Shower apparatus

摘要

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.

主权项

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 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, the side-water-stream producing unit has a swirl chamber located such that the swirl chamber and the opening are on opposite sides of the main water stream, the swirl chamber is formed as a concave portion for producing the side water stream as a swirled stream that generates negative pressure to attract the main water stream, and the throttle unit is configured to eject the main water stream between the opening and the swirl chamber such that the main water stream prevents the air taken in from the opening from flowing into the side water stream.
