Specifically, the hinge link 200 of the hinge assembly 100 may be directly connected to the inner surface 22 of the door 20 but rotatably provided to the door 20 . Alternatively, the door coupling bracket 120 may fix the hinge assembly 100 to the inner surface 22 of the door 20 by a coupling method other than screw coupling.

The hinge assembly 100 may include a body-side opening 110a communicating with the inside of the body 10 and a door-side opening 120a communicating with the inside of the door 20 .

Specifically, a body-side opening 110a is formed at one end coupled to the body 10 of the hinge assembly 100, and a communication hole (not shown) through which the outside and the inside of the body 10 communicate can be formed. The body-side opening 110a and the communication hole of the body 10 are formed at positions corresponding to each other, so that the hinge assembly 100 communicates with the inside of the body 10 .

Similarly, a door-side opening 120a is formed at the other end coupled to the door 20 of the hinge assembly 100, and a communication hole (not shown) through which the outside and the inside of the door 20 communicate with each other is formed in the door 20. can be formed The opening 120a on the door side and the communication hole of the door 20 may be formed at positions corresponding to each other so that the hinge assembly 100 communicates with the inside of the door 20 .

Accordingly, the supply member 30 may pass through the inside of the hinge assembly 100 and connect between the main body 10 and the door 20 . In other words, the supply member 30 is provided to pass through the body-side opening 110a, the inside of the hinge assembly 100 and the door-side opening 120a, so that the body 10 and the door 20 can be connected. .

The body-side opening 110a may be formed on the body coupling bracket 110 . Similarly, the door-side opening 110b may be formed on the door coupling bracket 120 . However, it is not limited thereto, and the body-side opening 110a and the door-side opening 120a may be variously formed on the hinge assembly 100 .

As in the case described above, when the hinge assembly 100 does not include the body coupling bracket 110 and the door coupling bracket 120, the body-side opening 110a and the door-side opening 120a of the hinge assembly 100 It may be formed in a different location. For example, a plurality of through-holes 242 (refer to FIG. 9 ) through which the supply member 30 passes may be formed on the fourth link member 240 of the configuration of the hinge link 200 to be described later. At this time, among the plurality of through-holes 242, the through-hole 242a adjacent to one end to which the fourth link member 240 is coupled to the main body 10 may function as the main body-side opening 110a. For reference, when the hinge assembly 100 includes the body coupling bracket 110, the fourth link member 240 above is coupled to the main body 10. The fourth link would have been coupled to the body coupling bracket 110 It means one end of the member 240.

Similarly, a plurality of through-holes 222 (see FIG. 11 ) through which the supply member 30 passes may be formed on the second link member 220 of the configuration of the hinge link 200 to be described later. At this time, among the plurality of through-holes 222 , the through-hole 222b adjacent to one end where the door link 220 is coupled to the door 20 may function as the door-side opening 120a. For reference, one end of the above door link 220 coupled to the door 20 is the door link 220 that would have been coupled to the door coupling bracket 120 when the hinge assembly 100 includes the door coupling bracket 120 means one end of

The hinge assembly 100 may include a cover housing 130 covering one surface of the hinge assembly 100 . Specifically, the cover housing 130 covers a side surface bent in a lateral direction of the body 10 from one surface where the body coupling bracket 110 is coupled to the body 10, so that the hinge assembly 100 is removed from the outside. It prevents the inside from being seen and can improve the quality of the exterior.

The hinge assembly 100 may include a hinge link 200 . The hinge link 200 is coupled to the body 10 and the door 20 and may be formed such that the door 20 is rotatably connected to the body 10 . When the hinge assembly 100 includes the body coupling bracket 110 and the door coupling bracket 120, the hinge link 200 is connected to the body coupling bracket 110 and the door coupling bracket 120 so that the body 10 And coupled to the door 20, the hinge link 200 may be rotatably coupled to the body coupling bracket 110 and the door coupling bracket 120.

The hinge link 200 may be formed so that the supply member 30 passes through and is disposed. Specifically, supply guides 221 and 241 may be formed in at least a portion of the hinge link 200 so that the supply member 30 may be disposed therein. Accordingly, even if the hinge link 200 moves inside the hinge assembly 100 according to the opening and closing of the door 20, the supply member 30 does not interfere with the movement of the hinge link 200 and the hinge assembly 100 It can be placed inside.

When the hinge assembly 100 includes only a single axis of rotation so that the door 20 is rotatable, when the door 20 is opened at an angle greater than or equal to a certain angle, interference with adjacent objects may occur. For example, when the refrigerator 1 is installed in a built-in manner in a cabinet (not shown) or disposed adjacent to other home appliances in a left-right direction (see FIG. 13), the door 20 ) may not be able to sufficiently open the door 20 due to interference with adjacent objects. In this case, as described above, inconvenience may be caused when the user performs a use action such as taking out food or the like from the storage compartment 13 of the refrigerator 1.

However, when the refrigerator 1 is arranged to have a sufficient separation distance from adjacent objects to the extent that interference between the door 20 and adjacent objects does not occur even when the door 20 is sufficiently opened, the overall aesthetics may be damaged.

To solve this problem, the hinge assembly 100 may include a plurality of link members 210, 220, 230, and 240. As the plurality of link members 210, 220, 230, and 240 are rotatably connected to each other around the plurality of rotation axes X1, X2, X3, X4, X5, X6, and X7, the door 20 opens. When it is opened, it moves forward toward the front of the refrigerator 1 and rotates to open. In other words, when the door 20 is opened, the door 20 may rotate and open as if drawn toward the front of the refrigerator 1 .

At this time, one end of the first link member 210 rotatably coupled to the body 10 or the body coupling bracket 110 may be disposed adjacent to the body-side opening 110a. Accordingly, the length penetrating the inside of the hinge assembly 100 may be reduced so that the supply member 30 penetrates the body-side opening 110a and extends toward the door-side opening 120a.

The first link member 210 may form a first accommodating space S1 therein to accommodate at least a portion of the door links 220 and 230 and the fourth link member 240 .

In addition, the door 20 may more stably rotate with respect to the main body 10 by the plurality of door links 220 and 230 . However, it is not limited thereto, and the door links 220 and 230 may be configured differently. For example, even if the door 20 is connected to the first link member 210 by a single second link member 220, the door 20 rotates with respect to the main body 10 to open and close the storage compartment 13. can do.
