Siphon, particularly an odour trap for a urinal, a floor drain and/or a shower tray or the like

Abstract

A siphon, particularly an odour trap for a waterless urinal, a floor drain and/or a shower tray or the like, including a tubular inlet and at least one outlet, the outlet opening of which can be opened and closed to a drain that can be connected by a valve. The valve includes a valve lever mounted in an articulated manner in the region of the inlet, which has an associated valve surface, wherein the valve surface seals the outlet opening in a form-fit and/or force-fit manner.

         7 . The siphon as claimed in one of  claims 1  to  6 , characterized in that the valve surface ( 7 ) is part of a valve cover ( 9 ) which is connected to the valve lever ( 6 ). 
     
     
         8 . The siphon as claimed in one of  claims 1  to  7 , characterized in that the valve lever ( 6 ) and/or the valve cover ( 9 ) are/is acted upon by an actuating member, in particular a spring ( 22 ), a solenoid device, or a piston-cylinder arrangement, for opening and/or closing the outlet opening ( 3 ). 
     
     
         9 . The siphon as claimed in one of  claims 1  to  8 , characterized in that the valve cover ( 9 ) is coupled to a free end of the valve lever ( 6 ) preferably via a joint in such a manner that said valve cover extends on both sides of the joint between the valve lever ( 6 ) and the siphon and also beyond the free end of the valve lever ( 6 ), or on one side of the joint between the valve lever ( 6 ) and the siphon. 
     
     
         10 . The siphon as claimed in one of  claims 1  to  9 , characterized in that the joint between the siphon and the valve lever ( 6 ) and/or between the valve lever ( 6 ) and the valve plate ( 7 ) is designed as a hinge joint ( 5 ,  8 ). 
     
     
         11 . The siphon as claimed in one of  claims 1  to  10 , characterized in that at least one spacer cam ( 15 ) which is effective for closing the outlet opening ( 3 ) is arranged between the valve lever ( 6 ) and the valve cover ( 9 ). 
     
     
         12 . The siphon as claimed in one of  claims 1  to  11 , characterized in that the joint in the region of the inlet ( 1 ) is formed on a clip ( 16 ) which acts, in particular in a force-fitting manner, on the siphon, wherein the valve lever ( 6 ) and the valve flap ( 9 ) extend on the outer side of the siphon. 
     
     
         13 . The siphon as claimed in one of  claims 1  to  12 , characterized in that the sealing surface ( 11 ) is curved convexly in its longitudinal extent. 
     
     
         14 . The siphon as claimed in one of  claims 1  to  13 , characterized in that the inlet ( 1 ) is formed by an end-side or lateral opening in a pipe ( 18 ), the further profile of which has at least one bend ( 19 ), the free end of which forms the outlet opening ( 3 ) which is preferably surrounded by the sealing surface ( 11 ). 
     
     
         15 . The siphon as claimed in one of  claims 1  to  14 , characterized in that the pipe ( 18 ) has a Y-shaped profile. 
     
     
         16 . The siphon as claimed in one of  claims 1  to  15 , characterized in that the inlet ( 1 ) is formed by an end-side opening in a pipe, the opposite end side of which, from which a cone or a pyramid extends into the interior of the pipe, is closed, wherein at least one outlet opening ( 3 ) is formed on the circumferential side in the region of the closed end side.
