Definitions

  • the present invention relates to a dust collector of a vacuum cleaner, and more particularly, to a dust collector of a vacuum cleaner according the preamble portion of claim 1 that has an increased dust collection capacity.
  • a vacuum cleaner is a device that can suction air containing dust using the vacuum pressure generated by a vacuum motor mounted in a main body and filter off the dust in the main body.
  • Such a vacuum cleaner includes a suction nozzle for suctioning air containing dust, a main body of the vacuum cleaner that communicates with the suction nozzle, an extension tube for guiding the air suctioned through the suction nozzle to the main body, and a connecting passage for connecting the air that passes through the extension tube to the main body.
  • the suction nozzle forms a nozzle suction opening of a predetermined size on a bottom thereof, for suctioning air containing dust collected on the floor.
  • a drive unit that generates suctioning force to suction outside air including dust through the suctioning nozzle.
  • a dust collector for separating and storing dust is detachably installed in the main body.
  • the dust collector separates and stores dust in air that is suctioned through the suction nozzle.
  • the dust collector includes a dust collection body, an inlet through which air is suctioned into the dust collection body, a cyclone unit separating dust from air suctioned into the dust collection body, a dust storage part storing the dust separated in the cyclone unit, and an outlet through which the purified air is discharged.
  • the dust stored at the bottom of the dust collection body (that is, the dust in the dust storage part) is continuously circulated along an inner circumference of the dust collection body by means of a circulating current within the dust collection body while the vacuum cleaner is operating.
  • the dust settles down on the floor of the dust collection body and is stored therein at a low density.
  • the dust collector of a related art when more than a predetermined amount of dust are stored in the dust collector while the vacuum cleaner is operating, the dust circulates and rises along an inner wall of the dust collector to invade the cyclone unit formed in an upper space of the dust collection body. Thus, the non-separated dust is discharged together with the air current through the outlet, thus lowering the dust collecting effectiveness of the dust collector.
  • the dust settles down on the bottom of the dust collection body and has a low density.
  • the dust inside the dust collection body takes up excessive volume in proportion to its weight, necessitating frequent (and therefore, cumbersome) emptying of the dust collection body in order to maintain a level of dust collecting effectiveness.
  • JP 58-175532 which has been used to form the preamble portion of claim 1, discloses a dust collector for a vacuum cleaner which has a fixed first plate provided in a dust container and a second plate supported in the dust container so as to be pivotable bi-directionally from one side of the fixed plate to the opposite side of the fixed plate, thereby compressing dust collected in the dust container between the plates.
  • the second plate is manually operable by means of a crank handle removably insertable from the outside of the vacuum cleaner into a receptacle of the axis of the second plate of the dust collector placed inside the vacuum cleaner.
  • the present invention is directed to a dust collector of a vacuum cleaner that substantially obviates one or more problems due to limitations and disadvantages of the related art.
