Description

Technical Field

[0001] The present invention relates to the technical field of household appliances, and particularly to a refrigerator. Background Art

[0002] An embedded refrigerator generally embeds the whole refrigerator into a customized cabinet. For the fitting of the refrigerator into the external cabinet, the gap between the outer wall of the refrigerator and the inner wall of the cabinet is generally set very small. At this time, when the refrigerator door is opened, the vertical hinge side of the rotating door is very easy to hit the inner wall of the external cabinet. Limited by the space of the cabinet, in order to ensure that the door can be effectively opened, the corner of the door should not exceed the size of the box too much during the door opening process; and to ensure that the corner of the door does not exceed the size of the box too much during the door opening process, the door needs to move inward a certain distance when it is opened. At present, most embedded refrigerators control the displacement of the door along the width direction (inside and outside) of the box through the cooperation of shafts or grooves provided on the door or the box, so as to control the size of the corner of the door exceeding the box and achieve embedding.

[0003] In addition, when the refrigerator door is closed, the front wall of the door is flush with the plane where the cabinet opening is located to achieve a hidden installation. When the door is opened, the maximum opening angle of the door is limited by the cabinet. As the opening angle of the door increases, the front wall of the door approaches the end of the adjacent cabinet near its opening; when the front wall of the door contacts the end of the adjacent cabinet near its opening, limited by the cabinet, the door is opened to the limit position; the above leads to a limited maximum opening angle of the door of the refrigerator embedded in the cabinet. And controlling the displacement of the door along the width direction of the box to reduce the limitation of the space defined by the cabinet on the maximum opening angle of the door placed therein has limited effect. Summary of the Invention

[0004] The present application provides a refrigerator. The first shaft and the guiding part of the hinge assembly of the refrigerator are arranged on the box body, and the second shaft and the guiding part of the hinge assembly are arranged on the door body. The movement of the door body is guided by the different relative movement trends of the first shaft and the guiding part, and the second shaft and the guiding part at different stages, so as to increase the maximum opening angle of the refrigerator placed in the cabinet.

[0005] In a first aspect, a refrigerator is provided, including:

[0006] A box body, which defines a plurality of accommodating cavities with access openings; the box body has a first body side wall and a second body side wall arranged opposite to each other;

[0007] A door body, arranged on the box body to close or open the accommodating cavity; the door body has:

[0008] A front door wall, which is far from the door body when the door body is closed;

[0009] The door side wall is connected to the front wall of the door and is located on the side of the door body away from the second body side wall when the door is in the closed state;

[0010] A hinge assembly connects the door body to the box body so that the door body can be flipped relative to the box body; the hinge assembly includes:

[0011] A first hinge member is provided on the box body and is close to the first body side wall; the first hinge member includes:

[0012] A hinge plate is connected to the box body;

[0013] A first shaft and a guiding portion are provided on the hinge plate;

[0014] A second hinge member is provided on the door body; the second hinge member includes:

[0015] A second shaft is matched with the guiding portion;

[0016] A guiding portion is matched with the first shaft;

[0017] During the process of the door body being opened from G0 to G1, the second shaft moves to the side away from the first body side wall and the plane where the access opening is located, and the first shaft moves to the side close to the door side wall and away from the front wall of the door;

[0018] During the process of the door body being opened from G1 to G2, the second shaft moves to the side away from the first body side wall and close to the plane where the access opening is located, and the first shaft moves to the side close to the door side wall and away from the front wall of the door;

[0019] During the process of the door body being opened from G2 to G3, the second shaft moves to the side close to the first body side wall and away from the plane where the access opening is located, and the first shaft moves to the side close to the door side wall and away from the front wall of the door;

[0020] During the process of the door body being opened from G3 to G4, the second shaft moves to the side close to the first body side wall and the plane where the access opening is located, and the first shaft moves to the side close to the door side wall and away from the front wall of the door;

[0021] During the process of the door body being opened from G4 to G5, the second shaft moves to the side away from the first body side wall and the plane where the access opening is located, and the first shaft moves to the side close to the door side wall and the front wall of the door; where G0 < G1 < G2 < G3 < G4 < G5.

[0022] In the above technical solution, the movement directions of the first shaft relative to the guiding part and the second shaft relative to the guiding part are divided into five stages. Different relative movement trends in different stages guide the movement of the door body, so as to guide the door body to move in the width direction and the front-back direction of the cabinet, reduce the restriction of the cabinet on the door body, and increase the maximum opening angle that the door body can open in the cabinet.

[0023] In some embodiments, the first shaft is located on the side of the guiding part away from the side wall of the first body; the second shaft is located on the side of the guiding part close to the front wall of the door.

[0024] In the above technical solution, the relative positions of the first shaft and the guiding part and the relative positions of the second shaft and the guiding part are defined, making the structure of the hinge assembly more compact to ensure its strength.

[0025] In some embodiments, the movement trajectory of the central axis of the second shaft relative to the guiding part is denoted as the guiding trajectory line S. The guiding trajectory line S extends from the end away from the side wall of the first body first towards the side close to the side wall of the first body and away from the plane of the access opening, and then towards the side close to the side wall of the first body and the plane of the access opening.

[0026] In the above technical solution, the extension trend of the trajectory for guiding the movement of the central axis of the second shaft by the guiding part is defined. The extension trend of the guiding trajectory line is divided into two segments, and its trajectory extension trend is simple, improving the movement smoothness of the second shaft relative to the guiding part.

[0027] In some embodiments, the point with the maximum distance between the guiding trajectory line S and the plane of the access opening is denoted as the first guiding point P1;

[0028] During the opening process of the door body, when the opening angle of the door body is G1`, the distance between the central axis of the second shaft and the side wall of the first body is the smallest; the central axis of the second shaft is located at the first limit guiding point P1` of the guiding trajectory line S;

[0029] In the projection on the plane of the top wall of the cabinet, in the direction perpendicular to the plane of the access opening, the distance between the central axis of the first shaft and the first guiding point P1 is denoted as |QP1|1; the distance between the central axis of the first shaft and the first limit guiding point P1` is denoted as |QP1`|1;

[0030] Wherein, 0mm ≤ |QP1|1 ≤ 4mm, 0mm ≤ |QP1`|1 ≤ 2mm.

[0031] In the above technical solution, the limitation of 0 mm ≤ |QP1|1 ≤ 4 mm and 0 mm ≤ |QP1`|1 ≤ 2 mm jointly defines the extension trend of one section of the guiding trajectory line S, so that during the opening process of the door body, in the direction perpendicular to the plane where the picking and placing opening is located, the second axis is close to the first axis throughout the whole process, so as to effectively control the displacement of the door body relative to the box body in the direction perpendicular to the plane where the picking and placing opening is located, so as to control the movement amount of the door body relative to the box body in the width direction and the movement amount in the front-back direction, so that the total displacement in each stage can meet the requirements in each stage during the opening process of the door body, and at the same time reduce the restriction of the space defined by the cabinet 2 on the movement of the door body, so that the door body can be opened to a larger angle.

[0032] In some embodiments, the movement trajectory of the central axis of the first axis relative to the guiding portion is denoted as the guiding trajectory line F, and the guiding trajectory line F extends from the end far away from the door side wall to the side close to the door side wall and far away from the front door wall first, and then extends to the side close to the door side wall and the front door wall.

[0033] In the above technical solution, the extension trend of the trajectory of the guiding portion guiding the movement of the central axis of the first axis is defined. The extension trend of the guiding trajectory line is divided into two sections, and its trajectory extension trend is simple, which improves the movement smoothness of the first axis relative to the guiding portion.

[0034] In some embodiments, the point with the largest distance between the guiding trajectory line F and the front door wall is denoted as the third guiding point H;

[0035] In the plane projection parallel to the top wall of the box body, along the direction perpendicular to the door side wall, the distance between the central axis of the second axis and the third guiding point H is denoted as |PH|2; wherein, 0 mm ≤ |PH|2 ≤ 5 mm.

[0036] In the above technical solution, when 5 mm < |PH|2, |PH|2 is too large. In the direction perpendicular to the door side wall, the distance between the second axis and the third guiding point H with the largest distance from the front door wall on the guiding trajectory line is too large; during the movement of the door body relative to the box body, when the first central axis Q moves to the third guiding point H, the distance between the second central axis and the first central axis in the direction perpendicular to the door side wall is too large, and the inclination angle of the straight line where the first central axis and the second central axis are located relative to the plane where the picking and placing opening is located is too large. At this time, the stability of the door body relative to the box body during movement is poor.

[0037] In this application, the setting of 0 mm ≤ |PH|2 ≤ 5 mm makes the second axis close to the third guiding point H with the largest distance from the front door wall on the guiding trajectory line in the direction perpendicular to the door side wall; during the movement of the door body relative to the box body, when the first central axis Q moves to the third guiding point H, the second central axis is close to the first central axis in the direction perpendicular to the door side wall, effectively ensuring the stability of the door body relative to the box body during movement.

[0038] In some embodiments, the point on the guiding track line F that is farthest from the door sidewall and closest to the front wall of the door is denoted as the first guiding point K;

[0039] In the plane projection parallel to the top wall of the cabinet, along the direction perpendicular to the front wall of the door, the distance between the central axis of the second shaft and the first guiding point K is denoted as |PK|1; where 0 mm ≤ |PK|1 ≤ 3 mm.

[0040] In the above technical solution, when 3 mm < |PK|1, |PK|1 is too large. In the direction perpendicular to the front wall of the door, the distance between the second central axis P and the first guiding point K on the guiding track line that is farthest from the door sidewall is too large; during the movement of the door relative to the cabinet, when the first central axis Q reaches the first guiding point K, the distance between the second central axis and the first central axis in the direction perpendicular to the front wall of the door is too large, and the inclination angle of the straight line where the first central axis and the second central axis are located relative to the plane where the access opening is located is too large. At this time, the stability of the door relative to the cabinet during movement is poor.

[0041] In the present application, the setting of 0 mm ≤ |PK|1 ≤ 3 mm makes the second shaft close to the first guiding point K on the guiding track line that is farthest from the door sidewall in the direction perpendicular to the front wall of the door; during the movement of the door relative to the cabinet, when the door is closed and the first central axis Q reaches the first guiding point K, in the direction perpendicular to the door sidewall, the second central axis P is close to the first central axis, effectively ensuring the stability of the door relative to the cabinet during movement.

[0042] In some embodiments, when the opening angle of the door is G0, the front wall of the door is parallel to the plane of the access opening, or the door sidewall is perpendicular to the plane where the access opening is located.

[0043] In the above technical solution, the relative position of the door relative to the cabinet when the opening angle of the door is G0 is defined, making the relative position of the door and the cabinet more coordinated and aesthetically pleasing when the opening angle of the door is G0.

[0044] In a second aspect, a refrigerator is provided, including:

[0045] A cabinet that defines a plurality of accommodation cavities having access openings; the cabinet has a first body sidewall and a second body sidewall that are oppositely arranged;

[0046] A door disposed on the cabinet to close or open the accommodation cavity; the door has a door sidewall that is far from the second body sidewall when the door is closed;

[0047] A hinge assembly that connects the door to the cabinet to enable the door to flip relative to the cabinet; the hinge assembly includes:

[0048] A first hinge member, which is provided on the box body and close to the side wall of the first body; the first hinge member includes:

[0049] A hinge plate, which is connected to the box body;

[0050] A first shaft and a guiding portion, which are provided on the hinge plate;

[0051] A second hinge member, which is provided on the door body; the second hinge member includes:

[0052] A second shaft, which is matched with the guiding portion;

[0053] A guiding portion, which is matched with the first shaft; the guiding portion includes:

[0054] A first guiding end away from the side wall of the door and a second guiding end close to the side wall of the door;

[0055] During the process of the door body being opened from G0 to G5, the first guiding end gradually moves away from the first shaft, and the second guiding end gradually approaches the first shaft;

[0056] During the process of the door body being opened from G0 to G1, the second shaft moves to the side away from the plane of the side wall of the first body and the access opening; the first guiding end moves to the side away from the plane of the side wall of the first body and the access opening, and the second guiding end moves to the side away from the side wall of the first body and close to the plane of the access opening;

[0057] During the process of the door body being opened from G1 to G2, the second shaft moves to the side away from the side wall of the first body and close to the plane of the access opening; the first guiding end moves to the side close to the side wall of the first body and away from the plane of the access opening, and the second guiding end moves to the side away from the side wall of the first body and close to the plane of the access opening;

[0058] During the process of the door body being opened from G2 to G3, the second shaft moves to the side close to the side wall of the first body and away from the plane of the access opening; the first guiding end moves to the side close to the side wall of the first body and away from the plane of the access opening, and the second guiding end moves to the side away from the side wall of the first body and the plane of the access opening;

[0059] During the process of the door body being opened from G3 to G4, the second shaft moves to the side close to the side wall of the first body and the plane of the access opening; the first guiding end moves to the side close to the side wall of the first body and away from the plane of the access opening, and the second guiding end moves to the side away from the side wall of the first body and the plane of the access opening;

[0060] During the process of the door body being opened from G4 to G5, the second axis moves towards the side away from the plane of the first body side wall and the access opening; the first guiding end moves towards the side closer to the plane of the first body side wall and the access opening, and the second guiding end moves towards the side away from the plane of the first body side wall and the access opening; where G0 < G1 < G2 < G3 < G4 < G5.

[0061] In the above technical solution, the movement direction of the second axis relative to the guiding part, and the movement directions of the first guiding end and the second guiding end of the guiding part relative to the box body are divided into five stages. The different relative movement trends in different stages guide the movement of the door body, so as to guide the door body to move in the width direction and the front-back direction of the box body, so as to reduce the restriction of the cabinet on the door body and increase the maximum angle that the door body can be opened in the cabinet.

[0065] A hinge assembly that connects the door body to the box body so that the door body can be flipped relative to the box body; the hinge assembly includes:

[0066] A first hinge member arranged on the box body and close to the first body side wall; the first hinge member includes:

[0099] The terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features.

[0100] In the description of the present invention, it should be noted that unless otherwise clearly specified and limited, the terms "mounted", "connected", and "coupled" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0101] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.

[0102] An embodiment of the present application provides a refrigerator 100. Refer to Figures 1 - 20 , the refrigerator 100 includes a box body 1 having a receiving cavity, a door body 3 connected to the box body 1 to open and close the receiving cavity, and a refrigeration device for supplying cold air to the receiving cavity. The box body 1 includes an inner liner that defines the receiving cavity, an outer shell connected to the outside of the inner liner to form the appearance of the refrigerator 100, and a heat insulation layer disposed between the inner liner and the outer shell to insulate the receiving cavity.

[0103] Among them, refer to Figure 1 , the direction from the bottom wall to the top wall of the box body 1 is the height direction. The direction in which the intersection line of the top wall and the rear wall of the box body 1 extends is the width direction. The direction that is orthogonal to both the height direction and the width direction is the front-rear direction.

[0104] In some embodiments of the present application, the cabinet 1 defines a plurality of accommodation chambers. A pick-and-place opening for picking and placing items is formed at the front end of the accommodation chamber. Users can place food into the accommodation chamber or take food out of the accommodation chamber through the pick-and-place opening. A rotatable door body 3 is provided on the cabinet 1 to open or close the pick-and-place opening of the accommodation chamber. For example, the door body 3 is rotatably connected to the cabinet 1 through a hinge assembly located at the upper part and a hinge assembly located at the lower part. Among them, in the front-rear direction, relative to the wall surface (the rear wall of the cabinet 1) of the cabinet 1 opposite to the pick-and-place opening, the pick-and-place opening of the cabinet 1 is located on the front side.

[0105] In some embodiments of the present application, the plurality of accommodation chambers may include a refrigerating chamber and a freezing chamber to form accommodation chambers with different temperatures for storing different items.

[0106] In some embodiments of the present application, the cabinet 1 includes a first body side wall (i.e., one of the left side wall and the right side wall of the cabinet 1) and a second body side wall (i.e., the other of the left side wall and the right side wall of the cabinet 1) arranged opposite to each other along its width direction. The hinge assembly is provided on the cabinet 1 and close to the first body side wall to connect the door body 3 close to the first body side wall to the cabinet 1, so that the door body 3 can rotate relative to the cabinet 1 to open or close the pick-and-place opening.

[0107] The door body 3 has a front door wall 31 that is away from the cabinet 1 when the door body 3 is closed, a door rear wall 32 arranged opposite to the front door wall 31, and a door side wall 33 that is close to the first body side wall and connected to the front door wall 31. For example, when the hinge assembly is located on the right side of the cabinet 1, the right side wall of the door body 3 is the door side wall 33. When the hinge assembly is located on the left side of the cabinet 1, the left side wall of the door body 3 is the door side wall 33. It should be noted that the front door wall 31 is the most forward surface when the door body 3 is in the closed state. When the door body 3 includes a glass panel on its front side when it is in the closed state, the front door wall 31 is the most forward surface of the glass panel. And the door rear wall 32 is the surface closest to the rear side when the door body 3 is in the closed state. When the door body 3 is in the closed state, the distance between the front door wall 31 of the door body 3 and the plane where the pick-and-place opening is located is the largest, and the distance between the door rear wall 32 and the plane where the pick-and-place opening is located is the smallest.

[0108] In some embodiments of the present application, the door side wall 33 is connected to the front door wall 31 and close to the pivot axis of the door body 3. Among them, the pivot axis of the door body 3 is close to the first body side wall.

[0109] The front door wall 31 and the door side wall 33 of the door body 3 intersect to form a first side edge W, and the door side wall 33 and the door rear wall 32 intersect to form a second side edge N. When the door body 3 is closed, the first side edge W is located on the side away from the cabinet 1 of the second side edge N.

[0110] It should be noted that when both the front door wall 31 and the door side wall 33 are flat wall surfaces, the intersection line of the plane where the front door wall 31 is located and the plane where the door side wall 33 is located is the first side edge W. When the intersection of the front door wall 31 and the door side wall 33 is provided with a rounded transition, a curved surface extending along the height direction of the door body 3 (i.e., the height direction as shown in Figure 1 is formed. For the convenience of description, any straight line extending along the height direction of the door body 3 on this curved surface represents the first side edge W. Similarly, when the intersection of the rear door wall 32 and the door side wall 33 is provided with a rounded transition, the intersection line of the planes where the rear door wall 32 and the door side wall 33 are located can represent the second side edge N, or a straight line close to and parallel to this intersection line can be used to represent the second side edge N.

[0111] In some embodiments of the present application, a door seal is provided on the rear door wall 32 of the door body 3. Among them, when the door body 3 closes the access opening, the door seal surrounds the access opening to effectively seal the access opening. When the door body 3 is closed, the door seal fits against the front end surface of the box body 1 to effectively seal the connection between the door body 3 and the box body 1, thereby ensuring that the door body 3 seals the access opening and preventing cold air from leaking out.

[0112] In the present application, is used to represent the opening angle of the door body 3.

[0113] In some embodiments of the present application, the opening angle of the door body 3 The front door wall 31 is parallel to the plane where the access opening is located.

[0114] In some embodiments of the present application, the opening angle of the door body 3 The rear door wall 32 is perpendicular to the plane where the access opening is located.

[0115] In some embodiments of the present application, the opening angle of the door body 3 The door side wall 33 is parallel to the plane where the access opening is located.

[0116] In some embodiments of the present application, relative to the opening angle of the door body 3 When the door body 3 is opened relative to the box body 1 to open the access opening, the opening angle is a positive number.

[0117] When the door body 3 continues to move in the closing direction and further squeezes the door seal from then the opening angle of the door body 3 is a negative number.

[0118] In some embodiments of the present application, the opening angle of the door body 3 is recorded as the closed state.

[0119] In some embodiments of the present application, when the door body 3 is in the closed state, its opening angle That is, when the door body 3 is in the closed state, the deformation amount of the door seal squeezed by the door body 3 relative to Larger, the sealing effect between the door body 3 and the box body 1 is better. In some embodiments of the present application, when the door body 3 is in the closed state, its opening angle

[0120] In some embodiments of the present application, the hinge assembly includes a first hinge member and a second hinge member. The first hinge member is cooperated with the second hinge member and can rotate relative to each other, so that the door body 3 and the box body 1 can rotate relative to each other.

[0121] In some embodiments of the present application, the first hinge member is disposed on the box body 1 and close to one of the side walls of the body; in this embodiment, the case where the first hinge member is close to the first side wall is taken as an example for description. The second hinge member is disposed at the end of the door body 3 close to the first hinge member. The first hinge member is cooperated with the second hinge member to allow the box body 1 and the door body 3 to rotate relative to each other.

[0122] Refer to Figures 2 to 4 , the first hinge member includes a hinge plate 4. Specifically, the hinge plate 4 includes a connecting portion 41 connected to the box body 1 and an extending portion 42 extending forward from the connecting portion 41. The extending portion 42 can be set to be parallel to the top wall of the box body 1. The connecting portion 41 can be fastened to the top wall of the box body 1 by fasteners such as screws, pins and bolts. Specifically, for the hinge at the upper end of the door body 3, the connecting portion 41 is connected to the top wall of the box body 1. For the hinge at the lower end of the door body 3, the connecting portion 41 is connected to the front end face of the box body 1.

[0123] In some embodiments of the present application, the first hinge member includes a first shaft 5 and a guiding portion 7. Both the first shaft 5 and the guiding portion 7 are connected to the box body 1.

[0124] In some embodiments of the present application, both the first shaft 5 and the guiding portion 7 are disposed on the hinge plate 4. Among them, the first shaft 5 is located on the side of the guiding portion 7 away from the first side wall. The above settings enable the first shaft 5 and the guiding portion 7 to be arranged along the width direction of the box body 1, reducing the space occupied in the front-back direction of the box body 1 and making the structure of the first hinge member more compact.

[0125] The second hinge member includes: a second shaft 6 and a guiding portion 8. The second shaft 6 and the guiding portion 8 are located at the end of the door body 3 close to the first hinge member. Among them, the second shaft 6 is located on the side of the guiding portion 8 close to the front door wall 31.

[0126] Among them, the first shaft 5 is adapted to the guiding portion 8; the second shaft 6 is adapted to the guiding portion 7; during the process of the door body 3 rotating open or closed, the first shaft 5 moves relative to the guiding portion 8, and the second shaft 6 moves relative to the guiding portion 7, so that the door body 3 moves a certain distance at least along the width direction of the box body 1 while rotating open the access opening.

[0127] The central axis of the first shaft 5 is denoted as the first central axis Q. The central axis of the second shaft 6 is denoted as the second central axis P. When the door body 3 is opened, the locus line of the relative movement of the second central axis P with respect to the guiding portion 7 is denoted as the guiding locus line S.

[0128] In some embodiments of the present application, the guiding locus line S is a curve. The curve-shaped guiding locus line S protrudes towards the side away from the plane where the pick-and-place opening is located. That is, the guiding locus line S first extends from the end away from the first body side wall towards the side close to the first body side wall and away from the plane where the pick-and-place opening is located, and then extends towards the side close to the first body side wall and the plane where the pick-and-place opening is located. The above extension trend of the guiding locus line S is divided into two segments, and its locus extension trend is simple, which improves the movement smoothness of the second shaft relative to the guiding portion.

[0129] In some embodiments of the present application, the guiding locus line S is an arc, so that the movement of the second shaft 6 relative to the guiding portion 7 is smoother.

[0130] In some embodiments of the present application, the guiding portion 7 is arranged as a guiding groove. The guiding groove is a connected curved groove, and the curved groove protrudes towards the side away from the plane where the pick-and-place opening is located.

[0131] In some embodiments of the present application, the guiding groove is an arc groove.

[0132] In some embodiments of the present application, the guiding groove includes a guiding groove bottom, a circumferential guiding groove wall surrounding the guiding groove bottom, and a guiding groove opening defined by the circumferential guiding groove wall and oppositely arranged with respect to the guiding groove bottom. The second shaft 65 penetrates into the guiding groove through the guiding groove opening. The circumferential side wall of the second shaft 65 cooperates with the circumferential guiding groove wall of the guiding groove to guide the second shaft 65 when the second shaft 65 moves relative to the guiding groove. The above setting guides the second shaft 6 through its circumferential guiding groove wall, and its relative movement is more stable.

[0133] In some embodiments of the present application, the guiding groove includes a guiding groove opening arranged on the hinge plate 4. The second shaft 6 passes through the guiding groove opening, and the circumferential side wall of the second shaft 6 cooperates with the hinge plate 4 surrounding the guiding groove opening to guide the second shaft 6 when the second shaft 65 moves relative to the guiding groove. The above setting can achieve the purpose of guiding the second shaft 6 by the guiding groove, and is convenient for processing.

[0134] Refer to Figure 5 , in some embodiments of the present application, the center of the arc-shaped guiding locus line S is denoted as the guiding center O. The guiding center O is located on the side of the guiding locus line S close to the plane where the pick-and-place opening is located. Among them, the radius of the arc-shaped guiding locus line S is denoted as the guiding radius R.

[0135] In some embodiments of the present application, 8mm ≤ R ≤ 12mm.

[0136] When R < 8 mm, the guiding radius R is too small, and the curvature of the guiding track line S is too large, resulting in too rapid a change in the moving speed of the second shaft 6 relative to the guiding part 7.

[0137] When 12 mm < R, the guiding radius R is too large, and the curvature of the guiding track line S is too small, resulting in too small a change in the moving speed of the second shaft 6 relative to the guiding part 7, too long a length of the guiding track line, and the guiding part 7 occupying a large space of the hinge plate 4, leading to a reduction in the strength of the hinge plate 4 and also a reduction in the strength of the guiding part 7, reducing the service life of the hinge assembly.

[0138] When 8 mm ≤ R, it is possible to avoid too large a curvature of the guiding track line S resulting in too rapid a change in the moving speed of the second shaft 6 relative to the guiding part 7, so as to improve the stability of the movement of the door body 3 relative to the box body 1.

[0139] When R ≤ 12 mm, it is possible to avoid too small a moving speed of the second shaft 6 relative to the guiding part 7 due to too small a guiding track line S, so as to avoid too long a length of the guiding track line, reduce the space occupied by the guiding part 7 on the hinge plate 4, avoid a reduction in the strength of the hinge plate 4, and ensure the service life of the hinge assembly.

[0140] The setting of 8 mm ≤ R ≤ 12 mm above makes the movement of the second shaft 6 relative to the guiding part 7 more stable on the one hand, so as to improve the stability of the movement of the door body 3 relative to the box body 1. On the other hand, the area range occupied by the guiding part 7 on the hinge plate 4 is limited to ensure the strength of the hinge plate 4 and the guiding part 7, effectively ensuring the service life of the hinge assembly.

[0141] In the projection on the plane of the top wall of the box body 1, the guiding center O is located on the side of the first central axis Q close to the plane of the picking and placing opening and the first body side wall.

[0142] In some embodiments of the present application, the point with the maximum distance between the guiding track line S and the plane of the picking and placing opening is denoted as the first guiding point P1. The first central axis Q is located on the side of the first guiding point P1 close to the plane of the picking and placing opening and away from the first body side wall.

[0143] In some embodiments of the present application, during the opening process of the door body 3, when the opening angle of the door body 3, the distance between the second central axis P and the first body side wall is the smallest. At this time, the second central axis P is located at the first limit guiding point P1` of the guiding track line S.

[0144] When the opening angle of the door body 3, the distance between the second central axis P and the first body side wall is the largest. At this time, the second central axis P is located at the second limit guiding point P2` of the guiding track line S.

[0145] In some embodiments of the present application, in the projection on the plane of the top wall of the cabinet body 1, in the direction perpendicular to the plane where the access opening is located, the distance between the first central axis Q and the first guiding point P1 is denoted as |QP1|1; the distance between the first central axis Q and the first extreme guiding point P1` is denoted as |QP1`|1; the distance between the first central axis Q and the second extreme guiding point P2` is denoted as |QP2`|1.

[0146] In some embodiments of the present application, in the projection on the plane of the top wall of the cabinet body 1, the first guiding point P1, the first extreme guiding point P1`, and the second extreme guiding point P2` are all located on the side of the first central axis Q away from the plane where the access opening is located. That is, the trajectory segment of the guiding trajectory line S extending from the first extreme guiding point P1` through the first guiding point P1 to the second extreme guiding point P2` is located on the side of the first central axis Q away from the plane where the access opening is located.

[0147] In some embodiments of the present application, |QP1`|1 ≤ |QP1|1, |QP2`|1 ≤ |QP1|1. Among them, |QP1|1 = |QP1`|1 and |QP1|1 = |QP2`|1 do not hold simultaneously.

[0148] In some embodiments of the present application, 0mm ≤ |QP1|1 ≤ 4mm.

[0149] When 4mm < |QP1|1, when the second shaft 6 moves to the position where the distance between the guiding portion 7 and the plane where the access opening is located is the largest, the distance between the second shaft 6 and the first shaft 5 in the direction perpendicular to the plane where the access opening is located is too large, resulting in an excessive displacement of the door body 3 relative to the cabinet body 1 in the direction perpendicular to the plane where the access opening is located, and causing an imbalance between the movement amount of the door body 3 relative to the cabinet body 1 in the width direction and the movement amount in the front-back direction, and the limitation of the space defined by the cabinet 2 on the movement of the door body 3 cannot be effectively reduced.

[0150] In the present application, the setting of 0mm ≤ |QP1|1 ≤ 4mm enables the second shaft 6 to approach the first shaft 5 in the direction perpendicular to the plane where the access opening is located when the second shaft 6 moves to the position where the distance between the guiding portion 7 and the plane where the access opening is located is the largest, effectively controlling the displacement amount of the door body 3 relative to the cabinet body 1 in the direction perpendicular to the plane where the access opening is located, so as to control the movement amount of the door body 3 relative to the cabinet body 1 in the width direction and the movement amount in the front-back direction, reducing the limitation of the space defined by the cabinet 2 on the movement of the door body 3, and enabling the door body 3 to be opened to a larger angle.

[0151] In some embodiments of the present application, 0mm ≤ |QP1`|1 ≤ 2mm.

[0152] When 2 mm < |QP1`|1, when the second shaft 6 moves to the position where the distance between the guiding part 7 and the side wall of the first body is the smallest, the distance between the second shaft 6 and the first shaft 5 in the direction perpendicular to the plane where the pick-and-place opening is located is too large, resulting in an excessive displacement of the door body 3 relative to the cabinet body 1 in the direction perpendicular to the plane where the pick-and-place opening is located, resulting in an imbalance between the movement amount of the door body 3 relative to the cabinet body 1 in the width direction and the movement amount in the front-back direction, and the restriction of the space defined by the cabinet 2 on the movement of the door body 3 cannot be effectively reduced.

[0153] In this application, the setting of 0 mm ≤ |QP1`|1 ≤ 2 mm enables the second shaft 6 to approach the first shaft 5 in the direction perpendicular to the plane where the pick-and-place opening is located when the second shaft 6 moves to the position where the distance between the guiding part 7 and the side wall of the first body is the smallest, effectively controlling the displacement amount of the door body 3 relative to the cabinet body 1 in the direction perpendicular to the plane where the pick-and-place opening is located, so as to control the movement amount of the door body 3 relative to the cabinet body 1 in the width direction and the movement amount in the front-back direction, so as to reduce the restriction of the space defined by the cabinet 2 on the movement of the door body 3 and enable the door body 3 to be opened to a larger angle.

[0154] In some embodiments of this application, 0 mm ≤ |QP2`|1 ≤ 3 mm.

[0155] When 3 mm < |QP2`|1, when the second shaft 6 moves to the position where the distance between the guiding part 7 and the side wall of the first body is the largest, the distance between the second shaft 6 and the first shaft 5 in the direction perpendicular to the plane where the pick-and-place opening is located is too large, resulting in an excessive displacement of the door body 3 relative to the cabinet body 1 in the direction perpendicular to the plane where the pick-and-place opening is located, resulting in an imbalance between the movement amount of the door body 3 relative to the cabinet body 1 in the width direction and the movement amount in the front-back direction, and the restriction of the space defined by the cabinet 2 on the movement of the door body 3 cannot be effectively reduced.

[0156] In this application, the setting of 0 mm ≤ |QP2`|1 ≤ 3 mm enables the second shaft 6 to approach the first shaft 5 in the direction perpendicular to the plane where the pick-and-place opening is located when the second shaft 6 moves to the position where the distance between the guiding part 7 and the side wall of the first body is the largest, effectively controlling the displacement amount of the door body 3 relative to the cabinet body 1 in the direction perpendicular to the plane where the pick-and-place opening is located, so as to control the movement amount of the door body 3 relative to the cabinet body 1 in the width direction and the movement amount in the front-back direction, so as to reduce the restriction of the space defined by the cabinet 2 on the movement of the door body 3 and enable the door body 3 to be opened to a larger angle.

[0157] Above, the limitations of 0 mm ≤ |QP1|1 ≤ 4 mm, 0 mm ≤ |QP1`|1 ≤ 2 mm, and 0 mm ≤ |QP2`|1 ≤ 3 mm jointly define the overall trend of the guiding trajectory line S, such that during the opening process of the door body 3, in the direction perpendicular to the plane where the pick-and-place opening is located, the second shaft 6 approaches the first shaft 5 throughout the process, effectively controlling the displacement of the door body 3 relative to the cabinet body 1 in the direction perpendicular to the plane where the pick-and-place opening is located, controlling the movement amount of the door body 3 relative to the cabinet body 1 in the width direction and the movement amount in the front-rear direction, enabling the total displacement in each stage to meet the requirements of each stage during the opening process of the door body 3, and at the same time reducing the restriction of the space defined by the cabinet 2 on the movement of the door body 3, allowing the door body 3 to open to a larger angle.

[0158] In some embodiments of the present application, 20° ≤ ∠P1`OP2` ≤ 30°.

[0159] When ∠P1`OP2` < 20°, ∠P1`OP2` is too small, the length of the guiding trajectory line is too small, the length of the guiding portion 7 is too small, and the relative friction times when the second shaft 6 moves relative to the guiding portion 7 are many, increasing the wear of the second shaft 6 and the guiding portion 7 and reducing the service life of the hinge assembly.

[0160] When 30° < ∠P1`OP2`, ∠P1`OP2` is too large, the length of the guiding trajectory line is too large, the length of the guiding portion 7 is too large, the space occupied by the guiding portion 7 in the hinge plate 4 is large, resulting in a reduction in the strength of the hinge plate 4 and also a reduction in the strength of the guiding portion 7, reducing the service life of the hinge assembly.

[0161] When 20° ≤ ∠P1`OP2`, the length of the guiding trajectory line is limited within a reasonable range, the relative friction times when the second shaft 6 moves relative to the guiding portion 7 are limited, reducing the wear of the second shaft 6 and the guiding portion 7 and ensuring the service life of the hinge assembly.

[0162] When ∠P1`OP2` ≤ 30°, the length of the guiding trajectory line is limited within a reasonable range, reducing the space occupied by the guiding portion 7 in the hinge plate 4, avoiding a reduction in the strength of the hinge plate 4, and ensuring the service life of the hinge assembly.

[0163] When 20° ≤ ∠P1`OP2` ≤ 30° is set to limit the length of the guiding trajectory line (guiding portion 7). On the one hand, it reduces the relative friction times when the second shaft 6 moves relative to the guiding portion 7 to reduce the wear of the second shaft 6 and the guiding portion 7; on the other hand, it reduces the space occupied by the guiding portion 7 in the hinge plate 4, avoiding a reduction in the strength of the hinge plate 4 and ensuring the service life of the hinge assembly.

[0164] In some embodiments of the present application, 12° ≤ ∠P1`OP1 ≤ 20°.

[0165] The stroke of the second shaft 6 moving relative to the guiding part 7 between the first guiding point P1 and the first extreme guiding point P1' is denoted as the first stroke.

[0166] When ∠P1'OP1 < 12°, ∠P1'OP1 is too small, the first stroke of the second shaft 6 moving relative to the guiding part 7 between the first guiding point P1 and the first extreme guiding point P1' is too small, and the first stroke where the amount of movement of the door body 3 relative to the cabinet body 1 in the width direction and the amount of movement in the front-back direction are appropriate is too small, and the restriction of the space defined by the cabinet 2 on the movement of the door body 3 cannot be effectively reduced.

[0167] When 20° < ∠P1'OP1, ∠P1'OP1 is too large. During the process of the second shaft 6 moving relative to the guiding part 7 between the first guiding point P1 and the first extreme guiding point P1', there is a situation where the distance between the second shaft 6 and the first shaft 5 in the direction perpendicular to the plane where the access opening is located is too large, resulting in the displacement amount of at least one section of the door body 3 relative to the cabinet body 1 in the direction perpendicular to the plane where the access opening is located being too large during the movement process, resulting in the imbalance between the amount of movement of the door body 3 relative to the cabinet body 1 in the width direction and the amount of movement in the front-back direction, and the restriction of the space defined by the cabinet 2 on the movement of the door body 3 cannot be effectively reduced.

[0168] When 12° ≤ ∠P1'OP1, the first stroke of the second shaft 6 moving relative to the guiding part 7 between the first guiding point P1 and the first extreme guiding point P1' meets the movement requirements of the door body 3, and the first stroke where the amount of movement of the door body 3 relative to the cabinet body 1 in the width direction and the amount of movement in the front-back direction are appropriate meets the movement requirements of the door body 3, and the restriction of the space defined by the cabinet 2 on the movement of the door body 3 can be effectively reduced.

[0169] When ∠P1'OP1 ≤ 20°, during the process of the second shaft 6 moving relative to the guiding part 7 between the first guiding point P1 and the first extreme guiding point P1', in the direction perpendicular to the plane where the access opening is located, the second shaft 6 approaches the first shaft 5, effectively controlling the amount of movement of the door body 3 relative to the cabinet body 1 in the width direction and the amount of movement in the front-back direction, and the restriction of the space defined by the cabinet 2 on the movement of the door body 3 can be effectively reduced.

[0170] In the present application, the setting of 12° ≤ ∠P1'OP1 ≤ 20° enables the second shaft 6 to move. During the process of the guiding part 7 moving between the first guiding point P1 and the first extreme guiding point P1', in the direction perpendicular to the plane where the access opening is located, the amount of movement of the door body 3 relative to the cabinet body 1 in the width direction and the amount of movement in the front-back direction are appropriate, and the stroke is appropriately satisfied with the movement requirements of the door body 3, so as to more efficiently reduce the restriction of the space defined by the cabinet 2 on the movement of the door body 3.

[0171] In some embodiments of the present application, 7° ≤ ∠P2'OP1 ≤ 11°.

[0172] Among them, the stroke of the second shaft 6 moving relative to the guiding part 7 between the first guiding point P1 and the second extreme guiding point P2` is denoted as the second stroke.

[0173] When ∠P2`OP1 < 7°, ∠P2`OP1 is too small, the second stroke of the second shaft 6 moving relative to the guiding part 7 between the first guiding point P1 and the second extreme guiding point P2` is too small, and the second stroke where the amount of movement of the door body 3 relative to the cabinet body 1 in the width direction and the amount of movement in the front-rear direction are appropriate is too small, and the restriction of the space defined by the cabinet 2 on the movement of the door body 3 cannot be effectively reduced.

[0174] When 11° < ∠P2`OP1, ∠P2`OP1 is too large. During the process of the second shaft 6 moving relative to the guiding part 7 between the first guiding point P1 and the second extreme guiding point P2`, there is a situation where the distance between the second shaft 6 and the first shaft 5 in the direction perpendicular to the plane where the access opening is located is too large, resulting in the displacement amount of at least one section of the door body 3 relative to the cabinet body 1 in the direction perpendicular to the plane where the access opening is located being too large during the movement process, resulting in an imbalance between the amount of movement of the door body 3 relative to the cabinet body 1 in the width direction and the amount of movement in the front-rear direction, and the restriction of the space defined by the cabinet 2 on the movement of the door body 3 cannot be effectively reduced.

[0175] When 7° ≤ ∠P2`OP1, the second stroke of the second shaft 6 moving relative to the guiding part 7 between the first guiding point P1 and the second extreme guiding point P2` meets the movement requirements of the door body 3, and the second stroke where the amount of movement of the door body 3 relative to the cabinet body 1 in the width direction and the amount of movement in the front-rear direction are appropriate meets the movement requirements of the door body 3, and the restriction of the space defined by the cabinet 2 on the movement of the door body 3 can be effectively reduced.

[0176] When ∠P2`OP1 ≤ 11°, during the process of the second shaft 6 moving relative to the guiding part 7 between the first guiding point P1 and the second extreme guiding point P2`, in the direction perpendicular to the plane where the access opening is located, the second shaft 6 approaches the first shaft 5, effectively controlling the amount of movement of the door body 3 relative to the cabinet body 1 in the width direction and the amount of movement in the front-rear direction, and the restriction of the space defined by the cabinet 2 on the movement of the door body 3 can be effectively reduced.

[0177] In this application, the setting of 7° ≤ ∠P2`OP1 ≤ 11° enables the second shaft 6 to move to a position where during the movement of the guiding part 7 between the first guiding point P1 and the second extreme guiding point P2`, in the direction perpendicular to the plane where the access opening is located, the amount of movement of the door body 3 relative to the cabinet body 1 in the width direction and the amount of movement in the front-rear direction are appropriate, and the stroke is appropriate, so as to more efficiently reduce the restriction of the space defined by the cabinet 2 on the movement of the door body 3.

[0178] In some embodiments of this application, 1.6 ≤ ∠P1`OP1: ∠P2`OP1 ≤ 2.

[0179] When ∠P1`OP1:∠P2`OP1 < 1.6, ∠P1`OP1:∠P2`OP1 is too small, and the first stroke is too small. The movement amount of the door body 3 relative to the cabinet body 1 in the width direction and the movement amount in the front-rear direction are appropriately too small in the first stroke, and the restriction of the space defined by the cabinet 2 on the movement of the door body 3 cannot be effectively reduced. In addition, the ratio of the first stroke to the second stroke is too small, and the allocation of the first stroke and the second stroke of the door body 3 relative to the cabinet body 1 during movement is unbalanced, and the displacement amount requirements at each stage of opening the door body 3 cannot be met.

[0180] When 2 < ∠P1`OP1:∠P2`OP1, ∠P1`OP1:∠P2`OP1 is too large, and the first stroke is too large. There is a situation where the distance between the second shaft 6 and the first shaft 5 in the direction perpendicular to the plane where the access opening is located is too large, resulting in an excessive displacement amount of at least one section of the door body 3 relative to the cabinet body 1 in the direction perpendicular to the plane where the access opening is located, resulting in an imbalance between the movement amount of the door body 3 relative to the cabinet body 1 in the width direction and the movement amount in the front-rear direction, and the restriction of the space defined by the cabinet 2 on the movement of the door body 3 cannot be effectively reduced. In addition, the ratio of the first stroke to the second stroke is too large, and the allocation of the first stroke and the second stroke of the door body 3 relative to the cabinet body 1 during movement is unbalanced, and the displacement amount requirements at each stage of opening the door body 3 cannot be met.

[0181] When 1.6 ≤ ∠P1`OP1:∠P2`OP1, the first stroke meets the movement requirements of the door body 3. The movement amount of the door body 3 relative to the cabinet body 1 in the width direction and the movement amount in the front-rear direction are appropriately such that the first stroke meets the movement requirements of the door body 3, and the restriction of the space defined by the cabinet 2 on the movement of the door body 3 can be effectively reduced. In addition, the ratio of the first stroke to the second stroke is limited within a suitable range to control the relative amount of the first stroke and the second stroke of the door body 3 relative to the cabinet body 1 during movement, and the displacement amount requirements at each stage of opening the door body 3 can be met.

[0182] When ∠P1`OP1 ≤ 20°, during the movement of the first stroke, in the direction perpendicular to the plane where the access opening is located, the second shaft 6 approaches the first shaft 5, effectively controlling the movement amount of the door body 3 relative to the cabinet body 1 in the width direction and the movement amount in the front-rear direction, and the restriction of the space defined by the cabinet 2 on the movement of the door body 3 can be effectively reduced. In addition, the ratio of the first stroke to the second stroke is limited within a suitable range to control the relative amount of the first stroke and the second stroke of the door body 3 relative to the cabinet body 1 during movement, and the displacement amount requirements at each stage of opening the door body 3 can be met.

[0183] In this application, the setting of 1.6 ≤ ∠P1`OP1:∠P2`OP1 ≤ 2 enables, during the movement in the first stroke, that in the direction perpendicular to the plane where the access opening is located, the amount of movement of the door body 3 relative to the cabinet body 1 in the width direction and the amount of movement in the front-rear direction are appropriate, and the stroke is appropriately satisfied with the movement requirements of the door body 3, so as to more efficiently reduce the restriction of the space defined by the cabinet 2 on the movement of the door body 3. In addition, the ratio of the first stroke to the second stroke is limited within a suitable range to control the relative amount of the first stroke and the second stroke when the door body 3 moves relative to the cabinet body 1, and can meet the displacement amount requirements at each stage of the opening of the door body 3.

[0184] In the projection on the plane of the top wall of the cabinet body 1, in the direction perpendicular to the plane where the access opening is located, the distance between the first central axis Q and the guiding center O is denoted as |QO|1. 3 ≤ |QO|1:|QP1|1.

[0185] When |QO|1:|QP1|1 < 3, |QO|1:|QP1|1 is too small. When the second shaft 6 moves to the position where the distance between the guiding part 7 and the plane where the access opening is located is the largest, the distance between the second shaft 6 and the first shaft 5 in the direction perpendicular to the plane where the access opening is located is too large, resulting in an excessive displacement amount of the door body 3 relative to the cabinet body 1 in the direction perpendicular to the plane where the access opening is located, leading to an imbalance between the amount of movement of the door body 3 relative to the cabinet body 1 in the width direction and the amount of movement in the front-rear direction, and unable to effectively reduce the restriction of the space defined by the cabinet 2 on the movement of the door body 3.

[0186] In this application, the setting of 3 ≤ |QO|1:|QP1|1 enables that when the second shaft 6 moves to the position where the distance between the guiding part 7 and the plane where the access opening is located is the largest, in the direction perpendicular to the plane where the access opening is located, the second shaft 6 approaches the first shaft 5, effectively controlling the displacement amount of the door body 3 relative to the cabinet body 1 in the direction perpendicular to the plane where the access opening is located, so as to control the amount of movement of the door body 3 relative to the cabinet body 1 in the width direction and the amount of movement in the front-rear direction, in order to reduce the restriction of the space defined by the cabinet 2 on the movement of the door body 3, enabling the door body 3 to be opened to a larger angle.

[0187] Refer to Figure 6 , when the door body 3 is opened, the second shaft 6 moves relative to the guiding part 7, and the locus line of the first central axis Q moving relative to the guiding part 8 is denoted as the guiding locus line F.

[0188] In some embodiments of this application, the guiding locus line F includes a first guiding segment, and the first guiding segment extends from its end far from the door side wall 33 towards the side close to the door side wall 33 and far from the door front wall 31.

[0189] In some embodiments of this application, the distance between the end of the first guiding segment far from the door side wall 33 and the second central axis P first decreases and then increases.

[0190] In some embodiments of the present application, the guiding trajectory line F includes a second guiding segment, and the second guiding segment extends from one end thereof away from the door sidewall 33 towards the side close to the door sidewall 33 and the door front wall 31.

[0191] In some embodiments of the present application, the distance between one end of the second guiding segment away from the door sidewall 33 and the second central axis P first increases and then decreases.

[0192] In some embodiments of the present application, the guiding trajectory line F includes a connected first guiding segment and a second guiding segment. The guiding trajectory line F extends from one end of the first guiding segment away from the second guiding segment towards the side close to the door sidewall 33 and away from the door front wall 31 to H, and then extends from H towards the side close to the door sidewall 33 and the door front wall 31. To define the extending trend of the trajectory for the guiding portion to guide the movement of the central axis of the first axis, the extending trend of the guiding trajectory line is divided into two segments, and its trajectory extending trend is simple, improving the movement smoothness of the first axis relative to the guiding portion.

[0193] In some embodiments of the present application, the guiding trajectory line F is curved. The curved guiding trajectory line F bulges towards the side away from the door front wall 31. The guiding trajectory line F includes a first guiding segment and a second guiding segment connected to one end of the first guiding segment close to the door sidewall 33. Specifically, the guiding trajectory line F first extends from one end thereof away from the door sidewall 33 towards the side close to the door sidewall 33 and away from the door front wall 31, and then extends towards the side close to the door sidewall 33 and the door front wall 31.

[0194] In some embodiments of the present application, the distance between one end of the guiding trajectory line F away from the door sidewall 33 and the door front wall 31 is less than the distance between one end of the guiding trajectory line F close to the door sidewall 33 and the door front wall 31.

[0195] In some embodiments of the present application, the point on the guiding trajectory line F that is away from the door sidewall 33 and has the minimum distance from the door front wall 31 is denoted as the first guiding point K. The point on the guiding trajectory line F close to the door sidewall 33 and having the minimum distance from the door front wall 31 is denoted as the second guiding point J. The point on the guiding trajectory line F having the maximum distance from the door front wall 31 is denoted as the third guiding point H.

[0196] Corresponding to the guiding portion 8, the point on the guiding portion 8 that is away from the door sidewall 33 and has the minimum distance from the door front wall 31 is denoted as the first guiding boundary point K`. The point on the guiding portion 8 close to the door sidewall 33 and having the minimum distance from the door front wall 31 is denoted as the second guiding boundary point J`. The point on the guiding portion 8 having the maximum distance from the door front wall 31 is denoted as the third guiding boundary point H`.

[0197] Among them, the first guiding boundary point K`, the second guiding boundary point J`, and the third guiding boundary point H` are all located on the wall surface of the guiding part 8 (guiding groove) for cooperating with the first shaft 5. For example, when the guiding part 8 is a guiding groove, the above-mentioned first guiding boundary point K`, second guiding boundary point J`, and third guiding boundary point H` are all located on the inner wall of the guiding groove.

[0198] In some embodiments of the present application, the first guiding boundary point K` is located on the side of the starting guiding point K close to the front door wall 31. The straight line K`K where the first guiding boundary point K` and the first guiding point K are located is perpendicular to the front door wall 31. The distance between the first guiding boundary point K` and the first guiding point K is equal to the radius of the first shaft 5.

[0199] In some embodiments of the present application, the second guiding boundary point J` is located on the side of the second guiding point J close to the front door wall 31. The straight line J`J where the second guiding boundary point J` and the second guiding point J are located is perpendicular to the front door wall 31. The distance between the second guiding boundary point J` and the second guiding point J is equal to the radius of the first shaft 5.

[0200] In some embodiments of the present application, the third guiding boundary point H` is located on the side of the third guiding point H away from the front door wall 31. The straight line H`H where the third guiding boundary point H` and the third guiding point H are located is perpendicular to the front door wall 31. The distance between the third guiding boundary point H` and the third guiding point H is equal to the radius of the first shaft 5.

[0201] Above, when actually determining the positions of the first guiding point K, the second guiding point J, and the third guiding point H, the positions of the first guiding boundary point K`, the second guiding boundary point J`, the third guiding boundary point H`, and the radius of the first shaft 5 can be obtained by measurement tools, and then based on the relative relationship that the distance between the first guiding boundary point K` and the first guiding point K is equal to the radius of the first shaft 5, the distance between the second guiding boundary point J` and the second guiding point J is equal to the radius of the first shaft 5, and the distance between the third guiding boundary point H` and the third guiding point H is equal to the radius of the first shaft 5, the corresponding positions of the first guiding point K, the second guiding point J, and the third guiding point H are determined.

[0202] It should be noted that the "equal to" in the above that the distance between the first guiding boundary point K` and the first guiding point K is equal to the radius of the first shaft 5, the distance between the second guiding boundary point J` and the second guiding point J is equal to the radius of the first shaft 5, and the distance between the third guiding boundary point H` and the third guiding point H is equal to the radius of the first shaft 5 includes deviations caused by processing errors, etc.

[0203] It can be set that the above "equal to" includes the situation where the difference between the two equal objects belongs to any value in the range of 0 to 2 mm.

[0204] In some embodiments of the present application, when the door body 3 is in the closed state, the first central axis Q is located at the first guiding point K of the guiding track line F.

[0205] In some embodiments of the present application, under the limitation of the guiding portion 8, the guiding portion 7, the first shaft 5 and the second shaft 6, when the door body 3 is opened to the maximum angle, the first central axis Q is located at the second guiding point J of the guiding track line F.

[0206] It should be noted that on the premise that the front wall 31 of the door is perpendicular to the side wall 33 of the door, the direction perpendicular to the front wall 31 is the same as the direction parallel to the side wall 33 of the door. And the direction perpendicular to the side wall 33 of the door is the same as the direction parallel to the front wall 31 of the door.

[0207] In the case where the front wall 31 of the door is not perpendicular to the side wall 33 of the door, the direction perpendicular to the front wall 31 only represents the distance in the direction perpendicular to the front wall 31 and perpendicular to it, and there is no necessary connection with the parallel relationship of the side wall 33 of the door. Similarly, the direction perpendicular to the side wall 33 of the door only represents the distance in the direction perpendicular to the side wall 33 of the door and perpendicular to it, and there is no necessary connection with the parallel relationship of the front wall 31 of the door.

[0208] Refer to Figure 6 , in the plane projection parallel to the top wall of the box body 1, along the direction perpendicular to the side wall 33 of the door, the distance between the second central axis P and the third guiding point H is denoted as |PH|2. Among them, 0mm ≤ |PH|2 ≤ 5mm.

[0209] When 5mm < |PH|2, |PH|2 is too large. In the direction perpendicular to the side wall 33 of the door, the distance between the second shaft 6 and the third guiding point H on the guiding track line with the largest distance from the front wall 31 of the door is too large; during the movement of the door body 3 relative to the box body 1, when the first central axis Q moves to the third guiding point H, the distance between the second central axis and the first central axis in the direction perpendicular to the side wall 33 of the door is too large, and the inclination angle of the straight line where the first central axis and the second central axis are located relative to the plane where the pick-and-place opening is located is too large. At this time, the stability of the movement of the door body 3 relative to the box body 1 is poor.

[0210] In the present application, the setting of 0mm ≤ |PH|2 ≤ 5mm makes the second shaft 6 close to the third guiding point H on the guiding track line with the largest distance from the front wall 31 of the door in the direction perpendicular to the side wall 33 of the door; during the movement of the door body 3 relative to the box body 1, when the first central axis Q moves to the third guiding point H, the second central axis approaches the first central axis in the direction perpendicular to the side wall 33 of the door, effectively ensuring the stability of the movement of the door body 3 relative to the box body 1.

[0211] Refer to Figure 6, in the plane projection parallel to the top wall of the cabinet 1, along the direction perpendicular to the front door wall 31, the distance between the second central axis P and the first guiding point K is denoted as |PK|1. Wherein, 0mm ≤ |PK|1 ≤ 3mm.

[0212] When 3mm < |PK|1, |PK|1 is too large. In the direction perpendicular to the front door wall 31, the distance between the second central axis P and the first guiding point K, which is the farthest from the door side wall 33 on the guiding track line, is too large; during the movement of the door body 3 relative to the cabinet 1, when the first central axis Q reaches the first guiding point K, the distance between the second central axis and the first central axis in the direction perpendicular to the front door wall 31 is too large, and the inclination angle of the straight line where the first central axis and the second central axis are located relative to the plane where the picking and placing opening is located is too large. At this time, the stability of the movement of the door body 3 relative to the cabinet 1 is poor.

[0213] In this application, the setting of 0mm ≤ |PK|1 ≤ 3mm makes the second axis 6 close to the first guiding point K, which is the farthest from the door side wall 33 on the guiding track line, in the direction perpendicular to the front door wall 31; during the movement of the door body 3 relative to the cabinet 1, when the door body 3 is closed and the first central axis Q reaches the first guiding point K, the second central axis P is close to the first central axis in the direction perpendicular to the door side wall 33, effectively ensuring the stability of the movement of the door body 3 relative to the cabinet 1.

[0214] In some embodiments of this application, the first guiding point K is located on the side of the second central axis P away from the front door wall 31.

[0215] As Figures 7 - 20 shown, the movement of the first axis 5 along the guiding part 8 is equivalent to the movement of the first central axis Q along the guiding track line K. The movement of the second axis 6 along the guiding part 7 is equivalent to the movement of the second central axis P along the guiding track line S, so that the door body 3 can move a certain distance inward (in the direction close to the second body side wall) while rotating, so that the door body 3 does not interfere with the cabinet 2 and ensures the effective opening of the door body 3.

[0216] In some embodiments of this application, during the opening process of the door body 3, the first axis 5 moves relative to the guiding part 8 throughout the process, the second axis 6 moves relative to the guiding part 7 throughout the process, and the door body 3 rotates around a point that keeps dynamically changing relative to the cabinet 1 throughout the process.

[0217] In some embodiments of the present application, within the projection of the top wall plane of the cabinet 1, the line segment PQ is denoted as the axis center line segment PQ. The midpoint of the axis center line segment PQ is denoted as the axis center midpoint I. During the opening process of the door body 3, the first shaft 5 moves relative to the guiding portion 8 throughout the process, and the second shaft 6 moves relative to the guiding portion 7 throughout the process. The door body 3 rotates around a point (axis center midpoint I) that dynamically changes relative to the cabinet 1 throughout the process. Under the above settings, during the opening process of the door body 3, the first central axis Q moves relative to the guiding trajectory line F, and the second central axis P moves relative to the guiding trajectory line S. The door body 3 rotates with the axis center midpoint I as the instantaneous rotation center.

[0218] During the above opening process of the door body 3, the position of the first shaft 5 relative to the cabinet 1 remains unchanged, the position of the second shaft 6 relative to the cabinet 1 continuously changes, the position and length of the axis center line segment PQ relative to the cabinet 1 continuously change, the position of the axis center midpoint I relative to the cabinet 1 continuously changes, and the rotation center axis of the rotation of the door body 3 relative to the cabinet 1 continuously changes.

[0219] The guiding trajectory line F includes a second guiding point J at one end close to the door side wall 33 and a first guiding point K at one end far from the door side wall 33. The guiding trajectory line F extends from the first guiding point K first to the side close to the door side wall 33 and away from the front door wall 31 to the third guiding point H, and then extends from the third guiding point H to the side close to the door side wall 33 and the front door wall 31 to the second guiding point J.

[0220] In some embodiments of the present application, the guiding trajectory line F is a smooth convex curve to make the movement of the first shaft 5 relative to the guiding portion 8 more smooth.

[0221] As Figures 7 - 20 shown, taking the first shaft 5 and the guiding portion 7 (cabinet 1) provided on the cabinet 1 as static reference objects, the movement of the second shaft 6 along the guiding portion 7 is equivalent to the movement of the second central axis P along the guiding trajectory line S, and the movement of the guiding portion 8 relative to the first shaft 5 is equivalent to the movement of the guiding trajectory line F passing through the first central axis Q, so that the door body 3 can move a certain distance inward (in the direction close to the second body side wall) while rotating, thereby compensating for the outward displacement of the first side edge W caused by the simple rotation of the door body 3 and effectively avoiding interference between the door body 3 and the cabinet 2 when the door body 3 is opened.

[0222] The movement of the door body 3 relative to the cabinet 1 is equivalent to the relative movement between the two in the plane of the top wall of the cabinet 1 (or in a plane parallel to the top wall of the cabinet 1); that is, the movement of the door body 3 relative to the cabinet 1 is a relative movement in a two-dimensional plane. In the plane of the top wall of the cabinet 1, the movement of the guiding portion 8 located on the door body 3 relative to the first shaft 5 provided on the cabinet 1 (or the movement of the second shaft 6 located on the door body 3 relative to the guiding portion 7 provided on the cabinet 1) is equivalent to the movement of the door body 3 relative to the hinge plate 4, and is also equivalent to the movement of the door body 3 relative to the cabinet 1.

[0223] In the plane of the top wall of the box body 1, on the side of the box body 1 close to the door body 3, a displacement coordinate system AOB is established. Specifically, in the displacement coordinate system AOB, OB is perpendicular to the plane where the pick-and-place opening is located, and OA is parallel to the plane where the pick-and-place opening is located (or perpendicular to the side wall of the first body). In the displacement coordinate system AOB, the direction from the side wall of the first body to the side wall of the second body is defined as the positive direction of the A axis, and the direction from the plane where the pick-and-place opening is located to the front wall 31 in front of the door body 3 when the door body 3 is closed (from the back to the front) is defined as the positive direction of the B axis.

[0224] It should be noted that during the opening process of the door body 3, the displacement coordinate system AOB remains stationary relative to the box body 1 and does not move with the opening of the door body 3.

[0225] During the movement of the door body 3 relative to the box body 1, the door body 3 has a translational movement while rotating. Among them, the translational movement of the door body 3 is decomposed into a first-direction movement perpendicular to the side wall of the first body (along the A axis) and a second-direction movement perpendicular to the plane where the pick-and-place opening is located (along the B axis). Among them, the displacement amount in the first direction perpendicular to the side wall of the first body (along the A axis) is denoted as the first-direction displacement Among them, the first-direction displacement When it is, it has a displacement moving inward; the first-direction displacement When it is, it has a displacement moving outward. Among them, the first-direction displacement The modulus of is denoted as

[0226] The displacement amount in the second direction perpendicular to the plane where the pick-and-place opening is located (along the B axis) is denoted as the second-direction displacement Among them, the second-direction displacement When it is, it has a displacement moving forward; the second-direction displacement When it is, it has a displacement moving backward. Among them, the second-direction displacement The modulus of is denoted as

[0227] In some embodiments of the present application, when the opening angle of the door body 3 is (when the door body is in the closed state), the first shaft 5 is located at the end of the guiding part 8 far from the door side wall 33, and the second shaft 6 is located at the end of the guiding part 7 close to the side wall of the first body. The above limits the position of the first shaft relative to the guiding part and the position of the second shaft relative to the guiding part when the door body is closed, so as to limit the moving trend of the first shaft relative to the guiding part and the second shaft relative to the guiding part in the first stage of the opening of the door body, thereby limiting the translational trend of the first stage of the opening of the door body relative to the box body, so as to avoid interference between the door body and the cabinet and avoid or reduce the extrusion of the door seal by the door body.

[0228] In some embodiments of the present application, such as Figure 7 、Figure 8 , Figures 13 - 16 As shown, under the limitation of the aforementioned guiding portion 8 and the first shaft 5, and the guiding portion 7 and the second shaft 6, the door body 3 has a first stage during the opening process. The specific first stage is as follows:

[0229] In some embodiments of the present application, the guiding trajectory line S includes a starting guiding point P0 close to the side wall of the first body and a first guiding point P1 located on the side of the starting guiding point P0 away from the side wall of the first body.

[0230] The first guiding point P1 is located on the side of the starting guiding point P0 away from the plane where the pick-and-place opening is located.

[0231] The guiding trajectory line S extends from the starting guiding point P0 in a direction away from the side wall of the first body and the plane where the pick-and-place opening is located to the first guiding point P1.

[0232] When the opening angle of the door body 3 is , the second central axis P is located at the starting guiding point P0 of the guiding trajectory line S.

[0233] When the opening angle of the door body 3 is , the second central axis P is located at the first guiding point P1 of the guiding trajectory line S. At this time, the second central axis P is located at the position on the guiding trajectory line S with the maximum distance from the plane where the pick-and-place opening is located. Among them, the first guiding point P1 is located on the side of the starting guiding point P0 away from the side wall of the first body and the plane where the pick-and-place opening is located.

[0234] When the door body 3 is opened from to , the second central axis P moves from the starting guiding point P0 to the first guiding point P1 relative to the guiding trajectory line S (the box body 1 or the hinge plate 4).

[0235] When the door body 3 is opened from to , the second central axis P moves relative to the guiding trajectory line S (the box body 1 or the hinge plate 4) to the side away from the side wall of the first body and the plane where the pick-and-place opening is located. That is, the second shaft 6 moves relative to the guiding portion 8 to the side away from the side wall of the first body and the plane where the pick-and-place opening is located.

[0236] When the door body 3 is opened from to , the first central axis Q moves relative to the guiding trajectory line F (the door body 3) to the side close to the door side wall 33 and away from the door front wall 31. That is, the first shaft 5 moves relative to the guiding portion 8 to the side close to the door side wall 33 and away from the door front wall 31.

[0237] When the opening angle of the door body 3 is , the guiding trajectory line F passes through the first central axis Q, and the first central axis Q is located at the first guiding point K of the guiding trajectory line F. That is, when the opening angle of the door body 3 is When the first guiding point K of the guiding track line F coincides with the first central axis Q. At this time, the opening angle of the door body 3 is When the first guiding point K of the guiding track line F is at the starting guiding position K0 relative to the box body 1; the second guiding point J of the guiding track line F is at the starting guiding point J0 relative to the box body 1.

[0238] The opening angle of the door body 3 is When the guiding track line F passes through the first central axis Q, the first guiding point K of the guiding track line F is at the first guiding position K1 relative to the box body 1; the second guiding point J of the guiding track line F is at the second guiding point J1 relative to the box body 1. Among them, the first guiding position K1 is on the side of the starting guiding position K0 away from the first body side wall and the plane where the picking and placing opening is located. The second guiding point J1 is on the side of the starting guiding point J0 away from the first body side wall and close to the plane where the picking and placing opening is located.

[0239] The door body 3 is from opened to In the process, the guiding track line F passes through the first central axis Q and moves relative to the first central axis Q (the box body 1 or the hinge plate 4). In the above process of the door body 3 being from opened to In the process, the first guiding point K of the guiding track line F gradually moves away from the first central axis Q starting from the position where it coincides with the first central axis Q, and the second guiding point J gradually approaches the first central axis Q. In the above process of the door body 3 being from opened to In the process, the first guiding point K moves to the side away from the first body side wall and the plane where the picking and placing opening is located, and the second guiding point J moves to the side away from the first body side wall and close to the plane where the picking and placing opening is located.

[0240] The door body 3 is from opened to In the process, the second central axis P gradually approaches the first central axis Q.

[0241] The opening angle of the door body 3 is When the midpoint of the axis I is at the starting midpoint I0 relative to the box body 1.

[0242] The opening angle of the door body 3 is When the midpoint of the axis I is at the first midpoint I1 relative to the box body 1.

[0243] In some embodiments of the present application, the first midpoint I1 is on the side of the starting midpoint I0 away from the first body side wall. The door body 3 is from opened to In the process, the midpoint of the axis I moves relative to the box body 1 to the side away from the first body side wall.

[0244] With the box body 1 (hinge plate 4) as a reference, the door body 3 is opened to During this process, the displacement in the first direction The door body 3 has a tendency to move inward to compensate for the displacement of the first side edge W moving outward caused by the simple rotation of the door body 3, so as to prevent the first side edge W from colliding with the cabinet 2 and causing the door body 3 to be unable to open further; in addition, the door body 3 moves inward to reduce the limitation of the space defined by the cabinet 2 on the maximum opening angle of the door body 3 therein, so that the door body 3 of the refrigerator 100 placed in the cabinet 2 can open at a larger angle, facilitating the user to take and place items.

[0245] In some embodiments of the present application, the first midpoint I1 is located on the side of the starting midpoint I0 away from the plane where the access opening is located. The door body 3 is opened to During this process, the axis midpoint I moves relative to the box body 1 to the side away from the plane where the access opening is located.

[0246] With the box body 1 (hinge plate 4) as a reference, the door body 3 is opened to During this process, the displacement in the second direction The door body 3 has a tendency to move forward so that the door body 3 breaks away from the space defined by the cabinet 2 and reduces the limitation of the space defined by the cabinet 2 on the maximum opening angle of the door body 3 therein.

[0247] In some embodiments of the present application, the first midpoint I1 is located on the side of the starting midpoint I0 away from the first body side wall and the plane where the access opening is located. The door body 3 is opened to During this process, the axis midpoint I moves relative to the box body 1 to the side away from the first body side wall and the plane where the access opening is located.

[0248] In some embodiments of the present application, with the box body 1 (hinge plate 4) as a reference, the door body 3 is opened to During this process, the displacement in the first direction The displacement in the second direction When the door body 3 is opened to During this process, the door body 3 has a tendency to move inward and forward while rotating to open the access opening.

[0249] In some embodiments of the present application, when the door body 3 is opened to During this process, That is, when the door body 3 is opened to During the process, the translational movement of the door body 3 mainly moves inward, supplemented by moving forward, mainly compensating for the displacement of the first side edge W caused by the simple rotation of the door body 3 outward, and supplemented by effectively reducing the limitation of the space defined by the cabinet 2 on the maximum opening angle of the door body 3 therein, so as to facilitate the door body 3 to open to a larger angle within the space defined by the cabinet 2.

[0250] In some embodiments of the present application, the starting guiding point P0 is the first limit guiding point P1`. That is, when the door body 3 is opened to , the second central axis P is located at the position on the guiding track line S where the distance from the first body side wall is the smallest (at the first limit guiding point P1` / starting guiding point P0).

[0251] In some embodiments of the present application, the starting guiding point P0 is located on the side of the first limit guiding point P1` away from the first body side wall and the plane where the access opening is located. That is, when the door body 3 is opened to , the position of the second central axis P relative to the guiding track line S has a certain distance from the first limit guiding point P1`. Correspondingly, when the door body 3 is opened to , the second shaft 6 is located at the position of the guiding part 7 close to the first body side wall, and there is a gap between the second shaft 6 and the end of the guiding part 7 close to the first body side wall. When the guiding part 7 is set as a guiding groove, when the door body 3 is opened to , there is a gap between the second shaft 6 and the end wall of the guiding groove close to the first body side wall. The above settings enable the door body 3 to continue to move along the closing direction, and the second shaft 6 can continue to move towards the direction close to the first body side wall relative to the guiding part 7 (guiding groove), so that the door body 3 can continue to close.

[0252] In some embodiments of the present application, the door body 3 is in the closed state. When, the second central axis P is located at the starting guiding point P0 of the guiding track line S. The starting guiding point P0 is located on the side of the first limit guiding point P1` away from the first body side wall and the plane where the access opening is located. There is a gap between the second shaft 6 and the end of the guiding part 7 (guiding groove) close to the first body side wall, enabling the door body 3 to continue to move along the closing direction from the closed state, so as to ensure that when the door body 3 is slammed into the box body 1, the impact between the second shaft 6 and the end of the guiding part 7 close to the first body side wall is prevented.

[0253] In some embodiments of the present application,

[0254] In some embodiments of the present application, the door body 3 is in the closed state. Among them, the door body 3 is closed to When there is a gap between the second shaft 6 and the end of the guiding portion 7 close to the side wall of the first body, the door body 3 can continue to move in the closing direction from the closed state until the door body 3 is closed to so that when the door body 3 is in a closed state relative to the box body 1, it is in a negative angle state, and the door body 3 presses the door seal strip to ensure the sealing performance between the door body 3 and the box body 1.

[0255] In some embodiments of the present application,

[0256] such as Figure 8 、 Figure 9 、 Figure 13 、 Figure 14 、 Figure 15 、 Figure 17 As shown, under the limitation of the foregoing guiding portion 8 and the first shaft 5, and the guiding portion 7 and the second shaft 6, the opening process of the door body 3 has a second stage. The second stage is specifically as follows:

[0258] The second guiding point P2 is located on the side of the first guiding point P1 close to the plane where the access opening is located.

[0259] The guiding track line S extends from the first guiding point P1 in a direction away from the side wall of the first body and close to the plane where the access opening is located to the second guiding point P2.

[0260] When the opening angle of the door body 3 is , the second central axis P is located at the first guiding point P1 of the guiding track line S.

[0261] When the opening angle of the door body 3 is , the second central axis P is located at the second guiding point P2 of the guiding track line S. The second guiding point P2 is located on the side of the first guiding point P1 away from the side wall of the first body and close to the plane where the access opening is located.

[0262] When the door body 3 is opened from to , the second central axis P moves from the first guiding point P1 to the second guiding point P2 relative to the guiding track line S (the box body 1 or the hinge plate 4).

[0263] When the door body 3 is opened from to , the second central axis P moves relative to the guiding track line S (the box body 1 or the hinge plate 4) to the side away from the side wall of the first body and close to the plane where the access opening is located. That is, the second shaft 6 moves relative to the guiding portion 8 to the side away from the side wall of the first body and close to the plane where the access opening is located.

[0264] During the process that the door body 3 is opened from to the first central axis Q moves towards the side close to the door side wall 33 and away from the front door wall 31 relative to the guiding track line F (door body 3). That is, the first axis 5 moves towards the side close to the door side wall 33 and away from the front door wall 31 relative to the guiding part 8.

[0265] When the opening angle of the door body 3 is the guiding track line F passes through the first central axis Q, and the first guiding point K of the guiding track line F is located at the first guiding position K1 relative to the box body 1; the second guiding point J of the guiding track line F is located at the second guiding point J1 relative to the box body 1.

[0266] When the opening angle of the door body 3 is the guiding track line F passes through the first central axis Q, and the first guiding point K of the guiding track line F is located at the second guiding position K2 relative to the box body 1; the second guiding point J of the guiding track line F is located at the second guiding point J2 relative to the box body 1. Among them, the second guiding position K2 is located at the side close to the first body side wall and away from the plane where the picking and placing opening is located with respect to the first guiding position K1. The second guiding point J2 is located at the side away from the first body side wall and close to the plane where the picking and placing opening is located with respect to the second guiding point J1.

[0267] During the process that the door body 3 is opened from to the guiding track line F passes through the first central axis Q and moves relative to the first central axis Q (box body 1 or hinge plate 4). During the above process that the door body 3 is opened from to the first guiding point K of the guiding track line F gradually moves away from the first central axis Q, and the second guiding point J gradually moves closer to the first central axis Q. During the above process that the door body 3 is opened from to the first guiding point K moves towards the side close to the first body side wall and away from the plane where the picking and placing opening is located, and the second guiding point J moves towards the side away from the first body side wall and close to the plane where the picking and placing opening is located.

[0268] During the process that the door body 3 is opened from to the second central axis P gradually moves closer to the first central axis Q.

[0269] When the opening angle of the door body 3 is the midpoint of the axis I is located at the first midpoint I1 relative to the box body 1.

[0270] When the opening angle of the door body 3 is the midpoint of the axis I is located at the second midpoint I2 relative to the box body 1.

[0271] In some embodiments of the present application, the second midpoint I2 is located on the side of the first midpoint I1 away from the first body sidewall.

[0272] The door body 3 is composed of When opening to During this process, the axial midpoint I moves relative to the cabinet 1 to the side away from the first body sidewall.

[0273] In some embodiments of the present application, the door body 3 is composed of When opening to During this process, the displacement in the first direction The door body 3 has a tendency to move inward to compensate for the displacement of the first side edge W moving outward caused by the simple rotation of the door body 3, avoiding collisions between the first side edge W and the cabinet 2 that prevent the door body 3 from continuing to open; in addition, the door body 3 moves inward to reduce the limitation of the space defined by the cabinet 2 on the maximum opening angle of the door body 3 within it, so that the door body 3 of the refrigerator 100 placed in the cabinet 2 can be opened at a larger angle, facilitating users to pick up and place items.

[0274] In some embodiments of the present application, the second midpoint I2 is located on the side of the first midpoint I1 close to the plane where the access opening is located. The door body 3 is composed of When opening to During this process, the axial midpoint I moves relative to the cabinet 1 to the side close to the plane where the access opening is located.

[0275] Taking the cabinet 1 (hinge plate 4) as a reference, when the door body 3 is opened from to During this process, the displacement in the second direction The door body 3 has a tendency to move backward.

[0276] In some embodiments of the present application, the second midpoint I2 is located on the side of the first midpoint I1 away from the first body sidewall and close to the plane where the access opening is located. The door body 3 is composed of When opening to During this process, the axial midpoint I moves relative to the cabinet 1 to the side away from the first body sidewall and close to the plane where the access opening is located.

[0277] In some embodiments of the present application, taking the cabinet 1 (hinge plate 4) as a reference, when the door body 3 is opened from to During this process, the displacement in the first direction The displacement in the second direction When the door body 3 is opened from to During this process, the door body 3 has a tendency to move inward and backward while rotating to open the access opening.

[0278] In some embodiments of the present application, the door body 3 is composed of Open to In the process, That is, the door body 3 is composed of Open to During the process, the translational movement of the door body 3 is mainly inward movement, mainly to compensate for the outward displacement of the first side edge W caused by the simple rotation of the door body 3, effectively avoiding the interference of the first side edge W with the cabinet 2; at the same time, it effectively reduces the restriction of the space defined by the cabinet 2 on the maximum opening angle of the door body 3 therein, so as to facilitate the door body 3 to be opened to a larger angle within the space defined by the cabinet 2.

[0279] In some embodiments of the present application, the door body 3 is composed of Open to The second direction displacement mode of the process No more than 3 doors Open to The second direction displacement mode of the process That is, the door body 3 is composed of Open to The amount of displacement moving backward during the process is not greater than Open to The above arrangement makes the door body 3 move forward. Open to During the process, the opening angle relative to the door body 3 is The state has an overall inward and forward translational displacement to compensate for the outward displacement of the first side edge W caused by the simple rotation of the door body 3, effectively avoiding the interference of the first side edge W with the cabinet 2; at the same time, efficiently reducing the restriction of the space defined by the cabinet 2 on the maximum angle that the door body 3 therein can open.

[0280] In some embodiments of the present application, the refrigerator includes a locking assembly. The locking assembly includes a first matching portion and a second matching portion that match each other, and the first matching portion and the second matching portion match each other to achieve locking and unlocking of the door body 3 and the box body 1. The first matching portion is arranged on the box body 1 near the lower end of the door body 3, and the second matching portion is arranged at the lower end of the door body 3 to match with the first matching portion.

[0281] In some embodiments of the present application, the first matching portion is located on a side of the first hinge away from the first body side wall. The second matching portion is located on a side of the second hinge away from the door side wall 33. The second matching portion is used to match the first matching portion to achieve locking and unlocking of the door body 3 and the box body 1.

[0282] In some embodiments of the present application, the locking process of the door body 3 and the box body 1 is as follows:

[0283] When the door body 3 closes from the open state, the door body 3 gradually closes. As the door body 3 rotates and closes, the second engaging portion gradually approaches the first engaging portion.

[0284] When the door body 3 closes to the angle G B0 the second engaging portion contacts the first engaging portion. As the door body 3 continues to close, the first engaging portion and the second engaging portion interact with each other, and the second engaging portion undergoes elastic deformation. Under the combined action of the external force and the acting force of the first engaging portion, the second engaging portion and the first engaging portion gradually approach each other, and the elastic deformation amount of the second engaging portion gradually increases.

[0285] When the door body 3 closes to the angle G B2 the elastic deformation amount of the second engaging portion reaches the maximum deformation amount during the closing process of the door body 3.

[0286] When the door body 3 closes to the angle G B2 and then continues to move in the closing direction, the elastic energy stored in the elastic deformation of the second engaging portion is released, the second engaging portion returns to the relaxed state, and drives the door body 3 to automatically close in place. When the door body 3 reaches the closed state, the second engaging portion and the first engaging portion are locked, realizing the locking of the door body 3 and the box body 1.

[0287] Above, G B0 > G B2 .

[0288] In summary, it can be seen that during the process of the door body 3 closing from the angle G B0 to the angle G B2 the deformation amount of the elastic deformation of the second engaging portion continuously increases.

[0289] When the door body 3 closes to the angle G B2 the elastic deformation amount of the second engaging portion reaches the maximum deformation amount during the closing process of the door body 3.

[0290] During the process of the door body 3 from the angle G B2 to the closed state, the elastic force of the second engaging portion is released, and the door body 3 automatically closes.

[0291] That is, under the structural settings of the first engaging portion and the second engaging portion, the door body 3 has the characteristic of automatically closing during the process of the door body 3 from the angle G B2 to the closed state. Under the setting of the locking component, the door body 3 can automatically close in place, so that the door body 3 and the box body 1 are hermetically matched to avoid cold leakage.

[0292] In some embodiments of the present application, the unlocking process of the door body 3 and the box body 1 is as follows:

[0293] When the door body 3 is opened from the closed state (or when the door body 3 is opened from the angle G0), the door body 3 is gradually opened. As the door body 3 rotates and opens, the second engaging portion and the first engaging portion interact with each other, and the second engaging portion undergoes elastic deformation.

[0294] As the door body 3 continues to open, the amount of elastic deformation of the second engaging portion gradually increases; during the process in which the second engaging portion continuously undergoes elastic deformation as described above, a relatively large external force needs to be applied to continue opening the door body, so that the first engaging portion and the second engaging portion are continuously separated.

[0295] When the door body 3 is opened to the angle G B1 , the amount of elastic deformation of the second engaging portion reaches the maximum deformation amount during the opening process of the door body 3.

[0296] When the door body 3 is opened to reach the angle G B1 and then continues to move in the opening direction, the elastic energy stored by the elastic deformation of the second engaging portion is released, and the second engaging portion returns to the relaxed state. The second engaging portion is separated from the first engaging portion, and the door body 3 is separated from the box body 1.

[0297] In some embodiments of the present application, when the door body 3 is closed to the angle G0, the second engaging portion and the first engaging portion are locked.

[0298] The door body 3 is opened from the angle G0, the first engaging portion and the second engaging portion interact with each other, and the second engaging portion undergoes elastic deformation;

[0299] When the door body is opened to the angle G B1 , the elastic energy stored by the elastic deformation of the second engaging portion is released.

[0300] That is, during the process in which the door body 3 is opened from the angle G0 to the angle G B1 , the amount of deformation of the elastic deformation of the second engaging portion continuously increases. When the door body 3 is opened to the angle G B1 , the amount of elastic deformation of the second engaging portion reaches the maximum deformation amount during the closing process of the door body 3. During the process in which the door body 3 continues to open from the angle G B1 , the elastic force of the second engaging portion is released.

[0301] In some embodiments of the present application, G B2 = G B1 .

[0302] In some embodiments of the present application, the second engaging portion is provided on the side of the second shaft 6 and the guiding portion 8 away from the door side wall 33. The second engaging portion is provided as a locking hook. Specifically, the locking hook first extends to the side away from the door side wall 33, and then bends toward the side close to the door rear wall 32 and the door side wall 33, and the opening of the locking hook faces the door side wall 33. Among them, the free end of the locking hook is located on the side close to the door rear wall 32.

[0303] In some embodiments of the present application, the first engaging portion is disposed on a side of the hinge plate 4 away from the side wall of the first body. The first engaging portion is configured as a stop portion. The stop portion has a hooking gap on a side close to the box body 1.

[0304] When the door body 3 is in the closed state (or G0), the free end of the locking hook is received in the hooking gap, the stop portion is located inside the locking hook, and the locking hook on the door body 3 hooks the stop portion on the hinge plate 4, thereby locking the door body 3 and the box body 1, and preventing cold air leakage due to improper closing of the door body 3, which affects the refrigeration / freezing effect of the refrigerator 100. When the door body 3 is opened, the locking hook deforms under force and overcomes the blocking of the stop portion, thereby disengaging from the stop portion to unlock the door body 3 and the box body 1.

[0305] When the door body 3 is opened from the closed state (or G0), under the action of an external force, the door body 3 gradually opens. As the door body 3 rotates and opens, the free end of the locking hook interacts with the stop portion, and the locking hook undergoes elastic deformation.

[0306] Then, under the action of an external force, the door body 3 continues to open, the stop portion interacts with the locking hook, the locking hook undergoes elastic deformation, and under the combined action of the external force and the acting force of the stop portion, the locking hook gradually disengages from the hooking gap (simultaneously the stop portion disengages from the locking hook).

[0307] When the door body 3 is opened to the angle G B1 the elastic deformation amount of the locking hook reaches the maximum deformation amount during the closing process of the door body 3.

[0308] When the door body 3 is opened to reach the angle G B1 and then continues to open, the elastic energy stored in the elastic deformation of the locking hook is gradually released, the locking hook returns to the relaxed state, and drives the free end of the locking hook to further disengage from the hooking gap, the locking hook is separated from the stop portion, and the door body 3 is separated from the box body 1.

[0309] In some embodiments of the present application, during the process in which the first engaging portion and the second engaging portion are unlocked from the locked state and the elastic deformation amount of the second engaging portion is continuously increasing, the displacement in the first direction the displacement in the second direction As described above, during the unlocking of the first engaging portion and the second engaging portion and the continuous increase of the elastic deformation amount of the second engaging portion, the door body 3 has a tendency to move inward and backward, which accelerates the separation of the first engaging portion and the second engaging portion, reduces the acting force of the first engaging portion on the second engaging portion, reduces the elastic deformation amount of the second engaging portion, facilitates the unlocking of the first engaging portion and the second engaging portion, and is conducive to the unlocking of the door body and the box body.

[0310] In some embodiments of the present application, during the process in which the first engaging portion and the second engaging portion are unlocked from the locked state and the elastic deformation amount of the second engaging portion continuously increases, the midpoint I of the axis moves toward the side close to the side wall of the second body and the plane where the access opening is located. As above, during the process in which the first engaging portion and the second engaging portion are unlocked and the elastic deformation amount of the second engaging portion continuously increases, the door body 3 has a tendency to move inward and backward, which accelerates the separation of the first engaging portion and the second engaging portion, reduces the acting force of the first engaging portion on the second engaging portion, reduces the elastic deformation amount of the second engaging portion, facilitates the unlocking of the first engaging portion and the second engaging portion, and is conducive to the unlocking of the door body and the box body.

[0311] It should be noted that the process in which the first engaging portion and the second engaging portion are unlocked from the locked state and the elastic deformation amount of the second engaging portion continuously increases includes the moment when the elastic deformation amount of the second engaging portion reaches the maximum.

[0312] In some embodiments of the present application, the door body 3 is opened from the locked state of the first engaging portion and the second engaging portion. As the door body 3 is opened, the second engaging portion undergoes elastic deformation; during the process in which the elastic energy stored in the elastic deformation of the second engaging portion is gradually released, the second shaft 6 moves relative to the guiding portion 7 to a position where the distance from it to the plane of the access opening is the largest.

[0313] It should be noted that during the process in which the elastic energy stored in the elastic deformation of the second engaging portion is gradually released, it includes the moment when the elastic deformation amount of the second engaging portion reaches the maximum.

[0314] As above, during the unlocking process of the first engaging portion and the second engaging portion, after the elastic deformation amount of the second engaging portion reaches the maximum, the mutual acting force between the first engaging portion and the second engaging portion rapidly decreases, and the external force required also rapidly decreases. However, the external force applied by the user cannot be rapidly reduced or the inertial force of the opening of the door body still exists, resulting in a rapid increase in the relative movement speed of the first engaging portion and the second engaging portion; and at this time, the second shaft 6 moves relative to the guiding portion 7 to a position where the distance from it to the plane of the access opening is the largest. Based on the guiding trajectory line S being convex toward the side away from the plane where the access opening is located, there is resistance for the second shaft 6 to move relative to the guiding portion 7 toward the side close to or away from the side wall of the first body. The second shaft 6 located at the position where the distance from it to the plane of the access opening is the largest on the guiding portion 7 is in a relatively stable state relative to the guiding portion 7, and the movement of the door body 3 relative to the box body 1 is in a stable state, so that the unlocking process of the first engaging portion and the second engaging portion is more stable and smooth.

[0315] In some embodiments of the present application, when the door body 3 is closed to an angle G0, the second engaging portion is locked with the first engaging portion.

[0316] The door body 3 is opened from the angle G0, the first engaging portion and the second engaging portion interact with each other, and the second engaging portion undergoes elastic deformation.

[0317] When the door body 3 is opened to an angle G B1 After that, the elastic energy stored in the elastic deformation of the second engaging portion is released.

[0318] When the door body 3 is opened from the angle G0 to the angle G1, the second shaft 6 moves relative to the guiding portion 7 toward the side close to the side wall of the first body and away from the pick-and-place opening;

[0319] When the door body 3 is opened from the angle G1 to the angle G2, the second shaft 6 moves relative to the guiding portion 7 toward the side close to the plane where the side wall of the first body and the pick-and-place opening are located; wherein, G0 < G B1 < G1 < G2, or G0 < G1 < G B1 < G2;

[0320] Wherein, the absolute value of the difference between G1 and G B1 is denoted as |G1 - G B1 |, 0° ≤ |G1 - G B1 | ≤ 3°. When the opening angle of the door body 3 is G1, the second central axis P is located at the first guiding point P1 on the guiding track line S with the maximum distance from the plane where the pick-and-place opening is located. Correspondingly, the second shaft 6 is located at the position on the guiding portion 7 with the maximum distance from the plane where the pick-and-place opening is located. Based on the fact that the guiding track line S bulges toward the side away from the plane where the pick-and-place opening is located, there is a resistance for the second shaft 6 to move relative to the guiding portion 7 toward the side close to the side wall of the first body or away from the side wall of the first body. The second shaft 6 located at the position on the guiding portion 7 with the maximum distance from the plane of the pick-and-place opening is in a relatively stable state relative to the guiding portion 7, and the movement of the door body 3 relative to the box body 1 is in a stable state.

[0321] When the door body 3 is opened, when the first engaging portion and the second engaging portion are unlocked, a relatively large external force needs to be applied first so that the second engaging portion undergoes elastic deformation under the action of the first engaging portion. After the elastic deformation amount of the second engaging portion reaches the maximum, the mutual acting force between the first engaging portion and the second engaging portion rapidly decreases, and the external force required also rapidly decreases. However, the external force applied by the user cannot be rapidly decreased or the inertial force when the door body 3 is opened still exists, resulting in a rapid increase in the relative movement speed of the first engaging portion and the second engaging portion, and the unlocking process of the first engaging portion and the second engaging portion is unstable, resulting in unstable opening of the door body 3.

[0322] The above setting of 0° ≤ |G1 - G B1 | ≤ 3° enables the second shaft 6 to maintain a stable movement relative to the guiding portion 7 when the first engaging portion and the second engaging portion are unlocked, so that the unlocking process of the first engaging portion and the second engaging portion is more stable and smooth.

[0323] |G1 - G B1 | > 3°, the maximum deformation angle G when the first engaging portion and the second engaging portion are unlocked B1When the difference between the angle G1 at which the second shaft 6 is stable relative to the guiding portion 7 is too large, the unlocking process of the first engaging portion and the second engaging portion cannot effectively correspond to the process in which the second shaft 6 maintains stable movement relative to the guiding portion 7, and the cooperation between the second shaft 6 and the guiding portion 7 cannot play a role in stabilizing the unlocking process of the first engaging portion and the second engaging portion.

[0324] In some embodiments of the present application,

[0325] In some embodiments of the present application, the second guiding point P2 is the second limit guiding point P2`. That is, when the door body 3 is opened to the second central axis P is at the position on the guiding track line S that is farthest from the first body side wall (the second limit guiding point P2` / the second guiding point P2).

[0326] In some embodiments of the present application, the second limit guiding point P2` is located on the side of the second guiding point P2 that is away from the first body side wall and close to the plane where the pick-and-place opening is located. That is, when the door body 3 is opened to the position of the second central axis P relative to the guiding track line S has a certain distance from the second limit guiding point P2`. Correspondingly, when the door body 3 is opened to the second shaft 6 is at the position of the guiding portion 7 that is away from the first body side wall, and there is a gap between the second shaft 6 and the end of the guiding portion 7 that is away from the first body side wall. When the guiding portion 7 is provided as a guiding groove, when the door body 3 is opened to there is a gap between the second shaft 6 and the end of the guiding groove that is away from the first body side wall. With the above settings, during the opening process of the door body 3, the second shaft 6 does not collide with the end of the guiding portion 7 that is away from the first body side wall, so as to avoid the impact of the second shaft 6 and the end of the guiding portion 7 that is away from the first body side wall and prevent the second shaft 6 from being damaged.

[0327] In some embodiments of the present application,

[0328] As Figure 9 、 Figure 10 、 Figure 13 、 Figure 14 、 Figure 15 、 Figure 18 shown, under the limitation of the foregoing guiding portion 8 and the first shaft 5, and the guiding portion 7 and the second shaft 6, the opening process of the door body 3 has a third stage. The third stage is specifically as follows:

[0329] In some embodiments of the present application, the guiding track line S includes a second guiding point P2 and a third guiding point P3 located on the side of the second guiding point P2 that is close to the first body side wall.

[0330] The third guiding point P3 is located on the side of the second guiding point P2 that is away from the plane where the pick-and-place opening is located.

[0331] The guiding trajectory line S extends from the second guiding point P2 towards the side wall of the first body and away from the plane where the pick-and-place opening is located to the third guiding point P3.

[0332] In some embodiments of the present application, in combination with the settings of the first stage and the second stage, the guiding trajectory line S first extends from the starting guiding point P0 in a direction away from the side wall of the first body and the plane where the pick-and-place opening is located to the first guiding point P1, and then extends in a direction away from the side wall of the first body and towards the plane where the pick-and-place opening is located to the second guiding point P2. During the extension process of the above guiding trajectory line S, the guiding trajectory line S passes through the third guiding point P3. That is, the third guiding point P3 is located on the guiding trajectory line S and on the side of the second guiding point P2 close to the side wall of the first body.

[0333] In some embodiments of the present application, the third guiding point P3 is located on the trajectory segment of the guiding trajectory line S extending from the first guiding point P1 to the second guiding point P2.

[0334] In some embodiments of the present application, the third guiding point P3 is located on the side of the first guiding point P1 away from the side wall of the first body and close to the plane where the pick-and-place opening is located.

[0335] In some embodiments of the present application, the third guiding point P3 coincides with the first guiding point P1. That is, when the opening angle of the door body 3 is the second shaft 6 moves relative to the guiding part 7 to the position of the second shaft 6 relative to the guiding part 7 when the opening angle of the door body 3 is

[0336] When the opening angle of the door body 3 is the second central axis P is located at the second guiding point P2 of the guiding trajectory line S.

[0337] When the opening angle of the door body 3 is the second central axis P is located at the third guiding point P3 of the guiding trajectory line S. The third guiding point P3 is located on the side of the second guiding point P2 close to the side wall of the first body and away from the plane where the pick-and-place opening is located.

[0338] When the door body 3 is opened from to the second central axis P moves relative to the guiding trajectory line S (the box body 1 or the hinge plate 4) from the second guiding point P2 to the third guiding point P3.

[0339] When the door body 3 is opened from to the second central axis P moves relative to the guiding trajectory line S (the box body 1 or the hinge plate 4) towards the side close to the side wall of the first body and away from the plane where the pick-and-place opening is located. That is, the second shaft 6 moves relative to the guiding part 8 towards the side close to the side wall of the first body and away from the plane where the pick-and-place opening is located.

[0340] When the door body 3 is opened from During the process of opening to the first central axis Q moves relative to the guiding track line F (door body 3) towards the side close to the door side wall 33 and away from the front door wall 31. That is, the first axis 5 moves relative to the guiding part 8 towards the side close to the door side wall 33 and away from the front door wall 31.

[0341] When the opening angle of the door body 3 is the guiding track line F passes through the first central axis Q, and the first guiding point K of the guiding track line F is located at the second guiding position K2 relative to the box body 1; the second guiding point J of the guiding track line F is located at the second guiding point J2 relative to the box body 1.

[0342] When the opening angle of the door body 3 is the guiding track line F passes through the first central axis Q, and the first guiding point K of the guiding track line F is located at the third guiding position K3 relative to the box body 1; the second guiding point J of the guiding track line F is located at the third guiding point J3 relative to the box body 1. Among them, the third guiding position K3 is located on the side of the second guiding position K2 close to the first body side wall and away from the plane where the access opening is located. The third guiding point J3 is located on the side of the second guiding point J2 away from the first body side wall and the plane where the access opening is located.
