An embodiment of the present invention relates to a dust collecting apparatus for a vacuum cleaner.

Generally, a vacuum cleaner sucks air containing foreign matter by using a suction force generated by a suction motor mounted inside the main body, and then filters the foreign matter inside the main body.

Meanwhile, when the suction motor is driven, the air sucked into the cleaner main body is moved to a dust separator for separating foreign matters in the air. The dust separated in the dust separating unit is discharged to the dust collecting apparatus, and the separated dust is discharged to the outside through a predetermined flow path.

In addition, a predetermined flow path or branch flow path for moving the sucked air to the dust separating section may be provided inside the cleaner main body. Then, the air containing the foreign matter is moved into the dust separating portion through the flow path, and dust in the air is filtered.

However, in the related art, when foreign matter, particularly bulky foreign matter, is contained in the air to be sucked, there is a problem that the foreign matter is caught by the flow path or the branch flow path, and the flow of air is not smooth.

In addition, when a bulky foreign object is introduced into the dust separating portion, the foreign object blocks the filter portion provided in the dust separating portion, and foreign matters having small volume such as dust are not separated well Respectively.

As a result, there has been a problem that the dust separating performance of the dust separating portion is entirely deteriorated.

Both side portions of the foreign material separating portion 159 have a shape protruding downward from the center portion of the foreign material separating portion 159.

However, if the foreign object can be separated before the bulky foreign object is moved to the first discharge portion 157 and the second discharge portion 158, the shape of the foreign material separating portion 159 is only one embodiment, The separator 159 is not limited to the above embodiment.

As a result, the dust collecting apparatus 100 may be provided with a separating function for separating foreign matter before the air is sucked into the dust separating unit 70 by the foreign material separating unit 159. Also, since the bulky foreign matter does not flow into the dust separating unit 70, the dust separating performance of the dust separating unit 70 is improved.

Referring to FIG. 7, the air flowing into the flow guide part 112 through the air inlet hole 113 is branched and moved to the plurality of outlet parts 157 (solid line). In this process, the bulky foreign matter is separated by the foreign material separating portion 159 and is not moved to the discharge portions 157 and 158, but remains in the flow guide portion 112 (dotted line).

Hereinafter, the air flow in the dust collecting apparatus 100 will be briefly described.

First, when air is sucked from the surface to be cleaned by the suction force of the suction motor provided in the cleaner main body 10 through the air inlet 30, air flows through a connecting tube (not shown) And flows into the flow guide part 112 through the air inlet hole 113.

The air is branched into the first discharge portion 157 and the second discharge portion 158 and passes through the first air intake portion 72 and the second air intake portion 74, (Not shown).

In this case, a bulky foreign object contained in the air is caught by the foreign material separating unit 159, so that it is restricted from moving to the plurality of discharging units 157 and 158. Accordingly, foreign matter having a large volume such as dust is sucked and filtered through the dust separating unit 70 without being filtered.

That is, according to the dust collecting apparatus 100 according to the embodiment of the present invention, the flow guide portion 112 functions as a branching portion for branching the air toward the plurality of air suction portions 72 and 74, Dust separation function can be performed. As a result, the dust separating unit 70 has an advantage that dust separation performance can be improved since the primary separated air is filtered again.

Thereafter, the air sucked into the dust separating unit 70 is separated and discharged through an air discharging unit (not shown), and the separated dust is introduced into the dust collecting apparatus 100 through the dust introducing unit 156, That is, into the dust storage 111. [

The dust introduced into the dust storage part 111 may be compressed in the direction adjacent to the fixing member 124 by the rotating member 126.

Hereinafter, the structure of a dust collecting apparatus according to another embodiment of the present invention will be described. However, the present embodiment differs from the first embodiment only in the shape of the separating portion, so that the difference will be mainly described, and the description of the first embodiment and the reference numerals will be used for the same portions except for the first embodiment.

FIG. 8 is a perspective view showing the structure of a dust collecting cover according to a second embodiment of the present invention, and FIG. 9 is a sectional view showing the flow of air according to the second embodiment of the present invention.

8 and 9, in the dust-collecting cover 250 according to the second embodiment of the present invention, the air introduced into the auxiliary storage unit 212 is branched into the plurality of air-suction units 72 and 74 A dust inlet 256 for allowing the dust discharged from the dust discharger 76 to flow into the dust collecting apparatus and an auxiliary storage unit 256 for discharging the dust discharged from the dust discharger 76, A first engaging member 259 and a second engaging member 260 for filtering a large foreign matter in the air introduced into the air passage.

In detail, the plurality of latching members 259 and 260 are provided on one side of the plurality of discharge portions 257 and 258, respectively. The plurality of latching members 259 and 260 are positioned such that one surface thereof is adhered to the dust cover 250 and extends downward from the adhering surface. That is, the latching members 259 and 260 are positioned to protrude toward the storage space of the auxiliary storage unit 212.

Flow grooves 259a and 260a curved upward are formed on the respective engaging members 259 and 260 so that foreign objects such as dust are not filtered by the engaging members 259 and 260.

Accordingly, the bulky foreign matter in the air flowing through the air inflow hole 213 is filtered by the plurality of latching members 259 and 260 (dotted line), but foreign matter having a small volume such as dust is discharged to the latching members 259 and 260, And can be moved to the discharge portions 257 and 258 (solid line) without being filtered.

As a result, as described in the first embodiment, foreign matter having a large volume of air is not sucked into the dust separating unit 70 but remains in the auxiliary storage unit 212. Therefore, the problem that the flow path is blocked by the large foreign matter or the air flow is not smooth can be solved. The user may remove the dust stored in the auxiliary storage unit 212 by separating the dust cover 250.

In addition, since the dust separating unit 70 filters small foreign matter such as dust in the primarily filtered air, the dust separating performance can be improved.

However, the shape of the engaging member for filtering the foreign object is not limited to the above, and can be variously modified within the scope consistent with the spirit of the present embodiment. In addition, three or more of the latching members may be provided, as shown in the drawings.

In addition, the latching members 259 and 260 are not necessarily provided in the dust cover 250, and may be coupled to the auxiliary storage unit 212.
