Abstract

A standard fitting toilet commode made with a hardly-noticeable integrated elongated vertical auxiliary chamber located below and behind the seat. The chamber is with a plugged external top opening at the toilet bowl's rear rim behind the seat, and another internal upper side opening connecting with the commode's drain above and downstream of the water siphon. For optional conversion into a self-ventilating toilet, a compact electric fan unit is retrofitted behind the toilet seat and secured thereto at the seat anchor holes. A single intake nozzle sucks toilet bowl gases from under the rear of toilet seat, through the electric fan, and out into the auxiliary chamber's external opening through an exhaust pipe which converts the chamber into a bottle water trap. A built-in detection sensor, an electronic control unit, and a solenoid valve manage the electric fan's operation and the bottle water trap's replenishment with water.

Claims21

Dependent claims

A self-ventilating toilet bowl system, which comprises:

a) a toilet bowl made homogeneously of any suitable material and having an inner chamber and a rim;
b) means to connect said inner chamber via a toilet siphon to a flush water supply;
c) means to connect said inner chamber to a drainage system;
d) a generally vertical auxiliary elongated chamber extending below said rim to one side of said flush water duct, said auxiliary elongated chamber being open at the top, and having a second opening at its side which communicates directly into said inner chamber of said toilet bowl, above and downstream of said toilet siphon and independent of said toilet siphon, said auxiliary elongated chamber containing a supply of water having a water level which extends up to said second opening;
e) a suction air fan unit having a suction air fan is positioned to the rear of said toilet bowl, said suction air fan unit including means for communicating with said inner chamber of said toilet bowl to draw gases thereto, said suction air fan unit further having means to direct gases removed from said toilet bowl to a generally elongated tubular member which extends into said auxiliary elongated chamber and below said water level in said auxiliary elongated chamber, to thereby form a water trap;
and
f) a water supply device positioned and adapted to supply water to said water trap when said water level of said water trap falls below the bottom end of said tubular member.

a) a toilet bowl made homogeneously of any suitable material and having an inner chamber and an upper rim;
b) means to connect said inner chamber of said toilet bowl via a toilet siphon to a flush water supply;
c) means to connect said inner chamber of said toilet bowl to a drainage system;
d) a generally vertical auxiliary elongated chamber extending through said rim and to one side of said flush water duct, said auxiliary elongated chamber being open at the top, and having a second generally circular opening at its side which communicates directly into said inner chamber above and downstream of said toilet siphon and independent of said toilet siphon, said auxiliary elongated chamber containing a supply of water having a water level which extends approximately up to said second opening;
e) a suction air fan unit having a suction air fan and being positioned behind said inner chamber, said suction air fan unit including a device for communicating with said inner chamber of said toilet bowl to draw gases from said inner chamber of said toilet bowl, said suction air fan unit further having means to direct gases removed from said inner chamber of said toilet bowl, to a generally elongated tubular member which extends into said auxiliary elongated chamber and below said water level in said auxiliary chamber, to thereby form a water trap;
and
f) a water supply device positioned and adapted to supply water to said water trap when the gasses drawn from said inner chamber are directed through said water trap and into the drainage system, and said water level of said water trap falls below the bottom end of said generally elongated tubular member.
