Vacuum cleaner and method for reducing noise generated thereby

摘要

A vacuum cleaner has a discharge flow path (16) and a discharged-air filter (18) optimally positioned to reduce noise. The vacuum cleaner includes a body (10), a dust collection unit (20) positioned in the body (10) to filter foreign matter, a blower fan unit (30) including a blower fan (31) and a motor (32) to generate suction force, an air vent through which air drawn into the body (10) is discharged, and a discharge flow path to guide the air discharged through a discharge port (42) of the blower fan unit to the air vent (15). The discharge flow path (16) comprises a space defined between the dust collection unit (20) and the blower fan unit (30).
