A vacuum cleaner includes a dust chamber, a dust bag provided in the dust chamber, and an electric blower for generating suction air flow for drawing and collecting dust and dirt in the dust bag. A deodorant is supplied into the dust bag by the suction air flow and directly attached to the dust and dirt. The deodorant has a granule or powder shape.

Vacuum cleaner and dust bag for vacuum cleaner

A vacuum cleaner includes a first dirt separation unit and a second dirt separation unit. The first dirt separation unit has a first inlet port through which a suction air stream including dirt particles is introduced thereinto, and the second dirt separation unit has a second inlet port through which the air stream introduced into the first dirt separation unit is introduced into the second dirt separation. The first and the second inlet port are disposed such that they are not registered with each other. Accordingly, the dirt particles suctioned are separated in two stages, thereby decreasing the possibility of occlusion of a filter and rapid deterioration of a suction force.

Vacuum cleaner

A floor nozzle for a vacuum cleaner of the present invention has an auxiliary agitator provided outside the lateral wall of a main body of the nozzle. The auxiliary agitator is covered by a protecting cover, so as to ensure safety during use. Moreover, a stirring member, a dust outlet and confirmation holes allow dust to be discharged out of the main body more easily and smoothly, while preventing burning or breaking of the agitator.

Vacuum cleaner floor nozzle having an auxiliary agitator

A vacuum cleaner introduces dust, as well as air, from a nozzle connected with the distal end of a hose into a dust collecting section in the cleaner body through an intake section, while detecting, by means of a detector, the volume of dust being introduced, and controls the output of an electric blower in accordance with the detected volume. One end of the intake section is connected with the proximal end of the hose, while the other end projects into the dust collecting section. Light-emitting and light-receiving elements are provided in the intake section to constitute the detector so as to enable positive detection of dust, easy checking of the contamination of the detector, and easy wiping of the detector.
