Detailed Implementation

[0048] The embodiments of this application are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0049] The refrigeration apparatus according to an embodiment of the present application is described below with reference to Figures 1-17.

[0050] Please refer to Figure 1. The refrigeration equipment 1000 provided in this embodiment of the application includes a cabinet 100, a door and a partition assembly 300.

[0051] The refrigeration equipment 1000 provided in this application embodiment can be a sideboard, refrigerator, freezer, or wine cabinet, etc., and is not specifically limited.

[0052] The housing 100 is equipped with a first cooling chamber 120a.

[0053] The cabinet 100 includes an outer shell, an inner liner 110 inside the outer shell, and an insulation layer between the outer shell and the inner liner 110. The outer shell can be made of metal (such as steel plate), with a painted surface to prevent rust and for aesthetic purposes. The insulation layer, located between the inner side of the outer shell and the inner liner 110, can be polyurethane foam, providing good thermal insulation performance and effectively preventing heat exchange between the inside and outside, maintaining a stable internal temperature. The inner liner 110 is the part that directly contacts the stored items and is generally made of ABS plastic or stainless steel, requiring non-toxicity and easy cleaning. The interior of the inner liner 110 forms a first cooling chamber 120a for accommodating the stored items.

[0054] The door also comprises a three-layer structure: an outer shell, insulation material, and an inner lining, ensuring good sealing and insulation performance. The door is connected to the housing 100 via a hinge structure, allowing for free opening and closing. The door can be a single door or a double door; a single door can also have the function of reversing the opening direction. A sealing strip can be installed at the edge of the door, fitting tightly against the housing 100 to prevent cold air leakage and sealing the first refrigeration chamber 120a in conjunction with the housing 100. Taking the side with the door as the front side as an example, the depth direction of the first refrigeration chamber 120a is from front to back.

[0055] Please refer to Figures 1, 2 and 3. The partition assembly 300 is disposed in the first refrigeration chamber 120a and arranged along the depth direction of the first refrigeration chamber 120a. The partition assembly 300 is provided with an air supply pipe 311 communicating with the first refrigeration chamber 120a.

[0056] The partition assembly 300 is provided with an air supply duct 311 communicating with the first refrigeration chamber 120a, which can deliver cold air into the first refrigeration chamber 120a. By arranging the partition assembly 300 along the depth direction of the first refrigeration chamber 120a, the partition assembly 300 and the air supply duct 311 therein are arranged on the side of the first refrigeration chamber 120a in the width direction, thereby reducing the occupancy of the partition assembly 300 in the depth direction of the first refrigeration chamber 120a. When the depth of the refrigeration chamber 120 is the same, this arrangement method allows the overall thickness of the refrigeration equipment 1000 to be thinner compared with the traditional refrigeration equipment 1000 which arranges the air supply duct 311 on one side of the depth direction of the refrigeration chamber 120, thus improving aesthetics and practicality.

[0057] Please refer to Figures 1, 2 and 3. The integrated air supply and return housing 400 is located on one side of the first refrigeration chamber 120a and connected to the partition assembly 300. The integrated air supply and return housing 400 is provided with an air supply channel 411 and a return air channel 421 distributed along the depth direction of the first refrigeration chamber 120a. The air supply channel 411 is connected to the air supply pipe 311, and the return air channel 421 is connected to the refrigeration chamber 120.

[0058] Please refer to Figure 10. The integrated air supply and return housing 400 integrates both an air supply channel 411 and a return air channel 421. The integrated air supply and return housing 400 delivers and recovers cold air to the first refrigeration chamber 120a, thereby realizing the circulation of cold air in the first refrigeration chamber 120a.

[0059] The integrated air supply and return housing 400 is located on one side of the first refrigeration chamber 120a and connected to the partition assembly 300, so that the air supply channel 411 of the integrated air supply and return housing 400 is connected to the air supply pipe 311. Cold air is delivered to the air supply pipe 311 through the air supply channel 411, and then delivered to the first refrigeration chamber 120a through the air supply pipe 311, thereby achieving the cooling of the first refrigeration chamber 120a. The return air channel 421 is connected to the refrigeration chamber 120, and the cold air in the refrigeration chamber 120 can be recovered to the evaporator 530 for cooling through the return air channel 421, and then delivered out through the air supply channel 411, forming a circulation of cold air within the refrigeration equipment 1000.

[0060] The air supply duct 411 and return duct 421 of the integrated air supply and return housing 400 are also distributed along the depth direction of the first refrigeration chamber 120a and connected to the partition assembly 300. Therefore, the integrated air supply and return housing 400 has minimal impact on the thickness of the refrigeration equipment 1000, and also has minimal impact on the width and depth of the internal refrigeration chamber 120, thus improving the internal space utilization of the refrigeration equipment 1000. Furthermore, the integrated air supply and return housing 400 simplifies the air duct system structure within the refrigeration equipment 1000, reduces space occupation, facilitates assembly, and greatly improves assembly efficiency and accuracy.

[0061] According to the refrigeration equipment 1000 provided in the embodiments of this application, by arranging the partition assembly 300 and the integrated air supply and return structure along the depth direction of the first refrigeration cavity 120a, the impact on the thickness of the refrigeration equipment 1000 is reduced, allowing the refrigeration equipment 1000 to be made thinner. At the same time, by setting the integrated air supply and return shell 400, the air supply and return structure is integrally formed, reducing the number of parts and the space occupied by the entire part, thereby reducing the occupation of the effective volume of the refrigeration cavity 120, improving space utilization, simplifying the assembly process, and improving assembly efficiency.

[0062] Please refer to Figures 3 to 6. According to some embodiments of this application, the door is installed over the opening of the first cooling chamber 120a, and the return air channel 421 is located on the side of the supply air channel 411 near the door.

[0063] The door is installed over the opening of the first refrigeration chamber 120a to cooperate with the housing 100 to seal the first refrigeration chamber 120a. The return air channel 421 is located on the side of the air supply channel 411 near the door, that is, the return air inlet 313 in the first refrigeration chamber 120a is located on the side near the opening of the first refrigeration chamber 120a.

[0064] By placing the return air duct 421 on the side closer to the door, when the door is opened, warm outside air enters the first cooling chamber 120a. The side of the return air duct 421 closer to the door can quickly draw in and cool this warm air, reducing temperature fluctuations and maintaining a stable temperature inside the chamber. Because the return air duct 421 can quickly expel the incoming warm air, the compressor's operating time is shortened, thereby reducing energy consumption and improving energy efficiency. The side of the return air duct 421 closer to the door can more effectively expel moisture from the door seams, reducing condensation and keeping the refrigerator interior dry. Furthermore, the position of the return air vent 313 does not affect the user's ability to retrieve food, as most users are accustomed to taking items from the side closer to the door. The air supply duct 411 is located on the side farther from the door, preventing cold air from blowing directly on the user when opening the door. This design is more user-friendly and improves the user experience.

[0065] Furthermore, it solves the problem of numerous online assembly processes for refrigeration components and air ducts in existing products, reducing assembly difficulty, labor costs, and improving assembly efficiency. In addition, it makes full use of the unused space inside the refrigerator, thereby increasing the internal volume of the first refrigeration chamber 120a and the second refrigeration chamber 120b, achieving large-space storage for the refrigeration equipment 1000.

[0066] Please refer to Figures 3 to 6. According to some embodiments of this application, the housing 100 may also be provided with a second cooling chamber 120b distributed along the height direction with the first cooling chamber 120a. The second cooling chamber 120b may be provided with an air duct module 500. The integrated air supply and return shell 400 may be disposed between the first cooling chamber 120a and the second cooling chamber 120b, and may be connected between the air duct module 500 and the partition assembly 300.

[0067] Taking a vertical sideboard as an example, the refrigeration unit 1000 can include a first refrigeration chamber 120a located on the upper side and a second refrigeration chamber 120b located on the lower side. By setting up the first refrigeration chamber 120a and the second refrigeration chamber 120b, storage zones with multiple temperatures can be achieved. According to the conventional design of the refrigeration unit 1000, the first refrigeration chamber 120a can be a refrigerator compartment with a relatively high temperature, used to store items requiring refrigeration and preservation; the second refrigeration chamber 120b can be a freezer compartment with a relatively low temperature, used to store items requiring long-term freezing. It is understood that when multiple refrigeration chambers 120 are provided, the inner liner 110 has multiple corresponding refrigeration chambers 120.

[0068] The air duct module 500 can recover hot air and output cold air. The integrated air supply and return housing 400 is set between the air duct module 500 and the partition assembly 300, so that the cold air output by the air duct module 500 can enter the air supply pipe 311 through the air supply channel 411 and then be transported to the first cooling chamber 120a. The return air channel 421 can be connected to the air duct module 500 to recover the hot air in the first cooling chamber 120a back to the air duct module 500 through the return air channel 421.

[0069] It should be noted that the air duct module 500 also extends along the depth direction of the second refrigeration chamber 120b, so that the air duct module 500, the integrated air supply and return housing 400 and the partition assembly 300 are aligned in the height direction, thereby reducing the impact on the thickness of the refrigeration equipment 1000 and the effective volume of the first refrigeration chamber 120a and the second refrigeration chamber 120b, and improving the overall refrigeration effect and space utilization.

[0070] Please refer to Figure 3. According to some embodiments of this application, the air duct module 500 may be provided with an air supply cavity 510 and a return air duct 540. The air supply cavity 510 may be provided with a fan 520 and an evaporator 530. The two ends of the air supply channel 411 in the height direction are respectively connected to the air supply duct 311 and the air supply cavity 510. The two ends of the return air channel 421 are respectively connected to the return air duct 540 and the first refrigeration cavity 120a.

[0071] The fan 520 is used to drive cold air to circulate in the refrigeration chamber 120 and the shell to improve refrigeration efficiency. The evaporator 530 is used to absorb heat to achieve the refrigeration effect. The fan 520 and the evaporator 530 can be fixed in the air supply chamber 510 by the bracket to ensure their stability and reliability.

[0072] The upper end of the air supply duct 411 is connected to the air supply pipe 311, and the lower end is connected to the air supply cavity 510, so that when the fan 520 in the air supply cavity 510 is working, the cold air in the air supply cavity 510 can be transported to the air supply duct 411. The upper end of the return air duct 421 is connected to the first cooling cavity 120a, and the lower end is connected to the return air pipe 540, so that the hot air in the first cooling cavity 120a can enter the return air pipe 540 through the return air duct 421, and then be connected to the air supply cavity 510 through the return air pipe 540.

[0073] The fan 520 is installed at the upper end of the air supply chamber 510 so that the fan 520 is close to the integrated air supply and return housing 400. The upper air outlet of the fan 520 is directly connected to the air supply channel 411 to shorten the air outlet path and improve the air outlet efficiency.

[0074] Please refer to Figures 7 and 8. According to some embodiments of this application, the partition assembly 300 may be disposed in the middle of the first cooling chamber 120a in the width direction to divide the first cooling chamber 120a into two chambers, and the air duct module 500 may be disposed in the middle of the second cooling chamber 120b in the width direction.

[0075] By placing the partition assembly 300 in the middle of the first refrigeration chamber 120a in the width direction and placing the air duct module 500 in the middle of the second refrigeration chamber 120b in the width direction, the refrigeration device 1000 is made into a vertically centrally located system, and the air duct system of the refrigeration device 1000 is arranged in the middle of the refrigeration device 1000, thus dividing the first refrigeration chamber 120a and the second refrigeration chamber 120b into two chambers.

[0076] From a temperature control perspective, different chambers can be set to different temperatures to meet the storage needs of different types of food. Furthermore, each chamber can have its own corresponding door, allowing for independent temperature control of each chamber. This reduces the impact of opening doors on the temperatures of other chambers, maintaining a stable storage environment. Independent temperature control for each chamber reduces unnecessary cooling waste, improves overall energy efficiency, and smaller chambers cool more quickly than larger ones, reducing compressor operating time and energy consumption.

[0077] From a space utilization perspective, the shelf assembly 300 can be adjusted according to actual needs, allowing users to flexibly allocate storage space based on the size and quantity of food. Different types of stored items can be stored separately to avoid cross-contamination and maintain freshness and hygiene. Users can also quickly find the items they need based on their type, improving retrieval convenience, reducing door opening time, and further minimizing cold air loss. Different compartments can effectively isolate odors between food items, keeping the air inside the refrigerator fresh.

[0078] Please refer to Figures 3 and 6. According to some embodiments of this application, the partition assembly 300 may be provided with air supply pipes 311 that communicate with two chambers respectively, and the integrated air supply and return housing 400 is provided with two air supply channels 411 that communicate with the two air supply pipes 311 respectively. The two air supply channels 411 and the return air channel 421 are arranged along the depth direction of the first cooling chamber 120a, and the return air channel 421 communicates with the two chambers respectively.

[0079] By setting two air supply pipes 311 in the partition assembly 300, the two air supply pipes 311 are respectively used to supply air to the two chambers of the first cooling chamber 120a, which facilitates precise air supply to the two chambers. The integrated air supply and return housing 400 is provided with two air supply channels 411 that correspond one-to-one with the two air supply pipes 311. Air is supplied to the corresponding air supply pipes 311 through the corresponding air supply channels 411, thereby improving the temperature control accuracy.

[0080] The return air duct 421 can connect to two chambers simultaneously, so that the hot air from both chambers can be returned to the air duct module 500 through the return air duct 421. The return air efficiency is high. Using a return air duct 421 can simplify the internal design of the refrigeration equipment 1000, reduce the number of required pipes and components, thereby saving space and improving space utilization and assembly efficiency.

[0081] Furthermore, the single return air structure saves space compared to other components, allowing for a larger return air duct 421. This reduces airflow resistance, improves cold air circulation efficiency, and consequently reduces compressor operating time and energy consumption. It also reduces airflow noise, enhancing the user's quiet experience when using the refrigerator. Reducing potential points of failure and improving system reliability and stability, the single return air structure makes fault location and repair easier in case of malfunction, reducing maintenance time and costs.

[0082] Among them, the two air supply channels 411 and the return air channel 421 are arranged along the depth direction of the first refrigeration chamber 120a, and the corresponding two air supply pipes 311 are also arranged along the depth direction of the first refrigeration chamber 120a, so as to reduce the occupation of the integrated air supply and return air shell 400 and the partition assembly 300 in the width direction of the refrigeration equipment 1000, improve the space utilization rate, and facilitate the corresponding connection between the air supply channel 411 and the air supply pipe 311.

[0083] Please refer to Figures 8 and 9. According to some embodiments of this application, the partition assembly 300 may include two partitions 310 spaced apart along the distribution direction of the two chambers. Each partition 310 is provided with an air supply port and a return air port 313. The partition assembly 300 is provided with a connecting cavity 312 that communicates with the return air ports 313 on the two partitions 310. The return air passage 421 communicates with the connecting cavity 312.

[0084] Two partitions 310 can be spaced apart along the distribution direction of the chambers to facilitate the placement of air supply ducts 311 and insulation material between the two partitions 310. By placing insulation material within the partition assembly 300, temperature transfer between the two chambers is isolated, thereby improving the cooling effect. Each partition 310 has an air outlet communicating with the air supply duct 311. The two air supply ducts 311 are respectively connected to the air outlets on the two partitions 310, allowing the two air supply ducts 311 to supply air to the two chambers respectively.

[0085] The partition 310 may also be provided with a return air vent 313, which is used for the return air of the corresponding chamber. A connecting cavity 312 is provided between the two partitions 310, communicating with the two return air vents 313. Specifically, the two return air vents 313 are arranged opposite each other to reduce the space occupied by the connecting cavity 312. The connecting cavity 312 can be located at the lower end of the partition assembly 300 so that it can communicate with the return air channel 421. Hot air from the two chambers flows through the return air vents 313 into the connecting cavity 312, and then enters the return air channel 421 from the connecting cavity 312, thus achieving the return air of the two chambers. Furthermore, because the return air vents 313 are located on the partition 310, that is, arranged along the height direction, the risk of items falling into the return air vents 313 is reduced, improving ease of use.

[0086] Please refer to Figures 4 and 5. According to some embodiments of this application, at least one of the two partitions 310 includes a maintenance plate 314. The maintenance plate 314 is disposed at the end where the partition assembly 300 is connected to the return air housing 420, and the return air inlet 313 is disposed on the maintenance plate 314.

[0087] At least one of the two partitions 310 may include an inspection plate 314 and a plate body. The plate body is fixedly connected to the inner liner 110 of the housing 100, and the inspection plate 314 is detachably installed on the plate body. The inspection plate 314 is located at the end where the partition assembly 300 connects to the return air housing 420, that is, at the end where the partition assembly 300 connects to the supply air housing 410. By disassembling the inspection plate 314, the return air housing 420, the supply air housing 410, and the dampers 412 and drive components 413 inside the supply air housing 410 can be inspected and maintained, thereby improving maintenance efficiency and reducing maintenance costs.

[0088] The return air inlet 313 of the partition 310 on the side with the inspection plate 314 can be set on the inspection plate 314, so that after the inspection plate 314 is opened, it is convenient to inspect and maintain the connecting cavity 312 and the return air shell 420.

[0089] Please refer to Figures 8 and 9. According to some embodiments of this application, the partition assembly 300 can be connected to both ends of the first cooling cavity 120a in the height direction, the connecting cavity 312 can be located at one end of the partition assembly 300 in the height direction, and the projection of the return air channel 421 in the height direction can be located in the connecting cavity 312.

[0090] The partition assembly 300 is connected to both ends of the first cooling chamber 120a in the height direction. The partition assembly 300 is also connected to the rear wall of the first cooling chamber 120a in the depth direction, which can provide better structural support, increase the stability of the partition assembly 300, and reduce deformation or displacement caused by vibration or external force.

[0091] The connecting cavity 312 is located at one end of the partition assembly 300 in the height direction to provide a better gas circulation path and improve the cooling effect of the cold air circulation. At the same time, placing the connecting cavity 312 at the end can reduce the space occupied by the connecting cavity 312 and ensure the heat insulation performance of the partition assembly 300. Specifically, due to the principle of cold air sinking, the connecting cavity 312 can be located at the lower end of the partition assembly 300, and the return air shell 420 is also located at the lower end of the first cooling cavity 120a to connect with the connecting cavity 312.

[0092] The projection of the return air duct 421 in the height direction is located within the connecting cavity 312, that is, the projection of the return air duct 421 in the height direction is located within the partition assembly 300, thereby controlling the size of the return air duct 421 and the return air shell 420. While ensuring the return air effect, the size of the components is reduced, the space utilization rate is improved, the production cost is reduced, and the economic benefits are improved.

[0093] Please refer to Figure 9. According to some embodiments of this application, a baffle 315 may be provided in the communicating cavity 312, and the baffle 315 may be disposed between two return air vents 313.

[0094] The baffle 315 extends along the height and depth of the cooling cavity 120, and is located at the center of the baffle 315 assembly in the thickness direction, thus blocking the airflow between the two return air vents 313. The baffle 315 prevents direct flow of cold or warm air between the two return air vents 313, avoiding airflow short-circuiting and ensuring more even distribution of cold or warm air in each cavity. The baffle 315 guides airflow along a predetermined path, ensuring each cavity receives sufficient cold or warm air, improving airflow circulation efficiency, and facilitating more precise temperature control in each cavity, thus improving temperature control accuracy. The baffle 315 also reduces airflow turbulence within the connecting cavity 312, lowering noise generated during airflow and enhancing the quieter user experience when using the refrigerator.

[0095] Please refer to Figures 11 to 14. According to some embodiments of this application, the wall of the chamber near the integrated air supply and return housing 400 may be provided with a return air inlet 313, and the return air channel 421 may have two air inlets 4211 respectively connected to the return air inlets 313 of the two chambers.

[0096] First, it should be noted that the inner liner 110 of the first cooling chamber 120a in Figures 11 and 12 is not shown. You can refer to Figure 1 to determine the location of the return air vent 313.

[0097] The chamber is located near the wall of the integrated air supply and return housing 400, that is, the bottom wall of the chamber is provided with a return air inlet 313, which has a good return air effect and high return air efficiency. The two return air inlets 313 are respectively located on both sides of the partition assembly 300. By setting the return air channel 421 as having two air inlet ends 4211 that communicate with the return air inlets 313 of the two chambers, the hot air from both chambers can enter the return air channel 421.

[0098] The return air duct 421 may have an air outlet 4212 so that the air outlet 4212 of the return air duct 421 can be connected to the return air pipe 540. Both air inlets 4211 of the return air duct 421 are connected to the air outlet 4212 so that the return air duct 421 is Y-shaped, which has a simple structure and can realize the return air of two chambers at the same time.

[0099] This layout optimizes the airflow path, allowing cold air to quickly cover every corner of the first cooling chamber 120a, improving the cooling effect and food preservation performance. At the same time, this structure also helps to reduce the loss of cold air and improve the energy efficiency of the refrigeration equipment 1000.

[0100] Please refer to Figures 15 and 16. According to some embodiments of this application, the integrated air supply and return housing 400 may include an air supply housing 410 with an air supply channel 411 and a return housing 420 with a return air channel 421. The air supply housing 410 extends along the depth direction of the first cooling chamber 120a, and the return housing 420 extends along the direction in which the two chambers are distributed.

[0101] The integrated air supply and return housing 400 is composed of an air supply housing 410 and a return air housing 420. The air supply housing 410 is provided with an air supply channel 411, and the return air housing 420 is provided with a return air channel 421, so that the air supply channel 411 and the return air channel 421 are spaced apart from each other. The upper end of the air supply housing 410 is connected to the upper end of the return air housing 420 as a whole, and the lower end of the air supply housing 410 is connected to the lower end of the return air housing 420 as a whole, so that the upper and lower end surfaces of the integrated air supply and return housing 400 are relatively flat, which facilitates connection with the inner liner 110 on the upper and lower sides, as well as the partition assembly 300 and the air duct module 500 located in the two inner liner 110.

[0102] The air supply housing 410 extends along the depth direction to facilitate the arrangement of the two air supply channels 411; the return air housing 420 extends along the distribution direction of the two partitions 310 so that the two air inlets 4211 of the return air inlet 313 can communicate with the return air inlets 313 located on both sides of the partition assembly 300; the integrated air supply and return housing 400 is T-shaped, with a simple structure that is easy to manufacture and assemble, improving assembly and production efficiency and reducing production costs.

[0103] Please refer to Figures 15, 16 and 17. According to some embodiments of this application, the integrated air supply and return housing 400 may be provided with an installation component 414. The installation component 414 may be provided with two air supply channels 411. The installation component 414 may be equipped with two dampers 412 that are movably disposed in the two air supply channels 411 and a drive component 413 that is dynamically coupled to the two dampers 412.

[0104] By setting up the mounting component 414, it is possible to install dampers 412 within the integrated supply and return air housing 400. Since the integrated supply and return air housing 400 has multiple air supply channels 411, it also requires multiple dampers 412. Installing multiple dampers 412 and the drive component 413 within the integrally formed integrated supply and return air housing 400 would be difficult. By setting up the mounting component 414, which includes two air supply channels 411, dampers 412, and the drive component 413, and then connecting the mounting component 414 to the air supply housing 410, the installation of the air supply channels 411 and dampers 412 can be completed. This simplifies assembly, increases efficiency, reduces development costs, and improves production efficiency.

[0105] Please refer to Figures 18 and 19, which illustrate two different configurations of the odor purifier 330 and the odor-purifying air duct 340. According to some embodiments of this application, the partition assembly 300 may contain an odor purifier 330 and an odor-purifying air duct 340. The inlet of the odor purifier 330 may communicate with the odor-purifying air duct 340, and the outlet of the odor purifier 330 may communicate with the return air duct 421. The odor-purifying air duct 340 may communicate with the first cooling chamber 120a.

[0106] The partition assembly 300 may be provided with a deodorizing air duct 340 communicating with the first refrigeration chamber 120a. A deodorizer mounting position 320 for fixing the deodorizer 330 may also be provided between the two partitions 310. The deodorizer 330 is fixed in the deodorizer mounting position 320, and the inlet of the deodorizer 330 is correspondingly connected to the deodorizing air duct 340. Air in the first refrigeration chamber 120a can enter the deodorizer 330 through the deodorizing air duct 340 to remove odors, and then exit through the outlet of the deodorizer 330, thereby achieving the function of removing odors. By connecting the outlet of the deodorizer 330 to the return air duct 421, the circulation efficiency of the gas in the first refrigeration chamber 120a is improved, enhancing the deodorizing effect.

[0107] In one example, the odor purifier 330 can be a self-powered odor purifier 330. The odor purifier 330 may be equipped with a small impeller. When the odor purifier 330 is working, it actively absorbs the gas in the first cooling chamber 120a through the odor purifying air duct 340, which has a good odor purifying effect and improves the odor purifying efficiency.

[0108] In another example, the odor purifier 330 can be a passive odor purifier 330. By connecting the return air channel 421 to the outlet of the odor purifier 330 and the inlet of the odor purifier 330 to the odor purifying air duct 340, the negative pressure of the return air channel 421 drives some of the air in the first refrigeration chamber 120a to be recovered to the return air channel 421 through the odor purifying air duct 340. After entering the odor purifying air duct 340, the air passes through the odor purifier 330 to achieve the function of odor purification. The structure is simple, the cost is low, and the stability of use is high.

[0109] In the case where the first cooling chamber 120a comprises two chambers spaced apart:

[0110] In one example, as shown in Figure 18, the odor-removing air duct 340 can be provided with one type, and each of the two partitions 310 has an air inlet 341 communicating with the odor-removing air duct 340, which simplifies the air duct structure and improves space utilization. It should be noted that only the air inlet 341 of one partition 310 is shown in Figure 18. The air inlet 341 of the other partition 310 corresponds to the position of the air inlet 341 shown in the figure, and can be determined based on the width of the odor-removing air duct 340 and the inlet width of the odor remover 330.

[0111] In another example, as shown in Figure 19, two odor-removing air ducts 340 can be provided. Each odor-removing air duct 340 is connected to one of the two chambers. Two partitions 310 are each provided with an air inlet 341 corresponding to one of the two odor-removing air ducts 340. By providing two odor-removing air ducts 340, the odor removal efficiency can be improved, and the risk of odor cross-contamination between the two chambers can be reduced. It should be noted that the odor remover 330 and the odor-removing air ducts 340 are not shown in Figure 19. The position of the odor-removing air duct 340 can be determined based on the position of the air inlet 341, and the width of the odor-removing air duct 340 can be determined based on the width of the air inlet 341. As can be seen from Figure 19, the width of the air inlet 341 is less than half the width of the inlet of the lower odor remover 330. Therefore, the other odor-removing air duct 340 is located in front of the air inlet 341 shown in the figure, and the air inlet 341 on the other partition 310 is also located in front of the air inlet 341 shown in the figure.

[0112] Specifically, the two odor-removing air ducts 340 can be distributed along the depth direction of the first cooling cavity 120a, and the inlet of the odor remover 330 can extend along the depth direction of the first cooling cavity 120a to connect with the two odor-removing air ducts 340. This arrangement can reduce the impact of the odor remover 330 and the odor-removing air ducts 340 on the thickness of the partition assembly 300 and improve space utilization.

[0113] Please refer to Figures 18 and 19. According to some embodiments of this application, the end of the partition assembly 300 connected to the integrated air supply and return housing 400 may be provided with a connecting cavity 312 that communicates with the first refrigeration cavity 120a. The connecting cavity 312 may be connected to the return air channel 421, and the outlet of the deodorizer 330 may be located in the connecting cavity 312.

[0114] The connecting cavity 312 is located on one side near the return air duct 421 to communicate with the return air duct 421. For details, please refer to the aforementioned embodiment, which will not be repeated here.

[0115] At least a portion of the odor purifier 330 may be located within the connecting cavity 312. Specifically, the outlet of the odor purifier 330 may be located within the connecting cavity 312, thereby arranging the odor purifier 330 close to the return air duct 421, thus optimizing the spatial layout and reducing the space occupied by the air duct.

[0116] Furthermore, in some embodiments, the partition 310 also includes a maintenance plate 314, with the return air vent 313 located on the maintenance plate 314, so that the maintenance plate 314 is directly opposite the connecting cavity 312. After opening the maintenance plate 314, the odor purifier 330 can be inspected and maintained at the same time, improving the convenience of inspection and maintenance, increasing maintenance efficiency, and reducing maintenance costs.

[0117] According to some embodiments of this application, the thickness W of the refrigeration device 1000 in the depth direction of the first refrigeration cavity 120a can satisfy: 450mm≤W≤600mm.

[0118] The refrigeration equipment 1000 is relatively thin, which improves its aesthetics and allows it to better fit the user's interior decoration, thus enhancing product quality. Specifically, the thickness W of the refrigeration equipment 1000 in the depth direction of the first refrigeration chamber 120a ranges from [450mm to 600mm]. For example, W can be 450mm, 500mm, 550mm, 600mm, or other values ​​between 450mm and 600mm; no specific limitation is imposed.

[0119] According to some embodiments of this application, the thickness S of the door body can satisfy: 25mm≤S≤40mm.

[0120] The door of the refrigeration unit 1000 is relatively thin, making it lightweight and easy to open. This also reduces the impact on the overall thickness of the refrigeration unit 1000, allowing it to be made thinner for better integration with the user's interior decoration and improved product quality. The door thickness S ranges from [25mm, 50mm]. For example, S can be 25mm, 30mm, 35mm, 40mm, or other values ​​between 25mm and 40mm; no specific limitation is imposed.
