Description

Die Erfindung betrifft einen Laugenbehälter für eine Trommelwaschmaschine mit zumindest einem mittels Schraubverbindung befestigten Ballastgewicht, welches auf Auflagebereiche an der Behälterwand angedrückt wird, wobei für die Schraubverbindung an der Behälterwand jeweils ein Zapfen angeformt ist, der in eine korrespondierende Öffnung im Ballastgewicht ragt, wobei zwischen dem Zapfen und der Öffnung ein umlaufender Hohlraum verbleibt.The invention relates to a tub for a drum washing machine with at least one fastened by means of screw ballast weight, which is pressed onto bearing areas on the container wall, wherein for the screw on the container wall in each case a pin is formed, which projects into a corresponding opening in the ballast weight, wherein between the Spigot and the opening a circumferential cavity remains.

Ein derartiger Laugenbehälter ist aus der DE 42 38 686 C1 bekannt. Hierbei sind Ballastgewichte an den Stirnwänden angeschraubt, wobei an den Stirnwänden Dome angeformt sind, die in Öffnungen im Ballastgewicht ragen. Die Dome sind jeweils mit einer axialen Bohrung versehen, in die eine Schraube eingeschraubt wird, die mit ihrem Schraubenkopf das Ballastgewicht gegen den Auflagebereich drückt. Als Auflagebereich sind um die Zapfen umlaufende Rippen angeformt. Die Öffnung im Ballastgewicht wird mit einem Federteller überdeckt, der nach dem Einschrauben der Schraube eine Vorspannkraft auf das Ballastgewicht bereitstellt. Bei einem Laugenbehälter aus Kunststoff ist im Auflagebereich eine Relaxion nicht zu vermeiden, wodurch die Vorspannkraft allmählich nachlässt. Bei höheren Gewichten oder größeren Unwuchten kann sich das Ballastgewicht lockern und im schlimmsten Fall lösen.Such a tub is from the DE 42 38 686 C1 known. In this case, ballast weights are screwed to the end walls, wherein on the end walls dome are formed, which protrude into openings in the ballast weight. The domes are each provided with an axial bore into which a screw is screwed, which presses with its screw head the ballast weight against the support area. As a support area surrounding the pin circumferential ribs are formed. The opening in the ballast weight is covered with a spring plate, which provides a biasing force on the ballast weight after screwing the screw. In the case of a plastic tub, a relaxation can not be avoided in the contact area, whereby the preload force gradually decreases. At higher weights or larger imbalances, the ballast weight can loosen and in the worst case solve.

Auch WO 03/085187 A1 und DE 11 86 413 B offenbaren jeweils einen Laugenbehälter mit Ballastgewicht für eine Waschmaschine.Also WO 03/085187 A1 and DE 11 86 413 B each reveal a tub with ballast weight for a washing machine.

Aus der EP 0 798 412 A2 ist es bekannt, ein Ballastgewicht an einen Laugenbehälter mittels Spreizdübel zu befestigen. Hierbei hat das Ballastgewicht eine konische Durchgangsöffnung, die über einen Zapfen an der Laugenbehälterwand gestülpt wird. In den hohlen Zapfen wird wiederum ein kegel- oder keilförmiges Teil eingefügt, welches die Wandungen des Zapfens nach außen gegen den Innenumfang der Durchgangsöffnung des Ballastgewichts drückt. Durch das Auseinanderspreizen der Wandungen, die sich dann an die konische Durchgangsöffnung anschmiegen, wird das Ballastgewicht an der Behälterwand fixiert.From the EP 0 798 412 A2 It is known to attach a ballast weight to a tub by means of expansion dowel. Here, the ballast weight has a conical passage opening, which is slipped over a pin on the tub wall. In turn, a conical or wedge-shaped part is inserted in the hollow pin, which presses the walls of the pin outwardly against the inner circumference of the passage opening of the ballast weight. Due to the spreading apart of the walls, which then nestle against the conical passage opening, the ballast weight is fixed to the container wall.

Eine ähnliche Befestigung eines Ballastgewichts an einer Laugenbehälterwand ist aus der EP 0 799 926 A2 bekannt. Hierbei wird anstelle einer konischen Durchgangsöffnung ein zylindrisches Sackloch mit einer Längsöffnung im Ballastgewicht verwendet. Das dazugehörige, zylindrische Halteteil ist passgenau auf diese Öffnung dimensioniert, wobei mit einem Einsatzteil das Halteteil gespreizt und damit gegen die Wandungen der Öffnung gepresst wird.A similar attachment of a ballast weight to a suds tank wall is from the EP 0 799 926 A2 known. Here, a cylindrical blind hole is used with a longitudinal opening in the ballast weight instead of a conical passage opening. The associated, cylindrical holding part is dimensioned to fit this opening, wherein the holding part is spread with an insert and thus pressed against the walls of the opening.

Aus der DE 42 38 686 C1 ist es ferner bekannt, ein Ballastgewicht mittels einer Formmasse zu befestigen. Für diese Befestigungsart sind an der Behälterwand Stehbolzen angebracht, die in wesentlich größere Befestigungslöcher im Ballastgewicht ragen, wobei die Löcher mit der Formmasse ausgegossen sind. Diese Befestigung ist unlösbar und hat ferner den Nachteil, dass das Ballastgewicht vollständig von den Stehbolzen gehalten werden muss, wobei diese Verbindung bei hohen Gewichten oder starken Unwuchten hohen Kräften standhalten muss. Bei diesen Belastungsfällen sind Beschädigungen am Ballastgewicht selbst oder an der Behälterwand im Bereich des Stehbolzens möglich.From the DE 42 38 686 C1 It is also known to attach a ballast weight by means of a molding compound. For this type of attachment stud bolts are mounted on the container wall, which protrude into much larger mounting holes in the ballast weight, the holes with the Moldings are poured out. This attachment is insoluble and also has the disadvantage that the ballast must be completely held by the studs, and this connection must withstand high forces at high weights or heavy imbalances. In these load cases, damage to the ballast weight itself or to the container wall in the area of the stud bolt are possible.

Der Erfindung liegt somit die Aufgabe zugrunde, einen Kunststoff-Laugenbehälter mit einer verbesserten Befestigung des zumindest einen Ballastgewichts bereitzustellen.The invention is therefore based on the object to provide a plastic tub with an improved attachment of at least one ballast weight.

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 claim 1. Advantageous embodiments and modifications of the invention will become apparent from the following dependent claims.

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 Zapfen stellt mit seinem stirnseitigen Ende die Auflage für das Ballastgewicht in der Einbuchtung bereit, wobei der Hohlraum zwischen dem Zapfen 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 pin provides with its front end the support for the ballast weight in the indentation, wherein the cavity between the pin 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.

In einer weiteren vorteilhaften Ausführungsform ist an einer Stirnwand des Laugenbehälters zumindest eine Befestigungslasche angeformt, an dem sich der Befestigungszapfen von der Ebene der Stirnwand wegweisend erstreckt. 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 is a washing machine 8 with a tub 1 outlined in a side view as a section. The tub 1 consists at least of a cylindrical shell 2, which surrounds a drum 3. The cylindrical shell 2 is closed by at least one bottom wall 6a. In the bottom wall 6a, a hub 4 is integrated, which receives the drive shaft 5 for driven by a motor 12 drum 3. The front end wall 6 is provided with a loading opening 7 which can be closed by a door 9. On the jacket 2 and / or on the end wall 6 Ballastgewichte 10, 11 are attached.

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 tub 1 is shown in a perspective view from the front. The ballast weights 11 are arranged on the outside of the front end wall 6, wherein they are designed as a part circle and the outside approximately follow the course of the shell 2 and the inside keep the loading opening 7. The weights 11 are provided with screws 13 on the Attached end wall 6, in which case the attachment to fastening tabs 14 takes place, which are integrally formed on the end wall 6 and / or on the jacket 2.

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 ballast weight 11 is sketched in detail. On the end wall 6 and on the tab 14, a pin 15 is formed, which rises from the plane of the tab 14. The ballast weight 11 has on the side facing the end wall, an opening 16 which is formed in the material of the ballast weight 11 ending. The ballast weight 11 has in the region of this opening 16 a bore 23 which serves to pass the screw 13. The pin 15 has a significantly smaller cross-section than the opening 16, whereby after placing the ballast weight 11 on the end face 17 of the pin 15, a circumferential cavity 18 remains ( Fig. 4 ). This cavity 18 is at least partially filled with an elastic or deformable mass 19. Here, the mass 19 has been applied before attaching the ballast weight 11 in the region of the pin 15.

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 attached ballast weight is sketched in detail. By tightening the screw 13, which is screwed into a nut 20 on the opposite side of the tab 14, the ballast weight 11 is pressed against the end face 17 of the pin 15. Here, the mass 19 is deformed so that it fills largely the circumferential cavity 18 in the region of the opening 16. Excess mass 19 may spread into the gap between tab 14 and ballast weight 11. After curing, the mass has a hardness of 30 to 80 ShoreA, so that a lateral movement of the ballast weight 11 relative to the end wall 6 is at least almost completely avoided. The screw 13 does not need to press the ballast weight 11 so firmly against the end face 17 of the pin 15, so that the relaxation behavior in the plastic in the region of the attachment or the support of the ballast weight 11 on the pin 15 is largely avoided.

In Fig. 5 ist das befestigte Ballastgewicht 11 in einer anderen detaillierten, teilweise geschnittenen Ansicht mit aufskizziert. Die Schraube 13 drückt mit einer zwischen Schraube 13 und Ballastgewicht 11 eingelegten Scheibe 21 auf das Ballastgewicht 11. Die Unterseite des Ballastgewichts 11 liegt auf der Stirnfläche 17 des Zapfens 15 auf, wobei in einer vorteilhaften Ausführung der Zapfen 15 im Querschnitt sternförmig ausgebildet ist. Die Masse 19 wurde beim Anbringen des Ballastgewichts 11 an die Lasche 14 in den umlaufenden Hohlraum 18 und in die Aussparungen 22 gequetscht.In Fig. 5 the attached ballast weight 11 is sketched in another detailed, partially sectioned view. The underside of the ballast weight 11 is located on the end face 17 of the pin 15, wherein in an advantageous embodiment of the pin 15 is formed in cross-section star-shaped. The mass 19 was squeezed when attaching the ballast weight 11 to the tab 14 in the circumferential cavity 18 and in the recesses 22.
