<p>Disclosed is a microwave cooker wherein a relay does not perform ON/OFF operation which does not contribute to the heating output of a microwave generating apparatus immediately prior to termination of heating, and wherein the replacement time of the relay can thus be delayed by a corresponding amount. In the microwave cooker, the heating output of a microwave generating apparatus (8) is controlled by supplying power to the microwave generating apparatus (8) through relay contacts (57a) and setting the fixed-period ON time and OFF time of the relay contacts (57a) in accordance with the set heating time and heating output. The microwave cooker is provided with: means (70) for judging whether or not the time corresponding to the final period within the heating time is equal to or less than the set ON time of the relay contacts (57a); and means (70) for eliminating the ON time of the relay contacts (57a) in the final period by extending the ON time of the relay contacts (57a) in the preceding cycle by the amount of the ON time of the relay contacts (57a) in the final period, if the means (70) judges that the time corresponding to the final period is equal to or less than the set ON time.</p> |
