Intake air outlets 15 for flushing through the floor surface 11 are provided in several places. And as can be seen from the longitudinal cross-sectional view of the center part of the floor suction port of FIG. 4, the tip of the intake-out port 15 of the partition 10 is provided with the taper of the floor surface-flushing direction.

도 5는 터빈부의 종단면도이고, 상부케이스(1)에 개구된 흡기구(12)로부터 흡입된 흡기는 공기류(16)가 되어 터빈(9)을 회전한 다음, 터빈실을 포함하는 유로(11)로 토출되는 모양을 나타내고 있다.5 is a longitudinal cross-sectional view of the turbine portion, and the intake air suctioned from the intake port 12 opened in the upper case 1 becomes the air flow 16 to rotate the turbine 9, and then the flow path 11 including the turbine chamber. ) Is discharged.

이 구성에서, 전기청소기를 운전하여 청소를 하면 흡기구(12)로부터 터빈(9)에 공기가 흘러 터빈을 회전시킨다. 이 회전력에 동기(同期)하여 회전브러시(7)가 회전하고, 그 회전브러시(7)의 블레이드(13)로 피(被)청소면을 쓸어모아, 회전브러시(7)의 후방에 있는 안내유로(14)로부터의 흡입기류를 타고 자연스럽게 연결호스(4)를 통과하여 청소기 본체로 흡입된다.In this configuration, when the vacuum cleaner is operated and cleaned, air flows from the intake port 12 to the turbine 9 to rotate the turbine. In synchronization with this rotational force, the rotary brush 7 rotates, sweeps the cleaning surface with the blade 13 of the rotary brush 7, and guides the flow path behind the rotary brush 7 ( The intake air flow from 14 is naturally sucked into the cleaner body through the connection hose (4).
