[0059] Combine the following Figures 1-13 , the door body assembly and refrigeration equipment provided by the utility model embodiment are described in detail through specific embodiments and their application scenarios.

[0060] In the first aspect, Figure 1 , Figure 8 and Figure 11 As shown, the embodiment of the utility model provides a door assembly, which is applied to 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;

[0061] 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;

[0062] The sliding door mechanism 6 is configured to be disposed on the box body 3 and connected to the second sliding member 43, so as to drive the second sliding member 43 to move along the slide rail 41 during the process of opening and closing the box door 1;

[0063] 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. The elastic clamping seat 52 has a clamping groove 520 and a notch 5201 and an embedding opening 5202 communicating with the clamping groove 520, and the notch 5201 and the embedding opening 5202 are connected; the clamping joint 51 can be clamped in the clamping groove 520 from the embedding opening 5202, and one end of the clamping joint 51 away from the elastic clamping seat 52 is inserted into the notch 5201;

[0064] Among them, the thickness of the box door 1 is 18 - 60 mm. For example, the thickness of the box door 1 can be 18 mm, 25 mm, 35 mm, 50 mm, 55 mm or 60 mm; the thickness of the cabinet door 2 is 12 - 26 mm. For example, the thickness of the cabinet door 2 can be 12 mm, 15 mm, 20 mm or 26 mm.

[0065] 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 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. A cabinet door 2 is provided on the outer side of the box door 1. The cabinet door 2 can be a door panel, and the cabinet door 2 and the surrounding cabinet body can adopt the same material to ensure that the appearance of the refrigeration equipment is consistent with the surrounding cabinet body, making the coordination of the refrigeration equipment with the surrounding environment better.

[0066] For the sliding module 4, the slide rail 41 can be a parallel rail well-known in the art, that is, the slide rail 41 includes a first track and a second track arranged side by side. The first sliding member 42 is movably provided on the first track, and the second sliding member 43 is movably provided on the second track.

[0067] The structures of the first sliding member 42 and the second sliding member 43 are the same, and both include a connected ball bracket and an adapter seat; the ball bracket of the first sliding member 42 is slidably provided on the first track, and the adapter seat of the first sliding member 42 is connected to the clamping head 51 of the hanging structure 5; the ball bracket of the second sliding member 43 is slidably provided on the second track, and the adapter seat of the second sliding member 43 is connected to the sliding door mechanism 6. The sliding door mechanism 6 can be a link mechanism or a telescopic mechanism provided between the box body 3 and the box door 1, and no specific limitation is made here, as long as it can drive the second sliding member 43 to move along the slide rail 41 during the opening and closing of the box door 1.

[0068] 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. This design can make the second sliding member 43 drive the first sliding member 42 to move in the second direction along the extension direction of the slide rail 41 when the second sliding member 43 moves in the first direction along the extension direction of the slide rail 41, 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.

[0069] Since the first sliding member 42 and the second sliding member 43 move in opposite directions relative to the sliding rail 41, when the sliding door mechanism 6 drives the second sliding member 43 to move along the width direction of the cabinet door 1 towards the side close to the hinge 9, the first sliding member 42 will drive the cabinet door 2 to move along the width direction of the cabinet door 1 towards the side away from the hinge 9 through the hanging structure 5; conversely, when the sliding door mechanism 6 drives the second sliding member 43 to move along the width direction of the cabinet door 1 towards the side away from the hinge 9, the first sliding member 42 will drive the cabinet door 2 to move along the width direction of the cabinet door 1 towards the side close to the hinge 9 through the hanging structure 5.

[0070] For the hanging structure 5, the elastic clamping seat 52 has a clamping groove 520 adapted to the clamping head 51, and the clamping head 51 can be embedded into the clamping groove 520 through the insertion opening 5202 to achieve the clamping between the clamping head 51 and the elastic clamping seat 52.

[0071] To ensure reliable clamping between the clamping head 51 and the elastic clamping seat 52, the hardness of the clamping head 51 is greater than that of the elastic clamping seat 52; for example, the clamping head 51 can be made of a stainless steel clamping head, and the elastic clamping seat 52 can be made of a plastic clamping seat; the clamping head 51 can be arranged opposite to the insertion opening 5202 along the width direction of the cabinet door 1 to achieve clamping in the clamping groove 520 of the elastic clamping seat 52 along the width direction; the clamping head 51 can also be arranged opposite to the insertion opening 5202 along the thickness direction of the cabinet door 1 to achieve clamping in the clamping groove 520 of the elastic clamping seat 52 along the thickness direction.

[0072] Among them, when the clamping head 51 and the elastic clamping seat 52 are clamped, the elastic clamping seat 52 can be in a deformed state, and at this time, the clamping head 51 and the elastic clamping seat 52 are clamped in an interference fit manner.

[0073] Of course, it is also possible to set the clamping head 51 to be adapted to the clamping groove 520 on the elastic clamping seat 52. When the clamping head 51 and the elastic clamping seat 52 are clamped, the elastic clamping seat 52 can also return to its initial state (the state when the clamping head 51 is not clamped in the elastic clamping seat 52), and at this time, the clamping head 51 is limited in the clamping groove 520 of the elastic clamping seat 52.

[0074] As can be seen from the above, by providing a sliding module 4 and a hanging structure 5 between the cabinet door 1 and the access door 2, and configuring a sliding door mechanism 6 for pulling the second slider 43 of the sliding module 4, when installing the access door 2, the clamping head 51 and the elastic clamping seat 52 of the hanging structure 5 can be respectively arranged on the first slider 42 of the sliding module 4 and the access 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, control the clamping head 51 to enter the clamping groove 520 from the embedding opening 5202, so as to realize the clamping between the clamping head 51 and the elastic clamping seat 52, and thus conveniently complete the installation of the access door 2; during the process of opening or closing the cabinet door 1, by pulling the second slider 43 to move relative to the slide rail 41 through the sliding door mechanism 6, the first slider 42 can be made to move in opposite directions along the slide rail 41, and then the first slider 42 drives the access door 2 to move left and right in the width direction relative to the cabinet door 1 through the hanging structure 5.

[0075] Furthermore, in practical applications, when the refrigeration equipment is installed in an embedded manner relative to the cabinet, during the process of opening or closing the cabinet door 1, the access door 2 can be utilized to move relative to the cabinet door 1 in the width direction, so as to prevent the access door 2 from touching the surrounding cabinets during the opening and closing process of the cabinet door 1, meeting the normal opening and closing requirements of the cabinet door 1 of the refrigeration equipment.

[0076] In some embodiments, as Figure 2 and Figure 4 shown, the clamping head 51 is arranged on one side surface of the first slider 42 facing the access door 2, and the elastic clamping seat 52 is arranged on one side surface of the access door 2 facing the first slider 42. Among them, one end of the clamping head 51 facing the first slider 42 penetrates through the notch 5201; this design not only facilitates the installation of the access door, but also can minimize the installation gap between the cabinet door 1 and the access door 2.

[0077] Among them, the clamping head 51 and the first slider 42 can be set as an integral structure, and the elastic clamping seat 52 can be detachably connected to the access door 2 through locking parts such as bolts and rivets.

[0078] In some embodiments, as Figure 2 、 Figure 3 and Figure 8 shown, both the clamping groove 520 and the notch 5201 extend along the width direction of the cabinet door 1. The embedding opening 5202 is arranged at one end of the clamping groove 520 along the width direction. The clamping head 51 is adapted to the clamping groove 520 and can be clamped in the clamping groove 520 along the width direction; the clamping head 51 is vertically limited between the upper side wall and the lower side wall of the clamping groove 520.

[0079] It is understandable that by setting the clamping groove 520 to extend in the width direction, it is convenient to control the relative movement of the clamping head 51 and the clamping groove 520 in the width direction, so as to realize squeezing the elastic clamping seat 52 by the clamping head 51 in the width direction and then clamping with the elastic clamping seat 52; when the clamping head 51 is clamped in the clamping groove 520, the clamping head 51 is vertically limited between the upper and lower groove walls of the clamping groove 520. This design can prevent the clamping head 51 from disengaging from the clamping groove 520 under the action of vertical pressure or tension, ensuring the reliability of the clamping between the clamping head 51 and the elastic clamping seat 52, so as to use the clamping head 51 and the elastic clamping seat 52 to form a hanging structure 5 to connect the sliding module 4 and the cabinet door 2.

[0080] In the case where the clamping head 51 is fixed on the sliding member 42, one end of the clamping head 51 away from the bottom of the clamping groove 520 is connected to the sliding member 42. By configuring the clamping groove 520 with a notch 5201 and an insertion port 5202, it is convenient to control the clamping head 51 to enter the clamping groove 520 from the insertion port 5202 in the width direction, and it is possible to control the clamping head 51 to move relative to the clamping groove 520 in the width direction until the clamping head 51 is clamped at a set position in the clamping groove 520.

[0081] Optionally, the cross-sectional shape of the clamping head 51 in the vertical plane can be rectangular, and the clamping groove 520 is a rectangular groove adapted to the clamping head 51.

[0082] Optionally, in order to effectively prevent the clamping head 51 from disengaging from the clamping groove 520, the cross-sectional shape of the clamping head 51 in the vertical plane can be an isosceles trapezoid, and the clamping groove 520 is a dovetail groove adapted to the shape of the clamping head 51.

[0083] In some embodiments, as Figure 3 shown, the clamping groove 520 includes a guiding section 5211 and a clamping section 5212; the guiding section 5211 and the clamping section 5212 are communicated; the guiding section 5211 is used to guide the clamping head 51 into the clamping groove 520 and move towards the clamping section 5212; the clamping section 5212 is adapted to the clamping head 51 and is used to realize the clamping of the clamping head 51.

[0084] It is understandable that the clamping groove 520 has a notch 5201 and an insertion port 5202. The guiding section 5211 and the clamping section 5212 can be configured to communicate in the width direction. The notch 5201 extends along the extending direction of the guiding section 5211 and the clamping section 5212. The insertion port 5202 is located at one end of the guiding section 5211 away from the clamping section 5212, and one end of the clamping section 5212 away from the guiding section 5211 can be designed to be sealed.

[0085] As Figure 5As shown, when the clamping connector 51 is clamped into the clamping slot 520, the clamping connector 51 is firstly set at a position corresponding to the embedding opening 5202 of the clamping slot 520, and then moved toward the inside of the clamping slot 520 along the width direction.

[0086] like Figure 6 As shown, the clamping joint 51 is located at the guiding section 5211 of the clamping groove 520 , and at this time, the guiding section 5211 guides the clamping joint 51 to move toward the clamping section 5212 of the clamping groove 520 along the width direction.

[0087] like Figure 7 As shown, as the card connector 51 continues to move forward along the width direction, the card connector 51 reaches the card connector section 5212 of the card connector groove 520. Since the card connector section 5212 is adapted to the card connector 51, the card connector 51 will no longer move relative to the card connector groove 520, thereby completing the card connector 51 based on the card connector groove 520.

[0088] Furthermore, if Figure 3 and Figure 8 As shown, the first end of the guide section 5211 is used for the entry of the card connector 51, and the second end of the guide section 5211 is connected to one end of the card connection section 5212; the slot width of the guide section 5211 gradually decreases from the first end to the second end, and the slot width of the card connection section 5212 is smaller than the slot width of the first end of the guide section 5211, and larger than the slot width of the second end of the guide section 5211.

[0089] It is understandable that the width of the end of the clamping joint 51 facing the first sliding member 42 is smaller than the width of the notch at the first end of the guide section 5211, and larger than the width of the notch at the second end of the guide section 5211. In this way, when the clamping joint 51 moves along the guide section 5211 toward the clamping section 5212, the clamping joint 51 will gradually squeeze the notch 5201 of the guide section 5211 until the clamping joint 51 enters the clamping section 5212.

[0090] Since the clamping section 5212 is adapted to the clamping joint 51, the slot width of the clamping section 5212 is adapted to the width of the end of the clamping joint 51 toward the first sliding member 42. When the clamping joint 51 enters into the clamping section 5212, the clamping joint 51 is limited along the width direction between the end of the clamping section 5212 toward the guide section 5211 and the end of the clamping section 5212 away from the guide section 5211. The clamping joint 51 will not move relative to the clamping section 5212 in both the width direction and the vertical direction.

[0091] In some embodiments, Figure 4 As shown, the elastic base 52 includes a base body 521 and a fixing ear 522 , the base body 521 and the fixing ear 522 are connected, the engaging groove 520 is provided on the base body 521 , and the fixing ear 522 is connected to the cabinet door 2 .

[0092] 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.

[0093] Furthermore, as Figure 4 shown, in order to ensure that the elastic card seat 52 is reliably fixed to the cabinet door 2, multiple fixing ears 522 can be provided on the elastic card seat 52, and the multiple fixing ears 522 are arranged around the card seat body 521.

[0094] 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 card seat body 521 along the height direction of the cabinet door 2.

[0095] For example, three fixing ears 522 are provided, one of the fixing 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 fixing ears 522 are arranged on the left and right sides of the card seat body 521 along the width direction.

[0096] In some embodiments, in order to ensure that the cabinet door 2 is reliably installed on the box door 1, multiple card joints 51 are provided on the first sliding member 42, and multiple elastic card seats 52 are provided; the multiple card joints 51 are arranged in the vertical direction and are arranged opposite to the multiple elastic card seats 52 one by one.

[0097] In some embodiments, as Figure 1 shown, in order to ensure the stability and reliability of the movement of the cabinet door 2 relative to the box door 1, multiple sets of the sliding module 4 and the hanging structure 5 are respectively provided and are arranged opposite to each other one by one. Multiple sets of the sliding module 4 are provided, and the multiple sets of the sliding module 4 are arranged between the box door 1 and the cabinet door 2, and the sliding door mechanism 6 is connected to the second sliding member 43 of one of the multiple sets of the sliding module 4.

[0098] Specifically, four sets of the sliding module 4 are provided, two of the sets of the sliding module 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, and the other two sets of the sliding module 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.

[0099] In some embodiments, as Figure 1 and Figure 11 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.

[0100] 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, and at this time, there is no decorative member at the notch end of the groove 101.

[0101] In some application scenarios, if the cabinet door 2 is no longer installed on the outer side of the box door 1, the sliding module 4 is no longer used at this time. By covering the decorative piece on the notch end of the groove 101, the hidden design of the sliding module 4 can be realized, ensuring the aesthetic appearance of the box door 1.

[0102] In some embodiments, as Figure 9 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.

[0103] It can be understood that the traction arm is bent, and the first end of the traction arm is rotatably connected to the support on the box body 3. The support is arranged on one side of the hinge 9 between the box door 1 and the box body 3. This design can utilize the power when the box door 1 is opened and closed 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.

[0104] During the opening process of the box door 1, the traction arm drives the second sliding member 43 to move towards the side close to the hinge 9, and then the first sliding member 42 drives the cabinet door 2 to move away from the hinge 9 in the width direction through the hanging structure 5, so that the cabinet door 2 avoids the cabinet on the side of the refrigeration device.

[0105] During the closing process of the box door 1, the traction arm drives the second sliding member 43 to move towards the side away from the hinge 9, and then the first sliding member 42 drives the cabinet door 2 to move towards the side close to the hinge 9 in the width direction through the hanging structure 5 until the cabinet door 2 returns to the initial position. And during the reset process of the cabinet door 2, the cabinet door 2 will not touch the cabinet on the side of the refrigeration device either.

[0106] In some embodiments, as Figure 12 and Figure 13 shown, the sliding door mechanism 6 includes: a trigger and a linear drive; the trigger is used to obtain the opening and closing signal of the box door 1; the linear drive is arranged between the box door 1 and the second sliding member 43 and is connected to the trigger; wherein, the linear drive 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.

[0107] It can be understood that in order to facilitate controlling the working state of the linear drive according to the opening and closing signal fed back by the trigger, the trigger can be electrically connected to the control module, and the control module is electrically connected to the linear drive.

[0108] The trigger can be a photoelectric switch, and the photoelectric switch judges the opening and closing state of the box door 1 by detecting the distance change of the box door 1 relative to the box body 3. The trigger can also be an angle sensor, which judges the opening and closing state of the box door 1 by detecting the angle change of the box door 1 relative to the box body 3;

[0109] 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.

[0110] 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.

[0111] 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.

[0112] 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.

[0113] In some embodiments, Figure 9 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.

[0114] It is understandable that the coupling component 44 includes a first drawstring and a second drawstring. The first drawstring is wound around the first end of the slide rail 41, and the second drawstring is wound around the second end of the slide rail 41. The first drawstring, the first sliding member 42, the second drawstring, and the second sliding member 43 are sequentially connected end to end 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 moving directions of the first sliding member 42 and the second sliding member 43 relative to the slide rail 41 are opposite.

[0115] In some examples, such as Figure 10 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 arranged on the slide rail 41 and is respectively meshed with the first rack 441 and the second rack 443; the first rack 441 is connected to the first sliding member 42, and the second rack 443 is connected to the second sliding member 43.

[0116] It is understandable that the coupling gear 442 is rotatably arranged 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 arranged on both sides of the coupling gear 442. The tooth surfaces of the first rack 441 and the second rack 443 are arranged opposite to each other.

[0117] When the second sliding member 43 drives the second rack 443 to move along the slide rail 41 towards 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 of the coupling gear 442 and the first rack 441, the first rack 441 drives the first sliding member 42 to move towards the side away from the hinge 9, so as to realize the reverse movement of the first sliding member 42 and the second sliding member 43 relative to the slide rail 41.

[0118] In a second aspect, as Figure 11 , Figure 12 and Figure 13 shown, the embodiment of the present invention 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 arranged on the box body 3 to open or close the storage compartment.

[0119] It is understandable that the box body 3 can be provided with multiple storage compartments, and the multiple 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.

[0120] For each set of door body components, since the cabinet door 2 can move left and right relative to the box door 1 in the width direction, when the refrigeration equipment 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 body around the refrigeration equipment; during the process of closing the box door 1, the cabinet door 2 is controlled to move closer to the hinge 9 relative to the box door 1 until the cabinet door 2 returns to its original position, ensuring that the side edges of the box door 1 and the cabinet door 2 are flush.

[0121] Since the refrigeration equipment includes a door body component, and the specific structure of the door body component refers to the above-mentioned embodiment, the refrigeration equipment shown in this embodiment includes all the technical solutions of the above-mentioned embodiment. Therefore, it has at least all the beneficial effects obtained by all the technical solutions of the above-mentioned embodiment, which will not be elaborated here one by one.

[0122] In some embodiments, as Figure 12 and Figure 13 shown, the refrigeration equipment 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 1, the sliding door mechanism 6 is used to change the position of the cabinet door 2 on the box door 1 so that the cabinet door 2 can avoid the first cabinet body 7 or the second cabinet body 8.

[0123] It can be understood that an opening is provided 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 cabinet 3 of the refrigeration equipment to be integrally embedded in the accommodation space. During the process of the box 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 closer to the hinge 9. This design can ensure that the cabinet door 2 avoids the side walls of the first cabinet body 7 and the second cabinet body 8, preventing interference between the cabinet door 2 and the side walls of the first cabinet body 7 and the second cabinet body 8, and meeting the requirement that the box door 1 can be smoothly opened and closed.

[0124] During the process of opening the box door 1, the sliding door mechanism 6 drives the cabinet door 2 to move a preset distance in the width direction away from the hinge 9. In this way, the cabinet door 2 can smoothly avoid the side wall of the second cabinet body 8, enabling the box door 1 to be fully opened, which is convenient for users to access items.

[0125] Similarly, during the process of closing the box door 1, the sliding door mechanism 6 drives the cabinet door 2 to move a preset distance in the width direction towards the side close to the hinge 9. When the box 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 body 7, enabling the box door 1 to be fully closed, maintaining the overall aesthetics and sealing performance.

[0126] In this embodiment, the cabinet door 2 is movably arranged outside the door 1 of the refrigerator along the width direction of the door 1 of the refrigerator, and the sliding door mechanism 6 is used to drive the cabinet door 2 to move relative to the door 1 of the refrigerator during the opening or closing of the door 1 of the refrigerator, so that the door 1 of the refrigerator 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 2 and the outside when the door 1 of the refrigerator 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 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 beauty and sealing.

[0127] In some embodiments, as Figure 12 and Figure 13 shown, the door 1 of the refrigerator is rotatably connected to the refrigerator body 3 through a hinge 9, and the cabinet door 2 can move relative to the door 1 of the refrigerator between a first position and a second position along the width direction; in the case where the cabinet door 2 is in the first position, the door 1 of the refrigerator closes the storage compartment, and the side of the cabinet door 2 facing the hinge 9 approaches the hinge 9; in the case where the cabinet door 2 is in the second position, the door 1 of the refrigerator opens the storage compartment, and the side of the cabinet door 2 facing the hinge 9 is away from the hinge 9, and the side of the cabinet door 2 and the side of the door 1 of the refrigerator are misaligned to avoid the side wall of the first cabinet body 7 or the second cabinet body 8.

[0128] It can be understood that the storage compartment is used to store items to be refrigerated or frozen. When the door 1 of the refrigerator closes the storage compartment, the door 1 of the refrigerator 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 equipment. For example, the side of the cabinet door 2 and the side of the door 1 of the refrigerator are flush. At this time, the cabinet door 2 can completely block the door 1 of the refrigerator, ensuring that the cabinet door 2 of the refrigeration equipment exposed in the accommodation space is consistent with the surrounding first cabinet body 7 and second cabinet body 8 in appearance.

[0129] When the door 1 of the refrigerator opens the storage compartment, the door 1 of the refrigerator 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 equipment. For example, the side of the cabinet door 2 and the side of the door 1 of the refrigerator are misaligned, and a gap capable of accommodating the side of the first cabinet body 7 or the second cabinet body 8 is formed, so as to avoid collision or interference between the cabinet door 2 and the first cabinet body 7 or the second cabinet body 8 due to the opening of the door 1 of the refrigerator.

[0130] 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.
