Description

La présente invention concerne un dispositif de toilettes et plus particulièrement un dispositif de vidange de réservoir de chasse.The present invention relates to a toilet device and more particularly to a flush tank emptying device.

Les dispositifs de toilettes majoritairement répandus, utilisent la gravité pour vider le réservoir de chasse. Ainsi, le mécanisme traditionnellement utilisé comporte un réservoir placé en hauteur, relié à une cuvette. Le réservoir est fermé par un obturateur mobile dans sa partie inférieure. Lorsque l'utilisateur actionne le mécanisme de chasse, l'obturateur est retiré et le liquide tombe dans la cuvette. Puis, alors que le réservoir achève de se vider, l'obturateur vient obturer l'orifice du réservoir afin d'arrêter l'écoulement du liquide. Des exemples de telles toilettes peuvent être trouvés dans les documents FR 1188762 , EP 2045406 et FR 972728 .Most common toilet devices use gravity to empty the flush tank. Thus, the mechanism traditionally used comprises a reservoir placed in height, connected to a bowl. The tank is closed by a movable shutter in its lower part. When the user activates the flushing mechanism, the shutter is removed and the liquid falls into the bowl. Then, while the reservoir is finishing emptying, the shutter closes off the orifice of the reservoir in order to stop the flow of the liquid. Examples of such toilets can be found in the documents EN 1188762 , EP 2045406 and FR 972728 .

Ainsi, ce système oblige le positionnement en hauteur du réservoir de chasse, ce qui ne permet pas la fabrication de systèmes compacts.Thus, this system requires the height positioning of the cistern, which does not allow the manufacture of compact systems.

De plus, l'usure du mécanisme de déplacement du bouchon et l'usure du bouchon lui-même peuvent être la cause de fuites d'eau dans la cuvette.In addition, wear of the stopper moving mechanism and wear of the stopper itself can be the cause of water leaks into the bowl.

Dans ce contexte technique, un but de la présente invention est de proposer un dispositif de toilettes compactes qui, de plus, ne soit pas sujet aux problèmes de fuites qui se posent dans les dispositifs connus.In this technical context, an object of the present invention is to provide a compact toilet device which, moreover, is not subject to the problems of leaks which arise in known devices.

Selon une définition générale, l'invention concerne un dispositif de toilettes conforme à la revendication 1.According to a general definition, the invention relates to a toilet device according to claim 1.

Ainsi, le dispositif de toilettes selon l'invention utilise l'aspiration générée par l'effet Venturi pour vider le réservoir de chasse dans la cuvette.Thus, the toilet device according to the invention uses the suction generated by the Venturi effect to empty the flush tank into the bowl.

L'invention permet ainsi de proposer un dispositif de toilettes compactes, dont l'architecture s'affranchit de l'utilisation de la gravité. De plus le dispositif selon l'invention évite les fuites inhérentes aux dispositifs de l'art antérieur, car il ne comporte pas d'obturateur.The invention thus makes it possible to propose a compact toilet device, the architecture of which does away with the use of gravity. In addition, the device according to the invention avoids the leaks inherent in the devices of the prior art, since it does not include a shutter.

Selon un mode réalisation, le flotteur grande chasse peut maintenu par un aimant lié à l'actionneur manuel de déclenchement commandant l'arrivée d'eau pressurisée dans les moyens d'éjection.According to one embodiment, the large flush float can be held by a magnet linked to the manual trigger actuator controlling the pressurized water supply to the ejection means.

Ainsi, l'invention utilise avantageusement la force exercée par le liquide contenu dans le réservoir de chasse sur le flotteur grande chasse, pour commander l'arrivée d'eau pressurisée dans les moyens d'éjection.Thus, the invention advantageously uses the force exerted by the liquid contained in the cistern on the big flush float, to control the arrival of pressurized water in the ejection means.

En outre, l'utilisation d'un aimant lié à l'actionneur manuel de déclenchement permet à l'invention de présenter des éléments de commande peu sensibles à l'usure et résistants à l'humidité.Furthermore, the use of a magnet linked to the manual tripping actuator enables the invention to present control elements which are not very sensitive to wear and which are resistant to humidity.

De plus, la tige peut présenter une rondelle qui permet au flotteur grande chasse d'exercer une pression sur la tige pour commander l'arrivée d'eau pressurisée dans les moyens d'éjection.In addition, the stem may have a washer which allows the big flush float to exert pressure on the stem to control the pressurized water supply to the ejection means.

Ainsi le flotteur grande chasse peut coulisser sur la tige entre une position dans laquelle le flotteur est aimanté à l'aimant, et une position dans laquelle le flotteur est en butée contre la rondelle et exerce une pression sur la tige.Thus the big flush float can slide on the rod between a position in which the float is magnetized to the magnet, and a position in which the float is in abutment against the washer and exerts pressure on the rod.

Selon un autre mode de réalisation, le flotteur petite chasse peut être fixé à la tige qui commande l'arrivée d'eau pressurisée dans les moyens d'éjection.According to another embodiment, the small flush float can be fixed to the rod which controls the pressurized water supply to the ejection means.

Avantageusement il est possible de combiner plusieurs flotteurs liés à la tige suivant différents mode de réalisation, pour obtenir des commandes différentes de l'arrivée d'eau pressurisée dans les moyens d'éjection. Il est ainsi possible de combiner plusieurs flotteurs pour obtenir des volumes différents de liquide chassé.Advantageously, it is possible to combine several floats linked to the rod according to different embodiments, to obtain different controls for the pressurized water supply in the ejection means. It is thus possible to combine several floats to obtain different volumes of flushed liquid.

De plus, la tige peut présenter deux rondelles qui permettent de commander l'arrivée d'eau pressurisée dans les moyens d'éjection.In addition, the rod may have two washers which make it possible to control the pressurized water supply in the ejection means.

En outre, le tube de Venturi peut comprendre un manchon, inséré à l'extrémité de la liaison au réseau d'eau pressurisée, présentant un rétrécissement, et peut comprendre une ouverture pouvant mettre en communication le liquide de chasse avec l'eau pressurisée circulant dans les moyens d'éjection, pour entraîner le liquide de chasse dans la colonne.In addition, the Venturi tube may include a sleeve, inserted at the end of the connection to the pressurized water network, having a narrowing, and may include an opening capable of putting the flushing liquid in communication with the pressurized water circulating in the ejection means, to drive the flushing liquid into the column.

Ainsi, en circulant au travers du rétrécissement des moyens d'éjection, l'eau pressurisée est accélérée et voit sa pression augmenter. En débouchant dans la colonne, qui présente une section supérieure à la section du rétrécissement des moyens d'éjection, l'eau pressurisée subit une détente brutale qui engendre un phénomène d'aspiration. De plus, la colonne est également ouverte sur le réservoir. Le liquide présent dans le réservoir est ainsi aspiré et entraîné dans la colonne.Thus, by circulating through the narrowing of the ejection means, the pressurized water is accelerated and sees its pressure increase. On emerging into the column, which has a section greater than the section of the narrowing of the ejection means, the pressurized water undergoes a sudden expansion which generates a suction phenomenon. In addition, the column is also open to the tank. The liquid present in the reservoir is thus sucked up and entrained in the column.

De la sorte, le tube de Venturi utilise la circulation d'eau pressurisée pour aspirer le liquide présent dans le réservoir de chasse.In this way, the Venturi tube uses pressurized water circulation to suck the liquid present in the cistern.

Selon un mode de réalisation préférentiel, la colonne peut présenter une collerette évasée pouvant délimiter, avec le manchon, l'ouverture mettant en communication le liquide de chasse avec l'eau pressurisée.According to a preferred embodiment, the column may have a flared flange that can delimit, with the sleeve, the opening placing the flushing liquid in communication with the pressurized water.

Ainsi le liquide présent dans le réservoir peut être aspiré dans la colonne.Thus the liquid present in the reservoir can be sucked into the column.

Préférentiellement, au moins trois entretoises peuvent être assemblées audit manchon et peuvent assurer le maintien de la colonne.Preferably, at least three spacers can be assembled to said sleeve and can maintain the column.

De la sorte les entretoises maintiennent la colonne tout en garantissant l'ouverture nécessaire à l'aspiration du liquide présent dans le réservoir.In this way the spacers maintain the column while guaranteeing the opening necessary for the suction of the liquid present in the reservoir.

Préférentiellement, les moyens d'éjections peuvent comprendre une conduite d'éjection formant un U, reliée à un réseau d'eau pressurisée, comprenant une partie descendante, un coude, le tube de Venturi et la colonne. Ce mode de réalisation permettant d'utiliser une arrivée d'eau pressurisée à hauteur standard.Preferably, the ejection means may comprise an ejection pipe forming a U, connected to a pressurized water network, comprising a descending part, an elbow, the Venturi tube and the column. This embodiment makes it possible to use a pressurized water inlet at standard height.

Grâce au robinet raccordé à un réseau d'eau pressurisée et aux moyens d'éjection, il est possible de réguler l'alimentation en eau des moyens d'éjection.Thanks to the tap connected to a pressurized water network and to the ejection means, it is possible to regulate the water supply to the ejection means.

De plus, le robinet connecté à un réseau d'eau pressurisée assure le remplissage en eau du réservoir.In addition, the tap connected to a pressurized water network fills the tank with water.

De la sorte le dispositif selon l'invention utilise deux robinets distincts pour remplir le réservoir de chasse et pour alimenter les moyens d'éjection.In this way, the device according to the invention uses two separate taps to fill the cistern and to supply the ejection means.

Selon un mode de réalisation préférentiel, la cuvette peut présenter une partie antérieure pouvant incorporer une cavité, et une partie postérieure pouvant incorporer deux parois latérales qui peuvent délimiter un évidement dans lequel est inséré le dispositif de chasse.According to a preferred embodiment, the bowl may have a front part which may incorporate a cavity, and a rear part which may incorporate two side walls which may delimit a recess in which the flushing device is inserted.

En outre, le fond du dispositif de chasse peut être positionné à une altitude inférieure ou égale à l'altitude du fond de la cavité de la cuvette.In addition, the bottom of the flushing device can be positioned at an altitude less than or equal to the altitude of the bottom of the cavity of the bowl.

En effet, l'utilisation de l'aspiration liée à l'effet Venturi pour vider le réservoir de chasse affranchit le dispositif selon l'invention d'un positionnement en hauteur du dispositif de chasse. Le dispositif selon l'invention permet donc de positionner le dispositif de chasse à une altitude libre par rapport au fond de la cavité de la cuvette. En outre, le positionnement du fond du dispositif de chasse à une altitude inférieure ou égale à l'altitude du fond de la cavité de la cuvette émancipe le dispositif selon l'invention des risques de fuites liés à la circulation de fluide par gravité qui doit nécessairement être fermée par un obturateur et permet également au dispositif selon l'invention d'être compact.Indeed, the use of suction linked to the Venturi effect to empty the cistern frees the device according to the invention from a height positioning of the flushing device. The device according to the invention therefore makes it possible to position the flushing device at a free altitude relative to the bottom of the cavity of the bowl. In addition, the positioning of the bottom of the flushing device at an altitude less than or equal to the altitude of the bottom of the cavity of the bowl emancipates the device according to the invention from the risks of leaks linked to the circulation of fluid by gravity which must necessarily be closed by a shutter and also allows the device according to the invention to be compact.

Ainsi, le liquide présent dans le réservoir de chasse se situe à la même altitude que la cuvette.Thus, the liquid present in the cistern is at the same altitude as the bowl.

De plus, le dispositif de chasse peut être entièrement inclus dans la partie postérieure de la cuvette, entre les deux parois latérales, la surface d'assise de la cuvette et la surface inférieure de ladite cuvette.In addition, the flushing device can be entirely included in the rear part of the bowl, between the two side walls, the seat surface of the bowl and the lower surface of said bowl.

De la sorte, le dispositif de chasse est entièrement incorporé dans la cuvette. Le dispositif selon l'invention est alors compact et sans risque de fuites causées par l'usage d'un obturateur.In this way, the flushing device is fully incorporated into the bowl. The device according to the invention is then compact and without risk of leaks caused by the use of a stopper.

Par ailleurs, un actionneur mécanique peut être adapté pour déclencher la fermeture du robinet d'eau pressurisée.Furthermore, a mechanical actuator can be adapted to trigger the closing of the pressurized water valve.

De plus, l'actionneur mécanique peut comprendre au moins un aimant et au moins un flotteur surnageant dans le liquide contenu dans le réservoir de chasse. Ledit au moins un aimant et ledit au moins au flotteur pouvant être adaptés pour déclencher la fermeture du robinet d'eau pressurisée.In addition, the mechanical actuator may include at least one magnet and at least one supernatant float in the liquid contained in the flush tank. Said at least one magnet and said at least one float can be adapted to trigger the closing of the pressurized water tap.

Ainsi lorsque le réservoir tend à être vide le robinet alimentant les moyens d'éjection est fermé.Thus, when the reservoir tends to be empty, the tap supplying the ejection means is closed.

Lors de la fixation de la cuvette 10 à un mur, la surface d'assise 18 est positionnée sensiblement paralléle au sol.When fixing the bowl 10 to a wall, the seat surface 18 is positioned substantially parallel to the ground.

La cuvette 10 comprend en outre, une cavité 11 destinée à recevoir des liquides et un déversoir 16 destiné à déverser l'eau chassée dans la cuvette pour la nettoyer.The bowl 10 further comprises a cavity 11 intended to receive liquids and a weir 16 intended to discharge the water driven into the bowl in order to clean it.

De plus, à proximité de la partie verticale 13, la cuvette 10 comprend un évidement 15 destiné à accueillir une dispositif de chasse 100In addition, close to the vertical part 13, the bowl 10 comprises a recess 15 intended to accommodate a flushing device 100

Le dispositif de chasse 100, que l'on peut voir sur les figures 2 à 4, comprend notamment un réservoir 101. Lorsque le réservoir 101 est installé, le fond dudit réservoir 101 est à une altitude similaire ou inférieure à l'altitude du fond de la cavité 11 de la cuvette 10.The hunting device 100, which can be seen on the figures 2 to 4 , notably comprises a tank 101. When the tank 101 is installed, the bottom of said tank 101 is at an altitude similar to or lower than the altitude of the bottom of the cavity 11 of the bowl 10.

Comme on va le voir, il s'agit d'une disposition importante de l'invention.As will be seen, this is an important provision of the invention.

De même, lorsque le réservoir 101 est installé, la partie haute du réservoir 101 peut être sensiblement à la même altitude que la surface d'assise 18 de la cuvette 10Similarly, when the tank 101 is installed, the upper part of the tank 101 can be substantially at the same altitude as the seating surface 18 of the bowl 10

Le reservoir 101 peut être réalisé en polymère adapté au stockage d'un liquide et peut être intégré dans la partie arrière 13 de la cuvette 10, entre les deux parois latérales 19.The tank 101 can be made of polymer suitable for storing a liquid and can be integrated into the rear part 13 of the bowl 10, between the two side walls 19.

Comme cela est visible sur la figure 2, un robinet de vidage 120 d'eau pressurisée est fixé dans la partie haute du réservoir 101. Le robinet 120 alimente une conduite d'éjection 110. La conduite d'éjection 110 présente une géométrie en U et se compose d'une partie tubulaire descendante 111, d'une partie tubulaire coudée 112 et d'une colonne tubulaire montante 114.As can be seen on the picture 2 , a pressurized water drain valve 120 is fixed in the upper part of the tank 101. The valve 120 supplies an ejection pipe 110. The ejection pipe 110 has a U-shaped geometry and consists of a tubular part descending 111, a bent tubular part 112 and a rising tubular column 114.

En outre, un coude d'éjection 115 est positionné à la sortie de la partie montante 114. Comme cela est observable en détail sur la figure 3, un tube de Venturi 130 est positionné entre la partie coudée 112 et la colonne 114 de la conduite 110.In addition, an ejection elbow 115 is positioned at the exit of the rising part 114. As can be seen in detail on the picture 3 , a Venturi tube 130 is positioned between the elbow portion 112 and the column 114 of the pipe 110.

Le tube de Venturi 130 comprend d'une part,un manchon de section tubulaire 131, présentant une section similaire à la section de la partie coudée 112, un rétrécissement conique de section 132 débouchant dans la colonne 114.The Venturi tube 130 comprises on the one hand, a sleeve of tubular section 131, having a section similar to the section of the bent part 112, a conical narrowing of section 132 opening into the column 114.

Dans le mode de réalisation ici présenté, quatres ailettes 133 sont fixées au manchon 131. La colonne 114 repose sur les quatres ailettes 133 de manière à présenter une ouverture cylindrique 134 dans la conduite d'ejection 110.In the embodiment presented here, four fins 133 are fixed to the sleeve 131. The column 114 rests on the four fins 133 so as to present a cylindrical opening 134 in the ejection pipe 110.

La commande du robinet de vidage 120 est assurée par un actionneur mécanique 125 piloté par un actionneur manuel grande chasse et un actionneur manuel petite chasse.The flushing valve 120 is controlled by a mechanical actuator 125 controlled by a full-flush manual actuator and a small-flush manual actuator.

L'actionneur mécanique 125 peut comprendre un flotteur petite chasse 128 fixé sur une tige descendante 126, et un flotteur grande chasse 127 glissant sur la colonne 114 et la tige 126.The mechanical actuator 125 may include a small flush float 128 fixed on a descending rod 126, and a large flush float 127 sliding on the column 114 and the rod 126.

Le flotteur grande chasse 127 et le flotteur petite chasse 128 peuvent être réalisé en polystyrène expansé ou en tout autre matériau présentant une densité plus faible que la densité de l'eau.The large flush float 127 and the small flush float 128 can be made of expanded polystyrene or any other material having a lower density than the density of water.

La tige 126 présente trois rondelles de pression 126A, 126B et 126C.Rod 126 has three pressure washers 126A, 126B and 126C.

Un levier 121 est positionné entre les rondelles 126A et 126B. Le levier 121 pilote le robinet de vidage 120.A lever 121 is positioned between washers 126A and 126B. Lever 121 controls drain valve 120.

La rondelle 126C est situé à proximité du flotteur grande chasse 127.The 126C washer is located near the large hunting float 127.

De plus, le flotteur grande chasse 127 est lié à un aimant 129 qui est positionné sur une paroi de la partie coudée 112.In addition, the big flush float 127 is linked to a magnet 129 which is positioned on a wall of the bent part 112.

En outre, comme cela est observable sur la figure 4, le dispositif de chasse 100 comprend un robinet de remplissage 140.Furthermore, as can be seen in the figure 4 , the flushing device 100 comprises a filling valve 140.

Le robinet de remplissage 140 permet le remplissage du réservoir 101 après une opération de chasse de l'eau.The filling valve 140 allows the filling of the reservoir 101 after a flushing operation.

Pour cela, le robinet de remplissage 140 est connecté à un réseau d'eau préssurisée.For this, the filling valve 140 is connected to a pressurized water network.

Comme cela est visible sur la figure 5, une vanne trois voies 180 relie les robinets 120 et 140 à un réseau d'eau pressurisée.As can be seen on the figure 5 , a three-way valve 180 connects the taps 120 and 140 to a pressurized water network.

Ainsi, cette vanne trois voies 180 permet d'alimenter succéssivement le robinet de vidage 120 lors du vidage du réservoir de chasse 101, puis d'alimenter le robinet de remplissage 140 afin remplir le réservoir 101.Thus, this three-way valve 180 makes it possible to successively supply the emptying valve 120 during the emptying of the flushing tank 101, then to supply the filling valve 140 in order to fill the tank 101.

Un flotteur de remplissage 141, installé glissant sur une colonne 142 actionne la fermeture du robinet de remplissage 140.A filling float 141, installed sliding on a column 142 actuates the closure of the filling valve 140.

Le fonctionnement du dispositif de toilettes 1 selon l'invention est le suivantThe operation of the toilet device 1 according to the invention is as follows

Il est précisé que la description qui va suivre part d'une situation dans laquelle le réservoir de chasse 101 est rempli d'eau.It is specified that the following description starts from a situation in which the cistern 101 is filled with water.

Lorsque l'actionneur petite chasse est enclenché, la tige 126 est déplacée de sorte que la rondelle 126B exerce une pression contre le levier 121 afin d'ouvrir le robinet de vidage 120.When the small flush actuator is engaged, rod 126 is moved so that washer 126B exerts pressure against lever 121 to open flush valve 120.

Le flotteur petite chasse 128, immergé dans le liquide de chasse exerce alors une pression sur la tige 126 qui maintient la rondelle 126B contre le levier 121.The small flush float 128, immersed in the flushing liquid then exerts pressure on the rod 126 which holds the washer 126B against the lever 121.

Lorsque l'actionneur grande chasse est enclenché, le flotteur grande chasse 127 est séparé de l'aimant 129.When the full flush actuator is engaged, the full flush float 127 is separated from the magnet 129.

En étant séparé de l'aimant 129, le flotteur grande chasse 127, immergé dans le liquide de chasse, exerce une poussée sur la rondelle 126C de la tige 126. La tige 126 est déplacée et la rondelle 126B appuie sur le levier 121 ce qui ouvre et maintient ouvert le robinet de vidage 120.By being separated from the magnet 129, the big flush float 127, immersed in the flushing liquid, exerts a thrust on the washer 126C of the rod 126. The rod 126 is moved and the washer 126B presses on the lever 121 which opens and keeps open the drain valve 120.

Quel que soit l'actionneur enclenché, lorsque l'eau pressurisée issue du robinet de vidage 120 circule dans le tube de Venturi 130, le rétrécissement de section 132 crée une accélération locale du fluide. En débouchant du rétrécissement de section 132 dans la colonne 114, l'eau ainsi accélérée subit une détente brutale qui engendre une aspiration du liquide environnant. L'ouverture 134 permet au fluide présent dans le réservoir 101 de pénétrer dans la colonne 114. De la sorte, lors du passage de l'eau préssurisée, l'aspiration générée par le tube de Venturi 130 entraîne le fluide, présent dans réservoir 101, dans la colonne 114.Whatever the activated actuator, when the pressurized water from the drain valve 120 circulates in the Venturi tube 130, the narrowing of section 132 creates a local acceleration of the fluid. On emerging from the constriction of section 132 in the column 114, the water thus accelerated undergoes a sudden expansion which generates a suction of the surrounding liquid. The opening 134 allows the fluid present in the tank 101 to enter the column 114. In this way, during the passage of the pressurized water, the suction generated by the Venturi tube 130 draws the fluid present in the tank 101 , in column 114.

Le fluide ainsi aspiré dans la colonne 114 est ensuite évacué, au travers du coude 115 et du déversoir 16, dans la cavité 11 de la cuvette 10.The fluid thus sucked into the column 114 is then evacuated, through the elbow 115 and the weir 16, into the cavity 11 of the bowl 10.

Le coude 115 garantit la bonne orientation du flux liquide lors de son évacuation dans la cavité 11 de la cuvette 10.The elbow 115 guarantees the correct orientation of the liquid flow during its evacuation into the cavity 11 of the bowl 10.

Dans le mode de réalisation ici présenté, le robinet de vidage 120 est connecté au réseau d'eau courante et alimente la conduite d'éjection 110. Ainsi l'eau issue du robinet de vidage 120 est à une pression sensiblement égale à trois bars.In the embodiment presented here, the drain valve 120 is connected to the running water network and supplies the ejection pipe 110. Thus the water from the drain valve 120 is at a pressure substantially equal to three bars.

Dans le cas d'une petite chasse, lorsque le niveau de liquide dans le réservoir 101 est tel que le flotteur petite chasse 128 n'est plus complètement immergé, le flotteur petite chasse 128 n'exerce plus de pression sur la tige 126, la rondelle 126A est alors repositionnée par gravité contre le levier 121. Le robinet de vidage 120 est alors fermé.In the case of a small flush, when the level of liquid in the reservoir 101 is such that the small flush float 128 is no longer completely submerged, the small flush float 128 no longer exerts pressure on the rod 126, the washer 126A is then repositioned by gravity against the lever 121. The drain valve 120 is then closed.

Dans le cas d'une grande chasse, lorsque le niveau de liquide dans le réservoir 101 est tel que le flotteur grande chasse 127 n'est plus immergé, le flotteur grande chasse est repositionné contre l'aimant 129 et la rondelle 126A est repositionnée par gravité contre le levier 121. Le robinet de vidage 120 est fermé.In the case of a big flush, when the level of liquid in the tank 101 is such that the big flush float 127 is no longer submerged, the big flush float is repositioned against the magnet 129 and the washer 126A is repositioned by gravity against lever 121. Drain valve 120 is closed.

Pour remplir le réservoir 101 après une chasse, le robinet de remplissage 140 est ouvert jusqu'à ce que le flotteur de remplissage 141 actionne la fermeture dudit robinet de remplissage 140.To fill the tank 101 after a flush, the filling valve 140 is open until the filling float 141 actuates the closure of said filling valve 140.

Le dispositif de toilettes selon l'invention offre donc l'avantage de pouvoir positionner le réservoir derrière ou sous la cuvette. Il est ainsi possible d'obtenir un dispositif de toilettes compactes. En outre, la configuration du dispositif de chasse permet d'éviter des fuites de liquide dans la cuvette.The toilet device according to the invention therefore offers the advantage of being able to position the tank behind or under the bowl. It is thus possible to obtain a compact toilet device. In addition, the configuration of the flushing device makes it possible to avoid liquid leaks into the bowl.
