Title
(DE) DUSCHKOPF MIT GEMISCHTEN STRAHLEN
(EN) CONVERGING SPRAY SHOWERHEAD
(FR) POMME DE DOUCHE A PULVERISATION CONVERGENTE
Abstract
(EN)
Showerheads with two or more nozzles configured to deliver water streams that converge at one or more regions. Prior to convergence, the converging water streams may generally retain a recognizable shape determined by the type of nozzle. Upon convergence, at least portions of the converging water streams may substantially disperse into multiple individual water droplets. The nozzles, or a face plate or other components joining the nozzles to a showerhead, may be selectively movable to selectively move the region or regions of convergence closer to or further away from the showerhead, or to convert the nozzles from delivering converging streams to delivering non-converging streams or vice versa. Some showerheads may further include other nozzles for delivering water from the showerhead in other modes, such a high pressure mode, a pulsating mode, a mist mode, and so on.

(FR)
L'invention concerne des pommes de douche munies de deux ou plusieurs buses configurées pour acheminer des jets d'eau qui convergent en une ou plusieurs régions. Avant toute convergence, les jets d'eau convergents peuvent généralement retenir une forme reconnaissable déterminée par le type de buse. Lors de la convergence, au moins des parties des jets d'eau convergents peuvent sensiblement se disperser en de multiples gouttelettes d'eau individuelles. Les buses, ou un plateau ou autres composants raccordant les buses à une pomme de douche, peuvent être déplacées de manière sélective pour déplacer de manière sélective la région ou les régions de convergence plus près ou plus loin de la pomme de douche, ou pour convertir les buses de l'acheminement de jets convergents à l'acheminement de jets non convergents ou vice versa. Certaines pommes de douche peuvent par ailleurs comprendre d'autres buses pour acheminer l'eau en provenance de la pomme de douche selon d'autres modes, tels qu'un mode de haute pression, un mode d'impulsion, un mode d'atomisation, etc.
