Abstract
An odor elimination system includes a tank adapter with passages through which odors from a toilet bowl are drawn. A fan draws the odors from the bowl through the tank adapter into a passage that includes a trap. While the fan is running, the trap is empty. A barrier moves to expose a reservoir. Water from the trap is received in the reservoir, to evacuate the trap. The barrier is moved back into the reservoir to displace water from the reservoir into the trap to block sewer odors from the drain pipe. A sipper diverts a portion of flush water to maintain the trap full.
Claims20
A method of evacuating odors from a toilet bowl comprising:
- providing a flow path from a top of a toilet bowl to a valve assembly, the valve assembly including a passage in fluid communication with the flow path and a sewer drain, the passage including a trap in fluid communication with a reservoir, the reservoir having a volume, the trap containing water and the contained water blocking flow of gases through the passage;
- evacuating water from the trap, the trap not blocking the flow of gases through the passage when water is evacuated;
- producing a pressure differential that draws odoriferous gases from the toilet bowl, through the flow path, through the passage including the trap from which water has been evacuated, and into the sewer drain;
- returning evacuated water to the trap;
- and
- discontinuing production of the pressure differential.
