Abstract

According to some embodiments, a ventilated toilet has an airflow path through an overflow tube to an air space above a water level in a tank, and an air vent path leading from the air space. In some embodiments, the air vent path includes an air duct or conduit leading to an exhaust fan. In some embodiments, the device further includes a dip tube for providing ventilation to the air space upon lowering of the water level in the tank.

Claims

exact text as granted — not AI-modified
1 . A ventilated toilet comprising: an airflow path through an overflow tube to an air space above a water level in a tank, and an air vent path leading from said air space.  
   
   
       2 . The ventilated toilet of  claim 1 , wherein said air vent path includes an air duct or conduit leading to an air removal means.  
   
   
       3 . The ventilated toilet of  claim 2 , wherein said air removal means is an exhaust fan.

       5 . The ventilated toilet of  claim 2 , wherein said air removal means is encased in about a 4 inch (4″) diameter metal flexible exhaust tube.  
   
   
       6 . The ventilated toilet of  claim 2 , wherein said air removal means can be stopped and started by a control means.  
   
   
       7 . The ventilated toilet of  claim 6 , wherein said control means is a switch.  
   
   
       8 . The ventilated toilet of  claim 6 , wherein said control means is a sensor.  
   
   
       9 . The ventilated toilet of  claim 1 , wherein said overflow tube is a tube with a diameter of about 2 inches (2″).  
   
   
       10 . The ventilated toilet of  claim 1 , wherein said overflow tube is a tube with a diameter of about 1½ inches (1.5″)-2½ inches (2.5″).  
   
   
       11 . The ventilated toilet of  claim 1 , wherein said overflow tube is a tube with a diameter of about 1 inch (1″)-3 inch (3″).  
   
   
       12 . The ventilated toilet of  claim 1 , wherein said overflow tube is a tube with a diameter greater than 1 inch (1″).  
   
   
       13 . The ventilated toilet of  claim 1 , wherein said overflow tube is a tube with a diameter greater than 1½ inches (1.5″).  
   
   
       14 . The ventilated toilet of  claim 1 , wherein said overflow tube is a tube with a diameter greater than 1¾ inches (1.75″).  
   
   
       15 . The ventilated toilet of  claim 1 , wherein said overflow tube is a tube with a diameter greater than 2 inches (2″).  
   
   
       16 . The ventilated toilet of  claim 1 , wherein said overflow tube is a tube with a diameter greater than 2¼ inches (2.25″).  
   
   
       17 . The ventilated toilet of  claim 1 , wherein said overflow tube is a tube with a diameter greater than 3 inches (3″).  
   
   
       18 . The ventilated toilet of  claim 1 , wherein said ventilated toilet is retrofitted on a non-ventilated toilet.  
   
   
       19 . The ventilated toilet of  claim 1 , further including a dip tube for providing ventilation to said air space upon lowering of the water level in said tank.  
   
   
       20 . The ventilated toilet of  claim 1 , wherein said air vent path leading from said air space comprises a pipe from the tank exhaust port and a flexible exhaust tube which leads to said air removal means.  
   
   
       21 . The ventilated toilet of  claim 20 , where said pipe from the tank exhaust port and said flexible exhaust tube have a transition means to connect them.  
   
   
       22 . A method for ventilating a toilet comprising: establishing an airflow path through an overflow tube to an air space above a water level in a tank and through an air vent path leading from said air space.  
   
   
       23 . The method of  claim 22 , wherein said air vent path includes an air duct or conduit leading to an air removal means.  
   
   
       24 . The method of  claim 23 , wherein said air removal means is an exhaust fan.  
   
   
       25 . The method of  claim 23 , wherein said air removal means is a turbo vacuum motor.  
   
   
       26 . The method of  claim 23 , wherein said air removal means is encased in about a 4 inch (4″) diameter metal flexible exhaust tube.  
   
   
       27 . The method of  claim 23 , wherein said air removal means can be stopped and started by a control means.  
   
   
       28 . The method of  claim 27 , wherein said control means is a switch.  
   
   
       29 . The method of  claim 27 , wherein said control means is a sensor.  
   
   
       30 . The method of  claim 22 , wherein said overflow tube is a tube with a diameter of about 2 inches (2″).
