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).

The present invention relates to a thawing-apparatus, in which a substance is preferably heated. The present invention further relates to a method to thaw a substance with radio-frequency waves.

Provided is an apparatus and method for protecting against unsafe electric current conditions. A protections circuit may be used in a device, such as an electric grill, that has one or more electric loads, such as heating elements. The protection circuit may protect against various failure scenarios, including, without limitation, instances of ground fault, over current, driver failure, and failure of a microprocessor. In response to a failure, the protection circuit may trip a latch relay or disable a triac driver to stop current from flowing.

The invention relates to a combination of an electrical heating element and a heat dissipater to be heated thereby; the heating element comprises a substrate, an insulating layer located on the substrate and a thick film conductor located on the insulating layer, wherein the second side of the metallic substrate is in contact with the heat dissipater, comprising a layer of metallic material on its face towards the heater and wherein the substrate is brazed to the heat dissipater and the surface of the heating element over which the thick film conductor extends, is substantially equal to the surface of the heat dissipater. The brazing leads to a permanent contact between the heating element and the heat dissipater, so that the possible tendency for warping as caused by the heating and cooling cycles will be withstood.

Appliances comprising a base unit and a plug connector coupled to the base unit. The plug connector is configured to electrically couple the appliance to a first socket connector of an electrical receptacle. A channel is formed on or in a first sidewall of the base unit. The plug connector is disposed in the channel when in an engaged position. A defines a channel wall of the channel. The lever is configured to facilitate a transition of the plug connector between the engaged position and a disengaged position. The lever engages the plug connector when in the engaged position and does not engage the plug connector when in the disengaged position.

Autonomous hydraulic unit comprising a liquid inlet (1); a flow meter (2) which is jointly attached to an inlet (3) of a compression chamber (4) of a pump (5) where a piston (6) injects the compressed liquid through a nozzle (7) into a heating chamber (8).

A plastic body (9) integrates in one piece the compression chamber (4), a self-priming valve (10) and a safety valve (11). A heating element (12) contained within a body (9) determines with a disk (14) the heating chamber (8) where the temperature of the liquid injected by the piston (6) is raised in its passage towards the outlet (13).
