Abstract
(EN)
A shower device having a microbubble generating mechanism. The microbubble generating mechanism is provided with a collision member (22) projecting from the inner surface of a flow passage wall (25), and also with a gap forming section (23) formed in a flow passage (FP) so as to be opposed to the front end, with respect to the direction of the projection, of the collision member (22). A bypassing flow passage (251) is formed between the outer peripheral surface of the collision member (22) and the inner surface of the flow passage wall (25). A restriction gap (21G) is formed between the collision member (22) and the gap forming section (23). The restriction gap (21G) restricts flow of water so that the water flows through the restriction gap (21G) at a lower flow rate and a higher flow speed than when flowing through the water bypassing flow passage (251). Owing to the construction above, the microbubble generating mechanism can generate a sufficient amount of bubbles without using a complex air-liquid mixing mechanism and can break up bubbles into finer microbubbles with greatly enhanced effect. As a result, the microbubble generating mechanism can generate a large amount of bubbles, which are in a micro bubble region or a micro-nano bubble region, at a level which has not been achieved by conventional products.

L'invention concerne un dispositif de douche équipé d'un mécanisme de production de microbulles. Ledit mécanisme de production de microbulles est pourvu d'un élément de collision (22) saillant de la surface intérieure d'une paroi de passage d'écoulement (25), et d'une section formant un espace (23) dans un passage d'écoulement (FP) de façon à être opposé à l'extrémité avant, par rapport à la direction de la saillie, de l'élément de collision (22). Un passage d'écoulement de dérivation (251) est formé entre la surface périphérique extérieure de l'élément de collision (22) et la surface intérieure de la paroi du passage d'écoulement (25). Un espace de restriction (21G) est formé entre l'élément de collision et la section formant un espace (23). L'espace de restriction (21G) limite l'écoulement de l'eau de sorte que l'eau s'écoule traverse l'espace de restriction (21G) à un débit inférieur et à une vitesse d'écoulement plus élevée que lorsqu'elle traverse le passage d'écoulement de dérivation (251). Compte tenu de la construction précitée, le mécanisme de production de microbulles peut générer une quantité suffisante de bulles sans utiliser un mécanisme de mélange air-liquide complexe et briser les bulles en microbulles plus fines avec un effet fortement renforcé. Il en résulte que le mécanisme de production de microbulles peut générer une grande quantité de bulles, qui sont dans une région de micro bulles ou de micro-nano bulles, à un niveau que les produits classiques n'ont pas atteint.

シャワー本体50の流路壁部25の内面から突出する形で衝突部材22を設け、また、該流路FP内にて衝突部材22の突出方向先端部と対向するギャップ形成部23を設ける。そして、衝突部材22の外周面と流路壁部25の内面との間に水迂回流路部251を形成するとともに、衝突部材22と絞りギャップ形成部23との間には、水迂回流路部251よりも低流量かつ高流速となるように水流を絞りつつ通過させる絞りギャップ21Gを形成する。これにより、複雑な気液混合機構を用いずとも十分な量の気泡を発生でき、かつ、気泡の微細化効果が劇的に向上し、ひいてはマイクロバブル領域あるいはマイクロ・ナノバブル領域の気泡の発生量を、従来達成し得なかったレベルにまで高めることができる微細気泡発生機構付シャワー装置を提供する。
