FIELD OF THE INVENTION
[0001] 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.
BACKGROUND OF THE INVENTION
[0002] 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. In addition, refrigerator appliances also generally include
a door rotatably hinged to the cabinet to permit selective access to food items stored
in the chilled chamber. Often, refrigerator appliances include a machine compartment
in which a compressor or condenser is mounted.
[0003] It is common for typical refrigerators stick out from a wall or cabinet in which
they are installed. In order to address this concern, certain refrigerator appliances,
such as those commonly referred to as 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. Although aesthetically pleasing, this can cause further
issues. 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.
[0004] Some existing appliances have attempted to address these circulation concerns by
providing a transverse wall or panel that extends outward (i.e., toward a user) from
the machine compartment at a front face or lateral panel. Similarly, a wall that extends
from a door toward the machine compartment (e.g., when the door is closed) may be
provided. Unfortunately, having discontinuous elements or features extending in front
of the machine compartment often creates an unseemly appearance. Such a configuration
may also provide or create an intrusive surface that can catch fabric, dust, or even
a user's foot passing in front of the appliance.
[0005] As a result, further improvements for addressing air circulation of refrigerator
assemblies or appliances would be desirable. In particular, it would be useful to
provide a refrigerator assembly or appliance having one or more features for preventing
the mixing of airflows to/from a machine compartment while still providing a continuous
or uninterrupted front surface.
BRIEF DESCRIPTION OF THE INVENTION
[0006] Aspects and advantages of the invention will be set forth in part in the following
description, or may be obvious from the description, or may be learned through practice
of the invention.
[0007] In one exemplary aspect of the present disclosure, a refrigerator assembly is provided.
The 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

rearward from the louver panel at the air outlet.
[0008] In another exemplary aspect of the present disclosure, a refrigerator assembly is
provided. The 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.

DETAILED DESCRIPTION
[0011] Reference now will be made in detail to embodiments of the invention, one or more
examples of which are illustrated in the drawings. Each example is provided by way
of explanation of the invention, not limitation of the invention. In fact, it will
be apparent to those skilled in the art that various modifications and variations
can be made in the present invention without departing from the scope of the invention.
For instance, features illustrated or described as part of one embodiment can be used
with another embodiment to yield a still further embodiment. Thus, it is intended
that the present invention covers such modifications and variations as come within
the scope of the appended claims and their equivalents.
[0012] As used herein, the term "or" is generally intended to be inclusive (i.e., "A or
B" is intended to mean "A or B or both"). The terms "first,""second," and "third"
may be used interchangeably to distinguish one component from another and are not
intended to signify location or importance of the individual components. The terms
"upstream" and "downstream" refer to the relative flow direction with respect to fluid
flow in a fluid pathway. For example, "upstream" refers to the flow direction from
which the fluid flows, and "downstream" refers to the flow direction to which the
fluid flows. Terms such as "inner" and "outer" refer to relative directions with respect
to the interior and exterior of a refrigerator assembly. For example, "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.
[0013] Referring now to FIGS. 1 through 3, multiple perspective views are provided of an
exemplary refrigerator assembly
100. A refrigerator assembly
100 according to an embodiment of the present disclosure defines a vertical direction
V, a lateral direction L, and a transverse direction T (FIG. 3), each mutually perpendicular
to one another. As may be seen, the refrigerator appliance
100 includes a housing or cabinet
110 that extends between a top
112 and a bottom
114 along the vertical direction V, between a left (e.g., first lateral) side
116 and a right (e.g., second lateral) side
118 along the lateral direction L, and between a front end or side
120 (FIG. 3) and a rear end or side
122 (FIG. 3) along the transverse direction T.
[0014] The cabinet
110 generally defines one or more chilled chambers
128 (e.g., fresh food or freezer chambers) for receipt of food items for storage. Specifically,
the chilled chamber
128 is positioned between the left side
116 and the right side
118. In some embodiments, the chilled chamber
128 is positioned at or adjacent the top
112 of the cabinet
110. Nonetheless, it should be appreciated, that, except as otherwise indicate, the chilled
chamber
128 may be positioned at any suitable location within the refrigerator assembly
100. Moreover, although a single chilled chamber
128 is shown, it is understood that alternative embodiments may include any suitable
number or shape of chilled chambers
128 (e.g., to be maintained at separate or discrete temperatures).
[0015] The refrigerator assembly
100 may include one or more refrigerator doors
124 rotatably mounted to the cabinet
110, for example, such that the refrigerator door
124 permits selective access to at least a portion of the chilled chamber
128. In some embodiments, the refrigerator door
124is rotatably mounted to the cabinet
110 at one side (e.g., the right side
118) of the cabinet
110. A handle
130 may be positioned on the refrigerator door
124 to facilitate movement of the door
124 between a closed position (FIG. 1) that restricts access to the chilled chamber
128 (e.g., by extending across the chilled chamber
128) and an open position (FIG. 3) that permits access to the chilled chamber
128 (e.g., by being spaced apart from the chilled chamber
128).
[0016] As shown in FIG. 2, various storage components may be mounted within the food storage
chamber
100 to generally facilitate storage of food items. In certain embodiments, the storage
components include bins
132, drawers
134, and shelves
136 that are mounted within the chilled chamber
128. The bins
132, drawers
134, and shelves
136 are configured for receipt of food items (e.g., beverages or solid food items) and
may assist with organizing such food items.
[0017] Generally, 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).
For instance, one or more components of the sealed system (e.g., a compressor
238 or condenser
240) may be housed or within a machine compartment
210 defined by cabinet
110 (e.g., below or directly beneath chilled chamber
128). In some such embodiments, the machine compartment
210 is selectively covered or blocked by the door
124 (e.g., in the closed position). In particular, the machine compartment
210 may be positioned rearward from the door
124. Relative to the vertical direction V, one or more openings (e.g., lateral apertures
224) to the machine compartment
210 may be positioned above a bottom edge
126 of the door
124. Thus, when closed, the door
124 may hide one or more (e.g., all) lateral apertures
126 from the view of a user standing in front of the assembly
100.
[0018] Turning especially to FIGS. 3 through 6, various views are provided of the machine
compartment
210 (e.g., at the bottom
114 of cabinet
110). In certain embodiments, the machine compartment
210 spans the cabinet
110 along the lateral direction L from the left side
116 to the right side
118. In additional or alternative embodiments, the machine compartment
210 spans the cabinet
110 along the transverse direction T from the front end
120 to the rear end
122.
[0019] Generally, the machine compartment
210 includes an air inlet
212 (e.g., at the front end
120) to permit air to enter the machine compartment
210 and an air outlet
214 (e.g., at the front end
120) to permit air to exit the machine compartment
210. In certain embodiments, the air inlet
212 and the air outlet
214 are laterally adjacent to each other. For instance, the air inlet
212 and the air outlet
214 may be defined or located at discrete lateral positions. In some embodiments, the
air inlet
212 is located proximal to the right side
118 (i.e., distal to the left side
116) while the air outlet
214 is located proximal to the left side
116 (i.e., distal to the right side
118). Within the machine compartment
210, the machine compartment
210 includes one or more air channels (e.g., intake channel
216, 218 or output channel
220) to direct air through the machine compartment
210 from the air inlet
212 to the air outlet
214.
[0020] A louver panel
222 is mounted to the cabinet
110 in front of the machine compartment
210. In particular, 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). In some embodiments, the louver panel
222 extends along the lateral direction L from the left side
116 to the right side
118. Across at least a portion of the louver panel
222, 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. In certain embodiments, the lateral apertures
224 are uninterrupted or free of any discontinuous, interrupting element between the
first end
226 and the second end
228. Thus, the plurality of lateral apertures
224 may appear as continuous lines or openings (e.g., at the bottom of the refrigerator
assembly
100-FIG. 2). Moreover, the lateral apertures
224 may appear as the only openings below the chilled chamber
128. Each of the lateral apertures
224 may be spaced (e.g., vertically) apart from each other. In some such embodiments,
one or more of the lateral apertures
224 are parallel to each other. When mounted to the cabinet
110, the plurality of lateral apertures
224 extend across the air inlet
212 and the air outlet
214. The air inlet
212 and the air outlet
214 may be restricted or otherwise further defined by the louver panel
222.
[0021] 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).
[0022] Returning briefly to FIGS. 1 and 2, as noted above, the door
124 may be positioned in front of the machine compartment
210. When assembled, the door
124 may further be positioned in front of the louver panel
222. In some embodiments, the lower edge
126 of the door
124 is positioned below a bottom edge or bottommost lateral aperture
224 of the louver panel
222. Thus, in the closed position, the door
124 may cover or hide the louver panel
222. By contrast, in the open position of the door
124, access may be permitted to the louver panel
222 (e.g., such that the louver panel
222 and lateral apertures
224 are visible to a user in front of the refrigerator assembly
100).
[0023] Returning to FIGS. 3 through 6, in exemplary embodiments, 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. In some such embodiments, 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). In further embodiments, 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).
[0024] In certain embodiments, the compartment wall
230 extends from the front end
120 to a portion of the machine compartment
210 forward from the rear end
122 to define a transverse intake portion
216. Moreover, a transverse gap between the compartment wall
230 and rear end
122 of the cabinet
110 may define a lateral intake portion
218 (e.g., as a continuation or part of intake channel). In some such embodiments, the
output channel
220 is defined along the lateral direction L between the left side
116 and the compartment wall
230, while being defined along the transverse direction T between the front end
120 and the air handler
242. At least a portion of the intake channel (e.g., transverse intake portion
216) 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. Relative to fluid flow, 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.
[0025] As noted above, one or more portions of the sealed refrigeration system may be housed
within the machine compartment
210. In some embodiments, a compressor
238 configured to compress or motivate a refrigerant through the sealed system is mounted
to the cabinet
110 within the machine compartment
210 (e.g., in the output channel
220). In additional or alternative embodiments, a condenser
240 (e.g., in fluid communication with the compressor
238) is housed within the machine compartment
210. For instance, the condenser
240 may be positioned adjacent to the rear end
122 of cabinet
110 (e.g., within intake channel at transverse intake portion
216 or lateral intake portion
218, as shown). In some such embodiments, the condenser
240 is positioned rearward from the compressor
238.
[0026] In some embodiments, 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). For instance, 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. In certain embodiments,
the air handler
242 is positioned upstream from the compressor
238. In additional or alternative embodiments, the air handler
242 is positioned downstream from the condenser
240. Optionally, the air handler
242 may be positioned between the compressor
238 and the condenser
240 along the transverse direction T. In further additional or alternative embodiments,
the air handler
242 is positioned between the output channel
220 and the intake channel
216, 218 (e.g., between the condenser
240 and the compressor
238). The output channel
220 may thus be a positive pressure channel while the intake channel
216, 218 is a negative pressure channel. In optional embodiments, one or more secondary apertures
244 are defined through the rear end
122 of the cabinet
110 in fluid communication with the air handler
242 to provide supplemental or secondary air to mix with air from the intake channel
216, 218 (e.g., within the lateral intake portion
218 or output channel
220).
[0027] As shown, a plurality of laterally-spaced vanes
246, 248 are provided adjacent to the louver panel
222. In some embodiments, the vanes
246,
248 are fixed or mounted to the louver panel
222. For instance, one or more adhesives, welds, or mechanical fasteners may secure the
vanes246, 248 directly to the louver panel
222. Selective removal or mounting of the louver panel
222 from the cabinet
110, may thus advantageously provide removal or mounting of the vanes
246, 248 within the mechanical compartment.
[0028] Generally, the vanes
246, 248 extend rearward from the louver panel
222 (e.g., at the air outlet
214). Thus, when assembled, the vanes
246,
248 are positioned opposite a front-facing surface of the louver panel
222 and are advantageously hidden from a user's view or contact. Each of the vanes
246, 248 is laterally spaced apart from the others along the lateral direction L. Separate
air paths may thus be defined between adjacent vanes
246, 248. When assembled, the vanes
246, 248 may be positioned within at least a portion of the output channel
220 (e.g., proximal to the front end
120). In optional embodiments, the vanes
246, 248 may be positioned in front of the compressor
238 or air handler
242(e.g., along or relative to the transverse direction T).
[0029] In certain embodiments, one or more vanes (e.g., of a first vane set
246) are directed away from the right side
118 or the air inlet
212. For instance, one or more vanes
246A
, 246B may be non-parallel to the transverse direction T. At least one vane
246, 248 may define a flow angle θ
1(e.g., relative to the transverse direction T) directed away from, for instance, the
second end
228. Optionally, multiple vanes
246 may define flow angles θ
1 directed away from the second end
228. In some such embodiments, separate vanes
246 define separate flow angles θ
1. For instance, the flow angles θ
1 may generally and sequentially increase relative to the transverse direction T as
the lateral distance between discrete vanes
246increases relative to the second end
228 or air inlet
212. Thus, the flow angle θ
1 defined by a first vane
246A proximal to the second end
228 may be less than the flow angle θ
1 defined by a second vane
246B distal from the second end
228 (i.e., distal in comparison to the first vane
246A)
. Advantageously, air from the air outlet
214 may be substantially prevented from mixing with air entering machine compartment
210 (e.g., through air inlet
212).
[0030] In additional or alternative embodiments, one or more vanes (e.g., of a second vane
set
248) are directed away from the left side
116. For instance, one or more vanes
248 may be non-parallel to the transverse direction T. At least one vane
248 may define a flow angle θ
2 (e.g., relative to the transverse direction T) directed away from, for instance,
the first end
226. Optionally, multiple vanes
248 may define flow angles θ
2 directed away from the first end
226. In some such embodiments, separate vanes
248 define separate flow angles θ
2. For instance, the flow angles θ
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. Thus, the flow angle θ
2 defined by a first vane
248A proximal to the first end
226 may be less than the flow angle θ
2 defined by a second vane
248B distal from the first end
226 (i.e., distal in comparison to the first vane
248A).
[0031] In optional embodiments, 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. In some such embodiments, the first set of vanes
246 is further directed toward the second set of vanes
248, and vice versa. Thus, 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. Moreover, 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.
[0032] Turning now briefly to FIG. 7, a further exemplary embodiment of refrigerator assembly
100 is provided. As shown, refrigerator assembly
100 includes a discrete primary cabinet
110 and secondary cabinet
310. Generally, it is understood that the primary cabinet
110 may include a machine compartment
210, including one or more of the above-described features. Secondary cabinet
310 may include one or more similar features. For instance, the secondary cabinet
310 may extend along the lateral direction L between a left side (e.g., first lateral)
side
316 and a right side (e.g., second lateral) side
318 to define a chilled chamber
324 and a machine compartment
410 (e.g., below the chilled chamber
324). The machine compartment
410 of the secondary cabinet
310 may include a separate air inlet
412 and air outlet
414. As described above within the context of machine compartment
210, the air inlet
412 may be positioned proximal to the right side
318 while the air outlet
414 may be positioned proximal to the left side
320. In optional embodiments, the door
324 of the secondary cabinet
310 may be rotatably attached at an opposite side from the door
124 of the primary cabinet
110 (e.g., the left side
316).
[0033] As shown, the right side
318 of the secondary cabinet
310 may be positioned against the left side
116 of the primary cabinet
110. The air inlet
412 of the machine compartment
410 of the secondary cabinet
310 may be located proximal to the air outlet
214 of the machine compartment
210 of the primary cabinet
110. In some such embodiments, a plurality of vanes (e.g., second set
148-FIG. 3) within machine compartment
210 is directed toward the right side
118. Advantageously, air output from the machine compartment
210 may thus be directed away from the air inlet
412of the machine compartment
410.
