The object of the invention is to give a coloured, temperature-dependent appearance to the water flowing out of a hot-water fitting. For that purpose, three temperature ranges are formed and a colour is associated with each of the temperature ranges. The three ranges correspond to too cold, too hot and desired temperature ranges. A lever (4) is actuated to cause a water jet (20) to flow out of the fitting. Depending on the position of the lever (4), only cold water, only hot water or mixed proportions of cold and hot water flow into the mixing chamber (7). Depending on the temperature measured in the mixing chamber (7), a control block (13) drives diodes (17) arranged at the outlet of the hot-water fitting and having a colour which corresponds to the temperature range in question, causing the diodes to emit light. The water jet (20) flowing past the diodes (17) is illuminated with said colour. The user of the fitting can recognise the water temperature from the coloured appearance of the water jet (20) and if necessary correct it by actuating the lever (4).

L'invention vise à donner un aspect coloré à l'eau coulant d'un robinet d'eau chaude en fonction de sa température. A cet effet, on détermine trois zones thermiques associées chacune à une couleur, ces zones thermiques étant le trop froid, le trop chaud et la température désirée. Un levier (4) sert à la déclencher un jet d'eau (20) sortant du robinet. En fonction de la position de ce levier (4) s'écoule soit seulement de l'eau froide, soit seulement de l'eau chaude, soit un mélange d'eau froide et chaude dans le mélangeur (7). Sur la base de la température mesurée dans ce mélangeur (7), un bloc de réglage (13) commande des diodes (17) d'une couleur correspondant à la zone thermique pour les allumer, ces diodes étant disposées au niveau de l'écoulement du robinet d'eau chaude. Le jet d'eau (20) qui s'écoule au niveau de ces diodes (17) s'éclaire alors de la couleur correspondante. Ainsi, l'utilisateur peut reconnaître la température du jet d'eau (20) sur la base de sa couleur et effectuer une correction éventuelle en actionnant le levier (4).
