Sanitary water-outlet fitting with jet regulator for deflecting the exiting water jet

Abstract

A sanitary water-outlet fitting ( 1 ) which has a water outlet ( 2 ) that is provided on the outflow side in the region of the water outlet ( 2 ), with a flow guide ( 3 ) which has at least one perforated plate ( 4 ), screen or lamellar structure with a number of outlet holes or outlet openings ( 6 ) surrounded by flow-guide walls ( 7 ). The flow guide ( 3 ) is configured as a jet regulator, and the flow-guide walls ( 7 ) of at least individual outlet holes or outlet openings ( 6 ) are arranged at an angle to the flow direction of the water flowing into the flow guide ( 3 ) on the inflow side, and the flow-guide walls ( 7 ) of these outlet holes or outlet openings ( 6 ) deflect the inflowing water stream in a direction of their longitudinal extent. It has been found that such a flow guide ( 3 ) is capable of deflecting the water in the direction of the axial position of the flow-guide walls ( 7 ), even in the case of the flow guide ( 3 ) having a comparatively short longitudinal extent in the axial direction. It is thus possible to dispense with ball-and-socket joints which take up a lot of space and may be unsightly.

1 . Sanitary water outlet fitting ( 1 ) comprising a water outlet ( 2 ), and in a region of the water outlet ( 2 ), on an outflow side, there is a flow guide ( 3 ) comprising at least one of a perforated plate ( 4 ), a screen or lamellar structure ( 5 ), the flow guide ( 3 ) has a number of outlet holes or outlet openings ( 6 ) surrounded by flow guide walls ( 7 ) the flow guide ( 3 ) is formed as a jet directional dispenser, the flow guide walls ( 7 ) of at least individual ones of the outlet holes or outlet openings ( 6 ) are arranged at an angle to a flow direction of water flowing into the flow guide on an inflow side, and the flow guide walls ( 7 ) of the outlet holes or outlet openings ( 6 ) deflect the incoming water flow in a direction of their longitudinal extent. 
   
   
       2 . Water outlet fitting according to  claim 1 , wherein the outlet holes or outlet openings ( 6 ) of the at least one perforated plate ( 4 ) of the flow guide ( 3 ) have a circular or polygonal opening cross section. 
   
   
       3 . Water outlet fitting according to  claim 1 , wherein the outlet holes or outlet openings ( 6 ) of the at least one perforated plate ( 4 ) of the flow guide ( 3 ) have a hexagonal opening cross section and are arranged like a honeycomb relative to each other. 
   
   
       4 . Water outlet fitting according to  claim 1 , wherein a jet regulator is connected before the flow guide ( 3 ) in the flow direction. 
   
   
       5 . Water outlet fitting according to  claim 1 , wherein the water jet flowing into the flow guide ( 3 ) is an aerated water jet. 
   
   
       6 . Water outlet fitting according to one  claim 1 , wherein the flow guide ( 3 ) has several of the perforated plates ( 4 ), screens or lamellar structures ( 5 ) that are spaced apart from each other. 
   
   
       7 . Water outlet fitting according to  claim 6 , wherein the perforated plates ( 4 ), screens or lamellar structures ( 5 ) of the flow guide ( 3 ) are arranged at an angle that is equal to or that increases relative to the flow direction of the incoming water. 
   
   
       8 . Water outlet fitting according to  claim 1 , wherein the at least one of the perforated plate ( 4 ), screen or lamellar structure ( 5 ) of the flow guide ( 3 ) arranged on the outflow side is bowed. 
   
   
       9 . Water outlet fitting according to  claim 1 , wherein the at least one of the perforated plate ( 4 ), screen or lamellar structure ( 5 ) is produced as a separate component and is later connected to an outflow-side front edge of the outlet fitting ( 1 ) for forming a bowed or non-flat shape or for adapting the perforated plate ( 4 ), screen or lamellar structure ( 5 ) to a relief of the outflow-side front edge. 
   
   
       10 . Water outlet fitting according to  claim 1 , wherein the outlet holes or outlet openings ( 6 ) have approximately coaxial longitudinal axes. 
   
   
       11 . Water outlet fittings according to  claim 1 , wherein the longitudinal axes of the outlet holes or outlet openings ( 6 ) diverge. 
   
   
       12 . Water outlet fitting according to  claim 1 , wherein the longitudinal axes of at least the outlet holes or outlet openings ( 6 ) provided in an outer edge region of the perforated plate ( 4 ) are directed outwardly. 
   
   
       13 . Water outlet fitting according to  claim 1 , wherein the at least one of the perforated plate ( 4 ), screen or lamellar structure ( 5 ) of the flow guide ( 3 ) arranged on the outflow side is flat. 
   
   
       14 . Water outlet fittings according to  claim 1 , wherein the longitudinal axes of the outlet holes or outlet openings ( 6 ) converge. 
   
   
       15 . Water outlet fitting according to  claim 1 , wherein the longitudinal axes of at least the outlet holes or outlet openings ( 6 ) provided in an outer edge region of the perforated plate ( 4 ) are directed inwardly.
