Erfindungsgemäß wird die Aufgabe mit den Merkmalen des Anspruchs 1 gelöst. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung ergeben sich aus den nachfolgenden abhängigen Ansprüchen.According to the invention the object is achieved with the features of
Hierzu wird nach der Erfindung vorgeschlagen, dass die Öffnung im Ballastgewicht endend als Einbuchtung ausgeführt ist. An dieser Stelle ist im verbleibenden Material des Ballastgewichts die Bohrung zur Aufnahme der Schraube angeordnet. Der Dom stellt mit seinem stirnseitigen Ende die Auflage für das Ballastgewicht in der Einbuchtung bereit, wobei der Hohlraum zwischen dem Dom und dem Ballastgewicht zumindest teilweise mit einer verformbaren Masse ausgefüllt ist. Der besondere Vorteil ist, dass durch die elastische Masse zwischen Zapfen und Innenrand der Einbuchtung ein Formschluss erzeugt wird, wodurch mögliche Relativbewegungen zwischen Ballastgewicht und Laugenbehälter vermieden werden. Für die Befestigung ist eine große Vorspannkraft nicht mehr notwendig, wodurch die Behälterwand im Auflagebereich nicht stark belastet wird. Dadurch wird die Lebensdauer erhöht und mögliche Risse aufgrund zu starker Spannungen oder Belastungen werden vermieden.For this purpose, it is proposed according to the invention that the opening is executed in the ballast weight ending as indentation. At this point, the bore for receiving the screw is arranged in the remaining material of the ballast weight. The dome provides with its front end the support for the ballast weight in the indentation, wherein the cavity between the dome and the ballast weight is at least partially filled with a deformable mass. The particular advantage is that a positive connection is generated by the elastic mass between the pin and the inner edge of the indentation, whereby possible relative movements between the ballast weight and the tub are avoided. For the attachment of a large biasing force is no longer necessary, whereby the container wall is not heavily loaded in the support area. As a result, the service life is increased and possible cracks due to excessive stresses or strains are avoided.
In einer vorteilhaften Ausgestaltung ist der Zapfen annähernd sternförmig ausgebildet. Hierzu umfasst der Zapfen radial nach innen gerichtete Einbuchtungen, in die sich die elastische Masse ausbreiten kann, wodurch eine Verzahnung zwischen der Masse und dem Zapfen bereitgestellt wird.In an advantageous embodiment, the pin is approximately star-shaped. For this purpose, the pin comprises radially inwardly directed recesses into which the elastic mass can spread, whereby a toothing between the mass and the pin is provided.

Hierbei kann die Befestigung unabhängig von den Gegebenheiten der Behälterwand ausgeführt werden. Insbesondere kann die Befestigungslasche mit einer höheren Materialstärke ausgeführt werden, um den Belastungen stand zu halten.In a further advantageous embodiment, at least one fastening tab is integrally formed on an end wall of the tub, on which the fastening pin extends from the plane of the end wall pioneering. Here, the attachment can be performed regardless of the circumstances of the container wall. In particular, the fastening tab can be made with a higher material thickness to withstand the stresses.
In einer zweckmäßigen Weiterbildung ist an der Befestigungslasche eine Mutter angeordnet, in welche die Schraube eingeschraubt ist. Damit wird eine feste Verschraubung erreicht, wobei im Kunststoffmaterial Gewindeeinformungen oder Verspannungen durch selbstschneidende Schrauben vermieden werden.In an expedient development, a nut is arranged on the fastening tab, in which the screw is screwed. Thus, a fixed screwing is achieved, wherein in Plastic material Avoid threading or tension caused by self-tapping screws.
In einer zweckmäßigen Ausführung besteht die verformbare Masse aus einem zähflüssigen bis weichen Material, welches aushärtbar ist und nach dem Aushärten eine Härte von 30 bis 80 ShoreA besitzt. Die Masse wird vor dem Anbringen des Ballastgewichts am freien Ende des Zapfens aufgebracht und durch das Anbringen des Ballastgewichts in die Hohlräume gequetscht. Nach dem Aushärten ist ein Formschluss zwischen Zapfen und dem Ballastgewicht im Bereich der Einbuchtung hergestellt, wobei die elastische Masse nach dem Aushärten eine verbleibende Härte von 30 bis 80 ShoreA besitzt und eine begrenzte Elastizität bereitstellt.In an expedient embodiment, the deformable mass consists of a viscous to soft material, which is curable and has a hardness of 30 to 80 ShoreA after curing. The mass is applied before attaching the ballast weight at the free end of the pin and squeezed by attaching the ballast weight in the cavities. After curing, a positive connection between the pin and the ballast weight in the region of the recess is produced, wherein the elastic mass after curing has a residual hardness of 30 to 80 ShoreA and provides a limited elasticity.
In einer weiteren Ausführung wird als verformbare Masse ein Kleber verwendet, wodurch die Festigkeit der Verbindung zwischen Zapfen und Ballastgewicht nochmals verbessert wird.In another embodiment, an adhesive is used as a deformable mass, whereby the strength of the connection between the pin and ballast weight is further improved.

In Fig. 1 ist eine Waschmaschine 8 mit einem Laugenbehälter 1 in einer Seitenansicht als Schnitt skizziert. Der Laugenbehälter 1 besteht zumindest aus einem zylindrischen Mantel 2, der eine Trommel 3 umgibt. Der zylindrische Mantel 2 wird durch zumindest eine Bodenwand 6a geschlossen. In der Bodenwand 6a ist eine Nabe 4 eingebunden, welche die Antriebswelle 5 für die mittels eines Motors 12 angetriebene Trommel 3 aufnimmt. Die vordere Stirnwand 6 ist mit einer Beladungsöffnung 7 versehen, die durch eine Tür 9 verschließbar ist. Am Mantel 2 und/oder an der Stirnwand 6 sind Ballastgewichte 10, 11 befestigt.In Fig. 1, a
In Fig. 2 ist der Laugenbehälter 1 in einer perspektivischen Ansicht von vorn dargestellt. Die Ballastgewichte 11 sind außenseitig an der vorderen Stirnwand 6 angeordnet, wobei sie als Teilkreisring ausgebildet sind und außenseitig in etwa dem Verlauf des Mantels 2 folgen und innenseitig die Beladungsöffnung 7 freihalten. Die Gewichte 11 sind mit Schrauben 13 an der Stirnwand 6 befestigt, wobei hierbei die Befestigung an Befestigungslaschen 14 erfolgt, die an der Stirnwand 6 und/oder am Mantel 2 angeformt sind.In Fig. 2, the
In Fig. 3 ist die Befestigung des Ballastgewichts 11 im Detail aufskizziert. An der Stirnwand 6 bzw. an der Lasche 14 ist ein Zapfen 15 angeformt, der sich aus der Ebene der Lasche 14 erhebt. Das Ballastgewicht 11 hat auf der Seite, die der Stirnwand zugewandt ist, eine Öffnung 16, die im Material des Ballastgewichts 11 endend ausgebildet ist. Das Ballastgewicht 11 hat im Bereich dieser Öffnung 16 eine Bohrung 23, die zur Durchführung der Schraube 13 dient. Der Zapfen 15 hat einen deutlich geringeren Querschnitt als die Öffnung 16, wodurch nach dem Auflegen des Ballastgewichts 11 auf die Stirnfläche 17 des Zapfens 15 ein umlaufender Hohlraum 18 verbleibt (Fig. 4). Dieser Hohlraum 18 wird mit einer elastischen bzw. verformbaren Masse 19 zumindest teilweise ausgefüllt. Hierbei ist die Masse 19 vor dem Anbringen des Ballastgewichts 11 im Bereich des Zapfens 15 aufgetragen worden.In Fig. 3, the attachment of the
In Fig. 4 ist das befestigte Ballastgewicht im Detail aufskizziert. Durch das Anziehen der Schraube 13, die in einer Mutter 20 auf der gegenüberliegenden Seite der Lasche 14 eingeschraubt wird, wird das Ballastgewicht 11 gegen die Stirnfläche 17 des Zapfens 15 gedrückt. Hierbei wird die Masse 19 verformt, so dass sie weitestgehend den umlaufenden Hohlraum 18 im Bereich der Öffnung 16 ausfüllt. Überschüssige Masse 19 kann sich in den Spalt zwischen Lasche 14 und Ballastgewicht 11 ausbreiten. Nach dem Aushärten besitzt die Masse eine Härte von 30 bis 80 ShoreA, so dass eine seitliche Bewegung des Ballastgewichts 11 gegenüber der Stirnwand 6 zumindest fast vollständig vermieden wird. Die Schraube 13 braucht das Ballastgewicht 11 nicht mehr so fest gegen die Stirnfläche 17 des Zapfens 15 zu drücken, so dass das Relaxionsverhalten im Kunststoff im Bereich der Befestigung bzw. der Auflage des Ballastgewichts 11 auf dem Zapfen 15 weitestgehend vermieden wird.In Fig. 4, the fastened ballast weight is sketched in detail. By tightening the
