Description
본 고안은, 진동감쇠용 진동감쇠부재를 갖는 세탁기에 관한 것으로서, 보다 상세하게는, 탈수행정시 세탁조내 세탁물의 편중에 의해 발생되는 외조 상부영역의 진동을 효과적으로 감쇠시킬 수 있어 탈수행정을 원활하게 할 수 있도록 한 세탁기에 관한 것이다.The present invention relates to a washing machine having a vibration damping member for vibration damping, and more particularly, to smoothly damp the vibration of the upper portion of the outer tank generated by the bias of the laundry in the washing tank during the dehydration stroke, thereby smoothly dehydrating the stroke. It's about one washing machine.
도4는 종래의 세탁기의 측단면도이다. 이 도면에 도시된 바와 같이, 종래의 세탁기는 외관을 구성하는 본체(62)와, 본체(62)내에 설치되어 있는 외조(61)와, 외조(61)내에 설치되어 있는 세탁조(63)를 가지고 있다.4 is a side cross-sectional view of a conventional washing machine. As shown in this figure, a conventional washing machine has a main body 62 constituting an outer appearance, an outer tub 61 provided in the main body 62, and a washing tub 63 installed in the outer tub 61. have.
외조(61)는 하부영역에 설치된 다수의 현가장치(65)에 의해 본체(62)내에 지지 되어 있으며, 외조(61)의 하부에는 구동모터(67) 및 회전축조립체(68)가 설치되어 있다. 구동모터(67)는 벨트(71)를 통해 회전축조립체(68)에 동력을 전달하며, 회전축조립체(68)는 회전축(73)을 통해 세탁을 할 때에는 세탁조(63)를 회전시키고, 탈수를 할 때에는 세탁조(63)내에 설치되어 있는 회전날개(66)를 회전시킨다.The outer tank 61 is supported in the main body 62 by a plurality of suspension devices 65 provided in the lower region, and a drive motor 67 and a rotating shaft assembly 68 are provided below the outer tank 61. The drive motor 67 transmits power to the rotating shaft assembly 68 through the belt 71, and the rotating shaft assembly 68 rotates the washing tub 63 when washing through the rotating shaft 73, and dewatering. At that time, the rotary blade 66 provided in the washing tub 63 is rotated.
이상과 같이 구성에 의하여, 탈수행정을 할 때, 세탁조(63)가 고속으로 회전함에 따라 진동이 발생한다. 이러한 진동은 세탁물이 세탁조(63)내에 고르게 분포하지 않고 한쪽으로 편중되어 분포할 경우에 발생하며, 특히 탈수행정의 초기에 세탁물의 편중이 심하여 많이 발생한다.By the above configuration, when the dehydration stroke is performed, vibration occurs as the washing tank 63 rotates at a high speed. This vibration occurs when the laundry is not evenly distributed in the washing tank 63 and is biased to one side, and the laundry is heavily biased at the beginning of the dehydration stroke.
이렇게, 세탁조(63)가 진동하는 경우, 세탁조(63)는 회전축조립체(68)에 의해 지지된 상태로 외조(61)내에 수용되어 있으므로, 그 진동은 외조(61)에 전달되어 외조(61)가 심하게 흔들리는 현상이 발생한다. 외조(61)를 본체(62)의 내부에 매달아 지지하고 있는 현가장치(65)는 진동을 감쇠시키는 완충장치의 역할을 겸하고 있다.Thus, when the washing tub 63 vibrates, since the washing tub 63 is accommodated in the outer tub 61 in a state supported by the rotating shaft assembly 68, the vibration is transmitted to the outer tub 61 and the outer tub 61. Severe shaking occurs. The suspension device 65 supporting the outer tub 61 by hanging inside the main body 62 serves as a shock absorber for damping vibration.
그런데, 이러한 종래의 세탁기에 있어서는, 세탁물의 편중이 심하여 진동이 심화되면 현가장치(65)만으로는 진동의 감쇠력이 부족하여 심한 경우 외조(61)가 본체(62)의 내벽면에 부딪혀 소음이 발생하거나 탈수행정 자체가 정지되기도 한다.By the way, in such a conventional washing machine, if the vibration is intensified due to the heavy load of the laundry, the suspension device 65 lacks the damping force of the vibration alone, and in a severe case, the outer tank 61 hits the inner wall surface of the main body 62 to generate noise. The dehydration administration itself may be suspended.
특히, 이러한 진동은 외조(61)의 상부에서 더 심하게 발생한다.In particular, this vibration occurs more severely at the top of the outer tub 61.
따라서, 본 고안의 목적은, 탈수행정시 세탁조내 세탁물의 편중에 의해 발생하는 외조 상부의 진동을 감쇠시켜, 세탁조 및 외조의 진동이 적고 탈수행정이 원활하게 수행되는 세탁기를 제공하는 것이다.Accordingly, an object of the present invention is to attenuate the vibration of the upper portion of the outer tank generated by the bias of the laundry in the washing tank during the dehydration operation, to provide a washing machine with less vibration of the washing tank and the outer tank and smoothly performs the dewatering stroke.

또한, 상기 진동감쇠부재는 경질의 고무재질로 이루어진 것이 효과적이다.In addition, the vibration damping member is made of a hard rubber material is effective.
이하에서는 첨부도면을 참조하여 본 고안에 대해 상세히 설명한다.Hereinafter, with reference to the accompanying drawings will be described in detail for the subject innovation.
도1은 본 고안에 따른 진동감쇠부재를 갖는 세탁기의 측단면도이고, 도2는 도1의 지진동감쇠부재를 도시한 것으로서, a)도는 평면도이고, b)도는 측단면도이며, 도3은 도1의 부분확대평면도이다. 이들 도면에 도시된 바와 같이, 본 고안에 따른 세탁기는 종래의 세탁기와 마찬가지로, 외관을 형성하는 거의 사각통형상의 본체(1)와, 현가장치(6)에 의해 본체(1)내에 수용되는 외조(3)와, 외조(3)내에 설치되며, 세탁물이 수용되는 탈수조(5)를 가진다.Figure 1 is a side cross-sectional view of a washing machine having a vibration damping member according to the present invention, Figure 2 is a seismic dynamic damping member of Figure 1, a) is a plan view, b) is a side cross-sectional view, Figure 3 is Figure 1 Partial enlarged plan view of. As shown in these figures, the washing machine according to the present invention, like the conventional washing machine, has a substantially rectangular cylindrical main body 1 forming an external appearance and an outer tub housed in the main body 1 by the suspension device 6. (3) and a dehydration tank (5) provided in the outer tub (3), in which laundry is accommodated.
한편, 외조(3)의 상측 개구연부에는 외조덮개(7)가 결합되어 있으며, 외조덮개(7)에는 외조(3)와 본체(1)의 내벽면을 연결하는 복수의 진동감쇠부재(30)가 설치되어 있다.On the other hand, the outer lid cover 7 is coupled to the upper opening edge of the outer tank 3, the plurality of vibration damping members 30 connecting the outer tank 3 and the inner wall surface of the main body 1 to the outer shell cover 7. Is installed.
이들 진동감쇠부재(30)는 일측 단부에 형성된 고정공(31)을 통해 볼트(21)가 외조덮개(7)에 체결되며, 타측 단부는 고정공(31')에 또 다른 볼트(21')가 체결되어 본체(1)의 상부 모서리부에 현가장치(6)를 지지할 수 있도록 형성되어 있는 현가장치지지부(8)에 고정된다. 이에 의해 네 개의 진동감쇠부재(30)가 외조(3) 상부의 둘레구간을 따라 방사상으로 균분 배치되어 본체(1) 및 외조(3)에 고정된다.These vibration damping members 30 are fastened to the outer cover (7) by the bolt 21 through the fixing hole 31 formed at one end, the other end is another bolt 21 'to the fixing hole 31' Is fastened to the suspension support 8 which is formed to support the suspension 6 at the upper edge of the main body 1. As a result, four vibration damping members 30 are radially equally disposed along the circumferential section of the upper portion of the outer tub 3 and fixed to the main body 1 and the outer tub 3.
진동감쇠부재(30)는 양단부에 고정공(31,31')이 형성되어 있는 막대형상으로 형성되어 있다. 진동감쇠부재(30)는 경질의 고무로 제조되며 길이방향으로는 거의 변형되지 않고 길이방향의 가로방향으로는 가요성을 가진다.The vibration damping member 30 is formed in a rod shape having fixing holes 31 and 31 'formed at both ends thereof. The vibration damping member 30 is made of hard rubber and hardly deformed in the longitudinal direction and has flexibility in the transverse direction in the longitudinal direction.
이상과 같은 구성에 의하여, 탈수행정시 탈수조(5)가 고속회전하게 되면, 탈수조(5)에 수용되어 있는 세탁물들이 한쪽으로 치우친 경우 발생되는 세탁조(5)의 진동이 외조(3)에 전달된다. 이렇게 외조(3)에 전달된 진동은 외조(3)의 상부영역과 본체(1)의 내벽면 사이를 연결하며, 길이방향으로 변형되지 않고 길이방향의 가로방향으로 탄성적으로 휘어지는 진동감쇠부재(30)에 의해 진동이 감쇠된다.By the above configuration, when the dehydration tank 5 rotates at high speed during the dehydration administration, the vibration of the washing tank 5 generated when the laundry contained in the dehydration tank 5 is biased to one side is applied to the outer tank 3. Delivered. The vibration transmitted to the outer tub 3 connects between the upper region of the outer tub 3 and the inner wall surface of the main body 1, and is a vibration damping member that is elastically bent in the transverse direction in the longitudinal direction without being deformed in the longitudinal direction. Vibration is attenuated by 30).
이에 따라, 진동에 의한 소음이 감소할 뿐만 아니라 탈수행정을 원활하게 할 수 있다.Accordingly, not only noise due to vibration is reduced, but also dehydration stroke can be smoothly performed.
이상에서 설명한 바와 같이, 본 고안에 따르면, 탈수행정시 세탁조내 세탁물의 편중에 의해 발생하는 외조 상부의 진동을 감쇠시켜, 세탁조 및 외조의 진동이 적고 탈수행정이 원활하게 수행되는 세탁기가 제공된다.As described above, according to the present invention, there is provided a washing machine that attenuates the vibration of the upper part of the outer tank generated by the bias of the laundry in the washing tank during the dehydration operation, thereby reducing the vibration of the washing tank and the outer tank and performing the dehydrating stroke smoothly.
