BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vacuum cleaner, and more particularly, to a canister / stick combined vacuum cleaner which can be selected and used in the form of a canister or a stick.

In general, vacuum cleaners are classified into canister vacuum cleaners and stick cleaners according to their shape.

A canister vacuum cleaner is usually connected to an extension tube and a flexible hose by separating the cleaner body and the suction nozzle. Since the canister vacuum cleaner only needs to move the suction nozzle along the surface to be cleaned during cleaning, there is an advantage that the canister vacuum cleaner can be cleaned with a relatively small force. Accordingly, the canister vacuum cleaner is advantageous for cleaning a cleaning area having a large area to be cleaned. However, since the cleaner body and the suction nozzle are connected by the extension tube and the flexible hose, the length of the entire apparatus becomes long, and thus the storage and handling are difficult.

In contrast, the stick-type vacuum cleaner is integrally formed with the cleaner body which is configured to move the suction nozzle along the surface to be cleaned. Long sticks or handles are formed in the cleaner body to move and transport the cleaner body. Therefore, the stick-type vacuum cleaner can be configured to be small in length or volume, and thus there is an advantage that the storage and handling are convenient. However, the stick cleaner has a disadvantage in that a relatively large force is required because the cleaner body and the suction nozzle must be moved simultaneously along the surface to be cleaned during cleaning. Therefore, the stick vacuum cleaner is advantageous for cleaning a relatively small cleaning area in a short time.

Therefore, if the user has both a canister vacuum cleaner and a stick vacuum cleaner, the user can select one of the canister vacuum cleaner and the stick vacuum cleaner according to the cleaning conditions such as the size and the area of the cleaning area for easier and more convenient cleaning.

For example, as illustrated in FIG. 8, a suction nozzle assembly in which a suction hose 14 and a flexible hose 19 capable of cleaning a narrow area may be combined may be used as an accessory.

The operation of the canister / stick combined vacuum cleaner 1 according to the present invention configured as described above will be described in detail with reference to FIGS. 1 to 5 and 7.

First, it is assumed that the cleaner main body 10 is in the state shown in FIG. In this state, when the user wants to use the cleaner body 10 in the form of a stick, that is, the first cleaning mode in order to quickly clean a relatively narrow cleaning area, the handle member 15 has a lower end at an upper end of the pivot body 81. Is fitted on. At this time, the fixing protrusion 85 is inserted into the projection receiving hole 86, whereby the lower end of the handle member 15 is fixed to the upper end to the pivot body 81. Therefore, the handle member 15 can pivot up and down within a predetermined angle, that is, in the range of 60 to 90 degrees with respect to the cleaner body 10 by the pivot body 81.

At this time, since the cleaner body 10 is in the state shown in FIG. 1, the blocking plate 78 of the blocking member 77 is positioned at the first position by the elastic spring 79 as shown in FIG. 4A. That is, the blocking plate 78 seals the first pipe portion 72 of the pipe member 71 to block the flow path between the suction nozzle 16 and the dust collector 41, and opens the second pipe portion 73. The flow path between the suction unit 20 and the dust collector 41 is in communication.

In this state, while applying power to the cleaner and moving the cleaner body 10 along the surface to be cleaned by the handle member 15, the air containing the dirt on the surface to be cleaned is removed from the suction unit 20. It is introduced into the cyclone body 43 through the air suction port 22, the second pipe part 73 of the pipe member 71, and the air inlet 44. The introduced air forms a swirling airflow through the guide member 46 and the discharge pipe 49, and the relatively large dirt contained in the air is discharged through the dust discharge opening 50 by centrifugal force to discharge the dust guide 51. Through the waste container 59 is collected. The large dirt-free air passes through the discharge pipe 49 and exits through the air discharge port 45 and the filter 65 to the motor chamber 23. In this case, dirt larger than the micropores of the filter 65 is filtered without being introduced into the motor chamber 23 in which the suction motor 21 is installed. The air introduced into the motor chamber 23 is discharged to the outside through the air discharge passage 24.

After the cleaning is completed, when the dust or dirt collected in the waste container 59 is to be emptied, when the detachable lever 63 is rotated at a predetermined angle, the cam surface of the cam 64 becomes the waste container 59. It is spaced apart from the front surface, and thus the rear end surface of the waste container 59 is released from the press-fixed state with the dust guide 51. Therefore, the waste container 59 can be freely removed from the cleaner body 10 by the container handle 69. At this time, as shown in Figure 3a, since the dust-proof cover 61 is extended in parallel with the bottom surface of the waste container 59 by the elastic force of the elastic spring 62, dust or dirt in the waste container 59 Is not poured out from the waste container (59).

Then, as shown in Figure 7, if the user wants to use the cleaner body 10 in the canister form, that is, the second cleaning mode to clean a relatively large cleaning area, the handle member 15 has a lower end pivot body ( 81 is removed from the upper end of the). At this time, the fixing protrusion 85 is pressed by the push button 87 to release the locking with the projection receiving hole 86.

Then, as shown in FIG. 4B, the connection portion 19a of the flexible hose 19 of the suction nozzle / handle assembly is inserted into and fixed to the first tube portion 72 of the tube member 71. At this time, the blocking plate 78 of the blocking member 77 is pushed against the elastic spring 79 by the connecting portion 19a and moved to the second position. That is, the blocking plate 78 seals the second pipe portion 73 of the pipe member 71 to block the flow path between the suction unit 20 and the dust collecting unit 40, and opens the first pipe portion 72. The flow path between the suction nozzle 16 and the dust collecting unit 40 is communicated.

In this state, when power is supplied to the cleaner 1 and the suction nozzle 16 is moved along the surface to be cleaned, the air containing the dirt on the surface to be cleaned is introduced into the air intake port of the suction nozzle 16 (not shown). Inside the cyclone body 43 through the variable extension tube 17, the operation handle 18, the flexible hose 19, the first tube portion 72 of the tube member 71, and the air inlet 44. Flows into. The air introduced into the cyclone body 43 is discharged to the outside after dust is removed by the dust collecting unit 40 and the filter 65 as described above with respect to the first cleaning mode.

As described above, the canister / stick combined vacuum cleaner according to the embodiment of the present invention can be used by selecting one of the canister type and the stick type according to the cleaning conditions such as the size and area of the cleaning area. As in the prior art, the user does not need to have both a canister vacuum cleaner and a stick vacuum cleaner to cope with various cleaning conditions. Therefore, the economic burden on the user may be reduced, and the device utilization efficiency may be improved.

In addition, the canister / stick combined vacuum cleaner according to the embodiment of the present invention can be easily converted into a canister type or stick type by simply attaching a handle member or detaching the handle member and mounting a suction nozzle and / or handle assembly. As it can be, it is easy to use and convenient.
