A dust-collecting device for a vacuum cleaner comprising a dust-collecting case which is fitted into a suction path extending from a suction nozzle to a motor fan and from which accumulated dust can be discharged by opening a bottom lid of the dust-collecting case, and a cylindrical filter fitted into the dust-collecting case. The filter is arranged to be rotatable, a spiral rib is formed at an outer periphery of the filter, and the device is equipped with a rotating means for rotating the filter. Dust which cannot be discharge by its own weight since it is in a compressed state can be pushed out through the spiral rib formed on the outer periphery of the filter by rotating the filter, so that dust accumulated within the dust-collecting case in a compressed state can be easily discharged.
A dust-collecting device for a vacuum cleaner comprising a dust-collecting case which is fitted into a suction path extending from a suction nozzle to a motor fan in a freely attachable and detachable manner and from which accumulated dust can be discharged by opening a bottom lid of the dust-collecting case, and a cylindrical filter fitted into the dust-collecting case for filtering dust contained in air which is taken in into the dust-collecting case,
A dust-collecting device for a vacuum cleaner comprising a dust-collecting case which is fitted into a suction path extending from a suction nozzle to a motor fan in a freely attachable and detachable manner and from which accumulated dust can be discharged by opening a bottom lid of the dust-collecting case, a cylindrical pre-filter fitted into the dust-collecting case for filtering coarse dust contained in air which is taken in into the dust-collecting case, and a cylindrical main filter fitted into the pre-filter for filtering minute dust contained in air which has been filtered by the pre-filter for eliminating coarse dust,
An upright type vacuum cleaner with a dust-collecting device for a vacuum cleaner being fitted to a main body of the upright type vacuum cleaner in a freely attachable and detachable manner, the dust-collecting device comprising a dust-collecting case which is fitted into a suction path extending from a suction nozzle to a motor fan in a freely attachable and detachable manner and from which accumulated dust can be discharged by opening a bottom lid of the dust-collecting case, and a cylindrical filter fitted into the dust-collecting case for filtering dust contained in air which is taken in into the dust-collecting case, in which the filter is arranged to be rotatable, a spiral rib is formed at an outer periphery of the filter, and the device is equipped with a rotating means for rotating the filter,
