본 고안은 청소기의 소음저감 연장관에 관한 것으로 보다 상세히는 연장관에서 발생하는 소음을 위한 제어하는 공명기와 압력맥동을 저감시키는 흡음재를 설치한 흡음파이프구조에 관한 것이다.The present invention relates to a noise reduction extension pipe of a cleaner, and more particularly, to a sound absorption pipe structure including a resonator for controlling noise generated in the extension pipe and a sound absorbing material for reducing pressure pulsation.

일반적인 진공청소기 구조는 제1도에서 보인 바와같이 흡입장치를 갖고 흡입력으로 먼지를 수집 수용하는 일정용적의 공간이 있는 몸체(1)와, 몸체(1)에 연결되어 유로를 형성하기 위한 플랙시블한 유연연장관(2)과, 유연연장관(2)과 연장관(4)을 연결하고 손으로 연장관을 각 방향으로 이동시키기 위한 손잡이(3)와, 길이의 장단조절을 위한 마디의 관 결합 구성체인 연장관(4) 및 먼지흡입부인 노즐(5)로 구성된다.A general vacuum cleaner structure has a body 1 having a suction device and a volume of space for collecting and accommodating dust by suction force, as shown in FIG. 1, and a flexible body connected to the body 1 to form a flow path. Flexible tube (2), the flexible tube (2) and the extension tube (4) connecting the handle (3) for moving the extension tube in each direction by hand, and the extension tube that is a pipe coupling configuration of the node for controlling the length and length of the extension ( 4) and the nozzle 5 which is a dust suction part.

진공청소기는 몸체(1)에서 팬 모터가 회전을 시작하여 먼지흡입과정이 진행되는데 모터의 회전에 따른 모터자체 소음과 모터의 회전수(RPM)와 날갯수를 곱한 주파수성분의 압력변동이 발생하면서 흡입노즐(5)을 통하여 흡입파이프인 연장관(4)을 지나고 유연연장관(2)을 통하여 몸체(1)로 전해진다.In the vacuum cleaner, the fan motor starts to rotate in the body (1), and the dust suction process is carried out. It passes through the suction pipe (5) through the extension pipe (4) of the suction pipe and is passed to the body (1) through the flexible extension pipe (2).

위 소음성분들은 흡입파이프인 연장관(4)을 지나면서 음이 방사 또는 몸체(1)측으로 이동되는데 이러한 소음성분이 연장관(4)에서 방사 또는 통과되는 현상을 방지하기 위해 종래에는 제2도의 (a)와(b)에서 보인 바와 같은 흡음파이프(4a)를 연장관(4)에 구성하였다.The noise components are moved to the radiation or the body 1 side while passing through the extension pipe (4) that is the suction pipe, which is conventionally shown in FIG. 2 to prevent the noise components from being radiated or passed through the extension pipe (4). The sound absorption pipe 4a as shown by (b) and (b) was comprised in the extension pipe 4. As shown in FIG.

(a)는 유로와 평행하게 흡음재 종류를 배치한 경우이고, (b)는 유로에 각각 방향으로 헬름(Helm)-홀쯔(Hoktz)공명기를 부착한 구조이다.(a) is a case where the kind of sound absorbing material is arrange | positioned in parallel with a flow path, (b) is a structure which attached the Helm-Hoktz resonator in the direction to each flow path.

(a)의 흡음재 배치구조와, (b)의 공명기 설치구조에 있어 유로의 방향에는 특성차이가 없다.There is no characteristic difference in the direction of the flow path between the sound absorbing material arrangement of (a) and the resonator mounting structure of (b).

(a)의 흡음파이프는 일단에 연장관고정부(6)를 두고 상대측에 연장관 삽입부(7)와 연장관보스(8)를 형성한 것이며 관경을 확장시켜 내부에 유로와 거의 평행하게 흡음재(9)를 설치한 구조로서 단순한 소음흡수 목적의 구성이고, (b)의 흡음파이프는 내경 유로 방향에 수직으로 헬름홀쯔 공명부(10)와, 유체흐름방향에 대하여 무방향성과 점(Point)공명소스를 가진 헬름홀쯔 공명입구(11)로 구성된 헬름-홀쯔 공면기를 설치한 것으로 일단에 연장관 고정부(6)와, 상대측에 연장관삽입부(7)및 연장관보스(8)를 두고 있다.The sound absorbing pipe of (a) is provided with an extension pipe fixing part 6 at one end and an extension pipe inserting portion 7 and an extension pipe boss 8 formed at the opposite side. The sound absorbing material 9 is substantially parallel to the flow path inside the tube by extending the diameter. The sound absorbing pipe of (b) has a Helmholtz resonance section 10 perpendicular to the inner diameter flow path and a non-directional and point resonance source with respect to the fluid flow direction. The Helm-Holtz coplanar machine composed of the excited Helmholtz resonance inlet 11 is provided, and the extension tube fixing part 6 is provided at one end, and the extension tube insertion part 7 and the extension tube boss 8 are provided at the opposite side.

제3도는 헬름-홀쯔 공명기의 설치구조를 보인 것으로, V : 체적, L : 공명기 길이입구, Sc : 공명구 입구면적, C : 응속일때,로 하여 모터의 회전주파수 성분이나 팬조화 소음성분을 맞추어 구성할 수 있도록 하였으나 소음저감폭이 적다.3 shows the installation structure of the Helm-Holtz resonator, where V is the volume, L is the length of the resonator inlet, Sc is the area of the inlet of the resonator, and C is the condensation. It can be configured to match the rotational frequency component of the motor or the noise component of the fan harmonic, but the noise reduction is small.

이러한 헬름-홀쯔 타입의 공명기는 그 자체 특성상 소음주파수를 이론적으로 저감이 가능하지만 유체흐름 방향에 대하여 무방향성과 점(Point)공명소스로 이루어진 공명기의 공명입구(11)가 작아지게 되어 소음저감 효과가 떨어지게 되는 것이다.The Helm-Holtz type resonator can theoretically reduce the noise frequency due to its own characteristics, but the resonance inlet 11 of the resonator composed of non-directionality and a point resonance source with respect to the direction of fluid flow becomes small, thereby reducing noise. Will fall.

또다른 흡음재(9)를 통한 단순한 소음흡수 구조는 응속이 빠르면 소음이 충분히 흡수되지 못하고 흡음재를 그대로 통과하게 되어 소음저감효율이 떨어진다.Simple sound absorbing structure through another sound absorbing material (9) is a fast response, the sound is not absorbed sufficiently, passes through the sound absorbing material as it is, noise reduction efficiency is lowered.

이와같은 종래의 연장관(4)의 흡음파이프(4a)구조는 유로가 형성되면서 발생하는 소음을 억제 저감시키도록 되어 있었으나 소음저감 효과가 미약한 문제점이 있었다.The sound absorption pipe 4a structure of the conventional extension pipe 4 is designed to suppress and reduce the noise generated when the flow path is formed, but there is a weak noise reduction effect.

본 고안은 연장관에서 발생하는 소음을 원주상에서 위상제어하고 원주방향의 압력변동을 순환시킴을 목적으로 한 것이다.The present invention aims to phase out the noise generated by the extension pipe on the circumference and to circulate the pressure fluctuations in the circumferential direction.

상기 목적을 달성하기 위한 본 고안은 링 또는 실린더형상의 입구를 갖는 사이드 브런치 공명기로 구성된 위상 제어수단과, 유체가 빠져나가는 부분에 흡음재를 배치하여 원주방향의 압력맥동을 저감시키는 압력 맥동 저감수단을 갖는 흡음파이프를 제공하여 소음을 낮춘 것이다. 본 고안의 구성은 다음과 같다.The present invention for achieving the above object is a phase control means composed of a side brunch resonator having a ring or cylindrical inlet, and a pressure pulsation reducing means for reducing the pressure pulsation in the circumferential direction by arranging a sound absorbing material in the portion through which the fluid exits; It is to provide a sound absorbing pipe having a low noise. The configuration of the present invention is as follows.

노즐(5)과 유연 연장관(2)사이에 위치하여 유로를 형성하는 본 고안은 연장관은 제4도에서 본인 바와같은 흡음파이프(4b)로 제작된다.The present invention, which forms a flow path between the nozzle 5 and the flexible extension tube 2, is made of a sound absorbing pipe 4b as shown in FIG.

상기 흡음파이프(4b)는 유로방향에 대하여 끝쪽에 여러면상에서 위상 제어가 가능한 위상제어수단과, 이 위상 제어수단 뒷쪽에 원주방향의 압력변동을 순환시키는 압력저감 수단을 구성한다.The sound-absorbing pipe 4b constitutes phase control means capable of phase control on multiple surfaces at the end with respect to the flow path direction, and pressure reduction means for circulating pressure fluctuations in the circumferential direction behind the phase control means.

위상제어수단은 파이프(12)의 외곽쪽으로 둥글게 관의 직경을 확장시켜 공간을 형성한 공명통(13)과, 이 공명통(13)과 파이프(12) 내경을 지나는 유로가 통할 수 있는 입구인 실린더 형상의 입구(14)로 구성된다.The phase control means has a cylinder shape which is an inlet through which a resonant cylinder 13, which extends the diameter of the tube to the outer side of the pipe 12, forms a space, and an passage through which the resonant cylinder 13 and the inner diameter of the pipe 12 pass. Consists of an inlet 14.

압력 맥동 저감수단은 제5도에서 보인 바와같이 연장관보스(8)의 내경 벽면에 순음화와 원주방향의 압력맥동을 순화시키는 다수의 돌기(15)가 부착된 흡음재(16)를 설치하여 흡음파이프(4b)로 구성한 것이다.The pressure pulsation reducing means is provided with a sound absorbing pipe 16 provided with a plurality of projections 15 having a plurality of protrusions 15 for purifying pure negative and circumferential pressure pulsations on the inner diameter wall of the extension tube boss 8 as shown in FIG. It consists of (4b).

본 고안의 작용효과는 다음과 같다.Effects of the present invention are as follows.

본 고안의 흡음파이프(4b)는 제4도에서와 같이 파이프(12)의 외곽쪽으로 공명통(13)을 형성하고 유체 이동방향"F"에 포함된 소음이 공명통(13)과 교통할 수 있는 실린더 형상의 입구(14)를 갖는 위상제어수단을 구성하고 돌기(15)를 부착한 흡음재(16)로 압력저감수단을 구성하여 소음을 공명시켜 소거하고 이 소거된 소음과 압력맥동을 저감시키는 것이다.The sound absorbing pipe 4b of the present invention forms a resonance cylinder 13 on the outer side of the pipe 12 as shown in FIG. 4 and the cylinder in which the noise contained in the fluid movement direction "F" can communicate with the resonance cylinder 13. It constitutes a phase control means having an inlet 14 of the shape, and the pressure reducing means is composed of the sound absorbing material 16 to which the protrusions 15 are attached to resonate and eliminate the noise, thereby reducing the noise and the pressure pulsation.

즉, 모터가 회전하여 흡입력이 생성되고 흡입구인 노즐(5)로 부터 압력맥동파가 들어오게 되면 먼저 실린더 형상의 입구(14)부를 통해 소음이 어느 일부분에서 부분적으로 공명되지 않고 유체가 흐르는 모든 원주점에서 위상제어가 이루어지므로 소음제어 효과가 좋다.That is, when the motor rotates to generate the suction force and the pressure pulsation wave enters from the nozzle 5 which is the suction port, first, all the circles through which the fluid flows without the noise partially resonating in a portion through the cylindrical inlet 14 part. Phase control is performed at main bar, so noise control effect is good

이는 종래 공명구조가 유체 흐름 방향에 대하여 무방향성과 점공명 소스를 가진 공명입구로 인해 소음 저감 효율이 좋지 못한 현상을 개선한다.This improves the phenomenon in which the conventional resonance structure is not good in noise reduction efficiency due to the resonance inlet having non-directionality and point resonance source with respect to the fluid flow direction.

연장관인 흡음파이프 길이는 소음저감 효율과 상호관계에 존재하는데 그 길이를 모터의 회전 성분이나 팬날개 소음성분의 주파수 파장의 1/n(n : 정수)이 되도록 하는 것이 바람직하다.The length of the sound absorbing pipe, which is an extension tube, is correlated with the noise reduction efficiency, and the length of the sound absorbing pipe is preferably 1 / n (n: integer) of the frequency wavelength of the rotational component of the motor or the noise component of the fan blade.

노즐(5)을 통해 유입된 유체맥동성분은 먼저 전술한 바와같은 위상제어 수단을 갖는 공명 구조에 의해 제어 또는 제거되고 그 성분들은 돌기(15)가 있는 흡음재(16)를 통과하면서 평활화되어 압력맥동의 제거를 순환시키는데 이 돌기(15) 는 원주방향의 압력맥동성분의 유체흐름을 제어하는 역활도 병행한다.The fluid pulsation component introduced through the nozzle 5 is first controlled or eliminated by the resonance structure having the phase control means as described above, and the components are smoothed while passing through the sound absorbing material 16 having the protrusion 15 and pressure pulsation. This projection 15 also serves to control the fluid flow of the pressure pulsating component in the circumferential direction.

이와같은 본 고안의 흡음파이프는 유체가 흐르는 모든 원주점에서 위상제어가 가능한 실린더 형상의 입구부를 갖는 위상제어수단과, 소음의 순화 및 원주방향의 압력 변동을 순화시키는 압력저감수단을 구비하여 소음제어와 소음저감효과를 향상시킬 수 있는 것이다.The sound absorption pipe of the present invention has a phase control means having a cylindrical inlet portion capable of phase control at all circumferences of fluid flow, and a pressure control means for purifying the noise and for reducing the pressure fluctuations in the circumferential direction. And noise reduction effect can be improved.
