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. The electric solenoid and drive motor are serially electrically connected for simultaneous operation and an actuating switch is included and operatively associated with the pivotally mounted seat of the toilet bowl for closing the switch only in response to a predetermined downward pressure being applied to the seat. Of course, the switch is serially connected in a circuit electrically connecting the blower drive motor and solenoid to a suitable source of electrical potential.
