[0001] This application claims priority to Chinese patent application No. 202311057555.5 filed on August 21, 2023, priority to Chinese patent application No. 202311266553.7 filed on September 27, 2023, priority to Chinese patent application No. 202311628629.6 filed on November 30, 2023, and priority to Chinese patent application No. 202410083235.5 filed on January 19, 2024, the entire contents of which are incorporated herein by reference. Technical Field

[0002] The present disclosure relates to the technical field of household appliances, and in particular to a refrigerator. Background Art

[0003] Built-in refrigerators are typically built entirely into a custom cabinet. To ensure a seamless fit, the gap between the refrigerator's outer wall and the cabinet's inner wall is typically kept very small. When the refrigerator door is opened, the hinged vertical edge of the rotating door can easily strike the inner wall of the cabinet due to the cabinet's limited space. To ensure the door opens efficiently, the corners of the door must not protrude significantly beyond the dimensions of the cabinet.

[0004] To meet the installation requirements of built-in refrigerators, most built-in refrigerators currently feature dual shafts on one of the door and the refrigerator body, along with a guide structure on the other. This structure controls the inward movement of the door as it rotates open. The combination of the dual shafts and the guide structure ensures the door moves inward during opening, ensuring that the corners of the door do not extend significantly beyond the dimensions of the refrigerator body.

[0005] When customizing the storage cabinet in which the built-in refrigerator is embedded, the standard is usually that when the refrigerator door is closed, the front wall of the door is flush with the plane where the opening end of the storage cabinet is located, so that the size of the refrigerator matches the size of the storage cabinet and a hidden flush installation is achieved. Under the premise that the door of the built-in refrigerator can be opened smoothly and does not interfere with the inner wall of the storage cabinet, as the opening angle of the refrigerator door increases, the front wall of the door approaches the end of the adjacent storage cabinet close to its own opening; when the front wall of the door contacts the end of the adjacent storage cabinet close to its own opening, the door body opens to the limit position. In summary, the limit angle that the door of the refrigerator installed in the storage cabinet can be opened is limited by the size of the storage cabinet for realizing the hidden installation of the refrigerator and the gap between the outer wall of the refrigerator and the inner wall of the storage cabinet, resulting in a small limit angle that the door of the refrigerator installed in the storage cabinet can be opened, which is inconvenient for users to take and put items.

[0093] For example, when the first hinge is located on the right side of the box body 10 , the right side of the door body 30 is the door side wall 32 when it is closed; when the first hinge is located on the left side of the box body 10 , the left side wall of the door body 30 is the door side wall 32 when it is closed.

[0094] It should be noted that the above door front wall 31 is the surface of the door body 30 that is away from the box body 10 in its closed state after the product is formed.

[0095] In some embodiments of the present disclosure, the door body 30 further includes a door frame and a glass panel. Correspondingly, when the door body 30 is closed, the surface of the glass panel away from the box body is the door front wall 31.

[0096] The front wall 31 and the side wall 32 of the door body 30 intersect to form a first side edge W, and the side wall 32 and the rear wall 33 intersect to form a second side edge N. When the door body 30 is closed, the first side edge W is located on the side of the second side edge N away from the box body 10.

[0097] It should be noted that when both the front door wall 31 and the side door walls 32 are planar, the intersection of these two planes is the theoretical first side edge W (similarly, the theoretical second side edge N is the intersection of the side door walls 32 and the rear door wall 33). In actual production and processing, the intersection of the front door wall 31 and the side door walls 32 may be configured with a rounded transition, thereby forming a curved surface at the intersection of the front door wall 31 and the side door walls 32. On the curved surface at the intersection of the front door wall 31 and the side door walls 32, any straight line extending along the height direction of the door body 30 can represent the first side edge W (the same applies to the second side edge N).

[0098] For the convenience of description in this disclosure, the theoretical first side edge W and the theoretical second side edge N are used for description.

[0099] In addition, a plane passing through the center of mass of the door body 30 and parallel to the door front wall 31 is recorded as a middle plane C. When the door body 30 is opened, the middle plane C moves along with the door body 30 .

[0100] It should be noted that, in the present disclosure, when the relevant technical solutions involving the middle plane C are concerned, the distance between the middle plane C and the door front wall 31 or the door rear wall 33 is less than the distance between the middle plane C and the plane where the access opening of the box body 10 is located when the door body 30 is closed. In other words, in the present disclosure, when the relevant technical solutions involving the middle plane C are concerned, the door rear wall 33 corresponding to the middle plane C is located on the side of the plane where the access opening of the box body 10 is located that is away from the rear wall of the box body 10 when the door body 30 is closed.

[0101] In some embodiments of the present disclosure, a door seal 5 is provided on the door rear wall 33 .

[0102] When the door body 30 is closed, the door seal 5 fits against the front end surface of the box body 10 surrounding the access opening to effectively seal the connection between the door body 30 and the box body 10, thereby ensuring that the door body 30 seals the access opening to prevent cold air from escaping.

[0103] In some embodiments of the present disclosure, the door seal 5 is annular. The edge of the door seal 5 close to the door side wall 32 and away from the door front wall 31 is marked as a side sealing edge F.

[0104] The door seal 5 is located between the door rear wall 33 and the front end surface of the box body 10 , and the door rear wall 33 is located on a side of the plane where the access opening of the box body 10 is located close to the door seal 5 .

[0105] In some embodiments of the present disclosure, referring to FIG. 2 to FIG. 3 , the first hinge member includes a hinge plate 40 .

[0106] In some embodiments of the present disclosure, the hinge plate 40 includes a connecting portion connected to the box body 10 and adjacent to the first side wall. The connecting portion can be fastened to the top wall of the box body 10 by fasteners such as screws, pins, and bolts.

[0107] In some embodiments of the present disclosure, the hinge plate 40 further includes an extension portion extending forward from the connecting portion, for example, the extension portion is in the shape of a horizontal plate.

[0108] 6 , in some embodiments of the present disclosure, the first hinge member includes a first shaft 41 and a second shaft 42 . The first shaft 41 and the second shaft 42 are disposed on the hinge plate 40 .

[0109] For example, for the hinge at the upper end of the door body 30, the connecting portion can be connected to the top wall of the box body 10. For the hinge at the lower end of the door body 30, the connecting portion can be connected to the front end surface of the box body 10.

[0110] In some embodiments of the present disclosure, a first shaft 41 and a second shaft 42 are formed on the extension portion of the first hinge member.

[0111] In some embodiments of the present disclosure, the second shaft 42 is located on a side of the first shaft 41 away from the side wall of the first body.

[0112] In some embodiments of the present disclosure, the second hinge further includes a guide portion 50 located on the door body 30 . The guide portion 50 is close to the first hinge, and the first shaft 41 is adapted to the guide portion 50 .

[0113] In some embodiments of the present disclosure, the second hinge member further includes a guide portion 60 located on the door body 30. The guide portion 60 is close to the first hinge member. The second shaft 42 is adapted to the guide portion 60.

[0114] When the door body 30 rotates to open or close, the first shaft 41 moves relative to the guide portion 50 , and the second shaft 42 moves relative to the guide portion 60 .

[0115] In some embodiments of the present disclosure, the first shaft 41 performs a curved motion relative to the door body 30 under the guidance of the guide portion 50 , and the second shaft 42 performs a curved motion relative to the door body 30 under the guidance of the guide portion 60 .

[0116] The first shaft 41 and the second shaft 42 are formed on a first hinge member connected to the cabinet 10 to form a defined axis for guiding the movement of the door body 30 .

[0117] In some embodiments of the present disclosure, the first shaft 41 and the second shaft 42 extend in a vertical direction (a height direction of the box body 10 ) to fit the guide portion 50 or the guide portion 60 provided on the door body 30 .

[0118] It is understood that a built-in refrigerator is a refrigerator that is entirely embedded in a custom-made storage cabinet. The end face of the storage cabinet defining its opening is referred to as the opening end face. The refrigerator is flush-mounted in the storage cabinet. When the refrigerator door is closed, the front wall 31 of the door body 30 is flush with the opening end face of the storage cabinet.

[0119] In the present disclosure, the first shaft 41 cooperates with the guide portion 50, and the second shaft 42 cooperates with the guide portion 60 to move the door 30 inward (i.e., toward the side wall of the second body) by a predetermined distance. This prevents the refrigerator door 30 from colliding with the storage cabinet when the user opens or closes the refrigerator door 30, thereby effectively preventing damage to the storage cabinet or the refrigerator door 30.

[0120] In addition, when the door 30 of the refrigerator placed in the storage cabinet is opened from a closed state, the maximum angle that the door 30 can open is greater than or equal to 115° (the maximum angle can be set to be greater than or equal to 120°), so that the door 30 of the refrigerator can be fully opened when it is embedded to facilitate taking out items.

[0121] It should be noted that the “flush” in the above-mentioned flushness between the door front wall 31 and the opening end surface of the storage cabinet 100 includes being on the same plane, or the distance between the two planes being less than or equal to 2 mm.

[0122] For example, the door front wall 31 is located on the side of the opening end face of the storage cabinet 100 away from the access opening and the distance between the two planes is less than or equal to 2 mm. Alternatively, the door front wall 31 is located on the side of the opening end face of the storage cabinet 100 close to the access opening and the distance between the two planes is less than or equal to 2 mm.

[0123] In some embodiments of the present disclosure, a description is given by taking as an example a configuration in which a first shaft 41 and a second shaft 42 are provided on the extensions at the upper and lower ends of the door body 30, and a guide portion 50 and a guide portion 60 are provided at the upper and lower ends of the door body 30. It should be noted that the configuration of the first shaft 41, the second shaft 42, the guide portion 50, and the guide portion 60 is not limited to being provided at the upper and lower ends of the door body 30 at the same time. They can be provided as needed to connect the door body 30 and the box body 10, and the present disclosure does not impose any limitation on this.

[0124] In some embodiments of the present disclosure, as shown in Figures 2 to 3, the plane on which the side surface (first body side wall) of the box body 10 close to the hinge plate 40 is located is defined as a reference plane M0 (refer to Figure 15), and the side of the reference plane M0 away from the inner cavity of the storage chamber is recorded as the outer side, and the opposite side close to the storage chamber is recorded as the inner side.

[0125] When the refrigerator is placed in the storage cabinet 100 for use, to prevent factors such as uneven ground and deformation of the storage cabinet 100, the distance α' between the storage cabinet 100 and the side of the refrigerator (the first side wall, i.e., the reference plane M0) is set when the storage cabinet 100 is sized. To ensure that the refrigerator door 30 opens properly, the first side edge W of the door 30 cannot extend too far beyond the side of the refrigerator body 10 (the reference plane M0) during rotation to prevent the first side edge W from colliding with the storage cabinet 100 and preventing the door 30 from opening properly.

[0126] In some embodiments of the present disclosure, α' is any value between 3 and 5 mm.

[0127] In some embodiments of the present disclosure, α` = 3 mm. That is, the distance between the sidewall of the door body 30 and the storage cabinet is 3 mm. This satisfies the space requirements for placing the refrigerator in the storage cabinet 100 and minimizes the gap between the cabinet body 10 and the storage cabinet 100 after the refrigerator is placed in the storage cabinet 100, thereby improving the compatibility between the refrigerator and the storage cabinet 100 and achieving concealed installation.

[0128] To meet the above requirements, the door body 30 must be able to move inward during rotation so that the first side edge W does not extend too far beyond the side surface of the box body 10 (reference plane M0). For example, if the hinge plate 40 is located on the right side of the door body 30 (in this example, the right side wall of the box body 10 is the first side wall), the inner side is the left side, meaning the door body 30 must be able to move to the left. If the hinge plate 40 is located on the left side of the door body 30, the inner side is the right side, meaning the door body 30 must be able to move to the right.

[0129] In some embodiments of the present disclosure, the central axis of the first shaft 41 is denoted as the first central axis P, and the central axis of the second shaft 42 is denoted as the second central axis Q.

[0207] In some embodiments, the guide trajectory line K extends from the starting guide point Q0 to the direction away from the door front wall 31 and close to the door side wall 32, passing through the first guide point Q1, the second guide point Q2, the third guide point Q3, the fourth guide point Q4, the fifth guide point Q5 to the sixth guide point Q6, and then extends from the sixth guide point Q6 to the direction close to the door side wall 32 and the door front wall 31 to the eighth guide point Q8.

[0208] In some embodiments, the guide trajectory line K extends from the starting guide point Q0 along a curve in the direction away from the door front wall 31 and close to the door side wall 32, passing through the first guide point Q1, the second guide point Q2, the third guide point Q3, the fourth guide point Q4, the fifth guide point Q5 in sequence to the sixth guide point Q6, and then extends from the sixth guide point Q6 along the curve in the direction close to the door side wall 32 and the door front wall 31 to the eighth guide point Q8.

[0209] In some embodiments of the present disclosure, referring to FIG5 , the fourth guide point P4 is the point at which the guide trajectory line S is at its maximum distance from the door front wall 31, and the sixth guide point Q6 is the point at which the guide trajectory line K is at its maximum distance from the door front wall 31. The angle between the straight line P4Q6, which contains the fourth guide point P4 and the sixth guide point Q6, and the door front wall 31 is denoted as a first angle σ1.

[0210] It should be noted that the line-plane angle ranges from 0° to 90°. With respect to the door front wall 31, the straight line P4Q6 can be configured to extend from its end near the door front wall 31 toward the door rear wall 33 and the door side wall 32 (as shown by the first angle σ1 in FIG5 ). Of course, the straight line P4Q6 can also be configured to extend from its end near the door front wall 31 toward the door rear wall 33 and away from the door side wall 32. The first angle σ1 is the non-obtuse angle formed between the straight line P4Q6 and the door front wall 31.

[0211] In some embodiments of the present disclosure, the first angle σ1 is any value between 85° and 90°.

[0212] In some embodiments of the present disclosure, the straight line P4Q6 where the fourth guide point P4 and the sixth guide point Q6 are located is approximately perpendicular to the door front wall 31. The first angle σ1 is any value between 89° and 90°.

[0213] In some embodiments of the present disclosure, the angle between the straight line P4Q6 where the fourth guide point P4 and the sixth guide point Q6 are located and the door sidewall 32 is recorded as a fourth angle σ4. The fourth angle σ4 is any value between 0° and 5°.

[0214] In some embodiments of the present disclosure, the straight line P4Q6 where the fourth guide point P4 and the sixth guide point Q6 are located is approximately parallel to the door side wall 32, and the fourth angle σ4 is any value between 0° and 1°.

[0215] As described above, the line-plane angle ranges from 0° to 90°. With respect to the door sidewall 32, the straight line P4Q6 can be configured to extend from its end near the door front wall 31 toward the door rear wall 33 and the door sidewall 32. Of course, the straight line P4Q6 can also be configured to extend from its end near the door front wall 31 toward the door rear wall 33 and away from the door sidewall 32. The fourth angle σ4 is a non-obtuse angle value of the angle formed between the straight line P4Q6 and the door sidewall 32.

[0216] In some embodiments of the present disclosure, the first angle σ1 between the straight line P4Q6 and the door front wall 31 and the angle between the straight line P4Q6 and the door side wall 32 are both line-plane angles, and the line-plane angle range is 0° to 90°.

[0217] As described above, the limitation of the first angle σ1 and the fourth angle σ4 further limits the relative positions of the guide trajectory line S and the guide trajectory line K whose distance from the door front wall 31 first increases and then decreases, thereby limiting the movement trend of the first axis 41 relative to the guide part 50 and the second axis 42 relative to the guide part 60 relative to the first body side wall and the pick-up and release port during the opening process of the door body 30, so that the first axis 41 and the second axis 42 have a movement trend close to the first body side wall and the pick-up and release port throughout the entire process, so that the door body 30 has a movement trend close to the second body side wall and away from the plane where the pick-up and release port is located relative to the box body 10 throughout the entire process, so as to realize the door body 30 moving inward and forward throughout the entire process.

[0218] In some embodiments of the present disclosure, the starting guide point Q0 and the eighth guide point Q8 are the opposite end points of the guide trajectory line K, respectively.

[0219] In some embodiments of the present disclosure, the starting guiding point P0 corresponds to the position of the first central axis P relative to the guiding trajectory line S when the door body 30 is closed.

[0220] In some embodiments of the present disclosure, the eighth guiding point P8 corresponds to the position of the first central axis P relative to the guiding trajectory line S when the door body 30 is opened to the eighth angle G8.

[0221] In some embodiments of the present disclosure, the starting guide point Q0 corresponds to the position of the second central axis Q relative to the guide trajectory line K when the door body 30 is closed.

[0222] In some embodiments of the present disclosure, the eighth guide point Q8 corresponds to the position of the second center axis Q relative to the guide trajectory line K when the door body 30 is opened to the eighth angle G8.

[0223] In some embodiments of the present disclosure, when designing the second hinge, in order to prevent the door body 30 from moving excessively toward the box body 10 due to excessive force when closing the door body 30, an extension section is provided at one end of the guide track line S or the guide track line K close to the door front wall 31 to reserve space for the above situation. Similarly, in order to prevent the door body 30 from being opened to the maximum angle G maxIn case that excessive force is applied and the guide door body 30 moves excessively (due to deformation or other factors), an extension section is provided at the end of the guide trajectory line S away from the door front wall 31 or at the end of the guide trajectory line K close to the door side wall 32 to reserve space for the above situation. When space is reserved at at least one of the two ends of the guide portion 50 or the guide portion 60, the starting guide point P0, the starting guide point Q0, the eighth guide point P8, and the eighth guide point Q8 are not the endpoints of their respective trajectories, that is, the setting of the starting guide point P0, the starting guide point Q0, the eighth guide point P8, and the eighth guide point Q8 as the endpoints of their respective trajectories is only an implementable method. The starting guide point P0, the starting guide point Q0, the eighth guide point P8, and the eighth guide point Q8 essentially correspond to the positions of the two hinge axes when the door body 30 is closed or opened to the maximum angle (such as the eighth angle G8), and are not restricted by the endpoints of their respective trajectories.

[0224] In some embodiments of the present disclosure, the starting guide point P0 is located on a side of the starting guide point Q0 close to the door rear wall 33 and the door side wall 32 .

[0225] In some embodiments of the present disclosure, the eighth guiding point P8 is located on a side of the starting guiding point Q0 close to the door front wall 31 and the door side wall 32 .

[0226] In some embodiments of the present disclosure, the eighth guide point Q8 is located on a side of the eighth guide point P8 close to the door rear wall 33 and the door side wall 32 .

[0227] In some embodiments of the present disclosure, as shown in Figure 3, in the normal direction (X-axis) along the door side wall 32, the distance between the starting guide point Q0 and the eighth guide point Q8 is recorded as the first lateral distance E1, and the distance between the eighth guide point P8 and the eighth guide point Q8 is recorded as the second lateral distance E2.

[0228] The first lateral distance E1 is any value between 25 mm and 30 mm.

[0229] In some embodiments of the present disclosure, the first lateral distance E1 is any value between 25 mm and 28 mm or any value between 28 mm and 30 mm.

[0230] The second lateral distance E2 is any value between 2 mm and 4 mm.

[0231] In some embodiments of the present disclosure, the second lateral distance E2 is any value between 4 mm and 6 mm.

[0232] In some embodiments of the present disclosure, the second lateral distance E2 is any value between 2 mm and 6 mm.

[0233] In some embodiments of the present disclosure, along the normal line (Y-axis) of the door front wall 31, the distance between the eighth guide point P8 and the eighth guide point Q8 along the normal line of the door front wall 31 is recorded as a first longitudinal distance D1. The distance between the sixth guide point Q6 and the eighth guide point Q8 along the normal line of the door front wall 31 is recorded as a second longitudinal distance D2. The distance between the starting guide point Q0 and the eighth guide point P8 along the normal line of the door front wall 31 is recorded as a third longitudinal distance D3.

[0234] The first longitudinal distance D1 is any value between 10 mm and 14 mm.

[0235] In some embodiments of the present disclosure, the first longitudinal distance D1 is any value between 8 mm and 10 mm.

[0236] In some embodiments of the present disclosure, the first longitudinal distance D1 is any value between 14 mm and 16 mm.

[0237] In some embodiments of the present disclosure, the first longitudinal distance D1 is any value between 8 mm and 16 mm.

[0238] In some embodiments of the present disclosure, the second longitudinal distance D2 is any value between 3 mm and 4 mm.

[0239] In some embodiments of the present disclosure, the second longitudinal distance D2 is any value between 4 mm and 6 mm.

[0240] In some embodiments of the present disclosure, the second longitudinal distance D2 is any value between 3 mm and 6 mm.

[0241] In some embodiments of the present disclosure, the third longitudinal distance D3 is any value between 0 mm and 1 mm.

[0242] In some embodiments of the present disclosure, the third longitudinal distance D3 is any value between 1 mm and 2 mm.

[0243] In some embodiments of the present disclosure, the third longitudinal distance D3 is any value between 0 mm and 2 mm.

[0244] In some embodiments of the present disclosure, the guide trajectory line S and the guide trajectory line K are confined within a rectangular frame with a horizontal length of 25mm to 30mm and a vertical length of 13mm to 18mm (or 11mm to 22mm). The outer contour dimensions of the guide portion 50 (guide groove) and the guide portion 60 (guide groove) are set according to the diameter dimensions of the first shaft 41 and the second shaft 42, and the guide portion 50 and the guide portion 60 can be confined within a rectangular frame with a horizontal length of 35mm to 40mm and a vertical length of 23mm to 28mm (or 21mm to 32mm). The above arrangement makes the arrangement of the guide portion 50 and the guide portion 60 compact and reduces the occupied area, so that the size of the door body 30 along the direction perpendicular to the door side wall 32 (X axis) can be fully utilized, and the size of the door body 30 along the direction perpendicular to the door front wall 31 (Y axis) can be reduced, thereby reducing the occupation of the thickness dimension of the door body 30 by the guide portion 50 and the guide portion 60, so that the arrangement is also applicable when the door body 30 is thinned.

[0245] In some embodiments of the present disclosure, as shown in FIG. 6 , when the door body 30 is closed, the distance (gap) between the door front wall 31 and the storage cabinet 100 is recorded as L1 .

[0246] In some embodiments of the present disclosure, L1 is any value between 2 mm and 5 mm.

[0247] In some embodiments of the present disclosure, L1 is less than or equal to 3 mm.

[0248] In some embodiments of the present disclosure, the thickness of the door body 30 along a direction perpendicular to the door front wall 31 is π.

[0249] The thickness π of the door body 30 is the distance between the door front wall 31 and the door rear wall 33 along a direction perpendicular to the door front wall 31 .

[0250] As a method for measuring the thickness of the door body 30, a measuring tape is placed on the door sidewall 32, with the measuring tape perpendicular to the door front wall 31. The distance between the intersection of the measuring tape and the extension of the door front wall 31 and the intersection of the measuring tape and the extension of the door rear wall 33 is the thickness of the door body 20.

[0251] In some embodiments of the present disclosure, L1:π is any value between 0.07 and 0.11. The above-defined relationship between the thickness of the door body 30 and the distance between the door front wall 31 and the inner wall of the storage cabinet 100 allows the door body 30 to open smoothly under the configuration of the hinge assembly of the present disclosure, and prevents the first side edge W of the door body 30 from colliding with the inner wall of the storage cabinet 100 during opening, thereby preventing the door body 30 from being unable to open.

[0252] In some embodiments of the present disclosure, the refrigerator is placed in the storage cabinet 100, and the maximum angle G that the door 30 can open is max(=G8) is greater than or equal to 115°.

[0253] 13 , when the door body 30 is opened to 90°, the door front wall 31 is located on the side of the first body side wall close to the second body side wall. The distance between the door front wall 31 and the first body side wall is recorded as L3.

[0254] In some embodiments of the present disclosure, L3 is any value between 0 mm and 5 mm.

[0255] In some embodiments of the present disclosure, π:L3 is any value between 0.07 and 0.25.

[0256] In some embodiments of the present disclosure, referring to FIG6 , a plane located on the side of the first body sidewall away from the second body sidewall and at a distance α′ from the first body sidewall (i.e., the reference plane M0) is recorded as a first reference plane M1 (refer to FIG15 ), and a plane passing through the first side edge W and parallel to the plane where the access port is located is recorded as a fourth reference plane M4. The first reference plane M1 and the fourth reference plane M4 intersect at the limiting edge line L x .

[0257] When the door body 30 closes the access opening, the door front wall 31 is flush with the fourth reference plane M4.

[0258] When the door body 30 is opened to the eighth angle G8, the door body 30 and the limiting edge line L x Wherein, G8 is greater than or equal to 115°.

[0259] When the door body 30 is opened to 90 degrees, L3 is any value between 0 mm and 5 mm.

[0260] That is, when the refrigerator is placed in the storage cabinet 100, the maximum angle G that the door 30 can open is max (=G8) is greater than or equal to 115°. Moreover, when the door body 30 is opened to 90°, the distance between the door front wall 31 and the first body side wall is less than or equal to 5 mm.

[0261] It is understood that in order to reduce the obstruction of the door 30 on the storage space (access opening), the thickness of the door 30 is as thin as possible. For built-in refrigerators, when the door 30 is opened to 90 degrees, the distance between the door front wall 31 and the first side wall of the box body 10 is as small as possible, so that the door 30 is closer to the storage cabinet 100.

[0262] However, since the guide portion 50 and the guide portion 60 are provided on the door body 30 , the small thickness of the door body 30 is not conducive to the arrangement of the guide portion 50 and the guide portion 60 .

[0263] In addition, if the distance between the door front wall 31 and the first side wall of the box body 10 is small when the door is opened at 90 degrees, it is easy to limit the opening angle of the door body 30 of the refrigerator in the storage cabinet 100, making it inconvenient for users to take and put items.

[0264] The above limitation on the maximum opening angle of the door body 30 and the distance between the door front wall 31 and the first side wall of the box body 10 when the door body 30 is opened to 90° effectively solves the contradictions among the thickness of the door body 30, the drawer pulled out and placed in the storage room when the door is opened at 90°, and the layout design of the guide part 50 and the guide part 60, while taking into account the above three requirements.

[0265] In some embodiments of the present disclosure, the box body 10 is placed in the storage cabinet 100, and the maximum angle G that the door body 30 can open is max It is between 115° and 125°.

[0266] In some embodiments of the present disclosure, when the door body 30 is closed, the door front wall 31 is flush with the end surface of the opening end of the storage cabinet 100 .

[0267] It should be noted that the above flush includes the situation where the distance between the end surface of the door front wall 31 and the open end of the storage cabinet 100 is less than 2 mm.

[0268] In some embodiments of the present disclosure, as shown in FIG6 , the distance α′ between the first sidewall of a refrigerator installed in a storage cabinet 100 and the inner wall of the storage cabinet 100 is greater than the distance between the door sidewall 32 and the inner wall of the storage cabinet 100 when the door 30 is closed, i.e., α′>L1. When the door 30 is closed, the door 30 effectively shields the refrigerator body 10, preventing the refrigerator body 10 from bulging due to foaming, which would affect its appearance.

[0269] In some embodiments of the present disclosure, referring to Figure 3, the point where the distance between the end of the guide portion 50 (guide groove) away from the door side wall 32 and the door front wall 31 is the minimum is recorded as the first guide boundary point Z1, the point where the distance between the end of the guide portion 50 (guide groove) close to the door side wall 32 and the door front wall 31 is the minimum is recorded as the second guide boundary point Z2, and the point where the distance between the guide portion 50 (guide groove) and the door front wall 31 is the maximum is recorded as the third guide boundary point Z3.

[0270] The first guide boundary point Z1, the second guide boundary point Z2, and the third guide boundary point Z3 are all located on the wall surface of the guide portion 50 (guide groove) for mating with the first shaft 41. For example, when the guide portion 50 is a guide groove, the above three guide boundary points are all located on the inner wall of the guide groove.

[0271] In some embodiments of the present disclosure, the point where the distance between the end of the guide portion 60 (guide groove) away from the door side wall 32 and the door front wall 31 is the minimum is recorded as the first guide boundary point H1, the point where the distance between the end of the guide portion 60 (guide groove) close to the door side wall 32 and the door front wall 31 is the minimum is recorded as the second guide boundary point H2, and the point where the distance between the guide portion 60 (guide groove) and the door front wall 31 is the maximum is recorded as the third guide boundary point H3.

[0272] The first guide boundary point H1, the second guide boundary point H2, and the third guide boundary point H3 are all located on the wall surface of the guide portion 60 (guide groove) for matching with the second shaft 42. For example, when the guide portion 60 is a guide groove, the above three guide boundary points are all located on the inner wall of the guide groove.

[0273] In some embodiments of the present disclosure, the first guiding boundary point Z1 is located on a side of the starting guiding point P0 close to the door front wall 31 .

[0274] In some embodiments of the present disclosure, a straight line Z1P0 between the first guiding boundary point Z1 and the starting guiding point P0 is perpendicular to the door front wall 31 .

[0275] In some embodiments of the present disclosure, the distance between the first guide boundary point Z1 and the starting positioning point P0 is equal to the radius of the first axis 41 .

[0279] In some embodiments of the present disclosure, the third guide boundary point Z3 is located on a side of the fourth guide point P4 away from the door front wall 31 .

[0280] In some embodiments of the present disclosure, the straight line Z2P4 where the third guide boundary point Z3 and the fourth guide point P4 are located is perpendicular to the door front wall 31 .

[0281] In some embodiments of the present disclosure, the distance between the third guide boundary point Z3 and the fourth guide point P4 is equal to the radius of the first axis 41 .

[0282] In some embodiments of the present disclosure, the first guide boundary point H1 is located on the side of the starting guide point Q0 close to the door front wall 31.

[0286] In some embodiments of the present disclosure, the straight line H2Q8 between the second guide boundary point H2 and the eighth guide point Q8 is perpendicular to the door front wall 31 .

[0287] In some embodiments of the present disclosure, the distance between the second guide boundary point H2 and the eighth guide point Q8 is equal to the radius of the second axis 42 .

[0288] In some embodiments of the present disclosure, the third guide boundary point H3 is located on the side of the sixth guide point Q6 away from the door front wall 31 .

[0289] In some embodiments of the present disclosure, the straight line H3Q6 where the third guide boundary point H3 and the sixth guide point Q6 are located is perpendicular to the door front wall 31 .

[0290] In some embodiments of the present disclosure, the distance between the third guide boundary point H3 and the sixth guide point Q6 is equal to the radius of the second axis 42 .

[0291] It should be noted that the distance between the first guide boundary point Z1 and the starting positioning point P0 is equal to the radius of the first axis 41, the distance between the second guide boundary point Z2 and the eighth positioning point P8 is equal to the radius of the first axis 41, the distance between the third guide boundary point Z3 and the fourth guide point P4 is equal to the radius of the first axis 41, the distance between the first guide boundary point H1 and the starting guide point Q0 is equal to the radius of the second axis 42, the distance between the second guide boundary point H2 and the eighth guide point Q8 is equal to the radius of the second axis 42, and the distance between the third guide boundary point H3 and the sixth guide point Q4 is equal to the radius of the second axis 42. The "equal" includes deviations caused by processing errors, etc.

[0292] In addition, the above “equal” includes the case where the difference between the two equal objects is any value between 0 and 2 mm.

[0293] It should be noted that, under the premise that the door front wall 31 and the door side walls 32 are arranged perpendicularly, the direction perpendicular to the door front wall 31 is the same as the direction parallel to the door side walls 32, that is, the Y-axis direction in Figure 3. The direction perpendicular to the door side walls 32 is the same as the direction parallel to the door front wall 31, that is, the X-axis direction in Figure 3.

[0294] In the case where the door front wall 31 and the door side walls 32 are not arranged perpendicularly, the direction perpendicular to the door front wall 31 only refers to the distance in the direction perpendicular to the door front wall 31 and has no necessary connection with the door side walls 32. Similarly, the direction perpendicular to the door side walls 32 only refers to the distance in the direction perpendicular to the door side walls 32 and has no necessary connection with the door front wall 31.

[0295] In the direction perpendicular to the door side wall 32, the distance between the first guide boundary point Z1 and the third guide boundary point Z3 is recorded as the first guide side spacing E' P1 The distance between the third guide boundary point Z3 and the second guide boundary point Z2 is recorded as the second guide side spacing E' P2 .

[0296] In some embodiments of the present disclosure, E' P1 :E` P2 Any value between 1.3 and 2.

When the diameters of the first shaft 41 and the second shaft 42 are determined, E' P1 :E` P2 The extension trend of the guide portion 50 is limited, thereby affecting the extension trend of the guide portion 60, ensuring that the guide portion 50 and the guide portion 60 are arranged compactly, which helps to reduce the thickness of the door body 30. In addition, when the door body 30 is opened to the maximum angle, the geometric center of the door body 30 can fall between the central axis of the first axis 41 and the central axis of the second axis 42, thereby increasing the stability of the door body 30 when it is opened to the maximum angle.

[0300] E` above P1 :E` P2 It is limited within the above range, so that the door body 30 moves inward and forward in the early stage of opening to ensure that the first shaft 41 can move to the fourth guide point P4 (inflection point) after the first shaft 41 rotates to nearly half the displacement, so that the door body 30 moves to the minimum displacement of its first side edge W from the storage cabinet 100, and then rotates inward (rotates in the direction close to the second body side wall) as the opening angle of the door body 30 increases, ensuring that the door body does not touch the storage cabinet 100 and reducing the restriction of the storage cabinet 100 on the opening angle of the door body 30.

[0602] The above guide roll angle μ` P , the first roll angle μ` PQ The definition of their relative relationship further defines the relative positions of the seventh guide point P7, the eighth guide point P8, and the seventh guide point Q7. This allows the P7P8 segment of the guide trajectory S, extending from P7 to P8, to be smoother than the straight line tangent to the guide trajectory S at point P7. Furthermore, the above definition allows the door 30 to maintain greater inward and forward movement efficiency when further opening from 90°, thereby reducing the impact of the storage cabinet 100 on the door 30.

[0606] In some embodiments of the present disclosure, the first shaft 41 moves relative to the guide portion 50 first toward a side away from the door front wall 31 and close to the door side wall 32 , and then moves toward a side close to the door front wall 31 and the door side wall 32 .

[0607] In some embodiments of the present disclosure, the second shaft 42 moves relative to the guide portion 60 first toward a side away from the door front wall 31 and close to the door side wall 32, and then moves toward a side close to the door front wall 31 and the door side wall 32.

[0608] The first shaft 41 moves relative to the guide portion 50 and the second shaft 42 moves relative to the guide portion 60, so that the door body 30 can move a certain distance inward (toward the side wall of the second body) while rotating, so as to compensate for the distance that the first side edge W moves outward caused by the simple rotational movement of the door body 30, thereby controlling the distance that the first side edge W exceeds the side wall of the first body, so as to limit the distance that the first side edge W exceeds the side wall of the first body to within the range of the gap between the storage cabinet 100 and the side wall of the first body, thereby avoiding the first side edge W colliding with the storage cabinet 100 and causing the door body 30 to be unable to open.

[0609] In some embodiments of the present disclosure, the distance between the first central axis P and the door front wall 31 when the door body 30 is in a closed state is equal to the distance between the first central axis P and the door front wall 31 when the door body 30 is opened to 90 degrees.

[0610] In some embodiments of the present disclosure, the distance between the starting guiding point P0 on the guiding trajectory line S and the door front wall 31 is equal to the distance between the seventh guiding point P7 and the door front wall 31 .

[0611] In some embodiments of the present disclosure, the straight line P0P7 between the starting guiding point P0 and the seventh guiding point P7 on the guiding trajectory line S is parallel to the door front wall 31 .

[0612] In some embodiments of the present disclosure, when the door body 30 is in a closed state, the straight line P0P7 between the starting guide point P0 and the seventh guide point P7 on the guide trajectory line S is parallel to the plane where the access port is located.

[0613] In some embodiments of the present disclosure, when the door body 30 is in a closed state, a straight line P0P7 between the starting guiding point P0 and the seventh guiding point P7 on the guiding trajectory line S is perpendicular to the side wall of the first body.

[0614] Since the guide portion 50 and the first shaft 41, as well as the guide portion 60 and the second shaft 42, are in relative motion, if the door body 30 is opened, with the guide portion 50 and the guide portion 60 as stationary reference objects, it is equivalent to the first shaft 41 moving under the restriction of the guide portion 50, and the second shaft 42 moving under the restriction of the guide portion 60. For the sake of convenience in description, the present disclosure uses the guide portion 50 and the guide portion 60 as stationary reference objects, and the first shaft 41 and the second shaft 42 move relative to the reference objects.

[0615] In some embodiments of the present disclosure, within the projection of the plane where the top wall of the box body 10 is located, the line segment PQ is recorded as the axis line segment PQ. The center of the axis line segment PQ is recorded as the axis center point I. As shown in Figures 6 to 24, the movement of the first shaft 41 along the guide portion 50 is equivalent to the movement of the first center axis P along the guide trajectory line S, and the movement of the second shaft 42 along the guide portion 60 is equivalent to the movement of the second center axis Q along the guide trajectory line K, so that the door body 30 can move a certain distance inward (toward the side wall of the second body) while rotating, so that the door body 30 does not interfere with the storage cabinet 100, ensuring that the door body 30 is effectively opened.

[0616] The movement of the door body 30 relative to the box body 10 is equivalent to the relative movement of the two within the plane where the top wall of the box body 10 is located (or within a plane parallel to the top wall of the box body 10). That is, the movement of the door body 30 relative to the box body 10 can be attributed to relative movement within a two-dimensional plane. Since the first hinge member having the first axis 41 and the second axis 42 is fixed to the box body 10, and the second hinge member having the guide portion 50 and the guide portion 60 is located on the door body 30, the movement of the first hinge member (axial line segment PQ) relative to the door body 30 (guide portion 50 and guide portion 60) within the plane where the top wall of the box body 10 is located is equivalent to the movement of the axial line segment PQ relative to the door body 30, and is also equivalent to the movement of the box body 10 relative to the door body 30.

[0617] In the following description, for ease of illustration, the movement of the axis line segment PQ relative to the second hinge member (guide portion 50 and guide portion 60) provided on the door body 30 within the plane of the top wall of the box body 10 is selected to represent the movement of the box body 10 relative to the door body 30.

The second shaft 42 is located on a side of the first shaft 41 that is close to the door front wall 31 and away from the door side wall 32.

[0620] In some embodiments of the present disclosure, when the door body 30 is closed, the first axis 41 and the second axis 42 are both close to the door front wall 31 relative to the door rear wall 33. That is, when the door body 30 is closed, the first axis 41 and the second axis 42 are both located on the side of the middle plane C close to the door front wall 31.

Furthermore, while ensuring that the maximum angle at which the door 30 of a refrigerator placed in the storage cabinet 100 can be opened is sufficiently large, this arrangement also minimizes obstruction of the access opening by the door 30 when opened to 90°.

Specifically, the first shaft 41 maintains unidirectional movement without reversing direction, ensuring that the force acting on the first shaft 41 remains consistent during the opening of the door 30. This improves the service life of the guide portion 50. Furthermore, the first shaft 41 maintains unidirectional movement throughout the entire process of opening the door 30, eliminating the need for acceleration during stopping and restarting, further enhancing the smoothness of the movement of the first shaft 41.

In other words, the second shaft 42 maintains unidirectional movement without reversing direction, ensuring that the force acting on the second shaft 42 remains consistent during the opening of the door 30. This improves the service life of the guide portion 60. Furthermore, the second shaft 42 maintains unidirectional movement throughout the entire process of opening the door 30, eliminating the need for acceleration during the entire opening process. This also improves the smoothness of the movement of the second shaft 42.

[0663] In some embodiments of the present disclosure, the first shaft 41 and the second shaft 42 maintain unidirectional movement throughout the entire process of the door body 30 opening, without reversing direction. This ensures that the force directions of the first shaft 41 and the second shaft 42 remain consistent during the process of the door body 30 opening, thereby improving the service life of the guide portion 50 and the guide portion 60. Furthermore, the first shaft 41 and the second shaft 42 maintain unidirectional movement throughout the entire process of the door body 30 opening, thereby eliminating the acceleration of the door body 30 stopping and moving again during the entire opening process, thereby improving the smoothness of the movement of the door body 30.

[0665] Combined with the positions of the two limiting axes (the first axis 41 and the second axis 42) relative to the limiting parts (the guide part 50 and the guide part 60) when the door body 30 is opened to a specific angle, it can be seen that the matching relationship between the first axis 41 and the guide part 50 exists as follows.

[0666] When the door body 30 opens from the closed state to G4, the first shaft 41 moves along the guide portion 50 toward the door rear wall 33 and the door side wall 32, and the second shaft 42 moves along the guide portion 60 toward the door side wall 32 and the door rear wall 33.

[0689] 6 to 14 , refer to FIG. 16 . hereinafter, the relative movement of the two stages will be described from the perspective of the matching relationship between the first shaft 41 and the guide portion 50 and the second shaft 42 and the guide portion 60 .

[0690] (1) The first stage, as shown in FIG. 6 to FIG. 10 and FIG. 16 to FIG. 20 , is a process in which the door body 30 rotates from the closed state to open to G4.

[0691] In this first stage, the door body 30 opens from 0° through G1, G2, G3 to G4. During this process, the first central axis P moves from the starting guide point P0 along the guide trajectory S toward the door rear wall 33 and the door side walls 32. The second central axis Q moves from the starting guide point Q0 along the guide trajectory K toward the door rear wall 33 and the door side walls 32.

[0692] For example, the first central axis P moves from the starting guide point P0 along the guide trajectory S, sequentially passing through the first guide point P1, the second guide point P2, the third guide point P3, and finally to the fourth guide point P4. The second central axis Q moves from the starting guide point Q0 along the guide trajectory K, sequentially passing through the first guide point Q1, the second guide point Q2, the third guide point Q3, and finally to the fourth guide point Q4.

[0693] The first stage of opening process is described with reference to the second hinge member (the guide portion 50 / the guide portion 60 / the door body 30 ).

[0694] As the door 30 opens from 0° to G4, the axis line segment PQ rotates clockwise from P0Q0 and moves toward the door sidewalls 32 and rear wall 33, successively to P1Q1, P2Q2, P3Q3, and P4Q4. That is, the movement trend of the axis line segment PQ is P0Q0 → P1Q1 → P2Q2 → P3Q3 → P4Q4. Simultaneously, the movement trend of the axis center point I as the axis line segment PQ moves is I0 → I1 → I2 → I3 → I4. That is, as the door 30 opens, the axis center point I moves toward the door sidewalls 32 and rear wall 33 relative to the door body 30.

[0695] Since the guiding portion 50 and the guiding portion 60 are arranged on the door body 30, the axial line segment PQ represents the movement of the hinge plate 40 arranged on the box body 10. Therefore, it can be concluded that: taking the door body 30 as a reference, during the entire process of the door body 30 opening from the closed state to the fourth angle G4, the box body 10 (i.e., the hinge plate 40) keeps rotating clockwise relative to the door body 30 to open, and moves a preset distance toward the direction close to the door side wall 32 and the door rear wall 33.

[0696] In summary, when the door body 30 is opened from the closed state to the fourth angle G4, with the door body 30 (guide groove / guide slot) as a reference, the box body 10 performs a rotational motion relative to the door body 30 and simultaneously undergoes a translational motion. This translational motion may be, for example, a displacement of the box body 10 relative to the door body 30 parallel to the door rear wall 33 and toward the door side wall 32, and a displacement parallel to the door side wall 32 and away from the door front wall 31.

[0697] According to the relativity of motion, with the cabinet 10 as a reference, when the door 30 is opened from the closed state to the fourth angle G4, the door 30 undergoes both rotational motion and translational motion. This translational motion may be, for example, displacement of the door 30 relative to the cabinet 10 parallel to the door rear wall 33 and directed away from the door side walls 32, and displacement parallel to the door side walls 32 and directed toward the door front wall 31.

[0698] In some embodiments of the present disclosure, the first stage can be divided into a first segment and a second segment by combining the guide trajectory line S to set a straight first guide line and a curved second guide line.

[0699] For example, in the first segment, the door body 30 is opened from the closed state to the second angle G2, and the first central axis P moves linearly from the starting guide point P0 along the guide trajectory S toward the door rear wall 33 and the door side wall 32. The second central axis Q moves curvedly from the starting guide point Q0 along the guide trajectory K toward the door rear wall 33 and the door side wall 32.

[0700] In the second section, the door body 30 opens from the second angle G2 to the fourth angle G4, and the first central axis P moves in a curved line from the starting guide point P0 along the guide trajectory S toward the door rear wall 33 and the door side wall 32. The second central axis Q moves in a curved line from the starting guide point Q0 along the guide trajectory K toward the door rear wall 33 and the door side wall 32.

[0701] The relative movement between the first segment and the second segment is the same as the process in which the door body 30 is opened from the closed state to the fourth angle G4, and will not be described in detail here.

[0702] (2) The second stage, in combination with Figures 10 to 12 , as shown in Figures 20 to 22 , 25 and 26 , is a process in which the door body 30 rotates and opens from G4 to G6 .

[0703] In this second stage, the door body 30 opens from G4 to G5 and then to G6. During this process, the first central axis P moves from the fourth guide point P4 along the guide trajectory S toward the door front wall 31 and the door side walls 32. The second central axis Q moves from the fourth guide point Q4 along the guide trajectory K toward the door rear wall 33 and the door side walls 32.

[0704] For example, the first central axis P moves from the fourth guide point P4 along the guide trajectory S through the fifth guide point P5 to the sixth guide point P6. The second central axis Q moves from the fourth guide point Q4 along the guide trajectory K through the fifth guide point Q5 to the sixth guide point Q6.

[0705] The second stage of opening process is described with reference to the second hinge member (the guide portion 50 / the guide portion 60 / the door body 30 ).

[0706] As the door 30 opens from G4 to G6, the axis segment PQ rotates clockwise from P4Q4 and moves toward the door sidewall 32 to P5Q5 and P6Q6, respectively. This means the axis segment PQ moves from P4Q4 to P5Q5 and then to P6Q6. Simultaneously, the axis center point I moves from I4 to I5 to I6 as the axis segment PQ moves.

[0707] In some embodiments of the present disclosure, when the door body 30 is opened to the reversing angle G', the axis center point I moves to the reversing midpoint I'. At this time, the distance between the axis center point I and the door front wall 31 is the largest.

[0708] In some embodiments of the present disclosure, G4<G5<G`<G6. That is, before the second central axis Q moves to the sixth guide point Q6, where the guide trajectory line K is at the greatest distance from the door front wall 31, the guide center I has already moved to the position at the greatest distance from the door front wall 31.

[0709] That is, when the door body 30 rotates from the fourth angle G4 to the sixth angle G6, the axis center point I first moves toward the door side walls 32 and the door rear wall 33, and then moves toward the door side walls 32 and the door front wall 31. During the opening process of the door body 30, the movement trend of the axis center point I along the axis line segment PQ is I4 → I5 → I` → I6.

[0710] Since the guide portion 50 and the guide portion 60 are provided on the door body 30, and the axis line segment PQ represents the movement of the hinge plate 40 provided on the box body 10, it can be concluded that: with the door body 30 as a reference, during the process of the door body 30 opening from the fourth angle G4 to the reversing angle G', the box body 10 (i.e., the hinge plate 40) continues to rotate clockwise relative to the door body 30 to open, and moves a predetermined distance toward the door sidewall 32 and the door rear wall 33. Furthermore, during the process of the door body 30 opening from the reversing angle G' to the sixth angle G6, the box body 10 (i.e., the hinge plate 40) continues to rotate clockwise relative to the door body 30 to open, and moves a predetermined distance toward the door sidewall 32 and away from the door rear wall 33.

[0711] In summary, when the door body 30 opens from the fourth angle G4 to the reversing angle G', with the door body 30 (guide groove / guide slot) as a reference, the box body 10 performs a rotational motion relative to the door body 30 and simultaneously undergoes a translational motion. This translational motion may be, for example, a displacement of the box body 10 relative to the door body 30 parallel to the door rear wall 33 and toward the door side wall 32, and a displacement parallel to the door side wall 32 and away from the door front wall 31.

[0712] During the process of the door body 30 opening from the reversing angle G' to the sixth angle G6, with the door body 30 (guide groove / guide slot) as a reference, the box body 10 performs a rotational motion relative to the door body 30 and simultaneously undergoes a translational motion. This translational motion may include, for example, a displacement of the box body 10 relative to the door body 30 parallel to the door rear wall 33 and toward the door side wall 32, and a displacement parallel to the door side wall 32 and toward the door front wall 31.

[0713] Due to the relative nature of motion, with the cabinet 10 as a reference, during the process of the door 30 opening from the fourth angle G4 to the reversing angle G', the door 30 undergoes simultaneous translational motion while undergoing rotational motion. This translational motion may include, for example, displacement of the door 30 relative to the cabinet 10 parallel to the door rear wall 33 and directed away from the door side walls 32, and displacement parallel to the door side walls 32 and directed toward the door front wall 31.

[0714] In the process of the door body 30 opening from the reversing angle G' to the sixth angle G6, the door body 30 has a displacement relative to the box body 10 that is parallel to the door rear wall 33 and points to the side away from the door side wall 32, and a displacement that is parallel to the door side wall 32 and points to the side away from the door front wall 31.

[0715] In some embodiments of the present disclosure, G'=G6. That is, when the door body 30 opens to the reversing angle G', the second center axis Q moves to the sixth guide point Q6 on the guide trajectory line K, which is the closest to the door front wall 31. During the process of the door body 30 opening from G4 to G6, the center point I of the axis moves toward the door side walls 32 and the door rear wall 33 relative to the door body 30. For the specific movement of the door body 30, please refer to the above description of the movement of the center point I of the axis toward the door side walls 32 and the door rear wall 33 relative to the door body 30, which will not be repeated here.

[0716] (3) In the third stage, as shown in FIG. 12 to FIG. 14 , FIG. 22 to FIG. 24 and FIG. 27 , the door body 30 is rotated open from G6 to G max process.

[0717] Door 30 opens from G6 to G max During the opening process, the first central axis P moves from the sixth guide point P6 along the guide trajectory S toward the door front wall 31 and the door side wall 32. The second central axis Q moves from the sixth guide point Q6 along the guide trajectory K toward the door front wall 31 and the door side wall 32.

[0718] For example, the first central axis P moves from the sixth guide point P6 to the eighth guide point P8 along the guide trajectory S through the seventh guide point P7. The second central axis Q moves from the sixth guide point Q6 to the eighth guide point Q8 along the guide trajectory K through the seventh guide point Q7.

[0719] The opening process in the third stage is described with reference to the second hinge member (the guide portion 50 / the guide portion 60 / the door body 30 ).

[0720] Door 30 opens from G6 to G max During the process, the axis line segment PQ rotates clockwise from P6Q6 and moves to P7Q7 and P8Q8 in the direction close to the door side wall 32 and the door front wall 31. That is, the movement trend of the axis line segment PQ is P6Q6→P7Q7→P8Q8. At the same time, the movement trend of the axis center point I as the axis line segment PQ moves is I6→I7→I8. Among them, the door body 30 is opened from G6 to G max During the process, relative to the door body 30, the center point I of the axis moves toward the door side wall 32 and the door front wall 31.

[0721] In some embodiments of the present disclosure, since the guide portion 50 and the guide portion 60 are provided on the door body 30, the axis line segment PQ represents the movement of the hinge plate 40 provided on the box body 10. Therefore, it is concluded that: with the door body 30 as a reference, the door body 30 is opened from the sixth angle G6 to the maximum angle G max During the process of (eighth angle G8), the box body 10 (ie, the hinge plate 40) keeps rotating clockwise relative to the door body 30 to open, and moves a preset distance toward the door side wall 32 and the door front wall 31.

[0722] In summary, the door body 30 opens from the sixth angle G6 to the maximum angle G max During the eighth angle G8, with the door body 30 (guide groove / guide slot) as a reference, the box body 10 performs a rotational motion relative to the door body 30 and simultaneously undergoes a translational motion. This translational motion includes, for example, displacement of the box body 10 relative to the door body 30 parallel to the door rear wall 33 and toward the door side wall 32, and displacement parallel to the door side wall 32 and toward the door front wall 31.

[0723] According to the relativity of movement, with the box 10 as a reference, the door 30 opens from the sixth angle G6 to the maximum angle G max During the eighth angle G8, the door body 30 undergoes a translational motion while rotating. This translational motion includes, for example, displacement of the door body 30 relative to the housing 10 parallel to the door rear wall 33 and pointing away from the door side wall 32, and displacement parallel to the door side wall 32 and pointing away from the door front wall 31.

[0724] Combining the first, second, and third stages, we can see that: based on the relativity of motion, with the box 10 as a reference, the door body 30 has a translational motion while rotating. The translational displacement component of this translational motion includes a displacement component parallel to the door rear wall 33 and a displacement component parallel to the door side wall 32. Among them, the displacement component parallel to the door rear wall 33 is recorded as the first direction displacement. The displacement component parallel to the door side wall 32 is the second displacement direction At different opening stages of the door body 30, the first direction displacement and the second direction displacement The direction will be different.

[0725] In the first stage (the door 30 is opened from the closed state to G4) and in the second stage (the door 30 is opened from G4 to G'), the first direction displacement Pointing away from the door side wall 32, the second direction displacement Pointing to the side of the door front wall 31.

[0726] In the second stage above, the door body 30 is opened from G' to G6 and in the third stage (the door body 30 is opened from the sixth angle G6 to the maximum angle G max (eighth angle G8) process), the first direction displacement Pointing away from the door side wall 32, the second direction displacement Pointing to the side away from the front door wall 31.

[0727] That is, during the process of the door body 30 opening from the closed state to the reversing angle G', the first direction displacement Pointing away from the door side wall 32, the second direction displacement Pointing to the side of the door front wall 31.

[0728] The door body 30 opens from the reversing angle G' to the maximum angle G max During the process of (eighth angle G8), the first direction displacement Pointing away from the door side wall 32, the second direction displacement It points to the side away from the door front wall 31. The reversing angle G' is less than 90 degrees.

[0729] It should be additionally explained that “directed toward the door side wall 32 ” refers to the direction from the end of the door body 30 opposite to the door side wall 32 toward the door side wall 32 .

[0730] “Directed away from the door sidewall 32 ” refers to a direction from the door sidewall 32 toward the end of the door body 30 opposite to the door sidewall 32 .

[0731] “Toward the side of the door front wall 31 ” refers to the direction from the door rear wall 33 toward the door front wall 31 .

[0732] “Directed to the side away from the door front wall 31 ” refers to the direction from the door front wall 31 to the door rear wall 33 .

[0733] In addition, it should be noted that the first direction displacement Second direction displacement All of them are instantaneous relative translation displacements, which are used to illustrate the instantaneous translation movement trend relative to the box body 10 and the door body 30.

[0734] As shown in Figures 28 to 32, a displacement coordinate system AOB is established on the side of the box body 10 close to the door body 30 within the plane where the top wall of the box body 10 is located. For example, in the displacement coordinate system AOB, OB is perpendicular to the plane where the access port is located, and OA is parallel to the plane where the access port is located. In the displacement coordinate system AOB, the direction from the second body side wall to the first body side wall is defined as positive, and the direction from the access port to the door front wall 31 when the door body 30 is closed (from back to front) is defined as positive. It should be noted that during the opening process of the door body 30, the displacement coordinate system AOB remains stationary relative to the box body 10 and does not move with the opening of the door body 30. During the opening process of the door body 30, the relative position of the door body coordinate system X1O1Y1 relative to the displacement coordinate system AOB changes continuously with the different opening angles of the door body 30. When the opening angle of the door body 30 is determined, the instantaneous relative position of the door body coordinate system X1O1Y1 relative to the displacement coordinate system AOB remains relatively stationary.

[0735] In some embodiments of the present disclosure, in the displacement coordinate system AOB, the door body 30 has a first direction displacement parallel to the door rear wall 33. and a second direction displacement parallel to the door side wall 32 First direction displacement The displacement on the A axis is The displacement on the B axis is Second direction displacement The displacement on the A axis is The displacement on the B axis is During the whole process of the door 30 being opened,

[0736] The door body 30 opens from the closed state to the maximum angle G max During the whole process of (eighth angle G8), in the displacement coordinate system AOB, the door body 30 has a first translation displacement and the second translation displacement Relative to the box body 10, the door body 30 has a tendency to move in the negative direction along the A axis and in the positive direction toward the B axis while rotating. That is, the door body 30 opens from the closed state to the maximum angle G max During the entire process (the eighth angle G8), the door body 30 rotates and opens relative to the box body 10 while having a movement tendency of moving inward and forward.

[0737] (1) As shown in Figures 28 to 31, during the process of the door body 30 opening from the closed state to 90 degrees, as the door body 30 rotates counterclockwise relative to the box body 10, the door side walls 32, the door rear wall 33, and the door front wall 31 also rotate counterclockwise during this stage of the opening process. Within the plane of the top wall of the box body 10, the door side walls 32 extend outward and forward along the direction from the second side edge N to the first side edge W (the door rear wall 33 to the door front wall 31). The door rear wall 33 extends inward and forward along the direction from the door side walls 32 to the end of the door body 30 opposite to the door side walls 32.

[0738] During the above opening process (opening from the closed position to 90°), the door sidewall 32 begins to rotate counterclockwise from a position parallel to the reference plane M0. The angle between the door sidewall 32 and the plane containing the access opening gradually decreases, while the angle between the door sidewall 32 and the reference plane M0 gradually increases. That is, as the door 30 opens from the closed position to 90°, the door sidewall 32 extends away from the second sidewall and the access opening relative to the box body 10, along the direction from the second side edge N to the first side edge W. Simultaneously, as the opening angle of the door 30 increases, the angle between the door rear wall 33 and the plane containing the access opening gradually increases, while the angle between the door rear wall 33 and the reference plane M0 gradually decreases. That is, as the door 30 opens from the closed position to 90°, the door rear wall 33 extends away from the first sidewall and the access opening (closer to the second sidewall and away from the access opening) relative to the box body 10, along the direction from the door sidewall 32 to the end of the door 30 opposite the door sidewall 32.

[0739] (1.1) In combination with the description of the displacement direction of the door body 30 relative to the box body 10 during the process of the door body 30 opening from the closed state to the reversing angle G' (G' < 90°), it can be seen that: during the process of the door body 30 opening from the closed state to the reversing angle G', with the box body 10 as a reference, the door body 30 has a first direction displacement parallel to the door rear wall 33 and pointing to the side away from the door side wall 32. and a second direction displacement parallel to the door side wall 32 and pointing to the side of the door front wall 31 The first direction displacement Pointing to the inner front side of the box 10 (inward and forward side), the second direction displacement It points to the outer front side of the box body 10 (the side facing outward and forward).

[0740] As shown in FIG28 and FIG29, in the displacement coordinate system AOB, when the door body 30 is opened from the closed state to the reversing angle G' (G' < 90 degrees), the first direction displacement of the door body 30 is Located in the second quadrant (A<0, B>0), displacement in the second direction Located in the first quadrant (A>0, B>0). Displacement in the first direction and the second direction displacement Displacement decomposition is performed on the A-axis and B-axis respectively. Displacement in the first direction The displacement on the A axis is The displacement on the B axis is Second direction displacement The displacement on the A axis is The displacement on the B axis is Among them, the trajectory feature settings of this disclosure are Then there is, That is, when the door body 30 is opened from the closed state to the reversing angle G', in the displacement coordinate system AOB, the door body 30 has a first translation displacement and the second translation displacement Therefore, it can be concluded that, relative to the housing 10, the door body 30 has a tendency to move inward and forward translationally while rotating along the negative direction of the A axis and moving inward and forward translationally toward the positive direction of the B axis. That is, when the door body 30 opens from the closed state to the angle G' (G' < 90°), the door body 30 has a tendency to move inward and forward translationally while rotating and opening relative to the housing 10.

[0741] As described above, during the process of the door body 30 opening from the closed state to G' (G'<90°), the door body 30 keeps moving inward to compensate for the outward displacement of the first side edge W caused by the simple rotation of the door body 30, thereby limiting the distance that the first side edge W exceeds the reference plane M0, effectively preventing the door body 30 from being unable to continue opening due to interference between the first side edge W and the storage cabinet 100 when the door body 30 is opened. At the same time, the door body 30 keeps moving forward to compensate for the backward displacement of the second side edge N caused by the simple rotation of the door body 30, thereby limiting the distance that the second side edge W approaches the plane where the access port is located, thereby reducing the amount of compression on the door seal 5 when the door body 30 is opened.

[0742] (1.2) In combination with the above description of the displacement direction of the door body 30 relative to the box body 10 during the process of the door body 30 opening from the reversing angle G' to G7 = 90° (G' < G7 = 90°), it can be seen that: during the process of the door body 30 opening from the reversing angle G' to G7 = 90°, with the box body 10 as a reference, the door body 30 has a first direction displacement parallel to the door rear wall 33 and pointing to the side away from the door side wall 32. A second direction parallel to the door side wall 32 and pointing away from the door front wall 31 The first direction displacement Pointing to the inner front side of the box 10 (inward and forward side), the second direction displacement It points to the inner rear side of the box body 10 (inward and rearward side).

[0743] As shown in FIG28 and FIG30, in the displacement coordinate system AOB, during the process of the door body 30 opening from the reversing angle G' to G7 = 90°, the first direction displacement of the door body 30 is Located in the second quadrant (A<0, B>0), displacement in the second direction Located in the third quadrant (A<0, B<0). Displacement in the first direction and the second direction displacement Displacement decomposition is performed on the A-axis and B-axis respectively. Displacement in the first direction The displacement on the A axis is The displacement on the B axis is Second direction displacement The displacement on the A axis is The displacement on the B axis is Among them, the trajectory feature settings of this disclosure are Then there is, That is, when the door body 30 is opened from the reversing angle G' to G7 = 90°, in the displacement coordinate system AOB, the door body 30 has a first translation displacement and the second translation displacement Therefore, it can be concluded that, relative to the housing 10, the door body 30 has a tendency to move inward and forward translationally while rotating along the negative direction of the A axis and moving in the positive direction of the B axis. That is, during the process of the door body 30 opening from the reversing angle G' to G7 = 90°, the door body 30 has a tendency to move inward and forward translationally while rotating and opening relative to the housing 10.

[0744] (2) As shown in FIG9 , when the door body 30 is opened to 90°, the door side wall 32 is parallel to the plane of the access opening and perpendicular to the reference plane M0. At this time, the door rear wall 33 is parallel to the reference plane M0 and perpendicular to the plane of the access opening. That is, relative to the box body 10, along the direction from the second side edge N to the first side edge W, the door side wall 32 extends from the inside to the outside, and the door rear wall 33 extends from the back to the front.

[0745] Combined with the description of the displacement direction of the door body 30 relative to the box body 10 during the opening process of the door body 30, it can be concluded that when the door body 30 is opened to 90 degrees, with the box body 10 as a reference, the door body 30 has a first direction displacement parallel to the door rear wall 33 and pointing away from the door side wall 32. and a second direction displacement parallel to the door side wall 32 and pointing away from the door front wall 31 The first direction displacement Pointing to the front side of the box 10, the second direction displacement Pointing to the inside of the box 10.

[0746] As shown in FIG31 , when the door body 30 is opened to 90°, in the displacement coordinate system AOB, the first direction displacement of the door body 30 is Along the B axis and pointing to the positive direction of the B axis, the second direction displacement Along the A axis and pointing to the negative direction of the A axis. Displacement in the first direction and the second direction displacement Displacement decomposition is performed on the A-axis and B-axis respectively. Displacement in the first direction The displacement on the A axis is The displacement on the B axis is Second direction displacement The displacement on the A axis is The displacement on the B axis is in, That is, when the door body 30 is opened to 90°, in the displacement coordinate system AOB, the door body 30 has a first translation displacement and the second translation displacement Therefore, it can be concluded that, relative to the box body 10, the door body 30 has a tendency to move inward and forward translationally while rotating along the negative direction of the A axis and moving inward and forward translationally toward the positive direction of the B axis. That is, when the door body 30 is opened at 90 degrees, the door body 30 has a tendency to move inward and forward translationally while rotating and opening relative to the box body 10.

[0747] In summary, during the process of the door body 30 opening from the closed state to 90°, the door body 30 maintains a movement trend of moving inward and forward while rotating and opening.

[0748] In some embodiments of the present disclosure, the door body 30 maintains an inward translational movement tendency during the process of opening from a closed state to 90 degrees, so that when the door body 30 is opened to 90 degrees, the door front wall 31 is parallel to the first body side wall, or the door front wall 31 is located on the side of the first body side wall close to the second body side wall. In this way, when the door body 30 is opened to 90 degrees, the distance between the door body 30 (door front wall 31) and the storage cabinet 100 (reference plane M0) is increased, thereby increasing the space allowed for the door body 30 to continue opening, thereby increasing the maximum opening angle G of the door body 30 placed in the storage cabinet 100. max (eighth angle G8), reducing the restriction of the storage cabinet 100 on the opening angle of the door body 30 placed therein.

[0749] (3) As shown in Figures 9 to 12, when the door body 30 rotates from 90° to G8 (G8>90°), the door sidewall 32 also rotates counterclockwise during the opening process at this stage. Within the plane of the top wall of the box body 10, the door sidewall 32 extends outward and rearward along the direction from the second side edge N to the first side edge W. The door rear wall 33 extends outward and forward along the direction from the door sidewall 32 to the end of the door body 30 opposite the door sidewall 32.

[0750] During the above opening process, the door side wall 32 starts to rotate counterclockwise from a state perpendicular to the reference plane M0 (when the door body 30 is opened 90°), and the angle between the door side wall 32 and the plane where the access port is located gradually increases, and the angle between the door side wall 32 and the reference plane M0 gradually decreases. That is, in the process of the door body 30 rotating and opening from 90° to G8, relative to the box body 10, the door side wall 32 extends in the direction from the second side edge N to the first side edge W, and in the direction away from the second body side wall and close to the access port. At the same time, the angle between the door rear wall 33 and the plane where the access port is located gradually decreases, and the angle between the door rear wall 33 and the reference plane M0 gradually increases. That is, in the process of the door body 30 rotating and opening from 90° to G8, relative to the box body 10, the door side wall 32 extends in the direction from the door side wall 32 to the end of the door body 30 opposite to the door side wall 32, and in the direction away from the second body side wall and the access port.

[0751] When the door body 30 is rotated from 90° to G8 (G8>90°), with the box body 10 as a reference, the door body 30 has a first direction displacement parallel to the door rear wall 33 and pointing away from the door side wall 32. A second direction parallel to the door side wall 32 and pointing away from the door front wall 31 The first direction displacement Pointing to the outer front side of the box 10 (outward and forward side), the second direction displacement It points to the inner front side of the box body 10 (the side facing inward and forward).

[0752] As shown in FIG37 and FIG42, in the displacement coordinate system AOB, when the door body 30 is opened from 90° to G8 (G8>90°), the first direction displacement of the door body 30 is Located in the first quadrant (A>0, B>0), displacement in the second direction Located in the second quadrant (A<0,B>0). Displacement in the first direction and the second direction displacement Displacement decomposition is performed on the A-axis and B-axis respectively. Displacement in the first direction The displacement on the A axis is The displacement on the B axis is Second direction displacement The displacement on the A axis is The displacement on the B axis is Among them, the trajectory feature settings of this disclosure are Then there is, That is, when the door body 30 moves from 90° to G8, in the displacement coordinate system AOB, the door body 30 has a first translation displacement and the second translation displacement Therefore, it can be concluded that, relative to the housing 10, the door body 30 has a tendency to move inward and forward translationally while rotating along the negative direction of the A axis and moving inward and forward translationally toward the B axis. That is, when the door body 30 opens from 90° to G8, it has a tendency to move inward and forward translationally while rotating relative to the housing 10.

[0753] In summary, during the entire process of the door body 30 opening from the closed state to G8 (G8>90°), the door body 30 has a movement tendency of moving inward and forward while simply rotating relative to the box body 10.

[0754] Although the current double-axis and double-slot matching structure can prevent the door body 30 from colliding with the storage cabinet 100 when opening, the door body 30 cannot be fully opened in the setting scenario where the gap between the refrigerator (door body 30) and the storage cabinet is less than or equal to 3mm, which makes it inconvenient for users to take and put items.

[0755] Referring to Figures 33 and 34 , in a series of applications filed by the applicant on December 23, 2021, represented by CN115682517A, the guide trajectory of the hinge assembly's guide portion extends from its end distal to the door sidewall, first in a direction away from the door front wall and toward the door sidewall, and then in a direction toward the door front wall and the door sidewall. The guide trajectory of the guide portion extends from its end distal to the door sidewall, first in a direction away from the door front wall and toward the door sidewall, and then in a direction toward the door front wall and the door sidewall. In the projection of the plane on which the top wall of the housing is located, the midpoint of the line segment containing the central axis of the first axis and the central axis of the second axis is denoted as the axis center T. During the door opening process, the axis center T moves relative to the door body. The axis center trajectory formed by the movement of the axis center T relative to the door body first increases and then decreases as the door opening angle increases. The point at which the axis center T is at its maximum distance from the door front wall is T', and the angle of the door opening relative to the housing at this point is denoted as G'. Limited by CN115682517A, the guide trajectory line is a standard arc, and the guide trajectory line is formed by the structural limitation of two standard arcs. When the midpoint T of the axis moves relative to the door body to the point T' with the maximum distance from the front wall of the door, the opening angle of the door body relative to the box body is an obtuse angle; that is, G'>90°.

[0756] In the solution defined in CN115682517A, in the displacement coordinate system AOB, the door body has a first direction displacement parallel to the door rear wall 33. The second direction displacement parallel to the door side wall 32 First direction displacement The displacement on the A axis is The displacement on the B axis is Second direction displacement The displacement on the A axis is The displacement on the B axis is

[0757] 34 , during the process of the door body opening from 0° to 90°, as shown in (a) and (b) of FIG. 34 ,

[0758] When the door is opened to 90°, as shown in (c) in Figure 34,

[0759] When the door is opened from 90° to G', as shown in (d) in Figure 34,

[0760] The door opens from G` to the maximum angle G max During the process of (eighth angle G8), as shown in FIG34(e),

[0761] In summary, in the series of applications represented by CN115682517A, when the door body is opened from the closed state to 90°, the door body has a tendency to move inward and forward while rotating. When the door body is opened from 90° to G', the door body has a tendency to move outward and forward while rotating. max During the process of rotating (the eighth angle G8), the door body has a tendency to move inward and forward while rotating. That is, during the entire process of the door body opening, there is at least one stage in which the door body continues to move outward. This causes the angle of the refrigerator door rotating in the storage cabinet to decrease from 90 degrees, thereby reducing the maximum angle that the refrigerator door can open.

[0762] Compared with the structure of the hinge assembly currently on the market (compared with the solutions in the series of applications represented by CN115682517A), the refrigerator having the hinge assembly with the trajectory characteristics of some embodiments of the present disclosure has a reversing angle G' that is an acute angle or a right angle (CN115682517A is an obtuse angle), so that during the entire opening process of the door body 30 (the maximum opening angle is an obtuse angle), relative to the cabinet 10, the door body 30 has an instantaneous translational displacement of inward and forward translational movement while simply rotating, so that the moving door body 30 maintains an inward and forward translational movement while rotating relative to its previous state. During the above opening process of the door body 30, the door body 30 moves inward, on the one hand, compensating for the outward displacement of the first side edge W caused by the simple rotation of the door body 30, so as to limit the distance that the first side edge W exceeds the reference plane M0, and effectively avoid interference between the door body 30 and the storage cabinet 100 when it is opened. On the other hand, the distance between the door 30 and the storage cabinet 100 is increased, thereby reducing the limit imposed by the storage cabinet 100 on the maximum opening angle of the door 30 placed within the storage cabinet 100. Furthermore, the door 30 simultaneously moves forward, further reducing the limit imposed by the storage cabinet 100 on the maximum opening angle of the door 30 placed within the storage cabinet 100. In addition to simply rotating the door 30 to open, the door 30 also undergoes an inward and forward translational motion. These inward and forward translational movements work together to reduce the limit imposed by the storage cabinet 100 on the maximum opening angle of the door 30 placed within the storage cabinet 100. In addition, the door body 30 has the above-mentioned inward and forward translation tendency throughout the entire opening process, which allows the door body 30 to move out of the space defined by the storage cabinet 100 as much as possible, so that the maximum opening angle of the door body 30 placed in the storage cabinet 100 can reach an obtuse angle (settable, 115° and above or 120° and above), thereby achieving the purpose of placing the refrigerator in the storage cabinet 100 and being able to open it completely, making it convenient for users to take and put items.

[0763] It should be noted that the above description mainly uses some angles in the range of 0 to 90 degrees, 90 degrees, 90 degrees to G max =Some angles within the range of G8 are used as representatives to illustrate the overall movement trend of the door body 30, but they can represent the movement trend within the corresponding range, and can illustrate that the hinge assembly with the above trajectory characteristics disclosed in the present invention can enable the door body 30 to have an inward and forward translation movement trend throughout the entire rotation and opening process.

[0764] In summary, the hinge assembly with the trajectory characteristics in some embodiments of the present disclosure enables the door body 30 to move inward and forward while rotating during the opening process, and the trajectories (guide trajectory line S and guide trajectory line K) in some embodiments of the present disclosure are smooth and have no sharp points, effectively ensuring the smoothness and stability of the opening of the door body 30.

[0765] Combined with the above description of the process of opening the door body 30, next, the door body 30 is in the previous state (such as ) rotates around the midpoint of the axis line segment PQ relative to the door body 30 to the adjacent subsequent state (angle ) is in the position of the door body 30 in the present disclosure in the aforementioned adjacent state , so as to illustrate that under the setting of the hinge assembly with the trajectory feature of the present disclosure, the door body 30 has a tendency to move in translation relative to its previous state while rotating during the opening process.

[0766] As shown in Figures 33 to 39, assuming that the door body 30 rotates around the axis center point I of the previous state to the position of the adjacent subsequent state (the door body 30 is represented by a dotted line), during this movement, the rotation center of the door body 30 is fixed relative to the door body 30, and the rotation center of the door body 30 is the position of the axis center point I of the previous state on the door body 30. Then, under this movement trend, when the door body 30 opens to the adjacent subsequent state, the first side edge W is located at W' relative to the box body 10. The second side edge N is located at N' relative to the box body 10. The side sealing edge F is located at F' relative to the box body 10.

[0767] As shown in Figure 35, the position of the door body 30 indicated by the dotted line is the position reached when the door body 30 is simply rotated by the first angle G1 around the midpoint I (I0) of the axial line segment PQ of the door body 30 when the door body 30 is closed. The position of the door body 30 indicated by the solid line is the position reached when the door body 30 is rotated and opened to the first angle G1 under the restriction of the hinge assembly of the present disclosure. In Figure 36, the position of the door body 30 indicated by the dotted line is the position reached when the door body 30 is rotated and opened to the first angle G1 under the restriction of the hinge assembly of the present disclosure, and then simply rotated to the second angle G2 with the axial center point I of the door body 30 at the first angle G1 (the axial center point I (I1) of the previous state) as the center. The position of the door body 30 indicated by the solid line is the position reached when the door body 30 is rotated and opened to the second angle G2 under the restriction of the hinge assembly of the present disclosure. Similarly, Figures 35 to 42 are schematic diagrams comparing the positions of the two different opening methods described above at different opening angles. In summary, in FIG35 to FIG42, the position of the door body 30 indicated by the dotted line is the position where the door body 30 is rotated and opened to the i-th angle under the restriction of the hinge assembly of the present disclosure. Then, the door body 30 is at the i-th angle The relative axis center I of the door body 30 (the axis center I of the previous state (I i )) is the center of the simple rotation to the i+1th angle The position of the door body 30 indicated by the solid line is the position where the door body 30 is rotated and opened to the i+1th angle under the restriction of the hinge assembly of the present disclosure. The position reached when . Where i is any value from 0 to 7 and is an integer.

[0768] It should be noted that the comparison between the position of the door body 30 in the current state of the present disclosure and the position of the door body 30 when it is assumed to be simply rotated from the previous state of the present disclosure around the axis center point I to the position of the door body 30 when it is opened is representative and can represent the translation movement trend of the door body 30 relative to the previous state during the opening process of the door body 30 of the present disclosure. Set to 0°, G1, ... G7, the corresponding Set as G1, ... G8) for comparison and explanation to present the translation movement trend of the door body 30 when it rotates to open.

[0769] Comparing the arrangement disclosed herein (the door body 30 rotates around a point that is dynamically changing relative to the door body 30) with the arrangement in which the door body 30 simply rotates around the axis center point I in its previous state, it can be seen that:

[0770] The door 30 opens from the closed state to G max During the process, the first side edge position W is located on the side of W' close to the second body side wall and away from the access opening. The second side edge position N is located on the side of N' close to the second body side wall and away from the access opening. The side sealing edge position F is located on the side of F' close to the second body side wall and away from the access opening. That is, the door body 30 is opened from the closed state to G max During the opening and closing process, the door body 30 rotates open while tending to move inward and forward.

[0771] As shown in FIG43 , in the projection of the plane where the top wall of the box 10 is located, the door 30 is rotated open to the limit of the hinge assembly having the trajectory characteristics of the present application. When the axis center point I is located relative to the door body 30, it is recorded as the instantaneous axis center point I i , with the instantaneous axis center I i is the center of the circle, line segment I i W is the radius, I i W rotates along the opening direction of the door body 30 Then the position of point W' where the first side edge is located is obtained.

[0772] The door body 30 is Continue to open The rear opening angle is The first side edge moves to W. Comparing the positions of W' and W, it can be seen that the door body 30 is opened from the closed state to During the process, the position W of the first side edge is located at the side W' close to the side wall of the second body and away from the access opening. and All belong to 0°~G max Any of these values, and

[0773] Among them, the opening angle Open angle That is, the door body 30 is Continue to open to reach location, Infinitely approaching 0.

[0774] The above position comparison method is also applicable to the second side edge, side sealing edge and other points on the door body 30. And by comparison, it can be obtained that the door body 30 is opened from the closed state to the G max During the opening and closing process, the door body 30 rotates open while tending to move inward and forward.

[0775] It should be noted that the above can be used as a method to determine the translational movement trend of the door body 30 when it rotates to open, so as to explore the translational movement process of the door body 30 during the opening process. Any value between 0° and 10° can be used for comparison to intuitively display the translation trend. The smaller it is, the more accurate the translation trend between the two adjacent states is. Infinitely approaching 0.

[0776] In some embodiments of the present disclosure, the commutation angle G' is greater than 45° and less than or equal to 90°.

[0777] As a configurable manner, the commutation angle G' is any value between 75° and 80°.

[0778] As a configurable manner, the commutation angle G' is any value between 80° and 85°.

[0779] The arrangement of the hinge assembly with the above trajectory characteristics enables the door body 30 to move in the second direction during the process of opening from the closed state to 90 degrees. The transition from the first quadrant of the displacement coordinate system AOB to its third quadrant further increases the speed at which the door body 30 moves inward from the reversing angle G' to 90°, and can accelerate the inward movement distance of the door body 30 faster and more, thereby increasing the distance between the door front wall 31 and the inner wall of the storage cabinet 100 when the door body 30 is opened to 90°, and reducing the restriction of the storage cabinet 100 on the extreme angle of the door body 30 continuing to open from 90°.

[0780] In addition, with the arrangement of the hinge assembly having the above trajectory characteristics, the door body 30 is displaced in the second direction during the process of opening from the closed state to the reversing angle G'. Located in the first quadrant of the displacement coordinate system AOB, the first direction displacement Located in the second quadrant of the displacement coordinate system AOB, it effectively ensures the positive displacement of the door body 30 along the B axis when it is opened, so that the door body 30 can move forward quickly when it is opened, effectively reducing the amount of squeezing on the door seal 5.

[0781] In the above, during the opening process of the door body 30, the distance between the axis center point I and the door front wall 31 is the largest when the door body 30 is opened to the reversing angle G'. The above description is based on the example of the reversing angle G' being less than 90 degrees, that is, the reversing angle G' being an acute angle.

[0782] In some embodiments of the present disclosure, the reversing angle G'=G7=90°. That is, when the door body 30 is opened to 90°, the distance between the axis center point I and the door front wall 31 reaches a maximum value. In other words, the axis center point I moves to the reversing midpoint I'.

[0783] In the setting feature of the reversing angle G'=G7=90°, during the process of the door body 30 opening from the closed state to 90°, as shown in FIG31, the first direction displacement Pointing to the inner front side of the box 10 (inward and forward side), the second direction displacement Pointing to the outer front side of the box body 10 (outward and forward side), the specific process of the door body 30 moving is the same as the process of opening from the closed state to G' (G'<90°). That is, the first direction displacement The displacement on the A axis is The displacement on the B axis is Second direction displacement The displacement on the A axis is The displacement on the B axis is Among them, the trajectory feature settings of this disclosure are Then there is, That is, when the door body 30 is opened from the closed state to 90 degrees, in the displacement coordinate system AOB, the door body 30 has a first translation displacement and the second translation displacement That is, when the door body 30 is opened from the closed state to 90 degrees, the door body 30 rotates and opens relative to the box body 10 and has a movement tendency of moving inward and forward.

[0784] Under the setting characteristic of the reversing angle G'=G7=90°, the process of the door body 30 opening from 90° to G8 is the same as the corresponding stage mentioned above. The displacement on the A axis is The displacement on the B axis is Second direction displacement The displacement on the A axis is The displacement on the B axis is Among them, the trajectory feature settings of this disclosure are Then there is, That is, when the door 30 is opened from 90° to G8, in the displacement coordinate system AOB, the door 30 has a first translation displacement and the second translation displacement That is, when the door body 30 is opened from 90° to G8, the door body 30 rotates and opens relative to the box body 10 while having a movement tendency of moving inward and forward.

[0785] In summary, under the setting of the reversing angle G`=90°, compared with the setting of G`<90°, the door body 30 does not have the process of the door body 30 opening from G` to G7=90° (G`<G7=90°) (as shown in Figure 32).

[0786] In some embodiments of the present disclosure, G'=G6=G7=90°.

[0787] Based on the movement of the first shaft 41 relative to the guide portion 50 and the second shaft 42 relative to the guide portion 60 during the first, second, and third stages, during the opening process of the door body 30, the axis center point I moves relative to the door body 30 as the axis line segment PQ moves. The movement trajectory of the axis center point I relative to the door body 30 is recorded as the axis center point trajectory line. With respect to the door body 30, along the direction from the end of the door body 30 away from the door side wall 32 toward the door side wall 32, the distance between the axis center point I and the door front wall 31 first increases and then decreases. That is, the axis center point trajectory line extends from its end away from the door side wall 32 first in a direction away from the door front wall 31 and toward the door side wall 32, and then in a direction toward the door front wall 31 and the door side wall 32.

[0788] Among them, when the axis center point I moves to the reversing midpoint I', the distance between the axis center point trajectory and the door front wall 31 is the largest. At this time, the angle at which the door body 30 is opened is the reversing angle G'. That is, when the door body 30 is opened to the reversing angle G', the axis center point I moves to the reversing midpoint I' at the largest distance from the door front wall 31. As the door body 30 opens, the movement trend of the axis center point I changes at the reversing midpoint I' (from the direction close to the door side wall and away from the door front wall to the direction close to the door side wall and the door front wall), and the distance between the axis center point I and the door front wall 31 changes at the reversing midpoint I' (the distance between the axis center point I and the door front wall 31 changes from an increasing trend to a decreasing trend).

[0789] In some embodiments of the present disclosure, the commutation angle G' is a non-obtuse angle, that is, the commutation angle G' is an acute angle or a right angle.

[0790] When the commutation angle G' is set to an acute angle, the movement trend of the axis center point I is as follows:

[0791] When the door body 30 is opened from the closed state to the reversing angle G′, the center point I of the axis moves relative to the door body 30 toward the side wall 32 and away from the door front wall 31 to the reversing midpoint I′.

[0792] During the process of the door body 30 opening from the reversing angle G′ to the eighth angle G8, the center point I of the axis moves relative to the door body 30 from the reversing center point I′ to the side close to the door side wall 32 and the door front wall 31.

[0793] In some embodiments of the present disclosure, when the reversing angle G' is set to a right angle, the movement trend of the axis center point I is as follows:

[0794] During the process of the door body 30 opening from the closed state to 90 degrees, the center point I of the axis moves relative to the door body 30 toward the side wall 32 and away from the door front wall 31 to the reversing midpoint I'.

[0795] During the process of the door body 30 opening from 90° to the eighth angle G8, the center point I of the axis moves relative to the door body 30 from the reversing center point I′ to the side close to the door side wall 32 and the door front wall 31.

[0796] In some embodiments of the present disclosure, the door body 30 opens at an angle of When the first shaft 41 moves relative to the guide portion 50 toward the direction close to the side wall of the first body and the plane where the take-in / put-out opening is located.

[0797] In some embodiments of the present disclosure, the door body 30 opens at an angle of When the second shaft 42 moves relative to the guide portion 60 toward the direction close to the first body side wall and the plane where the take-in and put-out opening is located. Belongs to 0°~G max Any of these values.

[0798] That is, when the door 30 is opened from the closed state to the maximum angle G max During the rotational opening (eighth angle G8), the first shaft 41 and the second shaft 42 move synchronously relative to the guide portion 50 and 60 toward the first body sidewall and the access opening. This allows the door 30 to simultaneously move relative to the cabinet 10 toward the second body sidewall and away from the access opening during the rotational opening process, thereby reducing the maximum opening angle of the door 30 placed within the cabinet 100.

[0799] Correspondingly, the door body 30 opens at an angle of When the first central axis P moves relative to the guide portion 50 along the guide trajectory line S toward the direction close to the first body side wall and the plane where the take-in / put-out opening is located.

[0800] The door body 30 opens at an angle of When the second central axis Q moves relative to the guide portion 60 along the guide track line K toward the direction close to the first body side wall and the plane where the take-in and put-out opening is located. Belongs to 0°~G max Any of these values.

[0801] That is, when the door 30 is opened from the closed state to the maximum angle G max During the process of rotating and opening (the eighth angle G8), the first center axis P moves synchronously relative to the guide trajectory line S and the second center axis Q moves synchronously relative to the guide trajectory line K toward the first body side wall and the pick-up and release port, so that the door body 30 moves relative to the box body 10 toward the side close to the second body side wall and away from the pick-up and release port during the rotation and opening process, thereby reducing the restriction of the storage cabinet 100 on the maximum opening angle of the door body 30 placed in the storage cabinet 100.

[0802] In some embodiments of the present disclosure, the door body 30 opens at an angle of When the first central axis P is located at the instantaneous guide point of the guide trajectory line S The second central axis Q is located at the instantaneous guide point of the guide trajectory line K

[0803] Guidance trajectory S at instantaneous guidance point The tangent line at is recorded as the first instantaneous tangent line, which is determined by the instantaneous guide point The first body extends toward the side wall and the plane where the access opening is located.

[0804] Guidance trajectory K at the instantaneous guidance point The tangent at is recorded as the second instantaneous tangent, and the second instantaneous tangent is guided by the instantaneous point Extending in the direction close to the first body side wall and the plane where the access opening is located. Belongs to 0°~G max Any of these values.

[0805] The above arrangement enables the door body 30 to move relative to the box body 10 toward the second body side wall and away from the access opening during the rotational opening process, thereby reducing the limitation of the storage cabinet 100 on the maximum opening angle of the door body 30 placed in the storage cabinet 100.

[0806] In some embodiments of the present disclosure, the door body 30 opens at an angle of When the first central axis P is displaced relative to the guide trajectory line S, the instantaneous displacement is recorded as the first instantaneous displacement The instantaneous displacement of the second central axis Q relative to the guide trajectory line K is recorded as the second instantaneous displacement

[0921] As shown in FIG15 , the first reference plane M1 is a plane parallel to the reference plane M0 and perpendicular to the plane where the access opening is located. The first reference plane M1 is the plane where the inner wall of the storage cabinet 100 adjacent to the first body side wall is located. That is, the first reference plane M1 is parallel to the first body side wall and is at a distance α` from the first body side wall. The second reference plane M2 is the plane where the access opening of the storage chamber is located. The first reference plane M1 and the second reference plane M2 do not move during the opening of the door 30 relative to the cabinet 10 and are reference planes that remain stationary relative to the cabinet 10.

[0922] During the opening of the door 30, the first side edge W moves as the door 30 opens, and its motion trajectory is recorded as the first side edge trajectory. In the projection of the top wall of the box 10, during the opening of the door 30, the first side edge W first moves toward the first reference plane M1 and the second reference plane M2, and then moves away from the first reference plane M1 and toward the second reference plane M2.

[0923] In some embodiments of the present disclosure, when the door body 30 is opened to G2 , the first central axis P moves to the second guide point P2 of the guide trajectory line S.

[0924] At this time (when the door 30 is open to G2), the distance between the first side edge W and the reference plane M0 is at its maximum. This is to control the distance of the first side edge W approaching the first reference plane M1 to be less than the minimum distance between the refrigerator and the inner wall of the storage cabinet 100 when the door 30 is closed, thereby effectively preventing interference between the door 30 and the storage cabinet 100.

[0925] In some embodiments of the present disclosure, G2∈[16°, 25°]. That is, when the door body 30 is opened to a smaller angle, the first side edge W has moved to the position farthest from the first side wall during the entire opening process of the door body 30.

[0926] In some embodiments of the present disclosure, a linear first guide line and a curved second guide line are provided in conjunction with the guide trajectory line S. When the door 30 is opened, the distance between the first side edge W and the reference plane M0 is maximized when the first central axis P moves to the connection point between the first and second guide lines. Specifically, when the door 30 is opened, the distance between the first side edge W and the reference plane M0 is maximized when the first central axis P moves to the endpoint of the linear first guide line close to the door sidewall 32.

[0927] In some embodiments of the present disclosure, when the door body 30 is opened to G4, the first central axis P moves to the fourth guiding point P4 where the distance between the guiding trajectory line S and the door front wall 31 is the largest. At this point, the distance between the first side edge W and the reference plane M0 is the largest.

[0928] During the opening of the door 30, the second side edge N moves as the door 30 opens, and its motion trajectory is recorded as the second side edge trajectory. In the projection of the top wall of the box 10, during the opening of the door 30, the second side edge N first moves away from the first reference plane M1 and toward the second reference plane M2, and then moves away from the first reference plane M1 and the second reference plane M2.

[0929] In some embodiments of the present disclosure, when the door body 30 is opened to G2 , the first central axis P moves to the second guide point P2 of the guide trajectory line S.

[0930] At this time (when the door body 30 is opened to G2), the distance between the second side edge N and the second reference plane M2 is the smallest.

[0931] In some embodiments of the present disclosure, G2∈any value in the range [16°, 25°]. That is, when the door 30 is opened to a smaller angle, the second side edge N has moved to a position where its distance from the second reference plane M2 is minimum during the entire opening process of the door 30. This controls the distance of the second side edge toward the access opening to prevent interference between the second side edge N and the box body 10.

[0932] In some embodiments of the present disclosure, a straight first guide line and a curved second guide line are set in combination with the guide trajectory line S. When the door body 30 is opened, when the first center axis P moves to the connection point between the first guide line and the second guide line, the distance between the first side edge W and the reference plane M0 is the largest.

[0933] That is, when the door body 30 is opened, when the first central axis P moves to the end point of the linear first guide line close to the door side wall 32, the distance between the second side edge N and the plane where the access port is located (the second reference plane M2) is the smallest.

[0934] During the opening process of the door body 30 , the side sealing edge F moves as the door body 30 opens, and its movement trajectory is recorded as the side sealing edge trajectory line.

[0935] In the projection of the top wall of the box body 10, during the opening process of the door body 30, the side sealing edge F first moves in the direction away from the first reference plane M1 and close to the second reference plane M2, then moves in the direction away from the first reference plane M1 and the second reference plane M2, and then moves in the direction close to the first reference plane M1 and away from the second reference plane M2.

[0936] The above arrangement is in the final stage of the door body 30 opening, and the side sealing edge F moves outward, which can avoid the door body 30 blocking the access opening due to the side sealing edge F moving inward in the early stage of the door body 30 opening, thereby increasing the space utilization rate of the storage drawer to the horizontal size of the storage room.

[0937] In some embodiments of the present disclosure, when the door body 30 is opened to G1 , the distance between the side sealing edge F and the second reference plane M2 is the smallest.

[0938] In some embodiments of the present disclosure, G1∈[10°, 15°]. That is, when the door 30 is opened to a smaller angle, the side sealing edge F has moved to a position where its distance from the second reference plane M2 is minimum during the entire opening process of the door 30. This allows the door seal 5 to quickly move away from the box body 10, reducing the amount of pressure on the door seal 5 during the opening process of the door 30.

[0939] In some embodiments of the present disclosure, the door 30 is opened to G F When , the distance between the side sealing edge F and the side wall of the first body is the largest.

[0940] Open through door 30 to G F The plane parallel to the side sealing edge F of the first body is defined as the third reference plane M3. The third reference plane M3 does not move during the opening process of the door body 30 relative to the box body 10 and is a reference plane that remains stationary relative to the box body 10.

[0941] In some embodiments of the present disclosure, G F The angle is any value between 90° and 95°. The above limitation maximizes the distance between the side sealing edge F and the side wall of the first body when the door body 30 is opened to approximately 90°. This allows the side sealing edge F to move outward with a greater opening stroke in the later stages of the door body 30 opening, thereby further compensating for the inward movement of the side sealing edge F in the early stages of the door body 30 opening, thereby minimizing the obstruction of the access opening by the door body 30.

[0942] In some embodiments of the present disclosure, the door body 30 is opened from the closed state to the maximum angle G max During the process of (the eighth angle G8), the second side edge N is entirely located on the side of the third reference plane M3 close to the side wall of the first body.

[0943] In some embodiments of the present disclosure, when the door 30 is opened to the maximum angle G max During the process of (the eighth angle G8), the door sealing edge F is located between the second side edge N and the third reference plane M3 (including the third reference plane M3) to avoid the door body 30 opening at too large an angle and making the second side edge N the main factor affecting the lateral size of the obstructed access opening.

[0944] That is, during the opening process of the door body 30 , the second side edge N is always located outside the side sealing edge F.

[0945] That is, the door body 30 is made of G F To the maximum angle G max(Eighth angle G8) During the opening process, as the opening angle of the door body 30 increases, the obstruction of the door seal 5 on the access opening gradually decreases, and the obstruction of the door body 30 on the access opening gradually decreases, thereby increasing the lateral size of the drawer installed in the storage room, increasing the space utilization rate of the storage room, and making it convenient for users to take and place items stored on the door body shelf.

[0946] In some embodiments of the present disclosure, during the opening process of the door body 30 , the sum of the forces acting on the first shaft 41 and the second shaft 42 remains relatively constant.

[0947] In some embodiments of the present disclosure, the sum of the forces acting on the first shaft 41 and the second shaft 42 fluctuates within a range of [F to 3, F+3], where the unit is Newton.

[0948] In some embodiments of the present disclosure, during the closing process of the door body 30, when the door body 30 is closed to G1", the sum of the forces acting on the first shaft 41 and the second shaft 42 begins to increase as the door body 30 continues to close.

[0949] In some embodiments of the present disclosure, when the door 30 closes from G1 to G2, the sum of the forces acting on the first shaft 41 and the second shaft 42 increases to a maximum value during the entire process of opening or closing the door 30. When the door 30 continues to close from G2, the sum of the forces acting on the first shaft 41 and the second shaft 42 begins to decrease.

[0950] In some embodiments of the present disclosure, when the door body 30 is closed from G2`` to G3``, the sum of the forces acting on the first shaft 41 and the second shaft 42 is substantially equal to the sum of the forces acting when the door body 30 is closed to G1``.

[0951] In some embodiments of the present disclosure, the first hinge is provided with a first mating portion, and the second hinge is provided with a second mating portion configured to cooperate with the first mating portion to unlock or lock the door 30 and the box 10 .

[0952] When the door 30 is closed, the first mating portion contacts the second mating portion when the door 30 is closed to G1. When the door 30 is closed to G3, the first mating portion and the second mating portion are locked. As the door 30 closes from G1 to G3, the second mating portion first undergoes elastic deformation, converting it into elastic potential energy, which is then released to drive the door 30 to automatically close.

[0953] In some embodiments of the present disclosure, when the door body 30 is closed to G2″, the elastic deformation of the second matching portion is the largest.

[0954] In some embodiments of the present disclosure, the guide line S includes a first guide line. The first guide line is an arc.

[0955] In some embodiments of the present disclosure, a second guide line is connected to the first guide line at one end close to the door side wall 32. The second guide line is a curve.

[0956] Compared with the arrangement of the first guide line as a straight line and the arrangement of the first guide line as an arc, the arrangement of the first guide line as a straight line can move the first shaft 41 relative to the door body 30 toward the side closer to the door rear wall 33, thereby better exerting force on the first shaft 41 and reducing wear. In actual production and processing, compared with the processing of straight lines, it is difficult to control processing errors or have poor detectability for curved lines (including arcs), which can easily cause the door body 30 to open or close unsmoothly.

[0957] In some embodiments of the present disclosure, the guide line S includes a first guide line and a second guide line connected to an end of the first guide line close to the door side wall 32. The first guide line is an arc, and the second guide line is also an arc.

[0961] In some embodiments of the present disclosure, as shown in Figures 48 to 52, the guide trajectory line S includes a first guide line (P0P2), a second guide line (P2P2`) connected to one end of the first guide line near the door side wall 32, and a third guide line (P2`P8) connected to one end of the second guide line near the door side wall 32.

[0962] The first guide line is a straight line, the second guide line is an arc, and the third guide line is a straight line. The connection point between the first guide line and the second guide line is P2, and the connection point between the second guide line and the third guide line is P2'.

[0963] In some embodiments of the present disclosure, a first straight guide line extends from its end away from the door side wall 32 toward a direction close to the door side wall 32 and the door rear wall 33, a second arc-shaped guide line extends from the end of the first guide line close to the door side wall 32 first toward a direction close to the door side wall 32 and the door rear wall 33, and then extends toward a direction close to the door side wall 32 and the door front wall 31, and a third straight guide line extends toward a direction close to the door side wall 32 and the door front wall 31.

[0964] In some embodiments of the present disclosure, the first guide line, the second guide line, and the third guide line are sequentially connected tangentially.
