Abstract
A two level turntable adapted for use in a microwave oven. The top level platform which may include a roasting rack is removably supported above the bottom level by a plurality of columns. The bottom level platform has a shaft that extends downwardly through an aperture in a microwave shielding enclosure to a motor. The motor components consisting of a coil spring and a braking mechanism are mounted in substantially the same horizontal plane to provide a relatively low vertical profile. Although the low profile is important when the bottom level platform is used by itself, it is even more important when the top level platform is mounted on top. The shielding enclosure which includes a pan shaped bottom has a downwardly bent lip from the lid to provide a low microwave field region adjacent to the connection of the pan and lid.
