  • Microwave oven with a projection for uniform heating within the cavity
    Patent number: 5698128
    Abstract: A microwave oven in which a plurality of projections are formed on an interior surface of a cavity for reflection and distribution of microwaves. The plurality of projections are dispersedly arranged so that neighboring projections do not contact each other. With this arrangement, microwaves can be efficiently distributed within the cavity, since the interior surface of the cavity does not have any depressions which would converge microwaves.
