MULTIPLE TIER HOLDING DISPLAY AND METHOD

1 . A food display cabinet comprising:

a plurality of walls that define a food holding compartment;

a ductwork disposed in fluid communication with said food holding compartment;

a reservoir that holds water disposed in said ductwork;

a heating element disposed to heat said water to provide moisture above the water; and

a fan disposed in said ductwork that provides a circulating airflow laden with said moisture between said ductwork and said food holding compartment.

2 . The food display cabinet of claim 1 , wherein said ductwork comprises a first duct that distributes said airflow laden with moisture evenly throughout said food holding compartment.

3 . The food display cabinet of claim 2 , wherein said ductwork comprises a second duct that is disposed below a bottom wall of said plurality of walls and wherein said fan and water reservoir are disposed in said second duct.

4 . The food display cabinet of claim 3 , wherein said ductwork comprises a third duct that extends lengthwise across an edge of said bottom wall and that comprises a plurality of apertures disposed to take in said circulating airflow.

5 . A food display cabinet comprising:

a plurality of walls that define at least one food holding tier; and

a plurality of light emitting diodes that is disposed in an arrangement to illuminate said food holding tier.

6 . The food holding display cabinet of claim 5 , wherein said arrangement comprises at least one row of said light emitting diodes.

7 . The food holding display cabinet of claim 6 , further comprising: a plurality of shelves that together with said plurality of walls define multiple tiers, which include said at least one food holding tier; and wherein said plurality of light emitting diodes is disposed in a plurality of arrangements, one for each tier.

8 . The food holding cabinet of claim 5 , wherein said arrangement of light emitting diodes is disposed in a holder, which is positioned so that light emitted by said light emitting diodes is directed inwardly and downwardly into said food holding tier.

9 . A food display cabinet comprising:

at least one shelf; and

an arrangement of one or more heating elements disposed to heat first and second heating zones of said shelf so that said first heating zone is warmer than said second heating zone.

10 . The food display cabinet of claim 9 , wherein said first heating zone and said second heating zone are adjacent a front edge and a back edge, respectively, of said shelf.

11 . The food display cabinet of claim 9 , wherein said arrangement comprises a serpentine winding of at least one of said heating elements in at least one of said first and second heating zones.

12 . The food display cabinet of claim 9 , wherein said arrangement comprises a first and a second heating element of said plurality of heating elements, wherein said first and second heating elements are arranged in first and second serpentine windings in said first and second heating zones, and wherein said first serpentine winding has more turns than the second serpentine winding.

13 . A method for injecting moisture into a food holding compartment defined by a plurality of walls comprising:

providing a ductwork in fluid communication with said food holding compartment;

disposing a reservoir in said ductwork;

heating water in said reservoir to form moisture above the water; and

circulating an airflow laden with said moisture between said ductwork and said food holding compartment.

14 . The method of claim 13 , wherein said ductwork comprises a first duct that distributes said airflow laden with moisture evenly throughout said food holding compartment.

15 . The method of claim 14 , wherein said ductwork comprises a second duct that is disposed below a bottom wall of said plurality of walls and wherein said reservoir is disposed in said second duct.

16 . The method of claim 15 , wherein said ductwork comprises a third duct that extends lengthwise across an edge of said bottom wall and that comprises a plurality of apertures disposed to take in said circulating airflow.

17 . A method of illuminating a food display cabinet comprising:

forming a food holding tier in said food display cabinet; and

disposing a plurality of light emitting diodes in an arrangement to illuminate said food holding tier.

18 . The method of claim 17 , wherein said arrangement comprises at least one row of said light emitting diodes.

19 . The method of claim 18 , further comprising:

providing a plurality of shelves that together with said plurality of walls define multiple tiers, which include said at least one food holding tier; and

disposing said plurality of light emitting diodes in a plurality of arrangements, one for each of said food holding tiers.

20 . The method of claim 17 , further comprising:

disposing said arrangement of light emitting diodes in a holder; and

positioning said holder so that light emitted by said light emitting diodes is directed inwardly and downwardly into said food holding tier.

21 . A method for forming a food display cabinet comprising:

providing at least one shelf; and

disposing an arrangement of one or more heating elements to heat first and second heating zones of said shelf so that said first heating zone is warmer than said second heating zone.

22 . The method of claim 21 , further comprising:

positioning said first heating zone and said second heating zone adjacent a front edge and a back edge, respectively, of said shelf.

23 . The method of claim 21 , further comprising:

forming said arrangement with a serpentine winding of at least one of said heating elements in at least one of said first and second heating zones.

24 . The method of claim 21 , further comprising:

forming said arrangement with a first and a second heating element of said plurality of heating elements, wherein said first and second heating elements are arranged in first and second serpentine windings in said first and second heating zones, and wherein said first serpentine winding has more turns than the second serpentine winding.
