Abstract
A microwave heating apparatus comprises a heating oven chamber for receiving a substance to be heated and a magnetron with an anode cylinder for generating heat. The magnetron is positioned above the oven chamber, and, not only its output antenna to emit microwaves to the substance, but also its anode cylinder are exposed within the oven chamber. The heat generated by the anode cylinder is supplied into the oven chamber to elevate the temperature therein. As a result, the substance in the oven chamber is heated not only by the microwave but by the heat from the anode cylinder.
