Abstract: The invention relates to a mixing apparatus (1) with a main line (3), in which a liquid (F) flows along a direction of flow (FR), and a secondary line (9). The main line (3) has an inlet (4), an outlet (5) for discharging the liquid (F) conducted through the main line (3), and a three-way valve (8) at a beginning (6) and at an end (7). The secondary line (9) is connected via the three-way valves (8) to the main line (3) and, together with the main line (3), forms a mixing circuit (MKL). The liquid (F) can be pumped with a pump (11) through the main line (3) and through the secondary line (9) in the mixing circuit (MKL). In addition, at least one additive inlet opening (26) is provided on the main line (3) for adding an additive into a mixing zone (M) of the main line (3). The mixing apparatus (1) furthermore has at least one swirling means (13) in the main line (3). The invention moreover relates to a washing machine having such a mixing apparatus (1) and to a method for intermixing an additive with a liquid (F).

Abstract: In a method for operating a washing machine, a defined degree of wetting of items of laundry in the drum is required. This degree is brought about in determinable manner by alternately wetting the items of laundry in the drum from below and from above. At intervals, the items of laundry can be tumbled together or loosened up by rotation of the drum. The volume of water absorbed by the items of laundry can be determined by determining the total volume of water admitted into the washing machine and making a comparison with the volume of water not absorbed by the items of laundry. This absorbed water is assumed to be uniformly distributed within the items of laundry and a level of drenching or degree of wetting of the items of laundry can accordingly be determined. In this way, subsequent washing processes can be carried out in a more defined and overall better way.

Abstract: A detergent dispenser for a washing machine, in which laundry detergents and additives are mixed with water and conveyed onward into a drum of the washing machine, has a receptacle with a plurality of receiving chambers as a pull-out drawer. A first receiving chamber has a chamber outlet at the bottom and is open at the top, wherein the other receiving chambers are closed at the bottom and open at the top. A planar dispenser cover is arranged above the receptacle and has an internal volume with water channels separate from one another therein. A plurality of water channels are routed to a lateral outer side of the dispenser cover where they form channel openings, wherein a plurality of water channels are brought together in the dispenser cover. A water drain channel has an outlet opening above the first receiving chamber. Metering pumps are arranged at the channel openings on the lateral outer side. A water supply channel leads from this channel opening to a receiving chamber closed at the bottom, wherein the water drain channel in the dispenser cover leads from a channel opening to the metering pump into the first receiving chamber.

Abstract: A hydraulic device has rotatable hydraulic means such as a valve actuator or a peristaltic pump, an electric motor as a drive unit, and a gear unit between the drive unit and the hydraulic means, wherein the hydraulic means has at least two water-using ports. In accordance with the invention, the drive unit, the hydraulic means and the gear unit are designed as single function units and are detachably connected to one another as a complete function unit in the form of the hydraulic device. The detachable connection is advantageously achieved by means of screws.

Abstract: In a method for operating a washing machine with a drum, a drive motor for the drum, a power supply for the drive motor and a washing machine control monitoring and detecting the motor current by means of the power supply, the following steps are performed where the motor current is constantly monitored while the drum rotates for at least three full revolutions. A full revolution of the drum is divided into three rotation sections of equal size, and the motor current is monitored and recorded for each of the rotation sections. An envelope curve of this motor current is calculated, and therefrom the standard deviation is calculated. The standard deviation is divided by the mean value of the envelope curve to determine the coefficient of variation for each rotation section. By comparing the determined coefficient of variation for each rotation section with stored values for the coefficient of variation, the behaviour of the laundry items is determined as to whether laundry items slide down the drum inner wall, fall from the drum inner wall or rotate together with the drum. From this behaviour, parameters are determined for a further operation of the washing machine with regard to the treatment of the laundry items.

Abstract: The invention relates to a dispensing apparatus for adding additives for a washing machine and to a washing machine with such a dispensing apparatus. The dispensing apparatus has a main line along which liquid flows in a direction of flow with an inlet and an outlet. The dispensing apparatus has at least one arcuate line, wherein the arcuate line departs from the main line at an inlet opening and rejoins the main line at an outlet opening. The arcuate line is longer than the main line between the inlet opening and the outlet opening. At least one controllable dispensing device is provided on each arcuate line, which dispensing device is fluidically connected via a dispensing line to the arcuate line and via a supply line to a tank for additives.
