Abstract
A microwave heating device for heating a material in a heating room by microwave radiation produced by a microwave oscillator. The heating device includes an outer waveguide for channeling the microwave radiation from the microwave oscillator into the heating room. The outer waveguide is connected at a first end to the heating room. The microwave heating device also includes a rotary reflector unit disposed adjacent to the first end of the outer waveguide, for uniformly distributing the microwave radiation in the heating room. The rotary reflector unit includes a reflector member positioned to receive the microwave radiation from the outer waveguide for reflecting the microwave radiation, and a drive device for rotating the reflector member to cause irregular reflection of the microwave radiation.
