Abstract: A ventilation system is provided including a blower assembly mounted within the air space in the upper portion of a toilet flush tank, which air space is communicated with the upper and interior portion of the associated toilet bowl through an overflow pipe disposed in the water tank, and the blower assembly includes an inlet opening into the air space and a air outlet with which the inlet end of conduit structure is sealingly communicated.

Abstract: A remotely operable exhaust blower is operatively associated with the upper discharge end of the vent pipe of a recreational vehicle holding tank. A vent line including an inlet end and an outlet end is provided with its outlet end opening downwardly into a closed passage which communicate the waste outlet of the toilet with the inlet of the holding tank. The inlet end of the vent line is communicated with the flushing water supply passage for the toilet bowl through the utilization of a float-type liquid flow preventing valve which allows downstream flow of odors and gases therethrough, prevents downstream flow of liquid under pressure therethrough and prevents upstream flow of gases therethrough in the absence of water pressure in the flushing water supply pipe upstream from the valve.

Abstract: A ventilation system is provided including a blower assembly mounted within the air space in the upper portion of a toilet flush tank, which air space is communicated with the upper interior portion of the associated toilet bowl through an overflow pipe disposed in the water tank, and the blower assembly includes an air inlet opening into the air space and an air outlet with which the inlet end of conduit structure is sealingly communicated. The conduit structure includes an outlet end opening into the outlet of the associated toilet bowl below the water seal thereof and the conduit structure includes a normally closed solenoid operated flow control valve serially connected therein, the blower assembly including an electric drive motor.
