Sanitary outflow part and corresponding use
In the case of a sanitary outflow part ( 1 ), it is provided that, between an inlet opening ( 2 ) and an outlet opening ( 3 ), in a flow path ( 4 ) which leads through a jet regulator unit ( 5 ), a secondary outlet ( 7 ) branches off downstream of the jet regulator unit ( 5 ). This secondary outlet leads to an additional secondary outlet opening ( 8 ) such that water entering via the inlet opening ( 2 ) emerges to the secondary outlet opening ( 8 ) at least when the outlet opening ( 3 ) of the sanitary outflow part ( 1 ) is closed off.
1. A sanitary outflow part ( 1 ), comprising:
a housing with an inlet opening ( 2 ), which is adapted to be fastened to a fitting, and an outlet opening ( 3 ),
a jet regulator unit ( 5 ) with at least one aeration opening ( 6 ) arranged in a flow path ( 4 ) between the inlet opening ( 2 ) and the outlet opening ( 3 ),
a secondary outlet ( 7 ) that branches off in the flow path ( 4 ) between the jet regulator unit ( 5 ) and the outlet opening ( 3 ) that leads out in a laterally spaced-apart manner to a separate secondary outlet opening ( 8 ) and
an aeration chamber ( 12 ) formed between the inlet opening ( 2 ) and the outlet opening ( 3 ), said aeration chamber extends outside the flow path ( 4 ), and the at least one aeration opening ( 6 ) is connected to the aeration chamber ( 12 ), wherein the secondary outlet ( 7 ) is branched off from the aeration chamber ( 12 ).
2. The sanitary outflow part ( 1 ) as claimed in claim 1 , wherein the secondary outlet opening ( 8 ) is formed above the jet regulator unit ( 5 ) in a usage position.
3. The sanitary outflow part ( 1 ) as claimed in claim 1 , wherein the secondary outlet ( 7 ) forms a duct ( 9 ) which runs at an angle with respect to the flow path ( 4 ) and counter to a flow direction of the flow path ( 4 ), and the secondary outlet opening ( 8 ) is formed at an open end ( 25 ) of the duct ( 9 ).
4. The sanitary outflow part ( 1 ) as claimed in claim 1 , wherein the flow path ( 4 ) is formed without a valve downstream of the jet regulator unit ( 5 ).
5. The sanitary outflow part ( 1 ) as claimed in claim 1 , wherein the aeration chamber ( 12 ) is ring-shaped, and the at least one aeration opening ( 6 ) is capable of being fed with air from the aeration chamber ( 12 ) during use.
6. The sanitary outflow part ( 1 ) as claimed in claim 1 , wherein the aeration chamber ( 12 ) is separated from the flow path ( 4 ) by a closed wall ( 13 ) in which the at least one aeration opening ( 6 ) is formed.
7. The sanitary outflow part ( 1 ) as claimed in claim 6 , wherein at least one diffuser exit opening ( 16 ) is arranged radially within the closed wall ( 13 ).
8. The sanitary outflow part ( 1 ) as claimed in claim 1 , wherein an internal diameter of the outlet opening ( 3 ) is coordinated with a jet diameter predefined by the jet regulator unit ( 5 ).
9. The sanitary outflow part ( 1 ) as claimed in claim 1 , wherein the jet regulator unit ( 5 ) includes at least one of a diffuser ( 14 ) or a flow rate regulator ( 15 ).
10. The sanitary outflow part ( 1 ) as claimed in claim 1 , wherein, on the inlet opening ( 2 ), there is formed a thread ( 19 ) which is adapted to be screwed together with a counterpart thread of a fitting.
11. The sanitary outflow part ( 1 ) as claimed in claim 1 , further comprising a sealing ring ( 20 ) placed into the inlet opening ( 2 ).
12. The sanitary outflow part ( 1 ) as claimed in claim 1 , wherein the jet regulator unit ( 5 ) is at least one of insertable or removable as a cartridge ( 21 ) via the inlet opening ( 2 ).
13. The sanitary outflow part ( 1 ) as claimed in claim 1 , wherein the housing ( 22 ) which forms the inlet opening ( 2 ), the outlet opening ( 3 ), and the secondary outlet opening ( 8 ) is manufactured from a dimensionally stable material.
14. The sanitary outflow part ( 1 ) as claimed in claim 1 , wherein the jet regulator unit ( 5 ) is inserted into the outlet opening ( 3 ).
15. The sanitary outflow part ( 1 ) as claimed in claim 1 , wherein the outlet opening ( 3 ) is adapted to be closed off using a finger.
16. The sanitary outflow part ( 1 ) as claimed in claim 1 , wherein the aeration chamber ( 12 ) is sealed downstream of the secondary outlet ( 7 ).
17. A method of providing an alternate water flow from a sanitary fitting, comprising providing the sanitary outflow part ( 1 ) as claimed in claim 1 , attaching the sanitary outflow part ( 1 ) onto the sanitary fitting, and closing the outlet opening ( 3 ) such that the alternate water flow is discharged from the separate secondary outlet opening ( 8 ).
18. The method of claim 17 , wherein the sanitary fitting is of a wash basin or drinking basin.
19. The method of claim 17 , wherein the sanitary outflow part ( 1 ) is mounted by screw fastening on an outflow of the sanitary fitting.
20. The method of claim 17 , wherein an air stream eventually sucked in through the at least one aeration opening ( 6 ) is used for drying the secondary outlet ( 7 ).
