<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 kettle 1 is housed in a rice cooker main body detachable and a bottom of the kettle 1 is induction-heated by a heating coil 2 and an electric conduction controlling element 5 to control a current flowing in the heating coil 2 is electrically conducted for a predetermined time Ton by a first timer means 7. An elapsed time T from a start of induction heating is measured by a second timer means 12 and the elapsed time T by the second timer means is set up by a timer time setting means. A Ton changing means increase/decrease a setting time Ton of the first timer means 7 periodically when a measured time of the second timer means 12 exceeds a time T set up by the timer time setting means 13. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
