Abstract
Description
La présente invention concerne une bouche d'aspiration pour une pompe aspirant du liquide en surface, notamment de l'eau d'une piscine. The present invention relates to a suction mouth for a pump sucking liquid on the surface, in particular water from a swimming pool.
La circulation de l'eau d'une piscine est assurée par une pompe. L'eau est alors aspirée dans le bassin par une bonde de fond ainsi qu'à travers au moins un écumeur de surface comprenant la pompe qui débouche directement dans le bassin sous la forme d'une bouche évasée, qui est couramment appelée meurtrière. Un écumeur a pour fonction d'aspirer les impuretés se trouvant à la surface de l'eau et de les retenir dans un filtre, appelé panier. The circulation of water in a swimming pool is ensured by a pump. The water is then sucked into the basin by a bottom drain as well as through at least one surface skimmer comprising the pump which opens directly into the basin in the form of a flared mouth, which is commonly called deadly. A skimmer has the function of sucking up the impurities on the surface of the water and retaining them in a filter, called a basket.
La meurtrière a pour but d'augmenter l'angle d'ouverture au niveau de la surface de l'eau afin d'améliorer le pouvoir d'aspiration de la pompe et de l'écumeur de surface. The purpose of the loophole is to increase the opening angle at the water surface to improve the suction power of the pump and the surface skimmer.
Une meurtrière connue présente des surfaces planes se dirigeant vers l'entrée de l'écumeur de surface. De face, elle est de forme rectangulaire et vue de dessus, elle présente un profil trapézoïdal. A known loophole has flat surfaces pointing towards the entrance to the surface skimmer. From the front, it is rectangular in shape and seen from above, it has a trapezoidal profile.
Pour assurer l'étanchéité de la piscine au niveau de la meurtrière, des joints maintenus à l'aide d'une bride sont fixés sur le pourtour de la meurtrière, entre cette dernière et le revêtement de la piscine. Afin de cacher la bride et les vis nécessaires à sa fixation, un enjoliveur en forme de cadre rectangulaire peut recouvrir ces éléments. Cet enjoliveur est en saillie dans la piscine par rapport au revêtement de celle-ci. To ensure the watertightness of the pool at the level of the loophole, joints maintained with the help of a flange are fixed on the periphery of the loophole, between the latter and the covering of the swimming pool. In order to hide the flange and the screws necessary for its fixing, a cover in the form of a rectangular frame can cover these elements. This cover protrudes into the pool relative to the coating thereof.
Cette meurtrière ne permet pas une bonne circulation de l'eau. En effet, l'eau n'est pas aspirée sur les bords de la piscine à proximité immédiate de la meurtrière à cause de l'enjoliveur mais aussi à cause de la forme de la meurtrière. Or c'est à cet endroit de la piscine qu'ont tendance à se rassembler les saletés. Ces dernières ne sont donc pas aspirées par l'écumeur de surface et restent donc dans la piscine. This loophole does not allow good circulation of water. Indeed, water is not sucked on the edges of the swimming pool in the immediate vicinity of the loophole because of the hubcap but also because of the shape of the loophole. It is at this point in the pool that dirt tends to collect. The latter are therefore not sucked in by the surface skimmer and therefore remain in the pool.
De plus les différents angles intérieurs de la meurtrière constituent des recoins difficiles à nettoyer et dans lesquels la saleté s'accumule. In addition, the different interior angles of the loophole constitute corners difficult to clean and in which dirt accumulates.
Le but de l'invention est donc de fournir une meurtrière permettant d'obtenir une aspiration latérale, et dans laquelle la saleté ne peut pas s'accumuler, et qui soit enfin d'une esthétique agréable. The object of the invention is therefore to provide a loophole making it possible to obtain a lateral suction, and in which the dirt cannot accumulate, and which is finally of a pleasant aesthetic.
A cet effet, elle propose une bouche d'aspiration pour une pompe aspirant du liquide, notamment de l'eau d'une piscine, destinée à être placée au niveau de la surface du liquide, caractérisée en ce que sa face d'entrée du liquide a une forme sensiblement ovale et en ce que ses sections parallèles à la surface du liquide présentent chacune la forme de deux courbes, dont les faces convexes sont en regard. To this end, it offers a suction mouth for a pump sucking liquid, in particular water from a swimming pool, intended to be placed at the level of the surface of the liquid, characterized in that its inlet face of the liquid has a substantially oval shape and in that its sections parallel to the surface of the liquid each have the form of two curves, the convex faces of which are opposite.
Cette nouvelle forme permet un meilleur écoulement du liquide vers la pompe et permet notamment d'aspirer l'eau se trouvant près des bords de la bouche d'aspiration. De plus, cette dernière ne présente plus de recoins dans lesquels la saleté peut s'accumuler. This new shape allows better flow of the liquid towards the pump and in particular makes it possible to suck up the water located near the edges of the suction mouth. In addition, the latter no longer has nooks in which dirt can accumulate.
L'invention propose plusieurs formes de la face d'entrée de la bouche d'aspiration. Selon une première forme d'exécution, cette face d'entrée a une forme composée de deux demi-cercles reliés par des segments de droite sensiblement parallèles à la surface de l'eau, et selon une seconde forme d'exécution, elle a une forme d'ellipse dont le grand axe est parallèle à la surface de l'eau. The invention proposes several forms of the entry face of the suction mouth. According to a first embodiment, this entry face has a shape composed of two semicircles connected by straight segments substantially parallel to the surface of the water, and according to a second embodiment, it has a form of ellipse whose major axis is parallel to the surface of the water.
En ce qui concerne les sections parallèles à la surface du liquide de la bouche d'aspiration, elles présentent de préférence la forme d'une section d'hyperbole. As regards the sections parallel to the surface of the liquid of the suction mouth, they preferably have the shape of a hyperbola section.
Le bord de la bouche d'aspiration est fixé de manière étanche au bord du réservoir contenant le liquide, notamment une piscine. Cette fixation présente en général des joints et une bride qui sont cachés par un enjoliveur.
L'invention propose également un tel enjoliveur, adapté à une bouche d'aspiration telle que décrite ci-dessus. Cet enjoliveur, destiné à recouvrir le bord périphérique de la face d'entrée de la bouche d'aspiration, est caractérisé en ce que sa forme est dans la continuité de la forme de la bouche d'aspiration.The edge of the suction mouth is tightly fixed to the edge of the tank containing the liquid, in particular a swimming pool. This attachment generally has gaskets and a flange which are hidden by a cover.
The invention also provides such a hubcap, suitable for a suction mouth as described above. This cover, intended to cover the peripheral edge of the inlet face of the suction mouth, is characterized in that its shape is in continuity with the shape of the suction mouth.
Un tel enjoliveur peut par exemple présenter une section sensiblement semi-circulaire se raccordant à la forme de la bouche d'aspiration. Such a hubcap may for example have a substantially semi-circular section connecting to the shape of the suction mouth.
De toute façon, l'invention sera bien comprise à l'aide de la description qui suit, en référence au dessin schématique annexé, représentant à titre d'exemple non limitatif une bouche d'aspiration et un enjoliveur selon l'invention
Figure 1 est une vue en perspective d'un ensemble bouche d'aspiration, meurtrière montée sur la paroi d'une piscine ;
Figure 2 est une vue de face de cet ensemble ; et
Figure 3 est une vue en coupe selon la ligne III
III de la figure 2.In any case, the invention will be clearly understood with the aid of the description which follows, with reference to the appended schematic drawing, representing by way of nonlimiting example a suction mouth and a hubcap according to the invention
Figure 1 is a perspective view of a suction mouth assembly, deadly mounted on the wall of a swimming pool;
Figure 2 is a front view of this assembly; and
Figure 3 is a sectional view along line III
III of Figure 2.
Les figures représentent une bouche d'aspiration 1 pour un écumeur de surface aspirant l'eau d'une piscine. The figures represent a suction mouth 1 for a surface skimmer sucking water from a swimming pool.
Cette bouche d'aspiration, ou meurtrière 1, est montée dans une paroi 2 de la piscine et est immergée à environ un peu plus de la moitié de sa hauteur. Elle est fixée d'une part à la paroi 2 de la piscine et d'autre part à un écumeur de surface 3. Une pompe (non représentée) assure la circulation de l'eau de la piscine à travers l'écumeur de surface 3 sur lequel est montée la meurtrière 1. Un enjoliveur 4 est fixé sur le pourtour de la meurtrière se trouvant du côté de la piscine.This suction mouth, or loophole 1, is mounted in a wall 2 of the swimming pool and is immersed at a little more than half of its height. It is fixed on the one hand to the wall 2 of the swimming pool and on the other hand to a surface skimmer 3. A pump (not shown) ensures the circulation of the water in the swimming pool through the surface skimmer 3 on which is mounted the loophole 1. A trim 4 is fixed on the periphery of the loophole located on the side of the swimming pool.
Vu de face (figure 2), c'est-à-dire vu depuis la piscine, la face d'entrée de la meurtrière présente la forme de deux demi-cercles 5 reliés par deux segments de droite 6 parallèles sensiblement à la surface de l'eau. Seen from the front (Figure 2), that is to say seen from the swimming pool, the entry face of the loophole has the shape of two semicircles 5 connected by two straight lines 6 parallel substantially to the surface of the water.
L'ouverture 7 de la meurtrière vers l'écumeur de surface 3 présente une forme identique à celle de la face d'entrée, mais elle est de dimensions plus réduites. The opening 7 of the loophole towards the surface skimmer 3 has a shape identical to that of the entry face, but it is of more reduced dimensions.
En vue de dessus ou bien dans une vue en coupe selon un plan parallèle à la surface de l'eau (figure 3), la meurtrière présente une forme d'hyperbole. Cette forme hydrodynamique permet à l'eau se trouvant près de la paroi 2 de la piscine d'être aspirée par la pompe. In top view or in a sectional view along a plane parallel to the surface of the water (Figure 3), the loophole presents a form of hyperbola. This hydrodynamic shape allows the water near the wall 2 of the pool to be sucked in by the pump.
Pour conserver l'étanchéité de la piscine, la meurtrière 1 doit être montée de façon étanche. La figure 3 montre comment elle est fixée. Dans cet exemple, un mur en béton 8 est recouvert d'un revêtement 9 en matière synthétique. Ce dernier est pris en sandwich entre deux joints 10 et le tout est vissé sur la meurtrière 1 à l'aide d'une bride 11 et de vis 12. To keep the pool watertight, the loophole 1 must be mounted in a leaktight manner. Figure 3 shows how it is attached. In this example, a concrete wall 8 is covered with a covering 9 made of synthetic material. The latter is sandwiched between two seals 10 and the whole is screwed onto the loophole 1 using a flange 11 and screws 12.
L'enjoliveur 4 vient recouvrir la bride 11 sur laquelle il vient s'encliqueter. La forme de cet enjoliveur 4 est dans la continuité de celle de la meurtrière 1. La section de l'enjoliveur présente une forme semi-circulaire se raccordant à la forme de la meurtrière. Ainsi, l'écoulement de l'eau n'est pas perturbé par cet enjoliveur. The hubcap 4 covers the flange 11 on which it snaps. The shape of this hubcap 4 is in continuity with that of the loophole 1. The section of the hubcap has a semi-circular shape connecting to the shape of the loophole. Thus, the flow of water is not disturbed by this trim.
Du côté de l'écumeur de surface 3, la meurtrière 1 présente un flasque 13 de forme rectangulaire venant se fixer sur l'entrée de l'écumeur de surface 3, par collage par exemple. On the side of the surface skimmer 3, the loophole 1 has a flange 13 of rectangular shape coming to be fixed on the entry of the surface skimmer 3, by gluing for example.
Comme il va de soi, l'invention ne se limite pas aux formes d'exécution décrites ci-dessus à titre d'exemple, elle en embrasse, au contraire, toutes les variantes. It goes without saying that the invention is not limited to the embodiments described above by way of example, on the contrary, it embraces all of the variants thereof.
