DETAILED DESCRIPTION OF THE EXEMPLARY EMBODIMENTS
[0021] Certain embodiments of the present invention will be
described in greater detail with reference to the accompanying
drawings.
[0022] In the following description, same drawing reference
numerals are used for the same elements even in different drawings.
The matters defined in the description such as a detailed
construction and elements are nothing but the ones provided to
assist in a comprehensive understanding of the invention. Thus, it
is apparent that the present invention can be carried out without
those defined matters. Also, well-known functions or constructions
are not described in detail since they would obscure the invention
in unnecessary detail.
[0023] Referring to FIG. 1, a vacuum cleaner 100 having a suction
port assembly 200 according to an embodiment of the present
invention includes a cleaner body 110 housing a contaminant chamber
(not shown) and a vacuum source (not shown), an operation part 130
for operating the vacuum cleaner 100, a suction port assembly 200
drawing in contaminant-laden air from the surface being cleaned by
use of suction force generated from the vacuum cleaner (not shown),
a flexible hose 120 connecting the cleaner body 110 with the
operation part 130, and an extension pipe 140 connecting the
operation part 130 with the suction port assembly 200.
[0024] Referring to FIGS. 1 and 2, the suction port assembly 200
includes a body comprising a first assembly body 210 and a second
assembly body 220.
[0025] The first assembly body 210 cleans the first cleaning
surface 10. To this end, the first assembly body 210 has a suction
path 213 defined at the upper end, and a first suction hole 212
defined at the lower surface of the first assembly body 210
contacting or in proximity to the first cleaning surface 10.
[0026] The suction path 213 is formed of a cylindrical pipe which
may be formed integrally with or separately from the first assembly
body 210. The extension pipe 140 is coupled to or in fluid
communication with the suction path 213.
[0027] The first suction hole 212 may be formed to be a rectangular
opening which is extended to the right open side 210a of the first
assembly body 210. The first suction hole 212 directly contacts
with or is in proximity to the first cleaning surface 10, and the
contaminant-laden air is drawn through the first suction hole 212
from the first cleaning surface 10. A plurality of cleaning
bristles 250 may be attached along the outer part of the first
suction hole 212 to hit and scratch contaminants off from the first
cleaning surface 10. The first suction hole 212 may take a variety
of alternative configurations such as, for example, cylinders and
ellipses.
[0028] The second assembly body 220 cleans the second cleaning
surface 20 which is at a predetermined angle .theta.1 with respect
to the first cleaning surface. To this end, there is a second
suction hole 222 defined at the lower side of the second assembly
body 220. The first and second cleaning surfaces 10, 20 form a
non-linear cleaning surface.
[0029] The second suction hole 222 is a substantially rectangular
opening which extends to the left open side 220a of the second
assembly body 220, and contacts directly or is in proximity with
the second cleaning surface 20. Accordingly, the contaminant-laden
air is drawn in through the second suction hole 222 from the second
cleaning surface 20. There are a plurality of cleaning bristles 250
attached along the outside of the second suction hole 222 to hit
and scratch contaminants off from the second cleaning surface 20.
The second suction hole 222 may take a variety of alternative
configuration, such as, for example, cylinders and ellipsis.
[0030] The first and the second suction holes 212 and 222 are
interconnected with the suction path 213. More specifically, the
first suction hole 212 is located in the first assembly body 210,
so that the first suction hole 212 directly interconnects with the
suction path 213.
[0031] Because the first suction hole 212 is extended to the right
open side 210a of the first assembly body 210, and the second
suction hole 222 is extended to the left open side 220a of the
second assembly body 220, the second suction hole 222 is indirectly
interconnected with the suction path 213, that is connected via the
first suction hole 212.
[0032] According to the construction as described above,
contaminants of the first cleaning surface 10 are drawn through the
suction path 213 via the first suction hole 212, while the
contaminants of the second cleaning surface 20 are drawn to the
suction path 213 via the second and the first suction holes 222 and
212.
[0033] Referring to FIG. 2, the second assembly body 220 for
cleaning the second cleaning surface 20, is articulately connected
to be rotatable with respect to the first assembly body 210. To
this end, the first assembly body 210 includes a hinge groove 211,
and the second assembly body 220 includes a hinge protrusion 221
for advancement into the hinge groove 211. Additionally, a hinge
pin 230 to engage the hinge groove 211 and the hinge protrusion 221
is used, and an elastic member 240 is disposed on the hinge pin
230.
[0034] In order to define the hinge groove 211, there are two
supports 211a and 211b at the upper right side of the first
assembly body 210. The supports 211a and 211b each include a
piercing hole for the hinge pin 230 to pass therethrough, and can
be formed integrally with, or separately from, the first assembly
body 210.
[0035] The hinge protrusion 221 for advancement into the hinge
groove 211, may be formed integrally with, or separately from, the
upper left side of the second assembly body 220, and has a piercing
for the hinge pin 230 to pass therethrough.
[0036] The hinge pin 230 serves as an axis on which the hinge
protrusion 221 is rotatably engaged with the hinge groove 211. The
hinge pin 230 is passed through the piercing holes of the supports
211a and 211b and then through the piercing hole of the hinge
protrusion 221.
[0037] The elastic member 240, such as, for example, a coil spring
or other biasing device, may be disposed on or operably connected
with the hinge pin 230. The elastic member 240 may be disposed to
urge the second assembly body 220 in the direction indicated by
arrow B (see FIG. 1). Accordingly, when both of the first and the
second cleaning surfaces 10 and 20 are planar to each other such
that both are positioned at an angle .theta.1 of zero degrees with
respect to each other, by the urging force of the elastic member
240, the interior angle .theta.2 between the first and the second
assembly bodies 210 and 220 is automatically turned to 180 degree,
and therefore, the second assembly body 220 is turned horizontal
with respect to the first assembly body 210. When the interior
angle .theta.2 becomes zero degrees, the second assembly body 220
is folded onto the first assembly body 210.
[0038] With the engagement structure of the first and the second
assembly bodies 210 and 220 as described above, the user of the
vacuum cleaner can clean both of the first cleaning surface 10 and
the second slanted cleaning surface 20 in one cleaning operation or
simultaneously. The cleaning method according to the present
invention will be described hereinbelow in greater detail.
[0039] Referring to FIG. 1, when the slope angle .theta.1 of the
second cleaning surface 20 with respect to the first cleaning
surface 10 is large, the user of the cleaner pushes the extension
pipe 140 in the direction indicated by arrow F1, and advances the
suction port assembly 200 in the direction indicated by arrow F2.
In such a situation, as the second assembly body 220 is moved by
the pushing force of the user in the direction indicated by arrow
A, the interior angle .theta.2 decreases.
[0040] When the angle .theta.1 of the second cleaning surface 20
with respect to the first cleaning surface 10 is small, the user
pulls the extension pipe 140 in the direction indicated by arrow
F3, and therefore, retreats the first assembly body 210 in the
direction indicated by arrow F4. In such a situation, as the second
assembly body 220 is moved by the urging force of the elastic
member 240 in the direction indicated by the arrow FB, the interior
angle .theta.2 increases.
[0041] According to the increase and decrease of the slope angle
.theta.1, the interior angle .theta.2 between the first and the
second assembly bodies 210 and 220 is varied, and according to the
variance of the interior angle .theta.2, the first assembly body
210 may be brought into tight contact with the first cleaning
surface 10, or the second assembly body 220 may be brought into
tight contact with the second cleaning surface 20. Accordingly,
suction efficiency deterioration of the cleaning is prevented, and
damage to the suction port assembly 200 due to collision with the
cleaning surfaces 10 and 20 can also be avoided.
[0042] The operation of the suction port assembly 200 as shown in
FIG. 1 will now be described in greater detail.
[0043] Referring to FIGS. 1 and 2, the user varies the interior
angle .theta.2 in accordance with the slope angle .theta.1, to
clean the cleaning surfaces 10 and 20 in one cleaning operation.
More specifically, the user pushes the extension pipe 140 in the
direction indicated by arrow F1. Accordingly, the first assembly
body 210 contacts with the first cleaning surface 10, and advances
in the direction of arrow F2, while the second assembly body 220 is
turned in the direction of arrow A, and contacts with the second
cleaning surface 20. In a state that the first assembly body 210
contacts the first cleaning surface 10, and the second assembly
body 220 contacts the second cleaning surface 20, the suction port
assembly 200 is moved in the direction either of arrow E or arrow
F, to clean the first and the second cleaning surfaces 10 and
20.
[0044] During operation, the bristles 250 along the outer side of
the first suction hole 212 hits and scratch the contaminants off
from the first cleaning surface 10, so that the contaminants can be
drawn to the suction path 213 via the first suction hole 212 which
is defined at the lower side of the first assembly body 210.
[0045] At the same time, the bristles 250 formed along the outer
side of the second suction hole 222 hit and scratch contaminants
off from the second cleaning surface 20, so that the contaminants
can be drawn into the suction path 213 via the second suction hole
222 which is defined at the lower side of the second assembly body
220, and the first suction hole 212 interconnected with the second
suction hole 222.
[0046] After that, the contaminants at the suction path 213 are
collected in the dust chamber (not shown) of the cleaner body 110
via the extension pipe 140 and the flexible hose 120.
[0047] Meanwhile, the suction port assembly 300 may be structured
for the stairway cleaning purpose, as shown in FIG. 3. A reference
numeral 400 denotes a carpet covering the stairway 300.
[0048] When constructed for stairway cleaning purpose, the suction
port assembly 300 has the first and the second assembly bodies 310
and 320 at the interior angle .theta.4 constantly more than 60
degrees. More preferably, the interior angle .theta.4 may be fixed
to 90 degrees. To this end, the right open corner 310a (see FIG. 4)
of the first assembly body 310 and the left open corner 320b (see
FIG. 4) of the second assembly body 320 are contacted with each
other to provide for direct communication of the suction
therebetween. By fixing the interior angle .theta.4 to 90 degrees,
the slope angle .theta.3 between the first and the second cleaning
surfaces 30 and 40 can be maintained at 90 degrees, and therefore,
the interior angle .theta.4 does not change in operation.
Furthermore, by doing as described above, the elastic member 240
(see FIG. 2) may be omitted from the suction port assembly 300 for
the stairway cleaning operation, because the interior angle
.theta.4 is not required to be automatically adjusted.
[0049] In addition, if the interior angle .theta.4 is fixed to a
limit of 90 degrees, the suction port assembly 300 can be stowed
with increased convenience when not in use, because the second
assembly body 320 can be turned 90 degrees toward the first
assembly body 310 so that the second assembly 320 can be folded
onto the first assembly body 310. The top of the second assembly
320 is preferably adapted with a recess so as to allow for the
folding of the second assembly completely over the first assembly
310 as shown in FIG. 4. The other structures will not be explained
hereinbelow for these are similar to those of the suction port
assembly 200 as described above with reference to FIG. 1.
[0050] The operation of the suction port assembly 300 of FIG. 3
will now be described in greater detail below.
[0051] Referring to FIG. 3, the user of the cleaner contacts the
first assembly body 310 to the first cleaning surface 30, and the
second assembly body 320 to the second cleaning surface 40,
respectively. Unlike the structure of the suction port assembly as
shown in FIGS. 1 and 2, because the slope angle .theta.3 and the
interior angle .theta.4 are fixed to 90 degrees, the user does not
need to force the extension pipe 140 to vary the interior angle
.theta.4 in accordance with the slope angle .theta.3.
[0052] With the first assembly body 310 contacting the first
cleaning surface 30 and the second assembly body 320 contacting the
second cleaning surface 40, the suction port assembly 300 is moved
in the direction of arrow G or arrow H, and cleans the first and
the second cleaning surfaces 30 and 40. The rest of the cleaning
operation will be omitted for this is similar to that which has
been described above with reference to FIGS. 1 and 2.
[0053] With the suction port assembly of a vacuum cleaner as
explained so far, the operator of the cleaner can clean the
cleaning surfaces even with slopes, with maintained suction
efficiency. Further, damage to suction port assembly due to
collision with the cleaning surface, can be avoided.
[0054] The vacuum cleaner having a suction port assembly according
to the present invention is especially effective for the cleaning
of stairways with slope angles of 90 degrees, or carpeted areas
which attract more dusts and therefore require frequent cleaning
operations.
[0055] The foregoing embodiment and advantages are merely exemplary
and are not to be construed as limiting the present invention. The
present teaching can be readily applied to other types of
apparatuses. Also, the description of the embodiments of the
present invention is intended to be illustrative, and not to limit
the scope of the claims, and many alternatives, modifications, and
variations will be apparent to those skilled in the art.
