摘要： A filter assembly comprises an outer casing, filters and a pipe member connected to first, second and third filters and comprising an inlet flow path and an outlet flow path. The inlet flow path comprises a first inlet flow path connected to the first filter, a second inlet flow path connected to the second filter, a third inlet flow path connected to the third filter, and an inflow member comprising a branch point to allow water to flow in parallel through the first inlet flow path and the second inlet flow path. The outlet flow path comprises a first outlet flow path for water to be discharged from the first filter, and a second outlet flow path for water to be discharged from the second filter. Water discharged from the first outlet flow path from the second outlet flow path is guided and introduced into the third inlet flow path.

摘要： A water purifier and a filter for the water purifier are provided. The water purifier includes a raw water flow path formed to bring in raw water from the outside, a purified water flow path connected to the raw water flow path for the raw water to flow in a first direction, a filter located in the purified water flow path to filter the raw water, a bypass flow path branched from the purified water flow path for the raw water to bypass the filter and connected to the purified water flow path on a downstream side of the filter in the first direction, a washing flow path branched from the bypass flow path and connected to the purified water flow path on a downstream side of the filter in the first direction, and a drain flow path connected to the filter to guide the raw water flowing into the filter to a second direction. The filter includes a raw water inlet through which raw water flowing in the first direction is introduced, a purified water outlet through which purified water filtered is released, and a drain outlet through which wash water having washed the filter is discharged.

摘要： Disclosed is a water purifier that includes a deionization device for purifying water with electric power, and a controller electrically connected to the deionization. The deionization device includes a housing and a plurality of electric filters arranged in a plurality of isolation rooms formed in the housing. The controller operates the plurality of electric filters by dividing the plurality of electric filters into a plurality of electric adsorption filters which adsorb ionic materials and at least one electric resting filter which remains in a standby state during a water purification operation, and restart the water purification operation or perform a recycling operation to recycle the plurality of electric filters, depending on whether a restart command for the water purification operation is input within a preset waiting time from a point in time when the water purification operation is stopped.
