Description

Die Erfindung betrifft eine Flusenfiltereinrichtung für einen Luftstrom in einem Wäschetrockner mit einem endlosen Umlaufelement, welches um zumindest zwei Umlenkelemente umlaufend angeordnet ist und derart positioniert ist, dass es von dem Luftstrom gekreuzt wird, wobei das Umlaufelement einen oberen Rand und einen unteren Rand aufweist. Des Weiteren betrifft die Erfindung auch ein Verfahren zum Reinigen einer derartigen Flusenfiltereinrichtung.The invention relates to a lint filter device for an air flow in a tumble dryer with an endless circulation element, which is arranged circumferentially around at least two deflecting elements and is positioned so that it is crossed by the air flow, wherein the circulation element has an upper edge and a lower edge. Furthermore, the invention also relates to a method for cleaning such a lint filter device.

Wäschetrockner, welche Flusenfiltereinrichtungen aufweisen, sind in vielfältiger Weise bekannt. Die Reinigung dieser Flusenfiltereinrichtung gestaltet sich jedoch meist sehr aufwendig und dennoch unzureichend.Dryers which have lint filter devices are known in many ways. However, the cleaning of this lint filter device is usually very expensive and yet inadequate.

Aus der deutschen Offenlegungsschrift DE 40 23 129 A1 ist ein elektrischer Wäschetrockner bekannt, welcher im Bereich einer Beschickungsöffnung einen dort angeordneten Grobsiebkörper und mit einem dem Grobsiebkörper nachgeschalteten, ortsfest angeordneten Feinsiebkörper aufweist. Der Grobsiebkörper muss zum Entfernen der an dem Feinsiebkörper haftenden Flusen herausgezogen werden. Bei diesem Herausziehen überstreift ein Abstreifer, welcher an dem Grobsiebkörper angeordnet ist, den Feinsiebkörper, wodurch die daran anheftenden Flusen abgenommen werden. Ein Reinigen bzw. ein Abnehmen von Flusen kann hierbei nur dadurch erreicht werden, dass der Grobsiebkörper entfernt wird.From the German patent application DE 40 23 129 A1 an electric clothes dryer is known, which in the region of a feed opening has a Grobsiebkörper arranged there and with a Grobsiebkörper downstream, fixedly arranged Feinsiebkörper. The coarse sieve body must be pulled out to remove the lint adhering to the fine sieve body. During this extraction, a scraper, which is arranged on the Grobsiebkörper strikes the Feinsiebkörper, whereby the adhering thereto lint be removed. Cleaning or removal of lint can be achieved only by removing the coarse sieve body.

Des Weiteren ist aus der DE 44 03 183 C2 ein Wäschetrockner mit einem Flusensieb bekannt. Das Flusensieb ist als feststehendes unbewegliches Element in einem Luftstrom des Wäschetrockners angeordnet. Zur Reinigung bzw. zum Abnehmen der Flusen auf dem Flusensieb ist ein Abstreifer vorgesehen, welcher an seiner dem Abluftkanal abgewandten Seite eine gezahnte Antriebsstange aufweist. Im Eingriff mit der Zahnung der Antriebsstange steht ein Antriebsritzel, das von einem Zahnradgetriebe in Drehung versetzbar ist, wenn ein fest mit der Beschickungstür verbundenes Zahnsegment beim Öffnen der Beschickungstür bewegt wird. Dadurch bewegt sich der Abstreifer über die der Abluft zugewandten Oberfläche des Flusensiebes und streift von ihm Flusen ab. Die Reinigung erfolgt hierbei durch ein automatisches Betätigen des Abstreifers beim Öffnen der Beschickungstür des Wäschetrockners. Auch hier kann das Abnehmen der Flusen vom feststehenden Flusensieb nur sehr unzureichend durchgeführt werden.Furthermore, from the DE 44 03 183 C2 a tumble dryer with a lint filter known. The lint filter is arranged as a fixed immovable element in an air flow of the clothes dryer. For cleaning or for removing the lint on the lint filter, a scraper is provided which has a toothed drive rod on its side facing away from the exhaust duct. Engaging with the toothing of the drive rod is a drive pinion which is rotatable by a gear drive in rotation when a fixedly connected to the loading door gear segment is moved when opening the loading door. As a result, the scraper moves over the surface of the lint filter facing the exhaust air and strips lint from it. The cleaning takes place here by an automatic actuation of the Scraper when opening the loading door of the tumble dryer. Again, the removal of the lint from the fixed lint filter can be performed only very inadequate.

Darüber hinaus ist aus der EP 1 050 619 B1 eine automatisch zu reinigende Flusenfiltereinrichtung für Haushaltswäschetrockner bekannt. Die Flusenfiltereinrichtung umfasst ein endlos um zwei Umlenkelemente umlaufendes Umlaufelement, welches in einem Luftstrom angeordnet ist. Zum Abnehmen der auf dem Umlaufelement anhaftenden Flusen wird das Umlaufelement in Umlaufrichtung bewegt und an einem feststehenden Abstreifer vorbeigeführt. Ist der Reinigungsvorgang des dem Luftstrom zugewandten vorderen Bereichs des Umlaufelements beendet, wird die Drehbewegung der Umlenkelemente umgekehrt, so dass der vordere Bereich des Umlaufelements (dem Luftstrom zugewandte Bereich des Umlaufelements) wieder in seine Ausgangsstellung zurückkehrt. Auch bei dieser Flusenfiltereinrichtung kann der Reinigungsvorgang nur sehr unzureichend und darüber hinaus auch nur sehr aufwendig durchgeführt werden.In addition, from the EP 1 050 619 B1 an automatically cleanable lint filter device for household clothes dryer known. The lint filter device comprises an endlessly circulating around two deflection elements circulating element, which is arranged in an air flow. To remove the adhering to the circulating lint, the circulating element is moved in the direction of rotation and passed a fixed scraper. If the cleaning process of the air flow facing the front portion of the circulating element is completed, the rotational movement of the deflecting elements is reversed, so that the front region of the circulating element (the air flow-facing region of the circulating element) returns to its original position. Even with this lint filter device, the cleaning process can only be carried out very inadequately and moreover also only with great difficulty.

Daher ist es Aufgabe der vorliegenden Erfindung, eine Flusenfiltereinrichtung sowie ein Verfahren zum Reinigen einer derartigen Flusenfiltereinrichtung zu schaffen, welche bzw. welches ein verbessertes und aufwandsarmes Abnehmen der Flusen ermöglicht.It is therefore an object of the present invention to provide a lint filter device and a method for cleaning such a lint filter device, which or which allows an improved and low-cost removal of the lint.

Diese Aufgabe wird durch eine Flusenfiltereinrichtung, welche die Merkmale nach Patentanspruch 1, und ein Verfahren, welches die Merkmale nach Patentanspruch 17 aufweist, gelöst.This object is achieved by a lint filter device having the features according to claim 1, and a method having the features according to claim 17.

Eine erfindungsgemäße Flusenfiltereinrichtung für einen Luftstrom in einem Wäschetrockner weist zumindest zwei Umlenkelemente auf, um die ein endloses Umlaufelement angeordnet ist. Das Umlaufelement ist derart positioniert, dass es von dem Luftstrom gekreuzt wird. Darüber hinaus weist das Umlaufelement einen oberen und einen unteren Rand auf. Ein wesentlicher Gedanke der Erfindung besteht darin, dass zumindest an einem der beiden Ränder erste Eingriffselemente angeordnet sind, welche beim Öffnen einer Beschickungstüre des Wäschetrockners derart in mechanischer Wirkverbindung mit zumindest einem zweiten Eingriffselement stehen bzw. mit diesem mechanisch koppelbar sind, das durch den weiteren Öffnungsvorgang der Beschickungstüre das Umlaufelement automatisch in eine Umlaufrichtung bewegbar und zumindest an einer Vorrichtung zum Abnehmen von Flusen von dem Umlaufelement vorbeiführbar ist. Das zweite Eingriffselement ist im Inneren des Wäschetrockners, insbesondere an der dem Innenraum des Wäschetrockners zugewandten Seite der Beschickungstüre angeordnet. Die bei einer geschlossenen Beschickungstüre entkoppelten ersten und zweiten Eingriffselemente werden gemäß der Erfindung somit bei Öffnen dieser Beschickungstüre mechanisch gekoppelt und durch das weitere Öffnen der Beschickungstüre ein Abnehmen der Flusen von dem Umlaufelement erreicht, da automatisch mit diesem weiteren Öffnungsvorgang der Beschickungstüre das Umlaufelement in Bewegung versetzbar ist und somit an der zumindest einen Vorrichtung zum Abnehmen der Flusen vorbeistreift.A lint filter device according to the invention for an air flow in a tumble dryer has at least two deflection elements around which an endless circulation element is arranged. The circulation element is positioned so that it is crossed by the air flow. In addition, the circulation element has an upper and a lower edge. An essential idea of the invention is that first engaging elements are arranged at least at one of the two edges, which are in mechanical operative connection with at least one second engagement element when opening a loading door of the dryer or are mechanically coupled with this, by the further opening process the feed door, the circulating element automatically in a direction of rotation and at least on a device for removing lint from the circulating element is passable. The second engagement element is arranged in the interior of the tumble dryer, in particular on the side facing the interior of the tumble dryer side of the loading door. The decoupled at a closed loading door first and second engagement elements are thus mechanically coupled according to the invention when opening this Beschickungstüre and achieved by the further opening of the loading door removal of the lint from the circulation element, as automatically with this further opening operation of the loading door, the circulation element set in motion is and thus at the at least one device for removing the fluff passes by.

Durch die erfindungsgemäße Flusenfiltereinrichtung kann in aufwandsarmer und auch in zuverlässiger Weise ein stets optimaler Reinigungsvorgang der Flusenfiltereinrichtung erreicht werden. Durch das Koppeln des Öffnungsvorgangs mit einem dann automatischen Bewegen des Umlaufelements erfolgt stets ein effizientes Abnehmen der Flusen. Insbesondere kann dadurch auch erreicht werden, dass durch das Weiterbewegen des Umlaufelements nicht nur eine Reinigung der dem Luftstrom zugewandten Seite des Umlaufelements erreicht werden kann, sondern dass auch für einen nächsten Trocknungsvorgang ein anderer Bereich des Umlaufelements dem Luftstrom zugewandt ist. Diesbezüglich kann somit auch ein stetiger Wechsel der Teilbereiche des Umlaufelements durchgeführt werden, welche in nachfolgenden Trocknungsvorgängen dem Luftstrom zugewandt sind. Dadurch kann ein übermäßiges Verschleißen des Umlaufelements verhindert werden.By means of the lint filter device according to the invention, an always optimal cleaning process of the lint filter device can be achieved in a low-effort and also in a reliable manner. By coupling the opening operation with a then automatic movement of the circulating element is always an efficient removal of lint. In particular, this can also be achieved by not only a cleaning of the air flow side facing the circulation element can be achieved by the further movement of the circulating element, but that another area of the circulating element faces the air flow for a next drying process. In this regard, therefore, a continuous change of the portions of the circulating element can be performed, which are facing the air flow in subsequent drying operations. As a result, excessive wear of the circulation element can be prevented.

In bevorzugter Weise sind die ersten Eingriffselemente als Rastnasen ausgebildet. Das zweite Eingriffselement kann vorteilhafterweise stabförmig ausgebildet sein und an seiner dem ersten Eingriffselement zugewandten Ende hakenförmig ausgebildet sein. Dadurch können zwei sehr einfach herstellbare und zuverlässig koppelbare Eingriffselemente geschaffen werden, welche das Koppeln und Entkoppeln bzw. das Erzeugen der mechanischen Wirkverbindung beim Öffnen der Beschickungstüre aufwandsarm und sicher gewährleisten können. Der Eingriff des hakenförmigen Endes in eine Rastnase stellt einen unkomplizierten Kopplungsmechanismus dar.In a preferred manner, the first engagement elements are designed as latching lugs. The second engagement element may advantageously be designed rod-shaped and be hook-shaped on its end facing the first engagement element. As a result, two engagement elements which are very easy to produce and reliably coupleable can be created, which can ensure the coupling and decoupling or the generation of the mechanical operative connection when opening the loading door with little effort and safety. The engagement of the hook-shaped end in a latching nose is an uncomplicated coupling mechanism.

In vorteilhafter Weise sind sowohl am oberen Rand als auch am unteren Rand des Umlaufelements erste Eingriffselemente ausgebildet und zwei zweite Eingriffselemente im Inneren des Wäschetrockners bevorzugt derart positioniert, dass eines der zweiten Eingriffselemente zum Eingriff mit den ersten Eingriffselementen am oberen Rand und eines der zweiten Eingriffselemente zum Eingriff mit dem ersten Eingriffselement am unteren Rand des Umlaufelements ausgebildet sind. Dadurch kann erreicht werden, dass stets ein über die gesamte Höhe des Umlaufelements gleichmäßiges Bewegen des Umlaufelements erfolgt und somit ein Verklemmen des Umlaufelements verhindert werden kann. Darüber hinaus kann auch ein Verschleiß reduziert werden, welcher bei einem Eingriff lediglich am oberen Rand oder lediglich am unteren Rand auftreten kann.In an advantageous manner, first engagement elements are formed both on the upper edge and on the lower edge of the circulation element, and two second engagement elements are preferably positioned in the interior of the tumble dryer such that one of the second Engagement elements are formed for engagement with the first engagement elements at the upper edge and one of the second engagement elements for engagement with the first engagement element at the lower edge of the circulation element. As a result, it can be achieved that a movement of the circulatory element that is uniform over the entire height of the circulating element is always effected, and thus jamming of the circulatory element can be prevented. In addition, a wear can be reduced, which can occur in an engagement only at the top or only at the bottom.

Darüber hinaus kann durch diese doppelte Ausbildung auch ein redundantes System geschaffen werden, welches auch dann sicher und zuverlässig ein Weiterbewegen des Umlaufelements beim Öffnen der Beschickungstüre gewährleistet, wenn unerwarteter Weise an dem oberen Rand oder an dem unteren Rand eine mechanische Kopplung zwischen dem dortigen ersten Eingriffselement und dem zugeordneten zweiten Eingriffselement nicht erfolgreich ist.In addition, a redundant system can be created by this dual training, which ensures safe and reliable continued movement of the circulating element when opening the loading door, if unexpectedly at the upper edge or at the bottom of a mechanical coupling between the local first engagement element and the associated second engagement element is unsuccessful.

In vorteilhafter Weise ist die mechanische Wirkverbindung zwischen den ersten und zweiten Eingriffselementen derart ausgebildet, dass beim Öffnungsvorgang der Beschickungstüre des Wäschetrockners das Umlaufelement im Wesentlichen um die Hälfte der Gesamtlänge des Umlaufelements weiter bewegbar ist. Damit kann erreicht werden, dass nach jedem zweiten Öffnen der Beschickungstüre wieder der gleiche Teilbereich des Umlaufelements dem Luftstrom zugewandt angeordnet ist.Advantageously, the mechanical operative connection between the first and second engagement elements is designed such that during the opening process of the loading door of the tumble dryer, the circulating element is substantially further movable by half the total length of the circulating element. It can thus be achieved that, after every second opening of the loading door, the same subregion of the circulating element is again arranged facing the air flow.

In vorteilhafter Weise ist die Vorrichtung zum Abnehmen von Flusen als Abstreifer oder als Bürste ausgebildet. Es kann auch vorgesehen sein, dass zumindest zwei Abstreifer und/oder Bürsten oder zumindest ein Abstreifer und zumindest eine Bürste angeordnet sind. In bevorzugter Weise ist die Vorrichtung zum Abnehmen von Flusen im Wesentlichen parallel zu den Umlenkelementen angeordnet und relativ bewegbar zum Umlaufelement ausgebildet. Die Vorrichtung zum Abnehmen von Flusen ist dabei bevorzugt so groß ausgebildet, dass ihre Länge der Höhe des Umlaufelements entspricht. Dadurch kann gewährleistet werden, dass beim Bewegen des Umlaufelements die gesamte Höhe zwischen dem oberen und dem unteren Rand des Umlaufelements von der Vorrichtung zum Abnehmen von Flusen erfasst wird und die Flusen im gesamten Bereich zuverlässig entfernt werden können. Durch die relative Bewegbarkeit der Vorrichtung zum Abnehmen von Flusen gegenüber dem Umlaufelement kann eine weitere Verbesserung des Reinigungsvorgangs erzielt werden.Advantageously, the device for removing lint is designed as a scraper or as a brush. It can also be provided that at least two scrapers and / or brushes or at least one scraper and at least one brush are arranged. Preferably, the device for removing lint is arranged substantially parallel to the deflecting elements and designed to be relatively movable relative to the circulating element. The device for removing lint is preferably formed so large that its length corresponds to the height of the circulating element. This can ensure that when moving the circulation element, the entire height between the upper and the lower edge of the circulation element is detected by the device for removing lint and the lint can be reliably removed in the entire area. Due to the relative mobility of the device for removing lint against the circulation element, a further improvement of the cleaning process can be achieved.

Durch ein gezieltes Bewegen der Vorrichtung zum Abnehmen von Flusen gegenüber dem Umlaufelement kann an besonders kritischen Stellen somit ein individuelles Reinigen der Teilbereich des Umlaufelements zielsicher und zuverlässig durchgeführt werden.By a targeted movement of the device for removing fluff relative to the circulating element, an individual cleaning of the subregion of the circulating element can thus be carried out in a unerring and reliable manner at particularly critical points.

In bevorzugter Weise ist die Vorrichtung zum Abnehmen von Flusen entgegen der beim Öffnungsvorgang der Beschickungstüre bewirkbaren Umlaufrichtung des Umlaufelements bewegbar. Durch diese gegenläufige Bewegung des Umlaufelements und der Vorrichtung zum Abnehmen von Flusen kann eine besonders effektive und effiziente Durchführung des Reinigungsvorgangs des Umlaufelements erreicht werden.In a preferred manner, the device for removing fluff is movable counter to the direction of rotation of the circulating element that can be effected during the opening process of the loading door. By this opposite movement of the circulating element and the device for removing lint, a particularly effective and efficient implementation of the cleaning process of the circulating element can be achieved.

Die Vorrichtung zum Abnehmen von Flusen ist beim Öffnungsvorgang der Beschickungstüre mit dem zweiten Eingriffselement bevorzugterweise derart koppelbar, dass die Bewegung der Vorrichtung zum Abnehmen der Flusen durch den Öffnungsvorgang der Beschickungstüre automatisch bewirkbar ist. Dadurch kann durch den ohnehin durchzuführenden Öffnungsvorgang sowohl die Betätigung des Umlaufelements als auch die Betätigung der Vorrichtung zum Abnehmen, insbesondere in entgegengesetzten Bewegungsrichtungen, automatisch erreicht werden.The device for removing lint is preferably coupled with the second engagement element during the opening process of the loading door such that the movement of the device for removing the lint is automatically effected by the opening operation of the loading door. As a result, both the actuation of the circulation element and the actuation of the device for removal, in particular in opposite directions of movement, can be achieved automatically by the opening process to be carried out anyway.

In vorteilhafter Weise kann vorgesehen sein, dass die Vorrichtung zum Abnehmen von Flusen nach einem Reinigungsvorgang des Umlaufelements über eine Reinigungsvorrichtung zum Säubern der Vorrichtung zum Abnehmen von Flusen bewegbar ist. Dadurch kann auch die Entfernung der Flusen von der Vorrichtung zum Abnehmen der Flusen stets sicher erreicht werden. Die Vorrichtung zum Abnehmen von Flusen kann somit bei jedem nachfolgenden Reinigungsvorgang des Umlaufelements sauber bereit gestellt werden, wodurch auch der Reinigungsvorgang des Umlaufelements positiv beeinflussbar ist.Advantageously, it can be provided that the device for removing fluff after a cleaning operation of the circulating element via a cleaning device for cleaning the device for removing lint is movable. Thereby, the removal of the lint from the device for removing the lint can always be achieved safely. The device for removing lint can thus be provided clean ready for each subsequent cleaning operation of the circulation element, whereby the cleaning process of the circulation element is positively influenced.

Die Reinigungsvorrichtung ist in vorteilhafter Weise als kammähnliches Element ausgebildet. An der Innenseite der Beschickungstüre ist in vorteilhafter Weise ein Flusenauffangbereich ausgebildet, in welchen die durch die Reinigungsvorrichtung von der Vorrichtung zum Abnehmen von Flusen entfernten Flusen sammelbar sind. Dieser Flusenauffangbereich kann bevorzugt eine Öffnungsklappe zum Entfernen der Flusen aus dem Flusenauffangbereich aufweisen. Es kann auch vorgesehen sein, dass der Flusenauffangbereich von der Flusenfiltereinrichtung gelöst werden kann und aus dem Wäschetrockner entfernt werden kann.The cleaning device is advantageously designed as a comb-like element. On the inside of the loading door, a lint collecting area is advantageously formed, in which the lint removed by the cleaning device from the device for removing lint can be collected. This lint collecting area may preferably have an opening flap for removing the lint from the lint collecting area. It can also be provided that the Flusenauffangbereich can be solved by the lint filter and can be removed from the tumble dryer.

Die Öffnungsklappe kann über ein Betätigungselement vorteilhafterweise betätigbar sein, wobei das Betätigungselement im oberen Bereich der Verkleidung der Beschickungstüre angeordnet sein kann. In einer vorteilhaften Ausgestaltung weist die Flusenfiltereinrichtung eine Einheit zum Erkennen des Befüllungsgrades des Flusenauffangbereichs auf, welche zum automatischen Anzeigen, insbesondere durch ein optisches und/oder akustisches Signal, eines erforderlichen Leerens des Flusenauffangbereichs ausgebildet ist. Dadurch kann sicher erkannt werden, wann das Leeren des Flusenauffangbereichs erfolgen soll. Ein Überfüllen und somit Verstopfen des Flusenauffangbereichs kann dadurch verhindert werden.The opening flap can advantageously be actuated via an actuating element, wherein the actuating element can be arranged in the upper region of the lining of the loading door. In an advantageous embodiment, the lint filter device has a unit for detecting the degree of filling of the lint collection area, which is designed for automatic display, in particular by an optical and / or acoustic signal, of a required emptying of the lint collection area. As a result, it can be reliably detected when the emptying of the lint collecting area should take place. Overfilling and thus clogging of the lint collection area can be prevented.

Zwischen einem vorderen Umlaufbereich und einem hinteren Umlaufbereich des Umlaufelements kann ein Kunststoffelement angeordnet sein. Das Umlaufelement kann als Siebgewebe ausgebildet sein. Das Siebgewebe und das Kunststoffelement können dabei unterschiedliche Körnungen im Hinblick auf den Durchlass von Flusen aufweisen.Between a front circulation area and a rear circulation area of the circulating element, a plastic element can be arranged. The circulating element can be designed as a mesh screen. The screen fabric and the plastic element may have different grain sizes with regard to the passage of lint.

Vorteilhafterweise sind die Umlenkelemente in einer Innenverkleidung der Beschickungstüre angeordnet.Advantageously, the deflecting elements are arranged in an inner lining of the loading door.

Bei dem erfindungsgemäßen Verfahren zum Reinigen einer Flusenfiltereinrichtung für einen Luftstrom in einem Wäschetrockner, welcher eine Beschickungstüre aufweist; wobei die Flusenfiltereinrichtung zumindest zwei Umlenkelemente umfasst, um welche ein endloses Umlaufelement umlaufend angeordnet ist, wird beim Öffnen der Beschickungstüre eine mechanische Wirkverbindung zwischen ersten Eingriffselementen, welche zumindest an einem oberen oder an einem unteren Rand des Umlaufelements angeordnet sind, und einem zweiten, im Inneren des Wäschetrockners angeordneten Eingriffselement, erzeugt. Durch den weiteren Öffnungsvorgang der Beschickungstüre wird das Umlaufelement in einer Umlaufrichtung aufgrund der bestehenden Wirkverbindung zwischen zumindest einem ersten und dem zweiten Eingriffselement automatisch weiterbewegt und an einer Vorrichtung zum Abnehmen von Flusen derart vorbeigeführt, dass die Flusen von dem Umlaufelement entfernt werden. Durch das erfindungsgemäße Verfahren wird durch die Kopplung der Bewegung des Umlaufelements abhängig von dem Öffnungsvorgang der Beschickungstüre ein aufwandsarmes und zuverlässiges Entfernen der Flusen von dem Umlaufelement erreicht.In the method according to the invention for cleaning a lint filter device for an air flow in a tumble dryer, which has a feed door; wherein the lint filter means comprises at least two deflecting elements around which an endless circulation element is arranged circumferentially, a mechanical operative connection between first engagement elements, which are arranged at least at an upper or at a lower edge of the circulation element, and a second, in the interior when opening the loading door the tumble dryer arranged engagement element generated. As a result of the further opening process of the loading door, the circulation element is automatically moved further in a circulation direction due to the existing operative connection between at least one first and the second engagement element and past a device for removing lint such that the lint is removed from the circulation element. By the method according to the invention is the coupling of the movement of the circulating element depending on the opening process of the Loading door achieved a low-effort and reliable removal of the lint from the circulation element.

Die Vorrichtung zum Abnehmen von Flusen wird während des Öffnungsvorgangs der Beschickungstüre in entgegengesetzter Richtung zur Umlaufrichtung des Umlaufelements automatisch bewegt. Indem sowohl das Umlaufelement als auch die Vorrichtung zum Abnehmen von Flusen bewegt werden, kann das Reinigen des Umlaufelements nochmals verbessert werden.The device for removing lint is automatically moved during the opening operation of the loading door in the opposite direction to the circulation direction of the circulation element. By moving both the circulation element and the device for removing lint, the cleaning of the circulation element can be further improved.

Vorteilhafte Ausgestaltungen der Flusenfiltereinrichtung können auch als vorteilhafte Ausgestaltungen des erfindungsgemäßen Verfahrens angesehen werden.Advantageous embodiments of the lint filter device can also be regarded as advantageous embodiments of the method according to the invention.

Die Erfindung wird nachfolgend anhand schematischer Zeichnungen näher erläutert. Es zeigen:

Fig. 1
eine Draufsichtdarstellung auf eine erfindungsgemäße Flusenfiltereinrichtung; und
Fig. 2
eine perspektivische Darstellung einer erfindungsgemäßen Flusenfiltereinrichtung.
The invention will be explained in more detail with reference to schematic drawings. Show it:
Fig. 1
a top view of a lint filter device according to the invention; and
Fig. 2
a perspective view of a lint filter device according to the invention.

In den Figuren werden gleiche oder funktionsgleiche Elemente mit den gleichen Bezugszeichen versehen.In the figures, identical or functionally identical elements are provided with the same reference numerals.

Die schematische Draufsichtdarstellung in Fig. 1 zeigt eine Flusenfiltereinrichtung 1, welche in einem nicht dargestellten Wäschetrockner angeordnet ist. Die Flusenfiltereinrichtung 1 ist in einem Luftstrom S angeordnet, derart, dass der Luftstrom S die Flusenfiltereinrichtung 1 kreuzt. Im Ausführungsbeispiel ist die Flusenfiltereinrichtung 1 im Wesentlichen senkrecht zum Luftstrom S orientiert.The schematic plan view in FIG Fig. 1 shows a lint filter device 1, which is arranged in a clothes dryer, not shown. The lint filter device 1 is arranged in an air flow S such that the air flow S crosses the lint filter device 1. In the exemplary embodiment, the lint filter device 1 is oriented substantially perpendicular to the air flow S.

Der Luftstrom S des Wäschetrockners wird üblicherweise über das zu trocknende und in dem Wäschetrockner befindliche Wäschegut geführt, wobei dabei der Luftstrom S dem Wäschegut Feuchtigkeit entzieht und Flusen F mitreißen kann, die sich an anderer Stelle des Wäschetrockners absetzen können und daher entfernt werden müssen. Der die Flusen 5 mitführende Luftstrom S tritt im Ausführungsbeispiel gemäß Fig. 1 von rechts in die Flusenfiltereinrichtung 1 ein und wird in einem Luftkanal K waagrecht und gerade geführt. Die Flusenfiltereinrichtung 1 weist ein endloses Umlaufelement 2 auf, welches im Ausführungsbeispiel als Endlosband ausgebildet ist. Dieses Umlaufelement 2 wird im Ausführungsbeispiel von zwei Umlenkelementen 3 und 4 gehalten und gespannt, wobei das Umlaufelement 2 derart kreuzend zum Luftstrom S angeordnet ist, dass die gerade gespannten Bereiche (in Fig. 1 vertikal orientierten Bereiche des Umlaufelements 2) im Wesentlichen senkrecht zum Luftstrom S gehalten werden.The air flow S of the tumble dryer is usually performed on the laundry to be dried and located in the dryer laundry, while the air flow S the laundry dehumidifies and entrain fluff F, which can settle elsewhere in the dryer and therefore must be removed. The lint 5 accompanying airflow S occurs in the embodiment according to Fig. 1 from the right in the lint filter device 1 and is guided horizontally and straight in an air channel K. The lint filter device 1 has an endless circulation element 2, which in the embodiment is designed as an endless belt. This circulating element 2 is held and tensioned in the embodiment of two deflecting elements 3 and 4, wherein the circulating element 2 is arranged so crossing to the air flow S, that the just strained areas (in Fig. 1 vertically oriented areas of the circulating element 2) are held substantially perpendicular to the air flow S.

Die Umlenkelemente 3 und 4 sind drehbeweglich gelagert, wobei wenigstens eines dieser beiden Umlenkelemente 3 und 4 im oder gegen den Uhrzeigersinn angetrieben werden kann.The deflection elements 3 and 4 are rotatably mounted, wherein at least one of these two deflection elements 3 and 4 can be driven in the clockwise or counterclockwise direction.

Das Umlaufelement 2 weist einen unteren Rand (nicht dargestellt) und einen oberen Rand 21 auf. Sowohl an dem unteren Rand als auch an dem oberen Rand 21 sind im Ausführungsbeispiel erste Eingriffselemente 211 angebracht. Wie dabei zu erkennen ist, sind im Ausführungsbeispiel in Fig. 1 eine Mehrzahl dieser ersten Eingriffselemente 211 beabstandet zueinander um den gesamten oberen Rand 21 angeordnet. Die als schwarze Rechtecke schematisch gekennzeichneten ersten Eingriffselemente 211 sind im Ausführungsbeispiel als Rastnasen ausgebildet. In entsprechender Weise sind derartige Rastnasen auch am unteren Rand des Umlaufelements 2 ausgebildet.The circulating element 2 has a lower edge (not shown) and an upper edge 21. Both at the lower edge and at the upper edge 21, first engagement elements 211 are mounted in the embodiment. As can be seen thereby are in the embodiment in Fig. 1 a plurality of these first engagement elements 211 spaced from each other around the entire upper edge 21 arranged. In the exemplary embodiment, the first engagement elements 211, which are schematically indicated as black rectangles, are designed as latching lugs. In a corresponding manner, such locking lugs are also formed at the lower edge of the circulating element 2.

Des Weiteren ist in schematischer Weise eine Vorrichtung 5 zum Abnehmen von Flusen F von der Oberseite des Umlaufelements 2 angeordnet. Diese Vorrichtung 5 zum Abnehmen von Flusen F ist im Ausführungsbeispiel bewegbar angeordnet und insbesondere relativ bewegbar zum Umlaufelement 2 ausgebildet.Furthermore, a device 5 for removing fluff F from the top of the circulating element 2 is arranged in a schematic manner. This device 5 for removing lint F is arranged movably in the exemplary embodiment and in particular is designed to be relatively movable relative to the circulation element 2.

In Fig. 1 ist zu erkennen, dass ein Flusenauffangbereich 6 ausgebildet ist. Nach einem Reinigungsvorgang des Umlaufelements 2 kann die Vorrichtung 5 zum Abnehmen von Flusen F über eine nicht dargestellte Reinigungsvorrichtung zum Säubern der Vorrichtung 5 bewegbar angeordnet sein und über diese Reinigungsvorrichtung bewegt werden, derart, dass die in der Vorrichtung 5 angesammelten Flusen F entfernt werden und durch die Reinigungsvorrichtung, welche als kammähnliches Element ausgebildet sein kann, in den Flusenauffangbereich 6 sammelbar sind.In Fig. 1 It can be seen that a lint collection area 6 is formed. After a cleaning operation of the circulating element 2, the device 5 for removing fluff F can be arranged movably via a cleaning device, not shown, for cleaning the device 5 and moved over this cleaning device, such that the lint F accumulated in the device 5 are removed and through the cleaning device, which may be formed as a comb-like element, are collectable in the lint collection area 6.

Sowohl die Flusenfiltereinrichtung 1, als auch die Vorrichtung 5, als auch der Flusenauffangbereich 6 sind im Ausführungsbeispiel an einer Innenseite einer Beschickungstüre (nicht dargestellt) des Wäschetrockners angeordnet.Both the lint filter device 1, as well as the device 5, and the lint collection area 6 are arranged in the embodiment on an inside of a loading door (not shown) of the clothes dryer.

Die Umlenkelemente 3 und 4 sind im Ausführungsbeispiel im Wesentlichen parallel zueinander angeordnet und zylinderförmig ausgebildet. Die Längsachsen der Umlenkelemente 3 und 4 sind senkrecht zur Figurenebene angeordnet.The deflection elements 3 and 4 are arranged in the embodiment substantially parallel to each other and cylindrical. The longitudinal axes of the deflecting elements 3 and 4 are arranged perpendicular to the plane of the figure.

Das Umlaufelement 2 ist zumindest teilweise aus einem Filtergewebe bzw. einem Siebgewebe ausgebildet, welches ein weitmaschiges Netz aus dünnen, glatten Fäden sein kann.The circulating element 2 is at least partially formed from a filter fabric or a mesh fabric, which may be a wide-meshed network of thin, smooth threads.

Die ersten Eingriffselemente 211 sind in der gezeigten Darstellung gemäß Fig. 1 mechanisch entkoppelt bzw. ohne mechanische Wirkverbindung zu zweiten Eingriffselementen (nicht dargestellt), welche im Ausführungsbeispiel im Inneren des Wäschetrockners angeordnet sind.The first engagement elements 211 are shown in the illustration shown Fig. 1 mechanically decoupled or without mechanical operative connection to second engagement elements (not shown), which are arranged in the interior of the tumble dryer in the embodiment.

Die Wirkungsweise der erfindungsgemäßen Filtervorrichtung 1 wird nachfolgend mit der perspektivischen Darstellung in Fig. 2 erläutert. Dort ist zu erkennen, dass das Umlaufelement 2 auch an seinem unteren Rand 22 erste Eingriffselemente 221 aufweist. Darüber hinaus sind in Fig. 2 auch die im Ausführungsbeispiel zwei zweiten Eingriffselemente 7 und 8 in schematischer Weise gezeigt. Wie dabei zu erkennen ist, sind diese zweiten Eingriffselemente 7 und 8 stabförmig ausgebildet und weisen an ihren, den ersten Eingriffselementen 211 bzw. 221 zugewandten Endbereichen hakenförmige Enden 71 bzw. 81 auf. Über diese hakenförmigen Enden 71 und 81 kann eine mechanische Kopplung zwischen den zweiten Eingriffselementen 7 und 8 und den ersten Eingriffselementen 211 und 221 erzeugt werden.The operation of the filter device 1 according to the invention is described below with the perspective view in Fig. 2 explained. It can be seen there that the circulation element 2 also has first engagement elements 221 at its lower edge 22. In addition, in Fig. 2 Also shown in the embodiment, two second engagement elements 7 and 8 in a schematic manner. As can be seen, these second engagement elements 7 and 8 are rod-shaped and have hook-shaped ends 71 and 81 at their end areas facing the first engagement elements 211 and 221, respectively. Through these hook-shaped ends 71 and 81, a mechanical coupling between the second engagement elements 7 and 8 and the first engagement elements 211 and 221 can be generated.

Befindet sich der Wäschetrockner im geschlossenen Zustand, ist auch die Beschickungstüre des Wäschetrockners geschlossen. In diesem geschlossenen Zustand sind die ersten Eingriffselemente 211 und 221 ohne Wirkverbindung und somit ohne mechanische Kopplung zu den zweiten Eingriffselementen 7 und 8. Wird nun nachfolgend die Beschickungstüre geöffnet, so wird automatisch ein Eingriff und somit eine mechanische Wirkverbindung zwischen dem hakenförmigen Ende 71 und einem der ersten Eingriffselemente 211 am oberen Rand 21 des Umlaufelements 2 erzeugt. In analoger Weise wird eine mechanische Kopplung zwischen dem hakenförmigen Ende 81 des zweiten Eingriffselements 8 mit einem ersten Eingriffselement 221 am unteren Rand 22 des Umlaufelements 2 erzeugt. Dieser Eingriff bzw. diese mechanische Wirkverbindung wird unmittelbar beim Öffnen der Beschickungstüre hergestellt. Wir nun nachfolgend die Beschickungstüre in einem weiteren Öffnungsvorgang weiter geöffnet, so ist die Flusenfiltereinrichtung 1 derart ausgebildet, dass das Umlaufelement 2 im Ausführungsbeispiel in Richtung des Pfeils PF1 bewegt wird. Dies erfolgt dadurch, dass die zweiten Eingriffselemente 7 und 8 und insbesondere die hakenförmigen Enden 71 und 81 durch den Öffnungsvorgang der Beschickungstüre in diese Richtung bewegt werden. Aufgrund der mechanischen Kopplung zwischen den zweiten Eingriffselementen 7 und 8 mit den ersten Eingriffselementen 211 und 221 wird folglich auch das Umlaufelement 2 durch den Öffnungsvorgang der Beschickungstüre automatisch in Richtung des Pfeils PF1 bewegt.If the tumble dryer is in the closed state, the loading door of the tumble dryer is also closed. In this closed state, the first engagement elements 211 and 221 are without operative connection and thus without mechanical coupling to the second engagement elements 7 and 8. If now the loading door is opened, then automatically engaging and thus a mechanical operative connection between the hook-shaped end 71 and a the first engagement elements 211 generated at the upper edge 21 of the circulating element 2. In Analogously, a mechanical coupling between the hook-shaped end 81 of the second engagement element 8 with a first engagement element 221 at the lower edge 22 of the circulation element 2 is generated. This engagement or mechanical operative connection is made immediately upon opening the loading door. If the loading door is subsequently opened further in a further opening process, then the lint filter device 1 is designed such that the circulation element 2 is moved in the direction of the arrow PF1 in the exemplary embodiment. This is done by moving the second engaging elements 7 and 8 and in particular the hook-shaped ends 71 and 81 in this direction by the opening operation of the loading door. Consequently, due to the mechanical coupling between the second engagement elements 7 and 8 with the first engagement elements 211 and 221, the circulation element 2 is also automatically moved in the direction of the arrow PF1 by the opening operation of the loading door.

Im Ausführungsbeispiel wird bei einem Öffnungsvorgang der Beschickungstüre, welcher von einer minimalen Öffnung bis zu einer maximal möglichen Öffnung der Beschickungstüre reicht, das Umlaufelement 2 im Wesentlichen um die Hälfte seiner Gesamtlänge weiterbewegt. Dies bedeutet, dass während eines derartigen Öffnungsvorgangs der ursprünglich dem Luftstrom S zugewandte Teilbereich des Umlaufelements 2 praktisch vollständig nach hinten bewegt wird und somit auf der dem Luftstrom S abgewandten Seite positioniert ist, wenn die Beschickungstüre vollständig geöffnet ist.In the exemplary embodiment, in an opening operation of the loading door, which extends from a minimum opening to a maximum possible opening of the loading door, the circulation element 2 is moved substantially by half of its total length. This means that during such an opening operation, the portion of the circulating element 2 initially facing the air flow S is moved almost completely to the rear and is thus positioned on the side facing away from the air flow S when the loading door is completely open.

In Fig. 2 ist die Vorrichtung 5 zum Abnehmen der Flusen F benachbart zum Umlenkelement 3 angeordnet. Wie aus der Darstellung in Fig. 2 zu erkennen ist, erstreckt sich die Vorrichtung 5 zumindest über die gesamte Höhe des Umlaufelements 2. Die Höhe des Umlaufelements 2 wird dabei durch die Ausmaße des Umlaufelements 2 zwischen dem oberen Rand 21 und dem unteren Rand 22 definiert. Im Ausführungsbeispiel ist diese Vorrichtung 5 relativ bewegbar zum Umlaufelement 2 ausgebildet. Die Vorrichtung 5 ist ebenfalls mit dem Öffnungsvorgang der Beschickungstüre derart in Wirkverbindung, dass während dem Öffnen der Beschickungstüre von einer minimalen Öffnungsstellung in eine maximale Öffnungsstellung eine Bewegung in Richtung des Pfeils PF2 erfolgt. Im Ausführungsbeispiel ist diese mechanische Kopplung derart, dass während dieses Öffnungsvorgangs der Beschickungstüre die Vorrichtung 5 vollständig vom in Fig. 2 gezeigten Zustand bis in eine entsprechende Position benachbart zum Umlenkelement 4 bewegt wird. Die Vorrichtung 5 wird somit über den gesamten Weg zwischen dem Umlenkelement 3 und dem Umlenkelement 4 in Richtung des Pfeils PF2 bewegt. Im Ausführungsbeispiel wird somit bei dem Öffnungsvorgang der Beschickungstüre eine entgegengesetzte Bewegung zwischen dem Umlaufelement 2 und der Vorrichtung 5 automatisch bewirkt. Indem die Vorrichtung 5 zumindest während der Bewegung des Umlaufelements 2 dieses Umlaufelement 2 berührt, werden die an der Oberseite des Umlaufelements 2 angesammelten Flusen F entfernt.In Fig. 2 the device 5 for removing the lint F is arranged adjacent to the deflection element 3. As from the illustration in Fig. 2 can be seen, the device 5 extends at least over the entire height of the circulating element 2. The height of the circulating element 2 is defined by the dimensions of the circulating element 2 between the upper edge 21 and the lower edge 22. In the exemplary embodiment, this device 5 is designed to be relatively movable relative to the circulation element 2. The device 5 is also in operative connection with the opening process of the loading door such that during opening of the loading door from a minimum open position to a maximum open position, movement takes place in the direction of the arrow PF2. In the exemplary embodiment, this mechanical coupling is such that during this opening operation of the loading door, the device 5 is completely removed from the in Fig. 2 shown state is moved to a corresponding position adjacent to the deflecting element 4. The device 5 is thus moved over the entire path between the deflecting element 3 and the deflecting element 4 in the direction of the arrow PF2. In the embodiment, an opposite movement between the circulating element 2 and the device 5 is thus automatically effected during the opening process of the loading door. By the device 5, at least during the movement of the circulating element 2, touching this circulating element 2, the lint F accumulated on the upper side of the circulating element 2 is removed.

Im Ausführungsbeispiel ist die Bewegungsmöglichkeit der Vorrichtung 5 in Pfeilrichtung PF2 und auch in entgegengesetzter Richtung gemäß des Pfeils PF1 derart, dass sie über die Anordnung der Umlenkelemente 3 bzw. 4 hinausbewegt werden kann. An der dem Umlenkelement 3 abgewandten Seite des Umlenkelements 4 ist eine nicht dargestellte Reinigungsvorrichtung angeordnet, welche im Ausführungsbeispiel ein kammähnliches Element ist. In analoger Weise ist auch an der dem Umlenkelement 4 abgewandten Seite des Umlenkelements 3 ein weiteres derartiges kammähnliches Element positioniert. Durch Bewegen der Vorrichtung 5 über diese kammähnlichen Elemente können die in der Vorrichtung 5 aufgesammelten Flusen abgestreift werden. Diese von diesem kammähnlichen Element abfallenden Flusen gelangen dann in den Flusenauffangbereich 6 (Fig. 1) und werden dort gesammelt.In the embodiment, the possibility of movement of the device 5 in the direction of arrow PF2 and also in the opposite direction according to the arrow PF1 is such that it can be moved beyond the arrangement of the deflection elements 3 and 4 respectively. On the side facing away from the deflecting element 3 of the deflecting element 4, a cleaning device, not shown, is arranged, which is a comb-like element in the embodiment. In an analogous manner, another such comb-like element is also positioned on the side facing away from the deflecting element 4 of the deflecting element 3. By moving the device 5 over these comb-like elements, the lint collected in the device 5 can be scraped off. These flakes falling off this comb-like element then enter the lint collecting area 6 (FIG. Fig. 1 ) and are collected there.

Dieser Flusenauffangbereich 6 weist eine Öffnung auf, welche im Ausführungsbeispiel an der Unterseite bzw. der Bodenseite 61 (Fig. 1) des Flusenauffangbereichs 6 ausgebildet ist. Diese Öffnung, welche als Klappe ausgebildet sein kann, kann im Ausführungsbeispiel durch ein nicht dargestelltes Betätigungselements, welches im oberen Bereich der Verkleidung der Beschickungstüre angeordnet sein kann, betätigt. Das Betätigungselement kann beispielsweise eine Drucktaste sein. Die in dem Flusenauffangbereich 6 angesammelten Flusen F fallen dann heraus und in einen bereitgestellten Behälter hinein, beispielsweise einen Abfalleimer.This lint collecting area 6 has an opening, which in the exemplary embodiment on the underside or the bottom side 61 (FIG. Fig. 1 ) of the lint collection area 6 is formed. This opening, which may be formed as a flap, in the embodiment by an unillustrated actuating element, which may be arranged in the upper region of the lining of the loading door, actuated. The actuator may be, for example, a push button. The lint F accumulated in the lint collection area 6 then falls out and into a provided container, for example a trash can.

Im Ausführungsbeispiel weist der Wäschetrockner eine Einheit, beispielsweise einen Sensor auf, mit der der Befüllungsgrad des Flusenauffangbereichs 6 überwacht wird und ein möglicher Überfüllungszustand frühzeitig optisch und/oder akustisch angezeigt werden kann. Dabei wird signalisiert, dass der Flusenauffangbereich 6 demnächst zu leeren ist. Es kann dabei vorgesehen sein, dass dies etwa bei zehn Trocknungsvorgängen gegeben ist und eine derartige Warnung nach etwa zehn Trocknungsvorgängen erzeugt wird. Selbstverständlich ist diese Zahl lediglich beispielhaft und kann bspw. abhängig von der Größe des Flusenauffangbereichs 6 deutlich davon abweichen.In the exemplary embodiment, the tumble dryer has a unit, for example a sensor, with which the degree of filling of the lint collection area 6 is monitored and a possible overfill condition can be indicated optically and / or acoustically early. It is signaled that the lint collection area 6 is about to empty soon. It can be provided that this is approximately at ten Drying operations is given and such a warning is generated after about ten drying operations.
