A heating device for a hob has a flat rectangular carrier with an outer edge, two heating elements which each have a heating conductor and which together form a heating area and which are fastened on the carrier, wherein each heating element defines a partial heating area, and the partial heating areas are situated inside the rectangular shape of the carrier. The heating elements and their partial heating areas can be operated independently of one another. The partial heating areas of the heating elements do not intersect. A first partial heating area is rectangular and extends, by way of at least one of its outer sides, to the outer edge of the carrier and runs parallel in relation to the outer edge. A second partial heating area covers the portion of the rest of the carrier which is left free by the first partial heating area. Various configurations of heated areas can be achieved owing to the independent operation.

A cooking appliance, such as a toaster or oven, has a lifting arm including ribs that form a support surface for a food product in a cooking cavity of the appliance. Each rib can include an opening configured to permit infrared radiation from a heating assembly to pass through the rib to the food product supported by the lifting arm and/or to reduce a thermal mass and capacitance of the lifting arm. The heating assembly can include a support and/or heating element with a curved shape having a concave side facing a cooking cavity. The support and/or heating element can have a planar shape when unstressed and a curved shape when stressed. The heating element may be coupled to the support so as to be slidably movable relative to the support, e.g., so the heating element can slide relative to the support.

An electric composite heat oven provided with a sight window of a transparent planar heating element is provided. Since the electric composite heat oven has a structure in which a heater heating element is installed, being lower than the upper end of a cooking container, on the front and rear sidewalls of a cooking chamber of an enclosure and a transparent planar heating element is installed over an opening of the cooking chamber of the enclosure, radiant heat may actively control various disturbances that occur during cooking depending on a place where the oven is installed and a change in temperature, whereby there is an effect of providing the optimum heat power depending on a cooking material and also shortening cooking time.

A heating element for a cooking appliance includes terminals that act as electrically conductive contact points. One or more buses are arranged between the terminals, and connect one or more heating element segments in a zig-zag configuration. The heating element segments are connected in series and are arranged parallel with one another. Each heating element segment includes a plurality of cutouts linked together and having an elliptical shape. The terminals, heating element segments, and buses are a continuous single sheet of conductive material. A method of making the heating element includes forming a pattern into the sheet of conductive material by etching the pattern into the conductive sheet using photolithography.

The disclosure provides an automatic smokeless oven with far infrared heating including a seat body, a rotating device, an air treatment device and a cooling device. The infrared heater is positioned above a first cavity and used for heating the first cavity so as to prevent grease, sauce and the like from contacting a heating source to generate oily smoke. The rotating device is arranged in a second cavity and used for driving the food to be baked to turn over, so as to realize an automatically turning over of the food. The air treatment device is arranged at the bottom of the first cavity and used for filtering the air in the first cavity to further reduce smoke emission. The cooling device is arranged at the bottom of the first cavity and communicated with the third cavity for driving the cooling water to flow through the third cavity.

An automatic oven having a controller and a sensor assembly for automatically determining a food type for a food item placed in a cooking chamber of the automatic oven, and cooks the automatically determined food item according to a cooking profile selected based on the determined food type, while optionally accommodating a user input on the determining of the food type, and the cooking profile, including an optional degree of doneness.

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.

There is provided a cooking apparatus for cooking food items, the cooking apparatus dimensioned to be placed on a kitchen countertop, the cooking apparatus including: a housing including a top side, a bottom side, a front side, a rear side, a first elevated side, and a second elevated side; a plurality of cooking compartments each defining a cooking cavity and including a heating element, each cooking compartment defining an opening to the cooking cavity for receiving one or more of the food items to be cooked by the respective heating element, the respective openings of the cooking compartments are vertically spaced along the front side in a stacked arrangement; and a cooking control to control operation of the cooking compartments

The present invention comprises a precision cooking oven that utilizes laser sheets to cook food, thus creating homogeneously heated and uniformly seared food bodies and surfaces. Laser sheets move back and forth evenly injecting heat into items being cooked. All food cold or hot areas can be eliminated since intersecting laser lines can be completely projected on and accommodate an item's exterior surfaces. Items with non-uniform cross-sections and properties can be cooked uniformly by controlling the exact amount of energy projected into differing sections of the food. The oven is also capable of cooking autonomously. Since laser sheets can be precisely controlled, cooking results can be very predictable once the boundary conditions for a thermal analysis are determined. The oven can detect the properties of the items to be cooked and thereafter compute the needed time and power to achieve the desired results stipulated by an oven operator.

An automatic oven having a controller and a sensor assembly for automatically determining a food type for a food item placed in a cooking chamber of the automatic oven, and cooks the automatically determined food item according to a cooking profile selected based on the determined food type, while optionally accommodating a user input on the determining of the food type, and the cooking profile, including an optional degree of doneness.
