<p><P>PROBLEM TO BE SOLVED: To enable to control accurately temperature of boiling detection or the like of a load pan when water is boiled in an induction heating cooker. <P>SOLUTION: This cooker is provided with a first boiling detection means 7 which is to detect boiling corresponding to the output of a first temperature detection means 6 to detect bottom face temperature of the load pan 1 based on the output of an infrared ray detection element 5, put underneath a top plate 2, to detect the infrared ray emitted from the bottom face of the load pan 1, and a second boiling detection means 11 to detect boiling corresponding to the output of a second temperature detection means 10 to detect temperature of the load pan 1 by a thermister 9 to detect temperature of the lower face of the top plate 2. By controlling a heating control means 8 so that electric power supplied to a heating coil 3 is suppressed or stopped corresponding to either of outputs of the first boiling detection means and the second boiling detection means, the temperature control of the boiling detection of the load pan 1 or the like can be carried out accurately and malfunction of the infrared ray detection element due to external disturbance light can be prevented. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
