REFRIGERATOR

BACKGROUND

[0001]The present disclosure relates to a refrigerator.

[0002]In general, a refrigerator is a home appliance that can store food at low temperatures in an internal storage space that is shielded by a door. Specifically, a refrigerator can store stored food in an optimal condition by cooling the interior of the storage space using cold air generated through heat exchange with a refrigerant that circulates a refrigeration cycle.

[0003]Recent refrigerators are becoming larger and more multifunctional in line with changes in eating habits and the trend toward higher quality products, and are being released in various structural forms that take user convenience into consideration.

[0004]For example, recently, refrigerators are being built into walls or are being configured to be disposed in harmony with other furniture or home appliances. At this time, in order to prevent the corners of the refrigerator's rotating door 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 aesthetic problems.

[0005]To solve these problems, a multi-link hinge device has recently been developed that allows the refrigerator door to rotate without interfering with adjacent components. Representatively, Korean Patent No. 10-1497295 discloses a multi-link hinge having a compact structure and a multi-coupling structure, which provides a rotational structure in which the door does not interfere with adjacent components when mounted on a refrigerator door.

[0006]Meanwhile, as refrigerators become larger and more multifunctional, the load on the door is becoming heavier. This has led to a demand for the development of a hinge device that can stably support the load on the door.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0052]Hereinafter, specific embodiments of the present disclosure will be described in detail with reference to the drawings. However, the present disclosure is not limited to the embodiments in which the idea of the present disclosure is presented, and other regressive disclosures or other embodiments included within the scope of the idea of the present disclosure can be easily proposed by adding, changing, deleting, or the like other components.

[0053]Before explanation, the direction is defined. In an embodiment of the present disclosure, the direction in which the front surface of the door as illustrated in FIGS. 1 and 2 faces may be defined as a front direction, the direction toward the cabinet based on the front surface of the door may be defined as a rear direction, the direction toward the floor surface on which the refrigerator is installed may be defined as a lower direction, and the direction away from the floor surface may be defined as an upper direction. In addition, when you want to talk about an undefined direction, you can explain it by defining the direction based on each drawing.

[0054]Although the embodiment of the present disclosure describes a refrigerator in which a refrigerating compartment and a freezing compartment are disposed 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.

[0055]FIG. 1 is a front view illustrating a refrigerator according to one embodiment. FIG. 2 is a perspective view illustrating a refrigerator with a door open according to one embodiment.

[0056]Referring to FIGS. 1 and 2, a refrigerator 1 according to one embodiment can include a cabinet 10 forming a storage space with 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 outer appearance of the refrigerator 1.

[0057]According to one embodiment, a refrigerator 1 can be installed so as to be in harmony with furniture or a wall O of an indoor space. For example, as illustrated in FIG. 1, the refrigerator 1 can be installed in an indoor space such as a kitchen, and can be disposed so as to be in harmony with furniture or a wall O.

[0058]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 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 or material having the same texture as the furniture or the wall O, so that the front surface of the refrigerator 1 can have a greater sense of unity with the adjacent furniture or the wall O.

[0059]Looking at the structure of the refrigerator 1 in detail, the cabinet 10 can form a storage space 11 partitioned vertically. For example, the cabinet 10 can be partitioned vertically by a barrier 14. The cabinet 10 can form an upper storage space 11 located above the barrier 14 and a lower storage space (not illustrated) located below the barrier 14.

[0060]For example, a refrigerator 1 according to one embodiment can be configured as a bottom freeze type. In other words, the upper storage space 11 of the refrigerator 1 can be used as a refrigerating compartment, and the lower storage space can be used as a freezing compartment. Accordingly, the upper storage space 11 can be referred to as a refrigerating compartment, and the lower storage space can be referred to as a freezing chamber.

[0061]The door 20 can include an upper door 21 that opens and closes the upper storage space 11 and a lower door 22 that opens and closes the lower storage space.

[0062]The upper door 21 can be rotatably mounted on the cabinet 10. The upper door 21 can open and close the upper storage space 11 by rotating. The upper door can be connected to the cabinet 10 by a first hinge 30 and a second hinge 40 respectively coupled to the upper end and the lower end of the upper door 21.

[0063]The upper doors 21 can be provided as a pair on the left and right sides. The pair of upper doors 21 can be configured to independently rotate to open and close the upper storage space 11.

[0064]For example, the upper door 21 can include an upper cap decoration 211 forming the upper surface, a lower cap decoration 212 forming the lower surface, a side decoration 213 forming the side surface, a door liner 214 forming the rear surface, and a front panel ‘215’ (FIG. 4) forming the front surface.

[0065]A first hinge 30 can be coupled to the upper end of the upper door 21, and a second hinge 40 can be coupled to the lower end. For example, the first hinge 30 can be coupled to the upper cap decoration 211 of the upper door 21, and the second hinge 40 can be coupled to the lower cap decoration 212 of the upper door 21. The upper door 21 can be rotatably connected to the cabinet 10 by the first hinge 30 and the second hinge 40.

[0066]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 rotate smoothly without interfering with neighboring furniture or walls O during the opening and closing process.

[0067]A refrigerator 1 according to one embodiment can further include a first hinge cover 15 mounted on the upper surface of the cabinet 10. For example, the first hinge cover 15 is provided on the upper surface of the front end of the cabinet 10 and can partially shield the first hinge 30.

[0068]Meanwhile, the lower door 22 can be configured as a drawer-type door that can be pulled in and out. However, the present disclosure is not limited thereto, and the lower door 22 can be rotatably mounted on the cabinet 10 through hinges provided at the upper and lower ends in the same manner as the upper door 21, respectively, thereby opening and closing the lower storage space.

[0069]FIG. 3 and FIG. 4 are partial perspective views illustrating a mounting state of a first hinge of a refrigerator according to one embodiment.

[0070]Referring to FIG. 3 and FIG. 4, the first hinge 30 can be mounted on the upper end of the front surface of the cabinet 10. The first hinge 30 can be mounted at a position adjacent to the side from the upper end of the front surface of the cabinet 10. The first hinge 30 can be connected to the upper end of the rear surface of the upper door 21.

[0071]The upper door 21 can include a hinge mounting part 21a on which a first hinge 30 is mounted. The hinge mounting part 21a can be formed by the upper surface of the upper door 21 being recessed downward. The hinge mounting part 21a can also be viewed as being formed by the rear surface of the upper door 21 being recessed forward. For example, the hinge mounting part 21a can be formed in the upper cap decoration 211. In other words, the hinge mounting part 21a can be formed by the upper cap decoration 211 being partially recessed.

[0072]The upper door 21 can include a bottom part 2111 forming a bottom surface of a hinge mounting part 21a and a first recessed part 2112 formed by being recessed more than the bottom part 2111. For example, the upper cap decoration 211 can include a bottom part 2111 forming a bottom surface of the hinge mounting part 21a and a first recessed part 2112. The bottom part 2111 can be formed around the first recessed part 2112. As will be described later, a first hinge 30 can be mounted on the first recessed part 2112.

[0073]The upper capdecoration 211 can include a capdecoration opening ‘211a’ (FIG. 8) formed in front of the first hinge 30. The capdecoration opening 211a can be shielded by the front panel 215.

[0074]The cabinet 10 can include a first cabinet bracket 12 provided on the upper end of the front surface. A first hinge 30 can be mounted on the first cabinet bracket 12. For example, the first cabinet bracket 12 can be coupled to a first hinge cover 15 via a fastening member 311a.

[0075]The first hinge 30 can have a multi-link hinge structure in which a plurality of links are coupled. The rotational 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. Therefore, the first hinge 30 can be referred to as a multi-link hinge.

[0076]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 that mounts the second upper hinge bracket 35 to the upper door 21, and a plurality of links 32, 33, 34 provided between the first upper hinge bracket 31 and the second upper hinge bracket 35.

[0077]The first upper hinge bracket 31 can be formed in the shape of a metal plate, and the upper and lower surfaces can be bent to form an accommodation space capable of accommodating a number of links to be described later.

[0078]The first upper hinge bracket 31 can include a first base part 311 that is fixed in contact with the cabinet 10, a first extension part 312 formed by extending forward from the upper and lower ends of the first base part 311, and a first side part 313 that extends forward from the side ends of the first base part 311.

[0079]The first base part 311 can be mounted on the front surface of the cabinet 10. The first base part 311 is formed in a plate shape and can be positioned facing the front surface of the cabinet 10. The first base part 311 can be fixed to the front surface of the upper end of the cabinet 10 through a fastening member 311a. For example, the first base part 311 can be fixed to the first cabinet bracket 12 mounted on the upper surface of the cabinet 10 and mounted on the front surface of the cabinet 10.

[0080]The first extension part 312 can be bent perpendicularly to the first base part 311 and can extend forward. The first extension parts 312 can be configured as a pair spaced apart from each other. The first extension parts 312 can extend forward from the upper and lower ends of the first base part 311, respectively.

[0081]A rotational shaft 314, 315 to which the first link 32 and the third link 34 are rotatably connected can be coupled to the first extension part 312. The rotational shaft 314, 315 to which the first link 32 and the third link 34 are rotatably connected can be coupled by penetrating through a pair of the first extension parts 312. In this specification, the rotational shaft can not only mean an imaginary shaft that becomes the center of rotation of a rotating object, but can also refer to a configuration forming the center of rotation.

[0082]The first side part 313 can extend forward from the side end of the first base part 311. The first side part 313 can connect a pair of first extension parts 312. For example, the upper and lower ends of the first side part 313 can be respectively coupled to a pair of first extension parts 312. The first side part 313 can maintain a separation distance between the pair of first extension parts 312. Through the above structure, the first side part 313 can reinforce the structure so that the first upper hinge bracket 31 can support the load of the upper door 21.

[0083]As described above, the first hinge 30 can include a plurality of links 32, 33, 34 provided between the first upper hinge bracket 31 and the second upper hinge bracket 35. Each of these 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.

[0084]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 part of the first link 32 can be axially coupled to the first upper hinge bracket 31 via the first rotation shaft 314, and the other end part can be axially coupled to the second link 33 via the second rotation shaft 321. 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 part of the second link 33 can be axially coupled to the first link 32 via the second rotation shaft 321, and the other end part can be axially coupled to the second upper hinge bracket 35 via the third rotation shaft 353.

[0085]The second link 33 can be provided with a spring (not illustrated) that is tensioned or compressed according to the rotation of the second link 33 and forces the rotation of the second link 33. 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 restored just before the upper door 21 is closed.

[0086]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 part of the third link 34 can be axially coupled to the first link 32 via the fourth rotation shaft 322, and the other end part can be axially coupled to the second upper hinge bracket 35 via the fifth rotation shaft 354.

[0087]Although not illustrated, the first upper hinge bracket 31 and the third link 34 can be connected by a linear damper (not illustrated) whose two ends are axially coupled. In other words, the third link 34 can be connected to the sixth rotational shaft 315 of the first upper hinge bracket 31 via the linear damper (not illustrated). For example, one end part of the linear damper can be rotatably axially coupled to the sixth rotational shaft 315, and the other end part can be coupled to the third link 34. The other end part of the linear damper can be coupled to a position between the one end part and the other end part of the third link 34. The linear damper can reduce the rotation and alleviate impact when the first hinge 30 is folded, that is, when the upper door 21 is closed.

[0088]By the action of the linear damper and the spring, a plurality of links 32, 33, 34 constituting the first hinge 30 are able to rotate while maintaining a set trajectory.

[0089]The second upper hinge bracket 35 can be formed in the shape of a metal plate, and the upper and lower surfaces can be bent to form an accommodation space capable of accommodating a number of links to be described later.

[0090]The second upper hinge bracket 35 can include a second base part 351 facing the rear surface of the upper door 21 and a second extension part 352 formed to extend rearward from the upper and lower ends of the second base part 351.

[0091]The second base part 351 is formed in a plate shape and can be disposed to face the rear surface of the upper door 21. For example, the second base part 351 can be disposed to face the rear surface of the upper door 21 forming the front surface of the hinge mounting part 21a. The second base part 351 can be disposed to face one surface of the upper cap decoration 211 forming the front surface of the hinge mounting part 21a.

[0092]The second extension part 352 can be bent perpendicularly to the second base part 351 and can extend rearward. The second extension part 352 can be configured as a pair spaced apart from each other. The second extension part 352 can include a second upper extension part 352a extending rearward from the upper end of the second base part 351 and a second lower extension part 352b extending rearward from the lower end.

[0093]A rotational shaft 353, 354 to which the second link 33 and the third link 34 are rotatably connected can be coupled to the second extension part 352. The rotational 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 second extension parts 352. For example, a third rotational shaft 353 to which the other end part of the second link 33 is coupled and a fifth rotational shaft 354 to which the other end part of the third link 34 is coupled can be coupled to the second extension part 352. For example, the third rotational shaft 353 and the fifth rotational shaft 354 can be configured as rivets.

[0094]A first mounting bracket 36 can be disposed at the lower part of the second upper hinge bracket 35. The first mounting bracket 36 can secure the second upper hinge bracket 35 to the upper door 21. For example, the first mounting bracket 36 can be mounted to the first recessed part 2112 of the upper door 21. The upper end of the first mounting bracket 36 is coupled to the second upper hinge bracket 35, and the lower end thereof is coupled to the first recessed part 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.

[0095]First, the detailed structure of the first mounting bracket 36 will be described with reference to FIGS. 5 and 6.

[0096]FIG. 5 is a perspective view illustrating a first mounting bracket according to one embodiment. FIG. 6 is a plan view illustrating a first mounting bracket according to one embodiment.

[0097]Referring to FIGS. 5 and 6, a detailed structure of the first mounting bracket 36 will be described. The first mounting bracket 36 can include a first mounting part 361 mounted on the upper door 21, a second mounting part 362 mounted on the second upper hinge bracket 35, and a connection part 363 connecting the first mounting part 361 and the second mounting part 362.

[0098]The first mounting part 361 can have a square plate shape extending in one direction. For example, the first mounting part 361 can have a square plate shape having a first width w1 in the longitudinal direction extending therein and a second width w2 smaller than the first width w1 in the width direction intersecting the longitudinal direction.

[0099]The first mounting part 361 can include a first fastening hole 361a to which a fastening member 37 is fastened. A plurality of first fastening holes 361a of the first mounting part 361 can be formed. For example, a pair of first fastening holes 361a can be formed and can be formed at one end part and the other end part of the first mounting part 361, respectively. In addition, the first fastening holes 361a can be disposed so as not to overlap with the second mounting part 362.

[0100]Meanwhile, the first mounting part 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 rotational shaft 353 and the fifth rotational 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 provided to place a jig required for riveting the third rotational shaft 353 and the fifth rotational shaft 354.

[0101]The second mounting part 362 can be formed to be spaced apart from the first mounting part 361. The second mounting part 362 can have a plate shape extending in one direction. As will be described later, the second mounting part 362 can be mounted on the second lower extension part 352b of the second upper hinge bracket 35.

[0102]The second mounting part 362 can have a shape corresponding to the second lower extension part 352b of the second upper hinge bracket 35. For example, the end shape of the second mounting part 362 can have a shape corresponding to the second lower extension part 352b of the second upper hinge bracket 35. Through this, the second mounting part 362 can stably support the second upper hinge bracket 35.

[0103]The second mounting part 362 can have a third width w3 in the extending longitudinal direction and a fourth width w4 smaller than the third width w3 in the width direction intersecting the longitudinal direction.

[0104]Meanwhile, the third width w3, which is the longitudinal width of the second mounting part 362, can be smaller than the first width w1, which is the longitudinal width of the first mounting part 361. In addition, the fourth width w4, which is the width in the width direction of the second mounting part 362, can be smaller than the second width w2, which is the width in the width direction of the first mounting part 361. The area of one side of the second mounting part 362 can be smaller than the area of one side of the first mounting part 361. In addition, the second mounting part 362 can be located inside the first mounting part 361 in the plan view. In other words, the edge of the second mounting part 362 in the plan view can be located inside the edge of the first mounting part 361.

[0105]Through the above structure, the second mounting part 362 can be configured to stably support the second upper hinge bracket 35 while not interfering with the front end of the first extension part 312 of the first upper hinge bracket 31 during the opening and closing process of the upper door 21.

[0106]The second mounting part 362 can include a plurality of fastening holes 362a, 362b. For example, the second mounting part 362 can include a second fastening hole 362a through which the third rotation shaft 353 passes and a third fastening hole 362b through which the fifth rotation shaft 354 passes. The second fastening hole 362a and the third fastening hole 362b can be formed between a pair of first fastening holes 361a.

[0107]The connection part 363 of the first mounting bracket 36 can connect the first mounting part 361 and the second mounting part 362. The connection part 363 can connect one end part of the first mounting part 361 and one end part of the second mounting part 362. The connection part 363 can be formed in a convex curved shape facing forward. The lower end of the connection part 363 can be connected to the one end part of the first mounting part 361, and the upper end thereof can be connected to the one end part of the second mounting part 362. The first mounting part 361 can extend from the lower end to the other side of the connection part 363, and the second mounting part 362 can extend from the upper end to the other side of the connection part 363.

[0108]Due to the convexly curved shape of the connection part 363, the load applied to the first mounting part 361 or the second mounting part 362 can be distributed. Accordingly, due to the shape of the connection part 363, the 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.

[0109]The first mounting bracket 36 can further include a bracket support part 364 formed at the upper end of the connection part 363. The bracket support part 364 can be positioned at one side of the second mounting part 362. The bracket support part 364 can extend upward from the upper end of the connection part 363.

[0110]Hereinafter, the coupling structure between the first hinge 30 and the upper door 21 will be described in detail with reference to FIGS. 7 to 10.

[0111]FIG. 7 is an exploded perspective view illustrating a coupling structure of a first hinge and an upper door in a refrigerator according to one embodiment. FIG. 8 is a cross-sectional view taken along line 8-8 of FIG. 4. FIG. 9 is a cross-sectional view taken along line 9-9 of FIG. 4. FIG. 10 is a cross-sectional view taken along line 10-10 of FIG. 4.

[0112]Referring to FIGS. 7 to 10, the first mounting part 361 of the first mounting bracket 36 can be mounted in the first recessed part 2112 of the upper door 21. For example, the first mounting part 361 can be mounted in the first recessed part 2112 formed in the upper cap decoration 211. The first mounting part 361 can be fixedly mounted in the first recessed part 2112 through a fastening member 37 inserted into the first fastening hole 361a.

[0113]The first recessed part 2112 can include a recessed fastening hole 2112a that is opened in the vertical direction. The fastening member 37 can be fastened by penetrating the first fastening hole 361a of the first mounting part 361 and the recessed fastening hole 2112a of the first recessed part 2112. Accordingly, the first mounting part 361 can be fixedly mounted to the first recessed part 2112 of the upper door 21. In other words, through the above structure, the first mounting part 361 can be fixedly mounted vertically to the first recessed part 2112 of the upper door 21.

[0114]A fixed bracket 38 to which a fastening member 37 is fastened can be disposed on the lower surface of the first recessed part 2112. The fixed bracket 38 can be disposed on the opposite side of the first mounting bracket 36 with the first recessed part 2112 therebetween. The fixed bracket 38 and the first mounting bracket 36 can be fastened to each other through the fastening member 37. The fixed bracket 38 can include a boss part to which the fastening member 37 is fastened. For example, the fixed bracket 38 can be made of a metal material. Therefore, by fastening the fastening member 37 to the fixed bracket 38, the first mounting bracket 36 can be firmly mounted to the first recessed part 2112.

[0115]The second mounting part 362 can be mounted on the second lower extension part 352b of the second upper hinge bracket 35. The second mounting part 362 can be positioned at the lower part of the second lower extension part 352b.

[0116]The third rotation shaft 353 can be extended to the lower part of the second lower extension part 352b and fixed by passing through the second fastening hole 362a. The fifth rotation shaft 354 can be extended to the lower part of the second lower extension part 352b and fixed by passing through the third fastening hole 362b. In other words, the second lower extension part 352b and the second mounting part 362 can be fixed by the third rotation shaft 353 and the fifth rotation shaft 354.

[0117]The second upper hinge bracket 35 is mounted on the second mounting part 362, and the first mounting part 361 is mounted on the first recessed part 2112, so that the second upper hinge bracket 35 can be mounted on the upper door 21 through the first mounting bracket 36.

[0118]Meanwhile, the bracket support part 364 can support the rear side of the second base part 351 of the second upper hinge bracket 35. Through the above structure, when the upper door 21 rotates, the bracket support part 364 of the first mounting bracket 36 presses the second base part 351, so that the stress applied to the third rotation shaft 353 and the fifth rotation shaft 354 can be dispersed.

[0119]Hereinafter, the mounting structure of the second hinge 40 will be described with reference to FIGS. 11 to 14.

[0120]FIGS. 11 to 13 are partial perspective views illustrating a mounting state of a second hinge of a refrigerator according to one embodiment. FIG. 14 is a cross-sectional view taken along line 14-14 of FIG. 12.

[0121]Referring to FIGS. 11 to 14, the second hinge 40 can be mounted on the front surface of the barrier 14 of the cabinet 10. The second hinge 40 can be connected to the lower end of the rear surface of the upper door 21.

[0122]The upper door 21 can include a lower part 2121 forming a lower surface and a second recessed part 2122 formed by being recessed upward from the lower part 2121. For example, the lower cap decoration 212 can include a lower part 2121 and a second recessed part 2122. The lower part 2121 can be formed around the second recessed part 2122. As will be described later, a second hinge 40 can be mounted on the second recessed part 2122.

[0123]The cabinet 10 can include a second cabinet bracket 16 provided on the upper end of the front surface. The second cabinet bracket 16 can be equipped with a second hinge 40.

[0124]The second hinge 40 can have a multi-link hinge structure in which a plurality of links are coupled. The 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. Therefore, the second hinge 40 can be referred to as a multi-link hinge.

[0125]The second hinge 40 can include a first lower hinge bracket 41 mounted on the barrier 14, a second lower hinge bracket 45 positioned at the lower part of the upper door 21, a second mounting bracket 46 that mounts the second lower hinge bracket 45 to the lower surface of the upper door 21, and a plurality of links 42, 43, 44 provided between the first lower hinge bracket 41 and the second lower hinge bracket 45.

[0126]The first lower hinge bracket 41 can be formed in the shape of a metal plate, and the upper and lower surfaces can be bent to form an accommodation space capable of accommodating a number of links to be described later.

[0127]The first lower hinge bracket 41 can include a first base part 411 that is fixed in contact with the cabinet 10, a first extension part 412 that is formed by extending forward from the upper and lower ends of the first base part 411, and a first side part 413 that extends forward from the side end of the first base part 411.

[0128]The first base part 411 can be mounted on the front surface of the cabinet 10. The first base part 411 is formed in a plate shape and can be positioned facing the front surface of the barrier 14. The first base part 411 can be fixed to the front surface of the barrier 14 through a fastening member 411a. For example, the first base part 411 can be fixed to a second cabinet bracket 16 mounted on the barrier 14 and mounted on the front surface of the cabinet 10.

[0129]The first extension part 412 can be bent perpendicularly to the first base part 411 and can extend forward. The first extension parts 412 can be configured as a pair spaced apart from each other. The first extension parts 412 can extend forward from the upper and lower ends of the first base part 411, respectively.

[0130]A rotational shaft 414, 415 to which the first link 42 and the third link 44 are rotatably connected can be coupled to the first extension part 412. The rotational shaft 414, 415 to which the first link 42 and the third link 44 are rotatably connected can be coupled by penetrating through a pair of the first extension parts 412. In this specification, the rotational shaft can not only mean an imaginary axis that becomes the center of rotation of a rotating object, but can also refer to a configuration forming the center of rotation.

[0131]The first side part 413 can extend forward from the side end of the first base part 411. The first side part 413 can connect a pair of first extension parts 412. For example, the upper and lower ends of the first side part 413 can be respectively coupled to a pair of first extension parts 412. The first side part 413 can maintain a separation distance between the pair of first extension parts 412. Through the above structure, the first side part 413 can reinforce the structure so that the first lower hinge bracket 41 can support the load of the upper door 21.

[0132]As described above, the second hinge 40 can include a plurality of links 42, 43, 44 provided between the first lower hinge bracket 41 and the second lower hinge bracket 45. Each of these 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 folding or unfolding.

[0133]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 part of the first link 42 can be axially coupled to the first lower hinge bracket 41 via the first rotation shaft 414, and the other end thereof can be axially coupled to the second link 43 via the second rotation shaft 421.

[0134]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 part of the second link 43 can be axially coupled to the first link 42 via the second rotation shaft 421, and the other end thereof can be axially coupled to the second lower hinge bracket 45 via the third rotation shaft 453.

[0135]The second link 43 can be provided with a spring (not illustrated) that is tensioned or compressed according to the rotation of the second link 43 and forces the rotation of the second link 43. 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 the process of closing the upper door 21 and restored just before the upper door 21 is closed.

[0136]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 part of the third link 44 can be axially coupled to the first link 42 via the fourth rotation shaft 422, and the other end thereof can be axially coupled to the second lower hinge bracket 45 via the fifth rotation shaft 454.

[0137]Although not illustrated, the first lower hinge bracket 41 and the third link 44 can be connected by a linear damper (not illustrated) whose two ends are axially coupled. In other words, the third link 44 can be connected to the sixth rotational shaft 415 of the first lower hinge bracket 41 via the linear damper (not illustrated). For example, one end part of the linear damper can be rotatably axially coupled to the sixth rotational shaft 415, and the other end part thereof can be coupled to the third link 44. The other end part of the linear damper can be coupled to a position between the one end part and the other end part of the third link 44. The linear damper can reduce the rotation and alleviate impact when the second hinge 40 folds, that is, when the upper door 21 closes.

[0138]By the action of the linear damper and the spring, a plurality of links 42, 43, 44 constituting the second hinge 40 are able to rotate while maintaining the set trajectory.

[0139]The second lower hinge bracket 45 can be formed in the shape of a metal plate, and the upper and lower surfaces can be bent to form an accommodation space capable of accommodating a number of links to be described later.

[0140]The second lower hinge bracket 45 can include a second base part 451 facing the rear surface of the upper door 21 and a second extension part 452 formed to extend forward from the upper and lower ends of the second base part 451.

[0141]Meanwhile, the upper door 21 can further include a second hinge cover 216 that extends downward from the lower cap decoration 212. The second hinge cover 216 can cover the second hinge 40 from the front. Through this, 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 decoration 212. The second hinge cover 216 can be positioned in front of the second lower hinge bracket 45.

[0142]The second base part 451 is formed in a plate shape and can be positioned at the lower part of the lower cap decoration 212. For example, the second base part 451 can be positioned to face the rear surface of the second hinge cover 216.

[0143]The second extension part 452 can be bent perpendicularly to the second base part 451 and can extend rearward. The second extension part 452 can be configured as a pair spaced apart from each other. The second extension part 452 can include a second upper extension part 452a extending rearward from the upper end of the second base part 451 and a second lower extension part 452b extending rearward from the lower end.

[0144]A rotational shaft 453, 454 to which the second link 43 and the third link 44 are rotatably connected can be coupled to the second extension part 452. The rotational 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 extension parts 452. For example, a third rotational shaft 453 to which the other end part of the second link 43 is coupled and a fifth rotational shaft 454 to which the other end part of the third link 44 is coupled can be coupled to the second extension part 452. For example, the third rotational shaft 453 and the fifth rotational shaft 454 can be configured as rivets.

[0145]A second mounting bracket 46 can be disposed on the upper part of the second lower hinge bracket 45. The second mounting bracket 46 can secure the second lower hinge bracket 45 to the upper door 21. For example, the second mounting bracket 46 can be mounted to the second recessed part 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 recessed part 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.

[0146]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 hinge bracket 35 of the first hinge 30 to the upper door 21.

[0147]The second mounting bracket 46 can include a first mounting part 461 mounted on the upper door 21, a second mounting part 462 mounted on the second lower hinge bracket 45, and a connection part 463 connecting the first mounting part 461 and the second mounting part 462.

[0148]The first mounting part 461 can be mounted in the second recessed part 2122 of the upper door 21. For example, the first mounting part 461 can be mounted in the second recessed part 2122 formed in the lower cap decoration 212.

[0149]The first mounting part 461 can include a first fastening hole 461a to which a mounting part 47 is mounted. The first mounting part 461 can be fixedly mounted to the second recessed part 2122 via the mounting part 47. A plurality of first fastening holes 461a of the first mounting part 461 may be formed. For example, the first fastening holes 461a can be formed at one end part and the other end part of the first mounting part 461, respectively.

[0150]The second recessed part 2122 can include a recessed fastening hole 2122a that is opened in the vertical direction. The fastening member 47 can be fastened by penetrating the first fastening hole 461a of the first mounting part 461 and the recessed fastening hole 2122a of the second recessed part 2122. Accordingly, the first mounting part 461 can be fixedly mounted to the second recessed part 2122 of the upper door 21. In other words, through the above structure, the first mounting part 461 can be fixedly mounted vertically to the second recessed part 2122 of the upper door 21.

[0151]A fixed bracket 48 to which a fastening member 47 is fastened can be disposed on the lower surface of the second recessed part 2122. The fixed bracket 48 can include a boss part to which the fastening member 47 is fastened. For example, the fixed bracket 48 can be made of a metal material. Accordingly, by fastening the fastening member 47 to the fixed bracket 48, the second mounting bracket 46 can be firmly mounted to the second recessed part 2122.

[0152]The second mounting part 462 can be mounted on the second upper extension part 452a of the second lower hinge bracket 45. The second mounting part 462 can be positioned at the lower part of the second upper extension part 452a.

[0153]The third rotation shaft 453 can be extended to the upper part of the second upper extension part 452a and fixed by penetrating the second mounting part 462. The fifth rotation shaft 454 can be extended to the upper part of the second upper extension part 452a and fixed by penetrating the second mounting part 462. In other words, the second lower extension part 452b and the second mounting part 462 can be fixed by the third rotation shaft 453 and the fifth rotation shaft 454.

[0154]The second lower hinge bracket 45 is mounted on the second mounting part 462, and the first mounting part 461 is mounted on the second recessed part 2122, so that the second lower hinge bracket 45 can be mounted on the upper door 21 through the second mounting bracket 46.

[0155]The connection part 463 of the second mounting bracket 46 can connect the first mounting part 461 and the second mounting part 462. The connection part 463 can connect the front end of the first mounting part 461 and the front end of the second mounting part 462. The connection part 463 can be formed in a convex curved shape facing forward. The upper end of the connection part 463 can be connected to the front end of the first mounting part 461, and the lower end thereof can be connected to the front end of the second mounting part 462. The first mounting part 461 can extend forward from the upper end of the connection part 463, and the second mounting part 462 can extend forward from the lower end of the connection part 463.

[0156]Due to the convexly curved shape of the connection part 463, the load applied to the first mounting part 461 or the second mounting part 462 can be distributed. Accordingly, due to the shape of the connection part 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.

[0157]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, so that the description of the mounting bracket 36 of the first hinge 30 can be applied equally to parts not directly described with respect to the second mounting bracket 46 of the second hinge 40.

[0158]According to a refrigerator 1 according to one embodiment, there is 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.

[0159]According to a refrigerator 1 according to one embodiment, in a structure in which a door 20 is mounted on a first hinge 30 and a second hinge 40 of a multi-link structure, there is an advantage in that structural deformation of the door 20 can be minimized.

[0160]According to a refrigerator 1 according to one embodiment, the first hinge 30 and the second hinge 40 of the multi-link structure can be applied to doors 20 of various structures through a structure in which the first hinge 30 and the second hinge 40 of the multi-link structure are vertically fastened to the door 20.

[0161]Meanwhile, the present disclosure can have various other embodiments in addition to the above-described embodiments. Hereinafter, other embodiments of the present disclosure will be described with reference to the drawings.
