Description

Technical Field

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

[0002] 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.

[0003] 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. Summary of the Invention

[0004] This application aims to at least partially address the technical challenges of maintaining air outlet ducts, which involves significant technical difficulties and requires substantial investment of manpower, resources, and time. To this end, this application provides a refrigeration device.

[0005] In a first aspect, embodiments of this application provide a refrigeration device, including:

[0006] The box has chambers for holding items;

[0007] A duct module is installed in the enclosure. The duct module includes a housing and an air outlet duct disposed in the housing. The air outlet duct is used to supply air to the cavity. The duct module is provided with an inspection window.

[0008] The adapter assembly is detachably installed in the inspection window;

[0009] A support platform is disposed within the cavity and spaced apart from the inspection window;

[0010] The adapter assembly has a first connecting surface, the maintenance window has a second connecting surface, and the adapter assembly can rotate relative to the air duct module around the support platform, so that the first connecting surface contacts the second connecting surface.

[0011] In the duct module proposed in this application embodiment, since the duct module has an inspection window and the adapter component is detachably installed in the inspection window, when the outlet duct needs to be inspected, the adapter component can be removed from the inspection window, and the outlet duct can be repaired through the inspection window. After the outlet duct is repaired, the adapter component can be reinstalled in the inspection window. The whole process only requires the adapter component to be removed, without disassembling the duct module and other surrounding components, thereby greatly saving manpower, material resources and time costs, and shortening the maintenance cycle.

[0012] In some embodiments, the chamber has a bottom wall that is angled to the air duct module, a portion of the adapter assembly is disposed on the bottom wall, and the support platform is mounted on the bottom wall. The adapter assembly is rotatable relative to the air duct module about the support platform along the direction from the bottom wall to the air duct module, such that the first connecting surface contacts the second connecting surface.

[0013] In some embodiments, a support corner is formed between the side of the support platform near the inspection window and the bottom wall, and the adapter assembly has a support plate on the side near the support platform. The support plate is set at an angle to the side, and the adapter assembly can rotate relative to the air duct module by cooperating with the support corner through the support plate.

[0014] In some implementations, the support corner is arc-shaped.

[0015] In some embodiments, the width of the support plate is greater than the height of the support platform.

[0016] In some embodiments, the width of the support plate is 10mm to 15mm.

[0017] In some embodiments, when the first connecting surface is in contact with the second connecting surface, the support plate abuts against the side surface.

[0018] In some embodiments, both the first connecting surface and the second connecting surface are inclined.

[0019] In some embodiments, the adapter assembly further includes a seal, at least a portion of which is fitted against the first connection surface.

[0020] In some embodiments, the adapter assembly has a transition duct that communicates with the outlet air duct.

[0021] In some embodiments, the air duct module is installed inside the refrigeration chamber of the refrigeration equipment, and the housing divides the refrigeration chamber into a first chamber and a second chamber. Attached Figure Description

Detailed Implementation

[0037] 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.

[0038] 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.

[0039] 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.

[0040] 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.

[0041] 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.

[0042] 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.

[0043] 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 air outlet duct, greatly saving manpower, material resources, and time costs, and shortening the maintenance cycle.

[0044] This application is described below with reference to the accompanying drawings and specific embodiments:

[0045] Please see Figure 1 and Figure 2 This application provides a refrigeration device 10 that eliminates the need to disassemble the air duct module 200 and its surrounding components when repairing the air outlet duct 220, greatly saving manpower, material resources and time costs, and shortening the maintenance cycle.

[0046] 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.

[0047] Please see Figures 3-5In this embodiment, the refrigeration device 10 includes a housing 100, an air duct module 200, a connecting assembly 300, and a support platform 600. The housing 100 has a chamber 140 for containing items; the air duct module 200 is installed in the housing 100, and the air duct module 200 includes a housing 210 and an air outlet duct 220 disposed in the housing 210. The air outlet duct 220 is used to supply air into the chamber 140, and the air duct module 200 has an inspection window 230; the connecting assembly 300 is detachably installed in the inspection window 230; the support platform 600 is disposed in the chamber 140 and spaced apart from the inspection window 230.

[0048] The adapter component 300 has a first connecting surface 324, and the inspection window 230 has a second connecting surface 231. The adapter component 300 can rotate around the support platform 600 relative to the air duct module 200, so that the first connecting surface 324 and the second connecting surface 231 come into contact.

[0049] 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, the air intake component 130, and the evaporator 120, and also protects the aforementioned electronic components. The chamber 140 is used to hold items to be refrigerated or frozen. The chamber 140 has an opening, through which users can access and place items. The air duct module 200 is installed in the housing 100. The air duct module 200 includes a housing 210, and an air outlet duct 220 is disposed within the housing 210. The cold air blown out by the air outlet duct 220 is used to refrigerate or freeze the items.

[0050] The enclosure 100 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 enclosure 100220 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.

[0051] Similarly, for ease of description, six directions are defined: up, down, left, right, front, and back. In the height direction Z, up is closer to the top surface and down is further away from the top surface. In the width direction X, the two directions are left and right, respectively. In the thickness direction Y, the opening closer to chamber 140 is front, and the opening further away from chamber 140 is back.

[0052] Please see Figures 3-6In this embodiment, the housing 100 also includes an air supply duct 110. The chamber 140 of the refrigeration device 10 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 refrigeration device 10 also includes an evaporator 120 and a guide element 130. The evaporator 120 cools the air, and the guide element 130 circulates the cold air within the chamber 140 to cool the items. Since the freezing chamber 142 requires a larger cooling capacity, the evaporator 120 and the guide element 130 can be located within the air supply duct 110, meaning that the air cooled by the evaporator 120 can directly enter the freezing chamber 142 through the air supply duct 110. Specifically, the air duct module 200 has an air outlet 221 and a return air outlet 222 that are connected to the air outlet duct 220. The guide member 130 enables the gas in the chamber 140 to enter the air outlet duct 220 through the return air outlet 222, and the gas in the air outlet duct 220 to flow from the air outlet 221 to the chamber 140.

[0053] Since the duct module 200 has a maintenance window 230, and the adapter component 300 is detachably installed in the maintenance window 230, the adapter component 300 can be regarded as a detachable part of the duct module 200. Therefore, when the outlet duct 220 needs maintenance, the adapter component 300 can be removed from the maintenance window 230, and the outlet duct 220 can be repaired through the maintenance window 230. After the outlet duct 220 is repaired, the adapter component 300 can be reinstalled into the maintenance window 230. The whole process only requires the adapter component 300 to be removed, without disassembling the duct module 200 and other surrounding components, which greatly saves manpower, material resources and time costs, and shortens the maintenance cycle.

[0054] The adapter component 300 has a first connecting surface 324, and the inspection window 230 has a second connecting surface 231. The second connecting surface 231 is disposed on the inner wall of the inspection window 230. The adapter component 300 can rotate relative to the air duct module 200 around the support platform 600, so that the first connecting surface 324 and the second connecting surface 231 come into contact, thereby ensuring a tight fit between the adapter component 300 and the air duct module 200, so as to maintain the integrity of the appearance of the air duct module 200 as much as possible and reduce the exposure of the inspection window 230. However, when installing the adapter component 300, if the adapter component 300 is directly pushed into the inspection window 230, the first connecting surface 324 and the second connecting surface 231 will rub and squeeze throughout the process, which will cause damage to the adapter component 300 and the air duct module 200 over time. In this embodiment, the support platform 600 can be regarded as a pivot, and the adapter component 300 can rotate into the maintenance window 230 with the support component as the fulcrum. During this process, since the adapter component 300 is in a rotating state, that is, the first connecting surface 324 rotates relative to the second connecting surface 231, the first connecting surface 324 and the second connecting surface 231 will not be squeezed throughout the entire process. Instead, there will be slight squeezing between the first connecting surface 324 and the second connecting surface 231 only after the adapter component 300 is fully installed in place. This can reduce the damage to the adapter component 300 and the air duct module 200 during the installation of the adapter component 300.

[0055] It should be noted that the interval between the support platform 600 and the inspection window 230 can be designed according to the size of the adapter component 300, and the position of the support platform 600 remains fixed, so that the adapter component 300 can be rotated around the support platform 600 as a fulcrum and can be inserted into the inspection window 230, and the first connecting surface 324 and the second connecting surface 231 can be in contact. In this way, the installation accuracy of the adapter component 300 can also be improved.

[0056] Please see Figure 3 In some embodiments, the air duct module 200 is installed in the refrigeration chamber 141 of the refrigeration equipment 10, and the housing 210 divides the refrigeration chamber 141 into a first chamber 141a and a second chamber 141b.

[0057] The housing 210 divides the refrigeration chamber 141 into a first chamber 141a and a second chamber 141b, allowing for better classification and storage of different types of food, such as vegetables, fruits, and dairy products, thus facilitating management and maintaining optimal freshness. In other words, the housing 210 serves both to divide the refrigeration chamber 141 into zones and to simultaneously support and accommodate the air duct 220 and the transfer assembly 300. In practical applications, the partition plate within the refrigeration chamber 141 can be directly configured as the housing 210, supporting and accommodating the air duct 220 and the transfer assembly 300, reducing the space occupied by the air duct and making the overall structure more compact.

[0058] Since the adapter assembly 300 is installed inside the maintenance window 230 of the housing 210, that is, the two sides of the adapter assembly 300 are the first chamber 141a and the second chamber 141b respectively, the adapter assembly 300 can be rotated from the first chamber 141a into the maintenance window 230 or from the second chamber 141b into the maintenance window 230 without restriction.

[0059] Please see Figure 4 In some embodiments, the adapter 300 has a transition duct 325 communicating with the outlet duct 220.

[0060] Since the adapter component 300 occupies the height space of the air duct module 200, in order to minimize the reduction of the length of the outlet air duct 220, a transition air duct 325 can be set in the adapter component 300 to connect with the outlet air duct 220. The transition air duct 325 can be regarded as an extension of the outlet air duct 220 or a part of the outlet air duct 220, so that the cold air will also flow in the transition air duct 325.

[0061] 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 being detachably connected to the housing 210, and a first connecting surface 324 and a transition air duct 325 being disposed on the mounting member 320.

[0062] 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.

[0063] 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.

[0064] 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.

[0065] 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.

[0066] 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.

[0067] Please see Figure 7 and Figure 8 In some embodiments, the mounting component 320 includes a mounting body 322 and a fixing plate 323 disposed on the outer surface of the mounting body 322, a transition air duct 325 disposed on the mounting body 322, a first cover plate detachably connected to the fixing plate 323, and a first connecting surface 324 disposed on the fixing plate 323.

[0068] 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.

[0069] 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.

[0070] 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.

[0071] Since the first connecting surface 324 is disposed on the fixed plate 323, and the first connecting surface 324 needs to contact the second connecting surface 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 disposed with the transition air duct 325 and the outlet air duct 220. Thus, when the first connecting surface 324 needs to contact the second connecting surface 231, the connecting port 323a connects the transition air duct 325 and the outlet air duct 220.

[0072] 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 connection surface 324.

[0073] Since the air outlet duct 220 and the transition duct 325 are connected through the contact of the first connecting surface 324 and the second connecting surface 231, a seal 330 is required between the first connecting surface 324 and the second connecting surface 231 to reduce cold air leakage. Furthermore, the beveled fit between the adapter assembly 300 and the housing 210 itself makes the contact between them tighter, resulting in a better seal and reducing cold air leakage.

[0074] At least a portion of the seal 330 is abutted against the first connecting surface 324. This can mean that the entire seal is abutted against the first connecting surface 324, or that a portion of the seal 330 is abutted against the first connecting surface 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 connecting surface 324 and the second connecting surface 231 to provide a seal.

[0075] Specifically, the seal 330 can be made of PU sponge, and the thickness of the seal 330 can be 2mm to 4mm.

[0076] Please see Figure 5 In some embodiments, both the first connecting surface 324 and the second connecting surface 231 are inclined.

[0077] The inclination angle of the first connecting surface 324 and the second connecting surface 231 is the angle between them and the horizontal plane. It can be understood that the inclination angles of the first connecting surface 324 and the second connecting surface 231 are the same. Since both the first connecting surface 324 and the second connecting surface 231 are inclined, they will slide together during the installation of the adapter component 300. This provides guidance for the installation of the adapter component 300, making its positioning more accurate and the installation smoother.

[0078] Furthermore, the first connecting surface 324 and the second connecting surface 231 are inclined, which facilitates the rotation of the adapter assembly 300 into the inspection window 230. Specifically, with Figure 4 Taking the orientation as an example, the first connecting surface 324 and the second connecting surface 231 are inclined downwards from left to right. When installing the adapter component 300, first position the adapter component 300 on the left side of the inspection window 230, then tilt the adapter component 300 to the left, and finally rotate the adapter component 300 clockwise into the inspection window 230, so that the first connecting surface 324 and the second connecting surface 231 come into contact. During this process, the first connecting surface 324 remains stationary, but rotates relative to the second connecting surface 231. Because the first connecting surface 324 and the second connecting surface 231 are inclined, the first connecting surface 324 will not come into contact with the second connecting surface 231 during the initial rotation, thus avoiding friction and compression. Only after the adapter component 300 is fully installed will the first connecting surface 324 and the second connecting surface 231 slightly compress against each other, thereby reducing the damage to the adapter component 300 and the air duct module 200 during the installation of the adapter component 300.

[0079] Furthermore, when a seal 330 is provided on the first connecting surface 324, if the adapter 300 is directly pushed into the inspection window 230 during installation, the seal 330 is easily squeezed by the second connecting surface 231, affecting the sealing effect. Therefore, the adapter 300 is installed in the inspection window 230 by rotating, which can also reduce the degree of deformation of the seal and ensure the sealing effect.

[0080] Please see Figure 10 and Figure 11 In some embodiments, the chamber 140 has a bottom wall 143 that is angled to the air duct module 200, a portion of the adapter 300 is disposed on the bottom wall 143, and the support platform 600 is mounted on the bottom wall 143. The adapter 300 is rotatable relative to the air duct module 200 about the support platform 600 in the direction from the bottom wall 143 to the air duct module 200, so that the first connecting surface 324 contacts the second connecting surface 231.

[0081] by Figure 4 Taking the orientation as an example, the bottom wall 143 and the support platform 600 are located on the left side of the inspection window 230. The direction from the bottom wall 143 to the air duct module 200 is clockwise. The first connecting surface 324 and the second connecting surface 231 are inclined downward from left to right. When installing the adapter component 300, first make the adapter component 300 located on the left side of the inspection window 230, then tilt the adapter component 300 to the left, and finally rotate the adapter component 300 clockwise into the inspection window 230, so that the first connecting surface 324 and the second connecting surface 231 come into contact.

[0082] Obviously, when it is necessary to remove the adapter assembly 300 from the inspection window 230, simply rotate the adapter assembly 300 counterclockwise around the support platform 600.

[0083] Of course, in other embodiments, the bottom wall 143 and the support platform 600 can also be located on the right side of the inspection window 230, with the direction from the bottom wall 143 to the air duct module 200 being counterclockwise. The first connecting surface 324 and the second connecting surface 231 are inclined downward from right to left. When installing the adapter component 300, the adapter component 300 is first positioned on the right side of the inspection window 230, then the adapter component 300 is tilted to the right, and finally the adapter component 300 is rotated counterclockwise into the inspection window 230, so that the first connecting surface 324 contacts the second connecting surface 231. That is, the adapter component 300 can be installed from the left side or the right side, without any limitation.

[0084] Please see Figure 12 In some embodiments, a support corner 620 is formed between the side 610 of the support platform 600 near the inspection window 230 and the bottom wall 143. The side of the adapter assembly 300 near the support platform 600 has a support plate 315, which is set at an angle to the side 610. The adapter assembly 300 can rotate relative to the air duct module 200 by cooperating with the support plate 315 and the support corner 620.

[0085] The side 610 of the support platform 600 can be vertically positioned relative to the bottom wall 143, thus forming a support corner 620 between the side 610 and the bottom wall 143. When the adapter assembly 300 is installed in the maintenance window 230, the support plate 315 is also angled to the side 610; specifically, the support plate 315 can also be vertically positioned relative to the side 610.

[0086] by Figure 4Taking the orientation as an example, when installing the adapter component 300 into the inspection window 230, the adapter component 300 is first positioned on the left side of the inspection window 230, with the support plate 315 abutting against the support corner 620, and the adapter component 300 is kept tilted to the left. Then, the support plate 315 rotates clockwise along the support corner 620, causing the adapter component 300 to rotate clockwise around the support corner 620 until it enters the inspection window 230, and the first connecting surface 324 contacts the second connecting surface 231. Note that when the support plate 315 abuts against the support corner 620, the adapter component 300 is already tilted to the left, and at this point, the adapter component 300 has not yet entered the inspection window 230.

[0087] Of course, the same principle applies when the adapter component 300 is installed from the right side, which will not be elaborated here.

[0088] In some implementations, the support corner 620 is arc-shaped.

[0089] As the adapter assembly 300 rotates, the support plate 315 also rotates along the support corner 620. Therefore, the support corner 620 is arc-shaped, which facilitates rotational cooperation with the support plate 315.

[0090] In some implementations, the width of the support plate 315 is greater than the height of the support platform 600.

[0091] The width of the support plate 315 is the length of the support plate 315 in the width direction when the adapter assembly 300 is installed in the maintenance window 230, and the height of the support platform 600 is the length of the support platform 600 in the height direction.

[0092] Since the adapter assembly 300 needs to tilt to the left before rotating clockwise and then rotate clockwise into the maintenance window 230, the adapter assembly 300 has two extreme rotation states: horizontal and vertical. When the adapter assembly 300 is in the horizontal state, it is set along the width direction; when the adapter assembly 300 is in the vertical state, it is set along the height direction. The vertical state is the working state of the adapter assembly 300.

[0093] When the adapter component 300 tilts to the left to a horizontal position, it cannot rotate further counterclockwise due to the limitation imposed by the support platform 600. At this time, the support plate 315 is parallel to and fits snugly against the side 610 of the support platform 600. Since the width of the support plate 315 is greater than the height of the support platform 600, meaning that the height of the support plate 315 is greater than the height of the support platform 600 when the adapter component 300 is horizontal, there is no mutual interference between the adapter component 300 and the support platform 600. During the clockwise rotation of the adapter component 300, the support plate 315 and the side 610 of the support platform 600 are set at an angle until the adapter component 300 rotates to its final position. At this point, the support plate 315 is perpendicular to the side 610 of the support platform 600, and the adapter component 300 is in a vertical position.

[0094] The width of the support plate 315 can be 10mm to 15mm. Specifically, the width of the support plate 315 can be 11mm, 12mm, 13mm, or 14mm, and there is no limitation thereto.

[0095] Please see Figure 12 In some embodiments, when the first connecting surface 324 is in contact with the second connecting surface 231, the support plate 315 abuts against the side surface 610.

[0096] When the first connecting surface 324 contacts the second connecting surface 231, the adapter assembly 300 is installed in the inspection window 230. At this time, the support plate 315 is perpendicular to the side 610 of the support platform 600, and the support plate 315 abuts against the side 610. Thus, the support part can stop the adapter assembly 300, fixing its position. Of course, this also facilitates the removal of the adapter assembly 300 by rotating it around the support part as a fulcrum, allowing the adapter assembly 300 to be removed from the inspection window 230.

[0097] 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.

[0098] 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.

[0099] Furthermore, since the adapter component 300 is detachable, it is convenient to repair the slide rail 316 when it malfunctions.

[0100] Please see Figure 11 In some embodiments, the refrigeration equipment 10 further includes a damper 400, which is installed on the housing 100. The housing 100 is provided with an air vent 161. The damper 400 can open or close the air vent 161. When the cover plate 310 is removed, the damper 400 can be exposed to the maintenance window 230 through the air vent 161.

[0101] The damper 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 400 can open or close the air vent 161 by rotating it. When the damper 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 400 closes the air vent 161, that is, when the damper 400 covers the air vent 161, the supply air duct 110 and the outlet air duct 220 are separated.

[0102] The damper 400 is also a component that is relatively prone to failure. When the cover plate 310 is removed, the damper 400 can be exposed to the maintenance window 230 through the air vent 161. That is, when the adapter assembly 300 is removed from the maintenance window 230, the air vent 161 will be exposed to the maintenance window 230, and the damper 400 will be exposed to the air vent 161. Thus, maintenance personnel can perform maintenance on the damper 400 through the air vent 161 without disassembling the air duct module 200 and its surrounding components, which greatly saves manpower, material resources and time costs and shortens the maintenance cycle.

[0103] Please see Figure 4In some embodiments, the housing 100 includes a main body 150 and a partition 160. The air duct module 200 is installed on the main body 150. The partition 160 is detachably installed on the main body 150 and located below the maintenance window 230. The air vent 161 is disposed on the partition 160. The damper 400 is installed on the side of the partition 160 away from the maintenance window 230.

[0104] 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 400, it may be necessary to remove the damper 400 from the housing 100 for easier maintenance. Since the separator 160 is detachably installed on the main body 150 and the damper 400 is installed on the separator 160, when the damper 400 needs to be inspected, the separator 160 can be directly removed from the main body 150, thereby removing the damper 400 from the housing 100 for maintenance.

[0105] Specifically, the partition plate has a fixing groove 162 on the side away from the inspection window 230, and the damper 400 is installed in the fixing groove 162 to facilitate the installation or removal of the damper 400. The partition plate can be connected to the main body 150 by bolts to ensure the fixing effect.

[0106] Please see Figure 4 In some embodiments, the housing 100 includes a main body 150 and a partition 160. The air duct module 200 is installed on the main body 150. The partition 160 is detachably installed on the main body 150 and located below the maintenance window 230. The air vent 161 is disposed on the partition 160. The damper 400 is installed on the side of the partition 160 away from the maintenance window 230.

[0107] 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 400, it may be necessary to remove the damper 400 from the housing 100 for easier maintenance. Since the separator 160 is detachably installed on the main body 150 and the damper 400 is installed on the separator 160, when the damper 400 needs to be inspected, the separator 160 can be directly removed from the main body 150, thereby removing the damper 400 from the housing 100 for maintenance.

[0108] Specifically, the partition plate has a fixing groove 162 on the side away from the inspection window 230, and the damper 400 is installed in the fixing groove 162 to facilitate the installation or removal of the damper 400. The partition plate can be connected to the main body 150 by bolts to ensure the fixing effect.

[0109] 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.

[0110] 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.

[0111] 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.
