Description

The present invention relates to a household appliance for the treatment of laundry according to the preamble of claim 1 and to a method for filtering fibers of laundry.

Household laundry appliances use filter units that filter fluids. The household appliance can u.a. Perform cleaning and / or drying operations. In these operations, the laundry is accommodated in a receptacle of the household appliance. The receptacle is moved during the cleaning and / or drying process with the introduction of mechanics substantially about an axis of rotation. The laundry received in the receptacle is moved and simultaneously mixed with a fluid. The fluid consists during the cleaning process mainly from a water-soap mixture, also referred to as wash liquor, and during the drying process mainly from steam or process air.

During cleaning and / or drying operations, the fluids also mix with particles that are released from the clothing. The particles may be, for example, dust and / or dirt particles. Furthermore, fibers, in particular microplastic fibers, which i.a. included in fleece garments, from the laundry. In this case, the main focus is on the fibers, which increasingly dissolve out of the laundry in these processes. In order to achieve a good cleaning or drying success or to provide environmentally friendly cleaning and / or drying operations, these fluids must be removed from the fluids again. In pumping systems, filtering may take place before pumping the fluid. If the fluid is no longer needed for the respective process, the fluid is pumped out and directed into a drain line. In the area of this drain line, the fluid is also passed through a filter, unless it has already been filtered before this area.

Filter systems in washing machines that are equipped with Umpumpeinheiten, u.a. known from the document US 2013/0 312 201 A1. In this document, a washing machine with a transfer unit is described in which the wash liquor is pumped by means of a pump unit into a transfer unit, also called recirculation system, and through a filter unit. Subsequently, the filtered fluid is returned to the washing process. Furthermore, the filter unit has a filter and a measuring unit. The measuring unit measures a flow rate or flow rate of the washing liquor and recognizes from the measured values whether there is a blockage of the filter. If this is the case, then the washing machine stops the pumping process. In order to continue the washing process, a new wash is added to the washing process.

In another document, the US Pat. No. 4,833,900 , a filter unit is described in washing machines with pumping systems, in which the filter unit consists of two filters. The first filter is designed as a wide-meshed filter and the second filter as a close-meshed filter. The first filter is flowed through by the wash liquor when the wash liquor is fed into a drain line. The second filter is flowed through by the wash liquor when the wash is passed into the pumping system.

The DE 10 2011 086 137 A1 describes a waxing machine that essentially comprises a plurality of filtration devices and a storage container. Furthermore, the washing machine from the DE 10 2011 086 137 A1 Turbidity sensors for detecting a content of the water to impurities and / or salts of the water passed through the filtration devices.

As can be seen from the two publications cited above, various filter systems for pumping systems of the prior art are known which filter fibers from the pumping system or recirculation system. During the filtering operations, the cleaning or drying process is usually continued, i. the receptacle continues to rotate. As a result, fibers are released from the laundry almost incessantly.

It is therefore the object of the invention to design a household appliance with a cleaning or drying process, in which during the filtering process, the release of fibers from the laundry is prevented or reduced, so that during a cleaning or drying process, a low-fiber fluid prevails in the receptacle.

This object is solved by the features of patent claim 1. Advantageous embodiments are subject of the dependent claims, the description and the drawings.

According to one aspect, the object of the invention is achieved by a household appliance for the treatment of laundry, wherein the household appliance comprises a receptacle for laundry and the receptacle is rotatably received in the household appliance. Furthermore, 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 and / or pumping the fluid present in a cleaning and / or drying operation such that in a filter phase the fluid can be guided through a filter unit for filtering fibers which essentially dissolve away from the laundry during the cleaning and / or drying process, the control unit being designed in such a way that that the receptacle is in a rest position in the filtering phase.

By stopping the receptacle no further fibers are released from the laundry during the filter phase and the recycled fluid is thus almost fiber-free pumped back into the cleaning and / or drying process and can apply the laundry almost fiber-free repeated or wet.

Advantageously, the cleaning process essentially comprises at least one washing phase, at least one rinsing phase and at least one filtering phase, the rinsing phase furthermore comprising at least one spin-drying sequence and at least one rinsing sequence. Therefore, it is a further advantage of the embodiment according to the invention that the control unit controls the cleaning process in such a way that the filter phase starts after a washing and / or rinsing phase, preferably after almost every washing and / or rinsing phase, preferably after each washing and / or rinsing phase ,

In each washing and / or rinsing phase, new, new fibers are released from the laundry, which enter the cleaning and / or drying process. By filtering the fluid after one of these operations, the newly dissolved fibers can be removed from the cleaning and / or drying process again.

Preferably, the drying process essentially comprises at least one spin phase and at least one drying phase. Therefore, a further advantage of the embodiment according to the invention is that the control unit controls the drying process in such a way that the filter phase after a spin sequence and / or phase and / or drying phase, preferably after almost every spin sequence and / or phase and / or drying phase, preferably after each spin sequence and / or phase and / or drying phase takes place.

Due to the high speeds that occur in spin sequences and / or phases, and / or by the air circulation during drying phases more or new fibers are increasingly released from the laundry, which get into 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.

Advantageously, the control unit controls the cleaning and / or drying process such that the filter phase 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 any interruption of the washing and / or rinsing and / or drying phase, preferably in any interruption of the washing and / or rinsing and / or drying phase.

Before the washing and / or rinsing and / or drying phases or in the interruptions of the washing and / or rinsing and / or drying phases, the cleaning and / or drying process can be removed from the fibers dissolved in the last phase of the laundry , whereby the fibers do not get back into the following phases of the cleaning and / or drying process. Furthermore, the interruptions can be used for filter phases, so that no extension of the cleaning and / or drying process arises.

It is particularly advantageous that the control unit controls the rest position of the receptacle such that the receptacle along a predetermined braking curve according to a predeterminable reduction in speed takes place.

By this control, a gentle braking of the receptacle is accomplished. This, in turn, benefits the laundry to be treated, as this results in less frictional forces occurring between the receptacle and the laundry and thus less fibers are released from the laundry.

A further aspect of the invention is that the control unit activates the cleaning and / or drying process in such a way that the fluid present in the cleaning and / or drying process after passing through the filter unit into a drain line and / or into a recirculation line for returning the fluid into the Cleaning and / or drying process flows.

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 further or new cleaning and / or drying process.

Preferably, a storage element is arranged after the filter unit.
The storage element is used for storing the filtered fluid, regardless of the further intended use.

Advantageously, the storage element is 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 outflow line and / or the recirculation line.

The fluid can be collected in the storage element. Then it can either be pumped into the drain line or into the recirculation line. If the fluid is to be pumped into the drain line, an exhaust pumping process with which the fluid collected in the storage element is to be eliminated is sufficient. If the fluid is provided 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 a further washing and / or drying process or whether new fluid must 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.

According to a second aspect of the invention, the object is achieved by a method for filtering fibers of laundry obtained in a domestic appliance for the treatment of laundry. The household appliance comprises a receptacle for laundry, wherein the receptacle is rotatably mounted in the household appliance, a drive unit for driving the receptacle, a control unit for driving the drive unit, a pump unit for pumping and / or pumping out of the existing during cleaning and / or drying fluid such in that the fluid is passed through a filter unit for filtering fibers which are released from the laundry substantially during the cleaning and / or drying process, the control unit being designed such that the receptacle is stopped in the filter phase for filtering the fluid.

Thereby, the technical advantage is achieved by stopping the receptacle to prevent the receptacle continues to move during the filtering phase, to prevent the detachment of fibers from the laundry during the filtering phase.

Advantageously, the stopping of the receiving container is controlled in such a way that the receiving container is braked along a predetermined braking curve according to a predefinable reduction in the speed.

An abrupt deceleration of the receptacle is thereby avoided, so that little to almost no friction between the laundry and the receptacle is formed, whereby fibers are released from the laundry. Thus, the slow or deceleration along a predetermined braking curve according to a predeterminable reduction in speed on the one hand gentle for the laundry and the other environmentally friendly, since less microplastic fibers dissolve from the laundry.

The filter phase is preferably carried out according to 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 spin phase wherein the spin phase comprises at least one spin sequence and one purge sequence, and wherein the drying process substantially comprises at least one spin phase and at least one drying phase.

This has the advantage that the fibers produced in one of the phases of a cleaning and / or drying process are removed immediately after the end of this phase from the cleaning and / or drying process.

Advantageously, the filter phase is carried out before one of the phases carried out in the cleaning and / or drying process. The immediate filtering before one of the phases of the cleaning and / or drying process ensures that in a subsequent phase of the cleaning and / or drying process few or almost no fibers are introduced.

It is particularly advantageous if the filter phase is carried out in an interruption of the cleaning and / or drying process.

Since the interruption of the cleaning and / or drying process, the process is already delayed, this interruption can be used for a filter phase, so that at least one additional filter phase, which would drag the cleaning and / or drying process in the length, can be omitted, and thus shortened or not extended the process.

In the 1 and 2 is a schematic front view of a household appliance 1 shown, in 1 a washing machine A and 2 a dryer B is shown.

In 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 on. At the washing machine front wall 2 is, inter alia, a movable Einspülschale 3 into which a washing care substance, such as detergent, can be filled, and a washing machine display unit 4 with which, inter alia, a washing program can be adjusted arranged. Furthermore, there is a swiveling washing machine door 5 on the washing machine front wall 2 of the household appliance 1 arranged.

Furthermore, a hinged dryer door 9 on the dryer front wall 6 of the household appliance 1 arranged.

Also is under a household appliance 1 to read a washer-dryer for laundry care, but will be omitted in the following on a more detailed explanation.

The fluid that is in the household appliance 1 flows, flows or is used in washing machines A including water, washing liquor or softener. For dryers, the fluid is mostly air or process air.

In 3 is a schematic view of a household appliance for treating laundry with a circulation principle shown. This is a schematic inside view of a washing machine.

The following is the washing care device 1 using a washing machine A described in more detail. The washing care device 1 includes a recirculation unit 10 , a receptacle 11 for holding laundry, also referred to as a washing drum, and a tub 12 for the absorption of washing liquor. The receptacle 11 is rotatable in the tub 12 added. The tub 12 also has a feed opening 13 and a discharge opening 14 with a discharge line 14a on. The recirculation unit 10 includes a recirculation line 15 that the feed opening 13 Fluidtechnisch with the discharge line 14a and thus with the discharge opening 14 combines. Furthermore, the recirculation unit comprises 10 one with the recirculation line 15 connected pump unit 16 , The pump unit 16 is designed such that wash liquor through the discharge opening 13 from the tub 12 in the recirculation line 15 the recirculation unit 10 pump or pump and the wash liquor from the recirculation line 15 through the feed opening 13 again in the tub 12 to pump. The pump unit 16 essentially has a pump drive 17a and at least one pump 17b on. The pump drive 17a essentially drives the at least one pump 17b at. Furthermore, the laundry care appliance includes 1 a dispenser 18 that with the tub 12 through a flushing line 19 connected to, among other things, fresh water in the tub 12 introduce.

The household appliance 1 further comprises a drive unit 20 for driving the receptacle 11 and a control unit 21 for driving the drive unit 20 , The control unit 21 is via a drive control line 22 with the drive unit 20 and via a control connection 23 with the pump unit 16 connected. Furthermore, the household appliance 1 a drainage line 25 on, the wash liquor, if it can no longer be used or is needed, to a drain (not shown) passes. The drainage line 25 is also fluidtechnisch with the discharge opening 14 connected.

In the area of the discharge line 14a is a filter unit 27 arranged the suds flowing out of the discharge opening 14 flows or is pumped, filters. The filter unit 27 can be before or after the pumping unit 16 be arranged. The composition of the filter unit 27 can be chosen arbitrarily, so that an optimal composition for the application can be made. The filter unit 27 In any case, it should be chosen so that the dust and dirt particles mentioned at the beginning as well as the fibers are filtered out of the wash liquor can. Fluidtechnisch the filter unit 27 downstream is the recirculation line 15 and the drainage line 25 so that the fibers do not get into one of these wires 15 . 25 can reach. In which of the two lines 15 . 25 , Recirculation line 15 or drain line 25 , the wash liquor is ultimately pumped by the control unit 21 certainly. This can be dependent on the degree of soiling of the wash liquor or on a cleaning process. A cleaning process may include several phases, which will be discussed in more detail below.

Furthermore, the filter unit 27 a memory element 29 be downstream.
The storage element 29 may preferably be in the recirculation unit 10 be arranged. The recirculation line 15 can be formed in one piece or several pieces, depending on where the storage element 29 is arranged. The storage element 29 serves to store water and / or wash liquor, which is not needed 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. Furthermore, the memory element 29 also in the area of the drainage line 25 be arranged to collect the drainage water there. As a result, a number of Abpumpvorgängen be reduced because, for example, in a cleaning process only once must be pumped. This would contribute to a temporal reduction of the cleaning process. It is also conceivable that the memory element 29 in front of the filter unit 27 is arranged and the water or the wash liquor from the tub 12 over the discharge opening 14 in the discharge line 14a passes before the filter unit 27 stores.

A cleaning process essentially comprises at least one wetting phase, at least one washing phase, at least one rinsing phase and at least one filter phase. The rinsing phase is again subdivided into at least one spin sequence and at least one rinsing sequence. How often one of the above phases is passed through is u.a. depending on the amount of laundry to be cleaned and the degree of soiling of the laundry as well as the selection of the cleaning program.

In the wetting phase, the laundry is wetted with water or washing liquor. This can be done via injection nozzles (not shown) and / or via the flushing line 19 respectively. The wetting phases can be repeated as often as desired. In the washing phase is under rotation of the receptacle 11 the laundry is circulated and washed. The soaked with wash lye is rinsed in the rinse phase, so that the wash is rinsed out of the laundry. This is usually done by several spin and rinse sequences.

Through each of the above phases, the laundry is in the receptacle 11 moved back and forth and thereby experiences friction caused by the rotation of the receptacle 11 or the wash liquor or the water is formed. In this case, the dust and dirt particles from the laundry, but also fibers, especially microplastic fibers are dissolved out of the laundry with. These fibers are environmentally damaging and contaminate the cleaning process. The dust and dirt particles and the fibers are removed from the filter unit 27 from the wash liquor or through the discharge opening 14 filtered out water filtered out. For this purpose, the above filter phases are provided.

In the filter phase, which can start as often as desired or which can be switched between the individual phases, the water and / or the wash liquor, which is in the tub 12 located from the pump unit 16 through the filter unit 27 pumped. The receptacle 11 is in a rest position during the filter phase, ie no mechanics or other kinetic energy acts on the receptacle 11 one. Preferably, no new wash liquor or water on the Einspülleitung 19 in the tub 12 introduced. The activation of the receptacle 11 via the control unit 21 , Preferably, the receptacle 11 braked along a predetermined braking curve according to a predeterminable reduction of the speed in the rest position. It is advantageous that the deceleration does not occur abruptly, so that very high frictional forces can act on the laundry. Preferably, the deceleration is as slow as possible, since thereby the least friction between the laundry and the receptacle 11 arises. An unnecessary extension of the cleaning process should be avoided.

Advantageously, a filter phase takes place after a washing and / or rinsing phase. As a result, fibers that have dissolved in the upstream washing and / or rinsing phase of the laundry, immediately removed from the cleaning process, so that, for example, a better cleaning result can be achieved. The more often a filter phase takes place, the lower is the amount of water or the wash water. Preferably, a filtering phase occurs after almost every washing and / or rinsing phase or even after each washing and / or rinsing phase. It is important that a reasonable amount of filter phases should be selected, so that although the cleaning result is optimal, the duration of the cleaning process does not increase to infinity.

It is also conceivable that the filter phase takes place before the washing and / or rinsing phase or in an interruption of the washing and / or rinsing phase. This has the advantage that the cleaning process does not have to be greatly interrupted in order to implement at least one filter phase in the cleaning process. Applying the filter phase before a washing and / or rinsing phase brings with it the advantage that the wash liquor or the water required for the subsequent phase is filtered immediately before being used again or further, and thus prepared particularly freshly the subsequent phase is initiated. Preferably, the filtering phase can be carried out in almost any, preferably in any interruption of the washing and / or rinsing phase.

In 4 is a schematic view of a household appliance 1 for treating laundry with a circulation principle. This is a schematic inside view of a dryer B , wherein individual components of the dryer are shown only greatly simplified.

The household appliance 1 in 4 , below a dryer B , also includes a receptacle 31 for laundry. Furthermore, the dryer includes B a filter unit 33 in a recirculation circuit of a recirculation unit 35 is arranged. The predominantly flowing fluid during the drying process is air. This may include moisture particles or be vaporous. The fluid is removed from the receptacle 31 through a discharge opening 36 in a discharge line 36a guided and by means of a pump unit 37 through the filter unit 33 pumped. In the filter unit 33 Dust particles and / or fibers, which detach from the laundry during the drying process, are dissolved out of the fluid. Via at least one recirculation line 39 the fluid is delivered via a feed opening 40 back into the receptacle 31 pumped. The discharge opening 36 is thus with the feed opening 40 fluidly connected. Furthermore, a memory element 45 the filter unit 33 be downstream. Analogous to the memory element 29 will also be in the memory element 45 stored the filtered fluid for a new or further drying process. If it is no longer needed, the fluid can flow through a drain line 44 be removed from the drying process. The pump unit 37 is via a control unit 41 driven. The control unit 41 also controls a drive unit 43 on, with the drive unit 43 the receptacle 31 drives. The pump unit 37 includes 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. In the spin phase are the in the receptacle 31 contained laundry moisture off. This moisture is via a discharge opening 36 from the receptacle 31 of the dryer B pumped out. In the drying phase warm air usually enters the receptacle 31 to dry the wet laundry. In both phases, fibers dissolve out of the laundry. Similar to the waxing process, these fibers must be removed from the drying process. The fibers as well as the air, which is contaminated with moisture particles, passes through the filter unit 33 pumped.

Analogous to the filter phase in the cleaning process is the receptacle 31 during a filter phase in the drying process in a rest position. A filter phase may preferably take place after a spin and / or drying phase, preferably after almost any, preferably after each spin and / or drying phase. It is also conceivable here that the filter phase takes place before the spinning and / or drying phase, preferably before virtually any, preferably before each spin and / or drying phase. The filtering phase can also take place in an interruption of the drying process, preferably in almost every interruption, preferably in every interruption.

After flowing through the filter unit 27 . 33 is conceivable both during the cleaning process and during the drying process, that the fluid either in the drain line 25 . 44 if one is present or in a recirculation line 15 . 43 that are in the recirculation unit 10 . 35 is arranged, is pumped. The recirculation line 15 . 43 directs the fluid back into the receptacle 31 and is used there for the continuation of the cleaning or drying process. If the fluid is no longer needed for the current cleaning or drying process, or if the cleaning or drying process is already completed, the fluid in a storage element 29 . 45 stored or cached for a new drying process.

By a recirculation unit 10 . 35 For example, less fluid is required for a cleaning or drying process, since the already existing fluid, ie 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 a lower consumption of water and / or detergent. In a dryer B For example, less warm or hot process air must be generated, which saves energy costs.

In the following, a sequence of a cleaning and drying process is shown greatly simplified until a filter phase takes place.

The cleaning process with a washing machine A is started, water and a mixture of water and detergent flows into the container and wets the laundry there. The wetting of the laundry can be done several times in pumping systems. It is also conceivable that after several wetting phases, a filter phase already takes place. Following the wetting phase, the washing phase is coupled. The receptacle 11 rotates thereby, so that the laundry is circulated repeatedly. In this process, in addition to the dust and dirt particles and fibers from the laundry solve. Advantageously, after a washing phase, after almost every or every washing phase, a filtering phase can take place in order to remove the fibers from the cleaning process.

In the filter phase, the wash liquor flows through the discharge opening 14 from the tub 12 in the discharge line 14a , The pump unit 16 pumps the wash liquor to or through the filter unit 27 in which, among other things, the fibers are filtered out of the wash liquor. Subsequently, the wash liquor is either in the storage element 29 pumped and stored there until it is needed for the current or another cleaning operations. About the recirculation unit 10 the wash solution returns to the receptacle 11 or in the tub 12 , If, for various reasons, the wash liquor is no longer suitable for further use, it can after passing through the filter unit 27 also in the drainage line 25 be pumped.

However, before the filter phase takes place, the receptacle must 11 be stopped so that it is in a rest position, ie the receptacle 11 does not move anymore. Now it is like that, the receptacle 11 in the upstream phase, here washing phase, moves. An abrupt deceleration, as in the case of a comparatively blender, which essentially starts at two positions "on" or "off", should be avoided, since further fibers detach from the laundry, as described in detail above. Therefore, it is advantageous if the receptacle 11 is braked along a predetermined braking curve according to a predeterminable reduction in speed. The slower the deceleration, the less fibers are released from the laundry.

In the following, the sake of completeness, a drying process in a household appliance according to the invention 1 , a dryer B , to be discribed.

The wet laundry is in the receptacle 31 circulated and with warm air, process air, applied. Among other things, fibers from the laundry dissolve. The mixture of moist air and fibers is removed from the receptacle 31 pumped out and to the filter unit 33 pumped. There, the mixture of moist air and fibers is filtered and can be used either analogously to the above-described cleaning process or in the drain line 44 be pumped. For further use, it is necessary that the air is removed from the air or the air is dried.

Advantageously, a filter phase takes place after one of the abovementioned phases of the cleaning or drying process. However, it is also conceivable that the filtering phase takes place after almost every phase or after each phase of the cleaning or drying process.

During a cleaning or drying process, there may be interruptions. Therefore, it is also conceivable to use these interruptions for a filter phase, so as not to prolong the cleaning or drying process. Preferably, almost any and / or every interrupt may be used for a filtering phase.

It is also conceivable that a filter phase takes place before a phase of the cleaning or drying process. Preferably, a filtering phase may occur almost before or before each phase of the cleaning or drying operation.
