Radiant-energy heating and/or cooking apparatus with honeycomb coverplate

摘要

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.
