Patent number: 7731769Abstract: Provided is a cyclonic dust collection unit for conveniently removing a foreign object filtered therein. The cyclonic dust collection unit includes: a first filtering chamber for filtering a first foreign object having a first size using a cyclone airflow; a second filtering chamber for filtering a second foreign object having a second size smaller than the first size of the first foreign object, the second foreign object being contained in the air passed through the first filtering chamber; a foreign object storing chamber for storing the first and/or second foreign object(s) separated through the first and second filtering chambers; a filter disposed in the first filtering chamber, for separating the first foreign object on an outer surface thereof; and a cutaway hole formed in a longitudinal direction thereof.Type: GrantFiled: September 23, 2005Date of Patent: June 8, 2010Assignee: LG Electronics Inc.Inventor: Young Gun Min

Patent number: 7640623Abstract: A vacuum cleaner is provided. The vacuum cleaner includes suction means that provides suction force, a suction nozzle that uses the suction force provided by the suction means to draw in particle laden air, a dust collecting box that receives the particle laden air drawn in through the suction nozzle, an upper cover having an opening at a central portion thereof that provides for selective opening/closing of an upper portion of the dust collecting box, and a filter assembly that is selectively fastened to an edge of the opening, for filtering dust from the particle laden air and discharging the air upward. This structure simplifies cleaning and replacement of the dust collector assembly.Type: GrantFiled: September 20, 2004Date of Patent: January 5, 2010Assignee: LG Electronics Inc.Inventors: Jae Duck Jung, Il Gyeong Go, Young Gun Min, Hyung Il Kim
