Abstract
An induction cooking device includes a control unit and a plurality of light-emitting parts. The control unit includes a heating control unit that controls the output of an inverter circuit and a light-emission control unit that controls the light emission. When receiving a command for starting with one heating coil, the control unit turns on only the light-emitting parts provided near the outer circumference of the heating coil for starting heating, and when receiving a command for starting heating with two or more adjacent heating coils, the control unit turns off the light-emitting parts disposed between the heating coils for starting heating among the light-emitting parts provided near the outer circumference of each one of the heating coils for starting heating, and turns on the remaining light-emitting parts.
