Bagless vacuum cleaner

Abstract

In a bagless vacuum cleaner, comprising a cyclonic separator having a cyclone tube ( 6 ), and a bucket ( 3 ) for containing a liquid, a diameter of the bucket ( 3 ) is at least 2 times a diameter of the cyclone tube ( 6 ). Preferably, in the bucket ( 3 ) there is a body ( 8 ) having a center in line with a center of the cyclone tube ( 6 ), a shape of the body ( 8 ) being or approximating a mushroom-shape.

1 . A bagless vacuum cleaner, comprising
 a cyclonic separator having a cyclone tube, and   a bucket for containing a liquid,   
       wherein a diameter of the bucket is at least 2 times a diameter of the cyclone tube. 
     
     
         2 . A bagless vacuum cleaner as claimed in  claim 1 , wherein the diameter of the bucket is 2.5 times the diameter of the cyclone tube. 
     
     
         3 . A bagless vacuum cleaner as claimed in  claim 1 , wherein the diameter of the bucket is at least 2.8 times a distance between the bottom of the bucket to an end of a vortex finder of the cyclonic separator. 
     
     
         4 . A bagless vacuum cleaner as claimed in  claim 3 , wherein the diameter of the bucket is at least 3 times the distance between the bottom of the bucket to the end of a vortex finder of the cyclonic separator. 
     
     
         5 . A bagless vacuum cleaner as claimed in  claim 1 , wherein in the bucket there is a body having a center in line with a center of the cyclone tube, a shape of the body being or approximating a mushroom-shape. 
     
     
         6 . A bagless vacuum cleaner as claimed in  claim 5 , wherein the body has a part having a smaller diameter than a largest diameter of the body, a height of the part corresponding to an intended level of the liquid. 
     
     
         7 . A bagless vacuum cleaner as claimed in  claim 1 , wherein the cyclone tube extends into the bucket so as to form a rim having openings for regulating an amount of liquid entering into the cyclone tube. 
     
     
         8 . A bagless vacuum cleaner, comprising
 a cyclonic separator having a cyclone tube, and   a bucket for containing a liquid,   
       wherein in the bucket there is a body having a center in line with a center of the cyclone tube, a shape of the body being or approximating a mushroom-shape. 
     
     
         9 . A bagless vacuum cleaner as claimed in  claim 8 ,
 wherein the body has a part having a smaller diameter than a largest diameter of the body, a height of the part corresponding to an intended level of the liquid.   
     
     
         10 . A bagless vacuum cleaner as claimed in  claim 8 ,
 wherein a diameter of the bucket is at least 2 times a diameter of the cyclone tube.   
     
     
         11 . A bagless vacuum cleaner as claimed in  claim 8 ,
 wherein the diameter of the bucket is 2.5 times the diameter of the cyclone tube.   
     
     
         12 . A bagless vacuum cleaner as claimed in  claim 8 ,
 wherein the diameter of the bucket is at least 2.8 times a distance between the bottom of the bucket to an end of a vortex finder of the cyclonic separator.   
     
     
         13 . A bagless vacuum cleaner as claimed in  claim 8 ,
 wherein the diameter of the bucket is at least 3 times the distance between the bottom of the bucket to the end of a vortex finder of the cyclonic separator.   
     
     
         14 . A bagless vacuum cleaner as claimed in  claim 8 ,
 wherein the cyclone tube extends into the bucket so as to form a rim having openings for regulating an amount of liquid entering into the cyclone tube.
