Abstract:
An infrared food warming device comprising:(a) at least one compartment having at least one food shelf and at least one opening for placing food to be warmed on said food shelf in said compartment;(b) at least one infrared energy generating sheet positioned in said compartment adjacent to said at least one food shelf, said infrared energy sheet further comprising:i) a fiberglass support grid;ii) a layer formed on said support grid, said layer comprising a mixture of carbon and polymeric materials capable of producing infrared radiation in response to electrical current passed therethrough;iii) a pair of electrical conduction power strips along opposite sides of said layer;iv) a polymetric laminate enclosing said support grid, said layer and said electrical conduction power strips, said polymetric laminate being substantially transparent to infrared radiation;v) input power terminals connected to said electrical conduction power strips; and(c) an electrical power source connected to said input power terminals for providing electrical power to be passed through said power strips and said layer of carbon polymer mixture to generate infrared radiation therefrom.
