Abstract

The invention relates to a sanitary unit having an automatic cleansing cycle. The unit comprises a lockable enclosure in which a partition defines a usage zone and a maintenance zone. A bowl is mounted for rotation between a utilization position in which it projects horizontally from the partition in said usage zone and a cleaning position in which it is tipped up into an opening in the partition so as to empty it into the maintenance zone. The upwards opening of the bowl is separated into two sections by a partition wall which extends upwardly to cooperate with the front walls of the bowl to form a rim surrounding the utilization section of the bowl. The bottom of the partition wall stops short of the base of the bowl to define an orifice and the rear section of the bowl forms an evacuation passage from the evacuation orifice rearwards to the maintenance zone when the bowl is tipped up.

Description

La présente invention concerne les modules sani- . . taires 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 peut être mise en place en tout endroit non protégé, tel qu'un trottoir ou une place publique. Ces modules sanitaires de type connu comportent une enceinte fermée qui comporte une cloison déterminant deux zones, une zone d'utilisation dans laquelle pénètre 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 . . silos with automatic cleaning, that is to say sanitary modules which can be installed 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 include a closed enclosure which comprises a partition defining two zones, a zone of use into which users enter and whose access is generally controlled by a toll gate and a technical zone prohibited 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 dans une ouverture de ladite cloison, de manière à être orientée vers la zone technique qui comprend des éléments de nettoyage. Dans ces modules sanitaires, la cuvette ne comporte aucune ouverture d'évauca- tion des déjections et la cuvette est vidée dans une goulotte d'évacuation et nettoyée lorsqu'elle se trouve en position de nettoyage, les matières qu'elle contient s'écoulant par-dessus le bord arrière de la lunette.A bowl is disposed along the partition and 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 in which this bowl is brought vertically into an opening of said partition, so as to be oriented towards the technical area which includes cleaning elements. In these sanitary modules, the bowl does not have any dump opening and the bowl is emptied into a discharge chute and cleaned when it is in the cleaning position, the materials it contains flowing over the rear edge of the telescope.

On constate une certaine réticence des usagers à utiliser ces modules sanitaires connus pour un certain nombre de raisons. Tout d'abord, la cuvette présente un aspect inhabituel qui diffère des toilettes de type connu, dans lesquelles la cuvette comporte soit un siphon d'évacuation soit une ouverture inférieure d'évacuation commandée par un volet rabattable.There is a certain reluctance of users to use these known sanitary modules for a number of reasons. First of all, the bowl has an unusual appearance which differs from the known type of toilet, in which the bowl has either a drainage siphon or a lower drainage opening controlled by a folding flap.

Les modules sanitaires à nettoyage automatique qui viennent d'être décrits sont généralement à usage public et on constate une méfiance des utilisateurs en ce qui concerne le nettoyage réalisé après chaque utilisation compte-tenu du fait que ce nettoyage s'effectue de manière automatique lorsque l'usager à quitté l'enceinte. La réticence vient du fait en particulier que l'usager ne commande pas lui-même le nettoyage et qu'il ne voit même pas comment ce nettoyage s'effectue.The sanitary modules with automatic cleaning which have just been described are generally for public use and there is a distrust of the users with regard to the cleaning carried out after each use taking into account the fact that this cleaning is carried out automatically when the user left the enclosure. The reluctance comes in particular from the fact that the user does not himself order the cleaning and that he does not even see how this cleaning is carried out.

Un autre problème réside dans le fait que le bord supérieur arrière de la cuvette constitue à la fois le déversoir des matières contenues dans la cuvette et la partie arrière de la lunette; il en résulte que ce bord arrière doit être soigneusement nettoyé, ce qui est effectivement fait, mais compte-tenu du fait que l'utilisateur ignore comment le nettoyage est réalisé, celà accroît encore sa méfiance. Ces réticences amènent généralement les usagers de tels modules sanitaires publics à les utiliser "à la turque" bien qu'il s'agisse de toilettes "à l'anglaise", l'usager voulant éviter tout contact avec la cuvette.Another problem lies in the fact that the rear upper edge of the bowl constitutes both the weir for the materials contained in the bowl and the rear part of the window; it follows that this rear edge must be carefully cleaned, which is actually done, but given the fact that the user does not know how the cleaning is carried out, this further increases his distrust. This reluctance generally leads the users of such public sanitary modules to use them "Turkish" although they are "English" toilets, the user wanting to avoid contact with the toilet.

Les opérations de nettoyage sont précédées par un mouvement de basculement de la cuvette qui présente un danger pour une personne qui se trouverait malencontreusement dans l'enceinte pendant les opérations de nettoyage; c'est pourquoi on est amené à disposer des dispositifs de sécurité complexes qui permettent de détecter la présence d'une personne dans la zone d'utilisation. Ces dispositifs de sécurité sont coûteux et de plus il est difficile de prévenir toutes les possibilités d'accidents. Par conséquent, il est souhaitable de prévoir un système de nettoyage dont le fonctionnement ne présente pas de danger par lui-même.The cleaning operations are preceded by a tilting movement of the bowl which presents a danger to a person who would unfortunately be in the enclosure during the cleaning operations; this is why we are led to have complex security devices which make it possible to detect the presence of a person in the area of use. These safety devices are expensive and moreover it is difficult to prevent all possible accidents. Therefore, it is desirable to provide a cleaning system whose operation does not present a danger by itself.

La présente invention a pour objet un module sanitaire du type qui vient d'être décrit connu par exemple de FR-A 2 496 733 et qui ne présente pas les inconvénients précités.The present invention relates to a sanitary module of the type which has just been described, known for example from FR-A 2 496 733 and which does not have the aforementioned drawbacks.

Le module sanitaire selon la présente invention est notamment remarquable en ce que l'ouverture supérieure de la cuvette est séparée en deux sections par une paroi sensiblement parallèle à la cloison précitée, s'étendant vers le fond de la cuvette en s'arrêtant au-dessus de ce dernier ; la face supérieure de cette paroi forme la partie postérieure de la lunette de manière à aménager, d'une part, une section d'utilisation, et d'autre part, une section d'évacuation dont l'ouverture vient en communication avec une goulotte de vidange lorsque la cuvette se trouve en position de nettoyage.The sanitary module according to the present invention is particularly remarkable in that the upper opening of the bowl is separated into two sections by a wall substantially parallel to the above-mentioned partition, extending towards the bottom of the bowl, stopping at the above the latter; the upper face of this wall forms the rear part of the telescope so as to provide, on the one hand, a use section, and on the other hand, a discharge section, the opening of which comes into communication with a chute when the bowl is in the cleaning position.

De cette manière, tout en maintenant une cuvette ne comportant pas d'orifice inférieur d'évacuation, on aménage deux zones, une zone d'utilisation comportant en particulier la lunette dont la partie postérieure est constituée par la paroi précitée, et une zone servant à l'évacuation des matières contenues dans la cuvette. Par ailleurs, du fait de la présence de la paroi de séparation, la cuvette présente alors un aspect évoquant les cuvettes de type connu qui sont munies d'un siphon d'évacuation.In this way, while maintaining a bowl having no lower discharge orifice, two zones are arranged, a zone of use comprising in particular the window, the rear part of which is constituted by the aforementioned wall, and a zone serving the evacuation of the materials contained in the bowl. Furthermore, due to the presence of the partition wall, the bowl then has an appearance evoking the bowls of known type which are provided with a drainage siphon.

Selon une autre caractéristique de l'invention, le module sanitaire comporte une rampe de nettoyage et de séchage qui est disposée dans la zone technique de manière à se trouver en face de la lunette lorsque la cuvette est en position de nettoyage; avantageusement, on prévoit en outre un dispositif de nettoyage qui est mobile entre deux positions, une position de repos et une position de nettoyage dans laquelle il traverse ladite rampe de nettoyage et pénètre dans la section d'utilisation de la cuvette lorsque cette dernière est en position de nettoyage. Ce dispositif de nettoyage est par exemple constitué par des pales munies de buses et entraînées en rotation par la pression du liquide qui leur est envoyé. Ceci permet de réaliser un nettoyage parfait de la lunette, en particulier du fait du séchage réalisé, ainsi que de la section d'utilisation qui est la seule visible de l'utilisateur.According to another characteristic of the invention, the sanitary module includes a cleaning and drying ramp which is arranged in the technical area so as to be in front of the window when the bowl is in the cleaning position; advantageously, a cleaning device is also provided which is movable between two positions, a rest position and a cleaning position in which it passes through said cleaning ramp and enters the section of use of the bowl when the latter is in cleaning position. This cleaning device is for example constituted by blades provided with nozzles and driven in rotation by the pressure of the liquid which is sent to them. This makes it possible to carry out a perfect cleaning of the telescope, in particular due to the drying carried out, as well as of the section of use which is the only visible of the user.

Selon encore une autre caractéristique de l'invention, l'ensemble des éléments mobiles du module sanitaire est entraîné à partir d'un seul moteur agissant sur une chaîne cinématique; un limiteur de couple est prévu en amont de la chaîne cinématique de manière à limiter les efforts exercés par les différentes éléments mobiles à un niveau tel qu'il ne puisse pas se produire d'accident, même si un utilisateur se trouve par exemple coincé dans le mouvement des différents éléments mobiles.According to yet another characteristic of the invention, all of the mobile elements of the sanitary module are driven from a single motor acting on a kinematic chain; a torque limiter is provided upstream of the kinematic chain so as to limit the forces exerted by the various moving elements to a level such that an accident cannot occur, even if a user is for example stuck in the movement of different moving elements.

Selon encore une autre caractéristique de l'invention, le cycle de nettoyage peut être déclenché par l'utilisateur de l'intérieur de la zone d'utilisation; en outre, le module sanitaire compote un dispositif d'affichage qui diffuse une information sur le déroulement du cycle de nettoyage. De cette manière, on peut vaincre toute méfiance des utilisateurs quant à l'efficacité du nettoyage puisque l'on peut le faire se dérouler devant soi et que le déroulement de ce nettoyage est exposé au moyen du dispositif d'affichage qui est par exemple disposé dans la cloison de séparation au-dessus de la cuvette. Il est évident que la possibilité de faire se dérouler le cycle de nettoyage lorsque l'utilisateur est présent dans la zone d'utilisation est rendu possible par la mesure de sécurité absolue que constitue le limiteur de couple précité.According to yet another characteristic of the invention, the cleaning cycle can be triggered by the user from inside the area of use; in addition, the sanitary module compotes a display device which disseminates information on the progress of the cleaning cycle. In this way, one can overcome any distrust of the users as for the effectiveness of the cleaning since one can make it take place in front of one and that the course of this cleaning is exposed by means of the display device which is for example arranged in the partition above the bowl. It is obvious that the possibility of running the cleaning cycle when the user is present in the area of use is made possible by the absolute safety measure that constitutes the aforementioned torque limiter.

Les figures 1 à 3 représentent un élément important de l'invention à savoir la cuvette que l'on voit également en coupe sur les figures 4 à 7. On voit en particulier sur ces figures que le fond de la cuvette 1 ne comporte pas d'orifice d'évacuation; en effet cette cuvette est dépourvue de tout orifice d'évacuation. Conformément à l'invention, son ouverture supérieure 2 est divisée en deux parties par une paroi de séparation 3 qui est perpendiculaire à l'axe de symétrie 4 de la cuvette; cette paroi de séparation s'étend à partir du niveau de l'ouverture 2 vers le fond 1 de la cuvette en s'arrêtant au-dessus de ce dernier. La face supérieure 5 de la paroi 3 constitue la partie postérieure de la lunette 6 de la cuvette sur laquelle l'usager s'assoit puisqu'il s'agit d'un module sanitaire dit "à l'anglaise".Figures 1 to 3 show an important element of the invention, namely the bowl which is also seen in section in Figures 4 to 7. It is seen in particular in these figures that the bottom of the bowl 1 does not include 'discharge opening; in fact this bowl is devoid of any discharge orifice. According to the invention, its upper opening 2 is divided into two parts by a partition wall 3 which is perpendicular to the axis of symmetry 4 of the bowl; this partition wall extends from the level of the opening 2 towards the bottom 1 of the bowl, stopping above the latter. The upper face 5 of the wall 3 constitutes the rear part of the bezel 6 of the bowl on which the user sits since it is a sanitary module called "English-style".

Comme on peut le voir en particulier sur les figures 2 à 7, la paroi de séparation 3 définit deux sections dans l'ouverture supérieure 2 de la cuvette, à savoir une section d'utilisation 7 qui est seule visible pour l'usager et une section d'évacuation 8 qui, comme on peut le voir sur les figures 4 et 6,débouche dans la zone technique 9 du module sanitaire lorsque la cuvette est en position horizontale d'utilisation et ne peut donc être vue des utilisateurs.As can be seen in particular in Figures 2 to 7, the partition wall 3 defines two sections in the upper opening 2 of the bowl, namely a section of use 7 which is only visible to the user and a discharge section 8 which, as can be seen in FIGS. 4 and 6, opens into the technical zone 9 of the sanitary module when the bowl is in the horizontal position of use and therefore cannot be seen by the users.

Comme en peut le voir sur les figures 4 à 7, la cuvette 11 est disposée dans une enceinte fermée dont l'accès est commandé par un monnayeur; cette enceinte est divisée en deux par une cloison 12 de manière à délimiter une zone d'utilisation 13 qui est seule accessible à l'usager et une zone technique 9 qui comprend en particulier l'ensemble des éléments de nettoyage avec leurs entraînements mécaniques. La cuvette 11 est disposée le long de la cloison 12, son axe de symétrie 4 étant perpendiculaire à cette dernière et, comme indiqué plus haut, seule la section d'utilisation 8 se trouve dans la zone d'utilisation 13 alors que la cuvette se trouve disposée horizontalement en position d'utilisation; la partie arrière de la cuvette 11 qui comprend en particulier la section d'évacuation 8 se trouve dans une ouverture de la cloison 12 et fait saillie dans la zone technique 9.As can be seen in Figures 4 to 7, the bowl 11 is arranged in a closed enclosure whose access is controlled by a coin mechanism; this enclosure is divided into two by a partition 12 so as to delimit a zone of use 13 which is only accessible to the user and a technical zone 9 which comprises in particular all of the cleaning elements with their mechanical drives. The bowl 11 is arranged along the partition 12, its axis of symmetry 4 being perpendicular to the latter and, as indicated above, only the use section 8 is located in the use area 13 while the bowl is located horizontally in the use position; the rear part of the bowl 11 which in particular comprises the discharge section 8 is located in an opening in the partition 12 and projects into the technical zone 9.

La cuvette 11 est mobile en rotation autour d'un axe horizontal de rotation 14 qui est parallèle à la cloison 12. Dans la première position, la position d'utilisation qui est représentée sur les figures 4 et 6, la cuvette est disposée horizontalement, c'est-à-dire que sa lunette 6 est horizontale et compte-tenu du conduit 15 qui est aménagé entre la partie arrière 16 de la cuvette et la paroi 3 et reliant la section d'évacuation 8 à l'espace libre 17 subsistant en dessous de la paroi 3, l'usager à l'impression qu'il s'agit d'une cuvette de type bien connu comportant un siphon.The bowl 11 is movable in rotation about a horizontal axis of rotation 14 which is parallel to the partition 12. In the first position, the position of use which is shown in FIGS. 4 and 6, the bowl is arranged horizontally, that is to say that its bezel 6 is horizontal and taking into account the conduit 15 which is arranged between the rear part 16 of the bowl and the wall 3 and connecting the discharge section 8 to the remaining free space 17 below the wall 3, the user has the impression that it is a well-known type of bowl comprising a siphon.

La cuvette 11 peut pivoter d'environ un quart de tour autour de l'axe 14 pour parvenir dans sa position de nettoyage qui est représentée sur les figures 5 et 7; dans cette position, la section d'évacuation 8 se trouve en communication avec une goulotte d'évaucation 18 en forme d'entonnoir qui débouche dans une canalisation 19, par exemple une canalisation d'eaux usées. Par conséquent, dans cette position, le contenu de la cuvette 11 est évacué dans la canalisation 19.The bowl 11 can pivot about a quarter of a turn around the axis 14 to reach its cleaning position which is shown in Figures 5 and 7; in this position, the discharge section 8 is in communication with a funnel-shaped discharge chute 18 which opens into a pipe 19, for example a wastewater pipe. Consequently, in this position, the content of the bowl 11 is discharged into the pipe 19.

Compte-tenu du fait qu'il n'existe pas de siphon, on prévoit un clapet 21 qui vient fermer la communication entre le conduit 19 et la goulotte 18 lorsque la cuvette se trouve en position d'utilisation (figs.4 et 6) afin d'éviter la propagation d'odeurs provenant de la canalisation 19. Un mécanisme qui sera décrit plus loin permet d'ouvrir ce clapet 21 lorsque la cuvette se trouve en position de nettoyage comme représentée sur les figures 5 et 7.In view of the fact that there is no siphon, a valve 21 is provided which closes the communication between the conduit 19 and the chute 18 when the bowl is in the position of use (figs. 4 and 6) in order to avoid the propagation of odors coming from the pipe 19. A mechanism which will be described later makes it possible to open this valve 21 when the bowl is in the cleaning position as shown in FIGS. 5 and 7.

Dans la zone technique 9, il est prévu une rampe de lavage et de séchage 22 qui est sensiblement circulaire, sa forme correspondant à la forme de la lunette 6. Cette rampe de nettoyage 22 est disposée dans la zone technique de telle manière qu'elle soit en regard de la lunette 6 lorsque la cuvette 11 se trouve en position de nettoyage. Cette rampe est munie de buses de pulvérisation qui sont destinées à pulvériser sur la lunette 6 des produits liquides de nettoyage et de désinfection. Cette rampe 22 comporte en outre un dispositif de séchage de la lunette, ce dispositif pouvant avantageusement utiliser les mêmes buses que pour le nettoyage. Selon une variante de réalisation de l'invention, le séchage peut s'effectuer par aspiration au lieu de soufflage d'air.In the technical zone 9, a washing and drying ramp 22 is provided which is substantially circular, its shape corresponding to the shape of the bezel 6. This cleaning ramp 22 is arranged in the technical zone so that it either opposite the bezel 6 when the bowl 11 is in the cleaning position. This ramp is provided with spray nozzles which are intended to spray on the telescope 6 liquid cleaning and disinfection products. This ramp 22 further comprises a device for drying the telescope, this device which can advantageously use the same nozzles as for cleaning. According to an alternative embodiment of the invention, the drying can be carried out by suction instead of air blowing.

Comme on peut le voir sur les figures 6 et 7, la cloison 12 comporte une ouverture 23 qui est dispo- sée au-dessus de la cuvette lorsque celle-ci est en position d'utilisation; cette ouverture 23 sert au passage de la partie avant 25 de la cuvette lorsque celle-ci pivote pour venir en position de nettoyage et elle est normalement fermée par un volet 24 qui s'efface lors du mouvement de rotation. Dans l'exemple représenté, ce volet est mobile en translation verticalement le long de la cloison 12 pour venir dans la position représentée à la figure 7; ce mouvement de translation est obtenu par un mécanisme qui sera décrit plus bas.As can be seen in Figures 6 and 7, the partition 12 has an opening 23 which is arranged above the bowl when the latter is in the position of use; this opening 23 is used for the passage of the front part 25 of the bowl when the latter pivots to come into the cleaning position and it is normally closed by a flap 24 which disappears during the rotational movement. In the example shown, this flap is movable in translation vertically along the partition 12 to come into the position shown in Figure 7; this translational movement is obtained by a mechanism which will be described below.

Comme on peut le voir sur les figures 6 et 7 un dispositif de nettoyage 26 est disposé dans la zone technique 9 lorsque la cuvette se trouve en position d'utilisation et vient traverser la rampe 22 pour pénétrer dans la section d'utilisation 7 de la cuvette lorsque celle-ci est en position de nettoyage. Ce dispositif de nettoyage 26 est avantageusement constitué de deux pales 27 montées à rotation sur un bras support 29 et munies de buses de pulvérisation. Des pales de ce type sont utilisées par exemple dans les machines à laver la vaiselle et leur rotation est commandée par la pression d'eau envoyée dans les buses de nettoyage. Le mécanisme de déplacement du bras 29 sera décrit plus bas.As can be seen in FIGS. 6 and 7, a cleaning device 26 is placed in the technical zone 9 when the bowl is in the use position and comes through the ramp 22 to enter the use section 7 of the bowl when it is in the cleaning position. This cleaning device 26 advantageously consists of two blades 27 rotatably mounted on a support arm 29 and provided with spray nozzles. Blades of this type are used for example in dishwashing machines and their rotation is controlled by the water pressure sent into the cleaning nozzles. The movement mechanism of the arm 29 will be described below.

Comme on peut voir sur les figures 4 et 5, on peut prévoir avantageusement une rampe de lavage 31 qui est disposée le long de la paroi interne de la goulotte 18 et qui est destinée au nettoyage de cette dernière.As can be seen in Figures 4 and 5, one can advantageously provide a washing ramp 31 which is arranged along the internal wall of the chute 18 and which is intended for cleaning the latter.

Le fonctionnement des différents dispositifs qui viennent d'être décrits a été représenté schématiquement sur les deux séries de figures 4 et 5 d'une part et 6 et 7 d'autre part pour des raisons de clarté. Lorsque la cuvette 11 se trouve en position d'utilisation, le clapet 21 ferme la communication entre la goulotte 18 et la canalisation 19, le volet 24 se trouve en position de fermeture (fig.6) et le dispositif de nettoyage se trouve dans la zone technique 9 (fig.6). Lorsque la cuvette pivote pour venir en position de nettoyage, le volet 24 coulisse vers le haut, le clapet 21 s'ouvre et le dispositif de nettoyage 26 pénètre dans la section d'utilisation 7 de la cuvette 11. Les rampes 22 et 31 sont mises en action ainsi que le dispositif de nettoyage 26; on obtient donc un effet de nettoyage dans la section d'utilisation 7 sur la lunette 6 et dans la goulotte entonnoir 18. La rampe 22 réalise en outre une opération de séchage de la lunette 6 et lorsque cela est terminé, la cuvette revient en position d'utilisation.The operation of the various devices which have just been described has been shown diagrammatically in the two series of FIGS. 4 and 5 on the one hand and 6 and 7 on the other hand for reasons of clarity. When the bowl 11 is in the use position, the valve 21 closes the communication between the chute 18 and the pipe 19, the flap 24 is in the closed position (fig. 6) and the cleaning device is in the technical area 9 (fig. 6). When the bowl pivots to come into the cleaning position, the flap 24 slides upwards, the valve 21 opens and the cleaning device 26 enters the use section 7 of the bowl 11. The ramps 22 and 31 are put into action as well as the cleaning device 26; a cleaning effect is therefore obtained in the use section 7 on the bezel 6 and in the funnel chute 18. The ramp 22 furthermore performs a drying operation of the bezel 6 and when this is finished, the bowl returns to the position of use.

L'utilisateur qui peut pénétrer alors dans l'enceinte du module sanitaire trouve une lunette parfaitement propre et sèche et une section d'utilisation, qui est la seule visible pour lui,propre.The user who can then enter the enclosure of the sanitary module finds a perfectly clean and dry bezel and a section of use, which is the only visible for him, clean.

On va décrire maintenant en détail les mécanismes d'entraînement des différents éléments mobiles qui viennent d'être décrits en se référant aux figures 4 à 8. Conformément à l'invention, tous les éléments mobiles du module sanitaire sont entraînés à partir d'un moteur unique, par exemple un moteur électrique, qui agit sur une chaîne cinématique qui comprend des dispositifs d'entraînement des différents éléments mobiles. Pour éviter que le mouvement de chacun des éléments mobiles ne constitue un danger pour un utilisateur qui se trouverait dans la zone d'utilisation lors de la phase de nettoyage, on prévoit un limiteur de couple qui est disposé en amont de la chaîne cinématique précitée de telle manière que lorsqu'il se produit un effort anormalement élevé pour l'un des mouvements prévus dans le cycle de nettoyage, la chaîne cinématique est stoppée. En réglant le seuil du limiteur de couple on peut obtenir qu'aucun effort dangereux ne puisse être exercé par un des éléments mobiles du module sur un usager se trouvant dans la zone d'utilisation.We will now describe in detail the drive mechanisms of the various mobile elements which have just been described with reference to FIGS. 4 to 8. According to the invention, all the mobile elements of the sanitary module are driven from a single motor, for example an electric motor, which acts on a kinematic chain which comprises devices for driving the various mobile elements. To prevent the movement of each of the mobile elements from constituting a danger for a user who would be in the area of use during the cleaning phase, a torque limiter is provided which is arranged upstream of the aforementioned kinematic chain of such that when an abnormally high force occurs for one of the movements provided for in the cleaning cycle, the kinematic chain is stopped. By adjusting the threshold of the torque limiter it is possible to obtain that no dangerous force can be exerted by one of the mobile elements of the module on a user in the area of use.

Avantageusement on peut prévoir en outre des dispositifs de sécurité détectant des mouvements anormaux du volet 24 et commandant l'arrêt du moteur d'entraînement; on peut par exemple prévoir un micro-interrupteur disposé derrière le volet 24 et détectant un mouvement de poussée sur ce dernier et étalement un détecteur analogue disposé sur le trajet de descente du volet 24 et détectant l'introduction d'un objet dans l'ouverture 23 lors du cycle de nettoyage.Advantageously, it is also possible to provide safety devices detecting abnormal movements of the flap 24 and controlling the stopping of the drive motor; one can for example provide a microswitch placed behind the shutter 24 and detecting a pushing movement on the latter and spreading a similar detector arranged on the descent path of the shutter 24 and detecting the introduction of an object into the opening 23 during the cleaning cycle.

De manière avantageuse, le moteur entraîne directement la cuvette 11 en rotation et tous les autres mouvements sont obtenus par l'intermédiaire de la cuvette 11; dans ce cas le limiteur de couple est disposé directement sur l'arbre du moteur.Advantageously, the motor directly drives the bowl 11 in rotation and all the other movements are obtained by means of the bowl 11; in this case the torque limiter is placed directly on the motor shaft.

Si l'on se réfère aux figures 4 et 5, on peut voir en 41 une poulie fixe qui est entraînée directement par le moteur avec interposition du limiteur de couple; cette poulie entraîne par l'intermédiaire d'une courroie 42 une autre poulie 43 qui est solidaire de la cuvette 11 et montée sur l'axe de rotation 14 de cette dernière. Comme on peut le voir sur la figure 5, la rotation de la poulie 41 dans le sens inverse des aiguilles d'une montre entraîne le basculement de la cuvette de la position d'utilisation à la position de lavage.If one refers to FIGS. 4 and 5, one can see at 41 a fixed pulley which is driven directly by the motor with the interposition of the torque limiter; this pulley drives through a belt 42 another pulley 43 which is integral with the bowl 11 and mounted on the axis of rotation 14 of the latter. As can be seen in FIG. 5, the rotation of the pulley 41 anticlockwise causes the bowl to tilt from the use position to the washing position.

Sur les figures 4 et 5 est représenté le dispositif d'actionnement du clapet 21. Ce dernier est mobile en translation horizontalement et il est actionné par un système de deux bielles 44 et 45 qui sont articulées autour d'un axe fixe 46. L'extrémité libre de la bielle 44 est articulée sur le clapet 21 et l'extrémité libre de la bielle 45 porte un galet fou 47. Par ailleurs, la face arrière de la cuvette 11 comporte une partie cylindrique 48 qui est axée sur l'axe de rotation 14 de la cuvette et qui sert de chemin de roulement pour le galet fou 47. Un logement 49 est aménagé dans la partie cylindrique 48 de manière à recevoir le galet 47 lorsque la cuvette 11 se trouve en position d'utilisation. L'ensemble de ce dispositif d'entraînement est soumis à une force de rappel qui tend à faire tourner la bielle 45 dans le sens inverse des aiguilles d'une montre, c'est-à-dire de manière à ramener le clapet 21 en position de fermeture. Lors de la rotation de la cuvette 11 et, en particulier, de sa partie cylindrique 48, le galet 47 est tout d'abord entraîné par le logement 49 dont il se dégage pour venir rouler sur la partie cylindrique 48 ce qui permet d'obtenir l'ouverture complète du clapet. Lors du mouvement de retour de la cuvette 11 vers sa position d'utilisation, le galet roule d'abord sur la surface 48 puis il pénètre dans le logement 49 sous l'effet du dispositif de rappel pour revenir dans la position représentée à la figure 4.FIGS. 4 and 5 show the device for actuating the valve 21. The latter is movable in translation horizontally and it is actuated by a system of two connecting rods 44 and 45 which are articulated around a fixed axis 46. The free end of the connecting rod 44 is articulated on the valve 21 and the free end of the connecting rod 45 carries an idler roller 47. Furthermore, the rear face of the bowl 11 has a cylindrical part 48 which is centered on the axis of rotation 14 of the bowl and which serves as a raceway for the idler roller 47. A housing 49 is arranged in the cylindrical part 48 so as to receive the roller 47 when the bowl 11 is in the position of use. The whole of this drive device is subjected to a restoring force which tends to rotate the connecting rod 45 anticlockwise, that is to say so as to bring the valve 21 back. closed position. During the rotation of the bowl 11 and, in particular, of its cylindrical part 48, the roller 47 is firstly driven by the housing 49 from which it emerges to come and roll on the cylindrical part 48 which makes it possible to obtain the complete opening of the valve. When the bowl 11 returns to its position of use, the roller first rolls on the surface 48 then it enters the housing 49 under the effect of the return device to return to the position shown in the figure 4.

Comme expliqué plus haut, les matières contenues dans la cuvette 11 se déversent dans la goulotte 18 en passant par dessus la partie arrière de la cuvette 11, c'est-à-dire la partie cylindrique 48. Il peut en résulter que celle-ci soit souillée et on peut prévoir une rampe de lavage 51 qui sera mise en oeuvre. lors du mouvement de retour de la cuvette 11.As explained above, the materials contained in the bowl 11 flow into the chute 18 by passing over the rear part of the bowl 11, that is to say the cylindrical part 48. It may result therefrom either soiled and a washing ramp 51 can be provided which will be used. during the return movement of the bowl 11.

Sur les figures 6 et 7 on a représenté les dispositifs d'entraînement du volet 24 et du dispositif de nettoyage 26.FIGS. 6 and 7 show the drive devices for the shutter 24 and the cleaning device 26.

Le volet 24 est entraîné par un ergot 52 qui vient s'accrocher dans le volet 24 et qui est porté par une courroie 53 qui s'enroule autour d'une poulie supérieure 54 et de deux poulies inférieures 55 et 56; Cette courroie 53 est fixée en 57 sur l'arête supérieure de la paroi cylindrique 48. La poulie 55 est une poulie de renvoi qui est disposée de telle manière que la partie inférieure de la courroie 53 vienne se plaquer sur la partie cylindrique 48.The flap 24 is driven by a lug 52 which hooks into the flap 24 and which is carried by a belt 53 which is wound around an upper pulley 54 and two lower pulleys 55 and 56; This belt 53 is fixed at 57 to the upper edge of the cylindrical wall 48. The pulley 55 is a return pulley which is arranged in such a way that the lower part of the belt 53 comes to rest on the cylindrical part 48.

Comme on peut le voir sur la figure, le volet 24 comporte deux parois, une paroi extérieure 58 et une paroi intérieure 59 qui descend moins bas que la paroi extérieure 58. Lorsque la cuvette est en position d'utilisation comme représenté ci-dessus, l'ergot d'entraînement 52 est disposé à une certaine distance de la paroi intérieure 59 dans laquelle il vient s'accrocher de manière à réaliser un retard à l'ouverture du mouvement de translation verticale du volet. Lorsque la cuvette 11 pivote vers sa position de nettoyage le volet vient dans la position d'ouverture représenté sur la figure 7.As can be seen in the figure, the flap 24 has two walls, an outer wall 58 and an inner wall 59 which descends lower than the outer wall 58. When the bowl is in the position of use as shown above, the drive lug 52 is disposed at a certain distance from the inner wall 59 in which it comes to hang so as to delay the opening of the vertical translation movement of the flap. When the bowl 11 pivots towards its cleaning position, the flap comes into the open position shown in FIG. 7.

Le mouvement de déplacement du dispositif de nettoyage 26 est également commandé par l'intermédiaire de la cuvette 11 qui comporte à cet effet, comme on peut voir en particulier sur les figures 2 et 3 une rainure de guidage 61 qui est aménagée dans une paroi latérale de la partie arrière de la cuvette; cette rainure sert au guidage d'un galet 62 qui est montée fou sur un axe 63 qui est fixé à l'extrémité d'un bras 64 dont l'autre extrémité est solidaire d'une poulie 65. Cette poulie 65 est montée à rotation autour d'une axe fixe 66; cette poulie 65 entraîne une courroie 67 qui s'engrène par ailleurs sur une poulie 68 qui tourne autour d'un axe fixe 69 et qui est solidaire d'un bras 71. Le bras 71 porte à son autre extrémité un axe 72 sur lequel est monté à rotation libre une poulie 73 qui est solidaire du bras support 29 supportant le dispositif de nettoyage 26. La poulie 73 entraîne une courroie 74 qui s' engrène également sur une poulie fixe 75 qui est solidaire de l'axe 69. L'ensemble de ces différents éléments est représenté schématiquement sur la figure 8.The movement of movement of the cleaning device 26 is also controlled by means of the bowl 11 which for this purpose comprises, as can be seen in particular in FIGS. 2 and 3, a guide groove 61 which is arranged in a side wall from the back of the bowl; this groove is used to guide a roller 62 which is mounted idly on an axis 63 which is fixed to the end of an arm 64, the other end of which is integral with a pulley 65. This pulley 65 is mounted for rotation around a fixed axis 66; this pulley 65 drives a belt 67 which also meshes with a pulley 68 which rotates around a fixed axis 69 and which is secured to an arm 71. The arm 71 carries at its other end an axis 72 on which is mounted with free rotation a pulley 73 which is integral with the support arm 29 supporting the cleaning device 26. The pulley 73 drives a belt 74 which also engages on a fixed pulley 75 which is integral with the axis 69. The assembly of these different elements is shown diagrammatically in FIG. 8.

Le fonctionnement de ce dispositif cinématique est le suivant. Comme on peut le voir en particulier sur les figures 6 et 7, la rainure de guidage 61 comporte une partie circulaire 76 qui est centrée sur l'axe 14 de rotation de la cuvette et qui se prolonge par une partie rectiligne 77 qui est sensiblement horizontale lorsque la cuvette est en position d'utilisation. Lors du mouvement de rotation de la cuvette, tant que le galet 62 circule dans la partie circulaire 76 de la rainure 61, il ne se produit aucun mouvement; par contre, lorsque le galet 62 décrit la partie rectiligne 77, le bras 64 est entraîné en rotation dans le sens inverse des aiguilles d'une montre, ce qui entraîne la rotation de la poulie 65 et par suite la rotation dans le même sens de la poulie 68 si bien que le bras 71 tourne dans le sens inverse des aiguilles d'une montre pour venir dans la position représentée sur la figure 7.The operation of this kinematic device is as follows. As can be seen in particular in FIGS. 6 and 7, the guide groove 61 has a circular part 76 which is centered on the axis 14 of rotation of the bowl and which is extended by a rectilinear part 77 which is substantially horizontal when the bowl is in the use position. During the rotational movement of the bowl, as long as the roller 62 circulates in the circular part 76 of the groove 61, there is no movement; on the other hand, when the roller 62 describes the rectilinear part 77, the arm 64 is driven in rotation in an anticlockwise direction, which causes the pulley 65 to rotate and consequently the rotation in the same direction of the pulley 68 so that the arm 71 rotates anti-clockwise to come into the position shown in FIG. 7.

Le dépliement du bras 29 suportant les pales de nettoyage 27 s'effectue de la manière suivante. Comme indiqué ci-dessus, lors du mouvement de rotation de la cuvette 11 vers sa position de nettoyage, le bras 71 tourne dans le sens inverse des aiguilles d'une montre autour de l'axe 69 ; il entraîne dans ce mouvement la poulie 74 qui, du fait que la poulie 75 est fixe, est entraîné en rotation dans le sens des aiguilles d'une montre ce qui entraîne la rotation du bras 29 dans le sens des aiguilles d'une montre autour de l'axe 72 et ce bras 29 se déplie par rapport au bras 71. Comme on l'a vu plus haut, ce mouvement est retardé par la partie circulaire inactive 76 de la rainure de guidage 61.The unfolding of the arm 29 supporting the cleaning blades 27 is carried out as follows. As indicated above, during the rotational movement of the bowl 11 towards its cleaning position, the arm 71 rotates anti-clockwise around the axis 69; in this movement it drives the pulley 74 which, due to the fact that the pulley 75 is fixed, is rotated clockwise which causes the arm 29 to rotate clockwise around of the axis 72 and this arm 29 unfolds relative to the arm 71. As we saw above, this movement is delayed by the inactive circular part 76 of the guide groove 61.

Avantageusement, on peut munir la courroie 53 d'une butée 78 disposée juste au-dessus du volet 24 lorsque la cuvette se trouve en position d'utilisation; cette butée sert de sécurité et empêche tout actionnement manuel lorsque ce dernier est en position de fermeture.Advantageously, the belt 53 can be provided with a stop 78 positioned just above the flap 24 when the bowl is in the use position; this stop serves as security and prevents any manual actuation when the latter is in the closed position.

Selon l'invention, on peut prévoir qu'un cycle de lavage puisse être commandé par un utilisateur se trouvant dans le module sanitaire; ce cycle peut être un cycle normal de nettoyage ou un cycle plus court. Cela est possible puisque, comme indiqué plus haut, le module sanitaire est à sécurité totale du fait de la présence du limiteur de couple. Avantageusement, on prévoit par exemple dans la cloison 12 au-dessus de la cuvette 11 un dispositif d'affichage 79 qui fournit des explications sur le fonctionnement et le déroulement du cycle de nettoyage. Ce dispositif d'affichage peut comporter, par exemple, des indications colorées symbolisant les différentes phases (nettoyage, désinfection séchage... etc.).According to the invention, provision can be made for a washing cycle to be able to be controlled by a user in the sanitary module; this cycle can be a normal cleaning cycle or a shorter cycle. This is possible since, as indicated above, the sanitary module is totally safe due to the presence of the torque limiter. Advantageously, provision is made, for example, in the partition 12 above the bowl 11 for a display device 79 which provides explanations on the operation and progress of the cleaning cycle. This display device may include, for example, colored indications symbolizing the different phases (cleaning, disinfection, drying, etc.).

La zone technique étant de faibles dimensions, il n'est pas possible de prévoir d'y accéder par l'extérieur de l'enceinte du module sanitaire; par conséquent on prévoit un capot aménagé dans la cloison 12 et dont l'ouverture permet l'entretien des différents éléments mécaniques du module.The technical area is small, it is not possible to plan to access it from outside the enclosure of the sanitary module; therefore a cover is provided in the partition 12 and whose opening allows the maintenance of the various mechanical elements of the module.

Selon une variante de réalisation représentée sur les figures 9 et 10, on prévoit également un capot vertical 91 articulé qui peut s'ouvrir pour donner accès à la zone technique 9 et l'accès à cette zone technique qui est de dimension réduite est encore facilité par le fait que la cuvette 92 constitue également un capot recouvrant l'essentiel du dispositif d'entraînement et cette cuvette 92 peut être enlevée comme représentée sur la figure 10 pour accéder aux dispositifs d'entraînement. On peut également prévoir que les parties 93 et 94 de la paroi de séparation qui sont disposées de part et d'autre de la cuvette 92 soient montées de manière à pouvoir s'ouvrir comme représenté sur la figure 10 de telle manière que l'on puisse accéder à l'ensemble de la zone technique 9.According to an alternative embodiment shown in Figures 9 and 10, there is also provided a hinged vertical cover 91 which can open to give access to the technical area 9 and access to this technical area which is of reduced size is further facilitated by the fact that the bowl 92 also constitutes a cover covering most of the drive device and this bowl 92 can be removed as shown in FIG. 10 to access the drive devices. It is also possible to provide that the parts 93 and 94 of the partition wall which are arranged on either side of the bowl 92 are mounted so as to be able open as shown in Figure 10 so that you can access the entire technical area 9.

Pour simplifier les opérations d'entretien, il est avantageux de prévoir un système de graissage centralisé des différents éléments mécaniques alimentés par une cartouche contenant un produit de graissage et dont le remplacement est effectué de manière régulière.To simplify maintenance operations, it is advantageous to provide a centralized lubrication system for the various mechanical elements supplied by a cartridge containing a lubrication product and the replacement of which is carried out regularly.

Pour éviter une éventuelle projection de liquide dans la zone d'utilisation pendant le cycle de nettoyage, on peut prévoir une bavette de protection souple 81 qui est disposée sur le pourtour de l'ouverture aménagée dans la cloison 12 qui est fermée en position d'utilisation par le volet 24 et dont la forme correspond au profil de la lunette.To avoid any projection of liquid into the zone of use during the cleaning cycle, a flexible protective flap 81 can be provided which is disposed around the periphery of the opening in the partition 12 which is closed in the position of use by the flap 24 and whose shape corresponds to the profile of the telescope.

Sur les figures 2 et 3, on a présenté deux variantes de réalisation de la partie arrière de la cuvette 11; dans le mode de réalisation de la figure 2, on prévoit de part et d'autre de la partie cylindrique 48 deux logements 82 et 83 qui sont destinés à recevoir le dispositif d'entraînement de la cuvette en rotation et qui sont fermés par deux parois latérales amovibles 84 et 85. Dans ce mode de réalisation, l'ensemble du mécanisme d'entraînement de la cuvette est donc masqué par les parois 84 et 85. Dans le mode de réalisation de la figure 3, le dispositif mécanique d'entraînement de la cuvette est disposé à l'extérieur de celle-ci.In Figures 2 and 3, there are shown two alternative embodiments of the rear part of the bowl 11; in the embodiment of Figure 2, there are provided on either side of the cylindrical part 48 two housings 82 and 83 which are intended to receive the device for driving the bowl in rotation and which are closed by two walls removable side panels 84 and 85. In this embodiment, the entire mechanism for driving the bowl is therefore hidden by the walls 84 and 85. In the embodiment of FIG. 3, the mechanical device for driving the bowl is arranged outside of it.

On voit que l'invention permet de réaliser un module sanitaire dans lequel les opérations de nettoyage sont réalisées en toute sécurité; on particulier on réalise un nettoyage et un séchage parfait de la lunette de telle sorte que l'utilisateur n'aie de réticence à l'utiliser de manière normale. Par ailleurs, la possibilité de déclencher le cycle de lavage par l'utilisateur et les explications fournies par le dispositif d'affichage permettent de vaincre toutes les réticences qui pourraient exister.It can be seen that the invention makes it possible to produce a sanitary module in which the cleaning operations are carried out in complete safety; in particular, a perfect cleaning and drying of the telescope is carried out so that the user has no reluctance to use it in a normal manner. Furthermore, the possibility of triggering the washing cycle by the user and the explanations provided by the display device make it possible to overcome any reluctance that might exist.

Le module sanitaire selon l'invention est de dimensions réduites et il est plus particulièrement destiné à des endroits publics ou semi-publics protégés tels que des halls de gares, des stations-services, etc. Les dimensions de ce module sont suffisamment réduites pour qu'on puisse envisager son intégration dans un logement privé.The sanitary module according to the invention is of reduced dimensions and it is more particularly intended for protected public or semi-public places such as station halls, petrol stations, etc. The dimensions of this module are small enough that we can consider its integration into private accommodation.
