a flow channel that provides a passage through which raw water or purified water flows; a valve unit including at least one valve module that is selectively opened and closed to control the flow of raw water or purified water in the flow channel; a cock for discharging the purified water to the outside; a housing including a first housing in which the filter unit, flow channel, and valve unit are arranged, and a second housing disposed on the front side of the first housing; and a cock support member that is detachably engaged with the cock and the housing. ## Claims ### Claim 1 A water purifier comprising: a filter unit that filters raw water to provide purified water; a flow channel that provides a passage through which the raw water or the purified water flows; a valve unit including at least one valve module that is selectively opened and closed to control a flow of the raw water or the purified water in the flow channel; a cock for discharging the purified water to an outside of the water purifier; a housing including a first housing in which the filter unit, the flow channel, and the valve unit are accommodated, and a second housing disposed on a front side of the first housing; and a cock support member that is detachably engaged with the cock and the housing. ### Claim 2 (depends on 1) The water purifier of claim 1, wherein the cock support member includes: a cock support body; and a cock support engagement part supported by the cock support body and having a housing engagement part that is formed to engage with the second housing, wherein the cock support body closely contacts the second housing when the second housing engages with the housing engagement part. ### Claim 3 (depends on 2) The water purifier of claim 2, wherein the cock support engagement part has a cock contact part that closely contacts an end of the cock when the cock support engagement part is connected to the cock, and wherein the cock contact part includes: a first contact surface facing a lower surface of the cock; and a second contact surface extending in a circumferential direction to surround a lower end of the cock. ### Claim 4 (depends on 3) The water purifier of claim 3, further comprising an O-ring disposed between the lower end of the cock and the second contact surface to seal a gap between the cock and the cock support member. ### Claim 5 (depends on 2) The water purifier of claim 2, wherein the cock support body extends horizontally from the cock support engagement part, wherein the upper surface of the cock support body and the lower surface of the second housing closely contact each other, wherein the cock support engagement part closely contacts the cock, and wherein a contact area between the upper surface of the cock support body and the lower surface of the second housing is greater than a contact area between the cock support engagement part and the cock. ### Claim 6 (depends on 2) The water purifier of claim 2, wherein the cock includes: a cock body; and a stopper protruding from the cock body to prevent the cock support member from rotating beyond a predetermined rotational phase angle or rising beyond a predetermined distance. ### Claim 7 (depends on 6) The water purifier of claim 6, wherein the cock includes a protrusion extending laterally from the cock body and comprising a protruding engagement part formed to engage with the cock support member. ### Claim 8 (depends on 2) The water purifier of claim 2, wherein the cock support member is configured to engage with the cock and the housing by being rotated. ### Claim 9 (depends on 8) The water purifier of claim 8, wherein the cock support member, in a detached state from the cock and the housing, approaches the cock in a first position to closely contact at least one of the housing and the cock, and is rotated by a predetermined rotational phase angle from the first position to a second position to engage with the housing and the cock. ### Claim 10 (depends on 9) The water purifier of claim 9, wherein a housing recess is formed in the second housing, and when the housing engagement part is disposed above the housing recess in the first position, the cock support member is allowed to be detached from the housing. ### Claim 11 (depends on 10) The water purifier of claim 10, wherein the second housing has a hole portion through which the cock support member penetrates and the housing recess is formed, and wherein in a state where the cock support member is coupled to the housing, a shortest distance from one end of the cock support body to the cock support engagement part is greater than the horizontal gap size between the housing and the cock support member in the hole portion. ### Claim 12 (depends on 10) The water purifier of claim 10, wherein the cock includes: a cock body; and a protrusion protruding laterally from the cock body and comprising a protruding engagement part formed to engage with the cock support member, wherein a cock engagement part is formed in the cock support engagement part, and wherein the cock support member is allowed to be detached from the cock when the protrusion is disposed at the cock engagement part in the first position. ### Claim 13 (depends on 12) The water purifier of claim 12, wherein an engagement slit is formed in the cock support engagement part, wherein the engagement slit engages with the protruding engagement part when the cock support member is rotated to the second position relative to the cock to engage with the cock, and wherein movement of the cock is restricted when the protruding engagement part is engaged in the engagement slit. ### Claim 14 (depends on 1) The water purifier of claim 1, wherein the cock is integrally formed with the flow channel or is separately formed to be detachable from the flow channel.
