Abstract

A sanitary insert unit is provided having an aerated jet regulator which has a jet regulator housing with a housing inlet and a housing outlet, and a jets splitter in the housing interior. One feature of the insert unit is that the jet splitter is configured as a pot-shaped diffuser which has a pot base serving as an impingement surface for deflecting the flow of water outwards and a circumferential wall having at least one through-flow opening that leads into an annular channel. The jet regulator has, in a circumferential wall of its jet regulator housing, at least one aeration channel with an outlet opening leads into the housing interior of the jet regulator housing. The opening edge of the channel outlet opening facing towards the housing outlet is arranged above a cross-sectional plane of the jet regulator housing that extends through the outlet-side front face of the jet splitter.

First claim

1 . A sanitary insert unit ( 1 ) comprising an aerated jet regulator ( 3 ) which has a jet regulator housing having a circumferential wall, a housing inlet ( 4 ) and a housing outlet ( 5 ), a jet splitter ( 6 ) located in a housing interior of said jet regulator housing, the jet splitter ( 6 ) is configured as a pot-shaped diffuser which has a pot base ( 7 ) and a circumferential wall, the pot base serving as an impingement surface for deflecting a flow of water outwards and the circumferential wall including at least one through-flow opening ( 8 ) that leads into an annular channel ( 9 ), the jet regulator ( 3 ) has, in the circumferential wall of the jet regulator housing, at least one aeration channel ( 10 ), a channel outlet opening thereof leads into a housing interior of the jet regulator housing, and an opening edge of the channel outlet opening facing towards the housing outlet ( 5 ) is arranged above a cross-sectional plane of the jet regulator housing that extends through an outlet-side front face ( 12 ) of the jet splitter ( 6 ).

2 . The sanitary insert unit according to claim 1 , wherein the opening edge ( 11 ) of the channel outlet opening of the at least one aeration channel ( 10 ) facing towards the housing inlet ( 4 ) is arranged above a cross-sectional plane that extends through an outlet-side channel opening ( 13 ) of the annular channel ( 9 ).

3 . The sanitary insert unit according to claim 1 , wherein the annular channel ( 9 ) narrows, at least in a partial area thereof, in a direction of an outlet-side channel opening thereof.

4 . The sanitary insert unit according to the claim 1 , wherein the jet splitter ( 6 ) protrudes at least in part into a diffuser ring ( 33 ) and, between said jet splitter and the diffuser ring ( 33 ), delimits the annular channel ( 9 ), the diffuser ring ( 33 ) is insertable into an outlet-side housing part of the jet regulator housing until an annular step ( 14 ) arranged on an outer circumference of the diffuser ring ( 33 ) bears on an inlet-side mating surface on the outlet-side housing part, a circumferential locking cam ( 15 ) is provided on the outer circumference of the diffuser ring ( 33 ) and is movable into locking engagement with a locking groove ( 16 ) provided on the inner circumference of the outlet-side housing part ( 26 ), and the locking cam ( 15 ) has a run-on bevel ( 17 ) which interacts with a mating bevel ( 18 ) upstream from the locking groove ( 16 ) in an insertion direction, said mating bevel ( 18 ) has a greater angle of inclination with respect to a longitudinal axis of the jet regulator in comparison with the run-on bevel ( 17 ).

5 . The sanitary insert unit according to claim 4 , wherein the angle of inclination of the mating bevel ( 18 ) is between 40° and 50° and the angle of inclination of the run-on bevel ( 17 ) is between 30° and 40°.

6 . The sanitary insert unit according to claim 5 , wherein the angle of inclination of the mating bevel ( 18 ) is approximately 45° and the angle of inclination of the run-on bevel ( 17 ) is approximately 35°.

7 . The sanitary insert unit according to claim 1 , wherein the jet regulator ( 3 ) is insertable with said jet regulator housing into an outlet mouthpiece ( 2 ) that is mountable on a water outlet of a sanitary outlet fitting, the jet regulator ( 3 ) is sealed off axially by a sealing ring ( 23 ) that is clampable between the jet regulator ( 3 ) and an outlet-side front edge of the outlet fitting, the jet regulator has, on an inlet-side front face, an annular wall ( 24 ) around which the sealing ring ( 23 ) engages, and the sealing ring ( 23 ), on the one hand, protrudes beyond the annular wall ( 24 ) and, on the other hand, protrudes beyond the inlet-side front edge of the outlet mouthpiece ( 2 ).

8 . The sanitary insert unit according to claim 7 , wherein the jet regulator has a jet regulator housing with an inlet-side and an outlet-side housing part ( 26 ), the jet splitter ( 6 ) is configured as a diffuser or as a perforated plate and insertable into the inlet-side housing part from a direction of the inlet-side front face of the housing, and the annular wall ( 24 ) is arranged on an inlet-side front face of the jet splitter ( 6 ).

9 . The sanitary insert unit according to claim 7 , wherein the annular wall ( 24 ) engages around a regulator housing ( 27 ) of a flow rate regulator ( 20 ).

10 . The sanitary insert unit according to claim 9 , wherein the flow rate regulator ( 20 ) is connected, on an inlet-side front face thereof, to a dome screen or filter screen ( 19 ).

11 . The sanitary insert unit according to claim 9 , further comprising a locking connection provided between the annular wall ( 24 ) and the regulator housing ( 27 ).

12 . A sanitary insert unit ( 1 ) comprising an aerated jet regulator ( 3 ) which has a jet regulator housing with a housing inlet ( 4 ), a housing outlet ( 5 ), and a jet splitter ( 6 ) in a housing interior of said jet regulator housing, the jet splitter ( 6 ) protrudes at least in part into a diffuser ring ( 33 ) and, between the jet splitter and the diffuser ring ( 33 ), delimits an annular channel ( 9 ), the diffuser ring ( 33 ) is insertable into an outlet-side housing part ( 14 ) of the jet regulator housing until an annular step ( 14 ) arranged on the outer circumference of the diffuser ring ( 33 ) bears on an inlet-side mating surface on an outlet-side housing part, a circumferential locking cam ( 15 ) is provided on an outer circumference of the diffuser ring ( 33 ) and is movable into locking engagement with a locking groove ( 16 ) provided on an inner circumference of the outlet-side housing part ( 26 ), and the locking cam ( 15 ) has a run-on bevel ( 17 ) which interacts with a mating bevel ( 18 ) upstream from the locking groove ( 16 ) in an insertion direction, said mating bevel ( 18 ) has a greater angle of inclination with respect to a longitudinal axis of the jet regulator in comparison with the run-on bevel ( 17 ).
