도시한 바에 의하면, 제 2베어링 회전판(410)의 볼구름부(411)의 접촉궤적(A)에는 중심부를 기준으로 일정각도 이격되어 수개의 구름홈(412)이 형성된다.As shown in the drawing, the contact traces A of the ball cloud portion 411 of the second bearing rotating plate 410 are spaced at a predetermined angle with respect to the center to form several cloud grooves 412.

상기 구름홈(412)이 형성됨으로 인해서, 김치저장고 도어(20,도1참조)의 개폐작동에 따라 탄성부재(330)끝단의 움직임은 볼베어링의 제 2베어링 회전판(410)에 전달되고, 상기 제 2베어링 회전판(410)이 회전함에 따라서 상기 볼(440)이 볼구름부(411)의 접촉궤적(A)위를 움직이게 된다.Since the rolling groove 412 is formed, the movement of the end of the elastic member 330 according to the opening and closing operation of the kimchi storage door 20 (see Fig. 1) is transmitted to the second bearing rotary plate 410 of the ball bearing, As the two bearing rotating plate 410 rotates, the ball 440 moves on the contact trace A of the ball cloud 411.

따라서, 도어가 열림에 따라 상기 구름홈(412)이 형성된 제 2베어링 회전판(410)이 회전을 하면 상기 구름홈(412)부분에서는 상기 제 2베어링 회전판(410)의 움직임이 일시정지되어 도어가 멈추게 되고, 상기 구름홈(412)이 형성되지 않은 볼구름부(411)에서는 제 2베어링 회전판(410)이 회전을 하게 되어 도어가 열리게 되고, 결국 도어의 다단개폐가 이루어진다.Therefore, when the second bearing rotary plate 410 having the rolling groove 412 is rotated as the door is opened, the movement of the second bearing rotary plate 410 is temporarily stopped at the rolling groove 412. In the ball cloud 411 in which the rolling groove 412 is not formed, the second bearing rotary plate 410 rotates to open the door, and thus the door is opened and closed in multiple stages.

상술한 바와 같이 본 발명에 의하면, 사용자의 개폐목적에 따라서 도어의 개폐시 도어의 다단개폐가 이루질 수 있어 사용자의 편의성과 제품선택의 다양성을 가져올 수 있다. As described above, according to the present invention, the multi-stage opening and closing of the door can be made when the door is opened and closed according to the purpose of opening and closing the user, which can bring user convenience and variety of product selection.
