There is provided a vacuum cleaner. The vacuum cleaner includes a dust separation part separating dust contained in air; a dust storing part storing dust separated by the dust separation part; a compression unit dividing the dust separation part and dust storing part, for compressing dust stored in the dust storing part; a motor connection passage communicated with a motor generating a negative pressure; a compression passage communicated with the dust storing part; a dust collection passage communicated with the dust separation part; and a flow passage control unit selectively opening and closing the compression passage and the dust collection passage.

Vacuum cleaner

There is provided a vacuum cleaner. The vacuum cleaner includes a dust storing part; a compression passage connecting a motor generating a negative pressure to the dust storing part; a flow passage control unit that controls opening and closing of the compression passage; and a compression unit compressing dust stored in the dust storing part when the compression passage is opened.

There is provided a dust compressing apparatus for a dust collecting unit of a vacuum cleaner. In the dust compressing apparatus, a compartment plate divides an inner space of a dust collection container into an upper foreign substance separating compartment and a lower foreign substance storing compartment, and a branching unit guides airflow. The branching unit includes a motor connection passage directed to a motor generating a negative pressure, a dust collection passage directed to the foreign substance separating compartment, and a compression passage directed to the foreign substance storing compartment. A flow passage control unit controls connections between the passages of the branching unit. A compression unit compresses foreign substances stored in the foreign substance storing compartment by moving the compartment plate to the foreign substance storing compartment using the negative pressure transmitted through the compression passage.
