Abstract:
1. A shower apparatus for discharging aerated bubbly water, comprising: a water supply unit adapted to supply water; a throttle unit installed downstream of the water supply unit, the throttle unit including one throttle channel, a total cross sectional area of the one throttle channel being smaller than a cross sectional area of a channel of the water supply unit and the throttle unit ejecting passing water downstream; an aeration unit installed downstream of the throttle unit and the aeration unit being provided with an opening adapted to produce the bubbly water by aerating the water ejected through the throttle unit; and a nozzle unit installed downstream of the aeration unit, the nozzle unit including a nozzle face having a plurality of nozzle holes adapted to discharge the bubbly water, the plurality of nozzle holes being formed along an ejection direction of the water, continuous with a running direction of the water ejected through the throttle unit, the one throttle channel at a downstream side end of the throttle unit being formed with a slit, the slit opening all around in a radial direction which is perpendicular to the running direction of the water supplied from the water supply unit, the one throttle channel being configured to eject one sheet-like stream of water all around in a radial direction, said radial direction being perpendicular to the running direction of the water supplied by the water supply unit and perpendicular to the plurality of nozzle holes; the sheet-like stream of water, which plunges into an air-liquid interface by involving air taken in through the opening of the aeration unit and thereby producing bubbly water, which is then discharged through the plurality of nozzle holes, where the air-liquid interface is an interface between air and water, the water having been temporarily pooled in the aeration unit and the nozzle unit, wherein the one sheet-like stream of water passes over the opening of the aeration unit as the water passes from the throttle unit and as the one-sheet like stream of water is formed by the slit opening.
