Definitions

  • the present invention refers to a device and a method for washing laundry, in particular a washing machine or household washer-dryer.
  • Household washing machines and washer-dryers comprise a support and housing structure, inside which a washing tank is housed provided with a front opening that can be closed through a door with a window that is hinged at the front to the housing.
  • a basket for receiving the laundry that is to be washed and (in the case of the washer-dryer machine) that is to be dried is housed in a rotatable manner around a horizontal or inclined axis.
  • the basket defines a front opening arranged at the opening of the washing tank, so as to be able to carry out the loading and the unloading of the laundry.
  • the washing tank is suitable for containing the washing liquid during the steps of washing the laundry and for forming (in washer-dryer machines) a portion of the drying circuit during the drying step of the laundry.
  • a washing water loading system is foreseen that can be connected to the water mains.
  • a discharge duct is foreseen with associated discharge pump that provides for removing the washing liquid from the tank and that, together with the loading system, controls the level of liquid inside the tank.
  • an electric resistance arranged inside the tank in the gap between the wall of the tank and the laundry-holder basket.
  • the drying circuit of washer-dryer machines of the prior art typically comprises an extraction unit, a heat exchanger and a heating unit with electrical resistances communicating with one another by means of a drying duct.
  • the air flow caused by the extraction unit is heated by the electrical resistances and is conveyed into the basket, in which, passing through the wet laundry, causes the water contained in the fabrics to evaporate.
  • the moist air is cooled down by a spray of cold water. Due to the cooling, the vapour condenses and is collected and discharged together with the cooling water. The dehumidified air is then sucked up again by the extraction unit and is made to recirculate.
  • EP0771898A2 describes a washing machine in accordance with the preamble of claim 1.
  • Washing machines and washer-driers of the prior art and the washing and drying methods they implement are bulky and have high water, electric energy and detergent consumption, both in the washing step and in the drying step.
  • the main purpose of the present invention is therefore that of providing a wishing machine or washer-dryer, as well as a washing method having characteristics such as to reduce the consumption of water, detergent, additives and electric energy, for the same amount of washing and for the same washing results and (in the case of the washer-dryer machine) drying results, as well as not substantially increasing the bulk of the household appliance.
  • This and other purposes are achieved, with a washing machine in accordance with claim 1.
  • the formation of the recovery tank in the door it is possible to recover, hold and reuse a portion of the water already used previously inside a space which does not cause an increase in the overall bulk of the household appliance.
