Abstract
A microwave oven includes a control circuit provided for properly heating food on the basis of detection by an alcohol sensor. Upon depression of a beverage key of an operation panel, the control circuit detects change rates of signals generated by the alcohol sensor before the heating operation and during the heating operation. When the change rates exceed respective reference values, beverage to be heated is determined to be Japanese sake. When the determination before the heating operation does not coincide with that during the heating operation, the control circuit determines which the beverage is, the sake or the milk or the other type of beverage, on the basis of the determination both before and during the heating operation, setting a driving period of time of a magnetron accordingly.
