Description

CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This application claims priority of provisional application No. 60 / 538,045, filed on Jan. 21, 2004.STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT [0002] Not Applicable. APPENDIX [0003] Not Applicable. BACKGROUND OF THE INVENTION [0004] 1. Field of the Invention [0005] The present invention relates generally to venting a toilet assembly, and more particularly to venting via the tank or water closet portion of the toilet assembly. [0006] 2. Related Art [0007] A typical toilet assembly is composed of a bowl, tank and lid. The bowl functions as support for a seat assembly on which a typical user sits. In a two-piece assembly the bowl also functions as a support for the tank while in a single piece design the bowl and tank are molded as one piece. The bowl contains passages under the rim for transporting water from the tank into the bowl for flushing waste and cleaning the walls of the bowl. [0008] The tank functions as supp...

Benefits of technology

[0012] This invention will also facilitate attachment of energy recovery systems in which the exhausted interior air is channeled through a heat exchanger where the energy from the exhausted air is recovered by the incoming air from outside. The energy exchange also facilitates indoor air quality improvement and circulation. This feature is important because most modern buildings and houses are built more tightly to promote energy efficiency. It is intended to accomplish this by providing a tank with a venting hole at the base of the tank or on the back wall of the tank. It is also the intention of this invention that the means for collecting and channeling the odors out of the tank provide the option of being manufactured integral to the tank or modular assembly of odor collecting and channeling components.

[0013] Odor collecting components will be designed or assembled such that odor-collecting points will tower above the designated tank waterline or level, and above the top of the fill tube. This will prevent the exhaust system from ingesting water. Odor collecting points and components will also be located lower than the top rim of-the tank while leaving enough clearance with the lid or cover to provide free flow of air to the suction or collecting points.

[0014] This invention is intended to vent odors or fumes by providing another hole at the bottom of the tank or on the back of the tank. It is anticipated to locate the vent holes or outlets to the right of the centerline of the toilet assembly. By locating the vents to the right of the centerline of the toilet; this invention provides those skilled in the art of building or remodeling homes and other buildings with a known standard location for routing of the odor collecting lines, conduits or other plumbing based on the planned location of the toilet in the bathroom. Those skilled in the art of building or remodeling homes and other buildings will also be obligated or directed to provide space behind the wall free of internal structural reinforcement to facilitate easy installation of venting lines or conduits during or after completion of construction of the premises. The option of locating the vent hole at the bottom or back of the tank is intended to account for the difference in current and future tank styles without changing the design or profile. While the size of the vent holes may vary depending on the features and shape of the tank it is advised to be the same size as the flush valve installation hole to simplify installation components and tools.

Problems solved by technology

This means that odors will-not be allowed to fill the room before being exhausted.
