In addition, those skilled in the art can combine and combine different embodiments or examples described in this specification and the features of different embodiments or examples, unless they are contradictory.

[0072] The door assembly and refrigeration device of the present application are described below with reference to Figures 1 to 12. The door assembly of the present application can be applied to household appliances, such as refrigerators, but it should be understood that the door assembly of the present application can also be applied to dishwashers, washing machines, or any other suitable equipment.

[0073] In one embodiment of the present application, as shown in Figures 1 to 3, the door assembly includes: a cabinet door 2, a door panel 3, and a transmission mechanism 5. The cabinet door 2 is rotatably connected to the appliance body 1 via a hinge 4, and the cabinet door 2 is suitable for opening or closing the storage space of the appliance body 1. The door panel 3 is slidably disposed on the outside of the cabinet door 2, and the transmission mechanism 5 drives the door panel 3 to move relative to the cabinet door 2 during the process of opening or closing the cabinet door 2.

[0074] The transmission mechanism 5 may include transmission components such as connecting rods, gears, and racks, which are connected to the door 2 and the door panel 3 by appropriate connection methods (such as bolt connection, welding, etc.). In this way, when the door 2 rotates, the transmission mechanism 5 can drive the door panel 3 to move along the door 2.

[0075] Specifically, as shown in Figure 1, when the door 2 is opening, the transmission mechanism 5 drives the door panel 3 to move away from the hinge 4 (moving to the left relative to the door 2), thereby preventing the door panel 3 from interfering with objects on the side. When the door 2 is closing, the transmission mechanism 5 drives the door panel 3 to move toward the hinge 4 (moving to the right relative to the door 2), thereby ensuring that the door panel 3 can avoid objects on the side when closing.

[0076] According to the door assembly of the embodiment of the present application, the cabinet door 2 is rotatably connected to the appliance body 1, and the door panel 3 is slidably arranged on the outside of the cabinet door 2, and the cabinet door 2 and the door panel 3 are connected by a transmission mechanism 5. During the opening or closing process of the transmission mechanism 5, the door panel 3 is controlled to move relative to the cabinet door 2, so that the cabinet door 2 can be staggered with the side cabinet body during the opening and closing process, which can avoid interference between the door panel 3 and the outside when the cabinet door 2 rotates, and can meet the user's usage needs in different scenarios.

[0077] During the movement of the door panel 3 relative to the box door 2 , the door panel 3 may move left and right relative to the box door 2 , or the door panel 3 may move up and down relative to the box door 2 .

[0078] The movement relationship between the door panel 3 and the door 2 needs to be explained in detail. There are two main ways for the door panel 3 to move relative to the door 2: one is that the door panel 3 can move left and right relative to the door 2; the other is that the door panel 3 can move up and down relative to the door 2.

[0079] When the door panel 3 moves left or right relative to the door 2, the door panel 3 remains unchanged in the vertical direction relative to the door 2, while moving in the horizontal direction. This means that the position of the door panel 3 changes as it moves left or right relative to the door 2, while the vertical distance between the door panel 3 and the door 2 remains unchanged.

[0080] When the door panel 3 moves up and down relative to the door 2, the door panel 3 remains unchanged in the horizontal direction of the door 2, while moving in the vertical direction. This means that the position of the door panel 3 changes as it moves up and down relative to the door 2, while the horizontal distance between the door panel 3 and the door 2 remains unchanged.

[0081] When the door panel 3 moves left or right (or up or down) relative to the door 2, this does not mean that the only way for the door panel 3 to move is left or right (or up or down) relative to the door 2. In fact, within a certain tolerance range, the door panel 3 can move in a variety of ways. For example, the door panel 3 can move horizontally or vertically relative to the door 2 within a tolerance range of ±5°.

[0082] Furthermore, we must clarify the relationship between the door panel 3 and the door 2. This connection is not limited to simple left-right (or up-and-down) movement, but also includes various other possible relative motions. These motions may include slight vibrations and swings, which go beyond simple left-right (or up-and-down) movement.

[0083] In actual operation, the movement of the door panel 3 cannot be carried out completely accurately in accordance with the predetermined direction and distance, and there will always be a certain error. Therefore, as long as this error is within an acceptable range, the movement of the door panel 3 can be regarded as an effective movement.

[0084] In addition, the movement of the door panel 3 may also be affected by external factors, such as wind, vibration, etc. These factors may cause the door panel 3 to make corresponding adjustments within a certain range to maintain its relative position with the door 2.

[0085] In the embodiment of the present application, as shown in Figures 1 to 3, the door assembly and the appliance body 1 are intended to be disposed within an installation space 100 formed between a first cabinet 11 and a second cabinet 12. An opening is provided on the outside of the installation space 100. This design allows the door assembly and the appliance body 1 to be integrally embedded within the cabinet. When the door 2 passes through the opening to control the opening or closing of the storage space, the transmission mechanism 5 is configured to drive the door panel 3 on the door 2 to move a predetermined distance away from or toward the hinge 4, so that the door panel 3 avoids the side walls of the first cabinet 11 and the second cabinet 12.

[0086] As door 2 passes through the opening to open or close the storage space, transmission mechanism 5 is configured to drive door panel 3 on door 2 a predetermined distance, moving away from or toward hinge 4. This design prevents door panel 3 from interfering with the sidewalls of first and second cabinets 11, 12. By moving the predetermined distance, door panel 3 can be opened or closed smoothly without colliding or getting stuck with the cabinet sidewalls.

[0087] For example, as shown in Figures 1 and 2, during the opening process of the door 2, the transmission mechanism 5 drives the door panel 3 to move a predetermined distance along the door 2 away from the hinge 4 (relative to the predetermined distance to the left of the door 2). In this way, the door panel 3 can smoothly avoid the side wall of the second cabinet 12, allowing the door 2 to be fully opened, making it convenient for the user to store and retrieve items.

[0088] Similarly, when the door 2 is closing, the transmission mechanism 5 drives the door panel 3 to move a predetermined distance along the door 2 toward the hinge 4 (relative to the predetermined distance that the door 2 moves to the right). In this way, the door panel 3 can smoothly avoid the side wall of the first cabinet 11, allowing the door 2 to be completely closed, maintaining the overall aesthetics and sealing.

[0089] This design not only improves the convenience of use, but also avoids possible damage to the door assembly during use. At the same time, this design also allows the appliance to better integrate into the home environment, improving the overall aesthetics of the home.

[0090] In another embodiment, as shown in Figure 4, the door assembly and the electrical appliance body 1 are used to be set in a cabinet 13; during the process of opening or closing the cabinet door 3, the transmission mechanism 5 is configured to drive the door panel 3 to move a preset distance on the cabinet door 2 so that the door panel 3 avoids the side wall of the cabinet 13.

[0091] Specifically, during the opening process of the door 2, the transmission mechanism 5 drives the door panel 3 to move a predetermined distance along the door 2 away from the hinge 4 (relative to the predetermined distance that the door 2 moves to the left). In this way, the door panel 3 can smoothly avoid the right side wall of the cabinet body 13, allowing the door 2 to be fully opened, making it convenient for the user to store and retrieve items.

[0092] Similarly, when the door 2 is closing, the transmission mechanism 5 drives the door panel 3 to move a predetermined distance along the door 2 toward the hinge 4 (relative to the predetermined distance the door 2 moves to the right). In this way, the door panel 3 can smoothly avoid the side wall on the left side of the cabinet body 13, allowing the door 2 to be completely closed, maintaining the overall aesthetics and sealing.

[0093] In one embodiment of the present application, as shown in Figures 3 to 6 , the transmission mechanism 5 includes a driving member 51, a driven member 52, and a transmission member 53. The driving member 51 is in transmission connection with the door 2, and the driven member 52 is connected to the door panel 3. The driving member 51 is in transmission connection with the driven member 52 via the transmission member 53, so that when the door 2 drives the driving member 51, the door panel 3 is driven by the driven member 52 to move along the door 2 toward or away from the hinge 4.

[0094] In this embodiment, the driving member 51 is in transmission connection with the door 2, which is usually achieved by rotation or sliding, so that when the door 2 is opened or closed, the driving member 51 can rotate or move accordingly. This connection method can be a gear and rack meshing, a pulley and rope connection, etc. The specific selection depends on design requirements and available technical conditions.

[0095] The follower 52 is connected to the door panel 3 so that the door panel 3 can move with the rotation or movement of the driving member 51. This connection method can be a connection between a pulley and a rope, a connection between a shaft and a connecting rod, etc. The specific selection depends on design requirements and available technical conditions.

[0096] The driving member 51 is connected to the driven member 52 via a transmission member 53. The transmission member 53 transmits force, so that when the driving member 51 rotates or moves, it drives the driven member 52 to rotate or move. This transmission connection can be a chain, gear, connecting rod, rack, or other interconnected components, the specific choice of which depends on design requirements and available technical conditions.

[0097] When the door 2 is opened or closed, the driver 51 drives the follower 52 to move along the door 2 toward or away from the hinge 4 (left and right movement relative to the door 2). During this process, the door panel 3 moves with the follower 52, avoiding interference with the cabinet sidewalls and achieving smooth movement and reliable control of the refrigerator door.

[0098] In a specific embodiment, as shown in Figures 3 to 6, the transmission mechanism 5 further includes: a transmission base 54. The transmission base 54 is arranged on the box door 2 to provide stable support and guidance. A first guide rail 541 is formed on one side of the transmission base 54, and a second guide rail 542 is formed on the other side of the transmission base 54. The first guide rail 541 and the second guide rail 542 on the transmission base 54 are arranged in parallel. The driving member 51 is slidably arranged on the first guide rail 541, and the driven member 52 is slidably arranged on the second guide rail 542, so as to provide a stable guiding effect through the first guide rail 541 and the second guide rail 542.

[0099] Among them, the transmission member 53 includes a first connecting member 531 and a second connecting member 532. The first connecting member 531 bypasses one end of the transmission base 54, and the two ends of the first connecting member 531 are respectively connected to one end of the driving member 51 and the driven member 52; the second connecting member 532 bypasses the other end of the transmission base 54, and the two ends of the second connecting member 532 are respectively connected to the other end of the driving member 51 and the driven member 52.

[0100] During operation, the transmission mechanism 5 achieves stable and reliable transmission. When the door 2 is opened or closed, the driver 51 slides on the first guide rail 541 and, through the connection between the first connecting member 531 and the second connecting member 532, drives the follower 52 to slide on the second guide rail 542. This design precisely controls the movement trajectory and distance of the door panel 3, avoiding interference with the cabinet sidewalls and ensuring smooth opening and closing of the door 2.

[0101] Specifically, during the process of opening and closing the door, the change in the angle of the door 2 drives the driving member 51 to move on the first guide rail 541. The connection between the first connecting member 531 and the second connecting member 532 drives the follower 52 to move in the opposite direction on the second guide rail 542. Since the follower 52 is connected to the door panel 3, the door panel 3 can move on the door 2, thereby allowing the door panel 3 to avoid the cabinet body on the side.

[0102] It should be noted that a first mounting groove 21 is provided on one edge of the door 2, and a plurality of screw holes are provided in the first mounting groove 21. A first fixing block 543 and a second fixing block 544 are provided at both ends of the transmission base 54. The first and second fixing blocks 543 and 544 have through-holes corresponding to the screw holes in the first mounting groove 21. Thus, bolts can be provided on the first and second fixing blocks 543 and 544 to secure the transmission base 54 to the first mounting groove 21.

[0103] In one embodiment, as shown in Figures 3 to 6, two first guide rails 541 are formed on one side of the transmission base 54, positioned vertically opposite each other. The driver 51 is slidably disposed between the two first guide rails 541. This further enhances the guiding effect on the driver 51, allowing the driver 51 to move more stably along the guide rails. The provision of the two first guide rails 541 improves the overall stability and reliability of the transmission mechanism 5, facilitating precise control and smooth movement.

[0104] Similarly, the other side of the transmission base 54 can also be formed with two second guide rails 542 arranged in an upper and lower position, with the follower 52 slidably disposed between the two second guide rails 542. This enhances the guidance of the follower 52, allowing it to move more stably along the guide rails. The provision of two second guide rails 542 improves the stability and reliability of the follower 52, further optimizing the movement trajectory and distance control of the door panel 3. This design, by increasing the number of guide rails, improves the overall rigidity and stability of the transmission mechanism 5, allowing the door assembly to open and close more smoothly and stably.

[0105] In some embodiments, as shown in Figures 3 to 6, the driving member 51 includes a connecting rod 512 and a first slider 511. One end of the connecting rod 512 is rotatably connected to the hinge 4 or hinged to the appliance body 1, and the other end of the connecting rod 512 is rotatably connected to the first slider 511. The first slider 511 is slidably disposed on the first guide rail 541.

[0106] In this embodiment, one end of the connecting rod 512 is hingedly connected to the fixing seat 514 via a first pin 513. The other end of the connecting rod 512 is hingedly connected to the mounting plate 518 on the first slider 511 via a second pin 515. The fixing seat 514 is fixed to the screw hole on the hinge 4 via a screw. When the door 2 rotates, the connecting rod 512 rotates accordingly, driving the first slider 511 to move on the first guide rail 541. The connection between the first connecting member 531 and the second connecting member 532 drives the follower 52 to move in the opposite direction on the second guide rail 542. Because the follower 52 is connected to the door panel 3, the door panel 3 can move on the door 2. The sliding connection between the first slider 511 and the first guide rail 541 ensures stable movement of the driver 51.

[0107] Accordingly, the follower 52 includes a second slider 521. The second slider 521 is slidably mounted on a second guide rail 542 and connected to the door panel 3. Driven by the first and second connecting members 531 and 532, the second slider 521 can move on the second guide rail 542, thereby driving the door panel 3 to move. The sliding connection between the second slider 521 and the second guide rail 542 ensures stable movement of the follower 52.

[0108] Furthermore, considering the needs of practical applications, a limiting structure can be provided at the ends of the first guide rail 541 and the second guide rail 542. The limiting structure allows the first slider 511 and the second slider 521 to move within a set range of movement, thereby adjusting the movement distance as needed to meet the requirements of different applications.

[0109] In practical applications, the positioning structure allows the first and second sliders 511, 521 to move within a set range of motion. This design fully satisfies the requirements for the desired travel distance. The first and second sliders 511, 521 can reach predetermined positions during movement and stop at their limit positions, avoiding damage or safety hazards caused by excessive movement. Furthermore, this positioning structure facilitates control of the first and second sliders 511, 521. By setting different limit points, precise control of the slider movement can be achieved, thereby precisely controlling the travel distance of the door panel 3 to meet the needs of various application scenarios.

[0110] In one embodiment, as shown in Figures 5 and 6, a positioning member 516 and a limiting member 517 corresponding to the positioning member 516 are formed on the driving member 51 and / or the driven member 52, and the first connecting member 531 and / or the second connecting member 532 pass through the limiting member 517 to be connected to the positioning member 516.

[0111] In a specific embodiment, the positioning member 516 can be a column, which is vertically arranged on the first slider 511 and the second slider 521, while the limiting member 517 can be an arched rib. The first slider 511 of the driving member 51 is provided with two columns and arched ribs corresponding to the columns on both sides. The second slider 521 of the driven member 52 is provided with two columns and arched ribs corresponding to the columns on both sides. One end of the first connecting member 531 passes through the first slider 511, and one of the arched ribs is wrapped around the corresponding column. The other end of the first connecting member 531 passes through the second slider 521, and one of the arched ribs is wrapped around the corresponding column. One end of the second connecting member 532 passes through another arched rib of the first slider 511 and is wrapped around the corresponding column. The other end of the second connecting member 532 passes through another arched rib of the second slider 521 and is wrapped around the corresponding column. Through the cooperation of the first connecting member 531, the second connecting member 532, the column and the arched rib, not only the connection between the first slider 511 and the second slider 521 is achieved, but also the limitation of the arched rib can facilitate the transmission of power between the first slider 511 and the second slider 521.

[0112] In one example, as shown in Figures 3 and 7, the door panel assembly further includes a connecting mechanism 8, which is connected to the door panel 3. The connecting mechanism 8 can be an independent component or a part of the door panel 3. One of the second slider 521 and the connecting mechanism 8 is formed with a first card slot 522, and the other is formed with a first card joint 81 adapted to the first card slot 522. The second slider 521 is detachably connected to the connecting mechanism 8 via the first card joint 81 and the first card slot 522.

[0113] In this embodiment, a first card slot 522 is provided on the second slider 521, a notch is provided on one side of the first card slot 522, and a first card joint 81 is provided on the connecting mechanism 8. The first card joint 81 can pass through the notch and be fixed in the first card slot 522. Since the connecting mechanism 8 is connected to the door panel 3, the connection between the second slider 521 and the door panel 3 can be achieved through the connection between the first card joint 81 and the first card slot 522.

[0114] This detachable connection makes the connection between the second slider 521 and the connecting mechanism 8 more flexible and convenient. Whether or not to install the connecting mechanism 8 can be determined based on actual needs, as can the appropriate connection method for different usage scenarios. This design improves the versatility and adaptability of the door panel assembly, while simplifying the manufacturing and assembly process and reducing production and maintenance costs.

[0115] In another embodiment, as shown in Figures 3 and 7, a first card slot 522 is formed on the second slider 521. The connecting mechanism 8 includes a fixed plate 83 and a connecting block 82. The fixed plate 83 is connected to the door panel 3 to provide additional structural support for the door panel 3. The fixed plate 83 is formed with a mounting groove for accommodating the connecting block 82; the connecting block 82 is slidably disposed in the mounting groove, and a first card joint 81 is formed on the connecting block 82 to adjust the relative position of the door panel 3 and the cabinet door 2 by adjusting the position of the connecting block 82 in the mounting groove. Through this adjustable design, the user can adjust the position of the door panel 3 according to actual needs to meet the needs of different usage scenarios.

[0116] Specifically, the first clamping joint 81 is a U-shaped hook facing downward that can be slid through the notch into the first clamping slot 522. The connecting block 82 is provided with a first rectangular hole extending in the vertical direction. The fixing plate 83 is provided with two mounting holes and a mounting slot extending left and right between the two mounting holes. The sidewalls of the mounting slot are provided with a second rectangular hole extending left and right. The connecting block 82 can slide in the mounting slot. By controlling the position of the connecting block 82 in the mounting slot, the connecting block 82 can be moved up and down relative to the fixing plate 83. Screws can be provided through the first rectangular hole in the mounting slot and the second rectangular hole in the connecting block 82 to form a connecting block 82 that is adjustable in both the vertical and horizontal directions. The relative position of the mounting holes in the fixing plate 83 and the door panel 3 allows the position of the fixing plate 83 and the door panel 3 to be adjusted in the vertical and horizontal directions.

[0117] As shown in FIG7 and FIG8, the process of installing the connecting mechanism 8 adapted to the transmission mechanism 5 and the door panel 3 is as follows:

[0118] Insert the connecting block 82 into the mounting slot of the fixing plate 83. Use screws inserted through the second rectangular hole, the first rectangular hole, and the door panel 3 to connect the connecting mechanism 8 to the door panel 3. Hang the first clamping joint 81 on the connected connecting block 82 into the first clamping slot 522 to complete the connection between the connecting block 82 and the second slider 521. Then, observe the positional relationship between the door panel 3 and the door 2 to detect any deviation. If there is deviation, adjust the position using the first and second rectangular holes. If the deviation is large, remove the screws, separate the connecting mechanism 8 from the door panel 3, and adjust the position of the connecting mechanism 8. Assemble the door panel 3, the fixing plate, and the connecting block to adjust the position of the connecting block 82. If the positional relationship meets the requirements and no adjustment is required, use screws inserted through the mounting holes on both sides of the fixing plate 83 and the door panel 3 to further secure the door panel 3 to the fixing plate 83 to maintain their stable position. This method not only allows for fine-tuning the position of the connecting mechanism 8, but also ensures that all fixations are secure and ensures the accurate positional relationship between the door panel 3 and the door 2.

[0119] In one embodiment, as shown in Figures 3 and 9, the door body assembly also includes: a guide mechanism 6; the guide mechanism 6 includes a guide base 62 and a third slider 61, the guide base 62 is arranged on the box door 2, and a third guide rail 621 is formed on the guide base 62, the third slider 61 is slidably arranged on the third guide rail 621, and the third slider 61 is connected to the door panel 3.

[0120] The third slider 61 is connected to the door panel 3 in a manner that can be selected according to actual needs, such as by screws, welding, snap fasteners, etc. With this connection method, when the door panel 3 and the door 2 slide relative to each other, the door panel 3 can push the third slider 61 to slide on the third guide rail 621, which can significantly increase the stability of the door panel 3 and the door 2 during the relative sliding process.

[0121] In addition, by designing the third guide rail 621, for example, providing a limiting structure at the end of the third guide rail 621, the moving distance of the door panel 3 can be adjusted according to actual needs to meet the needs of different users.

[0122] The box door 2 is provided with a first mounting groove 21 adapted to the transmission mechanism 5, and the transmission mechanism 5 is installed in the first mounting groove 21; and / or, the box door 2 is provided with a second mounting groove 22 adapted to the guide mechanism 6, and the guide mechanism 6 is installed in the second mounting groove 22.

[0123] Inside the door 2, a first mounting groove 21 is provided that matches the transmission mechanism 5, allowing the transmission mechanism 5 to be smoothly installed in the first mounting groove 21. This design ensures that the door 2 and the transmission mechanism 5 form a stable fit during opening and closing, reducing the overall thickness of the door 2 and door panel 3.

[0124] Furthermore, door 2 is provided with a second mounting slot 22 adapted to accommodate guide mechanism 6. Guide mechanism 6 provides stable guidance during the movement of door 2, preventing it from wobbling or straying from its path during opening and closing. By installing guide mechanism 6 in second mounting slot 22, the stability and accuracy of door 2 during movement are ensured, while also reducing the overall thickness of door 2 and door panel 3.

[0125] Typically, two third guide rails 621 are formed on one side of the guide base 62, positioned vertically opposite each other. The third slider 61 is slidably disposed between the two third guide rails 621. This enhances the guidance of the third slider 61, allowing it to move more stably along the guide rails. The provision of two third guide rails 621 improves overall stability and reliability during guidance, facilitating precise control and smooth movement.

[0126] In order to cooperate with the fixation of the guide mechanism 6, a plurality of connecting mechanisms 8 are provided, and the third slider 61 and one of the connecting mechanisms 8 form a second card slot 611, and the other forms a second card joint adapted to the second card slot 611. The third slider 61 is detachably connected to the connecting mechanism 8 through the second card joint and the second card slot 611.

[0127] In this embodiment, a second card slot 611 is provided on the third slider 61, a notch is provided on one side of the second card slot 611, and a second card joint is provided on the connecting mechanism 8. The second card joint can pass through the notch and be fixed in the second card slot 611. Since the connecting mechanism 8 is connected to the door panel 3, the connection between the third slider 61 and the door panel 3 can be realized through the connection between the second card joint and the second card slot 611.

[0128] This detachable connection makes the connection between the third slider 61 and the connecting mechanism 8 more flexible and convenient. Whether or not to install the connecting mechanism 8 can be determined based on actual needs, as can the appropriate connection method for different usage scenarios. This design improves the versatility and adaptability of the door panel assembly, while simplifying the manufacturing and assembly process and reducing production and maintenance costs.

[0129] In this embodiment, the first card joint 81 has the same structure as the second card joint, that is, the connecting mechanism 8 for connecting the second slider 521 has the same structure as the connecting mechanism for connecting the third slider 61. As shown in Figure 7, the connecting mechanism 8 includes: a fixed plate 83 and a connecting block 82. The fixed plate 83 is connected to the door panel 3 to provide additional structural support for the door panel 3. A mounting groove is formed on the fixed plate 83 to accommodate the connecting block 82; the connecting block 82 is slidably set in the mounting groove, and a first card joint 81 is formed on the connecting block 82 to adjust the relative position of the door panel 3 and the cabinet door 2 by adjusting the position of the connecting block 82 in the mounting groove. Through this adjustable design, the user can adjust the position of the door panel 3 according to actual needs to meet the needs of different usage scenarios.

[0130] Specifically, the second snap connector is a U-shaped hook facing downward that can slide through the notch into the second snap slot 611. The connecting block 82 is provided with a first rectangular hole extending in the vertical direction. The fixing plate 83 is provided with two mounting holes and a mounting slot extending left and right between the two mounting holes. The sidewalls of the mounting slot are provided with a second rectangular hole extending left and right. The connecting block 82 can slide in the mounting slot. By controlling the position of the connecting block 82 in the mounting slot, the connecting block 82 can be moved up and down relative to the fixing plate 83. Screws can be provided through the first rectangular hole in the mounting slot and the second rectangular hole in the connecting block 82 to form a connecting block 82 that is adjustable in both the vertical and horizontal directions. The relative position of the mounting holes in the fixing plate 83 and the door panel 3 allows the position of the fixing plate 83 and the door panel 3 to be adjusted in the vertical and horizontal directions.

[0131] As shown in FIG7 to FIG9, the process of installing the connecting mechanism 8 adapted to the guide mechanism 6 and the door panel 3 is as follows:

[0132] Insert the connecting block 82 into the mounting groove of the fixing plate 83. Use screws to pass through the second rectangular hole, the first rectangular hole and the door panel 3 to connect the connecting mechanism 8 as a whole to the door panel 3. Hang the second card connector on the connected connecting block 82 in the second card slot 611 to complete the connection between the connecting block 82 and the third slider 61. Then detect whether there is a deviation by observing the positional relationship between the door panel 3 and the box door 2. 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 connecting mechanism 8 from the door panel 3 and adjust the position of the connecting mechanism 8. The door panel 3 and the fixing plate, the connecting block assembly, adjust the position of the connecting block 82. If the positional relationship meets the requirements and does not need to be adjusted, use screws to pass through the mounting holes on both sides of the fixing plate 83 and the door panel 3 to further fix the door panel 3 to the fixing plate 83 to keep its position stable.

[0133] In some embodiments, as shown in FIG3 , multiple guide mechanisms 6 are provided. For guidance, the third guide rail 621 in each guide mechanism 6 is arranged parallel to the first guide rail 541 and the second guide rail 542 on the transmission mechanism 5 . This parallel arrangement ensures that the door panel 3 is accurately guided during movement, avoiding interference with the cabinet sidewalls. This coordination between the guide mechanism 6 and the transmission mechanism 5 enables smooth and stable movement of the door panel 3, improving ease of use and reliability.

[0134] This design can be adjusted and optimized according to actual needs, such as changing the number, position, and size of the guide mechanisms 6, and adjusting the parallelism of the third guide rail 621 with the first guide rail 541 and the second guide rail 542. These adjustments can be made according to specific usage scenarios to achieve optimal performance and user experience.

[0135] Specifically, as shown in Figures 3 and 9 to 11, in this embodiment, the box door 2 is provided with a first mounting groove 21 and three second mounting grooves 22. The first mounting groove 21 is arranged at the top of the right side of the box door 2, one of the second mounting grooves 22 is correspondingly arranged at the top of the left side of the box door 2, and the other two second mounting grooves 22 are respectively arranged on the left and right sides of the bottom of the box door 2. The corresponding door body assembly is provided with a transmission mechanism 5 and three guide mechanisms 6. The transmission mechanism 5 is installed in the first mounting groove 21, and the other three guide mechanisms 6 are respectively arranged in the three second mounting grooves 22. One of the three guide mechanisms 6 is a top guide mechanism, as shown in Figure 9. The other two guide mechanisms 6 are bottom guide mechanisms, as shown in Figure 10. The top guide mechanism 6 has the same structure as the bottom guide mechanism 6, and the two are symmetrically arranged.

[0136] As shown in Figures 8 and 12, there are four connecting mechanisms 8, each corresponding to one transmission mechanism 5 and three guide mechanisms 6. The connection process is to first fix the connecting mechanism 8 to the door panel 3 through the first rectangular hole and the second rectangular hole, connect the connecting mechanism 8 to the corresponding slider, and finally adjust the door 2 and the door panel 3 to ensure that there is no problem. Then, screws are used to pass through the mounting holes on both sides of the fixing plate 83 and the door panel 3 to further fix the door panel 3 to the fixing plate 83. The specific process can be referred to the above embodiment and will not be repeated here.

[0137] As shown in Figures 1 and 2, when the door 2 is opened, the transmission mechanism 5 drives the door panel 3 to move a preset distance along the door 2 in the direction away from the hinge 4. During this process, the door panel 3 moves outward under the constraints of the three guide mechanisms 6. In this way, the door panel 3 can smoothly avoid the side walls of the second cabinet 12 and ensure stability during movement, allowing the door 2 to be fully opened, making it convenient for users to store and access items. Similarly, when the door 2 is closed, the transmission mechanism 5 drives the door panel 3 to move a preset distance along the door 2 in the direction toward the hinge 4. During this process, the door panel 3 moves inward under the constraints of the three guide mechanisms 6. In this way, the door panel 3 can smoothly avoid the side walls of the first cabinet 11, allowing the door 2 to be fully closed, maintaining its overall aesthetics and sealing.

[0138] In some embodiments, as shown in Figures 13 and 14 , the transmission mechanism 5 further includes a first rotating shaft 57 and a second rotating shaft 58. The transmission member 53 includes a transmission belt, which is sleeved on the first rotating shaft 57 and the second rotating shaft 58. The transmission belt includes an upper side belt 533 located on one side of the first rotating shaft 57 and the second rotating shaft 58, and a lower side belt 534 located on the other side of the first rotating shaft 57 and the second rotating shaft. The driving member 51 is disposed on the upper side belt 533, and the driven member 52 is disposed on the lower side belt 534.

[0139] In this embodiment, the first and second rotating shafts 57 and 58 are used for support and transmission, ensuring stable movement of the driver 51, the driven member 52, and the transmission member 53. The transmission member 53 is in the form of a transmission belt, which offers high flexibility and can accommodate different motion paths and distance requirements. The transmission belt is mounted on the first and second rotating shafts 57 and 58, and the rotation of these two shafts achieves tension and movement of the transmission belt.

[0140] The driving member 51 is arranged on the upper side band 533. During the rotation of the box door 2, the driving member 51 drives the upper side band 533 to move along the first direction, and the lower side band 534 moves along the second direction under the traction of the upper side band 533. Since the follower 52 is arranged on the lower side band 534 and the follower 52 is connected to the door panel 3, the relative sliding between the door panel 3 and the box door 2 can be controlled under the traction of the lower side band 534.

[0141] Specifically, as shown in Figures 1 and 2, during the opening process of the door 2, the driver 51 drives the upper sideband 533 to move inward, while the lower sideband 534 drives the door panel 3 via the follower 52 to move a predetermined distance along the door 2 away from the hinge 4. In this way, the door panel 3 can smoothly avoid the side wall of the second cabinet body 12, allowing the door 2 to be fully opened, making it convenient for the user to store and retrieve items.

[0142] Similarly, when the door 2 is closing, the driver 51 drives the upper sideband 533 to move outward, and the lower sideband 534 drives the door panel 3 to move a predetermined distance along the door 2 toward the hinge 4 via the follower 52. In this way, the door panel 3 can smoothly avoid the side wall of the second cabinet body 12, allowing the door 2 to be completely closed.

[0143] In addition, by adjusting the positions and angles of the first rotating shaft 57 and the second rotating shaft 58, the movement trajectory and distance of the transmission belt can be adjusted according to actual needs to meet the needs of different users.

[0144] To change the travel of the driver 51 and the follower 52 to accommodate different user needs, the door assembly further includes a travel adjustment member. The travel adjustment member is configured to allow the travel of the driver 51 and the upper sideband 533 to differ from the travel of the follower 52 at the lower sideband 534.

[0145] The stroke adjustment member can be set as a pulley group or a movable pulley and other components as needed to change the stroke of the driving member 51 and the driven member 52. For example, the stroke of the driving member 51 can be reduced to increase the stroke of the driven member 52 to solve the interference problem caused by insufficient movement displacement of the small-angle door panel 3.

[0146] In this embodiment, to increase the displacement of door panel 3, the stroke adjustment member reduces the stroke between it and the upper sideband 533, so that the displacement of follower 52 on lower sideband 534 is twice that of driver 51, thereby increasing the displacement of door panel 3 on door 2. Furthermore, the design of the stroke adjustment member allows the movement trajectory of door panel 3 to be adjusted according to actual needs to meet the requirements of different users.

[0147] In one embodiment, as shown in Figures 15 to 18, the driving member 51 includes a first rack, the driven member 52 includes a second rack, and the transmission member 53 includes a transmission gear; the first rack is in transmission connection with the box door 2, the second rack is connected to the door panel 3, and the transmission gear is arranged between the first rack and the second rack, and the transmission gear is engaged with the first rack and the second rack, so that when the box door 2 drives the first rack to move, the second rack drives the door panel 3 to move in the opposite direction.

[0148] Specifically, in this embodiment, the first rack and the second rack are both mounted on a support frame 56. A first slideway for movement of the first rack and a second slideway for movement of the second rack are formed on the support frame 56. A transmission gear is disposed between the first rack and the second rack. The first rack is connected to the door 2 via a connecting rod. During rotation of the door 2, the first rack is pushed along the first slideway in a first direction. Reversing the direction of the transmission gear causes the second gear to move along the second slideway in a second direction. This allows the first rack and the second rack to move in different directions, thereby controlling the relative sliding between the door panel 3 and the door 2.

[0149] Specifically, as shown in Figures 1 and 2, when the door 2 is opened, the door 2 drives the first rack to move inward. When the transmission gear is switched, the second rack drives the door panel 3 to move a preset distance along the door 2 in a direction away from the hinge 4. In this way, the door panel 3 can smoothly avoid the side wall of the second cabinet body 12, allowing the door 2 to be fully opened, making it convenient for users to store and retrieve items.

[0150] Similarly, when the door 2 is closing, the door 2 drives the first rack to move outward, and when the transmission gear is switched, the second rack drives the door panel 3 to move a preset distance along the door 2 toward the hinge 4. In this way, the door panel 3 can smoothly avoid the side wall of the second cabinet body 12, allowing the door 2 to be completely closed.

[0151] As shown in Figures 16 and 17, in this embodiment, the door assembly further includes a guide mechanism 6. The guide mechanism 6 includes a guide base 62 and a third slider 61. The guide base 62 is disposed on the door 2. A third slide 622 is formed on the guide base 62. The third slider 61 is slidably disposed on the third slide 622. The third slider 61 is connected to the door panel 3. The third slider 61 is connected to the door panel 3 in a manner that can be selected according to actual needs, such as by screws, welding, or snap fasteners. With this connection method, when the door panel 3 slides relative to the door 2, the door panel 3 can push the third slider 61 to slide on the third slide 622, which can significantly increase the stability of the door panel 3 during the relative sliding process with the door 2.

[0152] In another embodiment of the present application, a refrigeration appliance is provided. The refrigeration appliance comprises a cabinet and a door assembly. The door assembly includes a door 2, a door panel 3, and a transmission mechanism 5. The cabinet defines a storage space. The door 2 is rotatably connected to the cabinet via a hinge 4, and is adapted to open or close the storage space. The door panel 3 is slidably disposed on the exterior side of the door 2. The transmission mechanism 5 drives the door panel 3 to move relative to the door 2 during the opening and closing process.

[0153] When the door 2 is opened, the transmission mechanism 5 drives the door panel 3 to move away from the hinge 4 (moving to the left relative to the door 2), thereby preventing the door panel 3 from interfering with objects on the side. When the door 2 is closed, the transmission mechanism 5 drives the door panel 3 to move toward the hinge 4 (moving to the right relative to the door 2), thereby ensuring that the door panel 3 can avoid objects on the side when closing.

[0154] The combination of door 2 and door panel 3 prevents interference between the door panel 3 and surrounding objects during opening and closing, significantly improving ease of use. This design advantage is particularly evident in cramped kitchen environments. Furthermore, the provision of transmission mechanism 5 ensures smooth movement of the door panel 3 during opening and closing, extending the lifespan and stability of the refrigerator.

[0155] The refrigeration device in the present application is applied as a refrigerator, for example, but it should be understood that the refrigeration device in the present application can also be applied as a freezer or any other suitable device, which is not limited here.

[0156] It can be understood that if the door assembly has the beneficial effects of the above embodiments, then the refrigeration equipment will correspondingly have the beneficial effects of the above embodiments. Its specific implementation can refer to the above embodiments, and this application will not elaborate on them.

[0157] Finally, it should be noted that the above embodiments are intended only to illustrate the present application and are not intended to limit the present application. Although the present application has been described in detail with reference to the embodiments, those skilled in the art will appreciate that various combinations, modifications, or equivalent substitutions of the technical solutions of the present application do not depart from the spirit and scope of the technical solutions of the present application and are intended to be encompassed by the claims of the present application.
