DETAILED DESCRIPTION
[0040] 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.
[0041] FIG. 1 is a perspective view for describing an exterior of a
vacuum cleaning device according to an embodiment of the present
disclosure. FIG. 2 is a side cross-sectional view for describing a
main configuration of the vacuum cleaning device illustrated in
FIG. 1. FIG. 3 is a side view of the vacuum cleaning device of FIG.
1. FIG. 4 illustrates wheels and a discharge port of the vacuum
cleaning device of FIG. 1.
[0042] Referring to FIGS. 1 through 4, a vacuum cleaning device 1
according to an embodiment of the present disclosure includes a
body 10 and an extension pipe assembly 50 that is rotatably coupled
to the body 10.
[0043] The body 10 may be formed by assembling an upper body 20 and
a lower body 40. The upper body 20 and the lower body 40 may be
coupled to each other so as to be moved forward and backward. That
is, the body 10 may be extended in a lengthwise direction or may be
compressed. Although not shown in the drawing, the body 10 includes
an elastic member (not shown) that elastically supports the upper
body 20 and the lower body 40 so as to be spaced apart from each
other by a predetermined gap. The body 10 may be provided so that
the upper body 20 and the lower body 40 are close to each other and
then are restored to their original positions due to an elastic
force of the elastic member.
[0044] Since, in this way, the body 10 may be extended and
compressed, usage conveniences of the vacuum cleaning device 1 can
be increased. This will be described later.
[0045] A fan motor 22 that generates an inhalation force and a dust
collecting unit 21 that removes and collects dust from air inhaled
by the inhalation force generated by the fan motor 22 may be
disposed at the upper body 20. However, the fan motor 22 and the
dust collecting unit 21 do not need to be disposed at the upper
body 20 and may be disposed at the lower body 40, unlike the
current embodiment.
[0046] An air cleaning unit 45 that may collect dust from air
purified by the dust collecting unit 21 again may be disposed on a
lower flow path of the dust collecting unit 21. The air cleaning
unit 45 may include a sterilizing unit using atmospheric pressure
plasma.
[0047] A wheel mounting portion 41 on which wheels 42 for driving
the body 10 are mounted, may be disposed at a lower end of the
lower body 40. The wheel mounting portion 41 may have a shape of a
ring having an approximately middle portion that is perforated. The
wheels 42 may be rotatably mounted on an approximately outer side
of the wheel mounting portion 41 along a circumferential direction
of the wheel mounting portion 41.
[0048] A discharge port 43 through which purified air after passing
through the dust collecting unit 21 and the air cleaning unit 45 is
discharged indoors again, may be disposed at an inner side of the
wheel mounting portion 41.
[0049] The extension pipe assembly 50 may include an inhalation
nozzle 60 that inhales air, an extension pipe 70 that is coupled to
the inhalation nozzle 60 and guides air, a connection pipe 80 for
combining the extension pipe assembly 50 and the body 10, and a
handle 100 for user's manipulation.
[0050] The extension pipe 70 may be a pipe having rigidity, and a
path (not shown) on which air is guided, may be formed in the
extension pipe 70. The inhalation nozzle 60 and the extension pipe
70 may be coupled to each other so as to be rotatable with respect
to each other.
[0051] The connection pipe 80 has a path (not shown) which is
formed in the connection pipe 80 and on which air is guided. The
connection pipe 80 is coupled to the extension pipe 70 and the body
10. The extension pipe 70 and the connection pipe 80 may be formed
integrally with each other or may be separately formed and
assembled.
[0052] The extension pipe assembly 50 and the body 10 may be
rotatably coupled to each other using hinge portions 30 and 90.
Thus, the vacuum cleaning device 1 has a shape with like two legs,
and a load of the body 10 and a load of the extension pipe assembly
50 may be dispersed into the wheels 42 of the body 10 and the
inhalation nozzle 60 of the extension pipe assembly 50 and may be
supported on the ground.
[0053] Thus, the user is not required to devote his energies to
bear out the weight of the vacuum cleaning device 1 except for a
manipulation force used to manipulate the handle 100 so as to
select a position of the inhalation nozzle 60. Thus, the user's
usage conveniences can be increased.
[0054] Also, the hinge portions 30 and 90 of the vacuum cleaning
device 1 according to the current embodiment of the present
disclosure include a guide flow path on which air of the extension
pipe assembly 50 is guided toward the body 10. Thus, the exterior
of the vacuum cleaning device 1 is simplified, and there are no
disturbances during a cleaning operation so that usage conveniences
can be increased.
[0055] FIG. 5 is an exploded perspective view for describing a
combined structure of an extension pipe assembly and a body of the
vacuum cleaning device of FIG. 1, according to an embodiment of the
present disclosure. FIG. 6 is a plan view of the vacuum cleaning
device of FIG. 1. FIG. 7 is a cross-sectional view of portion `A`
of FIG. 6 for describing the combined structure of the extension
pipe assembly and the body of the vacuum cleaning device of FIG. 1.
FIG. 8 is a cross-sectional view for describing a combined
structure of the extension pipe assembly and the body of the vacuum
cleaning device of FIG. 1, according to another embodiment of the
present disclosure
[0056] The hinge portions 30 and 90 that rotatably couple the
extension pipe assembly 50 and the body 10 to each other may
include a body hinge portion 30 disposed at the body 10 and an
extension pipe hinge portion 90 disposed at the extension pipe
assembly 50.
[0057] Each of the body hinge portion 30 and the extension pipe
hinge portion 90 may have an approximately cylindrical shape. The
body hinge portion 30 and the extension pipe hinge portion 90 may
be disposed adjacent to each other in an axial direction.
[0058] The extension pipe hinge portion 90 may include a hinge
shaft portion 91 that protrudes in the axial direction, and the
body hinge portion 30 may include a hinge shaft accommodation
portion 31 in which the hinge shaft portion 91 is accommodated.
Thus, the hinge shaft portion 91 is inserted into the hinge shaft
accommodation portion 31 so that the extension pipe hinge portion
90 and the body hinge portion 30 can be rotatably coupled to each
other.
[0059] However, it is just one example that the hinge shaft portion
91 is disposed at the extension pipe hinge portion 90 and the hinge
shaft accommodation portion 31 is disposed at the body hinge
portion 30. Embodiments of the present disclosure are not limited
thereto, and the hinge shaft portion 91 may be disposed at the body
hinge portion 30, and the hinge shaft accommodation portion 31 may
be disposed at the extension pipe hinge portion 90.
[0060] Support members 121 and 122 that support the extension pipe
hinge portion 90 and the body hinge portion 30 so that the
extension pipe hinge portion 90 and the body hinge portion 30 are
not detached from the body 10, may be disposed at an outer side of
the extension pipe hinge portion 90 and at an outer side of the
body hinge portion 30. The support member 121 may be fixed to the
connection pipe 80, and the support member 122 may be fixed to the
upper body 20.
[0061] The vacuum cleaning device 1 may have a connection hose 110
that guides air of the extension pipe assembly 50 toward the body
10. The connection hose 110 may be provided to pass through the
extension pipe hinge portion 90 and to be connected to the body 10,
i.e., the upper body 20.
[0062] To this end, the extension pipe hinge portion 90 may include
a hose accommodation portion 92 that accommodates the connection
hose 110 and a drawing port 95 that is formed on a circumferential
surface of the extension pipe hinge portion 90 so that the
connection hose 110 can be drawn from the hose accommodation
portion 92.
[0063] Also, an insertion port 23 through which the connection hose
110 is inserted into a curved surface corresponding to the
circumferential surface of the extension pipe hinge portion 90 may
be formed at the body 10, i.e., the upper body 20.
[0064] Through this configuration, air of the extension pipe
assembly 50 may be guided toward the body 10 via the extension pipe
hinge portion 90.
[0065] As another embodiment in which air of the extension pipe
assembly 50 flows into the body 10 via the hinge portions 30 and
90, as illustrated in FIG. 8, a first channel 296 that guides air
may be disposed at an extension pipe hinge portion 290, and a
second channel 236 that communicates with the first channel 296 may
be disposed at a body hinge portion 230.
[0066] In this case, the first channel 296 and the second channel
236 may communicate with each other using a shaft coupling portion
of the extension pipe hinge portion 290 and the body hinge portion
230. Here, the shaft coupling portion means a hinge shaft portion
291 of the extension pipe hinge portion 290 and a hinge shaft
accommodation portion 231 of the body hinge portion 230.
[0067] That is, an outlet 297 of the first channel 296 may be
formed at the hinge shaft portion 291, and an inlet 237 of the
second channel 236 may be formed at the hinge shaft accommodation
portion 231.
[0068] Through this structure, even when the hinge shaft portion
291 and the hinge shaft accommodation portion 231 are rotated, the
first channel 296 and the second channel 236 communicate with each
other without any change so that air and dust of the extension pipe
assembly 50 can smoothly flow into the body 10.
[0069] FIGS. 9 and 10 are views for describing an operation of the
vacuum cleaning device of FIG. 1. The operation of the vacuum
cleaning device according to an embodiment of the present
disclosure will be described with reference to FIGS. 9 and 10.
[0070] The extension pipe assembly 50 and the body 10 of the vacuum
cleaning device 1 may be rotated with respect to each other so that
an angle .theta. between the extension pipe assembly 50 and the
body 10 varies between a minimum angle .theta.1 and a maximum angle
.theta.2.
[0071] The angle .theta. becomes the minimum angle .theta.1 while
the vacuum cleaning device 1 is kept, so that an area of the vacuum
cleaning device 1 can be minimized.
[0072] When the vacuum cleaning device 1 is being used, the
extension pipe assembly 50 and the body 10 may be rotated with
respect to each other so that the angle .theta. is repeatedly
increased or decreased between the minimum angle .theta.1 and the
maximum angle .theta.2.
[0073] In particular, when the user wants to move the inhalation
nozzle 60 forward, the user has only to press the handle 100 from
upward to downward in a direction of gravity so that the user can
move the inhalation nozzle 60 forward using a small force.
[0074] Also, when the user wants to move the inhalation nozzle 60
backward, the user exerts the manipulation force on the handle 100
so that the body 10 is extended due to the elastic force of the
elastic member (not shown) disposed at the body 10, the angle
.theta. is decreased and the inhalation nozzle 60 can be moved
backward. Thus, the user can move the inhalation nozzle 60 backward
using a small force.
[0075] As described above, according to the idea of the present
disclosure, a load of a body including a dust collecting unit and a
fan motor and a load of an extension pipe assembly including an
inhalation nozzle and an extension pipe are dispersed into wheels
of the body and the inhalation nozzle of the extension pipe
assembly and are supported on the ground so that no burden
resulting from the weight of the vacuum cleaning device is applied
to a user and usage conveniences are improved.
[0076] In addition, this structure is simple and has a
discriminative design so that an aesthetic sense can be
improved.
[0077] 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 and spirit of the disclosure, the
scope of which is defined in the claims and their equivalents.
