초록 ▼

A vacuum cleaner includes a housing and a nozzle in fluid communication with the housing. A suction source is held by the housing. The nozzle is in fluid communication with the suction source. A dust cup is selectively secured to the housing. The dust cup includes an inlet in fluid communication with the nozzle and a first inertial dust separation stage positioned downstream from the inlet. A first dust containing chamber is located adjacent the first inertial dust separation stage for holding the dust separated by the first inertial dust separation stage. A second inertial dust separation stage is located downstream from the first inertial dust separation stage. A second dust containing chamber is located adjacent the second inertial dust separation stage for holding dust separated by the second inertial dust separation stage. An outlet is located downstream from the second inertial dust separation stage. The dust cup can be selectively removed from the housing for emptying.

대표청구항 ▼

1. A vacuum cleaner comprising:a housing, a nozzle in fluid communication with said housing; a suction source held by said housing, said nozzle being in fluid communication with said suction source; and a dust separation system communicating with said housing, said dust separation system comprising: an inlet in fluid communication with said nozzle, a first inertial dust separation stage positioned downstream from said inlet, wherein said first stage causes a sudden change in a direction of air flow to separate dust from an air stream flowing through said first separation stage, a second inertial dust separation stage located downstream from said first inertial dust separation stage, a dust containing chamber located adjacent said first and second inertial dust separation stages for holding the dust separated by at least one of said first and second inertial dust separation stages, wherein said dust containing chamber comprises a dust cup and further comprising a lid which is selectively positioned on said dust cup, and an outlet located downstream from said second inertial dust separation stage.
