发明名称 Electric vacuum cleaner
摘要 An electric vacuum cleaner in which it is possible to ensure an increased area of a lower mesh filter 34 while saving space is provided. In a partition wall 26 positioned between a coarse dust air passage 31 through which coarse dust that has been separated in a separating section 16 and passed through an approximately straight cylindrical separating main body part 17 passes with sucked air and a fine dust air passage 32 through which minute dust that has been separated in the separating section 16 and passed through auxiliary openings 18 passes with sucked air, there is formed a communication port 35 for letting the sucked air flowing into the coarse dust air passage 31 outside along the coarse dust air passage 31 in an opening manner, and the communication port 35 is provided with the lower mesh filter 34 , whereby it is possible to ensure an increased area of the lower mesh filter 34 easily while saving space without increasing the cross-sectional area of the coarse dust air passage 31 or the size of a vacuum cleaner main body 2 , etc.
