Abstract
The present invention provides a shower apparatus that allows the user to have a shower stream with a voluminous feel, even when a small volume of water is discharged, and also with a stimulus sensation arising from water being discharged in a pulsating manner. A shower apparatus F1 periodically changes the volume of air taken into an aeration unit 43 by oscillating a main water stream ejected toward the aeration unit 43 from a throttle unit 42 in a direction crossing the direction of the ejection, so that the bubbly water discharged from a water discharge unit 44 creates a pulsating shower stream.
Claims10
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 cross sectional area of a flow channel smaller than that of the water supply unit and thereby increasing a flow velocity of water passing through the throttle unit to eject the water downstream as a main water stream;
- an aeration unit disposed downstream of the throttle unit and provided with an opening for aerating the main water stream to produce bubbly water;
- a water discharge unit disposed downstream of the aeration unit and provided with a plurality of nozzle holes for discharging the bubbly water;
- and
- a side-water-stream producing unit that produces a side water stream traveling in a direction different from that of the main water stream,
- wherein the traveling direction of the main water stream is changed periodically by the effect of the side water stream, so as to change a volume of air mixed into the main water stream in the aeration unit.
