Description

DISPOSITIF DE BRANCHEMENT D'UNE TETE DE NETTOYAGE DEVICE FOR CONNECTING A CLEANING HEAD
PAR ASPIRATION DU FOND D'UNE PISCINEBY SUCTION FROM THE BOTTOM OF A POOL
A UNE BOUCHE DE REFOULEMENT DE CETTE DERNIERETO A DISCHARGE OF THIS LAST
La présente invention a trait au nettoyage des fonds de piscine à l'aide de têtes de nettoyage, telles qu'un balai ou un appareil automatique dénommé robot, fonctionnant par aspiration d'eau. Dans ce type de nettoyeur, la tête de nettoyage est reliée par une canalisation souple à un circuit d'aspiration d'eau créant entre la tête et la paroi de la piscine (fond ou parois latérales) une dépression aspirant les particules et débris à évacuer qui sont entraînés à travers la tête, puis la canalisation, vers un circuit de recyclage de l'eau après filtration des particules et débris divers.The present invention relates to the cleaning of swimming pool bottoms using cleaning heads, such as a broom or an automatic device called a robot, operating by suction of water. In this type of cleaner, the cleaning head is connected by a flexible pipe to a water suction circuit creating between the head and the wall of the pool (bottom or side walls) a vacuum aspirating the particles and debris to be evacuated which are driven through the head, then the pipe, to a water recycling circuit after filtration of particles and various debris.
Le circuit d'aspiration d'eau de tels appareils de nettoyage est en fait constitué par le circuit d'aspiration de la piscine. Le branchement sur le circuit d'aspiration de la piscine du tuyau flottant à l'extrémité duquel est connecté le balai ou le robot, présente plusieurs inconvénients.The water suction circuit of such cleaning devices is in fact constituted by the pool suction circuit. The connection to the suction circuit of the swimming pool of the floating pipe at the end of which is connected the broom or the robot, has several disadvantages.
Il est difficile d'amorcer la circulation d'eau dans le système du fait de la présence d'air dans le tuyau flottant qui désamorce la pompe du circuit de recyclage dans la piscine de l'eau aspirée par le dispositif d'aspiration.It is difficult to initiate the circulation of water in the system due to the presence of air in the floating pipe which deactivates the pump of the recycling circuit in the pool of water sucked by the suction device.
Par ailleurs, il s'opère un entraînement de dépôts (sable, gravier, cheveux, insectes,...) vers la pompe et de feuilles vers les paniers de récupération de l'écumeur ou vers le pré-filtre de la pompe. Or, ces paniers ont une capacité limitée et doivent parfois être vidés en cours de nettoyage pour rétablir une aspiration suffisante.In addition, there is a entrainment of deposits (sand, gravel, hair, insects, ...) to the pump and leaves to the skimmer recovery baskets or to the pump pre-filter. However, these baskets have a limited capacity and must sometimes be emptied during cleaning to restore sufficient suction.
De plus, il est nécessaire de laver le filtre principal encrassé à la fin de l'opération, ce qui entraîne une perte d'eau.In addition, it is necessary to wash the dirty main filter at the end of the operation, which results in loss of water.
Certains appareils automatiques provoquent des à-coups dûs a la fermeture brutale du circuit d'aspiration, pouvant intervenir plusieurs fois par minute et endommager la pompe. En fonctionnement continu, par exemple en cas d'absence prolongée de l'utilisateur de la piscine, les appareils automatiques risquent de colmater des pré-filtres ou le filtre principal, entraînant un risque de cavitation et de détérioration de la pompe. Enfin, ces appareils automatiques réduisent et même parfois, selon la puissance de la pompe, suppriment l'aspiration en surface qui est destinée à balayer le plan d'eau de la piscine pour évacuer la pollution de surface.Some automatic devices cause jolts due to the sudden closing of the suction circuit, which can occur several times a minute and damage the pump. In continuous operation, for example in the event of prolonged absence of the user of the swimming pool, automatic devices risk clogging the pre-filters or the main filter, causing a risk of cavitation and damage to the pump. Finally, these automatic devices reduce and sometimes even, depending on the power of the pump, remove the suction on the surface which is intended to sweep the water level of the swimming pool to remove surface pollution.
Par le document US-A-5 238 585, on connaît un dispositif de branchement d'une tête de nettoyage par aspiration du fond d'une baignoire à bulles ou spa, à une bouche de refoulement de cette dernière, comprenant une buse d'éjection d'eau munie, côté amont, de moyens de raccordement rapide sur ladite bouche de refoulement et reliée de manière amovible à un tuyau souple de raccordement à ladite tête de nettoyage et un réceptacle des particules et débris divers aspirés. Cependant, ledit tuyau souple est simplement branché à 90° sur le flux de sortie de la bouche de refoulement et à la sortie de la buse, si bien que l'effet d'aspiration est peu efficace. Il faut d'ailleurs noter que ce dispositif est spécialement et uniquement destiné à des spas, c'est-à-dire à des systèmes de dimensions réduites et non à des piscines, justement à cause de leur puissance et performances réduites. Un tel dispositif serait en particulier incapable d'être branché sur un appareil de nettoyage automatique du type robot.Document US-A-5 238 585 discloses a device for connecting a cleaning head by suction from the bottom of a bubble bath or spa, to a discharge mouth of the latter, comprising a nozzle. water ejection provided, on the upstream side, with rapid connection means on said discharge mouth and connected in a removable manner to a flexible pipe for connection to said cleaning head and a receptacle for particles and various debris sucked up. However, said flexible hose is simply connected at 90 ° to the outlet flow from the discharge mouth and to the outlet of the nozzle, so that the suction effect is not very effective. It should also be noted that this device is specially and only intended for spas, that is to say systems of reduced dimensions and not for swimming pools, precisely because of their reduced power and performance. Such a device would in particular be incapable of being connected to an automatic cleaning device of the robot type.
La présente invention vise à remédier à ces divers inconvénients en proposant un dispositif de branchement de la tête de nettoyage des appareils évoqués ci-dessus, permettant une récupération beaucoup plus efficace des dépôts et débris divers .The present invention aims to remedy these various drawbacks by proposing a device for connecting the cleaning head of the devices mentioned above, allowing a much more efficient recovery of deposits and debris. various.
A cet effet, l'invention a pour objet un dispositif de branchement d'une tête de nettoyage par aspiration du fond d'une piscine, à une bouche de refoulement de cette dernière, comprenant une buse d'éjection d'eau munie, côté amont, de moyens de raccordement rapide sur ladite bouche de refoulement et reliée de manière amovible à un tuyau souple de raccordement à ladite tête de nettoyage et un réceptacle des particules et débris divers aspirés, caractérisé en ce que ledit tuyau souple est relié à ladite buse par un conduit enveloppant la partie aval de la buse et définissant immédiatement en aval de l'ajutage de la buse un diffuseur de type venturi coaxial au flux d'eau éjecté par la buse, ledit réceptacle étant monté à l'extrémité aval dudit diffuseur. Suivant un mode préféré de réalisation, ladite buse comprend un conduit disposable dans l'axe de la bouche de refoulement et une partie aval formée par un conduit en forme de convergent, d'éjection latérale du flux d'eau sous forme générale d'un pinceau dont l'axe est sensiblement confondu avec l'axe dudit diffuseur, l'ajutage dudit conduit d'éjection se trouvant légèrement en amont du col du diffuseur.To this end, the invention relates to a device for connecting a cleaning head by suction from the bottom of a swimming pool, to a discharge mouth of the latter, comprising a water ejection nozzle provided, on the side upstream, quick connection means on said delivery mouth and removably connected to a flexible pipe connecting to said cleaning head and a receptacle for particles and various debris sucked in, characterized in that said flexible pipe is connected to said nozzle by a duct enveloping the downstream part of the nozzle and defining immediately downstream of the nozzle nozzle a venturi type diffuser coaxial with the flow of water ejected by the nozzle, said receptacle being mounted at the downstream end of said diffuser. According to a preferred embodiment, said nozzle comprises a conduit arranged in the axis of the discharge mouth and a downstream part formed by a conduit in the form of a convergent, for lateral ejection of the water flow in the general form of a brush whose axis is substantially coincident with the axis of said diffuser, the nozzle of said ejection duct being located slightly upstream of the neck of the diffuser.
Suivant une variante, ladite buse comprend un conduit disposable dans l'axe de la bouche de refoulement et un ajutage constitué d'un alignement de trous calibrés réalisés directement dans la paroi dudit conduit suivant une génératrice de ce dernier.According to a variant, said nozzle comprises a conduit arranged in the axis of the discharge mouth and a nozzle consisting of an alignment of calibrated holes made directly in the wall of said conduit according to a generator of the latter.
Le réceptacle des particules et débris divers est par exemple un sac ou filet amovible ou autre structure ajourée amovible, dimensionnée en sorte de retenir des éléments supérieurs à une taille déterminée.The receptacle for particles and various debris is for example a removable bag or net or other removable perforated structure, dimensioned so as to retain elements larger than a determined size.
Avantageusement, le conduit de la buse d'éjection est muni, extérieurement au diffuseur, d'un clapet de décharge susceptible d'évacuer un débit excédentaire. Au lieu d'un clapet, on peut également prévoir une vanne à fonctionnement cyclique minuté orientant le flux d'eau, soit vers le diffuseur à venturi, soit directement vers la piscine. Un tel dispositif est remarquablement efficace. En effet, en comparaison avec le dispositif de US-A-5 238 585, l'effet d'aspiration sur le fluide circulant dans ledit tuyau souple est bien plus efficace, grâce à l'agencement particulier de la jonction entre ce tuyau et la buse et à la prévision d'un diffuseur de type venturi immédiatement en aval de l'ajutage de ladite buse. D'autres caractéristiques et avantages ressortiront de la description qui va suivre de modes de réalisation du dispositif de l'invention, description donnée à titre d'exemple uniquement et en regard des dessins annexés sur lesquels : - Figure 1 est une vue schématique en élévation et en coupe d'une piscine équipée d'un balai de nettoyage à branchement conventionnel ;Advantageously, the duct of the ejection nozzle is provided, outside the diffuser, with a relief valve capable of discharging an excess flow. Instead of a valve, it is also possible to provide a timed cyclic operation valve directing the water flow, either towards the venturi diffuser, or directly towards the swimming pool. Such a device is remarkably effective. Indeed, in comparison with the device of US-A-5 238 585, the suction effect on the fluid circulating in said flexible hose is much more efficient, thanks to the particular arrangement of the junction between this hose and the nozzle and to the provision of a venturi-type diffuser immediately downstream of the nozzle of said nozzle. Other characteristics and advantages will emerge from the description which follows of embodiments of the device of the invention, description given by way of example only and with reference to the appended drawings in which: - Figure 1 is a schematic elevation view and in section of a swimming pool equipped with a cleaning brush with conventional connection;

5, illustrant une variante de réalisation de la buse d'éjection du dispositif.5, illustrating an alternative embodiment of the device ejection nozzle.
Sur les figures 1 et 2 on a représenté schématiquement en 1 un bassin de piscine, en 2 une pompe de recyclage de l'eau vers la piscine, en 3 un filtre principal interposé entre la pompe 2 et une bouche 4 de refoulement de l'eau dans le bassin 1 et en 5 un dispositif conventionnel de récupération de l'eau de surface par aspiration, relié à la pompe 2.In FIGS. 1 and 2 there is shown schematically at 1 a swimming pool, at 2 a pump for recycling water to the swimming pool, at 3 a main filter interposed between the pump 2 and a mouth 4 for discharging the water in basin 1 and in 5 a conventional device for recovering surface water by suction, connected to pump 2.
Le dispositif 5 est muni d'un système de filtration pour éviter aux débris divers de surface (feuilles, insectes, etc ..) de passer dans le circuit de la pompe 2.The device 5 is provided with a filtration system to prevent various surface debris (leaves, insects, etc.) from passing through the circuit of the pump 2.
Sur le fond de la piscine repose un balai 6 de nettoyage par aspiration, relié par un tuyau souple flottant 7 à un embout approprié dudit dispositif de récupération 5 permettant de créer dans le tuyau 7 l'aspiration nécessaire à l'entraînement des déchets à évacuer, ceux-ci étant retenus et stockés dans le système de filtration dont est muni le dispositif 5.On the bottom of the swimming pool rests a suction cleaning brush 6, connected by a flexible floating pipe 7 to an appropriate nozzle of said recovery device 5 making it possible to create in the pipe 7 the suction necessary for entraining the waste to be evacuated , these being retained and stored in the filtration system with which the device 5 is fitted.
La figure 2 illustre la même piscine 1 équipée du dispositif selon l'invention, désigné d'une manière générale par la référence numérique 8 et branché, d'une part, à l'extrémité du tuyau 7 et, d'autre part, sur la bouche de refoulement 4.FIG. 2 illustrates the same swimming pool 1 equipped with the device according to the invention, generally designated by the reference numeral 8 and connected, on the one hand, to the end of the pipe 7 and, on the other hand, to the discharge opening 4.
Les figures 3 à 5 représentent un mode de réalisation du dispositif 8 selon l'invention. .Ce dispositif comprend une buse d'éjection d'eau 9 constituée d'un conduit 9a cylindrique, disposé dans l'axe de la bouche de refoulement 4 et muni, à cet effet, de moyens d'assemblage rapide, par une extrémité mâle filetée 10 susceptible de s'engager dans un raccord fileté femelle 11 scellé dans la paroi du bassin de piscine 1 et constituant la bouche de refoulement 4.Figures 3 to 5 show an embodiment of the device 8 according to the invention. .This device comprises a water ejection nozzle 9 consisting of a cylindrical conduit 9a, disposed in the axis of the discharge mouth 4 and provided, for this purpose, with rapid assembly means, by a male end threaded 10 capable of engaging in a female threaded connection 11 sealed in the wall of the swimming pool basin 1 and constituting the discharge mouth 4.
Le conduit 9a est prolongé latéralement par un conduit d'éjection 9b définissant un ajutage de section rectangulaire aplati. La section du conduit 9b va en se rétrécissant progressivement depuis le conduit 9a jusqu'à l'ajutageThe conduit 9a is extended laterally by an ejection conduit 9b defining a nozzle of flattened rectangular section. The section of the conduit 9b tapers progressively from the conduit 9a to the nozzle
(figure 5) en forme de fente étroite générant un jet d'eau en lame ou pinceau dont l'axe général est sensiblement perpendiculaire à l'axe du conduit 9a.(Figure 5) in the form of a narrow slot generating a jet of water in the form of a blade or brush, the general axis of which is substantially perpendicular to the axis of the conduit 9a.
La majeure partie de la buse 9 s'étend à l'intérieur d'un diffuseur 12 du type à venturi, comprenant une partie cylindrique 12a disposée sensiblement perpendiculairement à l'axe du conduit 9a et coaxialement au flux d'eau éjecté par le conduit 9b. Les parois du conduit 12a sont à distance suffisante du conduit 9a de façon que la section de passage dans cette zone corresponde sensiblement à la section interne du tuyau 7 qui est relié de manière amovible à l'extrémité amont du diffuseur 12. Le tuyau 7 comporte par exemple un embout 13 emboîtable à force dans l'extrémité du conduit 12a.The major part of the nozzle 9 extends inside a diffuser 12 of the venturi type, comprising a cylindrical part 12a disposed substantially perpendicular to the axis of the conduit 9a and coaxially with the flow of water ejected through the conduit 9b. The walls of the duct 12a are at a sufficient distance from the duct 9a so that the passage section in this zone corresponds substantially to the internal section of the pipe 7 which is removably connected to the upstream end of the diffuser 12. The pipe 7 comprises for example a nozzle 13 which can be force-fitted into the end of the conduit 12a.
Le conduit 12a est prolongé, au droit du conduit 9b, par un venturi 12b dont le col 14 se situe à quelques millimètres en aval de l'ajutage du conduit 9b.The conduit 12a is extended, in line with the conduit 9b, by a venturi 12b whose neck 14 is located a few millimeters downstream of the nozzle of the conduit 9b.
Le col 14 (figure 5) présente une section aplatie similaire à la section de sortie du conduit 9b.The neck 14 (Figure 5) has a flattened section similar to the outlet section of the conduit 9b.
A l'extrémité du venturi 12b est fixé de manière amovible un réceptacle 15 à déchets à structure ajourée permettant le libre passage de l'eau expulsée par l'éjecteur 9.At the end of the venturi 12b is removably attached a receptacle 15 for waste with openwork structure allowing the free passage of the water expelled by the ejector 9.
Le réceptacle 15 est par exemple un sac ou filet à mailles qui peut être retiré a des fins de nettoyage. Sur la figure 3 on a représenté par ailleurs en 16 un clapet de décharge monté dans l'extrémité du conduit 9a opposée à la bouche 4 et faisant saillie en dehors du diffuseur 12.The receptacle 15 is for example a bag or mesh net which can be removed for cleaning purposes. FIG. 3 also shows at 16 a relief valve mounted in the end of the conduit 9a opposite the mouth 4 and projecting outside the diffuser 12.
Le rôle du clapet 16 est d'évacuer automatiquement l'éventuel débit d'eau excédentaire délivré par la bouche 4, lequel est fonction de la puissance de la pompe 2.The role of the valve 16 is to automatically evacuate any excess water flow delivered by the mouth 4, which is a function of the power of the pump 2.
Le clapet 16 peut être remplacé par une vanne à commande cyclique par minutage permettant d'orienter le débit de refoulement de la bouche 4, soit vers l'ajutage du conduit 9b, soit vers le bassin de la piscine 1.The valve 16 can be replaced by a valve with cyclic control by timing allowing the discharge flow rate from the mouth 4 to be oriented, either towards the nozzle of the conduit 9b, or towards the pool of the swimming pool 1.
Le jet sous pression formé par le conduit 9b et dirigé vers le col 14 et le divergent du venturi crée une forte aspiration entraînant l'eau du tuyau 7 vers le divergent du diffuseur 12 avec un débit suffisant pour faire fonctionner le balai 6 et aspirer efficacement les déchets qui seront retenus prisonniers du réceptacle 15.The pressurized jet formed by the conduit 9b and directed towards the neck 14 and the divergent part of the venturi creates a strong suction drawing the water from the pipe 7 towards the divergent part of the diffuser 12 with a sufficient flow rate to operate the brush 6 and suck effectively the waste which will be kept prisoners of the receptacle 15.
La forme rectangulaire aplatie du conduit 9b et du venturi 14 permet d'améliorer le rendement hydraulique en augmentant (à débit de la pompe 2 constant) la surface de contact entre le jet moteur engendré par le conduit 9b et le liquide aspiré provenant du tuyau 7 et traversant le diffuseur 12.The flattened rectangular shape of the pipe 9b and the venturi 14 improves the hydraulic efficiency by increasing (at constant pump flow 2) the contact surface between the motor jet generated by the pipe 9b and the liquid sucked from the pipe 7 and passing through the diffuser 12.
L'eau sortant du réceptacle est débarrassée de ses déchets et alimente le bassin dont le trop-plein est repris par le système conventionnel 5, lequel traite ainsi une eau déjà substantiellement dépolluée.The water leaving the receptacle is rid of its waste and feeds the basin, the overflow of which is taken up by the conventional system 5, which thus treats water which is already substantially decontaminated.
Le balai 6 fonctionne de la même manière et est tout aussi efficace, qu'il soit raccordé au dispositif d'aspiration 5 ou au dispositif 8 de l'invention. La figure 6 illustre une variante de réalisation de l'ajutage de l'éjecteur 9, selon laquelle le conduit 9b à convergent et section de sortie rectangulaire est remplacé par un ajutage constitué par un alignement de trous calibrésThe brush 6 works in the same way and is just as effective, whether it is connected to the suction device 5 or to the device 8 of the invention. FIG. 6 illustrates an alternative embodiment of the nozzle of the ejector 9, according to which the duct 9b with converging and rectangular outlet section is replaced by a nozzle constituted by an alignment of calibrated holes
17 réalisés directement dans la paroi du conduit cylindrique 9a suivant une génératrice de ce dernier. Dans le mode de réalisation représenté sur les dessins, le diffuseur 12 est dirigé vers le fond de la piscine, mais il pourrait avoir une autre orientation, de même que le conduit 9a vis à vis de la paroi de la piscine, dans la mesure où l'axe du diffuseur venturi 12 et l'axe du flux d'eau de sortie de l'éjecteur sont sensiblement confondus.17 produced directly in the wall of the cylindrical conduit 9a along a generator of the latter. In the embodiment shown in the drawings, the diffuser 12 is directed towards the bottom of the swimming pool, but it could have another orientation, as does the conduit 9a with respect to the wall of the swimming pool, insofar as the axis of the venturi diffuser 12 and the axis of the water flow leaving the ejector are substantially combined.
C'est ainsi que l'éjecteur 9 pourrait être agencé coaxiale ent à l'axe de refoulement de la bouche 4, le diffuseur 12 faisant un coude en partie amont pour être raccordé au tuyau 7.Thus the ejector 9 could be arranged coaxial with the delivery axis of the mouth 4, the diffuser 12 making a bend in the upstream part to be connected to the pipe 7.
De même, les formes et dimensions tant de l'ensemble éjecteur 9 que de l'ensemble diffuseur 12 peuvent varier sans sortir pour autant du cadre de l'invention.Likewise, the shapes and dimensions of both the ejector assembly 9 and the diffuser assembly 12 can vary without departing from the scope of the invention.
L'utilisation du dispositif de l'invention ne nuit en rien au fonctionnement et à l'efficacité du circuit traditionnel d'aspiration des eaux de surfaces et de recyclage par la bouche de refoulement 4 via l'ensemble pompe 2 - filtre 3. The use of the device of the invention in no way detracts from the operation and the efficiency of the traditional circuit for sucking in surface water and recycling through the discharge mouth 4 via the pump 2 - filter 3 assembly.
