[0002] This application claims priority to Chinese Patent Application No. 202411710373.8, filed on November 26, 2024, entitled "A Refrigeration Device", which is incorporated herein by reference in its entirety. Technical Field

[0003] This application belongs to the field of household appliance technology, and in particular relates to a refrigeration device. Background Technology

For a single-system refrigeration equipment, the refrigeration component can also be installed in only one air duct module, and this air duct can be connected to other air ducts to achieve air supply from one set of refrigeration components to multiple air duct modules. However, in related technologies, two air ducts are directly connected to each other to achieve air supply, but the air duct modules are relatively large, and direct connection is inconvenient.

[0039] The refrigeration equipment has multiple air duct modules to supply air to different chambers. Each air duct module can be equipped with a set of refrigeration components to cool the gas, or the refrigeration component can be installed in only one air duct module, and this air duct can be connected to other air ducts to achieve air supply from one set of refrigeration components to multiple air duct modules. However, in related technologies, two air ducts are directly connected to each other to achieve air supply, but the air duct modules are relatively large, and direct connection is inconvenient.

[0040] To address the problems existing in related technologies to some extent, this application provides a refrigeration device that can precisely connect the supply air duct and the outlet air duct by simply adjusting the position of the connecting air duct, thereby greatly improving the convenience of connecting the supply air duct and the outlet air duct.

[0041] This application is described below with reference to the accompanying drawings and specific embodiments.

[0042] Please refer to Figures 1-3. The refrigeration device 10 provided in this application embodiment can accurately connect the supply air duct 110 and the outlet air duct 220 by simply adjusting the position of the connecting air duct 300, thereby greatly improving the convenience of connecting the supply air duct 110 and the outlet air duct 220.

[0043] The refrigeration device 10 can be a freezer or a refrigerator. In this embodiment, for ease of description, a refrigerator is used as an example for illustrating the refrigeration device 10. The same principle applies when the refrigeration device 10 is another device.

[0044] The refrigeration device 10 is roughly rectangular. For ease of description, the height direction Z, width direction X, and thickness direction Y are defined. In the operating state of the refrigeration device 10, the vertical direction is the height direction Z, and the projection of the refrigeration device 10 in the vertical direction is a rectangle. The direction of the longer side is the width direction X, and the direction of the shorter side is the thickness direction Y.

[0045] Similarly, for ease of description, six directions are defined: up, down, left, right, front, and back. In the height direction Z, up is closer to the top surface and down is further away from the top surface; in the width direction X, left and right are respectively. The chamber 140 of the refrigeration device 10 has a loading / unloading opening, and a door 700 is provided at the loading / unloading opening. In the thickness direction Y, forward is closer to the door 700 and backward is further away from the door 700.

[0046] Please refer to Figures 3-5. In this embodiment of the application, the refrigeration device 10 includes a housing 100 and an air duct module 200. The housing 100 has a chamber 140 for containing items; the air duct module 200 is installed in the housing 100 and includes an air duct housing 200a and an outlet air duct 220 and a transfer air duct 300 disposed within the air duct housing 200a. The outlet air duct 220 is used to supply air to the chamber 140 of the refrigeration device 10, and the transfer air duct 300 has a transition air duct 400 connecting the outlet air duct 220 and the supply air duct 110.

[0047] The connecting air duct 300 and the outlet air duct 220 are detachably connected.

[0048] The housing 100 is the main structure of the entire refrigeration equipment 10. It provides an installation base for structures such as the air duct module 200, the air intake component 130, and the evaporator 120, and also protects the aforementioned electronic components. The chamber 140 is used to hold items to be refrigerated or frozen. The chamber 140 has an access port, through which users can access and place items.

[0049] The air duct module 200 is installed in the housing 100. The air duct shell 200a is the main structure of the air duct module 200, providing the installation foundation for structures such as the outlet air duct 220 and the transfer air duct 300. In this embodiment, the housing 100 also has an air supply duct 110. The chamber 140 of the refrigeration equipment 10 includes a freezing chamber 142 and a refrigeration chamber 141. The air supply duct 110 can be used to supply air to the freezing chamber 142, and the air outlet duct 220 is used to supply air to the refrigeration chamber 141. The refrigeration chamber 141 is above the freezing chamber 142, therefore the air outlet duct 220 is above the air supply duct 110.

[0050] The refrigeration equipment 10 also includes an evaporator 120 and a flow guide 130. The evaporator 120 is used to cool the air, and the flow guide 130 is used to circulate the cold air in the chamber 140 to cool the items. Since the freezing chamber 142 requires a larger cooling capacity, the evaporator 120 and the flow guide 130 can be installed in the air supply duct 110. That is, the air cooled by the evaporator 120 can directly enter the freezing chamber 142 through the air supply duct 110. When the air supply duct 110 and the air outlet duct 220 are connected, the cold air in the air supply duct 110 can enter the air outlet duct 220 to cool the refrigeration chamber 141. Specifically, the duct housing 200a has an air outlet 221 and a return air outlet 222 that are connected to the air outlet duct 220. The guide member 130 enables the gas in the chamber 140 to enter the air supply duct 110 through the return air outlet 222, and the gas in the air outlet duct 220 to flow from the air outlet 221 to the outlet chamber 140.

[0051] The cabinet 100 may have a partition inside, which is used to divide the refrigerator cavity 141 and the freezer cavity 142 into two or more independent compartments to better classify and store different types of food, such as vegetables, fruits, and dairy products, thereby facilitating management and maintaining the optimal freshness of the food. Both the refrigerator cavity 141 and the freezer cavity 142 have partitions, and the air supply duct 110 and the air outlet duct 220 can be located inside the partition. That is, the partition in the refrigerator cavity 141 is configured as the air duct shell 200a, so the air outlet 221 and the air return vent 222 can be located inside the partition. By using the partition to support and accommodate the air supply duct 110 and the air outlet duct 220, the internal space of the partition can be effectively utilized, reducing the space occupied by the air ducts and making the overall structure more compact.

[0052] Since the transition duct 300 has a transition duct for connecting the outlet duct 220 and the supply duct 110, and the transition duct 300 and the outlet duct 220 are detachably connected, when connecting the outlet duct 220 and the supply duct 110, the supply duct 110 and the outlet duct 220 can be connected separately through the transition duct to achieve the connection between the supply duct 110 and the outlet duct 220. That is, during the connection process, there is no need to move the position of the entire duct module 200. Only the position of the transition duct 300 needs to be adjusted to make the supply duct 110 and the outlet duct 220 accurately connected, thereby greatly improving the convenience of connecting the supply duct 110 and the outlet duct 220.

[0053] In the detachable connection between the transition air duct 300 and the outlet air duct 220, the transition air duct 300 and the outlet air duct 220 can be fixedly connected or only in contact. The detachable connection between the transition air duct 300 and the outlet air duct 220 means that the transition air duct 300 can be separated from the outlet air duct 220, so that the position of the transition air duct 300 can be adjusted so that the transition air duct 400 can be connected to the supply air duct 110 and the outlet air duct 220 respectively.

[0054] It should be explained that the air outlet duct 220 described in this embodiment includes the air outlet duct 220 body (virtual body) and the air outlet component (physical body) forming the air outlet duct 220 body. When described herein as being connected to the air outlet channel, it means being connected to the air outlet duct 220 body; when described herein as being connected to or in contact with the air outlet channel, it means being connected to or in contact with the air outlet component. Similarly, the air supply duct 110 includes the air supply duct 110 body and the air supply component forming the air supply duct 110 body, and its meaning is the same as that of the air outlet duct 220, and will not be repeated here.

[0055] Please refer to Figures 5 and 6. In some embodiments, the transition duct 300 has a first transition surface 321, and the outlet duct 220 has an outlet surface 223. The first transition surface 321 is in contact with the outlet surface 223.

[0056] The transition duct 300 and the outlet duct 220 are connected by contact and are not fixedly connected. Therefore, when it is necessary to connect the supply air duct 110 and the outlet duct 220, maintenance personnel can simply adjust the position of the transition duct 300. Of course, the transition duct passes through the first transition surface 321, and the outlet duct 220 passes through the outlet surface 223. Thus, the contact between the first transition surface 321 and the outlet surface 223 is sufficient to connect the transition duct and the outlet duct 220.

[0057] When connecting the supply air duct 110 and the outlet air duct 220, first install the transition air duct 300 inside the air duct housing 200a, and make the first transition surface 321 contact the outlet surface 223. Then, slightly adjust the relative positions of the transition air duct 300 and the outlet air duct 220 so that they are connected to the supply air duct 110 and the outlet air duct 220 respectively.

[0058] Of course, in other embodiments, a snap-fit ​​structure can also be added between the transition duct 300 and the outlet duct 220 for positioning and fixing. For example, the first transition surface 321 and the outlet surface 223 may have a snap-fit ​​component on one and a snap-fit ​​groove on the other. When installing the transition duct 300, the snap-fit ​​component is snapped into the snap-fit ​​groove to position the transition duct 300, so that the transition duct 400 connects the outlet duct 220 and the supply duct 110. The snap-fit ​​structure can also fix the relative position of the first transition surface 321 and the outlet surface 223, making the transition effect more stable. Alternatively, a fastener can be provided to detachably connect the first transition surface 321 and the outlet surface 223. There are no restrictions on this.

[0059] In some embodiments, the first transition surface 321 and the air outlet surface 223 are arranged at an angle.

[0060] That is, the first transition surface 321 and the air outlet surface 223 have an angle with the horizontal plane. It can be understood that the first transition surface 321 and the air outlet surface 223 have the same tilt angle. Due to the inclined surface fit between the first transition surface 321 and the air outlet surface 223, the first transition surface 321 and the air outlet surface 223 have a self-positioning function when they come into contact, which can make the positioning of the transition air duct and the air outlet air duct 220 more accurate.

[0061] Furthermore, since the air outlet duct 220 and the transition duct 400 are connected through the contact between the first transition surface 321 and the air outlet surface 223, a seal is required between the first transition surface 321 and the air outlet surface 223 to reduce cold air leakage. The beveled fit between the first transition surface 321 and the air outlet surface 223 also makes the fit tighter, resulting in better sealing between the transition duct 300 and the air outlet duct 220, thereby reducing cold air leakage.

[0062] Referring to Figure 10, in some embodiments, the transition duct 300 further includes a seal 350, which is installed in the transition duct 300 and at least a portion of the seal 350 is located between the first transition surface 321 and the outlet surface 223.

[0063] Since the transition duct 400 is connected to the outlet duct 220, cold air enters the outlet duct 220 through the transition duct 400. Since the connecting duct 300 and the outlet duct 220 are detachably connected, there is a small gap between the first connecting surface 321 and the outlet surface 223. Therefore, in order to reduce the leakage of cold air, a sealing element 350 needs to be installed on the connecting duct 300 to seal the gap between the first connecting surface 321 and the outlet surface 223.

[0064] At least a portion of the seal 350 is located between the first transition surface 321 and the air outlet surface 223. This means that either all of the seal 350 is attached to the first transition surface 321, or only a portion of the seal 350 is attached to the first transition surface 321, and the remaining portion is attached to other surfaces of the transition duct 300. Once the transition duct 300 is installed in place, the seal 350 is positioned between the first transition surface 321 and the air outlet surface 223 to provide a seal.

[0065] Specifically, the seal 350 can be made of PU sponge, and the thickness of the seal 350 can be 2mm to 4mm.

[0066] Please refer to Figure 5. In some embodiments, the duct housing 200a includes a housing 210 and a mounting member 240. The air outlet duct 220 is disposed inside the housing 210. The housing 210 has an inspection window 230. The transfer duct 300 is installed in the inspection window 230. The mounting member 240 covers a portion of the transfer duct 300.

[0067] The supply air duct 110 is located below the outlet air duct 220. Since the transition air duct 300 is installed in the maintenance window 230 and the transition air duct 300 connects the outlet air duct 220 and the supply air duct 110, the maintenance window 230 is located below the outlet air duct 220, and the outlet surface 223 is located inside the maintenance window 230. Therefore, the transition air duct 300 is installed inside the maintenance window 230, and the first transition surface 321 can contact the outlet surface 223.

[0068] Since the adapter duct 300 is installed inside the inspection window 230 and is detachably connected to the outlet duct 220, when maintenance is required on the outlet duct 220, the adapter duct 300 is removed from the duct housing 200a, exposing the outlet duct 220 through the inspection window 230. Maintenance personnel can then perform maintenance on the outlet duct 220 directly through the inspection window 230. In other words, when maintenance is required on the outlet duct 220, only the adapter duct 300 needs to be removed, without dismantling the entire duct module 200, thus significantly saving manpower, resources, and time, and shortening the maintenance cycle.

[0069] Since the transition duct 400 is connected to the outlet duct 220 and the supply duct 110, cold air will be transferred between the outlet duct 220 and the supply duct 110. Therefore, the cold air will pass through the transition duct 400. In order to reduce the amount of cold air lost when passing through the transition duct 400, at least part of the adapter 320 needs to be made of thermal insulation material such as foam. Therefore, the structure is relatively fragile and needs to be protected by the mounting part 240. The housing 210 and the mounting part 240 can be integrally molded. If the mounting part 240 completely covers the transition duct 300, it will close the inspection window 230, making it inconvenient for maintenance personnel to perform maintenance on the outlet duct 220 through the inspection window 230. Therefore, the mounting part 240 only covers a part of the transition duct 300, that is, it protects a part of the transition duct 300. The transition duct 300 and the mounting part 240 can be connected, in contact, or separated, without restriction.

[0070] Furthermore, since the mounting component 240 only covers a portion of the transfer duct 300, it also facilitates the installation of the transfer duct 300. Specifically, the mounting component 240 can cover one side of the transfer duct 300. In other words, the mounting component 240 can be installed on one side of the inspection window 230, leaving an opening on the other side of the inspection window 230. Therefore, when installing the transfer duct 300, the transfer duct 300 can enter the inspection window 230 from the opening on the other side and come into contact with the outlet duct 220.

[0071] In some embodiments, the transition duct 300 includes a cover plate 310 and a transition member 320. The transition duct 400 and the first transition surface 321 are disposed on the transition member 320. A fixing cavity 241 is formed between the cover plate 310 and the mounting member 240. The transition member 320 is located in the fixing cavity 241 and is installed on the cover plate 310. The cover plate 310 is detachably connected to the housing 210.

[0072] Since a fixed cavity is formed between the cover plate 310 and the mounting member 240, and the adapter 320 is located within the fixed cavity 241, the adapter 320 can be covered by both the cover plate 310 and the mounting member 240 to protect the adapter 320 as a whole, making it less susceptible to damage. Specifically, the cover plate 310 and the mounting member 240 can be respectively disposed on both sides of the adapter 320 along the width direction, thereby covering both sides of the adapter 320 along the width direction, while the front and rear of the adapter 320 abut against the inner wall of the inspection window 230. Of course, the first transition surface 321 is located on the top of the adapter 320.

[0073] The air outlet duct 220 is fixedly installed inside the housing 210, and the air outlet duct 220 and the housing 210 can be regarded as an integral unit. The adapter 320 is installed on the cover plate 310, which means that the adapter 320 and the cover plate 310 are fixedly connected. Since the cover plate 310 and the housing 210 are detachably connected, and the adapter 320 is installed on the cover plate 310, the adapter duct 300 achieves a detachable connection with the air outlet duct 220 through a detachable connection with the housing 210. Therefore, the adapter duct 300 only needs to contact the air outlet duct 220. When installing the transition duct 300, first insert the transition duct 300 into the inspection window 230 through the opening, so that the first transition surface 321 contacts the air outlet surface 223. Then, finely adjust the position of the transition duct 300 so that the transition duct connects the supply air duct 110 and the outlet air duct 220. Finally, connect the cover plate 310 and the housing 210.

[0074] Furthermore, the entire adapter 320 is covered, which also improves the aesthetics and cleanliness of the air duct module 200.

[0075] Referring to Figures 5 and 6, in some embodiments, the cover plate 310 has a connecting portion 311 extending from the adapter 320, the connecting portion 311 being detachably connected to the housing 210.

[0076] Since the inspection window 230 is located within the housing 210, and the adapter 320 is situated within the inspection window 230, the cover plate 310 needs to extend the adapter 320 to connect with the housing 210. Specifically, the cover plate 310 can extend the adapter 320 upwards, forwards, or backwards to connect with the housing 210. The connection portion 311 is detachably connected to the housing 210 via screws, snap-fits, riveting, or other means, and there are no restrictions on this connection method.

[0077] Please refer to Figures 5 and 6. In some embodiments, the refrigeration device 10 further includes a limiting platform 500, which is disposed on the inner wall of the chamber 140, and the cover plate 310 abuts against the limiting platform 500.

[0078] Since the cover plate 310 and the housing 210 are detachably connected, the connection force between the cover plate 310 and the housing 210 may weaken after long-term use, causing the transfer duct 300 to shift slightly. However, since the cover plate 310 abuts against the limiting platform 500, the transfer duct 300 can be limited, keeping its position as fixed as possible and ensuring the transfer effect.

[0079] Furthermore, the limiting platform 500 can also position the transfer duct 300. That is, when the transfer duct 300 is installed, the cover plate 310 abuts against the limiting platform 500, which is the accurate position of the transfer duct 300. This can reduce the time spent adjusting the position of the transfer duct 300 and improve installation efficiency.

[0080] Of course, since the partition in the refrigeration chamber 141 is configured as the air duct shell 200a, that is, the partition is used to install and support the air duct, and the partition is not integrally set with the cabinet 100, in order to make the installation of the partition more stable, the left and right sides of the transition air duct 300 can be provided with limiting platforms 500, and the cover plate 310 abuts with one of the limiting platforms 500, and the mounting piece 240 abuts with the other limiting platform 500. Thus, the limiting platforms 500 on both sides can jointly limit the air duct module 200 in the width direction, making the installation of the air duct module 200 more stable.

[0081] In some embodiments, the air duct module 200 further includes an odor removal module 900 and an odor removal air duct 160 disposed in the air duct housing 200a. The odor removal air duct 160 is disposed at a distance from the air outlet air duct 220. The odor removal module 900 is installed in the odor removal air duct 160. The air duct housing 200a also has a return air inlet 222 that communicates with the return air duct 150. The odor removal air duct 160 is connected to the return air inlet 222.

[0082] Please refer to Figure 11. If strong-smelling foods, such as dried pickles or hot pot base, are stored in the refrigeration unit 10, the odor will transfer to other items, resulting in a poor user experience. Therefore, an odor removal module 900 is required for odor removal. The return air duct 150 is located in the refrigeration unit 10. Gas in the chamber 140 can enter the return air duct 150 through the return air inlet 222 and then enter the supply air duct 110 for cooling. The cooled air then passes through the transition air duct 400 and enters the supply air duct 110 to blow air into the chamber 140, achieving gas circulation. Since the odor removal duct 160 is connected to the return air inlet 222, the gas in the chamber 140 can also enter the odor removal module 900 through the return air inlet 222. After purification by the odor removal module 900, the clean gas is then blown out through the odor removal duct 160. In other words, odor removal and return air share a single return air inlet 222, further simplifying the structure.

[0083] Specifically, the odor-removing air duct 160 can be installed in the housing 210, and the odor-removing module 900 can be installed in the adapter 320. Therefore, the adapter air duct 300 can not only be used to connect the outlet air duct 220 and the supply air duct 110, but also integrates the function of installing the odor-removing module 900. Therefore, when the adapter air duct 300 is applied to the refrigeration equipment 10, there is no need to set up a structure for installing the odor-removing module 900 in the refrigeration equipment 10, thereby simplifying the structure of the refrigeration equipment 10.

[0084] Please refer to Figures 5 and 6. In some embodiments, the refrigeration device 10 further includes a partition 600 installed on the housing 100. The partition 600 has a vent 610 that can connect the air supply duct 110 and the air outlet duct 220. The partition 600 is located between the air outlet duct 220 and the air supply duct 110. The partition 600 is provided with an air supply surface 630. The transfer duct 300 has a second transfer surface 322 that contacts the air supply surface 630.

[0085] The cold air in the supply air duct 110 enters the outlet air duct 220 sequentially through the vent 610 and the transition air duct. Of course, the transition air duct passes through the second transition surface 322, and the vent 610 passes through the outlet air surface 223. Thus, the contact between the second transition surface 322 and the supply air surface 630 enables the transition air duct and the outlet air duct 220 to be connected.

[0086] Of course, the refrigeration equipment 10 also includes a damper assembly 620 installed on the partition 600. The damper assembly 620 is used to open or close the vent 610 to connect or separate the transition duct and the supply air duct 110, and the air volume can be adjusted by controlling the opening degree of the damper assembly 620. The supply air surface 630 is disposed on the top of the partition 600. In order not to affect the cooperation between the supply air surface 630 and the second transition surface 322, the damper assembly 620 is disposed on the side of the partition 600 away from the transition air duct 300.

[0087] Please refer to Figures 8 and 9. In some embodiments, the transition duct 300 is provided with a docking groove 330 communicating with the transition duct, and the separator 600 is provided with a docking part 640 communicating with the vent 610. The docking part 640 is installed in the docking groove 330.

[0088] Since the docking groove 330 is connected to the transition air duct, and the docking part 640 is connected to the vent 610, the docking part 640, installed in the docking groove 330, allows the transition air duct to connect with the vent 610. That is, the docking fit between the docking part 640 and the docking groove 330 further positions the transition air duct 300, improving its positioning efficiency and fixing the relative position between the transition air duct 300 and the partition 600. Of course, since the positions of the outlet air duct 220, the supply air duct 110, and the partition 600 are all fixed, and the relative position between the transition air duct 300 and the partition 600 is fixed, the relative position between the transition air duct 300 and the outlet air duct 220 is also fixed.

[0089] Please refer to Figures 3 and 4. In some embodiments, the refrigeration device 10 also includes a drawer 800, which is installed in the chamber 140. The transfer air duct 300 is provided with a slide rail 340 on the side facing the chamber 140, and the drawer 800 cooperates with the slide rail 340.

[0090] Drawer 800 is used to place items, and chamber 140 has an access opening. Drawer 800 can slide into or out of chamber 140 through the access opening to retrieve items. Since the partition is configured as the air duct housing 200a, the transfer air duct 300 is also located within the partition, meaning the transfer air duct 300 is also part of chamber 140. In this embodiment, utilizing the location of the transfer air duct 300, a slide rail 340 is provided on the side of the transfer air duct 300 facing chamber 140. Drawer 800 slides in conjunction with slide rail 340, thereby realizing the sliding function of drawer 800. In other words, transfer air duct 300 can not only be used for maintenance of air outlet duct 220 and connect supply air duct 110 and air outlet duct 220, but also integrate the function of slide rail 340 that cooperates with drawer 800, integrating multiple functions into one, thereby simplifying the structure of refrigeration equipment 10 and making the overall structure more compact.

[0091] Please refer to Figures 5-7. In some embodiments, the transition duct 400 has an air inlet end 410 and an air outlet end 420. The air inlet end 410 is used to communicate with the supply air duct 110, and the air outlet end 420 is used to communicate with the outlet air duct 220. The cross-sectional width of the air inlet end 410 is greater than the cross-sectional width of the air outlet end 420.

[0092] The air inlet 410 and air outlet 420 can be respectively located at opposite ends of the transition duct 400. The cross-sectional width of the air inlet 410 is greater than that of the air outlet 420, that is, the cross-sectional width of the air inlet 410 is larger and the cross-sectional width of the air outlet 420 is smaller. The larger cross-sectional width of the air inlet 410 ensures that the cold air in the supply air duct 110 can fully enter the transition duct 400 when it connects with the supply air duct 110, so that the amount of cold air in the air outlet duct 220 is sufficient. The smaller cross-sectional width of the air outlet 420 allows the cold air to accelerate its flow rate when entering the air outlet duct 220 from the transition duct 400, thereby improving the air supply efficiency.

[0093] In some embodiments, the cross-sectional width of the transition duct 400 changes from wide to narrow along the direction from the supply air duct 110 to the outlet air duct 220.

[0094] The direction from the supply air duct 110 to the outlet air duct 220 is from bottom to top. It should be noted that the cross-sectional width of the transition air duct 400 changes from wide to narrow. That is, the cross-sectional width of the transition air duct 400 can gradually narrow from wide to narrow, or it can be narrowed in segments. That is, the cross-sectional width of a certain segment of the transition air duct 400 may be wider than the cross-sectional width of a certain segment below it, but the overall trend of the cross-section of the transition air duct 400 is from wide to narrow from bottom to top.

[0095] Since the cross-sectional width of the air inlet 410 is greater than that of the air outlet 420, the cross-sectional width of the transition duct 400 changes from wide to narrow, which can reduce airflow turbulence, reduce pressure loss, and improve the flow efficiency of cold air.

[0096] In some embodiments, along the direction from the supply air duct 110 to the outlet air duct 220, the transition air duct 400 has a plurality of sequentially arranged transition sections 430, with an arc transition between adjacent transition sections 430.

[0097] The arc transition between two adjacent transition sections 430 reduces sharp edges and lowers the obstruction of airflow by the inner wall of the air outlet duct 220, thereby reducing pressure loss and noise and making the gas flow smoother.

[0098] In some embodiments, along the direction from the supply air duct 110 to the outlet air duct 220, each transition section 430 includes at least a transition section 431 and a contraction section 432 arranged sequentially, and the cross-sectional width of the contraction section 432 changes from wide to narrow.

[0099] For ease of description, the two adjacent transition sections 430 are named the first transition section 430 and the second transition section 430, respectively. The second transition section 430 is above the first transition section 430. The contraction section 432 of the first transition section 430 is connected to the transition section 431 of the second transition section 430. Since the cross-sectional width of the contraction section 432 changes from wide to narrow, the width of the transition section 431 of the second transition section 430 is smaller than the width of the transition section 431 of the second transition section 430. And so on, so that the cross-sectional width of the transition duct 400 changes from wide to narrow.

[0100] A sudden change in the cross-sectional width of the transition duct 400 can lead to a significant increase in local pressure loss. In this embodiment, the cross-sectional width of the transition duct 400 does not gradually narrow, but rather narrows in segments. By keeping the cross-sectional width constant first and then gradually narrowing it, the abrupt change in gas velocity can be reduced, thereby reducing pressure loss along the flow path.

[0101] In some implementations, the variation trend of the cross-sectional width of the transition duct 300 is consistent with the variation trend of the cross-sectional width of the transition duct 400.

[0102] The cross-sectional width of the transition duct 400 changes from wide to narrow, which is also the trend of the cross-sectional width of the transfer duct 300. The transfer duct 300 needs to be used to insulate the transition duct 400 and reduce heat loss. Therefore, the transfer duct 300 has a certain thickness. The thickness of the transfer duct 300 refers to the length between the outer wall and the inner wall of the transfer duct 300. The inner wall of the transfer duct 300 is the inner wall of the transition duct 400.

[0103] The cross-sectional width of the transition duct 400 is related to the required thickness of the connecting duct 300. That is, the wider the cross-sectional width of the transition duct 400, the thicker the connecting duct 300 needs to be to meet insulation requirements. Similarly, the narrower the cross-sectional width of the transition duct 400, the thinner the connecting duct 300 needs to be. Therefore, the trend of the cross-sectional width of the connecting duct 300 is consistent with that of the transition duct 400. Specifically, the wider the cross-sectional width of the transition duct 400, the wider the cross-sectional width of the connecting duct 300, resulting in a thicker connecting duct 300. Conversely, the narrower the cross-sectional width of the transition duct 400, the narrower the cross-sectional width of the connecting duct 300, resulting in a thinner connecting duct 300. This ensures that the thickness of the connecting duct 300 matches the cross-sectional width of the transition duct 400.

[0104] In some embodiments, the refrigeration device 10 further includes a door 700, which is disposed at the opening of the chamber 140. The thickness of the door 700 is 25mm to 40mm, and the total thickness of the cabinet 100 and the door 700 is 450mm to 600mm.

[0105] Because the thickness of the door 700 is limited to 25mm to 40mm, the door 700 is relatively thin, making it easier for users to open and close the door. Because the total thickness of the cabinet 100 and the door 700 is limited to 450mm to 600mm, the overall thickness of the refrigeration equipment is relatively thin, which reduces the area occupied by the refrigeration equipment and makes it easier to move.

[0106] Specifically, the thickness of the door 700 can be 26mm, 30mm, 32mm, 36mm, or 38mm, and the total thickness of the box 100 and the door 700 can be 480mm, 520mm, 540mm, 560mm, or 580mm.
