ABSTRACT:
This invention relates to a ventilated toilet system for removing obnoxious odors from the toilet bowl and includes integral vent channels formed along the base and the back inside of the water tank, and a vent adapter mounted inside the passage that directs the flow of ventilating air along the vent channels to an exhaust pipe and discharges it by a remote in-line exhaust fan to the outside atmosphere. The adapter is attached to the base of the overflow flush valve pipe or, conversely, designed to be an integral part of the overflow flush value pipe, itself, and is positioned to connect the base vent channel of the water tank to the toilet water inlet chamber of the bowl for passage of ventilating air, and to connect the overflow flush valve pipe to the water inlet chamber for passage of flush water.
