Abstract: A recreational vehicle or boat toilet includes a bowl with a water ingress line to the bowl, and a flush mechanism for emptying the bowl after water from the ingress line has entered the bowl. The recreational vehicle or boat toilet also includes a ventilation apparatus including an odor vent line communicating with the water ingress line and with an exit line leading to the external environment. Additionally, a water overflow line communicates with the water ingress line, with the odor vent line and with the exit line. A vacuum apparatus communicates with the exit line such that the odor passes from the odor vent line, through the exit line and to the external environment, and such that overflow water passes through the water overflow line, through the exit line into the external environment.

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.
