<p>This invention provides a functional water producing device and a functional water producing method that can produce a functional water, which can minimize the amount of soaps, detergents and the like used, produced by dissolving gas in a high concentration using pressured water or flowing water prepared, e.g., by tap water or a pump or a water head difference to produce water containing a large amount of fine gas bubbles, and can prepare regenerated water, various types of mineral water, sterile water, liquid fertilizer and the like by dissolving various metal ions according to need. The functional water producing device comprises a container (2) having a hollow part subjected to diameter reduction toward one of or both axial directions in the axis of rotational symmetry which has been formed in substantially rotational symmetry, a gas-liquid introduction hole (3) opened in a tangential direction in a peripheral wall part in the container (2), a gas-liquid spout hole (4), which is opened in the direction of the axis of rotational symmetry in the hollow part and is provided in the diameter reduced part in the hollow part, and a diffuser part (5) of which the flow passage sectional area is gently increased.</p> |
