Fig. 1 is a view of a state in which a dust container is separated from a vacuum cleaner according to an embodiment, andFig. 2 is a cross-sectional view of a cleaner body according to an embodiment. - Referring to
Figs. 1 and2 , avacuum cleaner 1 according to an embodiment may include acleaner body 10 including a suction motor for generating a suction force therein, a dust separation mechanism mounted on thecleaner body 10 to separate dusts from suctioned air, and adust container 30 for storing the dusts separated from thedust separation mechanism 20. - Although not shown, the
vacuum cleaner 1 may further include a connection hose, a suction tube, and a suction nozzle. - The
cleaner body 10 may include a plurality ofmain wheels 11 andauxiliary wheels 12 for moving. - The
cleanser body 10 may include a main body inflow part through which the air suctioned through the suction nozzle is introduced. The air introduced into thecleaner body 10 through the mainbody inflow part 14 may be introduced into thedust separation mechanism 20. For example, the air introduced into thecleaner body 10 may be introduced into thedust separation mechanism 20 through a lower side of thedust separation mechanism 20. - The
cleaner body 10 may include amount part 13 on which thedust separation mechanism 20 and thedust collection 30 are mounted. For example, themount part 13 may be disposed on a front side of thecleaner body 10, but is not limited thereto. - After the
dust separation mechanism 20 is mounted first on themount part 12, and thedust container 30 may be mounted. When thedust container 30 is mounted on themount part 13, thedust container 30 may communicate with thedust separation mechanism 20. - The
cleaner body 10 may further include arotatable cover 15 covering thedust separation mechanism 20 and thedust container 30 in the state where thedust separation mechanism 20 and thedust container 30 are mounted on themount part 13.

dust container 30 is mounted on themount part 13, thedust container 30 may surround a portion of a circumference of thedust separation mechanism 20. Thus, when therotatable cover 15 covers thedust separation mechanism 20 and thedust container 30 after thedust separation mechanism 20 is mounted on themount part 13, and then thedust container 30 is mounted on themount part 13, thedust separation mechanism 20 may not be exposed to the outside of thecleaner body 10. - In the current embodiment, since the
dust separation mechanism 20 is covered by thedust container 30 and therotatable cover 15, thedust separation mechanism 20 may be fixed in position without a separate fixing unit for fixing thedust separation mechanism 20 to thecleaner body 10. That is, thedust container 30 and therotatable cover 15 may prevent thedust separation mechanism 20 from moving. - The
rotatable cover 15 may be coupled to thedust container 30 in the state where therotatable cover 15 covers thedust container 30. Alternatively, therotatable cover 15 may be coupled to thecleaner body 10 in the state where therotatable cover 15 covers thedust container 30. - When the

Also, thesecond protrusion 447 of theconnection guide 440 may be accommodated in a space between two contact protrusions adjacent to each other of the plurality ofcontact protrusions 456. When thesecond protrusion 447 is accommodated in the space between the twocontact protrusions 456, thesecond transmission part 430 may rotate together with theconnection part 450 when thesecond transmission part 430 rotates. - For another example, the

The plurality ofcontact protrusions 366 may protrude from an inner surface of theaccommodation groove 365 toward a center of theaccommodation groove 365 and be spaced apart from each other. A distance between the plurality ofcontact protrusions 366 may be greater than a thickness of thesecond protrusion 452 of theconnection part 450. Also, thesecond protrusion 452 of theconnection guide 450 may be accommodated in a space between twocontact protrusions 366 adjacent to each other of the plurality ofcontact protrusions 366. When thesecond protrusion 452 of theconnection part 450 is accommodated in the space between the twocontact protrusions 366, theconnection part 450 may rotate together with therotation shaft 364 when theconnection part 450 rotates. - For another example, the
rotatable shaft 364 may include a first accommodation groove in which thefirst protrusion 451 of theconnection part 450 is accommodated and a plurality of second accommodation grooves in which thesecond protrusion 452 of theconnection part 450 is accommodated. In this case, the plurality of second accommodation grooves may be disposed to be spaced a predetermined distance from each other. The arrangement of the plurality of second accommodation grooves may be equal to that of the plurality ofcontact protrusions 456 ofFig. 3 . - The
dust container cover 320 may include afirst body 321 and asecond body 330 coupled to an upper portion of thefirst body 321. One of the first andsecond bodies duct collection body 310. Also, theconnection part 450 may linearly movable and rotatably disposed on theduct container cover 320. - The
first body 321 may include afirst opening 321A through which theconnection part 450 passes and afirst guide 322 for guiding the linear movement of theconnection part 450 passing through thefirst opening 321A. Thefirst guide 322 may extend downward from thefirst opening 321A. - A
restriction rib 453 for restricting the downward movement of theconnection part 450 passing through theopening 321A may be disposed on theconnection part 450. Therestriction rib 453 protrudes along a circumference of theconnection part 450. Acontact part 454 may be disposed on therestriction rib 453. Thecontact part 454 may protrude downward from a bottom surface of therestriction rib 453. - The
first body 321 may include anelastic ring 324 contacting thecontact part 454 while theconnection part 450 moves downward and anaccommodation part 325 for accommodating theelastic ring 324. Since thecontact part 454 contacts theelastic ring 324 while theconnection part 450 moves downward, collision noises and damage of thecontact part 454 due to the collision may be reduced. Since the downward movement of theconnection part 450 may be restricted by theelastic ring 324, theelastic ring 324 may serve as a stopper. If therestriction rib 453 contacts theaccommodation part 325, theaccommodation part 325 may serve as the stopper. - The
second body 330 may include asecond opening 331 through which theconnection part 450 passes and asecond guide 332 for guiding the linear movement of theconnection part 450. Thesecond guide 332 may have a cylindrical shape. A portion of theconnection part 450 may be disposed within thesecond guide 332. - A
stopper 333 for restricting the upward movement of theconnection part 450 may be disposed on thesecond guide 332. While theconnection part 450 moves upward, therestriction rib 453 may contact thestopper 333 and thus may not further move. - In a state where the
first body 321 and thesecond body 330 are coupled to each other, the stopper 333 (that may be referred to as a "first stopper") and the elastic ring 324 (or the accommodation part) (that may be referred to as a "second stopper") may be spaced apart from each other. Thus, therestriction rib 453 may move between thestopper 333 and theelastic ring 324. Here, unless an external force is applied to theconnection part 450, theconnection part 450 may be maintained in the contact state with theelastic ring 324 by its self-weight. -
Figs. 5 and6 are views illustrating a process of connecting the driving unit to the pressing member. -
Fig. 5 illustrates a state in which the second transmission part and the connection part are connected to each other, and the connection part and the rotatable shaft of the pressing member are not connected to each other.Fig. 6 illustrates a state in which the second transmission part and the connection part are connected to each other, and the connection part and the rotatable shaft of the pressing member are connected to each other. Also,Fig. 4 illustrates a state in which the second transmission part and the connection part are connected to each other, and the connection part and the rotatable shaft of the pressing member are not connected to each other. - In the current embodiment, the connection between the second transmission part and the connection part may represent a state in which a rotation force of the second transmission part is transmissible into the connection part. Also, the connection between the connection part and the rotatable shaft of the pressing member may represent a case in which the rotation force of the connection part is transmissible into the rotatable shaft of the pressing member.
- Referring to
Fig. 4 , when therotatable cover 15 covers the upper side of theduct container 30 in the state where theduct container 30 is mounted on thecleaner body 10, thesecond transmission part 430, theconnection part 450, and therotatable shaft 364 of thepressing member 360 may be arranged in a line. For example, thesecond transmission part 430, theconnection part 450, and therotatable shaft 364 of thepressing member 360 may be aligned in a vertical direction. - Here, when the
second protrusion 447 of theconnection guide 440 is aligned with thecontact protrusion 456 of theconnection part 450, thesecond protrusion 447 of theconnection guide 440 may be pressed by thecontact protrusion 456 of theconnection part 450 to move to an upper side of theconnection guide 440, and then, theelastic member 438 may be contracted. In this state, the rotation force of thesecond transmission part 430 may not be transmitted into theconnection part 450. - In this case, when the
motor 410 is turned on to rotate thesecond transmission part 430 at a predetermined angle in a state where theconnection part 450 is stopped, thesecond protrusion 447 of theconnection guide 440 may be aligned with the space between the twocontact protrusions 456 of theconnection part 450. Thus, as illustrated inFig. 5 , thesecond protrusion 447 of theconnection guide 440 may be inserted into the space between the twocontact protrusions 456 of theconnection part 450 to transmit the rotation force of thesecond transmission part 430 into theconnection part 450. - Also, as illustrated in
Fig. 5 , when thesecond protrusion 452 of theconnection part 450 is aligned with thecontact protrusion 366 of therotatable shaft 364, thesecond protrusion 452 of theconnection part 450 may be pressed by thecontact protrusion 456 of theconnection part 450 to move to an upper side of theconnection guide 440, and then, theelastic member 438 may be contracted. In this state, the rotation force of theconnection part 450 may not be transmitted into thepressing member 360. However, when theconnection part 450 rotates at a predetermined angle in the state where thepressing member 360 is stopped, thesecond protrusion 452 of theconnection part 450 may be aligned with the space between the twocontact protrusions 366 of therotation shaft 364. Thus, as illustrated inFig. 6 , thesecond protrusion 452 of theconnection part 450 may be inserted into the space between the two contact protrusions 3666 of therotatable shaft 364 to transmit the rotation force of theconnection part 350 into thepressing member 360. - According to the current embodiment, the connection guide 40 may be movably disposed on the
rotatable cover 15, and theconnection part 450 may be movably disposed on theduct container cover 320. Thus, even though thesecond transmission part 430 and theconnection part 450 are not connected to each other, or theconnection part 450 and therotatable shaft 364 of thepressing member 360 are not connected to each other in the state where therotatable cover 15 covers thedust container 30, if thecompression motor 410 is turned on, thesecond transmission part 430 and theconnection part 450 are connected to each other while thesecond transmission part 430 rotates. In addition, while theconnection part 450 rotates, theconnection part 450 and the rotatable shaft of thepressing member 360 may be connected to each other. - Also, the
connection guide 440, theconnection part 450, and therotatable shaft 364 of thepressing member 360 may have the same center by thefirst protrusion 446 of theconnection guide 440 and thefirst protrusion 451 of theconnection part 450. Thus, the power of thecompression motor 410 may be stably transmitted into therotatable shaft 364 of thepressing member 360. - In the current embodiment, in the state where the
duct container cover 320 is coupled to thedust collection body 310, theconnection part 450 may move on thedust container cover 320 in a direction parallel to an extension direction of therotatable shaft 364 of thepressing member 360. -

lever 346 disposed on thehandle body 341 and thehandle cover 340 and first andsecond coupling parts lever 346. - The
lever 346 may include alever body 347 and apush part 348 extending upward from theleaver body 347 and pushed by the user. Thepush part 348 may be exposed to the outside of thehandle 340 through anopening 344 defined in thehandle cover 342. - The
push part 348 may be disposed to contact thefirst coupling part 350. Also, thefirst coupling part 350 may be supported by theelastic member 354. Thefirst coupling part 350 includes afirst body 353 supported by theelastic member 354 and afirst hook part 352 extending from thefirst body 353. Thefirst hook part 352 may pass through afirst hook hole 168 defined in therotatable cover 15 and then be hooked on therotatable cover 15. - The
first hook part 352 may be exposed to the outside of thehandle 340 through anopening 345 defined in thehandle cover 342. For another example, theopening 345 through which thefirst hook part 352 protrudes may be defined in thehandle body 341. - Although not shown, the
second coupling part 355 may be elastically supported by the elastic member. Thesecond coupling part 355 may include asecond hook part 356. Thesecond hook part 356 may be hooked on themount part 13 by asecond hook hole 132 defined in themount part 13. - When the
push part 348 of thelever 346 is pushed in the state where thefirst hook part 352 is hooked on therotatable cover 15, and thesecond hook part 356 is hooked on themount part 13, the first andsecond coupling parts 350 and the 355 rotate by thelever 346. As a result, thefirst hook part 352 may fall out thefirst hook hole 168, and thesecond hook part 356 may fall out thesecond hook hole 132. - Unlike the current embodiment, the
first coupling part 350 is not provided on thehandle 340, but is provided on therotatable cover 15. For another example, when therotatable cover 15 is not coupled to thedust container 30, but is coupled to one portion of thecleaner body 10, one of the first and second coupling parts may be omitted. - According to the current embodiment, since the lever is manipulated once to release the coupling between the
first coupling part 350 and therotatable cover 15 and between thesecond coupling part 355 and themount part 13, user's convenience may be improved. - Referring to
Fig. 8 , therotatable cover 15 may include afirst cover body 150, asecond cover body 160 coupled to thefirst cover body 150, and athird cover body 170 coupled to the first orsecond cover body - The

opening 154 through which theconnection guide 440 of thesecond transmission part 430 passes may be defined in thefirst cover body 150. Theopening 154 may be defined in thesecond accommodation part 153. Here, theconnection guide 440 may include ahook protrusion 444 for restricting the downward movement of theconnection guide 440 in the state where theconnection guide 400 passes through thehole 154.

Thesecond cover body 160 has afirst hole 162 through which a shaft of thecompression motor 410 passes and asecond hole 164 through which thesecond transmission part 430 passes. Thus, thesecond transmission part 430 may pass through thesecond hole 164 and theopening 154 to protrude to the outside (e.g., a lower side of the rotatable cover) of therotatable cover 15. - The
first hook hole 168 in which thefirst hook part 352 is inserted may be defined in thesecond cover body 160. - The
third cover body 170 may cover thefirst transmission part 420 and thesecond transmission part 430. Here, thethird cover body 170 may be formed of a transparent or translucent material so that the user sees the first andsecond transmission parts - That is, in the current embodiment, the

In this specification, the position of the rotatable cover that rotates at the first angle may be referred to as a first rotation position (or an automatic rotation position), and the position of the rotatable cover that rotates at the second angle may be referred to as a second rotation position (or manual rotation position). - Although the first
opening maintenance parts opening maintenance parts shaft support part 630 are integrated with each other inFig. 11 , the present disclosure is not limited thereto. For example, the firstopening maintenance parts opening maintenance parts shaft support part 630 may be separately provided with respect to each other. - Also, the
hinge guide 610 may be integrated with thecleaner body 10 or be coupled to thecleaner body 10. For another example, the firstopening maintenance parts opening maintenance parts shaft support part 630 may be integrated with thecleaner body 10, or each of the firstopening maintenance parts opening maintenance parts shaft support part 630 may be coupled to thecleaner body 10. - The first
opening maintenance parts elastic member 70, afirst support part 621 supporting one end of theelastic member 70, and asecond support part 622 supporting the other end of theelastic member 70. Here, at least one of the first andsecond support parts cleaner body 10 or be coupled to thecleaner body 10. - A
hole 623 through which thecontact part 185 of thehinge body 181 passes may be defined in thefirst support part 621.

Thecontact part 185 may press theelastic member 70 according to the rotation angle of thehinge body 181 to contract theelastic member 70. For another example, the twofirst support parts 621 may be spaced apart from each other to form thehole 623. - Also, in the state where the
contact part 185 passes through thehole 623 to contact theelastic member 70, theelastic member 70 may elastically support thecontact part 185 of thehinge body 181.

-
Fig. 12 is a view of the rotatable cover and the opening maintenance unit in a state where the rotatable cover is not opened (does not rotate),Fig. 13 is a view of the rotatable cover and the opening maintenance unit in the state where the rotatable cover rotates at the first angle, andFig. 14 is a view of the rotatable cover and the opening maintenance unit in the state where the rotatable cover rotates at the second angle.Fig. 15 is a perspective view of the cleaner body in the state where the rotatable cover rotates at the second angle, andFig. 16 is a view of a state in which a dust separation mechanism is separated in the state where the rotatable cover rotates at the second angle. - Referring to
Figs. 11 and12 , when therotatable cover 15 is coupled to thedust container 30, thecontact part 185 of thehinge body 181 may pass through thehole 623 of thefirst support part 621 to press theelastic member 70, thereby contracting theelastic member 70. When theelastic member 70 is contracted, one end of theelastic member 70 may be spaced apart from thefirst support part 621. - In this state, when the coupling between the
first coupling part 350 and therotatable cover 15 is released, and also, the coupling between thesecond coupling part 355 and themount part 13 is released, theelastic member 70 may push thecontact part 185 of thehinge body 181 by the elastic force of theelastic member 70 as illustrated 13. Thus, therotatable cover 15 may automatically rotate upward with respect to thehinge shaft 186. - While the
elastic member 70 pushes thecontact part 185 of thehinge body 181, when therotatable cover 15 rotates at a first angle θ1 with respect to thehinge shaft 186, theelastic member 70 may contact thefirst support part 621. Then, theelastic member 70 may be stopped. - In this state, an end of the
contact part 185 of thehinge body 181 may be disposed in thehole 623 of thefirst support part 621 to contact one end of theelastic member 70. Here, theelastic member 70 may have an elastic force greater than the downward rotation force due to the self-weight of therotatable cover 15. Thus, therotatable cover 15 may be maintained to the rotating state thereof by theelastic member 70 in the state where therotatable cover 15 rotates at the first angle. - Even though an external force is applied to the
rotatable cover 15 in the state where therotatable cover 15 rotates at the first angle, and then is removed after therotatable cover 15 rotates downward, if therotatable cover 15 is not coupled to thefirst coupling part 350, therotatable cover 15 may rotate again upward by theelastic member 70 to maintain the opened state thereof. - Referring to
Figs. 14 and15 , when the user lifts therotatable cover 15 upward in the state of theFig. 13 , therotatable cover 15 may rotate upward with respect to thehinge shaft 186 of thehinge body 181. Here, when therotatable cover 15 rotates upward at the first rotation position, thecontact part 185 may be spaced apart from theelastic member 70 to fall out thehole 623. - While the
rotatable cover 15 rotates upward, thehinge body 181 may contact thesupport protrusion 636 to interfere with thesupport protrusion 636. In this state, if the rotation force is further applied to therotatable cover 15, thehinge body 181 and/or thesupport rib 634 may be elastically deformed to release the interference between thesupport protrusion 636 and thehinge body 181. Also, when the force for rotating therotatable cover 15 upward is removed in the state where therotatable cover 15 rotates at the second angle θ2, thehinge body 181 of therotatable cover 15 may be supported by thesupport protrusion 636 and maintained in the opened state thereof. Here, unless the force for rotating therotatable cover 15 downward is applied to therotatable cover 15, thehinge body 181 or thesupport rib 634 may not be elastically deformed by the self-weight thereof and be maintained in the state in which thehinge body 181 is seated on thesupport protrusion 636. - In the state of
Fig. 15 , thedust separation mechanism 20 may be separated from thecleaner body 10. Here, thedust separation mechanism 20 may be separated together with anair flow guide 80. Here, theair flow guide 80 may be separably connected to a lower portion of thedust separation mechanism 20. Theair flow guide 80 may guide air discharged from thedust separation mechanism 20 toward the suction motor and include a filter. - According to the current embodiment, since the rotatable cover is maintained in the rotating state (opened state) by the opening maintenance unit, the dust container may be easily mounted on or separated from the mount part without interfering with the rotatable cover.
- Also, since the rotatable cover is maintained in the opened state at the first rotation position when the rotatable cover is not mounted on the dust container or is not coupled to the dust container, whether the dust container is mounted, or whether the rotatable cover is coupled to the dust container may be easily confirmed.
- Also, since the rotatable cover including the power transmission part is maintained in the rotating state by the opening maintenance unit, the interference between the dust container and the power transmission part while the dust container is mounted on the mount part may be prevented to prevent the power transmission part from being damaged.
- Although the opening maintenance unit includes the first and second opening maintenance parts in the foregoing embodiment, the present disclosure is not limited thereto. For example, the opening maintenance unit may include only one of the first and second opening maintenance parts according to a kind of cleaner.
- Although embodiments have been described with reference to a number of illustrative embodiments thereof, it should be understood that numerous other modifications and embodiments can be devised by those skilled in the art that will fall within the spirit and scope of the principles of this disclosure. More particularly, various variations and modifications are possible in the component parts and/or arrangements of the subject combination arrangement within the scope of the disclosure, the drawings and the appended claims. In addition to variations and modifications in the component parts and/or arrangements, alternative uses will also be apparent to those skilled in the art.
