본 고안은 세탁조의 진동감쇠용 댐핑장치를 갖는 세탁기에 관한 것이다.The present invention relates to a washing machine having a damping device for damping vibration of a washing tank.

세탁기에서는, 세탁조 내에 세탁물을 수용하여 세탁, 탈수 등을 행할 수 있도록 되어 있다. 이러한 세탁기가 세탁 및 탈수공정을 수행하는 경우에는 세탁조의 회전이나 세탁조 내부에 설치된 펄세이터의 회전 등에 의하여 진동이 발생하게 된다. 이 진동을 감쇠시키기 위해 종래의 세탁기에는 진동감쇠장치가 마련되어 있다.In the washing machine, laundry, dehydration, and the like are accommodated in a washing tank. When the washing machine performs the washing and dehydration process, vibration may occur due to the rotation of the washing tank or the rotation of a pulsator installed in the washing tank. In order to damp this vibration, a conventional washing machine is provided with a vibration damping device.

제4도는 종래의 세탁기의 측단면도이다. 이 도면에서 도시된 바와 같이, 종래의 세탁기는 세탁기 전체의 외관을 구성하는 외부케이싱(101)과, 외부케이싱(101) 내에 설치되어 있는 외조(102)와, 외조(102) 내에 설치되어 있는 세탁조(103)를 가지고 있다.4 is a side cross-sectional view of a conventional washing machine. As shown in this figure, a conventional washing machine includes an outer casing 101 constituting the entire appearance of the washing machine, an outer tub 102 provided in the outer casing 101, and a washing tub installed in the outer tub 102. Has (103).

외조(102)는 다수의 서스펜션(109)에 의해 외부케이싱(101) 내에 매달려 지지되어 있고, 외조(102)의 하부에는 구동모터(104) 및 샤프트조립체(105)가 설치되어 있다. 샤프트조립체(105)의 주위를 둘러싸는 새들(106)은 샤프트조립체(105)가 외조(102)에 견고히 부착되도록 지지한다. 구동모터(104)의 동력은 벨트(107)를 통해 샤프트조립체(105)에 전달되고, 샤프트조립체(105)는 샤프트를 통해 세탁조(103) 또는 세탁조(103) 내의 펄세이터(108)를 회전구동시킨다.The outer tub 102 is suspended and supported in the outer casing 101 by a plurality of suspensions 109, and a drive motor 104 and a shaft assembly 105 are provided below the outer tub 102. The saddle 106 surrounding the shaft assembly 105 supports the shaft assembly 105 to be firmly attached to the outer shell 102. Power of the drive motor 104 is transmitted to the shaft assembly 105 through the belt 107, the shaft assembly 105 drives the washing tank 103 or the pulsator 108 in the washing tank 103 through the shaft. Let's do it.

이러한 구조로 이루어진 세탁기에서는, 탈수행정시에 세탁조(103)가 고속으로 회전함에 따라 진동이 발생한다. 이러한 진동은 세탁물이 세탁조(103) 내에 고르게 분포하지 않고 한쪽으로 편중되어 분포할 경우에 발생하며, 특히 탈수행정의 초기 동작시에 세탁물의 편중이 심하여 많이 발생한다. 세탁조(103)의 진동이 있는 경우, 세탁조(103)는 샤프트조립체(105)에 의해 지지된 상태로 외조(102)가 심하게 흔들리는 현상이 발생한다. 이러한 진동을 감쇠시키기 위해 외조(102)를 외부케이싱(101)의 내부에 매달아 지지하고 있는 서스펜션(109)은 진동을 감쇠시키는 장치의 역할을 겸하고 있다.In the washing machine having such a structure, vibration occurs as the washing tank 103 rotates at a high speed during the dehydration stroke. This vibration occurs when the laundry is not evenly distributed in the washing tank 103, but is biased to one side, and the laundry is heavily biased at the initial operation of the dehydration stroke. When the washing tub 103 is vibrated, the washing tub 103 is severely shaken by the outer tub 102 while being supported by the shaft assembly 105. Suspension 109, which holds and supports the outer tub 102 inside the outer casing 101 to damp these vibrations, also serves as a device for damping vibrations.

그러나, 세탁물의 편중이 심하여 진동이 매우 심할 경우에는 서스펜션(109) 만에 의해서는 진동이 감쇠되지 않아, 외조(102)가 외부케이싱(101)의 내벽면에 부딪히는 경우가 발생하기도 하며, 심한 경우 탈수행정 자체가 정지되기도 한다.However, when the laundry is severely biased and the vibration is very severe, the vibration is not attenuated by the suspension 109 alone, so that the outer tub 102 may hit the inner wall of the outer casing 101. The dehydration administration itself may be suspended.

따라서, 본 고안의 목적은, 세탁 및 탈수 중에 발생하는 진동을 적절하게 감쇠할 수 있는 댐핑장치를 구비한 세탁기를 제공하는 것이다.It is therefore an object of the present invention to provide a washing machine with a damping device capable of appropriately damping vibrations generated during washing and dehydration.

상기 목적은, 본 고안에 따라, 외부케이싱 내에 수용되는 외조와, 외조 내에 회전가능하게 설치되어 세탁물을 수용하는 세탁조를 갖는 세탁기에 있어서, 외조의 하부에 하향연장되어 외조의 진동에 따라 진동하는 댐핑축과, 댐핑축을 상하유동이 가능하게 통과시키는 댐핑공을 가진 댐핑중간판과, 댐핑중간판의 상면 및 하면에 각각 마찰접촉하는 판상의 댐핑상판 및 댐핑하판과, 댐핑상판과 댐핑하판 중 적어도 어느 하나와 댐핑중간판 사이에는 마찰부재가 개재되는 것을 특징으로 하는 세탁기에 의해 달성된다.According to the present invention, a washing machine having an outer tub accommodated in the outer casing, and a washing tub rotatably installed in the outer tub for accommodating laundry, the lower end of the outer tub is extended damping vibrating according to the vibration of the outer tub At least one of a damping intermediate plate having a shaft, a damping hole for allowing the up and down flow of the damping shaft to pass, a damping upper plate and a damping lower plate in friction contact with the upper and lower surfaces of the damping intermediate plate, and a damping upper plate and a damping lower plate, respectively. It is achieved by a washing machine, characterized in that the friction member is interposed between one and the damping intermediate plate.

여기서, 마찰부재로서는 스폰지나 우레탄이 채용될 수 있다. 댐핑상판과 댐핑하판의 상호 결합은 볼트체결로 간단하게 이루어질 수 있다.Here, a sponge or urethane may be employed as the friction member. The mutual coupling of the damping top plate and the damping bottom plate can be made simply by bolting.

이하에서 첨부도면을 참조하여 본 고안을 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

제1도는 본 고안에 따른 세탁기의 측단면도이다. 이 도면에서 도시된 바와 같이, 본 고안에 따른 세탁기는, 종래의 세탁기와 마찬가지로, 외관을 형성하는 외부케이싱(1)과, 외부케이싱(1) 내에 설치되어 있는 외조(2)와, 외조(2) 내에 회전가능하게 설치되어 있는 세탁조(3)를 가지고 있다. 외조(2)는 다수의 서스펜션(9)에 의해 외부케이싱(1) 내부에 탄성적으로 매달려 있고, 외조(2)의 하부에는 구동모터(4) 및 샤프트조립체(5)가 설치되어 있으며, 샤프트조립체(5)는 새들(6)에 의해 둘러싸여 있다. 구동모터(4)의 동력은 벨트(7)를 통해 샤프트조립체(5)에 전달되고, 샤프트조립체(5)는 샤프트를 통해 세탁조(3) 또는 세탁조(3) 내에 설치되어 있는 펄세이터(8)를 회전구동시킨다. 세탁행정시에는, 펄세이터(8)가 회전하여 세탁조(3) 내에 수용된 세탁물을 회전시키고, 탈수행정시에는 세탁조(3)를 회전시킨다. 세탁조(3)는 그 기능에 따라 탈수조라고도 불린다. 세탁조(3) 하부영역에는, 외조(2)의 진동을 감쇠할 수 있는 댐핑장치(20)가 새들(6)과 외부케이싱(1)의 베이스(10) 사이에 설치되어 있다.1 is a side cross-sectional view of a washing machine according to the present invention. As shown in this figure, the washing machine according to the present invention, like the conventional washing machine, the outer casing 1 to form an appearance, the outer tub 2 provided in the outer casing 1, and the outer tub 2 ) Has a washing tub (3) rotatably installed. The outer tub 2 is elastically suspended inside the outer casing 1 by a plurality of suspensions 9, and a drive motor 4 and a shaft assembly 5 are installed below the outer tub 2, and the shaft The assembly 5 is surrounded by the saddle 6. The power of the drive motor 4 is transmitted to the shaft assembly 5 via the belt 7, which shaft assembly 5 is installed in the washing tank 3 or in the washing tank 3 via the shaft. Rotate the In the washing stroke, the pulsator 8 rotates to rotate the laundry contained in the washing tub 3, and in the dehydration stroke, the washing tub 3 is rotated. The washing tank 3 is also called a dehydration tank according to the function. In the lower region of the washing tank 3, a damping device 20 capable of damping the vibration of the outer tank 2 is provided between the saddle 6 and the base 10 of the outer casing 1.

제2도는 댐핑장치(20)를 확대한 평면도이고, 제3도는 측단면도이다. 이들 도면에서 도시된 바와 같이, 새들(6) 하부의 중앙부위에는, 외조(2)의 진동에 따라 진동하는 댐핑축(21)이 하향고정 설치되어 있고, 이 댐핑축(21)이 통과하여 상하유동 가능하도록 댐핑축(21)보다 직경이 큰 댐핑공(23)을 가지는 원판상의 댐핑중간판(24)이 설치되어 있다. 이 댐핑중간판(24)의 상면에는 원판상의 댐핑상판(26)이 설치되어 있고, 그 하면에는 외부케이싱(1)의 하부영역에 고정된 지지판(28)에 설치되어 댐핑상판(26)과 함께 댐핑중간판(24)과 마찰접촉하는 댐핑하판(27)이 설치되어 있다. 댐핑상판(26)과 댐핑하판(27)은 그 연부에서 볼트(30)에 의해 상호 일체로 체결되어 있다. 그리고, 댐핑상판(26) 및 댐핑하판(27)과 댐핑중간판(24) 사이에는 각각 마찰부재(29)가 각각 개재되어 댐핑중간판(24)이 비교적 큰 마찰저항을 가지고 댐핑상판(26)과 댐핑하판(27) 사이에서 요동할 수 있도록 되어 있다. 이 마찰부재(29)는 스톤지나 우레탄 등의 비교적 내마모성이 큰 재질로 만들어 진다.2 is an enlarged plan view of the damping device 20, and FIG. 3 is a side cross-sectional view. As shown in these figures, the damping shaft 21 which vibrates in accordance with the vibration of the outer tub 2 is provided in the central portion of the lower part of the saddle 6, and the damping shaft 21 passes and moves up and down. A disk-shaped damping intermediate plate 24 having a damping hole 23 having a diameter larger than that of the damping shaft 21 is provided. The upper surface of the damping intermediate plate 24 is provided with a disk-shaped damping upper plate 26, and the lower surface thereof is provided on a support plate 28 fixed to the lower region of the outer casing 1 together with the damping upper plate 26. A damping lower plate 27 in frictional contact with the damping intermediate plate 24 is provided. The damping upper plate 26 and the damping lower plate 27 are integrally fastened to each other by bolts 30 at their edges. In addition, between the damping upper plate 26, the damping lower plate 27, and the damping intermediate plate 24, a friction member 29 is interposed therebetween so that the damping intermediate plate 24 has a relatively large frictional resistance and thus the damping upper plate 26. And swing between the damping lower plate 27. The friction member 29 is made of a material having a relatively high wear resistance such as stone paper or urethane.

이러한 구조에 의하여, 세탁기 운전 중, 특히 탈수시에, 세탁조(3)의 진동에 따라 외조(2)가 일체로 진동하게 되면, 댐핑축(21)도 함께 진동하게 된다. 외조(2)의 상하진동은 서스펜션(9)에 의해 완충 및 감쇠되고, 외조(2)의 좌우진동은, 댐핑축(21)이 외조(2)와 함께 좌우로 요동함에 따라, 댐핑중간판(24)도 따라서 좌우진동하여 댐핑상판(26)과 댐핑하판(27) 사이에서 마찰부재(29)에 마찰접촉하게 됨으로써 마찰저항을 받아 감쇠되게 된다.With this structure, when the outer tub 2 vibrates integrally with the vibration of the washing tub 3 during washing machine operation, in particular during dehydration, the damping shaft 21 also vibrates together. The up and down vibration of the outer tub 2 is buffered and attenuated by the suspension 9, and the left and right oscillations of the outer tub 2 are damped as the damping shaft 21 oscillates from side to side with the outer tub 2. 24 also vibrates from side to side and frictionally contacts the friction member 29 between the damping upper plate 26 and the damping lower plate 27 to be attenuated by frictional resistance.

이에 따라, 외조(2)를 탄성적으로 현수하고 있는 서스펜션(9)의 상하방향 진동감쇠효과에 부가하여, 댐핑상판(26)과 댐핑하판(27) 사이에서 마찰요동하는 댐핑중간판(24)의 좌우방향 마찰력에 의해 좌우방향에서의 진동이 감쇠된다.Accordingly, the damping intermediate plate 24 frictionally oscillates between the damping upper plate 26 and the damping lower plate 27 in addition to the vertical vibration damping effect of the suspension 9 which elastically suspends the outer tub 2. The vibration in the left and right directions is attenuated by the left and right frictional force of.

이상 설명한 바와 같이, 본 고안에 따르면, 세탁 및 탈수 중에 발생하는 진동을 적절하게 감쇠할 수 있는 댐핑장치를 구비한 세탁기가 제공된다.As described above, according to the present invention, a washing machine having a damping device capable of appropriately damping vibrations generated during washing and dehydration is provided.
