Abstract

The present invention relates to a microwave heating device, and in particular, a microwave heating device with a microwave heating element mounted on the surface of a heating dish on which food is placed inside a heating chamber.The microwave heating device according to the present invention includes a heating chamber for placing an object to be heated; a magnetron for generating microwaves; a waveguide for supplying the microwaves generated by the magnetron through the bottom of the heating chamber; a heating dish on which the object to be heated is placed; a microwave heating element positioned on the bottom surface of the heating dish to generate heat by absorbing microwaves; and an access passage for allowing the microwaves supplied by the waveguide to reach above the heating dish from below the heating dish.The object on the heating dish is heated by the heating dish, which is heated by the microwave heating element and by microwaves that reach above the heating dish. Therefore, the surface and the inside of the object can be heated in a simple and quick heating operation.
