Description

세탁기의 발란스링Balance ring of washing machine

본 고안은 세탁기의 발란스링에 관한 것으로 더욱 상세하게는 세탁기의 상부에 장착된 상부발란스링이 탈수 초기시 세탁조의 회전원심력에 의해 세탁조의 외곽으로 위치이동하도록 하여 탈수 초기시 발생하는 세탁조의 언발란스를 신속하면서도 보다 효과적으로 잡아줄 수 있도록 하여 탈수시의 언발란스로 인한 세탁조 및 저수조의 파손을 방지할 수 있도록 한 세탁기의 발란스장치에 관한 것이다.The present invention relates to a balancing ring of a washing machine, and more particularly, the upper balance ring mounted on the upper part of the washing machine moves the position of the washing tank to the outside of the washing tank by the rotational centrifugal force of the washing tank at the initial stage of dehydration. The present invention relates to a balance device for a washing machine that can be quickly and more effectively to prevent damage to a washing tank and a storage tank due to unbalance during dehydration.

일반적으로 전자동 세탁기는 급수, 세탁, 헹굼, 배수 및 탈수행정을 설정된 프로그램에 의해 순차적으로 수행하여 세탁물을 세탁하도록 구성되어 있는 것으로서, 세탁이 완료된 세탁물을 탈수시켜 주기 위해서는 구동부의 클러치 작용에 의해 회전익을 상태에서 구동부를 구동시켜 주면 세탁조가 일방향으로 고속회전되어 발생된 회전원심력에 의하여 세탁물에 포함된 세탁수가 탈수되는 것이다.In general, the automatic washing machine is configured to wash laundry by sequentially performing water supply, washing, rinsing, draining, and dehydrating strokes by a set program. In order to dehydrate laundry after washing, the rotary blade is driven by a clutch action of the driving unit. When the driving unit is driven in a state, the washing tank is dewatered by the rotation centrifugal force generated by the high-speed rotation in one direction.

한편, 종래의 세탁기에 있어서는 세탁조의 하부는 그 중앙에 저수조를 관통한 탈수축이 결합되어, 탈수 행정시 상기 탈수축에 의해 세탁조가 고속회전하게 되는 것이며 이렇게 고속회전되는 세탁조는 그 하부의 중앙을 중심으로 하여 회전됨에 따라 세탁조의 회전원심력이 하부로부터 상부로 전달되어 세탁조의 상부 회전반경이 커짐에 따라 이의 언발란스를 잡아주기 위해 첨부된 도면의 도 1에 도시된 바와 같이 세탁조(100)의 상단부에 염수(130)가 담겨져 있는 발란스링(120)이 장착되게 된다.On the other hand, in the conventional washing machine, the lower part of the washing tank is coupled to the dehydration shaft passing through the reservoir tank at the center thereof, so that the washing tank is rotated at high speed by the dehydration shaft during the dehydration stroke. Rotational centrifugal force of the washing tub is transmitted from the bottom to the upper portion as it is rotated about the center, and as shown in FIG. 1 of the attached drawing to hold the unbalance thereof as the upper rotating radius of the washing tub increases, The balance ring 120 containing the brine 130 is to be mounted.

그러나 상기 발란스링(120)은 그 내부의 체적이 크고 이에 담수되는 염수(130)의 양이 많을수록 언발란스의 보정효율이 증대되는 것이지만 발란스링(120)이 세탁조(100) 상부의 협소한 공간에 장착되기 때문에 발란스링(120)의 크기가 제한적일 수 밖에 없는 것이다.However, the balance ring 120 has a large volume therein, and the larger the amount of the brine 130 is, the more the correction efficiency of the unbalance is increased, but the balance ring 120 is mounted in a narrow space above the washing tank 100. Because of this, the size of the balancing ring 120 is bound to be limited.

따라서 그 내부공간에 담겨지게 되는 염수(130)의 담수량이 적을 수 밖에 없어 탈수 초기에 발생하는 세탁조(100)의 언발란스를 효과적으로 잡아주지 못하게 되는 문제점이 있었다.Therefore, the amount of fresh water of the brine 130 to be contained in the internal space can not be less there is a problem that can not effectively catch the unbalance of the washing tank 100 occurs in the early stage of dehydration.

이에 본 고안은 상기의 제반 문제점을 해소시키기 위해 안출된 것으로 본 고안은 탈수 초기시 발생하는 세탁조의 언발란스를 신속하면서도 보다 효과적으로 잡아줄 수 있도록 하여 탈수시의 언발란스로 인한 세탁조 및 저수조의 파손을 방지할 수 있도록 한 세탁기의 발란스링을 제공하는데 그 목적이 있는 것이다.Therefore, the present invention was devised to solve the above problems, and the present invention can quickly and more effectively catch the unbalance of the washing tank generated at the initial stage of dehydration, thereby preventing damage to the washing tank and the storage tank due to unbalance during dehydration. The purpose is to provide a balancing ring of a washing machine.

상기의 목적을 달성시키기 위한 본 고안에 따른 세탁기의 발란스링은 세탁조의 상부둘레에 발란스링을 장착시키되, 상기 발란스링은 세탁조의 상부에 결합되는 하부발란스링과; 상기 하부발란스링의 상부에 형성된 공간부내에 외측방향으로 슬라이드 가능하게 결합되어진 상부발란스링으로 구성되어지되, 상기 하부발란스링의 공간부내에 수용되어진 상부발란스링은 공간부의 내측으로부터 연결되어진 인장스프링에 의해 세탁조의 내측방향으로 인장되어진 상태로 결합되어 세탁기의 초기 탈수시 상기 상부발란스링이 세탁조의 회전원심력에 의해 상기 인장스프링의 인장력을 극복하면서 세탁조의 외측으로 위치이동되어 세탁조의 언발란스가 순간적으로 잡혀지도록 한 것에 그 특징이 있는 것이다.The balance ring of the washing machine according to the present invention for achieving the above object is equipped with a balance ring on the upper circumference of the washing tank, the balance ring is a lower balance ring coupled to the upper portion of the washing tank; The upper balance ring is slidably coupled outwardly in the space formed on the upper portion of the lower balance ring, the upper balance ring accommodated in the space portion of the lower balance ring is connected to the tension spring connected from the inside of the space portion. The upper balance ring is moved to the outside of the washing tank while overcoming the tension spring by the centrifugal force of the washing tank when the initial dehydration of the washing machine is combined.

상기 하부발란스링(160)의 공간부(180)는 도 3에 도시된 바와 같이 소정의 배치간격을 두고 형성되어진 벽체(140)에 의해 4등분으로 분할 구성되어 그 내부에 상부발란스링(150)가 세탁조(100)의 외곽방향으로 위치이동할 수 있도록 구성된 것이다.As shown in FIG. 3, the space portion 180 of the lower balance ring 160 is divided into four portions by a wall 140 formed at predetermined intervals, and the upper balance ring 150 is formed therein. Is configured to be moved in the outer direction of the washing tub (100).

한편, 상기 상·하부발란스링(150)(160)의 공간부내에는 염수(130)가 각각 담수되는 것이며, 이렇게 상·하부발란스링(150)(160)에 담수되어진 염수(130)는 상부발란스링(150)내의 공간에 담수되어진 것이 하부발란스링(160)에 담수된 것보다 그 비중이 높도록 함으로서 세탁조(100)의 언발란스를 효과적으로 잡아줄 수 있도록 하는 것이 바람직하다.On the other hand, the brine 130 is fresh water in the space portion of the upper and lower balance ring 150, 160, respectively, the salt water 130 is soaked in the upper and lower balance ring 150, 160 is the top balance It is preferable to effectively hold the unbalance of the washing tub 100 by allowing the specific gravity of the fresh water in the space in the ring 150 to be higher than that of the fresh water in the lower balance ring 160.

상기와 같이 구성되어진 본 고안은 탈수행정시 세탁조(100)의 회전속도가 증가하게 되면 발생된 원심력에 의해 하부발란스링(160)의 공간부(180)내에 수용되어진 상부발란스링(150)이 인장스프링(170)의 인장력을 극복하면서 세탁조(100)의 외곽으로 밀려나게 된다.According to the present invention, the upper balance ring 150 accommodated in the space portion 180 of the lower balance ring 160 by the centrifugal force generated when the rotational speed of the washing tank 100 increases during dehydration administration is tensioned. Overcoming the tension of the spring 170 is pushed to the outside of the washing tub (100).

상기와 같이 상부발란스링(150)이 세탁조(100)의 회전원심력에 의해 세탁조(100)의 외곽으로 위치이동되면 그 내부에 담수된 염수(130)의 작용에 의해 무게중심이 세탁조(100)의 외곽방향으로 이동됨으로서 회전진동이 크게 발생되는 세탁조(100) 상부방향의 언발란스가 효과적으로 잡혀지게 되는 것이다.As described above, when the upper balance ring 150 is moved to the outside of the washing tank 100 by the rotational centrifugal force of the washing tank 100, the center of gravity of the washing tank 100 is caused by the action of the brine 130 freshened therein. By moving in the outward direction, the unbalance of the upper direction of the washing tub 100, which is largely caused by rotational vibration, is effectively caught.

한편, 탈수행정이 완료되어 세탁조(100)의 회전이 서서히 멈추어지게 되면 세탁조(100)의 원심력이 발생되지 않게 되어 세탁조(100)의 외곽방향으로 밀려나 있던 상부발란스링(150)가 인장스프링(170)의 인장력에 의해 세탁조(100)의 내측방향으로 복귀되는 것이다.On the other hand, when the dehydration stroke is completed and the rotation of the washing tank 100 is slowly stopped, the centrifugal force of the washing tank 100 is not generated, so that the upper balance ring 150 pushed in the outer direction of the washing tank 100 is the tension spring 170. It is to be returned to the inner direction of the washing tank 100 by the tensile force of the).

본 고안은 세탁조의 외주둘레에 발란스링을 장착시키되, 상기 발란스링은 세탁조의 상부에 결합되는 하부발란스링과; 상기 하부발란스링의 상부에 형성된 공간부내에 세탁조의 외측방향으로 위치이동할 수 있도록 결합된 상부발란스링으로 구성되어 상기 상부발란스링이 세탁기의 탈수시 세탁조의 회전원심력에 의해 세탁조의 외측으로 위치이동하면서 세탁조의 언발란스가 잡혀지도록 함으로서 세탁조의 언발란스를 보다 효과적으로 잡아줄 수 있어 탈수시의 언발란스로 인한 세탁조 및 저수조의 파손을 방지할 수 있는 효과가 있는 것이다.The present invention is equipped with a balance ring on the outer circumference of the washing tank, the balance ring is a lower balance ring coupled to the upper portion of the washing tank; The upper balance ring is configured to be coupled to move in the outward direction of the washing tank in the space formed on the upper portion of the lower balance ring, the upper balance ring is moved to the outside of the washing tank by the centrifugal force of the washing tank when the washing machine dewatered By being able to catch the unbalance of the washing tank can more effectively hold the unbalance of the washing tank has the effect of preventing the breakage of the washing tank and the storage tank due to unbalance during dehydration.
