  • Patent number: 7434293
    Abstract: A vacuum cleaner is disclosed. The vacuum cleaner includes a motor casing to receive a driving motor with an air outlet through which air from a dust collecting chamber flows. The vacuum cleaner includes a cleaner body with a driving chamber that receives the motor casing therein. An air discharge unit is disposed at the cleaner body through which air which flows from the motor casing of the driving motor is discharged to an outside of the driving chamber. Noise reduction is achieved by guiding and reversing a discharging direction of air discharged from the motor casing at least two times.

  • Patent number: 7260868
    Abstract: A simple dust collector includes a housing, a base plate horizontally separating the interior of the housing to form a motor chamber for fix a motor to rotate a fan covered by a fan cover under the base plate. A sucking passageway and a wind-exhausting hole are formed under the fan cover, and a tube joint is connected with the sucking passageway connected to a dust tube. The plurality of wind outlets are formed in a lower section of the housing and sealed by an airy cloth ring to filter dust from wind. The housing has an opening in a lower side and the opening is fitted with a dust bag for dust carried by the wind generated by the fan from the passageway and swirled by centrifugal force caused by rotation of the fan to fall and be collected in the dust bag.
