Description
본 고안은 드럼 세탁기용 댐퍼에 관한 것으로, 특히 세탁통(Tub)의 진동을 효과적으로 흡수하면서 소음을 저감하고 제조단가를 낮춘 드럼 세탁기용 댐퍼에 관한 것이다. The present invention relates to a damper for a drum washing machine, and more particularly, to a damper for a drum washing machine which reduces noise and lowers manufacturing costs while effectively absorbing vibration of a washing tub (Tub).
주지된 바와 같이 드럼 세탁기에는 회전하는 세탁통을 3점 또는 2점 방식으로 지지하여 이 세탁통의 진동을 흡수하는 댐퍼가 설치되어 있는바, 즉 드럼 세탁기용 댐퍼는 회전하는 세탁통의 진동을 효율적으로 흡수할 수 있을 뿐만 아니라, 댐퍼 자체에서 이 세탁통을 지지하는 보유 지지력을 제공함으로써 서스펜션과 같은 추가 지지품을 필요하지 않게 되어 있다.As is well known, a drum washing machine is provided with a damper for supporting a rotating washing machine in a three- or two-point manner to absorb vibrations of the washing machine. That is, the drum washing machine damper can efficiently absorb the vibration of the rotating washing machine. Not only can it be provided, but the damper itself provides a holding force for supporting the laundry, thus eliminating the need for additional support such as suspension.
종래 이와 같은 역할을 수행하는 댐퍼는 스프링으로 탄지된 로드의 전후 이동을 오일과 스프링으로 감쇠하여 세탁통을 지지하도록 되어 있으나, 오일과 같은 댐핑요소를 사용함으로 인한 제조단가 상승과 작동시 실린더 로드와 오일의 마찰음으로 인해 작동음인 소음이 크게 발생하여 제품의 정숙성을 떨어뜨리는 문제점이 제기되어 왔다.Conventionally, a damper that performs such a role is designed to support a laundry container by damping forward and backward movement of a rod supported by a spring with oil and a spring, but a cylinder rod and oil during operation and an increase in manufacturing cost by using a damping element such as oil. Due to the frictional noise of the noise generated as a large operating noise has been a problem that reduces the quietness of the product.
이에 본 고안은 상기와 같은 문제점을 해결하기 위해 안출된 것으로, 댐퍼의 작동오일을 사용하지 않으면서 작동시 진동과 소음을 저감시키며, 구조의 단순화로 제조단가를 낮추는 드럼 세탁기용 댐퍼를 제공함에 그 목적이 있다. The present invention has been made to solve the above problems, to reduce the vibration and noise during operation without using the operation oil of the damper, and to provide a damper for drum washing machine to lower the manufacturing cost by simplifying the structure There is a purpose.
상기와 같은 목적을 달성하기 위한 본 고안은 한쪽 선단에 축이 설치되는 실린더와 이 실린더의 타단에 설치된 로드가 제 1, 2 호울더를 매개로 스프링으로 탄지되어 이루어진 드럼 세탁기용 댐퍼에 있어서, 상기 실린더에 연결되는 로드의 일측단은 실린더 내부에 장착된 양쪽 메탈을 관통하여 리테이너를 매개로 빈 공간의 실린더 내부에 설치되되, 상기 안쪽 메탈은 둘레 압착 노치부로, 다른쪽 메탈은 실린더 끝단에 형성된 플랜지로 각각 실린더 내부에서 고정 장착되고, 상기 양쪽 메탈 사이에는 댐퍼 케이스로 감싸진 댐퍼와 윤활유가 내장되며, 상기 제 1, 2 호울더 사이에 탄지된 스프링은 중앙이 양쪽 선단보다 지름이 크게 설정된 스프링으로 이루어져 있다.The present invention for achieving the above object is a drum washing machine damper in which a cylinder is installed on one end of the shaft and the rod installed on the other end of the cylinder is supported by a spring through the first and second holders, One end of the rod connected to the cylinder passes through both metals mounted inside the cylinder, and is installed inside the cylinder in the empty space via a retainer. The inner metal is a circumferential crimp notch, and the other metal is a flange formed at the end of the cylinder. Each of which is fixedly mounted in the cylinder, and between the metals, a damper and a lubricant surrounded by a damper case are built-in, and a spring supported between the first and second holders is a spring whose center is larger in diameter than both ends. consist of.
이하, 본 고안을 첨부된 예시도면을 참조로 상세히 설명한다. Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
도 1과 도 2는 본 고안에 따른 드럼 세탁기용 댐퍼의 전체 구조를 나타낸 정면도와 이의 길이방향 단면도이다.1 and 2 are a front view and a longitudinal cross-sectional view showing the entire structure of a damper for a drum washing machine according to the present invention.
본 고안은 도면에 도시된 바와 같이 드럼 세탁기의 세탁통에 보유 지지되어 이 세탁통 회전시 진동과 소음을 저감시키는 역할을 수행하는 댐퍼로서, 한쪽 선단에 축(1)이 설치되는 실린더(2)와, 이 실린더(2)의 타단에 설치된 로드(3)가 제 1, 2 호울더(4a,4b)를 매개로 스프링(5)으로 탄지되어 이루어진 드럼 세탁기용 댐퍼에 있어서, 상기 실린더(2)에 연결되는 로드(3)의 일측 헤드단(3a)는 실린더(2) 내부에 장착된 양쪽 메탈(6a,6b)을 관통하여 리테이너(7)를 매개로 빈 공간의 실린더(2) 내부에 설치되되, 상기 안쪽 메탈(6a)은 둘레 압착 노치부(12)로, 다른쪽 메탈(6b)은 플랜지(8)로 각각 실린더(2) 내부에서 고정 장착되고, 이 양쪽 메탈(6a,6b) 사이에는 댐퍼 케이스(9)로 감싸진 댐퍼(10)와 윤활유(11)가 도포되어 이루어진 구조로 되어 있다.The present invention is a damper that is held in the laundry tub of the drum washing machine as shown in the drawing serves to reduce vibration and noise during the rotation of the laundry tub, the cylinder (2) is provided with a shaft (1) at one end, In the damper for a drum washing machine, in which a rod (3) installed at the other end of the cylinder (2) is supported by a spring (5) via first and second holders (4a, 4b), it is connected to the cylinder (2). One head end 3a of the rod 3 to be penetrated through both metals 6a and 6b mounted in the cylinder 2 is installed inside the cylinder 2 in the empty space via the retainer 7. The inner metal 6a is a circumferential crimp notch 12 and the other metal 6b is fixedly mounted inside the cylinder 2 by a flange 8, respectively, and a damper is provided between the two metals 6a and 6b. The damper 10 and the lubricating oil 11 wrapped in the case 9 are applied.
여기서, 상기 로드(3)의 길이방향 이동을 흡수하는 스프링(5)은 이 로드(3)에 고정된 제 1 호울더(4a)와 실린더(2)의 일측 둘레단에 고정된 제 2 호울더(4b) 사이에 탄지되어 있는데, 상기 제 1, 2 호울더(4a,4b) 사이에 탄지된 스프링(5)은 중앙부분이 양쪽 선단보다 지름이 더 큰 볼록한 형태로 되어 있어서 로드(3) 이동시 충격완화를 향상시킨다.Here, the spring 5 absorbing the longitudinal movement of the rod 3 has a first holder 4a fixed to the rod 3 and a second holder fixed to one circumferential end of the cylinder 2. (4b) between the first and the second holder (4a, 4b), the spring (5) is the convex shape of the central portion is larger than both ends and the rod (3) when moving Improves shock mitigation
한편, 상기 빈 공간을 갖는 실린더(2)는 철제와 같은 금속제로 되어 있으며, 이의 일측 구간에 축(1)을 압입하여 실린더(2)의 연결부분을 롤링으로 연결시킴에 따라 탈거되지 않도록 되어 있다.On the other hand, the cylinder (2) having the empty space is made of metal such as iron, and the shaft 1 is pressed in one section thereof, so that the connecting portion of the cylinder (2) is connected by rolling to prevent removal. .
그리고 상기 축(1)도 철제와 같은 금속제로 되어 있으면서 이 축(1)과 실린더(2)의 비틀림력, 빠짐력, 인장력이 일정수준 이상(약 120㎏f.㎝)을 유지시키어 세탁기 세탁통의 과도한 회전력이 지속적으로 작용되어도 상기 실린더(2)의 유격발생 및 탈거 우려가 없도록 되어 있다.The shaft 1 is also made of metal such as steel, and the torsional force, the pulling force, and the tensile force of the shaft 1 and the cylinder 2 are maintained at a predetermined level or more (about 120 kgf.cm). Even if excessive rotational force is continuously applied, there is no fear of the occurrence of play and removal of the cylinder 2.
또한, 상기 실린더(2) 내부에 조립되는 댐핑 요소로서는 양쪽 메탈(6a,6b)과 댐퍼 케이스(9) 및 그리스와 같은 윤활유(11)가 도포된 댐퍼(10)가 로드(3)에 끼워져 삽입 장착되어 있는데, 여기에서도 상기 댐핑요소들이 롤링작업으로 둘레 압착 노치부(12)와 플랜지(8)를 매개로 견고하게 조립된다.In addition, as the damping element assembled inside the cylinder 2, dampers 10 coated with both metals 6a and 6b and damper cases 9 and lubricating oil 11 such as grease are inserted into the rod 3 and inserted. The damping elements are also firmly assembled here via the circumferential crimp notch 12 and the flange 8 by rolling.
한편, 댐퍼력을 유지하기 위해 상기 안쪽 메탈(6a,6b)은 오일리스 베어링(Oilless bearing)으로 적용시키며, 소음저감을 위하여 댐퍼 케이스(7)와 댐퍼(10) 사이에는 그리스와 같은 윤활유(11)를 도포한다.On the other hand, the inner metal (6a, 6b) is applied to the oilless bearing (Oilless bearing) in order to maintain the damper force, lubricating oil such as grease 11 between the damper case 7 and the damper 10 for noise reduction ) Is applied.
따라서 본 고안에 따른 드럼 세탁기용 댐퍼는 세탁통에서 회전력으로 인한 충격을 받게 되면 로드(3)가 길이 방향으로 움직이게 되는데, 이때 스프링(5)에 의해 일차 댐핑이 이루어지고 상기 댐퍼(10)와 로드(3)의 마찰력 및 실린더(2)의 빈공간 공기 압축력에 의해 재차 댐핑이 이루어져서 진동과 소음을 저감시키도록 되어 있다.Therefore, when the damper for a drum washing machine according to the present invention is subjected to a shock due to the rotational force in the washing tub, the rod 3 moves in the longitudinal direction, in which the primary damping is made by the spring 5 and the damper 10 and the rod ( Damping is again performed by the frictional force of 3) and the air space compressing force of the cylinder 2 to reduce vibration and noise.
상기와 같이 본 고안에 따른 드럼 세탁기용 댐퍼 세탁통 회전시 진동감쇠와 소음을 저감시키면서 부품수의 단축으로 제조단가를 낮출 수 있는 효과를 지닌다. As described above, the damper washing drum for drum washing machine according to the present invention has an effect of reducing the manufacturing cost by reducing the number of parts while reducing vibration attenuation and noise.
