  • the fluff filter 36 and/or the described washing mechanism are adapted to also remove larger fluff components so that the filter arrangement 10 is not needed.
  • Such a design is particularly beneficial as it does not need cleaning of the filter arrangement by the user, it is simpler, and/or reduces production and/or operating costs of the laundry treatment apparatus.
  • the filter arrangement 10 is not shown in the embodiment depicted by the following figures.
  • a fixed or removable grill is positioned at the opening to the process air channel arranged at the frame at the loading opening 6. The grill prevents laundry and foreign objects to fall into the process air channel and eventually reaching at the washing liquid collector.

  • the condensate sink is the washing liquid collector 34 (as in the embodiment shown in Fig.
  • a liquid conduit 58 connects an outlet of the condensate directing means 54 to the condensate sink, here the washing liquid collector 34.
  • a siphon 58a may be arranged in the liquid conduit 58 in order to prevent an air flow through the conduit 58caused by a pressure difference between the two ends of the conduit and/or to stop the condensate flow from the condensate collector 32 through the condensate directing means 54 and the conduit 58 to the condensate sink when the condensate pump is inactive.
  • the condensate directing means is designed to fluidly seal off the inlet of the condensate directing means 54 from the outlet directing condensate to the conduit 66. I.e. in its default or non-activated position the condensate directing means 54 seals off the passage towards the conduit 66.

  • the laundry treatment apparatus may comprise a direct condensate overflow 33 as shown in Fig. 3 for draining excess condensate from the condensate collector 32 to the washing liquid collector 34.
  • the condensate overflow 33 comprises a siphon (not shown), e.g. for compensating pressure differences between the condensate collector 32 and the washing liquid collector 34.
  • the condensate overflow allows excess condensate in the condensate collector to pass from the condensate collector to the washing liquid collector.
  • Allowing excess condensate to leave the condensate collector and pass to the washing liquid collector helps to reduce operating noise of the laundry treatment apparatus, because the condensate pump does not need to be activated even when the condensate collector is full. Moreover no fluff filter washing for removing the condensate from condensate collector 32 is required when there is excessive condensate and no need for filter washing.
  • the fluff filter 36 is washed before it is clogged by fluff transported in the process air flow.
  • the fluff filter 36 is washed at the beginning or at the end of a laundry treatment program or sub-program. More preferably, washing the fluff filter 36 is avoided during an ongoing or running laundry treatment program or sub-program that requires drying of the process air flow, because washing the fluff filter 36 wets the filter whereby extra humidity is added to the process air A passing through it.
  • incorporating a condensate directing means 54 and/or a condensate overflow 33 is particularly beneficial because it enables draining or partial draining of the condensate collector 32 when the condensate collector is full without the need of conveying condensate to (i.e. washing) the fluff filter 36.
  • a siphon 58a is preferably arranged in the conduit 58 in order to compensate pressure differences between the condensate collector 32 and the removable tank 12 and/or the overflow passage 76 and/or in order to interrupt liquid flow from the condensate collector 32 to the removable tank and/or the overflow passage 76 when the condensate pump 72 is stopped.
