8, the operation of the grill assembly 200 will be described.

The grill assembly 200 is provided such that the grill 210 and the rotating body 220 are rotatable and dust and foreign substances on the surface of the grill 210 are separated by centrifugal force.

When the suction force is generated by the motor 120, the rotating body 220 and the grill 210 can rotate integrally. The air primarily filtered by the swirling airflow of the cyclone chamber 170 forms a main flow path 260 through the grill 210 and flows toward the outflow pipe 173 side. The main flow channel 260 may be formed from the upper side to the lower side so that air introduced through the grille 210 and discharged into the outlet pipe 173 side.

An air flow having a direction opposite to the direction of the main flow path 260 may be formed between the second fan 222 and the case 240 of the rotating body 220 by the second fan 222. The second fan 222 of the rotating body 220 on which the grille 210 is mounted and the case 240 are provided between the second fan 222 and the case 240 so as to prevent airflow caused by the suction force of the motor 120, An airflow having an opposite direction to the direction of the airflow can be formed.

A plurality of openings 244 formed in the case 240 are provided to allow the outside air to flow between the second fan 222 and the case 240. The outside air flowing into the space between the second fan 222 and the case 240 is discharged through the dust removing channel 270 to remove dust and hair from the dust removing channel 270 or the grill 210 .

The dust removed from the grill 210 to the dust removing passage 270 may be collected by the dust collecting chamber 180 while being rotated by the circulating airflow of the cyclone chamber 170.

In this way, by applying the rotatable grill 210 to the cyclone dust collecting apparatus 140, the suction force of the handy-type vacuum cleaner 100 to the handy-stick vacuum cleaner 1 can be prevented from being lowered, have. In addition, since dust can be prevented from sticking to the surface of the grill 210, it is easy to remove dust in the cyclone dust collector 140. That is, after the cyclone dust collector 140 is separated from the handy main body 110, the user only needs to remove the dust collected in the dust collection chamber 180 by separating the outer casing 144 and the inner casing 143, The cyclone dust collecting apparatus 140 can be easily and easily cleaned.

FIG. 9 is a cross-sectional view of the cyclone dust collecting apparatus of FIG. 4 taken along line I-I ', and FIG. 10 is a sectional view of a handy-type vacuum cleaner of a handy-stick type vacuum cleaner according to an embodiment of the present invention. 10 is a sectional view schematically showing the handy type vacuum cleaner 100. As shown in FIG. In Fig. 9, solid lines indicate movement of dust, and dotted lines indicate movement of air from which dust has been removed.

As shown in FIGS. 9 and 10, when the motor 120 is driven, the contaminated air on the surface to be cleaned can be introduced into the suction duct 150 by the suction force generated by the driving of the motor 120.

The air introduced into the suction duct 150 is guided to the cyclone chamber 170. The air guided to the cyclone chamber 170 is swirled by the spiral portion 172 inside the cyclone chamber 170.

Dust having a heavier weight than air is scattered radially outward by the centrifugal force and flows into the dust collection chamber 180 through the dust outlet 191 located above the cyclone chamber 170. At this time, the dust can smoothly flow into the dust collection chamber 180 along the guide 145. The dust introduced into the dust collection chamber 180 can be dropped by gravity and collected in the dust collection chamber 180.

The dust, which has been primarily removed by the centrifugal force in the cyclone chamber 170, may be secondarily filtered by a certain amount of dust while passing through the grill assembly 200.

Air passing through the grill assembly 200 may flow through the outlet tube 173. The air flowing along the outlet pipe 173 is discharged to the outside of the cyclone dust collecting apparatus 140 through the discharge port 142 of the cyclone dust collecting apparatus 140 and flows into the air inlet 117 of the handy main body 110. The air introduced into the air suction port 117 is discharged to the outside of the handy type vacuum cleaner 100 through the filter 130 and the motor 120 in order.

The air in which the dust is primarily removed by the centrifugal force in the cyclone chamber 170 is introduced into the plurality of openings 211 of the grill assembly 200 with the rotational force appropriately controlled by the protruding ribs 147 do. The air introduced into the plurality of openings 211 of the grill 210 may rotate the first fan 221 of the grill assembly 200. It is possible to prevent dust from sticking to the grill 210 by the rotation of the first fan 221.

At this time, the rotation of the first fan 221 causes the second fan 222 to generate airflow in the direction opposite to the suction direction, pushing the air introduced into the dust removal flow path 270 in the direction opposite to the suction direction Thereby preventing dust from being caught between the entire body 220 and the case 240.

The above-described cyclone dust collecting apparatus 140 can take a lower collecting system in which dust is introduced into the lower part of the handy type vacuum cleaner 100 and is collected in the lower part of the handy type vacuum cleaner 100. That is, the cyclone dust collecting apparatus 140 takes a lower collecting mode in which dust is introduced in the first direction M of the handy vacuum cleaner 100 and is collected in the second direction N opposite to the first direction M . Since the first direction M and the second direction N do not coincide with the rotation axis direction X of the grill 210 when the lower collecting system is adopted as described above, the dust is effectively separated from the air in the cyclone chamber 170 . That is, when the lower collecting system is adopted, the grill assembly 200 may not prevent the dust from separating from the air in the cyclone chamber 170.
