<p><P>PROBLEM TO BE SOLVED: To provide an induction heating cooker which can reduce generation of interference sound regardless of the drive frequency of a heating coil. <P>SOLUTION: The induction heating cooker comprises a top plate 2 on which a pot is mounted, a plurality of heating coils 3, 7 provided under the top plate 2 and heating pots 6, 10, a drive circuit 8 which feeds a high frequency current to the heating coils 3, 7 by converting an AC voltage into a high frequency voltage, and a ring-shaped magnetic shield ring 12 arranged to surround the heating coils 3, 7. The magnetic shield ring 12 is formed so that the amount of magnetic flux to be shielded increases for a part of a portion facing the adjoining heating coils 3, 7 when compared with a portion not facing the adjoining heating coils 3, 7. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
