Abstract

A waste compaction system for a vehicle includes a moveable trolley for storing waste, and a docking station integratable into a cabin monument for inserting the trolley. The trolley includes a housing having an opening for inserting waste, a vacuum waste compacting mechanism inside the housing and a first suction port accessible from outside the housing, the first suction port being couplable with the vacuum waste compacting mechanism. The docking station and the trolley are adapted to each other such that the trolley is engageable with the docking station, and wherein the docking station includes a second suction port couplable with a suction line in the vehicle and the first suction port. Resultantly, a lightweight and efficient waste compaction system is provided, which allows moving the trolley for collecting waste inside a cabin of the vehicle.

First claim

The invention claimed is:

1. A waste compaction system for a vehicle, the system comprising:
a moveable trolley for storing waste; and
a docking station integratable into a cabin monument for inserting the trolley;
wherein the trolley comprises a housing having an opening for inserting waste, at least one vacuum waste compacting mechanism inside the housing and a first suction port accessible from outside the housing, the first suction port being coublable with the at least one vacuum waste compacting mechanism,
wherein the docking station and the trolley are adapted to each other such that the trolley is engageable with the docking station,
wherein the docking station comprises a second suction port couplable with a suction line in the vehicle and the first suction port,
wherein the at least one vacuum waste compacting mechanism comprises a compaction sleeve extending from a bottom of the trolley housing to a movable upper frame facing to the opening of the trolley,
wherein the trolley further comprises a ventilation frame which is insertable into an interior area section of the movable upper frame, and
wherein the ventilation frame comprises ventilation openings and is adapted for holding a waste bag such that the waste bag is enclosed by the compaction sleeve, and for providing air exchange between the waste bag and a volume enclosed by the compaction sleeve.

2. The waste compaction system of claim 1 , wherein the first suction port is coupled with the interior of the compaction sleeve through an opening in at least one of the compaction sleeve and a bottom of the trolley.

3. The waste compaction system of claim 1 ,
wherein the compaction sleeve comprises first and second flat, rigid plates integrated into first and second lateral surfaces of the compaction sleeve, and
wherein the first and second plates are dimensioned such that by evacuating the compaction sleeve the first and second plates approach each other substantially parallelly.

4. The waste compaction system of claim 1 , wherein the opening of the trolley housing is positioned in the movable upper frame.

5. The waste compaction system of claim 1 , wherein the upper frame is lockable in at least one position.

6. The waste compaction system of claim 1 , wherein a cover plate is placeable on the opening in a sealing manner.

7. The waste compaction system of claim 1 , wherein the first suction port comprises an interface means adapted for selectively coupling and decoupling the first suction port and the second suction port, when the trolley engages the docking station.

8. The waste compaction system of claim 1 , wherein the docking station is a receiving space having at least first and second delimiting walls, wherein one of the at least first and second delimiting walls carries the second suction port.

9. The waste compaction system of claim 8 , wherein at least one of the at least first and second delimiting walls comprises at least one guide means for aligning the trolley in the receiving space.

10. The waste compaction system of claim 1 , wherein the trolley comprises a drainage means for disposing of liquids, which are contained in the waste and accumulate in a bottom region of the trolley due to compaction of waste, into the suction line.

11. A cabin monument comprising a suction line and a waste compaction system comprising:
a moveable trolley for storing waste; and
a docking station integratable into a cabin monument for inserting the trolley;
wherein the trolley comprises a housing having an opening for inserting waste, at least one vacuum waste compacting mechanism inside the housing and a first suction port accessible from outside the housing, the first suction port being coublable with the at least one vacuum waste compacting mechanism,
wherein the docking station and the trolley are adapted to each other such that the trolley is engageable with the docking station,
wherein the docking station comprises a second suction port couplable with a suction line in the vehicle and the first suction port,
wherein the at least one vacuum waste compacting mechanism comprises a compaction sleeve extending from a bottom of the trolley housing to a movable upper frame facing to the opening of the trolley,
wherein the trolley further comprises a ventilation frame which is insertable into an interior area section of the movable upper frame, and
wherein the ventilation frame comprises ventilation openings and is adapted for holding a waste bag such that the waste bag is enclosed by the compaction sleeve, and for providing air exchange between the waste bag and a volume enclosed by the compaction sleeve.

12. The cabin monument of claim 11 , wherein the cabin monument comprises at least one lavatory unit coupled with the suction line.

13. An aircraft, comprising a vacuum system having a suction line, the aircraft further comprising a waste compaction system and a cabin monument into which the suction line extends, the waste compaction system comprising:
a moveable trolley for storing waste; and
a docking station integratable into a cabin monument for inserting the trolley;
wherein the trolley comprises a housing having an opening for inserting waste, at least one vacuum waste compacting mechanism inside the housing and a first suction port accessible from outside the housing, the first suction port being coublable with the at least one vacuum waste compacting mechanism,
wherein the docking station and the trolley are adapted to each other such that the trolley is engageable with the docking station,
wherein the docking station comprises a second suction port couplable with a suction line in the vehicle and the first suction port,
wherein the at least one vacuum waste compacting mechanism comprises a compaction sleeve extending from a bottom of the trolley housing to a movable upper frame facing to the opening of the trolley,
wherein the trolley further comprises a ventilation frame which is insertable into an interior area section of the movable upper frame, and
wherein the ventilation frame comprises ventilation openings and is adapted for holding a waste bag such that the waste bag is enclosed by the compaction sleeve, and for providing air exchange between the waste bag and a volume enclosed by the compaction sleeve.
