Description

WC TOILET WITH VERY LOW WATER CONSUMPTION

The present invention relates to a toilet toilet with a toilet and capable of operating with a very small amount of water, and more particularly less than one liter.

The problem related to water consumption in general is recurrent, and concerns all communities and individuals, especially in countries where water is scarce or not readily available. In countries where water is available, the current trend is to save as much water as possible, not only economically but also ecologically.

In a customary manner and in a known manner, this question has been addressed by many toilets toilets manufacturers. The latter operate on the principle of flushing that releases a certain volume of water, mixed with materials, to be evacuated by a siphon.

The system for reducing water consumption, the best known, provides two modes of evacuation with two different amounts, for example 3 liters on the one hand, and 6 or 9 liters on the other hand.

Although this known system works relatively well, and has an asset of awareness, the fact remains that the consumption of water remains important in itself, and is generally much higher than the possibilities of certain installations, taking into account the local constraints. .

Moreover, for reasons of hygiene on the one hand and psychological on the other hand, it is desirable that all the materials be evacuated at one time, leaving no traces or residual materials in the bowl.

However, the global evacuation of materials is possible with a minimum amount of liquid or water, about 5 or 6 liters or 7 liters.

We must find a balance between this imperative on the one hand, and the need to save water to the maximum, on the other hand.

The present invention aims to allow the evacuation of the least disturbing possible materials, while ensuring this evacuation with an extremely reduced consumption, and more particularly with a quantity of water less than 1 liter, of the order of 1/3 of liter.

To this end, according to the invention, WC toilets of the type comprising a bowl, a water conveying means connected to the bowl and a water distribution network or a tank, a receptacle of the materials to be evacuated, connected to a downstream exhaust duct, are characterized in that the material receiving receptacle is movable between a first position where it retains the materials, and a second position allowing their evacuation.

More specifically, the receptacle is mounted to rocker.

The receptacle has a shape and volume such that it moves from its first resting position containing the materials to its discharge position as soon as the level of liquid and material in the receptacle exceeds a certain level or volume. With each use, a quantity of water of the order of less than 1 liter is poured into the receptacle, via the bowl.

For example, the amount of water for each use is of the order of half a liter, or preferably of the order of 1/3 liter.

The receptacle is designed to return to its rest position of contents content, automatically after emptying its contents.

To allow a reduced consumption of water, the bowl has a spillway allowing direct access to the water in the portion of the receptacle opposite the evacuation.

To allow a rocking movement for a capacity of the appropriate receptacle, the receptacle is provided with a counterweight on the opposite side to the evacuation.

For example, the receptacle has a substantially elongated shape, with a transverse cross section generally U-shaped, the opening is facing upwards, that is to say towards the bowl.

Specifically, the receptacle is hinged at about 1/3 of its length in the longitudinal direction, from the side opposite to the evacuation.

Preferably, the bottom of the receptacle consists of two faces forming an angle between them between 170 ° and 120 °. The water sent into the cuvette for each use is under pressure, and preferably is in the form of a thin layer of water running through the rear part and the bottom of the cuvette.

Part of the water sent into the bowl, is directed on the gutter around the upper part of the bowl, and the other part is directed in the form of a thin layer of water on the back and the bottom of the bowl towards the receptacle.

The toilet has an independent base and attached to the ground and on which rests the bowl and the receptacle toggle.

Preferably and for aesthetic reasons, the base is recessed relative to the bowl; in other words, the front of the bowl, the opposite side to the evacuation, exceeds the front of the base.

The invention will be better understood in the light of the description which follows, relating to illustrative and nonlimiting examples, with reference to the appended drawings in which:

Figure 1 is a schematic sectional view of the toilet toilet of the invention, in the position where the receptacle is at rest to contain the materials and water.

Figure 2 is a schematic sectional view of the toilet of Figure 1 wherein the receptacle is in its second rocked position, evacuation of water and materials.

With reference to FIG. 1, the toilets 1 of the invention are shown in section along a vertical longitudinal plane, in the direction of use, and corresponding to the position of the user. The toilets 1 are intended to be arranged preferably against a partition 2 and placed on the ground. The said vertical longitudinal plane is perpendicular on the one hand to the partition 2, and the ground. The longitudinal direction corresponds to the position of the user. The notions of "before" and "back" are defined relative to the user and / or the partition. The back is close to the partition and the evacuation.

The toilet 1 comprises a block or body 3 resting on a substantially parallelepiped base 4 resting on or fixed on the ground. The body 3 is hollow and comprises on the one hand a parallelepipedal base 5 having on its upper horizontal face an opening 6 in which is disposed a bowl 7 of suitable shape, and on the other hand a rear portion 8 close to the partition 2 and beyond the plane of the opening 6.

The bowl 7 has a generally hemispherical shape, the concavity is turned upwards, that is to say towards the opening 6 of the body 3 of the toilet. The bowl 7 thus has a front surface 9 and a rear surface 10, both substantially quarter-sphere. The distal edges 11 and 12 of the front 9 and rear surfaces 10 are shifted in a vertical plane (parallel to the partition 2) so as to provide an opening 13 forming discharge chute material to the front of the toilet.

In the body 3 is disposed a receptacle 14, having a generally elongated parallelepipedal shape in the longitudinal direction of the toilet, that is to say a direction perpendicular to the partition 2. The receptacle 14 has, seen in cross section ( perpendicular to the plane of FIGS. 1 and 2) a U-shape whose opening is turned upwardly, and directly above the discharge drain 13 of the bowl 7. The bottom of the receptacle 14 consists of a first front end 17 and a second back end 18 forming an angle between them between 170 ° and 120 ° preferably of the order of 130 ° forming a kind of V very open upwards, that is to say towards the bowl 7. The rear part, on the side of the partition 2, of the receptacle 14 is open.

In the rear part 8 of the body 3 is provided a conduit 19, a first end of which is connected to a nozzle 20 disposed at the upper rear part of the bowl 7, and the second end is connected to a source of water supply. pressure, such as a tank or a supply network, not shown, via a push button 21 known in itself and associated with a magnetic valve 21 A.

In addition, the rear portion of the body 3, close to the partition 2, has in the lower part a discharge hole 22 disposed opposite a discharge pipe 22 A through the partition 2.

Thus, in use, the materials on the one hand and the water coming from the nozzle 20 on the other hand, collected by the bowl 7, fall from the latter through the spillway opening 13 of the bowl, in the receptacle 14.

The receptacle 14 rests on the bottom 15 of the body 3 and is mounted to rock on a pivot 16 located substantially one third of the length of the receptacle. Thus, the receptacle 14 can tilt in a longitudinal vertical plane (perpendicular to the partition 2) on the transverse pivot 16, between two positions.

In its first position, shown in Figure 1, the receptacle 14 bears against the bottom 15 of the body 3 by the pivot 16, and by a part of the bottom before 17 substantially horizontal; thus, in this position, the materials and the water are retained in the receptacle 14 taking into account the concavity defined by the angle between the two front and rear bottoms 17 and 18 of the receptacle 14.

In its second position, shown in Figure 2, the receptacle 14 has tilted about the pivot 16 and then bears against the bottom 15 of the body 3 by the pivot 16, and its rear bottom 18. In this position called evacuation, the contents of the receptacle 14, that is to say the materials and the water, flow from the receptacle through the open rear portion 23 of the receptacle 14, and through the discharge opening 21 of the body 3 towards the exhaust duct 22.

The evacuation of the materials and the water contained in the receptacle 14 is carried out by gravity because, in the second so-called evacuation position of the latter, the front bottom 17 of the receptacle is inclined with respect to the rear base 18 then substantially horizontal.

A counterweight 24 is disposed in the front portion of the receptacle 14.

The operation of the device is as follows.

In use, the materials fall from the bowl into the receiver 14. The user then presses the push button 21 which causes a water supply under pressure, through the nozzle 20, in the bowl 7, under the form of a thin film or water strip on the rear wall 10 of the bowl, in order to rinse it. The amount of water thus supplied is of the order of one liter, and preferably less than one liter and for example of the order of 1/2 or 1/3 of a liter. The materials and the water fall through the spillway 13 of the bowl into the receptacle 14 which is in its rest position shown in Figure 1, where the receptacle 14 rests on the pivot 16 and the front bottom wall 17. The materials and water are contained in the receptacle.

As the successive uses, the receptacle is filled with materials and water, and the center of gravity of the latter moves gradually from front to back. The filling continues until the materials and water reach a threshold level, marked by a horizontal dotted line.

This level 25 and the particular shape of the receptacle 14 make that, as soon as the materials and water reach or slightly exceed this level 25, the center of gravity of the materials is slightly beyond the vertical passing through the pivot 16. Then, the receptacle 14 tilts towards its second evacuation position shown in FIG. 2, where the receptacle 14 bears against the bottom 15 of the body 3, by the pivot 16 and its rear base 18. As indicated above, the materials then flow by gravity to drain the receptacle 14, to the exhaust duct 22.

The evacuation position, shown in Figure 2, is maintained until the complete or almost complete flow of materials and water. However, the receptacle 14 is designed (when empty) so that the mass (including the counterweight 24) located forward (the side opposite the evacuation) of the pivot 16, is greater than the rear mass. Thus, once the materials and the water evacuated, the equilibrium of the receptacle is then broken, and the mass situated in front of the pivot 16 makes the receptacle 14 swing towards its position of use and of capacity, shown in FIG. 1 , ready for new uses. The toilets of the invention work and therefore allow to evacuate materials, on the one hand with a very small amount of water, and in any case, much lower than the amount of known systems (3 to 9 liters), and d on the other hand by simple gravity and moreover automatically (the receptacle empties by tilting as soon as a certain level is reached).

The toilets of the invention also have the advantage of being easily installed. Indeed, it is sufficient to fix the base 4 on the ground, to place the body 3 on the base, and connect the conduit 19 on a water supply network or a tank.

In addition, the base 4 is designed so that its length, in the longitudinal direction, is less than the body 3, so that the latter protrudes forwardly relative to the base 4. The resulting design is d an aesthetic part, since the base is almost invisible to the user, on the one hand, and particularly convenient for cleaning or positioning the user's feet facing the bowl, on the other hand.
