Patent number: 7810211Abstract: A vacuum cleaner is provided that includes a vacuum cleaner main body having a suction pump, a suction nozzle portion that sucks impurities by a suction force supplied by the suction pump, a suction passage that connects the suction nozzle portion to the suction pump, an agitator installed at the suction passage, and a driving device that makes the agitator perform a linear translation. As the agitator is formed narrow and long, a bottom surface of the suction nozzle portion may maintain a small suction area. Therefore the vacuum cleaner attains a high surface pressure which is an advantage of an ordinary type suction nozzle portion, and a high drag coefficient of impurities which is an advantage of a brush type suction nozzle portion.Type: GrantFiled: July 17, 2007Date of Patent: October 12, 2010Assignee: LG Electronics Inc.Inventors: Chung-ook Chong, Keyong-seon Jeong, Kie-tak Hyun, Seong-koo Cho, Geun-bae Hwang, Kyu-chun Choi, Jin-hyouk Shin, Jong-kyu Jang

Publication number: 20100005617Abstract: The present invention discloses a vacuum cleaner which can improve the cleaning performance by filtering off impurities from the sucked air twice according to a cyclone method, and allow the user to easily discharge the collected impurities. The vacuum cleaner includes a primary cyclone unit (100), a secondary cyclone unit (120), and a passage partition unit (131) formed between the primary cyclone unit and the secondary cyclone unit. The sucked air is primarily filtered in the primary cyclone unit (110), and secondarily filtered in the secondary cyclone unit (120), thereby improving the cleaning performance. In addition, a dust container (140) is detachably coupled to the primary cyclone unit (110) or the secondary cyclone unit (120). Therefore, the user can easily remove the impurities collected in the dust container (140) by separating the dust container (140) from the primary and secondary cyclone units.Type: ApplicationFiled: February 23, 2007Publication date: January 14, 2010Inventors: Kie-Tak Hyun, Kyeong-Seon Jeong, Jong-Kyu Jang, Chung-Ook Chong, Jinhyouk Shin, Geunbae Hwang, Youngsoo Kim
