<p>A microwave heating device for heating a material in a heating room by means of a microwave radiation produced by a microwave oscillator, comprising an outer waveguide for channeling the microwave radiation from the microwave oscillator into the heating room, which outer waveguide is connected at its one end to the heating room, the microwave heating device further comprising a rotary reflector unit disposed adjacent to the above one 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 drive means for rotating the reflector member to cause irregular reflection of the microwave radiation.</p> |
