<p><P>PROBLEM TO BE SOLVED: To achieve a safe and user friendly induction heating device accurately detecting high temperature state of an object to be heated in various conditions. <P>SOLUTION: A control means 8 controls heating output of a high frequency inverter 1 so as to restrain or stop it in compliance with temporal change of control amount, and made to change a value for determining control amount of heating output in compliance with conditions. Thereby, heating output of the high frequency inverter 1 is restrained or stopped by accurately detecting the high temperature state of the object to be heated 6, by eliminating various difference of conditions such as the kind and state of the object to be heated 6, the temperature of a top plate, switching element or the like constituting the device, or change of preset heating power, and the safe and user friendly induction heating device can be realized. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
