[0014] A limit block is provided at the lower end of the door body, and the limit block is located at the front end of the lower mounting block. When the door body rotates to the maximum position allowed, the limit block abuts against the side surface of the hinge plate, thereby stopping the door body from continuing to rotate;

[0015] When the door body is in a closed state, the first hinge axis is closer to the side wall and farther from the front wall than the second hinge axis;

[0016] A vertical distance L1 between the first hinge axis and the second hinge axis in the front-to-back direction satisfies 2.5 mm ≤ L1 ≤ 10 mm, and a vertical distance L2 between the first hinge axis and the second hinge axis in the left-to-right direction satisfies 7.5 mm ≤ L2 ≤ 30 mm;

Thus, a feature defined as "first", "second", "third", "fourth", and "fifth" may explicitly or implicitly include one or more of the features.

[0065] In the description of the present disclosure, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present disclosure can be understood according to specific circumstances.

[0066] Hereinafter, embodiments of the present application will be described in detail with reference to the accompanying drawings. In the accompanying drawings, a side of the refrigerator facing a user when in use is defined as a front side, and a side opposite thereto is defined as a rear side.

[0067] Figure 1 is a perspective view of a refrigerator according to some embodiments. Figure 1 The refrigerator 1 includes: a cabinet 10 having a storage chamber 20 , a door body 30 connected to the cabinet 10 to open and close the storage chamber 20 , and a cold air supply device that supplies cold air to the storage chamber 20 .

[0068] In some embodiments, the cool air supply device includes an evaporator, a compressor, a condenser, and an expansion device, and generates cool air by using latent heat of evaporation of a refrigerant.

[0069] In some embodiments, the cabinet 10 includes: an inner shell defining a storage chamber 20; an outer shell connected to the outside of the inner shell to form the appearance of the refrigerator 1; and an insulator provided between the inner shell and the outer shell to insulate the storage chamber 20.

[0070] In some embodiments, the cabinet 10 includes a horizontal partition plate that partitions the storage chamber 20 into an upper storage chamber 21 and a lower storage chamber 22, and a vertical partition plate that partitions the lower storage chamber 22 from one side to the other. The upper storage chamber 21 may be a refrigerator for storing food in a refrigerated mode by keeping the air at a temperature of about 0 to 5°C, and the lower storage chamber 22 may be a freezer for storing food in a frozen mode by keeping the air at a temperature of 0 to -30°C.

[0071] In some embodiments, the storage chamber 20 has an open front to allow food to be received and taken out, and the open front of the storage chamber 20 can be opened and closed by a rotatable door body 30 .

[0072] In some embodiments, the door body 30 is rotatably supported by a hinge located at an upper portion and a hinge located at a lower portion. For example, a hinge may be provided at an upper portion of the door body 30 to rotatably support the door body 30.

[0073] Figure 2 is a top view of a refrigerator according to some embodiments; Figure 3 yes Figure 2 A magnified image of area A; Figure 4 is an exploded view of the hinge at the upper right corner of a refrigerator according to some embodiments. Figures 2 to 4 The hinge includes a first hinge shaft 41, a second hinge shaft 42, a first track groove 50 and a second track groove 60; the first hinge shaft 41 is adapted to the first track groove 50, and the second hinge shaft 42 is adapted to the second track groove 60. During the process of the door body 30 rotating to open or close, the first hinge shaft 41 moves relatively in the first track groove 50, and the second hinge shaft 42 moves relatively in the second track groove 60.

[0074] The hinge at the upper end of the door body 30 includes a hinge plate 40 connected to the upper end of the box body 10, and a first hinge shaft 41 and a second hinge shaft 42 are connected to the hinge plate 40 to form a rotation axis. In some embodiments, the hinge plate 40, the first hinge shaft 41 and the second hinge shaft 42 are integrally formed; in other embodiments, the hinge plate 40, the first hinge shaft 41 and the second hinge shaft 42 are provided separately and assembled with each other.

[0075] Reference Figure 4 The hinge plate 40 includes: a connecting portion 401 having a substantially horizontal plate shape and connected to the box body 10; and an extending plate 402 extending forward from the connecting portion 401 and having a horizontal plate shape. The connecting portion 401 can be fastened to the box body 10 by fasteners such as screws, pins, and bolts.

[0076] In some embodiments, the first hinge shaft 41 and the second hinge shaft 42 are formed on the extension plate 402 and extend vertically downward.

[0077] Figure 5 is a bottom view of a hinge at a lower end of a door of a refrigerator according to some embodiments; Figure 6 is an exploded view of a hinge at the lower end of a door of a refrigerator according to some embodiments. Figure 5 , Figure 6 As shown, for the hinge at the lower end of the door body 30, the connecting portion 401 is connected to the front end surface of the box body 10. The first hinge shaft 41 and the second hinge shaft 42 extend upward on the hinge plate 40.

[0078] Corresponding to the position of the hinge plate 40 , the upper and lower ends of the door body 30 are both provided with a first track groove 50 and a second track groove 60 .

[0079] For the convenience of description, the side of the left and right sides of the door body 30 close to the hinge plate 40 is called the side wall 32. For example, when the hinge plate 40 is located on the right side of the box body 10, the right side of the door body 30 is the side wall 32; when the hinge plate 40 is located on the left side of the box body 10, the left side of the door body 30 is the side wall 32. The front wall 31 and the side wall 32 of the door body 30 meet to form a side edge 33.

[0080] Continue to refer to Figure 2 , the plane where the side of the box body 10 close to the hinge plate 40 is located is defined as the reference plane O, the side of the reference plane O close to the cabinet is the outer side, and the other side opposite to it is the inner side. When the refrigerator is placed in the cabinet 100 for use, in order to prevent factors such as uneven ground and deformation of the cabinet, the cabinet is usually set at a distance of α=5mm from the side of the refrigerator (reference plane O). In order to ensure that the door body 30 of the refrigerator opens normally, the side edge 33 of the door body 30 cannot exceed the side of the box body 10 (reference plane O) too much during the rotation process, otherwise, the side edge 33 collides with the cabinet 100 and cannot be opened normally.

[0081] Therefore, the door body 30 needs to be able to move inward during the rotation process so that the side edge 33 does not extend too far beyond the side of the box body 10. When the hinge plate 40 is arranged on the right side of the door body 30, the inner side is the left side, that is, the door body 30 can move to the left; when the hinge plate 40 is arranged on the left side of the door body 30, the inner side is the right side, that is, the door body 30 can move to the right.

[0082] Since the first track groove 50 and the first hinge shaft 41, and the second track groove 60 and the second hinge shaft 42 are in a relative motion relationship, if the door body 30 is opened, the first track groove 50 and the second track groove 60 are used as stationary reference objects, which is equivalent to the first hinge shaft 41 moving in the first track groove 50 and the second hinge shaft 42 moving in the second track groove 60. For the convenience of description, the present disclosure adopts the first track groove 50 and the second track groove 60 as reference objects, and introduces the way in which the first hinge shaft 41 and the second hinge shaft 42 move relative to the reference objects:

[0083] In some embodiments of the present application, when the door body 30 is rotated to open 90° from a closed state, the movement trajectory of the first hinge axis 41 relative to the first trajectory groove 50 generally extends in a direction close to the side wall 32 and the front wall 31, and the movement trajectory of the second hinge axis 42 relative to the second trajectory groove 60 generally extends in a direction away from the front wall 31 and close to the side wall 32, so that the door body 30 moves inward for a certain distance while rotating, thereby avoiding the problem that the side edge 33 of the door body 30 exceeds the reference plane O and interferes with the cabinet during the opening process, making it impossible to open normally.

[0084] Figure 7 FIG. 2 is a diagram showing the relative positions of the first hinge axis and the second hinge axis of the refrigerator according to some embodiments. Figure 7 When the door body 30 is in a closed state, the first hinge axis 41 is closer to the side wall 32 and farther from the front wall 31 than the second hinge axis 42. The vertical distance L1 between the first hinge axis 41 and the second hinge axis 42 in the front-to-back direction satisfies 2.5mm≤L1≤10mm, and the vertical distance L2 between the first hinge axis 41 and the second hinge axis 42 in the left-to-right direction satisfies 7.5mm≤L2≤30mm. For example, L1=5mm, L2=15mm are set, and the thickness of the door body 30 is between 44mm and 53mm, so that the corner of the door body 30 always exceeds the side of the box body 10 by a small distance during the opening process, specifically less than 3mm.

[0085] Figure 8 is a view of a refrigerator door in a closed state according to some embodiments. Fig. 9 for Figure 8 In some embodiments of the present disclosure, reference is made to Figure 8 and Fig. 9When the door body 30 is in a closed state, the first hinge axis 41 is located at the end of the first track groove 50, and the second hinge axis 42 is located at the end of the second track groove 60, thereby determining the starting ends of the first track groove 50 and the second track groove 60. The first track groove 50 generally extends from the starting end to the direction close to the side wall 32 and the front wall 31 to the other end, and the second track groove 60 generally extends from the starting end to the direction away from the front wall 31 and close to the side wall 32 to the other end. The first track groove 50 and the second track groove 60 extend in the direction close to the side wall 32 so that the door body 30 can move inward relative to the hinge plate 40.

[0086] In some embodiments, when the door body 30 is in a closed state, there is a certain gap between the second hinge shaft 42 and the lower end of the second track groove 60, so that when the door body 30 is dropped forcefully, the second hinge shaft 42 and the lower end of the second track groove 60 do not contact each other, thereby causing the door body 30 to bounce open.

[0087] The detailed process of rotating the door body 30 from the closed state to open is described below:

[0088] Phase 1

[0089] Fig.10 yes Figure 8 View at the center hinge, see Fig.10 The first trajectory groove 50 has a first positioning position 51 and a second positioning position 52, and the movement trajectory of the first hinge axis 41 from the first positioning position 51 to the second positioning position 52 in the first trajectory groove 50 is a first positioning trajectory line; correspondingly, the second trajectory groove 60 has a first guide position 61 and a second guide position 62, and the movement trajectory of the second hinge axis 42 from the first guide position 61 to the second guide position 62 in the second trajectory groove 60 is a first guide trajectory line.

[0090] Fig.11 FIG. 2 is a view of a refrigerator door in a first state according to some embodiments. Figure 8 , Fig.11 , when the door body 30 is Figure 8 Closed position shown, rotate open to Fig.11 In the first state shown, the first hinge axis 41 moves from the first positioning position 51 along the first positioning trajectory line to the second positioning position 52 relative to the first trajectory groove 50; at the same time, the second hinge axis 42 moves from the first guide position 61 along the first guide trajectory line to the second guide position 62 relative to the second trajectory groove 60.

[0091] Among them, the second positioning position 52 is farther away from the front wall 31 and closer to the side wall 32 than the first positioning position 51, and the first positioning trajectory line extends in the direction away from the front wall 31 and closer to the side wall 32. In this way, the first hinge axis 41 moves in the direction closer to the side wall 32 and away from the front wall 31, which is equivalent to the door body 30 with the first trajectory groove 50 moving a first distance away from the side wall 32 (inside) and a distance towards the front wall 31 (front side). The movement of the door body 30 inward can prevent the side edge 33 from exceeding the side of the box body 10 too much and touching the cabinet; because when the door body 30 is just opened, the right rear end of the door body 30 will rotate backward relative to the first hinge axis 41, as the door body 30 moves inward, the door seal 30a on the door body 30 will have contact and friction with the front side of the box body 10, and in the present application, the door body 30 is set to move forward, which can avoid friction between the door seal 30a and the front side of the box body 10 and improve the service life of the door seal 30a.

[0092] The second guide position 62 is farther from the front wall 31 and closer to the side wall 32 than the first guide position 61 , and the first guide track line extends in a direction away from the front wall 31 and closer to the side wall 32 .

[0093] In some embodiments, the first positioning trajectory is a first straight line 512, and the first guiding trajectory is a second straight line 612. However, in other embodiments, the first positioning trajectory and the first guiding trajectory may also be in the form of curves.

[0094] When the refrigerator door 30 is in the first state ( Fig.11 ), the opening angle of the door body 30 is about 5-10°, and the side edge 33 exceeds the side β of the box body 10 by about 2 mm.

[0095] In this stage, the angle between the first straight line 512 and the second straight line 612 is greater than 45°, which can prevent the door body 30 from shaking when the angle between the first straight line 512 and the second straight line 612 is small and close to parallel, thereby ensuring the stability of the door body 30 during rotation.

[0096] Phase II

[0097] Reference Fig.10 The first trajectory groove 50 also has a third positioning position 53, and the movement trajectory of the first hinge axis 41 from the second positioning position 52 to the third positioning position 53 in the first trajectory groove 50 is a second positioning trajectory line; correspondingly, the second trajectory groove 60 also has a third guide position 63, and the movement trajectory of the second hinge axis 42 from the second guide position 62 to the third guide position 63 in the second trajectory groove 60 is a second guide trajectory line.

[0098] Fig.13 FIG. 2 is a view showing a refrigerator door in a second state according to some embodiments. Fig.13 , when the door body 30 is Fig.11 The first state shown continues to open until Fig.13 In the second state shown, the second state is less than 90°, the first hinge axis 41 moves from the second positioning position 52 along the second positioning trajectory line to the third positioning position 53 relative to the first trajectory groove 50, and the second hinge axis 42 moves from the second guide position 62 along the second guide trajectory line to the third guide position 63 relative to the second trajectory groove 60.

[0099] The third positioning position 53 is closer to the front wall 31 and the side wall 32 than the second positioning position 52, and the second positioning trajectory extends from the second positioning position 52 to the third positioning position 53 in the direction close to the front wall 31 and the side wall 32, so that the door body 30 moves inward by a second distance.

[0100] The third guide position 63 is farther away from the front wall 31 and closer to the side wall 32 than the second guide position 62 , and the second guide track line extends in a direction away from the front wall 31 and closer to the side wall 32 .

[0101] In some embodiments, the second positioning trajectory is a first curve 523, and the second guiding trajectory is a second curve 623. However, in other embodiments, the second positioning trajectory and the second guiding trajectory may also be in the form of straight lines.

[0102] When the door body 30 is in a closed state, the center of curvature of the first curve 523 is located on a side of the first curve 523 close to the front wall; the center of curvature of the second curve 623 is located on a side of the second curve 623 close to the side edge.

[0103] The present invention divides the process of the door body 30 moving inward when opened into two different stages, namely, moving along a straight line to a first state and moving along a curve to a second state, which can avoid the problem of the door body 30 shaking when the trajectory is close to parallel when the door body rotates only along a straight line or only along a curve at a large angle.

[0104] In some embodiments, when the door body 30 is opened from the closed state to the second state, the side edge 33 of the door body 30 rotates outside the reference plane O and moves inward. In this process, the distance β of the side edge 33 beyond the reference plane O is always less than the distance α (5 mm) between the reference plane O and the cabinet, thereby ensuring that the side edge 33 does not touch the cabinet and interfere with it. At the same time, the side edge 33 of the door body 30 is outside the reference plane O, avoiding the problem of the user's feeling of frustration when opening the door when the door body 30 moves a large distance inward to the inside of the reference plane O.

[0105] In some embodiments, the distance from the second positioning position 52 to the third positioning position 53 is greater than the distance from the first positioning position 51 to the second positioning position 52, that is, the length of the first straight line 512 is smaller than the first curve 523, and the length of the second straight line 612 is smaller than the second curve 623. In this way, the first hinge axis 41 and the second hinge axis 42 only perform a linear movement of a small distance at the beginning, and then perform a curved movement at a larger angle. The curved movement can ensure the smoothness of the door body 30 during the movement process, and avoid the door body 30 moving inward when moving along a straight line, causing the user to feel a sense of error.

[0106] In some embodiments of the second stage, the first curve 523 and the second curve 623 each include at least two curve segments with decreasing curvatures.

[0107] In this way, the curvature of the curve becomes smaller, so that the distance that the door body 30 moves inward within a unit angle becomes smaller. That is to say, when the door body 30 moves inward when rotating to open the door, the inward movement slows down, ensuring the smoothness of the door body 30 during the movement process.

[0108] Reference Fig.12 , Fig.13 In some embodiments of curvature change, the first curve 523 includes a first curve segment 5231 and a third curve segment 5232 connected in sequence, and the second curve 623 includes a second curve segment 6231 and a fourth curve segment 6232 connected in sequence; the curvature of the third curve segment 5232 is smaller than that of the first curve segment 5231, and the curvature of the fourth curve segment 6232 is smaller than that of the second curve segment 6231.

[0109] When the first hinge axis 41 moves along the first curve segment 5231, the second hinge axis 42 moves along the second curve segment 6231. During this process, the door body 30 moves inward by a distance d1 when opening a unit angle. When the first hinge axis 41 continues to move along the third curve segment 5232, the second hinge axis 42 moves along the fourth curve segment 6232. During this process, the door body 30 moves inward by a distance d2 when opening a unit angle, d2<d1. As a specific example, d2 can be 1 / 2 of d1.

[0110] In other embodiments, the first curve 523 and the second curve 623 may also include three or more curve segments with decreasing curvatures.

[0111] In other embodiments of curvature change, the curvatures of the first curve 523 and the second curve 623 are gradually reduced, respectively. This can also ensure that the movement of the door body 30 slows down during the process of rotating the door to open inward, thereby ensuring the smoothness of the door body 30 during the movement process.

[0112] Phase 3

[0113] Fig.14 FIG. 2 is a view of a refrigerator door in a 90° open state according to some embodiments. Fig.14 , when the door body 30 is Fig.13 The second state shown continues to open until Fig.14 In the 90° state shown, the door body 30 only performs rotational movement, the position of the first hinge shaft 41 in the first track groove 50 remains unchanged, the door body 30 rotates with the first hinge shaft 41 as the center, and the second hinge shaft 42 moves along the third guide track line in the second track groove 60 to the fourth guide position 64. The third guide track line is an arc shape, and the fourth guide position 64 is farther away from the front wall 31 and closer to the side wall 32 than the third guide position 63.

[0114] In some embodiments, when the door body 30 is in a 90° open state, the front wall 31 or side edge 33 of the door body 30 has a vertical gap γ with the side surface (reference plane O) of the cabinet 10, that is, the front wall 31 of the door body 30 is located on the inner side of the reference plane O and the distance from the front wall 31 to the reference plane O is γ>0, so that the door body 30 can continue to open at a small angle without interfering with the cabinet. In the current example, when the refrigerator is set in the cabinet, the door body 30 can be opened>90°, about 105° to 110°.

[0115] In order to allow the refrigerator to be opened to a greater angle when not embedded in a cabinet, the first track groove 50 and the second track groove 60 are extended in this embodiment:

[0116] Stage 4

[0117] Reference Fig.10 The first trajectory groove 50 also has a first terminal position 54, and the movement trajectory of the first hinge axis 41 from the third positioning position 53 to the first terminal position 54 in the first trajectory groove 50 is a third positioning trajectory line; correspondingly, the second trajectory groove 60 also has a second terminal position 65, and the movement trajectory of the second hinge axis 42 from the fourth guide position 64 to the second terminal position 65 in the second trajectory groove 60 is a fourth guide trajectory line.

[0118] Fig.15 FIG. 2 is a view showing a refrigerator door in a maximum open state according to some embodiments. Fig.15 , when the door body 30 is Fig.14 When the 90° shown is continued to be opened, the first hinge axis 41 moves from the third positioning position 53 along the third positioning trajectory line relative to the first trajectory groove 50 to the first terminal position 54, and the second hinge axis 42 moves from the fourth guide position 64 along the fourth guide trajectory line relative to the second trajectory groove 60 to the second terminal position 65.

[0119] Among them, the first terminal position 54 is closer to the front wall 31 and the side wall 32 than the third positioning position 53, and the third positioning trajectory extends from the third positioning position 53 to the first terminal position 54 in the direction close to the front wall 31 and the side wall 32; the second terminal position 65 is closer to the front wall 31 and the side wall 32 than the fourth guide position 64, and the fourth guide trajectory extends from the fourth guide position 64 to the second terminal position 65 in the direction close to the front wall 31 and the side wall 32.

[0120] In the above description, the extension direction of the track line is based on the moving direction of the first hinge axis 41 relative to the first track groove 50 or the moving direction of the second hinge axis 42 relative to the second track groove 60 during the opening of the door body 30.

[0121] In the current embodiment, the third positioning trajectory line is the fourth curve 534, and the fourth guiding trajectory line is the fifth curve 645. However, in other embodiments, the third positioning trajectory line and the fourth guiding trajectory line may also be in the form of straight lines.

[0122] If the motion trajectory at this stage is still the same as that in the previous stage: the door body 30 only makes rotational motion, then it is easy for the movement trends of the first hinge axis 41 and the second hinge axis 42 to be parallel and the door body 30 to shake within a longer rotation range. Therefore, at this stage, the side edges of the door body 30 are arranged to move forward and inward for a certain distance during rotation, so that there is an angle between the motion trajectory of the first hinge axis 41 and the motion trajectory of the second hinge axis 42 at any point.

[0123] Specifically, the tangent angle between the motion trajectory of the first hinge shaft 41 and the motion trajectory of the second hinge shaft 42 at any corresponding point is greater than 30°, thereby ensuring the stability of the movement of the door body 30 .

[0124] In some embodiments of the present application, since the first hinge shaft 41 mainly plays a positioning role and the second hinge shaft 42 mainly plays a guiding role, among the two hinge shafts, the first hinge shaft 41 is the main shaft and the second hinge shaft 42 is the auxiliary shaft, and the force is mainly concentrated on the main shaft. Therefore, the length of the first hinge shaft 41 is set to be greater than the second hinge shaft 42, and accordingly, the first track groove 50 is deeper than the second track groove 60. This can avoid the waste of material costs caused by the second hinge shaft 42 being too long, and at the same time avoid the problem of the track groove and the hinge shaft being easily separated when the first hinge shaft 41 is shorter when the door body is tilted, thereby saving material costs on the basis of ensuring structural reliability.

[0125] In addition, since the force is concentrated on the first hinge shaft 41, the first hinge shaft 41 can be set to have a larger diameter than the second hinge shaft 42. In this way, the first hinge shaft 41 is thicker and can bear the force better, and has sufficient strength to withstand the force when the door body is tilted. At the same time, since the second track groove 60 is longer and occupies more space in the thickness direction of the door body, the second hinge shaft 42 is set to be thinner, and the second track groove 60 can be narrower accordingly, so that the door body can be designed to be thinner, and the thickness of the refrigerator as a whole can be smaller, which has the advantage of small size.

[0126] Fig.16 is a view of a hinge axis of a refrigerator according to some embodiments. Fig.16 The first hinge shaft 41 and the second hinge shaft 42 are provided with a sleeve 90, and the sleeve 90 can rotate relative to the shaft. During the movement of the double-axis hinge, the sleeve 90 rotates relative to the hinge shaft, and at the same time, the sleeve 90 slides with the track groove, which can reduce friction and increase service life. The sleeve 90 can be made of wear-resistant POM material, and the sleeve 90 can be connected to the hinge shaft through a bearing or connected to the hinge plate 40 through a bearing.

[0127] In other embodiments, a bushing made of POM material may also be provided on the inner wall of the track groove, and the hinge shaft moves in the bushing.

[0128] In some embodiments of the present application, reference Figures 17 to 20 The door body 30 includes a mounting block 70 , which is mounted on the door body 30 at a position opposite to the hinge plate 40 , and the first track groove 50 and the second track groove 60 are arranged on the mounting block 70 .

[0129] The mounting block 70 includes an upper mounting block 71 disposed at the upper end of the door body 30 , and a lower mounting block 72 disposed at the lower end of the door body 30 .

[0130] Specific reference Fig.17 , Fig.18 The upper mounting block 71 may include a plate body 711 and an extension portion 712 formed by extending downward from the lower surface of the plate body 711. The first track groove 50 and the second track groove 60 are recessed downward from the upper surface of the plate body 711 to the extension portion 712. The shape of the extension portion 712 corresponds to the track groove.

[0131] An upper receiving groove 34 is correspondingly provided at the upper end of the door body 30 , and the upper mounting block 71 is inserted into the upper receiving groove 34 , and then the plate body 711 is fastened to the door body 30 by screws or the like.

[0132] Specific reference Fig.19 , Fig. 20The lower mounting block 72 has the same structure as the plate body 711, the extension part 712, the track groove, etc. of the upper mounting block 71; the extension part 712 of the lower mounting block 72 is formed by extending upward from the upper surface of the plate body 711, and the first track groove 50 and the second track groove 60 are recessed upward from the lower surface of the plate body 711 to the extension part 712. At the same time, the lower end of the door body 30 is correspondingly provided with a lower receiving groove 36, and the lower mounting block 72 is inserted into the lower receiving groove 36, and then the plate body 711 is fastened to the door body 30 by screws or the like.

[0133] The upper mounting block 71 and the lower mounting block 72 may be made of POM material. POM has a strong friction resistance and can increase the service life of the hinge.

[0134] In some embodiments of the present application, Figure 6 The lower mounting block 72 may be provided with a locking hook structure, specifically, the lower mounting block 72 includes a locking hook 721 disposed on the inner side of the plate body 711. The locking hook 721 extends inward and is bent toward the rear side, the opening of the locking hook 721 faces the plate body 711, and the free end of the locking hook 721 is located at the rear side.

[0135] A stopper 403 extending outward is provided on the inner side of the hinge plate 40 located at the lower end of the door body 30. When the door body 30 is in a closed state, the lock hook 721 on the door body 30 hooks the stopper 403 on the hinge plate 40, thereby locking the door body 30 to prevent the door body 30 from being loosely closed and affecting the refrigeration and freezing effect of the refrigerator; when the door body 30 is opened, the lock hook 721 is deformed by the force and overcomes the obstruction of the stopper 403, thereby disengaging from the stopper 403.

[0136] The lock hook 721 may include a root connection portion 7211 and a hook portion 7212. The root connection portion 7211 is connected to the plate body 711, and the hook portion 7212 is connected to the root connection portion 7211 and bent backward. The screw is passed through the root connection portion 7211 and connected to the door body 30 to strengthen the connection strength between the root connection portion 7211 and the door body 30, so that when the lock hook 721 is separated from the stop portion 403, only the hook portion 7212 is deformed.

[0137] The free ends of the hook portion 7212 and the stop portion 403 are both in an arc shape, which is conducive to the hook portion 7212 hooking the stop portion 403 or detaching from the stop portion 403 along the arc.

[0138] In some embodiments, the door body 30 may be provided with a first protrusion 37 and a second protrusion 38. When the door body 30 is in a closed state, the first protrusion 37 and the second protrusion 38 are roughly arranged in a front-to-back relationship, and a gap groove 39 is formed between the first protrusion 37 and the second protrusion 38. A portion 7211a of the root connection 7211 is inserted into the gap groove 39. In this way, the root connection 7211 can be prevented from being deformed in the front-to-back direction by limiting the first protrusion 37 and the second protrusion 38.

[0139] It should be noted that the lock hook 721 can also be arranged on the upper mounting block 71 , and the stopper 403 is correspondingly arranged on the hinge plate 40 located at the upper end of the door body 30 .

[0140] In some embodiments of the present application, a limiting structure is provided between the door body 30 and the hinge plate 40 for limiting the door body 30 from opening to a maximum angle, so as to avoid damage to the mounting block 70 when the door is opened to a certain angle with great force.

[0141] Specifically, refer to Fig.19 , Fig.21 A limit block 80 is provided at the lower end of the door body 30, and the limit block 80 is located at the front end of the lower mounting block 72. When the door body 30 rotates to the maximum allowable position, the limit block 80 abuts against the side surface 404 of the hinge plate 40, thereby stopping the door body 30 from continuing to rotate.

[0142] The limiting block 80 may be a sheet metal component, including an embedding portion 81 , a limiting portion 82 and a reinforcing portion 83 .

[0143] The embedded portion 81 is plate-shaped and installed in the lower receiving groove 36 of the door body 30 . The plate body 711 of the lower mounting block 72 clamps the embedded portion 81 on the door body 30 from the lower end, thereby fixing the limiting block 80 on the door body 30 .

[0144] The reinforcing portion 83 and the embedding portion 81 form a vertical angle, that is, in the assembled state, the embedding portion 81 is in a horizontal state, and the reinforcing portion 83 is in a vertical state; the reinforcing portion 83 is formed by bending the front end of the embedding portion 81 downward.

[0145] The limiting portion 82 is block-shaped and is formed by the lower end portion of the reinforcing portion 83 continuing to extend downward. The limiting portion 82 extends vertically out of the lower surface of the door body 30, so that when the door body 30 drives the limiting block 80 to rotate to the maximum angle, the limiting portion 82 will be blocked by the side 404 of the hinge plate 40, thereby forcing the door body 30 to stop opening.

[0146] The limit block 80 is clamped on the door body 30 through the lower mounting block 72, and the connection structure between the limit block 80 and the door body 30 is omitted, which simplifies the product structure and has the advantage of simple structure.

[0147] It should be noted that the limit block 80 may also be arranged at the upper end of the door body 30, which will not be described in detail here.

[0148] If the distance between the first hinge axis 41 and the second hinge axis 42 is relatively far, when the door body 30 is tilted or the two axes are not parallel, the hinge movement is greatly affected, and even the normal rotation of the hinge is affected. Therefore, in some embodiments of the present application, reference is made to Fig.18The thickness of the plate 711 of the mounting block 70 is denoted as L1, and the minimum wall thickness between the first track groove 50 and the second track groove 60 is denoted as L2, then L2=(0.5~1)L1. This arrangement can make the distance between the first hinge axis 41 and the second hinge axis 42 closer, and the hinge movement is less affected when the door body is slightly tilted or the two axes are not parallel, and at the same time will not affect the strength of the mounting block 70.

[0149] In the above embodiment, the first track groove 50 and the second track groove 60 are arranged on the mounting block 70, and then the mounting block 70 is mounted on the door body 30. However, in other embodiments, the first track groove 50 and the second track groove 60 can also be directly arranged on the door body 30.

[0150] Reference Fig. 22 , Fig.23 As shown, the position on the door body 30 corresponding to the upper hinge plate 40 is recessed downward to form a first track groove 50 and a second track groove 60 ; the position on the door body 30 corresponding to the lower hinge plate 40 is recessed upward to form a first track groove 50 and a second track groove 60 .

[0151] Specifically, the door body 30 includes a door shell 301 and a protrusion 302 vertically extending from the door shell 301 to the inside thereof. The first track groove 50 and the second track groove 60 are formed by the outer end surface of the door shell 301 being recessed inwardly onto the protrusion 302.

[0152] The protrusion 302 can be integrally formed with the door shell 301. The protrusion 302 includes a first protrusion 303 and a second protrusion 304. The shape of the first protrusion 303 corresponds to the first track groove 50, and the shape of the second protrusion 304 corresponds to the second track groove 60.

[0153] The thickness of the door shell 301 is denoted as H1, and the minimum wall thickness between the first track groove 50 and the second track groove 60 is denoted as H2, then H2=(0.5~1)H1. This arrangement can make the distance between the first hinge axis 41 and the second hinge axis 42 closer, and the hinge movement is less affected when the door body is slightly tilted or the two axes are not parallel, and at the same time will not affect the strength of the mounting block 70.

[0154] In the above embodiment, the first hinge axis 41 and the second hinge axis 42 are arranged on the hinge plate 40, and the first track groove 50 and the second track groove 60 correspond to the door body 30; in other embodiments, the first hinge axis 41 and the second hinge axis 42 can be arranged on the door body 30, and the first track groove 50 and the second track groove 60 are arranged on the hinge plate 40; or, in another embodiment, the first hinge axis 41 and the second track groove 60 are arranged on the hinge plate 40, and the second hinge axis 42 and the first track groove 50 are arranged on the door body 30; or the first hinge axis 41 and the second track groove 60 are arranged on the door body 30, and the second hinge axis 42 and the first track groove 50 are arranged on the hinge plate 40.

[0155] According to the present application, by setting the door body 30 to move inwardly a first distance and forwardly a certain distance when initially opened, moving inwardly a first distance can ensure that the door body 30 will not interfere with the cabinet, and moving forwardly a certain distance can avoid the problem of wear caused by friction between the door seal 30a and the front side of the box body 10.

[0156] According to the present application, the process of the door body 30 rotating to open and moving inward is divided into two stages, that is, the movement trajectory of the first hinge axis 41 and the second hinge axis 42 is a straight line when opening from a closed state to a first state, and the movement trajectory of the first hinge axis 41 and the second hinge axis 42 is a curve when continuing to open from the first state to the second state. From the first state along a straight line to the second state along a curve, the problem of the door body 30 shaking due to the trajectory being close to parallel when the door body rotates only along a straight line or only along a curve at a large angle can be avoided; and the first hinge axis 41 and the second hinge axis 42 only perform a straight line movement of a small distance at the beginning, and perform a curved movement at a larger angle subsequently. The curved movement can ensure the smoothness of the door body 30 in the movement process, and avoid the door body 30 moving stiffly inward when moving along a straight line, causing the user to feel a sense of error.

[0157] According to the present application, when the door body 30 opens from the first state to the second state, the curved trajectory of the movement of the first hinge axis 41 and the second hinge axis 42 includes at least two curved segments with decreasing curvature, so that the distance the door body 30 moves inward within a unit angle becomes smaller, and the movement of the door body 30 slows down during the process of rotating the door to open the door and moving inward, thereby ensuring the smoothness of the door body 30 during the movement process.

[0158] According to the present application, when the door body 30 continues to open from 90°, the movement trajectory of the first hinge axis 41 is the fourth curve 534, and the movement trajectory of the second hinge axis 42 is the fifth curve 645, so that the movement trajectory of the first hinge axis 41 and the movement trajectory of the second hinge axis 42 have an angle at any point, thereby avoiding the problem of the door body 30 shaking easily when rotating within a larger angle range, thereby ensuring the smooth movement of the door body 30.

[0159] According to the present application, during the entire process of opening the door body 30, the first hinge shaft moves from one end of the first track groove to the other end, and the second hinge shaft moves from one end of the second track groove to the other end, and the movement process will not retract, thereby ensuring the smooth opening of the door body 30.

[0160] The above is only a specific embodiment of the present disclosure, but the protection scope of the present disclosure is not limited thereto. Any person skilled in the art who is familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present disclosure, which should be included in the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure should be based on the protection scope of the claims.
