Abstract

The apparatus has a siphon in which different flushing sequences are controlled by a cylindrical shaft (9) perpendicular to a vertical median plan. A mechanical obturator closes an end part of the siphon. The shaft cooperates with a float (24) that is locked during starting of the flushing. The float is released at the end of the flushing for provoking a retraction of the obturator and a closing of a rinsing circuit of a basin.

Description

2863635 1

  To meet the increasingly imperative need to save water, various inventions have appeared in the field of WC This is particularly the case of the European patent 119366 issued from the world patent WO 840 11 78 in which a hydraulic valve incorporated in the end portion of the siphon prevents any flow during the leveling up phase in the bowl.

  In this patent the valve is constituted by a cylinder which, arranged horizontally cooperates with a hydraulic spool, an auxiliary reservoir and a ball valve.

  This device has the disadvantage of extreme complexity which results in a high cost of the device and a significant risk of malfunctions.

  The present invention repeats the principle of mechanical closure of the end portion of the siphon but by means of an incomparably simpler device in which the different movements are controlled by a shaft disposed horizontally and perpendicularly to the vertical median plane of the apparatus.

  This shaft whose pivoting is controlled from the outside by the user carries arms which, with this pivoting, cause, simultaneously: a) the depression of the opening control rod of a hydraulic spool supplying the rinsing the bowl.

  b) The depression of a shutter plate sliding vertically in a sheath connected to the top of the end part of the trap.

  c) The depression of a float housed in a small auxiliary tank which with the level rise in the bowl fills together with the siphon.

  d) This float is associated with means by which it is kept in the low position during the entire water distribution phase and the means by which it is released automatically at the end thereof.

  Then going back abruptly to the surface it causes the shaft to pivot in the opposite direction which causes the closing of the flow and the raising of the shutter plate.

  The siphonic suction can then be triggered after which the auxiliary tank is drained into the bowl to reconstitute the statutory water guard.

  The invention also introduces an important advance in the rinsing device of the bowl which is carried out by multiple jets which intervene one after the other.

  Thus the different areas of the bowl are successively scanned to ensure an almost complete rinsing of said bowl.

  The invention finally relates to an embodiment of the various organs of the device and their assembly, to reduce the production cost of the assembly.

  For a good understanding of the invention it will be useful to refer to the various appended figures given by way of non-limiting examples and which are: - A side view of the apparatus in a standby situation.

  - 2 a side view of the device after engaging a flush.

  - 3 a side view of the device in the position preceding the siphonic suction.

  - 4 a view from above of the device.

  - A detailed view of the siphon air exhaust valve as well as the push button controller recessed into the wall.

  On the base of the bowl (1) is fixed a siphon in four parts which are a rising branch (2) a horizontal element (3), a descending branch (4) and a horizontal terminal branch (5).

  Guided by two horizontal spans (6) and (7) symmetrical with respect to the vertical median plane (8) of the WC and in the upper rear part of it is placed a cylindrical shaft (9) It carries, directed towards inside the arms (10) and (11) whose ends are reversibly articulated with vertical rods directed downwards or the rods (12) and (13).

  The rod (12) is the central axis of a hydraulic slide (12a) of known type constituted by a fixed cylindrical body (14) in which, through the orifice (15) is introduced water under pressure.

  O-rings housed (17) and (18) are arranged on either side of (15).

  The rod (12) carries at its lower part a cylindrical piston (19) which slides inside (14) and comprises a cover (20) in the vicinity of which is formed an opening (21).

  The assembly is arranged so that the lowering of the rod (12) makes the opening (21) in correspondence with the orifice (15) which opens the water flowing through a conduit (22). ) which, connected to the base (14) feeds a hydraulic distributor (23).

  The rod (13) carries, fixed on its lower end, a float (24) which is housed inside a reservoir (25) which, via a conduit (26) connected to its bottom (27) communicates with the lower part of the bowl.

  By a bar (28) the rod (13) is connected to another rod (29), which at its lower end carries a rectangular plate (30) which slides vertically inside a blind shaft (31) whose open bottom portion (32) is connected to the top of the portion (5) in the vicinity of (4) while its cover (33) is sealed through the rod (29).

  Inside the hydraulic distributor (23) slides a rectangular plate (34) which bears against one of the vertical planar faces of (23) is the face (35).

  The plate (34) has in its middle part a hole (36) which, in waiting situation of the W.C. is in front of an identical hole (37a) formed 45 in (35).

  2863635 3 Just above (37a) are formed in (35) several identical holes in two in the case of the figures namely the holes (37b) and (37c).

  On the outside of (35) and in correspondence with the holes (37) are connected the ducts (38a), (38b) and (38c) whose ends open at different points (39a), (39b) and (39c) of the peripheral upper part of the bowl.

  These ends are arranged in such a way that the jets issuing from them sweep gravely the corresponding zone of said bowl.

  On the lower part of the plate (34) is fixed a vertical rod (40) which crosses the bottom (41) of (23) sealingly and carries, fixed on its lower end, a float (42) which is housed in the tank (25).

  The added weight of (34), (40) and (42) is set so that when the pressure becomes zero in (23) this assembly, by gravity, falls to the bottom of the tank which was its position initial.

  On a fixed horizontal axis (67) perpendicular to the plane (8) and placed above the tank (25), pivots a rod (43) which, when in the vertical position, is at its lower end (44). ) in contact with the upper horizontal face (45) of the float (24).

  On this rod (43) is fixed a bracket (46) whose one branch is the branch (47) is perpendicular to (43) while the other, (48), directed downwards, is parallel thereto.

  The assembly is arranged so that when the branch (48) is in the vertical position its end (49) is at the level coinciding with that of the final rinsing phase of the bowl.

  On one of the ends of the shaft (9) against one of the side walls of the W.0 and at the end thereof, is fixed a handle (50) which allows the user to engage a hunt by rotating the shaft (9).

  This shaft can also be pivoted by a device in which an arm (51) fixed on it in a semi-horizontal position and directed towards the rear articulates with a bar (52) guided vertically inside a groove. (53) formed in the wall (54).

  In its upper part the bar (52) carries a rack (55) which meshes with a vertical pinion (56) itself rotated by a horizontal rack (57) on the outer end of which is fixed the push button (58). ).

  When the latter is pressed, the pinion (58) is rotated in the direction of the arrow (59), which pushes the bar (52) upwards and pivots the shaft (9) in the direction of the arrow (60).

  In order to prevent the untimely fallout by its weight of the assembly 40 formed by the float (24) and the plate (30), the shaft (9) is provided with a return spring, for example of the spiral type ( 61).

  To allow the evacuation of the air originally contained in the siphon, the portion (3) comprises, at its upper part a valve (62) of any type consisting for example of a housing (63) inside which a 2863635 4 ball (64) of density less than one rises with the level to close an orifice (65) formed in the ceiling (66) of said housing.

  The operation of the device is as follows: With the engagement of a flap by pivoting the shaft (9), the float (24) sinks to the bottom of the tank (25) which allows the rod ( 43) acting in the manner of a stand, to be placed vertically and, by its lower end (44) to be in contact with the horizontal upper face (45) of the float (24).

  Solidarity of the float (24) the plate (30) is depressed with equal amplitude and closes the portion (5) of the siphon.

  At the same time the rod (12) is lowered and the pressurized water circulates in the conduit (22) to feed the distributor (23).

  It then passes through the holes (36) and (37a) to feed the conduit (38a). The water arriving in the bowl simultaneously raises the level both in the latter, in the reservoir (24) and in the siphon while the air is evacuated by the valve (62).

  During the entire duration of this phase the float (24) remains blocked by the action of the stand (43) but the float (42) is raised and with it the plate (34) which successively closes the hole (37a) to clear the hole (37b) and then close the hole to clear the hole (37c), the passage of the jet from one to the other is carried out with overlap to ensure the continuity of the flow.

  The last phase of the rinse, which corresponds to the situation where the siphon is completely filled, is also where the lower end (49) of the branch (48) is raised under the buoyancy pressure applied on the float (42). and it tilts the bracket (46) by removing the stand (43) from the face (45). The float (24) is thus released from any obstacle and can go up to the surface by causing the lifting of the plate (30) and siphonic suction. while the pivoting of the shaft (9) in the opposite direction, bringing the rod (12) back to its initial position closes the hydraulic circuit.

  Immediately afterwards, the tank (25) empties into the bowl and the float (42) drops into the bottom of the tank (25).
