Description

L'invention concerne un dispositif à éjection d'eau rétractable destiné à être integré dans la partie mediane et arrière d'un siège abattant de Water-closet pour permettre le lavage des parties intimes du corps humain.The invention relates to a retractable water ejection device intended to be integrated in the median and rear part of a water-closet folding seat to allow the washing of the intimate parts of the human body.

Dans ce domaine il est bien connu que l'utilisation du papier toilette n'est pas toujours suffisant et qu'un problème d'hygiène se pose suivant les personnes. D'où l'idée d'employer un moyen de lavage dans la cuvette même des W-C.In this field it is well known that the use of toilet paper is not always sufficient and that a hygiene problem arises according to the people. Hence the idea of using a washing device in the bowl even W-C.

Il existe aujourd'hui de nombreuses propositions qui dans l'ensemble sont assez complexes et coûteuses telles que les brevets européens 0293356 et 1605107 ainsi que les brevets WO 9615331 et WO 2006095492 . De ce fait l'utilisation de ces moyens est restreinte et à la limite ignorée du grand public.There are many proposals today that are quite complex and expensive, such as European patents 0293356 and 1605107 as well as patents WO 9615331 and WO 2006095492 . As a result, the use of these means is restricted and at the limit ignored by the general public.

Le document FR-A-2893644 décrit un siège W-C à douchette et bidet thermostatés équipé d'un vérin auto-nettoyant rétractable dans le siège de l'abattant. L'éjection du vérin est assurée par la pression de l'eau. Sa rétractation est assurée par ressort. Ce document est considéré comme l'état de la technique le plus proche. Le préambule de la revendication 1 est décrit dans ce document.The document FR-A-2893644 describes a toilet seat with shower and bidet thermostat equipped with a retractable self-cleaning cylinder in the seat of the flap. The ejection of the cylinder is ensured by the pressure of the water. Its retraction is ensured by spring. This document is considered to be the closest state of the art. The preamble of claim 1 is described in this document.

Le document EP-A-0293356 décrit un dispositif rétractable dans une cuvette de W-C.The document EP-A-0293356 discloses a retractable device in a toilet bowl.

Le document US-A-2003/0140407 décrit un abattant (siège plus couvercle) pourvu d'un système de nettoyage à commande électrique.The document US-2003/0140407 describes a flap (seat plus lid) with an electrically controlled cleaning system.

Le dispositif suivant l'invention permet d'améliorer la situation, à savoir, qu'il se présente d'abord sous la forme d'un kit pouvant être monté sur tout W-C existant. En effet, il suffit pour le bricoleur de remplacer l'abattant classique par l'abattant équipé du dispositif et d'insérer, par simple vissage sur l'arrivée d'eau du réservoir, un robinet en liaison avec le mécanisme.The device according to the invention makes it possible to improve the situation, namely, that it is first of all in the form of a kit that can be mounted on any existing W-C. Indeed, it is sufficient for the do-it-yourselfer to replace the classic flap by the flap equipped with the device and insert, by simply screwing on the water inlet of the tank, a valve in connection with the mechanism.

A première vue, le W-C équipé du dispositif se présente comme un W-C tout à fait ordinaire. Mais dans la mesure où l'utilisateur veut se laver, il suffit d'ouvrir un robinet pour déclencher, par la pression de l'eau, la sortie d'une buse qui en bout de course pulvérise de l'eau grâce à un éjecteur. A l'inverse, la simple fermeture du robinet arrête la pulvérisation et provoque la rétraction totale de la buse dans l'abattant. Les phases actives de rentrée et de sortie déclenchent un effet auto-nettoyant des pièces en jeu par simple effet d'écoulement d'eau secondaire simultané.At first glance, the W-C equipped with the device is presented as a W-C quite ordinary. But to the extent that the user wants to wash, just open a tap to trigger, by the pressure of the water, the exit of a nozzle which at the end of the race sprays water through an ejector . Conversely, simply closing the valve stops spraying and causes the total shrinkage of the nozzle in the flap. The active re-entry and exit phases trigger a self-cleaning effect of the parts involved by a simple simultaneous secondary water flow effect.

L'invention est décrite ci-après à l'aide d'un exemple et de références aux dessins joints dans lesquels :

  • la figure 1 est une vue de dessus représentant l'abattant équipé du dispositif,
  • la figure 2 est une vue de côté de l'abattant, sans le couvercle amovible, montrant une proéminence arrière ou une épaisseur supérieure de l'abattant,
  • la figure 3 est une vue en coupe du mécanisme de l'éjecteur en position rétracté, (robinet d'arrivée d'eau fermé),
  • la figure 4, même vue que la figure 3 mais avec le début d'ouverture du robinet et de la sortie de la buse,
  • la figure 5, même vue que les figures 3 et 4 avec ouverture du robinet et la sortie totale de la buse en position d'éjection de l'eau,
  • la figure 6, même vue que les figures 3, 4 et 5 avec le robinet fermé et la rétraction de la buse.
The invention is described below with the help of an example and references to the accompanying drawings in which:
  • the figure 1 is a top view showing the flap equipped with the device,
  • the figure 2 is a side view of the toilet seat, without the removable lid, showing a rear prominence or a greater thickness of the toilet seat,
  • the figure 3 is a sectional view of the mechanism of the ejector in retracted position, (water inlet valve closed),
  • the figure 4 , same view as the figure 3 but with the start of opening of the tap and the exit of the nozzle,
  • the figure 5 , even as the figures 3 and 4 with tap opening and the total outlet of the nozzle in the water ejection position,
  • the figure 6 , even as the figures 3 , 4 and 5 with the tap closed and the retraction of the nozzle.

Les figures 1 et 2 montrent l'ensemble kit du dispositif. Il se compose d'un mécanisme amovible (3) à buse (5) d'éjection d'eau (6) rétractable lié au travers des fixations pivotantes (29) à un robinet (4), à raccord tournant (31) lui-même lié par un tube souple (11) à un autre robinet (9) à dérivation inséré sur l'arrivée d'eau (10).The Figures 1 and 2 show the kit set of the device. It consists of a removable mechanism (3) with a retractable water ejection nozzle (5) (6) connected through the pivoting fasteners (29) to a valve (4), with a rotating union (31) itself. even connected by a flexible tube (11) to another tap (9) bypass inserted on the water inlet (10).

Le mécanisme amovible (3) est intégré dans la partie arrière (7) de l'abattant (1) faisant apparaître une proéminence (25) ou une épaisseur supérieure de l'abattant (33) pour absorber une inclinaison d'environ 25° de l'axe de la buse.The removable mechanism (3) is integrated in the rear part (7) of the flap (1) showing a protrusion (25) or a greater thickness of the flap (33) to absorb an inclination of about 25 ° of the axis of the nozzle.

L'emplacement du mécanisme dans l'abattant (1) s'opère dans un logement prévu à cet effet étanché en sa partie supérieure par un bouchon démontable (26).The location of the mechanism in the lid (1) takes place in a housing provided for this purpose sealed at its upper part by a removable cap (26).

Lors du montage de l'abattant, l'opérateur a le choix pour un robinet (4) ou un bouchon (30) monté à gauche ou à droite du W-C, ce qui permet de prendre en compte certaines contraintes, ne serait-ce que celle de la position d'arrivée de l'eau.When mounting the flap, the operator has the choice for a valve (4) or a plug (30) mounted on the left or right of the WC, which allows to take into account certain constraints, if only that of the arrival position of the water.

Dans le fonctionnement du dispositif, l'utilisateur ouvre le robinet (4) d'arrivée de l'eau qui commande l'auto-nettoyage (8) et le déplacement de la buse (5) de sortie d'eau vers le milieu de la cuvette (2) puis, en bout de course, l'arrêt de l'auto-nettoyage et la pulvérisation de l'eau grâce à un éjecteur (6). A l'inverse, la fermeture du robinet (4) commande simultanément l'arrêt de l'éjection d'eau et la rétraction de la buse (5) avec son auto-nettoyage (8) jusqu'à son escamotage total dans l'épaisseur arrière (7) du siège abattant (1). L'action de retour de la buse jusqu'à sa butée haute est assurée par un ressort (17).In the operation of the device, the user opens the water inlet valve (4) which controls the self-cleaning (8) and the displacement of the water outlet nozzle (5) towards the middle of the water. the bowl (2) then, at the end of the race, stopping the self-cleaning and spraying the water with an ejector (6). Conversely, the closure of the valve (4) simultaneously controls the stop of the water ejection and the retraction of the nozzle (5) with its self-cleaning (8) until its total retraction in the rear thickness (7) of the seat flap (1). The return action of the nozzle up to its high stop is provided by a spring (17).

Suivant les figures 3, 4 et 5 le mécanisme (3) comprend une arrivée d'eau commandée par un robinet (4), lequel est branché sur une enveloppe (12) fermée à son extrémité par une embase (23) et un bouchon démontable (26). A l'intérieur est montée une chemise amovible (13) étanchée à sa base par un joint torique (32) et maintenue par l'axe butée (28) verrouillé dans une encoche (27), dans laquelle se déplace un piston (16). La chemise distribue l'arrivée d'eau sous pression en deux positions, l'une haute (14) pour assurer le déplacement du piston (16) maintenu au préalable en position rentrée par un ressort (17) et l'autre basse (15) pour l'auto-nettoyage et l'éjection. Le piston dans son déplacement hors du tube fait apparaître une buse de sortie d'eau (5) équipée d'un éjecteur (6). En bout de course le piston est arrêté par un épaulement ou un circlips (21) placé sur sa tête. C'est dans cette position extrême que l'éjecteur (6) entre en action grâce à une chambre annulaire (18), formée autour de la tête du piston par deux joints toriques (19), qui se trouve en face de la position basse (15) de l'arrivée d'eau sous pression.Following the figures 3 , 4 and 5 the mechanism (3) comprises a water inlet controlled by a valve (4), which is connected to an envelope (12) closed at its end by a base (23) and a removable cap (26). Inside is mounted a removable jacket (13) sealed at its base by an O-ring (32) and held by the stopper shaft (28) locked in a notch (27), in which a piston (16) moves. . The jacket distributes the inlet of pressurized water in two positions, one high (14) to ensure the displacement of the piston (16) previously held in the retracted position by a spring (17) and the other low (15). ) for self-cleaning and ejection. The piston in its movement out of the tube shows a water outlet nozzle (5) equipped with an ejector (6). At the end of the stroke the piston is stopped by a shoulder or a circlip (21) placed on its head. It is in this extreme position that the ejector (6) comes into action thanks to an annular chamber (18) formed around the piston head by two O-rings (19), which is opposite the low position. (15) the inlet of water under pressure.

Pour éviter toute rotation possible de la buse (5) dans ses divers déplacements, une rainure (22) est pratiquée selon une génératrice dans laquelle s'emboîte l'extrémité d'un ergot (24) situé dans l'embase (23) de l'enveloppe (12).To avoid any possible rotation of the nozzle (5) in its various movements, a groove (22) is formed according to a generatrix in which the end of a lug (24) located in the base (23) of the envelope (12).

Le robinet (4) et le bouchon (30) peuvent être montés à droite ou à gauche de l'abattant. La buse (5) contient un éjecteur (6) démontable. Son étanchéité est obtenue par un joint torique. Le dispositif selon le mécanisme fait apparaître deux avantages importants :

  • Celui de la buse (5) rendue auto-nettoyante grâce à un jeu (8) établi entre la buse et l'embase (23) où s'échappe de l'eau en continu tant que la pression de l'eau est supérieure à la pression atmosphérique uniquement pendant les phases actives de sortie et de rentrée de celle-ci minimisant ainsi la consommation d'eau.
  • Le mécanisme amovible (3), facilement démontable, par sa simplicité ne comporte que trois pièces en mouvement, le ressort (17) et les joints toriques (19) acceptant l'alimentation en eau tempérée.
