[0024] The present invention will be described in detail below in conjunction with the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional changes made by a person skilled in the art based on these embodiments are all within the scope of protection of the present invention.

[0025] It should be understood that the terms such as “having”, “including” and “comprising” used herein do not exclude the existence or addition of one or more other elements or combinations thereof.

[0026] It should be understood that the terms used herein, such as "upper", "lower", "outer", "inner", etc., indicating spatial relative positions are used for the purpose of convenience to describe the relationship of one unit or feature relative to another unit or feature as shown in the drawings. The spatial relative position terms may be intended to include different orientations of the device in use or operation other than the orientation shown in the drawings.

[0027] Reference Figure 1 and Figure 2 As shown, a preferred embodiment of the utility model provides a refrigerator, including a refrigeration system, wherein the refrigeration system includes a compressor, a condenser, and an evaporator 10 connected by a pipeline, wherein the pipeline includes an air inlet pipe 21 connecting the evaporator 10 and the condenser, and a return air pipe 22 connecting the evaporator 10 and the compressor. In this embodiment, the refrigerant first flows from the compressor to the condenser, and after the refrigerant in the pipeline flows through the condenser for heat exchange, it flows into the evaporator 10 through the capillary tube and the air inlet pipe 21, and after the evaporator 10 performs heat exchange, it flows from the return air pipe 22 to the compressor, completing the circulation of the refrigerant in the pipeline.

[0028] Further, the refrigerator includes a packaging structure 30, wherein the packaging structure 30 has an evaporation chamber 31 and a drain port 32 connected to the evaporation chamber 31. In this embodiment, the evaporator 10 is disposed in the evaporation chamber 31, so as to exchange heat with the gas in the evaporation chamber 31. The drain port 32 is used to discharge water in the evaporation chamber 31, such as defrost water. The drain port 32 is connected to the drain pipe 60, so that the water discharged from the drain port 32 is led out, for example, to the evaporation dish of the compressor.

[0029] Specifically, the evaporation chamber 31 includes a first space 311 for accommodating the evaporator 10 and a second space 312 connecting the first space 311 and the drain port 32. In this embodiment, the air outside the refrigerator flows to the drain port 32 through the drain pipe 60, and flows into the evaporation chamber 31 through the drain port 32. When the air outside the refrigerator flows into the evaporation chamber 31 through the drain port 32, it first flows into the second space 312, and then flows into the first space 311 after passing through the second space 312.

[0030] Furthermore, at least a portion of the air inlet pipe 21 and / or the air return pipe 22 is exposed in the second space 312. In this embodiment, by exposing at least a portion of the air inlet pipe 21 and / or the air return pipe 22 in the second space 312, the gas flowing into the evaporation chamber 31 from the drain port 32 can be cooled, and the gas flows to the first space 311 after being cooled in the second space 312, thereby reducing frost generated on the components in the first space 311 and ensuring normal refrigeration of the refrigerator.

[0031] In addition, when the hotter air outside the refrigerator flows into the second space 312, frost will form on the air inlet pipe 21 and / or the air return pipe 22 exposed in the second space 312, thereby preventing the hot air from flowing into the first space 311. In addition, when the evaporator 10 is defrosted, the heat generated by the defrosting heating wire can defrost the air inlet pipe 21 and / or the air return pipe 22 exposed in the second space 312.

[0032] Mate Reference Figure 3 and Figure 4 As shown, further, the air inlet pipe 21 has a first precooling portion 211 exposed in the second space 312, and the air return pipe 22 has a second precooling portion 221 exposed in the second space 312. In this embodiment, it is preferred that the air inlet pipe 21 (i.e., the first precooling portion 211) located in the second space 312 is completely exposed, and the air return pipe 22 (i.e., the second precooling portion 221) located in the second space 312 is completely exposed. Both the first precooling portion 211 and the second precooling portion 221 are exposed in the second space 312, accelerating the cooling of the air flowing into the second space 312 through the drain port 32, and reducing the temperature of the gas flowing out of the second space 312 and flowing into the first space 311.

[0033] Furthermore, the first pre-cooling section 211 and the second pre-cooling section 221 are arranged side by side. Figure 4 The first precooling part 211 and the second precooling part 221 are parallel to each other and spaced apart from each other, and the lengths of the first precooling part 211 and the second precooling part 221 along the axis direction are the same. Since the first precooling part 211 and the second precooling part 221 are arranged side by side, heat exchange can be performed between the first precooling part 211 and the second precooling part 221, thereby reducing the energy consumption of the refrigerator.

[0034] Furthermore, the refrigerator further includes an evaporator fan 40, at least part of which is exposed in the first space 311. In this embodiment, the evaporator fan 40 accelerates the gas flow in the evaporation chamber 31. Preferably, the evaporator fan 40 is entirely located in the first space 311, so as to be away from the second space 312, and is not easily exposed to the hot air flowing in from the drain port 32, thereby reducing the amount of frost on the evaporator fan 40 and ensuring the normal operation of the evaporator fan 40.

[0035] Furthermore, the evaporation fan 40 and the drain port 32 are located on the same side of the evaporation chamber 31, and the evaporator 10 is located on the opposite side of the evaporation chamber 31. In this embodiment, since the temperature at the evaporator 10 in the first space 311 is lower than that at the evaporation fan 40, the temperature difference between the air temperature flowing from the second space 312 into the first space 311 and the temperature at the evaporation fan 40 is relatively small, so that the gas flowing out of the first space 311 is not prone to frost when it first flows to the evaporation fan 40, and then flows to the evaporator 10 to avoid frost caused by a large temperature difference.

[0036] Furthermore, the refrigerator further includes an evaporation fan 40 disposed in the evaporation chamber 31. In this embodiment, the evaporation fan 40 may be disposed in the first space 311 and / or the second space 312.

[0037] Furthermore, the first precooling part 211 and the second precooling part 221 are located between the evaporation fan 40 and the drain port 32. In this embodiment, the air flowing into the drain port 32 flows directly to the first precooling part 211 and the second precooling part 211, and after being cooled by the first precooling part 211 and the second precooling part 211, flows directly to the evaporation fan 40, which facilitates the gas flow in the second space 312, reduces the amount of frost at the first precooling part 211 and the second precooling part 211, and ensures the normal operation of the evaporation fan 40.

[0038] In a different embodiment not shown, the air inlet pipe 21 further has a first connection portion connected to the first precooling portion, the air return pipe 22 further has a second connection portion connected to the second precooling portion, the pipeline further includes a first insulation sleeve disposed on the first connection portion and a second insulation sleeve disposed on the second connection portion, and the first connection portion and the second connection portion are located in the evaporation chamber 31. In this embodiment, the air inlet pipe 21 located in the second space 312 is only partially exposed, that is, the first precooling portion is exposed and the first connection portion is not exposed; the air return pipe 22 located in the second space 312 is only partially exposed, that is, the second precooling portion is exposed and the second connection portion is not exposed.

[0039] Considering that the cross-sectional area of ​​the drain port 32 is small, the air flowing into the second space 312 from the drain port 32 is limited, and the air inlet pipe 21 and the air return pipe 22 in the second space 312 are only partially exposed, and the other parts of the air inlet pipe 21 and the air return pipe 22 are provided with insulation sleeves, thereby ensuring that the air flowing into the second space 312 from the drain port 32 is cooled while reducing the amount of frost on the air inlet pipe 21 and the air return pipe 22, and preventing excessive frost from extending to the evaporation fan. Insulation sleeves are also provided on the air inlet pipe 21 and the air return pipe 22 outside the evaporation chamber 31 to prevent the generation of condensed water.

[0040] Specifically, the package structure 30 also has an air outlet 33 connected to the evaporation chamber 31. In this embodiment, the package structure 30 also has an air return port 36 connected to the evaporation chamber 31, and the package structure 30 can independently provide cooling to any room of the refrigerator, that is, a circulating air path is formed in the room through the air outlet 33 and the air return port 36.

[0041] Furthermore, the evaporation fan 40 has an air outlet 401 and an air inlet 402, and the air outlet 401 is opposite to the air outlet 33. In this embodiment, the evaporation fan 40 is fixed in the evaporation chamber 31 in a vertical manner. After being cooled, the air flowing into the second space 312 from the drain port 32 flows directly to the side of the evaporation fan 40, and does not flow directly to the air inlet 402, so as to avoid affecting the temperature at the air inlet 402.

[0042] Furthermore, the air inlet 402 is opposite to the evaporator 10. In this embodiment, the air inlet 402 is opposite to the evaporator 10, ensuring that the temperature of air flowing into the air inlet 402 and out of the air outlet 401 is relatively low, thereby meeting the refrigeration requirement.

[0043] In a different embodiment not shown, the evaporation fan 40 has an air inlet, which is opposite to the inner bottom wall of the evaporation chamber 31. In this embodiment, the evaporation fan 40 is fixed in the evaporation chamber 31 by hoisting, that is, the air inlet 402 faces downward. Similarly, the air flowing into the second space 312 from the drain port 32 flows directly to the side of the evaporation fan 40 after being cooled, and does not flow directly to the air inlet 402, so as to avoid affecting the temperature at the air inlet 402.

[0044] Mate Reference Figure 5 and Figure 6 As shown, specifically, the packaging structure 30 includes a water receiving tray 34 forming the drain port 32 and the air outlet 33, and the water receiving tray 34 includes a bottom wall 341 and a side wall 342 connected to the periphery of the bottom wall 341. In this embodiment, the water receiving tray 34 is configured as a dish-shaped structure with an open top, for receiving water formed in the evaporation chamber 31, such as defrosting water, and converging it at the drain port 32 and discharging it.

[0045] Furthermore, the drain port 32 and the air outlet 33 are located on opposite sides of the side wall 342. In this embodiment, the drain port 32 and the air outlet 33 are arranged opposite to each other, which can reduce the influence of the air flowing into the drain port 32 on the air outlet 33.

[0046] Furthermore, the drain port 32 and the air outlet 33 are located on the same side of the water receiving pan 34. In this embodiment, the drain port 32 and the air outlet 33 are located on the same side, that is, the side away from the evaporator 10, so as to prevent the evaporator 10 from being directly connected to the drain port 32, reduce the frosting area on the evaporator 10, and thus ensure the refrigeration of the evaporator 10. The drain port 32 and the air outlet 33 are located on the side of the water receiving pan 34 with a lower horizontal height, so as to facilitate the warm discharge of the defrost water. The air outlet 33 is higher than the drain port 32, so as to prevent the defrost water from flowing out of the air outlet 33.

[0047] Specifically, the refrigerator further comprises a box body, the box body comprises an inner liner 51 forming a storage space, the packaging structure 30 comprises a shell 35 forming the evaporation chamber 31, and the shell 35 is exposed in the storage space. In this embodiment, the shell 35 is exposed to the storage space, and can provide cooling capacity for the storage space through the air outlet 33 and the return air outlet 36.

[0048] Specifically, the housing 35 cooperates with the water receiving tray 34 . The housing 35 includes an upper shell 351 and a lower shell 352 that are connected to each other. The upper shell 351 and the lower shell 352 are connected to each other to limit the movement of the water receiving tray 34 .

[0049] Furthermore, the shell 35 is detachably connected to the liner 51. In this embodiment, the shell 35 and the liner 51 are detachably connected by the upper shell 351 and the top wall of the liner 51, so that the package structure 30 can be used in different compartments, achieving the modular effect of the package structure 30 and reducing the manufacturing cost. The package structure 30 also includes a heat preservation member 37 that is limitedly matched with the shell 35 to prevent heat from being transferred to the compartment when defrosting in the evaporation chamber 31.

[0050] Continue with reference Figure 1 and Figure 2 As shown, further, the box body also includes a partition assembly 52 detachably connected to the inner liner 51. In this embodiment, the packaging structure 30 and the partition assembly 52 are both detachably connected to the inner liner 51, so that the packaging structure 30 and the partition assembly 52 can be assembled with other inner liners, thereby realizing the modularization of the packaging structure 30 and the partition assembly 52 and reducing the manufacturing cost.

[0051] Specifically, the partition assembly 52 divides the storage space into an ice-making compartment 531 and a refrigeration compartment 532, and the housing 35 is exposed in the ice-making compartment 531. In this embodiment, the partition assembly 52 is used to divide the storage space, so that the ice-making compartment 531 and the refrigeration compartment 532 share a common liner 51, and the ice-making compartment 531 uses the packaging structure 30 for independent cooling. The refrigerator also includes an ice maker 70 and an ice storage box 80 arranged in the ice-making compartment 531.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each implementation mode may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
