Abstract (en)

A vacuum cleaner for reducing noise from being transmitted to the exterior. The vacuum cleaner includes a main body (10) forming an outer appearance of the vacuum cleaner and including a blower unit (20) for generating suction force and blowing force and a discharge hole (10a) through which purified air from which foreign matter has been filtered is discharged, a discharge passage (42) for guiding air discharged from the blower unit to the discharge hole (10a), and a spiral shaped intercepting passage (42a) for forming a part of the discharge passage (42) and for preventing noise of the blower unit from being transmitted to the exterior. A guide member (43) forming the intercepting passage (42a) is disposed at the outside of the blower unit and serves as an acoustic absorber so that noise transmission to the exterior is reduced.
