[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] It should be noted that all directional indications in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0038] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited.

[0039] Furthermore, in this utility model, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0040] The refrigeration equipment has an air duct module that enables airflow within the equipment, allowing the cooled air to be blown onto the frozen items, thus freezing them. The air duct module also has an outlet air duct, through which air is supplied to the chambers of the refrigeration equipment.

[0041] The air duct module is located inside the refrigeration unit. In related technologies, when the air duct is damaged, repair personnel need to disassemble the air duct module and surrounding components. This makes the repair process technically challenging and requires significant manpower, resources, and time. Furthermore, the lengthy repair cycle may render the refrigerator unusable for an extended period, disrupting the user's daily life.

[0042] To address the problems existing in related technologies to some extent, this application provides a duct module refrigeration device. When repairing the air outlet duct, it is not necessary to disassemble the duct module and its surrounding components, which greatly saves manpower, material resources and time costs and shortens the maintenance cycle.

[0043] This application is described below with reference to the accompanying drawings and specific embodiments:

[0044] Please see Figure 1 This application provides an air duct module 200, which is installed in the chamber 140 of the refrigeration equipment 10. When maintaining the air outlet duct 220, it is not necessary to disassemble the air duct module 200 and its surrounding related components, thereby greatly saving manpower, material resources and time costs and shortening the maintenance cycle.

[0045] 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.

[0046] 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.

[0047] Similarly, for ease of description, six directions are defined: up, down, left, right, front, and back. In the height direction Z, the direction closer to the top surface is up, and the direction further from the top surface is down. In the width direction X, the two directions are left and right. The chamber 140 of the refrigeration device 10 has an opening, and a door 700 is provided at the opening. In the thickness direction Y, the direction closer to the door 700 is front, and the direction further from the door 700 is back.

[0048] Please see Figure 1 and Figure 2 In this embodiment, the air duct module 200 includes a housing 210 and a transition assembly 300. An air outlet duct 220 is disposed within the housing 210; the housing 210 has an inspection window 230; the transition assembly 300 includes a cover plate 310 and a mounting member 320 mounted on the cover plate 310, the mounting member 320 having a transition duct 325 communicating with the air outlet duct 220.

[0049] The adapter component 300 is installed in the inspection window 230, and the cover plate 310 is detachably connected to the housing 210.

[0050] Please see Figures 3-5 The housing 210 is the main structure of the entire air duct module 200, providing a mounting base for the outlet air duct 220, which supplies air to the chamber 140 of the refrigeration equipment 10. The refrigeration equipment 10 includes an evaporator 120 and a guide element 130. The evaporator 120 is used to cool the air, and the guide element 130 is used to circulate the cold air within the chamber 140 to cool the items. Specifically, the housing 210 has an air outlet 221 and a return air outlet 222 communicating with the outlet air duct 220. The guide element 130 allows gas in the chamber 140 to enter the outlet air duct 220 through the return air outlet 222, and gas in the outlet air duct 220 to flow from the air outlet 221 back into the chamber 140. The evaporator 120 and the guide element 130 can be installed in the outlet air duct 220 or in other air ducts of the refrigeration equipment 10; there are no restrictions on this.

[0051] The housing 210 has an inspection window 230. The adapter assembly 300 is installed in the inspection window 230. The adapter assembly 300 includes a cover plate 310 and a mounting member 320 installed on the cover plate 310. The cover plate 310 is detachably connected to the housing 210. Therefore, by separating the cover plate 310 and the housing 210, the adapter assembly 300 can be removed from the inspection window 230. Since the mounting member 320 has a transition air duct 325 that communicates with the air outlet duct 220, after the mounting member 320 is removed from the inspection window 230, the air outlet duct 220 will be exposed in the inspection window 230, so that maintenance personnel can perform maintenance on the air outlet duct 220.

[0052] The adapter component 300 can be regarded as a detachable part of the air duct module 200. When the outlet air duct 220 needs maintenance, the cover plate 310 and the housing 210 are separated, and the adapter component 300 is removed from the maintenance window 230. The outlet air duct 220 can then be maintained through the maintenance window 230. After the outlet air duct 220 is maintained, the adapter component 300 is reinstalled to the maintenance window 230, and the cover plate 310 and the housing 210 are connected so that the transition air duct 325 is connected to the outlet air duct 220. The entire process does not require disassembling the housing 210 and its surrounding components, which greatly saves manpower, material resources and time costs and shortens the maintenance cycle.

[0053] Please see Figure 4 In some embodiments, the housing 210 has a fixing surface 211, the cover plate 310 and the fixing surface 211 form a fixing cavity 311, and the mounting member 320 is located in the fixing cavity 311.

[0054] Since the transition duct 325 is connected to the outlet duct 220, cold air will pass through the transition duct 325. In order to reduce the amount of cold air lost when passing through the transition duct 325, at least part of the mounting component 320 needs to be made of thermal insulation material, that is, at least both sides of the transition duct 325 need to be made of thermal insulation material. Specifically, at least part of the mounting component 320 can be made of foam.

[0055] Since at least part of the mounting component 320 is made of foam material, its structure is relatively fragile. Therefore, the mounting component 320 needs to be protected to avoid damage as much as possible, which would affect the thermal insulation effect. Because the air duct module 200 has a fixing surface 211, the cover plate 310 and the fixing surface 211 form a fixing cavity 311, and the mounting component 320 is located in the fixing cavity 311, thus the fixing cavity 311 can protect the mounting component 320.

[0056] Specifically, the cover plate 310 and the fixing surface 211 can be respectively disposed on the left and right sides of the mounting component 320. The cover plate 310 and the fixing surface 211, together with the front and rear inner walls of the inspection window 230, protect the periphery of the mounting component 320.

[0057] Please see Figures 6-8 In some embodiments, the air duct module 200 further includes a fixing member 313, the housing 210 is provided with a first fixing hole 212, the cover plate 310 is provided with a second fixing hole 312, and the fixing member 313 passes through the first fixing hole 212 and the second fixing hole 312.

[0058] The fastener 313 passes through the first fixing hole 212 and the second fixing hole 312, so that the cover plate 310 is connected to the air duct module 200. Of course, the fastener 313 can be detachably installed in the first fixing hole 212 and the second fixing hole 312. When it is necessary to separate the cover plate 310 and the air duct module 200, the fastener 313 can be removed from the first fixing hole 212 and the second fixing hole 312.

[0059] Specifically, the fastener 313 can be a bolt, and the first fixing hole 212 and the second fixing hole 312 can be screw holes. The fastener 313 is screwed into the first fixing hole 212 and the second fixing hole 312, thereby realizing the connection of the cover plate 310 to the air duct module 200.

[0060] Please see Figure 9 In some embodiments, one end of the cover plate 310 has a connecting plate 314, the connecting member includes a fixing part 314a and an overlapping part 314b arranged at an angle, a second fixing hole 312 is provided in the fixing part 314a, and an overlapping member 213 is provided on the side of the housing 210, the overlapping part 314b overlaps the overlapping member 213.

[0061] Since the adapter assembly 300 is detachably installed in the inspection window 230, it needs to be repeatedly disassembled and installed whenever the outlet air duct 220 needs maintenance. If the transition air duct 325 and the outlet air duct 220 are not perfectly aligned during installation, resulting in misalignment, the air supply efficiency will be affected. Therefore, the adapter assembly 300 needs to be positioned correctly during installation.

[0062] A connecting plate 314 is disposed at one end of the cover plate 310 along the height direction. Since the cover plate 310 has an overlapping portion 314b, and the side of the housing 210 is provided with an overlapping member 213, and the overlapping portion 314b overlaps with the overlapping member 213, when installing the adapter assembly 300, the overlapping portion 314b is first overlapped with the overlapping member 213, and then the housing 210 and the cover plate 310 are connected by the fixing member 313, so that the transition air duct 325 is aligned with the outlet air duct 220 as much as possible. Since the fixing portion 314a and the overlapping portion 314b are arranged at an angle, the connecting function and the overlapping function of the connector do not interfere with each other.

[0063] Specifically, the fixing part 314a and the overlapping part 314b can be arranged vertically, with the fixing part 314a arranged along the height direction and the overlapping part 314b arranged along the width direction. The overlapping part 314b is located above the overlapping member 213, and the fixing part 314a is located on the side of the overlapping part 314b away from the overlapping member 213, so as to avoid the overlapping member 213.

[0064] In some embodiments, the first fixing hole 212 is offset from the overlapping member 213.

[0065] Since the connector includes a fixing part 314a and an overlapping part 314b, the fixing part 314a is connected to the housing 210, and the overlapping part 314b overlaps with the overlapping member 213. The fixing part 314a and the overlapping part 314b are arranged at an angle, so that the fixing part 314a and the overlapping part 314b do not interfere with each other. In order to ensure that the first fixing hole 212 and the overlapping member 213 also do not interfere with each other, the first fixing hole 212 and the overlapping member 213 are staggered.

[0066] Specifically, the overlapping member 213 is arranged along the thickness direction, and there are two fixing members 313, so there are also two first fixing holes 212, and the overlapping member 213 is arranged between the two fixing holes.

[0067] In some embodiments, the other end of the cover plate 310 has a support plate 315, which is supported on the mounting member 320.

[0068] The other end of the cover plate 310 is the other end of the cover plate 310 along the height direction. Since the cover plate 310 and the mounting part 320 are two separate structures, the overlapping action of the overlapping part 314b and the overlapping part 213 ensures that the cover plate 310 is accurately positioned. This keeps the relative position of the mounting part 320 and the cover plate 310 fixed, ensuring that the transition duct 325 is aligned with the outlet duct 220 after the adapter assembly 300 is installed. A support plate 315 is provided at the other end of the cover plate 310, supporting the mounting part 320. This makes the mounting part 320 more securely installed on the cover plate 310, reducing positional changes of the mounting part 320 relative to the cover plate 310. This ensures that after the cover plate 310 is positioned, the transition duct 325 of the mounting part 320 can be aligned with the outlet duct 220.

[0069] Please see Figure 4 and Figure 12 In some embodiments, the mounting component 320 includes a mounting body 322 and a fixing plate 323 disposed on the outer surface of the mounting body 322, a transition air duct 325 disposed on the mounting body 322, and a cover plate 310 detachably connected to the fixing plate 323.

[0070] Since the transition duct 325 is located on the mounting body 322, the mounting body 322 is made of foam to achieve the function of heat insulation for the transition duct 325. However, since it is difficult to make rigid connections with foam material, a fixing plate 323 is provided on the outer surface of the mounting body 322. At least part of the fixing plate 323 is arranged opposite to the cover plate 310, and the cover plate 310 and the fixing plate 323 are connected, that is, the cover plate 310 and the fixing plate 323 jointly clamp and fix the mounting member 320, so that the mounting member 320 is installed on the cover plate 310.

[0071] After long-term use, the thermal insulation performance of the mounting body 322 will decrease. Since the cover plate 310 and the fixing plate 323 are detachably connected, when the mounting body 322 needs to be replaced, the cover plate 310 and the fixing plate 323 can be removed.

[0072] Based on the same inventive concept, please refer to Figures 1-3 This application embodiment also provides a refrigeration device 10 including a housing 100 and the aforementioned air duct module 200. The housing 100 includes a chamber 140 for containing items, the air duct module 200 is installed in the housing 100, and an air outlet duct 220 is used to supply air into the chamber 140. The refrigeration device 10 provided in this application embodiment has the same beneficial effects as the aforementioned air duct module 200, and will not be described again here.

[0073] The housing 100 is the main structure of the entire refrigeration equipment 10. It provides a mounting base for structures such as the air duct module 200, compressor, and evaporator 120, and also protects the aforementioned electronic components. The chamber 140 is used to hold items to be refrigerated or frozen, and the cold air blown out by the air outlet duct 220 is used to refrigerate or freeze the items.

[0074] The housing 100 also includes an air supply duct 110. The refrigeration unit 10's chamber 140 includes a freezing chamber 142 and a refrigeration chamber 141. The air supply duct 110 supplies air to the freezing chamber 142, and the air outlet duct 220 supplies air to the refrigeration chamber 141. The evaporator 120 and the air guide 130 can be installed in the air supply duct 110. The air supply duct 110 is connected to the air outlet duct 220, allowing cold air from the air supply duct 110 to enter the air outlet duct 220 for cooling the refrigeration chamber. The transition duct 325 of the adapter assembly 300 can simultaneously connect the air outlet duct 220 and the air supply duct 110, meaning cold air from the air supply duct 110 can enter the air outlet duct 220 via the transition duct 325. Of course, since the evaporator 120 is located in the air supply duct 110, the return air port 222 of the air duct module 200 is connected to the air supply duct 110, and the returning air enters the air supply duct 110 through the return air port 222.

[0075] The cabinet 100 may have a partition inside, which is used to divide the refrigeration chamber 141 and the freezing chamber 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 refrigeration chamber 141 and the freezing chamber 142 have partitions, and the air supply duct 110 and the air outlet duct 220 can be located inside the partitions, that is, the partition in the refrigeration chamber 141 is configured as the shell 210 of the air duct module 200. By carrying and accommodating the air supply duct 110 and the air outlet duct 220 through the partition, the internal space of the partition can be effectively utilized, reducing the space occupied by the air ducts on the external space, making the overall structure more compact.

[0076] Please see Figure 7 In some embodiments, the refrigeration device 10 also includes a drawer 500, which is installed in the chamber 140. The cover plate 310 is provided with a slide rail 316 on the side facing the chamber 140, and the drawer 500 slides in conjunction with the slide rail 316.

[0077] Drawer 500 is used to place items. Chamber 140 has an opening, through which drawer 500 can slide into or out of chamber 140 to retrieve items. Since the partition is configured as the housing 210 of the air duct module 200, the adapter assembly 300 is also located within the partition, meaning the adapter assembly 300 is also part of chamber 140. In this embodiment, utilizing the location of the adapter assembly 300, a slide rail 316 is provided on the side of the cover plate 310 facing chamber 140. Drawer 500 slides in conjunction with slide rail 316, thereby realizing the sliding function of drawer 500. In other words, adapter assembly 300 can not only be used for maintenance of air outlet duct 220 and connecting air supply duct 110 and air outlet duct 220, but also integrates the function of slide rail 316 that cooperates with drawer 500, integrating multiple functions into one, thereby simplifying the structure of refrigeration equipment 10 and making the overall structure more compact.

[0078] Furthermore, since the adapter component 300 is detachable, it is convenient to repair the slide rail 316 when it malfunctions.

[0079] Please see Figure 4 In some embodiments, the refrigeration equipment 10 further includes a damper assembly 400, which is installed on the housing 100. The housing 100 is provided with an air vent 161. The damper assembly 400 can open or close the air vent 161. When the cover plate 310 is removed, the damper assembly 400 can be exposed to the maintenance window 230 through the air vent 161.

[0080] The damper assembly 400 can connect or separate the supply air duct 110 and the outlet air duct 220, and adjust the airflow of the duct, by opening or closing the air outlet 161. The damper assembly 400 can open or close the air outlet 161 by rotating it. When the damper assembly 400 opens the air outlet 161, the air outlet 161 connects the supply air duct 110 and the outlet air duct 220, and the cold air in the supply air duct 110 enters the outlet air duct 220 through the air outlet 161. When the damper assembly 400 closes the air outlet 161, that is, when the damper assembly 400 covers the air outlet 161, the supply air duct 110 and the outlet air duct 220 are separated.

[0081] The damper assembly 400 is also a component that is relatively prone to failure. Since the damper assembly 400 can be exposed to the maintenance window 230 through the air vent 161 when the cover plate 310 is removed, that is, when the adapter assembly 300 is removed from the maintenance window 230, the air vent 161 will be exposed in the maintenance window 230, and the damper assembly 400 will be exposed in the air vent 161. Thus, maintenance personnel can perform maintenance on the damper assembly 400 through the air vent 161 without disassembling the air duct module 200 and its surrounding related components, which greatly saves manpower, material resources and time costs and shortens the maintenance cycle.

[0082] In some embodiments, the housing 100 includes a main body 150 and a mounting part 160. The air duct module 200 is mounted on the main body 150, the mounting part 160 is detachably mounted on the main body 150 and located below the inspection window 230, the air outlet 161 is disposed on the mounting part 160, and the damper assembly 400 is mounted on the side of the mounting part 160 away from the inspection window 230.

[0083] The mounting part 160 can be located at the end of the supply air duct 110 near the outlet air duct 220. The bottom of the adapter assembly 300 can contact the mounting part 160, and the mounting part 160 separates the outlet air duct 220 and the supply air duct 110. Depending on the damage to the damper assembly 400, it may be necessary to remove the damper assembly 400 from the housing 100 for easier maintenance. Since the mounting part 160 is detachably mounted on the main body 150 and the damper assembly 400 is mounted on the mounting part 160, when the damper assembly 400 needs to be inspected, the mounting part 160 can be directly removed from the main body 150, thereby removing the damper assembly 400 from the housing 100 for maintenance.

[0084] Specifically, the partition plate has a fixing groove 162 on the side away from the inspection window 230, and the damper assembly 400 is installed in the fixing groove 162 to facilitate the installation or removal of the damper assembly 400. The partition plate can be connected to the main body 150 by bolts to ensure the fixing effect.

[0085] It should be noted that the air duct module 200 can have more than one air outlet duct 220. Of course, the air outlet duct 220, the transition air duct 325, and the air outlet 161 are all set in a one-to-one correspondence. When there is more than one air outlet 161, the damper assembly 400 also includes more than one damper.

[0086] Please see Figure 10 and Figure 11 In some embodiments, a connecting member 163 is provided at the air outlet 161, and a connecting groove 321 is provided on the mounting member 320. The connecting member 163 is connected to the connecting groove 321 so that the transition air duct 325 is aligned with the air outlet 161.

[0087] Since the adapter component 300 is detachably installed in the maintenance window 230, it needs to be repeatedly disassembled and reinstalled whenever the damper component 400 needs maintenance. If the transition duct 325 and the air outlet 161 are not fully aligned during installation, resulting in misalignment, the air supply efficiency will be affected. Therefore, a connecting piece 163 is provided at the air outlet 161, and a connecting groove 321 is provided on the mounting component 320. The connecting piece 163 connects to the connecting groove 321, so that the transition duct 325 is aligned with the air outlet 161, allowing the cold air in the air supply duct 110 to fully pass through the air outlet 161 into the transition duct 325, thus ensuring air supply efficiency. Furthermore, since the position of the duct module 200 remains fixed, the transition duct 325 aligned with the air outlet 161 is also aligned with the outlet duct 220. Specifically, since the air outlet 161 is located in the mounting part 160, the connecting piece 163 is also located in the mounting part 160.

[0088] Since the adapter component 300 is located above the air outlet 161, the connecting piece 163 is located on the upper part of the air outlet 161, and the connecting groove 321 is located at the bottom of the mounting piece 320. When installing the adapter component 300, the connecting piece 163 is connected to the connecting groove 321, so that the transition air duct 325 is aligned with the air outlet 161.

[0089] Of course, in other embodiments, the air duct module 200 may be provided with a docking part 163, the mounting part 320 may be provided with a docking groove 321, and the docking part 163 may dock with the docking groove 321 so that the transition air duct 325 is aligned with the outlet air duct 220. There are no restrictions on this.

[0090] Please see Figure 1 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.

[0091] 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.

[0092] 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.
