Filter assembly

A filter assembly comprising:

• an outer casing forming an exterior of the filter assembly;
• a plurality of filters to be arranged in the outer casing, and the plurality of filters comprising a first filter, a second filter, and a third filter;
• a pipe member to be connected to the first filter, the second filter, and the third filter, and the pipe member comprising:
• an inlet flow path which comprises:
• a first inlet flow path which while connected to the first filter allows water to be introduced into the first filter,
• a second inlet flow path which while connected to the second filter allows water to be introduced into the second filter,
• a third inlet flow path which while connected to the third filter allows water to be introduced into 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 which are parallel to each other, and
• an outlet flow path which comprises:
• a first outlet flow path which while connected to the first filter allows water to be discharged from the first filter, and
• a second outlet flow path which while connected to the second filter allows water to be discharged from the second filter;
• an inner casing arranged outside the first filter, the second filter, and the third filter to fix the first filter, the second filter, and the third filter;
• a residual water hole arranged on the inner casing;
• a support member, including an insertion protrusion, arranged under the inner casing and coupled to the inner casing;
• and
• a water collecting tray, slidable along the support member, to be introduced into the outer casing between the inner casing and the support member and withdrawn from the outer casing, the water collecting tray being below the residual water hole such that residual water from the first filter, the second filter, and the third filter is discharged through the residual water hole and collected in the water collecting tray,
• wherein the water collecting tray comprises a guide groove recessed from a lower surface of the water collecting tray, and the support member including the insertion protrusion which is inserted into the guide groove, and
• wherein water discharged from the first outlet flow path is guided with water discharged from the second outlet flow path and introduced into the third inlet flow path,
• a mounting member coupleable to one end of the first filter, the second filter, and the third filter;
• and
• a door bracket provided to cover another end of the first filter, the second filter, and the third filter, the door bracket comprising a door block formed to protrude from a wall of the door bracket provided to cover the another end of the first filter, the second filter, and the third filter, so as to face the another end of at least one of the first filter, the second filter, and the third filter in a position in which the first filter, the second filter, and the third filter are coupled to the mounting member,
• wherein the first filter, the second filter, and the third filter are covered by the door bracket in the position, and
• wherein the guide groove formed in a position corresponding to the door block which operates as a door guide to allow the door block to guide withdrawal of the water collecting tray.
