Abstract

See full text

A cyclonic vacuum cleaner with simple structure, low airflow leakage, excellent maintainability, and less possibility of littering a floor in the case of dumping dusts or care of the cleaner. A cyclonic portion 14 of an approximately cylindrical shape, having a bottom, an introducing portion 15 for introducing dust-laden airflow to the cyclonic portion 14, and a reinforcing rib 35 provided on a lowermost end of the dust-collecting portion 11 for allowing it to stand on end, are formed into a one-piece structure. Thus, the structure from the introducing portion 15 to the cyclonic portion 14 can be simplified and the possibility of airflow leakage can be reduced. Also, maintenance of the cyclonic portion 14 and the introducing portion 15 can be easily performed through the detachment of the dust-collecting portion 11 together with the introducing portion 15. Further, a floor is less likely to be littered with dusts collected within the cyclonic portion 14 by allowing the dust-collecting portion 11 to stand on end with the help of the reinforcing rib 35.
