Abstract
Ventilation system (10) for conventional flush toilet (100) generally comprises battery (20); air sweetener (30) in water tank (140) for deodorizing or scenting air(90D); air flow device (40) positioned within tank (140) including duct (50) with fan (60) therein, and electrical circuit (70) powering fan (60) when circuit (70) is activated. Duct (50) receives bowl filling hose (166) and attaches to top end (172) of bowl fill pipe (170) so as to receive air from bowl (120) System (10) may be disposed entirely within tank (140) or a fan switch (76) external tank (140) may activate fan circuit (70) and a timer circuit may deactivate fan circuit (70) a predetermined time period after activation or a float switch (80) may deactivate fan circuit (70) after flushing
Claims16
A ventilation system for use with a toilet including a bowl with an opening disposed about its rim, a tank for storing water at a storage water level, a bowl filling hose, and a bowl fill pipe interconnecting the tank with the rim opening, the bowl fill pipe having a top end including an opening in fluid communication with the rim opening, said ventilation system comprising:
- a battery mounted to the toilet for supplying electrical power;
- air sweetening means in the tank for deodorizing or scenting air,
- air flow means positioned within the tank including:
- duct means adapted for receiving the bowl filling hose and adapted for attachment to the top end of the bowl fill pipe so as to receive air from the top end opening of the bowl fill pipe and not from the tank when water is at least at the storage water level;
- and
- fan means in said duct for moving air from the bowl through the rim openings, out the fill pipe opening, and over said air sweetening means such that sweetened air is expelled from the tank;
- and
- an electrical circuit connecting said battery to said fan for powering said fan when said circuit is activated
In combination
- a toilet including:
- a bowl with an opening disposed about its rim;
- tank connected to said bowl for storing water at a storage water level, a bowl filling hose in said tank;
- and
- a bowl fill pipe interconnecting said tank with said rim opening including:
- a top end for receiving water from said bowl filling hose including:
- an opening in fluid communication with said rim opening;
- and
- a ventilation system comprising:
- a battery for supplying electrical power,
- air sweetening means in said tank for deodorizing or scenting air;
- air flow means positioned within said tank including
- duct means adapted for receiving said bowl filling hose and adapted for attachment to said top end of said bowl fill pipe so as to receive air from said top end opening of said bowl fill pipe and not from said tank when water is at least at stored water level;
- and
- fan means in said duct for moving air from said bowl through said rim openings, out said fill pipe opening, and over said air sweetening means such that sweetened air is expelled from said tank;
- and
- an electrical circuit connecting said battery to said fan for powering said fan when said circuit is activated.
