Definitions

  • the invention relates to the field of laundry treatment machines, such as in particular tumble or combination devices, so-called washer-dryer, and relates to a filter assembly with a collecting container for receiving impurities separated from rinsing liquid and at least a first and at least one second inlet opening, through which the rinsing liquid into the collecting container can get.
  • the laundry treatment appliance is designed as a heat pump tumble dryer and has a laundry drum, in which laundry to be dried is overflowed by warm process air, which absorbs moisture from the laundry.
  • the process air leaving the laundry drum passes through a process air lint filter to a heat exchanger (evaporator), at which moisture condenses out of the process air and drips off as condensate into the filter arrangement arranged underneath.
  • the laundry to be dried during the drying process in addition to moisture and lint, hair, lint and the like from the process air, which are hereinafter referred to in the context of the present description generally as impurities.
  • rinsing liquid a liquid which may preferably be formed by the condensate and which is hereinafter generally referred to as rinsing liquid.
  • the rinsing liquid hits bubble-like on the components to be cleaned and rips the contaminants deposited there with.
  • the rinsing liquid then passes from the process air lint filter on the one hand or the heat exchanger on the other hand and thus in different ways to a first or a second inlet opening of the filter assembly.
  • the rinsing liquid enters through the first or the second feed opening into a collecting container of the filter arrangement, wherein the impurities are deposited in the collecting container through a lint filter (for example a sieve or fleece) and returned to the collecting container. to hold.
  • a lint filter for example a sieve or fleece
  • the filter arrangement or the lint filter is configured as a so-called life-time lint store and stores the impurities over the service life of the laundry treatment appliance.
  • the filter arrangement could also be made removable in such an arrangement, so that the collecting container can be emptied as needed.
  • the process air stream can also reach the collecting container via the first feed opening and flow out of the second feed opening (or vice versa).
  • the known filter arrangement forms at least for a portion of the process air flow a bypass path (also referred to as a bypass), can flow past the process air at its subsequent site of action, namely the heat exchanger. This reduces its cooling capacity and thus the energy efficiency of the laundry treatment machine.
  • DE 10 2009 046 921 A1 discloses a tumble dryer with a lint filter and with a cleaning device which optionally frees a first lint filter located in the process air stream or a heat sink (evaporator of a heat pump) from an impacting lint by surge-like application of a rinsing liquid.
  • the rinsing liquid then passes in both rinsing operations in a common container containing a filter bag.
  • an object of the present invention is to design a filter arrangement such that it does not impair the cooling performance of the process air stream flowing in the laundry treatment machine or only to a very small extent while maintaining the same performance.
  • the first and the second inlet opening lead to partial regions of the collecting container, which are fluid-tightly isolated from one another so that a process air flow between the first and the second inlet opening is prevented by the filter assembly therethrough.

Abstract

L'invention concerne un système de filtre pour une machine de traitement de linge comprenant un récipient collecteur (10) pour recevoir des impuretés (14) séparées du liquide de rinçage (7, 8) et au moins une première (2) et au moins une deuxième ouverture d'entrée (3a, 3b) par laquelle le liquide de rinçage (7, 8) peut parvenir dans le récipient collecteur (10). Pour réaliser un tel système de filtre de telle manière que, pour un rendement inchangé, il ne porte pas ou ne porte qu'extrêmement peu préjudice à la capacité de refroidissement du flux d'air de processus s'écoulant dans la machine de traitement de linge, la première (2) et la deuxième ouverture d'entrée (3a, 3b) conduisent à des régions partielles (12) du récipient collecteur (10), lesquelles sont isolées l'une de l'autre de manière étanche au fluide de sorte qu'un écoulement d'air de processus entre la première (2) et la deuxième ouverture d'entrée (3a, 3b) est empêché par le système de filtre.
