A dust separation section is provided at a suction air passage between a suction opening of a vacuum cleaner main body and an intake opening of a motor fan to separate dust sucked from the suction opening with air and a dust collection section provided at the suction air passage for collecting the dust separated from the air from the dust separation section. Moreover, the dust separation section of the electric vacuum cleaner has a dust guiding space adapted to inflow the dust sucked from the suction opening from one end of the dust guiding space and for guiding the dust from an other end of the dust guiding space to the dust collection section, through a dust strike section, by an inertia force, and an air guiding air passage is provided to guide air from a midstream of the dust guiding space to the intake opening of the motor fan without passing through the dust collection section.

Electric vacuum cleaner provided with a dust separation section for separating sucked dust and dust collecting section for collecting the dust

There is disclosed a vacuum cleaner including a dust separation section which separates air and dust flowing toward an intake port of a motor blower through a connection port of a cleaner main body. The dust separation section includes an air path forming member which performs a separation function. The forming member includes an introductory port, a derivative port, and an opening disposed between these. In the separation function, while dust-containing air flows toward the derivative port from the introductory port, a part of the air is sucked by the motor blower through the opening. Accordingly, the air is separated from the dust which goes straight in the air path forming member with inertia.
