摘要： 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 conductor and the second material forms a heat sink and the heat conductor is adapted to maintain a safe holding temperature over a more extended period of time in a power off mode. An ergonomically designed operating panel provides an interactive intuitive method of programming the desired cooking sequences. Remote operation and programming is accomplished using preprogrammed software on a conventional home computer via a modem. Switch selections are monitored by a microprocessor which branches to the various preprogrammed functions. In addition, self-analysis and self-diagnostics aid the user in displaying a walk-back of the stored times and temperatures that occurred during an operating cycle before a power outage.
