한편, 본 발명에 따라 내부에 펠트(20)가 설치되고, 상기 펠트(20)에 항상 윤활제로서 오일 또는 그리스가 함침되어 있는 드럼세탁기의 댐퍼 핀(10)의 경우, 드럼세탁기가 가동 중 드럼세탁기 내의 온도가 올라감에 따라 댐퍼 핀의 온도도 올라가게 되어 오일 또는 그리스가 댐퍼 핀(10)의 몸통부(11) 표면으로 도포가 되어 소음이나 마모 저감의 효과를 가져올 수 있게 된다.On the other hand, in the case of the damper pin 10 of the drum washing machine in which the felt 20 is installed therein and the oil is always impregnated with oil or grease as the lubricant, the drum washing machine is in operation. As the temperature inside increases, the temperature of the damper pin also increases, so that oil or grease is applied to the surface of the body portion 11 of the damper pin 10 to reduce noise or wear.

반대로, 드럼세탁기의 가동을 중지시키면 온도가 낮아지게 되므로 댐퍼 핀(10)의 몸통부(11) 표면으로 도포된 오일이나 그리스가 다시 펠트(20)로 흡수되어, 필요 없이 오일 및 그리스가 사용되는 것을 방지할 수 있게 된다.On the contrary, since the temperature is lowered when the drum washing machine is stopped, oil or grease applied to the surface of the body portion 11 of the damper pin 10 is absorbed back into the felt 20, so that oil and grease are not used. Can be prevented.

이와 같이, 고정홀(81) 및 삽입홀(51)의 내면과 댐퍼 핀(10) 사이에 항상 윤활제가 보충되도록 함으로써, 댐퍼 핀(10) 내부의 유격소음을 방지할 수 있게 되며, 또한, 댐퍼 핀(10) 및 댐퍼 핀(10)과 접하게 되는 구성요소들의 마모를 줄일 수 있게 된다. In this way, the lubricant is always replenished between the inner surface of the fixing hole 81 and the insertion hole 51 and the damper pin 10, thereby preventing the play of noise inside the damper pin 10, and the damper. It is possible to reduce wear of the components coming into contact with the pin 10 and the damper pin 10.

이제까지 본 발명에 대하여 그 바람직한 실시예를 중심으로 살펴 보았으나, 본 발명이 속하는 기술분야에서 통상의 지식을 가진 자는 본 발명의 본질적 기술 범위 내에서 변형된 형태의 또 다른 실시예를 구현할 수 있을 것이다.So far, the present invention has been described with reference to the preferred embodiments, but those skilled in the art to which the present invention pertains may implement another embodiment of a modified form within the essential technical scope of the present invention. .

상기에서와 같이, 본 발명은 댐퍼와 캐비닛을 연결하는 댐퍼 핀의 구조를 개선하여, 시간이 지남에 따라 댐퍼 핀이 헐거워지게 되는 것을 방지하며, 윤활제가 적절히 사용되도록 함으로써 소음 및 마모를 줄일 수 있게 되는 효과가 있다.As described above, the present invention improves the structure of the damper pin connecting the damper and the cabinet, to prevent the damper pin from loosening over time, and to reduce noise and wear by allowing the lubricant to be used properly It is effective.
