Definitions

  • the present invention refers to a discharge closure set for sanitary facilities. More in particular, the present invention refers to discharge closure set for sanitary facilities of reduced wear and easy to make, as well as a sanitary facility using the same.
  • Discharge systems for sanitary facilities such as for example sinks, wash-tubs, bidets, showers and bath tubs, generally have a closure set comprising a plug free to move between a first raised discharge opening position and a second lowered discharge closing position, and opening/closing means which operate on the plug in order to move it to one of the two such positions.
  • closure sets are generally provided with mechanical opening/closing means, such as levers, which, in order to move the plug to its opening position, come into contact with the base of the same pushing it upwards, while in closing they are moved to a non-interfering position with the base of the plug thus letting it fall due to gravity until the head of the plug closes the discharge mouth completely.
  • opening/closing means are moved manually by a user.
  • Closure sets based on mechanical actuation require special attention in use by the user in that they break easily.
  • the actuation means are generally subject to deformation and thus they can no longer guarantee sufficient raising of the plug.
  • the mechanical opening/closing means are subject to quick wear, especially the hydraulic seals which the levers have to be provided with, such elements coming constantly into contact with water.
  • the plug is moved to closing and opening position by electromagnetic means such as for example solenoids, which, when supplied with power, generate a magnetic field capable of moving an actuating core which thus comes into contact with the base of the plug and exerts mechanical force upwards with respect to the same.
  • electromagnetic means such as for example solenoids
  • the electrical parts supplying the solenoid with power and the solenoid itself are generally housed in an environment with high risks of contact with liquids, thus exposing the user to danger in case of failure or short-circuit.
  • Document JP 073171118 discloses a drainage-plug comprising a first magnet fixed to a drainage plug through a rod and a second magnet which can be displaced horizontally, wherein the two magnets have opposing facing polarities.
  • Another object of the present invention is to overcome the abovementioned drawbacks and in particular to make a discharge clousure set for sanitary facilities capable of offering high realibility over time. Another object of the present invention is to provide a discharge closure set for sanitary facilities, easy to make and at a low cost.
  • Further object of the present invention is to make a discharge closure set for sanitary facilities, which does not expose the user to any danger.
  • the discharge closure set 10 comprises a plug 11 free to move between a first raised opening position and a second lowered closing position.
  • Such plug 11 is provided with at least one portion complementary to a discharge mouth 12, which, at a closed position, cooperates with such mouth 12 closing it completely.
  • the complementary portion is provided with a gasket 14 adapted to maintain a watertight closure of the discharge mouth 12, which prevents the discharge of the water present in the sanitary facility 50 in a discharge pipe 13.
  • discharge closure set 10 is provided with opening/closing means 15 which cooperate with the plug 11 in order to move it into either the open or closed position.
  • the opening/closing means comprise an element 18 which can be moved between a first coupling position with said plug 11 and a second uncoupled position.
  • the moveable element 18 is a first permanent magnet and the plug 11 comprises a second permanent magnet 19 of the same polarity, thus generating a repulsion effect with the moveable element 18.
  • guide and stop means 20 are provided for which cooperate with the plug 11, in order to define and delimit the distance which can be covered by the same.
  • Such guide and stop means 20 cooperate with the lower portion of the plug 11 in order to provide a stop for the opening movement of the plug 11.
  • the moveable element 18 of the opening/closing means 15 is preferably connected to actuation means 16 outside the sanitary facility 50 and arranged such that they can be activated by a user.
  • the external actuation means 16 operate on the moveable element 18 to control its movement through suitable motion transmission means 17, wherein a rigid rod connected to a lever 21 rotating around a pin 22 and moving the moveable element 18 between the two positions.
  • the moveable element 18 is positioned outside the discharge pipe 13; therefore, the motion transmission means 17 do not have to come into contact with water.
  • the plug 11 of the discharge closure set according to the present invention and the discharge mouth 12 are housed in a quick-mounting water discharge group 210.
  • Such water discharge group 210 comprises a first element 212 which can be pre-coupled in a non-removable manner with the sanitary facility 50, and a second element 213 which can be rapidly coupled with the first 212 during the assembly step of the same group 210, for example during the installation of a sanitary facility 50.
  • the first element 212 of the discharge group is mushroom-shaped and can be applied in a hole 54 present in a lower portion of the sanitary facility 50.
  • the first element 212 comprises a head portion 215 which, when said first element is pre-assembled onto the sanitary facility 50, cooperates with the internal wall of such sanitary facility 50, substantially completely covering the hole 54 provided for at the base of the same, and extending beyond it for a short section.
  • the first element 212 also comprises a tubular portion 216 for coupling with the hole 54 which extends from the head portion 215 up to beyond the lower wall of the sanitary facility 50 through the hole 54.
  • a lower closure ring 240 is provided for, preferably equipped with interlocking teeth 230, which laterally operates against the tubular portion 216 and on the upper side against the external lower wall of the sanitary facility 50.
  • Such lower closure ring 240 can be advantageously screwed onto a lower portion of the tubular portion 216 projecting below the sanitary facility 50.
  • complementary threaded surfaces 246, 247 are provided for both on the external tubular portion 216 and on the internal surface of the lower closure ring 240.
  • portions 215 and 216 of the mushroom-shaped element 212 can be integrally made, as previously described, or they can be two separate elements such as a conical body 216 equipped with a lower threaded end 246, and an upper covering cap 215.
  • the second element 213 of the water discharge group 210 can be coupled with the first element 212 below the sanitary facility 50.
  • such second element 213 is a box-shaped element internally defining two compartments selectively communicating through the discharge mouth 12.
  • the second element 213 comprises a first upper opening 217 and at least a second opening 218 towards the water discharge pipe 13, the latter positioned downstream of the discharge mouth 12 cooperating with the plug 11.
  • the first upper opening 217 is stably coupled with the lower closure ring 240 constrained to the tubular portion 216 of the first element 212 projecting below the wall of the sanitary facility 50.
  • the bond between the two elements, first 212 and second 213, of the discharge group 210 is such that the lower part of the first element 212 is directed towards the inside of the second element 213 itself.
  • the first upper opening 217 and the related contact portion of the lower closure ring 240 can be snap-coupled due to the presence of an annular projection 241 equipped with a tooth-shaped end 220 capable of interlocking with the annular seat 245 made on the external surface of the opening 217.
  • a water passage is formed starting from the first element 212 through to the second element 213 and, more generally, from inside the sanitary facility 50 to the discharge pipe 13.
  • Figure 1 shows a bath tub 50 provided with the discharge closure set 10 for sanitary facilities according to the present invention as well as a quick-mounting water discharge 210.
  • such discharge closure set 10 and/or quick-mounting water discharge group 210 can also be employed for sinks, wash-tubs, showers, bidets or other similar sanitary facilities.
  • sanitary facilities 50 are also preferably provided with a filling limiting device 110 which comprises a first pipe 111 connectable at a first end 112 thereof to the base of a filling tank 51 of a sanitary facility 50 for example through the discharge group 210, and connected at a second end 113 thereof to a second pipe 114 for water drainage.
  • the first pipe 111 is shaped in a manner such that its second end 113 is positioned at a higher elevation with respect to its first end 112.
  • the second pipe 114 comprises a first end 115 connected to the second end 113 of the first pipe 111 and a second end 116 positioned at a lower elevation than the first end 112 of the first pipe 111.
  • the second pipe 114 is connected at its second end 116 to the discharge pipe 13 of the sanitary facility 50, for example through the discharge group 210.
  • the discharge group 210 is additionally provided with a third 233 and a fourth 234 opening respectively connected to the first 111 and to the second 114 pipe of the filling limiting device 110.
  • a vent pipe 117 towards the environment is provided for.
  • a vent control valve 119 is arranged and provided with a membrane 120 which allows exit and/or entry of air into the filling limiting device 110.
  • the membrane has at least one coupling seat with the end 118 of the vent pipe 117 open and is made of elastically deformable material in order to selectively make a sealed coupling with such end.
  • the membrane is provided with a centrally-arranged cross-shaped cut and it is advantageously of negligible weight.
  • vent control valve 119 faces a wall of the sanitary facility 50 at the external actuation means 16. In such a manner, such valve 119 is concealed from sight and protected against clogging due to accumulation of dirt or any other sediment material.
  • the moveable element 18 is brought by the motion transmission means 17 to a distal position with respect to the plug 11 so that there is substantially no coupling between the permanent magnet 19 provided for on the plug and the moveable element 18 itself.
  • the plug 11 When in closure position, the plug 11 is at least partially inserted in the discharge mouth 12 and completely closes it in a substantially watertight manner.
  • the discharge mouth section 12 is preferably frustoconically shaped, with the larger base turned upwards, like the section of the plug portion complementary to the same. In such a manner, on one hand, greater interference and thus sealing between the plug 11 and such mouth 12 is ensured, while on the other hand, the mouth 12 acts as a stop for the closing movement of the plug 11.
  • the filling tank 51 collects water up to a first maximum filling level delimited by the elevation at which the first and the second pipe 111, 114 of the filling limiting device are joined. The water reaches such level also in the first pipe 111 of the filling limiting device 110. Once such level has been reached, the excess water tends to flow, pushed by the weight of the water present in the filling tank 51, from the first pipe 111 of the filling limiting device 110 to the second pipe 114 of the same, thus flowing towards the discharge pipe 13, connected downstream of the second pipe 114 through the discharge group 210.
  • the filling tank 51 When the filling tank 51 reaches a second filling level, in which the pipes 111, 114 are completely emptied of air the communicating vessels effect is triggered and the filling tank 51 tends to empty up at the maximum flow rate.
  • the filling tank 51 continues emptying until a third predetermined filling level is reached, in which a depression is created in the pipes 111, 114 such to induce the membrane 120 to open its cross-shaped cut. This leads to a small inflow of air which compensates for the depression created in the pipes 111, 114 and disables the communicating vessels effect.
  • the plug 11 rises, guided by the guide and stop means 20, until it interferes with the same, thus leaving the discharge mouth 12 at least partially open. Hence the water can flow directly into the discharge pipe 13.
  • the discharge closure set for sanitary facilities has a simple structure which can be compared with the currently known closure sets using mechanical opening/closing means, thus also maintaining the costs of production low.
  • the discharge closure set for sanitary facilities according to the present invention does not require electrical power supply which could, in case of failure, expose the user to danger.
