Abstract
(EN) The present invention provides a water-purifying apparatus comprising: a reverse osmosis filter (110) for filtering raw water in a reverse osmosis type, the reverse osmosis filter (110) being divided into a filtering side (112a) and a non-filtering side (112b) with reference to a built-in reverse osmosis membrane (111); a pump unit (120) provided on a raw-water line (130) connected to the front-end side of the reverse osmosis filter (110) so as to move raw water toward the non-filtering side (112b); a purified-water discharging line (140) connected to the filtering side (112a) of the reverse osmosis filter (110) such that filtered purified-water is discharged therethrough; a purified-water extracting valve (142) provided on the purified-water discharging line (140) so as to open/close the purified-water discharging line (140); a domestic-water discharging line (150) connected to the non-filtering side (112b) of the reverse osmosis filter (110) so as to discharge unfiltered domestic water from the reserve osmosis filter (110); a domestic-water discharging valve (152) provided on the domestic-water discharging line (150) so as to open/close the domestic water-discharging line (150); and a control unit (160) for controlling operations of the pump unit (120) and the domestic-water discharging valve (152). The control unit (160) closes the domestic-water discharging valve (152) in a transient state, until the pressure difference between the front-end side of the pump unit (120) and the rear-end side thereof reaches a normal state since closure of the purified-water extracting valve (142) and initial operation of the pump unit (120).
(FR) La présente invention concerne un appareil de purification d'eau comprenant : un filtre d'osmose inverse (110) pour filtrer de l'eau brute dans un type d'osmose inverse, le filtre d'osmose inverse (110) étant divisé en un côté filtrant (112a) et un côté non filtrant (112b) en référence à une membrane d'osmose inverse intégrée (111) ; une unité de pompe (120) disposée sur une conduite d'eau brute (130) reliée au côté d'extrémité avant du filtre d'osmose inverse (110) de façon à déplacer l'eau brute vers le côté non filtrant (112b) ; une conduite d'évacuation d'eau purifiée (140) reliée au côté filtrant (112a) du filtre d'osmose inverse (110) de telle sorte que l'eau purifiée filtrée est évacuée à travers celle-ci ; une vanne d'extraction d'eau purifiée (142) disposée sur la conduite d'évacuation d'eau purifiée (140) de façon à ouvrir/fermer la conduite d'évacuation d'eau purifiée (140) ; une conduite d'évacuation d'eau domestique (150) reliée au côté non filtrant (112b) du filtre d'osmose inverse (110) de façon à évacuer l'eau domestique non filtrée du filtre d'osmose de réserve (110) ; une vanne d'évacuation d'eau domestique (152) disposée sur la conduite d'évacuation d'eau domestique (150) de façon à ouvrir/fermer la conduite d'évacuation d'eau domestique (150) ; et une unité de commande (160) pour commander les opérations de l'unité de pompe (120) et de la vanne d'évacuation d'eau domestique (152). L'unité de commande (160) ferme la vanne d'évacuation d'eau domestique (152) dans un état transitoire, jusqu'à ce que la différence de pression entre le côté d'extrémité avant de l'unité de pompe (120) et le côté d'extrémité arrière de celui-ci atteigne un état normal depuis la fermeture de la vanne d'extraction d'eau purifiée (142) et le fonctionnement initial de l'unité de pompe (120).
