Definitions

the present subject matter relates generally to refrigerator assemblies or appliances, and more particularly to features thereof for improving air circulation through a machine compartment of a refrigerator assembly.
Refrigerator assemblies or appliances generally include a cabinet that defines a chilled chamber, such as a fresh food chamber or a freezer chamber, for storing food or other perishable items.
refrigerator appliances also generally include a door rotatably hinged to the cabinet to permit selective access to food items stored in the chilled chamber.
refrigerator appliances include a machine compartment in which a compressor or condenser is mounted.
refrigerator appliances such as those commonly referred to as built-in refrigerators
built-in refrigerators are configured to be installed in a cabinet such that a refrigerator appliance appears to be an integral part of the kitchen or room.
a machine compartment must often be vertically stacked, for instance, below the chilled chamber. Therefore, it can be difficult to circulate air through the machine compartment for heat exchange.
An air inlet and an air outlet must often be located adjacent to each other, for instance, at a front face of the refrigerator. In turn, it is often especially difficult to prevent an intake airflow into the machine compartment from mixing with an output airflow from the machine compartment.
a refrigerator assembly may include a cabinet, a louver panel, and a plurality of laterally-spaced vanes.
the cabinet may extend along a lateral direction between a first lateral side and a second lateral side.
the cabinet may define a chilled chamber and a machine compartment.
the machine compartment may have an air inlet and an air outlet separate from the air inlet.
the louver panel may be mounted to the cabinet in front of the machine compartment.
the louver panel may define a plurality of lateral apertures spaced apart along a vertical direction.
the plurality of lateral apertures may extend along the lateral direction in front of the air inlet and the air outlet from a first end to a second end.
the plurality of laterally-spaced vanes may extend rearward from the louver panel at the air outlet.
a refrigerator assembly may include a cabinet, a louver panel, and a plurality of laterally-spaced vanes.
the cabinet may extend along a lateral direction between a first lateral side and a second lateral side.
the cabinet may define a chilled chamber and a machine compartment.
the machine compartment may have an air inlet and an air outlet separate from the air inlet.
the louver panel may be mounted to the cabinet in front of the machine compartment.
the louver panel may define a plurality of lateral apertures spaced apart along a vertical direction.
the plurality of lateral apertures may extend along the lateral direction in front of the air inlet and the air outlet from a first end to a second end.
the plurality of laterally-spaced vanes may extend rearward from the louver panel at the air outlet.
the plurality of laterally-spaced vanes may be directed away from the panel inlet.
inner or “inward” refers to the direction towards the interior of the refrigerator appliance.
Terms such as “left,””right,””front,””forward,””back,””rearward,””top,” or “bottom” are used with reference to the perspective of a user accessing the refrigerator appliance. For example, a user stands in front of the refrigerator to open the doors and reaches into the chilled chamber(s) to access items therein.
a sealed system is provided to cool air within chilled chamber 128 (e.g., at least in part by circulating a refrigerant as part of a refrigeration cycle).
one or more components of the sealed system e.g., a compressor 238 or condenser 240
the machine compartment 210 is selectively covered or blocked by the door 124 (e.g., in the closed position).
the machine compartment 210 may be positioned rearward from the door 124.
a louver panel 222 is mounted to the cabinet 110 in front of the machine compartment 210.
the louver panel 222 may be positioned in front of an opening that defines, at least in part, the air inlet 212 and the air outlet 214 (e.g., below the chilled chamber 128 - FIG. 2 ).
the louver panel 222 extends along the lateral direction L from the left side 116 to the right side 118.
a plurality of lateral apertures 224 are defined. As shown, the plurality of lateral apertures 224 extend along the lateral direction L from a first end 226 to a second end 228.
the lateral apertures 224 generally extend along the transverse direction T from the machine compartment 210 to the front 120 of the assembly 100. In optional embodiments, one or more of the lateral apertures 224 extends at an angle (e.g., non-parallel) to the transverse directionT. For instance, one or more lateral apertures 224 may be directed downward from the machine compartment 210 at a negative angle relative to the transverse direction T. Air directed from the machine compartment 210 through the lateral apertures 224 may thus flow forward from the machine compartment 210 and toward the ground (e.g., away from the chilled chamber 128).
a compartment wall 230 is provided within machine compartment 210. As shown, the compartment wall 230 generally extends along the transverse direction T (e.g., rearward relative to the louver panel 222). The compartment wall 230 may be positioned between the air inlet 212 and the air outlet 214 (e.g., relative to the lateral direction L). The compartment wall 230 may help block or define a separate air intake channel (e.g., having a transverse intake portion 216 or a lateral intake portion 218) and air output channel 220. During use, the air output channel 220 is downstream from the air intake channel 216 or 218 within the machine compartment 210 .
the compartment wall 230 extends from an upper end 232 to a lower end 234 of the machine compartment 210. Air entering the machine compartment 210 through the air inlet 212 may thus be prevented from immediately intermingling with air to be ejected from the air outlet 214 (e.g., at the front end 120 of the cabinet 110).
the compartment wall 230 is mounted or fixed to a base pan or floor 236 of the cabinet 110 (e.g., defining a lowermost portion of the machine compartment 210).
At least a portion of the intake channel may be defined along the lateral direction L between the right side 118 and the compartment wall 230, while being defined along the transverse direction T between the front end 120 and the lateral intake portion 218.
the lateral intake portion 218 may be located between the transverse intake portion 216 and the output channel 220. During use, air may thus flow, for example, from the transverse intake portion 216 to the lateral intake portion 218 before passing to the output channel 220.
an air handler 242 such as a fan or blower, is housed within the machine compartment 210 to motivate or urge an airflow therethrough (e.g., from the air inlet 212 to the air outlet 214).
the air handler 242 may be directed at the compressor 238 or condenser 240 to draw air across portions of the sealed system and facilitate or encourage heat exchange between the sealed system and the ambient environment.
the air handler 242 is positioned upstream from the compressor 238.
the air handler 242 is positioned downstream from the condenser 240.
the air handler 242 may be positioned between the compressor 238 and the condenser 240 along the transverse direction T.
one or more vanes are directed away from the left side 116.
one or more vanes 248 may be non-parallel to the transverse direction T.
At least one vane 248 may define a flow angle ⁇ 2 (e.g., relative to the transverse direction T) directed away from, for instance, the first end 226.
multiple vanes 248 may define flow angles ⁇ 2 directed away from the first end 226.
separate vanes 248 define separate flow angles ⁇ 2 .
the flow angles ⁇ 2 may generally and sequentially increase relative to the transverse direction T as the lateral distance between discrete vanes 248 increases relative to the first end 226.
both a first set of vanes 246 (e.g., directed toward the left side 116) and a second set of vanes 248 (e.g., directed toward the right side 118) are provided.
the first set of vanes 246 is further directed toward the second set of vanes 248, and vice versa.
air directed from the first set of vanes 246 may be guided to merge with air from the second set of vanes 248 in front of the cabinet 110.
the first set of vanes 246 may be positioned proximal to the right side 118 while the second set of vanes 248 is positioned proximal to the left side 116.
