[0062] The following is combined with Figures 1 - 10, the sliding door mechanism, door body assembly and refrigeration equipment provided by the utility model embodiment are described in detail through specific embodiments and their application scenarios.

[0063] In the first aspect, as Figure 1 , Figure 2 and Figure 3 shown, the utility model embodiment provides a sliding door mechanism, which is applied to a refrigeration equipment. The sliding door mechanism includes: a sliding module 1 and a traction assembly 2;

[0064] The sliding module 1 includes a slide rail 11 and a sliding member 12; the slide rail 11 is configured to be arranged on the door 4 of the refrigeration equipment and extend along the width direction of the door 4; the sliding member 12 is movably arranged on the slide rail 11 and is configured to be connected with the cabinet door 5 of the refrigeration equipment;

[0065] The traction assembly 2 includes a first traction rope 21, a second traction rope 22 and a reversing member 23. The reversing member 23 is connected with the first traction rope 21 and the second traction rope 22, and the first traction rope 21 and the second traction rope 22 are respectively connected with the sliding member 12;

[0066] During the opening or closing process of the door 4, the reversing member 23 is used to change the traction direction of the first traction rope 21 and the second traction rope 22 on the sliding member 12, and then the sliding member 12 drives the cabinet door 5 to move along the width direction.

[0067] It can be understood that the door body assembly is applied to refrigeration equipment such as refrigerators and freezers. A hinge 9 is provided on the box body 6 of the refrigeration equipment, and the door 4 is rotatably connected to the box body 6 through the hinge 9 to realize the opening or closing of the door 4 relative to the box body 6. A cabinet door 5 is provided on the outer side of the door 4 to ensure that the appearance of the refrigeration equipment is consistent with the surrounding cabinets, making the coordination between the refrigeration equipment and the surrounding environment better.

[0068] For the sliding module 1, the slide rail 11 can be in the structure form of a chute, and the sliding member 12 is correspondingly in the structure form of sliding along the chute; the slide rail 11 can also be in the structure form of a slide bar; the sliding member 12 is correspondingly in the structure form of wrapping the slide rail and moving.

[0069] In some examples, the slide rail 11 can be a C-shaped guide rail, the sliding member 12 can be a slider, and at least part of the sliding member 12 is movably arranged in the chute of the C-shaped guide rail along the extension direction of the C-shaped guide rail. The slide rail 11 can be adjustably installed on the door 4 along the width direction and the thickness direction of the door 4 respectively, and the sliding member 12 and the cabinet door 5 are detachably connected.

[0070] For the traction assembly 2, the reversing member 23 can be disposed on the cabinet door 4 or on the slide rail 11. The first ends of the first traction rope 21 and the second traction rope 22 are respectively connected to the reversing member 23. The second end of the first traction rope 21 is connected to one end of the sliding member 12 facing the hinge 9, and the second end of the second traction rope 22 is connected to the other end of the sliding member 12 away from the hinge 9.

[0071] Optionally, the reversing member 23 can be a winch motor. By changing the lengths of the first traction rope 21 and the second traction rope 22 wound or unwound, the traction directions of the first traction rope 21 and the second traction rope 22 on the sliding member 12 can be utilized. Both the first traction rope 21 and the second traction rope 22 can be made of nylon ropes or steel wires.

[0072] Further, during the opening process of the cabinet door 4, the reversing member 23 can wind the second traction rope 22 and unwind the first traction rope 21, so that the traction force of the second traction rope 22 on the sliding member 12 is greater than the traction force of the first traction rope 21 on the sliding member 12. Thus, under the combined traction of the first traction rope 21 and the second traction rope 22, the sliding member 12 drives the cabinet door 5 to move along the width direction away from the hinge 9.

[0073] During the closing process of the cabinet door 4, the reversing member 23 can unwind the second traction rope 22 and wind the first traction rope 21, so that the traction force of the first traction rope 21 on the sliding member 12 is greater than the traction force of the second traction rope 22 on the sliding member 12. Thus, under the combined traction of the first traction rope 21 and the second traction rope 22, the sliding member 12 drives the cabinet door 5 to move along the width direction towards the side close to the hinge 9.

[0074] As can be seen from the above, by providing the sliding module 1 and the traction assembly 2 between the cabinet door 4 and the cabinet door 5, installing the slide rail 11 of the sliding module 1 on the cabinet door 4, and providing guidance for the sliding of the sliding member 12 along the width direction of the cabinet door 4 by the slide rail 11, the traction directions of the first traction rope 21 and the second traction rope 22 on the sliding member 12 can be changed by the reversing member 23, and then the sliding member 12 drives the cabinet door 5 to move along the width direction. In practical applications, when the refrigeration equipment is installed in an embedded manner relative to the cabinet, during the opening or closing process of the cabinet door 4, by using the movement of the cabinet door 5 along the width direction relative to the cabinet door 4, it is possible to prevent the cabinet door 5 from touching the surrounding cabinets during the opening and closing of the cabinet door 4, meeting the normal opening and closing requirements of the cabinet door 4 of the refrigeration equipment.

[0075] In some embodiments, such as Figure 1 、 Figure 2 and Figure 3As shown, the reversing member 23 is configured to be rotatable; the first traction rope 21 is configured to be wound around the box body 6 and connected between the first end of the reversing member 23 and the sliding member 12; the second traction rope 22 is connected between the second end of the reversing member 23 and the sliding member 12;

[0076] When the door 4 is opened, the reversing member 23 rotates in the first rotation direction, and the first traction rope 21 and the second traction rope 22 drive the sliding member 12 to move toward the side away from the hinge 9 of the refrigeration device;

[0077] When the door 4 is closed, the reversing member 23 rotates in the second rotation direction, and the first traction rope 21 and the second traction rope 22 drive the sliding member 12 to move toward the side close to the hinge 9 of the refrigeration device; wherein the first rotation direction and the second rotation direction are opposite.

[0078] It is understandable that the reversing member 23 is configured as a non-powered component, and the reversing member 23 is rotatably disposed on the slide rail 11 .

[0079] At the same time, the hinge 9 includes a main body 901, a fixed shaft 902 and a hinge shaft 903. The main body 901 and the box body 6 of the refrigeration equipment are detachably connected. The fixed shaft 902 and the hinge shaft 903 are respectively connected to the main body 901. The door 4 is rotatably connected to the box body 6 through the hinge shaft 903. The fixed shaft 902 is arranged on one side of the hinge shaft 903 to ensure that the fixed shaft 902 is eccentrically arranged relative to the rotation axis of the door 4.

[0080] In actual application, the first end of the first traction rope 21 is connected to the first end of the reversing member 23, the first traction rope 21 is arranged on the fixed shaft 902, and the second end of the first traction rope 21 is connected to the end of the sliding member 12 facing the hinge 9; the first end of the second traction rope 22 is connected to the second end of the reversing member 23, and the second end of the second traction rope 22 is connected to the end of the sliding member 12 away from the hinge 9. Therefore, based on these connection designs, the first traction rope 21, the sliding member 12, the second traction rope 22 and the reversing member 23 are connected end to end in sequence, and a closed-loop linkage structure is formed.

[0081] like Figure 9 and Figure 10As shown, since the fixed shaft 902 is eccentrically arranged relative to the rotation axis of the cabinet door 4, during the opening process of the cabinet door 4, the distance between the rotation center of the commutation member 23 and the fixed shaft 902 gradually increases, while the total length of the entire annular loop of the above-mentioned closed-loop linkage structure remains unchanged. This will force the commutation member 23 to rotate clockwise relative to the cabinet door 4, which makes the length of the first traction rope 21 between the fixed shaft 902 and the end of the sliding member 12 facing the hinge 9 gradually increase; since the length of the second traction rope 22 remains unchanged, the traction force of the second traction rope 22 on the sliding member 12 is greater than the traction force of the first traction rope 21 on the sliding member 12. Thus, under the combined traction of the first traction rope 21 and the second traction rope 22, the sliding member 12 drives the cabinet door 5 to move along the width direction towards the side away from the hinge 9. During this process, when the opening angle of the cabinet door 4 relative to the cabinet body 6 is θ, the misalignment distance D of the side of the cabinet door 5 facing the hinge 9 relative to the side of the cabinet door 4 facing the hinge 9 is ensured, so as to ensure that the cabinet door 5 can avoid the cabinet on the side of the refrigeration device.

[0082] Correspondingly, during the closing process of the cabinet door 4, the distance between the rotation center of the commutation member 23 and the fixed shaft 902 gradually decreases, while the total length of the entire annular loop of the above-mentioned closed-loop linkage structure remains unchanged. This will force the commutation member 23 to rotate counterclockwise relative to the cabinet door 4, which makes the length of the first traction rope 21 between the fixed shaft 902 and the end of the sliding member 12 facing the hinge 9 gradually decrease; since the length of the second traction rope 22 remains unchanged, the traction force of the second traction rope 22 on the sliding member 12 is less than the traction force of the first traction rope 21 on the sliding member 12. Thus, under the combined traction of the first traction rope 21 and the second traction rope 22, the sliding member 12 drives the cabinet door 5 to move along the width direction towards the side close to the hinge 9. In this case, when the cabinet door 4 is completely closed, the cabinet door 5 is reset, and the side of the cabinet door 5 facing the hinge 9 can be flush with the side of the cabinet door 4 facing the hinge 9 to ensure the aesthetic appearance of the refrigeration device.

[0083] In some embodiments, as Figure 6 shown, the commutation member 23 includes: a connecting portion 231, a first rotating wing 232, and a second rotating wing 233; the connecting portion 231 is rotatably arranged on the slide rail 11; the first rotating wing 232 and the second rotating wing 233 are respectively arranged on opposite sides of the connecting portion 231, the first rotating wing 232 is connected to the first traction rope 21, and the second rotating wing 233 is connected to the second traction rope 22.

[0084] It can be understood that the connecting portion 231 can be configured in a cylindrical shape, and the commutation member 23 can be installed on the slide rail 11 by using a locking bolt passing through the connecting portion 231, and it is ensured that the commutation member 23 can rotate relative to the slide rail 11.

[0085] When the connecting portion 231 is configured as a cylinder, the first rotating wing 232 and the second rotating wing 233 are symmetrically distributed with respect to the central axis of the connecting portion 231. By arranging the first rotating wing 232 and the second rotating wing 233 based on the connecting portion 231, the swing of the first rotating wing 232 and the second rotating wing 233 can be utilized to increase the adjustment range of the first towing rope 21 and the second towing rope 22, which is conducive to ensuring the moving stroke of the sliding member 12.

[0086] In some embodiments, the sliding door mechanism further includes: an elastic member disposed between the sliding member 12 and the slide rail 11; during the opening process of the box door 4, the sliding member 12 is used to stretch or compress the elastic member; during the closing process of the box door 4, the elastic member is used to drive the sliding member 12 to move toward the side of the hinge 9.

[0087] Specifically, by arranging an elastic member between the sliding member 12 and the slide rail 11 and utilizing the elastic force of the elastic member, not only is it ensured that the sliding member 12 moves smoothly on the slide rail 11, but also the first towing rope 21 and the second towing rope 22 are in a tensioned state, which is conducive to adjusting the towing direction of the first towing rope 21 and the second towing rope 22 on the sliding member 12 based on the rotation of the reversing member 23, thereby realizing the control of the sliding member 12 to move along the slide rail 11.

[0088] Meanwhile, during the closing process of the box door 4, the elastic force of the elastic member can also be utilized to drive the sliding member 12 to drive the cabinet door 5 to move toward the side of the hinge 9, ensuring the reliability of the reset of the cabinet door 5.

[0089] Among them, the elastic member can be configured to extend along the width direction of the box door 4, and the elastic member can be a spring.

[0090] In some examples, the elastic member can be arranged between one end of the slide rail 11 away from the hinge 9 and the other end of the slide rail 11 away from the hinge 9; during the opening process of the box door 4, the sliding member 12 moves toward the side of the elastic member to compress the elastic member; during the closing process of the box door 4, the elastic member will recover from the compressed state to the initial state and drive the sliding member 12 to move toward the side of the hinge 9 during this process.

[0091] In some examples, the elastic member can be arranged between one end of the slide rail 11 close to the hinge 9 and the other end of the slide rail 11 close to the hinge 9; during the opening process of the box door 4, the sliding member 12 moves toward the side away from the elastic member to stretch the elastic member; during the closing process of the box door 4, the elastic member will recover from the stretched state to the initial state and drive the sliding member 12 to move toward the side of the hinge 9 during this process.

[0092] In some embodiments, such as Figure 1 and Figure 4As shown, the reversing member 23, the first towing rope 21 and the second towing rope 22 are arranged on the same layer and are located above the sliding module 1.

[0093] Specifically, one end of the sliding member 12 facing the hinge 9 is provided with a first fixing portion 1201, and the second end of the first towing rope 21 is connected to the first fixing portion 1201; the other end of the sliding member 12 facing away from the hinge 9 is provided with a second fixing portion 1202, and the second end of the second towing rope 22 is connected to the second fixing portion 1202.

[0094] Furthermore, both the first fixing portion 1201 and the second fixing portion 1202 can be set as rod-shaped and extend above the sliding module 1. This design can ensure that the reversing member 23, the first towing rope 21 and the second towing rope 22 are arranged on the same layer, which will not affect the normal opening and closing of the box door 4, and can also realize the towing of the sliding member 12.

[0095] In some embodiments, as Figure 1 and Figure 4 shown, the sliding door mechanism further includes: a hanging structure 3, the hanging structure 3 includes a hanging member 31 and a lapping portion, the hanging member 31 is arranged on the cabinet door 5, the lapping portion is arranged on the sliding member 12, and the hanging member 31 is hung on the lapping portion.

[0096] Specifically, the sliding member 12 includes a ball bracket 121 and an adapter seat 122; the ball bracket 121 is movably arranged on the slide rail 11 along the width direction, the adapter seat 122 is connected to the ball bracket 121, the lapping portion is arranged on the adapter seat 122, and the hanging member 31 is detachably connected to the cabinet door 5. Based on this hanging design, the cabinet door 5 can be conveniently hung on the side of the box door 4 facing away from the box body 6, and it is ensured that the cabinet door 5 can move left and right relative to the box door 4 along the width direction.

[0097] Optionally, the lapping portion can be arranged on the side surface of the sliding member 12 facing the cabinet door 5, and the hanging member 31 is arranged on the side surface of the cabinet door 5 facing the sliding member 12. This design can minimize the installation gap between the cabinet door 5 and the box door 4. Among them, the lapping portion can be a hanging structure suitable for hanging the hanging member 31, such as a bayonet, a perforation, a boss, etc.

[0098] Furthermore, the slide rail 11 can be a C-shaped guide rail, and the ball bracket 121 and the slide rail 11 can be in rolling fit by using balls, so that the sliding member 12 can move smoothly relative to the slide rail 11 and there will be no abnormal noise during the movement.

[0099] At the same time, the adapter seat 122 and the ball bracket 121 can be connected by welding, and the adapter seat 122 and the lapping portion can be set as an integral structure, so that there is no need to install the lapping portion in actual application, and it is convenient to support the cabinet door 5 based on the lapping portion.

[0100] Further, along the extending direction of the slide rail 11, the extending length of the ball bracket 121 can be set to be greater than that of the adapter 122. This design can increase the contact area between the ball bracket 121 and the slide rail 11, reduce the contact friction between the ball bracket 121 and the slide rail 11, and thus ensure the stability and reliability of the movement of the sliding member 12 relative to the slide rail 11.

[0101] In some embodiments, as Figure 5 shown, the hanging member 31 includes a fixed seat 311 and a hook 312. The fixed seat 311 is detachably provided on the cabinet door 5 and is connected to the hook 312; the overlapping portion includes a hanging interface 32, and the hook 312 is hung on the hanging interface 32.

[0102] It can be understood that one end of the hook 312 is in a hook shape and is hung in the hanging interface 32, and the other end of the hook 312 is connected to the fixed seat 311; the fixed seat 311 is detachably connected to the cabinet door 5 through a locking member. Among them, the hanging member 31 can be an integral metal member composed of the fixed seat 311 and the hook 312.

[0103] In practical applications, under the action of the gravity of the cabinet door 5, the fixed seat 311 will generate a downward pulling force on the hook 312 to ensure that the hook 312 of the hanging member 31 is reliably hung in the hanging interface 32.

[0104] In some examples, in order to ensure that the hanging member 31 can be adjustably installed on the cabinet door 5, the fixed seat 311 is provided with a plurality of mounting holes, and the fixed seat 311 is connected to the cabinet door 5 through a locking member passing through the mounting holes; among them, at least part of the mounting holes extend in a first direction, and the first direction is perpendicular or inclined to the width direction of the box door 4.

[0105] In some embodiments, as Figure 5 shown, the hanging member 31 further includes a reinforcing rib 313, and the reinforcing rib 313 is provided between the fixed seat 311 and the hook 312.

[0106] It can be understood that by providing the reinforcing rib 313 between the fixed seat 311 and the hook 312, the bonding strength between the fixed seat 311 and the hook 312 can be ensured, and the connection structure failure between the fixed seat 311 and the hook 312 due to excessive force can be prevented.

[0107] Among them, a plurality of reinforcing ribs 313 can be provided, and the plurality of reinforcing ribs 313 are arranged side by side.

[0108] In some embodiments, in order to ensure the structural strength of the hanging member 31, the thickness of the hanging member 31 can also be set to be greater than or equal to 2 mm. For example, the thickness of the hanging member 31 is 2 mm, 2.5 mm, 3 mm or 3.5 mm.

[0109] In some embodiments, asFigure 4 and Figure 5 As shown in Figure 5 , the hanging interface 32 includes a first opening area 321 and a second opening area 322; the first opening area 321 and the second opening area 322 are in communication, and the first opening area 321 is disposed above the second opening area 322 along the height direction of the door 4 of the box.

[0110] The opening width of the first opening area 321 is greater than the opening width of the second opening area 322, and the opening width of the second opening area 322 is adapted to the width of the hook 312. The hook 312 is hung on the lower edge of the second opening area 322.

[0111] It can be understood that when hanging the hanging member 31 into the hanging interface 32, first insert the hook 312 of the hanging member 31 into the first opening area 321, and then control the hook 312 to move from the first opening area 321 to the second opening area 322 until the hook 312 is hung on the lower edge of the second opening area 322 under the gravity of the cabinet door 5.

[0112] Since the opening width of the first opening area 321 is greater than the width of the hook 312, the hook 312 of the hanging member 31 can be conveniently inserted into the first opening area 321; since the opening width of the second opening area 322 is adapted to the width of the hook 312, when the hook 312 is hung on the lower edge of the second opening area 322, the side of the hook 312 will abut against the side wall of the second opening area 322 along the width direction of the door 4 of the box, and the hook 312 will be limited in the second opening area 322 in a vertically distributed hanging posture, ensuring the stability of the hanging posture of the hanging member 31.

[0113] In some embodiments, in order to ensure the stability and reliability of the movement of the cabinet door 5 relative to the door 4 of the box, multiple sets of the sliding module 1 and the hanging structure 3 are respectively provided and are arranged in a one-to-one correspondence. At least one set of the sliding module 1 is disposed between the upper ends of the door 4 of the box and the cabinet door 5, and at least one set of the sliding module 1 is disposed between the lower ends of the door 4 of the box and the cabinet door 5.

[0114] Specifically, four sets of the sliding module 1 are provided, two of which are arranged along the width direction of the door 4 of the box and are disposed between the upper ends of the door 4 of the box and the cabinet door 5, and the other two sets of the sliding module 1 are arranged along the width direction of the door 4 of the box and are disposed between the lower ends of the door 4 of the box and the cabinet door 5.

[0115] In some embodiments, as Figure 7 shown, the door 4 of the box is provided with a groove, and the sliding module 1 is disposed in the groove; the door body assembly further includes a decorative member for covering the notch end of the groove.

[0116] It can be understood that when the cabinet door 5 is installed on the outer side of the door 4 of the box, the sliding module 1 on the door 4 of the box is connected to the cabinet door 5 through the hanging structure 3, and at this time, the decorative member is not installed at the notch end of the groove.

[0117] In some application scenarios, if the cabinet door 5 is no longer installed on the outside of the box door 4, the sliding module 1 is no longer used. By setting a decorative cover on the notch end of the groove, the sliding module 1 can be hidden to ensure the aesthetic appearance of the box door 4.

[0118] In the second aspect, Figure 1 and Figure 7 As shown, the embodiment of the utility model further provides a door assembly, comprising: a box door 4, a cabinet door 5 and a sliding door mechanism as described above;

[0119] The cabinet door 4 is configured to be rotatably arranged on the cabinet body 6 of the refrigeration equipment through at least two hinges 9 to open or close the storage compartment in the cabinet body 6; the cabinet door 5 is arranged on the side of the cabinet door 4 away from the cabinet body 6 and is movably arranged on the cabinet door 4 along the width direction.

[0120] Among them, the thickness of the box door 4 is 18-60mm, for example, the thickness of the box door 4 can be 18mm, 25mm, 35mm, 50mm, 55mm or 60mm; the thickness of the cabinet door 5 is 12-26mm, for example, the thickness of the cabinet door 5 can be 12mm, 15mm, 20mm or 26mm; the cabinet door 5 can be a wooden door panel or a plastic door panel.

[0121] Since the door body assembly includes a sliding door mechanism, the specific structure of the sliding door mechanism refers to the above embodiment, and the door body assembly shown in this embodiment includes all the technical solutions of the above embodiment. Therefore, it has at least all the beneficial effects achieved by all the technical solutions of the above embodiment, which will not be repeated here one by one.

[0122] In the third aspect, Figure 1 , Figure 7 and Figure 8 As shown, the embodiment of the utility model further provides a refrigeration device, comprising: a box body 6 and the door assembly as described above, the box body 6 has a storage compartment, and the box door 4 is rotatably provided on the box body 6 to open or close the storage compartment.

[0123] It is understandable that the box body 6 can be provided with a plurality of storage compartments, which are arranged in sequence from top to bottom along the height direction of the box body 6, and the box body 6 is provided with a set of door body components for controlling the opening and closing state of each storage compartment. Among them, the box body 6 is provided with a hinge 9 on one side corresponding to each storage compartment, and the box body 6 can be rotatably connected with the box door 4 of the door body component corresponding to the storage compartment through the hinge 9.

[0124] For each set of door body components, since the cabinet door 5 can move left and right relative to the box door 4 in the width direction, when the refrigeration device is fully embedded, during the process of opening the box door 4, the traction component 2 can be used to drive the cabinet door 5 to move away from the hinge 9 relative to the box door 4 to avoid the cabinet body around the refrigeration device; during the process of closing the box door 4, the traction component 2 is used to drive the cabinet door 5 to move closer to the hinge 9 relative to the box door 4 until the cabinet door 5 returns to its original position, ensuring that the side of the box door 4 is flush with the side of the cabinet door 5.

[0125] In some embodiments, as Figure 8 , Figure 9 and Figure 10 shown, the refrigeration device is configured to be disposed in the accommodation space between the first cabinet body 7 and the second cabinet body 8; during the process of opening or closing the box door 4, the traction component 2 is used to change the position of the cabinet door 5 on the box door 4 so that the cabinet door 5 can avoid the first cabinet body 7 or the second cabinet body 8 around the refrigeration device.

[0126] It can be understood that there is an opening on the outer side of the accommodation space between the first cabinet body 7 and the second cabinet body 8, and this design enables the refrigeration device to be integrally embedded in the accommodation space. During the process of the box door 4 passing through the opening to control the opening or closing of the accommodation space, the traction component 2 is configured to drive the cabinet door 5 to move away from or closer to the hinge 9 in the width direction. This design can ensure that the cabinet door 5 avoids the side walls of the first cabinet body 7 and the second cabinet body 8 and prevent the cabinet door 5 from interfering with the side walls of the first cabinet body 7 and the second cabinet body 8, meeting the requirement that the box door 4 can be smoothly opened and closed.

[0127] During the process of opening the box door 4, the traction component 2 drives the cabinet door 5 to move a preset distance away from the hinge 9 in the width direction. In this way, the cabinet door 5 can smoothly avoid the side wall of the second cabinet body 8, enabling the box door 4 to be fully opened, facilitating users to access items.

[0128] Similarly, during the process of closing the box door 4, the traction component 2 drives the cabinet door 5 to move a preset distance closer to the hinge 9 in the width direction. When the box door 4 is fully closed, the cabinet door 5 will return to its initial position. In this way, the cabinet door 5 can smoothly avoid the side wall of the first cabinet body 7, enabling the box door 4 to be fully closed, maintaining the overall aesthetics and sealing performance.

[0129] In this embodiment, the cabinet door 5 is movably arranged outside the door 4 of the cabinet along the width direction of the door 4 of the cabinet, and the traction assembly 2 is used to drive the cabinet door 5 to move relative to the door 4 of the cabinet during the opening or closing process of the door 4 of the cabinet, so that the door 4 of the cabinet can avoid the first cabinet body 7 and the second cabinet body 8 on the side during the opening and closing processes, avoiding interference between the cabinet door 5 and the outside when the door 4 of the cabinet rotates, and meeting the usage requirements of users in different scenarios. This design not only improves the convenience of use, but also can avoid possible damage to the door body assembly during use. At the same time, this design also enables the refrigeration equipment to better integrate into the home environment, achieving the effects of overall aesthetics and sealing.

[0130] In some embodiments, as Figure 9 and Figure 10 shown, the cabinet door 5 can move between a first position and a second position relative to the door 4 of the cabinet along the width direction; in the case where the cabinet door 5 is in the first position, the door 4 of the cabinet closes the storage compartment, and the side of the cabinet door 5 facing the hinge 9 approaches the hinge 9; in the case where the cabinet door 5 is in the second position, the door 4 of the cabinet opens the storage compartment, and the side of the cabinet door 5 facing the hinge 9 is away from the hinge 9. At this time, the sides of the cabinet door 5 and the door 4 of the cabinet are misaligned to avoid the side wall of the first cabinet body 7 or the second cabinet body 8.

[0131] It can be understood that the storage compartment is used to store items to be refrigerated or frozen. When the door 4 of the cabinet closes the storage compartment, the door 4 of the cabinet is in the closed state, and the side of the cabinet door 5 is at a first distance (close to zero) relative to the hinge 9 of the refrigeration equipment. For example, the side of the cabinet door 5 and the side of the door 4 of the cabinet are flush. At this time, the cabinet door 5 can completely block the door 4 of the cabinet, ensuring that the door body of the refrigeration equipment exposed in the accommodation space is consistent with the surrounding first cabinet door 5 and second cabinet door 5 in appearance.

[0132] When the door 4 of the cabinet opens the storage compartment, the door 4 of the cabinet is in the open state, and the side of the cabinet door 5 is at a second distance relative to the hinge 9 of the refrigeration equipment. The second distance is represented by D in Figure 10 , and the second distance is greater than the first distance. At this time, the sides of the cabinet door 5 and the door 4 of the cabinet are misaligned, and a gap is formed that can accommodate the side of the first cabinet body 7 or the second cabinet body 8, so as to avoid collision or interference between the cabinet door 5 and the first cabinet body 7 or the second cabinet body 8 caused by the opening of the door 4 of the cabinet.

[0133] Finally, it should be noted that the above embodiments are only used to illustrate the present invention, rather than to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, those of ordinary skill in the art should understand that various combinations, modifications or equivalent replacements of the technical solutions of the present invention do not depart from the spirit and scope of the technical solutions of the present invention, and should all be covered by the scope of the claims of the present invention.
