DISPOSITIF ET PROCEDE DE MISE EN HYGIENE PAR MICRONISATION D'EAU SOUS VIDE DEVICE AND METHOD FOR HYGIENE BY MICRONIZATION OF VACUUM WATER
Certains appareils d'aspiration en milieu humide, destinés au nettoyage des surfaces, murs ou sols, sont actuellement proposés mais pas pour la " mise en hygiène" des surfaces qui est l 'objectif de la présente invention : cet objectif va en effet au-delà d'une part de ce l'on appelle d'une manière classique et habituelle le nettoyage, qui a essentiellement pour objectif une propreté visuelle, et d' autre part même ce que l 'on peut qualifier d'ultra propreté qui concerne le fond des pores et/ou des fibres du support à nettoyer. La présente invention permet non seulement d'atteindre un excellent niveau de nettoyage, contrôlé visuellement suivant un indice bien meilleur que ceux obtenus avec des appareils traditionnels, mais également de très bons niveaux d'ultra propreté et surtout de mise en hygiène par élimination des germes, bactéries, moisissures, au fond des pores et/ou des fibres, tels que définis dans/et à la fin de la présente description.Certain suction devices in a humid environment, intended for cleaning surfaces, walls or floors, are currently offered but not for the "hygiene" of surfaces which is the objective of the present invention: this objective goes in fact to beyond on the one hand what is called in a conventional and usual manner cleaning, which essentially aims at visual cleanliness, and on the other hand even what can be described as ultra cleanliness which concerns the bottom of the pores and / or fibers of the support to be cleaned. The present invention not only achieves an excellent level of cleaning, visually controlled according to a much better index than those obtained with traditional devices, but also very good levels of ultra cleanliness and above all hygiene by eliminating germs. , bacteria, molds, at the bottom of the pores and / or fibers, as defined in / and at the end of this description.
On qualifiera donc dans la description ci-après le dispositif est procédé de l' invention comme étant une "mise en hygiène" pour bien le distinguer du seul nettoyage obtenu avec les appareils existants.We will therefore qualify in the description below the device is a method of the invention as being "hygienic" to distinguish it from the only cleaning obtained with existing devices.
En effet, ceux-ci procèdent par mouillage du support à nettoyer au moyen d'une simple pulvérisation d'eau projetée sur ledit support, et successivement par la récupération de l 'eau sale au moyen de son aspiration par un courant d'air en dépression.Indeed, these proceed by wetting the support to be cleaned by means of a simple spraying of water projected on said support, and successively by recovering the dirty water by means of its suction by a stream of air in depression.
De tels appareils procèdent généralement par une pulvérisation grossière d'eau sous une pression élevée, et sa récupération est effectuée par un faible débit d'air de 25 à 40 litres par minute soumis à une dépression de -1800 à -2500 mm de colonne d'eau seulement, l' une et l 'autre de ces conditions de travail ne permettent pas une mise en hygiène des supports, ni même un nettoyage profond.Such devices generally proceed by a coarse spraying of water under high pressure, and its recovery is carried out by a low air flow rate of 25 to 40 liters per minute subjected to a vacuum of -1800 to -2500 mm of column d only water, both of these working conditions do not allow a hygienic supports, or even a deep cleaning.
De tels appareils sont aussi particulièrement mal adaptés non seulement à la mise en hygiène mais même au nettoyage des textiles tissés ou non tissés (sur sols, murs ou meubles) , dont le séchage n'est obtenu qu'en 24 heures et parfois plus. En outre, au cours de leur emploi on ne peut éviter des écoulements d'eau indésirables au niveau de leur tête de travail mise en contact avec le support à nettoyer, l'organe de pulvérisation qui lui est associé et qui est extérieur au conduit d'aspiration de l'air n ' étant pas lui-même contenu dans un conduit particulier au delà de la sortie de la pulvérisation qui, de ce fait se fait à l'air libre. On peut citer par exemple comme art antérieur connu le document allemand G9105512.1 décrivant un appareil de nettoyage comportant un réservoir d'eau avec un dispositif de chauffage, une pompe pour transporter l'eau jusqu' à un tuyau d' amener ainsi qu'un réservoir de collecte de l'eau sale auquel est raccordé une pompe à vide et depuis lequel s'étant un tuyau d' aspiration : le tuyau d'amenée et le tuyau d' aspiration mènent à une tête de nettoyage rigide prévu exclusivement pour nettoyer des textiles au sol ; les plâtres, terre cuite, thermoplastique, crépis ne peuvent pas être nettoyés ; et l'ensemble des organes de l 'appareil de nettoyage sont contrôlés par des microprocesseurs et un tableau de commande à partir duquel l'opérateur peut diriger les opérations.Such devices are also particularly ill-suited not only for hygiene but even for cleaning woven or non-woven textiles (on floors, walls or furniture), the drying of which is obtained only in 24 hours and sometimes more. In addition, during their use, undesirable water flows cannot be avoided at the level of their working head brought into contact with the support to be cleaned, the spraying device which is associated with it and which is outside the air suction duct not being itself contained in a particular duct beyond the outlet of the spraying which, therefore, takes place at the open air. Mention may be made, for example, as a known prior art, of the German document G9105512.1 describing a cleaning apparatus comprising a water tank with a heating device, a pump for transporting the water to a supply pipe as well as a dirty water collection tank to which a vacuum pump is connected and from which having a suction pipe: the supply pipe and the suction pipe lead to a rigid cleaning head intended exclusively for cleaning textiles on the floor; plaster, terracotta, thermoplastic, plaster cannot be cleaned; and all the parts of the cleaning device are controlled by microprocessors and a control panel from which the operator can direct operations.
On peut également citer le document allemand G8613576.7 qui décrit un appareil de nettoyage répondant en partie à l'inconvénient cité précédemment puisque le conduit d'amenée d'eau sous pression est situé à l'intérieur de la bouche d'aspiration de l'air, l'ensemble des autres éléments étant également décrits comme du reste dans la présente invention, mais dans ce document allemand suivant un mode de réalisation spécifique puisque l ' objectif est de pulvériser un solvant sous pression contre la surface d'un mur à nettoyer pour y détacher des particules de peinture.Mention may also be made of the German document G8613576.7 which describes a cleaning device which partly responds to the drawback mentioned above since the pressure water supply duct is located inside the suction mouth of the air, all the other elements being also described as elsewhere in the present invention, but in this German document according to a specific embodiment since the objective is to spray a solvent under pressure against the surface of a wall to clean to remove paint particles.
Ces divers appareils peuvent donc endommager la surface que l'on veut traiter surtout si celle-ci est fragile tel que pour des textiles et de tout façon ne permettent pas leur application pour une mise en hygiène comme celui recherché dans la présente invention et décrit ci-après, ni même un nettoyage de très bonne qualité.These various devices can therefore damage the surface that is to be treated, especially if it is fragile such as for textiles and in any case does not allow their application for hygienic purposes such as that sought in the present invention and described below. -afterwards, or even a very good quality cleaning.
D'autres appareils travaillant à la vapeur respectent certes un peu mieux la qualité de surface que l'on veut nettoyer mais d'une part n'évite pas des coulures éventuelles par condensation de la vapeur sur la surface et de plus du fait de la température élevée de la vapeur, leur utilisation n' est pas possible non plus pour certains matériaux à nettoyer et ne permet pas une désinfection instantanée. L' appareil de la présente invention permet : - soit de mettre en oeuvre un procédé nouveau suivant l' invention répondant aux inconvénients des procédés connus pour non seulement un nettoyage profond qualifié d'ultra propreté mais également et surtout une mise en hygiène par humidification, au moyen d'eau froide, ou modérément chauffée des surfaces à traiter, dont le séchage est rapidement obtenu, et cela grâce à une très fine micronisation de l 'eau diffusée en faible quantité, simultanément soumise à une très forte aspiration d'air pouvant atteindre jusqu'à 100 litres par seconde, avec une dépression 65 KPa, - soit d'effectuer un nettoyage par brouillard à haute pression avec également une forte aspiration.Other devices working with steam certainly respect the quality of the surface that we want to clean a little better, but on the one hand does not avoid possible drips by condensation of the steam on the surface and moreover due to the high steam temperature, their use is also not possible for certain materials to be cleaned and does not allow instant disinfection. The apparatus of the present invention allows: - Or to implement a new process according to the invention responding to the drawbacks of known processes for not only deep cleaning qualified as ultra cleanliness but also and above all hygienic treatment by humidification, using cold water, or moderately heated surfaces to be treated, whose drying is quickly obtained, and this thanks to a very fine micronization of the water diffused in small quantity, simultaneously subjected to a very strong suction of air which can reach up to 100 liters per second, with a vacuum 65 KPa, - either to perform a cleaning by high pressure mist with also a strong suction.
Pour le premier procédé par micronisation, au moyen d'un dispositif nouveau suivant l'invention et décrit ci-après :For the first micronization process, using a new device according to the invention and described below:
- on diffuse de l 'eau propre sur la surface du support à mettre en hygiène sous la forme d'une véritable micronisation au sein et par au moins un terminal disposé contre ladite surface, d'un brouillard composé de très fines gouttelettes d'au plus 30 microns, soit de préférence de 5 à 10 microns, seulement obtenues en basse pression, légèrement supérieur d'au moins 0,1 bar par rapport à celle régnant dans l 'ambiance extérieure, et au maximum sous une pression de 2 bar environ ;- clean water is diffused on the surface of the support to be hygienized in the form of a true micronization within and by at least one terminal disposed against said surface, of a mist composed of very fine droplets of at plus 30 microns, preferably 5 to 10 microns, only obtained at low pressure, slightly higher by at least 0.1 bar compared to that prevailing in the external environment, and at most under a pressure of approximately 2 bar ;
- simultanément, on aspire par un fort courant d' air de l ' ordre de 20 à 100 litres par minute par le même terminal disposé contre ladite surface et dans lequel on crée une forte dépression statique d' au moins 2000 mm et au mieux de l'ordre de -5000 à -6500 mm ou 65 KPa de colonne d'eau et apte à extraire l'air des pores du matériau constituant la surface ,- simultaneously, we suck in a strong air flow of the order of 20 to 100 liters per minute by the same terminal placed against said surface and in which we create a strong static depression of at least 2000 mm and at best on the order of -5000 to -6500 mm or 65 KPa of water column and able to extract the air from the pores of the material constituting the surface,
- on évacue alors dans un conduit d'aspiration les gouttelettes d'eau projetée sur la surface et qui ont captées germes, bactéries et salissures qui pouvaient s'être déposés sur celle-ci et dans ses pores,- the water droplets sprayed onto the surface and which have captured germs, bacteria and dirt which may have been deposited thereon and in its pores are then discharged into a suction pipe;
- on règle le débit d' air et la dite dépression d'aspiration ainsi que la basse pression et le débit d'eau micronisée, et la température de celle- ci en fonction de la nature de la surface à mettre en hygiène, et la nature et de l'importance de sa pollution afin d'obtenir une qualité de mise en hygiène donnée sans l'endommager.- We regulate the air flow and said suction vacuum as well as the low pressure and the micronized water flow, and the temperature thereof depending on the nature of the surface to be hygienic, and the nature and importance of its pollution in order to obtain a given quality of hygiene without damaging it.
Dans un mode particulier opératoire on peut rajouter préalablement dans ladite eau propre projetée sur la surface à mettre en 97/30623 PC1YFR97/00319In a particular operating mode, it is possible to add beforehand into said clean water projected onto the surface to be 97/30623 PC1YFR97 / 00319
hygiène un produit additif désinfectant à 2 % maximum de concentration par rapport à la quantité d'eau correspondante. Ceci est géré par un ordinateur, de même pour le rajout d'un produit antimousse dans la cuve d'eau sale. L'ensemble de ces conditions opérationnelles et du dispositif suivant l' invention décrit ci-après évite tout écoulement d'eau intempestif hors du terminal, l'organe de micronisation étant contenu, même au-delà de l'effet de micronisation, dans un conduit contigu du conduit d'aspiration de l' air et se prolongeant comme ce dernier jusqu'au contact du matériau à nettoyer.hygiene a disinfectant additive product at a maximum concentration of 2% compared to the corresponding amount of water. This is managed by a computer, as is the addition of an antifoam product in the dirty water tank. All of these operational conditions and of the device according to the invention described below avoid any untimely flow of water out of the terminal, the micronization member being contained, even beyond the micronization effect, in a duct adjoining the air suction duct and extending like the latter until contact with the material to be cleaned.
On obtient de plus un séchage parfaitement réalisé en un laps de temps très court, instantané et jusqu'à 3 heures environ pour des surfaces textiles, et la dépollution du support traité effectuée en profondeur grâce à la micronisation de l 'eau qui humidifie en profondeur les pores de la matière, facilitant l 'enlèvement des particules les plus fines qu'ils retiennent, à tel point que l' on peut qualifier le résultat de " bio-propreté" .Drying is also perfectly achieved in a very short time, instantaneous and up to 3 hours approximately for textile surfaces, and the depollution of the treated support carried out in depth thanks to the micronization of the water which moistens in depth. the pores of the material, facilitating the removal of the finest particles which they retain, so much so that one can qualify the result as "bio-cleanliness".
Ce procédé permet en effet de travailler dans des locaux de classe 10, c' est-à-dire qui n' admettent pas plus de 10 particules polluantes de 0.3 micron par pied , ledit appareil ne rejetant dans l'air du local aucun germe ni particule. De plus il est possible d' obtenir une application nouvelle suivant le procédé de l'invention tel qu'on effectue grâce à celui-ci une mise en hygiène instantanée, et donc également une ultra propreté : le procédé ne laisse sur la surface traitée au maximum 10 UFC de bactéries pour 25 cm et même suivant le cas moins de 2 UFC pour 25 cm , et réduit les germes, les bactéries, les micro-organismes contenu dans et sur les pores du support d'un taux de 10 en participant à l'élimination du Biofilm (gangue de 1 à 10 microns d'épaisseur collée de façon irrémédiable sur le support), avec un indice de propreté visuel de 0 dans l'échelle de Bacharach, dont la définition est rappelée à la fin de la présente description.This process makes it possible to work in class 10 premises, that is to say which do not admit more than 10 polluting particles of 0.3 micron per foot, said apparatus not rejecting any germ or particle. In addition, it is possible to obtain a new application according to the method of the invention as it is carried out thanks to it an instant hygiene, and therefore also ultra cleanliness: the method does not leave on the surface treated with maximum 10 CFU of bacteria per 25 cm and even, as the case may be, less than 2 CFU per 25 cm, and reduces the germs, bacteria, microorganisms contained in and on the pores of the support by a rate of 10 by participating in elimination of Biofilm (gangue from 1 to 10 microns thick permanently bonded to the support), with a visual cleanliness index of 0 in the Bacharach scale, the definition of which is given at the end of this description.
L' appareil ou le dispositif suivant la présente invention, tel que décrit ci-après, peut permettre, de par sa très forte aspiration également la mise en oeuvre d'un procédé de nettoyage de surface, comme indiqué précédemment, par brouillard à haute pression, en portant la pression de micronisation de l'eau à environ 150 à 200 bar, sur parois verticales ou horizontales, la puissance de l'aspiration et l'étancheite du terminal par rapport à la surface traitée évitant toujours qu'il ne se produise des coulées d'eau hors de sa périphérie ; la température de l'eau peut être portée jusqu' à 60 degrés C et permet alors en ce cas pour certains supports de nettoyer efficacement et/ou même décaper toutes surfaces, comme pourraient dans certains cas le faire certains appareils existants à ce jour, mais avec une meilleure efficacité sans coulée d' eau et de produits.The apparatus or device according to the present invention, as described below, may allow, by its very strong suction also the implementation of a surface cleaning process, as indicated above, by high pressure mist , bringing the micronization pressure of the water to around 150 to 200 bar, on vertical or horizontal walls, the suction power and the tightness of the terminal relative to the treated surface, always preventing the flow of water outside its periphery; the temperature of the water can be brought up to 60 degrees C and then allows in this case for certain supports to clean effectively and / or even to scour all surfaces, as in certain cases could do some existing devices to date, but with better efficiency without pouring water and products.
Selon l'invention le dispositif est essentiellement caractérisé par un ensemble de moyens permettant la micronisation de l'eau à débit et à température variables, associés à des moyens produisant simultanément une très forte aspiration d'air, réglable en dépression et en débit, lesdits moyens étant simultanément contrôlés par au moins un moyen électronique central tel qu'un micro-ordinateur qui assure par l' intermédiaire d'un progiciel la régulation des débits d'eau et d'air, le tout selon un choix déterminé manuellement par l'opérateur en fonction de la nature du matériau à nettoyer, et de la nature et de l'importance de sa pollution. Il peut être prévu un nombre important de programmes automatiques permettant de traiter tous les supports tels qu'au moins 36 réglages tels que : plafonds, murs, sols, ameublements, etc, quelle que soit la nature de leur matériau tels que bois de toutes espèces, jute, textiles, crépis, marbre, thermoplastiques, terre cuite, stuc, etc..tous les paramètres étant préréglés pour chacun de ces cas grâce au dit moyen électronique central du dispositif suivant l'invention, en tenant compte de la fragilité du support et du taux d'hygiène requis et cela même jusqu' à 80 m de distance horizontale et 30 m de distance verticale.According to the invention, the device is essentially characterized by a set of means allowing the micronization of the water at variable flow rate and temperature, associated with means simultaneously producing a very strong suction of air, adjustable in depression and in flow rate, said means being simultaneously controlled by at least one central electronic means such as a microcomputer which ensures by means of a software package the regulation of the water and air flow rates, the whole according to a choice determined manually by the operator depending on the nature of the material to be cleaned, and the nature and extent of its pollution. A large number of automatic programs can be provided for processing all the supports such as at least 36 settings such as: ceilings, walls, floors, furnishings, etc., whatever the nature of their material such as wood of all kinds , jute, textiles, plaster, marble, thermoplastics, terracotta, stucco, etc. All the parameters being preset for each of these cases thanks to said central electronic means of the device according to the invention, taking into account the fragility of the support. and the required hygiene rate, even up to 80 m horizontal distance and 30 m vertical distance.
Le dispositif de mise en hygiène suivant l'invention outre les éléments cités ci-dessus, et dont certains sont connus des appareils existants, comporte suivant l'invention un moyen d' humidification de la surface de l 'objet à mettre en hygiène sous la forme d'une très fine nébulisation, émise par au moins un bec de micronisation à proximité de ladite surface, de l'eau prélevée dans un bac de stockage d'eau propre, ledit bec de micronisation étant intégré dans un dispositif terminal situé à l'extrémité d'une manche à air, de préférence souple, d'aspiration.The hygienic device according to the invention, in addition to the elements mentioned above, and some of which are known to existing devices, according to the invention comprises a means of humidifying the surface of the object to be hygienized under the form of a very fine nebulization, emitted by at least one micronization spout near said surface, of water taken from a clean water storage tank, said micronization spout being integrated in a terminal device located at the end of a windsock, preferably flexible, suction.
L'invention est en outre caractérisée par les détails qui ressortiront de la description qui va en être donnée. La figure 1 est une vue schématique montrant les différents éléments du dispositif.The invention is further characterized by the details which will emerge from the description which will be given thereof. Figure 1 is a schematic view showing the various elements of the device.
La figure 2 est une vue schématique en coupe verticale de la chambre contenant les organes assurant l 'aspiration de l 'air, associée à la chambre recevant l'eau polluée après nettoyage de la surface traitée.Figure 2 is a schematic view in vertical section of the chamber containing the organs ensuring the suction of air, associated with the chamber receiving the polluted water after cleaning the treated surface.
La figure 3 est une vue schématique en plan du clavier permettant la gestion automatique du procédé, et comportant l'écran affichant l'état des fonctions programmées.FIG. 3 is a schematic plan view of the keyboard allowing the automatic management of the process, and comprising the screen displaying the state of the programmed functions.
La figure 4 est une vue schématique du dispositif qui permet à deux employés de travailler en même temps à l' aide du même appareil central dans un même local ou dans deux locaux différents.Figure 4 is a schematic view of the device which allows two employees to work at the same time using the same central unit in the same room or in two different rooms.
La figure 5 est une vue schématique en partie écorchée, donnée à titre d'exemple, d'un terminal situé à l'extrémité de la manche à air, et qui contient l 'organe de micronisation. Selon la figure 1 le dispositif comporte le bac 1 contenant l'eau propre destinée à la micronisation et le bac 2 recevant l' eau récupérée par aspiration chargée des éléments polluants. Chacun de ces bacs comporte lui-même une sonde 3 constatant le plein du bac correspondant et une sonde 4 constatant son état vide. Lesdites sondes 4 et 3 du réservoir d'eau propre 1 contrôlent de façon coordonnée la vanne électrostatique 5 qui autorise ou arrête, selon l'ordre reçu, le remplissage dudit réservoir d' eau propre 1. En effet, l'arrivée d'eau propre raccordée au réseau est commandée par l 'ordinateur central si la cuve d'eau propre est vide ; la sonde de niveau haut arrête et ferme l 'électrovanne d'arrivée d'eau.Figure 5 is a schematic view partly broken away, given by way of example, of a terminal located at the end of the air bag, and which contains the micronization member. According to FIG. 1, the device comprises the tank 1 containing the clean water intended for micronization and the tank 2 receiving the water recovered by suction loaded with polluting elements. Each of these tanks itself comprises a probe 3 noting the fullness of the corresponding tank and a probe 4 noting its empty state. Said probes 4 and 3 of the clean water tank 1 control in a coordinated manner the electrostatic valve 5 which authorizes or stops, according to the order received, the filling of said clean water tank 1. In fact, the arrival of water clean connected to the network is controlled by the central computer if the clean water tank is empty; the high level probe stops and closes the water inlet solenoid valve.
Les sondes 3 et 4 du bac 2 de récupération de l' eau polluée contrôle aussi de façon coordonnée la motopompe 6 qui autorise ou arrête la vidange dudit bac quand celui-ci est relié à une conduite d'évacuation extérieure. L'aspiration de l' air à travers le bac 2 dans lequel débouche le tuyau souple d'aspiration extérieur 7 est obtenue au moyen de deux turbines centrifuges 8 (à étages multiples), montées en série à travers la conduite 16 afin d'atteindre une basse dépression, chacune étant animée par un moteur électrique 9, l'aspiration de la première turbine est en relation avec le bac 2 dans lequel elle provoque le vide d'air et l'échappement de la deuxième turbine étant mis à l' atmosphère à travers un tube ajusté à la sortie 54. La micronisation de l ' eau propre contenue dans le bac 1 est obtenue par la mise en pression au moyen de la pompe électrique 10 qui l 'achemine à travers la tuyauterie 12 jusqu' à l'organe 1 1 de micronisation placé à proximité de l 'extrémité de la manche à air souple d' aspiration 7. L'eau propre ainsi propulsée par l'électropompe 10 peut être portée à des températures variables toujours inférieures à la température critique supportée par le matériau devant être mise en hygiène.The probes 3 and 4 of the tank 2 for recovering polluted water also control in a coordinated manner the motor pump 6 which authorizes or stops the emptying of said tank when the latter is connected to an external evacuation pipe. The suction of air through the tank 2 into which the flexible external suction pipe 7 opens is obtained by means of two centrifugal turbines 8 (with multiple stages), connected in series through the pipe 16 in order to reach a low vacuum, each being driven by an electric motor 9, the suction of the first turbine is in relation to the tank 2 in which it causes the air vacuum and the exhaust of the second turbine being put into the atmosphere through a tube adjusted at the outlet 54. The micronization of the clean water contained in the tank 1 is obtained by pressurization by means of the electric pump 10 which conveys it through the piping 12 to the organ 1 1 of micronization placed near the end of the flexible air bag suction 7. The clean water thus propelled by the electric pump 10 can be brought to variable temperatures always lower than the critical temperature supported by the material to be hygienic.
Son échauffement s'effectue d'abord à l'intérieur de son conduit métallique 12 qui est enroulé successivement sous forme des serpentins 13 autour de chacun des moteurs 9 des turbines. L'eau ainsi préchauffée peut, si nécessaire, subir une surchauffe sous contrôle d'un thermostatIts heating takes place first inside its metal conduit 12 which is wound successively in the form of coils 13 around each of the motors 9 of the turbines. Water thus preheated can, if necessary, overheat under the control of a thermostat.
20 en traversant un corps creux 14 muni de la résistance électrique 15.20 by passing through a hollow body 14 provided with the electrical resistance 15.
Le dispositif est complété par la vanne 18 qui commande l'arrivée d' eau sous pression jusqu' à l'organe de micronisation 1 1 ; par le clapet de décharge 19, qui s ' ouvrant plus ou moins en fonction de la pression régnant dans le conduit 12 selon l'état de fermeture de la vanne 18, permet de renvoyer l'excès d'eau sous pression dans le bac 1 ; par le thermostat 20 qui régule l 'intensité de chauffage du corps de chauffeThe device is completed by the valve 18 which controls the supply of pressurized water to the micronization member 1 1; by the discharge valve 19, which more or less opens as a function of the pressure prevailing in the conduit 12 according to the closed state of the valve 18, makes it possible to return the excess water under pressure in the tank 1 ; by thermostat 20 which regulates the heating intensity of the heating body
15 ; par l'électrovanne motorisée 21 qui, en fonction d'une consigne programmée, fait plus ou moins communiquer le bac 2 avec l'atmosphère pour régler la dépression qui y règne ; par la trappe motorisée 22 qui, en fonction aussi d'une consigne programmée, règle le débit d' air aspiré par l'obturation plus ou moins importante de l'ouverture 23 du coffre 26 qui fait communiquer le bac 2 avec la première des turbines 8.15; by the motorized solenoid valve 21 which, depending on a programmed setpoint, more or less communicates the tank 2 with the atmosphere to adjust the vacuum which prevails there; by the motorized hatch 22 which, as a function also of a programmed setpoint, regulates the air flow sucked by the more or less significant closure of the opening 23 of the trunk 26 which makes the tank 2 communicate with the first of the turbines 8.
Ladite ouverture 23 est protégée par le déflecteur 51 qui évite l' aspiration par les turbines 8 des particules véhiculées par l'air pollué introduit dans le bac 2 en provenance de la manche d'aspiration 7, ainsi que l'aspiration de la condensation qui peut se produire dans ce même bac.Said opening 23 is protected by the deflector 51 which prevents the suction by the turbines 8 of the particles conveyed by the polluted air introduced into the tank 2 coming from the suction sleeve 7, as well as the suction of the condensation which can occur in this same bin.
Selon la figure 2 les organes moteurs, constitués par les moteurs 9 qui animent les turbines 8, sont contenus dans l'enceinte 24 qui contribue par elle-même à l'insonorisation à laquelle participe le silencieux 27 placé sur la tubulure 28 à travers laquelle l'air aspiré par la turbine 8 est refoulé dans l'atmosphère.According to FIG. 2, the driving members, constituted by the motors 9 which drive the turbines 8, are contained in the enclosure 24 which contributes by itself to the soundproofing in which the muffler 27 placed on the pipe 28 participates through which the air sucked by the turbine 8 is discharged into the atmosphere.
Ladite turbine 8 reçoit l'air qu'elle aspire à travers le coffre 26 dont l'ouverture est située dans le bac 2. Selon une caractéristique de ce dispositif la tubulure 28 comporte l 'ajutage conique Venturi 29 destiné à aspirer l'air de ventilation des moteurs 9 afin de contribuer à leur refroidissement ainsi qu'à rejeter hors du local en cours de nettoyage, à travers la tubulure 28 qui peut avoir une très grande longueur, les particules polluantes de toutes natures qui peuvent être émises par les moteurs 9 eux-mêmes au cours de leur fonctionnement.Said turbine 8 receives the air which it sucks through the trunk 26, the opening of which is located in the tank 2. According to a characteristic of this device, the tubing 28 comprises the conical venturi nozzle 29 intended to suck the ventilation air from the motors 9 in order to contribute to their cooling as well as to discharge out of the room being cleaned, through the tubing. 28 which can have a very long length, polluting particles of all kinds which can be emitted by the motors 9 themselves during their operation.
Le bac 2, quant à lui, outre les sondes 3 et 4, comporte une sonde de secours 30 destinée à éviter, en cas de défaillance de la sonde haute 3 , que l'eau polluée récupérée, ou la mousse qui peut surnager, ne monte jusqu'à l' ouverture 23 du tube d'aspiration 26 des turbines. A cet effet l' ordinateur par l'intermédiaire d'une petite électropompe commande à celle-ci de prélever dans un bidon antimousse 55 les 25 à 50 ml nécessaires et permet ainsi de réduire la mousse à l 'état liquide. Cette même ouverture 23 de ce tube d' aspiration 26 est coiffée d'un chapeau 52 pour éviter l'introduction directe d'eau dans ce conduit 26 lors du lavage du bac 2, son couvercle étant enlevé.The tank 2, meanwhile, in addition to the probes 3 and 4, includes an emergency probe 30 intended to prevent, in the event of failure of the high probe 3, that the polluted water recovered, or the foam which may float, does not goes up to the opening 23 of the suction tube 26 of the turbines. For this purpose the computer by means of a small electric pump commands the latter to take in an anti-foam container 55 the 25 to 50 ml necessary and thus makes it possible to reduce the foam in the liquid state. This same opening 23 of this suction tube 26 is capped with a cap 52 to prevent the direct introduction of water into this conduit 26 during the washing of the tank 2, its cover being removed.
Le renouvellement du produit désinfectant se fait à chaque remplissage d' eau propre après que la pompe de vidange à vider la cuve d'eau sale. L' antimousse est alors renouvelé dans la cuve d'eau sale automatiquement. Ce sont les sondes, de niveau haut de la cuve d'eau sale et de niveau bas de la cuve d'eau propre, qui informent l'ordinateur pour l ' ouverture des électro-pompes alimentant les produits désinfectants et antimousse, si ces produits ont été demandés préalablement pour la mise en hygiène du support plafond, mur, sol, ameublement etc.The disinfectant is renewed with each filling of clean water after the drain pump empties the dirty water tank. The antifoam is then automatically renewed in the dirty water tank. These are the sensors, high level of the dirty water tank and low level of the clean water tank, which inform the computer for the opening of the electro-pumps supplying the disinfectant and anti-foam products, if these products have been previously requested for the hygiene of the support ceiling, wall, floor, furniture etc.
Le bac 2 comporte en outre un récipient de forme générale cylindrique micro-perforé 31 qui est fixé de façon amovible au tube d' aspiration d'air 7, et qui reçoit à travers ce dernier l' eau polluée récupérée et l'air simultanément aspirés. Ledit récipient 31 constitue un filtre qui retient les particules solides contenues dans l'eau sale, qui seule le traverse et emplit le bac 2.The tank 2 further comprises a container of generally cylindrical micro-perforated shape 31 which is removably attached to the air suction tube 7, and which receives through the latter the polluted water recovered and the air simultaneously sucked . Said container 31 constitutes a filter which retains the solid particles contained in the dirty water, which alone passes through it and fills the tank 2.
Le dispositif ainsi constitué, permet de procéder à la mise en hygiène des surfaces en mettant simultanément en fonctionnement le moteur 10 pour la mise en pression de l'eau propre contenue dans le bac 1 et les moteurs 9 pour faire le vide dans le bac 2 au moyen des turbines La dépression et le débit de l'air aspiré sont automatiquement et individuellement contrôlés par électrovanne 21 et la trappe motorisée 22 et un variateur de vitesse des moteurs 9.The device thus constituted, makes it possible to carry out the hygienic treatment of the surfaces by simultaneously operating the motor 10 for pressurizing the clean water contained in the tank 1 and the motors 9 for creating the vacuum in the tank 2 by means of turbines The vacuum and the flow rate of the aspirated air are automatically and individually controlled by solenoid valve 21 and the motorized hatch 22 and a speed variator of the motors 9.
De même le débit d'eau miconisée pourra varier de 0 à 70 litres par heure par le jeu de la fermeture de la vanne 18 ; et par le jeu de la trappe 22 le débit de l'air aspiré peut lui-même varier pouvant atteindre 100 litres par seconde sous une dépression statique qui peut aller jusqu' à -5000 ou -6500 mm de colonne ou 65 KPa d'eau environ par le jeu de la vanne 21. La température de l'eau micronisée sera elle-même variable étant préchauffée dans les serpentins 13 qui enveloppent extérieurement les moteurs 9 des turbines 8 où ils récupèrent les calories produites par leur fonctionnement, assurant par le même fait leur refroidissement et la récupération économique de l'énergie qui, sans cette disposition, serait dissipée en pure perte à l'intérieur de l 'enceinte 24.Likewise, the flow of miconized water may vary from 0 to 70 liters per hour by the play in closing the valve 18; and by the play of the hatch 22 the flow rate of the sucked air can itself vary up to 100 liters per second under a static depression which can go up to -5000 or -6500 mm of column or 65 KPa of water approximately by the clearance of the valve 21. The temperature of the micronized water will itself be variable being preheated in the coils 13 which externally envelop the motors 9 of the turbines 8 where they recover the calories produced by their operation, ensuring by the same makes their cooling and the economic recovery of the energy which, without this provision, would be dissipated in pure loss inside the enclosure 24.
Dans certains cas particuliers un produit désinfectant, de type peroxyde d'hydrogène contenu dans un réservoir annexe 44 peut être dilué dans l'eau du bac 1 , sous le contrôle de l'électrovanne 45 pilotée par l 'ordinateur, de même pour l'antimousse. Chacun de ces réglages pourrait s' effectuer manuellement par une action directe sur chacun des organes de contrôle ci-dessus cités. Mais ils sont plus avantageusement effectués au moyen de un ou plusieurs microprocesseurs qui jouent le rôle de micro-ordinateur et contrôlent de façon continue chacune des fonctions selon les consignes manuellement choisies par l'opérateur en vue du résultat recherché et affichées sur l'écran à cristaux liquides 37 que comporte l'appareil ; cet écran peut afficher: le type des supports à mettre hygiène, si on rajoute du désinfectant et/ou de l' antimousse, le type de terminal suivant le nombre de buses de micronisation (toujours par rapport au type de support à traiter), la connexion maintenance, également le diagnostic de défauts éventuels, et le comptage horaire du temps de fonctionnement en vue de la révision, ainsi que l'affichage de la fiche signalétique de l'appareil (type, N° de série, version etc...)....In certain particular cases a disinfectant product, of the hydrogen peroxide type contained in an auxiliary tank 44 can be diluted in the water of the tank 1, under the control of the solenoid valve 45 controlled by the computer, likewise for the defoamer. Each of these adjustments could be carried out manually by direct action on each of the above-mentioned control members. However, they are more advantageously carried out by means of one or more microprocessors which act as a microcomputer and continuously control each of the functions according to the instructions manually chosen by the operator with a view to the desired result and displayed on the screen at liquid crystals 37 which the apparatus comprises; this screen can display: the type of media to be cleaned, if disinfectant and / or antifoam are added, the type of terminal according to the number of micronization nozzles (always relative to the type of media to be treated), maintenance connection, also the diagnosis of possible faults, and the hourly counting of the operating time for revision, as well as the display of the device's data sheet (type, serial number, version etc ... ) ....
Toutes les fonctions peuvent ainsi être automatiquement déterminées par un microprocesseur en fonction du choix fixé par l'opérateur, ce programme fixant automatiquement les paramètres (pression, température, débit de l'eau micronisée ; dépression, débit d'aspiration de l'air) correspondant aux meilleurs critères de mise en hygiène des différentes surfaces à traiter : plafonds, sols, murs, etc.. et suivant leur nature : pierre, plâtre, bois, tissus matière plastique, verre, marbre... Un deuxième microprocesseur est affecté à la logique des commandes, en fonction du programme précédemment choisi et assure par le contrôle permanent des organes correspondants la régulation de la dépression et du débit de l' air ; la régulation du débit et de la température de l'eau de micronisation ; ainsi que la régulation de la puissance absorbée, pour ne pas dépasser la puissance autorisée dans les différentes installations électriques de la clientèle, qui peuvent être limitées à 12, 16 ou 22 ampères. Les ordinateurs internes permettant grâce à une carte d' interface ou modem " intégré" et/à une prise de sortie standard de type RS232 connue, située en façade sur le panneau de commande, de se raccorder sur le réseau téléphonique. Il est possible ainsi de prélever à distance :All the functions can thus be automatically determined by a microprocessor according to the choice fixed by the operator, this program automatically fixing the parameters (pressure, temperature, flow of micronized water; vacuum, flow air intake) corresponding to the best hygiene criteria for the different surfaces to be treated: ceilings, floors, walls, etc. and depending on their nature: stone, plaster, wood, plastic fabrics, glass, marble. .. A second microprocessor is assigned to the control logic, according to the previously chosen program and ensures by permanent control of the corresponding organs the regulation of the vacuum and the air flow; regulation of the flow rate and the temperature of the micronization water; as well as the regulation of the power absorbed, so as not to exceed the power authorized in the various electrical installations of the customers, which can be limited to 12, 16 or 22 amps. Internal computers allowing, thanks to an "integrated" interface card or modem and / to a known standard RS232 output socket, located on the front panel of the control panel, to connect to the telephone network. It is thus possible to remotely collect:
- jusqu'à 500 lignes d' historique en quelques minutes (mise en marche, arrêt, disjonction, choix des programmes, défauts, utilisation antimousse, désinfectant, etc.. avec l'heure, la minute, la seconde exacte des différents états) ;- up to 500 history lines in a few minutes (switching on, off, tripping, choice of programs, faults, antifoaming, disinfectant, etc. with the hour, the minute, the exact second of the different states) ;
- par jour tous les supports traités avec les temps en minutes et les rassembler par mois sous forme de tableau.- by day all the supports treated with times in minutes and collect them by month in the form of a table.
Le programme ordinateur permet aussi :The computer program also allows:
- en cas d' arrêt, soit par arrêt volontaire de la machine ou par manque de tension, de revenir systématiquement sur le dernier support demandé afin d'éviter toute fausse manoeuvre,- in the event of stopping, either by voluntary stopping of the machine or by lack of tension, to systematically return to the last support requested in order to avoid any false maneuver,
- en position maintenance de connaître l'état de toutes les entrées et sorties, le temps de fonctionnement à la seconde près de toutes les pièces, électrovannes, pompes, turbines, sondes, électropompes etc.. et de savoir instantanément à distance l'élément incriminé si besoin est.- in the maintenance position to know the status of all inputs and outputs, the operating time to the second near all parts, solenoid valves, pumps, turbines, probes, electric pumps etc. and to instantly know the element remotely incriminated if need be.
Enfin, à coté de l'écran étanche à cristaux liquides éclairé se trouve un panneau listant l'ensemble des programmes afin d'en faciliter le choix.Finally, next to the waterproof liquid crystal display, there is a panel listing all the programs to make it easier to choose.
Les commandes nécessaires s'effectuent à partir d'un clavier 38 (fig. 3) qui présente deux touches 39 et 40 permettant l' incrémentation et la décrémentation des programmes stockés en mémoires, et de deux touches + et - (41 et 42) permettant d' accroître ou de diminuer l' intensité de chacune des valeurs automatiquement introduites par le programme (pression, débit, dépression, température) et une touche "Enter" 43 validant le programme choisi ainsi que chacune des valeurs correspondantes des différents paramètres de fonctionnement. Une touche peut permettre d' annuler toute action ou programme en cours et une lumière spécifique, de type "led" , rouge éclairant un bouton en triangle comportant un point d'exclamation peut prévenir d'un défaut éventuel qu' il faut alors aller rechercher pour le visualiser et en connaître la nature afin de le corriger. L'écran 37 informe à tout instant de l'état des paramètres de fonctionnement.The necessary commands are carried out from a keyboard 38 (fig. 3) which has two keys 39 and 40 allowing the incrementation and decrementation of the programs stored in memories, and two keys + and - (41 and 42) allowing to increase or decrease the intensity of each of the values automatically entered by the program (pressure, flow, vacuum, temperature) and an "Enter" 43 key validating the chosen program as well as each of the corresponding values of the various operating parameters. A key can be used to cancel any action or program in progress and a specific light, of the "led" type, red illuminating a triangle button with an exclamation mark can warn of a possible defect which must then be sought. to view it and know its nature in order to correct it. The screen 37 informs at all times of the state of the operating parameters.
C'est ainsi que la logique du système autorise le choix de très nombreux programmes en fonction de la nature des différents supports à traiter, ainsi que des programmes subsidiaires qui, automatiquement à l' intérieur de ceux-là, peuvent ordonner, maintenir constant ou faire varier :This is how the logic of the system authorizes the choice of very many programs according to the nature of the different media to be treated, as well as subsidiary programs which, automatically within these, can order, maintain constant or vary :
- la dépression d'air de 30 % à 100 % de sa valeur maximale, par la manoeuvre contrôlée de l'électrovanne 21 ;- the air depression from 30% to 100% of its maximum value, by the controlled operation of the solenoid valve 21;
- le débit d'air de 30 % à 100 % de sa valeur maximale, par la manoeuvre contrôlée de la trappe 21 ;- the air flow from 30% to 100% of its maximum value, by the controlled operation of the hatch 21;
- le débit de la micronisation de 0 % à 100 % de sa valeur maximale, par la manoeuvre contrôlée de l 'électrovanne 18 ;- the micronization flow from 0% to 100% of its maximum value, by the controlled operation of the solenoid valve 18;
- le débit de produit désinfectant à concurrence de 2 % est distribué dans la cuve d'eau propre après la vidange de la cuve d'eau sale par la manoeuvre contrôlée de l 'électrovanne 45 ; de même pour le produit antimousse à partir de la réserve 55 ;- the flow rate of disinfectant product up to 2% is distributed in the clean water tank after emptying the dirty water tank by the controlled operation of the solenoid valve 45; the same applies to the anti-foam product from reserve 55;
- la température de l'eau de 20 ° à 60 ° C maximum ou toute autre température maximale autorisée selon la nature du matériau traité, sous le contrôle du thermostat 20 ; - le remplissage ou le vidage de chacun des bacs 1 et 2, par l 'information alternativement transmise par les sondes 2 et 4 de chacun desdits bacs.- the water temperature from 20 ° to 60 ° C maximum or any other maximum temperature authorized depending on the nature of the material treated, under the control of thermostat 20; - the filling or emptying of each of the tanks 1 and 2, by the information alternately transmitted by the probes 2 and 4 of each of the said tanks.
Chacune des fonctions ci-dessus peut aussi être ordonnée ou modifiée par le clavier, sous contrôle du micro-ordinateur qui peut s'opposer à des ordres aberrants.Each of the above functions can also be ordered or modified by the keyboard, under the control of the microcomputer which can oppose outliers.
D'autres paramètres ne sont déterminés que manuellement, tels que la puissance électrique maximale pouvant être utilisée. D' autres fonctions enfin sont exclusivement contrôlées automatiquement par le micro-ordinateur, telles que :Other parameters are only determined manually, such as the maximum electrical power that can be used. Finally, other functions are exclusively controlled automatically by the microcomputer, such as:
- le dernier défaut qui a arrêté la machine, par un contrôle interne ; - le temps de fonctionnement, par une horloge interne, pour déterminer les périodes de révision.- the last fault which stopped the machine, by an internal check; - the operating time, by an internal clock, to determine the revision periods.
On comprend donc qu'un tel dispositif met à la disposition de l'utilisateur un procédé de mise en hygiène des surfaces facile à conduire, la totalité du choix et le suivi des fonctions étant commandés à l' aide d'un simple clavier ne comportant que quatre touches qui permettent d' agir sur la totalité des fonctions et des paramètres nécessaires pour atteindre les meilleures conditions de traitement qui sont maintenues constantes tout au long de l'opération par le seul jeu du ou des microprocesseurs qui contrôlent de façon permanente l'état des différents organes d'ajustage de pression, dépression, débits, températures, et niveaux, constituées par les électrovannes 5, 18, 19, le thermostat 20, le régulateur de pression 21 , la trappe motorisée 22 et les sondes 3 et 4 de chacun des bacs 1 et 2.It is therefore understood that such a device makes available to the user a method of hygienic surfaces easy to drive, the entire choice and monitoring of functions being controlled using a simple keyboard comprising only four keys which allow you to act on all the functions and parameters necessary to achieve the best processing conditions which are kept constant throughout the operation by the single set of microprocessors which permanently control the state of the various pressure, depression, flow, temperature and level adjustment members, constituted by the solenoid valves 5, 18, 19, the thermostat 20, the pressure regulator 21, the motorized hatch 22 and the probes 3 and 4 of each of tanks 1 and 2.
La précision et la constance de ces réglages ainsi obtenues permettent de pratiquer une "bio-propreté" , en participant à l'élimination du bio-film avec un taux de réduction des germes et des bactéries d'un facteur de 10' , en instantané (voir explication en fin de description) , et d' atteindre un indice de propreté visuel 0 dans l ' échelle de Bacharach ; ceci est du à la pénétration dans les moindres pores de la matière de la micronisation de l'eau poussée jusqu'à ne diffuser que des particules 5 à 10 microns, et associée à une dépression statique particulièrement élevée, atteignant -50000 à -65000 pascal, sous laquelle s'effectue une aspiration d'air importante en débit qui extrait du matériau, ainsi humidifié en profondeur, les particules polluantes qu'il contenait ; celle-ci sont ensuite retenues dans le filtre 31 contenu dans le bac 2, l' air rejeté au delà de cette enceinte ne contenant pas plus de 10 particules polluantes de 0.3 micron par pied , ce qui permet de travailler dans des locaux de classe 10.The precision and consistency of these settings thus obtained allow for "bio-cleanliness", by participating in the elimination of bio-film with a reduction rate of germs and bacteria by a factor of 10 ' , instantaneous (see explanation at the end of the description), and reach a visual cleanliness index 0 on the Bacharach scale; this is due to the penetration in the smallest pores of the material of the micronization of the water pushed until diffusing only particles 5 to 10 microns, and associated with a particularly high static depression, reaching -50000 to -65000 pascal , under which a large air intake is carried out which extracts from the material, thus deeply moistened, the polluting particles which it contained; these are then retained in the filter 31 contained in the tank 2, the air discharged beyond this enclosure containing no more than 10 polluting particles of 0.3 micron per foot, which makes it possible to work in class 10 premises .
L'automaticité est poussée jusqu' à assurer automatiquement, quand l'appareil est relié à des conduites d' arrivée et d' évacuation d'eau, la vidange de l'eau de récupération grâce à électropompe 6 fonctionnant sous le contrôle des sondes 3 et 4 du bac 2. Il suffira alors de retirer le filtre 31 qui aura retenu les éléments polluants solides.Automaticity is pushed to ensure automatically, when the appliance is connected to water inlet and outlet pipes, the draining of recovery water thanks to an electropump 6 operating under the control of the probes 3 and 4 from tray 2. It will then suffice to remove the filter 31 which will have retained the solid polluting elements.
Le fonctionnement en continu du dispositif est assuré grâce au dispositif venturi 29, qui contribue au refroidissement des moteurs 9, l 'économie d'énergie étant obtenue par la récupération des calories naturellement produites par les moteurs 9 des turbines 8 au cours de leur fonctionnement grâce aux serpentins 12 qui enveloppent les turbines et dans lequel circule l 'eau propre dès sa sortie du bac 1.The continuous operation of the device is ensured by the venturi device 29, which contributes to the cooling of the motors 9, the energy saving being obtained by recovering the calories naturally produced by the motors 9 of the turbines 8 during their operation by to the coils 12 which surround the turbines and in which the clean water circulates as soon as it leaves the tank 1.
Vu l'importante dépression dont on dispose à l' aspiration, le tube souple 7 qui conduit l 'air aspiré, et qui porte à son extrémité l'organe 11 de micronisation (figure 5), peut être d' une longueur suffisante pour que l' on puisse travailler à l' intérieur d'un local, l'appareil lui-même restant à l'extérieur du bâtiment. Il en est de même du tube d'évacuation placé à la sortie 54 des turbines 8 (figure 1). Et, vue sa capacité d'aspiration, le dispositif peut comporter deux équipements de micronisation-aspiration représentés par les tubes 7A et 7B de la figure 4 associés chacun à un tube distinct d'eau propre et portant chacun un terminal. Dans ce cas, selon cette figure, il est prévu que l'un quelconque de ces deux équipements peut être mis en service par le seul fait que son terminal de micronisation-aspiration qui est à son extrémité est mis en contact avec une surface à traiter.Given the large vacuum available to the suction, the flexible tube 7 which conducts the sucked air, and which carries at its end the member 11 of micronization (Figure 5), may be of sufficient length so that one can work inside a room, the device itself remaining outside the building. It is the same for the evacuation tube placed at the outlet 54 of the turbines 8 (FIG. 1). And, given its suction capacity, the device may include two micronization-suction equipment represented by the tubes 7 A and 7 B of FIG. 4 each associated with a separate tube of clean water and each carrying a terminal. In this case, according to this figure, it is provided that any of these two pieces of equipment can be put into service by the mere fact that its micronization-suction terminal which is at its end is brought into contact with a surface to be treated .
Pour cela, selon la figure 4, chacun des tubes 7A et 7B est muni à son extrémité aval située à l' intérieur du bac 2 d'un clapet motorisé 33A ou 33B asservi à un capteur de pression 32A ou 32B qui contrôle simultanément une électrovanne 34A ou 34B capable d'ouvrir ou de fermer le circuit dérivé 35A ou 35B qui shunte la turbine 8 correspondante entre son tube d'évacuation 54 et le tube d'aspiration 7A ou 7B For this, according to Figure 4, each of the tubes 7 A and 7 B is provided at its downstream end located inside the tank 2 with a motorized valve 33 A or 33 B slaved to a pressure sensor 32 A or 32 B which simultaneously controls a 34 A or 34 B solenoid valve capable of opening or closing the branch circuit 35 A or 35 B which bypasses the corresponding turbine 8 between its evacuation tube 54 and the suction tube 7 A or 7 B
Ainsi, lorsque l'extrémité de l 'un des tubes, 7A par exemple, n'est pas en contact avec une paroi à traiter, la pression qui règne à l'intérieur se trouve proche de la pression atmosphérique. Le capteur 32A commande aussitôt la fermeture du clapet motorisé 33A et simultanément provoque l'ouverture de électrovanne 34A qui recycle de l'air de refoulement vers le tube 7A en quantité suffisamment faible pour ne pas faire monter sensiblement la pression qui y règne proche de la pression atmosphérique, ce qui maintient fermé le clapet 33A, isolant ce tube 7A qui ne participe donc pas à l'action de l' appareil. Il en serait de même du tube 7B.Thus, when the end of one of the tubes, 7 A for example, is not in contact with a wall to be treated, the pressure which prevails inside is close to atmospheric pressure. The sensor 32 A immediately controls the closing of the motorized valve 33 A and simultaneously causes the opening of the solenoid valve 34 A which recycles the discharge air towards the tube 7 A in a sufficiently small quantity so as not to significantly increase the pressure therein. reigns close to atmospheric pressure, which keeps the valve 33 A closed, isolating this tube 7 A which therefore does not participate in the action of the device. It would be the same for tube 7 B.
Mais dès que le terminal de micronisation-aspiration du tube 7A par exemple est mis au contact d'une paroi à traiter, aussitôt la pression monte dans le tube 7A grâce à l' apport de l 'air provenant du refoulement des turbines à travers électrovanne 34A. Aussitôt le capteur de pression 32A s'inverse, provoquant l 'ouverture du clapet 33A et la fermeture de électrovanne 34A, assurant la mise en route immédiate de l'opération de nettoyage à travers ce tube 7A sans affecter le tube 7B qui est capable de réagir de la même manière individuellement. II est évident que chaque capteur 32 qui commande électrovanne associée 34, commande aussi électrovanne 18 qui se trouve sur le circuit de l'eau de micronisation, afin que l'automaticité de l' opération de mise en hygiène soit complète, chaque manche à air 7 comportant associée à elle un tube 47 de transport de l'eau propre. Le terminal 46 (figure 5) , auquel aboutissent de façon contiguë le manche à air 7 et le tube 47 d'arrivée d'eau qui porte lui-même le gicleur de micronisation 1 1 est maintenu, par le seul effet de la dépression régnant dans le conduit d'air 7, au contact de la surface à mettre en hygiène. L' organe de micronisation 1 1 se trouve situé à une certaine distance mais à proximité cependant de la surface à nettoyer. Le terminal 46 est aussi caractérisé par le fait que le tube 47 qui conduit l'eau pressurisée jusqu' à l' organe de micronisation 1 1 et le conduit d'air 7 sont parallèles et mitoyens à l'intérieur dudit terminal 46. Ledit tube 47 qui porte l'organe 1 1 de micronisation de l' eau à proximité de l 'extrémité du terminal 46 se poursuit au-delà dudit organe 1 1 et se continue sans interruption ni ouverture de sa paroi dans la zone 53 située au delà de cet organe jusqu'à sa propre extrémité qui se trouve dans le même plan que celle du conduit d'air 7 formant ensemble une même bouche à double conduit qui assure, lorsqu'elle est en contact avec la surface à nettoyer, une parfaite étanchéité dudit terminal par rapport à l 'extérieur, ce qui évite toute coulure intempestive hors dudit terminal. Celui-ci peut aussi porter à sa base une lèvre périphérique élastique souple 48 qui, dépassant du bord inférieur de la bouche dudit terminal, permet d'assurer cette même étanchéité sur des surfaces qui ne présentent pas une parfaite planéité.But as soon as the micronization-suction terminal of the tube 7 A for example is brought into contact with a wall to be treated, the pressure immediately rises in the tube 7 A thanks to the supply of air from the discharge of the turbines to through solenoid valve 34 A. Immediately the pressure sensor 32 A reverses, causing the opening of the valve 33 A and the closing of the solenoid valve 34 A , ensuring the immediate start of the cleaning operation through this tube 7 A without affecting the tube 7 B which is able to react in the same way individually. It is obvious that each sensor 32 which controls the associated solenoid valve 34, also controls the solenoid valve 18 which is on the micronization water circuit, so that the automaticity of the hygienic operation is complete, each air bag 7 comprising associated with it a tube 47 for transporting clean water. The terminal 46 (Figure 5), to which adjoin the air hose 7 and the water inlet tube 47 which itself carries the micronization nozzle 11 is maintained, by the sole effect of the prevailing depression in the air duct 7, in contact with the surface to be cleaned. The micronizing member 1 1 is located at a certain distance but close, however, to the surface to be cleaned. The terminal 46 is also characterized by the fact that the tube 47 which leads the pressurized water to the micronization member 11 and the air duct 7 are parallel and adjoining inside said terminal 46. Said tube 47 which carries the organ 1 1 for micronizing the water near the end of the terminal 46 continues beyond said organ 1 1 and continues without interruption or opening of its wall in the area 53 located beyond this member to its own end which is in the same plane as that of the air duct 7 together forming the same double duct mouth which ensures, when it is in contact with the surface to be cleaned, a perfect seal of said terminal relative to the outside, which avoids any untimely sagging outside said terminal. The latter can also carry at its base a flexible elastic peripheral lip 48 which, projecting from the lower edge of the mouth of said terminal, makes it possible to ensure this same tightness on surfaces which do not have perfect flatness.
La cloison intermédiaire 49 située entre les conduits 7 et 47, et qui peut atteindre le plan de la bouche du terminal, est munie à son extrémité inférieure d'une brosse 50 capable de frictionner la surface à traiter pour faciliter l'enlèvement des éléments polluants. Ladite brosse 50 peut être de forme cylindrique (non figurée) animée d'un mouvement rotatif rapide et continu dans le plan horizontal pour satisfaire aux conditions de mise en hygiène les plus ardues.The intermediate partition 49 located between the conduits 7 and 47, and which can reach the plane of the terminal mouth, is provided at its lower end of a brush 50 capable of rubbing the surface to be treated to facilitate the removal of polluting elements. Said brush 50 can be of cylindrical shape (not shown) animated by a rapid and continuous rotary movement in the horizontal plane to satisfy the most difficult hygienic conditions.
Dans ce cas ledit terminal peut aussi être muni de roulettes afin de maintenir constante sa hauteur par rapport à la surface traitée, la lèvre périphérique élastique maintenant l 'étancheite ci-dessus décrite.In this case, said terminal can also be provided with rollers in order to keep its height constant relative to the treated surface, the elastic peripheral lip maintaining the seal described above.
Un tel terminal, conservant ses mêmes caractéristiques générales, peut épouser une configuration extérieures qui lui permette de faciliter sa manipulation selon toutes les configurations de l'objet à mettre en hygiène. C'est ainsi que la périphérie de sa bouche peut présenter des formes et des dimensions très diverses, pouvant aller, à titre d'exemple seulement, de 4 cm environ à 40 cm environ, sa forme dans ce cas étant oblongue. Il peut aussi être placé à l 'extrémité d'une rallonge télescopique pour atteindre des surfaces en situation élevée.Such a terminal, retaining its same general characteristics, can adopt an external configuration which allows it to facilitate its handling according to all the configurations of the object to be hygienized. Thus the periphery of its mouth can have very diverse shapes and dimensions, which may range, by way of example only, from approximately 4 cm to approximately 40 cm, its shape in this case being oblong. It can also be placed at the end of a telescopic extension to reach surfaces in high situations.
Par son organisation et son automaticité cet appareil assure un gain de temps considérable dans sa mise en service, celle-ci consistant dans le seul choix par l'opérateur du programme correspondant à la nature de la surface à traiter, le micro-ordinateur intégré assurant la détermination des différents paramètres correspondants, ainsi que le maintien de leur constance au cours de l' opération. La mise en route ainsi simplifiée peut être précédée dans certains cas par la mise en place manuelle d'un détergent sur la surface à traiter. Alors qu'actuellement il ne faut pas moins de six opérations pour atteindre ce résultat, chacune des phases nécessitant une intervention manuelle.By its organization and its automaticity this device ensures a considerable time saving in its commissioning, this consisting in the only choice by the operator of the program corresponding to the nature of the surface to be treated, the integrated microcomputer ensuring determining the various corresponding parameters, as well as maintaining their consistency during the operation. The start-up thus simplified can be preceded in certain cases by the manual installation of a detergent on the surface to be treated. Whereas currently it takes no less than six operations to achieve this result, each of the phases requiring manual intervention.
En outre l'organisation automatique des programmes et la mise en mémoire de tous les paramètres définis par des essais préalables assurent leur cohérence, interdisant de ce fait toute erreur par suite de l'incompatibilité qui serait constatée entre les différents paramètres choisis. C'est ainsi que pour telle nature de la surface à traiter, le simple fait d'afficher ladite nature à l'écran de la machine impose et maintient toutes les conditions de pression, débit et température de l'eau, dépression et débit d'air, y compris débits éventuels des produits désinfectant et/ou antimousse, tout autre réglage que l'on voudrait imposer pour la mise en hygiène de ladite surface étant refusé par le micro-ordinateur. Alors que de telles erreurs de réglage pourraient nuire à la qualité de la mise en hygiène et même à la conservation de l' objet traité lors de l ' emploi de tout autre matériel dont les réglages manuels ne posséderaient aucun contrôle automatique de leur compatibilité.In addition, the automatic organization of the programs and the storage of all the parameters defined by prior tests ensure their consistency, thereby preventing any error as a result of the incompatibility which would be noted between the different parameters chosen. Thus for such nature of the surface to be treated, the simple fact of displaying said nature on the screen of the machine imposes and maintains all the conditions of pressure, flow and temperature of water, depression and flow d air, including possible flows of disinfectant and / or anti-foam products, any other adjustment that one would like to impose for the hygiene of said surface being refused by the microcomputer. While such adjustment errors could adversely affect the quality of hygiene and even the conservation of the object treated when using any other material whose manual adjustments have no automatic control of their compatibility.
Des essais avec un dispositif de la présente invention, utilisé suivant le procédé de micronisation d'eau suivant la présente invention ont permis de vérifier l 'objectif de celle ci à savoir d'obtenir de très bonnes qualités de " mise en hygiène" et d'ultra propreté, ou encore dit de "bio propreté" en respectant les normes hospitalières et agro¬ alimentaire : on a pu mesurer alors effectivement après de tels essais qu'on obtenait :Tests with a device of the present invention, used according to the process of micronization of water according to the present invention made it possible to verify the objective of the latter, namely to obtain very good qualities of "hygiene" and of 'ultra cleanliness, or also called "bio cleanliness" while respecting hospital and food standards: we could then effectively measure after such tests that we obtained:
- d'une part moins de 2 UFC par 25 cm alors que la norme n' impose même que 10 UFC par cm , - d'autre part le respect des normes AFNOR NFT 72150 pour le contrôle de l ' activité bactéricide, germicide, fongicide etc. imposant suivant la règle des 3x5 d'obtenir en instantané voire au bout de 5 minutes maximum une réduction du nombre de bactéries de 5 espèces données (Pseudomonas aeruginosa, Escherichia coli, Staphylococcus aureus, Enterococcus hirae, Mycobacterium smegmatis) de 5 logarithmes- on the one hand less than 2 CFU per 25 cm while the standard even imposes only 10 CFU per cm, - on the other hand compliance with AFNOR NFT 72150 standards for the control of bactericidal, germicidal, fungicidal activity etc. requiring according to the 3x5 rule to obtain instantaneously or even after 5 minutes maximum a reduction in the number of bacteria of 5 given species (Pseudomonas aeruginosa, Escherichia coli, Staphylococcus aureus, Enterococcus hirae, Mycobacterium smegmatis) of 5 logarithms
(soit pour un taux donné par exemple de 10 "innocolum" déposé sur une surface donnée, une réduction de 10 soit ramenant ledit taux à 10 )(either for a given rate for example of 10 "innocolum" deposited on a given surface, a reduction of 10 or reducing said rate to 10)
De même les contrôles de niveaux de propreté visuels ont bien permis d' obtenir l ' indice 0 sur l'échelle de Bacharach : un tel contrôle étant réalisé en passant une ouate sur le support quel qu' il soit et que l'on veut contrôler, après son nettoyage, et sur une surface de 30 cm par 30 cm sur laquelle on effectuer 8 prélèvements ; on compare alors la ouate avec laquelle on a fait les dits 8 prélèvements à une échelle de couleurs de blanc au noir, sachant que la norme interprofessionnelle de nettoyage fixe un indice de 3 pour définir un sol très propre et 5 pour le textile. Likewise, checks on visual cleanliness levels have made it possible to obtain the index 0 on the Bacharach scale: such a check being carried out by passing a wadding on the support whatever it is and which one wishes to check. , after cleaning, and on a surface of 30 cm by 30 cm from which 8 samples are taken; we then compare the wadding with which the so-called 8 samples were taken on a color scale from white to black, knowing that the interprofessional cleaning standard fixes an index of 3 to define a very clean floor and 5 for textiles.
