A method for washing laundry in a program-controlled domestic laundry-care appliance including the steps of heating washing liquid present in the tub and heating the washing liquid to a specific washing temperature set as a function of determined parameter values that are specific to the laundry being washed and/or the appliance.

A method for determining a target rotational speed below an application rotational speed of a washing drum of a laundry treatment device having a drive and a vibrating system, wherein a dependence of a mechanical effect on items to be washed located in the washing drum on the respective nominal speed of the washing drum is used to ascertain the target rotational speed at which the mechanical effect is at the greatest. The mechanical effect at a respective target rotational speed is ascertained by measuring vibrating system movements of the vibrating system which exhibit greater frequency than the respective target rotational speed. The rotational speed at which the maximum vibrating system movement was measured is selected for carrying out the washing care procedure. The advantage of such a method is that the washing mechanics can be increased, thus improving the cleaning efficiency.

Method and device for determining the optimal rotational speed of a drum of a laundry treatment device

A method for accelerating the wetting of washing in the variable-speed drum of a drum washing machine. A quantity of fresh water is introduced according to the determined quantity of laundry. The drum is driven at intervals and in a reversing manner in successive phases for a first determined length of time at an rpm which is adapted to the washing. The drum is stopped and/or driven at an rpm adapted to the wetting of the washing for a second pre-determined length of time, such that the water is especially effectively distributed over the washing by means of ladling devices located on the drum. The required quantity of washing liquid for the following washing phase is determined once the drum is driven at intervals and in a reversing manner at an rpm adapted to the washing after the second pre-determined length of time has come to an end.

A washing machine with a controllable fresh water intake for at least two detergent chambers which are located inside a housing of a detergent flushing device and which have an outlet for water or the mixture of detergent and water which opens onto a bottom surface of the housing which is inclined towards an outlet connection for a detergent supply line to the tub of the washing machine in which a laundry drum is mounted at least approximately horizontally, the washing machine comprising partial surfaces into which the bottom surface of the housing is divided, the partial surfaces including inclinations differing from the horizontal, the inclinations being differently directed to at least one of the other partial surfaces and each partial surface is assigned to at least one detergent chamber and includes an outlet connection in a lowest region of the partial surface.

Washing machine comprising a controllable water supply and method for operating a washing machine of this type

A method for determining the water storage capacity of textiles, wherein the rinsing phase has at least one rinsing sequence which follows a drying sequence. The method is characterized in that a first water absorption is measured during the wetting phase and a second water absorption is measured during at least one of the rinsing sequences, in that the two water absorption measurements are compared with one another and the water storage capacity of the textiles is defined using the comparison.

A sensor for determining the level of the liquid in the lye container for removing foam in the lye container of a drum washing machine with a lye discharge system arranged on the floor of the lye container with a lye pump during a program step, which is provided for dehydrating the lye container. Its sensor signal P is recorded during operation of the lye pump. According to the present invention the sequence p/t of the sensor signal contains a component &#x394;p/&#x394;t, whereof the presence indicates the presence of foam in the measuring region. Further, in the presence of the component a foam treatment measure suiting the type of component is introduced.

A sensor system for a water-bearing domestic appliance for monitoring the treatment fluid in the appliance. The sensor system measures the treatment fluid parameters in a program sequence that includes alternating idle and in motion operations of the appliance. The measured treatment fluid parameters can be compared to known proper operational treatment fluid parameters.

Process for operating a water-bearing domestic appliance and domestic appliance for same

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.

Programmable household appliance with a display device

The fluid line between a drain opening at the bottom of the tub and an opening located at a higher level in the tub includes a line segment, which serves solely to keep the washwater in the tub in circulation between the upper opening and the drain opening. The line also has a solid pipe segment with a transparent region, at the wall of which a sensor is mounted that responds to the turbidity of the washwater. The sensor has an optical transmitter and an optical receiver. The sensor elements are built into a forked housing so as to securely mount and protect the sensor from the severe shaking during spin cycles. The forked housing embraces the pipe segment and the housing is adapted to the outer shape of the pipe segment at the faces which are in contact with the transparent region.

Drum-type washing machine with a multi-part fluid line

A washing machine includes a perforated washing drum with a contact rpm at which items of laundry in the washing drum come to rest against a surface of the washing drum due to centrifugal force. The washing drum is intermittently driven in alternating rotary directions (reversing mode) during washing and/or rinsing, for accelerating the washing drum in one of the rotary directions to a first rpm being markedly below the contact rpm and accelerating the washing drum in the other of the rotary directions to a second rpm being markedly above the contact rpm.
