Electric vacuum cleaner
First Claim
1. An electric vacuum cleaner having a cyclonic separation cylinder for flowing into dusts containing air sucked from a suction port and for removing the dusts according to a centrifugal separation and a dust collecting case having an opening which communicates with said cyclonic separation cylinder, whereina center axial direction of said cyclonic separation cylinder is arranged at a substantial vertical direction,an inflow inlet to said cyclonic separation cylinder has a position where air flows into a substantial tangential direction and is provided at a lower portion of said cyclonic separation cylinder, andsaid opening of said dust collecting case is provided at an upper portion of said cyclonic separation cylinder.

Abstract
An object of the present invention is to provide an electric vacuum cleaner equipped with a compact and easy-to-operate cyclonic separation type dust collector.
To accomplish the object, the present invention mounts a cyclonic separation cylinder (104) that centrifugally separates and captures dust and a dust collecting case (105) that contains a first auxiliary filter (106) detachably on the lower case (101) of the cleaner body (1) and part of air from the cyclonic separation cylinder (104) is fed to the motor-driven blower through the dust collecting case (105).
