Description

La présente invention concerne un robinet de remplissage d'une cuve de chasse de toilettes comprenant un corps de robinet, une prise d'air règlementaire et une tubulure de remplissage coopérant avec un obturateur.The present invention relates to a filling valve for a toilet flush tank comprising a valve body, a regulatory air intake and a filling tube cooperating with a shutter.

Les robinets de remplissage d'une cuve de chasse fonctionnent généralement par une commande à flotteur telle que le déplacement du flotteur en fin de remplissage commande un poussoir appliquant l'obturateur contre une extrémité de la tubulure de remplissage interrompant ainsi le débit d'eau.The filling valves of a flush tank generally operate by a float control such that the movement of the float at the end of filling controls a pusher applying the shutter against one end of the filling tube thus interrupting the flow of water.

En cas de dépression accidentelle dans le réseau d'alimentation d'eau, il peut se produire une aspiration de l'eau contenue dans un réservoir de toilette qui pourrait alors rejoindre le réseau d'alimentation d'eau.In the event of an accidental depression in the water supply network, there may be a suction of the water contained in a toilet tank which could then join the water supply network.

Pour prévenir ce phénomène, la réglementation sanitaire liée aux dispositifs de toilettes impose la présence d'une prise d'air pour qu'une dépression qui se produirait dans le réseau d'alimentaire n'entraine pas d'aspiration de l'eau présente dans un réservoir de toilette.To prevent this phenomenon, the sanitary regulations linked to the toilet devices impose the presence of an air intake so that a depression which would occur in the food network does not cause suction of the water present in a toilet tank.

Or, il se trouve que, lors du remplissage du réservoir, la prise d'air peut générer un sifflement qui présente un fort désagrément pour les usagers.However, it turns out that, when filling the tank, the air intake can generate a whistling noise which is very unpleasant for users.

Certains dispositifs visent à remédier à cet inconvénient en prévoyant un système d'obturation mécanique de la prise d'air, lors du remplissage du réservoir.Certain devices aim to remedy this drawback by providing a mechanical shutter system for the air intake, when filling the tank.

Néanmoins, ce système d'obturation mécanique, composé de plusieurs pièces, augmente conséquemment le cout total du robinet de remplissage auquel il est incorporé. On connait, par exemple, le document GB 2 233 680 qui décrit un dispositif de silencieux pour un robinet de chasse comprenant un tube de remplissage présentant plusieurs perçages qui débouchent dans un réservoir. Le réservoir présente des ouvertures qui permettent une aspiration d'air. Ce dispositif ne permet pas une obturation efficace des prises d'air. En effet, les perçages du tube ne permettent pas de capter une quantité d'eau suffisante pour obturer les prises d'air.However, this mechanical shutter system, composed of several parts, consequently increases the total cost of the filling valve in which it is incorporated. We know, for example, the document GB 2,233,680 which describes a silencer device for a flush valve comprising a filling tube having several holes which open into a tank. The tank has openings which allow air to be drawn in. This device does not allow effective sealing of the air intakes. In fact, the holes in the tube do not allow a sufficient quantity of water to be captured to close off the air intakes.

Il est aussi connu du document US 2 491 131 d'utiliser un robinet de chasse présentant deux tuyaux de remplissage : un tuyau primaire et un tuyau secondaire, qui ne sont pas positionnés aux mêmes niveaux. Ce robinet présente un mécanisme complexe utilisant un grand nombre de pièces.It is also known from the document US 2,491,131 use a flush valve with two filling pipes: a primary pipe and a secondary pipe, which are not positioned at the same levels. This tap has a complex mechanism using a large number of parts.

Dans ce contexte, un but de la présente invention est de proposer un robinet de remplissage d'une cuve de chasse de toilettes qui permette l'obturation de la prise d'air réglementaire, en utilisant un nombre réduit de pièces, par rapport aux dispositifs de l'art antérieur.In this context, an object of the present invention is to provide a valve for filling a toilet flush tank which allows the closure of the regulatory air intake, using a reduced number of parts, compared to the devices. of the prior art.

Selon une définition générale, l'invention concerne un robinet de remplissage d'une cuve de chasse de toilettes qui comprend,

  1. (i) un corps dans lequel est ménagée une chambre, connectée à un tube d'arrivée d'eau et à un tube de remplissage d'une cuve de chasse dans lequel est pratiquée une ouverture formant une prise d'air,
  2. (ii) un réservoir (30) disposé en regard de l'ouverture (35) conçu pour être rempli lors du passage de l'eau jusqu'à immerger l'ouverture (35) et pour être vidé et libérer l'ouverture (35) lors de la fermeture du robinet de remplissage.
According to a general definition, the invention relates to a valve for filling a toilet flush tank which comprises,
  1. (i) a body in which a chamber is formed, connected to a water inlet tube and to a filling tube of a flush tank in which an opening forming an air intake is made,
  2. (ii) a reservoir (30) arranged opposite the opening (35) designed to be filled during the passage of water until immersing the opening (35) and to be emptied and release the opening (35 ) when closing the filling tap.

Le positionnement de l'ouverture formant prise d'air, dans un réservoir communiquant avec le tube de remplissage, permet au robinet de commande selon l'invention de réaliser l'obturation de la prise d'air en utilisant un nombre réduit de pièces. En effet, cette disposition technique permet l'obturation hydraulique de la prise d'air, en immergeant l'ouverture positionnée dans le réservoir.The positioning of the opening forming an air intake, in a reservoir communicating with the filling tube, allows the control valve according to the invention to shut off the air intake using a reduced number of parts. Indeed, this technical arrangement allows the hydraulic plugging of the air intake, by immersing the opening positioned in the tank.

En effet, l'ouverture, présente entre le tube de remplissage et le réservoir, permet à l'eau circulant dans le tube de remplissage de pénétrer dans le réservoir pour le remplir et immerger le perçage formant prise d'air.Indeed, the opening, present between the filling tube and the reservoir, allows the water circulating in the filling tube to enter the reservoir to fill it and immerse the bore forming air intake.

Il s'agit là d'un point important de l'invention. L'utilisation d'un réservoir, remplit lors de l'ouverture du robinet de commande, permet au dispositif selon l'invention d'utiliser un faible nombre de pièces pour obturer l'ouverture formant prise d'air.This is an important point of the invention. The use of a reservoir, filled during the opening of the control valve, allows the device according to the invention to use a small number of parts to close the opening forming an air intake.

De plus, le robinet comprend un carter engagé sur le tube de remplissage, le carter présentant une partie annulaire qui délimite le réservoir avec le tube de remplissage, et une partie tubulaire qui plonge dans la cuve de chasse de toilettes.In addition, the valve comprises a casing engaged on the filling tube, the casing having an annular part which delimits the reservoir with the filling tube, and a tubular part which plunges into the toilet flush tank.

La partie annulaire du carter délimite avec le corps une surverse par laquelle s'échappe l'eau excédentaire du réservoir.
La surverse permet avantageusement à l'eau excédentaire du réservoir de s'échapper vers la cuve de chasse, et forme une prise d'air avec l'atmosphère extérieur.The annular part of the housing defines with the body an overflow through which escapes the excess water from the tank.
The overflow advantageously allows excess water from the tank to escape to the flush tank, and forms an air intake with the outside atmosphere.

Ainsi le réservoir selon l'invention est peu volumineux et présente un encombrement réduit.Thus the tank according to the invention is not very bulky and has a reduced bulk.

Selon un mode de réalisation préféré, le tube de remplissage présente au moins un biseau, ou une forme similaire, positionné à proximité de l'ouverture. Le biseau est conçu pour orienter une portion du liquide circulant dans le tube de remplissage, au travers de l'ouverture, dans le réservoir.According to a preferred embodiment, the filling tube has at least one bevel, or a similar shape, positioned near the opening. The bevel is designed to orient a portion of the liquid circulating in the filling tube, through the opening, in the reservoir.

De plus, le tube de remplissage peut comprendre au moins une surface oblique par rapport à l'axe longitudinal du tube de remplissage, conçue pour freiner le liquide circulant dans le tube de remplissage.In addition, the filling tube may include at least one surface oblique to the longitudinal axis of the filling tube, designed to brake the liquid circulating in the filling tube.

La surface oblique permet de réduire le débit du liquide circulant dans le tube de remplissage pour faciliter le remplissage du réservoir.The oblique surface makes it possible to reduce the flow rate of the liquid circulating in the filling tube to facilitate the filling of the tank.

D'autres caractéristiques et avantages se dégageront de la description qui va suivre en regard des dessins annexés qui représentent, à titre d'exemple non limitatif, une forme de réalisation de l'invention, dans lesquels :

  • La figure 1 est une vue en perspective du robinet selon l'invention ;
  • La figure 2 est une vue en coupe de face du robinet selon l'invention, lorsque l'obturateur est en position ouverte ;
  • La figure 3 est une vue en coupe C-C, de coté, du robinet selon l'invention, lorsque l'obturateur est en position ouverte ;
Other characteristics and advantages will emerge from the description which follows with reference to the appended drawings which represent, by way of nonlimiting example, an embodiment of the invention, in which:
  • The figure 1 is a perspective view of the valve according to the invention;
  • The figure 2 is a front sectional view of the valve according to the invention, when the shutter is in the open position;
  • The figure 3 is a sectional view CC, from the side, of the valve according to the invention, when the shutter is in the open position;

La figure 1 représente un robinet de commande 1 du remplissage d'un réservoir chasse.The figure 1 represents a control valve 1 for filling a flush tank.

Le robinet de remplissage 1 est conçu pour être positionné dans une cuve de chasse d'un dispositif de toilettes pour commander le remplissage de ladite cuve de chasse.The filling valve 1 is designed to be positioned in a flush tank of a toilet device to control the filling of said flush tank.

En outre, le dispositif de toilettes comprend par ailleurs des moyens de vidage, éventuellement à deux positions, qui autorisent le vidage du contenu de la cuve de chasse dans une cuvette. Le robinet de remplissage 1 a pour fonction de commander le remplissage de la cuve de chasse, jusqu'à son arrêt.In addition, the toilet device also comprises emptying means, possibly in two positions, which allow the emptying of the contents of the flush tank into a bowl. The filling valve 1 has the function of controlling the filling of the flush tank, until it stops.

Pour cela, le robinet de remplissage 1 comprend un corps 2 qui présente une tubulure d'arrivée d'eau 4. La tubulure d'arrivée d'eau 4 est destinée à être reliée à un réseau d'eau, pour alimenter le robinet de commande 1 en eau. En outre, un carter 6 recouvre partiellement le corps 2.For this, the filling tap 1 comprises a body 2 which has a water inlet pipe 4. The water inlet pipe 4 is intended to be connected to a water network, to supply the tap command 1 in water. In addition, a casing 6 partially covers the body 2.

De plus, le robinet de remplissage 1 comprend un mécanisme de commande dont la fonction est de piloter l'ouverture et la fermeture du robinet de remplissage 1, selon le niveau d'eau présent dans la cuve de chasse.In addition, the filling valve 1 comprises a control mechanism whose function is to control the opening and closing of the filling valve 1, according to the level of water present in the flush tank.

Selon le mode de réalisation ici présenté, le mécanisme de commande comprend un flotteur 20 relié à une première extrémité d'un levier 8.According to the embodiment presented here, the control mechanism comprises a float 20 connected to a first end of a lever 8.

Le flotteur 20 est fixé au levier 8 au moyen d'une vis de réglage 21, comme cela est illustré sur la figure 1. La rotation de la vis de réglage 21 permet d'ajuster la hauteur du flotteur 20 dans une cuve de chasse.The float 20 is fixed to the lever 8 by means of an adjustment screw 21, as illustrated in the figure 1 . The rotation of the adjusting screw 21 makes it possible to adjust the height of the float 20 in a flush tank.

Dans l'exemple représenté, le carter 6 présente une partie tubulaire 6b sur laquelle coulisse le flotteur 20. La partie tubulaire 6b du carter 6 assure ainsi une fonction de guide en translation du flotteur 20.In the example shown, the casing 6 has a tubular part 6b on which the float 20 slides. The tubular part 6b of the casing 6 thus performs a function of guide in translation of the float 20.

Le levier 8 présente une seconde extrémité qui forme une came 9.The lever 8 has a second end which forms a cam 9.

La came 9 est liée en rotation à une chape 10 fixée au corps 2.The cam 9 is linked in rotation to a yoke 10 fixed to the body 2.

Ainsi, le mécanisme de commande ici présenté est de type hydraulique, néanmoins, le robinet de remplissage 1 peut comprendre d'autres types de mécanismes de commande, comme par exemple un mécanisme de type mécanique.Thus, the control mechanism presented here is of the hydraulic type, however, the filling valve 1 can include other types of control mechanisms, such as for example a mechanical type mechanism.

On peut se reporter à la figure 2, qui est une vue en coupe du robinet, pour apprécier le fonctionnement du robinet de commande 1.We can refer to the figure 2 , which is a sectional view of the valve, to assess the operation of the control valve 1.

Le corps 2 présente schématiquement un tube d'arrivée d'eau 4, une chambre 3 et un tube de remplissage 7.The body 2 schematically presents a water inlet tube 4, a chamber 3 and a filling tube 7.

Le tube de remplissage 7 permet d'introduire l'eau issue du tube d'arrivée d'eau, dans la partie basse d'une cuve de chasse pour éviter les bruits liés à l'écoulement d'eau sous pression.The filling tube 7 makes it possible to introduce the water coming from the water inlet tube into the lower part of a flush tank to avoid the noises linked to the flow of water under pressure.

Selon le mode de réalisation ici présenté, un obturateur 27 est positionné dans la chambre 3. L'obturateur 27 est commandé avec la came 9 du levier 8. L'obturateur 27 comprend une tête 28 qui possède un pointeau conique pour centrer la tête 28 par rapport au tube de remplissage 7. La tête 28 est destinée à obturer une extrémité supérieure du tube de remplissage pour interdire l'écoulement de l'eau dans le tube de remplissage 7.According to the embodiment presented here, a shutter 27 is positioned in the chamber 3. The shutter 27 is controlled with the cam 9 of the lever 8. The shutter 27 comprises a head 28 which has a conical needle to center the head 28 with respect to the filling tube 7. The head 28 is intended to close an upper end of the filling tube to prevent the flow of water in the filling tube 7.

Tel que cela est représenté sur la figure 2, le robinet de remplissage 1 comprend un réservoir 30.As shown in the figure 2 , the filling tap 1 comprises a reservoir 30.

Dans l'exemple représenté, le réservoir 30 est délimité par le carter 6 et par le corps 2.In the example shown, the reservoir 30 is delimited by the casing 6 and by the body 2.

Pour cela, le carter 6 possède une paroi annulaire 6a. Ainsi, l'engagement du carter 6 sur le tube de remplissage 7 permet de former le réservoir 30.For this, the casing 6 has an annular wall 6a. Thus, the engagement of the casing 6 on the filling tube 7 makes it possible to form the reservoir 30.

Il est à noter que le réservoir 30 formé par la paroi annulaire 6a n'est pas étanche. En effet, le réservoir 30 est doté d'une surverse 39 et un orifice de vidage 41It should be noted that the reservoir 30 formed by the annular wall 6a is not sealed. Indeed, the tank 30 is provided with an overflow 39 and a drain orifice 41

Un orifice 40 débouche à l'extérieur du robinet de remplissage 1, dans la cuve de chasse, pour former une prise d'air avec l'atmosphère extérieure du robinet de remplissage 1.An orifice 40 opens to the outside of the filling valve 1, in the flushing tank, to form an air intake with the external atmosphere of the filling valve 1.

De plus, la surverse 39 permet à l'eau excédentaire dans le réservoir 30, de s'échapper dans la cuve de chasse.In addition, the overflow 39 allows the excess water in the tank 30 to escape into the flush tank.

Comme on peut le voir sur la figure 3, il est prévu que le réservoir 30 soit mis en communication avec le tube de remplissage 7. Le tube de remplissage 7 présente une ouverture 35 qui débouche dans le réservoir 30.As we can see on the figure 3 , provision is made for the reservoir 30 to be placed in communication with the filling tube 7. The filling tube 7 has an opening 35 which opens into the reservoir 30.

L'ouverture 35 débouche à proximité d'une partie inférieure de la paroi annulaire 6a.The opening 35 opens near a lower part of the annular wall 6a.

Une portion de l'ouverture 35 est délimitée par un biseau 36.A portion of the opening 35 is delimited by a bevel 36.

Le biseau 36 est conçu pour orienter une partie du flux de liquide qui traverse le tube de remplissage 7, vers le réservoir 30.The bevel 36 is designed to direct part of the liquid flow which passes through the filling tube 7, towards the reservoir 30.

Comme représenté sur la figure 3, une extrémité inférieure du tube de remplissage 7 présente une surface oblique 37 par rapport à un axe longitudinal A du tube de remplissage 7.As shown in the figure 3 , a lower end of the filling tube 7 has an oblique surface 37 with respect to a longitudinal axis A of the filling tube 7.

Le fonctionnement du robinet de remplissage 1 est le suivant.The operation of the filling valve 1 is as follows.

Il est précisé que la description qui va suivre part d'une situation dans laquelle le robinet de commande 1 est ouvert et positionné dans une cuve de chasse d'un dispositif de toilettes.It is specified that the description which follows will start from a situation in which the control tap 1 is open and positioned in a flush tank of a toilet device.

En position ouverte, l'obturateur 27 autorise la circulation d'un fluide au travers du tube de remplissage 7.In the open position, the shutter 27 authorizes the circulation of a fluid through the filling tube 7.

L'eau issue du tube d'arrivée d'eau 4 remplit la chambre 3 et s'introduit dans le tube de remplissage 7 pour être, ensuite, déversée dans la cuve de chasse.The water from the water inlet tube 4 fills the chamber 3 and is introduced into the filling tube 7 to be, then, poured into the flush tank.

Lors de l'écoulement de l'eau dans le tube de remplissage 7, la surface oblique 37 réduit le débit de l'eau circulant dans le tube de remplissage 7.When the water flows through the filling tube 7, the oblique surface 37 reduces the flow of water circulating in the filling tube 7.

De plus, le biseau 36 permet d'orienter une partie de l'eau, ralentie par la surface oblique 37, au travers de l'ouverture 35, dans le réservoir 30.In addition, the bevel 36 makes it possible to orient part of the water, slowed down by the oblique surface 37, through the opening 35, in the reservoir 30.

L'eau ainsi orientée, par le biseau 36, remplit le réservoir 30.The water thus oriented, by the bevel 36, fills the reservoir 30.

Il s'agit là d'un point important de l'invention. En effet, l'immersion du réservoir 30 durant le remplissage de la cuve de chasse permet d'obturer hydrauliquement la prise d'air et permet ainsi de s'affranchir des couteux, et volumineux, mécanismes d'obturation mécanique de l'art antérieur.This is an important point of the invention. In fact, the immersion of the reservoir 30 during filling of the flushing tank makes it possible to hydraulically close the air intake and thus makes it possible to get rid of the expensive, and bulky, mechanical shutter mechanisms of the prior art. .

En cas de trop plein du réservoir 30, l'eau excédentaire s'échappe par la surverse 39, dans la cuve de chasse.In the event of overflow of the reservoir 30, the excess water escapes through the overflow 39, into the flush tank.

Selon le mode de réalisation ici présenté, au fur et à mesure du remplissage de la cuve de chasse, le flotteur 20 coulisse le long du carter 6 et exerce un effort sur le levier 8. Sous la poussée du flotteur 20, le levier 8 pivote dans la chape 10. En pivotant, la came 9 du levier 8 fait passer l'obturateur 27 en position fermée dans laquelle il obture le tube de remplissage 7.According to the embodiment presented here, as the filling of the flush tank, the float 20 slides along the casing 6 and exerts a force on the lever 8. Under the thrust of the float 20, the lever 8 pivots in the yoke 10. By pivoting, the cam 9 of the lever 8 causes the shutter 27 to pass into the closed position in which it closes the filling tube 7.

La fermeture de l'obturateur 27 arrête l'écoulement de l'eau dans le tube de remplissage 7.Closing the shutter 27 stops the flow of water in the filling tube 7.

Apres la fermeture du robinet de remplissage, la position de l'ouverture 35, à proximité d'une partie inférieure de la paroi annulaire 6a, permet le vidage du réservoir 30, en l'absence d'écoulement d'un fluide dans le tube de remplissage 7.After closing the filling valve, the position of the opening 35, near a lower part of the annular wall 6a, allows the emptying of the reservoir 30, in the absence of a flow of fluid in the tube filling 7.

Ainsi, lors de la fermeture du robinet de commande 1, le réservoir 30 se vide dans le tube de remplissage 7 par l'orifice de vidage 41.Thus, when the control tap 1 is closed, the reservoir 30 empties into the filling tube 7 through the emptying orifice 41.

Le vidage du réservoir 30 permet l'ouverture de la prise d'air.The emptying of the reservoir 30 allows the opening of the air intake.

Le robinet de remplissage selon l'invention offre donc l'avantage d'utiliser un réservoir dont le remplissage, lors de l'ouverture du robinet de remplissage, permet d'obturer hydrauliquement la prise d'air. L'invention peut ainsi proposer un robinet de remplissage peu couteux qui permet d'éviter tout phénomène d'aspiration d'air extérieure lors du remplissage de la cuve de chasse.The filling valve according to the invention therefore offers the advantage of using a reservoir whose filling, when the filling valve is opened, makes it possible to hydraulically close the air intake. The invention can thus propose an inexpensive filling tap which makes it possible to avoid any phenomenon of suction of outside air when filling the flush tank.

En outre, le vidage du réservoir, lors de la fermeture du robinet de remplissage, permet l'ouverture de la prise d'air qui est conçue pour éviter tout phénomène de rétro-siphonage en cas de défaillance de l'obturateur conjuguée avec une dépression de la tubulure d'arrivée d'eau.In addition, the emptying of the tank, when the filling valve is closed, allows the opening of the air intake which is designed to avoid any back-siphoning phenomenon in the event of a shutter failure combined with a vacuum of the water inlet pipe.

Comme il va de soi, l'invention ne se limite pas à la seule forme d'exécution décrite ci-dessus à titre d'exemple. Elle embrasse au contraire toutes les variantes de réalisation.It goes without saying that the invention is not limited to the single embodiment described above by way of example. On the contrary, it embraces all the variant embodiments.
