A closure piece (11-1) interacts with the nozzle (10) to divert its jet if the nozzle is not in a position defined by a sector of the cam. <IMAGE>

Description

La présente invention concerne une buse orientable destinée à envoyer de l'eau dans l'un ou l'autre d'une pluralité de bacs de produits de lavage d'une machine à laver.The present invention relates to a steerable nozzle intended to send water into one or the other of a plurality of detergent tanks of a washing machine.

Dans certaines machines à laver, on utilise pour envoyer de l'eau dans les bacs, une électrovanne par bac. Or, les électrovannes sont coûteuses. L'emploi d'une buse orientable pour envoyer de l'eau dans les bacs permet d'utiliser une seule électrovanne pour un nombre quelconque de bacs.In some washing machines, one solenoid valve is used to send water to the tanks. However, the solenoid valves are expensive. The use of an adjustable nozzle to send water into the tanks allows the use of a single solenoid valve for any number of tanks.

Une buse orientable classique est couplée à un palpeur qui est sollicité par un ressort vers une came circulaire entraînée en rotation par le programmateur de la machine à laver. La came comprend des secteurs de rayons différents pour orienter la buse vers les différents bacs.A conventional steerable nozzle is coupled to a feeler which is biased by a spring towards a circular cam driven in rotation by the programmer of the washing machine. The cam includes sectors with different radii to orient the nozzle towards the different tanks.

Pour que ce dispositif fonctionne correctement, il faut que la came soit munie de rampes de passage d'un secteur à un secteur de rayon plus grand. Un inconvénient de ces rampes est que le programmateur ne peut effectuer des pas de programme pendant les franchissements des rampes. Cet inconvénient est d'autant plus grave que les rampes doivent être de pente douce afin que le programmateur n'ait à exercer un couple trop important pour déplacer la buse, ce couple important pouvant à la longue détériorer le programmateur, la came, ou le système de couplage de la buse à la came.For this device to function correctly, the cam must be provided with ramps for passing from one sector to a sector of larger radius. A disadvantage of these ramps is that the programmer cannot perform program steps while crossing the ramps. This drawback is all the more serious since the ramps must be of a gentle slope so that the programmer does not have to exert too great a torque to move the nozzle, this significant torque being able in the long run to deteriorate the programmer, the cam, or the nozzle to cam coupling system.

La demande de brevet allemand 1 710 566 décrit un dispositif à buse évitant cet inconvénient. Ce dispositif utilise pour déplacer la buse un système à soufflet gonflé par la pression de l'eau allant vers la buse. Le dispositif est toutefois particulièrement encombrant pour obtenir un débattement adéquat de la buse.German patent application 1,710,566 describes a nozzle device avoiding this drawback. This device uses a bellows system inflated by the pressure of the water going to the nozzle to move the nozzle. The device is however particularly bulky to obtain an adequate clearance of the nozzle.

Un objet de la présente invention est de prévoir un dispositif à buse orientable particulièrement peu encombrant pouvant fonctionner correctement avec une came dépourvue de rampes.An object of the present invention is to provide a particularly space-saving steerable nozzle device which can function correctly with a cam without ramps.

Pour cela, un ressort est disposé de manière à solliciter le palpeur susmentionné vers une position de repos éloignée de la came. Une turbine hydraulique exploitant l'énergie du fluide s'écoulant vers la buse, est prévue pour déplacer la buse par un engrenage à l'encontre de la force exercée par le ressort. Lorsque la turbine est actionnée, la buse tourne à l'encontre de la force du ressort jusqu'à ce que le palpeur vienne en butée contre un secteur de la came.For this, a spring is arranged so as to urge the aforementioned probe to a rest position remote from the cam. A hydraulic turbine exploiting the energy of the fluid flowing towards the nozzle, is provided to move the nozzle by a gear against the force exerted by the spring. When the turbine is actuated, the nozzle rotates against the force of the spring until the probe comes into abutment against a sector of the cam.

Au repos, le palpeur n'est pas en contact avec la came, ce qui permet une rotation libre de cette dernière. Il n'est donc pas utile de prévoir des rampes sur la came.At rest, the probe is not in contact with the cam, which allows free rotation of the latter. It is therefore not useful to provide ramps on the cam.

La présente invention vise plus particulièrement un dispositif à buse orientable autour d'un axe perpendiculaire à la buse, comprenant une came pour déterminer par des secteurs correspondants plusieurs positions en rotation de la buse. Un moyen élastique est disposé de manière à solliciter la buse vers une position de repos de non-coopération avec la came. Un moteur hydraulique exploite la puissance du fluide s'écoulant vers la buse pour entraîner la buse à l'encontre du moyen élastique vers une position de coopération avec la came. Le moteur hydraulique comprend une turbine mue par le fluide s'écoulant vers la buse et entraînant la buse en rotation par un engrenage. Un levier palpeur est couplé à la buse et coopère avec la came pour déterminer les positions de la buse.The present invention relates more particularly to a device with a nozzle orientable about an axis perpendicular to the nozzle, comprising a cam for determining by corresponding sectors several rotational positions of the nozzle. An elastic means is arranged so as to urge the nozzle towards a rest position of non-cooperation with the cam. A hydraulic motor exploits the power of the fluid flowing towards the nozzle to drive the nozzle against the elastic means towards a position of cooperation with the cam. The hydraulic motor comprises a turbine driven by the fluid flowing towards the nozzle and driving the nozzle in rotation by a gear. A feeler lever is coupled to the nozzle and cooperates with the cam to determine the positions of the nozzle.

Selon un mode de réalisation de la présente invention, le levier est couplé à une poulie de la buse par un câble.According to an embodiment of the present invention, the lever is coupled to a pulley of the nozzle by a cable.

Selon un mode de réalisation de la présente invention, le dispositif comprend une pièce de déviation coopérant avec la buse pour dévier le jet fourni par la buse si cette-dernière n'est pas à une position déterminée par un secteur de la came.According to an embodiment of the present invention, the device comprises a deflection piece cooperating with the nozzle for deflecting the jet supplied by the nozzle if the latter is not at a position determined by a sector of the cam.

Selon un mode de réalisation de la présente invention, ledit levier est couplé à la pièce de déviation qui est librement articulée par rapport à l'axe de rotation de la buse et sollicitée élastiquement vers une position de déviation du jet, à l'encontre dudit moyen élastique.According to an embodiment of the present invention, said lever is coupled to the deflection piece which is freely articulated relative to the axis of rotation of the nozzle and resiliently biased towards a position for deflecting the jet, against said elastic means.

Selon un mode de réalisation de la présente invention, le levier est couplé par un câble à une poulie libre en rotation par rapport à la buse autour dudit axe, la pièce de déviation étant solidaire de la poulie et sollicitée vers la position de déviation par un ressort appuyant entre un doigt de la buse et une butée de la pièce de déviation.According to one embodiment of the present invention, the lever is coupled by a cable to a pulley free to rotate relative to the nozzle around said axis, the deflection piece being integral with the pulley and urged towards the deflection position by a spring pressing between a finger of the nozzle and a stop of the deflection piece.

Ces objets, caractéristiques et avantages ainsi que d'autres de la présente invention seront exposés en détail dans la description suivante de modes de réalisation particuliers faite en relation avec les figures jointes parmi lesquelles :

  • les figures 1A et 1B représentent deux positions d'un mode de réalisation schématique de dispositif à buse orientable selon l'invention ;
  • les figures 2A et 2B représentent deux vues en coupe d'un dispositif d'entraînement hydraulique de la buse des figures 1A et 1B ; et
  • les figures 3A et 3B représentent deux positions d'un autre mode de réalisation de dispositif à buse orientable selon l'invention.
These objects, characteristics and advantages as well as others of the present invention will be explained in detail in the following description of particular embodiments made in relation to the attached figures, among which:
  • FIGS. 1A and 1B represent two positions of a schematic embodiment of the device with an adjustable nozzle according to the invention;
  • Figures 2A and 2B show two sectional views of a hydraulic drive device of the nozzle of Figures 1A and 1B; and
  • FIGS. 3A and 3B represent two positions of another embodiment of the device with an adjustable nozzle according to the invention.

Dans les figures 1A et 1B, une buse orientable autour d'un axe A horizontal est couplée à un moteur hydraulique 12. Une conduite 14 alimente le moteur 12 en eau par l'intermédiaire d'une électrovanne 16. Le moteur 12 est tel que, lorsqu'il est alimenté par l'électrovanne 16, il entraîne la buse 10 dans le sens des aiguilles d'une montre, dans les figures.In FIGS. 1A and 1B, a nozzle orientable around a horizontal axis A is coupled to a hydraulic motor 12. A pipe 14 supplies the motor 12 with water via a solenoid valve 16. The motor 12 is such that , when powered by the solenoid valve 16, it drives the nozzle 10 clockwise in the figures.

La buse est munie d'une poulie 10-1 dans laquelle est fixé un câble 18 tendant, sous l'action d'un ressort 20, à déplacer la buse 10 dans le sens contraire des aiguilles d'une montre. Le câble 18 est fixé entre la poulie 10-1 et l'extrémité libre d'un levier 22 articulé à l'autre extrémité sur le bâti de la machine à laver. Le ressort 20 susmentionné est fixé entre l'extrémité libre du levier 22 et le bâti de la machine à laver de manière à tendre le câble 18.The nozzle is provided with a pulley 10-1 in which is fixed a cable 18 tending, under the action of a spring 20, to move the nozzle 10 anti-clockwise. The cable 18 is fixed between the pulley 10-1 and the free end of a lever 22 articulated at the other end on the frame of the washing machine. The aforementioned spring 20 is fixed between the free end of the lever 22 and the frame of the washing machine so as to tension the cable 18.

Dans la figure 1A, la buse 10 est dans une position de repos où le moteur 12 n'est pas alimenté et où le ressort 20 applique le levier 22 contre une butée 24 du bâti de la machine à laver. Le levier 22 comprend un palpeur 22-1 du côté opposé de la butée 24, qui est destiné à coopérer avec une came 26 entraînée en rotation par le programmateur (non représenté) de la machine à laver.In FIG. 1A, the nozzle 10 is in a rest position where the motor 12 is not supplied and where the spring 20 applies the lever 22 against a stop 24 of the frame of the washing machine. Lever 22 includes a feeler 22-1 on the opposite side of the stop 24, which is intended to cooperate with a cam 26 rotated by the programmer (not shown) of the washing machine.

La came 26 comprend, par exemple, des zones à quatre rayons différents pour définir la position de la buse 10 par rapport à quatre bacs 28 de produits de lavage. Les bacs 28 sont disposés sous la buse 10 et alignés selon le sens de balayage de la buse. Comme cela est représenté, les parois des bacs 28 peuvent comprendre des parties de guidage 28-1 disposées radialement par rapport à l'axe A de rotation de la buse.The cam 26 comprises, for example, zones with four different radii to define the position of the nozzle 10 relative to four tanks 28 of detergents. The tanks 28 are arranged under the nozzle 10 and aligned in the direction of scanning of the nozzle. As shown, the walls of the tanks 28 may include guide portions 28-1 arranged radially with respect to the axis A of rotation of the nozzle.

Dans la position de repos de la figure 1A, la buse 10 n'est pas orientée vers l'un des bacs 28. Ceci est dû au fait que l'on a besoin dans la position de repos d'un jeu entre le palpeur 22-1 et un secteur de plus grand rayon de la came 26 afin que la came 26 puisse tourner librement. Un secteur de plus grand rayon de la came 26 correspond au premier bac vers lequel la buse 10 doit être orientée, le bac de droite dans les figures.In the rest position of FIG. 1A, the nozzle 10 is not oriented towards one of the tanks 28. This is due to the fact that there is a need in the rest position for a clearance between the probe 22 -1 and a sector of larger radius of the cam 26 so that the cam 26 can rotate freely. A sector of larger radius of the cam 26 corresponds to the first tank towards which the nozzle 10 must be oriented, the right tank in the figures.

Lorsqu'il faut envoyer de l'eau vers l'un des bacs 28, un secteur de rayon correspondant se trouve face au palpeur 22-1, ce qui est déterminé par le programmateur, et l'électrovanne 16 est ouverte. Alors, le moteur hydraulique 12 est alimenté et entraîne la buse 10 dans le sens des aiguilles d'une montre. La buse 10 entraîne, par l'intermédiaire du câble 18, le levier 22 dans le sens des aiguilles d'une montre à l'encontre du ressort 20, jusqu'à ce que le palpeur 22-1 vienne en butée contre la came 26.When it is necessary to send water to one of the tanks 28, a sector of corresponding radius is located opposite the probe 22-1, which is determined by the programmer, and the solenoid valve 16 is open. Then, the hydraulic motor 12 is supplied and drives the nozzle 10 clockwise. The nozzle 10 drives, via the cable 18, the lever 22 in a clockwise direction against the spring 20, until the probe 22-1 abuts against the cam 26 .

La figure 1B représente la position des éléments de la figure 1A lorsque le palpeur 22-1 est en butée contre la came 26. Dans le cas représenté, la buse 10 se trouve en face du bac 28 de droite correspondant à un secteur de plus grand rayon de la came. Si l'électrovanne est coupée, les éléments retrouvent la position de la figure 1A. Et la came 26 pourra tourner librement pour faire correspondre avec le palpeur 22-1 un secteur de rayon différent correspondant à un autre bac 28.FIG. 1B represents the position of the elements of FIG. 1A when the probe 22-1 is in abutment against the cam 26. In the case shown, the nozzle 10 is located opposite the tank 28 on the right corresponding to a larger sector radius of the cam. If the solenoid valve is cut, the elements return to the position of the Figure 1A. And the cam 26 can rotate freely so as to match with the probe 22-1 a sector of different radius corresponding to another tank 28.

Bien entendu, si l'on alimente le moteur hydraulique 12 à la position de la figure 1A, la buse 10 commence par envoyer un jet d'eau en dehors des bacs 28. En outre, si la position à atteindre correspond à l'un des derniers bacs, la buse envoie de l'eau dans les bacs intermédiaires au cours de son basculement. Ceci n'est pas gênant dans certains cas car, d'une part, les bacs 28, le moteur 12 et la buse 10 sont disposés dans la cuve de la machine à laver, et donc l'eau passant à côté des bacs est récupérée dans la cuve ; d'autre part, les bacs sont destinés à être vidés de façon séquentielle, c'est-à-dire que, lorsque l'on veut vider un bac donné, les bacs précédents ont déjà été vidés et il n'est pas gênant que ceux-ci reçoivent de l'eau. Toutefois, le mode de réalisation des figures 3A et 3B, décrites ultérieurement, permet d'éviter que l'on envoie de l'eau dans des bacs intermédiaires.Of course, if the hydraulic motor 12 is supplied at the position of FIG. 1A, the nozzle 10 begins by sending a jet of water outside the tanks 28. In addition, if the position to be reached corresponds to one from the last tanks, the nozzle sends water to the intermediate tanks during its tilting. This is not annoying in certain cases because, on the one hand, the tanks 28, the motor 12 and the nozzle 10 are arranged in the tank of the washing machine, and therefore the water passing next to the tanks is recovered in the tank; on the other hand, the tanks are intended to be emptied sequentially, that is to say that, when one wants to empty a given tank, the previous tanks have already been emptied and it is not a problem that these receive water. However, the embodiment of FIGS. 3A and 3B, described later, makes it possible to avoid sending water into intermediate tanks.

La figure 2A représente une vue de côté en coupe d'un mode de réalisation de moteur hydraulique 12 et la figure 2B représente une vue en coupe selon la ligne II-II de la figure 2A. La buse 10 est formée par un tube coudé à 90°. Ce tube comporte une partie radiale à l'axe A, formant la sortie de la buse, et une partie axiale sur laquelle est fixée la poulie 10-1 susmentionnée.FIG. 2A represents a side view in section of an embodiment of hydraulic motor 12 and FIG. 2B represents a view in section along the line II-II of FIG. 2A. The nozzle 10 is formed by a tube bent at 90 °. This tube has a part radial to the axis A, forming the outlet of the nozzle, and an axial part to which the pulley 10-1 mentioned above is fixed.

Le moteur comprend un boîtier 12 en matière plastique dont une paroi, supérieure à la figure 2A, est traversée par la partie axiale de la buse 10. Cette partie axiale comprend, à l'intérieur du boîtier, une flasque 10-2 dentée engrénant avec un pignon 30. Le pignon 30 est solidaire d'un disque denté 30-1 engrénant avec un pignon 32. Le pignon 32 est solidaire d'une turbine à pales 34 mieux visible à la figure 2B. L'eau provenant du conduit 14 arrive, comme cela est représenté à la figure 2B, tangentiellement à la turbine 34. Pour améliorer l'efficacité de la turbine, le boîtier 12 présente au niveau de la turbine 34 une forme cylindrique de diamètre légèrement plus grand que celui de la turbine. La partie supérieure de la turbine 34, dans la figure 2A, est ouverte de manière que l'eau entraînant la turbine puisse s'évacuer et sortir par la buse 10.The motor comprises a plastic housing 12, a wall of which, superior to FIG. 2A, is crossed by the axial part of the nozzle 10. This axial part comprises, inside the housing, a toothed flange 10-2 meshing with a pinion 30. The pinion 30 is integral with a toothed disc 30-1 meshing with a pinion 32. The pinion 32 is integral with a blade turbine 34 best seen in Figure 2B. The water coming from the duct 14 arrives, as shown in FIG. 2B, tangentially to the turbine 34. To improve the efficiency of the turbine, the housing 12 has at the turbine 34 a cylindrical shape of slightly larger diameter larger than that of the turbine. The upper part of the turbine 34, in FIG. 2A, is open so that the water driving the turbine can be evacuated and come out through the nozzle 10.

L'homme du métier saura trouver divers modes de montage des éléments du moteur dans le boîtier 12.Those skilled in the art will be able to find various methods of mounting the elements of the engine in the housing 12.

Le boîtier 12 n'a pas besoin d'être étanche car l'ensemble de la buse 10 et du moteur se trouve dans la cuve de la machine à laver.The housing 12 does not need to be sealed because the assembly of the nozzle 10 and the motor is located in the tank of the washing machine.

Les figures 3A et 3B représentent deux positions d'un mode de réalisation de dispositif à buse orientable selon l'invention, permettant d'éviter d'envoyer de l'eau dans des bacs se trouvant dans la trajectoire d'un bac à atteindre par la buse. Les figures 3A et 3B correspondent respectivement, comme les figures 1A et 1B, à une position de repos et à une position de travail. Des mêmes éléments que dans les figures précédentes sont désignés par des mêmes références.FIGS. 3A and 3B represent two positions of an embodiment of a device with an adjustable nozzle according to the invention, making it possible to avoid sending water into tanks which are in the path of a tank to be reached by the nozzle. Figures 3A and 3B correspond respectively, as in Figures 1A and 1B, to a rest position and a working position. The same elements as in the previous figures are designated by the same references.

La buse 10 est toujours entraînée par le moteur hydraulique 12, mais, contrairement au dispositif des figures 1A et 1B, la poulie, désignée par la référence 11, est articulée en rotation autour de l'axe A par rapport à la buse 10. Une pièce de déviation 11-1 est solidaire de la poulie 11. Au repos (figure 3A), cette pièce de déviation s'étend parallèlement à la buse 10 depuis une zone périphérique de la poulie 11, du côté de la came 26, et comprend une partie perpendiculaire, ci-après appelée déviateur 11-2, venant devant la sortie de la buse 10. La buse 10 comprend un doigt 10-2 s'étendant perpendiculairement à la buse du côté de la pièce de déviation 11-1. Un ressort 36 appuie entre le doigt 10-2 et le fond d'un logement de la pièce d'obturation 11-1. Ce logement est délimité par la piece 11-1 elle-même et une partie, ci-après butée 11-3, s'étendant d'abord perpendiculairement à la pièce 11-1 puis parallèlement en direction du doigt 10-2.The nozzle 10 is still driven by the hydraulic motor 12, but, unlike the device in FIGS. 1A and 1B, the pulley, designated by the reference 11, is articulated in rotation around the axis A relative to the nozzle 10. A deflection piece 11-1 is integral with the pulley 11. At rest (FIG. 3A), this deflection piece extends parallel to the nozzle 10 from a peripheral zone of the pulley 11, on the side of the cam 26, and comprises a perpendicular part, hereinafter called deflector 11-2, coming in front of the outlet of the nozzle 10. The nozzle 10 comprises a finger 10-2 extending perpendicularly to the nozzle on the side of the deflection piece 11-1. A spring 36 presses between the finger 10-2 and the bottom of a housing of the closure part 11-1. This housing is delimited by the part 11-1 itself and a part, hereinafter abutment 11-3, extending first perpendicularly to the part 11-1 then parallel in the direction of the finger 10-2.

Avec cette configuration, la pièce de déviation 11-1 est en permanence sollicitée, par le ressort 36, vers une position de déviation (visible à figure 3A) où le déviateur 11-2 est devant la sortie de la buse 10. Comme il est nécessaire d'avoir un débit d'eau pour que le moteur hydraulique 12 entraîne la buse 10, le déviateur 11-2 est en fait tel que, plutôt que d'obturer la buse 10, il dévie le jet en dehors des bacs 28, c'est-à-dire vers le cuve de la machine à laver, par exemple perpendiculairement à la buse 10.With this configuration, the deflection piece 11-1 is permanently biased, by the spring 36, towards a deflection position (visible in FIG. 3A) where the deflector 11-2 is in front of the outlet of the nozzle 10. As it is necessary to have a flow of water so that the hydraulic motor 12 drives the nozzle 10, the deflector 11-2 is in fact such that, rather than closing the nozzle 10, it deflects the jet outside of the tanks 28, that is to say towards the tank of the washing machine, for example perpendicular to the nozzle 10.

Dans la position de la figure 3B, la buse 10 alimente en eau l'un des bacs 28. Pour atteindre cette position, un secteur adéquat de la came 26 est placé, dans la position de repos de la figure 3A, en face du palpeur 22-1, et on alimente le moteur 12 en ouvrant la vanne 16. La buse 10 fournit un jet d'eau qui est dévié vers la cuve par le déviateur 11-2, et la buse 10 est entraînée dans le sens des aiguilles d'une montre par le moteur 12. La buse 10 entraîne la pièce 11-1 par l'intermédiaire du doigt 10-2 appuyant sur le ressort 36, de manière que le déviateur 11-2 est toujours en face de la buse. La poulie 11 entraîne en même temps le levier 22 vers la came 26 par l'intermédiaire du câble 18. Pour obtenir ce résultat, la force du ressort 36 est bien entendu supérieure à la force du ressort 20 transmise par le câble 18.In the position of FIG. 3B, the nozzle 10 supplies water to one of the tanks 28. To reach this position, a suitable sector of the cam 26 is placed, in the rest position of FIG. 3A, opposite the probe. 22-1, and the motor 12 is fed by opening the valve 16. The nozzle 10 provides a jet of water which is deflected towards the tank by the diverter 11-2, and the nozzle 10 is driven in the direction of the needles d 'a watch by the motor 12. The nozzle 10 drives the part 11-1 by means of the finger 10-2 pressing on the spring 36, so that the deflector 11-2 is always opposite the nozzle. The pulley 11 simultaneously drives the lever 22 towards the cam 26 via the cable 18. To obtain this result, the force of the spring 36 is of course greater than the force of the spring 20 transmitted by the cable 18.

Lorsque le palpeur 22-1 rencontre la came 26, la pièce de déviation 11-1 se trouve bloquée mais la buse 10 continue à tourner dans le sens des aiguilles d'une montre en comprimant le ressort 36 avec le doigt 10-2 jusqu'à ce que ce dernier vienne en butée sur la butée 11-3. La buse 10 se dégage ainsi du déviateur et envoie un jet d'eau vers le bac 28 souhaité. Chaque secteur de la came 26 est choisi pour bloquer la pièce de déviation 11-1 de manière que la buse 10, en se dégageant du déviateur 11-2, alimente seulement le bac 28 correspondant.When the probe 22-1 meets the cam 26, the deflection piece 11-1 is blocked but the nozzle 10 continues to rotate clockwise by compressing the spring 36 with the finger 10-2 until the latter comes into abutment on the stop 11-3. The nozzle 10 thus emerges from the diverter and sends a jet of water to the desired tank 28. Each sector of the cam 26 is chosen to block the deflection piece 11-1 so that the nozzle 10, by disengaging from the deflector 11-2, feeds only the corresponding tank 28.

De nombreuses variantes et modifications de la présente invention apparaîtront à l'homme du métier. Par exemple, il pourra remplacer le câble 18 par une biellette.Many variants and modifications of the present invention will appear to those skilled in the art. For example, it can replace the cable 18 with a link.
