<p>PROBLEM TO BE SOLVED: To prevent a risk of leakage of an acid aqueous solution and a chlorine-containing aqueous solution if an acid aqueous solution container and a chlorine-containing aqueous solution container fall down, and to reduce the size of a water sterilizer.SOLUTION: A water sterilizer for producing sterile water by mixing an acid aqueous solution 22a and a chlorine-containing aqueous solution 23a into water includes: an acid aqueous solution mixer 26 which mixes the acid aqueous solution 22a into the water by sucking the solution from an acid aqueous solution container 22 by negative pressure generated using a water flow; and a chlorine-containing aqueous solution mixer 27 which mixes the chlorine-containing aqueous solution 23a into the water by sucking the solution from a chlorine-containing solution container 23 by negative pressure generated using a water flow. The obtained acid aqueous solution-mixed solution 24a and the obtained chlorine-containing solution-mixed solution 25a are mixed to produce sterile water. The acid aqueous solution container 22 and the chlorine-containing solution container 23 are each sealed by a lid having a check valve which, when the acid aqueous solution 22a or the chlorine-containing aqueous solution 23a is sucked, allows necessary air to be taken in from outside but prevents the outflow of the aqueous solution from inside.</p> |
