[0001] This specification relates to a refrigerator.

[0002] In general, a refrigerator is a home appliance that allows food to be stored at low temperatures 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 refrigerators are gradually becoming larger and more multifunctional in line with the trend of changing eating habits and higher-end products, and refrigerators equipped with various structures and convenient devices that take user convenience into consideration are being released.

[0005] Recently, refrigerators with thinner doors have been developed to minimize the protrusion from the cabinet when installed in a cabinet. Furthermore, hinge structures are being developed to prevent the door from interfering with surrounding structures, such as the cabinet, during the opening process.

[0006] In this regard, there is a prior document, Japanese Patent Application Laid-Open No. 2022-125452.

[0007] In the case of prior literature, when a dispenser is installed on a door or an ice maker is installed on a door, a structure for introducing a water pipe to supply water to the door into the door is not disclosed.

[0008] One embodiment provides a refrigerator in which a water pipe can be introduced into the door as the opening angle of the door increases.

[0009] Optionally or additionally, one embodiment provides a refrigerator in which bending of a water pipe is reduced during the opening and closing process of the door.

[0010] Alternatively or additionally, one embodiment provides a refrigerator in which the water pipe is minimally exposed to the outside when the door is open.

[0011] Optionally or additionally, one embodiment provides a refrigerator in which wires and water pipes introduced into the door are prevented from interfering with each other during the opening and closing process of the door.

[0090] Hereinafter, some embodiments of the present invention will be described in detail with reference to exemplary drawings. When designating components in each drawing, it should be noted that, where possible, identical components will be given the same reference numerals, even if they appear in different drawings. Furthermore, when describing embodiments of the present invention, detailed descriptions of related known structures or functions will be omitted if they are deemed to hinder understanding of the embodiments of the present invention.

[0091] Additionally, in describing components of embodiments of the present invention, terms such as first, second, A, B, (a), (b), etc. may be used. These terms are only intended to distinguish the components from other components, and the nature, order, or sequence of the components are not limited by the terms. When it is described that a component is "connected," "coupled," or "connected" to another component, it should be understood that the component may be directly connected, coupled, or connected to the other component, but another component may also be "connected," "coupled," or "connected" between each component.

[0092] Before explaining, let's define the direction. In the embodiment of the present invention, the direction in which the front of the door as shown in FIG. 1 is facing or the direction from the cabinet toward the door can be defined as front, the direction toward the cabinet based on the front of the door can be defined as rear, the direction toward the floor surface on which the refrigerator is installed can be defined as downward, and the direction away from the floor surface can be defined as upward. When discussing undefined directions, the directions can be defined and explained based on each drawing.

[0093] FIG. 1 is a perspective view of a refrigerator according to a first embodiment, (A) of FIG. 2 is a plan view of the refrigerator according to the first embodiment, and (B) of FIG. 2 is an enlarged view of part A of FIG. 1.

[0094] Referring to FIGS. 1 and 2, the refrigerator (1) according to the present embodiment may be installed independently in a kitchen or housed within a furniture cabinet (or wall) indoors. When the refrigerator (1) is installed within a furniture cabinet indoors, the refrigerator (1) may be installed alone or arranged left and right together with other refrigerators.

[0095] 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.

[0096] The above storage space is not limited, but can be divided into a first space (11) on the upper side and a second space (12) on the lower side.

[0097] The above door (20) may 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).

[0098] The first space (11) may be a refrigerator and the second space (12) 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, and a single door may open and close the storage space.

[0099] At least one of the first door (21) and the second door (22) may be a rotary type door. Alternatively, a single door (20) may be a rotary type door.

[0100] In this embodiment, an example will be described in which two first doors (21) are arranged left and right. It should be noted that the description of "first door (21)" below can be applied to a door having a component that supplies or uses water.

[0101] The above first door (21) can be rotatably connected to the cabinet (10) by a first hinge mechanism (30) and a second hinge mechanism (40).

[0102] 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.

[0103] The first hinge mechanism (30) and the second hinge mechanism (40) can open the first door (21) by moving the rotation center (which may also be referred to as a virtual rotation center) of the first door (21).

[0104] When the center of rotation of the first door (21) moves, the opening angle can be increased while preventing the first door (21) from interfering with the furniture during the opening process of the first door (21). The first door (21) can be opened at an angle of at least 90 degrees.

[0105] The first hinge mechanism (30) may include a first hinge body (310). The first hinge body (310) may be coupled to the upper side or front side of the cabinet (10) and may be connected to the upper side of the first door (21). A portion of the first hinge body (310) may overlap the upper side of the first door (21) in a vertical direction.

[0106] The first hinge mechanism (30) may further include a first pin unit (320) (see FIG. 5). The first pin unit (320) may be coupled to the first hinge body (310) or formed integrally with the first hinge body (310). The first pin unit (320) may be accommodated in a first slot (212) (see FIG. 3) provided in the first door (21).

[0107] The second hinge mechanism (40) may include a second hinge body (410). The second hinge body (410) is coupled to the front or lower side of the cabinet (10) and may be connected to the lower side of the first door (21). A portion of the second hinge body (410) may overlap the lower side of the first door (21) in the vertical direction.

[0108] The second hinge mechanism (40) may further include a second pin unit (420). The second pin unit (420) may be coupled to the second hinge body (410) or formed integrally with the second hinge body (410). The second pin unit (420) may be accommodated in a second slot (220) provided in the first door (21).

[0109] The first door (21) may further include a dispenser (23). The dispenser (23) is a component that receives water. The dispenser (23) can discharge the supplied water. If the first door (21) additionally includes an ice maker, the dispenser (23) can also discharge ice. The ice maker is also a component that receives water. The ice maker can receive water and use the water to produce ice.

[0110] In order for the above dispenser (23) to discharge water, the dispenser (23) may be directly or indirectly connected to a water pipe (61). If the dispenser (23) is configured to discharge a liquid other than water, the water pipe (61) may be replaced with a liquid pipe through which the liquid flows. The ice maker may also be directly or indirectly connected to the water pipe (61).

[0111] The above water pipe (61) can be drawn out from the inside of the cabinet (10) through the water pipe opening (15) and then introduced into the inside of the first door (21). Alternatively, the water pipe (61) can also be introduced directly from the outside of the cabinet (10) into the inside of the first door (21).

[0112] The first door (21) may be provided with a component that operates to discharge water and / or ice, although not shown. The component may be electrically connected to a wire (62). Alternatively, separately from the component, the first door (21) may include one or more of a display unit, an input unit, a sensor unit, and a door-side control unit, and one or more of the display unit, the input unit, the sensor unit, and the door-side control unit may be electrically connected to the wire (62).

[0113] For example, the wire (62) is connected to a controller provided in the cabinet (10), and can be introduced into the first door (21) and connected to the component directly or indirectly (when connected to a separate wire provided inside the first door).

[0114] It should be noted that in this specification, the fact that the water pipe (61) and / or the wire (62) is introduced into the first door (21) or the cabinet (10) is also interpreted as the fact that the water pipe (61) and / or the wire (62) is withdrawn from the first door (21) or the cabinet (10).

[0115] Fig. 3 is a drawing of a first hinge mechanism according to the first embodiment as viewed from the rear side of the refrigerator, and Fig. 4 is a plan view showing a state in which the first hinge mechanism according to the first embodiment is installed in the refrigerator. Fig. 5 is a cross-sectional view taken along line 5-5 of Fig. 3.

[0116] Referring to FIGS. 2 to 5, the upper wall (101) of the cabinet (10) may be provided with a water pipe opening (15) through which the water pipe (61) passes. The upper wall (101) may be provided with a guide member that is inserted into the water pipe opening (15) to guide the passage of the water pipe (61).

[0117] The above water pipe opening (15) may be located at the rear of the first hinge body (310). The water pipe (61) may extend forward after being withdrawn from the water pipe opening (15). For example, the water pipe (61) may extend along the upper side of the first hinge body (310) and then pass through the first door (21).

[0118] The first door (21) may include a first pin slot (212) in which the first pin unit (320) is received. The first pin slot (212) may be formed by a portion of the first door (21) being sunken. That is, the first pin slot (212) may be formed by a wall forming the first pin slot. Alternatively, the first pin slot (212) may be formed in a first guide member (213) coupled to the first door (21). The first pin slot (212) may be formed by a wall of the first guide member (213).

[0119] The first door (21) may include a hinge receiving portion (211) for positioning the first hinge body (310). The hinge receiving portion (211) may be formed by recessing a portion of the upper surface of the first door (21) downward. Alternatively, the hinge receiving portion (211) may be formed by recessing a portion of the rear surface of the first door (21) toward the front.

[0120] The first pin slot (212) may be provided at the bottom of the hinge receiving portion (211).

[0121] The first pin unit (320) may include one or more pins accommodated in the first pin slot (212). For example, FIG. 5 illustrates that the first pin unit (320) includes a first pin (321) and a second pin (322) that are spaced apart from each other. Alternatively, the first pin (321) and the second pin (322) may be connected by a connecting member. In this case, it may also be understood that the first pin unit (320) includes a single pin. The single pin may be formed in a non-circular shape, but may include a curve so as not to interfere with the wall forming the first pin slot (212) during the opening process of the first door (21).

[0122] The first pin (321) and the second pin (322) can extend downward from the first hinge body (310).

[0123] When the first door (21) is opened while the first pin (321) and the second pin (322) are accommodated in the first pin slot (212), the rotation center of the first door (21) can be moved by the shape of the first pin slot (212).

[0124] The curvature of the first pin slot (212) may be continuously variable or stepwise variable. Depending on the shape of the first pin slot (212), the center of rotation may move continuously or stepwise.

[0125] The above first pin unit (320) can extend downward from a portion located on the upper side of the first door (21) in the first hinge body (310).

[0126] The first door (21) may include a first opening (216) through which the water pipe (61) passes. The first opening (216) may be referred to as a door water pipe opening. The water pipe (61) may extend substantially horizontally from the cabinet (10) to the upper side of the first door (21) and then be bent downward to pass through the first opening (216).

[0127] The above water pipe (61) can be pulled out from the cabinet (10) directly behind the first hinge mechanism (30) and extended toward the first opening (216). Therefore, the bending amount of the water pipe (61) can be reduced when the first door (21) is closed.

[0128] The first opening (216) may be positioned outside the first pin slot (212). The first opening (216) may be positioned adjacent to the first pin slot (212).

[0129] In the present embodiment, since the center of rotation of the first door (21) moves, the position of the first opening (216) can be changed when the first door (21) rotates. Since the water pipe (61) passes through the first opening (216), the water pipe (61) can also move, for example, in a horizontal direction, during the rotation of the first door (21).

[0130] To enable movement of the water pipe (61) within the first opening (216), the size or diameter of the first opening (216) may be larger than the size or diameter of the water pipe (61).

[0131] By reducing the amount of movement of the water pipe (61), the amount of bending of the water pipe (61) can also be reduced. In order to reduce the amount of movement of the water pipe (61), it is preferable that the first opening (216) be positioned adjacent to the center of rotation.

[0132] As will be described later, the center of rotation can move in a direction closer to the first pin unit (320) in at least a portion of the entire open section of the first door (21). Therefore, in the present embodiment, the first opening (216) can be positioned adjacent to the first pin unit (320).

[0133] For example, the first door (21) may include a first side (21c) positioned adjacent to the first hinge body (310) on both sides. The first side (21c) may be adjacent to the furniture shelf.

[0134] The first pin slot (212) may extend in a curved shape and include a first end (212a) and a second end (212b). Although not limited, the first pin slot (212) may be formed in a convex shape toward the cabinet (10) from the front surface (21a) of the first door (21) when viewed from the upper surface of the first door (21).

[0135] The first end (212a) may be positioned closer to the first side (21c) than the second end (212b). The second end (212b) may be positioned closer to the front side (21a) of the first door (21) than the first end (212a).

[0136] When the first door (21) is closed, the first pin (321) can contact the second end (212b) or be close to the second end (212b). When the first door (21) is opened to the maximum angle, the second pin (322) can contact the first end (212a) or be close to the first end (212a).

[0137] The above first opening (216) may include a portion positioned closer to the front surface (21a) of the first door (21) than the first pin unit (320).

[0138] The above first opening (216) may include a portion positioned closer to the front surface (21a) of the first door (21) than the above first pin slot (212).

[0139] The first opening (216) may include a portion positioned between the first end (212a) and the second end (212b). That is, when the first end (212a) and the second end (212b) are connected in a straight line, the straight line may overlap the first opening (9216) in the vertical direction.

[0140] The above first opening (216) may include a portion positioned closer to the cabinet (10) than the first end (212a) and the second end (212b).

[0141] The first opening (216) may include a portion that is positioned further from the first side (21c) than the first end (212a). The first opening (216) may include a portion that is positioned closer to the first side (21c) than the second end (212b).

[0142] The above refrigerator (1) may further include a hinge cover (350) that covers at least a portion of the first hinge body (310).

[0143] The above hinge cover (350) can cover at least a portion of the first hinge body (310) that overlaps with the first door (21). The hinge cover (350) can be mounted on the first hinge body (310) or mounted on the first door (21).

[0144] The above water pipe (61) can pass through the first opening (216) while being positioned in the internal space formed by the hinge cover (350). That is, the hinge cover (350) can cover the water pipe (61) that has passed through the first opening (216). In this case, since the state in which the hinge cover (350) covers the water pipe (61) is maintained during the opening and closing process of the first door (21), the external exposure of the water pipe (61) can be reduced.

[0145] The above first hinge body (310) may include a first bent portion (312) and a second bent portion (314) that are spaced apart.

[0146] Based on the closed state of the first door (21), the first bending portion (312) may be formed on the side of the first body end adjacent to the first side (21c) of the first hinge body (310), and the second bending portion (312) may be formed on the side of the second body end located on the opposite side of the first body end.

[0147] The first bending portion (312) and the second bending portion (314) can be bent so as to protrude upward from the first hinge body (310).

[0148] The first bend portion (312) and the second bend portion (314) above can serve as reinforcing portions. The first bend portion (312) and the second bend portion (314) above can serve as restrictors to limit the displacement of the water pipe (61). For example, the water pipe (61) can be positioned between the first bend portion (312) and the second bend portion (314).

[0149] The above hinge cover (350) can be positioned to cover both sides of the first hinge body (310). The first bending portion (312) and the second bending portion (314) can primarily limit the horizontal movement of the water pipe (61). The hinge cover (350) can secondarily limit the horizontal movement of the water pipe (61).

[0150] The hinge cover (350) may cover the upper side of the first opening (216) so as to reduce the exposure of the water pipe (61). For example, the hinge cover (350) may include a portion that overlaps the first opening (216) in the vertical direction.

[0151] When the water pipe (61) passes through the first opening (216), the water pipe (61) can overlap with the first pin unit (320) in the vertical direction. For example, the water pipe (61) can overlap with the second pin (322) in the vertical direction.

[0152] The first door (21) may further include a second opening (218) (see FIG. 12) through which the wire (62) passes. The second opening (218) may also be referred to as a door wire opening. The second opening (218) may also be provided in the hinge receiving portion (211).

[0153] In this embodiment, one or more wires (62) may penetrate the first door (21) individually or in a bundle. Hereinafter, they will be collectively referred to as “wires (62)” without distinction of shape.

[0154] The above wire (62) can penetrate the first door (21) at a position horizontally spaced from the first opening (216). In the present embodiment, the first opening (216) can be positioned closer to the first side (21c) than the second opening (218).

[0155] The first pin slot (212) may be positioned closer to the first side (21c) than the second opening (218).

[0156] The above refrigerator (1) may further include a guide unit (50) that guides the wire (62).

[0157] The above guide unit (50) may include a first guide (510) that accommodates the wire (62). The above guide unit (50) may further include a second guide (550) that guides the movement of the first guide (510).

[0158] The first guide (510) may be connected to the first door (21). For example, one side of the first guide (510) may be connected to the first door (21) by a connection unit (520, 530). The other side of the first guide (510) may be connected to the second guide (550).

[0159] The second guide (550) may be installed in the cabinet (10). For example, the second guide (550) may be installed in the upper wall (101) of the cabinet (10).

[0160] The above wire (62) can be connected to the controller at the upper side of the cabinet (10). The above wire (62) can be bent after extending to the rear of the cabinet (10) and accommodated in the first guide (510) at the rear side of the first guide (510).

[0161] The above first guide (510) can not only receive the wire (62) and protect the wire (62), but also reduce the exposure of the wire (62) during the opening process of the first door (21).

[0162] When the first door (21) is closed, a part of the first guide (510) may overlap the cabinet (10) in the vertical direction, and another part may overlap the upper side of the first door (21) in the vertical direction. At this time, the length of a part of the first guide (510) may be longer than the length of the other part.

[0163] When the first door (21) is closed, the first guide (510) may include a portion extending in a straight line. Referring to FIG. 4, the first guide (510) may extend in a straight line in the forward and backward directions. Accordingly, the wire (62) may be guided in a straight line toward the first door (21) within the first guide (510).

[0164] FIG. 6 is a drawing showing the internal configuration of a first door according to the first embodiment, and FIG. 7 is a cross-sectional view taken along line 7-7 of FIG. 6.

[0165] Referring to FIGS. 6 and 7, a guide tube (240) may be provided inside the first door (21) to guide a water pipe (61) passing through the first opening (216). The guide tube (240) may be connected from the first opening (216) side to the dispenser (23) side. The guide tube (240) may be formed in a tube shape including a hollow portion therein. Alternatively, a guide or bushing may be provided extending downward from the first opening (216) side, and the guide or bushing may be connected to the guide tube (240) or inserted into the guide tube (240).

[0166] The interior of the first door (21) may be provided with insulation for thermal insulation. The insulation may be formed, for example, by injecting and hardening a foaming agent. The guide tube (240) may limit the water pipe (61) from contacting the insulation.

[0167] The above guide tube (240) may, for example, be in contact with or connected to the bottom of the hinge receiving portion (211). The size or diameter of the guide tube (240) may be larger than the size or diameter of the water pipe (61). Therefore, during the opening and closing process of the first door (21), the water pipe (61) can move within the guide tube (240).

[0168] Since the above water pipe (61) passes through the first opening (216) in a bent state while being positioned higher than the second pin (322), the radius of the bent portion of the water pipe (61) can be increased, thereby reducing the amount of bending.

[0169] The water pipe (61) guided by the above guide tube (240) may be connected to a component, for example, a valve, that controls the flow of water within the first door (21). A separate tube may be connected to the valve, and this tube may be connected to the dispenser (23).

[0170] The first door (21) may further include an ice-making chamber wall (250) forming an ice-making chamber. The ice-making chamber may be equipped with an ice maker for producing ice. In this case, a door tube (65) may be provided within the first door (21) to receive water from the water pipe (61) and guide the water to the ice maker.

[0171] At least a portion of the above wire (62) may be guided by the guide tube (240). Alternatively, a wire tube for guiding the wire (62) may be additionally provided inside the first door (21).

[0172] Fig. 8 (A) is a perspective view of the hinge cover according to the first embodiment as viewed from above, and Fig. 8 (B) is a perspective view of the hinge cover according to the first embodiment as viewed from below.

[0173] Referring to FIGS. 5, 7, and 8, the hinge cover (350) may include a first wall (351). The first wall (351) may be positioned on the upper side of the hinge receiving portion (211) of the first door (21).

[0174] The hinge cover (350) may further include a second wall (352) extending downward from the first wall (351). The second wall (352) may, for example, extend from a portion of the edge of the first wall (351).

[0175] The above hinge cover (350) may further include a coupling portion (355) coupled to a frame (not shown) installed in the cabinet (10). The frame may cover a portion of the hinge body (310) coupled to the cabinet (10). Alternatively, the coupling portion (355) may be directly coupled to the cabinet (10).

[0176] The first wall (351) and the second wall (352) of the hinge cover (350) may form a space (353). A portion of the first hinge body (310) and the water pipe (61) may be accommodated in the space (353). In the space (353), the water pipe (61) may be positioned between the first hinge body (310) and the first wall (351).

[0177] The hinge cover (350) may include a first aperture (354) through which the water pipe (61) passes. For example, the first aperture (354) may be formed in the connecting portion (355) or may be formed by the opening of the second wall (352).

[0178] The above hinge cover (350) may further include a second opening (356) through which the water pipe (61) passes. For example, the first opening (354) may be a side opening, and the second opening (356) may be a lower opening.

[0179] The first wall (351) may overlap with at least a portion of the first pin unit (320) in the vertical direction. The first wall (351) may overlap with the first opening (216) in the vertical direction.

[0180] In a state where the hinge cover (350) covers the first hinge body (310), the second wall (352) can cover the first bending portion (312) and the second bending portion (314) from the side.

[0181] Fig. 9 is a perspective view of a guide unit according to the first embodiment, Fig. 10 is a perspective view showing a first connecting member according to the first embodiment, and Fig. 11 is a perspective view showing a second connecting member according to the first embodiment. Fig. 12 is a cross-sectional view taken along line 12-12 of Fig. 4.

[0182] Referring to FIGS. 9 to 12, the first guide (510) may be formed in a tube shape forming a space (515) inside.

[0183] The above first guide (510) may include an inlet (512a) and an outlet (512b). The inlet (512a) and the outlet (512b) may also be used as opposite concepts.

[0184] The first guide (510) may include a first portion (512). The first portion (512) may include the inlet (512a).

[0185] The first guide (510) may further include a second portion (514) that is bent from the first portion (512). The second portion (514) may extend downward from the opposite side of the inlet (512a). The second portion (514) may include the outlet (512b).

[0186] The second part (514) may be provided with an extension (516). The extension (516) may extend horizontally from the outer surface of the second part (514). For example, the extension (516) may extend from the lower end of the second part (514).

[0187] The first guide (510) may further include a coupling portion (518) for coupling with the second guide (550). The coupling portion (518) may, for example, protrude from the first portion (512). The coupling portion (518) may protrude downward from a point adjacent to the inlet (512a) in the first portion (512).

[0188] The above-mentioned connecting portion (518) may include a first part (518a) extending from the first part (512) and a second part (518b) extending downward from the first part (518a).

[0189] The size or diameter of the second part (518b) may be larger than the size or diameter of the first part (518a).

[0190] The second guide (550) may include a base (551). The second guide (550) may further include a barrier extending from the base (551).

[0191] The above barrier may include a first barrier (552) and a second barrier (553) spaced apart from the first barrier (552). The first barrier (552) and the second barrier (553) may form a space for the first guide (510) to be positioned.

[0192] For example, the first barrier (552) and the second barrier (553) may extend in the front-back direction and be spaced apart in the left-right direction.

[0193] The first part (512) may be positioned in the space between the first barrier (552) and the second barrier (553). The distance between the first barrier (552) and the second barrier (553) may be greater than the width (for example, the left-right width) of the first part (512).

[0194] The above first barrier (552) and second barrier (553) can protect the first guide (510) and reduce external exposure.

[0195] The base (551) may include a through hole (554) into which the coupling part (518) is inserted. The base (511) may include a guide hole (555) that guides movement of the coupling part (518). The guide hole (555) may extend from the through hole (554).

[0196] The second part (518b) may pass through the through hole (554). The width of the guide hole (555) may be smaller than the width or diameter of the through hole (554). The width of the guide hole (555) may be larger than the size or diameter of the first part (518a) and smaller than the size or diameter of the second part (518b).

[0197] Accordingly, during the movement process of the first guide (510), the first part (518a) is positioned above the guide hole (555) and the second part (518b) is positioned below the base (551), so that the first guide (510) can be prevented from being separated from the second guide (550).

[0198] The above guide hole (555) may extend from the through hole (554) toward the first door (21). The through hole (554) may be positioned closer to the first barrier (552) than to the second barrier (553). The guide hole (555) may extend from the through hole (554) in a direction closer to the second barrier (553).

[0199] The above guide hole (555) can intersect with each of the first barrier (552) and the second barrier (553). Therefore, when the first door (21) is closed, the first part (512) can be positioned adjacent to the first barrier (552).

[0200] During the opening process of the first door (21), the first part (512) can move in a direction closer to the second barrier (553).

[0201] The second guide (550) may further include a fastening portion (557) for fastening with the cabinet (10). For example, a plurality of fastening portions (557) may extend from the base (551).

[0202] A plurality of ribs (558) may be provided on the lower side of the base (557). The plurality of ribs (558) may reduce the contact area between the base (551) and the cabinet (10). At least a portion of the base (557) may be spaced apart from the upper wall (101) by the plurality of ribs (558). The plurality of ribs (558) may reinforce the strength of the base (551).

[0203] The above guide unit (50) may further include a cover member (562) for covering a portion of the wire (62). The cover member (562) may be combined with the base (551) to form a space in which the wire (62) is positioned. The cover member (562) may be formed in an upwardly convex shape, for example.

[0204] When the wire (62) is positioned between the base (551) and the cover member (562), the upward movement of the wire (62) can be restricted.

[0205] A coupling part (560) for coupling the cover member (562) may be coupled to the base (551). A portion of the cover member (562) may be inserted into the coupling part (560). It should be noted that in the present embodiment, there is no limitation on the coupling method of the cover member (562) and the coupling part (560).

[0206] The above guide unit (50) may further include a third barrier (556). The third barrier (556) may extend from the base (551). The third barrier (556) may limit horizontal movement of a bent portion (first section and second section to be described later) of a wire (62) located on the outside of the first guide (510).

[0207] For example, the third barrier (556) may be positioned on the rear side of the cover member (562). The third barrier (556) may be spaced apart from the first barrier (552). The gap between the third barrier (556) and the first barrier (552) may be greater than the gap between the first barrier (552) and the second barrier (553).

[0208] The above refrigerator (1) may further include a connection unit for connecting the first guide (510) to the first door (21).

[0209] The above connecting unit may include a first connecting member (520) and a second connecting member (530). The connecting unit may enable the first guide (510) to be rotatably connected to the first door (21).

[0210] The above connecting unit is fixed to the first door (21) and can guide the rotation of the first guide (510) when the first guide (510) rotates relative to the first door (21).

[0211] The first connecting member (520) may include a first body (521). The first body (521) may include a first slot (523) in which a portion of the first guide (510) is received.

[0212] The second part (514) of the first guide (510) can be positioned in the first slot (523). When the second part (514) is positioned in the first slot (523), the second part (514) can rotate without interference with the first body (521). Therefore, the first slot (523) can include a curved portion. The wire (62) can pass through the first slot (523).

[0213] The first connecting member (520) may include an extension wall (522) extending from the first body (521). For example, the extension wall (522) may extend downward from a portion of the edge of the first body (521).

[0214] The first connecting member (520) may further include a first hook (525) for coupling to the first door (21). For example, a plurality of first hooks (525) may extend apart from the extension wall (522).

[0215] The above second connecting member (530) may include a second body (531).

[0216] The extension (518) of the first guide (510) may be mounted on the second body (531). The second body (531) may include a second slot (532). The second slot (532) may be aligned with the outlet (512b) of the first guide (510). The second slot (532) may be aligned with the first slot (523). The wire (62) may pass through the second slot (532).

[0217] The first slot (523) and the second slot (532) can be aligned with the second opening (218) of the first door (21).

[0218] The second connecting member (530) may further include a guide wall (534) for guiding the rotation of the extension (518) of the first guide (510) mounted on the second body (531). The guide wall (534) may limit the first guide (510) from moving in a horizontal direction during the rotation of the first guide (510).

[0219] The above guide wall (534) may, for example, protrude from the upper surface of the second body (531). The above guide wall (534) may protrude from a position spaced inward from the edge of the second body (531).

[0220] For example, a plurality of guide walls (534) may be spaced apart from each other. The plurality of guide walls (534) may be positioned facing each other or symmetrically. The plurality of guide walls (534) may include a curved portion (534a) to enable rotation of the extension portion (518).

[0221] Alternatively, a single guide wall (534) may be arranged to surround the extension (518). In this case, the guide wall (534) may also include a curved portion (534a) to allow rotation of the extension (518).

[0222] The second connecting member (530) may further include a second hook (538) for coupling to the first door (21). For example, a plurality of second hooks (538) may extend spaced apart from the second body (531).

[0223] In a state where the first guide (510) is secured to the second body (531), the first connecting member (520) can be secured to the second body (531). For example, the connecting wall (522) can be secured to the second body (531). In a state where the connecting wall (522) is secured to the second body (531), the connecting wall (522) can surround the guide wall (534). That is, in a state where the connecting wall (522) is secured to the second body (531), the guide wall (534) and the extension (518) can be positioned in a space formed by the connecting wall (522).

[0224] When the connecting wall (522) is secured to the second body (531), the extension (518) can be positioned between the first body (521) and the second body (531). Accordingly, the vertical movement of the first guide (510) can be restricted.

[0225] To prevent the first hook (525) from interfering with the second body (531), a groove (536) may be formed at a position corresponding to the first hook (525) in the second body (531). When the connecting wall (522) is secured to the second body (531), the first hook (525) may be positioned in the groove. For example, a second hook (538) may be positioned between two first hooks (525).

[0226] The length of the first hook (525) may be greater than the length of the second hook (538) so that the first hook (525) can be fastened to the first door (21).

[0227] In the first door (21), a receiving groove (217) for receiving the connecting unit may be formed in the hinge receiving portion (211). The receiving groove (217) may be formed by the bottom of the hinge receiving portion (211) being sunken.

[0228] The second opening (218) may be formed at the bottom of the receiving groove (217). The second body (531) may be seated at the bottom of the receiving groove (217). A hook hole (219) may be provided at the bottom of the receiving groove (217) for fastening the first hook (525) and the second hook (538), respectively.

[0229] According to the present embodiment, since the first connecting member and the second connecting member are fixed to the first door (21) by the hook, the first connecting member (520) and the second connecting member (530) can be restricted from moving with respect to the first door (21) during the rotation of the first door (21). On the other hand, the first guide (510) can be rotated with respect to the first door (21) by the first connecting member (520) and the second connecting member (530).

[0230] Fig. 13 (A) is a plan view showing a state in which the first door according to the first embodiment is closed, and Fig. 13 (B) is a plan view showing a state in which the first door according to the first embodiment is opened by a first angle.

[0231] FIG. 14 is a plan view showing a state in which the first door according to the first embodiment is opened to a second angle, FIG. 15 is a plan view showing a state in which the first door according to the first embodiment is opened to a third angle, and FIG. 16 is a plan view showing a state in which the first door according to the first embodiment is opened to a maximum opening angle.

[0232] FIG. 17 is a drawing showing a movement trajectory of a center of rotation during the opening process of the first door according to the first embodiment, and FIG. 18 is a perspective view showing a state in which the first door according to the first embodiment is opened to the maximum opening angle.

[0233] Referring to FIG. 5, FIG. 12 to FIG. 18, when the first door (21) is closed, a portion of the wire (62) located outside the first guide (510) may include a first section (62a) and a second section (62b) bent from the first section (62a). The first section (62a) may extend away from the first guide (510) in a direction away from the front surface (10a) of the cabinet (10). The second section (62b) may be bent from the first section (62a) and may extend in a direction closer to the front surface (10a) of the cabinet (10).

[0234] For example, the first section (62a) and the second section (62b) may be bent to be convex in a direction away from the first door (21). Alternatively, when viewed from the top surface of the cabinet (10), the first section (62a) and the second section (62b) may be arranged in a shape like “∩”.

[0235] In the first door (21), the second opening (218) can be spaced apart from the rotation center (C1) of the first door (21). Therefore, the second opening (218) can move during the opening and closing process of the first door (21).

[0236] The wire (62) penetrating through the second opening (218) also moves during the opening and closing process of the first door (21). For example, during the opening process of the first door (21), the second opening (218) moves away from the cabinet (10), so the length of the wire (62) must increase. In the present embodiment, the portion (first section and second section) located on the outside of the first guide (510) can compensate for the length increased during the opening process of the first door (21), so that damage or breakage of the wire (62) can be prevented.

[0237] As shown in (A) of Fig. 13, when the first door (21) is closed, the center of rotation (C1) can be located at the first door (21). When the first door (21) is closed, the center of rotation (C1) can be located closer to the front surface (21a) of the first door (21) than the first opening (216) and the second opening (218).

[0238] When the first door (21) is closed, the first guide (510) may be perpendicular to the front surface (10a) of the cabinet (10). Alternatively, the first guide (510) may be parallel to the side surface (10b) of the cabinet (10).

[0239] As shown in (B) of Fig. 13, in the process of the first door (21) being opened or opened by the first angle, the center of rotation (C1) can move in a direction away from the front surface (10a) of the cabinet (10).

[0240] The first guide (510) moves along the guide hole (555). When the first door (21) is opened to a first angle, the first guide (510) can be inclined with respect to the side (10b) of the cabinet (10).

[0241] When the first door (21) is opened to the second angle, the center of rotation (C1) can be adjacent to the first opening (216).

[0242] When the first door (21) is opened to the first angle, at least a portion of the second opening (218) may be positioned further from the cabinet (10a) than the first opening (216).

[0243] As shown in Fig. 14, in the process of the first door (21) being opened or opened by the second angle, the center of rotation (C1) can move in a direction closer to the first pin unit (320). In addition, the center of rotation (C1) can move in a direction closer to the cabinet (10).

[0244] As shown in Fig. 15, when the first door (21) is opened or is opened by a third angle, the center of rotation (C1) may move in a direction closer to the first pin unit (320). For example, the third angle may be 90 degrees.

[0245] When the first door (21) is opened to a third angle, the rotation center (C1) may be adjacent to the first pin (321). When the first door (21) is opened to a third angle, the first opening (216) may include a portion that is located further from the front surface (10a) of the cabinet (10) than the rotation center (C1).

[0246] As shown in Fig. 16, when the first door (21) is opened to a maximum opening angle greater than 90 degrees, the rotation of the first door (21) can be restricted.

[0247] In the process of the first door (21) being opened or opened to the maximum opening angle, the center of rotation (C1) can move in a direction away from the first pin (321).

[0248] When the first door (21) is opened to the maximum opening angle, the first guide (510) is positioned on the side of the hinge cover (350) to reduce the exposure of the hinge cover (350). Since the water pipe (61) is positioned within the hinge cover (350), the exposure of the water pipe (61) can be minimized when the first door (21) is opened.

[0249] When the first door (21) is opened to the maximum opening angle, a portion of the first guide (510) may be positioned between the first barrier (552) and the second barrier (553). Therefore, the exposure of the wire (62) may be minimized when the first door (21) is opened. In addition, since the wire (62) is positioned within the first guide (510) when the first door (21) is opened, the user's access to the wire (62) is restricted, and the risk of damage to the wire (62) may be minimized.

[0250] In the process of opening the first door (21), the first opening (216) moves horizontally, but moves closer to the center of rotation (C1), so that the bending amount of the water pipe (61) can be reduced.

[0251] It should be noted that the movement trajectory of the center of rotation disclosed in Fig. 17 is exemplary and is not limited thereto, and may be modified in various ways depending on the shape of the pin slot and pin unit.

[0252] Fig. 19 is a drawing showing the location of the water pipe and the first hinge mechanism according to the second embodiment. Fig. 20 (A) is a drawing showing the first modified example of the second embodiment, and Fig. 20 (B) is a drawing showing the first door according to the first modified example of the second embodiment in an open state.

[0253] This embodiment is identical to the first embodiment in other respects, except that there is a difference in the relative positions of the water pipe and the first hinge mechanism. Therefore, only the characteristic parts of this embodiment will be described below.

[0254] First, referring to FIG. 19, the water pipe (61) of the present embodiment can pass through the first pin slot (612). A first opening (612c) through which the water pipe (61) passes can be formed at the bottom of the first pin slot (612).

[0255] In order to reduce the amount of bending of the water pipe (61) during the opening process of the first door (21), the first opening (612c) may be formed in the same shape as the first pin slot (612) or may include a portion having the same shape as a part of the first pin slot (612).

[0256] The first pin slot (612) may include a first end (612a) and a second end (612b). When the first door (21) is closed, the first pin (321) may contact or be in proximity to the first end (612a). The second pin (322) may be spaced apart from the first pin (321).

[0257] The above water pipe (61) can be spaced apart from the second pin (322) within the first pin slot (612). The above water pipe (61) can be spaced apart from the second end (612b).

[0258] Within the first pin slot (612), the second pin (322) may be positioned between the water pipe (61) and the first pin (321). The distance between the second pin (332) and the water pipe (61) within the first pin slot (612) may be greater than the distance between the first pin (321) and the second pin (322).

[0259] The inlet of the guide tube (240) described in FIG. 7 may be aligned with the first opening (612c). The inlet of the guide tube (240) may be formed to be the same size as or larger than the first opening (612c). Alternatively, the first pin slot (612) may be positioned within the guide tube (240). For example, a guide member in which the first pin slot (612) is formed may be accommodated within the guide tube (240).

[0260] Referring to (A) of FIG. 20, the water pipe (61) may be spaced apart from the second pin (322) within the first pin slot (612). The position of the first opening through which the water pipe (61) passes may be the same as or similar to the first opening (612c) described in FIG. 19.

[0261] The above water pipe (61) may be in contact with or close to the second end (612b). In this case, referring to (B) of FIG. 20, the first door (21) may be rotated while the water pipe (61) is in contact with or close to the second end (612b).

[0262] Figure 21 is a drawing showing a second modified example of the second embodiment.

[0263] Referring to FIG. 21, the water pipe (61) of the present embodiment can pass through the first pin slot (613).

[0264] A first opening (614) through which a water pipe (61) passes may be formed at the bottom of the first pin slot (612).

[0265] In order to reduce the amount of bending of the water pipe (61) during the opening process of the first door (21), the first opening (614) may be formed in the same shape as the first pin slot (612) or may include a portion having the same shape as a part of the first pin slot (612).

[0266] The above water pipe (61) may be positioned between the first pin (321) and the second pin (322). However, in order for the water pipe (61) to be positioned between the first pin (321) and the second pin (322), a slot (310b) through which the water pipe (61) passes may be formed in the first hinge body (310a). At this time, the slot (310b) may be formed in a shape in which a part of the first hinge body (310a) is recessed between the first pin (321) and the second pin (322). Alternatively, the slot (310b) may be formed in a cut-out shape.

[0267] Alternatively, in order for the water pipe (61) to be positioned between the first pin (321) and the second pin (322), the distance between the first pin (321) and the second pin (322) in the present embodiment may be increased compared to the distance between the two pins in the first embodiment.

[0268] When the first door (21) is closed, at least a portion of the first opening (614) can overlap the second pin (322) in the vertical direction.

[0269] The inlet of the guide tube (240) described in FIG. 7 may be aligned with the first opening (614). The inlet of the guide tube (240) may be formed to be the same size as or larger than the first opening (614). Alternatively, the first pin slot (612) may be positioned within the guide tube (240). For example, a guide member in which the first pin slot (612) is formed may be accommodated within the guide tube (240).

[0270] Fig. 22 (A) is a drawing showing a third modified example of the second embodiment, and Fig. 22 (B) is a drawing showing a state in which the first door according to the third modified example of the second embodiment is opened.

[0271] Referring to Fig. 22, in the case of the third modification, unlike the second modification, a slot (310b) through which the water pipe (61) passes may be formed in the first hinge body (310a) so that the water pipe (61) is positioned between the first pin (321) and the second pin (322). The slot (310b) may be formed to penetrate between the first pin (321) and the second pin (322).

[0272] FIG. 23 is a drawing showing the shape of a water pipe inside a first door according to a third modified example of the second embodiment, where (A) of FIG. 23 shows the water pipe when the first door is closed, and (B) of FIG. 23 shows the water pipe when the first door is open.

[0273] Referring to (A) of Fig. 23, when the water pipe (61) is positioned between the first pin (321) and the second pin (322), the water pipe (61) may move horizontally during the opening process of the first door (21). If the water pipe (61) moves horizontally while being maintained in a straight shape, there is a risk that the water pipe (61) may be damaged due to an increase in the amount of bending of the water pipe (61).

[0274] In the present embodiment, in order to reduce the bending amount of the water pipe (61) during the movement of the water pipe (61), the water pipe (61) inside the first door (21) may be in a bent state when the first door (21) is closed. That is, a guide wall (241) for positioning the water pipe (61) within the first door (21) may exist, and a bent portion (61a) of the water pipe (61) may be positioned within the guide wall (241). As shown in FIG. 23 (B), during the opening process of the first door (21), the bent portion (61a) may be deformed into a straight shape or a shape similar to a straight line, that is, through a change in length, so that the bending amount of the water pipe (61) during horizontal movement may be reduced. The guide wall (241) may be a part of the guide tube (240), or may be a separate wall connected to the guide tube (240).

[0275] Fig. 24(A) is a drawing showing the position of the water pipe and the first hinge mechanism according to the third embodiment, and Fig. 24(B) is a drawing showing a modified example of Fig. 24(A).

[0276] This embodiment is identical to the first embodiment in other respects, except that there is a difference in the relative positions of the water pipe and the first hinge mechanism. Therefore, only the characteristic parts of this embodiment will be described below.

[0277] Referring to (A) of FIG. 24, the water pipe (61) of the present embodiment can pass through the first pin (321). The second pin (322) can be spaced apart from the first pin (321) and the water pipe (61). The first pin (321) can include a hole (321a), slot, or cutout for the water pipe (61) to pass through.

[0278] In order for the water pipe (61) to pass through the first pin (321), the diameter of the first pin (321) or the diameter of the water pipe (61) may be designed differently from the diameters of the water pipe and the first pin of the first embodiment.

[0279] The above water pipe (61) can pass through the first pin slot (615). A first opening (615a) through which the water pipe (61) passes can be formed in the bottom or wall of the first pin slot (615). That is, the first opening (615a) can be in communication with the first pin slot (615).

[0280] The first opening (615a) may be formed in the same shape as the first pin slot (615) or may include a portion having the same shape as a part of the first pin slot (615).

[0281] The inlet of the guide tube (240) described in FIG. 7 may be aligned with the first opening (615a). The inlet of the guide tube (240) may be formed to be the same size as or larger than the first opening (615a). Alternatively, the first pin slot (615) may be positioned within the guide tube (240). For example, a guide member in which the first pin slot (615) is formed may be accommodated within the guide tube (240).

[0282] Referring to (B) of FIG. 24, the water pipe (61) of the present embodiment can pass through the second pin (322). The first pin (321) can be spaced apart from the second pin (322) and the water pipe (61). The second pin (322) can include a hole (322a), slot, or cutout for the water pipe (61) to pass through.

[0283] In order for the water pipe (61) to pass through the second pin (322), the diameter of the second pin (322) or the diameter of the water pipe (61) may be designed differently from the diameters of the water pipe and the second pin of the first embodiment.

[0284] The above water pipe (61) can pass through the first pin slot (615). A first opening (615b) through which the water pipe (61) passes can be formed at the bottom of the first pin slot (615). The first opening (615b) can be formed in the same shape as the first pin slot (615) or can include a portion having the same shape as a part of the first pin slot (615).

[0285] The inlet of the guide tube (240) described in FIG. 7 may be aligned with the first opening (615b). The inlet of the guide tube (240) may be formed to be the same size as or larger than the first opening (615b). Alternatively, the first pin slot (615) may be positioned within the guide tube (240). For example, a guide member in which the first pin slot (615) is formed may be accommodated within the guide tube (240).

[0286] As another example, even if the first pin unit (320) includes a single pin, the water pipe (61) can pass through the single pin.

[0287] Figure 25 is a drawing showing the position of the water pipe and the first hinge mechanism according to the fourth embodiment.

[0288] This embodiment is identical to the first embodiment in other respects, except that there is a difference in the relative positions of the water pipe and the first hinge mechanism. Therefore, only the characteristic parts of this embodiment will be described below.

[0340] FIG. 31 (A) is a drawing showing the relative positions of a water pipe and a first hinge mechanism according to the sixth embodiment, and FIG. 31 (B) is a drawing showing a second hinge mechanism according to the sixth embodiment.

[0341] This embodiment is identical to the first embodiment in other respects, except that it differs in the shape of the first hinge mechanism and the position of the water pipe and the first hinge mechanism. Therefore, only the characteristic parts of this embodiment will be described below.

[0342] Referring to FIG. 31, the first hinge mechanism of the present embodiment may include a first hinge body (310) and a first pin unit. The first pin unit may include a single pin (321c).

[0343] The above first hinge body (310) may be provided with a hole (317) through which the water pipe (61) passes. The hole (317) may be positioned at a position spaced apart from the pin (321c).

[0344] In the present embodiment, the position of the pin (321c) may be the same as or similar to the position of the first pin (321) of the first embodiment. The position of the hole (317) may be the same as or similar to the position of the second pin (322) of the first embodiment.

[0345] A first opening through which the water pipe (61) passes may be formed in the first pin slot (212). The first opening of the present embodiment may be formed in a shape identical to or similar to the first opening described in (B) of FIG. 24. For example, a first opening (216f) may be formed at the bottom of the first guide member (213) forming the first pin slot (212).

[0346] Meanwhile, the second hinge mechanism (40) may have the same form as the second hinge mechanism (40) of the first embodiment, and may include a second pin unit (410) and a second pin slot (220) in which the second pin unit (410) is accommodated.

[0347] In the present embodiment, since the second hinge mechanism (40) includes a second pin unit having a plurality of pins (411, 412), the first door (21) can rotate stably while the center of rotation of the door can move.

[0348] The pin (321c) of the first pin unit can be aligned vertically with the first pin (411) of the second pin unit (410). The hole (317) can be aligned vertically with or overlapped with the second pin (412) of the second pin unit (410). Accordingly, the water pipe (61) can also be aligned vertically with or overlapped with the second pin (412).

[0349] The inlet of the guide tube (240) described in FIG. 7 may be aligned with the first opening (216f). The inlet of the guide tube (240) may be formed to be the same size as or larger than the first opening (216f). Alternatively, the first pin slot (212) may be positioned within the guide tube (240). For example, the first guide member (213) in which the first pin slot (212) is formed may be accommodated within the guide tube (240).

[0350] In the present embodiment, the structure of the first pin unit is simplified, and thus there is an advantage in that the water pipe can be introduced into the first door without interference with the first pin unit.

[0351] FIG. 32 (A) is a drawing showing the relative positions of a water pipe and a first hinge mechanism according to the seventh embodiment, and FIG. 32 (B) is a drawing showing a second hinge mechanism according to the seventh embodiment.

[0352] This embodiment is identical to the first embodiment in other respects, except that it differs in the shape of the first hinge mechanism and the position of the water pipe and the first hinge mechanism. Therefore, only the characteristic parts of this embodiment will be described below.

[0353] Referring to FIG. 32, the first hinge mechanism of the present embodiment may include a first hinge body (310) and a first pin unit. The first pin unit may include a single pin (322c).

[0354] The above first hinge body (310) may be provided with a hole (318) through which the water pipe (61) passes. The hole (318) may be positioned at a position spaced apart from the pin (322c).

[0355] In the present embodiment, the position of the pin (322c) may be the same as or similar to the position of the second pin (322) of the first embodiment. The position of the hole (318) may be the same as or similar to the position of the first pin (321) of the first embodiment.

[0356] A first opening (216g) through which the water pipe (61) passes may be formed in the first pin slot (212). The first opening (216g) of the present embodiment may be formed in a shape identical to or similar to the first opening described in (A) of FIG. 24. For example, the first opening (216g) may be formed at the bottom of the first guide member (213) forming the first pin slot (212).

[0357] Meanwhile, the second hinge mechanism (40) may have the same form as the second hinge mechanism (40) of the first embodiment, and may include a second pin unit (410) and a second pin slot (220) in which the second pin unit (410) is accommodated.

[0358] In the present embodiment, since the second hinge mechanism (40) includes a second pin unit having a plurality of pins (411, 412), the first door (21) can rotate stably while the center of rotation of the door can move.

[0359] The pin (322c) of the first pin unit can be aligned vertically with the second pin (412) of the second pin unit (410). The hole (318) can be aligned vertically with or overlapped with the first pin (411) of the second pin unit (410). Accordingly, the water pipe (61) can also be aligned vertically with or overlapped with the first pin (411).

[0360] The inlet of the guide tube (240) described in Fig. 7 can be aligned with the first opening (216g). The inlet of the guide tube (240) can be formed to be the same size as or larger than the first opening (216g). Alternatively, the first pin slot (212) can be positioned within the guide tube (240). For example, the first guide member (213) in which the first pin slot (212) is formed can be accommodated within the guide tube (240).

[0361] In the present embodiment, the structure of the first pin unit is simplified, and thus there is an advantage in that the water pipe can be introduced into the first door without interference with the first pin unit.

[0362] In the above embodiments, the water pipe is introduced into the first door in a form in which a pin slot is provided in the door and a pin unit is provided in the hinge body. However, it should be noted that, even in a case in which the pin slot is provided in the hinge body and a pin unit accommodated in the pin slot is provided in the door, the water pipe may be introduced into the first door in the same form as or in a modified form as in the above embodiments. For example, the water pipe may pass through the opening of the door within the pin slot or may pass through the opening of the door from the outside of the pin slot. In addition, the wire opening through which the wire passes may be arranged to be spaced apart from the opening through which the water pipe passes.

[0363] Fig. 33 (A) is a plan view of a refrigerator according to the eighth embodiment, Fig. 33 (B) is a drawing showing a state in which the hinge cover is removed in Fig. 33 (A), and Fig. 34 is a drawing showing the arrangement of water pipes and wires in the first door according to the eighth embodiment.

[0364] This embodiment is otherwise identical to the first embodiment, with the exception of the difference in the position of the wires. Therefore, only the distinctive features of this embodiment will be described below.

[0365] Referring to FIGS. 33 and 34, the first door (21) may include a first opening (216) through which the water pipe (61) passes.

[0366] In this embodiment, the position and shape of the first opening (216) may be the same as or similar to the position of the first opening of the first embodiment, so a detailed description thereof will be omitted.

[0367] The above wire (62) can also pass through the first opening (216). That is, in the present embodiment, the first opening (216) can be a common opening through which the water pipe (61) and the wire (62) pass together.

[0368] The above wire (62) may also extend along the upper side of the hinge body (310) together with the water pipe (61). The water pipe (61) and the wire (62) may be covered by a hinge cover (650). Therefore, when the first door (21) is closed, the exposure of the water pipe (61) and the wire (62) may be minimized.

[0369] In addition, the exposure of the water pipe (61) and wire (62) can be minimized during the opening process of the first door (21).

[0370] The first door (21) above is provided with a guide tube (240), and the water pipe (61) and the wire (62) can extend along the inside of the guide tube (240) and be connected to parts.

[0371] According to the present embodiment, the water pipe (61) and the wire (62) pass through the first opening (216) positioned adjacent to the center of rotation during the opening process of the first door (21). Therefore, there is an advantage in that the bending amount of the water pipe (61) and the wire (62) can be reduced during the opening and closing process of the first door (21).

[0372] FIG. 35 is a drawing showing a first door according to the ninth embodiment, FIG. 36 is a plan view showing the position of a wire introduced into the first door according to the ninth embodiment, and FIG. 37 is a drawing showing a state in which a wire is introduced into the first door according to the ninth embodiment.

[0373] Referring to FIGS. 35 to 37, the first door (21) of the present embodiment may include a hinge receiving portion (211a) in which a first hinge body (310) is received.

[0374] The hinge receiving portion (211a) may be formed at a position spaced downward from the upper surface (21e) of the first door (21). For example, the hinge receiving portion (211a) may be formed by recessing a portion of the rear surface of the first door (21) toward the front.

[0375] The first hinge body (310) may be provided with the first pin unit (320) described in the first embodiment. A first pin slot (212) in which the first pin unit (320) is received may be provided at the bottom of the hinge receiving portion (211a).

[0376] In this embodiment, the basic structure for rotation of the first door (21) is the same as that described in the first embodiment, so a detailed description will be omitted.

[0377] A hinge cover (650) for covering the first hinge body (310) can be accommodated in the hinge receiving portion (211a). Since the hinge receiving portion (211a) is positioned lower than the upper surface of the first door (21), the exposure of the hinge cover (650) to the outside can be minimized.

[0378] In the present embodiment, the wire (62) may extend along the inside of the hinge cover (650) toward the first door (21). The wire (62) may be positioned within the hinge receiving portion (211a). A through hole (652) for the wire (62) to pass through may be formed in the hinge cover (650). For example, the through hole (652) may be positioned on the upper side of the hinge cover (650).

[0379] Accordingly, the wire inside the hinge cover (650) can extend upward through the upper surface of the hinge cover (650).

[0380] For example, at least a portion of the through hole (652) may overlap with the first pin unit (320).

[0381] In the present embodiment, since the center of rotation of the first door (21) is positioned close to the first pin unit (320) during the opening process of the first door (21), if at least a portion of the through hole (652) overlaps with the first pin unit (320), there is an advantage in that the twisting of the wire (62) can be reduced during the opening process of the first door (21).

[0382] In the first door (21), a wire opening (211f) through which the wire (62) passes may be formed in the upper wall (211g) of the hinge receiving portion (211a). The upper wall (211g) of the hinge receiving portion (211a) may be spaced apart from the upper surface of the hinge cover (350). The wire (62) may be introduced into the first door (21) through the wire opening (211f).

[0383] At least a portion of the wire opening (211f) may overlap with the through hole (652) in the vertical direction. At least a portion of the wire opening (211f) may overlap with the first pin unit (320).

[0384] A wire (62) extending upward through a through hole (652) in the hinge cover (650) can be introduced into the first door (21) through the wire opening (211f).

[0385] Accordingly, there is an advantage in that the amount of bending of the wire (62) can be reduced when the wire (62) is introduced into the first door (21) from the upper side of the hinge cover (650).

[0386] It is to be noted that in this embodiment, the water pipe (61) may be omitted or introduced into the first door (61) by a structure or modified structure mentioned in the previous embodiments.

[0387] Fig. 38 is a plan view showing the positions of wires and water pipes introduced into the first door according to the 10th embodiment.

[0388] In the present embodiment, unlike FIG. 36, the water pipe (61) can be extended together with the wire (62). That is, the water pipe (61) can pass through the wire opening (211f) and the through hole (652).

[0389] Figure 39 is a plan view showing the positions of wires and water pipes introduced into the first door according to the 11th embodiment.

[0390] In the present embodiment, a structure in which a water pipe (61) is guided may be added to the structure of FIG. 36. A first opening (216) for the water pipe (61) to pass through may be formed at a position adjacent to the first pin slot (212) in the first door (21). That is, the wire (62) and the water pipe (61) may be guided to the first door (21) through separate openings.

[0391] FIG. 40 is a perspective view showing the position of a wire introduced into a first door according to the 12th embodiment, and FIG. 41 is a plan view showing the position of a wire introduced into a first door according to the 12th embodiment.

Alternatively, the hinge receiving portion (211a) may be formed by a portion of the rear surface of the first door (21) being sunken forward.

[0393] A first pin slot (212) may be provided at the bottom of the hinge receiving portion (211) as in the previous embodiments. The first pin unit (320) described in the previous embodiments may be accommodated in the first pin slot (212).

[0394] The hinge cover (650) of the present embodiment can cover the first hinge body (310) from which the first pin unit (320) is extended.

[0395] The wire (62) can extend along the internal space formed by the hinge cover (650).

[0396] The hinge cover (650) may be formed with a through hole (652) for the wire (62) to pass through. For example, the through hole (652) may be located on the upper side of the hinge cover (650). Accordingly, the wire (650) inside the hinge cover (650) may extend upward by penetrating the upper surface of the hinge cover (650). For example, at least a portion of the through hole (652) may overlap the first pin unit (320).

[0397] A second opening (wire opening) (218) through which the wire (62) extending to the outside of the hinge cover (650) passes may be formed in the first door (21). The second opening (218) may be located on one side of the first hinge body (310). For example, the second opening (218) may be located further from the first side (21c) of the first door (21) than the first pin unit (320).

[0398] The wire (62) passing through the through hole (652) of the hinge cover (650) is bent horizontally and extends toward the second opening (218), and can be bent from the upper side to the lower side of the second opening (218) to pass through the second opening (218).

[0399] Although not shown, when a water pipe (61) is added, the water pipe (61) may pass through the second opening (218) together with the wire (62), or may be introduced into the first door (21) by the same structure or a modified structure mentioned in the previous embodiments.
