Referring to FIG. 1, an upright type vacuum cleaner according to an embodiment of the present invention includes a cleaner main body 10 partitioned into a dust collecting chamber 11 and a motor driving chamber (not shown), and rotated to the cleaner main body 10. A cyclone dust collecting device detachably installed in the dust collecting chamber 11 to collect and collect dust and foreign substances in the air sucked through the suction brush 13 and the suction brush 13, which are coupled to each other. 15).

According to the present invention, an air inlet 16a to which the suction hose 16 connected to the suction brush 13 is connected to the inner wall of the dust collecting chamber 11, and an exhaust hose 17 connected to the motor driving chamber are provided. Air outlets 17a connected to each other are formed.

As shown in FIGS. 2 and 3, the cyclone dust collector 15 includes a cover 20, a first cyclone cylinder 30, a second cyclone cylinder 40, a lower door 50, and dirt. A backflow prevention means is provided.

The cover 20 is formed in a substantially disk shape and has a first air inlet 21 at an edge thereof and an air outlet 23 at a central portion thereof. Therefore, when the cyclone dust collector 15 is mounted in the dust collecting chamber 11, the first air inlet 21 is connected to the air inlet 16a of the suction hose 16, the air outlet 23 ) Is connected to the air outlet 17a of the exhaust hose 17. In addition, an air outlet pipe 25 communicating with the air outlet 23 is provided at the central portion of the cover 20.

The first cyclone cylinder 30 has a cylindrical shape having an upper and lower portions open, the cover 20 is coupled to an upper opening, and the lower door 50 is coupled to a lower opening.

According to the present invention, the first cyclone barrel 30 cooperates with the cover 20 to guide the air sucked into the air inlet 21 into the vortex air flow to collect relatively particulate dirt contained in the air. . Reference numeral 31 in the drawing represents a handle installed on the outside of the first cyclone barrel (30).

On the other hand, the second cyclone cylinder 40 has a cylindrical shape of the upper and lower open type is gradually reduced in the lower portion, is disposed concentrically in the first cyclone cylinder 30 is coupled to the cover 20. In addition, the second cyclone cylinder 40 includes a grill portion 41 having a plurality of micro-pass holes 41a into which air rising inverted from the bottom of the first cyclone cylinder 30 is introduced, and the grill portion 41. And a second air inlet 43 for guiding air introduced through the air into the vortex air stream.

The circumference of the second cyclone cylinder 40 is such that the grill portion 41 can prevent the air flowing down while being inverted at the bottom surface while forming a vortex air flow inside the first cyclone cylinder 30. It is preferable to form discontinuously at predetermined intervals in the direction. In addition, the second air inlet 43 and the first air inlet 21 are preferably arranged so that a predetermined portion overlaps with each other.

The lower door 50 is installed to be opened and closed at a lower portion of the first cyclone barrel 30 so as to discard waste collected in the first and second cyclone barrels 30 and 40. According to this embodiment, the lower door 50 is screwed to the first cyclone cylinder (30).

The dirt backflow prevention means is for preventing the backflow of the dirt collected below the first cyclone barrel 30 and the second cyclone barrel 40, and the inner circumference of the first cyclone barrel 30. It consists of a main rib 33 protrudingly installed, and a non-return bar 51 provided on the lower door 50 so as to be disposed at a predetermined height from the lower center portion of the second cyclone cylinder 40.

The main rib 33 has a lower door 50 from the inner circumferential surface of the main rib 33 so as to more effectively prevent backwashing collected in the lower portion of the first cyclone barrel 30 along the inner circumferential surface of the first cyclone cylinder 30. It is formed to be inclined downward toward the side.

The backflow prevention rod 51 may be installed at the center of the second cyclone barrel 40 to minimize the flow of collected fine dust, thereby minimizing the backflow. In addition, the radially extending auxiliary ribs 53 protrude from the upper end of the backflow prevention rod 50. The auxiliary ribs 53 are for preventing backflow of the fine dust collected in the second cyclone barrel 40 on the outer circumference of the backflow prevention rod 50, and from the upper end of the backflow prevention rod 50. It is preferable to be inclined downward at a predetermined angle toward the 50 side.

Referring to the operating state of the upright vacuum cleaner according to the present invention having the configuration as described above are as follows.

First, the dust collector 15 drives the vacuum cleaner in a state coupled to the dust chamber 11. Then, the air including the dust and dirt on the surface to be cleaned is sucked through the suction brush 13 to the first air inlet 21 of the collecting device 15 through the suction hose 16 and the air inlet 16a. Air sucked in this way is lowered toward the lower door 50 while being guided into the vortex air flow by the cooperation of the cover 20 and the first cyclone barrel (30). At this time, relatively large particles of dirt contained in the air are first centrifuged and collected at the bottom by the vortex air flow in the first cyclone barrel 30.

On the other hand, the vortex air flow is reversed to rise in the bottom surface of the first cyclone cylinder (30). At this time, some of the collected waste may be flowed back along the inner circumferential surface of the first cyclone barrel (30). Such backwashed dirt is blocked by the main rib 33 and is no longer raised and collected to the bottom. That is, the dirt in the 1st cyclone cylinder 30 can be collected more effectively by the action of the main rib 33. In addition, since the main rib 33 is formed to be inclined toward the lower door 50 side, the main rib 33 is almost completely blocked from flowing back through the main rib 33.

As described above, the inverted and elevated vortex air flows through the grill part 41 and flows into the second air inlet 43. At this time, the air flowing into the second air inlet 43 is guided in an oblique direction to form a second vortex air flow in the second cyclone cylinder (40). Therefore, even in the second cyclone cylinder 40, fine dust contained in the air is separated from the air by the centrifugal force action and falls. The swirling airflow descending from the inside of the second cyclone cylinder 40 is reversed and ascended at the bottom thereof, and the rising airflow reaches the space formed between the air outlet pipe 25 and the backflow preventing rod 51. Due to the difference in air pressure formed according to the flow rate difference between the upper portion and the lower portion, it is sucked straight into the air outlet pipe 25 and discharged to the outside.

On the other hand, the reverse flow prevention rod 51 formed in the lower door 50 is to prevent the reverse flow of the collected fine dust, because the light air coming to the center of the second cyclone barrel 40 immediately rises, The flow of collected fine dust can be minimized. In addition, even if some of the collected fine dust flows backward, it is blocked by the auxiliary ribs 53 provided at the upper end of the non-return bar 51, so that it cannot fall back and fall again. Here, since the auxiliary ribs 53 are formed to be inclined downward, it is possible to more effectively block the fine dust flowing back.

Lastly, in order to separate the wastes collected in the first cyclone barrel 30 and the second cyclone cylinder 40 from the dust collecting apparatus as described above, the lower door 50 may be opened to discard the waste collected therein. have. In the present embodiment, since the lower door 50 is simply attached to the first cyclone cylinder 30 by screwing, opening and closing is easy.

As the lower door 60 is hinged to the first cyclone barrel 30, the backflow prevention rod 55 is supported on the bottom of the second cyclone cylinder 40 by a plurality of ribs 45.

The other side of the lower door 60 is provided with locking / release means for selective locking and releasing.

The locking / release means may include a locking groove 61 formed in the lower door 60 and a locking rod movably installed on the handle 31 of the first cyclone cylinder 30 so as to correspond to the locking groove 61. (71), the first pressing member 72 for pressing the locking rod 71 in the direction in which the locking groove 71 is coupled, and the locking rod 71 by the external force of the first pressing member 72 It is provided with a release unit 73 which overcomes the elastic force and pulls it out of the locking groove 61. Here, the first pressing member 72 is preferably a coil spring coupled to the locking rod 71 to elastically press the locking rod 71 toward the locking groove 61 side.

The release unit 73 is a release button 74 which is installed in and out of one side of the handle 31, the second pressing member 75 for pressing the release button 74 to the outside, and one end locking A wire 76 connected to the rod 71 and a rotation member 77 rotatably installed inside the handle 31 are provided. The second pressing member 75 is a coil spring coupled to the release button 74, and elastically presses the release button 74 to the outside. The wire 76 may preferably be, for example, a rubber band or a long coil spring having elastic force. One end of the wire 76 is connected to the locking rod 71 and the other end is connected to one end of the rotation member 77. The pivot member 77 is connected to the wire 76 at one end of the pivot center and is selectively contactable with the release button 74 at the other end. To this end, the pivot member 77 is rotatably installed in the central portion in the longitudinal direction of the handle 31.

Referring to the operation of the dust collecting apparatus of the upright type vacuum cleaner according to another embodiment of the present invention having the above configuration is as follows.

In order to open and close the lower door 60 to remove dirt collected in the dust collector, the release button 74 is pressed by hand. Then, the release button 74 is pressed into the handle 31 to press the other end of the rotating member 77. Therefore, the other end of the rotation member 77 is rotated by pressing downward, and accordingly, the other end of the rotation member 77 is rotated while going up in the A direction. At this time, the wire 76 is elastically deformed to pull the locking rod (71). The locking rod 71 is then drawn away from the locking groove 61 by the wire 6. As a result, the lower door 60 rotates about the hinge H by its own weight to open the lower opening of the first cyclone barrel 30 as shown.

According to the upright type vacuum cleaner according to the present invention as described above, the dirt can be effectively collected by preventing the backflow of the dirt collected in the dust collector. In addition, by simply opening the lower door by using the locking / unlocking means, the collected dirt can be easily discarded, so that it can be conveniently used.
