First Claim
1. A refrigeration unit for holding storage items to be refrigerated, said refrigeration unit comprising:
- an insulated enclosure defining a compartment, said enclosure having a top wall, a rear wall and opposing side walls;
an evaporator disposed within the compartment and secured to the rear wall;
a drain trough secured to the rear wall below the evaporator;
an evaporator plate covering the evaporator and having a lower portion sloping rearwardly and downwardly toward the drain trough, said lower portion directing condensate from the evaporator into the drain trough; and
a drain plate covering the lower portion of the evaporator plate and the drain trough so as to prevent storage items from coming into contact with condensate dripping into the drain trough from the lower portion of the evaporator plate, said drain plate, in conjunction with the evaporator plate, forming a rear channel with the rear wall.

Abstract
A refrigeration unit for storing items to be refrigerated. The refrigeration unit includes an insulated enclosure defining a compartment, and has a top wall, a rear wall, and opposing side walls. An evaporator is disposed within the compartment and is secured to the rear wall. An evaporator cover has a top portion and a rear portion. The rear portion covers the evaporator and has a sloping rear face that slopes rearwardly and downwardly toward a drain trough. The sloping rear face directs condensate from the evaporator into the drain trough. A drain plate covers the drain trough and the sloping rear face. An angled grate is secured to the drain plate and covers an inlet to an air flow channel formed by the rear wall, and the evaporator cover and the drain plate. A fan is secured over an angled opening formed in the top portion of the evaporator cover and is operable to draw air through the air flow channel.

12. A refrigeration unit for holding storage items to be refrigerated, said refrigeration unit comprising;
-
an insulated enclosure defining a compartment, said enclosure having a top wall, a rear wall and opposing side walls; a rear plate spaced forward from the rear wall so as to form a rear channel therewith, said rear plate having a lower end spaced forward from the rear wall so as to form an inlet for the rear channel; an evaporator disposed within the rear channel; a drain trough disposed within the rear channel below the evaporator; and a grate covering the inlet to the rear channel so as to prevent storage items from being pressed up against the lower end of the rear plate and blocking air flow into the inlet of the rear channel wherein the grate slopes downwardly and rearwardly to the rear wall so as to help prevent storage items from being disposed flush against the grate and blocking air flow through the grate. - View Dependent Claims (13, 14, 15, 16)

17. A refrigeration unit for holding storage items to be refrigerated, said refrigeration unit comprising:
-
an insulated enclosure defining a compartment, said enclosure having a top wall, a rear wall and opposing side walls; an evaporator disposed within the compartment and secured to the rear wall; a drain trough secured to the rear wall below the evaporator; an evaporator plate covering the evaporator and forming an evaporator channel with the rear wall, said evaporator plate having a lower portion sloping rearwardly and downwardly toward the drain trough, said lower portion directing condensate from the evaporator into the drain trough; a top plate having an angled portion defining an opening, said top plate being spaced downward from the top wall so as to form a top channel therewith, said top channel adjoining the evaporator channel; and a fan disposed within the top channel and secured over the opening so as to be angled, said fan being operable to draw air through the evaporator channel and the top channel, and to expel the air into the compartment through the opening at an angle. - View Dependent Claims (18, 19, 20, 21)
