Abstract

An infrared food warming device is provided with one or more compartments having one or more food shelves. Food may be placed through an opening on such a food shelf in the compartment. An infrared energy generating sheet is positioned in the compartment on or adjacent to the food shelf. The infrared energy sheet includes a fiberglass support grid, a layer formed on support grid from a mixture of carbon and polymeric materials capable of producing infrared radiation in response to electrical current passed there through. A pair of electrical conduction power strips are attached along opposite sides of the layer and are attached to input power terminals to provide the required current. A polymeric laminate encloses the support grid, the layer and the electrical conduction power strips. The polymeric laminate is substantially transparent to infrared radiation so that it does not become excessively heated. An electrical power source is connected to the input power terminals for providing electrical power to be passed through the power strips and the layer of carbon and polymer mixture to generate infrared radiation that passes through the polymeric laminate and penetrates into the food on the shelf so that the food is warmed.
