Abstract

A modular refrigeration apparatus containing a cabinet with a front opening and divided into lower and upper portions, for separately receiving a plurality of removable modular units, said removable modular units including one of a selected plurality of interchangeable storage units and a universal refrigeration unit. A selected one of the plurality of interchangeable storage units is positioned within the upper portion of the cabinet for storing a plurality of containers. The refrigeration unit is positioned within the lower portion of the cabinet and in communication with the upper portion for cooling the entire interior of the cabinet. The cabinet is designed so that the interchangeable storage units and refrigeration unit can be respectfully removed or inserted from the cabinet without affecting the other units.

Claims

1. A refrigerated cabinet for selectively housing a coin-operating vending unit behind a substantially opaque door, or a self-serve product storage unit including product-storage shelves disposed behind a transparent door, said cabinet having an open front wall selectively coverable by one of the opaque or transparent doors and closed top, side and back walls, comprising:

a horizontal partition separating the cabinet into a refrigerated product storage compartment and an unrefrigerated compartment for housing a refrigeration unit, said horizontal partition defining an air intake opening in about the middle thereof and an air outlet opening near said back wall;

a vertical partition in said cabinet spaced from and disposed substantially parallel to the back wall defining an air plenum therebetween, said air plenum being in fluid communication with said outlet opening;

slot means formed in said vertical partition disposed in vertically extending columns, said columns being spaced horizontally across said vertical partition, said slot means directing air streams from said plenum through said storage compartment toward said front wall; and

fan means disposed in said bottom compartment for drawing air from the product storage compartment through said air intake opening, into operative engagement with said refrigeration unit and out said air outlet opening into said plenum;

whereby air flows in substantially circular paths up the back wall of the cabinet, toward the front wall and down the front wall into the unrefrigerated compartment.

2. The apparatus of claim 1 further including an additional horizontal partition in the product storage compartment extending from a rear edge thereof connected to the vertical partition near the bottom thereof to a front edge spaced from but closely adjacent to the front wall of the cabinet, said front edge being closer to the front wall than said intake opening in the other horizontal partition.

3. The apparatus of claim 2 further including vertically spaced air deflector baffles disposed in each vertical column of said slot means between each of a plurality of adjacent vertically spaced slots.

4. The apparatus of claim 1 further including vertically spaced air deflector baffles disposed in each vertical column of said slot means between each of a plurality of adjacent vertically spaced slots.
