Abstract

본 발명은 집진실의 내부에 먼지가 가득차서 모터측으로 공기가 공급되지 않은 경우, 모터와 흡음방의 내부에 진공압력이 형성되어 모터와 흡음방이 번형 및 파손되는 것을 방지하도록 개선된 진공 압력 보호장치를 갖춘 청소기의 흡음방에 관한 것이다.The present invention provides a vacuum pressure protection device that is improved to prevent the motor and the sound-absorbing room from being burned and damaged when a vacuum is formed inside the motor and the sound-absorbing room when the dust is filled in the dust chamber and the air is not supplied to the motor side. It relates to the sound absorption room of the equipped vacuum cleaner.

본 발명은 진공청소기의 모터를 내장하고, 상기 모터에 의해 발생하는 소음이 외부로 유출되는 것을 차폐하는 흡음방에 있어서, 모터를 감싸고, 원통형상을 가지며 내부에는 모터와의 사이에 배기유로를 형성하여 모터에서 배출된 배기가 외부로 빠져나가도록 하고 소음을 차폐하도록 된 외부케이싱에는 모터의 내부에 진공압력이 형성되면 외기를 인입시키도록 된 외기 유입 수단이 장착됨을 특징으로 하는 진공 압력 보호장치를 갖춘 청소기의 흡음방을 제공한다.The present invention is a sound absorption room that incorporates a motor of the vacuum cleaner and shields the noise generated by the motor from leaking to the outside, surrounding the motor, having a cylindrical shape and forming an exhaust passage between the motor and the inside. The external casing is configured to allow the exhaust discharged from the motor to escape to the outside and to shield the noise. The vacuum casing is provided with an external air inlet means for introducing external air when a vacuum pressure is formed inside the motor. Provides a sound absorbing room equipped with a vacuum cleaner.
