Description

Die Erfindung betrifft eine Waschmaschine mit einem gegenüber dem Maschinengehäuse schwingbeweglichen Waschaggregat, umfassend neben einer Waschtrommel auch einen die Waschtrommel umgebenden Laugenbehälter, welches mittels einer aus wenigstens einer Stange gebildeten Transportsicherung gegen Stöße gesichert ist, und die Stange im gesicherten Zustand in Aufnahmeeinrichtungen an einem vorderen Gehäuseteil und in weiteren Aufnahmeeinrichtungen an der Rückwand des Maschinengehäuses fixiert ist, und wobei die Stange im Mittelbereich mit dem Aggregat über den Laugenbehälter mittels Laschen kraftschlüssig verbunden ist.The invention relates to a washing machine with a relative to the machine housing swingable washing unit, comprising in addition to a washing drum and the washing drum surrounding tub, which is secured by means of a transport protection formed from at least one bar against shocks, and the rod in the locked state in receiving devices on a front housing part and is fixed in other receiving devices on the rear wall of the machine housing, and wherein the rod in the central region with the unit via the tub by means of tabs is positively connected.

Beim Transport von Waschmaschinen kann es vorkommen, dass diese aus relativ großen Höhen auf die hinteren oder auf die vorderen Gehäusefüße fallen. Dies ist insbesondere bei der Versendung von mehreren Geräten durch Speditionen oder die Bahn möglich, da dort die Geräte aus Platzgründen übereinander gestellt werden und zum Entladen von nur einer Person aus ihrer erhöhten Position aus der oberen Ebene auf den Bodenbereich herunter gezogen werden. Damit bei diesen Transportarbeiten Beschädigungen im Inneren und hier insbesondere bei den schwingbeweglichen Waschaggregaten vermieden werden, bedient man sich so genannter Transportsicherungen, die insbesondere die schwingend gelagerten Teile in dem Waschmaschinengehäuse für den Transport verstarren. Die Transportsicherungen als solches werden durch zwei an der Rückwand vorgesehene Öffnungen in das Maschineninnere eingeführt, wobei die Stangen im gesicherten Zustand in Aufnahmeeinrichtungen an der Vorder- und der Rückseite des Maschinengehäuses fixiert sind. In der fixierten Stellung sind die Stangen im Mittelbereich mit dem Laugenbehälter über Laschen form- und/oder kraftschlüssig verbunden.When transporting washing machines, it may happen that they fall from relatively high heights on the rear or on the front housing feet. This is particularly possible when sending multiple devices by hauliers or the train, because there the devices are placed on top of each other for reasons of space and are pulled down for unloading only one person from its elevated position from the upper level to the bottom area. In order to avoid damage to the interior of this transport work and, in particular, to the oscillating washing units, so-called transport safeguards are used which, in particular, mask the vibrating parts in the washing machine housing for transport. As such, the transport locks are inserted into the interior of the machine through two openings provided on the rear wall, the bars, in the secured state, being fixed in receiving devices on the front and rear sides of the machine housing. In the fixed position, the rods in the central region with the tub are connected via tabs form and / or non-positively.

So ist beispielsweise aus der DE 199 14 370 C2 eine Transportsicherung bekannt, die insbesondere für Laugenbehälter aus Stahlblech bestimmt ist. Eine andere Transportsicherung ist aus der DE 102 50 494 C1 bekannt, bei der insbesondere die Aufnahmevorrichtungen für die Stangen und die Aufnahmelaschen mit zusätzlichen Dämpfungseinrichtungen versehen sind. Diese nach dem Stand der Technik bekannten Stangenlösungen sind für aus Kunststoff gefertigte Laugenbehälter ungeeignet, weil die Krafteinleitung über ausgestellte schmale Nasen und kleine Kontaktflächen den aus Kunststoff gefertigten Laugenbehälter derart beschädigen, dass Rissbildungen auftreten können mit der Folge, dass der Behälter nicht mehr die hinreichende Dichtigkeit aufweist.For example, from the DE 199 14 370 C2 a transport lock known, which is intended in particular for tub made of sheet steel. Another transport protection is from the DE 102 50 494 C1 in which in particular the receiving devices for the rods and the receiving lugs are provided with additional damping devices. These known from the prior art rod solutions are unsuitable for plastic tubs, because the introduction of force issued through narrow noses and small contact surfaces damage the plastic tub made such that cracking can occur with the result that the container is no longer sufficient tightness having.

Aus der DE 42 15 780 A1 ist eine Transportsicherung bekannt, bei welcher Schrauben durch die Rückwand gesteckt und in die Behälterwand eingeschraubt werden. Die Schrauben sind in ihrem Mittelbereich als gelochte Hülse aus gehärtetem Stahl ausgebildet, wodurch eine gewisse Federwirkung bereitgestellt wird. Auf diese Weise können Stöße bzw. Schwingungen des Laugenbehälters während des Transports in stark begrenztem Maße zugelassen werden.From the DE 42 15 780 A1 a transport safety device is known in which screws are inserted through the rear wall and screwed into the container wall. The screws are formed in their central region as a perforated sleeve made of hardened steel, whereby a certain spring action is provided. In this way, shocks or vibrations of the tub can be allowed during transport to a very limited extent.

Auch sind die bekannten Lösungen einer Verschraubung des Kunststofflaugenbehälters mit der Rückwand nicht möglich, weil diese Lösung eine sehr stabile Rückwand erforderlich macht, da die Hebelwirkung des Aggregates sehr hoch ist und die Abstützung nur einseitig erfolgen kann. Außerdem werden sehr lange Schrauben benötigt, da die Aggregate geneigt im Maschinengehäuse vorgehalten werden. Das Einbringen oder Entfernen einer solchen Transportsicherung kann nur mit Hilfe eines Werkzeugs erfolgen, was die Handhabung erschwert.Also, the known solutions screwing the plastic tub with the rear wall are not possible because this solution requires a very stable back wall, since the leverage of the unit is very high and the support can be done only on one side. In addition, very long screws are needed because the units are held inclined in the machine housing. The introduction or removal of such a transport lock can only be done with the help of a tool, which makes handling difficult.

Der Erfindung stellt sich somit das Problem, eine Waschmaschine mit einer Transportsicherung der eingangs genannten Art bereitzustellen, bei der eine Zerstörung oder Verformung der Behälterwand vermieden wird.The invention thus raises the problem of providing a washing machine with a transport lock of the type mentioned, in which destruction or deformation of the container wall is avoided.

Erfindungsgemäß wird dieses Problem mit den Merkmalen des Anspruchs 1 gelöst. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung ergeben sich aus den nachfolgenden Unteransprüchen.According to the invention this problem is solved with the features of claim 1. Advantageous embodiments and further developments of the invention will become apparent from the following subclaims.

Die mit der Erfindung erreichbaren Vorteile bestehen darin, dass eine optimale Ausnutzung der Materialeigenschaften bei minimalem Fertigungsaufwand erzielt wird. Die Transportstange wird nicht geschwächt und kann so optimal die Kräfte aufnehmen. Es ist auch keine Verstärkung mehr als Vollmaterial nötig. Falls erforderlich könnte hier auch sehr festes Material eingesetzt werden. Die Verriegelungsfunktion wird durch ein Kunststoffbauteil erreicht, da sich mit diesem Werkstoff am einfachsten komplizierte Funktionen erfüllen lassen.The advantages achievable with the invention are that optimum utilization of the material properties is achieved with minimal manufacturing effort. The transport bar is not weakened and can thus optimally absorb the forces. It is also no reinforcement more than solid material needed. If necessary, very solid material could also be used here. The locking function is achieved by a plastic component, as can be met with this material easiest complicated functions.

Hierzu ist zur Sicherung des Aggregats, insbesondere des Laugenbehälters, die Stange mit einem hülsen- oder rohrartigen Verriegelungselement versehen, welches einerseits den Form- oder Kraftschluss mit der Rückwand des Gehäuses, sowie andererseits den Form- oder Kraftschluss mit der/dem der Rückseite zugewandten angeformten Lasche oder Auge an dem Laugenbehälter herstellt. Diese Verriegelung ist besonders geeignet für einen Laugenbehälter aus Kunststoff mit einstückig angeformten Laschen, da mit dem Verriegelungselement die Krafteinwirkungen auf größere Flächen verteilt werden. Die Verstarrung des schwingbeweglichen Waschaggregates sowie die Verriegelung der Transportstange wird durch das Verriegelungselement als ein einfaches Kunststoffformteil, welches mit der Stange zusammenwirkt, in einfacher Weise herbeigeführt. Hierzu sind zur Verriegelung und zur Fixierung an dem rohrartigen Verriegelungselement Stege radial angeformt, die jeweils im Laschenbereich und im Rückwandbereich entsprechend der Stärke von Lasche und Rückwand eine Unterbrechung aufweisen. Das schwingbewegliche Waschaggregat wird somit auf Distanz zur Rückwand sowohl festgelegt als auch fixiert. Um insbesondere das Verriegelungselement und die Stange durch die Rückwand des Maschinengehäuses einzuführen, ist die Durchstecköffnung der Lasche in der Rückwand im wesentlichen kreisförmig ausgebildet, wobei diametral jeweils Aussparungen für das Durchdringen der Stege angeordnet sind.For this purpose, to secure the unit, in particular the tub, the rod is provided with a sleeve-like or tubular locking element, which on the one hand the positive or frictional connection with the rear wall of the housing, and on the other hand, the form or adhesion with the / the back facing formed Lug or eye produces on the tub. This lock is particularly suitable for a plastic tub with integrally molded tabs, since the force effects are distributed over larger areas with the locking element. The Verstarrung of the oscillating washing unit and the locking of the transport rod is brought about by the locking element as a simple plastic molding, which cooperates with the rod in a simple manner. For this purpose, webs are radially formed for locking and fixing to the tubular locking element, each in the tab area and in the Rear wall area according to the strength of tab and rear wall have an interruption. The oscillating washing unit is thus both fixed and fixed at a distance to the rear wall. In order to introduce in particular the locking element and the rod through the rear wall of the machine housing, the insertion opening of the tab in the rear wall is formed substantially circular, wherein diametrically respective recesses for the penetration of the webs are arranged.

In Weiterbildung der Erfindung ist das rohrartige Verriegelungselement aus einem Kunststoffformteil gebildet, welches endseitig auf die Stange gestülpt und durch einen Presssitz befestigt ist. Hierzu weist das hülsenartige Verriegelungselement am Innenumfang ein oder mehrere Klemmstege auf, die durch eine axial erstreckende Anlaufschräge die eingesetzte Stange fest umschließen und somit eine Befestigung durch Presssitz bereitstellen.In a further development of the invention, the tubular locking element is formed from a plastic molding, which is put on the end of the rod and fixed by a press fit. For this purpose, the sleeve-like locking element on the inner circumference on one or more clamping webs, which firmly enclose the inserted rod by an axially extending run-on slope and thus provide an attachment by press fit.

Zur Begrenzung des Einschubs in die Öffnung der Rückwand ist endseitig an dem Verriegelungselement ein tellerartiges Formteil angesetzt, welches nach dem Einschieben oder im verriegelten Zustand flächig an der Rückwand anliegt.To limit the insertion in the opening of the rear wall, a plate-like molded part is attached to the end of the locking element, which rests flat on the rear wall after insertion or in the locked state.

Die Verriegelung erfolgt nach dem Einsetzen der Transportstange mit dem Verriegelungselement in die vorgesehenen Öffnungen der Gehäuseteile und der Laschen des Laugenbehälters. Die Verriegelung wird durch Drehen des Verriegelungselements im eingesetzten Zustand erreicht. Hierbei werden die Stege aus ihrer Flucht zu den diametralen Aussparungen verdreht und liegen nach dem Verdrehen um ungefähr eine viertel Umdrehung mit ihren Stirnflächen gegen die die Durchstecköffnungen umgebenden Wandbereiche der Laschen bzw. Rückwand. Hierbei kann sich weder der Laugenbehälter in radialer oder axialer Richtung bewegen, noch kann die Transportstange herausgezogen werden.The locking takes place after insertion of the transport rod with the locking element in the openings provided for the housing parts and the tabs of the tub. The locking is achieved by turning the locking element in the inserted state. Here, the webs are rotated from their escape to the diametrical recesses and are after twisting by about a quarter turn with their end faces against the through-openings surrounding wall portions of the flaps or rear wall. Here, neither the tub can move in the radial or axial direction, nor can the transport bar be pulled out.

Um ein ungewolltes Lösen des Verriegelungselementes zu unterbinden, wird erfindungsgemäß vorgesehen, dass in dem tellerartigen Formteil eine federnde Rastnase, die beispielsweise ausgestanzt sein kann, zur Verdrehsicherung des Verriegelungselementes angeordnet ist. Diese Rastnase ist in einer zweckmäßigen Ausführungsform an einer flächig zum tellerartigen Formteil angeordneten Blattfeder befestigt, wobei die Blattfeder mit der Rastnase einstückig aus dem tellerartigen Formteil ausgeschnitten ist. Nach dem Verdrehen des Verriegelungselementes rastet die Rastnase hinter eine Kante der diametralen Aussparungen in der Öffnung der Rückwand ein.In order to prevent unwanted loosening of the locking element, the invention provides that in the plate-like molded part a resilient latching lug, which may be punched example, is arranged to prevent rotation of the locking element. This locking lug is fastened in an expedient embodiment on a flat surface arranged to the plate-like molded part leaf spring, wherein the leaf spring is cut with the latching lug in one piece from the plate-like molded part. After rotation of the locking element, the detent latches behind an edge of the diametrical recesses in the opening of the rear wall.

Für die Handhabung des Verriegelungselementes, um es beispielsweise zu lösen oder zu verspannen, sind an dem tellerartigen Formteil Griffelemente angeformt, die entsprechend wie die Streben radial ausgerichtet sind, und an der Rückwandseite des Maschinengehäuses zugänglich sind.For the handling of the locking element, for example, to solve it or to brace, handle elements are integrally formed on the plate-like molded part, which are aligned according to the struts radially, and are accessible on the rear wall side of the machine housing.

Wie insbesondere aus der Fig. 6 zu erkennen ist, ist die Durchstecköffnung 18 der Rückwand 11 im wesentlichen kreisförmig ausgebildet, wobei diametral jeweils Aussparungen 19 für das Durchdringen der Stege 15 angeordnet sind. Die Durchstecköffnung 17 der Lasche 12 ist in gleicher Weise ausgeführt.Fig. 4 shows in the perspective view of the fuse, in particular made of plastic tub 10, formed locking member 14 which is sleeve or tube-like slipped onto the rod 7 (Fig. 5). The locking element 14 combines two functions, on the one hand produces the positive and frictional connection with the rear wall 11 of the housing 2, and on the other hand the positive and frictional connection with the or the back facing integrally formed tab or eye 12 to the tub 6. In this case, webs 15 are radially formed for locking and fixing to the tubular locking element 14, which are interrupted in the tab area or in the rear wall area corresponding to the thickness of tab 12 and rear wall 11. As can be seen in particular from FIG. 6, the insertion opening 18 of the rear wall 11 is formed substantially circular, wherein diametrically respective recesses 19 for the penetration of the webs 15 are arranged. The insertion opening 17 of the tab 12 is executed in the same way.

Wie aus der Figur 4 zu erkennen ist, ist das rohrartige Verriegelungselement 14 aus einem einstückigen Kunststoffformteil gebildet, welches endseitig auf die Stange 7 gestülpt und kraftschlüssig in einen Presssitz geschoben ist. Es versteht sich nun von selbst, dass, wenn die Stange 7 in das rohrartige Verriegelungselement 14 eingeschoben wird, das Verriegelungselement 14 mittels der angeformten Vorsprüngen 23 eine Verdrehung der Stange 7 innerhalb des Verriegelungselements 14 verhindert. Wie in Fig. 5 dargestellt, sind im Innenumfang des rohrförmigen Verriegelungselementes 14 Klemmstege 25 angeformt, die sich gegen den Außenumfang der eingeschobenen Stange 7 drücken und somit einen guten Presssitz mit der Stange 7 bereitstellen. Denkbar ist hier auch, dass diese Befestigung durch Rastelemente oder durch einen Bajonettverschluss vorgenommen werden kann. Wie weiter aus Fig. 5 zu entnehmen ist, ragen die Vorsprünge 23 jeweils in Aussparungen 24, die an dem hinteren Ende der Stange 7 angeordnet sind. Hierdurch wird der Drehformschluss hergestellt, so dass die Stange 7 wenn das Verriegelungselement 14 verdreht wird, entsprechend mitgedreht wird. Wie aus der Figur 4 zu erkennen ist, ist endseitig an dem Verriegelungselement 14 ein tellerartiges Formteil 20 angesetzt, welches im verriegelten Zustand an der Rückwand 11 anliegt. Um ein ungewolltes Zurückdrehen des Verriegelungselementes 14 zu unterbinden, ist in dem tellerartigen Formteil 20 eine federnde Rastnase 21 mit Blattfeder 26 ausgestanzt, die in einer bestimmten Stellung, hier beispielsweise der 90°-Stellung, zur Verdrehsicherung des Verriegelungselementes 14 in eine der beiden diametralen Öffnungen 19 in der Rückwand 11 einrastet. Wie in Fig. 2 dargestellt, ist das Verriegelungselement 14 in der verriegelten Position dargestellt. In dieser Position ragt die Rastnase 21 durch die diametrale Öffnungserweiterung 19 in das Gehäuseinnere. Es versteht sich von selbst, dass, wenn die Transportsicherung wieder gelöst wird, die Rastnase 21 entsprechend zu entrasten ist, so dass die 90°-Stellung wieder zurück gedreht werden kann, um auf diese Weise das Verriegelungselement 14 aus der Rückwand 11 entfernen zu können. Um eine einfache Handhabung zu gewährleisten, sind an dem tellerartigen Formteil 20 Griffelemente 22 angeformt. In einer zweckmäßigen Ausführungsform sind sie entsprechend wie die Stege 15 radial ausgerichtet. Zur Handhabung des Verriegelungselementes 14, insbesondere zum Einsetzen, gilt es nun entsprechend die Stege 15 so auszurichten, dass sie durch die Durchtrittsöffnung 17 jeweils der Lasche 12 und der Durchtrittsöffnung 18 der Rückwand 11 hindurch geführt werden können, bis das tellerartige Formteil 20 an der Rückwand 11 des Maschinengehäuses 2 anliegt. Dann wird gemäß des auf dem tellerartigen Formteil 20 angedeuteten Pfeils die Verdrehung des Verriegelungselementes 14 über die Griffelemente 22 vollzogen, so dass die Stege 15 aus ihrer Durchsteckposition heraus gedreht und somit die Verriegelung vor und hinter der Durchstecköffnung 17 von Lasche 12 und der Durchstecköffnung 18 der Rückwand 11 vollzogen wird. Somit ist auf einfache Art und Weise mit einem Formteil die Fixierung des Laugenbehälters 6 vorgenommen und das Waschaggregat 3 zu Transportzwecken gesichert.As can be seen from Figure 4, the tubular locking member 14 is formed of a one-piece plastic molded part, which is slipped end to the rod 7 and frictionally pushed into a press fit. It goes without saying that when the rod 7 is inserted into the tubular locking element 14, the locking element 14 prevents rotation of the rod 7 within the locking element 14 by means of the integrally formed projections 23. As shown in Fig. 5, 14 clamping webs 25 are formed in the inner periphery of the tubular locking element, which press against the outer periphery of the inserted rod 7 and thus provide a good interference fit with the rod 7. It is also conceivable that this attachment can be made by locking elements or by a bayonet lock. As can further be seen from FIG. 5, the projections 23 each protrude into recesses 24, which are arranged at the rear end of the rod 7. As a result, the rotary mold closure is made, so that the rod 7 when the locking member 14 is rotated, is rotated accordingly. As can be seen from the figure 4, a plate-like molded part 20 is attached to the end of the locking element 14, which rests against the rear wall 11 in the locked state. In order to prevent unwanted turning back of the locking element 14, a resilient latching nose 21 is punched out with leaf spring 26 in the plate-like molded part 20, in a certain position, for example, the 90 ° position, to prevent rotation of the locking element 14 in one of the two diametrical openings 19 in the rear wall 11 locks. As shown in Fig. 2, the locking member 14 is shown in the locked position. In this position, the locking lug 21 protrudes through the diametrical opening extension 19 into the housing interior. It goes without saying that, when the transport lock is released again, the locking lug 21 must be unlocked accordingly, so that the 90 ° position can be rotated back to remove in this way the locking member 14 from the rear wall 11 can , In order to ensure easy handling, 20 handle elements 22 are formed on the plate-like molded part. In an expedient embodiment, they are aligned radially in accordance with how the webs 15. To handle the locking element 14, in particular for insertion, it is now appropriate to align the webs 15 so that they can be passed through the passage opening 17 of the tab 12 and the passage opening 18 of the rear wall 11 through until the plate-like molded part 20 on the rear wall 11 of the machine housing 2 is applied. Then, according to the direction indicated on the plate-like shaped part 20 arrow, the rotation of the locking element 14 via the gripping elements 22 completed so that the webs 15 is rotated out of its push-through position and thus the lock in front of and behind the insertion opening 17 of tab 12 and the insertion opening 18 of Rear wall 11 is completed. Thus, the fixing of the tub 6 is made in a simple manner with a molding and the washing unit 3 secured for transport purposes.
