<p><P>PROBLEM TO BE SOLVED: To provide an induction heating cooking device capable of properly controlling heating power by preventing excessive heating by monitoring deformation of a pan. <P>SOLUTION: This cooking device is equipped with a high frequency power supply circuit to supply high frequency power to a heating coil, an infrared sensor module provided in the lower part of a gap between an inner peripheral coil and an outer peripheral coil, a control circuit to control the high frequency power supply circuit, and a display part to display an energized state. The infrared sensor module is formed by adjacently disposing a thermal infrared detection circuit, and a reflectance detecting circuit including an infrared emitting element to irradiate infrared ray toward a pan, and an infrared receiving element to receive infrared ray reflected by the pan, and the control circuit performs normal heating when the output voltage of the infrared ray receiving element is higher than a threshold value, and stops heating when the output voltage of the infrared receiving element is not higher than the threshold value. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
