Abstract
Apparatus for keeping food hot and/or cold includes a body of heavily insulated material in which there are separate recesses for hot food and cold food. The cold food is kept cold by means of an ice compartment located in the bottom of one recess and an exhaustible refrigeration unit located in the top of that recess. The hot food is kept warm by means of an electrical coil in the bottom of the recess and a solar heating panel in the top.
Claims10
A device for keeping some food hot and for keeping other food cold, comprising:
- a heavily insulated body defining first and second generally vertical recesses, said recesses being adapted to receive containers of food, the first recess being designed to keep the food cool and the second recess being designed to keep other food hot;
- a frozen material container located in said first recess;
- an insulating cap closing off the top of said first recess;
- an electrical heating coil in the bottom of said second recess, said heating coil being adapted to warm the food in said second recess when an electrical current is passed therethrough;
- and
- a passive solar heat collector located in the top of said second recess and acting to close off said second recess, said collector including a heat transmissive cap, closing off the recess and solar reflecting panels for directing solar light rays into said heat transmissive cap.
A device for keeping some food hot and for keeping other food cold, comprising:
- a heavily insulated body defining first and second generally vertical recesses, said recesses being adapted to receive containers of food, the first recess being designed to keep the food cold and the second being designed to keep the food hot;
- an insulated cap closing the top of said first recess and a frozen material container located in the bottom of said first recess;
- an exhaustable refrigeration unit being located in the top of the first recess, said refrigeration unit having a tubular section of heat transmissive material located in a hollow portion of said cap and being positioned toward the bottom of the hollow portion;
- an electrical fan located in the hollow portion above the tubular section to create a low temperature air flow;
- and
- a source of heat being located in said second recess.
