<p>* P521570GB * 2439277 Vacuum Cleaner This invention relates to a vacuum
cleaner, and in particular to a vacuum cleaner having a main body mounted in a frame, thereby being usable as an upright vacuum cleaner as well as being usable as a canister vacuum cleaner following detaching the main body from the frame.</p>
<p>It is well known that the main body of an upright vacuum cleaner can be detached from its frame so as to carry and use only the main body for cleaning.</p>
<p>A known conventional vacuum cleaner, which is used for cleaning a limited space such as stairs or a curtain, has a large nozzle unit coupled to the lower end of a cleaner frame.</p>
<p>An extension pipe connected to a main body of the vacuum cleaner can be used to operate an auxiliary nozzle unit using one hand, while the heavy main body can be carried using the other hand. It is, therefore, inconvenient to clean limited spaces whilst carrying the heavy main body, and it is hard to clean a floor when the main body is standing on the floor, as the height of the main body is low.</p>
<p>An aim of the invention is to provide a vacuum cleaner that it is convenient for a user to carry, and whose main body can be used for cleaning when it is detached from its frame.</p>
<p>The present invention provides a vacuum cleaner comprising: a main body having a dust collector and a vacuum motor; a cleaner frame in which the main body is detachably mounted; a main nozzle unit connected to a lower end of the cleaner frame; and a flexible hose and an auxiliary nozzle unit connected to the main body, wherein the main body is provided with at least one wheel and with a support member, and wherein, when the main body is mounted in the cleaner frame, an upright cleaning operation can be performed by sucking external air into the main nozzle unit, and, when the main body is dismounted from the cleaner frame, the main body can be wheeled and supported upright by the support member, and a canister cleaning operation can be performed by sucking external air through the auxiliary nozzle unit.</p>
<p>Preferably, the main body further comprises an adjustable telescopic handle.</p>
<p>in a preferred embodiment, the main body is provided with two wheels that are installed at a lower end thereof.</p>
<p>Advantageously, the cleaner frame further comprises a base plate for fixing to the lower end of the main body and a locking member for locking a side surface of the main body.</p>
<p>Preferably, the base plate is provided with a pair of wheel insert grooves in which the wheels are inserted, and with a recess groove in which the support member is inserted.</p>
<p>With this vacuum cleaner, as a user does not need to carry the heavy main body of the vacuum cleaner, but can pull it along on the wheels, whereby the main body can easily be moved for cleaning using the auxiliary nozzle unit.</p>
<p>Further, as the length of the handle of the main body is adjustable to complement a user's stature, there is no need for the user to bend forward during cleaning, so that the cleaner is convenient to use.</p>
<p>The invention also provides a vacuum cleaner comprising: a main body having a lower end and an auxiliary nozzle unit, the lower end including a pair of wheels and at least one support member; and a cleaner frame having a base plate and a main nozzle unit, the base plate including a pair of wheel insert grooves and a recess groove, wherein, for an upright cleaning operation, external air is drawn into the main nozzle unit and the main body is mounted in the cleaner frame on the base plate so that the wheels are received by the wheel insert grooves and the support member is received by the recess groove, and wherein, for a canister cleaning operation, external air is drawn into the auxiliary nozzle unit, and the main body is dismounted from the cleaner frame so that the main body is movable using the wheels.</p>
<p>The invention will now be described in greater detail, by way of example, with reference to the drawings, in which: Figure. 1 is a perspective view showing a first form of vacuum cleaner constructed in accordance with the invention; Figure. 2 is an underneath view of the main body of the vacuum cleaner of Figure. 1; Figure. 3 is a perspective view showing one way of using the vacuum cleaner of Figure.</p>
<p>1; and Figure. 4 is an underneath view of the main body of a second form of vacuum cleaner constructed in accordance with the invention.</p>
<p>Throughout the drawings, the same reference numerals will be used to refer to the same 1 5 elements, features, arid structures.</p>
<p>In the following description, the same reference numerals are used to identify the same or similar elements in the different figures. The matters set forth in the description below, such as the detailed construction and method of operation, are only provided to assist in a comprehensive understanding of the invention, and should not be considered as limiting. The present invention can be carried out without using some or all of those defined elements. Well-known functions or constructions are not described in detail to avoid obscuring the invention in unnecessary detail.</p>
<p>Referring to the drawings, Figure 1 shows a vacuum cleaner having a main body 20, a cleaner frame 10, a main nozzle unit 13, a flexible hose 49, an extension pipe 30, and an auxiliary nozzle unit 31. The main body 20 can be detachably mounted to the cleaner frame 10.</p>
<p>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, 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, the dust canister being detachably mounted to the main body 20.</p>
<p>The motor chamber 25 is provided at the lower end of the dust canister 23, and the suction motor transfers suction power through the dust collector 21 to the main nozzle unit 13 or to the auxiliary nozzle unit 31.</p>
<p>The telescopic handle 28 is installed on top of a frame 42 of the main body 20, and its length is adjustable in an up/down direction so that a user can adjust the height of the telescopic handle to complement his or her stature (see Figure 3). The wheels 26a and 26b help moving the main body 20, the wheels being installed at opposite sides of the lower end of the frame 42 of the main body 20 as shown in Figures 1 and 2. The support member 27 projects downwards with a slight slope from a lower end of the motor chamber 25, so that the main body 20 can stand upright, and does not fall down when the main body 20 is stood upright on a floor. Thus, a user may move the main body 20 by slightly inclining it towards the wheels 26a and 26b after extending the telescopic handle 28 to complement his/her stature. In a place to be cleaned, the user may clean by holding the extension pipe 30 after standing the main body 20 upright on the floor, with the support member 27 in contact with the floor so as to prevent the main body from moving.</p>
<p>The cleaner frame 10 (see Figure 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. Main wheels 18 are provided at the lower end of the two columns 8 and 9. The hand grip 15 is integrally configured with the upper portions of the two columns 8 and 9, and the two columns are separated from each other by a predetermined distance, thereby defining the mounting space 11 therebetween. The base plate 19 is configured to support the lower surface of the main body 20, and is provided integrally in a lower portion of the mounting space 11, that is to say between the bases of the two columns 8 and 9.</p>
<p>The base plate 19 is formed with a recess groove 17 into which the support member 27 is inserted, and with two wheel inserting grooves 16a and 16b into which the wheels 26a and 26b are inserted. The main body 20 includes an inlet 43 (see Figure 1) of an air passage, which delivers external air flowing through the main nozzle unit 13 to the main body, the inlet being in tight contact with an air inlet 45 (see Figure 2) formed at a lower surface of the main body. A respective locking member 47 is installed at an inside surface of each of the two columns 8 and 9. Thus, once the main body 20 of the vacuum cleaner I is mounted into the mounting space ii, the main body is not easily separated from the cleaner frame 10 by the locking members 47.</p>
<p>The main nozzle unit 13 is connected to the base plate 19 of the cleaner frame 10.</p>
<p>When the main nozzle unit 13 comes in contact with a surface to be cleaned, cleaning can be carried out by external air which flows through the main nozzle unit into the main body 20.</p>
<p>Referring to Figure 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 nozzle unit 31 by the extension pipe 30. Thus, external air can flow into the auxiliary nozzle unit 31, through the extension hose 30, and through 1 5 the flexible hose 49 into the dust collector 21.</p>
<p>A cleaning operation using the vacuum cleaner I will now be described with reference to Figures ito 3.</p>
<p>In Figure 1, the vacuum cleaner 1 can be used as an upright cleaner by inserting the main body 20 into the mounting space 11, so that the lower surface of the main body 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 rearwards, the main nozzle unit 13 and the air passage of the main body 20 communicate with each other, and external air flows through the main nozzle unit 13 into the main body so that dust is collected.</p>
<p>Using the vacuum cleaner I as an upright cleaner by mounting the main body 20 into the cleaner frame 10 is identical to that of a conventional upright cleaner.</p>
<p>Further, as shown in Figure 1, dismounting the main body 20 from the cleaner frame 10 results in communication 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 results in 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 nozzle unit 13 being opened. Such a structuTe that varies its air path by inclining of the cleaner frame 10 is well known in the art, and thus will not be described in detail.</p>
<p>When the main body 20 is disconnected from the cleaner frame 10, as shown in Figure I, a user can easily move the main body 20 by slightly inclining it towards the wheels 26a and 26b, after connecting the extension pipe 30 and the auxiliary nozzle unit 31 to the flexible hose 49 and extending the telescopic handle 28 to complement his/her stature, as shown in Figure 3. When reaching a place to be cleaned, the main body 20 can be stood upright as shown in Figure 3, with the support member 27 in contact with the floor. In such a position, the user can hold the extension pipe 30 and carry out cleaning of that place.</p>
<p>Figure. 4 illustrales the lower surface of a main body 20 of a second form of vacuum cleaner. As shown, two support members 1 27a and 1 27b are provided. In such a case, the base plate 19 of the cleaner frame 10 is provided with two recess grooves (not shown) into which the two support members 127a and 127b can be inserted.</p>
<p>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 scope of the invention as defined by the claims.</p>
