본 발명은 진공청소기에 관한 것으로, 특히 공기를 흡입하는 구동모터에서 발생되는 소음을 제거하도록 하는 진공청소기의 방음장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vacuum cleaner, and more particularly, to a soundproofing device for a vacuum cleaner for removing noise generated by a driving motor that sucks air.

종래 진공청소기의 방음장치는 제2도에 도시한 바와 같이, 몸체케이싱(1)의 내부에는 공기를 흡입하는 구동모타(2)가 장착되어 있고, 이 구동모터(2)의 외부에는 패킹(3)이 체결되어 있으며, 이 패킹(3)의 외부에는 다시 소음을 줄여주는 사운드리버(4)가 체결되어 있고, 상기 몸체케이싱(1)에는 착탈가능한 배기필터(5)가 체결되어 있다.As shown in FIG. 2, the soundproofing device of the conventional vacuum cleaner has a drive motor 2 for sucking air inside the body casing 1, and a packing (3) outside the drive motor (2). Is fastened to the outside of the packing (3), and a sound river (4) for reducing noise is fastened, and a detachable exhaust filter (5) is fastened to the body casing (1).

이러한 종래 진공청소기의 방음장치는 제2도에 도시한 바와 같이, 몸체케이싱(1)의 내부에 장착된 구동모터(2)의 구동으로 공기가 흡입되면, 이 흡입되는 공기에 포함된 오물은 필터(도면 미도시)에서 제거되었으며, 이 오물이 제거된 공기는 구동모터(2)를 감싸는 패킹(3)과 사운드라버(4)를 차례로 경유하여 몸체케이싱(1)에 체결되어 있는 배기필터(5)를 통하여 외부에 배출되었으며, 이때 구동모터(2)에서 발생된 소음은 패킹(3)를 통하여 감소되었고, 이렇게 감소된 소음은 다시 사운드라버(4)와 배기필터(5)를 통하여 더욱 감소되었으며, 도면 중 화살표는 공기의 흐름을 나타낸다.As shown in FIG. 2, when the air intake is driven by the driving motor 2 mounted inside the body casing 1, the dust contained in the sucked air is filtered. (Not shown), the air from which the dirt is removed is exhaust filter (5) fastened to the body casing (1) via the packing (3) surrounding the drive motor (2) and the sound rubber (4) in turn. The noise generated by the driving motor 2 is reduced through the packing 3, and the noise is further reduced through the sound lever 4 and the exhaust filter 5. Arrows in the drawing indicate the flow of air.

그러나, 이와 같은 진공청소기의 방음장치는, 소음을 발생시키는 구동모터 주위에 패킹과 사운드라버가 밀집되어 체결되었기 때문에, 상기 구동모터에 과부하가 발생되었고, 이로 인하여 구동모터의 성능이 저하되었다.However, in the soundproofing device of the vacuum cleaner, since the packing and the sound lever are densely fastened around the driving motor generating noise, the driving motor is overloaded, resulting in a decrease in the performance of the driving motor.

본 발명은 상기의 문제점을 해결하기 위한 것으로, 몸체케이싱에 오물이 제거된 공기가 통과되도록 하는 별도의 버퍼연장관을 형성하고, 이 버퍼연장관에 소음을 줄여주는 방음용 필터들이 다수개 설치되도록 하여, 구동모터에서 발생되는 소음이 흡수되도록 하는 진공청소기의 방음장차를 제공하고자 한다.The present invention is to solve the above problems, to form a separate buffer extension tube for passing the air to remove the dirt in the body casing, so that a plurality of sound-proof filters are installed in the buffer extension tube to reduce noise, To provide a soundproof vehicle vacuum cleaner to absorb the noise generated by the drive motor.
