[0062] As described in the background art, in the related art, the door body is rotatably arranged on the box body through a hinge assembly, so that the accommodating cavity is closed or opened through the door body. In addition, the refrigerator is also provided with a wiring harness so that the box body and the door body can be connected to a power source through the wiring harness. However, in the process of opening or closing the door body through the hinge assembly, the door body rotates relative to the box body through the hinge assembly, so that friction is easily generated between the door body and the wiring harness connected to the door body, and the wiring harness is easily squeezed and damaged.

[0063] In view of this, in the refrigerator of the embodiment of the present application, when the door body is opened or closed by the hinge assembly, the hinge shaft and the hinge seat rotate relative to each other, so as to close or open the accommodating cavity through the door body. By providing an extension hole in the protective member, a connecting port in the hinge seat, and a wire path in the hinge shaft, the wire harness connected to the door body can extend from the door body through the extension hole, the connecting port, and the wire path to the hinge shaft in sequence, so that the wire harness can be protected to a certain extent by the hinge assembly, reducing the possibility of friction between the wire harness and the door body, and reducing the possibility of extrusion and damage to the wire harness;

[0064] Furthermore, by arranging a protective part on the hinge seat, the extension hole of the protective part is connected to the connecting port, the wiring harness can be passed through the extension hole and arranged in the connecting port, and the protective part can at least block part of the connecting port, so that the protective part can play a certain protective role on the hinge seat, and the protective part can intercept debris such as foaming materials in the door body, and reduce the possibility of debris entering the connecting port of the hinge seat, thereby reducing the possibility of contact and friction between the wiring harness and the debris, and reducing the possibility of the wiring harness getting stuck.

[0071] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0072] Reference Figure 1-Figure 3 An embodiment of the present application provides a refrigerator, which includes a cabinet 100 having a accommodating cavity 110, a door body 200 connected to the cabinet 100 to open and close the accommodating cavity 110, and a refrigeration device that supplies cold air to the accommodating cavity 110.

[0073] The cabinet 100 includes an inner container defining a receiving chamber 110 , an outer shell connected to the outer side of the inner container to form the appearance of a refrigerator, and an insulating layer provided between the inner container and the outer shell to insulate the receiving chamber 110 .

[0074] The box body 100 defines a plurality of accommodating chambers 110. In this embodiment, the plurality of accommodating chambers 110 may include a refrigerating chamber and a freezing chamber located below the refrigerating chamber. It should be noted that the types and arrangements of the plurality of accommodating chambers 110 of the refrigerator are not limited thereto.

[0075] The front end of the accommodating chamber 110 is formed with an access opening, through which a user can place food into the accommodating chamber 110 or take food out of the accommodating chamber 110. A rotatable door 200 is provided on the box body 100 to open or close the access opening of the accommodating chamber 110.

[0076] For example, the refrigerator may further include a hinge assembly 300, and the hinge assembly 300 may be disposed at least one of the upper portion of the door body 200 and the lower portion of the door body 200. For example, the hinge assembly 300 may be disposed at the upper portion of the door body 200 and the lower portion of the door body 200, so that the door body 200 may be rotatably connected to the cabinet 100 by the hinge assembly 300 located at the upper portion of the door body 200 and the hinge assembly 300 located at the lower portion of the door body 200.

[0077] The door body 200 may have a door rear wall close to the box body 100 when the door body 200 is closed, a door front wall away from the box body 100 when the door body 200 is closed, and a door side wall connected to the door rear wall. The door front wall and the door rear wall are arranged opposite to each other, the door front wall and the door side wall are connected to form a door front edge, and the door rear wall and the door side wall are connected to form a door rear edge. The door rear edge and the door front edge are arranged parallel to each other.

[0078] Reference Figure 1-Figure 3In some possible implementations, the hinge assembly 300 may be close to the door side wall so that the door body 200 can rotate relative to the box body 100 through the hinge assembly 300, thereby closing or opening the accommodating cavity 110 of the box body 100 through the door body 200.

[0079] Exemplarily, the hinge assembly 300 may include a hinge seat 310 and a hinge shaft 320. The hinge seat 310 may be disposed on the door body 200. The hinge seat 310 may be provided with a communication port 314. The hinge seat 310 may be provided with a protective member 330. The protective member 330 may have an extension hole 332, and the extension hole 332 is connected to the communication port 314 and the door body 200, so that the door body 200 can be connected to the communication hole through the extension hole 332.

[0080] The hinge shaft 320 may be disposed on the housing 100 , and the hinge shaft 320 is rotatably connected to the hinge seat 310 , so that the door body 200 can rotate relative to the housing 100 . The hinge shaft 320 may be provided with a wire passage, and the wire passage may be connected to the communication port 314 .

[0081] The refrigerator may further include a wire harness 400, which is connected to the door body 200, so that the door body 200 and the cabinet 100 can be connected to a power source and other structures through the wire harness 400. The wire harness 400 can extend from the door body 200 through the extension hole 332, the communication port 314 and the wire passage to the hinge shaft 320, so that the hinge assembly 300 can protect the wire harness 400 to a certain extent, reduce the possibility of friction between the wire harness 400 and the door body 200, and reduce the possibility of extrusion and damage of the wire harness 400.

[0082] It is easy to understand that part of the wire harness 400 can be arranged on the door body 200. The door body 200 can be connected to a power source and other structures through the wire harness 400. The box body 100 can be connected to a power source and other structures through the wire harness 400, and the embodiment of the present application does not make further restrictions on this.

[0083] Exemplarily, the number of the hinge shaft 320 can be set to one, and during the process of rotating the door body 200 to open or rotate to close, the door body 200 can rotate relative to the box body 100 around the hinge shaft 320.

[0084] Alternatively, the refrigerator may be configured as a built-in refrigerator. The number of hinge shafts 320 may be set to two, and at least one hinge shaft 320 may be used to form a wire channel 321 .

[0085] Reference Figure 1 , Figure 3 and Figure 4In some possible implementations, the hinge seat 310 may include a mounting portion 311 and an extension portion 312 connected to each other. The mounting portion 311 may be connected to the door body 200. The extension portion 312 is formed with a sliding groove 313 for accommodating the hinge shaft 320, and the bottom of the sliding groove 313 faces the extension hole 332, so that the wire harness 400 in the hinge shaft wire channel 321 can extend into the accommodating groove 331 through the sliding groove 313.

[0086] Exemplarily, the mounting portion 311 can be connected to the door body 200 by plugging or snapping. For example, the door body 200 can be provided with an end cover 210, and the end cover 210 can be located at the top of the door body 200. The mounting portion 311 can be connected to the end cover 210 by snapping, so that the connection between the mounting portion 311 and the end cover 210 is more convenient.

[0087] The mounting portion 311 may be a square mounting portion 311. The end cover 210 may be provided with a square mounting opening, which accommodates the square mounting portion 311 so that the square mounting portion 311 can be relatively fixed to the end cover 210, thereby achieving the installation of the mounting portion 311 and the door body 200.

[0088] The extension portion 312 may be disposed on a side of the mounting portion 311 away from the hinge shaft 320. One end of the extension portion 312 away from the mounting portion 311 may extend downward in a vertical direction. The extension portion 312 may be disposed between the end cover 210 and the door body 200, so that the end cover 210 can provide a certain degree of protection for the extension portion 312, thereby reducing the possibility of the extension portion 312 being damaged by collision.

[0089] The shape of the extension portion 312 can be adjusted according to the shape of the sliding groove 313. For example, the number of hinge shafts 320 can be set to one, the sliding groove 313 can be set to a circular sliding groove 313, and the shape of the extension portion 312 can be set to a circular tube, with the plane perpendicular to the extension direction of the extension portion 312 as the cross-section, and the cross-sectional shape of the extension portion 312 is set to be circular.

[0090] Alternatively, the number of hinge shafts 320 is set to two, and the sliding groove 313 can be set to a linear sliding groove 313, or the sliding groove 313 can be set to a curved sliding groove 313. The shape of the extension 312 can be determined according to the shape of the sliding groove 313, and the extension 312 forms the side wall of the sliding groove 313, and the side wall of the sliding groove 313 can be relatively uniformly arranged.

[0091] It is easy to understand that the communication port 314 is arranged at the bottom of the sliding groove 313. Taking the plane perpendicular to the extension direction of the extension portion 312 as the cross section, the cross-sectional area of ​​the communication port 314 can be equal to the area of ​​the sliding groove 313, that is, the extension portion 312 can be tubular, and the shape of the extension portion 312 connected to one end of the mounting portion 311 is arranged in the same shape as the end of the extension portion 312 away from the mounting portion 311, thereby increasing the area of ​​the communication port 314, increasing the range of movement of the wire harness 400 in the communication port 314, and reducing the possibility of the wire harness 400 being squeezed and damaged by the extension portion 312.

[0092] Exemplarily, in the extension direction of the hinge axis 320, the length of the hinge axis 320 may be greater than or equal to 20% of the depth of the sliding groove 313 and less than or equal to 70% of the depth of the sliding groove 313. For example, the ratio of the length of the hinge axis 320 to the depth of the sliding groove 313 may be set within any ratio range of 20%-30%, 30%-40%, 40%-50%, 50%-60%, and 60%-70%.

[0093] In this way, in the extension direction of the hinge shaft 320, the length of the hinge shaft 320 is greater than or equal to 20% of the depth of the sliding groove 313, so as to ensure the stability of the hinge shaft 320 in the sliding groove 313 and reduce the possibility of the hinge shaft 320 escaping from the sliding groove 313;

[0094] In the extension direction of the hinge axis 320, the length of the hinge axis 320 is less than or equal to 70% of the depth of the sliding groove 313, so that the length of the wire path is less than or equal to 70% of the depth of the sliding groove 313, thereby increasing the range of movement of the wire harness 400 between the bottom surface of the sliding groove 313 and the wire path, reducing the possibility of damage or breakage of the wire harness 400 when it is tightened, and making the structure of the wire harness 400 more stable.

[0095] Reference Figure 1 , Figure 3-Figure 5 In some possible implementations, the protective member 330 may be an elastic protective member 330. The elastic protective member 330 may be made of a soft material such as rubber. The elastic protective member 330 may be sleeved on the outer side of the hinge seat 310 to improve the connection effect between the elastic protective member 330 and the hinge seat 310 through the elastic force of the elastic protective member 330, thereby reducing the possibility of the elastic protective member 330 and the hinge seat 310 being separated.

[0096] Exemplarily, the shape of the elastic protective member 330 may be adapted to the shape of the outer surface of the extension portion 312. For example, when the shape of the outer surface of the extension portion 312 is set to be cylindrical, the inner surface of the elastic protective member 330 may be set to be cylindrical, and the diameter of the elastic protective member 330 may be smaller than the diameter of the outer surface of the extension portion 312, so that the elastic protective member 330 can be stretched to produce deformation, thereby increasing the connection force between the elastic protective member 330 and the hinge seat 310.

[0097] Alternatively, when the number of hinge shafts 320 is set to two, the shape of the extension portion 312 can be set to other shapes, the shape of the elastic protective member 330 can be set to the same shape as the extension portion 312, and the size of the elastic protective member 330 can be smaller than the size of the extension portion 312.

[0098] Exemplarily, the protective member 330 may also be installed on the door body 200. The protective member 330 may be configured as a rigid protective member 330, and the rigid protective member 330 may be relatively fixed to the hinge seat 310, so that the rigid protective member 330 plays a certain protective role on the hinge seat 310.

[0099] For example, the protective member 330 can be relatively fixed to the door body 200 by means of snap connection or screw connection, and the hinge seat 310 can be installed on the protective member 330, so that the hinge seat 310 can be relatively fixed to the door body 200 through the protective member 330. Thus, the function of the protective member 330 is more abundant.

[0100] The protective member 330 may have a receiving groove 331, and the receiving cavity 110 may receive at least a portion of the extension portion 312. The first end of the extension hole 332 may be connected to the receiving groove 331, and the second end of the extension hole 332 may face the door body 200, so that the wire harness 400 can be connected to the door body 200 from the receiving groove 331 through the extension hole 332, thereby achieving the connection between the wire harness 400 and the door body 200.

[0101] Reference Figure 1 , Figure 6-Figure 8 In some possible embodiments, the bottom surface of the accommodating groove 331 and the connecting port 314 can be spaced apart in the vertical direction, and at least a portion of the extension hole 332 faces the connecting port 314, so that the wiring harness 400 can pass through the accommodating groove 331 and penetrate into the extension hole 332 and the connecting port 314.

[0102] The bottom surface of the accommodating groove 331 is spaced apart from the connecting port 314, and at least a portion of the extension hole 332 faces the connecting port 314, thereby reducing the possibility of the wiring harness 400 being bent between the bottom surface of the accommodating groove 331 and the connecting port 314, and reducing the possibility of the wiring harness 400 being squeezed and damaged when contacting the hinge seat 310 and the protective member 330.

[0103] Alternatively, in the extension direction of the hinge shaft 320, the bottom surface of the receiving groove 331 abuts against at least part of the extension portion 312. This makes the installation process of the protective member 330 more convenient, the connection between the protective member 330 and the hinge seat 310 more stable, and reduces the possibility of the protective member 330 and the hinge seat 310 being separated.

[0104] And / or, in the extension direction of the hinge shaft 320, the depth of the receiving groove 331 may be greater than or equal to 30% of the length of the extension portion 312 and less than or equal to 80% of the length of the extension portion 312. For example, the ratio of the depth of the receiving groove 331 to the length of the extension portion 312 may be set within any ratio range of 20%-30%, 30%-40%, 40%-50%, 50%-60%, 60%-70%, and 70%-80%.

[0105] By setting the depth of the accommodating groove 331 to be greater than or equal to 30% of the length of the extension portion 312 and less than or equal to 80% of the length of the extension portion 312, the length of the wiring harness 400 between the extension portion 312 and the bottom of the accommodating groove 331 is increased, and the possibility of damage or breakage of the wiring harness 400 when it is tightened is reduced, making the structure of the wiring harness 400 more stable.

[0106] In some possible implementations, the extension hole 332 may be disposed on the inner wall of the protection member 330 . The extension hole 332 may have a first portion and a second portion connected to each other, and the first portion and the second portion may be arranged in a direction away from the receiving groove 331 .

[0107] Taking a plane perpendicular to the extending direction of the extending hole 332 as a cross section, the cross-sectional area of ​​the first portion gradually decreases in a direction away from the receiving groove 331. The inner wall of the second portion may be attached to the surface of the wire harness 400.

[0108] Taking the plane perpendicular to the extending direction of the extension hole 332 as the cross section, the cross-sectional area of ​​the first portion gradually decreases in the direction away from the accommodating groove 331, so that the first portion of the extension hole 332 can play a certain guiding role on the wire harness 400, making the process of the wire harness 400 passing through the extension hole 332 more convenient;

[0109] The inner wall of the second portion of the extension hole 332 fits against the surface of the wire harness 400, thereby reducing the gap between the inner wall of the extension hole 332 and the wire harness 400, reducing the possibility of debris entering the extension hole 332, and reducing the possibility of contact and friction between the wire harness 400 and debris.

[0110] Alternatively, the protective member 330 may be provided with an extension tube 333. The extension tube 333 may be provided on a side of the protective member 330 away from the hinge seat 310, and an extension hole 332 may be formed on the inner surface of the extension tube 333. An end of the extension tube 333 away from the protective member 330 is provided with a fitting portion 3331, and the inner wall of the fitting portion 3331 is at least used to fit the surface of the wiring harness 400.

[0111] It is easy to understand that the extension tube 333 is arranged on the side of the protective member 330 away from the hinge seat 310, and the inner surface of the extension tube 333 forms an extension hole 332, so that the wire harness 400 can be arranged inside the extension tube 333, so that the extension tube 333 can play a certain supporting and protective role on the wire harness 400;

[0112] The end of the extension tube 333 facing away from the protective member 330 is provided with a fitting portion 3331, and the inner wall of the fitting portion 3331 is at least used to fit the surface of the wiring harness 400, so as to reduce the gap between the extension tube 333 and the wiring harness 400 through the fitting portion 3331, reduce the possibility of debris entering the extension tube 333 through the fitting portion 3331, and reduce the possibility of contact and friction between the wiring harness 400 and debris.

[0113] The protection member 330 is provided with an extension tube 333 , and an extension hole 332 is formed on the inner surface of the extension tube 333 . The extension hole 332 has a first portion and a second portion connected in the extension tube 333 , and the first portion and the second portion may be arranged in a direction away from the receiving groove 331 .

[0114] Taking the plane perpendicular to the extending direction of the extending hole 332 as the cross section, the cross-sectional area of ​​the first portion gradually decreases in the direction away from the receiving groove 331 ; the inner wall of the second portion can be attached to the surface of the wire harness 400 .

[0115] Reference Figure 1 -, Fig. 9 and Fig.10 In some possible implementations, the hinge assembly 300 may further include a hinge plate 340 and a protective cover 350. The hinge shaft 320 may be connected to the box 100 through the hinge plate 340. The protective cover 350 is connected to the hinge plate 340, and the protective cover 350 and the hinge plate 340 form a protective channel, which accommodates at least part of the wire harness 400.

[0116] The protective cover 350 is connected to the hinge plate 340. The protective cover 350 and the hinge plate 340 form a protective channel. The protective channel accommodates at least part of the wiring harness 400, so that the protective channel can provide a certain degree of protection for the wiring harness 400, further reducing the possibility of friction between the wiring harness 400 and the door body 200, and reducing the possibility of extrusion and damage of the wiring harness 400.

[0117] In summary, in the process of opening or closing the door body 200 through the hinge assembly 300, the hinge shaft 320 and the hinge seat 310 rotate relative to each other, so as to close or open the accommodating cavity 110 through the door body 200. By providing an extension hole 332 in the protective member 330, a connecting port 314 in the hinge seat 310, and a wire passage in the hinge shaft 320, the wire harness 400 connected to the door body 200 can extend out of the hinge shaft 320 from the door body 200 through the extension hole 332, the connecting port 314, and the wire passage in sequence, so that the hinge assembly 300 can provide a certain degree of protection for the wire harness 400, reduce the possibility of friction between the wire harness 400 and the door body 200, and reduce the possibility of extrusion and breakage of the wire harness 400;

[0118] Furthermore, by providing a protective member 330 on the hinge seat 310, the extension hole 332 of the protective member 330 is connected to the connecting port 314, and the wiring harness 400 can be passed through the extension hole 332 and arranged in the connecting port 314. The protective member 330 can at least block a portion of the connecting port 314, so that the protective member 330 can play a certain protective role on the hinge seat 310. The protective member 330 can intercept debris such as foaming materials in the door body 200, and reduce the possibility of debris entering the connecting port 314 of the hinge seat 310, thereby reducing the possibility of contact and friction between the wiring harness 400 and the debris, and reducing the possibility of the wiring harness 400 getting stuck.

[0119] The embodiment of the present application provides a refrigerator, comprising a box body 100, a door body 200 and a hinge assembly 300, wherein the door body 200 is rotatably disposed on the box body 100 through the hinge assembly 300 to close or open a receiving cavity 110;
