ABSTRACT:
An improved apparatus for heating and cooking foods includes an oven frame having an interior formed as an oven chamber, a turntable turnably supported on the bottom of the oven chamber, a plurality of rollers rotatably disposed between the turn dish and the outer peripheral region of a bottom plate, and a mechanism which projects downward from the bottom of the turntable which prevents the turntable from sliding on a table surface. The rollers are rotatably received in an annular groove located around the outer peripheral region of the turntable. The mechanism for preventing sliding of the turntable is that of an annular trough having a V-shaped sectional shape. The lowermost part of the annular trough is located lower than the rolling surface for the rollers. In a second embodiment the mechanism for preventing sliding of the turntable is a plurality of downward projections formed around a single circle in an equally spaced relationship.
