Definitions

  • the present invention relates to a household appliance for treating laundry.
  • Filter units are used in household appliances for treating laundry to filter fluids.
  • the household appliance can carry out cleaning and/or drying processes, among other things.
  • the laundry is held in a container in the household appliance.
  • the container is essentially moved around a rotation axis using mechanical means.
  • the laundry held in the container is moved and simultaneously mixed with a fluid.
  • the fluid consists mainly of a water-soap mixture, also known as washing liquor, and during the drying process, it consists mainly of steam or process air.
  • the fluids also mix with particles that are released from the clothing.
  • the particles can be dust and/or dirt particles, for example.
  • filtering can take place before the fluid is pumped over. If the fluid is no longer needed for the respective process, the fluid is pumped out and fed into a drain line. In the area of this drain line, the fluid is also passed through a filter, provided it has not already been filtered before this area.
  • Filter systems in washing machines equipped with pumping units are known from the document US 2013/0312201 A1
  • This document describes a washing machine with a pumping unit, in which the washing liquid is pumped by means of a pumping unit into a pumping unit, also known as a recirculation system, and through a filter unit. The filtered fluid is then fed back into the washing process.
  • the filter unit also has a filter and a measuring unit. The measuring unit measures a flow rate or flow rate of the washing solution and uses the measured values to determine 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 for washing machines with pumping systems, in which the filter unit is made up of two filters.
  • the first filter is designed as a wide-mesh filter and the second filter as a narrow-mesh filter.
  • the washing solution flows through the first filter when the washing solution is led into a drain line.
  • the washing solution flows through the second filter when the washing solution is led into the pumping system.
  • a washing machine which includes a collection tank for water.
  • the object of the invention is achieved by a household appliance for treating laundry, wherein the household appliance comprises a receiving container for laundry and the receiving container is rotatably accommodated in the household appliance.
  • the household appliance according to the invention comprises a drive unit for driving the receiving container, 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 in a filtering phase the fluid can be guided through a filter unit for filtering fibers that essentially come off the laundry during the cleaning and/or drying process, wherein the control unit is designed in such a way that the receiving container is in a rest position in the filtering phase, wherein the rest position of the receiving container is controlled in such a way that the receiving container follows a predetermined braking curve according to a predeterminable reduction in speed, whereby a gentle braking of the receiving container can be achieved, which in turn benefits the laundry to be treated.
  • the cleaning process essentially comprises at least one washing phase, at least one rinsing phase and at least one filtering phase, wherein the rinsing phase further comprises at least one spin sequence and at least one rinsing sequence. Therefore, it is a further advantage of the embodiment according to the invention that the filtering phase starts after a washing and/or rinsing phase, preferably after almost every washing and/or rinsing phase, preferably after every washing and/or rinsing phase.
  • new fibers are released from the laundry and are then passed on to the cleaning and/or drying process.
  • the newly released fibers can be removed from the cleaning and/or drying process.
  • the drying process essentially comprises at least one spinning phase and at least one drying phase. Therefore, a further advantage of the embodiment according to the invention is that the filtering phase takes place 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 every spinning sequence and/or phase and/or drying phase.
  • fibers Due to the high speeds that occur during spin sequences and/or phases and/or the air circulation during drying phases, additional or new fibers are increasingly released from the laundry and enter the cleaning and/or drying process. These fibers can be removed from the cleaning and/or drying process by filtering after one of the above-mentioned phases.
  • the filtering phase 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 every interruption of the washing and/or rinsing and/or drying phase.
  • the fibres released from the laundry in the last phase can be removed from the cleaning and/or drying process, so that the fibres do not get back into the following phases of the cleaning and/or drying process. Furthermore, the interruptions can be used for filtering phases so that the cleaning and/or drying process is not extended.
  • a further 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 to be used in the subsequent or new cleaning and/or drying process.
  • a storage element is arranged after the filter unit.
  • the storage element serves to store the filtered fluid, regardless of its further intended use.
  • the storage element is designed to store the fluid present during the cleaning and/or drying process after it has flowed 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 either into the drain line or into the recirculation line. If the fluid is to be pumped into the drain line, a pumping process is sufficient to remove the fluid collected in the storage element. If the fluid is intended for recirculation, the filtered fluid can be stored there until another 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 another washing and/or drying process or whether new fluid must be mixed with the filtered fluid so that there is sufficient fluid for another phase of the cleaning and/or drying process or a new cleaning and/or drying process.
  • the object is achieved by a method for filtering fibers from laundry that accrue in a household appliance for treating laundry.
  • the household appliance comprises a receiving container for laundry, wherein the receiving container is rotatably mounted in the household appliance, a drive unit for driving the receiving container, a control unit for controlling the drive unit, a pump unit for pumping around and/or pumping out the fluid present during the cleaning and/or drying process in such a way that the fluid is passed through a filter unit for filtering fibers that essentially detach from the laundry during the cleaning and/or drying process, wherein the control unit is designed in such a way that the receiving container is stopped in the filtering phase for filtering the fluid, wherein the stopping of the receiving container is controlled in such a way that braking of the receiving container is slowed down along a predetermined braking curve in accordance with a predeterminable reduction in speed, whereby a gentle braking of the receiving container is achieved, which in turn benefits the laundry to be treated.
  • the filtering phase is carried out after one of the phases carried out in the cleaning and/or drying process, wherein the cleaning process essentially comprises a washing process which essentially comprises at least one wetting phase, at least one washing phase, at least one rinsing phase, at least one filtering phase and at least one spinning phase, wherein the spinning phase comprises at least one spinning sequence and one rinsing sequence, and wherein the drying process essentially comprises at least one spinning phase and at least one drying phase.
  • the cleaning process essentially comprises a washing process which essentially comprises at least one wetting phase, at least one washing phase, at least one rinsing phase, at least one filtering phase and at least one spinning phase
  • the spinning phase comprises at least one spinning sequence and one rinsing sequence
  • the drying process essentially comprises at least one spinning phase and at least one drying phase.
  • the filtering phase is carried out before one of the phases carried out in the cleaning and/or drying process.
  • filtering immediately before one of the phases of the cleaning and/or drying process it is ensured that few or almost no fibres are introduced in a subsequent phase of the cleaning and/or drying process.
  • the filtering phase is carried out during an interruption of the cleaning and/or drying process.
  • this interruption can be used for a filtering phase, so that at least one additional filtering phase, which would prolong the cleaning and/or drying process, can be omitted and the process is thus shortened or not extended.
  • FIG. 1 and 2 A schematic front view of a household appliance 1 is shown, in which Fig. 1 a washing machine A and Fig. 2 a dryer B is shown.
  • FIG. 1 is a schematic front view of a household appliance 1 for treating laundry, in particular a washing machine A.
  • the household appliance 1 has a washing machine front wall 2.
  • a washing machine front wall 2 On the washing machine front wall 2 there is arranged, among other things, a movable dispenser tray 3 into which a washing care substance, such as detergent, can be filled, and a washing machine display unit 4 with which, among other things, a washing program can be set.
  • a pivoting washing machine door 5 is arranged on the washing machine front wall 2 of the household appliance 1.
  • FIG. 2 is a schematic front view of a household appliance 1 for treating laundry, in particular a dryer.
  • the household appliance 1 in Fig. 2 has a dryer front wall 6.
  • a heat exchanger tray 7, also referred to as a condensate tray, and a dryer display unit 8 are arranged.
  • a pivotable dryer door 9 is arranged on the dryer front wall 6 of the household appliance 1.
  • a washer-dryer is also included under a household appliance 1 for laundry care, but a more detailed explanation is omitted below.
  • the fluid that flows, streams or is used in the household appliance 1 can be, among other things, water, washing solution or fabric softener in washing machines A.
  • the fluid In dryers, the fluid is usually air or process air.
  • FIG. 3 is a schematic view of a household appliance for treating laundry using a circulation principle. This is a schematic interior view of a washing machine.
  • the laundry care device 1 comprises a recirculation unit 10, a receiving container 11 for receiving laundry, also referred to as a washing drum, and a lye container 12 for receiving washing lye.
  • the receiving container 11 is rotatably received in the lye container 12.
  • the lye container 12 also has a feed opening 13 and a discharge opening 14 with a discharge line 14a.
  • the recirculation unit 10 comprises a recirculation line 15 which fluidically connects the feed opening 13 with the discharge line 14a and thus with the discharge opening 14.
  • the recirculation unit 10 also comprises a pump unit 16 connected to the recirculation line 15.
  • the pump unit 16 is designed to pump or recirculate washing liquor through the discharge opening 13 from the suds container 12 into the recirculation line 15 of the recirculation unit 10 and to pump the washing liquor from the recirculation line 15 through the feed opening 13 into the suds container 12 again.
  • the pump unit 16 essentially has a pump drive 17a and at least one pump 17b.
  • the pump drive 17a essentially drives the at least one pump 17b.
  • the washing care appliance 1 also comprises a rinsing device 18 which is connected to the suds container 12 by a rinsing line 19 in order to introduce fresh water into the suds container 12, among other things.
  • the household appliance 1 further comprises a drive unit 20 for driving the receiving container 11 and a control unit 21 for controlling the drive unit 20.
  • the control unit 21 is connected to the drive unit 20 via a drive control line 22 and to the pump unit 16 via a control connection 23.
  • the household appliance 1 also has a drain line 25 which directs the washing solution to a drain (not shown) if it can no longer be used or is no longer required.
  • the drain line 25 is also fluidically connected to the discharge opening 14.
  • a filter unit 27 is arranged in the area of the discharge line 14a, which filters the washing liquor that flows or is pumped out of the discharge opening 14.
  • the filter unit 27 can be arranged before or after the pump unit 16.
  • the composition of the filter unit 27 can be chosen as desired, so that an optimal composition can be achieved for the intended use. However, the filter unit 27 should definitely be selected so that the dust and dirt particles mentioned above as well as the fibers can be filtered out of the washing liquor.
  • the recirculation line 15 and the drain line 25 are connected downstream of the filter unit 27 in terms of fluid technology, so that the fibers cannot get into one of these lines 15, 25.
  • the control unit 21 determines which of the two lines 15, 25, recirculation line 15 or drain line 25, the washing liquor is ultimately pumped into. This can depend on the degree of soiling of the washing solution or on a cleaning process.
  • a cleaning process can comprise several phases, which are discussed in more detail below.
  • a storage element 29 can be connected downstream of the filter unit 27.
  • the storage element 29 can preferably be arranged in the recirculation unit 10.
  • the recirculation line 15 can be designed in one piece or in multiple pieces, depending on where the storage element 29 is arranged.
  • the storage element 29 serves to store water and/or washing solution that is not required for the current cleaning process or one of the phases of the cleaning process, or is collected there to be used for a further cleaning process.
  • the storage element 29 can also be arranged in the area of the drain line 25 in order to collect the drain water there. This can reduce the number of pumping processes, since, for example, pumping only has to take place once in a cleaning process. This would help to reduce the time required for the cleaning process.
  • the storage element 29 is arranged in front of the filter unit 27 and stores the water or the washing solution, which passes from the suds container 12 via the discharge opening 14 into the discharge line 14a, in front of the filter unit 27.
  • a cleaning process essentially comprises at least one wetting phase, at least one washing phase, at least one rinsing phase and at least one filtering phase.
  • the rinsing phase is in turn divided into at least one spinning sequence and at least one rinsing sequence. How often one of the above-mentioned phases is carried out depends, among other things, on the amount of laundry to be cleaned and the degree of soiling of the laundry as well as on the selection of the cleaning program.
  • the laundry is wetted with water or washing solution. This can be done via injection nozzles (not shown) and/or via the rinsing line 19. The wetting phases can be repeated as often as required.
  • the washing phase the laundry is circulated and washed while the receiving container 11 rotates. The laundry soaked with washing solution is rinsed in the rinsing phase so that the washing solution is rinsed out of the laundry. This is usually done by means of several spinning and rinsing sequences.
  • the laundry is moved back and forth in the receiving container 11 and thereby experiences friction, which is caused by the rotation of the receiving container 11 or the washing solution or water is created.
  • the dust and dirt particles are released from the laundry, but fibers, in particular microplastic fibers, are also released from the laundry. These fibers are harmful to the environment and contaminate the cleaning process.
  • the dust and dirt particles as well as the fibers are filtered out of the washing solution or the water discharged through the discharge opening 14 by the filter unit 27.
  • the above-mentioned filter phases are intended for this purpose.
  • the water and/or the washing solution in the tub 12 is pumped by the pump unit 16 through the filter unit 27.
  • the receiving container 11 is in a rest position during the filter phase, i.e. no mechanics or other kinetic energy acts on the receiving container 11.
  • no new washing solution or water is introduced into the tub 12 via the induction line 19.
  • the receiving container 11 is controlled via the control unit 21.
  • the receiving container 11 is preferably braked to the rest position along a predetermined braking curve in accordance with a predeterminable reduction in speed. It is advantageous that the braking does not take place abruptly, so that very high frictional forces can act on the laundry. Braking is preferably carried out as slowly as possible, since this creates the least amount of friction between the laundry and the receiving container 11. However, an unnecessary extension of the cleaning process should be avoided.
  • a filter phase is advantageously carried out after a washing and/or rinsing phase. This means that fibres that have come loose from the laundry in the preceding washing and/or rinsing phase can be removed immediately from the cleaning process, so that, for example, a better cleaning result can be achieved. The more often a filter phase is carried out, the fewer fibres the washing solution or water contains.
  • a filter phase is preferably carried out after almost every washing and/or rinsing phase or even after every washing and/or rinsing phase. It is important that a reasonable number of filter phases are selected so that the cleaning result is optimal, but the duration of the cleaning process does not increase indefinitely.
  • the filter phase takes place before the washing and/or rinsing phase or during an interruption in the washing and/or rinsing phase.
  • This has the advantage that the cleaning process does not have to be interrupted for a long time in order to implement at least one filter phase in the cleaning process.
  • Carrying out the filter phase before a washing and/or rinsing phase has the advantage that the washing solution or the water required for the subsequent phase is filtered immediately before reuse or further use and is therefore introduced into the subsequent phase in a particularly freshly prepared state.
  • the filter phase can preferably be carried out at almost any time, preferably at any interruption in the washing and/or rinsing phase.
  • FIG. 4 is a schematic view of a household appliance 1 for treating laundry using a circulation principle.
  • This is a schematic interior view of a dryer B, with individual components of the dryer only being shown in a highly simplified manner.
  • the household appliance 1 in Fig. 4 also comprises a receiving container 31 for laundry.
  • the dryer B also comprises a filter unit 33 which is arranged in a recirculation circuit of a recirculation unit 35.
  • the fluid that predominantly flows during the drying process is air. This can contain, among other things, moisture particles or be in vapor form.
  • the fluid is led from the receiving container 31 through a discharge opening 36 into a discharge line 36a and pumped through the filter unit 33 by means of a pump unit 37.
  • the filter unit 33 dust particles and/or fibers that come loose from the laundry during the drying process are removed from the fluid.
  • the fluid is pumped back into the receiving container 31 via a feed opening 40 via at least one recirculation line 39.
  • the discharge opening 36 is thus fluidically connected to the feed opening 40. Furthermore, a storage element 45 can be connected downstream of the filter unit 33. Analogous to the storage element 29, the filtered fluid is also stored in the storage element 45 for a new or further drying process. If it is no longer required, the fluid can be removed from the drying process via a drain line 44.
  • the pump unit 37 is controlled by a control unit 41.
  • the control unit 41 controls also a drive unit 43, wherein the drive unit 43 drives the receiving container 31.
  • the pump unit 37 comprises at least one pump 38a and a pump drive 38b.
  • a drying process essentially comprises at least one spin phase and at least one drying phase.
  • the spin phase the laundry contained in the receiving container 31 gives off moisture. This moisture is pumped out of the receiving container 31 of the dryer B via a discharge opening 36.
  • warm air usually enters the receiving container 31 to dry the damp laundry.
  • fibers come loose from the laundry. Analogous to the washing process, these fibers must be removed from the drying process. The fibers and the air that is contaminated with moisture particles are pumped through the filter unit 33.
  • the receiving container 31 is in a rest position during a filter phase in the drying process.
  • a filter phase can preferably take place after a spinning and/or drying phase, preferably after almost every, preferably after every spinning and/or drying phase. It is also conceivable here for the filter phase to take place before the spinning and/or drying phase, preferably before almost every, preferably before every spinning and/or drying phase.
  • the filter phase can also take place during an interruption in the drying process, preferably in almost every interruption, preferably in every interruption.
  • the fluid After flowing through the filter unit 27, 33, it is conceivable during both the cleaning process and the drying process that the fluid is pumped either into the drain line 25, 44, if one is present, or into a recirculation line 15, 43, which is arranged in the recirculation unit 10, 35.
  • the recirculation line 15, 43 guides the fluid back into the receiving container 31 and is used there to continue the cleaning or drying process. If the fluid is no longer required for the current cleaning or drying process or if the cleaning or drying process has already ended, the fluid can be stored or temporarily stored in a storage element 29, 45 for a new drying process.
  • a recirculation unit 10, 35 means that less fluid is required for a cleaning or drying process, since the fluid already present, i.e. the fluid already in the cleaning or drying process, is filtered and then pumped back into the cleaning or drying process. In a washing machine A, this means less water and/or detergent consumption. In a dryer B, for example, less warm or hot process air needs to be generated, which saves energy costs.
  • the cleaning process in a washing machine A is started, water and a mixture of water and detergent flows into the container and wets the laundry there.
  • the laundry can be wetted several times with pumping systems.
  • a filter phase takes place after several wetting phases.
  • the washing phase follows the wetting phase.
  • the receiving container 11 rotates so that the laundry is repeatedly circulated. During this process, not only the dust and dirt particles but also fibers are released from the laundry.
  • a filter phase can take place after a washing phase, after almost every washing phase or after every washing phase in order to remove the fibers from the cleaning process.
  • the washing liquor flows through the discharge opening 14 from the lye container 12 into the discharge line 14a.
  • the pump unit 16 pumps the washing liquor to or through the filter unit 27, in which, among other things, the fibers are filtered out of the washing liquor.
  • the washing liquor is then pumped into the storage element 29 and stored there until it is needed for the current or a subsequent cleaning process.
  • the washing liquor returns to the receiving container 11 or the lye container 12 via the recirculation unit 10. If the washing liquor is no longer suitable for further use for various reasons, it can also be pumped into the drain line 25 after passing through the filter unit 27. However, before the filtering phase takes place, the receiving container 11 must be stopped so that it is in a rest position, i.e. the receiving container 11 no longer moves.
  • the receiving container 11 moves in the upstream phase, in this case the washing phase.
  • Abrupt braking as with a mixer, which essentially has two positions “on” or “off”, should be avoided, as this causes further fibers to detach from the laundry, as already described in detail above. It is therefore advantageous if the receiving container 11 is braked along a predetermined braking curve according to a predeterminable reduction in speed. The slower the braking, the fewer fibers will detach from the laundry.
  • the damp laundry is circulated in the receiving container 31 and exposed to warm air, process air. This causes fibers, among other things, to come loose from the laundry.
  • the mixture of damp air and fibers is pumped out of the receiving container 31 and to the filter unit 33. There, the mixture of damp air and fibers is filtered and can either be reused in the same way as the cleaning process described above or pumped into the drain line 44. For further use, it is necessary that the moisture is removed from the air or that the air is dried.
  • a filtering phase takes place after one of the above-mentioned phases of the cleaning or drying process.
  • the filtering phase takes place after almost every phase or after every phase of the cleaning or drying process.
  • Interruptions can occur during a cleaning or drying process. It is therefore also conceivable to use these interruptions for a filtering phase in order not to prolong the cleaning or drying process. Preferably, almost any and/or every interruption can be used for a filtering phase.
  • a filtering phase takes place before a phase of the cleaning or drying process.
  • a filtering phase can take place almost before any or all phases of the cleaning or drying process.
