Description
본 고안은, 세탁기의 세탁조 진동 감쇄용 진동감쇄장치에 관한 것으로서, 보다 상세하게는, 세탁기의 탈수작동시 발생하는 세탁조의 진동을 감쇄시키기 위해 세탁기 외조의 하부에 설치한 진동감쇄장치에 관한 것이다.The present invention relates to a vibration damping device for reducing the washing tank vibration of the washing machine, and more particularly, to a vibration damping device provided in the lower portion of the outer tub of the washing machine to attenuate the vibration of the washing tank generated during the dehydration operation of the washing machine.
제3도는 종래의 세탁기의 측단면도이다. 이 도면에 도시된 바와 같이, 종래의 세탁기는 외관을 구성하는 본체(52)와, 현가장치(55)에 의해 본체(52) 내에 설치되어 있는 외조(51)와, 외조(51) 내에 설치되어 있는 세탁조(53)를 가지고 있다.3 is a side cross-sectional view of a conventional washing machine. As shown in this figure, the conventional washing machine is provided in the main body 52 constituting the exterior, the outer tank 51 installed in the main body 52 by the suspension device 55 and the outer tank 51. It has a washing tank 53.
외조(51)는 다수의 현가장치(55)에 의해 본체(52)내에 지지되어 있으며, 외조(51)의 하부에는 구동모터(61) 및 회전축조립체(63)가 설치되어 있다. 회전축조립체(63)의 하부에는 지지부(65)가 설치되어 회전축조립체(63)가 외조(51)에 견고히 부착되도록 지지한다.The outer tub 51 is supported in the main body 52 by a plurality of suspension devices 55, and a drive motor 61 and a rotating shaft assembly 63 are provided below the outer tub 51. A lower portion of the rotary shaft assembly 63 is installed to support the support 65 so that the rotary shaft assembly 63 is firmly attached to the outer shell (51).
구동모터(61)는 벨트(67)를 통해 회전축조립체(63)에 동력을 전달하며, 회전축조립체(63)는 회전축(69)을 통해 세탁조(53) 또는 세탁조(53) 내에 설치되어 있는 회전날개(57)를 회전구동시킨다. 세탁을 할 때에는 회전날개(57)가 회전하여 세탁조(53)내에 수용된 세탁물을 회전시키며, 탈수를 할 때에는 세탁조(53)를 회전시킨다.The drive motor 61 transmits power to the rotating shaft assembly 63 through the belt 67, and the rotating shaft assembly 63 is installed in the washing tank 53 or the washing tank 53 through the rotating shaft 69. Rotate (57). When washing, the rotary blade 57 rotates to rotate the laundry contained in the washing tank 53, and when washing, the washing tank 53 is rotated.
이상과 같은 구성에 의하여, 탈수행정시 세탁조(53)가 고속으로 회전함에 따라 세탁조(53)내의 세탁물이 탈수된다. 세탁조(53)가 회전할 때, 세탁조(53)내에 수용된 세탁물이 세탁조(53) 내에 고르게 분포하지 않고 한쪽으로 편중되어 분포할 경우에 진동이 발생하며, 이러한 진동은 특히 탈수작동의 초기에 세탁물의 편중이 심하여 많이 발생한다.With the above configuration, the laundry in the washing tank 53 is dewatered as the washing tank 53 rotates at a high speed during the dehydration administration. When the washing tub 53 rotates, vibration occurs when the laundry contained in the washing tub 53 is unevenly distributed in the washing tub 53 and is distributed to one side, and this vibration is particularly carried out at the beginning of the dehydration operation. A lot of bias occurs.
세탁조(53)가 진동하면, 세탁조(53)는 회전축조립체(63)에 의해 지지된 상태로 외조(51) 내에 수용되어 있으므로, 그 진동은 외조(51)에 전달되어 외조(51)가 심하게 흔들리는 현상이 발생한다.When the washing tub 53 vibrates, the washing tub 53 is accommodated in the outer tub 51 in a state supported by the rotating shaft assembly 63, so that the vibration is transmitted to the outer tub 51 so that the outer tub 51 vibrates violently. Phenomenon occurs.
그런데, 이러한 종래의 세탁기에 있어서는, 세탁물의 편중이 심하여 진동이 매우 심할 경우 현가장치만으로는 진동에 대한 감쇠력이 부족하여 외조가 본체의 내벽면에 부딪쳐 소음이 발생하거나 탈수작동 자세가 정지되는 문제점이 있다.By the way, in the conventional washing machine, when the laundry is very heavy and the vibration is very severe, the suspension device lacks the damping force against the vibration alone, so that the outer tank hits the inner wall of the main body, causing noise or dehydration operation to stop. .
따라서, 본 고안의 목적은, 탈수를 할 때, 세탁물의 편중에 의해 발생하는 세탁조의 진동을 감쇠시켜 세탁조 및 외조의 진동이 적으며, 특히 물 등의 이물질의 침투에 의한 영향이 없이 일정한 진동감쇄력을 유지할 수 있는 세탁조 진동 감쇄용 진동감쇄장치를 제공하는 것이다.Therefore, the object of the present invention, when dehydration, attenuates the vibration of the washing tank caused by the bias of the laundry, less vibration of the washing tank and the outer tank, in particular constant vibration damping force without the influence of the infiltration of foreign substances such as water It is to provide a vibration damping device for damping the vibration washing tub to maintain.

이하에서는 첨부도면을 참조하여 본 고안에 대해 상세히 설명한다.Hereinafter, with reference to the accompanying drawings will be described in detail for the subject innovation.
제1도는 본 고안에 따른 진동감쇄장치를 갖는 세탁기의 측단면도이고, 제2도는 제1도의 진동감쇄장치의 확대분해사시도이다. 본 고안에 따른 세탁기는 종래의 세탁기와 마찬가지로 거의 사각통형상의 본체(2)와, 본체(2)내에 수용되어 있는 외조(1)와, 외조(1) 내에 회전가능하게 수용되어 세탁물의 세탁 및 탈수작동을 하는 세탁조(3)를 가진다. 외조(1)는 본체(2)내에 현가장치(5)에 의해 설치되어 있다.1 is a side cross-sectional view of a washing machine having a vibration damping device according to the present invention, Figure 2 is an enlarged exploded perspective view of the vibration damping device of FIG. The washing machine according to the present invention, like a conventional washing machine, has a substantially rectangular cylindrical body 2, an outer tub 1 accommodated in the main assembly 2, and a rotatable accommodating inside the tub 1 for washing and washing laundry. It has the washing tank 3 which performs dehydration operation. The outer tub 1 is provided in the main body 2 by the suspension apparatus 5.
외조(1)의 하부에는 구동모터(11) 및 회전축조립체(13)가 설치되어 있고, 회전축조립체(13)의 하부에는 지지부(14)가 설치되어 있다.The drive motor 11 and the rotating shaft assembly 13 are provided in the lower part of the outer tub 1, and the support part 14 is provided in the lower part of the rotating shaft assembly 13. As shown in FIG.
구동모터(11)의 동력은 벨트(15)를 통해 회전축조립체(13)에 전달되며, 회전축조립체(13)는 회전축(18)을 통해 세탁조(3) 또는 세탁조(3)내에 설치되어 있는 회전날개(7)를 회전구동시킨다. 세탁을 할 때에는 회전날개(7)가 회전하여 세탁조(3)내에 수용된 세탁물을 회전시키며 탈수를 할 때에는 세탁조(3)를 회전시킨다.Power of the drive motor 11 is transmitted to the rotary shaft assembly 13 through the belt 15, the rotary shaft assembly 13 is installed in the washing tank 3 or the washing tank 3 through the rotating shaft 18. Rotate (7). When washing, the rotary blade 7 rotates to rotate the laundry contained in the washing tank 3, and when washing, the washing tank 3 is rotated.
한편, 외조(1)의 하부와 본체(2)의 저부면 사이에는 진동감쇄장치(30)가 설치되어 있다. 진동감쇄장치(30)는 중앙영역에 관통공(26, 28)이 형성된 진동감쇄장치상판(21) 및 진동감쇄장치하판(23)과, 진동감쇄장치상판(21)과 진동감쇄장치하판(23) 사이에 개재되며 중앙부위에 관통공(26, 28)보다 작은 직경을 갖는 진동감쇄장치축공(27)이 형성된 진동감쇄중간판(22)을 가진다.On the other hand, a vibration damping device 30 is provided between the lower portion of the outer tub 1 and the bottom surface of the main body 2. The vibration damping device 30 includes a vibration damping device upper plate 21 and a vibration damping device lower plate 23 having a through hole 26 and 28 formed in a central area, a vibration damping device upper plate 21 and a vibration damping device lower plate 23. ) And a vibration damping intermediate plate 22 having a vibration damping device shaft hole 27 having a diameter smaller than the through holes 26 and 28 in the central portion.
이들 진동감쇄장치상판(21), 진동감쇄장치중간판(22) 및 진동감쇄장치하판(23)은 경질의 플라스틱 재질로 형성되어 있으며, 진동감쇄장치중간판(22)은 진동감쇄장치상판(21) 및 진동감쇄장치하판(23)보다 다소 작게 형성되어 있다.The vibration damping device upper plate 21, the vibration damping device middle plate 22, and the vibration damping device lower plate 23 are formed of a hard plastic material, and the vibration damping device middle plate 22 is the vibration damping device upper plate 21. And the vibration damping device lower plate 23 is formed somewhat smaller.
진동감쇄장치상판(21)과 진동감쇄장치하판(23)은 외측 둘레구간에 다수의 체결공(29)이 형성되어 있어, 이들 체결공(29)에 나사(17)가 관통하여 너트(19)와 체결됨으로써, 진동감쇄장치상판(21)과 진동감쇄장치하판(23)이 결합되어 상호 고정되며, 나사(17)와 진동감쇄장치하판(23) 사이에는 스프링(32)이 개재되어 있다. 이에 따라 나사(17)가 다소 느슨하게 체결된 상태에서 스프링(32)이 진동감쇄장치하판(23)을 가압하여 진동감쇄장치상판(21)과의 결합력이 일정하게 유지된다. 따라서, 진동감쇄장치하판(23)과 진동감쇄장치중간판(22), 진동감쇄장치중간판(22)과 진동감쇄장치상판(21) 사이의 마찰력도 일정하게 유지된다.The vibration damping device upper plate 21 and the vibration damping device lower plate 23 have a plurality of fastening holes 29 formed in the outer circumferential section, and the screws 17 penetrate through the fastening holes 29 so that the nut 19 By coupling with, the vibration damping device upper plate 21 and the vibration damping device lower plate 23 is coupled to each other, the spring 32 is interposed between the screw 17 and the vibration damping device lower plate 23. Accordingly, in the state in which the screw 17 is loosely fastened, the spring 32 presses the vibration damping device lower plate 23 to maintain a constant coupling force with the vibration damping device upper plate 21. Therefore, the frictional force between the vibration damper lower plate 23 and the vibration damper middle plate 22, the vibration damper middle plate 22, and the vibration damper upper plate 21 is also kept constant.
또한, 진동감쇄장치하판(23)과 진동감쇄장치중간판(22)에는 다수의 마찰접촉부(31)가 각 판면으로부터 돌출형성되어 있다. 이들 마찰접촉부(31)에 의해 각 판들의 결합상태에서 진동감쇄장치하판(23)과 진동감쇄장치중간판(22) 및 진동감쇄장치중간판(22)과 진동감쇄장치상판(21)은 소정 이격되도록 배치되게 되어 이들 판사이에 유입되는 물 등의 이물질은 이격된 공간으로 다시 유출되게 되므로 각 판면간의 마찰력을 일정하게 유지할 수 있게 된다.Further, a plurality of frictional contact portions 31 are formed on the vibration damper lower plate 23 and the vibration damper intermediate plate 22 from each plate surface. The vibration damping device lower plate 23, the vibration damping device intermediate plate 22, and the vibration damping device middle plate 22 and the vibration damping device upper plate 21 are separated by a predetermined distance from each other by the friction contact portion 31. Since foreign matters, such as water flowing between these plates, are discharged back to the spaced space, the frictional force between the plates can be kept constant.
진동감쇄장치하판(23)의 측면에는 본체(2)의 바닥면을 향해 하향절곡된 연장부(35)가 형성되어 있고, 연장부(35)의 자유단부는 본체(2)의 바닥면(4)과 나란하게 절곡되어 있으며, 절곡된 단부에는 고정공(37)이 형성되어 있다. 고정공(37)에는 고정나사(39)가 체결되어 본체(2)의 바닥면(4)에 진동감쇄장치하판(23)이 고정되며, 이에 따라 진동감쇄장치(30)가 외조(2)의 하부에 설치된다.An extension part 35 bent downward toward the bottom surface of the main body 2 is formed at the side of the vibration damping device lower plate 23, and the free end of the extension part 35 is the bottom surface 4 of the main body 2. ) Is bent side by side, and a fixing hole 37 is formed at the bent end. The fixing screw 39 is fastened to the fixing hole 37 so that the vibration damping device lower plate 23 is fixed to the bottom surface 4 of the main body 2. As a result, the vibration damping device 30 of the outer tub 2 is fixed. It is installed at the bottom.
회전축조립체(13)를 지지하는 지지부(14)의 하부에는 진동감쇄장치축(16)이 설치되어 있다. 진동감쇄장치축(16)은 세탁조(3)의 회전축선을 따라 하향하여 형성되어 있으며, 진동감쇄장치상판(21)의 관통공(26)과 진동감쇄장치중간판(22)의 진동감쇠장치축공(27) 및 진동감쇠장치하판(23)의 관통공(28)을 관통한다. 진동감쇄장치축공(27)의 직경은 진동감쇄장치축(16)의 직경보다 다소 크게 형성되어 있으며, 진동감쇄장치축공(27)의 내측면에는 고무재질로 된 고리상의 소음감쇄부재(38)가 부착되어 있다.The vibration damping device shaft 16 is provided in the lower part of the support part 14 which supports the rotating shaft assembly 13. The vibration damping device shaft 16 is formed downward along the rotation axis of the washing tub 3, and the vibration damping device shaft hole of the through hole 26 of the vibration damping device upper plate 21 and the vibration damping device intermediate plate 22 is formed. And a through hole 28 of the lower plate 23 of the vibration damping device. The diameter of the vibration damper shaft hole 27 is formed to be somewhat larger than the diameter of the vibration damper shaft 16. A ring-shaped noise damping member 38 made of rubber material is formed on the inner surface of the vibration damper shaft hole 27. Attached.
이상과 같은 구성에 의하여, 탈수행정이 작동되면 세탁조(3)가 회전함에 따라 세탁조(5)내의 세탁물이 탈수된다. 이때, 세탁조(3)내 세탁물의 편중에 따라 세탁조(3)가 진동하게 되면 외조(2)가 진동하게 되고, 이 진동이 진동감쇄장치축(16)에 전달되어 진동감쇄장치축(16)이 수평방향으로 진동하게 된다.By the above configuration, when the dehydration stroke is operated, the laundry in the washing tank 5 is dewatered as the washing tank 3 rotates. At this time, when the washing tank 3 vibrates according to the load of the laundry in the washing tank 3, the outer tank 2 vibrates, and the vibration is transmitted to the vibration damping shaft 16 so that the vibration damping shaft 16 is It vibrates in the horizontal direction.
이에 따라 진동감쇄장치축(16)이 진동감쇄장치축공(27)에 걸리게 되므로 진동감쇄장치중간판(22)이 진동감쇄장치하판(23) 및 진동감쇄장치상판(21)과 일정한 마찰력을 가지고 움직이게 되므로, 이 마찰력에 의해 진동이 감쇄된다. 세탁조(3)는 정상적인 작동 중에도 다소의 진동은 있게 되는데, 진동감쇄장치축공(27)의 직경이 진동감쇄장치축(16)의 직경보다 다소 크게 형성되어 정상작동을 할 때 발생하는 진동에 의해 진동감쇄장치축(16)이 움직이는 영역 이상의 크기를 가지므로, 정상작동시에는 진동감쇄장치축(16)의 진동이 진동감쇄장치중간판(22)의 움직임을 유발하지 않게 된다.Accordingly, the vibration damper shaft 16 is caught by the vibration damper shaft hole 27 so that the vibration damper middle plate 22 moves with the vibration damper lower plate 23 and the vibration damper upper plate 21 with a constant frictional force. Therefore, vibration is attenuated by this frictional force. The washing tank 3 has some vibration even during normal operation, and the diameter of the vibration damper shaft hole 27 is slightly larger than the diameter of the vibration damper shaft 16 to vibrate due to vibration generated during normal operation. Since the damper shaft 16 has a size larger than a moving region, the vibration of the vibration damper shaft 16 does not cause movement of the vibration damper intermediate plate 22 in the normal operation.
따라서, 정상작동에 해당하는 진동 이상의 진동이 있을 경우에만 진동감쇄장치중간판(22)의 이동에 의한 마찰력에 의해 진동의 감쇄가 있게 되며, 진동감쇄장치축(16)의 이동에 의해 진동감쇄장치축(16)이 진동감쇄장치축공(27)의 측면에 부딪혀 소음이 발생하는 것을 막는다. 또한, 진동감쇄장치축공(27)의 내측면에 부착된 소음감쇄부재(38)에 의해 이상 진동시 진동감쇄장치축(16)과 진동감쇄장치축공(27)이 부딪칠 때 발생하는 소음이 줄어들게 된다.Therefore, vibration is attenuated by the frictional force caused by the movement of the vibration damper intermediate plate 22 only when there is vibration or more corresponding to the normal operation, and the vibration damping device is moved by the vibration damper shaft 16. The shaft 16 hits the side of the vibration damper shaft hole 27 to prevent the noise from occurring. In addition, the noise attenuation member 38 attached to the inner surface of the vibration damper shaft hole 27 reduces the noise generated when the vibration damper shaft 16 and the vibration damper shaft hole 27 collide when abnormal vibration occurs. do.
스프링(32)은 탄성력에 의해 일정한 크기의 힘으로 진동감쇄장치상판(21)과 진동감쇄장치하판(23)을 가압하므로, 장기간의 사용에 의해 진동감쇄장치상판(21), 진동감쇄장치중간판(22) 및 진동감쇄장치하판(23)이 마모되더라도 적절한 크기의 마찰력을 유지할 수 있다.Since the spring 32 presses the vibration damping device upper plate 21 and the vibration damping device lower plate 23 with a predetermined magnitude of force by elastic force, the vibration damping device upper plate 21 and the vibration damping device middle plate are used for a long time. Even if the 22 and the vibration damping device lower plate 23 wear, the friction force of an appropriate size can be maintained.
이상에서 설명한 바와 같이, 본 고안에 따르면, 외조 하부의 진동감쇄장치에 의해 탈수시 외조의 진동을 효과적으로 감쇄시켜 진동에 의한 소음을 억제시킬 수 있으며, 진동감쇄장치의 각 판면에 돌출형성된 마찰접촉부에 의해 각 판면이 소정이격되게 형성되어 이물질의 침투에 영향을 받지 않아 마찰력을 일정하게 유지할 수 있다.As described above, according to the present invention, the vibration damping device in the lower part of the outer tank effectively attenuates the vibration of the outer tank when dewatering to suppress noise due to vibration, and the friction contact portion protruding on each plate surface of the vibration damping device. As a result, each plate surface is formed to be spaced a predetermined distance so that the friction force is kept constant without being affected by the infiltration of foreign matter.
