Shower drainage outlet in aircraft

1. A shower drainage outlet for a shower tub in an aircraft, the shower drainage outlet comprising a housing with:

a first part having a bearing region;

a second part; and

a third part;

wherein the first part is designed to be inserted into an opening in the shower tub;

wherein the second part is designed for connecting the first part to the third part;

wherein the third part is designed to be connected to a waste water pipe;

wherein an overlap between the bearing region and the top of the shower tub is provided after final installation of the drainage outlet so that displacement between the bearing region and the top of the shower tub during flight does not result in a reduction in a sealing integrity between these two elements;

wherein as a result of this overlap horizontal tolerances between the shower tub and the waste water pipe can be compensated for; and

wherein the first part is designed to be inserted into the second part so that a sliding connection is provided after final installation of the drainage outlet, which connection is adapted for compensation of any angular or vertical tolerances between the shower tub and the floor of the shower cabin or the floor of the aircraft cabin during flight.

2. The shower drainage outlet of claim 1 ,

wherein the bearing region rests against the top of the shower tub in a waterproof manner.

3. The shower drainage outlet of claim 1 ,

wherein the second part comprises a floor adapter for attachment to the floor of a shower cabin or to the floor of an aircraft cabin.

4. The shower drainage outlet of claim 1 ,

wherein the floor adaptor is designed to be at least one of bonded, screwed, and squeezed to at least one of the floor of the shower cabin and to the floor of the aircraft cabin so that a waterproof seal between the floor and the floor adapter results.

5. The shower drainage outlet of claim 1 , further comprising:

a first sealing element for sealing the sliding connection between the first part and the second part.

6. The shower drainage outlet of claim 1 , further comprising:

a coupling element for connecting the second part to the third part;

wherein the coupling element is designed to compensate for tolerances between the floor of the shower cabin or the floor of the aircraft cabin and the waste water pipe.

7. The shower drainage outlet of claim 6 ,

wherein the coupling element is a coupling element according to SAE-AS1650.

8. The shower drainage outlet of claim 1 , further comprising:

a filter within the housing to protect the waste water pipe from dirt as a result of coarse impurities contained in the shower water.

9. The shower drainage outlet of claim 8 , further comprising:

a second sealing element between the filter and the first part to ensure a flow through the filter from the inside to the outside;

wherein the filter comprises a mesh width of 2 mm and a filter area of 0.012 to 0.016 m 2 .

10. A waste water system for an aircraft, with the waste water system comprising:

a shower drainage outlet of claim 1 ; and

a waste water pipe;

wherein the shower drainage outlet is designed to connect the waste water pipe to a shower tub through a floor structure while compensating for vertical and angular tolerances.

11. The shower drainage outlet of claim 1 , wherein during flight the first part is slidable relative to the top of the shower tub so as to maintain the overlap during flight operation.

12. The shower drainage outlet of claim 1 , wherein the bearing region of the first part comprises a seal.
