[0053] The following Figures 1 - 9 will, through specific embodiments and their application scenarios, provide a detailed description of the door body assembly and refrigeration equipment provided by the embodiments of the utility model.

[0054] In the first aspect, as Figure 1 , Figure 4 and Figure 7 shown, the embodiments of the present utility model provide a door body assembly applied to a refrigeration equipment, including: a box door 1, a cabinet door 2, a sliding module 4, a sliding door mechanism 6, and a hanging structure 5;

[0055] The cabinet door 1 is rotatably arranged on the cabinet body 3 of the refrigeration equipment, and the cabinet door 2 is arranged on the side of the cabinet door 1 away from the cabinet body 3; the sliding module 4 includes a slide rail 41, a first slide member 42 and a second slide member 43, the slide rail 41 is arranged on the cabinet door 1 and extends along the width direction of the cabinet door 1; the first slide member 42 and the second slide member 43 are movably arranged on the slide rail 41 respectively, and the first slide member 42 and the second slide member 43 are transmission-connected to move in the opposite direction relative to the slide rail 41;

[0056] The sliding door mechanism 6 is arranged on the box body 3 and connected with the second sliding member 43, so as to drive the second sliding member 43 to move along the slide rail 41 during the opening and closing process of the box door 1; the hanging structure 5 includes a clamping joint 51 and an elastic clamping seat 52, which are respectively arranged on the first sliding member 42 and the cabinet door 2, and the elastic clamping seat 52 has a clamping cavity 5201 and a limiting opening communicating with the clamping cavity 5201, and the clamping joint 51 can be clamped in the clamping cavity 5201 by squeezing the limiting opening; the limiting opening is used to limit the clamping joint 51 in the clamping cavity 5201;

[0057] Among them, the thickness of the cabinet door 1 is 18-60mm, for example, the thickness of the cabinet door 1 can be 18mm, 25mm, 35mm, 50mm, 55mm or 60mm; the thickness of the cabinet door 2 is 12-26mm, for example, the thickness of the cabinet door 2 can be 12mm, 15mm, 20mm or 26mm.

[0058] It is understandable that the door assembly is applied to refrigeration equipment such as refrigerators and freezers, and a hinge 9 is provided on the box body 3 of the refrigeration equipment, and the box door 1 is rotatably connected to the box body 3 through the hinge 9 to realize the opening or closing of the box door 1 relative to the box body 3. The outer side of the box door 1 is provided with a cabinet door 2, which can be a door panel, and the cabinet door 2 and the surrounding cabinets can be made of the same material to ensure that the appearance of the refrigeration equipment is consistent with the surrounding cabinets, so that the refrigeration equipment is better coordinated with the surrounding environment.

[0059] For the sliding module 4, the slide rail 41 can be a parallel rail known in the art, that is, the slide rail 41 includes a first rail and a second rail arranged side by side, the first sliding member 42 is movably arranged on the first rail, and the second sliding member 43 is movably arranged on the second rail.

[0060] The first sliding member 42 and the second sliding member 43 have the same structure, both including a connected ball bracket and an adapter seat; the ball bracket of the first sliding member 42 can be slidably arranged on the first track, and the adapter seat of the first sliding member 42 is connected to the card joint 51 of the hanging structure 5; the ball bracket of the second sliding member 43 can be slidably arranged on the second track, and the adapter seat of the second sliding member 43 is connected to the sliding door mechanism 6.

[0061] The sliding door mechanism 6 can be a connecting rod mechanism or a telescopic rod provided between the box body 3 and the box door 1, and no specific limitation is made thereto, as long as it can drive the second sliding member 43 to move along the slide rail 41 during the opening and closing process of the box door 1.

[0062] A linkage structure can be provided on the slide rail 41 to realize the transmission connection between the first sliding member 42 and the second sliding member 43. In this design, when the second sliding member 43 moves in the extending direction of the slide rail 41 towards the first direction, the second sliding member 43 will drive the first sliding member 42 to move in the extending direction of the slide rail 41 towards the second direction, and the second direction is opposite to the first direction; conversely, when the second sliding member 43 moves in the second direction, it will drive the first sliding member 42 to move in the first direction.

[0063] Since the first sliding member 42 and the second sliding member 43 move in opposite directions relative to the slide rail 41, when the sliding door mechanism 6 drives the second sliding member 43 to move towards the side close to the hinge 9 along the width direction of the box door 1, the first sliding member 42 will drive the cabinet door 2 to move towards the side away from the hinge 9 along the width direction of the box door 1 through the hanging structure 5; conversely, when the sliding door mechanism 6 drives the second sliding member 43 to move towards the side away from the hinge 9 along the width direction of the box door 1, the first sliding member 42 will drive the cabinet door 2 to move towards the side close to the hinge 9 along the width direction of the box door 1 through the hanging structure 5.

[0064] For the hanging structure 5, in order to ensure that the card joint 51 and the elastic card seat 52 are reliably clamped, the hardness of the card joint 51 is greater than that of the elastic card seat 52; for example, the card joint 51 can be made of a stainless steel card joint, and the elastic card seat 52 can be made of a plastic card seat; during the process of the card joint 51 being clamped to the elastic card seat 52, the card joint 51 squeezes the limiting port, causing the limiting port to expand, and the diameter of the limiting port increases to allow the card joint 51 to enter the clamping cavity 5201; after the card joint 51 completely enters the clamping cavity 5201, the limiting port will return to its initial size to prevent the card joint 51 from disengaging from the clamping cavity 5201.

[0065] The shape of the limiting port can be circular, rectangular, triangular, etc., and no specific limitation is made thereto. To prevent the card joint 51 from disengaging from the clamping cavity 5201, the maximum outer diameter of the card joint 51 is greater than the opening size of the limiting port.

[0066] Among them, when the card joint 51 and the elastic card seat 52 are completely clamped, the elastic card seat 52 can be in a deformed state, and at this time, the card joint 51 and the inner wall of the clamping cavity 5201 are clamped in an interference fit manner.

[0067] Of course, in this embodiment, the card connector 51 can also be set to be adapted to the card receiving cavity 5201 on the elastic card seat 52. When the card connector 51 and the elastic card seat 52 are successfully engaged, the elastic card seat 52 can return to its initial state (the state when the card connector 51 is not engaged in the elastic card seat 52). At this time, the card connector 51 is limited within the card receiving cavity 5201 of the elastic card seat 52.

[0068] As can be seen from the above, by providing the sliding module 4 and the hanging structure 5 between the cabinet door 1 and the cabinet door 2, and configuring the sliding door mechanism 6 for the second sliding member 43 that pulls the sliding module 4, when installing the cabinet door 2, the card connector 51 of the hanging structure 5 and the elastic card seat 52 can be respectively arranged on the first sliding member 42 of the sliding module 4 and the cabinet door 2 in advance, and then the slide rail 41 of the sliding module 4 is connected to the cabinet door 1 to complete the installation of the sliding module 4. Then, by controlling the card connector 51 to squeeze the elastic card seat 52, the engagement between the card connector 51 and the elastic card seat 52 can be achieved, thus conveniently completing the installation of the cabinet door 2; during the process of opening or closing the cabinet door 1, by the sliding door mechanism 6 pulling the second sliding member 43 to move relative to the slide rail 41, the first sliding member 42 can be made to move in opposite directions along the slide rail 41, thereby ensuring that the cabinet door 2 moves relative to the cabinet door 1 along the width direction of the cabinet door 1 under the support of the supporting member.

[0069] Furthermore, in practical applications, when the refrigeration device is installed in an embedded manner relative to the cabinet, during the process of opening or closing the cabinet door 1, the cabinet door 2 can be utilized to move relative to the cabinet door 1 along the width direction, avoiding the cabinet door 2 from touching the surrounding cabinets during the opening and closing process of the cabinet door 1, thus meeting the normal opening and closing requirements of the cabinet door 1 of the refrigeration device.

[0070] In some embodiments, as Figure 2 and Figure 4 shown, the card connector 51 is arranged on the side surface of the first sliding member 42 facing the cabinet door 2, and the elastic card seat 52 is arranged on the side surface of the cabinet door 2 facing the first sliding member 42. This design can minimize the installation gap between the cabinet door 1 and the cabinet door 2 as much as possible.

[0071] Among them, the card connector 51 and the first sliding member 42 can be set as an integral structure, and the elastic card seat 52 can be detachably connected to the cabinet door 2 through locking members such as bolts and rivets.

[0072] Of course, in this embodiment, the elastic card seat 52 can also be arranged on the side surface of the first sliding member 42 facing the cabinet door 2, and the card connector 51 can be arranged on the side surface of the cabinet door 2 facing the first sliding member 42.

[0073] In some embodiments, as Figure 3 and Figure 4 shown, the card connector 51 and the limiting port are arranged opposite to each other along the thickness direction of the cabinet door 2, and the card connector 51 is adapted to the card receiving cavity 5201.

[0074] It is understandable that during the installation of the cabinet door 2, the operator can drive the cabinet door 2 in the thickness direction to approach the box door 1 to achieve the clamping between the clamping joint 51 and the elastic clamping seat 52.

[0075] During the clamping of the clamping joint 51 and the elastic clamping seat 52, the clamping joint 51 squeezes the limiting port in the thickness direction of the cabinet door 2, and the limiting port becomes larger under the extrusion of the clamping joint 51 to allow the clamping joint 51 to pass through. After the clamping joint 51 enters the clamping cavity 5201, the limiting port contracts to the initial state. At this time, the clamping joint 51 is limited in the clamping cavity 5201, and the clamping joint 51 and the elastic clamping seat 52 are clamped. Without being subjected to an external force in the thickness direction again, the two are not easily separated.

[0076] In some embodiments, as Figure 4 shown, in order to facilitate the clamping between the clamping joint 51 and the elastic clamping seat 52, the clamping joint 51 includes a spherical head 510, the clamping cavity 5201 includes a spherical cavity, the spherical head 510 is adapted to the spherical cavity, and the diameter of the limiting port is smaller than the diameter of the spherical head 510.

[0077] It is understandable that by designing the clamping cavity 5201 as a spherical cavity, the stability of the structure of the elastic clamping seat 52 can be ensured, so that the elastic clamping seat 52 can smoothly return to the initial state when being squeezed by the spherical head 510 to limit the spherical head 510 in the spherical cavity.

[0078] Among them, the diameter of the spherical head 510 is the same as the inner diameter of the spherical cavity. The spherical head 510 can be designed as 2 / 3 of the whole sphere, and the inner cavity of the spherical cavity is correspondingly designed as 2 / 3 of the whole sphere. The plane where the limiting port is located is perpendicular to the thickness direction of the cabinet door 2.

[0079] In some embodiments, as Figure 3 shown, the elastic clamping seat 52 includes a clamping seat body 521 and a fixing ear 522. The clamping seat body 521 and the fixing ear 522 are connected. The clamping cavity 5201 is arranged in the clamping seat body 521, and the fixing ear 522 is connected to the cabinet door 2.

[0080] Specifically, the fixing ear 522 is provided with a mounting hole, and the fixing ear 522 can be fixed to the cabinet door 2 by a locking bolt or a locking screw passing through the mounting hole.

[0081] Furthermore, in order to ensure that the elastic clamping seat 52 is reliably fixed to the cabinet door 2, the elastic clamping seat 52 includes a plurality of fixing ears 522, and the plurality of fixing ears 522 are arranged around the clamping seat body 521.

[0082] Optionally, at least two fixing ears 522 can be provided, and at least one fixing ear 522 is arranged on the upper side of the clamping seat body 521 in the height direction of the cabinet door 2.

[0083] For example, there are three fixed ears 522. One of the fixed ears 522 is arranged on the upper side of the card seat body 521 along the height direction of the cabinet door 2, and the other two fixed ears 522 are arranged on the left and right sides of the card seat body 521 along the width direction.

[0084] In some embodiments, in order to ensure that the cabinet door 2 is reliably installed on the box door 1, a plurality of card joints 51 are provided on the sliding member, and a plurality of elastic card seats 52 are provided; the plurality of card joints 51 are arranged along the width direction and are arranged opposite to the plurality of elastic card seats 52 one by one.

[0085] In some embodiments, as Figure 1 shown, in order to ensure the stability and reliability of the relative movement of the cabinet door 2 with respect to the box door 1, a plurality of sets of sliding modules 4 and hanging structures 5 are respectively provided and are arranged opposite to each other one by one. A plurality of sets of sliding modules 4 are provided, and the plurality of sets of sliding modules 4 are arranged between the box door 1 and the cabinet door 2. The sliding door mechanism 6 is connected to the second sliding member 43 of one of the plurality of sets of sliding modules 4.

[0086] Specifically, four sets of sliding modules 4 are provided. Two of the sets of sliding modules 4 are arranged along the width direction of the box door 1 and are arranged between the upper end of the box door 1 and the upper end of the cabinet door 2. The other two sets of sliding modules 4 are arranged along the width direction of the box door 1 and are arranged between the lower end of the box door 1 and the lower end of the cabinet door 2.

[0087] In some embodiments, as Figure 1 shown, the box door 1 is provided with a groove 101, and the sliding module 4 is arranged in the groove 101; the door body assembly further includes a decorative member, and the decorative member cover is used to cover the notch end of the groove 101.

[0088] It can be understood that when the cabinet door 2 is installed on the outer side of the box door 1, the sliding module 4 on the box door 1 is connected to the cabinet door 2 through the hanging structure 5. At this time, there is no decorative member at the notch end of the groove 101.

[0089] In some application scenarios, if the cabinet door 2 is no longer installed on the outer side of the box door 1, at this time the sliding module 4 is no longer used. By covering the notch end of the groove 101 with the decorative member, a hidden design of the sliding module 4 can be realized to ensure the aesthetic appearance of the box door 1.

[0090] In some embodiments, as Figure 5 shown, the sliding door mechanism 6 includes: a traction arm, the first end of the traction arm is configured to be rotatably connected to the box body 3, and the second end of the traction arm is rotatably connected to the second sliding member 43.

[0091] It is understandable that the traction arm is curved, and the first end of the traction arm is rotatably connected to the support on the box body 3, and the support is arranged on one side of the hinge 9 between the box door 1 and the box body 3. This design can use the power of opening and closing the box door 1 to force the traction arm to drive the second sliding member 43 to move relative to the slide rail 41 during the opening and closing process of the box door 1.

[0092] During the process of opening the cabinet door 1, the traction arm drives the second sliding member 43 to move toward the side close to the hinge 9, and then the first sliding member 42 drives the cabinet door 2 to move along the width direction toward the side away from the hinge 9 through the hanging structure 5, so that the cabinet door 2 avoids the cabinet on the side of the refrigeration equipment.

[0093] During the closing process of the cabinet door 1, the traction arm drives the second sliding member 43 to move toward the side away from the hinge 9, and then the first sliding member 42 drives the cabinet door 2 to move along the width direction toward the side close to the hinge 9 through the hanging structure 5 until the cabinet door 2 returns to its initial position. During the resetting process of the cabinet door 2, the cabinet door 2 will not touch the cabinet on the side of the refrigeration equipment.

[0094] In some embodiments, Figure 9 As shown, the sliding door mechanism 6 includes: a trigger member and a linear drive member; the trigger member is used to obtain the opening and closing signal of the box door 1; the linear drive member is arranged between the box door 1 and the second sliding member 43, and is connected to the trigger member; wherein the linear drive member is used to drive the second sliding member 43 to move along the slide rail 41 according to the opening and closing signal fed back by the trigger member.

[0095] It is understandable that in order to facilitate the control of the working state of the linear drive member according to the opening and closing signal fed back by the trigger member, the trigger member and the control module can be electrically connected, and the control module and the linear drive member can be electrically connected.

[0096] The triggering element may be a photoelectric switch, which determines the open or closed state of the door 1 by detecting the change in the distance of the door 1 relative to the box body 3. The triggering element may also be an angle sensor, which determines the open or closed state of the door 1 by detecting the change in the angle of the door 1 relative to the box body 3.

[0097] The linear drive member can be a telescopic rod such as a cylinder or an electric push rod. The linear drive member extends along the width direction, a first end of the linear drive member is connected to the door 1, and a second end of the linear drive member is connected to the second sliding member 43.

[0098] Taking the triggering member as an angle sensor as an example, the control of the cabinet door 2 by the linear drive member during the opening and closing process of the cabinet door 1 is described in detail as follows.

[0099] In actual application, the angle sensor is installed on the hinge shaft corresponding to the hinge 9 to monitor the rotation state of the cabinet door 1 relative to the hinge shaft. When the cabinet door 1 is opened, the angle sensor feeds back the door opening signal to the linear drive, and the linear drive drives the second sliding member 43 to move along the width direction toward the direction close to the hinge 9; since the first sliding member 42 and the second sliding member 43 move in opposite directions along the slide rail 41, the first sliding member 42 will drive the cabinet door 2 to move along the width direction of the cabinet door 1 toward the side away from the hinge 9 through the hanging structure 5; when the cabinet door 1 is closed, the angle sensor feeds back the door closing signal to the linear drive, and the linear drive drives the second sliding member 43 to move along the width direction toward the direction away from the hinge 9, and then the first sliding member 42 drives the cabinet door 2 to move along the width direction toward the side close to the hinge 9 through the hanging structure 5.

[0100] Furthermore, as the opening or closing amplitude of the door 1 is different, the angle sensor can also obtain the rotation angle of the door 1, and the linear drive component can determine the preset value of movement according to the rotation angle. In the process of opening the door 1, the travel of the telescopic end of the linear drive component is determined according to the rotation angle of the door 1 when it is opened, and then the linear drive component drives the cabinet door 2 to move a preset distance in the direction away from the hinge 9 through the sliding module 4 to avoid interference between the cabinet door 2 and the external cabinet body; correspondingly, in the process of closing the door 1, the travel of the telescopic end of the linear drive component is determined according to the rotation angle of the door 1 when it is closed, and then the linear drive component drives the cabinet door 2 to move a preset distance in the direction close to the hinge 9 through the sliding module 4 to avoid interference between the cabinet door 2 and the external cabinet body, and finally the cabinet door 2 is reset.

[0101] In some embodiments, Figure 5 As shown, the sliding module 4 also includes: a coupling component 44, which is arranged on the slide rail 41 and is transmission-connected between the first sliding member 42 and the second sliding member 43; wherein the coupling component 44 is used to control the first sliding member 42 and the second sliding member 43 to move in opposite directions relative to the slide rail 41.

[0102] It is understandable that the coupling assembly 44 includes a first traction rope and a second traction rope; the first traction rope is wound around the first end of the slide rail 41, the second traction rope is wound around the second end of the slide rail 41, and the first traction rope, the second sliding member 43, the second traction rope and the first sliding member 42 are connected end to end in sequence to form a ring structure. In this way, when the sliding door mechanism 6 pulls the first sliding member 42 to move along the slide rail 41, the first sliding member 42 and the second sliding member 43 move in opposite directions relative to the slide rail 41.

[0103] Some examples include Figure 6As shown, the coupling component 44 includes a first rack 441, a coupling gear 442, and a second rack 443; the coupling gear 442 is rotatably disposed on the slide rail 41 and is respectively engaged with the first rack 441 and the second rack 443; the first rack 441 is connected to the first slider 42, and the second rack 443 is connected to the second slider 43.

[0104] It can be understood that the coupling gear 442 is rotatably disposed at a set position on the slide rail 41. The first rack 441 and the second rack 443 are spaced apart from each other and are respectively disposed on both sides of the coupling gear 442. The tooth surfaces of the first rack 441 and the second rack 443 are disposed opposite to each other.

[0105] When the second slider 43 drives the second rack 443 to move along the slide rail 41 toward the side close to the hinge 9, the second rack 443 will drive the coupling gear 442 to rotate. Then, based on the meshing setting between the coupling gear 442 and the first rack 441, the first rack 441 drives the first slider 42 to move toward the side away from the hinge 9, thereby realizing the reverse movement of the first slider 42 and the second slider 43 relative to the slide rail 41.

[0106] In a third aspect, as Figure 7 、 Figure 8 and Figure 9 shown, the embodiment of the present utility model further provides a refrigeration device, including: a box body 3 and the door body assembly described in any one of the above. The box body 3 has a storage compartment, and the box door 1 is rotatably disposed on the box body 3 to open or close the storage compartment.

[0107] It can be understood that the box body 3 can be provided with a plurality of storage compartments, and the plurality of storage compartments are sequentially arranged from top to bottom along the height direction of the box body 3. The box body 3 is configured with a set of door body assemblies for controlling the opening and closing states for each storage compartment. Among them, the box body 3 is provided with a hinge 9 on one side corresponding to each storage compartment, and the box body 3 can be rotatably connected to the box door 1 of the door body assembly corresponding to the storage compartment through the hinge 9.

[0108] For each set of door body assemblies, since the cabinet door 2 can move left and right relative to the box door 1 in the width direction, when the refrigeration device is fully embedded, during the process of opening the box door 1, the cabinet door 2 can be controlled to move away from the hinge 9 relative to the box door 1 to avoid the cabinet around the refrigeration device; during the process of closing the box door 1, the cabinet door 2 is controlled to move toward the side close to the hinge 9 relative to the box door 1 until the cabinet door 2 returns to its original position, ensuring that the side of the box door 1 is flush with the side of the cabinet door 2.

[0109] Since the refrigeration device includes a door body assembly, and the specific structure of the door body assembly refers to the above embodiments, the refrigeration device shown in this embodiment includes all the technical solutions of the above embodiments. Therefore, it has at least all the beneficial effects obtained by all the technical solutions of the above embodiments, which will not be elaborated one by one here.

[0110] In some embodiments, as Figure 8 and Figure 9 shown, the refrigeration device is configured to be disposed in the accommodation space between the first cabinet 7 and the second cabinet 8; during the opening or closing process of the door 1, the sliding door mechanism 6 is used to change the position of the cabinet door 2 on the door 1 so that the cabinet door 2 avoids the first cabinet 7 or the second cabinet 8.

[0111] It can be understood that an opening is provided on the outer side of the accommodation space between the first cabinet 7 and the second cabinet 8, and this design enables the cabinet 3 of the refrigeration device to be integrally embedded in the accommodation space. During the process of the door 1 passing through the opening to control the opening or closing of the accommodation space, the sliding door mechanism 6 is configured to drive the cabinet door 2 to move in the width direction away from or towards the hinge 9. This design can ensure that the cabinet door 2 avoids the side walls of the first cabinet 7 and the second cabinet 8, and prevent the cabinet door 2 from interfering with the side walls of the first cabinet 7 and the second cabinet 8, meeting the requirement that the door 1 can be opened and closed smoothly.

[0112] During the process of opening the door 1, the sliding door mechanism 6 drives the cabinet door 2 to move a preset distance in the width direction away from one side of the hinge 9. In this way, the cabinet door 2 can smoothly avoid the side wall of the second cabinet 8, enabling the door 1 to be fully opened, which is convenient for users to access items.

[0113] Similarly, during the process of closing the door 1, the sliding door mechanism 6 drives the cabinet door 2 to move a preset distance in the width direction towards the side of the hinge 9. When the door 1 is fully closed, the cabinet door 2 will return to its initial position. In this way, the cabinet door 2 can smoothly avoid the side wall of the first cabinet 7, enabling the door 1 to be fully closed, maintaining the overall aesthetics and sealing performance.

[0114] In this embodiment, the cabinet door 2 is movably arranged on the outside of the door 1 along the width direction of the door 1, and the sliding door mechanism 6 is used to drive the cabinet door 2 to move relative to the door 1 during the opening or closing process of the door 1, so that the door 1 can avoid the first cabinet 7 and the second cabinet 8 on the side during the opening and closing processes, preventing interference between the cabinet door 2 and the outside when the door 1 rotates, and meeting the usage requirements of users in different scenarios. This design not only improves the convenience of use but also can prevent possible damage to the door body assembly during use. At the same time, this design also enables the refrigeration device to better integrate into the home environment, achieving the effects of overall aesthetics and sealing.

[0115] In some embodiments, asFigure 8 and Figure 9 As shown in Figure 9 , the door 1 of the box is rotatably connected to the box body 3 through a hinge 9, and the cabinet door 2 can move between a first position and a second position along the width direction relative to the door 1 of the box; when the cabinet door 2 is in the first position, the door 1 of the box closes the storage compartment, and the side of the cabinet door 2 facing the hinge 9 approaches the hinge 9; when the cabinet door 2 is in the second position, the door 1 of the box opens the storage compartment, and the side of the cabinet door 2 facing the hinge 9 moves away from the hinge 9, and the side of the cabinet door 2 and the side of the door 1 of the box are misaligned to avoid the side walls of the first cabinet body 7 or the second cabinet body 8.

[0116] It can be understood that the storage compartment is used to store items to be refrigerated or frozen. When the door 1 of the box closes the storage compartment, the door 1 of the box is in a closed state, and the side of the cabinet door 2 is at a first distance (close to zero) relative to the hinge 9 of the refrigeration device. For example, the side of the cabinet door 2 and the side of the door 1 of the box are flush. At this time, the cabinet door 2 can completely cover the door 1 of the box, ensuring that the cabinet door 2 of the accommodation space exposed by the refrigeration device is consistent with the surrounding first cabinet body 7 and the second cabinet body 8 in appearance.

[0117] When the door 1 of the box opens the storage compartment, the door 1 of the box is in an open state, and the side of the cabinet door 2 is at a second distance (the second distance is greater than the first distance) relative to the hinge 9 of the refrigeration device. For example, the side of the cabinet door 2 and the side of the door 1 of the box 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 2 and the first cabinet body 7 or the second cabinet body 8 caused by the opening of the door 1 of the box.

[0118] 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.
