A cooking device includes a heating coil having at least two windings. A fixing device is provided to fix the heating coil at least partially mechanically in an assembled state. The fixing device includes a support unit and a retaining unit, which in the assembled state fixes each of the at least two windings separately on the support unit.

A combined apparatus for heating, cooking, grilling and defrosting of foods of various kinds, depending on the type of foods to be treated from time to time and the duration of the foods treatment foreseen by each user of the same apparatus, where each hot treatment of foods may be effected either by heating or by microwaves only, or by heating and microwaves combined to each other. There are described in detail all the technical characteristics of the apparatus and the relative control circuits either for heating or for generating the microwaves. Advantages include use of a sole and single apparatus for hot treating the foods for providing for the heating, the cooking, the grilling and the defrosting of the same foods, instead of employing as it happens hitherto of single separated apparatuses for performing the same functions.

An electric heater includes a substrate and a plane heating element disposed on one surface of the substrate. The plane heating element includes a first pattern portion including a start point and an end point, a second pattern portion that surrounds at least a portion of the first pattern portion and includes a start point and an end point, which are located at an innermost side of the second pattern portion, and a third pattern portion that surrounds at least a portion of the second pattern portion and includes a start point and the end point, which are located at an outermost side of the third pattern portion. The first pattern portion includes a plurality of first tracks that are space apart from each other and have an arc shape that is increasing in length from a center to an outermost side of the first pattern portion, the second pattern portion includes a plurality of second tracks spaced apart from each other and having an arc shape that is increasing in length from the innermost side to an outermost side of the second pattern portion, the third pattern portion includes a plurality of third tracks spaced apart from each other and having an arc shape that is increasing in length from an innermost side to the outermost side of the third portion, and a width of a third track is wider than a width of a first track.

An electronic cutting board which includes a power receiver configured to receive power from a wireless power transmission apparatus, a communication circuitry configured to communicate with the wireless power transmission apparatus, a plate including a display and a protective cover provided to protect the display, a weight sensor configured to measure a weight of an object while the object is placed on the plate, and a controller configured to control the display to display a cutting guide based on the measured weight.

A DC powered cooking appliance which uses an induction or a resistance based DC heating element and excludes AC powered heating elements and preferably does not rely on directly connected combustion powered heating elements. Some embodiments include wattage of 1500 watts or less, voltages of 40 or 48 volts or more and are installed on a boat, van, rv or bus such that an inverter of that boat, van, rv or bus is not electrically connected to the cooking appliance.

A slide-in or drop-in cooking range includes an upper cooktop in the form of a module suspended above an oven cavity. For installation purposes, the upper cooktop can be vertically repositioned relative to the oven cavity to assure proper alignment with the countertop and avoid damage to the cooktop as a result of combined thermal and mechanical stresses over time. The disclosure is particularly applicable to ranges employing glass cooktops having a periphery designed to rest upon edge portions of a countertop and contemplates various mechanisms to perform the cooktop repositioning function, including select mechanisms for locking, ratcheting and biasing the cooktop to establish a desired vertical position for the cooktop.
