In the present invention, the primary dust separation unit and the secondary dust separation unit, each of the primary cyclone unit 214 and a plurality of small secondary cyclone unit 215 for separating foreign matter in a cyclone method It is composed.

In more detail, the primary cyclone portion 214 has a cylindrical container shape of which the lower end is opened, and a first suction port 214a communicating with the hose connecting portion 210 is formed at an upper side of the primary cyclone portion 214. The first exhaust port 214b penetrated in the vertical direction is formed at the ceiling center portion of the cyclone portion 214.

Here, the first suction port 214a guides the contaminated air introduced from the outside in the tangential direction of the primary cyclone part so that air introduced into the first suction port 214a is in the primary cyclone part 214. It is configured to allow spiral flow along the inner wall.

In addition, on the upper portion of the primary cyclone portion 214, the small secondary cyclone portions 215 formed integrally with the outer wall of the dust collecting container 210 are circumferentially arranged around the upper portion of the primary cyclone portion. It is arranged in the direction, the upper end of each of the secondary cyclone portion 215 is formed to protrude a predetermined height from the upper end of the primary cyclone portion 214.

On the other hand, a part of the side surface of each of the secondary cyclone portion 215 protruding above the upper end of the primary cyclone portion 214 is cut in the vertical direction, the second suction in communication with the first exhaust port 214b Spheres (not shown) are formed, and upper ends of the respective secondary cyclone portions 215 are opened to form a second exhaust port (not shown).

In addition, a lower portion of the secondary cyclone portion 215 is formed with a cone portion 215a, the diameter of which decreases toward the lower side, and foreign substances such as dust may be discharged from the lower end of the secondary cyclone portion 215. The foreign matter discharge port 215b penetrated up and down is formed.

Here, the adjacent secondary cyclone portions 215 are integrally formed to be in contact with each other, so that air does not flow between the secondary cyclone portions 215.

In addition, the dust collecting container cover 220 is mounted on the secondary cyclone portions 215.

Third exhaust ports 221 respectively corresponding to the second exhaust ports of the respective secondary cyclone portions are formed in the edge portion of the dust collecting container cover 220 in the vertical direction.

Next, the upper cover 230 of which the lower end is opened is detachably mounted on the upper part of the dust container cover 220.

To this end, three locking protrusions (not shown) are formed on an outer circumferential surface of the dust container cover 220, and three locking grooves (not shown) are inserted and locked on the inner circumferential surface of the upper cover 230. Are formed.

As described above, the hinge connection portion 240 is configured to protrude to the side of the dust collecting container 210, the hinge connection portion 240 is configured in a state that does not protrude from the side of the dust collecting container 210. In this case, the dust collecting capacity of the dust collecting container 210 is reduced by the volume of the hinge connection part 240.

In addition, a first inclined surface 242a that is inclined at a predetermined angle is formed under the second connecting portion 242.

Here, the first inclined surface 242a is, in the process of the dust collector 200 is mounted downward from the upper portion of the cleaner body 100 to the dust container mounting portion 130, the dust collector 200, in particular The hinge connection part 240 prevents an obstacle in mounting the dust collector 200 such as being damaged by being hit by an edge of the dust container mounting part 130 or being caught by an edge of the cleaner body 100.

In more detail, the first inclined surface 242a has a lower edge and an upper edge parallel to the hinge axis, and a lower edge of the first inclined surface 242a is formed at the bottom of the second connecting portion 242. The outer edge of the bottom of the second connection portion 242 is formed.

Of course, the entire bottom of the second connecting portion 242 may be formed to be inclined upwardly outward to form the first inclined surface, and the first inclined surface 242a may be configured as a curved surface rather than a plane.

By the above configuration, in the process of mounting the dust collecting device 200 to the dust collecting container mounting unit 130, the hinge connection portion 240 protruding to the outside of the dust collecting container 210 is the dust collecting container mounting unit 130. Even if it hits the upper edge of the) is smoothly slipped by the first inclined surface (242a) without mounting. Furthermore, the impact is dispersed when the hinge connector 240 hits one side of the dust collecting container mounting unit 130 to prevent the hinge connector 240 from being damaged.

In addition, a fixing device 250 for fixing the lower panel 211 is provided on the opposite side of the hinge connector 240.

The fixing device 250, the lever receiving portion 251 is provided on the outer surface of the dust collecting container 210, and the lever receiving portion 521 is rotatably connected to the inside of the lever receiving portion 251. It is configured to include a lever 252 accommodated in.
