ABSTRACT:
A microwave oven includes a heating space in which a motor-driven turn-table is disposed. A drive shaft for the turn-table extends upwardly through the floor. A shielding member is mounted to the underside of the floor and includes a horizontal wall portion having a second hole through which the drive shaft extends. A plurality of reflectors are upstanding from the horizontal wall portion and are circumferentially spaced about the second hole. The reflectors reflect microwaves toward the floor to dampen the microwaves. Slots formed in the horizontal wall portion outside of the reflectors conduct heat to a chamber located below the horizontal wall portion in which a motor is mounted for rotating the drive shaft.
