Reference numeral 4 denotes an operation panel provided on the front side of the main body 1. As shown in FIG. A method switch 6, a cooking menu switch 7, a heating temperature setting switch 8, and a heating time setting switch 9 are provided.

Such complicated heating operations, control, and display thereof have become possible in recent cooking appliances by employing microcomputers (hereinafter referred to as microcomputers).

Therefore, by having the microcomputer determine the cooking operation mode instruction means that matches the preferences of the destination, etc., heating control corresponding to the display contents can be performed even with the same cooking device by simply changing the display contents of the cooking menu switch 7. be.

For example, the cooking menu switch 7 in FIG. 2a is mainly for meat and fish dishes, and the switch 7 in FIG. Therefore, as the operation mode instruction means shown in figures a and b, the operation mode corresponding to the cooking content displayed on switch 7 of the cooking menu can be set with a resistance value, and the resistance value can be stored in the microcomputer. The format can be determined by a microcomputer.

As another example in FIG. 3, since the frequently used menus differ depending on the destination and the user, the frequently used menus are attached to the cooking menu switch 7 of the operation panel 4, and as an operation mode instruction means. It is sufficient to set an operation style corresponding to this display content. Here, the microcomputer reads the pressed key of the cooking menu switch end together with the contents of the operation mode instruction means, determines the operation mode, and performs heating control and display of the operation mode. Therefore, if the arrangement of the switches in the cooking menu is the same, but the contents of the menu and the operation mode instruction means are changed, switch 7 in the cooking menu shown in Figure 2a will be used for grilling, and switch 7 in the same figure will be for spinach.
