Abstract
The invention provides a grill configuration which enables a 2400 Watt or smaller electric heating element to provide cooking temperatures of at least 500.degree. F. when food is present on a grill area of at least 200 square inches. The electric grill includes an electric heating element and a multilayer metal sheet insert shaped to reflect radiation heat from the heating element to impinge on the food present on the grill surface. The multilayer metal sheet insert is preferably metal foil layers which provide maximum insulation and heat containment to increase the efficiency of the limited heat available from the electric heating element of the grill.
Claims21
An electric cooking device comprising:
- a housing including upper and lower housing members;
- a cooking surface positioned within the housing;
- an electric heating element positioned within the housing for cooking food which has been placed on the cooking surface, the electric heating element operating on a 110-120 volt AC or 220 volt AC residential power supply;
- at least one multilayer metal sheet insert positioned in the upper housing member for radiating, and reflecting radiation from the electric heating element to the cooking surface and achieving cooking temperatures of at least 500.degree. F. at the cooking surface;
- wherein the combination of a 2400 watt or smaller electric heating element and the at lease one multilayer sheet insert achieve the cooking temperature of at least 500.degree. F. substantially across 200 square inches of the cooking surface;
- and
- wherein the multilayer metal sheet insert is positioned within the upper housing member with a standoff distance between the insert and an inside surface of the upper housing member varying across the upper housing member.
An electric cooking device comprising:
- a housing including upper and lower housing members;
