[29] As shown in FIG. 3, the cyclone dust collector for a vacuum cleaner according to the present invention includes a cyclone body 110 and a waste collection unit 120. Since the structure and function thereof are the same as in the above-described conventional description, detailed description thereof will be omitted. Meanwhile, a grill assembly 250 is installed at an inlet side of the air discharge passage 105 of the cyclone body 110 to separate fine dirt contained in air directed to a vacuum source (not shown), and the grill assembly 250 is provided. Includes a grill body 160, a shielding member 270, a filter support 280, and a filter member 290.
[30] The grill body 160 is open at both ends and is formed in a tubular shape in which a plurality of first air inlet holes 163 are formed in a longitudinal direction along an outer circumferential surface thereof, and an inlet of the air discharge path 105 is formed at an upper end of the cyclone body 110. It is installed to cover one open end. Between each of the first air inlet hole 163, a guide vane 165 having a predetermined shape protrudes outwardly of the grill body 160 to incline the air flowing into the first air inlet hole 163. do. According to this, the air flowing into the grill body 160 from the cyclone body 110 flows in the tangential direction of the grill body 160, so that the air can pivot inside the grill body 160.
[31] The shielding member 270 is installed to cover the open lower end of the grill body 160, and the filter support part 280 disposed inside the grill body 160 is integrally formed when the shielding member 270 is mounted. The filter support part 280 is open at an upper end thereof to cover the outer periphery of the air discharge path 105, and a plurality of second air inlet holes 283 are formed along the outer circumferential surface thereof. According to this, when the shielding member 270 is mounted at the lower end of the grill body 160, the filter support part 280 is disposed inside the grill body 160, and the grill body through the first air inlet hole 163. Air introduced into the 160 is discharged to the air discharge path 105 via the second air inlet hole 283 of the filter support 280.
[32] On the other hand, the shielding member 270 includes a dirt backflow prevention portion 275 formed by forming a diameter of the lower edge portion larger than the diameter of the grill body 160. The dirt backflow prevention part 275 serves to switch the traveling direction of the dirt contained in the airflow directed toward the grill body 160 toward the swirl airflow of the cyclone dust collector 100.
[33] The filter member 290 is integrally formed on the outer circumference of the filter support part 280 to cover the second air inlet hole 283, and the second air inlet is formed through the first air inlet hole 163 of the grill body 160. It has a plurality of corrugations 295 to increase the contact area with air directed to the ball 283. Such, the pleats 295 of the filter member 290 is formed along the longitudinal direction on the outer circumferential surface of the filter member 290, it is not necessarily limited to this embodiment only to be formed along the circumferential direction of the filter member 290 It may be. According to this, the fine dust contained in the air flow directed to the air discharge path 105 without being filtered by the centrifugal force inside the cyclone body 110 can be filtered once more, thereby improving the filtering efficiency of the cyclone dust collector 100. have.
[34] On the other hand, the filter member 290 is separated from the cyclone dust collector 100 when water is contaminated by the fine dust contained in the air toward the air discharge path 105 as the cyclone dust collector 100 is used for a long time is washed with water This becomes possible and can be used as a permanent filter. In this case, it should be possible to suppress the deterioration of the filtering efficiency due to the deformation of the shape by the air pressure of the air flow toward the air discharge path 105. Accordingly, the filter member 290 is formed of a polyester material can be washed with water can be used semi-permanently, and can also suppress the deterioration of the filtering performance due to the shape change.
[35] The operation of the cyclone dust collector according to the present invention configured as described above will be described with reference to FIG. 4.
[36] When the vacuum source of the vacuum cleaner is driven, a swirling air flow is formed inside the cyclone body 110. Various dirts contained in the swirling air are separated from the swirling air by the centrifugal force of the swirling air, and the separated dirt is collected by the waste collecting unit 120.
[37] In this step, that is, some dirt that is not collected and separated from the airflow in the step of collecting dirt by centrifugal force is moved toward the grill assembly 250 by the rising airflow while turning along the center of the cyclone body 110.
[38] At this time, some of the dirt included in the air flow is reflected by hitting the dirt backflow prevention portion 275 of the shielding member 270, so that the traveling direction is switched back to the swirling air flow. Thus, the dirt is caught up in the swirling air again.
[39] Dirt, which is not separated from the upward airflow by the dirt backflow prevention part 275, is moved toward the first air inlet hole 163 of the grill assembly 250. Air is introduced into the grill assembly 250 through a curved flow path formed by the guide vane 165 and the first air inlet hole 163 due to the pressure difference between the grill assembly 250 and the outside.
[40] At this time, the fine dirt contained in the air flow is filtered by the filter member 290, so that only the purified air is moved toward the vacuum source. Therefore, it is possible to suppress the fine dirt from flowing into the vacuum source.
[41] On the other hand, when the filter member 290 is contaminated by fine dirt as the cyclone dust collector 250 is operated in this way, by separating the screw (S) for fixing the lower end of the shielding member 270 to the grill body 160, The shield member 270 is separated from the grill body 160. Thereafter, the filter member 290 is washed again after the water is washed again.
