Description

Die Erfindung betrifft einen Wäschetrockner mit einer in einem Gehäuse drehbar gelagerten Trommel, einer mit einer Tür verschließbaren Beschickungsöffnung, sowie einem Gebläse und einer Heizeinrichtung zur Erzeugung eines Prozessluftstromes, der über einen Wärmetauscher strömt, dem ein von außen über eine in der Frontwand des Gehäuses angeordnete Revisionsklappe zugänglicher Filtereinsatz im Strömungskanal vorgeschaltet ist.The invention relates to a tumble dryer with a rotatably mounted in a housing drum, a closable with a door feed opening, and a fan and a heater for generating a process air stream flowing through a heat exchanger, which arranged from the outside via a in the front wall of the housing Inspection flap accessible filter insert is connected upstream in the flow channel.

Aus dem Stand der Technik ist eine Wäschebehandlungsmaschine, insbesondere ein Wäschetrockner, gemäß der EP 2 107 155 A2 bekannt. Bei diesem bekannten Wäschetrockner ist an der Frontseite eine Revisionsklappe vorgesehen, hinter der ein zugänglicher Filtereinsatz im Strömungskanal für die Prozessluft gesetzt werden kann. Der Filtereinsatz besteht aus einem Filterblock zur Filtrierung von Staub, wobei der Filterblock als ein separates Einsatzteil selbstdichtend in den Strömungskanal eingesetzt wird.From the prior art is a laundry treatment machine, in particular a clothes dryer, according to the EP 2 107 155 A2 known. In this known dryer a revision flap is provided on the front, behind which an accessible filter insert can be set in the flow channel for the process air. The filter element consists of a filter block for filtering dust, wherein the filter block is used as a separate insert part self-sealing in the flow channel.

Bei dieser bekannten Ausführungsform wird es als nachteilig angesehen, dass der Filtereinsatzblock durch eine fehlerhafte Handhabung beim Einsetzen die Luftführung im Prozessluftkanal einerseits beeinträchtigen kann bzw. die Effektivität der Filtrierwirkung andererseits in dem Prozessluftkanal eingeschränkt wird.In this known embodiment, it is considered disadvantageous that the filter insert block can affect the air flow in the process air duct on the one hand due to incorrect handling during insertion, or the effectiveness of the filtering effect on the other hand in the process air duct is limited.

Die JP 59 075292 U offenbart einen Wäschetrockner gemäß dem Oberbegriff des Anspruchs 1, mit einer drehbar gelagerten Trommel, einer mit einer Tür verschließbaren Beschickungsöffnung, sowie einem Gebläse zur Erzeugung eines Prozessluftstromes, der über einen Wärmetauscher strömt, dem ein von außen über eine in der Frontwand des Gehäuses angeordneten Revisionsklappe zugänglicher Filtereinsatz im Strömungskanal vorgeschaltet ist. Zur Positionierung bzw. zur Halterung der Filterschicht, besteht der Filtereinsatz aus einem zerlegbaren Gehäuse, das die Filterschicht aufnimmt. Das mit der Filterschicht versehene Gehäuse ist so in den Prozessluftkanal eingesetzt.The JP 59 075292 U discloses a clothes dryer according to the preamble of claim 1, with a rotatably mounted drum, a closable with a door feed opening, and a fan for generating a process air stream which flows through a heat exchanger, the one from the outside via an arranged in the front wall of the housing inspection flap accessible filter insert is connected upstream in the flow channel. For positioning or for holding the filter layer, the filter insert consists of a collapsible housing, which accommodates the filter layer. The housing provided with the filter layer is thus inserted into the process air channel.

Die WO 2005/090669 A2 offenbart einen Wäschetrockner, bei dem ebenfalls ein als Gehäuse ausgebildeter Filtereinsatz in den Prozesskanal eingesetzt ist. Das Gehäuse nimmt hierbei die Filterschicht auf.The WO 2005/090669 A2 discloses a clothes dryer, in which also designed as a housing filter insert is inserted into the process channel. The housing takes on the filter layer.

Die DE 197 05 616 A1 oder die DE 42 20 534 A1 offenbart einen Wäschetrockner, bei dem der Filtereinsatz aus einem Gehäuse bzw. einer Rahmenanordnung besteht, die die Filterschicht aufnimmt und stabilisiert.The DE 197 05 616 A1 or the DE 42 20 534 A1 discloses a clothes dryer in which the filter cartridge consists of a housing or frame assembly which receives and stabilizes the filter layer.

Der Erfindung stellt sich somit die Aufgabe, einen Wäschetrockner derart weiterzubilden, dass die Handhabung des Filtereinsatzes zu Revisionszwecken einfach und sicher im Prozessluftkanal positioniert werden kann.The invention thus has the object of developing a tumble dryer such that the handling of the filter cartridge for revision purposes can be easily and safely positioned in the process air duct.

Erfindungsgemäß wird die Aufgabe durch einen Wäschetrockner mit den Merkmalen des Anspruchs 1 gelöst. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung ergeben sich aus den nachfolgenden abhängigen Ansprüchen.According to the invention the object is achieved by a tumble dryer with the features of claim 1. Advantageous embodiments and modifications of the invention will become apparent from the following dependent claims.

Die mit der Erfindung erreichbaren Vorteile bestehen darin, dass bei der erfindungsgemäßen Lösung der aus einem Filterblock bestehende Filtereinsatz positionssicher in den Prozessluftkanal eingesetzt werden kann. Der Filtereinsatz kann hierbei aus zwei miteinander verbundenen Schaumblöcken bestehen.The advantages that can be achieved with the invention are that, in the solution according to the invention, the filter insert consisting of a filter block can be inserted in a positionally reliable manner into the process air duct. The filter insert can in this case consist of two interconnected foam blocks.

Die Lösung ermöglicht es den Filterblock optimal einzusetzen, wobei dem Betreiber des Wäschetrockners ein fehlerfreies Handling ermöglicht wird. Hierzu ist in der Luftführung des Prozessluftkanals eine Zapfenführung eingebracht, die mit im Träger des Filterblocks vorhandenen Zapfenaufnahmen zusammenwirkt, so dass immer eine zwingende richtige Montage des Filterblocks in der Luftführung bereitgestellt wird. Ein zusätzlicher Verdrehschutz durch Formschluss am Träger sowie am Filterblock unterstützen hierbei den richtigen Ansatz des Filterblocks an den Träger. Eine fehlerhafte Montage des Filterblocks in der Luftführung des Wäschetrockners durch den Betreiber des Wäschetrockners ist dadurch sehr stark erschwert, wobei ein Verschmutzen der Luftführung des Wäschetrockners durch einen fehlerhaften Einbau durch den Betreiber vermieden wird.The solution makes it possible to use the filter block optimally, whereby the operator of the tumble dryer error-free handling is possible. For this purpose, a pin guide is introduced in the air duct of the process air channel, which cooperates with existing in the support of the filter block pin receivers, so that always a compelling proper installation of the filter block is provided in the air duct. An additional torsional protection by positive locking on the carrier and on the filter block support the correct approach of the filter block to the carrier. A faulty installation of the filter block in the air duct of the tumble dryer by the operator of Tumble dryer is characterized very difficult, with a contamination of the air flow of the tumble dryer is avoided by a faulty installation by the operator.

Erfindungsgemäß ist hierbei der Filtereinsatz aus einem wenigstens aus einer Filterschicht bestehenden Filterblock gebildet, der mit einer im Strömungskanal angeordneten Montage und/oder Einsatzhilfe zusammenwirkt. Die Montagehilfe als solches besteht, wie ausgeführt, aus im Strömungskanal angeordneten Zapfen, die mit einem den Filterblock aufnehmenden Träger im eingesetzten Zustand des Filterblocks im Strömungskanal zusammenwirken. Somit wird für den im Querschnitt des Strömungskanals einzusetzenden Filterblock eine exakte Halterung im Strömungsquerschnitt vorgegeben, die das positioniersichere Einsetzen des Filterblockschwammes hier wesentlich vereinfacht. Der Filterblock kann auch aus zwei oder mehreren Filterschichten bestehen, wenn dies für die Stabilität des Filterblocks hilfreich ist.According to the invention, the filter insert is formed from a filter block consisting of at least one filter layer, which cooperates with an assembly and / or insertion aid arranged in the flow channel. The mounting aid as such consists, as stated, of arranged in the flow channel pins which cooperate with a filter block receiving the carrier in the inserted state of the filter block in the flow channel. Thus, an exact support in the flow cross section is specified for the filter block to be used in the cross-section of the flow channel, which substantially simplifies the positioning-safe insertion of the filter block sponge here. The filter block can also consist of two or more filter layers, if this is helpful for the stability of the filter block.

Nach einer vorteilhaften Ausgestaltung der Erfindung besteht der Träger aus zwei über ein Griffelement verbundene Hülsenelemente, die in im Filterblock vorgesehene Durchbrüche greifen. Die Hülsenelemente sind hierbei auf die im Strömungskanal angeordneten Zapfenelemente steckbar. Um eine Formschlussverbindung zwischen den Hülsenelementen und den Zapfenelementen zu schaffen, sind an den Zapfenelementen Nuten angeordnet. In den Hülsenelementen sind hierzu Klemmstege angeformt, die mit den Nuten der Zapfenelemente im gesteckten Zustand des Trägers zusammenwirken. Somit wird im gesteckten Zustand des Trägers auf die Zapfenelemente ein Formschluss gebildet, der hier den Filterblockschwamm in dem Strömungsquerschnitt sicher hält.According to an advantageous embodiment of the invention, the carrier consists of two connected via a handle element sleeve elements which engage in openings provided in the filter block. The sleeve elements are in this case plugged onto the pin elements arranged in the flow channel. In order to create a positive connection between the sleeve elements and the pin elements, grooves are arranged on the pin elements. In the sleeve elements for this purpose clamping webs are formed, which cooperate with the grooves of the pin elements in the inserted state of the carrier. Thus, a positive connection is formed in the inserted state of the carrier on the pin elements, which securely holds the filter block sponge in the flow cross section here.

Nach einer vorteilhaften Ausgestaltung der Erfindung sind an den freien Enden der Hülsenelemente zur Hintergreifung des Öffnungsrandes der Durchbrüche in dem Filterblock bereichsweise Überformungen vorgesehen. Die Überformungen haben den Zweck, dass zunächst der Filterblock auf das losgelöste Trägerelement und auf die Hülsenelemente geklemmt werden kann, wobei die Überformungen ein Selbstlösen des Filterblocks von dem Träger verhindern. Dabei sind an den Hülsenelementen Positionierhilfen für den Filterblock an dem Träger angeformt. Diese bestehen aus angeformten Armen, die eine Anlage für die vordere Filterblockfläche bilden. Dabei besteht auch die Möglichkeit, dass an einem der Arme eine Positionierhilfe in Form eines Zapfens vorgesehen ist, die eine Formschlussverbindung mit einer Bohrung im Filterblock bildet. Hierbei dringt der Zapfen in die Fläche des Filterblocks ein.According to an advantageous embodiment of the invention, portions are provided at the free ends of the sleeve elements for engaging behind the opening edge of the apertures in the filter block. The overshoots have the purpose that first the filter block can be clamped on the detached support member and on the sleeve members, wherein the overshoot prevent self-release of the filter block from the carrier. In this case, positioning aids for the filter block are integrally formed on the sleeve elements on the carrier. These consist of molded arms, which form a system for the front filter block surface. There is also the possibility that a positioning aid in the form of a pin is provided on one of the arms, which forms a positive connection with a bore in the filter block. In this case, the pin penetrates into the surface of the filter block.

Eine andere oder weitere Positionierhilfe wird dadurch bereit gestellt, dass an wenigstens einer der Arme ein Magnet zur Verschlusssicherung angeordnet ist, der im montierten Zustand des Filterblocks ein Signal gibt, dass der Filtereinsatz hier exakt im Prozessluftkanal eingefügt ist. Dies kann zur Bereitstellung einer sicherheitsrelevanten Funktion oder Meldung durch die Steuerung dienen.Another or further positioning aid is provided by the fact that at least one of the arms, a magnet is arranged for locking the lock, which gives a signal in the assembled state of the filter block, that the filter insert is inserted here exactly in the process air duct. This can be used to provide a safety-related function or message by the controller.

Die Figur 1 zeigt in der perspektivischen Darstellung einen Wäschetrockner 1 mit einer in einem Gehäuse 2 nicht näher dargestellten gelagerten Trommel. In der Gehäusevorderwand befindet sich eine Tür 3, die eine Beschickungsöffnung verschließt. In dem Gehäuse 2 befindet sich ein Gebläse und eine Heizeinrichtung zur Erzeugung eines Prozessluftstromes, der über einen Wärmetauscher strömt, dem ein von außen über eine in der Frontwand 4 des Gehäuses 2 angeordnete Revisionsklappe 5 zugänglicher Filtereinsatz 6 im Strömungskanal 7 vorgeschaltet ist. Ein Teilbereich des Strömungskanals 7 ist insbesondere in den Figuren 2 und 3 zu erkennen. Dabei ist der Filtereinsatz 6 aus einem wenigstens aus zwei Filterschichten 6.1 und 6.2 bestehenden Filterblock 8 gebildet, der mit einer im Strömungskanal 7 angeordneten Montage-und/oder Einsatzhilfe 9 zusammenwirkt, wie sie einerseits in der Figur 2 in explosionsartiger Darstellung zu erkennen ist, bzw. in der Figur 3 in der eingesetzten Lage des Filterblocks 8.The FIG. 1 shows in the perspective view of a clothes dryer 1 with a not shown in a housing 2 mounted drum. In the housing front wall is a door 3, which closes a feed opening. In the housing 2 there is a blower and a heater for generating a process air flow, which flows through a heat exchanger, which is preceded by an accessible from the outside via a arranged in the front wall 4 of the housing 2 inspection flap 5 filter insert 6 in the flow channel 7. A portion of the flow channel 7 is in particular in the Figures 2 and 3 to recognize. In this case, the filter element 6 is formed of a filter block 8 consisting of at least two filter layers 6.1 and 6.2, which cooperates with a mounting and / or insertion aid 9 arranged in the flow channel 7, as on the one hand in the FIG. 2 can be seen in an explosive representation, or in the FIG. 3 in the inserted position of the filter block. 8

Die Montagehilfe 9 besteht hierbei aus im Strömungskanal 7 angeordneten Zapfen 10.1 und 10.2, die mit einem den Filterblock 8 aufnehmenden Träger 11 im eingesetzten Zustand des Filterblocks 8 im Strömungskanal 7 zusammenwirken. Diese Situation ist insbesondere in der Figur 3 und 4 dargestellt. Der Träger 11 besteht hierbei aus zwei über ein Griffelement 12 verbundene Hülsenelemente 13.1 und 13.2, wie sie insbesondere in der Figur 2 in der explosionsartigen Darstellung zu erkennen sind. Diese Hülsenelemente 13.1 und 13.2 greifen in die im Filterblock vorgesehenen Durchbrüche 14.1 und 14.2. Die Hülsenelemente 13.1 und 13.2 sind hierbei auf die im Strömungskanal 7 angeordneten Zapfen 10.1 und 10.2 steckbar. Wie aus der Figur 2, aber auch aus der Figur 4 zu erkennen ist, sind an den Zapfen 10.1 und 10.2 Nuten 15 angeordnet. Korrespondierend dazu sind in den Hülsenelementen 13.1 und 13.2 Klemmstege 16 angeformt, die mit den Nuten 15 der Zapfen 10.1 und 10.2 im gesteckten Zustand des Trägers11 zusammenwirken.The assembly aid 9 in this case consists of arranged in the flow channel 7 pins 10.1 and 10.2, which cooperate with a filter block 8 receiving support 11 in the inserted state of the filter block 8 in the flow channel 7. This situation is particular in the FIG. 3 and 4 shown. The carrier 11 consists of two connected via a handle member 12 sleeve elements 13.1 and 13.2, as in particular in the FIG. 2 can be seen in the exploded view. These sleeve elements 13.1 and 13.2 engage in the apertures provided in the filter block 14.1 and 14.2. The sleeve elements 13.1 and 13.2 are in this case plugged onto the arranged in the flow channel 7 pins 10.1 and 10.2. Like from the FIG. 2 , but also from the FIG. 4 can be seen, grooves 15 are arranged on the pins 10.1 and 10.2. Corresponding thereto 13.1 and 13.2 clamping webs 16 are formed in the sleeve members, which cooperate with the grooves 15 of the pins 10.1 and 10.2 in the inserted state of the carrier 11.

Hierbei ist es besonders vorteilhaft für eine sichere Halterung des Filterblocks 8 an dem Träger 11, dass an den freien Enden der Hülsenelemente 13.1 und 13.2 bereichsweise Überformungen 17 vorgesehen sind. Diese werden durch die Durchbrüche 14.1 und 14.2 hindurch geschoben, so dass dann die Überformungen 17 an der Rückseite des Filterblocks 8 den Öffnungsbereich der Durchbrüche 14.1 und 14.2 hintergreifen. Aus der Figur 2, aber auch aus der Figur 5 ist zu erkennen, wo der Träger 11 in isolierter Darstellung mit dem Filterblock 8 dargestellt ist, dass an den Hülsenelementen 13.1 und 13.2 Positionierhilfen für den Filterblock 8 an dem Träger 11 angeformt sind. Die Positionierhilfen bestehen hierbei aus angeformten Armen 18.1, 18.2, 18.3 und 18.4, die eine Anlage für die Filterblockfläche 19 bilden. Dabei befindet sich an dem Arm 18.2 ein angeformter Zapfen 20, der hier im gesteckten Zustand eine Formschlussverbindung mit dem Filterblock 8 eingeht, wobei dieser in eine Öffnung 21 am Filterblock 8 greift, wenn der Träger 11 angesetzt ist. An dem Arm 18.4 ist eine weitere Positionierhilfe vorgesehen, die hier aus einem Magneten 22 gebildet ist, der im gesteckten Zustand zur Überwachung des exakten Sitzes des Filterblocks 8 durch die Steuerung 23 (Fig. 1) dient.It is particularly advantageous for a secure mounting of the filter block 8 on the support 11 that at the free ends of the sleeve members 13.1 and 13.2 partially overshoots 17 are provided. These are pushed through the apertures 14.1 and 14.2, so that then overlaps 17 engage behind the opening portion of the apertures 14.1 and 14.2 at the back of the filter block 8. From the FIG. 2 , but also from the FIG. 5 It can be seen where the carrier 11 is shown in an isolated representation with the filter block 8 that 13.1 and 13.2 positioning aids for the filter block 8 are formed on the carrier 11 to the sleeve elements. The positioning aids in this case consist of integrally formed arms 18.1, 18.2, 18.3 and 18.4, which form a system for the filter block surface 19. In this case, there is on the arm 18.2 a molded pin 20 which enters here in the mated condition a positive connection with the filter block 8, which engages in an opening 21 on the filter block 8 when the carrier 11 is attached. On the arm 18.4 a further positioning aid is provided, which is formed here of a magnet 22, which in the inserted state for monitoring the exact fit of the filter block 8 by the controller 23 (FIG. Fig. 1 ) serves.
