Abstract:
A commode filtering device for use in a commode water tank having an overflow tube operably disposed therein and communicating with a toilet bowl, and having refill device with a refill tube and float operably disposed in the water tank which includes:a housing having a first generally longitudinally disposed chamber extending inwardly from a first open surface in a bottom portion of said housing and of a size and configuration to removably receive the overflow tube and terminating into an upper interior surface portion; a second generally longitudinally disposed chamber communicating with said upper interior surface portion and terminating into a lower interior surface portion of said housing; a third generally longitudinally disposed chamber communicating with said lower interior surface portion and terminates into a second open surface in an upper portion of said housing; a fan including a rotatable hub and a plurality of fan blades radially extending therefrom and said fan is disposed in said second chamber, said fan operably disposed in said housing with said fan blades to rotate in a direction of air flow and in which to cause sufficient air flow to be drawn from said bowl through said first chamber and said second chamber and trapped from escaping back into said second chamber once entering said third chamber; an air deodorizer disposed within said third chambers in a manner to extend from said second open surface into said third generally longitudinally disposed chamber to receive air flow exiting from the overflow tube where upon exiting deodorizes the air, and wherein said second chamber includes a partial arcuate surface portion of larger size than an area in which said fan operates and wherein said fan is disposed more closely to a starting point of said partial arcuate surface portion than an exiting end point of said partial arcuate surface portion such that upon operation of said fan creates less than atmospheric pressure in said second chamber substantially causing flow of air in the direction said fan blade rotation.
