Definitions
- the present invention relates to a device for damping vibrations of a tank in a washing machine and / or drying the laundry, as well as a machine equipped with at least one of these devices.
- a washing machine includes a drum containing the laundry, immersed in a tank and a drum drive device (or basket) rotating in this tank.
- a drum drive device or basket rotating in this tank.
- the mass of irregularly distributed laundry forms an imbalance which causes strong vibrations of the assembly.
- the tank - basket - drive device assembly is mounted mobile, suspended or placed (or both at the same time) on the machine structure .
- the first is to use one or more tube shock absorbers.
- These comprise a piston constituted by a cylindrical friction pad sliding in a smooth tube whose walls are greased.
- the linear friction force is given by the clamping pressure between the wiper and the tube.
- This piston is stretched between the body and the tank by means of silentblocs or rubber sleeves giving the shock absorber a certain degree of freedom, the tubes tilting in the direction of friction.
- this control of the dampings is really effective only in the plane perpendicular to the axis of rotation of the drum, this type of dampers not making it possible to absorb the displacement of the tank in the plane parallel to this axis of rotation. .
- shock absorbers minimizes the space required between the tank and the body, the connections made of rubber silentblocs do not allow their own damping and the assembly is relatively cost.
- the pistons age badly, the fat they contain flows to the bottom of the tube, they degrade and lose their characteristics.
- a third solution consists in using shock absorbers with thin plates and guided shoes.
- the plate is fixed to the tank and the pads are mounted on a rigid wire which is U-shaped, the base of which is enclosed in a rubber tunnel fixed to the base of the washing machine. Most of the friction is achieved by the shoe guided on the plate. The depreciation thus produced is far too rigid and is only carried out in one plane. On the other hand, the friction by rotation of the rigid wire fitted into the rubber tunnel secured to the base of the machine is poorly controlled.
- the deflections of the tank are damped in all directions and the friction force in the plane of the plate is a function of the materials used for the pads and the force of tightening applied by the spring wire.
- the cost price of such a device is lower than that of hydraulic shock absorbers or tubes.

- the reduction of vibrations of the whole machine allows a gain in acoustic comfort for the user.
- the cost price is lower than the device of the tube shock absorbers of the first solution mentioned and its reliability higher.
- FIG. 1 an example of a possible embodiment of a device according to the invention
- a damping means consists of a spring element, here a spring wire not shown in shape of U, the base of which is fixed to the movable element, that is to say the tank, and the two ends of the arms of which are each articulated on friction shoes, not shown.
- These pads are pressed on either side of the plate 6 by the clamping force of the spring wire
- These pads are guided on the plate 6 thanks, for example, to the flange 7 formed by the folding down on one of the faces of the plate 6 which delimits a corridor in which the shoe will slide. Only one shoe can be guided, the elastic rigidity of the spring wire guiding the other shoe. This linear depreciation constitutes the first degree of freedom of depreciation achieved by the invention.
- each of the pads on the plate is provided in its center with a cavity welcoming the ends of the spring wire and allowing it to pivot in this cavity.
- the ends of the spring wire exert pressure on each of the pads through these joints.
- the plate 6 is secured to the stationary part of the machine,
- the plate 6 is fixed to a spherical part 31 rotating around a first axis 32 and around a second axis not shown, for example, perpendicular to the previous one and to the plane of Figure 1.
- the spherical part is placed between two jaws 33,34 fixed for example on a base 35 fixed to the fixed or mobile part of the machine.
- a rod 36 passes through the jaws 33, 34 and the spherical part 31 along the first axis 32.
- the rod 36 is locked at a first end against a first jaw 33 by means of a crimping washer for example.
- a spring system 37 is placed for example between a washer fixed to the latter and the second jaw 34 so that the two jaws 33, 34 clamp the spherical part 31.
- a material 38 with a given coefficient of friction is placed between the jaws 33, 34 and the spherical part 31.
- Conical openings 39 are made in the spherical part 31 around the rod 36 from the axis of symmetry of the plate 6 so as to allow rotation of the spherical part 31 around the second axis not shown.
- the plate 6 can therefore rotate around the two aforementioned axes with a friction force, these two rotations constituting the two degrees of damping in rotation.
- Figure 1 shows a possibility of articulation with at least two degrees of freedom, but it is obvious that a device according to the invention using any other articulation of this type does not depart from the scope of the present invention.
- the damping element is here a plate, but any other type of damper such as, for example, pistons, plates with non-guided pads, friction tubes or springs, can be used in combination with a joint has at least two degrees of freedom without departing from the scope of the present invention.
- the damping device according to the invention can be mounted on the machine so that its damping means is fixed on the mobile part of the machine and its articulation on the stationary part or vice versa.
- the present invention applies to washing machines to be introduced from the top or front but can be extended to all machines undergoing vibrations due to the rotational movements of an irregularly distributed mass thereby having a so-called yaw movement and requiring a device for damping these vibrations.

Description
La présente invention concerne un dispositif amortisseur de vibrations d'une cuve dans une machine à laver et/ou à sécher le linge, ainsi qu'une machine équipée d'au moins un de ces dispositifs.The present invention relates to a device for damping vibrations of a tank in a washing machine and / or drying the laundry, as well as a machine equipped with at least one of these devices.
Une machine à laver le linge comporte un tambour contenant le linge, immergé dans une cuve et un dispositif d'entraînement du tambour (ou panier) en rotation dans cette cuve. Lorsque le tambour est entraîné en rotation, particulièrement lors de l'essorage, la masse de linge irrégulièrement répartie forme un balourd qui provoque des fortes vibrations de l'ensemble. Afin de diminuer la transmission de ces vibrations au reste de la structure de la machine, l'ensemble cuve - panier - dispositif d'entraînement est monté mobile, suspendu ou posé (ou bien les deux à la fois) sur la structure de la machine.A washing machine includes a drum containing the laundry, immersed in a tank and a drum drive device (or basket) rotating in this tank. When the drum is driven in rotation, particularly during spinning, the mass of irregularly distributed laundry forms an imbalance which causes strong vibrations of the assembly. In order to reduce the transmission of these vibrations to the rest of the machine structure, the tank - basket - drive device assembly is mounted mobile, suspended or placed (or both at the same time) on the machine structure .
Une mauvaise maîtrise de ces débattements a deux types de conséquences, acoustiques et mécaniques. Les vibrations transmises à la machine font vibrer l'habillage constitué de plaques fines qui sont autant de membranes vibrantes. D'autre part, les forces transmises à la machine provoquent une instabilité mécanique qui dégrade ses composants et peut aller jusqu'au déplacement de la machine.Poor control of these deflections has two types of consequences, acoustic and mechanical. The vibrations transmitted to the machine vibrate the covering made up of thin plates which are as many vibrating membranes. On the other hand, the forces transmitted to the machine cause mechanical instability which degrades its components and can go as far as moving the machine.
Pour limiter les débattements de la cuve par rapport au reste de la structure de la machine, on peut par exemple, augmenter l'inertie de la cuve grâce à des dispositifs de lestage intégrés ou fixés sur celle-ci, et/ou lier la cuve à la carrosserie par des amortisseurs fixés d'un côté à la structure immobile de la machine et de l'autre à la cuve. Dans ce dernier cas, plusieurs solutions sont proposées aux fabricants de machine à laver le linge.To limit the movements of the tank relative to the rest of the machine structure, it is possible, for example, to increase the inertia of the tank thanks to ballasting devices integrated or fixed on it, and / or to tie the tank to the bodywork by shock absorbers fixed on one side to the stationary structure of the machine and on the other to the tank. In the latter case, several solutions are offered to manufacturers of washing machines.
La première consiste à utiliser un ou plusieurs amortisseurs tubes. Ceux-ci comportent un piston constitué par un patin de frottement cylindrique coulissant dans un tube lisse dont les parois sont graissées. La force de frottement linéaire est donnée par la pression de serrage entre le frotteur et le tube. Ce piston est tendu entre la carrosserie et la cuve par l'intermédiaire de silentblocs ou de manchons en caoutchouc donnant à l'amortisseur un certain degré de liberté, les tubes s'inclinant dans la direction des frottements. Cependant, cette maîtrise des amortissements n'est réellement efficace que dans le plan perpendiculaire à l'axe de rotation du tambour, ce type d'amortisseurs ne permettant pas d'absorber le déplacement de la cuve dans le plan parallèle à cet axe de rotation. Si ce type d'amortisseurs permet de minimiser l'espace nécessaire entre la cuve et la carrosserie, les liaisons réalisées en silentblocs en caoutchouc ne permettent pas un amortissement qui leur soit propre et l'ensemble est d'un prix de revient relativement élevé. D'autre part, les pistons vieillissent mal, la graisse qu'ils contiennent coule au fond du tube, ils se dégradent et perdent leurs caractéristiques.The first is to use one or more tube shock absorbers. These comprise a piston constituted by a cylindrical friction pad sliding in a smooth tube whose walls are greased. The linear friction force is given by the clamping pressure between the wiper and the tube. This piston is stretched between the body and the tank by means of silentblocs or rubber sleeves giving the shock absorber a certain degree of freedom, the tubes tilting in the direction of friction. However, this control of the dampings is really effective only in the plane perpendicular to the axis of rotation of the drum, this type of dampers not making it possible to absorb the displacement of the tank in the plane parallel to this axis of rotation. . If this type of shock absorbers minimizes the space required between the tank and the body, the connections made of rubber silentblocs do not allow their own damping and the assembly is relatively cost. On the other hand, the pistons age badly, the fat they contain flows to the bottom of the tube, they degrade and lose their characteristics.
Une autre solution consiste à utiliser des amortisseurs hydraulique du type de ceux utilisés dans l'industrie de l'automobile. Leur amortissement est fonction de la vitesse de leur utilisation, ceci grâce aux changements des propriétés de l'huile du fait de la variation de température. L'inconvénient majeur de cet amortisseur est son prix de revient très élevé.Another solution is to use hydraulic shock absorbers of the type used in the automotive industry. Their damping is a function of the speed of their use, this thanks to the changes in the properties of the oil due to the temperature variation. The major drawback of this shock absorber is its very high cost price.
Une troisième solution consiste à utiliser des amortisseurs à plaque fine et à patins guidés. La plaque est fixée à la cuve et les patins sont montés sur un fil rigide qui est en forme de U dont la base est enserrée dans un tunnel en caoutchouc fixé à l'embase du lave-linge. L'essentiel du frottement est réalisé par le patin guidé sur la plaque. L'amortissement ainsi réalisé est beaucoup trop rigide et ne s'effectue que dans un plan. D'autre part, le frottement par rotation du fil rigide emmanché dans le tunnel en caoutchouc solidaire de l'embase de la machine est mal contrôlé.A third solution consists in using shock absorbers with thin plates and guided shoes. The plate is fixed to the tank and the pads are mounted on a rigid wire which is U-shaped, the base of which is enclosed in a rubber tunnel fixed to the base of the washing machine. Most of the friction is achieved by the shoe guided on the plate. The depreciation thus produced is far too rigid and is only carried out in one plane. On the other hand, the friction by rotation of the rigid wire fitted into the rubber tunnel secured to the base of the machine is poorly controlled.
Enfin, une quatrième solution proche de la précédente et permettant de résoudre un certain nombre des inconvénients cités ci-dessus, concerne les amortisseurs plaques. Ceux-ci comportent une large plaque fixée sur l'embase du lave-linge et qui est prise entre deux patins de frottement non guidés, solidaires de la cuve par l'intermédiaire d'un fil ressort qui est d'un côté articulé sur les patins et de l'autre solidaire de la cuve grâce à un dispositif pouvant pivoter par rapport à la cuve autour de son axe de fixation. Cette dernière caractéristique permet d'amortir par frottement les mouvements de la cuve par rapport à la machine dans la direction perpendiculaire au plan de la plaque. Ainsi, les débattements de la cuve sont amortis dans toutes les directions et la force de frottement dans le plan de la plaque est fonction des matériaux utilisés pour les patins et de l'effort de serrage appliqué par le fil ressort. Le prix de revient d'un tel dispositif est inférieur à celui des amortisseurs hydrauliques ou des tubes.Finally, a fourth solution close to the previous one and making it possible to solve a certain number of the drawbacks mentioned above, concerns the plate dampers. These comprise a large plate fixed on the base of the washing machine and which is taken between two non-guided friction pads, integral with the tank by means of a spring wire which is on one side articulated on the pads and the other secured to the tank by means of a device which can pivot relative to the tank around its fixing axis. This last characteristic makes it possible to dampen by friction the movements of the tank relative to the machine in the direction perpendicular to the plane of the plate. Thus, the deflections of the tank are damped in all directions and the friction force in the plane of the plate is a function of the materials used for the pads and the force of tightening applied by the spring wire. The cost price of such a device is lower than that of hydraulic shock absorbers or tubes.
Cependant, des inconvénients demeurent, qui sont l'encombrement de l'espace dû à la taille de la plaque et la manière dont les vibrations non amorties sont transmises à la structure de la machine. En effet, les efforts transmis à la structure sont toujours maximum, lorsque, par exemple, la cuve se déplace parallèlement aux plaques, l'effort transmis à la plaque est lui aussi dirigé dans la même direction, ce qui peut engendrer un déplacement de la machine et renvoie aux conséquences des débattements mal maîtrisés décrits au début du texte.However, drawbacks remain, which are the space requirement due to the size of the plate and the way in which the non-damped vibrations are transmitted to the structure of the machine. Indeed, the forces transmitted to the structure are always maximum, when, for example, the tank moves parallel to the plates, the force transmitted to the plate is also directed in the same direction, which can cause a displacement of the machine and refers to the consequences of the poorly controlled deflections described at the beginning of the text.
Une demande de brevet français FR-A- 2 374 457 présente un dispositif d'amortissement pour machine à laver ayant plus d'un degré de liberté.A French patent application FR-A-2 374 457 discloses a damping device for a washing machine having more than one degree of freedom.
Le dispositif selon la présente invention permet de s'affranchir des inconvénients des solutions proposées jusqu'à présent.The device according to the present invention overcomes the drawbacks of the solutions proposed so far.
A cet effet, le dispositif amortisseur de vibration selon l'invention est réalisé tel que décrit par la revendication 1.To this end, the vibration damping device according to the invention is produced as described by claim 1.
Les efforts sur les plaques peuvent être dirigés dans toutes les directions et les différents efforts de frottement peuvent être dosés indépendamment, cela permet de diminuer notablement les composantes horizontales des efforts au pied du lave-linge.The forces on the plates can be directed in all directions and the various friction forces can be dosed independently, this makes it possible to significantly reduce the horizontal components of the forces at the foot of the washing machine.
On peut ainsi équiper une machine munie d'un tel dispositif de roulettes non rétractables et éviter un ensemble mise-sur-roulettes complexe.It is thus possible to equip a machine provided with such a device with non-retractable rollers and avoid a complex set-on-rollers.
Le débattement des vibrations transmises à la cuve est diminué et avec lui l'espace nécessaire entre la cuve et l'habillage, d'où une diminution du prix de revient de la machine.The deflection of the vibrations transmitted to the tank is reduced and with it the space required between the tank and the covering, hence a reduction in the cost price of the machine.
La diminution des vibrations de l'ensemble de la machine permet un gain en confort acoustique pour l'utilisateur.The reduction of vibrations of the whole machine allows a gain in acoustic comfort for the user.
D'autre part, le prix de revient est inférieur au dispositif des amortisseurs tube de la première solution citée et sa fiabilité supérieure.On the other hand, the cost price is lower than the device of the tube shock absorbers of the first solution mentioned and its reliability higher.
L'invention sera mieux comprise et des avantages supplémentaires apparaîtront à la lecture de la description qui va suivre illustrée par la figure suivante :The invention will be better understood and additional advantages will appear on reading the description which follows, illustrated by the following figure:

Un exemple de mode de réalisation possible d'un dispositif selon l'invention est représenté en coupe selon l'axe de symétrie d'une plaque 6. Un moyen amortisseur est constitué d'un élément ressort, ici un fil ressort non représenté en forme de U dont la base est fixée sur l'élément mobile, c'est-à-dire la cuve, et dont les deux extrémités des bras sont montées chacune articulée sur des patins frotteurs non représentés. Ces patins sont plaqués de part et d'autre de la plaque 6 par l'effort de serrage du fil ressort Ces patins sont guidés sur la plaque 6 grâce, par exemple, au rebord 7 formé par le rabattement sur une des faces de la plaque 6 qui délimite un couloir dans lequel va coulisser le patin. Seul un patin peut être guidé, la rigidité élastique du fil ressort assurant le guidage de l'autre patin. Cet amortissement linéaire constitue le premier degré de liberté de l'amortissement réalisé par l'invention.An example of a possible embodiment of a device according to the invention is shown in section along the axis of symmetry of a plate 6. A damping means consists of a spring element, here a spring wire not shown in shape of U, the base of which is fixed to the movable element, that is to say the tank, and the two ends of the arms of which are each articulated on friction shoes, not shown. These pads are pressed on either side of the plate 6 by the clamping force of the spring wire These pads are guided on the plate 6 thanks, for example, to the
La face extérieure à la plaque de chacun des patins est munie en son centre d'une cavité accueillant les extrémités du fil ressort et permettant à celle-ci de pivoter dans cette cavité. Les extrémités du fil ressort exercent une pression sur chacun des patins par l'intermédiaire de ces articulations. La plaque 6 est solidaire de la partie immobile de la machine,The outside face of each of the pads on the plate is provided in its center with a cavity welcoming the ends of the spring wire and allowing it to pivot in this cavity. The ends of the spring wire exert pressure on each of the pads through these joints. The plate 6 is secured to the stationary part of the machine,
comme par exemple l'embase de celle-ci, par l'intermédiaire d'une articulation à au moins deux degrés de liberté.such as for example the base thereof, by means of an articulation with at least two degrees of freedom.
La plaque 6 est fixée à une partie sphérique 31 tournant autour d'un premier axe 32 et autour d'un deuxième axe non représenté, par exemple, perpendiculaire au précédent et au plan de la figure 1. La partie sphérique est placée entre deux mâchoires 33,34 fixées par exemple sur un socle 35 fixé à la partie fixe ou mobile de la machine. Une tige 36 traverse les mâchoires 33, 34 et la partie sphérique 31 suivant le premier axe 32. La tige 36 est bloquée à une première extrémité contre une première mâchoire 33 par l'intermédiaire d'une rondelle de sertissage par exemple. A l'autre extrémité de la tige 36, un système à ressort 37 est placé par exemple entre une rondelle fixée à celle-ci et la deuxième mâchoire 34 de façon à ce que les deux mâchoires 33, 34 serrent la partie sphérique 31. Une matière 38 à coefficient de frottement donné est placée entre les mâchoires 33, 34 et la partie sphérique 31. Des ouvertures coniques 39 sont réalisées dans la partie sphérique 31 autour de la tige 36 à partir de l'axe de symétrie de la plaque 6 de façon à permettre une rotation de la partie sphérique 31 autour du deuxième axe non représenté. La plaque 6 peut donc tourner autour des deux axes précités avec un effort de frottement, ces deux rotations constituant les deux degrés de l'amortissement en rotation.The plate 6 is fixed to a
La figure 1 représente une possibilité d'articulation à au moins deux degrés de liberté, mais il est bien évident qu'un dispositif selon l'invention utilisant tout autre articulation de ce type ne sort pas du cadre de la présente invention.Figure 1 shows a possibility of articulation with at least two degrees of freedom, but it is obvious that a device according to the invention using any other articulation of this type does not depart from the scope of the present invention.
D'autre part, l'élément amortisseur est ici une plaque, mais tout autre type d'amortisseur tel que, par exemple, des pistons, des plaques avec des patins non guidés, des tubes à frottement ou des ressorts, peut être utilisé en combinaison avec une articulation a au moins deux degrés de liberté sans sortir du cadre de la présente invention.On the other hand, the damping element is here a plate, but any other type of damper such as, for example, pistons, plates with non-guided pads, friction tubes or springs, can be used in combination with a joint has at least two degrees of freedom without departing from the scope of the present invention.
Le dispositif amortisseur selon l'invention peut être monté sur la machine de manière à ce que son moyen amortisseur soit fixé sur la partie mobile de la machine et son articulation sur la partie immobile ou inversement.The damping device according to the invention can be mounted on the machine so that its damping means is fixed on the mobile part of the machine and its articulation on the stationary part or vice versa.
La présente invention s'applique aux machines à laver le linge à introduire par le haut ou frontale mais peut être étendue à toutes machines subissant des vibrations dues aux mouvements de rotation d'une masse irrégulièrement répartie ayant de ce fait un mouvement dit de lacet et nécessitant un dispositif d'amortissement de ces vibrations.The present invention applies to washing machines to be introduced from the top or front but can be extended to all machines undergoing vibrations due to the rotational movements of an irregularly distributed mass thereby having a so-called yaw movement and requiring a device for damping these vibrations.
