[0001] This specification relates to a refrigerator.

[0002] In general, a refrigerator is a home appliance that allows food to be stored at a low temperature in an internal storage space that is shielded by a refrigerator door. It is configured to 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 circulating in a refrigeration cycle.

[0003] The above refrigerator can be placed independently in a kitchen or living room, or stored inside a kitchen cabinet.

[0004] The above refrigerator may include a cabinet forming a storage space and a door connected to the cabinet to open and close the storage space.

[0005] For example, if the above refrigerator is installed inside a cabinet, there is a risk that the door may hit the cabinet during the opening process, which may limit the opening angle of the door.

[0006] Recently, a hinge structure has been developed to prevent the door from interfering with surrounding structures such as furniture during the door opening process.

[0007] Prior literature related to this includes International Publication WO2019 / 007278A1.

[0008] One embodiment provides a refrigerator in which interference with surrounding structures is prevented during the door opening process as the opening angle of the door increases.

FIG. 6 is a drawing showing a part of a side surface of the refrigerator according to the first embodiment.

[0054] Referring to FIGS. 1 to 6, the refrigerator (1) according to the present embodiment can be installed independently in a kitchen or installed in a form accommodated in a furniture cabinet or wall inside an indoor space (hereinafter collectively referred to as a “furniture cabinet”).

[0055] When the refrigerator (1) is installed in the cabinet, the refrigerator (1) may be installed alone or arranged left and right together with other refrigerators.

[0056] The above refrigerator (1) may include a cabinet (10) having a storage space. The above refrigerator (1) may further include a door (20) for opening and closing the storage space.

[0057] The above storage space is not limited, but may be divided into a first space (11) on the upper side and a second space (12) on the lower side. The door (20) may also include a first door (21) that opens and closes the first space (11) and a second door (22) that opens and closes the second space (12).

[0058] The first space may be a refrigerator, and the second space may be a freezer, or vice versa. Alternatively, the storage space may include a first space and a second space divided into left and right sides. Alternatively, the storage space may be a single space, with a single door opening and closing the storage space.

[0059] At least one of the first door (21) and the second door (22) may be a rotary door. Alternatively, a single door (20) may be a rotary door. Hereinafter, the rotary door (20), as an example, the first door (21), will be described.

[0060] In the present embodiment, the first door (21) can be rotatably connected to the cabinet (10) by a first hinge mechanism (30) and a second hinge mechanism (40).

[0061] The first door (21) may include a pair of doors arranged left and right. The exteriors of the pair of doors may be formed in a symmetrical shape. In addition, each of the pair of doors may be rotatably connected to the cabinet (10) by a first hinge mechanism (30) and a second hinge mechanism (40).

[0062] The first hinge mechanism (30) may be connected to the upper side of the first door (21). The second hinge mechanism (40) may be connected to the lower side of the first door (21). The first hinge mechanism (30) may be referred to as an upper hinge mechanism. The second hinge mechanism (40) may be referred to as a lower hinge mechanism.

[0063] The first hinge mechanism (30) may include a first hinge body (310). The first hinge body (310) may be coupled to the upper surface or front surface of the cabinet (10). A portion of the first hinge body (310) may overlap the upper side of the first door (21) in the vertical direction.

[0064] The first door (21) may include a hinge mounting portion (210). The hinge mounting portion (210) may be formed by the rear surface of the first door (21) being recessed forward, or by one side being recessed toward the other side. A portion of the first hinge body (310) may be positioned in the hinge mounting portion (211).

[0065] The second hinge mechanism (40) may include a second hinge body (410). The second hinge body (410) may be coupled to the front or bottom of the cabinet (10). A portion of the second hinge body (410) may overlap the lower side of the first door (21) in a vertical direction. The second hinge body (410) may support the load of the first door (21).

[0066] When a refrigerator (1) is installed in a cabinet or a kitchen, the opening angle of the first door (21) needs to be increased without interfering with the cabinet or surrounding structures during the opening process of the first door (21).

[0067] In the present embodiment, the opening angle of the first door (21) can be increased without interfering with the furniture or surrounding structures by the first hinge mechanism (30) and the second hinge mechanism (40). For example, the first hinge mechanism (30) and the second hinge mechanism (40) can cause the rotation center of the first door (21) to move in at least a portion of the entire opening range of the first door (21).

[0068] Hereinafter, the first hinge mechanism (30) and the second hinge mechanism (40) will be described in detail.

[0069] The above first hinge mechanism (30) may further include a first pin unit (330).

[0070] The first pin unit (320) may include a first pin (321) and a second pin (322). The first pin (321) and the second pin (322) may be spaced apart from each other in the first hinge body (310). The first pin (321) and the second pin (322) may be formed integrally with or coupled to the first hinge body (310).

[0071] The first pin (321) and the second pin (322) may be formed of a material having high wear resistance and strength to ensure the opening and closing of the first door (21) without being damaged even when the first door (21) is repeatedly opened and closed. For example, the first pin (321) and the second pin (322) may be formed of a metal material.

[0072] The first pin (321) and the second pin (322) may, for example, extend from the first hinge body (310) toward the first door (21). The first pin (321) and the second pin (322) may extend downward from the first hinge body (310).

[0073] The first door (21) may include a first pin slot (222) in which the first pin unit (320) is accommodated. The first pin (321) and the second pin (322) may be accommodated in the first pin slot (222). The first pin slot (222) may be located at the bottom (211) of the hinge mounting portion (210).

[0074] The first pin slot (222) may be formed by one side of the first door (21) being sunken downward. Alternatively, the first door (21) may include a guide member (220) forming the first pin slot (222). The guide member (220) is coupled to the first door (21), and the first pin slot (222) may be exposed toward the hinge mounting portion (210), for example.

[0075] The above guide member (220) may be formed of a non-metallic material, and may be, for example, an injection-molded product. For example, the guide member (220) may be formed of an engineering plastic material having wear resistance and lubricity. Accordingly, the guide member (220) may be formed of a non-metallic material and may be formed of an engineering plastic material having wear resistance and lubricity. Accordingly, the guide member (220) may be formed of a non-metallic material and may be formed of an engineering plastic material having wear resistance and lubricity. Accordingly, the guide member (220) may be formed of a non-metallic material and may be formed of an engineering plastic material having wear resistance and lubricity. Accordingly, the guide member (220) may be formed of a non-metallic material and may be formed of an engineering plastic material having wear resistance and lubricity, ...

[0076] The first hinge body (310) may be spaced apart from the guide member (220). Some of the first pin (321) and the second pin (322) may be accommodated in the first pin slot (222), and other parts may be positioned outside the first pin slot (222).

[0077] By this structure, friction between the first hinge body (310) and the guide member (220) can be prevented.

[0078] The first pin slot (222) may include a curve. The curvature of the first pin slot (222) may be stepwise or continuously variable. When the curvature of the first pin slot (222) is stepwise variable, the first pin slot (222) may be divided into a plurality of sections. The curvatures of two adjacent sections among the plurality of sections may be different from each other.

[0079] The first door (21) can be opened while the first pin (321) and the second pin (322) are accommodated in the first pin slot (222). The rotation center of the first door (21) can be moved depending on the shape of the first pin slot (222).

[0080] Depending on the shape of the first pin slot (222), the rotation center can move continuously or stepwise.

[0081] The above second hinge mechanism (40) may further include a second pin unit (420).

[0082] The second hinge body (410) may include, for example, a coupling portion (411) coupled to the cabinet (10) and an extension portion (412) extending from the coupling portion (411).

[0083] The above-mentioned connecting portion (411) may be connected to the front of the cabinet (10), for example. One or more connecting holes (411a) into which a connecting member is connected may be formed in the connecting portion (411).

[0084] The above second pin unit (420) can be provided in the extension part (412).

[0085] The second pin unit (420) may include a first hinge pin (421) and a second hinge pin (422).

[0086] The first hinge pin (421) and the second hinge pin (422) may be formed integrally with the extension (412) or may be coupled to the extension (412).

[0087] When the first hinge pin (421) and the second hinge pin (422) are coupled to the extension (412), for example, a portion of each of the first hinge pin (421) and the second hinge pin (422) can be pressed into a hole formed in the extension (412).

[0088] The first hinge pin (421) may include a flange (423) that contacts the extension (412) and a first pin (421a) extending from the flange (423).

[0089] The second hinge pin (422) may include a flange (423) that contacts the extension (412) and a second pin (422a) that extends from the flange (423). The flange of the first hinge pin may be referred to as a first flange, and the flange of the second hinge pin may be referred to as a second flange.

[0090] The first pin (421a) of the second hinge mechanism (40) can be aligned vertically with the first pin (321) of the first hinge mechanism (30). The second pin (422a) of the second hinge mechanism (40) can be aligned vertically with the second pin (322) of the first hinge mechanism (30).

[0091] The diameter of the flange (423) is larger than the diameter of the first pin (421a) and the diameter of the second pin (422a). Therefore, the downward movement of each hinge pin (421, 422) can be restricted by the flange (423).

[0092] The first pin (421a) and the second pin (422a) can be inserted into the lower side of the first door (21) to enable rotation of the first door (21).

[0093] Each of the first and second hinge pins (421, 422) may further include a third pin (424) for rotation of the second door (22). The third pin (424) may extend downward from the flange (423). Of course, it is also possible for the third pin (424) to be omitted and for the second door (22) to be configured to be rotatable by a hinge pin separate from each of the hinge pins (421, 422).

[0094] The first door (21) may further include a second pin slot (232) in which the second pin unit (420) is accommodated. The second pin slot (232) may be provided on the lower side of the first door (21). The second pin slot (232) may be formed as the lower surface of the first door (21) is sunken upward. Alternatively, the first door (21) may include a guide member (230) forming the second pin slot (232). The guide member (230) may be coupled to the lower side of the first door (21). Since the second pin slot (232) may be formed in the same shape as the first pin slot (222), a detailed description thereof will be omitted.

[0095] The above guide member (230) may be formed of a non-metallic material, and may be, for example, an injection-molded material. For example, the guide member (230) may be formed of an engineering plastic material having wear resistance and lubricity. Accordingly, the guide member (230) may be formed of a non-metallic material having wear resistance and lubricity, and may be formed of a non-metallic ...

[0096] The above first and second hinge pins (421, 422) may be formed of a metal material to ensure the opening and closing of the first door (21) without being damaged even when the first door (21) is repeatedly opened and closed.

[0097] In a state where the first door (21) and the second hinge mechanism (40) are coupled, the load of the first door (21) is applied to the second hinge mechanism (40). A part of the guide member (230) may protrude downward from the first door (21), and when the guide member (230) comes into contact with the flange (423) of each hinge pin (421, 422), the load may be applied to the flange (423).

[0098] The above flange (423) is made of a metal material, while the guide member (230) is formed of a non-metallic material (e.g., a plastic material). If the flange (423) is in direct contact with the guide member (230) and rubs against it, the guide member (230) may wear out.

[0099] In particular, since the area of ​​the flange (423) is considerably small compared to the area of ​​the extension (412), the possibility of wear of the guide member (230) is high as the load is concentrated toward the flange (423). If the guide member (230) wears out, there is a concern that the opening and closing of the first door (21) may not be smooth.

[0100] Accordingly, in the present embodiment, a plate (430) may be further included to prevent direct friction between the flange (423) and the guide member (230) and to increase the contact area with the guide member (230) to minimize wear of the guide member (230).

[0101] The above plate (430) can be positioned between the flange (423) and the guide member (230). The plate (430) can be coupled with the second pin unit (420).

[0102] For example, the plate (430) may be mounted on the flange (423) with the first pin (421) and the second pin (422) penetrating the plate (430). The specific shape of the flange (423) will be described later with reference to the drawings.

[0103] Meanwhile, the refrigerator may further include the stopping member (250). The stopping member (250) may limit the rotation of the first door (21) when the first door (21) is opened to the maximum opening angle.

[0104] The above stopping member (250) may be fastened to the lower side of the first door (21), for example. The stopping member (250) may include a body (251) and a stopper (252) bent from the body (251).

[0105] The above body (251) can be fastened to the lower side of the first door (21). An opening (253) through which the guide member (230) passes can be formed in the body (251).

[0106] The above extension (412) may include a contact portion (416) with which the stopper (252) can come into contact. If the stopper (252) comes into contact with the contact portion (416) during the opening process of the first door (21), the opening of the first door (21) may be restricted.

[0107] The first door (21) may further include a shielding member (219) that covers the stopper (252). The shielding member (219) may reduce the exposure of the stopper (252) to the front of the first door (21).

[0108] The above refrigerator may further include a closing member (260). The closing member (260) may assist in closing the first door (21).

[0109] The closing member (260) is provided on the lower side of the first door (21), and when the first door (21) is rotated below a set angle, it comes into contact with the extension part (412) and is elastically deformed, thereby slowing down the closing speed of the first door (21). When the first door (21) is further rotated below the set angle, the end of the closing member (260) is elastically restored while being received in the receiving groove (414) formed in the extension part (412), thereby providing elastic force so that the first door (21) can be completely closed. Of course, the closing member (260) may have various structures that enable the first door (21) to be closed below the set angle.

[0110] The closing member (260) can be fastened to the lower side of the first door (21) by a fastening member. The fastening member fastened to the closing member (260) can be fastened to the first door (21) by penetrating the body (251) of the stopping member (250).

[0111] Fig. 7 (a) is a perspective view of a plate according to the first embodiment, and Fig. 7 (b) is a plan view of a plate according to the first embodiment.

[0112] Fig. 8 (a) is a drawing showing a side view of a plate according to the first embodiment, and Fig. 8 (b) is a drawing showing a modified example of the plate of Fig. 8 (a). Fig. 9 is a cross-sectional view showing a state in which the plate according to the first embodiment is coupled with a second pin unit.

[0113] Referring to FIGS. 7 to 9, the plate (430) of the present embodiment may be formed of a different material from the guide member (230). The plate (430) may be formed of a metal material. For example, the plate (430) may be formed of a stainless steel material.

[0114] When the above plate (430) is formed of a metal material, deformation or damage of the plate (430) can be prevented even if the load of the first door (21) is applied to the plate (430).

[0115] The first pin (421a) and the second pin (422a) may penetrate the plate (430). The plate (430) may include a first hole (431) through which the first pin (421a) penetrates, and a second hole (432) through which the second pin (422a) penetrates. The first hole (431) and the second hole (432) may be spaced apart from each other.

[0116] The first hole (431) may be formed in a circular shape, an elliptical shape, or a shape similar to an ellipse. The second hole (432) may be formed in a circular shape, an elliptical shape, or a shape similar to an ellipse.

[0117] When the first hole (431) and the second hole (432) are formed in a circular shape, the diameter of each of the first hole (431) and the second hole (432) may be larger than the diameter of each of the first pin (321) and the second pin (322).

[0118] In this case, there is an advantage in that assembly of the plate (430) is possible despite the manufacturing tolerance of the plate (430) and the first and second pins (421a, 422a) and the assembly tolerance of the plate (430) and the first and second pins (421a, 422a).

[0119] When each of the first hole (431) and the second hole (432) is formed in an oval shape, the first size (D1) in a direction parallel to the arrangement direction of the first hole (431) and the second hole (432) may be larger than the second size (D2) in a direction intersecting the arrangement direction. In addition, the second size (D2) may be equal to or larger than the diameter of each of the first pin (421a) and the second pin (422a).

[0120] In the above plate (430), the size in the arrangement direction of the first hole (431) and the second hole (432) may be referred to as the length (L), and the size in the direction intersecting the arrangement direction may be referred to as the width (W).

[0121] In order to increase the contact area between the plate (430) and the guide member (230), the plate (430) may be formed in an elliptical shape or a shape similar to an ellipse.

[0122] The length (L) of the above plate (430) may be greater than the width (W) of the above plate (430).

[0123] Based on the length of the above plate (430), the width (W) of the middle portion of the plate (430) may be greater than the width of the ends on both sides.

[0124] The width (W) of a portion of the plate (430) may be at least twice the second size (D2). The width (W) of a portion of the plate (430) may be greater than the distance between the center of the first hole (431) and the center of the second hole (432).

[0125] The above plate (430) may include a portion whose width (W) is greater than the diameter of the flange (423). When the plate (430) is seated on the flange (423), the width of the portion of the plate (430) where the first hole (431) is formed and the width of the portion of the plate (430) where the second hole (432) is formed may be greater than the diameter of the flange (423).

[0126] The above plate (430) may include a first surface (430a) and a second surface (430b) facing each other. One surface of the first surface (430a) and the second surface (430b) may be in contact with the guide member (230), and the other surface may be in contact with the flange (423).

[0127] The above plate (430) may further include a peripheral surface (434) (or side surface). The length of the peripheral surface (434) in the arrangement direction of the first surface (430a) and the second surface (430b) may be shorter than the distance between the first surface (430a) and the second surface (430b).

[0128] The first surface (430a) can be connected to one end of the peripheral surface (434) by a first connecting surface (435a). The second surface (430b) can be connected to the other end of the peripheral surface (434) by a second connecting surface (435b).

[0129] The above first connecting surface (435a) may be an inclined surface or a round surface. The above second connecting surface (435b) may be an inclined surface or a round surface.

[0130] The first connecting surface (435a) may be arranged to surround the first surface (430a), and the second connecting surface (435b) may be arranged to surround the second surface (430b).

[0131] In the present embodiment, the plate (430) can be coupled to the second pin unit (420) regardless of the vertical direction of the plate (430).

[0132] As another example, referring to (b) of FIG. 8, the plate (430) may include only the first connecting surface (435a). That is, one end of the peripheral surface (434) may be connected to the first surface (430a) by the first connecting surface (435a), and the other end of the peripheral surface (434) may be directly connected to the second surface (430b).

[0133] In this case, the plate (430) can be coupled with the second pin unit (420) with the first connecting surface (435a) of the plate (430) positioned on the upper side. Then, the first surface (430a) can come into contact with the guide member (230).

[0134] Meanwhile, the guide member (230) may include a body portion (231) forming the second pin slot (232) and an extension portion (233) extending horizontally from the opening side end of the body portion (231).

[0135] The second pin slot (232) is opened in the lower direction of the body part (231), and the extension part (233) can extend from the lower end of the body part (231).

[0136] The above body part (231) is inserted into the first door (21), and at least a portion of the extension part (233) can protrude outward from the first door (21).

[0137] When the first door (21) is assembled with the second pin unit (420) while the plate (430) is coupled with the second pin unit (420), the extension (233) can come into contact with the plate (430). When the first and second pins (421a, 422a) are inserted into the second pin slot (232), the upper portions of the first and second pins (421a, 422a) can be spaced apart from the upper portion of the body portion (231).

[0138] The maximum width (W) of the plate (430) may be greater than the width of the extension (233). Accordingly, the contact area between the plate (430) and the extension (233) increases, so that wear due to friction in a state where the load is concentrated on a specific portion of the extension (233) can be reduced.

[0139] Fig. 10 (a) is a perspective view showing a state in which a height-adjusting component according to the first embodiment is coupled to a first pin, and Fig. 10 (b) is a perspective view showing a state in which a height-adjusting component according to the first embodiment is coupled to a second pin.

[0140] Fig. 11 is a cross-sectional view showing a state in which a height-adjusting component according to the first embodiment is coupled to a first pin.

[0141] Referring to FIGS. 10 and 11, in the present embodiment, in order to adjust the height of the first door (21), a height-adjusting component (460) can be coupled to at least one of the first pin (421a) and the second pin (421b).

[0142] The above height-adjusting component (460) may be, for example, a “C”-shaped clip. The above height-adjusting component (460) may be formed of a metal material and may be elastically deformable by external force.

[0143] The height adjustment component (460) can be connected to the first pin (421a) or the second pin (421b) by inserting the first pin (421a) or the second pin (421b) into the space formed by the height adjustment component (460).

[0144] In the present embodiment, when the plate (430) is coupled to the second pin unit (420), the plate (430) can move in the longitudinal direction (for example, up and down direction) of the first pin (421a) or the second pin (421b).

[0145] Accordingly, when the height-adjusting component (460) is coupled to the second pin unit (420) so that the height-adjusting component (460) is positioned between the plate (430) and the flange (423), the height of the first door (21) can be increased by the thickness of the height-adjusting component (460). In addition, when the height-adjusting component (460) coupled to the first pin (421a) or the second pin (421b) is separated, the height of the first door (21) can be decreased by the thickness of the height-adjusting component (460).

[0146] The height of the first door (21) can be increased or decreased as the number of the height adjustment parts (460) increases or decreases.

[0147] According to this embodiment, the height of the first door (21) can be adjusted by connecting the height-adjusting component (460) to the second pin unit (420) or by separating the height-adjusting component (460) connected to the second pin unit (420), so there is an advantage in that the height of the first door (21) can be adjusted in a simple manner.

[0148] Figure 12 (a) is a drawing showing the positions of the pin unit and the pin slot when the first door is closed, and Figure 12 (b) is a drawing showing the positions of the pin unit and the pin slot when the first door is opened to the maximum opening angle.

[0149] FIG. 12 schematically illustrates, as an example, a state in which the second hinge mechanism is viewed from below.

[0150] Referring to Fig. 12, when the door (20) is closed, the gasket (214) on the rear side of the door (20) can remain in close contact with the front side of the cabinet (10). When the refrigerator is installed indoors, the cabinet (10) and the first door (21) can be placed close to each other.

[0151] Meanwhile, the second pin slot (232) may include a plurality of distinct passes (401, 402, 403, 404, 405).

[0152] When the first door (21) is closed, the first pin (421a) and the second pin (421b) can be positioned in the first pass (401). That is, the first pin (421a) and the second pin (421b) can be positioned at both ends of the first pass (401). In particular, the second pin (421b) can be positioned at the intersection of an arc forming the first pass (401) and the second pass (402). Therefore, the second pin (421b) can be moved to the second pass (402) at the moment when the opening of the first door (21) begins.

[0153] Meanwhile, when the center of rotation of the first door (21) is positioned at the corners of the side and front of the first door (21) where interference with the furniture (P) is expected first when the first door (21) starts to open, interference between the first door (21) and the furniture (P) can be prevented.

[0154] Accordingly, the center of rotation of the first door (21) at the moment when the opening of the first door (21) begins can be positioned adjacent to the front and side edges of the first door (21).

[0155] Meanwhile, when the user pulls the first door (21) to open the first door (21), the first door (21) may start to open as it moves forward and to the right in the direction of the first pass (401).

[0156] The moment the opening of the first door (21) begins, the first pin (421a) can move from the first pass (401), and the second pin (421b) can enter the second pass (402).

[0157] Since the first pin (421a) and the second pin (421b) are positioned in the first pass (401) and the second pass (402) extending in different directions, the opening operation of the first door (21) is accurately performed while the rotational force is transmitted by the rotation operation without the first door (21) being twisted or slipping.

[0158] When the second pin (421b) enters and moves into the second pass (402), the door (20) can rotate while moving slightly forward and to the right, and thus, the separation of the gasket (214) adhered to the front of the cabinet (10) can be made more easily. That is, interference by the gasket (214) adhered to the cabinet (10) when the first door (21) rotates can be prevented, and the subsequent rotational motion of the first door (21) can be made more smooth.

[0159] When the first door (21) is further opened, the first pin (421a) can be positioned in the first pass (401) and the second pin (421b) can enter the third pass (403). That is, the second pass (402) can be positioned between the first pin (423a) and the second pin (421b).

[0160] When the first door (21) is further opened, the first pin (421a) can be moved to the second pass (402) and the second pin (421b) can be moved to the fourth pass (404). That is, the third pass (403) can be positioned between the first pin (421a) and the second pin (421b).

[0161] When the first door (21) is further opened, the first pin (421a) can be moved along the third pass (403) and the second pin (421b) can be moved along the fourth pass (404).

[0162] When the door (20) is further opened, the first pin (421a) can be moved to the fourth pass (404) and the second pin (421b) can be moved to the fifth pass (405).

[0163] When the door (20) is fully opened to a state as shown in (b) of FIG. 12, the angle between the front of the cabinet (10) and the rear of the door (20) may be approximately 110°. At this time, the first pin (421a) may be moved along the fourth pass (404), and the second pin (421b) may be moved to the end of the fifth pass (405).

[0164] Since the centers of curvature of adjacent two passes in the above multiple passes are different, the center of rotation of the first door (21) moves during the opening process of the first door (21), so that the opening angle of the first door (21) can be secured without the first door (21) interfering with the furniture.

[0165] Figures 13 and 14 are drawings showing various variations of the plate of the first embodiment.

[0166] First, referring to (a) of FIG. 13, a plate (470) of one modified example may include a first hole (471) and a second hole (472).

[0167] One of the first hole (471) and the second hole (472) may be formed in a circular shape, and the other may be formed in an elliptical shape or a shape similar to an ellipse. That is, the first hole (471) and the second hole (472) may be formed in different shapes.

[0168] In this case, despite the manufacturing tolerance of the plate (470) and the first and second pins (421a, 422a) and the assembly tolerance of the plate (470) and the first and second pins (421a, 422a), there is an advantage in that the plate (470) can be assembled, and after assembly, the horizontal movement of the plate (470) can be restricted.

[0169] Referring to (b) of FIG. 13, a plate (480) of another modified example may include a single hole (481). The single hole (481) may be formed to be long in the longitudinal direction of the plate (480). At least one of the two ends of the hole (481) may be formed in a round shape. For example, each of the two ends of the hole (481) may be formed in a round shape. That is, the hole (481) may include a first curved portion (481a) and a second curved portion (481b).

[0170] The curvature of each of the first curved portion (481a) and the second curved portion (481b) may be the same as or similar to the curvature of the first pin (421a) or the second pin (421b).

[0171] When the plate (480) is coupled with the second pin unit (420), the first curved portion (481a) can contact or come into proximity with one of the first pin (421a) and the second pin (421b), and the second curved portion (481b) can contact or come into proximity with the other of the first pin (421a) and the second pin (421b).

[0172] Referring to (c) of FIG. 13, another variation of the plate (483) may include a hole (484) into which either the first pin (421a) or the second pin (421b) can be coupled, and an opening (485) (or cutout) providing a space in which the other one is positioned.

[0173] The above hole (484) may be a closed type hole, and the above opening (485) may be an open type hole.

[0174] The above opening (485) may include a curved portion (485a). The curvature of the curved portion (485a) may be the same as or similar to the curvature of the first pin (421a) or the second pin (421b).

[0175] Referring to (a) of FIG. 14, another modified example of the plate (490) may include a first opening (491) and a second opening (492). A first pin (421a) may be inserted into one of the first opening (491) and the second opening (492), and a second pin (421b) may be inserted into the other.

[0176] The first opening (491) and the second opening (492) may be open-type holes. The first opening (491) and the second opening (492) may extend or be open in the same direction.

[0177] The first opening (491) may include a first curved portion (491a), and the second opening (492) may include a second curved portion (492a).

[0178] The curvature of each of the first curved portion (491a) and the second curved portion (492a) may be the same as or similar to the curvature of the first pin (421a) or the second pin (421b).

[0179] Referring to (b) of FIG. 14, another modified example of the plate (495) may include a first opening (496) and a second opening (497). A first pin (421a) may be inserted into one of the first opening (496) and the second opening (497), and a second pin (421b) may be inserted into the other.

[0180] The first opening (496) and the second opening (497) may be open-type holes. The first opening (496) and the second opening (497) may extend or open in different directions. Alternatively, the first opening (496) and the second opening (497) may be opened in opposite directions.

[0181] The first opening (496) may include a first curved portion (496a), and the second opening (497) may include a second curved portion (497a).

[0182] The curvature of each of the first curved portion (497a) and the second curved portion (497a) may be the same as or similar to the curvature of the first pin (421a) or the second pin (421b).

[0183] Figure 15 is a perspective view showing the first hinge mechanism and the second hinge mechanism of the second embodiment.

[0184] This embodiment is identical to the first embodiment in other respects, except that the shape of the guide member is different. Therefore, only the characteristic parts of this embodiment will be described below.

[0185] Referring to FIG. 15, the first hinge mechanism (60) of the present embodiment may include a first hinge body (610) and a first pin unit (620).

[0186] The first pin unit (620) may, for example, extend from the first hinge body (610) toward the first door (21). The first pin unit (620) may extend downward from the first hinge body (610).

[0187] The first pin unit (620) may include a first pin (621) and a second pin (622). The first pin (621) and the second pin (622) may be spaced apart from the first hinge body (610).

[0188] The basic shape and function of the first pin (621) and the second pin (622) are the same as the first pin and the second pin of the first embodiment, so a detailed description thereof will be omitted.

[0189] The first door (21) may include a guide member (630). The guide member (630) may form a pin slot.

[0190] The pin slot may include a first slot (640) in which the first pin (621) is received, and a second slot (650) in which the second pin (622) is received. The first slot (640) and the second slot (650) may be spaced apart from each other and arranged in a partitioned manner.

[0191] The above guide member (630) may include an extension portion (631) that is fastened to the first door (21). A fastening hole (632) through which a fastening member passes may be formed in the extension portion (631). The fastening member may be fastened to the first door (21) by passing through the fastening hole (632).

[0192] The above guide member (630) may include a first body part (633) forming the first slot (640) and a second body part (634) forming the second slot (650). The first body part (633) and the second body part (634) may extend from the extension part (631).

[0193] The second hinge mechanism (50) of the present embodiment may include a second hinge body and a second pin unit (520).

[0194] The second hinge body may include, for example, a coupling portion (511) coupled to the cabinet (10) and an extension portion (512) extending from the coupling portion (511). The second pin unit (520) may be provided in the extension portion (512).

[0195] The second pin unit (520) may, for example, extend from the second hinge body (510) toward the first door (21). The second pin unit (520) may extend upward from the extension portion (412).

[0196] The second pin unit (520) may include a first pin (521) and a second pin (522). The first pin (521) and the second pin (522) may be spaced apart from the second hinge body (510).

[0197] The basic form and function of the first pin (521) and the second pin (522) are the same as the first pin and the second pin of the first embodiment, so a detailed description thereof will be omitted.

[0198] The first door (21) may include a guide member (550). The guide member (550) may form a pin slot.

[0199] The pin slot may include a first slot (560) in which the first pin (521) is received, and a second slot (570) in which the second pin (522) is received. The first slot (560) and the second slot (570) may be spaced apart from each other and arranged in a partitioned manner.

[0200] The above guide member (550) may include an extension portion (551) that is fastened to the first door (21). A fastening hole (552) through which a fastening member passes may be formed in the extension portion (551). The fastening member may be fastened to the first door (21) by passing through the fastening hole (552).

[0201] The above guide member (550) may include a first body part (553) forming the first slot (560) and a second body part (554) forming the second slot (570). The first body part (553) and the second body part (554) may extend from the extension part (551).

[0202] The rotation center of the first door (21) can also be moved by the first hinge mechanism and the second hinge mechanism of the present embodiment.

[0203] Meanwhile, the plate (430) can be combined with the second pin unit (520).

[0204] When the above plate (430) is combined with the second pin unit (520), the plate (430) can come into contact with the fastening portion (551).

[0205] When the plate (430) is coupled with the second pin unit (520), a portion of the plate (430) may overlap with the first slot (560) in the vertical direction, and another portion may overlap with the second slot (570) in the vertical direction.

[0206] In this embodiment, wear of the guide member (550) can be reduced by the plate (430).

[0207] Another example is proposed.

[0208] In cases where the area or diameter of the flange (423) is small, there is a concern that the load will be concentrated on the flange (423), and thus, the wear of the guide member (230) in contact with the flange (423) may increase. Therefore, it may be additionally considered to omit the plate (430) and increase the contact area between the flange (423) and the guide member (230).

[0209] For example, the diameter of the first flange of the first hinge pin may be formed to be equal to or greater than the width (width of the extension) of the guide member (230). In addition, the diameter of the second flange of the second hinge pin may be formed to be equal to or greater than the width (width of the extension) of the guide member (230). Alternatively, the diameter of either the first flange or the second flange may be formed to be equal to or greater than the width (width of the extension) of the guide member (230).

[0210] Alternatively, the flange of the first hinge pin and the flange of the second hinge pin may be formed integrally to increase the contact area between the flange and the guide member. That is, it is also possible to have the first pin and the second pin extend from a single flange. In this case, the flange may also be formed in a shape identical to or similar to that of the plate.

[0211] For example, the flange may be formed in an elliptical or elliptical-like shape. In addition, the maximum width of the flange may be formed to be equal to or greater than the width of the guide member (230) (width of the extension).

[0212] On the other hand, unlike the above-described case, even when the pin unit is formed in a form including a single pin, it is also possible to provide a plate between the flange and the guide member to increase the contact area between the flange of the pin unit and the guide member. In this case, the plate can contact the guide member while allowing the single pin to penetrate therethrough.

[0213] As another example, it is also possible for the first plate to be coupled to the first pin or seated on the first flange, and the second plate to be coupled to the second pin or seated on the second flange. In this case, the diameter or maximum width of the first plate may be greater than the diameter or maximum width of the first flange. The diameter or maximum width of the second plate may be greater than the diameter or maximum width of the second flange.

[0214] It is also possible for the first plate to contact the second plate, or for a portion of the first plate to be coupled or engaged with a portion of the second plate, so that the first plate and the second plate do not rotate or move about each pin.
