The power is then switched to match the cooking mode. As a result, as shown in Figure 4, maximum power is applied when thermal power is most needed in frozen or room temperature conditions, and the temperature of the food rises and power is turned off before it becomes overcooked at high heat. Therefore, the heating conditions are suitable for cooking. The conventional example in which cooking is performed with the power turned off from the beginning is as shown by the broken line in FIG. 4, and it is clear that according to the present invention, quick and high-performance cooking conditions can be obtained.

Furthermore, preheat conditions will be automatically set when cooking cakes, etc.
It is an easy-to-operate cooking utensil.
