Description

Die Erfindung betrifft eine Wäschebehandlungsmaschine wie Waschmaschine oder Wäschetrockner mit einer in einem Gehäuse drehbar gelagerten Trommel, einer mit einer Tür verschließbaren Beschickungsöffnung sowie einer in der Frontwand des Gehäuses angeordneten Revisionsklappe für den Zugang eines im Gehäusebereich untergebrachten Filtereinsatzes.The invention relates to a laundry treatment machine such as a washing machine or tumble dryer with a drum rotatably mounted in a housing, a closable with a door feed opening and arranged in the front wall of the housing inspection flap for access to a housed in the housing area filter insert.

Aus dem Stand der Technik ist eine Wäschebehandlungsmaschine, und hier insbesondere ein Wäschetrockner gemäß der EP 2107155 A2 bekannt. Bei diesem bekannten Wäschetrockner ist an der Frontseite eine Revisionsklappe vorgesehen hinter der ein zugänglicher Filtereinsatz im Strömungskanal für die Prozessluft eingesetzt werden kann. Der Filtereinsatz besteht aus einem Filterblock zur Filtrierung von Staub, wobei der Filterblock als ein separates Einsatzteil selbstdichtend in den Strömungskanal eingesetzt wird. Bei einer Waschmaschine befindet sich hinter der Revisionsklappe ebenfalls eine Filteranordnung, mit der Fein- und Grobteile aus der Waschlauge herausgefiltert werden können. Als nachteilig bei den beschriebenen Wäschebehandlungsmaschinen mit angeordneten Revisionsklappen in der Frontseite wird es angesehen, dass diese in der Gehäusefrontfläche optisch derart eingebunden sind, dass diese nur noch in Andeutung ihres Randes in der Fläche erkennbar sind. Um die Revisionsklappe zu betätigen, bedarf es hier eines Werkzeugs, mit dem die selbstklemmende Revisionsklappe aus der Frontwand heraus gehebelt werden kann, um an die entsprechende hinter der Gehäusewand angeordnete Filtereinrichtungen zu gelangen. Es ist daher erforderlich, dass bei den aus dem Stand der Technik bekannten Wäschebehandlungsmaschinen zur Betätigung der Revisionsklappe ein Werkzeug benötigt wird.From the prior art is a laundry treatment machine, and in particular a tumble dryer according to the EP 2107155 A2 known. In this known tumble dryer, an inspection flap is provided on the front side behind which an accessible filter insert in the flow channel for the process air can be used. The filter element consists of a filter block for filtering dust, wherein the filter block is used as a separate insert part self-sealing in the flow channel. In the case of a washing machine, behind the access flap, there is also a filter arrangement with which fine and coarse particles can be filtered out of the wash liquor. A disadvantage of the described laundry treatment machines with arranged inspection flaps in the front, it is considered that they are optically integrated in the housing front surface so that they are recognizable only in hint of their edge in the surface. In order to operate the access panel, it requires a tool here, with which the self-clamping access panel can be levered out of the front wall in order to reach the corresponding arranged behind the housing wall filter devices. It is therefore necessary that a tool is needed in the known from the prior art laundry treatment machines for actuating the access door.

Auch aus der EP 2 309 053 A1 ist eine Wäschebehandlungsmaschine der eingangs genannten Art bekannt.Also from the EP 2 309 053 A1 a laundry treatment machine of the type mentioned is known.

Die KR 10 2009 0118663 A1 offenbart einen Wäschetrockner mit einer Revisionsklappe, welche sich auf Druck selbsttätig öffnet.The KR 10 2009 0118663 A1 discloses a clothes dryer with a revision flap which opens automatically upon pressure.

In der WO 2005/090669 A2 ist eine Wäschebehandlungsmaschine beschrieben, bei der die Revisionsklappe mit einer Griffmulde ausgestattet ist.In the WO 2005/090669 A2 is a laundry treatment machine described in which the access door is equipped with a recessed grip.

Erfindungsgemäß weist hierzu die Revisionsklappe einen in der Fläche plan liegenden bzw. bündig liegenden Taster auf, der eine vom Taster verdeckte Öffnung in der Revisionsklappe zum Eingreifen für das Verschwenken der Revisionsklappe freigibt. Soll nun die Revisionsklappe geöffnet werden, so besteht die Möglichkeit, den Taster mit einem Finger einfach in die Fläche der Revisionsklappe hineinzudrücken, sodass dadurch ein Öffnungsrand freigegeben wird, der zur Betätigung der Revisionsklappe dient. Dabei schließt der Taster unter Wirkung einer Feder die Öffnung selbsttätig, wenn der Finger aus der Öffnung wieder herausgezogen wird. Wird die Klappe also wieder in den Öffnungsquerschnitt eingesetzt und der Taster wieder freigegeben, so schließt der Taster die Öffnung selbsttätig.According to the invention for this purpose, the inspection flap on a plane lying flat or lying on the button, which releases a hidden by the button opening in the access door to engage for pivoting the access door. If now the inspection flap to be opened, it is possible to simply press the button with a finger into the surface of the inspection flap, thereby an opening edge is released, which is used to operate the access panel. The button closes under the action of a spring, the opening automatically when the finger is pulled out of the opening again. If the flap is thus re-inserted into the opening cross-section and the button released again, the button closes the opening automatically.

In Weiterbildung der Erfindung ist der Taster als Hebelelement an der Rückseite der Revisionsklappe schwenkbar gelagert. Mit dem Hebelelement wirkt ein Blattfederstreifen zusammen. Dabei umfasst das Hebelelement zwei Hebel, die in parallel angeordneten Lagern an der Rückseite der Revisionsklappe gelagert sind. Zwischen den beiden gelagerten Hebeln ist der Blattfederstreifen angeordnet. Der Blattfederstreifen liegt dabei mit seinem unteren Ende an der Rückwand der Revisionsklappe an, wobei das obere Ende des Blattfederstreifens an dem die Öffnung verschließenden Taster fixiert ist. In einer Ausführung der Erfindung ist das untere Ende des Blattfederstreifens in einer an der Rückwand angeordneten Halterung clipsbar. Die Öffnung in der Revisionsklappe ist kreisrund ausgebildet, in der der flach, topfartig ausgebildete Taster bündig im Verschlusszustand liegt. Andere Formen der Öffnung sind je nach optischen Gegebenheiten auch möglich, wie oval oder mehreckig. Der topfartig ausgebildete Taster weist einen Kragenrand auf, der sich in der Verschlusslage rückwärtig an den Rand der Öffnung anlegt. Nach einer besonders vorteilhaften Ausgestaltung der Erfindung weist der topfartig ausgebildete Taster zur Gehäuseaußenseite eine leichte konkave Wölbung auf.In a further development of the invention, the button is pivotally mounted as a lever element on the back of the inspection flap. With the lever element a leaf spring strip acts together. In this case, the lever element comprises two levers which are mounted in parallel bearings on the back of the access door. Between the two levers mounted the leaf spring strip is arranged. The leaf spring strip lies with its lower end against the rear wall of the inspection flap, the upper end of the leaf spring strip being fixed to the button closing the opening. In one embodiment of the invention, the lower end of the leaf spring strip can be clipped in a holder arranged on the rear wall. The opening in the inspection flap is circular, in which the flat, pot-shaped button is flush in the closed state. Other forms of opening are also possible depending on the optical conditions, such as oval or polygonal. The pot-shaped button points a collar edge, which rests in the closed position backwards to the edge of the opening. According to a particularly advantageous embodiment of the invention, the pot-shaped button on the outside of the housing has a slight concave curvature.

In einer zweckmäßigen Weiterbildung ist die Anlage für das freie Ende der Feder als Steg zur Bereitstellung einer Steuerkurve ausgebildet ist. Die Steuerkurve des Stegendes ist hierbei die dazu eingerichtet, die Rückstellkraft des Tasters in Abhängigkeit des Öffnungswinkels zu beeinflussen, da beim Verändern des Öffnungswinkels das freie Federende entlang an der Steuerkurve gleitet. Zweckmäßigerweise ist die Steuerkurve so ausgelegt, dass sich der Kraftaufwand mit größer werdendem Öffnungswinkel nicht so stark vergrößert bzw. dass die Rückstellkraft bei geschlossenem Taster größer ist, als bei geöffnetem Taster. Damit wird einerseits ein sicherer und zuverlässiger Verschluss der Betätigungsöffnung sichergestellt und andererseits eine bequeme und einfache Handhabung für den Bediener bereitgestellt, da nach dem Öffnen des Tasters keine hohen Rückstellkräfte auf den Finger des Bedieners wirken.In an expedient development, the system for the free end of the spring is designed as a web for providing a control cam. The cam of the web end is in this case adapted to influence the restoring force of the probe as a function of the opening angle, since when changing the opening angle, the free spring end slides along the control curve. Conveniently, the cam is designed so that the force is not increased so much with increasing opening angle or that the restoring force is greater when the button is closed, than when the button is open. This ensures, on the one hand, a secure and reliable closure of the actuating opening and, on the other hand, provides a convenient and simple handling for the operator since after opening the button no high restoring forces act on the operator's finger.

Die Öffnung 9 ist hierbei in der Revisionsklappe 5 kreisrund ausgebildet, in der der flach, topfartig ausgebildete Taster 8 bündig im Verschlusszustand liegt, wie dies aus der Figur 1 und der Figur 3 zu erkennen ist. Die entsprechende Situation ist auch in der Figur 7 zu erkennen, wo der Taster von der Rückseite her dargestellt ist. Figur 4 und 6 zeigen insbesondere die Ausgestaltung des Tasters 8, wobei dieser topfartig ausgebildet ist und einen Kragenrand 19 aufweist, der sich in der Verschlusslage, Figur 4, rückwärtig an den Rand der Öffnung 9 anlegt. Dabei weist der topfartig ausgebildete Taster 8 zur Gehäuseaußenseite hin eine leichte konkave Wölbung 20 auf, wie diese insbesondere in der Figur 4, aber auch in der Figur 6 in der geschnittenen Darstellung erkennbar ist. Es versteht sich nun von selbst, dass aufgrund des erfindungsgemäßen Tasters 8 hier eine einfache werkzeuglose Öffnung der Revisionsklappe 5 erfolgen kann. Hierzu bedarf es nur den Taster 8 mit einem leichten Fingerdruck nach innen zu drücken, sodass der Öffnungsrand der Öffnung 9 hier die Möglichkeit bereitstellt, hinter den rückwärtigen Bereich der Revisionsklappe 5 zu greifen, sodass ein Angriffspunkt geschaffen wird, um die Revisionsklappe 5, die mittels Scharnieren 21 an der Frontwand 4 angelenkt ist, heraus zu schwenken. Ist der Filtereinsatz 6 gewechselt oder gereinigt, so wird in einfacher Weise die Revisionsklappe 5 an der Scharnieranordnung 21 hochgeschwenkt und über die Rastfedern 22 dann wieder an der Frontwand 4 festgelegt.According to an advantageous embodiment, in this case the lower end of the leaf spring strip 11 can be clipped in a holder 18 arranged on the rear side 16. The opening 9 is in this case formed circular in the inspection flap 5, in which the flat, pot-shaped button 8 is flush in the closed state, as shown in FIG. 1 and the FIG. 3 can be seen. The corresponding Situation is also in the FIG. 7 to recognize where the button is shown from the back. FIGS. 4 and 6 show in particular the design of the button 8, wherein this is pot-shaped and has a collar edge 19, which is in the closed position, FIG. 4 , rearwardly abuts the edge of the opening 9. In this case, the pot-shaped button 8 to the outside of the housing towards a slight concave curvature 20, as this particular in the FIG. 4 but also in the FIG. 6 can be seen in the sectional view. It goes without saying that a simple tool-free opening of the access door 5 can be done here due to the probe 8 according to the invention here. For this purpose, it only requires the button 8 with a light finger pressure to press inwards, so that the opening edge of the opening 9 here provides the opportunity to reach behind the rear area of the access door 5, so that a point is created to the inspection flap 5, by means of Hinges 21 is hinged to the front wall 4, to swing out. If the filter insert 6 is changed or cleaned, then the inspection flap 5 is pivoted upwards in a simple manner on the hinge arrangement 21 and then fixed again on the front wall 4 via the latching springs 22.
