| 20090089959 | Upright vacuum cleaner having suction path diverting valve - An upright vacuum cleaner is provided that includes a cleaner body having a suction motor, a dust-collecting unit, and a body frame where the suction motor and the dust-collecting unit are disposed, a suction inlet body which is hinged to a lower end of the body frame, a hose which has one side fluidly communicating with the body frame and the other side fluidly communicating with an extension pipe through a manipulation handle, and a suction path diverting valve which is disposed on the body frame and has a valve member elastically arranged on a suction path. As the extension pipe is inserted into or withdrawn from a socket on the body frame, the valve member selectively diverts the suction path to a first suction path flowing from the suction inlet body to the dust-collecting unit or a second suction path flowing from the extension pipe to the dust-collecting unit. | 04-09-2009 |
| 20090089960 | Upright vacuum cleaner having suction path switching valve - An upright vacuum cleaner having a suction path switching unit is provided that includes a cleaner body having and a body frame; a suction inlet body hinged to the body frame; a hose in fluid communication with the body frame and an extension pipe; and a suction path switching unit disposed on the body frame. The suction path has an operating duct elastically arranged on a suction path to be able to slide up and down. As the extension pipe is inserted into or withdrawn from a socket disposed on the body frame, the operating duct selectively diverts the suction path to a first suction path flowing from the suction inlet body to the dust collecting unit or a second suction path flowing from the extension pipe to the dust collecting unit. | 04-09-2009 |
| 20090089961 | Vacuum cleaner having suction path switching unit - A vacuum cleaner having a suction path switching unit is provided that includes a cleaner body having a body frame; a suction inlet body hinged to the body frame; an extension pipe assembly having a hose and an extension pipe connected in fluid communication with the hose; and a suction path switching unit disposed on the body frame. The suction path switching unit has a switching duct, at least a portion of which is elastically arranged on a suction path to be displaceable on the suction path. As the extension pipe is fixed on or separated from the body frame, the switching duct is selectively displaced to a first position of opening a first suction path flowing from the suction inlet body to the dust collecting unit or a second position of opening a second suction path flowing from the extension pipe to the dust collecting unit. | 04-09-2009 |
| 20090089969 | Upright vacuum cleaner having steering unit - An upright vacuum cleaner having a steering unit is provided. The upright vacuum cleaner includes a cleaner body having a suction motor and a dust separating and collecting unit, a suction port assembly rotatably connected to a lower portion of the cleaner body, a handle mounted to the cleaner body, and a steering unit to elastically support the cleaner body so that the center of gravity of the cleaner body shifts to the direction where the cleaner body is rotated, according to the rotation of the cleaner body to the left or right. | 04-09-2009 |
| 20090241491 | Multi-cyclone dust separator - A multi-cyclone dust separator is provided, including a first cyclone unit that centrifugally separates dust from dust-laden air drawn into the first cyclone unit through a first air inlet, and a second cyclone unit that is formed inside the first cyclone unit, wherein the second cyclone unit includes a second cyclone body that has a second air inlet through which the air, from which the dust is separated by the first cyclone unit, enters the second cyclone body, and a guide unit that enables the air entering the second cyclone unit to be rotated. | 10-01-2009 |
