Brush assembly and vacuum cleaner including bursh assembly

Abstract

A brush assembly and the vacuum cleaner using such a brush assembly comprises a brush main body having an air suction opening and a turbine chamber, a turbine mounted in the turbine chamber and having an air passage, and a connecting pipe connecting a vacuum cleaner main body with the brush main body, the turbine being mounted only within a portion of the air passage. Accordingly, a brush connected with the turbine can efficiently be operated, and unpleasantness to the user caused by noise generated during cleaning can be reduced.

1 . A brush assembly comprising: 
 a brush main body having an air suction opening and a turbine chamber, the turbine chamber having an air passage;    a turbine mounted in the turbine chamber; and    a connecting pipe for connecting a vacuum cleaner main body with the brush main body, the connecting pipe further comprising a connecting pipe entrance;    wherein the turbine is mounted only within a portion of the air passage.    
   
   
       2 . The brush assembly according to  claim 1 , wherein the turbine is mounted at one side of the connecting pipe entrance opening to the turbine chamber, so as to cover only a portion of the connecting pipe entrance.  
   
   
       3 . The brush assembly according to  claim 1 , wherein the turbine is mounted in the turbine chamber and is located in the center of the connecting pipe entrance, so as to cover a central portion of the connecting pipe entrance.  
   
   
       4 . The brush assembly according to  claim 1 , wherein the turbine comprises a plurality of blades, each blade having a regularly changing thickness as measured from an inner diameter toward an outer diameter.  
   
   
       5 . The brush assembly according to  claim 4 , wherein each blade has a thickness gradually decreasing from the inner diameter toward the outer diameter of the turbine.  
   
   
       6 . The brush assembly according to  claim 1 , wherein the connecting pipe entrance further comprises a gradually decreasing diameter portion and a constant diameter portion.  
   
   
       7 . The brush assembly according to  claim 6 , wherein the connecting pipe entrance is substantially configured in the shape of a Fallopian tube.  
   
   
       8 . A vacuum cleaner comprising: 
 a cleaner main body having a dust collecting chamber;    a brush main body having an air suction opening and a turbine chamber, the turbine chamber having an air passage;    a turbine mounted in the turbine chamber; and    a connecting pipe connecting the cleaner main body with the brush main body, the connecting pipe comprising a connecting pipe entrance,    wherein the turbine is mounted only within a portion of the air passage.    
   
   
       9 . The vacuum cleaner according to  claim 8 , wherein the turbine is mounted at the turbine chamber and disposed toward one side of the entrance of the connecting pipe entrance, so as to cover only a portion of the connecting pipe entrance.  
   
   
       10 . The vacuum cleaner according to  claim 8 , wherein the turbine is mounted at the turbine chamber and is located in the center of the connecting pipe entrance, so as to cover a central portion of the connecting pipe entrance.
