SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and has a press for mounting a container on an upper surface of a main body.
An induction heating coil horizontally disposed below the plate; a control board below the induction heating coil; and a cooling fan for cooling the control board, the induction heating coil, and the like. In an induction heating cooker provided with a light emitting element for notifying the mounting position of the container near the heating coil, the constant value is maintained when the container generating the eddy current by the magnetic flux generated from the induction heating coil is not at a predetermined position on the plate. The light emitting element is turned on for a period of time, and turned off when the container is placed at a predetermined position on the plate.

As described above, in addition to notifying the mounting position of the container, when the container is not at the predetermined position on the plate, the light emitting element is turned on for a certain period of time, and the container is placed at the predetermined position on the plate. Turn off the lights to save energy.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings.

FIGS. 1 and 2 are an external view and an internal structure diagram of a heating cooker according to an embodiment of the present invention. A plate 2 on which a container 7 is placed is provided on the upper surface of the main body 1, and an induction heating coil 8 (one or more) horizontally arranged below the plate 2 and a heating element 15 (resistive load) are provided. The induction heating coil 8 or the heating element 1 having a resistance load.
A roaster 5 (both sides grilled, single side grilled) roasting a fish or the like underneath 5; an induction heating coil 8;
A control board 12 for controlling the roaster unit 5, a cooling fan 14 for cooling the control board 12, the induction heating coil 8, and the like, and an air path structure 13 are provided.

The roaster section 5 has an upper heater 10 and a lower heater 11.

Further, the control board 12 and each heating element 15 are provided with various sensors (not shown) such as a temperature control element and a driving element, and a light emitting element 16 for notifying the mounting position of the container 7 near the induction heating coil 8 is provided. Have.
