Sanitary insert unit

Abstract

A sanitary insert unit ( 1 ), which can be inserted into a discharge fitting is provided, comprising a substantially conically-shaped upstream sieve ( 2 ) with a downstream-located throughflow regulator ( 3 ) and a jet regulator ( 4 ) in a direction of flow. The throughflow regulator ( 3 ) is arranged substantially inside the inner area ( 6 ) of the insert unit, which is defined on theupper side by the upstream sieve ( 2 ). The throughflow regulator ( 3 ) has a cross-sectional shape that is substantially adapted to the cross-sectional profile of the upstream sieve ( 2 ). The throughflow regulator ( 3 ) has a rising sloping surface ( 9 ) which rises gradually in a radially inward manner from an outer, particularly annular, edge area and which leads to a control gap ( 10 ) or a similar throughflow opening that leads to the jet regulator ( 4 ). The rising sloping surface ( 9 ) and the upstream sieve are spaced apart from one another.

1 . A sanitary unit ( 1 ) for insertion into a discharge fitting, comprising a substantially cone-shaped upstream sieve ( 2 ), with a throughflow regulator ( 3 ) and a jet regulator ( 4 ) positioned downstream in a flow direction, wherein the throughflow regulator ( 3 ) is arranged generally inside an interior space ( 6 ) of the insert unit ( 1 ) limited at a top thereof by the upstream sieve ( 2 ).  
   
   
       2 . An insert unit according to  claim 1 , wherein the throughflow regulator ( 3 ) is provided with a cross-sectional profile substantially form-fitting a cross-sectional profile of the upstream sieve ( 2 ).  
   
   
       3 . An insert unit according to  claim 1 , wherein the throughflow regulator ( 3 ) is provided on an exterior, edge region with a radially inward rising sloping surface ( 9 ), which leads to a throughflow opening connected to a control gap ( 10 ) provided with the jet regulator ( 4 ) and the rising sloping surface ( 9 ) and the upstream sieve ( 2 ) are spaced apart from one another.  
   
   
       4 . An insert unit according to  claim 3 , wherein the rising sloped surface ( 9 ) is provided at an upper side thereof with approximately radially aligned grooves ( 11 ) in order to form individual influx channels.  
   
   
       5 . An insert unit according to  claim 4 , wherein bars ( 12 ) are located between the grooves ( 11 ) and end in close proximity or at an interior side of the upstream sieve ( 2 ) and serve as support elements for the upstream sieve ( 2 ).  
   
   
       6 . An insert unit according to  claim 5 , wherein the bars ( 12 ) of the rising sloped surface ( 9 ) are evenly spaced apart from one another in a circumferential direction.  
   
   
       7 . An insert unit according to  claim 3 , wherein the throughflow regulator ( 3 ) is provided with a central core area ( 7 ), which is surrounded by a circular throttle body ( 8 ), and between the throttle body ( 8 ) and the rising sloped surface ( 9 ) a control gap ( 10 ) is formed, having a throughflow cross-section being adjustable by the throttle body ( 8 ) deformed under varying pressure arising during the throughflow.
