The upright type vacuum cleaner has a suction port body and a cleaner body that are directly connected to each other without any extra hose or extension pipe, and improves a cleaning efficiency due to a self-weight when cleaning a carpet.
- On the other hand, the canister type vacuum cleaner has a suction port body and a cleaner body that fluidly communicate with each other through a hose and an extension pipe, and, compared to the upright type vacuum cleaner, it has an unrestricted freedom of manipulating the suction port body. Therefore, the canister type vacuum cleaner is of benefit to areas, such as narrow spaces or stairs, which impose a restriction on movement of the upright type vacuum cleaner or manipulation of the suction port.
- In recent years, a vacuum cleaner that is convertible between upright and canister modes by changing a position of a cleaner body has been developed. However, it has been determined by the present disclosure that there is a continuing need for such convertible vacuum cleaners.
- Exemplary embodiments of the present disclosure overcome the above disadvantages and other disadvantages not described above. Also, the present disclosure is not required to overcome the disadvantages described above, and an exemplary embodiment of the present disclosure may not overcome any of the problems described above.
- An aspect of the present disclosure is to provide a vacuum cleaner that is capable of cleaning a carpet by rotating a drum brush through a driving motor of a suction port body without any extra manipulation when the vacuum cleaner is operated as a canister type cleaner.
- The foregoing and/or other aspects and utilities of the present disclosure may be achieved by a vacuum cleaner including a suction port body that draws in dust from a cleaning surface therethrough, a cleaner body that separates and collects dust from air drawn in through the suction port body, an extension pipe that fluidly communicates with the suction port body, a flexible hose that is detachably connected with the cleaner body; and a manipulation handle that connects the extension pipe and the flexible hose to each other, and the suction port body has a drum brush and a driving motor that are disposed inside the suction port body, the driving motor being driven by a power supplied from the cleaner body, and the vacuum cleaner is converted into an upright type cleaner or a canister type cleaner by mounting or dismounting the cleaner body to or from the extension pipe.
- The flexible hose, the manipulation handle, and the extension pipe may have electric wires embedded therein to connect them in sequence, and the electric wires may electrically connect a power supply of the cleaner body and the driving motor to each other.
- The flexible hose may be pivotably connected with at least one of the cleaner body and the manipulation handle. The flexible hose may have a transport handle formed on a connection portion with the cleaner body to enable a user to carry the cleaner body.
- The manipulation handle may be detachably connected with the extension pipe and a cleaning accessory may be mounted on the manipulation handle if the extension pipe is detached from the manipulation handle.
- The extension pipe may have a telescopic structure so that it is compressible and expandable in its length. Accordingly, the user can property adjust the height of the manipulation handle by adjusting the length of the extension pipe when the vacuum cleaner is operated as an upright type cleaner. Also, the extension pipe can be compressed to the extent that the vacuum cleaner is placed in a small space when not in use.
- The extension pipe may be detachably connected with a connection pipe that is hinged on a rear side of the suction port body, such that the extension pipe fluidly communicates with a suction passage of the suction port body. If the vacuum cleaner is operated as an upright type cleaner, a lower portion of the cleaner body is supported on the extension pipe and an upper portion thereof is mounted on a part of the extension pipe. Accordingly, the cleaner body can be stably fixed to the extension pipe.
- The cleaner body may comprise a plurality of auxiliary wheels arranged on a rear side surface thereof opposite a cleaning surface to allow the cleaner body to move along the cleaning surface if the vacuum cleaner is operated as a canister type cleaner.
