Abstract

The present invention is directed to a high-frequency heating device employing microwave heating by a magnetron and heater heating by a heater sheathed by dielectric material. The heating device is internally provided with a wall structure formed in a device housing and having a heating chamber and a heater compartment defined therein. The heater compartment is open towards the heating chamber in communication therewith. The heating device is further internally provided with a magnetron, fixedly mounted in the housing, to supply microwaves to the heating chamber, a dielectric heater accommodated in the heater compartment and extending through opposite side walls of the heater compartment, and one or more metallic rods, disposed near the heater and securely mounted on at least one of the side walls of the heater compartment, to unify an electric field on the heater.
