[0013] Referring to FIGS. 1-4, a refrigeration appliance 10 includes a cabinet 12, a refrigeration door 14, and a freezer door or drawer 16. The cabinet 12 includes a vacuum insulated structure 18 that at least partially defines a refrigeration compartment 20 and a freezer compartment 22. The refrigeration appliance 10 can maintain an air temperature within the refrigeration compartment 20 above the freezing point of water but less than the room temperature, such as a temperature within a range of from 2 °C to 4 °C. The air temperature within the refrigeration compartment 20 thus can prolong shelf-life of a food item 24 disposed within the refrigeration compartment 20. The refrigeration appliance 10 can maintain an air temperature within the freezer compartment 22 below the freezing point of water, such as a temperature within a range of from -18 °C to -23 °C. The refrigeration appliance 10 can be of the built-in variety, as in the illustrated embodiments, where the cabinet 12 is configured to be recessed behind cabinetry (not illustrated) or of the stand-alone variety. In embodiments where the refrigeration appliance 10 is of the stand-alone variety, refrigeration appliance 10 can include a cover (not illustrated) over the cabinet 12 that is aesthetically pleasing.
[0014] The refrigeration door 14 is coupled to the cabinet 12, such as via one or more hinges 26 that are attached to both the refrigeration door 14 and the cabinet 12. The refrigeration door 14 is manipulable to, from, and between a closed position 28 (see FIG. 1) and an open position 30 (see FIG. 2). The refrigeration door 14 can include a handle 32 to facilitate a user manipulating the refrigeration door 14 accordingly. In the closed position 28, the refrigeration door 14 denies access to the refrigeration compartment 20 from an external environment 34. For example, the refrigeration door 14 covers an opening 36 into the refrigeration compartment 20 in the closed position 28. In the open position 30, the refrigeration door 14 allows access to the refrigeration compartment 20 from the external environment 34. For example, the refrigeration door 14, in the open position 30, sufficiently reveals the opening 36 for the user to access the refrigeration compartment 20 from the external environment 34.
[0015] The freezer door or drawer 16 is coupled to the cabinet 12 as well. In embodiments where the refrigeration appliance 10 includes the freezer door (not separately illustrated), the freezer door can be coupled to the cabinet 12 via hinges 26. In embodiments, such as those illustrated, where the refrigeration appliance 10 includes the freezer drawer 16, the freezer drawer 16 can be coupled to the cabinet 12 via a track system 38. The freezer door or drawer 16 is manipulable to, from, and between a closed position 28 and an open position 30. In the closed position 28, the freezer door, if included, denies access to the freezer compartment 22 from the external environment 34. For example, the freezer door covers an opening 36 that the cabinet 12 forms into the freezer compartment 22. If instead, as illustrated, the freezer drawer 16 is included, a storage compartment 40 of the freezer drawer 16 is disposed within the freezer compartment 22 and the freezer drawer 16 covers the opening 36 into the freezer compartment 22. A food item 24 can be disposed within the storage compartment 40 of the freezer drawer 16. In the open position 30, the freezer door, if included, does allow access through the opening 36 into the freezer compartment 22 from the external environment 34. If instead, as illustrated, the freezer drawer 16 is included, in the open position 30, the storage compartment 40 of the freezer drawer 16 is at least partially withdrawn from the freezer compartment 22 and accessible to the user from the external environment 34. The freezer door or drawer 16 can include a handle 42 to assist the user in manipulating the freezer door or drawer 16.
[0016] Referring additionally to FIGS. 5-9, in embodiments, the vacuum insulated structure 18 includes a refrigeration inner liner 44, a freezer inner liner 46, and an outer wrapper 48. The refrigeration inner liner 44 at least partially defines the refrigeration compartment 20. For example, the refrigeration inner liner 44 can include a top wall 50, a bottom wall 52, a side wall 54, a side wall 56, and a rear wall 58. The top wall 50 and the bottom wall 52 oppose each other. The side wall 54 and the side wall 56 oppose each other. The rear wall 58 opposes the refrigeration door 14 when the refrigeration door 14 is in the closed position 28. The top wall 50, the bottom wall 52, the side walls 54, 56, and the rear wall 58 bound the refrigeration compartment 20. The refrigeration inner liner 44 can be made of a plastic material or welded sheet metal, amount other possibilities.
[0017] The freezer inner liner 46 at least partially defines the freezer compartment 22. For example, the freezer inner liner 46 can include a top wall 60, a bottom wall 62, a side wall 64, a side wall 66, and a rear wall 68. The top wall 60 and the bottom wall 62 oppose each other. The side wall 64 and the side wall 66 oppose each other. The rear wall 68 opposes the freezer door or drawer 16 when the freezer door or drawer 16 is in the closed position 28. The top wall 60, the bottom wall 62, the side walls 64, 66, and the rear wall 68 bound the freezer compartment 22. The freezer inner liner 46 can be made of a plastic material or welded sheet metal, amoung other possibilities.
[0018] In embodiments, such as that illustrated, the refrigeration inner liner 44 is disposed above the freezer inner liner 46. However, the refrigeration inner liner 44 could be disposed below the freezer inner liner 46. Alternatively, the refrigeration inner liner 44 and the freezer inner liner 46 could be disposed side-by-side.
[0019] The outer wrapper 48 at least partially envelopes both the refrigeration inner liner 44 and the freezer inner liner 46. For example, in the illustrated embodiments, the outer wrapper 48 includes a top wall 70, a bottom wall 72, a side wall 74, a side wall 76, and a rear wall 78. The top wall 70 and the bottom wall 72 oppose each other. The side walls 74, 76 oppose each other. The top wall 70 is disposed above the top wall 50 of the refrigeration compartment 20. The bottom wall 72 is disposed below the bottom wall 52 of the refrigeration compartment 20. Due to the orientation of the refrigeration inner liner 44 being above the freezer inner liner 46, the side wall 74 of the outer wrapper 48 is disposed laterally outward from the side wall 54 of the refrigeration inner liner 44 and the side wall 64 of the freezer inner liner 46. Likewise, the side wall 76 of the outer wrapper 48 is disposed laterally outward from the side wall 56 of the refrigeration inner liner 44 and the side wall 66 of the freezer inner liner 46. The refrigeration inner liner 44 and the freezer inner liner 46 are both disposed elevationally between the top wall 70 and the bottom wall 72 of the outer wrapper 48. The refrigeration inner liner 44 and the freezer inner liner 46 are both disposed between the side wall 74 and the side wall 76 of the outer wrapper 48. The rear wall 78 of the outer wrapper 48 is disposed rearward of the rear wall 58 of the refrigeration inner liner 44 and the rear wall 68 of the freezer inner liner 46.
[0020] The outer wrapper 48 is separated from both the refrigeration inner liner 44 and the freezer inner liner 46 by a contiguous space 80. For example, in the illustrated embodiments, the contiguous space 80 separates (i) the top wall 70 of the outer wrapper 48 from the top wall 50 of the refrigeration inner liner 44, (ii) the bottom wall 72 of the outer wrapper 48 from the bottom wall 62 of the freezer inner liner 46, (iii) the side wall 74 of the outer wrapper 48 from the side wall 54 of the refrigeration inner liner 44 and the side wall 64 of the freezer inner liner 46, and (iv) the side wall 76 of the outer wrapper 48 from the side wall 56 of the refrigeration inner liner 44 and the side wall 66 of the freezer inner liner 46.
[0021] Similarly, the contiguous space 80 separates the refrigeration inner liner 44 from the freezer inner liner 46. For example, in the illustrated embodiments, the contiguous space 80 separates the bottom wall 52 of the refrigeration inner liner 44 from the top wall 60 of the freezer inner liner 46.
[0022] The contiguous space 80 of the vacuum insulated cabinet 12 separating the outer wrapper 48, the refrigeration inner liner 44, and the freezer inner liner 46 from each other has an air pressure that is less than atmospheric air pressure. The reduced air pressure within the contiguous space 80 is achieved by evacuating air from the contiguous space 80 and sealing the vacuum insulated structure 18. The reduced air pressure reduces thermal transfer from the external environment 34 through the vacuum insulated structure 18 and into the refrigeration compartment 20 and the freezer compartment 22 compared to if the air pressure was not reduced. The vacuum insulated structure 18 can further include insulation media 82 (e.g., fumed silica) within the contiguous space 80 to further reduce thermal transfer and to help maintain form of the vacuum insulated structure 18.
[0023] Referring additionally to FIGS. 10-13, the cabinet 12 further includes a conduit system 84. The conduit system 84 is in fluid communication with both the refrigeration compartment 20 and the freezer compartment 22. The conduit system 84 allows air to flow from the freezer compartment 22, through the freezer inner liner 46, through the contiguous space 80, through the outer wrapper 48, alongside the outer wrapper 48, through the contiguous space 80 again, and then through the refrigeration inner liner 44 into the refrigeration compartment 20. Similarly, the conduit system 84 allows air to flow from the refrigeration compartment 20, through the refrigeration inner liner 44, through the contiguous space 80, through the outer wrapper 48, alongside the outer wrapper 48, through the contiguous space 80 again, and then through the freezer inner liner 46 into the freezer compartment 22.
[0024] To accommodate airflow between the refrigeration compartment 20 and the freezer compartment 22 through the conduit system 84, the refrigeration inner liner 44 comprises an aperture 86 that is aligned with a first aperture 88 of the outer wrapper 48. The conduit system 84 extends through the aperture 86 and the first aperture 88 to be in fluid communication with the refrigeration compartment 20. Similarly, the freezer inner liner 46 comprises an aperture 90 that is aligned with a second aperture 92 of the outer wrapper 48. The conduit system 84 extends through the aperture 90 and the second aperture 92 to be in fluid communication with the freezer compartment 22. "Aligned" here can mean alignment of the aperture 86 and first aperture 88, and of the aperture 90 and the second aperture 92, horizontally forward 94 to rearward 96, but need not be. Any straight-line alignment suffices.
[0025] Referring additionally to FIGS. 14 and 15, in embodiments, the vacuum insulated structure 18 further includes a refrigeration passthrough 98. The refrigeration passthrough 98 is disposed within the aperture 86 of the refrigeration inner liner 44 and first aperture 88 of the outer wrapper 48. An outer surface 100 of the refrigeration passthrough 98 forms an airtight seal against both the refrigeration inner liner 44 and the outer wrapper 48. The airtight seal prevents the air pressure within the contiguous space 80 from equalizing with the atmospheric air pressure. The refrigeration passthrough 98 extends through the contiguous space 80 between the aperture 86 and first aperture 88. In such embodiments, the refrigeration passthrough 98 includes an aperture 102 that may be part of the conduit system 84 to the extent that airflow through the aperture 102 contacts the refrigeration passthrough 98. The conduit system 84 thus maintains fluid communication with the refrigeration compartment 20.
[0026] In embodiments, the vacuum insulated structure 18 further includes a freezer passthrough 104. The freezer passthrough 104 and the refrigeration passthrough 98 can be identical and thus do not need to be individually illustrated. The freezer passthrough 104 is disposed within the aperture 90 of the freezer inner liner 46 and the second aperture 92 of the outer wrapper 48. An outer surface 107 of the freezer passthrough 104 forms an airtight seal against both the freezer inner liner 46 and the outer wrapper 48. The airtight seal prevents the air pressure within the contiguous space 80 from equalizing with the atmospheric air pressure. The freezer passthrough 104 extends through the contiguous space 80 between the aperture 90 and the second aperture 29. In such embodiments, the freezer passthrough 104 includes an aperture 108 that may be part of the conduit system 84 to the extent that airflow through the aperture 108 contacts the freezer passthrough 104. The conduit system 84 thus maintains fluid communication with the freezer compartment 22.
[0027] In embodiments, the conduit system 84 includes a tube 110. The tube 110 has a first end 103 and a second end 105. The first end 103 can terminate within the aperture 102 of the refrigeration passthrough 98, as illustrated, or proximate the refrigeration passthrough 98 within the refrigeration compartment 20. The second end 105 can terminate within the aperture 108 of the freezer passthrough 104, as illustrated, or proximate the freezer passthrough 104 within the freezer compartment 22. At least in part because of the conduit system 84, as the refrigeration door 14 is manipulated from the closed position 28 to the open position 30, air flows (i) from the freezer compartment 22 into the second end 105 of the tube 110 (either directly or via the aperture 108 through the freezer passthrough 104), (ii) from the second end 105 of the tube 110 toward the first end 103 of the tube 110, and (iii) from the first end 103 of the tube 110 into the refrigeration compartment 20 (either directly or via the aperture 102 of the refrigeration passthrough 98). The user pulling the refrigeration door 14 to the open position 30 pulls air from the freezer compartment 22 toward the refrigeration compartment 20 via the conduit system 84 including the tube 110. Similarly, as the freezer door or drawer 16 is manipulated from the closed position 28 to the open position 30, air flows (i) from the refrigeration compartment 20 into the first end 103 of the tube 110 (either directly or via the aperture 102 through the refrigeration passthrough), (ii) from the first end 103 of the tube 110 toward the second end 105 of the tube 110, and (iii) from the second end 105 of the tube 110 into the freezer compartment 22 (either directly or via the aperture 108 of the freezer passthrough 104). The user pulling the freezer door or drawer 16 to the open position 30 pulls air from the refrigeration compartment 20 toward the freezer compartment 22 via the conduit system 84 including the tube 110.
[0028] In embodiments, the cabinet 12 further includes a refrigeration evaporator 106. The refrigeration evaporator 106 is disposed within the refrigeration compartment 20. As the refrigeration evaporator 106 is utilized for a refrigeration cycle to withdraw heat from the refrigeration compartment 20, water condenses upon the refrigeration evaporator 106. The condensed water falls from the refrigeration evaporator 106 because of the force of gravity. The water can be collected with the incorporation of a funnel 109 disposed under the refrigeration evaporator 106.
[0029] The conduit system 84 can include a refrigeration conduit 110A positioned to direct the condensate so collected from the refrigeration evaporator 106 to outside of the refrigeration compartment 20. More particularly, in embodiments, such as those illustrated, the refrigeration conduit 110A includes a first portion 112, a second portion 114, and a body 116 disposed between the first portion 112 and the second portion 114. The first portion 112 of the refrigeration conduit 110A is positioned to accept condensate collected from the refrigeration evaporator 106. For example, the first portion 112 can be fluidly coupled to the funnel 109 elevationally below the refrigeration evaporator 106. The body 116 of the refrigeration conduit 110A extends from the first portion 112, through the aperture 86 of the refrigeration inner liner 44, through the contiguous space 80 between the refrigeration inner liner 44 and the outer wrapper 48, and through the first aperture 88 of the outer wrapper 48. The second portion 114 is disposed external to an outer surface 118 of the outer wrapper 48. For example, the second portion 114 can be disposed rearward 96 of the outer wrapper 48 or beneath the outer wrapper 48, among other options.
[0030] In embodiments, the refrigeration conduit 110A extends through the refrigeration passthrough 98. The refrigeration passthrough 98 can include an aperture 120 for the refrigeration conduit 110A. The first portion 112 of the refrigeration conduit 110A can accept the condensate collected from the refrigeration evaporator 106 within the aperture 120 of the refrigeration passthrough 98 or proximate the refrigeration passthrough 98 within the refrigeration compartment 20. The body 116 of the refrigeration conduit 110A then extends away from the first portion 112 within the refrigeration passthrough 98, such as rearward 96. The body 116 extends along the outer wrapper 48 external to the outer surface 118 thereof, such as downward 122, so that the force of gravity causes the condensate to flow downward 122 toward the second portion 114. The second portion 114 can be disposed elevationally below the first portion 112.
[0031] In embodiments, the cabinet 12 further includes a freezer evaporator 124. The freezer evaporator 124 is disposed within the freezer compartment 22. As the freezer evaporator 124 is utilized for a refrigeration cycle to withdraw heat from the freezer compartment 22, water condenses upon the freezer evaporator 124. The condensed water falls from the freezer evaporator 124 because of the force of gravity. The water can be collected with the incorporation of a funnel 126 disposed under the freezer evaporator 124. The refrigeration appliance 10 can further include a defrosting mechanism (e.g., a defrost heater, not illustrated) to facilitate melting of condensate that has frozen upon the freezer evaporator 124.
[0032] The conduit system 84 can include a freezer conduit 128 positioned to direct the condensate so collected from the freezer evaporator 124 to outside of the freezer compartment 22. More particularly, in embodiments, such as those illustrated, the freezer conduit 128 includes a first portion 130, a second portion 132, and a body 134 disposed between the first portion 130 and the second portion 132. The first portion 130 of the freezer conduit 128 is positioned to accept condensate collected from the freezer evaporator 124. For example, the first portion 130 can be fluidly coupled to the funnel 126 elevationally below the freezer evaporator 124. The body 134 of the freezer conduit 128 extends from the first portion 130, through the aperture 90 of the freezer inner liner 46, through the contiguous space 80 between the freezer inner liner 46 and the outer wrapper 48, and through the second aperture 92 of the outer wrapper 48. The second portion 132 is disposed external to the outer surface 118 of the outer wrapper 48. For example, the second portion 132 can be disposed rearward 96 of the outer wrapper 48 or beneath the outer wrapper 48, among other options.
[0033] In embodiments, the freezer conduit 128 extends through the freezer passthrough 104. The freezer passthrough 104 can include an aperture 136 for the freezer conduit 128. The first portion 130 of the freezer conduit 128 can accept the condensate collected from the freezer evaporator 124 within the aperture 136 of the freezer passthrough 104 or proximate the freezer passthrough 104 within the freezer compartment 22. The body 134 of the freezer conduit 128 then extends away the first portion 130 within the freezer passthrough 104, such as rearward 96. The body 134 extends along the outer wrapper 48 external to the outer surface 118 thereof, such as downward 122, so that the force of gravity causes the condensate to flow downward 122 toward the second portion 132. The second portion 132 can be disposed elevationally below the first portion 130.
[0034] The refrigeration conduit 110A and the freezer conduit 128 of the conduit system 84 are fluidly coupled external to the outer surface 118 of the outer wrapper 48. For example, the conduit system 84 can include pipe fittings 138 such as an elbow 138a and a tee 138b to fluidly connect the refrigeration conduit 110A and the freezer conduit 128. In embodiments, the refrigeration conduit 110A and the freezer conduit 128 become fluidly coupled elevationally below the second aperture 92 of the outer wrapper 48.
[0035] In embodiments, the conduit system 84 further includes a drain conduit 140. The drain conduit 140 is fluidly coupled to both the refrigeration conduit 110A and the freezer conduit 128. For example, the drain conduit 140 can include a first end 142 that is fluidly coupled to the tee, which places the first end 142 of the drain conduit 140 in fluid communication with both the second portion 132 of the freezer conduit 128 and the second portion 114 of the refrigeration conduit 110A.
[0036] In embodiments, the cabinet 12 further includes a drain pan 144. The conduit system 84 is further in fluid communication with the drain pan 144. For example, the drain conduit 140 can include a second end 146 in fluid communication with the drain pan 144. The drain pan 144 can be elevationally below the conduit system 84, and the second end 146 of the drain conduit 140 disposed elevationally below the first end 142 of the drain conduit 140, so that condensate flows from the conduit system 84 into the drain pan 144. The drain pan 144 can be disposed within a machine room 148 of the cabinet 12, along with refrigeration cycle components such as a compressor 150. To facilitate gravitationally induced flow of condensate from the conduit system 84 into the drain pan 144, the vacuum insulated structure 18 can be disposed above the machine room 148 and thus the drain pan 144. The conduit system 84 can terminate within the machine room 148 with the second end 146 of the drain conduit 140 be disposed elevationally above the drain pan 144. Condensate thus flows out of the second end 146 of the drain conduit 140 and into the drain pan 144.
[0037] As the refrigeration door 14 is manipulated from the closed position 28 to the open position 30, air flows (i) from the freezer compartment 22 and into the first portion 130 of the freezer conduit 128, (ii) from the first portion 130 of the freezer conduit 128 toward the second portion 132 of the freezer conduit 128, (iii) from the second portion 132 of the freezer conduit 128 to the second portion 114 of the refrigeration conduit 110A, (iv) from the second portion 114 of the refrigeration conduit 110A to the first portion 112 of the refrigeration conduit 110A, and (v) from the first portion 112 of the refrigeration conduit 110A into the refrigeration compartment 20. Similarly, as the refrigeration door 14 is manipulated from the closed position 28 to the open position 30, air flows (i) from the external environment 34 into the second end 146 of the drain conduit 140, (ii) from the second end 146 of the drain conduit 140 toward first end 142 of the drain conduit 140, (iii) from the first end 142 of the drain conduit 140 to the second end 105 of the refrigeration conduit 110A, (iv) from the second end 105 of the refrigeration conduit 110A towards the first end 103 of the refrigeration conduit 110A, and (v) from the second end 105 of the refrigeration conduit 110A and into the refrigeration compartment 20.
[0038] As the freezer door or drawer 16 is manipulated from the closed position 28 to the open position 30, air flows (i) from the refrigeration compartment 20 and into the first portion 112 of the refrigeration conduit 110A, (ii) from the first portion 112 of the refrigeration conduit 110A toward the second portion 114 of the refrigeration conduit 110A, (iii) from the second portion 114 of the refrigeration conduit 110A to the second portion 132 of the freezer conduit 128, (iv) from the second portion 132 of the freezer conduit 128 to the first portion 130 of the freezer conduit 128, and (v) from the first portion 130 of the freezer conduit 128 into the freezer compartment 22. Similarly, as the freezer door or drawer 16 is manipulated from the closed position 28 to the open position 30, air flows (i) from the external environment 34 into the second end 146 of the drain conduit 140, (ii) from the second end 146 of the drain conduit 140 toward first end 142 of the drain conduit 140, (iii) from the first end 142 of the drain conduit 140 to the second end 105 of the freezer conduit 128, (iv) from the second end 105 of the freezer conduit 128 towards the first end 103 of the freezer conduit 128, and (v) from the second end 105 of the freezer conduit 128 and into the freezer compartment 22.
[0039] The conduit system 84 can include the tube 110, but not the refrigeration conduit 110A fluidly coupled to the freezer conduit 128, to direct airflow from the freezer compartment 22 into the refrigeration compartment 20 as the refrigeration door 14 is moved to the open position 30 or from the refrigeration compartment 20 into the freezer compartment 22 as the freezer door or drawer 16 is moved to the open position 30. Alternatively, the conduit system 84 can include the refrigeration conduit 110A fluidly coupled to the freezer conduit 128, but not the tube 110, to direct airflow from the freezer compartment 22 into the refrigeration compartment 20 as the refrigeration door 14 is moved to the open position 30 or from the refrigeration compartment 20 into the freezer compartment 22 as the freezer door or drawer 16 is moved to the open position 30. As another alternative, the conduit system 84 can include both the tube 110 and the refrigeration conduit 110A fluidly coupled to the freezer conduit 128 to direct airflow from the freezer compartment 22 into the refrigeration compartment 20 as the refrigeration door 14 is moved to the open position 30 or from the refrigeration compartment 20 into the freezer compartment 22 as the freezer door or drawer 16 is moved to the open position 30. The drawings include both embodiments simultaneously for ease of description, but the refrigeration appliance 10 could include just one of the embodiments to the exclusion of the other. Note that in the instances where the refrigeration appliance 10 includes the tube 110 but not the refrigeration conduit 110A fluidly coupled to the freezer conduit 128, the refrigeration appliance 10 can additionally include the refrigeration conduit 110A and the freezer conduit 128 in separate fluid communication with the drain pan 144. Incorporating the conduit system 84 with the refrigeration conduit 110A fluidly coupled to the freezer conduit 128 but not the tube 110 may be advantageous to decrease the number of apertures (such as eliminating apertures 102, 108) through the refrigeration passthrough 98 and the freezer passthrough 104, because the apertures 136, 120 for the freezer conduit 128 and the refrigeration conduit 110A, respectively, may need to be included anyway to drain condensate from freezer evaporator 124 and the refrigeration evaporator 106.
[0040] The embodiments of the conduit system 84 of the present disclosure address the problem described in the Background, because, as the user pulls the refrigeration door 14 toward the open position 30, the conduit system 84 allows airflow from the freezer compartment 22 to the refrigeration compartment 20. The additional airflow into the refrigeration compartment 20 lessens the air pressure differential between the air within the refrigeration compartment 20 and atmospheric air pressure. The user thus uses a lesser pulling force to move the refrigeration door 14 to the open position 30 compared to if the refrigeration appliance 10 did not include such a conduit system 84.
[0041] In addition, the conduit system 84 may reduce moisture imbalance between the refrigeration compartment 20 and the freezer compartment 22 compared to if no conduit system 84 was included to allow air to flow between the refrigeration compartment 20 and the freezer compartment 22. The reduction in the moisture imbalance could mean a reduced relative humidity within the refrigeration compartment 20. The reduced relative humidity reduces the volume of insulation needed to cover refrigeration cycle lines within the refrigeration compartment 20, which leads to increased capacity for the refrigeration compartment 20 to hold food items 24.
