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.

An electric stove includes an electric heating element arranged at a distance from a position right below a target to be heated. A first mirror surface portion is arranged to surround the electric heating element and configured to reflect heat rays radiated from the electric heating elements. A second mirror surface portion is arranged below the electric heating elements and configured to collect the heat rays reflected by the first mirror surface portion to a side below the target by reflecting the heat rays substantially immediately upwardly. The first mirror surface portion includes a plurality of partial elliptical mirror surface portions having one focus near the electric heating elements and the other focus below the electric heating elements, and the second mirror surface portion includes a partial elliptical mirror surface portion a having one focus near the electric heating elements and the other focus below the electric heating elements.

The present invention relates to an electric oven. The electric oven according to an embodiment of the present invention includes a cavity which is provided with an oven chamber, a door for opening and closing alternatively the oven chamber, a carbon heater for providing radiant energy to the inside of a cooking room through the communication opening, a reflector for reflecting the radiant energy from the carbon heater to the inside of the cooking room, and a grate which is fixed to the reflector and is disposed on the communication opening and is provided with a forming section a part of which is formed toward the reflector. Therefore, the grate can be prevented from being damaged according to the electric oven of the present invention.

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 portable heater that includes a ceramic substrate with a heating element configured to define a field of direct radiation, a heat reflector with a concave reflective surface configured to define a field of reflective radiation, a grill cover mounted on the heat reflector, where the ceramic substrate is mounted on an interior side of the grill cover with the heating element facing the concave reflective surface such that the field of direct radiation onto the concave reflective surface is unobstructed.

A cooking device, in particular a steam oven, includes a cooking cavity and a heating unit. The heating unit has a first and a second heating element capable to operate at different temperatures, and at least one fan. The cooking device is configured in such a manner that the fan collects air from the cooking cavity and conveys a first airflow towards the first heating element and a second airflow towards the second heating element. The first airflow passing the first heating element creates a first airflow circuit in the cooking cavity, and the second airflow passing the second heating element creates a second airflow circuit in the cooking cavity. The two airflows can have different temperatures by individually controlling the power of the two heating element.

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.
