Abstract

The invention relates to a sanitary shower ( 1 ) comprising at least a housing ( 2 ), at least one fluid inlet ( 3 ) for a fluid, and at least one jet-forming element ( 4 ) with at least one fluid channel ( 19 ), the at least one fluid channel ( 19 ) comprising at least one duckbill valve ( 6 ) having an elastic valve casing ( 7 ) that runs in a flow direction ( 8 ) of the fluid from a valve base ( 9 ) to a slotted valve outlet ( 10 ). The valve casing ( 7 ), at least in the region of the slotted valve outlet ( 10 ), has an outwardly oriented thicker portion ( 12 ).

First claim

The invention claimed is:

1. A sanitary shower ( 1 ), comprising:
a housing ( 2 ),
at least one fluid inlet ( 3 ) for a fluid, and
at least one jet-forming element ( 4 ) comprising at least one fluid duct ( 19 ) and at least one nozzle ( 5 ), wherein the at least one fluid duct ( 19 ) comprises at least one duckbill valve ( 6 ) having an elastic valve jacket ( 7 ), which extends in a direction of flow ( 8 ) of the fluid from a valve base ( 9 ) to a slit-shaped valve outlet ( 10 ), wherein the valve jacket ( 7 ) comprises a thickening ( 12 ) directed outwards at least in an area of the slit-shaped valve outlet ( 10 ), and wherein the valve jacket ( 7 ) comprises a first wall thickness ( 13 ) outside the thickening ( 12 ) and a second wall thickness ( 14 ) in an area of the thickening ( 12 ) that is at least 10% greater than the first wall thickness ( 13 ).

2. The sanitary shower ( 1 ) according to claim 1 , wherein the thickening ( 12 ) is formed at least partially convex.

3. The sanitary shower ( 1 ) according to claim 1 , wherein the thickening ( 12 ) is formed at least partially concave.

4. The sanitary shower ( 1 ) according to claim 1 , wherein the thickening ( 12 ) is formed at least partially in the manner of at least one web ( 15 , 16 ).

5. The sanitary shower ( 1 ) according to claim 4 , wherein the at least one web ( 15 , 16 ) extends from the valve base ( 9 ) to the slit-shaped valve outlet ( 10 ).

6. The sanitary shower ( 1 ) according to claim 4 , wherein the at least one web ( 15 , 16 ) extends from an outer surface ( 17 ) of the valve jacket ( 7 ) to an inner wall ( 18 ) of the at least one fluid duct ( 19 ) of the at least one nozzle ( 5 ).

7. The sanitary shower ( 1 ) according to claim 4 , wherein the at least one web ( 15 , 16 ) has a web width ( 20 ) of 0.1 mm to 0.5 mm.

8. The sanitary shower ( 1 ) according to claim 4 , wherein the at least one web ( 15 , 16 ) extends orthogonally to the slit-shaped valve outlet ( 10 ).

9. The sanitary shower ( 1 ) according to claim 1 , wherein the thickening ( 12 ) can be at least partially elastically deformed when the slit-shaped valve outlet ( 10 ) is opened.

10. The sanitary shower ( 1 ) according to claim 1 , wherein the thickening ( 12 ) has a length of 0.2 mm to 1 mm.

11. The sanitary shower ( 1 ) according to claim 1 , wherein the first wall thickness ( 13 ) is 0.1 mm to 0.5 mm.
