Airflow system for bagless vacuum cleaner

摘要

A bagless vacuum cleaner ( 10 ) includes a nozzle assembly ( 16 ) having a suction nozzle for picking up dirt and debris from a surface to be cleaned and a canister assembly ( 18 ) including a cavity ( 32 ). A dust collection assembly ( 12 ) is received and held in that cavity ( 32 ). The dust collection assembly ( 12 ) includes a filtering subassembly ( 100 ) and a dust container ( 102 ). The dust container ( 102 ) has an open top ( 104 ), a bottom wall ( 106 ), a first cylindrical sidewall ( 108 ), an inlet ( 110 ), and a downwardly directed outlet ( 112 ) extending through the bottom wall. An airstream conduit is provided for conveying a vacuum airstream between the suction nozzle and the inlet. A suction fan ( 34 ) and suction fan drive motor ( 35 ) carried on either the nozzle assembly ( 16 ) or the canister assembly ( 18 ) generates the vacuum airstream for drawing dirt and debris through the suction nozzle, the airstream conduit and the dust container ( 102 ).
