Abstract

본 발명은 진공청소기의 흡음방 구조에 관한 것으로, 보다 상세하게는 흡음방의 내부에 장착된 모터에서 배출되는 고주파소음이 본체부의 상부측으로 전달되는 것을 효과적으로 차단함으로서 보다 정숙한 소제 작업을 이룰수 있는 고주파소음을 막은 흡음재를 부착한 흡음방구조제 관한 것이다.The present invention relates to a sound-absorbing room structure of a vacuum cleaner, and more particularly, to high-frequency noise that can achieve more quiet cleaning work by effectively preventing the high-frequency noise emitted from the motor mounted inside the sound-absorbing room to be transmitted to the upper side of the main body. It is related with the sound absorption structure which attached the sound absorption material.

본 발명은 진공청소기의 내부에 장착되는, 모터를 내장하는 중공형의 케이스를 갖추어 상기 모터에서 발생되는 소음이 외부로 유출되는 것을 차단하기 위한 흡음방구조에 있어서, 상기 케이스의 외주면 상부측에는 모터에서 발생되는 상부측으로 누출되는 소음을 차단하기 위한 흡음재가 부착됨을 특징으로 하는 고주파소음을 막는 흡음재를 부착한 흡음방구조를 제공한다.The present invention provides a sound absorbing structure for preventing a noise generated by the motor from leaking to the outside by having a hollow case having a built-in motor, which is mounted inside the vacuum cleaner. It provides a sound absorbing structure with a sound absorbing material to prevent high frequency noise, characterized in that the sound absorbing material is attached to block the noise leaking to the upper side generated.

본 발명의 고주파소음을 막는 흡음재릍 부착한 흡음방구조에 의하면 본체부의 상부측으로 모터의 고주파소음을 차단하기 때문에 사용자가 정숙한 느낌으로 청소작업을 수행할 수 있음으로서 완제품의 품질향상을 이룰 수 있는 유용한 효과를 얻는 것이다.According to the sound-absorbing room structure attached to the sound absorbing material to prevent high frequency noise of the present invention, since the high frequency noise of the motor is blocked to the upper side of the main body, the user can perform the cleaning work with a quiet feeling, thereby achieving the quality of the finished product. To get a useful effect.
