The door closure is actively connected to the ventilation valve in such a manner that the actuator opens the ventilation valve when the door is released and closes the ventilation valve when the door is closed, so that the ventilation valve is closed when the door is closed during operation.

Abstract: The method according to the invention for sterilizing temperature-sensitive laundry items comprises the following steps: in the dry state, the laundry items are exposed to a process air flow having a defined temperature Tp and over a specified time period, then the laundry items heated in such a way are cooled to a target temperature Tptarget significantly lower than the temperature Tp, and then the cooled laundry items are washed in a washing process. The washing-drying unit according to the invention has a control device (CTRL) for carrying out said method.

Abstract: A washing machine includes a laundry drum which is rotatably mounted inside a tub. The tub is connected in a fixed manner within a surrounding housing. The axis of rotation of the laundry drum is variable in height with respect to the tub. Elastic elements are positioned outside the tub to suspend the laundry drum together with a drive unit within the housing in an oscillating manner. The presence of a relatively high water consumption of the washing machine can be avoided and the relative position of the laundry drum with respect to the tub can be adjusted by providing a position-adjusting device, by which the height and/or the angle of the axis of rotation can be adjusted within limits, and which engages with a part that is connected in a fixed manner to the bearing for the drive shaft of the laundry drum.

Abstract: A domestic appliance includes at least one component having a surface that can become laden with organic dirt. The surface includes a photocatalyst and is made from a primary-formed first material in which the photocatalyst is dispersed. A photoradiation source is provided for irradiating the photocatalyst with an activating electromagnetic radiation.

Abstract: The invention relates to a washing machine in which the supplementary ventilation line is connected to an opening as high as possible on the washing tub and running to a nozzle, arranged as high as possible on the detergent flushing device, by means of an additional ventilation system which provides a ventilation to prevent an accident with a stopped machine and a closed door. The detergent introduction line runs from the detergent flushing device to an inlet nozzle, placed as far as possible from the ventilation nozzle in the upper region of the washing tub, such that no reservoirs of water can form in the line. Both lines are connected to the atmosphere by means of the flushing device. According to the invention, the ventilation system provides an adequate supply of fresh air. Noise on operation of the washing machine is adequately damped and the foam and water vapor outlet can be as good as excluded.
