DETAILED DESCRIPTION OF THE EXEMPLARY EMBODIMENTS

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.

Hereinafter, certain exemplary embodiments of the present disclosure will be described in detail with reference to the accompanying drawing figures.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.
