Abstract
A microwave oven cavity of a microwave oven having an antenna assembly axially supported on one wall of the cavity. The antenna assembly includes an antenna rotating assembly having a bushing mounted in the wall, a bearing axially supported in the bushing, a probe antenna supported in a bearing and extending into the cavity, a directional rotating antenna attached to the probe antenna, and an antenna rotor having a plurality of turbine vanes affixed to the directional rotating antenna which axially drive the directional rotating antenna when forced by air flow velocity circulated through the cavity. The antenna rotating assembly, the directional antenna, and the antenna rotor are integrated for installation and removal from within the confines of the cavity. The antenna assembly engages and locks in position in the wall of the cavity. A grease shield provides for predetermined defined directional air flow velocity of air circulated through the cavity, provides for rotation of the antenna rotor assembly supported on the directional rotating antenna of the antenna assembly for uniform energy distribution and consistent heating within the cavity, provides for passing air through the cavity and past the door of the cavity to keep the cavity free of vapors and the door free of moisture, and provides for exhausting of the vapor and moisture out through the top wall of the cavity and through an exhaust vent in the front of the microwave oven.
