Abstract: In a method for applying a treatment composition to a laundry item in a laundry treatment device having a rotatably mounted drum and a water supply, water is added to the laundry item in a first rotation step of the drum to set a pre-determined residual moisture content. A treatment composition is sprayed onto the laundry item with the aid of the water supply in a second rotation step of the drum, when the drum is rotated at a rotary speed which is equal to or greater than a centrifugal adhesion rotary speed.

Abstract: A water-conducting domestic appliance includes a housing having an interior, and a door which is connected to the housing to provide access to a treatment region in the interior of the housing. A ventilation valve controls ventilation of the treatment region of the housing. A door closure is provided to close the door and has an actuator which is connected to the ventilation valve. 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: A household appliance includes a container for receiving objects to be treated, an ozone generator having an intake air conduit, and an ozone eliminating device arranged in an exhaust air conduit. The exhaust air conduit is connected to the container and includes a fan for removing exhaust air from the container. The exhaust air conduit is connected to the intake air conduit of the ozone generator.

Abstract: A method for creating a hydrophobic effect of textiles in a washing machine. Hydrophobic agents dissolved in the washing liquid are contacted with the textiles during a treatment process. The tub is filled with an amount of water which is proportioned and which is heated to a minimum temperature in the tub while the textiles are soaked. The hydrophobic agent is flushed from the detergent storage chamber into the lye container by means of water and forms a washing liquid along with the water. The textiles are contacted with the washing liquid and are treated for a maximum of 30 minutes. The washing liquid is removed from the textiles and the washing liquid container by spin-drying without rinsing.

Abstract: A lint filter device for an airflow in a tumble dryer, comprising an endlessly circulating element, arranged around at least two deflector elements and positioned such as to be crossed by the airflow. The circulating element has an upper edge and a lower edge and first engaging elements are arranged on at least one of the two edges which, on opening a loading door of the tumble dryer may come to cooperate with at least one second engaging element, arranged inside the tumble dryer such that, on the opening process of the loading door, the circulating element may be automatically moved in a circulating direction and may be passed across at least one device for the removal of lint from the circulating element. The invention further relates to a method for cleaning such a lint filter device.

Abstract: A method for spin-drying textiles being subjected to a method for the production of a hydrophobic effect in a washing machine. Textiles located within the drum are brought into contact with hydrophobing substances dissolved in the washing liquid. The drum is accelerated for a first number of spin pulses to reach a speed in a first spinning block when the washing liquid is removed from the outer tub, the speed being below a critical speed of rotation. The drum is accelerated in a second spinning block for a second number of spin pulses to reach a speed that is above the critical speed of rotation. The drum is accelerated in a third and final spinning block for a third number of spinning pulses to reach a maximum speed of rotation that is compatible with the washing.

Abstract: A method for cleaning and restoring a hydrophobic effect of textiles in a domestic washing machine in which hydrophobic substances dissolved in the washing liquid are contacted with the textiles during a treatment process. A washing process for cleaning the textiles while adding a special detergent is carried out in the presence of an inflow of fresh water, and at the end thereof, the used washing liquid is pumped off. The soapy water used for the preceding process is replaced and a multi-stage rinsing process is carried out for the textiles. After termination of the rinsing process, the last rinsing water is replaced and the hydrophobic substances are added to a newly supplied amount of fresh water, and a treatment process for waterproofing the textiles is carried out in an additive-containing washing liquid and the used additive-containing washing liquid is removed without repeating the rinsing process.
