Il est clair que cette description est donnée à titre d'exemple, et n'a pas de caractère limitatif. The following description and drawing will provide a better understanding of the objects and advantages of the invention. It is clear that this description is given by way of example, and is not limiting in nature.
Dans les dessins - la figure 1 est un schéma fonctionnel du dispositif selon l'invention; - la figure 2 illustre plus précisément le bloc réfrigérant; - la figure 3 représente de façon schématique l'installation d'un dispositif selon l'invention sur un chassis tubulaire à roulettes. Le dispositif selon l'invention est destiné dans le présent exemple à être installé dans n'importe quel site dépourvu d'alimentation en eau et d'électricité, et les dimensions données correspondent sensiblement à la production et à la distribution de 30 litres d'eau réfrigérée à une température comprise en 9 et 15 . Toutes les dimensions citées dans la description qui suit peuvent naturellement être adaptées selon des besoins spécifiques différents. In the drawings - Figure 1 is a block diagram of the device according to the invention; - Figure 2 illustrates more precisely the refrigerant block; - Figure 3 shows schematically the installation of a device according to the invention on a tubular chassis with wheels. The device according to the invention is intended in the present example to be installed in any site devoid of water supply and electricity, and the given dimensions substantially correspond to the production and distribution of 30 liters of water. refrigerated water at a temperature of 9 to 15. All the dimensions mentioned in the following description can naturally be adapted according to different specific needs.
De façon résumée, le dispositif est organisé autour d'un réservoir principal d'eau à température ambiante, dont l'eau est refroidie continuellement avant d `être versée sur demande de l'utilisateur dans un robinet 2. Briefly, the device is organized around a main water tank at ambient temperature, the water of which is cooled continuously before being poured at the request of the user into a tap 2.
Plus précisément, comme on le voit sur la figure 1, le dispositif selon l'invention comporte naturellement d'abord un réservoir principal 1 d'eau à température ambiante. Ce réservoir d'une contenance de 30 litres dans le présent exemple non limitatif, est isotherme. Il est par exemple constitué d'un volume cylindrique de diamètre 300 mm et de Longueur 450 mm en plastique alimentaire, telle que polyéthylène haute densité à très haut poids moléculaire pour contact alimentaire, recyclable. Il comporte un manchon de remplissage 3 en plastique dit alimentaire sur sa partie latérale qui le relie avec la coque de protection 4 et d'un autre manchon d'alimentation 6 en plastique dit alimentaire sur sa partie supérieure qui le relie avec la coque de protection 4. More specifically, as seen in Figure 1, the device according to the invention naturally comprises first a main tank 1 of water at room temperature. This tank with a capacity of 30 liters in the present non-limiting example, is isothermal. It consists for example of a cylindrical volume of diameter 300 mm and 450 mm length of food plastic, such as high density polyethylene with a high molecular weight for food contact, recyclable. It comprises a filling sleeve 3 of said plastic food on its side which connects with the protective shell 4 and another feed sleeve 6 said plastic food on its upper part which connects with the protective shell 4.
La coque de protection 4 est par exemple constituée d'un volume cylindrique de diamètre 400 mm et de Longueur 600 mm en plastique alimentaire, telle que polyéthylène haute densité à très haut poids moléculaire pour contact alimentaire, recyclable. The protective shell 4 is for example made of a cylindrical volume of 400 mm diameter and 600 mm length of food plastic, such as high density polyethylene with a very high molecular weight for food contact, recyclable.
Il comporte un bouchon de remplisssage 5 en polypropylène sur sa partie latérale et d'un robinet 2 sur sa partie supérieure. It comprises a filling plug 5 polypropylene on its side and a valve 2 on its upper part.
Coté utilisateur, un point de distribution d'eau 2 comporte un robinet à ouverture progressive, ouverture total<B>:</B> 3I4 de tour. Ce robinet est en Polypropylène de type alimentaire. Un bloc de réfrigération à effet Peltier est installé sur la partie basse du réservoir 1. Il se compose principalement d'une plaque Peltier 7, d'un plot 8 en alliage solidarisé à la base du réservoir, et d'un radiateur 9, disposé sous la plaque Peltier 7 et adapté à évacuer la chaleur extraite de ladite plaque Peltier 7. On the user side, a water distribution point 2 comprises a tap with progressive opening, total opening <B>: </ B> 3I4 turn. This faucet is Polypropylene food type. A Peltier refrigeration unit is installed on the lower part of the tank 1. It consists mainly of a Peltier plate 7, an alloy stud 8 secured to the base of the tank, and a radiator 9 disposed under the Peltier plate 7 and adapted to evacuate the heat extracted from said Peltier plate 7.
L'effet Peltier est connu en soi. On rappelle ici simplement qu'il consiste à inverser la polarité de deux conducteurs de taille différente, permettant à la plaque semi-conducteur de dégager de la chaleur sur une de ses faces (ici sa face inférieure) et de capter de la chaleur sur l'autre face(ici la face côté réservoir rafraîchi 6). Le froid est récupéré par un plot en alliage spécial anodisé (ici alliage Aluminium 6082 anodisé) qui est en contact intime avec la surface de la plaque dégageant du froid jusqu'à -10 C. The Peltier effect is known per se. It is simply recalled here that it consists in inverting the polarity of two differently sized conductors, allowing the semiconductor plate to release heat on one of its faces (here its lower face) and to capture heat on the surface. other side (here the refreshed tank side 6). The cold is recovered by a special anodized alloy pad (here alloy anodized 6082 aluminum) which is in intimate contact with the surface of the plate giving off cold up to -10 C.
La plaque Peltier 7 est de type alimentée en 12 volts, et d'une puissance de 53 watts. Il est clair qu'un dimensionnement différent peut-être choisi en fonction des besoins en eau dans lequel le dispositif doit-être installé. The Peltier 7 plate is a 12-volt type, with a power of 53 watts. It is clear that a different dimensioning may be chosen depending on the water requirements in which the device is to be installed.
Le radiateur 9 est en aluminium. Il refroidi par deux ventilateurs 10 et 11 également alimenté en 12 volts. Ces ventilateurs 10 & 11 sont par exemple à moteur à courant continu à commutation électrique et rotor extérieur, de puissance 1.5 watts pour un débit de quelques dizaines de mètres cubes par heure. The radiator 9 is made of aluminum. It cooled by two fans 10 and 11 also powered in 12 volts. These fans 10 & 11 are for example a DC motor with electrical switching and external rotor, with a power of 1.5 watts for a flow of a few tens of cubic meters per hour.
Un thermostat de type classique, toujours alimenté en 12 volts, assure la régulation du fonctionnement du bloc Peltier en fonction de la température de l'eau observée dans le réservoir 1. Une température de 12 étant par exemple choisie comme température cible. A conventional thermostat, always powered by 12 volts, regulates the operation of the Peltier block according to the water temperature observed in the tank 1. A temperature of 12 being for example chosen as the target temperature.
Comme on l'a vu, l'ensemble du bloc réfrigérant (plaque 7, plot 8, radiateur 9, ventilateurs 10 & 11, thermostat 14) est alimenté en 12 volts et protégé par un chassis cylindrique 13 en P.V.C, et comporte par ailleurs, un montage électronique simple à base de pont de diodes et de condensateurs, de type connu de l'homme du métier, et non détaillé plus avant ici. As we have seen, the entire refrigeration unit (plate 7, pad 8, radiator 9, fans 10 & 11, thermostat 14) is supplied with 12 volts and protected by a cylindrical frame 13 of PVC, and moreover comprises a simple electronic bridge-based arrangement of diodes and capacitors, of a type known to those skilled in the art, and not detailed further here.
On comprend que le dimensionnement des éléments du bloc Peltier est déterminé par le choix d'une puissance de refroidissement suffisante pour refroidir 30 litres d'eau en 4 heures à partir d'eau à 25 , ce qui correspond à la production de<B>150</B> verres de 20 cl d'eau fraîche, ce qui devrait répondre à la majeure partie des besoins sur un site occupé par des personnes, de l'ordre de 50 consommateurs d'eau. It is understood that the dimensioning of the elements of the Peltier block is determined by the choice of a sufficient cooling power to cool 30 liters of water in 4 hours from water to 25, which corresponds to the production of <B> 150 </ B> glasses of 20 cl of fresh water, which should meet most of the needs on a site occupied by people, of the order of 50 consumers of water.
Ce réservoir 1 dans sa coque protectrice 4 est posé sur un berceau 15 constitué d'un chassis tubulaire par exemple, de section 25 mm. Muni de roulettes 16 sur la partie avant du berceau, une main courante 17, permet de tirer l'ensemble pour le déplacer. Sur chaque côté du berceau, se trouvent deux barres servant de poignée afin de soulever l'ensemble et de le transporter sur son site où dans un véhicule. This tank 1 in its protective shell 4 is placed on a cradle 15 consisting of a tubular frame for example, 25 mm section. Equipped with wheels 16 on the front part of the cradle, a handrail 17, pulls the assembly to move it. On each side of the cradle, there are two bars used as a handle to lift the whole and transport it on its site or in a vehicle.
Ce dispositif complet peut-être alimenté en veille, la nuit sur une alimentation 220 Volts afin de refroidir l'eau du réservoir pour l'amener à la température voulue, ce qui permet le jour, d'amener l'ensemble sur le site de prédilection et grâce au bloc réfrigérant à effet Peltier, de maintenir cette eau fraîche par une alimentation en 12 volts ,grâce à une prise allume-cigare sur le véhicule ou par l'intermédiaire d'une batterie placée sur la base du berceau, rendant le système complètement autonome. This complete device can be powered on standby, at night on a 220-volt power supply to cool the water of the tank to bring it to the desired temperature, which allows the day, to bring the whole to the site of and thanks to the Peltier refrigerant unit, to maintain this fresh water by a 12-volt power supply, thanks to a cigarette lighter socket on the vehicle or via a battery placed on the base of the cradle, making the completely autonomous system.
La portée de la présente invention ne se limite pas aux détails des formes de réalisation ci-dessus considérés à titre d'exemple, mais s'étend au contraire aux modifications à la portée de l'homme de l'art. The scope of the present invention is not limited to the details of the above embodiments considered by way of example, but extends instead to modifications within the scope of those skilled in the art.
