[0102] The technical solutions in the embodiments of the application will be described clearly and completely in the following with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are only a part of the embodiments of the application, not all the embodiments. Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the application.

[0103] In combination with Figure 1 and Figure 2 , some embodiments of the application provide a refrigerator, which can include a cabinet 10, which can be configured to form a storage compartment 11 with one side open for storing articles. As shown in Figure 2 , the opening of the storage compartment 11 is upward.

[0104] The cabinet 10 can include a cabinet body and a cabinet shell 100. The cabinet body can be configured to form a storage compartment 11 with a top side opening. The cabinet shell 100 can be connected to the outside of the cabinet body to form the appearance of the refrigerator.

[0105] As shown in Figure 3As shown, the cabinet shell 100 can include a front side plate 110, a rear side plate 120, a first side plate 130, a second side plate 140, and a bottom plate. The front side plate 110 and the rear side plate 120 are arranged in a front-rear direction (corresponding to a Y-axis direction) of the refrigerator and are spaced apart from each other. The first side plate 130 and the second side plate 140 are arranged in a left-right direction (corresponding to an X-axis direction) of the refrigerator and are connected to the front side plate 110 and the rear side plate 120, respectively. The front side plate 110, the rear side plate 120, the first side plate 130, and the second side plate 140 form a rectangular frame and are fixed to the bottom plate to form a cavity with a top opening, so that the cabinet is installed in the cavity. Figure 3 Figure 3 The front side plate 110, the rear side plate 120, the first side plate 130, and the second side plate 140 form a rectangular frame and are fixed to the bottom plate to form a cavity with a top opening, so that the cabinet is installed in the cavity.

[0106] Of course, at least two of the front side plate 110, the rear side plate 120, the first side plate 130, the second side plate 140, and the bottom plate can be an integral piece to improve the sealing performance of the cabinet shell 100 and simplify assembly. For example, the front side plate 110, the first side plate 130, and the second side plate 140 are an integral piece.

[0107] In the embodiments of the present application, the side where the cabinet 10 is rotationally connected to the door body 20 is the rear side, and the side of the refrigerator facing the user is the front side.

[0108] Continuing to refer to Figure 3 In some embodiments of the present application, the cabinet 10 can further include a cabinet frame 200 configured to form an opening of the storage compartment 11. The cabinet frame 200 is connected to the top end of the cabinet shell 100.

[0109] The cabinet 10 can further include a cabinet heat insulation layer, which can be arranged between the cabinet and the cabinet shell 100. The cabinet heat insulation layer can insulate the storage compartment 11 to minimize heat exchange between the storage compartment 11 and the outside of the refrigerator, which is conducive to ensuring the refrigeration effect of the refrigerator.

[0110] The refrigerator of the embodiments of the present application can further include a refrigeration system for reducing the air temperature of the storage compartment 11. For example, the refrigeration system can be arranged in the cabinet 10. The refrigeration system can include a compressor, a condenser, a throttling device, and an evaporator connected in a loop.

[0111] When the refrigeration system is operating, the compressor compresses the refrigerant vapor to generate high-temperature and high-pressure refrigerant vapor and delivers the refrigerant vapor to the condenser. The condenser liquefies the high-temperature and high-pressure refrigerant vapor to generate high-temperature and low-pressure refrigerant liquid and delivers the refrigerant liquid to the throttling device. The throttling device reduces the pressure of the refrigerant liquid to convert the high-pressure and low-temperature refrigerant liquid into low-pressure and low-temperature refrigerant liquid and deliver the refrigerant liquid to the evaporator. The evaporator receives the low-pressure and low-temperature refrigerant liquid and causes it to boil under isobaric conditions to absorb heat and vaporize to form refrigerant vapor, thereby reducing the temperature in the storage compartment 11.

[0112] ​Continuing to refer to Figure 3 The refrigerator of the embodiments of the present application can further include a door body 20 rotatably connected to the cabinet 10 by a hinge 30 to open or close the storage compartment 11.

[0113] The door body 20 is connected to the cabinet frame 200 of the cabinet 10 by the hinge 30, so that the door body 20 can rotate relative to the cabinet 10.

[0114] Since the opening of the storage compartment 11 is upward, the door body 20 is located above the cabinet 10, and the door body 20 is rotated upward to open the storage compartment 11, and the door body 20 is rotated downward to close the storage compartment 11.

[0115] In some implementations, the door body 20 can include a door liner. The door liner faces the storage compartment 11 when the door body 20 closes the storage compartment 11.

[0116] The door body 20 can further include a door shell. The door shell can be connected to the outside of the door liner to form the appearance of the door body 20. The door shell is rotatably connected to the cabinet shell 100 by the hinge 30 to open or close the storage compartment 11.

[0117] The door body 20 can further include a door thermal insulation member. The door thermal insulation member can be arranged in the gap between the door liner and the door shell. The door thermal insulation member can insulate the storage compartment 11 to minimize heat exchange between the storage compartment 11 and the outside of the refrigerator, which is conducive to ensuring the refrigeration effect of the refrigerator. The door thermal insulation member can be a foaming layer.

[0118] In Figure 3 , the door body 20 and the cabinet 10 are rotatably connected by two hinges 30. The two hinges 30 are arranged in the left-right direction (corresponding to the X-axis direction in Figure 3 ) of the refrigerator. However, this is not a limitation on the number of hinges 30. The hinge 30 can also be one, or three or more, and the number of hinges 30 is not limited in the embodiments of the present application.

[0119] In combination with Figure 3 and Figure 4 , in some embodiments of the present application, the hinge 30 can include a first hinge seat 300 mounted to the cabinet 10.

[0120] The hinge 30 can further include a second hinge seat 400 rotatably connected to the first hinge seat 300. The second hinge seat 400 is fixed to the door body 20.

[0121] In combination with Figure 5 and Figure 6In some embodiments of this application, the first hinge seat 300 is configured to form a first mounting cavity 301 extending along a first direction, and the first mounting cavity 301 has an opening at one end facing the second hinge seat 400.

[0122] The first direction can be the left or right direction of the freezer, as shown in the reference. Figure 3 In the X-axis direction.

[0123] The hinge 30 may also include an elastic sliding component 500, which is installed in the first mounting cavity 301 and elastically abuts against the first hinge seat 300. The first hinge seat 300 and the second hinge seat 400 can reciprocate relative to each other in the abutting state, thereby realizing the opening and closing of the door 20.

[0124] like Figure 4 As shown, in some possible implementations of this application, the elastic sliding assembly 500 may include: a slider 510, which is disposed within the first mounting cavity 301 and is fixed relative to the first hinge seat 300 in the circumferential direction of the first mounting cavity 301. The slider 510 is configured to slide along the first mounting cavity 301; the slider 510 abuts against the second hinge seat 400 through an opening.

[0125] In some embodiments, such as Figure 7 As shown, a first guide portion 512 along a first direction can be formed on the outer peripheral wall of the slider 510. (Combined) Figure 8 The first hinge seat 300 may be configured to form a second guide portion 311 within the first mounting cavity 301. The second guide portion 311 extends along a first direction. The second guide portion 311 cooperates with the first guide portion 512, so that the slider 510 is relatively fixed to the first hinge seat 300 in the circumferential direction, and the slider 510 is movable along the first direction.

[0126] The first guide portion 512 and the second guide portion 311 can be a combination of a protrusion and a groove, which can extend along a first direction. For example, a groove is formed on the outer peripheral wall of the slider 510, and a protrusion is formed in the first mounting cavity 301. The protrusion and the groove cooperate, allowing the protrusion and the groove to move along the first direction. Forming a protrusion in the first mounting cavity 301, rather than a groove, helps to improve the structural strength of the first hinge seat 300.

[0127] The first guide part 512 and the second guide part 311 can be provided with a plurality of, for example, two, four, etc. In the embodiment of the application, the first guide part 512 and the second guide part 311 can be provided with four, and the four first guide parts 512 are uniformly spaced along the circumference of the sliding piece 510, so that the sliding piece 510 is uniformly stressed when cooperating with the first mounting cavity 301, reducing the possibility that the sliding piece 510 is blocked or even stuck in the first mounting cavity 301.

[0128] In some embodiments of the application, the first hinge seat 300, the second hinge seat 400 and the sliding piece 510 can all be hard plastic pieces, for example, the first hinge seat 300, the second hinge seat 400 and the sliding piece 510 can all be made of wear-resistant materials such as Polyformaldehyde (POM) material and nylon.

[0129] The elastic sliding assembly 500 can further include at least two elastic pieces 530, which provide a force for the abutment of the sliding piece 510 and the second hinge seat 400.

[0130] The at least two elastic pieces 530 are all arranged in the first mounting cavity 301 and located at one end of the sliding piece 510 away from the second hinge seat 400. One end of the elastic piece 530 abuts against the sliding piece 510, and the other end of the elastic piece 530 abuts against one end of the first mounting cavity 301 away from the opening.

[0131] Referring to Figure 9 In some embodiments of the application, a boss 513 is formed at the center of one end of the sliding piece 510 away from the second hinge seat 400, the boss 513 abuts against the elastic piece 530 of the inner ring, and the outer side of the boss 513 abuts against the elastic piece 530 of the outer ring. In this way, the boss 513 is configured on the sliding piece 510 to separate the elastic pieces 530 of the inner ring and the outer ring, reducing the impact between the elastic pieces 530 of the adjacent two rings and affecting the elastic abutting force provided for the sliding piece 510.

[0132] Continuing to refer to Figure 9 A first weight-reducing groove 514 is formed on the sliding piece 510, and the first weight-reducing groove 514 is located between the boss 513 and the outer edge of the sliding piece 510, which can not only reduce the gravity of the sliding piece 510, but also save materials. The first weight-reducing groove 514 can be provided with a plurality of, and the plurality of first weight-reducing grooves 514 are arranged in a circumferential direction of the boss 513, and the ribs between the adjacent two first weight-reducing grooves 514 can play a role in improving the structural strength of the sliding piece 510.

[0133] In some embodiments of the application, the at least two elastic pieces 530 are sequentially sleeved in the radial direction of the first mounting cavity 301. For example, the elastic piece 530 with a larger diameter is sleeved on the outside of the elastic piece 530 with a smaller diameter.

[0134] In Figure 4 some embodiments, the elastic member 530 is a spring, but this is not a limitation to the structure of the elastic member 530. The elastic member 530 can also be other structures with elasticity, such as an elastic rubber tube.

[0135] The hinge 30 of the embodiments of the present application provides sufficient abutting force for the opening and closing of the door body 20 by arranging at least two elastic members 530. Thus, the problem of the door body 20 rapidly falling and causing the door body 20 to violently collide with the cabinet 10 during the closing of the door body 20 can be alleviated. Moreover, the elastic member 530 can provide force for the relative rotation of the first hinge seat 300 and the second hinge seat 400 during the opening of the door body 20, so that the opening of the door body 20 is more labor-saving.

[0136] Of course, in some embodiments, the elastic sliding assembly 500 can also be provided with one elastic member 530 to simplify the structure.

[0137] Continuing to refer to Figure 4 , the hinge 30 of some embodiments of the present application further includes a connecting shaft 600 to assemble the first hinge seat 300, the second hinge seat 400, and the elastic sliding assembly 500.

[0138] As shown in Figure 6 , the sliding member 510 and the elastic member 530 are respectively provided with shaft holes 511, and the connecting shaft 600 is arranged in the shaft holes 511. In the case of the elastic member 530 being a spring, the shaft hole 511 of the elastic member 530 is the internal space of the spiral line of the spring. As shown in Figure 7 and Figure 9 , the center of the sliding member 510 is provided with a through hole to form the shaft hole 511.

[0139] The two ends of the connecting shaft 600 are respectively connected with the first hinge seat 300 and the second hinge seat 400 to relatively fix the first hinge seat 300 and the second hinge seat 400 along the axial direction of the connecting shaft 600. Exemplarily, the first hinge seat 300 and the second hinge seat 400 can be respectively provided with shaft holes 511, so that the two ends of the connecting shaft 600 are arranged in the shaft holes 511.

[0140] In some embodiments, the hinge 30 can further include a gasket 610 provided with a shaft hole 511, so that the connecting shaft 600 is arranged in the gasket 610. The gasket 610 can be arranged at the end of the second hinge seat 400 away from the first hinge seat 300, and the gasket 610 is fixed with the second hinge seat 400 to limit the rotation of the gasket 610 relative to the second hinge seat 400. Of course, the gasket 610 can also be arranged at the end of the first hinge seat 300 away from the second hinge seat 400 to limit the rotation of the gasket 610 relative to the first hinge seat 300.

[0141] Thus, the elastic member 530 and the sliding member 510 are both located in the first mounting cavity 301, and the first hinge seat 300, the second hinge seat 400, the elastic member 530, and the sliding member 510 can be assembled and connected through the connecting shaft 600. The hinge 30 is simple in structure and convenient to assemble, which helps to reduce the installation space occupied by the hinge 30. In addition, the hinge 30 does not need to be additionally provided with a lining plate, which helps to reduce the cost.

[0142] In the embodiments of the present application, the first hinge seat 300 is connected to the second hinge seat 400 through the connecting shaft 600. Figure 10 The second hinge seat 400 is configured to form a second mounting cavity 401, and the second mounting cavity 401 extends along the first direction. Figure 6 The second mounting cavity 401 is open at one end of the second hinge seat 400. Thus, the open end of the second hinge seat 400 is connected to the open end of the first hinge seat 300.

[0143] In some embodiments of the present application, the open end of the first hinge seat 300 is inserted into the second mounting cavity 401, so that a sealed structure is formed between the first hinge seat 300 and the second hinge seat 400, which reduces the possibility of leakage of lubricating oil in the first mounting cavity 301 and the second mounting cavity 401.

[0144] In the embodiments of the present application, the sliding member 510 abuts against the second hinge seat 400. Referring back to Figure 7 A first abutting structure 520 is formed on the sliding member 510. Figure 10 The second hinge seat 400 is configured to form a second abutting structure 410, and the second abutting structure 410 abuts against the first abutting structure 520, so that the sliding member 510 slides along the first direction.

[0145] In some embodiments, as shown in Figure 7 The first abutting structure 520 includes a first curved surface 521 and a third abutting surface 522. The first curved surface 521 can extend along the first direction, and the third abutting surface 522 is arranged at one end of the first curved surface 521 facing the second abutting structure 410.

[0146] As shown in Figure 10 The second abutting structure 410 can include a second curved surface 411 and a fourth abutting surface 412. The second curved surface 411 can extend along the first direction, and the fourth abutting surface 412 is arranged at one end of the second curved surface 411 facing the first abutting structure 520.

[0147] For example, the first curved surface 521 can be a helical surface, and the second curved surface 411 can also be a helical surface.

[0148] The hinge 30 of the embodiments of the present application has a closed state (as shown in Figure 1 and an open state (as shown in Figure 2As shown in FIG. 1, the first hinge seat 300 and the second hinge seat 400 are reciprocally rotated within a certain angular range about an axis extending in the first direction, so that the first abutting structure 520 can slide relative to the second abutting structure 410, thereby switching the hinge 30 between the closed state and the open state.

[0149] When the hinge 30 is in the closed state, the first curved surface 521 abuts against the second curved surface 411, so that the first hinge seat 300 and the second hinge seat 400 have a relative rotating force under the action of the elastic force of the elastic member 530. It can be understood that, under the cooperation of the first curved surface 521 and the second curved surface 411, the elastic force of the elastic member 530 acts on the second curved surface 411 through the first curved surface 521, generating a component force. The component force causes the first hinge seat 300 and the second hinge seat 400 to rotate relative to each other. It can also be understood that the elastic force of the elastic member 530 acts on the second curved surface 411 through the first curved surface 521, causing the second hinge seat 400 to generate a torque relative to the first hinge seat 300. In this way, the opening and closing of the door body 20 can be labor-saving.

[0150] When the hinge 30 is in the open state, the third abutting surface 522 abuts against the fourth abutting surface 412.

[0151] In some embodiments of the present application, the first abutting structure 520 can be provided as a ratchet-like structure. In combination with Figure 7 One end of the sliding member 510 towards the second hinge seat 400 is formed with a plurality of first grooves 523, and the plurality of first grooves 523 are arranged at intervals along the circumference of the sliding member 510. Considering the space and strength, the first grooves 523 can be provided with two, but this is not a limitation on the number of first grooves 523. The wall surface of the side wall of the first groove 523 forms the first curved surface 521, and the end surface of the side wall of the first groove 523 forms the third abutting surface 522. The first groove 523 has a first bottom surface 524.

[0152] The second abutting structure 410 can be provided as a ratchet-like structure. In combination with Figure 10 One end of the second hinge seat 400 towards the sliding member 510 is formed with a plurality of second grooves 413, and the plurality of second grooves 413 are arranged at intervals along the circumference of the second hinge seat 400. Considering the space and strength, the second grooves 413 can be provided with two, but this is not a limitation on the number of first grooves 523. The wall surface of the side wall of the second groove 413 forms the second curved surface 411, and the end surface of the side wall of the second groove 413 forms the fourth abutting surface 412. The second groove 413 has a second bottom surface 414.

[0153] Figure 6 FIG. 1 shows a cross-sectional view of the hinge 30 when the door body 20 is closed. As shown in FIG. 1, the first hinge seat 300 and the second hinge seat 400 are reciprocally rotated within a certain angular range about an axis extending in the first direction, so that the first abutting structure 520 can slide relative to the second abutting structure 410, thereby switching the hinge 30 between the closed state and the open state. Figure 6In the view angle in FIG. 6, when the door body 20 is closed, the third abutting surface 522 abuts against the fourth abutting surface 412, and the sliding member 510 causes the elastic member 530 to be elastically compressed in the left side of the first installation cavity 301. When the door body 20 is opened, the second hinge seat 30 is driven to rotate relative to the first hinge seat 30, the fourth abutting surface 412 rotates relative to the third abutting surface 522, so that the fourth abutting surface 412 is separated from the third abutting surface 522, and the second curved surface 411 abuts against the first curved surface 521; at this time, the elastic member 530 is reset to be elongated, and drives the sliding member 510 to move in the axial direction. In this process, the axial force of the elastic member 530 applied to the sliding member 510 generates a radial tangent force through the cooperation of the first curved surface 521 and the second curved surface 411, which makes the door body 20 have a rotating trend towards the opening direction, so as to balance the gravity of the door body 20 and save the user's opening force.

[0154] When the door body 20 is opened to the maximum opening degree, the side wall of the first groove 523 is inserted into the second groove 413, and the side wall of the second groove 413 is inserted into the first groove 523. The third abutting surface 522 abuts against the second bottom surface 414, and the fourth abutting surface 412 abuts against the first bottom surface 524,

[0155] Continuing to refer to Figure 10 In some embodiments of the present application, the fourth abutting surface 412 is provided with a limiting stopper 415, which is located on the side of the fourth abutting surface 412 away from the connection between the fourth abutting surface 412 and the second curved surface 411. By setting the limiting stopper 415 to abut against the sliding member 510, the second hinge seat 400 is prevented from rotating relative to the first hinge seat 300 beyond the limit position of the closed door body 20.

[0156] In the embodiments of the present application, the first abutting structure 520 and the second abutting structure 410 need to cooperate with sliding, and lubricating oil can be added between the first abutting structure 520 and the second abutting structure 410 to improve the smoothness of the relative sliding of the first abutting structure 520 and the second abutting structure 410 and reduce the wear of the first abutting structure 520 and the second abutting structure 410. For example, in combination with Figure 10 The second curved surface 411 is provided with an oil groove 4111.

[0157] The first installation cavity 301 and the second installation cavity 401 are communicated, and the first hinge seat 300 is provided with an open end inserted into the second installation cavity 401, so that the first installation cavity 301 and the second installation cavity 401 are relatively sealed, and the first abutting structure 520 and the second abutting structure 410 are in a relatively sealed environment, which is beneficial to the storage of lubricating oil and the effectiveness of long-term use.

[0158] In combination with Figure 11 and Figure 12In some embodiments of the present application, the box frame 200 is further configured to form a mounting groove 221, and the opening of the mounting groove 221 faces the door body 20.

[0159] In some possible implementations, the box frame 200 includes a frame body 210 configured to form an opening of the storage compartment 11. Figure 11 In some possible implementations, the frame body 210 is exemplified as a rectangular frame.

[0160] The box frame 200 can further include a fixing body 220 which is an integral part of the frame body 210, so that the structure of the box frame 200 is stable and reliable. The fixing body 220 is located at the rear side of the frame body 210, and the fixing body 220 is used to fix the first hinge seat 300. The fixing body 220 is configured to form a mounting groove 221.

[0161] Continuing to refer to Figure 12 The fixing body 220 includes a first groove side wall 222 and a third groove side wall 224, and the first groove side wall 222 and the third groove side wall 224 are oppositely and spacedly arranged along a second direction. The third groove side wall 224 is closer to the storage compartment 11 relative to the first groove side wall 222. The second direction can be perpendicular to the first direction, and the second direction can correspond to the Y-axis direction in Figure 11

[0162] The first groove side wall 222 can be provided with a second weight-reducing groove 2224, which can not only reduce the weight of the box frame 200, but also reduce the material of the box frame 200.

[0163] The wall surface of the third groove side wall 224 facing the mounting groove 221 is a plane, and the surface of the first fixing part 320 facing the third groove side wall 224 is a plane, which is simple in structure and convenient to process. Through the plane contact between the third groove side wall 224 and the first fixing part 320, the contact area of the first fixing part 320 in the mounting groove 221 is improved, and the stability of the installation of the first fixing part 320 in the mounting groove 221 is improved.

[0164] When a plurality of second weight-reducing grooves 2224 are provided, the plurality of second weight-reducing grooves 2224 are arranged in the axial direction of the hinge 30, and the ribs between the adjacent two second weight-reducing grooves 2224 can improve the structural strength of the first groove side wall 222. The axial direction of the hinge 30 is parallel to the axial direction of the connecting shaft 600 of the hinge 30.

[0165] In some embodiments, the plurality of second weight-reducing grooves 2224 are symmetrically arranged on both sides of the bayonet 2221, so that the structure of both sides of the bayonet 2221 is balanced, which is beneficial to improve the structural stability of the first groove side wall 222.

[0166] ​The fixing body 220 can further include two second slot side walls 223 which are opposite along the axial direction of the hinge 30 and have a spacing. The two second slot side walls 223 are connected with the first slot side wall 222 and the third slot side wall 224 respectively.

[0167] In combination Figures 13 to 15 , the fixing body 220 can further include a slot bottom wall 225 which is connected to the bottom ends of the first slot side wall 222, the two second slot side walls 223 and the third slot side wall 224. In this way, the slot bottom wall 225, the first slot side wall 222, the two second slot side walls 223 and the third slot side wall 224 enclose the mounting slot 221 which is open upward.

[0168] In combination

[0169] In combination Figure 14 and Figure 15 In some embodiments of the present application, the box frame 200 can further include a reinforcing plate 240 which is connected with the fixing body 220 and the frame body 210 respectively to improve the structural strength of the box frame 200.

[0170] In combination Figure 12 and Figure 15 In some embodiments of the present application, the box frame 200 is further configured to form a first clamping portion 230 which is formed on the slot side wall of the mounting slot 221. In combination

[0171] In combination Figure 15 In combination

[0172] In combination Figure 15 In some embodiments of the present application, part of the first hinge seat 300 is connected with the mounting slot 221 in a matching manner, and the first hinge seat 300 is clamped with the first clamping portion 230.

[0173] The part of the first hinge seat 300 is connected with the mounting groove 221, which can be understood as that the part of the first hinge seat 300 is inserted into the mounting groove 221, and the part of the first hinge seat 300 inserted into the mounting groove 221 matches the shape of the mounting groove 221. When the first hinge seat 300 is stressed, the groove side wall of the mounting groove 221 can limit the first hinge seat 300, so that the part of the first hinge seat 300 can be stably inserted into the mounting groove 221.

[0174] In addition, the first hinge seat 300 is clamped with the first clamping part 230, so as to ensure the stability of the connection between the first hinge seat 300 and the cabinet frame 200.

[0175] Therefore, the hinge 30 in the embodiment of the present application, the part of the first hinge seat 300 is connected with the mounting groove 221 of the cabinet frame 200, and the first hinge seat 300 is clamped with the first clamping part 230, so that the mounting mode is stable; no additional fasteners are needed, so that the hinge 30 is simple and efficient to disassemble and assemble. In addition, the part of the first hinge seat 300 is inserted into the mounting groove 221, so that no additional shielding cover for the first hinge seat 300 is needed, which is beneficial to simplify the structure of the hinge 30; in addition, the part of the first hinge seat 300 is embedded into the mounting groove 221, so that the height of the hinge 30 protruding from the cabinet 10 is relatively small, which is helpful to reduce the overall volume of the refrigerator.

[0176] With respect to the clamping of the second hinge seat 400 and the door body 20, in the embodiment of the present application, the part of the first hinge seat 300 is connected with the mounting groove 221 of the cabinet frame 200, and the first hinge seat 300 is clamped with the first clamping part 230, so that the first hinge seat 300 is fixed with the cabinet 10, and the connection is more stable.

[0177] In combination Figure 16 In some embodiments of the present application, the first hinge seat 300 comprises a first hinge part 310, which is rotationally connected with the second hinge seat 400. The first hinge part 310 forms a first mounting cavity 301. Exemplarily, the first hinge part 310 is substantially cylindrical, and the structure is compact.

[0178] The first hinge seat 300 can further comprise a first fixing part 320, which is connected with one side of the first hinge part 310 facing the storage compartment 11 and extends below the first hinge part 310, so that part of the first fixing part 320 is located on the front side of the first hinge part 310, and another part of the first fixing part 320 is located below the first hinge part 310.

[0179] In some embodiments, the first fixing part 320 is integrally formed with the first hinge part 310. Exemplarily, the first fixing part 320 and the first hinge part 310 are formed by injection molding, which is stable in structure and simple to process.

[0180] The part of the first fixing portion 320 is connected with the mounting groove 221, and the part of the first fixing portion 320 below the first hinged portion 310 is connected with the mounting groove 221.

[0181] The first fixing portion 320 is configured to form a second clamping portion 321, and the second clamping portion 321 is clamped with the first clamping portion 230. The part of the first fixing portion 320 inserted into the mounting groove 221 is provided with the second clamping portion 321.

[0182] In the embodiments of the present application, the first hinged seat 300 is rotatably connected with the second hinged seat 400 through the first hinged portion 310, and the part of the first hinged seat 300 is embedded into the mounting groove 221 through the first fixing portion 320 connected with the mounting groove 221. The first fixing portion 320 is integrally formed with the first hinged portion 310, so that the structure of the first hinged seat 300 is stable and reliable. In addition, the first fixing portion 320 forms the second clamping portion 321, and the second clamping portion 321 is clamped with the first clamping portion 230, so that the clamping between the first fixing portion 320 and the cabinet frame 200 is stable and reliable.

[0183] The clamping mode of the first clamping portion 230 and the second clamping portion 321 can be various, for example, the first clamping portion 230 and the second clamping portion 321 can both be clamping hooks, and the clamping of the first clamping portion 230 and the second clamping portion 321 is realized through the clamping of the two clamping hooks. For another example, one of the first clamping portion 230 and the second clamping portion 321 forms a clamping hook, and the other forms a recessed clamping portion, and the clamping of the first clamping portion 230 and the second clamping portion 321 is realized through the clamping of the clamping hook and the clamping portion.

[0184] In some embodiments of the present application, in combination with Figure 12 The mounting groove 221 has a first groove side wall 222 away from the storage compartment 11, and a bayonet 2221 is formed on the first groove side wall 222. In the drawings, the bayonet 2221 penetrates through the thickness direction of the first groove side wall 222, which is convenient for molding. In some embodiments, the bayonet 2221 can be in the form of a groove, in combination with Figure 15 The side of the groove-shaped bayonet away from the third groove side wall 224 forms a groove bottom wall, so that the second clamping portion 321 will not be exposed through the bayonet 2221. Of course, the size of the bayonet 2221 is limited, and the exposure of the second clamping portion 321 through the bayonet 2221 has negligible effect on the appearance of the refrigerator.

[0185] In combination with Figure 15 A first abutting surface 2222 is further formed on the first groove side wall 222; and the first clamping portion 230 comprises the first abutting surface 2222.

[0186] In combination with Figure 15 and Figure 16The first fixed part 320 is formed with a relief gap 322, which provides a deformation interval for the second clamping part 321 to clamp. Figure 15 In the embodiments shown in Figure 16 , the relief gap 322 penetrates the thickness direction of the first fixed part 320, which facilitates the injection molding of the first hinge seat 300. At this time, the interval between the second clamping part 321 and the third slot side wall 224 is the deformation interval of the second clamping part 321. However, this is not restrictive. For example, the relief gap 322 can be in the form of a groove, which is open toward the first slot side wall 222, and the relief gap 322 is formed with a groove bottom wall on the side toward the third slot side wall 224.

[0187] One end of the second clamping part 321 is connected to the side wall of the relief gap 322, and the other end of the second clamping part 321 is configured to form a first mating surface 3211, which abuts with the first abutting surface 2222 along the depth direction of the mounting slot 221.

[0188] In the orientation shown in Figure 15 , the bottom end of the second clamping part 321 is connected to the bottom side wall of the relief gap 322, and the top end of the second clamping part 321 is configured to form the first mating surface 3211.

[0189] In some embodiments of the present application, the second clamping part 321 is a protruding structure arranged on the bottom side wall of the relief gap 322. In combination with Figure 15 , in some embodiments, the cross section of the second clamping part 321 is in the form of an inverted trapezoid, and the end of the second clamping part 321 connected to the bottom side wall of the relief gap 322 has a smaller thickness, which facilitates the deformation of the second clamping part 321 and the installation of the first hinge seat 300. The other end of the second clamping part 321 has a larger thickness, which facilitates the formation of a larger first mating surface 3211, and improves the reliability of the abutment between the first mating surface 3211 and the first abutting surface 2222, thereby improving the stability of the clamping between the first hinge seat 300 and the cabinet frame 200.

[0190] In which, the cross section of the second clamping part 321 is formed by cutting the second clamping part 321 in a plane perpendicular to the axial direction of the hinge 30. The thickness of the second clamping part 321 is the dimension of the second clamping part 321 along the front-rear direction of the refrigerator.

[0191] Of course, this is not a limitation on the shape of the second clamping part 321. As long as one end of the second clamping part 321 can be connected to the side wall of the relief gap 322, and at least part of the other end of the second clamping part 321 extends into the clamping opening 2221 and abuts with the first abutting surface 2222 of the clamping opening 2221.

[0192] In the embodiment of the present application, the second clamping portion 321 extends in the first direction, and the thickness of the second clamping portion 321 gradually increases from the first end toward the second end, which not only helps the molding of the second clamping portion 321, but also helps to improve the structural strength of the second clamping portion 321, ensures that the second clamping portion 321 has a large enough abutting area, and ensures the stability of the clamping. Wherein, the first end of the second clamping portion 321 is connected with the side wall of the avoiding gap 322, and the second end forms the first matching surface 3211.

[0193] The mounting groove 221 of the embodiment of the present application is provided with a clamping opening 2221 and a first abutting surface 2222 on the first groove side wall 222, the first fixing portion 320 is provided with an avoiding gap 322 to provide a setting position for the second clamping portion 321 and provide a space for the deformation of the second clamping portion 321, and the second clamping portion 321 is configured to form a first matching surface 3211, which abuts with the first abutting surface 2222 along the depth direction of the mounting groove 221. The freedom of the first fixing portion 320 along the depth direction of the mounting groove 221 is limited, which helps to improve the stability of the connection between the first hinge seat 300 and the cabinet frame 200.

[0194] Wherein, the depth direction of the mounting groove 221 corresponds to Figure 15 the Z-axis direction, and the Z-axis direction can correspond to the height direction of the refrigerator.

[0195] Continuing to refer to Figure 15 In some embodiments of the present application, the first clamping portion 230 further includes a second abutting surface 2223 formed on the first groove side wall 222. The second abutting surface 2223 and the first abutting surface 2222 are respectively located on both sides of the clamping opening 2221 along the depth direction of the mounting groove 221, so that the second abutting surface 2223 and the first abutting surface 2222 are opposite and have a space, and the space is the clamping opening 2221.

[0196] In combination with Figure 15 and Figure 16 , the part of the first fixing portion 320 located below the avoiding gap 322 is recessed away from the first groove side wall 222 to form a second matching surface 3212. The second matching surface 3212 is opposite to the first matching surface 3211 along the depth direction of the mounting groove 221, and the second matching surface 3212 is located below the first matching surface 3211. The second matching surface 3212 abuts with the second abutting surface 2223 along the depth direction of the mounting groove 221. In this way, the part of the first fixing portion 320 inserted into the mounting groove 221 can be limited, so as to avoid that the insertion depth of the first fixing portion 320 is too large, which affects the abutment of the first abutting surface 2222 and the first matching surface 3211.

[0197] The first fixing portion 320 is located below the avoiding gap 322, is recessed away from the first slot side wall 222, and further forms a first inclined surface 325. Since the portion of the first fixing portion 320 inserted into the mounting slot 221 is connected with the mounting slot 221, the portion of the first slot side wall 222 below the second abutting surface 2223 is recessed towards the inside of the mounting slot 221, forming a second inclined surface 2225. The second inclined surface 2225 is in abutting connection with the first inclined surface 325, and plays a limiting role on the first fixing portion 320.

[0198] In the embodiments of the present application, the first fixing portion 320 is in abutting connection with the first abutting surface 2222 of the first slot side wall 222 through the first matching surface 3211 of the second clamping portion 321, and is in abutting connection with the second abutting surface 2223 along the depth direction of the mounting slot 221 through the second matching surface 3212, so that the second clamping portion 321 and part of the first fixing portion 320 are limited between the first abutting surface 2222 and the second abutting surface 2223, which helps to improve the stability of the first fixing portion 320 clamped in the mounting slot 221, and the installation is simple.

[0199] Continuing to refer to Figure 12 In some embodiments of the present application, the mounting slot 221 has two second slot side walls 223, which are recessed away from each other and respectively form a limiting recessed portion 2231.

[0200] In combination Figure 16 And Figure 17 The first fixing portion 320 forms a limiting protruding portion 323 on both sides along the axial direction of the hinge 30, which is matched with the limiting recessed portion 2231.

[0201] The embodiments of the present application make the first fixing portion 320 connected with the mounting slot 221 through the cooperation of the limiting recessed portion 2231 and the limiting protruding portion 323, limit the first fixing portion 320 along the axial direction of the hinge 30, and further improve the stability and reliability of the first fixing portion 320 inserted into the mounting slot 221.

[0202] Continuing to refer to Figure 16 In some embodiments of the present application, the first hinge seat 300 further comprises a flange 330 connected with the first hinge portion 310. Exemplarily, the flange 330 is integrally formed with the first hinge portion 310, which is stable in structure and convenient to process.

[0203] The flange 330 is opposite to the first fixing portion 320 and has a spacing. When part of the first fixing portion 320 is inserted into the mounting slot 221, the flange 330 is located outside the mounting slot 221. The side of the flange 330 away from the first fixing portion 320 forms a first limiting portion 331.

[0204] In combination Figure 10The second limiting portion 440 is formed on the second hinge seat 400 and is configured to abut against the first limiting portion 331 when the door body 20 is opened, so as to limit the opening angle of the door body 20 and avoid damage to the hinge 30 caused by the opening angle of the door body 20 exceeding the limit opening position.

[0205] The first limiting portion 331 and the second limiting portion 440 can be a matching structure of a recess and a protrusion. One of the first limiting portion 331 and the second limiting portion 440 forms a recess, and the other forms a protrusion. The abutment and limiting of the second limiting portion 440 and the first limiting portion 331 are achieved by matching the protrusion and the recess.

[0206] In combination with Figure 15 and Figure 16 In some embodiments of the present application, the flange 330 is provided with a limiting surface 332 on one side facing the first fixed portion 320. The limiting surface 332 is configured to abut against the top of the mounting groove 221 when the door body 20 is opened. In the embodiments of the present application, the limiting surface 332 is configured to abut against the top of the first groove side wall 222 when the door body 20 is opened, so as to limit the first fixed portion 320 and reduce the possibility of the first fixed portion 320 being pulled out of the mounting groove 221.

[0207] For example, the limiting surface 332 can be a curved surface, which is not only easy to form, but also makes the connection between the flange 330 and the first hinge portion 310 relatively smooth, which helps to reduce stress concentration. Correspondingly, the top of the first groove side wall 222 is provided with a curved surface matching the limiting surface 332.

[0208] For example, Figure 16 In some embodiments, the first fixed portion 320 is provided with a third weight-reducing groove 324, which can not only reduce the weight of the hinge 30, but also reduce the material used for the first hinge seat 300.

[0209] When a plurality of third weight-reducing grooves 324 are provided, the plurality of third weight-reducing grooves 324 are arranged in the axial direction of the hinge 30, and the ribs between adjacent two third weight-reducing grooves 324 can improve the structural strength of the first fixed portion 320.

[0210] In some embodiments, the plurality of third weight-reducing grooves 324 are symmetrically arranged on both sides of the avoiding gap 322, so that the structures on both sides of the avoiding gap 322 are balanced, which helps to improve the structural stability of the first hinge seat 300.

[0211] In some embodiments of the present application, in combination with Figure 18 and Figure 19The box shell structure forms a mounting port 121 through the thickness of the box shell. In the embodiments of the present application, the rear side plate 120 of the box shell forms the mounting port 121. The top of the mounting port 121 is open, such that the top of the mounting port 121 extends to the top edge of the box shell 100. In this way, the mounting port 121 is substantially U-shaped.

[0212] The mounting port 121 is used to cooperate with the fixing body 220. The edge of the mounting port 121 is inwardly bent to form a flange 122. The corners of the flange 122 are formed with stress notches to avoid stress concentration and cracking of the flange 122.

[0213] In combination Figure 20 and Figure 21 The flange 122 is in abutting cooperation with the fixing body 220, such that the fixing body 220 is relatively sealed with the rear side plate 120 of the box shell 100, without the need for additional sealing structure, which can avoid leakage of foaming material when foaming to form the box thermal insulation layer between the box shell 100 and the box liner, and facilitate the simplification of the structure of the refrigerator.

[0214] In some embodiments, the groove bottom wall 225 of the fixing body 220 is recessed towards the direction of the slot opening of the mounting groove 221 away from one end of the first groove side wall 222, to form a recessed cooperation part, which includes a first wall part 2251 and a second wall part 2252. The first wall part 2251 can be parallel to the groove bottom wall 225, and the end of the first wall part 2251 away from the second wall part 2252 is connected to the first groove side wall 222. The inner wall surface of the first wall part 2251 located in the mounting groove 221 is part of the second abutting surface 2223. The second wall part 2252 connects the first wall part 2251 and the groove bottom wall 225. The inner wall surface of the second wall part 2252 located in the mounting groove 221 forms a second inclined surface 2225.

[0215] The fixing body 220 can further include an extension edge 226 connected below the first wall part 2251 and opposite to the second wall part 2252 with a spacing. The part of the rear side plate 120 is in abutting cooperation with the extension edge 226, and the flange 122 is in abutting cooperation with the outer wall surface of the first wall part 2251 of the fixing body 220, such that a bent cooperation surface is formed between the box shell 100 and the fixing body 220, to improve the sealing of the cooperation between the box shell 100 and the fixing body 220.
