본 발명은 드럼세탁기의 댐퍼 연결구조에 관한 것으로, 더욱 상세하게는 댐퍼가 드럼세탁기의 하부면에 연결됨에 있어서, 스프링 구조가 적용됨으로 전후 방향과 좌우 방향의 움직임에 자유도를 부가한 드럼세탁기의 댐퍼 연결구조에 관한 것이다.The present invention relates to a damper connection structure of a drum washing machine, and more particularly, in the damper is connected to the lower surface of the drum washing machine, the spring structure is applied to the damper of the drum washing machine to add freedom to the movement in the front and rear and right and left directions. It relates to the connection structure.

일반적으로 드럼 세탁기는 드럼의 안쪽에 물과 세제와 빨래를 넣고 수평축으로 저속 회전시켜 빨래가 리프트에 의해 올려졌다 낙하하는 충격에 의해 세탁이 이루어지게 되며, 이로 인하여 세탁물의 꼬임 및 손상이 거의 없을 뿐만 아니라 물을 적게 사용할 수있는 장점이 있는 세탁기이다.In general, the drum washing machine puts water and detergent and laundry inside the drum and rotates at a low speed on the horizontal axis to wash the laundry by a lift. But it is a washing machine with the advantage of using less water.

상기와 같은 드럼세탁기의 진동 방지를 위하여 코일스프링 방식과 마찰부재를 이용한 마찰 방식의 댐퍼가 사용된다.In order to prevent the vibration of the drum washing machine as described above, a damper of a friction type using a coil spring method and a friction member is used.

이하 도면을 참조하여 종래 드럼세탁기의 댐퍼 연결구조를 설명하기로 하며, 도 1은 종래 드럼세탁기의 측단면도이며, 도 2는 종래 드럼세탁기에 사용되는 댐퍼의 측단면도이다.Hereinafter, a damper connection structure of a conventional drum washing machine will be described with reference to the drawings. FIG. 1 is a side cross-sectional view of a conventional drum washing machine, and FIG. 2 is a side cross-sectional view of a damper used in a conventional drum washing machine.

드럼세탁기는 캐비닛(1)내에 설치된 터브(3)와, 상기 터브(3) 내에 세탁물을 담을 수 있도록 설치된 드럼(5)을 포함하여 구성된다.The drum washing machine includes a tub 3 installed in the cabinet 1 and a drum 5 installed to hold laundry in the tub 3.

상기 터브(3)의 상부를 지지하는 스프링(7)은 상기 캐비닛(1)과 터브(3) 사이에 탄성을 지니며 설치된다.A spring 7 supporting the top of the tub 3 is installed with elasticity between the cabinet 1 and the tub 3.

그리고, 상기 터브(3)의 하부와 캐비닛(1) 사이에 설치된 댐퍼(9)는 상기 터브(3)의 하측을 지지함과 동시에, 터브(3)의 진동폭을 줄이는 동작도 하게 된다.In addition, the damper 9 provided between the lower portion of the tub 3 and the cabinet 1 supports the lower side of the tub 3 and also reduces the vibration width of the tub 3.

상기 댐퍼(9)는 도 2에 도시된 바와 같이, 파이프 형상으로 터브(3)의 외주면에 결합되며 일측이 개방된 튜브(11)와, 상기 개방된 튜브(11)의 내측으로 삽입되고 타단은 튜브(11) 외측으로 연장되어 터브(3)의 진동에 의해 왕복 운동하도록 캐비닛(1)에 결합된 로드(9)와, 튜브(11)의 내측과 피스톤(15)의 외측 사이에 설치되어 터브(3)의 진동 진폭을 저감시키도록 마찰력을 발생시키는 마찰부재(19)로 구성되어 진다.As shown in FIG. 2, the damper 9 is coupled to the outer circumferential surface of the tub 3 in a pipe shape and is inserted into an inner side of the open tube 11 and the other end of which is opened on one side thereof. A rod 9 coupled to the cabinet 1 so as to extend outside the tube 11 and reciprocate by vibration of the tub 3, and installed between the inside of the tube 11 and the outside of the piston 15, And a friction member 19 for generating a frictional force to reduce the vibration amplitude of (3).

상기 피스톤(15)의 하단에는 연결구멍이 형성된 하부연결부재(20)가 설치되며, 상기 하부연결부재(20)는 캐비닛(1)의 하부면(22)으로 부터 돌출 형성된 고정편(24)에 볼트(26) 체결되어 일방향으로만 회전 가능한 상태로 설치된다.A lower connection member 20 having a connection hole is installed at a lower end of the piston 15, and the lower connection member 20 is provided on a fixing piece 24 protruding from the lower surface 22 of the cabinet 1. The bolt 26 is fastened and installed in a state capable of rotating only in one direction.

이러한 구조의 드럼세탁기는 세탁물을 드럼(5) 내에 넣은 다음 드럼세탁기에 전원을 인가하면 세탁수가 터브(3) 내에 유입되어지고, 세탁수가 일정량 유입되면 드럼(5)이 회전하면서 세탁물을 세탁하게 된다. The drum washing machine having such a structure puts laundry into the drum 5 and then applies power to the drum washing machine so that washing water flows into the tub 3, and when a certain amount of washing water flows, the drum 5 rotates to wash the laundry. .

그리고 세탁물의 세탁이 완료되면 세탁물의 탈수가 이루어진다.And when the washing of the laundry is completed, the laundry is dewatered.

이때, 세탁 또는 탈수 과정이 진행되면서 발생하는 터브(3)와 드럼(5)의 진 동이 댐퍼(9)에 전달된다.At this time, the vibration of the tub (3) and the drum (5) generated during the washing or dehydration process is transmitted to the damper (9).

댐퍼(9)에서는 터브(3)의 진동 진폭에 의해 튜브(11)내측을 피스톤(15)이 왕복운동하면서 마찰부재(10)의 마찰력에 의해 터브(3)의 진동 진폭이 저감되어 진다.In the damper 9, the vibration amplitude of the tub 3 is reduced by the frictional force of the friction member 10 while the piston 15 reciprocates inside the tube 11 due to the vibration amplitude of the tub 3.

그러나, 종래 기술에 따른 드럼세탁기의 댐퍼 연결구조는 세탁물의 편심 등에 의한 터브(3)의 불균형 상태가 초래될 경우, 상기 터브(3)는 3차원으로 진동을 하게 되나, 상기 댐퍼(9)의 하단은 볼트(26)에 의하여 하부면(22)에 일방향으로만 회전 가능한 상태로 설치되어, 상기 터브(3)의 3차원 진동을 감쇠시키는 데에 한계가 있으며, 이로 인하여 터브(3)의 진동이 하부면(22)으로 전달되어 드럼세탁기 전체가 움직이게 됨으로 안전성이 저하되는 문제점이 발생된다.However, in the damper connection structure of the drum washing machine according to the prior art, when the imbalance of the tub 3 is caused by the eccentricity of the laundry, the tub 3 vibrates in three dimensions, but the damper 9 The lower end is installed on the lower surface 22 by the bolt 26 in a state capable of rotating only in one direction, thereby limiting attenuation of the three-dimensional vibration of the tub 3, which causes vibration of the tub 3. The lower surface 22 is transferred to the entire drum washing machine is a problem that the safety is lowered.

상기 열거된 종래 문제점을 해결하기 위한 본 발명의 목적은, 터브의 전후측 이동 뿐만 아니라 좌우측 이동도 감쇄할 수 있는 드럼세탁기의 댐퍼 연결구조를 제공하는 것이다.
