In more detail, the vibration absorbing device of the present invention relates to a vibration absorbing device of the support rod. The present invention relates to a vibration absorbing device of a washing machine capable of realizing the quietness of a device.
일반적으로 세탁기의 주요구성요소로서는, 도면 제1도에서와 같이 수조(2)와 탈수조(1)로 이루어지는 세탁조(10)와, 상기 세탁조(10)의 구동을 위한 구동부(4)와, 세탁조(10)와 구동부(4) 그리고 그 밖의 전장물을 포위하고 있는 외체(3)와 상기 세탁조(10)와 외체(3) 사이에 설치되어 세탁조(10)에 대해 현수가능하고 세탁조(10)로 부터 발생되어지는 진동에너지를 흡수 감쇄시켜주는 다수개의 진동흡수수단(6)과 뚜껑(5)으로 이루어지며, 이 진동흡수수단(6)의 구성요소는 도면 제4도에서와 같이 세탁조(10)의 수조(2)하측에 세탁조의 진동이 전달되게 고정설치되며, 세탁조의 진동이 직접적으로 전달되므로 인해 연동되면서 실린더 기능을 갖는 유동캡(62)과, 상기 유동캡(62)의 내측면에 대해 긴밀한 접촉상태를 유지토록 설치되며, 다음에 설명되는 지지봉(61) 하단에 고정된 피스톤 기능의 지지판(63)과, 상기 유동캡(62)의 안내통로(62a)를 관통하여 지지판(63)에 일단이 접속구성되고, 그 타단은 외체(3)의 고정부재(65)에 이탈방지토록 고정핀으로 고정된 강체환봉으로 이루어진 지지봉(61)과, 상기 유동캡(62)과 지지판(63) 사이에 지지봉(61)에 삽입된 상태로 설치되어 유동캡(62)에 대해 탄력을 부여하는 탄성부재(64)로 이루어진 구성을 갖으며, 이는 세탁기의 사용에 의해 세탁조(10)로 부터 진동에너지가 발생되면, 그 진동에너지가 유동캡(62)에 직접적으로 전달되어 지지봉(61)에 매달린 지지판(63)에 대하여 유동캡(62)이 상, 하왕복운동을 하므로써, 지지판(63)과 유동캡(62)에서 마찰력이 발생하였고, 또 유동캡(62)의 상, 하왕복운동시, 유동캡(62)과 지지판(63) 각각은 실린더와 피스톤역할을 하게되어 공기가 유동캡(62)의 안내통로(62a)와 지지봉(61)사이공간을 통해 흡기 또는 배기동작을 하게 되었던 것이다. 따라서 상기와 같은 진동흡수장치의 마찰력과 공기의 흡, 배기력에 의해 세탁조의 진동에너지가 흡수감쇄처리되었다.In general, as the main components of the washing machine, as shown in FIG. 1, a washing tank 10 including a water tank 2 and a dehydration tank 1, a driving unit 4 for driving the washing tank 10, and a washing tank (10) and the outer portion (3) surrounding the drive unit (4) and other electrical equipment, and installed between the washing tank (10) and the outer body (3) is susceptible to the washing tank (10) and to the washing tank (10) It consists of a plurality of vibration absorbing means (6) and the lid (5) for absorbing and attenuating the vibration energy generated from, the components of the vibration absorbing means (6) as shown in FIG. The water tank (2) of the lower side of the washing tank is fixedly installed to be transmitted, because the vibration of the washing tank is directly transmitted due to the flow cap 62 having a cylinder function and with respect to the inner surface of the flow cap 62 It is installed to maintain a close contact state, and is described below the support rod 61 One end is connected to the support plate 63 through the support plate 63 having the fixed piston function and the guide passage 62a of the flow cap 62, and the other end thereof is the fixing member 65 of the outer body 3. The support rod 61 made of a rigid rod bar fixed to the fixing pin to prevent the separation and the flow cap 62 and the support plate 63 is installed in a state inserted into the support rod 61 for the flow cap 62 It has a configuration consisting of an elastic member 64 to give elasticity, which is generated when the vibration energy from the washing tank 10 by the use of a washing machine, the vibration energy is directly transmitted to the flow cap 62 is supported rod ( As the flow cap 62 moves up and down relative to the support plate 63 suspended from 61, friction forces are generated at the support plate 63 and the flow cap 62, and the top and bottom of the flow cap 62. In the reciprocating motion, each of the flow cap 62 and the support plate 63 serves as a cylinder and a piston so that air guides the flow cap 62. Through the space between (62a) and the support bar 61 will have been to the intake or exhaust action. Therefore, the vibration energy of the washing tank was absorbed and attenuated by the frictional force of the vibration absorbing device as described above and the suction and exhaust force of the air.
이러한 종래의 진동흡수장치에 있어서는, 유동캡(62)의 안내통로(62a)내주연과, 지지봉(61) 외주연과의 사이간격(S)을 크게 제조하였다.In such a conventional vibration absorbing device, the space S between the inner circumferential edge of the guide passage 62a of the flow cap 62 and the outer circumferential edge of the support rod 61 is largely manufactured.
왜냐하면, 유동캡(62)의 변형(유동캡은 사출성형품인 관계로 사출조건이나 계절의 변화에 따른 치수변화 등)에 대한 대비를 위하여 사이간격(S)을 크게할 수 밖에 없었던 것이고, 또, 세탁조(10)의 진동에 따른 유동캡(62)의 상, 하왕복 운동시(이때, 지지판은 지지봉에 매달린 상태로 위치고정되어있음)유동캡(62)은 실린더로서, 지지판(63)은 피스톤으로서 역할을 하게될때, 안내통로(62a)와 지지봉(61)사이간격(S)을 통해 공기가 원할하게 흡, 배기토록 하기위하여 사이간격(S)을 크게 제조하였던 것이다.Because, in order to prepare for deformation of the flow cap 62 (flow cap is an injection-molded product, such as dimensional change according to the injection conditions or seasonal changes, etc.) was to increase the interval (S), and, When the upper and lower reciprocating motions of the flow cap 62 according to the vibration of the washing tank 10 (in this case, the support plate is fixed in a state suspended from the support rod), the flow cap 62 is a cylinder, the support plate 63 is a piston When acting as, the gap (S) was made large so that the air is smoothly sucked, exhausted through the gap (S) between the guide passage (62a) and the support rod (61).
따라서 종래의 진동흡수장치에서는 유동캡(62)의 안내통로(62a)와 지지봉(61) 외주연 사이간격이 크게 구성되어있어 유동캡(62)의 상, 하 왕복운동중에 유동캡 안내통로(62a)의 내주연과 지지봉(61) 외주연 사이에서 불규칙적인 마찰이 발생되었으며 그 결과 청감이 아주 나쁜 마찰소음이 유발될 수 밖에 없는 실정이었다.Therefore, in the conventional vibration absorbing device, the gap between the guide passage 62a of the flow cap 62 and the outer circumferential edge of the support rod 61 is large, so that the flow cap guide passage 62a during the up and down reciprocating motion of the flow cap 62 is provided. Irregular friction occurred between the inner circumference of the inner periphery and the outer circumference of the support rod (61), and as a result, the hearing was inevitably caused by friction noise.
즉, 기기의 정음설계제작이 불가능하였던 것이다.In other words, it was impossible to manufacture the silent design of the device.
이러한 문제점을 해소하기 위한 방안으로써, 공지의 유동이 원활하게 이루어지도록한 조건을 충족시키지 못한 상태에서 유동캡(62)의 안내통로(62a)와 지지봉(61) 외주연 사이간격을 작게하였을 경우에는, 유동캡(62)의 변형에 따른 기기의 불량요인이 발생되었으며, 또 공기의 유동이 원할하게 이루어지지 못하여 이상진동이 발생되었던 것이다.As a solution to this problem, when the gap between the guide passage 62a of the flow cap 62 and the outer circumferential edge of the support rod 61 is small in a state in which the known flow is not satisfied, , Defect factors of the device according to the deformation of the flow cap 62 was generated, and the abnormal vibration was generated because the flow of air was not made smoothly.
본 고안은 이와같은 종래의 제반 문제점을 해결하기 위하여 안출된 것으로써, 본 고안은 세탁기의 외체내부에서, 세탁조를 현수상태로 지지하여주고, 세탁조의 진동에너지를 흡수, 감쇄시켜주는 세탁기 진동흡수장치에서 세탁조의 진동에너지가 전달됨에 따른 유동캡의 상, 하 왕복운동시, 유동캡의 안내통로를 통해 공기의 유동이 원할하게 이루어지도록한 조건을 충족하면서, 유동캡의 안내통로와 지지봉간에 거의 면접촉상태를 유지토록하여 유동캡 안내통로와 지지봉사이에서 부드러운 느낌을 주는 마찰음이 발생될 수 있도록 함으로써, 세탁기의 정음화를 실현할 수 있는 세탁기의 진동흡수장치를 제공하는데 그 목적이 있다.The present invention has been devised to solve such a conventional problem, the present invention is to support the washing tank in the suspension state in the outer body of the washing machine, washing machine vibration absorption device for absorbing and attenuating the vibration energy of the washing tank In the upper and lower reciprocating motion of the flow cap as the vibration energy of the washing tank is transferred, the surface almost meets between the guide passage and the support rod of the flow cap while satisfying the condition that the air flows smoothly through the guide passage of the flow cap. It is an object of the present invention to provide a vibration absorbing device of a washing machine capable of realizing quietness of the washing machine by maintaining a contact state so that a friction sound giving a soft feeling can be generated between the flow cap guide passage and the supporting rod.
이러한 목적을 달성하기 위한 본 고안의 특징적인 구성요소로서는 세탁기의 세탁조 진동에너지를 흡수 감쇄시킬 수 있는 진동흡수장치에서, 유동캡이 왕복운동을 할때, 유동캡의 안내통로와 지지봉 사이가 면접촉상태를 유지토록 안내통로를 작게구성하고, 또 안내통로를 작게구성함에 따른 제품의 변형문제, 공기유동문제를 보상토록 유통캡의 안내통로 상측부위에 개방부를 가짐을 특징으로 한다.As a characteristic component of the present invention for achieving this purpose, in the vibration absorbing device capable of absorbing and attenuating the vibration energy of the washing tank of the washing machine, when the flow cap reciprocates, the surface contact between the guide passage of the flow cap and the support rod It is characterized in that the guide passage is configured to keep the state small, and the opening portion is formed on the upper side of the guide passage of the distribution cap to compensate for the deformation problem and air flow problem of the product by configuring the guide passage small.

이 진동흡수수단(6)에 대하여는, 도면 제2도 및 제3도에서와 같이 유동캡(62)의 내측에는 지지판(63)이 내장되어져 상기 유동캡(62)의 안내통로(62a)를 관통한 지지봉(61)하단에 고정되어 있으며, 유도캡(62) 내측상면과 지지판(63) 상면사이에는 탄성부재(64)가 지지봉(61)에 삽입된 상태로 탄지되어 유동캡(62)에 대해 탄력을 부여하는 구성이다.With respect to the vibration absorbing means 6, as shown in Figs. 2 and 3, a support plate 63 is built in the inside of the flow cap 62 to penetrate the guide passage 62a of the flow cap 62. It is fixed to the lower end of one support rod 61, between the inner upper surface of the guide cap 62 and the upper surface of the support plate 63, the elastic member 64 is inserted into the support rod 61, and is supported by the flow cap 62. It is a configuration that gives elasticity.
상기 유동캡(62)의 내벽면과 지지판(63) 외주면 사이에는 긴밀한 접촉상태를 유지토록 구성되어진다.It is configured to maintain a close contact between the inner wall surface of the flow cap 62 and the outer peripheral surface of the support plate 63.
또 공기유도로 역할을 하는 유동캡(62)의 안내통로(62a)는 외부로 돌출되는 부위와 내측으로 돌출되는 부위로 길게 구성되어진다.In addition, the guide passage (62a) of the flow cap 62, which serves as an air induction is composed of a long protruding portion and a portion projecting inward.
또한, 지지봉(61)의 상단은 세탁기 위체(3)의 고정부재(65)에 구비된 안내통로(65a)를 통해 관통결합되어 고정핀(66)에 의하여 고정부재(65)에 이탈방지케 고정되어있다.In addition, the upper end of the support rod 61 is penetrated through the guide passage (65a) provided in the fixing member 65 of the upper body of the washing machine (3) is fixed to the fixing member 65 by the fixing pin (66). It is.
이러한 통상적인 세탁기에 있어서 본 고안의 진동흡수장치는 유동캡(62)의 안내통로(62a)상부로 돌출된 부위에 공기유동을 도모토록하고, 제품의 수축변형을 보상할 수 있는 개방부(T)가 형성되어 있고, 또, 유동캡(62)의 안내통로(62a)의 내경을 작게하여, 안내통로(62a)와 지지봉(61) 사이에서 면접촉을 유지할 수 있도록한 구성이다.In such a conventional washing machine, the vibration absorbing device of the present invention locks the air flow to a portion protruding above the guide passage 62a of the flow cap 62, and an opening portion T for compensating shrinkage deformation of the product. Is formed, and the inner diameter of the guide passage 62a of the flow cap 62 is made small so that the surface contact can be maintained between the guide passage 62a and the support rod 61.
또한, 고정부재(65)의 안내통로(65a) 돌출된 부위에 제품의 수축변형을 보상토록한 개방부(T1)를 형성하여 구성하게된다.In addition, the opening portion (T1) for compensating the shrinkage deformation of the product is formed on the protruding portion of the guide passage (65a) of the fixing member (65).
이와같이 구성하여서된 본 고안은 세탁조(10)를 이루는 탈수조(1)내에 소정의 세탁물을 장입한 상태에서 세탁조 구동부(4)의 구동력에 의하여 탈수조(1)가 회전중심축을 기준으로 회전되는 과정에서 세탁물의 불균형등에 의해 수조(2)에 진동에너지가 발생될 경우에는, 고정판(2a)에 직접적으로 진동이 전달작용되므로 외체(3)에 대해 세탁조(10)를 현수하고 있는 진동흡수수단(6)의 유동캡(62)과 고정부재(65)는 심하게 진동을 하게되며, 이로인하여는 유동캡(62)이 상, 하운동을 취하게 되면서, 탄성부재(64)를 연속 반복적으로 압축, 팽창시키게된다.The present invention constituted as described above is a process in which the dehydration tank 1 is rotated based on the central axis of rotation by the driving force of the washing tank driving unit 4 in a state in which predetermined laundry is loaded into the dehydration tank 1 constituting the washing tank 10.

Through the guide passage (62a) of the air while the intake, exhaust action, absorbs and dissipates the transmitted vibration to perform a normal dehydration function.
이와같은 진동흡수수단(6)에 의한 진동흡수, 감쇄작동과정에서, 유동캡(62)의 상, 하 왕복운동시 유동캡(62)의 안내통로(62a)내측벽과 지지봉(61)의 외주연사이에서 마찰이 발생되는데, 이때, 본 고안은 공기유동이 원할하게 이루어지도록한 조건하에서 유동캡(62)의 안내통로(62a) 내경을 줄여 지지봉(61)과의 사이간격을 최소로한 구조이기 때문에, 유동캡(62)의 상, 하왕복운동시, 유동캡안내통로(62a)와 지지봉(61)간에 거의 면접촉된 상태를 유지한 채 왕복운동이 이루어져 부드러운 느낌을 주는 마찰음이 발생되는 것이다.In the vibration absorption and attenuation operation by the vibration absorbing means 6, the inner wall of the guide passage 62a of the flow cap 62 and the outside of the supporting rod 61 during the up and down movement of the flow cap 62. Friction is generated between the peripheral edges, in which the present invention has a structure in which the gap between the support rod 61 is minimized by reducing the inner diameter of the guide passage 62a of the flow cap 62 under the condition that the air flow is smoothly made. Because of this, during the upper and lower reciprocating motion of the flow cap 62, the reciprocating movement is made while the surface of the flow cap guide passage (62a) and the support bar 61 is almost kept in contact with the friction sound that gives a soft feeling is generated will be.
또한 유동캡(62)의 안내통로(62a)돌출부위에 개방부(T)가 형성되어 있어, 유동캡(62)의 수축변형을 개방부(T)에 의해 어느정도 보상할 수 있으며, 또 개방부(T) 형성에 의한 안내통로(62a)의 길이를 단축시키는 석과 같은 효과를 얻을수 있게되어 유동캡(62)의 상, 하왕복운동시, 안내통로(62a)를 통해서 이루어지는 공기의 흡기, 배기동작이 원활하게 이루어지게 되는것이다.In addition, the opening part T is formed in the protrusion part 62a of the flow cap 62, and the shrinkage deformation of the flow cap 62 can be compensated to some extent by the opening part T, and the opening part ( T) It is possible to obtain the same effect as the stone to shorten the length of the guide passage (62a) by the formation, so that the air intake and exhaust operation through the guide passage (62a) during the up and down movement of the flow cap 62 It will be done smoothly.
한편, 고정부재(65)의 지지봉안내통로(65a) 돌출부위에 개방부(T1)를 두고, 안내통로(65a)와 지지봉(61)간에 사이간격을 최소로하여 마찰음 발생을 방지토록한 것이다.On the other hand, the opening portion (T1) is provided on the protruding portion of the support bar guide passage (65a) of the fixing member 65, to minimize the interval between the guide passage (65a) and the support bar 61 to prevent the occurrence of friction sound.
이상에서 상술한 바와같이 지지봉(61)이 관통되는 유동캡(62)과 고정부재(65)의 안내통로(62a)(65a) 각각에 개방부(T)(T1)를 형성하면서 그 내경을 줄여 안내통로의 내경과 지지봉과의 사이간격을 최소로 하여서된 본 고안의 진동흡수장치는, 진동흡수장치의 작동중에 지지봉과 각각의 안내통로 사이에서 발생되어지는 불규칙적인 마찰소음을 부드러운 마찰음으로 변환시켜줌으로써 기기의 정음화를 실현할 수 있고, 사출물인 유동캡과 고정부재의 변형방지와 공기유동을 도모할 수 있는 효과를 얻을수 있는 것이다.As described above, the inner diameter of the flow cap 62 and the guide passages 62a and 65a of the fixing member 65 through which the support rod 61 is formed is formed, thereby reducing the inner diameter thereof. The vibration absorbing device of the present invention minimizes the distance between the inner diameter of the guide passage and the support rod, and converts the irregular friction noise generated between the support rod and each guide passage into a soft friction sound during the operation of the vibration absorber. It is possible to realize the quietness of the equipment and to achieve the effect of preventing deformation and air flow of the flow cap and the fixing member which are the injection molding products.
