Air water closet

Abstract

An air water closet includes a suction channel to remove air having a foul odor from a bowl of the water closet, with the air being removed through a first compartment, extending around the rim at the top of the bowl, through holes in the bottom surface of this compartment. A rinsing channel is also provided for rinsing the bowl. Air is removed through the operation of an exhaust fan, which may be turned on and off using an electric switch, or which may be turned on whenever the proximity of a person near the water closet is detected.

       7 . The apparatus of  claim 6 , wherein the second compartment extends within the first component.  
   
   
       8 . The apparatus of  claim 1 , additionally comprising: 
 an exhaust fan; and    a tube extending within a wall to connect the exhaust tube with the exhaust fan.    
   
   
       9 . The apparatus of  claim 8 , additionally comprising: 
 a light fixture, and    an electrical switch simultaneously turning the light fixture and the exhaust fan on and off.    
   
   
       10 . The apparatus of  claim 8 , additionally comprising: 
 a proximity detector producing a proximity signal in response to the presence of a person near the water closet; and    a fan actuation circuit causing operation of the exhaust fan in response to the proximity signal.    
   
   
       11 . The apparatus of  claim 10  wherein the proximity detector includes; 
 a source in infrared energy, and    a photoelectric sensor generating a signal in response to receiving a reflection of the infrared energy.    
   
   
       12 . Apparatus for sucking air from a bowl of a water closet and for rinsing the bowl, wherein the apparatus comprises: 
 a rinsing channel extending within the water closet directing water for rinsing the bowl;    an exhaust fan;    a suction channel connected to the exhaust fan and extending within the water closet for sucking air from the bowl;    a proximity detector producing a proximity signal in response to the presence of a person near the water closet; and    a fan actuation circuit causing operation of the exhaust fan in response to the proximity signal.    
   
   
       13 . The apparatus of  claim 12 , wherein the proximity detector includes; 
 a source in infrared energy, and    a photoelectric sensor generating a signal in response to receiving a reflection of the infrared energy.    
   
   
       14 . The apparatus of  claim 12 , wherein the suction channel includes: 
 a first compartment extending around a rim above the bowl; and    a plurality of holes extending through a lower surface of the first compartment.    
   
   
       15 . The apparatus of  claim 14 , wherein the rinsing channel includes: 
 the first compartment;    the plurality of holes extending through the lower surface of the first compartment; and    an aperture within the first compartment for admitting water to the first compartment.    
   
   
       16 . The apparatus of  claim 14 , wherein 
 the rinsing channel includes the first compartment, the plurality of holes extending through the lower surface of the first compartment; a tube extending to a tee connector, and a first side of the tee connector, and    the suction channel additionally includes the tube extending to the tee connector and a second side of the tee connector, connected to the exhaust fan.    
   
   
       17 . The apparatus of  claim 14 , wherein the rinsing channel includes a tube extending through the first compartment.  
   
   
       18 . The apparatus of  claim 17 , wherein the tube extending through the first compartment is inclined to extend from an aperture at an upper surface of the first compartment to an opening at a rear surface of the bowl.  
   
   
       19 . The apparatus of  claim 14 , wherein the rinsing channel includes: 
 a second compartment extending around the rim above the bowl, adjacent the first compartment;    a plurality of holes extending through a lower surface of the second compartment; and an inlet opening within the second compartment.
