Description
La présente invention se rapporte au domaine des dispositifs d'évacuation des eaux type siphons tel que pour douche sans y être limité. Plus particulièrement, la présente invention concerne un dispositif d'évacuation des eaux muni d'un clapet mobile anti-odeur.The present invention relates to the field of water drainage type siphons such as for shower without being limited thereto. More particularly, the present invention relates to a water evacuation device provided with a movable anti-odor valve.
On connait déjà des siphons anti-odeur. Le document
D'autres systèmes anti-odeur dits à garde d'eau utilisent un pot mobile avec un niveau d'eau minimum dans le corps évitant à l'air vicié du réseau de pénétrer dans l'habitation. Afin d'éviter les risques d'évaporation de la garde d'eau, un système de clapet mobile fermant le siphon et empêchant l'évaporation de l'eau a déjà été proposé.Other so-called water-resistant anti-odor systems use a mobile pot with a minimum water level in the body to prevent stale air from entering the home. To avoid the risk of evaporation of the water guard, a movable valve system closing the siphon and preventing the evaporation of water has already been proposed.
Les systèmes existants s'appuient sur l'utilisation de mécanisme pouvant perdre de leur efficacité dans le temps : perte de raideur de ressort, perte d'élasticité de membrane silicone, usure mécanique.Existing systems rely on the use of mechanisms that can lose their effectiveness over time: loss of spring stiffness, loss of elasticity of silicone membrane, mechanical wear.
Un objet de la présente invention est de proposer un dispositif d'évacuation des eaux avec un système anti-odeur qui est d'une part robuste et durable et d'autre part, en position ouverte, favorise l'écoulement.An object of the present invention is to provide a water evacuation device with an anti-odor system which is on the one hand robust and durable and on the other hand, in the open position, promotes flow.
A cet effet, l'invention propose un dispositif d'évacuation des eaux comprenant un corps creux, avec un fond, une paroi périphérique munie d'un orifice d'évacuation latérale ou verticale, et une ouverture supérieure d'amenée d'eau, un dispositif anti-odeur, comprenant un clapet mobile entre une position ouverte, permettant le passage de l'eau dans le corps du dispositif d'évacuation des eaux entre l'ouverture d'amenée et l'orifice d'évacuation, et une position fermée, bloquant le passage de l'eau et la remontée des odeurs entre l'ouverture d'entrée et l'orifice d'évacuation. Un dispositif de maintien en position fermée pour maintenir le clapet en position fermée et un moyen magnétique de rappel en position fermée, adapté pour rappeler le clapet mobile vers la position fermée sont prévus. Le dispositif d'évacuation des eaux comprend un dispositif d'inclinaison de clapet, adapté pour orienter angulairement-incliner le clapet par rapport au fond du corps, en position ouverte.For this purpose, the invention proposes a water evacuation device comprising a hollow body, with a bottom, a peripheral wall provided with a lateral or vertical discharge orifice, and an upper opening for supplying water, an anti-odor device, comprising a valve movable between an open position, allowing the passage of water in the body of the drainage device between the supply opening and the discharge orifice, and a position closed, blocking the passage of water and the rise of odors between the inlet opening and the outlet. A holding device in the closed position to maintain the valve in the closed position and a magnetic return means in the closed position, adapted to return the movable valve to the closed position are provided. The water evacuation device comprises a valve tilting device adapted to angularly orientate-tilt the valve relative to the bottom of the body, in the open position.
Selon un aspect de l'invention, le dispositif de maintien en position fermée comprend un premier élément magnétique sur le clapet mobile interagissant en attraction avec un deuxième élément magnétique solidaire du corps. De préférence, le moyen magnétique de rappel en position fermée comprend un troisième élément magnétique, le premier élément magnétique et le troisième élément magnétique exerçant une force de répulsion entre eux.According to one aspect of the invention, the holding device in the closed position comprises a first magnetic element on the movable valve interacting in attraction with a second magnetic element integral with the body. Preferably, the magnetic return means in the closed position comprises a third magnetic element, the first magnetic element and the third magnetic element exerting a repulsive force between them.
Des éléments magnétiques sont avantageusement robustes et fiables, ce qui assure la bonne tenue mécanique dans le temps du dispositif d'évacuation des eaux. De plus, un moyen de rappel en position fermée évite au clapet de ne descendre trop bas ou de rester immobilisé par rapport à sa position fermée et de tomber au fond du dispositif d'évacuation des eaux par exemple. Le clapet ne risque pas de rester en position ouverte grâce à au troisième élément magnétique, inférieur, qui le repousse pour lui permettre de « raccrocher » le magnétisme du deuxième élément magnétique de maintien en position fermée.Magnetic elements are advantageously robust and reliable, which ensures the good mechanical strength over time of the drainage device. In addition, a return means in the closed position prevents the valve from going down too low or remaining immobilized with respect to its closed position and falling to the bottom of the water evacuation device for example. The valve is not likely to remain in the open position thanks to the third magnetic element, lower, which pushes it to allow it to "hang up" the magnetism of the second magnetic holding member in the closed position.
Selon un mode de réalisation, un dispositif d'inclinaison de clapet est prévu, qui est adapté pour incliner le clapet vers l'orifice d'évacuation et orienter le flux d'eau vers l'orifice d'évacuation. Un tel dispositif d'inclinaison de clapet permet d'assurer un bon écoulement et débit du flux d'eau vers l'orifice d'évacuation, en limitant les turbulences.According to one embodiment, a valve tilting device is provided, which is adapted to tilt the valve towards the discharge port and direct the flow of water to the discharge port. Such a valve tilting device ensures a good flow and flow of water flow to the discharge port, limiting turbulence.
Le dispositif d'inclinaison de clapet peut comprendre un moyen magnétique d'inclinaison. En particulier, le moyen magnétique d'inclinaison peut être adapté pour créer un champ magnétique non uniforme, avec une force de répulsion plus faible proche de l'orifice d'évacuation et une force de répulsion plus élevée loin de l'orifice d'évacuation. Ainsi, un tel moyen magnétique d'inclinaison est robuste et fiable, et peut venir travailler en synergie avec les moyens magnétiques de rappel en position fermée et de maintien en position fermée du clapet.The valve tilt device may comprise magnetic tilt means. In particular, the magnetic tilt means may be adapted to create a non-uniform magnetic field, with a lower repulsion force near the discharge port and a higher repulsion force away from the discharge port . Thus, such a magnetic tilting means is robust and reliable, and can work in synergy with the magnetic return means in the closed position and holding in the closed position of the valve.
Dans un aspect de l'invention, le dispositif d'inclinaison est constitué par le moyen magnétique de rappel en position fermée, comprenant un troisième élément magnétique. Dans cet aspect, le troisième élément magnétique est incliné par rapport au fond du corps, et/ou décalé par rapport au deuxième élément magnétique, ou bien présente une dissymétrie de forme et/ou de magnétisme.In one aspect of the invention, the tilting device is constituted by the magnetic return means in the closed position, comprising a third magnetic element. In this aspect, the third magnetic element is inclined relative to the bottom of the body, and / or offset relative to the second magnetic element, or has an asymmetry of shape and / or magnetism.

Le dispositif d'évacuation des eaux 1 peut en particulier être intégré dans un système de vidage de douche, avec receveurs standards ou extra plats, ou pour le domaine des caniveaux et receveurs dits « à l'italienne »The
Le dispositif d'évacuation des eaux 1 comprend un corps 10, creux, avec un fond 11, une paroi périphérique 13, un orifice d'évacuation 12, autrement appelé ouverture d'évacuation, qui peut être rattaché à un raccord vers une canalisation ou une tubulure d'évacuation, et une ouverture supérieure14 qui définit ainsi une ouverture d'amenée d'eau.The
Le corps est de préférence en matière plastique, par exemple en polyéthylène, polypropylène, PVC.The body is preferably made of plastic, for example polyethylene, polypropylene or PVC.
L'orifice d'évacuation 12 illustré est latéral. Cet exemple n'est pas limitatif et l'orifice d'évacuation 12 peut être vertical, oblique ou à angle variable.The
Le dispositif 1 comprend une ouverture 14 qui définit ainsi une ouverture d'amenée d'eau. Un plateau 3 est porté par le corps 10, le plateau permettant le montage dans un receveur de douche (non représenté). Une grille 5 permet de couvrir le corps 10 et l'ouverture et le corps 10, tout en permettant le passage de l'eau dans l'ouverture d'amenée d'eau 14 du corps.The
Un dispositif anti-odeur 20, mieux vu sur les
Le contre-clapet 24 peut être solidaire du corps 10, de manière fixe ou amovible pour permettre un nettoyage ou une inspection du système ou du réseau, ou bien peut faire partie intégrante du corps.The
En position fermée, le clapet 22 est en contact étanche contre le contre-clapet 24, l'étanchéité étant assurée par des joints d'étanchéité 26 sur le pourtour du contre clapet 24 et/ou du clapet 22.In the closed position, the
Dans le mode de réalisation de
Le clapet 22 est maintenu en position fermée par un dispositif de maintien 30 en position fermée. Dans l'exemple illustré sur les
Dans le mode de réalisation illustré, le premier élément magnétique 32 est positionné sensiblement au centre du clapet 22, et le deuxième élément magnétique 34 est positionné sur le contre clapet 24. Autrement, le deuxième élément magnétique 34 peut être positionné sur le corps 10.In the illustrated embodiment, the first
L'homme du métier comprendra que lorsque le dispositif d'évacuation des eaux 1 est alimenté en eau par la douche, baignoire ou autre, le poids de l'eau exerce sur le clapet 22 un effort inverse à celui des éléments magnétiques 32, 34, jusqu'à être supérieur à la force d'attraction magnétique des premier et deuxième éléments magnétiques 32, 34. Ceci amène le clapet 22 à se déplacer vers le fond, ouvrant ainsi l'ouverture d'amenée d'eau 14 et permettant d'évacuer l'eau vers l'orifice d'évacuation 12.Those skilled in the art will understand that when the
Afin d'éviter soit que le clapet 22 ne descende au-delà du champ magnétique du deuxième élément magnétique 34, et ne tombe ainsi au fond du corps 11, soit que le clapet 22 n'arrive pas à revenir en position de fermeture suite à un espacement trop important, un système de rappel en position fermée du clapet 22 est prévu. Le système de rappel permet d'amorcer le mouvement de fermeture du clapet mobile 22, une fois la pression sur le clapet exercé par l'eau réduite.In order to prevent either the
Dans l'exemple illustré sur les
Ainsi, les interactions combinées du deuxième élément magnétique 34, en attraction, et du troisième élément magnétique 36, en répulsion, avec le premier élément magnétique 32, mobile, évite au clapet 22 de ne descendre trop bas ou de rester immobilisé par rapport à sa position fermée et de tomber au fond du dispositif d'évacuation des eaux par exemple. L'ouverture du clapet 22 est également optimisée car le clapet 22 ne risque pas de rester en position ouverte grâce à au troisième élément magnétique 36, inférieur, qui le repousse pour lui permettre de « raccrocher » le magnétisme du deuxième élément magnétique 34, supérieur.Thus, the combined interactions of the second
L'utilisation d'éléments magnétiques permet avantageusement de s'affranchir de tout vieillissement mécanique dépendant des composants du dispositif d'évacuation des eaux (frottement, perte de raideur, déformation sous contrainte). De même, les éléments magnétiques permettent un fonctionnement même en cas d'encrassement du système.The use of magnetic elements advantageously makes it possible to overcome any mechanical aging that depends on the components of the water evacuation device (friction, loss of stiffness, deformation under stress). Similarly, the magnetic elements allow operation even in case of fouling of the system.
L'homme du métier comprendra que le premier élément magnétique 32, le deuxième élément magnétique 34 et le troisième élément magnétique 36 sont choisis en combinaison appropriée parmi un aimant et un élément magnétique tel qu'acier, inox magnétique (ferritique) ou autre matière dont l'aimantation est possible. Il est préférentiel d'utiliser une combinaison d'aimants disposés de sorte que les effets d'attraction et de répulsion s'additionnent.Those skilled in the art will understand that the first
Comme l'on peut le constater dans la vue de la
Un dispositif d'inclinaison 50 de clapet peut être prévu, adapté pour orienter angulairement le clapet 22, en inclinant le clapet 22 par rapport au fond du corps, en position d'ouverture, vers l'orifice d'évacuation 12.An
Dans l'exemple des
Plus précisément, le dispositif d'inclinaison 50 est adapté pour interagir en répulsion avec le premier élément magnétique 32, en engendrant un champ magnétique non uniforme, avec une force de répulsion plus faible proche de l'orifice d'évacuation 12 et une force de répulsion plus élevée loin de l'orifice d'évacuation 12.More specifically, the
Ce gradient de force magnétique permet de favoriser l'angle d'ouverture du clapet 22, par rapport au fond du corps et dans le sens de l'écoulement de l'eau vers l'orifice d'évacuation. Ainsi, le clapet 22 sera repoussé plus haut et loin du fond là où la force de répulsion est plus élevée, et sera repoussé moins haut là où la force de répulsion est plus faible, du côté de l'ouverture.This magnetic force gradient makes it possible to favor the angle of opening of the

Dans le mode de réalisation des
En fonction de la force de répulsion du dispositif d'inclinaison 50 par rapport au poids de l'eau s'écoulant sur le clapet et forçant l'ouverture de celui-ci, une amélioration de l'écoulement de l'eau vers l'orifice d'évacuation 12 peut être obtenue en position intermédiaire et en position grande ouverte, ou bien uniquement en position intermédiaire. De plus, le dispositif d'inclinaison 50 de clapet peut également améliorer l'amorçage du mouvement de fermeture, une fois que la pression exercée par l'eau est réduite le clapet prendra une position inclinée favorisant le rapprochement dans le champ d'attraction du premier élément magnétique.Depending on the repulsion force of the
L'homme du métier comprend que l'écoulement de l'eau suit deux phases. Dans la première phase, l'eau commence à venir et, lorsque le poids de l'eau est supérieur à la force d'attraction du dispositif de maintien 30 en position fermée du clapet 22, le clapet 22 s'ouvre pour permettre l'écoulement de l'eau. Lorsque le flux d'eau n'est pas abondant, l'eau s'écoule vers la sortie. Cette première phase est indépendante du troisième élément magnétique en répulsion. Dans une deuxième phase, lorsque le volume et le débit d'eau est plus important, le clapet descend plus fortement. Si le clapet reste plat, l'eau circule sur tout le pourtour du clapet, ce qui crée un flux d'eau autour de la paroi périphérique 11 qui engendre des perturbations au niveau de l'orifice d'évacuation 12 et/ou de l'ouverture d'amenée d'eau 14 et qui ralentit le débit d'évacuation. Ainsi, le dispositif d'inclinaison 50 permet d'améliorer le débit d'évacuation de l'eau.Those skilled in the art understand that the flow of water follows two phases. In the first phase, the water begins to come and, when the weight of the water is greater than the force of attraction of the holding
