Abstract
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.
