Systems and methods for user configurable cooking appliances include receiving system resources having associated budgets, facilitating user allocation the system resources to a plurality of heating elements without exceeding the associate budgets, applying the system resources to the heating elements to heat one or more food substances within a cooking chamber, and selectively regulating delivery of the system resources to the heating elements such that no more than the associated budget of each of the system resources is delivered to the heating elements. Computing components can execute a heating algorithm to cook at least one food substance in the cooking chamber, detect a state change of the food substance, and modify the heating algorithm to reconfigure the system resources supplied to the heating elements in response to the state change and in accordance with user configured allocation and associated budgets for the system resources.

The invention discloses a rotatable multi-functional reflection heating plate structure, comprising a heating component, wherein a reflector is disposed above the heating component; the reflector is connected with a household appliance through a rotating shaft; the reflector rotates around the rotating shaft; the heating component consists of a heating plate, an electrical heating pipe and a fixed board; the fixed board is fixedly connected with the household appliance; the heating plate is disposed above the fixed board; and the electrical heating pipe is disposed in the gap between the heating plate and the fixed board. In the invention, the reflector is fixed above the heating component using the rotating shaft, so the reflector does not fall down because of loose fixation; the heating component plays a good heat reflecting role, so foods can be roasted quickly; meanwhile, the assembling structure is simple and the cost is low.

Several embodiments include a cooking appliance/instrument (e.g., oven). The cooking appliance/instrument can include a cooking chamber, a support tray adapted to hold food in the cooking chamber; and a heating system comprised of at least a heating element. The heating system is adapted to emit waves according to a particular configuration such that the emitted waves is substantially transparent or substantially opaque to the support tray and thus enabling the cooking instrument to select what to heat.

A heating device has a sheet-like heating element and a holding device for the heating element, wherein the heating element is held along an outer edge on the holding device and, by way of at least 70% of its surface area, runs freely within the holding device. The heating element has a weave which at least partially contains heating conductor material. Therefore, warp threads can advantageously be composed of electrically conductive heating conductor material, and weft threads can be composed of carbon fibre or ceramic fibres. The heating element can be centrally supported or be provided with a structuring over its surface area, which structuring stabilizes the heating element, for example can be corrugated.

A high speed cooking apparatus employing a low voltage high current system for heating foods employing a novel wire mesh heating element. The system herein described providing the benefits of high speed cooking like that further described by U.S. Provisional Application 60/822,028 filed on Aug. 10, 2006, but yet providing significant cost benefit and simplicity over said system.

A grill includes a reflector below a heating clement with a plurality of reflector panels each having a first position oriented parallel to the cooking surface and a second position oriented non-parallel to the cooking surface.

A body defines a void and an aperture and has a reflective surface, the void communicating with the aperture and the reflective surface presenting towards the aperture. A structure, adapted to produce infrared radiation, is positioned in the void such that infrared radiation produced by the structure is directed to the aperture. An optical filter is positioned to at least substantially occlude the aperture, the filter being adapted for through passage of the infrared radiation directed to the aperture and further being adapted to restrict the through passage of visible light.
