Here, the first cover 152 may be larger than the second cover 154. When the dust cover 150 covers the dust collecting body 110, the covers 152 and 154 shield the dust collecting body 110 and the second dust storing part 111 at the same time. That is, the second cover 154 covers the upper side of the second dust storage part 111, and the first cover 152 covers the entire upper side of the dust collection body 110.

The second dust storage portion 111 and the first dust storage portion 112 can be completely shut off by the above-described structure.

The dust collecting cover 150 is provided with a first discharging portion 157 and a second discharging portion 158 for allowing the air introduced into the first dust storing portion 112 to be sucked into the dust separating portion 70, A dust inlet portion 156 for allowing the foreign matter separated and discharged from the cyclone portion 71 to flow into the second dust storage portion 111 and a hinge portion (160).

The discharge units 157 and 158 communicate with the air suction units 72 and 74 of the dust separation unit 70 while the dust collection unit 100 is mounted on the cleaner body 10. That is, the first discharge portion 157 is formed at a position corresponding to the first air suction portion 72 and the second discharge portion 158 corresponds to the second air suction portion 74.

On the other hand, the outer wall of the first dust storage part 112 is symmetrically symmetrical. The outer wall from the air inflow hole 113 to the discharge portions 157 and 158 may be a branch that branches the air to the plurality of air intake portions 72 and 74.

The dust cover 150 is provided with a foreign matter catching part 159 for filtering foreign matters having a large volume of air flowing into the first dust storing part 112 from being sucked into the air suction parts 72 and 74, Is provided.

As a result, the dust collecting apparatus 100 is additionally provided with a separating function for separating foreign matter before the air is sucked into the dust separating unit 70 by the foreign-matter catching 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.

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

First, when air flows in through the air inlet 30 from the surface to be cleaned, the air passes through a connection pipe (not shown) inside the main body 10, As shown in FIG.

The air is branched into the first discharge portion 157 and the second discharge portion 158 and flows through the dust separator (not shown) through the first air suction portion 72 and the second air suction portion 74, 70).

That is, according to the dust collecting apparatus 100 according to the embodiment of the present invention, the first dust storage unit 112 functions as a branching unit for branching the air toward the plurality of air suction units 72 and 74 do. Accordingly, the main body 10 does not need a separate branch portion in order to allow air to be sucked into the plurality of air suction portions 72 and 74. As a result, there is an advantage that the structure of the cleaner main body 10 can be simplified.

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 second dust storage 111.

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

FIG. 6 is a cross-sectional view taken along line I-I 'of FIG. 3, and FIG. 7 is a cross-sectional view of the dust collecting device in a state in which the opening and closing member is rotated according to the embodiment of the present invention.

6 and 7, in the first dust storage part 112 according to the embodiment of the present invention, when the dust collecting device 100 is mounted on the cleaner main body 10, the air inflow hole 113 And an opening and closing part 170 for blocking the air inflow hole 113 when the dust collecting device 100 is separated from the cleaner main body 10.

The opening and closing member 171 is provided on the outer periphery of the opening and closing member 171 and the opening and closing member 171 is provided in the first dust storing unit 112. [ (Not shown).

At least a part of the engaging member 172 is formed with a connecting portion 173 in which the opening and closing member 171 is connected to the engaging member 172. That is, the opening / closing member 171 is connected to the coupling member 172 by the coupling portion 173, and may be rotated about the coupling portion 173.

In other words, at least a part of the opening / closing member 171 may be seen to extend from the engaging member 172. The opening and closing member 171 may be made of an elastic member having a predetermined elastic force.

The opening and closing member 171 and the engaging member 172 may be integrally formed as a single member. That is, the engaging member 172 may be a part of the opening and closing member 171.

The air inlet hole 113 is formed with a coupling protrusion 115 to be inserted into the coupling member 172 so that the opening and closing member 171 is connected to the first dust storage unit 112. That is, the coupling protrusion 115 may be a protrusion formed on the inner circumferential surface of the air inlet hole 113, as the shape of the air inlet hole 113.

That is, the coupling member 172 is fixed to the first dust storage portion 112 by the coupling protrusion 115. Needless to say, unlike the illustrated embodiment, the engaging member 172 may be inserted into the engaging projection 115.

A pressing member 62 for pressing the opening and closing member 171 to rotate the dust collecting apparatus 100 in the process of mounting the dust collecting apparatus 100 on the mounting unit 50 is installed in the connecting pipe 80 inside the cleaner body 10. [ Is provided. Here, the pressing member 62 may be coupled to the inner side of the connection pipe 80 by adhesion or the like.

Hereinafter, the operation of the opening / closing member 171 will be described when the dust collecting apparatus 100 is mounted on the mounting portion 50 or separated from the mounting portion 50.

The air inlet hole 113 of the dust collecting apparatus 100 is positioned above the discharge hole 60 of the main body 10 when the dust collecting apparatus 100 is mounted on the mounting portion 50. [

Then, the dust-collecting apparatus 100 is pressed downward so that the dust-collecting apparatus 100 is mounted on the mounting section 50. Then, the pressing member 62 contacts the lower surface of the opening / closing member 171 to press the opening / closing member 171 upward.

The opening / closing member 171 is rotated about the connecting portion 173, and the air inlet hole 113 is opened.

Accordingly, the discharge hole 60 of the main body 10 can communicate with the air inlet hole 113 of the dust collecting apparatus 100. The air introduced into the main body 10 may be introduced into the first dust storage part 112 through the air inflow hole 113.

Further, in the process of operating the vacuum cleaner, the opening / closing member 171 maintains the state that the air inlet hole 113 is opened, so that the air flow can be smoothly performed.

Next, when separating the dust collecting apparatus 100 from the mounting portion 50, when the dust collecting apparatus 100 is lifted, the air inlet hole 113 is separated from the exhaust hole 60.

Since the pressing member 62 is also separated from the opening / closing member 171, the pressing force by the pressing member 62 is released from the opening / closing member 171. Then, the opening / closing member 171 is rotated about the connecting portion 173 by the restoring force to cover the air inlet hole 113. [ It is a matter of course that the discharge hole 60 is shielded as the air inlet hole 113 is shielded.

According to the above structure, when the dust collecting apparatus is mounted on the cleaner main body or separated from the cleaner main body, the air inflow hole of the dust collecting apparatus can be shielded without any operation.

Accordingly, it is possible to prevent a foreign matter stored in the dust collecting device from flowing out to the outside during the attaching / detaching of the dust collecting device, thereby providing a sanitary cleaning environment.
