Definitions

  • the invention relates to a household appliance for treating laundry.
  • Household appliances for treating laundry use filter units that serve to filter fluids.
  • This fluid can be a water-soap mixture, as is used in washing machines, dishwashers and/or washer-dryers, for example, or it can consist of steam or process air, as is used in dryers and/or washer-dryers, for example.
  • dirt particles get into the respective fluid during a cleaning or drying process, also called a cleaning or drying process.
  • the dirt particles can include food scraps, hair, grease, sand, fibers from laundry items, microplastic particles and/or dust or dirt particles.
  • dirt particles are filtered out of the respective process by a filter unit during and/or after the cleaning or drying process.
  • a filter unit during and/or after the cleaning or drying process, one and/or more pumping processes can be carried out in which the fluid is pumped around, cleaned of dirt particles and fed back into the cleaning or drying process.
  • the so-called residual fluid remains, which is rich in dirt particles.
  • This residual fluid is usually no longer required and is pumped out of the household appliance and fed into a sink or drain line. Before being fed into the sink, the fluid is passed through the filter unit again, which means that fewer or almost no dirt particles get into the waste water or sewage system.
  • a household appliance in particular a dishwasher, which essentially comprises a spray system and a filter assembly.
  • the filter assembly is arranged in a lower area of the washing container of the dishwasher.
  • the filter assembly is plate-shaped and has a first Filter region arranged in an outer ring of the plate-shaped filter assembly and a second filter region arranged in an inner ring of the plate-shaped filter assembly.
  • the filter unit also has a plate-shaped design and comprises a first and a second filter device.
  • the first filter device has separate segments with a fine-mesh filter membrane.
  • the second filter device on the other hand, consists of a coarse-mesh filter membrane. With these different membranes, different particles can be filtered out of the fluid.
  • a washing machine with a tub in which laundry is washed and a stirring unit is disclosed.
  • a filter container can be inserted into the tub. Fibers that come loose from the laundry are collected in the filter container.
  • the object of the invention is achieved by a household appliance for treating laundry.
  • the household appliance comprises a base and a
  • the household appliance also has a pump unit for pumping around and/or pumping out the fluid present during a cleaning and/or drying process.
  • the pump unit is essentially driven by a drive unit.
  • the household appliance according to the invention also has a control unit for controlling the drive unit and a filter unit for filtering the fluid, wherein the filter unit comprises several filter assemblies.
  • the several filter assemblies are arranged in series and are each fluidically connected to one another via at least one overflow.
  • the overflow prevents the filter unit or filter assemblies from becoming clogged, so that even if one filter assembly becomes clogged, the fluid can be filtered in another filter assembly of the filter unit. This also ensures that the filter unit can be used for longer without having to clean or replace the filter. This also prevents the fluid from escaping uncontrollably from the cleaning and/or drying process if the filter unit becomes clogged.
  • the filter unit has a filter inlet and a filter outlet, wherein the fluid flows into the filter unit through the filter inlet and the fluid flows along a filter path to the filter outlet and flows out of the filter unit through the filter outlet, wherein the fluid flows along the filter path essentially due to gravity.
  • the filter unit in order to be able to arrange the multiple filter assemblies, the filter unit must have a certain height.
  • the filter unit's structure can vary depending on the space available.
  • the filter unit preferably extends from the top of the device almost to the bottom of the device.
  • the multiple filter assemblies each have an upper filter area and a lower filter area, wherein the upper filter area is arranged in the area of the top of the device and the lower filter area is arranged in the area of the bottom of the device. Furthermore, an overflow edge of the overflow is formed in the upper filter area and/or lower filter area.
  • the fluid acts on the filter assembly arranged closest to the filter inlet, wherein the plurality of filter assemblies are arranged such that the fluid flows over at least one overflow edge of an overflow into a nearest filter assembly when the filter assembly acted upon by the fluid is essentially impermeable to flow due to deposits of fluid particles.
  • the filtering process can continue because the fluid can flow over the overflow edge to the nearest filter assembly.
  • the multiple filter assemblies are essentially arc-shaped.
  • the deposits or dirt particles of the fluid can slide into the lower filter area due to gravity while filtration is maintained in the upper filter area.
  • the multiple filter assemblies are arranged in a cascade.
  • the cascade-shaped or stepped arrangement ensures that the fluid flows to another filter assembly due to gravity.
  • a meandering filter path means that the fluid looks for a way to flow through the filter unit. However, this depends on the accumulation of dirt particles.
  • the meandering filter path essentially extends from the filter inlet to the filter outlet.
  • the object is achieved by a method for filtering fluids in a household appliance for treating laundry.
  • the household appliance for treating laundry comprises a base of the appliance and a top of the appliance, the top of the appliance being arranged opposite the base of the appliance.
  • the household appliance for treating laundry also comprises a pump unit for pumping around and/or pumping out the fluid present during a cleaning and/or drying process, and a drive unit for essentially driving the pump unit.
  • the drive unit is controlled by a control unit.
  • the household appliance for treating laundry also has a filter unit for filtering the fluid, the filter unit comprising a plurality of filter assemblies.
  • the plurality of filter assemblies are arranged in series and are fluidically connected to one another via at least one overflow.
  • the fluid is pumped via the pump unit to a filter inlet through which the fluid flows into the filter unit, so that the fluid flows through the filter unit along a filter path due to gravity and acts on at least one of the plurality of filter assemblies, and flows out of the filter unit filtered through a filter outlet, wherein the filter path extends from the filter inlet to the filter outlet.
  • the fluid flows through the filter inlet to a filter assembly arranged closest to the filter inlet and the fluid flows through the filter assembly until the filter assembly becomes essentially impermeable to flow.
  • the fluid flows over an overflow edge of the overflow to a filter assembly closest to the substantially impermeable filter assembly.
  • the filtering process can continue even if one filter assembly or a large number of the filter assemblies of the multiple filter assemblies have become almost impermeable to flow.

  • the filter frame 17 of the filter assembly 13 essentially has an arc-shaped design, so that the Filter membrane 19 is bent and accommodated in the filter frame 17.
  • the curved design of the filter assembly can be banana-shaped.
  • the filter membrane 19 has an upper filter area 21 and a lower filter area 23. Depending on how the filter membrane 19 is made of Fig. 2 is integrated into the filter unit 15, the Fig. 2 Turn over the upper and lower filter areas 21, 23 shown. Ideally, the upper filter area 21 is arranged in the area of the top 12a of the device and the lower filter area 23 in the area of the bottom 12b of the device.
  • the filter membrane 19 can have any membrane pattern.
  • the filter assembly 13 has an overflow edge 25.
  • the overflow edge 25 can be arranged either in the upper filter area 21 or in the lower filter area 23 of the filter frame 17.
  • the overflow edge 25 is arranged on the side of the filter frame 17 that faces the top 12a of the appliance.
  • An overflow 27 is formed in the area of the overflow edge 25.
  • the overflow preferably extends between the overflow edge 25 and the top 12a of the household appliance 1.

  • the filter housing 29 essentially comprises a filter inlet 31 and a filter outlet 33.
  • the filter inlet 31 is preferably formed in the area of the top 12a of the device.
  • the filter outlet 33 is preferably formed in the area of the bottom 12b of the device. This arrangement ensures that fluid 35 can flow from the filter inlet 31 to the filter outlet 33 due to gravity.
  • Arrow A shows the direction of flow of the fluid 35 through the filter inlet 31 into the filter unit 15.
  • Arrow B shows the direction of flow of the fluid 35 through the filter outlet 33 out of the filter unit 15.

  • the filter path 37 can run differently depending on the degree of contamination of the filter unit 15, but always extends from the filter inlet 31 to the filter outlet 33.
  • the filter inlet 31 and the filter outlet 33 are also formed at a different location on the filter unit 15.
  • the filter inlet 31 and the filter outlet 33 can also be formed on a side wall 40 of the household appliance. It only has to be ensured that the fluid 35 can flow in the filter unit 15 due to gravity.
  • the filter unit 15 comprises Fig.3 several filter assemblies 13.
  • the filter assemblies 13 are arranged in series. Furthermore, the several filter assemblies are arranged in a cascade or step-like manner.
  • the filter assemblies 13 are firmly connected to the filter unit 15.
  • the filter assemblies 13 of the filter unit 15 are designed to be removable, for example for cleaning purposes. During operation of the household appliance 1, in particular during cleaning and/or drying processes, it must be ensured that the individual filter assemblies 15 are firmly anchored in the filter unit 15. The fluid 35 acting on the filter assemblies 13 must not cause them to be torn out of their anchorage and thus disrupt a filtering process.
  • the filter assemblies 13 are essentially curved. However, the filter assemblies 13 can also be designed in a slightly bent configuration, as in Fig.3 shown. However, it is also conceivable that the filter assembly can be hook-shaped, banana-shaped or any other shape. In Fig.3 the filter unit 15 has seven filter assemblies 13. However, more or fewer filter assemblies 13 are also conceivable. In order to ensure a long operating time without cleaning the filter unit 15, it is advantageous if the filter unit 15 extends from the top 12a of the device almost to the bottom 12b of the device. Depending on the space available in the household appliance 1, the design of the filter unit 15 can vary and be made larger or smaller.

  • Deposits of fluid particles 39 are in Fig.3 shown by way of example on the first two filter assemblies 13, which are arranged closest to the filter inlet 31.
  • These fluid particles 39 can consist of hair, fibers from clothing or shoes, fats, sand, food scraps, microplastic particles and/or dust or dirt particles.
  • more filter assemblies 13 can be wetted with dirt particles or fluid particles 39.
  • a filtering process of the filter unit 15 is briefly described below.
  • the fluid 35 flows into the filter unit 15 via the filter inlet 31 in the direction of arrow A. After passing through the filter inlet 31, the fluid 35 hits the filter assembly 13 closest to the filter inlet 31 and flows through this first filter assembly 13. Due to the arrangement of the several filter assemblies 13 in Fig.3 , the fluid 35 must pass through all filter assemblies 13 of the filter unit 15, whereby the fluid particles 39 are essentially filtered out by the filter assembly 13 closest to the filter inlet 31. If the filtering process is already advanced, it can be done as in Fig.3 As shown, deposits of fluid particles 39 may already occur.
  • a filter assembly 13 If a filter assembly 13 is wetted with fluid particles 39 to such an extent that the fluid 35 can no longer flow through a filter membrane 19 of a filter assembly 13, the fluid 35 flows over the overflow edge 25 in the direction of arrow C into the filter assembly 13 closest to the filter assembly 13 through which the flow is not intended.
  • a filter assembly 13 does not have to become completely impermeable to flow. Partial impermeability is already sufficient for the fluid 35 to rise within a filter assembly 13 so that the fluid 35 flows to the downstream filter assemblies 13.
  • the fluid 35 flows over the overflow 27 into a downstream filter assembly 13 until a filter assembly 13 is reached in which the fluid 35 can flow through the filter membrane 19. It can happen that the fluid 35 flows along a meandering filter path 37.
  • the meandering filter path 37 means that the fluid 35 in the filter unit 15 seeks a path through the arrangement of the filter assemblies 13, so that it reaches a filter assembly through which the fluid must flow and reaches the filter outlet 33.
