Vacuum cleaner

Abstract

A vacuum cleaner is provided that comprises a dust collection unit mounted to a mounting portion of a cleaner body. The dust collection unit separates dust from outside air being drawn in. The dust collection unit has a handle and a locking unit for detachably fixing the dust collection unit to the cleaner body. Here, the locking unit comprises a locking member moving between a connecting position and a releasing position, the connecting position for being engaged with a connection recess formed on the cleaner body and the releasing position for being released from the connection recess; and a button member formed on an outer surface of the dust collection unit for pressing operation.

1 . A vacuum cleaner comprising: 
 a cleaner body having a mounting portion;    a dust collection unit for separating dust from outside air, the dust collection unit being mounted to the mounting portion, the dust collection unit having a handle and a locking unit for detachably fixing the dust collection unit mounted in the mounting portion with respect to the cleaner body, wherein the locking unit comprises: 
 a locking member for movement between a connecting position and a connecting position, the connecting position for being engaged with a connection recess formed on the cleaner body and the releasing position for being released from the connection recess; and  
 a button member formed on an outer surface of the dust collection unit for pressing operation, and  
   wherein when a user grabs the handle of the dust collection unit, the button member is pressed from an initial position so that the locking member is moved from the connecting position to the releasing position, thereby releasing the dust collection unit from the cleaner body.    
   
   
       2 . The vacuum cleaner of  claim 1 , wherein the locking unit further comprises a releasing member moved in association with the locking member, and a gear member operating the releasing member and the button member in association with each other.  
   
   
       3 . The vacuum cleaner of  claim 2 , wherein the gear member converts a rotational motion of the button member to a linear motion and transmits the linear motion to the releasing member.  
   
   
       4 . The vacuum cleaner of  claim 3 , wherein the gear member, the locking member, and the releasing member are integrally formed.  
   
   
       5 . The vacuum cleaner of  claim 3 , wherein the button member comprises a partition protruded from one side thereof to press the gear member during the rotational movement of the button member.  
   
   
       6 . The vacuum cleaner of  claim 1 , further comprising a cover part mounted to an upper part of the dust collection part to cover the upper part of the dust collection part, wherein the button member and the handle are disposed on the cover part to face each other, and the button member is hinged on the cover part.  
   
   
       7 . The vacuum cleaner of  claim 1 , wherein the locking unit further comprises a spring for restoring the button member to the initial position when the user releases the handle.  
   
   
       8 . The vacuum cleaner of  claim 1 , wherein the dust collection unit comprises a dust collection part for drawing in the outside air, centrifugally separating dust from the outside air, and collecting the separated dust, and a cover part mounted to an upper part thereof to cover the dust collection unit, the cover part comprises the button member on a top side and the releasing member therein, and the locking member is integrally formed with either side of the releasing member.  
   
   
       9 . The vacuum cleaner of  claim 8 , further comprising a grab space for inserting user's fingers formed inside the cover part so that when the user inserts fingers in the grab space, the button member is pressed, thereby releasing connection between the dust collection unit and the cleaner body.  
   
   
       10 . A vacuum cleaner comprising 
 a dust collection unit having a handle;    a cleaner body; and    a vacuum source mounted to the cleaner body and generating a suction force,    wherein when the handle is grabbed, the dust collection unit is separated from the cleaner body and when the handle is released, the dust collection unit is locked to the cleaner body.    
   
   
       11 . The vacuum cleaner of  claim 10 , wherein the dust collection unit comprises a locking unit, and the locking unit comprises a button member that rotates and at least one locking member that is linearly moved by rotation of the button member.  
   
   
       12 . The vacuum cleaner of  claim 11 , wherein the locking unit further comprises a gear member converting rotational motion of the button member to linear motion.
