The baths 5 are rotated in one direction at a high speed to allow dehydration.

전동기 회전 구동력을 탈수조(5)와 교반익(6)에 선택적으로 전달하기 위한 동력구분전달장치(10) 구성은 제2도와 같이 전동기(8)의 회전구동력을 벨트로 전달받는 풀리(9)와, 풀리(9)와 결합되고 기어군(16)이 매게되어 풀리의 회전구동력을 교반익축(12)에 전달하는 구동축(17)과, 상기 탈수조축(11)과 결합되며 기어(16a, 16b)등으로 되는 기어군(16)을 감싸는 기어하우징(15)과, 상기 기어하우징(15)과 구동축(17)이 결합되거나 또는 각각 분리되게 하는 클러치스프링(14), 스프링블록(23), 클러치보스(24), 동작캠, 브레이크레버등이 설치되며, 탈수조축(11) 또는 기어하우징(15)에는 볼베어링(19)이 결합되는 구성으로 되어 있다.The power distribution unit 10 for selectively transmitting the motor rotational driving force to the dehydration tank 5 and the stirring blade 6 has a pulley 9 which receives the rotational driving force of the electric motor 8 as a belt as shown in FIG. And, coupled to the pulley (9) and the gear group 16 is tied to the drive shaft (17) for transmitting the rotational driving force of the pulley to the stirring blade (12), coupled with the dehydration tank shaft 11 and gears (16a, 16b) Gear housing 15 enclosing the gear group 16, and the clutch spring 14, the spring block 23, the clutch to couple or separate the gear housing 15 and the drive shaft 17, respectively. A boss 24, an operation cam, a brake lever, and the like are installed, and the ball bearing 19 is coupled to the dehydration shaft 11 or the gear housing 15.

이와 같은 구성에서 선택스위치 조작과 자동프로그램의 명령에 따라 세탁시에는 전동기 회전구동력이 구동축(17)에만 전달되어 구동축(17)과 연결되는 교반익축(12)이 회전되고 따라서 교반익(6)이 좌, 우 회전하면서 세탁 및 헹굼공정이 진행되고 탈수시에는 전동기 회전구동력이 기어하우징(15)과 구동축(17)에 각각 전달되고 따라서 탈수조(5) 및 교반익(6)이 일방향으로 함께 회전됨에 따라 원심분리 작용에 의해 탈수공정이 진행된다.In this configuration, upon washing according to the selection switch operation and the command of the automatic program, the motor rotary driving force is transmitted only to the drive shaft 17 so that the stirring blade 12 connected to the drive shaft 17 is rotated, so that the stirring blade 6 is rotated. The washing and rinsing process proceeds while rotating left and right, and during dehydration, the motor driving force is transmitted to the gear housing 15 and the drive shaft 17, respectively, so that the dehydration tank 5 and the stirring blade 6 rotate together in one direction. As a result, the dehydration process proceeds by centrifugation.

한편 세탁시 교반익(6)이 좌, 우 회전함에 따른 세탁물의 부하와 회전수류에 의해 발생하는 탈수조의 역회전을 방지하기 위해 하나의 원통체내에 라쳇트홈을 형성하고 상기 라쳇트홈내에 원형의 로울러가 삽입된 로울러클러치(18)를 구비하여 상기 로울러클러치의 로울러가 탈수축 또는 탈수축과 결합되는 기어하우징(15)의 원통부(15a)에 접하게 하고 로울러클러치를 하우징에 의해 동력구분 전달장치(10)의 몸체에 고정하는 로울러클러치를 이용한 탈수조 역회전 방지장치가 본 출원인에 의해 선출원되어 실용신안공보 제746호 공고번호 제85-2876호(명칭 : 전자동 전기 세탁기의 탈수조역회전 방지장치)에 알려져 있다.On the other hand, in order to prevent the reverse rotation of the dehydration tank caused by the load of the laundry and the rotational water flow as the stirring blade 6 rotates left and right during washing, a ratchet groove is formed in one cylindrical body and a circular roller is formed in the ratchet groove. Is provided with a roller clutch 18 inserted therein so that the roller of the roller clutch comes into contact with the cylindrical portion 15a of the gear housing 15 coupled with the deshrinkment or deshrinkage, and the roller clutch is driven by the housing. The dehydration tank reverse rotation prevention device using the roller clutch fixed to the body of 10) was first filed by the present applicant, Utility Model Publication No. 746 Publication No. 85-2876 (name: dehydration tank reverse rotation prevention device of the automatic washing machine) Known for.

그런데 종래의 이와 같은 장치에 있어서는 회전축을 지지하기 위해 탈수조축 또는 기어하우징(15) 외주에 볼베어링(19)을 설치하게 되는데 볼베어링(19)의 지지점으로부터 멀어질수록 먼 위치의 탈수조축 또는 기어하우징(15)의 진동, 기울어짐이 크게 되어 볼베어링(19)과 로울러클러치(18)를 분리하여 설치하였을때는 탈수조축 및 기어하우징(15)의 진동으로 로울러클러치(18)의 로울러와 탈수조축 또는 기어하우징(15) 사이의 적절한 틈새가 유지되지 않게 되어 소음이 발생하고 탈수조축 기동불량이 발생하고 또한 진동, 기울어짐으로 인해 탈수조축 또는 기어하우징(15)의 원통부 외주면과 로울러클러치의 접촉거리가 짧아지므로 로울러클러치의 제동력이 제대로 발휘되지 않고 아울러 로울러클러치의 수명이 단축되는 등의 문제점이 있었다.By the way, in the conventional device such as this, the ball bearing 19 is installed on the outer circumference of the dewatering shaft or the gear housing 15 to support the rotating shaft. The further away from the supporting point of the ball bearing 19, the farther the dewatering shaft or the gear housing ( 15) When the ball bearing 19 and the roller clutch 18 are separated and installed due to the large vibration and inclination, the roller and the dewatering shaft or the gear housing of the roller clutch 18 may be damaged by the vibration of the dehydration shaft and the gear housing 15. (15) Since the proper clearance between them is not maintained, noise is generated, dehydration shaft maneuvering fault occurs, and the contact distance between the outer peripheral surface of the cylindrical part of the dehydration shaft or the gear housing and the roller clutch is short due to vibration and tilting. Since the braking force of the roller clutch is not properly exhibited, the life of the roller clutch is shortened.

또한 로울러클러치(18)를 탈수조축이 역방향(탈수시 탈수조축 회전방향을 정방향, 그 반대방향을 역방향이라 함)으로 회전시 탈수조축과 함께 회전되지 않도록 동력구분 전달장치의 비회전부분 일측에 고정시켜야 하기 때문에 별도의 고정수단이 필요하게 되어 부품수가 증가하게 되고 설치시 작업공정이 까다롭게 되는 문제점이 있었다.In addition, the roller clutch 18 is fixed to one side of the non-rotating part of the power division transmission device so that the dehydration shaft is not rotated together with the dehydration shaft when the dehydration shaft rotates in the reverse direction (when dewatering, the rotation direction of the dehydration shaft is called a forward direction and the opposite direction is the reverse direction). Because of the need for a separate fixing means to increase the number of parts, there was a problem that the work process is difficult to install.

본 고안은 이와 같은 종래의 제반 문제점을 해결하기 위해 고안된 것으로써 볼베어링과 로울러클러치를 일체로 하여 보다 간단히 볼베어링과 로울러클러치를 설치함으로써 효과적인 역회전을 차단시킬 수 있게 함과 아울러 소음을 저감시키고 탈수시 탈수조축의 회전을 원활히 하고 부품수를 줄일 수 있게 있도록 하려는 것이다.The present invention has been devised to solve such problems in the related art, and the ball bearing and the roller clutch are integrated into the ball bearing and the roller clutch so that the effective reverse rotation can be blocked, and the noise can be reduced and dewatered. The aim is to make the spinneret rotate smoothly and reduce the number of parts.
