[0096] Figure 1 is a perspective view of a refrigerator according to the first embodiment. Figure 2 (A) is a top view of the refrigerator of the first embodiment, Figure 2 (B) is Figure 1 Magnified view of part A.

[0097] Reference Figure 1 and Figure 2 The refrigerator 1 of this embodiment can be set up in the kitchen alone, or in the form of a cabinet (or wall) housed in the room. When the refrigerator 1 is set up in the indoor cabinet, the refrigerator 1 can be set up alone or arranged side by side with other refrigerators.

[0098] The refrigerator 1 may include a housing 10 having a storage space and a door 20 for opening and closing the storage space.

[0099] Although not limiting, the storage space may be divided into a first space 11 on the upper side and a second space 12 on the lower side.

[0100] The 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 .

[0101] 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 left and right. Alternatively, the storage space may be a single space, and a single door may be used to open and close the storage space.

[0102] One or more of the first door 21 and the second door 22 may be a revolving door. Alternatively, the single door 20 may be a revolving door.

[0103] In this embodiment, the two first doors 21 are arranged on the left and right as an example. It should be noted that the following description of the "first door 21" can also be applied to doors having components for receiving or using water.

[0104] The first door 21 may be rotatably connected to the box body 10 using a first hinge mechanism 30 and a second hinge mechanism 40 .

[0105] 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.

[0106] The first hinge mechanism 30 and the second hinge mechanism 40 can open the first door 21 as the rotation center (also referred to as an imaginary rotation center) of the first door 21 moves.

[0107] When the rotation center of the first door 21 moves, the first door 21 can be prevented from interfering with the furniture cabinet during opening, and the opening angle can be increased. The first door 21 can be opened at an angle of at least 90 degrees.

[0108] 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 of the housing 10 and connected to the upper side of the first door 21. A portion of the first hinge body 310 may overlap with the upper side of the first door 21 in the upper and lower directions.

[0109] The first hinge mechanism 30 may further include a first pin unit 320 (see Figure 5The first pin unit 320 may be combined with the first hinge body 310 or formed as one piece with the first hinge body 310. The first pin unit 320 may be received in the first pin groove 212 (see FIG. Figure 3 ).

[0110] The second hinge mechanism 40 may include a second hinge body 410. The second hinge body 410 may be coupled to the front or lower side of the housing 10 and may be connected to the lower side of the first door 21. A portion of the second hinge body 410 may overlap with the lower side of the first door 21 in the vertical direction.

[0111] The second hinge mechanism 40 may further include a second pin unit 420. The second pin unit 420 may be coupled to or integrally formed with the second hinge body 410. The second pin unit 420 may be received in a second slot 220 provided in the first door 21.

[0112] The first door 21 may further include a dispenser 23. The dispenser 23 receives water and can discharge the received water. If the first door 21 additionally includes an ice maker, the dispenser 23 can also discharge ice. The ice maker also receives water and can use the received water to produce ice.

[0113] 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 by a liquid pipe for liquid flow. The ice maker may also be directly or indirectly connected to the water pipe 61.

[0114] The water pipe 61 can be led out from the inside of the box body 10 through the water pipe opening 15 to the outside and then introduced into the inside of the first door 21. Alternatively, the water pipe 61 can also be directly introduced from the outside of the box body 10 into the inside of the first door 21.

[0115] Although not shown, the first door 21 may be provided with a component that operates to drain water and / or ice. This component may be electrically connected to the wire 62. Alternatively, 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 separately from the component, and one or more of the display unit, input unit, sensor unit, and door-side control unit may be electrically connected to the wire 62.

[0116] As an example, the wire 62 can be connected to a controller provided in the box 10, and the wire 62 can be introduced into the first door 21 and connected to the component directly or indirectly (when connected to an additional wire provided inside the first door).

[0117] It should be noted that, in this specification, the water pipe 61 and / or the wire 62 are introduced into the first door 21 or the box body 10 , which can also be interpreted conversely as the water pipe 61 and / or the wire 62 being led out from the first door 21 or the box body 10 .

[0118] Figure 3 1 is a diagram showing the first hinge mechanism of the first embodiment as viewed from the rear side of the refrigerator. Figure 4 It is a plan view showing a state where the first hinge mechanism of the first embodiment is installed in a refrigerator. Figure 5 It is along Figure 3 5-5 cut-away cross-sectional view.

[0119] Reference Figures 2 to 5 The upper side wall 101 of the box body 10 may be provided with a water pipe opening 15 for the water pipe 61 to pass through. The upper side wall 101 may be provided with a guide member, which is inserted into the water pipe opening 15 and guides the water pipe 61 to pass through.

[0120] The water pipe opening 15 may be located behind the first hinge body 310. The water pipe 61 may extend forward after exiting 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.

[0121] The first door 21 may include a first pin slot 212 for accommodating the first pin unit 320. The first pin slot 212 may be formed by a recessed portion of the first door 21. Specifically, 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.

[0122] The first door 21 may include a hinge receiving portion 211 for receiving the first hinge body 310. The hinge receiving portion 211 may be formed by a portion of the top surface of the first door 21 being recessed downward. Alternatively, the hinge receiving portion 211 may be formed by a portion of the back surface of the first door 21 being recessed forward.

[0123] The first pin groove 212 may be provided on the bottom surface of the hinge accommodating portion 211 .

[0124] The first pin unit 320 may include one or more pins received in the first pin slot 212. As an example, Figure 5 The first pin unit 320 is shown as including 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. This situation can also be understood as the first pin unit 320 comprising a single pin. The single pin may be formed in a non-circular shape, but may include a curve to prevent interference with the wall forming the first pin slot 212 during the opening of the first door 21.

[0125] The first pin 321 and the second pin 322 may extend downward from the first hinge body 310 .

[0126] If the first door 21 is opened with the first pin 321 and the second pin 322 accommodated in the first pin groove 212 , the rotation center of the first door 21 can be moved by the shape of the first pin groove 212 .

[0127] The curvature of the first pin slot 212 may change continuously or in stages. According to the shape of the first pin slot 212, the rotation center may move continuously or in stages.

[0128] The first pin unit 320 may extend downward from a portion of the first hinge body 310 located above the first door 21 .

[0129] The first door 21 may include a first opening 216 for the water pipe 61 to pass through. The first opening 216 may be referred to as a door water pipe opening. The water pipe 61 may extend generally horizontally from the housing 10 to the upper side of the first door 21, then bend downward and pass through the first opening 216.

[0130] The water pipe 61 may be led out from the box body 10 right behind the first hinge mechanism 30 and then extend toward the first opening 216. Therefore, the amount of bending of the water pipe 61 can be reduced when the first door 21 is closed.

[0131] The first opening 216 may be disposed outside the first pin slot 212 . The first opening 216 may be disposed adjacent to the first pin slot 212 .

[0132] In this embodiment, since the center of rotation of the first door 21 moves, the position of the first opening 216 can change when the first door 21 rotates. Since the water pipe 61 passes through the first opening 216, the water pipe 61 can also move horizontally during the rotation of the first door 21, for example.

[0133] The size or diameter of the first opening 216 may be larger than the size or diameter of the water pipe 61 , so that the water pipe 61 can move within the first opening 216 .

[0134] If the movement amount of the water pipe 61 is reduced, the bending amount of the water pipe 61 can be reduced. In order to reduce the movement amount of the water pipe 61, the first opening 216 is preferably provided adjacent to the rotation center.

[0135] The rotation center can be moved from at least a portion of the entire open area of the first door 21 toward the first pin unit 320 , as will be described later. Therefore, in this embodiment, the first opening 216 can be disposed adjacent to the first pin unit 320 .

[0136] As an example, the first door 21 may include a first side surface 21c, which is one of two side surfaces of the first door 21 and is adjacent to the first hinge body 310. The first side surface 21c may be adjacent to the furniture cabinet.

[0137] The first pin slot 212 may extend in a curved shape and may include a first end 212a and a second end 212b. Although not limiting, the first pin slot 212 may be formed to protrude from the front face 21a of the first door 21 toward the box body 10 when viewed from the top face of the first door 21.

[0138] The first end portion 212a may be closer to the first side surface 21c than the second end portion 212b. The second end portion 212b may be closer to the front surface 21a of the first door 21 than the first end portion 212a.

[0139] When the first door 21 is closed, the first pin 321 may contact or be adjacent to the second end 212b. When the first door 21 is open at the maximum angle, the second pin 322 may contact or be adjacent to the first end 212a.

[0140] The first opening 216 may include a portion closer to the front surface 21 a of the first door 21 than the first pin unit 320 .

[0141] The first opening 216 may include a portion closer to the front surface 21 a of the first door 21 than the first pin groove 212 .

[0142] The first opening 216 may include a portion between the first end portion 212a and the second end portion 212b. That is, if a straight line connects the first end portion 212a and the second end portion 212b, the straight line may overlap the first opening 216 in the up-down direction.

[0143] The first opening 216 may include a portion closer to the box body 10 than the first end 212 a and the second end 212 b .

[0144] The first opening 216 may include a portion farther from the first side surface 21 c than the first end portion 212 a . The first opening 216 may include a portion closer to the first side surface 21 c than the second end portion 212 b .

[0145] The refrigerator 1 may further include a hinge cover 350 covering at least a portion of the first hinge body 310 .

[0146] The hinge cover 350 may cover at least a portion of the first hinge body 310 that overlaps with the first door 21. The hinge cover 350 may be disposed on the first hinge body 310 or on the first door 21.

[0147] The water pipe 61 can pass through the first opening 216 while being located in the internal space formed by the hinge cover 350. In other words, the hinge cover 350 can cover the water pipe 61 that has passed through the first opening 216. In this case, the hinge cover 350 remains covering the water pipe 61 during the opening and closing of the first door 21, thereby reducing the water pipe 61 from being exposed to the outside.

[0148] The first hinge body 310 may include a first bending portion 312 and a second bending portion 314 that are separated from each other.

[0149] Taking the closed state of the first door 21 as a reference, the first bending portion 312 can be formed on the first main body end side adjacent to the first side surface 21c in the first hinge body 310, and the second bending portion 314 can be formed on the second main body end side located on the opposite side of the first main body end.

[0150] The first bending portion 312 and the second bending portion 314 may be bent from the first hinge body 310 to protrude upward.

[0151] The first bend portion 312 and the second bend portion 314 may function as reinforcements. The first bend portion 312 and the second bend portion 314 may function as restricting portions that limit the movement of the water pipe 61. For example, the water pipe 61 may be located between the first bend portion 312 and the second bend portion 314.

[0152] The hinge cover 350 may be configured to cover both sides of the first hinge body 310. The first bending portion 312 and the second bending portion 314 may first restrict the horizontal movement of the water pipe 61. The hinge cover 350 may further restrict the horizontal movement of the water pipe 61.

[0153] The hinge cover 350 may cover the upper side of the first opening 216 to reduce exposure of the water pipe 61. As an example, the hinge cover 350 may include a portion overlapping with the first opening 216 in the upper and lower directions.

[0154] When the water pipe 61 passes through the first opening 216, the water pipe 61 may overlap the first pin unit 320 in the vertical direction. For example, the water pipe 61 may overlap the second pin 322 in the vertical direction.

[0155] The first door 21 may further include a second opening 218 (see FIG. Figure 12 The second opening 218 may be referred to as a door wire opening. The second opening 218 may also be provided in the hinge receiving portion 211 .

[0156] In this embodiment, the wire 62 may be one or more wires that are separated or bundled and pass through the first door 21. In the following description, the wires 62 are collectively referred to as "wires 62" regardless of their form.

[0157] The wire 62 may pass through the first door 21 at a position horizontally spaced apart from the first opening 216. In this embodiment, the first opening 216 may be closer to the first side surface 21c than the second opening 218.

[0158] The first pin groove 212 may be closer to the first side surface 21 c than the second opening 218 .

[0159] The refrigerator 1 may further include a guide unit 50 for guiding the conductive wire 62 .

[0160] The guide unit 50 may include a first guide 510 for receiving the wire 62. The guide unit 50 may further include a second guide 550 for guiding movement of the first guide 510.

[0161] The first guide member 510 may be connected to the first door 21. For example, one side of the first guide member 510 may be connected to the first door 21 using connection units 520 and 530. The other side of the first guide member 510 may be connected to the second guide member 550.

[0162] The second guide member 550 may be provided on the box body 10 . For example, the second guide member 550 may be provided on the upper side wall 101 of the box body 10 .

[0163] The wire 62 may be connected to the controller at the upper side of the box 10 . The wire 62 may be bent after extending toward the rear of the box and accommodated in the first guide 510 from the rear side of the first guide 510 .

[0164] The first guide member 510 can not only accommodate the wire 62 to protect the wire 62 , but also reduce exposure of the wire 62 during the opening process of the first door 21 .

[0165] When the first door 21 is closed, a portion of the first guide 510 vertically overlaps the housing 10, and another portion vertically overlaps the upper side of the first door 21. In this case, a portion of the first guide 510 may be longer than the other portion.

[0166] When the first door 21 is closed, the first guide member 510 may include a portion extending in a straight line. Figure 4 The first guide member 510 may extend in a straight line along the front-rear direction. Therefore, the wire 62 may be guided in a straight line toward the first door 21 in the first guide member 510 .

[0167] Figure 6 1 is a diagram showing the internal structure of the first door of the first embodiment, Figure 7 It is along Figure 6 7-7 is a cross-sectional view.

[0168] Reference Figure 6 and Figure 7 A guide pipe 240 may be provided inside the first door 21 to guide the water pipe 61 passing through the first opening 216. The guide pipe 240 may be connected from the side of the first opening 216 to the side of the distributor 23. The guide pipe 240 may be formed as a tube with a hollow interior. Alternatively, a guide member or bushing may be provided extending downward from the side of the first opening 216, and the guide member or bushing may also be connected to or inserted into the guide pipe 240.

[0169] A heat insulating member for heat insulation may be provided inside the first door 21. For example, the heat insulating member may be formed by injecting a foaming liquid and then solidifying the foaming liquid. The guide pipe 240 may limit the contact between the water pipe 61 and the heat insulating member.

[0170] For example, the guide tube 240 may be in contact with or connected to the bottom surface of the hinge accommodating portion 211. The size or diameter of the guide tube 240 may be larger than the size or diameter of the water tube 61. Therefore, the water tube 61 can move within the guide tube 240 during the opening and closing process of the first door 21.

[0171] Since the water pipe 61 passes through the first opening 216 in a bent state while being located at a higher position than the second pin 322 , the bending amount can be reduced by increasing the radius of the bent portion of the water pipe 61 .

[0172] The water pipe 61 guided by the guide pipe 240 can be connected to a component for regulating the flow of water in the first door 21. As an example, the component can be a valve. An additional pipe can be connected to the valve, and such a pipe can be connected to the distributor 23.

[0173] The first door 21 may further include an ice making chamber wall 250 forming an ice making chamber. An ice making machine for producing ice may be provided in the ice making chamber. In this case, a door pipe 65 may be provided inside the first door 21 to receive water from the water pipe 61 and direct the water to the ice making machine.

[0174] At least a portion of the 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.

[0175] Figure 8 (A) is a perspective view of the hinge cover of the first embodiment viewed from above. Figure 8 (B) is a perspective view of the hinge cover of the first embodiment as viewed from the bottom.

[0176] Reference Figure 5 、 Figure 7 and Figure 8 The hinge cover 350 may include a first wall 351. The first wall 351 may be located on an upper side of the hinge receiving portion 211 of the first door 21.

[0177] The hinge cover 350 may further include a second wall 352 extending downward from the first wall 351. As an example, the second wall 352 may extend from a portion of an edge of the first wall 351.

[0178] The hinge cover 350 may further include a coupling portion 355 coupled to a frame (not shown) provided on the box body 10 . The frame may cover a portion of the first hinge body 310 coupled to the box body 10 .

[0179] Alternatively, the coupling portion 355 may be directly coupled to the housing 10 .

[0180] The first wall 351 and the second wall 352 of the hinge cover 350 may form a space 353. The space 353 may accommodate a portion of the first hinge body 310 and the water pipe 61. In the space 353, the water pipe 61 may be located between the first hinge body 310 and the first wall 351.

[0181] The hinged cover 350 may include a first through hole 354 for passing the water pipe 61. As an example, the first through hole 354 may be formed in the coupling portion 355 or formed by an opening of the second wall 352.

[0182] The hinged cover 350 may further include a second through hole 356 for passing the water pipe 61. As an example, the first through hole 354 may be a side opening, and the second through hole 356 may be a bottom opening.

[0183] The first wall 351 may overlap at least a portion of the first pin unit 320 in the up-down direction. The first wall 351 may overlap the first opening 216 in the up-down direction.

[0184] When 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.

[0185] Figure 9 is a perspective view of the guide unit of the first embodiment, Figure 10 is a perspective view showing a first connecting member of the first embodiment, Figure 11 It is a perspective view showing the second connecting member of the first embodiment. Figure 12 It is along Figure 4 12-12 cut-away cross-sectional view.

[0186] Reference Figures 9 to 12 , the first guide member 510 may be formed in a tube shape with a space 515 formed therein.

[0187] The first guide member 510 may include an inlet 512a and an outlet 512b. The inlet 512a and the outlet 512b may also be used as the opposite concept.

[0188] The first guide 510 may include a first portion 512. The first portion 512 may include the inlet 512a.

[0189] The first guide member 510 may further include a second portion 514 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.

[0190] The second portion 514 may be provided with an extension portion 516. The extension portion 516 may extend horizontally from an outer surface of the second portion 514. For example, the extension portion 516 may extend from a lower end portion of the second portion 514.

[0191] The first guide member 510 may further include a coupling portion 518 for coupling with the second guide member 550. For example, the coupling portion 518 may protrude from the first portion 512. The coupling portion 518 may protrude downward from a position adjacent to the inlet 512a in the first portion 512.

[0192] The coupling portion 518 may include a first component 518 a extending from the first portion 512 and a second component 518 b extending downward from the first component 518 a .

[0193] The size or diameter of the second component 518b may be larger than the size or diameter of the first component 518a.

[0194] The second guide member 550 may include a base 551. The second guide member 550 may further include a shield extending from the base 551.

[0195] The shield may include a first shield 552 and a second shield 553 spaced apart from the first shield 552. The first shield 552 and the second shield 553 may form a space for disposing the first guide 510.

[0196] As an example, the first shielding member 552 and the second shielding member 553 may extend in the front-to-rear direction and be spaced apart in the left-to-right direction.

[0197] The first portion 512 may be provided in the space between the first shield 552 and the second shield 553. The distance between the first shield 552 and the second shield 553 may be greater than the width (for example, the left-right width) of the first portion 512.

[0198] The first shielding member 552 and the second shielding member 553 can protect the first guide member 510 and reduce the exposure of the first guide member 510 to the outside.

[0199] The base 551 may include a through hole 554 for inserting the coupling portion 518 . The base 551 may include a guide hole 555 for guiding the movement of the coupling portion 518 . The guide hole 555 may extend from the through hole 554 .

[0200] The second component 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 component 518a and smaller than the size or diameter of the second component 518b.

[0201] Therefore, during the movement of the first guide member 510 , the first component 518 a is located above the guide hole 555 and the second component 518 b is located below the base 551 , thereby preventing the first guide member 510 from being separated from the second guide member 550 .

[0202] The guide hole 555 may extend from the through hole 554 toward the first door 21. The through hole 554 may be closer to the first shielding member 552 than the second shielding member 553. The guide hole 555 may extend from the through hole 554 toward the second shielding member 553.

[0203] The guide hole 555 may intersect the first shielding member 552 and the second shielding member 553. Therefore, when the first door 21 is closed, the first portion 512 may be disposed adjacent to the first shielding member 552.

[0204] During the opening process of the first door 21 , the first portion 512 may move toward the second shielding member 553 .

[0205] The second guide member 550 may further include a fastening portion 557 for fastening to the box body 10. As an example, a plurality of fastening portions 557 may extend from the base 551.

[0206] A plurality of ribs 558 may be provided on the underside of the base 551. The ribs 558 may reduce the contact area between the base 551 and the housing 10. At least a portion of the base 551 may be separated from the upper sidewall 101 by the ribs 558. The ribs 558 may enhance the strength of the base 551.

[0207] The 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 for the wire 62. For example, the cover member 562 may be formed in a shape that is convex upward.

[0208] If the wire 62 is located between the base 551 and the cover member 562 , the upward movement of the wire 62 can be restricted.

[0209] The base 551 may be coupled to a coupling portion 560 for coupling the cover member 562. A portion of the cover member 562 may be inserted into the coupling portion 560. In this embodiment, there is no limitation on the coupling method of the cover member 562 and the coupling portion 560.

[0210] The guide unit 50 may further include a third shielding member 556. The third shielding member 556 may extend from the base 551. The third shielding member 556 may restrict horizontal movement of the bent portion (the first portion and the second portion described below) of the wire 62 located outside the first guide member 510.

[0211] As an example, the third shielding member 556 may be located on the rear side of the cover member 562. The third shielding member 556 may be spaced apart from the first shielding member 552. The distance between the third shielding member 556 and the first shielding member 552 may be greater than the distance between the first shielding member 552 and the second shielding member 553.

[0212] The refrigerator 1 may further include a connection unit for connecting the first guide 510 to the first door 21 .

[0213] The connection unit may include a first connection member 520 and a second connection member 530. The connection unit may allow the first guide 510 to be rotatably connected to the first door 21.

[0214] The connection unit may be fixed to the first door 21 , and the connection unit may guide the rotation of the first guide 510 when the first guide 510 rotates relative to the first door 21 .

[0215] The first connecting member 520 may include a first body 521. The first body 521 may include a first groove 523 for receiving a portion of the first guide 510.

[0216] The second portion 514 of the first guide member 510 may be disposed in the first slot 523. When the second portion 514 is located in the first slot 523, the second portion 514 can rotate without interfering with the first body 521. Therefore, the first slot 523 may include a curved portion, allowing the wire 62 to pass through the first slot 523.

[0217] The first connecting member 520 may include an extension wall 522 extending from the first body 521. As an example, the extension wall 522 may extend downward from a portion of an edge of the first body 521.

[0218] The first connecting member 520 may further include a first hook 525 for coupling with the first door 21. For example, a plurality of first hooks 525 may extend from the extending wall 522 in a spaced-apart manner.

[0219] The second connection member 530 may include a second body 531 .

[0220] The extension portion 518 of the first guide member 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 member 510. The second slot 532 may be aligned with the first slot 523. The wire 62 may pass through the second slot 532.

[0221] The first groove 523 and the second groove 532 may be aligned with the second opening 218 of the first door 21 .

[0222] The second connecting member 530 may further include a guide wall 534 for guiding the rotation of the extension portion 518 of the first guide member 510 disposed on the second body 531. The guide wall 534 may restrict the first guide member 510 from moving horizontally during its rotation.

[0223] As an example, the guide wall 534 may protrude from the top surface of the second body 531. The guide wall 534 may protrude at a position spaced inward from an edge of the second body 531.

[0224] As an example, the plurality of guide walls 534 may be spaced apart from each other, may be arranged to face each other or be symmetrical, and may include a curved portion 534a to enable the extension portion 518 to rotate.

[0225] Alternatively, a single guide wall 534 may be configured to surround the extension portion 518. In this case, the guide wall 534 may also include a curved portion 534a to enable the extension portion 518 to rotate.

[0226] The second connecting member 530 may further include a second hook 538 for coupling with the first door 21. For example, a plurality of second hooks 538 may extend from the second body 531 in a spaced-apart manner.

[0227] In a state in which the first guide 510 is seated on the second body 531 , the first connecting member 520 may be seated on the second body 531 .

[0228] As an example, the connecting wall 522 may be mounted on the second body 531. When the connecting wall 522 is mounted on the second body 531, the connecting wall 522 may surround the guide wall 534. In other words, when the connecting wall 522 is mounted on the second body 531, the guide wall 534 and the extension portion 518 may be located in a space formed by the connecting wall 522.

[0229] If the connecting wall 522 is disposed on the second body 531, the extending portion 518 may be located between the first body 521 and the second body 531. Therefore, the up-and-down movement of the first guide member 510 can be restricted.

[0230] A slot 536 may be formed in the second body 531 at a position corresponding to the first hook 525 to prevent interference between the first hook 525 and the second body 531. If the connecting wall 522 is disposed on the second body 531, the first hook 525 may be positioned in the slot. For example, a second hook 538 may be disposed between two first hooks 525.

[0231] The length of the first hook 525 may be greater than that of the second hook 538 , so that the first hook 525 can be fastened to the first door 21 .

[0232] The hinge receiving portion 211 of the first door 21 may be formed with a receiving groove 217 for receiving the connecting unit. The receiving groove 217 may be formed by a bottom surface of the hinge receiving portion 211 being recessed.

[0233] The bottom surface of the receiving groove 217 may be formed with a second opening 218. The bottom surface of the receiving groove 217 may be provided with a second body 531. The bottom surface of the receiving groove 217 may be provided with hook holes 219 for fastening the first hook 525 and the second hook 538 respectively.

[0234] According to this embodiment, the first and second connecting members are fixed to the first door 21 using hooks, thereby restricting the first and second connecting members 520 and 530 from moving relative to the first door 21 during the rotation of the first door 21. Conversely, the first guide 510 can rotate relative to the first door 21 using the first and second connecting members 520 and 530.

[0235] Figure 13 (A) is a top view showing a state where the first door of the first embodiment is closed, Figure 13 (B) is a plan view showing a state in which the first door of the first embodiment is opened at a first angle.

[0236] Figure 14 is a top view showing a state where the first door of the first embodiment is opened at a second angle, Figure 15 is a top view showing a state where the first door of the first embodiment is opened at a third angle, Figure 16 It is a plan view showing a state in which the first door of the first embodiment is opened to a maximum opening angle.

[0237] Figure 17 1 is a diagram showing the movement trajectory of the rotation center during the opening process of the first door of the first embodiment. Figure 18 It is a perspective view showing a state in which the first door of the first embodiment is opened to a maximum opening angle.

[0238] Reference Figure 5 、 Figures 12 to 18 With the first door 21 closed, the portion of the wire 62 located outside the first guide member 510 may include a first portion 62a and a second portion 62b bent from the first portion 62a. The first portion 62a may extend from the first guide member 510 away from the front surface 10a of the housing 10. The second portion 62b may extend from the first portion 62a toward the front surface 10a of the housing 10 after bending.

[0239] For example, the first portion 62a and the second portion 62b may be bent to protrude away from the first door 21. Alternatively, when viewed from the top surface of the box body 10, the first portion 62a and the second portion 62b may be arranged in a shape of "∩".

[0240] The second opening 218 in the first door 21 may be spaced apart from the rotation center C1 of the first door 21. Therefore, the second opening 218 may move during the opening and closing process of the first door 21.

[0241] The wire 62 running through the second opening 218 also moves during the opening and closing of the first door 21. For example, the second opening 218 moves away from the housing 10 during the opening of the first door 21, necessitating an increase in the length of the wire 62. In this embodiment, the portions (the first and second portions) located outside the first guide member 510 compensate for this increase in length during the opening of the first door 21, thereby preventing damage or disconnection of the wire 62.

[0242] like Figure 13 As shown in (A), when the first door 21 is closed, the rotation center C1 may be located at the first door 21. When the first door 21 is closed, the rotation center C1 may be closer to the front surface 21a of the first door 21 than the first opening 216 and the second opening 218.

[0243] When the first door 21 is closed, the first guide 510 may be perpendicular to the front surface 10 a of the box body 10 . Alternatively, the first guide 510 may be parallel to the side surface 10 b of the box body 10 .

[0244] like Figure 13 As shown in (B), the rotation center C1 can move in a direction away from the front surface 10a of the box body 10 when the first door 21 is opened to the first angle or during the opening process.

[0245] The first guide member 510 may move along the guide hole 555. When the first door 21 is opened at a first angle, the first guide member 510 may be tilted relative to the side surface 10b of the box body 10.

[0246] When the first door 21 is opened at a second angle, the rotation center C1 may be adjacent to the first opening 216 .

[0247] When the first door 21 is opened at a first angle, at least a portion of the second opening 218 may be further away from the box body 10 than the first opening 216 .

[0248] like Figure 14 As shown, the rotation center C1 can move toward the first pin unit 320 when the first door 21 is opened to the second angle or during the opening process. In addition, the rotation center C1 can move toward the box body 10.

[0249] like Figure 15 As shown, the rotation center C1 may move toward the first pin unit 320 when the first door 21 is opened to a third angle or during the opening process. As an example, the third angle may be 90 degrees.

[0250] When the first door 21 is opened at the third angle, the rotation center C1 may be adjacent to the first pin 321. When the first door 21 is opened at the third angle, the first opening 216 may include a portion farther from the front surface 10a of the box body 10 than the rotation center C1.

[0251] like Figure 16 As shown, if the first door 21 is opened to a maximum opening angle greater than 90 degrees, the rotation of the first door 21 may be restricted.

[0252] The rotation center C1 may move in a direction away from the first pin 321 when the first door 21 is opened to a maximum opening angle or during an opening process.

[0253] When the first door 21 is opened to its maximum angle, the first guide 510 can be located to the side of the hinge cover 350, thereby reducing exposure of the hinge cover 350. Since the water pipe 61 is located within the hinge cover 350, exposure of the water pipe 61 can be minimized when the first door 21 is open.

[0254] When the first door 21 is open to its maximum angle, a portion of the first guide member 510 can be located between the first shielding member 552 and the second shielding member 553. This minimizes exposure of the wires 62 when the first door 21 is open. Furthermore, when the first door 21 is open, the wires 62 are located within the first guide member 510, limiting access by users to the wires 62 and minimizing the risk of damage to the wires 62.

[0255] During the opening process of the first door 21 , the first opening 216 moves horizontally or moves close to the rotation center C1 , thereby reducing the bending amount of the water pipe 61 .

[0256] It should be noted that Figure 17 The movement trajectory of the rotation center shown is merely an example, and the present invention is not limited thereto, and various modifications may be made depending on the form of the pin groove and the pin unit.

Figure 20 (A) is a diagram showing a first modified example of the second embodiment, Figure 20 (B) is a diagram showing a state in which the first door is open in the first modification example of the second embodiment.

[0258] The other parts of this embodiment are the same as those of the first embodiment, but the relative positions of the water pipe and the first hinge mechanism are different. Therefore, only the characteristic parts of this embodiment will be described below.

[0259] First, refer to Figure 19 In this embodiment, the water pipe 61 can pass through the first pin groove 612. A first opening 612c for the water pipe 61 to pass through can be formed on the bottom surface of the first pin groove 612.

[0260] The first opening 612c may be formed in the same shape as the first pin groove 612, or the first opening 612c may include a portion having the same shape as a portion of the first pin groove 612 to reduce the amount of bending of the water pipe 61 during the opening of the first door 21.

[0261] The first pin slot 612 may include a first end portion 612a and a second end portion 612b. When the first door 21 is closed, the first pin 321 may be in contact with or close to the first end portion 612a. The second pin 322 may be spaced apart from the first pin 321.

[0262] The water pipe 61 may be separated from the second pin 322 in the first pin groove 612. The water pipe 61 may be separated from the second end portion 612b.

[0263] In the first pin slot 612 , the second pin 322 may be located between the water pipe 61 and the first pin 321 . In the first pin slot 612 , the distance between the second pin 322 and the water pipe 61 may be greater than the distance between the first pin 321 and the second pin 322 .

[0264] Figure 7 The inlet of the guide tube 240 described above can be aligned with the first opening 612c. The inlet of the guide tube 240 can be formed to be the same size as or larger than the first opening 612c. Alternatively, the first pin groove 612 can be located within the guide tube 240. As an example, a guide member having the first pin groove 612 can also be accommodated within the guide tube 240.

[0265] Reference Figure 20 (A), the water pipe 61 can be separated from the second pin 322 in the first pin groove 612. The position of the first opening for the water pipe 61 to pass through can be Figure 19 The first opening 612c described in FIG.

[0266] The water pipe 61 may be in contact with or close to the second end portion 612b. In this case, refer to Figure 20 (B), the first door 21 may rotate in a state where the water pipe 61 is in contact with or close to the second end portion 612b.

[0267] Figure 21 It is a diagram showing a second modified example of the second embodiment.

[0268] Reference Figure 21 , the water pipe 61 of this embodiment can pass through the first pin groove 612.

[0269] A first opening 614 through which the water supply pipe 61 passes may be formed on the bottom surface of the first pin groove 612 .

[0270] The first opening 614 may be formed in the same shape as the first pin groove 612 , or the first opening 614 may include a portion having the same shape as a portion of the first pin groove 612 to reduce the amount of bending of the water pipe 61 during the opening of the first door 21 .

[0271] The water pipe 61 may be located between the first pin 321 and the second pin 322. Furthermore, the first hinge body 310a may be formed with a groove 310b for the water pipe 61 to pass through, thereby positioning the water pipe 61 between the first pin 321 and the second pin 322. In this case, the groove 310b may be formed by a portion of the first hinge body 310a being recessed between the first pin 321 and the second pin 322. Alternatively, the groove 310b may be formed as a cutout.

[0272] Alternatively, in this embodiment, the distance between the first pin 321 and the second pin 322 may be greater than the distance between the two pins in the first embodiment, so that the water pipe 61 is provided between the first pin 321 and the second pin 322 .

[0273] When the first door 21 is closed, at least a portion of the first opening 614 may overlap with the second pin 322 in the up-down direction.

[0274] Figure 7 The inlet of the guide tube 240 described above can be aligned with the first opening 614. The inlet of the guide tube 240 can be formed to be the same size as or larger than the first opening 614. Alternatively, the first pin groove 612 can be located within the guide tube 240. As an example, a guide member having the first pin groove 612 can also be accommodated within the guide tube 240.

[0275] Figure 22 (A) is a diagram showing a third modified example of the second embodiment, Figure 22(B) is a diagram showing a state in which the first door is open in the third modification example of the second embodiment.

[0276] Reference Figure 22 Unlike the second modification, in the third modification, the first hinge body 310a may be formed with a groove 310b for the water pipe 61 to pass through, so that the water pipe 61 is disposed between the first pin 321 and the second pin 322. The groove 310b may be formed to penetrate between the first pin 321 and the second pin 322.

[0277] Figure 23 FIG. 1 is a diagram showing the configuration of the water pipe inside the first door in the third modified example of the second embodiment. Figure 23 (A) shows the water pipe in the state where the first door is closed, Figure 23 (B) shows the water pipe in a state where the first door is open.

[0278] Reference Figure 23 In the embodiment (A), when the water pipe 61 is located between the first pin 321 and the second pin 322, the water pipe 61 can move horizontally during the opening of the first door 21. If the water pipe 61 moves horizontally while maintaining a straight line, there is a risk of damage to the water pipe 61 due to increased bending of the water pipe 61.

[0279] In this embodiment, the water pipe 61 inside the first door 21 can be in a bent state when the first door 21 is closed, so as to reduce the bending amount of the water pipe 61 during the movement of the water pipe 61. That is, a guide wall 241 for arranging the water pipe 61 can be provided inside the first door 21, and a bent portion 61a of the water pipe 61 can be provided inside the guide wall 241. Figure 23 As shown in FIG. 2B , during the opening of the first door 21, the bent portion 61a deforms into a straight line or a straight-line-like shape. This change in length reduces the amount of bending of the water pipe 61 during horizontal movement. The guide wall 241 may be a portion of the guide pipe 240 or an additional wall connected to the guide pipe 240.

[0363] In the present embodiment, the second hinge mechanism 40 includes a second pin unit having a plurality of pins 411 and 412 , and thus can move the rotation center of the door while stably rotating the first door 21 .

[0364] The pin 322c of the first pin unit can be aligned in the vertical direction with the second pin 412 of the second pin unit 410. The hole 318 can be aligned or overlapped in the vertical direction with the first pin 411 of the second pin unit 410. Therefore, the water pipe 61 can also be aligned or overlapped with the first pin 411 in the vertical direction.

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 groove 212 can be located within the guide tube 240. As an example, the first guide member 213 having the first pin groove 212 can also be accommodated within the guide tube 240.

[0366] In this embodiment, the structure of the first pin unit is simplified, thereby having an advantage in that the water pipe can be introduced into the first door without interfering with the first pin unit.

[0367] In the aforementioned embodiments, the water pipe is introduced into the first door using a configuration in which the pin slot is provided in the door and the pin unit is provided in the hinge body. However, it should be noted that, even in the case in which the pin slot is provided in the hinge body and the door is provided with a pin unit that is received in the pin slot, the water pipe can be introduced into the first door in the same configuration as in the aforementioned embodiments or in a modified configuration. For example, the water pipe can be introduced into the door opening within the pin slot or outside the pin slot. Furthermore, the wire opening for the wires can be separated from the opening for the water pipe.
