DETAILED DESCRIPTION

[0033] FIG. 1 shows an aircraft cabin monument 1 with its lower main body 2 in a view from the front. As can be seen, the cabin monument 1 is configured as a galley. For this purpose, the lower main body 2 of the cabin monument 1 is provided with a stowage space 3 for catering containers 7, what are known as trolleys. Side walls 5 form the lateral and inner boundaries, in order to realize trolley berths 6. A cover plate 4 forms the upper limit and preferably forms a working surface of the kitchen. The stowage space 3 is configured as a cooling chamber and comprises a thermally insulated space which is sealed against leaks. For this purpose, doors 3A to the trolley berths 6 are provided in each case. Furthermore, the walls 4 and 5 are preferably provided with insulation, and seals 8 are provided between the side walls 5 and the aircraft floor. The seals 8 can usually be configured as elastomer seals, lamellar seals or squeeze-type elastomer seals. Brush seals can be provided in the region of the doors 3A to the stowage space 3.

[0034] The galley 1 likewise has a cooling apparatus 10 which is preferably arranged in the rearward region of the galley 1. This can be seen clearly in the sectional illustration from the side in FIG. 2. The cooling apparatus 10 here is a cooling unit which cools air as a cooling medium to the required temperature and conducts the cooling air into the stowage space 3 via a plurality of cooling air outlets 11 and allows it to flow over the catering containers 7. The heated cooling air is removed from the stowage space 3 again via a plurality of return air inlets 12. A cooling principle of this type is called air-over cooling. The side view in FIG. 2 shows what is known as a half-sized trolley 7 which has been pushed into the stowage space 3 to such an extent that it is positioned with its rear wall on the cooling apparatus 10. This design of the trolley 7 makes it possible that a further half-sized trolley can be positioned in the front region of the trolley berth 6. The catering containers (trolleys) 7 are not insulated themselves for a cooling system of this type, but rather are flowed around and possibly flowed through by the cooling air, and the foodstuffs and beverages which are stored in the catering container 7 are therefore cooled.

[0035] In the cooled stowage space 3, condensed water can form on the surfaces on account of the cold cooling air. Condensed water is formed, for example, if warmer water-containing air passes into the stowage space 3. Furthermore, it occurs during starting of the cooling system; at that point, the air in the stowage space 3 is then cooled and condenses. This product of the condensation of water from the air which is also called condensate can drip onto the aircraft floor. The the condensed water occurs, in particular, at the bottom below the cooling apparatus 10 as a result of condensate which drips down, and can be collected by way of a drip pan 13 in accordance with the disclosure herein. Accumulations of water can therefore be avoided in the region of the galley 1 in the bottom region of the trolley stowage space 3. This advantageously achieves a situation where no moisture occurs and no water flows over the floor in the region of the working area which is utilized by the cabin crew.

[0036] FIG. 3 shows a perspective view of a detail of the stowage space 3 of a galley 1. The the stowage space which is shown has, as a trolley berth 6 for a trolley 7, side walls 5 which are sealed with respect to the aircraft floor 21 by way of seals 8. The seals 8 are arranged on bars 9 for simple mounting. The bars 9 serve at the same time as protective bars or covering bars which are fastened to the side walls 5 in such a way that the seals 8 are positioned in a sealing manner with respect to the aircraft floor 21. The seals 8 also run in the rearward region of the galley 1 as a seal between the rear wall and the aircraft floor 21. Details of the cover plate 4 can likewise be seen. The cooling apparatus 10 is arranged in the rearward region of the galley 1. The drip pan 13 is positioned along the rear wall on the aircraft floor 21 below the the cooling apparatus 10.

[0037] FIG. 4 shows a perspective partial illustration of the drip pan 13 according to the disclosure herein and its positioning on the aircraft floor 21 in the stowage space 3 of the galley 1. The drip pan 13 corresponds to the width of the trolley compartment 6 and terminates by way of the front edge region with a floor boundary portion 16 to the aircraft floor 21. The depth of the drip pan 13 is selected in such a way that firstly the depth of the cooling apparatus 10 is taken into consideration and secondly positioning of the trolley wheels of the trolley 7 on the trolley berth 6 is not impeded or impaired. In this way, the handling of the catering containers is not restricted. The rear edge region is configured as a transition portion 18 to the rear seal 8. The latter is preferably configured as a continuous edge, in order not to produce any additional cleaning regions or surfaces for cleaning of the seals. The collecting portion 17 forms substantially the drip pan and is surrounded by an edge bead 19. The the edge bead 19 prevents that the collected condensed water can flow out from the pan 13. The drip pan 13 is provided with an outflow opening 14. The the opening is positioned in the lowermost plane of the drip pan 13, in order to achieve unimpeded running out of the condensed water on the basis of the action of gravity. An outflow hose 15 is arranged at the the opening 14 which is preferably configured as a bore or an outflow connector, which outflow hose 15 enables drainage of the condensed water through the aircraft floor 21 to a drainage collecting tank (not shown). It is also possible that an interface to the drainage system which is present in the aircraft is provided via a drain mast or a waste water system. The drip pan 13 can be fastened by way of suitable fastening of the trough to the water outlet, for example to the outflow plug. Further possibilities are the direct fixing on the aircraft floor and/or also sealing with silicone around the pan 13, which sealing at the same time fulfils a fixing function. The fixing of the drip pan 13 in the stowage space 3 can also take place as an alternative to or in combination with customarily known releasable fastening methods by way of corresponding capabilities of a skilled person in the art.

[0038] FIG. 5 shows the drip pan 13 as a separate component in a perspective illustration. The profile of the the drip pan 13 and its positioning on the aircraft floor 21 can be seen clearly in the side view in FIG. 6. As has already been mentioned in the description of the figures with respect to FIG. 4, the outflow opening or the outflow connector 14 is connected to a drainage system by an outflow hose 15. For this purpose, an opening 22 is made in the aircraft floor 21, which opening 22 makes it possible to lead through the outflow hose 15. Furthermore, it can be seen clearly in FIG. 6 that the drip pan 13 comprises, as main portion, the collecting portion 17 which is slightly inclined and forms a drainage surface for the collected condensed water to the outflow 14. The floor boundary portion 16 is provided as an edge at the front rim region of the drainage portion 17, which floor boundary portion 16 is seated on the aircraft floor 21 and, by way of its shape and curvature, defines the height and inclination of the collecting portion 17. The rear rim region is configured as an edge or transition portion 18 to the rear seal 8. It can be seen that the edge or the transition portion 18 is bent upwards, in order to realize a sealing and/or dimensionally adapted effect with the rear seal 8. The collecting portion 17 is surrounded by an edge bead 19. The the edge bead 19 prevents that the collected condensed water can flow out from the pan 13 over the pan edge. The outflow of the condensed water from the drip pan 13 takes place via the outflow opening 14 and the outflow hose 15 which is connected to it. Customary connections can be used here. Releasable connections are advantageous, such as screw connections or plug-in connections, for example.

[0039] FIG. 7 shows a passenger aircraft 20. Here, a galley 1 according to the disclosure herein is arranged in the passenger cabin, for example in the region of the front access door 23.
