  An air, which swirls in the first chamber 370, enters the second chamber 380 through the second openings 335. The speed of the air stream increases as the air passes through the second openings 335. The air entering the second chamber 380 after having passed through the second openings 335 is guided by the guide elements 367, forming an acute angle with respect to the second lateral surface 332 of the first hood 330 so that the air swirling in the second chamber 380 circulates more rapidly than in the first chamber 370. To increase the velocity of the swirling air, the second openings 335 extend in a radial direction on an upper surface of the first hood 330 by providing a uniform gap between these openings. and are preferably arranged in the vicinity of the connecting portion of the first cover 330, which is connected to the second cover 350. Similarly, it is preferable that the guide members 337 are inclined downwardly in a direction of the air stream in the first chamber 370.

  Air introduced into the second chamber 380 swirls down an inner wall of the dirt collection receptacle 310. The dirt D is separated from the air by the action of gravity and also by the action a centrifugal force produced by the swirling air, and falls on the bottom of the dirt collection receptacle 310. The clean air is then discharged towards the vacuum generation source 130 through the element. grid shape 360, the air exhaust duct 313 and the exhaust outlet of the air 311, and this sequentially. Preferably, a plurality of first backward preventing members 317, each protruding from the bottom of the dirt collecting receptacle 310, are disposed along an outer circumference of the discharge pipe of the air 313 so as to facilitate the separation of the dirt. It is preferred that a second disc-preventing rearward-facing member 367 be disposed below the grid member 360. The second backward-preventing member 367 prevents air from rising from the bottom. of the dirt collection receptacle 310 towards the slots 361 of the grid member 360, preventing dirt from being exhausted through the grid member 360, together with the air.

  Fig. 6 shows a cyclone dust collection device according to a second embodiment of the present invention. A cyclone dust collection device 300 according to the second embodiment has a first opening 351 'which passes through an upper wall of a second hood 350'. In this case, the air may not swirl sufficiently in a first chamber 370, and the dust collection efficiency of the cyclone dust collection device 300 may be obtained with a degree as high as in the case of the collection device. 200 cyclone dust of the first embodiment. However, as the air enters from the first chamber 370 into a second chamber 380, the air swirls at a rate sufficient to separate the dust D from the air due to the presence of second openings 335 and guiding elements. 367, which increases the dust collection efficiency of the cyclone dust collection device 300.

  Although the dust collecting receptacle 310 is disposed on a lower portion of the dust collecting device 300 in the gravity direction, the receptacle 310 may be provided at other locations of the device 300. The present invention may be applied to any cyclone dust collection device if the cyclone dust collection device comprises the first chamber, into which air is sucked, the second chamber, in which the dirt is separated from the air so that centrifugal, and the partition wall separating the first and second chambers from each other and comprising the second openings and the guide elements.

  As previously described, due to the presence of the second openings 335 and guide members 337 formed on the partition walls 331, 332, which separate the first and second chambers 370 and 380 from each other, the swirling speed of the air in the second chamber 380 may be increased in a manner independent of the performance of the vacuum generation source 130. Therefore, the dust collection efficiency of the cyclone dust collecting device 300 is improved.

  Since the dust collection efficiency is ensured by the second openings 335 and the guide members 337, various modifications are possible in the arrangement or construction of the cyclone dust collection device 300 associated with the vacuum suction pipe. air 353 and the body 110 of the vacuum cleaner.

  Also, in accordance with the present invention it is possible that the first opening 351, through which the air is sucked, and the grid member 360, through which the air is forced out of the second chamber 380, are arranged in different spaces and are independent of each other. Therefore, since the air sucked by the first opening 351 can not penetrate directly into the grid member 360 without swirling in the dust collection receptacle 310, the dust collection efficiency of the collection device cyclone dust 300 can be improved.

  The above-mentioned embodiments and advantages are merely exemplary and should not be construed as limiting the present invention. The description of the present invention is intended to be illustrative and many changes, modifications and variations will be apparent to those skilled in the art.
