- the cyclone-type dust collecting apparatus comprises a cyclone body 50 , a dirt-collecting receptacle 60 , a filter assembly 70 , and a dusting member 90 .
- the cyclone body 50 is divided into an upper and lower bodies 51 , 52 .
- the upper and lower bodies 51 , 52 are connected by a plurality of screws 53 .
- the lower body 52 has a first connection pipe 54 connected with an extension pipe 1 a on the suction port side of the cleaner, and an air inlet port 55 connected with the first connection pipe 54 formed thereon.
- the upper body 51 has a second connection pipe 56 connected with an extension pipe 1 b on the cleaner body side, and an air discharge port 57 connected with the second 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 the air inlet port 55 in an oblique direction with respect to the cyclone body 50 . Accordingly, a vortex is created inside the cyclone body 50 and the dirt-collecting receptacle 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 the air discharge port 57 of the cyclone body 50 .
- the dirt-collecting receptacle 60 creates a vortex with respect to the flown in air in cooperation with the cyclone body 50 , and also collects the contaminants separated from the air by the vortex.
- the filter assembly 70 is disposed at the air discharge port 57 of the cyclone body 50 and prevents the contaminant collected in the dirt-collecting receptacle 60 from flowing back through the air discharge port 57 .
- Such filter assembly 70 comprises a pipe member 71 connected to the air discharge port 57 , a cover 73 , a shaft 75 rotatably supporting the cover 73 , and a rotation filter 77 disposed on the lower portion of the pipe 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.
- the cover 73 is connected to the upper portion of the pipe member 71 .
- the cover 73 is fitted into the upper portion of the pipe member 71 .
- the cover 73 has a plurality of ribs provided around the shaft portion 73 a at predetermined intervals for allowing air to be discharged.
- the shaft portion 73 a has an upper end of the shaft 75 rotatably connected thereto by a bearing 76 . Therefore, the shaft 75 is disposed to pass through the pipe member 71 without interfering with it.
- the rotation filter 77 is disposed at the lower end of the pipe member 71 , and rotatably supported by the shaft 75 .
- Such rotation filter 77 comprises a turbine 81 fitted into the lower portion of the pipe member 71 , a filtering net 83 covering the outer circumferential surface of the turbine 81 , and a reverse prevention member 85 connected with the lower end of the turbine 81 .
- the turbine 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 the pipe member 71 .
- the filtering net 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.
- the reverse prevention member 85 is fixed at the lower end of the shaft 75 by the screws 53 inside the lower portion of the turbine 81 . Accordingly, the rotation filter 77 can rotate together around the shaft 75 .
- the reverse prevention member 85 has a flange portion 85 a with the lower end extended outward thereby preventing light contaminants from flowing back.
- the pipe member 71 has the dusting member 90 disposed at the outer end portion thereof. That is, one end of the dusting member 90 is fixed to an end of the pipe member 71 and the other end is positioned on the outer surface of the filtering net 83 .
- a side of the dusting member 90 that is, the lower side of the dusting member 90 has a dusting brush 91 disposed thereon in contact with the filter net 83 .
- the dusting member 90 is disposed to decline in the rotation direction of the turbine 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 the rotation filter 77 rotates, and fall down without remaining on the dusting member 90 .
- Such dusting member 90 may be fastened to the pipe member 71 by a screw, or connected by a generally-known connection means.
- the cyclone-type dust collecting apparatus is used with itself being connected to the extension pipes 1 a , 1 b of the cleaner as a conventional cyclone-type dust collecting apparatus.
- the dusts and contaminants are flown in through the first connection pipe 54 and the air inlet port 55 in the oblique direction with respect to the cyclone 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-collecting receptacle 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-collecting receptacle 60 .
- the air is flown into the pipe member 71 through the filtering net 83 and the turbine 81 of the filter assembly 70 by an air stream rising back up at the bottom of the dirt-collecting receptacle 60 .
- the air flown into the pipe member 71 is discharged through the extension pipe 1 b .
- a part of the contaminants rising with the air stream in the dirt-collecting receptacle 60 is blocked by the reverse prevention member 85 thereby descending back with the vortex.
- the contaminants not separated by the reverse prevention member 85 are filtered by the filtering net 83 . Accordingly, fine dusts are caught on the filtering net 83 , and clean air passes through the filtering net 83 and is discharged through the turbine 81 .
- the turbine 81 is rotated clockwise, that is, in the direction A, by the air being discharged. Therefore, the filtering net 83 and the turbine 81 rotate together while constantly being in contact with the dusting member 90 thereby having the contaminants covering the filtering net 83 automatically dusted off by the dusting member 90 . Accordingly, airways can be prevented from being blocked by dusts covering the filtering net 83 .
- the filtering net 83 is automatically dusted, there is no need of separately dismounting and dusting the filter assembly 70 when emptying the dirt-collecting receptacle 60 .
- the embodiment of the present invention illustrates a filter assembly 70 with a single dusting member 90
- the dusting member 90 may be disposed in plural numbers at predetermined intervals.
- 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.
- 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.
