Description

Chasse d'eau double flux  Double flow flush
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. Existing systems are not very reliable in operation, and in particular it often happens that the small volume issued "drifts" over time and becomes too weak, 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 flush toilets 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 flush dual flow of the kind mentioned above that 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 flush device with at least two flows is as defined in claim 1, improvements being defined in the subclaims.
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 planning to operate and control the dual flush via two timer valves, an initiator valve and a main valve, we obtain a particularly simple and reliable system.
De préférence, 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. Preferably, the actuating means comprise an opening or closing actuating valve, during a time interval which can take at least two values, a drain duct of the timing chamber of the control delay valve.
Suivant un mode de réalisation préféré, 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. According to a preferred embodiment, the actuating means comprise a rod, a pallet is interposed between the two control knobs and the rod and is rotatably mounted relative to a pivot point, the rotation of the pallet causing the displacement of the rod according to an actuating stroke, and adjusting means adjust the rotational stroke of the pallet under the effect of the small volume knob, so as to adjust the actuating stroke of the stem when the small button is actuated. volume, so to adjust the second delivered volume.
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 . Thus, according to the invention, it can be ensured, by modifying the setting, that the small volume delivered is kept at a suitable value, so that the operation in double flow remains effective during the life of the hunt.
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 de l'amorceur. Preferably, the adjustment means comprise a shim slidably mounted relative to the pallet and comprising a low end section, an intermediate inclined section and a high end section, the shim thus acting on the position of a stud coming from of the small volume knob, the pad being able, depending on the respective sliding of the shim relative to the pallet, to support either on the low, preferably horizontal, section of the shim, either on the inclined section, or on a slope, of the shim or on the upper end section, so that the block is more or less close to the small button volume, which regulates the race of the rod of the initiator.
A titre d'exemple, on décrit maintenant un mode de réalisation préféré de l'invention en se reportant aux dessins, dans lesquels : la figure 1 est une vue de face de la partie de commande d'un dispositif double chasse suivant l'invention, la palette étant dans une position de réglage dans laquelle le petit volume est en position moyenne ; la figure 2 est une vue en coupe du dispositif de la figure 1 en réglage maximum ; la figure 3 est une vue de face du dispositif des. By way of example, a preferred embodiment of the invention will now be described with reference to the drawings, in which: FIG. 1 is a front view of the control part of a dual flush device according to the invention the pallet being in a setting position in which the small volume is in the average position; Figure 2 is a sectional view of the device of Figure 1 in maximum setting; Figure 3 is a front view of the device.

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 flushing device according to the invention. Preferably, the hunt is embedded in a facade. A large volume knob 4 protrudes out of the facade and allows the user to select sending the large six-liter volume in the hunt. A button 5 of small volume also protrudes out of the facade and allows the user to select the sending of a small volume in the hunt, corresponding to a fraction of the large volume, for example three liters. Springs 6 and 7 are mounted together with the buttons to return the latter to the initial position after pushing 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 flush water are delivered by a flushing opening connected to a water supply duct. The flush opening is closed by a valve 20. The shutter more or less large opening by the valve is controlled by a valve 21 timing, said 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 delay chamber 22 whose volume varies as a function of the displacement of an upper plate 23 which delimits the timing chamber on the top. A spring is arranged to push up the upper plate 23.
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 upper position of the plate (maintained by the equal pressure of water on the part and else and by the action of the spring) the valve closes the flush opening, while in the lowered position of the plate, the flap does not close the flush opening and let 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 disposed inside the conduit 24 for supplying water between a water inlet opening 25 and the opening 26 flush 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 defines the chamber 22 of delay, but however not completely sealed. The duct water 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 delay chamber is filled with water, the duct being under the water pressure of 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 totally or partially emptying the timing chamber 22 of the valve 21 via a conduit 28 for emptying.
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 drained via the conduit 28 by a given amount, ie a large quantity in the case where it is desired that the valve 20 remains a long time out of its seat, for a large hunting volume. delivered, and a smaller amount in the case where it is desired that the valve 20 remains out of its seat for a shorter duration for a smaller delivered flush volume. This given amount is determined by the time during which the conduit is open. If a large amount of water is drained, 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 the flush delivers a large flush volume. If a smaller quantity 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 periphery of the plate is less, and so that the time during which the valve 20 is open is less, and therefore that the hunt delivers a smaller flush volume.
Cette vidange totale ou partielle de la chambre 22 de temporisation entraine 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 chamber 22 of delay 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 is set to not s opposing the descent of the plate in such a case) which then drives the valve 20 out of its seat and opens the opening 26 for hunting, 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. 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 delivery of the water is the time that the delay chamber 22 fills up again, gradually raising the plate 23, which gradually reduces the valve 20 in its seat, to the position in which the water pressures on both sides of the plate 23 equalize and that the valve closes the opening 26. The time that the chamber 22 of delay to fill after emptying defines the water flow of the hunt. In the case where the plate has descended a great height following the emptying (adjustable by the volume of water drained), the filling time is long and the flush volume delivered is large and in the case where the The plate has come down from a lower height (adjustable according to the volume of water drained), the filling time is shorter and the flush volume delivered is less, correspondingly.
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 delay chamber 22, and therefore the movement of the plate and the valve, the flushing control device further comprises a delay initiator valve 27 (which thus also comprises a delay chamber of actuation). The valve 27 is arranged to open a conduit 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. Entre les boutons petit volume et grand volume et la tige d' actionneur, 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. The initiator valve 27, or actuator, comprises a rod 8 whose displacement causes the opening of the conduit 29 for emptying the timing chamber of the initiator valve. This emptying of the delay chamber of the initiator 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 conduit 28 the time that the delay chamber of the faucet 27 fills up again. The drained volume of the delay chamber is proportional to the stroke of the stem 8, itself dependent on the button pressed between the small volume knob and the large volume knob. Between the small volume and large volume knobs and the actuator 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 button rod 4 of large volume and a stud 12 intended to come into contact with the small button knob 5 rod. 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 communicates for the fluids the timing chamber of the valve 27 with the outside as well as with the conduit 28 for discharging the water taken from the chamber 22 at the opening 26, simultaneously with the delivery of the large or small hunting 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 . Therefore, in fine, the flush volume delivered by the exit aperture 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 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. 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. When the user presses the large volume knob, as shown in FIG. 7, the button rod 4 presses on the stud 11, causing the pallet to rotate relative to its pivot point 10 and the pallet comes to press the rod 8 of the initiator valve. The corresponding stroke of the rod 8 causes the emptying of the delay chamber of the initiator valve, causing the opening of the conduit 28, then the emptying of the chamber 22 of delay and finally the delivery of the large flush volume the time that the chamber 22 fills again, after the closing of the duct 28 after refilling the timing chamber of the initiator valve. In the pallet, there is mounted a shim 13 of sliding adjustment relative to the pallet. It can thus move in translation in the direction to the right or to the left to the figures, that is to say, closer to or away from the pivot point 10 of the pallet. This adjustment shim 13 comprises a slope stop which acts on the position of the stud 12, depending on its position. In the position shown in Figure 3, the stud 12 rests on the lower horizontal portion of the shim. In the middle position, shown in Figure 5, the stud 12 comes into contact with the inclined portion or slope of the wedge. Finally, in the maximum position, represented in FIG. 1, the stud 12 comes into contact with the wedge in the upper adjustment part. Thus, depending on the respective position of the shim and pad 12, the latter is more or less close to the small volume knob 5. The closer it is (maximum position), the more the pushing action of the button 5 on the pallet will cause a large stroke in rotation of the pallet relative to its pivot point and the greater the stroke of the rod of the actuator under the effect of the thrust of the pallet. On the contrary, the further the stud will be away from the button 5, the less the stroke achieved by the rotation of the pallet during the action by the button 5 and less will be the translation of the actuator rod of the initiator. Thus, the stroke of the rod of the actuator is proportional to the drained volume of the delay chamber of the initiator valve 17 and therefore to the time during which the conduit 18 empties the timing chamber 22 and therefore to the time during which the valve 20 is out of his seat and leave the opening 26 open. The time during which the opening 26 is open likewise determines the volume of hunting 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, it is possible to adjust the volume of the small hunt with precision, simply by sliding the wedge relative to the pallet. In particular, it is possible to provide, as shown in the figures in side views, indications and also notches to easily adjust the translational sliding of the shim.
