On the other hand, the ball balancer 70 is installed on the inner circumferential surfaces of the front and rear of the rotating drum 40, which rotates by quickly reducing the vibration of the rotating drum 40 which may occur due to an unbalanced mass caused by the weight of the laundry. The rotation of the drum 40 is to be stabilized early.

여기서, 상기 회전드럼(40)의 전면과 후면의 테두리 부분은 상기 볼밸런서(70)가 설치되도록 단차가 형성되어 있으며, 상기 볼밸런서(70)의 테두리부분에는 돌기형태의 결합부재(76)가 마련되고, 상기 회전드럼(40)에는 상기 결합부재(76)가 삽입되어 끼워질수 있는 결합홈(41)이 마련된다.Here, the front and rear edges of the rotary drum 40 is formed with a step so that the ball balancer 70 is installed, and the engaging member 76 of the protrusion shape is formed at the edge of the ball balancer 70. The rotating drum 40 is provided with a coupling groove 41 into which the coupling member 76 may be inserted and fitted.

도2에서 개시된 바와 같이 상기 볼밸런서(70)는 볼(74)이 이동가능하게 수용될 수 있는 레이스(73)가 형성된 제1밸런서하우징(71)과, 상기 제1밸런서하우징(71)을 덮어서 상기 레이스(73)의 개방부가 밀폐되도록 하는 제2밸런서하우징(72)으로 구성된다.As shown in FIG. 2, the ball balancer 70 covers the first balancer housing 71 and the first balancer housing 71 in which a race 73 is formed in which the ball 74 can be movable. The second balancer housing 72 is configured to seal the opening of the race 73.

한편, 상기 제1밸런서하우징(71)의 측면테두리에는 상기 결합부재(75)가 일정간격 이격되어 마련되는데, 상기 결합부재(75)는 상기 결합홈(도1참조,41)에 끼워질 수 있도록 안내하는 경사형태의 안내부(76)와, 상기 결합홈(41)에 걸려서 상기 볼밸런서(70)의 이탈을 방지하는 걸림부(77)로 구성되어져 있다.On the other hand, the side edge of the first balancer housing 71 is provided with the coupling member 75 spaced apart a predetermined interval, the coupling member 75 is to be fitted into the coupling groove (see Fig. 1, 41). It is composed of a guide portion 76 of the inclined shape to guide and a locking portion 77 to prevent the ball balancer 70 from being caught by the engaging groove 41.

도3에서 도시한 바와 같이, 볼밸런서(70)를 상기 회전드럼(40)에 장착을 하는 경우, 볼밸런서(70)를 상기 회전드럼(40)의 전면과 후면에 근접하게 위치시킨 후 각각 그 전면 및 후면과 접촉시키면 그 미는 힘에 의하여 상기 결합부재(75)의 안내부(76)가 상기 결합홈(41) 내부로 삽입되는데, 이때, 상기 볼밸런서(70)는 상하로 약간 수축되나 상기 볼밸런서(70)의 외부재질이 수지로 구성되어 있으므로 약간의 수축이 발생하여도 제품의 품질에는 큰 지장이 없다.As shown in FIG. 3, when the ball balancer 70 is mounted to the rotary drum 40, the ball balancer 70 is positioned close to the front and rear of the rotary drum 40, respectively. The contact portion 76 of the coupling member 75 is inserted into the coupling groove 41 by the pushing force when contacted with the front and rear surfaces, wherein the ball balancer 70 contracts up and down slightly. Since the outer material of the ball balancer 70 is made of resin, there is no significant problem in the quality of the product even if some shrinkage occurs.

이후 상기 안내부(76)가 완전히 삽입되면 상기 걸림부(77)가 상기 결합홈(41)의 일측면이 위치하게 되는데, 이와 같이 상기 걸림부(77)가 상기 결합 홈(41)에 완전하게 삽입이 된 상태에서는 상기 걸림부(77)에 의하여 상기 볼밸런서(70)가 상기 결합홈(41)에 단단하게 결착된 상태를 취하므로 상기 볼밸런서(70)가 이탈방향으로 결합해제되는 것이 대단히 어렵게 된다.After the guide portion 76 is completely inserted, the engaging portion 77 is located on one side of the coupling groove 41, in this way the locking portion 77 is completely in the coupling groove 41 In the inserted state, since the ball balancer 70 is firmly fixed to the coupling groove 41 by the catching part 77, the ball balancer 70 is disengaged in the detaching direction. Becomes difficult.

한편, 이와 같은 결착방식과 다른 방식을 보면, 도4에서 도시한 바와 같다.On the other hand, look at the different from the binding method, as shown in FIG.

즉, 제1실시예에서는 상기 회전드럼(40)의 내주면에 결합홈(41)이 형성되고, 상기 결합부재(76) 또한 상기 결합홈(41)의 위치에 대응되도록 상기 볼밸런서(70)의 외측테두리면에 형성되나, 도4에서 나타난 제2실시예에서는 상기 회전드럼(40)의 전면부와 후면부에 결합홈(41)이 형성되고, 이에 대응되도록 상기 볼밸런서(70)의 전면 또는 후면에 결합부재(75)가 형성된다.That is, in the first embodiment, the coupling groove 41 is formed on the inner circumferential surface of the rotary drum 40, and the coupling member 76 also corresponds to the position of the coupling groove 41 of the ball balancer 70. Although formed on the outer edge surface, in the second embodiment shown in Figure 4, the coupling groove 41 is formed in the front and rear of the rotary drum 40, so that the front or rear of the ball balancer 70 The coupling member 75 is formed.

그리고, 여기서의 상기 결합부재(75)는 제1실시예에서의 돌기형태가 아닌 후크형태로 마련된다. In this case, the coupling member 75 is provided in a hook shape instead of a protrusion shape in the first embodiment.

도5에서 도시한 바와 같이, 상기 결합부재(75)는 제1실시예에서의 구성과 달리 상기 제2밸런서하우징(72)의 상면에 상호 일정간격 이격되어 복수개가 형성되어 있으며, 그 구체적인 구성은 상기 제2밸런서하우징(72)의 상면에서 일정길이만큼 연장되어 있는 연장부(78)와, 상기 연장부(78)의 단부에서 상기 제2밸런서하우징(72)의 외주방향으로 연장되어 있는 걸림턱(79)으로 구성되어 있다.As shown in FIG. 5, unlike the configuration in the first embodiment, a plurality of coupling members 75 are formed on the upper surface of the second balancer housing 72 with a predetermined interval spaced apart from each other. An extension 78 extending from the upper surface of the second balancer housing 72 by a predetermined length, and a locking jaw extending in the circumferential direction of the second balancer housing 72 from an end of the extension 78. It consists of (79).

본 실시예에서는 상기 결합부재(75)가 상기 제2밸런서하우징(72)에 설치된 것으로 예를 들었으나, 제1밸런서하우징(71)에 형성되어도 무방하다.In the present embodiment, the coupling member 75 is exemplified as being installed in the second balancer housing 72, but may be formed in the first balancer housing 71.

도6에서 도시한 바와 같이, 상기 볼밸런서(70)를 상기 회전드럼(40) 결착하는 상태를 보면 상기 볼밸런서(70)를 상기 회전드럼(40)의 전면과 후면에 위치시킨 후 상기 결합부재(75)를 상기 결합홈(41)에 삽입시킨다.As shown in FIG. 6, when the ball balancer 70 is attached to the rotary drum 40, the coupling member is located on the front and rear surfaces of the rotary drum 40. Insert 75 into the coupling groove 41.

그런데, 상기 결합홈(41)은 일측이 단차지게 형성되는데, 여기서, 상기 결합홈(41)의 구성을 보면 상기 결합부재(75)의 연장부(78)와 걸림턱(79)이 전후방향으로 자유롭이 삽입 및 이탈될 수 있는 제1결합홈(42)과, 상기 제1결합홈(42)의 일측방향으로 연장되며 상기 연장부(78)만 좌우이동가능하도록 상기 연장부(78) 두께 정도의 슬릿형태로 구성되는 제2결합홈(43)을 포함한다.By the way, one side of the coupling groove 41 is formed to be stepped, where the configuration of the coupling groove 41, the extension portion 78 and the locking step 79 of the coupling member 75 in the front and rear direction The first coupling groove 42 which can be freely inserted and detached, and extends in one direction of the first coupling groove 42, the thickness of the extension portion 78 so that only the extension portion 78 can move left and right The second engaging groove 43 is configured in the form of a slit.

상기 제2결합홈(43)의 높이를 상기 제1결합홈(42)의 높이보다 낮게한 이유는 상기 결합부재(75)의 연장부(78)가 상기 제2결합홈(43)에 위치한 상태에서 상기 걸림턱(79)이 상기 제2결합홈(43)의 상부에 걸려서 전체적으로 상기 볼밸런서(70)가 전방 또는 후방으로 이탈되지 않도록 하기 위함이다. The reason why the height of the second coupling groove 43 is lower than the height of the first coupling groove 42 is that the extension portion 78 of the coupling member 75 is located in the second coupling groove 43. In order to prevent the locking jaw 79 is caught in the upper portion of the second coupling groove 43 so that the ball balancer 70 is not separated from the front or rear as a whole.

따라서, 상기 결합부재(75)를 상기 제1결합홈(42)에 삽입시킨 후, 상기 볼밸런서(70)를 상기 제2결합홈(43) 방향으로 살짝 회전시키면, 상기 결합부재(75)의 연장부(78)가 상기 제2결합홈(43)의 안내를 받아 이동하며, 이에 따라서 상기 걸림턱(79)이 상기 제2결합홈(43)의 상부에 위치하게 됨으로써 상기 볼밸런서(70)의 결착이 완료되는 것이다. Therefore, after the coupling member 75 is inserted into the first coupling groove 42, when the ball balancer 70 is slightly rotated in the direction of the second coupling groove 43, the coupling member 75 may be rotated. The extension portion 78 is moved under the guidance of the second coupling groove 43, and accordingly the locking jaw 79 is located above the second coupling groove 43, thereby the ball balancer 70 Will be completed.

이와 같은 본 발명에 의하여 스크류 결합과정이나 용접공정과 같은 접합공정이 없이도 볼밸런서와 회전드럼을 결합시킬 수 있으므로 조립공정이 간소화되며 그 구성요소의 수량과 공정소요시간 등이 감소하여 조립생산성을 증대시킬 수 있다는 장점이 있다. According to the present invention, it is possible to combine the ball balancer and the rotating drum without a screw joining process or a joining process such as a welding process, which simplifies the assembly process and reduces the quantity and process time of the components, thereby increasing assembly productivity. The advantage is that you can.
