Abstract: A dust separating apparatus for a vacuum cleaner is provided. The dust separating apparatus includes a cyclone configured to provide a plurality of cyclone airflows therein and a dust container provided separate from the cyclone. The cyclone includes a first air inlet configured to receive an airflow containing dust and a dust outlet configured to discharge dust separated by the plurality of cyclone airflows. The dust outlet is located in a central portion of the cyclone. The dust container is removably placeable into communication with the dust outlet to collect dust separated in the cyclone. A vacuum cleaner including the dust separating apparatus is also provided.

Abstract: The present invention discloses a vacuum cleaner including a main body (1) of the vacuum cleaner, a wheel (2) rotatably mounted at the body, a driving unit for driving the wheel (2), a sensor (71) positioned at the main body, for sensing an inclined direction of the main body (1), and a control unit for controlling the driving unit according to the inclined direction of the main body (1) sensed by the sensor (71). In this configuration, the posture of the main body (1) of the vacuum cleaner can be controlled according to the inverted pendulum control theory. Therefore, the main body (1) of the vacuum cleaner can maintain the posture thereof not to fall down.

Abstract: A dust separator for a vacuum cleaner including a body having a pair of spaced apart ends, a first air inlet formed in the body and being configured to receive an air flow containing dust, and a dust outlet formed inwardly of the spaced apart ends and apart from the first air inlet to discharge dust separated in the body, is provided. In addition, a cross-sectional area of the body at the dust outlet is greater than a cross-sectional area of the body at the first air inlet.

Abstract: The present exemplary embodiments relate to a dust separating apparatus for a vacuum cleaner. The dust separating apparatus for a vacuum cleaner according to present exemplary embodiments includes a cyclone in which a plurality of cyclone airflows is formed; a dust outlet for discharging dust separated by the plurality of cyclone airflows; and a dust container for storing dust discharged from the dust outlet, wherein the cyclone includes a body in which air flows along an inner surface thereof, and a pair of sides, each of the sides forming one of both side surfaces of the body and defining an outlet for discharging air.

Abstract: A distribution unit for a dust separating apparatus of a vacuum cleaner is provided. The distribution unit distributes air and dust to the dust separation unit includes a body having an inlet for introducing the air and dust to the body, a plurality of branch passages for distributing the air introduced into the body to the dust separation unit, and a main passage for connecting the inlet with the branch passages, and wherein a passage cross-sectional area of the main passage at the branch passage is greater than a passage cross-sectional area of the inlet.

Abstract: A dust collection unit for a vacuum cleaner includes a first filtering chamber filtering relatively large foreign objects, a second filtering chamber filtering relatively small foreign objects when air exhausted from the first filtering chamber is introduced into the second filtering chamber, an exhaust member disposed above the filtering chambers to guide airflow, a storing chamber disposed under the filtering chambers to store the foreign objects filtered in the filtering chambers, a sealing member sealing bottoms of the filtering chambers, and a rectifying unit formed on an exhaust side of the second filtering chamber to rectify airflow, thereby reducing noise generated by the airflow.

Abstract: The present invention provides a fan apparatus which can reduce noise and enhance fan efficiency by employing a BLDC motor that can make stable drive of the fan and increase an air flow rate, and an outdoor unit of a front suction/discharge type in an air conditioner that can enhance heat exchange efficiency by employing the same.

Abstract: Fan apparatus including a fan, a shaft coupled to the fan for transmission of driving force from a motor to the fan, a rotor bushing of an insulating material joined to a rear end portion of the shaft, a rotor joined to the rotor bushing for transmission of the driving force to the shaft through the rotor bushing, and a stator mounted so as to be positioned on an inside of the rotor to form a BLDC motor together with the rotor, thereby reducing noise and enhancing fan efficiency by employing the BLDG motor which can make stable operation of the fan and increase an air flow rate.

Abstract: The present invention discloses a vacuum cleaner including a vacuum cleaner main body having a suction pump, a suction nozzle portion for sucking impurities by a suction force supplied by the suction pump, a suction passage for connecting the suction nozzle portion to the suction pump, an agitator installed at the suction passage, and a driving unit for making the agitator perform linear translation. As the agitator is formed narrow and long, the bottom surface of the suction nozzle portion can maintain a small suction area. Therefore, the vacuum cleaner attains a high surface pressure which is an advantage of an ordinary type suction nozzle portion, and a high drag coefficient of impurities which is an advantage of a brush type suction nozzle portion.
