Definitions

  • This invention concerns a device for preventing animals coming up through clear or golden water drain pipes through the relative outflow section of the relative sanitation services.
  • Generally clear or golden discharge water is the water from washbasins, bidets or sinks or washing machines.
  • the discharge section of the relative above-mentioned sanitation discharges generally refers to a drain or an opening at the bottom of a collection basin.
  • said drain or opening will be called the discharge outlet.
  • This water, collected in the water collection basin, is clear water, perhaps saponified to combine with greases and free of coarse or very large elements.
  • This water in the siphon therefore, effectively prevents an air link between the discharge outlet and the relative drain pipes.
  • the object of this invention is to overcome one or more of the drawbacks of the prior art.
  • a further object of this invention is to make available a device that automatically closes the outflow section.
  • Another object of this invention is to make available a device that is completely mechanical.
  • An important object of this invention is to make available a device that cannot be overcome by an animal trying to shift it.
  • Another object of this invention is to make available a device that is self-cleaning.
  • An even further object of this invention is to make available a device that is both simple and reliable.
  • a further object of this invention is to make available a device that is both inexpensive and easy to install.
  • an important object of this invention is to make available a device that can be installed without any problems on any type of discharge that has, or which could be made to have, a siphon.
  • the device of the invention is composed of a siphon, capable of keeping a certain head of water on a branch of which there is a sphere, where said sphere is capable of joining to close the discharge outlet from inside the siphon under the thrust of the water in the branch in which said sphere is present.
  • the invention is configured as a completely mechanical device, with automatic closing of the discharge outlet.
  • the water in the siphon lets the water in the basin above flow away even with slight overpressures.
  • the siphon has the truncated cone branch in which the sphere is present, both for self-cleaning and quick closing and for security against any animals that want to come up. It is appropriate that the connecting section between the two branches of the siphon is smaller than the section of the sphere.
  • the section of the discharge outlet to which the sphere connects has a wear-resistant coating, ensuring it is long-lasting.
  • the sphere is hollow and much lighter than water, thereby providing an excellent closing action with low inertia.
  • the tapered conical section has a height/diameter ratio greater than 1, and preferably greater than 1.2, and even more preferably greater than 1.5.
  • the degree of thrust of the sphere on the discharge outlet can be modified by changing the height of the discharge of the second branch, because the height of this can be regulated.
  • the device consists of a siphon 2 composed of at least two branches 3 and 4.
  • the two branches 3 and 4 of the siphon 2 re connected by a narrow hydraulic section 8.
  • the level 11 of this water 10 is set by the communicating vessels of the two branches 3 and 4 of the siphon 2.
  • Said level 11 therefore of the water 10 establishes the degree of thrust of the sphere against the discharge outlet 5, fixing the relative connection pressure.
  • a lower position of the discharge 6 provides just a sufficient closing of the discharge outlet by the sphere 9, facilitating the flowing of the water coming from the basin above without standing water.
  • a higher position of the discharge 6 provides a closing of the discharge outlet 5 with high pressure by the sphere, avoiding that it could easily disconnect following unforeseen stress.
  • the sphere 9 will block the passage, connecting with the relative discharge outlet, and preventing any animals, which have come up through the drain pipes 7 of the drainage network, and having first passed through the second branch 4 of the siphon 2 and through the narrow section 8, which have reached the first branch 3 of the siphon 2 from going beyond the discharge outlet 5 to freely reach the basin above.
  • the form of the sphere 9 also prevents any foothold for the above-mentioned animals, so they cannot clutch it and move it, which, with any action, will start to rotate, keeping its position, making any attempt to shift it by these animals absolutely futile.
  • the taper configuration of the top part of the first branch 3 of the siphon 2 with a roughly truncated cone configuration, or the like, renders this device quick and safe to operate after the shifting of the sphere 9 due to the water flowing down from the basin above.
  • the sphere without any bouncing or deviations, will quickly return to its closed position connected to the discharge outlet 5.
  • this configuration prevents animals from staying around the sphere 9, seeking to quickly overcome the flow coming down when the discharge outlet 5 is open.
  • this inclination of the walls adjacent to the discharge outlet with a height/diameter ratio greater than 1 and preferably greater than 1.2 and even more preferably greater than 1.5, will establish a cleaning and a removal of any element or animal nearby or in the vicinity of the inclined walls next to the discharge outlet 5.
  • the descent of the sphere 9 under the pressure of the discharge water coming from the basin above creates a high speed flow in the narrow section between the sphere and relative inclined surfaces of the first branch 3, self-cleaning said inclined surfaces.
  • the above-mentioned quick flow ensures any nearby animals are removed and contributes to keeping the system clean with a forceful flow crossing the surfaces close to the discharge outlet.
  • the sphere however, also following a large flow of water, cannot leave the first branch 3 of the siphon, since the narrow section 8 is smaller than the diameter of the sphere, thereby keeping it in place. When there is no flow of water, the sphere will tend to take up its position blocking the discharge outlet 5.
  • the shape and the profile of the siphon can be significantly different, compatible with the use and the function for which they are made.
  • an outflow of the connection to the drainage pipes at 90 degrees to the main body does not change the object of the invention as protected in its essence, as also a body of the siphon that has an angled configuration, with a variable angle between the positioning of the first branch 3 with respect to the second branch 4.
  • the branch 3 has an aperture of suitable dimensions for inserting the sphere 9 inside the branch itself.
  • Said aperture which can be also used for cleaning the siphon 2 is advantageously positioned at the lower part of the siphon, which can be easily opened for inspection and/or maintenance.
