Abstract

An integral flushing system with dual discharge and toilet bowl sealing function is described, comprising a sealed cylindrical vessel (4) having a resilient circular membrane (7) at its base. Water is supplied to the vessel by a pipe (9) with a pressure regulator (6). When water accumulates in the vessel, the upper air pressure is increased and the membrane (7) acquires a part spherical shape, thus sealing the waste discharge pipe. Actuation of a mechanical valve (5) causes the accumulated water to flow under pressure and the membrane retracts, thus clearing the discharge pipe. With the device of the invention, water-saving toilet bowls of simpler manufacture are obtained.

Description

La présente invention concerne un système de chasse d'eau intégral assurant la double fonction d'évacuation et d'obturation de la cuvette de WC. The present invention relates to an integral flushing system ensuring the dual function of evacuation and closure of the toilet bowl.

Le système classique de cuvette (1),selon la figure 1, comporte un syphon (2) dans lequel stagne une masse d'eau (3) relativement importante . De plus la géométrie compliquée du conduit d'évacuation freine les déchets et nécessite une grande quantité d'eau pour refouler -ceux-ci
De nombreux systèmes d'économie d'eau limitent le débit ,mais un volume minimal de six litres environ est toujours nécessaire et conséquent b la présence du syphon
Un autre système consiste d broyer les déchets et b forcer l'évacuation par une électro-pompe .Cette solution est complexe et conteuse
Le système selon l'invention permet de supprimer le syphon et ainsi d'économiser une grande quantité d'eau
La figure 2 montre le fonctionnement d'un tel concept intégral : le dispositif est composé d'un réservoir cylindrique étanche (4) comportant d sa partie inférieure une membrane élastique (7) circulaire . Cette réserve d'eau est alimentée par uno~conduite (9) comportant un régulateur de pression (6).The conventional bowl system (1), according to FIG. 1, comprises a siphon (2) in which a relatively large body of water (3) stagnates. In addition, the complicated geometry of the evacuation pipe slows down the waste and requires a large amount of water to discharge it.
Many water saving systems limit the flow, but a minimum volume of about six liters is always necessary and therefore b the presence of the siphon
Another system consists of shredding the waste and b forcing the evacuation by an electric pump. This solution is complex and costly
The system according to the invention makes it possible to remove the siphon and thus to save a large amount of water
FIG. 2 shows the operation of such an integral concept: the device is composed of a sealed cylindrical reservoir (4) comprising at its lower part a circular elastic membrane (7). This water reserve is supplied by a uno ~ pipe (9) comprising a pressure regulator (6).

Lorsque l'eau s'accumule dans cette réserve , la pression d'air supérieure augmente et la membrane (7) se déforme selon une portion de sphère en obturant le conduit d'évacuation des déchets
Une action Pur la vanne manuelle (5) provoque l'écoulement sous pression de l'eau accumulée et la membrane se rétracte en dégageant le conduit d'évacuation
Le bloc flotteur (8) coulissant selon le tube (16) permet d'une part de faire varier le taux de compression du système et d'autre part d'obturer le conduit d'alimentation en aval du régulateur de pression .Ainsi la quantité d'eau est diminuée tandis que l'effet de chasse est augmenté
Avec ce système la quantité d'eau peut être limitée d 1,S litre ,le cycle de fonctionnement est plus efficace et plus rapide .L'absence de syphon facilite l'écoulement ,les bruits désagréables ,remous et appels d'air ,sont éliminés
L'obstruction est quasiment inexistante tandis que l'accès d la canalisation en aval de la cuvette devient possible
L'encombrement de la réserve étanche est limitée ce qui permet de l'intégrer directement & la cuvette (1) .La membrane peut être facilement réalisée en élastomère technique qui peut lui conférer une résistance mécanique extrême, une grande longévité et une parfaite etancheitó
Selon un mode de réalisation préférentiel , figure 3 ,la réserve étanche peut être placée dans la partie inférieure de la cuvette et une pédale (10) permet de déclencher la chasse.When water accumulates in this reserve, the upper air pressure increases and the membrane (7) deforms along a portion of a sphere, closing off the waste evacuation pipe.
An action for the manual valve (5) causes the pressurized flow of accumulated water and the membrane retracts by releasing the evacuation pipe
The float block (8) sliding along the tube (16) allows on the one hand to vary the compression ratio of the system and on the other hand to close the supply duct downstream of the pressure regulator. water is decreased while the flushing effect is increased
With this system the quantity of water can be limited by 1, S liters, the operating cycle is more efficient and faster. The absence of a siphon facilitates the flow, unpleasant noises, eddies and drafts are eliminated
The obstruction is almost nonexistent while access to the pipe downstream of the bowl becomes possible
The size of the waterproof reserve is limited which allows it to be integrated directly into the bowl (1). The membrane can be easily made of technical elastomer which can give it extreme mechanical resistance, great longevity and perfect sealing
According to a preferred embodiment, Figure 3, the sealed reserve can be placed in the lower part of the bowl and a pedal (10) allows to trigger the flush.

Cette disposition est particulièrement ergonomique
Selon un autre mode de réalisation ,figure 4, la réserve étanche (4) comporte un rebord inférieur arrondi (12) afin de faciliter la déformation élastique de la membrane (7).This layout is particularly ergonomic
According to another embodiment, Figure 4, the sealed reserve (4) has a rounded bottom flange (12) to facilitate the elastic deformation of the membrane (7).

L'usure et les contraintes mécaniques sont ainsi limitées ,la membrane est maintenue en position sur sa périphérie (11). Wear and mechanical stress are thus limited, the membrane is held in position on its periphery (11).

Elle peut être directement vulcanisée sur le corps ou bien maintenue par un collier de serrage
Le ressort (15) lié d'une part à la zone centrale renforcée de la membrane et d'autre part à une tige filetée (14) ,permet le réglage de la pression d'évacuation en manoeuvrant l'écrou de réglage (13) ,lequel écrou peut pivoter sur le corps de la réserve (4)
Ce nouveau concept intégral de chasse d'eau pour WC permet de simplifier la fabrication des cuvettes car le syphon est supprimé .De plus il permet une Oconommie importante d'eau
Le dispositif selon l'invention est partIculièrement destiné à la fabrication industrielle de cuvettes de WC particuliO- rement économiques du point de vue de la fabrication et de l'utilisation It can be vulcanized directly on the body or held by a clamp
The spring (15) linked on the one hand to the reinforced central zone of the membrane and on the other hand to a threaded rod (14), allows the adjustment of the discharge pressure by operating the adjustment nut (13) , which nut can pivot on the reserve body (4)
This new integral concept of toilet flushing simplifies the manufacture of bowls because the siphon is removed. In addition it allows a significant Oconommie of water
The device according to the invention is particularly intended for the industrial manufacture of WC bowls which are particularly economical from the point of view of manufacture and use.
