DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0028] Exemplary embodiments of the present disclosure will be
described in detail with reference to the annexed drawings. In the
drawings, the same elements are denoted by the same reference
numerals throughout the drawings. In the following description,
detailed descriptions of known functions and configurations
incorporated herein have been omitted for conciseness and
clarity.
[0029] Hereinbelow, the preferred embodiments of the present
disclosure are described in detail with reference to accompanying
drawings. In the following description, a detailed description of
known functions and configurations incorporated herein will be
omitted when it may make the subject matter of the present
disclosure rather unclear.
[0030] FIG. 1 is a perspective view of a vacuum cleaner according
to an exemplary embodiment of the present disclosure.
[0031] The vacuum cleaner 10 according to the present embodiment
comprises a cleaner body 11, a suction brush 13, and a dust
collection unit 100.
[0032] The cleaner body 11 has a suction motor (not shown) as a
vacuum source, an inlet hose and an outlet hose (not shown), one
end of each of the inlet hose and the outlet hose is detachably
connected with the dust collection unit 100, wherein the
above-mentioned components are provided within the cleaner body 11.
In addition, a handle 15 is provided on the top of the cleaner body
11, so that a user can easily move the vacuum cleaner on a surface
to be cleaned.
[0033] The suction brush 13 is hinged to the bottom end of the
cleaner body 11 at the rear end thereof, and suctions dirt from a
surface to be cleaned through an inlet port (not shown) formed
through the bottom of the suction brush 13.
[0034] The dust collection unit 100 comprises a cyclone unit 110, a
dirt collection bin 120, a lever unit 130, an engagement unit 140
(see FIG. 2), a guide unit 150 (see FIGS. 3A and 4), and a gripping
means 160.
[0035] The cyclone unit 110 separates dirt from air suctioned from
a surface to be cleaned through the suction brush 13 and guided to
the inside of the cyclone unit 110 through the inlet hose (not
shown). In addition, the cyclone unit 110 discharges air purified
in this manner to the inlet hose (not shown). Such a cyclone unit
110 is removably arranged in the bin reception recess 12a (see FIG.
2) by fixing means (not shown).
[0036] The dirt collection bin 120 is arranged to communicate with
the bottom end of the cyclone unit 110 so that the dirt separated
from air by the cyclone unit 110 can drop, due to gravity and can
be collected in the dirt collection bin 120. The dirt collection
bin 120 has a central recess 124 which is inwardly depressed at the
center of the bottom surface of the dust collection bin 120, a
first cylindrical projection 125 formed at the center of the
central recess 124, and a pair of first inclined projections 126a
and 126b spaced from and surrounding the first cylindrical
projection 125. In addition, the dirt collection bin 124 also has a
limit groove 123 (see FIG. 4) for limiting the rotating angle of
the handle 133 (see FIG. 2) of the lever unit 133, the limit groove
123 being formed aside of the central recess 124.
[0037] As shown in FIG. 2, the lever unit 130 comprises a rotary
part 131, a handle 133, a second cylindrical projection 135, and a
pair of second inclined projections 137a and 137b. The rotary part
131 is rotatably inserted into the central recess 124 of the dirt
collection bin 120. The handle 133 is formed on a side portion of
the rotary part 131 and has a predetermined length so that a user
can grip the handle 133. The second cylindrical projection 135 is
formed at the center of the rotary part 131 and has a diameter
smaller than that of the first cylindrical projection 125, so that
the second cylindrical projection 135 is rotatably inserted into
the first cylindrical projection 125. The second inclined
projections 137a and 137b (see FIG. 2) are formed to be spaced from
and surround the second cylindrical projection 135, so that the
second inclined projections 137a and 137b (see FIG. 2) come into
slidable contact with the outer circumference of the second
cylindrical projection 135 while confronting with the first
inclined projections 126a and 126b (see FIG. 4). With such a lever
unit 130, when gripping and rotating the handle 133 in one
direction or the other direction by a predetermined angle, the
second inclined projections 137a and 137b, which rotate together
with the lever unit 130, come into slidable contact with the first
inclined projections 126a and 126b, thereby lifting or lowering the
dirt collection bin 120 by a height corresponding to the rotated
angle of the handle 133. In this manner, the lever unit 130 serves
to lift the dirt collection bin 120 so that the dirt collection bin
120 is compressed against the outer bottom surface of the cyclone
unit 110, and due to this action of the lever unit 130, air-tight
sealing is maintained between the cyclone unit 110 and the dirt
collection bin 120. As a result, the suction force within the dust
collection unit 100 is prevented from being reduced, and the
leakage of air or dirt from the dust collection unit is blocked,
whereby it is possible to prevent either the bin reception recess
12a in the cleaner body 11 or the surrounding of the vacuum cleaner
10 from being polluted by dirt leaking from the dust collection
unit 100.
[0038] The engagement unit 140 comprises an engagement groove 141
(see FIG. 2) formed in the bin reception recess 12a of the cleaner
body 11, and an engagement projection 145 snapped in the engagement
groove 141 (see FIG. 4). In this case, the engagement projection
145 is preferably formed of a synthetic resin so that it can be
resiliently engaged in the engagement groove 141. In addition, the
engagement groove 141 and the engagement 145 are mated with each
other at the both sides of each of them where they are in contact
with each other. That is, as shown in FIG. 3B, the engagement
groove 141 has depressions 143a and 143b vertically formed at the
opposite side walls thereof and the engagement projection 145 has
protrusions 146a and 146b formed at opposite side edges on the
front face thereof, so that the protrusions 146a and 146b are
inserted into the depressions 143a and 143b, respectively, when the
engagement projection 145 is snapped in the engagement groove 141,
wherein the protrusions 146a and 146b are vertically formed to
correspond with the depressions 143a and 143b, respectively. In
addition, the protrusions 146a and 146b are formed to be somewhat
larger than the depressions 143a and 143b in volume, so that the
former is press-fitted into the latter, whereby solid engagement
can be achieved. Furthermore, the engagement projection 145 has a
height less than that of the engagement groove 141, so that when
the engagement projection 145 is snapped into the engagement groove
141, a gap (G) is formed between the top wall 143c of the
engagement groove 141 and the top surface 146c of the engagement
projection 145, as shown in FIG. 7B, thereby assuring that upon
being lifted by rotary part 131, the dirt collection bin 120 is
engaged with the outer bottom surface of the cyclone unit 110 at
the top end thereof while maintaining an airtight condition. More
specifically, as shown in FIG. 6, the height of the engagement
groove 141, H1, is larger than the height of the engagement
projection 145, H2 (i.e., H1>H2), wherein the gap G is provided
in order that when the dirt collection bin 120 is lifted from a
state in which it is fixed in the bin reception recess 12a by the
engagement unit 140, the dirt collection bin 120 can be lifted with
a horizontal posture without being inclined toward the fixed side
in such a manner as to be engaged with the outer bottom surface of
the cyclone unit 110 while maintaining the airtight condition. As a
result, the dirt collection bin 120 is stably and smoothly lifted
and lowered while being retained within the bin reception recess
12a by the rotation of the lever unit 130.
[0039] The guide unit 150 comprises a pair of guide grooves 153a
and 153b (see FIG. 4) formed longitudinally parallel to each other
on the outer bottom surface of the dirt collection bin 120, and a
pair of guide projection 151a and 151b formed on the seating
surface 12b (see FIG. 3A), on which the outer bottom surface of the
dirt collection bin 120 is seated, in such a manner that the guide
projections 151a and 151b are correspondingly inserted into the
guide grooves 153a and 153b. Such a guide unit 150 serves to guide
the dust collection unit 100 in such a manner that when the dust
collection unit 100 is inserted into the bin reception recess 12a
of the cleaner body 11, the engagement projection 145 is correctly
engaged in the engagement groove 141, whereby a user can easily
make the engagement groove 141 and the engagement projection 145
engaged with each other. Meanwhile, according to an exemplary
embodiment of the present disclosure, the leftward and rightward
rotation of the dirt collection bin 120 is restrained through the
guide unit 150, and the forward and backward movement of the dirt
collection bin 120 is restrained through the engagement unit 140,
as a result of which the dirt collection bin 120 can be
three-dimensionally fixed at a side portion and the bottom side
thereof.
[0040] The gripping means 160 is provided on a side portion of the
dirt collection bin 120 exposed to the outside in a state in which
the dirt collection bin 120 is received in the bin reception recess
12a in the cleaner body 11, so that a user can easily and
conveniently pull out the dirt collection bin 120 from the bin
reception recess 12a to the outside using one or more fingers.
[0041] Now, description is made in relation to how to mount the
dirt collection bin configured according to the exemplary
embodiment of the present disclosure as described above.
[0042] When a user mounts the dirt collection bin 120 below the
cyclone unit 110 fixed in the bin reception recess 12a in the
cleaner body 11, the user grips the gripping means 160 of the dirt
collection bin 160 (see FIG. 2) and then pushes the dirt collection
bin 120 into a space below the cyclone unit 110 in the cleaner body
11 in such a manner that the guide grooves 153a and 153b (see FIG.
4) formed on the bottom of the dirt collection bin 120 are engaged
with the guide projections 151a and 151b (see FIG. 3A) formed on
the seating surface 12b (see FIG. 3A) in the cleaner body 11.
[0043] The user pushes the dirt collection bin 120 into the space
until the engagement projection 145 is snapped in the engagement
groove 141 so that the predetermined gap G is provided between the
engagement projection 145 and the engagement groove 141 as shown in
FIG. 7B. From this state, the handle 133 of the lever unit 130 is
rotated to a point B as shown in FIG. 8A from the initial position
(point A) thereof.
[0044] As a result, the dirt collection bin 120 is lifted toward
the outer bottom surface of the cyclone unit 110 by the first and
second inclined projections 126a and 126b; 137a and 137b which are
in slidable contact with each other between the dirt collection bin
120 and the lever unit 110. At this time, the engagement projection
145 is vertically lifted in the engagement groove 141 together with
the dirt collection bin 120, so that the top surface 146c of the
engagement projection 145 comes into contact with the top wall 143c
of the engagement groove 141. Therefore, the dirt collection bin
120 is lifted while maintaining its horizontal posture, so that the
dirt collection bin 120 is safely received in the space below the
cyclone unit 110 in a compressed state against the outer bottom
surface of the latter, whereby the top end of the dirt collection
bin 120 is evenly in contact with the outer bottom surface of the
cyclone unit 110 in general, whereby the airtight condition can be
maintained between the cyclone unit 110 and the dirt collection bin
120.
[0045] At this time, in order to prevent the dirt collection bin
120 from being released from the bin collection part 12a in the
cleaner body when the guide projections 151a and 151b are
disengaged from the guide grooves 153a and 153b after the dirt
collection groove 120 is lifted, it is desired that the height of
the guide projections 151a and 151b and the depth of the guide
grooves 153a and 153b are larger than the maximum height for
allowing the dirt collection bin 120 to be lifted.
[0046] When the dirt collection bin 120 is separated from the bin
reception recess 12a in order to remove the dirt collected in the
dirt collection bin 120, the handle 133 of the lever unit 130 is
rotated from the point B (see FIG. 8B) to the point A (see FIG.
7A). As such, the dirt collection bin 120 will be lowered in the
reversed sequence as compared with the procedure of mounting the
dirt collection bin 120. In this state, if the gripping means 160
is gripped and pulled in the direction opposite to that for
mounting the dirt collection bin 120, i.e., to the outside of the
cleaner body 11, the snapped engagement between the engagement
groove 141 and the engagement projection 145 is released so that
the dirt collection bin 120 can be easily pulled out from the
cleaner body 11.
[0047] According to the present disclosure as described above,
there is an advantage in that the dirt collection bin can be simply
and stably snapped in the bin collection part in the cleaner body
through a simple engagement unit. In addition, convenience in use
can be enhanced because the dirt collection bin can be simply
separated from the bin-reception recess in the cleaner body by
drawing the dirt collection means from the cleaner body in a
predetermined direction for pulling out the dirt collection
bin.
[0048] Moreover, when the dirt collection bin is lifted through the
lever unit, the dirt collection bin is lifted while maintaining the
horizontal posture thereof through the engagement unit and the
guide unit, so that the top end of the dirt collection bin
generally comes into contact with the outer bottom surface of the
cyclone unit in an evenly compressed state, whereby the airtight
state can be maintained between the cyclone unit and the dirt
collection bin.
[0049] Although representative 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.
