Shower apparatus

摘要

A shower apparatus F1 includes a water supply unit 21; a throttle unit 22 installed downstream of the water supply unit 21 and adapted to eject passing water downstream; an aeration unit 23 provided with an opening 231 adapted to produce bubbly water by aerating the water ejected through the throttle unit 22; and a nozzle unit 24 provided with a plurality of nozzle holes 243 adapted to discharge the bubbly water, wherein a virtual water ejection straight line obtained by extending an ejection direction of the water ejected through the throttle unit 22 reaches a location where the nozzle holes 243 are formed, without interfering with inner walls of the aeration unit 23 and the nozzle unit 24.

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 and adapted to make a cross sectional area of a flow channel smaller than the water supply unit and thereby eject passing water downstream; an aeration unit installed downstream of the throttle unit and provided with an opening adapted to produce the bubbly water by aerating the water ejected through the throttle unit; a nozzle unit installed downstream of the aeration unit and provided with a plurality of nozzle holes adapted to discharge the bubbly water by being formed along an ejection direction of the water ejected through the throttle unit; and rod-shaped projections configured to project into the nozzle unit, wherein the throttle unit is made up of a plurality of throttle channels arranged side by side; each of virtual water ejection straight lines obtained by extending the ejection direction of the water ejected from each of the plurality of throttle channels to a position interfering with an inner wall of a flow channel which is formed downstream of the throttle unit does not interface with the inner walls of the aeration unit and a nozzle face in which the nozzle holes are formed; the bubbly water is produced when the water ejected from the throttle unit plunges into an air-liquid interface between air and the water temporarily pooled in the aeration unit and nozzle unit; and the rod-shaped projections are adapted to divide a water stream generated by the nozzle unit by the water plunging into the air-liquid interface into substreams.
