Description

L'invention porte sur un bloc de filtration pour piscine muni d'un système de mesure d'un niveau de colmatage et/ou de détection d'un état de colmatage d'un filtre.The invention relates to a filtration unit for a swimming pool provided with a system for measuring a level of clogging and / or for detecting a state of clogging of a filter.

On connaît des blocs de filtration comportant une cuve ayant une ouverture débouchant dans un volume d'eau de la piscine et une ouverture d'accès destinée à être située au niveau du sol autour de la piscine. Au moins un filtre est disposé à l'intérieur de la cuve. La cuve comporte du côté de son extrémité basse un premier conduit dans lequel circule un flux d'eau primaire. Ce conduit est relié à une entrée d'une pompe, laquelle présente une sortie connectée à une entrée d'injection d'un multiplicateur de débit, notamment de type Venturi. En outre, au moins un deuxième conduit dans lequel circule un flux d'eau secondaire est relié à une entrée d'aspiration du multiplicateur de débit qui génère un courant d'eau à l'intérieur du bassin de la piscine.Filtration blocks are known comprising a tank having an opening opening into a volume of water in the swimming pool and an access opening intended to be located at ground level around the swimming pool. At least one filter is arranged inside the tank. The tank comprises on the side of its lower end a first conduit in which circulates a flow of primary water. This duct is connected to an inlet of a pump, which has an outlet connected to an injection inlet of a flow multiplier, in particular of the Venturi type. In addition, at least a second duct in which a secondary water flow circulates is connected to a suction inlet of the flow multiplier which generates a flow of water inside the basin of the swimming pool.

Afin de détecter un colmatage du filtre par des salissures, le document FR2979656 enseigne d'utiliser un pressostat implanté au niveau du multiplicateur de débit. Toutefois, un tel capteur présente un coût de revient élevé et ne permet pas de détecter un écart de pression suffisamment significatif entre un filtre neuf et un filtre colmaté. En effet, la demanderesse a observé que si un tel capteur de pression était efficace pour détecter l'encrassement d'un filtre à sable, il n'était pas possible de l'utiliser pour détecter le colmatage du filtre en matériau tissé, dans la mesure où l'enceinte du bloc de filtration n'est pas correctement fermée et ne permet donc pas d'observer des variations de pression représentatives d'un colmatage de filtre.In order to detect a clogging of the filter by dirt, the document FR2979656 teaches the use of a pressure switch installed at the flow rate multiplier. However, such a sensor has a high cost price and does not make it possible to detect a sufficiently significant pressure difference between a new filter and a clogged filter. Indeed, the Applicant has observed that if such a pressure sensor was effective in detecting the clogging of a sand filter, it was not possible to use it to detect the clogging of the filter made of woven material, in the insofar as the enclosure of the filtration unit is not properly closed and therefore does not make it possible to observe pressure variations representative of a clogging of the filter.

L'invention vise à remédier à cet inconvénient en partant du constat que lorsque la cartouche est colmatée, la quantité d'eau filtrée diminue. L'invention propose donc de mesurer le débit d'eau à l'aide d'un capteur correspondant moins onéreux qu'un capteur de pression pour en déduire le niveau de colmatage du filtre. L'écart de débit entre un filtre non colmaté et un filtre colmaté est suffisamment significatif pour permettre la détection du colmatage du filtre.The invention aims to remedy this drawback by starting from the observation that when the cartridge is clogged, the quantity of filtered water decreases. The invention therefore proposes to measure the flow of water using a corresponding sensor less expensive than a pressure sensor in order to deduce therefrom the level of clogging of the filter. The gap The flow rate between an unclogged filter and a clogged filter is significant enough to allow detection of filter clogging.

The invention will be better understood on reading the description which follows and on examining the accompanying figures. These figures are given only by way of illustration but in no way limit the invention.

  • [ Fig. 2 ] The figure 2 is a rear perspective view of the filtration unit according to the invention incorporating a system for measuring a level of clogging and / or a state of clogging of a filter.

Les éléments identiques, similaires ou analogues conservent la même référence d'une figure à l'autre.Identical, similar or analogous elements keep the same reference from one figure to another.

Les figures 1 et 2 montrent un bloc de filtration 10 pour piscine comportant une cuve 11 ayant une ouverture 12 débouchant dans un volume du bassin de piscine, via un conduit récupérateur 13, et une ouverture d'accès 15 destinée à être située au niveau du sol autour de la piscine. L'ouverture d'accès 15 est destinée à être obturée par une trappe amovible (non représentée).The figures 1 and 2 show a filtration unit 10 for a swimming pool comprising a tank 11 having an opening 12 opening into a volume of the swimming pool basin, via a collecting duct 13, and an access opening 15 intended to be located at ground level around the swimming pool . The access opening 15 is intended to be closed by a removable hatch (not shown).

Au moins un filtre est disposé à l'intérieur de la cuve 11. Avantageusement, un premier filtre 16.1 assure une filtration grossière laissant passer les particules de dimension inférieure à une fraction de millimètre sur un principe de filtre écran. Par exemple, ce premier filtre 16.1 est constitué d'un panier avantageusement formé d'une toile à orifices de 0.1 à 0.5mm, par exemple 0.3mm, moulée entre des nervures de matière plastique injectée. En outre, un deuxième filtre 16.2 assurant une filtration fine comprend un filtre cylindrique constitué d'une nappe d'un matériau non tissé plissé en accordéon. La nappe est maintenue entre deux flasques circulaires et entourée d'un matériau non tissé extérieur. La cuve 11 pourra être munie d'un dispositif de trop-plein 14.At least one filter is placed inside the tank 11. Advantageously, a first filter 16.1 provides coarse filtration allowing particles of size less than a fraction of a millimeter to pass on a screen filter principle. For example, this first filter 16.1 consists of a basket advantageously formed of a fabric with orifices of 0.1 to 0.5 mm, for example 0.3 mm, molded between ribs of injected plastic material. In addition, a second filter 16.2 providing fine filtration comprises a cylindrical filter made of a web of an accordion-pleated nonwoven material. The web is held between two circular flanges and surrounded by an outer nonwoven material. The tank 11 may be fitted with an overflow device 14.

Un premier conduit 17 issu de la cuve 11 dans lequel circule un flux d'eau primaire est relié à une entrée d'une pompe 18, laquelle présente une sortie connectée à une entrée d'injection 19 d'un multiplicateur de débit 21. Un deuxième conduit 22 issu de la cuve 11 dans lequel circule un flux d'eau secondaire est relié à une entrée d'aspiration 24 du multiplicateur de débit 21. Le multiplicateur de débit 21, notamment de type Venturi, comporte, de façon connue en soi, un tronçon convergent et un tronçon divergent pour accélérer le flux d'eau généré à sa sortie 25 permettant de créer le courant à l'intérieur du bassin de piscine. La pompe 18 pourra comporter un moteur électrique à vitesse variable, multivitesse, ou vitesse fixe afin de faire varier l'intensité du débit d'eau à l'intérieur du bassin.A first pipe 17 issuing from the tank 11 in which circulates a primary water flow is connected to an inlet of a pump 18, which has an outlet connected to an injection inlet 19 of a flow multiplier 21. A second duct 22 issuing from tank 11 in which a secondary water flow circulates is connected to a suction inlet 24 of the flow rate multiplier 21. The flow rate multiplier 21, in particular of the Venturi type, comprises, in a manner known per se , a converging section and a diverging section to accelerate the flow of water generated at its outlet 25 making it possible to create the current inside the swimming pool basin. The pump 18 may include an electric motor with variable speed, multispeed, or fixed speed in order to vary the intensity of the water flow inside the basin.

Le conduit récupérateur 13 et la sortie 25 du multiplicateur de débit débouchent dans une plaque 26 intégrée dans un muret 27 de la piscine.The recovery duct 13 and the outlet 25 of the flow multiplier open into a plate 26 integrated in a wall 27 of the swimming pool.

En outre, le bloc de filtration 10 comporte un système 28 de mesure d'un niveau de colmatage du filtre et/ou de détection d'un état de colmatage du filtre 16.1, 16.2.In addition, the filtration unit 10 comprises a system 28 for measuring a level of clogging of the filter and / or for detecting a state of clogging of the filter 16.1, 16.2.

Ce système 28 comprend un capteur 29 de mesure de débit ou de vitesse de fluide, un conduit d'aspiration 30.1 connecté au capteur 29 ayant un piquage d'aspiration 31.1 réalisé dans une zone communicante avec de l'eau du bassin, notamment une zone d'aspiration d'eau 33, et un conduit de sortie 30.2 connecté au capteur 29 ayant un piquage de sortie 31.2 réalisé dans une zone de refoulement d'eau 34.This system 28 comprises a sensor 29 for measuring the flow or speed of the fluid, a suction duct 30.1 connected to the sensor 29 having a suction tap 31.1 made in a zone communicating with the water of the basin, in particular a zone water suction 33, and an outlet pipe 30.2 connected to the sensor 29 having an outlet tapping 31.2 made in a water delivery zone 34.

Dans l'exemple représenté sur les figures 1 et 2, le piquage d'aspiration 31.1 est ménagé dans une zone d'aspiration 33 basse du bassin de la piscine. Le piquage d'aspiration 31.1 est ainsi réalisé dans un tuyau 35 traversant de part en part le muret 27 de la piscine. En l'occurrence, ce tuyau 35 est fermé du côté de son extrémité arrière mais il pourrait en variante être connecté au circuit de filtration d'eau.In the example shown on figures 1 and 2 , the suction connection 31.1 is provided in a lower suction zone 33 of the pool basin. The suction connection 31.1 is thus produced in a pipe 35 passing right through the wall 27 of the swimming pool. In this case, this pipe 35 is closed on the side of its rear end but it could alternatively be connected to the water filtration circuit.

Alternativement, le piquage d'aspiration 31.1 est ménagé dans la cuve 11 ou dans un régulateur de niveau d'eau. Ainsi, le piquage d'aspiration 31.1 pourra être réalisé quasiment dans toute zone située autour du bloc de filtration 10 à l'exception de la zone de refoulement 34, du conduit de sortie de la pompe 18 et du conduit d'aspiration 17.Alternatively, the suction tap 31.1 is provided in the tank 11 or in a water level regulator. Thus, the suction connection 31.1 can be carried out almost in any zone located around the filtration unit 10 with the exception of the discharge zone 34, of the outlet pipe of the pump 18 and of the suction pipe 17.

Par ailleurs, le piquage de sortie 31.2 est réalisé dans le multiplicateur de débit 21 constituant la zone de refoulement 34.Furthermore, the outlet tapping 31.2 is made in the flow multiplier 21 constituting the delivery zone 34.

Avantageusement, un piquage 31.1, 31.2 des conduits est réalisé via un connecteur encliquetable. En variante, le piquage 31.1, 31.2 des conduits est effectué par collage, soudage, ou vissage, ou tout autre moyen adapté à l'application.Advantageously, a branching 31.1, 31.2 of the conduits is made via a snap-on connector. As a variant, the tapping 31.1, 31.2 of the conduits is carried out by gluing, welding, or screwing, or any other means suitable for the application.

Par ailleurs, comme cela est illustré sur la figure 2, un module de contrôle 37 permet de déterminer un niveau de colmatage et/ou un état de colmatage du filtre en fonction du débit d'eau mesuré par le capteur 29.Moreover, as illustrated on figure 2 , a control module 37 makes it possible to determine a level of clogging and / or a state of clogging of the filter as a function of the water flow rate measured by the sensor 29.

La détermination du niveau de colmatage pourra être effectuée via l'exploitation d'une cartographie C établissant la correspondance entre un niveau de colmatage, exprimé par exemple en pourcents, et un débit mesuré par le capteur 29.The level of clogging can be determined by using a map C establishing the correspondence between a level of clogging, expressed for example in percent, and a flow rate measured by the sensor 29.

En variante ou en complément, le module de contrôle 37 détermine un état "non colmaté" ou "colmaté" par comparaison du débit mesuré par le capteur 29 avec un seuil. Ainsi, on considère que le filtre est à l'état "non colmaté" lorsque le débit mesuré par le capteur 29 est supérieur au seuil et à l'état "colmaté" lorsque le débit mesuré par le capteur 29 devient inférieur au seuil. Bien entendu, des niveaux de colmatage intermédiaires pourront être détectés à l'aide de seuils intermédiaires.As a variant or in addition, the control module 37 determines an “unclogged” or “clogged” state by comparing the flow rate measured by the sensor 29 with a threshold. Thus, it is considered that the filter is in the “unclogged” state when the flow rate measured by the sensor 29 is greater than the threshold and in the “blocked” state when the flow rate measured by the sensor 29 becomes less than the threshold. Of course, intermediate levels of clogging can be detected using intermediate thresholds.

Le module de contrôle 37 pourra comporter des moyens de communication 40 du niveau de colmatage et/ou de l'état de colmatage du filtre à un dispositif de surveillance et/ou un dispositif portable. Les moyens de communication 40 pourront être de type sans fil ou filaire.The control module 37 may include means 40 for communicating the level of clogging and / or the state of clogging of the filter to a monitoring device and / or a portable device. The means of communication 40 may be of the wireless or wired type.

Bien entendu, la description qui précède a été donnée à titre d'exemple uniquement et ne limite pas le domaine de l'invention dont on ne sortirait pas en remplaçant les différents éléments par tous autres équivalents.Of course, the foregoing description has been given by way of example only and does not limit the field of the invention, from which one would not depart by replacing the various elements with all other equivalents.
