Problems solved by technology

[0004] However, a detrimental effect can occur due to the cleaning (or flushing) of the fluff sieve by means of condensate, since the openings of the fluff sieve are temporarily blocked by water, which in turn can mean such a high flow resistance that in the A sufficient drying air volume flow for a suitable drying function does not occur during the drying process
Such clogging of the fluff screen has a huge disadvantage for the performance of the laundry treatment appliance

Embodiment Construction

[0023] figure 1 A schematic sectional illustration of a section in the region of the base part 2 of the laundry treatment appliance 1 is shown for an exemplary embodiment of the laundry treatment appliance 1 according to the invention.

[0024] The laundry treatment appliance 1 has a closed drying air circuit 3 with an obliquely arranged fluff sieve 4 . Furthermore, the laundry treatment appliance 1 has a heat pump 5 thermally coupled to the drying air circuit 3 , for which heat pump 5 figure 1 Only the evaporator 6 and the liquefier 7 are shown.

[0025] Furthermore, the laundry treatment appliance 1 has a flushing device 8 for flushing particles from the fluff screen 4 , the evaporator 6 and the liquefier 7 . For this flushing device 8, in figure 1 Only the diffuser 9 for flushing the fluff screen 4 , the diffuser 10 for flushing the evaporator 6 and the diffuser 11 for flushing the liquefier 7 are shown in FIG. Furthermore, the flushing device 8 can be constructed conve...

Abstract

The invention relates to a laundry treatment appliance having a closed dry air circuit with a fluff screen, a heat pump, a flushing device for flushing particles out of the fluff screen and a heat pump evaporator, and at least one collection container for collecting particles flushed out of the fluff screen and / or the evaporator; the collection container has a first inlet opening through which particles flushed off from the fluff sieve reach the collection container and at least one second inlet opening through which particles flushed off from the evaporator reach the collection container. Inorder to improve the power and energy efficiency of the laundry treatment appliance, at least one air outlet opening separate from the inlet opening is formed in a wall section of the upper wall of the collection container facing the fluff screen, so that in the drying process, part of dry air flowing into the collecting container through the first inlet opening flows out of the collecting container towards the evaporator through the air outlet opening, the wall section is arranged on the bottom side below the area between the lower end of the fluff screen and the evaporator.

Description

technical field [0001] The invention relates to a laundry treatment appliance with a closed drying air circuit equipped with at least one fluff sieve, a heat pump thermally coupled to the drying air circuit, an evaporator for removing particles from the fluff sieve and the heat pump A flushing device for flushing off, and at least one collection container for collecting particles flushed off from the fluff screen and / or the evaporator, wherein the collection container has at least one first inlet opening and at least one second inlet opening, from Particles washed off from the fluff sieve pass through the first inlet opening into the collection container, while particles washed off from the evaporator pass through the second inlet opening into the collection container. Background technique [0002] During the drying process carried out by means of a laundry treatment appliance with a heat pump, drying air circulates in a closed drying air circuit, during which particles adhe...
