Description

La présente invention concerne un lave-linge à cuve en matière synthétique.The present invention relates to a washing machine with a tub made of synthetic material.

Un lave-linge comprend habituellement une cuve qui reçoit un tambour à linge et supporte des systèmes de vidange de la cuve et d'entraînement de ce tambour en rotation. La cuve est souvent suspendue à la carrosserie du lave-linge par un ou plusieurs ressorts de traction et/ou des pieds élastiques amortisseurs. Ces ressorts de traction comprennent fréquemment des extrémités recourbées en crochets ou en boucles ouvertes d'attache, destinées à être accrochées dans des trous de suspension formés dans la cuve et dans la carrosserie, où ces crochets peuvent pivoter librement. Dans un lave-linge, l'espace libre qui sépare la cuve de la carrosserie est souvent faible, ce qui ne facilite pas une mise en place de ces ressorts dans la carrosserie lors d'une suspension de la cuve, lorsque ces ressorts se présentent dans des positions quelconques. En effet, il faut d'abord les mettre respectivement en position de montage et ensuite les accrocher dans les trous correspondants dans la carrosserie.A washing machine usually comprises a tub which receives a laundry drum and supports systems for emptying the tub and for driving this drum in rotation. The tank is often suspended from the washing machine body by one or more tension springs and / or elastic shock-absorbing feet. These tension springs frequently include ends bent in hooks or in open attachment loops, intended to be hung in suspension holes formed in the tank and in the bodywork, where these hooks can pivot freely. In a washing machine, the free space which separates the tank from the body is often small, which does not facilitate the installation of these springs in the body during a suspension of the tank, when these springs are present. in any position. Indeed, it is first necessary to put them respectively in the mounting position and then hang them in the corresponding holes in the body.

La présente invention ayant pour but d'éviter ces inconvénients, permet de réaliser un lave-linge à cuve en matière synthétique, suspendue dans une carrosserie, par un ou plusieurs ressorts de traction à extrémités recourbées en crochets ou en boucles ouvertes d'attache dont le montage est aisément et rapidement effectué aussi bien manuellement que mécaniquement.The aim of the present invention is to avoid these drawbacks and makes it possible to produce a washing machine with a tub of synthetic material, suspended in a bodywork, by one or more tension springs with ends curved in hooks or in open fastening loops, assembly is easily and quickly carried out both manually and mechanically.

Un lave-linge 1 réalisé selon l'invention, partiellement et schématiquement illustré dans la figure 1 comprend une carrosserie 2 dont la paroi frontale et la paroi de dessus sont enlevées et ne sont pas représentées, et une cuve 3 en m atière synthétique destinée à être introduite dans la carrosserie 2 et suspendue dans celle-ci au moyen de quatre ressorts de traction, deux ressorts frontaux de suspension 4 et deux ressorts arrière de suspension 5. Les ressorts de traction 4 et 5 ont des extrémités recourbées en crochets ou en boucles ouvertes d'attache 6. Les extrémités inférieures recourbées des ressorts de suspension frontaux 4 sont accrochées dans des alvéoles 7 des oreilles de suspension frontales 8 de la cuve 3, et les extrémités supérieures recourbées de ces ressorts frontaux 4 sont engagées dans des trous 9 des languettes frontales saillantes 10 de la carrosserie 2. Les extrémités inférieures recourbées des ressorts de suspension arrière 5 sont accrochées dans des alvéoles 11 des oreilles de suspension arrière 12 de la cuve 3 et les extrémités supérieures recourbées de ces ressorts arrière sont montées dans des trous 13 des languettes latérales arrière 14 de la carrosserie 2. Les oreilles de suspension frontales 8 et arrière 12 sont formées soit sur le corps de la cuve 3 soit sur les bords d'un couvercle 15 de cette cuve 3.A washing machine 1 produced according to the invention, partially and schematically illustrated in FIG. 1, comprises a body 2 whose front wall and top wall are removed and are not shown, and a tank 3 made of synthetic material intended for be introduced into the bodywork 2 and suspended therein by means of four tension springs, two front suspension springs 4 and two rear suspension springs 5. The tension springs 4 and 5 have ends bent in hooks or in open attachment loops 6. The curved lower ends of the front suspension springs 4 are hooked in cells 7 of the front suspension ears 8 of the tank 3, and the curved upper ends of these front springs 4 are engaged in holes 9 protruding front tabs 10 of the bodywork 2. The curved lower ends of the rear suspension springs 5 are hooked in cells 11 of the rear suspension lugs 12 of the tank 3 and the curved upper ends of these rear springs are mounted in holes 13 of the rear lateral tabs 14 of the bodywork 2. The front 8 and rear 12 suspension lugs are formed either on the body of the tank 3 or on the edges of a cover 15 of this tank 3.

Selon une caractéristique importante, dans le lave-linge 1, la cuve 3 comprend des oreilles de suspension 8 et 12 pourvues respectivement d'alvéoles 7, 11 qui remplissent dans une mise en place de la cuve 3 dans la carrosserie 2, deux fonctions: une fonction de maintien des ressorts de suspension 4 et 5 en position prête de montage et une fonction de suspension de la cuve 3 avec liberté d'oscillations, aux extrémités recourbées en crochets ou en boucles ouvertes d'attache 6 de ces ressorts de suspension 4 et 5.According to an important characteristic, in the washing machine 1, the tank 3 comprises suspension lugs 8 and 12 respectively provided with cells 7, 11 which fulfill, in an installation of the tank 3 in the bodywork 2, two functions: a function for holding the suspension springs 4 and 5 in the ready-to-assemble position and a function for suspending the tank 3 with freedom of oscillation, at the ends bent in hooks or in open attachment loops 6 of these suspension springs 4 and 5.

Dans l'exemple illustré aux figures 1 à 4, dans le lave-linge 1, les ressorts de suspension 4 et 5 ont des extrémités recourbées en crochets 6 d'une manière identique, et les oreilles de suspension 8 et 12 de la cuve comprennent des alvéoles 7 et 11 ayant une structure également identique pour recevoir ces extrémités identiques de ces ressorts. Cependant ces alvéoles 7 et 11 ont des orientations qui sont déterminées respectivement par celles de ces ressorts au moment de leur montage dans la carrosserie 2 lors d'une suspension de la cuve 3. En effet lors de leur montage, les ressorts de suspension 5 doivent être verticalement disposés et les alvéoles 11 des oreilles de suspension 12 ont alors une orientation verticale tandis que les ressorts de suspension 4 doivent avoir une position inclinée prédéterminée vis-à-vis de la verticale (figure 1) les alvéoles 7 des oreilles de suspension 8 ont alors une orientation également inclinée dans la même direction que celle de ces ressorts vis-à-vis de la verticale.In the example illustrated in Figures 1 to 4, in the washing machine 1, the suspension springs 4 and 5 have ends bent in hooks 6 in an identical manner, and the suspension lugs 8 and 12 of the tank comprise cells 7 and 11 having an equally identical structure for receiving these identical ends of these springs. However, these cells 7 and 11 have orientations which are determined respectively by those of these springs at the time of their mounting in the bodywork 2 during a suspension of the tank 3. In fact during their mounting, the suspension springs 5 must be vertically arranged and the cells 11 of the suspension lugs 12 then have a vertical orientation while the suspension springs 4 must have a predetermined inclined position with respect to the vertical (FIG. 1) cells 7 of the suspension lugs 8 then have an orientation also inclined in the same direction as that of these springs with respect to the vertical.

Pour simplifier la description, une extrémité d'un ressort de suspension 5 et une oreille de suspension 12 de la cuve 3 réalisée en matière synthétique destinée à recevoir cette extrémité de ce ressort de suspension 5 sont schématiquement illustrées dans les figures 2 à 4 et décrites seules ci-après.To simplify the description, one end of a suspension spring 5 and one suspension lug 12 of the tank 3 made of synthetic material intended to receive this end of this suspension spring 5 are schematically illustrated in FIGS. 2 to 4 and described only below.

Dans l'exemple illustré, l'extrémité du ressort de suspension 5 est recourbée en un crochet plat 6 dont les deux branches de longueurs inégales, une branche courte à extrémité libre 16 et une branche longue 17 attaché au ressort, se trouvent dans un même plan et sont reliées entre elles par une partie recourbée ou coude 18. L'oreille de suspension 12 de la cuve 3 est constituée par une languette à faces sensiblement parallèles 20, 21 sur laquelle est formée une alvéolle 11. L'alvéole 11 comprend dans sa partie supérieure un trou de suspension 22 ayant une dimension supérieure à la section transversale des branches 16, 17 et coude 18 du crochet 6 du ressort 5, et formé transversalement dans cette oreille, et dans sa partie inférieure d'une part une fente de maintien 23 ayant une dimension au moins égale ou légèrement supérieure à la section transversale des branches 16, 17 et coude 18 du crochet 6 du ressort 5, prolongeant radialement le trou 22 vers le bas, et formant avec ce trou un passage d'une hauteur au moins égale à la hauteur de la bra nche courte à extrémité libre 16 du crochet 6 du ressort 5, et d'autre part un appendice de maintien 24 perpendiculaire à l'oreille de suspension, prolongeant latéralement la fente de maintien 23 et ses parois respectivement par une rainure ouverte vers le haut 25 et par des parois 27, 28, 29 de cette rainure, et un ergot de serrage élastique 30 formé, sur une 27 des parois latérales de cet appendice 24 et en saillie dans la rainure ouverte 25 de celui-ci, et muni d'un bossage de retenue 31. Lors d'un engagement du crochet 6 du ressort de suspension 5 dans l'alvéole 11 de l'oreille de suspension 12, la branche courte à extrémité libre 16 de ce crochet 6 traverse l'ensemble "trou 22 et fente 23", entre dans la rainure ouverte 25 de l'appendice 24, franchit le bossage de retenue 31 au moment où une majeure partie de la branche longue 17 du crochet 6 est également entrée dans l'alvéole 11 (figure 4), et y reste coïncée par l'ergot de serrage 30 de manière que le crochet 6 et par conséquent le ressort de suspension 5 soit fermement maintenu en position. Etant donné que dans les alvéoles 11 des oreilles de suspension 12, la fente 23 et la rainure 25 de leur appendice 24 prolongent verticalement le trou de suspension 22, les ressorts de suspension 5 dont les crochets 6 sont engagés dans ces alvéoles à travers ces trous 22, fente 23 et rainure 25, sont maintenus en position verticale. Dans les alvéoles 7 des oreilles de suspension 8, la fente 23 et la rainure de leur appendice 24 prolongent obliquement le trou 22, les ressorts de suspension 4 dont les crochets 6 sont engagés dans ces alvéroles 7, sont maintenus en position inclinée.In the example illustrated, the end of the suspension spring 5 is bent into a flat hook 6, the two branches of unequal length, a short branch with free end 16 and a long branch 17 attached to the spring, are located in the same plane and are interconnected by a curved part or elbow 18. The suspension lug 12 of the tank 3 is constituted by a tongue with substantially parallel faces 20, 21 on which is formed a cell 11. The cell 11 comprises in its upper part a suspension hole 22 having a dimension greater than the cross section of the branches 16, 17 and elbow 18 of the hook 6 of the spring 5, and formed transversely in this ear, and in its lower part on the one hand a slot of support 23 having a dimension at least equal to or slightly greater than the cross section of the arms 16, 17 and elbow 18 of the hook 6 of the spring 5, extending the hole 22 downwards radially, and forming with this hole a p assage of a height at least equal to the height of the short bra nche with free end 16 of the hook 6 of the spring 5, and on the other hand a retaining appendage 24 perpendicular to the suspension lug, laterally extending the slot of holding 23 and its walls respectively by a groove open upwards 25 and by walls 27, 28, 29 of this groove, and an elastic clamping pin 30 formed, on one 27 of the side walls of this appendage 24 and projecting in the open groove 25 thereof, and provided with a retaining boss 31. When engaging the hook 6 of the suspension spring 5 in the socket 11 of the suspension ear 12, the short branch at the end free 16 of this hook 6 crosses the assembly "hole 22 and slot 23", enters the open groove 25 of the appendix 24, crosses the retaining boss 31 at the moment when a major part of the long branch 17 of the hook 6 has also entered the cell 11 (Figure 4), and remains there coincided by the clamping pin 30 so that the hook 6 and therefore the suspension spring 5 is firmly held in position. Since in the cells 11 of the suspension lugs 12, the slot 23 and the groove 25 of their appendage 24 extend the suspension hole 22 vertically, the suspension springs 5 whose hooks 6 are engaged in these cells through these holes 22, slot 23 and groove 25, are held in a vertical position. In the cells 7 of the suspension ears 8, the slot 23 and the groove of their appendage 24 obliquely extend the hole 22, the suspension springs 4, the hooks 6 of which are engaged in these cells 7, are held in the inclined position.

Selon l'invention, dans une opération de suspension de la cuve 3 dans la carrosserie 2 (figure 1), d'abord les ressorts de suspension 4 et 5 sont montés par leurs extrémités inférieures sur la cuve 3, ensuite l'ensemble "cuve 3 et ressorts 4, 5" est introduit par le haut du lave-linge dans la carrosserie 2, à travers l'espace occupé par la paroi supérieure de ce lave-linge 1, jusqu'à ce que les extrémités supérieures des ressorts de suspension 4 et 5 soient au niveau des trous 9 et 13 des languettes 10 et 14 de la carrosserie 2 dans lesquelles ces extrémités doivent être accrochées, puis les crochets constituant les extrémités supérieures de ces ressorts 4 et 5 sont engagés dans ces trous 9 et 13, et enfin la cuve 3 est relachée et sous l'effet de son poids qui est supérieur à la force de serrage des ergots 30 des alvéoles 7 et 11 sur les crochets 6 de ces ressorts de suspension, les crochets 6 se dégagent de ces ergots de serrage 30, quittent les rainures 25 de l'appendice 24 et les fentes 23 et entrent dans les trous de suspension 22 où les parties recourbées ou coudées 18 de ces crochets représentées en traits discontinus dans la figure 4 sont arrêtées par les parois de ces derniers trous 22. La cuve 3 est alors suspendue aux crochets 6 des extrémités inférieures de ces ressorts 4 et 5 tandis que les crochets des extrémités supérieures de ces ressorts sont retenues par les languettes 14 de la carrosserie 2. Au niveau des trous de suspension 22, ni les branches courtes 16 ni les branches longues 17 des crochets 6 de ces ressorts 4 et 5 ne sont immobilisées par les alvéoles 7 et 11, et les oreilles de suspension 8 et 12 peuvent osciller librement dans les crochets 6 des ressorts 4 et 5 ou inversement ces crochets 6 peuvent osciller librement dans les trous 22 de ces alvéoles 7 et 11.According to the invention, in an operation for suspending the tank 3 in the bodywork 2 (FIG. 1), first the suspension springs 4 and 5 are mounted by their lower ends on the tank 3, then the whole "tank 3 and springs 4, 5 "is introduced from the top of the washing machine into the bodywork 2, through the space occupied by the upper wall of this washing machine 1, until the upper ends of the suspension springs 4 and 5 are at the holes 9 and 13 of the tongues 10 and 14 of the body 2 in which these ends are to be hooked, then the hooks constituting the upper ends of these springs 4 and 5 are engaged in these holes 9 and 13, and finally the tank 3 is released and under the effect of its weight which is greater than the clamping force of the lugs 30 of the cells 7 and 11 on the hooks 6 of these suspension springs, the hooks 6 are released from these lugs tightening 30, leave the grooves 25 of the appendix 24 and the f entes 23 and enter the suspension holes 22 where the curved or bent parts 18 of these hooks shown in broken lines in Figure 4 are stopped by the walls of these latter holes 22. The tank 3 is then suspended from the hooks 6 of the ends lower of these springs 4 and 5 while the hooks of the upper ends of these springs are retained by the tongues 14 of the bodywork 2. At the suspension holes 22, neither the short branches 16 nor the long branches 17 of the hooks 6 of these springs 4 and 5 are not immobilized by the cells 7 and 11, and the suspension lugs 8 and 12 can oscillate freely in the hooks 6 of the springs 4 and 5 or conversely these hooks 6 can oscillate freely in the holes 22 of these cells 7 and 11 .

Dans une opération de suspension de la cuve 3, si les ressorts 4 et 5 ne sont pas maintenus en position de montage par les alvéoles 7 et 11, ces ressorts se présentent dans des positions quelconques autour des trous des oreilles de suspension de la cuve comme ceux habituellement retrouvés dans des lave-linge connus, et lors d'une mise en place des extrémités supérieures de ces ressorts 4 et 5 dans les trous 9 et 13 des languettes 10 et 14 de la carrosserie 2, il faut les chercher un à un dans l'espace exigü séparant la cuve 3 de la carrosserie 2, les mettre en bonne position de montage avant de pouvoir les accrocher dans ces trous 9 et 13 de ces languettes 10 et 14. L'opération de suspension de la cuve 3 devient ainsi délicate et longue et ne peut être excutée que manuellement. Quand les ressorts 4 et 5 sont préablement maintenus en bonne position de montage par les alvéoles 7 et 11, les extrémités supérieures de ces ressorts 4 et 5 peuvent alors se trouver toutes en vis-à-vis des trous respectifs 9 et 13 lorsque la cuve 3 introduite dans la carrosserie 2 se trouve à un niveau prédéterminé et la mise en place de ces ressorts qui consiste simplement à engager leurs crochets 6 dans ces trous, peut être facilement exécutée mécaniquement et simultanément, ce qui raccourcie d'une manière appréciable le temps exigé pour cette opération de suspension de la cuve 3.In a tank suspension operation 3, if the springs 4 and 5 are not held in the mounting position by the cells 7 and 11, these springs are in any position around the holes of the suspension ears of the tank as those usually found in known washing machines, and when placing the upper ends of these springs 4 and 5 in the holes 9 and 13 of the tongues 10 and 14 of the body 2, they must be sought one by one in the cramped space separating the tank 3 from the body 2, put them in the correct mounting position before they can be hung in these holes 9 and 13 of these tabs 10 and 14. The operation of suspending the tank 3 thus becomes delicate and long and can only be performed manually. When the springs 4 and 5 are previously held in the correct mounting position by the cells 7 and 11, the upper ends of these springs 4 and 5 can then be all opposite the respective holes 9 and 13 when the tank 3 introduced into the body 2 is at a predetermined level and the installation of these springs which consists simply in engaging their hooks 6 in these holes, can be easily executed mechanically and simultaneously, which appreciably shortens the time required for this tank suspension operation 3.

Par ailleurs, une mise en place des extrémités inférieures des ressorts 4 et 5 dans les alvéoles 7 et 11 des oreilles de suspension 8 et 12 de la cuve 3 qui consiste simplement à glisser les crochets 6 de ces ressorts 4 et 5 dans les alvéoles 11 à travers les trous 22-fentes 23 et rainures 25 jusqu'à leur blocage par les ergots de serrage élastique 30, peut également être exécuté mécaniquement et simultanément. Cet avantage permet de réduire encore le temps de mise en place de la cuve 3 dans la carrosserie 2.Furthermore, the lower ends of the springs 4 and 5 are placed in the cells 7 and 11 of the suspension lugs 8 and 12 of the tank 3 which simply consists in sliding the hooks 6 of these springs 4 and 5 in the cells 11 through the holes 22-slots 23 and grooves 25 until they are blocked by the clamping lugs elastic 30, can also be executed mechanically and simultaneously. This advantage makes it possible to further reduce the time for setting up the tank 3 in the bodywork 2.

Selon une première variante de réalisation représentée à la figure 5, dans les alvéoles 11 des oreilles de suspension 8 et 12, les appendices 24 formés sur l'une 20 de leurs faces sont prolongés à travers les fentes 23 sur leur autre face 21 par des appendices complémentaires 33 qui sont munis d'une rainure ouverte en bout et en haut 34. Ces appendices complémentaires 33 augmentent dans ces alvéoles 11 par les parois de leurs rainures 34, les surfaces d'immobilisation ou de maintien des crochets 6 des ressorts 4 et 5 engagés dans ces alvéoles.According to a first alternative embodiment shown in FIG. 5, in the cells 11 of the suspension lugs 8 and 12, the appendages 24 formed on one of their faces are extended through the slots 23 on their other face 21 by complementary appendages 33 which are provided with a groove open at the end and at the top 34. These complementary appendages 33 increase in these cells 11 by the walls of their grooves 34, the surfaces for immobilizing or holding the hooks 6 of the springs 4 and 5 engaged in these cells.

Selon une deuxième variante de réalisation illustrée dans la figure 6, dans chacune des alvéoles 11 des oreilles de suspension 8 et 12, l'ergot de serrage élastique simple 30 est remplacé par deux ergots de serrage élastique 35, 36 symétriques à l'axe de la rainure ouverte 25 de l'appendice 24 de cette alvéole 11. Ces ergots de serrage symétriques renforcent le maintien des crochets 6 des ressorts 4 et 5 dans les alvéoles 7 et 11 des oreilles de suspension 8, 12 de la cuve 3.According to a second variant embodiment illustrated in FIG. 6, in each of the cells 11 of the suspension lugs 8 and 12, the simple elastic clamping pin 30 is replaced by two elastic clamping pins 35, 36 symmetrical to the axis of the open groove 25 of the appendix 24 of this cell 11. These symmetrical clamping lugs reinforce the retention of the hooks 6 of the springs 4 and 5 in the cells 7 and 11 of the suspension lugs 8, 12 of the tank 3.

Une encoche 38 est de préférence formée dans la partie des parois de la rainure ouverte 25 qui sépare ces deux ergots de serrage symétriques 35, 36 pour augmenter l'élasticité de ces ergots.A notch 38 is preferably formed in the part of the walls of the open groove 25 which separates these two symmetrical clamping lugs 35, 36 to increase the elasticity of these lugs.

Les parois des oreilles 12 et celles 27, 28 des rainures 25 peuvent être évidées d'une manière connue pour faciliter le moulage et en particulier le refroidissement des lames du moule réalisant les rainures 25. Ces évidements ne doivent pas gêner ou empêcher une mise en place des ressorts de suspension 4 et 5.The walls of the ears 12 and those 27, 28 of the grooves 25 can be hollowed out in a known manner to facilitate molding and in particular the cooling of the blades of the mold making the grooves 25. These recesses must not hinder or prevent setting in place. places suspension springs 4 and 5.
