Definitions

  • the invention relates to a toilet flushing opening device.
  • the float and the element are generally immobilized by means of a locking mechanism and when they are released, they are able to transmit their upward movement to the valve to cause the opening of said valve.
  • the locking mechanism can easily be made of a permanent magnet cooperating with a metal plate.
  • the magnetic field generated by the permanent magnet can easily be canceled by a solenoid or electromagnet operating at low voltage and autonomously, in order to cause the unlocking of the element provided with the float and therefore the valve.
  • This configuration makes it possible, in particular, to provide automatically controlled flushing which, when the user leaves the toilet, automatically triggers the actuation of the tank opening element in order to cause the evacuation of the water towards the tank. from the toilet bowl.
  • the invention overcomes this disadvantage by proposing an improvement of a device of the type described above allowing partial emptying of the tank.
  • the element is locked in a determined position of its upstroke and the permanent magnet is dimensioned so as to cause magnetic attraction to close the valve before the water is fully drained.
  • the invention proposes a toilet flushing opening device of the type previously described, characterized in that it comprises a retractable transverse stop finger, which may be selectively interposed with the right to the rod to limit the stroke of the rod to a determined portion of its maximum stroke, to limit the rise of the element to an intermediate position of opening of the tank in which the float emerges only partially in urging the element to open the valve, and from which the element returns to its closed position when the combined efforts of the weight of the element and the rod, biased to its locking position by the magnet permanent, overcome the effect of buoyancy on float, to evacuate only a portion of the water from the tank to the toilet bowl.
  • a retractable transverse stop finger which may be selectively interposed with the right to the rod to limit the stroke of the rod to a determined portion of its maximum stroke, to limit the rise of the element to an intermediate position of opening of the tank in which the float emerges only partially in urging the element to open the valve, and from which the element returns to its closed position when the combined efforts of the weight of the element and
  • the invention also relates to a control method of a device of the type described above.
  • This method comprises a step of evacuating all the water from the reservoir, during which a short electrical pulse is sent into the first solenoid.
  • this process comprises a step of evacuating part of the water from the reservoir, during which feeds the second solenoid and then sends a brief electrical pulse into the first solenoid.
  • the device 10 comprises a water tank 12 which is fed by a tap (not shown) which is connected to a water distribution network.
  • this valve is likely to be open to cause the filling of the tank 12 when the water level falls below a lower limit "B" determined.
  • the faucet is meant to close automatically when the water level reaches an upper limit "A”.
  • the reservoir 12 comprises a lower discharge orifice 14 and a vertical movable discharge valve 15 which is associated with this orifice 14.
  • valve 15 is likely to occupy a closed down position, which has been shown in FIG. figure 1 , to retain the water inside the tank 12 or a high open position, which has been shown in FIG. figure 3 , to evacuate the water to a bowl (not shown) of the toilet.
  • the device 10 comprises an element 16, integral with the valve 15 and having a float 18, which is able to urge the valve 15 to its open position of the figure 3 under the well-known effect of Archimedes' thrust.
  • the float 18 therefore exerts a lifting force of the element 16, caused by the buoyancy of Archimedes, since at least a determined fraction of the float 18 is immersed.
  • an upper bearing surface 26 of said member 16 is capable of being selectively locked or unlocked by a free lower end 20 of a vertical locking rod 22, substantially coaxial with the element 16, one end of which free upper includes a metal plate 34.
  • the upper end 24 of the rod 22 may in particular be threaded and pass through the metal plate 34 to which it is fixed by a nut.
  • the rod 22 can occupy a locking position, represented in FIG. figure 1 , wherein an upper face 32 of a permanent magnet 28 secured to the reservoir, arranged facing the metal plate 34 of the rod 22, holds the metal plate 34 under the influence of its permanent magnetic field to maintain the rod 22 blocked in contact with the upper bearing surface 26 of the element 16, in order to immobilize said element 16.
  • the permanent magnet 28 thus forms a "magnetic suction cup" capable of holding the rod 22.
  • the permanent magnet 28 is traversed by a vertical section 30 of the rod 22.
  • the vertical section 30 of the rod 22 can occupy any configuration close to the permanent lover without being limited in any way by the configuration that has only been described here as an example.
  • the rod 22 can also occupy an unlocking position shown in FIGS. figures 2 and 3 , in which a first solenoid 38, arranged near the permanent magnet 28, is electrically controlled to oppose a temporary field to the magnetic field created by the permanent magnet 28 and thus release the metal plate 34 of the rod which is thus susceptible to leave its contact with the upper face 32 of the permanent magnet 28, thus releasing the element 16.
  • the movable rod 22 is movable between these two positions.
  • the element 16 can occupy a lower position for closing the tank 12 full, in which the level of the water contained in the reservoir corresponds substantially to the line "A" of the figure 1 .
  • This position is associated with the locking of the element 16 by the rod 22 against the effect of the buoyancy force exerted on the float 18, and allows said element 16 to close the valve 15.
  • the element 16 can occupy an upper opening position of the reservoir 12, associated with the unlocking position of the element 16 by the rod 22, in which the float 22, emerging as far as possible, urges the element 16 to open. the valve 15, the rod 22 accompanying the element 16 according to a determined maximum stroke.
  • the element 16 can then occupy a lower closing position of the empty tank 12, in which the level of the water contained in the reservoir corresponds substantially to the line "B" of the figure 1 .
  • This position corresponds to a new blocking of the element 16 by the rod 22 before the filling of the reservoir 12 and therefore before the effect of the buoyancy force is exerted again on the float 18.
  • the flush opening device 10 makes it possible, in a known manner, to empty the entire contents of the tank 12 through the valve 15.
  • closure of the valve 15 may therefore occur while the water level in the reservoir 12 is intermediate between the levels represented by the lines "A" and "B" and corresponds for example to the level "C".
  • This property can be used to evacuate only a portion of the water tank 12 to the toilet bowl.
  • the invention proposes a device 10 of the type described above, characterized in that it comprises a retractable finger 62 of transverse stop, which is capable of being selectively interposed with the right of the rod 22 to limit the stroke of the rod 22 at a determined part of its maximum stroke, in order to limit the rise of the element 16 to an intermediate position of opening of the reservoir, represented in FIG. figure 2 .
  • the retractable finger 62 is moved by a second solenoid 64, between a position set back from the stroke of the metal plate 34, as shown in FIGS. figures 1 and 3 and an abutment position, shown in FIG. figure 2 in which it extends to the stroke of the metal plate 34 to block an upper face 66 of the metal plate 34.
  • the finger 62 can be cylindrical and received in a toroidal solenoid, but this configuration is obviously not limiting of the invention.
  • the device 10 comprises a support 27, integral with the reservoir 12 and having substantially a "U" shape, whose branches 29 determine a concavity 31 in which the permanent magnet 28 is received. and the first solenoid 38, of substantially cylindrical shapes.
  • the rod 22 passes through the permanent magnet 28, the first solenoid 38 and a horizontal arm 41 of the support.
  • the element 16 is substantially tubular and is coaxial with the valve 15.
  • a lower end 55 of the element 16 comprises the valve 15, and the locking rod 22 is also coaxial with the element 16.
  • This configuration is in no way limitative of the invention, but it makes it possible to limit as much as possible the radial dimensions of the device 10.
  • the reservoir 12 comprises a cage 40 which has a tubular lower portion 42, a threaded end 43 of which runs through a bore 45 of the reservoir 12 and is fixed under a lower face 47 of the reservoir by means of a nut 59. This configuration makes it possible to ensure the attachment of said lower portion 42 to the reservoir 12.
  • the lower portion 42 of the cage 40 includes the discharge orifice 14 and the element 16 is slidably mounted inside the lower portion 42 to selectively seal or discover the discharge orifice 14.
  • the cage 40 also has an inverted "U" shaped upper portion 46 whose upper arms 48 are fixed on the lower part 42.
  • the upper arms 48 receive the support 27 and have at their lower ends notches 49 for their adjustment in height in eyelets 51 of the lower part 42.
  • the second solenoid 64 is carried by one of the arms 48 of the upper portion 46 of the cage 40.
  • the arms 48 each comprise slots 25 intended to receive screws 23 for fixing the support 27 and a screw 70 for fixing the second solenoid 64.
  • This configuration makes it possible to adjust the height of the support 27 and especially to adjust the height solenoid 64, which determines the amount of water that can be partially drained.
  • the upper portion 46 may advantageously comprise a thread 57 for the attachment of electronic accessories (not shown) and a coaxial thread 39 for fixing a cover (not shown) of the reservoir.
  • the float 18 has substantially the shape of an inverted "U" whose horizontal branch 17 passes through the upper arms 48 of the upper portion 46 of the cage 40, and whose side arms 19 surround the lower portion 42 of the cage 40.
  • the float 18 is fixed at its horizontal branch 17 on the upper part 52 of the element 16, in particular by interlocking.
  • the float 18 is made of expanded polystyrene.
  • the upper portion 52 projecting from the element 16 has teeth 50 intended to promote the attachment of the float 18 on the element 16.
  • the element 16 comprises the tubular upper part 52, within which is received at least the lower end 20 of the rod 22,
  • the element 16 also comprises a tubular lower portion 54, a lower end of which receives the valve 15 associated with the discharge orifice 14.
  • the valve 15 is for example made of elastomeric material.
  • the element 16 finally comprises a transverse inner wall 58 delimiting the tubular upper portion 52 and the tubular lower portion 54, which is pierced with at least one orifice 60 forming an overflow.
  • This orifice 60 is intended to allow the passage of water in the element 16 in the direction of a central bore 56 of the valve 15.
  • This bore 56 is of a smaller diameter than the discharge orifice 14 to allow evacuation of water.
  • the transverse inner wall 58 comprises the upper bearing face 26 of the element 16 which is intended to receive the rod 22 in abutment and the orifice 60 is arranged radially with respect to the fulcrum of the rod 22.
  • the rod 22 is of a suitable length.
  • the bearing face 26 may comprise several orifices 60, angularly distributed regularly around the rod 22.
  • the tap becomes jammed in the open position, the water overflows through the upper end of the upper part 52 of the element 16 and is evacuated through the orifice 60 and the bore 56 in the toilet bowl avoiding that the reservoir 12 does not overflow.
  • a method of controlling such a device 10 may comprise a step of evacuating all the water from the reservoir, during which a brief electrical impulse is sent into the first solenoid 38 which has the effect of temporarily releasing the rod 22 and allow the raising of the element 16 and the valve 15 under the effect of the buoyancy force applied to the float 18, until the float 18 emerges maximum, as shown in figure 3 .
  • the method comprises an alternative step of evacuating a portion of the water from the reservoir, during which the second solenoid 64 is fed, then a short electrical pulse is sent into the first solenoid 38, which has the effect of releasing temporarily the rod 22 and allow only a partial rise of the element 16 and the valve 15 under the effect of the buoyancy force applied to the float 18, to the abutment position against the finger 62 as shown to the figure 2 .
  • valve 15 being open, the water level decreases in the tank 12 therefore the force exerted by the buoyancy force on the float 18 decreases gradually.
  • the attraction of the permanent magnet 28, combined with the weight of the element 16, is greater than the force exerted by the buoyancy force on the float 18, which causes the descent of the element 16 and closing the valve 15 before all the water has drained from the tank.
  • a control electronics (not shown), which is attached to the thread 57, for example, can be used to cause the release of the rod 22 and / or its blocking by sending an electrical pulse to the first solenoid 38 and feeding the second solenoid 64
  • batteries can be used to power a cascade of modules. comprising an electronic detection module which transmits information relating to the presence or absence of a user to an amplification module, which transmits this information to a central unit which determines the time of presence of the person user, and when the presence of the user is no longer detected after a certain time, triggers the sending of a pulse to a control module of the solenoid 38, which provides an electrical pulse to said solenoid 38 so that it releases the rod 22 and causes the emptying of the flush.
  • the device is selectively adjusted to completely or partially empty the tank 12.
  • this flush opening device 10 is particularly advantageous because it makes it possible to use only elements supplied with a low voltage supplied by batteries, the buoyancy being the main source of energy. energy for all efforts that consume a lot of energy.
