Embodiment Construction

[0025] exist figure 1 In addition to the filter device 1 , the only incomplete other parts of the laundry treatment machine are shown, that is to say in particular the narrowed guide channel 2 for the liquid 3 as a so-called wash water volume flow Impurities such as fluff, hair, fine hair and the like (collectively referred to below as impurities 4 ) are cleaned from the surface 5 of the stationary fluff filter 6 . The fluff filter 6 is located in a flow channel 7 (not shown in detail) for so-called process air 8 which, in a known manner, previously flows through a drying chamber (not shown here) and is placed here in the drying chamber. The laundry in the compartment draws out moisture. In this case, the fluff filter 6 is provided with a heat outlet (also not shown here) arranged in the drying chamber and generally downstream of the process air flow. In principle, such a design of a laundry machine is known, for example, from DE 10 2009 046 921 A1.

Abstract

The filter system comprises a filter device (26) for filtering off impurities (4) carried by a liquid (3) that flows through a laundry treatment machine, and a receiving chamber (20) for the deposition of impurities (4) that are filtered off, said receiving chamber comprising at least one passage region (24) with a plurality of through-openings (28, 29, 30, 31, 32) for the liquid (3). The aim of the invention is to provide a filter system which has a receiving chamber for receiving impurities to be deposited that can be filled in a structured and reproducible way and is thus optimally utilized. The through-openings (28, 29, 30, 31, 32) in the passage region (24) are arranged and / or dimensioned such as to result in a throughput gradient (38) over the passage region (24), the flowing liquid (3) thus flowing through the receiving chamber (20) in a defined manner such that the receiving chamber (20) is filled and the impurities (4) are deposited in a preferred direction (40).

Description

technical field [0001] The invention relates to the field of laundry treatment machines, such as in particular clothes dryers, washer-dryers and / or washing machines, and to a filter device for a laundry treatment machine with a filter for filtering out Filtering device for impurities carried by the liquid flowing in the machine and a receiving space for depositing the filtered out impurities, the receiving space has at least one flow-through area with a plurality of flow-through openings for the liquid. Background technique [0002] Such filter devices are known for various purposes, in particular for the filtration or removal of hair, fine hairs and fluff (referred to below collectively or in general as impurities) and in various configurations. [0003] Therefore, documents JP-2010-005247-A and JP-2010-057651-A respectively disclose a washing machine with an external lint filtering device, the lint filtering device has an integrally formed separation device and a filter sc...
