  • Patent number: 7932688
    Abstract: A cleaner that can be operated at motive force of sufficient strength by using a battery voltage as well as by using a AC voltage. The cleaner uses a low-resistance-mode motor to rotate a collecting fan. The low-resistance-mode motor is driven by a motor driver. The motor driver drops a DC voltage converted from the AC voltage, depending on whether the AC voltage is received. Depending on whether the AC voltage is received, the motor driver drives the low-resistance-mode motor using one of the battery voltage and the dropped voltage.

  • Patent number: 7898209
    Abstract: A cleaner that can automatically respond to a change in an AC voltage and a voltage of a battery. In the motor, a motor for rotating a collecting fan is driven by a motor driver. The motor driver drives the motor using a voltage from a voltage selector. The voltage selector switches between a low-level voltage of the battery and a high-level voltage derived from the AC voltage to be supplied to the motor driver.

  • Patent number: 7847511
    Abstract: 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.
