Description

La présente invention concerne un robinet pour lavabo, ou autre appareil sanitaire, à ouverture et fermeture automatiques, et plus particulièrement l'organe de manoeuvre d'un tel robinet.The present invention relates to a tap for a sink, or other sanitary appliance, with automatic opening and closing, and more particularly the operating member of such a tap.

On connaît déjà des robinets pourvus d'une cellule de détection à infrarouges ou à ultrasons apte à déceler la présence des mains d'un utilisateur et à transmettre l'information à un module électronique de commande programmé pour actionner une ou deux électrovannes.Valves already known are provided with an infrared or ultrasonic detection cell capable of detecting the presence of the hands of a user and of transmitting the information to an electronic control module programmed to actuate one or two solenoid valves.

Parmi ces robinets certains comportent une cellule de détection positionnée sur le corps du robinet soit à proximité de l'orifice de sortie de l'eau, soit à la base du robinet. Toutefois ces dispositifs présentent pour la plupart cet inconvénient que l'utilisateur non averti n'en comprend pas immédiatement le mode de fonctionnement, particulièrement dans le cas où il s'agit d'un robinet simple, sans mitigeur.Among these taps, some have a detection cell positioned on the tap body either near the water outlet or at the base of the tap. However, these devices have for the most part this drawback that the uninformed user does not immediately understand the operating mode, particularly in the case where it is a simple tap, without mixing valve.

La présente invention vise à remédier à ces inconvénients en proposant un dispositif adaptable à un robinet à fonctionnement automatique, de réalisation simple, dont la caractéristique essentielle réside en ce que la cellule de détection est incorporée à son organe de manoeuvre, lequel comporte en façade une fenêtre pour le passage des rayonnements nécessaires au fonctionnement de ladite cellule, par exemple des rayonnements infra-rouges.The present invention aims to remedy these drawbacks by proposing a device adaptable to a functioning tap. automatic, of simple construction, the essential characteristic of which is that the detection cell is incorporated in its operating member, which comprises on the front a window for the passage of radiation necessary for the operation of said cell, for example infrared radiation red.

A cet effet, et conformément à l'invention, la manette ou bouton de commande est prolongé par un logement adapté à contenir un corps cylindrique renfermant la cellule de détection.To this end, and in accordance with the invention, the joystick or control button is extended by a housing adapted to contain a cylindrical body enclosing the detection cell.

Selon un premier mode de réalisation de l'invention, adapté à un robinet simple non mitigeur, ledit corps cylindrique comporte à son extrémité intérieure une découpe créant une ouverture pour le passage du câble électrique servant au raccordement de la cellule de détection à un boîtier de commande d'une électrovanne assurant la distribution de l'eau.According to a first embodiment of the invention, adapted to a simple non-mixing valve, said cylindrical body comprises at its inner end a cutout creating an opening for the passage of the electric cable used for the connection of the detection cell to a control of a solenoid valve ensuring water distribution.

Dans ce mode de réalisation, l'organe de manoeuvre n'a pas d'utilité réelle en tant que tel, la distribution de l'eau se faisant automatiquement dès qu'un utilisateur avance les mains dans la direction dudit organe de manoeuvre, qui sert essentiellement à provoquer le geste dudit utilisateur.In this embodiment, the operating member has no real utility as such, the water distribution being done automatically as soon as a user advances his hands in the direction of said operating member, which essentially serves to provoke the gesture of said user.

Selon un second mode de réalisation de l'invention, adapté à un robinet mélangeur, le corps cylindrique est prolongé coaxialement par une came de mitigeage, d'un type connu en soi, à laquelle il est solidarisé et qui est abritée dans un logement adapté prolongeant le logement dudit corps cylindrique.According to a second embodiment of the invention, adapted to a mixing valve, the cylindrical body is extended coaxially by a mixing cam, of a type known per se, to which it is secured and which is housed in a suitable housing extending the housing of said cylindrical body.

Dans ce second mode de réalisation, le corps cylindrique est avantageusement solidarisé à la came de mitigeage au moyen d'une partie angulaire à section en arc de cercle dont la base prolonge ledit corps cylindrique, l'ensemble étant mobile en rotation autour de son axe.In this second embodiment, the cylindrical body is advantageously secured to the mixing cam by means of an angular part with a circular arc section, the base of which extends said cylindrical body, the assembly being movable in rotation about its axis. .

Dans ce cas, des vis positionnées judicieusement de part et d'autre de la partie angulaire permettent, en servant de butées pour ladite partie angulaire, de limiter dans les deux sens la rotation de la came de mitigeage, lesdites vis pouvant avantageusement servir au maintien en translation de la came de mitigeage et se prolonger de manière à pénétrer dans la cellule de détection en vue de l'immobiliser en rotation et ainsi éviter la détérioration de son câble d'alimentation.In this case, screws judiciously positioned on either side of the angular part make it possible, by serving as stops for said angular part, to limit the rotation of the mixing cam in both directions, said screws being able to advantageously be used for holding in translation of the mixing cam and extend so as to enter the detection cell in order to immobilize it in rotation and thus avoid deterioration of its power cable.

Dans ce second mode de réalisation, une électrovanne est disposée sur chacune des conduites d'amenée d'eau, la commande de ces électrovannes se faisant également par la cellule de détection, l'organe de manoeuvre servant uniquement à régler la température du mélange eau chaude/eau froide.In this second embodiment, a solenoid valve is arranged on each of the water supply pipes, the control of these solenoid valves also being done by the detection cell, the operating member serving only for adjusting the temperature of the water mixture. hot / cold water.

Les avantages et les caractéristiques de la présente invention ressortiront plus clairement de la description qui suit et qui se rapporte au dessin annexé, lequel en représente divers modes de réalisation non limitatifs.The advantages and characteristics of the present invention will emerge more clearly from the description which follows and which refers to the appended drawing, which represents various non-limiting embodiments.

Si on se réfère à la figure 1, on voit sur cette figure l'organe de manoeuvre fictif d'un robinet selon l'invention sans mitigeur.If we refer to Figure 1, we see in this figure the fictitious operating member of a valve according to the invention without mixing valve.

Le corps 10 du robinet comporte un perçage cylindrique 11 dans lequel est inséré un corps cylindrique 12 abritant la cellule de détection 5.The body 10 of the tap has a cylindrical bore 11 into which is inserted a cylindrical body 12 housing the detection cell 5.

Le corps cylindrique 12 est prolongé, à son extrémité interne, par une partie 13 ménageant un espace 14 entre le corps 10 du robinet et la base du corps cylindrique 12 pour le passage du câble d'alimentation 50 qui relie la cellule 5 à la commande d'une électrovanne (non représentée) placée en amont sur la conduite d'amenée d'eau 15 qui débouche à l'aval dans le bec déverseur 16.The cylindrical body 12 is extended, at its internal end, by a part 13 providing a space 14 between the body 10 of the valve and the base of the cylindrical body 12 for the passage of the supply cable 50 which connects the cell 5 to the control a solenoid valve (not shown) placed upstream on the water supply pipe 15 which opens downstream in the spout 16.

Une manette de "commande " 6 est solidarisée au corps cylindrique 12 au moyen d'une vis 60, cette manette comportant une fenêtre 61 pour le passage des rayonnements 62 émis par la cellule de détection 5.A "control" handle 6 is secured to the cylindrical body 12 by means of a screw 60, this handle comprising a window 61 for the passage of radiation 62 emitted by the detection cell 5.

Il est évident que dans ce mode de réalisation la manette de "commande" 6 n'a aucune utilité réelle en tant que telle, servant uniquement à provoquer le geste de l'utilisateur qui déclenchera la distribution de l'eau.It is obvious that in this embodiment the "control" handle 6 has no real utility as such, serving only to cause the gesture of the user which will trigger the distribution of the water.

Si on se réfère maintenant à la figure 2, on voit sur cette figure l'organe de manoeuvre d'un robinet mélangeur selon l'invention.Referring now to Figure 2, we see in this figure the operating member of a mixing valve according to the invention.

Le corps 40 du mitigeur comporte une cavité cylindrique 41 de diamètre adapté à celui du corps cylindrique 3 qui y est inséré, prolongée par une cavité 41' de diamètre adapté à celui d'une came de mitigeage 2.The body 40 of the mixer has a cylindrical cavity 41 of diameter adapted to that of the cylindrical body 3 which is inserted therein, extended by a cavity 41 'of diameter adapted to that of a mixing cam 2.

Une gorge 22 de la came 2 communique avec un canal vertical 42 partant de la cavité cylindrique 41' et débouchant dans un bec déverseur 43.A groove 22 of the cam 2 communicates with a vertical channel 42 starting from the cylindrical cavity 41 'and opening into a spout 43.

Une cellule de détection à rayons infrarouges 5 est placée dans le corps cylindrique 3 et reliée, par l'intermédiaire du câble d'alimentation 50 passant dans la queue de fixation 44, à un boîtier de commande de deux électrovannes, non représentés.An infrared ray detection cell 5 is placed in the cylindrical body 3 and connected, by means of the power cable 50 passing through the fixing tail 44, to a control unit of two solenoid valves, not shown.

Si on se réfère également à la figure 2a on peut voir que la cavité cylindrique 41' traverse partiellement, sensiblement à son extrémité, deux canaux borgnes verticaux 45 et 46 reliés à des tuyaux d'alimentation en eau, respectivement 47 pour l'eau chaude et 48 pour l'eau froide.If one also refers to FIG. 2a, it can be seen that the cylindrical cavity 41 ′ partially crosses, substantially at its end, two vertical blind channels 45 and 46 connected to water supply pipes, respectively 47 for hot water and 48 for cold water.

Une gorge excentrée partielle 20 de la came de mitigeage 2 délimite des ouvertures 45' et 46' dans les canaux 45 et 46.A partial eccentric groove 20 of the mixing cam 2 delimits openings 45 'and 46' in the channels 45 and 46.

Si on se réfère également à la figure 2b on peut voir que le maintien de la came de mitigeage 2 dans la cavité cylindrique 41' est réalisé au moyen de deux vis 31 et 32 vissées dans le corps 40 sous la cavité cylindrique 41' de part et d'autre d'une ligne verticale passant par l'axe de la came 2, et comportant chacune une collerette, respectivement 33 et 34, débordant le bord de la cavité 41', et limitant par ailleurs la rotation de la came 2 en servant de butées pour la partie angulaire 30 qui prolonge le corps cylindrique 3 à son extrémité interne, et à laquelle est solidarisée l'extrémité de la came de mitigeage 2.If we also refer to Figure 2b we can see that the maintenance of the mixing cam 2 in the cylindrical cavity 41 'is achieved by means of two screws 31 and 32 screwed into the body 40 under the cylindrical cavity 41' share and on the other side of a vertical line passing through the axis of the cam 2, and each comprising a collar, respectively 33 and 34, extending beyond the edge of the cavity 41 ′, and moreover limiting the rotation of the cam 2 in serving as stops for the angular part 30 which extends the cylindrical body 3 at its internal end, and to which the end of the mixing cam 2 is secured.

Les vis 31 et 32 comportent d'autre part des prolongements 31' et 32' insérées dans la cellule de détection 5, de manière à empêcher sa rotation et à éviter la détérioration du câble électrique 50.The screws 31 and 32 also have extensions 31 'and 32' inserted in the detection cell 5, so as to prevent its rotation and to avoid damage to the electric cable 50.

Une manette 6 de commande du mitigeage est solidarisée au corps cylindrique 3, au moyen d'une vis 60, cette manette comportant une fenêtre 61 permettant le passage des rayonnements 62.A lever 6 for controlling the mixing is secured to the cylindrical body 3, by means of a screw 60, this lever comprising a window 61 allowing the passage of radiation 62.

Lorsque l'on désire utiliser le mitigeur 4, la production d'eau est déclenchée par la cellule 5 lorsque l'utilisateur veut actionner la manette 6, du fait de l'irruption de ses mains dans le faisceau de rayons 62. Il peut alors régler la température de l'eau à sa convenance en actionnant la manette 6.When it is desired to use the mixer 4, the production of water is triggered by the cell 5 when the user wants to operate the lever 6, due to the irruption of his hands in the beam of rays 62. He can then adjust the water temperature as desired by operating the handle 6.

L'eau s'écoule, provenant des arrivées 47 et 48, jusqu'aux ouvertures 45' et 46' pratiquées dans les canaux borgnes 45 et 46. Puis selon la position de la came 2, c'est-à-dire de la gorge 20 par rapport à ces ouvertures 45' et 46', le mélange de la proportion voulue d'eau chaude et d'eau froide s'effectue dans le canal axial borgne 25 et se déverse dans la gorge périphérique 2 par l'orifice 23 pour aboutir jusqu'au bec déverseur 43, jusqu'au retrait des mains de l'utilisateur de dessous le bec déverseur 43.The water flows from the arrivals 47 and 48 to the openings 45 'and 46' made in the blind channels 45 and 46. Then depending on the position of the cam 2, that is to say from the groove 20 relative to these openings 45 'and 46', the desired proportion of hot water and cold water is mixed in the blind axial channel 25 and pours into the peripheral groove 2 through the orifice 23 to lead to the spout 43, until the user's hands are removed from below the spout 43.

Si on se réfère maintenant aux figures 3 et 3a, on voit sur ces figures un mode de réalisation d'un robinet mélangeur différent de celui représenté à la figure 2.If we now refer to FIGS. 3 and 3a, we see in these figures an embodiment of a mixing valve different from that shown in FIG. 2.

Dans ce mode de réalisation, on retrouve pour l'essentiel les mêmes pièces qu'à la figure 2, à cette différence que la sortie d'eau de la came de mitigeage 2 s'effectue à une de ses extrémités par la voie d'un canal oblique 49, une vis réglable 26 permettant de limiter la rotation de la came 2.In this embodiment, there are essentially the same parts as in FIG. 2, with the difference that the water outlet from the mixing cam 2 takes place at one of its ends by means of an oblique channel 49, an adjustable screw 26 making it possible to limit the rotation of the cam 2.

A cet effet, la vis 26 est vissée dans le corps du robinet, et son extrémité inférieure est disposée au voisinage d'un méplat 27 ménagé sur la came de mitigeage 2 : plus cette extrémité est voisine du méplat 27 moins l'ouverture 21 de la came 2 est alimentée en eau chaude.To this end, the screw 26 is screwed into the body of the tap, and its lower end is arranged in the vicinity of a flat 27 formed on the mixing cam 2: the more this end is close to the flat 27 minus the opening 21 of cam 2 is supplied with hot water.

Si on se réfère maintenant aux figures 4a et 4b, on voit sur ces figures un autre mode de réalisation d'un robinet mélangeur selon l'invention, destiné à être fixé sur un support mural et à se raccorder à des arrivées d'eau latérales.If we now refer to Figures 4a and 4b, we see in these figures another embodiment of a mixing valve according to the invention, intended to be fixed on a wall support and to be connected to lateral water inlets.

Dans ce mode de réalisation on retrouve la cellule de détection 5 logée dans un corps cylindrique 3 inséré dans une cavité 41 du corps 40 du mitigeur, le câble 50 de la cellule 5, la manette de commande 6 avec sa fenêtre 61, solidarisée au corps cylindrique 3 au moyen d'une vis 60.In this embodiment we find the detection cell 5 housed in a cylindrical body 3 inserted in a cavity 41 of the body 40 of the mixer, the cable 50 of the cell 5, the control handle 6 with its window 61, secured to the body cylindrical 3 by means of a screw 60.

La came de mitigeage 7, solidarisée au corps cylindrique 3, comporte une gorge d'entrée 71 permettant le mélange de l'eau chaude et de l'eau froide arrivant par deux conduites latérales 72, 73 et passant par un orifice 74 ménagé dans ladite gorge.The mixing cam 7, secured to the cylindrical body 3, has an inlet groove 71 allowing the mixing of hot water and cold water arriving by two lateral pipes 72, 73 and passing through an orifice 74 formed in said throat.

La came 7 comprend également une gorge 75 munie d'orifices 76, 77 de sortie de l'eau, laquelle débouche par un canal 78 dans le bec déverseur, non représenté.The cam 7 also comprises a groove 75 provided with orifices 76, 77 for leaving the water, which opens out through a channel 78 in the spout, not shown.

Il va de soi que la présente invention ne saurait être limitée à la description qui précède de certains de ses modes de réalisation, susceptibles de subir un certain nombre de modifications sans pour autant sortir du cadre de l'invention. Notamment, les modes de réalisation décrits pour des robinets de lavabo à des arrivées d'eau verticales peuvent être modifiés pour des robinets muraux ou de douche à arrivées d'eau latérales.It goes without saying that the present invention cannot be limited to the foregoing description of some of its embodiments, capable of undergoing a certain number of modifications without departing from the scope of the invention. In particular, the embodiments described for sink taps with vertical water inlets can be modified for wall or shower taps with lateral water inlets.
