Odorless Toilet

Abstract

An apparatus for preventing objectionable odors from escaping from a toilet bowl consisting of an air-tight seal between the toilet seat and the bowl rim, an air-tight seal between the flush tank and its cover, and a blower that exhausts gases from the toilet bowl through the water apertures in the bowl rim into the flush tank and from there to a point outside the bathroom.

What is claimed:  
     
         1 . In a toilet including a bowl with a rim thereon and a seat engaging the rim, the rim having a plurality of apertures communicating with the bowl and a manifold communicating with the apertures, an improved apparatus for preventing objectionable odors from escaping from the toilet bowl, the apparatus comprising: 
 (a) an air-tight seal between the toilet seat and the bowl rim;    (b) an exhaust duct communicating with the manifold; and    (c) a blower communicating with the exhaust duct and adapted to pull gases from the bowl through the apertures, the manifold, and the exhaust duct.    
     
     
         2 . In a toilet including a bowl with a rim thereon and a seat engaging the rim, the rim having a plurality of apertures communicating with the bowl and a manifold communicating with the apertures, and also having a water tank with a cover and a flush tube communicating with the manifold, the toilet residing in a bathroom having a ceiling and a crawlspace above the ceiling and walls with joist spaces communicating with the crawlspace, and a sewer vent pipe in the walls, an improved apparatus for preventing objectionable odors from escaping from the toilet bowl, the apparatus comprising: 
 (a) an air-tight seal between the toilet seat and the bowl rim;    (b) an air-tight seal between the water tank and the cover; and    (c) a blower communicating with the flush tube and adapted to pull gases from the bowl through the apertures, the manifold, and the flush tube.    
     
     
         3 . The apparatus of  claim 2 , further comprising a vent communicating with the blower.  
     
     
         4 . The apparatus of  claim 3 , wherein the blower resides within the tank and the vent penetrates the tank.  
     
     
         5 . The apparatus of  claim 4 , wherein the blower is attached to the tank cover.  
     
     
         6 . The apparatus of  claim 3 , wherein the vent is adapted to communicate with the sewer vent pipe.  
     
     
         7 . The apparatus of  claim 3 , wherein the vent is adapted to communicate with the joist spaces.  
     
     
         8 . The apparatus of  claim 3 , wherein the vent is adapted to penetrate a wall to vent objectionable odors outside the wall.  
     
     
         9 . The apparatus of  claim 1 , wherein the tank is specially manufactured to hold the blower and to connect to the vent.  
     
     
         10 . In a toilet including a bowl with a rim thereon and a seat engaging the rim, the rim having a plurality of apertures communicating with the bowl and a manifold communicating with the apertures, the toilet residing in a bathroom having walls and a sewer vent pipe in the walls, an improved apparatus for preventing objectionable odors from escaping from the toilet bowl, the apparatus comprising: 
 (a) an air-tight seal between the toilet seat and the bowl rim;    (b) an exhaust duct communicating with the manifold; and    (c) a blower communicating with the exhaust duct and adapted to pull gases from the bowl through the apertures, the manifold, and the exhaust duct to the sewer vent pipe.    
     
     
         11 . The apparatus of  claim 10 , wherein the exhaust duct further comprises a vent pipe attached to the water feed pipe of a commercial toilet.
