  • Publication number: 20040055186
    Abstract: To improve a smoothing effect on items of clothing by subjecting the items to moisture and heat and, thereby, relaxing the fabric of the clothing items to reduce creases, an apparatus and a method of smoothing includes subjecting the items of clothing, preferably, in a heated and moistened state, to at least one gas jet, in particular, a compressed air jet, which is not aligned parallel to the clothing item and which exerts a force on the clothing item. Advantageously, the clothing item is subjected to gas jets from both sides.

  • Patent number: 6698254
    Abstract: 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.

  • Publication number: 20040007029
    Abstract: 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.

  • Publication number: 20040000068
    Abstract: Instead of desiccating articles of clothing by spinning the articles, the method and apparatus according to the invention removes moisture from these articles by pressing or drying them with the aid of hot air. Desiccation of the clothing articles occurs gently and with a low expenditure of energy by subjecting the articles to the action of at least one gas jet and, in particular, of a compressed air jet, which is not aligned parallel to the surface of the article of clothing to exert a force upon the article. Advantageously, the article of clothing is subjected to the action of gas jets on both sides.

  • Publication number: 20040000174
    Abstract: A cupboard-like washing machine includes a conveyer belt for moving the item to be washed in a cycle during a drying process. The dryer can be embodied as an air circulation dryer or an air evacuation dryer. Moving the item to be washed using the conveyer belt reduced the drying time. A rinsing container that is disposed in the rear wall of the housing is used as a heat exchanger.

  • Publication number: 20040000175
    Abstract: A cabinet-shaped washing machine includes a conveyor belt to move laundry goods in circulation, with the laundry goods passing through various successive steps of the laundry cycle. Following the actual washing process, a downstream pre-dehumidification as well as a drying and pressing phase can be realized in the same housing.

  • Publication number: 20030233766
    Abstract: Examples of dehumidifying processes for clothes include spinning, extracting the moisture by pressure, or drying the clothes using heat and air. To dehumidify the clothes gently and economically in terms of energy consumption, a method and apparatus for dehumidifying clothes includes bringing the clothes into contact with at least one absorption body of an absorbent material. Advantageously, a rotating absorbent body is used, its sections being continuously alternately brought into contact with an item of clothing and dehumidified by pressing.

  • Patent number: 6378341
    Abstract: Detergent solution is discharged by means of a pump (10) at the bottom of a washing handling space (1) and is fed back to the handling space (1) via a pipeline (9) above the washing (3) located in the handling space. The washing machine is also connected to a fresh-water supply line (5) which can be opened and closed by a valve (7) which is controllable by a sensor device (12) suitable for establishing a volumetric flow present in the pumping direction of the pump (10). It is possible to dispense with a separate sensor element for controlling the fresh-water supply by a body (13) which can be actuated by the volumetric flow prevailing in the pipeline (9) being arranged along the pipeline (9) and, depending on the presence or absence of volumetric flow, protruding into or releasing the measuring section (18) of a turbidity sensor (17). Finally, the valve (7) is controlled by the turbidity sensor (17) so as to assume its opening or closed position.
