Also provided is an elastically deformable seal, which, is connected, on the one hand to the housing and, on the other, to the container. In addition, a dispenser housing with a filling connector is arranged in the housing. The seal has on a tubular projection an opening with one end of the filling connector being inserted into the seal at the opening of the seal.

Laundry handling apparatus with a cuff and a filling support

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.

A machine for laundry has a drum shaft rotatably mounted by a bearing for driving a laundry drum and having a device for determining loading-relevant characteristic variables or an unbalance of the laundry drum or of the drum shaft. The device for determining loading-relevant characteristic variables or an unbalance includes a magnetic field sensor that senses a magnetized region on the drum shaft or the laundry drum.

Machine for washing and/or drying laundry

A flush-in device is provided for a washing machine and has at least one flushable chamber open at the top. In order that, during flushing, liquid does not easily enter into an outer area of the flush-in device as a result, for example, of leakage and/or water of condensation and in order to simplify the construction of the flush-in device, especially in a sealing area and to reduce assembly expenditure, at least one annular channel at least partially surrounding the upper opening of the flushable chamber is provided and any liquid which has already penetrated into the annular channel can be led away via this channel.

A method and a device are provided whereby a container can be continuously filled with mixed water from separate cold and hot water pipes K, W within a short time and the temperature T of the mixed water is kept as constant as possible at a predetermined value Tduring the supply process. According to the method according to the invention, the regulating process always takes place only in one direction from higher to lower temperature values. The method is implemented by a regulatortowith separate intake pipes K and W for cold and hot water and a mechanical control elementwhich is only moved in one direction. The essential advantage of the method according to the invention is that it can be implemented very cheaply, especially a synchronous motor without reversal of the direction of rotation can be used as a drive for the control member. Possible perturbations in the hot water system can by intercepted to a sufficient extent by compensation which is easy to implement.

The shaft axis of a detergent-solution pump in a washing machine is pivoted about a vertical such that, as seen in the forward direction, it forms an acute angle &#x3b1; with a perpendicular center plane running from the front surface to the rear wall of the machine housing. The drain connector for the drain hose from the tub to the pump is oriented on the tub casing with an angular offset in the preferred spinning direction of rotation in relation to the vertical plane running through the drum axis. These measures give rise to better accessibility to the pump chamber and to improved pumping capacity, in particular for foam/water mixtures. The pump-out operation is shortened, and the overall height of the pump-out system can be reduced.

In household appliances with a safety hose, the stop valve and the control valve are hydraulically connected in series. It is thus impossible, or very difficult, for the user to detect when one of the valves is operating erroneously and not closing completely. The functioning of the control valve and of the stop valve is checked each time the household appliance is used. For this purpose, the valves and are alternately opened and closed in a selected phase during operation, or are opened and closed one after the other. The change over time in the measured values is recorded and evaluated in a suitable manner at a pressure sensor and/or at a throughflow meter. On account of the multiple use of the measuring sensors that are present, the cost of implementing the method is restricted to expanding the control system software.

A washing machine has a laundry drum and a tub and defines an outflow orifice at a lowest point and a second orifice at a point higher. An outflow line fluidically connects to the outflow orifice. A liquid line fluidically connects the outflow line to the second orifice. A turbidity sensor is disposed at the liquid line and responds to a turbidity of liquid flowing therethrough. A pressure controller includes a pressure line connection at the outflow line, a pressure sensor connected to the pressure line connection, a pressure of liquid in the outflow line dependent on a level of liquid in the tub being transmitted from the outflow line to the pressure sensor through the pressure line connection, and the pressure sensor responding to the liquid pressure and controlling a liquid filling level in the tub dependent upon the liquid pressure. In the configuration, the outflow hose has both a connection for a turbidity sensor and a connection for a pressure sensor.

Usually disposed in the top region of a household laundry machine is a drawer that is intended for accommodating detergents or condensate and is connected to a three-dimensional grip plate at the front. During operation of the machine, the grip plate is inserted in a recess of an operating panel, which is disposed at least more or less flush with the surface of the front side of the machine. For childproof locking, a latching edge is provided on the frame of the recess, and a catch, which is retained in the latching position by a spring, is disposed in the rear cavity of the grip plate. By virtue of an arresting device, the catch can be retained outside the latching position if an arresting slide is located in an arresting position.

Household machine for washing or drying laundry

A water-feed configuration for household appliances includes a hot-water hose and a cold-water hose connected to a single water inlet of the household appliance through a branching section

Water-feed configuration for household appliances

An automatically controlled washing machine includes a washing liquid circulation system which drains washing liquid from the bottom of a laundry treatment space and, via a supply orifice, supplies the washing liquid again to the laundry treatment space. The supply orifice is configured such that a dynamic pressure is present in the circulating line during a pumping operation. The washing liquid circulation system has a sensor device which is sensitive to the dynamic pressure and transmits a signal for controlling a supply valve for fresh water as a function of the dynamic pressure. The sensor device also detects a static pressure present in the laundry treatment space and in the circulating line, when the circulating pump is switched off. The sensor device transmits a signal for executing safety measures when the static pressure exceeds a given safety level so that the washing machine is protected against overflowing.
