The clamping element can be molded into the interior of the section (which can be a beading) of the sealing sleeve to be secured.

Description

Die vorliegende Erfindung betrifft eine Dichtungsmanschette zur Abdichtung von Verbindungen in Haushaltgeräten, insbesondere der Verbindungen zwischen Außentrommel und vorderer Gehäusewand bzw. Laugenbehälteroberteil und Deckrahmen in Waschmaschinen, die mit einem im wesentlichen ringförmigen Spannelement befestigbar ist.The present invention relates to a gasket for sealing connections in household appliances, in particular the connections between the outer drum and the front housing wall or tub upper part and cover frame in washing machines, which can be fastened with a substantially annular clamping element.

Bei Waschmaschinen oder Waschtrocknern ist es wichtig, eine geeignete Abdichtung zwischen Außentrommel und vorderer Gehäusewand bei Frontlader-Maschinen bzw. zwischen Laugenbehälteroberteil und Deckrahmen bei Toplader-Geräten zu gewährleisten. Üblicherweise werden hierzu Dichtungsmanschetten verwendet, die mittels bekannter, um die Manschette gelegter Spann- oder Spann-/Schraubelemente befestigt werden können.In the case of washing machines or washer-dryers, it is important to ensure a suitable seal between the outer drum and the front housing wall in front-loading machines or between the upper part of the tub and the top frame of top-loader devices. Usually this gaskets are used, which can be fixed by means of known, placed around the sleeve clamping or clamping / screw elements.

Aus der DE-OS 2 403 705 ist eine Dichtungsmanschette bekannt, die eine abdichtende Verbindung zwischen dem Laugenbehälter einer Waschmaschine, in dem die Waschtrommel gelagert ist, und der Gehäusewand bzw. der Ladetür bildet. Dabei ist die Dichtungsmanschette an dem Laugenbehälter derart befestigt, daß sie mit einer ringförmigen Halterungs- oder Sicherungsfeder gegen die Außenfläche der Wand des Laugenbehälters gedrückt wird.From the DE-OS 2 403 705 a gasket is known, which forms a sealing connection between the tub of a washing machine, in which the washing drum is mounted, and the housing wall or the door. The gasket is attached to the tub so that it is pressed with an annular retaining or locking spring against the outer surface of the wall of the tub.

Nachteilig an der bekannten Dichtungsmanschette ist, daß ein hoher Montageaufwand zur Befestigung der Dichtungsmanschette nötig ist und daß durch die von außen anbringbaren und sichtbaren Spannelemente keine freie Ausgestaltung der Anschlußgeometrie möglich ist.A disadvantage of the known gasket is that a high installation cost for attaching the gasket is necessary and that no free design of the connection geometry is possible by the externally attachable and visible clamping elements.

Der Erfindung liegt somit die Aufgabe zugrunde, eine Dichtungsmanschette der eingangs genannten Art zu schaffen, bei der die obigen Nachteile vermieden sind, so daß neben einer verbesserten Optik der Montageaufwand reduziert wird, und die Form der zu befestigenden Abschnitte der Dichtungsmanschette äußerst variabel gestaltet werden kann.The invention is therefore an object of the invention to provide a gasket of the type mentioned, in which the above disadvantages are avoided, so that in addition to improved appearance of the assembly effort is reduced, and the shape of the sections of the gasket to be fastened can be made extremely variable ,

Diese Aufgabe wird gemäß der Erfindung dadurch gelöst, daß das Spannelement in das Innere des zu befestigenden Abschnitts der Manschette einformbar ist. Dadurch wird der Montageaufwand vor Ort erheblich reduziert, und die Form der Dichtungsmanschette kann äußerst variabel gestaltet werden. Vorteilhafterweise ist das Spannelement zudem nach außen hin nicht sichtbar.This object is achieved according to the invention in that the clamping element can be formed in the interior of the portion to be fastened of the sleeve. As a result, the assembly work on site is significantly reduced, and the shape of the gasket can be made extremely variable. Advantageously, the clamping element is also not visible to the outside.

Vorteilhafterweise weist die Dichtungsmanschette in ihrem Inneren einen ringförmigen Kanal auf, der durch mindestens eine Rille mit der Außenoberfläche der Dichtungsmanschette verbunden ist. Dadurch wird gewährleistet, daß das Spannelement einen festen und sicheren Halt in der Dichtungsmanschette hat und dennoch jederzeit von außen Zugriff auf das Spannelement besteht.Advantageously, the gasket has in its interior an annular channel which is connected by at least one groove to the outer surface of the gasket. This ensures that the clamping element has a firm and secure hold in the gasket and yet at any time from the outside access to the clamping element.

Besonders vorteilhaft kann das Spannelement vor der Montage der Dichtungsmanschette im Haushaltgerät bereits in der Dichtungsmanschette vormontiert sein, wodurch der Montageaufwand beim Einsetzen der Dichtungsmanschette noch weiter reduziert werden kann.Particularly advantageously, the clamping element can be pre-assembled in the appliance before the assembly of the gasket in the appliance already in the gasket, whereby the assembly cost when inserting the gasket can be further reduced.

Zur Vereinfachung des Herstellungsvorgangs ist es weiterhin vorteilhaft, die Dichtungsmanschette durch Spritzgießen zu bilden.To simplify the manufacturing process, it is also advantageous to form the gasket by injection molding.

Der Aufwand der Vormontage des Spannelements in der Dichtungsmanschette entfällt in vorteilhafter Weise, wenn die Manschette das Spannelement beim Spritzgießen bereits enthält.The cost of pre-assembly of the clamping element in the gasket omitted in an advantageous manner when the sleeve already contains the clamping element during injection molding.

Ist ein Wulst der Dichtungsmanschette so ausgebildet, daß es mit einem gewölbten, im wesentlichen ringförmigen Randbereich des die Türöffnung begrenzenden Endes der vorderen Gehäusewand in Eingriff kommt, so liefert das den Vorteil, daß eine hervorragend an die bisher verwendeten Waschmaschinenteile angepaßte Dichtungsmanschette geschaffen wird.If a bead of the gasket is formed so that it engages with a curved, substantially annular edge region of the door opening bounding end of the front housing wall, so that provides the advantage that a well adapted to the previously used washing machine parts gasket is provided.

Die Schnittansicht eines Türbereichs einer Frontlader-Waschmaschine in Fig. 1 zeigt eine Bullaugen-Tür 1, bestehend aus einem topfartigen Glasfenster 2, das in einem Rahmen 3 befestigt ist. Auf der Innenseite des Randbereiches der Tür 1 liegen in Verschlußstellung der Tür Dichtlippen 4 und 5 an, die ein Austreten von Wasser aus dem rechts der Tür gelegenen Innenraum der Waschmaschine nach außen verhindern.The sectional view of a door area of a front loader washing machine in Fig. 1 shows a porthole door 1, consisting of a pot-like glass window 2, which is fixed in a frame 3. On the inside of the edge region of the door 1 lie in the closed position of the door sealing lips 4 and 5, which prevent leakage of water from the right of the door located inside the washing machine to the outside.

Die Tür 1 ein ist über ein nicht gezeigtes Scharnier an einem Fensterausschnitt eines Gehäuses 6 der Waschmaschine befestigt, das im Randbereich 7 des Fensters einen vorgerollten Blechkragen 8 enthält. Auf diesen Blechkragen ist der äußere Wulst 9 einer Manschette 10 geknöpft. Ein in den Wulst eingelegtes Spannelement 11, beispielsweise eine ringförmige Schraubenfeder, spannt den Wulst 9 gegen die Kehle des Blechkragens 8.The door 1 a is attached via a hinge, not shown, to a window opening of a housing 6 of the washing machine, which contains a pre-rolled sheet metal collar 8 in the edge region 7 of the window. On this metal collar of the outer bead 9 of a sleeve 10 is buttoned. An inserted into the bead clamping element 11, for example, an annular coil spring, biases the bead 9 against the throat of the sheet metal collar. 8

Die Fig. 2 und 3 zeigen in einer vergrößerten Schnittansicht den Wulst 9 der Dichtungsmanschette 10, das einen ringförmigen Kanal 12 in seinem Inneren aufweist. Der Kanal 12 ist in Fig. 2 über eine, in Fig. 3 über zwei senkrecht zueinander angeordnete Rillen 13 bzw. 13 und 14 mit der Außenoberfläche des Wulstes 9 der Dichtungsmanschette 10 verbunden. In den ringförmigen Kanal 12 ist ein im wesentlichen ringförmiges Spannelement 11 eingeformt. Im Wulst 9 der Dichtungsmanschette 10 ist eine im ungefähr viertelkreisförmige Ausnehmung eingeformt, in die ein aufgerollter, im wesentlichen ringförmiger Kragen 8 des die Türöffnung begrenzenden Randes des vorderen Ausschnittes der Gehäusewand 7 eingeführt ist.The FIGS. 2 and 3 show in an enlarged sectional view of the bead 9 of the gasket 10, which has an annular channel 12 in its interior. The channel 12 is in Fig. 2 over one, in Fig. 3 via two mutually perpendicular grooves 13 and 13 and 14 connected to the outer surface of the bead 9 of the gasket 10. In the annular channel 12, a substantially annular clamping element 11 is formed. In the bead 9 of the gasket 10 is formed in an approximately quarter-circular recess into which a rolled, substantially annular collar 8 of the door opening bounding edge of the front cutout of the housing wall 7 is inserted.

In einer Ausführungsform gemäß Fig. 3, in der der Fenster-Randbereich 7 der vorderen Gehäusewand 6 nur einen schmalen eingetulpten Rand aufweist, empfiehlt sich zur Abdeckung dieses Randbereiches noch eine ringförmige, den Randbereich 7 abdeckende, umlaufende Lippe 16.In an embodiment according to Fig. 3 , in which the window edge region 7 of the front housing wall 6 has only a narrow recessed edge, recommends to cover this edge region still an annular, the edge region 7 covering, circumferential lip 16th

Die Herstellung der Dichtungsmanschette 10 erfolgt üblicherweise über das Spritzgießverfahren. Dabei wird eine entsprechende Form ausgestaltet und unter Hochdruck mit flüssigem und elastischem Material (z. B. Kautschuk) ausgespritzt, das später weichelastisch aushärtet, wodurch eine bis ins Detail genaue vorbestimmte Form der Dichtungsmanschette 10 gebildet werden kann.The production of the gasket 10 is usually carried out by the injection molding. In this case, a corresponding shape is configured and injected under high pressure with liquid and elastic material (eg rubber), which later cures with soft elasticity, as a result of which a precise shape of the sealing collar 10 can be formed.

Zum Einformen des Spannelements 11 in das Innere der Dichtungsmanschette 10 existieren prinzipiell zwei Möglichkeiten. Zum einen kann die Form mit einem entsprechenden Kern für den späteren Kanal 12 und mindestens eine Rille 13 oder 14 ausgestattet sein. Dann ist es nach Aushärten des Spritzgieß-Materials möglich, das Spannelement 11 über die Rille 13 oder 14 in den ringförmigen Kanal 12 im Inneren des Wulsts 9 der Dichtungsmanschette 10 einzuführen.For molding the clamping element 11 into the interior of the gasket 10, there are in principle two possibilities. On the one hand, the mold can be equipped with a corresponding core for the later channel 12 and at least one groove 13 or 14. Then, after curing of the injection molding material, it is possible to insert the clamping element 11 via the groove 13 or 14 into the annular channel 12 in the interior of the bead 9 of the sealing collar 10.

Alternativ dazu kann das ringförmige Spannelement 11 auch bereits in der Spritzform über eine ringförmige durchlaufende Rippe oder über an einzelnen Punkten der Ringform angebrachte Stege befestigt sein. Beim anschließenden Spritzgießen wird in diesem Fall das Spannelement 11 umspritzt, so daß dieses und die Dichtungsmanschette 10 eine einzige Komponente bilden und kein Einführen des Spannelements 11 in den Kanal 12 mehr nötig ist. Bei der Verwendung von einzelnen Stegen weist der Wulst 9 der Dichtungsmanschette 10 nach dem Spritzgießen keine durchgängige Rille 13 zur Verbindung des Kanals 12 mit der Außenseite der Dichtungsmanschette 10 auf sondern mehrere der Form der Haltestege entsprechende einzelne Durchtrittsöffnungen.Alternatively, the annular clamping element 11 may also already be secured in the injection mold via an annular continuous rib or via webs attached to individual points of the annular mold. In the subsequent injection molding, the clamping element 11 is overmolded in this case, so that this and the gasket 10 form a single component and no insertion of the clamping element 11 in the channel 12 is more necessary. When using individual webs of the bead 9 of the gasket 10 after injection no continuous groove 13 for connecting the channel 12 with the outside of the gasket 10 but a plurality of the shape of the holding webs corresponding individual passage openings.

Die Verwendung von mehreren kreisförmigen Rippen in der Spritzform dient für eine bessere Halterung des Spannelements 11. In einem solchen Fall entstehen nach dem Spritzgießen im Wulst 9 der Dichtungsmanschette 10 dementsprechend mehrere ringförmige Rillen 13 und 14.The use of a plurality of circular ribs in the injection mold serves for a better retention of the clamping element 11. In such a case, after injection molding in the bead 9 of the gasket 10 correspondingly more annular grooves 13 and 14.

Als Spannelement 11 können prinzipiell alle selbsttätig elastisch nachspannenden ringförmigen Konstruktionen verwendet werden, etwa auch ein Spannseil oder ein Gummiband höherer Zugkraft. Besonders bevorzugt ist allerdings der Einsatz einer Schraubenfeder, auch "Wurmfeder" genannt, da diese ihre Federkraft auch nach langer Betriebsdauer beibehält und somit eine sichere Abdichtung gewährleistet. Zu beachten ist, daß bei einem direkten Umspritzen einer Schraubenfeder diese zuvor mit einer geeigneten Umhüllung versehen werden muß, da ansonsten beim Spritzgießen Material der Manschette 10 zwischen die einzelnen Federwindungen gelangt, was zu einer Verminderung bzw. völligen Ausschaltung der Federkraft führen kann.As a clamping element 11, in principle, all automatically elastically relaxing annular structures can be used, such as a tensioning cable or a rubber band higher tensile force. However, particularly preferred is the use of a Coil spring, also called "worm spring", as it retains its spring force even after a long period of operation, thus ensuring a secure seal. It should be noted that in a direct encapsulation of a coil spring must be previously provided with a suitable enclosure, otherwise material of the sleeve 10 passes between the individual spring coils during injection molding, which can lead to a reduction or complete elimination of the spring force.

In den vorgenannten Ausführungsformen, die an die üblichen Ausführungsformen des gewölbten, im wesentlichen ringförmigen Kragens 8 des die Türöffnung begrenzenden Randsabschnittes 7 der vorderen Gehäusewand 6 angepaßt sind, wird der Wulst 9 mit dem bereits beim Spritzgießen mitumspritzten oder nach dem Spritzgießen im Kanal 12 vormontierten Spannelement 11 lediglich mit seiner viertelkreisförmigen Ausnehmung über den entsprechend geformten Kragen 8 gestülpt. Durch die Federkraft des Spannelements 11 wird der Wulst 9 der Dichtungsmanschette 10 anschließend dauerhaft gegen diesen Kragen 8 gedrückt, so daß ein Verrutschen der Dichtungsmanschette 10 verhindert wird.In the aforementioned embodiments, which are adapted to the usual embodiments of the domed, substantially annular collar 8 of the door opening bounding edge portion 7 of the front housing wall 6, the bead 9 with the mitumspritzten already in the injection molding or pre-assembled in the channel 12 after injection molding clamping element 11 slipped only with its quarter-circle-shaped recess over the correspondingly shaped collar 8. By the spring force of the clamping element 11 of the bead 9 of the gasket 10 is then pressed permanently against this collar 8, so that slipping of the gasket 10 is prevented.

Die Erfindung beschränkt sich jedoch nicht auf die vorliegend beschriebenen Ausführungsformen, sondern umfaßt alle denkbaren geometrischen Formen, angefangen vom einfachen Rechteck bis hin zu kompliziert ausgeführten Wulsten. Der zu befestigende Abschnitt der Dichtungsmanschette muß nur dick genug sein, um das Spannelement in seinem Inneren aufzunehmen. Somit ist der Gegenstand der vorliegenden Erfindung in nahezu allen Bereichen einsetzbar, bei denen Dichtungsmanschetten verwendet werden.However, the invention is not limited to the embodiments described herein, but includes all conceivable geometric shapes, ranging from the simple rectangle to intricately executed beads. The portion of the gasket to be fastened need only be thick enough to accommodate the tension member in its interior. Thus, the article of the present invention is applicable in almost all areas where gaskets are used.
