ABSTRACT:
A microwave oven providing the combination of dielectric heating by the use of microwaves and resistive heating for scorching the surface of a food. An isolation chamber for accommodating an article to be heated by a resistive heater is formed adjacent to the resistive heater provided in a heating cavity. When heating by the resistive heater is desired, the article to be heated is accommodated in the isolation chamber so that it is heated either both by dielectric heating and resistive heating or solely by resistive heating for scorching in an effective manner and at the same time minimizing the contamination of the heating cavity. In this manner, the application of the microwave oven may be widened and the usefulness of the microwave is enhanced.
