Abstract

본 발명은 진공청소기의 소음제거구조에 관한 것으로, 소리를 흡수하는 흡차음재와 소리에너지의 진행을 차단 하면서 소리가 갖는 위상차에 의하여 소리를 상쇄하는 다공벽재와, 소리가 차단되면서 반사되는 차단제를 결합한 구조의 내벽재를 흡기모터 주변에 형성된 확장공간 및 여기에 연결된 배기경로의 내벽에 구성함으로써 소리가 흡수, 공명, 반사되는 과정을 반복시켜 진공청소기의 모터구동에 의하여 발생되는 소음 및 흡기된 상태의 기류가 배기되는 과정에서 발생되는 완류소음등이 격감되는 진공청소기를 제공하게 한다.The present invention relates to a noise canceling structure of a vacuum cleaner, comprising: a sound absorbing and insulating material absorbing sound and a porous wall material canceling sound by phase difference of sound while blocking the progress of sound energy; By constructing the inner wall material of the structure in the expansion space formed around the intake motor and the inner wall of the exhaust path connected to it, the sound absorption, resonance, and reflection are repeated so that the noise generated by the motor driving of the vacuum cleaner and It is possible to provide a vacuum cleaner in which slow noise generated in the process of air flow is reduced.
