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, and all of the small spaces have a uniform ratio between a channel cross-sectional area at an inlet portion of each of the small spaces and a total opening area of nozzle holes that communicate the small space with an external space such that backflow water CF that returns from the respective small spaces consistently has a uniform flow rate at any point in time among the streams of the backflow water CF.

Abstract: The present invention aims to provide a water faucet which allows a large space to be secured above the washing area and yet can deliver a high washing performance by landing streams or waterdrops having a large cross-sectional area evenly on a piece to wash. This water faucet includes a flow velocity changing part which changes the flow velocity of the stream discharged from each of multiple water spray holes such that the cross-sectional area of the stream changes with time. The multiple water spray holes are disposed at intervals such that, when the cross-sectional area of one stream discharged from one water spray hole exceeds a predetermined size, the one stream is merged with one of the other streams discharged from the multiple other water spray holes adjacent to the one water spray hole, and such that the one of the other streams with which the one stream merges changes with time.

Abstract translation: 本发明的目的在于提供一种水龙头，其允许在洗涤区域上方具有大的空间，并且可以通过将具有大的横截面积的流或水滴均匀地落在一块上来洗涤，从而可以提供高的洗涤性能。 该水龙头包括流量变化部，其改变从多个喷水孔排出的流的流速，使得流的横截面积随时间而变化。 多个喷水孔的间隔设置成使得当从一个喷水孔排出的一个流的横截面积超过预定尺寸时，该一个流与从多个其它水喷雾排出的其它流中的一个流合并 与一个喷水孔相邻的孔，并且使得与一个流合并的其它流中的一个随时间变化。
