Abstract

A galley cart includes walls defining an interior cavity extending between a front and a rear of the galley cart and the interior cavity extending between a top end and a bottom end. A supply port is provided in flow communication with the interior cavity at or near either the top end or the bottom end of the cart. A return port is provided in flow communication with the interior cavity that is adjacent the supply port at or near the top end or the bottom end of the cart. A barrier is positioned between the supply port and the return port within the interior cavity of the cart to define a supply chamber and a return chamber to control airflow through the interior cavity.

First claim

What is claimed is:

1. A galley comprising:
a rear wall;
a mid-wall oriented with respect to the rear wall;
a cart compartment at least partially defined by the rear wall and the mid-wall, the cart compartment being configured to receive at least one galley cart;
a first duct defined in the rear wall below the mid-wall and in flow communication with the cart compartment; and
a second duct defined in the rear wall adjacent the first duct and in flow communication with the cart compartment;
wherein the rear wall below the mid-wall is jogged inward relative to the position of the rear wall above the mid-wall such that the rear wall is non-planar.

2. The galley of claim 1 , wherein a bottom of the rear wall below the mid-wall is jogged inward to reduce a width of the cart compartment at the bottom compared to at the mid-wall.

3. The galley of claim 1 , wherein the first and second ducts are positioned near the mid-wall, the rear wall being jogged inward below the first and second ducts to reduce a width of the cart compartment below the first and second ducts.

4. The galley of claim 1 , wherein the first and second ducts are positioned at or near a bottom of the rear wall, the rear wall being jogged inward above the first and second ducts to reduce a width of the cart compartment.

5. The galley of claim 1 , wherein the first and second ducts are positioned side-by-side at a common vertical height along the rear wall.

6. The galley of claim 1 , further comprising a supply duct and a return duct in the rear wall above the first and second ducts, the supply duct being in flow communication with either the first duct or the second duct, the return duct being in flow communication with the other of the first duct or the second duct, the rear wall along the supply and return ducts and along the first and second ducts defining an upper rear wall, the rear wall below the supply and return ducts and below the first and second ducts defining a lower rear wall, the lower rear wall being forward of the upper rear wall.

7. The galley of claim 1 , further comprising a galley cart received in the cart compartment, the galley cart comprising walls defining an interior cavity, the interior cavity extending between a top end and a bottom end, a supply port in flow communication with the interior cavity at the top end and a return port in flow communication with the interior cavity at the top end, the galley cart comprising a barrier positioned between the supply port and the return port within the interior cavity of the cart, wherein the supply port is in flow communication with the first duct and the return port is in flow communication with the second duct, the barrier controlling airflow through the interior cavity between the supply and return ports.

8. A galley comprising:
a rear wall;
a mid-wall oriented with respect to the rear wall;
a cart compartment at least partially defined by the rear wall and the mid-wall, the cart compartment being configured to receive at least one galley cart;
a first duct defined in the rear wall below the mid-wall and in flow communication with the cart compartment;
a second duct defined in the rear wall adjacent the first duct and in flow communication with the cart compartment; and
a galley cart received in the cart compartment, the galley cart comprising walls defining an interior cavity, the interior cavity extending between a top end and a bottom end, a supply port in flow communication with the interior cavity at or near the top end and a return port in flow communication with the interior cavity adjacent the supply port at or near the top end, the galley cart comprising a barrier positioned between the supply port and the return port within the interior cavity of the cart, wherein the supply port is in flow communication with the first duct and the return port is in flow communication with the second duct, the barrier controlling airflow through the interior cavity between the supply and return ports.

9. The galley of claim 8 , wherein the supply port and the return port are vertically stacked immediately adjacent each other along the rear of the galley cart with the barrier extending from the rear at a location between the supply port and the return port.

10. The galley of claim 8 , wherein the barrier forces airflow through the entire interior cavity between the supply port and the return port.

11. The galley of claim 2 , wherein the barrier includes a horizontal barrier extending horizontally at least partially between the rear and the front of the galley cart and a vertical barrier extending vertically at least partially between the top end and the bottom end.

12. The galley of claim 2 , wherein the barrier extends from the rear into the interior cavity.

13. The galley of claim 2 , wherein the barrier extends from the top end into the interior cavity.

14. The galley of claim 2 , wherein the barrier is movable within the interior cavity.

15. The galley of claim 2 , wherein the barrier is approximately centered between the front and the rear allowing space for a tray to be positioned in the interior cavity forward of the barrier and allowing space for a tray to be positioned in the interior cavity rearward of the barrier.

16. The galley of claim 8 , wherein at least one of the supply port and the return port are provided proximate to the top end.

17. The galley of claim 8 , wherein at least one of the supply port and the return port are provided proximate to the bottom end.

18. The galley of claim 8 , wherein at least one of the supply port and the return port are provided in a rear wall at the rear of the galley cart.

19. The galley of claim 8 , wherein the supply chamber is positioned above the return chamber extending along the top end and the supply chamber is positioned forward of the return chamber at the front, and wherein the return chamber is positioned below the supply chamber extending along the bottom end and the return chamber is positioned rearward of the supply chamber at the rear.

20. The galley of claim 8 , wherein the return chamber is positioned above the supply chamber extending along the top end and the return chamber is positioned forward of the supply chamber at the front, and wherein the supply chamber is positioned below the return chamber extending along the bottom end and the supply chamber is positioned rearward of the return chamber at the rear.

21. The galley of claim 8 , wherein supply port is an upper supply port and the return port is an upper return port, the galley cart further comprising a lower supply port at or near the bottom end and a lower return port at or near the bottom end.

22. The galley of claim 8 , wherein the rear wall below the mid-wall is jogged inward relative to the position of the rear wall above the mid-wall such that the rear wall is non-planar.

23. The galley of claim 8 , wherein the first and second ducts are positioned near the mid-wall, the rear wall being jogged inward below the first and second ducts to reduce a width of the cart compartment below the first and second ducts.

24. The galley of claim 8 , wherein the first duct and the second duct are both positioned at the rear wall and are both positioned at the mid-wall.
