Abstract

Die Erfindung schlägt vor, beispielsweise eine Waschmaschine (1) mit einem Flusensieb (14) und einem Mikroplastikfilter (15) auszurüsten, die anstelle eines ursprünglich vorgesehenen Flusensiebs in der Waschmaschine (1) untergebracht und zum Reinigen durch eine Öffnung (13) am Boden einer Vorderwand (9) der Waschmaschine (1) entnehmbar sind, die zur Entnahme des ursprünglichen Flusensiebs vorhanden ist.The invention proposes, for example, equipping a washing machine (1) with a lint filter (14) and a microplastic filter (15), which are housed in the washing machine (1) instead of an originally intended lint filter and for cleaning through an opening (13) at the bottom of a Front wall (9) of the washing machine (1) can be removed, which is available for removing the original lint filter.

Description

Die Erfindung betrifft ein Wäschebehandlungsgerät wie beispielsweise einen Wäschetrockner oder eine Waschmaschine mit den Merkmalen des Oberbegriffs des Anspruchs 1.The invention relates to a laundry treatment device such as a tumble dryer or a washing machine with the features of the preamble of claim 1.

Waschmaschinen und Wäschetrockner weisen typischerweise ein sogenanntes Flusensieb auf, das Fasern, Fusseln, Flusen und dergleichen, die sich während des Waschens oder Trocknens von Wäschestücken lösen, beim Abpumpen aus der Waschlauge oder beim Trocknen aus der Trocknungsluft siebt. Als Fasern, Fusseln, Flusen und dergleichen werden hier Partikel mit einer Länge von einem oder einigen Millimetern angesehen.Washing machines and tumble dryers typically have a so-called lint filter, which filters fibers, lint, lint and the like that come off items of laundry during washing or drying, from the washing solution when pumped out or from the drying air during drying. Fibers, lint, lint and the like are considered here to be particles with a length of one or a few millimeters.

Um zu vermeiden, dass Mikroplastik, das sich beim Waschen von Kunstfasern aufweisenden Wäschestücken löst, mit der Waschlauge abgepumpt wird, oder um Mikroplastik aus der Trocknungsluft zu sieben, schlägt die Offenlegungsschrift DE 10 2017 215 132 A1 eine Waschmaschine mit einem Mikroplastikfilter in einer Abflussleitung der Waschmaschine oder einen Wäschetrockner mit einem Mikroplastikfilter in einer Umluftleitung, die Luft als Trocknungsluft aus einer Wäschetrommel zur Wäschetrommel zurückführt, vor.In order to avoid microplastics that come off when washing items containing synthetic fibers, they are pumped out with the washing solution, or to sieve microplastics out of the drying air, the publication suggests DE 10 2017 215 132 A1 a washing machine with a microplastic filter in a drain line of the washing machine or a tumble dryer with a microplastic filter in a circulating air line that returns air as drying air from a laundry drum to the laundry drum.

Mikroplastik sind Teilchen, die an sich kleiner sind als Fasern, Fusseln, Flusen und dergleichen, und die, anders als Fasern, Fusseln, Flusen und dergleichen, großenteils das Flusensieb einer Waschmaschine oder eines Wäschetrockners überwinden. Dabei gibt es einen Überschneidungsbereich zwischen Fasern, Fusseln, Flusen und dergleichen einerseits und Mikroplastik andererseits. Unter Mikroplastik sollen hier Teilchen aus Kunststoff verstanden werden, die sich beim Waschen in einer Waschmaschine von Wäschestücken lösen, die Kunstfasern aufweisen und die eine Länge zwischen 50 µm und 5 Millimeter und eine Dicke oder einen Durchmesser von nicht mehr als 10 µm aufweisen. Ein Mikroplastikfilter ist dementsprechend ein Filter, das mindestens 80 bis 90 % des Mikroplastik aus der Waschlauge, der Trocknungsluft oder allgemein aus einem Fluid filtert. Ein Mikroplastikfilter weist eine Maschenweite oder Porengröße von beispielsweise zwischen 5 und 200 µm auf.Microplastics are particles that are inherently smaller than fibers, lint, lint, and the like, and which, unlike fibers, lint, lint, and the like, largely overcome the lint filter of a washing machine or tumble dryer. There is an area of overlap between fibers, lint, fluff and the like on the one hand and microplastics on the other. Microplastics are understood here to mean plastic particles that come off of items of laundry when washed in a washing machine that contain synthetic fibers and have a length of between 50 µm and 5 millimeters and a thickness or diameter of no more than 10 µm. A microplastic filter is therefore a filter that filters at least 80 to 90% of the microplastics from the wash liquor, the drying air or generally from a fluid. A microplastic filter has a mesh size or pore size of, for example, between 5 and 200 µm.

Aufgabe der Erfindung ist, ein Wäschebehandlungsgerät wie beispielsweise eine Waschmaschine oder einen Wäschetrockner mit einer verbesserten Reinigungswirkung vorzuschlagen, das von einem Verbraucher einfach zu reinigen ist.The object of the invention is to propose a laundry treatment device such as a washing machine or a tumble dryer with an improved cleaning effect that is easy to clean by a consumer.

Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruchs 1 gelöst. Die abhängigen Ansprüche haben vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung zum Gegenstand.This object is achieved according to the invention by the features of claim 1. The dependent claims relate to advantageous refinements and developments of the invention.

Das erfindungsgemäße Wäschebehandlungsgerät weist ein Gehäuse und einen in dem Gehäuse angeordneten Wäschebehälter zur Aufnahme von zu behandelnden Wäschestücken auf. Der Wäschebehälter ist insbesondere eine drehbar in dem Gehäuse angeordnete und mit einem Elektromotor oder in anderer Weise drehend antreibbare Wäschetrommel. An den Wäschebehälter ist eine Luftleitung oder eine Wasserleitung angeschlossen, durch die Luft, ein Gas, Wasser, eine Flüssigkeit oder allgemein ein Fluid aus dem Wäschebehälter ausströmt. In der Luftleitung oder der Wasserleitung ist erfindungsgemäß ein Flusensieb, das Fasern, Fusseln, Flusen und dergleichen, und ein Mikroplastikfilter, das Mikroplastik aus dem die Luftleitung oder Wasserleitung durchströmenden Fluid filtert, angeordnet. Vorzugsweise ist das Flusensieb in einer Durchströmungsrichtung durch die Luftleitung oder durch die Wasserleitung vor dem Mikroplastikfilter angeordnet. Das Mikroplastikfilter filtert kleinere Teilchen aus der Luft, dem Wasser oder allgemein aus dem Fluid als das Flusensieb beziehungsweise das Mikroplastikfilter filtert Teilchen aus dem Fluid, die durch das Flusensieb hindurch gelangt sind. Das Flusensieb und das Mikroplastikfilter sind erfindungsgemäß innerhalb des Gehäuses des Wäschebehandlungsgeräts angeordnet.The laundry treatment device according to the invention has a housing and a laundry container arranged in the housing for receiving items of laundry to be treated. The laundry container is in particular a laundry drum that is rotatably arranged in the housing and can be driven in rotation with an electric motor or in another way. An air line or a water line is connected to the laundry container, through which air, a gas, water, a liquid or generally a fluid flows out of the laundry container. According to the invention, a lint filter, which filters fibers, lint, lint and the like, and a microplastic filter, which filters microplastics from the fluid flowing through the air pipe or water pipe, are arranged in the air pipe or the water pipe. Preferably, the lint filter is in a flow direction through the air line or arranged through the water pipe in front of the microplastic filter. The microplastic filter filters smaller particles from the air, the water or generally from the fluid than the lint filter or the microplastic filter filters particles from the fluid that have passed through the lint filter. According to the invention, the lint filter and the microplastic filter are arranged within the housing of the laundry treatment device.

Durch die Hintereinanderschaltung des Flusensiebs und des Mikroplastikfilters ist eine Filterwirkung des erfindungsgemäßen Wäschebehandlungsgeräts verbessert und das Mikroplastikfilter vermeidet weitgehend, dass Mikroplastik, das sich beim Trocknen, Waschen oder allgemein Behandeln von Wäschestücken in dem Wäschebehälter des erfindungsgemäßen Wäschebehandlungsgeräts löst, in die Umwelt gelangt. Das Flusensieb hält das Mikroplastikfilter von größeren Teilchen frei. Durch die Anordnung innerhalb des Gehäuses des Wäschebehandlungsgeräts müssen das Flusensieb und/oder das Mikroplastikfilter nicht separat außerhalb des Wäschebehandlungsgeräts angebracht und angeschlossen werden, sondern das Wäschebehandlungsgerät kann von vornherein mit dem Flusensieb und dem Mikroplastikfilter ausgerüstet und in Verkehr gebracht werden. Auch lässt sich das erfindungsgemäße Wäschebehandlungsgerät so ausbilden, dass ein Betrieb ohne das Mikroplastikfilter ausgeschlossen ist, um einen Betrieb ohne Mikroplastikfilter zu verhindern.By connecting the lint filter and the microplastic filter in series, a filter effect of the laundry treatment device according to the invention is improved and the microplastic filter largely prevents microplastics, which dissolve during drying, washing or general treatment of laundry items in the laundry container of the laundry treatment device according to the invention, from getting into the environment. The lint filter keeps the microplastic filter free of larger particles. Due to the arrangement within the housing of the laundry treatment device, the lint filter and / or the microplastic filter do not have to be attached and connected separately outside the laundry treatment device, but the laundry treatment device can be equipped with the lint filter and the microplastic filter from the outset and placed on the market. The laundry treatment device according to the invention can also be designed in such a way that operation without the microplastic filter is excluded in order to prevent operation without the microplastic filter.

Eine Ausgestaltung der Erfindung sieht eine Öffnung im Gehäuse des Wäschebehandlungsgeräts vor, durch die sowohl das Flusensieb als auch das Mikroplastikfilter zur Reinigung oder zum Austausch entnehmbar und wieder in das Wäschebehandlungsgerät einsetzbar sind. Es handelt sich insbesondere um eine Öffnung, die bei einem herkömmlichen Wäschebehandlungsgerät zum Entnehmen eines Flusensiebs vorhanden ist, so dass insoweit keine baulichen Änderungen vorgenommen werden müssen. Die Öffnung ist insbesondere in einer Vorderwand des Gehäuses des Wäschebehandlungsgeräts vorgesehen. Die Vorderwand weist insbesondere auch eine Öffnung, durch die Wäschestücke in den Wäschebehälter einbringbar sind, und eine Anzeige/n und/oder Bedienelement/e auf. Die Vorderwand ist zugänglich, wenn das Wäschebehandlungsgerät wie vorgesehen aufgestellt ist, so dass das Flusensieb und das Mikroplastikfilter gut zugänglich sind.One embodiment of the invention provides an opening in the housing of the laundry treatment device, through which both the lint filter and the microplastic filter can be removed for cleaning or replacement and reinserted into the laundry treatment device. In particular, it is an opening that is present in a conventional laundry treatment device for removing a lint filter, so that no structural changes need to be made. The opening is provided in particular in a front wall of the housing of the laundry treatment device. The front wall in particular also has an opening through which items of laundry can be placed in the laundry container can be inserted, and a display/s and/or control element/s. The front wall is accessible when the laundry treatment device is set up as intended so that the lint filter and the microplastic filter are easily accessible.

In bevorzugter Ausgestaltung sind das Flusensieb und das Mikroplastikfilter miteinander verbunden, derart dass sie als Einheit handhabbar und zur Reinigung oder zum Wechsel als Ganzes aus dem Wäschebehandlungsgerät entnehmbar und auch wieder einsetzbar sind. Das vereinfacht eine Handhabung des Flusensiebs und des Mikroplastikfilters zu ihrer Reinigung oder zu ihrem Ersatz. Das Mikroplastikfilter kann beispielsweise zum Reinigen von dem Flusensieb lösbar sein. Beispielsweise sind das Mikroplastikfilter und das Flusensieb zusammengesteckt, zusammengeschraubt, das heißt sie weisen eine Steckverbindung, eine Schraubverbindung oder einen Bajonettverschluss zu ihrer lösbaren Verbindung aus. Die Verbindung ist vorzugsweise manuell ohne Werkzeug lösbar.In a preferred embodiment, the lint filter and the microplastic filter are connected to one another in such a way that they can be handled as a unit and can be removed as a whole from the laundry treatment device for cleaning or changing and can also be used again. This makes it easier to handle the lint filter and the microplastic filter for cleaning or replacing them. The microplastic filter can, for example, be detachable from the lint filter for cleaning. For example, the microplastic filter and the lint filter are plugged together, screwed together, that is, they have a plug connection, a screw connection or a bayonet connection for their releasable connection. The connection can preferably be released manually without tools.

Vorzugsweise ist das Mikroplastikfilter in einem Filtergehäuse untergebracht beziehungsweise angeordnet, in dem auch das Flusensieb angeordnet ist. Und zwar handelt es sich insbesondere um ein Filtergehäuse, das das Wäschebehandlungsgerät bereits ursprünglich für ein Flusensieb aufweist. Ein ursprüngliches Flusensieb muss gegebenenfalls ersetzt werden durch ein Flusensieb, das die Unterbringung zusammen mit dem Mikroplastikfilter in dem ursprünglich nur für das Flusensieb vorgesehenen Filtergehäuse ermöglicht und/oder durch ein Flusensieb, das mit dem Mikroplastikfilter verbunden oder verbindbar ist.The microplastic filter is preferably housed or arranged in a filter housing in which the lint filter is also arranged. In particular, it is a filter housing that the laundry treatment device originally has for a lint filter. An original lint filter may need to be replaced by a lint filter that allows it to be accommodated together with the microplastic filter in the filter housing originally intended only for the lint filter and/or by a lint filter that is connected or connectable to the microplastic filter.

Eine Ausgestaltung der Erfindung sieht einen Filterkorb als eine Art Stützgerüst für das Mikroplastikfilter vor. Ein Filtermaterial ist, je nach Durchströmungsrichtung in oder außen an dem Filterkorb angeordnet: wird der Filterkorb von innen nach au-ßen durchströmt, befindet sich das Filtermaterial vorzugsweise innen und wird von der Durchströmung an den Filterkorb gedrückt und von dem Filterkorb gegen die Durchströmung gestützt. Wird der Filterkorb von außen nach innen durchströmt, wird das Filtermaterial vorzugsweise außen angeordnet, damit die Durchströmung das Filtermaterial gegen den Filterkorb drückt. Zum Reinigen und/oder Wechseln lässt sich das Filtermaterial vorzugsweise aus dem Filterkorb entnehmen oder vom Filterkorb abnehmen.One embodiment of the invention provides a filter basket as a type of support structure for the microplastic filter. A filter material is arranged inside or outside of the filter basket, depending on the flow direction: if the flow flows through the filter basket from the inside to the outside, the filter material is preferably located on the inside and is pressed against the filter basket by the flow and is supported by the filter basket against the flow. If the filter basket is flowed through from the outside to the inside, the filter material is preferably arranged on the outside so that the flow presses the filter material against the filter basket. For cleaning and/or changing The filter material can preferably be removed from the filter basket or removed from the filter basket.

Die Formen des Gehäuses 3, des Wäschebehälters 5 und des Laugenbehälters 7 und ihre Anordnung im Gehäuse 3 der das Wäschebehandlungsgerät 2 bildenden Waschmaschine 1 sind nicht zwingend für die Erfindung.The shapes of the housing 3, the laundry container 5 and the tub 7 and their arrangement in the housing 3 of the washing machine 1 forming the laundry treatment device 2 are not mandatory for the invention.

Das Flusensieb 14 und das Mikroplastikfilter 15 filtern eine Waschlauge, die nach einem Waschen mit einer Laugenpumpe 16 aus dem Laugenbehälter 7 abgepumpt wird, bevor die Waschlauge in einen Abfluss gelangt. Dazu sind das Flusensieb 14, das Mikroplastikfilter 15 und die Laugenpumpe 16 - in der genannten Reihenfolge - in einer Abflussleitung 17 angeordnet, die von dem Laugenbehälter 7 zu einer Rückwand 18 des Gehäuses 3 der Waschmaschine 1 führt und dort mit einem nicht dargestellten Schlauch an den ebenfalls nicht dargestellten Abfluss beispielsweise einer Sanitärinstallation eines Gebäudes angeschlossen wird. Die Abflussleitung 17 kann allgemein auch als Wasserleitung 19 aufgefasst werden.The lint filter 14 and the microplastic filter 15 filter a wash liquor, which is pumped out of the tub 7 after washing with a drain pump 16 before the wash liquor goes into a drain. For this purpose, the lint filter 14, the microplastic filter 15 and the drain pump 16 - in the order mentioned - are arranged in a drain line 17, which leads from the tub 7 to a rear wall 18 of the housing 3 of the washing machine 1 and there with a not The hose shown is connected to the drain, also not shown, for example of a plumbing installation in a building. The drain line 17 can generally also be understood as a water line 19.

Erfindungsgemäß sind das Flusensieb 14 und das Mikroplastikfilter 15 in einem Filtergehäuse 20 untergebracht, an das die Laugenpumpe 16 durch einen mittleren Abschnitt der Abflussleitung 17 / Wasserleitung 19 oder in anderer Weise angeschlossen ist. Das Filtergehäuse 20 ist in der die Wasserleitung 19 bildenden Abflussleitung 17 angeordnet, das heißt ein erster Abschnitt der Abflussleitung 17 führt von dem Laugenbehälter 7 zu dem Filtergehäuse 20, der mittlere Abschnitt der Abflussleitung 17 verbindet die Laugenpumpe 16 mit dem Filtergehäuse 20 und ein letzter Abschnitt der Abflussleitung 17 führt von der Laugenpumpe 16 zur Rückwand 18 des Gehäuses 3 der Waschmaschine 1. Das bedeutet, dass das Flusensieb 14 und das Mikroplastikfilter 15 erfindungsgemäß in der Waschmaschine 1, das heißt innerhalb des Gehäuses 3 der Waschmaschine 1 untergebracht sind.According to the invention, the lint filter 14 and the microplastic filter 15 are housed in a filter housing 20, to which the drain pump 16 is connected through a central section of the drain line 17/water line 19 or in another way. The filter housing 20 is arranged in the drain line 17 forming the water line 19, that is to say a first section of the drain line 17 leads from the tub 7 to the filter housing 20, the middle section of the drain line 17 connects the drain pump 16 to the filter housing 20 and a final section The drain line 17 leads from the drain pump 16 to the rear wall 18 of the housing 3 of the washing machine 1. This means that the lint filter 14 and the microplastic filter 15 are accommodated according to the invention in the washing machine 1, that is, within the housing 3 of the washing machine 1.

Im Filtergehäuse 20 durchströmt die Waschlauge aus dem Laugenbehälter 7 zuerst das Flusensieb 14, dann das Mikroplastikfilter 15 und wird nach dem Mikroplastikfilter 15 von der Laugenpumpe 16 abgesaugt.In the filter housing 20, the washing liquor from the tub 7 first flows through the lint filter 14, then the microplastic filter 15 and is sucked off by the drain pump 16 after the microplastic filter 15.

Das Filtergehäuse 20 der erfindungsgemäßen Waschmaschine 1 weist die Abmessung eines nicht dargestellten Flusensiebgehäuses eines Flusensiebs auf, das ursprünglich in der Waschmaschine 1 vorhanden oder jedenfalls in der Waschmaschine 1 vorgesehen war. Anders ausgedrückt weist das Filtergehäuse 20 der erfindungsgemäßen Waschmaschine 1 Standardeinbaumaße des ursprünglich vorgesehenen Flusensiebgehäuses auf, das Flusensieb 14 und das Mikroplastikfilter 15 sind in dem Filtergehäuse 20 an der Stelle des ursprünglich vorgesehenen Flusensiebs in der Waschmaschine 1 angeordnet.The filter housing 20 of the washing machine 1 according to the invention has the dimensions of a lint filter housing, not shown, of a lint filter, which was originally present in the washing machine 1 or was at least provided in the washing machine 1. In other words, the filter housing 20 of the washing machine 1 according to the invention has standard installation dimensions of the originally intended lint filter housing, the lint filter 14 and the microplastic filter 15 are arranged in the filter housing 20 at the location of the originally intended lint filter in the washing machine 1.

Die von dem Laugenbehälter 7 kommende, die Wasserleitung 19 bildende Abflussleitung 17 ist an der Stelle des Filtergehäuses 20 der erfindungsgemäßen Waschmaschine 1 angeordnet beziehungsweise angeschlossen, an der die Abflussleitung der Waschmaschine 1 ursprünglich an das ursprüngliche Gehäuse des ursprünglichen Flusensiebs angeschlossen war. An der Laugenpumpe 16 ist die die Wasserleitung 19 bildende Abflussleitung 17 der erfindungsgemäßen Waschmaschine 1 ebenso an der Stelle angeschlossen, an der sie auch ursprünglich an die oder an eine ersetzte Laugenpumpe angeschlossen war. Das Filtergehäuse 20, in dem das Flusensieb 14 und das Mikroplastikfilter 15 in der erfindungsgemäßen Waschmaschine 1 untergebracht sind, ist jedenfalls so konstruiert, dass es in einen Einbauraum der Waschmaschine 1 passt, der ursprünglich für ein Flusensiebgehäuse eines ursprünglich dort vorgesehenen Flusensiebs ohne Mikroplastikfilter vorgesehen war.The drain line 17 coming from the tub 7 and forming the water line 19 is arranged or connected at the location of the filter housing 20 of the washing machine 1 according to the invention, at which the drain line the washing machine 1 was originally connected to the original housing of the original lint filter. The drain line 17 of the washing machine 1 according to the invention, which forms the water line 19, is also connected to the drain pump 16 at the point where it was originally connected to the drain pump or to a replaced drain pump. The filter housing 20, in which the lint filter 14 and the microplastic filter 15 are accommodated in the washing machine 1 according to the invention, is in any case constructed in such a way that it fits into an installation space of the washing machine 1, which was originally intended for a lint filter housing of a lint filter originally provided there without a microplastic filter .

Das Flusensieb 14 hält Fasern, Fusseln, Flusen und dergleichen, die sich während des Waschens von Wäschestücken lösen, zurück und hält sie von dem Mikroplastikfilter 15 und der Laugenpumpe 16 fern. Das Flusensieb 14 hält auch größere Teile wie Büroklammern, Sicherheitsnadeln, Münzen und was auch immer in die Waschlauge gelangt, vom Mikroplastikfilter 15 und von der Laugenpumpe 16 fern.The lint filter 14 holds back fibers, lint, fluff and the like that come off items of laundry during washing and keeps them away from the microplastic filter 15 and the drain pump 16. The lint filter 14 also keeps larger parts such as paper clips, safety pins, coins and whatever gets into the washing water away from the microplastic filter 15 and the drain pump 16.

Das Mikroplastikfilter 15 filtert Mikroplastik, das heißt Teilchen aus Kunststoff, die sich beim Waschen in der Waschmaschine 1 von Wäschestücken, die Kunstfasern aufweisen, lösen und die eine Länge zwischen 50 µm und 5 Millimeter und eine Dicke oder einen Durchmesser von nicht mehr als 10 µm aufweisen und die das Flusensieb 14 überwunden haben, aus der Waschlauge, bevor die Waschlauge in den Abfluss und damit in die Umwelt gelangt. Das Mikroplastikfilter 15 ist dementsprechend ein Filter, das mindestens 80 bis 90 % des Mikroplastik aus der Waschlauge filtert.The microplastic filter 15 filters microplastics, that is, particles made of plastic that come off of items of laundry containing synthetic fibers when washed in the washing machine 1 and that have a length between 50 μm and 5 millimeters and a thickness or a diameter of no more than 10 μm have and which have overcome the lint filter 14, from the wash liquor before the wash liquor gets into the drain and thus into the environment. The microplastic filter 15 is accordingly a filter that filters at least 80 to 90% of the microplastics from the wash liquor.

Als Filtermedium 21 weist das Mikroplastikfilter 15 im Ausführungsbeispiel der Erfindung einen Filterbeutel 22 auf, der aus einem thermofixierten Kunststoffsiebgewebe mit einer mittleren Maschenweite im Bereich zwischen 5 µm und 200 µm hergestellt ist.As a filter medium 21, the microplastic filter 15 in the exemplary embodiment of the invention has a filter bag 22, which is made from a heat-set plastic sieve fabric with an average mesh size in the range between 5 μm and 200 μm.

Der Filterbeutel 21 ist in einem siebartigen Filterkorb 22 angeordnet, der im Ausführungsbeispiel zylinderrohrförmig ist und der zusammen mit dem Filterbeutel 21 das Mikroplastikfilter 15 bildet (Figur 3).The filter bag 21 is arranged in a sieve-like filter basket 22, which in the exemplary embodiment is cylindrical tube-shaped and which, together with the filter bag 21, forms the microplastic filter 15 ( Figure 3 ).

Das Flusensieb 14 und das Mikroplastikfilter 15 sind zusammengesteckt derart, dass die Waschlauge, die aus dem Laugenbehälter 7 in und durch das Flusensieb 14 strömt, aus dem Flusensieb 14 in das Mikroplastikfilter 15, das heißt in und durch den aus dem Filtermedium 22 bestehenden Filterbeutel 21 strömt. Eine Steckverbindung ist in Figur 3 mit der Bezugszahl 25 versehen. Das Flusensieb 14 und das Mikroplastikfilter 15 können auch in anderer Weise als durch Stecken lösbar miteinander verbunden sein, beispielsweise durch Verschrauben, das heißt mit einer Schraubverbindung oder mit einem Bajonettverschluss. Durch ihre Verbindung sind das Flusensieb 14 und das Mikroplastikfilter 15 als Einheit zusammen handhabbar.The lint filter 14 and the microplastic filter 15 are put together in such a way that the washing liquor, which flows from the tub 7 into and through the lint filter 14, from the lint filter 14 into the microplastic filter 15, that is, into and through the filter bag 21 consisting of the filter medium 22 flows. A plug connection is in Figure 3 provided with the reference number 25. The lint filter 14 and the microplastic filter 15 can also be releasably connected to one another in a way other than plugging, for example by screwing, that is, with a screw connection or with a bayonet lock. Due to their connection, the lint filter 14 and the microplastic filter 15 can be handled together as a unit.

Das Flusensieb 14 weist einen Deckel 24 auf, der eine Öffnung des Filtergehäuses 20 wasserdicht verschließt. Der Deckel 24 befindet sich in der Öffnung 13 in der Vorderwand 9 des Gehäuses 3 der Waschmaschine 1. Dadurch lassen sich das Flusensieb 14 und das Mikroplastikfilter 15 zum Reinigen oder auch zum Ersatz einfach und ohne Werkzeug durch die Öffnung 13 in der Vorderwand 9 des Gehäuses 3 aus der Waschmaschine 1 entnehmen, das Mikroplastikfilter 15 vom Flusensieb 14 lösen, der Filterbeutel 21 aus dem Filterkorb 23 entnehmen, reinigen, waschen oder ersetzen und nach dem Reinigen oder Ersatz in umgekehrter Reihenfolge wieder in die Waschmaschine 1 einbringen. Die Öffnung 13 befindet sich an der Stelle in der Vorderwand 6 des Gehäuses 7 der Waschmaschine 1, an der sich eine Öffnung des ersetzten Flusensiebgehäuses des Flusensiebs befunden hat beziehungsweise befinden würde.The lint filter 14 has a lid 24 which closes an opening of the filter housing 20 in a watertight manner. The cover 24 is located in the opening 13 in the front wall 9 of the housing 3 of the washing machine 1. This allows the lint filter 14 and the microplastic filter 15 to be cleaned or replaced easily and without tools through the opening 13 in the front wall 9 of the housing 3 from the washing machine 1, remove the microplastic filter 15 from the lint filter 14, remove the filter bag 21 from the filter basket 23, clean, wash or replace it and, after cleaning or replacing it, put it back into the washing machine 1 in the reverse order. The opening 13 is located at the point in the front wall 6 of the housing 7 of the washing machine 1 where an opening of the replaced lint filter housing of the lint filter was or would be located.

Die Waschlauge aus dem Mikroplastikfilter 15 beziehungsweise aus dem Filterbeutel 21 des Mikroplastikfilters 15 darf nicht einfach in den Abfluss der Sanitärinstallation des Gebäudes gelehrt werden, weil sonst das Mikroplastik doch in die Kanalisation und durch die Kanalisation in die Umwelt gelangen würde. Das Mikroplastik aus dem Mikroplastikfilter 15 beziehungsweise aus dem Filterbeutel 21 muss sachgerecht entsorgt werden.The washing liquor from the microplastic filter 15 or from the filter bag 21 of the microplastic filter 15 must not simply be poured into the drain of the building's sanitary installation, because otherwise the microplastic would end up in the sewer system and through the sewer system into the environment. The microplastics from the microplastic filter 15 or from the filter bag 21 must be disposed of properly.

Eine normalerweise in Waschmaschinen 1 vorhandene elektronische Kontrolle einer Verschmutzung des Flusensiebs funktioniert auch für das erfindungsgemäß mit dem Flusensieb 14 kombinierte Mikroplastikfilter 15. Die Kontrolle misst typischerweise eine zum Abpumpen der Waschlauge aus dem Laugenbehälter 7 erforderliche Abpumpdauer und zeigt - typischerweise mit einer Kontrollleuchte oder in der Anzeige 12 - eine Verschmutzung des Flusensiebs an, wenn die Abpumpdauer einen vorgegebenen Wert übersteigt. Auch mit einer Messung eines Drucks der Waschlauge am Einlass des Flusensiebs beim Abpumpen ist eine Kontrolle der Verschmutzung möglich. Diese ursprünglich für das Flusensieb der Waschmaschine 1 vorgesehene Kontrolle funktioniert auch für das erfindungsgemäße Mikroplastikfilter 15 zusammen mit dem in der Durchströmungsrichtung vorgeschalteten Flusensieb 14, ohne dass es einer Änderung bedarf.An electronic control of contamination of the lint filter, which is normally present in washing machines 1, also works for the microplastic filter 15 combined with the lint filter 14 according to the invention. The control typically measures the pumping time required to pump out the washing suds from the tub 7 and shows - typically with an indicator light or in the Display 12 - indicates that the lint filter is dirty if the pumping time exceeds a specified value. It is also possible to check the contamination by measuring the pressure of the washing solution at the inlet of the lint filter when pumping out. This control, originally intended for the lint filter of the washing machine 1, also works for the microplastic filter 15 according to the invention together with the lint filter 14 upstream in the flow direction, without any change being necessary.
