3 : 탈수조 4 : 세탁물3: dehydration tank 4: laundry

본 고안은 탈수시 발생되는 불 균형을 제거하는 진동제어 장치에 관한 것으로, 특히 장입된 액체가 운전상태에 따라 역류방지 밸브 작용으로 효율적인 균형을 잡는 세탁기의 액체 밸런스(Balancer)에 관한 것이다.The present invention relates to a vibration control device for removing an imbalance generated during dehydration, and more particularly, to a liquid balancer of a washing machine in which the charged liquid is efficiently balanced by a non-return valve function according to an operating state.

종래 세탁기 액체 밸런스 장치는 도면 제 5 도에 도시된 바와같이 탈수조 상면으로 고정형 리브(12)가 내설된 액체 밸런스 장치(11)를 설치하므로서, 탈수행정에 의한 탈수조(13)는 불균형을 초래하게 되고, 이때 상기액체 밸런스(11)내부에 액체는 원심력의 영향을 받게 되므로 세탁물(14)의 불균형 방향에 위치하면서 탈수조(13)의 불균형을 흡수케 되었다.In the conventional washing machine liquid balance device, as shown in FIG. 5, the liquid balance device 11 in which the fixed ribs 12 are installed on the upper surface of the dehydration tank is installed, and the dehydration tank 13 by the dehydration stroke causes an imbalance. At this time, the liquid inside the liquid balance 11 is affected by the centrifugal force, so that the imbalance of the dehydration tank 13 is absorbed while being positioned in the imbalance direction of the laundry 14.

그런데 작동하는 액체의 유동상태와 진동값은 가동시에는 고정형 리브(12)는 가동시에 순간적 액체 유동량을 효과적으로 조절할 수 없다는 단점을 지니게 되었다.However, the flow state and vibration value of the working liquid has the disadvantage that the fixed rib 12 during operation cannot effectively control the instantaneous liquid flow amount during operation.

이에 본 고안은 상기와 같은 단점을 해소하기 위하여, 액체 밸런스 장치(FB)내에 쉽게 구부러지는 힌지(2a)부위를 갖는 수지재질의 역류 방지 밸브(2)를 취부하여 운전상태에 따라 액체유동에 효과적으로 담수액의 유동이 많이 될수록 하여 원활하고 효율적인 진동 흡수로 안전성이 향상되도록 안출된 것으로, 그 실시예로 첨부된 예시도에 의거하여 구성 및 작용 효과를 상세히 설명하면 다음과 같다.In order to solve the above disadvantages, the present invention has a resin backflow prevention valve (2) having a hinge portion (2a) that is easily bent in the liquid balance device (FB) to effectively liquid flow in accordance with the operating conditions As the flow of fresh water increases, the smooth and efficient vibration absorption is devised to improve safety, and the construction and operation effects will be described in detail with reference to the accompanying drawings as an example.

본 고안은 세탁기의 탈수조(3)상면으로 장착되는 액체 밸런스(FB)내부에 다수의 역류방지 밸브(2)를 설치하고, 양측 연부에 쉽게 구부러지는 연성재질의 힌지(2a)와 담수에 의한 역류방지 밸브(2)의 휘어짐을 받쳐주는 스톱퍼(2b)를 부설하여 이루어진 구성을 갖는다.The present invention installs a plurality of non-return valves (2) in the liquid balance (FB) to be mounted to the upper surface of the dehydration tank (3) of the washing machine, and by the soft material hinge (2a) and fresh water that are easily bent on both sides It has the structure comprised by providing the stopper 2b which supports the bending of the backflow prevention valve 2. As shown in FIG.

이와같이 구성된 본 고안은 도면 제 1 도에 도시된 바와같이, 탈수행정에 의해 탈수조(3)가 회전하게 되면 내측에 위치한 세탁물(4)이 탈수되면서, 내측 임의의 위치로 세탁물(4)이 위치케될 경우 탈수조(3)에 불균형을 야기하게 되는데 이때, 액체 밸런스 장치(FB)는 세탁물(4)의 불균형력 반대방향 원심력이 작용케 되므로, 역류 방지 밸브(2)을 설치하여 기동, 정상, 정지시에 진동을 제어 하도록 한다.The present invention configured as described above, as shown in FIG. 1, when the dehydration tank 3 is rotated by the dehydration stroke, the laundry 4 located on the inside is dehydrated, and the laundry 4 is positioned at an arbitrary position inside. If the dehydration tank 3 is unbalanced, the liquid balance device (FB) acts as a centrifugal force in the opposite direction to the unbalanced force of the laundry (4). To control the vibration during stop.

역류방지 밸브(2)는 도면 제 2 도와 같이 한쪽에 "V"형 홈을 형성하며, 세탁기 탈수 가동시 탈수조(3)가 회전하면, 상부에 고정된 액체 밸런스가 같이 회전하게 되고, 정지해 있던 담수액은 관성에 의해서 탈수조(3)에 대해 회전 반대방향으로 "F"의 힘을 받으면 이때 역류방지 밸브(2)는 열리게 되면서 액체의 이동을 원활하게 하여 세탁물(4)의 불균형 반대편으로 쉽게 이동하여 진동을 억제한다. 회전수가 높아져서 정상 운전상태에서는 "F"의 힘을 받으면 스톱퍼 (2b)에 의해서 역류방지밸브(2)는 "│"자형이 유지됨으로써 액체유동이 없게되며, 역류방지밸브(2)는 복원력에 의하여 원형으로 회복되어 "│"자형을 유지하며 진동을 억제한다.The non-return valve 2 forms a "V" groove on one side as shown in FIG. 2, and when the dehydration tank 3 rotates when the washing machine is dewatered, the liquid balance fixed to the upper portion rotates together and stops. When the fresh water solution is inertia and receives a force of “F” in the opposite direction of rotation to the dehydration tank 3, the non-return valve 2 opens and smoothly moves the liquid to the opposite side of the laundry 4. Easily moved to suppress vibration. When the rotational speed is high and the normal operating state is subjected to the force of "F", the check valve 2b maintains the "│" shape by the stopper 2b so that there is no liquid flow, and the check valve 2 is restored by the restoring force. It is restored to a circular shape and keeps "│" shape and suppresses vibration.

탈수조(3)가 정지를 시작하면, 담수는 관성에 의해서 회전방향으로 역류방지 밸브(2)를 밀게 되나 이때는 스톱퍼(2b)에 의하여 역류방지밸브(2)가 움직이지 않아서 담수의 유동을 막게된다.When the dehydration tank 3 starts to stop, fresh water pushes the non-return valve 2 in the rotational direction by inertia, but at this time, the non-return valve 2 is not moved by the stopper 2b to prevent the flow of fresh water. do.

이와같이 본 고안에 의해 가동시에 내재된 담수가 일정방향으로만 유동하도록 함으로서, 진동을 효율적으로 흡수케하여 세탁기의 진동흡수 및 안전성을 보다 항상시킬 수 있는 효과가 있다.As such, by allowing the freshwater inherent in operation to flow only in a certain direction, the present invention has the effect of efficiently absorbing vibrations, thereby making the vibration absorption and safety of the washing machine more constant.
