Abstract
In order to boil eggs or other foods not suitable for cooking with direct microwave radiation, a receptacle containing such foods is separated from a microwave source by a radiation shield while an adjacent heating vessel partly filled with water is exposed to the microwaves. This vaporizes the water and the resulting steam is admitted into the receptacle for a rapid heating of its contents. The shield may adjoin the vessel walls and may reflect the incident microwaves into the water bath. In a simple case, the food receptacle and its shield may be replaced by a metal foil--e.g. of aluminum--in which the foods to be boiled are loosely wrapped while lying in a shallow pool of water within the microwave-irradiated heating vessel.
Claims4
A device usable with a cooking stove equipped with a microwave source for rapidly boiling foods not suitable for cooking with direct microwave radiation, comprising:
- a vessel positionable below said source in a field of microwaves incident from above, said vessel comprising a metallic bottom and a metallic peripheral wall, said vessel forming a vapor space above an area reserved for a quantity of water to be vaporized by incident microwaves;
- a receptacle overlying part of said vessel and communicating with said vapor space for admitting evolving steam to foods disposed in said receptacle;
- and
- a radiation shield covering said receptacle for protecting the contents thereof from said microwaves, said receptacle and said radiation shield leaving a portion of said vessel exposed to microwaves incident from above, said area extending into said exposed portion.
