[0044] The refrigeration equipment has a plurality of air duct modules to supply air to different chambers, wherein the plurality of air duct modules can be connected or separated by opening and closing of the air door assembly, when the plurality of air duct modules are connected, the cold air can be transferred, so that a set of refrigeration assembly supplies air to multiple chambers.

[0045] Since the air door assembly is arranged in the box body of the refrigeration equipment, in the related art, when the air door assembly is damaged, the maintenance personnel needs to disassemble the air duct module and the related parts around it, which makes the technical difficulty of the maintenance process higher, and needs to invest more manpower, material resources and time cost. In addition, the long maintenance period may cause the refrigerator to be unable to use for a long time, affecting the daily life of the user.

[0046] In order to solve the problems in the related art to some extent, the present application provides a refrigeration equipment, which does not need to disassemble the air duct module and the related parts around it when repairing the air door assembly, greatly saving the manpower, material resources and time cost, and shortening the maintenance period.

[0047] The present application will be described below in conjunction with the drawings and specific embodiments:

[0048] Please refer to Figure 1The embodiment of the present application provides a refrigeration equipment 10, when the air door assembly 400 is repaired, the air duct module 200 and related parts around the air duct module 200 do not need to be disassembled, so that manpower, material resources and time cost are greatly saved, and the repair period is shortened.

[0049] The refrigeration equipment 10 can be a refrigerator or a freezer. In the embodiment of the present application, the refrigeration equipment 10 is taken as a refrigerator for convenience of description, and the same can be applied by analogy when the refrigeration equipment 10 is another equipment.

[0050] Please refer to Figures 2-4 In the embodiment of the present application, the refrigeration equipment 10 comprises a cabinet 100, an air duct module 200, an adapter assembly 300 and an air door assembly 400. The cabinet 100 has a chamber 140 for containing articles; the air duct module 200 is installed on the cabinet 100, the air duct module 200 has an air outlet duct 220 for sending air into the chamber 140, and the air duct module 200 is provided with an inspection window 230; the adapter assembly 300 is detachably installed on the inspection window 230; and the air door assembly 400 is installed on the cabinet 100 and used for connecting or separating the air outlet duct 220 and the air supply duct 110.

[0051] In the case that the adapter assembly 300 is disassembled, the air door assembly 400 can be exposed to the inspection window 230.

[0052] The cabinet 100 is the main structure of the whole refrigeration equipment 10, can provide a mounting base for the air duct module 200, a compressor, an evaporator 120 and the like, and can also protect the electronic components and the like. The chamber 140 is used for containing articles to be refrigerated or frozen, and has an opening through which the user can take or put articles. The air duct module 200 is installed on the cabinet 100, and the air outlet duct 220 is arranged in a housing 210 of the air duct module 200. The cold air blown out by the air outlet duct 220 is used for refrigerating or freezing the articles.

[0053] The cabinet 100 is generally a cuboid, and for convenience of description, a height direction Z, a width direction X and a thickness direction Y are defined, wherein in the use state of the refrigeration equipment 10, the vertical direction is the height direction Z, and the projection of the cabinet 100 in the vertical direction is a rectangle. The direction of the long side is the width direction X, and the direction of the wide side is the thickness direction Y.

[0054] Similarly, for convenience of description, six directions, i.e., up, down, left, right, front and back, are defined. In the height direction Z, the direction close to the top surface is up, and the direction away from the top surface is down. In the width direction X, the two directions are left and right respectively. In the thickness direction Y, the direction close to the opening of the chamber 140 is front, and the direction away from the opening of the chamber 140 is back.

[0055] Please refer toFigures 3-5 In the embodiments of the present application, the cabinet 100 further has a supply air duct 110, and the chamber 140 of the refrigeration device 10 includes a freezing chamber 142 and a refrigerating chamber 141, the supply air duct 110 can be used to supply air to the freezing chamber 142, and the exhaust air duct 220 can be used to supply air to the refrigerating chamber 141. The refrigeration device 10 further includes an evaporator 120 and a flow guide 130, the evaporator 120 is used to cool air, and the flow guide 130 is used to circulate cold air in the chamber 140 to cool the items. Since the freezing chamber 142 requires more cooling capacity, the evaporator 120 and the flow guide 130 can be arranged in the supply air duct 110, that is, the air cooled by the evaporator 120 can directly enter the freezing chamber 142 through the supply air duct 110.

[0056] Specifically, the air duct module 200 has an air outlet 221 and an air return 222 that are in communication with the exhaust air duct 220, and the flow guide 130 can make the gas in the chamber 140 enter the exhaust air duct 220 through the air return 222, and the gas in the exhaust air duct 220 flow into the chamber 140 through the air outlet 221. The cabinet 100 can have a partition plate, which is used to divide the refrigerating chamber 141 and the freezing chamber 142 into two or more independent compartments, so as to better classify and store different types of food, such as vegetables, fruits, dairy products, etc., thereby facilitating management and maintaining the best preservation state of the food. The refrigerating chamber 141 and the freezing chamber 142 each have a partition plate, and the supply air duct 110 and the exhaust air duct 220 can be arranged in the partition plate, that is, the partition plate in the refrigerating chamber 141 is configured as the housing 210 of the air duct module 200. By carrying and accommodating the supply air duct 110 and the exhaust air duct 220 through the partition plate, the space inside the partition plate can be effectively utilized, and the occupation of external space by the air duct is reduced, so that the overall structure is more compact.

[0057] The damper assembly 400 is used to communicate or separate the exhaust air duct 220 and the supply air duct 110, that is, when the damper assembly 400 is opened, the exhaust air duct 220 and the supply air duct 110 are in communication, and the cold air in the supply air duct 110 enters the exhaust air duct 220; when the damper assembly 400 is closed, the exhaust air duct 220 and the supply air duct 110 are disconnected, and the opening degree of the damper assembly 400 can be adjusted to adjust the amount of cold air entering the exhaust air duct 220 from the supply air duct 110, so as to realize temperature regulation of the refrigerating chamber 141.

[0058] In the air duct module 200, a maintenance window 230 is formed, and the adapter assembly 300 is detachably installed in the maintenance window 230. When the adapter assembly 300 is detached, the air door assembly 400 is exposed to the maintenance window 230. Therefore, when the air door assembly 400 is damaged, the adapter assembly 300 is detached from the maintenance window 230, and the air door assembly 400 can be repaired through the maintenance window 230. After the air door assembly 400 is repaired, the adapter assembly 300 is reinstalled in the maintenance window 230, so that the appearance of the air duct module 200 is complete. During the repair of the air door assembly 400, the air duct module 200 and its surrounding related parts do not need to be disassembled, which greatly saves manpower, material resources and time cost, and shortens the repair period.

[0059] It should be noted that the air duct module 200 can have more than one air outlet air duct 220. Of course, the air outlet air duct 220 and the transition air duct 325 and the air outlet 161 are one-to-one corresponding. When the air outlet 161 is more than one, the air door assembly 400 also includes more than one air door.

[0060] Please refer to Figure 4 In some embodiments, the air door assembly 400 is located below the maintenance window 230.

[0061] Since the air door assembly 400 is located below the maintenance window 230, when the adapter assembly 300 is removed from the maintenance window 230, the maintenance personnel can look down at the air door assembly 400 to facilitate maintenance.

[0062] Specifically, the air door assembly 400 can be arranged in the air outlet air duct 220, and the maintenance window 230 is arranged above the air door assembly 400, or the air door assembly 400 can also be arranged in the air supply duct 110, and the maintenance window 230 is arranged above the air supply duct 110. This is not limited.

[0063] In some embodiments, the air supply duct 110 is arranged below the air duct module 200, the maintenance window 230 is arranged at one end of the air duct module 200 close to the air supply duct 110, and the air door assembly 400 is installed in the air supply duct 110.

[0064] The freezing chamber is arranged below the refrigerating chamber. Since the air supply air duct 110 is used for supplying air to the freezing cavity 142 and the air outlet air duct 220 is used for supplying air to the refrigerating cavity 141, the air supply air duct 110 is arranged below the air outlet air duct 220, i.e. the air supply air duct 110 is arranged below the air duct module 200. Since the evaporator 120 and the flow guide 130 are both arranged in the air supply air duct 110, and the air outlet air duct 220 is only used for air supply, the size of the air supply air duct 110 is greater than the size of the air outlet air duct 220, so as to facilitate the installation of the air door assembly 400, the air door assembly 400 can be arranged in the air supply air duct 110, and the access window 230 is arranged at the end of the air duct module 200 close to the air supply air duct 110, so that after the adapter assembly 300 is removed from the access window 230, the air door assembly 400 can be exposed to the access window 230.

[0065] Of course, in other embodiments, the evaporator 120 and the flow guide 130 can also be arranged in the air outlet air duct 220 alone, which is not limited.

[0066] In some embodiments, the cabinet 100 is provided with an air opening 161, the air opening 161 is arranged at the bottom of the access window 230, the air door assembly 400 is arranged at the side of the air opening 161 away from the access window 230, and the air door assembly 400 can open or close the air opening 161.

[0067] That is, the air door assembly 400 opens or closes the air opening 161 to realize the communication or separation of the air supply air duct 110 and the air outlet air duct 220. The air door assembly 400 can open or close the air opening 161 by rotating. When the air door assembly 400 opens the air opening 161, the air opening 161 communicates the air supply air duct 110 and the air outlet air duct 220, and the cold air in the air supply air duct 110 enters the air outlet air duct 220 through the air opening 161. When the air door assembly 400 closes the air opening 161, i.e. the air door assembly 400 covers the air opening 161, the air supply air duct 110 and the air outlet air duct 220 are separated.

[0068] Since the air opening 161 is arranged at the bottom of the access window 230, the air door assembly 400 is arranged at the side of the air opening 161 away from the access window 230, i.e. when the adapter assembly 300 is removed from the access window 230, the air opening 161 will be exposed to the access window 230, and the air door assembly 400 will be exposed to the air opening 161, i.e. the maintenance personnel can maintain the air door assembly 400 through the air opening 161.

[0069] In some embodiments, the cabinet 100 includes a main body 150 and a mounting portion 160, the air duct module 200 is arranged on the main body 150, the mounting portion 160 is detachably arranged on the main body 150 and below the access window 230, the air opening 161 is arranged on the mounting portion 160, and the air door assembly 400 is arranged on the side of the mounting portion 160 away from the access window 230.

[0070] The mounting portion 160 can be arranged at the end of the air supply air duct 110 close to the air outlet air duct 220, the bottom of the adapter assembly 300 can be in contact with the mounting portion 160, and the mounting portion 160 separates the air outlet air duct 220 and the air supply air duct 110. According to the damage condition of the air door assembly 400, in order to facilitate the maintenance of the air door assembly 400, sometimes the air door assembly 400 needs to be disassembled from the cabinet 100 for maintenance. Since the mounting portion 160 is detachably mounted on the main body 150, and the air door assembly 400 is mounted on the mounting portion 160, when the air door assembly 400 needs to be repaired, the mounting portion 160 can be directly disassembled from the main body 150, so that the air door assembly 400 is taken out of the cabinet 100, so as to maintain the air door assembly 400.

[0071] Specifically, the side of the mounting portion 160 away from the maintenance window 230 has a fixing groove 162, and the air door assembly 400 is mounted in the fixing groove 162 to facilitate the installation or disassembly of the air door assembly 400. The mounting portion 160 can be connected with the main body 150 by bolts to ensure the fixing effect.

[0072] In some embodiments, the adapter assembly 300 has a transition air duct 325, and the transition air duct 325 communicates the air outlet air duct 220 and the air port 161.

[0073] Since the transition air duct 325 communicates the air outlet air duct 220 and the air port 161, that is, in the case that the air port 161 is opened, the cold air in the air supply air duct 110 can enter the air supply air duct 110 through the air port 161 and the transition air duct 325 in turn. That is, the adapter assembly 300 not only covers the maintenance window 230 to make the appearance of the air duct module 200 complete, but also has the function of communicating the air outlet air duct 220 and the air port 161, so that the cold air in the air supply air duct 110 can directly enter the air outlet air duct 220 through the adapter assembly 300, without the need to additionally arrange an air duct to communicate the air outlet air duct 220 and the air port 161, so that the structure of the air duct module 200 is more simple and occupies less space.

[0074] Please refer to Figure 6 and Figure 7It can be understood that, since the air duct module 200 is configured to blow air from the top and suck air from the bottom to realize the circulation of air in the chamber 140, the maintenance window 230 is arranged at the end of the air duct module 200 close to the air supply air duct 110, that is, the adapter assembly 300 is arranged at the lower end of the air duct module 200, and the transition air duct 325 is connected to the air outlet air duct 220 and the air outlet 161, so the air inlet 222 can be arranged on the adapter assembly 300. Since the air sucked needs to be cooled by the evaporator 120, and the evaporator 120 and the flow guide 130 are arranged in the air supply air duct 110, the air supply air duct 110 is provided with an air return channel, and the air inlet 222 is connected to the air return channel, so that air can enter the air supply air duct 110 through the air inlet 222 and the air return channel, and then enter the air supply air duct 110 after being cooled by the evaporator 120, thereby realizing the circulation of air. Specifically, the air return channel is arranged in the mounting portion 160, that is, the mounting portion 160 is an integrated structure of air supply and return, and the cold air in the air supply air duct 110 enters the air outlet air duct 220 through the air outlet 161, and the hot air enters the air supply air duct 110 through the air return channel.

[0075] Please refer to 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, and the transition air duct 325 is arranged in the mounting member 320. The cover plate 310 is detachably connected to the air duct module 200.

[0076] Since the mounting member 320 is mounted on the cover plate 310, and the cover plate 310 is detachably connected to the air duct module 200, when the adapter assembly 300 needs to be removed, the cover plate 310 is separated from the air duct module 200, and then the adapter assembly 300 and the maintenance window 230 can be removed. Similarly, when the adapter assembly 300 needs to be installed, the adapter assembly 300 is first installed in the maintenance window 230, and then the cover plate 310 is connected to the air duct module 200. Specifically, since the partition plate can serve as the housing 210 of the air duct module 200, the cover plate 310 can be connected to the partition plate.

[0077] The transition air duct 325 is arranged in the mounting member 320. Since the cold air passes through the transition air duct 325, in order to reduce the loss of cold energy when the cold air passes through the transition air duct 325, at least part of the mounting member 320 needs to be made of heat insulation material, that is, at least the two sides of the transition air duct 325 need to be made of heat insulation material. Specifically, at least part of the mounting member 320 can be made of foam.

[0078] Please refer to Figure 9 and Figure 10 In some embodiments, the air outlet 161 is provided with a docking member 163, the mounting member 320 is provided with a docking groove 321, and the docking member 163 is docked in the docking groove 321, so that the transition air duct 325 is aligned with the air outlet 161.

[0079] Since the adapter assembly 300 is detachably installed on the maintenance window 230, the adapter assembly 300 needs to be repeatedly disassembled and installed every time the damper assembly 400 needs to be maintained. If the transition air duct 325 is not completely aligned with the air outlet 161 during the installation process, a misalignment will occur, which will affect the air supply efficiency. Therefore, the air outlet 161 is provided with a docking piece 163, and the mounting piece 320 is provided with a docking groove 321. The docking piece 163 is docked in the docking groove 321, so that the transition air duct 325 is aligned with the air outlet 161, so that the cold air in the air supply duct 110 can fully pass through the air outlet 161 into the transition air duct 325, to ensure the air supply efficiency. Moreover, since the position of the air duct module 200 is fixed and unchanged, the transition air duct 325 is aligned with the air outlet 161, i.e., aligned with the air outlet 161. Specifically, since the air outlet 161 is provided on the mounting portion 160, the docking piece 163 is also provided on the mounting portion 160.

[0080] Since the adapter assembly 300 is provided above the air outlet 161, the docking piece 163 is provided on the upper portion of the air outlet 161, and the docking groove 321 is provided on the bottom of the mounting piece 320. When the adapter assembly 300 is installed, the docking piece 163 is docked in the docking groove 321, so that the transition air duct 325 is aligned with the air outlet 161.

[0081] Of course, in other embodiments, the docking piece 163 can be provided on the air duct module 200, and the mounting piece 320 is provided with a docking groove 321. The docking piece 163 is docked in the docking groove 321 to align the transition air duct 325 with the air outlet 161, which is not limited.

[0082] In some embodiments, the air duct module 200 further comprises a sealing piece 330, which is provided on the outer surface of the mounting piece 320, and at least part of the sealing piece 330 is located between the mounting piece 320 and the air outlet 161.

[0083] Since the transition air duct 325 is in communication with the air outlet 161, i.e., the cold air enters the air outlet 161 from the transition air duct 325, and since the adapter assembly 300 is detachable, there is a gap between the adapter assembly 300 and the transition air duct 325. Therefore, in order to reduce the leakage of cold air, the sealing piece 330 needs to be provided on the mounting piece 320 to seal the gap between the adapter assembly 300 and the air outlet 161.

[0084] The at least partial sealing member 330 is located between the mounting member 320 and the air outlet duct 220, that is, the sealing member 330 can be entirely attached to the surface of the mounting member 320 in contact with the air outlet duct 220, or the sealing member 330 can be partially attached to the surface of the mounting member 320 in contact with the air outlet duct 220, and the sealing member 330 can be attached to other surfaces of the mounting member 320. When the adapter assembly 300 is installed in place, the sealing member 330 is arranged between the mounting member 320 and the air outlet duct 220 to seal.

[0085] Specifically, the sealing member 330 can be made of PU sponge, and the thickness of the sealing member 330 can be 2mm-4mm.

[0086] Please refer to Figure 4 In some embodiments, the air duct module 200 has a fixing surface 211, the cover plate member 310 forms a fixing cavity 311 with the fixing surface 211, and the mounting member 320 is located in the fixing cavity 311 and is mounted on the cover plate member 310.

[0087] Since at least part of the mounting member 320 is made of foam material, the structure is relatively fragile, so the mounting member 320 needs to be protected to avoid damage to the mounting member 320 as much as possible and affect the heat preservation and insulation effect. Since the air duct module 200 has a fixing surface 211, the cover plate member 310 forms a fixing cavity 311 with the fixing surface 211, and the mounting member 320 is located in the fixing cavity 311, so the fixing cavity 311 can protect the mounting member 320.

[0088] It should be noted that specifically, the cover plate member 310 and the fixing surface 211 can be arranged on the left and right sides of the mounting member 320, and the cover plate member 310 and the fixing surface 211 together with the inner walls of the front and rear of the maintenance window 230 protect the circumferential side of the mounting member 320. Since the upper part of the transition air duct 325 needs to be communicated with the air outlet duct 220, and the lower part needs to be communicated with the air inlet 161, the upper surface and the lower surface of the mounting member 320 are exposed to the fixing cavity 311.

[0089] Please refer to Figure 7 and Figure 8 In some embodiments, the refrigeration equipment 10 further comprises a fixing member 313, the air duct module 200 is provided with a first fixing hole 212, the cover plate member 310 is provided with a second fixing hole 312, and the fixing member 313 is arranged in the first fixing hole 212 and the second fixing hole 312.

[0090] The fixing member 313 is arranged in the first fixing hole 212 and the second fixing hole 312, that is, the cover plate member 310 is connected to the air duct module 200. Of course, the fixing member 313 can be detachably mounted in the first fixing hole 212 and the second fixing hole 312. When the cover plate member 310 and the air duct module 200 need to be separated, the fixing member 313 can be removed from the first fixing hole 212 and the second fixing hole 312.

[0091] Specifically, the fixing member 313 can be a bolt, the first fixing hole 212 and the second fixing hole 312 can be screw holes, and the fixing member 313 is screwed into the first fixing hole 212 and the second fixing hole 312, that is, the cover plate member 310 is connected to the air duct module 200.

[0092] Please refer to Figure 11 and Figure 12 In some embodiments, the mounting member 320 includes a mounting body 322 and a fixing plate 323 arranged on the outer surface of the mounting body 322, and the transition air duct 325 is arranged in the mounting body 322. The cover plate member 310 is detachably connected to the fixing plate 323.

[0093] Since the transition air duct 325 is arranged in the mounting body 322, the mounting body 322 is made of foam to achieve the heat insulation function of the transition air duct 325. However, since the foam material is difficult to be rigidly connected, the fixing plate 323 is arranged on the outer surface of the mounting body 322. At least part of the fixing plate 323 is arranged opposite to the cover plate member 310, and the cover plate member 310 is connected between the fixing plate 323, that is, the cover plate member 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 member 310.

[0094] The heat insulation performance of the mounting body 322 will decrease after long-term use. Since the cover plate member 310 is detachably connected to the fixing plate 323, the cover plate member 310 and the fixing plate 323 can be disassembled when the mounting body 322 needs to be replaced.

[0095] Please refer to Figure 13 In some embodiments, one end of the cover plate member 310 has a connecting plate 314, the connecting member includes a fixing portion 314a and an overlapping portion 314b arranged at an angle, the second fixing hole 312 is arranged in the fixing portion 314a, the side portion of the shell 210 is provided with an overlapping member 213, and the overlapping portion 314b overlaps the overlapping member 213.

[0096] Since the adapter assembly 300 is detachably installed on the inspection window 230, the adapter assembly 300 needs to be repeatedly disassembled and installed every time the air outlet duct 220 needs to be inspected. If the transition air duct 325 and the air outlet duct 220 are not completely aligned during the installation process of the adapter assembly 300, the positioning will affect the air supply efficiency. Therefore, when the adapter assembly 300 is installed, the adapter assembly 300 needs to be positioned.

[0097] The connecting plate 314 is arranged at one end of the cover plate 310 in the height direction. Since the cover plate 310 has the overlapping portion 314b, the side portion of the shell 210 is provided with the overlapping member 213, and the overlapping portion 314b overlaps the overlapping member 213. Therefore, when the adapter assembly 300 is installed, the overlapping portion 314b is first overlapped on the overlapping member 213, and then the shell 210 and the cover plate 310 are connected through the fixing member 313, so that the transition air duct 325 and the air outlet air duct 220 can be aligned 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 connecting member do not interfere with each other.

[0098] Specifically, the fixing portion 314a and the overlapping portion 314b can be arranged vertically. The fixing portion 314a is arranged in the height direction, and the overlapping portion 314b is arranged in the width direction. The overlapping portion 314b is arranged above the overlapping member 213, and the fixing portion 314a is arranged on the side away from the overlapping member 213 to avoid the overlapping member 213.

[0099] In some embodiments, the first fixing hole 212 is arranged in a staggered manner with the overlapping member 213.

[0100] Since the connecting member includes the fixing portion 314a and the overlapping portion 314b, the fixing portion 314a is connected with the shell 210, and the overlapping portion 314b overlaps the overlapping member 213. The fixing portion 314a and the overlapping portion 314b are arranged at an angle, so that the fixing portion 314a and the overlapping portion 314b do not interfere with each other. In order to make the first fixing hole 212 and the overlapping member 213 also not interfere with each other, the first fixing hole 212 is arranged in a staggered manner with the overlapping member 213.

[0101] Specifically, the overlapping member 213 is arranged in the thickness direction, and the fixing member 313 is provided with two, so that the first fixing hole 212 is also provided with two, and the overlapping member 213 is arranged between the two fixing holes.

[0102] In some embodiments, the other end of the cover plate 310 has a support plate 315 which is supported on the mounting member 320.

[0103] The other end of the cover plate member 310 is the other end of the cover plate member 310 in the height direction. Since the cover plate member 310 and the mounting member 320 are two separate structures, the relative position of the mounting member 320 and the cover plate member 310 remains fixed after the cover plate member 310 is accurately positioned by the lapping effect of the lapping part 314b and the lapping part 213, so as to ensure that the transition air duct 325 is aligned with the air outlet air duct 220 after the adapter assembly 300 is installed. The support plate 315 is arranged at the other end of the cover plate member 310, and the support plate 315 is supported on the mounting member 320, so that the mounting member 320 is more stable when installed on the cover plate member 310, and the position of the mounting member 320 relative to the cover plate member 310 is reduced. After the cover plate member 310 is positioned, the transition air duct 325 of the mounting member 320 can be aligned with the air outlet air duct 220.

[0104] Referring to Figure 3 and Figure 7 In some embodiments, the refrigeration equipment 10 further comprises a drawer 500, the drawer 500 is installed in the cavity 140, and the side of the cover plate member 310 facing the cavity 140 is provided with a sliding rail 316, and the drawer 500 is in sliding cooperation with the sliding rail 316.

[0105] The drawer 500 is used to place articles, and the cavity 140 has an opening through which the drawer 500 can slide into or out of the cavity 140 to take or place articles. Since the partition plate is configured as the housing 210 of the air duct module 200, the adapter assembly 300 is also arranged in the partition plate, that is, the adapter assembly 300 also becomes a part of the cavity 140. In the embodiment of the present application, the sliding function of the drawer 500 is realized by arranging the sliding rail 316 on the side of the cover plate member 310 facing the cavity 140 and the drawer 500 in sliding cooperation with the sliding rail 316, by taking advantage of the arrangement position of the adapter assembly 300. That is, the adapter assembly 300 can not only be used for maintenance of the air outlet air duct 220, but also can be integrated with the sliding rail 316 function cooperating with the drawer 500, so as to integrate multiple functions in one, thereby simplifying the structure of the refrigeration equipment 10 and making the overall structure more compact.

[0106] In addition, since the adapter assembly 300 is detachable, when the sliding rail 316 fails, the sliding rail 316 can be easily repaired.

[0107] In some embodiments, the refrigeration equipment 10 further comprises a door body 700, the door body 700 is arranged at the opening of the cavity 140, the thickness of the door body 700 is 25mm-40mm, and the total thickness of the cabinet 100 and the door body 700 is 450mm-600mm.

[0108] Since the thickness of the door body 700 is limited to 25mm-40mm, i.e. the thickness of the door body 700 is thin, it is convenient for a user to open and close the door. Since the total thickness of the cabinet 100 and the door body 700 is limited to 450mm-600mm, i.e. the thickness of the whole refrigeration equipment is thin, the occupied area of the refrigeration equipment can be reduced, and it is convenient for carrying.

[0109] Specifically, the thickness of the door body 700 can be 26mm, 30mm, 32mm, 36mm, 38mm, and the total thickness of the cabinet 100 and the door body 700 can be 480mm, 520mm, 540mm, 560mm, 580mm.
