摘要： A filter assembly includes a filter holder into which a part of the filter is insertable, and a lock mounted to the filter holder and configured to lock and release the filter to and from the filter holder. The lock includes a guide coupled to the filter holder and configured to be linearly movable to transmit a force in a direction into which the filter is inserted, a pusher configured to transmit a force in a direction opposite to the direction, into which the filter is inserted, by an elastic member, a stopper rotatably received in the pusher to be arranged between the pusher and the guide, and configured to linearly move the filter holder by being linearly moved by the guide and the pusher, and a cam configured to lock and release the filter to and from the filter holder by guiding rotation and linear movement of the stopper.

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.
