Vacuum cleaner

Abstract

A vacuum cleaner has an air path for drawn air, one or more portions of which have their surfaces nano-coated with an antibiosis and sterilization material. In an embodiment, a vacuum cleaner has a suction brush with an air inlet, a dust collecting apparatus in fluid communication with the suction brush, and a body having mounting locations for a dust collecting apparatus and a motor assembly to generate suction force. One or more portions of the air path surface of the dust collecting apparatus that contacts the air is nano-coated with an antibiosis and sterilization material.

1 . A vacuum cleaner comprising 
 a suction brush having an air inlet;    a dust collecting apparatus in fluid communication with the suction brush and separating and collecting contaminants from intake air;    a motor assembly generating a suction force of air; and    a body comprising a dust collecting apparatus mounting location and a motor assembly mounting location,    wherein at least a surface of an air path of the dust collecting apparatus contacting the intake air drawn via the air inlet is nano-coated with an antibiosis and sterilization material.    
   
   
       2 . The vacuum cleaner of  claim 1 , wherein a surface of the dust collecting apparatus proximate to a filter mounting location is nano-coated with the antibiosis and sterilization material.  
   
   
       3 . The vacuum cleaner of  claim 1 , wherein a surface of the dust collecting apparatus where collected contaminants are accumulated is nano-coated with the antibiosis and sterilization material.  
   
   
       4 . The vacuum cleaner of  claim 1 , wherein when a dust bag is applied to the dust collecting apparatus, an inner surface of the dust collecting apparatus mounting location is nano-coated with the antibiosis and sterilization material.  
   
   
       5 . The vacuum cleaner of  claim 1 , wherein the antibiosis and sterilization material comprises silver.  
   
   
       6 . The vacuum cleaner of  claim 1 , wherein the antibiosis and sterilization material is nano-coated by a chemical vapor deposition (CVD) method.  
   
   
       7 . A vacuum cleaner comprising: 
 a suction brush having an air inlet;    a dust collecting apparatus in fluid communication with the suction brush to separate and collect contaminants from intake air;    a motor assembly generating a suction force; and    a body comprising a dust collecting apparatus mounting location and a motor assembly mounting location,    wherein inner surfaces of the air inlet and air inlet path of the suction brush contacting the air, an inner surface of a path connecting the suction brush and the dust collecting apparatus, and an air path surface of the dust collecting apparatus are nano-coated with an antibiosis and sterilization material.    
   
   
       8 . The vacuum cleaner of  claim 7 , wherein a surface of the motor assembly mounting location in contact with air drawn from the dust collecting apparatus mounting location is nano-coated with the antibiosis and sterilization material.  
   
   
       9 . The vacuum cleaner of  claim 7 , wherein the antibiosis and sterilization material comprises silver.  
   
   
       10 . The vacuum cleaner of  claim 7 , wherein the antibiosis and sterilization material is coated with a chemical vapor deposition (CVD) method.
