Description

La présente invention concerne une installation de désinfection automatique de conduits d'écoulement d'appareils sanitaires, comportant au moins un réservoir d'une substance bactéricide liquide, au moins un diffuseur pour introduire cette substance directement ou indirectement dans lesdits conduits, une pompe alimentée pour commander ledit diffuseur et des moyens pour enclencher momentanément ladite pompe.The present invention relates to an automatic disinfection installation for the flow conduits of sanitary appliances, comprising at least one reservoir of a liquid bactericidal substance, at least one diffuser for introducing this substance directly or indirectly into said conduits, a pump supplied for controlling said diffuser and means for momentarily switching on said pump.

On connait déjà divers dispositifs de ce type destinés à assurer la désinfection des appareils sanitaires tels que des lavabos, des cuvettes de toilettes, des baignoires, notamment dans les milieux hospitaliers et/ou para-médicaux, les industries ou les laboratoires pharmaceutiques, cosmétologiques ou alimentaires.Various devices of this type are already known which are intended to disinfect sanitary devices such as sinks, toilet bowls, bathtubs, in particular in hospital and / or paramedical environments, industries or pharmaceutical, cosmetic or food.

On sait que les conduits d'écoulement et les conduits de trop-plein constituent des lieux priviligiés pour le développement d'une flore bactérienne dont la prolifération, notamment en milieu hospitalier. peut entrainer des contaminations dangereuses aux conséquences souvent graves pour les malades.It is known that the flow conduits and the overflow conduits constitute privileged places for the development of a bacterial flora, the proliferation of which, in particular in hospitals. can cause dangerous contaminations with often serious consequences for the sick.

Les précautions prises actuellement, en particulier sous forme de nettoyages réguliers et fréquents à l'eau de Javel ou à l'aide d'autres substances désinfectantes, se sont avérées insuffisantes de sorte que l'on a proposé des systèmes à distribution automatique de substances bactéricides.The precautions taken at present, in particular in the form of regular and frequent cleaning with bleach or with the aid of other disinfecting substances, have proved to be insufficient so that systems have been proposed for automatic dispensing of substances. bactericides.

Un tel dispositif est par exemple décrit par la demande de brevet français publiée sous le No 2 445 416, relative à une installation de désinfection automatique d'un dispositif d'écoulement d'un lavabo ou analogue. Cette installation comporte une bombe aérosol et un dispositif de commande équipé d'une trompe à eau qui actionne la valve de la bombe aérosol à chaque écoulement d'eau à travers le robinet du lavabo.Such a device is for example described by the French patent application published under No. 2,445,416, relating to an automatic disinfection installation of a flow device for a sink or the like. This installation comprises an aerosol can and a control device equipped with a water pump which actuates the valve of the aerosol can at each flow of water through the tap of the sink.

Ce dispositif présente divers inconvénients dus notamment à la faible capacité des bombes aérosol, à la nuisance provoquée par le gaz sous pression contenu dans ces bombes, aux dangers d'explosion que représentent ces bombes dans certains milieux industriels où la température peut atteindre, voire dépasser 50 °C, ainsi qu'au problème de montage des trompes à eau.This device has various drawbacks due in particular to the low capacity of aerosol cans, to the nuisance caused by the pressurized gas contained in these cans, to the danger of explosion represented by these cans in certain industrial environments where the temperature can reach or even exceed 50 ° C, as well as the problem of mounting the water pumps.

D'autres systèmes voisins ou similaires ont été décrits dans le brevet suisse no 292 337, le brevet britannique No 171 474 ou la demande de brevet français publiée sous le No 2 363 248.Other similar or similar systems have been described in Swiss Patent No. 292,337, British Patent No. 171,474 or the French patent application published under No. 2,363,248.

Toutefois, la plupart de ces systèmes présente des défauts, soit parce qu'il est mpossible de régler avec précision la quantité de substance batéricide injectée dans le circuit d'écoulement des eaux, soit parce çu'il est impossible de déterminer avec précision le moment auquel doit se produire cette injection pour qu'elle soit efficace.However, most of these systems have faults, either because it is impossible to precisely regulate the quantity of baticidal substance injected into the water flow circuit, or because it is impossible to determine with precision the moment to which this injection must occur for it to be effective.

La présente invention se propose de pallier l'ensemble des inconvénients mentionnés ci-dessus en réalisant un dispositif compact, facile à installer et à adapter à n'importe quel appareil sanitaire et pour lequel il est possible de déterminer avec précision à la fois la durée de la diffusion de la substance bactéricide et le moment précis de cette diffusion, de telle manière qu'elle protège efficacement les installations sanitaires contre une prolifération bactérienne dangereuse.The present invention proposes to overcome all the drawbacks mentioned above by providing a compact device, easy to install and adapt to any sanitary appliance and for which it is possible to determine with precision both the duration of the spread of the bactericidal substance and the precise time of this spread, so that it effectively protects the sanitary facilities against dangerous bacterial overgrowth.

Dans ce but, l'installation de désinfection automatique des conduits d'écoulement d'appareils sanitaires telle que définie ci-dessus est caractérisée en ce que lesdits moyens pouer enclencher momentanément ladite pompe comprennent au moins un organe détecteur agencé pour détecter l'évacuation des eaux usées par lesdits conduits desdits appareils sanitaires, et des moyens pour transmettre un signal de détection à un circuit de commande de ladite pompe d'alimentation du diffuseur.For this purpose, the automatic disinfection installation of the flow conduits of sanitary appliances as defined above is characterized in that said means for momentarily engaging said pump comprise at least one detector member arranged to detect the evacuation of waste water through said conduits of said sanitary appliances, and means for transmitting a detection signal to a control circuit of said diffuser supply pump.

Selon une forme de réalisation préférée, le circuit de commande comporte des organes de temporisation pour définir la durée d'un intervalle de temps entre la détection du début de l'évacuation des eaux usées et le début de la diffusion de la substance bactéricide. Par ailleurs, le circuit de commande comporte avantageusement des organes de temporisation pour définir la durée de la phase de diffusion de la substance bactéricide.According to a preferred embodiment, the control circuit includes timing members for defining the duration of a time interval between the detection of the start of the discharge of wastewater and the start of the spread of the bactericidal substance. Furthermore, the control circuit advantageously includes timing members for defining the duration of the diffusion phase of the bactericidal substance.

Selon une forme de réalisation particulière de la présente invention, l'organe détecteur comporte au moins un microphone et les moyens pour transmettre un signal de détection au circuit de commande de la pompe comportent au moins un amplificateur.According to a particular embodiment of the present invention, the detector member comprises at least one microphone and the means for transmitting a detection signal to the pump control circuit comprise at least one amplifier.

Toutefois, l'organe détecteur se compose de préférence d'une sonde de contact comprenant deux électrodes montées au moins partiellement à l'intérieur d'un circuit d'écoulement d'un appareil sanitaire.However, the detector member preferably consists of a contact probe comprising two electrodes mounted at least partially inside a flow circuit of a sanitary appliance.

Selon une variante, l'organe détecteur peut comporter une sonde thermique montée au moins partiellement à l'intérieur d'un circuit d'écoulement d'un appareil sanitaire, au moins une sonde de référence et les moyens pour transmettre un signal de détection au circuit de commande de la pompe d'alimentation du diffuseur peuvent comporter au moins un organe sensible à une différence de température apparaissant entre ladite sonde thermique et ladite sonde de référence.According to a variant, the detector member may comprise a thermal probe mounted at least partially inside a flow circuit of a sanitary appliance, at least one reference probe and the means for transmitting a detection signal to the control circuit of the supply pump of the diffuser may comprise at least one member sensitive to a temperature difference appearing between said thermal probe and said reference probe.

Le diffuseur est avantageusement monté de telle manière que la substance bactéricide puisse être projetée ou giclée dans les conduits d'écoulement de 1' appareil sanitaire. Le ou les gicleurs peuvent être disposés dans le conduit d'évacuation du trop-plein, à proximité d'un siphon ou même à l'intérieur du réservoir d'eau d'une cuvette de toilettes. Dans ce cas, la substance bactéricide est mélangée à l'eau de rinçage de cette cuvette.The diffuser is advantageously mounted in such a way that the bactericidal substance can be sprayed or sprayed into the flow conduits of one sanitary appliance. The sprinkler (s) can be arranged in the overflow evacuation pipe, near a siphon or even inside the water tank of a toilet bowl. In this case, the bactericidal substance is mixed with the rinsing water from this bowl.

De façon similaire, l'organe détecteur et notamment la sonde de contact, peut être montée au moins partiellement dans un conduit d'écoulement ou à l'intérieur du réservoir d'eau d'une cuvette de toilettes. Dans ce cas, il détecte une baisse de niveau dans ce réservoir.Similarly, the detector member and in particular the contact probe can be mounted at least partially in a flow conduit or inside the water tank of a toilet bowl. In this case, it detects a drop in level in this tank.

La présente invention sera mieux comprise en référence à la description d'exemples de réalisation et du dessin annexé dans lequel:

  • La figure 1 représente une vue schématique illustrant une forme de réalisation particulière de l'installation selon l'invention,
  • La figure 2 représente une vue partielle agrandie du diffuseur utilisé dans le cas de l'installation illustrée par la fig. 1,

The present invention will be better understood with reference to the description of exemplary embodiments and the attached drawing in which:
  • FIG. 1 represents a schematic view illustrating a particular embodiment of the installation according to the invention,
  • FIG. 2 represents an enlarged partial view of the diffuser used in the case of the installation illustrated in FIG. 1,

  • FIG. 4 illustrates another embodiment of the installation according to the invention, and
  • FIG. 5 represents a partial view of a variant of the installation represented by FIG. 4.

En référence à la fig. 1, l'installation représentée comporte un boîtier 1 constitué par exemple par un coffret en métal, en matière synthétique ou en tout autre matériau approprié, divisé en deux compartiments 2 et 3 par une paroi de séparation 4. Le compartiment 2 est agencé pour loger un récipient 5, par exemple un flacon en verre contenant la substance bactéricide 6. Le compartiment 3 contient avantageusement une pompe 7, un transformateur 8 abaisseur de tension pour alimenter la pompe 7, un transformateur 9 abaisseur de tension pour alimenter le ou les organes détecteurs et un circuit électronique de commande 10. La pompe 7 est raccordée au flacon 5 contenant la substance bactéricide 6 par un tube 11 dont l'extrémité libre plonge au fond du flacon 5. La pompe est par ailleurs raccordée par un conduit 12 au diffuseur 13, qui dans le présent cas est en fait un diffuseur double (illustré plus en détail par le fig. 2) destiné à injecter de la substance bactéricide à l'intérieur du conduit de trop-plein 14 d'un lavabo 15 et vers la bonde 16 de ce même lavabo. Un microphone 17 capte le bruit provoqué par l'écoulement de l'eau vers le conduit d'évacuation 18 du lavabo, et constitue l'organe détecteur alimenté par le transformateur 9 à travers la ligne 19. Cet organe détecteur transmet un signal de détection amplifié par un amplificateur 20 au circuit électronique 10 à travers la ligne 21. Le circuit électronique 10 comporte de préférence des organes de temporisation qui permettent d'une part de déterminer l'instant zéro de la diffusion de substance bactéricide, c'est-à-dire l'intervalle de temps qui s'écoule entre le début de la détection de l'écoulement des eaux usées à travers le conduit d'évacuation 18 et l'enclenchement de la pompe 7 qui alimente le diffuseur 13, et d'autre part la durée de la phase de désinfection, c'est-à-dire le temps de fonctionnement de la pompe 7.With reference to fig. 1, the installation shown comprises a box 1 consisting for example of a metal box, of synthetic material or of any other suitable material, divided into two compartments 2 and 3 by a partition wall 4. The compartment 2 is designed to accommodate a container 5, for example a glass vial containing the bactericidal substance 6. The compartment 3 advantageously contains a pump 7, a step-down transformer 8 for supplying the pump 7, a step-down transformer 9 for feeding the detector organ (s) and an electronic control circuit 10. The pump 7 is connected to the bottle 5 containing the bactericidal substance 6 by a tube 11 whose free end plunges into the bottom of the bottle 5. The pump is also connected by a conduit 12 to the diffuser 13 , which in this case is in fact a double diffuser (illustrated in more detail in FIG. 2) intended to inject bactericidal substance inside the overflow duct 14 d 'a sink 15 and towards the drain 16 of this same sink. A microphone 17 picks up the noise caused by the flow of water to the drain 18 of the sink, and constitutes the detector member supplied by the transformer 9 through the line 19. This detector organ transmits a detection signal amplified by an amplifier 20 to the electronic circuit 10 through the line 21. The electronic circuit 10 preferably comprises timing members which allow a part of determining the zero instant of the diffusion of bactericidal substance, that is to say the time interval which elapses between the start of the detection of the flow of waste water through the discharge conduit 18 and the switching on of the pump 7 which supplies the diffuser 13, and on the other hand the duration of the disinfection phase, that is to say the operating time of the pump 7.

La fig. 2 illustre plus en détail la forme particulière du diffuseur

  • 13. Il se compose de deux buses 30 et 31 raccordées à un conduit commun 32 dont l'autre extrémité est connectée à la sortie de la pompe
  • 7. Ces deux buses 30 et 31 sont destinées à gicler la substance bactéricide respectivement vers la bonde et à l'intérieur du conduit de trop-plein 14 du lavabo 15.
Fig. 2 illustrates in more detail the particular shape of the diffuser
  • 13. It consists of two nozzles 30 and 31 connected to a common conduit 32, the other end of which is connected to the outlet of the pump.
  • 7. These two nozzles 30 and 31 are intended to spray the bactericidal substance respectively towards the drain and inside the overflow pipe 14 of the sink 15.

La fig. 3 représente une variante selon laquelle une buse d'éjection de substance bactéricide 40 est montée latéralement sur le siphon 41 d'un lavabo ou de tout autre appareil sanitaire tel que baignoire, bidet, etc.... Le diffuseur 40 est sensiblement disposé dans le prolongement du conduit d'évacuation 42 de cet appareil sanitaire. Une sonde de contact 43 est fixée sur la paroi extérieure du conduit d'évacuation 42. Cette sonde comporte deux électrodes 44 et 45 qui pénètrent à l'intérieur du conduit d'évacuation 42. Au moment de l'évacuation des eaux usées, les deux électrodes 44 et 45 sont mises en court-circuit, ce qui fournit un signal de détection retransmis au circuit électronique (non représenté).Fig. 3 shows a variant according to which a bactericidal substance ejection nozzle 40 is mounted laterally on the siphon 41 of a sink or any other sanitary appliance such as a bathtub, bidet, etc. The diffuser 40 is substantially arranged in the extension of the evacuation duct 42 of this sanitary appliance. A contact probe 43 is fixed to the external wall of the discharge pipe 42. This probe has two electrodes 44 and 45 which penetrate inside the discharge pipe 42. When the wastewater is discharged, the two electrodes 44 and 45 are short-circuited, which provides a detection signal retransmitted to the electronic circuit (not shown).

La fig. 4 illustre une autre forme de réalisation de la désinfection d'une cuvette de toilettes 50 équipée d'un réservoir d'eau 51. Dans cet exemple, l'organe détecteur est constitué par une sonde de contact ou un détecteur de niveau 52 logé à l'intérieur du réservoir 51. Lorsqu'un utilisateur tire la chasse d'eau, le niveau d'eau baisse dans le réservoir 51, ce qui engendre le signal de détection capté par le circuit électronique. Un diffuseur 53 est disposé à proximité de la paroi arrière de la cuvette 50.Fig. 4 illustrates another embodiment of the disinfection of a toilet bowl 50 equipped with a water tank 51. In this example, the detector member is constituted by a contact probe or a level detector 52 housed at inside the tank 51. When a user flushes the water, the water level drops in the tank 51, which generates the detection signal picked up by the electronic circuit. A diffuser 53 is arranged near the back wall of bowl 50.

La fig. 5 illustre une variante de la réalisation décrite en référence à la fig. 4. Dans ce cas, le diffuseur 60 est logé à l'intérieur du réservoir 51 et la substance bactéricide destinée à la désinfection de la cuvette de toilettes est préalablement mélangée à l'eau de rinçage contenue dans le réservoir 51.Fig. 5 illustrates a variant of the embodiment described with reference to FIG. 4. In this case, the diffuser 60 is housed inside the tank 51 and the bactericidal substance intended for disinfecting the toilet bowl is previously mixed with the rinsing water contained in the tank 51.

Il est bien entendu que le nombre des diffuseurs ainsi que leur disposition peuvent être modifiés selon les installations. De même, le boîtier contenant le flacon de substance bactéricide et les organes de commande peuvent être équipés d'une fenêtre de détection du niveau de substance contenue dans le flacon et/ou d'une porte d'accès aux organes de commande.It is understood that the number of diffusers as well as their arrangement can be modified according to the installations. Likewise, the box containing the bottle of bactericidal substance and the control members can be equipped with a window for detecting the level of substance contained in the bottle and / or with an access door to the control members.

La présente invention n'est pas limitée aux formes de réalisation décrites et illustrées par les figures mais peut subir diverses modifications et se présenter sous diverses variantes évidentes pour l'homme de l'art.The present invention is not limited to the embodiments described and illustrated by the figures but can undergo various modifications and come in various variants obvious to those skilled in the art.
