Patent ID: 7416326

Claim:
An apparatus for manufacturing sterilizing water, in which sterilizing water is manufactured by mixing an acid solution consisting of hydrochloric acid or acetic acid or a mixture thereof and a chlorine-based solution consisting of sodium hypochlorite or chlorine dioxide or a mixture thereof with water, comprising: a feeder provided with a first flow path, in which the acid solution is fed to a part of a water flow to produce a dilute acid solution, and a second flow path, in which the chlorine-based solution is fed to a remainder of the water flow to produce a dilute chlorine-based solution, the feeder feeding the acid solution and the chlorine-based solution by suction utilizing a negative pressure produced in water flowing in the first and second flow paths, absent a pump; a mixer comprising a plurality of mixing blades, the mixer being arranged on the downstream side of the first and second flow paths to mix the dilute acid solution sent through the first flow path with the dilute chlorine-based solution sent through the second flow path; and a separation wall including a planar member extending along a longitudinal axis of the first and second flow paths that is configured to separate the first and second flow paths, wherein a downstream end portion of the separation wall is connected to the plurality of mixing blades.
