Ventilation system for toilet bowl

Abstract

A toilet seat ventilation system which includes a toilet bowl and a toilet seat pivotally secured to the toilet bowl. A ventilation device is interposed between the toilet bowl and the toilet seat with a built in vent. A tubing system connected to the vent is able to vent air directly into the outside or through a filter inside the room, avoiding any unpleasant odors remaining in the lavatory.

1 . A toilet seat ventilation system, comprising:
 a toilet bowl and a toilet seat pivotally secured to the toilet bowl to allow it to be selectively located thereon; and   a ventilation device interposed between the toilet bowl and the toilet seat, the ventilation device incorporating at least one built in vent which is coupled to a venting tube; and   a tubing system connected to the venting tube and configured to be able to couple into an existing venting tube for drawing air directly from the toilet bowl into the venting tube.   
     
     
         2 . The ventilation system of  claim 1 , wherein the ventilation apparatus is constructed of a resilient and compressible synthetic material and is shaped and configured to be compressed between the toilet bowl and the toilet seat in a manner which substantially seals air communication between the toilet bowl and the toilet seat. 
     
     
         3 . The ventilation system of  claim 1 , further including a venting motor configured to provide a suction force to the at least one built-in vent, and including an electrical switch which is configured to be actuated by a person sitting on the toilet seat, to turn on the venting motor. 
     
     
         4 . The ventilation system of  claim 1 , further including an odor removing filter disposed in an air path of the at least one built-in vent for removing unpleasant odors from air moving in the at least one built-in vent. 
     
     
         5 . The ventilation system of  claim 1 , wherein the toilet seat comprises a plurality of vertical spacers and wherein the ventilation apparatus comprises openings, through which the vertical spacers pass to contact the toilet bowl, whereby the weight of a person sitting on the toilet seat is substantially transferred to the toilet bowl, instead of to the ventilation apparatus. 
     
     
         6 . The ventilation system of  claim 1 , wherein the ventilation apparatus comprises throughgoing bolt openings for accommodating therein bolts by which both the toilet seat and the ventilation apparatus are secured to the toilet bowl. 
     
     
         7 . The ventilation system of  claim 1 , further including a hinge formed in the ventilation apparatus which allows the ventilation apparatus to pivotally move onto or away from the toilet bowl. 
     
     
         8 . The ventilation system of  claim 1 , wherein the at least one built-in vent comprises four sides. 
     
     
         9 . The ventilation system of  claim 1 , wherein the ventilation apparatus is constructed of a hard material, and is structurally integrated with the toilet seat. 
     
     
         10 . The ventilation system of  claim 4 , wherein the venting pipe is so located that an exhaust, distal end thereof vents into a room in which the toilet bowl is located. 
     
     
         11 . The ventilation system of  claim 10 , wherein the filter is removably mounted. 
     
     
         12 . The ventilation system of  claim 1 , wherein the tubing system is constructed of a flexible hose which is configured to be connected with the at least one built-in vent. 
     
     
         13 . A toilet seat ventilation system, comprising:
 a toilet bowl;   a ventilation apparatus configured as a toilet seat and including a pivot hinge and bolt openings that allow the ventilation apparatus to be connected mechanically to the toilet bowl and allowing the ventilation apparatus to be pivoted onto and away from a rim of the toilet bowl, said ventilation apparatus further incorporating therein at least one built-in vent which is coupled to a venting tube;   an odor filter and an suction motor coupled to the venting tube and operable to provide a suction force which causes air to flow from an interior of a toilet bowl via the filter and to be exhausted into a lavatory room in which the toilet bowl is located.   
     
     
         14 . The ventilation system of  claim 13 , wherein the activating switch is activated by the weight of the person. 
     
     
         15 . The ventilation system of  claim 13 , further including an activating switch for the suction motor, said activating switch being activated by a person sitting on the ventilation apparatus during use of the toilet bowl. 
     
     
         16 . The ventilation system of  claim 15 , wherein the suction motor is activated for a time duration which exceeds the duration that a person sits on the ventilation apparatus by a predetermined time period.
