Definitions
- the invention relates to a toilet flush. It will find its application in particular to equip toilets as well as vespasiennes for animals.
- a flush which constitutes a reservoir supplied from the urban low-flow water distribution network, which is provided with a drainage pipe of water to the bowl likely to carry a large momentary flow.
- the volume of the toilet flush quantifies the number of liters of water used for each maneuver.
- toilet flushes are fitted with a valve filling device controlled by a float which closes the valve when the water level inside the tank has reached a pre-fi convinceded value.
- an operating cage makes it possible to ensure the opening of a valve disposed at the bottom of the tank and which allows the flow of the contents of the tank through a pipe directly supplying the bowl.
- This closure device called buffer comprises, in addition to the valve, a float connected to the latter which maintains the opening of the latter during the entire phase of evacuation of the water contained in the tank.
- the main object of the present invention is to present a flush, the operation of which is entirely automatic.
- the flush of the present invention can be perfectly used in the WC of public places as well as the vespasiennes for animals whatever the type of bowls to be cleaned.
- the quantity of water delivered by the flush of the present invention is preset, which avoids any waste.
- the automatic operation of the present invention does not use sophisticated electronic or electrical techniques, which facilitates installation and limits its cost. 0e more, the mechanism is particularly robust which more particularly pre-destines the invention for intensive use. Other objects and advantages of the present invention will appear during the description which follows which is however given only for information and which is not intended to limit it.
- the toilet flush which will find its application in particular in the
- FIG. 1 shows diagrammatically the various components of the flush of the present invention
- FIG. 2a to 2d illustrate the different phases of the operation of the flushing automation of the present invention
- FIG. 3 illustrates a front sectional view of a preferred embodiment of flushing water of the present invention
- Figure t illustrates a side view in section of a preferred embodiment of the flush of the present invention
- Figure 5 shows schematically an embodiment of the external device for controlling the operation of the flush of the present invention.
- FIG. 6 shows diagrammatically a particular embodiment of the flush according to the invention, comprising two upstream tanks,
- FIG. 7 represents a front view of the device for opening upstream tanks according to the embodiment shown diagrammatically in FIG. 6,
- FIG. 8 represents a side view of the device for opening the upstream tanks according to the embodiment shown diagrammatically in FIG. 6.
- Figure 1 shows schematically the different parts of the toilet flush 1 of the present invention, it comprises at least two tanks 2 and 3, as well as means 4 for transferring the content of the tank (s) 2 upstream in the or the downstream tanks 3.
- the flush 1 of the present invention comprises means 5 for filling the upstream tank (s) 2 from the water distribution network 6.
- the flush 1 also includes means 7 for evacuating the content of the downstream tank (s) 3 to the bowl to be cleaned, not shown.
- the flush 1 consists of an upper upstream tank 2 and a lower downstream tank 3. Their difference in altitude means that the content of the contents of the upper tank can be transferred to the lower tank very easily. produced by simple opening of the transfer means 4.
- control device of the present invention first activates the means 4 for transferring the contents of the upstream tank 2 into the downstream tank
- FIGs 2a to 2d The different phases of the operation of the control device are illustrated in Figures 2a to 2d.
- Figure 2a we can observe the flush in the rest position in which the upper tank 2 is filled with water while the lower tank 3 is empty.
- the transfer means 4, filling 5 and evacuation 7 are then closed.
- FIG. 2c illustrates the end of the preparatory phase for the operation of the flush, that is to say when the entire content of the upstream tank 2 has poured into the downstream tank 3.
- the triggering phase flushing is illustrated in Figure 2d in which the discharge means 7 open which has the effect of emptying the content of the downstream tank 3 towards the bowl through the line ⁇ located in the extension of the discharge means 7.
- the transfer means 4 are closed and the filling means 5 open, which allows the upstream tank 2 to be filled from the ' water distribution network 6 to 'at a predetermined level.
- the two main phases of the operation of the toilet flush are on the one hand controlled when an occupant enters the room of the bowl , this is phase 2b, i.e. filling the downstream tank from the upstream tank and then the cleaning phase illustrated in FIG. 2d which occurs when the occupant leaves the premises, which ensures cleaning of the bowl before a next user comes.
- Figures 3 and 4 illustrate respectively in sectional view the front face and two sides of a preferred embodiment of the flush 1 of the present invention.
- the flush consists of an upper tank 2 and a lower tank 3 which are superimposed.
- This monobloc embodiment is particularly advantageous at the manufacturing level since the bottom 9 of the upper tank 2 acts as a cover for the lower tank 3.
- the upper tank 2 is itself closed by a cover 10.
- the upper tank 2 has a pipe 6 for connection to the water distribution network. While the lower tank 3 has in its lower part a pipe 8 which connects it to the toilet bowl to be cleaned or the like.
- Means 4 for transferring the contents of the upper tank 2 into the lower tank 3 are in the form of a buffer composed of a shutter valve 10 secured to a float 11 and a pipe 12 connecting the interior volumes of the two tanks 2 and 3.
- the shutter valve 10 has its seat 13 fixed to the bottom 9 of the tank 2.
- the valve 10 is surmounted by an operating rod 14 which allows it to be actuated.
- the conventional role of the float 11 is to keep the valve 10 clear of its seat 13 as long as the volume of water present in the upstream tank 2 has not been completely transferred into the downstream tank 3. In the closed position, the pressure of the water column acting on the upper surface of the valve is stronger than the thrust exerted by the float can therefore only play a role when the valve has been released from its seat under an external action, transmitted through of the control rod 14.
- the means of evacuation 7 of the contents of the downstream tank 3 are in a form substantially identical to that of the transfer means 4.
- the evacuation means 7 consist of a buffer which comprises a valve 14 for closing the line 8 for evacuating the liquid to the bowl.
- the shutter valve 14 has its seat 15 fixed to the bottom of the tank 3 and the valve has an upper control rod 16.
- the filling means 5 are formed by a tap 17 controlled by a float 18 placed in the upstream tank 2.
- This device operates according to the height of water present in the upstream tank 2. As the level of water rises in said tank 2, the float 18 sees its height progress and this movement is likely to cause the valve 17 to be blocked when a certain level of water has been reached.
- control rod 14 of the valve 10 is extended by a rod 19 for supporting the float 18 of the filling valve 17.
- This arrangement means that any ascending operation, therefore opening of the valve 10, causes in parallel an elevation of the float 18 and therefore a closing of the water supply tap 17.
- one of the operating characteristics of the automatic flush of the present invention is respected, that is to say that the opening of the means for transferring the content of the upstream tank to the downstream tank blocks the filling of the tank. upstream.
- FIG. 3 and 4 An embodiment of the control device 20 is illustrated in Figures 3 and 4.
- This control device is presented in the form of a linkage 20 composed of a first lever 21 articulated at its median part 22, and which comprises at one of its ends the attachment of a control rod 23 and at the other end a connection system 24 to the valve 10 for transferring the content of the upstream tank 2 into the downstream tank 3.
- the control rod is surrounded by a tube 25 passing through the bottom of the lower tank 3 and sealed so that no leakage from liquid but especially air can not be deplored at the passage of the control rod. Any traction on the control rod 23 has the consequence of tilting the first lever 21 which thus raises the valve 10 to empty the contents of the tank 2 in the tank 3 and prevent filling of the tank 2 by closing the tap 17.
- the control device 20 comprises a second lever 26 articulated in its central part 27 and which comprises at one of its ends an articulated connection 28 with the end of the first lever 21 and at the other end is connected to the rod 16 for operating the valve 14 for discharging the contents of the tank 3 towards the bowl.
- the mechanism described operates in the following manner, when the control rod 23 is pulled down, it causes the opening of the valve 10 for transferring the contents of the tank 2 into the tank 3 and the closing of the tap 17 as well as by tilting of the second lever 26 closing of the valve 14 which is applied against its seat 15. We thus witness the phase of transfer of the contents of the tanks with blocking of the filling and evacuation means.
- control rod 23 also causes the second lever 26 to tilt, which exerts traction at the level of the water evacuation valve 14 which makes it possible to supply the bowl through the pipe 8, this up to '' to completely empty the tank 3.
- the different phases of the automatic flushing operation can therefore be carried out by the control device described.
- FIG. 5 illustrates one of the possible designs for exerting the action on the control rod 23 of the flush 1 without the voluntary intervention of an operator.
- part of the ground 30 is formed of a plate 31 articulated at one of its ends 32 and which has at its other end a connection 33 with the control rod 23.
- elastic means 34 are arranged under the plate 31 so as to exert a return to the plate, the counterweight 9 must be sufficient.
- the opening of the downstream tank 2 can be delayed by adding, for example, a "door bellman" system, so that the animal has time to move away and does not happen not water the legs.
- the tank (1) can pour "under pressure” into the tank 2.
- the tank 2 pours under pressure into the bowl.
- air is trapped and is compressed in the top of each vessel, it is the role of the flaps 35, and the design of the downcomer in the form of communicating vessels. These provide an "air intake” when the tanks are empty, but block it from filling.
- the flush includes two upstream tanks 2 and 2b, the operating levers 37 and 38 of the transfer valves 10a and 10b are actuated by a rocker 39, mounted articulated relative to a fixed frame 40, delimiting the movement of a finger 41 solida of a sliding rod 42 controlling the shutter valve 7 of the downstream cu 3.
- the action of the floor 31, shown in FIG. 5, can be replaced by that of an electromagnet or of a jack ; whose operation is controlled, for example, by the operation of the lock of the access door or of this door itself, ensuring the closing of the downstream tank 3 by sliding downwards, . rod 42 ; until finger 41 is brought into contact with rocker 39 and pivoted therefrom.
- This maneuver has the effect of closing off the downstream tank 3 and releasing the water contained in one of the upstream tanks, by lifting the corresponding valve by means of the lever connecting the rod of the latter. here at one of the arms of the bascu ⁇ their.
- the rocker 39 is returned to the neutral position by means of a re-pull 47 bearing against the base of the bracket 40a, and a lug 4 disposed at the base of the rocker 39, in the axis of symmetry of the latter this.
- a re-pull 47 bearing against the base of the bracket 40a
