0 W, the roaster 45 is 1800 W, and the maximum rated power consumption of the main body 1 is 4000 W.

In such a case, the power consumption operation of each heat source will be described below with reference to FIG.

When only the two heating coils 43 and 44 are energized, the power consumption can be set up to a maximum of 2000 W, and the total power consumption of the main body 41 is 4000 W.

When energizing either one of the two heating coils 43 and 44 and the roaster 45, the heating coil has a maximum power consumption of 2000 W and a power consumption of the roaster 45 of 200.

However, the power consumption required for normal cooking is, for example, from 1200 to 1500 W from an induction heating cooker operated by a 100 V power supply. It is empirically known that the right and left heating coils 43
In the case where both 44 are 1000W, cooking power such as boiling pasta may be hindered by insufficient heat.
Therefore, as in this case, when the maximum power consumption becomes smaller than about 1200 to 1500 W when distributed to two heating coils, the output of one of the heating coils is stopped by the selection switch 48 and the remaining heating coil is reduced to 2000 W. This is to secure thermal power as the maximum power consumption.

As described above, there is no problem in normal cooking.
When the maximum power consumption of all of the plurality of heating coils becomes smaller than about 1200 to 1500 W while reducing the cooking power of the plurality of heating coils by uniformly reducing the maximum power consumption of the plurality of heating coils to 200 to 1500 W Stops the energization of any of the heating coils by the selection switch, and sets the maximum power consumption value of the remaining heating coils to 1200 to 1
Approximately 500 W or more is secured to prevent the cooking performance from being excessively reduced.

In this embodiment, the number of heating coils is two, or the number of heating coils is not limited to two. The number of heating coils may be three or more, and a heating coil for stopping the output may be selected. The heating source other than the heating coil is a roaster, but is not limited thereto, and may be another heating source such as a gradient heater, or a plurality of heating sources may be provided.
