    • A dust separation section 60 is provided at a suction air passage leading from a suction opening (connection opening 43 or suction opening 52, suction opening 100) of a vacuum cleaner main body 20 to an intake opening (33A, 107A) of a motor fan (33, 107) to separate a dust sucked from the suction opening (connection opening 43 or suction opening 52, suction opening 100) with an air and a dust collection section (dust collection room section 55, dust collection room 104) provided at the suction air passage for collecting the dust separated from the air from the dust separation section 60. Moreover, the dust separation section 60 of this electric vacuum cleaner has a dust guiding space adapted to inflow the dust sucked from the suction opening (connection opening 43 or suction opening 52, suction opening 100) from an one end and for guiding the dust that flows in from an other end to the dust collection section by an inertia force, and an air guiding air passage is provided to be communicated with a midstream of the dust guiding space and is communicated with the intake opening (64, 102H) of the motor fan (33, 107) without passing through the dust collection section.
    • 在从真空吸尘器主体20的吸入口(连接开口43或吸入口52,吸入口100)通向吸入口(33A,107A)的吸入空气通路上设置有灰尘分离部60, 电动机风扇(33,107),用于将从吸入口(连接开口43或吸入口52,吸入口100)吸入的灰尘与空气和集尘部(集尘室部55,集尘室104)分离 在吸入空气通道处,用于收集从灰尘分离部分60分离的空气的灰尘。此外,该电动吸尘器的灰尘分离部分60具有灰尘引导空间,其适于使从吸入口(连接开口 43或吸入口52,吸入口100),并且通过惯性力将从另一端流入的灰尘引导到集尘部,并且将引导空气通道设置于b e与尘埃引导空间的中游连通,并且与电动机风扇(33,107)的进气口(64,102H)连通而不通过集尘部。
