본 발명은 세탁기에 관한 것으로서, 더욱 상세하게는 세탁기의 높낮이를 자동으로 조절하여 수평을 맞추는 수평조절레그 및 이를 구비한 세탁기에 관한 것이 다. The present invention relates to a washing machine, and more particularly, to a leveling leg for automatically adjusting the level of the washing machine to level the washing machine and a washing machine having the same.

세탁기는 일반적으로 육면체 형상을 가지며, 네 모서리에 지면과 연결시킬 수 있는 레그가 장착된다. 레그는 통상 볼트 방식으로 되어 있어 일방향으로 회전시킬 경우 길이가 연장되고 타방향으로 회전시킬 경우 길이가 단축됨으로써 세탁기의 높낮이 및 수평을 맞추도록 되어 있다. 하지만, 이러한 세탁기의 레그는 협소한 공간이나 노약자의 경우 높낮이 및 수평을 정확히 맞추기가 용이하지 않은 문제점이 있었다. Washing machines generally have a hexahedron shape and are equipped with legs that connect to the ground at four corners. Legs are usually bolted, so that the length is extended when rotated in one direction and the length is shortened when rotated in the other direction so that the height and level of the washing machine are leveled. However, the legs of such a washing machine has a problem that it is not easy to accurately raise the height and level in a narrow space or the elderly.

이에, 최근에는 사용자가 수동으로 높낮이를 조절하지 않아도 되는 자동높이 조절 레그가 시판되고 있다. 통상 이러한 자동높이조절 레그는 내부에 스프링을 개재하여 세탁기의 자중에 의해 스프링이 압축됨으로써 세탁기의 수평을 맞추는 것이다.Therefore, recently, an automatic height adjustment leg has been commercially available, which does not require the user to manually adjust the height. Typically, such automatic height adjustment leg is to level the washing machine by the spring is compressed by the weight of the washing machine through the spring therein.

하지만, 상기와 같은 종래 기술은 예를 들어, 세탁물이 편심된 상태로 탈수 되는 경우, 내부 스프링이 오히려 진동을 증폭시키기 때문에 세탁기에 과도한 진동을 전달하는 문제점이 있었다. 또한, 다른 종래 기술로서 내부 스프링의 과도한 진동이 세탁기로 전달되는 것을 방지하기 위해 완충띠, 마찰재와 같은 댐핑부재를 내부에 마련한 자동높이조절 레그도 있었으나, 댐핑부재는 진동을 어느 정도 저감시킬 뿐 수평이 맞추어진 레그를 세탁기에 고정시키는 데는 한계가 있었다.However, the prior art as described above, for example, when the laundry is dehydrated in an eccentric state, there is a problem of transmitting excessive vibration to the washing machine because the inner spring rather amplifies the vibration. In addition, as another conventional technique, there was an automatic height adjustment leg provided with a damping member such as a buffer band and a friction material therein to prevent excessive vibration of the inner spring from being transmitted to the washing machine, but the damping member only reduces the vibration to some extent. There was a limit to fixing this fitted leg to the washing machine.

본 발명은 상술한 종래기술의 문제점들을 해결하기 위한 것으로, 본 발명의 목적은 세탁기 설치시에는 자동으로 높낮이를 조절하여 수평을 맞추고 설치 후에는 조절된 수평이 견고히 고정되는 수평조절레그 및 이를 구비한 세탁기를 제공하는 데 있다.
