Vacuum cleaner

Abstract

A vacuum cleaner which is hygienically usable. The vacuum cleaner includes a main body forming the external appearance thereof, a blowing fan for generating a suction force to allow external air including foreign substances to be sucked into the main body, and a nano particle generator for generating nano particles and dispersing the generated nano particles into the air sucked thereinto. Since the foreign substances accumulated in a main body of the vacuum cleaner or the air discharged to the outside are sterilized by means of the sterilizing power of the nano particles generated from the nano particle generator, the vacuum cleaner is hygienically usable.

1 . A vacuum cleaner comprising: 
 a main body forming the external appearance thereof;    a blowing fan to generate a suction force to allow external air including foreign substances to be sucked into the main body; and    a nano particle generator to generate nano particles and to disperse the generated nano particles into the air sucked thereinto.    
   
   
       2 . The vacuum cleaner as set forth in  claim 1 , further comprising a dust collector to filter out the foreign substances contained in the air flowing by the blowing fan.  
   
   
       3 . The vacuum cleaner as set forth in  claim 2 , wherein the dust collector includes a foreign substance filter installed in a channel of the air blown by the blowing fan to filter out the foreign substances from the air passing therethrough.  
   
   
       4 . The vacuum cleaner as set forth in  claim 3 , wherein: 
 the nano particle generator is positioned in the main body such that the nano particle generator is communicated with an outlet and an inlet of the foreign substance filter; and    a subsidiary blowing fan is provided in the main body to cause the air to flow from the outlet of the foreign substance filter to the inlet of the foreign substance filter through the nano particle generator.    
   
   
       5 . The vacuum cleaner as set forth in  claim 3 , further comprising: 
 a brush head contacting a surface of a place to be cleaned;    an extension pipe connected with the brush head; and    a connection hose comprising an elastically deformable material to connect the extension pipe and the main body,    wherein the brush head, the extension pipe and the connection hose are connected with the main body, and the nano particle generator is installed in the extension pipe for dispersing the nano particle into air passing through the extension pipe.    
   
   
       6 . The vacuum cleaner as set forth in  claim 5 , further comprising a damper is provided at an end of the connection hose to close one end of the connection hose close to the main body when it is necessary to sterilize an inside of the main body when the inside of the main body is not cleaned.  
   
   
       7 . The vacuum cleaner as set forth in  claim 2 , wherein the dust collector comprises: 
 a cyclone chamber comprising an upper portion having a cylindrical shape and a lower portion having a conical shape;    a suction pipe connected with the cyclone chamber in a tangential direction; and    a discharge pipe positioned in a central part of the cyclone chamber in an axial direction.    
   
   
       8 . The vacuum cleaner as set forth in  claim 7 , wherein the nano particle generator is positioned in the discharge pipe to disperse the nano particles into air discharged to an outside through the discharge pipe.  
   
   
       9 . The vacuum cleaner as set forth in  claim 7 , wherein the nano particle generator is positioned in the suction pipe to disperse the nano particles into air supplied to the cyclone chamber through the suction pipe.  
   
   
       10 . The vacuum cleaner as set forth in  claim 1 , wherein the nano particle generator comprises: 
 a material-receiving portion having a concave shape to receive a material used to generate the nano particles; and    a heater positioned in the material-receiving portion, such that the heater contacts the material received by the material-receiving portion, to generate heat to heat the material.    
   
   
       11 . A vacuum cleaner comprising: 
 a main body forming the external appearance thereof;    a blowing fan to generate a suction force to allow external air including foreign substances to be sucked into the main body;    a dust collector to filter out the foreign substances contained in the air flowing by the blowing fan; and    a nano particle generator positioned at an inlet of the dust collector to generate nano particles and to disperse the generated nano particles into the air introduced into the dust collector.    
   
   
       12 . A vacuum cleaner comprising: 
 a main body forming the external appearance thereof;    a blowing fan to generate a suction force to allow external air including foreign substances to be sucked into the main body;    a dust collector to filter out the foreign substances included in the air flowing by the blowing fan; and    a nano particle generator positioned at an outlet of the dust collector to generate nano particles and to disperse the generated nano particles into the air discharged from the dust collector.    
   
   
       13 . The vacuum cleaner as set forth in  claim 8 , wherein the nano particle generator is positioned in a central part of the discharge pipe in an axial direction, and disperses nano particles into air passing through the discharge pipe to sterilize the air.
