ABSTRACT:
A cooking state displaying apparatus and method for a microwave oven combined with a television. The apparatus includes a body sensor for sensing if there is a person near the microwave oven, and in accordance with the sensed output from the body sensor during cooking, selectively displays the current cooking state and completion on an LED displayer installed on the front side of the microwave oven or on a TV screen. Also, in accordance with the sensed output from the body sensor, a cavity lamp in the microwave oven is selectively turned on/off and the loudness of a buzzer sound for indicating completion of cooking varies. Therefore, it is convenient to use and it is possible to save power consumption.
