Toilet ventilation apparatus

Abstract

The toilet ventilation apparatus is mounted within a toilet. The toilet ventilation apparatus is an exhaust fan system that draws air from the tank of the toilet into a piped conduit that discharges the directly into the DWV that by passes the gas trap. The toilet ventilation apparatus comprises an intake pipe, an exhaust fan, an intake valve, an exhaust hose, and a control. The exhaust fan and the control are mounted in the intake pipe. The intake valve is mounted on an end of the intake pipe. The exhaust hose connects the output of the

         6 . The ventilation device according to  claim 5   wherein the exhaust hose connects the output of the exhaust fan to the DWV;   wherein the exhaust hose is selected from the group consisting of a hose or a pipe.   
     
     
         7 . The ventilation device according to  claim 6   wherein the control is a sensor switching apparatus;   wherein the control initiates the operation of the exhaust fan.   
     
     
         8 . The ventilation device according to  claim 7   wherein the second end of the intake pipe is fitted with a first connector;   wherein the first connector is a cap that closes the second end of the intake pipe.   
     
     
         9 . The ventilation device according to  claim 8   wherein the first connector further comprises a first threaded connection;   wherein the first threaded connection installs into and seals an inlet aperture of the tank.   
     
     
         10 . The ventilation device according to  claim 9  wherein the first threaded connection is a hollow connector such that air evacuated by the exhaust fan will pass through the first threaded connection. 
     
     
         11 . The ventilation device according to  claim 10  wherein the first connector screws onto the first threaded connection. 
     
     
         12 . The ventilation device according to  claim 11   wherein the span of the center axis of the intake pipe is selected such that when the second end of the intake pipe is attached to the first threaded connection the first end of the intake pipe is above the water level.   
     
     
         13 . The ventilation device according to  claim 12  wherein the exhaust fan installs in the intake pipe such that air is pumped from the first end of the intake pipe to the second end of the intake pipe. 
     
     
         14 . The ventilation device according to  claim 13   wherein the intake valve is attached to the first end of the intake pipe;   wherein the exhaust hose attaches to the first threaded connection.   
     
     
         15 . The ventilation device according to  claim 14   wherein the control system further comprises a sensor and a switch;   wherein the sensor detects a person entering the bathroom;   wherein in response to the detection closes the switch.   
     
     
         16 . The ventilation device according to  claim 15  wherein the intake valve is an electrically operated solenoid valve. 
     
     
         17 . The ventilation device according to  claim 16  wherein the control initiates the operation of the intake valve.
