Definitions

  • the present invention relates to an aspirating device, particularly but not exclusively useful for water-closets.
  • Another drawback is due to the fact that their delay in aspirating the odors allows the temporary diffusion of said odors even into adjacent rooms if one does not take care to keep the doors closed for some time even after the source of the odor has been removed.
  • a principal aim of the present invention is to provide an aspirating device, particularly for water-closets, that solves the above-described drawbacks of conventional devices, in particular by immediately eliminating bad odors and at the same time avoiding their even minimal dispersion in the room in which the water-closet is installed.
  • an object of the present invention is to provide an aspirating device that can be easily used by the user even automatically.
  • Another object of the present invention is to provide an aspirating device the operation whereof does not affect the comfort of the room in which it must operate.
  • Another object of the present invention is to provide an aspirating device that is absolutely safe for the user from the accident-prevention point of view.
  • Another object of the present invention is to provide an aspirating device that can be manufactured with conventional technologies, is constructively simple, and can optionally be installed in existing water-closets.
  • an aspirating device particularly for water-closets, characterized in that it comprises a tubular element that is meant to be arranged on the upper rim of the opening of the water-closet bowl, the inside portion of said tubular element being connected to the inside of said bowl by means of a plurality of suction ports formed therein, a suction manifold extending from said tubular element and being connected to a suction fan that is in turn connected for discharge to a discharge duct leading into the venting system of the hydraulic system or outside the room where said bowl is located.
  • an aspirating device particularly for water-closets, according to the invention, is generally designated by the reference numeral 10.
  • the aspirating device 10 in this case, is installed on a bowl 11 of a water-closet.
  • the aspirating device 10 comprises a tubular element 12 that in this case also acts as a ring-shaped portion on which the user sits.
  • tubular element 12 can be independent and can be installed below the actual ring-shaped portion.
  • the tubular element 12 is arranged on the upper rim of the opening 13 of the bowl 11, and its interior is connected to the inside of said bowl 11 by means of a plurality of suction ports 14 formed therein.
  • the ports 14 are formed along the internal rim of the tubular element 12 and are arranged so that they are substantially equidistant from one another; furthermore, each one has, in the operating configuration, its inlet directed substantially downwards.
  • a suction manifold 15 extends from said tubular element 12 at the rear of the bowl 11; its extension axis is substantially perpendicular to the front-rear axis of said bowl 11.
  • the suction manifold 15 is articulated hermetically to the body 16 for containing a suction fan 17.
  • the hermetic articulation of the suction manifold 15 to the body 16 allows to overturn the tubular element 12 about a rotation axis lying transversely to the front-rear axis of the bowl 11.
  • the hermetic articulation between the suction manifold 15 and the body 16 occurs by means of respective edges 18 and 19 that are folded back and shaped complementarily with respect to each other.
  • a filter 20 is installed in the body 16, upstream of the suction fan 17.
  • the body 16 extends, in this case monolithically, downstream of the suction fan 17 so as to form a discharge duct 21 that leads into the venting system of the hydraulic system, not shown in the figures, or outside the room, also not shown in the figures, where said fan is located.
  • the aspirating device 10 comprises an automatic and/or manual switch, not shown in the figures, for activating and deactivating the suction fan 17; said switch can be activated, merely by way of example, when the user sits down or switches the light on.
  • a timer of a per se known type for extending the activation of the suction fan 17, also not shown in the figures, is associated in this case with said switch.
  • the aspirating device 10 Downstream of the suction fan 17, the aspirating device 10 comprises a check valve, not shown in the figures, preventing bad odors from being again released in any way into the room.
  • the discharge duct 21 can be of the in-conduit type or an external duct; the latter case is the one shown in the accompanying drawings.
  • the aspirating device according to the invention solves the problem of the immediate elimination of bad odors at the source, being activated immediately in a space that is much smaller than the room where it is installed, since the aspiration air volume is substantially the one delimited by the bowl and by the user.
  • the tubular element can be provided independently and arranged below the actual ring-shaped portion and can thus be installed even in existing water-closets.
  • the materials and the dimensions may be any according to the requirements.
