Die Erfindung betrifft eine frontbeschickbare Wäschebehandlungsmaschine mit einem Gehäuse, mit einer durch eine Tür verschließbaren im Wesentlichen kreisförmigen Gehäuseöffnung sowie einem in dem Gehäuse schwingbeweglich befestigten Laugenbehälter mit einer im Wesentlichen kreisförmigen Laugenbehälteröffnung und einer Dichtungsmanschette zur Verbindung zwischen Gehäuseöffnung und Laugenbehälteröffnung, die auf eine um die Gehäuseöffnung umlaufende Abkantung gestülpt und befestigt ist, und dieser überstülpte Bereich mit einem als Spannring ausgebildeten Spannelement zusammenwirkt.The invention relates to a front loadable laundry treatment machine with a housing, with a closable by a door substantially circular housing opening and a swing-mounted in the housing tub with a substantially circular lye container opening and a gasket for connection between the housing opening and lye container opening, the one to the housing opening circumferential fold is inverted and fastened, and this everted region cooperates with a clamping element designed as a clamping element.

So ist aus dem Stand der Technik gemäß der EP 1 321 558 A1 eine Dichtungsmanschette bekannt, die zur Abdichtung von Verbindungen in Haushaltsgeräten dient. Dabei erfolgt die Anbindung zwischen der vorderen Gehäusewand und dem Laugenbehälter. Die Dichtungsmanschette wird an umlaufenden Abkantungen, sowohl an der Gehäuseöffnung als auch an der Laugenbehälteröffnung befestigt, wobei gemäß dieser Ausführungsform auf die Verwendung eines Spannelementes, das diesen überstülpten Bereich zusätzlich stützt, verzichtet wird. Zudem weist die Dichtungsmanschette insbesondere zur Türöffnung hin eine Dichtlippe auf, die sich im geschlossenen Zustand der Tür an die Innenseite legt.So is from the prior art according to the EP 1 321 558 A1 a gasket known, which serves for the sealing of connections in household appliances. The connection between the front housing wall and the tub takes place. The gasket is attached to circumferential folds, both on the housing opening and the tub opening, according to this embodiment, on the use of a clamping element, which additionally supports this everted region, is omitted. In addition, the gasket, in particular to the door opening towards a sealing lip, which lays in the closed state of the door to the inside.

Eine weitere Ausführungsform des Standes der Technik ist in der DE 100 65 342 A1 offenbart, die an der Abkantung der Laugenbehälteröffnung mit einem Spannring versehen wird, der mit dem überstülpten Bereich zusammenwirkt. Bei diesen aus dem Stand der Technik bekannten Ausführungsformen wird es als nachteilig angesehen, dass ein separater Spannring zu montieren ist.Another embodiment of the prior art is in DE 100 65 342 A1 disclosed, which is provided at the fold of the tub opening with a clamping ring which cooperates with the everted portion. In these known from the prior art embodiments, it is considered disadvantageous that a separate clamping ring is to be mounted.

Der Erfindung liegt somit die Aufgabe zugrunde, eine verbesserte und einfache Befestigung für eine Dichtungsmanschette in einer frontbeschickbaren Wäschebehandlungsmaschine bereitzustellen.The invention is therefore based on the object to provide an improved and simple attachment for a gasket in a front-loading laundry treatment machine.

Erfindungsgemäß wird die Aufgabe mit einer frontbeschickbaren Wäschebehandlungsmaschine mit den Merkmalen des Anspruchs 1 und mit einer Dichtungsmanschette mit den Merkmalen des Anspruchs 8 gelöst. Ferner wird die Aufgabe mit dem Verfahren mit den Merkmalen des Anspruchs 9 gelöst. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung ergeben sich aus den abhängigen Ansprüchen 2 bis 7.According to the invention the object is achieved with a front loadable laundry treatment machine with the features of claim 1 and with a gasket with the features of claim 8. Furthermore, the object is achieved with the method having the features of claim 9. Advantageous embodiments and further developments of the invention will become apparent from the dependent claims 2 to 7.

Die mit der Erfindung erreichten Vorteile bestehen darin, dass die geformte Dichtungsmanschette bereits mit dem entsprechenden Klemmring ausgestattet ist, der nicht als gesondertes Teil zu montieren ist. Dieser kann durch einfaches Umklappen in seine Spannstellung verbracht werden, so dass der feste Sitz im Bereich der Abkantung und hier am überstülpten Bereich erzielt wird.The advantages achieved by the invention are that the molded gasket is already equipped with the corresponding clamping ring, not as a separate Part is to assemble. This can be moved by simply folding into its clamping position, so that the firm seat is achieved in the area of the fold and here at the recessed area.

Hierzu ist der Spannring einstückig am überstülpten Bereich der Dichtungsmanschette angeformt, wobei der angeformte Spannring hinsichtlich seines Umfangs ein geringes Untermaß aufweist, so dass in der geklappten Stützstellung eine durch Dehnung verursachte Zugkraft in dem Spannring wirkt, wodurch der überstülpte Bereich gegen die umlaufende Abkantung um die Gehäuseöffnung gepresst wird. Der Spannring stützt radial außenseitig den überstülpten Bereich und deckt diesen dadurch ab. Der Spannring als solches nimmt von seiner Querschnittserstreckung eine Tropfenform ein, die sich im geklappten bzw. gefalteten Zustand in die Hohlkehle des überstülpten Bereichs drückt. Dabei nimmt der Abstützring in seiner geklappten bzw. gefalteten Stützstellung eine zur Ebene der Gehäuseöffnung im Wesentlichen rechtwinklige Stützlage ein. Der Abstützring ist hierbei mit einem Filmscharnier hinter der Dichtlippe angeformt und ist nach der Montage der Dichtungsmanschette, also nach Einbringen des überstülpten Bereiches an der Abkantung, in die Stütz- und Spannlage klapp- bzw. faltbar. Befindet sich der Abstützring in seiner Spannstellung, so legt sich das angeformte Filmscharnier an bzw. über den oberen Bereich der Dichtungsmanschette spannend an.For this purpose, the clamping ring is integrally formed on the over-turned portion of the gasket, the molded clamping ring has a small undersize in terms of its circumference, so that in the folded support position caused by stretching tensile force acts in the clamping ring, whereby the invaginated area against the peripheral fold around the Housing opening is pressed. The clamping ring radially outwardly supports the over-turned area and thereby covers it. The clamping ring as such takes from its cross-sectional extension a teardrop shape, which presses in the folded or folded state in the groove of the everted region. In this case, the support ring takes in its folded or folded support position a to the plane of the housing opening substantially rectangular support position. The support ring is in this case formed with a film hinge behind the sealing lip and is after the installation of the sealing sleeve, so after inserting the everted portion of the fold, in the support and clamping position foldable or foldable. If the support ring is in its clamping position, the molded-on film hinge abuts or thrusts over the upper area of the gasket.

In einer zweckmäßigen Ausführung umfasst die Dichtungsmanschette im Bereich der Überstülpung eine umlaufende, zur Türöffnung gerichtete, einstückig angeformte Dichtlippe für die Tür. Damit wird kein zusätzliches Teil benötigt, wodurch die Montage vereinfacht und eine gute und dauerhafte Dichtigkeit erreicht wird.In an expedient embodiment, the sealing sleeve in the region of the protuberance comprises a circumferential, integrally formed sealing lip for the door directed towards the door opening. Thus, no additional part is needed, whereby the assembly is simplified and a good and lasting tightness is achieved.

Die Erfindung betrifft in gleicher Weise die Dichtungsmanschette für eine frontbeschickbare Wäschebehandlungsmaschine mit einem Gehäuse und einem Laugenbehälter, zur Verbindung zwischen einer Gehäuseöffnung zum Einbringen oder Herausnehmen von Wäsche und einer Laugenbehälteröffnung, die auf eine um die Gehäuseöffnung umlaufende Abkantung stülpbar ist und dieser überstülpte Bereich mit einem als Spannring ausgebildeten Spannelement zusammenwirkbar ist, wobei in diesem Bereich eine umlaufende zur Öffnung gerichtete Dichtlippe für die Tür angeordnet ist.The invention relates in the same way to the gasket for a front loadable laundry treatment machine with a housing and a tub, for connection between a housing opening for introducing or removing laundry and a tub opening, which can be slipped onto a circumferential edge around the housing opening and this everted area with a designed as a clamping ring clamping element is cooperable, wherein in this area a circumferential opening directed to the sealing lip for the door is arranged.

Erfindungsgemäß ist der Spannring einstückig am überstülpten Bereich der Dichtungsmanschette angeformt und weist hinsichtlich seines Umfanges ein geringes Untermaß auf, so dass in der Stützlage eine durch Dehnung verursachte Zugkraft in dem Spannring erwirkt wird, wodurch der überstülpte Bereich gegen den Umlauf der Abkantung um die Gehäuseöffnung angepresst wird.According to the invention the clamping ring is integrally formed on the over-turned portion of the gasket and has a small undersize in terms of its circumference, so that in the support layer caused by stretching tensile force is obtained in the clamping ring, whereby the invaginated area pressed against the circulation of the fold around the housing opening becomes.

Für die leichtere Montage einer Dichtungsmanschette mit einem Spannring wird ein Verfahren vorgesehen, dass zur Festlegung der Manschette für eine frontbeschickbare Wäschebehandlungsmaschine an einer Gehäuseöffnung oder einer Laugenbehälteröffnung bestimmt ist, wobei zwischen einer Gehäuseöffnung und einer Laugenbehälteröffnung die Dichtungsmanschette eingefügt ist, und wobei der Rand der Dichtungsmanschette um eine umlaufende Abkantung der Gehäuseöffnung gestülpt wird und an dem überstülpten Bereich ein an der Dichtungsmanschette einstückig mittels eines Filmscharniers angeformter Spannring vorgesehen ist, der hinsichtlich seines Umfanges ein geringes Untermaß hat, so dass beim Umklappen des Spannringes in die Stützstellung eine Dehnung hervorgerufen wird, die dem Spannring eine Zugkraft verleiht, wodurch der Spannring den überstülpten Bereich gegen die umlaufende Abkantung um die Gehäuseöffnung presst.For ease of mounting a gasket with a collet, a method is provided that defines the collar for a front-loading Laundry treatment machine is determined at a housing opening or a tub opening, wherein between a housing opening and a tub opening the gasket is inserted, and wherein the edge of the gasket is slipped around a peripheral fold of the housing opening and integrally formed on the gasket over the sealing sleeve by means of a film hinge Clamping ring is provided, which has a small undersize in terms of its circumference, so that when folding the clamping ring in the support position, an elongation is caused, which gives the clamping ring a tensile force, whereby the clamping ring presses the over-turned portion against the peripheral fold around the housing opening.

Die Figur 1 zeigt in der geschnittenen, skizzierten Darstellung eine frontbeschickbare Wäschebehandlungsmaschine 1 mit einem Gehäuse 2. Dabei verfügt das Gehäuse 2 über eine Tür 3, die eine im Wesentlichen kreisförmige Gehäuseöffnung 4 verschließt. In dem Gehäuse 2 ist ein Laugenbehälter 5 schwingbeweglich befestigt, in dem eine drehbar angeordnete Trommel 6 mit einer wenigstens annähernd horizontalen Drehachse 6a angeordnet ist. Die Trommel 6 verfügt hierbei über eine stirnseitig angeordnete im Wesentlichen kreisförmige Trommelöffnung 6b zum Einbringen oder Herausnehmen von Wäsche. Wie aus der Figur 1 in der geschnittenen Ansicht zu erkennen ist, verfügt die Wäschebehandlungsmaschine 1 über eine Dichtungsmanschette 7 zur Verbindung der Gehäuseöffnung 4 mit einer Laugenbehälteröffnung 8, wobei die Laugenbehälteröffnung 8 und die Trommelöffnung 6b von der Gehäuseöffnung 4 durch die Dichtungsmanschette 7 hindurch erreichbar ist.The FIG. 1 shows in the cut, sketched representation of a front loadable laundry treatment machine 1 with a housing 2. In this case, the housing 2 has a door 3, which closes a substantially circular housing opening 4. In the housing 2, a tub 5 is mounted swingably, in which a rotatably arranged drum 6 is arranged with an at least approximately horizontal axis of rotation 6a. The drum 6 in this case has a frontally arranged substantially circular drum opening 6b for introducing or removing laundry. Like from the FIG. 1 can be seen in the sectional view, the laundry treating machine 1 has a sealing sleeve 7 for connecting the housing opening 4 with a tub opening 8, wherein the tub opening 8 and the drum opening 6b of the housing opening 4 through the sealing sleeve 7 is reached.

Wie aus den Figuren 2 und 3 in der Detailansicht zu erkennen ist, ist die Gehäuseöffnung 4 mit einer umlaufenden Abkantung 9 dargestellt, wobei auf der umlaufenden Abkantung 9 die Dichtungsmanschette 7 gestülpt und befestigt ist. Dabei ist dieser überstülpte Bereich 10 mit einem Spannelement 11 versehen, welches wiederum mit dem überstülpten Bereich 10 zusammenwirkt. Wie aus der Figur 2 und 3 noch zu erkennen ist, ist in diesem Bereich eine umlaufende zur Türöffnung gerichtete Dichtlippe 12 für die Tür 3 angeordnet.Like from the Figures 2 and 3 can be seen in the detailed view, the housing opening 4 is shown with a circumferential fold 9, wherein on the circumferential fold 9, the gasket 7 is slipped and fastened. In this case, this everted region 10 is provided with a clamping element 11, which in turn cooperates with the over-turned-over region 10. Like from the FIG. 2 and 3 can still be seen, a circumferential door opening directed towards the sealing lip 12 is arranged for the door 3 in this area.

Wie aus der Zusammenschau der Figur 2 und 3 nun erkennbar wird, ist das Spannelement 11 ein Spannring 13, welcher einstückig am überstülpten Bereich 10 der Dichtungsmanschette 7 angeformt ist. Der Spannring 13, so wie er sich in der Figur 2 darstellt, weist hinsichtlich seines Umfanges bezogen auf den Umfang des überstülpten Bereichs 10 ein geringes Untermaß auf. Dieses Untermaß wird infolge des Umklappens in die Stellung der Figur 3 durch Überdehnung überwunden, so dass in der geklappten Stützstellung eine durch Dehnung verursachte Zugkraft in dem Spannring 13 hervorgerufen wird. Dadurch wird der überstülpte Bereich 10 gegen die umlaufende Abkantung 9 um die Gehäuseöffnung 4 gepresst, was eine feste stramme Einbindung des überstülpten Bereiches 10 an der Abkantung 9 hervorruft.As from the synopsis of FIG. 2 and 3 it can now be seen, the clamping element 11 is a clamping ring 13 which is integrally formed on the recessed portion 10 of the gasket 7. The clamping ring 13, as he is in the FIG. 2 represents, in terms of its circumference based on the circumference of the everted portion 10 a small undersize. This undersize is due to the folding into the position of FIG. 3 overcome by overstretching, so that in the folded support position caused by stretching tensile force in the clamping ring 13 is caused. As a result, the invaginated region 10 is pressed against the circumferential fold 9 around the housing opening 4, which causes a firm, tight integration of the invaginated region 10 at the fold 9.

Wie in Figur 3 dargestellt, füllt im befestigten Zustand der Spannring 13 die V-förmige Erstreckung des überstülpten Bereiches 10 aus, so dass der Spannring 13 auch noch zusätzlich eine Art Stützwirkung des oberen Schenkels des überstülpten Bereiches 10 hervorruft. Der Spannring 13 deckt somit radial außenseitig den überstülpten Bereich 10 ab und stützt diesen zudem. Der als Spannring 13 ausgebildete Abstützring nimmt von seiner Querschnittserstreckung eine Tropfenform ein, die sich im geklappten bzw. gefalteten Zustand in die Hohlkehle des überstülpten Bereiches 10 drückt und diese ausfüllt.As in FIG. 3 shown, filled in the attached state, the clamping ring 13, the V-shaped extension of the everted portion 10, so that the clamping ring 13 also causes a kind of supporting action of the upper leg of the everted region 10. The clamping ring 13 thus covers the outside of the over-taped region 10 radially and supports this also. Trained as a clamping ring 13 support ring takes from its cross-sectional extension a teardrop shape, which presses in the folded or folded state in the groove of the everted region 10 and fills them.

Der Spannring 13 nimmt in seiner geklappten bzw. gefalteten Stützstellung eine zur Dichtlippe 12 oder zur Ebene der Öffnung rechtwinklige oder zumindest nahezu rechtwinklige Stützlage ein. Dies ist insbesondere in der Figur 3 zu erkennen, wo Soll-Biegestellen für die angeformte Dichtlippe 12 am überstülpten Bereich 10 vorgesehen sind.The clamping ring 13 takes in its folded or folded support position a rectangular to the sealing lip 12 or the plane of the opening or at least almost rectangular support position. This is especially true in the FIG. 3 to recognize where desired bending points for the molded sealing lip 12 are provided on the over-turned portion 10.

In Weiterbildung der Erfindung ist der Spannring 13 mit einem Filmscharnier 14 hinter der Dichtlippe 12 angeformt und ist nach der Montage der Dichtungsmanschette 7 in die Stütz- und Spannlage klapp- bzw. faltbar. Das Filmscharnier 14 legt sich in der gefalteten Situation, dargestellt in der Figur 3, an bzw. über den oberen Bereich der Dichtungsmanschette 7 spannend an.In a further development of the invention, the clamping ring 13 is integrally formed with a film hinge 14 behind the sealing lip 12 and after folding the sealing sleeve 7 into the support and clamping position folding or foldable. The film hinge 14 settles in the folded situation, shown in the FIG. 3 , on or over the upper region of the sealing sleeve 7 exciting.

In Weiterbildung der Erfindung betrifft diese auch die Dichtungsmanschette 7 als solches für eine frontbeschickbare Wäschebehandlungsmaschine 1 mit einem Gehäuse 2 und einem Laugenbehälter 5 zur Verbindung zwischen einer Gehäuseöffnung 4 zum Einbringen oder Herausnehmen von Wäsche und einer Laugenbehälteröffnung 8, die auf eine um die Gehäuseöffnung 4 umlaufenden Abkantung 9 stülpbar ist. Dieser überstülpte Bereich 10 wirkt mit einem als Spannring 13 ausgebildeten Spannelement 11 zusammen, wobei in diesem Bereich eine umlaufende zur Türöffnung gerichtete Dichtlippe 12 angeordnet ist. Erfindungsgemäß ist hierbei an der Dichtungsmanschette 7 der Spannring 13 einstückig am überstülpten Bereich 10 angeformt, wobei der angeformte Spannring 13 hinsichtlich seines Umfanges ein geringes Untermaß aufweist, so dass in der Stützstellung eine durch Dehnung verursachte Zugkraft in dem Spannring 13 wirkt, wodurch der überstülpte Bereich 10 gegen die umlaufende Abkantung 9 um die Gehäuseöffnung 4 angepresst wird.In a further development of the invention, this also relates to the gasket 7 as such for a front loadable laundry treatment machine 1 with a housing 2 and a tub 5 for connection between a housing opening 4 for introducing or removing laundry and a suds container opening 8, which revolves around a to the housing opening 4 Fold 9 is turnable. This everted region 10 cooperates with a clamping element 11 designed as a clamping ring 13, a circumferential sealing lip 12 directed towards the door opening being arranged in this region. According to the invention, the clamping ring 13 is integrally formed on the over-turned portion 10 on the sealing sleeve 7, wherein the molded clamping ring 13 has a small undersize in terms of its circumference, so that in the support position caused by stretching tensile force acts in the clamping ring 13, whereby the recessed area 10 is pressed against the circumferential fold 9 to the housing opening 4.

Auch wird das Problem durch ein Verfahren zur Festlegung einer Dichtungsmanschette 7 für eine frontbeschickbare Wäschebehandlungsmaschine 1 mit einem Gehäuse 2 und einem Laugenbehälter 5 gelöst, wobei zwischen einer Gehäuseöffnung 4 und einer Laugenbehälteröffnung 8 die Dichtungsmanschette 7 eingefügt wird, welche um eine umlaufende Abkantung 9 der Gehäuseöffnung 4 gestülpt wird und an dem überstülpten Bereich 10 ein an der Dichtungsmanschette 7 einstückig mittels eines Filmscharniers 14 angeformter Spannring 13 vorgesehen ist, der hinsichtlich seines Umfanges bezogen auf den Umfang des überstülpten Bereichs ein geringes Untermaß hat, so dass beim Umklappen des Spannringes 13 in die Stützstellung eine Dehnung hervorgerufen wird, die dem Spannring 13 eine Zugkraft verleiht, wodurch der Spannring 13 den überstülpten Bereich 10 gegen die umlaufende Abkantung 9 der Gehäuseöffnung 4 presst.Also, the problem is solved by a method for fixing a gasket 7 for a front loadable laundry treating machine 1 with a housing 2 and a tub 5, wherein between a housing opening 4 and a tub opening 8, the sealing sleeve 7 is inserted, which is a circumferential fold 9 of the housing opening 4 is slipped and on the everted portion 10 integrally formed on the gasket 7 integrally formed by a film hinge 14 clamping ring 13 is provided, which has a small undersize in terms of its circumference on the circumference of the everted portion, so that when folding the clamping ring 13 in the Supporting an elongation is caused, which gives the clamping ring 13 a tensile force, whereby the clamping ring 13 presses the invaginated region 10 against the peripheral fold 9 of the housing opening 4.
