For this, an elastic member such as aspring 94 is provided inside of thefilter coupling confirmer 93, and thespring 94 applies pressure to an inner surface of thefilter coupling confirmer 93 so as to project outside through thegroove 56 b formed on the side of thetop lid 56 by restoring force of the spring when thefiltering device 80 is separated from thefilter fixing device 90 of thetop lid 56. In the present invention, because thedust collecting container 51 is coupled to the top lid in a method of inserting an upper end of thedust collecting container 51 into the inside of thetop lid 56, it is impossible that thetop lid 56 tightly shuts thedust collecting container 51 when thefilter coupling confirmer 93 is projected to a side of thetop lid 56. - A process of attaching and detaching the
filtering device 80 to the filter fixing device of thetop lid 56 is described as follows. - First, when the
filtering device 80 is separated from thetop lid 56, thefilter coupling confirmer 93 is projected to the side of thetop lid 56 by the restoring force of thespring 94. Accordingly, as mentioned above, it is impossible that thetop lid 56 tightly shuts thedust collecting container 51, and, at this time, since thetop lid 56 and a top surface of the dust collectingassembly receiving recess 22 interfere with one another, the dust collecting assembly is not mounted on thecleaner body 20. - Next, for mounting the filtering device to the
top lid 56, if thefiltering device 80 is rotated such that thepush projection 83 b faces the fixingend 92 b when thegroove 83 a of the top end supporter and thepush projection 83 b correspond to thecoupling projection 91 a of the filter fixing member and the insertinggroove 92 a of the shifting member respectively, the push projection applies pressure to the insertinggroove 92 a so as to move the shiftingmember 92 to an opposite direction of thefilter coupling confirmer 93. If the filtering device is rotated more, thepush projection 83 b is caught by the fixingend 92 b, and thetop end supporter 83 is fixed by the coupling projection. Therefore, thefilter coupling confirmer 93 is moved in the same direction of the shifting member and positioned within the side of the top lid such that thetop lid 56 is able to tightly shut thedust collecting container 51 without interference and thedust collecting assembly 50 is completely mounted on thecleaner body 20 without interference. - For discharging the clean air cleaned by the cyclone method and the filtering device as abovementioned to the outside of the dust collecting space in the dust collecting container, an
inner flow tube 57 is provided in the dust collecting assembly, the inner flow tube having a lower end being coupled to the outlet of thedust collecting assembly 53 and an upper end being coupled to a predetermined location, and more particularly, to the lower end of thefiltering device 80 so as to communicate with the cleanair guiding passage 84 of the filtering device, and forming a passage for discharging the clean air from the dust collecting space, the clean air separated from the impurities. - Owing to the construction abovementioned, the polluted air drawn into the
dust collecting assembly 50 is cleaned firstly by the cyclone principle which separates large and heavy impurities, and cleaned secondly by passing through thefiltering device 80 which filters the minute dust particles, and then discharged to the outside through the clean air guiding passage of thefiltering device 80, the inner flow tube 57 a, and the clean air outlet of the cleaner body having the fan. - It is, of course, obvious that the microscopic dust is additionally filtered before the air is discharged to outside of the vacuum cleaner by providing a third filter (not shown) at a predetermined location of the clean air conduit. The filters may include HEPA filters.
- However, since the
dust collecting assembly 50 with the above mentioned structure separates and collects impurities such as dust according to the cyclone principle, there is a problem that the impurities such as dust piled up at a lower part of thedust collecting container 51 is risen by spiraled air in a process of spiral flow of the polluted air entered into the dust collecting assembly, and thereby lowering dust collecting efficiency. - Therefore, as illustrated in
FIG. 8 , it is desirable that aseparation plate 58 is provided in thedust collecting container 51 for dividing the dust collecting space of thedust collecting container 51 into an upper space and a lower space. In more detail, theseparation plate 58 is provided in the vicinity of thefiltering device 80 and theinner flow tube 57 such that the impurities separated from the upper space of thedust collecting container 51 is moved to the lower space of the dust collecting container, and the impurities collected in the lower space of the dust collecting container is prevented from being interfered by the air flow. In other words, at least onehole 58 a, through which large dust particles pass, is provided on an outline of theseparation plate 58 such that relatively large dust particles are moved to the lower part of theseparation plate 58, the large dust particles among the impurities included in the polluted air drawn through the dust collecting assembly inlet. - The
separation plate 58 is provided to be opened or closed by rotation for discharging the impurities collected in the lower part of theseparation plate 58 when thedust collecting assembly 51 is upside down for discharging thedust collecting assembly 50. - For this, the
separation plate 58 is configured with two semicircular plates rotated upwardly, or formed in a round form or an elliptic form (not shown) having the center of gravity which is one-sided about the rotation axis. - The
separation plate 58 separating the inside of thedust collecting container 51 increases dust collecting efficiency by preventing the impurities such as dust piled up on the lower part of thedust collecting container 51 from being risen or rotated by air flow, particularly spiraled air in the dust collecting assembly. - Next, the referring to
FIG. 9 toFIG. 11 , a second embodiment of the dust collecting assembly provided at the vacuum cleaner in accordance with the present invention will be described. - Referring to
FIG. 9 toFIG. 11 , thedust collecting assembly 500 in accordance with the second embodiment includes adust collecting container 510 formed in a cylindrical form, having an opened top and having a dust collecting space for collecting the impurities therein, aninlet 520 provided on a rear upper side of the dust collecting container for sucking in polluted air, anoutlet 530 provided on a rear lower side of the dust collecting container, a dust collecting container handle 540 provided on a front outer wall of the dust collecting container, afiltering device 800 detachably coupled on the upper surface of the dust collecting container, aninner flow tube 570 for guiding clean air separated from the impurities in the filtering device to the outside of the dust collecting container, and aseparation plate 580 for separating the dust collecting space of thedust collecting container 510 into an upper part and a lower part. - In describing the second embodiment of the dust collecting assembly, the same reference numbers will be used to refer to the same or like parts of the first embodiment, and detailed description for the same parts will be omitted.

It is desirable that thebottom supporter 594 b and the fixingmember 594 c are incorporated into theside supporter 594 a. - Meanwhile, the
filtering device 800 is not detachable directly from the bottom surface of thetop lid 560, but inserted into and withdrawn from the top of the dust collecting assembly, i.e., from the top of the top lid through the top lid. - In this case, the
filtering device 800 formed in a cylindrical form and filtering impurities includes afilter 810 formed in a cylindrical form, afilter supporter filter 810, and a cleanair guiding passage 840 provided on an inner surface of thefilter 810. - The filter supporter includes a
bottom end supporter 820 supporting a lower end of thefilter 810 so as to maintain a circular form thereof, and atop end supporter 830 supporting a top end of the filter. - Except the
top end supporter 830, thefilter 810, thebottom end supporter 820, and the cleanair guiding passage 840 are the same as in the first embodiment of the dust collecting assembly, and description of which will be omitted. - In the second embodiment, the
top lid 560 for opening and closing the top surface of thedust collecting container 510 has a pass throughhole 561 perpendicularly bored in the center thereof so as to insert and withdraw thefiltering device 800. - The pass through
hole 561 is formed in a round form corresponding to the top end of thefiltering device 800, and more particularly, to thetop end supporter 830, and the top surface of the outline of the pass throughhole 561 has an end with a different length such that the bottom surface of the outline of thetop end supporter 83 is stably provided. - For fixing the
filtering device 800, aprojector 831 is radially projected from the circumferential surface of thetop end supporter 830, acoupling lever 562 is rotatably coupled with the top surface of thetop lid 560 by arotation axis 562 a or a hinge for binding theprojector 831, and alever mounting groove 563 is provided on the top surface of thetop lid 560 for preventing thecoupling lever 562 from being projected upwardly from the top surface of thetop lid 560, the lever mounting groove including theprojector 831 stably provided thereon and thecoupling lever 562 mounted thereon. - In other words, the
filtering device 800 is attached to or detached from thetop lid 560 by rotating thecoupling lever 562 about therotating axis 562 a and selectively fixing theprojector 831. - The filtering device may, of course, be fixed on the top lid by providing a male screw (not shown) at the upper end of the filtering device, i.e., on the outer circumferential surface of the upper end supporter, and a female screw (not shown) on the inner circumferential surface of the upper end supporter.
- In addition to the above structure, a
