| 20080229539 | Upright vacuum cleaner using return current of discharging air - An upright vacuum cleaner includes a suction nozzle unit, an inlet formed on a bottom surface of the suction nozzle unit, an injection path disposed near the inlet, a suction motor mounted in the suction nozzle unit, and a main body attached to the suction nozzle unit and in fluid communication with the suction motor. The injection path ejects air toward a surface to be cleaned. The suction motor generates a suction force to draw in air and dust through the inlet. The main body separates dust from the air using centrifugal force, collects the dust, and discharges the air to the suction nozzle unit. The air discharged from the main body flows through the suction motor, is ejected from the injection path toward the surface to be cleaned, and is then suctioned into the inlet so that a portion of the discharged air circulates within the vacuum cleaner. | 09-25-2008 |
| 20090031520 | Upright vacuum cleaner - A vacuum cleaner including a sterilizing unit is provided. The sterilizing unit includes a hot air circulating duct and an air passage switching part. The hot air circulating duct is disposed between a motor chamber and an air inflow part of the dust separating unit to guide air from the motor chamber to the air inflow part of the dust separating unit. The air passage switching part is disposed at a place where the air inflow part, the suction hose and the hot air circulating duct intersect. The air passage switching part is movable between a cleaning position and a sterilizing position to switch a flow of air, the cleaning position being a position that blocks off between the air inflow part and the hot air circulating duct and the sterilizing position being a position that blocks off between the air inflow part and the suction hose. | 02-05-2009 |
| 20090031522 | Suction port assembly of vacuum cleaner - A vacuum cleaner operable on upright mode and canister mode is provided. The vacuum cleaner includes a suction port assembly comprising a suction port and a suction passage to draw in dust-laden air, a cleaner body housing a dust separating unit and a motor connected with the dust separating unit, an operating handle assembly in fluid communication with the cleaner body through a hose and in fluid communication with an extension pipe, and a carrying handle assembly sliding along the cleaner body to increase in length. If the vacuum cleaner is in the upright mode, the extension pipe is in fluid communication with the suction port assembly, is used as a passage for air to pass toward the cleaner body, and supports the cleaner body, while if the vacuum cleaner is in the canister mode, the extension pipe is separated from the cleaner body. | 02-05-2009 |
| 20090044359 | Suction brush having hair removal unit for vacuum cleaner - A suction brush having a hair removal unit for a vacuum cleaner is provided. The suction brush includes a brush body having a rear end fluidly connected to a main body of the vacuum cleaner, a suction port on a lower surface of a front end, and a rotation brush inside the suction port; and a hair removal unit detachably connected to the suction port. | 02-19-2009 |
| 20090044371 | Vacuum cleaner for use in both upright form and canister form - A vacuum cleaner for use in both an upright form and a canister form, which can mount and dismount a cleaner body to and from a suction nozzle assembly is disclosed. The vacuum cleaner includes a suction nozzle assembly to draw in dust or dirt along with air while moving along a surface to be cleaned; a cleaner body having a dust separating unit to separate and collect the dust or dirt from the air drawn in from the surface to be cleaned; a supporting unit hingedly joined to the suction nozzle assembly to support a lower part of the cleaner body to communicate with the suction nozzle assembly; and a locking unit to detachably lock the lower part of the cleaner body to the supporting unit. | 02-19-2009 |
| 20090100635 | Dust collecting unit for vacuum cleaner - A dust-collecting unit for a vacuum cleaner is provided which detachably connected with a cleaner body of the vacuum cleaner. The dust-collecting unit includes a dust receptacle which is disposed under a dust separator disposed in the cleaner body, for collecting dust separated from air by the dust separator and dropping down from the dust separator, a dust receptacle ascending/descending part which is disposed under the dust receptacle and is pivoted in a direction or a reverse direction to ascend or descend the dust receptacle and to press-lock or unlock the dust receptacle to or from the dust separator, and a handle which extends from one side of the dust receptacle ascending/descending part along a lengthwise direction of the dust receptacle and has a gap with respect to a circumferential surface of the dust receptacle. | 04-23-2009 |
| 20090300871 | Cyclone dust-collecting apparatus and vacuum cleaner having the same - A cyclone dust-collecting apparatus and vacuum cleaner having the cyclone dust-collecting apparatus are provided. The cyclone dust-collecting apparatus includes a cyclone unit comprising a primary cyclone unit having a grill filter formed therein, and a secondary cyclone unit fluidly communicating with the primary cyclone unit; a cover unit detachably disposed above the cyclone unit to discharge air discharged from the secondary cyclone unit; and a dust-collecting unit detachably disposed below the cyclone unit to collect dust separated by the primary cyclone unit and secondary cyclone unit, wherein air flows into the grill filter in the same direction as air flows into the primary cyclone unit. | 12-10-2009 |
| 20100251504 | APPARATUS FOR DIVERTING FLUID FLOW PATH - An apparatus for diverting a fluid flow path automatically diverts a fluid flow path in accordance with inclining of a main body, and includes two or more selectable fluid flow paths through which an external air stream is drawn, a fixed fluid flow path to be selectively connected to one of the selectable fluid flow paths, a path selecting unit to connect the fixed fluid flow path to one of the selectable fluid flow paths, and a driving member to provide a driving force for path selecting of the path selecting unit. If mounted in an external apparatus, the driving member causes the path selecting unit to move and connect to the fixed fluid flow path in accordance with inclining of the external apparatus. | 10-07-2010 |
