Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, without contradiction.

[0061] Combine the following Figures 1 to 14 , the door body assembly and refrigeration equipment provided by the embodiment of the utility model are described in detail through specific embodiments and their application scenarios.

[0062] In the first aspect, Figure 1 , Figure 2 , Figure 3 and Figure 12 As shown, an embodiment of the utility model provides a door body assembly, which is applied to refrigeration equipment. The door body assembly includes: a box door 1, a cabinet door 2, a roller assembly 3 and a guide 4.

[0063] The cabinet door 1 is configured to be rotatably disposed on a cabinet body 7 of the refrigeration device, and the cabinet door 2 is disposed on a side of the cabinet door 1 facing away from the cabinet body 7 .

[0064] The roller assembly 3 is disposed on one of the box door 1 and the cabinet door 2 , and the roller assembly 3 includes a roller 31 .

[0065] The guide member 4 is arranged on the other one of the box door 1 and the cabinet door 2, and has a first guide rail 41 and a second guide rail 42. The first guide rail 41 and the second guide rail 42 are arranged at intervals along the height direction of the box door 1 and both extend along the width direction of the box door 1; the roller 31 is rotatably arranged between the first guide rail 41 and the second guide rail 42.

[0066] 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; the cabinet door 2 can be a wooden door panel or a plastic door panel.

[0067] It can be understood that the box body 7 of this embodiment is installed with a hinge 8. The hinge 8 is provided with a hinge shaft, and the box door 1 is rotatably arranged on the hinge shaft to realize the opening or closing of the box door 1 relative to the box body 7. A cabinet door 2 is arranged on the outer side of the box door 1 to ensure that the appearance of the refrigeration device is consistent with the surrounding cabinet bodies, making the coordination between the refrigeration device and the environment better.

[0068] In this embodiment, the roller assembly 3 can be arranged on the box door 1 and the guide member 4 can be arranged on the cabinet door 2, or the roller assembly 3 can be arranged on the cabinet door 2 and the guide member 4 can be arranged on the box door 1. Both of these two designs can realize the sliding of the cabinet door 2 relative to the box door 1.

[0069] Based on the rolling of the roller 31 between the first guide rail 41 and the second guide rail 42, since both the first guide rail 41 and the second guide rail 42 extend along the width direction of the box door 1, therefore, the rolling of the roller 31 with the first guide rail 41 and the second guide rail 42 also extends along the width direction of the box door 1, thereby realizing the movement of the cabinet door 2 relative to the box door 1 along the width direction.

[0070] Furthermore, since the cooperation between the roller assembly 3 and the guide member 4 can realize the sliding of the cabinet door 2 relative to the box door 1, there is no need to additionally arrange a slide rail on the box door 1, reducing the installation space between the cabinet door 2 and the box door 1. Especially in the case where the box door 1 needs to be ultrathinly designed, the ultrathin box door 1 cannot arrange a slide rail. When the space is limited, the roller assembly 3 and the guide member 4 can still be installed between the box door 1 and the cabinet door 2 to realize the movement of the cabinet door 2 relative to the box door 1 in a narrow space.

[0071] For the door body assembly shown in this embodiment, by arranging the roller assembly 3 and the guide member 4 between the box door 1 and the cabinet door 2, the roller assembly 3 includes rollers 31, and the guide member 4 has a first guide rail 41 and a second guide rail 42. Based on the rollers 31 being rollably arranged between the first guide rail 41 and the second guide rail 42 to realize the movement of the cabinet door 2 relative to the box door 1. At the same time, since there is no need to arrange a slide rail on the box door 1, the simple sliding structure of this embodiment can conveniently install the cabinet door 2 on the box door 1, realizing the reduction of the installation gap between the cabinet door 2 and the box door 1 as much as possible, ensuring the aesthetic appearance of the refrigeration device.

[0072] In some embodiments, such as Figure 3As shown, at least one of the first guide rail 41 and the second guide rail 42 abuts against the roller 31 in the thickness direction of the cabinet door 2 to prevent the roller 31 from disengaging between the first guide rail 41 and the second guide rail 42.

[0073] It can be understood that along the thickness direction of the cabinet door 2, the roller 31 can abut against either the first guide rail 41 or the second guide rail 42 to limit the position of the roller 31 during the sliding process, constrain the roller 31 between the first guide rail 41 and the second guide rail 42, and prevent the roller 31 from derailing.

[0074] In this embodiment, both the first guide rail 41 and the second guide rail 42 abut against the roller 31 in the thickness direction of the cabinet door 2 to limit the rolling path of the roller 31. Since both the first guide rail 41 and the second guide rail 42 constrain the roller 31, the roller 31 can slide stably and reliably between the first guide rail 41 and the second guide rail 42.

[0075] In some embodiments, as Figure 3 , Figure 5 , Figure 7 and Figure 12 shown, a groove 311 is provided on the rim of the roller 31, and the groove 311 extends along the circumferential direction of the roller 31; the first guide rail 41 and the second guide rail 42 are respectively embedded in the groove 311.

[0076] It can be understood that the first guide rail 41 and the second guide rail 42 are respectively embedded in the groove 311 from both sides of the roller 31. When the cabinet door 2 moves relative to the box door 1, one end of the first guide rail 41 and the second guide rail 42 extending into the groove 311 guides the roller 31 to roll relative to the first guide rail 41 and the second guide rail 42, and the rolling direction is along the width direction of the box door 1. The groove 311 can ensure that the first guide rail 41 and the second guide rail 42 are stably embedded in the roller 31, and the roller 31 will not fall off from the first guide rail 41 and the second guide rail 42.

[0077] Specifically, the groove 311 can be set as a trapezoidal groove. Correspondingly, the parts of the first guide rail 41 and the second guide rail 42 extending into the groove 311 are set as trapezoidal parts, and the trapezoidal parts are adapted to the trapezoidal groove. The inclined surfaces of the trapezoidal parts are in rolling contact with the inclined surfaces of the trapezoidal groove to ensure the stability of the rolling of the roller 31 relative to the first guide rail 41 and the second guide rail 42.

[0078] In some embodiments, as Figure 5 shown, there are multiple rollers 31, and the multiple rollers 31 are arranged in sequence along the width direction.

[0079] It is understandable that a plurality of rollers 31 are provided along the width direction of the box door 1, and the plurality of rollers 31 are arranged at intervals. The plurality of rollers 31 are all rotatably arranged between the first guide rail 41 and the second guide rail 42, so that the first guide rail 41 and the second guide rail 42 can slide relative to the plurality of rollers 31, making the rolling of the rollers 31 relative to the first guide rail 41 and the second guide rail 42 more stable. The first guide rail 41 and the second guide rail 42 are not prone to tilt during the sliding process, ensuring the reliability of the rolling.

[0080] Specifically, two rollers 31 are provided in this embodiment, and the two rollers 31 are arranged at intervals along the width direction.

[0081] In some embodiments, as Figure 4 shown, the roller assembly 3 further includes: a support member 32.

[0082] The support member 32 is configured to be provided on the end cover 11 of the box door 1, and the roller 31 is rotatably provided on the support member 32.

[0083] It is understandable that the roller assembly 3 is provided on the end cover 11 of the box door 1, and the support member 32 is provided on the end cover 11, which is both connected to the end cover 11 and provides an installation support for the roller 31, enabling the roller 31 to rotate relative to the end cover 11.

[0084] Optionally, the support member 32 can be strip-shaped or plate-shaped like the plate body 43.

[0085] In some embodiments, as Figure 5 shown, the support member 32 includes: a first plate body 321 and a second plate body 322.

[0086] The first plate body 321 is attached to the side surface of the end cover 11, and the roller 31 is rotatably provided on the first plate body 321.

[0087] The second plate body 322 is connected to the first plate body 321 and is attached to the top surface of the end cover 11, and the second plate body 322 is connected to the end cover 11.

[0088] It is understandable that the first plate body 321 and the second plate body 322 of this embodiment are perpendicularly arranged. The second plate body 322 is provided with through holes, and fasteners are used to fix the second plate body 322 to the top surface of the end cover 11. The first plate body 321 is provided with installation holes, and the number of installation holes is the same as the number of rollers 31. The rotating shaft of the roller 31 is inserted into the installation holes and is rotatably provided in the installation holes.

[0089] The first plate body 321 provides an installation support for the roller 31. The second plate body 322 is fixedly connected to the end cover 11. Moreover, the shapes of the first plate body 321 and the second plate body 322 conform to the shape of the end cover 11, saving the installation space between the roller 31 and the end cover 11, achieving a compact connection between the roller 31 and the end cover 11, making the volume of the roller assembly 3 smaller, and being suitable for installation in a narrow space.

[0090] In some embodiments, as Figure 3 shown, the guiding member 4 includes: a plate body 43.

[0091] The plate body 43 is provided with a notch 431 extending in the width direction. The roller 31 is movably disposed in the notch 431 in the width direction. The first guide rail 41 is disposed on the upper side edge of the notch 431, and the second guide rail 42 is disposed on the lower side edge of the notch 431.

[0092] It can be understood that the notch 431 of the plate body 43 is used to accommodate the movement of the roller 31, and the notch 431 divides the plate body 43 into the first guide rail 41 and the second guide rail 42. The first guide rail 41 and the second guide rail 42 are spaced apart by the notch 431. Since the notch 431 does not additionally increase the structure of the plate body 43, the plate body 43 can both accommodate the rolling of the roller 31 and guide the rolling of the roller 31. The structure occupies a small space and realizes the function of guiding the rolling of the roller 31.

[0093] In some embodiments, as Figure 3 shown, the guiding member 4 is an integral sheet metal part.

[0094] It can be understood that the guiding member 4 is made into a sheet metal part by processes such as cutting, forming, and welding a metal plate. Since the overall processing has no splicing structure, the structural strength is relatively high, and the assembly time is reduced, with high production efficiency. A complex structure with a notch 431, a first guide rail 41, and a second guide rail 42 can be designed according to the specific structure of the guiding member 4.

[0095] In some embodiments, as Figure 2 , Figure 6 and Figure 11 shown, it further includes: a limiting member 5. The limiting member 5 is detachably disposed at the open end of the notch 431, and the limiting member 5 is used to limit the roller 31 within the notch 431.

[0096] It can be understood that after the roller 31 is installed in the notch 431, the limiting member 5 is inserted into the open end of the notch 431 to block the open end, so that when the roller 31 rolls to the open end of the notch 431, the limiting member 5 can limit the roller 31 to prevent the roller 31 from disengaging from the notch 431 at the open end, causing the separation of the roller 31 from the cabinet door 2, and ensuring the reliability of the rolling of the roller 31.

[0097] In some embodiments, such as Figure 3 shown, the guide member 4 is provided with a socket 44 and a limiting groove 45, and the socket 44 and the limiting groove 45 are relatively disposed on both sides of the open end.

[0098] The limiting member 5 is inserted through the socket 44, and one end of the limiting member 5 is inserted into the limiting groove 45.

[0099] It can be understood that when the limiting member 5 is installed at the open end of the notch 431, the socket 44 is used to guide the limiting member 5 into the limiting groove 45, and the limiting member 5 is fixed to the guide member 4 by the socket 44 and the limiting groove 45, ensuring that the guide member 4 will not be separated from the limiting member 5.

[0100] Such as Figure 8 、 Figure 9 、 Figure 10 and Figure 11 shown, the installation steps of the door body assembly are as follows:

[0101] First, the guide member 4 is fixed to the cabinet door 2 by fasteners. Then, the second plate body 322 of the roller assembly 3 is attached to the top surface of the end cap 11, and the second plate body 322 and the end cap 11 are fixed by fasteners. The roller 31 on the first plate body 321 faces the guide member 4. Next, the open end of the notch 431 of the guide member 4 is aligned with the roller 31, and the roller 31 is inserted into the notch 431. Finally, the limiting member 5 is inserted into the open end of the guide member 4.

[0102] In some embodiments, such as Figure 13 shown, the door body assembly further includes: a sliding door mechanism 6, and the sliding door mechanism 6 is configured to be disposed on the cabinet body 7 or the cabinet door 1 and is in transmission connection with the cabinet door 2. The sliding door mechanism 6 is used to drive the cabinet door 2 to move relative to the cabinet door 1 in the width direction during the opening and closing process of the cabinet door 1.

[0103] The refrigeration device is configured to be disposed in the accommodation space between the first cabinet body 9 and the second cabinet body 10; during the opening or closing process of the cabinet door 1, the sliding door mechanism 6 is used to change the position of the cabinet door 2 on the cabinet door 1 so that the cabinet door 2 avoids the first cabinet body 9 or the second cabinet body 10.

[0104] It can be understood that an opening is provided on the outer side of the accommodation space between the first cabinet body 9 and the second cabinet body 10. This design enables the refrigeration device to be integrally embedded in the cabinet body. During the process of the cabinet door 1 passing through the opening to control the opening or closing of the accommodation space, the sliding door mechanism is configured to drive the cabinet door 2 to move a preset distance away from or close to the cabinet body 7 on the cabinet door 1 so that the cabinet door 2 avoids the side walls of the first cabinet body 9 and the second cabinet body 10.

[0105] During the process of the cabinet door 1 passing through the opening to control the opening or closing of the accommodation space, the sliding door mechanism is configured to drive the cabinet door 2 to move away from or towards the cabinet body 7 on the cabinet door 1, and can also control the cabinet door 2 to move a preset distance. This design is mainly to avoid interference between the cabinet door 2 and the side walls of the first cabinet body 9 and the second cabinet body 10. Through the movement of the preset distance, the cabinet door 1 can be smoothly opened or closed without colliding or jamming with the side walls of the cabinet body. 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 aesthetics and sealing.

[0106] In some embodiments, as Figure 13 shown, the cabinet door 2 can move between a first position and a second position along the width direction relative to the cabinet door 1.

[0107] When the cabinet door 2 is in the first position, the cabinet door 1 closes the storage compartment, and the side of the cabinet door 2 is close to the hinge 8 between the cabinet door 1 and the cabinet body 7.

[0108] When the cabinet door 2 is in the second position, the cabinet door 1 opens the storage compartment, and the side of the cabinet door 2 is far from the hinge 8 to avoid the side walls of the first cabinet body 9 or the second cabinet body 10.

[0109] It can be understood that the storage compartment is used to store items to be refrigerated or frozen. When the cabinet door 1 closes the storage compartment, the cabinet door 1 is in the closed state, and the side of the cabinet door 2 is at a first distance (close to zero) relative to the hinge 8 of the refrigeration equipment. For example, the side of the cabinet door 2 and the side of the cabinet door 1 are flush. At this time, the cabinet door 2 can completely cover the cabinet door 1, ensuring that the door body of the refrigeration equipment exposed to the accommodation space is consistent with the surrounding first cabinet body 9 and second cabinet body 10 in appearance.

[0110] When the cabinet door 1 opens the storage compartment, the cabinet door 1 is in the 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 8 of the refrigeration equipment. For example, the side walls of the cabinet door 2 and the cabinet door 1 are misaligned and form a gap that can accommodate the side of the first cabinet body 9 or the second cabinet body 10, so as to avoid collision or interference between the cabinet door 2 and the first cabinet body 9 or the second cabinet body 10 caused by the opening of the cabinet door 1.

[0111] In some embodiments, as Figure 13 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 cabinet door 1. The linear drive member is arranged between the cabinet door 1 and the cabinet door 2 and is connected to the trigger member.

[0112] Among them, the linear drive member is used to drive the cabinet door 2 to move along the width direction of the cabinet door 1 according to the opening and closing signal fed back by the trigger member.

[0113] It is understandable that, as Figure 13 shown, a hinge 8 is installed at the vertex of the upper end of the box body. An articulated shaft is provided on the hinge 8, and the box door 1 is rotatably arranged on the articulated shaft to realize the opening or closing of the box door 1 relative to the box body 7.

[0114] The linear driving member is installed on the box door 1, and the output end of the linear driving member is connected to the cabinet door 2. The triggering member is electrically connected to the linear driving member, or the triggering member is wirelessly communicatively connected to the linear driving member.

[0115] This embodiment further includes a controller. The triggering member is electrically connected to the controller, and the controller is electrically connected to the linear driving member. The controller is used to receive the opening and closing signal of the box door 1 fed back by the triggering member and control the linear driving member to drive the movement of the cabinet door 2.

[0116] Specifically, the triggering member can be a photoelectric switch, and the photoelectric switch judges the opening and closing state of the box door 1 by detecting the relative distance between the box door 1 and the box body 7. The triggering member can also be an angle sensor, which judges the opening and closing state of the box door 1 by detecting the relative angle between the box door 1 and the box body 7; the linear driving member can be a cylinder, a hydraulic cylinder, or an electric push rod.

[0117] In practical applications, during the opening process of the box door 1, the linear driving member drives the cabinet door 2 to move away from the hinge 8 along the width direction of the box door 1, that is, move to the left relative to the box door 1, so as to avoid interference between the cabinet door 2 and the cabinet body around the refrigeration equipment; during the closing process of the box door 1, the linear driving member drives the cabinet door 2 to move towards the hinge 8 along the width direction of the box door 1, that is, move to the right relative to the box door 1, so as to ensure that the cabinet door 2 can avoid the cabinet body around the refrigeration equipment when the box door 1 is closed and reset the cabinet door 2.

[0118] For the sliding door mechanism 6 shown in this embodiment, by using the triggering member to obtain the opening and closing signal of the box door 1 and arranging a linear driving member between the box door 1 and the cabinet door 2, when the box door 1 is opened, the linear driving member drives the cabinet door 2 to move away from the hinge 8 along the width direction of the box door 1, so that the cabinet door 2 does not interfere with the cabinet body on the side, and when the box door 1 is closed, the linear driving member drives the cabinet door 2 to move towards the hinge 8 along the width direction of the box door 1, so that the cabinet door 2 returns to its original position, ensuring that the cabinet door 2 does not interfere with the cabinet body around the refrigeration equipment.

[0119] In some embodiments, as Figure 13 shown, the triggering member includes a displacement sensor, and the displacement sensor is used to detect the rotation direction of the box door 1 to obtain the opening and closing signal.

[0120] It is understandable that the displacement sensor can be an angular displacement sensor. The angular displacement sensor in this embodiment is installed on the hinge axis of the hinge 8, and the angular displacement sensor can detect the rotation direction and rotation angle of the door 1 around the hinge axis.

[0121] When the door 1 rotates, the displacement sensor can detect the rotation direction of the door 1 relative to the cabinet body 7. According to the opening and closing states of the door 1, the opening and closing signals are divided into an opening signal and a closing signal; when the door 1 is opened, the displacement sensor feeds back the opening signal to the linear drive member, and the linear drive member drives the cabinet door 2 to move away from the hinge 8 along the width direction of the door 1; correspondingly, when the door 1 is closed, the displacement sensor feeds back the closing signal to the linear drive member, and the linear drive member drives the cabinet door 2 to move towards the hinge 8 along the width direction of the door 1.

[0122] Furthermore, as the opening or closing amplitude of the door 1 is different, the displacement sensor can also obtain the rotation angle of the door 1. The linear drive member can determine the preset value of the movement according to the rotation angle. When the door 1 is in the open state, according to the rotation angle when the door 1 is opened, the stroke of the telescopic end of the linear drive member is determined, and then the linear drive member drives the cabinet door 2 to move a preset distance away from the hinge 8 to avoid interference with the external cabinet body; correspondingly, when the door 1 is in the closed state, according to the rotation angle when the door 1 is closed, the stroke of the telescopic end of the linear drive member is determined, and then the linear drive member drives the cabinet door 2 to move a preset distance towards the hinge 8 to avoid interference between the cabinet door 2 and the external cabinet body, and finally, the cabinet door 2 is reset.

[0123] In this embodiment, by setting the trigger member as a displacement sensor, the opening and closing signal and the rotation angle of the door 1 are obtained synchronously, and then the preset value of the movement of the cabinet door 2 along the width direction of the door 1 is accurately determined, so that the movement of the cabinet door 2 relative to the door 1 can be consistent with the rotation amplitude of the door 1, avoiding interference and ensuring the beauty and reliability of the movement process of the cabinet door 2 relative to the door 1.

[0124] In some embodiments, as Figure 13 shown, the trigger member includes a push-button switch, and the push-button switch is used to receive the pressing input corresponding to the opening and closing signals; the push-button switch is configured to be connected to the opening mechanism that drives the door 1 to open and close.

[0125] It is understandable that the opening mechanism in this embodiment is used to open or close the door 1. The push-button switch is connected to the opening mechanism, and the push-button switch controls the opening mechanism to open or close the door 1 when triggered.

[0126] Generally, built-in refrigerators are designed in a handleless style, using a pressure opening system or a hidden notch to replace the traditional handle. Alternatively, a push-button switch can also be used to control the opening and closing of the door 1 of the built-in refrigerator. The push-button switch in this embodiment is set on the cabinet door of the refrigerator and is used to control the opening and closing of the door 1 by pressing the button of the push-button switch. At the same time, the push-button switch feeds back the opening and closing signals of the door 1 to the linear drive, and the linear drive drives the cabinet door 2 to move along the width direction of the door 1.

[0127] Specifically, after the push-button switch receives the input instruction to open the door 1, the push-button switch feeds back the opening signal to the door opening mechanism and the linear drive. The door opening mechanism drives the door 1 to open. At the same time, the linear drive drives the cabinet door 2 to move along the width direction of the door 1 away from the hinge 8 to ensure that when the door 1 is opened, the cabinet door 2 does not interfere with the surrounding parts.

[0128] After the push-button switch receives the input instruction to close the door 1, the push-button switch feeds back the closing signal to the door opening mechanism and the linear drive. The door opening mechanism drives the door 1 to close. At the same time, the linear drive drives the cabinet door 2 to move along the width direction of the door 1 towards the hinge 8 to ensure that when the door 1 is closed, the cabinet door 2 does not interfere with the surrounding parts, and the cabinet door 2 can be reset as the door 1 is completely closed to ensure the aesthetics of the cabinet door 2.

[0129] In this embodiment, by setting the trigger as a push-button switch, the push-button switch can not only control the opening and closing of the door 1 by the door opening mechanism, but also feed back the opening and closing signals of the door 1 to the linear drive, so that the linear drive drives the cabinet door 2 to move along the width direction of the door 1, enabling the cabinet door 2 to open and close synchronously with the door 1 while avoiding interference with the surrounding cabinet body, ensuring the synchronism and aesthetics of the opening and closing of the door 1 and the cabinet door 2.

[0130] In some embodiments, the linear drive includes a linear motor or a telescopic rod.

[0131] It can be understood that as Figure 13 shown, the linear motor is installed on the door 1, and the output end of the linear motor is connected to the cabinet door 2. The linear motor realizes the movement of the cabinet door 2 along the width direction of the door 1 through linear driving of the cabinet door 2. The reaction speed of the linear motor is fast and the sensitivity is high. For the small-distance movement adjustment of the cabinet door 2 along the door 1, it can quickly respond and accurately adjust the moving distance, realizing the reliability and stability of the movement of the cabinet door 2 relative to the door 1.

[0132] The fixed end of the telescopic rod is connected to the cabinet door 1, and the telescopic end of the telescopic rod is connected to the cabinet door 2. By adjusting the length of the telescopic rod, the distance between the rotation center of the cabinet door 2 and the cabinet door 1 can be adjusted, so as to realize the movement of the cabinet door 2 along the width direction of the cabinet door 1. The telescopic rod is flexible to adjust and saves space, and can flexibly adjust the relative movement between the cabinet door 1 and the cabinet door 2 within the limited space between the cabinet door 1 and the cabinet door 2. Moreover, the design of the telescopic rod is simple and can be coordinated with the overall home environment, improving the consistency of the home environment.

[0133] Specifically, the telescopic rod can be an electric push rod or a cylinder.

[0134] In a second aspect, as Figure 13 and Figure 14 shown, the embodiment of the present invention further provides a refrigeration device, including: a box body 7 and the door body assembly as above. The box body 7 has a storage compartment, and the cabinet door 1 is rotatably arranged on the box body 7 to open or close the storage compartment.

[0135] Specifically, since the refrigeration device includes a door body assembly, and the specific structure of the door body assembly refers to the above embodiment, the refrigeration device shown in this embodiment includes all the technical solutions of the above embodiment. Therefore, it has at least all the beneficial effects obtained by all the technical solutions of the above embodiment, which will not be elaborated herein one by one.

[0136] It can be understood that the cabinet door 1 is used to open and close the storage compartment. When the refrigeration device is fully embedded, in order to keep the consistency between the refrigeration device and the surrounding cabinets, a cabinet door 2 with the same material and color as the surrounding cabinets is installed on the outside of the cabinet door 1.

[0137] The refrigeration device of this embodiment can install the cabinet door 2 on the cabinet door 1 through the roller assembly 3 and the guide member 4, and the cabinet door 2 can be locked on the cabinet door 1, realizing the firm installation of the cabinet door 2 on the cabinet door 1 and reducing the installation gap between the cabinet door and the cabinet door.

[0138] 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 within the scope of the claims of the present invention.
