Description

Technical Field

[0001] This utility model relates to the field of refrigeration technology, and in particular to a refrigeration device. Background Technology

[0002] In traditional refrigeration equipment, the installation position of the door is usually fixed. On the one hand, refrigeration equipment with doors opening in different directions requires different molds, which means that two production lines are needed for left-opening and right-opening doors, increasing production costs. On the other hand, users cannot flexibly choose the opening direction according to their actual needs. These limitations restrict the adaptability of refrigeration equipment in different spatial layouts.

[0003] While some refrigeration devices can open to the left and right, these devices often require rotating the door 180 degrees when switching the opening direction. This is not only cumbersome to operate, but also limits the diversity of door appearance design. For example, it is impossible to add decorative effects such as printing to the door because the pattern will be reversed after rotation.

[0004] Especially for some refrigeration equipment that requires additional locking mechanisms to lock the door, it is even more inconvenient to adjust different opening directions. Summary of the Invention

[0005] To address the problem that existing refrigeration equipment cannot meet the requirements of opening doors in different directions, the purpose of this utility model is to provide a refrigeration equipment that can flexibly adjust the opening direction.

[0006] To achieve the above-mentioned objectives, one embodiment of this utility model provides a refrigeration device, comprising:

[0007] The housing encloses a first refrigeration chamber with a first opening, and the housing includes a left mounting part, a right mounting part, a left locking part, and a right locking part;

[0008] The first door body is used to open or close the first opening. The first door body includes a door frame and a left mounting structure, a right mounting structure, a left locking structure and a right locking structure disposed on the door frame.

[0009] A locking assembly, wherein the locking assembly is detachably connected to either the left locking portion or the right locking portion;

[0010] The mounting component is detachably connected to the first door or the housing.

[0011] When the left mounting part and the left mounting structure are hinged together by the mounting assembly, the right locking structure cooperates with the locking assembly to achieve the closing limit of the first door body;

[0012] When the right mounting part and the right mounting structure are hinged together by the mounting assembly, the left locking structure cooperates with the locking assembly to achieve the closing limit of the first door.

[0013] As a further improvement of this utility model, the first door body also includes a left-opening door assembly and a right-opening door assembly, both of which include a driving part and a locking tongue, and the locking assembly includes a latch;

[0014] The latches of the left-opening and right-opening door components respectively cooperate with the latch to achieve the closing limit of the first door body. When the door is opened, the corresponding driving part is driven to release the cooperation between the latch and the latch.

[0015] As a further improvement of this utility model, the driving part includes a handle and a first elastic member. The first elastic member is connected to the handle and the first door body. The first elastic member applies a force to the handle in a first direction to maintain the engagement of the latch and the latch, and applies a force to the handle in the opposite direction to the first direction to release the engagement of the latch and the latch.

[0016] As a further improvement of this utility model, the drive unit further includes a second elastic member, which is connected to the handle and the latch. The second elastic member applies a force to the latch in a first direction to maintain the engagement between the latch and the latch. When the door is closed, the latch pushes up the latch, causing the second elastic member to deform.

[0017] As a further improvement of this utility model, the handle includes a socket, and the tongue of the locking bolt passes through the socket along the first direction. When the locking bolt moves, the tongue moves back and forth within the socket along the first direction.

[0018] As a further improvement of this utility model, the handle includes two insertion holes, the latch includes two tongues, and two latches are provided. The two insertion holes, the two tongues, and the two latches are all arranged sequentially along the first direction.

[0019] As a further improvement of this utility model, the box body is provided with an inner liner, the inner liner surrounds a second refrigeration chamber with a second opening, the refrigeration equipment also includes a second door, the first refrigeration chamber is located inside the second refrigeration chamber, the first opening is located inside the second opening, the first door is located inside the second door, and the left mounting part, the right mounting part, the left locking part and the right locking part are all provided on the inner liner.

[0020] As a further improvement of this utility model, the mounting assembly includes a lower hinge and an upper hinge, the left mounting part includes a lower left mounting part and a upper left mounting part, the right mounting part includes a lower right mounting part and an upper right mounting part, the left mounting structure includes a lower left mounting structure and an upper left mounting structure, and the right mounting structure includes a lower right mounting structure and an upper right mounting structure.

[0021] When the first door is connected to the left side of the box, the lower hinge connects the lower left mounting part and the lower left mounting structure, and the upper hinge connects the upper left mounting part and the upper left mounting structure;

[0022] When the first door is connected to the right side of the box, the lower hinge connects the lower right mounting part and the lower right mounting structure, and the upper hinge connects the upper right mounting part and the upper right mounting structure.

[0023] As a further improvement of this utility model, the upper left mounting part and the upper right mounting part are both configured as a first groove recessed in the top wall of the inner liner, the upper left mounting structure and the upper right mounting structure are configured as a second groove recessed in the top of the door frame, and the two ends of the upper hinge are respectively inserted into the first groove and the second groove.

[0024] As a further improvement of this utility model, the lower left mounting part and the lower right mounting part are both set as fixing holes on the side wall of the inner liner, the lower left mounting structure and the lower right mounting structure are set as a third recessed groove at the bottom of the door frame, the lower hinge includes a mounting hole and a hinge shaft, and the lower hinge is fixedly connected to the inner liner by a connector passing through the mounting hole and the fixing hole in sequence, and the hinge shaft is inserted into the third groove.

[0025] Compared with commonly used technologies, this utility model has the following advantages: The refrigeration equipment has a left mounting part, a right mounting part, a left locking part, and a right locking part on the casing, and corresponding left mounting structures, right mounting structures, left locking structures, and right locking structures on the door. Combined with detachable locking and mounting components, flexible switching of the door's installation position is achieved. Manufacturers or users can choose to install the door on the left or right side of the casing according to actual needs, changing the opening direction without rotating the door. Especially for refrigeration equipment requiring locking structures, the reverse adjustment of the mounting and locking components meets the locking requirements of the door in different directions, greatly improving the adaptability of the refrigeration equipment and the user experience.

[0036] The present invention will now be described in detail with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional modifications made by those skilled in the art based on these embodiments are included within the protection scope of the present invention.

[0037] It should be understood that terms such as “above,” “over,” “below,” and “under” used herein to indicate spatial relative position are for illustrative purposes to describe the relationship of one unit or feature relative to another unit or feature as shown in the accompanying drawings. The terms “spatial relative position” may be intended to include different orientations of the equipment in use or operation other than those shown in the figures.

[0038] One embodiment of this utility model provides a refrigeration device that allows manufacturers or users to flexibly choose the installation position of the door according to their needs, thereby realizing the switching between left and right opening without rotating the door, which significantly improves the practicality of the refrigeration device and the user experience.

[0039] The refrigeration device 100 in this embodiment can be a refrigerator, freezer, upright refrigerator, wine cabinet, etc. The following embodiment will be described using a refrigerator as an example. The refrigerator includes a cabinet 10 and a first door 20.

[0040] like Figure 1 and 2 As shown, the interior of the cabinet 10 forms a first refrigeration chamber 101 with a first opening, which is used to store items that need to be refrigerated or frozen. The first door 20 is used to open or close the first opening.

[0041] To clearly express the position and direction described in this embodiment, in this embodiment, the reference gravity direction is defined as down, the opposite direction is defined as up, the first opening is set to face forward, and the opposite direction is set to back. The user stands in front of the refrigerator to operate the refrigerator, and the corresponding sides are the left and right sides respectively.

[0042] The refrigeration equipment 100 also includes a locking assembly 40 and a mounting assembly 50, both of which are detachable.

[0043] like Figure 3 As shown, the housing 10 of this embodiment includes a left mounting part 12, a right mounting part 13, a left locking part 14 and a right locking part 15, wherein: the left mounting part 12 is located on the left side of the housing 10, and can be a structure such as a mounting hole, groove or protrusion, for connecting with the mounting assembly 50 and supporting the hinged installation of the first door 20 on the left side.

[0044] The right mounting part 13 is located on the right side of the housing 10 and is symmetrically arranged with the left mounting part 12. It can be a structure such as a mounting hole, groove or protrusion, used to support the hinged installation of the first door 20 on the right side.

[0045] The left locking part 14 is located on the left side of the box body 10. It can be a structure such as a buckle, a latch 41 or a groove, and is used to connect with the locking assembly 40 to cooperate with the first door body 20 to achieve the closing limit.

[0046] The right locking part 15 is located on the right side of the housing 10 and is symmetrical to the left locking part 14. It is used to connect with the locking assembly 40 and also realizes the closing limit function of the first door 20.

[0047] The positions of the left mounting part 12 and the right mounting part 13 ensure that the door can be securely hinged, while the structure of the left locking part 14 and the right locking part 15 ensures that the door can be securely locked when closed, preventing accidental opening.

[0048] The first door body 20 includes a door frame 21, and a left mounting structure 22, a right mounting structure 23, a left locking structure 24, and a right locking structure 25 disposed on the door frame 21, as follows: Figure 4 and 5 As shown.

[0049] The door frame 21 is the main frame of the door, and the interior of the door frame 21 is filled with insulation material to improve the insulation performance.

[0050] The left mounting structure 22 is located on the left side of the door frame 21. It can be a mounting hole, groove or protrusion, which cooperates with the left mounting part 12 of the housing 10 for left-side hinged installation.

[0051] The right mounting structure 23 is located on the right side of the door frame 21, symmetrical to the left mounting structure 22, and is used to connect with the right mounting part 13 of the housing 10 to achieve right-side hinged installation.

[0052] The left locking structure 24 is located on the left side of the door frame 21. It can be a latch 243, a buckle, or a protrusion structure, and works with the locking assembly 40 to achieve the closing limit.

[0053] The right locking structure 25 is located on the right side of the door frame 21, symmetrical to the left locking structure 24, and is also used to lock the door in conjunction with the locking assembly 40.

[0054] These structures on the door frame 21 are matched with the corresponding parts on the housing 10, ensuring that the door is both stable and flexible in adjusting the opening direction during installation and use.

[0055] In this embodiment, the locking assembly 40 is detachably connected to either the left locking part 14 or the right locking part 15. The locking assembly 40 can be a latch 41 or a snap-fit ​​structure. The locking assembly 40 cooperates with the locking structure on the door to achieve a limiting function when the door is closed. For example, when the locking assembly 40 is installed on the right locking part 15, it engages with the right locking structure 25 on the door; when the locking assembly 40 is installed on the left locking part 14, it cooperates with the left locking structure 24.

[0056] The mounting component 50 is detachably connected to the first door 20 or the housing 10. The mounting component 50 can be a hinge or other rotating connector, detachably connecting the first door 20 and the housing 10. Depending on the user's installation choice, the mounting component 50 can connect the left mounting part 12 to the left mounting structure 22, or the right mounting part 13 to the right mounting structure 23, thereby achieving hinged installation of the door.

[0057] This embodiment achieves flexible installation and opening / closing of the door on the left or right side through the coordinated action of the housing 10, the door, the locking component 40, and the mounting component 50.

[0058] When the left mounting portion 12 and the left mounting structure 22 are hinged together by the mounting assembly 50, the right locking structure 25 cooperates with the locking assembly 40 to achieve the closing limit of the first door 20. One end of the mounting assembly 50 is fixed to the left mounting portion 12 of the housing 10, and the other end is connected to the left mounting structure 22 of the door, so that the door is connected to the housing 10 by the left hinge and can be opened and closed around the left pivot. The locking assembly 40 is installed on the right locking portion 15 of the housing 10. When the door is closed, the right locking structure 25 (such as the latch 243) on the door engages with the locking assembly 40 (such as the latch 41) on the right locking portion 15 to ensure that the door is firmly locked.

[0059] When the right mounting part 13 and the right mounting structure 23 are hinged together by the mounting assembly 50, the left locking structure 24 cooperates with the locking assembly 40 to achieve the closing limit of the first door 20. One end of the mounting assembly 50 is fixed to the right mounting part 13 of the housing 10, and the other end is connected to the right mounting structure 23 of the door, so that the door is connected to the housing 10 by the right hinge and opens and closes around the right pivot. The locking assembly 40 is installed on the left locking part 14 of the housing 10. When the door is closed, the left locking structure 24 on the door engages with the locking assembly 40 on the left locking part 14 to achieve a stable limit on the door.

[0060] Manufacturers or users can choose to install the door on the left or right side depending on the space layout or personal habits, greatly improving the adaptability of the equipment. For example, in a narrow kitchen, the flexibility of opening the door to the left or right can optimize space utilization.

[0061] Compared to traditional refrigeration equipment where changing the opening direction requires rotating the door, this embodiment allows for switching simply by adjusting the positions of the mounting component 50 and the locking component 40, making operation simpler and saving time and effort. Furthermore, because there is no need to rotate the door, the decorations or patterns on the door always maintain the correct orientation, meeting aesthetic requirements and enhancing the overall quality of the product.

[0062] Especially for the first door 20 without a magnetic door seal, switching the installation position of the mounting component 50 allows the door to be closed tightly on the left or right side, while the existing left and right opening door structure cannot meet the requirements for setting the door to lock.

[0063] In one implementation, such as Figure 4-6 As shown, the first door body 20 also includes a left-opening assembly and a right-opening assembly. Both the left-opening assembly and the right-opening assembly include a drive unit and a latch 243. The locking assembly 40 includes a latch 41.

[0064] The left-opening door assembly and the right-opening door assembly are symmetrically arranged on the left and right sides of the door body, respectively, to control the opening and closing of the door body when the door body is installed on the left or right side of the housing 10.

[0065] The function of the drive unit is to receive the user's operating force and transmit this force to the latch 243 to control the engagement state between the latch 243 and the locking assembly 40. The latch 243 is the component that directly engages with the latch 41 and is responsible for limiting the door when it is closed, ensuring that the door will not be opened accidentally.

[0066] The latches 243 of the left-opening and right-opening door components cooperate with the latches 41 to achieve the closing limit of the first door body 20. When the door is opened, the corresponding driving part is driven to release the cooperation between the latches 243 and the latches 41.

[0067] The locking assembly 40 includes a latch 41, which is mounted on either the left locking portion 14 or the right locking portion 15 of the housing 10, depending on the mounting side of the door. When the door is mounted on the left side, the latch 243 of the right-opening assembly engages with the latch 41 mounted on the right side of the housing 10. When the door is mounted on the right side, the latch 243 of the left-opening assembly engages with the latch 41 mounted on the left side of the housing 10.

[0068] This embodiment features symmetrical door opening components on both sides of the door. Users can choose the installation side as needed without additional replacement or adjustment of the door structure. They can open the door simply by operating the drive unit on the corresponding side. The cooperation between the latch 243 and the latch 41 ensures that the door is securely locked when closed, avoiding the risk of accidental opening.

[0069] like Figure 6 , 7 As shown in Figure 8, the drive unit includes a handle 241 and a first elastic member 242. The first elastic member 242 is connected to the handle 241 and the first door body 20. The first elastic member 242 applies a force to the handle 241 in the first direction T1 to maintain the engagement of the latch 243 and the latch 41. It also applies a force to the handle 241 in the opposite direction to the first direction T1 to release the engagement of the latch 243 and the latch 41.

[0070] The drive unit converts the user's operating force into movement of the latch 243. The handle 241, which the user can grip or press, is installed on the side or top of the door for easy operation; in this embodiment, the first direction T1 can be the downward direction. Figure 5 , 7As shown in Figure 8, a groove 2412 is provided below the handle 241 for the user to hold.

[0071] The first elastic element 242 can be such as a spring or an elastic sheet. The first elastic element 242 ensures that when the door is closed and the user is not operating it, the handle 241 is held in a default position, at which time the latch 243 engages with the latch 41, and the door is locked. The first elastic element 242 applies a force (e.g., a downward force) toward the handle 241 in a first direction T1, causing the handle 241 to exert force on the latch 243, and the latch 243 engages with the latch 41.

[0072] When the user applies a force opposite to the first direction T1 to the handle 241 (e.g., push or pull upwards), the handle 241 moves, causing the latch 243 to retract, releasing the engagement with the latch 41, and the door can then be opened.

[0073] The cooperation between the handle 241 and the first elastic element 242 allows the user to easily disengage the latch 243 from the latch 41 by applying appropriate force when opening the door, making operation convenient. After releasing the handle, the handle 241 and the latch 243 automatically reset, ensuring proper engagement the next time the door is closed, thus improving the convenience of opening and closing the door.

[0074] like Figure 7 , 8 As shown, the drive unit also includes a second elastic member 244, which is connected to the handle 241 and the latch 243. The second elastic member 244 applies a force to the latch 243 in the first direction T1 to maintain the engagement of the latch 243 with the latch 41. When the door is closed, the latch 41 pushes up the latch 243, causing the second elastic member 244 to deform.

[0075] The second elastic element 244 enables the latch 243 to automatically engage with the latch 41 when the door is closed, without relying on the movement of the handle 241. In other words, the second elastic element 244 enables the latch 243 to move independently of the handle 241 during the closing process.

[0076] When the door is close to the closed position, the inclined surface of the latch 243 contacts the latch 41. Then the latch 41 pushes up the latch 243, causing the latch 243 to move upward. At this time, the second elastic element 244 is compressed or stretched and deformed.

[0077] When the latch 243 passes the highest point of the latch 41, the second elastic element 244 releases energy, causing the latch 243 to quickly fall back and engage in the groove of the latch 41, thus achieving the limiting position. During the closing process, the movement of the latch 243 is independent and does not move the handle 241, ensuring smooth closing. Furthermore, because only the latch 243 and the second elastic element 244 move, the overall feedback sound is minimal, reducing noise.

[0078] like Figure 7, 8 As shown, the handle 241 includes a socket 2411, and the tongue 2431 of the latch 243 passes through the socket 2411 along the first direction T1. When the latch 243 moves, the tongue 2431 moves back and forth in the socket 2411 along the first direction T1.

[0079] The socket 2411 provides a movement channel for the tongue 2431 of the latch 243. When opening the door, the user operates the handle 241, which drives the latch 243 to move as a whole. The tongue 2431 moves within the socket 2411 along the first direction T1 (e.g., upward) and retracts to release the engagement with the latch 41. When closing the door, under the action of the second elastic element 244, the tongue 2431 moves within the socket 2411 along the first direction T1 (e.g., downward) and extends to engage with the latch 41.

[0080] The cooperation between the tongue 2431 and the socket 2411 ensures the stability of the movement path of the locking tongue 243 and avoids deviation or jamming.

[0081] In one implementation, such as Figure 7 , 8 As shown, the handle 241 includes two holes 2411, the latch 243 includes two tongues 2431, and two latches 41 are provided. The two holes 2411, the two tongues 2431, and the two latches 41 are all arranged sequentially along the first direction T1 to ensure that when the door is closed, the upper and lower latches 243 can simultaneously engage with the corresponding latches 41.

[0082] Two sockets 2411 are arranged sequentially along the first direction T1 (e.g., downwards). Two tongues 2431 pass through the two sockets 2411 of the handle 241 respectively. Two latches 41 correspond to the two tongues 2431 and are also arranged sequentially along the first direction T1. When the door is opened, the handle 241 simultaneously drives the two tongues 2431 to retract. When the door is closed, the two tongues 2431 simultaneously extend and engage with the latches 41.

[0083] Since both tongues 2431 are controlled by the same locking tongue 243 structure, if an integrated design is adopted, the two tongues 2431 move synchronously when opening and closing the door, ensuring the reliability of locking and the uniformity of sealing. The simultaneous engagement of the two locking tongues 243 disperses the locking force, reducing the force on a single locking tongue 243. Even if one locking tongue 243 malfunctions, the other locking tongue 243 can still keep the door closed, improving security.

[0084] like Figure 1-3As shown, the cabinet 10 is provided with an inner liner 11, which encloses a second refrigeration chamber 102 with a second opening. The refrigeration equipment 100 also includes a second door 30. The first refrigeration chamber 101 is located inside the second refrigeration chamber 102, the first opening is located inside the second opening, the first door 20 is located inside the second door 30, and the left mounting part 12, the right mounting part 13, the left locking part 14 and the right locking part 15 are all provided on the inner liner 11.

[0085] That is, the first refrigeration compartment 101 is a sub-compartment of the second refrigeration compartment 102, the first door 20 is an inner door of the second door 30, the second door 30 is an outer door, and the first opening is located inside the second opening. After the user opens the second door 30, the second refrigeration compartment 102 and the first door 20 are exposed. Then, by opening the first door 20, the first refrigeration compartment 101 can be opened.

[0086] In this way, the refrigeration equipment 100 can provide multiple temperature control zones to meet the storage needs of users for different items, thereby improving the practicality of the equipment. Furthermore, the first refrigeration chamber 101 and the first door 20 are nested within the second refrigeration chamber 102 and the second door 30, which optimizes space utilization and enhances the compactness and aesthetics of the equipment.

[0087] like Figure 3-6 As shown, the mounting assembly 50 includes a lower hinge 51 and an upper hinge 52, the left mounting part 12 includes a lower left mounting part 122 and a upper left mounting part 121, the right mounting part 13 includes a lower right mounting part 132 and a upper right mounting part 131, the left mounting structure 22 includes a lower left mounting structure 222 and a upper left mounting structure 221, and the right mounting structure 23 includes a lower right mounting structure 232 and an upper right mounting structure 231.

[0088] When the first door 20 is connected to the left side of the box 10, the lower hinge 51 connects the lower left mounting part 122 and the lower left mounting structure 222, and the upper hinge 52 connects the upper left mounting part 121 and the upper left mounting structure 221.

[0089] When the first door 20 is connected to the right side of the housing 10, the lower hinge 51 connects the lower right mounting part 132 and the lower right mounting structure 232, and the upper hinge 52 connects the upper right mounting part 131 and the upper right mounting structure 231.

[0090] In other words, when the first door 20 is connected to the left side of the box 10 (inner liner 11):

[0091] Lower hinge 51: connects the lower left mounting part 122 (lower left side of the inner liner 11) and the lower left mounting structure 222 (lower left side of the first door 20).

[0092] Upper hinge 52: connects the upper left mounting part 121 (upper left side of the inner liner 11) and the upper left mounting structure 221 (upper left side of the first door 20).

[0093] When the first door 20 is connected to the right side of the box 10 (inner liner 11):

[0094] Lower hinge 51: connects the lower right mounting part 132 (lower right side of the inner liner 11) and the lower right mounting structure 232 (lower right side of the first door 20).

[0095] Upper hinge 52: connects the upper right mounting part 131 (upper right side of the inner liner 11) and the upper right mounting structure 231 (upper right side of the first door 20).

[0096] In this embodiment, the cooperation of the upper and lower hinges 51 ensures that the first door 20 is subjected to uniform force and moves smoothly during opening and closing. Manufacturers or users can choose the installation side as needed, and only need to adjust the connection position of the hinges, without replacing the door or additional components.

[0097] like Figure 3 As shown, both the upper left mounting portion 121 and the upper right mounting portion 131 are configured as first grooves recessed into the top wall of the inner liner 11, such as... Figure 4 As shown, the upper left mounting structure 221 and the upper right mounting structure 231 are set in the second recess at the top of the door frame 21, and the two ends of the upper hinge 52 are respectively inserted into the first recess and the second recess.

[0098] The two ends of the upper hinge 52 are respectively inserted into the first groove of the inner liner 11 and the second groove of the first door body 20, and are fixed by screws, clips or other fasteners. Specifically, the cylindrical structure can be screwed into the second groove and then inserted into the first groove. This avoids damage to the wall of the inner liner 11 by the screws, ensuring a stable connection, concealed installation to improve the appearance of the equipment, and easy disassembly and assembly, allowing for easy operation when changing the opening direction.

[0099] like Figure 3 and 5 As shown, the lower left mounting part 122 and the lower right mounting part 132 are both set as fixing holes on the side wall of the inner liner 11. The lower left mounting structure 222 and the lower right mounting structure 232 are set as the third recessed groove at the bottom of the door frame 21. The lower hinge 51 includes a mounting hole and a hinge shaft 511. The lower hinge 51 is fixedly connected to the inner liner 11 by a connector passing through the mounting hole and the fixing hole in sequence. The hinge shaft 511 is inserted into the third groove.

[0100] The fixing hole can be a threaded hole or a through hole, used for fixed connection with the lower hinge 51. The mounting hole is used to align with the fixing hole of the inner liner 11 and is fixed by a connector (such as a screw). The connector (such as a screw) passes through the mounting hole of the lower hinge 51 and the fixing hole of the inner liner 11 in sequence to fix the lower hinge 51 to the inner liner 11. The hinge axis 511 of the lower hinge 51 is inserted into the third groove at the bottom of the first door body 20 to ensure that the door body can rotate around the hinge axis 511.

[0101] Other examples Figure 3 As shown, the structures on the side wall of the inner liner 11, such as the lower left mounting part 122, lower right mounting part 132, left locking part 14, and right locking part 15, can be reinforced at the locations where the insulation layer is set between the box body 10 and the inner liner 11, so as to bear the load. When the lower hinge 51 is connected to the lower left mounting part 122 and lower right mounting part 132, and the latch 41 is connected to the left locking part 14 and right locking part 15, they are all connected to these locations where the reinforcement is set, similar to the expansion bolts pre-embedded in the wall, which can bear greater vertical force.

[0102] Compared with the prior art, this embodiment has the following beneficial effects:

[0103] The refrigeration equipment 100 has a left mounting part 12, a right mounting part 13, a left locking part 14, and a right locking part 15 on the housing 10, and corresponding left mounting structures 22, right mounting structures 23, left locking structures 24, and right locking structures 25 on the door. Combined with the detachable locking assembly 40 and mounting assembly 50, the door's installation position can be flexibly switched. Manufacturers or users can choose to install the door on the left or right side of the housing 10 according to actual needs, changing the opening direction without rotating the door. Especially for the refrigeration equipment 100 that requires a locking structure, the reverse adjustment of the mounting assembly 50 and the locking assembly 40 meets the locking requirements of the door in different directions, greatly improving the adaptability and user experience of the refrigeration equipment 100.
