When the first suction member 340 is rotated from the receiving area 330 and is located at one side of the main body case 310, the female first male Velcro tape 410 is attached, 340 are fixed to the first side portions 310a of the main body case 310. [

The second Velcro tape 420 is attached to the second side surface 310b of the main body case 310 and the second side surface 310b of the main body case 310 when the second suction member 350 is rotated from the receiving area 330 and is located outside the receiving area 330 And is provided on the surface opposite to the second side surface portion 310b. When the second suction member 350 is rotated from the receiving area 330 and is located at one side of the main body case 310, the second male and female Velcro tapes 420 are attached, 350 are fixed to the second side surface portion 310b of the main body case 310.

The suction force for sucking dirt is generated through the suction motor installed in the cleaner main body 100 and the cleaner main body 100 is connected to the main body case 310 through the extension passage 200. Therefore, The first suction member 340 and the second suction member 350 should be connected to the body case 310 in order to supply a suction force for sucking dirt to the first suction member 340 and the second suction member 350.

And includes a connecting member as a structure for connecting the first suction member 340 and the second suction member 350 to the body case 310. The connecting member includes a first bulging tube 510 and a second bulging tube 520.

A first end portion 520a of the second bellows pipe 520 is inserted into the second guide portion 372.

Hereinafter, the use of the vacuum cleaner according to one embodiment of the present invention will be described.

The first suction member 340 and the second suction member 350 may be connected to the receiving area 330 of the main body case 310 in accordance with the user's selection, in order to perform cleaning using the vacuum cleaner according to one embodiment of the present invention. Or the first suction member 340 and the second suction member 350 are rotated from the receiving area 330 of the main body case 310 and are used in a state in which the first suction member 340 and the second suction member 350 are unfolded.

When the first suction member 340 and the second suction member 350 are to be used in a state where they are located in the receiving area 330 of the main body case 310, the first suction member 340 is inserted into the first fixing protrusion 343 And the second suction member 350 is fixed in a state of being coupled to the second fixing hole 330d while the second suction member 350 is fixed in a state of being coupled to the first fixing hole 330c, The suction member 340 and the second suction member 350 are used in a fixed state in the receiving area 330 without shaking. Therefore, the first suction member 340 and the second suction member 350 are not separated from the receiving area 330 in the process of sucking dirt such as dust on the cleaning surface while sliding the dust-collecting device 300 on the surface to be cleaned.

When the first suction member 340 and the second suction member 350 are positioned in the receiving area 330, the first dust suction port 320 formed on the bottom surface of the main body case 310 is connected to the first suction member The second dust suction port 341 and the third dust suction port 351 located in front of the first suction member 340 and the second suction member 350 and formed in the first suction member 340 and the second suction member 350, And is positioned behind the dust inlet 320. That is, the first dust inlet 320, the second dust inlet 341, and the third dust inlet 351 are arranged in two rows.

In this state, the first dust suction port 320, the second dust suction port 341, and the third dust suction port 351 simultaneously suck dirt when sucking dirt such as dust on the surface to be cleaned. The first dust suction port 320 sucks dirt on the surface to be cleaned and then the second dust suction port 341 and the third dust suction port 351 in the region where the first dust suction port 320 sucks the dirt, The dust on the surface to be cleaned can be further sucked. In this case, the dirt which can not be sucked in through the first dust inlet 320 can be sucked through the second dust inlet 341 and the third dust inlet 351, so that even the dirt on the surface to be cleaned, So that the cleaning efficiency can be increased.

FIGS. 3 and 4 are a perspective view and a bottom view showing a state in which the first suction member and the second suction member shown in FIG. 2 are unfolded.

3 and 4, when the user rotates the first suction member 340 and the second suction member 350 from the receiving area 330 and uses the first suction member 340 and the second suction member 350 in a unfolded state, The first fixing protrusion 343 of the first suction member 340 and the second fixing protrusion 353 of the second suction member 350 can be moved in the same direction as the first and second suction members 350 and 350, And is separated from the first fixing hole 330c and the second fixing hole 330d. When the user then rotates the first suction member 340 and the second suction member 350 toward the outside of the receiving area 330, the first suction member 340 moves to the first side part 310a of the main body case 310 And the second suction member 350 is rotated toward the second side surface portion 310b of the main body case 310. [ At this time, the first end portions 510a and 520a of the first bellows pipe 510 and the second bellows pipe 520 are pulled along the first suction member 340 and the second suction member 350, And the second end portions 510b and 520b of the second bellows pipe 520 are pulled while being guided by the first guide portion 371 and the second guide portion 372 in the body case 310. In this process, 1 The corrugated tube 510 and the second corrugated tube 520 are pulled. The first suction member 340 and the second suction member 350 are connected to the main body case 310 by the first corrugated pipe 510 and the second corrugated pipe 520 so that the first suction member 340, And the second suction member 350 are also provided with a suction force.

In this state, the first suction member 340 and the first and second Velcro tapes 410 attached to the first side portions 310a of the main body case 310 are attached to fix the first suction member 340 The second suction member 350 and the second Velcro tape 420 mounted on the second side surface portion 310b of the main body case 310 are attached to fix the second suction member 350. [

When the first suction member 340 and the second suction member 350 are unfolded as described above, the second dust suction port 341 and the third dust suction port 351 are positioned on the left and right sides of the first dust suction port 320 do. That is, the first dust suction port 320, the second dust suction port 341, and the third dust suction port 351 are arranged in one line. In this case, the first dust suction port 320, the second dust suction port 341 and the third dust suction port 351 are located on the cleaning surface in a long length. When the dust suction device 320 is cleaned in this state, When sliding on the cleaning surface one time, it is possible to suck the dirt which is larger than usual. Accordingly, the number of processes of sucking dirt while sliding the dust collecting apparatus 300 on the surface to be cleaned is reduced, thereby reducing the cleaning time and increasing the cleaning efficiency.

The first suction member 340 and the second suction member 350 are positioned lower than the height of the main body case 310 in a state in which the first suction member 340 and the second suction member 350 are unfolded. According to this, the first suction member 340 and the second suction member 350 are inserted into the narrow space, for example, between the cleaning surface and the lower end of the furniture, in which the body case 310 is hard to be inserted, This is possible. Therefore, cleaning of a narrow space becomes easy.

By using the vacuum cleaner according to one embodiment of the present invention, the cleaning efficiency can be improved by shortening the cleaning time, reliably removing dirt, and easily cleaning a narrow space.

The description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the scope of the invention. Thus, the present invention should not be construed as limited to the embodiments set forth herein but is to be accorded the widest scope consistent with the principles and novel features set forth herein.
