[0082] like Figure 2 As shown, in some embodiments, the refrigerator may include a box liner 2. The box liner 2 may be arranged in the box body 1. A refrigeration compartment 101 may be arranged in the box liner 2.

[0083] like Figure 2 and Figure 3 As shown, in some embodiments, the refrigeration compartment 101 may have a first side wall 21 and a second side wall 22 that are disposed laterally opposite to each other. The first side wall 21 and the second side wall 22 may be disposed on the left and right sides of the refrigeration compartment 101, or the first side wall 21 and the second side wall 22 may be disposed on the front and back sides of the refrigeration compartment 101.

[0084] In some embodiments, the multiple refrigeration compartments 101 can be used as independent storage spaces, such as a freezer, a refrigerator, and a temperature-changing chamber, etc., to meet different refrigeration requirements such as freezing, refrigeration, and temperature-changing according to different types of food, and store items that need to be refrigerated or frozen. The multiple refrigeration compartments 101 can be arranged in upper and lower partitions, or in left and right partitions.

[0085] like Figure 1 As shown, in some embodiments, the refrigerator may include a door body 3. The door body 3 may be hinged to the front side of the cabinet 11 to open and close the refrigeration compartment 101.

[0086] It should be noted that a plurality of door bodies 3 can be provided. The door bodies 3 can be provided one by one with the refrigeration compartments 101. Multiple door bodies 3 can open and close one refrigeration compartment 101 at the same time. One door body 3 can also open and close multiple refrigeration compartments 101 at the same time.

[0087] In some embodiments, the refrigerator may include a refrigeration system. The refrigeration system may be disposed inside the box body 11. The refrigeration system may be used to provide cold air inside the refrigerator to maintain a low temperature environment in each refrigeration compartment 101.

[0088] In some embodiments, the refrigeration system may include a compressor (not shown). The compressor may serve as a power source for the refrigeration cycle, sucking in low-temperature, low-pressure refrigerant gas and compressing it into high-temperature, high-pressure gas. The compressor may deliver high-temperature, high-pressure refrigerant to the condenser.

[0089] In some embodiments, the refrigeration system may include a condenser (not shown). The condenser may be used to receive the refrigerant flowing out of the compressor, and may cool the high-temperature and high-pressure refrigerant gas from the compressor and convert it into a liquid state. The condenser may transfer the heat in the refrigerant to the surrounding air, thereby lowering the temperature of the refrigerant.

[0090] In some embodiments, the refrigeration system may include a throttling device (not shown). The condenser may deliver the condensed refrigerant to the throttling device. The throttling device may be a capillary tube. The throttling device may be used to throttle and reduce the pressure of the refrigerant.

[0091] In some embodiments, the refrigeration system may include a first evaporation part 51. The throttling device may deliver the throttled and depressurized refrigerant to the first evaporator 5. The first evaporation part 51 may be used for evaporation and boiling of the refrigerant vapor to absorb the heat of the surrounding medium.

[0092] In some embodiments, the refrigeration system may include a second evaporation part 52. The throttling device may deliver the throttled and depressurized refrigerant to the second evaporator 5. The second evaporation part 52 may be used for evaporation and boiling of the refrigerant vapor to absorb the heat of the surrounding medium.

[0093] In some embodiments, the compressor, the condenser, the throttling device, the first evaporation part 51 and the second evaporation part 52 may be sequentially connected to form a refrigeration circuit. The refrigerant may circulate in the refrigeration circuit to achieve refrigeration of the interior of the box 1.

[0094] like Figure 2 As shown, in some embodiments, the refrigerator may include an air duct 401. The evaporator 5 may be disposed in the air duct 401. The air duct 401 may be connected to the refrigeration compartment 101 to transport the cold air formed by flowing through the first evaporation part 51 and the second evaporation part 52 to the refrigeration compartment 101, thereby realizing the low-temperature storage function in the refrigeration compartment 101.

[0095] like Figure 2 and Figure 3 As shown, in some embodiments, the air duct 401 can be arranged horizontally on the top of the box 2. The first side wall 21 and the second side wall 22 can be arranged on both sides of the air duct 401. A first air outlet 402 can be provided at one end of the air duct 401 close to the first side wall 21. The first evaporation portion 51 can be arranged on one side of the air duct 401 close to the first side wall 21. The first air outlet 402 can be connected to the refrigeration compartment 101, and the cold air formed by the air flowing through the first evaporation portion 51 can be transported to the refrigeration compartment 101 through the first air outlet 402.

[0096] like Figure 2 As shown, in some embodiments, a second air outlet 403 may be provided at one end of the air duct 401 close to the second side wall 22. The second evaporation portion 52 may be provided at one side of the air duct 401 close to the second side wall 22. The second air outlet 403 may be communicated with the refrigeration compartment 101, and the cold air formed by the air flowing through the second evaporation portion 52 may be transported to the refrigeration compartment 101 through the second air outlet 403.

[0097] like Figure 2 As shown, in some embodiments, the refrigerator may include a fan 6. The fan 6 may be disposed at the air inlet. The fan 6 may be located between the first evaporation portion 51 and the second evaporation portion 52. An air suction port 404 may be disposed at the bottom of the air duct 401. The air suction port 404 may be in communication with the refrigeration compartment 101.

[0098] The fan 6 can be configured as follows: when the fan 6 is started, the fan 6 can draw air from the air inlet 404 into the air duct 401 to form an airflow; part of the airflow flows to the refrigeration compartment 101 through the first evaporation portion 51 and the first air outlet 402, and supplies air to the refrigeration compartment 101 along one side of the first side wall 21; another part of the airflow flows to the refrigeration compartment 101 through the second evaporation portion 52 and the second air outlet 403, and supplies air to the refrigeration compartment 101 along one side of the second side wall 22.

[0099] Specifically, in the refrigerator disclosed in the present application, the air duct 401 is arranged at the top of the box 2, wherein the air duct 401 is respectively provided with a first air outlet 402 and a second air outlet 403 on two oppositely arranged first side walls 21 and second side walls 22 facing the refrigeration compartment 101, and an air suction port 404 is provided at the bottom of the air duct 401. When the fan 6 is working, the air in the refrigeration compartment 101 can be sucked into the air duct 401 under the action of the fan 6 to form an airflow, wherein the airflow is cooled by the first evaporation part 51 and the second evaporation part 52 in the air duct 401, and then flows out from the first air outlet 402 and the second air outlet 403 respectively, and is transported downward along the two side walls to supply air to the refrigeration compartment 101. This not only realizes independent air supply on both sides to ensure the uniformity and efficiency of cooling on both sides, but also can utilize the space on the first side wall 21 and the space on the second side wall 22 as air supply channels, thereby avoiding the need to separately set up an air duct 401 structure on the first side wall 21, the second side wall 22 or the back space to occupy the usable space inside the refrigerator.

[0100] Furthermore, an air suction port 404 is provided at the bottom of the air duct 401. After the airflow is respectively transported downward to the refrigeration chamber 101 along the first side wall 21 and the second side wall 22, under the operation of the fan 6, the airflow in the refrigeration chamber 101 can flow back to the top and enter the air duct 401 through the air suction port 404 to continue cooling and then continue to be transported along the first side wall 21 and the second side wall 22.

[0101] In current refrigerators, the air supply duct and the return air duct usually occupy the space on the front, back or both sides of the refrigerator, and these spaces cannot be used to store items, thereby compressing the actual usable space in the refrigerator. The refrigeration device in the present application arranges the air duct 401 horizontally on the top of the box 2 and utilizes the space between the first side wall 21 and the second side wall 22, so that the air duct 401 structure of the refrigeration device is more compact, and there is no need to set the air supply duct 401 or the return air duct 301 on the side and back space of the refrigeration compartment 101. The space inside the refrigeration compartment 101 is maximized, and a more spacious, convenient and energy-saving storage space is provided for users, meeting the diversified needs of modern families for refrigerator products.

[0102] Figure 4 for Figure 1 Sectional view 2; Figure 5 for Figure 1 Internal schematic diagram of Figure 6 for Figure 1 Internal schematic diagram from another perspective; Figure 7 for Figure 2 A partial enlarged view of point B; Figure 8 for Figure 2 A partial enlarged view of point C; Fig. 9for Figure 1 Sectional view three.

[0103] like Figure 4 and Figure 5 As shown, in some embodiments, the refrigerator may include a shelf 7. The shelf 7 may be arranged transversely in the refrigeration compartment 101. The transversely arranged top surface of the shelf 7 may be used to support items to be refrigerated.

[0104] like Figure 2 and Figure 8 As shown, in some embodiments, one side of the shelf 7 may be connected to the first side wall 21. The shelf 7 may be spaced apart from the first side wall 21 to form a first gap 701. The other side of the shelf 7 is connected to the second side wall 22, and the shelf 7 and the second side wall 22 are spaced apart to form a second gap 702.

[0105] It should be noted that the two sides of the shelf 7 are connected to the first side wall 21 and the second side wall 22. For example, the first side wall 21 and the second side wall 22 may be provided with shelf support columns 9, respectively, and the shelf support columns 9 are provided with supporting snap-in positions or hooks, and the two sides of the shelf 7 may be supported on the snap-in positions or connected to the first side wall 21 and the second side wall 22 respectively through hooks. Thus, the first gap 701 and the second gap 702 are formed between the two sides of the shelf 7 and the first side wall 21 and the second side wall 22, respectively.

[0106] In this way, when the fan 6 is started, Figure 2 and Fig. 9 As shown, when the airflow enters the refrigeration compartment 101 through the first air outlet 402 and is transported downward along the first side wall 21 to reach the shelf 7, part of the airflow can reach the top support space of the shelf 7, while the other part of the airflow can continue to be transported downward along the first gap 701. Similarly, when the airflow enters the refrigeration compartment 101 through the second air outlet 403 and is transported downward along the second side wall 22 to reach the shelf 7, part of the airflow can reach the top support space of the shelf 7, while the other part of the airflow can continue to be transported downward along the second gap 702. By using the first gap 701 and the second gap 702 formed between the two sides of the shelf 7 and the first side wall 21 and the second side wall 22 as air supply channels, the gaps between the two sides of the shelf 7 and the box 2 can be fully utilized, simplifying the overall structure of the refrigerator, making the space inside the refrigerator more spacious, and convenient for users to store items.

[0107] like Figure 5 and Figure 6As shown, in some embodiments, a plurality of shelves 7 may be provided. The plurality of shelves 7 may be arranged in the refrigeration compartment 101 at intervals along the vertical direction. The opposite sides of the plurality of shelves 7 may respectively form a first gap 701 with the first side wall 21, and a second gap 702 with the second side wall 22. After a part of the airflow flows to the refrigeration compartment 101 through the first air outlet 402, it can be sequentially transported downward along the plurality of first gaps 701. After another part of the airflow flows to the refrigeration compartment 101 through the second air outlet 403, it can be sequentially transported downward along the plurality of second gaps 702.

[0108] Specifically, a space for accommodating items can be formed between adjacent shelves 7. When the fan 6 is started, part of the airflow enters the refrigeration chamber 101 through the first air outlet 402, and is sequentially transported downward along the first gap 701, while the other part of the airflow enters through the second air outlet 403, and is sequentially transported downward along the second gap 702. In this process, the airflow flowing along both sides can be sequentially transported to the storage space of the next shelf 7 through the first gap 701 and the second gap 702 of each layer, so that the airflow can be transported downward to the shelf 7 below. Compared with the prior art, the structure of the rear air supply duct 401 of the existing product is changed, and the depth direction of the shelf 7 can be directly extended to the back of the box 2, thereby increasing the product placement space and improving the product usage volume.

[0109] Fig.10 for Figure 1 Schematic diagram of the middle liner; Fig.11 for Figure 1 Schematic diagram of the middle liner from another perspective.

[0110] like Fig.10 As shown, in some embodiments, the first side wall 21 facing the cabinet 1 may be recessed to form a first recessed area 201. The first recessed area 201 may be arranged to extend downward from one end of the first side wall 21 close to the air duct 401. The top of the first recessed area 201 may be connected to the first air outlet 402. The first recessed area 201 may be used to form a flow channel for airflow along the first side wall 21, so as to guide the airflow to be transported downward along the first side wall 21 into the refrigeration compartment 101. Among them, the first gap 701 is formed in the first recessed area 201.

[0111] In order to further improve the space utilization and air supply efficiency of the refrigerator, the first side wall 21 is recessed toward one side of the box body 1 to form a first recessed area 201, and the first gap 701 is formed in the first recessed area 201, so that after the airflow flows out through the first air outlet 402, it can flow along the shape and direction of the first recessed area 201. The setting of the first recessed area 201 can guide the airflow, thereby guiding the cold air downward to various positions of the refrigeration chamber 101. Moreover, the first recessed area 201 can not only increase the channel space for the airflow to flow along the first side wall 21, thereby achieving a good conveying effect of guiding the airflow, but also avoid the problem of affecting the product use space due to the increase in the space of the flow channel.

[0112] like Fig.11 As shown, in some embodiments, the side of the second side wall 22 facing the cabinet 1 may be recessed to form a second recessed area 202. The second recessed area 202 may be arranged to extend downward from one end of the second side wall 22 close to the air duct 401. The top of the second recessed area 202 may be connected to the second air outlet 403. The second recessed area 202 may be used to form a flow channel for airflow along the second side wall 22, so as to guide the airflow to be transported downward along the second side wall 22 into the refrigeration compartment 101. Among them, the second gap 702 may be formed in the second recessed area 202.

[0113] In order to further improve the space utilization and air supply efficiency of the refrigerator, the second side wall 22 is recessed toward one side of the box body 1 to form a second recessed area 202, and the second gap 702 is formed in the second recessed area 202, so that after the airflow flows out through the second air outlet 403, it can flow along the shape and direction of the second recessed area 202. The setting of the second recessed area 202 can guide the airflow, thereby guiding the cold air downward to various positions of the refrigeration compartment 101. In addition, the second recessed area 202 can not only increase the channel space for the airflow to flow along the second side wall 22, thereby achieving a good conveying effect of guiding the airflow, but also avoid the problem of affecting the product use space due to the increase in the space of the flow channel.

[0114] like Figure 4 As shown, in some embodiments, the door body 3 and the front sides of the plurality of shelves 7 may be spaced apart to form a return air channel 301 . The top area of ​​the return air channel 301 is connected to the air suction port 404 .

[0115] Specifically, the return air channel 301 is formed by setting an interval between the door body 3 and the front sides of the plurality of shelves 7. When the fan 6 is started, the airflow generated by the top air duct 401 will be supplied along the first side wall 21 and the second side wall 22 respectively, and continue to be transported downward through the first gap 701 and the second gap 702 on both sides of each shelf 7, wherein part of the airflow will reach the shelf 7 of each layer and exchange heat with the products on the shelf 7, and then the airflow can flow back to the top air duct 401 through the return air channel 301 between the back side of the door body 3 and the shelf 7 to continue to form cold air and be transported to the refrigeration chamber 101 again.

[0116] In the above process, the airflow in the refrigeration room 101 can smoothly return to the air inlet 404 through the return air channel 301 and continue to enter the air duct 401, forming an efficient airflow circulation system. In this way, it is possible to avoid setting the return air channel 301 on the back or side of the box 2 to compress the product use space in the refrigeration room 101, and because the airflow is sent at high speed through the first side wall 21 and the second side wall 22, the wind speed and temperature of the airflow passing through the inner surface of the door body 3 can be reduced, thereby avoiding the problem of the wind in the refrigeration room 101 passing over the inner surface of the glass door at a high wind speed and quickly taking away the heat of the glass surface, causing the temperature of the glass door to be low and condensation of the glass door.

[0117] like Figure 4 As shown, in some embodiments, the air duct 401 can be arranged on the side of the top of the box 2 away from the door body 3. In this way, it can be avoided that the air duct 401 is arranged on the top front side of the box 2 to affect the appearance.

[0118] like Fig. 9 As shown, in some embodiments, the first recessed area 201 may include a first inclined section 2011. In the direction from top to bottom of the first recessed area 201, the first inclined section 2011 may extend downwardly from a side close to the first air outlet 402 toward a side close to the door body 3.

[0119] Among them, by providing a first inclined section 2011 on the side of the first recessed area 201 close to the first air outlet 402, the first inclined section 2011 is inclined from the rear of the top of the box 2 toward the side of the door body 3. When the airflow in the air duct 401 flows to the first recessed area 201 through the first air outlet 402, it can flow downward and toward the side of the door body 3 under the guidance of the first inclined section 2011. In this way, the airflow can be gradually guided downward to the side close to the door body 3, which is beneficial for the airflow below to flow back along the return air channel 301 on the back side of the door body 3 to the air intake port 404 at the top, thereby further optimizing the airflow path.

[0120] like Fig.10As shown, in some embodiments, the first recessed area 201 may include a first vertical section 2012. One end of the first vertical section 2012 may be connected to the lower end of the first inclined section 2011. The first vertical section 2012 may be arranged to extend vertically downward from the lower end of the first inclined section 2011. Through the arrangement of the first vertical section 2012, after the airflow flows to the lower end of the first inclined section 2011, it can continue to flow smoothly downward along the first vertical section 2012 to the bottom of the refrigeration compartment 101.

[0121] like Fig.10 As shown, in some embodiments, the second recessed area 202 may include a second inclined section 2021. In the direction from top to bottom of the second recessed area 202, the second inclined section 2021 may extend downwardly from the side close to the second air outlet 403 toward the side close to the door body 3, which is conducive to the bottom area of ​​the refrigeration compartment 101 to more smoothly return to the top air intake port 404 through the return air channel 301 formed between the back side of the door body 3 and the shelf 7.

[0122] Among them, by providing a second inclined section 2021 on the side of the second recessed area 202 close to the second air outlet 403, the second inclined section 2021 is inclined from the rear of the top of the box 2 toward the side of the door body 3. When the airflow in the air duct 401 flows to the second recessed area 202 through the second air outlet 403, it can flow downward and toward the side of the door body 3 under the guidance of the second inclined section 2021. In this way, the airflow can be gradually guided downward to the side close to the door body 3, which is beneficial for the airflow below to flow back to the air intake port 404 at the top along the return air channel 301 on the back side of the door body 3, thereby further optimizing the airflow path.

[0123] like Fig.11 As shown, in some embodiments, the second recessed area 202 may include a second vertical section 2022. One end of the second vertical section 2022 may be connected to the lower end of the second inclined section 2021. The second vertical section 2022 may be arranged to extend vertically downward from the lower end of the second inclined section 2021. Through the arrangement of the second vertical section 2022, after the airflow flows to the lower end of the second inclined section 2021, it can continue to flow smoothly downward along the second vertical section 2022 to the bottom of the refrigeration compartment 101.

[0124] like Fig.11 As shown, in some embodiments, the first recessed area 201 further includes a first mounting groove 2013 and a second mounting groove 2014 extending vertically. The first mounting groove 2013 and the second mounting groove 2014 are arranged in a front-to-back spacing. The first mounting groove 2013 and the second mounting groove 2014 can be used to install the shelf support column 9 connected to the shelf 7, thereby supporting the side of the shelf 7 close to the first side wall 21.

[0125] like Fig.11 As shown, in some embodiments, the second recessed area 202 further includes a third mounting groove 2023 and a fourth mounting groove 2024 extending vertically. The third mounting groove 2023 and the fourth mounting groove 2024 are arranged in a front-to-back spacing. The third mounting groove 2023 and the fourth mounting groove 2024 can be used to install the shelf support column 9 connected to the shelf 7, thereby supporting the side of the shelf 7 close to the second side wall 22.

[0126] Fig.12 for Figure 1 Schematic diagram of the stroke tract.

[0127] like Fig.12 As shown, in some embodiments, the refrigerator may include an air duct cover plate 4. The air duct cover plate 4 may be arranged horizontally on the top of the box 2. The first evaporation portion 51, the second evaporation portion 52 and the fan 6 may be arranged on the air duct cover plate 4. An air duct 401 may be formed between the air duct cover plate 4 and the top of the box 2. The air duct cover plate 4 is arranged horizontally on the top of the box 2, and the air duct cover plate 4 may be used to install the first evaporation portion 51, the second evaporation portion 52 and the fan 6, so that the first evaporation portion 51, the second evaporation portion 52 and the fan 6 are integrated on the air duct cover plate 4.

[0128] like Fig.12 As shown, in some embodiments, the refrigerator may include a first air outlet plate 41. The first air outlet plate 41 may be arranged to extend downward from one end of the air duct cover plate 4 close to the first side wall 21. A first air outlet 402 may be formed between the first air guide plate 43 and the first side wall 21.

[0129] like Figure 6 and Fig.12 As shown, in some embodiments, the refrigerator may include a second air outlet plate 42. The second air outlet plate 42 may be arranged to extend downward from one end of the air duct cover plate 4 close to the second side wall 22. A second air outlet 403 may be formed between the second air guide plate 44 and the second side wall 22.

[0130] Among them, the first air outlet plate 41 and the second air outlet plate 42 extend downward from both ends of the air duct cover plate 4 respectively, and form a first air outlet 402 and a second air outlet 403 between the side walls of the box 2, so that the airflow flowing to the refrigeration compartment 101 can flow smoothly downward from the top along the first air outlet plate 41 and the second air outlet plate 42 to the two sides of the refrigeration compartment 101, further enhancing the guiding effect of the airflow and improving the refrigeration efficiency.

[0131] Fig.13 for Figure 1 A schematic diagram of the first air guide plate in a state; Fig.14 for Fig.13 Schematic diagram of the first air guide plate in another state.

[0132] like Fig.13 As shown, in some embodiments, the refrigerator may include a first air guide plate 43. The first air guide plate 43 may be disposed between the first air outlet plate 41 and the first side wall 21. A plurality of first air guide plates 43 may be provided. The plurality of first air guide plates 43 may separate the first air outlet 402 into a plurality of first sub-channels 405, so that the airflow is transported downward along the plurality of first sub-channels 405.

[0133] Among them, by arranging a plurality of first air guide plates 43 in the first air outlet 402, the first air outlet 402 is divided into a plurality of first sub-channels 405. In this way, each first sub-channel 405 independently transports cold air, so that the airflow can be evenly distributed in the area along the first side wall 21, and can be more evenly transported downward along the first air outlet 402 to the refrigeration chamber 101, thereby avoiding the cold air concentration and uneven cooling caused by a single air outlet.

[0134] like Fig.12 and Fig.13 As shown, in some embodiments, the first air guide plate 43 is rotatably disposed between the first air outlet plate 41 and the first side wall 21 to change the blowing angle of the airflow conveyed downward by the first sub-channel 405. In this way, the user can flexibly adjust the blowing angle of the first side wall 21 according to actual needs, so that the airflow can be blown to the target area in the refrigeration compartment 101 more accurately.

[0135] Among them, the user can adjust the wind guide angle of the first sub-channel 405 by rotating the first air guide plate 43, and optimize the distribution path of the cold air according to the user's needs. Specifically, the first air guide plate 43 can be rotated to tilt forward, so that the airflow is more concentrated to blow toward the side of the door body 3, thereby achieving rapid cooling of the items on the front side of the refrigerator cabinet. In other application scenarios, the user can also rotate the first air guide plate 43 to tilt backward, so that the airflow is more concentrated to blow toward the side away from the door body 3, thereby achieving rapid cooling of the items on the back side of the refrigerator cabinet.

[0136] like Fig.13 As shown, in some embodiments, a first clamping position 45 and a second clamping position 46 may be respectively provided on one side of the first air outlet plate 41 facing the first side wall 21. The first clamping position 45 and the second clamping position 46 may be respectively clamped with one end of the first air outlet plate 41 to fix the first air outlet plate 41.

[0137] Specifically, Fig.13 and Fig.14 As shown, the upper end of the first air guide plate 43 can be rotatably connected to the first air outlet plate 41 by providing a first rotating shaft, and the lower end of the first air guide plate 43 can be provided with a first protrusion (not shown in the figure) to be clamped with the first clamping position 45 or the second clamping position 46, so that the first air guide plate 43 is fixed as a whole.

[0138] like Fig.13 As shown, when the first air guide plate 43 rotates to engage with the first engaging position 45, the first air guide plate 43 can be arranged to extend downwardly and obliquely toward the side of the door body 3 to guide the airflow flowing through the first sub-channel 405 to be transported obliquely and downwardly toward the side of the door body 3.

[0139] like Fig.14 As shown, when the first air guide plate 43 rotates to engage with the second engaging position 46, the first air guide plate 43 can be vertically extended and arranged between the first air outlet plate 41 and the first side wall 21 to guide the airflow flowing through the first sub-channel 405 to be transported downward.

[0140] Among them, when the first air guide plate 43 is engaged with the first engaging position 45, the first air guide plate 43 extends obliquely downward so that the first sub-channel 405 formed between the multiple first air guide plates 43 can concentrate the airflow on one side of the first side wall 21 to blow toward the front side, thereby achieving rapid cooling of the local area on the front side of the refrigeration chamber 101.

[0141] When the first air guide plate 43 is engaged with the second engaging position 46, the first air guide plate 43 can extend vertically downward so that the first sub-channel 405 formed between the plurality of first air guide plates 43 can evenly transport the airflow on one side of the first side wall 21 downward along the first side wall 21, thereby making the temperature of each area in the refrigeration compartment 101 more stable and uniform, reducing the temperature difference, and improving the refrigeration effect.

[0142] Fig.15 for Figure 1 A schematic diagram of the second air guide plate in a state; Fig.16 for Fig.15 Schematic diagram of the second air guide plate in another state.

[0143] like Fig.15 and Fig.16 As shown, in some embodiments, the refrigerator may include a second air guide plate 44. The second air guide plate 44 may be disposed between the second air outlet plate 42 and the second side wall 22. A plurality of second air guide plates 44 may be provided. The plurality of second air guide plates 44 may separate the second air outlet 403 into a plurality of second sub-channels 406, so that the airflow is transported downward along the plurality of second sub-channels 406.

[0144] Among them, by arranging a plurality of second air guide plates 44 in the second air outlet 403, the second air outlet 403 is divided into a plurality of second sub-channels 406. In this way, each second sub-channel 406 independently transports cold air, so that the airflow can be evenly distributed in the area along the first side wall 21, and can be more evenly transported downward along the second air outlet 403 to the refrigeration chamber 101, thereby avoiding the cold air concentration and uneven cooling caused by a single two air outlets.

[0145] In some embodiments, the second air guide plate 44 is rotatably disposed between the second air outlet plate 42 and the second side wall 22 to change the blowing angle of the airflow conveyed downward by the first sub-channel 405. In this way, the user can flexibly adjust the blowing angle of the second side wall 22 according to actual needs, so that the airflow can be blown to the target area in the refrigeration compartment 101 more accurately.

[0146] Among them, the user can adjust the wind guide angle of the second sub-channel 406 by rotating the second wind guide plate 44, and optimize the distribution path of the cold air according to the user's needs. Specifically, the second wind guide plate 44 can be rotated to tilt forward, so that the airflow is more concentrated to blow toward the side of the door body 3, thereby achieving rapid cooling of the items on the front side of the refrigerator cabinet. In other application scenarios, the user can also rotate the second wind guide plate 44 to tilt backward, so that the airflow is more concentrated to blow toward the side away from the door body 3, thereby achieving rapid cooling of the items on the back side of the refrigerator cabinet.

[0147] Specifically, the first air guide plate 43 and the second air guide plate 44 are used in cooperation so that the airflows flowing on both sides of the first side wall 21 and the second side wall 22 are adjusted synchronously, thereby achieving a better airflow distribution effect.

[0148] like Fig.15 As shown, in some embodiments, a third snap-in position 47 and a fourth snap-in position 48 may be provided on one side of the second air outlet plate 42 facing the second side wall 22. The third snap-in position 47 and the fourth snap-in position 48 may be snap-in with one end of the second air outlet plate 42, respectively, to fix the second air outlet plate 42.

[0149] Specifically, the upper end of the second air guide plate 44 can be rotatably connected to the second air outlet plate 42 via a second rotating shaft, and the lower end of the second air guide plate 44 can be provided with a second protrusion (not shown in the figure) to be clamped with the third clamping position 47 or the fourth clamping position 48 to fix the entire second air guide plate 44.

[0150] like Fig.15 As shown, when the second air guide plate 44 rotates to engage with the third engaging position 47, the second air guide plate 44 can be arranged to extend obliquely downward toward the side of the door body 3 to guide the airflow flowing through the second sub-channel 406 to be transported obliquely downward toward the side of the door body 3;

[0151] like Fig.16 As shown, when the second air guide plate 44 rotates to engage with the fourth engaging position 48, the second air guide plate 44 first vertically extends and is arranged between the second air outlet plate 42 and the second side wall 22 to guide the airflow flowing through the second sub-channel 406 to be transported downward.

[0152] Among them, when the second air guide plate 44 is engaged with the third engaging position 47, the second air guide plate 44 extends obliquely downward so that the second sub-channel 406 formed between the plurality of second air guide plates 44 can concentrate the airflow on one side of the second side wall 22 to blow toward the front side, thereby achieving rapid cooling of the local area on the front side of the refrigeration chamber 101.

[0153] When the second air guide plate 44 is engaged with the fourth engaging position 48, the second air guide plate 44 can extend vertically downward so that the second sub-channel 406 formed between the plurality of second air guide plates 44 can evenly transport the airflow on one side of the second side wall 22 downward along the second side wall 22, thereby making the temperature of each area in the refrigeration compartment 101 more stable and uniform, reducing the temperature difference, and improving the refrigeration effect.

[0154] It should be noted that the first air guide plate 43 and the second air guide plate 44 can be rotated manually or automatically adjusted by designing a driving structure.

[0155] It should be noted that, in some other embodiments, the first air guide plate 43 may be fixed on the first air outlet plate 41 , and the second air guide plate 44 may be fixed on the second air outlet plate 42 .

[0156] Fig.17 for Figure 1 Schematic diagram of the evaporator; Fig.18 for Fig. 9 A partial enlarged view of point D.

[0157] like Fig.17 As shown, in some embodiments, the first evaporation portion 51 is integrally connected with the second evaporation portion 52 , so that the first evaporation portion 51 and the second evaporation portion 52 are respectively formed in the same evaporator 5 .

[0158] Among them, by integrating the first evaporation part 51 and the second evaporation part 52 in the same evaporator 5, the integrated setting of the first evaporation part 51 and the second evaporation part 52 can simplify the evaporator 5 and the connection structure between the evaporator 5 and other components of the refrigeration system, avoiding the complex connecting pipes and additional space occupation required for two independent evaporation parts, thereby making the layout of the evaporator 5 in the refrigerator more compact, optimizing the space utilization of the refrigerator, and leaving more space for the air duct 401 or other components, thereby making the internal structure of the refrigeration device more compact.

[0159] It should be noted that, in some other embodiments, the first evaporation portion 51 may be configured as an independent evaporator 5 . The second evaporation portion 52 may be configured as an independent evaporator 5 .

[0160] like Fig.18As shown, in some embodiments, the evaporator 5 may include a first evaporation tube 511 and a second evaporation tube 521. The first evaporation tube 511 and the second evaporation tube 521 may be disposed in the air duct 401. The first evaporation tube 511 and the second evaporation tube 521 may be disposed on opposite sides of the fan 6. One end of the first evaporation tube 511 may be connected to one end of the second evaporation tube 521. The first evaporation tube 511 and the second evaporation tube 521 are distributed on opposite sides of the fan 6. The first evaporation tube 511 and the second evaporation tube 521 may cool the airflow flowing toward the first side wall 21 and the airflow flowing toward the second side wall 22, respectively.

[0161] like Fig.17 As shown, in some embodiments, the evaporator 5 may include a third evaporation tube 522 and a fourth evaporation tube 512. The third evaporation tube 522 and the fourth evaporation tube 512 may be arranged in the air duct 401. The third evaporation tube 522 and the fourth evaporation tube 512 may be arranged on opposite sides of the fan 6. One end of the third evaporation tube 522 may be connected to an end of the second evaporation tube 521 away from the first evaporation tube 511; the fourth evaporation tube 512 may be arranged with an interval between the first evaporation tube 511 and the lower part. One end of the fourth evaporation tube 512 may be connected to an end of the third evaporation tube 522 away from the second evaporation tube 521. Among them, the first evaporation tube 511 and the fourth evaporation tube 512 may form a first evaporation portion 51. The second evaporation tube 521 and the third evaporation tube 522 may form a second evaporation portion 52.

[0162] Among them, the first evaporation tube 511 and the fourth evaporation tube 512 are configured as the first evaporation part 51, the second evaporation tube 521 and the third evaporation tube 522 are configured as the second evaporation part 52, and the first evaporation tube 511 and the fourth evaporation tube 512, the second evaporation tube 521 and the third evaporation tube 522 are arranged in an upper and lower interval. In this way, the double-layer heat exchange structure in which the first evaporation part 51 and the second evaporation part 52 are respectively arranged in an upper and lower position can not only increase the heat exchange area, further improve the heat exchange efficiency when the air flows through the evaporation tube, but also reasonably utilize the vertical space in the air duct 401. On the other hand, the first evaporation tube 511, the second evaporation tube 521, the third evaporation tube 522 and the fourth evaporation tube 512 are connected in sequence, so that the refrigerant can flow in from the first evaporation part 51 and then flow out through the first evaporation part 51, or the refrigerant can flow in from the second evaporation part 52 and then flow out through the second evaporation part 52, which is conducive to the centralized distribution of the pipelines of the evaporator 5, making the structure of the evaporator 5 more compact.

[0163] like Fig.16As shown, in some embodiments, the evaporator 5 may include a first inlet and outlet pipe 53. The first inlet and outlet pipe 53 may be connected to an end of the first evaporation tube 511 away from the second evaporation tube 521. The first inlet and outlet pipe 53 may be used to allow the refrigerant to flow into the first evaporation portion 51 and the second evaporation portion 52. An end of the first inlet and outlet pipe 53 away from the first evaporation tube 511 may extend out of the air duct 401 and extend downward.

[0164] like Fig.17 As shown, in some embodiments, the evaporator 5 may include a second inlet and outlet pipe 54. The second inlet and outlet pipe 54 may be connected to an end of the fourth evaporation tube 512 away from the third evaporation tube 522. The second inlet and outlet pipe 54 may be used to allow the refrigerant to flow out of the first evaporation portion 51 and the second evaporation portion 52. An end of the second inlet and outlet pipe 54 away from the fourth evaporation tube 512 may extend out of the air duct 401 and extend downward.

[0165] Specifically, the refrigerant flows through the first evaporation tube 511, the second evaporation tube 521, the third evaporation tube 522 and the fourth evaporation tube 512 in sequence through the first inlet and outlet pipe 53, and then flows out of the evaporator 5 through the second inlet and outlet pipe 54. Since the first evaporation tube 511 and the fourth evaporation tube 512 are arranged at intervals up and down and configured as the first evaporation part 51, that is, the first inlet and outlet pipe 53 and the second inlet and outlet pipe 54 are both distributed on one side of the first evaporation part 51, the pipes connecting the evaporator 5 to the outside can be arranged on the same side, thereby reducing part of the space of the pipes connecting the evaporator 5 to the outside, further improving the space utilization rate of the refrigerator, and helping to increase the product usage space of the refrigerator.

[0166] In some embodiments, the first inlet and outlet pipe 53 and the second inlet and outlet pipe 54 can be arranged to extend vertically downward along the first side wall 21 , and the bottom of the first inlet and outlet pipe 53 and the bottom of the second inlet and outlet pipe 54 can extend into the press chamber at the bottom of the box body 1 .

[0167] like Figure 5 As shown, in some embodiments, the box 2 may include a third side wall 23. The third side wall 23 may be disposed at the back of the refrigeration compartment 101. The third side wall 23 may be disposed between the rear sides of the first side wall 21 and the second side wall 22. The installation area 203 may be recessed on the front wall of the third side wall 23. The portion of the first inlet and outlet pipe 53 extending out of the air duct 401 may be installed in the installation area 203, and the portion of the second inlet and outlet pipe 54 extending out of the air duct 401 may be installed in the installation area 203.

[0168] like Fig. 9 and Fig.18As shown, specifically, by recessing the installation area 203 on the front wall of the third side wall 23, a dedicated installation space is provided for the first inlet and outlet pipe 53 and the second inlet and outlet pipe 54, so that the first inlet and outlet pipe 53 and the second inlet and outlet pipe 54 do not occupy the space of the refrigeration compartment 101 inside the refrigerator, and the first inlet and outlet pipe 53 and the second inlet and outlet pipe 54 do not hang or protrude randomly in the box body 1, thereby optimizing space utilization and making the appearance of the refrigeration device neater.

[0169] like Figure 5 As shown, in some embodiments, the box 2 may include a decorative plate 8. The decorative plate 8 may be covered at the front opening of the installation area 203. In this way, the first inlet and outlet pipe 53 and the second inlet and outlet pipe 54 may be installed on the installation area 203 at the back of the decorative plate 8, and the decorative plate 8 may effectively shield the pipes in the installation area 203, making the appearance of the interior of the refrigerator more neat and beautiful, and improving the visual experience of the user.

[0170] In some embodiments, the installation area 203 may be disposed on a side of the third side wall 23 that is disposed close to the first side wall 21 , and correspondingly, two sides of the decorative panel 8 may be connected to the first side wall 21 and the third side wall 23 , respectively.

[0171] The above are only specific implementations of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application.
