Referring to FIGS. 1-8, reference numeral 10 generally designates an appliance that includes a cabinet 12. The cabinet 12 includes a wrapper 14 and a liner 16 coupled to the wrapper 14. A vacuum insulated cavity 18 is defined between the wrapper 14 and the liner 16. A wire on tube condenser 20 is coupled to a rear portion 22 of the cabinet 12. The wire on tube condenser 20 extends from a top region 24 of a machine compartment 26 and towards a top portion 28 of the cabinet 12. A plurality of engagement plates 30 is coupled to opposing side sections 32, 34 of the wire on tube condenser 20 and is disposed along a length of the wire on tube condenser 20. A plurality of hangers 36 is coupled to the rear portion 22 of the cabinet 12 and protrudes outward from the rear portion 22. The plurality of hangers 36 each includes a stem 38 and a head 40 at the end of the stem 38. The plurality of hangers 36 is disposed in a plurality of slotted features 42 defined on the plurality of engagement plates 30 to couple the wire on tube condenser 20 to the cabinet 12.

Referring to FIGS. 1 and 2, the appliance 10 is illustrated as a refrigerator appliance with a door assembly 60 operably providing access to a refrigerator compartment 62 and a lower pull-out drawer 64 providing access to a freezer compartment 66, however, it is contemplated that the cabinet 12 with the wrapper 14, liner 16, and vacuum insulated cavity 18 may be used with a variety of appliances, structures, or refrigeration purposes other than with an appliance. Moreover, the illustrated appliance 10 is a bottom-mount refrigerator. In non-limiting examples, the appliance 10 can be a bottom-mount refrigerator, a bottom-mount French door refrigerator, and/or a five-door French door refrigerator, each of which can have the wire on tube condenser 20.

In the depicted example of FIG. 1, the cabinet 12 includes the wrapper 14 that is coupled to the liner 16 and a trim breaker 70 to define the vacuum insulated cavity 18. The wrapper 14 includes a front edge 80 defining an opening 82, a rear panel 84 opposing the front edge 80, a top panel 86 and an opposing bottom panel 88 between the front edge 80 and the rear panel 84, and a first side panel 90 and an opposing second side panel 92 between the front edge 80 and the rear panel 84. The wrapper 14 may be made from a material at least partially resistant to bending, deformation, or otherwise being formed in response to an inward compressive force 94. These materials for the wrapper 14, include, but are not limited to, metals, polymers, metal alloys, combinations thereof, and/or other similar substantially rigid materials that can be used for vacuum insulated structures.

Referring further to FIGS. 1 and 2, the liner 16 is at least partially enclosed by the wrapper 14. The liner 16 includes a front edge 100, a rear section 102 that opposes the front edge 100, a top section 104 and an opposing bottom section 106 between the front edge 100 and the rear section 102, and side sections 108, 110 between the top section 104 and the bottom section 106. Further, as illustrated in FIG. 3, the liner 16 has intermediate sections extending between the refrigerator 62 and freezer compartments 66. One intermediate section may form a lower portion of the refrigerator compartment 62, while a second intermediate section may form an upper portion of the freezer compartment 66. The intermediate sections extend from the front edge 100 to the rear section 102 and are configured to separate the compartments 62, 66 and defined a mullion region therebetween. In such configurations, the liner 16 may be multiple components.

As illustrated in FIGS. 1 and 2, each section 102, 104, 106, 108, 110 of the liner 16 is proximate a respective panel 84, 86, 88, 90, 92 of the wrapper 14. Similarly, each section 102, 104, 106, 108, 110 of the liner 16 may have a shape and size that coincides with the shape and size of the respective panel 84, 86, 88, 90, 92 of the wrapper 14. The liner 16 may be made from a material at least partially resistant to bending, deformation, or otherwise being formed in response to the inward compressive force 94. These materials for the liner 16 include, but are not limited to, metals, polymers, metal alloys, combinations thereof, and/or other similar substantially rigid materials that can be used for vacuum insulated structures.

The trim breaker 70 couples the wrapper 14 to the liner 16 to define and seal the vacuum insulated cavity 18. The trim breaker 70 is generally disposed proximate to the opening 82 of the wrapper 14. The trim breaker 70 includes one or more channels that receive the front edge 80 of the wrapper 14 and the front edge 100 of the liner 16. An adhesive is then disposed within one or more of the channels to couple the front edge 80 of the wrapper 14 and the front edge 100 of the liner 16 to the trim breaker 70 such that a sealed interface is defined. The wrapper 14, the liner 16, and the trim breaker 70 are sealed and airtight such that air can neither escape nor enter into the vacuum insulated cavity 18 between the wrapper 14 and the liner 16.

The appliance 10 illustrated in FIGS. 1 and 2 defines the vacuum insulated cavity 18, in which one or more insulation materials may be disposed. The insulation materials may be a carbon-based powder and/or silicone oxide-based materials, however, it is generally contemplated that other insulation materials may be used. Additionally, the insulation materials can be free-flowing materials that can be poured, blown, compacted, or otherwise disposed within the vacuum insulated cavity 18. This free-flowing material can be in the form of various silica-based materials, such as fumed silica, precipitated silica, nano-sized, and/or micro-sized aerogel, powder, rice husk ash, powder, perlite, glass spheres, hollow glass spheres, cenospheres, diatomaceous earth, combinations thereof, and/or other similar insulating particulate materials.

In various examples, the one or more insulation materials may substantially fill the vacuum insulated cavity 18 to form a substantially continuous layer between the wrapper 14 and the liner 16. A vacuum, or at least a partial vacuum, may be defined within the vacuum insulated cavity 18 and may define a pressure differential between an exterior of the appliance 10 and the vacuum insulated cavity 18. This pressure differential may serve to define the inward compressive force 94 that may be exerted upon one and/or both of the wrapper 14 and the liner 16. Further, the door assembly 60 and the lower pull-out drawer 64 may also be vacuum insulated structures. In such examples, the door assembly 60 and/or the lower pull-out drawer 64 may have a structural wrapper defining a vacuum insulated cavity with insulating materials and defining an at least partial vacuum.

Referring still to FIG. 2, as well as FIG. 3-5, the appliance 10 includes the wire on tube condenser 20 coupled to the rear portion 22 of the cabinet 12. The wire on tube condenser 20 includes a wire grid 120 and a tube 122 coupled to the wire grid 120. The wire grid 120 includes multiple wires 124 that are coupled to the tube 122 and are uniformly spaced relative to one another. The wires 124 extend along a width and/or a length of the cabinet 12. For example, in the illustrated example of FIG. 2, the wire grid 120 is shown with wires 124 extending along a length of the cabinet 12. The wire grid 120 may be made of various materials, such as a metal, a plastic, a combination, or a combination thereof.

Referring still to FIGS. 2-5, the tube 122 of the wire on tube condenser 20 is coupled to the wire grid 120. In some examples, the tube 122 can extend along the width and/or the length of the rear panel 84. For example, the tube 122 can define a sinuous, “S”-shaped, or serpentine configuration that extends across the wires 124 from the top region 24 of the machine compartment 26 and towards the top portion 28 of the appliance 10.

In the illustrated example of FIG. 2, the tube 122 is shown in the sinuous pattern, where straight segments 126 of the tube 122 extend along a width of the rear panel 84, and bends 128 of the tube 122 generally extend along a length of the rear panel 84. According to various aspects, refrigerant passes through the tube 122, where thermal energy within the refrigerant is transferred to the tube 122, and subsequently to ambient air external the tube 122. To permit transfer of thermal energy, the tube 122 may be made of various conductive materials such as copper, aluminum, a conductive metal, a conductive composite, and/or various other conductive materials. According to various aspects, the wire on tube condenser 20, by having a sinuous “S”-shaped configuration extending along the rear panel 84 and by being made from a conductive material, provides for a heat exchanger with a greater surface area that can effectively reduce refrigerant temperature through natural convection with ambient air surrounding the wire on tube condenser 20.

Referring still to FIG. 2, the wire on tube condenser 20 is illustrated as coupled to the rear portion 22 of the cabinet 12. In the illustrated example of FIG. 2, the wire on tube condenser 20 is shown coupled to the rear panel 84 of the wrapper 14, extending from the top region 24 of the machine compartment 26 to the top portion 28 of the appliance 10. In various examples, the wire on tube condenser 20 is coupled to a first side portion 130 and/or a second side portion 132 of the rear panel 84 of the wrapper 14. The side portions 130, 132 may each generally form about half of the rear panel 84.

In such examples, the portion 130 where the wire on tube condenser 20 is coupled may have a thickness that varies from the thickness of the other portion 132. For example, the wire on tube condenser 20 can be coupled to the first side portion 130, and the first side portion 130 may have a thickness less than a thickness of the second side portion 132 such that the first side portion 130 is recessed relative to the second side portion 132. Further, in such examples, the wire on tube condenser 20, once coupled to the first side portion 130, may be recessed from, flush to, or protruding relative to the second side portion 132. In protruding examples, the wire on tube condenser 20 may protrude relative to the second side portion 132 due to the lesser thickness of the first side portion 130. Additionally, or alternatively, in aspects where the wire on tube condenser 20 is coupled to the first side portion 130, it is also contemplated that the first side portion 130 may have a thickness greater than the second side portion 132 to increase insulation of the rear panel 84 proximate the wire on tube condenser 20.

Referring again to FIGS. 2-5, the plurality of engagement plates 30 are coupled to the wire on tube condenser 20. According to various aspects, the wire on tube condenser 20 and the plurality of engagement plates 30 may be collectively referred to as a condenser assembly. The plurality of engagement plates 30 is generally disposed along a length or height of the wire on tube condenser 20. The plurality of engagement plates 30 can be coupled to the opposing side sections 32, 34 of the wire on tube condenser 20. For example, the plurality of engagement plates 30 may include a first set 144 and a second set 146 of engagement plates 160 that are coupled to the first side section 32 and the second side section 34 of the wire on tube condenser 20. In such examples, the second set 146 of engagement plates 160 may mirror the first set 144 of engagement plates 160. In some examples, one or more engagement plates 160 may be coupled to the opposing side sections 32, 34 and at least partially extend beyond each side section 32, 34. In this way, the engagement plates 160 extend or project beyond the wires 124 and the tube 122 of the wire on tube condenser 20.

Additionally, it is generally contemplated that the engagement plates 160 may include any practicable number of engagement plates 160 for supporting the wire on tube condenser 20. For example, the engagement plates 160 may include four engagement plates 160, twelve engagement plates 160, or other various amounts of engagement plates 160. In the illustrated configuration, there are twelve engagement plates 160 coupled to the wire on tube condenser 20, with six engagement plates 160 on each side section 32, 34 of the wire on tube condenser 20.

It is also generally contemplated that the first set 144 of engagement plates 160 and the second set 146 of engagement plates 160 may be of a same or different configuration from the other set 144, 146 of engagement plates 160. The first set 144 of engagement plates 160 may be disposed in a same or differing pattern to the second set 146 of engagement plates 160. As illustrated, the first set 144 of engagement plates 160 and the second set 146 of engagement plates 160 are horizontally aligned with one another, forming mirrored configurations. However, the engagement plates 160 of the first set 144 may be offset, include a different number, or otherwise differ from the second set 146 of engagement plates 160.

Referring still to FIGS. 4 and 5, each engagement plate 160 includes a base segment 162 and an end segment 164 extending from the base segment 162. The base segment 162 is coupled to the wire on tube condenser 20. In some examples, the base segment 162 may be coupled to the wire grid 120 and/or the tube 122. For example, the base segment 162 may be welded to the wire grid 120. The base segment 162 may be of various sizes and define various shapes, such as a quadrilateral shape.

The end segment 164 may be integrally formed or coupled with the base segment 162 such that the end segment 164 extends from the base segment 162. The end segment 164 may be of a shape and size that differs from or coincides with a shape and size of the base segment 162. For example, the end segment 164 may have a height greater than a height of the base segment 162 such that a top edge 166 of the end segment 164 is offset from or above the base segment 162. According to various aspects, each engagement plate 160 may be positioned on the wire on tube condenser 20 such that each end segment 164 extends beyond outer edges 168, 170 of each opposing side section 32, 34. Accordingly, the end segments 164 may be utilized to couple the wire on tube condenser 20 with the cabinet 12 without interfering with the wires 124 or the tube 122.

Referring again to FIGS. 2-5, each engagement plate 160 defines a slotted feature 182. The slotted features 182 together define the plurality of slotted features 42. Each slotted feature 182 is generally defined on the end segment 164 of a respective engagement plate 160. Accordingly, each engagement plate 160 defines one slotted feature 182 outwardly from the respective outer edge 168, 170 of the wire on tube condenser 20.

Each slotted feature 182 includes a receiving portion 184 and a slot portion 186. Generally, the slot portion 186 is an extension of the receiving portion 184 to form two portions of a single aperture. As illustrated in FIGS. 4 and 5, the receiving portion 184 is defined on the end segment 164 and defines a generally circular or oblong shape. The receiving portion 184 has a shape and width that generally corresponds with the shape and width of each hanger 188. For example, the receiving portion 184 can have a circular shape that corresponds to a circular shape of each hanger 188, and the receiving portion 184 can have a width that permits insertion of the hanger 188 into or through the receiving portion 184.

As illustrated in FIGS. 4 and 5, for each engagement plate 160, the slot portion 186 extends from the receiving portion 184 of the slotted feature 182. According to various aspects, the slot portion 186 can extend from the receiving portion 184 in various directions. For example, as illustrated, the slot portion 186 extends toward the top edge 166 of the end segment 164. The slot portion 186 can be defined as having various shapes, such as a circular, rectangular, or oval shape.

The slot portion 186 may have a width that is less than the width of the receiving portion 184. In some examples, the width of the slot portion 186 may coincide with the width of the hanger 188. For example, the slot portion 186 may have a width such that the hanger 188 may be inserted into the receiving portion 184 and then translated along the slot portion 186, as provided herein. In such examples, the length of the slot portion 186 may at least partially determine the length of translation provided until the hanger 188 abuts an inner surface 200 of the slot portion 186.

According to various aspects, the slotted features 182 are configured to permit insertion of the hangers 188 into respective slotted features 182. The slotted features 182 are further configured to permit translation of the wire on tube condenser 20 such that each hanger 188 translates into respective slot portions 186 and engages with the respective engagement plate 160. Once the hangers 188 are inserted into the slot portions 186 and abutting the inner surfaces 200, respectively, the wire on tube condenser 20 may be statically coupled to the cabinet 12 via engagement between the engagement plates 30 and the hangers 36. Accordingly, the wire on tube condenser 20 may be retained in a hanging arrangement on the cabinet 12. Additionally, it is generally contemplated that additional components, structures, and/or material properties may be provided that assist in coupling the engagement plates 30 to the hangers 188.

Referring to FIGS. 2, 3, and 6, the hangers 188 are coupled to the rear panel 84 of the wrapper 14 and extend outward from the rear panel 84. The hangers 188 may be disposed along a width or a length of the rear panel 84 and/or the wire on tube condenser 20. In various aspects, the hangers 188 can be disposed on the rear panel 84 to be positioned proximate to the outer edges 168, 170 of the opposing side sections 32, 34 of the wire on tube condenser 20 when the wire on tube condenser 20 is coupled to the rear panel 84.

In additional or alternative aspects, the hangers 188 may be spaced apart such that the hangers 188 align with the engagement plates 160. For example, a first set 210 of hangers 188 may align with the first set 144 of engagement plates 160, and a second set 212 of hangers 188 may align with the second set 146 of engagement plates 160.

Additionally, or alternatively, it is generally contemplated that the plurality of hangers 36 may include any practicable number of hangers 188. For example, the plurality of hangers 36 may include four hangers 188, twelve hangers 188, or other various amounts of hangers 188. It is also generally contemplated that the first set 210 of hangers 188 and the second set 212 of hangers 188 may be of a same or different configuration of the other set 210, 212 of hangers 188. The first set 210 of hangers 188 may be disposed in a same or different pattern to the second set 212 of hangers 188. In general, the appliance 10 includes the same number of hangers 188 as engagement plates 160, and the hangers 188 and engagement plates 160 are disposed in the same pattern or configuration. However, the appliance 10 may also include different numbers or arrangements of hangers 188 and engagement plates 160 without departing from the teachings herein.

Each hanger 188 includes the stem 38 that is coupled to the rear panel 84 and extends outward from the rear panel 84, and the head 40 extending from the stem 38. According to various aspects, the stem 38 may be configured as a stud that is welded to the rear panel 84 and extends from the rear panel 84. The stem 38, by being directly welded to the rear panel 84 and extending from the rear panel 84, permits the coupling of the hangers 188 to the rear panel 84 while still maintaining a vacuum in the vacuum insulated cavity 18.

In various aspects, each hanger 188 may include the hanger base 220 coupled to the rear panel 84, and the stem 38 may be coupled to or integrally formed with the hanger base 220. For example, each stem 38 may be integrally formed with and extend from a respective hanger base 220 that is coupled to the rear panel 84. Accordingly, the stem 38 and the respective base 220 may be formed as a single, unitary component. Similar to the stem 38 being directly coupled to the rear panel 84, in examples with the hanger bases 220, the hanger bases 220 are generally welded to the rear panel 84 to maintain the vacuum in the vacuum insulated cavity 18.

The stem 38 may have a width that corresponds to a width of the slot portion 186 of the slotted feature 182. For example, the stem 38 may have a width such that the hangers 188 may be inserted into the respective slot portions 186 and translated along the slot portions 186. It is also generally contemplated that the stem 38 may have a width that coincides or differs with a width of the hanger base 220. For example, the width of the stem 38 may be less than the width of the hanger base 220, or the stem 38 may have a width coinciding with the hanger base 220 such that the hanger base 220 and the stem 38 are a single component with a single width. In such examples, the lesser width of the stem 38 relative to the width of the hanger base 220 and the width of the head 40 may assist in retaining the wire on tube condenser 20 in a static position, while also limiting or preventing the movement of the engagement plates 160.

According to various aspects, for each hanger 188, the head 40 may be integrally formed with or coupled to the stem 38. The head 40 may have a shape and/or size that coincides with or differs from the shape and size of the stem 38. For example, the head 40 may define a cylindrical shape that is coaxial with a cylindrical shape of the stem 38 with the head 40 having a width that is greater than the width of the stem 38. In such examples, the width of the head 40 may be at least partially determined by the width of the receiver portion 184 and/or the slot portion 186 of the slotted feature 182. For example, the head 40 may have a width such that the head 40 is insertable through receiving portion 184. The width of the head 40 may then be greater than the width of the slot portion 186 such that the stem 38 extends through the slot portion 186 with the head 40 on the opposing side of the respective engagement plate 160 compared to the hanger base 220, such that the engagement plates 30 are operably coupled to and interlocked with the hangers 188.

The head 40 is spaced from the rear panel 84 by the stem 38. Accordingly, the head 40 may be proximate to or distal from the rear panel 84 based on the length of the stem 38. For example, the stem 38 may have a length such that the head 40 is distal from the rear panel 84. In such examples, the distance between the head 40 and the rear panel 84 may be such that an inner surface 230 of the head 40 is configured to abut an outer surface 232 of the engagement plate 160 when the hangers 188 are inserted into the slotted features 182. The abutment between the inner surface 230 of the head 40 and the outer surface 232 of the engagement plate 160 may provide an engagement that at least partially keeps the wire on tube condenser 20 coupled to the hangers 188.

In examples where the rear panel 84 includes multiple sections with multiple thicknesses, the distance between the head 40 and the rear panel 84 may be such that an end surface 234 of the head 40 may be recessed from, flush with, or protruding relative to the opposing portion 130, 132 of the rear panel 84. For example, in examples where the wire on tube condenser 20 and the hangers 188 are coupled to the first side portion 130, which is recessed from the second side portion 132, the head 40 may be spaced from an outer surface 236 of the first side portion 130 of the rear panel 84 and the end surface 234 of the head 40 may be flush with an outer surface 238 of the second side portion 132. In this way, the hangers 188 may not protrude relative to the second side portion 132, reducing the amount or distance the wire on tube condenser 20 protrudes relative to the second side portion 132.

According to various aspects, the appliance 10 may include a plurality of brackets 250 coupled to the rear panel 84 and extending from the rear panel 84. The plurality of brackets 250 may be disposed along a width and/or a length of the rear panel 84. The plurality of brackets 250 may be disposed along a length or height of the rear panel 84 and coincide with the placement of the plurality of hangers 36. In some examples, the plurality of brackets 250 are disposed between the hangers 188. The plurality of brackets 250 may include a first set 252 that align with the first set 210 of hangers 188 and a second set 254 that aligns with the second set 212 of hangers 188. In such examples, an abutment surface 256 on each bracket 258 may align with a center point 260 of each hanger 188.

The brackets 258 can be disposed on the rear panel 84 such that the brackets 258 are coupled to the tube 122 and disposed outside of the wire grid 120. In such examples, the tube 122 may extend beyond a width of the wire grid 120 and the brackets 258 may be disposed outside of the wire grid 120 and coupled to the tube 122. In various examples, the brackets 258 can be disposed on the rear panel 84 such that the brackets 258 are coupled to the tube 122 and inward of the wire grid 120. In such examples, the wire grid 120 may include sections where the wires 124 are disposed intermittently such that spaces are defined and the brackets 258 extend through each space and engage with the tube 120. Additionally, or alternatively, it is generally contemplated that the placement of the brackets 258 may differ from the placement of the engagement plates 160. For example, the brackets 258 may be offset from the engagement plates 160. It is also generally contemplated that the brackets 188 and the wire on tube condenser 20 may define various shapes and patterns without departing from the teachings herein.

The brackets 258 may generally define an “L” shape to couple to the rear panel 84 and extend therefrom. Similar to the hangers 188, the brackets 258 are generally welded or adhered to the rear panel 84 to maintain the vacuum in the vacuum insulated cavity 18. Additionally, the brackets 258 generally each have a receiving end 262, which forms a space for receiving and supporting the tube 122 of the wire on tube condenser 180.

In various examples, one or more brackets 258 may be offset from the hangers 188. In such examples, the brackets 258 may be offset such that each abutment surface 256 of each bracket 258 is offset and not contacting the wire on tube condenser 20 when the hangers 36 are first inserted into the receiving portions 184 of the slotted features 182. As illustrated in FIG. 7, once the wire on tube condenser 20 is translated downward such that the hangers 188 are translated into the slot portion 186, the brackets 258 are positioned such that the wire grid 120 and/or the tube 122 abuts the abutment surface 256 and additional support between the wire on tube condenser 20 and the rear panel 84 is provided. This engagement between the engagement plates 160 and the hangers 188 and/or the engagement between the brackets 258 and the tube 122 is further assisted by a gravitational pull on the wire on tube condenser 20. In particular, the downward gravitational pull on the wire on tube condenser 20 is such that the engagement between the engagement plates 160 and hangers 188 and the engagement between the brackets 258 and the tube 122 is maintained.

Referring to FIGS. 2-7, the appliance 10 includes the wire on tube condenser 20 coupled to the rear panel 84. The wire on tube condenser 20 can be coupled to the rear panel 84 through engagement between the engagement plates 160 and the hangers 188 and/or by engagement between the brackets 258 and wire grid 120 or tube 122 of the wire on tube condenser 20. The wire on tube condenser 20 can extend along the rear panel 84 to increase surface area of the wire on tube condenser 20, and subsequently, heat transfer between the refrigerant and ambient air.

In the illustrated embodiment of FIG. 2, the wire on tube condenser 20 is shown extending from a bottom portion 270 of the rear panel 84 and towards the top portion 28 of the cabinet 12. In such embodiments, the placement and extension of the wire on tube condenser 20 are such that heat transfer is enhanced and operable space within the machine compartment 26 is increased. Additionally, or alternatively, while the wire on tube condenser 20 is illustrated and described as a wire on tube condenser 20, it is generally contemplated that the wire on tube condenser 20 may be one of various kinds of condensers, such as a fin and tube condenser, without departing from the teachings herein.

Referring to FIGS. 2, 3, and 7, the appliance 10 includes the machine compartment 26 that contains components of a refrigerant system 272. The machine compartment 26 is shown below the bottom portion 270 of the rear panel 84 with an inner surface 274 at least partially defined by the cabinet 12. In some examples, the top region 24 of the machine compartment 26 is at least partially defined by the bottom portion 270 of the rear panel 84 such that the machine compartment 26 is positioned below the wire on tube condenser 20. According to various aspects, the machine compartment 26 operably houses various components or portions of components of the refrigerant system 272 and the appliance 10, as provided herein.

Due to the wire on tube condenser 20 being upward of the machine compartment 26, the machine compartment 26 may be configured such that various components of the refrigerant system 272 may be optimally placed within the machine compartment 26, providing additional space between components for reducing heat transfer and vibrations between various components of the refrigerant system 272. The machine compartment 26 may be configured such that a control box 280 is disposed at one end 282 of the machine compartment 26 and a compressor 284 is disposed at an opposing end 286 of the machine compartment 26. As illustrated, a drain pan 288 is disposed above the compressor 284. A drier 290 is disposed between the control box 280 and the compressor 284 and downward of or below the wire on tube condenser 20. This positioning of the drier 290 is further from the compressor 284 than conventional configurations. The distal positioning of the drier 290 relative to the compressor 284 may be such that heat radiated from the compressor 284 may be dissipated into an environment proximate the compressor 284 and cooling capacity of the drier 290 may be maintained.

It is generally contemplated that the placement of the components of the refrigerant system 272 in the machine compartment 26 may permit greater variation in insulation of the appliance 10 proximate to the machine compartment 26. In particular, the appliance 10 may be insulated such that the regions in the bottom portion 270 of the cabinet 12 may have greater or lesser insulation, depending on which component is proximate the cabinet 12. For example, a region proximate the compressor 284 may have a greater insulation thickness than a region that is proximate the control box 280.

Referring further to FIG. 7, the machine compartment 26 may include various other elements and components for the refrigerant system 272. For example, the machine compartment 26 includes refrigerant lines 300 extending between the compressor 284 and the wire on tube condenser 20, as well as refrigerant lines 302 extending between a heat loop 304 and the wire on tube condenser 20. In various examples, due to the placement of the wire on tube condenser 20 above the machine compartment 26, the refrigerant lines 300, 302 may be sufficiently spaced (i.e., greater than about 7 mm) from the control box 280 and/or the compressor 284 such that vibrations generated by a component, such as the control box 280, are mitigated or prevented from transferring to the refrigerant lines 300, 302, which, in turn, may reduce noise emitted from the vibrations and mitigate fluid leaks that may occur due to the transferring of the vibrations. Additionally, the machine compartment 26 includes a suction line 306, a check valve 308 fluidly coupled to the suction line 306, one or more suction line heat exchangers 310, a 3-way valve 312, and drain tubes 314 extending from the machine compartment 26.

Referring to FIGS. 1-8, the appliance 10 having the wire on tube condenser 20 couplable to the rear portion 22 of the appliance 10 and above the machine compartment 26, provides for an appliance 10 with an optimally placed condenser 20 that increases thermal efficiency of the appliance 10 and usable space within the machine compartment 26. In particular, the engagement plates 30 and the hangers 188 provide for an appliance 10 with a condenser 20 that can be readily coupled to the rear panel 84 of the appliance 10 outside of the machine compartment 26. This engagement between the engagement plates 30 and the hangers 188 is such that the wire on tube condenser 20 operably couples to the rear panel 84 once the engagement occurs. Further, the placement of the wire on tube condenser 20 additionally allows for optimal spacing of various components of the refrigerant system 272 within the machine compartment 26, thus improving thermal efficiency within the machine compartment 26.

According to various examples, the wire on tube condenser 20 with the engagement plates 30 that engage the hangers 188 can be used in various appliances. These appliances can include, but are not limited to, refrigerators, freezers, coolers, dishwashers, and other similar appliances and fixtures within household and commercial settings.

Referring further to FIGS. 1-8, the present disclosure provides for a variety of advantages. For example, the coupling of the wire on tube condenser 20 to the rear panel 84 via engagement between the engagement plates 30 and the hangers 188 and/or engagement between the brackets 258 and the wire on tube condenser 20 provides for various engagements that can be utilized to couple the wire on tube condenser 20 to the cabinet 12. Similarly, these engagements provide for increased efficiency in manufacture of the appliance 10, as the wire on tube condenser 20 can be coupled to the rear panel 84 with minimal manufacturing steps. Additionally, the coupling of the wire on tube condenser 20 on one or more of the portions 130, 132 of the rear panel 84 provides for the implementation of multiple panel thicknesses and insulation thicknesses along the rear panel 84, which in turn, provide for efficient thermal management and increased space within the appliance 10. Similarly, the implementation of multiple panel thicknesses, as well as multiple lengths of the hangers 188, permits the wire on tube condenser 20 to be positioned relative to external cabinetry such that a gap and thermal dissipation are maintained. Further still, the use of a wire on tube condenser 20, in particular, permits the effective heat dissipation of coolant from the condenser 20 without the use of a condenser fan, such as in a microchannel condenser, while also reduces space in the machine compartment 26 and energy consumption by the refrigerant system 272.

The placement of the wire on tube condenser 20 above the machine compartment 26 also provides for more optimal placement of components of the refrigerant system 272 within the machine compartment 26. In particular, the removal of the wire on tube condenser 20 from the machine compartment 26 can be such that components of the refrigerant system 272 can be spaced out and radiation between various components reduced. For example, the drier 290 can be spaced apart from the compressor 284 such that cooling capacity of the drier 290 is maintained. Additionally, the increased space permits the refrigerant lines 300, 302 to be spaced apart from the control box 280 such that vibrations and rattling are reduced in the machine compartment 26. Further, the drain pan 288 can be moved from adjacent the compressor 284, which can be found in conventional appliances, to above the compressor 284 to increase lateral spacing between components as well as increase a size of the drain pan used. Further, the increased space also increases servicing of the machine compartment 26 as an increased space between each component increases accessibility. Additional benefits or advantages of using this appliance 10 may also be realized and/or achieved.
