ABSTRACT:
A holding oven designed for creating a natural convection current in the chamber of the oven, and constructed by fixing the heater element to a first material characterized by its high thermal conductivity for rapid build-up of thermal gradient into an insulated space, while that heater element is simultaneously in contact with a second material which is characterized by its high thermal capacitance for slowing thermal discharge upon repeated opening and closing of oven doors. The first material forms a heat sink and the second material forms a heat bank and the heat sink/bank is adapted to maintain a safe holding temperature over a more extended period of time in a power off mode.
