Derartige Filteranordnungen für Wäschebehandlungsmaschinen sowie Wäschebehandlungsmaschinen sind aus dem Stand der Technik in einer Vielzahl von Ausführungsformen bereits vorbekannt. Die bekannten Filteranordnungen umfassen dabei eine Filteraufnahme, einen Filter, eine um eine Schwenkachse schwenkbare Klappe und eine Blockiervorrichtung mit einem mittels einer Feder der Blockiervorrichtung vorgespannten Blockierteil, wobei der Filter zwischen einer Aufnahmelage, in der der Filter in der Filteraufnahme aufgenommen ist, und einer Entnahmelage, in der der Filter aus der Filteraufnahme entnommen ist, hin und her überführbar ist, und wobei die Klappe zwischen einer Schließlage, in der die Klappe die Filteraufnahme derart verdeckt, dass die Klappe mit einem Rest der Wäschebehandlungsmaschine eine optische Einheit bildet und/oder eine Inbetriebnahme der Wäschebehandlungsmaschine ermöglicht, und einer Öffnungslage, in der die Klappe die Filteraufnahme freigibt, entlang eines Betätigungsweges hin und her überführbar ist, und wobei das Blockierteil der Blockiervorrichtung zwischen einer Blockierlage, in der das Blockierteil die Überführung der Klappe in deren Schließlage verhindert, und einer Freigabelage, in der das Blockierteil die Überführung der Klappe in deren Schließlage ermöglicht, hin und her überführbar ist, nämlich derart, dass die Feder das Blockierteil in Richtung von dessen Blockierlage vorspannt und das Blockierteil mittels des Filters gegen eine Federkraft der Feder in Richtung von dessen Freigabelage überführbar und in der Freigabelage halterbar ist. EP 2 664 706 A1 offenbart eine Filteranordnung für eine Wäschebehandlungsmaschine gemäß dem Oberbegriff des unabhängigen Anspruchs 1.Such filter arrangements for laundry treatment machines and laundry treatment machines are already known from the prior art in a variety of embodiments. The known filter arrangements include a filter receptacle, a filter, a flap that can be pivoted about a pivot axis and a blocking device with a blocking part biased by a spring of the blocking device, the filter being between a receiving position in which the filter is received in the filter receptacle and a removal position , in which the filter is removed from the filter receptacle, can be moved back and forth, and the flap can be moved back and forth between a closed position in which the flap covers the filter receptacle in such a way that the flap forms an optical unit with the rest of the laundry treatment machine and / or a Commissioning of the laundry treatment machine enables, and an open position in which the flap releases the filter receptacle, can be moved back and forth along an actuation path, and wherein the blocking part of the blocking device between a blocking position in which the blocking part prevents the flap from being transferred into its closed position, and a release position in which the blocking part enables the flap to be transferred into its closed position, can be moved back and forth, namely in such a way that the spring biases the blocking part in the direction of its blocking position and the blocking part by means of the filter against a spring force of the spring in the direction of whose release position can be transferred and held in the release position. EP 2 664 706 A1 discloses a filter arrangement for a laundry treatment machine according to the preamble of independent claim 1.

Der Erfindung stellt sich somit das Problem, eine verbesserte Filteranordnung für eine Wäschebehandlungsmaschine und eine verbesserte Wäschebehandlungsmaschine anzugeben.The invention therefore faces the problem of specifying an improved filter arrangement for a laundry treatment machine and an improved laundry treatment machine.

Erfindungsgemäß wird dieses Problem durch eine Filteranordnung für eine Wäschebehandlungsmaschine mit den Merkmalen des Patentanspruchs 1 gelöst, die dadurch gekennzeichnet ist, dass das Blockierteil als ein in einer quer zum Betätigungsweg der Klappe verlaufenden Schieberführung der Filteranordnung beweglich gelagerter Schieber ausgebildet ist, wobei die Schieberführung einen zu der Blockierlage korrespondierenden ersten Endanschlag für den Schieber und einen zu der Freigabelage korrespondierenden zweiten Endanschlag für den Schieber aufweist. Ferner wird dieses Problem durch eine Wäschebehandlungsmaschine mit den Merkmalen des Patentanspruchs 9 gelöst. Die erfindungsgemäße Wäschebehandlungsmaschine kann dabei als ein Wäschetrockner für Textilien oder ein Waschtrockner für Textilien ausgebildet sein. Ferner kann die erfindungsgemäße Wäschebehandlungsmaschine als ein Haushaltsgerät oder ein gewerbliches Gerät, also ein Gerät für den professionellen Einsatz, ausgebildet sein. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung ergeben sich aus den nachfolgenden Unteransprüchen.According to the invention, this problem is solved by a filter arrangement for a laundry treatment machine with the features of patent claim 1, which is characterized in that the blocking part is designed as a slide which is movably mounted in a slide guide of the filter arrangement which runs transversely to the actuation path of the flap, the slide guide having one has a first end stop for the slide that corresponds to the blocking position and a second end stop for the slide that corresponds to the release position. Furthermore, this problem is solved by a laundry treatment machine with the features of patent claim 9. The Laundry treatment machine according to the invention can be designed as a tumble dryer for textiles or a washer-dryer for textiles. Furthermore, the laundry treatment machine according to the invention can be designed as a household appliance or a commercial device, i.e. a device for professional use. Advantageous refinements and further developments of the invention result from the following subclaims.

Der mit der Erfindung erreichbare Vorteil besteht insbesondere darin, dass eine Filteranordnung für eine Wäschebehandlungsmaschine und eine Wäschebehandlungsmaschine verbessert sind. Aufgrund der erfindungsgemäßen Ausbildung der Filteranordnung für eine Wäschebehandlungsmaschine und der Wäschebehandlungsmaschine ist ermöglicht, dass die Klappe nicht in ungewünschter Weise durch die Blockiervorrichtung mit dem durch die Feder vorgespannten Blockierteil vorgespannt ist. Im Unterschied dazu ist es bei den bekannten Filteranordnungen und Wäschebehandlungsmaschinen nämlich so, dass die Klappe aufgrund des mittels der Feder vorgespannten Blockierteils ständig mechanisch belastet ist. Hier schafft die Erfindung Abhilfe. Entsprechend sind die erfindungsgemäße Filteranordnung und die erfindungsgemäße Wäschebehandlungsmaschine einfacher und damit kostengünstiger im Aufbau und langlebiger.The advantage that can be achieved with the invention is, in particular, that a filter arrangement for a laundry treatment machine and a laundry treatment machine are improved. Due to the inventive design of the filter arrangement for a laundry treatment machine and the laundry treatment machine, it is possible that the flap is not biased in an undesirable manner by the blocking device with the blocking part preloaded by the spring. In contrast to this, in the known filter arrangements and laundry treatment machines, the flap is constantly mechanically loaded due to the blocking part which is preloaded by the spring. The invention provides a remedy here. Accordingly, the filter arrangement according to the invention and the laundry treatment machine according to the invention are simpler and therefore cheaper to construct and more durable.

Grundsätzlich ist die erfindungsgemäße Filteranordnung für eine Wäschebehandlungsmaschine nach Art, Funktionsweise, Material, Dimensionierung und Anordnung in weiten geeigneten Grenzen frei wählbar.In principle, the filter arrangement according to the invention for a laundry treatment machine can be freely selected within wide suitable limits in terms of type, functionality, material, dimensions and arrangement.

Eine vorteilhafte Weiterbildung der erfindungsgemäßen Filteranordnung sieht vor, dass der Filter einen Filtergriff aufweist, wobei die Blockiervorrichtung und der Filter derart aufeinander abgestimmt ausgebildet sind, dass der Schieber mittels des Filtergriffs von dessen Blockierlage in dessen Freigabelage überführbar und in der Freigabelage halterbar ist. Auf diese Weise ist der Filter zum einen einfacher handhabbar. Zum anderen ist es dadurch möglich, die Überführung des Schiebers von dessen Blockierlage in dessen Freigabelage nicht lediglich von der Überführung des Filters von dessen Entnahmelage in dessen Aufnahmelage, sondern zusätzlich von der relativen Lage des Filtergriffs abhängig zu gestalten. Entsprechend ist es beispielsweise möglich, die Überführung des Schiebers von dessen Blockierlage in dessen Freigabelage abhängig von einer ordnungsgemäßen Lage des Filtergriffs relativ zu der Filteraufnahme und/oder der Klappe zu ermöglichen oder zu verhindern.An advantageous development of the filter arrangement according to the invention provides that the filter has a filter handle, the blocking device and the filter being designed to be coordinated with one another in such a way that the slide can be moved from its blocking position to its release position by means of the filter handle and can be held in the release position. In this way, the filter is easier to handle. On the other hand, this makes it possible to make the transfer of the slider from its blocking position to its release position dependent not only on the transfer of the filter from its removal position to its receiving position, but also on the relative position of the filter handle. Accordingly, it is possible, for example, to enable or prevent the transfer of the slide from its blocking position to its release position depending on a proper position of the filter handle relative to the filter holder and/or the flap.

Eine vorteilhafte Weiterbildung der vorgenannten Ausführungsform der erfindungsgemäßen Filteranordnung sieht vor, dass der Filter und die Filteraufnahme derart aufeinander abgestimmt ausgebildet sind, dass der Filtergriff zwischen einer Verriegelungslage, in der der Filtergriff mit der Filteraufnahme verriegelt ist, und einer Entriegelungslage, in der der Filtergriff mit der Filteraufnahme nicht verriegelt ist, hin und her überführbar ist, wobei der Schieber mittels des Filtergriffs bei dessen Überführung in die Verriegelungslage gleichzeitig in dessen Freigabelage überführbar und in der Freigabelage halterbar ist, und wobei der Schieber mittels der Feder bei der Überführung des Filtergriffs in dessen Entriegelungslage gleichzeitig in die Blockierlage des Schiebers überführbar ist. Hierdurch ist zum einen gewährleistet, dass eine Überführung des Schiebers von dessen Blockierlage in dessen Freigabelage lediglich dann möglich ist, wenn sich der Filter ordnungsgemäß in dessen Aufnahmelage befindet und mittels des Filtergriffs verriegelt ist. Zum anderen Bedarf es zur Überführung des Schiebers von dessen Freigabelage in dessen Blockierlage lediglich der Überführung des Filtergriffs von dessen Verriegelungslage in dessen Entriegelungslage.An advantageous development of the aforementioned embodiment of the filter arrangement according to the invention provides that the filter and the filter holder are designed to be coordinated with one another in such a way that the filter handle is positioned between a locking position in which the Filter handle is locked with the filter receptacle, and an unlocking position in which the filter handle is not locked with the filter receptacle, can be moved back and forth, the slide being able to be transferred to its release position and held in the release position by means of the filter handle when it is transferred to the locking position is, and wherein the slide can be moved into the blocking position of the slide at the same time by means of the spring when the filter handle is transferred to its unlocking position. This ensures, on the one hand, that a transfer of the slide from its blocking position to its release position is only possible if the filter is properly in its receiving position and is locked by means of the filter handle. On the other hand, all that is required to transfer the slider from its release position to its blocking position is to transfer the filter handle from its locking position to its unlocking position.

Eine vorteilhafte Weiterbildung der erfindungsgemäßen Filteranordnung nach Anspruch 3 sieht vor, dass die Filteraufnahme mindestens eine Kreisbogenführung und der Filtergriff mindestens einen zu der Kreisbogenführung korrespondierenden Kreisbogenvorsprung aufweist, wobei der Kreisbogenvorsprung und die Kreisbogenführung derart aufeinander abgestimmt ausgebildet sind, dass der Filtergriff mittels des Kreisbogenvorsprungs und der Kreisbogenführung bei dessen Überführung in die Verriegelungslage in der Filteraufnahme verriegelbar und bei dessen Überführung in die Entriegelungslage entriegelbar ist. Auf diese Weise ist die Mechanik für den Filtergriff zur Überführung des Filtergriffs von dessen Entriegelungslage in dessen Verriegelungslage und umgekehrt auf konstruktiv und fertigungstechnisch einfache sowie platzsparende Art realisiert.An advantageous development of the filter arrangement according to the invention according to claim 3 provides that the filter holder has at least one circular arc guide and the filter handle has at least one circular arc projection corresponding to the circular arc guide, the circular arc projection and the circular arc guide being designed to be coordinated with one another in such a way that the filter handle is coordinated with one another by means of the circular arc projection and the Circular arc guide can be locked in the filter holder when it is transferred to the locking position and can be unlocked when it is transferred to the unlocking position. In this way, the mechanics for the filter handle for transferring the filter handle from its unlocking position to its locking position and vice versa are implemented in a simple, space-saving manner in terms of construction and production technology.

Eine vorteilhafte Weiterbildung der letztgenannten Ausführungsform der erfindungsgemäßen Filteranordnung sieht vor, dass mindestens eine der mindestens einen Kreisbogenführung relativ zu der Schieberführung derart angeordnet ist, dass der in der Schieberführung geführte Schieber mittels eines Betätigungsvorsprungs des Schiebers und des zu der vorgenannten Kreisbogenführung korrespondierenden Kreisbogenvorsprungs des Filtergriffs zwischen der Blockierlage und der Freigabelage hin und her überführbar ist. Hierdurch ist die mechanische Kopplung des in der Kreisbogenführung der Filteraufnahme geführten Filtergriffs mit dem in der Schieberführung geführten Schieber der Blockiervorrichtung auf konstruktiv besonders einfache Weise ermöglicht.An advantageous development of the last-mentioned embodiment of the filter arrangement according to the invention provides that at least one of the at least one circular arc guide is arranged relative to the slide guide in such a way that the slide guided in the slide guide is between by means of an actuating projection of the slide and the circular arc projection of the filter handle corresponding to the aforementioned circular arc guide the blocking position and the release position can be transferred back and forth. This enables the mechanical coupling of the filter handle, which is guided in the circular arc guide of the filter holder, to the slide of the blocking device, which is guided in the slide guide, in a particularly simple manner.

Eine weitere vorteilhafte Weiterbildung der erfindungsgemäßen Filteranordnung sieht vor, dass die Feder als ein separates Teil ausgebildet ist, bevorzugt, dass die Feder als ein Metallteil ausgebildet ist. Auf diese Weise ist es beispielsweise möglich, die Feder unabhängig von den konstruktiven und fertigungstechnischen Bedingungen für den Schieber auszuwählen oder zu gestalten. Darüber hinaus sind Metallfedern, beispielsweise Blechfedern oder Drahtfedern, besonders robust und in einer Vielzahl von voneinander verschiedenen Ausführungsformen im Handel erhältlich. Im Unterschied dazu ist es jedoch grundsätzlich auch denkbar, dass die Feder als ein integraler Bestandteil des Schiebers, beispielsweise eines Schiebers aus einem Kunststoff, ausgebildet ist.A further advantageous development of the filter arrangement according to the invention provides that the spring is designed as a separate part, preferably that the spring is designed as a metal part. In this way, it is possible, for example, to select or design the spring independently of the design and manufacturing conditions for the slide. In addition, metal springs, such as sheet metal springs or wire springs, are particularly robust and come in a variety of sizes Various embodiments commercially available. In contrast to this, however, it is also fundamentally conceivable for the spring to be designed as an integral part of the slide, for example a slide made of plastic.

Eine andere vorteilhafte Weiterbildung der erfindungsgemäßen Filteranordnung sieht vor, dass der Schieber und die Schieberführung zueinander korrespondierende Rastmittel aufweisen, wobei der Schieber mittels dieser Rastmittel an der Filteraufnahme beweglich angeordnet ist. Hierdurch ist die bewegliche Lagerung des Schiebers an der Schieberführung auf konstruktiv besonders einfache und robuste Weise realisiert.Another advantageous development of the filter arrangement according to the invention provides that the slide and the slide guide have mutually corresponding locking means, the slide being movably arranged on the filter holder by means of these locking means. As a result, the movable mounting of the slider on the slider guide is realized in a particularly simple and robust manner.

Eine weitere vorteilhafte Weiterbildung der erfindungsgemäßen Filteranordnung sieht vor, dass die Klappe einen Klappenvorsprung aufweist, wobei der Klappenvorsprung und die Blockiervorrichtung derart aufeinander abgestimmt ausgebildet und angeordnet sind, dass der Schieber in dessen Blockierlage lediglich mit dem Klappenvorsprung in Eingriff ist und in dessen Freigabelage mit dem Klappenvorsprung nicht in Eingriff ist. Auf diese Weise ist die mechanische Wirkverbindung zwischen der Blockiervorrichtung auf der einen Seite und der Klappe auf der anderen Seite konstruktiv und fertigungstechnisch einfach umgesetzt. Ferner ist dadurch die ästhetische Gestaltung der Klappe in deren Schließlage, beispielsweise als gestalterische Einheit mit einem Korpus der Wäschebehandlungsmaschine, nicht beeinträchtigt.A further advantageous development of the filter arrangement according to the invention provides that the flap has a flap projection, the flap projection and the blocking device being designed and arranged in such a way that they are coordinated with one another in such a way that the slide in its blocking position is only in engagement with the flap projection and in its release position with the Flap projection is not engaged. In this way, the mechanical active connection between the blocking device on one side and the flap on the other side is implemented in a simple manner in terms of construction and production technology. Furthermore, this does not affect the aesthetic design of the flap in its closed position, for example as a design unit with a body of the laundry treatment machine.

Eine vorteilhafte Weiterbildung der erfindungsgemäßen Wäschebehandlungsmaschine sieht vor, dass die Filteranordnung, bevorzugt die Filteraufnahme, zumindest teilweise als ein Teil des Gehäuses ausgebildet ist. Hierdurch ist die Bauteilanzahl reduziert und der konstruktive Aufbau der Wäschebehandlungsmaschine vereinfacht. Dies gilt insbesondere für die bevorzugte Ausführungsform dieser Weiterbildung.An advantageous development of the laundry treatment machine according to the invention provides that the filter arrangement, preferably the filter holder, is at least partially designed as a part of the housing. This reduces the number of components and simplifies the structural design of the laundry treatment machine. This applies in particular to the preferred embodiment of this development.

In den Fig. 1 bis 7 ist ein Ausführungsbeispiel der erfindungsgemäßen Wäschebehandlungsmaschine mit der erfindungsgemäßen Filteranordnung rein exemplarisch dargestellt.In the Fig. 1 to 7 an embodiment of the laundry treatment machine according to the invention with the filter arrangement according to the invention is shown purely as an example.

Die Wäschebehandlungsmaschine 1 ist als ein Haushaltswäschetrockner für Textilien ausgebildet und weist ein Gehäuse 2 und eine Filteranordnung 3 auf. Die Filteranordnung 3 umfasst eine Filteraufnahme 4, einen Filter 6, eine um eine Schwenkachse 8 schwenkbare Klappe 10 und eine Blockiervorrichtung 12 mit einem mittels einer Feder 14 der Blockiervorrichtung 12 vorgespannten Blockierteil 16, wobei der Filter 6 zwischen einer in den Fig. 4 und 5 dargestellten Aufnahmelage, in der der Filter 6 in der Filteraufnahme 4 aufgenommen ist, und einer in der Fig. 1 dargestellten Entnahmelage, in der der Filter 6 aus der Filteraufnahme 4 entnommen ist, hin und her überführbar ist, und wobei die Klappe 10 zwischen einer in der Fig. 7 dargestellten Schließlage, in der die Klappe 10 die Filteraufnahme 4 derart verdeckt, dass die Klappe 10 mit einem Rest der Wäschebehandlungsmaschine 1 eine optische Einheit bildet und eine Inbetriebnahme der Wäschebehandlungsmaschine 1 ermöglicht, und einer in der Fig. 1 dargestellten Öffnungslage, in der die Klappe 10 die Filteraufnahme 4 freigibt, entlang eines Betätigungsweges hin und her überführbar ist, und wobei das Blockierteil 16 der Blockiervorrichtung 12 zwischen einer in den Fig. 1, 3 und 4 dargestellten Blockierlage, in der das Blockierteil 16 die Überführung der Klappe 10 in deren Schließlage verhindert, und einer in der Fig. 5 dargestellten Freigabelage, in der das Blockierteil 16 die Überführung der Klappe 10 in deren Schließlage ermöglicht, hin und her überführbar ist, nämlich derart, dass die Feder 14 das Blockierteil 16 in Richtung von dessen Blockierlage vorspannt und das Blockierteil 16 mittels des Filters 6 gegen eine Federkraft der Feder 14 in Richtung von dessen Freigabelage überführbar und in der Freigabelage halterbar ist.The laundry treatment machine 1 is designed as a household tumble dryer for textiles and has a housing 2 and a filter arrangement 3. The filter arrangement 3 comprises a filter receptacle 4, a filter 6, a flap 10 which can be pivoted about a pivot axis 8 and a blocking device 12 with a blocking part 16 prestressed by means of a spring 14 of the blocking device 12, the filter 6 being between one in the Fig. 4 and 5 illustrated recording position, in which the filter 6 is accommodated in the filter holder 4, and one in the Fig. 1 illustrated removal position, in which the filter 6 is removed from the filter holder 4, can be moved back and forth, and the flap 10 is between one in the Fig. 7 shown closed position, in which the flap 10 covers the filter holder 4 in such a way that the flap 10 forms an optical unit with the rest of the laundry treatment machine 1 and enables the laundry treatment machine 1 to be started up, and one in the Fig. 1 Opening position shown, in which the flap 10 releases the filter receptacle 4, can be moved back and forth along an actuation path, and the blocking part 16 of the blocking device 12 is between one in the Fig. 1 , 3 and 4 shown blocking position, in which the blocking part 16 prevents the flap 10 from being transferred to its closed position, and one in the Fig. 5 shown release position, in which the blocking part 16 enables the flap 10 to be transferred into its closed position, can be moved back and forth, namely in such a way that the spring 14 biases the blocking part 16 in the direction of its blocking position and the blocking part 16 against one by means of the filter 6 Spring force of the spring 14 can be transferred in the direction of its release position and can be held in the release position.

Das Blockierteil 16 ist erfindungsgemäß als ein in einer quer zum Betätigungsweg der Klappe 10 verlaufenden Schieberführung 18 der Filteranordnung 3 beweglich gelagerter Schieber ausgebildet, wobei die Schieberführung 18 einen zu der Blockierlage korrespondierenden ersten Endanschlag für den Schieber 16 und einen zu der Freigabelage korrespondierenden zweiten Endanschlag für den Schieber 16 aufweist. Der Schieber 16 ist als ein Kunststoffspritzgussteil ausgebildet. Die Feder 14 ist bei dem vorliegenden Ausführungsbeispiel als eine separate Metallfeder ausgebildet und auf dem Fachmann bekannte Weise mit dem Schieber 16 kraftübertragend verbunden. Der Schieber 16 und die Schieberführung 18 weisen zueinander korrespondierende Rastmittel auf, wobei der Schieber 16 mittels dieser Rastmittel an der Filteraufnahme 4 beweglich angeordnet ist. Siehe hierzu insbesondere die Fig. 2b, in der lediglich die als Rastnasen ausgebildeten Rastmittel 19 des Schiebers 16 dargestellt sind. Diese Rastmittel 19 greifen auf dem Fachmann bekannte Weise in die dazu korrespondierend ausgebildeten, nicht dargestellten Rastmittel der Schieberführung 18 ein, so dass der Schieber 16 in der Schieberführung 18 derart beweglich gehalten ist, dass der Schieber 16 in der jeweiligen Bildebene der Fig. 1 bis 5 von oben nach unten und von unten nach oben bewegbar ist. Die Klappe 10 weist einen Klappenvorsprung 11 auf, wobei der Klappenvorsprung 11 und die Blockiervorrichtung 12 derart aufeinander abgestimmt ausgebildet und angeordnet sind, dass der Schieber 16 in dessen Blockierlage lediglich mit dem Klappenvorsprung 11 in Eingriff ist und in dessen Freigabelage mit dem Klappenvorsprung 11 nicht in Eingriff ist. Siehe hierzu insbesondere die Fig. 6 und 7.According to the invention, the blocking part 16 is designed as a slide movably mounted in a slide guide 18 of the filter arrangement 3 that runs transversely to the actuation path of the flap 10, the slide guide 18 having a first end stop for the slide 16 that corresponds to the blocking position and one that corresponds to the release position second end stop for the slide 16. The slide 16 is designed as a plastic injection molded part. In the present exemplary embodiment, the spring 14 is designed as a separate metal spring and is connected to the slide 16 in a force-transmitting manner in a manner known to those skilled in the art. The slide 16 and the slide guide 18 have mutually corresponding locking means, the slide 16 being movably arranged on the filter holder 4 by means of these locking means. See in particular the Fig. 2b , in which only the locking means 19 of the slide 16, which are designed as locking lugs, are shown. These locking means 19 engage in a manner known to those skilled in the art in the correspondingly designed, not shown, locking means of the slide guide 18, so that the slide 16 is held movably in the slide guide 18 in such a way that the slide 16 is in the respective image plane of the Fig. 1 to 5 can be moved from top to bottom and from bottom to top. The flap 10 has a flap projection 11, the flap projection 11 and the blocking device 12 being designed and arranged in such a way that they are coordinated with one another in such a way that the slide 16 is only in engagement with the flap projection 11 in its blocking position and is not in engagement with the flap projection 11 in its release position intervention is. See in particular the Figs. 6 and 7 .

Bei dem vorliegenden Ausführungsbeispiel ist die Filteranordnung 3, nämlich die Filteraufnahme 4, zumindest teilweise als ein Teil des Gehäuses 2 ausgebildet.In the present exemplary embodiment, the filter arrangement 3, namely the filter holder 4, is at least partially designed as a part of the housing 2.

Der als Tiefenfilter ausgebildete und in dessen Aufnahmelage strömungstechnisch vor einem nicht dargestellten Wärmetauscher der Wäschebehandlungsmaschine 1 angeordnete Filter 6 weist einen Filtergriff 20 auf, wobei die Blockiervorrichtung 12 und der Filter 6 derart aufeinander abgestimmt ausgebildet sind, dass der Schieber 16 mittels des Filtergriffs 20 von dessen Blockierlage in dessen Freigabelage überführbar und in der Freigabelage halterbar ist.The filter 6, which is designed as a depth filter and is arranged in its receiving position in front of a heat exchanger (not shown) of the laundry treatment machine 1, has a filter handle 20, the blocking device 12 and the filter 6 being designed to be coordinated with one another in such a way that the slide 16 is separated from it by means of the filter handle 20 Blocking position can be transferred to its release position and can be held in the release position.

Ferner sind der Filter 6 und die Filteraufnahme 4 derart aufeinander abgestimmt ausgebildet, dass der Filtergriff 20 zwischen einer in der Fig. 5 dargestellten Verriegelungslage, in der der Filtergriff 20 mit der Filteraufnahme 4 verriegelt ist, und einer in der Fig. 4 dargestellten Entriegelungslage, in der der Filtergriff 20 mit der Filteraufnahme 4 nicht verriegelt ist, hin und her überführbar ist, wobei der Schieber 16 mittels des Filtergriffs 20 bei dessen Überführung in die Verriegelungslage gleichzeitig in dessen Freigabelage überführbar und in der Freigabelage halterbar ist, und wobei der Schieber 16 mittels der Feder 14 bei der Überführung des Filtergriffs 20 in dessen Entriegelungslage gleichzeitig in die Blockierlage des Schiebers 16 überführbar ist.Furthermore, the filter 6 and the filter holder 4 are designed to be coordinated with one another in such a way that the filter handle 20 is between one in the Fig. 5 locking position shown, in which the filter handle 20 is locked with the filter holder 4, and one in the Fig. 4 shown unlocking position, in which the filter handle 20 is not locked with the filter holder 4, can be moved back and forth, the slide 16 being able to be moved into its release position and held in the release position by means of the filter handle 20 when it is transferred to the locking position, and where the slide 16 can be simultaneously transferred into the blocking position of the slide 16 by means of the spring 14 when the filter handle 20 is transferred into its unlocking position.

Hierfür weist die Filteraufnahme 4 zwei Kreisbogenführungen 22 und der Filtergriff 20 zwei jeweils zu einer der zwei Kreisbogenführungen 22 korrespondierende Kreisbogenvorsprünge 24 auf, wobei die Kreisbogenvorsprünge 24 und die dazu korrespondierenden Kreisbogenführungen 22 derart aufeinander abgestimmt ausgebildet sind, dass der Filtergriff 20 mittels der Kreisbogenvorsprünge 24 und der Kreisbogenführungen 22 bei dessen Überführung in die Verriegelungslage in der Filteraufnahme 4 verriegelbar und bei dessen Überführung in die Entriegelungslage entriegelbar ist.For this purpose, the filter holder 4 has two circular arc guides 22 and the filter handle 20 has two circular arc projections 24, each corresponding to one of the two circular arc guides 22, the circular arc projections 24 and the corresponding ones Circular arc guides 22 are designed to be coordinated with one another in such a way that the filter handle 20 can be locked in the filter holder 4 by means of the circular arc projections 24 and the circular arc guides 22 when it is transferred to the locking position and can be unlocked when it is transferred to the unlocking position.

Einer der zwei Kreisbogenführungen 22 ist relativ zu der Schieberführung 18 derart angeordnet, dass der in der Schieberführung 18 geführte Schieber 16 mittels eines Betätigungsvorsprungs 26 des Schiebers 16 und des zu der vorgenannten Kreisbogenführung 22 korrespondierenden Kreisbogenvorsprungs 24 des Filtergriffs 20 zwischen der Blockierlage und der Freigabelage hin und her überführbar ist.One of the two circular arc guides 22 is arranged relative to the slide guide 18 in such a way that the slide 16 guided in the slide guide 18 is moved between the blocking position and the release position by means of an actuating projection 26 of the slide 16 and the circular arc projection 24 of the filter handle 20 corresponding to the aforementioned circular arc guide 22 and can be transferred here.

Nachfolgend wird die Funktionsweise der erfindungsgemäßen Filteranordnung und der erfindungsgemäßen Wäschebehandlungsmaschine gemäß dem vorliegenden Ausführungsbeispiel anhand der Fig. 1 bis 7 näher erläutert.The functionality of the filter arrangement according to the invention and the laundry treatment machine according to the invention according to the present exemplary embodiment is described below using the Fig. 1 to 7 explained in more detail.

Zunächst befindet sich die Wäschebehandlungsmaschine 1 in dem in der Fig. 7 gezeigten Zustand, in dem sich die Klappe 10 in deren Schließlage befindet. In der Schließlage der Klappe 10 bildet die Klappe 10 mit einem Rest der Wäschebehandlungsmaschine 1 zum einen eine optische Einheit und ermöglicht zum anderen eine Inbetriebnahme der Wäschebehandlungsmaschine 1. Beispielsweise kann die vorgenannte Inbetriebnahmemöglichkeit mittels eines in der Schließlage der Klappe 10 betätigbaren Schalter oder dergleichen auf schaltungstechnisch einfache Weise realisiert sein.First of all, the laundry treatment machine 1 is located in the Fig. 7 shown state in which the flap 10 is in its closed position. In the closed position of the flap 10, the flap 10 forms an optical unit with the rest of the laundry treatment machine 1 and, on the other hand, enables the laundry treatment machine 1 to be put into operation. For example, the aforementioned start-up option can be switched on by means of a switch or the like that can be actuated in the closed position of the flap 10 be realized in a simple manner.

Der Filter 6 befindet sich in dessen Aufnahmelage, der Filtergriff 20 befindet sich in dessen Verriegelungslage und der Schieber 16 befindet sich in dessen Freigabelage. Wie aus den obigen und den nachfolgenden Ausführungen erkennbar ist, wird die Klappe 10 in deren Schließlage nicht in ungewünschter Weise durch die Federkraft der Feder 14 mechanisch belastet. Dies deshalb, weil die Feder 14, die den Schieber 16 vorspannt, aufgrund der Anordnung der Schieberführung 18 quer zu dem Betätigungsweg der Klappe 10 wirkt.The filter 6 is in its receiving position, the filter handle 20 is in its locking position and the slide 16 is in its release position. As can be seen from the above and the following statements, the flap 10 is not mechanically loaded in an undesirable manner by the spring force of the spring 14 in its closed position. This is because the spring 14, which biases the slide 16, acts transversely to the actuation path of the flap 10 due to the arrangement of the slide guide 18.

Zwecks Reinigung des Filters 6 öffnet ein nicht dargestellter Benutzer die Klappe 10, in dem er diese von deren Schließlage in deren in den Fig. 1, 4 und 5 gezeigte Öffnungslage überführt.In order to clean the filter 6, a user (not shown) opens the flap 10 by moving it from its closed position to its closed position Fig. 1 , 4 and 5 shown opening position transferred.

Der Benutzer kann nun den Filtergriff 20 von dessen in der Fig. 5 dargestellten Verriegelungslage in dessen in den Fig. 1 und 4 dargestellte Entriegelungslage überführen und den Filter 6 auf dem Fachmann bekannte Weise mittels des Filtergriffs 20 aus der Filteraufnahme 4 entnehmen. Der Filter 6 wird also von dessen in den Fig. 4 und 5 dargestellten Aufnahmelage in dessen in der Fig. 1 dargestellte Entnahmelage überführt. Gleichzeitig mit der Überführung des Filtergriffs 20 von dessen Verriegelungslage in dessen Entriegelungslage wird der Schieber 16 mittels der Federkraft der Feder 14 entlang der Schieberführung 18 von dessen Freigabelage in dessen Blockierlage überführt. Der Schieber 16 befindet sich also in der in den Fig. 1, 3 und 4 gezeigten Lage, also am oberen Endanschlag der Schieberführung 18.The user can now use the filter handle 20 in the Fig. 5 shown locking position in the Fig. 1 and 4 Transfer to the unlocking position shown and remove the filter 6 from the filter holder 4 in a manner known to those skilled in the art using the filter handle 20. The filter 6 is therefore in the Fig. 4 and 5 shown recording position in its in the Fig. 1 transferred to the removal position shown. Simultaneously with the transfer of the filter handle 20 from its locking position to its Unlocking position, the slide 16 is transferred from its release position to its blocking position along the slide guide 18 by means of the spring force of the spring 14. The slider 16 is therefore located in the Fig. 1 , 3 and 4 position shown, i.e. at the upper end stop of the slide guide 18.

Zwecks Reinigung oder Austausch des Filters 6 kann es beispielsweise vorgesehen sein, dass der Filtergriff 20 wiederverwendbar ist und lediglich ein Rest des Filters 6 ausgetauscht wird. Entsprechend wäre der Filtergriff 20 lösbar an dem Rest des Filters 6 befestigt. Jedoch sind auch Ausführungsformen denkbar, bei denen der Filter 6 eine unlösbare Einheit bildet; bei denen also der Filtergriff von dem Rest des Filters nicht lösbar ist. Da sich der Schieber 16, wie oben erläutert, in dessen Blockierlage befindet, würde die Klappe 10 mittels des Klappenvorsprungs 11 und des Schiebers 16 daran gehindert, in deren in der Fig. 7 dargestellte Schließlage überführt zu werden. Stattdessen würde die Klappe 10 mit dem Klappenvorsprung 11 gegen den Schieber 16 stoßen, so dass sich die Klappe 10 lediglich bis in eine in der Fig. 6 gezeigte Zwischenlage überführen ließe.For the purpose of cleaning or replacing the filter 6, it can be provided, for example, that the filter handle 20 is reusable and only a remainder of the filter 6 is replaced. Accordingly, the filter handle 20 would be detachably attached to the rest of the filter 6. However, embodiments are also conceivable in which the filter 6 forms an inseparable unit; where the filter handle cannot be detached from the rest of the filter. Since the slide 16, as explained above, is in its blocking position, the flap 10 would be prevented from being in its position by means of the flap projection 11 and the slide 16 Fig. 7 to be transferred to the closed position shown. Instead, the flap 10 would abut with the flap projection 11 against the slide 16, so that the flap 10 only extends into one Fig. 6 shown intermediate layer could be transferred.

Der Benutzer würde also mittels der Klappe 10 leicht erkennen können, dass der Filter 6 nicht in die Filteraufnahme 4 eingesetzt und mittels des Filtergriffs 20 verriegelt worden ist. Eine zusätzliche Elektronik oder dergleichen für diese Erkennung ist erfindungsgemäß nicht erforderlich. Auch in der Blockierlage des Schiebers 16 wird die Klappe 10 aufgrund der Federkraft der den Schieber 16 in Richtung von dessen Blockierlage vorspannenden Feder 14 mechanisch nicht belastet. Da sich die Klappe 10 nicht in deren Schließlage befindet, ist der oben beispielhaft genannte, nicht dargestellte Schalter zur Inbetriebnahme der Wäschebehandlungsmaschine 1 mittels der Klappe 10 nicht betätigt, so dass bei in der vorgenannten Zwischenlage befindlicher Klappe 10 eine Inbetriebnahme der Wäschebehandlungsmaschine 1, also ein Start der Wäschebehandlungsmaschine 1 zur Trocknung von zu trocknender Textilien, nicht möglich.The user would therefore be able to easily see by means of the flap 10 that the filter 6 has not been inserted into the filter holder 4 and has been locked by means of the filter handle 20. According to the invention, additional electronics or the like are not required for this detection. Even in the blocking position of the slide 16, the flap 10 is not mechanically loaded due to the spring force of the spring 14 biasing the slide 16 in the direction of its blocking position. Since the flap 10 is not in its closed position, the above-mentioned switch (not shown) for starting up the laundry treatment machine 1 by means of the flap 10 is not actuated, so that when the flap 10 is in the aforementioned intermediate position, the laundry treatment machine 1 is started up, i.e. a Starting the laundry treatment machine 1 for drying textiles to be dried is not possible.

Nachdem der Filter 6 von dem Benutzer gereinigt oder ausgetauscht worden ist, setzt der Benutzer den Filter 6 mittels des Filtergriffs 20 wieder in die Filteraufnahme 4 ein. Der Filter 6 wird also wieder von dessen Entnahmelage in dessen Aufnahmelage überführt. Der Filter 6 ist nun wieder in die Filteraufnahme 4 eingesetzt; siehe hierzu die Fig. 4.After the filter 6 has been cleaned or replaced by the user, the user places the filter 6 back into the filter holder 4 using the filter handle 20. The filter 6 is therefore transferred again from its removal position to its receiving position. The filter 6 is now inserted back into the filter holder 4; see the Fig. 4 .

Um den Filter 6 in dessen Aufnahmelage in der Filteraufnahme 4 ordnungsgemäß zu sichern, überführt der Benutzer den Filtergriff 20 des Filters 6 von dessen in der Fig. 4 dargestellten Entriegelungslage in dessen in der Fig. 5 dargestellte Verriegelungslage. Hierzu dreht der Benutzer den Filtergriff 20 bei dem vorliegenden Ausführungsbeispiel um eine in der jeweiligen Bildebene der Fig. 4 und 5 waagrecht verlaufende Schwenkachse des Filtergriffs 20 in der jeweiligen Bildebene der Fig. 4 und 5 nach oben. Zum einen wird dadurch der Filter 6 mittels des Filtergriffs 20 in dessen Aufnahmelage verriegelt. Zum anderen wird der Schieber 16 mittels des Filtergriffs 20 dabei von dessen in der Fig. 4 dargestellten Blockierlage in dessen in der Fig. 5 dargestellte Freigabelage überführt.In order to properly secure the filter 6 in its receiving position in the filter holder 4, the user transfers the filter handle 20 of the filter 6 from it Fig. 4 shown unlocking position in the Fig. 5 locking position shown. To do this, the user rotates the filter handle 20 in the present exemplary embodiment by one in the respective image plane Fig. 4 and 5 horizontally extending pivot axis of the filter handle 20 in the respective image plane Fig. 4 and 5 up. On the one hand, the filter 6 is locked in its receiving position by means of the filter handle 20. On the other hand, the Slider 16 by means of the filter handle 20 from its in the Fig. 4 shown blocking position in the Fig. 5 released status shown.

Bei der vorgenannten Überführung des Filtergriffs 20 von dessen Entriegelungslage in dessen Verriegelungslage gelangt der Filtergriff 20 zum einen mit dessen Kreisbogenvorsprüngen 24 in Eingriff mit der zu dem jeweiligen Kreisbogenvorsprung 24 korrespondierenden Kreisbogenführung 22 der Filteraufnahme 4. Zum anderen gelangt der Filtergriff 20 dabei mit dessen in der Bildebene der Fig. 1 links dargestellten Kreisbogenvorsprung 24 in Eingriff mit dem Betätigungsvorsprung 26 des Schiebers 16. Der Filtergriff 20 drückt damit den Schieber 16 mittels des letztgenannten Kreisbogenvorsprungs 24 und des Betätigungsvorsprungs 26 entlang der Schieberführung 18 in der jeweiligen Bildebene der Fig. 1 und 3 bis 5 gegen die Federkraft der Feder 14 nach unten, so dass der Schieber 16 von dessen in der Fig. 4 dargestellten Blockierlage in dessen in der Fig. 5 dargestellte Freigabelage überführt wird.During the aforementioned transfer of the filter handle 20 from its unlocking position to its locking position, the filter handle 20, on the one hand, comes into engagement with its circular arc projections 24 with the circular arc guide 22 of the filter holder 4, which corresponds to the respective circular arc projection 24. On the other hand, the filter handle 20 comes into contact with its circular arc projection 24 Image plane of the Fig. 1 The circular arc projection 24 shown on the left engages with the actuating projection 26 of the slide 16. The filter handle 20 thus presses the slide 16 by means of the last-mentioned circular arc projection 24 and the actuating projection 26 along the slide guide 18 in the respective image plane Fig. 1 and 3 to 5 against the spring force of the spring 14 downwards, so that the slide 16 of its in the Fig. 4 shown blocking position in the Fig. 5 The release situation shown is transferred.

Zum besseren Verständnis ist in der jeweiligen Bildebene der Fig. 4 und 5 links ein mit A-A bezeichneter Längsschnitt durch den Schieber 16, in der Mitte ein mit B-B bezeichneter Längsschnitt durch die Kreisbogenführung 22 und rechts die Wäschebehandlungsmaschine 1 im Bereich der Filteraufnahme 4 dargestellt.For better understanding, in the respective image level the Fig. 4 and 5 On the left a longitudinal section marked AA through the slide 16, in the middle a longitudinal section marked BB through the circular arc guide 22 and on the right the laundry treatment machine 1 in the area of the filter holder 4.

Da sich der Filter 6 in dessen Aufnahmelage in der Filteraufnahme 4, der Filtergriff 20 in dessen Verriegelungslage und der Schieber 16 in dessen Freigabelage befindet, kann der Benutzer nun die Klappe 10 von deren in den Fig. 1, 4 und 5 gezeigten Öffnungslage in deren in der Fig. 7 gezeigte Schließlage überführen. Der Benutzer kann anhand der Schließlage der Klappe 10 ohne zusätzliche Hilfsmittel erkennen, dass der Filter 6 in der Filteraufnahme 4 korrekt eingesetzt und mittels des Filtergriffs 20 verriegelt worden ist. Dies ist für einen ordnungsgemäßen und fehlerfreien Betrieb der Wäschebehandlungsmaschine 1 sehr wichtig, da ansonsten die Gefahr bestünde, dass der nicht dargestellte Wärmetauscher der Wäschebehandlungsmaschine 1 mit der Zeit durch Flusen und dergleichen derart verdreckt, dass die Wäschebehandlungsmaschine 1 nicht mehr funktioniert. Aufgrund der sich nun wieder in deren Schließlage befindlichen Klappe 10 ist auch der oben beispielhaft genannte Schalter zur Inbetriebnahme der Wäschebehandlungsmaschine 1 betätigt, so dass der Benutzer die Wäschebehandlungsmaschine 1 jetzt einschalten kann.Since the filter 6 is in its receiving position in the filter holder 4, the filter handle 20 is in its locking position and the slide 16 is in its release position, the user can now move the flap 10 from it into the Fig. 1 , 4 and 5 shown opening position in the Fig. 7 Transfer to the closed position shown. The user can see from the closed position of the flap 10 without additional aids that the filter 6 has been correctly inserted into the filter holder 4 and locked by means of the filter handle 20. This is very important for proper and error-free operation of the laundry treatment machine 1, since otherwise there would be a risk that the heat exchanger, not shown, of the laundry treatment machine 1 would become so dirty over time with lint and the like that the laundry treatment machine 1 would no longer function. Because the flap 10 is now in its closed position again, the switch mentioned above as an example for starting up the laundry treatment machine 1 is also activated, so that the user can now switch on the laundry treatment machine 1.

Im Unterschied zu den bekannten Filteranordnungen und Wäschebehandlungsmaschinen, bei denen die Klappe aufgrund des mittels der Feder vorgespannten Blockierteils mechanisch ständig belastet ist, wird die Klappe 10 aufgrund der erfindungsgemäßen Ausbildung der Filteranordnung für eine Wäschebehandlungsmaschine und der Wäschebehandlungsmaschine gemäß dem vorliegenden Ausführungsbeispiel nicht in ungewünschter Weise durch die Blockiervorrichtung 12 mit dem durch die Feder 14 vorgespannten Blockierteil 16 vorgespannt. Entsprechend ist die erfindungsgemäße Filteranordnung und die erfindungsgemäße Wäschebehandlungsmaschine gemäß dem vorliegenden Ausführungsbeispiel einfacher und damit kostengünstiger im Aufbau und langlebiger.In contrast to the known filter arrangements and laundry treatment machines, in which the flap is constantly mechanically loaded due to the blocking part preloaded by the spring, the flap 10 does not leak in an undesirable manner due to the inventive design of the filter arrangement for a laundry treatment machine and the laundry treatment machine according to the present exemplary embodiment the blocking device 12 with the spring 14 biased blocking part 16 biased. Accordingly, the filter arrangement according to the invention and the laundry treatment machine according to the invention according to the present exemplary embodiment are simpler and therefore cheaper to construct and more durable.

Die Erfindung ist nicht auf das vorliegende Ausführungsbeispiel begrenzt.The invention is not limited to the present exemplary embodiment.

Beispielsweise muss die erfindungsgemäße Wäschebehandlungsmaschine nicht zwingend als ein Wäschetrockner für Textilien oder ein Waschtrockner für Textilien ausgebildet sein. Stattdessen kann die erfindungsgemäße Wäschebehandlungsmaschine in geeigneten und sinnvollen Grenzen als jede Art einer Wäschebehandlungsmaschine ausgebildet sein. Ferner kann die erfindungsgemäße Wäschebehandlungsmaschine auch als ein gewerbliches Gerät, also ein Gerät für den professionellen Einsatz, ausgebildet sein.For example, the laundry treatment machine according to the invention does not necessarily have to be designed as a tumble dryer for textiles or a washer-dryer for textiles. Instead, the laundry treatment machine according to the invention can be designed as any type of laundry treatment machine within suitable and sensible limits. Furthermore, the laundry treatment machine according to the invention can also be designed as a commercial device, i.e. a device for professional use.

Die Erfindung ist insbesondere nicht auf die konstruktiven und fertigungstechnischen Details des erläuterten Ausführungsbeispiels beschränkt. Entsprechend sind die erfindungsgemäße Filteranordnung und die erfindungsgemäße Wäschebehandlungsmaschine auf eine Vielzahl von verschiedenen Anwendungsfällen und Bauformen anpassbar.The invention is in particular not limited to the structural and manufacturing details of the exemplary embodiment explained. Accordingly, the filter arrangement according to the invention and the laundry treatment machine according to the invention can be adapted to a variety of different applications and designs.
