Abstract

The device (10) has a transverse retractable abutment finger (62) interposed at right angles of a vertical blocking rod (22) to limit the rise of an element (16) in an intermediate open position of a water cistern (12) in which a float (18) is partly emerged by moving the element so as to open a valve element (15). The element is moved to a blocking position of the water cistern by a permanent magnet (28) to prevent the buoyancy effect being exerted on the float, so that the element closes the valve element to discharge a portion of the water from the water cistern to a lavatory pan. An independent claim is also included for a method for opening a flushing system of a lavatory.

Description

L'invention concerne un dispositif d'ouverture de chasse d'eau de toilettes.The invention relates to a toilet flushing opening device.

L'invention concerne plus particulièrement un dispositif d'ouverture de chasse d'eau de toilettes, qui comporte un réservoir d'eau alimenté par un robinet relié à un réseau de distribution d'eau, et qui est susceptible d'être ouvert pour provoquer le remplissage du réservoir lorsque le niveau d'eau descend en dessous d'une limite inférieure déterminée, et du type qui comporte un orifice d'évacuation inférieur et un clapet d'évacuation mobile vertical associé à cet orifice, qui est susceptible d'occuper une position basse fermée pour retenir l'eau à l'intérieur du réservoir ou une position haute ouverte pour évacuer l'eau vers une cuvette des toilettes, et du type qui comporte un élément, solidaire du clapet et comportant un flotteur, qui est susceptible de solliciter le clapet vers sa position ouverte sous l'effet de la poussée d'Archimède dès lors qu'au moins une fraction déterminée du flotteur est immergée, une face d'appui supérieure dudit élément étant susceptible d'être sélectivement bloquée ou débloquée par une extrémité inférieure libre d'une tige de blocage verticale, sensiblement coaxiale à l'élément, dont une extrémité supérieure libre comporte une plaque métallique, et qui est mobile verticalement entre :

  • une position de blocage, dans laquelle un aimant permanent solidaire du réservoir, agencé en regard de la plaque métallique de la tige, retient la plaque métallique sous l'influence de son champ magnétique permanent pour maintenir la tige bloquée au contact de la face d'appui supérieure de l'élément, afin d'immobiliser l'élément,
  • une position de déblocage, dans laquelle un premier solénoïde, agencé à proximité de l'aimant permanent, est commandé électriquement pour opposer un champ temporaire au champ magnétique crée par l'aimant permanent et libérer ainsi la plaque métallique de la tige afin de libérer l'élément, pour que ledit élément soit mobile entre :
  • une position inférieure de fermeture du réservoir plein, associée au blocage de l'élément par la tige à l'encontre de l'effet de la poussée d'Archimède s'exerçant sur flotteur, dans laquelle ledit élément ferme le clapet,
  • une position supérieure d'ouverture du réservoir, associée à la position de déblocage de l'élément par la tige, dans laquelle le flotteur, émergeant au maximum, sollicite l'élément pour ouvrir le clapet, la tige accompagnant l'élément selon une course maximale déterminée,
  • une position inférieure de fermeture du réservoir vide, préalable à un nouveau blocage de l'élément par la tige, dans laquelle ledit élément ferme le clapet.
The invention more particularly relates to a toilet flush opening device, which comprises a water tank fed by a valve connected to a water distribution network, and which can be opened to cause the filling of the reservoir when the water level falls below a determined lower limit, and of the type which comprises a lower discharge orifice and a vertical movable discharge valve associated with this orifice, which is likely to occupy a closed low position for retaining the water inside the tank or a high open position for discharging water to a toilet bowl, and of the type which comprises an element integral with the valve and comprising a float, which is capable of to urge the valve towards its open position under the effect of the buoyancy force as soon as at least a determined fraction of the float is immersed, an upper bearing surface of said element ant capable of being selectively blocked or unlocked by a free lower end of a vertical locking rod, substantially coaxial with the element, a free upper end of which comprises a metal plate, and which is vertically movable between:
  • a locking position, in which a permanent magnet secured to the reservoir, arranged facing the metal plate of the rod, holds the metal plate under the influence of its permanent magnetic field to keep the pin locked in contact with the face of upper support of the element, in order to immobilize the element,
  • an unlocking position, in which a first solenoid, arranged near the permanent magnet, is electrically controlled to oppose a temporary field to magnetic field created by the permanent magnet and thus release the metal plate of the rod to release the element, so that said element is movable between:
  • a lower position of closure of the full tank, associated with the blocking of the element by the rod against the effect of buoyancy force on float, in which said element closes the valve,
  • an upper tank opening position, associated with the unlocking position of the element by the rod, in which the float, emerging at the maximum, urges the element to open the valve, the rod accompanying the element in a race determined maximum,
  • a lower position of closing the empty tank, prior to a new blockage of the element by the rod, wherein said element closes the valve.

On connaît plusieurs dispositifs de chasse d'eau de toilettes dans lesquels un dispositif, qui utilise le principe de la poussée d'Archimède, permet de transmettre une poussée d'un flotteur immergé à un clapet d'ouverture du réservoir par l'intermédiaire d'un élément.Several toilet flushing devices are known in which a device, which uses the Archimedes thrust principle, makes it possible to transmit a thrust of a submerged float to a valve for opening the tank via a valve. 'an element.

Dans de tels dispositifs, le flotteur et l'élément sont généralement immobilisés par l'intermédiaire d'un mécanisme de verrouillage et lorsqu'ils sont libérés, ils sont susceptibles de transmettre leur mouvement de remontée au clapet pour provoquer l'ouverture dudit clapet.In such devices, the float and the element are generally immobilized by means of a locking mechanism and when they are released, they are able to transmit their upward movement to the valve to cause the opening of said valve.

Le mécanisme de verrouillage peut aisément être constitué d'un aimant permanent, coopérant avec une plaque métallique. Le champ magnétique généré par l'aiment permanent peut aisément être est annulé par un solénoïde ou électroaimant fonctionnant en basse tension et de façon autonome, afin de provoquer le déverrouillage de l'élément muni du flotteur et donc du clapet.The locking mechanism can easily be made of a permanent magnet cooperating with a metal plate. The magnetic field generated by the permanent magnet can easily be canceled by a solenoid or electromagnet operating at low voltage and autonomously, in order to cause the unlocking of the element provided with the float and therefore the valve.

Cette configuration permet notamment de proposer des chasses d'eau à commande automatique qui, lorsque l'utilisateur quitte les toilettes, déclenchent automatiquement l'actionnement de l'élément d'ouverture du réservoir afin de provoquer l'évacuation de l'eau en direction de la cuvette des toilettes.This configuration makes it possible, in particular, to provide automatically controlled flushing which, when the user leaves the toilet, automatically triggers the actuation of the tank opening element in order to cause the evacuation of the water towards the tank. from the toilet bowl.

Conventionnellement, la remontée de l'élément solidaire du clapet s'effectue jusqu'à ce que le flotteur émerge au maximum. La vidange du réservoir s'accomplit alors de manière intégrale jusqu'à ce que le flotteur, privé d'eau pour le soutenir, provoque la retombée du clapet sur son siège.Conventionally, the recovery of the integral element of the valve is carried out until the float emerges to the maximum. The emptying of the tank is then completed integrally until the float, deprived of water to support it, causes the fall of the valve on its seat.

On comprendra que cette conception provoque la vidange intégrale du réservoir, quand bien même seule une quantité d'eau réduite serait requise.It will be understood that this design causes complete emptying of the tank, even if only a reduced amount of water would be required.

L'invention remédie à cet inconvénient en proposant un perfectionnement d'un dispositif du type décrit ci-dessus permettant une vidange partielle du réservoir.The invention overcomes this disadvantage by proposing an improvement of a device of the type described above allowing partial emptying of the tank.

A cet effet, l'élément est bloqué dans une position déterminée de sa course de remontée et l'aimant permanent est dimensionné de manière à provoquer une attraction magnétique permettant la fermeture du clapet avant que l'eau ne se soit intégralement vidangée.For this purpose, the element is locked in a determined position of its upstroke and the permanent magnet is dimensioned so as to cause magnetic attraction to close the valve before the water is fully drained.

Dans ce but, l'invention propose un dispositif d'ouverture de chasse d'eau de toilettes du type précédemment décrit, caractérisé en ce qu'il comporte un doigt escamotable de butée transversale, qui est susceptible de s'interposer sélectivement au droit de la tige pour limiter la course de la tige à une partie déterminée de sa course maximale, afin de limiter la remontée de l'élément jusqu'à une position intermédiaire d'ouverture du réservoir dans laquelle le flotteur n'émerge qu'en partie en sollicitant l'élément pour ouvrir le clapet, et à partir de laquelle l'élément retourne à sa position de refermeture dès lors que les efforts conjugués du poids de l'élément et de la tige, sollicitée vers sa position de blocage par l'aimant permanent, surmontent l'effet de la poussée d'Archimède s'exerçant sur flotteur, pour n'évacuer qu'une partie de l'eau du réservoir vers la cuvette des toilettes.For this purpose, the invention proposes a toilet flushing opening device of the type previously described, characterized in that it comprises a retractable transverse stop finger, which may be selectively interposed with the right to the rod to limit the stroke of the rod to a determined portion of its maximum stroke, to limit the rise of the element to an intermediate position of opening of the tank in which the float emerges only partially in urging the element to open the valve, and from which the element returns to its closed position when the combined efforts of the weight of the element and the rod, biased to its locking position by the magnet permanent, overcome the effect of buoyancy on float, to evacuate only a portion of the water from the tank to the toilet bowl.

Dans la description qui va suivre, des éléments identiques ou ayant des fonctions similaires portent les mêmes chiffres de référence.In the following description, elements identical or having similar functions have the same reference numerals.

On a représenté sur les figures 1 à 3 l'ensemble d'un dispositif 10 d'ouverture de chasse d'eau de toilettes réalisé conformément à l'invention.We have shown on Figures 1 to 3 the assembly of a toilet flushing device 10 made in accordance with the invention.

De manière connue, comme l'illustrent plus particulièrement les figures 1 à 3, le dispositif 10 comporte un réservoir d'eau 12 qui est alimenté par un robinet (non représenté) qui est relié à un réseau de distribution d'eau.In a known manner, as is illustrated more particularly by Figures 1 to 3 , the device 10 comprises a water tank 12 which is fed by a tap (not shown) which is connected to a water distribution network.

De manière connue, comme l'illustre la figure 1, ce robinet est susceptible d'être ouvert pour provoquer le remplissage du réservoir 12 lorsque le niveau d'eau descend en dessous d'une limite inférieure "B" déterminée. Le robinet est destiné à se fermer automatiquement lorsque le niveau d'eau atteint une limite supérieure "A".In known manner, as illustrated by figure 1 , this valve is likely to be open to cause the filling of the tank 12 when the water level falls below a lower limit "B" determined. The faucet is meant to close automatically when the water level reaches an upper limit "A".

Le réservoir 12 comporte un orifice d'évacuation 14 inférieur et un clapet d'évacuation 15 mobile vertical qui est associé à cet orifice 14.The reservoir 12 comprises a lower discharge orifice 14 and a vertical movable discharge valve 15 which is associated with this orifice 14.

De manière connue, le clapet 15 est susceptible d'occuper une position basse fermée, qui a été représenté à la figure 1, pour retenir l'eau à l'intérieur du réservoir 12 ou une position haute ouverte, qui a été représentée à la figure 3, pour évacuer l'eau vers une cuvette (non représentée) des toilettes.In known manner, the valve 15 is likely to occupy a closed down position, which has been shown in FIG. figure 1 , to retain the water inside the tank 12 or a high open position, which has been shown in FIG. figure 3 , to evacuate the water to a bowl (not shown) of the toilet.

De manière connue, le dispositif 10 comporte un élément 16, solidaire du clapet 15 et comportant un flotteur 18, qui est susceptible de solliciter le clapet 15 vers sa position ouverte de la figure 3 sous l'effet bien connu de la poussée d'Archimède.In known manner, the device 10 comprises an element 16, integral with the valve 15 and having a float 18, which is able to urge the valve 15 to its open position of the figure 3 under the well-known effect of Archimedes' thrust.

Le flotteur 18 exerce donc un effort de levée de l'élément 16, causé par la Poussée d'Archimède, dès lors qu'au moins une fraction déterminée du flotteur 18 est immergée.The float 18 therefore exerts a lifting force of the element 16, caused by the buoyancy of Archimedes, since at least a determined fraction of the float 18 is immersed.

De manière connue, une face d'appui supérieure 26 dudit élément 16 est susceptible d'être sélectivement bloquée ou débloquée par une extrémité inférieure 20 libre d'une tige 22 de blocage verticale, sensiblement coaxiale à l'élément 16, dont une extrémité 24 supérieure libre comporte une plaque 34 métallique.In known manner, an upper bearing surface 26 of said member 16 is capable of being selectively locked or unlocked by a free lower end 20 of a vertical locking rod 22, substantially coaxial with the element 16, one end of which free upper includes a metal plate 34.

L'extrémité 24 supérieure de la tige 22 peut notamment être filetée et traverser la plaque métallique 34 à laquelle elle est fixée par un écrou.The upper end 24 of the rod 22 may in particular be threaded and pass through the metal plate 34 to which it is fixed by a nut.

Selon cette configuration, la tige 22 peut occuper une position de blocage, représentée à la figure 1, dans laquelle une face supérieure 32 d'un aimant 28 permanent solidaire du réservoir, agencée en regard de la plaque 34 métallique de la tige 22, retient la plaque métallique 34 sous l'influence de son champ magnétique permanent pour maintenir la tige 22 bloquée au contact de la face d'appui 26 supérieure de l'élément 16, afin d'immobiliser ledit élément 16.According to this configuration, the rod 22 can occupy a locking position, represented in FIG. figure 1 , wherein an upper face 32 of a permanent magnet 28 secured to the reservoir, arranged facing the metal plate 34 of the rod 22, holds the metal plate 34 under the influence of its permanent magnetic field to maintain the rod 22 blocked in contact with the upper bearing surface 26 of the element 16, in order to immobilize said element 16.

L'aimant permanent 28 forme ainsi une "ventouse magnétique" apte à retenir la tige 22.The permanent magnet 28 thus forms a "magnetic suction cup" capable of holding the rod 22.

Dans le mode de réalisation préféré de l'invention, et de manière non limitative de celle-ci, comme représenté aux figures 1 à 3, l'aimant permanent 28 est traversé par un tronçon vertical 30 de la tige 22. Il sera compris que le tronçon vertical 30 de la tige 22 peut occuper toute configuration à proximité de l'amant permanent sans être limité d'aucune façon par la configuration qui n'a ici été décrite qu'à titre d'exemple.In the preferred embodiment of the invention, and in a nonlimiting manner thereof, as shown in FIGS. Figures 1 to 3 the permanent magnet 28 is traversed by a vertical section 30 of the rod 22. It will be understood that the vertical section 30 of the rod 22 can occupy any configuration close to the permanent lover without being limited in any way by the configuration that has only been described here as an example.

La tige 22 peut aussi occuper une position de déblocage représentée aux figures 2 et 3, dans laquelle un premier solénoïde 38, agencé à proximité de l'aimant permanent 28, est commandé électriquement pour opposer un champ temporaire au champ magnétique crée par l'aimant 28 permanent et libérer ainsi la plaque métallique 34 de la tige qui est ainsi susceptible de quitter son contact avec la face supérieure 32 de l'aimant 28 permanent, libérant ainsi l'élément 16.The rod 22 can also occupy an unlocking position shown in FIGS. figures 2 and 3 , in which a first solenoid 38, arranged near the permanent magnet 28, is electrically controlled to oppose a temporary field to the magnetic field created by the permanent magnet 28 and thus release the metal plate 34 of the rod which is thus susceptible to leave its contact with the upper face 32 of the permanent magnet 28, thus releasing the element 16.

De la sorte, lorsque le solénoïde 38 est alimenté électriquement, le champ temporaire du solénoïde 38 s'oppose au champ permanent de l'aimant permanent 28. Ceci permet de libérer la plaque 34 métallique de la face supérieure 32 de l'aimant permanent 28.In this way, when the solenoid 38 is electrically powered, the temporary field of the solenoid 38 opposes the permanent field of the permanent magnet 28. This releases the metal plate 34 from the upper face 32 of the permanent magnet 28 .

La tige mobile 22 est mobile entre ces deux positions.The movable rod 22 is movable between these two positions.

Ces mouvements de la tige permettent donc à l'élément 16 d'être mobile entre différentes positions.These movements of the rod thus allow the element 16 to be mobile between different positions.

Comme l'illustre la figure 1, l'élément 16 peut occuper une position inférieure de fermeture du réservoir 12 plein, dans laquelle le niveau de l'eau contenue dans le réservoir correspond sensiblement à la ligne "A" de la figure 1.As illustrated by figure 1 , the element 16 can occupy a lower position for closing the tank 12 full, in which the level of the water contained in the reservoir corresponds substantially to the line "A" of the figure 1 .

Cette position est associée au blocage de l'élément 16 par la tige 22 à l'encontre de l'effet de la poussée d'Archimède s'exerçant sur le flotteur 18, et permet audit élément 16 de fermer le clapet 15.This position is associated with the locking of the element 16 by the rod 22 against the effect of the buoyancy force exerted on the float 18, and allows said element 16 to close the valve 15.

Comme l'illustre la figure 3, l'élément 16 peut occuper une position supérieure d'ouverture du réservoir 12, associée à la position de déblocage de l'élément 16 par la tige 22, dans laquelle le flotteur 22, émergeant au maximum, sollicite l'élément 16 pour ouvrir le clapet 15, la tige 22 accompagnant l'élément 16 selon une course maximale déterminée.As illustrated by figure 3 , the element 16 can occupy an upper opening position of the reservoir 12, associated with the unlocking position of the element 16 by the rod 22, in which the float 22, emerging as far as possible, urges the element 16 to open. the valve 15, the rod 22 accompanying the element 16 according to a determined maximum stroke.

A partir de cette position l'élément 16 accompagné par la tige 22 peut redescendre à mesure que le niveau de l'eau dans le réservoir descend du niveau représenté par la ligne "A" au niveau représenté par la ligne "B".From this position the element 16 accompanied by the rod 22 can go down as the level of the water in the tank goes down from the level represented by the line "A" at the level represented by the line "B".

Ainsi, comme l'illustre la figure 1, l'élément 16 peut alors occuper une position inférieure de fermeture du réservoir 12 vide, dans laquelle la niveau de l'eau contenue dans le réservoir correspond sensiblement à la ligne "B" de la figure 1.Thus, as illustrated by figure 1 the element 16 can then occupy a lower closing position of the empty tank 12, in which the level of the water contained in the reservoir corresponds substantially to the line "B" of the figure 1 .

Cette position correspond à un nouveau blocage de l'élément 16 par la tige 22 avant le remplissage du réservoir 12 et donc avant que l'effet de la poussée d'Archimède ne s'exerçe à nouveau sur le flotteur 18.This position corresponds to a new blocking of the element 16 by the rod 22 before the filling of the reservoir 12 and therefore before the effect of the buoyancy force is exerted again on the float 18.

Ainsi, dans son fonctionnement le plus simple, le dispositif 10 d'ouverture de chasse d'eau permet de manière connue de vidanger l'intégralité du contenu du réservoir 12 par le clapet 15.Thus, in its simplest operation, the flush opening device 10 makes it possible, in a known manner, to empty the entire contents of the tank 12 through the valve 15.

Il est néanmoins souhaitable de pouvoir proposer avec ce type de dispositif 10 une vidange partielle du réservoir 12, possibilité offerte par d'autres dispositifs connus de l'état de la technique ne fonctionnant pas selon le principe d'une ouverture du clapet par la Poussée d'Archimède.It is nevertheless desirable to be able to propose with this type of device 10 a partial emptying of the tank 12, possibility offered by other devices known from the state of the art not operating according to the principle of an opening of the valve by the thrust. Archimedes.

Or, on a constaté que, pour peu que d'une part l'aimant permanent 28 soit dimensionné de manière adéquate et puisse exercer un champ magnétique suffisamment puissant sur la plaque métallique 34, et que d'autre part le flotteur 18 n'émerge initialement pas en totalité, l'élément 16 pouvait occuper, comme l'illustre encore la figure 1, une position inférieure de refermeture du réservoir 12 au moins partiellement vidé, dans laquelle l'effet de la poussée d'Archimède s'exerçant sur flotteur 18 ne s'oppose pas suffisamment aux efforts conjugués du poids de l'élément 16 et de la tige 22, sollicitée vers sa position de blocage par l'aimant 28 permanent.However, it has been found that, provided that, on the one hand, the permanent magnet 28 is adequately sized and can exert a sufficiently strong magnetic field on the metal plate 34, and on the other hand the float 18 does not emerge. Initially not entirely, element 16 could occupy, as the figure 1 , a lower position of resealing the reservoir 12 at least partially emptied, wherein the effect of buoyancy thrust on float 18 does not sufficiently oppose the combined efforts of the weight of the element 16 and the rod 22, urged towards its locking position by the permanent magnet 28.

Dans ce cas la fermeture du clapet 15 peut donc se produire alors que le niveau de l'eau dans le réservoir 12 est intermédiaire entre les niveaux représentés par les lignes "A" et "B" et correspond par exemple au niveau "C".In this case the closure of the valve 15 may therefore occur while the water level in the reservoir 12 is intermediate between the levels represented by the lines "A" and "B" and corresponds for example to the level "C".

Cette propriété peut être mise à profit pour n'évacuer qu'une partie de l'eau du réservoir 12 vers la cuvette des toilettes.This property can be used to evacuate only a portion of the water tank 12 to the toilet bowl.

Pour mettre en application cette propriété, l'invention propose un dispositif 10 du type décrit précédemment, caractérisé en ce qu'il comporte un doigt 62 escamotable de butée transversale, qui est susceptible de s'interposer sélectivement au droit de la tige 22 pour limiter la course de la tige 22 à une partie déterminée de sa course maximale, afin de limiter la remontée de l'élément 16 jusqu'à une position intermédiaire d'ouverture du réservoir, représentée à la figure 2.To implement this property, the invention proposes a device 10 of the type described above, characterized in that it comprises a retractable finger 62 of transverse stop, which is capable of being selectively interposed with the right of the rod 22 to limit the stroke of the rod 22 at a determined part of its maximum stroke, in order to limit the rise of the element 16 to an intermediate position of opening of the reservoir, represented in FIG. figure 2 .

Dans cette position le flotteur 18 n'émerge qu'en partie en sollicitant l'élément 16 pour ouvrir le clapet 15, et par conséquent à partir de cette position l'élément 16 peut retourne vers une position inférieure de refermeture du réservoir au moins partiellement vidé, représentée à la figure 1, dans laquelle les efforts conjugués du poids de l'élément 16 et de la tige 22, sollicitée vers sa position de blocage par l'aimant permanent 28, surmontent l'effet de la poussée d'Archimède s'exerçant sur flotteur 18, pour que l'élément 16 ferme le clapet 15.In this position the float 18 emerges only partially by urging the element 16 to open the valve 15, and therefore from this position the element 16 can return to a lower position of reclosing the reservoir at least partially emptied, represented at figure 1 , in which the combined efforts of the weight of the element 16 and of the rod 22, biased towards its locking position by the permanent magnet 28, overcome the effect of the buoyancy force acting on the float 18, for that the element 16 closes the valve 15.

Il sera compris qu'au moment de la fermeture du clapet 15 il subsiste donc dans le réservoir une quantité d'eau correspondant au niveau illustré par la ligne "C". La vidange du réservoir 12 n'a donc été que partielle.It will be understood that at the time of closure of the valve 15 there is therefore in the tank a quantity of water corresponding to the level shown by the line "C". The emptying of the tank 12 was therefore only partial.

Plus particulièrement, le doigt escamotable 62 est mû par un second solénoïde 64, entre une position en retrait de la course la plaque métallique 34, comme représenté aux figures 1 et 3 et une position de butée, représentée à la figure 2, dans laquelle il s'étend au droit de la course de la plaque métallique 34 pour bloquer une face supérieure 66 de la plaque métallique 34.More particularly, the retractable finger 62 is moved by a second solenoid 64, between a position set back from the stroke of the metal plate 34, as shown in FIGS. figures 1 and 3 and an abutment position, shown in FIG. figure 2 in which it extends to the stroke of the metal plate 34 to block an upper face 66 of the metal plate 34.

De manière très simple, le doigt 62 peut être cylindrique et reçu dans un solénoïde de forme torique, mais cette configuration n'est évidemment pas limitative de l'invention.In a very simple way, the finger 62 can be cylindrical and received in a toroidal solenoid, but this configuration is obviously not limiting of the invention.

Dans le mode de réalisation préféré de l'invention, le dispositif 10 comporte un support 27, solidaire du réservoir 12 et présentant sensiblement une forme de "U", dont les branches 29 déterminent une concavité 31 dans laquelle sont reçus l'aimant 28 permanent et le premier solénoïde 38, de formes sensiblement cylindriques. La tige 22 traverse l'aimant 28 permanent, le premier solénoïde 38 et une branche horizontale 41 du support.In the preferred embodiment of the invention, the device 10 comprises a support 27, integral with the reservoir 12 and having substantially a "U" shape, whose branches 29 determine a concavity 31 in which the permanent magnet 28 is received. and the first solenoid 38, of substantially cylindrical shapes. The rod 22 passes through the permanent magnet 28, the first solenoid 38 and a horizontal arm 41 of the support.

Par ailleurs, l'élément 16 est sensiblement tubulaire et est coaxial au clapet 15. Une extrémité inférieure 55 de l'élément 16 comporte le clapet 15, et la tige 22 de blocage est elle aussi coaxiale à l'élément 16.Furthermore, the element 16 is substantially tubular and is coaxial with the valve 15. A lower end 55 of the element 16 comprises the valve 15, and the locking rod 22 is also coaxial with the element 16.

Cette configuration n'est aucunement limitative de l'invention, mais elle permet de limiter au maximum l'encombrement radial du dispositif 10.This configuration is in no way limitative of the invention, but it makes it possible to limit as much as possible the radial dimensions of the device 10.

Pour assurer le maintien de l'élément 16, de l'aimant permanent 28 et de la tige 22, le réservoir 12 comporte une cage 40 qui comporte une partie inférieure 42 tubulaire, dont une portée filetée 43 d'extrémité inférieure traverse un perçage 45 du réservoir 12 et est fixée sous une face inférieure 47 du réservoir au moyen d'un écrou 59. Cette configuration permet d'assurer la fixation de ladite partie inférieure 42 au réservoir 12.To ensure the maintenance of the element 16, the permanent magnet 28 and the rod 22, the reservoir 12 comprises a cage 40 which has a tubular lower portion 42, a threaded end 43 of which runs through a bore 45 of the reservoir 12 and is fixed under a lower face 47 of the reservoir by means of a nut 59. This configuration makes it possible to ensure the attachment of said lower portion 42 to the reservoir 12.

La partie inférieure 42 de la cage 40 comporte l'orifice 14 d'évacuation et l'élément 16 est monté coulissant à l'intérieur de la partie inférieure 42 pour sélectivement obturer ou découvrir l'orifice 14 d'évacuation.The lower portion 42 of the cage 40 includes the discharge orifice 14 and the element 16 is slidably mounted inside the lower portion 42 to selectively seal or discover the discharge orifice 14.

La cage 40 comporte aussi une partie supérieure 46 en forme de "U" inversé dont des bras supérieurs 48 sont fixés sur la partie inférieure 42. Les bras supérieurs 48 reçoivent le support 27 et comportent à leurs extrémités inférieures des crans 49 permettant leur réglage en hauteur dans des oeillets 51 de la partie inférieure 42.The cage 40 also has an inverted "U" shaped upper portion 46 whose upper arms 48 are fixed on the lower part 42. The upper arms 48 receive the support 27 and have at their lower ends notches 49 for their adjustment in height in eyelets 51 of the lower part 42.

Une partie supérieure 52 de l'élément tubulaire 16, qui fait saillie hors de la partie inférieure 42 tubulaire de la cage 40 entre les bras 48 de la partie supérieure 46 de la cage 40 reçoit le flotteur 18.An upper part 52 of the tubular element 16 protruding from the tubular lower part 42 of the cage 40 between the arms 48 of the upper part 46 of the cage 40 receives the float 18.

Avantageusement, le second solénoïde 64 est porté par un des bras 48 de la partie 46 supérieure de la cage 40.Advantageously, the second solenoid 64 is carried by one of the arms 48 of the upper portion 46 of the cage 40.

On remarquera que les bras 48 comportent chacun des lumières 25 destinées à recevoir des vis 23 de fixation du support 27 et une vis 70 de fixation du second solénoïde 64. Cette configuration permet de régler en hauteur le support 27 et surtout de régler en hauteur le solénoïde 64, ce qui permet de déterminer la quantité d'eau pouvant être vidangée partiellement.It will be noted that the arms 48 each comprise slots 25 intended to receive screws 23 for fixing the support 27 and a screw 70 for fixing the second solenoid 64. This configuration makes it possible to adjust the height of the support 27 and especially to adjust the height solenoid 64, which determines the amount of water that can be partially drained.

On remarquera que la partie supérieure 46 peut avantageusement comporter un filetage 57 pour la fixation d'accessoires électroniques (non représentés) et un filetage coaxial 39 pour la fixation d'un couvercle (non représenté) du réservoir.It will be noted that the upper portion 46 may advantageously comprise a thread 57 for the attachment of electronic accessories (not shown) and a coaxial thread 39 for fixing a cover (not shown) of the reservoir.

Par ailleurs, le flotteur 18 présente sensiblement la forme d'un "U" inversé dont la branche horizontale 17 traverse les bras supérieurs 48 de la partie supérieure 46 de la cage 40, et dont les bras latéraux 19 entourent la partie inférieure 42 de la cage 40. Le flotteur 18 est fixé au niveau de sa branche horizontale 17 sur la partie supérieure 52 de l'élément 16, notamment par emboîtement.Furthermore, the float 18 has substantially the shape of an inverted "U" whose horizontal branch 17 passes through the upper arms 48 of the upper portion 46 of the cage 40, and whose side arms 19 surround the lower portion 42 of the cage 40. The float 18 is fixed at its horizontal branch 17 on the upper part 52 of the element 16, in particular by interlocking.

Plus particulièrement, le flotteur 18 est réalisé en polystyrène expansé. Pour assurer la fixation du flotteur 18 et du clapet 16, la partie supérieure 52 en saillie de l'élément 16 comporte des dents 50 destinées à favoriser l'accrochage du flotteur 18 sur l'élément 16.More particularly, the float 18 is made of expanded polystyrene. To secure the float 18 and the valve 16, the upper portion 52 projecting from the element 16 has teeth 50 intended to promote the attachment of the float 18 on the element 16.

Avantageusement, l'élément 16 comporte la partie supérieure 52 tubulaire, à l'intérieur de laquelle est reçue au moins l'extrémité inférieure 20 de la tige 22,
L'élément 16 comporte aussi une partie inférieure 54 tubulaire, dont une extrémité inférieure reçoit le clapet 15 associé à l'orifice d'évacuation 14. Le clapet 15 est par exemple réalisé en matériau élastomère.Advantageously, the element 16 comprises the tubular upper part 52, within which is received at least the lower end 20 of the rod 22,
The element 16 also comprises a tubular lower portion 54, a lower end of which receives the valve 15 associated with the discharge orifice 14. The valve 15 is for example made of elastomeric material.

L'élément 16 comporte enfin une paroi interne transversale 58, délimitant la partie supérieure tubulaire 52 et la partie 54 inférieure tubulaire, qui est percée d'au moins un orifice 60 formant trop-plein. Cet orifice 60 est destiné à permettre le passage de l'eau dans l'élément 16 en direction d'un perçage 56 central du clapet 15. Ce perçage 56 est d'un diamètre inférieur à l'orifice d'évacuation 14 pour permettre l'évacuation de l'eau.The element 16 finally comprises a transverse inner wall 58 delimiting the tubular upper portion 52 and the tubular lower portion 54, which is pierced with at least one orifice 60 forming an overflow. This orifice 60 is intended to allow the passage of water in the element 16 in the direction of a central bore 56 of the valve 15. This bore 56 is of a smaller diameter than the discharge orifice 14 to allow evacuation of water.

Avantageusement, la paroi interne transversale 58 comporte la face d'appui 26 supérieure de l'élément 16 qui est destiné à recevoir la tige 22 en appui et l'orifice 60 est disposé radialement par rapport au point d'appui de la tige 22.Advantageously, the transverse inner wall 58 comprises the upper bearing face 26 of the element 16 which is intended to receive the rod 22 in abutment and the orifice 60 is arranged radially with respect to the fulcrum of the rod 22.

A cet effet, la tige 22 est d'une longueur adaptée.For this purpose, the rod 22 is of a suitable length.

La face d'appui 26 peut comporte plusieurs orifices 60, répartis angulairement de manière régulière autour de la tige 22.The bearing face 26 may comprise several orifices 60, angularly distributed regularly around the rod 22.

Si le robinet vient à se coincer en position ouverte, l'eau déborde par l'extrémité supérieure de la partie supérieure 52 de l'élément 16 et s'évacue par l'orifice 60 et le perçage 56 dans la cuvette des toilettes en évitant que le réservoir 12 ne déborde.If the tap becomes jammed in the open position, the water overflows through the upper end of the upper part 52 of the element 16 and is evacuated through the orifice 60 and the bore 56 in the toilet bowl avoiding that the reservoir 12 does not overflow.

Dans cette configuration, il sera compris qu'un procédé de commande d'un tel dispositif 10 peut comporter une étape d'évacuation de la totalité de l'eau du réservoir, au cours de laquelle on envoie une brève impulsion électrique dans le premier solénoïde 38 ce qui a pour effet de libérer temporairement la tige 22 et de permettre la remontée de l'élément 16 et du clapet 15 sous l'effet de la poussée d'Archimède appliquée au flotteur 18, jusqu'à ce que le flotteur 18 émerge au maximum, comme représenté à la figure 3.In this configuration, it will be understood that a method of controlling such a device 10 may comprise a step of evacuating all the water from the reservoir, during which a brief electrical impulse is sent into the first solenoid 38 which has the effect of temporarily releasing the rod 22 and allow the raising of the element 16 and the valve 15 under the effect of the buoyancy force applied to the float 18, until the float 18 emerges maximum, as shown in figure 3 .

Le procédé comporte une étape en variante d'évacuation d'une partie de l'eau du réservoir, au cours de laquelle on alimente le second solénoïde 64 puis on envoie une brève impulsion électrique dans le premier solénoïde 38 ce qui a pour effet de libérer temporairement la tige 22 et de ne permettre qu'une remontée partielle de l'élément 16 et du clapet 15 sous l'effet de la poussée d'Archimède appliquée au flotteur 18, jusqu'à la position de butée contre le doigt 62 comme représenté à la figure 2.The method comprises an alternative step of evacuating a portion of the water from the reservoir, during which the second solenoid 64 is fed, then a short electrical pulse is sent into the first solenoid 38, which has the effect of releasing temporarily the rod 22 and allow only a partial rise of the element 16 and the valve 15 under the effect of the buoyancy force applied to the float 18, to the abutment position against the finger 62 as shown to the figure 2 .

Dès lors, le clapet 15 étant ouvert, le niveau de l'eau diminue dans le réservoir 12 par conséquent l'effort exercé par la poussée d'Archimède sur le flotteur 18 diminue progressivement.Therefore, the valve 15 being open, the water level decreases in the tank 12 therefore the force exerted by the buoyancy force on the float 18 decreases gradually.

A un moment donné, l'attraction de l'aimant permanent 28, conjuguée au poids de l'élément 16, est supérieure à l'effort de exercé par la poussée d'Archimède sur le flotteur 18, ce qui entraîne la descente de l'élément 16 et la fermeture du clapet 15 avant que l'intégralité de l'eau ne se soit vidangée du réservoir.At a given moment, the attraction of the permanent magnet 28, combined with the weight of the element 16, is greater than the force exerted by the buoyancy force on the float 18, which causes the descent of the element 16 and closing the valve 15 before all the water has drained from the tank.

Une électronique de commande (non représentée), qui est fixée au filetage 57, par exemple peut être utilisée pour provoquer la libération de la tige 22 et/ou son blocage en envoyant une impulsion électrique au premier solénoïde 38 et en alimentant le second solénoïde 64. Des piles peuvent par exemple permettre l'alimentation d'une cascade de modules, comportant un module de détection électronique qui transmet une information, relative à la présence ou à l'absence d'une personne utilisatrice, à un module d'amplification, qui transmet cette information à une unité centrale qui détermine le temps de présence de la personne utilisatrice et, lorsque la présence de la personne utilisatrice n'est plus détectée au bout d'un certain temps, déclenche l'envoi d'une impulsion à un module de commande du solénoïde 38, qui fournit une impulsion électrique audit solénoïde 38 pour que celui-ci libère la tige 22 et provoque le vidange de la chasse d'eau.A control electronics (not shown), which is attached to the thread 57, for example, can be used to cause the release of the rod 22 and / or its blocking by sending an electrical pulse to the first solenoid 38 and feeding the second solenoid 64 For example, batteries can be used to power a cascade of modules. comprising an electronic detection module which transmits information relating to the presence or absence of a user to an amplification module, which transmits this information to a central unit which determines the time of presence of the person user, and when the presence of the user is no longer detected after a certain time, triggers the sending of a pulse to a control module of the solenoid 38, which provides an electrical pulse to said solenoid 38 so that it releases the rod 22 and causes the emptying of the flush.

Bien entendu, dans cette configuration, le dispositif est réglé sélectivement pour réaliser une vidange totale ou partielle du réservoir 12.Of course, in this configuration, the device is selectively adjusted to completely or partially empty the tank 12.

Comme on le voit, ce dispositif 10 d'ouverture de chasse d'eau est particulièrement avantageux car il permet de n'utiliser que des éléments alimentés sous une basse tension fournie par des piles, la poussée d'Archimède constituant la principale source d'énergie pour la totalité des efforts qui consomment beaucoup d'énergie.As can be seen, this flush opening device 10 is particularly advantageous because it makes it possible to use only elements supplied with a low voltage supplied by batteries, the buoyancy being the main source of energy. energy for all efforts that consume a lot of energy.
