PURPOSE:To prevent the undersirable influence exerted on other apparatus by eliminating a fact that a container becomes a noise source by connecting the container to a power source or one power source line of an inverter circuit through a capacitor, etc. CONSTITUTION:When a pot 3 is inserted into a housing part 2, a pot detecting device 10 provided on the center part of the bottom of the housing part 2 is activated, and a control part 13 sends a heating starting signal to an inverter circuit 8 and a heating stand-by state is set. Subsequently, when a cooking mode is set by a cooking menu key of an operation display part 11, the inverter circuit 8 supplies a high frequency current to heating coils 4 and 5, the heating coils 4 and 5 bring the pot 3 to induction heating directly and cooking is started. In this case, since the pot 3 is connected to the minus power source line of the inverter circuit 8 through the metallic heat receiving plate of the pot detecting device 10 and a capacitor, the potential of the pot 3 can be set to the same as the minus potential of the inverter circuit. Accordingly, it can be prevented that the pot 3 is brought to inductive coupling electrically to a power source line or a wiring of the inverter circuit 8, etc., and a noise is induced, and the pot 3 itself becomes like an antenna for radiating a disturbing radio wave and disturbs other apparatus. |
