The lower edge of the first filtration filter 42 may be disposed on the edge of the flange 431.

That is, when the size of the opening surface of the lower edge of the first filtration filter 42 and the area of the flange 431 coincide, when the inner assembly 100 and the protrusion 121 are combined, the protrusion 121 is not visually covered. Can be combined.

When the size of the flange 431 was too large, the protrusions 121 of the water tank were visually obscured by the flanges 431, making it difficult to join the protrusions 121 by matching the recesses 44b.

In addition, the huge flange 431 may be more likely to be damaged.

The lower filter cover 43 may include an elastic body.

In the present specification, the elastic body is not limited to a material having elastic properties above a standard, and should be understood as a concept opposite to a rigid body having no restoration of deformation. For example, the elastic body may include a polymer (plastic, rubber) or the like.

However, the constituent material of the lower filter cover 43 is not limited to the above description, and it will be included to the extent that a person skilled in the art can easily apply.

For example, the lower filter cover 43 may include a rigid metal or the like.

The upper edges of the second filtration filter 44 and the first filtration filter 42 may be connected by a plate-shaped upper filter cover 46.

Specifically, the upper edge of the second filtration filter 44 and the upper edge of the first filtration filter 44 may be structurally supported by being connected to the upper filter cover 46 extending in the horizontal direction.

The upper filter cover 46 is combined with the drip tray 50 to form a single inner assembly 100 together with the water supply plate 30 and the like.

The upper filter cover 46, the first filtration filter 42, and the second filtration filter 44 may be combined by a known coupling method or may be an integral structure.

The second filtration filter 44 and the concave portion 44b and the first filtration filter 42 are spaced apart from each other, but are connected to each other by the upper filter cover 46 on the upper side and the lower filter cover 43 on the lower side to be stable. Can be supported.

Above, although the embodiments of the present invention have been illustrated and described, the present invention is not limited to the specific embodiments described above, and is common in the technical field to which the present invention pertains without departing from the gist of the present invention as claimed in the claims. Of course, various modifications can be made by a person skilled in the art, and these modifications should not be individually understood from the technical idea or prospect of the present invention.
