Vacuum cleaner having detachable dust separating unit

Abstract

A vacuum cleaner having a detachable dust separating unit is disclosed. The vacuum cleaner includes a cleaner body having a first opening to open a portion of a first surface thereof and a second opening to open a portion of a second surface thereof, a dust separating unit to separate a dust from an air, and a seating part formed in the cleaner body to detachably mount the dust separating unit on the cleaner body. The dust separating unit forms a portion of an outward appearance of the cleaner body while closing up the first and the second openings of the cleaner body when the dust separating unit is mounted on the seating part.

1 . A vacuum cleaner comprising:
 a cleaner body having a first opening to open a portion of a first surface thereof and a second opening to open a portion of a second surface thereof;   a dust separating unit to separate a dust from an air; and   a seating part formed in the cleaner body to detachably mount the dust separating unit on the cleaner body,   wherein the dust separating unit forms a portion of an outward appearance of the cleaner body while closing up the first and the second openings of the cleaner body when the dust separating unit is mounted on the seating part.   
   
   
       2 . The cleaner as claimed in  claim 1 , wherein the seating part comprises a recess with an accommodating space fluidly communicated with the first and the second openings of the cleaner body and formed in a shape corresponding to the dust separating unit. 
   
   
       3 . The cleaner as claimed in  claim 2 , wherein the accommodating space is inclined to ascend toward at least the second opening with respect to a horizontal plane. 
   
   
       4 . The cleaner as claimed in  claim 1 , wherein the dust separating unit is configured, so that when the dust separating unit is mounted on the seating part, a portion thereof is projected to the outside through the first and the second openings of the cleaner body. 
   
   
       5 . The cleaner as claimed in  claim 1 ,
 wherein the dust separating unit comprises a first cyclone unit to draw in an air and to first centrifugally separate a dust from the air, and a second cyclone unit to second centrifugally separate a dust from the air discharged from the first cyclone unit, and   wherein the first cyclone unit comprises a portion that is projected to the outside through the second opening of the cleaner body and the second cyclone unit comprises a portion that is projected to the outside through the first opening.   
   
   
       6 . The cleaner as claimed in  claim 5 , wherein the first and the second cyclone units are detachably coupled to or with each other. 
   
   
       7 . The cleaner as claimed in  claim 5 , wherein the first cyclone unit draws in the air at a lower part thereof and discharges the air at an upper part thereof. 
   
   
       8 . The cleaner as claimed in  claim 7 , wherein the first cyclone unit comprises:
 a first cyclone chamber having an air inlet at the lower part thereof;   a center pipe disposed in a center of the first cyclone chamber, to guide a rotation of the air drawn in through the air inlet;   a first dust collecting chamber disposed around the first cyclone chamber, to store the dust centrifugally separated from the first cyclone chamber; and   a second dust collecting chamber disposed at one side of the first dust collecting chamber, to store the dust centrifugally separated by the second cyclone unit.   
   
   
       9 . The cleaner as claimed in  claim 8 , wherein the first dust collecting chamber is formed in a shape having a semicircular cross section, and the second dust collecting chamber is formed in a shape having a rectangular cross section. 
   
   
       10 . The cleaner as claimed in  claim 8 , wherein the first dust collecting chamber is configured so that at least a portion thereof closes up the second opening of the cleaner body when the dust separating unit is mounted on the seating part. 
   
   
       11 . The cleaner as claimed in  claim 8 , wherein the first cyclone unit further comprises a handle formed on the first dust collecting chamber. 
   
   
       12 . The cleaner as claimed in  claim 11 , wherein the handle is configured so that at least a portion thereof is projected to the outside through the second opening of the cleaner body. 
   
   
       13 . The cleaner as claimed in  claim 5 , wherein the second cyclone unit comprises at least two cyclones horizontally disposed parallel to each other above the first cyclone unit. 
   
   
       14 . The cleaner as claimed in  claim 13 , wherein each of the at least two cyclones is configured so that at least a portion thereof is projected to the outside through the first opening of the cleaner body. 
   
   
       15 . The cleaner as claimed in  claim 13 , wherein the second cyclone unit further comprises a first cover to open and close up an upper part of the first cyclone unit. 
   
   
       16 . The cleaner as claimed in  claim 15 , wherein the first cover is configured to open and close up a first dust collecting chamber and a second dust collecting chamber of the first cyclone unit at the same time. 
   
   
       17 . The cleaner as claimed in  claim 13 , wherein the second cyclone unit further comprises a grill member to filter a dust from the air discharged from the first cyclone unit. 
   
   
       18 . The cleaner as claimed in  claim 17 , wherein the grill member is configured, so that at least a portion thereof is projected into the first cyclone chamber of the first cyclone unit and maintained in a spaced-apart relation to a center pipe of the first cyclone unit. 
   
   
       19 . The cleaner as claimed in  claim 13 , wherein the second cyclone unit further comprises a second cover to open and close up the first opening of the cleaner body. 
   
   
       20 . The cleaner as claimed in  claim 19 , wherein the second cover is configured to close up the first opening when the dust separating unit is mounted on the seating part.
