A vacuum cleaner is provided. The vacuum cleaner includes a main body, a suction nozzle coupled to the main body to draw in particle laden air, and a dust collecting assembly detachably coupled to the main body and including a dust collecting container that has a dust collecting space formed therein. Particle laden air is drawn in through a polluted air inlet, and particle free air is discharged through a clean air outlet of the dust collecting container. The main body includes a dust collecting assembly receiving groove that receives the dust collecting assembly, and a clean air inlet is provided on an inner wall of the dust collecting assembly receiving groove, facing the dust collecting assembly. The clean air inlet is in communication with an outlet of the dust collecting assembly through which particle free air is discharged from the dust collecting assembly.

Dust collector of vacuum cleaner

Disclosed is a vacuum cleaner including a head having an inlet for sucking in air containing impurities from outside; a dust collector including: a dust collecting container having a handle on a side thereof, and sucking in polluted air and collecting impurities separated from the polluted air, and having an opened top surface for discharging air separated from the impurities; and a top lid including a fixing groove and a guiding member, and detachably provided at the dust collecting container for closing the opened top of the dust collecting container, wherein the guiding member is coupled to a predetermined part of the dust collecting container such that the fixing groove is positioned at a predetermined location when the top lid is assembled with the dust collecting container; a main body having a dust collector receiving recess in front part thereof, wherein the dust collector is detachably provided; and a fixing device provided at an upper front portion above the dust collector receiving recess, and having a protrusion caught by the fixing groove of the top lid, the fixing device fixing the dust collector on the main body, and releasing the dust collector when the dust collector is separated from the main body.

Vacuum cleaner

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.

Disclosed is a vacuum cleaner including a head having an inlet for sucking in polluted air with impurities from outside by an operation of an air suction device generating air suction force; a dust collector for collecting impurities contained in the polluted air; a main body having a dust collector receiving recess to which the dust collector is detachably provided; and a fixing device fixing the dust collector on the main body and releasing the dust collector when the dust collector is separated, wherein the fixing device including a switch provided at the main body and controlling the fixing state of the dust collector; and an elastic member incorporated integrally into the switch and restoring the switch to a fixing location of the dust collector.

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.
