Shower apparatus

A shower apparatus for discharging aerated bubbly water, comprising:

• a water supply unit adapted to supply water;
• a throttle unit which, being installed downstream of the water supply unit, comprises a plurality of throttle channels installed in parallel so as to make a total cross sectional area of the plurality of throttle channels smaller than a cross sectional area of a water passage in 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;
• and
• a nozzle unit installed downstream of the aeration unit and provided with a plurality of nozzle holes being orthogonal with respect to the ejection direction and adapted to discharge the bubbly water by being formed along an ejection direction of the water ejected through the throttle unit;
• wherein at least some of the plurality of throttle channels are arranged side by side in a lateral direction along a nozzle face in which the plurality of nozzle holes are provided,
• wherein water is ejected from the plurality of throttle channels such that the speed of the water ejected from the throttle channels installed on the center side will be faster than the speed of the water ejected from the throttle channels installed on the lateral side,
• wherein the cross sectional area of the water passage in the downstream side of the water supply unit is larger than the cross sectional area of the water passage in the upstream side of the water supply unit, such that a lateral length from the throttle channel formed at one end in the lateral direction to the throttle channel formed at the other end in the lateral direction is longer than a water passage diameter at the water supply unit, and
• wherein none of virtual water ejection straight lines which are orthogonal to an extending direction of the nozzle holes and drawn from the plurality of throttle channels between the throttle channels and the nozzle unit downstream of the ejection direction intersects with an internal wall of the shower apparatus corresponding to the water passage arranged between the throttle channels and the nozzle unit.
