    摘要： A system and method for driving a drawer of a refrigerator and a refrigerator employing this system is provided. This system and method allows the drawer to substantially immediately and automatically stop when the drawer encounters an obstacle. This type of automatic control of the drawer may enhance the safe operation of the drawer, prevent injuries to users, and prevent overload and subsequent malfunction of a drive motor used to move the drawer.

    摘要： A fan assembly. The fan assembly includes a rotation shaft, a rotor coupled to the rotation shaft, a stator disposed inside the rotor, and a fan including a hub having a receiving space therein, and a plurality of blades disposed at a circumference of the hub, and coupled to the rotation shaft such that the rotor is spaced from an inner surface of the hub respectively in axial and radial directions, thereby preventing a transfer of vibration of a permanent magnet to the outside, and thus reducing the generation of noise due to the vibration.

    摘要： Disclosed herein is a method for determining a frequency of a power brush in a vacuum cleaner. According to the method of the present invention, a mechanical oscillation frequency of a driving unit, which includes a brush body reciprocated within a range of prescribed angles, and a torsion bar for providing a prescribed elastic force to angular rotation of the brush body, is set equally to a driving frequency of a power supply unit, which drives the driving unit, or is set a prescribed percentage higher or lower than the driving frequency of the power supply unit, so that the driving unit can resonate. A large amount of movement is obtained using a small amount of power by means of the resonance.

    摘要： A movement structure for a drawer of a refrigerator is provided that allows a storage box to be automatically withdrawn from or inserted into a main body of the refrigerator. The structure may include a rolling mechanism that rolls along a guide mechanism coupled to the storage box to facilitate and guide the movement of the storage box and maintain alignment relative to the main body of the refrigerator. A drive motor may provide a rotational force to the rolling mechanism to automate the movement of the storage box.
