A forced air cooler ( 10 ) includes a cabinet ( 20 ) defining a lower chamber ( 30 ) wherein product is stored and an upper chamber ( 40 ) housing a pair of fans ( 62 ) and ( 64 ) positioned intermediate spaced evaporators ( 52 ) and ( 54 ). A wire rack ( 90 ) disposed on the floor of the cabinet (
A forced air cooler ( 10 ) includes a cabinet ( 20 ) defining a lower chamber ( 30 ) wherein product is stored and an upper chamber ( 40 ) housing a pair of fans ( 62 ) and ( 64 ) positioned intermediate spaced evaporators ( 52 ) and ( 54 ). A wire rack ( 90 ) disposed on the floor of the cabinet ( 20 ) supports the product off the floor and includes integral side fences ( 94 ) and ( 96 ) which serve to space the product away from the side walls ( 26 ) and ( 28 ) of the cabinet. The fans ( 62 ) and ( 64 ) draw air through the evaporators ( 52 ) and ( 54 ), respectively, and direct the cooing air through the openings provided by the slots ( 68 ) in the diffuser plate ( 66 ) to provide a uniformly distributed flow of cooling air, at its coolest condition, downwardly into the lower chamber ( 30 ) to pass over the product stored therein. Upon reaching the floor of the lower chamber, the cooling airflow passes along the surface of the floor and is drawn into the lower return air duct ( 70 ) and thence into side air ducts ( 76 ) and ( 78 ) to return to the upper chamber ( 40 ) and be again drawn through the evaporators ( 52 ) and ( 54 ).

1. A cooler comprising:a cabinet having a front wall, a back wall, first and second longitudinally spaced side walls, a insulated floor panel and a insulated top panel cooperatively defining a lower chamber for housing articles to be cooled and an upper chamber disposed superadjacent said lower chamber;a generally horizontally disposed diffuser plate positioned between said lower chamber and said upper chamber, said diffuser plate having a plurality of openings passing therethrough;at least one evaporator for cooling air passing therethrough, said at least one evaporator disposed within said upper chamber;at least one air circulator disposed within said upper chamber in operative association with said at least one evaporator for generating a flow of cooling air passing through said at least one evaporator;first and second generally vertically extending air return ducts, each having an inlet opening superadjacent said floor and an outlet opening into said upper chamber, said first air return duct lying along side first side wall and said second air return duct lying along said second side wall;a lower return air duct defining a bottom airflow passage lying superadjacent said floor and extending beneath the articles housed within said lower chamber, said lower air return duct having a generally horizontal, longitudinally extending base disposed in spaced relationship with and above said floor of said chamber, said bottom airflow passage in flow communication with each of said air return duct, anda first doored self-service access opening into said lower chamber from the front side of said cooler and a second doored self service access opening into said lower chamber from the back side of said cooler. 2. A cooler as recited in claim 1 wherein said at least one evaporator comprises a pair of evaporators disposed within said upper chamber in longitudinally spaced relationship at opposite ends of said upper chamber and said at least one air circulator is disposed between said longitudinally spaced evaporators. 3. A cooler as recited in claim 2 wherein said at least one air circulator comprises an axial flow fan. 4. A cooler as recited in claim 2 wherein said at least one air circulator comprises a pair of longitudinally spaced axial flow fans. 5. A cooler as recited in claim 1 wherein the plurality of openings passing through the diffuser plate comprise a plurality of longitudinally spaced, traversely extending slots. 6. A cooler as recited in claim 1 further comprising a support grate positioned superadjacent said floor, said grate supporting the articles housed within said lower chamber above said floor and establishing the bottom airflow passage. 7. A cooler as recited in claim 6 wherein said support grate comprises a horizontally extending wire framework base, a front fence extending generally vertically upwardly from a front edge of the base and an aft fence extending generally vertically from a back edge of the base, said wire framework base being relatively open to airflow therethrough. 8. A cooler comprisinga cabinet having a front wall, a back wall, first and second longitudinally spaced side walls, a insulated floor panel and a insulated top panel cooperatively defining a lower chamber for housing articles to be cooled and an upper chamber disposed superadjacent said lower chamber;a generally horizontally disposed diffuser plate positioned between said lower chamber and said upper chamber, said diffuser plate having a plurality of openings passing therethrough;at least one evaporator for cooling air passing therethrough, said at least one evaporator disposed within said upper chamber;at least one air circulator disposed within said upper chamber in operative association with said at least one evaporator for generating a flow of cooling air passing through said at least one evaporator;at least one generally vertically extending air return duct having an inlet opening superadjacent said floor and an outlet opening into said upper chamber; anda lower air return duct defining a bottom airflow passage lying superadjacent said floor and extending beneath the articles housed within said lower chamber, said lower air return duct having a generally horizontal, longitudinally extending base disposed in spaced relationship with and above said floor of said chamber and at least one side flange extending generally vertically downwardly therefrom to said floor of said chamber, said at least one side flange being perforated with a plurality of holes in flow communication with said at least one air return duct. 9. A cooler for storing cartons of drink in a chilled state for customer self service comprisinga cabinet having a front wall, a back wall, first and second longitudinally spaced side walls, a insulated floor panel and a insulated top panel cooperatively defining a lower chamber for housing articles to be cooled and an upper chamber disposed superadjacent said lower chamber;a generally horizontally disposed diffuser plate positioned between said lower chamber and said upper chamber, said diffuser plate having a plurality of openings passing therethrough;at least one evaporator for cooling air passing therethrough, said at least one evaporator disposed within said upper chamber;at least one air circulator disposed within said upper chamber in operative association with said at least one evaporator for generating a flow of cooling air passing through said at least one evaporator;at least one generally vertically extending air return duct having an inlet opening superadjacent said floor and an outlet opening into said upper chamber; anda lower air return duct defining a bottom airflow passage lying superadjacent said floor and extending beneath the articles housed within said lower chamber, said lower air return duct having a generally horizontal, longitudinally extending base disposed in spaced relationship with and above said floor of said chamber and at least one side flange extending generally vertically downwardly therefrom to said floor of said chamber, said at least one side flange being perforated with a plurality of holes in flow communication with said at least one air return duct.
