Title (EN) FILTRATION DEVICE
(FR) DISPOSITIF DE FILTRATION
(JA) 濾過装置
Abstract:
(EN) Provided is a filtration device having a plurality of filters in which the filters can be backwashed by purified water in a simple operation. The filtration device (1) switches between a water purification mode, a first backwashing mode, and a second backwashing mode in accordance with the pivot position of a valve element (6). During the first backwashing mode, a source water inlet (51) is in communication with a second source water through-port (53), and first and second purified water through-ports (54, 55) are blocked from communication with a purified water outlet (56), whereby purified water from a second filter (3) is backwashed through the first filter (2) and the drain water is discharged from a drain water outlet (57). During the second backwashing mode, the source water inlet (51) is in communication with a first source water through-port (52), and first and second purified water through-ports (53, 54) are blocked from communication with the purified water outlet (56), whereby purified was from the first filter (2) is backwashed through the second filter (3), and the drain water is discharged from the drain water outlet (57).
(FR) L'invention concerne un dispositif de filtration ayant une pluralité de filtres dans lequel les filtres peuvent être lavés à contre-courant par de l'eau purifiée en une opération simple. Le dispositif de filtration (1) commute entre un mode de purification d'eau, un premier mode de lavage à contre-courant et un second mode de lavage à contre-courant conformément à la position de pivot d'un élément soupape (6). Pendant le premier mode de lavage à contre-courant, une entrée d'eau de source (51) est en communication avec un second orifice traversant d'eau de source (53), et des premier et second orifices traversants d'eau purifiée (54, 55) sont bloqués d'une communication avec une sortie d'eau purifiée (56), ce par quoi de l'eau purifiée provenant d'un second filtre (3) est lavée à contre-courant à travers le premier filtre (2) et l'eau de drainage est déchargée de la sortie d'eau de drainage (57). Pendant le second mode de lavage à contre-courant, l'entrée d'eau de source (51) est en communication avec un premier orifice traversant d'eau de source (52), et des premier et second orifices traversants d'eau purifiée (53, 54) sont bloqués d'une communication avec la sortie d'eau purifiée (56), ce par quoi de l'eau purifiée provenant du premier filtre (2) est lavée à contre-courant à travers le second filtre (3) et l'eau de drainage est déchargée de la sortie d'eau de drainage (57).
(JA)  濾過器を複数設けた濾過装置において、簡単な操作で浄水による濾過器の逆洗が可能となるものを提供する。この濾過装置1は、弁体6の回動位置に応じて、浄水モードと第1の逆洗モードと第2の逆洗モードが切り換えられ、第1の逆洗モードのときには、原水流入口51は第2の原水通過口53に連通し、第1及び第2の浄水通過口54、55は浄水流出口56への連通が遮断されることによって、第2の濾過器3からの浄水が第1の濾過器2を逆流して排水が排水流出口57から排出され、第2の逆洗モードのときには、原水流入口51は第1の原水通過口52に連通し、第1及び第2の浄水通過口53、54は浄水流出口56への連通が遮断されることによって、第1の濾過器2からの浄水が第2の濾過器3を逆流して排水が排水流出口57から排出される。
