- the inclined outer surfaces of the outer frets together form one Roof covered by a roof-shaped tension ring. When tensioning the The two roof surfaces of the outer frets are pulled towards one another by means of tension rings. This creates a stable connection between the tub and the Weight of the weight.
- the invention has for its object in a washing machine mentioned above to find a connection form for the weight of the weight on the tub, the external influences in all operating conditions of a washing machine remains unimpressed and easy to assemble. This should also be taken into account that a customer service case in the area of attachment of the weighting body does not enforce any special assembly requirements.
- this object is achieved in that a circle of spaced apart tabs is formed, which is perpendicular to the main plane of the Soil stand that within the circle at least three in one parallel to the main plane lying plane contact surfaces are formed on the floor and that the weight of the weight lying on the contact surfaces is held by the tabs is from the outside by a folded strap against the narrow surface of the weight of the weight are tense.
- connection form according to the invention is in terms of strength over the service life not critical. Different temperature strains have no influence on the Durability of the connection and tolerances of the weight of the weight are in the range of 1 mm across the diameter of the disc is not critical.
- the narrow lateral surface of the weight of the weight inclined is that the circular surface facing away from the plant side has a smaller diameter has as the plant-side circular area. This makes everyone's free end when cocking Forced tab on a smaller circular diameter, so that the weight of the weight in addition to the non-positive connection from the contact pressure of the strap is also positively attached to the bottom of the tub.
- the washing machine according to the invention can furthermore advantageously be designed as a result. that the tabs at their free end exceed the thickness of the strap Have survey. Especially in connection with the above training this gives the advantage that the strap is not over the free end the tabs can slide off them.
- tension band according to a further advantageous embodiment of the invention is finite steel strip and has parts for a turnbuckle at its ends, is the easiest way to obtain the necessary clamping pressure.
- the outer surface of the weight can then advantageously be placed under the turnbuckle just be flattened and at least one in the circle of the tabs Length of the turnbuckle corresponding gap may be provided.
- the flattening in this case, the lateral surface serves to form a preferred direction for the screw connection of the castle.
- the pulley is horizontally rotatably mounted in the tub 2 Laundry drum (not shown here) rotatably connected.
- the tub 2 is suspended via springs 7 in the housing 8 of the washing machine 1 and supported via shock absorbers 9 to the bottom 10 of the housing 8.
- a weight 12 attached, on the one hand as a counterweight to the mass of the drive device 3 and on the other hand as a damping mass for the vibrating tub system serves.
- the ring-shaped one is Structure of the weight 12 can be seen.
- the weight of the weight is in a flat pot-shaped structure of the base plate 11 inserted, the narrow shell-side Wall consists of tabs 13 which are spaced apart in a circle are arranged.
- the tabs 13 are an integral part of the plastic manufactured base plate 11.
- a gap 14 is left in the circle of the tabs on which a flattening 15 of the weight of the weight 12 is located. It serves as a level support for two each on End of a clamping band 16 attached clamps 17, which by a screw 18th to be pulled towards one another under tension on the ends of the tensioning strap 16.
- the detail IV shown in Fig. 4 enlarged in Fig. 2 shows the turnbuckle of Strap 16 in all details.
- Clamps 17 attached to the one hand to hold the screw head 21 of the Screw 18 and on the other hand to hold the nut 22 for the screw 18th serve.

- the strap 16 presses all the tabs 13 on the inclined Mantle surface 24 of the weight 12, thereby reducing the weight on the one hand non-positive due to the clamping pressure on the lateral surface and on the other hand form-fitting by reducing the angle between the contact surface 25 and the contact surfaces of the tabs 13 from 90 ° to 87.5 ° (corresponding to the inclination of 2.5 °).
- the profile of the tabs 13 is - as can be clearly seen in FIG. 6 - selected so that that the tabs in turn in their contact position with their outer surfaces form from 90 ° to the system side 25 of the weight 12. This is also a reduction in the risk of the tensioning strap 16 sliding off the Given tabs 13.
Abstract
Description
Die Erfindung betrifft eine Waschmaschine mit einem aus Kunststoff geformten Laugenbehälter für eine Wäschetrommel mit wenigstens annähernd horizontaler Drehachse und mit einem an einem Boden des Laugenbehälters angebrachten scheibenförmigen und wenigstens annähernd kreisförmigen Beschwerungsgewicht aus einem Werkstoff mit einer Dichte > 2 g/cm3.The invention relates to a washing machine with a plastic tub formed for a laundry drum with an at least approximately horizontal axis of rotation and with a disc-shaped and at least approximately circular weight attached to a bottom of the tub made of a material with a density> 2 g / cm 3 .
Eine solche Waschmaschine ist aus DE 42 38 686 C1 bekannt. Darin ist das Beschwerungsgewicht mit Durchbrüchen versehen, die mit am Boden des Laugenbehälters angebrachten, kegelstumpfförmigen Schraubtuben kongruieren. Von der Oberfläche des Beschwerungsgewichts her eingedrehte Schrauben ziehen einerseits Federteller weit in die Durchbrüche und andererseits die aus thermoplastischem Werkstoff bestehenden Schraubtuben von der Unterseite her ebenfalls in die Durchbrüche. Die Spannung soll dabei so groß sein, daß trotz der dem Thermoplast eigenen Relaxation am Ende der Lebensdauer noch genügend Spannkraft verbleibt. Abgesehen von den Schwierigkeiten genauer Anzugsmomente in einem derart diffizilen Bereich ist die erzielbare Homogenität eines Thermoplasten mit großer Wahrscheinlichkeit den Anforderungen an die Einhaltung der Bedingungen für diese Schraubverbindungen kaum gewachsen.Such a washing machine is known from DE 42 38 686 C1. This is the weight of the weight with openings that are attached to the bottom of the tub, Configure frusto-conical screw tubes. From the surface of the On the one hand, the weight of the screws turned in pulls the spring retainer far in the breakthroughs and on the other hand those made of thermoplastic material Screw tubes also from the bottom into the openings. The tension should be so large that, despite the relaxation inherent in the thermoplastic, at the end of the Life still has enough clamping force. Apart from the difficulties The achievable homogeneity is more precise tightening torques in such a difficult area of a thermoplastic with high probability the requirements on the Compliance with the conditions for these screw connections hardly grown.
Aus DE 32 17 160 A1 ist zwar eine in dieser Hinsicht unkritische Anbindungsform eines Beschwerungsgewichts bekannt, bei der in den Ring des Beton-Beschwerungsgewichts ein metallischer Außenreifen eingegossen ist, der einen schräg abgewinkelten Außenbund aufweist. In Höhe des Stirnbodens hat auch der Laugenbehälter einen solchen Außenbund. Dabei bilden die schrägen Außenflächen der Außenbünde gemeinsam ein Dach, das von einem dachförmigen Spannring übergriffen wird. Beim Spannen des Spannrings werden die beiden Dachflächen der Außenbünde aufeinander zu gezogen. Daraus entsteht eine stabile Verbindung zwischen dem Laugenbehälter und dem Beschwerungsgewicht.From DE 32 17 160 A1, an uncritical form of connection is one in this regard Weight weight known in the ring of the concrete weight a metallic outer tire is cast in, which has an obliquely angled outer collar having. The tub also has one at the front Outer waistband. The inclined outer surfaces of the outer frets together form one Roof covered by a roof-shaped tension ring. When tensioning the The two roof surfaces of the outer frets are pulled towards one another by means of tension rings. This creates a stable connection between the tub and the Weight of the weight.
Der Nachteil dieser Anbindungsform besteht einerseits in der ungünstigen Materialpaarung zwischen Beton und Stahl im Bereich des eingegossenen Außenreifens. Da sich der Außenreifen bei Temperaturerhöhung stärker ausdehnt als der Betonkörper, wird die innige Verbindung zwischen diesen beiden Teilen allmählich aufgegeben. Darunter wird die Festigkeit der Verbindung leiden. An die Maßhaltigkeit des Beschwerungsgewichts werden hohe Anforderungen gestellt, damit das Beschwerungsgewicht am Stirnboden satt anliegt, wenn der Spannring mit seinem Firstbereich etwa bereits auf den Außenkanten der Außenbünde aufliegt. Außerdem ist die Montierbarkeit des bekannten Beschwerungsgewichts dadurch beeinträchtigt, daß es so lange in Höhe des Stirnbodens gehalten werden muß, bis der Spannring angelegt ist.The disadvantage of this type of connection is, on the one hand, the unfavorable material pairing between concrete and steel in the area of the cast-in outer tire. That I the outer tire expands more than the concrete body when the temperature rises the intimate connection between these two parts gradually gave up. Underneath the strength of the connection will suffer. The dimensional accuracy of the weight high demands are made so that the weight of the weight on The front end fits snugly when the clamping ring with its ridge area is already open the outer edges of the outer frets. In addition, the mountability of the known Weight affected by the fact that it has been in the amount of End face must be held until the clamping ring is applied.
Der Erfindung liegt die Aufgabe zugrunde, bei einer eingangs genannten Waschmaschine eine Anbindungsform für das Beschwerungsgewicht am Laugenbehälter zu finden, die bei allen Betriebsbedingungen einer Waschmaschine von äußeren Einflüssen unbeeindruckt bleibt und einfach zu montieren ist. Dabei soll auch darauf Rücksicht genommen werden, daß ein Kundendiensteinsatzfall im Bereich der Befestigung des Beschwerungskörpers keine besonderen Montageanforderungen erzwingt.The invention has for its object in a washing machine mentioned above to find a connection form for the weight of the weight on the tub, the external influences in all operating conditions of a washing machine remains unimpressed and easy to assemble. This should also be taken into account that a customer service case in the area of attachment of the weighting body does not enforce any special assembly requirements.
Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß an den Boden ein Kreis von zueinander beabstandeten Laschen angeformt ist, die senkrecht zur Hauptebene des Bodens stehen, daß innerhalb des Kreises mindestens drei in einer parallel zur Hauptebene gelegenen Ebene liegende Anlageflächen an den Boden angeformt sind und daß das Beschwerungsgewicht auf den Anlageflächen liegend von den Laschen gehalten ist, die von außen durch ein umgelegtes Spannband gegen die schmale Mantelfläche des Beschwerungsgewichts gespannt sind.According to the invention this object is achieved in that a circle of spaced apart tabs is formed, which is perpendicular to the main plane of the Soil stand that within the circle at least three in one parallel to the main plane lying plane contact surfaces are formed on the floor and that the weight of the weight lying on the contact surfaces is held by the tabs is from the outside by a folded strap against the narrow surface of the weight of the weight are tense.
Die erfindungsgemäße Anbindungsform ist hinsichtlich der Festigkeit über die Lebensdauer unkritisch. Unterschiedliche Temperaturdehnungen haben keinen Einfluß auf die Haltbarkeit der Verbindung und Toleranzen des Beschwerungsgewichts sind im Bereich von 1 mm über den Durchmesser der Scheibe unkritisch. Außerdem läßt sich ein erfindungsgemäßes Beschwerungsgewicht leicht montieren, weil die Laschen das Beschwerungsgewicht bereits halten, ehe das Spannband aufgezogen ist, und weil sich das Beschwerungsgewicht beim Spannen des Spannbandes automatisch im Kreis der Laschen zentriert. Da das Beschwerungsgewicht zur Befestigung am Laugenbehälter an keiner Stelle punktförmig belastet wird, entfällt außerdem die Gefahr von Spannungsrissen im Gewicht. Sofern bereits Risse im Gewicht vorhanden sind, werden diese durch die Verspannung über den Umfang zusammengepreßt.The connection form according to the invention is in terms of strength over the service life not critical. Different temperature strains have no influence on the Durability of the connection and tolerances of the weight of the weight are in the range of 1 mm across the diameter of the disc is not critical. In addition, one can Mount the weight of the weight according to the invention easily, because the tabs the weight of the weight already hold before the strap is pulled up, and because the weight of the weight automatically when tightening the strap in the circle of Centered tabs. Since the weight of the weight for attachment to the tub there is no risk of stress cracks at any point in weight. If there are already cracks in the weight these are compressed by the tension over the circumference.
In besonders vorteilhafter Weise wird die erfindungsgemäße Waschmaschine dadurch weitergebildet, daß die schmale Mantelfläche des Beschwerungsgewichts derart geneigt ist, daß die der Anlageseite abgewandte Kreisfläche einen kleineren Durchmesser hat als die anlageseitige Kreisfläche. Dadurch wird beim Spannen das freie Ende jeder Lasche auf einen kleineren Kreisdurchmesser gezwungen, so daß das Beschwerungsgewicht neben der kraftschlüssigen Verbindung aus dem Anpreßdruck des Spannbandes auch noch formschlüssig am Boden des Laugenbehälters befestigt ist.This makes the washing machine according to the invention particularly advantageous further developed that the narrow lateral surface of the weight of the weight inclined is that the circular surface facing away from the plant side has a smaller diameter has as the plant-side circular area. This makes everyone's free end when cocking Forced tab on a smaller circular diameter, so that the weight of the weight in addition to the non-positive connection from the contact pressure of the strap is also positively attached to the bottom of the tub.
Die erfindungsgemäße Waschmaschine ist weiterhin vorteilhaft dadurch auszubilden. daß die Laschen an ihrem freien Ende eine die Dicke des Spannbandes überragende Erhebung aufweisen. Insbesondere im Zusammenhang mit der vorstehenden Weiterbildung ergibt sich daraus der Vorteil, daß das Spannband nicht über das freie Ende der Laschen von diesen abrutschen kann.The washing machine according to the invention can furthermore advantageously be designed as a result. that the tabs at their free end exceed the thickness of the strap Have survey. Especially in connection with the above training this gives the advantage that the strap is not over the free end the tabs can slide off them.
Wenn das Spannband gemäß einer weiteren vorteilhaften Ausbildung der Erfndung ein endliches Stahlband ist und an seinen Enden jeweils Teile für ein Spannschloß aufweist, ist die Herstellung des nötigen Spanndruckes auf einfachste Weise zu erwirken.If the tension band according to a further advantageous embodiment of the invention is finite steel strip and has parts for a turnbuckle at its ends, is the easiest way to obtain the necessary clamping pressure.
Vorteilhafterweise kann dann unter dem Spannschloß die Mantelfläche des Beschwerungsgewichts eben abgeflacht sein und im Kreise der Laschen eine mindestens der Länge des Spannschlosses entsprechende Lücke vorgesehen sein. Die Abflachung der Mantelfläche dient in diesem Fall der Bildung einer Vorzugsrichtung für die Verschraubung des Schlosses.The outer surface of the weight can then advantageously be placed under the turnbuckle just be flattened and at least one in the circle of the tabs Length of the turnbuckle corresponding gap may be provided. The flattening in this case, the lateral surface serves to form a preferred direction for the screw connection of the castle.

Die von oben beschickbare Waschmaschine 1 in Fig. 1 enthält einen Laugenbehälter 2,
der mit einer Antriebsvorrichtung 3 aus Motor 4, Riemen 5 und Riemenscheibe 6 besteht.
Die Riemenscheibe ist mit einer im Laugenbehälter 2 horizontal drehbar gelagerten
Wäschetrommel (hier nicht dargestellt) drehfest verbunden. Der Laugenbehälter 2
ist über Federn 7 im Gehäuse 8 der Waschmaschine 1 schwingend aufgehängt und
über Stoßdämpfer 9 zum Boden 10 des Gehäuses 8 abgestützt. An der dem Antrieb 3
gegenüberliegenden Bodenscheibe 11 des Laugenbehälters 2 ist ein Beschwerungsgewicht
12 befestigt, das einerseits als Gegengewicht zu der Masse der Antriebsvorrichtung
3 und andererseits als Dämpfungsmasse für das schwingende Laugenbehältersystem
dient.The washing machine 1 in FIG. 1, which can be loaded from above, contains a
In der in Fig. 2 dargestellten Ansicht auf die Bodenscheibe 11 ist die ringförmige
Struktur des Beschwerungsgewichts 12 erkennbar. Das Beschwerungsgewicht ist in
eine flache topfförmige Struktur der Bodenscheibe 11 eingelegt, deren schmale mantelseitige
Wandung aus Laschen 13 besteht, die auf einem Kreis zueinander beabstandet
angeordnet sind. Die Laschen 13 sind einstückiger Bestandteil der aus Kunststoff
gefertigten Bodenscheibe 11. An der durch die Einzelheit IV gekennzeichneten Position
ist im Kreis der Laschen eine Lücke 14 gelassen, an der eine Abflachung 15 des Beschwerungsgewichtes
12 gelegen ist. Sie dient als ebene Auflage für zwei jeweils am
Ende eines Spannbandes 16 angebrachte Spannböcke 17, die durch eine Schraube 18
unter Zug auf die Enden des Spannbandes 16 aufeinander zu gezogen werden.In the view of the
Aus dem in Fig. 3 dargestellten Schnitt durch die Bodenscheibe 11 und das Beschwerungsgewicht
12 entlang der Schnittlinie III-III in Fig. 2 ist erkennbar, daß das Beschwerungsgewicht
12 über eine Anlagefläche 19 mit der Bodenscheibe 11 Kontakt hat.
Diese Anlagefläche 19 ist Bestandteil eines von drei kreisförmig verteilten Buckeln 20
an der Bodenscheibe 11 um dem Beschwerungsgewicht 12 eine definierte Anlageposition
zu erteilen. Da die übrigen Flächen der Bodenscheibe 11 auf diese Weise ohne
Kontakt zum Beschwerungsgewicht 12 sind, werden Vibrationsgeräusche aus dieser
Anbindungsform vermieden.From the section shown in Fig. 3 through the
Die in Fig. 4 vergrößert dargestellte Einzelheit IV in Fig. 2 zeigt das Spannschloß des
Spannbandes 16 in allen Einzelheiten. An den Enden des Spannbandes 16 sind
Spannböcke 17 angebracht, die einerseits zum Halten des Schraubenkopfes 21 der
Schraube 18 und andererseits zum Halten der Schraubenmutter 22 für die Schraube 18
dienen. Die Spannböcke 17 gleiten beim Spannen der Schraube auf der Abflachung
15 des Beschwerungsgewichts 12, ohne die Schenkel 23 aus ihrer rechtwinkligen
Position zu bewegen.The detail IV shown in Fig. 4 enlarged in Fig. 2 shows the turnbuckle of
Die in Fig. 5 dargestellte Einzelheit V aus Fig. 3 zeigt die Position einer Lasche 13 und
des Spannbandes 16 vor dem Spannen durch das Spannschloß 17, 18, 21, 22. Daraus
ist deutlich zu erkennen, daß die schmale Mantelfläche 24 des Beschwerungsgewichtes
12 leicht geneigt ist. Der Neigungswinkel beträgt beispielsweise 2,5° und ist so eingestellt,
daß die Anlageseite 25 des Beschwerungsgewichts 12 einen größeren Durchmesser
hat als die der Anlageseite abgewandte Kreisfläche 26. Damit die Laschen 13
sich leicht gegen den Druck des Spannbandes 16 an die schmale Mantelfläche 24 des
Beschwerungsgewichts 12 anlegen, haben die Laschen 13 an ihrer Wurzel eine geringere
Dicke als an ihrem freien Ende. Einige der auf dem Kreis am Boden 11 angeordneten
Laschen weisen an ihrem freien Ende eine die Dicke des Spannbandes 16 überragende
Erhebung 27 auf. Diese Erhebungen 27 dienen dazu, ein Abrutschen des
Spannbandes 16 von den leicht geneigt anliegendne Laschen 13 zu verhindern.
Andere Laschen haben keine solche Erhebung, wie aus der Einzelheit X in Fig. 3 zu
erkennen ist.The detail V from FIG. 3 shown in FIG. 5 shows the position of a
In Fig. 6 ist die fertig montierte Situation entsprechend der in Fig. 5 dargestellten Einzelheit
gezeigt. Dabei drückt das Spannband 16 alle Laschen 13 auf die geneigte
Mantelfläche 24 des Beschwerungsgewichts 12, wodurch das Beschwerungsgewicht
einerseits kraftschlüssig durch den Spanndruck auf die Mantelfläche und andererseits
formschlüssig durch die Verringerung des Winkels zwischen der Anlagefläche 25 und
den Anlageflächen der Laschen 13 von 90° auf 87,5° (entsprechend der Nerigung von
2,5°). Das Profil der Laschen 13 ist - wie in Fig. 6 deutlich zu sehen ist - so gewählt,
daß die Laschen in ihrer Anlageposition mit ihren Außenflächen wiederum einen Winkel
von 90° zu der Anlageseite 25 des Beschwerungsgewichts 12 bilden. Dadurch ist
ebenfalls eine Verringerung der Gefahr des Abgleitens des Spannbandes 16 von den
Laschen 13 gegeben.In Fig. 6 the fully assembled situation corresponds to the detail shown in Fig. 5
shown. The
