Wall covering assembly with ventilation pattern and air curtain system
A refrigerator includes a wall covering assembly having a top wall spaced-apart from a top wall of a liner, and a rear wall spaced-apart from a rear wall of the liner. The wall covering assembly includes a pattern of ports for providing outwardly directed cooled air to the refrigerator cabinet from a duct assembly. The duct assembly is configured to deliver cooled air through the ventilated portion of the wall covering assembly and also deliver cooled air to a front portion of the refrigerator cabinet via a downwardly directed air curtain. The air curtain disrupts the outward flow of air from the ventilated portion of the wall covering assembly before the cooled air reaches a gasket assembly disposed around the refrigerator doors. Angled venting slots disposed on the wall covering assembly direct air towards inner surfaces of the doors without disruption from the air curtain.

a fan housing having a fan disposed therein;
an evaporator operably coupled to the fan housing, wherein the fan housing and the evaporator are disposed within the first portion of the cavity below the ventilated portion of the wall covering assembly.
3. The refrigerator of claim 1 , wherein the ventilated portion of the rear wall of the wall covering assembly is disposed between opposite ends of the rear wall of the wall covering assembly.
4. The refrigerator of claim 3 , wherein the opposite ends of the rear wall of the wall covering assembly abut the first and second sidewalls of the liner, respectively.
5. The refrigerator of claim 4 , wherein the plurality of ports includes a pattern of ports that substantially covers an entirety of the ventilated portion between the opposite ends of the rear wall of the wall covering assembly.
6. The refrigerator of claim 1 , wherein the rear wall of the wall covering assembly includes an inclined portion extending inwardly into the refrigerator cabinet, and further wherein the inclined portion of the wall covering assembly defines a housing area disposed below the first portion of the cavity.
7. The refrigerator of claim 1 , wherein the first portion of the cavity opens into the second portion of the cavity.
8. A refrigerator, comprising:
a liner including a top wall, first and second sidewalls, a bottom wall and a rear wall;
a wall covering assembly having a top wall disposed below the top wall of the liner and a rear wall disposed in front of the rear wall of the liner, wherein the rear wall of the wall covering assembly includes a ventilated portion having a plurality of ports disposed therethrough, wherein the liner and the wall covering assembly cooperate to define a refrigerator cabinet; and
a cavity formed between liner and the wall covering assembly, the cavity including a first portion disposed between the rear wall of the liner and the rear wall of the wall covering assembly, and a second portion disposed between the top wall of the liner and the top wall of the wall covering assembly; and
an air distribution system concealed by the wall covering assembly, wherein the air distribution system includes a duct assembly having first and second upright ducts spaced apart from one another that direct air flow into a rear portion of the refrigerator cabinet through the plurality of ports along the ventilated portion of the wall covering assembly, wherein the duct assembly further includes first and second upper ducts extending outwardly in a substantially perpendicular manner relative to the first and second upright ducts from a rear portion of the refrigerator cabinet to a front portion of the refrigerator cabinet, and further wherein the first and second upper ducts each include a downwardly opening vent.
9. The refrigerator of claim 8 , wherein the ventilated portion of the wall covering assembly is disposed between opposite sides of the rear wall of the wall covering assembly.
10. The refrigerator of claim 9 , wherein the opposite sides of the rear wall of the wall covering assembly are operably coupled to the first and second sidewalls of the liner, respectively.
