본 고안은 전자동 전기세탁기에 관한 것으로서 특히 탈수 기능시에 탈수조의 자체 균형조정을 위한 세탁기의 액체 평형장치에 관한 것이다.The present invention relates to a fully automatic electric washing machine, and more particularly to a liquid balancer of a washing machine for self-balancing of the dehydration tank in the dehydration function.

세탁기의 탈수 기능은 측면과 바닥면에 단수의 탈수공이 천공 설치된 탈수조를 고속으로 회전시켜 줌으로서 발생하는 원심력에 의해 세탁물내에 함유되어 있는 수분을 제거하도록 한 것이다.The dehydration function of the washing machine is to remove the water contained in the laundry by centrifugal force generated by rotating the dehydration tank installed with a single dehydration hole on the side and the bottom at high speed.

이와 같은 탈수 기능시 내부의 세탁물이 일측에 치우쳐 있게 되면 탈수조의 중심 균형이 맞지 않게 되어 편심되게 회전하게 된다.When the laundry inside the dehydration function is biased to one side, the center balance of the dehydration tank is not balanced, and the laundry is eccentrically rotated.

이와 같은 문제점을 개선하기 위하여 탈수조의 상부 둘레에 액체를 장입시켜 자체 균형을 유지하도록 하는 방법이 사용되고 있다.In order to improve this problem, a method of charging a liquid around the upper part of the dehydration tank to maintain its own balance has been used.

이와같은 종래의 기술은 첨부도면 제3도에 도시된 바와 같이 탈수조(10)의 상부 둘레에 액체평형조(200)를 형성하고 내부의 외벽으로 부터 원주면에 수직하게 다수개의 리브(210)를 형성하여 외측은 칸막이가 되도록 하되 내측은 서로 통할 수 있도록 절개 형성 하였다.This conventional technique forms a liquid balance tank 200 around the top of the dewatering tank 10 as shown in FIG. 3 of the accompanying drawings, and a plurality of ribs 210 perpendicular to the circumferential surface from the outer wall of the interior. By forming the outer side to be partitions, but the inner side was formed to cut through each other.

이와 같이 형성된 액체평형조(200)내에 적정량의 액체를 투입하여 줌으로서 탈수조(10)의 작동시 불균형 편심에 의한 진동을 완화시켜 준다.The liquid is added to the liquid balance tank 200 formed as described above to reduce the vibration caused by the unbalanced eccentricity during operation of the dehydration tank 10.

그러나 종래의 이와 같은 형상의 평형장치는 액체평형조(200)내의 칸막이 리브(210)에 의해 액체 유동에 장애가 되어 순간적인 대응 기능이 원활하지 못한 문제점이 있었다.However, the conventional balancer of such a shape has a problem that the instantaneous response function is not smooth due to obstacles to the liquid flow by the partition rib 210 in the liquid balance tank 200.

작동하는 액체의 유동상태와 진동값은 기동시에 액체의 유동이 많을 수록 세탁조의 진동이 저감되고, 정상 및 정지시에는 액체의 유동이 적을수록 진동이 저감되는 관계가 있기 때문에 상기의 액체평형장치에서는 액체평형조(200)내에 형성된 수의 칸막이 리브(210)에 의해 기동시 순간적인 액체 유동을 저해하므로서 확실한 평형기능이 이루어 지지 않으며 정상 및 정지시에도 내부에서 효과적인 액체유동을 제어하지 못한다.The liquid leveling device and the vibration value of the working liquid have a relationship that the more the fluid flows at the start, the lower the vibration of the washing tank, and the less the flow of the liquid at the time of normal and stop, the lower the vibration. The number of partition ribs 210 formed in the liquid balance tank 200 inhibits instantaneous liquid flow during start-up and thus does not achieve a reliable equilibrium function and does not control effective liquid flow therein even during normal and stop.

또 다른 종래기술은 액체평형조내를 2중 또는 3중의 환형리브에 의해 각각 분리되도록 형성한뒤 각 공간마다 별도로 액체를 분리 투입시켜 평형기능이 이루어 지도록 하였으나 이 역시 효과적인 평형기능을 수행하지는 못하였다.Another prior art is to form the liquid balance tank to be separated by a double or triple annular rib, respectively, and to separate the liquid into each space to achieve the equilibrium function, but this also did not perform an effective equilibrium function.

이와 같은 종래의 문제점을 개선하기 위하여 안출된 본 고안에서는 액체평형조 내부가 전체적으로 서로 통할 수 있도록 하되 액체의 흐름을 조절 할 수 있도록 하여서 된 세탁기의 액체 평형장치를 제공하는데 그 목적이 있다.The present invention devised to improve such a conventional problem is to provide a liquid balancer of the washing machine by allowing the inside of the liquid balance tank to communicate with each other as a whole to control the flow of the liquid.

상기의 목적을 달성하기 위하여 본 고안에서는 액체평형조내에 여러개의 흐름방향 전환용 리브를 형성시켜 준뒤 액체평형조내부의 공간이 전체적으로 통할 수 있도록 하며 상기 리브는 원주의 방향에 준해서 일측 방향 즉 탈수기능시 탈수조의 회전방향으로 비스듬히 경사부를 형성하여 기동시 순간적인 대응 기능이 이루어질 수 있도록 하며, 정상작동시나 정지 기능시에도 액체의 유동을 줄여주어 진동을 저감시키도록 함을 특징으로 한다.In order to achieve the above object, in the present invention, a plurality of flow direction switching ribs are formed in the liquid balancing tank so that the space inside the liquid balancing tank can be generally passed through the ribs in one direction or dehydration according to the circumferential direction. When it is functioning, the inclined portion is formed obliquely in the rotational direction of the dehydration tank so that the instantaneous response function can be achieved at the start, and the vibration is reduced by reducing the flow of liquid even during the normal operation or the stop function.

이하 첨부된 도면에 의거하여 본 고안을 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

세탁기의 탈수조(10)의 상단 주연에 액체(120)가 주입될 수 있도록 형성된 액체평형조(200)가 구비되며, 상기 액체평형조(100)내에는 내부에 주입된 액체(120)의 흐름방향 전환이 용이하게 이루어 질 수 있도록 일측 방향성을 가지며 일측부분이 비스듬히 경사지게 형성된 경사부(111)를 갖는 다수의 리브(110)가 부설된다.The liquid balance tank 200 is formed so that the liquid 120 can be injected into the upper periphery of the dehydration tank 10 of the washing machine, and the liquid 120 injected into the liquid balance tank 100 flows therein. In order to easily change the direction, a plurality of ribs 110 having an inclination portion 111 having one side direction and having one side portion obliquely inclined are laid.

즉 상기 다수의 리브(110) 일측 경사부(111)는 탈수기능시 탈수조(10)의 회전방향쪽 부분이 바깥쪽으로 휘어진 상태의 동일 회전방향성을 갖도록 형성된다.That is, the plurality of ribs 110, one side inclined portion 111 is formed to have the same direction of rotation in a state in which the rotational direction portion of the dehydration tank 10 is bent outward during the dehydration function.

이러한 리브(110)는 액체평형조(100)내에 주입되어 탈수기능시에 탈수조(10)의 회전가속도에 의하여 발생되는 관성력에 의해 발생되는 액체(120)의 흐름방향을 조절하여 주는 중요한 기능을 한다.The ribs 110 are injected into the liquid balance tank 100 to control the flow direction of the liquid 120 generated by the inertial force generated by the rotational acceleration of the dehydration tank 10 during the dehydration function. do.

상기 액체평형조(100)의 바닥면(101)은 안쪽이 깊게 경사면을 이루도록 형성되어 있다.The bottom surface 101 of the liquid balance tank 100 is formed to form an inclined surface deep inside.

이와 같은 액체평형조(100)는 상부에도 동일형상의 리브가 형성된 덮개(102)가 밀폐 접착되어 있다.In the liquid balance tank 100, a lid 102 having ribs of the same shape is formed on the upper portion of the liquid balance tank 100.

이와 같이 구성된 본 고안의 작용 및 효과를 상세히 살펴보면 전자동 세탁기의 탈수행정에 의해서 탈수조(10)가 회전하게 되면 원심력에 의해서 내부에 담겨진 세탁물(20)에 함유된 수분이 이탈된다.Looking at the action and effect of the present invention configured as described above in detail when the dehydration tank 10 is rotated by the dehydration stroke of the automatic washing machine, the moisture contained in the laundry 20 contained therein by the centrifugal force is released.

그러나 내부의 세탁물(20)이 일측에 치우쳐 있게되면 탈수조(10)는 불균형력을 일으켜 매우 진동이 심하게 일어 나며 이때 액체평형조(100)내에서 액체(120)가 상기 불균형력에 반대방향으로 완화시켜주는 원심력이 작용하게 되어 평형상태를 유지하게 된다.However, when the laundry 20 inside is biased to one side, the dehydration tank 10 causes an imbalance force, which causes the vibration to be very severe. At this time, the liquid 120 in the liquid balance tank 100 is opposite to the imbalance force. The centrifugal force acts to relieve and maintains equilibrium.

즉 액체평형조(100)의 바닥면(101)이 안쪽으로 경사져 있으므로 정지시에 안쪽에 몰려있던 액체(120)가 탈수조(10)의 회전에 따라 바깥쪽으로 벗어나려는 원심력이 작용되게 되며, 또한 액체(120)의 관성에 의해 정지하려는 성질과 탈수조(10)와 함께 회전하는 액체평형조(100)내의 각 리브(110)에 의해 액체의 상대적 흐름방향이 계속적으로 바뀌면서 원심력이 각 리브(110)에 전달되게 된다.That is, the bottom surface 101 of the liquid balance tank 100 is inclined inward, so that the centrifugal force that the liquid 120 collected in the interior at the time of stopping stops outwards due to the rotation of the dehydration tank 10, and also The relative flow direction of the liquid is continuously changed by each rib 110 in the liquid balance tank 100 which rotates with the dehydration tank 10 and the property to be stopped by the inertia of the liquid 120, so that the centrifugal force is changed to each rib 110. Will be delivered).

특히 상기 리브(110)의 일측방향으로 형성된 경사부(111)에 의하여 회전 가속시에 액체(120)을 액체평형조(100)의 안쪽으로 모아지도록 하여주는 작용과 동시에 회전에 의한 액체 자체의 원심력이 작용됨으로서 불균형이 조정된다.In particular, by the inclined portion 111 formed in one direction of the rib 110, the liquid 120 is collected into the liquid balance tank 100 during rotational acceleration, and at the same time, the centrifugal force of the liquid itself by rotation. By this action the imbalance is adjusted.

탈수조(10)가 정지시에는 액체(120)의 유동이 없이 액체평형조(100)의 안쪽에 위치하고 있게되며 기동시 즉, 간헐탈수시에는 액체의 유동이 안쪽에서 적게 이루어진다.When the dehydration tank 10 is stopped, the liquid balance tank 100 is located inside the liquid balance tank 100 without the flow of the liquid 120. When the dehydration tank 10 is started, that is, when the intermittent dehydration is performed, the flow of the liquid is less.

그러나 회전속도가 빨라져 갈수록 액체의 원심력이 커져 다수 리브의 각부분에 작용되어 유동하면서 불균형력을 흡수하게 된다.However, as the rotational speed increases, the centrifugal force of the liquid increases, acting on each part of the plurality of ribs to absorb the imbalance force while flowing.

이상 살펴본 바와 같이 본 고안에서는 액체평형장치내의 각 리브가 일측방향(탈수조의 회전방향)으로 경사부를 형성하여 구성시킴으로서 액체의 흐름방향을 계속 안쪽으로 모아지도록 하며 동시에 원심력에 의하여 액체가 바깥쪽으로 벗어나려는 힘에 의하여 적은량의 액체에 의해서도 커다란 힘이 발생되어 불균형력에 대항하므로서 탈수작업시 탈수조의 진동을 최소화 할 수 있는 매우 유용한 고안인 것이다.As described above, in the present invention, each rib in the liquid balancer forms an inclined portion in one direction (rotation direction of the dewatering tank) so that the flow direction of the liquid continues to be collected inward, and at the same time, the liquid is forced out of the liquid by centrifugal force. It is a very useful design that can minimize the vibration of the dehydration tank during the dehydration operation by counteracting the imbalance force generated by a large force even by a small amount of liquid.
