Abstract
Radiant-energy heating and/or cooking apparatus has an infrared-wavelength radiation-producing element, a reflector for concentrating the infrared radiation and a coverplate through which the concentrated radiation is transmitted to a recipient material, e.g. foodstuffs to be cooked. The coverplate has first and second surface members separated from one another by a honeycomb of tubes; the members and tubes are fabricated of an infrared-transmissive material. The resulting honeycomb coverplate has low infrared absorption and great mechanical strength capable of withstanding severe thermal shock.
Claims12
Apparatus for at least one of radiant-energy heating and radiant-energy cooking, comprising:
- heating means for producing at least infrared-wavelength radiation;
- means for directing substantially all of at least said infrared-wavelength radiation from said heating means toward a surface;
- a coverplate comprised of:
- a first member substantially defining said surface;
- a second member spaced from said first member and between said first member and said heating means;
- and a honeycomb structure disposed between, and substantially joined to, said first and second members;
- said coverplate having substantial transmission of said at least infrared-wavelength radiation therethrough to said surface.
