1. An induction cooking device comprising:
a top plate formed of a light permeable material; a plurality of heating coils disposed beneath the top plate being operable to generate an alternating-magnetic field and heat a target heating object placed on the top plate inductively; an inverter circuit being operable to supply a high-frequency current to the heating coils; a control unit being operable to control the inverter circuit; an operation unit being operable to enter and operate commands for heating control of the target heating object; and a plurality of light-emitting parts provided near the outer circumference of the heating coils, wherein the control unit has a heating control unit operable to control the output of the inverter circuit, and a light-emission control unit is operable to control the light emission of the light-emitting parts, depending on the input from the operation unit, and wherein the control unit is configured to set a heating mode which corresponds to a command inputted to the operation unit, the heating mode including a first heating mode and a second heating mode:
the first heating mode in which the heating control unit causes one heating coil among the plurality of heating coils to operate singularly for heating one target heating object and the light-emission control unit causes only the light-emitting parts provided near the outer circumference of the one heating coil which operates singularly, andthe second heating mode in which the heating control unit causes two or more adjacent heating coils having centers at different positions to operate cooperatively for heating one target heating object and the light-emission control unit causes the plurality of light-emitting parts to operate such that the light-emitting parts disposed between the adjacent heating coils are turned off and indicate the vicinity of the outer circumference of the two or more adjacent heating coil, and wherein, when the operation unit receives a command for turning on a power of a main body, the control unit sets a heating area sequential display mode for turning on the light-emitting parts before the heating mode is set, and wherein, during the heating area sequential display mode, the heating control unit stops operation of the plurality of heating coils and the light-emission control unit sequentially performs a first illumination mode and after or before the first illumination mode, a second illumination mode,
the first illumination mode indicating the vicinity of the outer circumference of the heating coil which singularly operates when the first heating mode is set, andthe second illumination mode indicating the vicinity of the outer circumference of the adjacent heating coils which cooperatively operate when the second heating mode is set with the light-emitting parts disposed between the adjacent heating coils turned off. |
