In addition, without conflict, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of different embodiments or examples.

[0059] In an embedded furniture, a refrigeration device may be embedded in a cabinet. Wherein, the door of the refrigeration device is rotatably connected to the cabinet body of the refrigeration device. The door of the refrigeration device can be used to cover the accommodation space inside the cabinet body, and the cabinet door can be used to cover the cabinet body of the cabinet, so as to combine the outer surface of the cabinet with the home decoration style.

[0060] However, as the door of the refrigeration device is opened, the cabinet door is likely to interfere with and collide with the side wall of the cabinet, resulting in a poor user experience of the embedded refrigerator. Therefore, the present application proposes a sliding door mechanism to solve the defect that during the opening process of the door of the refrigeration device, it is likely to interfere with the side wall of the cabinet and affect the user experience.

[0061] The following is combined with Figures 1 to 9, the sliding door mechanism, 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 As shown, an embodiment of the utility model provides a sliding door mechanism, which is applied to a refrigeration device. The refrigeration device includes a box body 9 and a box door 1. The box door 1 is rotatably arranged on the box body 9. The sliding door mechanism includes a hydraulic module 3. The hydraulic module 3 is installed on the box door 1. The hydraulic module 3 has a first piston assembly 33 and a second piston assembly 34 which are linked and arranged along the width direction of the box door 1. The first piston assembly 33 is connected to the box body 9, and the second piston assembly 34 is connected to the cabinet door 2. In the process of opening the cabinet door 1, the first piston assembly 33 fixed on the box body moves in the first direction and drives the second piston assembly 34 to move in the second direction. The second piston assembly moves in the second direction and drives the cabinet door to move in the second direction at the same time. The first direction and the second direction are both along the width direction, and the first direction and the second direction are opposite.

[0063] In the embodiment of the present utility model, Figure 4 As shown, the box body 9 is installed with a hinge 10, and the hinge 10 is provided with a hinge shaft. 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 9.

[0064] The hydraulic module 3 is mounted on the cabinet door 1, and includes a first piston assembly 33 and a second piston assembly 34 which are arranged in reverse linkage, wherein the first piston assembly 33 is connected to the cabinet body 9, and when the cabinet door 1 is opened, it moves in one direction along the width direction of the cabinet door 1. The second piston assembly 34 is connected to the cabinet door 2, and when the cabinet door 1 is opened, it moves in the opposite direction along the width direction of the cabinet door 1.

[0065] When the cabinet door 1 is opened, the connecting rod or other linkage device on the cabinet body 9 drives the first piston assembly 33 to move in one direction. The movement of the first piston assembly 33 compresses the hydraulic oil, causing the hydraulic oil to flow into the second piston assembly 34. After receiving the pressure of the hydraulic oil, the second piston assembly 34 moves in the opposite direction of the first piston assembly 33. Since the second piston assembly 34 is connected to the cabinet door 2, the cabinet door 2 will also move in the second direction with the movement of the second piston assembly 34, thereby avoiding collision with surrounding obstacles.

[0066] When the cabinet door 1 is closed, the above process is performed in reverse. The connecting rod or linkage device drives the first piston assembly 33 to move to the left. The movement of the first piston assembly 33 causes the hydraulic oil to flow back from the second piston assembly 34 to the first piston assembly 33. The second piston assembly 34 is pressed to move to the right, driving the cabinet door 2 to move to the right and return to the initial position.

[0067] The present application can effectively avoid collision by making the cabinet door 2 move laterally when the cabinet door 1 is opened, and the hydraulic system ensures smooth movement, thereby improving the user experience. At the same time, the present application is particularly suitable for kitchen environments with small spaces.

[0068] Specifically, the first direction is a direction approaching the hinge 10 , and the second direction is a direction away from the hinge 10 .

[0069] The present application installs the hydraulic module 3 on the cabinet door 1. The hydraulic module 3 has a first piston assembly 33 and a second piston assembly 34 which are linked and arranged along the width direction of the cabinet door 1. The first piston assembly 33 is connected to the cabinet body 9, and the second piston assembly 34 is connected to the cabinet door 2. When the cabinet door 1 is opened, the first piston assembly 33 fixed on the cabinet body 9 moves in the first direction. While the first piston assembly 33 moves in the first direction, it drives the second piston assembly 34 which is linked and arranged in the opposite direction to move in the second direction. While the second piston assembly 34 moves in the second direction, it drives the cabinet door 2 to move in the second direction, so as to prevent the cabinet door 2 from interfering with the cabinet body on the side. When the cabinet door 1 is closed, while the first piston assembly 33 moves in the opposite direction, it drives the second piston assembly 34 which is linked and arranged in the opposite direction to move in the first direction. The second piston assembly 34 moves in the first direction and drives the cabinet door 2 connected thereto to move in the first direction, so that the cabinet door 2 returns to the initial position. It is ensured that the cabinet door 2 does not interfere with the cabinet body around the refrigeration equipment.

[0070] Furthermore, the door assembly of the present invention is connected to the box door 1 by rotation to the box body 9, and the box door 1 and the cabinet door 2 are connected by a sliding door mechanism. During the opening or closing of the sliding door mechanism, the box door 1 can avoid the cabinets on the side, thereby avoiding the interference of the cabinet door 2 with the surrounding cabinets. Moreover, when the box door 1 is closed, the box door 1 and the cabinet door 2 remain flush, which is aesthetically pleasing.

[0071] Reference Figure 1 In some embodiments, the hydraulic module 3 includes a first hydraulic cylinder 31 and a second hydraulic cylinder 32 , the first hydraulic cylinder 31 and the second hydraulic cylinder 32 are connected, the first piston assembly 33 is disposed in the first hydraulic cylinder 31 , and the second piston assembly 34 is disposed in the second hydraulic cylinder 32 .

[0072] It can be understood that, in this embodiment, the hydraulic module 3 in the sliding door mechanism is composed of two interconnected hydraulic cylinders, and the two hydraulic cylinders are connected through an internal pipe or channel, allowing hydraulic oil to flow between the two hydraulic cylinders.

[0073] A first piston assembly 33 is installed inside the first hydraulic cylinder 31 , and the assembly is connected to the box body 9 . When the box door 1 is opened, the first piston assembly 33 moves inside the first hydraulic cylinder 31 .

[0074] The second hydraulic cylinder 32 is internally equipped with a second piston assembly 34, which is connected to the cabinet door 2. When the box door 1 is pulled open, the second piston assembly 34 will move in the opposite direction within the second hydraulic cylinder 32.

[0075] The connecting pipe is used to connect the first hydraulic cylinder 31 and the second hydraulic cylinder 32, enabling hydraulic oil to flow freely between them.

[0076] When the box door 1 is pulled open, the first piston assembly 33 connected to the box body 9 starts to move in the first direction. The movement of the first piston assembly 33 compresses the hydraulic oil in the first hydraulic cylinder 31, forcing the hydraulic oil to flow through the connecting pipe to the second hydraulic cylinder 32. In the second hydraulic cylinder 32, the pressure generated by the hydraulic oil pushes the second piston assembly 34 to move in the second direction. The movement of the second piston assembly 34 drives the cabinet door 2 to also move in the second direction, thus avoiding collision with the surrounding cabinet bodies.

[0077] When the box door 1 is closed, the above process is executed in reverse. The connecting rod or linkage device drives the first piston assembly 33 to move leftward, and the hydraulic oil flows back from the second hydraulic cylinder 32 to the first hydraulic cylinder 31. The second piston assembly 34 is pressured to move in the first direction, driving the cabinet door 2 to also move rightward and return to the initial position.

[0078] In this way, interference between the cabinet door 2 and the surrounding cabinet bodies is avoided, and when the box door 1 is closed, the box door 1 and the cabinet door 2 are flush, which has aesthetic properties.

[0079] Refer to Figure 1 , in some embodiments, the first piston assembly 33 divides the inner cavity of the first hydraulic chamber into two independent first chamber 311 and second chamber 312;

[0080] The second piston assembly 34 divides the inner cavity of the second hydraulic chamber into two independent third chamber 321 and fourth chamber 322;

[0081] Among them, the first chamber 311 and the third chamber 321 are connected, and the second chamber 312 and the fourth chamber 322 are connected.

[0082] It can be understood that the first hydraulic cylinder 31 is internally equipped with the first piston assembly 33, which divides the inner cavity of the first hydraulic cylinder 31 into the first chamber 311 and the second chamber 312. The first piston assembly 33 is connected to the box body 9.

[0083] The second hydraulic cylinder 32 is internally equipped with the second piston assembly 34, which divides the inner cavity of the second hydraulic cylinder 32 into the third chamber 321 and the fourth chamber 322. The second piston assembly 34 is connected to the cabinet door 2.

[0084] The first channel 6 is used to connect the first chamber 311 and the third chamber 321, and the second channel 7 is used to connect the second chamber 312 and the fourth chamber 322, enabling hydraulic oil to flow between these chambers.

[0085] When the cabinet door 1 is pulled open, the first piston assembly 33 connected to the cabinet body 9 starts to move in the first direction. The movement of the first piston assembly 33 compresses the hydraulic oil in the first chamber 311, forcing the hydraulic oil to flow through the connecting pipe to the third chamber 321. In the second hydraulic cylinder 32, the pressure generated by the hydraulic oil in the third chamber 321 pushes the second piston assembly 34 to move in the second direction, and the movement of the second piston assembly 34 causes the hydraulic oil in the fourth chamber 322 to flow into the second chamber 312. The movement of the second piston assembly 34 drives the cabinet door 2 to move leftward as well, thus avoiding collision with the surrounding cabinet bodies.

[0086] When the cabinet door 1 is closed, the above process is executed in reverse. The connecting rod or linkage device drives the first piston assembly 33 to move leftward, and the hydraulic oil flows back from the third chamber 321 to the first chamber 311. The second piston assembly 34 is pressured to move in the first direction, causing the hydraulic oil in the second chamber 312 to flow into the fourth chamber 322. The movement of the second piston assembly 34 drives the cabinet door 2 to move rightward as well, returning to the initial position.

[0087] Refer to Figure 1 In some embodiments, as shown in, the first hydraulic cylinder 31 and the second hydraulic cylinder are arranged side by side. One end of the first hydraulic cylinder 31 facing the first direction is the first piston rod end, and one end of the second hydraulic cylinder 32 facing the second direction is the second piston rod end.

[0088] It can be understood that arranging the first hydraulic cylinder 31 and the second hydraulic cylinder 32 side by side can save space and is particularly suitable for application scenarios with limited space. The side-by-side arranged hydraulic cylinders are easier to install and maintain because they are arranged in one plane, reducing complexity.

[0089] Refer to Figure 1 In some embodiments, as shown in, a first connecting rod assembly 4 is further included. The first end of the first connecting rod assembly 4 is rotatably connected to the first piston assembly 33, and the second end of the first connecting rod is fixedly connected to the cabinet body 9.

[0090] It can be understood that in this embodiment, the movement of the cabinet body 9 is converted into the linear movement of the first piston assembly 33 by using the first connecting rod assembly 4, and then the lateral movement of the second piston assembly 34 and the cabinet door 2 is driven through the hydraulic system. This not only improves the safety and convenience of users but also increases the practicality and aesthetics of household products.

[0091] Specifically, the first link assembly 4 includes a first rod body 41 and a second rod body 42. The first rod body 41 is fixedly connected to the cabinet body 9. One end of the second rod body 42 is rotatably connected to the first rod body 41, and the other end is rotatably connected to the first piston assembly 33. In this embodiment, the movement of the cabinet body 9 is converted into the linear movement of the first piston assembly 33 by using the first rod body 41 and the second rod body 42 in the first link assembly 4, and then the second piston assembly 34 and the lateral movement of the cabinet door 2 are driven by the hydraulic system. This not only improves the safety and convenience of the user, but also increases the practicality and aesthetic degree of the household product.

[0092] Referring to Figure 1 , in some embodiments, it further includes a second link assembly 5. The second link assembly 5 is bent. The first end of the second link assembly 5 is fixedly connected to the second piston assembly 34, and the second end of the second link assembly 5 is fixedly connected to the cabinet door 2.

[0093] In some embodiments, as Figures 3 to 8 shown, the sliding door mechanism further includes a sliding module 8.

[0094] The sliding module 8 is configured to be disposed between the cabinet door 1 and the cabinet door 2. The sliding module 8 is used to guide the cabinet door 2 to move relative to the cabinet door 1 in the width direction.

[0095] It can be understood that due to the self-weight of the cabinet door 2, the cabinet door 2 may vibrate or tilt during the process of moving relative to the cabinet door 1. The sliding module 8 can provide stable support and guiding functions to guide the reliable and stable movement of the cabinet door 2 relative to the cabinet door 1.

[0096] The sliding module 8 includes a first sliding member 82 and a second sliding member 82. The first sliding member 82 and the second sliding member 82 are slidably engaged in the width direction. The first sliding member 82 can be installed on the cabinet door 1, and the second sliding member 82 can be installed on the cabinet door 2. Alternatively, the first sliding member 82 can be installed on the cabinet door 2, and the second sliding member 82 can be installed on the cabinet door 1. The sliding module 8 realizes the relative movement of the cabinet door 1 and the cabinet door 2 through the relative sliding of the first sliding member 82 and the second sliding member 82.

[0097] In some embodiments, as Figure 4 and Figure 5 shown, the sliding module 8 includes a slide rail 81 and a moving member.

[0098] The slide rail 81 is configured to be disposed on the cabinet door 1 and extend in the width direction.

[0099] The moving member is movably disposed on the slide rail 81 in the width direction, and the moving member is configured to be detachably connected to the cabinet door 2.

[0100] It is understandable that the slide rail 81 can be in the form of a chute, and the moving part is correspondingly in the form of a structure that slides along the chute; the slide rail 81 can also be in the form of a slide bar; the moving part is correspondingly in the form of a structure that wraps the slide rail 81 and moves.

[0101] The moving part can move along the extension direction of the slide rail 81. Based on the guiding and supporting functions of the slide rail 81, the moving part can move stably and reliably along the slide rail 81. Moreover, based on the high rigidity of the slide rail 81, a high straightness can be provided for the moving part, so that the cabinet door 2 can move stably and reliably along the width direction of the box door 1.

[0102] At the same time, the detachable connection between the moving part and the cabinet door 2 facilitates the installation of the cabinet door 2. The detachable connection method improves the versatility and adaptability of the sliding door mechanism, simplifies the manufacturing and assembly processes, and reduces the production cost.

[0103] Optionally, the detachable connection between the moving part and the cabinet door 2 can be achieved by fasteners, or by snap connection, or by magnetic connection.

[0104] In some embodiments, as Figure 3 shown, there are at least two sets of sliding modules 8. The cam assembly is rotatably connected to the driving part, the cam assembly is movably abutted against the sliding part, the elastic part is arranged between the guiding part and the sliding part, and the sliding part is connected to the moving part of one of the at least two sets of sliding modules 8.

[0105] Among them, the cam assembly and the elastic part are used to drive the sliding part to drive the moving part to move along the slide rail 81.

[0106] It is understandable that there can be multiple sets of sliding modules 8. One set of the sliding modules 8 is used to connect to the sliding part, so that the driving part can control the cam assembly to drive the moving part to move along the slide rail 81, and further the driving part can control the cam assembly to drive the cabinet door 2 to move relative to the box door 1 along the extension direction of the slide rail 81. The sliding module 8 connected to the sliding part serves as an active driving mechanism to realize the cooperative design of the driving part and the sliding module 8. For cooperative guiding, the slide rails 81 in each sliding module 8 are arranged in parallel, ensuring that the cabinet door 2 can be accurately guided during the movement process, avoiding interference with the side wall of the cabinet body. Moreover, the remaining multiple sets of sliding modules 8 serve as passive guiding mechanisms. Through the cooperation of the multiple sets of sliding modules 8, the cabinet door 2 can move smoothly and stably relative to the box door 1, improving the convenience and reliability of use, and facilitating the precise control and smooth movement of the cabinet door 2.

[0107] Specifically, there are four sets of sliding modules 8 in this embodiment. Two of the sliding modules 8 are arranged in the width direction and are located 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 8 are arranged in the width direction and are located between the lower end of the box door 1 and the lower end of the cabinet door 2. Moreover, one of the two sets of sliding modules 8 located at the upper end and close to the hinge 10 is connected to the sliding member, and the remaining three sets of sliding modules 8 are respectively arranged at the remaining triangles of the box door 1. The slide rails 81 among the four sets of sliding modules 8 are arranged in parallel.

[0108] Correspondingly, among the three driven sliding modules 8, the sliding module 8 located at the upper end of the box door 1 has the same structure as the sliding module 8 located at the lower end of the box door 1 and is symmetrically arranged on the box door 1.

[0109] In some embodiments, such as Figure 4 and Figure 5 shown, the moving member includes a sliding member 82 and a hanging member 83; the sliding member 82 is movably arranged on the slide rail 81 in the width direction, and the hanging member 83 is configured to be connected to the cabinet door 2 and is hung on the sliding member 82.

[0110] It can be understood that the hanging member 83 is used to connect the sliding member 82 and the cabinet door 2 to realize the movement of the cabinet door 2 relative to the box door 1 driven by the sliding member 82. Moreover, the hanging member 83 is configured to be detachably connected to the cabinet door 2.

[0111] Furthermore, the sliding member 82 of this embodiment includes a sliding body 821 and an adapter seat 822. The sliding body 821 and the adapter seat 822 are fixedly connected. A support frame 811 is provided on the slide rail 81, and a round hole is provided on the support frame 811. A ball is installed in the round hole. The sliding body 821 is in rolling contact with the slide rail 81 to move on the slide rail 81 in the width direction. A first card slot 8221 is provided on the adapter seat 822, and the first card slot 8221 is used to hang the hanging member 83 on the sliding body 821. The relative movement between the sliding body 821 and the slide rail 81 of this embodiment is rolling friction, so as to reduce the frictional force and improve the moving efficiency of the moving member. This design can accurately control the movement track and distance of the cabinet door 2, avoid interference with the side wall of the cabinet body, and realize the smooth opening and closing of the box door 1.

[0112] In some embodiments, such as Figures 4 to 8 shown, the hanging member 83 includes a fixed seat 831 and a hanging part 832; the fixed seat 831 is configured to be connected to the cabinet door 2, and the hanging part 832 is adjustably arranged on the fixed seat 831 in the vertical direction or the horizontal direction, and the hanging part 832 is hung on the sliding member 82.

[0113] It is understandable that a small amount of adjustment in the vertical or horizontal direction can be achieved between the hanging member 832 and the fixing base 831. Thus, by adjusting the relative position between the hanging member 832 and the fixing base 831, the position deviation between the cabinet door 2 and the box door 1 can be adjusted, enabling the box door 1 and the cabinet door 2 to correct slight deviations in installation or manufacturing through fine-tuning, ensuring the aesthetic appearance of the installation of the box door 1 and the cabinet door 2.

[0114] Specifically, the fixing base 831 is connected to the cabinet door 2 to provide additional structural support for the cabinet door 2. An installation groove is formed on the fixing base 831 for accommodating the hanging member 832; the hanging member 832 is slidably arranged in the installation groove, and a first clamping joint 8321 is formed on the hanging member 832 to adjust the relative position between the cabinet door 2 and the box door 1 by adjusting the position of the hanging member 832 in the installation groove. Through the adjustable design, the user can adjust the position of the cabinet door 2 according to actual needs to meet the requirements of different usage scenarios.

[0115] Specifically, the first clamping joint 8321 is a downward U-shaped hook that can slide through the notch into the first clamping groove 8221. A first rectangular hole extending in the up-down direction is provided on the hanging member 832. The fixing base 831 is provided with two installation holes and an installation groove extending left and right between the two installation holes. A second rectangular hole extending in the left-right direction is provided on the side wall of the installation groove. The hanging member 832 can slide in the installation groove. By controlling the position of the hanging member 832 in the installation groove, the hanging member 832 can move up and down relative to the fixing base 831. Screws can be set to pass through the first rectangular hole on the installation groove and the second rectangular hole on the hanging member 832, forming a hanging member 832 that can be adjusted in both the up-down and left-right directions. And through the relative position between the installation holes of the fixing base 831 and the cabinet door 2, the position of the fixing base 831 and the cabinet door 2 can be adjusted in the up-down, left-right directions.

[0116] As Figure 7 and Figure 8 shown, the process of installing the hanging part 83 on the cabinet door 2 is as follows:

[0117] Thread the pendant 832 through the installation groove of the fixing base 831. Use screws to pass through the second rectangular hole, the first rectangular hole, and the cabinet door 2 to integrally connect the fixing base 831 to the cabinet door 2. Hang the first card joint 8321 on the pendant 832 that is connected well in the first card slot 8221 to complete the connection between the pendant 832 and the adapter base 822. Then, by observing the positional relationship between the cabinet door 2 and the box door 1, check whether there is any deviation. If there is a deviation, the position can be adjusted through the first rectangular hole and the second rectangular hole. When the deviation is large, the screws can be removed to separate the hanging part 83 from the cabinet door 2 and adjust the position of the hanging part 83. Adjust the position of the pendant 832 for the cabinet door 2 and the fixing base 831, and the pendant 832 assembly. If the positional relationship meets the requirements and no adjustment is needed, use screws to pass through the installation holes on both sides of the fixing base 831 and the cabinet door 2 to further fix the cabinet door 2 and the fixing base 831 to keep its position stable. Through the above method, not only can the position of the fixing base 831 be finely adjusted, but also it can be ensured that all fixings are firm, guaranteeing the accurate positional relationship between the cabinet door 2 and the box door 1.

[0118] In a second aspect, as Figure 2 shown, an embodiment of the present invention further provides a door assembly, including: a box door 1, a cabinet door 2, and a sliding door mechanism. The box door 1 is rotatably arranged on the cabinet of the refrigeration device 9 to open or close the storage compartment inside the cabinet 9. The cabinet door 2 is arranged on the side of the box door 1 facing away from the cabinet 9 and is movably arranged on the box door 1 along the width direction. The sliding door mechanism is the sliding door mechanism as described above.

[0119] 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.

[0120] Specifically, since the door assembly includes a sliding door mechanism, and the specific structure of the sliding door mechanism refers to the above embodiment, the door assembly 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 one by one here.

[0121] It can be understood that the door assembly in the present invention can be applied to household appliances, such as a refrigerator. During the opening or closing process of the box door 1, the sliding door mechanism drives the cabinet door 2 to move relative to the box door 1.

[0122] For the door body assembly shown in this embodiment, by rotatably connecting the cabinet door 1 to the cabinet body 9, arranging the door 2 movably along the width direction of the cabinet door 1 outside the cabinet door 1, and using a sliding door mechanism to connect the cabinet door 1 and the door 2, during the opening or closing process of the sliding door mechanism, the movement of the door 2 relative to the cabinet door 1 is controlled, so that the cabinet door 1 can avoid the side cabinet body during the opening and closing processes, thereby avoiding the interference between the door 2 and the outside when the cabinet door 1 rotates, and meeting the usage requirements of users in different scenarios.

[0123] Specifically, during the movement of the door 2 relative to the cabinet door 1, the door 2 can move left and right relative to the cabinet door 1 along the width direction.

[0124] Such a design not only improves the convenience of use but also can avoid possible damage to the door body assembly during use. At the same time, this design also enables the refrigeration equipment to better integrate into the home environment, achieving the effects of overall beauty and sealing.

[0125] In a third aspect, as Figure 2 and Figure 9 shown, the embodiment of the present invention further provides a refrigeration equipment, including: a cabinet body 9 and the door body assembly as above. The cabinet body 9 has a storage compartment, and the cabinet door 1 is rotatably arranged on the cabinet body 9 to open or close the storage compartment.

[0126] Specifically, since the refrigeration equipment includes a door body assembly, and the specific structure of the door body assembly refers to the above embodiment, the refrigeration equipment 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 here one by one.

[0127] It can be understood that the cabinet door 1 is used to open and close the storage compartment. When the refrigeration equipment is fully embedded, in order to keep the consistency between the refrigeration equipment and the surrounding cabinet bodies, the door 2 with the same material and color as the surrounding cabinet bodies is installed outside the cabinet door 1.

[0128] The refrigeration equipment of this embodiment can install the door 2 on the cabinet door 1 through a sliding door mechanism, so that during the opening and closing of the refrigeration equipment, the interference between the door 2 and the cabinet bodies around the refrigeration equipment can be avoided, greatly improving the convenience of use. Especially in a limited kitchen environment, this design advantage is more obvious. In addition, the setting of the sliding door mechanism enables the door 2 to move smoothly during the opening and closing processes, improving the service life and stability of the refrigerator.

[0129] In some embodiments, as Figure 2 shown, the cabinet body 9 is configured to be arranged in the accommodation space between the first cabinet body 11 and the second cabinet body 12.

[0130] During the opening or closing process of the cabinet door 1, the driving member 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 11 or the second cabinet body 12.

[0131] It can be understood that an opening is provided on the outer side of the accommodating space between the first cabinet body 11 and the second cabinet body 12. 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 accommodating space, the driving member is configured to drive the cabinet door 2 on the cabinet door 1 to move a preset distance in a direction away from or towards the cabinet body 9 so that the cabinet door 2 avoids the side walls of the first cabinet body 11 and the second cabinet body 12.

[0132] During the process of the cabinet door 1 passing through the opening to control the opening or closing of the accommodating space, the driving member is configured to drive the cabinet door 2 on the cabinet door 1 to move in a direction away from or towards the cabinet body 9. This design is mainly to avoid interference between the cabinet door 2 and the side walls of the first cabinet body 11 and the second cabinet body 12. Through the movement of the cabinet door 2, 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 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 beauty and sealing.

[0133] In some embodiments, as Figure 2 shown, the cabinet door 1 is rotatably connected to the cabinet body 9 through a hinge 10; the cabinet door 2 can move relative to the cabinet door 1 between a first position and a second position in the width direction.

[0134] 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 facing the hinge 10 is arranged close to the hinge 10.

[0135] 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 facing the hinge 10 is arranged away from the hinge 10 to avoid the side walls of the first cabinet body 11 or the second cabinet body 12.

[0136] 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 a closed state, and the side of the cabinet door 2 is at a first distance (close to zero) relative to the hinge 10 of the refrigeration device. 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 block the cabinet door 1, ensuring that the door body of the refrigeration device exposed from the accommodating space is consistent with the surrounding first cabinet body 11 and second cabinet body 12 in appearance.

[0137] When the cabinet door 1 opens the storage compartment, the cabinet door 1 is in an open state. 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 10 of the refrigeration device. For example, the side wall of the cabinet door 2 and the side wall of the cabinet door 1 are misaligned, and a gap is formed that can accommodate the side of the first cabinet body 11 or the second cabinet body 12, so as to prevent the cabinet door 2 from colliding with or interfering with the first cabinet body 11 or the second cabinet body 12 due to the opening of the cabinet door 1.

[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.
