Description

Die Erfindung betrifft eine Wäschebehandlungsmaschine insbesondere Wäschetrockner mit einer in einem Gehäuse drehbar gelagerten Trommel, welche an der Gehäusefrontseite eine Beschickungsöffnung aufweist, die mit einer Tür verschließbar ist, wobei die Tür aus einem mittels eines Scharniers schwenkbaren und mittels eines Schließklobens verschließbaren Türträgering besteht an dessen zur Innenseite weisenden Rand der Glasflansch eines topfförmigen Schauglases befestigt ist, auf dem wiederum ein den Glasflanschbereich abdeckender Blendring angeordnet ist.The invention relates to a laundry treatment machine, in particular tumble dryer with a rotatably mounted in a housing drum, which has a loading opening on the housing front side, which is closable with a door, wherein the door consists of a pivotable by means of a hinge and closable by means of a closing door carrier is at the Inside edge facing the glass flange of a pot-shaped sight glass is fixed, on which in turn a Glasflanschbereich covering Blendring is arranged.

Aus dem Stand der Technik sind Wäschetrockner mit Beschickungsöffnung an der Frontseite des Maschinengehäuses bekannt. Die Beschickungsöffnung wird mit einer Tür verschlossen, welche mittels eines Scharniers schwenkbar an der Gehäusefront gelagert ist. Gegenüber dem Scharnier ist ein Schließkloben angeordnet, der in die Gehäusefrontseite eingreift und dort verriegelt wird. Die Tür als solches besteht hierbei aus einem ringförmigen Türträger, der einen als Schauglas ausgebildeten Topf aufnimmt und an diesem befestigt ist. An dem ringförmigen Türträger ist von außen und von innen jeweils ein Türblendring vorgesehen, der den Türträgerring mit den Scharnieren und dem Schließkloben abdeckt.Clothes dryers with a charging opening on the front side of the machine housing are known from the prior art. The loading opening is closed by a door, which is mounted by means of a hinge pivotally mounted on the housing front. Opposite the hinge a locking pin is arranged, which engages in the housing front side and is locked there. The door as such here consists of an annular door support, which receives a trained as a sight glass pot and is attached to this. On the annular door support a door aperture ring is provided from the outside and from the inside, which covers the door support ring with the hinges and the locking bolt.

Nach den Designvorgaben wird gefordert, dass zwischen dem Glasflansch und der inneren Türblende ein Abstand im Millimeterbereich einzuhalten ist. Aufgrund der großen Glasdurchmessertoleranzen ergibt sich immer eine konstruktive Fuge zwischen Glas und Blende von mindestens ca. 1 Millimeter. Aus der DE 10 2005 023 445 A1 ist eine Tür für einen Wäschetrockner bekannt, bei dem eine solche Fuge zwischen einem Rahmen und der Glasscheibe mit einer angeformten Dichtung, welche sich lippenartig an der Innenseite der Glasscheibe anschmiegt, überdeckt wird. Wird die Fuge offen gelassen, ergeben sich folgende Nachteile, so können einerseits Flusen in den Hohlraum eindringen und andererseits können aber auch Kondensattropfen in den Hohlraum eindringen, wobei das Innere der Türkonstruktion hierbei auch sichtbar ist. Um diese Nachteile zu beheben, ist es erforderlich, dass eine Dichtung mit Sichtschutz einzusetzen ist. Die bekannte Lösung ist hier das Einsetzen eines Dichtprofils, welches auf der inneren Türblende aufgesteckt wird. Als Sichtschutz wird zudem ein ringförmiges Kunststoffbauteil eingesetzt. Alternativ könnte hierfür auch ein Zweikomponentenbauteil eingesetzt werden. Die Hartschaumkomponente dieses Bauteils dient hierbei als Träger und Sichtschutz, wobei eine angespritzte Weichkomponente die Dichtfunktion ausübt. Bei all diesen möglichen Lösungen wird es als nachteilig angesehen, dass der Einsatz von zwei Bauteilen erforderlich ist, was insbesondere die Kosten erhöht und eine aufwendige Montage mit sich bringt.According to the design specifications, it is required that a distance in the millimeter range is to be maintained between the glass flange and the inner door panel. Due to the large glass diameter tolerances always results in a constructive joint between glass and aperture of at least about 1 millimeter. From the DE 10 2005 023 445 A1 For example, a door for a tumble dryer is known in which such a joint is covered between a frame and the glass pane with a molded-on gasket, which clings like a lip to the inside of the glass pane. If the joint is left open, the following disadvantages result, on the one hand lint can penetrate into the cavity and on the other hand, but also drops of condensation can penetrate into the cavity, wherein the interior of the door construction is also visible. To overcome these disadvantages, it is necessary to use a seal with privacy. The known solution here is the onset of a sealing profile, which is plugged onto the inner door panel. As a visual protection also an annular plastic component is used. Alternatively, this could also be a two-component component can be used. The hard foam component of this component serves as a support and visual protection, with a molded soft component exerts the sealing function. With all these possible solutions, it is considered disadvantageous that the use of two components is required, which in particular increases the cost and brings a complex assembly with it.

Der Erfindung stellt sich somit das Problem eine geeignete Fügetechnik sowie ein Herstellungsverfahren für den Türblendring am ringförmigen Türträger bereitzustellen, welche einen kostengünstigen Verschluss der Schauglasanschlussfuge bezüglich Flusen, Kondensat und Durchsichtigkeit bereitstellt.The invention thus presents the problem of providing a suitable joining technique and a method of manufacturing the door panel ring on the annular door support, which provides a cost-effective closure of the sight glass connection joint with respect to lint, condensate and transparency.

Erfindungsgemäß wird dieses Problem durch ein mit den Merkmalen des Patentanspruchs 1 und 9 gelöst. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung ergeben sich aus den nachfolgenden Unteransprüchen.According to the invention this problem is solved by a with the features of claim 1 and 9. Advantageous embodiments and further developments of the invention will become apparent from the following subclaims.

Die mit der Erfindung erreichten Vorteile bestehen darin, dass auf das Schauglas mit einer robotergeführten Düse ein flüssiger Polyurethan-Schaum aufgebracht wird. Dieser härtet über einen Aufschäumprozess aus und erhält dabei seine ausreichende Elastizität, die die geforderte Dichtigkeit bereitstellt. Die innere Türblende wird dann von oben aufgesetzt und gefügt, so dass im Zusammenspiel des aufgetragenen Polyurethan-Schaums mit der inneren Kante der Türblende eine Dichtung gegenüber Flusen und Kondensat vorhanden ist. Der Schaum als solches bildet hierbei auch den geforderten Sichtschutz. Der aufgetragene Schaum weist hierbei zwei wesentliche Vorteile auf, und zwar liegt er einmal direkt am Schauglas an, weil er direkt auf die Glasoberfläche aufgespritzt wird, und er vereint die Funktionen Sichtschutz und Dichtung in einem Bauteil. Somit gibt es auch keine weitere optisch störende Fuge bzw. Sichtkante. Bei Kontakt mit Wasser löst sich der Schaum nicht vom Glas ab. Die neue Lösung ist hierbei nicht auf die Verwendung von Polyurethan als Basis beschränkt. Andere Materialschäume können analog der obigen Beschreibung eingesetzt werden.The advantages achieved by the invention are that a liquid polyurethane foam is applied to the sight glass with a robot-guided nozzle. This hardens through a foaming process while maintaining its sufficient elasticity, which provides the required tightness. The inner door panel is then placed from above and joined, so that in the interaction of the applied polyurethane foam with the inner edge of the door panel a seal against lint and condensate is present. The foam as such also forms the required privacy. The applied foam has two major advantages, namely, it rests directly on the sight glass, because it is sprayed directly onto the glass surface, and it combines the functions of privacy and seal in one component. Thus there is no further optically disturbing joint or visible edge. On contact with water, the foam does not detach from the glass. The new solution is not limited to the use of polyurethane as a base. Other material foams can be used analogously to the above description.

Weitere Vorteile ergeben sich dadurch, dass mit der erfindungsgemäßen Lösung Kosten dahingehend eingespart werden, weil zusätzliche Bauteile am Glasflansch nicht mehr erforderlich sind, wobei die Dichtung maschinell aufgetragen werden kann, so dass dadurch insbesondere Montagekosten eingespart werden.Further advantages result from the fact that costs are saved with the solution according to the invention because additional components on the glass flange are no longer required, wherein the seal can be applied by machine, thereby saving assembly costs in particular.

Gemäß der Erfindung ist am Glasflanschbereich ein schaumartiger Ringstreifen als Flusen- und Kondensatdichtung vorgesehen, der im zusammengefügten Zustand des Blendringes überdeckt ist. Hierbei wird der schaumartige Ringstreifen mittels einer Düse in flüssiger Form auf das Glas aufgetragen. Nach einer vorteilhaften Ausgestaltung besteht der schaumartige Ringstreifen aus einer Polyurethanbeschichtung. Der Ringstreifen als solches liegt hierbei mit seiner vorderen Dichtkante am Glasflanschschenkel an, wobei er mit seiner hinteren umlaufenden Dichtkante einen überwölbten Ringansatz bildet, an dem im zusammengefügten Zustand der Blendring dichtend anliegt. Somit ergibt sich eine Dichtung, die einerseits einen optischen Verschluss zum Blendring bereitstellt, wobei andererseits die dichtende Funktion gewährleistet wird.According to the invention, a foam-like ring strip is provided as a lint and condensate seal on Glasflanschbereich, which is covered in the assembled state of the blend ring. Here, the foam-like ring strip is applied by means of a nozzle in liquid form on the glass. According to an advantageous embodiment, the foam-like ring strip consists of a polyurethane coating. The ring strip as such is in this case with its front sealing edge on Glasflanschschenkel, where it forms with its rear circumferential sealing edge a vaulted annular shoulder on which sealingly rests in the assembled state of the glare ring. This results in a seal which on the one hand provides an optical shutter to the blind ring, on the other hand, the sealing function is ensured.

Nach einer vorteilhaften Ausgestaltung der Erfindung umfasst der Blendring im Wesentlichen eine U-Form, dessen Basis die Breite des schaumartigen Ringstreifens überdeckt. Dabei liegt der vordere Schenkel des U-förmigen Blendringes an dem Glasflanschschenkel stützend an, wobei der hintere Schenkel des U-förmigen Blendringes an dem überwölbten umlaufenden Ringansatz des schaumartigen Ringstreifens dichtend anliegt. Nach einer zweckmäßigen Ausgestaltung ist an der Unterseite der Basis ein umlaufender Blendstreifensteg angeformt, der in zusammengefügten Zustand des Blendringes an dem Türträgerring ebenfalls anliegt.According to an advantageous embodiment of the invention, the glare ring substantially comprises a U-shape, the base of which covers the width of the foam-like ring stripe. It lies the front leg of the U-shaped aperture ring supporting on the Glasflanschschenkel, wherein the rear leg of the U-shaped aperture ring sealingly abuts the vaulted circumferential annular shoulder of the foam-like ring strip. According to an expedient embodiment, a circumferential Blendstreifensteg is formed on the underside of the base, which also rests in the assembled state of the blend ring on the door support ring.

Das Problem wird ebenfalls durch ein Verfahren zur Herstellung einer Dichtung an einer Tür einer Wäschebehandlungsmaschine, insbesondere eines Wäschetrockners gelöst. Der Wäschetrockner weist hierbei mit einer in einem Gehäuse drehbar gelagerten Trommel eine Beschickungsöffnung an der Frontseite auf, die mit einer Tür verschlossen wird, wobei die Tür aus einem mittels eines Scharniers schwenkbaren und mittels eines Schließklobens verschließbaren Türträgerring besteht, an dessen zur Innenseite weisenden Rand der Glasflansch eines topfförmigen Schauglases befestigt wird auf dem wiederum ein den Glasflanschbereich abdeckender und dichtender Blendring angesetzt wird. Erfindungsgemäß wird hierzu nach dem Verfahren vorgeschlagen, dass am Glasflanschbereich ein schaumartiger Ringstreifen als Flusen- und Kondensatdichtung mittels einer robotergeführten Düse in flüssiger Form aufgetragen wird, bevor der den Ringstreifen überdeckende Blendring am Türträgerring angesetzt wird. Der schaumartige Ringstreifen besteht hierbei aus einer Polyurethan-Beschichtung, wobei der sich beim Aufschäumprozess bildende Ringstreifen mit seiner vorderen Dichtringkante am Glasflanschschenkel anliegt und mit seiner hinteren umlaufenden Dichtkante einen überwölbten Ringansatz bildet.The problem is also solved by a method for producing a seal on a door of a laundry treatment machine, in particular a clothes dryer. The dryer has in this case with a rotatably mounted in a housing drum on a loading opening on the front side, which is closed by a door, wherein the door consists of a pivotable by means of a hinge and closable by means of a closing door carrier ring, at its inner edge facing the Glass flange of a pot-shaped sight glass is fixed on the turn a glass flange is covered and sealing sealing ring is attached. According to the invention, it is proposed according to the method that a foam-like ring strip is applied as a lint and condensate seal on the glass flange area by means of a robot-guided nozzle in liquid form, before the masking ring covering the ring strip is attached to the door carrier ring. The foam-like ring strip here consists of a polyurethane coating, wherein the ring strip forming during the foaming process rests with its front sealing ring edge on the glass flange leg and forms a vaulted annular projection with its rear circumferential sealing edge.
