Description
본 고안은 세탁기의 드레인펌프 진동방지장치에 관한 것으로, 특히 세탁수를 외부로 배출시 드레인모터로부터 발생되는 진동 및 이에 따른 소음이 세탁기 외체로 전달되는 것을 최대한 줄여 제품의 품질을 향상시키게 되는 것이다.The present invention relates to an anti-vibration device for a drain pump of a washing machine. In particular, the vibration and the noise generated from the drain motor when the washing water is discharged to the outside are reduced to the maximum to reduce the transmission of the washing machine to the outside of the washing machine to improve the quality of the product.
일반적으로 세탁기의 드레인펌프는 모터의 구동에 의해 송풍팬을 회전시켜 세탁 및 헹굼시 세탁수를 순환관으로 공급시켜 순환이 이루어지도록 하게 되고, 배수시에는 세탁수를 배수관으로 공급되도록 하여 배수가 이루어질수 있도록 하는 것이다. 이러한 드레인펌프는 외체의 내부 하단 지점에 위치되도록 볼트로써 세탁기의 외체에 견고하게 체결 고정되도록 하였다.In general, the drain pump of the washing machine rotates the blower fan by driving the motor to supply the washing water to the circulation pipe during washing and rinsing so that the circulation is performed. To ensure that This drain pump is to be firmly fastened to the outer body of the washing machine by bolts to be located at the inner bottom point of the outer body.
한편, 드레인펌프는 모터의 구동에 의해 발생되는 진동이 외체로 그대로 전달되어 제품의 신뢰성이 떨어짐을 방지하기 위한 고무재로 이루어진 방지부재를 사용하여 외체로 전달되는 진동을 완충시켜 이에 따른 소음을 저감시키게 된다.On the other hand, the drain pump buffers the vibration transmitted to the external body by using the prevention member made of a rubber material to prevent the vibration generated by the drive of the motor is transmitted to the external as it is to reduce the reliability of the product to reduce the noise accordingly Let's go.
이러한 종래 드레인펌프의 진동을 방지하기 위한 장치는, 도 1에 도시된 바와 같이 세탁기 외체(100)와 드레인펌프(200)의 고정브라켓(210) 사이에 고무재질의 방진부재(300)가 안착되고, 이를 체결볼트(400)로써 관통시킨 다음, 이를 너트(410)로써 체결시키게 됨으로써 드레인펌프(200)로부터 발생되는 진동이 완충되어 소음이 저감된다.The apparatus for preventing the vibration of the conventional drain pump, as shown in Figure 1, the dustproof member 300 of the rubber material is seated between the washing machine outer body 100 and the fixing bracket 210 of the drain pump 200 Then, it is penetrated by the fastening bolt 400, and then fastened by the nut 410, the vibration generated from the drain pump 200 is buffered to reduce the noise.
즉, 드레인펌프(200)로부터 발생되는 진동이 고정브라켓(210)을 거치면서 고무재질의 방진부재(300)로 전달되어 진동이 완충되어 소음이 저감되는 것이다.That is, the vibration generated from the drain pump 200 is transmitted to the dustproof member 300 of the rubber material while passing through the fixing bracket 210, so that the vibration is buffered to reduce noise.

That is, because the fixed bracket is not directly grounded with the outer body by the anti-vibration member, the vibration of the drain pump transmitted to the anti-vibration member via the fixed bracket is buffered by the anti-vibration member, and is fastened through the fastening bolt directly coupled to the fixed bracket. Since the transmitted vibration is transmitted to the outside as it is, vibration and noise are generated to reduce the reliability of the product and shorten the life of the product.
본 고안은 이와 같은 종래의 문제점을 해결하기 위하여 안출된 것으로, 본 고안은 드레임펌프의 진동이 세탁기의 외체로 전달되는 것을 최대한 방지하여 제품의 신뢰성 및 수명을 연장시키는 세탁기의 드레인펌프 진동방지장치를 제공하는 데 그 목적이 있다.The present invention is devised to solve such a conventional problem, the present invention is to prevent the vibration of the drain pump to the outside of the washing machine drain pump vibration preventing device of the washing machine to extend the reliability and life of the product as much as possible The purpose is to provide.

도 2 및 도 3에 도시된 바와 같이, 통상적인 세탁기는 외체(10) 내부에 구비되어 세탁수가 담겨지는 저수조(20)와; 저수조(20) 내부에 구비되어 세탁물이 담겨지는 세탁조(30)와; 세탁조(30) 내부 하단에 구비되어 세탁수를 회류시키는 회전날개(40)와; 저수조(20) 하단에 구비되어 세탁행정에 따라 세탁조(30) 및 회전날개(40)를 회전시키는 구동부(50)와; 외체(10) 내부 하단의 적정위치에 설치되어 세탁행정에 따라 세탁수를 순환 및 배수시키는 드레인펌프(60)로 이루어진다.As shown in Figures 2 and 3, a conventional washing machine is provided with a reservoir 20 in which the washing water is contained in the outer body 10; A washing tub 30 provided inside the storage tank 20 in which laundry is contained; A rotary blade 40 provided at the lower end of the washing tub 30 to rotate the washing water; A driving unit 50 provided at the bottom of the reservoir 20 to rotate the washing tub 30 and the rotary blade 40 according to the washing stroke; Installed at the lower end of the outer body 10 is made of a drain pump 60 for circulating and draining the washing water according to the washing stroke.
이때, 드레인펌프(60) 하부 양측의 고정브라켓(62)과 외체(10) 사이에는 체결볼트(70)와 너트(72)의 체결력으로써 방진부재(80)가 체결 고정되어 드레임펌프(60)에서 발생되는 진동을 완충시키게 된다.At this time, between the fixing bracket 62 and the outer body 10 at both sides of the drain pump 60, the dustproof member 80 is fastened and fixed by the fastening force of the fastening bolt 70 and the nut 72 to the drain pump 60. It will dampen the vibration generated in the.
상기 방진부재(80)는 적정 완충력과 흡수력을 갖는 고무재로 이루어지고, 그 중앙 영역에는 체결볼트(70)가 관통되는 수직관통공(82)이 형성되며, 중앙 외주연에는 적정 깊이를 유지하여 고정브라켓(62)의 통공(64)에 삽입되는 환형요홈(84)이 형성된다.The anti-vibration member 80 is made of a rubber material having a proper buffering force and absorbing power, and a vertical through hole 82 through which the fastening bolt 70 penetrates is formed in a central region thereof, and maintains a proper depth at the center outer circumference. An annular recess 84 is inserted into the through hole 64 of the fixing bracket 62.
이와 같이 구성된 본 고안은 방진부재(80)를 드레인펌프(60)의 고정브라켓(62)에 형성된 통공(64)에 끼우게 된다. 즉, 방진부재(80) 외주연의 환형요홈(84)를 고정브라켓(62)의 통공(64)에 억지로 끼우게 되면, 방진부재(80) 외주연이 재질의 특성상 찌그러지면서 환형요홈(84)이 고정브라켓(62)의 통공(64)에밀착되게 끼워지게 된다.The present invention configured as described above is to insert the dustproof member 80 in the through hole 64 formed in the fixing bracket 62 of the drain pump 60. That is, when the annular groove 84 of the outer periphery of the dustproof member 80 is forcibly inserted into the through hole 64 of the fixing bracket 62, the outer periphery of the dustproof member 80 is distorted due to the characteristics of the material, and the annular groove 84 The fixing bracket 62 is fitted in close contact with the through hole 64.
그러면, 방진부재(80)의 수직관통공(82)과 외체(10)의 바닥면에 형성된 체결공(11)이 일치된다.Then, the vertical through hole 82 of the dustproof member 80 and the fastening hole 11 formed on the bottom surface of the outer body 10 coincide with each other.
그 다음으로 외체(10)의 체결공(11)과 방진부재(80)의 수직관통공(82)을 통하여 체결볼트(80)를 관통시킨 다음, 방진부재(80) 상부로 돌출된 체결볼트(80)에 너트(72)를 체결시키면, 드레인펌프(60)가 외체(10)에 견고하게 체결 고정된다.Next, the fastening bolt 80 passes through the fastening hole 11 of the outer body 10 and the vertical through hole 82 of the anti-vibration member 80, and then the fastening bolt protruding upward from the anti-vibration member 80 ( When the nut 72 is fastened to the 80, the drain pump 60 is firmly fastened to the outer body 10.
이러한 상태에서 세탁기의 세탁 및 탈수행정으로 수행하게 된다. 그러면, 세탁물의 세탁 및 배수시 드레인펌프(60)가 동작되어, 즉 모터(미도시)의 구동에 의해 송풍팬(미도시)이 회전되어 저수조(20)에 담수된 세탁수를 흡입된다.In this state, washing and dehydrating operations of the washing machine are performed. Then, when washing and draining the laundry, the drain pump 60 is operated, that is, a blower fan (not shown) is rotated by the driving of a motor (not shown) to suck the wash water freshly stored in the reservoir 20.
이와 동시에 흡입된 세탁수를 세탁시에는 순환관(미도시)를 통하여 순환시켜주어 세탁물의 세탁효율을 향상시켜주고, 배수시에는 배수관(미도시)를 통해 외부로 원활한 배수가 이루어지도록 하게 된다.At the same time, the suctioned washing water is circulated through a circulation tube (not shown) to improve the washing efficiency of the laundry, and when draining, smooth drainage is made to the outside through a drain pipe (not shown).
이때, 드레인펌프(60)가 모터로부터 발생되는 진동이 고정브라켓(62)을 통해 고무재질의 방진부재(80)로 전달되어 완충되고, 이에 발생되는 소음이 저감된다.At this time, the vibration generated by the drain pump 60 is transmitted to the anti-vibration member 80 of the rubber material through the fixing bracket 62, and the noise generated therein is reduced.
즉, 체결볼트(70)와 너트(72)가 고정브라켓(62)과 직접 접촉되지 않고, 방진부재(80)에 접촉되어 있어, 고정브라켓(62)을 통하여 발생되는 진동이 방진부재(80)로 전달되어 완충됨으로써 외체(10)로 전달되지 않게 되고, 진동에 의한 소음이 저감된다.That is, the fastening bolt 70 and the nut 72 are not in direct contact with the fixing bracket 62, but are in contact with the dustproof member 80, so that vibration generated through the fixing bracket 62 is prevented. As it is transmitted to and buffered, it is not transmitted to the outer body 10, and noise due to vibration is reduced.
이상에서 상술한 본 고안에 의하면, 세탁기의 외체와 드레인펌프의 고정브라켓을 상호 결합시키는 체결볼트 및 너트가 고정브라켓과 직접적으로 접촉되지 않고, 고무재질의 방진부재에 삽입되어 있어 세탁기 사용시 드레인펌프에서 발생되는 진동이 방진부재로 전달되어 완충 및 흡수되어 외체로 전달되지 못하게 되고, 이로인해 발생되는 소음이 저감되어 제품의 신뢰성을 향상시키는 동시에 제품의 수명을 연장시키게 되는 효과가 제공된다.According to the present invention described above, the fastening bolts and nuts for coupling the outer bracket of the washing machine and the fixing bracket of the drain pump are not directly in contact with the fixing bracket, but are inserted into the dustproof member made of rubber material. The generated vibration is transmitted to the dustproof member to be absorbed and absorbed and not transmitted to the outside, thereby reducing the noise generated thereby improving the reliability of the product and at the same time extending the life of the product.
