세탁기의 댐퍼 체결 구조Damper fastening structure of washing machine

본 발명은 드럼 세탁기에 있어서 세탁조의 진동을 줄이기 위한 댐퍼(15)의 체결 구조에 관한 것으로서, 특히 댐퍼 핀을 사용함으로서, 종래의 볼트 체결 구조에서 발생되는 볼트 풀림 등의 문제를 해결하는 댐프 체결 구조에 관한 것이다.The present invention relates to a fastening structure of a damper (15) for reducing vibration of a washing tub in a drum washing machine. In particular, by using a damper pin, a damping structure for solving problems such as bolt loosening generated in a conventional bolt fastening structure It is about.

종래의 드럼 세탁기는 도 1에 도시된 바와 같이 외곽 케이스(11)와, 상기 케이스 내부에 설치된 세탁조(12)와, 상기 세탁조 내부에 설치된 드럼(13)과, 상기 드럼과 연결되어 드럼을 회전시키는 구동 모터(17)와, 상기 드럼의 회전에 의해 발생되는 진동을 줄이기 위한 댐퍼(15)와, 상기 댐퍼와 연결되어 세탁조를 지지하는 베이스(14)와, 상기 베이스와 상기 댐퍼를 연결하는 볼트(16)와, 세탁조의 위치를 복원하는 스프링(18)으로 구성되어 있다.The conventional drum washing machine is connected to the outer case 11, the washing tub 12 installed inside the case, the drum 13 installed inside the washing tub, and the drum as shown in FIG. 1 to rotate the drum. A drive motor 17, a damper 15 for reducing vibration generated by the rotation of the drum, a base 14 connected to the damper to support a washing tank, and a bolt connecting the base and the damper ( 16) and a spring 18 for restoring the position of the washing tank.

상기 볼트로 연결된 댐퍼 체결 구조는 도 2에 도시된 바와 같이 상기 댐프(15)와, 상기 베이스(14) 또는 세탁조(12)와, 볼트(16)와, 상기 볼트와 결합을 이루는 너트(21)와, 상기 볼트 머리 밑에 설치되어 볼트가 느슨해지는 것을 방지하는 와셔(22)로 구성되어 있다.As shown in FIG. 2, the damper fastening structure connected by the bolt has the damper 15, the base 14 or the washing tank 12, the bolt 16, and the nut 21 which is engaged with the bolt. And a washer 22 installed under the bolt head to prevent the bolt from loosening.

상기 드럼 세탁기에서 세탁 및 탈수할 때, 우선 구동 모터(17)가 회전하면 구동 모터와 연결된 상기 드럼(13)이 회전하여 세탁물(19)을 세탁하거나 탈수시킨다.When washing and dehydrating the drum washing machine, first, when the driving motor 17 rotates, the drum 13 connected to the driving motor rotates to wash or dehydrate the laundry 19.

상기 드럼(13)이 회전하면 상기 드럼에 진동이 발생되고, 상기 진동은 드럼 외곽의 세탁조(12)에 전달된다.When the drum 13 rotates, vibration is generated in the drum, and the vibration is transmitted to the washing tub 12 outside the drum.

상기 전달된 진동은 세탁조(12)와 외곽 케이스(11)에 연결된 스프링(18)에 전달된다. 또한, 상기 진동은 볼트(16), 너트(21), 와셔(22)로 이루어진 댐퍼 체결 부(20)를 통해 댐퍼(15)와 베이스(14)로 전달된다. 상기 전달된 진동은 댐퍼의 작용에 의해 감소된다.The transmitted vibration is transmitted to the spring 18 connected to the washing tub 12 and the outer case 11. In addition, the vibration is transmitted to the damper 15 and the base 14 through the damper coupling portion 20 consisting of the bolt 16, the nut 21, the washer 22. The transmitted vibration is reduced by the action of the damper.

그러나, 상기와 같이 구성된 종래의 세탁기의 댐퍼 체결 구조는 진동에 의해 볼트(16)가 풀리고, 상기 볼트 풀림에 의해 소음이 발생되며, 상기 볼트(16), 너트(21), 와셔(22)의 사용으로 체결 작업이 어렵고, 체결을 높이기 위해 와셔(22)가 사용되어 부품수가 증가되는 문제점이 있다.However, in the damper fastening structure of the conventional washing machine configured as described above, the bolt 16 is loosened by vibration, and noise is generated by the bolt loosening, and the bolt 16, the nut 21, the washer 22 The use of the fastening operation is difficult, there is a problem that the number of parts is increased by using the washer 22 to increase the fastening.

본 발명은 상기한 종래 기술의 문제점을 해결하기 위하여 안출된 것으로서, 댐퍼 체결시 댐퍼 핀을 사용하여 볼트 풀림 방지와, 소음의 감소와, 부품수의 절감이 가능한 세탁기의 댐퍼 체결 구조를 제공하는데 그 목적이 있다.The present invention has been made to solve the above problems of the prior art, and provides a damper fastening structure of a washing machine capable of preventing bolt loosening, noise reduction, and the number of parts by using a damper pin when the damper is fastened. There is a purpose.
