The sealing pad 140 may be stably assembled by arranging the groove 135 and the protrusion 125 to be coupled to the outside of the upper case 120 and the lower case 130 in order to effectively seal the sealing pad 140.

The cyclone separator 150 is detachably installed in the case dust collecting chamber 121 of the upper case 120 to separate the case dust collecting chamber 121 to both sides, and the case has a relatively heavy dust or foreign substance by centrifugal force. The outer cylinder 160 separating the dust collecting chamber 121 and the inner cylinder separating the relatively small dust or foreign matter into the case dust collecting chamber 121 by once again filtering the air filtered by the outer cylinder 160. It is made of a portion 170.

The shape of the upper surface 161 of the outer cylindrical portion 160 corresponds to a predetermined space shape formed by the guide portion 124 in the upper case 120, and the inner cylindrical portion 170 on the upper surface 161 of the outer cylindrical portion 160.

The dust collecting case 110, the cyclone separator 150, the filtering device 180, and the filter 190 may be assembled and separated from each other, and may be reused after removing foreign substances.

The operation of the present invention having the configuration as described above will be described.

First, the vacuum collecting dust collector 100 configured as described above is inserted into the dust collecting chamber (not shown) of the vacuum cleaner, and sucks air containing dust or foreign matter through the suction hole 122. At this time, since the suction hole 122 is disposed eccentrically with the longitudinal axis C of the guide portion 124 formed in the upper case 120, the cyclone separator mounted at a position corresponding to the guide portion 124 It is also eccentric with the center of 150. Therefore, the sucked air is introduced while rotating in the cyclone separator 150, the air is more easily rotated by the internal dome-shaped space of the cone-shaped assembly protrusion 133 formed in the lower case 130.

When the air containing the dust or foreign matter is introduced into the cyclone separator 150 while rotating as described above, the relatively heavy dust or foreign matter tries to escape from the lower portion of the cylindrical cyclone separator 150 by centrifugal force. . The dust or foreign matter is partially cut out of the lower sidewall portion 165 of the outer cylindrical portion 160, and is separated and discharged to the outside of the cyclone separator 150 through the cutting portion 169. The dust or foreign matter thus separated is accumulated in the case dust collecting chamber 121 formed on both sides of the upper case 120 by the side wall portion 165 of the outer cylindrical portion 160.

However, in addition to the dust or foreign matter separated by the case dust collecting chamber 121 in the outer cylindrical portion 160 primarily, relatively light dust or foreign matter still remains in the cyclone separator 150 to rotate, and such dust or foreign matter Rotates and rises to the top of the cyclone separator 150. Dust or foreign matter is raised to the upper portion of the cyclone separator 150 is as follows.

Since the inner cylindrical portion 170 of the cyclone separator 150 is tapered so that the width thereof is narrowed downward, the space between the outer cylindrical portion 160 and the inner cylindrical portion 170 becomes narrower as the upper portion is substantially upward. You lose. When the gap between the outer cylindrical portion 160 and the inner cylindrical portion 170 is narrowed because the flow rate is faster due to the narrow gap, relatively small dust or foreign matter is sucked to the upper portion 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 122 is also transferred to the case dust collecting chamber 121 through the cutout 169 partially disposed on the upper portion of the outer cylindrical portion 160 by centrifugal force. It will be separated and discharged secondarily.

The relatively small dust or foreign matter separated and discharged to the case dust collecting chamber 121 is dispersed again and accumulated on the inner surface of the mesh filter 185 of the filtering device 180 to separate the air containing dust or foreign matter in the third order. Will be discharged.

As described above, the air in which the dust or the foreign matter is separated in the first and second directions is rotated upward and discharged to the outside through the discharge hole 123 formed on the cyclone separator 150, and the third or third dust or the foreign matter by the filtering device 180. The separated air passes through the mesh filter 185 and is discharged to the outside. Since the air contains fine dust or foreign matters, the exhaust hole 123 and the filtering device to completely filter out such dust or foreign matters ( The filter 190 is mounted outside the 180.

The filter 190 is for filtering the air discharged upward from the cyclone separator 150 or for filtering the air passing through the filtering device 180, may be disposed inside the dust collecting case 110.

In the conventional vacuum cleaner dust collector, when the air containing dust or foreign matter is sucked, the dust or foreign matter is directly accumulated on the filter attached to one surface of the dust collector to weaken the suction force, according to a preferred embodiment of the present invention Since the dust collector for the vacuum cleaner separates dust or foreign matter into the case dust collecting chamber 121 by centrifugal force and upward force, the air containing only fine dust or foreign matter is purified again by the filter 190, so that the filter 190 ) Less dust and foreign matter will accumulate in the suction force will not be reduced. 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, the case dust collecting chamber 110 of the dust collecting case 110 Dust or foreign matter will accumulate at 121.

While the vacuum bag dust bag of the prior art was difficult to reuse, since the dust collector 100 for a 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 Separating the 110 up and down to remove dust or foreign matter, and can be used again after washing the dust collecting case 110, cyclone separator 150, filtering device 180, filter 190.

As described in detail above, according to the dust collector for the vacuum cleaner of the present invention, 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 reuse after cleaning Since dust and foreign substances are separated by a cyclone separator and a filtering device, fine dust and foreign substances are filtered out by a filter, and dust or foreign substances are accumulated in the filter so that the suction power is not lowered, so dust collection performance is improved. Has

In addition, the cyclone separator, the filtering device and the dust collector are integrated to reduce the volume of the dust collector, thereby reducing the volume of the outer case of the cleaner, thereby improving the mobility of the vacuum cleaner.

While the invention has been shown and described with respect to certain preferred embodiments thereof, the invention is not limited to the embodiments described above, and is typically defined in the art to which the invention pertains without departing from the spirit of the invention as claimed in the claims. Anyone with knowledge of the world can make many variations.
