Definitions

  • the subject of this patent is an improved sanitary toilet with pressure drainage.
  • This type of toilet is very widespread, but, as already said, it requires an evacuation tube of suitable section and a large amount of water for its operation.
  • the purpose of this invention is precisely that of making a sanitary toilet whose content is expelled mechanically. Consequently, the primary goal is to make a sanitary toilet which requires a very small amount of water for its operation.
  • Another aim is also to produce a sanitary toilet which can be connected to evacuation tubes of reduced section.
  • Yet another aim is to produce a WC toilet which, with its accessories, remains particularly simple both from the construction point of view and that of the installation.
  • a non-ultimate goal is to create a sanitary toilet that can be easily inspected and cleaned if necessary.
  • an inspection plug (14) At the top of the second duct (10), adjacent to the outlet fitting (11) is an inspection plug (14).
  • Said bowl (1) has along the upper edge and in its inner part a ring-shaped conduit (15) provided with a set of holes (16) directly open towards the inside of the bowl (1); this ring-shaped duct (15) is connected posteriorly to a chamber for the water supply (17) into which ends a supply tube (18) which, in its whole is connected to the hydraulic system for supplying water with interposition of water intake means.
  • Said supply tube (18), before entering the chamber (17) has a part of the Venturi system (19) formed largely by a longitudinal internal partition (20) which shares the tube (18) in a first conduit (21) which allows the passage of water from the supply tube (18) and a second conduit (22) having an opening hole on its upper part (23).
  • the lower edge (24) of this partition (20) is anyway higher by a height h relative to the upper edge of the bowl (1).
  • the propeller (12) thus illustrated by sketches 7 and 8, has three wings (25) integral with a disc (26) raised in the shape of a cone in its central part (27).
  • the propeller (12) contained in the chamber (19) is located away from the walls (28) of the chamber (9) in order to leave a large space (29) around it. This space is necessary to allow not only the water to pass but also to be able to evacuate any content from the bowl.
  • suction duct (30) of the chamber (9) has a smaller section than that of the sending duct (31) of this same chamber (9).
  • the connector (11) is of reduced size thus allowing the evacuation tube (32) to have a small section.
  • Drawings 5 and 6 illustrate the sequence of operation of the invention.
  • the water supply takes place through an electric control, according to the arrows (33), water which accumulates at the bottom of the bowl (1) up to the level of evacuation of the siphon.
  • the motor (13) and the propeller (12) are activated, started by the water which is already in the chamber (9), sucks the contents of the bowl and expels it under pressure according to the direction of the arrow (34) through the discharge tube (32).
  • a first advantage derives from the fact that the particular combination of siphons, a first of which feeds the propeller chamber and a second, constituted by the same propeller chamber, allows the latter to be constantly filled with useful water. self-priming; moreover the first siphon stops any odors which come from the evacuation tube even if the second siphon were to empty under the pressure effect of the propeller.
  • the particular conformation of the propeller and the chamber which contains it allows an easy evacuation of the bowl without blocking or piling up.
  • the presence of one or more inspection plugs allows easy intervention in the event of crowding.
  • the sending conduit (31) is closed by an inspection plug (36).
  • a bypass duct (35) is fixed on said sending duct to convey the flow of water to the fitting (11).
