Description

Die Erfindung betrifft eine Waschmaschine mit einem im wesentlichen zylindrischen Laugenbehälter, welcher an einer Deckfläche eine Öffnung zum Einfüllen von Waschgut besitzt, wobei die Öffnung selbst oder eine korrespondierende Öffnung in einem den Laugenbehälter umgebenden Gehäuse durch eine schwenkbar am Laugenbehälter oder Gehäuse gelagerte Tür verschließbar ist, und mit einer Umfluteinrichtung, welche über eine Umflutleitung Waschflüssigkeit aus dem Laugenbehälter entnimmt und durch die Tür wieder in den Laugenbehälter einbringt.The invention relates to a washing machine with a substantially cylindrical tub, which has an opening for filling laundry, wherein the opening itself or a corresponding opening in a housing surrounding the tub by a pivotally mounted on the tub or housing door is closed, and with a Umfluteinrichtung which takes over a Umflutleitung washing liquid from the tub and introduces through the door back into the tub.

Eine Waschmaschine mit einer Umfluteinrichtung ist beispielsweise durch die DE 43 37 943 A1 bekannt. Dort ist, wie bei Haushaltwaschmaschinen üblich, zwischen einer Laugenbehälteröffnung und einer Gehäuseöffnung eine elastische Manschette angeordnet. Diese besitzt eine Öffnung, an die das Ende einer Umflutleitung herangeführt ist, so dass Waschflüssigkeit im Kreislauf aus dem Laugenbehälter entnommen und in dessen Öffnung wieder eingebracht werden kann.A washing machine with a Umfluteinrichtung is for example by the DE 43 37 943 A1 known. There is, as usual in household washing machines, arranged between a lye container opening and a housing opening an elastic sleeve. This has an opening to which the end of a Umflutleitung is introduced, so that washing liquid can be removed in the circulation from the tub and reintroduced into the opening.

Bei größeren gewerblich genutzten Waschautomaten werden sogenannte mitschwingende Türen eingesetzt, die die Laugenbehälteröffnung direkt verschließen, so dass die elastische Manschette entfällt. Dort ist es bekannt, die umgeflutete Waschflüssigkeit direkt über eine Öffnung in der Tür wieder in den Laugenbehälter einzubringen. Natürlich ist eine solche Einspülung über die Tür auch bei einer Haushaltwaschmaschine einsetzbar. Die bekannten Waschmaschinen verwenden Umflutleitungen, deren eines Ende aus dem Laugenbehälter geführt ist und deren anderes Ende an einen Stutzen in der Tür angekoppelt ist. Hierdurch ragt ein Teil der schlauchförmigen Umflutleitung in den Bereich vor dem Waschautomaten. Neben einem wenig ansprechenden Erscheinungsbild besteht der Nachteil, dass die Leitung beschädigt oder von vorbeigehenden Personen herausgerissen werden kann. Außerdem ist eine solche Leitungsverlegung optisch nachteilhaft.In larger commercial washing machines so-called mitschwingende doors are used, which close the lye container opening directly, so that the elastic sleeve is eliminated. There it is known to bring the flooded washing liquid directly through an opening in the door back into the tub. Of course, such a flushing the door can also be used in a household washing machine. The known washing machines use Umflutleitungen whose one end is guided out of the tub and the other end is coupled to a nozzle in the door. In this way, a part of the tubular Umflutleitung protrudes into the area in front of the washing machine. In addition to a less attractive appearance, there is the disadvantage that the line can be damaged or torn by passing people. In addition, such a cable routing is visually disadvantageous.

Der Erfindung stellt sich somit das Problem, bei einer Waschmaschine der eingangs genannten Art eine sichere Verlegung der Umflutleitung zu ermöglichen.The invention thus raises the problem of allowing a safe installation of Umflutleitung in a washing machine of the type mentioned.

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

Die mit der Erfindung erreichbaren Vorteile ergeben sich dadurch, dass die Umflutleitung mindestens aus einem ersten und einem zweiten Teil besteht und dass zwischen einem Ende des ersten Teils und einem Ende des zweiten Teils eine Kupplungsstelle angeordnet ist, die durch Schließen der Tür flüssigkeitsdicht verbindbar ist. Hierdurch besteht die Möglichkeit, den Teil der Leitung, der in die Tür mündet, unter Bauteilen der Tür zu verbergen oder wenigstens nah an der Tür entlang zu führen. Hierdurch wird die Gefahr einer Beschädigung dieses Teils erheblich gemindert.The advantages achievable with the invention result from the fact that the Umflutleitung consists of at least a first and a second part and that between one end the first part and an end of the second part, a coupling point is arranged, which is liquid-tight connectable by closing the door. This makes it possible to hide the part of the line that opens into the door, under components of the door or at least close to the door. This significantly reduces the risk of damage to this part.

Dabei ist es zweckmäßig, wenn das der Kupplungsstelle zugeordnete Ende des ersten Teils im Randbereich der Laugenbehälteröffnung oder Gehäuseöffnung angeordnet ist.It is expedient if the coupling point assigned to the end of the first part is arranged in the edge region of the tub opening or housing opening.

In einer vorteilhaften Ausführungsform ist der erste Teil der Umflutleitung wenigstens teilweise an oder unter einem am Laugenbehälter befestigten kreis- oder teilkreisförmigen Ballastgewicht angeordnet. Hierdurch ergibt sich eine einfache Montage, außerdem ist dann auch der erste Teil wenigstens bereichsweise nicht fliegend verlegt und deshalb bei der Montage geschützt.In an advantageous embodiment, the first part of the Umflutleitung is at least partially disposed on or under a fixed to the tub circular or partially circular ballast weight. This results in a simple installation, in addition, then the first part is at least partially laid not flying and therefore protected during assembly.

Es ist zweckmäßig, wenn das der Kupplungsstelle zugeordnete Ende des zweiten Teils im Randbereich der Tür angeordnet ist. Dabei ist es besonders vorteilhaft, wenn der zweite Teil der Umflutleitung wenigstens teilweise in einem Handgriff der Tür angeordnet ist. Dann sind keine zusätzlichen Blenden erforderlich. Ein nicht im Handgriff angeordneter Bereich des zweiten Teils der Umflutleitung kann dann entlang des Türrahmens verlegt sein.It is expedient if the coupling point assigned to the end of the second part is arranged in the edge region of the door. It is particularly advantageous if the second part of the Umflutleitung is at least partially disposed in a handle of the door. Then no additional panels are required. An area of the second part of the Umflutleitung not arranged in the handle can then be laid along the door frame.

Es ist vorteilhaft, wenn eine Verriegelungseinrichtung der Tür einen Motor umfasst, welcher die Tür in eine Verriegelungsposition zieht. Hierdurch wird die Kraft auf die Kupplung zwischen dem ersten und zweiten Teil der Umflutleitung erhöht und eine gute Dichtwirkung gewährleistet. Eine Selbstzentrierung ergibt sich, wenn die Kupplungsstelle aus einem kegelstumpfförmigen Endstück und einem entsprechenden Gegenstück besteht.It is advantageous if a locking device of the door comprises a motor which pulls the door into a locking position. As a result, the force is increased to the coupling between the first and second part of the Umflutleitung and ensures a good sealing effect. A self-centering arises when the coupling point consists of a frusto-conical end piece and a corresponding counterpart.

Figur 1 zeigt den Wasserlauf bei einer Waschmaschine 1 als Schemaskizze. Diese Waschmaschine besitzt einen Laugenbehälter 2, der einen zylindrischen Mantel 3, eine geschlossene Rückwand 4 und auf der Bedienseite eine ringförmige Kappe 5 umfasst. Die in der Kappe 5 angeordnete kreisförmige Einfüllöffnung 6 wird durch eine ebenfalls kreisförmige Tür 7 verschlossen. In dem Laugenbehälter 2 kann in bekannter Weise eine ebenfalls zylindrische Trommel 8 (siehe Figur 3) zur Aufnahme von Wäsche angeordnet sein. Der Laugenbehälter 2 wird bis zu einem vorgegebenen Niveau, in der Figur durch die Pfeilspitze 9 angedeutet, aufgefüllt. Hierzu führt eine erste Wasserleitung 10 von einem nicht dargestellten Wasseranschluss zu einem Waschmitteleinspülkasten 11. Das Waschmittel (nicht dargestellt) wird mitgenommen und zusammen mit dem Wasser, nun als Waschflüssigkeit, über die zweite Wasserleitung 12 dem Laugenbehälter 2 zugeführt. Die dritte Leitung 13 dient zur Entlüftung. Nach Beendigung des Waschprozesses kann die Waschflüssigkeit über einen am Laugenbehälter 2 angeordneten Abfluss 14 und eine daran angeschlossene Abflussleitung 15 mit vorgeschaltetem Abflussventil 17 entleert werden. Um die Befeuchtung der Wäsche zu verbessern, wird die Waschflüssigkeit während des Waschprozesses über eine Umfluteinrichtung im Kreislauf im unteren Bereich aus dem Laugenbehälter 2 heraus- und im oberen Bereich zurückgeführt. Hierzu ist im Abfluss 14 vor dem Abflussventil 17 eine Verzweigung angeordnet, an die sich eine Umflutleitung 19 anschließt. In der Umflutleitung 19 ist eine Umwälzpumpe 20 angeordnet. FIG. 1 shows the watercourse in a washing machine 1 as a schematic sketch. This washing machine has a tub 2, which comprises a cylindrical shell 3, a closed rear wall 4 and on the operating side an annular cap 5. The arranged in the cap 5 circular filling opening 6 is closed by a likewise circular door 7. In the tub 2 can also in a known manner cylindrical drum 8 (see FIG. 3 ) may be arranged to receive laundry. The tub 2 is filled up to a predetermined level, indicated by the arrowhead 9 in the figure. For this purpose, a first water line 10 from a water connection, not shown, leads to a Waschmitteleinspülkasten 11. The detergent (not shown) is taken along and fed together with the water, now as a washing liquid, via the second water line 12 to the tub 2. The third line 13 serves for venting. After completion of the washing process, the washing liquid can be emptied via an outlet 14 arranged on the tub 2 and a drain line 15 connected thereto with an upstream drain valve 17. In order to improve the moistening of the laundry, the scrubbing liquid is removed during the washing process via a circulating device in the lower region of the tub 2 and returned in the upper area. For this purpose, a branch is arranged in the drain 14 before the drain valve 17, to which a Umflutleitung 19 connects. In the Umflutleitung 19 a circulating pump 20 is arranged.

Erfindungsgemäß besteht die Umflutleitung mindestens aus einem ersten 21 und einem zweiten Teil 22, und zwischen einem Ende des ersten Teils 21 und einem Ende des zweiten Teils 22 ist eine Kupplungsstelle angeordnet, die durch Schließen der Tür 7 flüssigkeitsdicht verbindbar ist. Die weiteren Figuren 2 und 3 zeigen eine Ausführungsform einer solchen Umfluteinrichtung. In diesen Figuren 2 und 3 ist der Laugenbehälter 2 erkennbar. Figur 2 zeigt ihn bei geschlossener Tür 7 ohne, Figur 3 bei geöffneter Tür 7 mit einer Verkleidung 18.According to the invention the Umflutleitung consists of at least a first 21 and a second part 22, and between one end of the first part 21 and one end of the second part 22, a coupling point is arranged, which is liquid-tight connectable by closing the door 7. The others Figures 2 and 3 show an embodiment of such a flooding device. In these Figures 2 and 3 is the tub 2 recognizable. FIG. 2 shows him with the door closed 7 without, FIG. 3 with the door open 7 with a panel 18.

An der Kappe 5, von der hier nur die durch die Tür 7 verschlossene Einfüllöffnung 6 sichtbar ist, ist eine Platte 35 befestigt, welche Ballastgewichte 23 trägt. Unter dem Laugenbehälter 2 ist die Abflussleitung 15 mit vorgeschaltetem Abflussventil 17 und außerdem die Umwälzpumpe 20 sichtbar. Sie ist in den ersten Teil 21 der Umflutleitung integriert, so dass dieser erste Teil aus einer Saugleitung 24 vor der Umwälzpumpe 20 und einer Druckleitung 25 hinter der Umwälzpumpe 20 besteht. Ein Teil der Druckleitung 25 wird zwischen der Platte und den Ballastgewichten 23 geführt und endet in einem Austrittsbereich 27 in einer umlaufenden Abdeckung 36, welche den Rand der Einfüllöffnung 6 und die Verriegelungseinrichtung 34 einfasst (siehe Figur 3). Dieser Bereich 27 ist im Randbereich der Einfüllöffnung 6 angeordnet und wird durch den Rahmen 28 der Tür 7 verdeckt. Er stellt das Ende 21.1 des ersten Teils der Umflutleitung 21 dar und ist kegelstumpfförmig ausgebildet. Zu erkennen ist dieser Bereich 27 auch sehr gut in der Figur 3 bei geöffneter Tür 7. Der Handgriff 29 und der Türrahmen 28 sind in der Figur 2 durchsichtig dargestellt. Deshalb ist der zweite Teil 22 der Umflutleitung 19 sichtbar. Ein erstes Ende 22.1 liegt unter dem Rand der Tür. Es ist trichterförmig erweitert, siehe Figur 3. Auf diese Weise bilden das kegelstumpfförmige Ende 21.1 des ersten Teils und das trichterförmige Ende 22.1 des zweiten Teils 22 eine Kupplungsstelle, die bei geschlossener Tür die beiden Enden 21.1 und 22.1 verbindet. Von dem Ende 22.1 im Bereich der Kupplungsstelle erstreckt sich die Leitung 22 entlang des Türrahmens 28 durch einen Randausschnitt 30 unter den Handgriff 29. Unter dem Handgriff 29 verläuft sie bis zu dessen inneren Ende 29.1 und durchdringt in einer Öffnung 31 das Türschauglas 32. Die Öffnung 31 ist als Düse ausgeführt, so dass die Waschlauge gezielt auf die Wäsche gesprüht werden kann. Zum Verschließen der Tür 7 ist ein Haken 33 vorgesehen, der von einer am Laugenbehälter 2 angeordneten Verriegelungseinrichtung 34 gehalten wird. Die Verriegelungseinrichtung 34 umfasst einen Motor (nicht dargestellt), welcher den Haken und darüber die Tür in eine Verriegelungsposition zieht. Hierdurch wird einerseits die Einfüllöffnung 6 abgedichtet und andererseits die beiden Leitungsteile 21 und 22 der Umflutleitung 19 an der Kupplungsstelle flüssigkeitsdicht verbunden.On the cap 5, of which only the closed through the door 7 filling opening 6 is visible here, a plate 35 is fixed, which carries ballast weights 23. Under the tub 2, the drain line 15 with upstream drain valve 17 and also the circulating pump 20 is visible. It is integrated in the first part 21 of the Umflutleitung, so that this first part of a suction line 24 in front of the circulation pump 20 and a pressure line 25 behind the circulation pump 20 is. A portion of the pressure line 25 is guided between the plate and the ballast weights 23 and ends in an outlet region 27 in a peripheral cover 36, which surrounds the edge of the filling opening 6 and the locking device 34 (see FIG. 3 ). This region 27 is arranged in the edge region of the filling opening 6 and is covered by the frame 28 of the door 7. It represents the end 21.1 of the first part of the Umflutleitung 21 and is frusto-conical. To recognize this area 27 is also very good in the FIG. 3 with the door 7. The handle 29 and the door frame 28 are in the FIG. 2 shown transparent. Therefore, the second part 22 of the Umflutleitung 19 is visible. A first end 22.1 lies below the edge of the door. It is funnel-shaped, see FIG. 3 , In this way, the frustoconical end 21.1 of the first part and the funnel-shaped end 22.1 of the second part 22 form a coupling point, the two ends 21.1 and 22.1 when the door is closed combines. From the end 22.1 in the region of the coupling point, the line 22 extends along the door frame 28 by a peripheral cutout 30 under the handle 29. Under the handle 29 it extends to the inner end 29.1 and penetrates through an opening 31, the door sight glass 32. The opening 31 is designed as a nozzle, so that the wash liquor can be sprayed specifically on the laundry. To close the door 7, a hook 33 is provided, which is held by a arranged on the tub 2 locking device 34. The locking device 34 includes a motor (not shown) which pulls the hook and above the door into a locking position. As a result, on the one hand the filling opening 6 is sealed and on the other hand, the two line parts 21 and 22 of the Umflutleitung 19 connected liquid-tight at the coupling point.

Die Zeichnungen und die vorstehende Beschreibung offenbaren eine Ausführungsform, wie sie bei einer gewerblichen Waschmaschine mit einem mitschwingenden Laugenbehälter sinnvoll ist. Bei einer Haushaltwaschmaschine, bei welcher die Tür nicht am Laugenbehälter, sondern am Gehäuse scharniert ist, und bei dem dann Laugenbehälter und Gehäuse korrespondierende Öffnungen besitzen, muss dann auch das entsprechende Ende der ersten Umflutleitung, welches der Kupplungsstelle zugeordnet ist, am Gehäuse fixiert sein.The drawings and the above description disclose an embodiment useful in a commercial washing machine having a resonating tub. In a domestic washing machine, in which the door is not hinged to the tub, but on the housing, and in which then tub and housing corresponding openings have, then also the corresponding end of the first Umflutleitung, which is associated with the coupling point to be fixed to the housing.
