Drain

Abstract

The invention relates to a drainage channel for discharging a liquid comprising a duct part comprising a bottom wall and upright longitudinal side walls, wherein the duct part is provided with a discharge opening and a stench-trap situated in the duct part, wherein the stench-trap connects to the discharge opening. Preferably the discharge opening is situated in one of the upright longitudinal side walls. The drainage channel according to the invention is particularly suitable to be placed in for instance a finished floor of a wet area in a building, such as for instance a bathroom or a shower cubicle.

         4 . Drainage channel according  claim 3 , wherein the first edge and the second edge are substantially transverse to the longitudinal side walls, wherein the first edge preferably extends substantially over the full width of the bottom wall, and 
 wherein the lid preferably is detachably placed in the drainage channel.    
     
     
         5 . Drainage channel according to  claim 1 , comprising a cover means provided with inflow openings for the liquid for at least partially covering the duct part, 
 wherein the cover means preferably at least partially projects above the duct part over a distance which, preferably, substantially equals the thickness of a floor covering, such as for instance a tiled floor, surrounding the drainage channel, and    wherein the cover means preferably is detachably placed in the drainage channel.    
     
     
         6 . Drainage channel according to  claim 5 , wherein the cover means comprises a cover wall having longitudinal sides and side walls connecting to the longitudinal sides, wherein the side walls extend substantially from the cover wall in the direction of the bottom wall, and 
 wherein the cover wall and the side walls of the cover means preferably define a profile having a substantially U-shaped cross-section, wherein the side walls preferably are placed substantially perpendicular to the cover wall.    
     
     
         7 . Drainage channel according to  claim 6 , wherein the cover wall is provided with the inflow openings.  
     
     
         8 . Drainage channel according to  claim 6 , wherein the side walls of the cover means preferably at least partially rest on the bottom wall, and/or 
 wherein the side walls of the cover means at least partially abut the upright longitudinal side walls of the duct part.    
     
     
         9 . Drainage channel according to  claim 1 , wherein the bottom wall and/or the upright longitudinal side walls of the duct part, at least near the stench-trap, comprises insulation means.  
     
     
         10 . Drainage channel according to  claim 9 , wherein the duct part, at least near the stench-trap, comprises a double-walled bottom wall and/or double-walled upright longitudinal side walls, comprising spaced double walls for forming an insulation layer in between them.  
     
     
         11 . Drainage channel according to  claim 1 , wherein a first of the longitudinal side walls, at least at an end thereof facing away from the bottom wall, comprises an edge extending substantially parallel to the bottom wall and away from a second longitudinal side wall situated opposite the first longitudinal side wall, 
 wherein the edge preferably comprises one or more through openings.    
     
     
         12 . Drainage channel according to  claim 1 , wherein a first of the longitudinal side walls comprises a retaining wall projecting substantially perpendicular to the bottom wall and above the drainage channel, 
 wherein the retaining wall preferably is placed shifted at the first longitudinal side wall, at least at an end thereof that faces away from the bottom wall, and    wherein the retaining wall preferably comprises one or more through openings.    
     
     
         13 . Drainage channel according to  claim 1 , wherein the duct part comprises upright transverse side walls situated at the ends thereof.  
     
     
         14 . Drainage channel according to  claim 1 , wherein the bottom wall comprises a wall section inclined to the discharge opening.  
     
     
         15 . Drainage channel according to  claim 1 , wherein at least one longitudinal side wall, at least considered in cross-section of the drainage channel, comprises a leaning wall section, 
 wherein the leaning wall section of the at least one longitudinal side wall, at least considered in cross-section of the drainage channel, preferably leans towards the opposite longitudinal side wall, and preferably comprises a dovetail profile.    
     
     
         16 . Drainage channel according to  claim 1 , wherein the stench-trap, when operative, comprises a water seal.  
     
     
         17 . Drainage channel according to  claim 1 , wherein the discharge opening comprises a non-return valve and/or a dirt collection filter.
