Abstract

Disclosed is a water treatment apparatus that includes a head including an inlet portion into which water flows, an outlet portion from which water is discharged externally, and a connection portion connected to the inlet portion and the outlet portion, and a water treatment unit connected to the connection portion, including a plurality of water treatment sections, coupled to the head, and configured such that a portion of the water flowing into the inlet portion passes through the plurality of water treatment sections and sequentially, the remainder of the water passes through only a portion of the plurality of water treatment sections and, and the water flows to the outlet portion together.

First claim

1 . A water treatment apparatus comprising:
a head including an inlet portion into which water flows, an outlet portion from which water is discharged externally, and a connection portion connected to the inlet portion and the outlet portion; and a water treatment unit connected to the connection portion, including a plurality of water treatment sections and, coupled to the head, and configured such that a portion of the water flowing into the inlet portion passes through the plurality of water treatment sections sequentially, the remainder of the water passes through only a portion of the plurality of water treatment sections, and the water flows to the outlet portion together.

2 . The water treatment apparatus of claim 1 , wherein the head comprises:
a head unit including the inlet portion, the outlet portion, and the connection portion; and a flow guide portion guiding the water flowing into the inlet portion to flow into the water treatment unit, and guiding the water treated by the treatment unit to flow into the outlet portion.

3 . The water treatment apparatus of claim 2 , wherein the flow guide portion includes:
a passage forming member including an inflow passage having an open lower portion connected to an inflow portion included in the water treatment unit and connected to the inlet portion, and an outflow passage connected to the outlet portion and the connection portion; and an opening/closing member rotatably provided on the passage forming member and including a plurality of opening/closing apertures formed therein to open or close a plurality of first inflow apertures or a plurality of second inflow apertures formed in the inflow portion according to a rotating location of the opening/closing member.

4 . The water treatment apparatus of claim 3 , wherein the plurality of first inflow apertures and the plurality of second inflow apertures are spaced apart from each other by a predetermined interval, are formed in a circumference of a virtual circle on the inflow portion, and have diameters of which the sizes are decreased in a single direction; and
the plurality of opening/closing apertures have slots with different lengths, are spaced apart from each other by a predetermined interval and are formed in the opening/closing member in locations corresponding to locations of the plurality of first inflow apertures and the plurality of second inflow apertures.

5 . The water treatment apparatus of claim 3 wherein the flow guide portion further comprises:
a connection member connected to the opening/closing member to block an open upper portion of the passage forming member; and
a gripping member connected to the connection member.

6 . The water treatment apparatus of claim 5 , wherein the opening/closing member and the connection member have an elastic member provided therebetween.

7 . The water treatment apparatus of claim 1 , wherein the connection portion is connected to an auxiliary connection member supporting the connection of the water treatment unit to the connection portion, and
the auxiliary connection member includes a locking release member locking or unlocking the connection of the water treatment unit.

8 . The water treatment apparatus of claim 6 , wherein the auxiliary connection member is connected to a bracket.

9 . The water treatment apparatus of claim 1 , wherein the water treatment unit includes:
an inlet/outlet member having an inflow portion into which water flows from the head and an outflow portion through which water is discharged to the head; and a housing connected to the inlet/outlet member, including a first water treatment section and a second water treatment section, and configured such that a portion of the water flowing into the inflow portion passes through the first and second water treatment sections sequentially, the remainder of the water passes through only the second water treatment section, and the water flows together to the outflow portion.

10 . The water treatment apparatus of claim 9 , wherein the second water treatment section is located above the first water treatment section; and a portion of the water flowing into the inflow portion flows into a lower portion of the housing and then passes through the first and second water treatment sections sequentially, and the remainder of the water passes through only the second water treatment section.

11 . The water treatment apparatus of claim 10 , wherein the first water treatment section includes a functional substance or an ion-exchange resin, and the second water treatment section includes carbon particles.

12 . The water treatment apparatus of claim 10 , wherein the inflow portion includes a plurality of first inflow apertures and a plurality of second inflow apertures, and the outflow portion includes a plurality of outflow apertures.

13 . The water treatment apparatus of claim 12 , wherein the housing further comprises:
a first guide member including a first passage connected to the plurality of first inflow apertures so that water passing through the plurality of first inflow apertures flows into the first passage; a second guide member including a second passage connected to the first passage so that water passing through the first passage flows into a lower portion; and a third guide member into which the second guide member is inserted so that a bypass passage is formed therebetween, the bypass passage being connected to the second water treatment section and the plurality of second inflow apertures so that water passing through the plurality of the second inflow apertures flows into the second water treatment section.

14 . The water treatment apparatus of claim 13 , wherein the housing further comprises a fourth guide member including a third passage connected to the second passage so that water passing through the second passage flows into the lower portion.

15 . The water treatment apparatus of claim 9 , wherein the housing includes one or more partitioning members formed of a water permeable material partitioning the first and second water treatment sections.

16 . The water treatment apparatus of claim 15 , wherein the partitioning members are formed of non-woven fabric.
