본 고안은 1조식세탁기의 완충 수단으로 사용되는 걸이봉에 관한 것으로 특히 압축스프링의 유효 권선수 조절이 가능한 세탁기용 걸이봉에 관한 것이다.The present invention relates to a hanger rod used as a shock absorbing means of a one-piece washing machine, and more particularly, to a hanger rod for a washing machine capable of adjusting the effective number of turns of a compression spring.

상용화된 세탁기는 그 세탁방식에 따라 세탁조의 중앙에 회전가능하게 취부되어진 애지테이터라 불리우는 세탁봉이 규칙적으로 회전하면 세탁봉의 측면에 형성되어 있는 교반날개가 세탁조내에 저수된 세탁용수를 교반하여 수류를 형성하게 되고, 이 수류에 의하여 세탁물이 세탁용수 중에서 부유하면서 세탁봉 및 세탁조의 벽과 마찰되면서 세탁이 이루어지도록 하는 방식의 교반식세탁기, 세탁조의 하단부에 회전가능하게 취부된 펼세이터가 회전하여 소용돌이 형태의 수류를 발생시켜 세탁물을 돌리는 방식으로서 가장 널리 사용되고 있는 방식 중의 하나인 와류식세탁기 및 다수개의 통수구가 형성되어 있는 원통형의 드럼을 저수조내에 수평으로 회전가능하게 취부시키고, 이를 회전시키므로써 드럼내의 돌기에 의하여 세탁물을 드럼내의 상방의 공간으로 끌어 올렸다가 중력에 의하여 하방으로 낙하시키면서 세탁토록 구성되어져 있으며, 대용량의 세탁에 적절한 것으로 가정용보다는 세탁업소에서 많이 사용되는 드럼식세탁기로 대별될 수 있다.According to the washing method, the washing machine called agitator, which is rotatably mounted in the center of the washing tank, is regularly rotated according to the washing method, and the stirring blade formed on the side of the washing bag stirs the washing water stored in the washing tank to form a stream of water. In this way, the laundry is suspended in the washing water while the laundry floats in the wash water and rubs with the walls of the washing rod and the washing tank, and the vortex type is rotated at the bottom of the washing tank by rotating the washing machine. One of the most widely used method of generating the water flow to rotate the laundry, the vortex type washing machine and the cylindrical drum formed with a plurality of water holes are rotatably mounted in the water tank and rotated horizontally. The upper part of the drum in the drum by turning It is designed to be washed while being pulled down by space and falling downward by gravity, and it is suitable for large-capacity washing and can be roughly classified as a drum type washing machine used in a laundry shop rather than a home.

상기의 세탁기들 중 가정용으로 널리 사용되는 것은 와류식으로 이는 조의 형상에 따라 1개의 조내부에 세탁조와 펄세이터를 취부시켜 용도에 따라 펄세이터만을 또는 펄세이터와 세탁조를 회전시켜 세탁을 수행하는 1조식세탁기와 각각의 조에 펄세이터와 탈수통을 각각 취부시켜 구성된 2조식세탁기로 분류할 수 있으며, 이를 1조식세탁기를 일예로 설명하면 다음과 같다.Among the above washing machines are widely used for home use, which is a vortex type, in which a washing tank and a pulsator are mounted in one tank according to the shape of the tank to perform washing by rotating only the pulsator or the pulsator and the washing tank according to the purpose. The washing machine and each tank can be classified into a two-chamber washing machine configured by attaching a pulsator and a dehydrating container, respectively.

제1도에 도시한 바와 같이, 종래의 1조식세탁기는 주로 펄세이터(3)의 회전에 의하여 수류를 형성시키는 와류식세탁기로서, 세탁용수를 수용하는 저수조(1)내에 세탁조(2)를 회전가능하게 고정시키고, 상기 세탁조(2)의 내측 하단에 수류의 형성을 위한 펄세이터(3)를 역시 회전가능하게 취부시키고, 이들 세탁조(2)와 펄세이터(3)를 저수조(1)의 저면세 취부되어진 전동모터(4) 및 그에 연동되는 감속기어조립체(5)에 연결시켜 감속기어조립체(5)를 통한 감속된 출력을 사용하여 구동시켜 세탁, 헹굼 및 탈수를 선택적으로 또는 순차적으로 가능하게 하여 세탁물의 전 세탁과정을 하나의 조 내에서 일괄적으로 처리할 수 있도록 하고 있다.As shown in FIG. 1, the conventional single-chamber washing machine is a vortex-type washing machine which mainly forms water flow by the rotation of the pulsator 3, and rotates the washing tank 2 in the storage tank 1 containing the washing water. Securely fixed, and also the pulsator (3) for the formation of water flow on the inner bottom of the washing tank (2) is also rotatably mounted, and these washing tank (2) and pulsator (3) It is connected to the electric motor 4 and the reduction gear assembly 5 interlocked with the exemption, and is driven using the decelerated output through the reduction gear assembly 5 so that washing, rinsing and dehydration can be selectively or sequentially performed. Therefore, the entire laundry process of laundry can be processed in one group.

상기와 같이 구성된 세탁기는 전동모터(4)에 의해 연동되는 펄세이터(3)나 세탁조(2)의 회전시 많은 진동이 발생하고 있다. 특히 세탁이 완료된 세탁물로부터 수분을 제거하기 위해 탈수시 세탁조(2)에 세탁물이 불균일하게 넣어지게되면 그 진동은 더욱 심하게 된다. 상기와 같은 진동을 억제하기 위한 수단으로 세탁조(2)의 상단에 비중이 큰 염수등이 내장된 밸런서(7)부를 형성시켰으며, 세탁조(2)나 펄세이터(3) 또는 전동모터(4)의 회전에 의해 발생된 진동이 세탁기의 외상을 통하여 외부로 발산되는 것을 방지하기 위한 수단으로는 걸이봉(6)을 사용하고 있다.The washing machine configured as described above generates a lot of vibration when the pulsator 3 or the washing tub 2 rotated by the electric motor 4. In particular, if the laundry is unevenly put into the washing tank 2 during dehydration to remove moisture from the laundry, the vibration is more severe. As a means for suppressing the vibration as described above formed a balancer (7) having a built-in brine, such as a specific gravity at the upper end of the washing tank (2), washing tank (2), pulsator (3) or electric motor (4) The hook rod 6 is used as a means for preventing the vibration generated by the rotation of the radiator from releasing to the outside through the trauma of the washing machine.

상기 걸이봉(6)은 걸이봉(6)을 외상의 상단과 저수조(1)의 하단 사이에 연결시키는 로드(60), 로드(60)의 하부에 삽입되어 저수조(1)의 진동을 완충시키는 압축스프링(61), 상기 압축스프링(61)과 피스톤(63)이 내장되고 상단부가 저수조(1) 하단에 형성된 걸이봉걸림턱에 걸리도록 구성된 원통형의 하우징(62) 및 상기 로드(60)의 하단에 취부되어 압축스프링(61)의 하단을 지지하므로써 저수조(1)의 유동에 따라 하우징(62)의 상단에 압력이 가해졌을 때 압축스프링(61)의 하단에 압축을 가하므로써 저수조(1)의 유동을 압축스프링(61)에 전달하는 피스톤(63)등으로 구성되어 전동모터(4)나 세탁조(2) 등의 진동에 의한 저수조(1)가 아래로 눌리면 로드(60)의 하단에 결합된 피스톤(63)이 하우징(62)의 내부에서 상부로 밀려올라가고 피스톤(63)의 상부에 면접된 압축스프링(61)이 압축되어 저수조(1)의 유동이 세탁기의 외상까지 전달되지 않고 걸이봉(6)의 압축스프링(61)에 의해 흡수되어 완충된다.The hook rod 6 is inserted into the rod 60, the lower portion of the rod 60 to connect the hook rod 6 between the upper end of the trauma and the lower end of the reservoir 1 to cushion the vibration of the reservoir (1) Compression spring 61, the compression spring 61 and the piston 63 of the cylindrical housing 62 and the rod 60 is configured to be hooked to the hook rod engaging jaw formed at the bottom of the reservoir (1) Mounted at the lower end to support the lower end of the compression spring 61 by applying pressure to the lower end of the compression spring 61 when pressure is applied to the upper end of the housing 62 in accordance with the flow of the reservoir (1) Composed of a piston (63) for transmitting the flow of the compression spring (61), etc. is coupled to the lower end of the rod (60) when the reservoir (1) is pressed down by the vibration of the electric motor (4) or the washing tank (2) Compressed piston (63) is pushed upward from the inside of the housing (62) and interviewed on the upper portion of the piston (63) The compressed water is absorbed and buffered by the compression spring 61 of the hook rod 6 without passing the flow of the water storage tank 1 to the trauma of the washing machine.

그러나 상기와 같이 구성된 걸이봉(6)은 저수조의 용량이 클 세탁기와 작은 세탁기에 모두 사용되므로 저수조(1)의 용량이 큰 세탁기에 사용시에는 압축스프링(61)의 유효 권선수가 지나치게 많아 압축스프링(61)의 탄성이 저수조(1)의 무게를 견디지 못하여 진동이 걸이봉(6)을 따라 세탁기의 외상과 상부판으로 전달되어 소음이 발생하게 되는 문제가 있었다.However, since the hook rod 6 configured as described above is used in both a washing machine and a small washing machine having a large storage tank capacity, when the washing rod 6 is used in a washing machine having a large storage tank 1, the effective number of windings of the compression spring 61 is excessively high. The elasticity of 61) could not withstand the weight of the reservoir 1, and there was a problem that the vibration was transmitted to the outer plate and the upper plate of the washing machine along the hook rod 6 to generate noise.

따라서 본 고안은 이와 같은 종래의 결점을 해소시키기 위하여 안출된 것으로 저수조의 용량에 관계없이 사용할 수 있도록 압축스프링의 유효권선수를 조절할 수 있는 걸이봉을 제공함을 목적으로 한다.Therefore, the present invention has been made to solve such a conventional drawback, and an object of the present invention is to provide a hanger rod that can adjust the effective winding of the compression spring to be used regardless of the capacity of the reservoir.

이와 같은 목적을 갖는 본 고안은 걸이봉의 하우징 내주면에 압축스프링의 유효 권선수를 조절할 수 있는 걸림턱을 형성시키는 것이다.The present invention having such a purpose is to form a locking step that can adjust the effective number of windings of the compression spring on the inner peripheral surface of the hook rod.
