Heated cabinet for food

Claim 2

A cabinet for holding heated food comprising: a housing defining an interior; blower means for circulating air within said interior, coupled to said housing; heater means coupled to said housing for heating said circulating air; and closed air distribution means, for directing heated air from said blower means past food in said interior, said distribution means including at least one inlet plenum communicating with said blower means and having a plurality of graduated openings for distributing heated air into said interior, said openings being graduated such that the area defined by said openings increases with increased distance from said blower means; whereby an even distribution of heated air throughout said interior of said cabinet is achieved assuring that all the food in said cabinet is maintained uniformly heated.

Claim 3

The cabinet defined by claim 1 wherein said housing includes a pair of parallel, spaced-apart side walls interconnected by a door panel.

Claim 4

The cabinet defined by claim 2 wherein said inlet plenum is disposed on one of said side walls, and wherein an exhaust plenum for removing air from said interior and communicating with the input of said blower means is disposed on the other of said side walls, such that air flows from side-to-side in said interior of said cabinet.

Claim 5

The cabinet defined by claim 3 wherein said air distribution means comprises a first louvered panel spaced-apart from said one side wall so as to define said inlet plenum, and wherein said exhaust plenum includes a second louvered panel spaced apart from said other side wall.

Claim 6

The cabinet defined by claim 4 wherein said first and second louvered panels include support means extending into said interior for supporting food pans.

Claim 7

The cabinet defined by claim 1 wherein said heater means and blower means are mounted on the top of said housing.

Claim 8

The cabinet defined by claim 6 including a water reservoir disposed adjacent to the path of said circulating air to permit moisture to be added to said air.

Claim 9

A cabinet for holding heated food comprising: a housing defining an interior; blower means for circulating air within said interior coupled to said housing; heater means coupled to said housing for heating said circulating air; air distribution means for directing heated air from said blower means past food in said interior; a water reservoir removably mounted along the path of said circulating air for allowing moisture to be added to said air; and, at least one baffle member disposed within said water reservoir to vary the area of said water surface in contact with said circulating air, said baffle member including generally vertical legs for retarding movement of water within said reservoir, and a member coupled to said legs for covering the water surface in said reservoir when in a first position, and for allowing said water surface to contact said circulating air when in a second position; whereby the amount of moisture in said circulating air may be varied by positioning said baffle member within said reservoir.

Claim 10

A cabinet for holding heated food comprising: a housing defining an interior; blower means for circulating air within said interior coupled to said housing; heater means coupled to said housing for heating said circulating air; air distribution means for directing heated air from said blower means past food in said interior; a water reservoir removably mounted along the path of said circulating air for allowing moisture to be added to said air; and, at least one baffle member disposed within said water reservoir to vary the area of said water surface in contact with said circulating air, said baffle member including generally vertical legs for retarding movement of water within said reservoir, and a member coupled to said legs for covering the water surface in said reservoir when in a first position, and for allowing said water surface to contact said circulating air when in a second position; whereby the amount of moisture in said circulating air may be varied by positioning said baffle member within said reservoir.

Claim 11

A cabinet for holding heated food comprising: a housing defining an interior; blower means for circulating air within said interior, coupled to said housing; heater means coupled to said housing for heating said circulating air; air distribution means for directing heated air from said blower means past food in said interior; a water reservoir removably mounted along the path of said circulating air for allowing moisture to be added to said air; at least one channel shaped baffle member disposed within said water reservoir, said baffle member including generally vertical flanges for retarding movement of water within said reservoir, and a web coupled to said flanges and supported above the water surface by said flanges for covering said water surface in said reservoir when in a first position, and for allowing said water surface to contact said circulating air when in a second position; whereby the amount of moisture in said circulating air may be varied by positioning said baffle member within said reservoir.

Claim 12

A cabinet for holding heated food comprising: a housing defining an interior; blower means for circulating air within said interior, coupled to said housing; heater means coupled to said housing for heating said circulating air; air distribution means for directing heated air from said blower means past food in said interior; a water reservoir removably mounted along the path of said circulating air for allowing moisture to be added to said air; at least one channel shaped baffle member disposed within said water reservoir, said baffle member including generally vertical flanges for retarding movement of water within said reservoir, and a web coupled to said flanges and supported above the water surface by said flanges for covering said water surface in said reservoir when in a first position, and for allowing said water surface to contact said circulating air when in a second position; whereby the amount of moisture in said circulating air may be varied by positioning said baffle member within said reservoir.

Claim 13

The cabinet defined by claim 9 wherein said air distribution means includes a plurality of graduated openings for distributing heated air into said interior, said opening being graduated such that said openings increase with increased distance from said blower means.

Claim 14

The cabinet defined by claim 9 wherein said blower means and heater means are mounted on the top of said housing.
