Description

La présente invention concerne les modules sanitaires à nettoyage automatique, c'est-à-dire des modules sanitaires qui peuvent être mis en place dans des endroits publics ou semi-publics et dont les opérations de nettoyage sont commandées de manière automatique lorsque l'utilisateur a quitté l'enceinte dudit module. On connaît en particulier des modules sanitaires dont l'usage est payant et qui constituent une unité constructive autonome qui peuvent être mis en place en tout endroit non protégé tel qu'un trottoir ou une place publique. Ces modules sanitaires de type connu sont constitués d'une enceinte fermée qui comporte une cloison délimitant deux zones, une zone d'utilisation dans laquelle pénètrent les utilisateurs et dont l'accès est généralement commandé par une porte à péage, et une zone technique interdite aux utilisateurs.The present invention relates to sanitary modules with automatic cleaning, that is to say sanitary modules which can be implemented in public or semi-public places and whose cleaning operations are controlled automatically when the user has left the enclosure of said module. We know in particular sanitary modules whose use is chargeable and which constitute an autonomous construction unit which can be set up in any unprotected place such as a sidewalk or a public place. These sanitary modules of known type consist of a closed enclosure which comprises a partition delimiting two zones, a zone of use into which the users enter and whose access is generally controlled by a toll gate, and a prohibited technical zone. to users.

Une cuvette est disposée le long de la cloison de séparation et elle est montée à rotation autour d'un axe parallèle à ladite cloison, de manière à pivoter entre une position d'utilisation dans laquelle la cuvette est sensiblement horizontale le long de ladite cloison, et une position de nettoyage dans laquelle cette cuvette est amenée verticalement après passage du travers d'une ouverture de ladite cloison, de manière à être orientée vers la zone technique qui comprend des éléments de nettoyage.A bowl is arranged along the partition and it is rotatably mounted about an axis parallel to said partition, so as to pivot between a position of use in which the bowl is substantially horizontal along said partition, and a cleaning position into which this bowl is brought vertically after passing through an opening of said partition, so as to be oriented towards the technical area which includes cleaning elements.

L'ouverture, destinée au passage de la cuvette dans sa position de nettoyage, est fermée par un volet mobile, par exemple à translation verticale; ce volet n'est pas nettoyé pendant les opérations de nettoyage et ceci constitue un inconvénient car les utilisateurs sont très pointilleux en ce qui concerne les conditions d'hygiène, et ils répugnent souvent à utiliser ces modules sanitaires lorsqu'ils ne leur semblent pas être dans un état de propreté parfait (EP-A-0242274).The opening, intended for the passage of the bowl in its cleaning position, is closed by a movable flap, for example in vertical translation; this shutter is not cleaned during the cleaning operations and this constitutes a drawback because the users are very picky with regard to the hygienic conditions, and they are often reluctant to use these sanitary modules when they do not seem to be in a perfect state of cleanliness (EP-A-0242274).

Par ailleurs, lorsque le volet mobile se soulève au début de l'opération de nettoyage, il laisse subsister un espace important permettant d'accéder à la zone technique tant que la cuvette ne se trouve pas en position définitive de nettoyage. Ceci constitue un inconvénient en ce qui concerne la sécurité, car il est toujours possible qu'un utilisateur, en particulier un enfant, réussisse à rester dans la zone d'utilisation lorsque l'opération de nettoyage a été déclenchée par la fermeture de la porte d'accès après usage du module.Furthermore, when the movable flap is raised at the start of the cleaning operation, it leaves a large space allowing access to the technical area as long as the bowl is not in the final cleaning position. This is a safety disadvantage, as it is always possible for a user, especially a child, to successfully remain in the area of use when the cleaning operation has been initiated by closing the door. access after using the module.

Dans le module sanitaire connu, le séchage consécutif au lavage de la cuvette est réalisé par aspiration, ce quine donne pas entière satisfaction; en particulier, il peut rester des gouttes d'eau sur la lunette qui constitue le siège et ceci est également mal apprécié des utilisateurs.In the known sanitary module, the drying subsequent to the washing of the bowl is carried out by suction, which is not entirely satisfactory; in particular, drops of water may remain on the seat window and this is also not appreciated by users.

Dans les modules sanitaires actuels, la zone technique occupe un volume important si bien que l'ensemble du module est relativement volumineux. Cette zone technique comprend les éléments de nettoyage et de séchage ainsi que les divers mécanismes servant au déplacement de la cuvette et éventuellement des dispositifs de nettoyage. Pour réduire le volume global du module, il est nécessaire de réduire le volume de la zone technique, et, par conséquent, de réduire au maximum l'encombrement de ses dispositifs de séchage et de ses mécanismes de déplacement.In the current sanitary modules, the technical area occupies a large volume so that the entire module is relatively bulky. This technical area includes the cleaning and drying elements as well as the various mechanisms used to move the bowl and possibly the cleaning devices. To reduce the overall volume of the module, it is necessary to reduce the volume of the technical area, and, therefore, to minimize the size of its drying devices and its movement mechanisms.

Dans les modules sanitaires connus, la cuvette pivote autour d'un axe horizontal sensiblement central de telle sorte que sa partie inférieure reste dans la zone d'utilisation pendant l'opération de nettoyage et ne peut donc être nettoyée. Or, compte tenu des exigences d'hygiène des utilisateurs, il est souhaitable de pouvoir également procéder au nettoyage de cette partie inférieure de la cuvette.In known sanitary modules, the bowl pivots about a substantially central horizontal axis so that its lower part remains in the area of use during the cleaning operation and therefore cannot be cleaned. However, taking into account the hygiene requirements of the users, it is desirable to also be able to clean this lower part of the bowl.

L'invention a pour objet un module sanitaire du type décrit dans le document EP-A-0242274 qui ne présente pas les inconvénients précités.The subject of the invention is a sanitary module of the type described in document EP-A-0242274 which does not have the aforementioned drawbacks.

Il est notamment remarquable en ce qu'il comporte un dossier mobile entre deux positions, une position d'utilisation dans laquelle ledit dossier est disposé dans une ouverture de la paroi, et une position de nettoyage dans laquelle ledit dossier est disposé verticalement au-dessus de la cuvette dans le plan de l'ouverture supérieure de cette dernière, lorsqu'elle se trouve en position de nettoyage, ledit dossier ayant subi un retournement autour d'un axe horizontal lors de son passage de la position d'utilisation à la position de nettoyage, l'axe de rotation de la cuvette étant placé du bas de celle-ci.It is particularly remarkable in that it comprises a movable backrest between two positions, a position of use in which said backrest is disposed in an opening in the wall, and a cleaning position in which said backrest is arranged vertically above of the bowl in the plane of the upper opening of the latter, when it is in the cleaning position, said back having undergone a reversal around a horizontal axis when it passes from the position of use to the position cleaning, the axis of rotation of the bowl being placed from the bottom thereof.

Grâce à cette disposition la cuvette et le dossier mobile peuvent être nettoyés et séchés simultanément. Le dossier mobile permet par ailleurs de masquer l'ouverture servant au passage de la cuvette vers la position de nettoyage.Thanks to this arrangement, the bowl and the movable backrest can be cleaned and dried simultaneously. The movable backrest also makes it possible to hide the opening used for the passage of the bowl towards the cleaning position.

Selon une autre caractéristique de l'invention, le dossier est articulé de manière à effectuer, à partir de la position d'utilisation, une première rotation autour d'un axe horizontal situé à l'arrière dudit dossier en position d'utilisation dans un plan horizontal sensiblement médian dudit dossier lorsqu'il est en position d'utilisation à une distance de ce dernier sensiblement égale à la moitié de la hauteur dudit dossier, de manière que l'arête inférieure dudit dossier reste proche de l'extrémité frontale de la cuvette pendant le mouvement de rotation de cette dernière de la position d'utilisation à la position de nettoyage pour parvenir dans une position intermédiaire ou ledit dossier est sensiblement horizontal, et une deuxième rotation autour d'un axe horizontal proche de son arête inférieure dans la position intermédiaire pour venir en position de nettoyage.According to another characteristic of the invention, the backrest is articulated so as to carry out, from the position of use, a first rotation about a horizontal axis located at the rear of said backrest in the position of use in a substantially median horizontal plane of said back when in the use position at a distance from the latter substantially equal to half the height of said back, so that the lower edge of said back remains close to the front end of the bowl during the rotational movement of the latter from the position of use to the cleaning position to reach an intermediate position where said backrest is substantially horizontal, and a second rotation around a horizontal axis close to its lower edge in the intermediate position to come into cleaning position.

Grâce à cette disposition, on exclut la possibilité d'introduire le bras ou un objet dans la zone technique; pour le cas où on arriverait cependant à introduire quelque chose dans l'interstice existant entre le dossier mobile et l'arête supérieure de la cuvette pendant le mouvement de déplacement vers la position de nettoyage, on peut prévoir également des dispositifs de sécurité stoppant les mécanismes de déplacement lorsqu'il apparaît un effort anormal.Thanks to this arrangement, the possibility of introducing the arm or an object into the technical area is excluded; in the event that it is however possible to introduce something into the gap existing between the movable backrest and the upper edge of the bowl during the movement of movement towards the cleaning position, it is also possible to provide safety devices stopping the mechanisms displacement when an abnormal effort appears.

La figure 1 représente en coupe vue de dessus, un module sanitaire selon l'invention; il est logé dans une enceinte 1 de section circulaire dont le diamètre extérieur est par exemple de 1,5 mètre. Du fait de son faible encombrement, l'unité sanitaire décrite à la figure 1 peut, par exemple, être intégrée dans un édifice de faibles dimensions tel que celui connu sous le nom de "colonne Morris". L'ensemble de l'unité sanitaire a une hauteur de 2 m, ce qui permet de faire passer ce module sanitaire sous une porte de dimensions normales de manière à pouvoir le loger dans un édifice public ou semi-public tel qu'une gare. Le module sanitaire selon l'invention peut évidemment être disposé à l'extérieur, par exemple sur un trottoir.FIG. 1 represents in section seen from above, a sanitary module according to the invention; it is housed in an enclosure 1 of circular section whose outside diameter is for example 1.5 meters. Of because of its small footprint, the sanitary unit described in Figure 1 can, for example, be integrated into a small building such as that known under the name of "Morris column". The entire sanitary unit has a height of 2 m, which allows this sanitary module to pass under a door of normal dimensions so that it can be housed in a public or semi-public building such as a station. The sanitary module according to the invention can obviously be placed outside, for example on a sidewalk.

L'enceinte 1 comporte une porte coulissante 2 qui donne accès à une zone d'utilisation 3 qui est séparée d'une zone technique 4 par une paroi 5. La cuvette est schématisée en 6 et l'on peut constater que, du fait, en particulier, de la porte coulissante 2, l'espace réservé à l'usager est très nettement suffisant.The enclosure 1 has a sliding door 2 which gives access to a use area 3 which is separated from a technical area 4 by a wall 5. The bowl is shown diagrammatically at 6 and it can be seen that, as a result, in particular, from the sliding door 2, the space reserved for the user is very clearly sufficient.

La figure 2 représente de manière schématique la partie fonctionnelle du module selon l'invention; on retrouve sur cette figure: la paroi 5, le local technique 4 et la cuvette 6. La partie supérieure de la paroi 5 est constituée par un volet 8 ouvrant vers l'intérieur de la zone d'utilisation et qui porte divers accessoires, tel qu'un lave-mains automatique 9.FIG. 2 schematically represents the functional part of the module according to the invention; we find in this figure: the wall 5, the technical room 4 and the bowl 6. The upper part of the wall 5 is constituted by a flap 8 opening towards the interior of the zone of use and which carries various accessories, such than an automatic hand basin 9.

La partie inférieure 12 de la paroi 5 comporte une ouverture centrale. Cette ouverture sert au passage de la cuvette 6 et d'un dossier mobile, non représenté sur la figure 2, disposé au-dessus de la cuvette et monté de manière à pouvoir se déplacer, de sa position d'utilisation où il se trouve au-dessus de la cuvette 6, vers une position de lavage dans laquelle il se trouve dans le compartiment 4. Le panneau inférieur 12 de la paroi 5 comporte également de part et d'autre de la cuvette, un distributeur de papier 14 et une poubelle 15.The lower part 12 of the wall 5 has a central opening. This opening is used for the passage of the bowl 6 and a movable backrest, not shown in FIG. 2, placed above the bowl and mounted so as to be able to move, from its position of use where it is located above the bowl 6, towards a washing position in which it is located in the compartment 4. The lower panel 12 of the wall 5 also comprises on either side of the bowl, a paper dispenser 14 and a dustbin 15.

La figure 3 représente, de manière schématique, les éléments actifs du module sanitaire selon l'invention, c'est-à-dire la cuvette 6 et le dossier mobile 16 en position de nettoyage; ils se trouvent dans la zone de nettoyage 4 derrière le panneau inférieur 12 de la paroi 5. On voit que l'ouverture supérieure 17 de la cuvette 6 et le dossier 16 se trouvent dans un même plan vertical deux dispositifs de nettoyage 18 et 19 sont fixés sur la paroi arrière du module sanitaire et comportent chacun un ensemble de buses de pulvérisation qui sont orientées de manière à pulvériser la surface complète du dossier 16 ou du fond de la cuvette 6, constitués chacun de deux bras opposées selon un diamètre, munis de buses de propulsion 20 à l'extrémité de chaque bras, et tournant autour d'un axe central 21, respectivement 22. Chaque dispositif de nettoyage comporte une ou plusieurs buses de pulvérisation sur son moyeu 23, à savoir une buse centrale 11 et une buse latérale 13 dans l'exemple représenté.Figure 3 shows, schematically, the active elements of the sanitary module according to the invention, that is to say the bowl 6 and the movable backrest 16 in the cleaning position; they are located in the cleaning zone 4 behind the lower panel 12 of the wall 5. It can be seen that the upper opening 17 of the bowl 6 and the backrest 16 are in the same vertical plane two cleaning devices 18 and 19 are fixed to the rear wall of the sanitary module and each comprise a set of spray nozzles which are oriented so as to spray the entire surface of the backrest 16 or of the bottom of the bowl 6, each consisting of two arms opposite according to a diameter, provided with propulsion nozzles 20 at the end of each arm, and rotating about a central axis 21, respectively 22. Each cleaning device has one or more spray nozzles on its hub 23, namely a central nozzle 11 and a nozzle lateral 13 in the example shown.

Deux buses auxiliaires 24, disposées de part et d'autre de la cuvette dans la zone de nettoyage 4, servent au nettoyage de la partie inférieure de la cuvette. Lors de l'opération de nettoyage, les deux dispositifs 18 et 19 ainsi que les buses 24 aspergent la partie utile du dossier 16 et les deux côtés de la cuvette 6. Ces ensembles de nettoyage sont alimentés en eau sous pression. Lors de l'opération de nettoyage, les deux dispositifs 18 et 19 sont entraînés en rotation autour des axes fixes 21 et 22 de manière analogue aux dispositifs de nettoyage utilisé par exemple dans les machines à laver la vaisselle. Leur rotation est commandée par la pression de l'eau envoyée dans les buses de propulsion 20.Two auxiliary nozzles 24, disposed on either side of the bowl in the cleaning zone 4, are used for cleaning the lower part of the bowl. During the cleaning operation, the two devices 18 and 19 as well as the nozzles 24 spray the useful part of the backrest 16 and the two sides of the bowl 6. These cleaning assemblies are supplied with water under pressure. During the cleaning operation, the two devices 18 and 19 are rotated around the fixed axes 21 and 22 in a similar manner to the cleaning devices used for example in dishwashing machines. Their rotation is controlled by the pressure of the water sent to the propulsion nozzles 20.

Sur cette figure 3 on peut voir également que la cuvette 6 est montée à rotation autour d'un axe horizontal 25 disposé à l'intérieur de la zone de nettoyage 4. Le dossier mobile 16 effectue, quant à lui, un double mouvement de rotation, qui sera décrit plus loin, et qui permet de présenter au dispositif de nettoyage 18 la face d'utilisation du dossier et d'éviter la possibilité d'introduction d'objets quelconques dans la zone d'utilisation 4 lors du mouvement de la position d'utilisation à la position de nettoyage.In this FIG. 3, it can also be seen that the bowl 6 is rotatably mounted about a horizontal axis 25 disposed inside the cleaning zone 4. The movable backrest 16, for its part, performs a double rotation movement , which will be described further on, and which makes it possible to present the cleaning device 18 with the use side of the backrest and avoid the possibility of introducing any objects into the use area 4 during the movement from the use position to the cleaning position.

Entre les dispositifs de nettoyage 18 et 19 et les éléments fonctionnels du module, à savoir, la cuvette 6 et le dossier 16 en position de nettoyage, il subsiste un espace vertical libre 26 destiné au passage d'un dispositif de séchage qui sera décrit plus bas.Between the cleaning devices 18 and 19 and the functional elements of the module, namely, the bowl 6 and the backrest 16 in the cleaning position, there remains a free vertical space 26 intended for the passage of a drying device which will be described more low.

La figure 4 est un schéma explicatif du mouvement respectif de l'ouverture supérieure 17 de la cuvette 6 et du dossier 16 pendant le mouvement de passage de la position d'utilisation à la position de nettoyage. Comme indiqué plus haut, la face supérieure 17 de la cuvette effectue un mouvement de rotation autour de l'axe fixe 25; ces positions successives, à partir de la position d'utilisation 17′ à la position de nettoyage 17˝, sont représentées de manière simplifiée sur la figure 4. On a représenté également le dossier 16 en position d'utilisation 16′ et en position intermédiaire 16˝, les différentes positions entre ces deux positions 16′ et 16˝ étant schématisées, en correspondance avec les positions du bord supérieur de cuvette 17 par l'arête inférieure du dossier 27.Figure 4 is an explanatory diagram of the respective movement of the upper opening 17 of the bowl 6 and the folder 16 during the movement from the use position to the cleaning position. As indicated above, the upper face 17 of the bowl performs a rotational movement around the fixed axis 25; these successive positions, from the use position 17 ′ to the cleaning position 17˝, are shown in a simplified manner in FIG. 4. The folder 16 is also shown in the use position 16 ′ and in the intermediate position 16˝, the different positions between these two positions 16 ′ and 16˝ being shown diagrammatically, in correspondence with the positions of the upper edge of the bowl 17 by the lower edge of the backrest 27.

On peut voir que les différentes positions successives de l'ouverture 17 et du bord inférieur 10 du dossier 16 sont telles qu'il existe une très faible distance entre ces deux éléments pour chaque position, cette distance peut être par exemple de 5 mm; de cette manière, pendant toute la première phase du mouvement de rotation de la cuvette et du dossier 16 vers la position de nettoyage, il n'y a pas la possibilité d'introduire des objets quelconques dans la zone de nettoyage du fait du faible espacement maintenu entre le dossier et la cuvette. Ceci est complété par un dispositif de sécurité, non représenté, par exemple électrique, qui arrête le moteur général d'entraînement de ce mouvement en cas d'effort anormal de manière à éviter tout accident pour un utilisateur qui serait resté dans le module après l'avoir utilisé; ceci suppose que cet utilisateur serait volontairement resté dans le module après avoir ouvert et refermé la porte d'accès, la fermeture de cette dernière commandant de manière automatique le processus de nettoyage.It can be seen that the different successive positions of the opening 17 and of the lower edge 10 of the backrest 16 are such that there is a very small distance between these two elements for each position, this distance can for example be 5 mm; in this way, during the entire first phase of the rotation movement of the bowl and the backrest 16 towards the cleaning position, there is no possibility of introducing any objects into the cleaning zone due to the small spacing held between the backrest and the bowl. This is supplemented by a safety device, not shown, for example electric, which stops the general motor driving this movement in the event of abnormal effort so as to avoid any accident for a user who has remained in the module after having used it; this supposes that this user would have voluntarily remained in the module after having opened and closed the access door, the closing of the latter automatically controlling the cleaning process.

Comme on peut le voir sur cette figure 4, pendant cette première phase, le dossier 16 passe de sa position d'utilisation 16′ à une position intermédiaire 16˝ où il se retrouve sensiblement horizontal après avoir effectué une rotation autour d'un axe horizontal qui est disposé dans le plan horizontal médian du dossier en position d'utilisation 16′ à une distance sensiblement égale à la moitié de la hauteur du dossier 16.As can be seen in this FIG. 4, during this first phase, the backrest 16 passes from its position of use 16 ′ to an intermediate position 16˝ where it finds itself substantially horizontal after having rotated around a horizontal axis which is arranged in the median horizontal plane of the backrest in the position of use 16 ′ at a distance substantially equal to half the height of the backrest 16.

Les figures 5 à 7 décrivent en détail le dispositif d'actionnement du dossier 16. Conformément à l'invention, tous les mouvements des parties mobiles du module selon l'invention sont commandés par un motoréducteur unique; le mouvement de passage de la position d'utilisation à la position de nettoyage et le mouvement de retour de la position de nettoyage à la position d'utilisation sont commandés par un demi-tour de ce motoréducteur qui est un moteur électrique et qui commande chacun des mouvements au moyen de cames positives, c'est-à-dire des cames rainurées dans lesquelles circule un galet relié à l'organe commandé. Plus précisément, chaque mécanisme d'entraînement comporte un levier articulé en un point fixe et comportant un galet coopérant avec une came rainurée et une biellette articulée sur ledit levier.FIGS. 5 to 7 describe in detail the device for actuating the backrest 16. According to the invention, all the movements of the mobile parts of the module according to the invention are controlled by a single geared motor; the movement from the use position to the cleaning position and the return movement from the cleaning position to the use position are controlled by a half-turn of this geared motor which is an electric motor and which controls each movements by means of positive cams, that is to say grooved cams in which circulates a roller connected to the controlled member. More specifically, each drive mechanism comprises a lever articulated at a fixed point and comprising a roller cooperating with a grooved cam and a link articulated on said lever.

Les figures 5 à 7 représentent un tel dispositif mécanique d'entraînement du dossier mobile 16. On voit sur cette figure un disque 27 qui est solidaire du moteur unique d'entraînement (non représenté) et dans lequel on a réalisé des rainures de guidage 30 d'un galet 28 qui est porté par un levier 29 monté à rotation sur un axe horizontal fixe 31 et articulé, à son extrémité, sur une biellette 32.FIGS. 5 to 7 show such a mechanical device for driving the movable backrest 16. This figure shows a disc 27 which is integral with the single drive motor (not shown) and in which guide grooves 30 of a roller 28 are produced which is carried by a lever 29 mounted for rotation on a fixed horizontal axis 31 and articulated at its end, on a link 32.

Le mouvement complet du dossier 16 se décomposant en deux mouvements de rotation successifs, il existe deux dispositifs d'entraînement du dossier 16 comportant chacun un disque rainuré, un levier et une biellette; ces deux mécanismes restent confondus pendant le premier mouvement de rotation comme on peut le voir sur les figures 5 et 6 où les deux leviers 29 et 29′ et les deux biellettes 32 et 32′ sont représentées avec une épaisseur différentes, de manière qu'on puisse les distinguer. Les deux rainures de guidage sont, bien entendu, également disposées de manière semblables pour cette première rotation. L'extrémité de la première biellette 32 est articulée sur une pièce en forme de L 33 qui est articulée autour d'un axe horizontal fixe 40 qui constitue l'axe de rotation du premier mouvement de rotation; cette pièce en L 33 est également montée à articulation sur une patte 34 solidaire de la face arrière 35 du dossier 16. Sur cette patte 34 on a fixé également à articulation un ensemble de deux bielles 36 et 37 articulées l'une sur l'autre, l'extrémité libre de la bielle 37 étant également articulée autour de l'axe fixe horizontal de rotation 34.The complete movement of the backrest 16 breaking down into two successive rotational movements, there are two drive devices for the backrest 16 each comprising a grooved disc, a lever and a link; these two mechanisms remain combined during the first rotational movement as can be seen in FIGS. 5 and 6 where the two levers 29 and 29 ′ and the two links 32 and 32 ′ are shown with different thicknesses, so that can distinguish them. The two guide grooves are, of course, also arranged similarly for this first rotation. The end of the first link 32 is articulated on an L-shaped part 33 which is articulated around a fixed horizontal axis 40 which constitutes the axis of rotation of the first rotational movement; this L-shaped part 33 is also articulated on a lug 34 secured to the rear face 35 of the backrest 16. On this lug 34 there is also fixed to articulation a set of two connecting rods 36 and 37 articulated one on the other , the free end of the connecting rod 37 also being articulated around the horizontal fixed axis of rotation 34.

Comme indiqué ci-dessus, pendant le premier mouvement de rotation, les rainures 30 et 30′ suivent des cheminements identiques et il en résulte que les leviers 29 et 29′ d'une part, et les biellettes 32 et 32′ d'autre part, restent alignées; ceci a pour conséquence que l'ensemble de la pièce en L 33 et des deux bielles 36 et 37, ne se déforme pas. Les deux rainures 30 et 30′ se rapprochant régulièrement du disque 27, les biellettes 32 et 32′ entraînant, par l'intermédiaire de la pièce en L 33 et des bielles 36 et 37, le dossier 16 en rotation autour de l'axe horizontal fixe 40 qui est disposé sensiblement dans un plan horizontal médian du dossier 16 à une distance sensiblement égale à la moitié de la hauteur dudit dossier. A la fin de ce premier mouvement de rotation, le dossier 16 se retrouve dans la position de la figure 6, c'est-à-dire sensiblement horizontalement après avoir effectué un quart de tour autour de l'axe 40, la face arrière 35 du dossier 16 se retrouvant en-dessous, et par conséquent, la face opposée d'utilisation se trouvant au-dessus, le bord inférieur 27 du dossier 16 se trouve sur la droite de la figure, c'est-à-dire près de la paroi 5 séparant la zone d'utilisation de la zone de nettoyage 4.As indicated above, during the first rotational movement, the grooves 30 and 30 ′ follow identical paths and it follows that the levers 29 and 29 ′ on the one hand, and the links 32 and 32 ′ on the other hand , remain aligned; this has the consequence that the assembly of the L-shaped part 33 and the two connecting rods 36 and 37 does not deform. The two grooves 30 and 30 ′ regularly approaching the disc 27, the links 32 and 32 ′ driving, by through the L-shaped part 33 and the connecting rods 36 and 37, the backrest 16 rotating around the fixed horizontal axis 40 which is arranged substantially in a median horizontal plane of the backrest 16 at a distance substantially equal to half of the height of said backrest. At the end of this first rotational movement, the backrest 16 is found in the position of FIG. 6, that is to say substantially horizontally after having made a quarter turn around the axis 40, the rear face 35 of the back 16 being found below, and therefore, the opposite side of use being above, the lower edge 27 of the back 16 is on the right of the figure, that is to say near the wall 5 separating the use area from the cleaning area 4.

Ce premier mouvement de rotation correspond à celui qui a été expliqué à l'aide de la figure 4; le deuxième mouvement de rotation est un mouvement qui s'effectue autour de l'axe 38 d'articulation de la pièce en L 33 sur la patte 34. La rainure 30 de guidage de l'ensemble levier 29-biellette 32 est choisie de manière que cet ensemble reste fixe; par contre, la rainure 30′ du galet 28′ de guidage du levier 29′ est conformée de manière que l'extrémité mobile du levier 29′ monte, de manière à entraîner la biellette 32′ vers le haut, ce qui entraîne les deux bielles 36 et 37 vers le haut; la bielle 37 n'est alors plus en coïncidence avec l'extrémité de la pièce en L 33 et ces différents mouvements entraînant une rotation du dossier mobile 16 de sa position intermédiaire 16˝ à sa position de nettoyage 16‴ en effectuant une rotation autour de l'axe 38 qui reste fixe pendant ce deuxième mouvement. On constate qu'à la suite de ces deux mouvements de rotation, la face avant du dossier 16 se trouve face au dispositif de nettoyage 18.This first rotational movement corresponds to that which has been explained with the aid of FIG. 4; the second rotational movement is a movement which takes place around the axis 38 of articulation of the L-shaped part 33 on the tab 34. The groove 30 for guiding the lever 29-link 32 assembly is chosen so that this set remains fixed; on the other hand, the groove 30 ′ of the roller 28 ′ for guiding the lever 29 ′ is shaped so that the movable end of the lever 29 ′ rises, so as to drive the link 32 ′ upwards, which drives the two connecting rods 36 and 37 upwards; the connecting rod 37 is then no longer coincident with the end of the L-shaped part 33 and these different movements causing the movable backrest 16 to rotate from its intermediate position 16˝ to its cleaning position 16 ‴ by rotating around the axis 38 which remains fixed during this second movement. It can be seen that following these two rotational movements, the front face of the backrest 16 is facing the cleaning device 18.

Le mouvement de rotation de la cuvette 6 est bien évidemment commandé également par un disque rainuré commandant un levier et une biellette disposés de manière similaire aux levier et biellette 29 et 32.The rotational movement of the bowl 6 is obviously also controlled by a disc grooved controlling a lever and a rod arranged similarly to the lever and rod 29 and 32.

Les figures 8 à 10 représentent le dispositif de séchage qui est monté à coulissement dans la zone 26 (voir figure 3). Ce dispositif de séchage est essentiellement constitué d'une buse plate 41 disposée verticalement; elle est alimentée par un compresseur entraîné électriquement (non représenté) disposé dans la partie supérieure de la zone de nettoyage 4; l'air fourni par ce compresseur est envoyé latéralement par un bec de soufflage latéral 42, comme on peut le voir en particulier sur la figure 9 qui est une coupe transversale de la buse 41.Figures 8 to 10 show the drying device which is slidably mounted in zone 26 (see Figure 3). This drying device essentially consists of a flat nozzle 41 arranged vertically; it is supplied by an electrically driven compressor (not shown) arranged in the upper part of the cleaning zone 4; the air supplied by this compressor is sent laterally by a lateral blowing nozzle 42, as can be seen in particular in FIG. 9 which is a cross section of the nozzle 41.

La buse de soufflage 41 est montée à coulissement sur des guides verticaux 45 et entraînée par exemple au moyen de chaînes 46 fixées en 47 sur la buse 41 et coopérant avec des roues 48 qui sont fixées sur un arbre 49 solidaire d'un moteur d'entraînement, non représenté.The blowing nozzle 41 is slidably mounted on vertical guides 45 and driven for example by means of chains 46 fixed at 47 on the nozzle 41 and cooperating with wheels 48 which are fixed on a shaft 49 secured to a motor drive, not shown.

Cette buse de soufflage réalise le séchage du dossier 16 et de la cuvette 6 par soufflage lorsqu'elle descend dans la zone 26.This blowing nozzle dries the backrest 16 and the bowl 6 by blowing when it descends into the zone 26.

Le mouvement de translation vertical de la buse de soufflage 41 s'effectue sur une grande course qui est de 75 cm selon un mode de réalisation de l'invention, et il est donc nécessaire de prévoir un conduit d'amenée de longueur réglable entre le compresseur et la buse. Selon un mode de réalisation de l'invention, cela est réalisé au moyen de quatre tubes télescopiques qui s'engagent successivement les uns sur les autres avec un jeu faible de l'ordre de 0,1 mm pour limiter les pertes, le tube le plus large étant celui qui est disposé le plus bas. Pour assurer un bon guidage des tubes l'un par rapport à l'autre, comme cela est représenté sur les figures 10 et 10a, chaque tube présente sur sa face extérieure deux rainures 55 opposées, qui coopèrent avec des têtons 56 aménagés dans la surface intérieure de chaque tube. Avantageusement, les différents tubes ont une section rectangulaire qui peut être par exemple en moyenne de 15 × 75 mm. Ces tubes peuvent être obtenus en particulier par moulage, compte tenu du fait que les rainures 65 sont ouvertes d'un côté.The vertical translational movement of the blowing nozzle 41 takes place over a large stroke which is 75 cm according to one embodiment of the invention, and it is therefore necessary to provide a supply duct of adjustable length between the compressor and nozzle. According to one embodiment of the invention, this is achieved by means of four telescopic tubes which successively engage on each other with a small clearance of the order of 0.1 mm to limit losses, the tube the wider being the one which is arranged the lowest. To ensure good guidance of the tubes relative to each other, as shown in Figures 10 and 10a, each tube has on its outer face two opposite grooves 55, which cooperate with nipples 56 arranged in the inner surface of each tube. Advantageously, the different tubes have a rectangular section which can be, for example, on average 15 × 75 mm. These tubes can be obtained in particular by molding, taking into account that the grooves 65 are open on one side.

Comme indiqué plus haut, l'ensemble des déplacements des éléments mobiles est commandé par un motoréducteur, chaque mouvement de passage de la position d'utilisation à la position de nettoyage ou inversement, correspondant à un demi-tour de ce motoréducteur; il en résulte que le cycle complet de nettoyage et de remise en position d'utilisation s'effectue sur un tour de ce moteur qui tourne toujours dans le même sens.As indicated above, all of the movements of the mobile elements is controlled by a geared motor, each movement passing from the use position to the cleaning position or vice versa, corresponding to a half-turn of this geared motor; it follows that the complete cycle of cleaning and returning to the position of use is carried out on one revolution of this motor which always rotates in the same direction.

La cuvette 6 peut avantageusement être du type décrit dans la demande de brevet français n°8605524 du 17 avril 1986 "Module sanitaire à nettoyage automatique" dans lequel l'ouverture supérieure de la cuvette est séparée en deux sections par une paroi sensiblement parallèle à la cloison de séparation des deux zones d'utilisation de nettoyage; cette paroi s'étend vers le fond de la cuvette en s'arrêtant au-dessus de ce dernier, la face supérieure de cette paroi formant la partie postérieure de la lunette. De cette manière, on réalise une section d'utilisation et une section d'évacuation dont l'ouverture communique avec une goulotte de vidange lorsque la cuvette se trouve en position de nettoyage. Cette disposition permet de donner un aspect plus classique à la lunette de manière à éviter les réticences des utilisateurs. Une telle cuvette est représentée à la figure 11.The bowl 6 can advantageously be of the type described in French patent application No. 8605524 of April 17, 1986 "Sanitary module with automatic cleaning" in which the upper opening of the bowl is separated into two sections by a wall substantially parallel to the partition separating the two areas of cleaning use; this wall extends towards the bottom of the bowl, stopping above the latter, the upper face of this wall forming the rear part of the telescope. In this way, there is provided a use section and a discharge section, the opening of which communicates with a drain chute when the bowl is in the cleaning position. This arrangement makes it possible to give a more conventional appearance to the telescope so as to avoid the reluctance of the users. Such a bowl is shown in Figure 11.

Selon l'invention, pour améliorer encore l'aspect classique de la cuvette, on prévoit un dispositif d'alimentation en eau de cette dernière; ce dispositif est actionné lors du mouvement de retour de la cuvette en position d'utilisation. De cette manière, lorsque l'usager pénètre dans le module, il trouve une cuvette qui présente un aspect tout à fait conventionnel.According to the invention, to further improve the conventional appearance of the bowl, a device for supplying water to the latter is provided; this device is activated during the return movement of the bowl in the use position. In this way, when the user enters the module, he finds a bowl which has a completely conventional appearance.

Un tel dispositif d'alimentation en eau est représenté sur la figure 11. Il est constitué par un tuyau fixe 70 dans lequel vient se placer un tuyau 71 porté par la cuvette et qui débouche dans la section d'évacuation 72 de la cuvette 6. Les deux tuyaux 70 et 71 sont disposés de telle manière que lorsque la cuvette 6 est en position d'utilisation et se trouvent alignés et leur longueur est telle qu'ils se trouvent à une très faible distance l'un de l'autre. Le tuyau 70 présente avantageusement une section intérieure plus faible que celle du tuyau 71, de manière à éviter toute perte d'eau lors de l'alimentation de la cuvette 6.Such a water supply device is shown in FIG. 11. It consists of a fixed pipe 70 in which is placed a pipe 71 carried by the bowl and which opens into the discharge section 72 of the bowl 6. The two pipes 70 and 71 are arranged in such a way that when the bowl 6 is in the use position and are aligned and their length is such that they are at a very short distance from each other. The pipe 70 advantageously has a smaller internal section than that of the pipe 71, so as to avoid any loss of water during the supply of the bowl 6.

Par ailleurs, on peut prévoir un élément chauffant dans la partie supérieure de la cuvette dont le siège fait partie intégrante de cette dernière. Avantageusement, cet élément chauffant est muni d'un thermostat de régulation de sa température.Furthermore, a heating element can be provided in the upper part of the bowl, the seat of which is an integral part of the latter. Advantageously, this heating element is provided with a thermostat for regulating its temperature.

La figure 12 représente schématiquement le dispositif de déplacement de la cuvette 6. Ce dispositif mécanique est commandé par le même disque 27 entraînant le dispositif de déplacement du dossier; ce disque comporte une rainure de guidage 81 dans laquelle se déplace un galet 82 qui est porté par un levier 83 monté à rotation sur un axe horizontal fixe 84 et articulé à son extrémité sur une biellette 85. Cette biellette 85 agit sur un levier 86 articulé autour d'un axe horizontal central 87 et qui agit sur une deuxième biellette 88 qui agit sur une pièce pivotante 89 articulée autour d'un axe fixe horizontal 91 qui agit sur deux bielles 92 et 93, cette dernière bielle 93 étant solidaire de la cuvette 6 qui pivote autour d'un axe fixe horizontal 94.FIG. 12 schematically represents the device for moving the bowl 6. This mechanical device is controlled by the same disc 27 driving the device for moving the backrest; this disc has a guide groove 81 in which a roller 82 moves which is carried by a lever 83 rotatably mounted on a fixed horizontal axis 84 and articulated at its end on a link 85. This link 85 acts on an articulated lever 86 around a central horizontal axis 87 and which acts on a second link 88 which acts on a pivoting part 89 articulated around a horizontal fixed axis 91 which acts on two connecting rods 92 and 93, the latter connecting rod 93 being integral with the bowl 6 which pivots around a horizontal fixed axis 94.

Cet ensemble cinématique est équilibré au moyen d'un dispositif de compensation 95 de telle manière que l'effort à fournir pour les mouvements de basculement aller et retour de la cuvette sont faibles.This kinematic assembly is balanced by means of a compensation device 95 in such a way that the force to be provided for the back and forth tilting movements of the bowl are low.

Selon l'invention, on prévoit un premier dispositif de sécurité contre les coincements du mouvement de basculement, ces coincements pouvant être dus à l'introduction d'une partie du corps de l'utilisateur, par exemple entre la cuvette et le dossier 16 ou par la présence d'un objet de faible poids dans la cuvette; selon un mode de réalisation, cette sécurité agit et lorsque l'effort à fournir pour le mouvement de basculement aller ou retour est supérieur à 2 à 3 kg. Cette sécurité agit dans les deux sens de basculement et entraîne l'arrêt immédiat du mouvement de basculement de l'ensemble du dossier et de la cuvette. Conformément à l'invention, on prévoit un mouvement de retour sur un angle correspondant environ à 2 à 3 degrés, de manière à permettre le décoincement, en particulier dans le cas où il s'agit d'une personne qui se serait coincé les doigts dans le mécanisme. Ce mouvement de retour est suivi d'une deuxième tentative du mouvement qui a été interrompu et s'il y a encore coincement, le mouvement est définitivement arrêté et une alarme est fournie à un dispositif central de surveillance.According to the invention, a first safety device is provided against jamming of the tilting movement, these jamming possibly being due to the introduction of a part of the user's body, for example between the bowl and the backrest 16 or by the presence of an object of low weight in the bowl; according to one embodiment, this security acts and when the effort to be provided for the outward or return tilting movement is greater than 2 to 3 kg. This safety acts in both directions of tilting and causes the immediate tilting movement of the entire backrest and the bowl. According to the invention, a return movement is provided over an angle corresponding to approximately 2 to 3 degrees, so as to allow the loosening, in particular in the case where it is a person who has trapped his fingers. in the mechanism. This return movement is followed by a second attempt of the movement which has been interrupted and if there is still jamming, the movement is definitively stopped and an alarm is supplied to a central monitoring device.

Dans le mode de réalisation de la figure 12, ce dispositif de sécurité est constitué pour chaque sens de basculement par un vérin amortisseur disposé dans une bielle de telle manière qu'il travaille à la compression, cette compression entraînant la fermeture d'un interrupteur miniature disposé dans un circuit électrique de sécurité. Pour le mouvement aller, on a disposé un tel amortisseur 96 dans la bielle 85, cet amortisseur 96 étant associé à un interrupteur miniature 97; pour le mouvement de retour vers la position d'utilisation, le dispositif de sécurité constitué par un amortisseur 98, disposé dans la bielle 88 et associé à un micro-interrupteur 99.In the embodiment of FIG. 12, this safety device is constituted for each direction of tilting by a damping cylinder arranged in a connecting rod so that it works in compression, this compression causing the closing of a miniature switch arranged in an electrical safety circuit. For the forward movement, such a damper 96 was placed in the connecting rod 85, this damper 96 being associated with a miniature switch 97; for the movement back to the position of use, the safety device consisting of a damper 98, placed in the rod 88 and associated with a microswitch 99.

Conformément à l'invention, on prévoit une sécurité supplémentaire pour le cas où il existerait un objet de volume important dans la cuvette, cet objet venant se coincer entre la cuvette et le dossier, par exemple pendant le mouvement de basculement vers la position de nettoyage. Dans l'exemple représenté sur la figure 12, ce dispositif de sécurité est constitué par un micro-interrupteur 101 qui est disposé entre le dossier 16 et la poutre 102 mobile autour de l'axe 103 qui sert à l'entraînement du dossier 16.In accordance with the invention, an additional safety device is provided in the event that there is an object of large volume in the bowl, this object coming to be wedged between the bowl and the backrest, for example during the tilting movement towards the cleaning position. . In the example shown in FIG. 12, this safety device is constituted by a microswitch 101 which is arranged between the backrest 16 and the beam 102 movable around the axis 103 which is used to drive the backrest 16.

Enfin, on prévoit une troisième sécurité pour prévenir le cas où une main, par exemple, serait introduite entre le haut du dossier 16 et la paroi de séparation 5. A cet effet, on prévoit une sorte de voûte 104 montée à rotation autour d'un axe horizontal 105 et dont l'extrémité vient presque en contact avec le haut du dossier 16 lorsque ce dernier se trouve en position d'utilisation. Un micro-interrupteur 106 est associé à cette voûte 104 de manière à détecter tous mouvements de celle-ci dus à un coïncement entre la paroi 5 et le dossier 16.Finally, a third safety device is provided to prevent the case where a hand, for example, is introduced between the top of the backrest 16 and the partition wall 5. To this end, a sort of arch 104 is mounted rotatably around. a horizontal axis 105 and the end of which almost comes into contact with the top of the backrest 16 when the latter is in the position of use. A microswitch 106 is associated with this arch 104 so as to detect any movements thereof due to a coincidence between the wall 5 and the back 16.

De toute façon, dans la réalisation pratique de ce module sanitaire, on assure que les jeux entre toutes les parties mobiles et les parties fixes soient inférieurs à 5 mm.Anyway, in the practical realization of this sanitary module, it is ensured that the clearances between all the moving parts and the fixed parts are less than 5 mm.

Enfin, on prévoit, de manière connue, un détecteur pondéral comportant deux seuils d'actionnement, par exemple de 4 et 25 kg sur un caillebotis placé autour de la cuvette 6; une dernière sécurité permet de détecter la présence d'une personne assise sur la cuvette (à partir de 2 kg) de manière à interdire la mise en route du processus de basculement en position de nettoyage.Finally, provision is made, in known manner, for a weight detector comprising two actuation thresholds, for example of 4 and 25 kg on a grating placed around the bowl 6; a final safety device makes it possible to detect the presence of a person seated on the bowl (from 2 kg) so as to prevent the start of the tilting process in the cleaning position.

On voit que l'invention permet de réaliser un module sanitaire dont l'encombrement est particulièrement réduit et qui présente un aspect classique et, en particulier, un dossier pour l'utilisateur. De plus, ce module sanitaire présente une très grande sécurité, en particulier en ce qui concerne la possibilité d'insérer des objets ou une partie du corps dans la zone de nettoyage.We see that the invention makes it possible to produce a sanitary module whose size is particularly reduced and which has a classic appearance and, in particular, a folder for the user. In addition, this sanitary module has very high security, in particular as regards the possibility of inserting objects or a part of the body into the cleaning zone.
