Abstract

The opening (2) of the door frame (3) for the frontal access opening has, at least approximately, the shape of a rectangle, in which the sides (9, 10) form outwardly curved chords of an imaginary circumcircle around the opening (2) and the corners (11, 16) have a curvature which is constant in relation to the side lines (9, 10) but greater in comparison with them. As a result, the opening of the door frame can be considerably enlarged and nevertheless a relatively high border with the bottom edge of the door frame can remain between the drum interior and the exterior. The risk of items of washing falling out of the drum when the door is open is thereby minimised. <IMAGE>

Description

Die Erfindung geht aus von, einem Wäschetrockner mit einer um eine mindestens, annähernd waagerechte Achse drehbar gelagerten Wäschetrommel, die im Stirnboden eine kreisrunde Beschickungsöffnung aufweist, die innen an einem frontseitigen Türrahmen des Gehäuses lagert und mit einer nahe dem Türrahmen schwenkbar gelagerten Tür verschließbar ist.The invention is based on, a tumble dryer with a laundry drum rotatably mounted about an at least approximately horizontal axis, which has a circular loading opening in the front floor, which is mounted on the inside of a front door frame of the housing and can be closed with a door pivotably mounted near the door frame.

Ein derartiger Wäschetrockner ist aus dem deutschen Gebrauchsmuster 81 30 602 bekannt. Der Türrahmen an der gehäuseseitigen Beschikkungsöffnung ist kreisrund geformt und nimmt einen die Beschickungsöffnung ausfüllenden Topf auf, der an der Innenseite der Türplatte symmetrisch angebracht ist. Die Tür ist seitlich schwenkbar gelagert und kann von Rechts- auf Linksanschlag umgesetzt werden. Dazu ist lediglich das Scharnier von der Gehäuse-Vorderwand zu lösen, die Türplatte zusammen mit dem Topf um 180° zu drehen und das Scharnier auf der anderen Seite der Beschickungsöffnung an der vorderwand des Trockner-Gehäuses wieder zu montieren. Dazu sind an der Montagestelle selbstverständlich entsprechende Befestigungsbohrungen vorzusehen.Such a tumble dryer is known from German utility model 81 30 602. The door frame on the housing-side loading opening is circular in shape and receives a pot filling the loading opening, which is attached symmetrically to the inside of the door panel. The door is pivoted to the side and can be moved from right to left hinged. All you have to do is loosen the hinge from the front wall of the housing, turn the door plate together with the pan through 180 ° and reassemble the hinge on the other side of the loading opening on the front wall of the dryer housing. Appropriate mounting holes must of course be provided for this at the assembly point.

Zur Verbesserung des Zugangs zur hinter der Beschickungsöffnung liegenden Wäschetrommel ist es bekannt, die kreisrunde Öffnung zu vergrößern. Einer beliebigen Vergrößerung steht jedoch die über der Beschickungsöffnung in der Vorderwand des Wäschetrockners angebrachte Bedienungsblende entgegen. Bei einigen im Markt befindlichen Wäschetrocknern sind daher die kreisrunden Beschickungsöffnungen in ihrem oberen Teil segmentartig abgeschnitten und mit einem entsprechend geformten Topf der Tür ausgefüllt. An der entlang der Sehne verlaufenden Mantelfläche des Topfes ist dann die Einstecköffnung für einen Filterrahmen angebracht, der innerhalb des Topfes von den Endpunkten der Sehne ab senkrecht nach unten geführt ist.To improve access to the laundry drum located behind the loading opening, it is known to enlarge the circular opening. Any enlargement, however, is opposed by the control panel attached above the loading opening in the front wall of the tumble dryer. In some tumble dryers on the market, the circular loading openings are cut off in segments in their upper part and filled with a suitably shaped pot of the door. The insertion opening for a filter frame is then provided on the lateral surface of the pot running along the chord, which is guided vertically downward within the pot from the end points of the chord.

Seitlich der Führungen gehen größere Raumsegmente für. die Nutzung durch das Filter verloren, so daß die insgesamt zur
Verfügung stehende Filterfläche eine verhältnismäßig hohe Durchströmgeschwindigkeit bedingt, die in erhöhtem Maße Flusen durch das Sieb zieht, die bei geringerer Durchströmgeschwindigkeit am Sieb aufgehalten werden könnten. Ferner erlaubt die bekannte Form der vergrößerten Beschickungsöffnung das Umsetzen des Türanschlags nur dadurch, daß auch die an der Tür befestigten Scharnierteile an die andere Türkante umgesetzt werden. Des weiteren hat sich im praktischen Gebrauch der vergrößerten Beschickungsöffnung die tiefe Unterkante, die bereits nahe der tiefsten Trommel-Innenfläche angeordnet ist, als nachteilig erwiesen, weil sowohl beim Einladen eines größeren Wäschepostens als auch beim Türöffnen nach abgeschlossenen Trocknungsvorgang einzelne Wäschestücke wieder zurückfallen bzw. vorzeitig aus der Trommel herausfallen. Insbesondere bei Wäschetrocknern, die mit einer die ganze Gehäusebreite überdeckenden und tief bis in Bodennähe sich erstreckenden Vortür ausgestattet sind, kann vor dem Öffnen der Tür kein Wäschekorb unter die Beschickungsöffnung gestellt werden, um herausfallende Wäschestücke etwa aufzufangen.
Larger room segments go to the side of the guides. the use lost by the filter, so that the total for
Available filter area requires a relatively high flow rate, which draws fluff through the sieve to an increased extent, which could be stopped on the sieve at a lower flow rate. Furthermore, the known shape of the enlarged loading opening allows the door stop to be moved only in that the hinge parts attached to the door are also moved to the other door edge. Furthermore, in practical use of the enlarged loading opening, the deep lower edge, which is already located near the deepest inner drum surface, has proven to be disadvantageous because both items of laundry fall back or prematurely both when loading a larger item of laundry and when opening the door after the drying process has been completed fall out of the drum. Particularly in the case of tumble dryers which are equipped with a front door which covers the entire width of the housing and extends deep to the ground, it is not possible to place a laundry basket under the loading opening before the door is opened, in order to catch laundry items that fall out.

Der Erfindung liegt die Aufgabe zugrunde, einen Wäschetrockner der eingangs genannten Art so auszubilden, daß einerseits ein Türanschlag-wechsel durch Drehen der Tür um 180 möglich ist, damit der Montageaufwand beim Türanschlag-wechsel gering bleiben kann, daß des weiteren die installierbare Siebfläche vergrößert und damit die Durchströmungsgeschwindigkeit verringert werden kann und daß schließlich die Unterkante der Beschickungsöffnung kaum niedriger angeordnet ist als bei früheren, nicht vergrößerten Beschickungsöffnungen.The invention has for its object to provide a tumble dryer of the type mentioned in such a way that on the one hand a door stop change is possible by rotating the door by 180, so that the assembly effort when changing the door stop can remain low, that the screen area that can be installed is also enlarged and so that the flow rate can be reduced and that finally the lower edge of the loading opening is hardly arranged lower than with earlier, not enlarged loading openings.

Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß die Öffnung des Türrahmens eine einem Rechteck mindestens angenäherte Form aufweist, in der die Seiten nach außen gekrümmte Sehnen eines gedachten Umkreises um die Öffnung bilden und die Ecken eine zu den Seitenlinien stetige, im Vergleich dazu aber stärkere Krümmung aufweisen. Die Form der Beschickungsöffnung ähnelt dadurch stark der Form eines Fernseh-Bildschirmes und bietet erheblich mehr Fläche zur Installation eines Flusenfilters. Fast die gesamte Breite und wie beim Stand der Technik die gesamte Höhe stehen dieser Filterfläche zur Verfügung. Die Unterkante der Beschickungsöffnung bildet auch gegenüber der Wäschetrommel eine nach außen gekrümmte Sehne, deren Bogenhöhe zur inneren Kontur des Trommelmantels noch genügend grob ist, um zu verhindern, daß in die Trommel geladene Wäschestücke ohne weiteres aus der geöffneten Beschickungsöffnung fallen. Die Form der Beschickungsöffnung, die grundsätzlich zu ihren senkrechten und waagerechten Mittellinien symmetrisch ausgebildet ist, erhält weiterhin die vorteilhafte Möglichkeit, den Türanschlag mit geringem Montageaufwand wie beim deutschen Gebrauchsmuster 81 30 602 zu wechseln. Entsprechend wird dann der jeweils von oben in den rechteckigen, in die Beschickungsöffnung eindringenden Körper einsteckbare Filterrahmen und seine im Körper angeordnete Führung so ausgebildet, daß er in jeder Türanschlag-Version von oben einsteckbar ist und sicher gehalten wird.According to the invention this object is achieved in that the opening of the door frame has a shape at least approximating a rectangle, in which the sides form outwardly curved chords of an imaginary circumference around the opening and the corners have a curvature which is continuous to the side lines, but stronger in comparison thereto exhibit. The shape of the loading opening is therefore very similar to the shape of a television screen and offers considerably more space for installing a lint filter. Almost the entire width and, as in the prior art, the entire height are available to this filter area. The lower edge of the loading opening also forms an outwardly curved chord with respect to the laundry drum, the bow height of the inner contour of the drum shell being still sufficiently large to prevent laundry items loaded into the drum from falling easily out of the opened loading opening. The shape of the loading opening, which is basically symmetrical with respect to its vertical and horizontal center lines, also has the advantageous possibility of changing the door stop with little installation effort, as in the German utility model 81 30 602. Correspondingly, the filter frame which can be inserted into the rectangular body penetrating the loading opening and its guide arranged in the body is designed in such a way that it can be inserted from above in every door stop version and is held securely.

Anhand der in der Zeichnung dargestellten Ausführungsbeispiele ist die Erfindung nachstehend erläutert. Es zeigen:

  • Fig. 1 eine perspektivische Frontansicht eines erfindungsgemäß ausgestatteten Wäschetrockners mit geöffneter Beschickungstür,
  • Fig. 2 eine mögliche Ausgestaltung der Kontur der Öffnung des Türrahmens im Vergleich zu vergrößerten Beschikkungsöffnungen, die bei am Markt befindlichen Wäschetrocknern verwendet werden und
  • Fig. 3 eine in Eckenbereich anders gestaltete Ausführungsforn des erfindungsgemmäßen Türrahmens.
The invention is explained below on the basis of the exemplary embodiments illustrated in the drawing. Show it:
  • Fig. 1 is a front perspective view of an equipped according to the invention Tumble dryer with open loading door,
  • Fig. 2 shows a possible configuration of the contour of the opening of the door frame compared to enlarged loading openings that are used in clothes dryers on the market and
  • 3 shows an embodiment of the door frame according to the invention which is designed differently in the corner region.

Der in Fig. 1 dargestellte Wäschetrockner hat an der Frontseite im oberen Bereich eine Bedienungsblende 1 und eine darunter angeordnete Beschickungsöffnung 2, die von einem Türrahmen 3 eingefaßt ist. Der Türrahmen bildet an der Innenseite ein kreisrundes Lagerschild (nicht dargestellt) für die kreisrunde Beschickungsöffnung der Trommel 4. Rechts der Beschickungsöffnung 2 ist die Tür 5 mittels zweier Scharniere 6 schwenkbar gelagert. Sie trägt auf der Innenseite einen Füllkörper 7, der an seiner Oberseite eine Öffnung aufweist (nicht dargestellt), die von einem Flansch 8 eines nicht näher gezeigten Filterrahmens, der in den Füllkörper 7 eingeführt ist, ausgefüllt wird. Die bei geschlossener Tür der Trommel 4 zugewandte Fläche des Füllkörpers 7 ist perforiert und dient einerseits dem Luftdurchtritt zum Filterrahmen und andererseits der Abweisung der in der Trommel umherfallenden Wäsche vom Filterrahmen. Zum Türanschlag-Wechsel werden die Scharniere 6 rechts der Beschickungsöffnung 2 gelöst, die Tür um 180 gedreht und die Scharniere 6 an den Befestigungsstellen 17 wieder montiert.The tumble dryer shown in FIG. 1 has a control panel 1 on the front side in the upper region and a loading opening 2 arranged underneath, which is bordered by a door frame 3. The inside of the door frame forms a circular bearing plate (not shown) for the circular loading opening of the drum 4. To the right of the loading opening 2, the door 5 is pivotably mounted by means of two hinges 6. It carries a filler 7 on the inside, which has an opening on its upper side (not shown), which is filled by a flange 8 of a filter frame, not shown, which is inserted into the filler 7. The surface of the packing 7 facing the drum 4 when the door is closed is perforated and serves on the one hand to allow air to pass through to the filter frame and on the other hand to reject the laundry falling around in the drum from the filter frame. To change the door hinges, the hinges 6 on the right of the loading opening 2 are loosened, the door is rotated by 180 and the hinges 6 are mounted again at the fastening points 17.

Durch die in Fig. 2 und 3 sehr stark gezeichneten Linien ist jeweils eine Kontur des erfindungsgemäß gestalteten Türrahmens 3 gezeichnet. In Fig. 2 ähnelt diese Kontur sehr der Form eines Fernseh-Bildschirms mit Seiten 9 und 10, die als nach außen gekrümmte Sehnen eines gedachten Umkreises um ein Rechteck angesehen werden können. Die Seiten 9 und 10 stoßen an den Ecken 11 zusammen und sind hier miteinander durch eine stetige, aber im Vergleich zur Krümmung der Seitenlinien stärkeren Krümmung verbunden. Die obere Seite 9 deutet zugleich die Oberseite 8 des Füllkörpers 7 an, in deren Öffnung der nicht dargestellte Filterrahmen gesteckt wird. Der Schacht für den Filterrahmen kann maximal etwa so breit sein wie die mit breitem Strich gestrichelten Linien 12 andeuten. Demgegenüber zeigen die dünneren Linien die Kontur 13 einer bekannten kreisrunden Beschickungsöffnung, von deren Kreis oben entlang der Sehne 14 ein Segment abgeschnitten ist. Die gestrichelten Linien 15 deuten dabei an, wie breit ein Filterschacht in einem Füllkörper der bekannten Wäschetrockner sein kann. Aus dieser vergleichenden Darstellung ist eindeutig erkennbar, daß die Fläche, die vom Flusenfilter überdeckt werden kann, bei der erfindungsgemäßen Ausbildung der Beschickungsöffnung erheblich größer ist als beim Stand der Technik.A contour of the door frame 3 designed according to the invention is drawn in each case by the lines drawn very strongly in FIGS. 2 and 3. In Fig. 2, this contour is very similar to the shape of a television screen with pages 9 and 10, which can be viewed as outwardly curved chords of an imaginary radius around a rectangle. The sides 9 and 10 meet at the corners 11 and are here connected to one another by a constant curvature which is stronger than the curvature of the side lines. The upper side 9 also indicates the top 8 of the packing 7, in the opening of which the filter frame, not shown, is inserted. The shaft for the filter frame can at most be about as wide as the lines 12 indicated by a dashed line. In contrast, the thinner lines show the contour 13 of a known circular loading opening, from the circle of which a segment is cut off along the chord 14. The dashed lines 15 indicate how wide a filter shaft in a packing of the known tumble dryer can be. From this comparative illustration it can be clearly seen that the area which can be covered by the fluff filter is considerably larger in the configuration of the loading opening according to the invention than in the prior art.

Die in Fig. 3 dargestellte Variante für die Formung der Beschickungsöffnung 2 enthält ebenfalls nach außen gekrümmte Sehnen als seiten 9 und 10, die im gleichen Abstand zueinander angeordnet sind wie im Beispiel der Fig. 2. Lediglich die Ecken 16 sind in der Variante der Fig. 3 stärker ausgerundet, d.h. sie haben kleinere Krümmungen und verkürzen damit die Diagonalen der Beschickungsöffnung. In Anbetracht der Innenformung des Türrahmens als kreisrundes Lagerschild ist die in Fig. 3 dargestellte Variante vorteilhafter. Sie ermöglicht einen kleineren Durchmesser des Lagerschilds, was der Steifigkeit der Wäschetrommel durch einen breiteren Stirnbodenring und der Sicherheit und Standfestigkeit der vorderen Trommellagerung zugute kommt. Trotzdem bleibt die gute Zugänglichkeit und Einsehbarkeit in den Trommel-Innenraum erhalten, ohne gleichzeitig den Nachteil hinnehmen zu müssen, daß Wäscheteile unbeabsichtigt aus der Trommel fallen können, weil etwa die untere Kante der Beschickungsöffnung im Vergleich zum tiefliegenden Teil des Trommelmantels zu niedrig angeordnet wäre.The variant shown in FIG. 3 for the shaping of the loading opening 2 likewise contains outwardly curved tendons as sides 9 and 10, which are arranged at the same distance from one another as in the example in FIG. 2. Only the corners 16 are shown in the variant in FIG 3 more rounded, ie they have smaller curvatures and thus shorten the diagonal of the loading opening. In view of the internal shape of the door frame as a circular bearing plate, the variant shown in FIG. 3 is more advantageous. It enables a smaller diameter of the end shield, which benefits the rigidity of the laundry drum due to a wider front ring and the safety and stability of the front drum bearing. Nevertheless, the good accessibility and visibility into the interior of the drum is maintained without having to accept the disadvantage that laundry items can fall out of the drum unintentionally because the lower edge of the loading opening would be too low compared to the low-lying part of the drum shell.
