Description

上述した課題を解決するために、本発明は、複数の吐水口の各々から湯水を往復振動させながら吐出するシャワーヘッドであって、シャワーヘッド本体と、このシャワーヘッド本体に設けられ、供給された湯水を往復振動させながら吐出する複数の振動発生素子と、を有し、各振動発生素子は、シャワーヘッド本体から供給された湯水が流入する給水通路と、この給水通路の流路断面の一部を閉塞するように、給水通路の下流側端部に配置され、給水通路によって導かれた湯水が衝突することで、その下流側に交互に反対回りの渦を発生させる湯水衝突部と、給水通路の下流側に設けられ、湯水衝突部により形成された渦を成長させながら導く渦列通路と、この渦列通路の下流側に設けられ、渦列通路によって導かれた渦列を含む湯水を整流して吐出させる整流通路と、を有し、渦列通路の下流側には、流路断面積が下流側に向かって縮小するように、対向する一対の壁面がテーパして設けられたテーパ部分が、整流通路よりも長い範囲に亘って設けられていることを特徴としている。
In order to solve the above-described problems, the present invention is a shower head that discharges hot water from each of a plurality of water outlets while reciprocatingly vibrating, and is provided and supplied to the shower head main body and the shower head main body. A plurality of vibration generating elements that discharge while reciprocating the hot and cold water, and each vibration generating element includes a water supply passage through which hot water supplied from the shower head body flows, and a part of a flow path cross section of the water supply passage A hot water collision portion that is disposed at the downstream end of the water supply passage so as to close the water supply water and collides with hot water guided by the water supply passage, and alternately generates a vortex in the opposite direction on the downstream side, and the water supply passage the provided downstream, and Uzuretsu passage for introducing while growing the vortex formed by the hot water collision part, the vortex street passage downstream provided et al are of the hot water containing the vortex that is guided by the vortex streets passage Rectification A taper portion provided with a pair of opposing wall surfaces tapered so that the cross-sectional area of the flow path is reduced toward the downstream side. , And is provided over a longer range than the rectifying passage.

Claims
