Abstract
A food heating and cooling device including a tray, at least one main dish plate in the tray, at least one secondary dish plate in the tray, a cover associated with the tray for maintaining the food hot or cold, an inducer for heating, reheating or maintaining heat and powered by an electronic generator circuit which induces currents in an armature located on or under the plates, a thermoelectric exchanger for maintaining the food cold or cool by extracting residual heat from the plates and compensates for thermal insulation leaks from the tray and cover, and rechargeable batteries connected to the inducer and the thermoelectric exchanger.
Claims22
A food heating and cooling device comprising:
- a tray;
- at least one main dish plate in the tray;
- at least one secondary dish plate in the tray;
- a cover associated with the tray for maintaining said food hot or cold;
- an inducer for heating, reheating or maintaining heat and powered by an electronic generator circuit which induces currents in an armature located on or under said plates;
- a thermoelectric exchanger for maintaining the food cold or cool by extracting residual heat from said plates and compensates for thermal insulation leaks from said tray and cover;
- and
- rechargeable batteries connected to said inducer and said thermoelectric exchanger.
A system for maintaining temperature of prepared meals comprising:
- a tray having a fitted cover, a first zone sized and shaped to receive a principal plate for hot food, at least a second zone sized and shaped to receive an appetizer or a dessert on appetizer plates and at least one Peltier effect module, wherein said Peltier effect module transfers heat between interior portions of the tray and the exterior of the tray,
- power-supply batteries associated with the tray enabling self-contained use;
- a circuit for controlling said Peltier effect modules;
- and
- an induction generator for maintaining the tray at a refrigerated temperature and selective heating of the first zone.
