Description

TECHNICAL FIELD

[0001] The disclosure relates to a refrigerator. BACKGROUND

[0002] In general, a refrigerator is a home appliance that can store food at a low temperature in an internal storage space shielded by a door. Specifically, the refrigerator can cool the inside of the storage space by using cool air generated by heat exchange with a refrigerant that circulates a refrigeration cycle, thereby storing the stored food in an optimal state.

[0003] With changes in eating habits and a trend toward higher quality products, recent refrigerators are becoming larger and more functional, and are being released in various structural forms that consider user convenience.

[0004] For example, recently, refrigerators are built into walls or are configured to be arranged in harmony with other furniture or home appliances. At this time, in order to prevent the corners of the rotating door of the refrigerator from interfering with adjacent components such as walls, furniture, or home appliances, a certain separation distance is required between the refrigerator and the adjacent components. However, the required separation distance not only creates unnecessary space, but also causes an aesthetic problem.

[0005] To solve these problems, a multi-link hinge device that allows the door of the refrigerator to rotate without interfering with adjacent components has recently been developed.

[0053] Hereinafter, a specific embodiment of the present disclosure will be described in detail with reference to the accompanying drawings. However, the present disclosure is not limited to the embodiments presented in the spirit of the present disclosure, and other embodiments of the present disclosure or other embodiments within the scope of the spirit of the present disclosure can be easily presented by adding, changing, deleting, etc. other components.

[0054] Before explanation, directions are defined. In the embodiments of the present disclosure, in which the front surface of a door as shown in Figure 1 and Figure 2 faces, the direction based on which the front surface of the door faces toward a cabinet can be defined as a rear direction, the direction toward a floor surface on which the refrigerator is installed can be defined as a lower direction, and the direction away from the floor surface can be defined as an upper direction. Further, when one direction is not defined, it can be explained by defining the direction based on each drawing.

[0055] Although the embodiments of the present disclosure describe a refrigerator in which a refrigerating chamber and a freezing chamber are arranged vertically and each has a door, it should be noted in advance that the present disclosure is not limited to the structure and shape of the refrigerator, and can be applied to all types of refrigerators having a rotating door.

[0056] Figure 1 is a front view illustrating a refrigerator according to one embodiment. Figure 2 is a perspective view illustrating a refrigerator according to one embodiment with a door opened.

[0057] Referring to Figure 1 and Figure 2According to one embodiment, the refrigerator 1 can include a cabinet 10 forming a storage space having an open front surface, and a door 20 for opening and closing the storage space. The cabinet 10 and the door 20 can form the overall appearance of the refrigerator 1.

[0058] According to one embodiment, the refrigerator 1 can be installed in coordination with a wall O of furniture or an indoor space. For example, as shown in FIG. 1, the refrigerator 1 can be installed in an indoor space such as a kitchen, and can be disposed in coordination with furniture or a wall O. Figure 1

[0059] In the disposition structure of the refrigerator 1 as described above, the front surface of the refrigerator 1, in other words, the front surface of the door 20 can be very close to the furniture or the wall O, and can be configured to be positioned on the same or a close plane to have a sense of unity. In some cases, the front surface of the door 20 can be provided with a panel formed of the same material as the furniture or the wall O or a material having the same texture, so that the front surface of the refrigerator 1 can have a greater sense of unity with the adjacent furniture or wall O.

[0060] In detail, observing the structure of the refrigerator 1, the cabinet 10 can form a vertically partitioned storage space 11. For example, the cabinet 10 can be vertically partitioned by a partition 14. The cabinet 10 can form an upper storage space 11 located above the partition 14 and a lower storage space (not shown) located below the partition 14.

[0061] For example, the refrigerator 1 according to one embodiment can be configured as a bottom freezer type. In other words, the upper storage space 11 of the refrigerator 1 can be used as a refrigerating chamber, and the lower storage space can be used as a freezing chamber. Accordingly, the upper storage space 11 can be referred to as a refrigerating chamber, and the lower storage space can be referred to as a freezing chamber.

[0062] The door 20 can include an upper door 21 opening and closing the upper storage space 11 and a lower door 22 opening and closing the lower storage space.

[0063] The upper door 21 can be rotatably installed on the cabinet 10. The upper door 21 can open and close the upper storage space 11 by rotation. The upper door can be connected to the cabinet 10 by first and second hinges 30 and 40 coupled to upper and lower ends of the upper door 21, respectively.

[0064] The upper door 21 can be provided in a pair on the left and right sides. The pair of upper doors 21 can be configured to be independently rotatable to open and close the upper storage space 11.

[0065] For example, the upper door 21 can include an upper cap trim 211 forming an upper surface, a lower cap trim 212 forming a lower surface, a side trim 213 forming a side surface, a door inner liner 214 forming a rear surface, and a front panel 215 forming a front surface (see FIG. 2).​Figure 4 ).

[0066] The first hinge 30 can be coupled to an upper end of the upper door 21, and the second hinge 40 can be coupled to a lower end. For example, the first hinge 30 can be coupled to an upper cap trim 211 of the upper door 21, and the second hinge 40 can be coupled to a lower cap trim 212 of the upper door 21. The upper door 21 can be rotatably connected to the cabinet 10 through the first hinge 30 and the second hinge 40.

[0067] Meanwhile, the first hinge 30 and the second hinge 40 can rotate along the same trajectory, and the upper door 21 and the lower door 22 can smoothly rotate without interference with adjacent furniture or a wall O during the opening and closing processes.

[0068] The refrigerator 1 according to one embodiment can further include a first hinge cover 15 installed on an upper surface of the cabinet 10. For example, the first hinge cover 15 is disposed on the upper surface of the front end of the cabinet 10, and can partially shield the first hinge 30.

[0069] Meanwhile, the lower door 22 can be configured as a drawer-type door that can be pulled in and pulled out. However, the disclosure is not limited thereto, and the lower door 22 can be rotatably installed on the cabinet 10 by hinges respectively disposed at upper and lower ends in the same manner as the upper door 21, thereby opening and closing the lower storage space.

[0070] Figure 3 and Figure 4 is a partial perspective view showing a mounted state of a first hinge of a refrigerator according to one embodiment.

[0071] Referring to Figure 3 and Figure 4 , the first hinge 30 can be installed on an upper end of a front surface of the cabinet 10. The first hinge 30 can be installed at a position adjacent to a side surface from the upper end of the front surface of the cabinet 10. The first hinge 30 can be connected to an upper end of a rear surface of the upper door 21.

[0072] The upper door 21 can include a hinge installation portion 21a on which the first hinge 30 is installed. The hinge installation portion 21a can be formed by being recessed downward through an upper surface of the upper door 21. The hinge installation portion 21a can also be regarded as being formed by being recessed forward through a rear surface of the upper door 21. For example, the hinge installation portion 21a can be formed in the upper cap trim 211. In other words, the hinge installation portion 21a can be formed by being partially recessed through the upper cap trim 211.

[0073] The upper door 21 can include a bottom portion 2111 forming a bottom surface of the hinge mounting portion 21a and a first recessed portion 2112 formed by being more recessed than the bottom portion 2111. For example, the upper cap trim 211 can include the bottom portion 2111 forming a bottom surface of the hinge mounting portion 21a and the first recessed portion 2112. The bottom portion 2111 can be formed around the first recessed portion 2112. As will be described later, the first hinge 30 can be mounted on the first recessed portion 2112.

[0074] The upper cap trim 211 can include a cap trim opening 211a (see Figure 8 ) formed in front of the first hinge 30. The cap trim opening 211a can be shielded by the front panel 215.

[0075] The cabinet 10 can include a first cabinet bracket 12 disposed on the upper end of the front surface. The first hinge 30 can be mounted on the first cabinet bracket 12. For example, the first cabinet bracket 12 can be coupled to the first hinge cover 15 via the fastening member 311a.

[0076] The first hinge 30 can have a multi-link hinge structure in which a plurality of links are coupled. A rotation trajectory of the upper door 21 can be determined by the plurality of link structures constituting the first hinge 30. For example, through the first hinge 30, the upper door 21 can implement a trajectory that does not interfere with other upper doors 21 disposed side by side and furniture or a wall O disposed to the side. Accordingly, the first hinge 30 can be referred to as a multi-link hinge.

[0077] The first hinge 30 can include a first upper hinge bracket 31 mounted on the cabinet 10, a second upper hinge bracket 35 connected to the upper door 21, a first mounting bracket 36 mounting the second upper hinge bracket 35 to the upper door 21, and a plurality of links 32, 33, 34 disposed between the first upper hinge bracket 31 and the second upper hinge bracket 35.

[0078] The first upper hinge bracket 31 can be formed in the shape of a metal plate, and the upper surface and the lower surface can be bent to form an accommodation space capable of accommodating the plurality of links described later.

[0079] The first upper hinge bracket 31 can include a first base portion 311 fixed in contact with the cabinet 10, a first extension portion 312 formed by extending forward from the upper end and the lower end of the first base portion 311, and a first side portion 313 extending forward from the side end of the first base portion 311.

[0080] The first base 311 can be installed on the front surface of the cabinet 10. The first base 311 is formed in a plate shape, and can be positioned to face the front surface of the cabinet 10. The first base 311 can be fixed to the front surface of the upper end of the cabinet 10 by a fastening member 311a. For example, the first base 311 can be fixed to the first cabinet bracket 12 installed on the upper surface of the cabinet 10 and installed on the front surface of the cabinet 10.

[0081] The first extension 312 can be bent perpendicularly to the first base 311, and can extend forward. The first extension 312 can be configured as a pair spaced apart from each other. The first extension 312 can extend forward from the upper end and the lower end of the first base 311, respectively.

[0082] Rotary shafts 314, 315 to which the first link 32 and the third link 34 are rotatably connected can be coupled to the first extension 312. The rotary shafts 314, 315 to which the first link 32 and the third link 34 are rotatably connected can be coupled by penetrating a pair of first extensions 312. In this specification, the rotary shafts can not only refer to an imaginary shaft that becomes the center of rotation of a rotating object, but also refer to a configuration that forms the center of rotation.

[0083] The first side 313 can extend forward from the side end of the first base 311. The first side 313 can connect a pair of first extensions 312. For example, the upper end and the lower end of the first side 313 can be coupled to a pair of first extensions 312, respectively. The first side 313 can maintain a separation distance between the pair of first extensions 312. Through the above structure, the first side 313 can strengthen the structure so that the first upper hinge bracket 31 can support the load of the upper door 21.

[0084] As described above, the first hinge 30 can include a plurality of links 32, 33, 34 disposed between the first upper hinge bracket 31 and the second upper hinge bracket 35. Each of the links 32, 33, 34 can be axially coupled to form an overall quadrilateral shape, and can provide a trajectory along which the upper door 21 can rotate by folding or unfolding.

[0085] The first link 32 can be axially coupled to the first upper hinge bracket 31 and the second link 33, respectively. For example, one end of the first link 32 can be axially coupled to the first upper hinge bracket 31 via the first rotary shaft 314, and the other end can be axially coupled to the second link 33 via the second rotary shaft 321.

[0086] The second link 33 can be axially coupled to the first link 32 and the second upper hinge bracket 35, respectively. For example, one end of the second link 33 can be axially coupled to the first link 32 via a second rotation axis 321, and the other end can be axially coupled to the second upper hinge bracket 35 via a third rotation axis 353.

[0087] The second link 33 can be provided with a spring (not shown) that is stretched or compressed according to rotation of the second link 33, and forces the second link 33 to rotate. The spring can be located inside the second link 33. For example, the spring can be a compression spring or a tension spring. The spring can be compressed during the process of closing the upper door 21, and just before the upper door 21 is closed, it can be restored.

[0088] The third link 34 can be axially coupled to the first upper hinge bracket 31 and the second upper hinge bracket 35, respectively. For example, one end of the third link 34 can be axially coupled to the first link 32 via a fourth rotation axis 322, and the other end can be axially coupled to the second upper hinge bracket 35 via a fifth rotation axis 354.

[0089] Although not shown, the first upper hinge bracket 31 and the third link 34 can be connected by a linear damper (not shown) to which both ends thereof are axially coupled. In other words, the third link 34 can be connected to a sixth rotation axis 315 of the first upper hinge bracket 31 via the linear damper (not shown). For example, one end of the linear damper can be rotatably axially coupled to the sixth rotation axis 315, and the other end thereof can be coupled to the third link 34. The other end of the linear damper can be coupled to a position between one end and the other end of the third link 34. When the first hinge 30 is folded, that is, when the upper door 21 is closed, the linear damper can reduce rotation and alleviate impact.

[0090] By the action of the linear damper and the spring, the plurality of links 32, 33, 34 constituting the first hinge 30 can be rotated while maintaining a set trajectory.

[0091] The second upper hinge bracket 35 can be formed in the shape of a metal plate, and the upper surface and the lower surface can be bent to form an accommodation space capable of accommodating a plurality of links described later.

[0092] The second upper hinge bracket 35 can include a second base 351 facing the rear surface of the upper door 21, and a second extension 352 formed to extend rearward from the upper end and the lower end of the second base 351.

[0093] The second base 351 is formed in a plate shape, and can be disposed to face a rear surface of the upper door 21. For example, the second base 351 can be disposed to face a rear surface of a front surface of the upper door 21 forming the hinge mounting portion 21a. The second base 351 can be disposed to face one surface of a front surface of the upper cap trim 211 forming the hinge mounting portion 21a.

[0094] The second extension 352 can be bent perpendicularly to the second base 351, and can extend rearward. The second extension 352 can be configured as a pair spaced apart from each other. The second extension 352 can include a second upper extension 352a extending rearward from an upper end of the second base 351 and a second lower extension 352b extending rearward from a lower end.

[0095] Rotary shafts 353, 354 to which the second link 33 and the third link 34 are rotatably connected can be coupled to the second extension 352. The rotary shafts 353, 354 to which the second link 33 and the third link 34 are rotatably connected can be coupled by penetrating a pair of the second extensions 352. For example, a third rotary shaft 353 to which the other end of the second link 33 is coupled and a fifth rotary shaft 354 to which the other end of the third link 34 is coupled can be coupled to the second extension 352. For example, the third rotary shaft 353 and the fifth rotary shaft 354 can be configured as a rivet.

[0096] The first mounting bracket 36 can be disposed at a lower portion of the second upper hinge bracket 35. The first mounting bracket 36 can fix the second upper hinge bracket 35 to the upper door 21. For example, the first mounting bracket 36 can be mounted to the first recess 2112 of the upper door 21. An upper end of the first mounting bracket 36 is coupled to the second upper hinge bracket 35, and a lower end thereof is coupled to the first recess 2112 of the upper door 21, thereby mounting the second upper hinge bracket 35 to the upper door 21. For example, the first mounting bracket 36 can be made of a metal material.

[0097] First, detailed structures of the first mounting bracket 36 will be described with reference to Figure 5 and Figure 6

[0098] Figure 5 FIG. 17 is a perspective view illustrating a first mounting bracket according to an embodiment. Figure 6 FIG. 18 is a plan view illustrating the first mounting bracket according to an embodiment.

[0099] Referring to Figure 5 and Figure 6 ​A detailed structure of the first mounting bracket 36 will be described. The first mounting bracket 36 can include a first mounting portion 361 mounted on the upper door 21, a second mounting portion 362 mounted on the second upper hinge bracket 35, and a connection portion 363 connecting the first mounting portion 361 and the second mounting portion 362.

[0100] The first mounting portion 361 can have a square plate shape extending in one direction. For example, the first mounting portion 361 can have a square plate shape having a first width w1 in a longitudinal direction in which it extends, and a second width w2 smaller than the first width w1 in a width direction intersecting the longitudinal direction.

[0101] The first mounting portion 361 can include a first fastening hole 361a to which the fastening member 37 is fastened. A plurality of first fastening holes 361a of the first mounting portion 361 can be formed. For example, a pair of first fastening holes 361a can be formed, and the pair of first fastening holes can be formed at one end portion and the other end portion of the first mounting portion 361, respectively. In addition, the first fastening hole 361a can be disposed not to overlap the second mounting portion 362.

[0102] Meanwhile, the first mounting portion 361 can further include a jig hole 361b positioned below the second fastening hole 362a. The jig hole 361b can be formed to allow the third rotating shaft 353 and the fifth rotating shaft 354 to pass through the second fastening hole 362a and the third fastening hole 362b, respectively. For example, the jig hole 361b can be disposed to place a jig required to rivet the third rotating shaft 353 and the fifth rotating shaft 354.

[0103] The second mounting portion 362 can be formed to be spaced apart from the first mounting portion 361. The second mounting portion 362 can have a plate shape extending in one direction. As will be described later, the second mounting portion 362 can be mounted on the second lower extension portion 352b of the second upper hinge bracket 35.

[0104] The second mounting portion 362 can have a shape corresponding to the second lower extension portion 352b of the second upper hinge bracket 35. For example, an end portion shape of the second mounting portion 362 can have a shape corresponding to the second lower extension portion 352b of the second upper hinge bracket 35. In this way, the second mounting portion 362 can stably support the second upper hinge bracket 35.

[0105] The second mounting portion 362 can have a third width w3 in a longitudinal direction in which it extends, and a fourth width w4 smaller than the third width w3 in a width direction intersecting the longitudinal direction.

[0106] Meanwhile, a third width w3, which is a longitudinal width of the second mounting portion 362, can be smaller than a first width w1, which is a longitudinal width of the first mounting portion 361. Also, a fourth width w4, which is a width of the second mounting portion 362 in a width direction, can be smaller than a second width w2, which is a width of the first mounting portion 361 in the width direction. An area of one side of the second mounting portion 362 can be smaller than an area of one side of the first mounting portion 361. Also, in a plan view, the second mounting portion 362 can be positioned inside the first mounting portion 361. In other words, in a plan view, an edge of the second mounting portion 362 can be positioned inside an edge of the first mounting portion 361.

[0107] Through the above-described structure, the second mounting portion 362 can be configured to stably support the second upper hinge bracket 35 during the opening and closing of the upper door 21, while not interfering with the front end of the first extension portion 312 of the first upper hinge bracket 31.

[0108] The second mounting portion 362 can include a plurality of fastening holes 362a, 362b. For example, the second mounting portion 362 can include a second fastening hole 362a through which the third rotating shaft 353 passes and a third fastening hole 362b through which the fifth rotating shaft 354 passes. The second fastening hole 362a and the third fastening hole 362b can be formed between the pair of first fastening holes 361a.

[0109] The connection portion 363 of the first mounting bracket 36 can connect the first mounting portion 361 and the second mounting portion 362. The connection portion 363 can connect one end of the first mounting portion 361 and one end of the second mounting portion 362. The connection portion 363 can be formed in a convexly curved shape facing the front. A lower end of the connection portion 363 can be connected to one end of the first mounting portion 361, and an upper end thereof can be connected to one end of the second mounting portion 362. The first mounting portion 361 can extend from the lower end of the connection portion 363 to the other side, and the second mounting portion 362 can extend from the upper end of the connection portion 363 to the other side.

[0110] Due to the convexly curved shape of the connection portion 363, a load applied to the first mounting portion 361 or the second mounting portion 362 can be distributed. Thus, due to the shape of the connection portion 363, stability of the coupling between the upper door 21 and the second upper hinge bracket 35 through the first mounting bracket 36 can be improved.

[0111] The first mounting bracket 36 can further include a bracket support portion 364 formed at the upper end of the connection portion 363. The bracket support portion 364 can be positioned at one side of the second mounting portion 362. The bracket support portion 364 can extend upward from the upper end of the connection portion 363.

[0112] Hereinafter, a description will be given with reference to Figures 7 to 10A detailed description of the coupling structure between the first hinge 30 and the upper door 21.

[0113] Figure 7 is an exploded perspective view showing the coupling structure of the first hinge and the upper door in the refrigerator according to one embodiment. Figure 8 is a cross-sectional view taken along Figure 4 line 8-8 of FIG. 8. Figure 9 is a cross-sectional view taken along Figure 4 line 9-9 of FIG. 9. Figure 10 is a cross-sectional view taken along Figure 4 line 10-10 of FIG. 10.

[0114] Referring to Figures 7 to 10 , the first mounting portion 361 of the first mounting bracket 36 can be installed in the first recessed portion 2112 of the upper door 21. For example, the first mounting portion 361 can be installed in the first recessed portion 2112 formed in the upper cap trim 211. The first mounting portion 361 can be fixedly installed in the first recessed portion 2112 by the fastening member 37 inserted into the first fastening hole 361a.

[0115] The first recessed portion 2112 can include a recessed fastening hole 2112a that is open in the vertical direction. The fastening member 37 can be fastened by penetrating the first fastening hole 361a of the first mounting portion 361 and the recessed fastening hole 2112a of the first recessed portion 2112. Accordingly, the first mounting portion 361 can be fixedly installed to the first recessed portion 2112 of the upper door 21. In other words, by the above-described structure, the first mounting portion 361 can be fixedly installed to the first recessed portion 2112 of the upper door 21 in the vertical direction.

[0116] A fixing bracket 38 to which the fastening member 37 is fastened can be provided on a lower surface of the first recessed portion 2112. The fixing bracket 38 can be provided on an opposite side of the first mounting bracket 36, with the first recessed portion 2112 positioned between the fixing bracket 38 and the first mounting bracket 36. The fixing bracket 38 and the first mounting bracket 36 can be fastened to each other by the fastening member 37. The fixing bracket 38 can include a boss portion to which the fastening member 37 is fastened. For example, the fixing bracket 38 can be made of a metal material. Accordingly, by fastening the fastening member 37 to the fixing bracket 38, the first mounting bracket 36 can be firmly installed to the first recessed portion 2112.

[0117] The second mounting portion 362 can be installed on the second lower extension portion 352b of the second upper hinge bracket 35. The second mounting portion 362 can be positioned at a lower portion of the second lower extension portion 352b.

[0118] The third rotating shaft 353 can extend to a lower portion of the second lower extension 352b and be fixed by passing through the second fastening hole 362a. The fifth rotating shaft 354 can extend to the lower portion of the second lower extension 352b and be fixed by passing through the third fastening hole 362b. In other words, the second lower extension 352b and the second mounting portion 362 can be fixed by the third rotating shaft 353 and the fifth rotating shaft 354.

[0119] The second upper hinge bracket 35 is mounted on the second mounting portion 362, and the first mounting portion 361 is mounted on the first recessed portion 2112, so that the second upper hinge bracket 35 can be mounted on the upper door 21 by the first mounting bracket 36.

[0120] Meanwhile, the bracket support portion 364 can support a rear side of the second base 351 of the second upper hinge bracket 35. Through the above-described structure, when the upper door 21 rotates, the bracket support portion 364 of the first mounting bracket 36 presses the second base 351, so that stress applied to the third rotating shaft 353 and the fifth rotating shaft 354 can be dispersed.

[0121] Hereinafter, the mounting structure of the second hinge 40 will be described with reference to Figures 11 to 14

[0122] Figures 11 to 13 FIG. 14 is a partial perspective view showing a mounting state of the second hinge of the refrigerator according to one embodiment. Figure 14 Figure 12 is a cross-sectional view taken along line 14-14 of

[0123] Referring to Figures 11 to 14 , the second hinge 40 can be mounted on a front surface of the partition 14 of the cabinet 10. The second hinge 40 can be connected to a lower end of a rear surface of the upper door 21.

[0124] The upper door 21 can include a lower portion 2121 forming a lower surface and a second recessed portion 2122 formed by being recessed upward from the lower portion 2121. For example, a lower cap trim 212 can include the lower portion 2121 and the second recessed portion 2122. The lower portion 2121 can be formed around the second recessed portion 2122. As will be described later, the second hinge 40 can be mounted on the second recessed portion 2122.

[0125] The cabinet 10 can include a second cabinet bracket 16 disposed on an upper end of the front surface. The second cabinet bracket 16 can be equipped with the second hinge 40.

[0126] ​​The second hinge 40 can have a multi-link hinge structure in which a plurality of links are coupled. A rotational trajectory of the upper door 21 can be determined by the plurality of link structures constituting the second hinge 40. For example, through the second hinge 40, the upper door 21 can implement a trajectory that does not interfere with other upper doors 21 disposed side by side and furniture or a wall O disposed to the side. Accordingly, the second hinge 40 can be referred to as a multi-link hinge.

[0127] The second hinge 40 can include a first lower hinge bracket 41 installed on the partition 14, a second lower hinge bracket 45 positioned at a lower portion of the upper door 21, a second installation bracket 46 installing the second lower hinge bracket 45 to a lower surface of the upper door 21, and a plurality of links 42, 43, 44 disposed between the first lower hinge bracket 41 and the second lower hinge bracket 45.

[0128] The first lower hinge bracket 41 can be formed in the shape of a metal plate, and the upper surface and the lower surface can be bent to form an accommodation space capable of accommodating the plurality of links described later.

[0129] The first lower hinge bracket 41 can include a first base 411 fixed in contact with the cabinet 10, a first extension 412 formed by extending forward from upper and lower ends of the first base 411, and a first side 413 extending forward from side ends of the first base 411.

[0130] The first base 411 can be installed on the front surface of the cabinet 10. The first base 411 is formed in a plate shape, and can be positioned to face the front surface of the partition 14. The first base 411 can be fixed to the front surface of the partition 14 by a fastening member 411a. For example, the first base 411 can be fixed to the second cabinet bracket 16 installed on the partition 14 and installed on the front surface of the cabinet 10.

[0131] The first extension 412 can be bent perpendicular to the first base 411, and can extend forward. The first extension 412 can be configured as a pair spaced apart from each other. The first extension 412 can extend forward from the upper end and the lower end of the first base 411, respectively.

[0132] Rotary shafts 414, 415 to which the first link 42 and the third link 44 are rotatably connected can be coupled to the first extension 412. The rotary shafts 414, 415 to which the first link 42 and the third link 44 are rotatably connected can be coupled by passing through the pair of first extensions 412. In this specification, the rotary shaft can not only refer to an imaginary shaft that becomes the center of rotation of a rotating object, but also refer to a configuration that forms the center of rotation.

[0133] The first side portion 413 can extend forward from a side end of the first base portion 411. The first side portion 413 can connect a pair of first extension portions 412. For example, upper and lower ends of the first side portion 413 can be coupled to the pair of first extension portions 412, respectively. The first side portion 413 can maintain a separation distance between the pair of first extension portions 412. Through the above-described structure, the first side portion 413 can strengthen the structure so that the first lower hinge bracket 41 can support a load of the upper door 21.

[0134] As described above, the second hinge 40 can include a plurality of links 42, 43, 44 disposed between the first lower hinge bracket 41 and the second lower hinge bracket 45. Each of the links 42, 43, 44 can be axially coupled to form an overall quadrilateral shape, and can provide a trajectory along which the upper door 21 can rotate by being folded or unfolded.

[0135] The first link 42 can be axially coupled to the first lower hinge bracket 41 and the second link 43, respectively. For example, one end of the first link 42 can be axially coupled to the first lower hinge bracket 41 via a first rotation axis 414, and the other end thereof can be axially coupled to the second link 43 via a second rotation axis 421.

[0136] The second link 43 can be axially coupled to the first link 42 and the second lower hinge bracket 45, respectively. For example, one end of the second link 43 can be axially coupled to the first link 42 via the second rotation axis 421, and the other end thereof can be axially coupled to the second lower hinge bracket 45 via a third rotation axis 453.

[0137] The second link 43 can be provided with a spring (not shown) that is stretched or compressed according to rotation of the second link 43 and forces the second link 43 to rotate. The spring can be located inside the second link 43. For example, the spring can be a compression spring or a tension spring. The spring can be compressed during a process of closing the upper door 21 and just restored before the upper door 21 is closed.

[0138] The third link 44 can be axially coupled to the first lower hinge bracket 41 and the second lower hinge bracket 45, respectively. For example, one end of the third link 44 can be axially coupled to the first link 42 via a fourth rotation axis 422, and the other end thereof can be axially coupled to the second lower hinge bracket 45 via a fifth rotation axis 454.

[0139] Although not shown, the first lower hinge bracket 41 and the third link 44 can be connected by a linear damper (not shown) to which both ends thereof are axially coupled. In other words, the third link 44 can be connected to the sixth rotation axis 415 of the first lower hinge bracket 41 via the linear damper (not shown). For example, one end of the linear damper can be rotatably axially coupled to the sixth rotation axis 415, and the other end thereof can be coupled to the third link 44. The other end of the linear damper can be coupled to a position between one end and the other end of the third link 44. When the second hinge 40 is folded, that is, when the upper door 21 is closed, the linear damper can reduce rotation and mitigate impact.

[0140] By the action of the linear damper and the spring, the plurality of links 42, 43, 44 constituting the second hinge 40 can be rotated while maintaining a set trajectory.

[0141] The second lower hinge bracket 45 can be formed in the shape of a metal plate, and the upper surface and the lower surface can be bent to form an accommodation space capable of accommodating a plurality of links described later.

[0142] The second lower hinge bracket 45 can include a second base 451 facing the rear surface of the upper door 21 and a second extension 452 formed to extend forward from the upper end and the lower end of the second base 451.

[0143] Meanwhile, the upper door 21 can further include a second hinge cover 216 extending downward from the lower cap trim 212. The second hinge cover 216 can cover the second hinge 40 from the front. In this way, the second hinge cover 216 can prevent the second hinge 40 from being exposed from the front. For example, the second hinge cover 216 can be coupled to the lower cap trim 212. The second hinge cover 216 can be positioned in front of the second lower hinge bracket 45.

[0144] The second base 451 is formed in a plate shape and can be positioned at a lower portion of the lower cap trim 212. For example, the second base 451 can be positioned to face the rear surface of the second hinge cover 216.

[0145] The second extension 452 can be bent perpendicular to the second base 451 and can extend rearward. The second extension 452 can be configured as a pair spaced apart from each other. The second extension 452 can include a second upper extension 452a extending rearward from the upper end of the second base 451 and a second lower extension 452b extending rearward from the lower end.

[0146] The rotating shafts 453, 454 to which the second link 43 and the third link 44 are rotatably connected can be coupled to the second extension 452. The rotating shafts 453, 454 to which the second link 43 and the third link 44 are rotatably connected can be coupled by penetrating a pair of second extensions 452. For example, the third rotating shaft 453 to which the other end of the second link 43 is coupled and the fifth rotating shaft 454 to which the other end of the third link 44 is coupled can be coupled to the second extension 452. For example, the third rotating shaft 453 and the fifth rotating shaft 454 can be configured as a rivet.

[0147] The second mounting bracket 46 can be provided on an upper portion of the second lower hinge bracket 45. The second mounting bracket 46 can fix the second lower hinge bracket 45 to the upper door 21. For example, the second mounting bracket 46 can be mounted to the second recess 2122 of the upper door 21. The lower end of the second mounting bracket 46 is coupled to the second lower hinge bracket 45, and the upper end thereof is coupled to the second recess 2122 of the upper door 21, thereby mounting the second lower hinge bracket 45 to the upper door 21. For example, the second mounting bracket 46 can be made of a metal material.

[0148] The second mounting bracket 46 can mount the second lower hinge bracket 45 to the upper door 21. The second mounting bracket 46 can have substantially the same structure as the mounting bracket 36 that mounts the second upper hinge bracket 35 of the first hinge 30 to the upper door 21.

[0149] The second mounting bracket 46 can include a first mounting portion 461 mounted on the upper door 21, a second mounting portion 462 mounted on the second lower hinge bracket 45, and a connecting portion 463 connecting the first mounting portion 461 and the second mounting portion 462.

[0150] The first mounting portion 461 can be mounted in the second recess 2122 of the upper door 21. For example, the first mounting portion 461 can be mounted in the second recess 2122 formed in the lower cap trim 212.

[0151] The first mounting portion 461 can include a first fastening hole 461a to which the mounting portion 47 is mounted. The first mounting portion 461 can be fixedly mounted to the second recess 2122 via the mounting portion 47. A plurality of first fastening holes 461a of the first mounting portion 461 can be formed. For example, the first fastening holes 461a can be formed at one end and the other end of the first mounting portion 461, respectively.

[0152] The second recess 2122 can include a recessed fastening hole 2122a which is open in the vertical direction. The mounting portion 47 can be fastened by penetrating the first fastening hole 461a of the first mounting portion 461 and the recessed fastening hole 2122a of the second recess 2122. Accordingly, the first mounting portion 461 can be fixedly mounted to the second recess 2122 of the upper door 21. In other words, through the above-described structure, the first mounting portion 461 can be vertically fixedly mounted to the second recess 2122 of the upper door 21.

[0153] A fixing bracket 48 to which the mounting portion 47 is fastened can be provided on a lower surface of the second recess 2122. The fixing bracket 48 can include a boss portion to which the mounting portion 47 is fastened. For example, the fixing bracket 48 can be made of a metal material. Accordingly, by fastening the mounting portion 47 to the fixing bracket 48, the second mounting bracket 46 can be firmly mounted to the second recess 2122.

[0154] The second mounting portion 462 can be mounted on the second upper extension 452a of the second lower hinge bracket 45. The second mounting portion 462 can be positioned at a lower portion of the second upper extension 452a.

[0155] The third rotation shaft 453 can extend to an upper portion of the second upper extension 452a and be fixed by penetrating the second mounting portion 462. The fifth rotation shaft 454 can extend to the upper portion of the second upper extension 452a and be fixed by penetrating the second mounting portion 462. In other words, the second lower extension 452b and the second mounting portion 462 can be fixed by the third rotation shaft 453 and the fifth rotation shaft 454.

[0156] The second lower hinge bracket 45 is mounted on the second mounting portion 462, and the first mounting portion 461 is mounted on the second recess 2122, so that the second lower hinge bracket 45 can be mounted on the upper door 21 by the second mounting bracket 46.

[0157] The connection portion 463 of the second mounting bracket 46 can connect the first mounting portion 461 and the second mounting portion 462. The connection portion 463 can connect a front end of the first mounting portion 461 and a front end of the second mounting portion 462. The connection portion 463 can be formed in a convex curved shape facing the front. An upper end of the connection portion 463 can be connected to the front end of the first mounting portion 461, and a lower end thereof can be connected to the front end of the second mounting portion 462. The first mounting portion 461 can extend forward from the upper end of the connection portion 463, and the second mounting portion 462 can extend forward from the lower end of the connection portion 463.

[0158] Due to the convex curved shape of the connection portion 463, the load applied to the first mounting portion 461 or the second mounting portion 462 can be distributed. Thus, due to the shape of the connection portion 463, the stability of the coupling between the upper door 21 and the second lower hinge bracket 45 through the second mounting bracket 46 can be improved.

[0159] As described above, the second mounting bracket 46 of the second hinge 40 has substantially the same structure as the mounting bracket 36 included in the first hinge 30, such that the description of the mounting bracket 36 of the first hinge 30 can be equally applied to the components not directly described with respect to the second mounting bracket 46 of the second hinge 40.

[0160] The refrigerator 1 according to one embodiment has an advantage in that the load of the door 20 applied to the first hinge 30 and the second hinge 40 of the multi-link structure is distributed, thereby stably fixing the door 20 to the first hinge 30 and the second hinge 40.

[0161] The refrigerator 1 according to one embodiment, in which the door 20 is mounted on the first hinge 30 and the second hinge 40 of the multi-link structure, has an advantage in that deformation of the structure of the door 20 can be minimized.

[0162] The refrigerator 1 according to one embodiment, in which the door 20 is vertically fastened to the structure of the first hinge 30 and the second hinge 40 of the multi-link structure, can be applied to the door 20 of various structures.
