6 is a view showing the inside of a water filter assembly in which a protective cover and a drain part are formed according to an embodiment of the present invention, FIG. 7 is a partially enlarged view of FIG. 6, and FIG. 8 is a drain part according to an embodiment of the present invention. It is a partial cross-sectional view of the water filter assembly showing drainage through, and FIG. 9 is a schematic perspective view of the drain part according to an embodiment of the present invention.

Referring to these drawings, the water filter assembly 10 according to the present invention includes a filter body 500 in which raw water flowing in from the outside is purified, and a storage tank connected to one side of the filter body 500 and storing the purified raw water. 300 , a second case 12 in which the filter body 500 is stored, and a first case 11 in which the storage tank 300 is stored may be configured. Here, in the second case 12 , a drain unit 700 in which water dripping from the filter body 500 collects may be formed. The drain part 700 may be mounted to be taken out from the second case 12 .

The filter body 500 may be stored in the second case 12 . The second case 12 is formed in a substantially rectangular shape, and may include a cover 15 that is detachably attached to open and close one side. Here, a protective cover 12 - 3 into which a portion of the filter body 500 can be inserted may be coupled to the ends of the second case 12 and the cover 15 . The protective cover 12-3 may be formed in a shape extending from the ends of the second case 12 and the cover 15 to one side to facilitate replacement by withdrawing the filter body 500 . In some cases, it may be formed to be detachable, for example, the protective cover 12-3 is not particularly limited as long as it has a structure that is detachable from the ends of the second case 12 and the cover 15, For example, it may be a pressurized hook fastening method or a screw fastening method using bolts or the like.

Since the protective cover 12-3 is formed in a shape extending from one end in a state in which the second case 12 and the cover 15 are coupled, one end on the filter body 500 is the protective cover 12-3. ) can be easily inserted. That is, one end of the filter body 500 may be inserted into the protective cover 12-3 in a form exposed to the outside of the second case 12 and the cover 15 . Accordingly, after the user removes the protective cover 12 - 3 from the second case 12 and the cover 15 , the filter body 500 can be easily replaced and repaired. As such, a method of taking out the filter body 500 from the protective cover 12-3 will be described in more detail below with reference to the drawings.

Meanwhile, in the second case 12 and the cover 15 , in a state in which they are coupled to each other, a draw-out hole 12-2 may be formed so that the drain unit 700 can be drawn in and out. Since the drain unit 700 is disposed under the filter body 500 disposed on the second case 12 and the cover 15 , it is possible to induce water dripping from the filter body 500 to accumulate. .

The drain unit 700 includes an inclined surface 720 and an inclined surface 720 formed to be inclined at a predetermined angle in the longitudinal direction so as to be movable in one direction after the water or water falling from the filter body 500 is dripped. It may be configured to include a take-out portion 710 that extends from one side and can be drawn in or withdrawn from the second case 12 in a state held by the user. At this time, the drain unit 700 is not particularly limited as long as it has a structure that allows the falling water, etc. to flow in one direction, and a structure in which an inclined surface 720 whose height is reduced in one direction is formed as described above. Or, it may have a structure in which it is inclinedly inserted when mounted on the second case 12 without a separate inclined surface due to a different height. Preferably, the drain unit 700 may be a plastic molded product made of a transparent or translucent material in consideration of visibility and usability, but is not limited thereto.

Therefore, by forming the drain part 700 with a transparent or translucent material, visibility from the outside is secured and internal leakage can be checked, and the internal filter can be directly checked and replaced or repaired through the transparent front part. have. For example, since it is possible to visually check the inside through the train unit 700 directly, it is possible to check in advance and prevent a phenomenon in which the filter is frozen due to a system error such as internal overcooling.

Here, the drain part 700 is disposed on the lower part of the filter body 500 , and when the filter body 500 is detached for replacement, the remaining water of the filter body 500 is completely dripped and collected by the drain part 700 . To this end, the length W ₁ of the drain part 700 may be located between the coupling portion of the filter body 500 and the head part 200 . This is because moisture, etc. may also be generated in the portion where raw water flowing from the inlet port 210 and the outlet port 220 of the head unit 200 flows into the filter body 500, so it is preferable to have a length extending to such a portion. may be desirable. That is, of course, the length W ₁ of the drain part 700 may be formed in a shape extending to one end W ₂ of the head part 200 (refer to the red dotted line). Therefore, in the process of attaching and detaching the filter body 500 and the head part 200, the fluid can be easily taken out even when the fluid flows backward between the length W ₁ and the length W ₂ at the coupling site.

10 is a perspective view of a filter body according to an embodiment of the present invention, and FIG. 11 is a view showing a state of use of a drain unit according to an embodiment of the present invention.

A method of withdrawing the filter body 500 and the drain unit 700 will be described with reference to these drawings. As described above, the filter body 500 and the drain unit 700 of the present invention are detachably attached to the second case 12 . It may be a structure in which this is possible. Here, the filter body 500 is to be configured to include a filter body casing 510, an upper casing 520 rotatably coupled to the head 200, and a lower casing 530 in which the user's hand 531 is formed. can

Under the structure as described above, the user removes the hand part 531 formed in the lower casing 530 exposed to the outside of the protective cover 12-3 in the state where the filter body 500 is mounted on the second case 12 . By rotating, the filter body 500 can be easily detached from the second case 12 . Furthermore, since a gripping groove (not shown) is formed in the outlet portion 710 of the drain unit 700 , the user may in some cases have the gripping groove having a recessed shape formed in the outlet portion 710 of the drain portion 700 . It is possible to remove the water collected inside by holding it and withdrawing it to the outside.

12 is a partial cross-sectional view of a filter body according to an embodiment of the present invention.

Referring to FIG. 12 , the head part 200 is provided on the upper side of the filter case 100 . The head part 200 may be formed to protrude upward from the upper side of the filter case 100 .

An inlet port 210 and an outlet port 220 may be formed in the head part 200 . The inlet port 210 and the outlet port 220 may be formed to protrude from the circumference of the head part 200 in a radial direction. The inlet port 210 and the outlet port 220 may be formed to protrude in opposite directions to each other. The inlet port 210 may be formed to protrude in a radial direction from one side of the circumference of the head unit 200 , and the outlet port 220 may be formed to project in a radial direction from the other side of the circumference of the head unit 200 .

The inlet port 210 and the outlet port 220 may be formed in a tubular shape. Raw water may be introduced into the inlet port 210 . In the outlet port 220 , purified water from the filter body 1 may flow out. Raw water introduced into the filter case 100 through the inlet port 210 may be purified in the filter case 100 and then discharged to the outside of the filter body 1 through the outlet port 220 .
