A mesh filter may be added to the outside of the inner cylindrical part 230 to separate fine dust or foreign matter more effectively.

The filter 300 is a device for filtering the air filtered out dust or foreign matter to the cyclone separator 200 through the discharge hole 114 at the rear of the upper case 110 to be more cleanly discharged to the outside, and the upper case 110. ) It can be attached to the back and can be washed.

Detachability of the filter 300 is possible by the frame 310 that can be attached and detached to the dust collecting case 100, the filter 300 is bent and inserted in the frame 310 regularly for better dust collection performance.

When the filter 300 is attached to the dust collecting case 100, the adhesion pad 320 is also attached to the rear surface of the upper case 110 in order to minimize the phenomenon that the filter 300 is excited and the filtration efficiency of air is lowered.

In the dust collector for a vacuum cleaner according to a preferred embodiment of the present invention, HEPA (High Efficiency Particulate Air) filter is used, but the type of filter is not limited thereto.

The dust collecting case 100, the cyclone separator 200, and the filter 300 described above may be assembled and separated from each other, and may be reused after removing foreign substances.

4 and 5, the operation of the dust collector for a vacuum cleaner according to a preferred embodiment of the present invention having the configuration as described above will be described.

First, the dust collector configured as described above is inserted into the vacuum cleaner, and sucks air containing dust or foreign matter through the suction hole 111. At this time, since the suction hole 111 is disposed to be eccentric with the longitudinal center line C of the guide portion 113 formed in the upper case 110, the cyclone separator mounted at a position corresponding to the guide 113 ( It is also eccentric with the center. Therefore, the sucked air is introduced while rotating in the cyclone separator 200, the air is more easily rotated by the internal dome-shaped space of the cone-shaped assembly protrusion 121 formed in the lower case 120.

When the air containing the dust or foreign matter enters into the cyclone separator 200 while rotating as described above, the relatively heavy dust or foreign matter tries to escape from the lower portion of the cylindrical cyclone separator 200 by centrifugal force. Since the dust or foreign matter is partially cut off the lower sidewall 223 of the outer cylindrical portion 220, the dust or foreign matter is discharged to the outside of the cyclone separator 200 through the cutout 225. The dust or foreign matter thus separated is accumulated in the dust collecting chambers formed on both sides of the upper case 110 by the side wall 223 of the outer cylindrical portion 220.

However, in addition to the dust or foreign matter separated into the dust collecting chamber in the outer cylindrical portion 220 primarily, relatively light dust or foreign matter still remains in the cyclone separator 200 to rotate, and the dust or foreign matter rotates while the cyclone separator is rotated. 200 will rise to the top. The principle that the dust or foreign matter rises above the cyclone separator 200 is as follows.

Since the inner cylindrical portion 230 of the cyclone separator 200 is tapered so that its width decreases downward, the space between the outer cylindrical portion 220 and the inner cylindrical portion 230 becomes narrower as the upper portion thereof is substantially upward. You lose. When the gap between the outer cylindrical portion 220 and the inner cylindrical portion 230 is narrowed, the flow rate is increased due to the narrow gap, so that the relatively small dust or foreign matter is sucked upward by the high flow rate. Fine dust or foreign matter that has risen to the top while being rotated by the eccentric designed suction hole 111 is also discharged to the dust collecting chamber through the cutout 225 partially disposed on the upper portion of the outer cylindrical portion 220 by centrifugal force.

As described above, the air in which the dust or the foreign matter is separated from the first and second is rotated to be discharged to the outside through the discharge hole 114 formed on the cyclone separator 200. Such air contains fine dust or foreign matter. Therefore, the filter 300 is mounted outside the discharge hole 114 to completely filter out such dust or foreign matter. The filter 300 is for filtering the air discharged from the cyclone separator 200 and may be disposed inside the dust collecting case 100.

In the conventional dust collector for vacuum cleaner, when the air containing dust or foreign matter is sucked, dust or foreign matter is directly accumulated on the filter attached to one surface of the dust collector, so as to weaken the suction force, according to a preferred embodiment of the present invention. The dust collector for the vacuum cleaner separates dust or foreign matter into the dust collecting chamber by centrifugal force and lift force, and then purifies the air containing only fine dust or foreign matter by the filter 300 again, so that the filter 300 has no dust or foreign matter. This builds up less so that the suction force is not lowered. Therefore, dust collection performance is always improved due to a constant suction force.

When the air containing various dusts or foreign substances is sucked through the same process as described above, the dust or foreign substances are separated, and filtered and discharged again in the air, both dust collecting chambers of the dust collecting case 100 are Dust or foreign matter will accumulate on the floor.

While the vacuum bag dust bag of the prior art was difficult to reuse, since the dust collector for the vacuum cleaner according to the preferred embodiment of the present invention is easy to separate and assemble, when the dust or foreign substance is filled, the dust collecting case 100 It can be separated up and down to remove the dust or foreign matter, can be used again after washing the dust collecting case 100, the cyclone separator 200, the filter 300.

As described above, the dust collector for the vacuum cleaner according to the preferred embodiment of the present invention has the following effects.

First, by adopting a dust collector structure that is easy to separate and assemble and washable, it is more convenient to manage than a dust bag that is difficult to remove dust or foreign matter, and can be reused after cleaning.

Second, since the dust or foreign matter is first separated by the cyclone separator to filter out the fine dust or foreign matter by the filter, the dust or foreign matter is less accumulated in the filter so that the suction power is not lowered, the dust collection performance is improved.

Third, since the cyclone separator and the dust collector are integrated to reduce the volume of the dust collector, the volume of the outer case of the cleaner can be reduced, thereby improving the mobility of the vacuum cleaner.

Although described above with reference to a preferred embodiment of the present invention, those skilled in the art will understand that all modifications and changes can be made without departing from the spirit and scope of the present invention.
