Description

DISPOSITIF DE TRAITEMENT D'UNE EAU DE BASSIN À AMORÇAGE HYDRAULIQUE SIMPLIFIÉ, ET BASSIN ÉQUIPÉ D'UN TEL DISPOSITIF  SIMPLIFIED HYDRAULIC PRIMER BASED WATER TREATMENT DEVICE, AND BASIN EQUIPPED WITH SUCH A DEVICE
L'invention concerne un dispositif de traitement d'une eau de bassin à amorçage hydraulique simplifié. L'invention s'étend à un bassin, notamment un bassin de piscine, équipé d'un tel dispositif.  The invention relates to a device for treating a pond water with simplified hydraulic priming. The invention extends to a pool, including a pool pool, equipped with such a device.
Certains dispositifs de traitement d'eau comportent un dispositif de pompage dédié leur permettant d'assurer une circulation d'eau dans des unités de traitement. Après adjonction d'un tel dispositif de traitement sur un bassin, le problème de l'amorçage en eau du circuit hydraulique se pose. Il s'agit en particulier d'éviter la cavitation d'une pompe du circuit hydraulique d'un tel dispositif, qui peut être source d'un vieillissement prématuré ou d'une rupture de la pompe dès la mise en marche du dispositif. Or cette opération est généralement effectuée une fois pour toute par le professionnel en charge de l'installation.  Some water treatment devices include a dedicated pumping device enabling them to circulate water in treatment units. After the addition of such a treatment device on a pond, the problem of the water priming of the hydraulic circuit arises. In particular, it is a question of avoiding the cavitation of a pump of the hydraulic circuit of such a device, which can be a source of premature aging or of a rupture of the pump as soon as the device is put into operation. But this operation is usually done once and for all by the professional in charge of the installation.
Cependant, il est souhaitable de fournir une solution simple à l'installation et notamment à l'amorçage en eau du circuit hydraulique, pour permettre cette installation par un utilisateur sans connaissances spécifiques dans le domaine des circuits de filtration de piscine.  However, it is desirable to provide a simple solution to the installation and in particular the water priming of the hydraulic circuit, to allow this installation by a user without specific knowledge in the field of pool filtration circuits.
Or l'adjonction d'un dispositif de traitement (filtration, chloration, chauffage, etc.) de l'eau d'un bassin, notamment d'un bassin de piscine, est généralement complexe et coûteuse. En effet, que le bassin comporte déjà un circuit de filtration ou non, l'adjonction d'un dispositif de traitement additionnel nécessite le plus souvent l'intervention d'un spécialiste. En particulier un tel ajout nécessite généralement des travaux importants sur le gros œuvre de la piscine et/ou une intervention lourde dans le local technique rendant obligatoire l'intervention d'un professionnel. Dans tous les cas le problème de l'amorçage en eau du circuit se pose pour un utilisateur ne disposant ni de connaissances ni d'outils spécifiques dans ce domaine.  However, the addition of a treatment device (filtration, chlorination, heating, etc.) of the water of a pool, including a pool, is generally complex and expensive. Indeed, whether the pool already has a filtration circuit or not, the addition of an additional treatment device usually requires the intervention of a specialist. In particular such an addition generally requires major work on the shell of the pool and / or heavy intervention in the technical room requiring the intervention of a professional. In all cases the problem of the water priming of the circuit arises for a user having no knowledge or specific tools in this area.
A fortiori dans le cas d'un tel dispositif qui est amovible du bassin, le circuit hydraulique est vidé chaque fois qu'il est retiré de l'eau du bassin et doit donc être réamorcé chaque fois qu'il y est réinstallé (par exemple à chaque printemps). Or, pour un tel dispositif amovible, certains éléments du circuit hydraulique peuvent être plus ou moins en hauteur par rapport au niveau de l'eau du bassin selon le terrain sur lequel il est installé. A fortiori in the case of such a device that is removable basin, the hydraulic circuit is emptied each time it is removed from the pool water and must be rebooted each time it is reinstalled (eg every spring). However, for such a removable device, some elements of the circuit hydraulics may be more or less in height compared to the water level of the basin depending on the terrain on which it is installed.
L'invention vise donc à pallier ces inconvénients en proposant un nouveau dispositif de traitement d'une eau de bassin.  The invention therefore aims to overcome these disadvantages by proposing a new device for treating pond water.
L'invention vise en particulier à proposer un tel dispositif qui puisse être ajouté simplement à un bassin existant et donc sans modification lourde du bassin, en particulier qui ne nécessite pas de modifier les parois du bassin ou un circuit hydraulique préexistant.  The invention aims in particular to provide such a device that can be added simply to an existing pool and therefore without heavy modification of the basin, in particular that does not require modifying the walls of the pool or a pre-existing hydraulic circuit.
L'invention vise notamment à proposer un tel dispositif qui puisse être fixé (ou installé) et désinstallé sans vidange de la piscine, ou même pendant la baignade.  The invention aims in particular to provide such a device that can be fixed (or installed) and uninstalled without emptying the pool, or even while swimming.
L'invention vise également à proposer un tel dispositif qui puisse être amorcé en eau dans toutes conditions d'installation.  The invention also aims at providing such a device that can be primed with water under all installation conditions.
L'invention vise également à proposer un tel dispositif dont l'installation et la mise en route soient simples et rapides.  The invention also aims to provide such a device whose installation and startup are simple and fast.
Dans tout le texte, on utilise le terme "eau" pour toute composition aqueuse liquide. L'eau d'un bassin peut contenir des sels dissous, des éléments chimiques, des micro-organismes, etc.  Throughout the text, the term "water" is used for any aqueous liquid composition. The water in a pond may contain dissolved salts, chemical elements, micro-organisms, etc.
De même, dans tout le texte, on utilise le terme "traitement" de façon générique pour tout type de conditionnement seul ou en combinaison d'une eau de bassin : chloration, filtration, salage, traitement aux UV, chauffage, refroidissement, oxygénation, coloration...  Similarly, throughout the text, the term "treatment" is used generically for any type of conditioning alone or in combination with a pond water: chlorination, filtration, salting, UV treatment, heating, cooling, oxygenation, coloring...
Pour ce faire, l'invention concerne un dispositif de traitement d'une eau de bassin comprenant :  To this end, the invention relates to a device for treating a pond water comprising:
- un dispositif de pompage de l'eau interposé dans un circuit hydraulique pour y générer un débit d'eau entre au moins une bouche d'aspiration de l'eau du bassin et au moins une bouche de refoulement de l'eau du bassin,  a device for pumping water interposed in a hydraulic circuit in order to generate a flow of water between at least one suction mouth of the water of the basin and at least one discharge mouth of the water of the basin,
- une unité de traitement de l'eau interposée dans le circuit hydraulique pour conditionner de l'eau y circulant,  a water treatment unit interposed in the hydraulic circuit for conditioning the water circulating therein,
caractérisé en ce que - au moins une bouche d'aspiration dudit circuit hydraulique présentant une section de passage dans le sens de l'aspiration, présente, dans le sens du refoulement, une section de passage non-nulle inférieure à la section de passage dans le sens de l'aspiration, characterized in that - At least one suction mouth of said hydraulic circuit having a passage section in the direction of suction, has, in the discharge direction, a non-zero passage section less than the passage section in the direction of the suction,
- le circuit hydraulique comporte en outre un raccord, dit raccord d'amorçage, formant une entrée d'eau dans le circuit hydraulique, adapté pour permettre d'amorcer le circuit hydraulique avec de l'eau.  - The hydraulic circuit further comprises a connection, said priming connection, forming a water inlet in the hydraulic circuit, adapted to allow to prime the hydraulic circuit with water.
Un dispositif selon l'invention peut être installé par un utilisateur du bassin sans connaissances particulières.  A device according to the invention can be installed by a user of the pool without special knowledge.
L'invention permet, pour la première fois, de proposer un dispositif de traitement de l'eau pour équiper des piscines qui ne pouvaient pas en comporter, notamment pour équiper des piscines ne comportant pas de circuit hydraulique intégré de filtrage et/ou de chauffage, par exemple les piscines hors-sol ou démontables.  The invention makes it possible, for the first time, to propose a water treatment device for equipping pools that could not contain them, in particular for equipping pools that do not have an integrated hydraulic filtering and / or heating circuit. for example above-ground or removable pools.
Les inventeurs ont déterminé que réduire la section de passage de la bouche d'aspiration dans le sens du refoulement permet de façon astucieuse de créer une perte de charge dans le sens du refoulement par ladite bouche d'aspiration. Cette perte de charge permet de remplir facilement l'ensemble du circuit hydraulique du dispositif de traitement. Notamment cette perte de charge permet d'équilibrer les pertes de charge éventuellement formées par le dispositif de pompage et l'(les) unité(s) de traitement lorsqu'ils sont à l'arrêt.  The inventors have determined that reducing the passage section of the suction mouth in the discharge direction cleverly allows to create a pressure drop in the direction of discharge by said suction mouth. This pressure drop makes it easy to fill the entire hydraulic circuit of the treatment device. In particular, this pressure drop makes it possible to balance the pressure drops that may be formed by the pumping device and the treatment unit (s) when they are stopped.
En revanche, ils ont déterminé contre toute attente qu'il est nécessaire de conserver une section de passage non-nulle dans le sens du refoulement, c'est-à-dire de former une fuite contrôlée, afin d'autoriser un reflux de fluide par la bouche d'aspiration. Le reflux est certes limité par rapport à l'aspiration qui se fait par une section de passage plus importante, mais non-nul. Cette section de passage dans le sens du refoulement par la bouche d'aspiration permet notamment d'évacuer de l'air emprisonné dans le circuit hydraulique.  On the other hand, they have unexpectedly determined that it is necessary to maintain a non-zero passage section in the direction of the discharge, that is to say to form a controlled leak, in order to allow a reflux of fluid by the suction mouth. The reflux is certainly limited compared to the suction which is made by a larger passage section, but non-zero. This passage section in the direction of the discharge through the suction port allows in particular to evacuate air trapped in the hydraulic circuit.
Un utilisateur du bassin peut ainsi aisément amorcer le circuit hydraulique d'un dispositif selon l'invention en l'emplissant d'eau. En effet, la double fonction de perte de charge et d'autorisation d'un reflux d'air permet le remplissage simple du circuit hydraulique (à condition toutefois qu'aucune des unités de traitement de l'eau ne comporte de vanne fermée ou de pertes de charge importantes lorsqu'elles sont à l'arrêt). A user of the basin can thus easily prime the hydraulic circuit of a device according to the invention by filling it with water. Indeed, the dual function of pressure drop and authorization of an air reflux allows the simple filling of the hydraulic circuit (provided, however, that none of the water treatment units has a closed valve or large pressure drops when they are stopped).
Ainsi lorsque de l'eau est injectée par un raccord d'amorçage - constituant un point de remplissage en eau du circuit hydraulique - à une pression suffisante, l'eau injectée repousse l'air du circuit hydraulique par une bouche de refoulement pour la portion de circuit hydraulique située en aval du raccord d'amorçage, et par la bouche d'aspiration pour la portion de circuit hydraulique situé en amont du raccord d'amorçage.  Thus when water is injected by a priming connection - constituting a water filling point of the hydraulic circuit - at a sufficient pressure, the injected water pushes the air of the hydraulic circuit by a discharge mouth for the portion hydraulic circuit located downstream of the priming connection, and by the suction port for the hydraulic circuit portion located upstream of the priming connection.
L'eau injectée dans le circuit hydraulique chasse l'air du circuit hydraulique au moins par une bouche d'aspiration présentant une section de passage non nulle dans un sens de refoulement par la bouche d'aspiration. Si la section de passage empêchait tout reflux d'air du circuit par la bouche d'aspiration, l'amorçage en eau du circuit ne serait pas possible : l'air emprisonné entre la bouche d'aspiration et le raccord d'amorçage serait comprimé à la pression de l'eau injectée mais resterait bloqué entre la bouche d'aspiration et le raccord d'amorçage.  Water injected into the hydraulic circuit expels air from the hydraulic circuit at least through a suction mouth having a non-zero passage section in a discharge direction through the suction mouth. If the passage section prevents any backflow of air from the circuit through the suction port, the water priming of the circuit would not be possible: the air trapped between the suction port and the priming connection would be compressed at the pressure of the injected water but would remain blocked between the suction mouth and the priming connection.
L'autorisation du reflux d'air dans le sens du refoulement par la bouche d'aspiration évite d'équiper le circuit hydraulique d'une bouche d'équilibrage des pressions à proximité de la bouche d'aspiration pour l'évacuation de l'air emprisonné dans le circuit hydraulique.  The authorization of the backflow of air in the direction of the discharge by the suction mouth avoids equipping the hydraulic circuit with a balancing mouth pressures near the suction mouth for the evacuation of the air trapped in the hydraulic circuit.
Ainsi, une portion amont du circuit hydraulique située entre la bouche d'aspiration et un dispositif de pompage se remplit d'eau, jusqu'à ce que l'eau atteigne la section de passage réduite. Lorsque l'eau atteint cette section réduite, celle-ci crée une perte de charge importante qui limite le refoulement d'eau par la bouche d'aspiration. L'eau injectée par le raccord d'amorçage termine alors de remplir le reste du circuit hydraulique, notamment en aval du raccord d'amorçage.  Thus, an upstream portion of the hydraulic circuit located between the suction mouth and a pumping device fills with water, until the water reaches the reduced passage section. When the water reaches this reduced section, it creates a significant pressure drop that limits the water backflow through the suction port. The water injected by the priming connection then completes filling the rest of the hydraulic circuit, in particular downstream of the priming connection.
Avantageusement, l'eau d'amorçage injectée par un point de remplissage du circuit hydraulique est injectée à une pression supérieure au moins à la pression atmosphérique. Avantageusement elle est injectée à une pression strictement supérieure à la pression régnant au niveau de la bouche d'aspiration et de la bouche de refoulement lorsque le dispositif de traitement de l'eau est installé dans un bassin. Advantageously, the priming water injected by a filling point of the hydraulic circuit is injected at a pressure greater than at least atmospheric pressure. Advantageously, it is injected at a pressure that is strictly greater than the pressure at the level of the suction mouth and from the discharge mouth when the water treatment device is installed in a pond.
Un raccord d'amorçage selon l'invention permet de relier aisément le circuit hydraulique à une source d'eau sous pression par exemple telle qu'un robinet de réseau d'eau alimenté par un château d'eau, ou encore de l'eau sous pression fournie par une pompe, etc.  A priming connection according to the invention makes it possible to easily connect the hydraulic circuit to a pressurized water source, for example such as a water network tap supplied by a water tower, or even water. under pressure supplied by a pump, etc.
Un tel raccord est une entrée annexe d'eau qui n'est pas une bouche d'aspiration ni une bouche de refoulement du dispositif de traitement et qui permet l'amorçage, c'est-à-dire la mise en eau d'au moins une portion du circuit hydraulique avant la mise en marche du dispositif de pompage. Un tel raccord est adapté pour être relié à une source d'eau sous pression différente de la pompe du circuit hydraulique du dispositif de traitement selon l'invention.  Such a connection is an auxiliary water inlet which is not a suction mouth or a discharge mouth of the treatment device and which allows the priming, that is to say the impoundment of water. minus a portion of the hydraulic circuit before starting the pumping device. Such a coupling is adapted to be connected to a source of water under pressure different from the pump of the hydraulic circuit of the treatment device according to the invention.
Avantageusement un tel raccord permet au moins la mise en eau du dispositif de pompage et de toute conduite du circuit hydraulique située en amont de ce dispositif de pompage.  Advantageously, such a connection allows at least the watering of the pumping device and any pipe of the hydraulic circuit located upstream of the pumping device.
Un tel raccord facilite aussi le branchement du circuit hydraulique à une source extérieure en eau, par exemple à un robinet standard.  Such a coupling also facilitates the connection of the hydraulic circuit to an external source of water, for example to a standard faucet.
L'invention propose un dispositif de traitement dont l'amorçage est simple quelque soient les conditions dans lesquelles il est installé. En effet, lorsque le raccord d'amorçage est relié à une source d'alimentation en eau sous pression, l'ensemble du circuit hydraulique peut être rempli d'eau, même si certaines portions du circuit sont situées plus haut que la surface du bassin.  The invention proposes a treatment device whose initiation is simple whatever the conditions in which it is installed. Indeed, when the priming connection is connected to a source of water supply under pressure, the entire hydraulic circuit can be filled with water, even if certain portions of the circuit are located higher than the surface of the basin .
L'invention concerne tout particulièrement les dispositifs de traitement amovibles donc comportant des fixations simples rendant rapides la pose et la dépose d'un dispositif selon l'invention dans un bassin par un utilisateur sans connaissances particulières. Etant amovibles, les bouches d'aspiration et de refoulement d'un dispositif selon l'invention sont sorties de l'eau régulièrement (par exemple à chaque fin de saison, à l'automne, ou encore pour rendre son aspect esthétique d'origine au bassin). Or lorsque les bouches sont sorties de l'eau, l'eau du circuit hydraulique est évacuée de sorte qu'il est nécessaire de réamorcer le circuit hydraulique à chaque nouvelle installation du dispositif. Un réamorçage simple est donc particulièrement avantageux dans ce cas. The invention particularly relates to removable treatment devices thus having simple fasteners making quick the installation and removal of a device according to the invention in a pool by a user without special knowledge. Being removable, the suction and discharge mouths of a device according to the invention are out of the water regularly (for example at the end of the season, in autumn, or to make its original appearance at the pool). But when the mouths are out of the water, the water of the hydraulic circuit is evacuated so that it is necessary to reprime the hydraulic circuit at each new installation of the device. Simple reinforcement is therefore particularly advantageous in this case.
Avantageusement et selon l'invention, au moins une bouche d'aspiration est dotée d'un clapet adapté pour réduire sans l'annuler la section de passage de ladite bouche d'aspiration dans le sens du refoulement.  Advantageously and according to the invention, at least one suction mouth is provided with a valve adapted to reduce without canceling the passage section of said suction mouth in the discharge direction.
En particulier, avantageusement et selon l'invention, au moins une bouche d'aspiration est dotée d'un clapet anti-refoulement doté d'un orifice de reflux de section de passage inférieure à la section de passage de la bouche d'aspiration dans le sens de l'aspiration.  In particular, advantageously and according to the invention, at least one suction mouth is provided with a backflow valve provided with a lower cross-section discharge orifice to the passage section of the suction mouth in the sense of aspiration.
Un tel clapet autorise le passage d'eau dans le sens de l'aspiration par la bouche d'aspiration et réduit le refoulement d'eau par la bouche d'aspiration.  Such a valve allows the passage of water in the direction of suction through the suction port and reduces the water flow through the suction port.
Un tel clapet peut être de différentes natures et peut être rigide monté mobile, ou élastiquement déformable, ... Un tel clapet est avantageusement basé sur le principe d'un clapet anti-retour, mais dont la limitation de retour de fluide n'est pas complète. En particulier, un clapet selon l'invention peut être réalisé en formant un orifice de reflux dans un clapet anti-retour.  Such a valve can be of different natures and can be rigid mounted mobile, or elastically deformable, ... Such a valve is advantageously based on the principle of a non-return valve, but the limitation of fluid return is not complete. In particular, a valve according to the invention can be made by forming a reflux orifice in a non-return valve.
L'orifice de reflux permet d'autoriser un reflux de fluide, et notamment d'air, dans le sens du refoulement par la bouche d'aspiration. L'orifice est choisi de dimensions suffisamment inférieures à la dimension du clapet pour former une perte de charge importante dans le sens du refoulement d'eau par la bouche d'aspiration lorsque le circuit est en eau (donc amorcé).  The reflux orifice allows to allow a reflux of fluid, and in particular of air, in the direction of the discharge by the suction mouth. The orifice is chosen to be sufficiently smaller than the dimension of the valve to form a significant loss of pressure in the direction of water delivery through the suction mouth when the circuit is in water (thus primed).
L'air étant beaucoup moins visqueux que l'eau (dans des conditions atmosphériques habituelles), la perte de charge formée par un clapet percé d'un orifice de reflux est beaucoup plus faible pour l'air que pour l'eau. C'est pourquoi l'évacuation d'air poussé par de l'eau par l'orifice de reflux est aisée, et le refoulement d'eau par l'orifice de reflux l'est moins.  Since the air is much less viscous than water (under usual atmospheric conditions), the pressure loss formed by a valve pierced by a reflux orifice is much lower for air than for water. This is why the evacuation of air pushed by water through the reflux orifice is easy, and the discharge of water through the reflux port is less.
Ainsi un tel clapet ne s'oppose pas intégralement au passage de fluide dans le sens d'un refoulement par la bouche d'aspiration.  Thus such a valve does not completely oppose the passage of fluid in the direction of a discharge by the suction mouth.
Aussi, avantageusement et selon l'invention, l'orifice de reflux présente une section de passage dans le sens du refoulement comprise entre le dixième et le trentième de la section de passage dans le sens de l'aspiration de la bouche d'aspiration. Also, advantageously and according to the invention, the reflux orifice has a passage section in the direction of the discharge between the tenth and thirtieth of the passage section in the direction of suction of the suction mouth.
La section de passage (ou ouverture) formée par l'orifice de reflux est dimensionnée pour pouvoir laisser de l'air du circuit hydraulique s'échapper facilement lorsque l'air est repoussé par de l'eau injectée sous pression dans le circuit hydraulique.  The passage section (or opening) formed by the reflux port is sized to allow air from the hydraulic circuit to escape easily when the air is repelled by water injected under pressure in the hydraulic circuit.
Cependant, l'orifice de reflux présente une section de passage adaptée pour limiter le débit d'eau dans le sens d'un refoulement par la bouche d'aspiration. En particulier, l'orifice de reflux crée une perte de charge empêchant un équilibrage des pressions entre l'eau injectée sous pression dans le circuit hydraulique par un raccord d'amorçage et l'eau du bassin au niveau de la bouche d'aspiration, lorsque la pression dans le circuit hydraulique est supérieure à la pression dans le bassin.  However, the reflux orifice has a passage section adapted to limit the flow of water in the direction of a discharge by the suction mouth. In particular, the reflux orifice creates a pressure drop preventing a pressure equalization between the water injected under pressure into the hydraulic circuit by a priming connection and the water of the basin at the suction mouth, when the pressure in the hydraulic circuit is greater than the pressure in the basin.
Les inventeurs ont déterminé qu'un rapport entre section de passage dans le sens du refoulement et section de passage dans le sens de l'aspiration compris entre un dixième et un trentième est particulièrement avantageux, notamment un rapport d'environ un vingtième.  The inventors have determined that a ratio between the passage section in the direction of the discharge and the passage section in the direction of suction between one tenth and one thirtieth is particularly advantageous, especially a ratio of about one twentieth.
Le clapet est souple et peut se déformer pour autoriser le passage d'eau du bassin aspirée dans le circuit hydraulique par le dispositif de pompage.  The valve is flexible and can be deformed to allow the passage of water from the basin sucked into the hydraulic circuit by the pumping device.
Le clapet est avantageusement fixé en au moins un point de la bouche d'aspiration, notamment en un point périphérique de cette dernière.  The valve is advantageously fixed in at least one point of the suction mouth, in particular at a peripheral point of the latter.
De plus, la bouche d'aspiration forme avantageusement une butée (par un épaulement, un collet, ou équivalent) sur laquelle le clapet vient en butée sous l'effet d'un fluide circulant à contre-sens (d'aval en amont) dans le circuit hydraulique, c'est-à-dire refluant par bouche d'aspiration. Toute flexion du clapet dans le sens d'un refoulement de l'eau du circuit hydraulique vers le bassin est ainsi au moins limitée, sinon interdite.  In addition, the suction mouth advantageously forms a stop (by a shoulder, a collar, or equivalent) on which the valve abuts under the effect of a fluid flowing against the direction (downstream upstream) in the hydraulic circuit, that is to say ebb by suction mouth. Any bending of the valve in the direction of a discharge of water from the hydraulic circuit to the basin is thus at least limited, if not prohibited.
Le clapet est avantageusement en matériau élastomère tel que par exemple : en éthylène-propylène-diène monomère (EPDM), en caoutchouc naturel, en poly-isobutylène (PIB), ou équivalents. Il est en particulier réalisé dans un matériau souple et résistant aux conditions du bassin : par exemple il est résistant au chlore, aux sels, aux ultraviolets, etc. The valve is advantageously made of elastomeric material such as, for example: ethylene-propylene-diene monomer (EPDM), natural rubber, polyisobutylene (PIB), or the like. It is especially realized in a flexible and resistant material to the conditions of the basin: for example it is resistant to chlorine, salts, ultraviolet, etc.
De plus, avantageusement et selon l'invention, le clapet est à proximité d'une surface d'entrée de la bouche d'aspiration, du côté intérieur de cette surface.  In addition, advantageously and according to the invention, the valve is close to an inlet surface of the suction mouth, the inner side of this surface.
Une telle surface d'entrée est définie par une surface à partir de laquelle l'eau est dans la bouche d'aspiration et donc dans le circuit hydraulique. Elle est facilement représentée par un plan au contact d'au moins trois points des bords d'entrée de la bouche d'aspiration.  Such an inlet surface is defined by a surface from which the water is in the suction mouth and thus in the hydraulic circuit. It is easily represented by a plane in contact with at least three points of the inlet edges of the suction mouth.
De plus, avantageusement et selon l'invention, le raccord d'amorçage est adapté pour pouvoir être raccordé à un robinet standard d'habitation individuelle.  In addition, advantageously and according to the invention, the priming connector is adapted to be connected to a standard single dwelling faucet.
Un raccord d'amorçage selon l'invention est avantageusement standard de sorte qu'il est facile pour un utilisateur d'un dispositif de traitement amovible selon l'invention d'en amorcer le circuit hydraulique quelles que soient les conditions dans lesquelles ledit dispositif est installé.  A priming coupling according to the invention is advantageously standard so that it is easy for a user of a removable treatment device according to the invention to prime the hydraulic circuit regardless of the conditions under which said device is installed.
En effet, le raccord d'amorçage peut se trouver en n'importe quel point du circuit hydraulique. Or le circuit hydraulique peut comporter des dénivelés importants en fonction du terrain à proximité d'un bassin sur lequel il est disposé, de sorte qu'il présente des points hauts et des points bas.  Indeed, the priming connection can be at any point of the hydraulic circuit. However, the hydraulic circuit may have significant elevation changes depending on the terrain near a pool on which it is arranged, so that it has high points and low points.
Cependant, grâce à l'invention, même si le dispositif de pompage est situé en un point haut du circuit hydraulique, l'amorçage est simple et rapide.  However, thanks to the invention, even if the pumping device is located at a high point of the hydraulic circuit, priming is simple and fast.
En particulier, un utilisateur propriétaire d'une piscine individuelle doit être en mesure de raccorder simplement le raccord d'amorçage à un robinet de son habitation répondant à des normes ou conventions d'usage en termes de dimensions, de pression d'eau délivrée, etc.  In particular, a user owning an individual swimming pool must be able to simply connect the priming connector to a tap of his home meeting standards or conventions of use in terms of dimensions, water pressure delivered, etc.
Aussi, avantageusement et selon l'invention, le raccord d'amorçage est monté sur une conduite amont du circuit hydraulique s 'étendant entre une bouche d'aspiration à section de passage réduite dans le sens du refoulement et le dispositif de pompage. Le dispositif de pompage d'un dispositif de traitement selon l'invention est généralement situé en amont des unités de traitement de l'eau. C'est pourquoi, il est important que la portion amont du circuit hydraulique, c'est-à-dire que la portion située entre la bouche d'aspiration et le dispositif de pompage au moins, soit pleine d'eau au démarrage du dispositif de pompage afin d'éviter la cavitation de la pompe. Disposer le raccord d'amorçage dans cette portion du circuit permet de s'assurer que ladite conduite amont est remplie en première et que le dispositif de pompage ne rencontrera pas de bulles lors des premiers instants de fonctionnement. Also, advantageously and according to the invention, the priming connection is mounted on an upstream pipe of the hydraulic circuit extending between a suction mouth with reduced passage section in the discharge direction and the pumping device. The pumping device of a treatment device according to the invention is generally located upstream of the water treatment units. Therefore, it is important that the upstream portion of the hydraulic circuit, that is to say that the portion between the suction port and the pumping device at least, is full of water at startup of the device pumping to prevent cavitation of the pump. Placing the priming connection in this portion of the circuit makes it possible to ensure that said upstream pipe is filled first and that the pumping device will not encounter bubbles during the first moments of operation.
Idéalement, l'ensemble du circuit hydraulique est amorcé en eau au démarrage de la pompe.  Ideally, the entire hydraulic circuit is primed with water when the pump starts.
Alternativement ou en combinaison, avantageusement et selon l'invention, le circuit hydraulique est en outre équipé d'au moins une bouche de remplissage manuel pour pouvoir amorcer manuellement le circuit hydraulique en eau.  Alternatively or in combination, advantageously and according to the invention, the hydraulic circuit is further equipped with at least one manual filling mouth to be able to manually prime the hydraulic circuit in water.
Ainsi, un utilisateur du dispositif de traitement selon l'invention est en mesure de remplir le circuit hydraulique d'eau, sans pour autant disposer de source d'eau sous pression à proximité. Une telle bouche de remplissage manuel présente avantageusement une forme d'entonnoir prolongé d'une colonne d'eau reliée à son extrémité basse au circuit hydraulique, afin de fournir une pression suffisante au remplissage du circuit hydraulique.  Thus, a user of the treatment device according to the invention is able to fill the hydraulic circuit with water, without having a source of pressurized water nearby. Such a manual filling mouth advantageously has a funnel-shaped extended water column connected to its lower end to the hydraulic circuit, to provide sufficient pressure to fill the hydraulic circuit.
Le remplissage de la portion amont du circuit (entre bouche d'aspiration et dispositif de pompage) étant essentiel, la bouche de remplissage manuel est avantageusement disposée à proximité du dispositif de pompage.  Since the filling of the upstream portion of the circuit (between the suction mouth and the pumping device) is essential, the manual filling mouth is advantageously arranged close to the pumping device.
L'invention concerne également un dispositif de traitement d'une eau de bassin caractérisé en combinaison par tout ou partie des caractéristiques mentionnées ci-dessus ou ci-après.  The invention also relates to a basin water treatment device characterized in combination by all or some of the characteristics mentioned above or below.
L'invention concerne également un procédé de remplissage d'un dispositif de traitement d'une eau de bassin selon l'invention, dans lequel le raccord d'amorçage est raccordé à une source d'alimentation en eau à une pression adaptée pour remplir d'eau au moins une pompe du dispositif de pompage et une conduite amont du circuit hydraulique. The invention also relates to a method for filling a pond water treatment device according to the invention, in which the priming connection is connected to a source of water supply at a pressure adapted to fill with water at least one pump of the pumping device and an upstream pipe of the hydraulic circuit.
L'invention concerne également un procédé de remplissage d'un dispositif de traitement d'une eau de bassin caractérisé en combinaison par tout ou partie des caractéristiques mentionnées ci-dessus ou ci-après.  The invention also relates to a method of filling a pond water treatment device characterized in combination by all or some of the characteristics mentioned above or below.
L'invention peut s'étendre à un kit d'amélioration pour l'amorçage d'un dispositif de traitement d'une eau de bassin selon l'invention, comprenant :  The invention may be extended to an improvement kit for priming a device for treating a pond water according to the invention, comprising:
- une façade de bouche d'aspiration adaptée pour pouvoir être montée sur une bouche d'aspiration dudit dispositif de traitement et réduire sans l'annuler la section de passage de ladite bouche d'aspiration dans le sens du refoulement,  - A suction mouth face adapted to be mounted on a suction mouth of said treatment device and reduce without canceling the passage section of said suction mouth in the direction of the discharge,
- un raccord d'amorçage adapté pour pouvoir être monté en un point du circuit hydraulique, et adapté pour former une entrée d'eau dans le circuit hydraulique, afin de permettre d'amorcer le circuit hydraulique avec de l'eau.  - A priming fitting adapted to be mounted at a point in the hydraulic circuit, and adapted to form a water inlet in the hydraulic circuit, to allow to prime the hydraulic circuit with water.
L'invention concerne également un bassin équipé d'au moins un dispositif de traitement selon l'invention.  The invention also relates to a pool equipped with at least one treatment device according to the invention.
En particulier, avantageusement et selon l'invention, un tel bassin comporte en outre un circuit de filtration principal comprenant :  In particular, advantageously and according to the invention, such a basin further comprises a main filtration circuit comprising:
- un dispositif de pompage principal de l'eau interposé dans un circuit hydraulique principal pour y générer un débit d'eau entre au moins une bouche de récupération d'eau du bassin et au moins une bouche de refoulement d'eau du bassin,  a main water pumping device interposed in a main hydraulic circuit to generate a flow of water between at least one basin water recovery mouth and at least one water discharge mouth of the basin,
- au moins une unité de filtration principale de l'eau interposée dans le circuit hydraulique principal pour traiter de l'eau y circulant,  at least one main filtration unit for the water interposed in the main hydraulic circuit for treating the water circulating therein,
caractérisé en ce qu'il comporte au moins un dispositif de traitement selon l'invention et en ce que : characterized in that it comprises at least one treatment device according to the invention and in that:
- le circuit hydraulique principal du circuit de filtration principal est distinct du circuit hydraulique de chaque dispositif de traitement,  the main hydraulic circuit of the main filtration circuit is distinct from the hydraulic circuit of each treatment device,
- chaque bouche de récupération du circuit de filtration principal est distincte de chaque bouche d'aspiration de chaque dispositif de traitement, et chaque bouche de refoulement du circuit de filtration principal est distincte de chaque bouche de refoulement de chaque dispositif de traitement, each recovery mouth of the main filtration circuit is distinct from each suction mouth of each treatment device, and each discharge mouth of the main filtration circuit is distinct from each discharge mouth of each treatment device,
- le dispositif de pompage principal du circuit de filtration principal est distinct du dispositif de pompage de chaque dispositif de traitement,  the main pumping device of the main filtration circuit is distinct from the pumping device of each treatment device,
- l'unité de filtration principale du circuit de filtration principal est distincte de l'unité de traitement de chaque dispositif de traitement.  the main filtration unit of the main filtration circuit is distinct from the treatment unit of each treatment device.
Il s'agit donc d'un bassin, notamment d'un bassin de piscine, déjà équipé d'un circuit hydraulique de traitement, dit circuit de filtration principal, assurant généralement au moins une filtration de l'eau, et auquel on ajoute un second dispositif de traitement conforme à l'invention, qui est totalement indépendant du circuit de filtration principal car il comporte son propre circuit hydraulique, ses propres bouches d'aspiration et de refoulement, et son(ses) propre(s) unité(s) de traitement (par exemple de chauffage) de l'eau.  It is therefore a pool, in particular a swimming pool, already equipped with a hydraulic treatment circuit, said main filtration circuit, generally ensuring at least one filtration of water, and to which is added a second treatment device according to the invention, which is totally independent of the main filtration circuit because it comprises its own hydraulic circuit, its own suction and discharge mouths, and its own unit (s) treatment (eg heating) water.
Ainsi, un dispositif de traitement selon l'invention permet d'améliorer un bassin après la mise en service de ce dernier, qu'il soit ou non déjà équipé d'un circuit de filtration principal de l'eau. Un tel dispositif de traitement permet d'ajouter facilement des fonctionnalités de traitement de l'eau telles qu'un chauffage par une pompe à chaleur ou par des panneaux solaires par exemple.  Thus, a treatment device according to the invention makes it possible to improve a pool after the commissioning of the latter, whether or not it is already equipped with a main water filtration circuit. Such a treatment device makes it easy to add water treatment functions such as heating by a heat pump or by solar panels for example.
L'invention concerne également un bassin caractérisé en combinaison par tout ou partie des caractéristiques mentionnées ci-dessus ou ci-après.  The invention also relates to a pool characterized in combination by all or some of the characteristics mentioned above or below.

FIG. 3 is a diagrammatic representation in longitudinal section of the suction mouth of the device of FIG. 1, in accordance with FIG. - Figure 4 is a schematic representation in longitudinal section of the suction mouth of the device of Figure 1, according to Figures 2 and 3.
Un dispositif de traitement d'une eau de bassin selon l'invention dans le mode de réalisation représenté à la figure 1 est un dispositif qui comprend un circuit 1 hydraulique entre une bouche 7 d'aspiration et une bouche 8 de refoulement disposées dans l'eau 3 de la piscine 2. Entre ces bouches d'aspiration de refoulement sont interposés un dispositif 4 de pompage d'eau destiné à générer un débit d'eau dans le circuit 1 hydraulique, et une unité 5 de traitement de l'eau, par exemple une pompe à chaleur. Le dispositif de pompage comprend en particulier une pompe 14 d'eau alimentée électriquement.  A device for treating pond water according to the invention in the embodiment shown in FIG. 1 is a device which comprises a hydraulic circuit 1 between a suction mouth 7 and a discharge mouth 8 arranged in the water 3 of the pool 2. Between these discharge suction mouths are interposed a device 4 for pumping water intended to generate a flow of water in the hydraulic circuit 1, and a unit 5 for treating the water, for example a heat pump. The pumping device comprises in particular an electrically powered water pump 14.
Le dispositif 4 de pompage est adapté pour pouvoir, lorsqu'il est alimenté électriquement et que le circuit est amorcé en eau, créer une circulation d'eau de la piscine depuis la bouche d'aspiration, vers la bouche de refoulement. On définit les termes « amont » et « aval » dans le circuit 1 hydraulique par rapport à ce sens de circulation de l'eau.  The pumping device 4 is adapted to be able, when it is electrically powered and that the circuit is primed with water, to create a flow of water from the pool from the suction mouth to the discharge mouth. The terms "upstream" and "downstream" are defined in the hydraulic circuit 1 with respect to this direction of water circulation.
Les bouches 7, 8 d'aspiration et de refoulement sont disposées dans l'eau du bassin. La bouche d'aspiration est avantageusement recouverte d'une grille 15 afin d'éviter l'aspiration de corps immergés pouvant endommager et/ou encrasser le circuit 1 hydraulique et ses éléments actifs (pompe, pompe à chaleur, etc.).  The mouths 7, 8 for suction and discharge are arranged in the water basin. The suction mouth is advantageously covered with a grid 15 in order to avoid the suction of submerged bodies that can damage and / or foul the hydraulic circuit 1 and its active elements (pump, heat pump, etc.).
Une conduite, dite conduite 12 amont, du circuit 1 hydraulique relie la bouche 7 d'aspiration au dispositif 4 de pompage. La conduite 12 amont est représentée en arraché sur la figure 1 afin de pouvoir visualiser l'eau et l'air qu'elle contient.  A pipe, called the upstream pipe 12, of the hydraulic circuit 1 connects the suction port 7 to the pumping device 4. The upstream pipe 12 is shown broken away in FIG. 1 in order to be able to visualize the water and the air that it contains.
La conduite 12 amont présente un raccord 10 d'amorçage adapté pour pouvoir être raccordé hydrauliquement à une source 1 1 d'alimentation en eau ne faisant pas partie de l'invention. En particulier ledit raccord 10 d'amorçage présente au moins une extrémité adaptée pour être raccordée à une source d'alimentation en eau. Par exemple, le raccord d'amorçage peut être adapté pour être raccordé à un robinet courant d'une maison d'habitation, par exemple dont le filetage répond à une norme courante de robinetterie. Avantageusement, dans le mode de réalisation représenté aux figures 1 à 4, le raccord d'amorçage 10 est un raccord d'amorçage à connexion rapide avec une prise femelle à clipser. The upstream pipe 12 has a starting connection 10 adapted to be hydraulically connected to a source 1 January water supply not part of the invention. In particular, said priming connector has at least one end adapted to be connected to a source of water supply. For example, the priming connector may be adapted to be connected to a running tap of a dwelling house, for example, whose thread meets a current standard of faucet. Advantageously, in the In the embodiment shown in FIGS. 1 to 4, the priming connector 10 is a quick-connect priming connector with a female plug-in socket.
Avantageusement, comme représenté à la figure 1, le raccord 10 d'amorçage est relié à une source 1 1 d'alimentation en eau sous pression (par exemple reliée à un château d'eau par un réseau de distribution de l'eau potable). L'eau fournie par cette source 1 1 d'alimentation est avantageusement à une pression très supérieure à la pression d'eau régnant au niveau des bouches 7, 8 d'aspiration et de refoulement.  Advantageously, as shown in FIG. 1, the priming connection 10 is connected to a source 1 1 for supplying water under pressure (for example connected to a water tower by a drinking water distribution network). . The water supplied by this source 1 1 feed is advantageously at a pressure much higher than the water pressure prevailing at the mouths 7, 8 suction and discharge.
Ainsi, lorsqu'un robinet (ou une vanne) de la source 11 d'alimentation en eau est ouvert(e), l'eau se répand dans le circuit hydraulique et en particulier dans la conduite 12 amont, en amont et en aval du raccord 10 d'amorçage. Par conséquent, comme représenté à la figure 1, l'eau injectée par le raccord d'amorçage dans le circuit hydraulique forme un front d'eau amont 16 et un front d'eau aval 17 qui repoussent l'air se trouvant dans le circuit hydraulique.  Thus, when a valve (or a valve) of the water supply source 11 is open, the water is spread in the hydraulic circuit and in particular in the upstream pipe 12, upstream and downstream of the boot connection 10. Therefore, as shown in FIG. 1, the water injected by the priming fitting into the hydraulic circuit forms an upstream water front 16 and a downstream water front 17 which push back the air in the circuit. hydraulic.
En particulier, le front d'eau amont 16 et le front d'eau aval In particular, the upstream waterfront 16 and the downstream waterfront
17 repoussent l'air situé dans le circuit hydraulique respectivement en amont et en aval du raccord 10 d'amorçage, de sorte que l'air du circuit hydraulique est respectivement rejeté par la bouche 7 d'aspiration et par la bouche 8 de refoulement. 17 repel the air located in the hydraulic circuit respectively upstream and downstream of the ignition connection 10, so that the air of the hydraulic circuit is respectively rejected by the suction mouth 7 and the discharge mouth 8.
La bouche d'aspiration est équipée d'un clapet 6 représenté sur les figures 2 à 4.  The suction mouth is equipped with a valve 6 shown in Figures 2 to 4.
Comme représenté à la figure 2, lorsque le dispositif selon l'invention est en fonctionnement normal (l'ensemble du circuit hydraulique est plein d'eau et le dispositif 4 de pompage au moins est en fonctionnement) le clapet s'escamote en grande partie pour autoriser l'entrée d'eau 3 de piscine 2 par la bouche 7 d'aspiration. En particulier, le clapet autorise le passage d'eau par une section de passage Sa de la bouche d'aspiration.  As shown in FIG. 2, when the device according to the invention is in normal operation (the entire hydraulic circuit is full of water and the at least 4 pumping device is in operation) the valve retracts to a large extent to allow the entry of pool water 3 by the suction mouth 7. In particular, the valve allows the passage of water through a passage section Sa of the suction mouth.
A cet effet, le clapet est avantageusement souple et/ou articulé au moins dans le sens d'une aspiration d'eau. En particulier, le clapet est avantageusement en éthylène-propylène-diène monomère (EPDM). Il est donc souple et est fixé en un point 18 de fixation à la bouche d'aspiration. Le clapet 6 est fixé au point 18 de fixation de la conduite de la bouche 7 d'aspiration, et il est déformable vers l'aval de la bouche d'aspiration pour laisser un passage à l'eau 3 du bassin 2 aspirée vers le circuit hydraulique grâce à l'aspiration créée par la pompe 14 du dispositif 4 de pompage. For this purpose, the valve is advantageously flexible and / or articulated at least in the sense of a suction of water. In particular, the valve is advantageously ethylene-propylene-diene monomer (EPDM). It is therefore flexible and is fixed at a point 18 of attachment to the suction mouth. The valve 6 is fixed at point 18 for fixing the pipe of the suction mouth 7, and it is deformable downstream of the suction mouth to allow a passage to the water 3 of the basin 2 sucked towards the hydraulic circuit through the suction created by the pump 14 of the device 4 pumping.
Au contraire, si de l'eau circule dans le sens inverse dans le circuit 1 hydraulique, comme représenté à la figure 4, c'est-à-dire dans un sens de refoulement de l'eau par la bouche 7 d'aspiration, le clapet ferme la section de passage Sa de la bouche d'aspiration pour minimiser le flux d'eau rejetée. Le clapet 6 vient en butée sur un épaulement 19 de la bouche d'aspiration dans le sens amont par rapport à la bouche d'aspiration, de sorte qu'il forme une paroi s 'opposant à la sortie de fluide par la bouche d'aspiration.  On the other hand, if water circulates in the opposite direction in the hydraulic circuit 1, as represented in FIG. 4, that is to say in a direction of discharge of the water by the suction mouth 7, the valve closes the passage section Sa of the suction mouth to minimize the flow of rejected water. The valve 6 abuts on a shoulder 19 of the suction mouth in the upstream direction relative to the suction mouth, so that it forms a wall opposing the fluid outlet through the mouth of the aspiration.
Cependant, avantageusement et selon l'invention, le clapet 6 présente un orifice 9 de reflux de section de passage Sr, qui permet au front d'eau amont 16 - lorsqu'il se répand dans la conduite amont - de rejeter l'air se trouvant entre lui et la bouche d'aspiration. En effet, si le clapet était parfaitement hermétique, l'injection d'eau par le raccord 10 d'amorçage créerait une surpression dans la portion en amont de la conduite 12 amont, et l'air s'y trouvant ne pourrait pas refluer par la bouche d'aspiration. Cet air piégé entre le raccord d'amorçage et la bouche d'aspiration aurait pour conséquence de désamorcer la pompe 14 peu de temps après sa mise en marche.  However, advantageously and according to the invention, the valve 6 has a passage orifice 9 of flow section Sr, which allows the upstream water front 16 - when it spreads in the upstream pipe - to reject the air itself. lying between him and the mouth of aspiration. Indeed, if the valve was perfectly hermetic, the injection of water by the priming connection 10 would create an overpressure in the upstream portion of the upstream pipe 12, and the air therein could not reflect by the suction mouth. This air entrapped between the priming connection and the suction mouth would have the consequence of defusing the pump 14 shortly after it is started.
Ainsi, à la figure 3 le déplacement de l'air dans la conduite amont, repoussé par le front d'eau amont 16 est représenté. L'air étant un fluide de faible viscosité, il est facilement rejeté par un orifice 9 de reflux de section de passage Sr inférieure à la section de passage Sa.  Thus, in Figure 3 the displacement of the air in the upstream pipe, pushed by the upstream water front 16 is shown. As the air is a fluid of low viscosity, it is easily rejected by a reflux orifice 9 of passage section Sr which is smaller than the passage section Sa.
Dès lors que le front d'eau amont 16 rejoint le clapet 6, le débit d'eau s'écoulant par l'orifice 9 de reflux est réduit car l'eau est plus visqueuse que l'air et s'écoule moins facilement par la section de passage Sr réduite. Ainsi, une surpression se forme au niveau du clapet qui limite l'écoulement d'eau dans cette portion de la conduite dès lors qu'elle est emplie d'eau.  As soon as the upstream water front 16 meets the valve 6, the flow of water flowing through the orifice 9 of reflux is reduced because the water is more viscous than the air and flows less easily through the cross section Sr reduced. Thus, an overpressure is formed at the valve which limits the flow of water in this portion of the pipe when it is filled with water.
En plus de limiter la perte d'eau d'amorçage dans le bassin, le clapet permet le remplissage du reste du circuit hydraulique dès lors que la portion amont de la conduite 12 amont est emplie d'eau. En effet, la surpression se formant entre l'intérieur et l'extérieur du circuit hydraulique au niveau dudit clapet 6 force l'eau injectée par le raccord d'amorçage à progresser en aval du circuit hydraulique : c'est le front d'eau aval 17 qui repousse l'air du circuit hydraulique en aval du raccord d'amorçage, l'air étant évacué par la bouche 8 de refoulement. In addition to limiting the loss of priming water in the basin, the valve allows the filling of the rest of the hydraulic circuit when the portion upstream of the upstream pipe 12 is filled with water. Indeed, the overpressure formed between the inside and the outside of the hydraulic circuit at said valve 6 forces the water injected by the priming connector to progress downstream of the hydraulic circuit: it is the water front downstream 17 which pushes the air of the hydraulic circuit downstream of the priming connection, the air being discharged through the discharge mouth 8.
Un dispositif conforme à l'invention pourrait aussi comporter un détecteur de variation de la pression ou du débit dans la conduite amont permettant de connaître l'instant à partir duquel la portion amont de la conduite amont est remplie d'eau en détectant la surpression (la diminution de débit) brutale s'y formant au moment où le front d'eau amont 16 rejoint le clapet.  A device according to the invention could also comprise a pressure variation detector or flow in the upstream pipe to know the time from which the upstream portion of the upstream pipe is filled with water by detecting the overpressure ( the brutal flow rate reduction occurring there at the moment when the upstream water front 16 joins the valve.
Ainsi l'orifice 9 de reflux permet l'évacuation de l'air se trouvant dans la conduite 12 amont et minimise la perte d'eau dans le sens d'un refoulement par la bouche d'aspiration.  Thus the reflux port 9 allows the evacuation of the air in the upstream pipe 12 and minimizes the loss of water in the direction of a discharge by the suction port.
Sa combinaison avec un raccord d'amorçage disposé sur la conduite amont permet de proposer un remplissage simple de la conduite amont.  Its combination with a priming connection disposed on the upstream pipe makes it possible to provide a simple filling of the upstream pipe.
Ce remplissage d'eau de la conduite amont est nécessaire au bon fonctionnement du dispositif de pompage dès sa mise en route, notamment afin d'éviter toute cavitation de la pompe 14. C'est pourquoi, avantageusement dans un procédé selon l'invention un utilisateur doit aussi veiller à ce qu'une portion aval de la conduite amont (située entre le raccord 10 d'amorçage et la pompe 14) soit aussi remplie d'eau au moment de mettre le dispositif de pompage en marche.  This water filling of the upstream pipe is necessary for the proper operation of the pumping device as soon as it is started, in particular in order to prevent any cavitation of the pump 14. This is why, advantageously, in a process according to the invention a The user must also ensure that a downstream portion of the upstream pipe (located between the priming connection and the pump 14) is also filled with water when the pumping device is turned on.
Cette portion aval de la conduite 12 amont est remplie d'eau par un front d'eau aval 17 qui rejette l'air qui s'y trouve par la bouche de refoulement qui n'est équipée d'aucun clapet, ni dans un sens, ni dans l'autre.  This downstream portion of the upstream pipe 12 is filled with water by a downstream water front 17 which rejects the air that is there through the discharge mouth which is not equipped with any valve, nor in a sense neither in the other.
Avantageusement la conduite du raccord 10 d'amorçage est équipée d'une vanne 20 pour pouvoir fermer le circuit 1 hydraulique lorsque le dispositif selon l'invention est en fonctionnement. Avantageusement, la vanne 20 est ouverte par l'utilisateur pour amorcer le circuit hydraulique et fermée par l'utilisateur dès que le circuit hydraulique est suffisamment amorcé.  Advantageously, the pipe 10 of the priming is equipped with a valve 20 to be able to close the hydraulic circuit 1 when the device according to the invention is in operation. Advantageously, the valve 20 is opened by the user to prime the hydraulic circuit and closed by the user as soon as the hydraulic circuit is sufficiently primed.
En outre, un dispositif selon l'invention comporte aussi une bouche 13 de remplissage manuel afin de proposer un moyen alternatif de remplissage de la conduite amont. Ainsi un utilisateur peut amorcer manuellement le circuit hydraulique en ajoutant de l'eau par la bouche 13 de remplissage manuel. In addition, a device according to the invention also comprises a mouth 13 for manual filling in order to propose an alternative means of filling the upstream pipe. Thus a user can manually prime the hydraulic circuit by adding water through the manual filling mouth 13.
Aussi, la bouche 13 de remplissage manuel est avantageusement réalisée dans le boîtier du dispositif de pompage selon l'invention de sorte à s'assurer que :  Also, the manual filling mouth 13 is advantageously made in the casing of the pumping device according to the invention so as to ensure that:
- au moins la portion de circuit hydraulique située à proximité de la pompe 14 sera amorcée au moment de la mise en marche du dispositif de pompage,  at least the hydraulic circuit portion located near the pump 14 will be primed at the time of starting of the pumping device,
- la bouche 13 de remplissage manuel est orientée vers le haut pour : the manual filling mouth 13 is oriented upwards for:
• permettre à l'utilisateur de l'alimenter facilement sans devoir la tenir, • allow the user to easily feed it without having to hold it,
• créer une surpression de l'eau apportée par cette bouche par rapport au reste du circuit grâce à la colonne d'eau entre l'ouverture haute de la bouche, et son ouverture sur le circuit hydraulique.  • create an overpressure of the water brought by this mouth compared to the rest of the circuit thanks to the water column between the upper opening of the mouth, and its opening on the hydraulic circuit.
En particulier la hauteur de la bouche 13 de remplissage manuel est choisie adaptée pour que la surpression créée soit supérieure à la pression d'eau régnant au niveau des bouches 7, 8 d'aspiration et de refoulement.  In particular, the height of the manual filling mouth 13 is chosen so that the overpressure created is greater than the water pressure prevailing at the mouths 7, 8 of suction and discharge.
Avantageusement la bouche 13 de remplissage manuel présente une forme d'entonnoir et forme une colonne d'eau débouchant dans le circuit 1 hydraulique. Ainsi, la bouche 13 de remplissage manuel présente avantageusement une colonne d'eau d'environ 50 cm.  Advantageously, the manual filling mouth 13 has a funnel shape and forms a water column opening into the hydraulic circuit 1. Thus, the manual filling mouth 13 advantageously has a water column of about 50 cm.
Avantageusement, un dispositif selon l'invention tel que représenté aux figures 1 à 4 comprend une pompe 14 adaptée pour créer un débit nominal d'environ 2000 L/heure et un circuit 1 hydraulique (en particulier la conduite amont) présente une section de passage d'environ 6 cm2.  Advantageously, a device according to the invention as represented in FIGS. 1 to 4 comprises a pump 14 adapted to create a nominal flow rate of approximately 2000 L / hour and a hydraulic circuit 1 (in particular the upstream pipe) has a passage section. about 6 cm2.
La bouche 7 d'aspiration est sensiblement circulaire et présente une section de passage Sa d'environ 80 cm2. De même, le clapet 6 présente une surface d'environ 80 cm2 pour pouvoir occulter la section de passage Sa de la bouche d'aspiration tout en présentant un orifice 9 de reflux présentant une section de passage Sr d'environ 0,8 cm2.  The suction mouth 7 is substantially circular and has a passage section Sa of about 80 cm 2. Similarly, the valve 6 has an area of about 80 cm2 to conceal the passage section Sa of the suction mouth while having a reflux port 9 having a passage section Sr of about 0.8 cm2.
L'invention peut faire l'objet de nombreuses autres variantes de réalisation non représentées. Ainsi, plusieurs raccords d'amorçage peuvent être prévus pour remplir plus rapidement l'ensemble du circuit. The invention can be the subject of many other embodiments not shown. Thus, several priming connections can be provided to fill the entire circuit faster.
Avantageusement, la bouche d'aspiration et la bouche de refoulement peuvent être disposées à proximité l'une de l'autre. En particulier elles peuvent être formées dans une seule et même pièce plongeant dans l'eau à partir du bord du bassin.  Advantageously, the suction mouth and the discharge mouth can be arranged close to each other. In particular they can be formed in one and the same piece plunging into the water from the edge of the basin.
L'invention peut avantageusement être mise en œuvre pour tous types de dispositif de traitement de l'eau. Elle est particulièrement avantageuse pour des dispositifs ajoutés à un bassin après sa construction, et en tout cas disposés à l'extérieur du bassin.  The invention may advantageously be implemented for all types of water treatment device. It is particularly advantageous for devices added to a pool after its construction, and in any case arranged outside the basin.
L'invention peut avantageusement être un kit comportant un raccord d'amorçage à monter sur le circuit hydraulique, et une bouche d'aspiration dotée d'un clapet à orifice de reflux pouvant être montée sur une bouche d'aspiration existante.  The invention may advantageously be a kit comprising a priming connection to be mounted on the hydraulic circuit, and a suction mouth with a reflux port valve that can be mounted on an existing suction mouth.
En outre, rien n'empêche de prévoir un clapet rigide, articulé par une liaison de type pivot en un point de la bouche d'aspiration pour pouvoir s'ouvrir vers l'aval et venant en butée contre un épaulement ou une butée de la bouche d'aspiration du côté amont. De nombreux autres modes de réalisation d'un clapet peuvent être envisagés avec une fonction identique.  In addition, nothing prevents to provide a rigid valve, articulated by a pivot type connection at a point of the suction mouth to open downstream and abutting against a shoulder or a stop of the suction port on the upstream side. Many other embodiments of a valve can be envisaged with an identical function.
Rien n'empêche non plus de prévoir d'autres moyens de restriction de la section de passage de la bouche d'aspiration dans le sens d'un refoulement : par exemple un obturateur dynamique commandé, etc.  Nothing also prevents other means of restricting the passage section of the suction mouth in the direction of a discharge: for example a controlled dynamic shutter, etc..
