A control unit for an electric household appliance for setting functions and operating parameters. The control unit includes at least one control knob located on a display panel by magnetic force. The control knob capable of being pushed by an operator from an initial position into a selecting position to select a function, such as a specific cooking plate and capable of being rotated about its axis to set an operating parameter of the function, such as the cooking temperature of the cooking plate.

Control unit for electric household appliance

A capacitive proximity and/or touch switch has an electrically conductive body bridging a spacing distance between an at least partially translucent, electrically insulating cover plate and a carrier plate. The electrically conductive body has a sensor surface at the end thereof facing the cover plate. The sensor surface is connected to an evaluation circuit via the electrically conductive body. A light source is associated with the sensor surface, the light of which implements an optical display in an operating region defined by the sensor surface at the front of the cover plate. The light source is disposed at an offset to the position of the operating region, and the electrically conductive body has a reflector region configured such that light emitted from the light source can be deflected in the direction of the operating region by the reflector region.

Capacitive proximity and/or touch switch

A capacitive proximity switch has an electrically conductive sensor surface, which is covered by an electrically non-conductive covering plate and which serves as a part of a capacitor with a capacitance that varies with proximity. The proximity switch includes a reference sensor surface for generating a reference signal for determining an actuation state of the proximity switch. Signal portions of the reference signal are proportional to the capacitance of a reference capacitor formed with the reference sensor surface, and the capacitance of the reference capacitor is determined by surrounding conditions of the sensor surface.

Capacitive proximity switch and household appliance equipped therewith

A capacitive proximity switch has an electrically conductive sensor surface, which is covered by an electrically non-conductive covering plate and which serves as a part of a capacitor with a capacitance that varies with proximity. A household appliance is equipped with a proximity switch of this type. The sensor surface has an active shielding, which is formed by a shielding surface to which a clock signal is applied at the same time as it is applied to the sensor surface.

The invention allows a user of a program-controlled household appliance to obtain comprehensive information concerning different working process parameters by having the appliance include a display device for acoustic signals or optical characters and a memory area of the program control device, which is configured for saving set program parameters and measurement and operational values of the actuators and sensors participating in the program that is running. For such a purpose, the display device contains a display element (field), which is activated upon completion of the working process and contains the comment 'Log', indicating the option of issuing information relating to measurement and operational values that have been saved prior to and/or during the last completed working process.
