Description

Die Erfindung liegt auf dem Gebiet der Wäschebehandlungsmaschinen, wie insbesondere Wäschetrockner oder Kombinationsgeräte, sogenannte Waschtrockner, und betrifft eine Wäschebehandlungsmaschine, die eine derartige Filtervorrichtung enthält.The invention is in the field of laundry treatment machines, such as in particular tumble dryers or combination devices, so-called washer-dryers, and relates to a laundry treatment machine that contains such a filter device.

Derartige Filtervorrichtungen sind beispielsweise aus der DE 10 2014 225 905 A1 oder der WO 2015/89085 A1 bekannt.Such filter devices are, for example, from DE 10 2014 225 905 A1 or the WO 2015/89085 A1 known.

Die EP 2 455 537 A1 beschreibt einen Wäschetrockner mit einer in einem Gehäuse drehbar gelagerten Trommel, einer durch eine Tür verschließbare Beschickungsöffnung sowie einem Gebläse und einer Heizeinrichtung zur Erzeugung eines Prozessluftstroms, der über einen Wärmetauscher strömt. Das Gehäuse weist in seiner Frontwand eine Revisionsklappe auf, durch die eine Filtervorrichtung zugänglich ist. Die Filtervorrichtung ist entlang des Prozessluftstroms, also in Richtung des fließenden Prozessluftstroms gesehen, dem Wärmetauscher vorgeordnet und weist eine Filtereinrichtung mit einem entnehmbaren Filtereinsatz (Filterelement) auf.the EP 2 455 537 A1 describes a tumble dryer with a drum mounted rotatably in a housing, a loading opening that can be closed by a door, and a blower and a heating device for generating a process air stream that flows over a heat exchanger. In its front wall, the housing has an inspection flap through which a filter device is accessible. The filter device is arranged upstream of the heat exchanger along the process air flow, ie in the direction of the flowing process air flow, and has a filter device with a removable filter insert (filter element).

Die EP 2 801 653 A2 zeigt einen Wäschetrockner mit einer Revisionsklappe durch die ein Filterelement zur Reinigung zugänglich ist. Die Revisionsklappe ist mit einem Dichtungsprofil gegen das Gehäuse abgedichtet.the EP 2 801 653 A2 shows a tumble dryer with an inspection flap through which a filter element is accessible for cleaning. The inspection flap is sealed against the housing with a sealing profile.

Die EP 2 392 723 A2 zeigt einen Wäschetrockner mit in der Tür angeordneten Filterelementen, von denen ein erstes abklappbar und ein zweites dadurch entnehmbar ist.the EP 2 392 723 A2 shows a tumble dryer with filter elements arranged in the door, of which a first one can be folded down and a second one can be removed as a result.

Die WO 2013/178517 A1 zeigt einen Wäschetrockner mit zwei ineinander gesteckten Flusenfiltern, die in einer Ausnehmung in der Beladeöffnung des Trockners untergebracht sind. Die Öffnung wird von einer Dichtung abgedeckt, wenn die Filter entnommen sind, um Eindringen von Flusen in die Ausnehmung zu verhindern.the WO 2013/178517 A1 shows a tumble dryer with two nested lint filters, which are housed in a recess in the loading opening of the dryer. The opening is covered by a gasket when the filters are removed to prevent lint from entering the recess.

In der Wäschetrommel befindliche zu trocknende Wäsche wird während des Trocknungsvorganges von erwärmter Prozessluft überströmt, die dabei neben der Feuchtigkeit aus der Wäsche auch Haare, Fusseln, Waschmittelrückstände und dergleichen aufnimmt (nachfolgend zusammenfassend als Flusen oder Verunreinigungen bezeichnet) und diese mitführt. Diese Flusen setzen sich an dem Filtereinsatz ab, der zur Aufrechterhaltung einer ausreichenden Trocknungsleistung und zum Schutz der nachfolgenden Komponenten in regelmäßigen Abständen von dem Benutzer aus der Filtervorrichtung entnommen, gesäubert oder bedarfsweise ausgetauscht und wieder eingesetzt werden muß. Dabei können durch Schrumpfung und Abnutzung des Filterelements oder anderer Bauteile Lücken entstehen, die von Prozessluft bevorzugt durchströmt werden, mithin eine Bypasströmung ausbilden. Die dabei am Filter vorbei mittransportierten Flusen belasten die Wärmetauscher, insbesondere für Hochleistungswärmetauscher mit engem Lamellenabstand wird eine solche Belastung als kritisch angesehen.During the drying process, heated process air flows over the laundry to be dried in the laundry drum, which, in addition to the moisture from the laundry, also picks up hair, lint, detergent residues and the like (hereinafter collectively referred to as lint or dirt referred to) and carries them with you. This fluff settles on the filter insert, which has to be removed from the filter device by the user at regular intervals, cleaned or, if necessary, replaced and reinserted in order to maintain sufficient drying performance and to protect the downstream components. Shrinkage and wear of the filter element or other components can result in gaps through which process air preferably flows, thus forming a bypass flow. The fluff transported past the filter puts a strain on the heat exchanger. Such a load is considered critical, particularly for high-performance heat exchangers with narrow fin spacing.

Die Erfindung schafft eine Wäschebehandlungsmaschine mit einer Filtereinrichtung die einfach in den Prozeßluftkreislauf der Wäschebehandlungsmaschine eingebracht werden kann und eine Bypaßströmung am Filter vorbei wirksam unterbindet.The invention creates a laundry treatment machine with a filter device that can be easily introduced into the process air circuit of the laundry treatment machine and effectively prevents a bypass flow past the filter.

Gemäß eines ersten Aspektes der Erfindung ist eine Wäschebehandlungsmaschine mit den Merkmalen des unabhängigen Anspruchs vorgesehen.According to a first aspect of the invention, a laundry treatment machine having the features of the independent claim is provided.

Diese Gestaltung der Filtereinrichtung bietet eine axiale Abdichtung des Filterelements, also in Einsetzrichtung des Filterelements: Durch das Einsetzen wird der Schaum zwischen seinem Trägerbauteil und dem axialen Dichtsitz an dem Dichtungseinsatzes komprimiert und damit sicher in seiner Soll-Position fixiert. Der Dichtungseinsatz dichtet sich zum Umgebungsbauteil, dem Prozeßluftkanal, der zum Wärmetauscher führt, durch ein Dichtsystem in Form der radialen Dichtlippe ab und bietet gleichzeitig den axialen Dichtsitz für den Schaum.This design of the filter device offers axial sealing of the filter element, i.e. in the direction of insertion of the filter element: By inserting the foam between its carrier component and the axial sealing seat on the sealing insert is compressed and thus securely fixed in its desired position. The sealing insert is sealed to the surrounding component, the process air duct, which leads to the heat exchanger, by a sealing system in the form of the radial sealing lip and at the same time offers the axial sealing seat for the foam.

Um die Reaktionskräfte der Dichtlippe auf den Dichtungseinsatz zu harmonisieren, sodaß es insbesondere an den Ecken nicht zu einer Erhöhung der Reaktionskräfte kommt, sind in vorteilhaften Weiterbildungen Maßnahmen vorgesehen, beispielsweise kann die radialen Dichtlippe auf einem kurzen Stück komplett unterbrochen sein, die Wandstärke der radialen Dichtlippe abschnittsweise, verringert sein und/oder die Lippenhöhe variiert sein.In order to harmonize the reaction forces of the sealing lip on the sealing insert, so that there is no increase in the reaction forces, particularly at the corners, measures are provided in advantageous further developments, for example the radial sealing lip can be completely interrupted over a short distance, the wall thickness of the radial sealing lip in sections, be reduced and/or the lip height varied.

In einer vorteilhaften Ausführungsform ist bei der Filtervorrichtung an einer gegen die Strömungsrichtung weisenden Rückseite des Dichtungseinsatzes, umlaufend um eine Durchströmöffnung, eine axiale Halterippe ausgebildet. Dadurch wird verhindert, daß das Material des Filterelements sich von der Rückseite abhebt oder der Rand des Filterelements in die Durchströmöffnung rutscht und sich zwischen dem Filterelement und der Rückseite des Dichtungseinsatzes möglicherweise eine Bypaßströmung ausbilden kann. In einer weiteren vorteilhaften Ausführungsform ist bei der Filtervorrichtung an dem Dichtungseinsatz wenigstens ein Stützsteg vorgesehen ist, der die Durchströmöffnung in wenigstens zwei Teile teilt. Damit wird verhindert, daß das Filterelement unter der axialen Belastung durch den Prozeßluftstrom verformt, insbesondere ausgebeult wird.In an advantageous embodiment, an axial holding rib is formed in the filter device on a rear side of the sealing insert pointing against the direction of flow, surrounding a flow opening. This prevents the material of the filter element from lifting off the back or the edge of the filter element slips into the flow opening and a bypass flow can possibly form between the filter element and the back of the sealing insert. In a further advantageous embodiment, at least one support web is provided on the sealing insert in the filter device, which web divides the through-flow opening into at least two parts. This prevents the filter element from being deformed, in particular bulging, under the axial load caused by the process air flow.

In einer weiteren vorteilhaften Ausführungsform ist bei der Filtervorrichtung eine Auffangwanne zum Einschieben in eine Prozeßluftführung der Wäschebehandlungsmaschine aufweist, an welcher der Dichtungseinsatz schwenkbar gelagert ist. Dies erleichtert das Einsetzen des Dichtungseinsatzes, der damit nicht separat handzuhaben ist, sondern beim Einschieben der Auffangwanne in seine Position gebracht werden kann. Insbesondere vorteilhaft kann an der Bodengruppe des Wäschebehandlungsgerätes im Bereich des Prozeßluftkanals eine schräg nach oben gerichtete Rampenkante ausgebildet sein, an der der Dichtungseinsatz beim Einschieben der Dichtungswanne entlanggleitet. Dabei wird der Dichtungseinsatz, der im herausgenommenen Zustand im wesentlichen flach auf der Auffangwanne aufliegt, relativ zu derselben verschwenkt und damit aufgerichtet bis er in seine Endlage kommt.In a further advantageous embodiment, the filter device has a collection tray for insertion into a process air duct of the laundry treatment machine, on which the sealing insert is pivotably mounted. This makes it easier to insert the sealing insert, which therefore does not have to be handled separately, but can be brought into position when the drip pan is pushed in. In a particularly advantageous manner, an upwardly directed ramp edge can be formed on the floor assembly of the laundry treatment appliance in the area of the process air duct, along which the sealing insert slides when the sealing trough is pushed in. The sealing insert, which lies essentially flat on the collecting trough in the removed state, is pivoted relative to the same and is thus erected until it reaches its end position.

In einer vorteilhaften Ausführungsform ist das Filterelement als Sandwich-Filtermatte ausgebildet.In an advantageous embodiment, the filter element is designed as a sandwich filter mat.

In einer vorteilhaften Ausführungsform der Erfindung ist die Wäschebehandlungsmaschine ein Wäschetrockner. Weitere Vorteile und Merkmale der Erfindung ergeben sich aus den Unteransprüchen und aus der nachfolgenden Beschreibung einer bevorzugten Ausführungsform unter Bezugnahme auf die beigefügten Zeichnungen.In an advantageous embodiment of the invention, the laundry treatment machine is a tumble dryer. Further advantages and features of the invention emerge from the dependent claims and from the following description of a preferred embodiment with reference to the accompanying drawings.

Figur 1 zeigt in perspektivischer Darstellung eine Wäschebehandlungsmaschine gemäß einer Ausführungsform der Erfindung in Form eines Wäschetrockners 10. Der Wäschetrockner 10 weist ein Gehäuse 12 auf, in dem eine Wäschetrommel 14 gelagert ist. Eine Beschickungstür 16 verschließt eine Beschickungsöffnung, durch welche zu trocknende Wäsche (nicht dargestellt) in die Wäschetrommel 14 eingelegt werden kann. figure 1 shows a perspective view of a laundry treatment machine according to an embodiment of the invention in the form of a tumble dryer 10. The tumble dryer 10 has a housing 12 in which a laundry drum 14 is mounted. A loading door 16 closes a loading opening through which laundry (not shown) to be dried can be placed in the laundry drum 14 .

In der Frontseite des Gehäuses 12 ist eine Revisionsöffnung mit einer Klappe 18 vorgesehen (Figur 1), die in geöffnetem Zustand den Zugriff auf eine Filtereinrichtung 30 freigibt, welche weiter unten genauer beschrieben ist.In the front of the housing 12 there is an inspection opening with a flap 18 ( figure 1 ), which in the open state gives access to a filter device 30, which is described in more detail below.

In dem Wäschetrockner 10 ist ein Prozeßluftstrom 20 in einer Prozeßluftstromführung geführt, deren Elemente in Figur 2 in einem schematischen Schnitt durch den Wäschetrockner 10 dargestellt sind. Hierbei wird die in einer Heizeinrichtung 21 erwärmte Prozeßluft in an sich bekannter Weise in einem Kreislauf mit Hilfe eines Gebläses 22 durch die Wäschetrommel 14 und anschließend zu einem Wärmetauscher 24 geführt.In the tumble dryer 10, a process air flow 20 is guided in a process air flow guide, the elements of which are in figure 2 are shown in a schematic section through the tumble dryer 10. Here, the process air heated in a heating device 21 is circulated in a manner known per se with the aid of a blower 22 through the laundry drum 14 and then to a heat exchanger 24 .

Strömungsseitig vor dem Wärmetauscher 24 ist eine Filtereinrichtung 30 vorgesehen. Wie in Figur 2 dargestellt, wird die feuchte Prozeßluft durch einen Absaugkanal 26 aus der Wäschetrommel 14 über die Filtereinrichtung 30 in einen Prozeßluftkanal 28 geführt, in welchem der Wärmetauscher 24 untergebracht ist. Vorteilhaft ist der Prozeßluftkanal 28 in einer Bodengruppe 29 ausgeformt, die als Kunststoffteil ausgebildet ist und die auch weitere Baugruppen, beispielsweise das Gebläse 22 und einen Kompressor (nicht dargestellt) aufnehmen kann und das Fundament des Wäschetrockners 10 bildet.A filter device 30 is provided upstream of the heat exchanger 24 on the flow side. As in figure 2 shown, the moist process air is guided through a suction duct 26 from the laundry drum 14 via the filter device 30 into a process air duct 28 in which the heat exchanger 24 is housed. The 28 in. process air duct is advantageous formed a floor assembly 29, which is designed as a plastic part and which can also accommodate other assemblies, such as the fan 22 and a compressor (not shown) and forms the foundation of the tumble dryer 10.

Die Filtereinrichtung 30, die in den Figuren 3 und 4 detaillierter dargestellt ist, weist in der gezeigten Ausführungsform einen Dichtungseinsatz 32 und einen Filterträger 34 mit einem Filterelement 36 aus einem offenporigen Schaumstoff auf.The filter device 30 in the Figures 3 and 4 shown in more detail, in the embodiment shown has a sealing insert 32 and a filter carrier 34 with a filter element 36 made of an open-cell foam.

Der Dichtungseinsatz 32 ist schwenkbar an einer Auffangwanne 38 gelagert, welche zum Betrieb des Wäschetrockners in den Prozeßluftkanal 28 eingeschoben ist und unter den Wärmetauscher 24 ragt um die mittels einer Spüleinrichtung (nicht dargestellt) vom Wärmetauscher 24 abgespülte Flusen zu sammelnThe sealing insert 32 is pivotably mounted on a collecting tray 38, which is pushed into the process air duct 28 for the operation of the tumble dryer and protrudes under the heat exchanger 24 in order to collect the fluff rinsed off the heat exchanger 24 by means of a rinsing device (not shown).

Der Dichtungseinsatz 32 ist als im wesentlichen ebener Rahmen ausgebildet. Als Rahmen umschließt der Dichtungseinsatz 32 naturgemäß eine Durchströmöffnung 44. Die Hauptebene des Dichtungseinsatzes 32 definiert eine zum Wärmetauscher weisende Vorderseite 40 und eine vom Wärmetauscher 24 weg weisenden Rückseite 42. Bezogen auf den Dichtungseinsatz seien die Richtungen parallel zum Normalenvektor der Hauptebene als axiale Richtungen bezeichnet; Richtungen senkrecht dazu als radiale Richtungen. Im eingesetzten Zustand wird der Dichtungseinsatz 32 durch die Durchströmöffnung 44 in im wesentlichen axialer Richtung, der zum Wärmetauscher 24 hin, also von der Rückseite 42 zur Vorderseite 40 durchströmt. Zur Stabilisierung des Dichtungseinsatzes 32 ist ein Stützsteg 46 vorgesehen, der die Durchströmöffnung 44 in zwei Teile 44a und 44b teilt.The sealing insert 32 is designed as a substantially planar frame. As a frame, the sealing insert 32 naturally encloses a flow opening 44. The main plane of the sealing insert 32 defines a front side 40 pointing towards the heat exchanger and a rear side 42 pointing away from the heat exchanger 24. In relation to the sealing insert, the directions parallel to the normal vector of the main plane are referred to as axial directions; Directions perpendicular thereto as radial directions. In the inserted state, the sealing insert 32 flows through the through-flow opening 44 in a substantially axial direction toward the heat exchanger 24 , ie from the back 42 to the front 40 . To stabilize the sealing insert 32, a support web 46 is provided, which divides the through-flow opening 44 into two parts 44a and 44b.

Am Rand des Dichtungseinsatzes 32 ist eine radiale Dichtlippe 48 aus einem flexiblen Material angebracht, die im eingesetzten Zustand des Dichtungseinsatzes 32 an der Wand des Prozeßluftkanals 28 anliegt (Figur 4). In Figur 5 ist dies in einem Schnitt durch den Prozeßluftkanal 28 und den Dichtungseinsatz 32 mit der radialen Dichtlippe 48 zu sehen. Auf der Rückseite 42 ist umlaufend um die beiden Teile der Durchströmöffnung 44 eine axiale Halterippe 50 ausgebildet.A radial sealing lip 48 made of a flexible material is attached to the edge of the sealing insert 32 and rests against the wall of the process air duct 28 when the sealing insert 32 is in place ( figure 4 ). In figure 5 this can be seen in a section through the process air duct 28 and the sealing insert 32 with the radial sealing lip 48 . An axial retaining rib 50 is formed on the rear side 42 around the two parts of the through-flow opening 44 .

Der Filterträger 34 bildet, wenn er in den Wäschetrockner 10 eingesetzt ist, einen Umlenkkanal 52 mit einer Lufteintrittsöffnung 54 und einer Luftaustrittsöffnung 56, der die Prozeßluft aus dem Absaugkanal 26 in den Prozeßluftkanal 28 leitet. An der Luftaustrittsöffnung 56 ist das Filterelement 36 angebracht.When it is inserted into the tumble dryer 10, the filter support 34 forms a deflection duct 52 with an air inlet opening 54 and an air outlet opening 56, which directs the process air from the suction duct 26 into the process air duct 28. The filter element 36 is attached to the air outlet opening 56 .

In den Figuren 3 und 4 sind die Bestandteile der Filtereinrichtung separat, d.h. aus dem Wäschetrockner 10 entnommen, dargestellt. In diesem Zustand kann das Filterelement 36 durch den Benutzer gereinigt, sowie die Auffangwanne 38 entleert und gereinigt werden. Zum Betrieb des Wäschetrockners 10 ist die Auffangwanne 38 mit dem Dichtungseinsatz 32 in im wesentlichen axialer Richtung, bzw. in Richtung der Prozeßluftströmung in den Prozeßluftkanal 28 einzuschieben und danach der Filterträger 34 einzusetzen.In the Figures 3 and 4 the components of the filter device are shown separately, ie removed from the tumble dryer 10 . In this state, the filter element 36 can be cleaned by the user, and the drip pan 38 can be emptied and cleaned. To operate the tumble dryer 10, the drip tray 38 with the sealing insert 32 is to be pushed into the process air duct 28 in a substantially axial direction or in the direction of the process air flow, and then the filter carrier 34 is to be inserted.

In vorteilhafter Weise ist in der Bodengruppe 29 an den Seitenwänden des Prozeßluftkanals 28 jeweils eine Rampenkante 58 ausgebildet, die in Einschubrichtung schräg nach oben ansteigt. Beim Einschieben der Auffangwanne 38 in den Prozeßluftkanal 28 kommen die Seitenkanten des Dichtungseinsatzes 32, der zunächst flach auf der Auffangwanne 38 aufliegt, mit den Rampenkanten 58 in Kontakt und gleiten auf diesem nach oben, sodaß der Dichtungseinsatz 32 in seiner Lagerung an der Auffangwanne 38 verschwenkt und damit aufgerichtet wird. Das heißt also, daß beim Einschieben der Auffangwanne 38 in die Bodengruppe 29 automatisch der Dichtungseinsatz 32 aufgerichtet und so positioniert wird, daß danach der Filterträger34 eingesetzt werden kann.Advantageously, a ramp edge 58 is formed in the floor assembly 29 on the side walls of the process air duct 28, which rises obliquely upwards in the insertion direction. When the collecting tray 38 is pushed into the process air duct 28, the side edges of the sealing insert 32, which initially lies flat on the collecting tray 38, come into contact with the ramp edges 58 and slide upwards, so that the sealing insert 32 pivots in its mounting on the collecting tray 38 and is thus erected. This means that when the drip tray 38 is pushed into the floor assembly 29, the sealing insert 32 is automatically erected and positioned in such a way that the filter carrier 34 can then be inserted.

Sobald die Auffangwanne 38 vollständig eingeschoben ist, ist der Dichtungseinsatz 32 im Prozeßluftkanal 28 aufgenommen, sodaß er den Querschnitt desselben vollständig ausfüllt. Der Rand des Dichtungseinsatzes 32 ist so an den Querschnitt des Prozeßluftkanals 28 angepaßt, daß zwischen der Wand, genauer der Innenwand des letzteren und dem Rand ein Spalt bleibt, der ausreichend weit ist, die Dichtlippe 48 aufzunehmen, aber eng genug, daß die radiale Dichtlippe 48 von der der Innenwand des Prozeßluftkanals 28 elastisch verformt ist. Die radiale Dichtlippe 48 liegt dann unter Spannung an der Innenwand des Prozeßluftkanals 28 an. Damit ist der Spalt zwischen dem Dichtungseinsatz 32 und der Innenwand des Prozeßluftkanals 28 abgedichtet.As soon as the drip tray 38 has been fully pushed in, the sealing insert 32 is accommodated in the process air duct 28 so that it completely fills the cross section of the same. The edge of the sealing insert 32 is adapted to the cross section of the process air duct 28 that a gap remains between the wall, more precisely the inner wall of the latter and the edge, which is wide enough to accommodate the sealing lip 48, but narrow enough that the radial sealing lip 48 of which the inner wall of the process air duct 28 is elastically deformed. The radial sealing lip 48 then rests against the inner wall of the process air duct 28 under tension. The gap between the sealing insert 32 and the inner wall of the process air duct 28 is thus sealed.

Der Filterträger 34 wird hinter dem Dichtungseinsatz 32 eingesetzt, sodaß durch den im Filterträger 34 ausgebildeten Umlenkkanal 52 der Strömungsweg zwischen dem Absaugkanal 26 und dem Prozeßluftkanal 28 geschlossen ist. Der Filterträger 34 wird dann mittels Verriegelungselementen 60 in der Bodengruppe 29 fixiert und von der Klappe 18 der Revisionsöffnung verdeckt.The filter carrier 34 is inserted behind the sealing insert 32 so that the flow path between the suction channel 26 and the process air channel 28 is closed by the deflection channel 52 formed in the filter carrier 34 . The filter carrier 34 is then fixed in the floor assembly 29 by means of locking elements 60 and is covered by the flap 18 of the inspection opening.

Bei eingesetztem Filterträger 34 ist das Filterelement 36 an die Rückseite 42 des Dichtungseinsatzes 32 gepreßt und damit zuverlässig in seiner Soll-Position fixiert. Das Filterelement 36 ragt dabei radial bezüglich der Strömungsrichtung über die Durchströmöffnung 44 des Dichtungseinsatzes 32 hinaus. In Verbindung mit der Abdichtung des Dichtungseinsatzes 32 gegen die Innenwand des Prozeßluftkanals 28 ist damit sichergestellt, daß die Prozeßluft vollständig durch das Filterelement strömen muß und ein Bypaß, am Filterelement 36 vorbei, verhindert ist.When the filter carrier 34 is inserted, the filter element 36 is pressed against the rear side 42 of the sealing insert 32 and is thus reliably fixed in its desired position. The filter element 36 protrudes radially with respect to the direction of flow beyond the through-flow opening 44 of the sealing insert 32 . In conjunction with the sealing of the sealing insert 32 against the inner wall of the process air duct 28, this ensures that the process air must flow completely through the filter element and a bypass past the filter element 36 is prevented.

Zusätzlich sorgt die axiale Halterippe 50 dafür, daß das Filterelement 36 durch elastische Verformung um die Durchströmöffnung 44 herum zusätzlichen Halt erhält. Damit wird verhindert, daß sich zwischen dem Filterelement 36 und der Rückseite 42 des Dichtungseinsatzes 32 möglicherweise eine Bypaßströmung bildet, beispielsweise, weil das Material des Filterelements 36 sich von der Rückseite 42 abhebt oder der Rand des Filterelements in die Durchströmöffnung 44 rutscht.In addition, the axial retaining rib 50 ensures that the filter element 36 receives additional support through elastic deformation around the through-flow opening 44 . This prevents a bypass flow from possibly forming between the filter element 36 and the rear side 42 of the sealing insert 32, for example because the material of the filter element 36 lifts off the rear side 42 or the edge of the filter element slips into the flow opening 44.

Der Dichtungseinsatze 32 dichtet somit zum Umgebungsbauteil, dem Prozeßluftkanal 28 durch ein Dichtsystem, die radiale Dichtlippe 48 ab und bietet gleichzeitig den axialen Dichtsitz für das Schaum-Filterelement 36.
