Description

Technical Field

[0001] This application belongs to the field of household appliance technology, and in particular relates to a refrigeration device. Background Technology

[0002] The refrigeration equipment has multiple air duct modules to supply air to different chambers. These modules are interconnected to facilitate the transfer of cold air, allowing a single refrigeration unit to supply air to multiple chambers. The equipment also includes dampers to regulate the airflow between the air duct modules.

[0003] Because the dampers are located inside the refrigeration equipment's casing, in related technologies, when a damper is damaged, maintenance 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 refrigeration equipment unusable for an extended period, disrupting users' daily lives. Summary of the Invention

Detailed Implementation

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0036] It should be noted that all directional indications in the embodiments of the present invention are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0037] In this invention, unless otherwise explicitly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" 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. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0038] Furthermore, in this invention, 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 invention.

[0039] The refrigeration equipment has multiple air duct modules to supply air to different chambers. These multiple air duct modules can be connected or separated by opening and closing dampers. When multiple air duct modules are connected, cold air can be transferred, thus enabling one set of refrigeration components to supply air to multiple chambers.

[0040] Because the damper is located inside the refrigeration unit, in related technologies, when the damper 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 a refrigeration device that eliminates the need to disassemble the air duct module and its surrounding components when repairing the damper assembly, thus greatly saving manpower, material resources, and time costs and shortening 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 a refrigeration device 10 that eliminates the need to disassemble the air duct module and its surrounding components when repairing the damper, 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 depth 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 depth 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 of the refrigeration device 10 has an opening, and a door 800 is provided at the opening. In the depth direction Y, the direction closer to the door 800 is front, and the direction further from the door 800 is back.

[0047] Please see Figures 2-7 In this embodiment, the refrigeration equipment 10 includes a housing 100, a first air duct module 200, and an air damper assembly 400. The housing 100 has a refrigerator compartment 140. The first air duct module 200 is installed in the housing 100. The first air duct module 200 includes a housing 210, a connecting assembly 250, and an air duct assembly 200a. At least a portion of the air duct assembly 200a is disposed within the housing 210. The air duct assembly 200a is used to supply air to the refrigerator compartment 140. The housing 210 has an inspection window 240, and the connecting assembly 250 is detachably installed in the inspection window 240. The air damper assembly 400 is installed in the housing 100 and is used to connect or separate the air duct assembly 200a from the air supply duct 610.

[0048] When the adapter assembly 250 is removed, the damper assembly 400 can be exposed through the inspection window 240.

[0049] The housing 100 forms the basic structure of the refrigeration equipment 10, providing installation and protection for at least some of the other components of the refrigeration equipment 10. The cold storage compartment 140 is used to hold items, and the air duct assembly 200a is used to supply air to the cold storage compartment 140, thereby refrigerating the items in the cold storage compartment 140. At least a portion of the air duct assembly 200a is installed within the housing 210; that is, either the entire air duct assembly 200a is installed within the housing 210, or only a portion of the air duct assembly 200a is installed within the housing 210.

[0050] The damper assembly 400 is installed on the housing 100 and is used to connect or separate the air duct assembly 200a and the supply air duct 610. That is, when the air duct assembly 200a and the supply air duct 610 are connected, cold air in the supply air duct 610 can enter the air duct assembly 200a to cool the items in the refrigerator compartment 140. The damper assembly 400 can be opened or closed to connect or separate the first air inlet 223 and the second air inlet 233, and the air volume can be adjusted by adjusting the opening degree of the damper assembly 400.

[0051] The housing 210 has an inspection window 240, and the adapter assembly 250 is detachably installed in the inspection window 240. When the adapter assembly 250 is removed, the damper assembly 400 can be exposed in the inspection window 240. That is, when the adapter assembly 250 is installed in the inspection window 240, the damper assembly 400 is covered by the adapter assembly 250; when the adapter assembly 250 is removed from the inspection window 240, the damper assembly 400 is exposed. Therefore, when the damper assembly 400 is damaged, the adapter assembly 250 can be removed from the inspection window 240, allowing the damper assembly 400 to be viewed and repaired through the inspection window 240. After the damper assembly 400 is repaired, the adapter assembly 250 can be reinstalled in the inspection window 240. This process does not require disassembling the duct module and its surrounding components, greatly saving manpower, material resources, and time costs, and shortening the maintenance cycle.

[0052] In some embodiments, a first air duct module 200 is installed in the refrigerator compartment 140, dividing the refrigerator compartment 140 into a first chamber 141 and a second chamber 142; the air duct assembly 200a includes a first air duct 220 and a second air duct 230; the first air duct 220 has a first air inlet 223 and a first air outlet 224 communicating with the first chamber 141, and the second air duct 230 has a second air inlet 233 and a second air outlet 234 communicating with the second chamber 142; and a damper assembly 400 is used to connect or separate the first air inlet 223, the second air inlet 233 and the air supply duct 610.

[0053] Since the first air duct module 200 is installed in the refrigerator compartment 140, and the first air duct module 200 divides the refrigerator compartment 140 into a first chamber 141 and a second chamber 142, the first air duct module 200 integrates both air outlet and partition functions, reducing the space occupied by the air ducts and making the overall structure more compact. Specifically, the refrigerator compartment 140 has a middle partition, which is configured as the shell 210 of the first air duct module 200. By supporting and accommodating the first air duct 220 and the second air duct 230 through the middle partition, the internal space of the middle partition can be effectively utilized. When the refrigerator compartment 140 is divided into two or more independent compartments, different types of food, such as vegetables, fruits, and dairy products, can be better classified and stored, making it easier to manage and maintain the optimal freshness of the food.

[0054] The first air duct 220 has a first air outlet 224 and a first air inlet 223. When cooling the first chamber 141, cold air can be discharged sequentially through the first air inlet 223, the first air duct 220, and the first air outlet 224. The second air duct 230 has a second air outlet 234 and a second air inlet 233. When cooling the second chamber 142, cold air can be discharged sequentially through the second air inlet 233, the second air duct 230, and the second air outlet 234.

[0055] The first air inlet 223 is located below the first air outlet 224, and the second air inlet 233 is located below the second air outlet 234. This means that the first air outlet 224 is higher than the first air inlet 223, and the second air outlet 234 is higher than the second air inlet 233, achieving a "bottom-in, top-out" cooling effect. Since cold air is denser than hot air, after the cold air is discharged from the first air outlet 224 and / or the second air outlet 234, it naturally sinks. During this descent, the cold air effectively cools items within the space connected to the first air outlet 224 and / or the second air outlet 234, creating a uniform temperature distribution throughout the space. This reduces temperature stratification, allowing food or items within the cavity to be cooled evenly, improving cooling efficiency. The uniform temperature distribution also helps extend the shelf life of food, reduces the risk of food spoilage due to temperature fluctuations, and enhances the user experience.

[0056] The damper assembly 400 is used to connect or separate the first air inlet 223, the second air inlet 233, and the air supply duct 610. Specifically, when the first air inlet 223 and the second air inlet 233 are connected to the air supply duct 610, the cold air in the air supply duct 610 enters the first air duct 220 and the second air duct 230 respectively through the first air inlet 223 and the second air inlet 233. The damper assembly 400 can connect or separate the first air inlet 223 and the second air inlet 233 by opening or closing, and the airflow can be adjusted by changing the opening degree of the damper assembly 400. Of course, the damper assembly 400 includes two dampers, one for each of the first air inlet 223 and the second air inlet 233.

[0057] It should be noted that since the structure and principle of the first air duct 220 and the second air duct 230 are completely the same, this article will mainly describe the first air duct 220, and the same applies to the second air duct 230.

[0058] Please see Figures 3-5 In some embodiments, the first air duct 220 includes a first air outlet duct 221 and a first transfer duct 222, and the second air duct 230 includes a second air outlet duct 231 and a second transfer duct 232. The first air outlet duct 221 and the second air outlet duct 231 are disposed within the housing 210, and the first transfer duct 222 and the second transfer duct 232 are disposed within the transfer assembly 250.

[0059] Since the adapter assembly 250 occupies a certain space in the height direction of the housing 210, if the first air duct 220 and the second air duct 230 were both located entirely within the housing 210, the height of the first air duct 220 would be shortened, thus reducing the cooling range within the first chamber 141 and the second chamber 142. Therefore, part of the first air duct 220 is located within the housing 210, and the remainder is located within the adapter assembly 250. When the adapter assembly 250 is installed in the maintenance window 240, the first adapter air duct 222 is aligned with and connected to the first outlet air duct 221 to form the first air duct 220, and the second adapter air duct 232 is aligned with and connected to the second outlet air duct 231 to form the second air duct 230, thus not affecting the air outlet range of the first air duct 220 and the second air duct 230.

[0060] Of course, the size of the adapter component 250 is much smaller than the size of the housing 210, and the length of the first adapter air duct 222 is much smaller than the length of the first air outlet air duct 221, so that the adapter component 250 can be easily disassembled.

[0061] Please see Figures 3-5 In some embodiments, the first air outlet 224 is disposed in the first air outlet duct 221, the second air outlet 234 is disposed in the second air outlet duct 231, the first air inlet 223 is disposed in the first transfer duct 222, and the second air inlet 233 is disposed in the second transfer duct 232.

[0062] Since the damper assembly 400 is used to connect or separate the first air inlet 223, the second air inlet 233 and the air supply duct 610, that is, the damper assembly 400 is located close to the first air inlet 223 and the second air inlet 233. Since the first air inlet 223 is located in the first transition duct 222 and the second air inlet 233 is located in the second transition duct 232, after the transition assembly 250 is disassembled, the first air inlet 223 and the second air inlet 233 are separated from the inspection window 240, and the damper assembly 400 is easily exposed.

[0063] The first air outlet 224 supplies air to the first chamber 141. Since the length of the first transition duct 222 is much shorter than the length of the first air outlet duct 221, the first air outlet 224 is located in the first air outlet duct 221 to ensure the air outlet range. The second air outlet duct 231 is handled similarly.

[0064] Please see Figure 6 and Figure 7In some embodiments, the adapter assembly 250 includes a first cover plate 251, a second cover plate 253, and an adapter 252. The first cover plate 251 is disposed in the first chamber 141, the second cover plate 253 is disposed in the second chamber 142, the first adapter air duct 222 and the second adapter air duct 232 are disposed in the adapter 252, the first cover plate 251 and the second cover plate 253 form a fixed cavity 251a, the adapter 252 is located in the fixed cavity 251a and installed on the first cover plate 251, and the first cover plate 251 is detachably connected to the housing 210.

[0065] Since cold air passes through the first transfer duct 222 and the second transfer duct 232, the adapter 252 needs to be made of thermal insulation material such as foam to reduce the amount of cold air lost when passing through these ducts. Because the adapter 252 is structurally fragile, it is easily damaged if exposed to the first duct module 200. The first cover plate 251 and the second cover plate 253 form a fixing cavity 251a, within which the adapter 252 is located. This protects the adapter 252. The adapter 252 is installed on the first cover plate 251, thus fixing its position and minimizing the risk of displacement that could lead to misalignment between the first transfer duct 222 and the first outlet duct 221, or between the second transfer duct 232 and the second outlet duct 231.

[0066] Since the first cover plate 251 is detachably connected to the housing 210, the adapter assembly 250 can be detachably installed in the inspection window 240. When it is necessary to remove the adapter assembly 250 from the inspection window 240, the first cover plate 251 can be separated from the housing 210. Since the adapter 252 is installed on the first cover plate 251, the first cover plate 251 can be separated from the housing 210, and the adapter 252 can be moved out together, exposing the damper assembly 400. Therefore, the second cover plate 253 can be fixedly connected to the housing 210.

[0067] Specifically, the second cover plate 253 can be integrally formed with the housing 210 to reduce the installation steps of the first air duct module 200 and improve installation efficiency.

[0068] Please see Figures 4-6 In some embodiments, both the first chamber 141 and the second chamber 142 are provided with drawers 500, the first cover plate 251 is provided with a first slide rail 254, and the second cover plate 253 is provided with a second slide rail 254. The first slide rail 254 is slidably engaged with the drawer 500 in the first chamber 141, and the second slide rail 254 is slidably engaged with the drawer 500 in the second chamber 142.

[0069] Drawer 500 is used to place items. Drawer 500 can slide into or out of the first chamber 141 and the second chamber 142 through the openings of the first chamber 141 and the second chamber 142 to retrieve items. Since the first air duct module 200 divides the refrigerator compartment 140 into the first chamber 141 and the second chamber 142, the first air duct module 200 can be regarded as the side wall of the first chamber 141 and the second chamber 142. Therefore, a slide rail 254 can be provided on the first air duct module 200 to cooperate with the drawer 500. Since the first cover plate 251 is located in the first chamber 141 and the second cover plate 253 is located in the second chamber 142, the first slide rail 254 slides with the drawer 500 in the first chamber 141, and the second slide rail 254 slides with the drawer 500 in the second chamber 142.

[0070] Of course, since the first chamber 141 and the second chamber 142 also have multiple independent compartments in the height direction, and each compartment is equipped with a drawer 500, multiple slide rails 254 can also be provided on the opposite sides of the housing 210 to cooperate with the drawer 500.

[0071] Please see Figure 3 , Figure 7 and Figure 8 In some embodiments, the refrigeration equipment 10 further includes a connecting member 300 installed on the housing 100, and a damper assembly 400 installed on the connecting member 300. The connecting member 300 has a first air outlet 321 and a second air outlet 322 that can communicate with the air supply duct 610. The first air outlet 321 is connected to the first air inlet 223, and the second air outlet 322 is connected to the second air inlet 233. The first air outlet 321 and the second air outlet 322 are located inside the maintenance window 240. The damper assembly 400 is used to open or close the first air outlet 321 and the second air outlet 322.

[0072] Since the first air outlet 321 and the second air outlet 322 can be connected to the air supply duct 610, and the first air outlet 321 is connected to the first air inlet 223, and the second air outlet 322 is connected to the second air inlet 233, that is, when the first air outlet 321 and the second air outlet 322 are connected to the air supply duct 610, the cold air in the air supply duct 610 enters the first air inlet 223 through the first air outlet 321 and enters the second air inlet 233 through the second air outlet 322. Since the damper assembly 400 is used to open or close the first air outlet 321 and the second air outlet 322, when the damper assembly 400 opens the first air outlet 321 and the second air outlet 322, the first air outlet 321 and the second air outlet 322 are connected to the air supply duct 610; when the damper assembly 400 closes the first air outlet 321 and the second air outlet 322, the first air outlet 321 and the second air outlet 322 are separated from the air supply duct 610, and the damper assembly 400 can adjust the air volume when the first air outlet 321 and the second air outlet 322 are open.

[0073] It is evident that the damper assembly 400 is located on the side of the first air outlet 321 and the second air outlet 322 away from the adapter assembly 250. Therefore, when the adapter assembly 250 is removed, the damper assembly 400 is not directly exposed, but is exposed through the first air outlet 321 and the second air outlet 322. That is, maintenance personnel can observe the condition of the damper assembly 400 and perform maintenance through the first air outlet 321 and the second air outlet 322.

[0074] Please see Figures 3-5 In some embodiments, the connecting member 300 also has a first return air inlet 323 and a second return air inlet 324 that are connected to the return air duct 160. The first return air inlet 323 is connected to the first chamber 141, and the second return air inlet 324 is connected to the second chamber 142.

[0075] The return air duct 160 is installed in the housing 100. The gas in the first chamber 141 and the second chamber 142 can enter the return air duct 160 through the first return air inlet 323 and the second return air inlet 324 respectively, and then enter the supply air duct 610 for cooling. After forming cold air, it enters the first air duct 220 and the second air duct 230 through the first air outlet 321 and the second air outlet 322 respectively, so as to supply cold air to the first chamber 141 and the second chamber 142 respectively. The heated gas then enters the first return air inlet 323 and the second return air inlet 324 respectively to realize the gas circulation.

[0076] Since the first air supply outlet 321, the second air supply outlet 322, the first return air outlet 323, and the second return air outlet 324 are all located in the connecting member 300, the connecting member 300 is an integrated air supply and return structure, which integrates air supply and return, thereby improving the integration of the refrigeration equipment 10 and simplifying the structure of the refrigeration equipment.

[0077] In some embodiments, the refrigeration device 10 further includes an odor removal module 700, and the first air duct module 200 further includes an odor removal air duct 260. At least a portion of the odor removal air duct 260 is installed inside the housing 210, and the odor removal module 700 is disposed inside the odor removal air duct 260. The first return air vent 323 and the second return air vent 324 are connected to the odor removal air duct 260.

[0078] At least a portion of the odor-removing air duct 260 is installed inside the housing 210. This means that the entire odor-removing air duct 260 can be installed inside the housing 210, or only a portion of the odor-removing air duct 260 can be installed inside the housing 210.

[0079] If strong-smelling foods, such as dried pickles or hot pot base, are stored inside the refrigeration equipment 10, the odor will transfer to other items, leading to a poor user experience. Therefore, an odor-removing module 700 is required for odor removal. Since the odor-removing duct 260 is connected to the first return air inlet 323 and the second return air inlet 324, the gas from the first chamber 141 and the second chamber 142 can also enter the odor-removing duct 260 through these inlets. After being purified by the odor-removing module 700, the clean gas is then blown out through the odor-removing duct 260. In other words, the first return air inlet 323 and the second return air inlet 324 serve both as return air for gas circulation and as odor-removing inlets, eliminating the need for a separate odor-removing inlet and simplifying the structure of the duct module 200.

[0080] Furthermore, the odor-removing air duct 260 is located within the first air duct module 200, and the refrigeration device 10 integrates the odor-removing module 700 within the odor-removing air duct 260, effectively utilizing the internal space of the first air duct module 200. This reduces the space occupied by the odor-removing module 700 and the odor-removing air duct 260 on the remaining space of the refrigeration device 10, which helps to reduce the overall size of the refrigeration device 10, allowing it to develop towards smaller size and ultra-thin designs. The structure and principle of the odor-removing module 700 are diverse and well-known to those skilled in the art, and will not be elaborated upon here.

[0081] Please see Figure 3 To improve space utilization, the first air duct 220, the second air duct 230, and the odor-removing air duct 260 can be arranged side-by-side within the partition along the depth direction of the housing 100, making full use of the space within the housing 210 and achieving integration of the first air duct 220, the second air duct 230, and the odor-removing air duct 260, thus facilitating a compact structure. Furthermore, since the first air duct 220, the second air duct 230, and the odor-removing air duct 260 are spaced apart within the housing 210, the cold air flowing in the first air duct 220, the cold air flowing in the second air duct 230, and the gas flowing in the odor-removing air duct 260 do not interfere with each other.

[0082] Of course, the housing 210 also has a odor-removing air outlet 262 that is connected to both the first chamber 141 and the second chamber 142. The clean gas purified by the odor-removing module 700 then enters the first chamber 141 and the second chamber 142 through the odor-removing air outlet 262 respectively.

[0083] Specifically, part of the odor-removing air duct 260 is disposed in the housing 210, and part is disposed in the adapter assembly 250, with the odor-removing module 700 installed in the adapter assembly 250. Since the adapter assembly 250 is detachable, when the odor-removing module 700 needs maintenance, the adapter assembly 250 can be removed from the maintenance window 240, thus facilitating the maintenance of the odor-removing module 700.

[0084] Please see Figure 4 , Figure 5 and Figure 8 In some embodiments, a first return air inlet 335 and a second return air inlet 336 may be provided on the connecting member 300. The first return air inlet 335 is connected to the first return air outlet 323, and the second return air inlet 336 is connected to the second return air outlet 324. The gas in the first chamber 141 can directly enter the odor-removing air duct 260 for odor removal through the first return air outlet 323, and can sequentially enter the return air duct 160 through the first return air outlet 323 and the first return air inlet 335. The same applies to the gas in the second chamber 142. Parts of the first return air inlet 335 and the second return air inlet 336 are covered by the air duct module, while parts are exposed outside the air duct module. Therefore, the gas in the first chamber 141 can also directly enter the return air duct 160 through the part of the first return air inlet 335 exposed outside the air duct module, without limitation.

[0085] Please see Figure 8 and Figure 9 In some embodiments, the connecting member 300 includes a support portion 310 and a mounting portion 320. The support portion 310 is mounted on the housing 100, and the mounting portion 320 is detachably mounted on the support portion 310. A first air outlet 321 and a second air outlet 322 are disposed on the mounting portion 320, and a damper assembly 400 is mounted on the mounting portion 320.

[0086] Since the first air outlet 321 and the second air outlet 322 are located in the mounting section 320, meaning that the cold air in the air supply duct 610 will enter the mounting section 320, the mounting section 320 also needs to be made of thermal insulation material such as foam to reduce the amount of cold air lost when passing through it. Of course, since the first air outlet 321 and the second air outlet 322 are located in the mounting section 320, the damper assembly 400 may also be installed in the mounting section 320 to facilitate opening and closing the first air outlet 321 and the second air outlet 322. Because the structure of the mounting section 320 is relatively fragile, it is supported by a support section 310, which can be made of plastic.

[0087] Since the mounting part 320 is detachably mounted on the support part 310, and the damper assembly 400 is mounted on the mounting part 320, when the damper assembly 400 needs to be repaired, after the adapter assembly 250 is removed from the inspection window 240, the mounting part 320 can be removed as well, so that the mounting part 320 and the damper assembly 400 can be taken out of the housing 100 together for repair. In other words, if only the damper assembly 400 needs to be inspected, it can be observed through the first air outlet 321 and the second air outlet 322; if the damper assembly 400 needs to be repaired, it must be taken out for repair.

[0088] In some embodiments, the bottom wall of the refrigerator compartment 140 is provided with an installation opening 143, the connecting member 300 has an air supply surface 333, the first air supply outlet 321 and the second air supply outlet 322 are disposed on the air supply surface 333, the air supply surface 333 is disposed on the installation opening 143, the adapter component 250 contacts the air supply surface 333, the first air inlet 223 is correspondingly disposed with the first air supply outlet 321, and the second air inlet 233 is correspondingly disposed with the second air supply outlet 322.

[0089] The adapter component 250 contacts the air supply surface 333, and the first air inlet 223 is correspondingly set with the first air supply outlet 321, and the second air inlet 233 is correspondingly set with the second air supply outlet 322, thereby achieving communication between the first air inlet 223 and the first air supply outlet 321, and between the second air inlet 233 and the second air supply outlet 322. Of course, the air supply surface 333 is located at the bottom of the maintenance window 240, so that after removing the adapter component 250, the damper component 400 can be exposed in the maintenance window 240.

[0090] Please see Figure 3 In some embodiments, the refrigeration equipment 10 further includes a freezer compartment 150 and a second air duct module 600, a connecting member 300 disposed between the refrigerator compartment 140 and the freezer compartment 150, the second air duct module 600 installed in the freezer compartment 150, an air supply duct 610 disposed in the second air duct module 600, and the second air duct module 600 further includes an evaporator 120 and a guide member 130 installed in the air supply duct 610.

[0091] The air intake component 130 drives cold air to circulate within each chamber of the refrigeration unit 10, improving refrigeration efficiency. The evaporator 120 absorbs heat to achieve the refrigeration effect. Since the freezer compartment 150 requires a larger cooling capacity, the evaporator 120 and the air intake component 130 are installed in the air supply duct 610. The air supply duct 610 supplies air to the freezer compartment 150, achieving refrigeration. Simultaneously, the cold air in the air supply duct 610 flows to the first air duct 220 and the second air duct 230 to refrigerate the refrigerator compartment 140. The connecting component 300 connects the air supply duct 610 with the first air duct 220 and the second air duct 230; therefore, the connecting component 300 is positioned between the refrigerator compartment 140 and the freezer compartment 150.

[0092] In some embodiments, the refrigeration device 10 further includes a door 800, which is disposed at the opening of the chamber 140. The thickness of the door 800 is 25mm to 40mm, and the total thickness of the housing 100 and the door 800 is 450mm to 600mm.

[0093] Because the thickness of the door 800 is limited to 25mm to 40mm, the door 800 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 800 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.

[0094] Specifically, the thickness of the door 800 can be 26mm, 30mm, 32mm, 36mm, or 38mm, and the total thickness of the box 100 and the door 800 can be 480mm, 520mm, 540mm, 560mm, or 580mm.
