Description

Die Erfindung betrifft eine Flusenfiltervorrichtung für ein Hausgerät, insbesondere einen Wäschetrockner oder einen Waschtrockner, welche einen ersten Flusenfilter und zumindest einen zweiten Flusenfilter umfasst. Des Weiteren betrifft die Erfindung ein Hausgerät zur Pflege von Wäschestücken mit einer derartigen Flusenfiltervorrichtung.The invention relates to a lint filter device for a domestic appliance, in particular a tumble dryer or a washer-dryer, which comprises a first lint filter and at least one second lint filter. Furthermore, the invention relates to a household appliance for the care of laundry with such a lint filter device.

Es sind Wäschetrockner bekannt, bei denen lediglich ein Flusensieb als Flusenfilter eingesetzt ist. Bei Wäschetrocknern, welche eine Wärmepumpe aufweisen, wird zum Schutz der fein laminierten Wärmetauscher der Wärmepumpe üblicherweise ein zweites Flusensieb bzw. ein zweiter Flusenfilter eingesetzt. Die beiden Flusenfilter sind als separate Komponenten ausgebildet und an unterschiedlichen Orten im Hausgerät positioniert. Für die ordnungsgemäße Funktionalität ist es erforderlich, dass beide Flusensiebe nach einer bestimmten Betriebsdauer des Hausgeräts regelmäßig gereinigt werden.There are known tumble dryer, in which only a lint filter is used as lint filter. In tumble dryers which have a heat pump, a second lint filter or a second lint filter is usually used to protect the finely laminated heat exchanger of the heat pump. The two lint filters are designed as separate components and positioned at different locations in the household appliance. For proper functionality it is necessary that both fluff filters be cleaned regularly after a certain period of use of the appliance.

Aufgrund der örtlichen Positionierung ist ein Flusensieb beim Entladen und Beladen des Trockners meist im Blickfeld des Nutzers, so dass aufgrund der leichteren Zugänglichkeit und mit dem Erkennen des Flusensiebs auch das Bewusstsein beim Nutzer im Hinblick auf dessen Reinigung gegeben ist. Das weitere Flusensieb ist meist nur über eine separate Klappe, die üblicherweise auch noch relativ tief am Aufstellboden des Hausgeräts angebracht ist, zu erreichen. Dadurch tritt die Reinigung dieses Flusensiebs nicht unmittelbar in das Bewusstsein des Nutzers und wird häufig vergessen. Dies führt zu einer Funktionsbeeinträchtigung des Hausgeräts. Gerade die Wartung dieses zweiten Flusensiebs ist jedoch wichtig, da sich meist in diesem die feineren Flusen absetzen und die Luftwege dort nach mehrmaligen Betriebszyklen relativ stark zusetzen, so dass die Luftmenge gedrosselt wird. Nicht zuletzt dadurch wird somit auch das Betriebsverhalten des Hausgeräts im Hinblick auf den Energieverbrauch und den Zeitbedarf für ein Reinigungsprogramm verschlechtert.Due to the local positioning a lint filter during unloading and loading of the dryer is usually in the field of view of the user, so that due to the easier accessibility and with the recognition of the lint filter and the awareness of the user in terms of its cleaning is given. The other lint filter is usually only accessible via a separate flap, which is usually also mounted relatively low on the floor of the home appliance. As a result, the cleaning of this lint filter does not directly enter the user's consciousness and is often forgotten. This leads to a functional impairment of the domestic appliance. Just the maintenance of this second lint filter is important, however, since usually settle in this the finer lint and enforce the airways there relatively strong after repeated operating cycles, so that the amount of air is throttled. Not least of all, the operating behavior of the domestic appliance is thus also worsened with regard to the energy consumption and the time required for a cleaning program.

Es ist Aufgabe der vorliegenden Erfindung, die Handhabbarkeit einer Flusenfiltervorrichtung mit mehreren Flusenfiltern zu vereinfachen und insbesondere die Reinigungsmöglichkeit zu verbessern.It is an object of the present invention to simplify the handling of a lint filter device with a plurality of lint filters and in particular to improve the possibility of cleaning.

Diese Aufgabe wird durch eine Flusenfiltervorrichtung, welche die Merkmale nach Patentanspruch 1 aufweist, und ein Hausgerät, welches die Merkmale nach Patentanspruch 6 aufweist, gelöst.This object is achieved by a lint filter device having the features of claim 1, and a domestic appliance having the features of claim 6.

Eine erfindungsgemäße Flusenfiltervorrichtung für ein Hausgerät umfasst einen ersten Flusenfilter und zumindest einen weiteren zweiten Flusenfilter. Die beiden Flusenfilter sind miteinander verbunden und dennoch relativ zueinander bewegbar. Durch eine derartige Ausgestaltung der Flusenfiltervorrichtung kann ein zusammenhängendes Gesamtkonstrukt geschaffen werden, welches einfach und aufwandsarm aufgrund der flexiblen Bewegbarkeit an spezifischen Orten im Hausgerät angebracht und von dort wieder entnommen werden kann. Darüber hinaus sind die mehreren Flusenfilter stets zusammenhängend und liegen zu Reinigungszwecken grundsätzlich in ihrer Vollständigkeit vor. Auch bei einer Mehrzahl von Flusenfiltern werden somit stets alle gereinigt und Flusenfilter, welche an nicht im Blickfeld liegenden Positionen im Hausgerät angeordnet sind, werden im Hinblick auf die Reinigung doch nicht vergessen. Nicht zuletzt kann dadurch auch das Betriebsverhalten des Hausgeräts wesentlich verbessert werden.A lint filter device according to the invention for a domestic appliance comprises a first lint filter and at least one further second lint filter. The two lint filters are connected to each other and still movable relative to each other. By such a configuration of the lint filter device, a coherent overall construct can be created, which can be easily and inexpensively mounted due to the flexible mobility at specific locations in the household appliance and removed from there again. In addition, the plurality of lint filters are always connected and are generally available for cleaning purposes in their entirety. Even with a plurality of lint filters, therefore, all are always cleaned and lint filters, which are arranged at positions not lying in the field of view in the domestic appliance, are not forgotten in terms of cleaning. Last but not least, the operating behavior of the household appliance can be significantly improved thereby.

Vorzugsweise sind die beiden Flusenfilter durch eine Gelenkvorrichtung miteinander verbunden. Die Gelenkvorrichtung kann relativ einfach aufgebaut sein und einen Verbindungsarm, ggf. auch mehrere solcher Verbindungsarme, aufweisen, welcher drehbar an einem Flusenfilter angeordnet bzw. gelagert ist. Außer einer Platz sparenden und dennoch hoch flexiblen Verbindungskonstruktion kann dadurch auch ein sehr bauteilminimiertes und somit kostengünstiges Konzept ermöglicht werden.Preferably, the two lint filters are interconnected by a hinge device. The hinge device may be of relatively simple construction and may have a connecting arm, possibly also a plurality of such connecting arms, which is rotatably arranged or mounted on a lint filter. In addition to a space-saving, yet highly flexible connection construction, a very component-minimized and thus cost-effective concept can thereby be made possible.

Vorzugsweise sind die beiden Flusenfilter beabstandet zueinander angeordnet. Gerade dadurch kann den Anforderungen im Hinblick auf die örtliche Positionierung der jeweiligen Flusenfilter im Hausgerät Rechnung getragen werden und dennoch die mechanische Verbindung beibehalten werden. Auch kann durch diese Positionierung die relative Beweglichkeit zueinander sehr flexibel ermöglicht werden.Preferably, the two lint filters are spaced from one another. Precisely because of the requirements with regard to the local positioning of the respective lint filter in the household appliance can be taken into account and still maintain the mechanical connection. Also, the relative mobility to each other can be made very flexible by this positioning.

Vorzugsweise ist die Verbindung zwischen den beiden Flusenfiltern so ausgebildet, dass diese translatorisch und/oder rotatorisch relativ zueinander bewegbar sind.Preferably, the connection between the two lint filters is designed so that they are translationally and / or rotationally movable relative to each other.

Ein erfindungsgemäßes Hausgerät zur Pflege von Wäschestücken, insbesondere ein Wäschetrockner oder ein Waschtrockner, umfasst eine erfindungsgemäße Flusenfiltervorrichtung oder eine vorteilhafte Ausgestaltung davon.An inventive household appliance for the care of laundry items, in particular a clothes dryer or a washer-dryer, comprises a lint filter device according to the invention or an advantageous embodiment thereof.

Vorzugsweise ist der erste Flusenfilter in einem Lagerschild des Hausgeräts angeordnet.Preferably, the first lint filter is arranged in a bearing plate of the household appliance.

Der zweite Flusenfilter ist vorzugsweise in Strömungsrichtung der Prozessluft im Hausgerät vor einem Wärmetauscher angeordnet. Insbesondere dann, wenn das Hausgerät mit einer Wärmepumpe ausgebildet ist, ist dieser zweite Flusenfilter vor der Wärmepumpe positioniert. Die sehr feinen Flusen können dadurch ausgefiltert werden und die Luftwege durch die Wärmepumpe werden nicht durch diese feineren Flusen zugesetzt.The second lint filter is preferably arranged in the flow direction of the process air in the domestic appliance in front of a heat exchanger. In particular, when the domestic appliance is designed with a heat pump, this second lint filter is positioned in front of the heat pump. The very fine lint can be filtered out and the air passages through the heat pump are not added by these finer lint.

Vorzugsweise ist die gesamte Flusenfiltervorrichtung über einen gemeinsamen Schacht des Hausgeräts, insbesondere über das Lagerschild, entnehmbar und auch über dieses wieder einsetzbar.The entire lint filter device can preferably be removed via a common shaft of the domestic appliance, in particular via the end shield, and can also be reused therefor.

In Fig. 1 ist ein senkrecht geschnittener Kondensationstrockner 1 gezeigt, welcher nachfolgend als Trockner 1 bezeichnet wird. Der dargestellte Trockner 1 weist eine um eine horizontale Achse drehbare Trommel 3 auf, welche als Trocknungskammer ausgebildet ist. Innerhalb der Trommel 3 sind Mitnehmer 4 zur Bewegung von Wäsche während einer Trommeldrehung befestigt. Prozessluft wird mittels eines ersten Gebläses 19 über eine Heizung 18 durch die Trommel 3, einen Luft-Luft-Wärmetauscher 11, 12 sowie eine Wärmepumpe 13, 14, 15 in einem Luftkanal 2 im geschlossenen Kreis geführt (Prozessluftkreis 2). Nach Durchgang durch die Trommel 3 wird die feuchte, warme Prozessluft abgekühlt und nach Kondensation der in der Prozessluft enthaltenen Feuchtigkeit wieder erwärmt. Dabei wird von der Heizung 18, welche einstufig oder mehrstufig sein kann, erwärmte Luft von hinten, d. h. von der einer Trocknertür 5 gegenüberliegenden Seite der Trommel 3, durch deren gelochten Boden in die Trommel 3 geleitet. Von dort kommt diese Prozessluft mit der zu trocknenden Wäsche in Berührung und strömt durch die Befüllöffnung der Trommel 3 zu einem Flusensieb 6 innerhalb der die Befüllöffnung verschließenden Trocknertür 5. Anschließend wird der Luftstrom in der Trocknertür 5 nach unten umgelenkt und von dem Luftkanal 2 zum Luft-Luft-Wärmetauscher 11, 12 geleitet. Dort kondensiert infolge der Abkühlung die von der Prozessluft aus den Wäschestücken aufgenommene Feuchtigkeit und wird in einem in Fig. 1 gestrichelt gezeichneten Kondensat-Behälter 21 aufgefangen, von dem aus sie entsorgt werden kann.In Fig. 1 a vertically cut condensation dryer 1 is shown, which is referred to below as the dryer 1. The dryer 1 shown has a drum 3 rotatable about a horizontal axis, which is designed as a drying chamber. Within the drum 3, drivers 4 are mounted for moving laundry during a drum rotation. Process air is conducted by means of a first blower 19 via a heater 18 through the drum 3, an air-air heat exchanger 11, 12 and a heat pump 13, 14, 15 in an air duct 2 in a closed circuit (process air circuit 2). After passage through the drum 3, the moist, warm process air is cooled and reheated after condensation of moisture contained in the process air. In this case, from the heater 18, which may be single-stage or multi-stage, heated air from the rear, ie from the dryer door 5 opposite side of the drum 3, passed through the perforated bottom in the drum 3. From there, this process air comes into contact with the laundry to be dried and flows through the filling opening of the drum 3 to a lint filter 6 inside the drying door closing the filling opening 5. Subsequently, the air flow in the dryer door 5 is deflected downwards and from the air duct 2 to the air Air heat exchanger 11, 12 passed. There condenses due to the cooling of the process air from the laundry absorbed moisture and is in a in Fig. 1 dashed drawn condensate tank 21 collected from which they can be disposed of.

Anschließend wird die etwas abgekühlte Prozessluft zu einem Verdampfer 13 der Wärmepumpe 13, 14, 15 geführt, wo sie weiter abgekühlt wird. Das dabei im Verdampfer 13 verdampfte Kältemittel dieser Wärmepumpe 13, 14, 15 wird über einen Kompressor 14 zu einem Verflüssiger 15 geleitet. Im Verflüssiger 15 verflüssigt sich das Kältemittel unter Wärmeabgabe an die Prozessluft. Das nun in flüssiger Form vorliegende Kältemittel wird anschließend zu einem Drosselventil 17 geführt und über dieses Drosselventil 17 wieder zum Verdampfer 13 geleitet, wodurch der Kältemittelkreis geschlossen ist. Die Kühlluft wird der Raumluft entnommen und nach Durchgang durch den Luft-Luft-Wärmetauscher 11, 12 wieder der Raumluft zugeführt. Die Luftzirkulation durch den Luft-Luft-Wärmetauscher 11, 12 wird durch ein zweites Gebläse 20 erzeugt.Subsequently, the somewhat cooled process air is led to an evaporator 13 of the heat pump 13, 14, 15, where it is further cooled. The refrigerant vaporized in the evaporator 13 of this heat pump 13, 14, 15 is conducted via a compressor 14 to a condenser 15. In the condenser 15, the refrigerant liquefies under Heat emission to the process air. The now present in liquid refrigerant is then fed to a throttle valve 17 and passed through this throttle valve 17 back to the evaporator 13, whereby the refrigerant circuit is closed. The cooling air is taken from the room air and, after passing through the air-to-air heat exchanger 11, 12 again supplied to the room air. The air circulation through the air-to-air heat exchanger 11, 12 is generated by a second blower 20.

Die Trommel 3 ist in der in Fig. 1 gezeigten Ausführungsform am hinteren Boden mittels eines Drehlagers und vorne mittels eines Lagerschilds 7 gelagert, wobei die Trommel 3 mit einer Krempe auf einem Gleitstreifen 8 am Lagerschild 7 aufliegt und so am vorderen Ende gehalten wird. Die Steuerung des Kondensationstrockners erfolgt über eine Steuereinrichtung 10, die vom Benutzer über eine Bedieneinheit 9 geregelt werden kann.The drum 3 is in the in Fig. 1 shown embodiment at the rear bottom by means of a pivot bearing and mounted in front by means of a bearing plate 7, wherein the drum 3 rests with a brim on a sliding strip 8 on the bearing plate 7 and is held at the front end.

Die Flusenfiltervorrichtung 26 ist in einen für die Flusenfilter 6 und 24 gemeinsamen Schacht 34 eingeführt und in die Fig. 3 gezeigte Endposition gebracht.In Fig. 3 is in contrast to the representation according to Fig. 1 not a sectional view as viewed from the side of the dryer 1, but a sectional view with a view from the front shown. In Fig. 3 For example, a positional state of the completely inserted lint filter device 26 in the dryer 1 is shown. The lint filter device 26 is inserted into a common for the lint filter 6 and 24 and shaft 34 in the Fig. 3 brought shown end position.

In Fig. 4 ist eine zur Fig. 3 entsprechende Schnittdarstellung gezeigt, wobei diesbezüglich bereits eine teilweise Entnahmeposition der Flusenfiltervorrichtung 26 dargestellt ist. Ausgehend von der eingesetzten Endposition gemäß der Darstellung in Fig. 3 ist hier die Flusenfiltervorrichtung 26 bereits teilweise über den gemeinsamen Schacht 34 nach oben gezogen. Durch die Gelenkvorrichtung 27 kann auch eine nicht geradlinige vertikale Entnahme nach oben ermöglicht werden, da ein Verschwenken der Flusensiebe bzw. Flusenfilter 6 und 24 relativ zueinander möglich ist und auch bei einem gekrümmten Schacht 34 oder eines nicht geradlinigen Entnahmewegs eine einfache Entnahme möglich ist.In Fig. 4 is one to Fig. 3 corresponding sectional view shown, in this regard, a partial removal position of the lint filter device 26 is already shown. Starting from the inserted end position as shown in Fig. 3 here is the lint filter device 26 already partially pulled over the common shaft 34 upwards. By the hinge device 27 also a non-linear vertical removal can be made possible upwards, since a pivoting of the lint filters or lint filters 6 and 24 relative to each other is possible and even in a curved Shaft 34 or a non-linear removal path easy removal is possible.

In Fig. 5 ist dann ein weiterer Zwischenzustand im Hinblick auf die Entnahme der Flusenfiltervorrichtung 26 gezeigt, wobei diesbezüglich der erste Flusenfilter 6 bereits vollständig aus dem Schacht 34 und somit auch aus dem Lagerschild 7 entfernt ist.In Fig. 5 is then shown a further intermediate state with regard to the removal of the lint filter device 26, in this regard, the first lint filter 6 is already completely removed from the shaft 34 and thus also from the bearing plate 7.

In Fig. 6 ist dann der vollständig entnommene Zustand der Flusenfiltervorrichtung 26 gezeigt, welche in Fig. 6 nicht mehr dargestellt ist. Ausgehend von der Darstellung gemäß Fig. 6 kann dann auch wieder ein einfaches Einfügen bzw. Einsetzen der gesamten Flusenfiltervorrichtung 26 nach dem Reinigen der Flusenfilter 6 und 24 ermöglicht werden, bis der Endzustand gemäß Fig. 3 wieder erreicht ist.In Fig. 6 Then, the completely removed state of the lint filter device 26 is shown, which in Fig. 6 is no longer shown. Starting from the illustration according to Fig. 6 can then also be a simple insertion or insertion of the entire lint filter device 26 after cleaning the lint filter 6 and 24 are enabled until the final state according to Fig. 3 is reached again.
