Description

La présente invention concerne le domaine des dispositifs de distribution, de dosage et de dilution automatique de produit liquide et plus particulièrement de produit d'entretien à usage professionnel.The present invention relates to the field of devices for dispensing, dosing and automatic dilution of liquid product and more particularly maintenance product for professional use.

Les produits d'entretien, par exemple des produits détergents pour le nettoyage des sols, sont dilués dans de l'eau à des concentrations précises, selon un dosage précis en fonction du volume d'eau, pour être efficaces. Si ce dosage est trop faible, l'efficacité du produit d'entretien est réduite, et si ce dosage est trop fort, une trop grande quantité de produit est utilisé et donc il en résulte une augmentation des couts, une efficacité réduite par exemple à cause d'un encrassement de la surface à nettoyer par le produit d'entretien en lui-même, ainsi qu'un impact environnementale accru. En effet, ces produits d'entretien ont un impact sur l'environnement, notamment du fait de leur production et après leur utilisation du fait du traitement des eaux usées.Cleaning products, for example detergent products for cleaning floors, are diluted in water at precise concentrations, in a precise dosage according to the volume of water, to be effective. If this dosage is too low, the effectiveness of the cleaning product is reduced, and if this dosage is too strong, too much product is used and therefore it results in increased costs, reduced efficiency for example to because of a fouling of the surface to be cleaned by the cleaning product itself, as well as an increased environmental impact. Indeed, these cleaning products have an impact on the environment, particularly because of their production and after their use due to the treatment of wastewater.

Il est donc important de permettre un dosage optimal du produit d'entretien afin de réduire les couts ainsi que de minimiser l'impact environnemental de son utilisation et ce tout en gardant une efficacité optimale dudit produit d'entretien.It is therefore important to allow optimal dosage of the cleaning product to reduce costs and minimize the environmental impact of its use while maintaining optimum efficiency of said cleaning product.

Une solution connue à ce problème est l'utilisation d'un dispositif de distribution automatique qui délivre un dosage constant de produit et ce quelque soit le volume d'eau utilisé. Ce genre de dispositif utilise généralement un injecteur venturi placé dans un circuit d'eau et relié au produit d'entretien. Au moyen d'une buse calibrée, ledit injecteur venturi permet de dispenser et de diluer une dose de produit d'entretien variant en fonction de la quantité d'eau traversant le circuit d'eau, ainsi le dosage final est constant. Il existe des dispositifs relié à plusieurs produits d'entretien, permettant un choix du produit grâce à un sélecteur.A known solution to this problem is the use of an automatic dispensing device that delivers a constant dosage of product regardless of the volume of water used. This kind of device uses typically a venturi injector placed in a water circuit and connected to the cleaning product. By means of a calibrated nozzle, said venturi injector makes it possible to dispense and dilute a dose of maintenance product that varies according to the quantity of water passing through the water circuit, so that the final dosage is constant. There are devices connected to several cleaning products, allowing a choice of product through a selector.

Néanmoins ce genre de dispositif est utilisé à grande échelle et est donc généralement soit directement fixé à un mur près d'une arrivée d'eau, ou bien comme montré par la demande US2005/0051197 , installé sur des chariots qui sont difficilement manoeuvrable et mobile du fait qu'ils transportent à la fois le dispositif en lui même ainsi que les contenants de grande capacité du ou des produits d'entretien. Ainsi, par exemple pour de grandes surfaces à nettoyer, il est nécessaire de revenir continuellement auprès du dispositif pour renouveler le mélange eau/produit ou de changer de mélange eau/produit.Nevertheless this kind of device is used on a large scale and is therefore usually either directly attached to a wall near a water inlet, or as shown by the request US2005 / 0051197 , installed on trolleys that are difficult to maneuver and mobile because they carry both the device itself and the containers of high capacity or maintenance products. Thus, for example for large areas to be cleaned, it is necessary to return continuously to the device to renew the water / product mixture or to change the water / product mixture.

La présente invention a donc comme objectif de résoudre au moins en partie les inconvénients de l'art antérieur et de proposer un dispositif de distribution, de dosage et de dilution automatique de produit liquide optimisé pour un usage simplifié et mobile.The present invention therefore aims to solve at least partly the disadvantages of the prior art and to propose a device for dispensing, dosing and automatic dilution of liquid product optimized for simplified and mobile use.

Ainsi l'invention concerne un dispositif de distribution, de dosage et de dilution automatique dans l'eau d'un produit d'entretien liquide, sélectionné parmi au moins deux produits d'entretien, comprenant :

  • une entrée d'eau et une sortie d'eau, reliées par un circuit d'eau sous pression,

  • a water inlet and a water outlet, connected by a pressurized water circuit,
  • a product selector from said at least two products, each maintenance product being contained in an individual container,
  • a venturi injector located in the pressurized water circuit and connecting said product selector to said pressurized water circuit,
said dispensing device and the containers of said at least two products being contained in a closed receptacle, composed of two half-shells assembled together, and the pressurized water circuit comprising an on-off valve placed upstream of the injector venturi.

Selon un autre aspect de l'invention, la demi-coque, opposée à la demi-coque comportant à sa surface le moyen de manipulation du sélecteur de produit, comporte une trappe permettant l'accès aux contenants desdits au moins deux produits d'entretien.According to another aspect of the invention, the half-shell, opposite the half-shell having on its surface the means for handling the product selector, comprises a hatch allowing access to the containers of said at least two cleaning products. .

Selon un autre aspect de l'invention, le nombre de produit d'entretien est de trois.According to another aspect of the invention, the number of maintenance products is three.

Selon un autre aspect de l'invention, les contenants des trois produits d'entretien sont disposés côtes à côtes au sein du réceptacle.According to another aspect of the invention, the containers of the three cleaning products are arranged side by side within the receptacle.

Selon un autre aspect de l'invention, la contenance des deux contenants latéraux est de un litre et que le contenant central a une contenance de deux litres.According to another aspect of the invention, the capacity of the two side containers is one liter and the central container has a capacity of two liters.

Selon un autre aspect de l'invention, le sélecteur de produit est un sélecteur quatre positions.According to another aspect of the invention, the product selector is a four-position selector.

Selon un autre aspect de l'invention, le réceptacle comporte des rainures permettant l'enroulement et l'accroche d'un tuyau faisant la liaison entre l'arrivée d'eau et l'entrée d'eau.According to another aspect of the invention, the receptacle comprises grooves for winding and hooking a pipe connecting the water inlet and the water inlet.

  • The figure 5 shows a simplified diagram of an example of valve opening means.

Les éléments identiques sur les différentes figures sont représentés avec les mêmes références.The identical elements in the different figures are represented with the same references.

Comme le montre les différentes figures, le dispositif de distribution, de dosage et de dilution automatique 1 comporte un circuit d'eau sous pression 6 contenu dans un réceptacle 8 clos, formé de deux demi-coques 8A et 8B. Le circuit d'eau sous pression 6 fait la liaison entre une entrée d'eau 3, destinée à être reliée à une arrivée d'eau par exemple au moyen d'un tuyau, et une sortie d'eau 4.As shown in the various figures, the dispensing device, dosage and automatic dilution 1 comprises a pressurized water circuit 6 contained in a closed receptacle 8, formed of two half-shells 8A and 8B. The pressurized water circuit 6 makes the connection between a water inlet 3 intended to be connected to a water inlet, for example by means of a pipe, and a water outlet 4.

Les figures 1 et 2 montrent plus en détail l'intérieur du réceptacle 8. Le circuit d'eau sous pression 6 comprend un injecteur venturi 18 relié à au moins deux produits d'entretien 10A, 10B, 10C, permettant une dilution, un mélange et un dosage constant desdits produits d'entretien 10A, 10B, 10C quelque soit la quantité d'eau transitant dans le circuit d'eau sous pression 6.The figures 1 and 2 show more in detail the interior of the receptacle 8. The pressurized water circuit 6 comprises a venturi injector 18 connected to at least two maintenance products 10A, 10B, 10C, permitting constant dilution, mixing and dosing of said maintenance products 10A, 10B, 10C regardless of the quantity of water passing through the pressurized water circuit 6.

La liaison entre lesdits au moins deux produits d'entretien 10A, 10B, 10C et l'injecteur venturi 18 est effectuée par un sélecteur de produit 14. Ledit sélecteur permet de choisir quel produit parmi lesdits au moins deux produits d'entretien 10A, 10B, 10C sera relié à l'injecteur venturi et de fait, mélangé avec l'eau circulant dans le circuit d'eau sous pression 6.The connection between said at least two maintenance products 10A, 10B, 10C and the venturi injector 18 is performed by a product selector 14. Said selector makes it possible to choose which of said at least two maintenance products 10A, 10B , 10C will be connected to the venturi injector and, in fact, mixed with the water circulating in the pressurized water circuit 6.

Lesdits au moins deux produits d'entretien 10A, 10B, 10C sont contenus dans des contenants individuels fermés par un bouchon, par exemple de type bidon, et qui présentent un orifice au niveau de leur bouchon permettant à un conduit plongeur 143, relié au sélecteur de produit 14, d'atteindre le fond du contenant et donc le produit d'entretien. Le bouchon autorise un passage d'air suffisant dans le contenant pour permettre l'aspiration dudit produit d'entretien au travers du conduit plongeur 143. Ledit bouchon doit être également suffisamment étanche pour retarder le plus possible toutes fuites, par exemple si le dispositif est retourné ou couché accidentellement. Pour cela, ledit bouchon peut contenir par exemple un second orifice obturé par une membrane semi-perméable, laissant passer l'air mais bloquant les liquides.Said at least two maintenance products 10A, 10B, 10C are contained in individual containers closed by a cap, for example of the bogus type, and which have an orifice at their cap allowing a plunger conduit 143 connected to the selector of product 14, to reach the bottom of the container and therefore the cleaning product. The plug allows a sufficient air passage in the container to allow the suction of said maintenance product through the plunger 143. Said cap must also be sufficiently sealed to delay as much as possible any leaks, for example if the device is returned or accidentally lying down. For this, said cap may contain for example a second orifice closed by a semi-permeable membrane, allowing air to pass but blocking the liquids.

Chaque contenant desdits au moins deux produits d'entretien 10A, 10B, 10C est relié individuellement au sélecteur de produit 14 par le conduit plongeur 143, ce dernier peut comporter un clapet anti-retour empêchant par exemple un reflux d'un produit différent dans contenant, entrainant ainsi un mélange de différents produits qui peut nuire à leur efficacité.Each container of said at least two cleaning products 10A, 10B, 10C is individually connected to the product selector 14 by the plunger conduit 143, the latter may comprise a non-return valve preventing for example a reflux of a different product in the container. , resulting in a mix of different products that can affect their effectiveness.

Du fait que l'injecteur venturi 18 délivre un dosage constant desdits produits d'entretien 10A, 10B, 10C quelque soit de la quantité d'eau transitant dans le circuit d'eau sous pression 6, les concentrations de produits d'entretien 10A, 10B, 10C dans les contenants doivent être calculés pour que la concentration de produit contenue dans l'eau au niveau de la sortie d'eau 4 corresponde à la concentration optimale d'efficacité du produit d'entretien 10A, 10B, 10C.Because the venturi injector 18 delivers a constant dosage of said maintenance products 10A, 10B, 10C regardless of the amount of water passing through the pressurized water circuit 6, the concentrations of maintenance products 10A, 10B, 10C in the containers must be calculated so that the product concentration contained in the water at the water outlet 4 corresponds to the optimum concentration of efficacy of the cleaning product 10A, 10B, 10C.

Il est également possible d'ajuster et de contrôler la concentration de produit contenue dans l'eau au niveau de la sortie d'eau 4 en intégrant des buses calibrées, en amont du sélecteur de produit 14. Ainsi, la quantité de chaque produit d'entretien 10A, 10B, lOC aspiré par l'injecteur venturi, peut être contrôlée par les buses calibrées. Chaque buse calibrée est affectée à un produit d'entretien 10A, 10B, 10C de sorte que la concentration de produit contenue dans l'eau au niveau de la sortie d'eau 4 corresponde à la concentration optimale d'efficacité du produit d'entretien 10A, 10B, 10C. Si tout les produits ont une concentration optimale d'efficacité identique, on peut par exemple n'avoir besoin que d'une seule buse en aval du sélecteur de produit 14.It is also possible to adjust and control the product concentration contained in the water at the water outlet 4 by integrating calibrated nozzles, upstream of the product selector 14. Thus, the quantity of each product of maintenance 10A, 10B, IOC sucked by the venturi injector, can be controlled by the calibrated nozzles. Each calibrated nozzle is assigned to a maintenance product 10A, 10B, 10C so that the product concentration contained in the water at the level of the water outlet 4 corresponds to the optimum concentration of effectiveness of the maintenance product 10A, 10B, 10C. If all the products have an optimum concentration of identical efficiency, it may for example require only a single nozzle downstream of the product selector 14.

Le sélecteur de produit 14 ainsi que les contenants desdits au moins deux produits d'entretien 10A, 10B, 10C sont à l'instar du circuit d'eau sous pression 6, contenu à l'intérieur du réceptacle 8. Ledit sélecteur de produit 14, fixé à l'intérieur du réceptacle 8 sur une demi-coque 8A, présente sur la surface extérieure de ladite demi-coque 8A, un moyen de manipulation 141, comme montré sur la figure 3, permettant de choisir lequel desdits au moins deux produits d'entretien 10A, 10B, 10C sera connecté avec l'injecteur venturi 18. Un repère visuel 142, comme montré sur la figure 3, peut également être présent sur la surface extérieure de ladite demi-coque 8A afin d'identifier les produits sélectionnés au moyen du sélectionneur de produit 14.The product selector 14 as well as the containers of said at least two maintenance products 10A, 10B, 10C are like the pressurized water circuit 6 contained inside the receptacle 8. Said product selector 14 , fixed inside the receptacle 8 on a half-shell 8A, present on the outer surface of said half-shell 8A, a handling means 141, as shown in FIG. figure 3 , allowing to choose which of said at least two maintenance products 10A, 10B, 10C will be connected with the venturi injector 18. A visual cue 142, as shown in FIG. figure 3 may also be present on the outer surface of said half-shell 8A to identify the selected products by means of the product selector 14.

Par exemple, ledit dispositif de distribution, de dosage et de dilution automatique 1 peut contenir trois contenants de produits d'entretien 10A, 10B, 10C disposés côtes à côtes au sein du réceptacle 8. Les deux contenants de produits latéraux 10A et 10C ayant par exemple une contenance de un litre et le contenant central 10B une contenance de deux litres.For example, said dispensing, dosing and automatic dilution device 1 can contain three containers of maintenance products 10A, 10B, 10C arranged side by side in the receptacle 8. The two side product containers 10A and 10C having, example a capacity of one liter and the central container 10B a capacity of two liters.

Toujours selon cet exemple, ledit sélecteur de produit 14 peut être un sélectionneur quatre positions. Par sélectionneur de produit 14 quatre positions, on entend que ledit sélecteur de produit 14 comporte quatre entrées de produit et une sortie reliée à l'injecteur venturi 18. Trois de ces entrées de produit sont reliées aux produits d'entretien 10A, 10B, 10C et la quatrième entrée de produit est laissée libre ou alors elle peut être reliée à une source d'eau propre, par exemple à l'eau circulant dans le circuit d'eau sous pression 6 en amont de l'injecteur venturi 18. Ainsi, le moyen de manipulation 141, selon cette exemple, comporte quatre positions, trois positions correspondant à la sélection d'un produit d'entretien 10A, 10B, 10C et une quatrième position où aucun produit n'est relié et donc mélangé et dilué à l'eau circulant dans le circuit d'eau sous pression 6. Cette quatrième position peut permettre un rinçage dudit circuit d'eau sous pression 6 et du sélecteur de produit 14, entre l'utilisation de deux produits différents par exemple.Still according to this example, said product selector 14 may be a four-position selector. By product selector 14 four positions, it is understood that said product selector 14 comprises four product entries and an output connected to the venturi injector 18. Three of these product entries are connected to the maintenance products 10A, 10B, 10C and the fourth product inlet is left free or it can be connected to a source of clean water, for example water circulating in the pressurized water circuit 6 upstream of the venturi injector 18. Thus, the manipulation means 141, according to this example, comprises four positions, three positions corresponding to the selection of a maintenance product 10A, 10B, 10C and a fourth position where no product is connected and thus mixed and diluted with the water circulating in the pressurized water circuit 6. This fourth position can allow rinsing of said pressurized water circuit 6 and of the product selector 14, between the use of two different products for example.

Le circuit d'eau sous pression 6 comprend également une vanne tout ou rien 16, située entre l'entrée d'eau 3 et l'injecteur venturi 18. Ladite vanne tout ou rien 16, qui par défaut est fermée, est ouverte par un opérateur grâce à un moyen d'ouverture de vanne 20. Ledit moyen d'ouverture de vanne 20 étant accessible depuis l'extérieur du réceptacle 8, il peut être par exemple un bouton poussoir 20 à la surface du réceptacle 8.The pressurized water circuit 6 also comprises an on-off valve 16, located between the water inlet 3 and the venturi injector 18. Said on-off valve 16, which by default is closed, is opened by a With said valve opening means 20 being accessible from the outside of the receptacle 8, it can be for example a push button 20 on the surface of the receptacle 8.

Le moyen d'ouverture de vanne 20 est relié à la vanne tout ou rien 16 par un mécanisme de renvoi 21 qui transmet directement le mouvement appliquée par l'opérateur sur le moyen d'ouverture de vanne 20 à la vanne tout ou rien 16, permettant ainsi son ouverture.The valve opening means 20 is connected to the on-off valve 16 by a return mechanism 21 which directly transmits the motion applied by the operator to the valve opening means 20 to the on-off valve 16, thus allowing its opening.

L'ouverture de la vanne tout ou rien 16 permet à l'eau de circuler dans le circuit d'eau sous pression 6 entre l'entrée d'eau 3 et la sortie d'eau 4 en passant par l'injecteur venturi 18.The opening of the all-or-nothing valve 16 allows the water to circulate in the pressurized water circuit 6 between the water inlet 3 and the water outlet 4 via the venturi injector 18.

Le réceptacle 8 peut également comporter une poignée de transport 22 afin de faciliter la préhension ainsi que le transport du dispositif de distribution, de dosage et de dilution automatique 1. Pour faciliter également l'utilisation du dispositif de distribution, de dosage et de dilution automatique 1, le moyen d'ouverture de vanne 20 de la vanne tout ou rien 16 peut se situer dans la poignée de transport 22.The receptacle 8 may also include a carrying handle 22 to facilitate the gripping and the transport of the dispensing device, dosing and automatic dilution 1. To facilitate also the use of the dispensing device, dosing and automatic dilution 1, the valve opening means 20 of the on-off valve 16 may be located in the carrying handle 22.

Les figures 1 et 2 montrent un exemple de moyen d'ouverture de vanne 20 situé dans la poignée de transport 22. Le mouvement créé par une pression sur le moyen d'ouverture 20 par un opérateur est transmit à la vanne tout au rien 16 par le mécanisme de renvoi 21 comportant une pièce rigide en « L » 211 pivotant autour d'un axe 213 au niveau du coude dudit « L ». Une pression sur le moyen d'ouverture 20 situé à l'extrémité de la pièce rigide en « L » 211 entraine sa rotation autour de l'axe 213 et l'autre extrémité de la pièce rigide en « L » 211 applique un mouvement transversal à la vanne tout ou rien 16 entrainant son ouverture.The figures 1 and 2 show an example of valve opening means 20 located in the carrying handle 22. The movement created by pressure on the opening means 20 by an operator is transmitted to the all-nothing valve 16 by the return mechanism 21 having a rigid "L" piece 211 pivoting about an axis 213 at the elbow of said "L". Pressure on the opening means 20 at the end of the rigid "L" part 211 causes its rotation about the axis 213 and the other end of the rigid "L" part 211 applies a transverse movement to the all-or-nothing valve 16 causing it to open.

La figure 5 montre un autre exemple de moyen d'ouverture de vanne 20 et de mécanisme de renvoi 21. Dans cet exemple, le moyen d'ouverture de vanne 20 est situé au sommet du réceptacle 8 et le mouvement créé par une pression sur le moyen d'ouverture 20 par un opérateur est transmit à la vanne tout au rien 16 par le mécanisme de renvoi 21 comportant une barre de transfert de mouvement 214, une pièce 215 tournant autour d'un axe et une tige rigide 216 reliant la pièce 215 et la vanne tout ou rien 16. Une pression sur le moyen d'ouverture 20 entraine une rotation de la pièce 215 au moyen de la barre de transfert de mouvement 214 et cette rotation entraine un mouvement transversal de la tige rigide 216 qui est transmit à la vanne tout ou rien 16 entrainant son ouverture.The figure 5 shows another example of valve opening means 20 and return mechanism 21. In this example, the valve opening means 20 is located at the top of the receptacle 8 and the movement created by a pressure on the means of opening 20 by an operator is transmitted to the valve at nothing 16 by the return mechanism 21 comprising a movement transfer bar 214, a part 215 rotating about an axis and a rigid rod 216 connecting the part 215 and the valve all or nothing 16. A pressure on the opening means 20 causes a rotation of the part 215 by means of the movement transfer bar 214 and this rotation causes a transverse movement of the rigid rod 216 which is transmitted to the valve while or nothing 16 causing its opening.

Ledit réceptacle 8 peut également comporter des rainures 24 sur sa surface extérieure afin de pouvoir enrouler le tuyau faisant la liaison entre l'arrivée d'eau et l'entrée d'eau 3. Lesdites rainures 24 peuvent présenter un ou plusieurs rétrécissements 241 permettant de coincer ledit tuyau et ainsi de le maintenir enrouler autour du réceptacle 8.Said receptacle 8 may also include grooves 24 on its outer surface so as to be able to wind the pipe connecting the water inlet and the water inlet 3. Said grooves 24 may have one or more narrowing 241 allowing wedging said pipe and thus keeping it wrapped around the receptacle 8.

Les demi-coques 8A et 8B formant le réceptacle 8 peuvent être fixées l'une à l'autre au moyen de vis. La demi-coque 8B, opposée à la demi-coque 8A comportant le moyen de manipulation 141 du sélecteur de produit 14, peut comporter une trappe 82 permettant l'accès aux contenants des produits d'entretien 10A, 10B, 10C et aussi leur remplacement lorsqu'ils sont vide, comme montré sur la figure 4.The half-shells 8A and 8B forming the receptacle 8 can be fixed to each other by means of screws. The half-shell 8B, opposite to the half-shell 8A comprising the manipulation means 141 of the product selector 14, may comprise a hatch 82 allowing access to the containers of the maintenance products 10A, 10B, 10C and also their replacement when empty, as shown on the figure 4 .

Ladite trappe 82 peut également présenter des moyens de visualisation 84 du niveau restant de produit d'entretien 10A, 10B, 10C dans les contenants. Ces moyens de visualisation 84 peuvent être par exemple des ouvertures au niveau de la trappe 82 ou bien une zone translucide sur ladite trappe 82 laissant entrevoir les contenants des produits d'entretien 10A, 10B, 10C eux même translucides.Said hatch 82 may also have display means 84 for the remaining level of cleaning product 10A, 10B, 10C in the containers. These display means 84 may for example be openings at the level of the hatch 82 or a translucent zone on said hatch 82 leaving a glimpse of the containers of the maintenance products 10A, 10B, 10C themselves translucent.

Ladite trappe 82 peut également présenter un moyen de verrouillage 86, par exemple une serrure à clé ou bien un cadenas, empêchant au personnel non qualifié ou non autorisé d'accéder aux contenants des produits d'entretien 10A, 10B, 10C.Said door 82 may also have a locking means 86, for example a key lock or a padlock, preventing unqualified or unauthorized personnel to access the containers of the care products 10A, 10B, 10C.

En fonctionnement, un opérateur peut ainsi transporter facilement le dispositif de distribution, de dosage et de dilution automatique 1 selon l'invention grâce à sa poignée de transport ainsi qu'à son poids réduit, lié à l'utilisation de contenants de produits d'entretien 10A, 10B, 10C faible , le poids total du dispositif pouvant être compris entre cinq et sept kilos avec deux contenants de un litres et un contenant de deux litres. L'opérateur peut ainsi apporter le dispositif de distribution, de dosage et de dilution automatique 1 où il est utile, et peut le brancher à une arrivée d'eau au moyen du tuyau. L'ouverture de l'arrivée d'eau n'entraine pas un écoulement d'eau au travers du circuit d'eau sous pression 6 car la vanne tout ou rien 16 bloque cette circulation. L'opérateur peut ainsi choisir parmi les produits d'entretien 10A, 10B, 10C au moyen du sélecteur de produit 14. Une action continue de l'opérateur sur le moyen d'ouverture de vanne 20 entraine l'ouverture de la vanne tout ou rien 16 et la circulation de l'eau dans le circuit d'eau sous pression 6 commence, permettant le mélange et la dilution, au niveau de l'injecteur venturi 18, du produit sélectionné. Le mélange, de concentration en produit constante, est récupéré au niveau de la sortie d'eau 4. Un arrêt de l'action sur le moyen d'ouverture de vanne 20 entraine la fermeture de la vanne tout ou rien 16 et stop donc la circulation d'eau dans le circuit d'eau sous pression 6, évitant de fait tout risque de fuite ou d'écoulement non désiré. L'opérateur peut alors selon ses besoins choisir un autre produit ou aucun grâce au sélecteur de produit 14.In operation, an operator can easily transport the dispensing device, metering and automatic dilution 1 according to the invention with its carrying handle and its reduced weight, related to the use of containers of products of maintenance 10A, 10B, 10C low, the total weight of the device can be between five and seven kilos with two containers of one liter and a container of two liters. The operator can thus bring the dispensing device, dosing and automatic dilution 1 where it is useful, and can connect it to a water supply by means of the pipe. The opening of the water inlet does not cause a flow of water through the pressurized water circuit 6 because the all-or-nothing valve 16 blocks this circulation. The operator can thus choose from the maintenance products 10A, 10B, 10C by means of the product selector 14. Continuous action of the operator on the valve opening means 20 causes the on-off valve 16 to open and the circulation of the water in the pressurized water circuit 6 begins, allowing mixing and dilution, level of the venturi injector 18, of the selected product. The mixture, of constant product concentration, is recovered at the level of the water outlet 4. Stopping the action on the valve opening means 20 causes the on-off valve 16 to close and thus stops the circulation of water in the pressurized water circuit 6, thereby avoiding any risk of leakage or unwanted flow. The operator can then according to his needs choose another product or none thanks to the product selector 14.

Ainsi, on voit bien que le dispositif de distribution, de dosage et de dilution automatique selon l'invention permet une distribution simplifiée, optimisée et surtout mobile selon les besoins des différents produits d'entretien qu'il comprend, délivrant une dose optimale de produit en fonction du volume d'eau et cela permettant d'éviter les gaspillages de produit par surdosage et donc limitant les couts et l'impact sur l'environnement.Thus, it can clearly be seen that the dispensing, dosing and automatic dilution device according to the invention allows a simplified, optimized and above all mobile distribution according to the needs of the various maintenance products that it comprises, delivering an optimal dose of product. depending on the volume of water and this avoids wasting product overdose and therefore limiting the costs and impact on the environment.
