DETAILED DESCRIPTION OF THE EXEMPLARY EMBODIMENTS
[0020] The matters defined in the description such as a detailed
construction and elements are provided to assist in a comprehensive
understanding of the exemplary embodiments of the disclosure and
are merely exemplary. Accordingly, those of ordinary skill in the
art will recognize that various changes and modifications of the
exemplary embodiments described herein can be made without
departing from the scope and spirit of the disclosure. Also,
descriptions of well-known functions and constructions are omitted
for clarity and conciseness.
[0021] Hereinafter, certain exemplary embodiments of the present
disclosure will be described in detail with reference to the
accompanying drawing figures.
[0022] FIG. 1 to FIG. 3 are figures related to a first embodiment
of a vacuum cleaner according to the present disclosure, where FIG.
1 is a perspective view showing a main body detached from a cleaner
frame, FIG. 2 is a bottom view of the main body, and FIG. 3 is a
perspective view showing the use of the vacuum cleaner 1 of FIG.
2.
[0023] Referring to FIG. 1, a vacuum cleaner 1 in accordance with
one embodiment of the present disclosure includes a main body 20, a
cleaner frame 10, a main brush assembly 13, a flexible hose 49, an
extending pipe 30, and an auxiliary brush assembly 31. The main
body 20 can be mounted detachably to cleaner frame 10.
[0024] The main body 20 is provided with a dust collector 21, a
motor chamber 25 installed with a suction motor (not shown), a
telescopic handle 28, traveling wheels 26a and 26b, and a support
member 27. The dust collector 21 is configured with a cyclone
chamber 22 and a dust canister 23, with the dust canister 23 being
mounted detachably to the main body 20. The motor chamber 25 is
provided at a lower end of the dust canister 23 and has a suction
motor (not shown) therein, and the suction motor transfers suction
power through the dust collector 21 to the main brush assembly 13
or the auxiliary brush assembly 31.
[0025] The telescopic handle 28 is installed on a top of a frame 42
of the main body, and length thereof is adjustable in an up/down
direction so that a user can adjust the height of the telescopic
handle 28 to agree with his or her stature (see FIG. 3). Traveling
wheels 26a and 26b help moving of the main body 20 and each one
thereof is installed at both sides of a lower end of the frame 42
of the main body 20 as shown in FIG. 1 and FIG. 2. The support
member 27 is projected downward with a slight slope from a lower
end of the motor chamber 25, so that the main body 20 is stood
upright and does not fall down in the case of the main body 20
being stood on a floor. Thus, a user may move the main body 20 by
slightly inclining it toward a side where the traveling wheels 26a
and 26b exist after extending the telescopic handle 28 to agree
with his/her stature, and in a place to be cleaned the user may
clean there by holding the extending pipe 30 after standing up the
main body 20 to make the support member 27 of the main body to come
in contact with a floor so as to prevent the main body 20 from
moving.
[0026] The cleaner frame 10, as shown in FIG. 1, is formed with a
mounting space 11 in which the main body 20 is removably mounted.
The cleaner frame 10 is configured with a hand grip 15, a base
plate 19, and two columns 8 and 9. At a lower end of the two
columns 8 and 9 are mounted, respectively, main wheels 18. The hand
grip 15 is integrally configured on an upper portion of the two
columns 8 and 9, and the two columns 8 and 9 are separated from
each other at a predetermined space thereby the mounting space 11
for mounting the main body 20 therebetween. The base plate 19 is
configured to support a lower surface of the main body 20 and is
provided integrally in a lower portion of the mounting space 11,
i.e. between the two columns 8 and 9 at a lower portion where the
two columns terminate.
[0027] In the base plate 19 there are formed, respectively, a
recess groove 17 in which the support member 27 is inserted and two
wheel inserting grooves 16a and 16b in which the traveling wheels
26a and 26b are inserted. Main body 20 includes an inlet 43 (see
FIG. 1) of an air passage, which delivers external air flowing
through the main brush assembly 13 to the main body 20 and the
inlet is in tight contact with an air inlet 45 (see FIG. 2) formed
at a lower surface of the main body 20. At an inside surface of the
two columns 8 and 9 are installed, respectively, two locking
members 47. Thus, once the main body 20 of the vacuum cleaner 1 is
mounted into the mounting space 11, the main body 20 is not easily
separated from the cleaner frame 10 due to the locking members
47.
[0028] The main brush assembly 13 is connected to the base plate 19
of the cleaner frame 10. The main brush assembly 13 comes in
contact with a surface to be cleaned and external air flows through
the main brush assembly 13 into the main body 20.
[0029] Referring to FIG. 1, the flexible hose 49 is connected to a
rear surface of the main body 20 and communicates with the dust
collector 21. In addition, the flexible hose 49 is connected to the
auxiliary brush assembly 31 through the extending pipe 30. Thus,
external air flows in the auxiliary brush assembly 31, through the
extending hose 30, and through the flexible hose 49 into the dust
collector 21.
[0030] A cleaning operation by using the vacuum cleaner 1 in
accordance with the above embodiment will be described hereinafter
with reference to FIG. 1 to FIG. 3.
[0031] In FIG. 1, vacuum cleaner 1 can be used as an up-right type
cleaner by inserting the main body 20 into the mounting space 11 so
that the lower surface of the main body 20 is in contact with the
base plate 19 of the cleaner frame 10 and both sides of the main
body frame 42 are locked by the locking members 47. By gripping the
hand grip 15 and inclining the cleaner frame 10 and the main body
20 rearward, the main brush assembly 13 and the air passage of the
main body 20 are communicated with each other and external air
flows through the main brush assembly 13 into the main body 20 so
that dust is collected. Using the vacuum cleaner 1 of the present
disclosure as an up-right type cleaner by mounting the main body 20
into the cleaner frame 10 is identical to that of a conventional
up-right type cleaner.
[0032] Further, as shown in FIG. 1, dismounting the main body 20
from the cleaner frame 10 results in communicating between the dust
collector 21 and the flexible hose 49. In contrast, mounting the
main body 20 of the vacuum cleaner 1 into the cleaner frame 10 and
inclining the cleaner frame 10 results in the fluid communication
between the dust collector 21 and the flexible hose 49 being
disconnected and fluid communication between the dust collector 21
and the main brush assembly 13 by an air passage formed toward the
main brush assembly 13 is opened. Such a structure that varies an
air path by inclining of the cleaner frame 10 is well known in the
art, and thus will not be described in detail.
[0033] In the case of dismounting the main body 20 from the cleaner
frame 10 as shown in FIG. 1, a user can pull to move the main body
20 conveniently by slightly inclining it toward a side where the
traveling wheel 26a and 26b are, after connecting the extending
pipe 30 and auxiliary brush assembly 31 to the flexible hose 49 and
extending the telescopic handle 26 to agree with his/her stature as
shown in FIG. 3. When reaching a place to be cleaned, by standing
the main body 20 as shown in FIG. 3, the support member 27 comes in
contact with a floor and the main body 20 stands upright. In such
state, the user may hold the extending pipe 30 and clean the
desired place.
[0034] FIG. 4 illustrates a lower surface of a main body 20 of a
vacuum cleaner in accordance with another embodiment of the present
disclosure. As shown, two support members 127a and 127b are
installed. In such a case, a base plate 19 of a cleaner frame 10 is
provided with two recess grooves (not shown) in which the two
support members 127a and 127b can be inserted.
[0035] While the disclosure has been shown and described with
reference to certain exemplary embodiments thereof, it will be
understood by those skilled in the art that various changes in form
and details may be made therein without departing from the spirit
and scope of the disclosure as defined by the appended claims.
