Abstract
A microwave oven in which the oven chamber is defined by upper and lower portions each generally triangular in section and which is provided with efficient microwave reflecting and distributing arrangements. The lower portion is defined by a main casing and the upper portion, which includes the oven chamber front and top walls, is defined by a concave portion in a door assembly which is hinged along a rear edge portion and may be pivoted upwards to open positions and downwards to a closed position. When in a completely opened position the door assembly exposes the top and front of the oven, whereby insertion or removal of food may be effected through the top or front of the oven, and the oven permits convenient use when placed at different levels.
