Aus der EP 1 762 650 A2 geht eine Bullaugentür für eine frontbeschickbare Wäschebehandlungsmaschine hervor, welche Tür ein Schauglas mit einem Rahmen und eine im Wesentlichen transparente Sichtscheibe umfasst. Der Rahmen, welcher das Schauglas trägt, enthält einen Blendring und einen Innenring. Die Sichtscheibe ist mit dem Blendring verbunden, wodurch ein einstückiges Teil bereitgestellt wird, wobei die Sichtscheibe den Blendring auf der Frontseite überdeckt.From the EP 1 762 650 A2 For example, there is a porthole door for a front loadable laundry treating machine, which door includes a sight glass with a frame and a substantially transparent lens. The frame, which carries the sight glass, contains a blend ring and an inner ring. The viewing window is connected to the blind ring, whereby an integral part is provided, wherein the viewing window covers the blind ring on the front side.

Eine Waschmaschinentür mit einer herkömmlichen Befestigungsstruktur für eine Abdeckung ist in Fig. 3 und Fig. 4 gezeigt.A washing machine door with a conventional mounting structure for a cover is in FIG. 3 and FIG. 4 shown.

Fig. 3 zeigt einen Ausschnitt aus einer Schnittdarstellung einer Tür 10 einer Wasch- und/oder Trockenmaschine gemäß dem Stand der Technik. Die Tür 10 kann in bekannterweise seitlich an einer Beschickungsöffnung scharniert werden. Die Tür 10 weist ein Schauglas 12 und einen Rahmen 14 auf. Das Schauglas 12 ist im Wesentlichen topfförmig ausgebildet und weist einen flanschförmig ausgebildeten Rand 16 auf. Der Rahmen 14 weist einen Blendring 18 mit einem Haltering 20 und einen Befestigungsring 22 auf. Der flanschförmige Rand 16 des Schauglases 12 ist zwischen dem Haltering 20 und dem Befestigungsring 22 so angeordnet, dass das Schauglas 12 im Bereich des Rands 16 zwischen dem Blendring 18 und dem Befestigungsring 22 über den Haltering 20 eingespannt ist. Fig. 3 shows a section of a sectional view of a door 10 of a washing and / or drying machine according to the prior art. The door 10 can be hinged in a known manner laterally at a feed opening. The door 10 has a sight glass 12 and a frame 14. The sight glass 12 is substantially cup-shaped and has a flange-shaped edge 16. The frame 14 has an aperture ring 18 with a retaining ring 20 and a fastening ring 22. The flange-shaped edge 16 of the sight glass 12 is arranged between the retaining ring 20 and the fastening ring 22 so that the sight glass 12 is clamped in the region of the edge 16 between the aperture ring 18 and the fastening ring 22 via the retaining ring 20.

Des Weiteren ist zwischen dem Haltering 20 und dem Blendring 8 ein Spalt 24 vorgesehen, der sich im Wesentlichen in einer radialen Richtung des Schauglases 12 erstreckt. In den Spalt 24 kann eine Abdeckung 26 eingesetzt werden, wie der Fig. 1 zu entnehmen ist. Die Abdeckung 26 kann aus Silikatglas oder aus einem Kunststoff sein, wobei sie transparent, klar oder eingefärbt bzw. vollständig undurchsichtig sein kann. Die Abdeckung 26 dient vor allem dem Schutz von bedienenden Personen vor dem Zugriff zum Schauglas 12, das sich während des Betriebs der Wasch- und/oder Trockenmaschine mit Temperaturen oberhalb von 60° Celsius unangenehm oder gefährlich stark erhitzen kann. Die Abdeckung 26 ist außerdem als Dekorationsobjekt geeignet, das nach Bedarf z.B. von Designem gestaltet sein kann.Furthermore, a gap 24 is provided between the retaining ring 20 and the diaphragm ring 8, which extends substantially in a radial direction of the sight glass 12. In the gap 24, a cover 26 may be used as the Fig. 1 can be seen. The cover 26 may be made of silicate glass or of a plastic, wherein it may be transparent, clear or colored or completely opaque. The cover 26 is mainly used to protect people from access to the sight glass 12, which can be uncomfortable or dangerous heat during operation of the washing and / or drying machine with temperatures above 60 ° Celsius. The cover 26 is also suitable as a decorative object, which can be designed as required by design, for example.

Fig. 4 entspricht im Wesentlichen der Darstellung der Fig. 3, wobei die Abdeckung 26 entfernt ist. Wie der Darstellung zu entnehmen ist, ist der Spalt 24 freigelegt. Dadurch können sich Gegenstände, wie z. B. Schmutz und Staub, in dem Spalt 24 ansammeln. Da die Abdeckung 26 relativ dünn ist, ist der Spalt 24 entsprechend räumlich eng bemessen. Finger einer menschlichen Hand können üblicherweise nicht in den Spalt 24 greifen bzw. hineingesteckt werden. Daher ist der Spalt 24 für Reinigungszwecke fast nicht zugänglich. Dieser Spalt 24 ist, wenn die Abdeckung 26 entfernt ist, auch unter ästhetischen Gesichtspunkten nicht akzeptabel, da ein derartiger Spalt 24 vom Verbraucher allgemein als optisch störend empfunden wird. Fig. 4 corresponds essentially to the representation of the Fig. 3 with the cover 26 removed. As can be seen from the illustration, the gap 24 is exposed. As a result, items such. As dirt and dust in the gap 24 accumulate. Since the cover 26 is relatively thin, the gap 24 is dimensioned correspondingly spatially. Fingers of a human hand usually can not reach into the gap 24 or be inserted. Therefore, the gap 24 is almost inaccessible for cleaning purposes. This gap 24 is, if the cover 26 is removed, not acceptable from an aesthetic point of view, since such a gap 24 is generally perceived by the consumer as visually disturbing.

Die vorstehend genannten Türen können nicht bzw. werden nicht ohne die Abdeckung verwendet, da sie ansonsten einen Spalt bzw. Schlitz zwischen dem Rahmen und dem Schauglas aufweisen würden. Ein solcher Spalt bzw. Schlitz ist unter ästhetischen Gesichtspunkten nicht akzeptabel. Außerdem kann sich dort Schmutz, wie beispielsweise Staub, ansammeln, der auf Grund einer mangelnden Zugriffsmöglichkeit nur schwer bis gar nicht zu entfernen ist.The above-mentioned doors can not be used without the cover, otherwise they would have a gap between the frame and the sight glass. Such a gap or slot is not acceptable from an aesthetic point of view. In addition, dirt, such as dust, can accumulate there, which is difficult or impossible to remove due to a lack of accessibility.

Es ist daher eine Aufgabe der Erfindung, eine Tür mit einer Abdeckung für ein Schauglas anzugeben, wobei die Abdeckung als getrenntes Bauteil einfach, das heißt mit möglichst wenigen Arbeitsschritten, an der Tür angebracht werden kann und die Tür bei Verwendung ohne die Abdeckung so gestaltet sein soll, dass sich kein Schmutz oder ähnliches an der Stelle ansammeln kann, an der die Abdeckung anzubringen wäre. Angegeben werden soll auch eine Wasch- und/oder Trockenmaschine mit einem Maschinengehäuse und einer solchen Tür.It is therefore an object of the invention to provide a door with a cover for a sight glass, the cover as a separate component simply, that is, with as few steps, can be attached to the door and the door in use without the cover to be designed is to prevent dirt or the like from accumulating at the point where the cover should be attached. It should also be given a washing and / or drying machine with a machine housing and such a door.

Diese Aufgabe wird durch eine Tür einer Wasch- und/oder Trockenmaschine sowie eine Wasch- und/oder Trockenmaschine gemäß jeweiligem unabhängigem Patentanspruch gelöst.This object is achieved by a door of a washing and / or drying machine and a washing and / or drying machine according to respective independent claim.

Der Erfindung liegt die Idee zugrunde, eine Abdeckung für ein Schauglas als ein optionales Bauteil für eine Tür einer Wasch- und/oder Trockenmaschine und die entsprechende Tür einer Wasch- und/oder Trockenmaschine so auszubilden, dass, falls die Abdeckung nicht angebracht ist, kein Spalt oder ähnlicher Freiraum in oder an dem Rahmen gebildet ist, in dem sich Schmutz oder dergleichen ansammeln kann und unter ästhetischen Gesichtspunkten nachteilig ist, so dass immer der gleiche Rahmen verwendet werden kann. Insbesondere ist die Ausbildung der Abdeckung derart, dass sie durch die besondere Formgebung in Wirkverbindung mit einem entsprechend ausgebildeten Bereich bzw. Abschnitt eines Rahmens der Tür an demselben gehalten wird. Dies wird dadurch erreicht, dass glatte Flächen eines Bereichs der Abdeckung und des Rahmens aneinander in Anlage gebracht werden, die schräg ausgebildet sind relativ zu einer Hauptebene der Abdeckung bzw. des Rahmens und somit eine konusförmige bzw. sich verjüngende Anlagefläche bilden. Dadurch kann die Abdeckung nur von einer Seite, d.h. in einer vorgegebenen Einführungsrichtung eingeführt werden und wird von dieser Hauptseite durch ein Bauteil gehalten, so dass sie sich nicht lösen kann. Gleichzeitig sind keine Nuten oder Hinterschnitte, in die die Abdeckung eingesetzt wird, nötig.The invention is based on the idea, a cover for a sight glass as an optional component for a door of a washing and / or drying machine and the corresponding door of a washing and / or drying machine in such a way that, if the cover is not attached, no Gap or similar space is formed in or on the frame, in which dirt or the like can accumulate and is disadvantageous from an aesthetic point of view, so that always the same frame can be used. In particular, the formation of the cover is such that it is held by the special shaping in operative connection with a correspondingly formed area or section of a frame of the door on the same. This is accomplished by abutting smooth surfaces of a portion of the cover and frame that are skewed relative to a major plane of the cover or frame, thus forming a tapered abutment surface. This allows the cover only from one side, ie introduced in a predetermined direction of insertion and is held by this main page by a component so that they can not solve. At the same time, no grooves or undercuts in which the cover is used, necessary.

Erfindungsgemäß weist die Abdeckung zwei Hauptseiten bzw. Hauptflächen und einen äußeren Umfangsbereich auf. Der äußere Umfangsbereich verjüngt sich in einem Bereich einer Anlagefläche. Die Abdeckung ist dazu angepasst, durch Anlage der Anlagefläche an einen komplementär, das heißt entsprechend entgegengesetzt sich verjüngenden, ausgebildeten Bereich eines Rahmens der Tür an dem Rahmen bzw. der Tür gehalten zu werden.According to the invention, the cover has two main sides or main surfaces and an outer peripheral region. The outer peripheral region tapers in a region of a contact surface. The cover is adapted to be held by abutment of the abutment surface to a complementary, that is correspondingly oppositely tapered, formed portion of a frame of the door to the frame or the door.

Bevorzugt liegen sich die Hauptseiten im Wesentlichen gegenüber und ist ein Winkel zwischen einer der Hauptseiten und dem äußeren Umfangsbereich gebildet, der kleiner als 90° ist, d.h. gedachte Verlängerungslinien bzw. -flächen der Hauptseiten und des Umfangsbereich schneiden sich unter einem Winkel, der kleiner als 90° ist, so dass sich der Umfangsbereich insgesamt in einer Richtung verjüngt, die in einem angebrachten Zustand der Abdeckung von dem Schauglas weg verläuft.Preferably, the major sides are substantially opposite each other, and an angle is formed between one of the major sides and the outer circumferential area, which is smaller than 90 °, i.

Fig. 1 zeigt einen Ausschnitt aus einer Schnittansicht einer Tür 10 einer Wasch- und/oder Trockenmaschine gemäß der Erfindung. Man beachte, dass Bauteile, die denen der eingangs in Verbindung mit Fig. 3 und Fig. 4 beschriebenen Tür gemäß dem Stand der Technik entsprechen, durch gleiche Bezugszeichen angegeben sind. Die erfindungsgemäße Tür 10 weist einen Rahmen 14 und ein topfförmiges Schauglas 12 auf. Das Schauglas 12 weist einen flanschförmig ausgebildeten Rand 16 auf. Der Rahmen 14 weist einen Blendring 18 und einen Befestigungsring 22 auf. Der flanschförmige Rand 16 des Schauglases 12 ist zwischen dem Blendring 18 und dem Befestigungsring 22 eingespannt, wobei der Blendring 18 an dem Rand 16 anliegt. Fig. 1 shows a section of a sectional view of a door 10 of a washing and / or drying machine according to the invention. Note that components similar to those initially used in conjunction with FIG. 3 and FIG. 4 described door according to the prior art, are given by the same reference numerals. The door 10 according to the invention has a frame 14 and a pot-shaped sight glass 12. The sight glass 12 has a flange-shaped edge 16. The frame 14 has an aperture ring 18 and a mounting ring 22. The flange-shaped edge 16 of the sight glass 12 is clamped between the aperture ring 18 and the mounting ring 22, wherein the aperture ring 18 rests against the edge 16.

Der Blendring 18 weist in seinem in radialer Richtung gesehenen inneren Umfangsbereich 28 eine Abschrägung 30 auf. Die Abschrägung 30 ist so ausgebildet, dass sie sich in eine Richtung, die der topfförmigen Vertiefung des Schauglases 12 entgegengesetzt ist, verjüngt.The glare ring 18 has a chamfer 30 in its inner circumferential region 28, viewed in the radial direction. The chamfer 30 is formed so as to taper in a direction opposite to the cup-shaped recess of the sight glass 12.

Auch bei der erfindungsgemäßen Tür 10 ist eine Abdeckung 26 vorgesehen. Die Abdeckung 26 weist zwei sich im Wesentlichen parallel gegenüberliegende Hauptseiten 26a, 26b auf. Ihr äußerer Umfangsbereich 32 verjüngt sich in einem Bereich einer Anlagefläche 34. Die Abdeckung 26 liegt mit der Anlagefläche 34 in einem Zustand, in dem die Abdeckung 26 an dem Rahmen 14 angebracht ist, an dem inneren Umfangsbereich 28 bzw. der Abschrägung 30 des Blendring 18 und an einem relativ kleinen innere Umfangsbereich 36 des Rands 16 des Schauglases 12 an, wie in Fig. 1 darstellt ist. Genauer ist der äußere Umfangsbereich 32 gegenüber den Hauptseiten 26a, 26b geneigt, d. h. der Umfangsbereich 32 ist nicht senkrecht bezüglich der Hauptseiten 26a, 26b. Insbesondere weist der äußere Umfangsbereich 32 eine Abschrägung 38 auf, die komplementär zu der Abschrägung 30 ausgebildet ist. Daher ist ein Winkel, der zwischen dem äußeren Umfangsbereich 32 bzw. der Abschrägung 38 und der Hauptseite 26b gebildet ist, kleiner als 90° und der äußere Umfangsbereich 32 verjüngt sich insgesamt in einem bereich der Anlagefläche 34 in einer Richtung, die von dem Schauglas 12 weg verläuft. Dadurch weist die Abdeckung 26 insgesamt allgemein die Form eines Kegelstumpfs auf.Also in the door 10 according to the invention a cover 26 is provided. The cover 26 has two substantially parallel main sides 26a, 26b. Its outer peripheral portion 32 tapers in a region of a contact surface 34. The cover 26 rests with the abutment surface 34 in a state in which the cover 26 is attached to the frame 14, on the inner peripheral portion 28 and the chamfer 30 of the diaphragm ring 18th and at a relatively small inner peripheral portion 36 of the rim 16 of the sight glass 12, as in FIG Fig. 1 represents is. More specifically, the outer peripheral portion 32 is inclined to the main sides 26a, 26b, that is, the peripheral portion 32 is not perpendicular to the main sides 26a, 26b. In particular, the outer peripheral region 32 has a chamfer 38, which is formed complementary to the bevel 30. Therefore, an angle that is is formed between the outer peripheral portion 32 and the chamfer 38 and the main side 26 b, smaller than 90 ° and the outer peripheral portion 32 tapers in total in a region of the abutment surface 34 in a direction which extends away from the sight glass 12. As a result, the cover 26 generally has the shape of a truncated cone.

Zum Anbringen der Abdeckung 26 an der Tür 10 wird die Abdeckung 26 einfach in den Blendring 18 hineingedrückt, so dass zwischen dem Blendring 18 und der Abdeckung 26 eine Art Presspassung gebildet ist. Die Abdeckung 26 ist durch die Form der Abschrägung 30 des Blendrings 18 ohne Befestigungsmittel, wie Schrauben, Nieten, Klebemittel oder dergleichen, gehalten.To attach the cover 26 to the door 10, the cover 26 is simply pressed into the aperture ring 18, so that between the aperture ring 18 and the cover 26 a kind of interference fit is formed. The cover 26 is held by the shape of the chamfer 30 of the blind ring 18 without fasteners such as screws, rivets, adhesive or the like.

Fig. 2 entspricht im Wesentlichen der Darstellung der Fig. 1, wobei die Abdeckung 26 entfernt ist. Wie der Darstellung zu entnehmen ist, steht lediglich der relativ kleine innere Umfangsbereich 36 des Rands 16 des Schauglases 12 über den Blendring 18 hervor, an dem die Abdeckung 26 ansonsten anliegen würde. Ein Spalt wie er bei der obigen Tür gemäß dem Stand der Technik vorhanden ist, ist jedoch durch die erfindungsgemäße Gestaltung nicht mehr gegeben. Dadurch ist dieser kleine innere Umfangsbereich 36 des Rands 16 für Reinigungszwecke zugänglich, so dass eventuelle Ablagerungen an Staub oder dergleichen leicht entfernt werden können. Des Weiteren ist durch die besondere Ausbildung die Möglichkeit gegeben, die Abdeckung 26 auszutauschen. Dazu kann ein Werkzeug erforderlich sein, das zwischen die beiden Abschrägungen 30, 38 gesteckt wird, und die Abdeckung 26 dann über eine Hebelbewegung herausgedrückt wird. Fig. 2 corresponds essentially to the representation of the Fig. 1 with the cover 26 removed. As can be seen from the illustration, only the relatively small inner peripheral region 36 of the edge 16 of the sight glass 12 protrudes beyond the glare ring 18, on which the cover 26 would otherwise rest. A gap as it is present in the above door according to the prior art, however, is no longer given by the inventive design. Thereby, this small inner peripheral portion 36 of the edge 16 is accessible for cleaning purposes, so that any deposits of dust or the like can be easily removed. Furthermore, given the special training, the possibility to replace the cover 26. For this purpose, a tool may be required, which is inserted between the two bevels 30, 38, and the cover 26 is then pushed out via a lever movement.

Durch die besondere Formgebung des Rahmens und der Abdeckung ist es beispielsweise möglich, Türen für eine Wasch- und/oder Trockenmaschine mit immer ein und denselben Rahmen zu verwenden bzw. herzustellen, unabhängig davon, ob eine Abdeckung angebracht werden soll, ohne dass dekorative bzw. ästhetische und reinigungstechnische Nachteile in Kauf genommen werden müssen.Due to the special shape of the frame and the cover, it is possible, for example, to use doors for a washing and / or drying machine with always one and the same frame, regardless of whether a cover is to be attached without decorative or aesthetic and cleaning disadvantages must be taken into account.

Die Form der Abschrägung ist dabei nicht auf eine Art lineare Kante, wie sie in den Figuren zu sehen ist, beschränkt. Die Form kann nach Bedarf gewählt werden. Insbesondere ist eine abgerundete, gebogene, gewellte, mit Rillen oder Noppen versehene Form denkbar. Der äußere Umfangsbereich kann von zumindest einer der Hauptseiten vorstehend ausgebildet sein. Die Abdeckung kann allgemein in einer Draufsicht gesehen kreisförmig bzw. scheibenförmig, quadratisch, rechteckig trapezförmig oder konvex sein.The shape of the chamfer is not limited to a kind of linear edge, as can be seen in the figures. The shape can be chosen as needed. In particular, a rounded, curved, corrugated, grooved or nubbed shape is conceivable. The outer peripheral region may be formed protruding from at least one of the main sides. The Cover may generally be circular, disc-shaped, square, rectangular, trapezoidal or convex when viewed in plan.
