Vacuum cleaner used as both upright type cleaner and canister type cleaner

Abstract

A vacuum cleaner convertible between upright and canister modes is provided. The vacuum cleaner includes 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, wherein 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, wherein 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.

1 . A vacuum cleaner comprising:
 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,   wherein 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,   wherein 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, and   wherein the power is supplied from the cleaner body to the driving motor when the vacuum cleaner is converted into the upright type cleaner or the canister type cleaner.   
   
   
       2 . The vacuum cleaner as claimed in  claim 1 , wherein the flexible hose, the manipulation handle, and the extension pipe have electric wires embedded therein to connect them in sequence, and the electric wires electrically connect a power supply of the cleaner body and the driving motor to each other. 
   
   
       3 . The vacuum cleaner as claimed in  claim 2 , wherein the flexible hose is pivotably connected with at least one of the cleaner body and the manipulation handle. 
   
   
       4 . The vacuum cleaner as claimed in  claim 3 , wherein the flexible hose has a transport handle formed on a connection portion with the cleaner body to enable a user to carry the cleaner body. 
   
   
       5 . The vacuum cleaner as claimed in  claim 1 , wherein the manipulation handle is detachably connected with the extension pipe and a cleaning accessory is mounted on the manipulation handle if the extension pipe is detached from the manipulation handle. 
   
   
       6 . The vacuum cleaner as claimed in  claim 1 , wherein the extension pipe has a telescopic structure so that it is compressible and expandable in its length. 
   
   
       7 . The vacuum cleaner as claimed in  claim 1 , wherein the extension pipe is 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. 
   
   
       8 . The vacuum cleaner as claimed in  claim 7 , wherein, 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. 
   
   
       9 . The vacuum cleaner as claimed in  claim 1 , wherein the cleaner body comprises a plurality of auxiliary wheels arranged on a rear side surface thereof to allow the cleaner body to move along the cleaning surface if the vacuum cleaner is operated as a canister type cleaner.
