Vacuum cleaner and method for reducing noise generated thereby
Abstract:
A vacuum cleaner has a discharge flow path and a discharged-air filter optimally positioned to reduce noise. The vacuum cleaner includes a body, a dust collection unit positioned in the body to filter foreign matter, a blower fan unit including a blower fan and a motor to generate suction force, an air vent through which air drawn into the body is discharged, and a discharge flow path to guide the air discharged through a discharge port of the blower fan unit to the air vent. The discharge flow path comprises a space defined between the dust collection unit and the blower fan unit.
