The fastening hole 312 is formed on the left side of the first plate 311 And the second plate 315 are disposed on the right side of the first plate 311. A hinge plate (not shown) disposed on the left side of the horizontal frame 150 includes a fastening hole 312 and a second plate 315) is the reverse.

4, the hinge shaft guide 340 is inserted into the guide insertion hole 318 in a directional manner and a hinge shaft insertion hole 341 is formed in the hinge shaft guide 340. [

6, the hinge shaft guide 340 includes a hinge shaft insertion hole 341 disposed at the center of the hinge shaft guide 340 and a hinge shaft insertion hole 341 May be disposed eccentrically to one side of the center of the hinge shaft guide 340 and may be selected according to the distance between the two side doors.

7, the hinge shaft guide 340, which is arranged so that the hinge shaft insertion hole 341 is eccentrically eccentrically disposed at one side of the center of the hinge shaft guide 340, is located on the left or right side of the center of the hinge shaft guide 340 The difference between A and B is 1.0 mm to 2.0 mm, and the distance between doors arranged on both sides is 1.0 mm to 2.0 mm. This will be described below again.

On the other hand, the hinge shaft insertion hole 341 is formed with a protrusion receiving groove 345 extending outwardly from the periphery and on which the protrusion 331 is seated.

In the present embodiment, the protrusion seating grooves 345 are formed on both sides of the hinge shaft insertion holes 341, but the number of the protrusion seating grooves 345 may vary according to the embodiment. In addition, the projection seating grooves 345 may be formed continuously along the circumference of the hinge shaft insertion hole 341 according to the embodiment.

The hinge shaft 330 inserted into the hinge shaft insertion hole 341 and to which the door is rotatably mounted is constituted by a shaft portion 331 and a projection portion 333 as shown in Fig.

The shaft portion 331 is a portion where the door is rotatably mounted. The lower end of the first door 210 and the upper end of the third door 230 are rotatably mounted on the shaft portion 331 disposed on the left side and the shaft portion 331 disposed on the right side is rotatably mounted on the second door 220 And the upper end of the fourth door 240 are rotatably mounted.

The protruding portion 331 is a portion that is seated in the protruding portion receiving groove 345 and protrudes from the outer surface of the shaft portion 331. In this embodiment, a strip-shaped protruding surface 332 is formed along the circumference at the center of the protruding portion 331, and protruding portions 331 are formed on both sides of the protruding surface 332 respectively. This is because protruding portions 331 are formed on both sides of the shaft portions 331 at positions corresponding to the protruding portion mounting grooves 345 as the protruding portion mounting grooves 345 are formed on both sides of the hinge shaft insertion holes 341 It is. The protrusion seating grooves 345 may be formed continuously along the periphery of the hinge shaft insertion hole 341 so that the protrusions 331 also extend continuously along the circumference of the shaft portion 331 at the corresponding position Can be formed. As such, the number and arrangement of the projections 331 vary depending on the number and arrangement of the projection receiving grooves 345.

Hereinafter, the operation of the refrigerator having the hinge structure capable of adjusting the interval between the doors according to the present invention will be described.

6, a hinge shaft guide 340 having a hinge shaft insertion hole 341 disposed at the center of the hinge shaft guide 340 is inserted into a guide insertion hole (not shown) of the hinge plate 310 318).

The hinge shaft insertion hole 341 as shown in FIG. 7 may be eccentrically disposed at a center of the hinge shaft guide 340 in any one side of the hinge shaft guide 340 when the distance between doors disposed on both sides of the refrigerator is reduced or widened The hinge shaft guide 340 is assembled to the guide insertion hole 318 of the hinge plate 310. [

At this time, the hinge shaft insertion hole 341 is eccentric from the center of the hinge shaft guide 340 to the left or right by 0.5 mm to 1.0 mm, so that only one of the hinge shaft insertion holes 341 is eccentrically formed in the hinge shaft guide 340 340 is used, the interval correction amount of the door is 0.5 mm to 1.0 mm. In the case where the hinge shaft guide 340 having the eccentric hinge shaft insertion hole 341 is used in both doors, the interval correction amount of the door is 1.0 mm To 2.0 mm.

Since the difference in the distance between the two side doors is usually within 3 mm, it is sufficient that the distance between the door and the door is 1.0 mm to 2.0 mm. If more precise door spacing is desired, A and A of the hinge shaft guide 340 B can be adjusted according to the interval of the doors by preparing the plurality of hinge shaft guides 340 at equal intervals and adjusting the interval of the door more finely.

As described above, according to the refrigerator having the hinge structure capable of adjusting the distance between the doors according to the present invention, the hinge plate 310 and the hinge shaft 330 can be assembled to reduce the assembling error when the hinge plate 310 and the hinge shaft 330 are assembled, The hinge shaft guide 340, which is a separate component, is assembled to the hinge shaft 330, thereby improving assembling performance.

The hinge shaft insertion hole 341 is disposed at the center of the hinge shaft guide 340 and the hinge shaft insertion hole 341 is disposed eccentrically to one side of the center of the hinge shaft guide 340 The hinge shaft insertion hole 341 can be assembled by replacing only the eccentric hinge shaft guide 340 with any one side of the hinge shaft insertion hole 341. Therefore, Can be adjusted.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. It is to be understood that various changes and modifications may be made without departing from the scope of the appended claims.
