Definitions

  • the present invention relates to a household appliance for treating laundry.
  • Filter units used for filtering fluids are used in household appliances for treating laundry.
  • the household appliance can Carry out cleaning and / or drying processes.
  • the laundry is received in a receptacle of the household appliance.
  • the receiving container is moved during the cleaning and / or drying process with the introduction of mechanics essentially around an axis of rotation.
  • the laundry received in the receptacle is moved and simultaneously mixed with a fluid.
  • the fluid mainly consists of a water-soap mixture, also known as wash liquor, and during the drying process, it mainly consists of steam or process air.
  • the fluids also mix with particles that are released from clothing.
  • the particles can be dust and / or dirt particles, for example.
  • fibers in particular microplastic fibers, which, among other things, contained in fleece garments, from laundry. In this case, the main focus is on the fibers, which are increasingly detached from the laundry during these processes. In order to achieve good cleaning or drying success or to provide environmentally friendly cleaning and / or drying processes, these fibers must be removed from the fluids again.
  • the filtering can take place before a pumping process of the fluid. If the fluid is no longer required for the respective process, the fluid is pumped off and passed into a drain line. In the area of this drain line, the fluid is also passed through a filter insofar as it has not already been filtered before this area.
  • Filter systems in washing machines that are equipped with pumping units are, among other things, from the script US 2013/0312201 A1 known.
  • This document describes a washing machine with a pumping unit, in which the wash liquor is pumped into a pumping unit, also called a recirculation system, by means of a pump unit and is pumped through a filter unit. The filtered fluid is then returned to the washing process directed.
  • the filter unit has a filter and a measuring unit. The measuring unit measures a flow rate or flow rate of the wash liquor and recognizes from the measured values whether the filter is clogged. If this is the case, the washing machine then stops the pumping process. In order to be able to continue the washing process, a new washing solution is added to the washing process.
  • a filter unit in washing machines with pumping systems, in which the filter unit is composed of two filters.
  • the first filter is designed as a wide-mesh filter and the second filter as a narrow-mesh filter.
  • the wash liquor flows through the first filter when the wash liquor is led into a drain line.
  • the wash liquor flows through the second filter when the wash liquor is fed into the pumping system.
  • the object of the invention is achieved by a household appliance for treating laundry, the household appliance being a receptacle for Includes laundry and the receptacle is rotatably received in the household appliance.
  • the household appliance according to the invention comprises a drive unit for driving the receptacle, a control unit for controlling the drive unit, a pump unit for pumping around and / or pumping out the fluid present during a cleaning and / or drying process in such a way that the fluid passes through a filter unit in a filter phase for filtering fibers detachable from the laundry essentially during the cleaning and / or drying process, the control unit being designed such that the receiving container is in a rest position in the filter phase.
  • the cleaning process essentially comprises at least one washing phase, at least one rinsing phase and at least one filter phase, the rinsing phase further comprising at least one spinning sequence and at least one rinsing sequence.
  • the filter phase starts up after a washing and / or rinsing phase, preferably after almost every washing and / or rinsing phase, preferably after every washing and / or rinsing phase.
  • the drying process preferably essentially comprises at least one spin phase and at least one drying phase. It is therefore a further advantage of the embodiment according to the invention that the filter phase after a spinning sequence and / or phase and / or drying phase, preferably after almost every spinning sequence and / or phase and / or drying phase, preferably after each spinning sequence and / or phase and / or drying phase takes place.
  • the filter phase advantageously takes place before a washing and / or rinsing and / or drying phase or in an interruption of the washing and / or rinsing and / or drying phase, preferably in almost every interruption of the washing and / or rinsing and / or Drying phase, preferably in each interruption of the washing and / or rinsing and / or drying phase.
  • the fibers removed from the laundry in the last phase can be removed from the cleaning and / or drying process , whereby the fibers do not get back into the following phases of the cleaning and / or drying process.
  • the interruptions can be used for filter phases so that there is no extension of the cleaning and / or drying process.
  • the rest position of the receptacle is controlled in such a way that the receptacle takes place along a predetermined braking curve in accordance with a predefinable reduction in speed.
  • This control gently brakes the receptacle. This in turn benefits the laundry to be treated, since less frictional forces occur between the receptacle and the laundry and thus fewer fibers are released from the laundry.
  • Another aspect of the invention is that the fluid present in the cleaning and / or drying process flows after passing through the filter unit into a drain line and / or into a recirculation line for returning the fluid to the cleaning and / or drying process.
  • the filtered, environmentally friendly fluid which is almost free of microfibers, can thus be fed directly into the drain line and / or pumped into the recirculation line in order to be used in the further or new cleaning and / or drying process.
  • a storage element is preferably arranged after the filter unit.
  • the storage element serves to store the filtered fluid, regardless of the further use.
  • the storage element is advantageously designed to store the fluid present in the cleaning and / or drying process after flowing through the filter unit and to guide the fluid via the pump unit to the drain line and / or the recirculation line.
  • the fluid can be collected in the storage element. It can then be pumped into either the drain line or the recirculation line. If the fluid is to be pumped into the drain line, one pumping operation is sufficient with which the fluid collected in the storage element is to be separated. If the fluid is intended for recirculation, the filtered fluid can be kept there until a further phase of the cleaning and / or drying process starts or a new cleaning and / or drying process is initiated. Furthermore, it can be checked whether the stored fluid is sufficient for a further washing and / or drying process or whether new fluid has to be added to the filtered fluid, so that sufficient fluid for a further phase of the cleaning and / or drying process or a new cleaning - And / or drying process is present.
  • the object is achieved by a method for filtering fibers of laundry which are produced in a household appliance for treating laundry.
  • the household appliance comprises a receptacle for laundry, the receptacle being rotatably mounted in the household appliance, a drive unit for driving the receptacle, a control unit for actuating the drive unit, a pump unit for pumping around and / or pumping out the fluid present during the cleaning and / or drying process in this way that the fluid through a filter unit for filtering fibers detaching themselves substantially during the cleaning and / or drying process, the control unit being designed such that the receiving container is stopped in the filter phase for filtering the fluid.
  • the stopping of the receptacle is advantageously controlled in such a way that the receptacle is braked along a predetermined braking curve in accordance with a predeterminable reduction in speed.
  • the filter phase is preferably carried out after one of the phases carried out in the cleaning and / or drying process, the cleaning process essentially comprising a washing process which essentially comprises at least one wetting phase, at least one washing phase, at least one rinsing phase, at least one filter phase and at least one spinning phase , wherein the spinning phase comprises at least one spinning sequence and a rinsing sequence, and wherein the drying process essentially comprises at least one spinning phase and at least one drying phase.
  • the filter phase is advantageously carried out before one of the phases carried out in the cleaning and / or drying process.
  • immediate filtering Before one of the phases of the cleaning and / or drying process it is ensured that in a subsequent phase of the cleaning and / or drying process few or almost no fibers are introduced.
  • the filter phase is carried out while the cleaning and / or drying process is interrupted.
  • this interruption can be used for a filter phase, so that at least one additional filter phase, which would prolong the cleaning and / or drying process, can be omitted and thus shortening or not extending the process.

  • a recirculation unit 10, 35 requires less fluid for a cleaning or drying process, since the already existing fluid, that is to say the fluid already in the cleaning or drying process, is filtered and then pumped back into the cleaning or drying process becomes. With a washing machine A, this means less water and / or detergent consumption. With a dryer B, for example, less warm or hot process air has to be generated, which saves energy costs.
  • the cleaning process for a washing machine A is started, water and a mixture of water and detergent flows into the container and wets the laundry there. With pumping systems, the laundry can be wetted several times. It is also conceivable that a filter phase already takes place after several wetting phases. The washing phase is coupled after the wetting phase. The receptacle 11 rotates so that the laundry is circulated repeatedly. In addition to the dust and dirt particles, this process also removes fibers from the laundry.
  • a filter phase can advantageously be carried out after a washing phase, after almost every washing phase or after each washing phase, in order to remove the fibers from the cleaning process.

  • the receptacle 11 Before the filter phase takes place, the receptacle 11 must be stopped so that it is in a rest position, ie the receptacle 11 no longer moves. Now it is the case that the receptacle 11 moves in the upstream phase, here the washing phase. Abrupt braking, as in a comparative blender that essentially moves into two positions "on” or “off”, should be avoided, since this will detach further fibers from the laundry, as already described in detail above. It is therefore advantageous if the receptacle 11 is braked along a predetermined braking curve according to a predeterminable reduction in speed. The slower the braking, the less fibers are released from the laundry.
  • the moist laundry is circulated in the receptacle 31 and subjected to warm air, process air.

There, the mixture of moist air and fibers is filtered and can either be used further in the same way as the cleaning process described above or can be pumped into the drain line 44. For further use it is necessary that the moisture is extracted from the air or the air is dried.
  • a filter phase advantageously takes place after one of the above-mentioned phases of the cleaning or drying process. However, it is also conceivable that the filter phase takes place after almost every phase or after every phase of the cleaning or drying process.

  • a filter phase can preferably be carried out almost before or before each phase of the cleaning or drying process.
