Description

Die Erfindung betrifft eine Bullaugentür für eine von vorn beschickbare Trommelwaschmaschine mit einem am Waschmaschinengehäuse scharnierten Rahmen aus einem Tragring und einem Haltering und mit einem in Richtung auf den Trommelinnenraum hin topfförmig eingezogenen Schauglas, das etwa in der Ebene des äußeren Halteringes des Rahmens mit einer Abdeckung gegen Zugriff geschützt ist, wobei der Rand der Abdeckung am Rahmen befestigt ist,The invention relates to a porthole door for a front-loading drum washing machine with a frame hinged to the washing machine housing from a support ring and a retaining ring and with a towards the drum interior cup-shaped sighted sight glass, approximately in the plane of the outer retaining ring of the frame with a cover against Access is protected, with the edge of the cover is attached to the frame,

Eine derartige Bullaugentür ist durch DE 195 15 040 C2 bekannt. Darin wird als Abdeckung ein leicht gewölbtes Glas verwendet, dessen Rand stufenförmig abgesetzt ist, damit an seiner Außenseite ein Ringraum entsteht, in den der Flansch eines Blendringes so Platz findet, dass die Außenflächen des Blendringes und des Glases der Abdeckung ungefähr flächenbündig sind.Such a porthole door is known from DE 195 15 040 C2. Therein, a slightly curved glass is used as the cover, the edge of which is stepped, so that on its outer side an annular space is formed, in which the flange of a blend ring finds enough space, that the outer surfaces of the blend ring and the glass of the cover are approximately flush.

Das Glas für eine solche Abdeckung muss in einer Form gepresst werden, was ringförmige Rillen im Glas zurück lassen kann, so dass die an den Rillen erzeugten Strahlenbrechungen ein unästhetisches Bild ergeben. Außerdem sind Pressgläser extrem ungenau in ihren Abmessungen, so dass Montageteile immer einen verhältnismäßig großen Spielraum zum Glaskörper haben müssen. Dadurch sind große Spalte zwischen den Einzelteilen einer Bullaugentür gemäß Stand der Technik hinzunehmen.The glass for such a cover must be pressed in a mold, which can leave behind annular grooves in the glass, so that the refractions generated at the grooves give an unaesthetic image. In addition, press glasses are extremely inaccurate in their dimensions, so that mounting parts must always have a relatively large margin to the glass body. As a result, large gaps between the items of a porthole door according to the prior art are added.

Der Erfindung liegt die Aufgabe zugrunde, eine Bullaugentür der eingangs genannten Art so auszubilden, dass weniger komplizierte Rahmenteile verwendet werden können, dass die Passungen zwischen den Einzelteilen einer Bullaugentür enger sein können und dass das äußere Erscheinungsbild der Bullaugentür den modernen ästhetischen Vorstellungen entspricht.The invention has the object of providing a porthole door of the type mentioned in such a way that less complicated frame parts can be used, that the fits between the parts of a porthole door can be narrower and that the appearance of the porthole door meets modern aesthetic expectations.

Erfindungsgemäß wird diese Aufgabe bei einer eingangs beschriebenen Bullaugentür dadurch gelöst, dass die Abdeckung aus einem über einer Modellform abgekühlten Flachglas besteht. Ein solches Flachglas kann so homogen gezogen werden, dass unregelmäßige Strahlenbrechungen weitgehend auszuschließen sind. Kühlen frisch gezogene Flachgläser auf gewünschten Modellformen, z. B. Kalottenformen, ab, so folgen sie der Oberflächenform und verlieren dennoch nicht ihre homogene Struktur. Dadurch können Abdeckungen der erfindungsgemäßen Art ästhetische Ansprüche bei einer Bullaugentür befriedigen. Sie sind außerdem mit erheblich geringeren Toleranzen herstellbar, weil ihre äußere Form und ihre Abmessungen erst nach Abkühlen durch Einsatz von Schneidtechniken für harte Gläser bestimmt werden und können daher durch erheblich filigranere Teile am Rahmen der Bullaugentür gehalten werden.According to the invention this object is achieved in a porthole door described above in that the cover consists of a cooled over a model mold flat glass. Such a flat glass can be pulled so homogeneously that irregular refractions are largely ruled out. Cool freshly drawn flat glasses on desired model forms, z. B. dome shapes, so they follow the surface shape and yet do not lose their homogeneous structure. As a result, covers of the type according to the invention can satisfy aesthetic demands in a porthole door. They are also manufactured with significantly lower tolerances, because their outer shape and dimensions only after cooling by using cutting techniques be determined for hard glasses and can therefore be held by considerably filigree parts on the frame of the porthole door.

Eine vorteilhafte Weiterbildung der Erfindung ist daher dadurch gekennzeichnet, dass die Abdeckung an ihrer schmalen Mantelseite vom Haltering umfasst ist. Der Haltering kann an der Peripherie der Abdeckung daher derartig filigran und flächenbündig ohne Spalte zwischen sich und der Abdeckung gestaltet sein, dass mit einer derartig gehaltenen Abdeckung dem Anspruch an neuartig ästhetische Formung der Bullaugentür entsprochen werden kann.An advantageous development of the invention is therefore characterized in that the cover is included on its narrow shell side of the retaining ring. The retaining ring can therefore be designed on the periphery of the cover so filigree and flush with no gap between them and the cover that can be met with such a cover held the claim of novel aesthetic shaping of Bullaugentür.

In besonders vorteilhafter Weise kann dieser Anspruch dadurch unterstützt werden, dass der Haltering eine Flachpartie hat, die von innen am Rand der Abdeckung anliegt. Dadurch können zugleich die Teile für die Befestigung der Abdeckung vermindert werden, so dass insgesamt ein Kostenvorteil für die Herstellung der Bullaugentür erzielt wird.In a particularly advantageous manner, this claim can be supported by the fact that the retaining ring has a flat portion, which rests from the inside at the edge of the cover. As a result, at the same time the parts for the attachment of the cover can be reduced, so that overall a cost advantage for the production of the portholes door is achieved.

Wenn der Haltering entsprechend einer weiteren vorteilhaften Ausführungsform der Erfindung zweiteilig ausgebildet ist und aus einem die Flachpartie enthaltendem Teil sowie einem Druckring mit einem Außendurchmesser gleich dem Innendurchmesser der Flachpartie besteht und wenn außerdem der Druckring zwischen der Innenseite der Abdeckung einerseits und der Außenseite eines Flansches des Schauglases sowie Stützflächen an der Vorderseite des Tragringes eingespannt ist, kann die Abdeckung bei der Montage der Bullaugentür zuerst mit dem die Flachpartie enthaltenden Teil und dem Druckring beispielsweise durch Klebetechnik miteinander verbunden werden, ohne bei der Montage auf mehrere lose Teile und deren richtigen Sitz achten zu müssen. Dadurch ist eine genauere Verbindung zwischen den Rahmenteilen und der Abdeckung möglich.If the retaining ring is formed in two parts according to a further advantageous embodiment of the invention and consists of a flat part containing part and a pressure ring with an outer diameter equal to the inner diameter of the flat portion and if also the pressure ring between the inside of the cover on the one hand and the outside of a flange of the sight glass As well as support surfaces is clamped to the front of the support ring, the cover can be connected to the flat part containing part and the pressure ring, for example, by gluing technique during installation of the Bullaugentür first, without having to pay attention to several loose parts and their correct fit during assembly , This allows a more accurate connection between the frame parts and the cover.

Eine vorteilhafte Optik enthält die Bullaugentür nach einer weiteren bevorzugten Ausführungsform dadurch, dass das die Flachpartie enthaltende Teil des Halteringes einen schmalen, den Rand der Abdeckung in einer Breite kleiner als die Dicke der Abdeckung nach vorn übergreift.According to a further preferred embodiment, the porthole door has an advantageous appearance in that the part of the retaining ring containing the flat part has a narrow edge, which engages over the edge of the cover in a width smaller than the thickness of the cover towards the front.

Die ästhetische Anmutung der Bullaugentür wird insbesondere dadurch unterstützt, dass die Abdeckung mit dem Haltering verklebt ist. Dabei entfallen optisch möglicherweise störende Befestigungseinrichtungen. Der Haltering kann gemäß besonderer Weiterentwicklung der Erfindung auch mit der vorderen Stirnfläche des Schauglases verklebt sein. Dadurch ist bei der Montage der Bullaugentür ein schrittweises Vorgehen möglich, bei dem auf vollflächigen und zentrierten Sitz der Teile zueinander ohne Probleme geachtet werden kann.The aesthetic appearance of the porthole door is particularly supported by the fact that the cover is glued to the retaining ring. This eliminates optically disturbing fastening devices. The retaining ring may be glued according to a particular development of the invention with the front end face of the sight glass. As a result, a step-by-step approach is possible during assembly of the porthole door, in which the parts can be paid attention to each other without problems on full-surface and centered seat.

In einer anderen vorteilhaften Weiterentwicklung der Erfindung ist die Abdeckung mit der Randpartie des aus thermoplastischem Kunststoff hergestellten Halteringes umspritzt. Beispielsweise kann die Abdeckung einen leicht konisch gestalteten Rand haben, dessen schräge Fläche durch die Randpartie des thermoplastisch geformten Halteringes ausgefüllt wird und dadurch bereits am Haltering gehalten werden kann.In another advantageous development of the invention, the cover is encapsulated with the edge part of the retaining ring made of thermoplastic material. For example, the cover may have a slightly conically shaped edge, the oblique surface is filled by the edge portion of the thermoplastic-shaped retaining ring and thus can be already held on the retaining ring.

FIG. 2
an inventively designed porthole door in vertical section along the section line AA in Figure 1.

Die in Figur 1 dargestellte Waschmaschine 1 enthält eine Bullaugentür 2 zum Verschließen der Beschickungsöffnung 3. Die Bullaugentür ist seitlich an der Beschickungsöffnung 3 scharniert und enthält einen Rahmen 4 mit anmontiertem, topffömig gepresstem Schauglas 5, das die Tiefe der Beschickungsöffnung 3 soweit ausfüllt, dass die kreisfömige Innenfläche des Schauglases 5 etwa bündig mit der Öffnung einer nicht dargestellten, innerhalb der Waschmaschine sich drehenden Wäschetrommel liegt.The washing machine 1 shown in Figure 1 includes a porthole door 2 for closing the feed opening 3. The porthole door is laterally hinged to the feed opening 3 and includes a frame 4 with mounted, topffömig pressed sight glass 5, which fills the depth of the feed opening 3 so far that the circular inner surface of the sight glass 5 is approximately flush with the opening of a washing drum, not shown, rotating within the washing machine.

Die in Figur 2 geschnitten dargestellte Bullaugentür 2 enthält einen dreiteiligen Rahmen 4, dessen Tragring 6 einen im wesentlichen winkelförmigen Querschnitt hat und einerseits dazu dient, den vorderen Flansch 7 des Schauglases 5 zu halten, und andererseits als Anlage und Einfassung für den Haltering 8, der zur Befestigung der Abdeckung 9 an dessen etwa zylindrischen Rand dient. Dabei besteht der Haltering aus einem die innen am Rand 10 der Abdeckung 9 liegende Flachpartie 11 enthaltenden Teil sowie einem Druckring 12, dessen Außendurchmesser gleich dem Innendurchmesser des Druckrings 12 ist. Der Druckring 12 hat einen V-förmigen Querschnitt mit sehr spitzem Öffnungswinkel, so dass die Schenkel des V leicht elastisch zusammen gedrückt werden können. Dies ist erforderlich, damit Dickentoleranzen des Flansches 7 des Schauglases 5 ausgeglichen werden können, wenn der Druckring 12 unter Spannung zwischen der Randpartie 10 der Abdeckung 9 und dem Flansch 7 des Schauglases 5 eingespannt wird. Diese Spannung hält den Flansch 7 zwischen dem Druckring 12 und dem Tragring 6 fest. Die Verbindung zwischen dem Haltering 8 einerseits und dem Tragring 6 andererseits kann entweder durch Klebung an den einander berührenden Flächen oder über mehrere am Umfang verteilte Abstandsbolzen 13 von der Innenseite des Tragrings 6 her verschraubt werden.The porthole door 2 shown cut in Figure 2 includes a three-part frame 4, the support ring 6 has a substantially angular cross section and on the one hand serves to hold the front flange 7 of the sight glass 5, and on the other hand as a plant and enclosure for the retaining ring 8, the for fastening the cover 9 at its approximately cylindrical edge is used. In this case, the retaining ring consists of a inside lying on the edge 10 of the cover 9 flat part 11 containing part and a pressure ring 12 whose outer diameter is equal to the inner diameter of the pressure ring 12. The pressure ring 12 has a V-shaped cross section with a very acute opening angle, so that the legs of the V can be easily pressed together elastically. This is necessary so that thickness tolerances of the flange 7 of the sight glass 5 can be compensated when the pressure ring 12 is clamped under tension between the edge portion 10 of the cover 9 and the flange 7 of the sight glass 5. This tension holds the flange 7 between the pressure ring 12 and the support ring 6 fixed. The connection between the retaining ring 8 on the one hand and the support ring 6 on the other hand, either by gluing to the touching surfaces or over several on Scope distributed spacer bolts 13 are screwed from the inside of the support ring 6 ago.

In hier nicht näher dargestellter Weise kann die schmale äußere Mantelfläche der Abdeckung 9 am Rand 10 so angeschrägt sein, dass die kreisförmige Außenfläche der Abdeckung einen geringeren Durchmesser hat als die Innenfläche. Dann kann der die Flachpartie 11 enthaltende Teil des Halteringes 8 als Umspritzung der Randpartie 10 der Abdeckung 9 ausgebildet sein, wodurch sich eine bündige Anordnung der schmalen ringförmigen Außenfläche der Verspritzung mit der Außenfläche der Abdeckung 9 erzielen lässt. Der zylindrische Teil des Tragrings 6 kann dann ebenfalls außenflächenbündig mit der Umspritzung angeordnet sein, oder der zylindrische Teil des Tragrings 6 kann überhaupt an der Innenfläche des Halterings 8 enden und anliegen, dort eventuell verklebt sein. Dann ergeben sich so schmale Ringflächen der Umspritzung des Teiles mit der Flachpartie 11 um die Abdeckung 9 herum, dass sich dadurch ein ästhetisch anmutendes Bullauge in besonders einfacher Weise erzielen lässt.In a manner not shown here, the narrow outer surface of the cover 9 can be bevelled at the edge 10 so that the circular outer surface of the cover has a smaller diameter than the inner surface. Then, the flat part 11 containing part of the retaining ring 8 may be formed as encapsulation of the edge portion 10 of the cover 9, whereby a flush arrangement of the narrow annular outer surface of the injection with the outer surface of the cover 9 can be achieved. The cylindrical part of the support ring 6 can then also be arranged flush with the outside of the encapsulation, or the cylindrical part of the support ring 6 can ever end on the inner surface of the retaining ring 8 and be there possibly glued. Then, such narrow annular surfaces of the encapsulation of the part with the flat part 11 around the cover 9 around, that thereby an aesthetically pleasing porthole can be achieved in a particularly simple manner.
