INDUCTION HEATING COOKING APPARATUS

摘要

PURPOSE:To provide an induction heating cooking apparatus which can be accomplished at a low cost and in which the magnetic field leaking peripherally from the heating coil is less. CONSTITUTION:Closed loops are formed from a conductive wire and a plurality of shield members 20 are mounted in layers on an electric wire mounting part 19 provided on the outer side face of a heating coil holding table 13. The high frequency magnetic field of a heating coil 15 is in interlinkage with the shield members 20 to induce therein a high frequency current, which generates a magnetic field, and thereby the magnetic field leaking peripherally from the heating coil 15 is suppressed. Laminating of a plurality of shield members 20 increases the magnetic flux which sets off the magnetic field of the heating coil 15. Formation of the conductive wire in closed loops permits simplifying the configuration and allows reduction of the material costs.
