Abstract

A food warming apparatus includes a heating compartment that can hold one or more trays containing previously cooked food portions. A rack in the heating compartment includes a support member, a channel, and a stop that blocks the front end of the channel. A cover that includes a horizontal section and a vertical section is mounted on the support such that the horizontal section is supported on one side by the support member and on the other side by the vertical section, which is positioned in the channel behind the stop. When a tray is inserted into the receiving space defined by the cover and support member, the cover is lifted up so that the horizontal section rests on the tray and at least partially blocks the open top of the tray, thereby restricting evaporation of liquids from the previously cooked food portions contained in the tray.

Claims

1. A food warming apparatus for maintaining previously cooked food portions contained in at least one tray in a ready-to-use condition, said at least one tray having a lip defining a tray opening, said food warming apparatus comprising:

a cabinet having at least one heating compartment therein;

at least one support member disposed in said at least one heating compartment; and

a cover removably mounted on said at least one support member, said cover having a horizontal section and a single vertical section extending downwardly from said horizontal section, said horizontal section being supported on a first side by said single vertical section and being supported on a second side by said at least one support member,

said cover and said at least one support member cooperatively defining at least one receiving space for receiving said at least one tray.

2. The food warming apparatus of claim 1, wherein said cover is movable between a first position, in which said horizontal section rests on said at least one support member, and a second position, in which said horizontal section rests on said lip of said at least one tray.

3. The food warming apparatus of claim 2, wherein in said second position, said horizontal section of said cover at least partially blocks said tray opening so as to restrict evaporation of liquid from said previously cooked food portions contained in said at least one tray.

4. The food warming apparatus of claim 3, wherein said cover is configured to move from said first position to said second position when said at least one tray is inserted into said at least one receiving space, and wherein said cover is configured to move from said second position to said first position when said at least one tray is removed.

5. The food warming apparatus of claim 4, further comprising:

at least one stop that retains said cover in said at least one heating compartment when said at least one tray is removed.

6. The food warming apparatus of claim 5, further comprising:

a plurality of channel members defining a channel in which said single vertical section is disposed, said channel having a front end and a back end.

7. The food warming apparatus of claim 6, wherein said at least one stop blocks at least said front end of said channel.

8. The food warming apparatus of claim 7, further comprising:

a frame disposed in said at least one heating compartment, said at least one support member extending upwardly from said frame.

9. The food warming apparatus of claim 8, wherein said at least one support member comprises a bracket extending between a front of said frame and a back of said frame.

10. The food warming apparatus of claim 1, further comprising:

an additional cover removably mounted on said at least one support member, said additional cover having a horizontal section and a single vertical section, and wherein said at least one support member comprises a first support member supporting said horizontal section of said cover and a second support member supporting said horizontal section of said additional cover.

11. The food warming apparatus of claim 10, further comprising:

a plurality of channel members defining a first channel and a second channel between said first and second support members, said single vertical section of said cover being disposed in said first channel and said single vertical section of said additional cover being disposed in said second channel.

12. The food warming apparatus of claim 1, wherein said cover is metal.

13. The food warming apparatus of claim 1, further comprising at least one heater plate for heating said at least one heating compartment.
