Abstract

The invention relates to water purifier devices starting with a membrane filter with tangential filtration of the kind comprising a delivery for unfiltered water and two outlets, one reserved for the filtered water and the other reserved for unfiltered water. The invention relates to a device in which the delivery for unfiltered water (1) communicates directly and solely with the chamber (4) which, on the one hand, surrounds the filtering wall of the filter (5) through which part of the water passes to be recovered filtered via the corresponding outlet (2) and which, on the other hand, comprises an opening (6) placing the unfiltered water surrounding the said chamber in direct communication with the corresponding outlet (3) so as to clean the surface of the filtering wall at the same time.

Description

L'invention se rapporte aux dispositifs purificateur d'eau à partir d'un filtre à membrane à filtration tangentielle du genre comportant une arrivée d'eau non-filtrée et deux sorties l'une réservée à l'eau filtrée et l'autre réservée à l'eau non-filtrée. The invention relates to water purifying devices from a membrane filter with tangential filtration of the kind comprising an inlet of unfiltered water and two outlets one reserved for filtered water and the other reserved with unfiltered water.

Les dispositifs connus du genre en question sont de deux types a) celui commercialisé par la société française FITAMM qui comporte une entrée et deux sorties, dont celle correspondant à l'eau non filtrée est en face de entrée, autrement-dit totalement indépendante de la chambre contenant le filtre : une vanne unique permet de passer de la position eau filtrée à la position eau non-filtrée; b) celui commercialisé par la société française ESSER qui comporte une entrée et une sortie, autrement-dit le circuit eau non-filtrée est également totalement indépendant de la chambre contenant le filtre : un bouton poussoir à deux positions permet le passage eau filtrée - eau non filtrée. The known devices of the kind in question are of two types a) that marketed by the French company FITAMM which comprises an inlet and two outlets, of which that corresponding to unfiltered water is opposite the inlet, in other words totally independent of the chamber containing the filter: a single valve makes it possible to pass from the filtered water position to the unfiltered water position; b) that marketed by the French company ESSER which has an inlet and an outlet, in other words the unfiltered water circuit is also completely independent of the chamber containing the filter: a push button with two positions allows the passage of filtered water - water unfiltered.

Ces deux dispositifs présentent deux inconvénients a) il n'est pas possible d'avoir simultanément de l'eau filtrée et de Liteau non-filtrée; #b) pour nettoyer le filtre il faut le démonter : la fréquence de l'intervention étant fonction de la qualité de l'eau chargée utilisée.These two devices have two drawbacks a) it is not possible to have filtered water and unfiltered batten simultaneously; #b) to clean the filter it must be dismantled: the frequency of the intervention being a function of the quality of the charged water used.

L'invention vise à réaliser un dispositif du genre en question dans lequel les inconvénients sus-mentionnés se trouvent supprimés. The invention aims to produce a device of the type in question in which the above-mentioned drawbacks are eliminated.

Il concerne à cet effet un ensemble pour lequel l'arrivée d'eau non-filtrée communique directement et uniquement avec la chambre qui, d'une part, entoure la paroi filtrante du filtre qu'une partie de l'eau traverse pour être récupérée filtrée par la sortie correspondante et qui, d'autre part, comporte une ouverture mettant en communication directe l'eau non-filtrée entourant ladite chambre avec la sortie correspondante de manière à nettoyer en même temps la surface de la paroi filtrante.To this end, it relates to an assembly for which the arrival of unfiltered water communicates directly and only with the chamber which, on the one hand, surrounds the filtering wall of the filter that part of the water passes through to be recovered. filtered by the corresponding outlet and which, on the other hand, comprises an opening putting in direct communication the unfiltered water surrounding said chamber with the corresponding outlet so as to clean at the same time the surface of the filtering wall.

Les caractéristiques et les avantages de l'invention vont apparaitre plus clairement à la lecture de la description détaillée qui suit d'un mode de réalisation préférentiel de l'invention donné à titre d'exemple seulement et représenté au dessin annexé qui est une vue en coupe du dispositif selon l'invention. The characteristics and advantages of the invention will appear more clearly on reading the following detailed description of a preferred embodiment of the invention given by way of example only and shown in the accompanying drawing which is a view in section of the device according to the invention.

Le dispositif représenté comporte un corps (12) possédant une entrée (1) d'arrivée d'eau non-filtrée et deux sorties (2) et (3) d'eau filtrée et d'eau non-filtrée respectivement. The device shown comprises a body (12) having an inlet (1) for unfiltered water inlet and two outlets (2) and (3) for filtered water and unfiltered water respectively.

Il comporte également - une chambre (4) dans laquelle est logé le filtre à membrane (5) à filtration tangentielle de dimensions diamètrales inférieures à celles de la chambre de manière à dégager un volume entourant ledit filtre dans laquelle circule l'eau non-filtrée; - une ouverture (6) mettant en communication directe l'eau non-filtrée entourant ladite chambre avec la sortie (3) correspondante de manière à nettoyer en même temps la surface de la paroi filtrante.It also comprises - a chamber (4) in which is housed the membrane filter (5) with tangential filtration of diametrical dimensions smaller than those of the chamber so as to release a volume surrounding said filter in which the unfiltered water circulates ; - An opening (6) in direct communication with the unfiltered water surrounding said chamber with the corresponding outlet (3) so as to clean the surface of the filtering wall at the same time.

L'arrivée (1) étant en communication directe et unique avec la chambre (4).The arrival (1) being in direct and unique communication with the room (4).

La chambre entourant le filtre est rendue étanche à ces deux extrémités d'une part par un joint torique (9) sur lequel elle vient en appui et d'autre part par le joint plat (10) situé dans le fond du bouchon (11) permettant la sortie du filtre.The chamber surrounding the filter is sealed at these two ends on the one hand by an O-ring (9) on which it bears and on the other hand by the flat seal (10) located in the bottom of the plug (11) allowing the filter to exit.

Les sorties (2) et (3) peuvent comporter des robinets autonomes (7) et (8) permettant de les obturer à volonté.The outlets (2) and (3) may include autonomous valves (7) and (8) allowing them to be closed at will.

Le dispositif peut être vissé directement sur un robinet standard (13): une bague d'étanchéité (14) étant interposée entre (I) et (13).The device can be screwed directly onto a standard tap (13): a sealing ring (14) being interposed between (I) and (13).

Le dispositif peut également être inséré sur le trajet d'une canalisation existante par l'intermèdiaire de son entrée unique (1) et de sa sortie d'eau non-filtrée (3). The device can also be inserted on the path of an existing pipe through its single inlet (1) and its outlet of unfiltered water (3).

Le corps du filtre (5) dépasse légèrement la chambre (4) de manière à comprimer le joint (10) pour assurer une parfaite étanchéité.The filter body (5) slightly exceeds the chamber (4) so as to compress the seal (10) to ensure a perfect seal.

Des brise-jets peuvent être montés sur les sorties (2) et (3).Jet splitters can be mounted on outputs (2) and (3).

Pour accroitre l'efficacité du nettoyage du filtre, on peut envoyer de l'eau chaude dans le dispositif à partir du tuyau d'arrivée (13).To increase the efficiency of the filter cleaning, hot water can be sent into the device from the inlet pipe (13).

Dans la réalisation préférée de l'invention, les entrée-sortie (1) et (3) sont en opposition.In the preferred embodiment of the invention, the input-output (1) and (3) are in opposition.

Bien entendu, l'invention n'est pas limitée au mode de réalisation décrit et représenté pour lequel on pourra prévoir d'autres variantes, utiliser tous types de matériaux et de filtres et l'étendre à d'autres applications sans pour cela sortir du cadre de l'invention.  Of course, the invention is not limited to the embodiment described and shown for which we can provide other variants, use all types of materials and filters and extend it to other applications without departing from the part of the invention.
