Sanitary outlet device
A sanitary outlet device ( 1, 2 ) including a housing ( 3 ) which has a fitting receptacle ( 6 ) with a thread ( 7 ) at an inflow end of a flow path ( 11 ). A mating thread ( 8 ) of a fitting outlet ( 12 ) can be screwed together with the thread ( 7 ). An outflow-side end of the thread ( 7 ) is equipped with a seal ( 9 ) by which the flow path ( 11 ) of the water flowing through a flow channel of the sanitary outlet device ( 1, 2 ) can be sealed outwards at a transition between a screwed-in fixture outlet ( 12 ) and the housing ( 3 ). The seal ( 9 ) forms an inner surface ( 10 ), which can be wetted by water flowing in the flow path ( 11 ) and which is free of rubber, at the transition.
1. A sanitary outlet device ( 1 , 2 ), comprising a housing ( 3 ) having a flow path ( 11 ) therethrough, a fitting receptacle ( 6 ) at an inflow end of the flow path ( 11 ), the fitting receptacle ( 6 ) having a thread ( 7 ) that is adapted to be screwed together with a counterpart thread ( 8 ) of a fitting outlet ( 12 ), a seal formed on the inflow side of the housing, the seal ( 9 ) is formed such that the flow path ( 11 ) is able to be sealed off from outside at a transition from the screwed-in fitting outlet ( 12 ) to the housing ( 3 ), the seal ( 9 ) forms, at the transition, an inner face ( 10 ) that is adapted to be wettable by flowing water in the flow path ( 11 ), the inner face ( 10 ) is formed in a rubber-free manner, the seal ( 9 ) has a protrusion ( 13 ) that extends in an encircling manner in the fitting receptacle ( 6 ) and forms the rubber-free inner face ( 10 ) which is rubber-free on a side facing the flow path ( 11 ), the protrusion ( 13 ) is integrally formed on the housing ( 3 ) and is connected thereto in one piece, the protrusion ( 13 ) delimits a groove ( 15 ), extending in an encircling manner in the fitting receptacle ( 6 ), with respect to the flow path ( 11 ), the groove ( 15 ) is open counter to a screwing direction ( 20 ) defined by the thread ( 7 ), the protrusion ( 13 ) has a contact face oriented counter to the screwing direction ( 20 ) and forms a stop for the screwed-in fitting outlet, a rubber ring ( 16 ) is located in the groove ( 15 ), at least one of the rubber ring ( 16 ) protrudes from the groove ( 15 ) in an unloaded state, counter to a screwing direction ( 20 ), or the groove ( 15 ) is formed less deeply than is necessary to fully receive the rubber ring ( 16 ), and the groove ( 15 ) is dimensioned such that the rubber ring ( 16 ) is receivable without sticking out in a compressed state.
2. The sanitary outlet device ( 1 , 2 ) according to claim 1 , wherein the seal ( 9 ) includes the protrusion ( 13 ) that extends in an encircling manner in the fitting receptacle ( 6 ) and forms the rubber-free inner face ( 10 ) on a side facing the flow path ( 11 ), the protrusion ( 13 ) is integrally formed on the housing ( 3 ) and is connected thereto in one piece, and the protrusion ( 13 ) is made of a deformable material.
3. The sanitary outlet device ( 1 , 2 ) as claimed in claim 1 , wherein the seal ( 9 ) has the protrusion ( 13 ) that extends in the encircling manner in the fitting receptacle ( 6 ) and protrudes into the fitting receptacle ( 6 ) counter to the screwing direction ( 20 ), defined by the thread ( 7 ), on the housing ( 3 ).
4. The sanitary outlet device ( 1 , 2 ) as claimed in claim 1 , wherein the protrusion ( 13 ) that extends in the encircling manner in the fitting receptacle ( 6 ) is formed radially within the thread ( 7 ) or radially at a distance from the thread ( 7 ).
5. The sanitary outlet device ( 1 , 2 ) as claimed in one claim 1 , wherein the protrusion ( 13 ) is made of plastic.
6. The sanitary outlet device ( 1 , 2 ) as claimed in claim 1 , wherein the protrusion ( 13 ) has a cross-sectional profile that narrows counter to the screwing direction ( 20 ) defined by the thread ( 7 ).
7. The sanitary outlet device ( 1 , 2 ) as claimed in claim 1 , wherein the thread ( 7 ) allows the fitting outlet ( 12 ) to be screwed beyond an inflow-side end of the protrusion ( 13 ).
8. The sanitary outlet device ( 1 , 2 ) as claimed in claim 1 , wherein the rubber ring ( 16 ) has a nonround cross-sectional profile.
9. The sanitary outlet device ( 1 , 2 ) as claimed in claim 1 , wherein a volume of the groove ( 15 ) is greater than a volume of the rubber ring ( 16 ).
10. The sanitary outlet device ( 1 , 2 ) as claimed in claim 1 , wherein the housing ( 3 ) is made of metal at least at the fitting receptacle ( 6 ).
11. The sanitary outlet device ( 1 , 2 ) as claimed in claim 1 , wherein the housing ( 3 ) transitions, on an outflow side with respect to the rubber-free inner face ( 10 ), into a widening jet former receptacle ( 4 ), into which a jet former ( 5 ) is inserted in a removable manner.
12. The sanitary outlet device ( 1 , 2 ) as claimed in claim 11 , wherein the jet former ( 5 ) is deformed, in the inserted state, at least at an inflow-side end thereof, by the jet former receptacle ( 4 ).
13. The sanitary outlet device ( 1 , 2 ) as claimed in claim 11 , wherein the jet former ( 5 ) is made of plastic.
14. The sanitary outlet device ( 1 , 2 ) as claimed in claim 11 , the jet former ( 5 ) has, at an inflow-side end thereof, a sealing lip ( 17 ) that bears on the jet former receptacle ( 4 ) or a sealing ring ( 22 ) that bears on the jet former receptacle ( 4 ), or both.
