Spraying apparatus

Abstract

A spraying apparatus includes: a tank that stores a fluid; a spraying unit that is disposed at a lower portion of the tank, is connected to the tank through a flow path, and sprays the fluid that flows from the tank through the flow path by a weight of the fluid; a flow-path opening/closing unit that is disposed on the flow path between the tank and the spraying unit, and opens and closes the flow path; and an electrolyzing unit that is disposed between the flow-path opening/closing unit and the spraying unit, and electrolyzes at least a portion of the fluid. The fluid electrolyzed by the electrolyzing unit is supplied to the spraying unit by an opening and closing of the flow-path opening/closing unit.

       8 . A spraying apparatus comprising:
 a tank that stores a fluid;   a spraying unit that is disposed at a lower portion of the tank, is connected to the tank through a flow path, and sprays the fluid that flows from the tank through the flow path by a weight of the fluid;   a flow-path opening/closing unit that is disposed on the flow path between the tank and the spraying unit, and opens and closes the flow path; and   an electrolyzing unit that is disposed between the flow-path opening/closing unit and the spraying unit, and electrolyzes at least a portion of the fluid, wherein   the fluid electrolyzed by the electrolyzing unit is supplied to the spraying unit by an opening and closing of the flow-path opening/closing unit.   
   
   
       9 . The spraying apparatus according to  claim 8 , wherein a supply of power to the spraying unit is interlocked with an opening of the flow path of the fluid by the flow-path opening/closing unit. 
   
   
       10 . The spraying apparatus according to  claim 8 , wherein a supply of power to the electrolyzing unit is interlocked with an opening of the flow path of the fluid by the flow-path opening/closing unit. 
   
   
       11 . The spraying apparatus according to  claim 8 , wherein
 the electrolyzing unit includes as least two electrodes, and   the electrodes are disposed substantially perpendicular to a flow path direction.   
   
   
       12 . The spraying apparatus according to  claim 8 , further comprising a foam guide unit that guides foam generated in the flow path in a direction other than a direction toward the spraying unit.
