Alternatively, the storage space can include a first space and a second space that are separated into left and right sides. Alternatively, the storage space can be a single space, or it can be opened and closed using a single door.

[0087] One or more of the first door 21 and the second door 22 may be a revolving door. Alternatively, a single door 20 may be a revolving door.

[0088] In this embodiment, the following description uses a configuration of two first doors 21 arranged on the left and right as an example. It should be noted that the following description of the "first door 21" can be applied to doors with components that receive or use water.

[0089] The first door 21 can be rotatably connected to the housing 10 using a first hinge mechanism 30 and a second hinge mechanism 40.

[0090] The first hinge mechanism 30 can be connected to the upper side of the first door 21. The second hinge mechanism 40 can be connected to the lower side of the first door 21. The first hinge mechanism 30 can be referred to as the upper hinge mechanism. The second hinge mechanism 40 can be referred to as the lower hinge mechanism.

[0091] The first hinge mechanism 30 and the second hinge mechanism 40 can open the first door 21 as the rotation center of the first door 21 moves.

[0092] With the rotation center of the first door 21 moving, interference between the first door 21 and surrounding furniture cabinets can be prevented during the opening process, and the opening angle can be increased. The first door 21 can open to an angle of at least 90 degrees.

[0093] The first hinge mechanism 30 may include a first hinge body 310. The first hinge body 310 may be attached 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 vertical direction.

[0094] The first hinge mechanism 30 may further include a first pin unit 320 (see reference). Figure 5 The first pin unit 320 can be combined with or integrally formed with the first hinge body 310. The first pin unit 320 can be accommodated in the first pin groove 212 provided in the first door 21 (see reference). Figure 3 ).

[0096] The second hinge mechanism 40 may further include a second pin unit 420. The second pin unit 420 may be combined with or integrally formed with the second hinge body 410. The second pin unit 420 may be accommodated in a second groove 220 provided in the first door 21.

[0097] The first door 21 may also include a distributor 23. The distributor 23 is a component that receives water. The distributor 23 can discharge the received water. If the first door 21 is further equipped with an ice maker, the distributor 23 can also discharge ice generated by the ice maker. The ice maker is also a component that receives water. The ice maker can receive water and then use it to generate ice.

[0098] To discharge water, the distributor 23 can be connected directly or indirectly to the water pipe 61. If the distributor 23 is configured to discharge other liquids besides water, the water pipe 61 can be replaced by a liquid pipe for supplying liquid flow. The ice maker can also be connected directly or indirectly to the water pipe 61.

[0099] The water pipe 61 can be led out from inside the housing 10 through the water pipe opening 15 and then introduced into the first door 21. Alternatively, the water pipe 61 can also be introduced directly from outside the housing 10 into the first door 21.

[0100] Additionally, the first door 21 may be provided with a component (not shown) for discharging water and / or ice. This component may be electrically connected to the wire 62. Alternatively, the first door 21 may be separate from the component and include one or more of a display unit, an input unit, a sensor unit, and a door-side control unit, all of which may be electrically connected to the wire 62.

[0101] As an example, the wire 62 can be connected to a controller disposed in the housing 10, and the wire 62 can be introduced into the first door 21 and connected directly or indirectly (in the case of connecting with an additional wire disposed inside the first door) to the component.

[0102] 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 10, which can also be interpreted as the water pipe 61 and / or the wire 62 being led out from the first door 21 or the box 10.

[0103] Figure 3 This is a diagram showing the first hinge mechanism of the first embodiment as viewed from the rear of the refrigerator. Figure 4 This is a top view showing the state in which the first hinge mechanism of the first embodiment is installed in the refrigerator. Figure 5 It is along Figure 3 5-5 is a sectional view cut open.

[0104] Reference Figures 2 to 5 A water pipe opening 15 for the water pipe 61 to pass through may be provided on the upper side wall 101 of the housing 10. The water pipe opening 15 may be located on the rear side of the first hinge body 310. The water pipe 61 may extend forward after being led out from the water pipe opening 15. As an example, the water pipe 61 may extend along the upper side of the first hinge body 310 and pass through the first door 21.

[0105] The first door 21 may include a first pin groove 212 for receiving the first pin unit 320. The first pin groove 212 may be formed as a portion of the first door 21 is recessed. Alternatively, the first pin groove 212 may be formed in a first guide member 213 that engages with the first door 21.

[0106] The first door 21 may include a hinge receiving portion 211 for accommodating 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 recessed downwards. Alternatively, the hinge receiving portion 211 may be formed by a portion of the back surface of the first door 21 recessed forwards.

[0107] The first pin groove 212 may be provided on the bottom surface of the hinge receiving part 211.

[0108] The first pin unit 320 may include one or more pins accommodated in the first pin groove 212. As an example, Figure 5 The diagram shows that the first pin unit 320 includes a first pin 321 and a second pin 322 spaced apart from each other. Alternatively, the first pin 321 and the second pin 322 may be connected by a connecting member. This can also be understood as the first pin unit 320 comprising a single pin.

[0109] The first pin 321 and the second pin 322 can extend downward from the first hinge body 310.

[0110] 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 utilizing the shape of the first pin groove 212. The curvature of the first pin groove 212 can change continuously or in stages.

[0111] Depending on the shape of the first pin groove 212, the rotation center of the first door 21 can move continuously or in stages.

[0112] The first pin unit 320 can extend downward from the portion of the first hinge body 310 located on the upper side of the first door 21.

[0113] The first door 21 may include a first opening 216 for the water pipe 61 to pass through. The first opening 216 may be named the door water pipe opening. The water pipe 61 may extend generally horizontally along the upper side of the housing 10 and the first door 21 and then bend downwards through the first opening 216.

[0114] The water pipe 61 can extend from the housing 10 directly behind the first hinge mechanism 30 and then extend towards the first opening 216. Therefore, the amount of bending of the water pipe 61 when the first door 21 is closed can be reduced.

[0115] The first opening 216 may be configured on the outside of the first pin groove 212. The first opening 216 may be configured at a position adjacent to the first pin groove 212.

[0116] In this embodiment, since the rotation center 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, for example, the water pipe 61 can move horizontally during the rotation of the first door 21.

[0117] 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.

[0118] Reducing the amount of movement of the water pipe 61 can reduce the amount of bending of the water pipe 61. In order to reduce the amount of movement of the water pipe 61, the first opening 216 is preferably arranged adjacent to the rotation center of the first door 21.

[0119] The rotation center of the first door 21 can move from at least a portion of the overall open area of ​​the first door 21 toward the first pin unit 320, as will be explained later. Therefore, in this embodiment, the first opening 216 can be configured adjacent to the first pin unit 320.

[0120] As an example, the first door 21 may include a first side surface 21c, which is the side of the first door 21 that is adjacent to the first hinge body 310. The first side surface 21c may be adjacent to the furniture cabinet.

[0121] The first pin groove 212 may extend in a curved shape and may include a first end 212a and a second end 212b. Although not limited, the first pin groove 212 may be formed to protrude from the front 21a of the first door 21 toward the housing 10 when viewed from the top surface of the first door 21.

[0122] The first end 212a may be closer to the first side 21c than the second end 212b. The second end 212b may be closer to the front 21a of the first door 21 than the first end 212a.

[0123] 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 its maximum angle, the second pin 322 may contact or be adjacent to the first end 212a.

[0124] The first opening 216 may include a portion that is closer to the front 21a of the first door 21 than the first pin unit 320.

[0125] The first opening 216 may include a portion that is closer to the front 21a of the first door 21 than the first pin slot 212.

[0126] The first opening 216 may include a portion located between the first end 212a and the second end 212b.

[0127] The first opening 216 may include a portion that is closer to the housing 10 than the first end 212a and the second end 212b.

[0128] The first opening 216 may include a portion that is further away from the first side 21c than the first end 212a. The first opening 216 may also include a portion that is closer to the first side 21c than the second end 212b.

[0129] The refrigerator 1 may also include a hinge cover 350 that covers at least a portion of the first hinge body 310.

[0130] The hinge cover 350 can cover at least the portion of the first hinge body 310 that overlaps with the first door 21. The hinge cover 350 can be installed on the first hinge body 310 or on the first door 21.

[0131] The water pipe 61 can pass through the first opening 216 while located within the internal space formed by the hinge cover 350. That is, the hinge cover 350 can cover the water pipe 61 passing through the first opening 216. In this case, by maintaining the hinge cover 350 covering the water pipe 61 during the opening and closing of the first door 21, the exposure of the water pipe 61 to the outside can be reduced. Therefore, the hinge cover 350 can be described as a guide for guiding the water pipe 61 towards the first door 21.

[0132] The first hinge body 310 may include a first bend 312 and a second bend 314 that are spaced apart.

[0133] With the first door 21 closed as a reference, the first bending portion 312 may be formed on the first body end side adjacent to the first side 21c in the first hinge body 310, and the second bending portion 314 may be formed on the second body end side located on the opposite side of the first body end.

[0134] The first bending portion 312 and the second bending portion 314 can be bent from the first hinge body 310 to protrude upward.

[0135] The first bend 312 and the second bend 314 can serve as reinforcing parts. The first bend 312 and the second bend 314 can also serve as limiting parts that restrict the positional movement of the water pipe 61. For example, the water pipe 61 can be located between the first bend 312 and the second bend 314.

[0136] The hinge cover 350 can be configured to cover both sides of the first hinge body 310. The first bend 312 and the second bend 314 can initially restrict the horizontal movement of the water pipe 61. The hinge cover 350 can further restrict the horizontal movement of the water pipe 61.

[0137] The hinge cover 350 can cover the upper side of the first opening 216 to reduce the exposure of the water pipe 61. As an example, the hinge cover 350 may include a portion that overlaps with the first opening 216 in the vertical direction.

[0138] With the water pipe 61 passing through the first opening 216, the water pipe 61 can overlap with the first pin unit 320 in the vertical direction. As an example, the water pipe 61 can overlap with the second pin 322 in the vertical direction.

[0139] The first door 21 may also include a second opening 218 for the wire 62 to pass through (see reference). Figure 14 The second opening 218 may be referred to as a door guide opening. The second opening 218 may also be provided in the hinge receiving portion 211.

[0140] In this embodiment, the wire 62 may be one or more wires that pass through the first gate 21 in a separate or bundled manner. Hereinafter, they will be collectively referred to as "wire 62" without distinguishing their form.

[0141] The wire 62 can pass through the first door 21 at a position horizontally spaced from the first opening 216. In this embodiment, the first opening 216 can be closer to the first side 21c than the second opening 218.

[0142] The second opening 218 may be further away from the first side 21c than the first pin groove 212.

[0143] The refrigerator 1 may also include a guide unit 50 for guiding the wire 62.

[0144] The guiding unit 50 may include a first guide 510 that accommodates the wire 62. The guiding unit 50 may also include a second guide 550 that guides the movement of the first guide 510.

[0145] The first guide 510 can be connected to the first door 21. As an example, one side of the first guide 510 can be connected to the first door 21 via connecting units 520 and 530. The other side of the first guide 510 can be connected to the second guide 550.

[0146] The second guide 550 may be disposed on the housing 10. As an example, the second guide 550 may be disposed on the upper side wall 101 of the housing 10. Alternatively, the second guide 550 may be integrally formed with the upper side wall 101.

[0147] The wire 62 can be connected to the controller on the upper side of the housing 10. The wire 62 can be extended away from the first door 21 and then bent to be received into the first guide 510 from the rear side.

[0148] The first guide 510 can not only accommodate the wire 62 to protect the wire 62, but also reduce the exposure of the wire 62 during the opening of the first door 21.

[0149] With the first door 21 closed, a portion of the first guide 510 overlaps with the housing 10 in the vertical direction, and another portion overlaps with the upper side of the first door 21 in the vertical direction. In this case, the length of one portion of the first guide 510 can be greater than the length of the other portion.

[0150] With the first door 21 closed, for example, the first guide 510 may include a portion extending in a straight line. (See reference...) Figure 4 The first guide member 510 can extend in a straight line along the front-back direction. In this embodiment, the front-back direction (or the first direction) can be the arrangement direction of the housing 10 and the first door 21.

[0151] Therefore, within the first guide 510, the wire 62 can be led in a straight line toward the first door 21.

[0152] Figure 6 This is a diagram showing the internal structure of the first door in the first embodiment. Figure 7 It is along Figure 6 7-7 is a sectional view cut open.

[0153] Reference Figure 6 and Figure 7 Inside the first door 21, a guide tube 240 can be provided to guide the water pipe 61 that passes through the first opening 216. The guide tube 240 can be connected from the first opening 216 side to the distributor 23 side. The guide tube 240 can be formed into a hollow tube shape. Alternatively, a guide member or bushing extending downward from the first opening 216 side can be provided, and the guide member or bushing can also be connected to or inserted into the guide tube 240.

[0154] A heat insulation component can be installed inside the first door 21. For example, the heat insulation component can be formed by injecting and curing a foaming liquid. The guide pipe 240 can restrict contact between the water pipe 61 and the heat insulation component.

[0155] As an example, the guide tube 240 may contact or connect with the bottom surface 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, the water pipe 61 may move within the guide tube 240 during the opening and closing of the first door 21.

[0156] Since the water pipe 61 passes through the first opening 216 in a bent state while it is in a position higher than the second pin 322, the amount of bending can be reduced by increasing the radius of the bent portion of the water pipe 61.

[0157] The water pipe 61, guided by the guide pipe 240, can be connected to a component that regulates the flow of water within the first gate 21; for example, this component could be a valve. An additional pipe can be connected to the valve, such a pipe being connected to the distributor 23.

[0158] The first door 21 may also include an ice-making chamber wall 250 forming an ice-making chamber. An ice maker for producing ice may be installed in the ice-making chamber. In this case, a door pipe 65 may be installed inside the first door 21, which, after receiving water from the water pipe 61, directs the water to the ice maker.

[0159] At least a portion of the wire 62 can be guided by the guide tube 240. Alternatively, a guide tube for guiding the wire 62 can be additionally provided inside the first door 21.

[0160] 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 viewed from below.

[0161] 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 the upper side of the hinge receiving portion 211 of the first door 21.

[0162] The hinge cover 350 may 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 the edge of the first wall 351.

[0163] The hinge cover 350 may further include a connecting portion 355, which connects to a frame (not shown) disposed on the housing 10. The frame may cover a portion of the first hinge body 310 connected to the housing 10.

[0164] Alternatively, the connecting part 355 can also be directly connected to the housing 10.

[0165] The first wall 351 and the second wall 352 of the hinge cover 350 can form a space 353. A portion of the first hinge body 310 and the water pipe 61 can be accommodated in the space 353. The water pipe 61 can be located between the first hinge body 310 and the first wall 351 within the space 353.

[0166] The hinge cover 350 may include a first through hole 354 for the water pipe 61 to pass through. As an example, the first through hole 354 may be formed in the joint 355 or formed by opening in the second wall 352.

[0167] The hinge cover 350 may also include a second through hole 356 for the water pipe 61 to pass through. As an example, the first through hole 354 may be a side opening, and the second through hole 356 may be a bottom opening.

[0168] 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.

[0169] With the hinge cover 350 covering the first hinge body 310, the second wall 352 can cover the first bend 312 and the second bend 314 from the side.

[0170] Figure 9 This is a perspective view of the guiding unit of the first embodiment. Figure 10 This is a top view of the second guide member in the first embodiment.

[0171] Figure 11 This is a perspective view showing the first connecting member of the first embodiment. Figure 12 This is a perspective view showing the second connecting member of the first embodiment.

[0172] Figure 13 This is a top view of the first door in the first embodiment. Figure 14 It is along Figure 4 Sectional view cut from 14-14. Figure 15 This is a top view of the first door in the first embodiment.

[0173] Reference Figures 9 to 15 The first guide 510 can be formed as a tube with an internal space 515.

[0174] The first guide 510 may include an inlet 512a and an outlet 512b. The inlet 512a and outlet 512b may also be used as opposite concepts.

[0175] The first guide 510 may include a first portion 512. The first portion 512 may include the inlet 512a.

[0176] The first guide 510 may further include a second portion 514 that bends 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.

[0177] An extension 516 may be provided in the second portion 514. The extension 516 may extend horizontally from the outer surface of the second portion 514. As an example, the extension 516 may extend from the lower end of the second portion 514.

[0178] The first guide 510 may further include a coupling portion 518 for engaging with the second guide 550. As an example, the coupling portion 518 may protrude from the first portion 512. The coupling portion 518 may protrude downward from a position in the first portion 512 adjacent to the inlet 512a.

[0179] The joint 518 may include a first component 518a extending from the first portion 512 and a second component 518b extending downward from the first component 518a. Alternatively, the joint 518 may be described as including a first component 518a extending from the first portion 512 and a second component 518b extending horizontally from the lower end of the first component 518a.

[0180] The size or diameter of the second component 518b may be larger than the size or diameter of the first component 518a.

[0181] The second guide 550 may include a base 551. The second guide 550 may also include a shield extending from the base 551.

[0182] The shielding element may include a first shielding element 552 and a second shielding element 553 spaced apart from the first shielding element 552. The first shielding element 552 and the second shielding element 553 may form a space 550a for mounting the first guide 510. A passage 550b may be formed between the end of the first shielding element 552 and the end of the second shielding element 553, the passage 550b allowing the first guide 510 to be mounted and moved.

[0183] As an example, the first shielding member 552 and the second shielding member 553 may extend in the front-back direction and be spaced apart in the left-right direction. The left-right direction (or second direction) mentioned in this specification is a direction that intersects with the front-back direction.

[0184] The first portion 512 may be disposed in the space between the first shielding member 552 and the second shielding member 553. The distance between the first shielding member 552 and the second shielding member 553 may be greater than the width of the first portion 512 (for example, the left and right width).

[0185] The first shield 552 and the second shield 553 can protect the first guide 510 and reduce the exposure of the first guide 510 to the outside.

[0186] The base 551 may include a through hole 554 for insertion of the coupling portion 518. The base 551 may include a guide hole 555 for guiding movement of the coupling portion 518. The guide hole 555 may extend from the through hole 554.

[0187] The second component 518b can pass through the through hole 554. The width of the guide hole 555 can be smaller than the width or diameter of the through hole 554. The width of the guide hole 555 can be larger than the size or diameter of the first component 518a and smaller than the size or diameter of the second component 518b.

[0188] Therefore, during the movement of the first guide 510, the first component 518a is located above the guide hole 555, and the second component 518b is located below the base 551, thereby preventing the first guide 510 from separating from the second guide 550.

[0189] The guide hole 555 can extend from the through hole 554 toward the first door 21. The through hole 554 can be closer to the first shield 552 than the second shield 553. The guide hole 555 can extend from the through hole 554 toward the second shield 553. The guide hole 555 can extend toward the passage 550b.

[0190] The guide hole 555 can intersect with the first shield 552 and the second shield 553 respectively. Therefore, when the first door 21 is closed, the first part 512 can be arranged adjacent to the first shield 552.

[0191] During the opening of the first door 21, the first part 512 can move toward the second shield 553.

[0192] The second guide 550 may also include a fastening portion 557 for securing to the housing 10. As an example, a plurality of fastening portions 557 may extend from the base 551.

[0193] A plurality of ribs 558 may be provided on the lower side of the base 551. The plurality of ribs 558 can reduce the contact area between the base 551 and the housing 10. The plurality of ribs 558 can enhance the strength of the base 551. As an example, the plurality of ribs 558 may be spaced apart in the left-right direction.

[0194] At least a portion of the base 551 may be separated from the upper sidewall 101 by a plurality of the ribs 558.

[0195] 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 to be disposed. As an example, the cover member 562 may be configured to protrude upwards.

[0196] 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.

[0197] The base 551 may be fitted with a connecting portion 560 for engaging the cover member 562. The cover member 562 may include protrusions 562a for insertion into the connecting portion 560. The cover member 562 may include a plurality of protrusions 562a. In this embodiment, there is no limitation on the way the cover member 562 engages with the connecting portion 560.

[0198] The guiding unit 50 may further include a third shield 556. The third shield 556 may extend from the base 551. The third shield 556 may restrict the horizontal movement of the bend of the wire 62 located outside the first guide 510 (the first and second portions described later).

[0199] As an example, the third shielding member 556 may be located behind the cover member 562. The third shielding member 556 may be spaced apart from the first shielding member 552. The interval between the third shielding member 556 and the first shielding member 552 may be greater than the interval between the first shielding member 552 and the second shielding member 553.

[0200] In association with the configuration of the plurality of shielding elements, the base 551 may include: a first base 551a having a width corresponding to or similar to the spacing between the first shielding element 552 and the second shielding element 553; and a second base 551b having a width corresponding to or similar to the spacing between the first shielding element 552 and the third shielding element 556.

[0201] The refrigerator 1 may also include a connection unit for connecting the first guide 510 to the first door 21.

[0202] The connecting unit may include a first connecting member 520 and a second connecting member 530. The connecting unit allows the first guide 510 to be rotatably connected to the first door 21.

[0203] The connecting unit can be fixed to the first door 21, and the connecting unit can guide the rotation of the first guide 510 when the first guide 510 rotates relative to the first door 21.

[0204] The first connecting member 520 may include a first body 521. The first body 521 may include a first groove 523 that receives a portion of the first guide 510.

[0205] A second portion 514 of the first guide 510 may be disposed in the first groove 523. With the second portion 514 located in the first groove 523, the second portion 514 can rotate without interfering with the first body 521. Therefore, the first groove 523 may include a curved portion. The wire 62 can pass through the first groove 523.

[0206] 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 the edge of the first body 521.

[0207] The first connecting member 520 may further include a first hook 525 for engaging with the first door 21. As an example, a plurality of first hooks 525 may extend from the extension wall 522 in a spaced-out manner.

[0208] The second connecting member 530 may include a second body 531.

[0209] An extension 518 of the first guide 510 may be disposed in the second body 531. The second body 531 may include a second groove 532. The second groove 532 may be aligned with the outlet 512b of the first guide 510. The second groove 532 may be aligned with the first groove 523. The wire 62 may pass through the second groove 532.

[0210] The first groove 523, the outlet 512b of the first guide 510 and the second groove 532 can be aligned with the second opening 218 of the first door 21.

[0211] The second connecting member 530 may further include a guide wall 534 for guiding the rotation of the extension 518 of the first guide member 510 disposed in the second body 531. The guide wall 534 may restrict the horizontal movement of the first guide member 510 during rotation.

[0212] 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 the edge of the second body 531.

[0213] As an example, a plurality of guide walls 534 may be spaced apart. The plurality of guide walls 534 may be configured to face each other or be symmetrical. The plurality of guide walls 534 may include curved portions 534a to allow the extension 518 to rotate.

[0214] Alternatively, a single guide wall 534 may be configured to surround the extension 518. In this case, the guide wall 534 may also include a curved portion 534a to allow the extension 518 to rotate.

[0215] The second connecting member 530 may further include a second hook 538 for engaging with the first door 21. As an example, a plurality of second hooks 538 may extend from the second body 531 in a spaced-out manner.

[0216] With the first guide 510 placed on the second body 531, the first connecting member 520 can be placed on the second body 531.

[0217] That is, the first connecting member 520 can be disposed on the second connecting member 530 to cover the extension 518 disposed on the second connecting member 530.

[0218] As an example, the connecting wall 522 can be disposed on the second body 531. With the connecting wall 522 disposed on the second body 531, the connecting wall 522 can surround the guide wall 534. That is, with the connecting wall 522 disposed on the second body 531, the guide wall 534 and the extension 518 can be located in the space formed by the connecting wall 522.

[0219] If the connecting wall 522 is disposed on the second body 531, the extension 518 can be located between the first body 521 and the second body 531. Therefore, the vertical movement of the first guide 510 can be restricted.

[0220] A groove 536 may be formed in the second body 531 at the position corresponding to the first hook 525 to prevent the first hook 525 from interfering with the second body 531. If the connecting wall 522 is disposed in the second body 531, the first hook 525 may be located in the groove 536. As an example, a second hook 538 may be provided between the two first hooks 525.

[0221] The length of the first hook 525 can be greater than the length of the second hook 538, so that the first hook 525 can be fastened to the first door 21.

[0222] The hinge receiving portion 211 in the first door 21 may be formed with a receiving groove 217 for accommodating the connecting unit. The receiving groove 217 may be formed by a recess in the bottom surface of the hinge receiving portion 211.

[0223] The second opening 218 may be formed on the bottom surface of the receiving groove 217. The second body 531 may be placed on the bottom surface of the receiving groove 217. Hook holes 219 may be provided on the bottom surface of the receiving groove 217 for fastening the first hook 525 and the second hook 538 respectively.

[0224] The hook hole 219 may include a first hook hole 219a for securing the first hook 525 and a second hook hole 219b for securing the second hook 538. The first hook hole 219a and the second hook hole 219b may be configured at a position spaced apart from the second opening 218.

[0225] According to this embodiment, the first connecting member 520 and the second connecting member 530 are fixed to the first door 21 by hooks, thus restricting the movement of the first connecting member 520 and the second connecting member 530 relative to the first door 21 during the rotation of the first door 21.

[0226] Conversely, the first guide 510 can be rotated relative to the first door 21 using the first connecting member 520 and the second connecting member 530.

[0227] On the other hand, the second opening 218 can be configured to be spaced apart from the first opening 216.

[0228] At least a portion of the first opening 216 may be closer to the front 21a of the first door 21 than the second opening 218.

[0229] At least a portion of the second opening 218 may be closer to the housing 10 than the first opening 216.

[0230] A portion of the first pin groove 212 may be provided between the first opening 216 and the second opening 218.

[0231] Figure 16 (A) is a top view showing the first door of the first embodiment in a closed state. Figure 16 (B) is a top view showing the state of the first door of the first embodiment open at a first angle.

[0232] Figure 17 This is a top view showing the first door of the first embodiment open at a second angle. Figure 18 This is a top view showing the first door of the first embodiment open at a third angle. Figure 19 This is a top view showing the state of the first door in the first embodiment at its maximum opening angle.

[0233] Figure 20 This is a diagram illustrating the movement trajectory of the center of rotation during the opening process of the first door in the first embodiment. Figure 21 This is a perspective view showing the state of the first door in the first embodiment at its maximum opening angle.

[0234] Reference Figure 5 , Figures 12 to 21 When the first door 21 is closed, the first shield 552 can be located on the side of the first hinge body 310.

[0235] by Figure 16 Based on (A), the water pipe opening 15 and the first hinge body 310 may be provided in the area between the first shield 552 and one side 10b of the housing 10. The side 10b of the housing 10 refers to the side of the two sides of the housing 10 that is adjacent to the water pipe opening 15.

[0236] With the first door 21 closed, the portion of the wire 62 located outside the first guide 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 510 toward the front 10a of the housing 10 or the first door 21. The second portion 62b may be bent from the first portion 62a and extend toward the front 10a of the housing 10 or the first door 21. The second portion 62b may be connected to a controller disposed on the housing 10.

[0237] As an example, the first portion 62a and the second portion 62b can be bent to protrude in a direction away from the first door 21. Alternatively, when viewed from the top of the housing 10, the first portion 62a and the second portion 62b can be configured in a shape resembling a "∩".

[0238] The second opening 218 in the first door 21 can be separated from the rotation center C1 of the first door 21. Therefore, the second opening 218 can move during the opening and closing of the first door 21.

[0239] The wire 62 passing 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, thus requiring an increase in the length of the wire 62. In this embodiment, the portion located outside the first guide 510 compensates for the increased length during the opening of the first door 21, thus preventing damage or breakage of the wire 62.

[0240] like Figure 16 As shown in (A), when the first door 21 is closed, the rotation center C1 can be located at the first door 21. When the first door 21 is closed, the rotation center C1 can be closer to the front 21a of the first door 21 than the first opening 216 and the second opening 218.

[0241] With the first door 21 closed, the first guide 510 can be perpendicular to the front 10a of the housing 10. Alternatively, the first guide 510 can be parallel to the side 10b of the housing 10.

[0242] like Figure 16 As shown in (B), the rotation center C1 can move away from the front 10a of the box 10 during the opening of the first door 21 at a first angle or during the opening process.

[0243] The first guide 510 can move along the guide hole 555. When the first door 21 is open at a first angle, the first guide 510 can be tilted relative to the side 10b of the housing 10.

[0244] like Figure 17 As shown, when the first door 21 is open at the second angle, the rotation center C1 can be adjacent to the first opening 216.

[0245] With the first door 21 open at a first angle, at least a portion of the second opening 218 can be further away from the housing 10 than the first opening 216.

[0246] like Figure 17As shown, the rotation center C1 can move towards the first pin unit 320 during the opening of the first door 21 at a second angle or during the opening process. Additionally, the rotation center C1 can move towards the housing 10.

[0247] like Figure 18 As shown, the rotation center C1 can move towards the first pin unit 320 during the opening of the first door 21 at a third angle. For example, the third angle can be 90 degrees.

[0248] With the first door 21 open at a third angle, the rotation center C1 may be adjacent to the first pin 321. With the first door 21 open at a third angle, the first opening 216 may include a portion of the front surface 10a of the housing 10 that is further away from the rotation center C1.

[0249] like Figure 19 As shown, if the first door 21 opens to a maximum opening angle of 90 degrees, the rotation of the first door 21 can be restricted.

[0250] The rotation center C1 can move away from the first pin 321 as the first door 21 opens to its maximum opening angle.

[0251] With the first door 21 open at its maximum angle, the first guide 510 can be positioned to the side of the hinge cover 350, thereby reducing the exposure of the hinge cover 350. Since the water pipe 61 is located inside the hinge cover 350, the exposure of the water pipe 61 can be minimized when the first door 21 is open.

[0252] With the first door 21 open at its maximum angle, a portion of the first guide 510 can be positioned between the first shield 552 and the second shield 553. This minimizes the exposure of the wire 62 when the first door 21 is open. Furthermore, with the first door 21 open, the wire 62 is located within the first guide 510, thus restricting user access to the wire 62 and minimizing the risk of damage to it.

[0253] In addition, the portion of the conductor 62 located outside the first guide 510 is situated between the first shield 552 and the second shield 553, thus minimizing the external exposure of the conductor 62.

[0254] During the opening of the first door 21, the first opening 216 moves horizontally or moves closer to the rotation center C1, thereby reducing the amount of bending of the water pipe 61.

[0255] It should be noted that, Figure 20 The trajectory of the rotation center shown is illustrative, and the present invention is not limited thereto and can be varied according to the shape of the pin groove and pin unit.

[0256] Figure 22 This is a top view of the refrigerator according to the second embodiment. Figure 23 This is a perspective view showing the refrigerator of the second embodiment with its first door at its maximum opening angle.

[0257] The other parts of this embodiment are the same as those of the first embodiment, but the guiding unit is different. Therefore, only the characteristic parts of this embodiment will be described below, and the same reference numerals will be used for the same components as those in the first embodiment.

[0258] Reference Figure 22 and Figure 23 In this embodiment, the guiding unit 70 may include a first guide 710 that accommodates the wire 62. The guiding unit 70 may also include a second guide 750 that guides the movement of the first guide 710.

[0259] The first guide 710 may include a curved portion. As an example, at least a portion of the first guide may be formed in an arc shape in the horizontal direction.

[0260] As an example, the curved portion can be configured to protrude in a direction away from the first opening 216 through which the water pipe 61 passes.

[0261] The first guide 710 may also include the first portion and the second portion described in the first embodiment. In this embodiment, the first portion may include a curved portion.

[0262] The first guide 710 may include a first end 710a and a second end 710b. The second end 710b is the end disposed adjacent to the first door 21, and the first end 710a is the end located on the opposite side of the second end 710b.

[0263] With the first door 21 closed, the horizontal distance between one side 10b of the housing 10 and the first end 710a can be less than the horizontal distance between the first side 21c of the first door 21 and the second end 710b.

[0264] The second guide 750 may include a base 751. The second guide 750 may include a shield extending from the base 751.

[0265] The shielding element may include a first shielding element 752 and a second shielding element 753 spaced apart from the first shielding element 752. The first shielding element 752 and the second shielding element 753 may form a space for the first guide element 710 to be disposed.

[0266] The first shielding member 752 may include a first component 752a. The first component 752a may be located on the rear side of the first hinge body 310.

[0267] The first component 752a may be configured to overlap one or more of the first hinge body 310 and hinge cover 350 in the front-rear direction. The first component 752a may be configured to face a portion of the second shield 753.

[0268] The first shield 752 may further include a second component 752c. The second component 752c may be located to the side of the first hinge body 310 or hinge cover 350. The second component 752c may be closer to the first door 21 than the first component 752a. The second component 752c may be configured to face another portion of the second shield 753.

[0269] The horizontal distance (for example, the left-right distance) between the first component 752a and the second shield 753 can be greater than the horizontal distance (for example, the left-right distance) between the second component 752c and the second shield 753.

[0270] The first shielding member 752 may further include a connecting member 752b that connects the first component 752a and the second component 752c.

[0271] The first end 710a of the first guide 710 may be located between the first component 752a and the second shield 753. A portion of the first guide 710 may be located between the second component 752c and the second shield 753.

[0272] A guide hole 755 may be provided on the base 751. The guide hole 755 may extend from the through hole 554 described in the first embodiment. The connection structure between the first guide member and the base 751 is the same as in the first embodiment, therefore detailed description is omitted.

[0273] With the first door 21 closed as a reference, at least a portion of the first guide 710 may be closer to the first shield 752 than the guide hole 755.

[0274] With the first door 21 closed as a reference, the first end 710a of the first guide 710 can overlap with the hinge cover 350 in the front-back direction.

[0275] The guiding unit 70 may further include a third shield 756. The third shield 756 may extend from the base 751. The third shield 756 may be configured to face the first component 752a.

[0276] In this embodiment, the wire 62 may also include a first portion 62a and a second portion 62b located outside the first guide 710 when the first door 21 is closed.

[0277] With the first door 21 closed, the first portion 62a can be disposed adjacent to the first component 752a. The first portion 62a can move towards the second shielding member 753 during the opening of the first door 21. During the opening of the first door 21, the length of the first portion 62a can increase, and the length of the second portion 62b can decrease.

[0278] With the first door 21 open at its maximum opening angle, the first guide 710 can be configured to have a curved portion while the entrance 712a on the first end 710a side faces rearward. In this embodiment, the first portion 62a in the portion adjacent to the first end 710a side of the first guide 710 can be configured as a straight line or a similar shape.

[0279] In this embodiment, when at least a first portion of the first guide 710 is a curved portion, the curvature of the curved portion is reduced, thereby reducing the bending of the wire within the curved portion.

[0280] Figure 24 This is a top view of the first door in the third embodiment.

[0281] The other parts of this embodiment are the same as those of the first or second embodiment; however, the structure in which the second connecting member is integrally formed with the first door differs. Therefore, hereafter, only the characteristic parts of this embodiment will be described, and the same reference numerals will be used for the same components as in the first embodiment.

[0282] Reference Figure 24 In the first door 21, a receiving groove 217 for accommodating the connecting unit may be formed in the hinge receiving portion 211. The receiving groove 217 may be formed by a recess in the bottom surface of the hinge receiving portion 211.

[0283] The second opening 218 may be formed on the bottom surface of the receiving groove 217. An extension 518 of the first guide 510 may be disposed on the bottom surface of the receiving groove 217.

[0284] In this embodiment, the second connecting member of the first embodiment can be omitted, or a portion of the structure of the second connecting member can be integrated with the first door 21.

[0285] A guide wall 219c may be formed in the receiving groove 217. The guide wall 219c can guide the rotation of the first guide member 510. The guide wall 219c can restrict the horizontal movement of the extension 518 relative to the first door 21 during the opening process of the first door 21.

[0286] As an example, the guide wall 219c can protrude upward from the receiving groove 217. The guide wall 219c can protrude from a position spaced apart from the peripheral wall of the receiving groove 217.

[0287] As an example, a plurality of guide walls 219c can be spaced apart. The plurality of guide walls 219c can be configured to face each other or be symmetrical. The plurality of guide walls 219c may include curved portions 219d to allow the extension 518 to rotate. In this case, the second opening 218 can be arranged between the plurality of guide walls 219c.

[0288] Alternatively, the extension 518 can be configured to be surrounded by a single guide wall 219c. In this case, the guide wall 219c may also include a curved portion 219d to allow the extension 518 to rotate.

[0289] A hook hole 219a for fastening the first hook 525 may be provided on the bottom surface of the receiving groove 217.

[0290] The extension wall 522 of the first connecting member 520 can be disposed on the bottom surface of the receiving groove 217. In this case, the extension wall 522 can be located between the guide wall 219c and the peripheral wall of the receiving groove 217.

[0291] According to this embodiment, the movement of the first connecting member 520 relative to the first door 21 during the rotation of the first door 21 can also be restricted.

[0292] Conversely, the first guide 510 can be rotated relative to the first door 21 using the first connecting member 520.

[0293] Figure 25 This is a diagram showing the first gate of the fourth embodiment. Figure 26 This is a top view showing the position of the wire introduced into the first door in the fourth embodiment. Figure 27 This is a diagram showing the state in which the wire of the fourth embodiment is introduced into the first gate.

[0294] Reference Figures 25 to 27In this embodiment, the first door 21 may include a hinge receiving portion 211a that accommodates the first hinge body 310.

[0295] The hinge receiving portion 211a may be formed at a position spaced downward from the top surface 21e of the first door 21. As an example, the hinge receiving portion 211a may be formed by a portion of the back side of the first door 21 being recessed forward.

[0296] The first hinge body 310 may be provided with a first pin unit 320 as described in the first embodiment. A first pin groove 212 for accommodating the first pin unit 320 may be provided on the bottom surface of the hinge receiving portion 211a.

[0297] In this embodiment, the basic structure for rotating the first gate 21 is the same as that described in the first embodiment, so detailed description is omitted.

[0298] The hinge receiving portion 211a can accommodate a hinge cover 650 for covering the first hinge body 310. The hinge receiving portion 211a is located further below than the top surface of the first door 21, thus minimizing the exposure of the hinge cover 650 to the outside.

[0299] In this embodiment, the wire 62 can extend along the inner side of the hinge cover 650 toward the first door 21. The wire 62 can be located within the hinge receiving portion 211a. A through hole 652 for the wire 62 to pass through can be formed in the hinge cover 650. As an example, the through hole 652 can be located on the upper side of the hinge cover 650.

[0300] Therefore, the wire inside the hinge cover 650 can pass through the top surface of the hinge cover 650 and extend upward.

[0301] As an example, at least a portion of the through hole 652 may overlap with the first pin unit 320.

[0302] In this embodiment, during the opening of the first door 21, the rotation center of the first door 21 is arranged adjacent to the first pin unit 320, which has the advantage that if at least a portion of the through hole 652 overlaps with the first pin unit 320, the twisting of the wire 62 during the opening of the first door 21 can be reduced.

[0303] In the first door 21, the upper sidewall 211g of the hinge receiving portion 211a may have a wire opening 211f for the wire 62 to pass through. The upper sidewall 211g of the hinge receiving portion 211a may be separated from the top surface of the hinge cover 350. The wire 62 may be introduced into the first door 21 through the wire opening 211f.

[0304] 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.

[0305] The wire 62 extending upward through the through hole 652 in the hinge cover 650 can be directly introduced into the first door 21 through the wire opening 211f.

[0306] Therefore, it has the advantage of reducing the amount of bending of the wire 62 when it is introduced from the upper side of the hinge cover 650 into the first door 21.

[0307] Figure 28 This is a diagram illustrating the first hinge mechanism and the second hinge mechanism of the fifth embodiment.
