본 고안은 진공청소기의 흡음장치에 관한 것으로, 특히 진공청소기의 청소시, 흡입에 의하여 발생되는 모터의 구동소음과 배기소음을 최대한으로 흡음 할수 있도록 한 진공청소기의 흡음장치에 관한 것이다.The present invention relates to a sound absorber of a vacuum cleaner, and more particularly, to a sound absorber of a vacuum cleaner capable of absorbing maximum driving noise and exhaust noise of a motor generated by suction when cleaning a vacuum cleaner.
종래의 진공청소기는 제1도에 도시한 바와같이, 몸체(1)의 후방에 장착된 모터(2)의 흡입력으로 브러쉬(3)를 통해서 실내의 먼지나 이물질을 집진실(4)로 흡입하고, 흡입된 공기는 모터(2)의 후방에 위치한 소음실(5)을 통해 배기구(6)로 배출하면서 실내청소를 하도록 되어있는바. 상기와 같은 구동하는 진공청소기의 경우, 청소시에 모터의 구동 소음뿐만 아니라 배기소음이 상당히 심하게 발생되어 실내환경을 어지럽히게 되는 문제점이 있어, 상기 모터(2)의 후방에 청소시 발생되는 모터소음과 배기소음을 줄이기 위하여 소음실(5)이 구비하고 이 소음실(5)의 내측격벽 상하부 및 상기 배기구(6)의 격벽에 흡음재(7)을 취부하여, 청소시 상기 모터(2)에서 상,하 방향으로 발생되는 소음과, 배기구(6)로 배출되는 배기소음을 흡음하도록 하였다.As shown in FIG. 1, a conventional vacuum cleaner sucks dust or foreign matter into the dust collecting chamber 4 through the brush 3 by the suction force of the motor 2 mounted to the rear of the body 1, and In addition, the sucked air is to be cleaned indoors while exhausting through the noise chamber (5) located in the rear of the motor (2) to the exhaust port (6). In the case of the driving vacuum cleaner as described above, there is a problem that not only the driving noise of the motor at the time of cleaning but also the exhaust noise is generated so much that it disturbs the indoor environment, and the motor noise generated at the rear of the motor 2 is cleaned. The noise chamber 5 is provided to reduce the exhaust noise and the sound absorbing material 7 is attached to the upper and lower portions of the inner partition wall of the noise chamber 5 and the partition wall of the exhaust port 6, and the upper surface of the motor 2 is cleaned during cleaning. The sound generated in the downward direction and the exhaust noise discharged to the exhaust port 6 are absorbed.
그러나 상기 소음실(5)의 격벽에 취부된 흡음재(7)는 상기 청소시에 발생되는 구동소음 및 배기소음중 비교적 높은 고주파대의 소음은 어느정도 흡음을 하여 감소를 할수 있으나, 500HZ 이하의 저주파대의 소음은 흡음을 하지 못하게 되어 소음 억제에 그다지 효과적이 못한 문제점을 가지고 있었다.However, the sound absorbing material 7 mounted on the partition wall of the noise chamber 5 may reduce the noise of a relatively high frequency band among the driving noise and the exhaust noise generated during the cleaning by absorbing it to some extent, but the noise of the low frequency band of 500HZ or less. Was unable to absorb sound, which was not very effective in suppressing noise.
따라서 본 고안의 목적은 진공청소기에 있어서, 청소시 발생되는 소음중 저주파대의 소음을 효과적으로 흡음하여 실내환경을 해치지 않은 상태에서 실내 청소를 할 수 있도록 하고자 하는데 있다.Therefore, an object of the present invention is to vacuum the vacuum cleaner, to effectively absorb the low-frequency noise of the noise generated during cleaning to enable the indoor cleaning without harming the indoor environment.
상기의 목적을 실현하기 위하여 본 고안은 진공청소기에 있어서, 모터의 후방에 위치한 소음실에 청소시 발생되는 저주파대 소음을 흡음하는 별도의 흡음수단을 구비하여서 된 것을 특징으로 한다.In order to realize the above object, the present invention is characterized in that the vacuum cleaner is provided with a separate sound absorbing means for absorbing low-frequency noise generated during cleaning in the noise chamber located at the rear of the motor.
이하 첨부된 도면에 의거 본 고안을 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
제2도는 본 고안 진공청소기의 일부절결 측단면도이고, 제3도는 본 고안 진공청소기의 사용시 저주파 소음 측정 그래프이다.FIG. 2 is a partially cutaway side cross-sectional view of the vacuum cleaner of the present invention, and FIG. 3 is a low frequency noise measurement graph when the vacuum cleaner of the present invention is used.
몸체(1)의 후방에 장착된 모터(2)의 흡입력으로 브러쉬(3)를 통해서 실내의 먼지나 이물질을 집진실(4)로 흡입하고, 흡입된 공기는 모터(2)의 후방에 위치한 흡음재(7)가 취부된 소음실(5)을 통해 배기구(6)로 배출하면서 실내청소를 하는 진공청소기에 있어서, 상기 소음실(5)의 상,하격벽과 배기구(6)의 격벽에 취부된 흡음재(7)와 상기 소음실(5)의 상,하 격벽과 배기구(6)의 격벽사이에 흡음수단(8)(9)(10)을 구비하되, 상기 흡음수단(8)(9)(10)에는 저주파음을 흡수하는 공기층(11)을 형성하여서 된 것이다.The suction force of the motor 2 mounted at the rear of the body 1 sucks dust or foreign matter into the dust collecting chamber 4 through the brush 3, and the sucked air is a sound absorbing material located at the rear of the motor 2. In the vacuum cleaner for cleaning the room while discharging to the exhaust port (6) through the noise chamber (5) in which (7) is mounted, the upper and lower partitions of the noise chamber (5) and the partitions of the exhaust port (6) Sound absorbing means (8), (9) and (10) are provided between the sound absorbing material (7) and the upper and lower partitions of the noise chamber (5) and the partitions of the exhaust port (6). 10) is formed by forming an air layer 11 to absorb low frequency sound.
상기와 같이 구성된 본 고안의 작용효과를 설명하면 다음과 같다.Referring to the effect of the present invention configured as described above are as follows.
먼저 청소를 하기 위하여 청소기에 전원을 인하게 되면, 상기 청소기는 본체(1)내부의 모터(2)가 구동하면서 흡입력을 발생하게 된다.First, when the power is supplied to the cleaner for cleaning, the cleaner generates a suction force while the motor 2 inside the main body 1 is driven.
이때 브러쉬(3)를 사용자는 청소를 하고자 하는 곳에 대게 되면, 상기 모터(2)의 흡입력에 의하여 브러쉬(3)주변의 공기와 함께 먼지나 이물질을 본체(1)의 집진실(4)로 흡입하게 되고 이때 흡입된 공기와 모터(2)이 구동소음은 몸체(1)의 후방에 위치한 소음실(5)와 배기구(6)을 통해서 배기되게 되는데, 상기 모터(2)의 소음과 배기되는 소음은 소음실(5)의 격벽에 취부된 다공질의 흡음재(7)에 의하여 1차흡음을 하고, 상기 흡음재(7)와 격벽사이에 공기층(11)이 형성된 흡음수단(8)(9)(10)에 의하여 2차로 흡음을 하게 되므로, 청소시 모터(2)의 구동소음은 배기소음을 줄이면서 청소를 할수 있게 되며, 특히 500HZ 저주파음에 대하여는 제3도의 (B)의 그래프에 나타나는 바와같이, 제3도의 (A)의 그래프 즉 흡음재(7)만을 취부하였을 때 흡음을 할 때 비하여 훨씬 흡음계수가 양호한 것으로 나타난 것으로 보아, 청소시 발생되는 소음을 최대한으로 흡음하면서 청소를 할수 있게 되는 것이다.At this time, when the user touches the brush 3 to be cleaned, the suction force of the motor 2 sucks dust or foreign matter into the dust collecting chamber 4 of the main body 1 together with the air around the brush 3. In this case, the suctioned air and the motor 2 drive noise is exhausted through the noise chamber 5 and the exhaust port 6 located in the rear of the body 1, the noise of the motor (2) and the exhaust noise Sound absorbing means (8) (9) (10) having primary sound absorption by the porous sound absorbing material (7) attached to the partition wall of the noise chamber (5), and the air layer (11) is formed between the sound absorbing material (7) and the partition wall. 2) by the second sound absorption, the cleaning of the driving noise of the motor (2) can be cleaned while reducing the exhaust noise, especially for 500HZ low frequency sound, as shown in the graph of (B) of FIG. The graph in FIG. I've found that appeared to be good, but being able to clean up while absorbing the noise generated during cleaning as much as possible.
이상에서 설명한 바와 같이 본 고안은 진공청소기의 소음실에 흡음재가 취부된 격벽과 흡음재 사이에 공기층을 형성한 흡음수단을 구비하여, 청소시 발생되는 소음을 2중으로 흡음하면서 청소를 할수 있게 됨으로써, 가능한한 실내 환경을 크게 해치지지 않으면서 청소를 할수 있는 효과를 제공하게 되는 것이다.As described above, the present invention includes sound absorbing means having an air layer formed between the sound absorbing material and the partition wall where the sound absorbing material is installed in the vacuum chamber of the vacuum cleaner, so that the cleaning can be performed while absorbing the noise generated during the cleaning in double. It will provide the effect of cleaning without seriously harming the indoor environment.
