OPERATING DEVICE FOR AN ELECTRICAL APPLIANCE AND OPERATING METHOD
First Claim
1. An operating device for an electrical appliance, wherein said operating device has a control panel, an operating element comprising a knob for operation by rotary actuation arranged on said control panel and a controller arranged behind said control panel, wherein a receptacle is arranged behind said control panel, said operating element mounted in said receptacle and comprising a touch-sensitive switch with a sensor element on a front of said knob, said touch-sensitive switch being electrically connected or in a manner capable of capacitive signal transmission with said controller, said operating device comprising a retraction device for retracting said operating element into a recessed position substantially in said receptacle in response to pressing said knob, wherein said retraction device is configured in such a way that said knob is retractable into said recessed position in only one retraction rotational position, wherein said touch-sensitive switch is configured to be deactivated by said controller in said retraction rotational position.

Abstract
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.

12. An operating method for operating an operating device for an electrical appliance, wherein said operating device has a control panel, an operating element comprising a knob for operation by rotary actuation arranged on said control panel and a controller arranged behind said control panel, wherein a receptacle is arranged behind said control panel, said operating element mounted in said receptacle and comprising a touch-sensitive switch with a sensor element on a front of said knob, said touch-sensitive switch being electrically connected or in a manner capable of capacitive signal transmission with said controller, said operating device comprising a retraction device for retracting said operating element into a recessed position substantially in said receptacle in response to pressing said knob, wherein said retraction device is configured in such a way that said knob is retractable into said recessed position in only one retraction rotational position, wherein said touch-sensitive switch is configured to be deactivated by said controller in said retraction rotational position comprising the steps of:
-
detecting a rotational position of said operating element using a controller; and deactivating said touch-sensitive switch in said retraction rotational position, wherein said rotational position is the only rotational position in which said operating element may be retracted into said recessed position in said receptacle.
