An electric roasting machine includes a housing defining a cavity having an upper opening, a heating device installed in the cavity, and a grill located at the opening of the cavity. The grill includes a carrying part extending into the cavity and located in a region covered by thermal radiation of the heating device.

The invention relates to a method for operating a heating element (210), in particular in a food processor (1) for the at least partially automatic preparation of foodstuffs, wherein the following steps are performed: a) detecting an electrical resistance of the heating element (210) such that at least one resistance value is determined, b) performing a heating operation on the heating element (210) based on the at least one determined resistance value to perform the heating operation depending on a temperature of the heating element (210).

A low-temperature baking smoking set includes a hollow heating base body (31) in which a heating cabinet for accommodating smoking material is formed, an infrared coating layer (32) coated on an outside of the heating base body (31), a first electric module (331, 341, 351, 361, 371) disposed outside the heating base body (31) and electrically contacted with the infrared coating layer (32), a second electric module (332, 342, 352, 362, 372) disposed outside the heating base body (31) and electrically contacted with the infrared coating layer (32), and a powering unit (5). At least a portion of the infrared coating layer (32) is disposed between the first electric module (331, 341, 351, 361, 371) and the second electric module (332, 342, 352, 362, 372). The powering unit (5) is electrically connected with the first electric module (331, 341, 351, 361, 371) and the second electric module (332, 342, 352, 362, 372) to electrify the at least a portion of the infrared coating layer (32) for generating infrared lights so that the infrared lights penetrate through the heating base body (31) to heat the smoking material in the heating cabinet by infrared radiation. Since infrared lights have a stronger penetrability and are able to penetrate smoking material located at an outer periphery of the smoking material in the heating cabinet to reach an interior of the smoking material in the heating cabinet, the smoking material in the heating cabinet can be heated much uniformly.

An electric roasting machine includes a housing defining a cavity having an upper opening, a heating device installed in the cavity, and a grill located at the opening of the cavity. The grill includes a carrying part extending into the cavity and located in a region covered by thermal radiation of the heating device.

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.

An electric grill configured for cooking food and a method of cooking food using the electric grill includes a housing that defines an open interior and an aperture. Element frames are positioned at the sides of the open interior. Electric heating elements are positioned within the element frames and are positioned within the open interior exterior of the aperture in a direction towards the housing. The electric heating elements generate IR energy that is directed towards a middle of the open interior below the aperture. Heat energy exits the housing through the aperture by radiative heat transfer and convective heat transfer. Such convective heat transfer includes air currents circulating within the open interior past the electric heating elements and out of the aperture.

A heated dish system includes a dish; and a heating apparatus to removably hold the dish, the heating apparatus having a base to receive the dish; a control system having an internal power source to charge via an external cable to plug into an electrical port; and one or more inserts to heat via receiving power from the internal power source; the one or more inserts are to be inserted into the dish to heat food within the dish.

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.

A carbon heating element and a method for manufacturing a carbon heating element are provided. The carbon heating element may efficiently dissipate heat and prevent disconnection or destruction of a heating element to prolong a lifespan thereof without generating a spark and plasma under a high voltage. The carbon heating element may include carbon (C) and silicon carbide (SiC), and the carbon heating element may have a thermal conductivity of 1.6 W/m.Math.K or more.

A carbon heater is provided that may include a carbon heating element that functions as a heat source; a tube that encloses the carbon heating element; and at least one groove that extends from an outer peripheral portion of the tube in a direction toward a center of the interior of the tube, the carbon heater being capable of preventing a dielectric breakdown, a spark, and plasma therein from occurring, and breakage or destruction of the heat source made of the carbon heating element.
