20080289141 | Nozzle assembly of vacuum cleaner - A nozzle assembly of a vacuum cleaner is disclosed. The nozzle assembly includes a nozzle assembly body having an air inlet and an air outlet, a drum brush unit disposed in the nozzle assembly body in the vicinity of the air inlet, and having a drum brush disposed to brush away dirt or dust adhered to a surface to be cleaned while coming in rotation contact therewith, and a movable brush unit disposed in at least one of the front and the rear of the air inlet on an undersurface of the nozzle assembly body to pivot in an opposite direction to a moving direction of the nozzle assembly body thus to change a contacting angle to the surface to be cleaned in the range of a predetermined angle and then to brush away dirt or dust adhered to the surface to be cleaned, in moving of the nozzle assembly body. | 11-27-2008 |
20090049642 | Suction brush for vacuum cleaner - A suction brush for a vacuum cleaner is provided. The suction brush includes an upper casing; a lower casing; an elevating plate installed between the upper casing and the lower casing; a cleaned surface sensing part for sensing; a lever rotatably provided around a rotating shaft that is parallel to the elevating plate; and a solenoid. The solenoid rotates the lever in one direction when the surface to be cleaned is the hard floor and rotates the lever in the other direction when the surface to be cleaned is the carpet. The lower casing contacts the surface to be cleaned as the elevating plate descends, while it comes apart from the surface to be cleaned as the elevating plate ascends. | 02-26-2009 |
20090089967 | Suction nozzle for use in vacuum cleaner - A suction nozzle for use in a vacuum cleaner, which can clean a surface to be cleaned having a corner portion where a horizontal surface and a vertical surface meet, such as a staircase, is disclosed. The suction nozzle includes a nozzle body having an air inlet formed in a bottom surface thereof to draw in air, and a brush unit having a liftable brush liftably and lowerably disposed in the nozzle body in front of the air inlet and coming in surface contact with a surface to be cleaned to brush away dirt or dust therefrom. | 04-09-2009 |
20090100629 | Suction nozzle-hanging apparatus for use in vacuum cleaner - A suction nozzle hanging apparatus for use in a vacuum cleaner that can hang and store a suction nozzle assembly having a suction nozzle on a cleaner body. The suction nozzle hanging apparatus includes a fixing part formed on a suction nozzle assembly, the suction nozzle assembly having a suction nozzle and an extended tube connected to the suction nozzle, and a counter fixing part formed on a cleaner body and joining with the fixing part to support the suction nozzle assembly on the cleaner body, wherein the fixing part is disposed to be rotatable on a longitudinal axis of the joining connector. | 04-23-2009 |
