Definitions
- the invention relates to a washing machine with a sealing collar, which is substantially hollow cylindrical and is provided to surround a loading and unloading of the washing machine at its periphery, and which is fixed by means of its first end directly or indirectly on a front housing wall of the washing machine, wherein the loading and unloading opening can be closed by a pivotable porthole-shaped door, wherein in the region of the first end to an inner jacket of the gasket a lip seal is provided, which bears in the closed state of the door sealingly on the outer circumferential surface, wherein the gasket at its second end a lye container is fixable, and wherein the lip seal has a first, radially inwardly facing portion, which adjoins at least a second portion which extends substantially in the axial direction of the sealing collar and in the direction of the second end thereof.
- Washing machines which are predominantly designed as front loaders, ie from the front side laundry items can be filled or removed from a washing or centrifugal drum, have for this purpose in their front housing wall on a loading and unloading, of which a in Direction of the washing or centrifugal drum extending gasket emanates.
- This gasket is predominantly hollow cylindrical, has to compensate for movements of another end with its associated tub bellows designed areas and bridges a distance between the filling opening and an opening provided in the tub.
- the gasket is fixed in the edge region of the opening provided in the tub, wherein it is also provided at this second end also with a sealing blade, which cooperates with the edge of a filling opening of the washing or centrifugal drum.
- the lamella is intended to prevent items of laundry from entering the tub during filling of the washing machine or during the washing or spinning process out of the drum or out of the interior of the sealing sleeve.
- the front-side filling opening is closed during the washing and spinning process by a pivotable porthole-shaped door, which is usually made of glass and usually has a frusto-conical outer contour. When closing this door dives frusto-conical outer contour with its smallest diameter in advance into the interior of the gasket, wherein an outgoing of the gasket lip seal sealingly abuts the outer surface of the frustoconical door.
- a gasket of the type described above is from the document DE 10 2006 017 954 B4 known.
- the front panel of the washing machine is provided at its edge surrounding the filling opening with a flange, which engages over the gasket with a correspondingly formed bead.
- the gasket has a lip seal extending at an angle of approximately 100 ° to the cylindrical surface. If the porthole-shaped door, which has a frustoconical outer contour, closed, it displaces the sealing lip in the direction of the second end of the sealing sleeve, the sealing lip sealingly abuts the circumference of the lateral surface of the door.
- a gasket of a washing machine projecting which has a first end for fixing to a front housing wall of the washing machine and a second end for attachment to a tub.
- the gasket is also provided with a lip seal which rests against an outer surface of a bullseye-shaped door in its closed state.
- the lip seal has a first, radially inwardly facing portion, to which at least a second portion connects, said second portion extends substantially in the axial direction of the sealing collar and in the direction of the second end thereof.
- the two portions of the lip seal should be designed such that in the closed state of the door, a portion of the first portion is applied flat against the outer surface of the door, while the second portion is angled relative to the first portion and on the inner shell the gasket extends to and in the direction of the second end thereof.
- the second section extending in the axial direction may also have a V-shaped profile, as viewed in longitudinal section through the lip seal, with a lamella extending in the direction of an inner circumferential surface of the sealing collar and a further lamella in the direction of an outer circumferential surface of the door.
- the sealing of the gasket against the door and for catching the laundry entering this area is when the second section has a curved course. This can be very effectively prevented the penetration of laundry in the sealing area.
- the generally very elastic trained second portion of the lip seal can deform for trapping and rejecting laundry and thereby perform in the region in which it is angled to the first section, a pivoting movement.
- the second portion of the lip seal may be made softer compared to the first portion.
- the lip seal should be formed in the region of the planar contact of the first section and over its second section with substantially the same wall thickness. This allows the lip seal in the manufacture of the gasket in a simple injection process produced. Alternatively, of course, there is the possibility of forming the second section of the lip seal with a thinner wall than the first section in order to make this area particularly flexible and thus to improve the catching or rejecting of the items of laundry.
- the inner jacket of the gasket, the radially inwardly facing first portion and the second on the inner jacket tapered portion include an annular cavity. Associated with the elastic design of the second section very good conditions are created to avoid pinching the laundry and to supply them instead the washing process and the subsequent spin process.
- FIG. 1 a substantially hollow cylindrical gasket, which encloses a loading and unloading 2 radially.
- the gasket 1 is fixed at a first end 3 to a front housing wall 4 of a washing machine and at a second end 5 to a storage container 6.
- the front housing wall 4 on a flanging 7, which is encompassed by a first circumferential bead 8.
- the sealing sleeve 1 has a cylindrical course and finally merges into a bellows 9.
- the gasket 1 is designed so flexible that it can compensate for the movements of the tub 6 with respect to the front housing wall 4 occurring during washing or during the spin process at large amounts of laundry.
- a second bead 11 is provided at the second end 5 of the gasket 1, with which the gasket 1 is fixed to peripheral edges 10 and 12 of the tub 6.
- a rotating during a washing process or spin washing drum 13 which takes over the function of a centrifugal drum during a spin cycle and is charged from one end face arranged.
- From the second bead 11 extends in the longitudinal direction of the arrangement extending sealing blade 14 and extends to a flanged edge 15 of the washing drum 13. This is to prevent small items of laundry, which are enclosed in the interior of the washing drum 13 or in the seal sleeve Are located in the outside of the washing drum 13 lying area of the tub 6 can.
- the in the FIG. 1 illustrated washing machine also has a bullseye-shaped door 16, which, as not shown in detail, articulated on one side via a hinge on the front housing wall 4 pivotally and on its opposite side against the front housing wall 4 can be locked.
- the door 16 is preferably made of transparent glass.
- the door 16 has a frustoconical shell 17 and a circular bottom 18.
- a lip seal 19 is provided at the first end 3 of the gasket 1, as continue the FIG. 1 can be removed.
- This lip seal 19 is in this case essentially inwardly from the first bead 8 in the radial direction and, when the door 16 is closed, is in sealing contact with an outer circumferential surface 21 of the door 16 with a flat annular bearing 20.
- first portion 22 of the lip seal 19 is a second section 23, which is angled relative to the first portion 22.
- This second portion 23 is also curved in such a way that it extends to an inner circumferential surface 24 of the gasket 1 to and then parallel thereto. Due to this design of the lip seal 19, this closes against the inner circumferential surface 24 of the sealing sleeve 1 an annular cavity.
- FIG. 2 The formation of the sealing sleeve 1 in the region of its first end 3 and thus the design of the lip seal 19 is in FIG. 2 clarified. Consequently, in the FIG. 2 for the corresponding details, the same reference numerals as in FIG. 1 used.
- the in the Figures 1 and 2 illustrated lip seal 19 is, as already stated, provided with the second curved portion having a portion 23, said second portion 23 near the inner circumferential surface 24 of the gasket 1 ends.
- the lip seal 19 is in its deformed by the door 16 state.
- the first portion 22 of the lip seal 19 extends substantially radially or obliquely
- the second portion 23 of the lip seal 19 extends from the inner circumferential surface 24 of FIG Gasket 1 spaced.
- Their function is to fulfill the lip seal 19 of course in the closed state of the door 16, including on the one hand the sealing of the interior of the gasket 1 and thus the interior of the washing drum 13 and the tub 6 belongs.
- the lip seal 19 is by means of their system 20 sealingly against the outer circumferential surface 21 of the door made of glass. If the lip seal would end at this point, then laundry items could trapped between the system 20 and the outer lateral surface 21 during the washing process, these items would no longer participate in the actual washing process, they would be damaged and they would ultimately the corresponding seal the door 16 means damage the lip seal 19. According to the invention, however, the lip seal is provided with the outgoing from the first portion 22 second portion 23, which prevents due to its contour that the laundry items in the sealing area, so the system 20, arrive. These problems can be eliminated by the inventive design of the lip seal 19 consequently very effective. A corresponding shielding of the actual sealing region of the lip seal 19, ie of its planar contact 20, means that the items of laundry can no longer get into it. These advantages can be achieved with structurally simple means that are suitable for mass production.

Description
Die Erfindung betrifft eine Waschmaschine mit einer Dichtungsmanschette, die im Wesentlichen hohlzylindrisch ausgebildet und vorgesehen ist, um eine Be- und Entladeöffnung der Waschmaschine an ihrem Umfang zu umgeben, und die mittels ihres ersten Endes mittelbar oder unmittelbar an einer vorderen Gehäusewand der Waschmaschine fixierbar ist, wobei die Be- und Entladeöffnung durch eine schwenkbare bullaugenförmige Tür verschließbar ist, wobei im Bereich des ersten Endes an einem Innenmantel der Dichtungsmanschette eine Lippendichtung vorgesehen ist, die im geschlossenen Zustand der Tür dichtend an deren Außenmantelfläche anliegt, wobei die Dichtungsmanschette an ihrem zweiten Ende an einem Laugenbehälter fixierbar ist, und wobei die Lippendichtung einen ersten, radial nach innen weisenden Abschnitt aufweist, an den sich zumindest ein zweiter Abschnitt anschließt, der sich im Wesentlichen in axialer Richtung der Dichtmanschette und in Richtung von deren zweitem Ende erstreckt.The invention relates to a washing machine with a sealing collar, which is substantially hollow cylindrical and is provided to surround a loading and unloading of the washing machine at its periphery, and which is fixed by means of its first end directly or indirectly on a front housing wall of the washing machine, wherein the loading and unloading opening can be closed by a pivotable porthole-shaped door, wherein in the region of the first end to an inner jacket of the gasket a lip seal is provided, which bears in the closed state of the door sealingly on the outer circumferential surface, wherein the gasket at its second end a lye container is fixable, and wherein the lip seal has a first, radially inwardly facing portion, which adjoins at least a second portion which extends substantially in the axial direction of the sealing collar and in the direction of the second end thereof.
Waschmaschinen, die überwiegend als Frontlader ausgebildet sind, also von deren Frontseite her Wäschestücke in eine Wasch- bzw. Schleudertrommel eingefüllt oder aus dieser entnommen werden können, weisen zu diesem Zweck in ihrer frontseitigen Gehäusewand eine Be- und Entladeöffnung auf, von der eine sich in Richtung der Wasch- bzw. Schleudertrommel erstreckende Dichtungsmanschette ausgeht. Diese Dichtungsmanschette ist überwiegend hohlzylindrisch ausgebildet, weist zum Ausgleich von Bewegungen eines anderenends mit ihr verbundenen Laugenbehälters faltenbalgartig gestaltete Bereiche auf und überbrückt einen Abstand zwischen der Einfüllöffnung und einer im Laugenbehälter vorgesehenen Öffnung. Dabei ist die Dichtungsmanschette im Randbereich der im Laugenbehälter vorgesehenen Öffnung fixiert, wobei sie an diesem zweiten Ende außerdem noch mit einer Dichtlamelle versehen ist, die mit dem Rand einer Befüllöffnung der Wasch- bzw. Schleudertrommel zusammenwirkt. Die Lamelle soll verhindern, dass Wäschestücke beim Befüllen der Waschmaschine oder während des Wasch- oder Schleudervorganges aus der Trommel oder aus dem Inneren der Dichtungsmanschette in den Laugenbehälter gelangen. Die frontseitige Einfüllöffnung wird während des Wasch- und Schleudervorganges durch eine schwenkbare bullaugenförmige Tür verschlossen, die üblicherweise aus Glas hergestellt ist und zumeist eine kegelstumpfförmige Außenkontur aufweist. Beim Schließen dieser Tür taucht die kegelstumpfförmige Außenkontur mit ihrem kleinsten Durchmesser voran in das Innere der Dichtungsmanschette ein, wobei eine von der Dichtungsmanschette ausgehende Lippendichtung dichtend am Außenmantel der kegelstumpfförmigen Tür anliegt.Washing machines, which are predominantly designed as front loaders, ie from the front side laundry items can be filled or removed from a washing or centrifugal drum, have for this purpose in their front housing wall on a loading and unloading, of which a in Direction of the washing or centrifugal drum extending gasket emanates. This gasket is predominantly hollow cylindrical, has to compensate for movements of another end with its associated tub bellows designed areas and bridges a distance between the filling opening and an opening provided in the tub. In this case, the gasket is fixed in the edge region of the opening provided in the tub, wherein it is also provided at this second end also with a sealing blade, which cooperates with the edge of a filling opening of the washing or centrifugal drum. The lamella is intended to prevent items of laundry from entering the tub during filling of the washing machine or during the washing or spinning process out of the drum or out of the interior of the sealing sleeve. The front-side filling opening is closed during the washing and spinning process by a pivotable porthole-shaped door, which is usually made of glass and usually has a frusto-conical outer contour. When closing this door dives frusto-conical outer contour with its smallest diameter in advance into the interior of the gasket, wherein an outgoing of the gasket lip seal sealingly abuts the outer surface of the frustoconical door.
Eine Dichtungsmanschette der eingangs beschriebenen Gattung ist aus der Druckschrift

Es ist Aufgabe der vorliegenden Erfindung, eine Waschmaschine mit einer Abdichtung zwischen der vorgenannten Dichtungsmanschette und der Tür zu schaffen, mittels welcher ein Einklemmen und eine Beschädigung der Wäschestücke und eine Beschädigung der Abdichtung während des Betriebs der Waschmaschine sicher vermieden werden kann.It is an object of the present invention to provide a washing machine with a seal between the aforementioned gasket and the door, by means of which a pinching and damage of the laundry items and damage to the seal during operation of the washing machine can be safely avoided.
Diese Aufgabe wird, ausgehend vom Oberbegriff des unabhängigen Patentanspruchs, in Verbindung mit dessen kennzeichnenden Merkmalen gelöst. Die darauf folgenden abhängigen Patentansprüche geben jeweils vorteilhafte Weiterbildungen der Erfindung wieder.This object is achieved on the basis of the preamble of the independent claim, in conjunction with its characterizing features. The following dependent claims are each advantageous embodiments of the invention again.
Gemäß dem kennzeichnenden Teil des unabhängigen Patentanspruchs sollen die beiden Abschnitte der Lippendichtung derart ausgebildet sein, dass im geschlossenen Zustand der Tür ein Bereich des ersten Abschnittes flächig an der Außenmantelfläche der Tür anliegt, während der zweite Abschnitt gegenüber dem ersten Abschnitt abgewinkelt ist und auf den Innenmantel der Dichtungsmanschette zu und in Richtung von deren zweitem Ende verläuft.According to the characterizing part of the independent claim, the two portions of the lip seal should be designed such that in the closed state of the door, a portion of the first portion is applied flat against the outer surface of the door, while the second portion is angled relative to the first portion and on the inner shell the gasket extends to and in the direction of the second end thereof.
Mittels dieser erfindungsgemäßen Verlängerung der Lippendichtung wird ein Untergreifen der Dichtlippe verhindert. Wäschestücke, die von der rotierenden Wasch- bzw. Schleudertrommel sowie von den in dieser befindlichen Wäschestücke bis in diesen Bereich nach außen befördert werden, werden von dem zweiten auf die Innenmantelfläche der Dichtungsmanschette zulaufenden Abschnitt eingefangen und können folglich nicht in den Dichtungsbereich der Lippendichtung gelangen. Folglich können Beschädigungen sowohl der Wäschestücke als auch der Lippendichtung vermieden werden. Da diese über den zweiten Abschnitt der Lippendichtung eingefangenen Wäschestücke nicht eingeklemmt werden, gelangen sie wieder in die Wasch- bzw. Schleudertrommel zurück, d. h., sie sind auch weiterhin am Waschvorgang und am anschließenden Schleudervorgang beteiligt. Der sich in axialer Richtung erstreckende zweite Abschnitt kann dabei auch, im Längsschnitt durch die Lippendichtung gesehen, einen V-förmigen Verlauf aufweisen, wobei sich eine Lamelle in Richtung einer Innenmantelfläche der Dichtungsmanschette und eine weitere Lamelle in Richtung einer Außenmantelfläche der Tür erstrecken.By means of this inventive extension of the lip seal underreaction of the sealing lip is prevented. Items of laundry which are conveyed outwards into this area by the rotating washing or centrifugal drum and by the items of laundry located therein are caught by the second portion running onto the inner lateral surface of the sealing collar and consequently can not enter the sealing area of the lip seal. Consequently, damage to both the laundry items and the lip seal can be avoided. As these items of laundry captured via the second section of the lip seal are not trapped, they return to the washing or centrifuging drum, ie they continue to be involved in the washing process and in the subsequent spinning process. The second section extending in the axial direction may also have a V-shaped profile, as viewed in longitudinal section through the lip seal, with a lamella extending in the direction of an inner circumferential surface of the sealing collar and a further lamella in the direction of an outer circumferential surface of the door.
Von besonderem Vorteil für die Abdichtung der Dichtungsmanschette gegenüber der Tür und für das Einfangen der in diesen Bereich gelangenden Wäschestücke ist es, wenn der zweite Abschnitt einen gekrümmten Verlauf aufweist. Dadurch kann sehr wirkungsvoll das Eindringen von Wäschestücken in den Dichtungsbereich verhindert werden. Der insgesamt sehr elastisch ausgebildete zweite Abschnitt der Lippendichtung kann sich zum Einfangen und Abweisen von Wäschestücken verformen und dabei in dem Bereich, in dem er abgewinkelt zu dem ersten Abschnitt verläuft, eine Schwenkbewegung ausführen. In vorteilhafter Weise kann der zweite Abschnitt der Lippendichtung im Vergleich zum ersten Abschnitt weicher ausgebildet sein.Of particular advantage for the sealing of the gasket against the door and for catching the laundry entering this area is when the second section has a curved course. This can be very effectively prevented the penetration of laundry in the sealing area. The generally very elastic trained second portion of the lip seal can deform for trapping and rejecting laundry and thereby perform in the region in which it is angled to the first section, a pivoting movement. Advantageously, the second portion of the lip seal may be made softer compared to the first portion.
In Weiterbildung der Erfindung soll die Lippendichtung im Bereich der flächigen Anlage des ersten Abschnitts und über ihren zweiten Abschnitt mit im Wesentlichen gleicher Wandstärke ausgebildet sein. Dadurch lässt sich die Lippendichtung bei der Herstellung der Dichtungsmanschette in einem einfachen Spritzvorgang herstellen. Alternativ dazu besteht natürlich die Möglichkeit, den zweiten Abschnitt der Lippendichtung dünnwandiger als den ersten Abschnitt auszubilden, um diesen Bereich besonders flexibel zu gestalten und somit das Einfangen bzw. Abweisen der Wäschestücke zu verbessern.In a further development of the invention, the lip seal should be formed in the region of the planar contact of the first section and over its second section with substantially the same wall thickness. This allows the lip seal in the manufacture of the gasket in a simple injection process produced. Alternatively, of course, there is the possibility of forming the second section of the lip seal with a thinner wall than the first section in order to make this area particularly flexible and thus to improve the catching or rejecting of the items of laundry.
Schließlich sollen der Innenmantel der Dichtungsmanschette, der radial nach innen weisende erste Abschnitt und der zweite auf den Innenmantel zulaufende Abschnitt einen ringförmigen Hohlraum einschließen. Verbunden mit der elastischen Ausbildung des zweiten Abschnitts werden sehr gute Voraussetzungen geschaffen, ein Einklemmen der Wäschestücke zu vermeiden und diese stattdessen wieder dem Waschvorgang und dem anschließenden Schleudervorgang zuzuführen.Finally, the inner jacket of the gasket, the radially inwardly facing first portion and the second on the inner jacket tapered portion include an annular cavity. Associated with the elastic design of the second section very good conditions are created to avoid pinching the laundry and to supply them instead the washing process and the subsequent spin process.

Durch diesen Faltenbalg 9 ist die Dichtungsmanschette 1 so flexibel gestaltet, dass sie die beim Waschvorgang oder beim Schleudervorgang bei großen Wäschemengen auftretenden Bewegungen des Laugenbehälters 6 gegenüber der vorderen Gehäusewand 4 ausgleichen kann. Schließlich ist an dem zweiten Ende 5 der Dichtungsmanschette 1 eine zweite Wulst 11 vorgesehen, mit der die Dichtungsmanschette 1 an umlaufenden Rändern 10 und 12 des Laugenbehälters 6 fixiert ist.By this bellows 9, the gasket 1 is designed so flexible that it can compensate for the movements of the tub 6 with respect to the front housing wall 4 occurring during washing or during the spin process at large amounts of laundry. Finally, a
Innerhalb des Laugenbehälters 6 ist eine während eines Waschvorgangs oder Schleudervorgangs rotierende Waschtrommel 13, die während eines Schleuderganges die Funktion einer Schleudertrommel übernimmt und von einer Stirnseite her beschickt wird, angeordnet. Von der zweiten Wulst 11 geht eine in Längsrichtung der Anordnung verlaufende Dichtungslamelle 14 aus und reicht bis an einen umgebördelten Rand 15 der Waschtrommel 13. Dadurch soll verhindert werden, dass kleine Wäschestücke, die sich im Inneren der Waschtrommel 13 oder in dem von der Dichtungsmanschette umschlossenen Bereich befinden, in den außerhalb der Waschtrommel 13 liegenden Bereich des Laugenbehälters 6 gelangen können.Within the tub 6 is a rotating during a washing process or

Von diesem ersten Abschnitt 22 der Lippendichtung 19 geht ein zweiter Abschnitt 23 aus, der gegenüber dem ersten Abschnitt 22 abgewinkelt ist. Dieser zweite Abschnitt 23 ist außerdem in der Weise gekrümmt ausgebildet, dass er auf eine Innenmantelfläche 24 der Dichtungsmanschette 1 zu und im Anschluss daran parallel zu dieser verläuft. Aufgrund dieser Ausbildung der Lippendichtung 19 schließt diese gegenüber der Innenmantelfläche 24 der Dichtungsmanschette 1 einen ringförmigen Hohlraum ein.From this

Zu diesem Zweck liegt die Lippendichtung 19 mittels ihrer Anlage 20 dichtend an der Außenmantelfläche 21 der aus Glas hergestellten Tür an. Würde die Lippendichtung an dieser Stelle enden, so könnten sich Wäschestücke während des Waschvorgangs zwischen die Anlage 20 und die Außenmantelfläche 21 einklemmen, diese Wäschestücke würden nicht mehr am eigentlichen Waschvorgang teilnehmen, sie würden beschädigt und sie würden letztendlich auch die entsprechende Abdichtung der Tür 16 mittels der Lippendichtung 19 beschädigen. Erfindungsgemäß ist die Lippendichtung aber mit dem vom ersten Abschnitt 22 ausgehenden zweiten Abschnitt 23 versehen, der aufgrund seiner Kontur verhindert, dass die Wäschestücke in den Dichtungsbereich, also der Anlage 20, gelangen. Diese Probleme können durch die erfindungsgemäße Ausbildung der Lippendichtung 19 folglich sehr wirkungsvoll beseitigt werden. Eine entsprechende Abschirmung des eigentlichen Dichtungsbereichs der Lippendichtung 19, also von deren flächiger Anlage 20, führt dazu, dass die Wäschestücke nicht mehr in diesen gelangen können. Diese Vorteile lassen sich mit baulich einfachen Mitteln, die für eine Großserie geeignet sind, erzielen.For this purpose, the
