摘要:
An operating device for a cooktop has a cover with a control panel with a plurality of operating areas. Below the panel, several FSR sensors are positioned. When a control panel is pushed down by a process of operation, the FSR sensor changes its electrical resistance resulting in change of a signals that can be detected and interpreted as operation of the appliance by a user.

A method and the associated device for detecting cooking or boiling processes in a glass ceramic hob are described, to which power is supplied by a power supply by means of a heating element and said power is transmitted to the cooking vessel standing thereon. During a cooking process a temperature profile of the hob is measured and evaluated. The temperature profile is evaluated after ending the power supply and for evaluation purposes a temperature profile gradient is determined. During evaluation, a normal cooking or boiling process is detected if the gradient exceeds a predetermined threshold. During evaluation, a disturbed or faulty cooking or boiling process is detected if the gradient is equal to or smaller than a predetermined threshold. Such a disturbed or faulty cooking or boiling process can arise through the cooking vessel boiling dry or empty.

A normally ungrounded power system for a oil well is provided which includes a power transformer above ground and a pump motor below ground. There is provided a signal system which includes a below ground sensor system and an above ground signal conditioning and monitoring unit where the sensor system utilizes the main power lines for carrying the sensor signals. A connectable high resistance grounding scheme is provided to the aforementioned floating system, so that in the event of a arcing ground fault or similar occurrence the system may be immediately grounded, thus compensating for the effects of the arcing ground fault and providing personnel safety and electrical equipment protection. When the high resistance grounding system is not utilized the aforementioned signals from the sensors are easily carried by the power conductors.

The invention relates to a temperature probe for an oven, comprising in one embodiment a longitudinal housing in the form of a spit. A temperature sensor and an electronic unit are arranged in a tip and are connected at the other end to emitting means. The temperature probe comprises a thermogenerator for producing energy. The thermogenerator uses a temperature difference between a higher temperature inside the oven and a lower core temperature in a food product, such as roast, in which the temperature probe is inserted, for producing energy for operating the emitting means.

A gas burner for a gas cooktop has a gas burner body with gas outlet openings. A thermogenerator is arranged above the gas burner body, advantageously arranged concentrically relative to said gas burner body and with the same shape and size, wherein the thermogenerator is heated by said gas burner body. The thermogenerator bears against a cooler pot base by way of its upper face. The thermogenerator generates electrical energy which is used to operate a control of the gas cooktop and which can be stored.

A sensor for a sensor device on a cooking hob is provided with contacts on a support, an electronic circuit for signal processing and a resistance track for temperature measurement. The sensor is arranged in a tubular metallic housing above a radiant heater of the cooking hob. The metallic housing is operated as an electromagnetic pan recognition sensor. The functions of temperature measurement and pan recognition can be combined in one sensor device as a module. A good transmission of sensor signals can be achieved as a result of the physical proximity of the sensor signal processor to the sensor by placing them on the same support.

An operating device for an electrical appliance has a control panel and an operating element for rotary actuation arranged thereon and a controller, wherein said operating element is mounted in a receptacle arranged behind said control panel and comprises on a front a touch-sensitive switch with a sensor element being connected electrically conductively to said controller. Said operating device comprises a retraction device for retracting said operating element into its recessed position in said receptacle by pressing. Said retraction device is configured in such a way that said knob can only be retracted into its recessed position in a single retraction rotational position, said touch-sensitive switch being deactivated by said controller in said retraction rotational position.

An operating device for an electric hob comprises a plurality of touch pads as touch points, in which operation takes place by applying a finger to specific defined touch points. The touch pads may be in themselves structurally movable separately of the electric hob or the operating device. The touch pads comprise individual coding circuits which can be accomplished by way of modulation of an electromagnetic field. The operating device has an electrode surface for attachment next to the electric appliance, on which the touch pads are arranged. Capacitive coupling is formed between the touch pads and the electrode surface. The operating device comprises a drive and evaluation device connected to the electrode surface both for detecting touching of a touch pad in general and for detecting and differentiating between touching of a specific touch pad and touching of another touch pad as indicated by the individual coding circuit.

A heater for a hob or cooktop having a glass ceramic surface is disclosed, whereby a number of individual modules with induction coils are provided with converters and a converter control for each induction coil. The modules may be independently assembler and/or replaced, and are arranged close together beneath the glass ceramic hob and electrically connected to a busbar. Each module may be controlled separately. A heated surface of using various combinations of modules can thus be achieved.
