Title (EN) WATER PURIFICATION DEVICE AND WATER PURIFIER FOR HOUSEHOLD USE
(FR) DISPOSITIF DE PURIFICATION D'EAU ET PURIFICATEUR D'EAU À USAGE DOMESTIQUE
(JA) 浄水装置および家庭用浄水器
Abstract:
(EN) Provided is a water purification device wherein water purification performance can be greatly switched in a single water purification device. A water purification device (1A) is provided with: a RO membrane filter (2b) and a RO membrane filter (3b); and a switching mechanism (4) for switching a flow path to a series state and a parallel state. In the series state, raw water (11) passes through the RO membrane filter (2b) and the RO membrane filter (3b) sequentially, and in the parallel state, part of the raw water (11) passes through the RO membrane filter (2b) and the other part passes through the RO membrane filter (3b).
(FR) L'invention concerne un dispositif de purification d'eau dans lequel la performance de purification d'eau peut être fortement commutée dans un seul dispositif de purification d'eau. Ce dispositif de purification d'eau (1A) comprend: un filtre à membrane RO (2b) et un filtre à membrane RO (3b); et un mécanisme de commutation (4) pour commuter un trajet d'écoulement à un état série et un état parallèle. Dans l'état série, de l'eau brute (11) passe séquentiellement à travers le filtre à membrane RO (2b) et le filtre à membrane RO (3b), et dans l'état parallèle, une partie de l'eau brute (11) passe à travers le filtre à membrane RO (2b) et l'autre partie passe à travers le filtre à membrane RO (3b).
(JA) 1つの浄水装置の中で、浄化性能を大きく切り替えることができる浄水装置を提供する。浄水装置(1A)は、RO膜フィルタ(2b)およびRO膜フィルタ(3b)と、直列状態と並列状態とに流路を切り替える切替機構(4)とを備えている。直列状態では、原水(11)がRO膜フィルタ(2b)およびRO膜フィルタ(3b)を順次通過し、並列状態では、原水(11)の一部がRO膜フィルタ(2b)を通過し、他の一部がRO膜フィルタ(3b)を通過する。
