Definitions

  • the present invention relates to sanitary fixtures and more particularly a device capable of preventing partially or totally bad smells and exhalations from being spread during the use of the water-closet. It is well known that such bad smells are particularly nauseating especially for those having the need of using the lavatory straight after someone else.
  • Air-exhausters that suck air up inside the lavatories and feed it outside the same are already known.
  • a drawback of such systems for exhausting bad smells is due to the fact that bad smells remain in the restroom for a time which is certainly shorter than that necessary for the natural aeration of such room, however, longer than the typical time of use of a lavatory.
  • the next user still smells evil-smelling air or there should be no admittance for the next user until the room is fully aerated, even if it is free. In the latter case, the disposability of the lavatory is strongly reduced.
  • the object of the invention is to overcome the problems of the known air-exhausting devices by providing a device capable of suppressing or strongly reducing such particularly nauseating exhalations as soon as they give off.
  • the device includes air-exhausting means located directly near the upper opening of the lavatory pan so as to prevent the evil-smelling exhalations from being spread into the restroom.
  • a device including several intake openings located at the upper edge of the opening of the lavatory pan.
  • the device provides a lavatory pan 10 including intake openings capable of aspirating air from the inside of the pan and having their outlets above the holes for the water flushing.
  • intake openings are in a number of two: one 11 at the rear side and the second 12 at the front side. Openings 11 and 12 are connected to one or more pipes 13 running inside the upper edge of the toilet bowl up to the rear portion thereof where they are connected to an air-exhauster 14 communicating with the outside.
  • a second embodiment (Fig. 3) of the present invention provides essentially a particular cover 15 of the lavatory pan the seat 16 of which is provided with channels 17 and intake openings similar to those already described and connected as above.
  • such second embodiment allows a typical lavatory pan to be used just by replacing cover and seat and connecting the air channels to a suitable air-exhauster communicating with the outside.
  • a third embodiment shown in Fig. 4 allows a typical lavatory pan to be used by providing a "collar" 18 to be fitted by pressure or laid on the upper edge of the lavatory pan. As can be seen in Fig. 4, such collar fits with the shape of the upper edge of the lavatory pan causing its slight raising. It is self-evident that such a collar 18 is provided with inside channels connected to a plurality of intake openings along the inside periphery of the collar. Such channels are connected at the rear side to an air-exhauster that lets the nauseating air outside the restroom.
  • the exhausting pipes connecting the channels to the air-exhauster preferably of the electrical type can be passed through the holes normally provided at the rear side of the lavatory pan.
  • the air-exhauster can start operating preferably whenever the lavatory pan is used, for example by a photoelectric cell or a pressure switch, and carry on its operation as long as the restroom is used and over for a predetermined time interval controlled by a timer.
