- water fountains are devices intended to distribute at will fresh and hot water, from a water canister which is replaced when it is exhausted, or when its expiration date intervenes. , or from the drinking water network.
- These fountains essentially comprise a water supply system, a water / heating and cooling distribution and cooling system, and various control elements.
- Bacterial contamination can occur at many stages of the preparation of the fountain, its loading with water and its use.
- the fountain generally comprises, at least for the fountains with carboy, a percussion system of the carboy or bottle, which can be accidentally contaminated with each handling.
- the lid of the cylinder can itself be contaminated during any manipulation, including during transport and storage, or during the installation of the cylinder.
- kits disposable water distribution “kits” or removable tubs which are replaced or disinfected approximately 4 times a year.
- Disinfection systems consist of machines supplying hot water, and which are periodically connected to the fountains, in order to disinfect the system for a sufficient time, by circulating hot water at 90-95 ° C. . These machines are very effective, but the disinfection efficiency is naturally dependent on the frequency with which one decides to use them.
- the invention relates to a device and method called "integral thermal disinfection” characterized in that the water contained in a “water fountain” (of any type, as indicated above) is permanently disinfected by heating, at a predetermined temperature and for a predetermined time, all with a predetermined frequency, all (or almost all, as will be seen below) of the pipes, tubs, taps, seals, fittings, and other elements of the circuit or the water supply, distribution and circulation network of said fountain, located between the percussion system of the cylinder (or the water supply from the network) and the distribution tap.
- a water fountain of any type, as indicated above
- all of the pipes, tanks, taps, seals and other elements we mean either all the pipes and other elements, or at least as large a part as possible of these pipes and other items, if possible almost all, in any event a fraction large enough to ensure the thermal disinfection function of the water of the invention.
- the treatment temperature and / or the frequency of treatment can also be varied.
- a water fountain is essentially composed of a water inlet zone (in the case of a cylinder fountain, this zone is mainly composed
- a receptacle of the carboy comprising a means of "percussion" of the carboy, that is to say of vertical positioning of the carboy and of perforation of its cover, and of the beginning of the tubing; in the case of a fountain - network, these are the means of connecting the fountain to the drinking water supply network and also the start of the tubing)
- the fountain has two circuits, one for delivering water at normal or temperate temperature, and the other for delivering water cooled or hot, with seals, fittings and other parts corresponding to the two circuits and to their order,
- some fountains also include localized heating means or means of connection with hot water disinfection machines.
- the invention therefore relates to a device and method for thermal disinfection of drinking water from a water fountain, integrated into said fountain, and characterized in that it is continuously disinfected, by actions carried out at preprogrammed time intervals, the water contained in the supply or distribution system or circuit of a "water fountain" (of any type, as indicated above) by heating, to a predetermined temperature and for a predetermined time, all with a predetermined frequency, the entirety of said system or circuit and therefore of the water contained in all the pipes (and / or tanks, tanks, and other elements of the system or circuit in contact with water) of said fountain, located between the cylinder percussion system (or the mains water supply) and the distribution tap.
- a water fountain of any type, as indicated above
- the tubes, or the receptacle, possibly the incorporated container (s), or the “kits” described above, or even the distribution valve (s), include seals, fittings, roughness, end pieces, interstices and the like, which form as many potential nests where bacteria can cling to and then proliferate, and where it is difficult to dislodge or destroy them.
- biofilm which forms on the walls and is made up of colonies of non-pathogenic bacteria.
- This biofilm comes in the form of a transparent and sticky film which, on the one hand, is not pleasant and which, on the other hand, forms an ideal culture medium for pathogenic bacteria.
- Such a biofilm therefore represents a potential permanent danger, which promotes the proliferation of pathogenic bacteria as soon as these are present for a sufficiently long time.
- the invention solves all the problems which have just been described, including the prevention or destruction of the biofilm (or prevention of its formation), disinfection of all interstices, fittings, elbows, etc. and even cracks and microcracks which inevitably appear in the metal, even on a so-called “smooth” tubing: such microcracks constitute as many nests for bacteria impossible to disinfect effectively with known systems, and all the more pernicious as they are invisible to the attendant periodic cleaning.
- the invention relates in particular to a device and method for thermal disinfection of the water of a water fountain, integrated into said fountain, characterized in that one disinfects thermally, permanently, that is to say by specific thermal actions but at preprogrammed intervals, preferably regular, the water contained in a “water fountain” (of any type, as indicated above) by heating, to a predetermined temperature and for a predetermined time, all with a predetermined frequency, and all (that is to say all of these parameters) being adapted to obtain the desired thermal disinfection effect, the metal and / or alloy constituting the set of pipes of said fountain, located between the percussion system of the cylinder (or the water supply from the network) and the distribution tap, and / or directly the water contained in all the pipes.
- a water fountain of any type, as indicated above
- the pipes are heated by insertion into the water supply (and distribution) pipes of said circuit, over the entire length thereof, or substantially their entire length. , of a tube called "current flow", that is to say of a metal tube heated by the Joule effect by the passage of an electric current capable of bringing the temperature of the water to the desired value under the desired operating conditions, and suitable for obtaining the desired thermal disinfection.
- current flow that is to say of a metal tube heated by the Joule effect by the passage of an electric current capable of bringing the temperature of the water to the desired value under the desired operating conditions, and suitable for obtaining the desired thermal disinfection.
- a non-limiting example of supplying such a current-passing tube, which is of known type, is of the order of 1000 A at a low voltage of approximately 3 V.
- a current flow tube for the pipes and another heating method, for example a sheath comprising an electrical resistance, for the other elements such as tanks, taps, valves and the like.
- the metal or alloy of the pipes is heated by adjoining the pipe, over its entire length, a heating resistor capable of indirectly bringing the temperature of the water to the desired value under the desired operating conditions and suitable for obtaining the desired thermal disinfection.
- the desired or adapted value is of the order of 90 - 95 ° C and that the desired or adapted conditions are those which correspond to a time and a frequency of treatment which are both sufficient to break down the proliferation of bacteria, destroy pathogenic bacteria and preferably prevent the formation of biofilm, while remaining economically satisfactory.
- the invention therefore provides self-disinfection by periodic integral heating of all the tubes (and / or tanks, etc.) at a disinfection temperature.
- This heating is made possible by the low thermal inertia of the materials used for the design of all the pipes and tubs, etc., provided of course that these elements are made of a thermally conductive material, such as quality stainless steel. well-known food and metals or similar alloys.
- the invention makes it possible for the first time to produce water whose sanitary quality is permanently identical to the quality of the water contained in the delivered bottle. Supposing that the water in the bottle is accidentally infected before delivery, the system according to the invention would be capable of destroying the pathogenic flora.
- the percussion or water inlet system as well as the tap or taps, are also disinfected by the method according to the invention.
- the treatment according to the invention will for example be carried out by a rise to 90 - 95 ° C for approximately 10 to 20 mins, preferably around 10 mins, every 24 hours, preferably every night.
