The dust-collecting apparatus includes an air inlet through which an external air is drawn in, two cyclone chambers into which the external air drawn in through the air inlet air is drawn in, the two cyclone chamber being disposed in parallel, at least one dust-collecting chamber divided in parallel with respect to the two cyclone chambers, and two air outlets through which the external air from the two cyclone chambers is discharged. The air inlet is formed between the two cyclone chambers at a lower part of a cyclone body and the two air outlets are formed in bottom surfaces of the two cyclone chambers, respectively, so that the external air is drawn in through lower parts of one sides of the two cyclone chambers and then discharged through the bottom surfaces of the two cyclone chambers. | 09-09-2010 |
20100263160 | Suction body providing electric energy and cleaner having the same - A suction body for a cleaner is provided that can generate electric energy by itself using air drawn in by the cleaner. A suction body includes an ultraviolet sterilizer that radiates ultraviolet rays toward a surface to be cleaned and sterilizes the surface to be cleaned, a lighting device that emits light, a displaying device that displays a cleaning state, a fan that rotates by drawn-in air, and a generator that converts rotary energy of the fan into electric energy so as to supply the electric energy to the ultraviolet sterilizer, the lighting device, and the displaying device. | 10-21-2010 |
20100319157 | VACUUM CLEANER WITH DETACHABLE CORD REEL UNIT - A vacuum cleaner having a detachable cord reel unit is provided. The vacuum cleaner includes a main body, a brush assembly connected to the main body and, a cord reel unit attachable to and detachable from a discharging portion of the main body, the cord reel unit comprising a power cord and a cooling fan formed therein, wherein the cooling fan stops driving automatically when the cord reel unit is mounted in the main body, and the cooling fan starts driving automatically to cool the power cord when the cord reel unit is detached from the main body. | 12-23-2010 |
20110010887 | TURBINE BRUSH UNIT AND VACUUM CLEANER HAVING THE SAME - A turbine brush unit and a vacuum cleaner having the same are provided. The turbine brush unit may include a turbine brush case, a brush member mounted in the turbine brush case, and a turbine fan unit having a plurality of wings and rotating the brush member. Each of the plurality of the wings may have a curvature point, a primary collision surface with which a primary inlet wind drawn through the inlet portion of the turbine fan unit collides and a secondary collision surface with which a secondary inlet wind collides. The primary and secondary inlet winds apply a force in the rotation direction of the turbine fan unit. | 01-20-2011 |
20110088203 | AIR FLOW SENSING UNIT AND CLEANING APPARATUS HAVING THE SAME - An air flow sensing unit, which may sense an amount of air flowing or an pressure for air flown into the cleaning apparatus by a suction motor or an impeller and inform a user of a time for emptying a dirt collecting receptacle of dust or dirt and/or a time for cleaning or replacing a filter with a new one, and a cleaning apparatus having the same are provided. The unit may include an air flow pipe to fluidly communicate an air flow passage of a cleaning apparatus with the outside, and an indicator positioned in the air flow pipe to be lifted based on a change in amount of air flowing or air pressure generated by air movement in the air flow passage and to be lowered due to a weight thereof. | 04-21-2011 |
