The cover 120 and a storage device 150 coupled to the lower side of the handle body 110 to store the foreign matter filtered in the handle body 110 can be stored.

In detail, a coupling part 112 for coupling the storage device 150 to the lower side of the handle body 110 is formed. The coupling part 112 extends downward from the handle body 110. In addition, a coupling hole 113 is formed in the coupling part 112. In addition, the storage device 150 has a locking protrusion 312 to be inserted into the coupling hole 113. In contrast, the storage device 150 may be rotatably coupled to the handle body 110. That is, one side of the storage device 150 may be coupled to the coupling part 112 by a hinge, and the other side thereof may be detachably coupled to the coupling part 112.

The separation unit 130 is formed inside the handle body 110 to catch the foreign material. In addition, a first opening 114 is formed at the lower side of the handle body 110 to allow foreign substances caught in the separation unit 130 to be discharged from the handle body 110 to the storage device 150.

In addition, a second opening 116 is formed below the handle body 110. The second opening 116 is formed at the rear side of the first opening 114 based on the flow direction of air. In addition, the storage device 150 simultaneously shields the first opening 114 and the second opening 116 while being coupled to the handle body 110.

In addition, the second opening 116 allows the flow of air to occur in the storage device 150. That is, some of the air sucked through the suction nozzle 30 is introduced into the storage device 150 through the first opening 114, and the air introduced into the storage device 150 is the second opening. It is discharged to the handle body 110 through 150.

Therefore, the first flow path 142 after being branched from the first flow path 142 and the first flow path 142 by the first opening 114 and the second opening 116. ) And the second flow path 144 to be combined again.

In addition, the first flow path 142 is defined as an inner space of the handle body 110, and the second flow path 144 is defined by the first opening 114 and the inner space of the storage device 150. Is defined.

In detail, the separation unit 130 is located at a portion where the second flow passage 142 is branched from the first flow passage 142. In addition, the separating unit 110 to take a large foreign material moving along the first flow path 142, and guides the caught foreign material to move to the second flow path (144).

The separation unit 130 is formed in a plate shape. In addition, it extends vertically downward from the inner upper surface of the handle body (110). The lower end of the separation unit 130 extends to a position adjacent to the first opening 142. In addition, the separation unit 130 is formed in a direction parallel to the flow direction of air.

In addition, the separating part 130 may be integrally formed with the handle body 110 or may be coupled to the handle body 110. 2 shows that the separating part 130 is integrally formed with the handle body 110.

Here, when the separation unit 130 is coupled to the handle body 110, a fitting groove having a shape corresponding to the upper side of the separation unit 130 is formed in the handle body 110, the separation unit 130 may be fitted to the fitting groove.

Alternatively, the guide ribs are protruded to both sides on the upper side of the separation unit 130, and the coupling rib to which the guide rib is coupled to the handle body 110 is formed, so that the separation unit 130 is coupled to the It may be possible to engage the rib in a sliding manner. In this case, the coupling ribs may have a cross section having an “L” shape.

In addition, the front portion 131 of the separation unit 130 is formed to be inclined toward the rear portion 132 from the upper side to the lower side based on the air flow direction. That is, the front portion 131 is inclined in a direction closer to the rear portion 132. Therefore, the width of the separation unit 130 becomes smaller from the upper side to the lower side.

As described above, when the front portion 131 of the separating portion 130 is formed to be inclined toward the rear portion 132 as it goes from the upper side to the lower side, a large foreign material such as a tissue is lowered in the state caught by the separating portion 130. Can be easily dropped.

Hereinafter, the operation of the vacuum cleaner according to the present embodiment will be described.

The suction motor provided in the cleaner body is operated to suck air containing foreign matter on the surface to be cleaned through the suction nozzle 30. Air containing foreign matter sucked through the suction nozzle is moved to the handle 100 along the extension pipe 40.

In addition, most of the air including the foreign matter moved to the handle 100 flows through the first flow path 142, and a part of the air passes through the second flow path 144. Accordingly, it may be understood that the first flow passage 142 serves as a main flow passage, and the second flow passage 144 serves as a bypass flow passage bypassed from the main flow passage 142.

In detail, a large foreign material in the air flowing through the first flow path 142 is caught by the separation unit 130. In addition, the foreign matter caught in the separating part 130 is dropped downward due to the inclination of the front part 131 of the separating part 130 and moved to the second flow path 144. That is, the foreign matter caught in the separator 130 is stored in the storage device 150. At this time, the foreign matter caught in the separator 130 may be moved to the storage device 150 more easily by the air moving to the second flow path 144.

In addition, the air flowing into the second flow passage 144 flows into the first flow passage 142 through the second opening 116. At this time, small foreign matter on the second flow path 144 flows into the first flow path 142 through the second opening 116. Here, since the second opening 116 allows the second flow passage 144 to be connected to the first flow passage 142, the second opening 116 may be referred to as a "connection flow passage".

In addition, the large foreign matter dropped into the storage device 150 by the air flowing through the second flow path 144 is sequentially accumulated in the second opening 116. Here, since the storage device 150 forms a part of the second flow path 144, the foreign matter caught in the separator 130 may be described as being stored in the second flow path 144.

Then, the air passing through the handle 100 flows into the cleaner body through the connection hose 60. In addition, the air introduced into the cleaner body 10 is introduced into the dust collecting device 20 and undergoes a foreign matter separation process. Then, the foreign matter separated from the air is stored in the dust collector 20, the air is moved back to the cleaner body 10, and finally discharged from the cleaner body 10 to the outside.

According to the present embodiment as described above, since the large foreign material is caught in the separating unit 130 inside the handle 10 before being moved to the dust collecting device 20, and stored separately in the storage device 150, such foreign matter is collected. It is introduced into the device 20 it is possible to prevent the dust collector 20 is blocked.

In addition, as the flow path (second flow path) is formed to allow the air moved to the storage device 150 to be re-introduced into the handle body 110, foreign matter caught in the separation unit 130 is more easily stored in the storage device. There is an advantage to move to 150.

Among the air containing the foreign matter introduced into the handle body 210 by the above configuration, some air and foreign matter having a small weight move along the first flow path 212, and other foreign matter and a large foreign matter are It is branched from the first flow path while the inertia force is maintained and moves along the second flow path 214. In addition, air and foreign matter moving along the second flow path may meet the blocking wall 223. Therefore, foreign matters having a large weight in the air are separated from the inside of the handle body 210 by inertia. Then, the separated large foreign matter is sequentially stacked from the blocking wall 223. That is, the separated foreign matter is stored in the second flow path 214.

In addition, the air flowing along the second flow path 214 and hitting the blocking wall 223 is switched by the blocking wall 223 so that the air flows through the connecting flow path 216 again. 212).
