Abstract
A method of controlling cooking in a microwave oven or an electronic cooking appliance, wherein the cooking can be performed at the optimum condition by sensing a sonic level through a sonic sensor in the case where the cooking is made utilizing a pressure container which produces a sound upon exhausting vapor therefrom. A temperature sensor is provided in addition to the sonic sensor. The heating control is performed to gratify both of the two conditions of the sonic sensor and temperature sensor. To avoid a mis-operation due to noises from a fan motor, a turntable motor and a magnetron, the fan motor, turn-table motor and magnetron are stopped temporarily. Under this condition, the sonic level is sensed once more and the heating control is performed on the basis of the once more sensed sonic level.
