Abstract
A control panel including digital input means is provided in a microwave oven for introducing desired information related to a cooking time period, a cooking mode or a mean output level of a magnetron, and a temperature to be maintained. The information introduced from the control panel is stored in a digital storage means, of which output signals are applied to a digital control circuit for controlling operation of the magnetron. A temperature sensing means is provided in the microwave oven for detecting a temperature of food being cooked. A detection output of the temperature sensing means is introduced into the digital control circuit, which compares the detection output with the temperature information stored in the digital storage means for controlling operation of the magnetron. The digital input means include a defrost switch for automatically programming intermittent defrost cooking.
