Abstract
(EN)
The purpose of the present invention is to realize a water purification device capable of obtaining purified water even when a solenoid valve is not operated at the time of a power failure. A water purification device (1) has a solenoid valve (31) that is provided in a main passage (50) and that opens and closes the main passage (50), and further includes: a bypass passage (32) that bypasses the solenoid valve (31); and a passage switching mechanism (33) that opens and closes the bypass passage (32) without using electric power.
(FR)
La présente invention a pour but de pourvoir à un dispositif de purification d'eau pouvant obtenir de l'eau purifiée même lorsqu'une électrovanne n'est pas actionnée au moment d'une panne d'électricité. Le dispositif de purification d'eau (1) comprend une électrovanne (31) agencée dans un passage principal (50) et destinée à ouvrir et à fermer le passage principal (50), et comprend en outre : un passage de dérivation (32) permettant de contourner l'électrovanne (31); et un mécanisme de commutation de passage (33) destiné à ouvrir et à fermer le passage de dérivation (32) sans utiliser de l'électricité.
(JA)
停電時に電磁弁が作動しなくても浄水が得られる浄水装置を実現すること。浄水装置(1)は、主経路(50)上に当該主経路(50)の開閉を行う電磁弁(31)設け、さらに、当該電磁弁(31)を迂回するバイパス経路(32)と、当該バイパス経路(32)を無電力で開閉する経路切替機構(33)と、を備えている。
