Abstract
The disclosed device is a heat-emitting lid for use on top of a standard cooking pan. The device comprises a body including a heat element that radiates heat downward during use. By radiating heat downward, the food item within the pan may be cooked or browned more evenly by heating simultaneously from the top and bottom.
Claims17
A heat-emitting lid for use with a conventional cooking pan, the heat-emitting lid comprising:
- a body formed from:
- a top surface;
- a side wall having:
- a top edge and a bottom edge, the top edge of the side wall attached to the top surface and extending downward to form a cavity;
- an insulated layer configured to prevent the top surface from heating;
- a heating element positioned within the cavity;
- a bottom surface affixed within the cavity, sealing the heating element within the cavity;
- the side wall extending beyond the bottom surface, forming a lower rim;
- a handle affixed to the body;
- a power switch with an on position and an off position, the on position activating the heating element and the off position de-activating the heating element;
- and
- a plunger switch;
- the plunger switch protruding from a lower surface of the handle;
- whereby when the heat-emitting lid is placed on a flat surface, the plunger switch is depressed and the heating element is deactivated;
- whereby the lower rim of the side wall is adapted to surround an upper portion of the conventional cooking pan, preventing the heat-emitting lid from sliding off the conventional cooking pan.
A lid, with a downward-facing heating element, for use on top of a pan, the pan including a rim and an interior, the lid comprising:
- an outer layer of a first material, the outer layer forming:
- a top surface connected to a side surface;
- an interior lower rim;
- a bottom rim that bridges the side surface and interior lower rim;
- an inner layer of insulation adjacent to the outer layer of a first material;
- a downward-facing heating element adjacent to the inner layer of insulation;
- a protective layer that permits the passage of heat from the downward-facing heating element to the interior of the pan;
- and
- a handle affixed to the outer layer of a first material;
- a tilt switch that makes and breaks an electrical circuit based on its rotational position;
- whereby when the lid is placed upside down the tilt switch senses the position and deactivates the heating element.
A device to fit on top of a pan, the device emitting infrared radiation to cook food within the pan, the device comprising:
- a layer of insulation;
- a heating element adjacent to the layer of insulation;
- a protective layer adjacent to the heating element;
- a first layer of material surrounding the insulation, heating element, and protective layer without blocking the path of heat from the heating element through the protective layer;
- the outer layer of a first material adapted to surround the top of the pan to prevent inadvertent disengagement of the lid from the pan;
- a flame detector;
- the flame detector located in optical communication with an interior space created by the combination of the device and the pan;
- the flame detector including a light-sensor;
- whereby the detection of light in excess of a set value indicates the presence of a fire, triggering the flame detector to disable the heating element.
