Definitions
- the invention relates to a sanitary insert part, with an inlet side and an outlet side, wherein between the inlet side and the outlet side, a fastening means is formed, wherein the fastening means for releasably securing is formed with a counter-fastening means to a water outlet of a sanitary fitting, wherein between the fastening means and the inlet side a sealing element is formed to an at least partial seal, and with a jet ventilation device having a ventilation access open to the outlet side.
- the invention further relates to an outlet arrangement, with an insert part as described above, which is inserted into a water outlet of a sanitary fitting, wherein the sealing element of the insert at least partially seals a gap between the insert part and the water outlet.
- the invention relates to a use of a discharge opening leading into a jet ventilation device for reducing leakage between an insert part and a water outlet receiving the insert part
- Such a sanitary insert part, such an outlet arrangement and a corresponding use of the type described are known for example from EP3153633 AI.
- the invention has for its object to provide with simple means an alternative method for sealing between a sanitary insert and this receiving water outlet of a sanitary fitting.
- a sanitary insert according to the invention to solve the above problem in a sanitary insert of the type described above is inventively proposed that between the sealing element and the fastener at least one leading from the outside to the jet ventilation device drain opening is formed, which leads into the jet ventilation device.
- drain opening is formed between the sealing element and the fastener between the sealing element and the fastener, which leads into the jet ventilation device.
- a water outlet next to the outlet side past the fastening means is thus significantly reduced or even completely avoidable. It is not necessary in this case to form the sealing element or to press in the water outlet that it seals absolutely. Rather, a certain leakage is acceptable, which can be absorbed via said drain opening. This facilitates the installation of the insert considerably, since this does not have to be mounted with a great effort.
- the sealing element can achieve a complete seal. However, it is already sufficient for the purposes of the invention if the sealing element reaches only a partial seal, from which results in a pressure difference across the sealing element. This pressure difference can be set, for example, such that a substantial part of the water seeping through the sealing element or even all seepage water is led into the drainage opening.
- the fastening means may in this case be designed to be releasably connected to a counter-fastening means.
- the fastening means can be configured to form a screw connection, plug connection, recessed connection and / or snap connection or a combination of one or more of these connection types with one another or with other connection types.
- a main flow path is formed between the inlet side and the outlet side.
- Jet aerator forms a flow obstacle in the main flow path.
- the flow obstruction can thus cause a pressure drop across the inlet side, which allows a return of seepage or leakage flows in the main flow path.
- the drain opening leads in the flow direction behind the flow obstacle in the main flow path.
- a trickle stream must build up a large pressure to flow in the main flow path.
- This can be used, for example, to relieve the outflow opening located seals - which may be formed for example by the fastening means - to relieve.
- It is particularly favorable if a plurality of preferably similar drainage openings are distributed over an outer circumference or if the drainage opening is of annular design.

- the collecting space has an overflow opening, which opens into the ventilation access.
- the collection space is easily emptied into the main flow path.
- a sealing lip is formed, with which the collecting space is sealed in the water outlet to the outside.
- the fastening means is designed as a thread which is formed with a mating thread on a water outlet of a sanitary fitting.
- a thread allows a particularly simple attachment in the water outlet.
- a thread is a flow obstacle when it interacts with the mating thread. As a result, it is particularly serious that leachate on the drain opening and not over the thread runs off.
- a tool approach in particular a slot
- a tool approach is formed to support a fastening operation and / or a release operation.
- a preferred application of the invention is a sanitary fitting with an outlet arrangement according to the invention as described above and / or according to one of the claims directed to an outlet arrangement.

- the water will therefore choose the path of least resistance and drain through the at least thin drainage opening 10 instead along the trickle path 20 between fastener 4 and counter-fastening means 6 to crawl.
- the sealing element 7 also causes a reduction in pressure in the seepage path 20, since a flow resistance generated by the sealing element 7 is greater than a flow resistance in a section of the main flow path in the sanitary insert part 1 that runs parallel to the sealing element 7.
- a as Slot designed tool attachment 18 is formed.
- a tool used in the water outlet 5 sanitary insert 1 by attaching a tool on the tool neck 18 and a preferably defined as rotational movement opening movement of the tool from the water outlet 5 is detachable, in particular Toschraubbar, or also used therein, in particular screwed.
