[0004] However, the front side, rear side or both sides of the refrigerator usually need to reserve space as air supply duct and return air passage, which cannot be utilized, greatly compressing the product use space in the refrigerator cabinet. SUMMARY

This not only enables independent air supply on both sides, ensuring uniform and efficient cooling on both sides, but also allows the use of the space on one side of the first side wall 21 and the space on one side of the second side wall 22 as air supply channels, thus avoiding the need to separately set up the air duct 401 structure on the first side wall 21, the second side wall 22, or the back space, which would occupy the usable space inside the refrigerator.

[0086] Furthermore, such as Figure 2 As shown, the bottom of the air duct 401 is provided with an air intake 404. When the airflow is delivered downward along the first side wall 21 and the second side wall 22 to the cooling chamber 101, under the operation of the fan 6, the airflow in the cooling chamber 101 can flow back to the top and enter the air duct 401 through the air intake 404 to continue cooling, and then continue to be delivered along the first side wall 21 and the second side wall 22.

[0087] In current refrigerators, the air supply and return ducts typically occupy space on the front, back, or sides, making it unusable for storing items and thus reducing the actual usable space inside the refrigerator. The refrigeration device in this application, by arranging the air duct 401 laterally on the top of the inner liner 2 and utilizing the space between the first side wall 21 and the second side wall 22, makes the air duct 401 structure more compact. It eliminates the need for air supply or return ducts on the sides and back of the refrigeration compartment 101, maximizing the use of space inside the refrigeration compartment 101. This provides users with a more spacious, convenient, and energy-efficient storage space, meeting the diverse needs of modern families for refrigerator products.

[0088] It is particularly noteworthy that by integrating the first evaporator 51 and the second evaporator 52 into the same evaporator 5, the integrated arrangement of the first evaporator 51 and the second evaporator 52 simplifies the connection structure of the evaporator 5 and other components of the refrigeration system, avoiding the complex connection pipes and additional space required by dual independent evaporators. This makes the layout of the evaporator 5 in the refrigerator more compact, optimizes the space utilization of the refrigerator, and leaves more space for the air duct 401 or other components, thereby making the internal structure of the refrigeration device more compact.

[0089] like Figure 3 As shown, in some embodiments, the evaporator 5 may include a first evaporation tube 511. The first evaporation tube 511 may be disposed within the air duct 401. The first evaporation tube 511 may be arranged laterally within the air duct 401.

[0090] like Figure 3 As shown, in some embodiments, the evaporator 5 may include a second evaporation tube 521. The second evaporation tube 521 may be disposed within the air duct 401. The second evaporation tube 521 may be arranged laterally within the air duct 401.

[0091] like Figure 3 As shown, in some embodiments, the first evaporator 511 and the second evaporator 521 can be respectively disposed on opposite sides of the fan 6. One end of the first evaporator 511 can be connected to one end of the second evaporator 521, forming a continuous cooling path. The first evaporator 511 and the second evaporator 521 are distributed on opposite sides of the fan 6. The first evaporator 511 and the second evaporator 521 can respectively cool the airflow flowing towards the first sidewall 21 and the airflow towards the second sidewall 22.

[0092] like Figure 3 As shown, in some embodiments, the evaporator 5 may include a third evaporator tube 522 and a fourth evaporator tube 512. The third evaporator tube 522 may be disposed within the air duct 401. The third evaporator tube 522 and the second evaporator tube 521 may be arranged vertically spaced apart. One end of the third evaporator tube 522 may be connected to the end of the second evaporator tube 521 away from the first evaporator tube 511. The fourth evaporator tube 512 may be disposed within the air duct 401; the fourth evaporator tube 512 and the first evaporator tube 511 are arranged vertically spaced apart, and one end of the fourth evaporator tube 512 is connected to the end of the third evaporator tube 522 away from the second evaporator tube 521. The first evaporator tube 511 and the fourth evaporator tube 512 may form a first evaporation section 51. The second evaporator tube 521 and the third evaporator tube 522 may form a second evaporation section 52.

[0093] Specifically, the first evaporation pipe 511 and the fourth evaporation pipe 512 are configured as the first evaporation part 51, and the second evaporation pipe 521 and the third evaporation pipe 522 are configured as the second evaporation part 52. The first evaporation pipe 511 and the fourth evaporation pipe 512, and the second evaporation pipe 521 and the third evaporation pipe 522 are arranged in an up-down interval. In this way, the first evaporation part 51 and the second evaporation part 52 are arranged in a double-layer heat exchange structure in an up-down manner, which not only increases the heat exchange area and further improves the heat exchange efficiency when the air flows through the evaporation pipe, but also reasonably utilizes the vertical space in the air duct 401. On the other hand, the first evaporation pipe 511, the second evaporation pipe 521, the third evaporation pipe 522 and the fourth evaporation pipe 512 are sequentially connected, so that the refrigerant can flow into the first evaporation part 51 and then flow out of the first evaporation part 51, or the refrigerant can flow into the second evaporation part 52 and then flow out of the second evaporation part 52, which is conducive to the centralized distribution of the evaporation pipe of the evaporator 5, and makes the structure of the evaporator 5 more compact.

[0094] Further, since the refrigerator extracts the air in the refrigeration compartment 101 from the middle position through the air inlet 404 at the bottom of the air duct 401, and then cools the air through the evaporator 5 and sends the cooled air to the two sides of the refrigeration compartment 101 from the two ends (i.e. the first air outlet 402 and the second air outlet 403) of the air duct 401, the cold air is uniformly distributed in the refrigeration compartment 101, thereby reducing the local overcooling condition, and the frosting amount of a single evaporator 5 is correspondingly reduced. Moreover, since the cold air is distributed from the middle to the two sides, compared with the traditional single-side air supply design, the air volume blown to each side of the refrigeration compartment 101 is relatively reduced. At the same time, since the cold air exchanges heat with the evaporator 5 in the air duct 401, part of the moisture is removed, so the moisture content in the sent cold air is correspondingly reduced, and the cold air is more uniformly distributed, reducing the local overcooling condition, so that the frosting amount of a single evaporator 5 is correspondingly reduced in the same time.

[0095] Figure 6 For Figure 1 the installation schematic view of the evaporator; Figure 7 For Figure 6 the perspective view of the evaporator; Figure 8 For Figure 6 the exploded view of the evaporator.

[0096] As Figure 2 and Figure 6 shown, in some embodiments, the evaporator 5 can include a first inlet and outlet pipe 53. The first inlet and outlet pipe 53 can be connected to one end of the first evaporation pipe 511 away from the second evaporation pipe 521. The first inlet and outlet pipe 53 can be used for the refrigerant to flow into the first evaporation part 51 and the second evaporation part 52. The end of the first inlet and outlet pipe 53 away from the first evaporation pipe 511 can extend outside the air duct 401 and be arranged downwardly.

[0097] As Figure 2and Figure 6 As shown, in some embodiments, the first inlet / outlet pipe 53 may be connected to the condenser, so that the refrigerant flows through the first inlet / outlet pipe 53 into the first evaporator 51 and the second evaporator 52. The first inlet / outlet pipe 53 may extend outside the air duct 401 and downward into the compressor compartment at the bottom.

[0098] like Figure 2 and Figure 6 As shown, in some embodiments, the evaporator 5 may include a second inlet / outlet pipe 54. The second inlet / outlet pipe 54 may be connected to the end of the fourth evaporator pipe 512 away from the third evaporator pipe 522. The second inlet / outlet pipe 54 is used to allow refrigerant to flow out of the first evaporator section 51 and the second evaporator section 52. The end of the second inlet / outlet pipe 54 away from the fourth evaporator pipe 512 may extend outside the air duct 401 and extend downward.

[0099] In some embodiments, the second inlet / outlet pipe 54 may be connected to the compressor, such that refrigerant flows through the second inlet / outlet pipe 54 from the first evaporator 51 and the second evaporator 52 into the compressor. The second inlet / outlet pipe 54 may extend outside the air duct 401 and downward into the compressor compartment at the bottom.

[0100] like Figure 7 As shown, in some embodiments, the first inlet / outlet pipe 53 and the second inlet / outlet pipe 54 are distributed on the same side of the first evaporation section 51, and the first inlet / outlet pipe 53 and the second inlet / outlet pipe 54 are arranged adjacent to each other at intervals and extend downward along the same side of the liner 2.

[0101] Since the first inlet / outlet pipe 53 and the second inlet / outlet pipe 54 need to extend from the compressor compartment at the bottom to the air duct 401 at the top, the first inlet / outlet pipe 53 and the second inlet / outlet pipe 54 are both distributed on the same side of the evaporator and are arranged adjacent to each other. This makes the total refrigerant piping around the refrigerator more compact, and at the same time avoids reserving installation space for the first inlet / outlet pipe 53 and the second inlet / outlet pipe 54 in many places inside the air duct 401 and the refrigerator, thereby improving the usable space inside the refrigerator.

[0102] like Figure 6 and Figure 7 As shown, in some embodiments, the first inlet / outlet pipe 53 and the second inlet / outlet pipe 54 may be evenly distributed at the corner of the first evaporation section 51 near the rear end of the first sidewall 21.

[0103] It should be noted that in some other embodiments, one end of the first inlet / outlet pipe 53 and the second inlet / outlet pipe 54 may be connected to the second evaporation section 52, respectively. The first inlet / outlet pipe 53 and the second inlet / outlet pipe 54 may be evenly distributed at the corners of the second evaporation section 52 near the rear end of the second sidewall 22.

[0104] like Figure 2 and Figure 8As shown in FIG. 1, in some embodiments, the evaporator 5 can include a first communication pipe 55. The first communication pipe 55 can be arranged in the transverse direction in the air duct 401. One end of the first communication pipe 55 can be connected to the first evaporation pipe 511. The other end of the first communication pipe 55 can be connected to the second evaporation pipe 521. The first communication pipe 55 communicates the first evaporation portion 51 and the second evaporation portion 52, and the first communication pipe 55 is arranged in the transverse direction in the air duct 401, so that the refrigerant can flow smoothly between the first evaporation portion 51 and the second evaporation portion 52.

[0105] As shown in FIG. 1, in some embodiments, the evaporator 5 can include a first communication pipe 55. The first communication pipe 55 can be arranged in the transverse direction in the air duct 401. One end of the first communication pipe 55 can be connected to the first evaporation pipe 511. The other end of the first communication pipe 55 can be connected to the second evaporation pipe 521. The first communication pipe 55 communicates the first evaporation portion 51 and the second evaporation portion 52, and the first communication pipe 55 is arranged in the transverse direction in the air duct 401, so that the refrigerant can flow smoothly between the first evaporation portion 51 and the second evaporation portion 52. Figure 2 Figure 8 As shown in FIG. 1, in some embodiments, the evaporator 5 can include a second communication pipe 56. The second communication pipe 56 can be arranged in the transverse direction in the air duct 401. One end of the second communication pipe 56 can be connected to the third evaporation pipe 522. The other end of the second communication pipe 56 can be connected to the fourth evaporation pipe 512. The second communication pipe 56 communicates the first evaporation portion 51 and the second evaporation portion 52, and the second communication pipe 56 is arranged in the transverse direction in the air duct 401, so that the refrigerant can flow smoothly between the first evaporation portion 51 and the second evaporation portion 52.

[0106] The first evaporation pipe 511, the second evaporation pipe 521, the third evaporation pipe 522, and the fourth evaporation pipe 512 are sequentially connected by the first communication pipe 55 and the second communication pipe 56 arranged between the first evaporation portion 51 and the second evaporation portion 52, and the first communication pipe 55 and the second communication pipe 56 are arranged in the transverse direction of the air duct 401, so that the first evaporation portion 51 and the second evaporation portion 52 can be arranged at intervals and communicated by the first communication pipe 55 and the second communication pipe 56, and the space formed between the first evaporation portion 51 and the second evaporation portion 52 can be used to install the fan 6.

[0107] As shown in FIG. 1, in some embodiments, the first communication pipe 55 and the second communication pipe 56 can be arranged on the same side. The first communication pipe 55 and the second communication pipe 56 can be arranged at intervals in the vertical direction. In this way, by arranging the first communication pipe 55 and the second communication pipe 56 on the same side, the structure of the evaporator 5 in the air duct 401 can be more compact, thereby reserving more space for the installation of other components and optimizing the gas flow channel in the air duct 401. Figure 8 As shown in FIG. 1, in some embodiments, the evaporator 5 can include a first mounting plate 57. The first mounting plate 57 can be arranged in the transverse direction in the air duct 401. The first evaporation portion 51 can be mounted on the first mounting plate 57. The second evaporation portion 52 can be mounted on the first mounting plate 57.

[0108] Figure 7 As shown in FIG. 1, in some embodiments, the evaporator 5 can include a first mounting plate 57. The first mounting plate 57 can be arranged in the transverse direction in the air duct 401. The first evaporation portion 51 can be mounted on the first mounting plate 57. The second evaporation portion 52 can be mounted on the first mounting plate 57. Figure 8 As shown in FIG. 1, in some embodiments, the evaporator 5 can include a first mounting plate 57. The first mounting plate 57 can be arranged in the transverse direction in the air duct 401. The first evaporation portion 51 can be mounted on the first mounting plate 57. The second evaporation portion 52 can be mounted on the first mounting plate 57.

[0109] Figure 7 As shown in FIG. 1, in some embodiments, the evaporator 5 can include a first mounting plate 57. The first mounting plate 57 can be arranged in the transverse direction in the air duct 401. The first evaporation portion 51 can be mounted on the first mounting plate 57. The second evaporation portion 52 can be mounted on the first mounting plate 57.​​​Figure 8 As shown in some embodiments, the evaporator 5 can include a second mounting plate 58. The second mounting plate 58 can be arranged transversely in the air duct 401. The first evaporation portion 51 can be mounted on the second mounting plate 58. The second evaporation portion 52 can be mounted on the second mounting plate 58.

[0110] As shown in some embodiments, the second mounting plate 58 can be spaced apart from the rear side of the first mounting plate 57. The first evaporation portion 51 can be arranged between one end of the first mounting plate 57 and one end of the second mounting plate 58. The front end of the first evaporation portion 51 can be fixed on the first mounting plate 57, and the rear end of the first evaporation portion 51 can be fixed on the second mounting plate 58. Figure 6 Figure 7 As shown in some embodiments, the second mounting plate 58 can be spaced apart from the rear side of the first mounting plate 57. The first evaporation portion 51 can be arranged between one end of the first mounting plate 57 and one end of the second mounting plate 58. The front end of the first evaporation portion 51 can be fixed on the first mounting plate 57, and the rear end of the first evaporation portion 51 can be fixed on the second mounting plate 58.

[0111] The second evaporation portion 52 can be arranged between the other end of the first mounting plate 57 and the other end of the second mounting plate 58. The front end of the second evaporation portion 52 can be fixed on the first mounting plate 57. The rear end of the second evaporation portion 52 can be fixed on the second mounting plate 58. Wherein, the first evaporation portion 51, the second evaporation portion 52, the first mounting plate 57 and the second mounting plate 58 form a first mounting area 407, and the fan 6 is arranged in the first mounting area 407.

[0112] Specifically, by arranging the first mounting plate 57 and the second mounting plate 58, the front and rear ends of the first evaporation portion 51 are fixed and supported between the first mounting plate 57 and the second mounting plate 58, and the front and rear ends of the second evaporation portion 52 are also fixed and supported between the first mounting plate 57 and the second mounting plate 58, thereby providing a stable support structure for the first evaporation portion 51 and the second evaporation portion 52, and enhancing the overall rigidity and strength of the evaporator 5.

[0113] On the other hand, since the fan 6 is installed in the first mounting area 407 formed by the first evaporation portion 51, the second evaporation portion 52, the first mounting plate 57 and the second mounting plate 58, the air duct 401 structure can be defined between the first mounting plate 57 and the second mounting plate 58. The fixing and support of the first mounting plate 57 and the second mounting plate 58 not only further enhances the structural strength of the air duct 401, improves the stability and reliability of the air duct 401 structure, but also helps to reduce the turbulence and vortex of the airflow in the air duct 401, and improves the smoothness and uniformity of the airflow, thereby further improving the refrigeration efficiency.

[0114] As shown in some embodiments, the second mounting plate 58 can be spaced apart from the rear side of the first mounting plate 57. The first evaporation portion 51 can be arranged between one end of the first mounting plate 57 and one end of the second mounting plate 58. The front end of the first evaporation portion 51 can be fixed on the first mounting plate 57, and the rear end of the first evaporation portion 51 can be fixed on the second mounting plate 58. Figure 8 ​As shown in some embodiments, the first communication pipe 55 and the second communication pipe 56 can be arranged on the side of the first mounting plate 57 away from the fan 6, or the first communication pipe 55 and the second communication pipe 56 can be arranged on the side of the second mounting plate 58 away from the fan 6, so as to avoid interference between the fan 6 and the first communication pipe 55 and the second communication pipe 56.

[0115] As shown in some embodiments, the first evaporation part 51 can be provided with a plurality of first heat dissipation fins 513. The first heat dissipation fins 513 can be arranged in parallel between the first mounting plate 57 and the second mounting plate 58. The plurality of first heat dissipation fins 513 can be arranged in parallel. The first evaporation pipe 511 and the fourth evaporation pipe 512 can be arranged between the plurality of heat dissipation fins in the direction of arranging in front of and behind the plurality of first heat dissipation fins 513. Figure 7

[0116] Among them, by arranging a plurality of first heat dissipation fins 513 on the first evaporation part 51, and arranging the plurality of first heat dissipation fins 513 in parallel, the heat dissipation area of the first evaporation part 51 is increased, which is conducive to faster heat transfer from the first evaporation part 51 to the air, thereby improving the refrigeration efficiency. Moreover, the plurality of first heat dissipation fins 513 arranged in parallel can also optimize the airflow path, so that the airflow on the side of the fan 6 can flow smoothly along the gap between the plurality of first heat dissipation fins 513 to the side of the first side wall 21.

[0117] As shown in some embodiments, the first evaporation part 51 can be provided with a plurality of second heat dissipation fins 523. The second heat dissipation fins 523 can be arranged in parallel between the first mounting plate 57 and the second mounting plate 58. The plurality of second heat dissipation fins 523 can be arranged in parallel. The second evaporation pipe 521 and the fourth evaporation pipe 512 can be arranged between the plurality of heat dissipation fins in the direction of arranging in front of and behind the plurality of second heat dissipation fins 523. Figure 7 Among them, by arranging a plurality of second heat dissipation fins 523 on the second evaporation part 52, and arranging the plurality of second heat dissipation fins 523 in parallel, the heat dissipation area of the second evaporation part 52 is increased, which is conducive to faster heat transfer from the second evaporation part 52 to the air, thereby improving the refrigeration efficiency. Moreover, the plurality of second heat dissipation fins 523 arranged in parallel can also optimize the airflow path, so that the airflow on the side of the fan 6 can flow smoothly along the gap between the plurality of second heat dissipation fins 523 to the side of the second side wall 22.

[0118] In some embodiments, the refrigerator can include a duct cover plate 4. The duct cover plate 4 can be arranged transversely on the top of the box body 2. The duct cover plate 4 and the top of the box body 2 can form a duct 401.

[0119] As shown in some embodiments, the first evaporation part 51 can be provided with a plurality of first heat dissipation fins 513. The first heat dissipation fins 513 can be arranged in parallel between the first mounting plate 57 and the second mounting plate 58. The plurality of first heat dissipation fins 513 can be arranged in parallel. The first evaporation pipe 511 and the fourth evaporation pipe 512 can be arranged between the plurality of heat dissipation fins in the direction of arranging in front of and behind the plurality of first heat dissipation fins 513.

[0120] Figure 6 ​​and Figure 7 As shown in FIG. 1, in some embodiments, the first evaporation part 51, the second evaporation part 52 and the fan 6 can be arranged on the air duct cover plate 4. In the front-to-back direction of the air duct cover plate 4, the bottom wall of the air duct cover plate 4 can be arranged in a downwardly inclined manner. The rear end of the air duct cover plate 4 can be provided with a drain hole 406. Since the air in the air duct 401 flows through the first evaporation part 51 and the second evaporation part 52, the moisture in the air is likely to condense into liquid, and by arranging the bottom wall of the air duct cover plate 4 in a downwardly inclined manner in the front-to-back direction and providing the rear end of the air duct cover plate 4 with the drain hole 406, the condensed water can be easily drained, avoiding the problem of bacterial breeding and odor caused by water accumulation. Therefore, by configuring the air duct cover plate 4 in an inclined manner and defining the air duct 401 with the top of the box body 2, the structure of the air duct 401 in the refrigerator can be further optimized, the drainage performance can be enhanced, and the space utilization can be improved, etc.

[0121] As shown in FIG. 1, in some embodiments, the box body 2 can include a third side wall 23. The third side wall 23 can be arranged at the back of the refrigeration compartment 101. The third side wall 23 can be arranged between the rear side of the first side wall 21 and the second side wall 22. Figure 2 In some embodiments, the drain hole 406 can be arranged at the position where the air duct cover plate 4 is located at the intersection of the rear end of the first side wall 21 and the third side wall 23. Alternatively, the drain hole 406 can be arranged at the position where the air duct cover plate 4 is located at the intersection of the rear end of the second side wall 22 and the third side wall 23.

[0122] In other embodiments, the drain hole 406 can be arranged on the side of the air duct cover plate 4 close to the third side wall 23.

[0123] In some embodiments, the refrigerator can include a drain pipe 7. The drain pipe 7 can be arranged on one side of the box body 2 in a vertical manner. The upper end of the drain pipe 7 can be connected to the drain hole 406. The lower end of the drain pipe 7 can be arranged in a downwardly extending manner. By arranging the drain pipe 7, the condensed water in the air duct cover plate 4 can be smoothly drained from the air duct cover plate 4 and directly flow to the bottom of the refrigerator or a designated drainage area through the drain pipe 7, avoiding the problem of water accumulation inside the air duct 401 or the refrigeration compartment 101 and bacterial breeding.

[0124] As shown in FIG. 1, in some embodiments, the front wall of the third side wall 23 can be concavely provided with a second mounting area 201. The drain pipe 7, the first access pipe 53 and the second access pipe 54 can be respectively arranged in the second mounting area 201 and extend downwardly along the third side wall 23.

[0125] Figure 9 and Figure 10 As shown in FIG. 1, in some embodiments, the front wall of the third side wall 23 can be concavely provided with a second mounting area 201. The drain pipe 7, the first access pipe 53 and the second access pipe 54 can be respectively arranged in the second mounting area 201 and extend downwardly along the third side wall 23.

[0126] ​The second mounting area 201 is concavely arranged on the front wall of the third side wall 23, thereby providing the first access pipe 53, the second access pipe 54 and the drain pipe 7 with special mounting spaces. Moreover, the first access pipe 53, the second access pipe 54 and the drain pipe 7 are arranged in the second mounting area 201 of the third side wall 23 and extend downward along the second mounting area 201, which not only maximizes the space utilization and optimizes the space utilization, but also avoids the first access pipe 53, the second access pipe 54 and the drain pipe 7 occupying the space of the refrigeration compartment 101 inside the refrigerator, and avoids the first access pipe 53, the second access pipe 54 and the drain pipe 7 being randomly hung or protruding in the cabinet 1, thereby optimizing the space utilization and making the appearance of the refrigeration device more tidy.

[0127] Figure 11 FIG. 4 is a partial view of the refrigerator according to an embodiment of the present disclosure; Figure 1 FIG. 5 is a partial view of the refrigerator according to an embodiment of the present disclosure; Figure 12 FIG. 6 is an enlarged view of D in FIG. 5. It should be noted that, in order to conveniently show the internal structure of the refrigerator, Figure 11 FIG. 7 is a partial view of the refrigerator according to an embodiment of the present disclosure; Figure 11 FIG. 8 is a partial view of the refrigerator according to an embodiment of the present disclosure;

[0128] As shown in FIGS. 5 and 6, in some embodiments, the cabinet 2 can include a decorative plate. The decorative plate can be arranged at the front side opening of the second mounting area 201. In this way, the first access pipe 53, the second access pipe 54 and the drain pipe 7 can be mounted on the second mounting area 201 at the back of the decorative plate, and the decorative plate can effectively shield the pipes in the second mounting area 201, so that the appearance of the interior of the refrigerator is more tidy and beautiful, and the visual experience of the user is improved. Figure 11 Figure 12 As shown in FIGS. 7 and 8, in some embodiments, the drain pipe 7 can be connected to the back side of the decorative plate 10.

[0129] As shown in FIGS. 7 and 8, in some embodiments, the drain pipe 7 can be connected to the back side of the decorative plate 10. Figure 11 Figure 12 As shown in FIGS. 7 and 8, in some embodiments, the bottom wall of the air duct cover plate 4 towards the top of the cabinet 2 can be provided with a protruding edge 41. The protruding edge 41 and the bottom wall of the air duct cover plate 4 can be enclosed to form a water collecting groove 405. The water collecting groove 405 can be in communication with the drain hole 406.

[0130] As shown in FIGS. 7 and 8, in some embodiments, the drain pipe 7 can be connected to the back side of the decorative plate 10.

[0131] As shown in FIGS. 7 and 8, in some embodiments, the drain pipe 7 can be connected to the back side of the decorative plate 10. Figure 8

[0132] ​​​Specifically, by protrudingly arranging the protruding edge 41 on the bottom wall of the air duct cover plate 4 towards the top of the box body 2, a water collecting groove 405 can be formed on the air duct cover plate 4, when the condensed water is formed on the bottom wall of the air duct cover plate 4 and flows, the protruding edge 41 can guide the condensed water to flow into the water collecting groove 405, so as to effectively collect the condensed water, and the water collecting groove 405 is communicated with the liquid discharge hole 406, so that the collected condensed water can be discharged in time, avoiding the accumulation of condensed water on the air duct cover plate 4 or the top of the box body 2.

[0133] As shown in Figure 8 , in some embodiments, the protruding edge 41 can be protrudingly arranged around the edge of the air duct cover plate 4.

[0134] Figure 13 For Figure 6 , the connection diagram of the fixing frame and the air duct cover plate is shown; Figure 14 For Figure 13 , the schematic diagram of the fixing frame is shown.

[0135] As shown in Figure 13 and Figure 14 , in some embodiments, the refrigerator can include a fixing frame 8. The fixing frame 8 can be arranged in space above the air inlet 404. The fan 6 can be arranged between the air inlet 404 and the fixing frame 8. The fixing frame 8 can be used to support the fan 6 in the air duct 401. By arranging the fixing frame 8 in the air duct 401, the fixing frame 8 as an additional support structure can connect the fan 6 to the fixing frame 8, preventing the fan 6 or other components from being displaced or damaged due to vibration or external force.
