Odour free toilet system

Abstract

An odour free toilet system comprises a vent head having an inlet which is magnetically attached to a toilet bowl. The inlet is positioned under a toilet seat and a toilet lid in between a pair of mounting assemblies for mounting the toilet seat and the toilet lid. The vent head is positioned behind the toilet seat and the toilet lid. The vent head having the inlet is out of the way of the toilet seat and the toilet lid in any position of the toilet seat and the toilet lid. The odour free toilet system further comprises an outlet fitting in the rear part of the top surface of the toilet bowl with the vent head covering the outlet fitting. A suction fan and plumbing provides air suction to the outlet fitting thereby providing air suction to the inlet close to the source of toilet odours.

1 . An odour free toilet system comprising:
 a toilet bowl having a rim, a front and a rear, the toilet bowl having a top surface in the rear of the toilet bowl, the top surface defining a pair of mounting holes for mounting a toilet seat and a toilet lid with a pair of mounting assemblies;   a plate made of a ferromagnetic material adhesively secured to the top surface of the toilet bowl in between the pair of mounting holes;   the top surface further defining an outlet hole for receiving an outlet fitting;   a vent head having an inlet further comprising at least one magnet for attaching the vent head having the inlet to the plate so that
 the vent head covers the outlet fitting and the vent head is positioned rearwardly of the toilet seat and the toilet lid; 
 the inlet is positioned forwardly between the pair of mounting assemblies under the toilet seat and the toilet lid and the inlet is set back a predetermined distance from the rim of the toilet bowl; 
 the vent head having the inlet is out of the way of the toilet seat and the toilet lid in any position of the toilet seat and the toilet lid; 
   a suction fan and plumbing for providing air suction to the outlet fitting;   
       whereby air suction is provided to the inlet. 
     
     
         2 . An odour free toilet system as defined in  claim 1  wherein the plate has a thickness ranging from about 1/16 of an inch (1.5 mm) to about ⅛ of an inch (3 mm). 
     
     
         3 . An odour free toilet system as defined in  claim 1  wherein the vent head having the inlet forms a substantially symmetrical T-shape. 
     
     
         4 . An odour free toilet system as defined in  claim 1  wherein the vent head having the inlet is made of a polymeric material. 
     
     
         5 . An odour free toilet system as defined in  claim 1  wherein the vent head has a width of about 190 mm (7.5 inches), a depth of about 39 mm (1.5 inches) and a height of about 18 mm (0.7 inches), and the inlet has width of about 86 mm (3.4 inches), a depth of about 72 mm (2.8 inches), and a height of about 9 mm (0.35 inches). 
     
     
         6 . An odour free toilet system as defined in  claim 1  wherein the vent head having the inlet further comprises a bottom gasket for sealingly engaging the bottom of the vent head having the inlet to the top surface in the rear of the toilet bowl when the vent head having the inlet is magnetically attached to the plate. 
     
     
         7 . An odour free toilet system as defined in  claim 6  wherein the bottom gasket is made of a soft polymeric material. 
     
     
         8 . An odour free toilet system as defined in  claim 1  wherein the predetermined distance for setting back the inlet from the rim of the toilet bowl ranges from about 15 mm (0.6 inches) to about 25 mm (1 inch). 
     
     
         9 . An odour free toilet system as defined in  claim 1  wherein the suction fan comprises a TT  100  vent having an input rating of about 187 cubic meter per hour (about 110 cubic feet per minute). 
     
     
         10 . An odour free toilet system as defined in  claim 1  wherein the plumbing comprises 1 inch (25.4 mm) plumbing parts. 
     
     
         11 . The vent head having the inlet further comprising at least one magnet as defined in  claim 1 . 
     
     
         12 . The toilet bowl further comprising the plate made of the ferromagnetic material and the top surface in the rear of the toilet bowl further defining the outlet hole as defined in  claim 1 .
