A dust-collecting device includes a cylindrical casing and an insertion part. The casing includes an introduction port introducing dust-containing air. The insertion part is positioned inside the casing to allow a swirling flow of the dust-containing air to be formed between the insertion part and the casing. The insertion part includes a cylindrical side surface part spaced away from and facing the casing and a projection part. The projection part includes, in a side of the first dust-collecting part, a projection surface projecting outward from the side surface part. The projection surface includes plural straightening parts and a connection part. The straightening parts are formed spirally toward the side of the first dust-collecting part, from upstream to downstream sides of the swirling flow. The connection part connects a downstream end side of one of the straightening parts and an upstream end side of another one of the straightening parts.

Dust-collecting device and vacuum cleaner

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.

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.
