Definitions

  • the invention relates to a household appliance and to a method for manufacturing such a household appliances.
  • Household appliance are, for example, refrigerators, cooling appliances, as well as laundry treatment machines, both "simple” laundry washing machines (i.e. laundry washing machines which can only wash and rinse laundry) and laundry washing-drying machines (i.e. laundry washing machines which can also dry laundry), or drying machines (i.e. drying machines which can dry laundry).
  • laundry washing machines i.e. laundry washing machines which can only wash and rinse laundry
  • laundry washing-drying machines i.e. laundry washing machines which can also dry laundry
  • drying machines i.e. drying machines which can dry laundry.
  • Washing machines in households also called domestic washing machines, are well-known and usually are used for washing laundry.
  • Washing machines usually comprise washing tubs in which a rotatable drum is housed for receiving goods to be washed, usually laundry.
  • Washing liquid is introduced into the washing tub, which washing liquid consists only of water or mainly of water and detergents or washing or cleaning agents added to or dissolved in the water for improving the washing quality.
  • Laundry treatment appliance will refer to simple laundry washing machines, laundry washing-drying machines or drying machines.
  • Laundry treatment appliances such as washing or washing drying machines generally comprise an external casing provided with a washing tub which contains a rotatable perforated drum where the laundry is placed. A loading/unloading door ensures access to the drum.
  • Laundry treatment appliances typically comprise a water supply unit and a products supply unit, preferably a drawer, for the introduction of water and washing/rinsing products (i.e. detergent, softener, rinse conditioner, etc.) into the tub.
  • Known laundry treatment appliances are also provided with water draining devices that may operate during different phases of the washing program to drain the dirty water.
  • a complete laundry treating program typically includes different phases during which the laundry to be washed is subjected to adequate treatments.
  • a treating cycle usually comprises a main washing phase during which the laundry is treated by means of water and a detergent.
  • the water is typically heated to a predetermined temperature based on the washing program selected by the user. It is also possible that hot water is introduced into the tub from the hot water mains.
  • the drum is rotated, so as to apply also a mechanical cleaning action on the laundry.
  • the drum is typically rotated at high rotational speed, so in such a way that dirty washing liquid (i.e. water mixed with detergent) is extracted from the laundry, and this dirty washing liquid is drained to the outside by the water draining devices.
  • a draining device is arranged for draining the washing liquid from the tub in order to either feed back the washing liquid into the washing tub again, often being heated by a heating element arranged in or near the tub bottom, in a closed circuit or circulation mode or to drain the washing liquid out of the washing machine into a sewage conduit, in an open circuit, when it is not needed any more.
  • the washing tub has a sump at the tub bottom which is in fluid connection to the draining device.
  • a water level detector is often provided to detect the water level in the drum. The water level detector is typically realized by means of an air chamber connected to a pipe.
  • a filter is usually provided between a tub outlet and a draining hose which is configured to transport washing liquid or water to the outside of the appliance. The filter removes fluff and dirt and contaminating particles from the water / washing liquid and holds them within the filter housing.
  • the aim of the invention is to provide a household appliance in which components needed for allowing draining and filter washing liquid from the tub are convenient to install and replace.
  • the invention in a first aspect, relates to a household appliance, comprising a casing in which a tub is arranged, further comprising a drum rotatable mounted in the tub, further comprising a tub outlet through which washing liquid can be drained from the tub, further comprising an air chamber which is suitable to be associated to water level sensor for measuring the level of said washing liquid in said tub, further comprising a drain hose for draining washing liquid to the outside of said appliance, with a filter assembly comprising: an assembly housing, a tub inlet fluidly connected/connectable to the tub outlet, an air chamber inlet fluidly connected/connectable to the air chamber, a drain outlet fluidly connected/connectable to the drain hose, a filter and a pump, whereby the assembly housing is configured to receive the filter and to get connected to said pump.
  • the invention is based on the consideration that the functionalities of draining washing liquid from the tub if needed and filtering the washing liquid are performed in essentially the spatial same region of the appliance. In this region, a pump, a filter, a connection to an air chamber, a connection to a drain hose and a connection to the tub outlet need to be installed.
  • a pump, a filter, a connection to an air chamber, a connection to a drain hose and a connection to the tub outlet need to be installed.
  • the assembly of all these components and their spatial arrangement with respect to each other can lead to difficulties of their installation and maintenance and an exchange of components can get cumbersome.
