[0012] In the process of rotating to open the door body, the rear wall of the door body gradually moves away from the box body, the hinge shaft moves from the first end of the sliding groove to the second end of the sliding groove, the guide part slides from the first end of the guide groove to the second end of the guide groove, the hinge shaft can drive the door body to move toward the inner side of the box body, and the door rear edge formed by the door rear wall and the door side wall can move toward the inner side of the box body, thereby realizing the embedded design of the refrigerator and reducing the possibility of collision between the refrigerator door body and the inner wall of the cabinet;

[0013] On the hinge seat, the sliding groove and the guide groove are arranged in the vertical direction; on the hinge shaft, the guide part and the hinge shaft are arranged in the vertical direction. Compared with the horizontal arrangement in the related art, the refrigerator of the embodiment of the present application can make the arrangement of the sliding groove and the guide groove more compact, simplify the structure of the hinge assembly, and reduce the assembly space required for the hinge assembly.

[0014] In some embodiments of the present application, the sliding groove is provided with an inflection point;

[0015] The inflection point divides the sliding groove into a curved groove section and a straight groove section; the portion of the sliding groove located between the first end of the sliding groove and the inflection point forms the straight groove section, and the portion of the sliding groove located between the inflection point and the second end of the sliding groove forms the curved groove section.

[0016] With such arrangement, in the process of rotating and opening the door body, the rear wall of the door body gradually moves away from the box body, and the hinge shaft slides from the straight groove section of the sliding groove to the curved groove section.

[0025] When the hinge shaft slides in the curved groove section, the door body can move in the curved groove driven by the hinge shaft, and the guide part is located in the second part of the guide groove, so the door body has a larger rotation angle. The door body rotates driven by the guide part, so that the rotation angle of the door body when the hinge shaft is in the straight groove section is smaller than the rotation angle of the door body when the hinge shaft is in the curved groove section, thereby reducing the possibility of the door body colliding with the inner wall of the cabinet.

[0026] In some embodiments of the present application, the first end of the guide groove is away from the door side wall relative to the first end of the sliding groove, and the first end of the guide groove is away from the door rear wall relative to the first end of the sliding groove;

[0027] The second end of the guide groove is far away from the door side wall relative to the second end of the sliding groove, the second end of the guide groove is close to the door side wall relative to the first end of the sliding groove, and the second end of the guide groove is close to the door rear wall relative to the second end of the sliding groove.

[0028] With such arrangement, during the process of rotating the door body to open, the rear wall of the door body gradually moves away from the box body, the hinge shaft moves from the first end of the sliding groove to the second end of the sliding groove, the guide portion slides from the first end of the guide groove to the second end of the guide groove, and the hinge shaft can drive the door body to move toward the inner side of the box body, and the rear edge of the door formed by the rear wall of the door and the side walls of the door can move toward the inner side of the box body, thereby realizing the embedded design of the refrigerator and reducing the possibility of collision between the door body of the refrigerator and the inner wall of the cabinet.

[0029] In some embodiments of the present application, when the door body is closed, the door side wall of the door body is located in a set plane;

[0030] The door body also has a door front wall arranged opposite to the door rear wall, and the door side walls of the door body and the door front wall of the door body form a door front edge; during the process of rotating to open the door body, the door front edge is located on the side of the set plane facing the box body.

The door front wall 210 and the door rear wall 220 are arranged opposite to each other, the door front wall 210 and the door side wall 230 are connected to form a door front edge 240, and the door rear wall 220 and the door side wall 230 are connected to form a door rear edge 250. The door rear edge 250 and the door front edge 240 are arranged parallel to each other.

[0082] In some possible implementations, the hinge assembly 300 may be close to the door sidewall 230 , so that the door body 200 can rotate relative to the box body 100 through the hinge assembly 300 , so as to close or open the accommodating cavity through the door body 200 .

[0083] Reference Figure 3-Figure 6The hinge assembly 300 may include a hinge shaft 320 and a hinge seat 310. One of the hinge shaft 320 and the hinge seat 310 is disposed on the housing 100, and the other of the hinge shaft 320 and the hinge seat 310 is disposed on the door body 200. For example, the hinge seat 310 may be disposed on the door body 200, and the hinge seat 310 may face the housing 100 in a vertical direction. The hinge shaft 320 may be disposed on the housing 100, and the hinge shaft 320 may face the door body 200 in a vertical direction.

[0084] Alternatively, the hinge base 310 may be disposed on the box body 100, and the hinge base 310 may face the door body 200 in a vertical direction. The hinge shaft 320 may be disposed on the door body 200, and the hinge shaft 320 may face the box body 100 in a vertical direction.

[0085] Exemplarily, the hinge assembly 300 may be disposed on the upper end of the door body 200. The hinge seat 310 may be disposed on the door body 200, and the hinge seat 310 may be vertically upward toward the box body 100. The hinge shaft 320 may be disposed on the box body 100, and the hinge shaft 320 may be vertically downward toward the door body 200.

[0086] The hinge assembly 300 may be disposed at the lower end of the door body 200. The hinge seat 310 may be disposed at the door body 200, and the hinge seat 310 may be vertically downward toward the box body 100. The hinge shaft 320 may be disposed at the box body 100, and the hinge shaft 320 may be vertically upward toward the door body 200.

[0087] For example, refer to Figure 5 and Figure 6 The hinge seat 310 may be provided with a connected sliding groove 311 and a guide groove 312. The sliding groove 311 and the guide groove 312 are arranged in the vertical direction, so that compared with the horizontal arrangement, the sliding groove 311 and the guide groove 312 arranged in the vertical direction can reduce the assembly space required for the hinge seat 310 and simplify the structure of the hinge seat 310.

[0088] On the hinge base 310 , a first end of the sliding groove 311 may be close to the door sidewall 230 , and a second end of the sliding groove 311 may be away from the door sidewall 230 .

[0089] The guide groove 312 can be close to the door rear wall 220 relative to the sliding groove 311. The first end of the guide groove 312 can be close to the door side wall 230, and the second end of the guide groove 312 can be far away from the door side wall 230. The first end of the guide groove 312 can be close to the door rear wall 220, and the second end of the guide groove 312 can be far away from the door rear wall 220.

[0090] The hinge shaft 320 can be slidably disposed in the sliding groove 311, so that the movement process of the position of the door body 200 can be realized through the cooperation of the hinge shaft 320 and the sliding groove 311. The hinge shaft 320 is provided with a guide portion 321. The guide portion 321 and the hinge shaft 320 are arranged in the vertical direction, and the guide portion 321 can be slidably disposed in the guide groove 312, so that the angle of the door body 200 can be adjusted through the cooperation of the guide portion 321 and the guide groove 312.

[0091] In the process of rotating and opening the door body 200, the rear wall of the door body 200 gradually moves away from the box body 100, the hinge shaft 320 moves from the first end of the sliding groove 311 to the second end of the sliding groove 311, and the guide portion 321 slides from the first end of the guide groove 312 to the second end of the guide groove 312, and the hinge shaft 320 can drive the door body 200 to move toward the inner side of the box body 100, and the door rear edge 250 formed by the door rear wall 220 and the door side wall 230 can move toward the inner side of the box body 100, thereby realizing the embedded design of the refrigerator and reducing the possibility of collision between the door body 200 of the refrigerator and the inner wall of the cabinet 400;

[0092] On the hinge seat 310, the sliding groove 311 and the guide groove 312 are arranged in the vertical direction; on the hinge shaft 320, the guide part 321 and the hinge shaft 320 are arranged in the vertical direction. Compared with the horizontal arrangement in the related art, the refrigerator of the embodiment of the present application can make the arrangement of the sliding groove 311 and the guide groove 312 more compact, simplify the structure of the hinge assembly 300, and reduce the assembly space required for the hinge assembly 300.

[0093] In some possible implementations, along the vertical direction, the sliding groove 311 may be away from the box body 100 relative to the guide groove 312 .

[0094] This arrangement can make the length of the hinge shaft 320 along the vertical direction greater than the length of the guide portion 321 along the vertical direction, making the structure of the hinge shaft 320 more stable and the connection between the hinge shaft 320 and the sliding groove 311 more stable, reducing the possibility of separation between the hinge shaft 320 and the sliding groove 311.

[0095] For example, the hinge shaft and the guide part 321 can be integrally arranged, so that the structure of the hinge shaft and the guide part 321 is more stable. Alternatively, the hinge shaft and the guide part 321 can also be connected by welding or clamping, so that the guide part 321 can be relatively fixed to the hinge shaft.

[0096] Alternatively, the hinge shaft and the guide portion 321 may also be formed in other ways, for example, referring to Figure 3 and Figure 4The hinge shaft 320 may include a rotating member 320a and a rotating sleeve 320b, and the rotating sleeve 320b may be sleeved on the outer side of the rotating member 320a. The matching rotating member 320a and the rotating sleeve 320b are used to form a guide portion 321 connected to the hinge shaft 320, so that the force of the hinge shaft is more uniform and the structure of the hinge shaft is more stable.

[0097] The rotating sleeve 320b may include a first portion and a second portion connected to each other, and the first portion of the rotating sleeve 320b is away from the housing 100 relative to the second portion of the rotating sleeve 320b. The first portion of the rotating sleeve 320b and the second portion of the rotating sleeve 320b may be integrally arranged to make the structure of the rotating sleeve 320b more stable. The first portion of the rotating sleeve 320b may be arranged in the sliding groove 311, and the second portion of the rotating sleeve 320b may form a guide portion 321.

[0098] Illustratively, the hinge shaft 320 may be provided with a connecting portion 322 , one end of the connecting portion 322 facing away from the hinge shaft 320 is connected to the guide portion 321 , and the hinge shaft 320 may be connected to the guide portion 321 via the connecting portion 322 .

[0099] In the direction of the line between the hinge shaft 320 and the guide portion 321, the width of the connection portion 322 can gradually decrease in the direction close to the guide portion 321. The width of the end of the connection portion 322 connected to the hinge shaft 320 is greater than the width of the end of the connection portion 322 connected to the guide portion 321.

[0100] For example, in the plane where the hinge shaft 320 and the guide portion 321 are located, the shapes of the connecting portion 322 and the guide portion 321 can form a triangle together. The end of the guide portion 321 away from the hinge shaft 320 can be set as an arc-shaped portion to reduce the friction between the guide portion 321 and the inner wall of the guide groove 312, so that the movement process of the guide portion 321 in the guide groove 312 is more stable.

[0101] Exemplarily, the guide groove 312 may have a first limiting portion, and when the guide portion 321 is located at the first end of the guide groove 312 , the first limiting portion may fit the connecting portion 322 .

[0102] And / or, the guide groove 312 may have a second limiting portion, and when the guide portion 321 is located at the second end of the guide groove 312 , the second limiting portion may fit the connecting portion 322 .

[0103] In this configuration, when the guide portion 321 is located at the first end of the guide groove 312, the first limiting portion is in contact with the connecting portion 322, so that the first limiting portion plays a certain limiting role in the rotation process of the hinge shaft 320;

[0104] When the guide portion 321 is located at the second end of the guide groove 312, the second limiting portion fits the connecting portion 322, so that the second limiting portion plays a certain limiting role in the rotation process of the hinge shaft 320, so that the first limiting portion and the second limiting portion can cooperate with each other, so that the rotation process of the guide portion 321 in the guide groove 312 can be more stable.

[0105] In the vertical direction, the length of the guide portion 321 may be greater than or equal to 15% of the length of the hinge shaft 320 and less than or equal to 60% of the length of the hinge shaft 320. For example, the length of the guide portion 321 may be set within any ratio range of 15%-30%, 30%-45%, and 45%-60% of the length of the hinge shaft 320 to reduce the possibility of the guide portion 321 being separated from the guide groove 312.

[0106] Reference Figure 7-Figure 11 In some possible implementations, the sliding groove 311 may be provided with an inflection point. The inflection point divides the sliding groove 311 into a curved groove section and a straight groove section. The portion of the sliding groove 311 between the first end of the sliding groove 311 and the inflection point forms a straight groove section, and the portion of the sliding groove 311 between the inflection point and the second end of the sliding groove 311 forms a curved groove section.

[0107] In the direction close to the door side wall 230, the extension direction of the straight groove section can gradually approach the door rear wall 220. In the direction close to the door side wall 230, the extension direction of the curved groove section can gradually move away from the door rear wall 220.

[0108] The inflection point of the sliding groove 311 can be determined in the following manner. When the extension direction of the straight groove section gradually approaches the door rear wall 220, a straight line parallel to the door rear wall 220 and perpendicular to the door side wall 230 can be used as a tangent line, and the tangent line can be gradually moved from the door rear wall 220 toward the door front wall 210, so that the sliding groove 311 can be tangent to the tangent line, and the point where the sliding groove 311 is tangent to the tangent line is the inflection point of the sliding groove 311.

[0109] When the extension direction of the straight groove segment gradually moves away from the door rear wall 220, a straight line parallel to the door rear wall 220 and perpendicular to the door side wall 230 can be used as a tangent, and the tangent can be gradually moved from the door front wall 210 toward the door rear wall 220, so that the sliding groove 311 can be tangent to the tangent, and the point where the sliding groove 311 is tangent to the tangent is the inflection point of the sliding groove 311.

[0110] It should be noted that the straight groove segment can be used to indicate that when the hinge shaft 320 moves in the straight groove segment of the sliding groove 311, without considering the rotation of the hinge shaft 320, the moving direction of the hinge shaft 320 is parallel to the extension direction of the straight groove segment, or the moving direction of the hinge shaft 320 is approximately parallel to the extension direction of the straight groove segment.

[0111] Alternatively, the type of the sliding groove 311 can be determined by the shape of the side wall of the straight groove segment. For example, if the side wall of a portion of the sliding groove 311 extends in a straight direction, the portion of the sliding groove 311 can be determined as a straight groove segment.

[0112] The curved groove segment can be used to indicate that when the hinge shaft 320 moves in the curved groove segment of the sliding groove 311, the hinge shaft 320 moves along a curved path without considering the self-rotation of the hinge shaft 320. The type of the sliding groove 311 can be determined according to the inner wall of the curved groove segment. For example, if the side wall of a part of the sliding groove 311 extends along an arc direction, the part of the sliding groove 311 can be determined as a curved groove segment.

[0113] In the process of rotating and opening the door body 200, the rear wall of the door body 200 gradually moves away from the box body 100, and the hinge shaft 320 slides from the straight groove section of the sliding groove 311 to the curved groove section. Figure 7-Figure 9 When the hinge shaft 320 slides in the straight groove section, the door body 200 can slide toward the inner side of the box body 100 along the extension direction of the straight groove section driven by the hinge shaft 320, and the door body 200 rotates under the drive of the guide part 321;

[0114] Reference Figure 9-11 When the hinge shaft 320 slides in the curved groove section, the door body 200 can move in the curved groove driven by the hinge shaft 320, and the door body 200 rotates driven by the guide part 321, so that the rotation angle of the door body 200 when the hinge shaft 320 is in the straight groove section is smaller than the rotation angle of the door body 200 when the hinge shaft 320 is in the curved groove section, thereby reducing the possibility of collision between the door body 200 and the inner wall of the cabinet 400.

[0115] Exemplarily, the sliding groove 311 may be provided with an inflection point. The inflection point divides the sliding groove 311 into a first part and a second part connected to each other, the first part may be provided as a straight groove section or a curved groove section, and the second part may be provided as a straight groove section or a curved groove section.

[0116] Alternatively, the first portion may be configured as a first straight slot segment, and the second portion may be configured as a second straight slot segment. The inflection point connects the two straight slot segments, and the extension direction of the first straight slot segment may gradually approach the door rear wall 220, and the extension direction of the second straight slot segment may gradually move away from the door rear wall 220.

[0117] Alternatively, the first portion may be configured as a curved slot segment, and the second portion may be configured as a straight slot segment. The inflection point connects the curved slot segment and the straight slot segment, and the extending direction of the curved slot segment may gradually approach the door rear wall 220, and the extending direction of the straight slot segment may gradually move away from the door rear wall 220.

[0118] Alternatively, the first portion can be configured as a first curved groove segment, and the second portion can be configured as a second curved groove segment. The inflection point connects the two curved groove segments, and the extension direction of the first curved groove segment can gradually approach the door rear wall 220, and the extension direction of the second curved groove segment can gradually move away from the door rear wall 220.

[0119] Exemplarily, the guide groove 312 may include a first portion and a second portion connected to each other. When the hinge shaft 320 is located in the straight groove section, the guide portion 321 is located in the first portion of the guide groove 312. When the hinge shaft 320 is located in the curved groove section, the guide portion 321 is located in the second portion of the guide groove 312.

[0120] Reference Figure 5 and Figure 6 The straight groove section and the first portion of the guide groove 312 may be inclined relative to the door sidewall 230. The inclination angle of the straight groove section relative to the door sidewall 230 may be greater than the inclination angle of the first portion of the guide groove 312 relative to the door sidewall 230.

[0121] It should be noted that the first portion of the guide groove 312 can be set as a straight line portion. The first portion of the guide groove 312 can extend along a straight line, or the first portion of the guide groove 312 can extend approximately along a straight line.

[0122] The inclination angle of the first portion of the guide groove 312 can be determined according to the angle between the extension direction of the first portion of the guide groove 312 and the door side wall 230. For example, taking a straight line parallel to the door side wall 230 and perpendicular to the door rear wall 220 as a reference line, the angle between the extension direction of the inner wall of the first portion of the guide portion 321 and the reference line can be set as the inclination angle of the first portion of the guide groove 312 relative to the door side wall 230.

[0123] Taking a straight line parallel to the door side wall 230 and perpendicular to the door rear wall 220 as a reference line, the angle between the inner wall extension direction of the straight groove segment and the reference line can be set as the inclination angle of the straight groove segment relative to the door side wall 230 .

[0124] Alternatively, the first portion of the guide groove 312 may be configured as a curved portion.

[0125] Reference Figure 5 The inclination angle of the first portion of the guide groove 312 can be determined according to the angle between the extension direction of the first portion of the guide groove 312 and the door side wall 230. For example, with a straight line parallel to the door side wall 230 and perpendicular to the door rear wall 220 as a reference line, the angle between the tangent direction of the inner wall of the first portion of the guide portion 321 and the reference line can be set as the inclination angle of the first portion of the guide groove 312 relative to the door side wall 230.

[0126] The first end of the guide groove 312 is away from the door side wall 230 relative to the first end of the sliding groove 311, and the first end of the guide groove 312 is away from the door rear wall 220 relative to the first end of the sliding groove 311. The second end of the guide groove 312 is away from the door side wall 230 relative to the second end of the sliding groove 311, the second end of the guide groove 312 is close to the door side wall 230 relative to the first end of the sliding groove 311, and the second end of the guide groove 312 is close to the door rear wall 220 relative to the second end of the sliding groove 311.

[0127] During the process of rotating and opening the door body 200, the rear wall of the door body 200 gradually moves away from the box body 100, the hinge shaft 320 moves from the first end of the sliding groove 311 to the second end of the sliding groove 311, and the guide part 321 slides from the first end of the guide groove 312 to the second end of the guide groove 312.

[0128] The hinge shaft 320 can drive the door body 200 to move toward the inside of the box body 100, and the door rear edge 250 formed by the door rear wall 220 and the door side wall 230 can move toward the inside of the box body 100, thereby realizing the embedded design of the refrigerator and reducing the possibility of collision between the refrigerator door body 200 and the inner wall of the cabinet 400.

[0129] Exemplarily, when the door body 200 is closed, the door side wall 230 of the door body 200 is located in the set plane. The door side wall 230 of the door body 200 and the door front wall 210 of the door body 200 form a door front edge 240. In the process of rotating the door body 200 to open, the door front edge 240 is located on the side of the set plane facing the box body 100.

[0130] With such arrangement, during the process of rotating and opening the door body 200, the rear wall of the door body 200 gradually moves away from the box body 100, and the door front edge 240 is located on the side of the set plane facing the box body 100, thereby reducing the possibility of the door front edge 240 colliding with the inner wall of the cabinet 400.

[0131] In summary, in the process of rotating and opening the door body 200, the rear wall of the door body 200 gradually moves away from the box body 100, the hinge shaft 320 moves from the first end of the sliding groove 311 to the second end of the sliding groove 311, and the guide portion 321 slides from the first end of the guide groove 312 to the second end of the guide groove 312, and the hinge shaft 320 can drive the door body 200 to move toward the inner side of the box body 100, and the door rear edge 250 formed by the door rear wall 220 and the door side wall 230 can move toward the inner side of the box body 100, thereby realizing the embedded design of the refrigerator and reducing the possibility of collision between the door body 200 of the refrigerator and the inner wall of the cabinet 400;

[0132] On the hinge seat 310, the sliding groove 311 and the guide groove 312 are arranged in the vertical direction; on the hinge shaft 320, the guide part 321 and the hinge shaft 320 are arranged in the vertical direction. Compared with the horizontal arrangement in the related art, the refrigerator of the embodiment of the present application can make the arrangement of the sliding groove 311 and the guide groove 312 more compact, simplify the structure of the hinge assembly 300, and reduce the assembly space required for the hinge assembly 300.
