이하, 본 고안의 바람직한 실시예를 첨부도면에 의거 설명한다.Hereinafter, preferred embodiments of the present invention will be described based on the accompanying drawings.

세탁조(1)의 밑면에 구동모터(3)가 고정되며, 구동모터(3)의 구동축(12)에 풀리(5)가 장착되며, 풀리(5)에 장착되는 벨트(7)를 통한 구동모터(3)의 구동력을 선택적으로 단속시켜주는 클러치(8)가 세탁조(1)의 밑면에 장착되며, 코일(10)이 권선되는 스테이터(9)내측으로 구동축(12)이 일체로 고정되는 로우터(11)가 회전가능하게 내설됨은 종래의 구성과 동일하여 이에 대한 설명은 생략하며, 도면부호도 제1도에 표기된 것과 동일하게 표기하였다.The drive motor 3 is fixed to the bottom of the washing tank 1, the pulley 5 is mounted to the drive shaft 12 of the drive motor 3, the drive motor through the belt (7) mounted on the pulley (5) A clutch (8) for selectively controlling the driving force of (3) is mounted on the bottom of the washing tank (1), and a rotor (1) in which the drive shaft (12) is integrally fixed to the inside of the stator (9) where the coil (10) is wound ( 11) is rotatable internally is the same as the conventional configuration and the description thereof will be omitted, and reference numerals are also indicated as shown in FIG.

본 고안의 실시예서는, 제2도에 개략적으로 도시된 바와 같이, 구동축(12)을 지지하는 볼 베어링(13)을 함몰수용하는 수납부(17)를 하우징(15)상부 중앙에 돌출되게 일체형으로 형성하며, 볼 베어링(13)과 수납부(17)의 사이에 구동모터(3)구동시 상,하방향으로 발생되는 로우터(11)의 충격량을 흡수하는 탄성부재(18)가 개재된 것이다.In the embodiment of the present invention, as shown schematically in FIG. 2, an accommodation part 17 for recessing the ball bearing 13 supporting the drive shaft 12 is integrally formed to protrude in the center of the upper part of the housing 15. And an elastic member 18 interposed between the ball bearing 13 and the accommodating portion 17 to absorb the impact amount of the rotor 11 generated in the up and down directions when the driving motor 3 is driven. .

위와 같이 구성된 본 고안의 작동을 설명하면, 구동모터(3)의 스테이터(9)에 권선된 코일(10)에 전류가 인가됨에 따라 형성되는 자력선에 의해 로우터(11)는 정.역방향으로 반복적으로 회전하게 되며, 이와 동시에 볼 베어링(13)(14)에 의해 하우징(15)에 지지된 구동축(12)도 회전하며, 구동모터(3)의 구동력은 구동모터(3)의 풀리(5), 벨트(7), 클러치(8)의 풀리(6)를 차례로 통과해 펄세이터(4)에 전달되며, 클러치(8)에 의해 선택적으로 단속되는 것이다.Referring to the operation of the present invention configured as described above, the rotor 11 is repeatedly in the forward and reverse directions by a magnetic force line formed as a current is applied to the coil 10 wound on the stator 9 of the drive motor (3) At the same time, the drive shaft 12 supported by the housing 15 by the ball bearings 13 and 14 also rotates, and the driving force of the drive motor 3 is the pulley 5 of the drive motor 3, The belt 7 passes through the pulley 6 of the clutch 8 in order to be transmitted to the pulsator 4, and is selectively interrupted by the clutch 8.

이때, 로우터(11)의 정.역방향으로의 방향전환시 발생되는 상.하방향으로의 충격량은, 하우징(15)의 상부 중앙에 돌출되는 수납부(17)에 내설된 충격흡수용 탄성부재(18)에 의해 흡수되므로, 세탁조(1)구동시 구동모터(3)에 의해 진동 및 소음이 세탁조(1)를 통해 세탁조(1)가 매단상태(suspension)를 유지하도록 설치된 외부 하우징(16)에 전달됨이 현저하게 줄어드는 것이다.At this time, the amount of impact in the up-and-down direction generated when the rotor 11 is reversed in the forward / reverse direction is a shock absorbing elastic member built in the housing 17 protruding from the upper center of the housing 15 ( 18), the vibration and noise are driven by the drive motor (3) when driving the washing tank (1) to the outer housing (16) installed so that the washing tank 1 is suspended through the washing tank (1). The delivery is significantly reduced.

또한, 구동모터(3)구동시 발생되는 로우터(11)의 상.하방향으로의 충격량은 구동축(12)을 통해 볼 베어링(13)에 전달되는데, 이는 볼 베어링(13)과 수납부(17)사이에 개재된 탄성부재(18)에 의해 흡수되어 완충되므로 볼 베어링(13)의 파손됨을 방지할 수가 있는 것이다.In addition, the amount of impact in the vertical direction of the rotor 11 generated when driving the drive motor 3 is transmitted to the ball bearing 13 through the drive shaft 12, which is the ball bearing 13 and the receiving portion 17 Since it is absorbed and buffered by the elastic member 18 interposed therebetween, it is possible to prevent the ball bearing 13 from being broken.

이상에서 설명된 바와 같이, 본 고안은 전자동 세탁기를 구동시키는 구동모터의 작동시 발생되는 상.하방향으로의 충격량을 흡수하여 세탁조에 전달됨을 차단하게 되므로, 심야와 같은 늦은 시간에도 세탁조를 사용할 수 있어 값싼 심야전력을 이용함과 동시에 사용자에게 편리성을 제공하며, 구동축을 지지하는 볼 베어링에 전달되는 로우터의 충격량을 흡수하여 볼 베어링의 손상됨을 방지하여 구동모터의 수명을 크게 연장시킬 수 있는 것이다.As described above, the present invention absorbs the amount of impact in the upper and lower directions generated during operation of the drive motor for driving the automatic washing machine to block the transmission to the washing tank, so the washing tank can be used even at a late time such as late at night. In addition to using low-cost late night power, it provides convenience to the user, and absorbs the impact amount of the rotor transmitted to the ball bearing supporting the drive shaft, thereby preventing damage to the ball bearing, thereby greatly extending the life of the driving motor.
