본 고안은 세탁조와 탈수조가 분리된 2조식 세탁기에 있어서, 탈수조의 정지시에 소요되는 모터장지시간을 최소화하고, 제동시에 발생되는 마찰소음을 저감시킬 수 있는 탈수모터브레이크장치에 관한 것이다.The present invention relates to a dewatering motor brake device in a two-chamber washing machine in which a washing tank and a dewatering tank are separated, which minimizes the motor holding time required when the dehydration tank is stopped and reduces the friction noise generated during braking.
종래으 탈수모터 브레이크장치는 통상 제1도에서와 같이 모터축(1)에 고정괸 브레이크 드럼(2)의 근접위치에, 힌지(3)로 고정되고 와이어(4)로 작동되며 일측에 브레이크 드럼(2)과 마찰하는 브레이크 블럭(5)을 구비한 작동간(6)을 설치하여, 모터의 회전시(탈수작동)에는 와이어(4)를 당겨 브레이크 드럼(2)과 블럭(5)을 분리시키고, 정지시(탈수완료)에는 와이어(4)를 이완시 브레이크 블럭(5)이 브레이크 드럼(2)에 마찰되도록 구성되어 있었다. 도시하지는 않았으나, 작동간(6)은 힌지(3)를 브레이크 드럼(2) 방향의 탄성을 갖도록 설치되었음은 물론이다.Conventionally, the dewatering motor brake device is fixed to the hinge shaft 3 and operated by a wire 4 at a position adjacent to the brake drum 2 fixed to the motor shaft 1, as shown in FIG. An operation section 6 having a brake block 5 in friction with (2) is provided, and the brake drum 2 and the block 5 are separated by pulling the wire 4 when the motor rotates (dehydration operation). The brake block 5 was configured to rub against the brake drum 2 when the wire 4 was loosened at the time of stopping (dehydration completion). Although not shown, the operating section 6 is installed so that the hinge 3 has elasticity in the direction of the brake drum 2.
마찰력(제동력)은 마찰면적의 크기와 비례함은 주지와 같으며 이에 따라 근래에는 브레이크 드럼(2)과 블럭(5)에 서로 대응하는 쐐기형의 홈과 돌기를 구비하여 마찰면을 확대시키므로써 제동력을 제고시킨 구성도 제안된 바 있다.It is well known that the frictional force (braking force) is proportional to the size of the frictional area. Accordingly, in recent years, the friction surface is enlarged by having wedge-shaped grooves and protrusions corresponding to each other in the brake drum 2 and the block 5. A configuration that improves braking power has also been proposed.
이는 즉, 제2도에서와 같이 브레이크 드럼(2)과 블럭(5)을 구성한 경우 마찰면적이 적어 제동력이 떨어지므로 탈수조의 정지시간이 길어지고 마찰소음은 커지게 되는 문제점을 해소하기 위함이 었다.In other words, when the brake drum 2 and the block 5 are configured as shown in FIG. 2, the braking force is reduced because the friction area is small, so that the stopping time of the dehydration tank becomes long and the friction noise increases. .
그러나, 마찰면을 확대하기 위해 쐐기형홈과 돌기를 설치한 경우에도 제동력을 향상되어 마찰면적의 확대에 따라 소음 및 마찰열은 상대적으로 증가하여 소음발생 및 브레이크 블럭(5)의 극심한 마모를 초래하는 문제점을 유발하였다.However, even when the wedge-shaped groove and the protrusion are installed to enlarge the friction surface, the braking force is improved, and the noise and frictional heat increase relatively as the friction area is enlarged, resulting in noise generation and extreme wear of the brake block 5. Induced.
이에따라 본 고안은 마찰면적의 확대로 제동소요 시간을 최소화하고 이에 수반되는 소음 및 부품마모를 최대한 억제시킬 수 있게 된 탈수모터 브레이크 장치를 제공함에 그 목적이 있는 바, 이하에서 첨부도면에 의해 본 고안을 상세히 설명한다.Accordingly, the present invention has a purpose to provide a dehydration motor brake device that can minimize the braking time due to the expansion of the friction area and to minimize the noise and parts wear associated with it, the present invention by the accompanying drawings below It will be described in detail.
본 고안은 제3도 및 제4도에서와 같이 브레이크 블럭(5A)의 쐐기형 마찰돌기(5A-1)에 대응하도록 형성된 브레이크 드럼(2A)의 쐐기형 마찰홈(2A-1) 양측 및 내측에 각각 공간부(2A-2), (2A-2'), (2A-3)를 형성하여서 된 것이다.The present invention, as shown in Figures 3 and 4, both sides and the inner side of the wedge-shaped friction groove (2A-1) of the brake drum (2A) formed to correspond to the wedge-shaped friction projection (5A-1) of the brake block (5A) The spaces 2A-2, 2A-2 ', and 2A-3 are respectively formed in the grooves.
이러한 구성의 본 고안은 탈수작동시에 회전하는 브레이크 드럼(2A)에서 블레이크 블럭(5A)이 분리됨은 종래와 동일하며, 탈수완료시에는 브레이크 블럭(5A)이 분리됨은 종래와 동일하며, 탈수완료시에는 브레이크 블럭(5A)의 쐐기형 마찰돌기(5A-1)가 브레이크 드럼(2A)의 쐐기형 마찰홈(2A-1)내로 삽입되며 마찰, 모터를 정지시키게 된다.(제3도에서 점선으로 도시됨)The present invention of such a configuration is the same as the conventional separation of the brake block (5A) from the brake drum (2A) that rotates during the dehydration operation, the separation of the brake block (5A) is the same as the conventional, when dehydration is completed, The wedge-shaped friction protrusion 5A-1 of the brake block 5A is inserted into the wedge-shaped friction groove 2A-1 of the brake drum 2A and stops the friction and the motor (shown in dashed lines in FIG. 3). being)
이때 직접마찰되는 쐐기형 마찰홈(2A-1)의 양측에 구비된 공간부(2A-2), (2A-2)는 마찰열에 의한 브레이크블럭(5A-1)의 마모를 최소화시키게 되고, 마찰시 발생되는 마찰소음도 공간부(2A-2), (2A-2')에서 상쇄되므로 현저한 소음저감효과를 얻게 된다.At this time, the space portions 2A-2 and 2A-2 provided on both sides of the wedge-shaped friction groove 2A-1 directly friction minimize the wear of the brake block 5A-1 due to the frictional heat and friction The friction noise generated at the time is also canceled in the spaces 2A-2 and 2A-2 ', so that a significant noise reduction effect is obtained.
또한 쐐기형 마찰홈(2A-1) 내측의 공간부(2A-3)도 마찰열 및 마찰소음을 저감시키게 되므로 마찰열에 의한 부품마모를 최대한 방지하고, 마찰에 의한 소음을 현저히 저감시켜 쾌적한 실내를 유지하며, 모터 정지시간을 단축하여 신속히 세탁을 끝낼수 있는 등의 여러가지 잇점이 있다.In addition, since the space portion 2A-3 inside the wedge-shaped friction groove 2A-1 also reduces frictional heat and frictional noise, it prevents wear of the components by frictional heat as much as possible and significantly reduces noise caused by friction to maintain a comfortable room. In addition, the motor stop time can be shortened and washing can be completed quickly.
