Abstract

본 발명은 세탁시 물샅 및 세탁물의 회전력에 의해 발생되는 세탁조의 역회전을 방지하기 위하여 설치한 토션 스프링과 원웨이 베어링의 복합설치구조에 관한 것이다.The present invention relates to a complex installation structure of a torsion spring and a one-way bearing installed to prevent the reverse rotation of the washing tank generated by the washing force and the rotational force of the laundry during washing.

본 발명은 원웨이 베어링(1)의 외경보다 적은 내경으로 토션 스프링(2)을 감아 올리고 상기 토션 스프링(2) 말단부 내경은 아래쪽 내경(4)보다 작게 하여 토션 스프링(2)의 내주에 원웨이 베어링 (1)을 삽입하여 세탁조와 기계결합에 의해 일체로 된 드럼 어셈블리(5)의 상부축(6)에 끼워 안착시키고 토션 스프링(2)의 하부 끝단에 연장된 아암(arm;7)에 고리(8)을 설치하여 이 고리(8)를 기어 메카니즘 어셈블리의 브레이크 기능에 사용되는 로드(rod;9)의 두부(10)에 삽입하며 여기에서 고리(8)의 내경은 로드(9)의 두부(10)외경보다 크게 설치된 구조를 특징으로 한다.The present invention winds the torsion spring (2) to an inner diameter less than the outer diameter of the one-way bearing (1) and the inner diameter of the distal end portion of the torsion spring (2) is smaller than the lower inner diameter (4) one-way around the inner circumference of the torsion spring (2) Insert the bearing (1) into the upper shaft (6) of the drum assembly (5), which is integrated by a washing tank and mechanical coupling, and hooked into an arm (7) extending at the lower end of the torsion spring (2). (8) is installed to insert this ring (8) into the head (10) of the rod (9) used for the brake function of the gear mechanism assembly, where the inner diameter of the ring (8) is the head of the rod (9). (10) It is characterized by the structure installed larger than the outer diameter.
