Description

La présente invention vise un appareil automatique pour maintenir un pH à une valeur déterminée notamment dans l'eau d'une piscine. The present invention relates to an automatic device for maintaining a pH at a determined value in particular in the water of a swimming pool.

L'invention vise plus particulièrement des piscines comprenant une installation de filtration de l'eau et une installation de stérilisation électrochimique de celle-ci, comprenant une électrode cuivre argent. The invention relates more particularly to swimming pools comprising a water filtration installation and an electrochemical sterilization installation thereof, comprising a silver copper electrode.

On a constaté qu'avec ce type d'installation de stérilisation de l'eau, il était important que le pH soit maintenu à une valeur sensiblement neutre ce qui oblige à effectuer des mesures répétées et à modifier celuici en ajoutant, soit un acide, soit une base. It has been found that with this type of water sterilization installation, it is important that the pH is maintained at a substantially neutral value, which requires repeated measurements and modification thereof by adding either an acid, be a base.

L'invention a pour objet, une installation qui permet automatiquement de maintenir le pH à une valeur déterminée. The subject of the invention is an installation which automatically makes it possible to maintain the pH at a determined value.

L'appareil, selon l'invention est destiné à des piscines comprenant une installation de filtration avec un circuit comprenant une pompe aspirant l'eau de la piscine, la refoulant dans un filtre et un tuyau acheminant l'eau filtrée à la piscine et est caractérisé en ce qu'il comprend une sonde insérée dans ledit tuyau et reliée à un pH mètre comportant des moyens pour déterminer deux seuils de pH entre lesquels l'eau de la piscine doit être maintenue, deux pompes doseuses dont l'aspiration est reliée l'une à un bac contenant une solution basique et l'autre à un bac contenant une solution acide, tandis que le refoulement est relié au circuit d'eau de la piscine, et des moyens pour commander sélectivement les pompes lorsque le pH est différent des seuils déterminés et ainsi envoyer une dose de solution correspondante dans le circuit d'eau. The device according to the invention is intended for swimming pools comprising a filtration installation with a circuit comprising a pump sucking water from the swimming pool, discharging it into a filter and a pipe conveying the filtered water to the swimming pool and is characterized in that it comprises a probe inserted in said pipe and connected to a pH meter comprising means for determining two pH thresholds between which the water in the swimming pool must be maintained, two metering pumps whose suction is connected l '' one to a tank containing a basic solution and the other to a tank containing an acid solution, while the discharge is connected to the swimming pool water circuit, and means for selectively controlling the pumps when the pH is different from the determined thresholds and thus send a dose of corresponding solution into the water circuit.

De préférence, le pH mètre comprend un dispositif d'affichage du pH. Preferably, the pH meter includes a device for displaying the pH.

Suivant une caractéristique constructive, le tuyau comprend une dérivation sur laquelle est insérée la sonde de mesure du pH avec des vannes pour mettre hors cicuit cette dérivation. According to a constructive characteristic, the pipe comprises a bypass on which is inserted the pH measurement probe with valves to put off this bypass.

Enfin, la piscine est du type comprenant une installation de stérilisation électrochimique.  Finally, the swimming pool is of the type comprising an electrochemical sterilization installation.

L'invention va maintenant être décrite avec plus de détails en se référant à un mode de réalisation particulier et représenté à la figure unique qui est une vue schématique d'une installation, selon l'invention. The invention will now be described in more detail with reference to a particular embodiment and shown in the single figure which is a schematic view of an installation according to the invention.

A la figure, la référence 1 désigne un tuyau qui par une extrémité relie la piscine à l'aspiration d'une pompe dont le refoulement débouche dans un filtre, ledit tuyau acheminant l'eau ensuite vers un chauffage éventuel et ramenant celle-ci à la piscine. Un tel circuit fermé est classique. In the figure, reference 1 designates a pipe which at one end connects the swimming pool to the suction of a pump, the discharge of which opens into a filter, said pipe then conveying the water to possible heating and bringing it back to the swimming pool. Such a closed circuit is conventional.

L'installation, selon l'invention, prévoit un appareil 2 relié à un réseau de distribution électrique et qui alimente par des conducteurs 3 deux électrodes 4 formées d'un complexe cuivre argent et qui sont périodiquement mises sous tension. L'appareil 2 comporte un cadran 6 qui permet de vérifier la mise sous tension desdites électrodes. Les électrodes 4 sont logées dans une petite cuve 7 montée sur le tuyau 1. The installation, according to the invention, provides an apparatus 2 connected to an electrical distribution network and which supplies by conductors 3 two electrodes 4 formed from a copper silver complex and which are periodically energized. The apparatus 2 comprises a dial 6 which makes it possible to check the energization of said electrodes. The electrodes 4 are housed in a small tank 7 mounted on the pipe 1.

Sur le tuyau 1 est monté un tube de dérivation 8 pourvu de deux vannes 9 et 10, une vanne 11 étant prévue sur ledit tuyau 1 entre les deux branches de la dérivation. On the pipe 1 is mounted a bypass tube 8 provided with two valves 9 and 10, a valve 11 being provided on said pipe 1 between the two branches of the bypass.

Le tube 8 de la dérivation comporte une cuve 12 dans laquelle plonge une sonde 13 de mesure du pH reliée à un appareil 14 par un conducteur 15. The tube 8 of the bypass comprises a tank 12 into which a probe 13 for measuring the pH is connected, connected to an apparatus 14 by a conductor 15.

L'appareil 14 comprend un dispositif d'afficha- ge 16 du pH et deux dispositifs 17 et 18 d'affichage des seuils entre lesquels le pH doit être maintenu. The apparatus 14 comprises a device 16 for displaying the pH and two devices 17 and 18 for displaying the thresholds between which the pH must be maintained.

Bien entendu, l'appareil 14 qui constitue un pH mètre est agencé pour permettre un calibrage au moment de la mise en route de l'installation et il est prévu un interrupteur général 20 et deux boutons de commande 19 de modification de seuils. Of course, the apparatus 14 which constitutes a pH meter is arranged to allow calibration when the installation is started up and there is provided a general switch 20 and two control buttons 19 for modifying thresholds.

I1 est prévu une pompe 21 dont l'aspiration est reliée par un tuyau 23 à un bac 22 contenant une solution basique et dont le refoulement est relié par un tuyau 24 au tuyau 1.  A pump 21 is provided, the suction of which is connected by a pipe 23 to a tank 22 containing a basic solution and the discharge of which is connected by a pipe 24 to the pipe 1.

Une seconde pompe 27 est reliée nar un tuyau d'aspi ation 28 à un bac 29 contenant une solution acide, tandis que son refoulement est relié par un tuyau 30 au tuyau 1. A second pump 27 is connected by a suction pipe 28 to a tank 29 containing an acid solution, while its discharge is connected by a pipe 30 to the pipe 1.

Les pompes 21 et 27 sont des pompes doseuses, et chaque pompe 21 et 27 est reliée, par des conducteurs respectivement 32 et 33, au pH mètre 14 qui comporte des circuits de commande pour fermer les circuits respectifs des pompes si l'eau a des valeurs de pH différentes des seuils atfichés. The pumps 21 and 27 are metering pumps, and each pump 21 and 27 is connected, by conductors respectively 32 and 33, to the pH meter 14 which has control circuits to close the respective circuits of the pumps if the water has pH values different from the displayed thresholds.

Ainsi, si la valeur du pH mesurée par la sonde 12 et transmise au FE mètre lo descend au-dessous du seuil prévu, ledit pH mètre 14 commandera la fermeture du circuit de la pompe 27 qui aspirera une dose de la solution du bac 29 et la refoulera par le tuyau 30 dans le tuyau 1. Thus, if the pH value measured by the probe 12 and transmitted to the FE meter lo drops below the prescribed threshold, said pH meter 14 will close the circuit of the pump 27 which will draw a dose of the solution from the tank 29 and will push it back through pipe 30 into pipe 1.

Si au contraire, le pH dépasse le seuil le circuit de la pompe 21 sera fermé et une dose de la solution basique du bac 22 sera aspirée et refoulée dans le tuyau 1. If, on the contrary, the pH exceeds the threshold, the circuit of the pump 21 will be closed and a dose of the basic solution of the tank 22 will be sucked up and discharged into the pipe 1.

Bien entendu, l'invention n'est pas limitée au mode de réalisaticn qui vient d'être décrit et représenté. On pourra y apporter de nombreuses modifications de détail sans sortir pour cela du cadre de l'invention.  Of course, the invention is not limited to the embodiment which has just been described and shown. Many modifications of detail can be made without departing from the scope of the invention.
