1. A shower apparatus that discharges aerated bubbly water, comprising:
a water supply unit that supplies water; a throttle unit disposed downstream of the water supply unit, the throttle unit making a channel cross-sectional area smaller than that of the water supply unit and thereby increasing a flow velocity of water passing through the throttle unit to radially eject the water, as a main water stream, toward an outer circumference of the shower apparatus; an aeration unit disposed closer to the outer circumference than the throttle unit and provided with an opening for aerating water ejected through the throttle unit so as to produce bubbly water; a water discharge unit disposed further closer to the outer circumference than the aeration unit and provided with a plurality of nozzle holes for discharging the bubbly water; and a pulsation imparting unit that periodically changes a traveling direction of the main water stream and thereby periodically changes an amount of air mixed into the main water stream, so as to impart the bubbly water with pulsation, wherein a part of an internal space closer to the outer circumference than the aeration unit is defined as a plurality of small spaces, and after the bubbly water produced in the aeration unit flows into the respective small spaces, the bubbly water is discharged from the nozzle holes, wherein the pulsation imparting unit receives, in a swirl chamber, backflow water that returns from the small respective spaces toward the throttle unit so as to form a swirl in the vicinity of the main water stream, such that a negative pressure produced inside the swirl periodically changes the traveling direction of the main water stream, and wherein all of the small spaces have a uniform channel resistance. |
