Description

Die Erfindung betrifft ein Haushaltsgerät zur Pflege von Wäschestücken, mit einem Gehäuse, in welchem eine Wäschetrommel drehbar gelagert ist, und mit zumindest einer ringförmigen Unwuchtausgleichsvorrichtung zum Ausgleichen einer aufgrund von unsymmetrisch in der Wäschetrommel verteilter Wäschestücke hervorgerufenen Unwucht der sich drehenden Wäschetrommel, welche an der Wäschetrommel angeordnet ist.The invention relates to a household appliance for the care of items of laundry, with a housing in which a laundry drum is rotatably mounted, and with at least one annular unbalance compensation device for compensating a due to asymmetrically distributed in the laundry drum laundry items unbalance of the rotating laundry drum, which on the laundry drum is arranged.

Während eines Waschprozesses einer Waschmaschine kommt es bekanntlich zu einer zufälligen und unregelmäßigen Verteilung der Wäschestücke in der Wäschetrommel. Es resultieren Unwuchten, die relativ große mechanische Schwingungen der Wäschetrommel und damit auch große mechanische Belastungen des gesamten Haushaltsgeräts verursachen. Einerseits werden durch die resultierenden Schwingungen für den Benutzer unangenehme Geräusche erzeugt; andererseits kann dies auch zu einer mechanischen Beanspruchung des Bodenbelags führen, auf welchem das Haushaltsgerät aufgestellt ist.During a washing process of a washing machine, it is known that a random and irregular distribution of the laundry items in the laundry drum. This results in imbalances that cause relatively large mechanical vibrations of the laundry drum and thus large mechanical loads on the entire household appliance. On the one hand, unpleasant noises are generated by the resulting vibrations for the user; On the other hand, this can also lead to a mechanical stress on the flooring on which the household appliance is placed.

Um im Betrieb einer Waschmaschine die Schwingungen der Wäschetrommel zu verhindern oder zumindest stark zu reduzieren, wird im Stand der Technik bereits vorgeschlagen, eine ringförmige Unwuchtausgleichsvorrichtung - auch unter der Bezeichnung "Ball-Balancer" bekannt - an der Wäschetrommel zu befestigen. Eine derartige Unwuchtausgleichsvorrichtung weist ein ringförmiges, hohles Gehäuse auf, in welchem sich eine Ausgleichsmasse befindet, die beispielsweise in Form von mehreren kugelförmigen Ausgleichselementen bereitgestellt ist. Diese Ausgleichsmasse ist im Inneren des Gehäuses bewegbar gelagert und tendiert im Betrieb der Waschmaschine dazu, sich auf eine der Unwuchtmasse - bezüglich eines Durchmessers der Wäschetrommel - gegenüberliegende Seite zu verschieben, um somit ein Gegengewicht für die Unwuchtmasse und folglich insgesamt ein Gleichgewicht herzustellen.In order to prevent or at least greatly reduce the vibrations of the laundry drum during operation of a washing machine, it has already been proposed in the prior art to fasten an annular balancing device - also known as "ball balancer" - to the laundry drum. Such an imbalance compensation device has an annular, hollow housing, in which there is a balancing mass, which is provided for example in the form of a plurality of spherical compensating elements. This balancing mass is movably mounted in the interior of the housing and during operation of the washing machine tends to shift to one of the imbalance masses - with respect to a diameter of the laundry drum - opposite side, thus producing a counterweight for the imbalance mass and consequently an overall balance.

Es beschreibt beispielsweise die Druckschrift US 2011/0203325 A1 eine Lösung zur Befestigung einer Unwuchtausgleichsvorrichtung, bei welcher das Gehäuse der Unwuchtausgleichsvorrichtung an eine axiale Stirnwand der Wäschetrommel angespritzt wird.It describes, for example, the publication US 2011/0203325 A1 a solution for fixing an imbalance compensation device, wherein the housing of the Unbalance compensation device is molded onto an axial end wall of the laundry drum.

Es ist außerdem bereits Stand der Technik, die Unwuchtausgleichsvorrichtung mit Hilfe von Schrauben an der Wäschetrommel zu befestigen. In diesem Zusammenhang ist es beispielsweise bekannt, an einer axialen Seite der Unwuchtausgleichsvorrichtung Fortsätze mit radialen Bohrungen bzw. so genannte Schraubdome vorzusehen, welche jeweils zur Aufnahme einer Schraube ausgebildet sind. Durch derartige Schraubdome wird jedoch relativ viel Bauraum in axialer Richtung benötigt, wodurch in nachteiliger Weise das Nutzvolumen des Wäscheraums der Trommel insgesamt deutlich reduziert werden muss. An diesem Stand der Technik ist des Weiteren als nachteilig der Umstand anzusehen, dass zusätzliche Befestigungselemente in Form von Schrauben bereitgestellt werden müssen und außerdem aufwendige Schraubvorgänge erforderlich sind, die zu einer Verzögerung des Montageprozesses führen.It is also already prior art to attach the unbalance compensation device by means of screws to the laundry drum. In this connection, it is known, for example, to provide extensions with radial bores or so-called screw domes on one axial side of the unbalance compensation device, which are each designed to receive a screw. By such screw domes, however, a relatively large amount of space in the axial direction is required, which disadvantageously the useful volume of the wash chamber of the drum must be significantly reduced overall. Furthermore, the circumstance that additional fastening elements in the form of screws must be provided and also complicated screwing operations are required, which lead to a delay of the assembly process, is disadvantageous in this state of the art.

Eine Schraubverbindung zwischen einer Unwuchtausgleichsvorrichtung und einer Wäschetrommel wird beispielsweise in der EP 2 154 285 A1 vorgeschlagen. Alternativ ist allgemein auch ein Haken genannt, der als Halteelement für die Unwuchtausgleichsvorrichtung vorgesehen sein kann, jedoch keine weitere Information gegeben, wie der Haken geformt sein könnte und wo er genau befestigt ist.A screw connection between an imbalance compensation device and a laundry drum is, for example, in the EP 2 154 285 A1 proposed. Alternatively, a hook is generally also called, which can be provided as a holding element for the imbalance compensation device, but given no further information on how the hook could be formed and where it is accurately fixed.

Des Weiteren beschreibt die KR 10 2008 037 420 A eine Anordnung, bei welcher eine Unwuchtausgleichsvorrichtung über eine Rastverbindung an einer Wäschetrommel festgelegt ist. Bei der Ausführungsform gemäß Fig. 1 von diesem Dokument sind an einem radialen Außenumfang eines Gehäuses der Unwuchtausgleichsvorrichtung Rastelemente ausgebildet, welche in korrespondierenden Rastöffnungen der Wäschetrommel eingerastet sind. Die Rastelemente liegen dabei an einer die jeweilige Rastöffnung begrenzenden Kante axial an, sodass eine formschlüssige Verbindung in axialer Richtung gebildet ist. Eine derartige Rastverbindung hat insbesondere den Nachteil, dass es zu einem Lösen der Rastverbindung kommen kann. Im Betrieb der Waschmaschine können nämlich radiale Verformungen der Wäschetrommel - insbesondere eine Ovalisierung - auftreten, was zu einer radialen Verschiebung zwischen dem Mantel der Wäschetrommel einerseits und dem Gehäuse der Unwuchtausgleichsvorrichtung andererseits führen kann. Kommt es zu einer derartigen Verschiebung, so können sich die Rastelemente der Unwuchtausgleichsvorrichtung von den jeweiligen Rastöffnungen lösen, und es kann insgesamt zu einem Herausfallen der Unwuchtausgleichsvorrichtung aus der axialen Vertiefung der Wäschetrommel kommen.Furthermore, the describes KR 10 2008 037 420 A an arrangement in which an imbalance compensation device is fixed via a latching connection to a laundry drum. In the embodiment according to Fig. 1 Of this document, locking elements are formed on a radial outer circumference of a housing of the unbalance compensation device, which are engaged in corresponding latching openings of the laundry drum. The latching elements lie axially against an edge delimiting the respective latch opening, so that a positive connection is formed in the axial direction. Such a latching connection has in particular the disadvantage that it may come to a release of the latching connection. In the operation of the washing machine namely radial deformations of the laundry drum - in particular an ovalization - occur, which can lead to a radial displacement between the jacket of the laundry drum on the one hand and the housing of the balancing device on the other. Does it come to such a Displacement, so the locking elements of the imbalance compensation device can be released from the respective detent openings, and it can come to a total fall out of the imbalance compensation device from the axial recess of the laundry drum.

Aus der DE 10 2013 221 292 A1 und der DE 10 2013 221 293 A1 sind weitere Ausführungen für Befestigungen von Unwuchtausgleichsvorrichtungen an der Wäschetrommel bekannt.From the DE 10 2013 221 292 A1 and the DE 10 2013 221 293 A1 Further versions for attachments of imbalance compensation devices on the laundry drum are known.

Ferner ist aus DE 10 2009 021 327 A1 eine Waschmaschine mit einer an einer Wäschetrommel befestigten Unwuchtausgleichsvorrichtung bekannt, welche zumindest einen an der Unwuchtausgleichsvorrichtung angeordneten Haken mit einer schrägen Seite aufweist, wobei in einem montierten Endzustand der Haken in radialer Richtung in eine Aussparung einer Wand der Wäschetrommel nach außen hin eingeführt ist.Furthermore, it is off DE 10 2009 021 327 A1 a washing machine with an attached to a laundry drum balancing device is known, which has at least one arranged on the balancing device hooks with an oblique side, wherein in an assembled end state, the hook is inserted in the radial direction in a recess of a wall of the laundry drum to the outside.

Es ist Aufgabe der Erfindung, ein Haushaltsgerät zur Pflege von Wäschestücken zu schaffen, bei welchem eine ringförmige Unwuchtausgleichsvorrichtung verbessert befestigt ist.It is an object of the invention to provide a household appliance for the care of laundry, in which an annular balancing device is attached improved.

Diese Aufgabe wird erfindungsgemäß durch ein Haushaltsgerät mit den Merkmalen des Anspruchs 1 gelöst.This object is achieved by a household appliance with the features of claim 1.

Ein erfindungsgemäßes Haushaltsgerät zur Pflege von Wäschestücken umfasst ein Gehäuse, in welchem eine Wäschetrommel drehbar gelagert ist. Das Haushaltsgerät umfasst darüber hinaus zumindest eine ringförmige Unwuchtausgleichsvorrichtung zum Ausgleichen einer aufgrund von unsymmetrisch in der Wechseltrommel verteilter Wäschestücke hervorgerufenen Unwucht bei sich drehender Wäschetrommel, und diese ringförmige Unwuchtausgleichsvorrichtung ist an der Wäschetrommel angeordnet.An inventive household appliance for the care of laundry comprises a housing in which a laundry drum is rotatably mounted. The domestic appliance further comprises at least one annular unbalance compensating device for compensating an unbalance caused by laundry items distributed asymmetrically in the interchangeable drum when the laundry drum is rotating, and this annular unbalance compensating device is arranged on the laundry drum.

Ein wesentlicher Gedanke der Erfindung ist darin zu sehen, dass das zumindest eine Halteelement an der Unwuchtausgleichsvorrichtung befestigt ist und einen bezüglich einer Längsachse der Wäschetrommel radial nach außen orientierten und rampenförmigen Federbügel aufweist. Dieser Federbügel ist im montierten Endzustand des Halteelements und somit auch der Unwuchtausgleichsvorrichtung in radialer Richtung zu dieser Längsachse der Wäschetrommel betrachtet in eine Aussparung in einer Wand der Wäschetrommel nach außen hin eingeschnappt. Durch diese Ausgestaltung ist es ermöglicht, dass die Unwuchtausgleichsvorrichtung einfach und somit auch montagefreundlich befestigt werden kann und dennoch stabil positioniert ist. Durch die geometrische Ausgestaltung des Halteelements und ihre positionelle Anordnung wird die Unwuchtausgleichsvorrichtung in radialer Richtung in gewissem Maße auch federnd gelagert. Dadurch können im Betrieb des Haushaltsgeräts und somit bei sich drehender Wäschetrommel auch bei noch verbleibenden jedoch sehr geringen Unwuchten unerwünschte lokale und große Radialkräfte zwischen der Unwuchtausgleichsvorrichtung und der Wäschetrommel vermieden werden bzw. durch radiale Relativbewegung gut aufgenommen werden und abgebaut werden.An essential idea of the invention is to be seen in that the at least one retaining element is attached to the imbalance compensation device and has a relative to a longitudinal axis of the laundry drum radially outwardly oriented and ramped spring clip. This spring clip is viewed in the mounted end state of the holding element and thus also the imbalance compensation device in the radial direction to this longitudinal axis of the laundry drum in a recess in a wall of the Wash drum snapped outwards. With this configuration, it is possible that the imbalance compensation device can be easily and thus also easy to install and yet is stably positioned. Due to the geometric configuration of the retaining element and its positional arrangement, the unbalance compensation device is also mounted resiliently in the radial direction to some extent. As a result, unwanted local and large radial forces between the imbalance compensation device and the laundry drum can be avoided during operation of the household appliance and thus with rotating laundry drum even with remaining but very small imbalances or be well received by radial relative movement and dismantled.

Ferner ist vorgesehen, dass der Federbügel ein freikragendes Ende aufweist, welches eine Zunge umfasst, die im montierten Zustand des Halteelements an einer der Unwuchtausgleichsvorrichtung zugewandten Innenseite eines die Aussparung begrenzenden Wandbereichs der Wand in radialer Richtung bezüglich einer Längsachse der Wäschetrommel betrachtet nach außen vorgespannt anliegt. Dies ist eine besonders vorteilhafte Ausführung, da somit auch eine in gewisser Weise federnde Lagerung der Unwuchtausgleichsvorrichtung in radialer Richtung ermöglicht ist. Im montierten Zustand drückt somit dieser Federbügel nach außen gegen die Wand und insbesondere den Wandbereich. Einerseits erstreckt sich ein Höcker bzw. Übergang zwischen einer Anlaufschräge und einer Rampenwand dieses rampenartigen Federbügels durch die Aussparung hindurch, andererseits liegt diese Zunge innenseitig an diesem Wandbereich an. Durch die spezifische Geometrie des rampenförmigen Federbügels ist dieser in sich sehr stabil und somit auch verwindungssteif, so dass gerade an diesem freikragenden Ende auch dann bei hoher Belastung im Betrieb des Haushaltsgeräts keine unerwünschten Verformungen, insbesondere plastische Verformungen, auftreten, während andererseits die radial nach außen wirkende Vorspannkraft des Federbügels aufrechterhalten ist.It is further provided that the spring clip has a freely projecting end, which comprises a tongue, which in the assembled state of the holding element on one of the unbalance compensation device facing inside of a recess bounding wall portion of the wall in the radial direction with respect to a longitudinal axis of the laundry drum is biased outwardly biased. This is a particularly advantageous embodiment, since thus also a somewhat resilient mounting of the imbalance compensation device in the radial direction is made possible. In the assembled state thus this spring clip pushes outwards against the wall and in particular the wall area. On the one hand, a hump or transition between a run-up slope and a ramp wall of this ramp-like spring clip extends through the recess, on the other hand, this tongue lies on the inside of this wall area. Due to the specific geometry of the ramp-shaped spring clip this is very stable and thus also torsionally rigid, so that even at high cantilever end even at high load during operation of the household appliance no undesirable deformations, in particular plastic deformations occur, while on the other hand, the radially outward acting biasing force of the spring clip is maintained.

Unter einer Unwuchtausgleichsvorrichtung wird vorliegend eine Vorrichtung verstanden, welche zum Ausgleich und somit zur Verhinderung von Unwuchten der Wäschetrommel ausgebildet ist. Die Unwuchtausgleichsvorrichtung kann eine bewegbar in dem Gehäuse angeordnete Ausgleichsmasse - beispielsweise in Form von mehreren kugelförmigen Elementen - aufweisen Eine derartige Unwuchtausgleichsvorrichtung kann auch als "Ball-Balancer" bezeichnet werden.Under an imbalance compensation device is understood in the present case a device which is designed to compensate and thus to prevent imbalances of the laundry drum. The unbalance compensation device can be a compensating mass arranged movably in the housing - for example in the form of a plurality of spherical ones Elements - having Such an imbalance compensation device can also be referred to as a "ball balancer".

Insbesondere ist vorgesehen, dass das Halteelement als mehrfach gebogener, einstückiger Streifen ausgebildet ist. Dadurch ist das Halteelement insbesondere in azimutaler Richtung um die Langsachse sehr kompakt aufgebaut Darüber hinaus wird durch die mehrfache Biegung auch die Stabilität des Halteelements in sich selbst erhöht, gerade in Richtung der Längsachse des Halteelements betrachtet.In particular, it is provided that the holding element is designed as a multiply bent, one-piece strip. As a result, the retaining element is constructed very compactly, in particular in the azimuthal direction about the longitudinal axis. Moreover, the multiple bending also increases the stability of the retaining element in itself, viewed in the direction of the longitudinal axis of the retaining element.

Vorzugsweise ist vorgesehen, dass das Halteelement einen Umgriffsbereich aufweist. Dieser Umgriffsbereich umgreift einen Koppelsteg. Der Koppelsteg ist an einem Ausgleichselemente aufnehmenden Gehäuse der Unwuchtausgleichsvorrichtung integriert und somit einstückig ausgebildet. Dieser Umgriffsbereich des Halteelements umgreift diesen Koppelsteg an drei Seiten und zwar derart, dass er an diesen drei Seiten anliegend angeordnet ist. Dadurch kann eine sehr stabile Befestigung des Halteelements an dem Gehäuse der Unwuchtausgleichsvorrichtung erreicht werden. Durch Integration des Koppelstegs ist dieser somit auch sehr positionsstabil angeordnet und muss nicht zusätzlich durch Montageaufwand an dem Gehäuse befestigt werden. Der Koppelsteg kann daher auch entsprechende Kräfte aufnehmen.It is preferably provided that the holding element has a Umgriffsbereich. This Umgriffsbereich surrounds a coupling bridge. The coupling web is integrated on a compensating elements receiving housing of the balancing device and thus integrally formed. This wraparound region of the retaining element engages around this coupling web on three sides in such a way that it is disposed adjacent to these three sides. As a result, a very stable attachment of the retaining element to the housing of the imbalance compensation device can be achieved. By integration of the coupling web this is thus also arranged very stable position and does not need to be additionally attached by mounting effort on the housing. The coupling bridge can therefore also absorb corresponding forces.

Insbesondere ist vorgesehen, dass der Koppelsteg an einer Gehäusewand des Gehäuses angeordnet ist die insbesondere eine radial äußere Wand des Gehäuses ist. Diese Gehäusewand ist einem dazu radial weiter außen liegenden Wandbereich der Wand der Wäschetrommel zugewandt, wobei sich die Aussparung in dem Wandbereich ausbildet. Der Koppelsteg erstreckt sich von der Gehäusewand in Richtung des Wandbereichs radial nach außen. Dadurch ist die örtliche Positionierung des Halteelements begünstigt und liegt in einem Zwischenraum zwischen dieser Wand der Wäschetrommel und dem Gehäuse der Unwuchtausgleichsvorrichtung auf diesem Umgriffsbereich.In particular, it is provided that the coupling web is arranged on a housing wall of the housing which is in particular a radially outer wall of the housing. This housing wall faces a wall region of the wall of the laundry drum lying radially further outward, the recess forming in the wall region. The coupling web extends from the housing wall in the direction of the wall region radially outward. As a result, the local positioning of the holding element is favored and lies in a space between this wall of the laundry drum and the housing of the imbalance compensation device on this Umgriffsbereich.

Das Halteelement ist daher mit diesem Umgriffsbereich in einem ohnehin vorhandenen Zwischenraum zwischen dem Gehäuse der Unwuchtausgleichsvorrichtung und der Wand der Wäschetrommel positioniert. Darüber hinaus ist durch diese örtliche Anordnung das Halteelement möglichst kurz, da auch dann die Aussparung in unmittelbarer Näher zu diesem Koppelsteg ausgebildet ist.The retaining element is therefore positioned with this Umgriffsbereich in an already existing gap between the housing of the balancing device and the wall of the laundry drum. In addition, the holding element is as short as possible by this local arrangement, since even then the recess is formed in the immediate vicinity of this coupling web.

Vorzugsweise ist vorgesehen, dass der Koppelsteg einen Hinterschnitt aufweist, in dem der Umgriffsbereich mit einer muldenförmigen bzw. höckerartigen Eingriffsnase eingreift. Dieser Hinterschnitt ist insbesondere an einer einer Rückwand der Wäschetrommel zugewandten Rückseite des Gehäuses der Unwuchtausgleichsvorrichtung ausgebildet. Zusätzlich zu dem dreiseitigen Umgreifen des Koppelstegs durch den Umgriffsbereich des Halteelements wird durch diese vorteilhafte Ausführung die mechanische Befestigung und die stabile Positionierung des Halteelements an dem Gehäuse verbessert. Die Position des Hinterschnitts weist darüber hinaus den Vorteil auf, dass aufgrund des dreiseitigen Umgriffs und dem sich von dem Umgriffsbereich wegerstreckenden Federbügel dann entsprechende auftretende Hebelkräfte verbessert aufgenommen werden können. Wird der Federbügel in radialer Richtung mit Kraft beaufschlagt, wird dies auch auf den Umgriffsbereich übertragen. Die örtliche Position des Hinterschnitts und auch der Eingriffsnase ist an einer dem Übergang zwischen dem Umgriffsbereich und dem Federbügel abgewandten Seite des Umgriffsbereichs ausgebildet. Der Übergang zwischen dem Umgriffsbereich und dem Federbügel liegt daher an einer Seite des Koppelstegs an, die derjenigen Seite gegenüberliegt, an welcher der Hinterschnitt ausgebildet ist. Dadurch erfolgt das durch eine Hebelwirkung erzeugte Abstützen des Übergangs zwischen dem Umgriffsbereich und dem Federbügel an einer anderen Seite des Koppelstegs, als der Hinterschnitt ausgebildet ist. Die dabei entstehenden Kräfte, die bei dem radialen Federn des Federbügels auftreten, können durch dieses Konzept und die Kopplung dieses spezifisch geformten Umgriffsbereichs mit dem Koppelsteg verbessert aufgenommen werden.It is preferably provided that the coupling web has an undercut, in which engages the Umgriffsbereich with a trough-shaped or hump-like engagement nose. This undercut is formed in particular on a rear wall of the laundry drum facing the rear side of the housing of the imbalance compensation device. In addition to the three-sided embrace of the coupling web by the Umgriffsbereich the holding element is improved by this advantageous embodiment, the mechanical attachment and the stable positioning of the retaining element on the housing. The position of the undercut further has the advantage that due to the three-sided gripping and the wegerstrecking of the Umgriffsbereich spring clip then corresponding occurring leverage forces can be improved recorded. If the spring clip is acted upon in the radial direction with force, this is also transmitted to the Umgriffsbereich. The local position of the undercut and also of the engagement lug is formed on a side of the wrap-around region facing away from the transition between the wrap-around region and the spring clip. The transition between the Umgriffsbereich and the spring clip is therefore on a side of the coupling web, which is opposite to the side on which the undercut is formed. As a result, the support produced by a lever action of the transition between the Umgriffsbereich and the spring clip on another side of the coupling web, as the undercut is formed. The resulting forces that occur in the radial springs of the spring clip can be accommodated improved by this concept and the coupling of this specifically shaped Umgriffsbereichs with the coupling web.

In vorteilhafter Weise ist vorgesehen, dass eine Mehrzahl von separaten Halteelementen an der Unwuchtausgleichsvorrichtung angeordnet ist. Die entsprechenden Vorteile werden dadurch nochmals verbessert, was insbesondere bezüglich der Montagefreundlichkeit und der verbesserten Lagerung zutrifft.It is advantageously provided that a plurality of separate holding elements is arranged on the imbalance compensation device. The corresponding advantages are thereby further improved, which is particularly true in terms of ease of installation and improved storage.

Insbesondere ist vorgesehen, dass zumindest drei derartige separate Halteelemente ausgebildet sind, die in Umlaufrichtung um eine Längsachse der Wäschetrommel äquidistant zueinander angeordnet sind. Dadurch lässt sich eine azimutal symmetrische Lagerung der Unwuchtausgleichsvorrichtung erzielen, die an mehreren Stellen durch eine radial nach außen wirkende Vorspannung generiert ist und durch die Federbügel in radialer Richtung und somit senkrecht zur Längsachse eine gewisse Bewegungsfreiheit zulässt. Andererseits ist durch diese Mehrzahl der Halteelemente, die dann sternförmig von der Längsachse nach außen wirkende Federkräfte erzeugen, eine sehr zentrierte Lagerung der Unwuchtausgleichsvorrichtung ermöglicht.In particular, it is provided that at least three such separate holding elements are formed, which are arranged in the direction of rotation about a longitudinal axis of the laundry drum equidistant from each other. As a result, an azimuthally symmetrical mounting of the imbalance compensation device can be achieved, which is generated at several points by a radially outwardly acting bias and allows by the spring clip in the radial direction and thus perpendicular to the longitudinal axis a certain freedom of movement. On the other hand, a very centered mounting of the imbalance compensation device is made possible by this plurality of holding elements, which then generate radially outward spring forces from the longitudinal axis.

Vorzugsweise ist vorgesehen, dass die Wand der Wäschetrommel eine Mantelwand ist, in welcher diese Aussparung für ein Halteelement ausgebildet ist.It is preferably provided that the wall of the laundry drum is a jacket wall, in which this recess is designed for a holding element.

Des Weiteren betrifft die Erfindung auch ein Verfahren zum Befestigen einer Unwuchtausgleichsvorrichtung an einer Wäschetrommel eines Haushaltsgeräts zur Pflege von Wäschestücken. Bei dem Verfahren wird zumindest ein Halteelement an der Unwuchtausgleichsvorrichtung befestigt, bevor die Unwuchtausgleichsvorrichtung an der Wäschetrommel montiert wird. Ein derartiges Zwischenmontagemodul, welches die Unwuchtausgleichsvorrichtung und das daran befestigte zumindest eine Halteelement umfasst, wird dann an der Wäschetrommel befestigt. Dazu wird bezüglich einer Längsachse der Wäschetrommel radial nach außen orientierter und rampenförmiger Federbügel des Halteelements in radialer Richtung zu dieser Längsachse betrachtet in eine Aussparung in einer Wand der Wäschetrommel nach außen hin eingeschnappt.Furthermore, the invention also relates to a method for attaching an imbalance compensation device to a laundry drum of a household appliance for the care of laundry items. In the method, at least one retaining element is attached to the unbalance compensation device before the unbalance compensation device is mounted on the laundry drum. Such an intermediate assembly module, which comprises the imbalance compensation device and the at least one retaining element attached thereto, is then fastened to the laundry drum. For this purpose, with respect to a longitudinal axis of the laundry drum radially outwardly oriented and ramped spring clip of the retaining element in the radial direction to this longitudinal axis considered snapped into a recess in a wall of the laundry drum to the outside.

Der rampenförmige bzw. schanzenförmige Federbügel wird daher mit seiner längeren Anlaufschräge der Rampenform in axialer Richtung der Längsachse in eine Aufnahme der Wäschetrommel eingeschoben. Dabei wird der Federbügel radial nach innen gedrückt, solange er an einer Innenseite des Wandbereichs der Wand der Wäschetrommel in axialer Richtung entlanggeschoben wird. Sobald ein Übergang zwischen dieser Anlaufschräge und einer an die Anlaufschräge mündenden Rampenwand des Federbügels durch die Vorspannung beim Erreichen der Aussparung radial nach außen in die Aussparung einschnappt, wird dann die montierte Endposition erreicht. Die Zunge, die an die Rampenwand mündet, insbesondere an einem dem Übergang zwischen der Rampenwand und der Anlaufschräge gegenüberliegenden Ende der Rampenwand mündet, legt sich dann bei diesem Hineinschnappen des Übergangs in die Aussparung mit seiner Außenseite an die Innenseite des Wandbereichs an. Dadurch ist auch ein unerwünschtes weites radial Nachaußenschnappen des Federbügels verhindert und die gewünschte radiale Vorspannkraft dieses Federbügels in dem montierten Endzustand aufrechterhalten.The ramp-shaped or ski-shaped spring clip is therefore inserted with its longer run-up slope of the ramp shape in the axial direction of the longitudinal axis in a recording of the laundry drum. In this case, the spring clip is pressed radially inwardly, as long as it is pushed along an inner side of the wall portion of the wall of the laundry drum in the axial direction. As soon as a transition between this run-on slope and a ramp wall of the spring clip which opens out onto the run-up slope snaps radially outwards into the recess through the prestressing when the recess is reached, the assembled end position is then reached. The tongue, which opens to the ramp wall, in particular opens at an opposite end of the transition between the ramp wall and the run-up slope of the ramp wall, then puts in this Eininschnappen the transition into the recess with its outside to the inside of the wall portion. As a result, an undesirable wide radially Nachaußenschnappen the spring clip is prevented and maintained the desired radial biasing force of this spring clip in the assembled final state.

In Fig. 1 ist in einer vereinfachten Frontansicht ein Haushaltsgerät 1 zur Pflege von Wäschestücken, welches beispielsweise eine Waschmaschine oder ein Waschtrockner sein kann, dargestellt. Das Haushaltsgerät 1 umfasst ein Gehäuse 2, in welchem eine Wäschetrommel 3 drehbar gelagert ist. Eine Drehachse A (Fig. 2) ist bei dieser Ausführung in der Darstellung in Fig. 1 senkrecht zur Figurenebene orientiert. Das Haushaltsgerät 1 umfasst darüber hinaus einen Laugenbehälter 4, der ebenfalls im Gehäuse 2 angeordnet ist und die Wäschetrommel 3 umgibt. Die Wäschetrommel 3 umfasst einen hohlzylinderförmigen Mantel und eine rückseitige Stirnwand und ist darüber hinaus frontseitig offen ausgebildet, sodass hier eine Beschickungsöffnung vorgesehen ist, über welche Wäschestücke in ein Inneres 5 der Wäschetrommel 3 eingebracht werden können. Die Beschickungsöffnung ist durch eine Tür 6 verschließbar, die bewegbar an dem Gehäuse 2 angeordnet ist.In Fig. 1 is a simplified front view of a household appliance 1 for the care of laundry, which may be, for example, a washing machine or a washer-dryer, shown. The household appliance 1 comprises a housing 2, in which a laundry drum 3 is rotatably mounted. A rotation axis A ( Fig. 2 ) is in this embodiment in the illustration in Fig. 1 oriented perpendicular to the plane of the figure. The household appliance 1 further comprises a tub 4, which is also arranged in the housing 2 and surrounds the laundry drum 3. The laundry drum 3 comprises a hollow cylindrical shell and a rear end wall and is also designed to be open at the front, so that here a feed opening is provided, via which laundry items can be introduced into an interior 5 of the laundry drum 3. The loading opening can be closed by a door 6, which is arranged movably on the housing 2.

In Fig. 2 ist eine Vertikalschnittdarstellung und somit eine Darstellung in der Schnittebene betreffend die y-z-Ebene gezeigt. Es ist die Wäschetrommel 3 mit dem hohlzylinderförmigen Mantel 7 dargestellt. Die Beschickungsöffnung 8 ist ebenso gezeigt. Die Wäschetrommel 3 weist benachbart zu einer Rückwand bzw. hinteren Stirnwand 9 einen Tragstern 10 auf, der mit der Wäschetrommel 3 fest verbunden ist. Der Tragstern 10 ist mit einer Welle 11 drehfest verbunden, wobei die Welle 11 über einen nicht gezeigten Antriebsmotor angetrieben wird, sodass die Drehung der Wäschetrommel 3 um die Drehachse A bewirkt wird.In Fig. 2 is a vertical sectional view and thus a representation in the sectional plane relating to the yz plane shown. It is the laundry drum 3 shown with the hollow cylindrical shell 7. The charging port 8 is also shown. The laundry drum 3 has, adjacent to a rear wall or rear end wall 9, a carrier star 10 which is fixedly connected to the laundry drum 3. The support star 10 is rotatably connected to a shaft 11, wherein the shaft 11 is driven by a drive motor, not shown, so that the rotation of the laundry drum 3 is effected about the axis of rotation A.

Im Betrieb des Haushaltsgeräts 1 und somit bei sich drehender Wäschetrommel 3 können sich eingebrachte Wäschestücke unsymmetrisch um die Achse A verteilt an einer Innenseite 12 des Mantels 7 anlegen, sodass bei Drehung der Wäschetrommel 3 eine Unwucht entstehen kann. Um dieser entgegenzuwirken beziehungsweise diese auszugleichen, umfasst das Haushaltsgerät 1 in der gezeigten Ausführung zwei Unwuchtausgleichsvorrichtungen 13 und 14. Wie darüber hinaus auch zu erkennen ist, ist an der Innenseite 12 eine Mehrzahl von Mitnehmern angeordnet, wobei in Fig. 2 lediglich der eine Mitnehmer 15 zu erkennen ist.During operation of the household appliance 1 and thus when the laundry drum 3 is rotating, introduced items of laundry can be distributed asymmetrically about the axis A on an inner side 12 of the jacket 7, so that an imbalance can occur when the laundry drum 3 rotates. In order to counteract or compensate for this, the domestic appliance 1 in the embodiment shown comprises two Unbalance compensation devices 13 and 14. As can also be seen, a plurality of drivers is arranged on the inner side 12, wherein in Fig. 2 only one driver 15 can be seen.

Die vordere Unwuchtausgleichsvorrichtung 13 ist in Richtung der Achse A betrachtet in einem vorderen Bereich 16 der Wäschetrommel 3 und insbesondere des Mantels 7 angeordnet, wohingegen die zweite Unwuchtausgleichsvorrichtung 14 in einem hinteren Bereich 17 angeordnet ist.The front unbalance compensation device 13 is viewed in the direction of the axis A in a front region 16 of the laundry drum 3 and in particular of the jacket 7, whereas the second unbalance compensation device 14 is arranged in a rear region 17.

Die erste Unwuchtausgleichsvorrichtung 13 ist als umlaufender geschlossener Ring ausgebildet, der rotationssymmetrisch um die Achse A orientiert ist. Die erste Unwuchtausgleichsvorrichtung 13 umfasst ein diesbezügliches ringförmiges Gehäuse 18, welches in der Schnittdarstellung in Fig. 2 erkennbar einen viereckigen Querschnitt aufweist. Dieses Gehäuse 18 hat einen Hohlraum 19, in dem ein oder mehrere Ausgleichselemente 20 relativ zum Gehäuse 18 bewegbar angeordnet sind. Im Ausführungsbeispiel kann ein Ausgleichselement 20 eine Kugel sein. Es kann auch zusätzlich oder anstatt dazu ein flüssiges Medium in dem Hohlraum 19 angeordnet sein.The first unbalance compensation device 13 is formed as a circumferential closed ring, which is rotationally symmetrical about the axis A oriented. The first unbalance compensation device 13 comprises a respective annular housing 18, which in the sectional view in Fig. 2 recognizable having a quadrangular cross-section. This housing 18 has a cavity 19 in which one or more compensation elements 20 are arranged to be movable relative to the housing 18. In the exemplary embodiment, a compensation element 20 may be a ball. It may also be arranged in addition to or instead of a liquid medium in the cavity 19.

Entsprechend ist auch die zweite Unwuchtausgleichsvorrichtung 14 ausgebildet, die ebenfalls ein entsprechend ausgebildetes Gehäuse 21, einen diesbezüglich innenliegenden Hohlraum 22 und ein, insbesondere vorzugsweise mehrere, relativ zum Gehäuse 21 in dem Hohlraum 22 bewegbare Ausgleichselemente 23 aufweist.Accordingly, the second unbalance compensation device 14 is also formed, which also has a correspondingly formed housing 21, a cavity 22 inwardly therefrom and, in particular, preferably a plurality of compensating elements 23 movable in the cavity 22 relative to the housing 21.

In Fig. 3 ist in einer detaillierteren Darstellung der in Fig. 2 gestrichelt umkreiste Bereich I gezeigt. In Fig. 3 ist jedoch im Unterschied zur Fig. 2 nicht eine Darstellung in negativer x-Richtung sondern in positiver x-Richtung gezeigt.In Fig. 3 is in a more detailed account of the in Fig. 2 dashed circled area I shown. In Fig. 3 However, unlike the Fig. 2 not a representation in the negative x-direction but shown in the positive x-direction.

Wie zu erkennen ist, weist die Wäschetrommel 3 einen Aufnahmebereich 24 auf, in den das Gehäuse 18 eingesetzt ist. Eine äußere Wand der Wäschetrommel 3, die den Mantel darstellt, weist an einem vorderen Bereich eine Falzung 26 auf. Dadurch ist der vordere Bereich der Wäschetrommel 3 und somit auch dieser Mantel 7 stabilisiert.As can be seen, the laundry drum 3 has a receiving region 24 into which the housing 18 is inserted. An outer wall of the laundry drum 3, which constitutes the jacket, has a fold 26 at a front region. As a result, the front region of the laundry drum 3 and thus also this jacket 7 is stabilized.

In diesem Mantel 7 ist ein Wandbereich 25 ausgebildet, in dem eine Aussparung 27 als durchgängiges Loch ausgebildet ist.In this jacket 7, a wall portion 25 is formed, in which a recess 27 is formed as a continuous hole.

Das Gehäuse 18 weist eine Gehäusewand 18a auf, die in radialer Richtung betrachtet diesem Wandbereich 25 zugewandt ist.The housing 18 has a housing wall 18a which, viewed in the radial direction, faces this wall region 25.

An die radial äußere Gehäusewand 18a ist ein Koppelsteg 28 integriert und somit einstückig ausgebildet. Der Koppelsteg 28 ist in einem in axialer Richtung und somit in Richtung der Längsachse A betrachtet hinteren Bereich der Gehäusewand 18a ausgebildet und erstreckt sich radial in Richtung des Wandbereichs 25.At the radially outer housing wall 18a, a coupling web 28 is integrated and thus formed in one piece. The coupling web 28 is formed in a rear region of the housing wall 18a viewed in the axial direction and thus in the direction of the longitudinal axis A and extends radially in the direction of the wall region 25.

Die Unwuchtausgleichsvorrichtung 13 ist mit einem Halteelement 29 verbunden und an der Wäschetrommel 3, insbesondere im Wandbereich 25, befestigt. Vorzugsweise sind mehrere derartige separate Halteelemente 29 vorgesehen, die in Umlaufrichtung um die Achse A äqudistant zueinander angeordnet sind. Vorzugsweise sind zumindest drei derartiger Halteelemente 29 vorgesehen.The imbalance compensation device 13 is connected to a holding element 29 and attached to the laundry drum 3, in particular in the wall region 25. Preferably, a plurality of such separate holding elements 29 are provided, which are arranged in the direction of rotation about the axis A equidistantly from each other. Preferably, at least three such retaining elements 29 are provided.

Das Halteelement 29 ist einstückig ausgebildet und als mehrfach gebogener Streifen gebildet. Das Halteelement 29 ist aus Metall ausgebildet.The holding element 29 is integrally formed and formed as a multi-curved strip. The holding element 29 is formed of metal.

Es umfasst einen Umgriffsbereich 30, der den Koppelsteg 28 an zumindest drei aneinander angrenzenden Koppelstegseiten 28a, 28b und 28c umgreift. Der Umgriffsbereich 30 ist somit als U-Form ausgebildet und liegt insbesondere vollflächig an diesen Seiten 28a bis 28c an.It comprises a wraparound region 30, which encompasses the coupling web 28 on at least three adjoining coupling web sides 28a, 28b and 28c. The Umgriffsbereich 30 is thus formed as a U-shape and lies in particular on the entire surface of these pages 28a to 28c.

Der Umgriffsbereich 30 umfasst eine höckerartige Eingriffsnase 31, die in eine Mulde bzw. Kerbe als Beispiel für eine Hinterschneidung 32 eingreift.The wrap-around region 30 comprises a hump-like engagement nose 31, which engages in a depression or notch as an example of an undercut 32.

Diese Hinterschneidung 32 ist in einer als Rückseite gebildeten Koppelstegseite 28b des Koppelstegs 28 ausgebildet. Diese Rückseite ist somit der Rückwand 9 zugewandt.This undercut 32 is formed in a coupling web side 28b of the coupling web 28 formed as a rear side. This rear side is thus facing the rear wall 9.

Das Halteelement 29 umfasst neben dem Umgriffsbereich 30 auch einen mit dem Umgriffsbereich 30 direkt verbundenen und daran anmündenden Federbügel 33. Der Federbügel 33 erstreckt sich ausgehend von einem Übergang bzw. einer Anmündung 34 an den Umgrifsbereich 30 schräg radial nach außen und ist freikragend.The retaining element 29 comprises not only the wraparound region 30 but also a spring clip 33 connected directly to the wraparound region 30 and touching it. The spring clip 33 extends obliquely radially outwardly starting from a transition or an attachment 34 to the surrounding region 30 and is free-standing.

Dieser Federbügel 33 umfasst in seiner rampenförmigen Gestalt eine schräge Anlaufwand bzw. Anlauframpe bzw. Anlaufschräge 35. Darüber hinaus umfasst dieser Federbügel 33 eine Rampenwand 36, die in einem Winkel kleiner 90° zur Anlaufschräge 35 orientiert ist und daran anmündet. Ein Übergang 37 zwischen der Anlaufschräge 35 und der Rampenwand 36 ist im montierten Endzustand, wie in Fig. 3 gezeigt ist, durch die Aussparung 27 hindurch erstreckend angeordnet.In addition, this spring clip 33 comprises a ramp wall 36, which is oriented at an angle of less than 90 ° to the run-on slope 35 and terminates thereon. A transition 37 between the run-up slope 35 and the ramp wall 36 is in the assembled final state, as in Fig. 3 is shown extending through the recess 27 extending therethrough.

Darüber hinaus umfasst der Federbügel 33 an seinem freikragenden Ende, welches dem Übergang 37 abgewandt ist, eine Zunge 38. Die Zunge 38 mündet an die Rampenwand 36 an einem dem Übergang 37 abgewandten Ende der Rampenwand 36.In addition, the spring clip 33 comprises at its free-projecting end, which faces away from the transition 37, a tongue 38. The tongue 38 opens onto the ramp wall 36 at an end of the ramp wall 36 facing away from the transition 37.

Wie zu erkennen ist, liegt im montierten Endzustand diese Zunge 38 an einer Innenseite 39 des Wandbereichs 25 an.As can be seen, lies in the final assembled state, this tongue 38 on an inner side 39 of the wall portion 25 at.

Im in Fig. 3 gezeigten Endzustand der Montage ist das in radialer Richtung bewegbare und federnde Element betreffend den Federbügel 33 in radialer Richtung nach außen vorgespannt gehalten. Dadurch wird eine radiale Lagerkraft erzeugt, die das Gehäuse 18 der Wäschetrommel 3 hält und insbesondere das Gehäuse 18 auch mittig zur Achse A hält.Im in Fig. 3 shown end state of the assembly is the radially movable and resilient element with respect to the spring clip 33 is biased outwardly biased in the radial direction. As a result, a radial bearing force is generated which holds the housing 18 of the laundry drum 3 and, in particular, holds the housing 18 also centered on the axis A.

In Fig. 4 ist in einer perspektivischen Darstellung eine Ausführung gezeigt, bei welcher im Unterschied zur Gestaltung in Fig. 3 insbesondere der Umgriffsbereich 30 des Federbügels 29 unterschiedlich zur Ausgestaltung in Fig. 3 ausgebildet ist. Hier umgreift der Umgriffsbereich 30 den Koppelsteg 28 sogar an vier Seiten. Es ist hier auch keine schnabelförmige und somit muldenartige Eingriffsnase 31 gebildet, sondern eine streifenförmige Endlasche des Umgriffsbereichs 30 erstreckt sich in eine Aussparung 40 hinein, so dass das Anliegen auch an der vierten Seite des Koppelstegs 28 ermöglicht ist.In Fig. 4 is shown in a perspective view of an embodiment in which, in contrast to the design in Fig. 3 In particular, the Umgriffsbereich 30 of the spring clip 29 different to the embodiment in Fig. 3 is trained. Here, the Umgriffsbereich 30 surrounds the coupling web 28 even on four sides. There is also no beak-shaped and thus trough-like engagement nose 31 formed, but a strip-shaped end tab of the Umgriffsbereichs 30 extends into a recess 40, so that the concern is also possible on the fourth side of the coupling web 28.

Im Hinblick auf die Montage ist vorgesehen, dass zunächst die Halteelemente 29 an dem Gehäuse 18 befestigt werden. Die Halteelemente 29 sind, wie ja bereits dargelegt, zu dem Gehäuse 18 separate Teile, die entsprechend daran befestigt werden.With regard to the assembly, it is provided that first the retaining elements 29 are fastened to the housing 18. The holding elements 29 are, as already stated, to the housing 18 separate parts, which are attached thereto accordingly.

Ein derartiges dann durch die Unwuchtausgleichsvorrichtung 13 und die Halteelemente 29 erzeugtes Zwischenmontagemodul wird dann insbesondere in axialer Richtung und somit entlang der Längsachse A von vorne kommend an der Wäschetrommel 3 befestigt und dazu das Gehäuse 18 in die Aufnahme 24 eingeschoben. Dabei werden dann, wenn die Federbügel 33 die Falzung 26 erreichen, diese Federbügel 33 radial nach innen gedrückt und gleiten dann insbesondere mit ihrem Übergang 37 entlang der Innenseite 39. Bei weiterem Entlangschieben in Richtung der Längsachse A schnappt dann der Übergang 37 bei Erreichen der Aussparung 27 radial nach außen in die Aussparung 27 hinein und im erreichten Endzustand liegt dann die Zunge 38 an der Innenseite 39 an, wie dies dann in Fig. 3 dargestellt ist.Such then then produced by the imbalance compensation device 13 and the holding elements 29 intermediate mounting module is then in particular in the axial direction and thus attached along the longitudinal axis A coming from the front of the laundry drum 3 and to the housing 18 is inserted into the receptacle 24. In this case, when the spring clip 33 reach the fold 26, this spring clip 33 is pressed radially inward and then slide in particular with its transition 37 along the inside 39. Upon further pushing along in the direction of the longitudinal axis A then snaps the transition 37 upon reaching the recess 27 radially outward into the recess 27 and in the final state reached then the tongue 38 is located on the inside 39, as then in Fig. 3 is shown.
