Description

Die Erfindung betrifft eine Bullaugentür für eine frontbeschickbare Wäschebehandlungsmaschine wie Waschmaschine, Waschtrockner oder Wäschetrockner welche ein Schauglas, einen Rahmen mit einem Innenring und einem Blendring, und eine im Wesentlichen transparente Sichtscheibe umfasst.The invention relates to a porthole door for a front loadable laundry treatment machine such as washing machine, washer-dryer or dryer which comprises a sight glass, a frame with an inner ring and a glare ring, and a substantially transparent lens.

Eine derartige Bullaugentür ist aus der DE 100 53 413 A1 bekannt. Die Bullaugentür umfasst ein zum Geräteinneren gewölbtes Schauglas mit einem Rahmen, der aus einem sichtbaren Abdeckrahmen und einem in geschlossenem Zustand verdeckten Halterahmen besteht. Zwischen Abdeckrahmen und Halterahmen ist das Schauglas mit dessen Umrandung gehalten. Um eine optimale Zentrierung des Schauglases zu erreichen, ist der Innendurchmesser des Halterahmens sehr genau, mit geringer Toleranz, auf den Anlagebereich des Schauglases bemessen. Eine zusätzliche Sichtscheibe auf der Außenseite der Bullaugentür deckt die zum Maschineninneren gerichtete Wölbung des Schauglases ab. Der Rand der Abdeckung befindet sich auf der Außenseite im sichtbaren Bereich. Der Festsitz wird durch eine Klemmung erreicht, wobei ein axial nach außen gerichteter Randansatz des Abdeckrahmens radial auf die Kante der Sichtscheibe drückt. Bei dieser Halterung müssen die Sichtscheibe und der Abdeckrahmen eine hohe Maßhaltigkeit aufweisen, da andernfalls eine feste und dauerhafte Klemmung nicht gewährleistet ist. Bei geringen Abweichungen der Maßhaltigkeit kann es vorkommen, dass die Teile nicht mehr zusammengefügt werden können oder dass bei zu großen Spalten auf eine zentrierte Ausrichtung geachtet werden muss. Bei einer nicht zentrierten Ausrichtung des Schauglases bzw. der Sichtscheibe besteht ferner die Gefahr, dass die Tür nach dem Schließen nicht gleichmäßig an der Türdichtung anliegt und nicht ganz dicht schließt.Such a porthole door is from the DE 100 53 413 A1 known. The porthole door includes a sight glass domed to the interior of the unit with a frame consisting of a visible cover frame and a support frame concealed in the closed position. Between the cover frame and support frame, the sight glass is held with its border. In order to achieve optimum centering of the sight glass, the inner diameter of the holding frame is very accurately, with a small tolerance, dimensioned on the contact area of the sight glass. An additional viewing window on the outside of the porthole door covers the curvature of the sight glass directed towards the interior of the machine. The edge of the cover is on the outside in the visible area. The interference fit is achieved by a clamping, wherein an axially outwardly directed edge approach of the cover presses radially on the edge of the window. In this holder, the lens and the cover must have a high dimensional stability, otherwise a firm and permanent clamping is not guaranteed. In the case of small deviations in the dimensional accuracy, it may happen that the parts can no longer be joined together or that, if the gaps are too large, a centered alignment must be ensured. In the case of a non-centered alignment of the sight glass or the viewing window, there is also the risk that the door does not rest evenly on the door seal after closing and does not close very tightly.

Aus der DE 195 15 040 C2 ist ebenfalls eine Bullaugentür mit einer Sichtscheibe bekannt. Hierbei ist die Sichtscheibe im Randbereich zumindest teilweise unter einem Randfortsatz des Abdeckrahmens gegen einen elastischen Ring geklemmt. Hierbei ist ein sichtbarer Spalt zwischen dem Rand der Sichtscheibe und dem inneren Rand des Abdeckrahmens vorhanden, wobei die Sichtscheibe und der Abdeckrahmen eine Maßhaltigkeit mit geringen Toleranzen aufweisen müssen. Nur dann ist sichergestellt, dass der sichtbare Spalt sehr schmal ist und keine sichtbaren Unterschiede aufweist.From the DE 195 15 040 C2 is also a porthole door with a lens known. Here, the lens in the edge region is at least partially clamped under an edge extension of the cover frame against an elastic ring. Here, a visible gap between the edge of the lens and the inner edge of the cover frame is present, wherein the lens and the cover must have a dimensional accuracy with low tolerances. Only then is it ensured that the visible gap is very narrow and has no visible differences.

Aus der DE 101 37 918 C1 ist eine Tür für eine frontbeschickbare Wäschebehandlungsmaschine bekannt, die zum Einbau in einer Küchenzeile geeignet ist. Hierbei wird das Schauglas an einer geschlossenen Verblendungsplatte befestigt. Zur Vereinfachung der Montage wird hierbei an der Verblendungsplatte ein Zentrierring angebracht, der einen erhöhten umlaufenden Rand besitzt. Über diesen Rand wird der Innendurchmesser des Schauglases gestülpt, wodurch das Schauglas in die vorgesehene Position gebracht wird. Der Zentrierring ist bereichsweise elastisch ausgebildet, damit Höhenunterschiede des umlaufenden Randes des Schauglases ausgeglichen werden können.From the DE 101 37 918 C1 For example, a door is known for a front loadable laundry treating machine that is suitable for installation in a kitchenette. Here, the sight glass is attached to a closed veneer plate. To simplify the assembly will in this case attached to the facing plate a centering ring, which has a raised peripheral edge. Over this edge, the inner diameter of the sight glass is slipped, whereby the sight glass is brought into the intended position. The centering ring is partially elastic designed so that differences in height of the peripheral edge of the sight glass can be compensated.

Der Erfindung stellt sich somit die Aufgabe, eine Bullaugentür der genannten Art hinsichtlich der Maßhaltigkeit und Dichtigkeit zu verbessern.The invention thus has the task of improving a porthole door of the type mentioned in terms of dimensional accuracy and tightness.

Erfindungsgemäß wird dieses Problem durch eine Bullaugentür mit den Merkmalen des Patentanspruchs 1 gelöst. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung ergeben sich aus den nachfolgenden Unteransprüchen.According to the invention this problem is solved by a porthole door with the features of claim 1. Advantageous embodiments and further developments of the invention will become apparent from the following subclaims.

Die mit der Erfindung erreichbaren Vorteile bestehen neben einer sehr guten Maßhaltigkeit der einzelnen Teile zueinander auch in einer guten und zuverlässigen Dichtigkeit der Tür. Das Schauglas ragt im geschlossenen Zustand in die Beladungsöffnung hinein und liegt an der Türdichtung, die um den Rand der Beladungsöffnung angeordnet ist, an. Durch eine gleichmäßige Anlage ist eine zuverlässige Dichtigkeit gewährleistet. Die Maßhaltigkeit des Schauglases innerhalb des Rahmens wird durch zumindest ein Zentriermittel bereitgestellt, welches am Rahmen angeordnet ist. Das Zentriermittel liegt federnd an dem umlaufenden Rand des Schauglases an, und dadurch wird das Schauglas in einer im Wesentlichen zentrierten Lage innerhalb des Rahmens positioniert. Das bzw. die Zentriermittel bewirken auf den Rand des Schauglases jeweils eine radial wirkende Kraft, die über den umlaufenden Rand an mehreren Stellen auf das Schauglas einwirkt. Dadurch ergibt sich selbständig eine im Wesentlichen zentrierte Lage des Schauglases im Rahmen.The achievable with the invention advantages are in addition to a very good dimensional accuracy of the individual parts to each other in a good and reliable tightness of the door. The sight glass protrudes in the closed state into the loading opening and is located on the door seal, which is arranged around the edge of the loading opening to. A uniform system ensures reliable sealing. The dimensional accuracy of the sight glass within the frame is provided by at least one centering means which is arranged on the frame. The centering means resiliently abuts the peripheral edge of the sight glass and thereby position the sight glass in a substantially centered position within the frame. The or the centering effect on the edge of the sight glass each have a radially acting force acting on the sight glass over the peripheral edge at several points. This results automatically a substantially centered position of the sight glass in the frame.

In einer weiteren Ausführungsform besitzt die Bullaugentür auf der Außenseite eine Sichtscheibe, welche die Wölbung des Schauglases, die zumindest teilweise in die Beladungsöffnung ragt, abdeckt. Am Rahmen ist zumindest ein weiteres Zentriermittel angeordnet, welches an dem umlaufenden Rand der Sichtscheibe federnd anliegt und dadurch die Sichtscheibe in einer im Wesentlichen zentrierten Lage innerhalb des Rahmens positioniert. Die Zentrierung geschieht auf die gleich Weise, wie für das Schauglas.In a further embodiment, the porthole door on the outside has a viewing window, which covers the curvature of the sight glass, which projects at least partially into the loading opening. At least one further centering means is arranged on the frame, which resiliently bears against the peripheral edge of the viewing window and thereby positions the viewing window in a substantially centered position within the frame. The centering happens in the same way as for the sight glass.

In beiden Fällen ist es zweckmäßig, dass das Zentriermittel mehrere federnde Elemente besitzt, die umlaufend im Wesentlichen gleichmäßig verteilt sind, wobei das Zentriermittel federnde Elemente für das Schauglas, und ferner federnde Elemente für die Sichtscheibe umfasst. Die federnden Elemente für das Schauglas werden in ihrer Wirkungsweise nicht von der Sichtscheibe beeinflusst, so dass die Zentrierung des Schauglases unabhängig von der Zentrierung der Sichtscheibe erfolgt.In both cases, it is expedient that the centering means has a plurality of resilient elements which are circumferentially distributed substantially uniformly, wherein the centering means comprises resilient elements for the sight glass, and further resilient elements for the viewing window. The resilient elements for the sight glass are not affected by the viewing window in their mode of action, so that the centering of the sight glass is independent of the centering of the lens.

In einer zweckmäßigen Ausführungsform ist das Zentriermittel als Kreisringabschnitt ausgebildet. An den Abschnitten sind jeweils die federnden Elemente für das Schauglas und die federnden Elemente für die Sichtscheibe angeordnet, wobei mehrere kreisringabschnittsförmige Zentriermittel umlaufend um den Rand des Schauglases und/oder der Sichtscheibe am Blendring oder am Innenring des Rahmens angeordnet sind.In an expedient embodiment, the centering means is designed as a circular ring section. At the sections in each case the resilient elements for the sight glass and the resilient elements for the lens are arranged, wherein a plurality of annular center-shaped centering circumferentially around the edge of the sight glass and / or the lens on the diaphragm ring or on the inner ring of the frame are arranged.

In einer weiteren Ausführungsform umfasst das Zentriermittel einen Ring, an dem die federnden Elemente für das Schauglas und die Sichtscheibe angeordnet sind, wobei der Ring an dem Blendring oder Innenring des Rahmens angeordnet bzw. fixiert ist. Durch die feste Anordnung der federnden Elemente ist sichergestellt, dass die federnden Elemente jeweils ihre vorgegebene Position einhalten. Eine Verschiebung der federnden Elemente bei der Montage oder beim Betrieb der Wäschebehandlungsmaschine wird hierdurch verhindert.In a further embodiment, the centering means comprises a ring on which the resilient elements for the sight glass and the viewing window are arranged, wherein the ring is arranged or fixed on the aperture ring or inner ring of the frame. The fixed arrangement of the resilient elements ensures that the resilient elements each comply with their predetermined position. A displacement of the resilient elements during assembly or operation of the laundry treatment machine is thereby prevented.

Hierbei ist es zweckmäßig, dass das Zentriermittel mit dem Ring und den federnden Elementen einstückig ausgeführt ist. Aufgrund der geringen Anzahl von Einzelteilen ist das Zentriermittel einfach herzustellen, beispielsweise als Stanz-Biegeteil aus Metall oder als spritzgegossenes Kunststoffteil. Ferner braucht nur ein einziges Teil bei der Montage berücksichtigt werden.It is expedient that the centering means is made in one piece with the ring and the resilient elements. Due to the small number of items, the centering is easy to manufacture, for example, as a stamped-bent part made of metal or injection-molded plastic part. Furthermore, only a single part needs to be considered during assembly.
