Vacuum cleaner

Abstract

A vacuum cleaner comprises a cleaner body having a suction force source and a dirt separator for separating dirt particles from air drawn in by the suction force, a dirt receptacle located under the dirt separator and removably mounted in the cleaner body, and a handle unit which a user holds to carry the vacuum cleaner. The handle unit prevents disconnection of the dirt separator and the dirt receptacle while in a carrying position.

1 . A vacuum cleaner comprising: 
 a cleaner body having a suction force source and a dirt separator for separating dirt particles from air drawn in by the suction force;    a dirt receptacle located under the dirt separator and removably mounted in the cleaner body; and    a handle unit which a user holds to carry the vacuum cleaner, for preventing the dirt separator and the dirt receptacle from being disconnected from each other.    
   
   
       2 . The vacuum cleaner as claimed in  claim 1 , wherein the handle unit comprises: 
 a handle disposed on the cleaner body;    a lever disposed on the dirt separator and contacting one side of the handle;    a lever connector disposed on the cleaner body, the lever being locked into and unlocked from the lever; and    a second elastic member pressing the lever in a direction such that the lever is unlocked from the lever connector, and    wherein, as a user holds handle in an upright position, the lever is locked into the lever connector, thereby preventing the dirt separator and the dirt receptacle from being disconnected from each other.    
   
   
       3 . A vacuum cleaner comprising: 
 a cleaner body;    a dirt separator rotatably disposed in the cleaner body;    a dirt receptacle removably mounted in the cleaner body, and    a handle unit which a user holds to carry the vacuum cleaner, for preventing the dirt separator and the dirt receptacle from being disconnected from each other.    
   
   
       4 . The vacuum cleaner as claimed in  claim 3 , further comprising a locking unit for locking or unlocking the dirt separator and the dirt receptacle.  
   
   
       5 . The vacuum cleaner as claimed in  claim 4 , further comprising a cover rotatably disposed on the cleaner body, the dirt separator being connected with the cover.  
   
   
       6 . The vacuum cleaner as claimed in  claim 5 , wherein the locking unit comprises: 
 a button disposed on a handle of the dirt receptacle and having a hook formed thereon;    a securing part disposed on the dirt separator, the hook of the button being hooked in or released from the securing part; and    a first elastic member pressing the button in a locking direction.    
   
   
       7 . The vacuum cleaner as claimed in  claim 6 , wherein the securing part comprises: 
 a support protrusion protruding from the dirt separator; and    a hook connecting portion formed at a lower portion of the support protrusion.    
   
   
       8 . The vacuum cleaner as claimed in  claim 5 , wherein the handle unit comprises: 
 a handle disposed on the cleaner body;    a lever disposed on the dirt separator and contacting one side of the handle;    a lever connector disposed on the cleaner body, the lever being locked into or unlocked from the lever connector; and    a second elastic member pressing the lever in a direction such that the lever is unlocked from the lever connector,    wherein as a user holds the handle in an upright position, the lever is locked into the lever connector, thereby preventing the dirt separator and the dirt receptacle from being disconnected from each other.    
   
   
       9 . The vacuum cleaner as claimed in  claim 8 , wherein the handle comprises: 
 a holding part which a user holds; and    a contact portion formed at a lower portion of the holding part.    
   
   
       10 . The vacuum cleaner as claimed in  claim 9 , wherein the contact portion is guided along a guide recess formed in the dirt separator to press the lever.
