Abstract

The loading opening for the washing items is closed by a door with a basically frustrated conical (14) glass centre bowl (7) to prevent clothing being isolated on the flexible coupling between the mobile drum unit and the machine front panel. To also prevent such items being isolated on the conical door bowl various adaptations are devised, one of which, here described, has a partially helical land (18) extending from (12) near the rim (8) and the crown (9).

Description

Von vorn beschickbare Wäschebehandlungsmaschine Front-loadable laundry treatment machine
Die Erfindung betrifft eine von vorn beschickbare Wäschebehandlungsmaschine, vorzugsweise eine Waschmaschine, mit einem im Gerätegehäuse schwingend aufgehängten Laugenbehälter und mit einer im Laugenbehälter drehbaren Wäschetrommel, mit einer materialelastischen Manschette, über die der Laugenbehälter am Rand seiner frontseitigen Beschickungsöffnung flüssigkeitsdicht an die gehäuseseitige Beschickungsöffnung angeschlossen ist, sowie einer die gehäuseseitige Beschickungsöffnung verschließenden Tür mit einem zum Trommelinneren hin kegelstumpfartig ausgewölbten Füllkörper.The invention relates to a loadable from the front laundry treating machine, preferably a washing machine, with a swinging in the device housing lye container and with a washing tub rotatable in the tub, with a material-elastic sleeve through which the tub is liquid-tightly connected to the edge of its front loading port to the housing side feed opening, and a door closing the housing side opening with a frusto-conical bulging towards the interior of the drum.
Der Begriff „Kegelstumpf" soll nachfolgend als konischer Körper mit einer beliebigen Grundfläche mit stetigen Bögen beliebiger Radien verstanden werden, z. B. neben kreisförmigen Grundflächen auch mit ovalen, elliptischen oder eiförmigen Grundflächen. Nachfolgend ist die Erfindung anhand einer Waschmaschine beschrieben; sie kann jedoch auch bei einer Wäschetrockenmaschine Anwendung finden.The term "truncated cone" is to be understood below as a conical body with an arbitrary base surface with continuous arcs of arbitrary radii, eg, in addition to circular base surfaces also with oval, elliptical or egg-shaped base surfaces.The invention is described below with reference to a washing machine, but it can also find application in a laundry drying machine.
Um bei bekannten Waschmaschinen der eingangs genannten Art zu verhindern, dass beim Waschvorgang nach oben geförderte Wäschestücke auf dem topfförmigen Füllkörper liegen bleiben, wird im oberen Bereich des Füllkörpers eine nach innen gerichteten Abschrägung eingeformt. Die Wäsche kann an dieser Schräge abgleiten und fällt der Schwerkraft folgend zurück ins Trommelinnere. Diese einfache Form eines Wäscheabweisers ist bei vielen Waschmaschinen praktiziert.In order to prevent known washing machines of the type mentioned above, that during the washing process promoted up laundry items remain on the cup-shaped filling body, an inwardly directed chamfer is formed in the upper region of the packing. The laundry can slide off this slope and, following gravity, falls back into the interior of the drum. This simple form of a laundry deflector is practiced on many washing machines.
In einer besonders gestalteten Ausbildung eines abgeschrägten Füllkörpers weist in DE 102 28 602 A1 der nach innen gerichtete Bereich des Füllkörpers eine Struktur in Form von aneinander gereihten, flächenhaften Erhebungen und Vertiefungen auf. Mit dieser eingeformten welligen oder geriffelten Struktur des in den Wäschebehandlungsraum hinein ragenden Füllkörpers soll der Eintrag von Mechanik in das Waschgut verstärkt werden. Auf die Funktion als Wäscheabweiser wirkt sich die vorgeschlagene Formgebung nicht positiv aus, weil durch die Strukturierung der Oberfläche keine abweisende Kraftkomponente sondern eine in Kleinbereichen der Gewebeteile der Wäsche wirkende Walkarbeit geleistet wird.In a specially designed embodiment of a tapered filling body, in DE 102 28 602 A1, the inwardly directed region of the filling body has a structure in the form of planar, raised elevations and depressions. With this molded wavy or corrugated structure of the projecting into the laundry treatment space filling body of the entry of mechanics is to be reinforced in the laundry. On the function as a laundry deflector, the proposed shape does not have a positive effect, because the structure of the surface no repellent force component but acting in small areas of the fabric parts of the laundry flexing is done.
Bei laufender Waschmaschine, insbesondere beim Schleuderhochlauf, kommt es im allgemeinen zu unwuchtbedingten Schwingungen des elastisch aufgehängten Systems aus Laugenbehälter und Wäschetrommel. Außerdem schwingt in geringerem Umfang auch die flie- gend gelagerte Wäschetrommel gegenüber dem Laugenbehälter. Um zu vermeiden, dass die Trommel und die ortsfeste Manschette aneinander reiben, muss zwischen beiden ein ausreichender Abstand eingehalten werden. Gleiches gilt für den Abstand des Randes der Trommelöffnung in Bezug auf den ins Trommelinnere hineinragenden Füllkörper. Aus diesen Randbedingungen ergibt sich konstruktiv zwischen Trommelrand, Manschette und Füllkörper ein Ringspalt, der die Gefahr in sich birgt, dass beim Betrieb der Waschmaschine Wäscheteile in diesen Spalt gelangen und mit der rotierenden Trommel bewegte Wäscheteile an der ortsfesten Manschette reiben. Durch diese Reibung können sowohl die Wäsche als auch die Manschette beschädigt werden.When the washing machine is running, in particular during spin-up, it generally comes to unbalanced vibration of the elastically suspended system of tub and laundry drum. In addition, to a lesser extent, the floating Generally stored laundry drum opposite the tub. In order to avoid that the drum and the stationary sleeve rub against each other, a sufficient distance must be maintained between them. The same applies to the distance of the edge of the drum opening with respect to the inside of the drum projecting filler. From these boundary conditions constructively results between the edge of the drum, cuff and filling an annular gap, which carries the risk that, during operation of the washing machine get laundry parts in this gap and rub with the rotating drum moving laundry items on the stationary cuff. This friction can damage both the garment and the cuff.
Mit der Größe der Trommel und der Weite ihrer Einfüllöffnung verstärkt sich die Tendenz, dass Wäsche beim Waschen oder Schleudern vom hinteren Bereich der Wäschetrommel in den vorderen Bereich gefördert wird. Neben der Gefahr der Beschädigung der Wäsche und der Manschette durch gegenseitigen Abrieb bewirken die Reibungskräfte eine erhöhte Belastung des Trommelantriebsmotors. Bei vorgegebener Motordrehzahl steigt das notwendigerweise aufzubringende Antriebsmoment.With the size of the drum and the width of its filling opening, the tendency for laundry to be conveyed from the rear area of the laundry drum to the front area during washing or spinning increases. In addition to the risk of damage to the laundry and the cuff by mutual abrasion, the frictional forces cause increased stress on the drum drive motor. For a given engine speed increases the necessarily applied drive torque.
Die mit der drehenden Trommel bewegte Wäsche könnte auch in den Spalt zwischen dem Rand der Wäschetrommel und der Manschette eingeklemmt werden, was die Gefahr von Beschädigungen an der Wäsche im besonderen Maße erhöht und den Anlauf der Trommel beim Waschen und Schleudern erschwert oder sogar verhindern kann. Dies wird auch den Antriebsmotor übermäßig belasten. Derartige Gefahren sind insbesondere gegeben, wenn die Trommel bis zu ihrem maximalen Fassungsvermögen mit Wäsche befüllt ist.The moving with the rotating drum laundry could also be trapped in the gap between the edge of the laundry drum and the cuff, which increases the risk of damage to the laundry to a special degree and the start of the drum during washing and spinning difficult or even prevent. This will also overburden the drive motor. Such dangers are particularly present when the drum is filled to its maximum capacity with laundry.
Um den zuvor beschriebenen Gefährdungen begegnen zu können, sind Wäscheabweiser neben dem Füllkörper als Zusatzbauteile entwickelt worden. In DE 103 59 01 1 B3 wird vorgeschlagen, einen ringförmigen elastischen Wäscheabweiser am Laugenbehälter so anzubringen, dass der Raum zwischen dem Füllkörper und der Manschette zumindest teilweise ausgefüllt ist. Die so erzielte Einengung des Ringspaltes verringert die Gefahr, dass die Wäsche in diesen Raum eindringen kann.In order to be able to counteract the hazards described above, laundry deflectors have been developed in addition to the filler as additional components. In DE 103 59 01 1 B3 it is proposed to attach an annular elastic laundry deflector to the tub so that the space between the filler and the cuff is at least partially filled. The resulting narrowing of the annular gap reduces the risk that the laundry can penetrate into this room.
In DE 20 2004 012 221 U1 wird ein Wäscheabweiser beschrieben, der im oberen Bereich der Beschickungsöffnung am Laugenbehälter befestigt ist und in den von der Manschette umfassten Bereich hineinreicht. Der Wäscheabweiser hat eine Querschnittsfläche in Form eines Dreiecks mit symmetrischen oder asymmetrischen Flanken. Die Spitze des Dreiecks zeigt von oben zum Zentrum der Einfüllöffnung. Die Dreiecksform bewirkt ein Ablösen der Wäsche in beiden Drehrichtungen, bei symmetrischen Dreiecken in gleicher, bei asymmetrischen Dreiecken in drehrichtungsabhängiger Stärke. Das Waschgut wird dabei in eine senkrechte Richtung befördert. Zwecks Verringerung der Reibung am Wäscheabweiser ist dieser mit einer besonders gleitfähigen Beschichtung versehen.DE 20 2004 012 221 U1 describes a laundry deflector which is fastened to the tub in the upper region of the feed opening and extends into the area encompassed by the cuff. The laundry deflector has a cross-sectional area in the form of a triangle with symmetrical or asymmetrical flanks. The top of the triangle shows from the top to the center of the filling opening. The triangular shape causes a detachment of the laundry in both directions of rotation, in symmetrical triangles in the same, in asymmetric triangles in direction of rotation-dependent strength. The laundry is transported in a vertical direction. In order to reduce the friction on the laundry deflector this is provided with a particularly lubricious coating.
In der Praxis zeigt sich aber, dass durch den Einsatz der beschriebenen Wäscheabweiser Wäsche immer noch beschädigt wird und unerwünschte Reibung an der Manschette dennoch nicht zu verhindern ist.In practice, however, shows that the use of the described laundry deflector laundry is still damaged and unwanted friction on the cuff is still unavoidable.
Der Erfindung liegt die Aufgabe zugrunde, eine eingangs beschriebene Waschmaschine ohne den Einsatz zusätzlicher Einbauteile so zu gestalten, dass die Funktion der Wäscheabweisung erhalten bleibt, ja sogar noch verstärkt wird, ohne eine Beschädigung der Wäsche durch Reibung an der Manschette beim Betrieb der Waschmaschine zu riskieren, und dass der Betrieb der Waschmaschine im Hinblick auf den Antrieb der Wäschetrommel sicherer wird. Die Umsetzung der Erfindung und die mit ihrer Anwendung erzielbaren Vorteile sollen mit einem möglichst geringen Aufwand erreichbar sein.The invention has for its object to design a washing machine without the use of additional built-in components described above so that the function of the laundry rejection is maintained, and even enhanced without risking damage to the laundry by friction on the sleeve during operation of the washing machine , and that the operation of the washing machine with respect to the drive of the laundry drum safer. The implementation of the invention and the achievable with their application advantages should be achievable with the least possible effort.
Erfindungsgemäß wird die Aufgabe durch die im Anspruch 1 aufgeführten Merkmale gelöst. Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen angegeben, deren Merkmale einzeln oder in beliebiger Kombination miteinander oder mit den Merkmalen des Anspruches 1 angewendet werden können.According to the invention the object is achieved by the features listed in claim 1. Advantageous embodiments of the invention are specified in the subclaims, the features of which can be used individually or in any combination with one another or with the features of claim 1.
Die nach Maßgabe der vorliegenden Erfindung gestaltete Waschmaschine zeichnet sich dadurch aus, dass die Mantelfläche des Füllkörpers mindestens eine Einformung aufweist, die nahe dem größten Durchmesser des Kegelstumpfes beginnt und in Richtung auf den Trommelinnenraum und zum kleinsten Durchmesser des Kegelstumpfes hin an der Mantelfläche entlang eine ansteigende, einer Sichelform ähnelnde Fläche bildet. Die sichelförmige Fläche bildet eine Gleitfläche mit einer ins Trommelinnere gerichteten Steigung, die an ihr anliegende und in Drehbewegung befindliche Wäscheteile praktisch ohne Reibung an der Oberfläche des - zumeist aus Glas bestehenden - Füllkörpers ins Trommelinnere zurück weist.The designed according to the present invention washing machine is characterized in that the lateral surface of the packing has at least one indentation, which begins near the largest diameter of the truncated cone and in the direction of the drum interior and the smallest diameter of the truncated cone on the lateral surface along a rising forms a sickle-shaped surface. The crescent-shaped surface forms a sliding surface with a directed inside the drum pitch, which has virtually no friction on the surface of the - mostly consisting of glass - packing in the interior of the drum to her fitting and in rotation laundry parts.
Durch den erfindungsgemäßen Füllkörper wirkt nämlich beim Betrieb der Trommel auf die Wäsche eine Kraft, die ähnlich wie bei einer Förderschnecke eine Komponente tangential zur Mantelfläche des Füllkörpers hat und eine zusätzliche Kraftkomponente, die axial ins Trommelinnere gerichtet ist. Insbesondere diese axiale Kraftkomponente fördert die in den vorderen Trommelbereich gedrängte Wäsche zurück in den mittleren Bereich der Trommel und verhindert, dass Wäsche in den kritischen Bereich des Spaltes zwischen der Manschette und dem Füllkörper gelangt, ohne dass ein Kontakt mit der Manschette überhaupt erst zustande kommt.By the filler according to the invention namely acts on the laundry during operation of the drum, a force which has a component similar to a screw conveyor tangential to the lateral surface of the packing and an additional force component, the axially into the Drum interior is addressed. In particular, this axial force component conveys the laundry forced into the front drum region back into the middle region of the drum and prevents laundry from entering the critical region of the gap between the sleeve and the filling body, without first making contact with the sleeve.
Die Dynamik der erzeugten Kraft ist vor allem abhängig von der Drehzahl der Trommel, die Krafteinwirkung auf die Wäsche verstärkt sich beim Trommelhochlauf. Damit und insbesondere durch die axial wirkende Kraftkomponente unterscheidet sich die Wirkung des nach Maßgabe der Erfindung gestalteten Füllkörpers prinzipiell von der Funktionsweise bekannter Wäscheabweiser, abgesehen von der erheblich geringeren Reibung zwischen den Oberflächen des erfindungsgemäßen Wäscheabweisers und der Wäsche.The dynamics of the generated force is primarily dependent on the speed of the drum, the force on the laundry increases during drum run-up. Thus, and in particular by the axially acting force component, the effect of the filler designed according to the invention differs in principle from the operation of known laundry deflector, apart from the significantly lower friction between the surfaces of the laundry deflector according to the invention and the laundry.
Wie oben beschrieben, nimmt mit steigender Drehzahl der Trommel die Tendenz zu, dass die Wäsche bzw. Teile davon nach vorn aus der Trommelöffnung herausdrückt werden. Durch die erfindungsgemäße Ausformung des Füllkörpers ergibt sich der Vorteil, dass in gleichem Maße, d.h. ebenfalls mit steigender Drehzahl die Tendenz zunimmt, durch die trommeleinwärts wirkende Kraft die Wäsche wirkt wieder in die Trommel zurück zu befördern.As described above, as the rotational speed of the drum increases, the tendency of the laundry or portions thereof to be pushed forward out of the drum opening increases. The inventive shape of the packing results in the advantage that to the same extent, i. Also with increasing speed the tendency increases, by the drum-inward acting force, the laundry acts to bring back into the drum back.
Zur Erzeugung unterschiedlicher, auf die waschtechnologische Zielstellung ausgerichteter Abweiserwirkungen kann die der Sichelform ähnelnde Fläche unstetig dimensioniert und geformt sein. Abweichend von der bevorzugten Form mit einer konstanten Steigung kann die Sichelfläche entlang ihrer Erstreckung eine bereichsweise ungleichförmige Steigung aufweisen. Die Abweiserwirkung des Füllkörpers kann weiterhin dadurch beeinflusst werden, dass im Bereich der Einformung die Mantelfläche bereichsweise einen wechselnden Konuswinkel aufweist.In order to produce different deflection effects, which are oriented towards the wash-technological objective, the surface resembling the shape of a sickle can be dimensioned and shaped discontinuously. Notwithstanding the preferred form with a constant pitch, the sickle surface may have a partially non-uniform slope along its extent. The Abweiserwirkung of the packing can also be influenced by the fact that in the region of the indentation, the lateral surface area has a changing cone angle.
In Ausgestaltung der Erfindung weist der Füllkörper zwei gegenläufig ausgerichtete Einfor- mungen auf, wodurch in beiden Drehrichtungen der Trommel eine Abweiserwirkung erzielt wird. In Abhängigkeit davon, ob die Waschmaschine überwiegend gleichmäßig reversierend betrieben wird oder mit einer bevorzugten Drehrichtung, sind die entgegen gegenläufig ausgerichteten Einformungen symmetrisch oder asymmetrisch gestaltet. Die symmetrische Ausführungsform bewirkt, dass in beiden Drehrichtungen gleich große Abweiserkräfte auf das Waschgut übertragen werden. In der bevorzugten asymmetrischen Ausführungsform wird in Hauptdrehrichtung eine stärkere Abweiserwirkung erzeugt als in entgegen gesetzter Drehrichtung.In an embodiment of the invention, the filler has two oppositely oriented imprints, whereby a deflecting effect is achieved in both directions of rotation of the drum. Depending on whether the washing machine is operated predominantly uniformly reversing or with a preferred direction of rotation, the oppositely directed recesses are designed symmetrical or asymmetrical. The symmetrical embodiment has the effect that equally large deflecting forces are transmitted to the laundry in both directions of rotation. In the preferred asymmetric embodiment, in Main direction produces a stronger Abweiserwirkung than in the opposite direction of rotation.
Durch die erfindungsgemäß gestaltete Waschmaschine verringern sich die Reibung der Wäsche im Bereich der Einfüllöffnung sowie die Gefahr, dass Wäsche aus der Einfüllöffnung der Trommel herausbefördert wird. Der erfindungsgemäße Füllkörper bewirkt eine besonders schonende Rückweisung der Wäsche aus dem Bereich der Einfüllöffnung. Schäden am Waschgut durch Reibung werden signifikant verringert und die Lebensdauer der Manschette erhöht.The inventively designed washing machine reduces the friction of the laundry in the region of the filling opening and the risk that laundry out of the filling opening of the drum is conveyed out. The filler according to the invention causes a particularly gentle rejection of the laundry from the region of the filling opening. Friction damage to the laundry is significantly reduced and the service life of the cuff is increased.
Mit der verminderten Reibung wird auch die Belastung für den Trommelantriebsmotor reduziert. Sein Energieverbrauch sinkt, ein Verhindern des Trommelanlaufs durch eingeklemmte Wäscheteile wird wirkungsvoll verhindert. Im Vergleich zu Gerätekonfigurationen ohne Nutzung der Erfindung ist es möglich, Motoren geringerer Leistung einzusetzen, was eine Kostensenkung bedeuten kann. Ein weiterer Vorteil zeigt sich darin, dass mit der Anwendung der Erfindung eine für den Kunden signifikant wahrnehmbare Minderung der Geräuschentwicklung verbunden ist.With the reduced friction and the burden on the drum drive motor is reduced. Its energy consumption decreases, preventing drum startup due to trapped laundry parts is effectively prevented. Compared to device configurations without the use of the invention, it is possible to use motors of lower power, which can mean a cost reduction. A further advantage is that with the application of the invention, a significant reduction of the noise development is noticeable for the customer.
Der mit der Erfindung verbundene zusätzliche Aufwand beschränkt sich auf die einmalige Herstellung einer veränderten Spritzform für den besonders gestalteten Füllkörper. Der Fertigungsablauf bei der Herstellung des Füllkörpers sowie bei dessen Montage in den Rahmen der Beschickungstür bleiben unverändert. Weitere Anpassungen oder zusätzliche Einbauteile sind nicht erforderlich.The additional expense associated with the invention is limited to the one-time production of a modified injection mold for the specially designed packing. The manufacturing process in the production of the filler as well as its installation in the frame of the loading door remain unchanged. Further adjustments or additional built-in parts are not required.

In Fig. 1 ist eine Waschmaschine 1 gemäß dem Stande der Technik schematisch perspektivisch von vorn dargestellt. Im Gehäuse der Waschmaschine ist der Laugenbehälter 2 federelastisch aufgehängt, in dem die zur Aufnahme der Wäsche bestimmte Trommel 4 um eine waagerechte Achse drehbeweglich angeordnet ist. Laugenbehälter 2 und Trommel 4 weisen vorn je eine Öffnung 3 auf, die konzentrisch zueinander stehen und nahezu in derselben Ebene liegen - deshalb haben sie beide dasselbe Bezugszeichen - und über welche die Trommel 4 mit dem Waschgut be- und entladen werden kann.In Fig. 1, a washing machine 1 according to the prior art is shown schematically in perspective from the front. In the housing of the washing machine, the tub 2 is suspended resiliently in which the intended for receiving the laundry drum 4 is arranged rotatably about a horizontal axis. The tub 2 and the drum 4 each have an opening 3 at the front, which are concentric with each other and lie almost in the same plane - therefore they both have the same reference number - and on which the drum 4 can be loaded and unloaded with the laundry.
Die korrespondierend zur Beschickungsöffnung 3 des Laugenbehälters 2 / der Trommel 4 im Gerätegehäuse vorgesehene Öffnung ist über eine materialelastische Gummimanschette 5 mit der Öffnung 3 des Laugenbehälters 2 dichtend verbunden und mit einer schwenkbar schamierten Tür 6 verschließbar. Die Tür 6 trägt einen klarsichtigen Füllkörper 7 gemäß Stand der Technik. Bei geschlossener Tür 6 schließt der Füllkörper 7 über einen nicht dargestellten Dichtring der Manschette 5 den Arbeitsbereich der Waschmaschine flüssigkeitssicher nach außen ab. Der Füllkörper 6 ist über den abgewinkelten Randbereich 8 im Türrahmen fest eingespannt. Der als Kegelstumpf ausgebildete, nach innen konisch verjüngende Füllkörper 7 ragt bei geschlossener Tür 6 in die Öffnung 3 der Wäschetrommel 4. Damit soll verhindert werden, dass Wäschestücke aus dem Trommelinnenraum in den Bereich zwischen dem Füllkörper 7 und der Manschette 5 gelangen können, die aber wegen des erforderlichen Schwingraumes des Laugenbehälters 2 einen gehörigen Abstand zueinander haben. Ein senkrechter planer Bereich 9, über den der Betrieb in der Waschmaschine 1 verfolgt bzw. kontrolliert werden kann, schließt den Füllkörper 7 nach innen ab. Der Füllkörper 7 weist in bekannter Weise im oberen Drittel des Mantelbereiches des Kegelstumpfes eine Abschrägung 10 auf. Die Abschrägung 10 fungiert als Gleitfläche; durch die Trommeldrehbewegung nach oben beförderte Wäschestücke gleiten von der Abschrägung 10 des Füllkörpers 7 ab und fallen der Schwerkraft folgend zurück in die Trommel 4.The opening corresponding to the feed opening 3 of the tub 2 / the drum 4 provided in the device housing opening is sealingly connected via a material-elastic rubber sleeve 5 with the opening 3 of the tub 2 and closed with a hinged door 6 hinged. The door 6 carries a clear packing 7 according to the prior art. When the door 6 is closed, the filling body 7 closes the work area of the washing machine in a liquid-tight manner to the outside via a sealing ring, not shown, of the sleeve 5. The filler 6 is firmly clamped over the angled edge region 8 in the door frame. The trained as a truncated cone, inwardly tapered conical filler 7 protrudes with the door closed 6 in the opening 3 of the laundry drum 4. This is to prevent laundry from the drum interior in the area between the filler 7 and the sleeve 5 can pass, but because of the required vibration space of the tub 2 have a considerable distance from each other. A vertical plane region 9, via which the operation in the washing machine 1 can be tracked or controlled, closes the filling body 7 inwards. The filler 7 has in known manner in the upper third of the lateral region of the truncated cone a chamfer 10. The chamfer 10 acts as a sliding surface; Items of laundry conveyed upwards by the drum rotation slide off the chamfer 10 of the filling body 7 and fall back into the drum 4 in accordance with gravity.
Die Ausführungsbeispiele der erfindungsgemäß gestalteten Füllkörper 7 sind zur besseren Anschauung sowohl als Zeichnung und als auch als Bild mit schattierten Flächen wiedergegeben. Die erfindungsgemäß gestalteten Füllkörper treten an die Stelle des Füllkörpers 7 in Fig. 1. Anstelle der aus dem Stand der Technik bekannten Abschrägung 10 weisen die Füllkörper 7 der dargestellten Ausführungsbeispiele aber eine sichelförmige Einformung auf 1 1.The embodiments of the inventively designed filler 7 are shown for better intuition both as a drawing and as an image with shaded areas. Instead of the known from the prior art bevel 10, the packing 7 of the illustrated embodiments, but a sickle-shaped indentation to 1 first
Das erste Ausführungsbeispiel (Fig. 2 bis 6) weist entlang der Mantelfläche 14 des Füllkörper-Konus eine am Umfang sich erstreckende, vom tiefsten Ende 12 nahe dem größten Durchmesser des Kegelstumpfes stetig ansteigende Einformung 1 1 auf. Die Einformung 1 1 beginnt mit ihrem einen Ende 12 vor dem oberen Scheitelpunkt 16 des Füllkörpers 7, entgegen der Trommeldrehrichtung 13 um einen Winkel α versetzt, und erstreckt sich vom Scheitelpunkt 16 des Füllkörpers 7 in Trommeldrehrichtung 13 über einen Winkelbereich ß weiter, der deutlich größer als 90° ist. Die Einformung 1 1 , an beiden Enden 12 und 17 spitz auslaufend, bildet - vom Trommelinnenraum aus betrachtet - eine Fläche, die einer Sichelform 18 ähnelt. Die eingeformte Sichelfläche 18 weist ausgehend vom Ende 12 eine in den Trommelinnenraum gerichtete, konstante Steigung auf.The first exemplary embodiment (FIGS. 2 to 6) has, along the lateral surface 14 of the filler cone, an indentation 11 extending on the circumference and rising steadily from the deepest end 12 near the largest diameter of the truncated cone. The indentation 1 1 begins with its one end 12 in front of the upper vertex 16 of the packing 7, opposite to the drum rotation 13 offset by an angle α, and extends from the vertex 16 of the packing 7 in drum rotation direction 13 on an angle range ß on, the much larger than 90 °. The indentation 1 1, tapering at both ends 12 and 17, forms - viewed from the inside of the drum - a surface which is similar to a sickle shape 18. The molded-in sickle surface 18, starting from the end 12, has a constant pitch directed into the interior of the drum.
Die Einformung 1 1 ist so ausgeführt, dass Kanten vermieden werden und alle Übergänge fließend sind. In Abhängigkeit von der waschtechnologischen Zielstellung kann die Sichelfläche 18 unterschiedlich breit und umfänglich verschieden lang sein. Die Wirkung als Wäscheabweiser kann dadurch variiert und damit der waschtechnologischen Zielstellung ange- passt werden.The indentation 1 1 is designed so that edges are avoided and all transitions are fluid. Depending on the washing technology target position, the sickle surface 18 may be different in width and circumferentially different lengths. The effect as a laundry deflector can thus be varied and thus adapted to the washing technology technological objective.
Eine zusätzliche, in den Ausführungsbeispielen nicht dargestellte Möglichkeit die Abweiserwirkung zu variieren, besteht darin, die Sichelfläche 18 nicht als Planfläche sondern über ihre Länge und / oder ihre Breite konkav oder konvex bzw. zylindermantelförmig gekrümmt auszubilden. So geformt weist die Sichelfläche 18 eine zumindest bereichsweise unstetige Steigung auf. Eine weitere Gestaltungsmöglichkeit besteht darin, den Kegelstumpf des Füllkörpers 7 im Bereich der Einformung 1 1 so auszubilden, dass die Mantelfläche 14 im oberen Bereich eine andere Neigung zum Trommelinnenraum aufweist als im Seitenbereich ohne Einformung 1 1. Damit können das Abgleiten der Wäschestücke und die Kraft, mit der die Wäschestücke in die Trommel 4 zurück geführt werden, beeinflusst werden.An additional, not shown in the embodiments, the Abweiserwirkung to vary, is the sickle surface 18 is not curved as a flat surface but over its length and / or its width concave or convex or cylinder jacket-shaped curved. When shaped, the sickle surface 18 has an at least partially discontinuous pitch. Another design option is to form the truncated cone of the filling body 7 in the region of the indentation 11 in such a way that the lateral surface 14 has a different inclination to the interior of the drum in the upper area than in the lateral area without Indentation 1 1. This can be used to influence the slippage of the items of laundry and the force with which the items of laundry are fed back into the drum 4.
In Fig. 7 bis 10 ist ein zweites Ausführungsbeispiel eines Füllkörpers 7 dargestellt, das zwei gegenläufig ausgerichtete Einformungen 1 1 aufweist. Die beiden eingeformten Sichelflächen 18.1 und 18.2 sind unterschiedlich dimensioniert und ausgerichtet. Vom Scheitelpunkt 16 beginnend erstrecken sie sich ansteigend gegen die Drehrichtung 13 über einen Winkelbereich ßi bzw. mit der Drehrichtung 13 über einen Winkelbereich ß2. Abweichend zum ersten Beispiel laufen die Sichelflächen 18.1 und 18.2 nicht spitz aus. Die Abweiserwirkung der Einformungen 1 1 ist bei dieser Ausführungsform drehrichtungsabhängig, in der Hauptdrehrichtung 13 der Trommel 4 ist sie größer als in der entgegen gerichteten Drehrichtung. Ein solcher Füllkörper 7 ist besonders geeignet für Waschmaschinen 1 mit zwei Drehrichtungen beim Waschen, von denen die eine Drehrichtung gegenüber der anderen mit abweichender Hauptaufgabenstellung bedacht ist, z. B. zum Benetzen des Waschgutes.In Fig. 7 to 10, a second embodiment of a filling body 7 is shown, which has two oppositely directed recesses 1 1. The two molded sickle surfaces 18.1 and 18.2 are dimensioned and aligned differently. Beginning at the apex 16, they extend in increasing fashion against the direction of rotation 13 over an angular range βi or with the direction of rotation 13 over an angular range β 2 . Notwithstanding the first example, the sickle surfaces 18.1 and 18.2 are not pointed. The deflection effect of the recesses 1 1 is direction of rotation in this embodiment, in the main direction of rotation 13 of the drum 4, it is greater than in the opposite direction of rotation. Such a filling body 7 is particularly suitable for washing machines 1 with two directions of rotation during washing, of which one direction of rotation is considered with respect to the other with different main task, z. B. for wetting the laundry.
Für den Einsatz bei Waschmaschinen 1 , die im Wesentlichen gleichmäßig reversierend betrieben werden, kann der Einsatz eines Füllkörpers 7 vorgezogen werden, bei dem die Sichelflächen 18.1 und 18.2 gleich groß dimensioniert sind und zur senkrechten Mittelebene des Kegelstumpfes symmetrisch zu einander liegen. Die Wirkung als Wäscheabweiser ist bei einem solchen Füllkörper 7 in beiden Trommeldrehrichtungen 13 gleich stark.For use in washing machines 1, which are operated substantially uniformly reversing, the use of a filling body 7 can be preferred, in which the sickle surfaces 18.1 and 18.2 are of equal size and are perpendicular to the vertical median plane of the truncated cone to each other. The effect as a laundry deflector is equal in such a filler 7 in both drum rotation directions 13.
Bei den zuletzt aufgeführten Ausführungsvarianten ist die Funktion als Wäscheabweiser in beiden Drehrichtungen wirksam. Durch entsprechende Gestaltung der Steigungen und einer Asymmetrie der Einformungen 1 1 mit ihren Sichelflächen 18.1 und 18.2 kann die drehrich- tungsabhängige Abweiserwirkung in weiten Grenzen variiert und somit gezielt auf die Betriebsweise der Waschmaschine 1 zugeschnitten werden. In the last-mentioned embodiments, the function is effective as a laundry deflector in both directions of rotation. By appropriate design of the slopes and an asymmetry of the recesses 11 with their sickle surfaces 18.1 and 18.2, the rotational direction-dependent deflection effect can be varied within wide limits and thus tailored to the mode of operation of the washing machine 1.
