[0030] Reference will now be made in detail to the embodiments of the present disclosure,
examples of which are illustrated in the accompanying drawings, wherein like reference
numerals refer to like elements throughout.
[0031] Hereinafter, a vacuum cleaner according to a first embodiment of the present disclosure
will be described in detail with reference to the drawings.
[0032] As illustrated in FIGS. 1 to 4, a vacuum cleaner according to a first embodiment
of the present disclosure includes a first cleaner module 1100 capable of cleaning
a floor in an upright mode, and a second cleaner module 1200 that is removably installed
on the first cleaner module 1100 and is capable of doing cleaning in a handy mode
(handheld mode) after separation from the first cleaner module 1100.
[0033] The first cleaner module 1100 includes a first body 1110 in which a first fan motor
(not shown) for generating a suction force is housed; a head unit 1120 that is connected
to a front side of the first body 1110, comes into contact with a floor to be cleaned,
and suctions dust on the floor along with air; a first dust collection unit 1130 that
separates the dust from the air suctioned through the head unit 1120 by the suction
force generated from the first fan motor; a wheel assembly 1140 that is mounted on
the first body 1110 and allows the first body 1110 to move along the floor to be cleaned;
and an extension frame 1150 that extends upwardly from the first body 1110. The second
cleaner module 1200 is removably installed on the extension frame 1150.
[0034] The first fan motor for generating the suction force is mounted in the first body
1110, and the first body 1110 can move along the floor through the wheel assembly
1140. Further, the first dust collection unit 1130 described above is mounted on an
upper portion of the first body 1110.
[0035] The head unit 1120 is provided with a suction port (not shown) in a bottom thereof
so as to receive the suction force generated from the first fan motor to suction the
dust from the floor to be cleaned. The suction port (not shown) that receives the
suction force to suction foreign materials along with air, and a brush (not shown)
that is rotatably installed in the suction port so as to be able to easily clean,
for instance, a carpet are disposed on the bottom of the head unit 1120.
[0036] The first dust collection unit 1130 receives the air suctioned by the head unit 1120,
separates the dust included in the air, and collects the separated dust. In the present
embodiment, the first dust collection unit 1130 separates and collects the dust from
the air in a cyclone mode.
[0037] The wheel assembly 1140 includes a pair of wheels 1141 disposed on both left and
right sides, and a wheel bracket 1142 on which the two wheels 1141 are rotatably installed
and which rotatably supports the first body 1110.
[0038] The second cleaner module 1200 includes a second body 1210 in which a second fan
motor (not shown) for generating a suction force is housed; an extension pipe 1220
that is provided at one side of the second body 1210 so as to enable a user to do
cleaning in a separated state from a target to be cleaned; a second dust collection
unit 1230 that separates the dust from the air suctioned through the extension pipe
1220 and collects the separated dust; and an extension cable 1240 and a plug 1250
which are used for connection to an external power supply (not shown). The second
body 1210 includes a handle 1211 at one side thereof such that the user can grasp
the handle to use the second cleaner module 1200.
[0039] The second fan motor for generating the suction force is mounted in the second body
1210. Based on the drawings, the aforementioned handle 1211 is provided at an upper
end of the second body 1210, and the aforementioned extension pipe 1220 is connected
to a lower end of the second body 1210.
[0040] The extension pipe 1220 is removably installed on the second body 1210. The extension
pipe 1220 is connected to the second body 1210 such that air can be suctioned through
the extension pipe 1220, or the extension pipe 1220 is separated from the second body
1210 such that air can be directly suctioned to the second body 1210.
[0041] As illustrated in FIG. 5, a damper 1214 for preventing foreign materials from leaking
through the extension pipe 1220 is disposed inside the second body 1210. The damper
1214 is disposed on a channel that connects the extension pipe 1220 and the second
fan motor, and selectively opens/closes the channel according to an operation of the
second fan motor. Further, the damper 1214 also serves to prevent the foreign materials
from leaking through the extension pipe 1220 with the second cleaner module 1200 mounted
on the extension frame 1150.
[0042] Such a damper 1214 includes a damper section 1214a that is formed of an elastically
deformable material and opens/closes the channel. Thus, when the second fan motor
is not used, the damper section 1214a is kept closing the channel connected to the
extension pipe 1220. When the second fan motor is driven to generate the suction force,
the damper section 1214a is elastically deformed to open the channel by the suction
force generated from the second fan motor. Further, when the second fan motor is stopped
to generate no suction force, the damper section 1214a is elastically restored again
to close the channel.
[0043] Meanwhile, a rear face of the extension frame 1150 is provided with a seating recess
1150a on which the extension pipe 1220 is seated, and a lower portion of the extension
frame 1150 is provided with a catching recess 1150b on which a leading end (a lower
end of the extension pipe 1220 based on the drawings) of the extension pipe 1220 is
caught and supported. Thus, in a state in which the second cleaner module 1200 is
coupled to the extension frame 1150, the extension pipe 1220 is inserted into and
supported in the seating recess 1150a and the catching recess 1150b. Thereby, the
second cleaner module 1200 can be stably kept installed on the extension frame 1150
without arbitrary movement relative to the extension frame 1150. Further, in this
way, the extension pipe 1220 is installed on the extension frame 1150 through the
seating recess 1150a and the catching recess 1150b, so that an effect of reinforcing
strength of the extension frame 1150 due to the extension pipe 1220 can be achieved.
[0044] When the vacuum cleaner does cleaning in an upright mode, the dust is collected through
the first fan motor and the first dust collection unit 1130 included in the first
cleaner module 1100. When cleaning is done in a handheld mode, the dust is collected
through the second fan motor and the second dust collection unit 1230 included in
the second cleaner module 1200.
[0045] Thus, the first fan motor and the first dust collection unit 1130 are designed to
be able to suction a large quantity of air and to collect a large quantity of dust
at the sacrifice of weight. The second fan motor and the second dust collection unit
1230 are designed to suction a relative small quantity of air, to collect a relative
small quantity of dust, and to have a light weight. When used in the upright mode,
the vacuum cleaner may be designed to have a relatively high suction performance.
When used in the handheld mode in which the second cleaner module 1200 is separated
from the first cleaner module 1100, the user can hold and use the second cleaner module
1200 with ease.
[0046] Further, as described above, since the second cleaner module 1200 is removably installed
on the extension frame 1150, the user can displace the first cleaner module 1100 using
the handle 1211 provided for the second cleaner module 1200. In other words, the handle
1211 provided for the second cleaner module 1200 is used when cleaning is done in
the upright mode as well as when cleaning is done in the handheld mode.
[0047] Further, as illustrated in FIGS. 6 and 7, the extension frame 1150 has a protruding
male coupler 1150c, and the second body 1210 has a recessed female coupler 1210a into
which the male coupler 1150c is fitted, such that the second cleaner module 1200 is
removably coupled to the first cleaner module 1100.
[0048] Further, as described above, the second cleaner module 1200 has the extension cable
1240 and the plug 1250. Since power is supplied to the second cleaner module 1200,
the first cleaner module 1100 is supplied with the power via the second cleaner module
1200.
[0049] To this end, a plug module 1151 for electrical connection is disposed at the male
coupler 1150c, and a socket module 1212 is disposed in the female coupler 1210a.
[0050] Further, the female coupler 1210a is provided with a switch 1213 such that the power
is selectively applied to the socket module 1212 only when the male coupler 1150c
is coupled to the female coupler 1210a. The switch 1213 is pressed by a tip of the
male coupler 1150c, and is adapted to allow the power to be applied to the socket
module 1212.
[0051] Thus, as the male coupler 1150c is inserted into the female coupler 1210a, the plug
module 1151 is connected to the socket module 1212, and the power is applied to the
socket module 1212 by the switch 1213. Thus, the first cleaner module 1100 can be
supplied with the power from the second cleaner module 1200.
[0052] Further, an upper end of the extension frame 1150 is provided with a cover 1150d
that is formed away from the male coupler 1150c and encloses a part of the second
body 1210 adjacent to the female coupler 1210a when the male coupler 1150c is coupled
to the female coupler 1210a. Here, a guide rail 1150e is formed on an inner surface
of the cover 1150d so as to guide the second body 1210 entering along the cover, and
a guide groove 1210b is recessed in an outer surface of the second body 1210 adjacent
to the female coupler 1210a, so that the second body 1210 can accurately enter along
the cover 1150d. Thus, the plug module 1151 and the socket module 1212 can be accurately
coupled and connected.
[0053] As described above, the plug module 1151 is coupled to the socket module 1212, the
male coupler 1150c is fitted into the female coupler 1210a, and a part of the outer
surface of the second body 1210 adjacent to the female coupler 1210a is coupled inside
the cover 1150d. In other words, the second cleaner module 1200 is triply coupled
to the extension frame 1150 of the first cleaner module 1100, and thus the second
cleaner module 1200 can be stably kept installed on the extension frame 1150 of the
first cleaner module 1100.
[0054] In the present embodiment, the plug module 1151 and the socket module 1212 are provided
for the male coupler 1150c and the female coupler 1210a which are coupled with each
other, but embodiments of the invention are not limited thereto. The plug module 1151
and the socket module 1212 may be provided to be opposite to each other at other positions.
In detail, the plug module 1151 may be provided for the cover 1150d of the extension
frame 1150, and the socket module 1212 may be provided outside the female coupler
1210a of the second body 1210 so as to be opposite to the plug module 1151. Further,
the plug module 1151 may be provided for the extension frame 1150 so as to correspond
to the leading end of the extension pipe 1220 mounted on the extension frame 1150,
and the socket module 1212 may be provided for the leading end of the extension pipe
1220.
[0055] Further, in the present embodiment, the plug module 1151 is disposed at the male
coupler 1150c, and the socket module 1212 is disposed at the female coupler 1210a.
However, this is only an example. Conversely, the plug module may be disposed at the
female coupler, and the socket module may be disposed at the male coupler in other
embodiments.
[0056] Further, to allow the second cleaner module 1200 to be stably kept coupled to the
extension frame 1150 of the first cleaner module 1100, a structure for locking the
second cleaner module 1200 is installed on the extension frame 1150 as illustrated
in FIGS. 8 and 9.
[0057] The locking structure includes a locking member 1152 that is rotatably installed
on the extension frame 1150, an elastic member 1154 that elastically supports the
locking member 1152 and causes one end of the locking member 1152 to protrude from
the extension frame 1150 when the locking member 1152 is rotated in a first direction,
and a lever 1153 that is rotatably installed on the extension frame 1150 and is rotated
by a transmitted external force so as to rotate the locking member 1152 in a second
direction opposite to the first direction.
[0058] The lever 1153 includes a lever section 1153a that receives a force from a user such
that the lever 1153 can be rotated, and a pressing section 1153b that presses the
locking member 1152 by the rotation of the lever 1153 such that the locking member
is rotated in the second direction.
[0059] The locking member 1152 includes a locking section 1152a whose tip protrudes from
the extension frame 1150 to be locked in a locking recess 1210c formed in the second
cleaner module 1200, and an interlocking section 1152b that interacts with the pressing
section 1153b by the rotation of the lever 1153 such that the locking member 1152
is rotated in the second direction.
[0060] Accordingly, as illustrated in FIG. 9, in the state in which the second cleaner module
1200 is installed on the first cleaner module 1100, the locking member 1152 is elastically
supported in the first direction by an elastic restoration force of the elastic member
1154, and the tip of the locking section 1152a is kept locked in the locking recess
1210c. In this state, the user cannot separate the second cleaner module 1200 from
the first cleaner module 1100.
[0061] Further, as illustrated in FIG. 10, when the user applies a force to the lever section
1153a to rotate the lever 1153, the pressing section 1153b of the lever 1153 interacts
with the interlocking section 1152b of the locking member 1152 by the rotation of
the lever 1153, and rotates the locking member 1152 in the second direction. The tip
of the locking section 1152a is separated from the locking recess 1210c by the rotation
of the locking member 1152. In this state, the user can separate the second cleaner
module 1200 from the first cleaner module 1100.
[0062] In the present embodiment, the locking member 1152 is rotatably installed, and is
locked or unlocked by the rotation, which shows an example. As illustrated in FIGS.
11-13, the locking structure may include a locking member 1152' that is movably installed
on the extension frame 1150, an elastic member 1154' that elastically supports the
locking member 1152' such that the locking member 1152' moves in a first direction,
and a lever 1153' that is rotatably installed on the extension frame 1150, and is
rotated by a transmitted external force such that the locking member 1152' moves in
a second direction opposite to the first direction. As a user rotates the lever 1153',
the locking member 1152' may be locked or unlocked while moving.
[0063] In the present embodiment, the switch is a three-phase switch, and is adapted to
selectively supply power to any one of the first and second cleaner modules 1100 and
1200 depending on whether the second cleaner module 1200 is mounted or demounted,
but embodiments of the invention are not limited thereto. The switch may be a two-phase
switch, be adapted to selectively apply power to the second dust collection unit 1230
depending on whether or not the second cleaner module 1200 is separated. The power
may be applied to the first cleaner module 1100 by a separate button (not shown) provided
for the first cleaner module 1100.
[0064] In the present embodiment, the extension cable 1240 and the plug 1250 are connected
to the second cleaner module 1200 such that the first cleaner module 1100 is supplied
with the power via the second cleaner module 1200, but embodiments of the invention
are not limited thereto. The extension cable and the plug may be connected to the
first cleaner module 1100, and the second cleaner module 1200 may have a rechargeable
battery (not shown) housed therein.
[0065] In this case, the rechargeable battery housed in the second cleaner module 1200 is
charged when the second cleaner module 1200 is coupled to the first cleaner module
1100. After the second cleaner module 1200 is separated from the first cleaner module
1100, the rechargeable battery supplies power to the second cleaner module 1200 such
that the second cleaner module 1200 can be operated.
[0066] As discussed, embodiments can provide vacuum cleaner comprising: a first cleaner
module arranged to clean a floor in an upright mode; and a second cleaner module that
is removably coupled to the first cleaner module, wherein the second cleaner module
is arranged to be separated from the first cleaner module so as to enable cleaning

[0067] In some embodiments, the first fan motor is arranged to generate a suction force
greater than that of the second fan motor. In some such embodiments, the first fan
motor may be larger than the second fan motor.
[0068] In some embodiments, the first cleaner module includes a first body arranged to house
the first fan motor, a head unit that is disposed at a front side of the first body
and that is arranged to suction the air from the floor, and an extension frame connected
to the first body; and the second cleaner module is removably coupled to the extension
frame.
[0069] In some embodiments, one of the extension frame and second cleaner module includes
a protruding male coupler, and the other includes a female coupler to which the male
coupler is coupled. In some embodiments, one of the first and second cleaner modules
includes a plug module, and the other includes a socket module to which the plug module
is connected.
[0070] In some embodiments, the first cleaner module includes an upright connector formed

[0073] Although a few embodiments of the present disclosure have been shown and described,
it would be appreciated by those skilled in the art that changes may be made in these
embodiments without departing from the principles of the invention, the scope of which
is defined in the claims and their equivalents.
