Definitions
- the present disclosure relates to a vacuum cleaner. More particularly, the present disclosure relates to a vacuum cleaner that can selectively be used in either a canister form or a stick form.
- a vacuum cleaner is classified into a canister vacuum cleaner, a stick vacuum cleaner, etc.
- the canister vacuum cleaner is usually configured, so that a cleaner body and a suction nozzle are separated from each other and at the same time, in fluid connecttion with each other through an extended tube and a flexible hose.
- a canister vacuum cleaner is advantageous in that since to clean a surface to be cleaned, only the suction nozzle is moved along the surface to be cleaned, the cleaning operation can be carried out with a relatively small force. Accordingly, the canister vacuum cleaner is good to clean a relatively wide cleaning area.
- the canister vacuum cleaner is disadvantageous in that since the cleaner body and the suction nozzle are connected to each other through the extended tube and the flexible hose, an entire length thereof is lengthened. Thus, the canister vacuum cleaner is difficult to handle and keep.
- the stick vacuum cleaner is configured, so that the suction nozzle is integrally formed with the vacuum cleaner, which is moved along the surface to be cleaned.
- an elongated handle or stick is formed on the cleaner body.
- the stick vacuum cleaner is advantages in that since its length or volume is reduced, it is relatively easy to handle and keep.
- the stick vacuum cleaner is disadvantages in that since to clean the surface to be cleaned in cleaning, both the cleaner body and the suction nozzle are moved along the surface to be cleaned, the cleaning operation should be carried out with a relatively large force.
- the stick vacuum cleaner is good to clean a relatively small cleaning area in a short time.
- the canister vacuum cleaner and the stick vacuum cleaner Accordingly, if user possesses both the canister vacuum cleaner and the stick vacuum cleaner, she or he will select either the canister vacuum cleaner or the stick vacuum cleaner according to cleaning conditions including a size and area of cleaning area in cleaning, thereby allowing her or him to more easily and conveniently clean the cleaning area.

Abstract
Description
- The present disclosure relates to a vacuum cleaner. More particularly, the present disclosure relates to a vacuum cleaner that can selectively be used in either a canister form or a stick form.
- In general, a vacuum cleaner is classified into a canister vacuum cleaner, a stick vacuum cleaner, etc.
- The canister vacuum cleaner is usually configured, so that a cleaner body and a suction nozzle are separated from each other and at the same time, in fluid connecttion with each other through an extended tube and a flexible hose. Such a canister vacuum cleaner is advantageous in that since to clean a surface to be cleaned, only the suction nozzle is moved along the surface to be cleaned, the cleaning operation can be carried out with a relatively small force. Accordingly, the canister vacuum cleaner is good to clean a relatively wide cleaning area. However, the canister vacuum cleaner is disadvantageous in that since the cleaner body and the suction nozzle are connected to each other through the extended tube and the flexible hose, an entire length thereof is lengthened. Thus, the canister vacuum cleaner is difficult to handle and keep.
- To the contrary, the stick vacuum cleaner is configured, so that the suction nozzle is integrally formed with the vacuum cleaner, which is moved along the surface to be cleaned. To move and carry the cleaner body, an elongated handle or stick is formed on the cleaner body. Accordingly, the stick vacuum cleaner is advantages in that since its length or volume is reduced, it is relatively easy to handle and keep. However, the stick vacuum cleaner is disadvantages in that since to clean the surface to be cleaned in cleaning, both the cleaner body and the suction nozzle are moved along the surface to be cleaned, the cleaning operation should be carried out with a relatively large force. Thus, the stick vacuum cleaner is good to clean a relatively small cleaning area in a short time.
- Accordingly, if user possesses both the canister vacuum cleaner and the stick vacuum cleaner, she or he will select either the canister vacuum cleaner or the stick vacuum cleaner according to cleaning conditions including a size and area of cleaning area in cleaning, thereby allowing her or him to more easily and conveniently clean the cleaning area. However, possessing both the canister vacuum cleaner and the stick vacuum cleaner may not only be stressful in economics, but also it is undesirable in use efficiency.
- Therefore, there is need for vacuum cleaners that can selectively used in either the canister form or the stick form, as occasion demands.
- An aspect of the present disclosure is to address at least the above problems and/or disadvantages and to provide at least the advantages described below. Accordingly, an aspect of the present disclosure is to provide a vacuum cleaner that is capable of selectively being used as one of the canister form and the stick form as occasion demands, thereby allowing user's economic burden to reduce and allowing the vacuum cleaner to improve use efficiency.
- Another aspect of the present disclosure is to provide a vacuum cleaner that can be used in both a canister form and a stick form, capable of being easily changed into one of the canister form and the stick form by simple actions, thereby increasing user's convenience.
- In accordance with an aspect of the present disclosure, a vacuum cleaner for use in either a canister form and a stick form includes a cleaner body, a suction unit having an air suction opening formed in a bottom surface of the cleaner body to drawn in air, a dust collecting unit disposed in the cleaner body to separate dust or dirt from the air and to collect and store the dust or dirt therein, and a mode selecting unit disposed on the cleaner body to select one of a first mode and a second mode. Here, the first mode is a mode where a handle member for moving the cleaner body is connected to the cleaner body and the suction unit and the dust collecting unit are communicated with each other and the second mode is a mode where an external accessory is connected to the cleaner body to communicate with the dust collecting unit.
- The dust collecting unit may include at least one cyclone, and a dust bin unit to collect and store the dust or dirt separated by the cyclone therein. At this time, the cyclone may includes a cyclone body disposed in such a manner that a longitudinal axis thereof is horizontally arranged and having an air inlet and an air outlet, a guide member disposed on one side of the cyclone body in the cyclone body to guide the air flowing in through the air inlet, an outflow pipe disposed on the other side of the cyclone body to communicate with the air outlet, and a dust discharging opening formed to a portion of the other side of the cyclone body to face the dust bin unit. In addition, the dust bin unit may include a dust bin detachably disposed on the cleaner body to be parallel thereto and having an opened end to communicate with the dust discharging opening. To prevent the dust or dirt from spilling from the dust bin when it is dumped, the dust bin may include a dust spilling-prevention cover formed in such a size that at least a portion of the opened end of the dust bin is closed up, and elastically supported on a bottom portion of the opened end of the dust bin in such a manner that when the dust bin is mounted in the cleaner body, the dust spilling-prevention cover is folded in a direction of closing up the opened end of the dust bin and when the dust bin is removed from the cleaner body, the dust spilling-prevention cover is unfolded in a direction of opening the opened end of the dust bin.
- The mode selecting unit may include a handle connecting part disposed on the cleaner body to detachably fix the handle member, and a passage switching part disposed on an air passage between the suction unit and the dust collecting unit, so that the external accessory can be connected thereto. The passage switching part selectively communicates one of between the external accessory and the dust collecting unit and between the suction unit and the dust collecting unit according to whether the external accessory is connected thereto. At this time, the handle member may include one of a tube shape having a grip or an operating handle, a stick shape having a grip, a shape in which an extended tube and the operating handle are connected with each other, and a shape in which the extended tube, the operating handle and a flexible hose are connected to one another. Also, the external accessory may include one of a suction nozzle assembly in which a suction nozzle and a flexible hose are connected with each other, and a suction nozzle/handle assembly in which the suction nozzle, an extended tube, an operating handle and the flexible hose are connected with one another.
- The handle connecting part may include a pivot body disposed on one side of the cleaner body to be pivotable in a certain angle, and a fixing member to detachably fix a lower end of the handle member to the pivot body. The fixing member may include a fixing protrusion formed on an upper end of the pivot body, and a protrusion-accommodating hole formed in the lower end of the handle member to accommodate the fixing protrusion.

-
FIG. 1 is a perspective view exemplifying a vacuum cleaner for use in either a canister form or a stick form according to an exemplary embodiment of the present disclosure, andFIG. 2 is a cross-sectional top plan view of the vacuum cleaner illustrated inFIG. 1 . - As illustrated in
FIGS. 1 and 2 , thevacuum cleaner 1 for use in either the canister form or the stick form according to the exemplary embodiment of the present disclosure includes acleaner body 10, asuction unit 20, adust collecting unit 40, and amode selecting unit 60. - To move the
cleaner body 10 along a surface to be cleaned, left andright wheels cleaner body 10. As illustrated inFIG. 2 , in the rear of thecleaner body 10 on which the left and theright wheels suction motor 21 by which a suction force is provided and acord reel 18 on which an electric cord is wound. If an external power is not used as a power for driving thesuction motor 21 of thevacuum cleaner 1, a battery (not illustrated) may be installed in the place on which thecord reel 18 is disposed, instead of thecord reel 18, - The
suction unit 20, which draws in dust or dirt adhered to the surface to be cleaned in a first cleaning mode to be described later, is installed in a lower side of the front of thecleaner body 10. As illustrated inFIG. 3A , thesuction unit 20 has an air suction opening 22 formed in a bottom surface of thecleaner body 10. Alternatively, to increase an efficiency for drawing in the dust or dirt adhered to the surface to be cleaned, thesuction unit 20 can further include a brush (not illustrated) implanted in the vicinity of the air suction opening 22, or a brush roller (not illustrated) rotatably disposed on the bottom surface of thecleaner body 10. - The dust collecting
unit 40, which separates and collects the dust or dirt from the drawn-in air by using the suction force of thesuction motor 21, is disposed inside the front of thecleaner body 10. As illustrated inFIG. 2 , thedust collecting unit 40 includes acyclone 41, adust bin unit 58, and afilter 65. - The
cyclone 41 separates relatively large dust or dirt out of the air drawn in from the outside by the suction force of thesuction motor 21. For this, thecyclone 41 is provided with acyclone body 43 disposed inside the front of thecleaner body 10 in such a manner that a longitudinal axis thereof is horizontally arranged. Thecyclone body 43 is formed in a cylinder shape having anair inlet 44 and anair outlet 45 formed in one side of a front end and the middle of a rear end thereof, respectively. To guide the air drawn into thecyclone body 43 through theair inlet 44, aguide member 46 is disposed in a front end side of thecyclone body 43. Theguide member 46 is provided with aguide pipe 47 and aspiral blade 48, so that it guides the air drawn into thecyclone body 43 to whirl in a spiral shape. Anoutflow pipe 49 is disposed in a rear end side of thecyclone body 43, so that it communicates with theair outlet 45. Theoutflow pipe 49 guides the air whirling in the spiral shape by means of theguide member 46 in thecyclone body 43 to rotate in a spiral shape and at the same time, to discharge through theair outlet 45. Adust discharging opening 50 is formed in one side of the rear end of thecyclone body 43, so that it faces adust guide 51. Thedust guide 51 guides the dirt or dust discharged through thedust discharging opening 50 due to the centrifugal force, into adust bin 59 of thedust bin unit 58, which will be described. - The
dust bin unit 58 collects and stores the dust or dirt discharged along thedust guide 51 through thedirt discharging opening 50 thereon. Thedust bin unit 58 includes adust bin 59, which is disposed detachably and parallel to thecleaner body 10. Thedust bin 59 is formed in a hexahedral bin shape having an openedend 59a, which communicates with thedust guide 51. Preferably, but not necessarily, thedust bin 59 is formed of a transparent plastic material so as to allow a user to easily perceive whether it is filled with the dust or dirt. On an upper surface of thedust bin 59 is formed a dust bin handle 69 for moving thedust bin 59 to mount in or remove from thecleaner body 10. - As illustrated in
FIGS. 3A and 3B , to prevent the dust or dirt from spilling to the outside when thedust bin 59 is separated and removed from thecleaner body 10, a dust spilling-prevention cover 61 is disposed on a bottom portion of the openedend 59a of thedust bin 59. The dust spilling-prevention cover 61 is made up of a rectangular plate formed in such a size that at least a portion of the openedend 59a of thedust bin 59 is closed up. The dust spilling-prevention cover 61 is elastically supported on the bottom portion of the openedend 59a of thedust bin 59 by anelastic spring 62 in such a manner that when thedust bin 59 is mounted in thecleaner body 10 as illustrated inFIG. 3B , it is folded in a direction of closing up the openedend 59a of thedust bin 59 and when thedust bin 59 is removed from thecleaner body 10 as illustrated inFIG. 3A , it is unfolded in a direction of opening the openedend 59a of thedust bin 59. - To fix the
dust bin 59 in a state where it comes in close contact with thedust guide 51, a fixing and detachinglever 63 is disposed on a front end side of thedust bin 59 in thecleaner body 10. The fixing and detachinglever 63 is provided with acam 64 having a cam surface, which presses a front end surface of thedust bin 59 while coming in contact therewith or which is separated from the front end surface of thedust bin 59, according to a rotated angle. Accordingly, after thedust bin 50 is mounted in thecleaner body 10, if the fixing and detachinglever 63 is rotated in such a direction that the cam surface of thecam 64 presses the front end surface of thedust bin 59 while coming in contact therewith, thedust bin 59 is fixed in a state where a rear end surface thereof comes in close contact with thedust guide 51. - The
filter 65 separates minute dust or dirt, which is not separated by thecyclone 41, and is disposed between thesuction motor 21 and theair outlet 45 of thecyclone body 43 of thecyclone 41. Thefilter 65 may be made up of a sponge type filter, a high efficiency particulate arrestor (HEPA) filter, or a combination thereof. A filter handle 67 for mounting and dismounting thefilter 65 in and from thecleaner body 10 is disposed on an upper part of thefilter 65, which is projected to the outside of thecleaner body 10. - As illustrated in
FIGS. 5 and7 , themode selecting unit 60 allows the user to change thecleaner body 10 into either a first cleaning mode (seeFIG. 5 ) for using as a stick form or a second cleaning mode (seeFIG. 7 ) for using as a canister form according to user's need. Here, the first cleaning mode is a mode where ahandle member 15 for using thecleaner body 10 as the stick form is connected to thecleaner body 10 and thesuction unit 20 and thedust collecting unit 40 are communicated with each other, and the second cleaning mode is a mode where thehandle member 15 is removed from thecleaner body 10 and an external accessory for using thecleaner body 10 in the canister form is connected to thecleaner body 10 to communicate with thedust collecting unit 40. Thehandle member 15 is made up of a tube with a grip, as illustrated inFIG.5 , and is provided as an accessory, which is selectively usable according user's need, by a manufacturing company. The external accessory is made up of a suction nozzle/handle assembly including asuction nozzle 16, a variableextended tube 17, anoperating handle 18, and aflexible hose 19, as illustrated inFIG. 7 . - The
mode selecting unit 60 includes a handle connecting part 80 (seeFIGS. 1 and5 ) disposed on thecleaner body 10 to detachably fix thehandle member 15, and a passage switching part 70 (seeFIGS. 4A and 4B ) to selectively communicate either between thesuction nozzle 16 and thedust collecting unit 40 or between thesuction unit 20 and thedust collecting unit 40 according to whether the external accessory, that is, theflexible hose 19 of the suction nozzle/handle assembly is connected to thecleaner body 10. - As illustrated in
FIGS. 1 and5 , thehandle connecting part 80 is made up of apivot body 81 and a fixingmember 83. Thepivot body 81 is formed of a T-lettered tube having both ends disposed on a rotating axis (not illustrated) of anupper portion 11 of thecleaner body 10 to be pivotable in a certain angle, for example, an angle of 60 through 90 degrees. The fixingmember 83, which detachably fixes a lower end of thehandle member 15 to thepivot body 81, is provided with a fixing protrusion 85 (seeFIG. 1 ) formed on an upper end of thepivot body 81 to be elastically ascendable and descendable, and a protrusion-accommodating hole 86 (seeFIG. 5 ) formed in the lower end of thehandle member 15 to accommodate the fixingprotrusion 85. When the lower end of thehandle member 15 is inserted around an outer circumferential surface of the upper end of thepivot body 81, the fixingprotrusion 85 is inserted into the protrusion-accommodatinghole 86, and thus the lower end of thehandle member 15 is fixed to the upper end of thepivot body 81. On the lower end of thehandle member 15 in the vicinity of the protrusion-accommodatinghole 86 is disposed a pushingbutton 87, which pushes down the fixingprotrusion 85 inserted in the protrusion-accommodatinghole 86 to release a locking connection between the fixingprotrusion 85 and the protrusion-accommodatinghole 86. - Alternatively, the fixing
member 83 can be formed in the form of other connecting members, such as male and female screws. - As illustrated in
FIG. 5 , to maintain thehandle member 15 in a vertical position in stand-by or storage, a position maintaining member (not illustrated) can be formed between thepivot body 81 and anupper portion 11 of thecleaner body 10 corresponding thereto. The position maintaining member may be made up of at least one projection (not illustrated) formed on thepivot body 81, and a projection-accommodating groove (not illustrated) in theupper portion 11 of thecleaner body 10 corresponding to the projection. - Accordingly, in the first cleaning mode, when the
handle member 15 is fixed to thepivot body 81 through the fixingmember 83, it can be pivoted in the range of the certain angle, that is, the angle of 60 through 90 degrees, by thepivot body 81. - As illustrated in
FIGS. 4A, 4B and7 , thepassage switching part 70 is disposed on an air passage between thesuction unit 20 and thedust collecting unit 40, so that theflexible hose 19 of the suction nozzle/handle assembly can be connect thereto. Thepassage switching part 70 includes atube member 71 and a blockingmember 77. Thetube member 71 is formed of a T-lettered or Y-lettered tube connected to thesuction unit 20 or thesuction unit 20 and a connectingpart 19a of theflexible hose 19 to communicate thesuction unit 20 or thesuction nozzle 16 with thecyclone 41. Thetube member 71 is provided with afirst tube part 72 having one end detachably connected with the connectingpart 19a, asecond tube part 73 having one end connected with thesuction unit 20, and athird tube part 74 having one end connected with the other ends of the first and thesecond tube parts cyclone 41. Although there is not illustrated, the connection between the connectingpart 19a and thefirst tube part 71 can be obtained by various methods, such as a screw connection or a hooking connection as in the fixingmember 83 explained with reference toFIGS. 1 and5 , within the limit that a certain airtightness is maintain between the connectingpart 19a and thefirst tube part 71 so as not to deteriorate the suction pressure. - The blocking
member 77 is made up of a blockingplate 78 pivotably supported between aninlet portion 74b of thethird tube part 74 toward thesecond tube part 73 and aninlet portion 74a of thethird tube part 74 toward thefirst tube part 72, so that it can be moved between a first position (seeFIG. 4A ) where it closes up theinlet portion 74a of thethird tube part 74 toward thefirst tube part 72 and a second position (seeFIG. 4B ) where it closes up theinlet portion 74b of thethird tube part 74 toward thesecond tube part 73. The blockingplate 78 is elastically urged by anelastic spring 79, so that it is maintained in the first position. Accordingly, the blockingplate 78 is moved to the second position by the connectingpart 19a of theflexible hose 19 moving against the elastic restoring force of theelastic spring 79 when the connectingpart 19a is connected to thefirst tube part 72 for the second cleaning mode, as illustrated inFIG. 4B , and returned to the first position by an elastic restoring force of theelastic spring 79 when the connectingpart 19a is removed from thefirst tube part 72 for the first cleaning mode, as illustrated inFIG. 4A . - In the above description, although the
handle member 15 is illustrated and explained as formed in the tube shape having the grip as illustrated inFIG. 5 , the present disclosure is not limited thereto. For instance, thehandle member 15 can be formed in a tube shape having an operating panel (not illustrated), a stick shape (not illustrated) having a grip, a shape in which the variableextended tube 17 and the operating handle 18 provided as accessories are connected with each other, as illustrated inFIG. 6A , or a shape in which the variableextended tube 17, the operatinghandle 18 and theflexible hose 19 are connected to one another, as illustrated inFIG. 6B . - Also, although the suction nozzle/handle assembly in which the
suction nozzle 16, the variableextended tube 17, the operatinghandle 18 andflexible hose 19 are connected with one another is illustrated and explained as used as the external accessory for using thecleaner body 10 as the canister form, the present disclosure is not limited. For instance, as illustrated inFIG. 8 , a suction nozzle assembly in which asuction nozzle 14 for cleaning a narrow area and aflexible hose 19 are connected with each other can be used as the external accessory. - Hereinafter, an operation of the
vacuum cleaner 1 for use in either the canister form or the stick form will be now explained in detail with reference toFIGS. 1 through 5 and7 . - First, it is assumed that the
cleaner body 10 is in a state illustrated inFIG. 1 . In this state, to quickly clean a relatively narrow cleaning area, if the user want to use thecleaner body 10 as the stick form, that is, the first cleaner mode, she or he inserts the lower end of thehandle member 15 around the upper end of thepivot body 81. At this time, the fixingprotrusion 85 is inserted into the protrusion-accommodatinggroove 86, and thus the lower end of thehandle member 15 is fixed to the upper end of thepivot body 81. As a result, thehandle member 15 can be pivoted up and down in the range of a certain angle, that is, an angle of 60 through 90 degrees, with respect to thecleaner body 10 by thepivot body 81. - At this time, since the
passage switching part 70 in the state illustrated inFIG. 1 , the blockingplate 78 of the blockingmember 77 is positioned in the first position by theelastic spring 79, as illustrated inFIG. 4A . That is, the blockingplate 78 closes up thefirst tube part 72 of thetube member 71 to block the air passage between the outside and thedust collecting unit 40 and opens thesecond tube part 73 to open the air passage between thesuction unit 20 and thedust collecting unit 40. - Under the state, if the
vacuum cleaner 1 is supplied with the power and at the same time, thecleaner body 10 is moved along a surface to be cleaned in the relatively narrow cleaning area, air laden with dust or dirt is drawn into thecyclone body 43 through theair suction opening 22 of thesuction unit 20, thesecond tube part 73 of thetube member 71 and theair inlet 44 from the surface to be cleaned. The drawn-in air forms a whirling current through theguide member 46 and theoutflow pipe 49. As a result, relatively large dust or dirt included in the drawn-in air is discharged through thedust discharging opening 50 due to the centrifugal force, and collected and stored in thedust bin 59 through thedust guide 51. And, the dust-removed air passes through theoutflow pipe 49 and is discharged to amotor chamber 23 in which thesuction motor 21 is installed, through theair outlet 45 and thefilter 65. Here, dust or dirt larger than minute holes of thefilter 65 does not flow into themotor chamber 23, but is filtered. The air flowing into themotor chamber 23 is discharged to the outside through anair discharging passage 24. - After the cleaning operation is completed as described above, if the user wants to dump the dust or dirt collected and stored in the
dust bin 59, she or he rotates the fixing and detachinglever 63 in a certain angle. As a result, the cam surface of thecam 64 is separated from the front end surface of thedust bin 59, so that the rear end surface of thedust bin 59 is released from a state where it is fixed while coming in compression contact with thedust guide 51. Thus, thedust bin 59 can freely be removed from thecleaner body 10 with the dust bin handle 69. At this time, as illustrated inFIG. 3A , since the dust spilling-prevention cover 61 is unfolded parallel to a bottom surface of thedust bin 59 due to the elastic force of theelastic spring 62, the dust or dirt in thedust bin 59 is not spilled to the outside from thedust bin 59. - After that, as illustrated in
FIG. 7 , to clean a relatively wide cleaning area, if the user want to use thecleaner body 10 as the canister form, that is, the second cleaning mode, she or he separates and removes the lower end of thehandle member 15 from the upper end of thepivot body 81. At this time, the fixingprotrusion 85 is pushed down by the pushingbutton 87, so that it releases a locking to the protrusion-accommodatinggroove 86. - And then, as illustrated in
FIG. 4B , the connectingpart 19a of theflexible hose 19 of the suction nozzle/handle assembly is inserted into and fixed to thefirst tube part 72 of thetube member 71. At this time, the blockingplate 78 of the blockingmember 77 is pushed against theelastic spring 79 by the connectingpart 19a, so that it is moved to the second position. That is, the blockingplate 78 closes up thesecond tube part 73 of thetube member 79 to block the air passage between thesuction unit 20 and thedust collecting unit 40 and opens thefirst tube part 72 to open the air passage between thesuction nozzle 16 and thedust collecting unit 40. - Under the state, if the
vacuum cleaner 1 is supplied with the power and at the same time, thecleaner body 10 is moved along a surface to be cleaned in the relatively wide cleaning area, air laden with dust or dirt is drawn into thecyclone body 43 through an air suction opening (not illustrated) of thesuction nozzle 16, the variableextended tube 17, the operatinghandle 18, theflexible hose 19, thefirst tube part 72 of thetube member 71, and theair inlet 44 from the surface to be cleaned. The air drawn in thecyclone body 43 passes through thedust collecting unit 40 and thefilter 65 to remove the dust or dirt included therein and then goes out of thecleaner body 10 to the outside, in the same method as described above. - As apparent from the foregoing description, according to the exemplary embodiments of the present disclosure, the vacuum cleaner for use in either the canister form or the stick form is configured, so that it can be selected and used as either the canister form or the stick form according to the cleaning conditions including the size and the area of cleaning area in cleaning. Accordingly, the user does not need to possess both the canister vacuum cleaner and the stick vacuum cleaner to satisfy the various cleaning conditions, as in the conventional vacuum cleaners. Thus, the user's economical burden is not only reduced, but also the use efficiency for the cleaner can be improved.
- Further, the vacuum cleaner for use in either the canister form or the stick form according to the exemplary embodiments of the present disclosure is configured, so that it can easily changed into the canister form or the stick form only by the operation of mounting the handle member, or the operations of dismounting the handle member and mounting the suction nozzle and/or handle assembly. Accordingly, the vacuum cleaner for use in either the canister form or the stick form according to the exemplary embodiments of the present disclosure is convenient and easy to use.
- Also, the vacuum cleaner for use in either the canister form or the stick form according to the exemplary embodiments of the present disclosure is configured, so that the dust bin formed of the transparent plastic material is detachably fixed to the cleaner body. Accordingly, the dust or dirt collected and stored in the dust bin can be easily and frequently dumped, thereby preventing the dust-separating efficiency from being deteriorating due to the re-scattering of the dust or dirt collected and stored in the dust bin.
- Although representative exemplary embodiments of the present disclosure have been shown and described in order to exemplify the principle of the present disclosure, the present disclosure is not limited to the specific embodiments. It will be understood that various modifications and changes can be made by one skilled in the art without departing from the spirit and scope of the disclosure as defined by the appended claims. Therefore, it shall be considered that such modifications, changes and equivalents thereof are all included within the scope of the present disclosure.
