Capacitative operating device for a domestic appliance, domestic appliance and method for operating a capacitative operating device in a domestic appliance

摘要

The device (1) has a control device (10) providing an input signal (UE) for a treatment circuitry (6). The control device recognizes operation of a capacitive touch sensor (2), a capacitive proximity sensor (3) and a capacitive sensor (4) and/or approximation to the sensors depending on an output signal (UA). A subtraction part (15) takes an amplitude portion (B) of amplitude (A) of the output signal and outputs a subtraction signal (US) as a result of subtraction. The control device detects the operation of the sensors and/or approximation to the sensors based on the subtraction signal. An independent claim is also included for a method for operating a capacitive operating device.
