<p><P>PROBLEM TO BE SOLVED: To provide an induction heating device in which an electric current flowing in a heating coil which heats a kettle by connecting resonant capacitors in parallel is controlled by a conduction controlling element and in which a spectrum of a radiating noise is dispersed and in which there is no large peak in a specific frequency. <P>SOLUTION: A pan 1 is housed in a rice cooker main body detachable and a bottom of the pan 1 is heated by a heating coil 2 through an induction heating and resonant capacitors 3 are connected in parallel with the heating coil 2 and circulation diodes are arranged in parallel with the conduction controlling element 5 to control a current flowing in the heating coil 2 and the conduction controlling element 5 is electrically conducted for a predetermined time Ton by a timer means 7. When a detected current value Iin of a current value detecting means 9 to detect a current value supplied to a direct current power source is Iin2 or more which is set up by a second current value setting means 12, a setting time Ton by the timer means 7 is increased/decreased periodically by a Ton changing means 13. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
