Definitions

  • the document DE 10 2013 225 532 B3 discloses a laundry treatment machine which has an internal cleaning device for the washing suds used for washing laundry.
  • An axially circumferential channel is provided in the suds container, to which the cleaning device is connected.
  • the drum has structures on the outside and reaching into the channel, which, when the drum rotates, convey the wash liquor into the channel and to the cleaning device.
  • This laundry treatment machine also has a collection arrangement mounted on the tub and protruding into the gap for collecting a film of liquid flowing on the tub in an approximately tangential flow direction, a discharge channel connected to the collection arrangement for discharging process liquid collected by the collection arrangement, and a second discharge channel connected to the discharge channel Injector for introducing the discharged process liquid into the interior.
  • the invention can be used in any type of laundry treatment machine which has at least one rotatable drum for the items of laundry to be treated, since the effort required to use the invention is very low.
  • the washer-dryer can also be considered. It is not important how the axis of rotation of the drum is oriented in space as intended.
  • the axis of rotation can be oriented essentially horizontally, as described in detail below, but it can also be oriented vertically or at any angle to the vertical.

    un dispositif d'admission (12, 13, 14, 15) pour faire entrer le liquide de traitement dans la cuve de lavage (3), qui comprend un premier injecteur (15) pour introduire du liquide de traitement directement dans l'espace intérieur (6), et
    un dispositif d'évacuation (16, 17, 18) pour évacuer le liquide de traitement hors de la cuve de lavage (3),
    caractérisé par
    un dispositif de collecte (21) monté sur la cuve de lavage (3) et faisant saillie dans l'interstice (10) pour recueillir un film de liquide (22) s'écoulant sur la cuve de lavage (3) dans une direction d'écoulement sensiblement tangentielle,
    un canal de dérivation (23) raccordé au dispositif de collecte (21) pour évacuer le liquide de traitement recueilli par le dispositif de collecte (21), et
    un deuxième injecteur (24) raccordé au canal de dérivation (23) pour introduire le liquide de traitement évacué dans l'espace intérieur (6).
  2. Appareil de traitement du linge (1) selon la revendication 1, dans lequel la cuve de lavage (3) est reliée à la carrosserie (2) par l'intermédiaire d'une manchette mobile (19) et peut être fermée par une porte (20) et dans lequel le deuxième injecteur (24) est disposé dans la manchette (19).
  3. Appareil de traitement du linge (1) selon l'une des revendications précédentes, dans lequel le canal de dérivation (23) est raccordé au dispositif de collecte (21) approximativement au milieu de la cuve de lavage (3) par rapport à l'axe de rotation (5).
