ABSTRACT:
A heating well for a hot food serving appliance wherein a heat dispersing plate is supported on ledges provided adjacent the lower end of a well housing. An open-top stainless steel well pan fits within the housing with the bottom wall of the pan residing against the heat dispersing plate. A high-temperature electric heating element, mechanically secured against the underside of the heat dispersing plate by tabs, heats the well pan and a removable food pan nested within the well pan. The heat dispersing plate is fabricated from cold rolled steel, or any other suitable material having moderate thermal conductivity, to retard spot heating of the well pan and eliminate, or substantially reduce, thermal cracking of the stainless steel well pan. Simplified assembly of the heating well is accomplished by means of resilient push rivets.
