摘要:
A control device for converting a control movement along a control path into a control signal has the control path corresponding to different control stages or control types. The control device has two measuring tracks with a linearly changing resistance associated with each track. In one embodiment, these measuring tracks are positioned concentric to each other in a semicircle. A voltage U, which is tapped via two opposite interconnected sliders, is applied to both measuring tracks at a junction point while the other junction point is connected to ground. If the detected values of the tapped voltages deviate from a corresponding stored value or pairs of values, there must be a fault, due to, for example a broken slider. This makes it possible to perform a test for determining the fault or a malfunctioning control device.

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.

An operator control device for functional adjustment of a functional device includes an operator control knob which has an off position in which the operator control device is deactivated. Said knob can be brought into a working position for functional adjustment purposes. The working position is predetermined by a lock-in position, and, starting from the working position, the operator control knob can be pulled out of the operator control device or pressed into the operator control device against a counterforce which increases as the distance from the working position increases. Here, the operator control device includes a movement detection means for detecting movement of the operator control knob out of the working position in one direction or in the other direction. The movement detection means is connected to a controller of the operator control device so as to carry out functional adjustment in a manner dependent on the detected movement.

In a hob (11), an operating toggle placed on a front panel (17) has on a connected power control device an actuator (23) for producing a haptic acknowledgement or response in the case of operation. The operating toggle (19) also has a proximity sensor (27). If a hand (29) approaches the operating toggle (19) for operation, this is detected by the proximity sensor and it brings the actuator (23) from a current-economizing standby mode into a normal mode, where it operates normally. If the hand (29) is removed again, it is again brought into the standby mode.

A holding device for an operator control on a front cover of an electrical appliance is designed for attachment to the front cover and has a feedthrough for a rotating shaft of a rotary encoder of the operator control. The holding device is embodied in an annular fashion around the feedthrough and has a front cover attachment part as well as a lighting ring part which is fitted onto the front of the front cover attachment part. The lighting ring part essentially covers the front cover attachment part toward the front, wherein the two parts have a circular-ring-like intermediate space between them, in which intermediate space at least one component carrier, which has a plurality of LEDs on the side toward the front cover attachment part, is arranged.

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.

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.

The invention relates to an operating device for a stove top, the device comprising rotary operating parts that are rotatably mounted in a base. The parts have a protruding region as a signal means, the region rotating in a plane of the stove top or a stove top plate when the rotary operating part rotates. In said plane, the stove top has a distance sensor, which can detect the rotation of the protruding region by means of the variable distance and evaluate the same as a rotational actuation or rotational movement for operating the stove top.

In the case of a method for operating a cooking point with a gas burner of a gas hob in which a pan detection is provided for switching off the gas burner when the pan is removed, the pan detection can detect the re-placement of a removed pan onto the cooking point. It then brings about a further operation of the gas burner by igniting the gas burner. When the gas burner is ignited after re-placement of the pan, a power level originally set for the gas burner is only achieved to the full extent with a time delay.
