    摘要： A filtration device with filters that can be backwashed with purified water switches between water purification, first backwashing, and second backwashing modes, depending on a pivot position of a valve. During the first backwashing mode, while a tap water inlet is in communication with a second tap water passage port, first and second purified water passage ports are blocked from communication with a purified water outlet, so purified water from a second filter flows backward through a first filter and is discharged from a drain water outlet. During the second backwashing mode, while the tap water inlet is in communication with a first tap water passage port, first and second purified water passage ports are blocked from communication with the purified water outlet, so purified water from the first filter flows backward through the second filter and is discharged from the drain water outlet.

    摘要： Provided is a filtration device with a plurality of filters that can be backwashed with purified water with a simple operation. The filtration device 1 switches between a water purification mode, a first backwashing mode, and a second backwashing mode, depending on a pivot position of a valve 6. During the first backwashing mode, while a tap water inlet 51 is in communication with a second tap water passage port 53, first and second purified water passage ports 54, 55 are blocked from communication with a purified water outlet 56, so that purified water from a second filter 3 flows backward through a first filter 2 and is discharged as drain water from a drain water outlet 57. During the second backwashing mode, while the tap water inlet 51 is in communication with a first tap water passage port 52, first and second purified water passage ports 53, 54 are blocked from communication with the purified water outlet 56, so that purified water from the first filter 2 flows backward through the second filter 3 and is discharged as drain water from the drain water outlet 57.
