Estimating the term…
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 an electric appliance comprising an electric hob, an oven, or a vent hood, said operating device having defined touch points and configured to be operated by application of a finger to one of said defined touch points, wherein said operating device has a plurality of touch pads with sensors as said touch points, said touch pads being structurally freely movable from said electric appliance and said operating device, said touch pads comprising individual coding circuits, said operating device comprising an electrode surface or a coil positioned on or next to said electric appliance said touch pads on said electrode surface or said coil, wherein a capacitive or an electromagnetic coupling is formed between said touch pads and said electrode surface or said coil, and wherein said operating device comprises a drive and evaluation circuit connected to said electrode surface or said coil configured to detect touching of one of said touch pads.
An electric hob comprising an operating device, said operating device having defined touch points and configured to be operated by application of a finger to one of said defined touch points, wherein said operating device has a plurality of touch pads with sensors as said touch points, said touch pads being structurally freely movable from said electric hob and said operating device, said touch pads comprising individual coding circuits, said operating device comprising an electrode surface or a coil positioned on or next to said electric hob said touch pads on said electrode surface or said coil, wherein a capacitive or an electromagnetic coupling is formed between said touch pads and said electrode surface or said coil, and wherein said operating device comprises a drive and evaluation circuit connected to said electrode surface or said coil configured to detect touching of one of said touch pads, and
