Abstract

A food warming apparatus is provided with a cabinet defining a food treatment space and a food storage space above the food treatment space and in communication therewith. A wall at the bottom of the food treatment space supports a supply of food. Structure is provided to gain access to the food storage space to introduce a food supply and separate structure is provided to gain access to the food in the food treatment space for removal of the treated food. Heat is directed in a circulating path upwardly through food at one portion of the treatment space and downwardly through food in another portion of the treatment space.

Claims

1. A food warming apparatus comprising:

a cabinet defining a food treatment space and a food storage space above said food treatment space and in communication therewith;

means at the bottom of the food treatment space for supporting food in the food treatment space;

means for directing heated air in a circulating path upwardly through food in one portion of the treatment space and downwardly through food in another portion of the treatment space;

first means for gaining access to the food storage space to introduce food therein; and

second means below said first means for gaining access to said food treatment space to permit removal of food therein.

2. The food warming apparatus according to claim 1 wherein said cabinet is configured so that there is an unobstructed vertical path between the food treatment space and the food storage space so that food introduced to the food storage space falls by gravity into the food treatment space.

3. The food warming apparatus according to claim 1 wherein said food supporting means comprises a peforate bottom wall.

4. The food warming apparatus according to claim 3 further including means for heating air and a fan for moving air in said circulating path to said heating means and through the perforate bottom wall.

5. The food warming apparatus according to claim 3 including means to removably mount the perforate bottom wall in the food treatment space to facilitate cleaning.

6. The food warming apparatus according to claim 3 wherein a crumb collecting tray is provided beneath said bottom wall and means are provided to removably install the crumb collecting tray adjacent the bottom of the food treatment space.

7. The food warming apparatus according to claim 3 wherein said cabinet has a front side and a back side, the second means is adjacent the front of the cabinet and means mount the bottom wall so that the bottom wall declines from the back side to the front side of the cabinet to accumulate food adjacent the second means so that food is gravitationally displaced proximate said second means to facilitate ready access to the food in the treatment space.

8. The food warming apparatus according to claim 3 wherein the food treatment space and food storage space are in at least partial vertical alignment and baffle means is provided in one of said food treatment and food storage spaces to break the fall of food from said food storage space to said bottom wall.

9. The food warming apparatus according to claim 1 wherein said second means comprises an opening in the cabinet, a door with a flat face and means mounting the door to the cabinet for pivoting movement between a closed position wherein the door closes the cabinet opening and an open position wherein the flat door face is substantially horizontally situated so as to function as a work shelf adjacent said second means.

10. A food warming apparatus comprising:

a cabinet having a front side and a rear side and defining a food storage space and a food treatment space below and in communication with the food storage space;

a perforate wall at the bottom of the food treatment space for supporting food in the food treatment space;

means for supporting the bottom wall so that the bottom wall declines from the rear side towards the front side of the cabinet to thereby cause food introduced to the food treatment space to accumulate at the front side of the cabinet;

first means for gaining access to the food storage space to introduce food therein;

second means below said first means for gaining access to said food treatment space to permit removal of food therefrom;

a source of heated air; and

means for directing air in a circulating path laterally beneath the bottom wall upwardly through the bottom wall and food in the food treatment space and downwardly through food in the food treatment space and the bottom wall for redirection laterally beneath the bottom wall.

11. The food warming apparatus according to claim 10 wherein said source of heated air comprises a heater element and a fan for directing air against the heater element.

12. The food warming apparatus according to claim 10 wherein means removably mount the bottom wall in the food treatment space to facilitate cleaning.

13. The food warming apparatus according to claim 10 including a crumb collecting tray and means removably mount the crumb collecting tray beneath the bottom wall.

14. The food warming apparatus according to claim 10 including a fan with a blade and wherein said air directing means includes a deflector beneath the bottom wall, said deflector defining a space for the fan blade and having a solid wall above the fan and horizontally spaced vertically extending perforate walls, said solid wall causing air moved upwardly by the fan to be deflected through said perforate walls, and means are provided for developing suction upon said fan being operated and for thereby drawing air from the food treatment space into the space for the fan blades and against the fan blades to be thereafter moved by the fan blades through said vertically extending perforate walls.

15. The food warming apparatus according to claim 14 wherein said cabinet has a wall adjacent the front of the cabinet and above the bottom wall that inclines from the front side of the cabinet to the rear side of the cabinet to deflect circulating air in the food treatment space downwardly to be picked up by the suction developing means.

16. The food warming apparatus according to claim 10 wherein a baffle is mounted in one of the food storage space and food treatment space to deflect incoming food from the food storage space delivered through the first means to prevent unobstructed passage of incoming food against the bottom wall.
