Description

세탁기의 드레인펌프 진동방지장치Drain pump vibration damper of washing machine

본 고안은 세탁기의 드레인펌프 진동방지장치에 관한 것으로서, 특히 드레인펌프로부터 발생되는 진동이 외체로 전달되는 것을 최소한으로 줄여줄 수 있도록 한 세탁기의 드레인펌프 진동방지장치에 관한 것이다.The present invention relates to a drain pump vibration preventing device of a washing machine, and more particularly, to a drain pump vibration preventing device of a washing machine to reduce the vibration generated from the drain pump to the outside to a minimum.

일반적으로 드레인펌프는 모터의 구동에 의해 송풍팬을 회전시켜 주어 세탁 및 헹굼시 세탁수를 순환관으로 공급시켜 주어 순환이 될 수 있도록 하고 배수시에는 세탁수를 배수관으로 공급이 되도록 하여 배수가 이루어질 수 있도록 하는 것으로서, 이러한 드레인펌프는 외체의 내부 하단 적당한 지점에 위치하도록 한 상태에서 체결보울트를 사용하여 드레인펌프가 외체에 견고히 고정이 되도록 하고 있다.In general, the drain pump rotates the blower fan by driving the motor to supply the washing water to the circulation pipe during washing and rinsing so that the water can be circulated. As such, the drain pump is used to fasten the drain pump to the outer body by using a fastening bolt in a state where it is located at a suitable point at the inner lower end of the outer body.

그러한 드레인펌프는 모터의 구동력에 의해 회전되는 송풍팬에 의해 세탁수를 강제로 흡입함과 동시에 이를 토출시켜 주게 되는데, 이때 상기 모터의 구동시 이로부터 진동 및 소음이 발생하게 되어 이의 진동 및 소음이 외체를 통해 외부로 전달이 되어 제품의 신뢰성을 떨어뜨리게 됨에 의해 방진고무를 사용하여 외부로 전달되는 진동 및 소음을 최소한으로 줄여주고 있다.Such a drain pump forcibly sucks and discharges the washing water by the blowing fan rotated by the driving force of the motor, and at the same time, when the motor is driven, vibration and noise are generated therefrom, thereby causing vibration and noise. It is transmitted to the outside through the outside to reduce the reliability of the product, thereby using vibration-resistant rubber to minimize the vibration and noise transmitted to the outside.

즉, 종래의 드레인펌프 진동방지장치는 제3도에서와 같이 외체(10)와 드레인펌프(20)의 고정편(21) 사이에 방진고무(30)가 위치하도록 한 상태에서 이들을 체결보울트(40)로 관통시켜 준 뒤 너트(41)로 견고히 고정시켜 줌으로서, 드레인펌프로부터 발생된 진동은 이와 일체로 구성된 고정편을 통해 방진고무를 거치면서 진동이 소멸되도록 되어 있는 것이다.That is, in the conventional drain pump vibration preventing device, as shown in FIG. 3, the fastening bolt 40 is mounted in a state in which the anti-vibration rubber 30 is positioned between the outer body 10 and the fixing piece 21 of the drain pump 20. By passing through) and firmly fixed with a nut 41, the vibration generated from the drain pump is to be dissipated while passing the vibration-proof rubber through the fixing piece formed integrally therewith.

그러나 상기와 같은 종래의 진동방지장치는 드레인펌프의 고정편과 외체의 사이에단순히 평판상의 방진고무가 위치하도록 한 상태에서 이들을 체결보울트로 관통시켜 이에 의해 드레인펌프가 외체와 결합되도록 하여 고정편으로 전달된 진동이 방진고무에 의해 소멸되도록 하여 외체로 전달되는 것을 방지하는 것으로, 상기 고정편이 방진고무에 의해 외체와는 직접적으로 접지가 되지는 않고 있으나 이들을 체결고정시켜주는 체결보울트가 외체로 부터 방진고무를 거쳐 고정편과 연결되어 있는 상태로 드레인펌프로 부터 발생된 진동이 고정편을 통해 방진고무를 거치는 진동은 방진고무의 흡수력에 의해 소멸이 되고 고정편과 직접적으로 연결된 체결보울트로 전달되는 진동은 이와 연통된 외체로 전달되어 소음이 발생하게 되어 본래의 목적하는 진동 및 소음을 충분히 잡아주지 못하게 되는 단점이 있으며 이로인해 제품의 신뢰성을 떨어뜨리게 되는 등의 결함이 있었던 것이다.However, the conventional vibration damping device as described above allows the drain pump to be coupled to the outer body by penetrating them with a fastening bolt in a state in which a flat dust-proof rubber is positioned between the fixed piece of the drain pump and the outer body. The vibration is transmitted to the external body to be extinguished by the anti-vibration rubber, and the fixing piece is not directly grounded to the external body by the anti-vibration rubber, but the fastening bolt for fastening and fastening them is dustproof from the external body. The vibration generated from the drain pump through the rubber while being connected to the stationary piece via rubber is extinguished by the absorption force of the dustproof rubber and is transmitted to the fastening bolt directly connected to the stationary piece. Is transmitted to the external body in communication with this, and noise is generated. There is a drawback of not being able to sufficiently grab vibration and noise, which leads to a defect such as lowering the reliability of the product.

본 고안의 목적은 외체와 드레인펌프의 고정편을 체결시켜 주는 체결보울트가 이들과 직접적으로 접촉되지 않도록 한 상태에서 결합시켜 주어 드레인펌프로 부터 발생된 진동이 외체로 전달이 되지 않고 완전히 소멸될 수 있도록 하여 진동 및 소음방지 효율을 향상시켜 줄 수 있도록 함과 아울러, 이로인해 제품의 신뢰성을 높여줄 수 있도록 하는 세탁기의 드레인펌프 진동방지장치를 제공함에 있다.The purpose of the present invention is to connect the fastening bolts that fasten the outer body and the fixing piece of the drain pump so that they do not come into direct contact with them so that the vibration generated from the drain pump can be completely eliminated without being transmitted to the external body. The present invention provides a drain pump vibration preventing device for a washing machine to improve vibration and noise prevention efficiency, and to thereby increase the reliability of the product.
