Canister-type vacuum cleaner

Abstract

A canister-type vacuum cleaner has a cleaner body having a driving portion for generating a suction force and a dust chamber for collecting contaminants that are drawn in by the suction force of the driving unit; a suction extension pipe connected to the cleaner body; a suction brush disposed at an end of the suction extension pipe to draw in the contaminants of a cleaning surface with the suction force that is transmitted via the suction extension pipe; and an electrolytic liquid supply device disposed at the suction extension pipe, for spraying an electrolytic liquid to the cleaning surface through a lower side of the suction brush.

What is claimed is:  
     
         1 . A canister-type vacuum cleaner, comprising: 
 a cleaner body having a driving portion for generating a suction force and a dust chamber for collecting contaminants that are drawn in by the suction force of the driving portion;    a suction extension pipe connected to the cleaner body;    a suction brush disposed at an end of the suction extension pipe to draw in the contaminants of a cleaning surface with the suction force that is exerted via the suction extension pipe; and    an electrolytic liquid supply device disposed at the suction extension pipe, for spraying an electrolytic liquid to the cleaning surface through a lower side of the suction brush.    
     
     
         2 . The canister-type vacuum cleaner of  claim 1 , wherein the electrolytic liquid supply device comprises: 
 an electrolytic liquid generating unit disposed at the suction extension pipe, for generating the electrolytic liquid from a raw water supply; and    a spray unit for spraying the electrolytic liquid, through an air suction port of the suction brush.    
     
     
         3 . The canister-type vacuum cleaner of  claim 2 , wherein the spray unit comprises: 
 a feeding path connecting the electrolytic liquid generating unit and the air suction port of the suction brush;    a spray pump disposed on the feeding path; and    a spray nozzle formed at an end of the feeding path, for spraying the electrolytic liquid through the air suction port.
