Refrigerator

Abstract

This application provides a refrigerator. The refrigerator includes a main shaft, an auxiliary shaft, a main shaft groove, and an auxiliary shaft groove for opening and closing the door. The door includes a first state, a second state, and a third state with sequentially increasing opening angles. The stage with the largest door translation amplitude is placed during the opening from the closed state to the first state. This satisfies the need for rapid inward movement of the door while reducing the user's perception of door movement. During the opening to the second state, the door continues to move slightly inward, reducing the perceived offset. During the opening to the third state, the door moves slightly outward, reducing both the perceived offset and the obstruction of storage space. In summary, the door moves significantly during the initial opening stage where the user easily overlooks the offset, and then moves slightly in the remaining stages before opening to 90°, thereby minimizing the user's perception of offset and improving the user experience.

Description

Technical Field

[0001] This application pertains to household appliances, and more specifically, to a refrigerator. Background Technology

[0002] Refrigerators are common household appliances. With the development of home decoration technology, built-in refrigerators have gradually become a new development trend in the industry. During the opening and closing process of a built-in refrigerator, the door can move inward as a whole, so that the door will not collide with the embedded object, ensuring that the refrigerator can be opened smoothly when embedded.

[0003] However, the way the refrigerator door moves during opening has also created new problems. Because the movement trajectory of this type of door differs from that of a conventional door, users often experience a noticeable sense of displacement when opening the door, thus reducing the user experience.

Detailed Implementation

[0056] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0057] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0058] It should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0059] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0060] In today's home decoration trend that pursues spatial aesthetics and functional integration, built-in refrigerators are highly favored for their unique advantages in space integration and aesthetic design. A typical application of built-in refrigerators is their integration with kitchen cabinets, which saves space and creates a more harmonious and unified overall kitchen style, making them a popular choice for modern home renovations.

[0061] For a more aesthetically pleasing result, the gap between built-in refrigerators and cabinets is usually small, sometimes even requiring only a tiny gap or achieving a zero-gap integration. Because of this typically small gap, ensuring smooth door opening becomes a crucial consideration. To address this, built-in refrigerators typically employ dual-axis hinges. These hinges usually consist of a main axis and an auxiliary axis, along with corresponding main axis and auxiliary axis slots. The main axis resides in the main axis slot, and the auxiliary axis in the auxiliary axis slot. During opening, the door rotates around the main axis, while the auxiliary axis drives the main axis to move within its slot, causing the door to move inward. This prevents the door from colliding with the cabinet during opening, ensuring the refrigerator can be opened smoothly after being integrated into the cabinet.

[0062] This makes the movement trajectory of the door of a built-in refrigerator different from that of a conventional door. Conventional doors typically use a single-axis hinge, where the door rotates only along the hinge axis; this is common for room doors and wardrobe doors. However, in addition to moving around the main axis, the door of a built-in refrigerator also moves as a whole under the drive of the auxiliary axis. This can cause a sense of displacement for the user, affecting the user experience.

[0063] To address the aforementioned problems, this application provides a refrigerator, and the refrigerator provided in the embodiments of this application will now be described. Please refer to... Figures 1 to 10 The refrigerator 10 includes a cabinet 1, a door 2, a first hinge 3, and a second hinge 4.

[0064] like Figure 1 As shown, the refrigerator body has an opening and is the main structure of the refrigerator 10, used to house the refrigeration system, storage space, and internal components. The opening serves as the passage for users to access food, usually located on the front of the body and connected to the storage space; its size and shape determine the design specifications of the door 2. The body may include an inner liner, an outer shell, and an insulator. The inner liner defines the storage space; the outer shell connects to the outside of the inner liner to form the appearance of the refrigerator 10; and the insulator is placed between the inner liner and the outer shell to insulate the storage space. Internal components are located within the inner liner. For example, partitions can divide the storage space into a refrigerator compartment and a freezer compartment; drawers, storage boxes, and shelves can divide the refrigerator compartment or freezer compartment into multiple storage layers. The refrigeration system is typically located between the inner liner and the outer shell, used to transfer heat from the storage space to the outside of the refrigerator 10.

[0065] Please see Figure 1 and Figure 2 The door 2 is used to close the opening. The door 2 includes a front wall 21 and a first side wall 22 near the hinge side of the door 2. The front wall 21 is the side wall facing the user when the refrigerator door 2 is closed, and a display screen, control panel, or decorative layer can be installed on it. The hinge side of the door 2 is the side where the hinge is installed, and the first side wall 22 near this side is usually opposite the cabinet 20 when the refrigerator 10 is embedded. The door 2 can also be filled with foam materials such as PU polyurethane to improve thermal insulation performance.

[0066] like Figure 3 , Figure 4 and Figure 5 As shown, the first hinge 3 is mounted on the housing and includes a main shaft 31 and an auxiliary shaft 32 that are relatively fixed. The second hinge 4 is mounted on the door 2 and includes a main shaft groove 41 and an auxiliary shaft groove 42. The main shaft 31 is located in the main shaft groove 41, and the auxiliary shaft 32 is located in the auxiliary shaft groove 42, used to drive the main shaft 31 to move within the main shaft groove 41. The main shaft 31, also known as the main rotation shaft, bears the main supporting force for the rotation of the door 2. The main shaft 31 is located within the main shaft groove 41, allowing it to move within the groove, thus enabling the overall movement of the door 2. The main shaft 31 and the auxiliary shaft 32 are relatively fixed; for example, they can usually be fixed to the same connecting plate. The auxiliary shaft 32 is located within the auxiliary shaft groove 42. When the door 2 rotates, the auxiliary shaft 32 moves along the auxiliary shaft groove 42, thereby driving the main shaft 31 to move within the main shaft groove 41, allowing the door 2 to simultaneously rotate and translate during opening and closing. Figure 2 For example, Figure 2The central plane O is flush with the side of the refrigerator 10. When the refrigerator 10 is embedded in the cabinet 20, the distance between the side of the refrigerator 10 and the cabinet 20 is D. D is usually small; for example, after the refrigerator 10 is embedded, D can be 5mm, 3mm, or even smaller. During the opening of the door 2, as the auxiliary shaft 32 moves in the auxiliary shaft groove 42, it can drive the main shaft 31 to move in the main shaft groove 41. That is, the door 2 can be translated relative to the cabinet during the opening process. When the main shaft 31 moves outward relative to the main shaft groove 41, the door 2 moves inward relative to the cabinet. This ensures that the door 2 does not exceed the plane O, or the distance by which the door 2 exceeds the plane O is less than or equal to D.

[0067] like Figure 6 As shown, the main shaft groove 41 includes a first section 411, a second section 413, and an inflection point section 412 located between the first section 411 and the second section 413. The first section 411 extends from the inflection point section 412 along a direction close to the first side wall 22, and the second section 413 extends from the inflection point section 412 along a direction close to the front wall 21. During the opening process, if the main shaft 31 moves along the first section 411, the main shaft 31 can move relative to the main shaft groove 41 towards the first side wall 22. Correspondingly, the door body 2 can move relative to the main shaft 31 in the opposite direction along the first side wall 22. The first side wall 22 is the side opposite to the cabinet 20 when the door body 2 is closed. In this way, the first side wall 22 of the door body 2 can move away from the cabinet 20, thereby preventing the door body 2 from colliding with the cabinet 20. During the opening process, if the main shaft 31 moves along the second section 413, the main shaft 31 can move relative to the main shaft groove 41 towards the front wall 21. Correspondingly, the door body 2 can move relative to the main shaft 31 in the opposite direction to the front wall 21. In this way, when the door body 2 opens at a large angle, the front wall 21 of the door body 2 can move away from the cabinet 20, thereby preventing the door body 2 from colliding with the cabinet 20. The inflection point section 412 is the transition section between the first section 411 and the second section 413. During the opening process, if the main shaft 31 moves at the inflection point, the door body 2 can also move slightly.

[0068] The door 2 includes a first state, a second state, and a third state in which the opening angle increases sequentially. The opening angle of the door 2 in the third state is less than or equal to 90°. That is, the first state, the second state, and the third state are the three states before the door 2 is opened to 90°. The specific situation of each state is as follows.

[0069] Please see Figure 6 and Figure 7 When the door 2 is closed, the main shaft 31 is located at the first main shaft position 311 of the main shaft groove 41. The first main shaft position 311 is located in the first section 411. If the door 2 is opened at this time, the main shaft 31 can move along the first section 411.

[0070] Please see Figure 6 and Figure 8 When the door 2 is in the first state, the main shaft 31 is located at the second main shaft position 312 of the main shaft groove 41, and the second main shaft position 312 is located at the inflection point section 412. The process of the door 2 opening from the closed state to the first state is also the process of the main shaft 31 moving from the first main shaft position 311 to the second main shaft position 312. Since the first main shaft position 311 is located in the first section 411 and the second main shaft position 312 is located in the inflection point section 412, during this process, the main shaft 31 moves from the first section 411 to the inflection point section 412. The first section 411 extends from the direction close to the first side wall 22 to the inflection point section 412, allowing the door 2 to move significantly away from the first side wall 22. When the door 2 is in the closed state, the first side wall 22 of the door 2 is the position closest to the cabinet 20. During the process of the door 2 opening from the closed state to the first state, the door 2 moves significantly away from the first side wall 22, allowing the door 2 to quickly move away from the cabinet 20.

[0071] There are two points that need special explanation.

[0072] Firstly, for a regular single-hinged door, the side wall approaches the cabinet 20 most rapidly when it is first opened. In this embodiment, the door 2 moves away from the cabinet 20 quickly during this process, which can offset the distance of the door 2 approaching the cabinet 20 quickly, thereby effectively preventing the door 2 from colliding with the cabinet 20.

[0073] Secondly, although in this embodiment, door 2 will shift significantly during the process of opening from the closed state to the first state, users usually ignore the sense of shift during this stage. This is because when the user opens door 2, they initially need to use considerable force to overcome the suction force between door 2 and the box. When door 2 separates from the opening of the box, the suction force disappears, and the user will feel that the reaction force of door 2 suddenly decreases significantly, while door 2 is opened quickly. This sudden change in reaction force will cause the user to subconsciously ignore the sense of shift of door 2. At the same time, the initial stage of the separation of the opening of door 2 and box 1 is also the stage in which door 2 is opened the fastest, and the corresponding time is usually the shortest. This short time will make the user even more unaware of the sense of shift of door 2.

[0074] Please see Figure 6 and Figure 9When the door 2 is in the second state, the main shaft 31 is located at the third main shaft position 313 of the main shaft groove 41. The third main shaft position 313 is located in the inflection point section 412, and the third main shaft position 313 is closer to the second section 413 than the second main shaft position 312. The process of the door 2 opening from the first state to the second state is also the process of the main shaft 31 moving from the second main shaft position 312 to the third main shaft position 313. Both the second main shaft position 312 and the third main shaft position 313 are located in the inflection point section 412. The inflection point section 412 is a transition section between the first section 411 and the second section 413, and its length is very short. During this process, the main shaft 31 will only move slightly, and correspondingly, the door 2 will also move slightly. The slight movement is not easily perceived by the user, and the user will not experience any unpleasant sense of displacement. The third main axis position 313 is closer to the second section 413 than the second main axis position 312. In other words, at this stage, the actual main axis 31 is still moving towards the first side wall 22 and the front wall 21 relative to the door body 2. The corresponding door body 2 will also move inward relative to the refrigerator 10, thereby further preventing the door body 2 from colliding with the cabinet 20.

[0075] As the opening angle of door 2 increases, assuming the main shaft 31 does not move, the speed at which door 2 approaches cabinet 20 will decrease. Therefore, during the process of door 2 opening from the first state to the second state, a small movement of door 2 is sufficient to meet the requirement of not colliding with cabinet 20.

[0076] Please see Figure 6 and Figure 10 When the door 2 is in the third state, the main shaft 31 is located at the fourth main shaft position 314 of the main shaft groove 41. The fourth main shaft position 314 is located in the inflection point section 412, and the fourth main shaft position 314 is closer to the first section 411 than the third main shaft position 313. The process of the door 2 opening from the second state to the third state is also the process of the main shaft 31 moving from the third main shaft position 313 to the fourth main shaft position 314. Both the third main shaft position 313 and the fourth main shaft position 314 are located in the inflection point section 412. Therefore, during this process, the main shaft 31 will only move slightly. The slight movement is not easily perceived by the user, and the user will not experience any unusual sense of displacement.

[0077] Please note that the fourth main axis position 314 is closer to the first section 411 than the third main axis position 313. Therefore, during the process of the door 2 opening from the second state to the third state, the main axis 31 is retracted towards the first section 411. Correspondingly, the door 2 will move outward to a certain extent. This reduces the obstruction of the cabinet storage space by the inward retraction of the door 2, thereby increasing the cabinet access opening and making it easier for users to take out and put in items inside the refrigerator 10.

[0078] In this embodiment, the stage with the largest translational amplitude of door 2 is placed during the process from the closed state to the first state. This satisfies the need for door 2 to move rapidly inward while reducing the user's perception of the movement. During the opening to the second state, door 2 continues to move inward slightly, reducing the sense of offset. During the opening to the third state, door 2 moves outward slightly, reducing both the sense of offset and the obstruction of the storage space. In summary, in this embodiment, door 2 moves significantly during the relatively open phase where the user easily overlooks the offset, and moves slightly during the remaining phases before opening to 90°, thereby minimizing the user's perception of offset and improving the user experience.

[0079] In some embodiments of this application, the opening angle of the door 2 in the first state is 28°±3°. At this small angle, during the initial opening of the door 2, the first sidewall 22, especially the side edge, quickly approaches the cabinet 20. During this stage, the auxiliary shaft 32 drives the main shaft 31 to move along the first section 411 of the main shaft groove 41 towards the hinge side, causing the door 2 to translate inwards. When the opening angle of the door 2 is greater than 31°, the outward expansion speed of the door 2 has slowed down, eliminating the need for a large inward movement of the door 2, and the user can more easily perceive the offset of the door 2.

[0080] In some embodiments of this application, the opening angle of the door 2 in the second state is 49°±3°. When the door 2 reaches about 49° from the first state, the outward expansion of the door 2 has basically stopped. Before this stage, it is only necessary to move the door 2 inward slightly to meet the requirements. However, when the opening angle of the door 2 is greater than 52°, the door 2 will hardly expand outward.

[0081] In some embodiments of this application, the opening angle of door 2 in the third state is 80°±3°. As mentioned earlier, when the opening angle of door 2 is greater than 52°, door 2 hardly expands outwards anymore. After that, door 2 will retract inwards as the opening angle increases. Therefore, door 2 can be moved outwards to a certain extent to reduce the obstruction of the storage space by the inward retraction of door 2, thereby increasing the access opening of the cabinet. However, since door 2 should not move inwards too much, the opening angle in the third state is set at around 80°.

[0082] Please see Figure 6 In some embodiments of this application, the auxiliary shaft groove 42 includes a third section 421, a fourth section 422 and a fifth section 423 connected in sequence. During the opening of the door 2, the auxiliary shaft 32 passes through the third section 421, the fourth section 422 and the fifth section 423 in sequence.

[0083] Please see Figure 7When the door 2 is closed, the auxiliary shaft is located at the first auxiliary shaft position 321, and the first auxiliary shaft position 321 is located in the third section 421.

[0084] Please see Figure 7 and Figure 8 When the door 2 is in the first state, the auxiliary shaft is located at the second auxiliary shaft position 322, and the first auxiliary shaft position 321 is located between the third section 421 and the fourth section 422. The second auxiliary shaft position 322 is closer to the inflection point section than the first auxiliary shaft position 321. When the door 2 opens from the closed state to the first state, the auxiliary shaft 32 moves from the starting point of the third section 421 towards the fourth section 422, reaching the end of the third section 421, that is, from the first auxiliary shaft position 321 to the second auxiliary shaft position 322. The second auxiliary shaft position 322 is closer to the inflection point section than the first auxiliary shaft position 321. Therefore, the translation of the auxiliary shaft 32 causes the main shaft 31 to move along the first section 411 of the main shaft groove 41 towards the inflection point section 412, entering the second main shaft position 312, that is, from the first section 411 to the inflection point section 412. Figure 8 As shown, because there are concave points in the third section 421 and the fourth section 422 of the auxiliary shaft groove 42, the auxiliary shaft 32 reaches the concave point at the same time.

[0085] Please see Figure 8 and Figure 9 When the door 2 is in its second state, the auxiliary shaft is located at the third auxiliary shaft position 323. The third auxiliary shaft position 323 is located between the fourth segment 422 and the fifth segment 423. Compared to the second auxiliary shaft position 322, the third auxiliary shaft position 323 is closer to the inflection point segment, and the fourth segment 422 is deflected away from the inflection point segment 412 compared to the third segment 421. The auxiliary shaft 32 moves from the starting point of the fourth segment 422 towards the fifth segment 423, reaching the end of the fourth segment 422, i.e., the third auxiliary shaft position 323. The third auxiliary shaft position 323, being closer to the inflection point segment than the second auxiliary shaft position 322, causes the auxiliary shaft 32 to continue pushing the main shaft 31 towards the inflection point segment. However, because the fourth segment 422 is deflected away from the inflection point segment 412 compared to the third segment 421, the amplitude of the auxiliary shaft 32 pushing the main shaft 31 is reduced, thereby reducing the amplitude of the door 2 moving inward.

[0086] Please see Figure 9 and Figure 10 When the door 2 is in the third state, the auxiliary shaft is located at the fourth auxiliary shaft position 324. The fourth auxiliary shaft position 324 is located at the end of the fifth section 423 away from the fourth section 422. The fourth auxiliary shaft position 324 is farther away from the inflection point section than the third auxiliary shaft position 323. The auxiliary shaft 32 moves from the starting point of the fifth section 423 to the end of the fourth auxiliary shaft position 324. The fourth auxiliary shaft position 324 is farther away from the inflection point section than the third auxiliary shaft position 323, which allows the auxiliary shaft 32 to drive the main shaft 31 back, thereby causing the door 2 to move outward to a certain extent and reduce the obstruction of the opening.

[0087] Please see Figure 8 and Figure 9 In some embodiments of this application, the door 2 includes a first side edge 23 located at the junction of the front wall 21 and the first side wall 22; the third main axis position 313 is located on the side of the second main axis position 312 closer to the first side edge 23. During the process of the door 2 opening from the first state to the second state, the first side edge 23 of the door 2 is located at the junction of the front wall 21 and the first side wall 22, which is the area closest to the cabinet 20 when opened, while the third main axis position 313 is located on the side of the second main axis position 312 closer to the first side edge 23. When the main axis 31 moves from the first main axis position 311 to the second main axis position 312, the main axis 31 moves towards the direction closer to the first side edge 23, corresponding to the door 2 moving away from the first side edge 23. This allows the door 2 to move away from the cabinet 20 as far as possible with a limited translation range. This matches the small movement of the door 2 in this stage, thus ensuring that although the door 2 moves a small amount in this stage, it can still achieve a good effect of moving away from the cabinet 20.

[0088] Please see Figure 11 and Figure 12 In some embodiments of this application, the door 2 also includes a fifth state, in which the opening angle of the door 2 is greater than 90°; when the door 2 is in the fifth state, the main shaft 31 is located at the sixth main shaft position 316 of the main shaft groove 41, and the sixth main shaft position 316 is located in the second section 413. When the opening angle of the door 2 exceeds 90°, the front wall 21 of the door 2 becomes the part closest to the cabinet 20. At this time, the main shaft 31 moves from the inflection point section 412 to the sixth main shaft position 316 of the second section 413. Since the second section 413 extends along the direction close to the front wall 21 of the door 2, the main shaft 31 moves relative to the door 2 towards the front wall 21. According to the principle of relative motion, the entire door 2 translates in the opposite direction to the front wall 21. During this process, the main shaft 31 guides the door 2 to continue rotating along the movement trajectory of the second section 413, while simultaneously adding a translational component moving away from the cabinet 20. This allows the front wall 21 to actively move away from the cabinet 20 even when the door is opened at a large angle, thereby increasing the opening angle of the door 2 without colliding with the cabinet 20. Figure 13 In the embodiment shown, the opening angle α of the door 2 can reach more than 113°.

[0089] In addition, since users usually change from pulling to pushing the door after it is opened to 90°, this transition process can also reduce the user's sensitivity to the offset of the door.

[0090] Please see Figure 11 and Figure 12In some embodiments of this application, the door body 2 also includes a fourth state, and the opening angle of the door body 2 increases sequentially in the third state, the fourth state and the fifth state; when the door body 2 is in the fourth state, the main shaft 31 is located at the fifth main shaft position 315 of the main shaft groove 41, the fifth main shaft position 315 is located in the inflection point section, and the fifth main shaft position 315 is closer to the second section 413 than the fourth main shaft position 314. Because the main shaft 31 moves towards the first section 411 during the process of the door 2 opening from the second state to the third state, and the door 2 needs to reach the second section 413 in the fifth state, a fourth state is provided between the third and fifth states in order to make the main shaft 31 move more smoothly. The fifth main shaft position 315 corresponding to the fourth state is also located in the inflection point section. However, compared to the fourth main shaft position 314 being closer to the second section 413, that is, during the process of the door 2 opening from the third state to the fourth state, the main shaft 31 moves towards the second section 413 again, so that the main shaft 31 can better transition to the sixth main shaft position 316 of the second section 413, reducing mechanical impact and ensuring that the combined translation and rotation movements of the door 2 are naturally connected during the large-angle opening process. Figure 11 In the embodiment shown, the door 2 is in the fourth state, and the main shaft 31 is approximately located at the center of the inflection point, which facilitates subsequent movement to the second section 413.

[0091] like Figure 11 As shown, because the door 2 moves outward during the process of opening from the second state to the third state, when the door 2 is opened to the fourth state, the distance d between the door 2 and the side wall of the refrigerator 10, that is, between the door 2 and the O plane, in the inward and outward directions can be less than 2mm.

[0092] In some embodiments of this application, the opening angle of the door 2 in the fourth state is 90°±3°. In this embodiment, the opening angle of the door 2 in the fourth state is set to 90°±3°, which is in the critical range between the third and fifth states. At this angle, the main shaft 31 is located at the fifth main shaft position 315 in the inflection point section, which is closer to the second section 413 than the main shaft position 31 in the third state. This allows the door 2 to transition between less than 90° and greater than 90°, which can avoid abrupt changes in the movement of the main shaft 31 in the inflection point section and provide pre-adjustment for the anti-collision translation of the front wall 21 after the door 2 exceeds 90°, ensuring continuous movement and uniform mechanical stress when opening at a large angle.

[0093] Please see Figure 6 and Figure 11In some embodiments of this application, the auxiliary shaft groove 42 further includes a sixth section 424, which is connected to the end of the fifth section 423 away from the fourth section 422. When the door body 2 is in the fourth state, the auxiliary shaft is located at the fifth auxiliary shaft position 325, which is located at the end of the sixth section 424 away from the fifth section 423. The fifth auxiliary shaft position 325 is closer to the inflection point section than the fourth auxiliary shaft position 324. When the door 2 opens from the third state to the fourth state, the auxiliary shaft 32 enters the sixth section 424 along the end of the fifth section 423, thereby reaching the fifth auxiliary shaft position 325 of the sixth section 424. Since the fifth auxiliary shaft position 325 is closer to the inflection point section than the fourth auxiliary shaft position 324, the auxiliary shaft 32 can drive the main shaft 31 to move towards the inflection point section, that is, to enter the inflection point section more deeply, thereby getting closer to the second section 413. This lays the trajectory for the main shaft 31 to enter the second section 413 when entering the fifth state later, ensuring the continuous and stable linkage between the auxiliary shaft 32 and the main shaft 31 during the large-angle opening process, reducing mechanical wear while improving the smoothness and safety of the opening and closing of the door 2.

[0094] Please see Figure 6 and Figure 12 In some embodiments of this application, the auxiliary shaft groove 42 further includes a seventh section 425, which is connected to the end of the sixth section 424 away from the fifth section 423; when the door body 2 is in the fifth state, the auxiliary shaft is located at the sixth auxiliary shaft position 326, which is closer to the front wall 21 than the fifth auxiliary shaft position 325. In this embodiment, the auxiliary shaft groove 42 is supplemented with a seventh section 425 connected to the end of the sixth section 424 away from the fifth section 423, and the sixth auxiliary shaft position 326 when the door body 2 is in the fifth state is set in a position closer to the front wall 21 than the fifth auxiliary shaft position 325. When the door body 2 enters the fifth state from the fourth state, the auxiliary shaft 32 moves along the end of the sixth section 424 to the seventh section 425. The seventh section 425 extends toward the front wall 21 of the door body 2, and the sixth auxiliary shaft position 326 is set in a position closer to the front wall 21 than the fifth auxiliary shaft position 325. The movement trajectory of the auxiliary shaft 32 guides the main shaft 31 to shift toward the front wall 21, so that the door body 2 moves in the opposite direction to the front wall 21, avoiding the front wall 21 from hitting the cabinet when it is opened at a large angle.

[0095] Please see Figure 14 In some embodiments of this application, the included angle β between the second segment 413 and the seventh segment 425 is 45°-59°. The second segment 413 and the seventh segment 425 are the trajectories of the main shaft 31 and the auxiliary shaft 32, respectively, as the door 2 moves from the fourth state to the fifth state. If the included angle is too large, the opening angle will be too small, and the door 2 will collide with the cabinet 20 before it reaches 113°. If the included angle is too small, the movement states of the main shaft 31 and the auxiliary shaft 32 will be too similar, resulting in poor door opening and closing accuracy. Moreover, the distance between the two shaft grooves will be very close, leading to local weakness and easy damage.

[0096] Please continue reading. Figure 14 In some embodiments of this application, the included angle γ between the first segment 411 and the second segment 413 is 90°±5°. When the included angle γ<85°, the protrusion formed between the two included angles will be too sharp, resulting in poor strength of the track groove and easy wear. When the included angle γ>95°, the space occupied by the first segment 411 and the second segment 413 will increase, making the auxiliary shaft groove 42 and the main shaft groove 41 too close, causing local weakness and easy breakage, or increasing the area of ​​the entire second hinge 4, thereby increasing the thickness of the door body 2.

[0097] In some embodiments of this application, the length ratio of the first segment 411 and the second segment 413 is 0.8-1.2, so that the displacement ratio of the main shaft 31 in the first segment 411 and the second segment 413 is within 0.8-1.2, which reduces the area occupied by the main shaft groove 41 to a certain extent. Furthermore, the length of the first segment 411 is related to the distance the side wall retracts before the door 2 opens to 90°, and the length of the second segment 413 is related to the distance the front wall 21 retracts after the door 2 opens to 90°. This allows the door 2 to achieve a large-scale upward translation both before and after 90°, avoiding collisions with the cabinet 20.

[0098] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
