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 mit einer nahe einem gehäusefrontseitigen Fensterrahmen, dessen Öffnung eine einem Rechteck mindestens angenäherte Form aufweist schwenkbar gelagerten Tür verschließbar ist, die an ihrer Innenseite einen in die Öffnung des Fensterrahmens hineinragenden Füllkörper mit einer der Fensterrahmen-Öffnung angepaßten Form aufweist.The invention relates to a tumble dryer with a laundry drum which is rotatably mounted about an at least approximately horizontal axis and which has a circular loading opening in the front bottom, which can be closed with a door frame which is pivotably mounted near a front of the housing and whose opening has a shape which is at least approximated to a rectangle. which has on its inside a filler protruding into the opening of the window frame with a shape adapted to the window frame opening.

Ein derartiger Wäschetrockner ist aus US 4 677 760 bekannt. Darin ist aus Gründen der Ausgestaltung einer Aufnahmevorrichtung für zu trocknende Schuhe ein in die Öffnung des Fensterrahmens hineinragender Füllkörper vorgesehen, in dessen trommelseitige Aufnahmedurchbrüche Schuhbügel eingesetzt werden können. Bei Nichtgebrauch finden diese Schuhbügel im Hohlraum des Füllkörpers Platz. Die Öffnung des Fensterrahmens und der Füllkörper haben mindestens zwei scharfe Ecken, die zu Problemen bei der Abdichtung der Luftführung führen werden. Die Öffnung und der Füllkörper sind ferner sehr weit oben in bezug auf die Beschickungsöffnung der Wäschetrommel angeordnet und haben nur eine kleine Durchgriffsfläche, so daß der bekannte Wäschetrockner für die normale Handhabung zum Trocknen von Kleidungsstücken ungünstige Voraussetzungen hat.Such a tumble dryer is known from US 4,677,760. For reasons of the design of a receiving device for shoes to be dried, a filling body projecting into the opening of the window frame is provided, in the drum-side receiving openings of which shoe hangers can be inserted. When not in use, these shoe hangers find space in the cavity of the packing. The opening of the window frame and the Packings have at least two sharp corners, which will lead to problems when sealing the air duct. The opening and the filler are also very high up in relation to the loading opening of the laundry drum and have only a small access area, so that the known dryer has unfavorable conditions for normal handling for drying clothes.

Aus dem deutschen Gebrauchsmuster 81 30 602 ist ein weiterer Wäschetrockner bekannt. Der Fensterrahmen an der gehäuseseitigen Beschickungsöffnung ist kreisrund geformt und nimmt einen die Beschickungsöffnung ausfüllenden topfförmigen Füllkörper 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 Fensterrahmen-Öffnung an der Vorderwand des Trockner-Gehäuses wieder zu montieren. Dazu sind an der Montagestelle selbstverständlich entsprechende Befestigungsbohrungen vorzusehen.Another tumble dryer is known from German utility model 81 30 602. The window frame at the housing-side loading opening is circular in shape and receives a pot-shaped filling body which fills the loading opening and is symmetrically attached 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 pot through 180 ° and re-mount the hinge on the other side of the window frame opening on the front wall of the dryer housing. Appropriate mounting holes must of course be provided at the assembly point.

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

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 Fensterrahmen-Öffnung 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 Öffnung 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 abgeschlossenem 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 erstrekkenden Vortür ausgestattet sind, kann vor dem Öffnen der Tür kein Wäschekorb unter die Fensterrahmen-Öffnung gestellt werden, um herausfallende Wäschestücke etwa aufzufangen.To the side of the guides, larger space segments are lost for use by the filter, so that the total filter surface available requires a relatively high flow rate, which draws fluff through the screen to an increased extent, which could be stopped at a lower flow rate on the screen. Furthermore, the known shape of the enlarged window frame 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 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 that are equipped with a front door that covers the entire width of the housing and extends deep down to the floor, it is not possible to place a laundry basket under the window frame 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 Türanschlagwechsel durch Drehen der Tür um 180° möglich ist, damit der Montageaufwand beim Türanschlagwechsel gering bleiben kann, daß des weiteren die installierbare Siebfläche vergrößert und damit die Durchströmungsgeschwindigkeit verringert werden kann und daß schließlich die Unterkante der Fensterrahmen-Öffnung für eine komfortable Bedienung zwar niedrig genug aber kaum niedriger angeordnet ist als bei runden, nicht vergrößerten Fensterrahmen-Öffnungen.The invention has for its object to provide a tumble dryer of the type mentioned in such a way that on the one hand it is possible to change the door stop by rotating the door through 180 °, so that the assembly effort when changing the door stop can be kept to a minimum, that the screen area that can be installed is also increased and thus the flow rate decreased and that finally the lower edge of the window frame opening is arranged low enough for comfortable operation but hardly lower than with round, not enlarged window frame openings.

Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß die Wäschetrommel mit ihrer kreisrunden Beschickungsöffnung an einem innen am Fensterrahmen ausgebildeten kreisrunden Lagerschild gelagert ist und daß die Seitenlinien in der Form der Öffnung 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 Fensterrahmen-Öffnung 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 Fensterrahmen-Öffnung bildet auch gegenüber der Wäschetrommel eine nach außen gekrümmte Sehne, deren Bogenhöhe zur inneren Kontur des Trommelmantels noch genügend groß ist, um zu verhindern, daß in die Trommel geladene Wäschestücke ohne weiteres durch den geöffneten Fensterrahmen-Öffnung fallen. Die Form der Fensterrahmen-Öffnung, 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 Fensterrahmen-Öffnung eindringenden Füllkörper 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 laundry drum with its circular loading opening is mounted on a circular bearing plate formed on the inside of the window frame and that the side lines in the shape of the opening form outwardly curved chords of an imaginary circumference around the opening and the corners one to the Sidelines have a constant, but in comparison stronger curvature. The shape of the window frame 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 window frame opening also forms an outwardly curved chord with respect to the laundry drum, the bow height of the inner contour of the drum shell is still large enough to prevent laundry items loaded into the drum from falling easily through the opened window frame opening. The shape of the window frame 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 filler body penetrating into the window frame 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.

Der in Fig. 1 dargestellte Wäschetrockner hat an der Frontseite im oberen Bereich eine Bedienungsblende 1 und eine darunter angeordnete Fensterrahmen-Öffnung 2, die von einem Türrahmen 3 eingefaßt ist. Der Fensterrahmen bildet an der Innenseite ein kreisrundes Lagerschild (nicht dargestellt) für die kreisrunde Beschickungsöffnung der Trommel 4. Rechts der Fensterrahmen-Öffnung 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 Fensterrahmen-Öffnung 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 window frame opening 2 arranged underneath, which is bordered by a door frame 3. The inside of the window frame forms a circular bearing plate (not shown) for the circular loading opening of the drum 4. To the right of the window frame opening 2, the door 5 is pivotably mounted by means of two hinges 6. It carries on the inside a filler 7 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 Air passage to the filter frame and on the other hand the rejection of the laundry falling around in the drum from the filter frame. To change the door hinges, the hinges 6 on the right of the window frame opening 2 are loosened, the door is rotated by 180 ° and the hinges 6 are re-installed at the fastening points 17.

Durch die in Fig. 2 und 3 stark gezeichneten Linien ist jeweils eine Kontur des erfindungsgemäß gestalteten Fensterrahmens 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 sind an den Ecken 11 durch eine stetige, aber im Vergleich zur Krümmung der Seitenlinien stärkeren Krümmung miteinander 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 window frame 3 designed according to the invention is drawn by the lines drawn 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 are connected to one another at the corners 11 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 lint 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 Fensterrahmen-Öffnung 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 Fensterrahmen-Öffnung. In Anbetracht der Innenformung des Fensterrahmens 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 Fensterrahmen-Öffnung im Vergleich zum tiefliegenden Teil des Trommelmantels zu niedrig angeordnet wäre.The variant shown in Fig. 3 for the formation of the Window frame opening 2 also 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 more rounded in the variant in FIG. 3, ie they have smaller ones Curvatures and thus shorten the diagonals of the window frame opening. In view of the inner shape of the window 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 accidentally fall out of the drum, because the lower edge of the window frame opening is arranged too low compared to the low-lying part of the drum shell would.
