    摘要： A brush vibrating apparatus for a vacuum cleaner. The brush vibrating apparatus includes a brush provided in a head portion of the vacuum cleaner and reciprocating and rotating for separating foreign substances from an object to be cleaned; support units provided on the head portion for rotatably supporting the brush; an elastic force supply unit installed between the brush and the support units for supplying elastic force from both sides of a center of the reciprocation of the brush to the center; and a driving force supply unit for supplying driving force, thereby minimizing noise and vibration generated from the reciprocation of the brush, thus allowing the vacuum cleaner to be operated in a smooth and calm state.

    摘要： A cleaner that can have the sufficient capability of collecting pollutant particles by a battery voltage as well as a AC voltage. The cleaner uses a switched reluctance motor to rotate a collecting fan. The switched reluctance motor is driven by a motor driver in one of a PWM mode or a pulse trigger mode. The motor driver drives the switched reluctance motor using one of the battery voltage and a DC voltage converted from the AC voltage, depending on whether the AC voltage is received. The PWM mode and the trigger mode are switched depending on whether the AC voltage is received. Accordingly, the cleaner makes it possible to reduce the time taken to clean up pollutant particles using the battery voltage to the time taken to clean up the pollutant particles using the AC voltage.

    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.
