Accordingly, only the pulsator 32 rotates forward and backward during washing and rinsing stroke, and the washing tank 31 rotates at high speed together with the pulsator 32 during dehydration stroke.

한편, 현가장치(50)는 하우징(10) 각 코너와 수조(30) 사이에 마련되어 수조(30)를 하우징(10)내에 현가시키는데, 하우징(10) 내부 상측에 마련된 지지부(33)에 안착 결합되는 고정부(52)와, 수조(30)의 하측에 마련된 현가부(35)에 결합되는 완충부(55)와, 고정부(52)와 완충부(55) 사이에 배치되는 현가봉(53)을 구비한다.On the other hand, the suspension device 50 is provided between each corner of the housing 10 and the water tank 30 to suspend the water tank 30 in the housing 10, the seating coupling to the support portion 33 provided in the upper side of the housing 10 The fixed portion 52 and the buffer portion 55 coupled to the suspension portion 35 provided on the lower side of the water tank 30, and the suspension rod 53 disposed between the fixed portion 52 and the buffer portion 55. ).

현가부(35)는 수조(30)의 하부 측면에 외측으로 돌출되게 일체로 마련되어 완충부(55)가 삽입 고정될 수 있는 공간을 형성하며, 상면에 완충부(55)보다 작은 지름을 갖는 현가봉(53)이 여유있게 삽입될 수 있도록 홀(미도시)이 천공된다.Suspension portion 35 is integrally formed to protrude outward to the lower side of the water tank 30 to form a space in which the buffer portion 55 can be inserted and fixed, the upper surface has a diameter smaller than the buffer portion 55 A hole (not shown) is drilled to allow the gabon 53 to be inserted with ease.

완충부(55)는 방진스프링(56)과 방진고무(57)가 삽입되는 실린더 형상의 플라스틱 사출관으로, 상측에 현가봉(53)이 삽입되는 홀(55a)이 형성되고, 이의 하측은 개구되어 방진고무(57)가 배치되며 여기에 현가봉(53)의 선단이 결합된다. 이러한 방진고무(57)은 완충부(55) 내면에 밀착되어 마찰운동하면서 세탁기의 작동시 발생되는 진동을 흡수하게 된다. 또한, 방진스프링(56) 역시 진동을 흡수하도록 완충부(55) 내부공간에 설치되는데, 이것은 방진고무(57)와 완충부(55)가 서로 반대 방향으로 이동되며 마찰될때 방진고무(57)와 완충부(55)를 복원시키는 방향으로 지지하면서 진동을 흡수하게 된다.The shock absorbing portion 55 is a cylindrical plastic injection tube into which the anti-vibration spring 56 and the anti-vibration rubber 57 are inserted, and a hole 55a into which the suspension rod 53 is inserted is formed at an upper side thereof, and the lower side thereof is an opening. The anti-vibration rubber 57 is disposed and the tip of the suspension rod 53 is coupled thereto. The anti-vibration rubber 57 is in close contact with the inner surface of the buffer unit 55 to absorb the vibration generated during operation of the washing machine while friction movement. In addition, the anti-vibration spring 56 is also installed in the inner space of the shock absorbing portion 55 to absorb vibrations, which is when the anti-vibration rubber 57 and the shock absorbing portion 55 are moved in opposite directions and rubbed with the anti-vibration rubber 57 The vibration is absorbed while supporting the shock absorbing portion 55 in the restoring direction.

그리고, 현가봉(53)은 하측 선단이 방진고무와 결합되며 상측 선단이 고정부(52)의 중앙에 천공된 홀(52a)을 관통하여 고정부(52) 내측까지 연장된 금속재 와이어 봉으로 마련된다. 현가봉(53)의 상측 선단은 일측으로 벤딩되며, 벤딩부(54)에는 지지부(33)에 결합되는 고정부(52)가 마련된다.The suspension rod 53 is provided with a metal wire rod having a lower end coupled with the anti-vibration rubber and having an upper end penetrating the hole 52a drilled in the center of the fixing portion 52 and extending to the inside of the fixing portion 52. do. The upper end of the suspension rod 53 is bent to one side, the bending portion 54 is provided with a fixing portion 52 that is coupled to the support 33.

이 고정부(52)는 중앙에 현가봉(53)의 벤딩부(54)가 삽입될 수 있도록 홀(52a)이 천공된 반구형상으로 마련되어 있어서, 현가봉(53)이 하측으로 위치되었을 때 벤딩부(54)가 고정부(52)에 고정되므로 현가봉(53)을 상측방향으로 지지하게 된다. 그리고 지지부(33)는 전술한 바와 같이, 하우징(10)의 내부 상측 각 코너에 마련된 것으로, 여기에는 고정부(52)가 삽입 안착되어 자유롭게 움직일 수 있도록 반구형상의 삽입구(34)가 형성된다. 이 삽입구(34) 내부에는 고정부(52)의 움직임에 따른 손상을 방지하기 위한 마찰오일이 도포되어 있다. 마찰오일은 일종의 윤활제로서, 고정부(52)와 삽입구(34)의 마찰력을 감쇄시킬 수 있도록 고정부(52)와 삽입구(34) 사이에 소정치를 도포하는 것이 바람직하다.The fixing part 52 is provided in a hemispherical shape in which the hole 52a is perforated so that the bending part 54 of the suspension rod 53 can be inserted in the center thereof, so that the bending rod 53 is bent when the suspension rod 53 is positioned downward. Since the part 54 is fixed to the fixing part 52, the suspension rod 53 is supported upward. As described above, the support part 33 is provided at each inner upper corner of the housing 10, and a hemispherical insertion hole 34 is formed so that the fixing part 52 can be inserted and seated and freely moved. The insertion hole 34 is coated with a friction oil to prevent damage caused by the movement of the fixing portion 52. The friction oil is a kind of lubricant, and it is preferable to apply a predetermined value between the fixing portion 52 and the insertion hole 34 so as to reduce the frictional force between the fixing portion 52 and the insertion hole 34.

이와 같이 구성된 종래 세탁기에는 세탁물의 세탁 및 헹굼행정이 완료된 후 탈수행정이 수행되는데, 이 때 세탁물은 세탁과정에서 발생되는 교반작용에 의해 상당히 편심된 상태에서 탈수행정에 임하게 된다.In the conventional washing machine configured as described above, after the washing and rinsing cycles of the laundry are completed, the dehydration stroke is performed. At this time, the laundry faces the dehydration stroke in a state that is considerably eccentric by the stirring action generated in the washing process.

이러한 상태에서 탈수행정이 수행되면, 편심된 세탁물과 세탁조(31)의 회전에 의한 진동이 발생되고, 계속하여 진동은 수조(30)측으로 전달되고 현가장치(50)의 완충부(55)에 의해 감쇄된다. 즉, 수조(30)에 일체로 마련된 현가부(35)가 수조(30)와 같이 상하로 진동함에 따라, 방진고무(57)는 완충부(55) 벽면과 마찰하면서 승하강 운동하여 마찰력을 발생시킨다. 아울러 방진고무(57)와 완충부(55) 사이에 마련된 방진스프링(56)이 수축·이완되면서 진동을 감쇄시킨다.When the dehydration stroke is performed in such a state, vibration caused by the rotation of the eccentric laundry and the washing tank 31 is generated, and the vibration is transmitted to the water tank 30 side by the buffer unit 55 of the suspension device 50. Is attenuated. That is, as the suspension part 35 integrally provided in the water tank 30 vibrates up and down like the water tank 30, the anti-vibration rubber 57 moves up and down while rubbing against the wall of the buffer part 55 to generate frictional force. Let's do it. In addition, the vibration damping spring 56 provided between the anti-vibration rubber 57 and the shock absorbing portion 55 contracts and relaxes to reduce vibration.

한편, 지지부(33)의 삽입구(34)에 삽입 안착되어 있는 고정부(52)는 삽입부(34)와의 사이에 마련된 마찰오일로 인해 마찰이 감쇄된 상태에서 현가봉(53)의 이동에 따라 자유롭게 움직이면서 수조(34)를 현가시킨다.On the other hand, the fixing portion 52 is inserted and seated in the insertion hole 34 of the support portion 33 in accordance with the movement of the suspension rod 53 in a state where the friction is attenuated by the friction oil provided between the insertion portion 34 Suspending the water tank 34 while moving freely.

그러나, 이러한 종래 세탁기는 장기간 사용함에 따라 지지부(33)의 삽입구(34)에 도포한 마찰오일이 지지부(33)와 고정부(52)의 지속적인 마찰작용으로 인해 외부로 빠져나가거나 증발된다. 이에 따라 지지부(33)와 고정부(52)가 직접적으로 마찰 접촉하게 되고, 이것에 의해 소음과 진동을 수반한 마모가 발생되는 문제점이 있다.However, in such a conventional washing machine, the friction oil applied to the insertion hole 34 of the support part 33 escapes or evaporates to the outside due to the continuous friction action of the support part 33 and the fixing part 52 with a long time use. As a result, the support part 33 and the fixing part 52 are in direct friction contact with each other, thereby causing a problem in that wear accompanied by noise and vibration occurs.

본 발명은 이러한 문제점을 해결하기 위한 것으로, 본 발명의 목적은 수조를 현가시키는 현가봉에 마련된 고정부와 하우징에 마련되어 고정부가 삽입 안착되는 지지부 사이에 지속적으로 마찰오일을 공급함으로써, 세탁기의 장기간 사용으로 인한 고정부와 지지부의 마모를 방지함과 동시에 소음과 진동을 보다 저감시킬 수 있는 현가장치 급유수단을 갖춘 세탁기를 제공하는 것이다.The present invention is to solve such a problem, an object of the present invention is to provide a long-term use of the washing machine by continuously supplying the friction oil between the fixing portion provided on the suspension rod suspending the tank and the support portion provided in the housing is inserted and seated It is to provide a washing machine having a suspension lubrication means that can prevent the wear of the fixing portion and the support portion and at the same time further reduce noise and vibration.

And the side surface of the oil pocket 200 is formed with a coupling surface 230 of the outward flange type, it is coupled to the upper surface of the support 133.

다음에는 이와 같이 구성된 본 발명에 따른 현가장치 급유수단의 작용 및 효과를 설명한다.Next, the operation and effects of the suspension oil supply means according to the invention configured as described above will be described.

우선, 세탁물을 투입한 후 뚜껑(121)을 닫고 세탁기를 작동시키면, 세탁물 양에 따라 물이 수조(130)에 저장된다. 적당량의 물이 담수되면, 모터(141)가 구동되어 펄세이터(132)가 정역 회전함으로써 세탁물이 세탁조(131) 내부에서 세탁되는 세탁 및 헹굼행정이 반복적으로 수행된다.First, after the laundry is put in and the lid 121 is closed and the washing machine is operated, water is stored in the water tank 130 according to the amount of laundry. When the appropriate amount of water is fresh water, the motor 141 is driven to rotate the pulsator 132 forward and reverse to repeatedly perform the washing and rinsing stroke in which the laundry is washed inside the washing tank 131.

그리고 세탁행정이 종료되면, 세탁조(131)와 펄세이터(132)를 일방향으로 고속 회전시켜 세탁물을 탈수시키는 탈수행정이 수행된다.When the washing operation is completed, the washing tank 131 and the pulsator 132 are rotated at high speed in one direction to perform a dehydration operation to dehydrate the laundry.

이 때, 세탁물은 세탁과정에서 발생되는 교반작용에 의해 상당한 편심된 상태에서 탈수행정에 임하게 된다. 이러한 상태에서 탈수행정이 진행되면, 편심된 세탁물과 세탁조(131)의 회전에 의한 진동이 발생되고, 이 진동은 현가장치(150)의 현가봉(153)을 통해 매달려 설치된 수조(130)로 전달되며 완충부(155)에 의해 줄어든다.At this time, the laundry is dehydrated in a considerable eccentric state by the stirring action generated during the washing process. When the dehydration administration proceeds in this state, vibration caused by the rotation of the eccentric laundry and the washing tank 131 is generated, and the vibration is transmitted to the water tank 130 suspended through the suspension rod 153 of the suspension device 150. And is reduced by the buffer 155.

즉, 수조(130)와 일체로 형성된 현가부(135)가 상,하방향으로 진동함에 따라, 이에 결합된 완충부(155) 내부에서는 방진고무(157)가 벽면과 접촉된 상태로 승하강 운동하여 마찰력을 발생시키며, 아울러 방진스프링(156)이 수축, 이완되면서 진동이 저감된다.That is, as the suspension part 135 formed integrally with the water tank 130 vibrates in the up and down direction, the vibration-resistant rubber 157 moves up and down in contact with the wall in the buffer part 155 coupled thereto. To generate a frictional force, and also reduce vibration while the anti-vibration spring 156 contracts and relaxes.

한편, 현가봉(153)의 상단이 고정된 고정부(152)는 삽입구(134)내에서 자유롭게 움직이게 되는데, 여기에는 오일포켓(200)에서 급유되는 마찰오일(100)에 의해 마찰이 감소된다. 즉, 마찰오일(100)이 급유관(220)을 통해 하측방향으로 공급되는데, 평상 시에는 소정의 점도를 갖기 때문에 서서히 공급되며, 세탁기의 가동으로 진동이 발생될 때에는 급유량이 증가한다. 따라서 지지부(133)의 삽입구(134)와 고정부(152)의 접촉면에는 급유되는 마찰오일에 의해 마찰력이 감소되며, 이것에 의해 현가봉(153)의 움직임에 따라 고정부(152) 역시 자유롭게 움직이게 된다.On the other hand, the fixing portion 152 of the upper end of the suspension rod 153 is free to move in the insertion hole 134, where the friction is reduced by the friction oil 100 lubricated by the oil pocket 200. That is, the friction oil 100 is supplied in a downward direction through the oil supply pipe 220. Since the friction oil 100 usually has a predetermined viscosity, the friction oil 100 is gradually supplied, and when the vibration is generated by the operation of the washing machine, the oil supply amount increases. Therefore, the friction force is reduced by the friction oil lubricated to the contact surface between the insertion hole 134 and the fixing portion 152 of the support portion 133, thereby allowing the fixing portion 152 to move freely as the suspension rod 153 moves. do.

이상에서 상세히 설명한 바와 같이, 본 발명에 따른 현가장치 급유수단을 갖춘 세탁기에 의하면, 지지부 상부에 설치되며 내부에 저장실이 형성되고 하면에 지지부와 고정부를 향하도록 한쌍의 급유관이 마련된 오일포켓과, 오일포켓의 저장실에 다량 저장되며 급유관을 통해 빠져나가는 마찰오일을 구비하고 있어서, 고정부가 안착되는 지지부 상부에 지속적으로 마찰오일이 공급된다. 이에 따라 세탁기의 장기간 사용으로 인한 고정부와 지지부의 마모손상이 방지되며, 아울러 세탁기의 작동소음과 진동이 보다 저감됨으로써 전체적인 세탁기의 제품 신뢰성이 향상되는 이점이 있다.As described above in detail, according to the washing machine equipped with the suspension oil supply means according to the present invention, the oil pocket provided with a pair of oil supply pipes are installed on the upper part of the support and formed inside the storage compartment and facing the support and the fixing part on the lower surface; In addition, since a large amount of friction oil is stored in the storage compartment of the oil pocket and exits through the oil supply pipe, the friction oil is continuously supplied to the upper part of the support on which the fixing part is seated. Accordingly, the wear and tear of the fixing part and the support part are prevented due to the long-term use of the washing machine, and the operating noise and vibration of the washing machine are further reduced, thereby improving the overall product reliability of the washing machine.
