<P>PROBLEM TO BE SOLVED: To provide a water discharge device capable of discharging bubble-mixed water having an increased air bubble mixing ratio at a low flow rate stage, and capable of preventing bubble-mixed water of which total amount seems to largely exceed a water quantity intended by a user at a high flow rate stage. <P>SOLUTION: A discharge port cap BC as a water discharge device is configured so that, when the flow rate of water inflow from an inflow entrance 101 exceeds a prescribed flow rate, a mixing ratio adjustment part 302 suppresses an increase in flow speed of water jetted from a plurality of jet holes 304 by decreasing the opening area of an air hole 204 and forming a route through which water flows to the downstream side of a decompression plate 301 as a bypass channel other than a main channel passing through the plurality of jet holes 304, and executes composite adjustment operation to suppress an increase in mixing ratio. <P>COPYRIGHT: (C)2012,JPO&INPIT |
