Abstract
Abstract 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. <IMAGE>

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
107 words
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, wherein 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.
Claim 2
Dependent Claim
134 words
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, wherein the pre-filter is arranged to be rotatable, a spiral rib is formed at
an outer periphery of the pre-filter, and the device is equipped with a
rotating means for rotating the pre-filter.
Claim 3
Dependent Claim
26 words
The dust-collecting device of Claim 2, wherein a filter
portion of the pre-filter is designed to be located in a lower portion in the
dust-collecting case.
Claim 4
Dependent Claim
29 words
The dust-collecting device of Claim 2, wherein the pre-filter
is provided with elastic protrusions which hit against the main filter
through rotation thereof to make the main filter oscillate.
Claim 5
Dependent Claim
32 words
The dust-collecting device of Claim 2, wherein the rotating
means includes a handle and a gear mechanism for connecting a
rotating axis of the handle and an attaching plate for the pre-filter.
Claim 6
Dependent Claim
43 words
The dust-collecting device of Claim 2, wherein the rotating
means includes a slide lever and a gear mechanism which is connected
to the slide lever in case the slide lever is slid in either direction for
rotating the pre-filter in a specified direction.
Claim 7
Dependent Claim
35 words
The dust-collecting device of Claim 1, wherein the device is
provided with a grip, and a fulcrum for opening and closing the bottom
lid is provided on a same side as that of the grip.
Claim 8
Dependent Claim
35 words
The dust-collecting device of Claim 1, wherein the device is
provided with a grip, and a fulcrum for opening and closing the bottom
lid is provided on an opposing side as that of the grip.
Claim 9
Dependent Claim
212 words
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, wherein the vacuum cleaner comprises a handle for operating the main
body extending upward from a front surface side of the main body of the
vacuum cleaner, the dust-collecting device is fitted to the front surface
side of the main body of the vacuum cleaner in a freely attachable and
detachable manner, and a grip of the dust-collecting device is formed to
extend downward from the handle in a successive manner for operating
the main body.
