  • a drying process carried out with a laundry treatment device with a heat pump in which drying air is circulated in a closed drying air circuit, particles adhering to the laundry to be dried, such as lint, are picked up and carried along by the drying air.
  • conventional laundry treatment devices are equipped with at least one so-called fluff filter to separate most of the particles from the drying air flow.
  • laundry treatment devices which have a rinsing device by means of which the lint filter can be automatically cleaned or rinsed using a condensate (water) that accumulates during the drying process.
  • a condensate water
  • Such a laundry treatment device can additionally have a collecting container for collecting the particles rinsed off from the lint filter.
  • DE 10 2008 041 998 A1 discloses a dryer with a drying chamber for receiving moist material and an essentially closed process air duct for circulating process air through the drying chamber.
  • the process air duct has a heat source for heating the process air before it enters the drying chamber, a heat sink for cooling the process air after it exits the drying chamber and a first lint filter arranged between the drying chamber and the heat sink for collecting lint from the process air, the a first cleaning device is assigned to the first lint filter.
  • the first cleaning device has a collector for a liquid, a first flushing line connected to the collector, a first control element located in this first flushing line, a first distributor connected to the first flushing line for distributing liquid conveyed through the first flushing line to the first lint filter and to the Receiving captured lint from the first lint filter and a first drainage line for draining the liquid with the captured lint from the first lint filter to the collector.
  • a laundry treatment device has a closed drying air circuit with at least one fluff filter, one thermally connected to the drying air circuit coupled heat pump, a rinsing device for rinsing particles from the lint filter and an evaporator of the heat pump and at least one collecting container for collecting particles that have been rinsed from the lint filter and / or the evaporator, the collecting container having at least one first inlet opening via the particles rinsed off by the lint filter get into the collecting container, and having at least one second inlet opening through which particles rinsed off by the evaporator get into the collecting container.
  • At least one air outlet opening is arranged separately from the inlet openings and is designed and arranged in such a way that part of a drying air flowing into the collecting container through the first inlet opening during a drying process is via the air outlet opening in Flows out of the collecting container in the direction of an evaporator, the wall section being arranged on the bottom side below an area between a lower end of the lint filter and the evaporator.
  • a further flow path for the drying air flowing through the drying air circuit during a drying process is provided via the additional air outlet opening of the collecting container, whereby the negative effect of a temporary clogging of the fluff filter with water of a rinsing process carried out with the rinsing device on the drying process is reduced.
  • an air output and a good drying operation can be guaranteed even better across all boundary conditions, whereby a shorter drying time and overall higher efficiency can be achieved.
  • the evaporator of the heat pump is supplied with drying air via the additional air outlet opening of the collecting container.
  • the laundry treatment device according to the invention or its collecting container can also have two or more corresponding air outlet openings.
  • the closed drying air circuit has a heat exchanger section in which the evaporator and a condenser of the heat pump are arranged, a container in which a laundry drum is rotatably arranged, and at least one fan for circulating the drying air during a drying process in the drying air circuit on.
  • the lint filter is arranged in a section of the drying air circuit via which drying air emerging from the container flows to the heat exchanger section.
  • the flushing device can be set up to flush the lint filter and the evaporator at the same time. Alternatively or additionally, the flushing device can be set up to flush the lint filter and the evaporator individually.
  • the collecting container can be removed from the laundry treatment device so that the collecting container can be cleaned separately by a user.
  • the laundry treatment device can be designed as a laundry dryer or washer dryer, for example.
  • the air outlet opening is arranged on a step of the upper wall of the collecting container.
  • a section of the upper wall arranged under the evaporator, on which the second inlet opening is formed is arranged lower than a section of the upper wall arranged under the lint filter, on which the first inlet opening is formed, the step being formed between these wall sections .
  • an opening plane of the air outlet opening is arranged inclined away from the evaporator.
  • the laundry treatment device has at least one filter screen which is arranged on the air outlet opening and extends at least over the entire air outlet opening.
  • the filter screen is arranged in such a way that it is equipped with a during a rinsing process by which the evaporator is rinsed Part of a rinsing liquid used for the rinsing process is rinsed. This means that the filter sieve requires little maintenance, as it is also cleaned automatically during an evaporator flushing process.
  • a mesh size of the filter screen is larger than a mesh size of the lint filter. This reliably prevents the filter screen from becoming clogged with the rinsing liquid. This configuration is possible in particular if the functional surface of the filter screen is relatively small compared to the functional surface of the lint filter, so that only a smaller drying air flow loaded with particles is passed through the filter screen.
  • the laundry treatment device has at least one closing element movably arranged on the air outlet opening, which completely closes the air outlet opening in a closed position and at least partially releases the air outlet opening in a release position.
  • the air outlet opening does not necessarily have to be equipped with a filter screen, since the closability of the air outlet opening means that no permanent drying air flow can flow through the air outlet opening and thus only a comparatively small amount of particles is guided through the air outlet opening onto the heat exchanger.
  • the closing element can be moved into the release position during a flushing process carried out with the flushing device.
  • the closing element can for example be designed as a flap or the like.
  • the laundry treatment device has at least one electrically controllable drive connected to the closing element.
  • the drive can have an electric motor and be connected to an electronic device of the laundry treatment device.
  • Fig. 1 shows a schematic sectional illustration of a section of an exemplary embodiment for a laundry treatment appliance 1 according to the invention in the area of a floor pan 2 of the laundry treatment appliance 1.
  • the laundry treatment device 1 has a closed drying air circuit 3 with an inclined lint filter 4. Furthermore, the laundry treatment appliance 1 has a heat pump 5 which is thermally coupled to the drying air circuit 3 and from which in FIG Fig. 1 only an evaporator 6 and a condenser 7 are shown.
  • the laundry treatment appliance 1 has a rinsing device 8 for rinsing off particles from the lint filter 4, the evaporator 6 and the condenser 7. From the flushing device 8 are in Fig. 1 only a diffuser 9 for rinsing the lint filter 4, a diffuser 10 for rinsing the evaporator 6 and a diffuser 11 for rinsing the condenser 7 are shown.
