Description

Technical Field

[0001] This utility model relates to the field of refrigeration electrical technology, and mainly to a refrigeration device. Background Technology

[0002] Refrigeration equipment is a device that maintains a constant low temperature to store goods, and it is widely used in modern life and industrial production. For example, refrigerators and freezers have refrigeration compartments that create a refrigerated environment for the items to be refrigerated.

[0003] Currently, the cooling air ducts in the cooling room are mainly located at the back. The back air ducts contain fans and evaporators. After the airflow passes through the evaporator, it forms cold air that can cool the cooling room.

[0004] In a double-door refrigerator, a middle partition needs to be installed at the opening of the cooling compartment. Correspondingly, a mounting plate needs to be installed on the rear air duct of the cooling compartment to support the shelves on both sides. When the rear air duct needs to be disassembled to repair or replace internal components, the entire rear air duct baffle needs to be removed. However, because the mounting plate is in the front of the baffle, disassembly is inconvenient. Utility Model Content

[0005] The purpose of this invention is to provide a cooling device that can improve the ease of disassembling the fan in the back air duct.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: One aspect of this application provides a refrigeration device, including a housing forming the outer shell of the refrigeration device; a liner, the housing disposed within the housing, the liner containing a refrigeration chamber; shelves, at least two sets of shelves arranged laterally adjacent to each other within the refrigeration chamber; a mounting plate disposed on the back of the refrigeration chamber, extending along the height direction of the refrigeration chamber, the mounting plate being located between the two sets of shelves and used to support the rear side of the shelves; and a refrigeration duct disposed within the liner, the refrigeration duct including a mounting base disposed on the rear wall within the liner, the mounting base having a first air cavity and a second air cavity arranged laterally adjacent to each other; a first fan disposed in the first air cavity, and a second fan disposed in the second air cavity; A first baffle is detachably installed over the first air cavity and exposed in the refrigeration chamber; a second baffle is installed over the second air cavity and exposed in the refrigeration chamber; wherein, the side of the first baffle near the second baffle is spaced apart on the back side of the mounting plate, and the side of the second baffle near the first baffle is spaced apart on the back side of the mounting plate, so that a gap is formed between the adjacent parts of the first baffle and the second baffle and the back side of the mounting plate; the side of the first baffle near the second baffle can be detached from the gap, exposing the first fan in the refrigeration chamber; the side of the second baffle near the first baffle can be detached from the gap, exposing the second fan in the refrigeration chamber.

[0007] The above technical solution has the following advantages or beneficial effects: By providing a first baffle and a second baffle on both sides of the corresponding refrigeration compartment on the mounting base, an independent fan installation unit is formed. The first baffle and the second baffle are detachably mounted on the mounting base. Maintenance personnel can repair or replace the fan on the corresponding side by removing the baffle on the corresponding side. Furthermore, since the separately configured first and second baffles are smaller in size than the integrated baffles, interference with the front mounting plate can be effectively avoided, greatly facilitating the disassembly and assembly process for maintenance personnel. Furthermore, the adjacent sides of the first and second baffles are spaced apart on the back side of the mounting plate, thus forming an interval space. This interval space provides a passage for disassembly operations, allowing maintenance personnel to reach into the interval space through the refrigeration chamber to disassemble the first or second baffle. The operation path is not obstructed by the mounting plate, solving the problem of the mounting plate blocking disassembly. After the user removes the first or second baffle, the first or second fan is exposed in the refrigeration chamber. Maintenance personnel can directly remove or observe the first and second fans through the refrigeration chamber, simplifying the refrigeration duct maintenance process and improving the efficiency of refrigeration duct maintenance.

[0008] In some embodiments of this application, a refrigeration device is provided, wherein a partition is provided inside the mounting base, the partition dividing the internal space of the mounting base into a first air cavity and a second air cavity; the partition is located on the back side of the mounting plate; the side of the first baffle near the second baffle is engaged with the partition; the side of the second baffle near the first baffle is engaged with the partition.

[0009] Another technical solution described above has the following advantages or beneficial effects: By setting a partition inside the mounting base, independent first and second air cavities can be formed within the mounting base, reducing airflow crosstalk between the first and second air cavities, allowing the first and second fans to operate independently without interference. The side of the first baffle closest to the second baffle is engaged with the partition, allowing maintenance personnel to quickly disassemble the baffle without tools, and the disassembly process is not obstructed by the mounting plate, providing ample operating space.

[0010] In some embodiments of this application, a refrigeration device is provided, wherein the partition is provided with a first slot and a second slot respectively; the first baffle is provided with a first buckle on the side near the second baffle, and the first buckle engages with the first slot; the second baffle is provided with a second buckle on the side near the first baffle, and the second buckle engages with the second slot.

[0011] Another technical solution in the above-mentioned technical solution has the following advantages or beneficial effects: By providing a first buckle that engages with the first slot on the first baffle and a second buckle that engages with the second slot on the second baffle, maintenance personnel do not need tools such as screwdrivers. They only need to reach into the space between the baffles, align the buckles with the positions, and press them to cause the first or second buckle to elastically deform and disengage from the slot, thus allowing the first baffle to be removed from the partition and the second baffle to be removed from the partition. This avoids the use of screws at the joint between the first and second baffles, and avoids increasing the difficulty of disassembly and installation by using tools in the narrow space between the baffles, thereby reducing the difficulty of disassembly and installation and improving the efficiency of installation and disassembly.

[0012] In some embodiments of this application, a refrigeration device is provided. The first buckle includes a first elastic arm, one end of which is connected to the side of the first baffle near the second baffle, and the other end of which extends toward the front side of the first baffle. A first engaging portion is provided on the side of the first elastic arm near the second baffle. The first elastic arm can abut against the first slot, and the first engaging portion engages with the side wall of the first slot, so that the first baffle is fixed on the partition.

[0013] Another technical solution described above has the following advantages or beneficial effects: By connecting one end of the first elastic arm to the side of the first baffle and extending the other end forward to form a cantilever structure, the first elastic arm can have elastic deformation capability. When the first baffle is installed, the first elastic arm is compressed and deformed, allowing the first snap-fit ​​part to slide smoothly into the slot. After installation, the first elastic arm returns to its original shape, allowing the first snap-fit ​​part to form an interference fit with the side wall of the first slot, thereby ensuring a firm fixation between the first baffle and the mounting base, preventing it from falling off even under vibration or impact.

[0014] In some embodiments of this application, a refrigeration device is provided, wherein the first elastic arm includes a first extension portion connected to the side of the first baffle near the second baffle and extending toward the back side of the first baffle; a first bending portion extending from the rear end of the first extension portion toward the front side of the first baffle, the first bending arm being located on the side of the first extension portion near the second baffle; the side of the first bending portion toward the second baffle is provided with a first snap-fit ​​portion; the front end of the first bending portion protrudes from the front wall of the first baffle and extends into the interval space. Another technical solution described above has the following advantages or beneficial effects: by connecting one end of the first extension to one side of the first baffle and extending the other end rearward, the first extension can provide elastic support for the entire first elastic arm. Maintenance personnel only need to press the front end of the bend protruding into the interval space with their fingers to allow the first snap-fit ​​part to disengage from the first slot through the deformation generated by the first bend, eliminating the need for additional tools to disassemble and install the first baffle. This also reduces the difficulty for users to operate within the narrow interval space created by the back of the mounting plate.

[0015] In some embodiments of this application, a refrigeration device is provided, wherein the second buckle includes a second elastic arm, one end of which is connected to the side of the second baffle near the first baffle, and the other end of which extends toward the front side of the second baffle; a second engaging portion is provided on the side of the second elastic arm near the first baffle; the second elastic arm is capable of abutting against the second slot, and the second engaging portion engages with the side wall of the second slot, so that the second baffle is fixed on the partition.

[0016] Another technical solution described above has the following advantages or beneficial effects: By connecting one end of the second elastic arm to the side of the second baffle and extending the other end forward to form a cantilever structure, the second elastic arm can have elastic deformation capability. When the second baffle is installed, the second elastic arm is compressed and deformed, allowing the second snap-fit ​​part to slide smoothly into the slot. After installation, the second elastic arm returns to its original shape, allowing the second snap-fit ​​part to form an interference fit with the side wall of the second slot, thereby ensuring a firm fixation between the second baffle and the mounting base, preventing it from falling off even under vibration or impact.

[0017] In some embodiments of this application, a refrigeration device is provided, wherein the second elastic arm includes a second extension portion connected to the side of the second baffle near the first baffle and extending toward the back side of the second baffle; a second bending portion extending from the rear end of the second extension portion toward the front side of the second baffle, the second bending portion being located on the side of the second extension portion near the first baffle; a second snap-fit ​​portion is provided on the side of the second bending portion toward the first baffle; the front end of the second bending portion protrudes from the front wall of the second baffle and extends into the interval space. Another technical solution described above has the following advantages or beneficial effects: by connecting one end of the second extension to one side of the second baffle and extending the other end rearward, the second extension can provide elastic support for the entire second elastic arm. Maintenance personnel only need to press the front end of the bend protruding into the interval space with their fingers to allow the second snap-fit ​​part to disengage from the second slot through the deformation generated by the second bend, eliminating the need for additional tools to disassemble and install the second baffle. This also reduces the difficulty for users operating within the narrow interval space created by the back of the mounting plate.

[0018] In some embodiments of this application, a refrigeration device is provided. A first air cavity is provided with a first air duct wall, which is arranged circumferentially around a first fan. The first air duct wall and the side wall of the mounting base form the first air cavity. A first baffle is provided with a first air intake, which is arranged opposite to and communicates with the first air cavity. The first air intake connects the refrigeration chamber and the first air cavity. A second air cavity is provided with a second air duct wall, which is arranged circumferentially around a second fan. The second air duct wall and the side wall of the mounting base form the second air cavity. A second baffle is provided with a second air intake, which is arranged opposite to and communicates with the second air cavity. The second air intake connects the refrigeration chamber and the second air cavity.

[0019] Another technical solution described above has the following advantages or beneficial effects: By arranging a first air duct wall around the first fan in the circumference, the first air duct wall and the side wall of the mounting base together form a complete first air cavity, thus constituting the airflow channel of the first fan. Similarly, by arranging a first air duct wall around the second fan in the circumference, the second air duct wall and the side wall of the mounting base together form a complete second air cavity, thus constituting the airflow channel of the second fan. In this way, the first air duct wall can form a channel that constrains airflow along the circumference of the first fan, forcing the cold air to flow only along the path guided by the air duct wall. After the airflow enters the first air cavity through the first air inlet, it flows to the cooling room through the air outlet of the first air cavity, thus avoiding airflow cross-flow between the first and second air cavities, and also preventing the formation of vortices within the first air cavity.

[0020] In some embodiments of this application, a refrigeration device is provided, wherein the mounting plate is disposed at intervals on the front side of the rear wall inside the box liner, the upper end of the mounting plate is connected to the top wall of the box liner, and the lower end of the box liner is connected to the bottom wall of the box liner.

[0021] Another technical solution described above has the following advantages or beneficial effects: By connecting the upper and lower ends of the mounting plate to the bottom and top walls of the refrigeration chamber, respectively, the upper end of the mounting plate can extend to the top of the refrigeration chamber, and the lower end can extend to the bottom of the refrigeration chamber, thereby supporting multiple shelves in various height directions of the refrigeration chamber. Furthermore, since the mounting plates are spaced apart on the front side of the rear wall inside the refrigeration chamber, the space between the mounting plates and the rear wall can be used to arrange heat exchanger pipes, drain pipes, and other structures, without occupying additional internal space of the refrigeration chamber, and also improving the aesthetics of the refrigeration chamber interior.

[0022] In some embodiments of this application, a refrigeration device is provided. The refrigeration duct further includes a lower baffle, which is disposed on the back of the housing and located at the lower end of the mounting base. The lower baffle and the back of the housing enclose a heat exchange cavity. The first air cavity and the second air cavity are respectively connected to the heat exchange cavity. The refrigeration device further includes an evaporator, which is disposed in the heat exchange cavity. The refrigeration device further includes a water receiving component, which is fixed to the inner side of the lower baffle and located in the heat exchange cavity. The water receiving component is arranged at the lower end of the evaporator and is used to collect condensate in the heat exchange cavity.

[0023] Another technical solution mentioned above has the following advantages or beneficial effects: a heat exchange cavity is formed between the lower baffle and the back of the liner. By setting an evaporator in the heat exchange cavity, the evaporator can serve as a common heat exchange element for both the first and second air cavities, eliminating the need for a separate evaporator in each air cavity. This effectively ensures that both sides of the refrigeration chamber can obtain a stable and consistent supply of cold air, which is beneficial for achieving temperature uniformity at different locations inside the refrigeration chamber. It also avoids the problems of complex structure and inconsistent temperature on both sides of the refrigeration chamber caused by dual evaporators. Attached Figure Description

[0030] The refrigeration device in the embodiments of the present invention can be a freezer, refrigerator, or other refrigeration cabinet. The following uses a refrigerator as an example to describe in detail the improved technical solution of the refrigeration device in the embodiments of the invention.

[0031] Figure 1 This is a schematic diagram of a refrigeration device according to an embodiment of this application.

[0032] like Figure 1 As shown, the refrigeration device provided in this embodiment of the present invention includes a housing 1. The housing 1 can adopt a hollow structure such as a cuboid. The housing 1 forms the outer shell of the refrigeration device. It should be noted that the housing 1 can also adopt a hollow shell structure of other shapes.

[0033] Figure 2 for Figure 1 A partial schematic diagram.

[0034] like Figure 2 As shown, in some embodiments, the refrigeration device may include a cabinet liner 2. A refrigeration compartment 201 may be formed inside the cabinet liner 2, and the cabinet body 1 has a refrigeration compartment 201, which can serve as an independent storage space. The refrigeration compartment 201 may have an opening, through which a user can store food. Multiple refrigeration compartments 201 may be provided.

[0035] In some embodiments, multiple refrigeration chambers 201 may be provided, which may be freezers, refrigerators, and variable temperature chambers, etc., to meet different refrigeration needs such as freezing, refrigeration, and variable temperature according to different types of food, and to store items that need to be refrigerated or frozen. The multiple refrigeration chambers 201 may be arranged vertically or horizontally.

[0036] like Figure 1 As shown, in some embodiments, the refrigeration device may include a door 11. The door 11 is movably mounted on the housing 1 and is used to open or close the refrigeration compartment 201.

[0037] Multiple doors 11 can be provided, and multiple doors 11 can be correspondingly provided on multiple refrigeration compartments 201. The doors 11 can be movably provided on the cabinet 1 by means of rotation or sliding.

[0038] In some embodiments, the refrigeration system includes a refrigeration system (not shown in the figure). The refrigeration system may be located inside the cabinet 1. The refrigeration system is used to provide cold air to the interior of the refrigerator to maintain a low-temperature environment in each refrigeration compartment 201.

[0039] In some embodiments, the refrigeration system includes a compressor (not shown). The compressor is the power source for the refrigeration cycle, drawing in low-temperature, low-pressure refrigerant gas and compressing it into a high-temperature, high-pressure gas. The compressor can deliver the high-temperature, high-pressure refrigerant to the condenser.

[0040] In some embodiments, the refrigeration system includes a condenser (not shown). The condenser can be used to receive refrigerant flowing out of the compressor, cooling the high-temperature, high-pressure refrigerant gas from the compressor and converting it into a liquid state. The condenser can transfer heat from the refrigerant to the surrounding air, thereby lowering the temperature of the refrigerant.

[0041] In some embodiments, the refrigeration system includes a throttling device (not shown). A condenser can deliver condensed refrigerant to the throttling device. The throttling device may be a capillary tube. The throttling device can be used to reduce the pressure of the refrigerant.

[0042] In some embodiments, the refrigeration system includes an evaporator 14 (not shown). A throttling device can deliver a throttled and depressurized refrigerant into the evaporator 14. The evaporator 14 can be used for the refrigerant vapor to evaporate and boil, thereby absorbing heat from the surrounding medium.

[0043] In some embodiments, the compressor, condenser, throttling device, and evaporator 14 can be connected in sequence to form a refrigeration circuit. The refrigerant can circulate within the refrigeration circuit to achieve refrigeration of the interior of the housing 1.

[0044] like Figure 2 As shown, in some embodiments, the refrigeration device includes shelves 12, which can be laterally adjacent to each other in the refrigeration chamber 201 to achieve layered storage and improve the space utilization of the refrigeration chamber 201. At least two sets of shelves 12 can be provided, arranged laterally adjacent to each other within the refrigeration compartment 201. One set of shelves 12 can have multiple units, arranged vertically at intervals on one side of the refrigeration compartment 201; the other set of shelves 12 can have multiple units, arranged vertically at intervals on the other side of the refrigeration compartment 201. This arrangement of shelves 12 allows for adaptation to the symmetrical storage layout of a double-door refrigerator.

[0045] like Figure 2 As shown, in some embodiments, the refrigeration device includes a mounting plate 13, which is disposed at the back of the refrigeration chamber 201. The mounting plate 13 extends along the height direction of the refrigeration chamber 201 and is located between two sets of shelves 12, serving to support the rear side of the shelves 12. One side of the shelf 12 can be supported on a side wall of the liner 2, and the rear end of the other side of the shelf 12 can be supported on the mounting plate 13, so that the side of the shelf 12 away from the liner 2 can be stably positioned within the refrigeration chamber 201.

[0046] Figure 3 for Figure 2 A partial schematic diagram; Figure 4 for Figure 3 An exploded view. It should be noted that... Figure 3 for Figure 2 A schematic diagram showing the partial concealment of the outer shell and inner liner.

[0047] like Figure 3 and Figure 4 As shown, in some embodiments, the refrigeration device includes a refrigeration duct 300, which is disposed inside the liner 2 and is used to deliver heat exchange airflow to the refrigeration chamber 201.

[0048] The refrigeration duct 300 includes a mounting base 31 for mounting a fan. The mounting base 31 is located on the rear wall inside the casing 2, within the refrigeration chamber 201. The mounting base 31 has a first air chamber 310 and a second air chamber 320 arranged laterally adjacent to each other. A first fan 32 is installed in the first air chamber 310, and a second fan 33 is installed in the second air chamber 320. The first air chamber 310 and the second air chamber 320 on the mounting base 31 can correspond to the shelves 12 on both sides of the refrigeration chamber 201, thereby supplying air to the two sets of laterally adjacent shelves 12 areas separately, improving the temperature uniformity of the refrigeration chamber 201.

[0049] The refrigeration duct 300 includes a first baffle 341, which is detachably installed on the first air cavity 310 and exposed in the refrigeration chamber 201. When the first baffle 341 is installed on the first air cavity 310, it can cover the first air cavity 310 to form a sealed first air cavity 310, and can also prevent the first fan 32 from being directly exposed in the refrigeration chamber 201.

[0050] The refrigeration duct 300 includes a second baffle 342, which covers the second air cavity 320 and is exposed in the refrigeration chamber 201. When the second baffle 342 is installed in the second air cavity 320, it can cover the second air cavity 320 to form a sealed second air cavity 320, and can also prevent the second fan 33 from being directly exposed in the refrigeration chamber 201.

[0051] Figure 5 for Figure 3 A side view diagram.

[0052] Among them, such as Figure 5 As shown, the side of the first baffle 341 closest to the second baffle 342 is spaced apart on the back side of the mounting plate 13, and the side of the second baffle 342 closest to the first baffle 341 is spaced apart on the back side of the mounting plate 13, so that a gap space 101 is formed between the adjacent parts of the first baffle 341 and the second baffle 342 and the back side of the mounting plate 13.

[0053] The side of the first baffle 341 closest to the second baffle 342 can be detached from the partition space 101, exposing the first fan 32 to the cooling room 201. The side of the second baffle 342 closest to the first baffle 341 can be detached from the partition space 101, exposing the second fan 33 to the cooling room 201.

[0054] Specifically, a splicing seam can be formed at the adjacent position of the first baffle 341 and the second baffle 342. The mounting plate 13 is arranged at intervals on the front side of the splicing seam, so that an interval space 101 is formed between the mounting plate 13 and the front side of the adjacent position of the first baffle 341 and the second baffle 342. The mounting plate 13 can not only cover the splicing seam between the first baffle 341 and the second baffle 342 to improve the aesthetics of the interior of the refrigeration chamber 201, but the interval space 101 formed by it can also provide a passage for disassembly operations. The operator's hands or tools can be inserted into the interval space 101 from the side of the refrigeration chamber 201 to disassemble the adjacent side of the first baffle 341 and the second baffle 342. After the first baffle 341 is removed from the interval space 101, the first fan 32 is directly exposed in the refrigeration chamber 201, so that the operator can directly perform maintenance, replacement, etc. on the first fan 32. Correspondingly, after the second baffle 342 is removed from the partition space 101, the second fan 33 is directly exposed in the refrigeration compartment 201, allowing maintenance personnel to directly repair or replace the second fan 33. In this way, maintenance personnel can directly remove the first baffle 341 and the second baffle 342 without further disassembling the mounting plate 13 or even dismantling other structures in the air duct. This allows for direct inspection and replacement, effectively improving the ease of fan removal in double-door refrigerators.

[0055] In related technologies, since a partition plate 311 needs to be installed at the opening of the refrigeration compartment 201, a mounting plate 13 needs to be installed on the back air duct of the refrigeration compartment 201 to support the shelves 12 on both sides. When the refrigeration air duct 300 needs to be disassembled to repair or replace the internal components, the entire back air duct baffle needs to be removed. Since the mounting plate 13 blocks the front of the baffle, it obstructs the disassembly path of the baffle. This results in the need to remove the mounting plate 13 or disassemble the entire air duct before removing the baffle, which is cumbersome and has extremely low maintenance efficiency.

[0056] In the technical solution of this application, a first baffle 341 and a second baffle 342 are respectively provided on both sides of the refrigeration compartment 201 on the mounting base 31, thereby forming an independent fan installation unit. The first baffle 341 is detachably mounted on the mounting base 31, and the second baffle 342 is detachably mounted on the mounting base 31. Maintenance personnel can repair or replace the fan on the corresponding side by removing the baffle on the corresponding side. In particular, since the separately set first baffle 341 and second baffle 342 are smaller in size than the integrated baffle, interference with the front mounting plate 13 can be effectively avoided, greatly facilitating the disassembly and assembly process of maintenance personnel.

[0057] Furthermore, the adjacent sides of the first baffle 341 and the second baffle 342 are spaced apart on the back side of the mounting plate 13, thereby forming an interval space 101. The interval space 101 provides a passage for disassembly operations, allowing maintenance personnel to reach into the interval space 101 through the refrigeration chamber 201 to disassemble the first baffle 341 or the second baffle 342. The operation path is not blocked by the mounting plate 13, solving the problem of the mounting plate 13 blocking disassembly. After the user removes the first baffle 341 or the second baffle 342, the first fan 32 or the second fan 33 can be exposed in the refrigeration chamber 201. Maintenance personnel can directly remove or observe the first fan 32 and the second fan 33 through the refrigeration chamber 201, simplifying the maintenance process of the refrigeration duct 300 and improving the efficiency of the maintenance of the refrigeration duct 300.

[0058] In some embodiments, the first baffle 341 can be detachably fixed to the mounting base 31 by means of snap-fit, plug-in, or screw connection. The second baffle 342 can be detachably fixed to the mounting base 31 by means of snap-fit, plug-in, or screw connection.

[0059] Figure 6 for Figure 5 A partial schematic diagram of the cooling air duct; Figure 7 for Figure 6 An exploded image.

[0060] like Figure 6 and Figure 7 As shown, in some embodiments, the mounting base 31 may be provided with connecting posts 39, and at least two connecting posts 39 are provided. At least one connecting post 39 is provided at the first air cavity 310. Correspondingly, the first baffle 341 is provided with a first connecting hole 306. The first connecting hole 306 is arranged correspondingly to the connecting post 39 in the first air cavity 310. Then, screws are inserted into the first connecting hole 306 and the connecting post 39, so that the first baffle 341 and the mounting base 31 can be detachably connected.

[0061] At least one connecting post 39 is provided at the second air cavity 320. Correspondingly, the second baffle 342 is provided with a second connecting hole 307. The second connecting hole 307 is arranged in correspondence with the connecting post 39 in the second air cavity 320. Then, screws are inserted into the second connecting hole 307 and the connecting post 39, so that the second baffle 342 and the mounting base 31 can be detachably connected.

[0062] like Figure 7 As shown, in some embodiments, the mounting base 31 may have a partition 311 inside, which is used to divide the internal space of the mounting base 31 into a first air cavity 310 and a second air cavity 320. The partition 311 is located on the back side of the mounting plate 13. The side of the first baffle 341 near the second baffle 342 is engaged with the partition 311. The side of the second baffle 342 near the first baffle 341 is engaged with the partition 311.

[0063] By setting a partition 311 inside the mounting base 31, independent first air cavity 310 and second air cavity 320 can be formed inside the mounting base 31, reducing airflow crosstalk between the first air cavity 310 and the second air cavity 320, so that the first fan 32 and the second fan 33 can operate independently without interfering with each other.

[0064] On the other hand, the side of the first baffle 341 closest to the second baffle 342 is engaged with the partition 311. During maintenance of the first fan 32, personnel only need to press the engaged portion of the baffle to detach the first baffle 341 from the mounting base 31 at the partition 311, or manually engage the first baffle 341 with the partition 311 to securely install the first baffle 341 onto the mounting base 31. Similarly, during maintenance of the second fan 33, personnel only need to press the engaged portion of the second baffle 342 to detach the second baffle 342 from the mounting base 31 at the partition 311, or manually engage the second baffle 342 with the partition 311 to securely install the second baffle 342 onto the mounting base 31. This allows maintenance personnel to quickly disassemble the baffles without tools, and the disassembly process is not obstructed by the mounting plate 13, providing ample operating space.

[0065] In some embodiments, the partition 311 may be provided with a first slot 301 and a second slot 302, wherein the first slot 301 and the second slot 302 may be arranged vertically at intervals.

[0066] The first baffle 341 has a first buckle 35 on the side near the second baffle 342, which engages with the first slot 301. The second baffle 342 has a second buckle 36 on the side near the first baffle 341, which engages with the second slot 302.

[0067] Specifically, by providing a first buckle 35 that engages with the first slot 301 on the first baffle 341 and a second buckle 36 that engages with the second slot 302 on the second baffle 342, maintenance personnel do not need screwdrivers or other tools. They only need to reach into the partition space 101 with their hands, align the buckle positions and press them to cause the first buckle 35 or the second buckle 36 to elastically deform and disengage from the slot. This allows the first baffle 341 to be removed from the partition 311 and the second baffle 342 to be removed from the partition 311. This avoids the need to use screws at the joint between the first baffle 341 and the second baffle 342, and avoids increasing the difficulty of disassembly and installation by using tools in the narrow space of the partition space 101. This reduces the difficulty of disassembly and installation and improves the efficiency of installation and disassembly.

[0068] In some embodiments, multiple first buckles 35 may be provided, and the multiple first buckles 35 may be respectively provided on opposite sides of the first baffle 341. Multiple second buckles 36 may be provided, and the multiple second buckles 36 may be respectively provided on opposite sides of the second baffle 342.

[0069] Figure 8 for Figure 6 A schematic diagram of the first baffle.

[0070] like Figure 8 As shown, in some embodiments, the first latch 35 may include a first elastic arm 351 and a first engaging portion 362. One end of the first elastic arm 351 is connected to the side of the first baffle 341 near the second baffle 342, and the other end of the first elastic arm 351 extends toward the front side of the first baffle 341.

[0071] The first engaging portion 362 is located on the side of the first elastic arm 351 near the second baffle 342. Specifically, the first engaging portion 362 can be a protruding structure, such as a wedge-shaped, arc-shaped, or rectangular protruding rib.

[0072] The first elastic arm 351 can abut against the first slot 301, and the first engaging part 362 engages with the side wall of the first slot 301, so that the first baffle 341 is fixed on the partition 311.

[0073] Specifically, by connecting one end of the first elastic arm 351 to the side of the first baffle 341 and extending the other end forward to form a cantilever structure, the first elastic arm 351 possesses elastic deformation capability. When the first baffle 341 is installed, the first elastic arm 351 deforms under pressure, allowing the first locking part 362 to slide smoothly into the locking groove. After installation, the first elastic arm 351 returns to its original shape, enabling the first locking part 362 to form an interference fit with the side wall of the first locking groove 301, thereby ensuring a firm fixation between the first baffle 341 and the mounting base 31, preventing it from falling off even under vibration or impact.

[0074] In some embodiments, the first elastic arm 351 may be V-shaped.

[0075] like Figure 8 As shown, in some embodiments, the first elastic arm 351 may include a first extension 3511 and a first bending portion 3512. The first extension 3511 is connected to the side of the first baffle 341 near the second baffle 342 and extends toward the back side of the first baffle 341. The first bending portion 3512 extends from the rear end of the first extension 3511 toward the front side of the first baffle 341, and the first bending arm is located on the side of the first extension 3511 near the second baffle 342. The side of the first bending portion 3512 facing the second baffle 342 is provided with a first engaging portion 362. The front end of the first bending portion 3512 protrudes from the front wall of the first baffle 341 and extends into the spacer 101. Specifically, by connecting one end of the first extension 3511 to one side of the first baffle 341 and extending the other end rearward, the first extension 3511 provides elastic support for the entire first elastic arm 351. The second bending portion 3612 extends from the rear end of the first extension 3511 toward the front of the first baffle 341, which increases the deformation capacity and improves the overall structural strength of the first elastic arm 351. This allows the first latch 35 to disperse stress through the segmental deformation of the first elastic arm 351 when subjected to external force, preventing the first elastic arm 351 from breaking due to stress concentration. Moreover, maintenance personnel only need to press the front end of the bending portion protruding into the interval space 101 with their fingers to disengage the first latch 362 from the first latch groove 301 through the deformation generated by the first bending portion 3512, without the need for additional tools to disassemble and install the first baffle 341. This also reduces the difficulty for users to operate within the narrow interval space 101 formed by the back of the mounting plate 13.

[0076] Figure 9 for Figure 6 A schematic diagram of the second baffle.

[0077] like Figure 9 As shown, in some embodiments, the second latch 36 may include a second elastic arm and a second latching portion. One end of the second elastic arm is connected to the side of the second baffle 342 near the first baffle 341, and the other end of the second elastic arm extends toward the front side of the second baffle 342.

[0078] The second engaging portion is located on the side of the second elastic arm near the first baffle 341. Specifically, the second engaging portion can be a protruding structure, such as a wedge-shaped, arc-shaped, or rectangular protruding rib.

[0079] The second elastic arm can abut against the second slot 302, and the second snap-fit ​​part snaps against the side wall of the second slot 302, so that the second baffle 342 is fixed on the partition 311. Specifically, by connecting one end of the second elastic arm to the side of the second baffle 342 and extending the other end forward to form a cantilever structure, the second elastic arm possesses elastic deformation capability. When the second baffle 342 is installed, the second elastic arm deforms under pressure, allowing the second locking part to slide smoothly into the second locking groove 302. After installation, the second elastic arm returns to its original shape, allowing the second locking part to form an interference fit with the side wall of the second locking groove 302, thereby ensuring a firm fixation between the second baffle 342 and the mounting base 31, preventing it from falling off even under vibration or impact.

[0080] In some embodiments, the second elastic arm may be V-shaped.

[0081] like Figure 9 As shown, in some embodiments, the second elastic arm may include a second extension 3611 and a second bending portion 3612. The second extension 3611 is connected to the side of the second baffle 342 near the first baffle 341 and extends toward the back side of the second baffle 342. The second bending portion 3612 extends from the rear end of the second extension 3611 toward the front side of the second baffle 342, and is located on the side of the second extension 3611 near the first baffle 341. A second engaging portion is provided on the side of the second bending portion 3612 facing the first baffle 341. The front end of the second bending portion 3612 protrudes from the front wall of the second baffle 342 and extends into the spacer 101. Specifically, by connecting one end of the second extension 3611 to one side of the second baffle 342 and extending the other end rearward, the second extension 3611 can provide elastic support for the entire second elastic arm. The second bending portion 3612 extends from the rear end of the second extension 3611 toward the front side of the second baffle 342, which can increase the deformation capacity and improve the overall structural strength of the second elastic arm. This allows the second latch 36 to disperse stress through the segmental deformation of the second elastic arm when subjected to external force, preventing the second elastic arm from breaking due to stress concentration. On the other hand, maintenance personnel only need to press the front end of the bending portion protruding into the interval space 101 with their fingers to disengage the second latch from the second slot 302 through the deformation generated by the second bending portion 3612. This eliminates the need for additional tools to disassemble and install the second baffle 342, and reduces the difficulty for users to operate within the narrow interval space 101 formed by the back of the mounting plate 13.

[0082] like Figure 7As shown, in some embodiments, a first air duct wall 371 may be provided inside the first air cavity 310. The first air duct wall 371 is arranged circumferentially around the first fan 32, and the first air duct wall 371 and the side wall of the mounting base 31 form the first air cavity 310. The first air duct wall 371 is arranged circumferentially around the first fan 32 to form the first air cavity 310. An air outlet may be provided at the lower end of the first air cavity 310 so that the airflow in the first air cavity 310 can be delivered downward.

[0083] The first baffle 341 is provided with a first air intake 303. The first air intake 303 can be located on the front side wall of the first baffle 341. The first air intake 303 is arranged opposite to and connected to the first air cavity 310. The first air intake 303 connects the refrigeration chamber 201 and the first air cavity 310.

[0084] Specifically, by arranging a first air duct wall 371 around the first fan 32, the first air duct wall 371 and the side wall of the mounting base 31 together form a complete first air cavity 310, which in turn constitutes the airflow channel of the first fan 32. In this way, the first air duct wall 371 can form a channel that restricts airflow along the circumference of the first fan 32, forcing the cold air to flow only along the path guided by the air duct wall. After the airflow enters the first air cavity 310 through the first air intake 303, it flows to the cooling room 201 through the air outlet of the first air cavity 310. This can prevent airflow cross-flow between the first air cavity 310 and the second air cavity 320, and at the same time prevent the formation of vortices in the airflow inside the first air cavity 310.

[0085] Figure 10 for Figure 7 A schematic diagram of the back of the first and second baffles.

[0086] like Figure 10 As shown, in some embodiments, a first sealing wall 3411 may be provided on the side wall of the first baffle 341 facing the first air cavity 310. When the first baffle 341 is fixed on the mounting base 31, the first sealing wall 3411 is arranged on the outside of the first air duct wall 371 to seal the gap between the first air duct wall 371 and the baffle. In this way, the efficiency of the fan's air delivery can be avoided due to the assembly gap between the first air duct wall 371 and the first baffle 341, and the airflow can also be prevented from leaking outward through the assembly gap between the first air duct wall 371 and the first baffle 341.

[0087] In some embodiments, a second air duct wall 372 may be provided within the second air cavity 320. The second air duct wall 372 is arranged circumferentially around the second fan 33, and the second air duct wall 372 and the side wall of the mounting base 31 form the second air cavity 320. The second air duct wall 372 is arranged circumferentially around the second fan 33 to form the second air cavity 320. An air outlet may be provided at the lower end of the second air cavity 320, allowing the airflow within the second air cavity 320 to be delivered downwards.

[0088] The second baffle 342 is provided with a second air intake 304. The second air intake 304 can be located on the front side wall of the second baffle 342. The second air intake 304 is arranged opposite to and connected to the second air cavity 320. The second air intake 304 connects the refrigeration chamber 201 and the second air cavity 320.

[0089] Specifically, by arranging a second air duct wall 372 around the second fan 33, the second air duct wall 372 and the side wall of the mounting base 31 together form a complete second air cavity 320, thus constituting the airflow channel of the second fan 33. In this way, the second air duct wall 372 can form a channel that restricts airflow along the circumference of the second fan 33, forcing the cold air to flow only along the path guided by the air duct wall. After the airflow enters the second air cavity 320 through the second air intake 304, it flows to the cooling room 201 through the air outlet of the second air cavity 320. This can prevent airflow cross-flow between the first air cavity 310 and the second air cavity 320, and at the same time prevent the formation of vortices in the airflow inside the first air cavity 310.

[0090] like Figure 10 As shown, in some embodiments, a second sealing wall 3421 may be provided on the side wall of the second baffle 342 facing the second air cavity 320. When the second baffle 342 is fixed on the mounting base 31, the second sealing wall 3421 is arranged on the outside of the second air duct wall 372 to seal the gap between the second air duct wall 372 and the baffle. In this way, the efficiency of the fan's air delivery can be avoided due to the assembly gap between the second air duct wall 372 and the second baffle 342, and the airflow can also be prevented from leaking outward through the assembly gap between the second air duct wall 372 and the second baffle 342.

[0091] like Figure 4 As shown, in some embodiments, mounting plates 13 are spaced apart on the front side of the rear wall inside the box liner 2, with the upper end of the mounting plate 13 connected to the top wall of the box liner 2 and the lower end of the box liner 2 connected to the bottom wall of the box liner 2.

[0092] Specifically, support members can be provided on both sides of the mounting plate 13, and the rear side of the shelf 12 can be supported on the mounting plate 13 by the support members. By connecting the upper and lower ends of the mounting plate 13 to the bottom wall and the top wall of the cabinet 2 respectively, the upper end of the mounting plate 13 can extend to the top of the refrigeration compartment 201, and the lower end of the mounting plate 13 can extend to the bottom of the refrigeration compartment 201, thereby supporting the multiple shelves 12 of the refrigeration compartment 201 in various height directions.

[0093] Since the mounting plates 13 are spaced apart on the front side of the rear wall inside the liner 2, the space 101 between the mounting plates 13 and the rear wall can be used to arrange the heat exchanger pipes, drain pipes 41 and other structures, without taking up extra space inside the liner 2, and can also improve the aesthetics of the interior of the refrigeration chamber 201.

[0094] like Figure 3 and Figure 4 As shown, in some embodiments, the cooling duct 300 may include a lower baffle 38, which is disposed on the back of the casing 2 and located at the lower end of the mounting base 31. The lower baffle 38 and the back of the casing 2 enclose a heat exchange cavity 330. The first air cavity 310 and the second air cavity 320 are respectively connected. The refrigeration unit also includes an evaporator 14, which is located inside the heat exchange chamber 330; The refrigeration device also includes a water receiving component 4, which is fixed to the inner side of the lower baffle 38 and located in the heat exchange chamber 330. The water receiving component 4 is arranged at the lower end of the evaporator 14 and is used to receive the condensate in the heat exchange chamber 330.

[0095] Specifically, the lower baffle 38 and the rear wall of the box liner 2 enclose a heat exchange cavity 330. The lower ends of the first air cavity 310 and the second air cavity 320 are connected to the heat exchange cavity 330, so that the airflow in the first air cavity 310 and the second air cavity 320 can flow into the heat exchange cavity 330 respectively, and be delivered to the refrigeration chamber 201 through the air outlet on the lower baffle 38.

[0096] By setting an evaporator 14 in the heat exchange chamber 330, the evaporator 14 can serve as a common heat exchange element for the first air chamber 310 and the second air chamber 320. This eliminates the need for a separate evaporator 14 in each air chamber, effectively ensuring a stable and consistent supply of cold air to both sides of the refrigeration chamber 201. This is beneficial for achieving temperature uniformity at different locations within the refrigeration chamber 201 and avoids the problems of complex structure and inconsistent temperature on both sides of the refrigeration chamber 201 caused by dual evaporators 14.

[0097] like Figure 4 As shown, in some embodiments, the return gas end of the evaporator 14 is provided with a first connecting pipe 141, and the liquid inlet end of the evaporator 14 is provided with a second connecting pipe 142. The first connecting pipe 141 and the second connecting pipe 142 can be arranged on the same side of the evaporator 14. The first connecting pipe 141 and the second connecting pipe 142 can be arranged downward along the heat exchange chamber 330 respectively, and bend towards the side where the mounting plate 13 is located, and then extend downward through the space on the back of the mounting plate 13.

[0098] In some embodiments, the water receiving component 4 can be snapped into the lower baffle 38, which can simplify the fixing of the water receiving component 4.

[0099] In some embodiments, the water receiving component 4 may be provided with a first support arm 42 on the side near the evaporator 14, and an end plate on the side of the evaporator 14 may be supported on the upper end of the first support arm 42. The water receiving component 4 may be provided with a second support arm 43 on the other side near the evaporator 14, and an end plate on the other side of the evaporator 14 may be supported on the upper end of the second support arm 43.

[0100] The water receiving part 4 is provided with a first support arm 42 and a second support arm 43 on both sides. The first support arm 42 and the second support arm 43 can support the two ends of the evaporator 14 respectively, so that the force on the evaporator 14 can be evenly distributed to the first support arm and the second support arm.

[0101] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of this application is limited only by the appended claims.
