  • the operation of this filter device 1c will be described below in the Fig.5A and Fig.5B described in more detail, wherein 5A the filter device 1 c in a filter position shows and FIG.5B shows the filter device 1c in a self-cleaning position.
  • the sequence 3 is open (eg, characterized in that the shut-off valve VE2 in Fig.1 is open), so that condensate K flows up through the inlet 2 in the first chamber part 5a, for example pumped up by the pump P. Due to the large cross-section of the first start-up 3, a high volume flow and a high flow velocity are formed.
  • the flow body 12 is arranged in the flow, which is supported by the opposite arrangement of the inlet 2 and the second outlet 4 and a small distance of the associated orifices in the first chamber part 5a. The flow body 12 can be pressed in the flow conditions of the filter position in the flow direction against gravity close to the nozzle 7. As a result, the second sequence 4 is shut off.
  • the liquid for example in the form of condensate water K, flows around the flow body 12 through the filter element 6 into the second chamber part 5b and further through the first drain 3, for example to the washing container SB.
  • the flow body 12 thus forms together with the nozzle 7 thus a flow-dependent 'passive' shut-off valve.
  • the first drain 3 is shut off, e.g. by closing the shut-off valve VE2, and again condensate water K pumped through the inlet 2.
  • the cross-section of the second drain 4 is too small to allow a flow to be established which is sufficient to be able to press the flow element 12 sealingly onto the nozzle 7 again. Rather, the nozzle 7 remains open towards the first chamber part 5a, so that now the condensate water K displaced with the cleaned fluff can run off unfiltered through the second outlet 4 and can be removed, e.g. into the sewer AW or back into the condensate water tank KW.
  • this filter container 1 c can thus be achieved by a choice of a cross section of the respective processes 3 and 4, a cross section of the downstream flow channels SL (hose, pipe, etc.), a flow channel length of the downstream flow channels SL and / or a delivery height that clearly distinguish a volume flow in the filter position and a volume flow in the self-cleaning position.
  • This asymmetry in the volume flows causes the movably mounted flow body 12 to close the second outlet 4 in the filter position and can not close it in the self-cleaning position.
  • Such a switching characteristic may e.g. be adjusted by fixing the mass of the flow body with.
  • the filter container or the filter device e.g. a dishwasher
  • the impurities may then be, for example, leftovers.
  • a shut-off of a drain or an associated flow channel can be carried out by means of at least one valve.
  • the at least one valve may be part of the filter container and / or may be part of the filter device connected to the filter container.
  • the processes or the associated flow channels can be shut off individually or by means of one or more common valves.
  • the first sequence can be used to provide a useful liquid, which in particular can be a rinsing liquid.
  • a useful liquid which in particular can be a rinsing liquid.
  • a washing for example, can be dispensed with a washing.
  • the operations are not limited to a rectangular arrangement, but may also result in other suitable angles to each other in the chamber.
