본 고안은 진공청소기에 관한 것으로 특히, 어코스틱필터 벽에 방진구를 형성하여 공기의 완만한 유동을 유도하고 난류 유동 소음을 최소화 한 진공청소기의 소음 저감 구조에 관한 것이다.The present invention relates to a vacuum cleaner, and more particularly, to a noise reduction structure of a vacuum cleaner in which a dustproof port is formed on an acoustic filter wall to induce a gentle flow of air and minimize turbulent flow noise.

종래에는 진공청소기에서 발생되는 소음을 저감 시키기 위해 제1도에 도시되는 바와 같이 본체(1) 내부에 형성된 팬모터(4)를 완전히 밀폐시켜 발생되는 소음을 차음 및 흡음시킬 수 있도록 소음격리부재(3)와 어코스틱필터(1)를 일체로 형성하였다.Conventionally, as shown in FIG. 1, in order to reduce the noise generated in the vacuum cleaner, the fan motor 4 formed inside the main body 1 is completely sealed, so as to sound-induce and absorb sound generated by the noise isolating member ( 3) and the acoustic filter 1 were integrally formed.

상기와 같은 종래의 진공청소기는 본체(1)에 전원이 인가되면 상기 본체(1) 내부에 형성된 팬모터(4)가 공기를 흡입하는 과정에서 소음이 크게 발생하게 되는데 이때 발생된 소음은 완전히 팬모터(4)를 밀폐한 어코스틱필터(2)와 소음격리부재(1)에 의해 소음이 저감된다.When the conventional vacuum cleaner as described above, power is applied to the main body 1, the noise is generated in the process of inhaling air from the fan motor 4 formed inside the main body 1, and the generated noise is completely fan Noise is reduced by the acoustic filter 2 and the noise isolating member 1 sealing the motor 4.

그러나, 소음격리부재(3)에서 나오는 공기가 어코스틱필터(2)로 유입됨과 동시에 내벽에 부딪히면서 저주파의 진동음을 발생시킬 뿐만 아니라, 이로 인해 공기 유동 흐름이 원만하지 못하여 난류소음을 발생 기키는 문제점이 있었다.However, the air from the noise isolating member (3) is introduced into the acoustic filter (2) and at the same time hit the inner wall to generate a low frequency vibration sound, due to which the air flow flow is not smooth, causing turbulent noise There was this.

본 고안의 목적은 상기와 같은 종래의 문제점을 해결하기 위해 안출한 것으로서, 어코스틱필터의 벽에 방진구를 형성하여 공기의 완만한 유동을 유도하여 난류 유동 소음을 최소화 시킨 진공청소기의 소음 저감 구조를 제공 하는데 있다.The object of the present invention is to solve the above-mentioned problems, the noise reduction structure of the vacuum cleaner to minimize the turbulent flow noise by inducing a gentle flow of air by forming a dustproof port on the wall of the acoustic filter To provide.

이하 첨부 도면에 의거하여 기술적 구성을 상세히 설명하면 다음과 같다.Hereinafter, the technical configuration will be described in detail with reference to the accompanying drawings.

본 고안은 제2도에 도시되는 바와 같이 본체(10) 내부에 형성된 팬모터(11)에서 발생되는 소음을 차음 및 흡음시키는 소음격리부재(13)와 어코스틱필터(12)에 있어서, 상기 어코스틱필터(12)의 내벽에 부딪치는 공기의 진동음을 방지하고 공기의 흐름을 용이하게 할수 있도록 어코스틱필터(12)의 한쪽 벽면에 방진구(20)를 설치하는 것을 그 기술적 구성상을 기본 특징으로 한다.The present invention, in the noise isolating member 13 and the acoustic filter 12 for insulating and sound-absorbing noise generated in the fan motor 11 formed inside the main body 10, as shown in FIG. The basic feature of the technical configuration is that the dustproof port 20 is installed on one wall of the acoustic filter 12 to prevent the vibration sound of the air that hits the inner wall of the stick filter 12 and to facilitate the flow of the air. It is done.

여기에서, 상기 방진구(20)는 공기의 유동을 원만하게 반구형상으로 하고, 어코스틱필터(12)의 내측으로 돌출되게 한다.Here, the anti-vibration opening 20 smoothly flows the air into a hemispherical shape, and protrudes into the acoustic filter 12.

이와 같이 구성된 본 고안은 진공청소기에 전윈이 인가되면 본체(10)내부에 형성된 팬모터(11)가 공기를 흡입하는 과정에서 소음이 크게 발생하게 되는데 이때 발생된 소음은 완전히 밀폐된 어코스틱필터(12)와 소음격리부재(13)에 의해 소음이 저감된다.When the electric power is applied to the vacuum cleaner, the present invention configured as described above generates a large noise in the process of sucking the air from the fan motor 11 formed in the main body 10. The generated noise is a completely sealed acoustic filter ( 12) and the noise isolating member 13 reduce noise.

이때 공기가 어코스틱필터(12)로 유입됨과 동시에 내벽에 형성된 방진구(20)에 부딪히면서 완만한 공기 유동이 형성되면서 저주파의 진동음과 난류소음을 저감 한다.At this time, while the air flows into the acoustic filter 12 and hits the dustproof port 20 formed on the inner wall, a gentle air flow is formed, thereby reducing low frequency vibration noise and turbulent noise.

이상에서 살펴본 바와 같이 본 고안은 어코스틱필터 벽에 방진구를 형성 함으로서, 공기의 완만한 유동을 형성하고 이로 인해 난류유동 소음 및 저주파 진동음을 최소화 한 매우 유용한 고안이다.As described above, the present invention is a very useful design that forms a gentle flow of air, thereby minimizing turbulent flow noise and low frequency vibration by forming a dustproof port on the acoustic filter wall.
