In this embodiment, when the second part 224 comes into contact with the first wall 192, the movement of the second valve device 212 is restricted, so that the position of the third valve 213 is fixed and stable. can be maintained as Therefore, vibration of the third valve 213 may be minimized during operation of the third valve 213 .

In this embodiment, the third part 226 may be referred to as a fixing part, and the second part 224 may be referred to as a contacting part.

15 is a view showing a state in which filters are rotated in the filter module according to the present embodiment.

Referring to FIGS. 3 and 15 , in order to replace the filter 120 , the refrigerating compartment door 22 may be opened first. Then, the drawer 50 can be separated from the cabinet 10 by pulling the drawer 50 . Then, the filter 120 may be exposed to the outside. The user may hold the filter 120 and rotate the filter 120 so that the lower side of the filter 120 rotates forward.

Then, the filter 120 may protrude forward of the mounting plate 101 through the filter opening 101a of the mounting plate 101 . In this state, the user can separate the filter 120 from the head 110 .

Contrary to what has been described above, after the filter 120 to be newly mounted is coupled to the head 110, the filter 120 can be rotated so that the filter 120 is accommodated in the filter accommodating space 106. Then, the drawer 50 may be accommodated in the refrigerating compartment 12 .

According to the proposed embodiment, since the filter is exposed to the outside when the drawer is taken out of the cabinet, a refrigerator in which the user can easily recognize the filter and replace the filter is provided.

In the case of this embodiment, since the filter, water tank, and valve device are installed on the mounting plate, the user can easily install the filter, water tank, valve device, etc. on the mounting plate, and fix the mounting plate to the inner case, so that the filter module It has the advantage of being easy to assemble and install.
