be heated; a driver 17 that drives the heating portion; an infrared temperature detector 18 that is disposed above the top plate 12 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 the driver 17 based on the temperature of the article 14 to be heated, which is detected by the infrared temperature detector 18, to control the heating operation of the heating portion, 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, determines and the top plate 12, determines the emissivity of the article 14 to be heated depending on a temperature difference between he maximum temperature and the detected temperature of a predetermined point among the temperatures of the plurality of points; and then corrects the temperature of the predetermined point based on the emissivity to set the corrected temperature as the temperature of the article 14 to be heated. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
