Description

L'invention se rapporte au domaine technique des installations sanitaires à nettoyage automatique et, plus particulièrement, aux installations d'aisance ou toilettes à usage public ou collectif.The invention relates to the technical field of sanitary installations in automatic cleaning and, more particularly, in toilets or toilets for public or collective use.

Dans le domaine ci-dessus, on connaít des installations d'aisance comprenant un local sanitaire accessible aux utilisateurs ou au public et à l'intérieur duquel est disposée une cuvette de toilettes, dite "à l'anglaise". Le local sanitaire est contigu à un local technique d'accès contrôlé refermant différents moyens permettant d'assurer un nettoyage automatique de la cuvette et du local sanitaire après le passage d'un utilisateur.In the area above, there are known toilet facilities including a sanitary room accessible to users or to the public and inside which is arranged a toilet bowl, called "English". The sanitary room is adjoining a technical room with controlled access enclosing various means allowing ensure automatic cleaning of the bowl and the sanitary room after passage of a user.

L'art antérieur a proposé différents dispositifs de nettoyage automatique qu'il est notamment possible de distinguer selon que la cuvette est fixe ou mobile.The prior art has proposed various automatic cleaning devices which it It is in particular possible to distinguish according to whether the bowl is fixed or mobile.

A titre d'exemple de dispositif de la première catégorie, il convient de signaler la demande de brevet EP 0 059 134, selon laquelle la cuvette fixe est disposée à l'intérieur d'un local sanitaire et adossée à une cloison séparant le local sanitaire d'un local technique. Cette cloison présente, à proximité du siège de la cuvette, un guichet obturé par un panneau mobile indépendant, asservi en ouverture et en fermeture. De plus, l'installation comprend, à l'intérieur du local technique, un système de chasse d'eau et, en regard dudit guichet, un dispositif extensible de nettoyage automatique du siège et de l'avant de la cuvette. Ce dispositif est formé par une paire de vérins hydrauliques double effet, orientés selon une direction horizontale et à l'extrémité desquels est fixée une seconde paire de vérins dirigés verticalement vers le sol. La seconde paire de vérins porte, à son extrémité, une brosse rotative. Enfin, le fonctionnement de cette installation est assuré de manière automatique par un bloc de commande.As an example of a device of the first category, it is worth mentioning patent application EP 0 059 134, according to which the fixed bowl is placed inside a sanitary room and leaned against a partition separating the sanitary room. a technical room. This partition has, near the seat of the bowl, a window closed by an independent movable panel, controlled in opening and closing. In addition, the installation includes, inside the technical room, a flushing system and, opposite said window, an extendable device for automatic cleaning of the seat and the front of the bowl. This device is formed by a pair of double-acting hydraulic cylinders, oriented in a horizontal direction and at the end of which is fixed a second pair of cylinders directed vertically towards the ground. The second pair of cylinders carries, at its end, a rotating brush. Finally, the operation of this installation is ensured automatically by a control block.

Après passage d'un utilisateur et déclenchement de la chasse d'eau, le bloc de commande assure un cycle de nettoyage de la cuvette. Pour ce faire, le panneau est relevé afin de libérer le passage pour le dispositif de nettoyage qui est amené en extension pour mettre la brosse rotative en contact successivement du siège et de l'avant de la cuvette. Après ce cycle de nettoyage, le dispositif est ramené dans le local technique et le panneau refermé. After passage of a user and triggering of the flush, the block of control ensures a bowl cleaning cycle. To do this, the panel is raised in order to free the passage for the cleaning device which is brought into extension for bring the rotary brush in contact successively with the seat and the front of the bowl. After this cleaning cycle, the device is brought back to the technical room and the panel closed.

Une telle installation permet, effectivement, d'assurer un nettoyage automatique de la cuvette, mais présente toutefois certains inconvénients. En effet, le nettoyage de la cuvette dans le local sanitaire contribue à salir ce dernier par la projection de souillures qui sont ensuite difficiles à ôter et préjudiciables à l'aspect de propreté que devrait présenter l'installation d'aisance. Un tel inconvénient se retrouve généralement pour toutes les installations à cuvette fixe dont le nettoyage est assuré dans le local sanitaire.Such an installation effectively ensures cleaning automatic bowl, but has certain drawbacks. Indeed, the cleaning the bowl in the sanitary room contributes to dirty it by the projection of stains which are then difficult to remove and detrimental to the aspect of cleanliness that should present the commode. Such a drawback is generally found for all fixed bowl installations which are cleaned in the sanitary room.

Afin de remédier aux inconvénients inhérents aux installations comportant une cuvette fixe et un dispositif mobile de nettoyage, l'art antérieur a proposé des installations d'aisance à nettoyage automatique dans lesquelles la cuvette est mobile. L'invention vise, plus particulièrement, cette seconde catégorie d'installations.In order to overcome the drawbacks inherent in installations with a fixed bowl and a mobile cleaning device, the prior art has proposed installations with automatic cleaning in which the bowl is movable. The invention aims, more particularly, this second category of installations.

On connaít, par exemple, des installations d'aisance, comportant des cuvettes mobiles et un dispositif fixe de nettoyage automatique. Une telle installation comprend une cloison séparant les locaux technique et sanitaire et comportant, à sa base, un panneau mobile autour d'un axe vertical. De part et d'autre de ce panneau, sont suspendues deux cuvettes identiques raccordées à une canalisation d'évacuation unique formant un des pivots du panneau. Après passage d'un utilisateur, le panneau pivote d'un demi-tour intervertissant les positions de la cuvette utilisée et de celle précédemment nettoyéé, située jusqu'alors dans le local technique. La cuvette utilisée est ainsi placée à l'intérieur du local technique sous un dispositif fixe qui en assure un nettoyage automatique.We know, for example, toilet facilities, including bowls mobile and a fixed automatic cleaning device. Such an installation includes a partition separating the technical and sanitary premises and comprising, at its base, a panel movable around a vertical axis. On either side of this panel are suspended two identical bowls connected to a single drainage pipe forming one of the panel pivots. After a user has passed, the panel rotates by half a turn reversing the positions of the bowl used and that previously cleaned, located until then in the technical room. The bowl used is thus placed inside the room technique under a fixed device which ensures automatic cleaning.

Ce dispositif donne entière satisfaction pour le nettoyage alterné des cuvettes, mais présente des inconvénients majeurs dus à sa structure. Tout d'abord, une telle conception double le nombre des cuvettes, impose un mécanisme d'asservissement du panneau et fait donc naítre un prix de fabrication élevé. Ensuite, l'existence d'un joint pivotant à la base du panneau constitue une source de dysfonctionnement, en raison des contraintes résultant du porte-à-faux engendré par l'utilisation de la cuvette située dans le local sanitaire. Enfin, la rotation des cuvettes nécessite un certain espace libre qui est à l'origine de l'encombrement important d'une telle installation.This device is entirely satisfactory for alternating cleaning of the bowls, but has major drawbacks due to its structure. First of all, such design doubles the number of bowls, imposes a mechanism to control the panel and therefore creates a high manufacturing price. Then the existence of a joint pivoting at the base of the panel is a source of malfunction due to stresses resulting from the overhang generated by the use of the bowl located in the sanitary room. Finally, the rotation of the bowls requires a certain free space which is the origin of the large size of such an installation.

Afin de remédier au problème d'encombrement, l'art antérieur connaít également des installations sanitaires à nettoyage automatique qui comportent une seule cuvette mobile entre le local sanitaire et le local technique dans lequel la cuvette subit un cycle de nettoyage automatique. Ainsi, à titre d'exemple de ce type d'installation, il convient de signaler la demande de brevet FR 2 415 173, selon laquelle la cuvette est montée sur une cloison séparant le local sanitaire du local technique et bascule à l'intérieur de ce dernier pour y subir un cycle de vidange et de nettoyage après passage d'un utilisateur. Un tel dispositif permet certainement un nettoyage efficace de la cuvette, mais présente une cinématique et des automatismes complexes qui impliquent un coût de fabrication élevé et réduisent la fiabilité de l'installation entraínant ainsi un coût d'exploitation particulièrement lourd. De plus, la cinématique et le mécanisme de déplacement de la cuvette présentent le risque d'entraíner un utilisateur de faible poids dans le dispositif de nettoyage.In order to remedy the problem of space, the prior art also knows sanitary installations with automatic cleaning which comprise a single movable bowl between the sanitary room and the technical room in which the bowl undergoes an automatic cleaning cycle. Thus, by way of example of this type of installation, it is worth mentioning the patent application FR 2 415 173 , according to which the bowl is mounted on a partition separating the sanitary room from the technical room and switches inside the latter to undergo a draining and cleaning cycle after passage of a user. Such a device certainly allows effective cleaning of the bowl, but has complex kinematics and automatisms which involve a high manufacturing cost and reduce the reliability of the installation thus resulting in a particularly heavy operating cost. In addition, the kinematics and the movement mechanism of the bowl present the risk of causing a user of low weight in the cleaning device.

Un but de l'invention est de remédier à l'ensemble des inconvénients ci-dessus en proposant un procédé de nettoyage d'une installation d'aisance à cuvette mobile qui présente une cinématique simple, gage de fiabilité, et qui offre des garanties d'hygiène suffisantes.An object of the invention is to remedy all of the above drawbacks by proposing a method of cleaning a mobile toilet installation which presents a simple kinematics, pledge of reliability, and which offers guarantees of hygiene sufficient.

Pour atteindre ces objectifs, le procédé de nettoyage d'une installation d'aisance comprenant une cuvette d'aisance pourvue d'un siège et mobile entre un local sanitaire et un local technique séparé du local sanitaire par une cloison, fait intervenir des opérations d'aspersion et de séchage du siège au moins.To achieve these objectives, the process of cleaning an installation commode comprising a commode fitted with a seat and movable between a room sanitary and a technical room separated from the sanitary room by a partition, involves at least seat spraying and drying operations.

Selon l'invention, ce procédé consiste à :

  • assurer une course de rentrée, en translation, de la cuvette entre une position d'extension dans le local sanitaire et une position de rétraction dans le local technique sous des moyens de projection de liquide sous pression et de séchage,
  • alimenter les moyens de projection pour asperger au moins toute la surface du siège,
  • alimenter les moyens de séchage pour sécher au moins toute la surface du siège,
  • assurer une course de sortie de la cuvette en sens inverse.
According to the invention, this method consists in:
  • ensuring a return travel, in translation, of the bowl between an extension position in the sanitary room and a retraction position in the technical room under means of spraying liquid under pressure and drying,
  • supply the projection means to spray at least the entire surface of the seat,
  • supply the drying means to dry at least the entire surface of the seat,
  • ensure an outlet stroke in the opposite direction.

Selon une autre caractéristique de l'invention, le procédé consiste à asperger le siège et les parois internes de la cuvette au moyen d'au moins un jet rotatif. De manière préférée, chacune des régions de la cuvette, constituées respectivement par le fond, les flancs de la paroi interne et le siège, est aspergée au moyen d'au moins un jet rotatif par région. According to another characteristic of the invention, the method consists in spraying the seat and internal walls of the bowl by means of at least one rotating jet. So preferred, each of the regions of the bowl, constituted respectively by the bottom, the sides of the inner wall and the seat, is sprayed by means of at least one rotary jet by region.

Un autre but de l'invention est d'obvier aux inconvénients des installations susmentionnées en proposant une installation d'aisance qui présente, d'une part, un coût de fabrication réduit et, d'autre part, une garantie d'hygiène et une fiabilité de fonctionnement assurant un faible coût d'exploitation.Another object of the invention is to obviate the drawbacks of the installations above by proposing a toilet facility which presents, on the one hand, a cost of reduced manufacturing and, on the other hand, a guarantee of hygiene and operational reliability ensuring a low operating cost.

Pour atteindre ces objectifs, l'installation d'aisance comprend :

  • une cuvette d'aisance pourvue d'un siège mobile entre un local sanitaire accessible au public et un local technique séparé du local sanitaire par une cloison,
  • un dispositif de nettoyage automatique, du siège au moins de la cuvette, disposé dans le local technique,
  • des moyens moteurs pour déplacer la cuvette,
  • et une unité de commande pour piloter au moins le fonctionnement du dispositif de nettoyage et des moyens moteurs.
To achieve these objectives, the toilet facility includes:
  • a toilet bowl provided with a movable seat between a sanitary room accessible to the public and a technical room separated from the sanitary room by a partition,
  • an automatic cleaning device, of the seat at least of the bowl, arranged in the technical room,

    • L'installation d'aisance 1 illustrée à la fig. 1 est conçue pour former un module sanitaire autonome destiné à être implanté sur la voie publique. Bien entendu, un tel module ne constitue qu'une forme préférée de réalisation d'une installation conforme à l'invention qui pourrait aussi être, par exemple, mise en place à l'intérieur d'un bâtiment pour un usage par les membres d'une collectivité.The installation of ease 1 illustrated in FIG. 1 is designed to form an autonomous sanitary module intended to be installed on the public highway. Of course, such a module is only a preferred embodiment of an installation according to the invention which could also, for example, be placed inside a building for use by the members of 'a community.

    L'installation 1 comprend un local sanitaire 2 accessible aux utilisateurs par une porte 3 et séparé d'un local technique 4 par une cloison 5. Conformément à sa destination, l'installation comprend également une cuvette de toilettes 6, dite "à l'anglaise", comportant un siège 7. La cuvette 6 est mobile entre une position d'extension A à l'intérieur du local sanitaire, comme illustré à la fig. 1, et une position de rétraction B à l'intérieur du local technique 4, tel que le montre la fig. 2. Selon l'invention, la cuvette 6 est mobile en translation entre les positions A et B au travers d'un guichet 8 ménagé en partie basse de la cloison 5. A cette fin, la cuvette 6 est solidaire d'un équipage mobile 10 situé à l'arrière de la cuvette 6 et faisant partie intégrante de cette dernière. Bien entendu, la cuvette 6 pourrait également être rapportée et fixée en console sur un tel équipage mobile 10. De manière préférée, l'équipage coulissant 10 est supporté et guidé en translation par au moins deux glissières 11 disposées, de préférence mais non exclusivement, de part et d'autre dudit équipage 10, comme cela ressort de la fig. 3. Les glissières 11 sont, par exemple, chacune formée par un guide 12 solidaire d'un côté de l'équipage 10 et coulissant sur un tube 13 fixé sur une structure porteuse 14 interne au local technique 4. L'équipage mobile 10 est alors actionné par des moyens moteurs constitués d'un moto-réducteur 15 qui est adapté sur l'équipage mobile 10 et dont le pignon 16 s'engrène sur une crémaillère fixe 17 solidaire de la structure porteuse 14. Le moto-réducteur 15 est raccordé par une ligne 18 à une unité ou bloc de commande 20 qui en pilote le fonctionnement. Ce mode de montage de la cuvette permet avantageusement de n'occuper aucune place au sol, dans le local sanitaire, lorsque la cuvette est en position de rétraction.The installation 1 includes a sanitary room 2 accessible to users by a door 3 and separated from a technical room 4 by a partition 5 . In accordance with its intended purpose, the installation also includes a toilet bowl 6 , called "English-style", comprising a seat 7 . The bowl 6 is movable between an extension position A inside the sanitary room, as illustrated in FIG. 1 , and a retraction position B inside the technical room 4 , as shown in FIG. 2 . According to the invention, the bowl 6 is movable in translation between positions A and B through a window 8 formed in the lower part of the partition 5 . To this end, the bowl 6 is integral with a movable assembly 10 located at the rear of the bowl 6 and forming an integral part of the latter. Of course, the bowl 6 could also be added and fixed in a console on such a mobile assembly 10 . Preferably, the sliding element 10 is supported and guided in translation by at least two slides 11 arranged, preferably but not exclusively, on either side of said element 10 , as can be seen in FIG. 3 . The slides 11 are, for example, each formed by a guide 12 secured to one side of the crew 10 and sliding on a tube 13 fixed to a support structure 14 internal to the technical room 4 . The moving element 10 is then actuated by motor means consisting of a geared motor 15 which is adapted to the moving element 10 and whose pinion 16 meshes with a fixed rack 17 integral with the carrying structure 14 . The gear motor 15 is connected by a line 18 to a control unit or block 20 which controls its operation. This method of mounting the bowl advantageously makes it possible to occupy no place on the ground, in the sanitary room, when the bowl is in the retraction position.

    La cuvette 6 comporte un siphon 21 raccordé par une conduite flexible 22 à une canalisation 23 d'évacuation des eaux vannes ou usées. La cuvette 6 est branchée par un tuyau souple 25 à un système de chasse d'eau 26, ou analogue, disposé dans le local technique 4. Ce système 26 est constitué d'un réservoir 27 placé en hauteur et d'une électrovanne 28 commandant le tuyau 25. L'électrovanne 28 est reliée par une ligne 29 à l'unité de commande 20 qui en assure l'asservissement. Le réservoir 27 est, par ailleurs, raccordé à un réseau de distribution d'eau 30 et pourvu d'un distributeur 31 additionnant à l'eau un produit antiseptique chloré ou analogue, en fonction du remplissage du réservoir 27.The bowl 6 comprises a siphon 21 connected by a flexible pipe 22 to a pipe 23 for evacuating valve or waste water. The bowl 6 is connected by a flexible pipe 25 to a flushing system 26 , or the like, arranged in the technical room 4 . This system 26 consists of a reservoir 27 placed high up and of a solenoid valve 28 controlling the pipe 25 . The solenoid valve 28 is connected by a line 29 to the control unit 20 which ensures its control. The reservoir 27 is, moreover, connected to a water distribution network 30 and provided with a distributor 31 adding to the water a chlorinated antiseptic product or the like, depending on the filling of the reservoir 27 .

    Pour assurer le nettoyage de la cuvette, l'installation 1 comprend également un dispositif 35, de préférence fixe et sous lequel la cuvette est destinée à venir se placer en position de rétraction B.To ensure the cleaning of the bowl, the installation 1 also comprises a device 35 , preferably fixed and under which the bowl is intended to be placed in the retraction position B.

    Le dispositif nettoyage 35 est conçu pour nettoyer au moins le siège 7 de la cuvette 6 et comporte, à cette fin, des moyens 36 de projection de liquide sous pression en direction du siège, et des moyens 37 de séchage de ce dernier.The cleaning device 35 is designed to clean at least the seat 7 of the bowl 6 and comprises, for this purpose, means 36 for spraying pressurized liquid towards the seat, and means 37 for drying the latter.

    Les moyens de projection 36 sont branchés par une canalisation 38 à une source d'alimentation 39 en liquide sous pression, tel que par exemple, un surpresseur raccordé au réservoir 27 par une canalisation 40 et connectée à l'unité de commande 20 par une ligne 41. La canalisation 38 est commandée par une électrovanne 42 connectée par une ligne 43 au bloc de commande 20. Les moyens de projection 36 sont conçus de façon à couvrir ou à atteindre l'intégralité du siège 7 lorsque la cuvette 6 est en position de rétraction B. Pour cela, les moyens de projection 36 peuvent, par exemple, être constitués par un système de gicleurs rotatifs qui, d'une part, projettent le liquide sous pression en direction du siège 7 et, d'autre part, aspergent les parois internes de la cuvette 6. Les moyens de projection 36 pourraient également être constitués par des gicleurs fixes disposés convenablement.The projection means 36 are connected by a pipe 38 to a supply source 39 of pressurized liquid, such as for example, a booster connected to the reservoir 27 by a pipe 40 and connected to the control unit 20 by a line 41 . The pipe 38 is controlled by a solenoid valve 42 connected by a line 43 to the control unit 20 . The projection means 36 are designed so as to cover or reach the whole of the seat 7 when the bowl 6 is in the retraction position B. For this, the projection means 36 may, for example, be constituted by a system of rotary nozzles which, on the one hand, project the liquid under pressure towards the seat 7 and, on the other hand, spray the internal walls of bowl 6 . The projection means 36 could also consist of fixed nozzles suitably arranged.

    Les moyens de séchage 37 sont formés, de préférence, par une tuyère raccordée à une source d'air pulsé 44, telle que par exemple un ventilateur électrique connecté par une ligne 45 au bloc de commande 20. Cet air pulsé est, de préférence, à température ambiante mais il pourrait aussi être réchauffé par des résistances équipant la source 44. Les moyens de séchage 37 pourraient aussi être réalisés sous la forme de sources radiantes de chaleur, telles que des tubes à infrarouge.The drying means 37 are preferably formed by a nozzle connected to a source of forced air 44 , such as for example an electric fan connected by a line 45 to the control unit 20 . This forced air is preferably at ambient temperature, but it could also be heated by resistors fitted to the source 44 . The drying means 37 could also be produced in the form of radiant heat sources, such as infrared tubes.

    De même que pour les moyens de projection 36, les moyens de séchage 37 sont conçus pour couvrir au moins toute la surface du siège 7, lorsque ce dernier est en position de rétraction B.As with the projection means 36 , the drying means 37 are designed to cover at least the entire surface of the seat 7 , when the latter is in the retraction position B.

    Comme le montrent les fig. 2 et 3, la tuyère 37 est, de préférence, définie par un carter 45 ouvert vers la cuvette, de manière à couvrir au moins toute la surface du siège. Ce carter 45 est pourvu d'un déflecteur central 46 disposé de manière à être au-dessus de l'ouverture délimitée par le siège 7, lorsque la cuvette 6 est en position de rétraction B. Le déflecteur 46 couvre la surface de l'ouverture délimitée par le siège 7 pour diriger le flux d'air canalisé par le carter vers ledit siège 7. De manière préférée, le système de gicleurs rotatifs, formant les moyens de projection 36, est placé sous le déflecteur 46 qui ainsi évite les projections de liquide à l'intérieur du carter 45.As shown in fig. 2 and 3 , the nozzle 37 is preferably defined by a casing 45 open towards the bowl, so as to cover at least the entire surface of the seat. This casing 45 is provided with a central deflector 46 arranged so as to be above the opening delimited by the seat 7 , when the bowl 6 is in the retraction position B. The deflector 46 covers the surface of the opening delimited by the seat 7 in order to direct the air flow channeled by the casing towards said seat 7 . Preferably, the system of rotary nozzles, forming the projection means 36 , is placed under the deflector 46 which thus prevents liquid splashes inside the casing 45 .

    L'unité de commande 20 pilote le fonctionnement séquentiel de l'installation 1, telle qu'elle vient d'être décrite, pour assurer, notamment, le nettoyage de la cuvette 6, conformément au procédé selon l'invention.The control unit 20 controls the sequential operation of the installation 1 , as just described, to ensure, in particular, the cleaning of the bowl 6 , in accordance with the method according to the invention.

    Après passage d'un utilisateur, contrôlé par des moyens connus et n'entrant pas directement dans le cadre de l'invention, et déclenchement automatique ou non de la chasse d'eau par l'intermédiaire d'une ouverture temporaire de l'électrovanne 28, l'unité 20 assure la rentrée de la cuvette 6 depuis sa position d'extension A jusqu'à sa position de rétraction B à l'intérieur du local technique sous le dispositif de nettoyage 35. Afin d'annuler le risque de blesser un utilisateur par les mouvements de la cuvette, le motoréducteur 15 et/ou l'unité de commande 20 sont équipés d'un détecteur 47 de couple mécanique qui permet de déceler un éventuel obstacle au déplacement de la cuvette pour interrompre les mouvements de celle-ci jusqu'à disparition totale de l'obstacle.After a user has passed, controlled by known means and not directly within the scope of the invention, and automatic or not triggering of the flushing by means of a temporary opening of the solenoid valve 28 , the unit 20 ensures the return of the bowl 6 from its extension position A to its retraction position B inside the technical room under the cleaning device 35 . In order to cancel the risk of injuring a user by the movements of the bowl, the gearmotor 15 and / or the control unit 20 are equipped with a mechanical torque detector 47 which makes it possible to detect a possible obstacle to the movement of the bowl to interrupt its movements until the obstacle completely disappears.

    Le bloc de commande 20 déclenche ensuite un cycle de nettoyage du siège 7. Ce cycle comporte deux phases distinctes, une première d'aspersion de liquide aseptisant et une seconde de séchage. De manière préférée, le réservoir 27 présente une capacité suffisante pour permettre plusieurs passages d'utilisateurs et plusieurs cycles de nettoyage sans nécessiter un nouveau remplissage. The control unit 20 then triggers a seat cleaning cycle 7 . This cycle comprises two distinct phases, a first of spraying of sanitizing liquid and a second of drying. Preferably, the reservoir 27 has sufficient capacity to allow several user passages and several cleaning cycles without requiring refilling.

    Lors de la première phase, l'unité 20 commande le fonctionnement du surpresseur 39 et l'ouverture de l'électrovanne 42 pour alimenter les moyens de projection 36. Des gicleurs latéraux du système rotatif assurent alors une projection de liquide sous pression en direction du siège 7 et en balaient l'intégralité par leur rotation, tandis que des gicleurs dirigés vers le bas projettent le liquide sous pression en direction des parois internes de la cuvette 6, de sorte que les éventuelles souillures y adhérant en sont décollées.During the first phase, the unit 20 controls the operation of the booster 39 and the opening of the solenoid valve 42 to supply the projection means 36 . Lateral nozzles of the rotary system then project a liquid under pressure towards the seat 7 and sweep all of them by their rotation, while nozzles directed downwards project the liquid under pressure towards the internal walls of the bowl 6 , so that any stains adhering to it are removed.

    Compte tenu du caractère aseptique du liquide et de la pression, ce balayage assure une désinfection du siège 7 et de l'intérieur de la cuvette 6, ainsi que l'élimination des souillures éventuelles par le déplacement de fronts d'eau générés par les gicleurs rotatifs.Given the aseptic nature of the liquid and the pressure, this sweeping ensures disinfection of the seat 7 and the interior of the bowl 6 , as well as the elimination of any stains by the displacement of water fronts generated by the nozzles. rotary.

    Après aspersion de la cuvette 6, l'unité 20 déclenche la marche de la source d'air pulsé 44 pour alimenter les moyens de séchage 37. Afin d'obtenir un séchage le plus efficace possible, le carter 45 et le déflecteur 46 sont conçus de manière que la section de sortie de la tuyère ait une forme en plan sensiblement analogue à celle du siège 7 et se trouve juste au-dessus de ce dernier, de sorte que le flux d'air, canalisé par la tuyère, s'y trouve préférentiellement dirigé. De manière avantageuse, le flux d'air, canalisé simultanément sur sensiblement toute la surface du siège, y évite les accumulations d'eau et en assure un séchage efficace.After spraying the bowl 6 , the unit 20 starts the operation of the source of forced air 44 to supply the drying means 37 . In order to obtain the most efficient drying possible, the casing 45 and the deflector 46 are designed so that the outlet section of the nozzle has a plan shape substantially similar to that of the seat 7 and is located just above the latter, so that the air flow, channeled by the nozzle, is preferably directed there. Advantageously, the air flow, channeled simultaneously over substantially the entire surface of the seat, prevents water from accumulating there and ensures effective drying.

    L'unité 20 interrompt ensuite le fonctionnement de la source d'air pulsé 44 et commande la sortie de la cuvette 6 en position d'extension B pour placer l'installation 1 dans une situation d'accueil d'un nouvel utilisateur.The unit 20 then interrupts the operation of the source of forced air 44 and controls the outlet of the bowl 6 in the extended position B to place the installation 1 in a position for welcoming a new user.

    Le procédé selon l'invention permet d'assurer un nettoyage complet et efficace de la cuvette sans salissement du local sanitaire. De plus, il apparaít qu'une telle installation d'aisance et plus particulièrement l'équipage coulissant 10 portant la cuvette 6, ainsi que le dispositif de nettoyage 35, présentent une cinématique simple faisant intervenir un nombre restreint d'éléments présentant un coût faible de fabrication et garantissant une grande fiabilité de fonctionnement de l'ensemble.The method according to the invention ensures complete and effective cleaning of the bowl without soiling the sanitary room. In addition, it appears that such a facility and more particularly the sliding assembly 10 carrying the bowl 6 , as well as the cleaning device 35 , have simple kinematics involving a limited number of elements having a low cost manufacturing and guaranteeing a high operating reliability of the assembly.

    Selon une variante de l'installation 1, le guichet 8 est équipé d'un élément d'obturation 50 motorisé et piloté par l'unité de commande 20. L'élément d'obturation 50 peut, par exemple, être constitué par un volet roulant emmagasiné sur un tambour motorisé 51 raccordé par une ligne 52 à l'unité 20. Lors du cycle de nettoyage, l'unité 20 assure alors la fermeture de l'élément d'obturation 50 après rétraction de la cuvette 6 en position B. Ainsi, le local technique 4 se trouve isolé du local sanitaire 2 et aucune projection du liquide de nettoyage ne peut y intervenir. Après séchage du siège 7, l'unité 20 commande l'ouverture de l'élément d'obturation 50, puis la sortie de la cuvette 6.According to a variant of the installation 1 , the window 8 is equipped with a shutter element 50 motorized and controlled by the control unit 20 . The shutter element 50 may, for example, be constituted by a rolling shutter stored on a motorized drum 51 connected by a line 52 to the unit 20 . During the cleaning cycle, the unit 20 then ensures the closure of the closure element 50 after retraction of the bowl 6 in position B. Thus, the technical room 4 is isolated from the sanitary room 2 and no projection of the cleaning liquid can intervene there. After the seat 7 has dried, the unit 20 controls the opening of the closure element 50 , then the exit from the bowl 6 .

    Selon une autre variante de réalisation, le local sanitaire 2 est équipé d'une rampe d'aspersion 54 dirigée vers le sol 55 et raccordée à la source de liquide sous pression 39 par une canalisation 56 commandée par une électrovanne 57 qui est raccordée par une ligne 58 à l'unité de commande 20. Cette rampe 54 d'aspersion du sol 55 du local sanitaire est mise en action par l,unité 20 après sortie de l'utilisateur. Les eaux ruisselant sur le sol 55 sont récupérées par des moyens d'évacuation 59 disposés, par exemple, le long de la partie basse de la cloison 5.According to another alternative embodiment, the sanitary room 2 is equipped with a spraying boom 54 directed towards the ground 55 and connected to the source of pressurized liquid 39 by a pipe 56 controlled by a solenoid valve 57 which is connected by a line 58 at control unit 20 . This ramp 54 for spraying the floor 55 of the sanitary room is put into action by the unit 20 after the user exits. The water flowing on the ground 55 is recovered by evacuation means 59 arranged, for example, along the lower part of the partition 5 .

    Afin d'assurer un nettoyage automatique de cette partie basse de la cloison 5, cette dernière peut également être équipée d'une rampe d'aspersion 60 raccordée à la source de liquide sous pression 39 par une canalisation 61 commandée par une électrovanne 62. Après rétraction de la cuvette 6 et fermeture de l'élément d'obturation 50, l'unité de commande 20 pilote l'électrovanne 62, de manière à assurer l'aspersion de la partie basse de la cloison 5 située dans le local sanitaire 2 par la rampe 60. L'unité 20 peut également commander simultanément le fonctionnement de la rampe 54 en direction du sol 55. Ensuite, l'unité 20 interrompt l'aspersion de la cloison et du sol 55 et commande, par exemple, le fonctionnement de moyens de séchage 65 du local sanitaire, tels qu'un ventilateur dirigeant de l'air pulsé en direction du sol 55 et de la partie basse de la cloison 5.In order to ensure automatic cleaning of this lower part of the partition 5 , the latter can also be equipped with a spray boom 60 connected to the source of pressurized liquid 39 by a pipe 61 controlled by a solenoid valve 62 . After retraction of the bowl 6 and closing of the closure element 50 , the control unit 20 controls the solenoid valve 62 , so as to spray the lower part of the partition 5 located in the sanitary room 2 by ramp 60 . The unit 20 can also simultaneously control the operation of the ramp 54 in the direction of the ground 55 . Then, the unit 20 interrupts the spraying of the partition and the floor 55 and controls, for example, the operation of drying means 65 of the sanitary room, such as a fan directing forced air towards the floor 55 and the lower part of the partition 5 .

    Selon une forme de réalisation préférée, plus particulièrement illustrée à la fig. 4, les moyens de projection 36 sont constitués par un tourniquet 70 qui comporte au moins deux branches 71 s'étendant radialement à partir d'un arbre creux 72 d'alimentation et de rotation.According to a preferred embodiment, more particularly illustrated in FIG. 4 , the projection means 36 are constituted by a turnstile 70 which comprises at least two branches 71 extending radially from a hollow shaft 72 for supply and rotation.

    L'arbre 72 est porté par des moyens 73 de guidage en rotation selon un axe x-x', de préférence mais non exclusivement, sensiblement vertical, de raccordement à la canalisation 38. Conformément à l'exemple illustré, l'arbre 72 porte deux branches 71 opposées. De manière préférée, chaque branche 71 comporte, répartis sur sa longueur à partir de l'arbre 72, au moins un gicleur 74 d'aspersion du fond 61 de la cuvette, au moins un gicleur 75 d'aspersion des flancs 62 de la paroi interne de la cuvette et au moins un gicleur 76 d'aspersion du siège 7.The shaft 72 is carried by means 73 for guiding in rotation along an axis x-x ' , preferably but not exclusively, substantially vertical, for connection to the pipe 38 . In accordance with the example illustrated, the shaft 72 carries two opposite branches 71 . Preferably, each branch 71 comprises, distributed over its length from the shaft 72 , at least one nozzle 74 for spraying the bottom 6 1 of the bowl, at least one nozzle 75 for spraying the sides 6 2 of the internal wall of the bowl and at least one nozzle 76 for spraying the seat 7 .

    Selon la forme de réalisation illustrée, le gicleur 76, dit de siège, est disposé dans le prolongement de l'extrémité de la branche 71 opposée à l'arbre 72, cette extrémité étant recourbée vers le bas.According to the illustrated embodiment, the nozzle 76 , called seat, is arranged in the extension of the end of the branch 71 opposite the shaft 72 , this end being bent downwards.

    Dans une variante de réalisation de cette forme préférée, seule une partie des gicleurs 74, 75, 76 assure une mise en rotation du tourniquet 70 lors de son alimentation en liquide sous pression et de la projection de ce dernier en direction de la cuvette 6. De manière préférée, cette fonction motrice est assurée par les gicleurs 75 qui sont orientés vers les flancs 62 de la paroi interne de la cuvette et qui occupent une position intermédiaire sur chacune des branches 71. A cette fin, sur chaque branche 71, l'axe d'aspersion y1-y1' du gicleur 74 de fond est sensiblement parallèle à l'axe de rotation x-x' du tourniquet. De même, l'axe d'aspersion y2-y2' du gicleur 76 de siège est contenu dans un plan P radial contenant l'axe x-x'. Enfin, l'axe d'aspersion y3-y3' du gicleur 75 de flanc est contenu dans un plan P' perpendiculaire au plan radial P et présente une inclinaison dans un sens opposé au sens de rotation souhaité. De manière préférentielle, sur chaque branche 71, l'axe y3-y3' forme avec le plan radial P, un angle α compris entre 15° et 45°, comme le montre la fig. 5.In an alternative embodiment of this preferred form, only part of the nozzles 74 , 75 , 76 ensures rotation of the turnstile 70 during its supply of pressurized liquid and the projection of the latter in the direction of the bowl 6 . Preferably, this driving function is provided by the nozzles 75 which are oriented towards the sides 6 2 of the internal wall of the bowl and which occupy an intermediate position on each of the branches 71 . To this end, on each branch 71 , the spray axis y 1 -y 1 ' of the bottom nozzle 74 is substantially parallel to the axis of rotation x-x' of the turnstile. Similarly, the spray axis y 2 -y 2 ' of the seat nozzle 76 is contained in a radial plane P containing the axis x-x' . Finally, the spray axis y 3 -y 3 ' of the sidewall nozzle 75 is contained in a plane P' perpendicular to the radial plane P and has an inclination in a direction opposite to the desired direction of rotation. Preferably, on each branch 71 , the axis y 3 -y 3 ' forms with the radial plane P , an angle α between 15 ° and 45 °, as shown in FIG. 5 .

    Cette disposition de l'invention permet, lors de l'alimentation du tourniquet en fluide fourni à une pression comprise, de préférence mais non exclusivement, entre 5 et 15 bar environ, d'éviter avantageusement un emballement du tourniquet et d'assurer une rotation régulière de celui-ci. De plus, la présence et l'orientation des gicleurs 74 dirigés verticalement vers le fond 61 assurent un nettoyage particulièrement efficace de cette région de la cuvette, la plus exposée aux souillures.This arrangement of the invention makes it possible, during the supply of the turnstile with fluid supplied at a pressure comprised, preferably but not exclusively, between approximately 5 and 15 bar, to advantageously avoid runaway of the turnstile and to ensure rotation regular of it. In addition, the presence and orientation of the nozzles 74 directed vertically towards the bottom 6 1 ensure a particularly effective cleaning of this region of the bowl, the most exposed to soiling.

    L'invention n'est pas limitée aux exemples décrits et représentés, car diverses modifications peuvent y être apportées sans sortir de son cadre.The invention is not limited to the examples described and shown, since various modifications can be made without departing from its scope.
