Description

Installation de W.C. auto-nettoyante_d'une_cuvette_fixe_et de son siège_rotatif. Installation of self-cleaning WC of a fixed toilet and its rotary seat.
Un but de la présente invention est d'assurer automatiquement un nettoyage de l'intérieur d'une cuvette, et le nettoyage, la désinfection, le séchage du dessus d'un siège mobile accouplé à la cuvette.An object of the present invention is to automatically provide cleaning of the interior of a bowl, and cleaning, disinfection, drying of the top of a movable seat coupled to the bowl.
Un autre but vise à ce que l'installation soit la plus simple possible, sans basculement du siège ni de la cuvette.Another object is that the installation is as simple as possible, without tilting the seat or the bowl.
Un autre but vise à ce que le nettoyage et le séchage soient économiques et performants.Another aim is that cleaning and drying are economical and efficient.
Un autre but vise à augmenter la robustesse des W.C. par un siège rotatif et rigide solidement réuni à la cuvette sur son pourtour, contrairement aux abattants actuels bruyants et de fixation fragile.Another aim is to increase the robustness of the W.C. by a rotary and rigid seat securely joined to the bowl on its periphery, unlike the current noisy flaps and fragile fixing.
Un autre but vise à concevoir les moyens les mieux adaptés pour le nettoyage d'un siège rotatif en forme d'un disque rigide percé d'un grand trou oval et de diamètre sensiblement égal à la longueur des abattants actuels , de telle sorte que c e diamètre soit esthétiquement acceptable avec une avancée suffisante pour s'asseoir confortablement.Another aim is to design the most suitable means for cleaning a rotary seat in the form of a rigid disc pierced with a large oval hole and of diameter substantially equal to the length of the current flaps, so that this diameter is aesthetically acceptable with a sufficient projection to sit comfortably.
Un autre but vise à ce que le nettoyage de la face supérieure du siège soit exclusivement effectué par des moyens ne nécessitant pas de frottement de la dite face, donc sans brosse ni racloir disposés pour limiter l'étalement du liquide sur la partie arrière et annulaire du siège. Ces moyens, sans frottement, étant plus fiables, en permettant d'obtenir plus d'hygiène, plus de simplicité, et moins d'entretien.Another object is that the cleaning of the upper face of the seat is exclusively carried out by means not requiring friction of said face, therefore without brush or scraper arranged to limit the spreading of the liquid on the rear and annular part from the headquarters. These means, without friction, being more reliable, making it possible to obtain more hygiene, more simplicity, and less maintenance.
Un autre but vise à ce que l'installation soit inviolable en ne nésessitant pas de détecteur de présence, du fait d'une fermeture constante du poste de nettoyage-séchage, sans accessibilité pour l'usager, contrairement à l'ouverture béante d'une porte nécessaire à l'échange de sièges.Another object is that the installation is inviolable by not requiring a presence detector, due to a constant closure of the cleaning-drying station, without accessibility for the user, unlike the gaping opening a door necessary for the exchange of seats.
Un autre but vise à réaliser une installation esthétique et nette par l'utilisation d'une cuvette suspendue, et par l'encastrement des moyens de nettoyage de la cuvette et du siège derrière une cloison amovible formant un mur dorsal.Another object aims to achieve an aesthetic and clean installation by the use of a suspended bowl, and by embedding the means for cleaning the bowl and the seat behind a removable partition forming a back wall.
Un autre but vise à empécher l'engorgement de la cuvette, par un moyen de filtration et de stockage des objets pouvant boucher le siphon placé entre la cuvette et le tuyau de descente (chute) des eaux sales.Another aim is to prevent blockage of the bowl, by means of filtration and storage of objects which can clog the siphon placed between the bowl and the downpipe (fall) of dirty water.
Dans l'art antérieur apparaît l'invention PCT/FR.86 00099 du présent inventeur ayant l'avantage de répondre complètement ou partiellement aux buts des paragraphes 1, 2, 3. 4, 5, 7, 8, 9 , mais pas du tout au but du paragraphe 6.In the prior art, the invention PCT / FR.86 00099 of the present inventor appears, having the advantage of fully or partially meeting the aims of paragraphs 1, 2, 3. 4, 5, 7, 8, 9, but not of all for the purpose of paragraph 6.
Dans la présente invention, les performances de nettoyage, sans brosse, sont le fait d'une technique séquentielle à activation et confinement des liquides projetés sur un siège rotatif permettant, en outre, le nettoyage et le séchage en un temps très court, de l'ordre de 12 secondes; - une consommation d'eau, pour le nettoyage du siège, de l'ordre de 0,5 litre; - une consommation électrique de l'ordre de 0,004 Kwh. Ces performances sont le fait de la combinaison d'un siège rotatif, d'une projection d'air chaud concentré jusque très près sur le dessus du siège, d'une pulvérisation d'une solution chauffée par l'air chaud et agissant durant 6 secondes avant qu'intervienne une projection d'eau concentrée jusque très près sur le dessus du siège, l'air chaud continuant d'agir sur le siège après cette projection d'eau évacuant les salissures infiltrées par la solution chauffée.In the present invention, the cleaning performance, without brushing, is the result of a sequential technique with activation and confinement of the liquids sprayed on a rotary seat allowing, moreover, cleaning and drying in a very short time, of the 'order of 12 seconds; - a consumption of water, for cleaning the seat, of the order of 0.5 liters; - an electrical consumption of the order of 0.004 Kwh. These performances are due to the combination of a rotary seat, a projection of concentrated hot air up to very close to the top of the seat, a spraying of a solution heated by hot air and acting for 6 seconds before a concentrated water spray occurs very close to the top of the seat, the hot air continuing to act on the seat after this water spray removes dirt infiltrated by the heated solution.
On notera: - qu'aucun point de la surface supérieure du siège n'échappe aux projections liquides et d'air chaud, du fait de la rotation du siège; - que le confinement des projections liquides sur le siège, est complété en contrôlant l'étalement annulaire sur le siège par un ou deux rideaux d'air chaud. Mon procédé de basculement et d'échange de sièges, selon EP.83 400 757-7, a été repris par une société qui a choisi de ne pas utiliser de bras laveur rotatif, ni de séchage directement sur le siège. Les moyens utilisés sont 16 gicleurs en position fixe en face du siège arrêté dans le poste de nettoyage, et une projection diffuse d'air chaud dans le caisson de nettoyage.Note: - that no point on the upper surface of the seat escapes the liquid and hot air projections, due to the rotation of the seat; - that the confinement of liquid projections on the seat is completed by controlling the annular spreading on the seat by one or two curtains of hot air. My process of tilting and exchanging seats, according to EP.83 400 757-7, was taken over by a company which chose not to use a rotary washer arm, or to dry directly on the seat. The means used are 16 nozzles in a fixed position in front of the seat stopped in the cleaning station, and a diffuse projection of hot air in the cleaning box.
Ces moyens ont l'inconvénient de consommer 4 à 5 fois plus d'eau avec une pression de cinglage faible sur le siège, du fait de la dispersion en 16 gicleurs, et une consommation électrique 10 à 12 fois plus élevée du fait du séchage indirect. En outre, le nettoyage est aléatoire du fait qu'il n'est pas séquentiel et ne comprend pas de solution de nettoyage, mais uniquement un arrosage d'eau associée à un désinfectant, ce qui manque d'efficacité pour enlever les corps gras, y compris le sébum déposé par les fesses et dans lequel s'abritent les germes.These means have the disadvantage of consuming 4 to 5 times more water with a low pinging pressure on the seat, due to the dispersion in 16 nozzles, and an electrical consumption 10 to 12 times higher due to indirect drying. . In addition, cleaning is random because it is not sequential and does not include a cleaning solution, but only a sprinkling of water associated with a disinfectant, which lacks effectiveness in removing fatty substances, including the sebum deposited by the buttocks and in which the germs shelter.
Plus précisément, la présente invention est exposée avec des dessins décrits chronologiquement.More specifically, the present invention is exposed with drawings described chronologically.
La figure 1 est une vue de côté, partiellement en coupe de l'installation comprenant: - une cloison amovible 1 formant un mur dorsal; - des renforts longitudinaux 2 prévus pour rigidifier la cloison et faciliter la fixation d'éléments de l'installation, y compris la cuvette 3 supportant un siège rotatif 4; - un réservoir de chasse-d'eau 5 incluant un siphon 6, un détecteur de niveau 7, par exemple un flotteur, agissant sur un interrupteur électrique 8 connecté à une électrovanne 9, laquelle est en plus connectée à un relais électrique temporisé relié à un moyen de déclenchement d'un cycle de fonctionnement, de telle sorte que pour une durée déterminée après le dit déclenchement, 1 'électrovanne 9 alimente le réservoir 5 pour amorcer le siphon de vidage 6, le deuxième relais électrique étant assuré par l'interrupteur 8 dès la descente du flotteur 7; - une porte 10, supportée par la cloison, pour fermer l'orifice de chargement d'une cuve 11 fournissant une solution détergente et désinfectante pour le nettoyage du siège 4; - un vérin hydraulique à double effet 12 raccordé à une électrovanne et à une équerre 13 pour le basculement d'un panneau 14 suspendu à un axe 15, le panneau supportant et transportant des moyens de nettoyage tels qu'une buse 16 projetant une lame d'eau sous pression sur le siège, et un générateur électrique d'air chaud 17 raccordé à une buse 18; - un lave-mains, pouvant être utilisé au nettoyage de la cuvette, réalisé d'un gicleur 19 fixé au-dessus de la cuvette, et dans la cloison, pour diriger des jets d'eau; - un récepteur 20 dont le fond collecte une partie des liqides de nettoyage du siège pour les évacuer dans la cuvette, le fond supportant un pignon 21 engrenant avec le siège 4 qui comprend une couronne dentée; - une vis sans fin 22 en prolongement de l'arbre d'un moteur électrique 23 engrenant avec le pignon 21; - un ou plusieurs gicleurs 24 traversant la cloison et le côté arrière de la cuvette, et raccordés à une électrovanne pour compléter l'action de la chasse d'eau en dirigeant des jets d'eau sur les parties de la cuvette les plus exposées aux salissures, ces gicleurs pouvant être fixés sur l'intérieur du panneau basculant 14, dont l'un de ses côtés est représenté crevé pour voir les moyens 16 à 18; - un support 25, fixé sur le sol indépendamment de la cuvette, soutient et aligne la pipe de raccordement 26 entre la cuvette et le tuyau des eaux sales 27. Un programmateur, par exemple à minuterie, commande la séquence de projection d'air chaud, la séquence de projection de la solution de nettoyage, la séquence de projection de l'eau de rinçage, le cycle de fonctionnement étant déclenché directement par l'usager agissant sur un bouton, ou indirectement par l'ouverture et la fermeture de la porte du local de W.C., et/ou par un détecteur de présence.Figure 1 is a side view, partially in section of the installation comprising: - a removable partition 1 forming a back wall; - Longitudinal reinforcements 2 provided to stiffen the partition and facilitate the fixing of elements of the installation, including the bowl 3 supporting a rotary seat 4; - a flush tank 5 including a siphon 6, a level detector 7, for example a float, acting on an electrical switch 8 connected to a solenoid valve 9, which is additionally connected to a timed electrical relay connected to means for initiating an operating cycle, so that for a determined period after said initiation, the solenoid valve 9 supplies the reservoir 5 to initiate the drain siphon 6, the second electrical relay being provided by the switch 8 from the descent of the float 7; - A door 10, supported by the partition, to close the loading orifice of a tank 11 providing a detergent and disinfectant solution for cleaning seat 4; - a double-acting hydraulic cylinder 12 connected to a solenoid valve and a bracket 13 for tilting a panel 14 suspended from an axis 15, the panel supporting and transporting cleaning means such as a nozzle 16 projecting a blade d pressurized water on the seat, and an electric generator of hot air 17 connected to a nozzle 18; - A hand basin, which can be used for cleaning the bowl, made of a nozzle 19 fixed above the bowl, and in the partition, for directing water jets; - A receiver 20, the bottom of which collects part of the seat cleaning fluids to evacuate them into the bowl, the bottom supporting a pinion 21 meshing with the seat 4 which comprises a toothed crown; - a worm 22 in extension of the shaft of an electric motor 23 meshing with the pinion 21; - one or more nozzles 24 passing through the partition and the rear side of the bowl, and connected to a solenoid valve to complete the flushing action by directing jets of water on the parts of the bowl most exposed to soiling, these nozzles can be fixed on the inside of the tilting panel 14, one of its sides of which is shown to be punctured to see the means 16 to 18; a support 25, fixed on the ground independently of the bowl, supports and aligns the connection pipe 26 between the bowl and the dirty water pipe 27. A programmer, for example with a timer, controls the sequence of projection of hot air , the sequence of projection of the cleaning solution, the sequence of projection of the rinsing water, the operating cycle being triggered directly by the user acting on a button, or indirectly by the opening and closing of the door WC room, and / or by a presence detector.
La figure 2 est une vue en section de la cloison 1, fig.1, comprenant: - les renforts 2; - une ferrure 28 incluant des trous taraudés pour la fixation de la cuvette 3. La cloison sera obtenue par extrusion d'une matière plastique, les découpes et les perforations dans la cloison seront réalisées par une découpeuse à jet d'eau à très haute pression assisté par ordinateur.Figure 2 is a sectional view of the partition 1, fig.1, comprising: - the reinforcements 2; - a fitting 28 including threaded holes for fixing the bowl 3. The partition will be obtained by extrusion of a plastic material, the cutouts and the perforations in the partition will be made by a computer assisted very high pressure water jet cutter.
La figure 3 est une vue arrière d'une cuvette sans siphon. Cette cuvette 29 comprend: - une découpe 30 pour permettre l'engagement du pignon 21 et du fond du récepteur 20; - un racloir souple 31 pour arrêter l'eau pouvant s'étendre sous le siège en rotation; - des entailles 32 pour la fixation de la cuvette. Dans le but de simplifier la fabrication de la cuvette, celle-ci ne comprendra pas de côté arrière de fermeture. Dans ce cas, elle sera appliquée etancheement contre la cloison 1, fig.4, et avec le concours d'un joint 33 étendu à l'arrière de la cuvette, cette partie arrière comprenant l'orifice 34 de raccordement du tuyau 6 de la chassed'eau, cet orifice communiquant avec la fente 35 pour un arrosage périphérique de l'intérieur de la cuvette. La cuvette peut être réalisée en une matière moins lourde et moins cassante que la céramique, par exemple en une matière plastique, et l'intérieur de la cuvette peut comprendre un traitement de sa surface par un dépôt d'une matière lubrifiante, anti-adhérente, telle que le P.T.F.E. (Téflon) pour limiter ou empécher l'adhérence de la matière fécale. Nous retiendrons que les salissures sont fraîches, et donc faciles à enlever, du fait du nettoyage systématique après chaque usage de la cuvette.Figure 3 is a rear view of a bowl without a siphon. This bowl 29 includes: - a cutout 30 to allow engagement of the pinion 21 and the bottom of the receiver 20; - a flexible scraper 31 to stop the water which can extend under the rotating seat; - notches 32 for fixing the bowl. In order to simplify the manufacture of the bowl, it will not include a closing rear side. In this case, it will be applied tightly against the partition 1, fig. 4, and with the assistance of a joint 33 extended at the rear of the bowl, this rear part comprising the orifice 34 for connecting the pipe 6 of the flush, this orifice communicating with the slot 35 for peripheral irrigation of the interior of the bowl. The bowl can be made of a lighter and less brittle material than ceramic, for example a plastic material, and the inside of the bowl can include a treatment of its surface by depositing a lubricating, non-stick material , such as PTFE (Teflon) to limit or prevent the adhesion of fecal matter. We will remember that the dirt is fresh, and therefore easy to remove, due to the systematic cleaning after each use of the bowl.
La figure 4 est une vue de côté, partiellement en coupe, d'une combinaison de moyens incluant la cuvette 29 de la fig.3. Cette combinaison comprend: - la cloison 1 supportant le tuyau 6 de chasse-d'eau, le récepteur 20, un siphon 36 d'évacuation des contenus de la cuvette. Celle-ci est représentée crevée pour montrer que son côté arrière est formé spécifiquement par la cloison 1.Figure 4 is a side view, partially in section, of a combination of means including the bowl 29 of Fig.3. This combination includes: - the partition 1 supporting the flushing pipe 6, the receiver 20, a siphon 36 for discharging the contents of the bowl. This is shown punctured to show that its rear side is specifically formed by the partition 1.
La figure 5 est une vue de côté partielle et en coupe d'une installation de W.C. selon une variante de la fig.1, et comprenant: - la cloison 1 formant le mur dorsal du local de W.C.; - un récepteur 37 dont le fond a la même fonction que le récepteur 20, fig. 1 et 4; - un capot en forme d'un tiroir retourné 38, fermé sur le dessus et ouvert au-moins partiellement en dessous, supportant et transportant les moyens de nettoyage-séchage 16 à 18; - un vérin hydraulique à double effet 39 pour les mouvements d'avant en arrière du tiroir sur la partie arrière et annulaire du siège 4; - un bouchon 40 fermant l'orifice de chargement de la cuve 11, fig.1, placée, dans cette variante, près des moyens de nettoyage 16 à 18, ce bouchon appuyant sur un interrupteur électrique 41, de telle sorte que lorsque le bouchon n'est pas replacé, ou qu'il est saillant du dessus du tiroir, l'alimentation électrique générale est coupée et l'installation ne peut fonctionner; - une goupille saillante 42, en bout de l'arbre moteur 22 agit sur un contacteur 43 envoyant des impulsions électriques au programmateur comptant, ainsi, le nombre de tours d'entraînement du siège 4 Par le pignon 21, le contacteur pouvant être remplacé par l'association d'une source lumineuse et d'une photo-diode disposées de part et d'autre de la saillie tournante 42; - des gicleurs 24, dont l'un peut être placé, éventuellement, à l'intérieur du tiroir; - une cuvette 44, dont les contenus sont évacués par un grand trou 45 dans la cloison, sans siphon, fermé éventuellement par un clapet libre basculant, sous forme d'une plaque mince et légère 46 montée à rotation. Par ce dispositif de cuvette à clapet, avec un grand trou, sans siphon, on s'oppose à l'engorgement de la cuvette, contrairement aux cuvettes à siphon se bouchant facilement lors d'un encombrement important de papier ou d'autres objets jetés dans la cuvette. La chasse-d'eau, amenée par le conduit 6, participe à pousser le clapet 46 pour son basculement, permettant l'évacuation des contenus de la cuvette qui sont dirigés dans un panier de manutention 47 incluant une grille formée de lames 48 espacées et inclinées longitudinalement pour filtrer les objets jetés dans la cuvette, et de telle sorte que les objets volumineux, susceptibles de boucher le siphon de sol 49, soient arrêtés par la grille et chassés à une extrémité 50 du panier. La figure 6 est une vue en élévation et partiellement en coupe, détaillant des moyens de la fig.5, et comprenant: - le siège rotatif 4 incluant des segments circulaires 51, en une matière glissante, pour l'accouplement du siège à l'une des cuvettes 3, 29, 44, les segments étant vissés en-dessous du siège, et par l'arrière de la cuvette, en tournant le siège au fur et à mesure de la fixation d'un segment; - le tiroir 38 représenté crevé pour montrer les moyens de nettoyage-séchage qu'il transporte. Ces moyens comprennent: - le générateur électrique 17, tel qu'un petit sèche-cheveux à ventilation forcée, incluant deux buses (18), (18a) concentrant de l'air chaud jusque très près sur le dessus du siège; - deux buses (16), (16a) concentrant un liquide jusque très près sur le dessus du siège; - la cuve 11 fournissant un faible débit d'une solution de nettoyage s'écoulant dans la buse 18 pour être chauffée et pulvérisée sur le dessus du siège. Les buses (16), (16a) et (18), (18a) coopèrent pour confiner les liquides sur la partie arrière et annulaire du siège, en limitant l'étalement annulaire, de telle sorte qu'aucun liquide ne s'écoule à l'extérieur de la cuvette, du fait de la rotation du siège, et sans nécessiter de moyens de frottement tels qu'une brosse et/ou un racloir. Cette technique séquentielle de nettoyage, à activation et confinement des liquides projetés sur le siège, est particulièrement performante en ne nécessitant aucun moyen de frottement sur le dessus du siège , tout en assurant un nettoyage sérieux, économique, rapide, par des moyens simples, hygiéniques. Dans cet exemple de coopération des buses (16), (16a) et (18), (18a), le siège peut tourner dans un sens quelconque.Figure 5 is a partial side view in section of a WC installation according to a variant of Fig.1, and comprising: - the partition 1 forming the back wall of the WC room; - A receiver 37 whose bottom has the same function as the receiver 20, fig. 1 and 4; - A cover in the form of an inverted drawer 38, closed on top and open at least partially below, supporting and transporting the cleaning-drying means 16 to 18; - a double-acting hydraulic cylinder 39 for the movements of the drawer back and forth on the rear and annular part of the seat 4; - A plug 40 closing the loading opening of the tank 11, fig.1, placed, in this variant, near the cleaning means 16 to 18, this plug pressing on an electric switch 41, so that when the plug is not replaced, or is protruding from the top of the drawer, the general power supply is cut and the installation cannot function; - a protruding pin 42, at the end of the motor shaft 22 acts on a contactor 43 sending electrical pulses to the programmer counting, thus, the number of seat drive turns 4 By the pinion 21, the contactor can be replaced by the combination of a light source and a photo-diode arranged on either side of the rotating projection 42; - Nozzles 24, one of which can be placed, if necessary, inside the drawer; - A bowl 44, the contents of which are discharged through a large hole 45 in the partition, without siphon, optionally closed by a free tilting valve, in the form of a thin and light plate 46 mounted for rotation. By this valve bowl device, with a large hole, without siphon, we oppose the engorgement of the bowl, unlike siphon bowls that get easily clogged when there is a lot of paper or other objects thrown away in the bowl. The flush, brought by the conduit 6, participates in pushing the valve 46 for its tilting, allowing the evacuation of the contents of the bowl which are directed into a handling basket 47 including a grid formed of spaced blades 48 and longitudinally inclined to filter the objects thrown into the bowl, and so that bulky objects, capable of clogging the floor drain 49, are stopped by the grid and expelled at one end 50 of the basket. Figure 6 is an elevational view partially in section, detailing the means of fig.5, and comprising: - the rotary seat 4 including circular segments 51, in a sliding material, for coupling the seat to the one of the bowls 3, 29, 44, the segments being screwed below the seat, and from the rear of the bowl, by turning the seat as and when fixing a segment; - The drawer 38 shown punctured to show the cleaning-drying means it carries. These means include: - the electric generator 17, such as a small hair dryer with forced ventilation, including two nozzles (18), (18a) concentrating hot air very close to the top of the seat; - two nozzles (16), (16a) concentrating a liquid as close as possible to the top of the seat; - The tank 11 providing a low flow rate of a cleaning solution flowing in the nozzle 18 to be heated and sprayed on the top of the seat. The nozzles (16), (16a) and (18), (18a) cooperate to confine the liquids on the rear and annular part of the seat, limiting the annular spreading, so that no liquid flows out. the outside of the bowl, due to the rotation of the seat, and without requiring friction means such as a brush and / or a scraper. This sequential cleaning technique, with activation and confinement of the liquids sprayed on the seat, is particularly effective by not requiring any means of friction on the top of the seat, while ensuring a serious, economical, rapid cleaning, by simple, hygienic means. . In this example of cooperation of the nozzles (16), (16a) and (18), (18a), the seat can rotate in any direction.
Le figure 7 est une vue en élévation, complémentaire de la fig.6, pour montrer un autre exemple de coopération de buses projetant un liquide concentré jusque très près sur le dessus du siège, et projetant de l'air concentré jusque très près sur le dessus du siège. Dans cet exemple de coopération, le siège ne tournera pas dans un sens quelconque, mais dans le sens allant de la buse de liquide 16 à la buse d'air 18a. La buse 16 comprend une succession de trous projetant des jets liquides 52 sur un plan incliné 53, de manière à fournir une lame d'eau cinglant le dessus du siège pour évacuer les salissures infiltrées par la solution pulvérisée et activée par l'air chaud.FIG. 7 is an elevational view, complementary to FIG. 6, to show another example of cooperation of nozzles projecting a concentrated liquid as far as very close to the top of the seat, and projecting concentrated air as far as very close to the above the seat. In this example of cooperation, the seat will not rotate in any direction, but in the direction going from the liquid nozzle 16 to the air nozzle 18a. The nozzle 16 comprises a succession of holes projecting liquid jets 52 onto an inclined plane 53, so as to provide a blade of water that lashes the top of the seat to evacuate the dirt infiltrated by the sprayed solution and activated by the hot air.
La figure 8 est une vue, à la loupe, d'un détail de la fig.7 et comprenant: - un contacteur électrique à lamelles souples 54, fixé sur la buse (18a) pour que les électrovannes fournissant les liquides de nettoyage ne soient sous tension électrique que lorsque les lamelles 54 se touchent sous l'action de la ventilation du générateur 17. L'induction électrique émise par le fonctionnement du ventilateur 17, pourrait permettre de fermer temporairement le circuit électrique des dites électrovannes connectées au programmateur. Par ces moyens, on s'assure que les liquides ne pourront s'écouler sur le siège en l'absence d'un ou deux rideaux d'air nécessaire à empécher qu'une partie de ces liquides ne s'écoule en dehors de la cuvette et du récepteur 20, 37.FIG. 8 is a view, with a magnifying glass, of a detail of FIG. 7 and comprising: - an electrical contactor with flexible strips 54, fixed on the nozzle (18a) so that the solenoid valves supplying the cleaning liquids are not under electric voltage only when the slats 54 touch under the action of the ventilation of the generator 17. The electric induction emitted by the operation of the fan 17, could make it possible to temporarily close the electric circuit of said solenoid valves connected to the programmer. By these means, it is ensured that liquids cannot flow on the seat in the absence of one or two air curtains necessary to prevent part of these liquids from flowing outside the bowl and receiver 20, 37.
La figure 9 est une vue en élévation et en coupe de la cuve 11 contenant des moyens de réalisation et de dosage d'une solution de nettoyage, et comprenant: - un produit chimique solide et soluble, sous la forme d'un empilement de tubes 55 chargés un à un dans la cuve 11; - un tourniquet 56, raccordé à une électrovanne temporisée, pour un arrosage circulaire à la base du dit empilement, arrosage entraînant une érosion et une dissolution progressive de ces tubes; - un conduit 57 raccordé à la buse 18 du générateur d'air chaud 17, fig.6 et 7, de manière à chauffer et à pulvériser la dite solution.Figure 9 is an elevational and sectional view of the tank 11 containing means for producing and dosing a cleaning solution, and comprising: - a solid and soluble chemical, in the form of a stack of tubes 55 loaded one by one into the tank 11; - A turnstile 56, connected to a timed solenoid valve, for circular watering at the base of said stack, watering causing erosion and progressive dissolution of these tubes; - A conduit 57 connected to the nozzle 18 of the hot air generator 17, fig.6 and 7, so as to heat and spray said solution.
La figure 10 est une vue en élévation et en coupe de la cuve 11 contenant des moyens de réalisation et de dosage d'une solution de nettoyage, et selon une variante de la fig.9. Cette variante comprend: - les tubes solubles 55; - un tuyau 58 d'amené d'eau raccordé à une électrovanne temporisée; - un siphon 59 raccordé à la buse 18 du générateur d'air chaud, et prélevant,à chaque cycle de fonctionnement, une partie de la solution; - une grille centrale 60 empéchant l'effondrement des tubes 33 ramolis par leur trempage dans la cuve.Figure 10 is an elevational and sectional view of the tank 11 containing means for producing and dosing a cleaning solution, and according to a variant of Fig.9. This variant includes: - the soluble tubes 55; - A water supply pipe 58 connected to a timed solenoid valve; - a siphon 59 connected to the nozzle 18 of the hot air generator, and taking, at each operating cycle, part of the solution; - A central grid 60 preventing the collapse of the tubes 33 softened by their soaking in the tank.
Nous noterons que lors de l'avancement du tiroir 38, ouvert partiellement en dessous, cette ouverture est masquée par la partie arrière et annulaire du siège. Les moyens de nettoyage et de séchage (16) à (18a) sont donc enfermés en permanence et inaccessibles par l'usager. We will note that during the advancement of the drawer 38, partially open below, this opening is hidden by the rear and annular part of the seat. The cleaning and drying means (16) to (18a) are therefore permanently locked and inaccessible by the user.
