Vacuum cleaner comprising dirt compressing means

摘要

A vacuum cleaner (100) includes a main body (1) having an electric blower (12) for generating a suction air flow, a dirt collecting case (18) for centrifugally separating and collecting dirt, and a compression assembly for compressing dirt collected in the dirt collecting case (18) to reduce a volume thereof. The dirt collecting case (18) has a separation chamber (24) for centrifugally separating dirt from the dirt containing air and a dirt collecting chamber (29) in communication with the separation chamber (24) for accumulating the dirt separated by the separation chamber (24). The compression assembly has a first air intake member (30) provided in the separation chamber (24) and communicating with the electric blower (12), a second air intake member (33) provided in the dirt collecting chamber (29) and communicating with the electric blower (12), a shielding plate (38) for selectively opening the first and the second air intake member (30,33) and an actuator (39,40) for driving the shielding plate (38).
