Description

La présente invention concerne un dispositif d'évacuation des eaux, encore appelé ensemble de vidage, en particulier pour des appareils sanitaires, par exemple une bonde pour bac receveur de douche.The present invention relates to a water evacuation device, also called emptying assembly, in particular for sanitary appliances, for example a bung for shower tray tray.

Les bacs receveur de douche tels que conçus jusqu'à ces dernières années étaient prévus pour recevoir une hauteur d'eau relativement importante. Le problème du faible débit des dispositifs d'évacuation était secondaire dans la mesure où une quantité relativement importante d'eau pouvait s'accumuler dans l'enceinte du bac de douche.The shower trays as designed until recent years were designed to receive a relatively large water level. The problem of the low flow of the evacuation devices was secondary in that a relatively large amount of water could accumulate in the enclosure of the shower tray.

Les problèmes rencontrés avec les bacs receveurs traditionnels tenaient d'une part à l'encrassage des bondes résultant pour une bonne part des restrictions apportées par les sections de passage des eaux à évacuer, et d'autre part au nettoyage des parois verticales desdits bacs receveurs et à la difficulté d'accès pour l'utilisateur de la douche résultant de la marche importante constituée par ses parois verticales.The problems encountered with the traditional receiving bins were on the one hand to the fouling of the bungs resulting for a large part of the restrictions brought by the sections of passage of water to be evacuated, and on the other hand to the cleaning of the vertical walls of said bins receivers and the difficulty of access for the user of the shower resulting from the significant step constituted by its vertical walls.

L'apparition de bacs receveurs extra-plats plus esthétiques, mais aussi plus faciles à enjamber et à nettoyer, devait cependant modifier la perception des dispositifs d'évacuation des eaux puisqu'avec la nécessité de maintenir en permanence lors de l'utilisation une très faible hauteur d'eau, il fallait créer un dispositif d'évacuation de faible encombrement dans sa hauteur, facile à nettoyer pour éviter tout risque d'obturation et assurant un débit fortement accru par rapport aux dispositifs d'évacuation des eaux existants.The appearance of extra-flat trays more aesthetic, but also easier to step over and clean, however, had to change the perception of water evacuation devices since with the need to maintain permanently during use a very low water height, it was necessary to create a discharge device of small size in its height, easy to clean to avoid any risk of clogging and providing a greatly increased flow compared to existing drainage devices.

Le brevet EP 1 034 337 décrit un dispositif d'évacuation des eaux, encore appelé ensemble de vidage, constitué d'un gobelet central dans lequel débouche une ouverture d'amenée des eaux recouverte d'un capot, d'un tube plongeur amovible inséré dans le gobelet central, d'une canalisation ou tubulure d'évacuation ainsi que d'un canal d'évacuation communiquant avec le gobelet central et entourant celui-ci, le canal d'évacuation débouchant sur un raccord vers la tubulure d'évacuation. Le canal d'évacuation est unique et présente une forme hélicoïdale descendant autour du gobelet central depuis un point haut jusqu'à un point bas de communication avec la tubulure d'évacuation, lesdits points haut et bas étant sensiblement alignés selon une verticale.The patent EP 1 034 337 discloses a water evacuation device, also called emptying assembly, consisting of a central cup in which opens a water inlet opening covered with a hood, a removable plunger inserted into the central cup, d a pipe or evacuation pipe and a discharge channel communicating with the central cup and surrounding it, the evacuation channel opening on a connection to the evacuation pipe. The escape channel is unique and has a helical shape descending around the central cup from a high point to a point communication bottom with the evacuation pipe, said high and low points being substantially aligned in a vertical direction.

Le système décrit dans le brevet EP 1 034 337 permet avantageusement d'obtenir un écoulement accéléré de l'eau sous forme d'un flux unique s'écoulant dans un canal d'évacuation vers une canalisation d'évacuation. Avantageusement, ce système permet d'obtenir un débit important. Le système proposé par le brevet EP 1 034 337 résulte en une obturation partielle de la section libre disponible au vu des besoins de stabilité de la fixation dans le receveur. Un autre inconvénient du système proposé par le brevet EP 1 034 337 réside dans le fait qu'un accès limité est possible à l'intérieur de la bonde. Ceci peut devenir problématique pour le nettoyage du système.The system described in the patent EP 1 034 337 advantageously makes it possible to obtain an accelerated flow of water in the form of a single flow flowing in a discharge channel towards an evacuation pipe. Advantageously, this system makes it possible to obtain a high flow rate. The system proposed by the patent EP 1 034 337 results in a partial closure of the free section available in view of the stability requirements of the attachment in the receiver. Another disadvantage of the system proposed by the patent EP 1 034 337 lies in the fact that limited access is possible inside the bung. This can become problematic for the cleaning of the system.

La présente invention a pour but de proposer un dispositif d'évacuation des eaux ou ensemble de vidage, en particulier pour appareils sanitaires, permettant de tenir un débit d'eau important tout en fournissant un maintien suffisant du capot.The present invention aims to provide a water evacuation device or emptying assembly, in particular for sanitary appliances, for maintaining a high flow of water while providing sufficient maintenance of the hood.

Un autre objet de la présente invention consiste à proposer un dispositif d'évacuation des eaux avec une option d'accès à la tubulure de raccordement ou même jusqu'à la canalisation à laquelle le dispositif d'évacuation des eaux est relié.Another object of the present invention is to provide a water evacuation device with an access option to the connecting pipe or even to the pipe to which the drainage device is connected.

A cet effet, l'invention propose un dispositif d'évacuation des eaux tel que défini par les termes de la revendication 1.For this purpose, the invention proposes a device for discharging water as defined by the terms of claim 1.

En prévoyant une fixation centrale, dans le centre du boitier, une section utile pour l'évacuation de l'eau importante est obtenue, permettant un débit d'évacuation supérieur aux systèmes connus dans lequel le plateau est fixé sur un couvercle monté sur le boitier, latéralement, de manière périphérique au boitier.By providing a central fixation, in the center of the housing, a useful section for the evacuation of water is obtained, allowing a higher evacuation rate to known systems in which the tray is fixed on a cover mounted on the housing , laterally, peripherally to the housing.

Selon un mode de réalisation, l'élément de fixation est sensiblement au centre du plateau et l'élément de fixation complémentaire se trouve sensiblement au centre du gobelet. Ainsi, un montage simple peut être réalisé.According to one embodiment, the fixing element is substantially in the center of the plate and the complementary fixing element is substantially in the center of the cup. Thus, a simple assembly can be realized.

De manière avantageuse, l'élément de fixation est une vis pour coopérer avec un filetage correspondant dans une ouverture du gobelet, sensiblement au centre du gobelet. Un tel agencement permet un montage et un démontage facile et rapide, une seule vis étant à positionner et à visser.Advantageously, the fixing element is a screw for cooperating with a corresponding thread in an opening of the cup, substantially in the center of the cup. Such an arrangement allows a quick and easy assembly and disassembly, a single screw being positioned and screwed.

Selon un aspect de la présente invention, les tubes plongeurs sont au nombre de trois et/ou en forme de section d'anneau et sont répartis dans une pluralité de compartiments. Ainsi, une pluralité de tubes plongeurs dans une pluralité de compartiments répartis autour de la vis centrale permet un accès important à l'intérieur de la bonde. Par ailleurs, la pluralité de compartiments permet de répartir les forces de serrage de la vis de fixation centrale.According to one aspect of the present invention, the plunger tubes are three in number and / or ring-shaped and are distributed in a plurality of compartments. Thus, a plurality of dip tubes in a plurality of compartments distributed around the central screw allows significant access to the interior of the bung. Moreover, the plurality of compartments makes it possible to distribute the clamping forces of the central fixing screw.

Selon un aspect de la présente invention, un compartiment de la pluralité de compartiments avec une partie d'immersion de tube plongeur et une partie d'accès à la canalisation avec une ouverture supérieure est prévu. Avantageusement, un passage d'accès pour furet peut être obtenu, ce qui permet d'améliorer encore l'accès à la canalisation.According to one aspect of the present invention, a compartment of the plurality of compartments with a dip tube immersion portion and a pipe access portion with an upper opening is provided. Advantageously, an access passage for ferret can be obtained, which further improves access to the pipeline.

Dans un mode de réalisation, la partie d'immersion de tube plongeur et la partie d'accès à la canalisation avec une ouverture supérieure sont sensiblement de section correspondante.In one embodiment, the dip tube immersion portion and the pipe access portion with an upper opening are substantially of corresponding section.

Selon un aspect de la présente invention, un tube plongeur reçu dans ledit compartiment comprend une partie immersible, destinée à être insérée dans la partie d'immersion, ainsi qu'une partie de bouchon, adjacente à la partie immersible, pour boucher la partie d'accès à la canalisation. En prévoyant un tube plongeur avec un bouchon, il n'y a plus besoin de modifier les compartiments de la bonde elle-même.According to one aspect of the present invention, a dip tube received in said compartment comprises an immersible part, intended to be inserted into the immersion part, as well as a plug part, adjacent to the immersible part, to plug the part of the immersible part. access to the pipeline. By providing a dip tube with a plug, there is no need to change the compartments of the bung itself.

En prévoyant que la partie de bouchon présente une surface de bouchon légèrement inclinée vers la partie immersible du tube plongeur, l'évacuation de l'eau vers la partie immersible du tube plongeur peut être facilitée.By providing that the plug portion has a plug surface slightly inclined toward the immersible portion of the dip tube, the discharge of water to the immersible portion of the dip tube can be facilitated.

Selon un aspect de l'invention, des moyens détrompeurs sont prévus afin de faciliter le positionnement du plateau et/ou l'arrangement de tube(s) plongeur(s).According to one aspect of the invention, polarizing means are provided to facilitate the positioning of the plate and / or the tube arrangement (s) plunger (s).

Selon un aspect de l'invention, l'ouverture d'amenée des eaux est recouverte d'un capot fixé par serrage au niveau de la tête de vis. Ainsi, les fixations sont centrales, ce qui permet également de monter facilement le capot.According to one aspect of the invention, the water supply opening is covered with a cover fixed by clamping at the screw head. Thus, the fasteners are central, which also makes it easy to mount the hood.

Selon un autre aspect de l'invention, le capot peut être prévu pour fixer ou immobiliser le ou les tube(s) plongeur(s) et/ou la surface de bouchon.According to another aspect of the invention, the cap may be provided to fix or immobilize the plunger tube (s) and / or the cap surface.

Avantageusement, le boitier monobloc peut être moulé avec au moins un joint intégré. Le boitier peut être bi matière, et comprendre deux parties soudées avec un joint périphérique.Advantageously, the one-piece housing can be molded with at least one integrated seal. The case can be bi material, and include two parts welded with a peripheral seal.

The bung is fixed in an orifice formed in the bottom of a tray with the aid of the plate 10, screwable on the housing 1.

Selon l'invention, une fixation centrale 20 s'étend sensiblement depuis le centre du plateau 10, à la verticale de celui-ci, sous forme de vis dans le mode de réalisation représenté, pour une fixation du plateau sur le boitier 1.According to the invention, a central fastening 20 extends substantially from the center of the plate 10, vertically to it, in the form of a screw in the embodiment shown, for fixing the plate on the housing 1.

Des joints multifonction sont prévus pour assurer l'étanchéité. Par exemple, un joint 36 pour l'étanchéité à l'air du boitier est interposé entre le dessus du boitier et le gobelet central, autour de l'ouverture 21. De même, un joint torique 37 est prévu qui sert à la tenue et au maintien du capot 9, qui repose sur le plateau 10 et est fixé par serrage sur le joint torique 37 monté sur la tête de vis 20. Le boitier 1 comprend également des joints moulés sur le dessus du boîtier, ainsi qu'un joint pour assurer l'étanchéité de la soudure entre la partie haute et la partie basse du boîtier 1.Multi-function gaskets are provided for sealing. For example, a seal 36 for the airtightness of the housing is interposed between the top of the housing and the central cup, around the opening 21. Similarly, an O-ring 37 is provided which is used for holding and maintaining the cover 9, which rests on the plate 10 and is fixed by clamping on the O-ring 37 mounted on the screw head 20. The housing 1 also comprises molded joints on the top of the housing, and a seal for seal the weld between the upper part and the lower part of the case 1.

Le gobelet central 2 comprend une paroi de fond 23, une paroi latérale 24 interne, entourant une ouverture centrale 21, et une paroi latérale externe 25, reliée au canal d'évacuation 3.The central cup 2 comprises a bottom wall 23, an internal lateral wall 24, surrounding a central opening 21, and an external lateral wall 25, connected to the evacuation channel 3.

Dans le mode de réalisation représenté, le gobelet central 2 comprend trois compartiments 2a, 2b, 2c, répartis autour d'une ouverture centrale 21. L'ouverture centrale 21 est munie d'un filetage 27 correspondant prévu pour coopérer avec la vis centrale 20 du plateau 10.In the embodiment shown, the central cup 2 comprises three compartments 2a, 2b, 2c, distributed around a central opening 21. The central opening 21 is provided with a corresponding thread 27 designed to cooperate with the central screw 20 of the board 10.

Ainsi, contrairement aux systèmes de l'art antérieur dans lequel le plateau est fixé sur le boitier, latéralement, de manière périphérique au boitier, la présente invention envisage une fixation centrale dans le centre du boitier 1. Avantageusement, une section utile plus importante est obtenue, permettant un débit d'évacuation supérieur aux systèmes connus.Thus, unlike systems of the prior art in which the tray is fixed on the housing, laterally, peripherally to the housing, the present invention contemplates a central fixation in the center of the housing 1. Advantageously, a larger useful section is obtained, allowing an evacuation flow rate higher than the known systems.

Les trois compartiments 2a, 2b, 2c sont conçus pour recevoir trois tubes plongeurs 11a, 11b, 11c. Les tubes plongeurs 11a, 11b, 11c peuvent comprendre chacun une sorte de panier filtrant. L'un ou les trois tubes plongeurs 11a, 11b, 11c peuvent être amovibles, par exemple grâce à un dispositif de préhension (non représenté).The three compartments 2a, 2b, 2c are designed to receive three plunger tubes 11a, 11b, 11c. The plunger tubes 11a, 11b, 11c may each comprise a sort of filter basket. One or three plunger tubes 11a, 11b, 11c may be removable, for example by means of a gripping device (not shown).

Le plateau 10 comprend ainsi trois ouvertures de passage 10a, 10b, 10c, pour permettre le passage des tubes plongeurs 11a, 11b, 11c.The plate 10 thus comprises three passage openings 10a, 10b, 10c, to allow the passage of the plunger tubes 11a, 11b, 11c.

Comme illustré sur la figure 6, des moyens détrompeurs 80 sont prévus afin de faciliter le positionnement du plateau sur le corps de bonde. Les moyens détrompeurs 80 comprennent un picot 80 s'étendant du plateau 10, prévu pour venir se loger dans un évidement complémentaire du corps de bonde. Bien entendu, cet exemple n'est pas limitatif et tout autre moyen de détrompage peut être envisagé.As illustrated on the figure 6 , polarizing means 80 are provided to facilitate the positioning of the plate on the bung body. The polarizing means 80 comprise a pin 80 extending from the plate 10, provided to be housed in a recess complementary to the bung body. Of course, this example is not limiting and any other keying means may be considered.

Les tubes plongeurs 11a, 11b, 11c peuvent être munis de grillage filtrant, au fond, afin de laisser passer l'eau mais de retenir les saletés.The plunger tubes 11a, 11b, 11c may be provided with filtering mesh, at the bottom, in order to let the water pass but to retain the dirt.

Une lèvre 31a, 31b, 31c de maintien et d'étanchéité est également disposée sur chaque surface supérieure de chacun des compartiments 2a, 2b, 2c. La lèvre permet le maintien de chacun des tubes plongeurs 11a, 11b, 1 le par adhérence et/ou par friction, tout en assurant une bonne étanchéité.A lip 31a, 31b, 31c for holding and sealing is also disposed on each upper surface of each of the compartments 2a, 2b, 2c. The lip makes it possible to hold each of the plunger tubes 11a, 11b, 1 by adhesion and / or friction, while ensuring a good seal.

L'homme du métier comprendra qu'au moins un tube plongeur fixé à une fixation centrale permet d'assurer des sections de passage suffisantes pour un débit élevé.Those skilled in the art will understand that at least one dip tube attached to a central fixation ensures sufficient passage sections for high flow.

Dans le mode de réalisation représenté sur les figures 1 à 3, trois compartiments avec trois tubes plongeurs sont envisagés. Un gobelet central avec trois compartiments permet de bien transmettre les forces de serrage. Bien entendu, cet exemple n'est pas limitatif et la présente invention propose d'utiliser au moins un tube plongeur fixé à une fixation centrale.In the embodiment shown on the Figures 1 to 3 three compartments with three dip tubes are envisaged. A central cup with three compartments makes it possible to transmit the clamping forces. Of course, this example is not limiting and the present invention proposes to use at least one dip tube attached to a central fixation.

Dans l'exemple représenté, la fixation centrale est une vis 20. Bien entendu, d'autres types de fixation peuvent être envisagés, tel qu'une fixation par coopération d'éléments de fixation male et femelles.In the example shown, the central fixing is a screw 20. Of course, other types of attachment may be envisaged, such as a fixing by cooperation of male and female fasteners.

L'entrée du flux des eaux à l'intérieur de l'ensemble de vidage se fait par les interstices 8 ménagés entre le capot 9 et le plateau 10. L'eau chute à l'intérieur des tubes plongeurs 11a, 11b, 11c, autour de la vis centrale 20.The entry of the flow of water inside the emptying assembly is done by the interstices 8 formed between the cover 9 and the plate 10. The water falls inside the plunger tubes 11a, 11b, 11c, around the central screw 20.

A l'extrémité inférieure des tubes plongeurs 11a, 11b, 11c, l'eau vient buter contre le fond des compartiments respectifs 2a, 2b, 2c du gobelet 2 puis subit une rotation à 180° grâce à un segment en arc de cercle 23 ouvert vers le haut, ménagé entre le fond et la paroi verticale 25 des compartiments du gobelet 2. Le flux ainsi dévié remonte entre la paroi externe des tubes plongeurs 11a, 11b, 11c et la face interne de la paroi verticale 25 du gobelet 2.At the lower end of the plunger tubes 11a, 11b, 11c, the water abuts against the bottom of the respective compartments 2a, 2b, 2c of the cup 2 and is then rotated 180 ° by means of an open circular segment 23 upwardly, arranged between the bottom and the vertical wall 25 of the compartments of the cup 2. The flow thus diverted back up between the outer wall of the plunger tubes 11a, 11b, 11c and the inner face of the vertical wall 25 of the cup 2.

Lorsque le gobelet central 2 est rempli, les eaux débordent au-dessus de la paroi verticale 25 dudit gobelet 2 et tombent dans le canal d'évacuation 3, qui comprend deux branches sensiblement symétrique, de forme hélicoïdale périphérique, formant deux descentes symétriques se rejoignant au l'orifice de sortie des eaux du canal d'évacuation 3 communiquant avec le raccord vers la tubulure d'évacuation 4. L'eau suit ainsi un mouvement descendant, accélérateur, vers l'orifice de sortie des eaux du canal d'évacuation 3 communiquant avec le raccord vers la tubulure d'évacuation 4.When the central cup 2 is filled, the water overflows above the vertical wall 25 of said cup 2 and falls into the evacuation channel 3, which comprises two substantially symmetrical branches of helical peripheral shape, forming two symmetrical descents joining together at the outlet of the water outlet channel 3 communicating with the connection to the discharge pipe 4. The water thus follows a downward movement, accelerator, to the outlet of the water outlet channel 3 communicating with the connection to the evacuation pipe 4.

Ainsi, l'agencement avec trois tubes plongeurs amovibles, regroupés autour d'une fixation centrale, permet d'obtenir des débits importants. De plus, l'utilisation d'une vis centrale autorise une mise en place facilitée, un seul vissage étant nécessaire lors de l'installation.Thus, the arrangement with three removable plunger tubes, grouped around a central fixation, makes it possible to obtain high flow rates. In addition, the use of a central screw allows easy installation, one screwing being necessary during installation.

Les figures 4 et 5 représentent un dispositif d'évacuation des eaux 200 ou ensemble de vidage des eaux, en particulier pour des appareils sanitaires, selon un autre aspect de la présente invention.The figures 4 and 5 represent a water evacuation device 200 or water discharge assembly, in particular for sanitary appliances, according to another aspect of the present invention.

Dans le mode de réalisation des figures 4 et 5, le dispositif d'évacuation des eaux ou ensemble de vidage des eaux est une bonde de douche 200 qui diffère essentiellement de la bonde de douche 100 des figures 1 à 3 en ce qu'un accès à la canalisation est prévu, pour permettre par exemple le passage d'un furet de plomberie.In the embodiment of figures 4 and 5 , the drainage device or water discharge assembly is a shower bung 200 which differs essentially from the shower bung 100 of the Figures 1 to 3 in that an access to the pipeline is provided, to allow for example the passage of a plumbing ferret.

Dans le mode de réalisation représenté, la bonde 200 présente une ouverture d'amenée définie par des interstices 208 ménagés entre un capot 209 de la bonde et un plateau 210 portés par un boîtier 201, le plateau 210 permettant la fixation dans un bac de douche (non représenté). Le boîtier 201, par exemple en matière plastique, préférentiellement en polypropylène, comprend un gobelet central 202 autour duquel est accolé extérieurement un canal d'évacuation 203 qui présente une forme hélicoïdale débouchant sur un orifice de sortie des eaux rattaché à un raccord vers une canalisation ou tubulure d'évacuation 204.In the embodiment shown, the bung 200 has a feed opening defined by gaps 208 formed between a cover 209 of the bung and a plate 210 carried by a housing 201, the plate 210 for fixing in a shower tray (not shown) The housing 201, for example made of plastic material, preferably made of polypropylene, comprises a central cup 202 around which is joined externally a discharge channel 203 which has a helical shape opening onto a water outlet orifice attached to a connection to a pipe or evacuation tubing 204.

Une fixation centrale 220 s'étend sensiblement depuis le centre du plateau 210, à la verticale de celui-ci, sous forme de vis dans le mode de réalisation représenté, pour une fixation du plateau sur le boitier 201.A central fixing 220 extends substantially from the center of the plate 210, to the vertical thereof, in the form of a screw in the embodiment shown, for fixing the plate on the housing 201.

Le gobelet central 202 comprend une paroi de fond 223, une paroi 224 interne, sensiblement verticale, entourant une ouverture centrale 221, et une paroi périphérique externe 225, reliée au canal d'évacuation 203.The central cup 202 comprises a bottom wall 223, a substantially vertical inner wall 224 surrounding a central opening 221, and an outer peripheral wall 225 connected to the discharge channel 203.

Dans le mode de réalisation représenté, le gobelet central 202 comprend trois compartiments 202a, 202b, 202c, répartis autour d'une ouverture centrale 221. L'ouverture centrale 221 est munie d'un filetage 227 correspondant prévu pour coopérer avec la vis centrale 220 du plateau 210.In the embodiment shown, the central cup 202 comprises three compartments 202a, 202b, 202c, distributed around a central opening 221. The central opening 221 is provided with a corresponding thread 227 provided to cooperate with the central screw 220 of the tray 210.

Les trois compartiments 202a, 202b, 202c sont conçus pour recevoir trois tubes plongeurs 211a, 211b, 211c. Les tubes plongeurs 211a, 211b, 211c peuvent comprendre chacun une sorte de panier filtrant. Les trois tubes plongeurs 211a, 211b, 211c peuvent être amovibles, par exemple grâce à un dispositif de préhension (non représenté).The three compartments 202a, 202b, 202c are designed to receive three plunger tubes 211a, 211b, 211c. The plunger tubes 211a, 211b, 211c may each comprise a sort of filter basket. The three plunger tubes 211a, 211b, 211c may be removable, for example by means of a gripping device (not shown).

L'utilisation d'une fixation centrale, interne au boitier, sensiblement en position centrale, permet également de libérer l'accès au centre de la bonde, sans avoir à démonter celle-ci. En particulier, afin de créer une ouverture 250 d'accès à la canalisation, le compartiment 202a a une géométrie modifiée. Le compartiment comprend une partie 251 d'immersion de tube plongeur et une partie d'accès à la canalisation 252, séparée par une cloison 253. La partie d'accès à la canalisation 252 présente ainsi une ouverture supérieure 254, donnant sur un passage d'accès débouchant sur l'orifice de sortie.The use of a central fastener, internal to the housing, substantially in the central position, also frees access to the center of the bung, without having to disassemble it. In particular, in order to create an access opening 250 to the pipe, the compartment 202a has a modified geometry. The compartment comprises a dip tube immersion portion 251 and an access portion to the pipe 252, separated by a partition 253. The access part of the pipe 252 thus has an upper opening 254, giving onto a passage of access leading to the outlet port.

Le tube plongeur correspondant comprend ainsi une partie immersible 261, destinée à être insérée dans la partie d'immersion dudit compartiment, ainsi qu'une partie de bouchon 262, adjacente à la partie immersible 261, pour boucher l'accès à la canalisation 252.The corresponding dip tube thus comprises an immersible portion 261, intended to be inserted into the immersion portion of said compartment, and a plug portion 262, adjacent to the immersible portion 261, to block access to the pipe 252.

Les deux parties 261, 262, peuvent être en un seul bloc ou en deux parties indépendantes ou articulées.The two parts 261, 262 can be in one block or in two independent or articulated parts.

Comme illustrée à la figure 4, la partie de bouchon 262 est essentiellement une surface, légèrement inclinée vers la partie immersible 261 du tube plongeur, pour permettre l'évacuation de l'eau vers la partie immersible du tube plongeur.As illustrated in figure 4 , the plug portion 262 is substantially a surface, slightly inclined towards the immersible portion 261 of the dip tube, to allow the evacuation of water to the immersible portion of the dip tube.

Un joint d'étanchéité peut être également prévu sur le boitier et/ou sur le tube plongeur ou les tubes plongeurs , en particulier afin d'empêcher une remontée d'odeur d'air vicié.A seal may also be provided on the housing and / or on the dip tube or the plunger tubes, in particular to prevent a return of stale air odor.

Ainsi, en prévoyant un tube plongeur avec bouchon, un accès à la canalisation est obtenu, permettant un passage pour un furet de plomberie par exemple.Thus, by providing a dip tube with cap, access to the pipe is obtained, allowing passage for a plumbing ferret for example.

Cette invention n'est pas limitée à l'exemple de réalisation décrit ci-dessus mais elle en englobe toutes les variantes. De plus, l'invention a été décrite avec une bonde de douche. L'invention s'applique également au vidage des éviers, à des siphons de sol, à des évacuations d'eau pluviale de toiture, etc.This invention is not limited to the embodiment described above but encompasses all variants. In addition, the invention has been described with a shower bung. The invention also applies to the emptying of sinks, floor siphons, evacuations rainwater roofing, etc.
