| 20080250599 | Dust sensing unit for use in vacuum cleaner - A dust sensing unit for use in a vacuum cleaner, which can detect whether there is dust or dirt on a surface to be cleaned and inform a user of the detected result in cleaning, is disclosed. The dust sensing unit includes a body having an air flowing passage therein to move air laden with dust or dirt drawn in through a suction nozzle, a detecting sensor disposed on the air flowing passage to detect whether the dust or dirt is passing through the air flowing passage, a lamp part to operate according to a signal outputted from the detecting sensor, a rotating part disposed to the body to rotate by air flowing through the air flowing passage, and an electric generator rotated by the rotating part to generate an electric power. | 10-16-2008 |
| 20080250764 | Connecting tube having dust sensing function for use in vacuum cleaner - A connecting tube having a dust sensing function is provided. The connecting tube includes a tube element having a first air flowing passage; a body having a second air flowing passage to communicate with the first air flowing passage; a detecting sensor disposed on the second air flowing passage to detect whether the dust or dirt passes through the second air flowing passage; a lamp part to operate according to a signal outputted from the detecting sensor; a rotating part rotatably disposed on the body; a rotation driving-passage part disposed on the body to draw in an external air into the second air flowing passage and thus to rotate the rotating part; an electric generator connected to the rotating part to generate an electric power; and a muffler part to reduce noises from the rotating part and the flowing air. | 10-16-2008 |
| 20080263813 | Vacuum cleaner for using as both canister form and stick form - A vacuum cleaner for use in either a canister form or a stick form is disclosed. The vacuum cleaner includes a cleaner body, a suction unit having an air suction opening formed in a bottom surface of the cleaner body to drawn in air, a dust collecting unit disposed in the cleaner body to separate dust or dirt from the air and to collect and store the dust or dirt therein, and a mode selecting unit on the cleaner body to select one of a first mode and a second mode. The first mode is a mode where a handle member for moving the cleaner body is connected to the cleaner body and the suction unit and the dust collecting unit are communicated with each other. The second mode is a mode where an external accessory is connected to the cleaner body to communicate with the dust collecting unit. | 10-30-2008 |
| 20080263816 | Vacuum cleaner - A vacuum cleaner includes a cyclone dust separating unit which includes a cyclone part to separate dust from a dust-laden air drawn from a surface being cleaned using a centrifugal force, a dust collecting part comprising a dust chamber to accommodate the dust separated at the cyclone part, and a compressing part to compress the dust accommodated in the dust chamber. The compressing part includes a driving part to rotatably drive a driving axis, and a compressing plate driven in a substantially perpendicular direction with respect to the driving axis according to the rotation of the driving axis, and to compress the dust accommodated in the dust chamber. As a result, a vacuum cleaner is provided, which requires a minimum space for the installation of a compressing part to compress dust inside the dust collecting part, and provides maximum compressing force of the compressing part. | 10-30-2008 |
| 20080264011 | Dust compressing apparatus of vacuum cleaner - A dust compressing apparatus of a vacuum cleaner capable of automatically compressing dust or dirt collected in a dust separating unit is disclosed. The dust compressing apparatus includes a compressing plate to compress the dust or dirt collected in the dust separating unit, a moving unit connected to the compressing plate on one side of the dust separating unit to move the compressing plate, an elastic unit to elastically urge the compressing plate to a compressing position where the compressing plate compresses the dust or dirt, and a driving motor to drive the moving unit thus to move the compressing plate. | 10-30-2008 |
| 20080264015 | Dust compressing apparatus of vacuum cleaner - A dust compressing apparatus of a vacuum cleaner that automatically compresses dust or dirt collected and stored in a dust separating apparatus. The dust compressing apparatus includes a compressing plate to compress dust or dirt collected in the dust separating apparatus, a lifting and lowering unit connected to the compressing plate above the compressing plate to lift and lower the compressing plate, and a driving motor to drive the lifting and lowering unit thus to lift and lower the compressing plate. | 10-30-2008 |
| 20090056060 | Stick type vacuum cleaner - A stick type vacuum cleaner is provided. The stick type vacuum cleaner includes a suction port assembly and a stick unit having a first end is engaged with a first side of the suction port assembly and a second end having a handgrip. The suction port assembly includes a casing part comprising a suction port through which air and dust is drawn from the object being cleaned, a suction force generating unit formed inside the casing part to generate a suction force, a dust separating unit to separate and accommodate dust from the drawn air and dust, and a power supply unit to supply power to the suction force generating unit. The suction force generating unit is disposed between the suction port and the dust separating unit so that the drawn air and dust is passed through the suction force generating unit before being introduced into the dust separating unit. | 03-05-2009 |
| 20090056290 | Cyclone dust-separating apparatus of vacuum cleaner - A cyclone dust-separating apparatus includes a cyclone unit having air inflow and air outflow parts that separate dust or dirt from air, the cyclone unit being installed such that a longitudinal axis thereof is substantially horizontally arranged; a dust bin joined to a bottom end of the cyclone unit that collects the dust or dirt separated by the cyclone unit, the dust bin installed in such a manner that a longitudinal axis thereof is substantially perpendicular to the longitudinal axis of the cyclone unit; a nonporous envelope detachably disposed in the dust bin that stores the dust or dirt collected into the dust bin; and a pressure difference-generating passage to communicate an outlet of the air outflow part and the dust bin with each other so as to allow the nonporous envelope to come in contact with an inner surface of the dust bin by a pressure difference between the dust bin and the air outflow part. | 03-05-2009 |
