Microwave oven with electric heater adjustable to different positions

摘要

A microwave oven includes a cooking chamber, a magnetron for directing microwaves into the chamber, and an electric heater disposed within the cooking chamber. The heater is mounted for rotation about a horizontal axis so as to be moved between horizontal and vertical orientations. A fan disposed outside the cooking chamber blows air through apertures formed in a wall of the cooking chamber to cause heat within the cooking chamber to be circulated. The heater is of inverted U-shape when vertically oriented and is rotated by an electric motor between the vertical and horizontal positions.
