ABSTRACT:
An automatic cooking appliance has a magnetron to cook the food. The cooking appliance has a dial, which is rotatable and capable of being pressed, on an operation panel thereof. A cooking mode in the menu is selected due to the rotation of the dial. The cooking mode is determined by pressing of the dial. The cooking appliance controls the magnetron in accordance with the determined cooking mode. This enables the dial to be used for multiple purposes to thereby save space on a control panel.
