Description

DISPOSITIF DE REFROIDISSEMENT POUR ENSEMBLE COMPACT DE POMPAGE ET DE FILTRATION POUR BASSTN DE PISCINE. COOLING DEVICE FOR COMPACT PUMPING AND FILTRATION ASSEMBLY FOR POOL BASSTN.
L'invention se rattache au secteur technique des moyens de filtration de l'eau d'un bassin de piscine notamment.The invention relates to the technical sector of water filtration means of a swimming pool in particular.
Il est connu, pour assurer la filtration de l'eau d'un bassin de piscine, d'utiliser des ensembles qui intègrent les fonctionnalités d'un système traditionnel, à savoir essentiellement le pompage de l'eau, la filtration de l'eau et le refoulement de cette dernière dans le bassin de la piscine. Pour l'essentiel, ces ensembles compacts comprennent deux parties distinctes.It is known, to ensure the filtration of water in a swimming pool, to use assemblies which integrate the functionalities of a traditional system, namely essentially pumping water, filtering water and the backflow of the latter into the pool. Essentially, these compact sets include two separate parts.
L'une de ces parties est destinée à être immergée dans l'eau du bassin de la piscine, et reçoit les moyens de filtration de tous types connus et appropriés. L'autre partie est située en dehors du bassin de la piscine et reçoit au moins une pompe d'aspiration et de refoulement. Des tuyauteries de liaison sont disposées entre les deux parties, pour relier les moyens de filtration aux moyens de pompage. En outre, la partie immergée dans l'eau du bassin de la piscine présente, généralement, au moins une buse de refoulement de l'eau aspirée. Chacune des parties constitue un caisson, lesdites parties étant protégées par un couvercle. De même, ces deux parties peuvent être indépendantes l'une de l'autre et reliées par tout moyen connu pour constituer un ensemble unitaire ou bien, ces deux parties peuvent former, par moulage, ou tout autre procédé de fabrication, un ensemble compact unitaire. A partir de cette conception, on distingue essentiellement, deux formes de réalisations.One of these parts is intended to be immersed in the water of the swimming pool basin, and receives filtration means of all known and appropriate types. The other part is located outside the pool and receives at least one suction and discharge pump. Connecting pipes are arranged between the two parts, to connect the filtration means to the pumping means. In addition, the part immersed in the water of the swimming pool basin generally has at least one nozzle for discharging the sucked water. Each of the parts constitutes a box, said parts being protected by a cover. Likewise, these two parts can be independent of each other and connected by any known means to constitute a unitary assembly or else, these two parts can form, by molding, or any other manufacturing process, a unitary compact unit. . From this conception, there are essentially two forms of achievement.
Comme il ressort de l'enseignement du brevet FR 8318248 dont le demandeur de la présente est également titulaire, l'ensemble concerne un bloc compact constituant transversalement un cavalier en forme de U renversé, afin d'être disposé à cheval sur le rebord de la piscine. Ou bien, comme il ressort par exemple de l'enseignement du brevet FR 9412773 dont le demandeur de la présente est également titulaire, l'ensemble compact, peut constituer directement un panneau ou escalier filtrant en ce sens que la partie destinée à être immergée dans l'eau du bassin de la piscine est agencée pour être accouplée directement avec les autres panneaux constitutifs du bassin.As is clear from the teaching of the patent FR 8318248 which the applicant of the present also holds, the assembly relates to a compact block constituting transversely a rider in the shape of an inverted U, in order to be disposed astride the edge of the swimming pool. Or, as is apparent, for example, from the teaching of patent FR 9412773, of which the applicant here is also the holder, the compact assembly can directly constitute a filtering panel or staircase in the sense that the part intended to be immersed in the water in the pool is arranged to be coupled directly with the other constituent panels of the pool.
Comme indiqué précédemment, une tuyauterie est disposée entre les deux compartiments de filtration et de pompage. Quelle que soit la forme de réalisation, les deux compartiments de filtration et de pompage doivent être séparés, notamment au niveau des tuyauterie de liaison, par des agencements évitant la pénétration de l'eau par débordement et/ou éclaboussures dans le compartiment de pompage, étant donné qu'il n'est pas concevable que le compartiment de pompage reçoive, ne serait ce que par accident, une partie de l'eau du bassin de la piscine. En outre, il est nécessaire de créer une ventilation naturelle ou forcée au niveau du compartiment de pompage, pour permettre à la ou les pompes de travailler dans de bonnes conditions, en évitant tout effet de surchauffe. Pour cette raison, étant considéré par ailleurs, que le compartiment de pompage ne peut pas être mis directement en communication à l'air libre, compte tenu des intempéries, il est nécessaire de ménager au niveau de la séparation entre les deux compartiments, une fente ou autre, apte à laisser passer un film d'air suffisant pour permettre l'aération du compartiment de pompage. La présence de ce film d'air ne permet donc pas de séparer de manière totalement étanche les deux compartiments. Dans ces conditions, on ne peut totalement exclure le risque, certes réduit, que le compartiment de pompage reçoive accidentellement une partie de l'eau que contient le compartiment immergé de filtration.As indicated above, a pipe is arranged between the two filtration and pumping compartments. Whatever the embodiment, the two filtration and pumping compartments must be separated, in particular at the level of the connecting pipes, by arrangements preventing the penetration of water by overflowing and / or splashing into the pumping compartment, since it is not conceivable that the pumping compartment receives, if only by accident, part of the water from the swimming pool basin. In addition, it is necessary to create natural or forced ventilation at the level of the pumping compartment, to allow the pump or pumps to work in good conditions, avoiding any effect of overheating. For this reason, being considered furthermore, that the pumping compartment cannot be brought directly into communication with the open air, taking into account the bad weather, it is necessary to provide at the level of the separation between the two compartments, a slot or the like, capable of allowing a sufficient film of air to pass through to allow the ventilation of the pumping compartment. The presence of this air film therefore does not allow the two compartments to be completely sealed. Under these conditions, we cannot totally exclude the risk, admittedly reduced, that the pumping compartment accidentally receives part of the water contained in the submerged filtration compartment.
Ce problème est d'autant plus réel, dans le cas d'un panneau de filtration où le niveau de l'eau dans le compartiment immergé est beaucoup plus proche de la séparation entre les deux compartiments et par conséquent, beaucoup plus proche de la fente pour le passage de l'air de recyclage. A noter également que ces dispositions ne permettent pas une réelle circulation de l'air qui a tendance à être confiné.This problem is all the more real in the case of a filtration panel where the water level in the submerged compartment is much closer to the separation between the two compartments and therefore much closer to the slot. for the passage of recycling air. Note also that these provisions do not allow real air circulation which tends to be confined.
L'invention s'est fixée pour but de remédier à ces inconvénients, de manière simple, sûre, efficace et rationnelle.The object of the invention is to remedy these drawbacks in a simple, safe, effective and rational manner.
Le problème technique que se propose de résoudre l'invention, est d'avoir une meilleure étanchéité entre les deux compartiments de filtration et de pompage, afin d'éviter tout risque accidentel de passage d'eau entre les deux compartiments, tout en ayant pour objectif de pouvoir assurer le refroidissement, ou plus exactement l'aération, du compartiment de pompage.The technical problem which the invention proposes to solve is to have a better seal between the two filtration and pumping compartments, in order to avoid any accidental risk of passage of water between the two compartments, while having for objective of being able to ensure the cooling, or more exactly the aeration, of the pumping compartment.
Pour résoudre un tel problème, il a été conçu et mis au point un dispositif de refroidissement applicable notamment à un ensemble compact de pompage et de filtration pour bassin de piscine comprenant d'une manière connue, deux parties distinctes dont l'une est immergée dans l'eau et reçoit notamment au moins un élément filtrant, au moins une buse de refoulement et des tuyauteries de liaison avec la deuxième partie qui est située en dehors du bassin et qui reçoit au moins une pompe d'aspiration et de refoulement. Selon l'invention, l'ensemble est remarquable en ce que :To solve such a problem, a cooling device has been designed and developed which can be applied in particular to a compact assembly. pumping and filtration system for swimming pools comprising, in a known manner, two separate parts, one of which is immersed in water and receives in particular at least one filter element, at least one discharge nozzle and connecting pipes with the second part which is located outside the basin and which receives at least one suction and discharge pump. According to the invention, the assembly is remarkable in that:
- les deux parties sont séparées d'une manière étanche, ou quasi étanche,- the two parts are separated in a sealed or almost sealed manner,
- la partie recevant la pompe est en communication avec au moins une troisième partie,- the part receiving the pump is in communication with at least a third part,
- chacune des parties constitue un caisson, lesdites parties étant protégées par un couvercle,each of the parts constitutes a box, said parts being protected by a cover,
- le couvercle ou partie de couvercle correspondant à la troisième partie, présente des agencements pour mettre cette troisième partie en communication avec l'air extérieur.- The cover or cover part corresponding to the third part, has arrangements for putting this third part in communication with the outside air.
Autrement dit, compte tenu des caractéristiques à la base de l'invention, le problème technique que se propose de résoudre l'invention, est non plus de gérer les éventuels passages d'eau entre le compartiment d'aspiration et le compartiment de pompage mais de faire rentrer de l'air venant à l'extérieur tout en évitant les éventuels risques de passage d'eau provenant de l'extérieur, à savoir essentiellement l'eau de pluie, la fonte des neiges...In other words, taking into account the characteristics underlying the invention, the technical problem which the invention proposes to solve is no longer to manage any water passages between the suction compartment and the pumping compartment but to bring in air coming from outside while avoiding the possible risks of passage of water coming from the outside, namely essentially rain water, melting snow ...
Pour résoudre le problème posé d'assurer l'aération du compartiment de pompage et, par conséquent, de mettre la troisième partie de l'ensemble compact en communication avec l'air extérieur, les agencements du couvercle ou de la partie de couvercle sont constitués par une zone présentant une pluralité de perforations débouchantes.To solve the problem posed of ensuring the ventilation of the pumping compartment and, consequently, of putting the third part of the compact assembly in communication with the outside air, the arrangements of the cover or of the cover part consist of an area having a plurality of through perforations.
Pour résoudre le problème posé d'éviter tout passage accidentel d'eau de pluie, ou autre, dans le compartiment de pompage, la troisième partie et la partie recevant la ou les pompes, sont séparées par des agencements permettant le passage de l'air tout en évitant le passage de l'eau éventuellement contenue dans ladite troisième partie.To solve the problem of avoiding any accidental passage of rainwater, or other, in the pumping compartment, the third part and the part receiving the pump or pumps, are separated by arrangements allowing the passage of air. while avoiding the passage of the water possibly contained in said third part.
Dans ce but, différentes formes de réalisation peuvent être envisagées.To this end, different embodiments can be envisaged.
Par exemple, les agencements de séparation sont constitués par une surface inclinée ou bien les agencements de séparation sont constitués par un espace vide en creux partiellement obturé par une nervure du couvercle pour constituer une chicane avec système d'évacuation de l'eau au droit de la chicane.For example, the separation arrangements are constituted by an inclined surface or else the separation arrangements are constituted by an empty hollow space partially closed by a rib of the cover to constitute a baffle with water evacuation system at the right of chicanery.
De même, pour éviter tout risque de ruissellement au niveau de la face interne du couvercle, cette dernière présente à proximité du compartiment de pompage, une nervure transversale faisant office de larmier.Similarly, to avoid any risk of runoff at the inner face of the cover, the latter has, near the pumping compartment, a transverse rib serving as a drip line.
Pour résoudre le problème posé de réaliser un ensemble compact et unitaire la troisième partie est disposée dans le même plan que la partie recevant la ou les pompes et d'une manière sensiblement parallèle en faisant office de goulotte. Avantageusement, le fond de la troisième partie est percé pour l'évacuation de l'eau éventuelle qu'elle peut contenir. Le fond de la troisième partie est relié à une conduite d'évacuation.To solve the problem of making a compact and unitary unit, the third part is arranged in the same plane as the part receiving the pump or pumps and in a substantially parallel manner by acting as a chute. Advantageously, the bottom of the third part is pierced for the evacuation of any water that it may contain. The bottom of the third part is connected to an evacuation pipe.
Toujours en ayant pour objectif d'abaisser la température au niveau du compartiment de pompage, il est apparu intéressant de mettre en communication l'admission d'air du moteur directement avec l'extérieur. Pour résoudre un tel problème, la troisième partie est mise en communication avec la pompe d'aspiration et de refoulement au moyen d'un organe tabulaire dont l'une des extrémités débouche desdites parties tandis que l'autre extrémité présente des agencements d'accouplement avec l'admission d'air du moteur de la pompe.Still with the objective of lowering the temperature at the level of the pumping compartment, it appeared advantageous to put the engine air intake in communication directly with the outside. To solve such a problem, the third part is placed in communication with the suction and discharge pump by means of a tabular member, one end of which opens out from said parts while the other end has coupling arrangements. with the air intake from the pump motor.
Compte tenu de ces dispositions, il en résulte que l'air est aspiré directement à l'extérieur pour être dirigé au niveau du moteur de la pompe d'aspiration, de sorte que l'air chaud en résultant est immédiatement rejeté à l'extérieur, réalisant ainsi un parfait échange thermique.In view of these provisions, it follows that the air is sucked directly outside to be directed to the level of the motor of the suction pump, so that the resulting hot air is immediately rejected to the outside. , thus achieving a perfect heat exchange.
Pour résoudre le problème posé d'abaisser la température à l'intérieur du caisson, recevant la pompe d'aspiration et de refoulement, la zone de la troisième partie dans laquelle débouche l'organe tabulaire présente des parois transversales et latérales conformées pour constituer une enceinte étanche.To solve the problem of lowering the temperature inside the box, receiving the suction and discharge pump, the area of the third part into which the tabular member opens has transverse and lateral walls shaped to constitute a waterproof enclosure.
Des résultats avantageux sont obtenus, lorsque la paroi transversale est située à peu près au milieu pour séparer la troisième partie en deux zones très sensiblement équivalentes. Compte tenu de l'ensemble de ces caractéristiques, et dans le but de diminuer de manière importante le coût de fabrication, tout en ayant pour objectif d'obtenir un ensemble compact et unitaire, ce dernier est obtenu par rotomoulage, étant bien entendu que d'autres procédés peuvent être utilisés : injection de matière plastique, projection de polyester, thermoformage.Advantageous results are obtained when the transverse wall is situated approximately in the middle to separate the third part into two very substantially equivalent zones. Given all of these characteristics, and with the aim of significantly reducing the manufacturing cost, while having the objective of obtaining a compact and unitary assembly, the latter is obtained by rotational molding, it being understood that d Other processes can be used: plastic injection, polyester spraying, thermoforming.
L'invention est exposée ci-après plus en détail à l'aide des figures des dessins annexés, dans lesquels : La figure 1 est une vue en perspective d'un exemple de réalisation de l'ensemble compact de pompage et de filtration, ledit ensemble étant représenté avant la mise en place des couvercles.The invention is set out below in more detail with the aid of the figures of the appended drawings, in which: FIG. 1 is a perspective view of an embodiment of the compact pumping and filtration assembly, said assembly being shown before the installation of the covers.

Figure 3 is a longitudinal sectional view of the assembly according to a first embodiment.

La figure 6 est une vue en coupe longitudinale considérée selon la ligne 6-6 de la figure 5.FIG. 6 is a view in longitudinal section considered along line 6-6 of FIG. 5.
Pour une meilleure compréhension de la suite de la description, on rappelle que l'ensemble compact de pompage et de filtration comprend deux parties distinctes (A) et (B). La partie (A) constitue directement un caisson et est destinée à être immergée dans l'eau du bassin de la piscine. La partie (A) reçoit au moins un élément filtrant (1) et au moins une buse de refoulement (2). Par ailleurs, la face avant et/ou les faces latérales de la partie (A) immergée dans l'eau, présentent, d'une manière parfaitement connue pour un homme du métier, des ouvertures connues sous le nom de skimmers, pour le passage de l'eau en provenance du bassin de la piscine. L'autre partie (B) constitue également un caisson situé à l'extérieur du bassin de la piscine et reçoit, au moins une pompe d'aspiration et de refoulement (3). Des tayauteries (4) assurent la liaison entre le compartiment de filtration et le compartiment de pompage.For a better understanding of the rest of the description, it is recalled that the compact pumping and filtration assembly includes two separate parts (A) and (B). Part (A) directly constitutes a box and is intended to be immersed in the water of the swimming pool basin. The part (A) receives at least one filter element (1) and at least one delivery nozzle (2). Furthermore, the front face and / or the side faces of the part (A) immersed in water, have, in a manner perfectly known to a person skilled in the art, openings known as skimmers, for the passage water from the pool. The other part (B) also constitutes a box located outside the swimming pool basin and receives, at least one suction and discharge pump (3). Piping (4) provides the connection between the filtration compartment and the pumping compartment.
L'élément de filtration (1) est disposé dans un support (5) dont le fond est relié par l'intermédiaire d'une crépine au moyen d'une tuyauterie (4a) à la pompe (3). Une autre tuyauterie (4b) assure le refoulement de l'eau aspirée dans le bassin de la piscine, en combinaison avec notamment la buse de refoulement (2). Ces dispositions techniques de filtration ne sont pas décrites en détail car parfaitement connues pour un homme du métier et peuvent faire l'objet de différentes variantes d'exécution. De même, les deux parties (A) et (B) sont reliées entre elles, soit directement, soit de manière rapportée, pour constituer un ensemble compact unitaire. L'ensemble ainsi constitué est conformé soit pour être disposé à cheval sur le rebord des parois du bassin de la piscine, soit pour constituer directement un panneau ou escalier de filtration, la partie (A) présentant dans ce cas, tout agencement pour être fixée en combinaison et en alignement avec les autres panneaux constitutifs du bassin de la piscine. Suivant une caractéristique à la base de l'invention, les deux parties (A) et (B) sont séparées notamment au niveau des tayauteries (4) d'une manière étanche, au moyen par exemple, d'une cloison (6). La partie (B) recevant la pompe (3) est en communication avec au moins une troisième partie (C). Un couvercle (7) assure l'obturation des deux parties (C) et (A), tandis qu'un couvercle (7c) assure l'obturation du compartiment de pompage (B). Bien évidemment, sans pour cela sortir du cadre de l'invention, le couvercle (7) peut être réalisé en plusieurs éléments correspondant à chacune des parties (A) (B) et (C).The filter element (1) is arranged in a support (5), the bottom of which is connected via a strainer by means of a pipe (4a) to the pump (3). Another piping (4b) ensures the discharge of the water sucked into the swimming pool, in combination with in particular the discharge nozzle (2). These technical filtration provisions are not described in detail since they are perfectly known to a person skilled in the art and can be the subject of different variant embodiments. Likewise, the two parts (A) and (B) are interconnected, either directly or in an attached manner, to form a unitary compact assembly. The assembly thus formed is shaped either to be disposed astride the edge of the walls of the swimming pool basin, or to directly constitute a filtration panel or staircase, the part (A) having in this case, any arrangement to be fixed in combination and in alignment with the other constituent panels of the swimming pool basin. According to a characteristic at the base of the invention, the two parts (A) and (B) are separated in particular at the level of the tayauteries (4) in a sealed manner, by means for example, of a partition (6). The part (B) receiving the pump (3) is in communication with at least a third part (C). A cover (7) ensures the closure of the two parts (C) and (A), while a cover (7c) provides the closure of the pumping compartment (B). Obviously, without departing from the scope of the invention, the cover (7) can be made of several elements corresponding to each of the parts (A) (B) and (C).
Le couvercle (7) notamment, présente des agencements pour mettre la troisième partie (C) en communication avec l'air extérieur. Avantageusement, le couvercle présente, au niveau de cette troisième partie (C), une pluralité de perforations (7a) débouchantes. Cette troisième partie (C) est disposée dans le même plan que la partie (B) recevant la ou les pompes (3) et de manière essentiellement parallèle en faisant office de goulotte (8). Cette goulotte (8) est donc en communication par au moins une ouverture (9) avec le compartiment de la partie (B) recevant la ou les pompes. Etant donné que la goulotte (8) est en communication avec l'air extérieur, au moyen des perforations (7a), il y aura une circulation d'air au niveau du compartiment de pompage et de l'espace libre de communication (9). Cette circulation d'air permet de refroidir la ou les pompes (3).The cover (7) in particular has arrangements for placing the third part (C) in communication with the outside air. Advantageously, the cover has, at this third part (C), a plurality of openings (7a). This third part (C) is arranged in the same plane as the part (B) receiving the pump or pumps (3) and in an essentially parallel manner by acting as a chute (8). This chute (8) is therefore in communication through at least one opening (9) with the compartment of the part (B) receiving the pump or pumps. Since the chute (8) is in communication with the outside air, by means of the perforations (7a), there will be an air circulation at the level of the pumping compartment and the free communication space (9). . This air circulation makes it possible to cool the pump (s) (3).
Suivant une autre caractéristique, la goulotte (8) et le compartiment de pompage (B) sont séparés par des agencements permettant, comme indiqué, le passage de l'air tout en évitant le passage de l'eau, éventuellement contenue dans ladite goulotte.According to another characteristic, the chute (8) and the pumping compartment (B) are separated by arrangements allowing, as indicated, the passage of air while avoiding the passage of water, possibly contained in said chute.
Dans l'exemple de réalisation illustré figure 3, la séparation entre la goulotte (8) et le compartiment de pompage s'effectae par une surface inclinée (10).In the embodiment illustrated in Figure 3, the separation between the chute (8) and the pumping compartment is effected by an inclined surface (10).
Dans l'exemple de réalisation illustré figure 4, la goulotte (8) est reliée au compartiment de pompage par un espace vide en creux (1 1) destiné à être partiellement obturé par une nervure (7b) du couvercle, afin de constituer, en combinaison, une chicane.In the embodiment illustrated in Figure 4, the chute (8) is connected to the pumping compartment by a hollow hollow space (1 1) intended to be partially closed by a rib (7b) of the cover, in order to constitute, in combination, a chicane.
Pour éviter tout effet de ruissellement au niveau de la face interne du couvercle (7), cette dernière présente transversalement, sur la totalité de sa largeur et à proximité de la séparation avec le compartiment de pompage, une nervure (7d) faisant office de larmier.To avoid any trickling effect on the internal face of the cover (7), the latter has transversely, over its entire width and near the separation with the pumping compartment, a rib (7d) serving as a drip line .
Le fond de la troisième partie (C) ou goulotte (8) est percé pour l'évacuation de l'eau de pluie ou autre. De même, le fond de la goulotte est relié à un conduit (12) branché par exemple, au tout à l'égout. Il en est de même au niveau de la partie en creux (11) recevant la nervure (7b).The bottom of the third part (C) or chute (8) is pierced for the evacuation of rainwater or the like. Similarly, the bottom of the chute is connected to a conduit (12) connected for example, to the main sewer. It is the same at the level of the hollow part (11) receiving the rib (7b).
Pour diminuer la température à l'intérieur du caisson (B) recevant la pompe (3), il est apparu avantageux de mettre en communication son moteur (3 a) directement avec l'air extérieur. Dans ce but, et comme le montre notamment la figure 5, la troisième partie (C), constituant la goulotte (8) en communication avec l'air extérieur par les perforations (7a) du couvercle, est en communication avec la pompe (3) au moyen d'un organe tabulaire (13). L'une des extrémités (13a) de l'organe tabulaire débouche dans la goulotte (8) et l'autre extrémité (13b) présente des agencements d'accouplement (14) avec l'admission d'air du moteur (3 a) de la pompe (3). Par exemple, ces agencements (14) sont constitués par un volume en forme de cloche, conformé pour coiffer la section externe de la partie correspondante du moteur de la pompe. Ce volume en cloche (14) présente un manchon (14a) pour l'accouplement de l'extrémité (13b) de l'organe tabulaire (13).To decrease the temperature inside the box (B) receiving the pump (3), it appeared advantageous to put its motor (3 a) in communication directly with the outside air. For this purpose, and as shown in particular in FIG. 5, the third part (C), constituting the chute (8) in communication with the outside air by the perforations (7a) of the cover, is in communication with the pump (3 ) by means of a tabular member (13). One end (13a) of the tabular organ opens into the chute (8) and the other end (13b) has coupling arrangements (14) with the air intake of the motor (3a) of the pump (3). For example, these arrangements (14) consist of a bell-shaped volume, shaped to cover the external section of the corresponding part of the pump motor. This bell-shaped volume (14) has a sleeve (14a) for coupling the end (13b) of the tabular member (13).
La zone (8a) de la goulotte dans laquelle débouche l'extrémité (13a) de l'organe tabulaire (13) présente des parois transversale (15) et latérale (16), conformées pour constituer une enceinte étanche. Avantageuse, la paroi transversale (15) est située très sensiblement au milieu de la goulotte (8) pour la séparer en deux zones très sensiblement équivalentes (8a) et (8b). Eventuellement, la paroi transversale (15) est prolongée pour séparer en deux le caisson (B) recevant la pompe d'aspiration et de refoulement (3).The area (8a) of the chute into which opens the end (13a) of the tabular member (13) has transverse (15) and lateral (16) walls, shaped to constitute a sealed enclosure. Advantageously, the transverse wall (15) is located very substantially in the middle of the chute (8) to separate it into two very substantially equivalent zones (8a) and (8b). Optionally, the transverse wall (15) is extended to separate the box (B) receiving the suction and discharge pump (3) in two.
Compte tenu de ces dispositions, il apparaît que l'air est aspiré directement à l'extérieur pour être dirigé au niveau du moteur (3 a) de la pompe, l'air en sortie du moteur étant immédiatement rejeté à l'extérieur, lui évitant ainsi de stagner à l'intérieur du caisson (B). On évite ainsi toute élévation anormale de température à l'intérieur du caisson recevant la pompe d'aspiration et de refoulement. Différents essais et mesures ont montré que l'on obtient à l'intérieur du caisson (B) une température très sensiblement égale à la température de l'air extérieur.In view of these provisions, it appears that the air is sucked in directly from the outside to be directed to the level of the motor (3 a) of the pump, the air leaving the motor being immediately released to the outside, it thus avoiding stagnating inside the box (B). This avoids any abnormal temperature rise inside the box receiving the suction and discharge pump. Various tests and measurements have shown that a temperature very substantially equal to the temperature of the outside air is obtained inside the box (B).
Suivant une autre caractéristique, et compte tenu des dispositions constructives, l'ensemble compact selon l'invention peut avantageusement être obtenu par rotomoulage, injection de matière plastique, thermoformage, projection de polyester...According to another characteristic, and taking into account the constructive provisions, the compact assembly according to the invention can advantageously be obtained by rotational molding, plastic injection, thermoforming, polyester spraying ...
Les avantages ressortent bien de la description, en particulier on souligne et on rappelle la possibilité de séparer de manière étanche, le compartiment de pompage du compartiment de filtration, tout en permettant d'obtenir une circulation d'air au niveau du compartiment de pompage, avec le risque réduit, voire inexistant, que le compartiment de pompage soit soumis à l'action de l'eau de pluie ou autre, compte tenu d'une part, des agencements au niveau de la circulation de l'air et, d'autre part, de la forte probabilité que la goulotte ne sera jamais remplie d'eau ou autre.The advantages emerge clearly from the description, in particular the possibility of sealingly separating the pumping compartment from the filtration compartment is underlined and recalled, while allowing air circulation to be obtained at the level of the pumping compartment, with the reduced risk, or even non-existent, that the pumping compartment is subjected to the action of rainwater or other, taking into account on the one hand, the arrangements in terms of air circulation and, on the other hand, the high probability that the chute will never be filled with water or the like.
On observe également que la mise en communication du moteur de la pompe avec l'air extérieur dans les conditions indiquées permet de diminuer d'une manière significative la température à l'intérieur du caisson recevant ladite pompe. Il en résulte avantageusement une augmentation de la durée de vie du moteur et la suppression de tout effet néfaste sur les composants adjacents tels que le transformateur qui est soumis à l'influence de la température. On observe enfin qu'il est possible de diminuer la puissance absorbée du moteur, d'où une diminution des coûts. It is also observed that placing the pump motor in communication with the outside air under the conditions indicated makes it possible to significantly reduce the temperature inside the box receiving said pump. This advantageously results in an increase in the service life of the motor and the elimination of any harmful effect on the adjacent components such as the transformer which is subjected to the influence of temperature. Finally, it is observed that it is possible to reduce the absorbed power of the motor, hence a reduction in costs.
