Description

Gebiet der ErfindungField of the invention

Die Erfindung betrifft ein Haushaltsgerät, insbesondere einen Wäschetrockner, sowie ein Verfahren zum Betreiben eines solchen Haushaltsgeräts.The invention relates to a household appliance, in particular a tumble dryer, and a method for operating such a household appliance.

Hintergrundbackground

Wäschetrockner trocknen die in einen Trocknungsraum, beispielsweise eine Trommel, eingebrachten feuchten oder nassen Textilien durch Zufuhr warmer, trockener Luft in den Trocknungsraum. Die warme Luft nimmt die Feuchtigkeit aus den Textilien auf. Die so mit Feuchtigkeit gesättigte Abluft wird beispielsweise einem Wärmetauscher zugeführt. Im Wärmetauscher wird die warme, feuchte Luft abgekühlt und gibt die Feuchte in Form von Wasser in ein Sammelbecken ab. Nachfolgend wird die immer noch feuchte, kühle Luft erwärmt und getrocknet und gewährleistet so eine bessere Feuchteaufnahme im Trocknungsraum. Diese trockene, warme Luft wird wiederum dem Trocknungsraum zugeführt.Dryers dry the wet or wet fabrics introduced into a drying room, such as a drum, by supplying warm, dry air into the drying room. The warm air absorbs the moisture from the textiles. The saturated with moisture exhaust air is supplied, for example, a heat exchanger. In the heat exchanger, the warm, humid air is cooled and releases the moisture in the form of water into a collection basin. Subsequently, the still moist, cool air is heated and dried, thus ensuring a better moisture absorption in the drying room. This dry, warm air is in turn fed to the drying room.

In dem geschlossenen Luftkreislauf eines solchen sogenannten Kondensationstrockners ist zwischen Trocknungsraumaustritt und Wärmetauschereintritt typischerweise ein auch als Flusensieb bekannter Luftfilter angeordnet zum Abscheiden von Partikeln aus dem Luftstrom im Allgemeinen und von Textilflusen im Besonderen. Im Trocknungsvorgang selbst nimmt die trockene, warme Luft nicht nur wie erwünscht die Feuchtigkeit der zu trocknenden Textilien auf sondern auch Textilpartikel wie Flusen oder andere Abscheidungen des Trocknungsgutes bedingt durch die mechanische Beanspruchung der Textilien durch den Luftstrom, die Trommelrotation, etc.. Ohne das vorgenannte Filter können Strukturen des nachfolgenden Wärmetauschers durch ebensolche Partikel verschmutzt werden.In the closed air cycle of such a so-called condensation dryer, an air filter, also known as a lint filter, is typically arranged between the drying chamber outlet and the heat exchanger inlet for separating particles from the air stream in general and from textile fluff in particular. In the drying process itself, the dry, warm air takes not only as desired the moisture of the textiles to be dried but also textile particles such as lint or other deposits of the material due to the mechanical stress of the textiles by the air flow, the drum rotation, etc .. Without the above Filters structures of the subsequent heat exchanger can be contaminated by just such particles.

Ein solches Filter ist bevorzugt an der Innenseite einer Beschickungstüre des Wäschetrockners angeordnet, welche Beschickungstüre, im Folgenden auch nur Türe genannt, Zugang zum Trocknungsraum erlaubt. Damit die Funktion eines solchen Filters nicht beeinträchtigt wird, ist dieses regelmässig zu reinigen. Dazu, aber auch zum leichteren Austausch des Filters soll selbiges von der Türe lösbar ausgestaltet sein.Such a filter is preferably arranged on the inside of a loading door of the tumble dryer, which loading door, hereinafter also referred to as a door, allows access to the drying room. To ensure that the function of such a filter is not impaired, it must be cleaned regularly. In addition, but also for easier replacement of the filter selbiges should be made detachable from the door.

Die DE 32 19 977 A1 zeigt einen Wäschetrockner mit einem Grobsieb und einem Feinsieb in einer Türe des Wäschetrockners. Das Grobsieb ist über einen Zapfen drehend an der Türe gelagert und kann bei Bedarf um 180 Grad abgeschwenkt werden. Das Feinsieb ist gegenüber dem Grobsieb ortsfest angeordnet und mit einer Schweiss-, Einspritz-, Schnapp- oder Rastverbindung an der Türe gehalten. Das Grobsieb kann mit einer mit der Tür zusammenwirkenden Rasteinrichtung oder einem Magnetverschluss versehen sein, um es gegen ein unbeabsichtigtes Verschwenken aus seiner Betriebsstellung zu sichern.The DE 32 19 977 A1 shows a clothes dryer with a coarse filter and a fine screen in a door of the clothes dryer. The coarse screen is rotatably mounted on the door via a pin and can be swiveled 180 degrees, if necessary. The fine screen is stationary relative to the coarse screen and held with a welding, injection, snap or locking connection to the door. The coarse screen may be provided with a latching means cooperating with the door or a magnetic closure to secure it against inadvertent pivoting out of its operative position.

Die EP 2 309 053 A1 zeigt einen Wäschetrockner, bei dem ein sogenannter Filterblock dem Kondensator im Sockel des Geräts vorgeschaltet ist, welcher Filterblock aus zusammengeklebten Filterelementen besteht. Dieser Filterblock weist einen Magneten in einer Nut auf, der mit einem ortsfesten Sensor den Betrieb des Wäschetrockners nur zulässt, wenn der Filterblock exakt eingebaut ist.The EP 2 309 053 A1 shows a clothes dryer, in which a so-called filter block is connected upstream of the capacitor in the base of the device, which filter block consists of glued together filter elements. This filter block has a magnet in a groove, which allows the operation of the tumble dryer with a stationary sensor only if the filter block is installed exactly.

Die DE 91 04 967 U1 zeigt einen Wäschetrockner mit einem Grobsieb und einem Feinsieb in einer Türe des Wäschetrockners sowie einen einem Kondensator vorgeschalteten Filterblock.The DE 91 04 967 U1 shows a clothes dryer with a coarse filter and a fine screen in a door of the clothes dryer and a capacitor block upstream filter block.

Die DE 103 02 974 A1 behandelt die Problematik, dass bei verstopftem Flusensieb in der Türe ein Rückstau der flusenbehafteten Luft entstehen kann und diese Luft rückwärts durch den Lufteinlass der Trommel diese wieder verlassen kann, was unerwünscht sei. Daher wird vorgeschlagen, am Lufteinlass, also am rückseitigen Ende der Trommel, ein Filter anzuordnen. Die Befestigung könne mit Rast- oder mit Magnetelementen erfolgen.The DE 103 02 974 A1 deals with the problem that with clogged lint filter in the door, a backflow of lint-laden air can occur and this air backwards through the air inlet of the drum leave them again, which is undesirable. Therefore, it is proposed to arrange a filter at the air inlet, ie at the rear end of the drum. The attachment can be done with detent or with magnetic elements.

Die DE 40 23 129 A1 zeigt einen Wäschetrockner mit einem Grobsiebkörper im Bereich der Beschickungsöffnung und mit einem dem Grobsiebkörper nachgeschalteten und ortsfest angeordneten Feinsiebkörper. Der Grobsiebkörper ist zur Entfernung der an dem Feinsiebkörper anhaftenden Flusen herausziehbar angeordnet und mit einem Abstreifer versehen.The DE 40 23 129 A1 shows a clothes dryer with a Grobsiebkörper in the region of the feed opening and with a Grobsiebkörper downstream and fixedly arranged Feinsiebkörper. The coarse sieve body is arranged to be removable in order to remove the lint adhering to the fine sieve body and provided with a wiper.

Die DE 10 2008 045525 A1 zeigt ein Filterelement für einen Wäschetrockner mit einem Magneten, der mit einem Magnetschalter zusammenwirkt. Das Filterelement ist im Ablufttrakt einer Auslassöffnung der Trommel nachfolgend und damit stationär im Korpus angeordnet. Alternativ zur magnetischen Erkennung wird auch eine optische oder mechanische Erkennung angegeben. Wird festgestellt, dass das Filterelement fehlt, so wird der Betrieb des Wäschetrockners nicht freigegeben oder der Benutzer gewarnt.The DE 10 2008 045525 A1 shows a filter element for a clothes dryer with a magnet which cooperates with a magnetic switch. The filter element is in the exhaust air tract of an outlet opening of the drum below and thus arranged stationary in the body. As an alternative to magnetic detection, an optical or mechanical recognition is also indicated. If it is determined that the filter element is missing, the operation of the tumble dryer will not be released or the user will be warned.

Die US 5 097 606 A beschreibt eine ähnliche Filterüberwachung mit einem Filter im Korpus des Wäschetrockners.The US 5 097 606 A describes a similar filter monitoring with a filter in the body of the tumble dryer.

Darstellung der ErfindungPresentation of the invention

Es stellt sich vor diesem Hintergrund die Aufgabe, eine verbesserte Filteranordnung für ein Haushaltsgerät bereitzustellen. Diese Aufgabe wird von der Vorrichtung und von dem Verfahren gemäss der unabhängigen Patentansprüche gelöst.It is against this background the object to provide an improved filter assembly for a household appliance. This object is achieved by the device and the method according to the independent claims.

Bei dem erfindungsgemässen Haushaltsgerät, welches Haushaltsgerät insbesondere ein Wäschetrockner oder ein Waschautomat mit integrierter Trocknungsfunktion ist, ist ein Filter durch eine magnetische Haltekraft an einer Türe des Haushaltsgeräts gehalten, welche Türe zum Öffnen und Schliessen des Trocknungsraumes dient. In einer Betriebsposition des Filters, also in einer durch die magnetische Haltekraft an der Türe gehaltenen Position des Filters, wird bei geschlossener Türe im Trocknungsbetrieb ein Prozessluftstrom aus dem Trocknungsraum durch das Filter geführt, und der Prozessluftstrom dadurch von Partikeln und insbesondere Flusen befreit.In the inventive household appliance, which household appliance is in particular a tumble dryer or a washing machine with integrated drying function, a filter is held by a magnetic holding force to a door of the household appliance, which door is used to open and close the drying room. In an operating position of the filter, that is, in a position held by the magnetic holding force on the door position of the filter, a process air flow from the drying space is passed through the filter with the door closed in the drying operation, and the process air flow thereby freed of particles and especially lint.

Durch das Verwenden einer magnetischen Haltekraft wird das Lösen des Filters von der Türe wesentlich erleichtert, da das Filter manuell durch Überwinden der magnetischen Haltekraft von der Türe lösbar ist. Dabei kann das Filter an jeder beliebigen Stelle vom Benutzer angegriffen werden. Auch ein Wiedereinsetzen des Filters gestaltet sich einfach, da das Filter nur in etwa an seine Betriebsposition geführt werden muss. Das Überführen in seine letztendliche Betriebsposition kann aufgrund der magnetischen Anziehung ohne weiteren manuellen Eingriff erfolgen. Dies gilt insbesondere auch dann, wenn das Filter beispielsweise zwischen ein weiteres Filter und die Türe eingelegt wird, welches weitere Filter vorzugsweise über einen Klappmechanismus wie ein Scharnier mit der Türe verbunden ist. Dann nähert sich das Filter durch Zuklappern des weiteren Filters an seine Betriebsposition an, wobei ebenfalls das Überführen des Filters in seine letztendliche Betriebsposition durch die magnetische Anziehung erfolgt. Das Scharnier des weiteren Filters mag dabei als Auflager für das Filter dienen, sodass das Filter in dieser Weiterbildung in seiner Betriebsposition durch das Auflager und die magnetische Haltekraft gehalten wird, wobei letztere verhindert, dass das Filter abklappt. In einer anderen Weiterbildung mag das Filter ausschliesslich durch magnetische Haltekräfte an der Türe gehalten werden.By using a magnetic holding force, the release of the filter from the door is much easier because the filter is manually solvable by overcoming the magnetic holding force from the door. The filter can be attacked at any point by the user. Also a replacement of the filter is designed simply because the filter must be guided only approximately to its operating position. The transfer to its final operating position can be due to the magnetic attraction without further manual intervention. This is especially true when the filter is inserted, for example between another filter and the door, which further filter is preferably connected via a folding mechanism such as a hinge with the door. Then the filter approaches by collapse of the other filter to its operating position, wherein also the transfer of the filter takes place in its final operating position by the magnetic attraction. The hinge of the further filter may serve as a support for the filter, so that the filter is held in this development in its operating position by the support and the magnetic holding force, the latter prevents the filter from collapsing. In another embodiment, the filter may be held exclusively by magnetic holding forces on the door.

Das oben bereits erwähnte weitere Filter ist bevorzugt dem Filter in Prozessluftstromrichtung vorgeschaltet, sodass in Betriebspositionen des weiteren Filters und des Filters zuerst das weitere Filter und dann das Filter durch den Prozessluftstrom aus dem Trocknungsraum durchströmt wird. Das weitere Filter kann ebenfalls durch eine magnetische Haltekraft an der Türe gehalten sein, bevorzugt zusammen mit einer weiteren Lagerung wie beispielsweise einem Scharnier, um das das weitere Filter von der Türe abklappbar ist durch Überwindung der magnetischen Haltekraft. Bevorzugt ist das weitere Filter aber nicht beliebig weit abklappbar. Ein Anschlag, oder ein ebenfalls zur Kategorie der Anschläge zählender Begrenzer in Form eines Halteseils zwischen Türe und weiterem Filter verhindert ein beliebig weites Abklappen des weiteren Filters. Mit einem solchen Mittel wird ein Klappwinkel zwischen der Betriebsposition des weiteren Filters und seiner aufgeklappten Position begrenzt, bevorzugt auf einen Winkel kleiner 60 Grad, und in einer weiteren Ausgestaltung auf einen Winkel kleiner 45 Grad. Dies hat den Vorteil, dass, wie oben angedeutet, ein einmal gelöstes Filter zwischen weiterem Filter und Türe eingelegt werden kann und dadurch zumindest grob in seiner Lage fixiert ist. Das Konstrukt aus weiterem Filter mit eingelegtem Filter kann dann zur Türe hin manuell zugeklappt werden, wobei das eingelegte Filter somit selbständig in seine Betriebsposition überführt wird.The above-mentioned further filter is preferably upstream of the filter in the process air flow direction, so that in operating positions of the further filter and the filter first the further filter and then the filter is flowed through by the process air flow from the drying space. The further filter can also be held by a magnetic holding force on the door, preferably together with another storage such as a hinge, by which the further filter can be folded down from the door by overcoming the magnetic holding force. Preferably, however, the additional filter can not be folded down as far as desired. A stop, or a likewise counting to the category of stops limiter in the form of a tether between door and further filter prevents any further folding of the other filter. With such a means, a folding angle between the operating position of the other filter and limited to its unfolded position, preferably to an angle less than 60 degrees, and in another embodiment to an angle less than 45 degrees. This has the advantage that, as indicated above, a once-released filter between other filter and door can be inserted and thereby at least roughly fixed in position. The construct of further filter with inserted filter can then be folded manually towards the door, whereby the inserted filter is thus transferred independently to its operating position.

Andererseits kann bei einer solchen Ausbildung das weitere Filter derart ausgebildet sein, dass es bei seiner Überführung aus der Betriebsposition in die aufgeklappte Position die Betriebsposition des Filters an der Türe nicht beeinflusst. Insofern weist das weitere Filter keine Mittel auf, die das Filter beim Aufklappen des weiteren Filters aus seiner Betriebsposition lösen, und beispielsweise mitnehmen. Damit verbleibt das Filter an der Türe und kann in dieser Position leicht manuell gereinigt werden. Es ist darauf hinzuweisen, dass bevorzugt ein Abklappen des weiteren Filters nur bei geöffneter Türe erfolgen kann.On the other hand, in such a design, the further filter may be designed such that it does not affect the operating position of the filter on the door when it is transferred from the operating position to the unfolded position. In this respect, the further filter has no means that solve the filter when unfolding the other filter from its operating position, and take, for example. This leaves the filter on the door and can be easily cleaned manually in this position. It should be noted that preferably a folding of the other filter can only be done with the door open.

Es sei ferner darauf hingewiesen, dass das weitere Filter auch als Bestandteil der Türe aufgefasst werden kann, da es beispielsweise über ein Scharnier mit der Türe in nicht lösbarer Weise verbunden ist. In diesem Sinne ist das weitere Filter als Klappdeckel ausgebildet, der zusammen mit der Türinnenwand einen Raum definiert, in dem das Filter angeordnet ist. Insofern kann das Filter über eine magnetische Haltekraft auch direkt an dem weiteren Filter angeordnet sein und von diesem gehalten werden. In dieser Weiterbildung würde bei aufgeklapptem weiterem Filter das eingelegte und an dem weiteren Filter gehaltene Filter mit abgeklappt werden.It should also be noted that the other filter can also be considered as part of the door, since it is connected, for example via a hinge with the door in a non-detachable manner. In this sense, the further filter is designed as a hinged lid, which defines together with the door inner wall a space in which the filter is arranged. In this respect, the filter can be arranged via a magnetic holding force directly to the other filter and held by this. In this development, the inserted and held on the other filter filter would be folded with unfolded further filter.

Vorzugsweise weist bei Vorhandensein des weiteren Filters selbiges eine grobmaschigere Struktur auf als das Filter. Das weitere Filter mag als durchlöcherte Plastikscheibe der Grobfilterung des Prozessluftstroms dienen, wohingegen das Filter feinmaschiger ausgebildet ist und damit auch Partikel und Flusen kleineren Durchmessers zurückgehalten werden.Preferably, in the presence of the further filter, the same has a coarser mesh structure than the filter. The other filter may be perforated Plastic disc of coarse filtration of the process air flow serve, whereas the filter is formed fine-meshed and thus also particles and fluff of smaller diameter are retained.

In einer bevorzugten Ausgestaltung weist das Filter ein ein Magnetfeld erzeugendes Element auf, beispielsweise in Form eines oder mehrerer Dauermagneten. Dieses Element wirkt zusammen mit einem in der Türe angeordneten magnetischen Element, beispielsweise einem ferromagnetischen Element, welches in der Betriebsposition des Filters dem das Magnetfeld erzeugende Element gegenübersteht. Dadurch ziehen sich die Elemente gegenseitig an und rufen die magnetische Haltekraft zum Halten des Filters an der Türe hervor.In a preferred embodiment, the filter has a magnetic field generating element, for example in the form of one or more permanent magnets. This element cooperates with a magnetic element arranged in the door, for example a ferromagnetic element, which in the operating position of the filter faces the magnetic field generating element. As a result, the elements attract each other and cause the magnetic holding force to hold the filter on the door.

Bevorzugt wirkt das das Magnetfeld erzeugende Element bei geschlossener Türe auch mit einem an einer Frontwand des Haushaltsgeräts angeordneten Magnetschalter zusammen. Die Kontakte eines solchen beispielsweise als Reed-Schalter ausgebildeten Magnetschalters werden dann durch das von dem Element erzeugten Magnetfeld zum Schliessen veranlasst. Ein Schliessen des Magnetschalters beispielsweise gibt dann einen Trocknungsbetrieb des Haushaltsgeräts frei. Der Trocknungsbetrieb umfasst insbesondere das bevorzugt gebläseunterstützte Führen des Prozessluftstroms durch den Trocknungsraum. Insofern wird der Trocknungsbetrieb nur freigegeben, wenn sowohl das Filter in seiner Betriebsposition an der Türe gehalten wird und gleichzeitig die Türe auch geschlossen ist. Fehlt einer dieser Voraussetzungen, wird der Trocknungsbetrieb nicht freigegeben sondern unterbunden, d.h. insbesondere das bevorzugt gebläseunterstützte Führen des Prozessluftstroms durch den Trocknungsraum wird unterbunden, da davon ausgegangen werden muss, dass ein solcher Prozessluftstrom ungefiltert bis zum Wärmetauscher gelangen und diesen verschmutzen kann. Der Trocknungsbetrieb wird also bevorzugt unterbunden, wenn die Beschickungstüre offen ist. Ist bei offener Türe das Filter nicht in seiner Betriebsposition vorhanden, so fehlt es bereits an dem Vorhandensein des das Magnetfeld erzeugenden Elements. Ist die Türe offen und das Filter in seiner Betriebsposition an der Türe gehalten, so ist das das Magnetfeld erzeugende Element infolge des geöffneten Zustands der Türe jedenfalls so weit von dem Magnetschalter an der Geräte-Frontwand entfernt, dass der Magnetschalter nicht geschaltet wird und deshalb eine Freigabe des Trocknungsbetriebs unterbleibt. Ist die Türe aber geschlossen und das Filter nicht eingesetzt, so fehlt es wiederum bereits an dem das Magnetfeld erzeugenden Element, das ja am Filter angeordnet ist. Nur wenn das Filter in seiner Betriebsposition an der Türe gehalten ist und damit das das Magnetfeld erzeugende Element vorhanden ist und wenn gleichzeitig die Türe die Beschickungsöffnung verschliesst und damit das das Magnetfeld erzeugende Element in eine Position gebracht ist, in der es auf den Magnetschalter einwirkt, dann kann der Magnetschalter ein Signal liefern. Erst dann wird der Trocknungsbetrieb freigegeben. Vorzugsweise wird dazu das Signal des Magnetschalters an eine Steuerung des Wäschetrockners geliefert, das je nach Signal den Trocknungsbetrieb freigibt oder unterbindet.Preferably, when the door is closed, the magnetic field generating element also cooperates with a magnetic switch arranged on a front wall of the household appliance. The contacts of such, for example, designed as a reed switch magnetic switch are then caused by the magnetic field generated by the element to close. Closing the magnetic switch, for example, then releases a drying operation of the household appliance. The drying operation comprises in particular the preferably fan assisted guiding of the process air flow through the drying space. In this respect, the drying operation is only released when both the filter is held in its operating position on the door and at the same time the door is closed. If one of these prerequisites is missing, the drying operation is not released but prevented, ie in particular the preferably fan assisted guiding of the process air flow through the drying space is prevented, since it must be assumed that such a process air flow can pass unfiltered to the heat exchanger and pollute it. The drying operation is therefore preferably prevented when the loading door is open. If the door is open, the filter is not in its operating position, it already lacks the presence of the magnetic field generating element. If the door is open and the filter is held in its operating position on the door, then the magnetic field generating element due to the open state of the door anyway so far away from the magnetic switch on the device front wall, that the magnetic switch is not switched and therefore a Release of the drying operation is omitted. However, if the door is closed and the filter is not inserted, then in turn it is already missing on the magnetic field generating element, which is indeed arranged on the filter. Only when the filter is held in its operating position on the door and thus the magnetic field generating element is present and at the same time the door closes the feed opening and thus the magnetic field generating element is brought into a position in which it acts on the magnetic switch, then the magnetic switch can provide a signal. Only then is the drying mode released. Preferably, the signal of the magnetic switch is supplied to a control of the tumble dryer, which releases or inhibits the drying operation depending on the signal.

Ist das zuvor beschriebene weitere Filter vorgesehen und wird dieses weitere Filter ebenfalls über eine magnetische Haltekraft in einer Betriebsposition an der Türe gehalten, so ist vorzugsweise ein für diese magnetische Haltekraft zumindest verantwortliches weiteres Element zum erzeugen eines Magnetfeldes derart angeordnet, dass es bei geschlossener Türe nicht den Magnetschalter an der Frontwand steuert.If the further filter described above is provided and this further filter is also held by a magnetic holding force in an operating position on the door, then preferably for this magnetic holding force at least responsible further element for generating a magnetic field is arranged such that it does not when the door is closed controls the magnetic switch on the front panel.

In einer weiteren vorteilhaften Weiterbildung der Erfindung ist das weitere Filter über ein Gelenk an der Türe gelagert, und über eine magnetische Haltekraft an dem Filter gehalten, falls vorhanden. Hierbei wird also das weitere Filter nur mittelbar über das eingelegte Filter an der Türinnenseite gehalten. Fehlt das Filter, so kann das weitere Filter nicht in seiner Betriebsposition an der Türe gehalten werden sondern bleibt in abgeklappter Position. Selbst wenn die Türe trotz abgeklapptem weiteren Filter geschlossen werden kann, so unterbleibt dennoch der Trocknungsbetrieb infolge des Fehlens des auf den Magnetschalter an der Frontwand einwirkenden Elements am Filter. Vorzugsweise sind hier die Positionen für die magnetischen Elemente an Filter und weiterem Filter so zueinander angeordnet, dass das weitere Filter nicht selbständig ohne Vorhandensein des Filters an der Türe gehalten werden kann, noch dass ein von dem weiteren Filter ausgehendes Magnetfeld auf den Magnetschalter an der Frontwand einwirken kann.In a further advantageous embodiment of the invention, the further filter is mounted on the door via a hinge, and held on the filter via a magnetic holding force, if present. Here, therefore, the other filter is held only indirectly on the inserted filter on the inside of the door. If the filter is missing, so the additional filter can not be kept in its operating position on the door but remains in the folded position. Even if the door can be closed despite folded another filter, so nevertheless the drying operation is omitted due to the absence of acting on the magnetic switch on the front wall element on the filter. Preferably, the positions for the magnetic elements on filter and further filter are arranged to each other here so that the additional filter can not be independently held without presence of the filter on the door, nor that emanating from the further filter magnetic field on the magnetic switch on the front wall can act.

In einer weiteren vorteilhaften Weiterbildung ist gegenüber der vorhergehenden Weiterbildung das weitere Filter ausschliesslich über eine magnetische Haltekraft am Filter gehalten. Ein Gelenk zwischen dem weiterem Filter und der Türe entfällt also. Damit kann auch das weitere Filter durch Überwinden der magnetischen Haltekraft leicht von der Türe gelöst werden und beispielsweise ausserhalb des Wäschetrockners gereinigt werden. Die magnetischen Haltekräfte und Steuerungen sind wie bei der vorhergehenden Weiterbildung implementiert.In a further advantageous development, the further filter is held exclusively by a magnetic holding force on the filter over the previous development. A joint between the other filter and the door is therefore eliminated. Thus, the other filter can be easily solved by overcoming the magnetic holding force from the door and, for example, be cleaned outside the tumble dryer. The magnetic holding forces and controls are implemented as in the previous development.

In einer anderen vorteilhaften Weiterbildung ist das weitere Filter nur über eine magnetische Haltekraft an der Türe gehalten, d.h. es ist wiederum kein Gelenk zwischen weiterem Filter und Türe vorgesehen.In another advantageous development, the further filter is held only by a magnetic holding force on the door, i. again there is no joint between further filter and door.

In einer weiteren vorteilhaften Weiterbildung ist die Türe in geschlossenem Zustand über eine magnetische Haltekraft an der Frontwand gehalten, wobei die Türe vorzugsweise zusätzlich wie bei herkömmlichen Wäschetrocknern über ein Scharnier oder Gelenk an der Frontwand gehalten wird. Durch Überwinden der magnetischen Haltekraft kann die Türe geöffnet werden. Vorzugsweise kann die das weitere Filter an der Türe haltende magnetische Haltekraft auch zum Halten der Türe an der Frontwand verwendet werden.In a further advantageous embodiment, the door is held in the closed state via a magnetic holding force on the front wall, wherein the door is preferably held in addition to the front wall as in conventional clothes dryers via a hinge or hinge. By overcoming the magnetic holding force, the door can be opened. Preferably, the magnetic holding force holding the further filter on the door can also be used to hold the door on the front wall.

Gemäss eines weiteren Aspekts der Erfindung wird ein Verfahren zum Betreiben eines solchen Haushaltsgeräts beansprucht, bei dem ein Trocknungsbetrieb des Haushaltsgeräts bei geschlossener Türe und bei gleichzeitig an der Türe gehaltenem Filter freigegeben wird, und bei dem der Trocknungsbetriebs bei nicht geschlossener Türe oder aber bei geschlossener Türe aber nicht an der Türe gehaltenem Filter unterbunden wird. Hierzu kann das Vorsehen von Elementen wie beispielsweise das Vorsehen eines ein Magnetfeld erzeugenden Elements zum Erzeugen der Haltekraft gleichzeitig als ein das Freigeben oder Unterbinden des Trocknungsbetriebs steuerndes Element wirken. Es ist darauf hinzuweisen, dass der Trocknungsbetrieb unterbunden wird sowohl, wenn die Türe nicht geschlossen ist, als auch wenn die Türe zwar geschlossen ist, aber das Filterelement nicht an der Türe angeordnet ist. Insofern ist auch bevorzugt, dass beide Szenarien erkannt werden und die Erkennung beider Szenarien in dem Haushaltsgerät implementiert ist.According to a further aspect of the invention, a method for operating such a household appliance is claimed in which a drying operation of the household appliance is released with the door closed and at the same time held on the door filter, and in the drying operation when the door is not closed or closed door but not held on the door filter is prevented. To this end, the provision of elements such as providing a magnetic field generating element for generating the holding force may simultaneously act as an element controlling the releasing or inhibiting the drying operation. It should be noted that the drying operation is inhibited both when the door is not closed and when the door is closed, but the filter element is not placed on the door. In this respect, it is also preferred that both scenarios are recognized and the detection of both scenarios is implemented in the household appliance.

Bevorzugte Weiterbildungen, die in Bezug zu das Haushaltsgerät offenbart sind, sollen auch als zu dem Verfahren zugehörig offenbart gelten, und umgekehrt.Preferred developments, which are disclosed in relation to the household appliance, are also to be considered to be disclosed as belonging to the method, and vice versa.

Detaillierte Beschreibung der FigurenDetailed description of the figures

Gleiche Elemente sind figurenübergreifend durch die gleichen Bezugszeichen gekennzeichnet.Identical elements are cross-figured by the same reference numerals.

FIG. 1 zeigt eine perspektivische Ansicht auf eine Innenseite einer Wäschetrocknertüre in einem ersten Zustand, gemäss einem Ausführungsbeispiel der Erfindung. An der Türe 1 ist über ein Scharnier 15 ein weiteres Filter 4 angeordnet. Dieses weitere Filter 4 ist in FIG. 1 in seinem maximal aufgeklappten Zustand gezeigt. Nicht ersichtliche Anschläge dienen zur Begrenzung eines Klappwinkels zwischen der Türe 1 und dem weiteren Filter 4. Das weitere Filter 4 ist aus Kunststoff hergestellt und weist einen Rahmen 42 und eine Filterfläche 41 auf, die durch eine mit Löchern versehene plane Kunststoffwand gebildet wird. Rahmen 42 und Filterfläche 41 sind einstückig hergestellt, beispielsweise im Spritzgussverfahren. FIG. 1 shows a perspective view of an inside of a clothes dryer door in a first state, according to an embodiment of the invention. At the door 1, a further filter 4 is arranged via a hinge 15. This further filter 4 is in FIG. 1 shown in its maximum unfolded state. Not obvious attacks serve to limit a folding angle between the door 1 and the other filter 4. The further filter 4 is made of plastic and has a frame 42 and a filter surface 41 which is formed by a perforated planar plastic wall. Frame 42 and filter surface 41 are made in one piece, for example by injection molding.

Die Türe 1 enthält einen Kragen 13, der in seinem Umfang etwa dem Umfang des weiteren Filters 4 entspricht, und der bei zugeklapptem weiteren Filter 4 mit dem Rahmen 42 des weiteren Filters 4 zusammenwirkt. Dazu weist der Kragen 13 eine erste Stirnseite 131 auf, an welcher Dichtlippen 133 angeordnet sind. Wird das weitere Filter 4 gegen die Türe 1 zugeklappt, so bewirken die Dichtlippen 133 und die Stirnseite 131 des Kragens eine dicht Verbindung zwischen dem Rahmen 42 des weiteren Filters 4 und der Türe 1. Die zugeklappte Position des weiteren Filters 4 wird auch als seine Betriebsposition bezeichnet, da in dieser Betriebsposition und bei geschlossener Türe 1 ein Prozessluftstrom durch das weitere Filter 4 in Richtung Türe 1 hindurch treten kann und durch das weitere Filter 4 gefiltert wird.The door 1 includes a collar 13, which corresponds in its circumference approximately to the circumference of the further filter 4, and which cooperates with folded further filter 4 with the frame 42 of the further filter 4. For this purpose, the collar 13 has a first end face 131, on which sealing lips 133 are arranged. If the additional filter 4 is closed against the door 1, then the sealing lips 133 and the end face 131 of the collar cause a tight connection between the frame 42 of the other filter 4 and the door 1. The closed position of the other filter 4 is also referred to as its operating position, since in this operating position and with the door 1 closed a process air flow through the other filter 4 in the direction of the door 1 therethrough can occur and is filtered by the other filter 4.

In seiner Betriebsposition wird das weitere Filter 4 durch eine magnetische Haltekraft gehalten, die erzeugt wird durch ein ein Magnetfeld erzeugendes weiteres Element 43, beispielsweise in Form eines Dauermagneten, in Verbindung mit einem an entsprechender Position am Kragen 13 angeordneten weiteren magnetischen Element 14, das mit dem weiteren Element 43 bei zugeklapptem weiteren Filter 4 zusammenwirkt. Im vorliegenden Zustand nach FIG. 1 ist jedoch die magnetische Haltekraft überwunden und das weitere Filter 13 in abgeklapptem Zustand.In its operating position, the further filter 4 is held by a magnetic holding force, which is generated by a further magnetic field generating element 43, for example in the form of a permanent magnet, in conjunction with a corresponding position on the collar 13 further magnetic element 14, with the further element 43 cooperates with another folded filter 4. In the present condition FIG. 1 However, the magnetic holding force is overcome and the other filter 13 in the folded state.

Ferner ist in FIG. 1 eine Griffmulde 12 im Kragen 13 ersichtlich, die ein manuelles Abklappen des weiteren Filters 4 durch den Benutzer erleichtern soll. Des Weiteren ist auch ein Rasthaken 11 ersichtlich, der die Türe 1 in geschlossener Position an einer Frontwand des Wäschetrockners zu halten vermag. Zudem ist eine zweite Stirnfläche 132 des Kragens 13 ersichtlich, die gegenüber der ersten Stirnfläche 131 etwas zurückversetzt ist. Ein Filter, das aber im vorliegenden Zustand nicht vorhanden ist - beispielsweise, weil es zur Reinigung entnommen wurde - liegt ansonsten in seinem Betriebszustand an der zweiten Stirnfläche 132 des Kragens 13 an. Dazu ist an dem Kragen 13 beispielsweise ein magnetisches Element 15 vorgesehen, das mit einem am Filter angeordneten ein Magnetfeld erzeugendes Element zusammenwirkt, um eine magnetische Haltekraft aufzubringen, die das Filter an der Türe 1 zu halten vermag.Furthermore, in FIG. 1 a recessed grip 12 in the collar 13 can be seen, which is intended to facilitate a manual folding of the further filter 4 by the user. Furthermore, a latching hook 11 can be seen, which is able to hold the door 1 in the closed position on a front wall of the tumble dryer. In addition, a second end face 132 of the collar 13 can be seen, which is slightly set back relative to the first end face 131. A filter, which is not present in the present state - for example, because it was removed for cleaning - is otherwise in its operating state at the second end face 132 of the collar 13 at. For this purpose, a magnetic element 15 is provided on the collar 13, for example, which cooperates with a filter arranged on the magnetic field generating element to apply a magnetic holding force, which is able to hold the filter on the door 1.

FIG. 2 zeigt nun einen weiteren Zustand einer solchen Türe 1 nach FIG. 1. Das Filter 3 mag nun gereinigt sein und wurde vom Benutzer des Wäschetrockners in das weitere Filter 4 eingelegt, d.h. zwischen dem weiteren Filter 4 und der Türe 1 eingelegt. Insofern ist in FIG. 2 ein Rahmen 31 des Filters 3 ersichtlich, welcher Rahmen 31 an seinem oberen Ende einen Fortsatz 311 aufweist. Der Fortsatz 311 enthält ein ein Magnetfeld erzeugendes Element 33, das beispielsweise in den Rahmen 31 eingebettet ist. In dem vorliegenden Zustand ist das Filter 3 nicht an dem weiteren Filter 4 gehalten. Das Element 33 und das magnetische Element 43 sind dazu zu weit voneinander beabstandet. FIG. 2 now shows a further state of such a door 1 after FIG. 1 , The filter 3 may now be cleaned and used by the user of the tumble dryer the further filter 4 inserted, that is inserted between the other filter 4 and the door 1. Insofar is in FIG. 2 a frame 31 of the filter 3 can be seen, which frame 31 has an extension 311 at its upper end. The extension 311 includes a magnetic field generating element 33, which is embedded in the frame 31, for example. In the present state, the filter 3 is not held on the further filter 4. The element 33 and the magnetic element 43 are too far apart from each other.

Ausgehend von FIG. 2 wird nun das weitere Filter 4 von dem Benutzer des Wäschetrockners manuell zugeklappt, d.h. auf die Türe 1 zu bewegt. Damit bewegt sich auch das eingelegte Filter 3 auf die Türe 1 zu. Auf dem letzten Abschnitt des Weges mag das manuelle Hinführen durch die bereits eintretende anziehende Wirkung zwischen weiterem magnetischen Element 14 und weiterem Element 43 unterstützt werden, oder auch zwischen Element 33 und magnetischem Element 13, sodass sich die Filter 4, beziehungsweise 3 und die Türe 1 bereits anziehen.Starting from FIG. 2 Now the other filter 4 is manually closed by the user of the tumble dryer, ie moved to the door 1 to. As a result, the inserted filter 3 also moves towards the door 1. On the last part of the way, the manual guiding may be assisted by the already occurring attractive effect between further magnetic element 14 and further element 43, or also between element 33 and magnetic element 13, so that the filters 4, 3 and the door 1, respectively already put on.

FIG. 3 zeigt daraufhin die Innenseite der Türe 1 in einem Zustand, bei dem das weitere Filter 4 und das Filter 3 jeweils ihre Betriebspositionen eingenommen haben und durch magnetische Haltekräfte an der Türe 1 gehalten werden. FIG. 3 then shows the inside of the door 1 in a state in which the other filter 4 and the filter 3 have each assumed their operating positions and are held by magnetic holding forces on the door 1.

In einem nächsten Schritt mag den Benutzer die Türe 1 und somit den Trocknungsraum 2 verschliessen und ein Trocknungsprogramm wählen. Da das Filter 3 in seiner Betriebsposition gehalten und die Türe 1 verschlossen ist, wird ein solcher Trocknungsbetrieb nicht unterbunden und die Trocknung der Wäsche im Trocknungsraum kann beginnen.In a next step, the user may close the door 1 and thus the drying room 2 and select a drying program. Since the filter 3 is held in its operating position and the door 1 is closed, such a drying operation is not inhibited and the drying of the laundry in the drying room can begin.

Nach dem Ende des Trocknungsprogramms mag die Türe entriegelt und durch den Benutzer geöffnet werden. Der Benutzer mag dann beispielsweise wieder die Notwendigkeit sehen, das Filter 3 zu reinigen. Dazu greift er in die Griffmulde 12 ein und klappt das weitere Filter 4 ab gegen die magnetische Haltekraft des weiteren magnetischen Elements 14 in Verbindung mit dem weiteren Element 43, bis das weitere Filter 4 von dem Anschlag in seiner Position der maximalen Auslenkung gehalten wird, siehe FIG. 4.After the end of the drying program, the door may be unlocked and opened by the user. For example, the user may again see the need to clean the filter 3. For this purpose, he engages in the recessed grip 12 and folds the other filter. 4 ab against the magnetic holding force of the further magnetic element 14 in conjunction with the further element 43 until the further filter 4 is held by the stopper in its position of maximum deflection, see FIG. 4 ,

Bei diesem Klappvorgang behält das Filter 3 seine Betriebsposition bei. Vorzugsweise enthält das weitere Filter 4 also keinen Mitnehmer für das Filter 3. In seiner Betriebsposition kann das Filter 3 nun auch ohne von der Türe 1 gelöst zu werden durch den Benutzer gereinigt werden. Abschliessend braucht der Benutzer nur noch das weitere Filter 4 gegen die Türe zu klappen.In this folding operation, the filter 3 maintains its operating position. Preferably, the further filter 4 thus contains no driver for the filter 3. In its operating position, the filter 3 can now be cleaned by the user without being released from the door 1. Finally, the user only needs to fold the additional filter 4 against the door.

FIG. 5 zeigt einen Wäschetrockner in perspektivischer Ansicht, gemäss einem Ausführungsbeispiel der Erfindung. Hier ist nun die Türe 1 in geöffnetem Zustand gezeigt, das weitere Filter 4 ist in seiner Betriebsposition an der Türe 1 gehalten, das nicht sichtbare Filter 3 ist zwischen dem weiteren Filter 4 und der Türe 1 ebenfalls in seiner Betriebsposition gehalten. FIG. 5 shows a clothes dryer in a perspective view, according to an embodiment of the invention. Here, the door 1 is now shown in the open state, the other filter 4 is held in its operating position on the door 1, the non-visible filter 3 is also held in its operating position between the other filter 4 and the door 1.

Eine Frontwand 5 des Wäschetrockners weist eine Öffnung zu einem als Trommel ausgebildeten Trocknungsraum 2 auf. Ein Türrahmen 53 der Frontwand 5 begrenzt die Öffnung. Dieser Türrahmen 53 weist ein drittes Filter 54 an seinem unteren Umfang auf. Bei geschlossener Türe 1 - ein Verschlusselement 51 hält die Türe 1 beispielsweise in geschlossenem Zustand - wird der das Filter 3 in der Türe 1 durchströmende Prozessluftstrom nach unten umgelenkt, tritt durch eine Öffnung im Kragen 13 der Türe 1 durch, tritt in die Öffnung im Türrahmen 53 der Frontwand 5 ein, um dort das dritte Filter 54 zu passieren.A front wall 5 of the tumble dryer has an opening to a drying chamber 2 designed as a drum. A door frame 53 of the front wall 5 limits the opening. This door frame 53 has a third filter 54 at its lower periphery. When the door is closed 1 - a closure member 51 holds the door 1, for example, in the closed state - the filter 3 in the door 1 flowing through the process air flow is deflected downward, passes through an opening in the collar 13 of the door 1, enters the opening in the door frame 53 of the front wall 5, there to pass the third filter 54.

Unterhalb einer Bedienleiste 55, oder aber in diese integriert, ist ein Magnetschalter 52 an der Frontwand 5 angeordnet. Dieser Magnetschalter 52 schliesst beispielsweise seine Kontakte unter dem Einfluss eines Magnetfeldes. Bei geschlossener Türe 1 und an der Türe 1 gehaltenem Filter 3 wirkt nun das von dem Element 33 erzeugte Magnetfeld - siehe Figuren 2 bis 4 - auf den Magnetschalter 52 ein und verursacht ein Schliessen seiner Kontakte und damit ein Signal, das von einer Steuerung beispielsweise in eine Freigabe für einen Trocknungsbetrieb des Wäschetrockners übersetzt wird. Für ein Durchführen des Trocknungsprogramms mag der Benutzer zusätzlich noch eine Wahltaste auf dem Bedienfeld 55 drücken. Der Magnetschalter 52 ist also vorzugsweise so an der Frontwand 5 angeordnet, dass er bei geschlossener Türe 1 und an der Türe 1 gehaltenem Filter 3 mit dessen Element 33 zusammenwirken kann.Below a control bar 55, or integrated into this, a magnetic switch 52 is disposed on the front wall 5. This magnetic switch 52 closes, for example, its contacts under the influence of a magnetic field. When the door 1 is closed and the filter 3 held on the door 1 now acts on the element 33 generated Magnetic field - see FIGS. 2 to 4 - On the magnetic switch 52 and causes a closure of its contacts and thus a signal that is translated by a controller, for example, in a release for a drying operation of the clothes dryer. For performing the drying program, the user may additionally press a selection key on the control panel 55. The magnetic switch 52 is thus preferably arranged on the front wall 5 so that it can interact with its element 33 with the door 1 closed and the door 1 held on the filter 3.
