ABSTRACT:
An energy transmission and distribution system for use in a microwave oven wherein a waveguide member is provided for guiding microwave energy from a generator to an inlet opening to the oven cavity. An impedance matching device is mounted within the waveguide for matching the impedance of the oven cavity and waveguide to that of the generator. A deflector shield is mounted within the cavity adjacent the inlet opening for deflecting microwave energy passed through the inlet opening and effectively preventing direct illumination of the cavity by the microwave energy. A rotating stirrer is mounted within the cavity adjacent the inlet opening and adjacent the deflector shield and cooperates with the deflector shield to provide improved uniform distribution of the microwave energy in the oven cavity.
