[0044] 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.

[0045] The following is for reference. Figures 1-12 This application describes a refrigeration device according to an embodiment of the present application.

[0046] Please see Figure 1 and Figure 2 The refrigeration equipment 1000 provided in this application embodiment includes a cabinet 100 and a door 200.

[0047] The housing 100 has a cooling chamber 120 inside, and the door 200 is movably installed on the housing 100 for opening and closing the cooling chamber 120.

[0048] The refrigeration equipment 1000 provided in this application embodiment can be a sideboard, refrigerator, freezer, or wine cabinet, etc., and is not specifically limited.

[0049] 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 cooling cavity 120 for accommodating the stored items.

[0050] The door body 200 is movably installed on the cabinet 100 to open and close the refrigeration cavity 120, facilitating users to take and store articles. The door body 200 also comprises a three-layer structure of an outer shell, a thermal insulation material and an inner liner, ensuring good sealing and thermal insulation effects. The door body 200 can be connected with the cabinet 100 through a hinge structure, allowing the door to open and close freely. The door body 200 can be a single-door or a double-door, and the single-door can have a function of adjusting the opening direction leftward or rightward. A sealing strip can be installed at the edge of the door body 200, which is tightly attached to the cabinet 100 to prevent cold air leakage and seal the refrigeration cavity 120 together with the cabinet 100. Taking the side provided with the door body 200 as the front side as an example, the depth direction of the refrigeration cavity 120 is from the front to the back.

[0051] Referring to Figure 1 and Figure 2 , wherein, in the case that the door body 200 is in a closed state, the width M, the thickness W and the height H of the refrigeration equipment 1000 satisfy: 830mm≤M≤990mm, 435mm≤W≤500mm, 1700mm≤H≤2100mm.

[0052] As can be seen from the above parameters, the overall width and height of the refrigeration equipment 1000 are relatively large to ensure that the refrigeration equipment 1000 has sufficient storage space, and the overall thickness of the refrigeration equipment 1000 is relatively small, which is the size of the refrigeration equipment 1000 in the depth direction of the refrigeration cavity 120. The width-thickness ratio of the refrigeration equipment 1000 is almost 2:1 compared with the width, so that the refrigeration equipment 1000 is in an ultra-thin shape, meeting the storage space while being thinner.

[0053] Therefore, when used in a family, the ultra-thin refrigerator occupies less space, especially suitable for kitchens of small and medium-sized houses, which can save kitchen space; the door body 200 of the refrigeration equipment 1000 is closer to the wall, and when embeddedly installed, it can be flush with the cabinet, better matching the dining cabinet, cabinet and other furniture in home decoration, without affecting the aesthetics, making the whole kitchen look more tidy and coordinated. Greatly improving the practicability and aesthetics.

[0054] , wherein the width M of the refrigeration equipment 1000 is in the range of [830mm, 990mm], and exemplarily, the width M of the refrigeration equipment 1000 can be 830mm, 850mm, 900mm, 950mm, 990mm or other values between 830mm and 990mm, which is not limited here.

[0055] The thickness W of the refrigeration equipment 1000 is [435mm, 500mm]. For example, the thickness W of the refrigeration equipment 1000 can be 435mm, 450mm, 465mm, 480mm, 500mm or other values between 435mm and 500mm, which is not limited here.

[0056] The height H of the refrigeration equipment 1000 is [1700mm, 2100mm]. For example, the width W of the refrigeration equipment 1000 can be 1700mm, 180mm, 1900mm, 2000mm, 2100mm or other values between 1700mm and 2100mm, which is not limited here.

[0057] According to the refrigeration equipment 1000 provided by the embodiment of the present application, by limiting the height of the refrigeration equipment 1000, it is ensured that the refrigeration equipment 1000 has sufficient storage space. By limiting the thickness of the refrigeration equipment 1000, the refrigeration equipment 1000 is relatively thin as a whole, and the end surface of the refrigeration equipment 1000 is not easy to protrude from the furniture decoration such as the cabinet and the storage cabinet when used in the family, which can better cooperate with the furniture decoration. It has small indoor space occupation, improves the overall aesthetic and practicality.

[0058] Please refer to Figure 1 and Figure 2 According to some embodiments of the present application, the refrigeration cavity 120 can include a refrigeration cavity 120a and a freezing cavity 120b distributed along the height direction, and the refrigeration cavity 120a is located on the upper side of the freezing cavity 120b. The freezing cavity 120b can be provided with an air duct module 500, and the air duct module 500 can include a shell 501, a fan 520 and an evaporator 530. The shell 501 is arranged in the freezing cavity 120b along the depth direction of the freezing cavity 120b, and the shell 501 is provided with a cavity for gas circulation. The fan 520 and the evaporator 530 are arranged in the cavity, and the fan 520 is used to deliver cold air to the refrigeration cavity 120a and the freezing cavity 120b.

[0059] Taking the refrigeration equipment 1000 as a standing type side cabinet as an example, the refrigeration cavity 120 can include a refrigeration cavity 120a arranged on the upper side and a freezing cavity 120b arranged on the lower side. By arranging the refrigeration cavity 120a and the freezing cavity 120b, multiple temperature storage partitions can be realized. The refrigeration cavity 120a has a relatively high temperature and is used to store storage objects that need to be refrigerated and preserved. The freezing cavity 120b has a relatively low temperature and is used to store storage objects that need to be frozen and stored for a long time. It can be understood that the inner container 110 is provided with two corresponding refrigeration cavities 120a and freezing cavities 120b. Among them, the door body 200 for closing the corresponding cavity is arranged corresponding to the refrigeration cavity 120a and the freezing cavity 120b.

[0060] The air duct module 500 can recycle hot air and output cold air. The shell 501 is arranged along the depth direction of the freezing cavity 120b, thereby reducing the occupation of the entire air duct module 500 in the depth direction of the freezing cavity 120b. In the case that the thickness of the refrigeration equipment 1000 is thin, the freezing cavity 120b can also have sufficient depth, thereby improving the space utilization.

[0061] The shell 501 can be provided with a cavity for mounting devices such as the fan 520 and the evaporator 530. The cavity can include a supply air cavity 510 and a return air cavity 540. The fan 520 and the evaporator 530 can be arranged in the supply air cavity 510. The fan 520 is used to drive the circulation of cold air in the refrigeration cavity 120 and the shell 501, thereby improving the refrigeration efficiency. The evaporator 530 is used to absorb heat, thereby achieving the refrigeration effect. The fan 520 and the evaporator 530 can be fixed in the supply air cavity 510 by a support, thereby ensuring the stability and reliability thereof. Specifically, the fan 520 can deliver cold air cooled by the evaporator 530 to the freezing cavity 120b and the refrigerating cavity 120a. The return air cavity 540 can be in communication with the refrigerating cavity 120a and the freezing cavity 120b, so as to recycle the hot air in the refrigerating cavity 120a and the freezing cavity 120b to the supply air cavity 510 for circulation and refrigeration.

[0062] Please refer to Figures 3-6 According to some embodiments of the present application, the shell 501 is connected with the rear wall of the freezing cavity 120b in the depth direction. The end of the shell 501 connected with the rear wall is provided with a supply air port 502 extending in the lateral direction. The supply air direction of the supply air port 502 is arranged at an angle with respect to the side plate and the rear wall of the shell 501.

[0063] The rear wall of the freezing cavity 120b in the depth direction is the rear wall of the inner liner 110 of the freezing cavity 120b, which extends in the height direction. The end of the shell 501 for connecting with the rear wall is provided with a supply air port 502 extending in the lateral direction. The supply air port 502 is arranged at the rear end of the shell 501 and located at the rear end of the side corresponding to the freezing cavity 120b. By arranging the supply air port 502 at the corner position of the freezing cavity 120b, the occupation of the depth of the freezing cavity 120b is reduced. In the case that a drawer is arranged in the freezing cavity 120b, the interference with the drawer is reduced, thereby increasing the effective volume of the drawer and improving the storage space.

[0064] The air supply direction of the air supply port 502 is arranged at an angle with the side plate and the rear wall of the shell 501, that is, the air supply direction of the air supply port 502 is inclined and arranged towards the center position of the freezing cavity 120b where the air supply port 502 is located, so that the air supply port 502 can better circulate in the freezing cavity 120b, improve the refrigeration efficiency, and ensure the refrigeration effect. Specifically, taking the case that the shell 501 is arranged on the right side of the freezing cavity 120b as an example, the air supply port 502 is arranged at the right rear of the freezing cavity 120b where the air supply port 502 is located, so that the air supply direction of the air supply port 502 is towards the left front of the freezing cavity 120b where the air supply port 502 is located, that is, the cold air blown out by the air supply port 502 diffuses along the diagonal of the freezing cavity 120b, so that the temperature of the freezing cavity 120b where the air supply port 502 is located is more uniform, and the refrigeration effect is improved.

[0065] In addition, the air supply port 502 is arranged close to the shell 501, which shortens the circulation path of the air supply in the shell 501, improves the air supply speed, and also reduces the volume and number of structural members for extending the air supply port 502 to the middle of the freezing cavity 120b, thereby reducing the production cost and difficulty of the structural members.

[0066] Please refer to Figure 2 , Figure 4 and Figure 7 According to some embodiments of the present application, a volute 550 can be arranged in the cavity, and the fan 520 can be arranged in the volute 550. The volute 550 can have a first air outlet 551 and a second air outlet 552. The first air outlet 551 can be connected to the side of the shell 501 close to the rear wall, for air supply to the freezing cavity 120b. The width of the first air outlet 551 in the thickness direction of the shell 501 can gradually increase along the air outlet direction. The second air outlet 552 of the volute 550 can be connected to the upper part of the shell 501, for air supply to the refrigerating cavity 120a.

[0067] The volute 550 forms an air cavity therein for guiding airflow, so that the airflow can smoothly enter the air duct system from the outlet of the fan 520 and circulate in the air duct system, reducing turbulence and resistance of the airflow and improving stability of the airflow. By fixing and installing the fan 520 in the volute 550, stable support is provided for the fan 520, and a high air pressure is formed inside the volute 550 for the airflow generated by the fan 520, thereby improving the pushing capacity of the airflow and ensuring that the airflow can smoothly reach the target area. In addition, the volute 550 also plays a role in protecting the fan 520 and reducing noise.

[0068] The volute 550 is provided with a first air outlet 551 and a second air outlet 552 facing different directions. The first air outlet 551 is connected to the side of the shell 501 close to the rear wall, that is, the rear part of the shell 501, and the air outlet direction of the first air outlet 551 faces the rear wall of the refrigeration cavity 120 where the first air outlet 551 is located. Since the shell 501 is arranged in the freezing cavity 120b, the first air outlet 551 is used to deliver cold air into the freezing cavity 120b. The width of the first air outlet 551 in the thickness direction of the shell 501 gradually increases along the air outlet direction, so that the first air outlet 551 is flared along the air outlet direction. On the one hand, this can reduce the air supply resistance and reduce the air volume loss. On the other hand, the storage space of the freezing cavity 120b is located on one side in the thickness direction of the shell 501, so it is necessary to guide the cold air to one side in the thickness direction of the shell 501. Since the first air outlet 551 faces the rear side of the shell 501, by arranging the first air outlet 551 to be flared, the airflow can flow to the side, reducing the influence of turbulence and improving the air outlet efficiency and stability.

[0069] The second air outlet 552 is connected to the upper part of the shell 501, that is, the top in the height direction of the shell 501, to supply air to the refrigeration cavity 120a located on the upper part of the shell 501. The air volume output by the fan 520 can be directly distributed to the freezing cavity 120b and other refrigeration cavities 120 through the second air outlet 552. By directly arranging air outlets facing different directions on the volute 550, the bending and turning of the air outlet position are reduced, the air resistance is reduced, and the air outlet efficiency of the fan 520 is greatly improved. The overall air volume is high, the energy consumption is lower, and the performance and energy efficiency ratio of the refrigeration equipment 1000 are improved.

[0070] According to the air duct module 500 provided by the embodiments of the present application, by directly arranging the first air outlet 551 and the second air outlet 552 facing different directions on the volute 550, the air force output by the fan 520 is directly distributed to two refrigeration cavities 120 in two directions, the air volume loss is small, and the first air outlet 551 is flared to reduce the air supply resistance and further reduce the air volume loss, greatly improving the air outlet efficiency of the fan 520. The air volume is distributed to two refrigeration cavities 120 to simultaneously refrigerate the two refrigeration cavities 120, the overall air volume is high, and the energy consumption is lower.

[0071] Please refer to Figure 1 and Figure 2 According to some embodiments of the present application, a partition assembly 300 can be arranged in the refrigeration cavity 120a along the depth direction of the refrigeration cavity 120a. The partition assembly 300 can be arranged in the middle of the refrigeration cavity 120a to divide the refrigeration cavity 120a into two chambers. The shell 501 can be arranged in the middle of the freezing cavity 120b to divide the freezing cavity 120b into two chambers. The partition assembly 300 can be provided with an air supply pipe 311 in communication with the refrigeration cavity 120a and the fan 520.

[0072] The partition assembly 300 can be provided with a supply air pipe 311 in communication with the refrigeration cavity 120a and the fan 520, so that the cold air output by the fan 520 can be delivered to the refrigeration cavity 120a through the supply air pipe 311. By arranging the partition assembly 300 along the depth direction of the refrigeration cavity 120a, the occupation of the partition assembly 300 in the depth direction of the refrigeration cavity 120a is reduced, and in the case that the thickness of the refrigeration equipment 1000 is thin, the refrigeration cavity 120a can also have sufficient depth, thereby improving the space utilization.

[0073] By arranging the partition assembly 300 at the middle of the refrigeration cavity 120a in the width direction and arranging the air duct module 500 at the middle of the freezing cavity 120b in the width direction, the partition assembly 300 and the air duct module 500 are conveniently connected, and the refrigeration equipment 1000 is a vertical centering system, the air duct system of the refrigeration equipment 1000 is arranged at the middle of the refrigeration equipment 1000, and the refrigeration cavity 120a and the freezing cavity 120b are both divided into two chambers.

[0074] From the perspective of temperature control, different chambers can be set to different temperatures to meet the storage needs of different types of food, and the two chambers can be provided with respective door bodies 200, the temperature of each chamber can be independently controlled, the influence on the temperature of other chambers when the door is opened is reduced, and a stable storage environment is maintained. Each chamber can independently control the temperature, reduce unnecessary cold waste, improve overall energy efficiency, and small chambers are more easily and quickly cooled than large chambers, reducing the working time and energy consumption of the compressor.

[0075] From the perspective of space utilization, the partition assembly 300 can be adjusted according to actual needs, so that users can flexibly allocate storage space according to the size and quantity of food, different types of storage objects can be stored separately to avoid cross-infection and maintain the freshness and hygiene of the storage objects. Users can also quickly find the required objects according to the type of storage objects, improve the convenience of taking objects, reduce the door opening time, and further reduce the loss of cold. Different chambers can effectively isolate the odors between foods and keep the air inside the refrigerator fresh.

[0076] Please refer to Figure 2 , Figure 8 and Figure 9 , the refrigeration equipment 1000 can further include a supply and return air integrated shell 400, the supply and return air integrated shell 400 can be arranged between the refrigeration cavity 120a and the freezing cavity 120b and connected with the partition assembly 300 and the shell 501 respectively, the supply and return air integrated shell 400 is provided with a supply air passage 411 and a return air passage 421, the two ends of the supply air passage 411 are in communication with the fan 520 and the supply air pipe 311 respectively, and the return air passage 421 is in communication with the cavity and the refrigeration cavity 120a respectively.

[0077] The air supply passage 411 and the air return passage 421 are integrated in the air supply and return integrated shell 400, and cold air is supplied and recovered to the refrigeration cavity 120a through the air supply and return integrated shell 400 to realize the circulation of the cold air in the refrigeration cavity 120a. The air supply and return integrated shell 400 simplifies the structure of the air duct system in the refrigeration equipment 1000, reduces the space occupation, facilitates assembly, and greatly improves the assembly efficiency and assembly precision.

[0078] The air supply and return integrated shell 400 is arranged between the air duct module 500 and the partition assembly 300, and the two ends of the air supply passage 411 are communicated with the air fan 520 and the air supply pipe 311, so that the cold air output by the air fan 520 can enter the air supply pipe 311 through the air supply passage 411 and then be supplied to the refrigeration cavity 120a. The air return passage 421 is communicated with the cavity and the refrigeration cavity 120a respectively to recover the hot air in the refrigeration cavity 120a to the air duct module 500 through the air return passage 421, and specifically, the air return passage 421 is communicated with the air return cavity 540 of the cavity.

[0079] Please refer to Figure 8 and Figure 9 According to some embodiments of the present application, the air supply passage 411 and the air return passage 421 can be distributed along the depth direction of the refrigeration cavity 120a, and the air return passage 421 can be located on the side of the air supply passage 411 close to the door body 200.

[0080] The air supply passage 411 and the air return passage 421 of the air supply and return integrated shell 400 are also distributed along the depth direction of the refrigeration cavity 120a and the freezing cavity 120b, so that the air supply and return integrated shell 400 has little effect on the thickness of the refrigeration equipment 1000 and has little effect on the width and depth of the internal refrigeration cavity 120, thereby improving the internal space utilization rate of the refrigeration equipment 1000. Specifically, the air duct module 500, the air supply and return integrated shell 400, and the partition assembly 300 can be directly opposite in the height direction, facilitating the butt joint of the air duct system and reducing the effect on the thickness of the refrigeration equipment 1000 and the effective volume of the refrigeration cavity 120a and the freezing cavity 120b, thereby improving the overall refrigeration effect and space utilization rate.

[0081] The door body 200 is arranged at the opening of the refrigeration cavity 120a to seal the refrigeration cavity 120a together with the box body 100, and the air return passage 421 is arranged on the side of the air supply passage 411 close to the door body 200, that is, the air return port 313 in the refrigeration cavity 120a is located on the side close to the opening of the refrigeration cavity 120a.

[0082] By setting the return air passage 421 close to one side of the door body 200, when the door is opened, the warm air from outside can enter the inside of the refrigeration cavity 120a, and the side of the return air passage 421 close to the door body 200 can quickly suck in and cool these warm air, reducing temperature fluctuations and maintaining the stability of the temperature inside the cavity. Because the return air passage 421 can quickly exhaust the incoming warm air, the compressor working time is shortened, thereby reducing energy consumption and improving energy efficiency. The side of the return air passage 421 close to the door can more effectively exhaust the moisture at the door gap, reducing the formation of condensed water and keeping the inside of the refrigerator dry. In addition, the position of the return air port 313 does not affect the user's taking and placing food, because most users are used to taking things from the side close to the door, and the air supply passage 411 is set on the side away from the door body 200, avoiding the user from opening the door to take things. The direct blowing of cold air, such design is more humanized, improves the user experience.

[0083] And, the problem of multiple online assembly processes of refrigeration components and air ducts in existing products is solved, the assembly difficulty is reduced, the labor cost is reduced, and the assembly efficiency is improved. In addition, the idle space inside the refrigerator is fully utilized, thereby increasing the internal volume of the refrigeration cavity 120a and the freezing cavity 120b, and realizing large-space storage of the refrigeration equipment 1000.

[0084] Please refer to Figure 2 and Figure 9 According to some embodiments of the present application, two air supply pipes 311 can be arranged in the partition assembly 300 along the depth direction of the refrigeration cavity 120a, the two air supply pipes 311 can respectively communicate with two chambers of the refrigeration cavity 120a, and the air supply passage 411 can be provided with two corresponding air supply pipes 311. Two air supply passages 411 and return air passages 421 can be distributed along the depth direction of the refrigeration cavity 120a.

[0085] By arranging 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 refrigeration cavity 120a, which facilitates precise air supply to the two chambers of the refrigeration cavity 120a. The air supply and return integrated shell 400 is provided with two air supply passages 411 corresponding to the two air supply pipes 311, air is supplied to the corresponding air supply pipe 311 through the corresponding air supply passage 411, and the temperature control precision is improved.

[0086] Among them, two air supply passages 411 and return air passages 421 are arranged along the depth direction of the refrigeration cavity 120a, and the corresponding two air supply pipes 311 are also arranged along the depth direction of the refrigeration cavity 120a, so as to reduce the occupation of the air supply and return integrated 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 of the air supply passage 411 and the air supply pipe 311.

[0087] In some embodiments, the return air passage 421 can simultaneously communicate with two chambers of the refrigeration cavity 120a, so that the hot air of the two chambers of the refrigeration cavity 120a can be returned to the air duct module 500 through the return air passage 421, the return air efficiency is high, the use of one return air passage 421 can simplify the design of the interior of the refrigeration device 1000, reduce the number of required pipes and components, thereby saving space, improving space utilization and assembly efficiency.

[0088] In addition, the single return air structure can increase the size of the return air passage 421 due to the saved space occupied by the component structure, reduce the resistance of air flow, improve the cold air circulation efficiency, thereby reducing the working time and energy consumption of the compressor. It can also reduce the noise of air flow and improve the quiet experience of users when using the refrigerator. It can also reduce the potential failure points and improve the reliability and stability of the system. The single return air structure is easier to locate and repair when it fails, reducing maintenance time and cost.

[0089] Please refer to Figure 10 and Figure 11 , Figure 10 and Figure 11 respectively represent two kinds of odor removal devices 330 and odor removal air ducts 340. According to some embodiments of the present application,

[0090] According to some embodiments of the present application, the odor removal device 330 and the odor removal air duct 340 can be provided in the partition assembly 300, the inlet of the odor removal device 330 can communicate with the odor removal air duct 340, the outlet of the odor removal device 330 can communicate with the return air passage 421, and the odor removal air duct 340 can communicate with the refrigeration cavity 120a.

[0091] The odor removal air duct 340 communicating with the refrigeration cavity 120a can be provided in the partition assembly 300, the partition assembly 300 can include two partitions 310 arranged at intervals, and an odor removal device mounting position 320 for fixing the odor removal device 330 can be further provided between the two partitions 310. The odor removal device 330 is fixed in the odor removal device mounting position 320, and the inlet of the odor removal device 330 is connected with the odor removal air duct 340. The air in the refrigeration cavity 120a can enter the odor removal device 330 through the odor removal air duct 340 to remove odor, and then be discharged through the outlet of the odor removal device 330, thereby playing a role in removing odor. By connecting the outlet of the odor removal device 330 with the return air passage 421, the circulation efficiency of the gas in the refrigeration cavity 120a is improved, and the odor removal effect is improved.

[0092] In an example, the odor removal device 330 can be a self-powered odor removal device 330, and a small fan can be provided in the odor removal device 330. The odor removal device 330 actively absorbs the gas in the refrigeration cavity 120a through the odor removal air duct 340 when it works, the odor removal effect is good, and the odor removal efficiency is improved.

[0093] In another example, the odor eliminator 330 can be a passive odor eliminator 330, by connecting the return air channel 421 with the outlet of the odor eliminator 330, and the inlet of the odor eliminator 330 is connected with the odor elimination air duct 340, so that the negative pressure of the return air channel 421 drives part of the air in the refrigeration cavity 120a to be recycled to the return air channel 421 through the odor elimination air duct 340, and after entering the odor elimination air duct 340, it passes through the odor eliminator 330 to play a role in odor elimination. The structure is simple, the cost is low, and the use stability is high.

[0094] In the case where the refrigeration cavity 120a includes two chambers arranged at intervals:

[0095] In an example, as shown in Figure 10 , the odor elimination air duct 340 can be provided with one, two partitions, and each partition is provided with an air inlet 341 connected with the odor elimination air duct 340, which simplifies the air duct structure and improves the space utilization. It should be noted that Figure 10 only one air inlet 341 of one partition 310 is shown, and the air inlet 341 of the other partition 310 corresponds to the position of the air inlet 341 in the figure. It can be judged according to the width of the odor elimination air duct 340 and the inlet width of the odor eliminator 330.

[0096] In another example, as shown in Figure 11 , the odor elimination air duct 340 can be provided with two, two odor elimination air ducts 340 are connected with two chambers respectively, and two air inlets 341 corresponding to two odor elimination air ducts 340 are arranged on two partitions 310 respectively. By providing two odor elimination air ducts 340, the odor elimination efficiency can be improved, and the risk of odor mixing between the two chambers can be reduced. It should be noted that Figure 11 the odor eliminator 330 and the odor elimination air duct 340 are not shown, the position of the odor elimination air duct 340 can be judged according to the position of the air inlet 341, and the width of the odor elimination air duct 340 can be judged according to the width of the air inlet 341. From Figure 11 it can be seen that the width of the air inlet 341 is less than half the width of the inlet of the lower odor eliminator 330, so that the other odor elimination air duct 340 is located in the front side of the air inlet 341 in the figure, and the air inlet 341 on the other partition 310 is located in the front side of the air inlet 341 in the figure.

[0097] Specifically, the two odor elimination air ducts 340 can be distributed along the depth direction of the refrigeration cavity 120a, and the inlet of the odor eliminator 330 can extend along the depth direction of the refrigeration cavity 120a to connect with the two odor elimination air ducts 340. This setting can reduce the influence of the odor eliminator 330 and the odor elimination air duct 340 on the thickness of the partition assembly 300, and improve the space utilization.

[0098] Please refer to Figure 10 and Figure 11According to some embodiments of the present application, the end of the partition assembly 300 connected with the air supply and return integrated shell 400 can be provided with a communication cavity 312 in communication with the refrigeration cavity 120a, and the communication cavity 312 can be connected with the return air passage 421, and the outlet of the odor eliminator 330 can be arranged in the communication cavity 312.

[0099] The communication cavity 312 is arranged on the side close to the return air passage 421 to communicate with the return air passage 421, and specific reference can be made to the foregoing embodiments, which will not be described here again.

[0100] At least part of the odor eliminator 330 can be located in the communication cavity 312, and specifically, the outlet of the odor eliminator 330 can be arranged in the communication cavity 312, so that the odor eliminator 330 is arranged close to the return air passage 421, thereby optimizing the space layout and reducing the space occupied by the air duct.

[0101] In addition, in some embodiments, the partition assembly 300 can further include an access panel 314, and the return air inlet 313 is arranged on the access panel 314, so that the access panel 314 is opposite to the communication cavity 312, and after the access panel is opened, the odor eliminator 330 can also be maintained and repaired at the same time, thereby improving the convenience of maintenance and repair, improving the maintenance efficiency, and reducing the maintenance cost.

[0102] Please refer to Figure 12 and Figure 13 According to some embodiments of the present application, the air supply passage 411 can be provided with an air door 412 arranged at an angle with the horizontal direction.

[0103] Figure 12 The air door 412(a) and the air door 412(b) respectively represent the schematic diagrams of the air door 412 in the closed state and the open state.

[0104] The air door 412 arranged in the air supply passage 411 can be used to open or close the air supply passage 411 to adjust the air volume delivered into the refrigeration cavity 120a, thereby realizing the temperature adjustment of the refrigeration cavity 120a. For example, when the temperature of the refrigeration cavity 120a does not reach the set temperature, the air door 412 is controlled to be opened to deliver cold air into the refrigeration cavity 120a to reduce the temperature of the refrigeration cavity 120a; when the temperature of the refrigeration cavity 120a reaches or exceeds the set requirement, the air door 412 can be closed to stop delivering cold air into the refrigeration cavity 120a. In some examples, the opening degree of the air door 412 can also be controlled to adjust the flow area of the air supply passage 411, thereby changing the air volume of the cold air delivered into the corresponding refrigeration cavity 120a, and realizing the precise control of the temperature.

[0105] The temperature of the refrigeration cavity 120a is relatively high compared to the temperature in the air duct module 500, and thus the air door 412 or the inner wall of the air supply passage 411 has a risk of generating condensate water. After the condensate water is generated, if the condensate water is accumulated at the position of the door body 200, there is a high probability that the air door 412 is frosted at the position of the air door 412 under the action of the cold air of the air duct module 500 below zero degree, which may affect the air supply efficiency, or even freeze the air door 412 to be unable to be normally opened or closed, and thus damage the air door 412 and affect the refrigeration effect.

[0106] The air door 412 is arranged at an angle with the horizontal direction, that is, the door body 200 of the air door 412 is arranged to be inclined relative to the horizontal direction. When the condensate water generated on the air door 412 body or the condensate water generated at other positions falls on the air door 412, the condensate water can flow away along the inclined direction of the air door 412 under the action of gravity, so that the condensate water is drained away before the condensate water is frosted, thereby reducing the risk of frosting of the air door 412, improving the service life and use stability of the air door 412, and further improving the overall refrigeration effect.

[0107] According to some embodiments of the present application, the thickness S of the door body 200 can satisfy 25mm≤S≤40mm.

[0108] The thickness of the door body 200 of the refrigeration equipment 1000 is thin, which is convenient to open, and reduces the influence on the thickness of the entire refrigeration equipment 1000, so that the refrigeration equipment 1000 can be made thinner to better adapt to the indoor decoration of the user and improve the product quality. The thickness S of the door body 200 is in the range of [25mm, 50mm], and for example, S can be 25mm, 30mm, 35mm, 40mm or other values between 25mm and 40mm, and the specific value is not limited.
