Suction hose supporting structure for upright type vacuum cleaner capable of being converted to canister type

Abstract

Disclosed herein is a suction hose supporting structure of an upright type vacuum cleaner capable of being converted to a canister type. The vacuum cleaner comprises a main body having a suction port and a discharge port, a suction unit having a dust collecting port and a discharge opening, an extension pipe and a handle detachably installed to the main body, a suction hose connected at one end with the suction port and selectively connected at the other end with the discharge opening or the handle, a bending prevention member installed at one side of the suction port to support the suction hose in a round state, and a fixing ring installed to one side of the suction hose and having a hook. When the vacuum cleaner is used as the upright type, the suction hose is prevented from being bent, thereby minimizing resistance in a flow passage.

1 . A suction hose supporting structure of an upright type vacuum cleaner capable of being converted to a canister type, comprising: 
 a main body having a suction port and a discharge port formed thereon, and including a suction device inside the suction port;    a suction unit having a dust collecting port and a discharge opening, on which the main body is detachably installed;    an extension pipe and a handle detachably installed to the main body, and having a hollow inner space to define a flow passage along which air containing foreign substances is induced;    a suction hose connected at one end with the suction port, and selectively connected at the other end with the discharge opening or the handle; and    a bending prevention member installed at one side of the suction port to support the suction hose in a round state.    
   
   
       2 . The suction hose supporting structure according to  claim 1 , further comprising: a fixing ring installed at one side of the suction hose and having a hook positioned on a circumferential surface thereof so as to be hung on one side of the main body.  
   
   
       3 . The suction hose supporting structure according to  claim 1 , wherein the main body has a fastening boss formed on an upper end corresponding to the bending prevention member, and an insertion groove formed at the side corresponding to the fixing ring.  
   
   
       4 . The suction hose supporting structure according to  claim 1 , wherein the bending prevention member comprises a round panel on which the suction hose is seated, and a coupling hole part formed at a lower end of the round panel and to which the fastening boss is coupled.  
   
   
       5 . The suction hose supporting structure according to  claim 3 , wherein the main body has a rib formed around a portion separated a predetermined distance from the fastening boss so as to be brought into close contact with an inner wall of the coupling hole part.  
   
   
       6 . The suction hose supporting structure according to  claim 5 , wherein the rib has a seating groove formed therearound, and into which lower ends of the round panel and the coupling hole part are inserted.  
   
   
       7 . The suction hose supporting structure according to  claim 4 , wherein the main body has a rib formed around a portion separated a predetermined distance from the fastening boss so as to be brought into close contact with an inner wall of the coupling hole part.  
   
   
       8 . The suction hose supporting structure according to  claim 7 , wherein the rib has a seating groove formed therearound, and into which lower ends of the round panel and the coupling hole part are inserted.
