Abstract

The present invention relates to an installation for the public distribution of filtered water, cold or not, gasified or fresh. The public water fountain consists of a ventilated house with insulation panels and a complex installation of filtration, cooling, gasification and water treatment. In the first stage, the water in the sector goes through a prefilter, under a UV lamp, then by activated carbon filters and silver ions. To maintain the quality of the water, the system is automatically hygienised using a system called μSterilDraft®. After the filtration step, the water is distributed in three types: filtered, cooled and gasified; filtered and cooled; filtered and at room temperature. Then the water is directed to the dispensing valves controlled by buttons mounted on the control panel. All this system of filtration, cooling, hygienisation and water distribution is controlled by an electronic programmer.

Description

The present invention relates to a public water fountain, more specifically an installation for the public distribution of filtered water, cold or not, gasified or fresh. Publicly-owned water supply systems with gravity feeders are known: - hand pump (piston); - Drilled fountain, electrically actuated (with hydrophore group) etc. All these solutions have the disadvantage of the lack of a high-end filtration system and a permanent control of the quality and temperature of the water. Also, these facilities do not dispense fresh filtered water at room temperature, cold filtered water and filtered, cold and carbonated water. There are public sources of carbonated water which have the disadvantage of being in inaccessible premises, that is to say, in seaside resorts or in specialty shops, dedicated to private consumption. In the case of the public water fountain, these disadvantages disappear, because the device consists in the installation, in public premises or at private companies and / or in department stores or supermarkets, maisonettes for distribution of water. Inside these houses are mounted refrigeration and water distribution equipment, equipped with a high-end system of water filtration, based on silver ions on the sector water pipe and base 30 UV light on the water dispensing cap on the front panel of the unit. In addition to the temperate (at mains temperature) and filtered and cold filtered water delivery options, the device also offers the option to select filtered water. cold and carbonated (to which CO2 was added after cooling). The object of the invention is to supply the public with filtered fresh water, cold and carbonated.

The present invention aims to overcome the drawbacks of a conventional fountain by installing a public fountain distributing cool filtered water temperate, cold and gasified. The public water fountain concerns the installation 10 in public premises of apparatus for the distribution of fresh, cold, temperate and carbonated drinking water, which consist of the following components: - a house with insulation panels and, optionally, fans for extracting and discharging hot air during the summer and blowing hot air for heating during the winter; - filtration system, consisting of filters for suspended particles and activated carbon and silver ion filters; water cooling system; 20 - gasification plant for water; water distribution facility; payment system, on public paid water distribution facilities; - automatic system of hygienization of the water distribution system, by the system upSterildraft "this system is invented by our company and certified, and ensures the mechanical and biological sanitization of the conduits for liquids (Patent No. 118278) ADVANTAGES: 30 1. Allows permanent access to a significant amount of fresh water and carbonated water directly from the sector and represents a hygienic and ecological option, because the maintenance of the public water fountain is ensured by companies specialized in the field, the installation MARGI1-FR-1CU / R0 - 3 - is scheduled to perform periodic hygienization by the system, dSterildraft "and because the water distribution system is entirely made of stainless steel; 2. The public water fountain is economical because filtered, cold or temperate water is provided free of charge to the public and because carbonated water is offered at the best price on the carbonated water market; 3. The solution is practical, because you do not have to go to stores, big or small, to get the water or block the space of your refrigerator to cool it, but you can take its filtered, chilled water or tempered at the public fountain; 4. The most important aspect is that this water is ecological because, thanks to this process, the transport of the bottles is eliminated and, at the same time, their negative impact on the environment (polluting emissions) by reducing The quantity of plastic bottles introduced on the market is substantially taken into account, taking into account that the public water fountain makes it possible to obtain water in its own containers, which can also be reused. 5. In addition to all the advantages mentioned above, which our appliances offer in an irreproachable way, we have desired and we hope to have succeeded in bringing them together in a modern, pleasant, and why not attractive, 25 to a remarkable design for the realization from which we used materials of the best quality. 6. The public water fountain may be installed in the premises of private companies or public establishments, on the prior approval of the territorial and / or governmental administration 30, which wishes to offer citizens a high quality, safe water and controlled. 7. Statistically speaking, if ten public water fountains distribute 6,000,000 liters of water, the families who are the beneficiaries of these services make a saving of more than one million people. euro, replacing bottled water. 8.
