- FIG. 5 is a drawing for illustrating the operation of a cyclone-type dust collecting apparatus according to an embodiment of the present invention.
- Hereinafter, a cyclone-type dust collecting apparatus for a vacuum cleaner according to a preferred embodiment of the present invention will be described in greater detail with reference to the accompanying drawings.
- FIG. 2 shows an exploded perspective view showing an upright-type vacuum cleaner employing a cyclone-type dust collecting apparatus according to an embodiment of the present invention.
- Referring to FIG. 2, the cyclone-type dust collecting apparatus according to an embodiment of the present invention comprises a
cyclone body 50, a dirt-collectingreceptacle 60, afilter assembly 70, and adusting member 90. - The
cyclone body 50 is divided into an upper andlower bodies lower bodies screws 53. Thelower body 52 has afirst connection pipe 54 connected with anextension pipe 1 a on the suction port side of the cleaner, and anair inlet port 55 connected with thefirst connection pipe 54 formed thereon. Theupper body 51 has asecond connection pipe 56 connected with anextension pipe 1 b on the cleaner body side, and anair discharge port 57 connected with thesecond connection pipe 56 formed thereon. - The contaminant-laden air drawn in through the suction port of the cleaner flows in through the
first connection pipe 54 and theair inlet port 55 in an oblique direction with respect to thecyclone body 50. Accordingly, a vortex is created inside thecyclone body 50 and the dirt-collectingreceptacle 60, and the contaminant included in the air is separated from the air by a centrifugal force formed by the vortex. - The dirt-collecting
receptacle 60 is removably connected to theair discharge port 57 of thecyclone body 50. The dirt-collectingreceptacle 60 creates a vortex with respect to the flown in air in cooperation with thecyclone body 50, and also collects the contaminants separated from the air by the vortex. - Referring to FIGS. 3 and 4, the
filter assembly 70 is disposed at theair discharge port 57 of thecyclone body 50 and prevents the contaminant collected in the dirt-collectingreceptacle 60 from flowing back through theair discharge port 57.Such filter assembly 70 comprises apipe member 71 connected to theair discharge port 57, acover 73, ashaft 75 rotatably supporting thecover 73, and arotation filter 77 disposed on the lower portion of thepipe member 71 as shown in FIG. 3. - The
pipe member 71 has a tubular structure with the upper end enlarged in a predetermined shape, and provides a path for air being discharged. Thecover 73 is connected to the upper portion of thepipe member 71. Thecover 73 is fitted into the upper portion of thepipe member 71. Thecover 73 has a plurality of ribs provided around theshaft portion 73 a at predetermined intervals for allowing air to be discharged. Theshaft portion 73 a has an upper end of theshaft 75 rotatably connected thereto by abearing 76. Therefore, theshaft 75 is disposed to pass through thepipe member 71 without interfering with it. - The
rotation filter 77 is disposed at the lower end of thepipe member 71, and rotatably supported by theshaft 75.Such rotation filter 77 comprises aturbine 81 fitted into the lower portion of thepipe member 71, a filteringnet 83 covering the outer circumferential surface of theturbine 81, and areverse prevention member 85 connected with the lower end of theturbine 81. Theturbine 81 has a plurality of rotation wings 81 a provided at predetermined intervals in the circumferential direction and therefore rotates by the air flown into thepipe member 71. The filteringnet 83 rotates together with the turbine on the outer circumferential surface for filtering fine dusts that are not separated by the centrifugal force inside the dirt-collecting receptacle. Thereverse prevention member 85 is fixed at the lower end of theshaft 75 by thescrews 53 inside the lower portion of theturbine 81. Accordingly, therotation filter 77 can rotate together around theshaft 75. Thereverse prevention member 85 has aflange portion 85 a with the lower end extended outward thereby preventing light contaminants from flowing back. - Meanwhile, the
pipe member 71 has the dustingmember 90 disposed at the outer end portion thereof. That is, one end of the dustingmember 90 is fixed to an end of thepipe member 71 and the other end is positioned on the outer surface of thefiltering net 83. A side of the dustingmember 90, that is, the lower side of the dustingmember 90 has a dustingbrush 91 disposed thereon in contact with thefilter net 83. - In addition, the dusting
member 90 is disposed to decline in the rotation direction of theturbine 81, that is, in a direction oblique to the direction of the rotation direction of the turbine 81 (FIG. 3). Therefore, the dusts and contaminants are brushed off the filter net 83 while therotation filter 77 rotates, and fall down without remaining on the dustingmember 90. Such dustingmember 90 may be fastened to thepipe member 71 by a screw, or connected by a generally-known connection means. - Hereinafter, the operation of the cyclone-type dust collecting apparatus according to the embodiment of the present invention structured as above will be described.
- As shown in FIG. 5, the cyclone-type dust collecting apparatus according to the embodiment of the present invention is used with itself being connected to the
extension pipes first connection pipe 54 and theair inlet port 55 in the oblique direction with respect to thecyclone body 50 together with the drawn in air by a suction force generated at the suction port of the cleaner. Accordingly, the air creates a vortex and descends towards the bottom of the dirt-collectingreceptacle 60. In that process, the dusts and contaminants included in the air are separated from the air by a centrifugal force and then collected in the dirt-collectingreceptacle 60. - Then, the air is flown into the
pipe member 71 through thefiltering net 83 and theturbine 81 of thefilter assembly 70 by an air stream rising back up at the bottom of the dirt-collectingreceptacle 60. The air flown into thepipe member 71 is discharged through theextension pipe 1 b. At this time, a part of the contaminants rising with the air stream in the dirt-collectingreceptacle 60 is blocked by thereverse prevention member 85 thereby descending back with the vortex. - In addition, the contaminants not separated by the
reverse prevention member 85 are filtered by thefiltering net 83. Accordingly, fine dusts are caught on thefiltering net 83, and clean air passes through thefiltering net 83 and is discharged through theturbine 81. Theturbine 81 is rotated clockwise, that is, in the direction A, by the air being discharged. Therefore, thefiltering net 83 and theturbine 81 rotate together while constantly being in contact with the dustingmember 90 thereby having the contaminants covering thefiltering net 83 automatically dusted off by the dustingmember 90. Accordingly, airways can be prevented from being blocked by dusts covering thefiltering net 83. In addition, since thefiltering net 83 is automatically dusted, there is no need of separately dismounting and dusting thefilter assembly 70 when emptying the dirt-collectingreceptacle 60. - While the embodiment of the present invention illustrates a
filter assembly 70 with a single dustingmember 90, the dustingmember 90 may be disposed in plural numbers at predetermined intervals. - According to the present invention described above, the cyclone-type dust collecting apparatus for a vacuum cleaner has a structure in which a filtering net is automatically dusted by a dusting member as the rotation filter of a filter assembly automatically rotates by air.
- Accordingly, the rotation filter can be prevented from being blocked by dusts and therefore cleaning efficiency can be improved and it becomes convenient for use since there is no need of separately cleaning the rotation filter.
- The foregoing embodiments and advantages are merely exemplary and are not to be construed as limiting the present invention. The present teaching can be readily applied to other types of apparatuses. The description of the present invention is intended to be illustrative, and not to limit the scope of the claims. Many alternatives, modifications, and variations will be apparent to those skilled in the art. In the claims, means-plus-function clauses are intended to cover the structures described herein as performing the recited function and not only structural equivalents but also equivalent structures.
