Abstract

The cleaner has a suction/pressure housing (11) with an intake (12). The intake is situated in a plane parallel to the surface being cleaned and at a short distance from the surface. A pressure outlet (13) is connected to a detachable debris collector (17). The housing contains an ejector with a nozzle (14) connected to a pressurised water source, and a Venturi diffusor (15). The ejector is connected to the pressurised water source by a pipe of which part is formed by a corrugated section (10). The water flow through it and is pulsed to produce an alternating expansion and retraction of the corrugated section. This causes the cleaner housing to advance over the surface being cleaned.

Description

La présente invention se rapporte au nettoyage de piscines, bassins, spas ou analogues. En particulier, l'invention concerne un appareil de nettoyage automatique du fond et des parois d'une piscine.The present invention relates to the cleaning of swimming pools, basins, spas or the like. In particular, the invention relates to an automatic device for cleaning the bottom and walls of a swimming pool.

Pour conserver une eau claire, il est indispensable de nettoyer la piscine régulièrement. A cet effet, il existe plusieurs types d'appareils que l'on peut globalement classer en quatre catégories :

  • Les appareils intégrés à la structure de la piscine : ils consistent à mettre en suspension les débris divers de sorte que ces derniers soient ensuite aspirés par les dispositifs de filtration de la piscine. Ces appareils sont automatiques et efficaces, mais relativement coûteux et doivent être prévus à la construction de la piscine ;
  • les appareils autonomes où robots : il s'agit de petites unités autonomes qui se déplacent dans le fond et sur les parois de la piscine en filtrant l'eau. Ces unités, mues électriquement, sont autonomes et indépendantes du dispositif de filtration de la piscine, mais elles sont relativement coûteuses et peu fiables en raison de leur complexité.
  • les aspirateurs asservis au dispositif de filtration de la piscine, tels que celui représenté schématiquement sur la figure 1. Le circuit d'aspiration de la piscine P comprenant une bonde de fond 1, des goulottes d'aspiration et d'écrémage en surface ou skimmers 2, une pompe 3, un filtre 4, une bouche de refoulement 5 et une conduite 6 reliant les différents éléments entre eux, l'aspirateur 7 est relié par un tuyau souple 8 du type à paroi en accordéon à l'un des skimmers 2. La bonde de fond 1 et les skimmers non utilisés doivent être obturés pendant le fonctionnement de l'aspirateur 7. L'aspirateur 7 se déplace par à-coups soit grâce à une turbine qui entraîne des roues ou des patins, soit du fait du phénomène de constriction-étirement périodique dudit tuyau, ces à-coups étant provoqués par un dispositif d'interruption cyclique du débit d'eau aspiré qui crée une forte dépression.
To maintain clear water, it is essential to clean the pool regularly. For this purpose, there are several types of devices that can be broadly classified into four categories:
  • The devices integrated into the pool structure: they consist of suspending various debris so that they are then sucked in by the pool's filtration devices. These devices are automatic and efficient, but relatively expensive and must be provided for the construction of the pool;
  • autonomous devices or robots: these are small autonomous units that move at the bottom and on the walls of the pool by filtering the water. These electrically powered units are autonomous and independent of the pool filtration system, but they are relatively expensive and unreliable due to their complexity.
  • vacuum cleaners slaved to the swimming pool filtration device, such as that shown schematically in FIG. 1. The suction circuit of the swimming pool P comprising a bottom drain 1, suction and skimming spouts on the surface or skimmers 2, a pump 3, a filter 4, a discharge mouth 5 and a pipe 6 connecting the different elements together, the vacuum cleaner 7 is connected by a flexible pipe 8 of the accordion-wall type to one of the skimmers 2. The bottom drain 1 and the unused skimmers must be closed during the operation of the vacuum cleaner 7. The vacuum cleaner 7 moves by at - cuts either thanks to a turbine which drives wheels or skids, or because of the phenomenon of periodic constriction-stretching of said pipe, these jerks being caused by a device for cyclic interruption of the flow of water sucked which creates a strong depression.

Ces aspirateurs sont de conception simple et peu coûteux. Toutefois, ils présentent de nombreux inconvénients.These vacuum cleaners are simple and inexpensive in design. However, they have many disadvantages.

La bonde de fond et les skimmers non concernés par l'aspiration devant être obturés, le recyclage d'eau effectué par ces derniers en surface et au fond de la piscine est supprimé ou fortement réduit pendant l'utilisation de l'aspirateur.The bottom drain and the skimmers not affected by the suction having to be closed, the recycling of water carried out by them on the surface and at the bottom of the pool is eliminated or greatly reduced during the use of the vacuum cleaner.

Il faut amorcer l'aspiration en remplissant d'eau tout le circuit. Par suite, il est nécessaire de surveiller le fonctionnement de l'aspirateur afin de vérifier qu'il ne se désamorce pas, ce qui peut arriver au cours de ses déplacements.Aspiration must be started by filling the entire circuit with water. As a result, it is necessary to monitor the operation of the vacuum cleaner to verify that it does not defuse, which can happen during its movements.

Les débris sont entraînés dans le pré-filtre du skimmer utilisé et , pour partie, dans la pompe 3 et le filtre 4. Ainsi, on encrasse les pré-filtres et filtres, d'où des risques de colmatage de ces derniers, ainsi que de cavitation et de désamorçage de la pompe. Ces aspirateurs ne sont par conséquent pas pratiques ni simple à utiliser.The debris is entrained in the pre-filter of the skimmer used and, in part, in the pump 3 and the filter 4. Thus, the pre-filters and filters are clogged, hence the risk of clogging of the latter, as well as pump cavitation and defusing. These vacuum cleaners are therefore not practical or easy to use.

Enfin, pour les appareils qui se déplacent par interruption de l'aspiration, les à-coups provoqués de manière cyclique dans le tuyau reliant l'aspirateur au skimmer sont transmis à l'ensemble de l'installation et risquent, à la longue, d'endommager notamment la pompe du circuit d'aspiration.

  • La dernière catégorie de appareils de nettoyage est constituée par des appareils fonctionnant en refoulement selon le principe de l'éjecteur, tel que celui décrit dans le document FR-2-586 051 délivré au nom du Demandeur.
Finally, for devices which move by interruption of the suction, the jolts caused cyclically in the pipe connecting the vacuum cleaner to the skimmer are transmitted to the entire installation and risk, in the long run, of '' Damage in particular the suction circuit pump.
  • The last category of cleaning devices consists of devices operating in discharge according to the ejector principle, such as that described in document FR-2-586 051 issued in the name of the Applicant.

L'appareil décrit dans ce document comporte un carter muni d'une bouche d'aspiration située à faible distance de la surface à nettoyer. Cet appareil est lesté de manière appropriée pour que, tout au long de son déplacement, la bouche d'aspiration reste au plus près de la surface à nettoyer. Toute l'eau refoulée par la bouche de refoulement de la piscine est disponible pour le fonctionnement de l'éjecteur, le jet assurant à la fois l'aspiration des débris et le déplacement de l'appareil dans la piscine. Il est de conception simple et peu coûteux, et permet de résoudre les inconvénients des aspirateurs qui fonctionnent en aspiration.The device described in this document comprises a housing provided with a suction mouth located a short distance from the surface to be cleaned. This device is weighted so suitable so that, throughout its movement, the suction mouth remains as close as possible to the surface to be cleaned. All the water discharged from the pool discharge mouth is available for the operation of the ejector, the jet ensuring both the suction of debris and the movement of the device in the pool. It is simple and inexpensive in design and overcomes the drawbacks of vacuum cleaners that operate on suction.

Mais cet appareil présente tout de même quelques inconvénients. En effet, son lest lui permet uniquement de se déplacer sur le fond de la piscine ou sur des parois peu pentues. Par exemple, il lui est impossible de nettoyer les parois verticales. De plus, il présente une capacité peu importante de collecte et de stockage des débris.But this device still has some drawbacks. Indeed, its ballast only allows it to move on the bottom of the pool or on slightly sloping walls. For example, he cannot clean the vertical walls. In addition, it has a low capacity for collecting and storing debris.

Il existe encore d'autres appareils qui fonctionnent en refoulement. Mais leur déplacement est obtenu par des dispositifs (notamment turbine ou jet d'eau sous pression) qui prélèvent constamment une partie de l'eau fournie à la buse de l'éjecteur, ce qui diminue fortement le rendement de l'appareil. C'est pourquoi certains de ces appareils doivent être connectés à un surpresseur pour pouvoir fonctionner. Ces appareils sont également lestés et ne peuvent pas se déplacer sur les parois sensiblement verticales. Ils sont plus complexes que l'appareil cité dans le document FR-2-586 051 et sont moins fiables et plus coûteux que ce dernier.There are still other devices that operate in backflow. However, their displacement is obtained by devices (in particular turbine or pressurized water jet) which constantly draw off part of the water supplied to the nozzle of the ejector, which greatly reduces the efficiency of the device. This is why some of these devices must be connected to a booster to operate. These devices are also weighted and cannot move on the substantially vertical walls. They are more complex than the device cited in document FR-2-586 051 and are less reliable and more expensive than the latter.

La présente invention vise à remédier les inconvénients des appareils décrits ci-dessus en proposant un appareil fonctionnant en refoulement de conception simple, qui soit fiable, qui permette de nettoyer notamment le fond et les parois sensiblement verticales de la piscine, qui ne nécessite pas pour se déplacer de prélèvement continu de l'eau fournie à l'éjecteur, de sorte à pouvoir fonctionner automatiquement en étant uniquement connecté à une bouche de refoulement de la piscine.The present invention aims to remedy the drawbacks of the devices described above by proposing a device operating in discharge of simple design, which is reliable, which makes it possible in particular to clean the bottom and the substantially vertical walls of the swimming pool, which does not require for move from continuous sampling of the water supplied to the ejector, so that it can operate automatically while being only connected to a discharge opening in the swimming pool.

A cet effet, l'invention a pour objet un appareil de nettoyage automatique notamment d'une piscine, comprenant :

  • un corps d'aspiration-refoulement présentant un orifice ou bouche d'aspiration disposé dans un plan sensiblement parallèle à la surface à nettoyer, à une faible distance de cette surface, et un orifice de refoulement ;

    caractérisé en ce que ledit éjecteur est disposé dans le corps et la buse est susceptible d'être reliée notamment à une bouche de refoulement de la piscine par un conduit dont une partie est formée par un tuyau souple à paroi accordéon, et en ce qu'il comporte un moyen de propulsion constitué par un dispositif pour créer entre ladite bouche de refoulement et ladite buse un échappement momentané et répété, vers l'extérieur, de l'eau sous pression dudit conduit, en sorte de créer, à la manière connue, un déplacement de l'appareil par constriction-étirement répété dudit tuyau souple.
To this end, the subject of the invention is an automatic cleaning device in particular for a swimming pool, comprising:
  • a suction-discharge body having a suction orifice or mouth disposed in a plane substantially parallel to the surface to be cleaned, at a short distance from this surface, and a discharge orifice;

La figure 1 a été décrite dans le préambule de la description en référence à l'art antérieur.Figure 1 has been described in the preamble of the description with reference to the prior art.

La figure 2 représente la même piscine P équipée d'un appareil de nettoyage 9 selon l'invention. Les éléments communs aux figures 1 et 2 portent sur la figure 2 les mêmes références que sur la figure 1.FIG. 2 represents the same swimming pool P equipped with a cleaning device 9 according to the invention. The elements common to Figures 1 and 2 have the same references in Figure 2 as in Figure 1.

A la différence de l'aspirateur 7 de l'art antérieur, qui est connecté au skimmer 2, l'appareil 9 selon l'invention est relié à la bouche de refoulement 5 par un tuyau souple 10 du type connu à paroi en accordéon. Le tuyau 10 est de grande longueur, à savoir de longueur au moins supérieure à la plus grande dimension de la piscine.Unlike the vacuum cleaner 7 of the prior art, which is connected to the skimmer 2, the device 9 according to the invention is connected to the discharge mouth 5 by a flexible pipe 10 of the known type with an accordion wall. The pipe 10 is of great length, namely of length at least greater than the largest dimension of the swimming pool.

L'appareil 9 est représenté en détails sur les figures 3 à 5. Il comprend un corps d'aspiration-refoulement 11 présentant un orifice ou bouche d'aspiration 12 et un orifice de refoulement 13, un éjecteur disposé dans ledit corps 11 et comportant une buse motrice 14 et un diffuseur à venturi 15, un conduit rigide 16 d'alimentation de la buse 14 en eau sous pression, un réceptacle à débris 17, une collerette ou jupe souple 18 et une vanne de décharge cyclique 19.The device 9 is shown in detail in Figures 3 to 5. It comprises a suction-discharge body 11 having a suction orifice or mouth 12 and a discharge orifice 13, an ejector disposed in said body 11 and comprising a driving nozzle 14 and a venturi diffuser 15, a rigid duct 16 for supplying the nozzle 14 with pressurized water, a debris receptacle 17, a flexible flange or skirt 18 and a cyclic discharge valve 19.

Le corps 11 est formé, dans le mode de réalisation représenté, par un conduit cylindrique d'axe vertical dont la paroi est localement déformée pour constituer le diffuseur 15. L'extrémité inférieure du conduit cylindrique forme la bouche d'aspiration 12 au voisinage de laquelle est disposée la collerette 18. L'extrémité supérieure dudit conduit forme l'orifice de refoulement 13 au droit duquel est monté le réceptacle à débris 17. Une petite fenêtre d'aspiration latérale 20 est ménagée sur le corps 11, au droit de la collerette 18.The body 11 is formed, in the embodiment shown, by a cylindrical duct with a vertical axis, the wall of which is locally deformed to form the diffuser 15. The lower end of the cylindrical duct forms the suction mouth 12 in the vicinity of which is arranged the flange 18. The upper end of said conduit forms the discharge orifice 13 to the right of which is mounted the debris receptacle 17. A small side suction window 20 is formed on the body 11, in line with the flange 18.

Le conduit 16 est coudé et comprend une partie 16a d'axe horizontal H perpendiculaire à l'axe du corps 11 et pénétrant dans ce dernier et une partie 16b d'axe incliné I (figure 7).The conduit 16 is bent and comprises a part 16a with a horizontal axis H perpendicular to the axis of the body 11 and penetrating into the latter and a part 16b with an inclined axis I (FIG. 7).

Le tuyau souple 10 est raccordé par tous moyens appropriés au conduit 16b.The flexible hose 10 is connected by any suitable means to the conduit 16b.

La buse 14 est agencée verticalement, coaxialement au corps 11 et latéralement au conduit d'alimentation 16a, et définit un ajutage horizontal. La section de la buse 14 va en se rétrécissant progressivement depuis le conduit 16a jusqu'à l'ajutage qui définit une sortie étroite générant un jet d'eau d'axe vertical.The nozzle 14 is arranged vertically, coaxially with the body 11 and laterally with the supply duct 16a, and defines a horizontal nozzle. The section of the nozzle 14 tapers progressively from the duct 16a to the nozzle which defines a narrow outlet generating a water jet with a vertical axis.

La section du conduit 16 est par exemple de l'ordre de la moitié de celle du corps 11.The section of the duct 16 is for example of the order of half that of the body 11.

Par ailleurs, le conduit 16 se prolonge en dehors du corps 11, à l'opposé de la partie 16b, par une partie 16c munie de ladite vanne de décharge cyclique 19.Furthermore, the conduit 16 is extended outside the body 11, opposite the part 16b, by a part 16c provided with said cyclic discharge valve 19.

Le dif fuseur 15 présente un col 15a situé sensiblement au droit de l'ajutage de la buse 14.The dif fuseur 15 has a neck 15a located substantially in line with the nozzle of the nozzle 14.

Le réceptacle à débris 17 est amovible et de structure ajourée. Il fait office de filtre laissant passer l'eau provenant de l'orifice de sortie 13 tout en retenant les débris entraînés.The debris receptacle 17 is removable and of openwork structure. It acts as a filter allowing the water coming from the outlet orifice 13 to pass while retaining the entrained debris.

La vanne de décharge cyclique 19 est représentée en éclaté sur la figure 5.The cyclic discharge valve 19 is shown in exploded view in FIG. 5.

Le prolongement 16c du conduit 16 est cylindrique et comporte un fond circulaire ajouré 21 dont le centre est muni d'un axe 22 porteur d'une turbine 23.The extension 16c of the conduit 16 is cylindrical and has a perforated circular bottom 21, the center of which is provided with an axis 22 carrying a turbine 23.

Au voisinage du fond ajouré 21, le conduit 16c comporte deux lumières symétriques 24.In the vicinity of the perforated bottom 21, the duct 16c comprises two symmetrical openings 24.

La turbine 23 est formée par un manchon cylindrique, dit manchon intérieur 25, qui chapeaute le prolongement 16c. Le diamètre intérieur du manchon 25 est légèrement supérieur au diamètre extérieur du conduit 16c.The turbine 23 is formed by a cylindrical sleeve, called the inner sleeve 25, which caps the extension 16c. The inside diameter of the sleeve 25 is slightly greater than the outside diameter of the conduit 16c.

Ce manchon intérieur 25 comporte un fond circulaire 26 muni d'un trou 27 pour le passage de l'axe 22. Un écrou 28 assure le montage du manchon intérieur 25 sur l'axe 22. Des moyens appropriés (non représentés) sont prévus pour que le manchon intérieur 25 soit libre en rotation autour de l'axe 22.This inner sleeve 25 has a circular bottom 26 provided with a hole 27 for the passage of the axis 22. A nut 28 ensures the mounting of the inner sleeve 25 on the axis 22. Appropriate means (not shown) are provided for that the inner sleeve 25 is free to rotate about the axis 22.

Au voisinage de son fond 26, le manchon 25 comporte deux conduits radiaux 30 pourvus chacun à leur extrémité d'un trou 32 pour l'entraînement par réaction du manchon 25 en rotation.In the vicinity of its bottom 26, the sleeve 25 comprises two radial conduits 30 each provided at their end with a hole 32 for the reaction drive of the rotating sleeve 25.

Le manchon intérieur 25 est monté de sorte que les conduits radiaux 30 soient situés entre le fond 26 du manchon intérieur 25 et le fond ajouré 21 du conduit 16c (figure 3).The inner sleeve 25 is mounted so that the radial conduits 30 are located between the bottom 26 of the sleeve interior 25 and the perforated bottom 21 of the conduit 16c (Figure 3).

Le manchon intérieur 25 comporte deux lumières symétriques 34 agencées en sorte de venir en regard, au cours de la rotation du manchon 25, avec les lumières 24 du conduit 16c.The inner sleeve 25 comprises two symmetrical openings 34 arranged so as to come opposite, during the rotation of the sleeve 25, with the openings 24 of the conduit 16c.

Un manchon extérieur 35 enveloppe à distance le manchon intérieur 25 afin de former un déflecteur dont le rôle sera précisé plus loin.An outer sleeve 35 remotely envelops the inner sleeve 25 in order to form a deflector whose role will be explained below.

Le manchon 35 comporte deux échancrures 36 diamétralement opposées recevant les conduits radiaux 30 qui assurent ainsi l'entraînement en rotation dudit manchon 35 (figure 3).The sleeve 35 comprises two diametrically opposite notches 36 receiving the radial conduits 30 which thus ensure the rotational drive of said sleeve 35 (Figure 3).

L'appareil de nettoyage 9 selon l'invention fonctionne de la manière suivante.The cleaning apparatus 9 according to the invention operates in the following manner.

On connecte une extrémité du tuyau souple 10 au conduit 16b. On dispose l'appareil 9 sur le fond de la piscine P et on connecte ensuite l'autre extrémité du tuyau 10 à une bouche de refoulement 5 de la piscine P.One end of the flexible pipe 10 is connected to the conduit 16b. The device 9 is placed on the bottom of the pool P and then the other end of the pipe 10 is connected to a discharge mouth 5 of the pool P.

Sous la pression de l'eau qui s'engage dans le tuyau 10, ce dernier s'étire sensiblement.Under the pressure of the water which engages in the pipe 10, the latter stretches appreciably.

La majeure partie de l'eau refoulée dans le tuyau 10 est expulsée par l'ajutage de la buse 14, le jet sous pression créant une aspiration qui entraîne l'eau du corps 11 dans le réceptacle à débris 17. L'eau aspirée par la bouche 12 entraîne avec elle les débris se trouvant à son voisinage. L'aspiration de l'eau au niveau de l'ouverture 12 a pour effet de créer à la manière connue une dépression sous la collerette 18 et de plaquer l'appareil 9 contre la surface à nettoyer.Most of the water discharged into the pipe 10 is expelled by the nozzle of the nozzle 14, the pressurized jet creating a suction which draws the water from the body 11 into the debris receptacle 17. The water sucked in by the mouth 12 carries with it the debris located in its vicinity. The suction of the water at the opening 12 has the effect of creating, in the known manner, a depression under the flange 18 and of pressing the device 9 against the surface to be cleaned.

Une petite partie de l'eau refoulée dans le tuyau 10 traverse le fond ajouré 21 du conduit 16c, pour être éjectée par les trous 32 des conduits radiaux 30. En réaction, les manchons 25, 35 se mettent à tourner.A small part of the water discharged into the pipe 10 passes through the perforated bottom 21 of the conduit 16c, to be ejected through the holes 32 of the radial conduits 30. In reaction, the sleeves 25, 35 start to rotate.

Au cours de la rotation des manchons 25, 35, les lumières 34 viennent, à chaque demi-tour, coïncider avec les lumières 24 du conduit 16c. Ceci a pour effet de diminuer brusquement et fortement la pression régnant dans le conduit 16 ainsi que dans le tuyau 10, puisque l'eau s'échappe subitement hors du conduit 16 par les lumières 24. Suite à cette brusque diminution de pression, le tuyau 10 se contracte. Lors de cette constriction, le tuyau 10 tire vers lui le conduit 16, ce qui déplace l'appareil. Ce phénomène de déplacement de l'appareil par constriction-étirement répété du tuyau 10 est bien connu et déjà utilisé pour les appareils de nettoyage fonctionnant en aspiration.During the rotation of the sleeves 25, 35, the slots 34 come, at each half-turn, to coincide with the slots 24 of the conduit 16c. This has the effect of abruptly and sharply reducing the pressure prevailing in the duct 16 as well as in the pipe 10, since the water suddenly escapes from the duct 16 through the lights 24. Following this sudden decrease in pressure, the pipe 10 se contracted. During this constriction, the pipe 10 pulls the conduit 16 towards it, which moves the device. This phenomenon of movement of the device by repeated constriction-stretching of the pipe 10 is well known and already used for cleaning devices operating in suction.

Il faut noter que la brusque diminution de pression dans le conduit 16 et le tuyau 10 a pour effet de diminuer la pression du jet de la buse 14 et, par conséquent, de diminuer l'aspiration par la bouche 12. Par suite, la dépression permettant d'obtenir le placage de l'appareil 9 contre la surface à nettoyer est amoindrie, ce qui favorise le déplacement de l'appareil 9.It should be noted that the sudden decrease in pressure in the duct 16 and the pipe 10 has the effect of reducing the pressure of the jet from the nozzle 14 and, consequently, of decreasing the suction by the mouth 12. Consequently, the depression to obtain the plating of the device 9 against the surface to be cleaned is reduced, which promotes the movement of the device 9.

La différence entre le diamètre extérieur du manchon 25 et le diamètre intérieur du manchon 35 est telle que l'eau provenant des lumières 24, 34 puisse être évacuée rapidement entre ces deux manchons, dans une direction qui ne perturbe pas le déplacement de l'appareil 9.The difference between the outside diameter of the sleeve 25 and the inside diameter of the sleeve 35 is such that the water coming from the openings 24, 34 can be quickly evacuated between these two sleeves, in a direction which does not disturb the movement of the device. 9.

La différence entre le diamètre extérieur du conduit 16c et le diamètre intérieur du manchon 25 est telle que les fuites d'eau entre ces deux éléments soient minimes.The difference between the outside diameter of the pipe 16c and the inside diameter of the sleeve 25 is such that the water leaks between these two elements are minimal.

L'éjection d'eau au travers des lumières 24 n'arrête pas la rotation du manchon 25, en sorte que se reproduit ledit phénomène de constriction-étirement du tuyau 10 à chaque coïncidence entre les lumières 24, 34.The ejection of water through the ports 24 does not stop the rotation of the sleeve 25, so that said constriction-stretching phenomenon of the pipe 10 is reproduced at each coincidence between the ports 24, 34.

Il faut remarquer que la dépression créée au voisinage de la bouche d'aspiration 12 et de la collerette 18 permet à l'appareil d'être plaqué aussi bien au fond de la piscine que sur ses parois, même sensiblement verticales.It should be noted that the depression created in the vicinity of the suction mouth 12 and the flange 18 allows the device to be pressed as well at the bottom of the pool as on its walls, even substantially vertical.

L'appareil décrit est peu coûteux et s'adapte à tous les types de piscines. Il limite les perturbations dans le fonctionnement des skimmers 2 et de la bonde de fond 1, qui continuent à assurer leur fonction pendant l'utilisation de l'appareil.The apparatus described is inexpensive and adapts to all types of swimming pools. It limits the disturbances in the functioning of the skimmers 2 and of the bottom drain 1, which continue to ensure their function during the use of the device.

Comme l'appareil 9 fonctionne en refoulement, les àcoups provoqués ne sont pas dommageables à la pompe 3.As the device 9 operates in discharge, the jolts caused are not harmful to the pump 3.

Il n'est absolument pas nécessaire d'amorcer le fonctionnement de l'appareil 9, et encore moins de le surveiller pendant son fonctionnement.There is absolutely no need to initiate the operation of the device 9, and even less to monitor it during its operation.

Le réceptacle à débris 17 permet de ne pas encrasser davantage les pré-filtres et filtres 4 du circuit d'aspiration de la piscine, diminuant au passage les risques de cavitation de la pompe 3.The debris receptacle 17 makes it possible not to further foul the pre-filters and filters 4 of the circuit of the pool, reducing the risk of cavitation of the pump 3.

L'appareil 9 décrit ci-dessus accepte de nombreuses variantes, parmi lesquelles celles des figures 6 à 11.The device 9 described above accepts many variants, including those of FIGS. 6 to 11.

Sur la figure 6, on a illustré une variante dans laquelle le réceptacle à débris 17 est remplacé par une cartouche filtrante amovible à paroi opaque 37. Cette cartouche 37 rend l'appareil plus esthétique, puisque les débris restent cachés à l'intérieur de la cartouche.In FIG. 6, a variant has been illustrated in which the debris receptacle 17 is replaced by a removable filter cartridge with an opaque wall 37. This cartridge 37 makes the device more aesthetic, since the debris remains hidden inside the cartridge.

Sur la figure 7, on a muni le conduit 16b d'un manchon externe 38 entraîné en rotation au moyen d'une turbine 39 alimentée par une partie de l'eau circulant dans le conduit 16b. Cette turbine entraîne le manchon 38 par un système à pignon 40 et courroie 41. Un réducteur de vitesse, représenté symboliquement en 50, est disposé entre la turbine 39 et le pignon 40.In FIG. 7, the pipe 16b has been provided with an external sleeve 38 driven in rotation by means of a turbine 39 supplied with part of the water circulating in the pipe 16b. This turbine drives the sleeve 38 by a pinion 40 and belt 41 system. A speed reducer, symbolically represented at 50, is disposed between the turbine 39 and the pinion 40.

Le manchon 38 comporte un conduit d'échappement 43 d'axe perpendiculaire à l'axe I et un conduit d'échappement 44 coudé en direction de l'appareil 9.The sleeve 38 comprises an exhaust duct 43 with an axis perpendicular to the axis I and an exhaust duct 44 bent in the direction of the device 9.

La rotation du manchon 38 autour du conduit 16b permet aux conduits d'échappement 43 et 44 de communiquer alternativement avec ledit conduit 16b via un orifice 45.The rotation of the sleeve 38 around the duct 16b allows the exhaust ducts 43 and 44 to communicate alternately with said duct 16b via an orifice 45.

Le rôle des conduits d'échappement 43, 44 est d'engendrer un déport latéral du conduit 16b avec une composante parallèle à l'axe I dont les effets s'ajoutent à ceux de la constriction et de l'étirement du tuyau 10.The role of the exhaust pipes 43, 44 is to generate a lateral offset of the pipe 16b with a component parallel to the axis I, the effects of which add to those of the constriction and the stretching of the pipe 10.

Le dispositif décrit en regard de la figure 7 peut remplacer ou compléter la vanne de décharge 19.The device described with reference to FIG. 7 can replace or supplement the relief valve 19.

La figure 8 représente schématiquement une variante de l'appareil de l'invention, dans laquelle la partie coudée du conduit 16 est articulée en 46, autour d'un axe sensiblement perpendiculaire au plan défini par l'axe du corps 11 et l'axe H du conduit 16a. Ceci permet de faciliter le passage de l'appareil 9 du fond aux parois de la piscine.FIG. 8 schematically represents a variant of the apparatus of the invention, in which the bent part of the conduit 16 is articulated at 46, around an axis substantially perpendicular to the plane defined by the axis of the body 11 and the axis H of conduit 16a. This facilitates the passage of the device 9 from the bottom to the walls of the pool.

La figure 9 représente schématiquement une partie d'une quatrième variante de l'appareil de l'invention, dans laquelle la vanne de décharge cyclique est prévue, non pas sur un prolongement du conduit 16a hors du corps 11 ou sur le conduit 16b, mais sur une pièce de connexion du tuyau 10 à la bouche de refoulement 5. La pièce de connexion, similaire au dispositif représenté sur la figure 7, est symbolisée en 47.FIG. 9 schematically represents part of a fourth variant of the apparatus of the invention, in which the cyclic discharge valve is provided, not on an extension of the pipe 16a outside the body 11 or on the pipe 16b, but on a connection piece from the pipe 10 to the discharge mouth 5. The connection piece, similar to the device shown in FIG. 7, is symbolized at 47.

On peut éventuellement supprimer la partie inclinée 16b du conduit 16 et connecter directement le tuyau 10 à la partie 16a.Optionally, the inclined portion 16b of the conduit 16 can be removed and the pipe 10 directly connected to the portion 16a.

Enfin, les figures 10 et 11 illustrent un perfectionnement de l'appareil de l'invention destiné à le décoller de la paroi de la piscine lorsqu'il arrive sur la ligne d'eau. A cet effet, l'appareil est muni d'un tube souple 48 débouchant dans le corps 11, de préférence en dessous du diffuseur à venturi et pourvu à son extrémité libre d'un flotteur 49.Finally, Figures 10 and 11 illustrate an improvement of the apparatus of the invention intended to peel it from the wall of the swimming pool when it arrives on the water line. To this end, the apparatus is provided with a flexible tube 48 opening into the body 11, preferably below the venturi diffuser and provided at its free end with a float 49.

Lorsque l'appareil arrive à la ligne d'eau (figure 11), le tube 48 fait pénétrer temporairement de l'air dans le corps 11 et le filtre 37, ce qui fait basculer l'appareil suivant la flèche 50.When the apparatus arrives at the water line (FIG. 11), the tube 48 temporarily introduces air into the body 11 and the filter 37, which causes the apparatus to tilt according to arrow 50.

L'appareil se redresse en se décollant ainsi automatiquement de la paroi verticale 51 de la piscine, puis plonge vers le fond tout en se purgeant de l'air qui a été introduit par le tube 48.The apparatus straightens up, thus peeling off automatically from the vertical wall 51 of the swimming pool, then plunges towards the bottom while purging the air which has been introduced by the tube 48.

Un tel dispositif améliore l'efficacité de l'appareil en réduisant le temps passé sur les parois de la piscine.Such a device improves the efficiency of the device by reducing the time spent on the walls of the pool.

Bien entendu, l'invention n'est pas limitée aux modes de réalisation représentés et décrits, mais en couvre au contraire toutes les variantes, notamment en ce qui concerne la structure et l'emplacement en un endroit quelconque entre la buse 14 et la bouche de refoulement 5 de la vanne de décharge 19. Il est à noter que la bouche de refoulement peut être remplacée par d'autres dispositifs fournissant de l'eau sous pression, tels qu'un surpresseur.Of course, the invention is not limited to the embodiments shown and described, but on the contrary covers all variants thereof, in particular with regard to the structure and the location at any location between the nozzle 14 and the mouth. discharge 5 of the discharge valve 19. It should be noted that the discharge mouth can be replaced by other devices supplying water under pressure, such as a booster.
