Description

[0001] The present invention relates to a suction device for a vacuum cleaner,

This embodiment relates to a suction device of a vacuum cleaner.

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

The vacuum cleaner includes a suction nozzle for sucking air containing foreign matter, a vacuum cleaner main body communicating with the suction nozzle, an extension pipe for guiding air sucked in the suction nozzle to the vacuum cleaner main body, And a connection pipe connecting the air passing through the extension pipe to the cleaner main body. A dust collecting device for separating foreign matter from the air is installed in the cleaner main body.

The air containing foreign matter sucked through the suction nozzle is sequentially transferred to the dust collecting apparatus through the extension pipe, the handle, and the connection pipe.

However, according to the conventional vacuum cleaner, when a large foreign object such as a toilet paper is sucked by the dust collecting device, the suctioned foreign object is caught by the dust collecting device and blocks the flow path, so that the suction performance may be lowered.

In addition, when relatively large foreign matter is caught by the dust collecting device, the user must remove the foreign object from the dust collecting device after the dust collecting device is separated from the cleaner main body.

The present embodiment has been proposed in order to solve the above-mentioned problems. It is an object of the present invention to provide a suction device for a vacuum cleaner, which allows a large foreign object such as a toilet paper to be filtered before moving to the dust collecting device, And the like.

According to an aspect of the present invention, there is provided a suction device for a vacuum cleaner, comprising: a first flow path formed in a handle capable of being held by a user, A second flow path branched from the first flow path, at least a portion of which is located in the handle; And a connection flow path through which the second flow path is branched from the first flow path and then connected to the first flow path; And the second flow path is configured to communicate with the connection hose connected to the handle by being coupled to the first flow path by the connection flow path.

According to another aspect of the present invention, there is provided a suction device for a vacuum cleaner, comprising: a body through which air containing foreign matter flows; A separator provided on the body to separate foreign matter from the air; And a storage device coupled to the body for storing separated foreign objects, the body having a first opening through which the separated foreign object is discharged to the storage device; And a second opening to allow the storage device and the body to communicate with each other.

According to another aspect of the present invention, there is provided a suction device for a vacuum cleaner, comprising: a body through which air containing foreign matter flows; An opening formed in the body for discharging the dust separated from the body; And a cover selectively shielding the opening. The body includes a first flow path through which air and foreign matter flow, and a second flow path branched from the first flow path, And is communicated.

According to the proposed embodiment, the large foreign object is caught by the separating portion inside the handle before being moved to the dust collecting device, and is stored separately in the storage device, so that foreign matter can be prevented from flowing into the dust collecting device and clogging the dust collecting device .

Further, since the flow path for allowing the air moved to the storage device to be re-introduced into the handle body is formed, the foreign matter caught by the separation portion can be more easily moved to the storage device.

Hereinafter, embodiments will be described in detail with reference to the drawings.

1 is a perspective view of a vacuum cleaner according to a first embodiment of the present invention.

Referring to FIG. 1, the vacuum cleaner 1 according to the present embodiment includes a vacuum cleaner main body 10 having a suction motor (not shown) for generating a suction force therein, And a dust collecting device 20 for separating foreign matter contained in the cleaner main body 10 and being selectively mounted on the cleaner main body 10.

The air containing the foreign object sucked into the suction nozzle 30 is sequentially transferred to the cleaner body 10 through the extension pipe 40, the handle 100 and the connection hose 60 in order. The air sucked into the cleaner main body 10 is moved to the dust collecting apparatus 20 along a connection path (not shown).

The suction device is composed of the suction nozzle 30, the extension pipe 40, the handle 100, and the connection hose 60. However, the configuration of the suction device is not limited to this, 30, the extension pipe 40, the handle 100, and the connecting hose 60, as shown in FIG.

In addition, the suction device is provided with a foreign matter catching structure that allows large foreign matter to be filtered before the suctioned air moves to the dust collecting device (20). Here, since the connecting passage is also provided before the air is introduced into the dust collecting apparatus, a foreign matter trapping structure may be formed in the connecting passage. The above-mentioned foreign matter catching structure will be described later.

The cleaner main body 10 is provided with a pair of moving wheels 11 for moving the cleaner main body 10 and the moving wheels 11 are provided on both sides of the cleaner main body 11. That is, the mobile wheel 11 includes a left wheel and a right wheel. The main body of the cleaner includes a main body handle 13 for allowing the user to hold the main body of the vacuum cleaner.

FIG. 2 is a perspective view of a handle according to the present embodiment, and FIG. 3 is a cross-sectional view taken along line I-I 'of FIG.

2 and 3, the handle 100 according to the present embodiment includes a handle body 110 having an air flow path formed therein, a handle 110 coupled to the handle body 110, A cover 120 and a storage device 150 coupled to a lower side of the handle body 110 to store foreign matters filtered in the handle body 110.

In detail, a coupling portion 112 for coupling the storage device 150 is formed on the lower side of the handle body 110. The engaging portion 112 extends downward from the handle body 110. A coupling hole 113 is formed in the coupling part 112. The storage device 150 is formed with a latching protrusion 312 for insertion into the coupling hole 113. Alternatively, 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 may be detachably coupled to the coupling part 112.

The handle body 110 is formed with a separating part 130 to allow foreign objects to be caught. A first opening 114 is formed in the lower portion of the handle body 110 to allow foreign matter caught by the separating unit 130 to be discharged from the handle body 110 to the storage device 150.

A second opening 116 is formed on the lower side of the handle body 110. The second opening 116 is formed on the rear side of the first opening 114 with reference to the flow direction of the air. The storage device 150 simultaneously shields the first opening 114 and the second opening 116 in a state where the storage device 150 is coupled to the handle body 110.

The second opening 116 allows air to flow in the storage device 150. That is, a part of the air sucked through the suction nozzle 30 flows into the storage device 150 through the first opening 114, and the air introduced into the storage device 150 flows through the second opening And then discharged to the handle body 110 through the opening 150.

The handle 100 is provided with the first flow path 142 and the first flow path 142 after being branched from the first flow path 142 by the first opening 114 and the second opening 116. [ And a second flow path 144 is formed.

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

In detail, the separator 130 is located at a portion where the second flow path 142 branches from the first flow path 142. The separator 110 guides a large foreign object moving along the first flow path 142 and moves the foreign object to the second flow path 144.

The separator 130 is formed in a plate shape. And extends vertically downward from the upper surface of the handle body 110. The lower end of the separator 130 extends to a position adjacent to the first opening 142. The separator 130 is formed in a direction parallel to the flow direction of the air.

The separator 130 may be integrally formed with the handle body 110 or may be coupled to the handle body 110. 2, the separating part 130 is formed integrally with the handle body 110. As shown in FIG.

When the separating part 130 is coupled to the handle body 110, the handle body 110 has a fitting groove having a shape corresponding to the upper side of the separating part 130, (130) can be constrained to the fitting groove.

Alternatively, a guide rib may be formed on both sides of the separating part 130, and a coupling rib may be formed in the handle body 110 to engage with the guide ribs. In this case, So that it can be slidably coupled to the ribs. In this case, the engaging rib may be formed in an L-shaped cross section.

The front part 131 of the separating part 130 is inclined toward the rear part 132 from the upper part to the lower part with respect to the flow direction of the air. That is, the front portion 131 is inclined toward the rear portion 132. Therefore, the width of the separating part 130 decreases from the upper side to the lower side.

When the front part 131 of the separating part 130 is inclined toward the rear part 132 from the upper side to the lower side as described above, when a large foreign object such as a toilet paper is caught by the separating part 130, As shown in Fig.

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

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

Most of the air containing the foreign matter moved by the handle 100 flows through the first flow path 142 and the remaining part of the air passes through the second flow path 144. Therefore, it can be understood that the first flow path 142 functions as a main flow path, and the second flow path 144 functions as a bypass flow path bypassed from the main flow path 142. [

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

The air flowing into the second flow path (144) flows into the first flow path (142) through the second opening (116). At this time, a small foreign object on the second flow path 144 flows into the first flow path 142 through the second opening part 116. [ The second opening 116 may be referred to as a "connecting channel" because the second channel 144 is connected to the first channel 142. [

A large foreign object dropped to the storage device 150 by the air flowing through the second flow path 144 is sequentially accumulated in the second opening part 116. Since the storage device 150 forms a part of the second flow path 144, the foreign matter caught by the separation part 130 may be stored in the second flow path 144.

The air passing through the handle 100 flows into the main body of the cleaner through the connection hose 60. The air introduced into the cleaner main body 10 flows into the dust collecting apparatus 20 and is separated from the dust. The foreign matter separated from the air is stored in the dust collecting apparatus 20, and the air is finally transferred to the cleaner body 10 and finally discharged to the outside from the cleaner body 10. [

According to this embodiment, since a large foreign object is caught by the separating part 130 inside the handle 10 and stored separately in the storage device 150 before the foreign object moves to the dust collecting device 20, It is possible to prevent the dust-collecting apparatus 20 from being clogged by flowing into the apparatus 20.

As the flow path (second flow path) for re-flowing the air moved to the storage device 150 into the handle body 110 is formed, the foreign matter caught by the separation part 130 can be more easily transferred to the storage device 150, (150).

4 is a sectional view showing the internal structure of the handle according to the second embodiment.

The present embodiment is the same as the first embodiment except that there is a difference in structure inside the handle. Therefore, only the characteristic parts of the present embodiment will be described below, and the same contents as those of the first embodiment will be referred to as the first embodiment.

The handle body 210 includes a first flow path 212 communicating with the cleaner main body 10 and a second flow path 212 branched from the first flow path 212, A second flow path 214 in which the inertia force is maintained and a connection flow path 216 in which the first flow path 212 and the second flow path 214 are connected are formed.

A partition 220 separating the first flow path 212 and the second flow path 224 and a blocking wall 223 blocking the second flow path 214 are formed in the handle body 210, .

A lower portion of the handle body 210 is formed with an opening 224 through which foreign matter separated from the handle body 210 can be discharged to the outside. A cover 230 for opening and closing the opening 224 is coupled to the handle body 210. The handle body 210 is formed with an engaging portion 226 for engaging with the cover 230. The cover 230 covers the opening 224 in a state where the cover 230 is coupled to the handle body 210 so that the cover 230 covers a part of the second flow path 214 .

In detail, the cover 230 is rotatably coupled to the coupling portion 226 by a hinge 232 at one side. The other side of the cover 230 is detachably coupled to the engaging part 226. The cover 230 is formed with a coupling protrusion 234 to be coupled to the coupling portion 226 and a protrusion insertion groove 238 into which the coupling protrusion 234 is inserted is formed in the coupling portion 226 .

According to the above-described configuration, the air, some air, and a small amount of foreign matter introduced into the handle body 210 move along the first flow path 212, and a part of the air and the heavy foreign matter And is moved along the second flow path 214 by branching from the first flow path with the inertia force maintained. Air and foreign matter moving along the second flow path are brought into contact with the blocking wall 223. Therefore, foreign matter having a large weight in the air is separated from the inside of the handle body 210 by inertia. Then, the separated heavy objects are sequentially stacked from the blocking wall 223. That is, the separated foreign matter is stored in the second flow path 214.

The air that has flowed along the second flow path 214 and struck the blocking wall 223 is then switched by the blocking wall 223 to flow through the connection path 216 again to the first flow path 212, respectively.

The present embodiment is similar to the second embodiment in other respects, but is characterized in that it further comprises a storage device for storing foreign matter separated from the first flow path.

Referring to FIG. 5, a storage device 250 is detachably coupled to a lower portion of the handle body 210 to store separated foreign objects. Since the storage device 250 serves as a cover for opening and closing the opening 224, the internal space of the storage device 250 forms a part of the second flow path 214.

In detail, a coupling part 240 for coupling the storage device 250 is formed on the lower side of the handle body 210.

The storage unit 250 is formed with a coupling protrusion 252 for coupling with the coupling unit 240 and a protrusion insertion slot 242 through which the coupling protrusion 252 is inserted is formed in the coupling unit 240 do.
