Sterilizing-water generation device

Abstract

Provided is a sterilizing-water generation device which is characterized by being provided with: a hypochlorous acid-containing water generation unit which electrolyzes tap water to generate hypochlorous acid-containing water; a bactericidal-metal-ion water generation unit provided with electrodes which electrolyze tap water to elute bactericidal metal ions into the tap water; a water discharge unit which discharges the hypochlorous acid-containing water and / or the water including the bactericidal metal ions; and a control unit which controls operation of the hypochlorous acid-containing water generation unit and the bactericidal-metal-ion water generation unit. The sterilizing-water generation device is further characterized in that, in cases when the concentration of the hypochlorous acid in the hypochlorous acid-containing water is relatively low, the concentration of the bactericidal metal ions in the water including the bactericidal metal ions is relatively high.

Description

technical field [0001] The aspects of the present invention generally relate to a sterilizing water generator. Background technique [0002] For example, in order to use a small amount of sterilizing water at a low concentration (concentration that suppresses the influence on the human body) to sterilize objects that are difficult to stagnate in sterilizing water and have a lot of dirt (such as the floor of the bathroom flushing place, etc.), It is preferable to spit out the water containing hypochlorous acid and the water containing bactericidal metal ions onto the object. For example, there is a functional water generator including a bactericidal metal addition unit for adding bactericidal metal ions to feed water, and a hypochlorous acid addition unit for adding hypochlorous acid to feed water (Patent Document 1). [0003] Usually, the water containing hypochlorous acid is quick-acting and can destroy the cell membrane of bacteria in a short time. On the other hand, it i...

AI Technical Summary

Problems solved by technology

Therefore, when the amount of chloride ions is small, the concentration of hypochlorous acid becomes low, and the destruction of the cell membrane of bacteria becomes insufficient in some cases.

When the destruction of the cell membrane of the bacteria is insufficient, the water containing the bactericidal metal ion cannot reach the nucleus of the bacteria, and there is a problem that the sterilization effect becomes insufficient.
