After the air outlet duct is repaired, the adapter component can be reinstalled into the inspection window. The whole process does not require disassembling the housing and its surrounding components, thereby greatly saving manpower, material resources and time costs, and shortening the maintenance cycle.

[0035] 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.

[0036] 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.

[0037] 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.

[0038] 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.

[0039] 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.

[0040] 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.

[0041] To address the problems existing in related technologies to some extent, this application provides an air duct module and a refrigeration device. When repairing the air outlet duct, it is not necessary to disassemble the air duct module and its surrounding components, which greatly saves manpower, material resources and time costs and shortens the maintenance cycle.

[0042] This application is described below with reference to the accompanying drawings and specific embodiments:

[0043] Please see Figure 1 and Figure 2 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.

[0044] 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.

[0045] 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.

[0046] 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.

[0047] Please see Figures 3-5 In this embodiment, the air duct module 200 includes a housing 210 and a connecting component 300. An air outlet duct 220 is provided inside the housing 210, and the housing 210 has an inspection window 230; the connecting component 300 is installed in the inspection window 230 and is detachably connected to the housing 210.

[0048] The adapter component 300 has a first guide slope 324, and the inspection window 230 has a second guide slope 231. The first guide slope 324 is in contact with the second guide slope 231.

[0049] Please see Figures 4-6 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.

[0050] 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.

[0051] 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.

[0052] The adapter assembly 300 has a first guide slope 324, and the inspection window 230 has a second guide slope 231. The second guide slope 231 is located on the inner wall of the inspection window 230. The first guide slope 324 contacts the second guide slope 231, ensuring a tight fit between the adapter assembly 300 and the housing 210. This maximizes the integrity of the duct module 200's appearance and minimizes the exposure of the inspection window 230. During installation of the adapter assembly 300, the first guide slope 324 and the second guide slope 231 slide against each other, providing guidance for the installation of the adapter assembly 300. This ensures more accurate positioning and smoother installation.

[0053] In some embodiments, the inclination angle of the first guide ramp 324 and the second guide ramp 231 is 30° to 45°.

[0054] The inclination angle of the first guide slope 324 and the second guide slope 231 is the angle between them and the horizontal plane. It is understood that the inclination angles of the first guide slope 324 and the second guide slope 231 are the same. If the inclination angle of the first guide slope 324 and the second guide slope 231 is too small, the guiding effect will be insignificant. If the inclination angle of the first guide slope 324 and the second guide slope 231 is too large, the size of the inspection window 230 will be too large, affecting the function of the air outlet duct 220. Therefore, in this embodiment, the inclination angle of the first guide slope 324 and the second guide slope 231 is limited to 30° to 45°.

[0055] Specifically, the inclination angles of the first guide slope 324 and the second guide slope 231 can be 33°, 36°, 39°, 42°, and 44°.

[0056] Please see Figure 4 In some embodiments, the adapter assembly 300 includes a cover plate 310 and a mounting member 320 mounted on the cover plate 310. The cover plate 310 is detachably connected to the housing 210, and a first guide ramp 324 is disposed on the mounting member 320.

[0057] Since the mounting component 320 is installed on the cover plate 310, and the cover plate 310 is detachably connected to the housing 210, when the adapter assembly 300 needs to be disassembled, the cover plate 310 is separated from the housing 210, and the adapter assembly 300 can be removed from the inspection window 230. Similarly, when the adapter assembly 300 needs to be installed, the adapter assembly 300 is first installed in the inspection window 230, and then the cover plate 310 is connected to the housing 210.

[0058] Please see Figure 4 In some embodiments, the mounting component 320 has a transition duct 325 that communicates with the outlet duct 220.

[0059] Since the adapter component 300 occupies the height space of the housing 210, in order to minimize the reduction of the length of the air outlet duct 220, a transition duct 325 can be set in the mounting component 320 to connect with the air outlet duct 220. The transition duct 325 can be regarded as an extension of the air outlet duct 220 or a part of the air outlet duct 220, so that the cold air will also flow in the transition duct 325.

[0060] Since 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.

[0061] It should be noted that since the adapter component 300 is detachably installed in the inspection window 230, the adapter component 300 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 completely aligned during the installation of the adapter component 300, resulting in misalignment, the air supply efficiency will be affected. However, since the adapter component 300 has a first guide slope 324 and the inspection window 230 has a second guide slope 231, the first guide slope 324 and the second guide slope 231 will slide and engage during the installation of the adapter component 300, thereby providing a certain guide for the installation of the adapter component 300, making the installation positioning of the adapter component 300 more accurate, and thus making the alignment between the transition air duct 325 and the outlet air duct 220 more accurate.

[0062] 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.

[0063] 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.

[0064] Specifically, the maintenance window 230 can be located at the lower end of the housing 210, thereby the transition assembly 300 is located at the lower end of the housing 210. It can be understood that since the air duct module 200 provides air outlet from the top and air return from the bottom to achieve gas circulation within the chamber 140 of the refrigeration equipment 10, and the maintenance window 230 is located at the lower end of the air duct module 200, and the transition air duct 325 connects to the outlet air duct 220, the return air vent 222 can be located on the cover plate 310. Since the return air needs to be cooled by the evaporator 120, and the evaporator 120 and the air intake 130 are located in the supply air duct 110, the housing 100 is provided with a return air duct connected to the supply air duct 110. The return air inlet 222 is connected to the return air duct, so that air can enter the supply air duct 110 through the return air inlet 222 and the return air duct, be cooled by the evaporator 120, and then enter the supply air duct 110 to achieve gas circulation. Specifically, the return air duct is located in the partition 160, that is, the partition 160 is an integrated supply and return air structure. The cold air in the supply air duct 110 enters the outlet air duct 220 through the air inlet 161, and the hot air enters the supply air duct 110 through the return air duct.

[0065] Please see Figure 7 and Figure 8In 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, a cover plate 310 detachably connected to the fixing plate 323, and a first guide slope 324 disposed on the fixing plate 323.

[0066] 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.

[0067] 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.

[0068] In some embodiments, the fixed plate 323 is provided with a connecting port 323a, which is used to connect the transition air duct 325 and the outlet air duct 220.

[0069] Since the first guide slope 324 is provided on the fixed plate 323, and the first guide slope 324 needs to contact the second guide slope 231 to connect the transition air duct 325 and the outlet air duct 220, a connecting port 323a is provided on the fixed plate 323. The connecting port 323a is correspondingly provided with the transition air duct 325 and the outlet air duct 220. Thus, when the first guide slope 324 needs to contact the second guide slope 231, the connecting port 323a connects the transition air duct 325 and the outlet air duct 220.

[0070] Please see Figure 9 In some embodiments, the adapter assembly 300 further includes a seal 330, at least a portion of which is attached to the first guide ramp 324.

[0071] Since the air outlet duct 220 and the transition duct 325 are connected through the contact of the first guide slope 324 and the second guide slope 231, a seal 330 needs to be installed between the first guide slope 324 and the second guide slope 231 to reduce cold air leakage. Furthermore, the beveled fit between the adapter assembly 300 and the housing 210 itself makes the contact between the adapter assembly 300 and the housing 210 tighter, resulting in better sealing and thus reducing cold air leakage.

[0072] At least a portion of the seal 330 is abutted against the first guide slope 324. This can mean that the entire seal is abutted against the first guide slope 324, or that a portion of the seal 330 is abutted against the first guide slope 324 and another portion is abutted against other surfaces of the adapter assembly 300. Once the adapter assembly 300 is in place, the seal 330 is positioned between the first guide slope 324 and the second guide slope 231 to provide a seal.

[0073] Specifically, the seal 330 can be made of PU sponge, and the thickness of the seal 330 can be 2mm to 4mm.

[0074] In some embodiments, the adapter 300 is rotatable relative to the housing 210, such that the first guide ramp 324 contacts the second guide ramp 231.

[0075] Since the first guide slope 324 is provided with a sealing element 330, when installing the adapter assembly 300, if the adapter assembly 300 is directly pushed into the maintenance window 230, the sealing element 330 is easily squeezed by the second guide slope 231, affecting the sealing effect. Therefore, the adapter assembly 300 can be installed in the maintenance window 230 by rotation.

[0076] Specifically, with Figure 4 Taking the orientation as an example, the first guide slope 324 and the second guide slope 231 are inclined downward from left to right. When installing the adapter component 300, the adapter component 300 is first positioned on the left side of the inspection window 230, then the adapter component 300 is tilted to the left, and finally the adapter component 300 is rotated clockwise into the inspection window 230. During this process, the seal 330 will not be in contact with the second guide slope 231 throughout the process, so it will not be squeezed by the second guide slope 231. The seal 330 will only be squeezed after the adapter component 300 is fully installed, thereby reducing the deformation of the seal 330 and ensuring the sealing effect.

[0077] Based on the same inventive concept, please refer to Figure 1 and Figure 2 This application provides a refrigeration device 10, including a housing 100 and the aforementioned 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 an air outlet duct 220 is used to supply air into the chamber 140. The refrigeration device 10 provided in this application has the same beneficial effects as the aforementioned air duct module 200, and will not be described again here.

[0078] 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.

[0079] 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.

[0080] 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.

[0081] Please see Figure 10 and Figure 11 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.

[0082] 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.

[0083] Furthermore, since the adapter component 300 is detachable, it is convenient to repair the slide rail 316 when it malfunctions.

[0084] 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.

[0085] The damper assembly 400 can connect or separate the supply air duct 110 and the outlet air duct 220 by opening or closing the air vent 161, and can also adjust the air volume of the air vent 161. The damper assembly 400 can open or close the air vent 161 by rotating it. When the damper assembly 400 opens the air vent 161, the air vent 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 vent 161. When the damper assembly 400 closes the air vent 161, that is, when the damper assembly 400 covers the air vent 161, the supply air duct 110 and the outlet air duct 220 are separated.

[0086] 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.

[0087] 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.

[0088] In some embodiments, the housing 100 includes a main body 150 and a partition 160, an air duct module 200 is mounted on the main body 150, the partition 160 is detachably mounted on the main body 150 and located below the access window 230, an air vent 161 is disposed on the partition 160, and an air damper assembly 400 is mounted on the side of the partition 160 away from the access window 230.

[0089] The separator 160 can be located at the end of the supply air duct 110 near the outlet air duct 220, and the bottom of the adapter assembly 300 can contact the separator 160, which 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 separator 160 is detachably installed on the main body 150 and the damper assembly 400 is installed on the separator 160, when the damper assembly 400 needs to be inspected, the separator 160 can be directly removed from the main body 150, thereby removing the damper assembly 400 from the housing 100 for maintenance.

[0090] 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.

[0091] 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.

[0092] 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.

[0093] 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.
