Abstract

In this shower apparatus, a part of an internal space thereof closer to the outer circumference thereof than an aeration unit is defined as a plurality of small spaces, and all of the small spaces have a uniform channel resistance.

First claim

What is claimed is:

1. A shower apparatus that discharges aerated bubbly water, comprising:
a water supply unit that supplies water;
a single throttle unit disposed downstream of the water supply unit, the single 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 single throttle unit to radially eject the water, as a single main water stream, toward an outer circumference of the shower apparatus;
an aeration unit disposed closer to the outer circumference than the single throttle unit and provided with an opening for aerating water ejected through the single 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;
a pulsation imparting unit, which has a swirl chamber facing the opening, provided in the vicinity of the single main water stream, that periodically changes a traveling direction of the single main water stream by a swirl formed in the swirl chamber, and thereby periodically changes an amount of air mixed into the single main water stream, so as to impart the bubbly water with pulsation; and
a plurality of partition walls which define a part of an internal space closer to the outer circumference than the opening and the swirl chamber as a plurality of small spaces,
wherein the plurality of small spaces is configured such that all of the small spaces have a uniform channel resistance, and
wherein the partition walls extend from the outer circumference of the shower apparatus towards the swirl chamber such that streams of the bubbly water that flow into the small spaces do not interfere with one another.

2. The shower apparatus according to claim 1 , wherein, when seen along a direction in which the bubbly water is discharged from the nozzle holes, all of the small spaces have a uniform distance that covers from a passage, through the swirl chamber, of water ejected from the single throttle unit to an arrival of the water at an inlet of each of the small spaces.

3. The shower apparatus according to claim 2 , wherein all of the small spaces have a uniform total opening area of the nozzle holes that communicate the small space with an external space.

4. The shower apparatus according to claim 3 , wherein all of the small spaces have a uniform shape.
