Abstract

A sanitary fixture ( 6 ) is provided having a mounting housing ( 9 ) which has a thread ( 10 ) for fastening to a mating thread provided on the water outlet of a sanitary outlet fitting. The mounting housing ( 9 ) has a downstream housing end side ( 12 ) with flow-through holes ( 13 ), and wherein at least one insertion part can be inserted into the mounting housing ( 9 ) as far as an insertion stop. According to one of the solution proposals described here, it is provided that the fixture ( 6 ) has an aerated jet regulator ( 16 ) or is configured as such, that the circumferential wall of the mounting housing ( 9 ) borders at least one aeration duct ( 14 ) at least in a subregion of at least double-walled configuration, and that the at least one aeration duct ( 14 ), which is open towards the downstream housing end side ( 12 ), opens out in at least one aeration opening ( 15 ) leading into the housing interior of the mounting housing.

First claim

The invention claimed is:

1. Sanitary fixture ( 1 , 2 , 4 , 5 , 6 , 7 ) comprising a mounting housing ( 9 ) which has a thread ( 10 ) for fastening to a mating thread ( 11 ) provided on a water outlet ( 70 ) of a sanitary outlet fitting ( 8 ), wherein the mounting housing ( 9 ) has a downstream housing end side ( 12 ) with flow-through holes ( 13 ), and wherein at least one insertion part can be inserted into the mounting housing ( 9 ) as far as an insertion stop, the fixture ( 1 , 2 , 4 , 5 , 6 , 7 ) has an aerated jet regulator or is configured as such, in that a circumferential wall of the mounting housing ( 9 ) borders at least one aeration duct ( 14 ) at least in a subregion of at least a double-walled configuration, and the at least one aeration duct ( 14 ), which is open towards the downstream housing end side ( 12 ), opens out in at least one aeration opening ( 15 ) leading into a housing interior of the mounting housing ( 9 ), wherein the downstream housing end side ( 12 ) is of convexly or spherically curved design in a downstream direction and has at least one slot ( 20 , 21 ) with opposing slot longitudinal sides that are configured as rotation or tool engagement surfaces for a rotation tool which can be inserted into the at least one slot ( 20 , 21 ), and wherein the thread ( 10 ) provided on the mounting housing ( 9 ) is an external thread which is arranged on an outer circumference of the housing ( 9 ) and interacts with an internal thread ( 11 ) which is located on an inner circumference of the water outlet ( 70 ) provided in the form of a mating thread ( 11 ).

2. The fixture according to claim 1 , wherein the downstream housing end side ( 12 ) is configured as a grate, mesh or perforated structure.

3. The fixture according to claim 1 , wherein the at least one slot ( 20 , 21 ) on the downstream housing end side ( 12 ) has a slot or groove base which is configured to be closed, or to be open or liquid-permeable via a perforated or grate structure forming the slot or groove base.

4. The fixture according to claim 3 , wherein the housing end side ( 12 ) has at least one of a cross-sectional thickened portion at least in the region of the at least one slot ( 20 , 21 ), or the slot longitudinal sides of the at least one slot ( 20 , 21 ) have a greater wall thickness than flow-guiding walls ( 46 ) forming a grate, mesh or perforated structure of the downstream housing end side ( 12 ).

5. The fixture according to claim 1 , further comprising a plurality of aeration openings ( 15 ) distributed uniformly over a housing circumference.

6. The fixture according to claim 1 , wherein the jet regulator ( 16 ) has an insertion part which is configured as a jet splitter and divides a stream of water into a multiplicity of individual jets, and the at least one aeration opening ( 15 ) opens out in a housing interior section following the jet splitter in a direction of flow.

7. The fixture according to claim 6 , wherein the jet splitter has a multiplicity of flow-through openings ( 22 , 41 ) for dividing the stream of water into the multiplicity of individual jets.

8. The fixture according to claim 6 , wherein the jet splitter is a perforated plate ( 40 ) or a diffuser ( 23 ).

9. The fixture according to claim 1 , wherein the fixture ( 1 , 2 , 4 , 5 , 6 ) has at least one of a flow-through quantity regulator ( 34 ) or a baffle connected upstream of the aerated jet regulator in a flow direction.

10. The fixture according to claim 1 , further comprising an annular seal ( 33 ) for axial sealing between the fixture and an annular step located in the water outlet ( 7 ).

11. Sanitary fixture ( 1 , 2 , 4 , 5 , 6 , 7 ) comprising a mounting housing ( 9 ) which has a thread ( 10 ) for fastening to a mating thread ( 11 ) provided on a water outlet ( 70 ) of a sanitary outlet fitting ( 8 ), wherein the mounting housing ( 9 ) has a downstream housing end side ( 12 ) with flow-through holes ( 13 ), and wherein at least one insertion part can be inserted into the mounting housing ( 9 ) as far as an insertion stop, the fixture ( 1 , 2 , 4 , 5 , 6 , 7 ) has an aerated jet regulator or is configured as such, in that a circumferential wall of the mounting housing ( 9 ) borders at least one aeration duct ( 14 ) at least in a subregion of at least a double-walled configuration, and the at least one aeration duct ( 14 ), which is open towards the downstream housing end side ( 12 ), opens out in at least one aeration opening ( 15 ) leading into a housing interior of the mounting housing ( 9 ), wherein the downstream housing end side ( 12 ) is of convexly or spherically curved design in a downstream direction and has at least one slot ( 20 , 21 ) with opposing slot longitudinal sides that are configured as rotation or tool engagement surfaces for a rotation tool which can be inserted into the at least one slot ( 20 , 21 ), the fixture ( 1 , 2 , 4 , 5 , 6 , 7 ) further comprises at least one of a flow-through quantity regulator ( 34 ) or a baffle connected upstream of the aerated jet regulator in a flow direction, and an ancillary sieve ( 38 ) is connected upstream of the aerated jet regulator and optionally the flow-through quantity regulator ( 34 ) in the flow direction.

12. Sanitary fixture ( 1 , 2 , 4 , 5 , 6 , 7 ) comprising a mounting housing ( 9 ) which has a thread ( 10 ) for fastening to a mating thread ( 11 ) provided on a water outlet ( 70 ) of a sanitary outlet fitting ( 8 ), wherein the mounting housing ( 9 ) comprises a double wall portion defined by an outer housing wall ( 17 ), bearing a portion of the thread ( 10 ) and an inner housing wall ( 18 ), and has a downstream housing end side ( 12 ) with flow-through holes ( 13 ), and wherein at least one insertion part can be inserted into the mounting housing ( 9 ) as far as an insertion stop, the fixture ( 1 , 2 , 4 , 5 , 6 , 7 ) further comprises at least one aeration duct ( 14 ) at least in a subregion of at least a double-walled configuration, the at least one aeration duct ( 14 ), is delimited by the inner and outer housing walls ( 18 , 17 ) and by radial webs ( 19 ), which connect the inner and outer housing walls ( 18 , 17 ), and which is axially open towards the downstream housing end side ( 12 ), opens out in at least one aeration opening ( 15 ) leading into a housing interior of the mounting housing ( 9 ).
