The rotating member 50 is screw-mounted and fixedly mounted to the rear region of the door 5 through the door support flange 52, and covers the open surface of the hinge housing 70 and is fastened to the cover plate 100. Screw assembly is fixed to the top of the rear surface of the main body 6 through the main body support flange (102).

As such, in the state in which the rotating member 50 and the hinge housing 70 of the hinge assembly are assembled, when the door 5 is opened, the rotating member 50 fixed to the door 5 side is flipped back to move. When the door 5 is fully opened, the door 5 is flipped to about 90 degrees with respect to the upper end of the main body 6, and no further rotation is caused by contact between the outer surface of the rotating member body 51 and the outer surface of the hinge housing 70. Will not.

In addition, as shown in FIG. 7, when the door 5 is closed, the rotating member 50 is bent forward again to move, and the semicircular cam portion of the pressing piece 65 in the hinge housing 70 compartment is supported by the support piece ( The cam surface of 90) slides while making a rolling contact.

At this time, as a result of the cam motion of the pressing piece 65 and the support piece 90, the support piece 90 is pushed downward, and the spring member 80 connected to the support piece 90 receives a compressive force.

As the door 5 is closed, the support piece 90 further exerts a force on the pressing piece 65, thereby increasing the resistance by the elastic restoring force of the spring member 80. Since the closing speed of the door 5 is in contact with the main body 6, the closing speed of the door 5 is remarkably reduced, and the impact is alleviated.

If the elastic restoring force of the spring member 80 is weak and the force supporting the door 5 is weak, tighten the adjusting screw 120 to adjust the elastic restoring force of the spring member 80.

As described above, according to the hinge assembly which hinges the door that opens and closes the storage compartment by pivoting in one direction to the upper surface of the kimchi storage body according to the present invention, it is necessary to separately provide a hinge coupling part when forming the body or the door. The hinge assembly can be hinged to the main body by simply assembling and mounting the hinge assembly to the Kimchi storage body without the addition of a separate outer case and parts, thereby increasing the production efficiency due to a much simpler process than the conventional production process. It prevents the flow of the left and right and relieves the opening and closing speed of the door by the elastic restoring force of the spring member has the effect of preventing the opening and closing shock of the door and to enable stable opening and closing.
