Abstract

A cabinet is provided. The cabinet is configured to receive and support a plurality of trays therein. The cabinet includes a housing defining an enclosure with a top, a bottom, and right and left sides disposed between the top and bottom and a plurality of shelves disposed within the enclosure and disposed between the right and left sides in a spaced relationship. One or more heaters are disposed in conjunction with each of the plurality of shelves. A cover is disposed directly below at least some of the plurality of shelves, and configured to be slidably connected with respect to the shelf for selective placement into the enclosure or removal from the shelf. A control system is in electrical communication with the one or more heaters, and is configured to operate the one or more heaters in a predetermined manner.

Claims

1. A cabinet configured to receive and support a plurality of trays comprising:

a housing defining an enclosure with top, bottom, right, and left walls;

a plurality of racks disposed within the housing in a vertically spaced arrangement; and

a plurality of heaters disposed in conjunction with the plurality of racks, with at least one of the plurality of heaters being disposed in conjunction with each of the plurality of racks;

the plurality of heaters being configured to operate on a duty cycle to maintain the racks within a specified desired temperature range.

2. The cabinet of claim 1, further comprising a plurality of planar elongate sheets slidably mounted within the housing, wherein each of the plurality of sheets are received proximate one of the plurality of racks.

3. The cabinet of claim 2, wherein each of the sheets in combination with a rack disposed directly below the respective sheet are configured to define a holding volume, wherein the holding volume is sized to closely receive a conventional restaurant pan therebetween.

4. The cabinet of claim 3, wherein each of the sheets are configured to contact a plurality of top edges of the pan disposed thereunder and substantially enclose an inner volume of the pan.

5. The cabinet of claim 4, wherein the pan is removable from the holding volume when in contact with the sheet directly above the pan.

6. The cabinet of claim 4, wherein the sheet is removable from the holding volume when in contact with the pan disposed directly below the sheet.

7. The cabinet of claim 1, wherein the plurality of heaters each are controlled by an infinite switch.

8. The cabinet of claim 1, wherein the plurality of racks comprise a plurality of planar members that enclose the respective heater disposed in conjunction with the respective rack.

9. The cabinet of claim 7, wherein the plurality of heaters are organized into a plurality of pairs of heaters with a single infinite switch controlling a respective pair of heaters.

10. A cabinet configured to receive and support a plurality of trays therein, comprising:

a housing defining an enclosure with a top, a bottom, and right and left sides disposed between the top and bottom;

a plurality of shelves disposed within the enclosure and disposed between the right and left sides in a spaced relationship;

one or more heaters disposed in conjunction with each of the plurality of shelves;

a cover disposed directly below at least some of the plurality of shelves, and configured to be slidably connected with respect to the shelf for selective placement into the enclosure or removal from the shelf; and

a control system in electrical communication with the one or more heaters, configured to operate the one or more heaters in a predetermined manner.

11. The cabinet of claim 10, wherein the control system is configured to selectively operate the one or more heaters to maintain a specified steady state temperature within the enclosure.

12. The cabinet of claim 10, wherein the control system is configured to selectively operate the one or more heaters to provide a constant heat output from the one or more heaters.

13. A cabinet configured to receive and support a plurality of trays therein, comprising:

a housing defining an enclosure with a top, a bottom, and right and left sides disposed between the top and bottom with substantially open front and back sides of the enclosure;

a plurality of shelves disposed within the enclosure and disposed between the right and left sides in a spaced relationship;

one or more heaters disposed in conjunction with each of the plurality of shelves;

a cover disposed directly below at least some of the plurality of shelves, and configured to be slidably connected the housing for selective placement into the enclosure or removal from the shelf; and

a control system in electrical communication with the one or more heaters, configured to operate the one or more heaters in a predetermined manner.

14. The cabinet of claim 13, wherein the cover is slidably connected to the respective shelf.
