Description

Die Erfindung bezieht sich auf eine Waschtrommel mit im Zuge des Trommelmantels gefalteten oder geprägten Mitnehmern, die aus einer Tiefstellung im Laugenbehälter und nach weiterer Drehung der Waschtrommel aus einer höheren Position durch in den Mitnehmer-Flanken oder -Firsten angeordneten Öffnungen auf die Wäsche gie­ßen, insbesondere auf eine mantelseitig beschickbare Waschtrommel deren Beschik­kungsöffnung durch wenigstens eine am Trommelmantel angelenkte Tür verschließbar ist.The invention relates to a washing drum with drivers folded or embossed in the course of the drum jacket, which pour onto the laundry from a lower position in the tub and after further rotation of the washing drum from a higher position through openings arranged in the driver flanks or ridges onto a washing drum that can be loaded on the casing side, the loading opening of which can be closed by at least one door hinged to the drum casing.

Aus der EP-A-245 721 ist eine ähnliche Waschtrommel bekannt, bei der sich aller­dings die Mitnehmer nicht im Zuge des Trommelmantels falten oder prägen lassen, weil der Mantel durchlaufend geformt ist und Schöpfvorrichtungen als geschnittene und geprägte Blechausformungen enthält. Dort werden die Mitnehmer als besondere, z.B. aus Kunststoff,geformte Teile von innen in die Trommel eingesetzt. Bei im Zu ge des Trommelmantels gefalteten oder geprägten Mitnehmern ist diese Ausführung nicht verwendbar.A similar washing drum is known from EP-A-245 721, in which, however, the drivers cannot be folded or embossed in the course of the drum casing because the casing is continuously shaped and contains scooping devices as cut and embossed sheet metal formations. There the drivers are shown as special, e.g. made of plastic, molded parts inserted from the inside into the drum. This version cannot be used for drivers that are folded or embossed in the drum casing.

Hier sind in den Mitnehmern Öffnungen eingeformt, derart, daß beim Durchgang des Mitnehmers durch die Flotte bei Drehung der Waschtrommel Flotte in die Mulde des Mitnehmers einströmt und bei weiterer Drehung der Trommel durch im Bereich des Mitnehmerscheitels eingebrachte Bohrungen ausfließt und so die Wäsche mit Flotte berieselt. Durch diese konstruktive Ausbildung kann Flotte eingespart und somit auch Aufwand an Wärmeenergie gemindert werden.Here, openings are formed in the drivers, such that when the driver passes through the liquor, when the washing drum rotates, the liquor flows into the trough of the driver and, when the drum rotates further, in the region of the Drivers' apex flows out holes and so sprinkles the laundry with liquor. This constructive training saves fleet and thus also reduces the amount of thermal energy.

Der Anmeldung liegt die Aufgabe zugrunde, bei einer eingangs genannten Waschtrom­mel den Stand der Technik weiterzubilden, insbesondere die Schöpfvorrichtung zu verbessern und zu vereinfachen, damit sie über einen langen Zeitraum in immer gleichbleibender Weise sicher und gleichmäßig funktioniert.The object of the application is to develop the state of the art in a washing drum mentioned at the outset, in particular to improve and simplify the scooping device so that it functions reliably and uniformly over a long period of time in a constant manner.

Die Erfindung löst diese Aufgabe dadurch, daß die Mitnehmer zur Außenseite der Trommel hin durch je eine Platte abgedeckt sind, die wenigstens annähernd in der Mantelfläche verläuft und eine, mindestens einen Schöpfschlitz aufweisende Schöpf­vorrichtung enthält. Durch diese Art der Ausbildung von Mitnehmern mit Schöpfvor­richtungen ist auch die Befähigung von Waschtrommeln zum Schöpfen und Abregnen von Lauge möglich, deren Mitnehmer im Zuge des Trommelmantels gefaltet oder geprägt sind. Diese Ausbildung ist zugleich einfach und billig und arbeitet über lan­ge Zeit gleichbleibend sicher und gleichmäßig.The invention solves this problem in that the drivers are covered towards the outside of the drum by a plate which runs at least approximately in the lateral surface and contains a scoop device having at least one scoop slot. This type of training of drivers with scooping devices also enables washing drums to be scooped and de-watered, the drivers of which are folded or embossed in the course of the drum jacket. This training is simple and cheap at the same time and works consistently safely and evenly over a long period of time.

In vorteilhafter Weise enthält die Schöpfvorrichtung wenigstens eine aus der Mantel­fläche herausragende Haube, die einen gegen Schöpfrichtung gewandten Schlitz hat. An der dem Schlitz gegenüberliegenden Seite der Schöpfvorrichtung ist ein in den Mitnehmer sich erstreckender Laugenabweiser angeordnet. Diese beiden Merkma­le dienen einerseits der Erhöhung der geschöpften Laugenmenge - die Haube bringt mehr Lauge in den Mitnehmer, der Laugenabweiser hält sie im Mitnehmer - und andererseits der Versteifung der Platte.Advantageously, the scooping device contains at least one hood protruding from the outer surface, which has a slot facing the scooping direction. On the side of the scooping device opposite the slot, a lye deflector extending into the driver is arranged. These two features serve on the one hand to increase the amount of lye used - the hood brings more lye into the carrier, the lye deflector holds it in the carrier - and on the other hand to stiffen the plate.

Die Platte weist mindestens eine sich in den Mitnehmer erstreckende Wand auf und ist durch einen die Wand durchbrechenden Zuganker in ihrer Montagelage gehalten. Hierdurch ist die Schöpfvorrichtung auf einfachste Weise im Mitnehmer befestigt.The plate has at least one wall that extends into the driver and is held in its mounting position by a tie rod that breaks through the wall. As a result, the scoop is fastened in the driver in the simplest way.

Die Wand kann sich vorteilhafterweise quer zur Längsausdehnung des Mitnehmers er­strecken und bildet dabei mindestens zwei Kammern. Durch mindestens zwei solcher Wände können noch mehr solcher Kammern gebildet werden, deren außen liegende von den Trommelböden begrenzt sind.The wall can advantageously extend transversely to the longitudinal extent of the driver and forms at least two chambers. At least two such walls can form even more such chambers, the outer ones of which are delimited by the drum bottoms.

Der Laugenabweiser kann in diesen Fällen als Stütze für zwei eine Kammer begren­zende Wände dienen. Hierdurch ist die Gefahr ihrer Beschädigung beim Auffädeln auf den Zuganker stark vermindert.In these cases, the suds deflector can serve as a support for two walls delimiting a chamber. As a result, the risk of their damage when threading onto the tie rod is greatly reduced.

Die Schöpfvorrichtung kann aus mehreren Kammern bestehen, wobei jeder Kammer ein Schlitz zugeordnet ist. Dadurch ist eine Einstellung der Schöpf- und Beregnungs­wirkung in Abhängigkeit von der Trommel-Drehrichtung leichter.The scoop can consist of several chambers, each chamber being assigned a slot. This makes it easier to adjust the scooping and sprinkling effect depending on the direction of drum rotation.

Hierzu kann auch eine Weiterbildung der Erfindung dienen, bei der die Schlitze be­nachbarter Kammern in unterschiedliche Schöpfrichtungen weisen.A development of the invention can also serve this purpose, in which the slots of adjacent chambers point in different scooping directions.

Gemäß einer anders fortgebildeten Ausführung der Erfindung erstreckt sich die Wand längs zur Längsausdehnung des Mitnehmers und teilt dadurch den Innenraum des Mitnehmers in zwei längliche Kammern auf. Hiermit läßt sich die Schöpfvorrichtung am sichersten und schonendsten im Mitnehmer befestigen. Die Schöpfschlitze können beidseitig an der Platte der Schöpfvorrichtung gelegen sein.According to another embodiment of the invention, the wall extends longitudinally to the longitudinal expansion of the driver and thereby divides the interior of the driver into two elongated chambers. This is the safest and most gentle way to attach the scoop in the driver. The scoop slots can be located on both sides of the plate of the scoop device.

Damit die durch die Türen oder Klappen an der Beschickungsöffnung hervorgerufene Unwucht ausgeglichen werden kann, ist vorgesehen, daß das Gegengewicht mit der Schöpfvorrichtung vereinigt ist.So that the unbalance caused by the doors or flaps at the loading opening can be compensated for, it is provided that the counterweight is combined with the scoop device.

Damit die Waschtrommel leichter drehbar ist, z.B. beim Einstellen der Waschtrom­mel mit der Beschickungsöffnung nach oben, ist nach einem weiteren Merkmal der Erfindung vorgesehen, daß in der Platte eine Handgriffmulde eingebracht ist.So that the washing drum can be rotated more easily, e.g. when adjusting the washing drum with the loading opening upwards, it is provided according to a further feature of the invention that a handle recess is introduced into the plate.

Die Platte kann auch Bestandteil eines Gehäuses sein, das von außen in den Mit­nehmer einsetzbar ist. Hierdurch läßt sich für die Schöpfvorrichtung ein Einsatzteil mit größtmöglicher Eigensteifigkeit bereiten.The plate can also be part of a housing that can be inserted into the driver from the outside. In this way, an insert part with the greatest possible inherent rigidity can be prepared for the scoop device.

In den Zeichnungen sind mehrere Ausführungsbeispiele von erfindungsgemäßen Schöpfvorrichtungen schematisch dargestellt. Es zeigen:

  • Fig 1 eine Schöpfvorrichtung mit gehäuseartiger Form als Einsatz für einen Mitnehmer,
  • Fig. 2 einen Schnitt durch die Schöpfvorrichtung entlang der Schnittlinie II-II in Fig. 1,
  • Fig. 3 einen senkrechten Schnitt durch eine horizontal gelagerte Wasch­trommel mit eingesetzten Schöpfvorrichtungen,
  • Fig. 4 eine Platte mit angesetzten Wänden als Schöpfvorrichtung,
  • Fig. 5 eine Schöpfvorrichtung gemäß Fig. 4, die in beiden Drehrichtungen der Waschtrommel wirksam ist,
  • Fig. 6 eine in mehrere Kammern aufgeteilte Schöpfvorrichtung gemäß Fig. 5 und
  • Fig. 7 eine ebenfalls in beiden Drehrichtungen der Waschtrommel wirksame Schöpfvorrichtung mit Gegengewicht und in Längsausdehnung geteilten Kammern.
Several exemplary embodiments of scooping devices according to the invention are shown schematically in the drawings. Show it:
  • 1 is a scoop with a housing-like shape as an insert for a driver,
  • 2 shows a section through the scooping device along the section line II-II in FIG. 1,
  • 3 shows a vertical section through a horizontally mounted washing drum with scoops inserted,
  • 4 a plate with attached walls as a scoop,
  • 5 is a scoop according to FIG. 4, which is effective in both directions of rotation of the washing drum,
  • 6 shows a scooping device divided into several chambers according to FIGS. 5 and
  • Fig. 7 is a scooping device also effective in both directions of rotation of the washing drum with counterweight and chambers divided in the longitudinal extent.

Die Schöpfvorrichtung 1 gemäß Fig. 1 und 2 besteht aus einem Gehäuse mit einer Platte 2 und einem Schöpfschlitz 3, Seiten- und Stirnwänden 4, 5 und Versteifungs- bzw. Haltewänden 6. Durch die Spitzen der dreieckigen Wände ist ein Zuganker 7 geführt, der die Trommelböden der Waschtrommel gegen den Zylindermantel 16 zieht. Dabei wird gleichzeitig die Schöpfvorrichtung in der Mitnehmermulde 8 gehal­ten. Dreht sich nun die Waschtrommel in Richtung des Pfeiles 9, so strömt beim Durchgang des Mitnehmers durch den unteren Teil des sie umgebenden Laugenbehäl­ters (nicht dargestellt) Lauge in Richtung des Pfeiles 10 in den Raum 11 der Schöpfvorrichtung ein. Nach Weiterdrehen der Waschtrommel entläßt der Raum 11 unter der Platte 2 die Lauge aus einer höheren Position des Mitnehmers durch die Öffnungen 12 in einer Flanke 13 des Mitnehmers oder in seinem First auf die Wä­sche herab. Ein Laugenabweiser 14 gibt einerseits der Schöpfvorrichtung 1 Halt in der Mitnehmermulde 8 und verhindert außerdem ein vorzeitiges Abströmen der Lauge aus dem Raum 11 zur Außenseite der Trommel. In der Platte 2 ist eine Vertiefung 15 eingebracht, die als Handgriffmulde zur Bewegung der Waschtrommel von Hand, dient. Dadurch kann die im Trommelmantel eingebrachte Beschickungsöffnung leicht von Hand nach oben gestellt werden. Der zur Befestigung der Schöpfvorrich­ tung in der Mitnehmermulde 8 dienende Zuganker 7 kann außerdem durch eine Fül­lung als Massenausgleich für die Beschickungsöffnung der Waschtrommel benutzt werden.1 and 2 consists of a housing with a plate 2 and a scoop slot 3, side and end walls 4, 5 and stiffening or retaining walls 6. A tie rod 7 is guided through the tips of the triangular walls the drum bottoms of the washing drum pulls against the cylinder jacket 16. At the same time, the scooping device is held in the driver trough 8. If the washing drum now rotates in the direction of arrow 9, liquor flows into the space 11 of the scooping device in the direction of arrow 10 when the driver passes through the lower part of the tub (not shown) surrounding it. After turning the washing drum further, the space 11 under the plate 2 releases the lye onto the laundry from a higher position of the driver through the openings 12 in a flank 13 of the driver or in its ridge. A lye deflector 14 on the one hand gives the scooping device 1 a hold in the driver trough 8 and also prevents the lye from flowing out prematurely from the space 11 to the outside of the drum. In the plate 2, a recess 15 is made, which serves as a hand recess for moving the washing drum by hand. As a result, the loading opening in the drum jacket can easily be raised by hand. The one for attaching the scoop device in the driving trough 8 serving tie rod 7 can also be used by a filling as a mass balance for the loading opening of the washing drum.

Figur 3 zeigt die Wirkungsweise der Schöpfvorrichtung. Die Waschtrommel 27 drehe sich hier beispielsweise in Pfeilrichtung 9, so daß beim Eintauchen der Schöpfvor­richtung 1 in die unten im Laugenbehälter 28 befindliche Lauge 17 durch den Schlitz 3 Lauge in den Raum 11 der Schöpfvorrichtung einfließt. Diese eingeflossene Lauge wird beim Weiterdrehen der Waschtrommel emporgehoben und aus einer höhe­ren Position durch die Öffnungen 12 im Mitnehmer auf die Wäsche geregnet. Die in Fig. 3 dargestellten Schöpfvorrichtungen sind nur in einer Drehrichtung der Wasch­trommel wirksam. Soll die Waschtrommel reversierend betrieben werden und in bei­den Drehrichtungen schöpfen, so sind die Schöpfvorrichtungen so in die Mitnehmer einzusetzen, daß einige Schöpfvorrichtungen in der einen Drehrichtung und die ande­ren Schöpfvorrichtungen in der anderen Drehrichtung wirksam sind.Figure 3 shows the operation of the scoop. The washing drum 27 rotates here, for example, in the direction of the arrow 9, so that when the scoop device 1 is immersed in the liquor 17 located in the bottom of the tub 28 through the slot 3, liquor flows into the space 11 of the scoop device. When the washing drum continues to rotate, this lye is lifted up and rained on the laundry from a higher position through the openings 12 in the driver. The scooping devices shown in Fig. 3 are only effective in one direction of rotation of the washing drum. If the washing drum is to be operated in a reversing manner and scooping in both directions of rotation, the scooping devices are to be inserted into the drivers in such a way that some scooping devices are effective in one direction of rotation and the other scooping devices in the other direction of rotation.

Die dargestellte Waschtrommel ist mantelseitig beschickbar und hat eine mit zwei Klappdeckeln 18 und 18′ durch den Verschluß 20 verschließbare Beschickungsöffnung 19. Zum Ausgleich dieser zusätzlichen Massen kann die dem Verschluß gegenüberlie­gende Schöpfvorrichtung 1 mit zusätzlichen Massen versehen sein.The washing drum shown can be loaded on the jacket side and has a loading opening 19 with two hinged lids 18 and 18 'which can be closed by the closure 20. To compensate for these additional masses, the scoop device 1 opposite the closure can be provided with additional masses.

Abweichend von Fig. 1 besteht die Schöpfvorrichtung gemäß Fig. 4 lediglich aus der Platte 2 und den Seitenwandteilen 4 - und hier nicht dargestellt - 5. Zur Verstei­fung der Schöpfvorrichtung können noch weitere Rippen 6 vorgesehen sein. Der Schlitz 3 wird hier durch eine die Platte 2 nach außen überragende Haube 21 gebil­det. Der auf der Gegenseite angeordnete Laugenabweiser 14 ermöglicht zusammen mit den Flankenflächen 22 der Seitenwandteile 4 und 5 bzw. der Rippen 6 einen gu­ten Sitz in der Mulde des Mitnehmers 8 und verhindert das ungewollte Abfließen der Lauge nach außen. Zugleich dient er ebenfalls der Versteifung der Platte 2 und der Wände 4 bis 6.1, the scooping device according to FIG. 4 only consists of the plate 2 and the side wall parts 4 - and not shown here - 5. Further ribs 6 can be provided to stiffen the scooping device. The slot 3 is formed here by a hood 21 projecting outwards from the plate 2. The lye deflector 14 arranged on the opposite side, together with the flank surfaces 22 of the side wall parts 4 and 5 or the ribs 6, allows a good fit in the trough of the driver 8 and prevents the lye from flowing out to the outside. At the same time, it also serves to stiffen the plate 2 and the walls 4 to 6.

Wie Figur 5 zeigt, kann die Schöpfvorrichtung auch so gebildet sein, daß sich meh­rere Kammern 23 ergeben, wobei die Haube 21 in der einen Drehrichtung der Trommel und die Haube 21′ in der anderen Drehrichtung der Trommel als Lauge schöpfende Schlitze 3 wirksam wird und den jeweiligen Kammerraum 23′ bzw. 23 je nach Drehrichtung der Waschtrommel mit Lauge füllen.As Figure 5 shows, the scooping device can also be formed so that there are several chambers 23, the hood 21 in one direction of rotation of the drum and the hood 21 'in the other direction of rotation of the drum as slots 3 scooping is effective and the Fill each chamber 23 'or 23 with lye, depending on the direction of rotation of the washing drum.

Wie Figur 6 zeigt, sind Seitenwandteile 4 und 5 gemäß Fig. 5 nicht unbedingt er­forderlich.Wenn die Schöpfvorrichtung in die Mulde eines Mitnehmers eingesetzt wird, der bereits seitliche Begrenzungswände durch die Trommelböden aufweist, sind die seitlichen Wände 4 und 5 entbehrlich. Zum sicheren Halten der Platte 2 am Zug­anker 7 genügen die Wände 6. Die Kammern 23 können in frei gewählter Anzahl und Aufteilung in der Schöpfvorrichtung enthalten sein. Dabei muß jede Kammer ei­nen Schlitz 3 aufweisen, der von der Haube 21 und der tiefer liegenden Kante des Trommelmantels zum Mitnehmer gebildet wird.As FIG. 6 shows, side wall parts 4 and 5 according to FIG. 5 are not absolutely necessary. If the scooping device is inserted into the trough of a driver that already has lateral boundary walls through the drum bottoms, the side walls 4 and 5 are unnecessary. The walls 6 are sufficient for securely holding the plate 2 on the tie rod 7. The chambers 23 can be contained in the scoop device in a freely selected number and division. Each chamber must have a slot 3, which is formed by the hood 21 and the lower edge of the drum shell to the driver.

Fig. 7 zeigt eine Schöpfvorrichtung mit Gegengewicht 24. Hier wird die Mulde des Mitnehmers durch eine Wand 25 in seiner Längsrichtung zweigeteilt. Die Platte 2 enthält ebenfalls - und zwar an beiden Seiten - Hauben 21 bzw. 21′, so daß die Schöpfvorrichtung in beiden Drehrichtungen der Waschtrommel wirksam ist. Die Platte 2 ist auch hier mit einer Handgriffmulde 15 versehen. Das Gegengewicht 24 kann aus demselben Material wie die Schöpfvorrichtung oder als besonderes Teil 26 aus einem spezifisch schwereren Material an der Schöpfvorrichtung befestigt sein. Vorzugsweise ist das Teil 26 vom (Kunststoff-)Werkstoff der Schöpfvorrichtung umgeben.7 shows a scoop device with counterweight 24. Here, the trough of the driver is divided in two by a wall 25 in its longitudinal direction. The plate 2 also contains - on both sides - hoods 21 and 21 ', so that the scoop is effective in both directions of rotation of the washing drum. The plate 2 is also provided with a handle recess 15 here. The counterweight 24 can be attached to the scoop from the same material as the scoop or as a special part 26 from a specifically heavier material. The part 26 is preferably surrounded by the (plastic) material of the scoop device.
