Description

La présente invention se rapporte à une chasse d'eau double flux comportant au moins deux boutons de commande pour commander respectivement la délivrance d'un premier grand volume ou d'un deuxième volume plus petit. Les systèmes existants ne sont pas très fiables en fonctionnement, et notamment il arrive souvent que le petit volume délivré "dérive" au cours du temps et devienne trop faible, de sorte que cette fonctionnalité devient inopérante.The present invention relates to a dual-flow flush comprising at least two control buttons for respectively controlling the delivery of a first large volume or a second smaller volume. The existing systems are not very reliable in operation, and in particular it often happens that the small volume delivered "drifts" over time and becomes too low, so that this functionality becomes inoperative.

On connaît déjà des chasses d'eau double flux de l'art antérieur, notamment dans US 2011/0155934 . Cependant, ces chasses d'eau comportent un actionnement hydraulique et sont coûteuses et compliquées à fabriquer et sont peu fiables.Double-flow flushes of the prior art are already known, in particular in US 2011/0155934 . However, these flushes have hydraulic actuation and are expensive and complicated to manufacture and are unreliable.

On aimerait avoir à disposition une chasse d'eau double flux du genre mentionné ci-dessus qui soit plus simple à fabriquer et plus fiable en fonctionnement au cours du temps.We would like to have available a double-flow flush of the type mentioned above which is simpler to manufacture and more reliable in operation over time.

Suivant l'invention, le dispositif de chasse d'eau à au moins deux flux est tel que défini à la revendication 1, des perfectionnements étant définis dans les sous-revendications.According to the invention, the at least two-stream flushing device is as defined in claim 1, improvements being defined in the sub-claims.

En prévoyant ainsi d'actionner et de commander la double chasse par l'intermédiaire de deux robinets temporisateurs, un robinet amorceur et un robinet principal, on obtient un système particulièrement simple et fiable.By thus providing to actuate and control the double flush through two timer taps, a priming tap and a main tap, we obtain a particularly simple and reliable system.

Selon la présente invention, les moyens d'actionnement comportent un robinet temporisateur d'actionnement ouvrant ou fermant, pendant un intervalle de temps pouvant prendre au moins deux valeurs, un conduit de vidange de la chambre de temporisation du robinet de temporisation de commande.According to the present invention, the actuation means comprise an actuation timer valve which opens or closes, during a time interval which may take at least two values, a duct for emptying the timing chamber of the control timing valve.

Selon la présente invention, les moyens d'actionnement comportent une tige, une palette est intercalée entre les deux boutons de commande et la tige et est montée rotative par rapport à un point pivot, la rotation de la palette entraînant le déplacement de la tige suivant une course d'actionnement, et des moyens de réglage règlent la course en rotation de la palette sous l'effet du bouton petit volume, de manière à régler la course d'actionnement de la tige lors de la commande par le bouton petit volume, pour ainsi régler le deuxième volume délivré. Ainsi, suivant l'invention on peut s'assurer, en modifiant le réglage, que le petit volume délivré est maintenu à une valeur appropriée, de sorte que le fonctionnement en double flux reste effectif au cours de la durée de vie de la chasse.According to the present invention, the actuating means comprise a rod, a pallet is interposed between the two control buttons and the rod and is rotatably mounted with respect to a pivot point, the rotation of the pallet causing the displacement of the following rod an actuation stroke, and adjustment means adjust the rotational stroke of the pallet under the effect of the low volume button, so as to adjust the actuation stroke of the rod when the control is carried out by the low volume button, to thus adjust the second delivered volume. Thus, according to the invention it is possible to ensure, by modifying the setting, that the small volume delivered is maintained at an appropriate value, so that the double-flow operation remains effective during the life of the flush.

De préférence, les moyens de réglage comportent une cale montée coulissante par rapport à la palette et comportant un tronçon d'extrémité bas, un tronçon incliné intermédiaire et un tronçon d'extrémité haut, la cale agissant ainsi sur la position d'un plot issu du bouton petit volume, le plot pouvant, en fonction du coulissement respectif de la cale par rapport à la palette, appuyer soit sur le tronçon bas, de préférence horizontal, de la cale, soit sur le tronçon incliné, ou en pente, de la cale soit sur le tronçon d'extrémité haute, de sorte que le plot se trouve plus ou moins proche du bouton de petit volume, ce qui règle la course de la tige d'actionnement.Preferably, the adjustment means comprise a wedge mounted to slide relative to the pallet and comprising a bottom end section, an intermediate inclined section and a top end section, the wedge thus acting on the position of a stud resulting from the small volume button, the stud being able, depending on the respective sliding of the wedge with respect to the pallet, to press either on the low section, preferably horizontal, of the wedge, either on the inclined or sloping section of the wedge or on the high end section, so that the stud is more or less close to the small button volume, which adjusts the stroke of the actuating rod.

Aux figures, il est représenté un dispositif formant chasse à double flux suivant l'invention. De préférence, la chasse est encastrée dans une façade. Un bouton 4 de grand volume fait saillie hors de la façade et permet à l'utilisateur de sélectionner l'envoi du grand volume de six litres dans la chasse. Un bouton 5 de petit volume fait également saillie hors de la façade et permet à l'utilisateur de sélectionner l'envoi d'un petit volume dans la chasse, correspondant à une fraction du grand volume, par exemple trois litres. Des ressorts 6 et 7 sont montés en collaboration avec les boutons pour ramener ces derniers en position initiale après poussée par l'utilisateur.In the figures, there is shown a dual-flow flushing device according to the invention. Preferably, the hunt is embedded in a facade. A large volume button 4 protrudes out of the faceplate and allows the user to select the sending of the large volume of six liters into the flush. A button 5 of small volume also protrudes out of the faceplate and allows the user to select the sending of a small volume in the flush, corresponding to a fraction of the large volume, for example three liters. Springs 6 and 7 are mounted in conjunction with the buttons to return the latter to the initial position after being pushed by the user.

Les volumes (petit ou grand) d'eau de la chasse sont délivrés par une ouverture de chasse connectée à un conduit d'amenée d'eau. L'ouverture de chasse est obturée par un clapet 20. L'obturation plus ou moins grande de l'ouverture par le clapet est commandée par un robinet 21 de temporisation, dit de commande.The volumes (small or large) of flushing water are delivered by a flush opening connected to a water supply pipe. The flushing opening is closed by a valve 20. The more or less closing of the opening by the valve is controlled by a delay valve 21, called control.

Le robinet 21 de temporisation de commande comporte une chambre de temporisation 22 de commande dont le volume varie en fonction du déplacement d'une plaque 23 supérieure qui délimite la chambre de temporisation sur le dessus. Un ressort est disposé de manière à repousser vers le haut la plaque 23 supérieure.The control timing valve 21 comprises a control timing chamber 22, the volume of which varies as a function of the displacement of an upper plate 23 which delimits the timing chamber on the top. A spring is arranged so as to push the upper plate 23 upwards.

La plaque 23 est reliée au clapet 20 pour coopérer avec ce dernier, de sorte qu'en position haute de la plaque (maintenue par l'égalité des pressions d'eau de part et d'autre et par l'action du ressort) le clapet obture l'ouverture de chasse, tandis qu'en position abaissée de la plaque, le clapet n'obture pas l'ouverture de chasse et laisse un flux d'eau se déverser.The plate 23 is connected to the valve 20 to cooperate with the latter, so that in the high position of the plate (maintained by the equality of the water pressures on both sides. other and by the action of the spring) the valve closes the flushing opening, while in the lowered position of the plate, the valve does not block the flushing opening and lets a flow of water flow .

Le robinet 21 de temporisation est disposé à l'intérieur du conduit 24 d'amenée d'eau entre une ouverture 25 d'arrivée d'eau et l'ouverture 26 de chasse obturée par le clapet.The timing valve 21 is placed inside the water supply duct 24 between a water inlet opening 25 and the flushing opening 26 closed by the valve.

La plaque 23 délimite la chambre 22 de temporisation, mais cependant pas de manière totalement étanche. L'eau du conduit peut passer dans la chambre 22 au niveau du bord périphérique de la plaque 23.The plate 23 delimits the delay chamber 22, but not however completely sealed. The water from the duct can pass into the chamber 22 at the peripheral edge of the plate 23.

Dans la position normale (c'est-à-dire pendant laquelle la chasse ne délivre pas d'eau), l'ouverture 26 est obturée par le clapet 20 et la chambre de temporisation est remplie d'eau, le conduit étant sous la pression d'eau du réseau d'alimentation et la pression de l'eau étant la même au-dessus et en dessous de la plaque, qui se trouve donc en position haute.In the normal position (that is to say during which the flush does not deliver water), the opening 26 is closed by the valve 20 and the timing chamber is filled with water, the duct being under the water pressure from the supply network and the water pressure being the same above and below the plate, which is therefore in the high position.

On commande le déplacement de la plaque 23 en vidant totalement ou en partie la chambre 22 de temporisation du robinet 21 par l'intermédiaire d'un conduit 28 de vidange.The movement of the plate 23 is controlled by completely or partially emptying the timing chamber 22 of the valve 21 via a drain pipe 28.

La chambre 22 de temporisation est vidangée par l'intermédiaire du conduit 28 d'une quantité donnée, à savoir une grande quantité dans le cas où l'on souhaite que le clapet 20 reste longtemps hors de son siège, pour un grand volume de chasse délivré, et une moindre quantité dans le cas où l'on souhaite que le clapet 20 reste hors de son siège pendant une durée moins longue pour un volume de chasse délivré plus petit. Cette quantité donnée est déterminée par le temps pendant lequel le conduit est ouvert. Si on vidange une grande quantité d'eau, on fait en sorte que le temps mis par la plaque 23 pour remonter sous l'effet de l'eau qui s'infiltre dans la chambre de temporisation au niveau de la périphérie de la plaque soit grand et donc que le temps pendant lequel le clapet 20 est ouvert soit grand, et donc que la chasse délivre un grand volume de chasse. Si on vidange une quantité moindre, on fait en sorte que le temps mis par la plaque 23 pour remonter sous l'effet de l'eau qui s'infiltre dans la chambre de temporisation au niveau de la périphérie de la plaque soit moindre, et donc que le temps pendant lequel le clapet 20 est ouvert soit moindre, et donc que la chasse délivre un plus petit volume de chasse.The delay chamber 22 is emptied through the conduit 28 of a given quantity, namely a large quantity in the case where it is desired that the valve 20 remains out of its seat for a long time, for a large flushing volume. delivered, and a smaller amount in the event that it is desired that the valve 20 remains out of its seat for a shorter duration for a smaller volume of hunting delivered. This given amount is determined by the time the duct is open. If a large quantity of water is emptied, it is ensured that the time taken by the plate 23 to rise under the effect of the water which infiltrates into the delay chamber at the level of the periphery of the plate is large and therefore that the time during which the valve 20 is open is large, and therefore that the flush delivers a large volume of flush. If a smaller quantity is emptied, the time taken for the plate 23 to rise under the effect of the water which infiltrates the delay chamber at the periphery of the plate is made to be less, and therefore that the time during which the valve 20 is open is less, and therefore that the flush delivers a smaller flush volume.

Cette vidange totale ou partielle de la chambre 22 de temporisation entraîne la descente de la plaque 23 (puisque la pression de l'eau au dessus devient plus grande que la pression à l'intérieur de la chambre et le ressort étant réglé pour ne pas s'opposer à la descente de la plaque dans un tel cas) qui entraîne alors le clapet 20 hors de son siège et ouvre l'ouverture 26 de chasse, permettant la délivrance d'un volume d'eau.This total or partial emptying of the delay chamber 22 causes the descent of the plate 23 (since the pressure of the water above becomes greater than the pressure inside the chamber and the spring being adjusted so as not to s 'oppose the descent of the plate in such a case) which then drives the valve 20 out of its seat and opens the flushing opening 26, allowing the delivery of a volume of water.

La délivrance de l'eau se fait le temps que la chambre de temporisation 22 se remplisse de nouveau, faisant remonter petit à petit la plaque 23, ce qui ramène petit à petit le clapet 20 dans son siège, jusque dans la position dans laquelle les pressions de l'eau des deux côtés de la plaque 23 s'égalisent et que le clapet obture l'ouverture 26.The water is delivered while the timing chamber 22 fills up again, gradually raising the plate 23, which gradually returns the valve 20 in its seat, to the position in which the water pressures on both sides of the plate 23 equalize and the valve closes the opening 26.

Le temps que met la chambre 22 de temporisation pour se remplir après sa vidange définit le débit d'eau de la chasse. Dans le cas où la plaque est descendue d'une grande hauteur à la suite de la vidange (réglable par le volume d'eau vidangé), le temps de remplissage est long et le volume de chasse délivré est grand et dans le cas ou la plaque est descendue d'une moindre hauteur (réglable en fonction du volume d'eau vidangé), le temps de remplissage est moindre et le volume de chasse délivré est moindre, de manière correspondante.The time taken by the delay chamber 22 to fill up after it has been emptied defines the flow rate of the flushing water. In the event that the plate is lowered from a great height following the emptying (adjustable by the volume of water emptied), the filling time is long and the flushing volume delivered is large and in the case where the The plate is lowered from a lower height (adjustable according to the volume of water drained), the filling time is less and the flushing volume delivered is correspondingly lower.

Pour commander ou actionner la vidange de la chambre 22 de temporisation, et donc le déplacement de la plaque et du clapet, le dispositif de commande de chasse comporte en outre un robinet amorceur 27 de temporisation (qui comporte donc également une chambre de temporisation d'actionnement). Le robinet 27 est agencé de manière à ouvrir un conduit 28 de vidange de la chambre 22 de temporisation de commande et à le fermer.To control or actuate the emptying of the timing chamber 22, and therefore the movement of the plate and the valve, the flushing control device further comprises a timing initiator valve 27 (which therefore also comprises a timing chamber of actuation). The valve 27 is arranged so as to open a duct 28 for emptying the control delay chamber 22 and to close it.

Le robinet 27 amorceur, ou actionneur, comporte une tige 8 dont le déplacement entraîne l'ouverture du conduit 29 de vidange de la chambre de temporisation du robinet amorceur. Cette vidange de la chambre de temporisation du robinet amorceur entraîne, suivant un principe identique à celui décrit pour la coopération entre la plaque 23 et le clapet 20, l'ouverture d'un clapet du conduit 28 le temps que la chambre de temporisation du robinet 27 se remplisse de nouveau. Le volume vidangé de la chambre de temporisation est proportionnel à la course de la tige 8, elle-même dépendante du bouton pressé entre le bouton petit volume et le bouton grand volume.The initiator valve 27, or actuator, comprises a rod 8 whose movement causes the opening of the drain pipe 29 of the timing chamber of the initiator valve. This emptying of the timing chamber of the priming valve causes, according to a principle identical to that described for the cooperation between the plate 23 and the valve 20, the opening of a valve of the duct 28 while the timing chamber of the valve 27 fills up again. The volume drained from the timing chamber is proportional to the stroke of the rod 8, itself dependent on the button pressed between the low volume button and the high volume button.

Entre les boutons petit volume et grand volume et la tige d'actionnement, il est monté une palette 9. La palette est montée rotative par rapport à un point pivot d'extrémité 10. La palette comporte un plot 11 destiné à venir en contact avec la tige du bouton 4 de grand volume et un plot 12 destiné à venir en contact avec la tige du bouton 5 de petit volume. Le plot 11 est plus proche du point pivot que le plot 12.Between the small volume and large volume buttons and the actuating rod, there is mounted a pallet 9. The pallet is rotatably mounted relative to an end pivot point 10. The pallet comprises a stud 11 intended to come into contact with the rod of the button 4 of large volume and a stud 12 intended to come into contact with the rod of the button 5 of small volume. The stud 11 is closer to the pivot point than the stud 12.

Un conduit 29 dans le robinet amorceur 27 met en communication pour les fluides la chambre de temporisation du robinet 27 avec l'extérieur ainsi qu'avec le conduit 28 pour décharger l'eau prélevée dans la chambre 22 au niveau de l'ouverture 26, simultanément à la délivrance du volume de chasse grand ou petit par l'ouverture 26.A conduit 29 in the initiator valve 27 places the timing chamber of the valve 27 in communication with the outside as well as with the conduit 28 for the fluids to discharge the water taken from the chamber 22 at the level of the opening 26, simultaneously with the delivery of the large or small flush volume through the opening 26.

Par conséquent, in fine, le volume de chasse délivré par l'ouverture de sortie est fonction de la course de la tige 8 d'actionnement.Consequently, ultimately, the flush volume delivered by the outlet opening is a function of the stroke of the actuating rod 8.

Lorsque l'utilisateur appuie sur le bouton de grand volume, comme représenté à la figure 7, la tige du bouton 4 vient appuyer sur le plot 11, entraînant en rotation la palette par rapport à son point pivot 10 et la palette vient presser la tige 8 d'actionnement du robinet amorceur. La course correspondante de la tige 8 entraîne la vidange de la chambre de temporisation du robinet amorceur, entraînant l'ouverture du conduit 28, puis la vidange de la chambre 22 de temporisation et enfin la délivrance du grand volume de chasse le temps que la chambre 22 se remplisse de nouveau, après la fermeture du conduit 28 consécutive au remplissage de nouveau de la chambre de temporisation du robinet amorceur.When the user presses the high volume button, as shown in figure 7 , the rod of the button 4 comes to press on the stud 11, causing the pallet to rotate relative to its pivot point 10 and the pallet presses the rod 8 for actuating the priming valve. The corresponding stroke of the rod 8 causes the emptying of the timing chamber of the priming valve, causing the opening of the conduit 28, then the emptying of the timing chamber 22 and finally the delivery of the large flushing volume while the chamber 22 fills again, after the closure of the conduit 28 following the refilling of the timing chamber of the initiator valve.

Dans la palette, il est monté une cale 13 de réglage coulissante par rapport à la palette. On peut ainsi la déplacer en translation dans la direction vers la droite ou vers la gauche aux figures, c'est-à-dire la rapprocher ou l'éloigner du point pivot 10 de la palette. Cette cale 13 de réglage comporte une butée en pente qui agit sur la position du plot 12, en fonction de sa position. Dans la position représentée à la figure 3, le plot 12 appuie sur la partie basse horizontale de la cale. Dans la position médiane, représentée à la figure 5, le plot 12 vient en contact avec la partie inclinée ou en pente de la cale. Enfin, dans la position maximum, représentée à la figure 1, le plot 12 vient en contact avec la cale en partie haute de réglage. Ainsi, en fonction de la position respective de la cale de réglage et du plot 12, ce dernier se trouve plus ou moins proche du bouton 5 de petit volume. Plus il est proche (position dite au maximum), plus l'action de poussée du bouton 5 sur la palette va entraîner une course importante en rotation de la palette par rapport à son point pivot et plus sera grande la course de la tige de l'actionneur sous l'effet de la poussée de la palette. Au contraire, plus le plot sera éloigné du bouton 5, moins sera grande la course réalisée par la rotation de la palette lors de l'action par le bouton 5 et moindre sera la translation de la tige d'actionnement de l'amorceur. Ainsi, la course de la tige de l'actionneur est proportionnelle au volume vidangé de la chambre de temporisation du robinet amorceur 17 et donc au temps pendant lequel le conduit 18 vidange la chambre 22 de temporisation et donc au temps pendant lequel le clapet 20 est sorti de son siège et laisse l'ouverture 26 ouverte. Le temps pendant lequel l'ouverture 26 est ouverte détermine de même le volume de chasse délivré.In the pallet, there is mounted a wedge 13 for sliding adjustment relative to the pallet. It is thus possible to move it in translation in the direction to the right or to the left in the figures, that is to say to bring it closer to or away from the pivot point 10 of the pallet. This adjustment wedge 13 comprises a slope stop which acts on the position of the stud 12, as a function of its position. In the position shown in figure 3 , the stud 12 presses on the lower horizontal part of the wedge. In the middle position, shown in figure 5 , the stud 12 comes into contact with the inclined or sloping part of the wedge. Finally, in the maximum position, shown in figure 1 , the stud 12 comes into contact with the wedge in the upper adjustment part. Thus, depending on the respective position of the adjustment wedge and of the stud 12, the latter is more or less close to the button 5 of small volume. The closer it is (so-called maximum position), the more the pushing action of button 5 on the pallet will cause a significant rotational travel of the pallet relative to its pivot point and the greater the travel of the rod of the actuator under the effect of the thrust of the pallet. On the contrary, the farther away the stud is from the button 5, the less will be the stroke achieved by the rotation of the pallet during the action by the button 5 and the less will be the translation of the actuating rod of the initiator. Thus, the stroke of the actuator rod is proportional to the volume emptied of the timing chamber of the priming valve 17 and therefore to the time during which the duct 18 empties the timing chamber 22 and therefore to the time during which the valve 20 is out of his seat and leaves the opening 26 open. The time during which the opening 26 is open also determines the volume of hunt issued.

Ainsi, suivant le système représenté, on peut régler le volume de la petite chasse avec précision, par simple coulissement de la cale par rapport à la palette. Notamment, on peut prévoir, comme représenté aux figures en vues de côté, des indications et également des crantages pour régler facilement le coulissement en translation de la cale de réglage.Thus, according to the system shown, the volume of the small flush can be adjusted with precision, simply by sliding the wedge relative to the pallet. In particular, there can be provided, as shown in the figures in side views, indications and also notches to easily adjust the sliding in translation of the adjustment wedge.
