Method for Air Removal from a Water-Closet Bowl and a Device for air removal from a water-closet bowl

Abstract

A method for air removal from a water-closet bowl consisting in the directing of the air from the water-closet bowl to a vertical ventilation duct where partial vacuum is generated under any weather conditions A device for air removal from a water-closet bowl whose toilet seat ( 4 ) has a passage ( 8 ) with slots ( 10 ) in its internal wall, and moreover two coaxial flange tubes ( 5 ) are connected to the said passage ( 8 ), upon which a seat cover ( 3 ) and a toilet seat ( 4 ) are mounted pivotally, and one of the said flange tubes ( 5 ) is connected to one end of a piping ( 11 ), and the other end of the said piping ( 11 ) is coupled with the vertical ventilation duct ( 1 ) which is laid out along the waste riser ( 24 ) and the outlets of the duct branches are in the vicinity of the water-closet bowl ( 2 ), and furthermore a cowl ( 12 ) with a head (13) which terminates with a broadening cone and an air louver ( 14 ) is installed upon the roof outlet of the vertical ventilation duct ( 1 ).

1 . A method of air removal from a water-closet bowl to the atmosphere through a vertical ventilation pipe, characterized in that gravitational suction generated in vertical ventilation pipe ( 1 ) is enhanced by aerodynamic suction generated in a cowl ( 12 ) fitted out with a head ( 13 ) adjusting its position relatively to the direction of flow of external air by means of a guide wing and preventing from the air reversal flow by means of an air louver ( 14 ). 
   
   
       2 . The method according to  claim 1 , where vertical ventilation pipe ( 1 ) is placed along a waste riser ( 24 ). 
   
   
       3 . The method according to  claim 2 , where vertical ventilation pipe ( 1 ) is to be placed in newly constructed building. 
   
   
       4 . The method according to  claim 1 , where vertical ventilation pipe ( 1 ) is placed in a ventilation duct ( 21 ), and where the upper end of a piping ( 11 ) passes through a ventilation grille ( 20 ) of the ventilation duct ( 21 ), and the upper end of vertical ventilation pipe ( 1 ) is installed upon the outlet of the ventilation duct ( 21 ) by means of a support ( 22 ) with the openings ( 23 ). 
   
   
       5 . The method according to  claim 4 , where vertical ventilation pipe ( 1 ) is to be placed in existing buildings. 
   
   
       6 . An apparatus for air removal from a water-closet bowl comprising a toilet seat with a cover and a piping joining the toilet seat to vertical ventilation pipe, characterized in that vertical ventilation pipe ( 1 ) is supplied at its upper end with the cowl ( 12 ) fitted out with the head ( 13 ) adjusting its position relatively to the direction of flow of external air by means of the guide wing and preventing from the air reversal flow by means of the air louver ( 14 ). 
   
   
       7 . The apparatus according to  claim 6 , where two separated flanged pipes ( 5 ) are coaxially installed in the rear of a toilet seat ( 4 ) and a toilet cover ( 3 ), and which are fastened to the water-closet bowl ( 2 ) thus defining an axis of rotation for the toilet seat ( 4 ) and the toilet cover ( 3 ), and which communicate at one end with a passage ( 8 ) and at the other end with the piping ( 11 ). 
   
   
       8 . The apparatus according to  claim 7 , where the passage ( 8 ) is shaped at lower side of the toilet seat ( 4 ) and is closed by a cover ( 9 ) which has side walls facing the side walls of the passage ( 8 ). 
   
   
       9 . The apparatus according to  claim 8 , where the recesses ( 10 ) in the side walls of the passage ( 8 ) and in the side walls of the cover ( 9 ) enable the air to be sucked from the interior of the water-closet bowl ( 2 ) through the passage ( 8 ), flanged pipes ( 5 ), the piping ( 11 ) and vertical ventilation pipe ( 1 ) and further exhausted through the cowl ( 12 ) fitted out with a head ( 13 ) which terminates with a broadening cone and an air louver ( 14 ). 
   
   
       10 . The apparatus according to  claim 6 , where vertical ventilation pipe ( 1 ) is placed in the ventilation duct ( 21 ), and where the upper end of the piping ( 11 ) passes through the ventilation grille ( 20 ) of the ventilation duct ( 21 ), and the upper end of vertical ventilation pipe ( 1 ) is installed upon the outlet of the ventilation duct ( 21 ) by means of the support ( 22 ) with the openings ( 23 ).
