[0150] Referring to FIG. 9, water flowing into the filter case (110) can flow into the sealing groove (135) of the sealing member (130) through the gap (G) between the filter case (110) and the filter cover (126). A portion of the sealing member (130) can be deformed by the water pressure of the water flowing into the sealing groove (135). The water flowing into the sealing groove (135) can press the sealing member (130) toward the case body (111) and the filter cover (126). The water flowing into the sealing groove (135) can press the sealing rib (133) against the case body (111). The water flowing into the sealing groove (135) can press the extension (134) against the filter cover (126).

[0151] According to one embodiment of the present disclosure, the filter module (100) may be provided so that, when the filter (120) is mounted on the filter case (110), the sealing rib (133) and the extension (134) of the sealing member (130) are more closely attached to the filter case (110) and the filter (120) by water pressure when water flows into the interior of the filter case (110) than when water does not flow into the interior of the filter case (110). According to one embodiment of the present disclosure, the filter module (100) may be provided so that, when water pressure does not flow into the interior of the filter case (110), the sealing rib (133) and the extension (134) are less closely attached to the filter case (110) and the filter (120) than when water pressure is generated inside the filter case (110).

[0152] Accordingly, the filter module (100) according to one embodiment of the present disclosure can relatively reduce the frictional force between the sealing member (130) and the filter case (110) while mounting the filter (120) in the filter case (110), thereby reducing the force required to mount the filter (120).

[0153] In addition, since the filter module (100) according to one embodiment of the present disclosure can relatively reduce the frictional force between the sealing member (130) and the filter case (110) while mounting the filter (120) to the filter case (110), the force required to mount the filter (120) to the filter case (110) can be reduced even if there is no lubricant between the sealing member (130) and the filter case (110). Since the filter module (100) according to one embodiment of the present disclosure can omit the lubricant for the sealing member (130), the cost can be reduced.

[0154] In addition, since the filter module (100) according to one embodiment of the present disclosure is provided so that the sealing member (130) is brought into close contact with the filter case (110) and the filter (120) by using the water pressure inside the filter case (110), there is no need to bring the sealing member (130) into close contact with the filter case (110) when mounting the filter (120) on the filter case (110), and therefore, there is no need to rotate the filter (120) several times when mounting the filter (120) on the filter case (110). The filter module (110) according to one embodiment of the present disclosure can mount the filter (120) on the filter case (110) by rotating the filter (120) by a relatively small angle. For example, referring to FIGS. 4 and 10, the filter module (100) can be provided so that the filter (120) can be mounted on the filter case (110) by rotating it by approximately 60 degrees.

[0155] A filter module (100) according to one embodiment of the present disclosure can improve the sealing performance of a sealing member (130) by utilizing the water pressure of water flowing into the filter module (100).
