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 or connected to the other component, but another component may also be "connected," "coupled," or "connected" between each component.
[0077] 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.
[0078] 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.
[0079] 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.
[0080] 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.
[0081] 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.
[0082] The above 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).
[0083] 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.
[0084] 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.
[0085] 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.
[0086] 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).
[0087] 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.
[0088] The first hinge mechanism (30) and the second hinge mechanism (40) can open the first door (21) as the center of rotation of the first door (21) moves.
[0089] 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 surrounding structure, such as a furniture shelf, during the opening process of the first door (21). The first door (21) can be opened at an angle of at least 90 degrees.
[0090] 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.
[0091] 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 pin slot (212) (see FIG. 3) provided in the first door (21).
[0092] 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.
[0093] 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).
[0094] 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 produced by the ice maker. The ice maker is also a component that receives water. The ice maker can receive water and produce ice using the water.
[0095] 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).
[0096] 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).
[0097] In addition, the first door (21) may be provided with a component (not shown) that operates to discharge water and / or ice. 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).
[0098] 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).
[0099] 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).
[0100] 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.
[0101] 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 water pipe opening (15) may be located at the rear side of the first hinge body (310). The water pipe (61) may extend forward after being drawn out 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).
[0102] The first door (21) may include a first pin slot (212) in which the first pin unit (320) is accommodated. The first pin slot (212) may be formed by a portion of the first door (21) being sunken. Alternatively, the first pin slot (212) may be formed in a first guide member (213) coupled to the first door (21).
[0103] 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.
[0104] The first pin slot (212) may be provided at the bottom of the hinge receiving portion (211).
[0105] 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.
[0106] The first pin (321) and the second pin (322) can extend downward from the first hinge body (310).
[0107] 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 center of rotation of the first door (21) can be moved by the shape of the first pin slot (212). The curvature of the first pin slot (212) can be continuously varied or stepwise varied.
[0108] Depending on the shape of the first pin slot (212), the rotation center of the first door (21) can move continuously or stepwise.
[0109] 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).
[0110] 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 upwards of the cabinet (10) and the first door (21) and then be bent downwards to pass through the first opening (216).
[0111] 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.
[0112] 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).
[0113] 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).
[0114] 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).
[0115] 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 of the first door (21).
[0116] As will be described later, the center of rotation of the first door (21) 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).
[0117] 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.
[0118] 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).
[0119] 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).
[0120] 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).
[0121] 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).
[0122] 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).
[0123] The above first opening (216) may include a portion positioned between the first end (212a) and the second end (212b).
[0124] 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).
[0125] 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).
[0126] The above refrigerator (1) may further include a hinge cover (350) that covers at least a portion of the first hinge body (310).
[0127] 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).
[0128] 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. Therefore, the hinge cover (350) can be called a guide that guides the water pipe (61) to extend to the first door (21).
[0129] The above first hinge body (310) may include a first bent portion (312) and a second bent portion (314) that are spaced apart.
[0130] 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 (314) may be formed on the side of the second body end located on the opposite side of the first body end.
[0131] 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).
[0132] 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).
[0133] 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).
[0134] 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.
[0135] 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.
[0136] 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).
[0137] 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.
[0138] 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).
[0139] The second opening (218) may be positioned further from the first side (21c) than the first pin slot (212).
[0140] The above refrigerator (1) may further include a guide unit (50) that guides the wire (62).
[0141] 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).
[0142] 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).
[0143] 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). Alternatively, the second guide (550) may be formed integrally with the upper wall (101).
[0144] The above wire (62) can be connected to the controller at the upper side of the cabinet (10). The wire (62) can be extended in a direction away from the first door (21) and then bent to be received in the first guide (510) at the rear side of the first guide (510).
[0145] 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).
[0146] 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.
[0147] When the first door (21) is closed, the first guide (510) may include, for example, a portion extending in a straight line. Referring to FIG. 4, the first guide (510) may extend in a straight line in the forward-backward direction. In the present embodiment, the forward-backward direction (or first direction) may be the arrangement direction of the cabinet (10) and the first door (21).
[0148] Accordingly, the wire (62) can be guided in a straight line toward the first door (21) within the first guide (510).
[0149] 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.
[0150] 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).
[0151] 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.
[0152] 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).
[0153] 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.
[0154] 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 a dispenser (23).
[0155] 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.
[0156] 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).
[0157] 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.
[0158] 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).
[0159] The hinge cover (350) may 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).
[0160] 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 first hinge body (310) coupled to the cabinet (10).
[0161] Alternatively, the above-mentioned connecting portion (355) may be directly connected to the cabinet (10).
[0162] 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).
[0163] 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).
[0164] 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.
[0165] 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.
[0166] 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.
[0167] Fig. 9 is a perspective view of a guide unit according to the first embodiment, and Fig. 10 is a plan view of a second guide according to the first embodiment.
[0168] Fig. 11 is a perspective view showing a first connecting member according to the first embodiment, and Fig. 12 is a perspective view showing a second connecting member according to the first embodiment.
[0169] Fig. 13 is a plan view of a first door according to the first embodiment, and Fig. 14 is a cross-sectional view taken along line 14-14 of Fig. 4. Fig. 15 is a plan view of a first door according to the first embodiment.
[0170] Referring to FIGS. 9 to 15, the first guide (510) may be formed in a tube shape forming a space (515) inside.
[0171] 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.
[0172] The first guide (510) may include a first portion (512). The first portion (512) may include the inlet (512a).
[0173] 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).
[0174] 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).
[0175] 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).
[0176] The above-described 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). In another aspect, the connecting portion (518) may also be described as including a first part (518a) extending from the first part (512) and a second part (518b) extending horizontally from the lower end of the first part (518a).
[0177] The size or diameter of the second part (518b) may be larger than the size or diameter of the first part (518a).
[0178] The second guide (550) may include a base (551). The second guide (550) may further include a barrier extending from the base (551).
[0179] 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 (550a) for the first guide (510) to be positioned. A passage (550b) may be formed between an end of the first barrier (552) and an end of the second barrier (553) so that the first guide (510) is positioned and can move.
[0180] 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. In this specification, the left-right direction (or second direction) is a direction intersecting the front-back direction.
[0181] 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).
[0182] The above first barrier (552) and second barrier (553) can protect the first guide (510) and reduce external exposure.
[0183] 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).
[0184] 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).
[0185] 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).
[0186] 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). The guide hole (555) may extend toward the passage (550b).
[0187] 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).
[0188] During the opening process of the first door (21), the first part (512) can move in a direction closer to the second barrier (553).
[0189] 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).
[0190] A plurality of ribs (558) may be provided on the lower side of the base (551). The plurality of ribs (558) may reduce the contact area between the base (551) and the cabinet (10). The plurality of ribs (558) may reinforce the strength of the base (551). For example, the plurality of ribs (558) may be arranged spaced apart from each other in the left and right directions.
[0191] At least a portion of the base (557) can be separated from the upper wall (101) by the plurality of ribs (558).
[0192] 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.
[0193] 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.
[0194] A coupling portion (560) for coupling the cover member (562) may be coupled to the base (551). The cover member (562) may include a protrusion (562a) for insertion into the coupling portion (560). The cover member (562) may include a plurality of protrusions (562a). 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 portion (560).
[0195] 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).
[0196] For example, the third barrier (556) may be positioned at the rear 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).
[0197] In connection with the arrangement of the above barriers, the base (551) may include a first base (551a) having a width corresponding to or similar to the gap between the first barrier (552) and the second barrier (553), and a second base (551b) having a width corresponding to or similar to the gap between the first barrier (552) and the third barrier (556).
[0198] The above refrigerator (1) may further include a connection unit for connecting the first guide (510) to the first door (21).
[0199] 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).
[0200] 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).
[0201] 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.
[0202] 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).
[0203] 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).
[0204] 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).
[0205] The second connecting member (530) may include a second body (531).
[0206] 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).
[0207] The first slot (523), the outlet (512b) of the first guide (510) and the second slot (532) can be aligned with the second opening (218) of the first door (21).
[0208] 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).
[0209] 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).
[0210] 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).
[0211] 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).
[0212] 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).
[0213] The first connecting member (520) can be mounted on the second body (531) while the first guide (510) is mounted on the second body (531).
[0214] That is, the first connecting member (520) can be mounted on the second connecting member (530) so as to cover the extension portion (518) mounted on the second connecting member (530).
[0215] For example, the connecting wall (522) may be mounted on the second body (531). In a state where the connecting wall (522) is mounted on the second body (531), the connecting wall (522) may surround the guide wall (534). That is, in a state where the connecting wall (522) is mounted on the second body (531), the guide wall (534) and the extension (518) may be positioned in a space formed by the connecting wall (522).
[0216] 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.
[0217] 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 (536). For example, a second hook (538) may be positioned between two first hooks (525).
[0218] 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).
[0219] 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.
[0220] 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.
[0221] The above hook hole (219) may include a first hook hole (219a) to which the first hook (525) is fastened, and a second hook hole (219b) to which the second hook (538) is fastened. The first hook hole (219a) and the second hook hole (219b) may be arranged at a position spaced apart from the second opening (218).
[0222] According to the present embodiment, since the first connecting member (520) and the second connecting member (530) are fixed to the first door (21) by a hook, the movement of the first connecting member (520) and the second connecting member (530) with respect to the first door (21) can be restricted during the rotation of the first door (21).
[0223] On the other hand, the first guide (510) can be rotated relative to the first door (21) by the first connecting member (520) and the second connecting member (530).
[0224] Meanwhile, the second opening (218) may be positioned spaced apart from the first opening (216).
[0225] At least a portion of the first opening (216) may be positioned closer to the front surface (21a) of the first door (21) than the second opening (218).
[0226] At least a portion of the second opening (218) may be positioned closer to the cabinet (10) than the first opening (216).
[0227] A portion of the first pin slot (212) may be positioned between the first opening (216) and the second opening (218).
[0228] Fig. 16 (A) is a plan view showing a state in which the first door according to the first embodiment is closed, and Fig. 16 (B) is a plan view showing a state in which the first door according to the first embodiment is opened by a first angle.
[0229] FIG. 17 is a plan view showing a state in which the first door according to the first embodiment is opened to a second angle, FIG. 18 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. 19 is a plan view showing a state in which the first door according to the first embodiment is opened to a maximum opening angle.
[0230] FIG. 20 is a drawing showing the movement trajectory of the center of rotation during the opening process of the first door according to the first embodiment, and FIG. 21 is a perspective view showing the first door according to the first embodiment opened to the maximum opening angle.
[0231] Referring to FIG. 5, FIG. 12 to FIG. 21, when the first door (21) is closed, the first barrier (552) can be positioned on the side of the first hinge body (310).
[0232] Based on (A) of Fig. 16, the water pipe opening (15) and the first hinge body (310) can be positioned in the area between the first barrier (552) and one side (10b) of the cabinet (10). The one side (10b) of the cabinet (10) means the side adjacent to the water pipe opening (15) among the two sides of the cabinet (10).
[0233] With the first door (21) closed, the 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 from the first guide (510) in a direction away from the front (10a) of the cabinet (10) or the first door (21). The second section (62b) may be bent from the first section (62a) and may extend in a direction closer to the front (10a) of the cabinet (10) or the first door (21). The second section (62b) may be connected to a controller provided in 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 upper side 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 the second opening (218) also moves during the opening and closing of the first door (21). For example, during the opening 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 located on the outside of the first guide (510) can compensate for the length increased during the opening of the first door (21), so that damage or disconnection of the wire (62) can be prevented.
[0237] As shown in (A) of Fig. 16, 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. 16, in the process of the first door (21) being opened or opened by the first angle, the center of rotation (C1) can move 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] As shown in Fig. 17, 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. 17, 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. 18, 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. 19, 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 opening the first door (21) to the maximum opening angle, the center of rotation (C1) can move away from the first pin (21).
[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 addition, since the portion of the wire (62) located outside the first guide (510) is located between the first barrier (552) and the second barrier (553), the external exposure of the wire (62) can be minimized.
[0251] 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.
[0252] It should be noted that the movement trajectory of the center of rotation disclosed in Fig. 20 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.
[0253] Fig. 22 is a plan view of a refrigerator according to the second embodiment, and Fig. 23 is a perspective view showing a state in which the first door of the refrigerator according to the second embodiment is opened to the maximum opening angle.
[0254] This embodiment is identical to the first embodiment in other respects, with the exception of the guide unit. Therefore, only the characteristic parts of this embodiment will be described below, and the same components as the first embodiment will be designated by the same drawing reference numerals.
[0255] Referring to FIGS. 22 and 23, the guide unit (70) of the present embodiment may include a first guide (710) that accommodates the wire (62). The guide unit (70) may further include a second guide (750) that guides the movement of the first guide (710).
[0256] The first guide (710) may include a curved portion. For example, at least a portion of the first guide may be rounded in a horizontal direction.
[0257] For example, the curved portion may be arranged to be convex in a direction away from the first opening (216) through which the water pipe (61) passes.
[0258] The above first guide (710) may also include the first and second parts described in the first embodiment. In the present embodiment, the first part may include a curved portion.
[0259] The first guide (710) may include a first end (710a) and a second end (710b). The second end (710b) is an end positioned adjacent to the first door (21), and the first end (710a) is an end positioned opposite the second end (710b).
[0260] When the first door (21) is closed, the horizontal distance between one side (10b) of the cabinet (10) and the first end (710a) may be smaller than the horizontal distance between the first side (21c) of the first door (21) and the second end (710b).
[0261] The second guide (750) may include a base (751). The second guide (750) may further include a barrier extending from the base (751).
[0262] The above barrier may include a first barrier (752) and a second barrier (753) spaced apart from the first barrier (752). The first barrier (752) and the second barrier (753) may form a space for the first guide (710) to be positioned.
[0263] The first barrier (752) may include a first part (752a). The first part (752a) may be located on the rear side of the first hinge body (310).
[0264] The first part (752a) may be arranged to overlap with at least one of the first hinge body (310) and the hinge cover (350) in the front-rear direction. The first part (752a) may be arranged to face a portion of the second barrier (753).
[0265] The first barrier (752) may further include a second part (752c). The second part (752c) may be positioned on the side of the first hinge body (310) or the hinge cover (350). The second part (752c) may be positioned closer to the first door (21) than the first part (752a). The second part (752c) may be positioned to face another part of the second barrier (753).
[0266] The horizontal distance (for example, the distance in the left-right direction) between the first part (752a) and the second barrier (753) may be greater than the horizontal distance (for example, the distance in the left-right direction) between the second part (752c) and the second barrier (753).
[0267] The above first barrier (752) may further include a connecting part (752b) connecting the first part (752a) and the second part (752c).
[0268] The first end (710a) of the first guide (710) may be positioned between the first part (752a) and the second barrier (753). A portion of the first guide (710) may be positioned between the second part (752c) and the second barrier (753).
[0269] The above base (751) may be provided with a guide hole (555). The first guide hole (555) may extend from the through hole (554) described in the first embodiment. Since the joint structure of the first guide and the base (751) is the same as in the first embodiment, a detailed description thereof will be omitted.
[0270] With the first door (21) closed, at least a portion of the first guide (710) may be positioned closer to the first barrier (753) than the guide hole (555).
[0271] With the first door (21) closed, the first end (710a) of the first guide (710) can overlap with the hinge cover (350) in the front-back direction.
[0272] The above guide unit (70) may further include a third barrier (756). The third barrier (756) may extend from the base (751). The third barrier (756) may be positioned to face the first part (752a).
[0273] In this embodiment, when the first door (21) is closed, the wire (62) may include a first section (62a) and a second section (62b) located on the outside of the first guide (710).
[0274] When the first door (21) is closed, the first section (62a) can be positioned adjacent to the first part (752a). When the first door (21) is opened, the first section (62a) can move in a direction that brings it close to the second barrier (753). When the first door (21) is opened, the length of the first section (62a) can increase and the length of the second section (62b) can decrease.
[0275] When the first door (21) is opened to the maximum opening angle, the first guide (710) may be arranged so that the entrance (712a) on the first end (710a) side faces the rear while having a curved portion. In the present embodiment, the first section (62a) adjacent to the first end (710a) side of the first guide (710) may be arranged in a straight line or in a shape similar to a straight line.
[0276] In this embodiment, when at least a first portion of the first guide (710) is entirely curved, the curvature of the curved portion can be reduced, thereby reducing bending of the wire within the curved portion.
[0277] Fig. 24 is a plan view of the first door according to the third embodiment.
[0278] This embodiment is otherwise identical to the first or second embodiment, except that the second connecting member is formed integrally with the first door, which differs in structure. Therefore, only the characteristic parts of this embodiment will be described below, and the same drawing reference numerals will be used for the same components as the first embodiment.
[0279] Referring to Fig. 24, a receiving groove (217) for receiving the connecting unit may be formed in the hinge receiving portion (211) of the first door (21). The receiving groove (217) may be formed by the bottom of the hinge receiving portion (211) being sunken.
[0280] The second opening (218) may be formed at the bottom of the receiving groove (217). The extension (518) of the first guide (510) may be positioned at the bottom of the receiving groove (217).
[0281] In the present embodiment, the second connecting member of the first embodiment may be omitted or a part of the structure of the second connecting member may be formed integrally with the first door (21).
[0282] A guide wall (219c) may be formed in the above-described receiving groove (217). The guide wall (219c) may guide the rotation of the first guide (510). The guide wall (219c) may limit the horizontal movement of the extension (518) relative to the first door (21) during the opening process of the first door (21).
[0283] The above guide wall (219c) may, for example, protrude upward from the receiving groove (217). The above guide wall (219c) may protrude at a position spaced apart from the peripheral wall of the receiving groove (217).
[0284] For example, a plurality of guide walls (219c) may be spaced apart from each other. The plurality of guide walls (219c) may be positioned facing each other or symmetrically. The plurality of guide walls (219c) may include a curved portion (219d) to enable rotation of the extension portion (518). In this case, the second opening (218) may be positioned between the plurality of guide walls (219c).
[0285] Alternatively, a single guide wall (219c) may be arranged to surround the extension (518). In this case, the guide wall (219c) may also include a curved portion (219b) to enable rotation of the extension (518).
[0286] A hook hole (219a) for fastening the first hook (525) may be provided at the bottom of the above-mentioned receiving groove (217).
[0287] The extension wall (522) of the first connecting member (520) may be seated on the bottom of the receiving groove (217). At this time, the extension wall (522) may be positioned between the guide wall (219c) and the peripheral wall of the receiving groove (217).
[0288] Even according to this embodiment, the movement of the first connecting member (520) relative to the first door (21) can be restricted during the rotation process of the first door (21).
[0289] On the other hand, the first guide (510) can be rotated relative to the first door (21) by the first connecting member (520).
[0290] FIG. 25 is a drawing showing a first door according to the fourth embodiment, FIG. 26 is a plan view showing the position of a wire introduced into the first door according to the fourth embodiment, and FIG. 27 is a drawing showing a state in which a wire is introduced into the first door according to the fourth embodiment.
[0291] Referring to FIGS. 25 to 27, the first door (21) of the present embodiment may include a hinge receiving portion (211a) in which a first hinge body (310) is received.
[0292] 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.
[0293] 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).
[0294] 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.
[0295] 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.
[0296] 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).
[0297] Accordingly, the wire inside the hinge cover (650) can extend upward through the upper surface of the hinge cover (650).
[0298] For example, at least a portion of the through hole (652) may overlap with the first pin unit (320).
[0299] In this 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).
[0300] 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).
[0301] 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).
[0302] The wire (62) extending upward through the through hole (652) in the hinge cover (650) can be introduced into the first door (21) through the wire opening (211f).
[0303] 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).
[0304] FIG. 28 is a drawing showing a first hinge mechanism and a second hinge mechanism according to a fifth embodiment.
