摘要： A capacitive proximity control device (28) for a domestic washing machine (10) or other domestic electrical appliance is proposed. In some embodiments, the proximity s control device comprises two planar sensor electrodes (34, 36) arranged on a door (20) of the washing machine at a spatial distance from one another. An electronic assembly is connected to the two sensor electrodes, which electronic assembly is adapted to generate, in association with each of the two sensor electrodes, an electrical sensor signal which is representative of a change in a capacitance associated with the sensor electrode in question. By mutual correlation of the two sensor signals, the electronic assembly is able to determine a proximity operation of the control device. A shielding electrode can be arranged in the spatial region between the two sensor electrodes.

摘要： A light sensor device is disclosed for installation in a heat-using domestic electrical appliance such as, for example, a washing machine or a dishwasher and permits the implementation of a touch-free operating function, for example an automatic door opening function. The light sensor device includes in some embodiments: a window element which is formed of light-permeable material and is arranged with space on a first window side for hand movements; a first light source arrangement arranged to radiate visible light into the window element; a second light source arrangement which is arranged to radiate infrared light through the window element from a second window side opposite the first window side; and a photodetector arrangement which is sensitive to infrared light of the second light source arrangement and is arranged on the second window side, for detecting infrared light which strikes the photodetector arrangement from the window element.
