The inner front filter 72 may include an inner front frame 720 and a plurality of meshes M, and the inner rear filter 73 may include an inner rear frame 730 and a plurality of meshes M. That is, the inner filter cartridge 71 is composed of an inner filter frame 710 and a plurality of meshes M, and the inner filter frame 710 is again composed of an inner front frame 720 and an inner rear frame 730 will be. This is shown in FIG. 8 .

Openings P1 and P2 in which a front mesh is installed may be formed in the inner front frame 720 , and openings P3 and P4 in which a rear mesh is installed may be formed in the inner rear frame 730 . In this case, a part of the inner front frame 720 in which the openings P1 and P2 are formed is called an inner front part 721 , and a part of the inner rear frame 730 in which the openings P3 and P4 are formed is part of the inner rear part. (731). In addition, portions extending toward the inner rear portion 731 from both sides of the inner front portion 721 become inner side portions 712 and 713 .

The inner front filter 72 and the inner rear filter 73 may be detachably coupled to each other. This coupling can be made using only the elasticity of the material without a separate fastening member. To this end, a hook 736 is formed in at least one of the inner front frame 720 and the inner rear frame 730 , and a coupling portion having an appropriate shape to be coupled to the hook 736 may be formed in the other.

Since the opening tab 781 is coupled to the fixing holder 758 , the opening of the side frame 780 may be interrupted.

Meanwhile, a side stopper protrusion 767 may be provided on the outer rear frame 760 to prevent the side frame 780 from being deployed at a predetermined angle or more. In a state in which the side frame 780 is deployed, the side stopper protrusion 767 contacts the outer rear frame 760 , thereby limiting the deployment range of the side frame 780 .

On the other hand, a number of protruding components exist outside the outer filter cartridge 74 . For example, the spacer protrusions 753 , 763 , the stopper protrusions 755 , 765 , 767 , and the open tab 781 may protrude from the outer filter frame 740 to the outside. Therefore, in the process of withdrawing the outer filter cartridge 74 from the discharge duct 53 , interference may occur between the protruding components and the sealing member 9 . Accordingly, it is possible to prevent the filter cartridge 7 from interfering with the sealing member 9 by additionally forming a guide rib on each of the protruding components. Hereinafter, the guide rib will be described in more detail with reference to FIGS. 11 to 15 .

11 and 12 are enlarged views illustrating parts A and B of FIG. 9 , respectively. 13 and 14 are enlarged views illustrating portions C and D of FIG. 10 , respectively. 15 is a view illustrating a side frame of FIG. 9 .

First, referring to FIG. 11 , a first guide rib 754 extending vertically may be provided on the first spacing protrusion 753 . That is, the first guide rib 754 may extend up and down by a predetermined distance along the drawing-out direction of the outer filter cartridge 74 around the first spacing protrusion 753 .

Since the first spacer protrusion 753 is provided at the lower left and lower right sides of the outer front frame 740 , the first guide rib 754 may also be provided on each of the pair of first spacer protrusions 753 .

Meanwhile, the height at which the first guide rib 754 protrudes may be substantially the same as that of the first spacer protrusion 753 . In addition, the first guide rib 754 extends upward from the first spacer protrusion 753 but extends downward from the first inclined portion 7541 whose protruding height is gradually lowered, and the first spaced protrusion 753 . However, it may include a second inclined portion 7543 whose protruding height is gradually lowered. Accordingly, even if the first guide rib 754 comes into contact with the sealing member 9 in the process of taking out the outer filter cartridge 74 , the sealing member 9 may not be removed from the input surface 52 .

In addition, as shown in Figure 9 (b), the lower left and right lower ends of the outer rear frame 750 is provided with a second spacer protrusion 763, respectively, the second spacer protrusion 763 also the first guide rib Second guide ribs 764 substantially identical to 754 may each be provided.

12 and 13 , a third guide rib 756 and a fourth guide rib 766 extending vertically may be provided on the front stopper protrusion 755 and the rear stopper protrusion 765 , respectively.

The third guide rib 756 extends upward along the front reinforcing frame 751 from the front stopper protrusion 755 , and the fourth guide rib 766 supports the rear reinforcing frame 761 from the rear stopper protrusion 765 . It can be extended upward accordingly.

On the other hand, in FIG. 9(a), the third guide rib 756 extends from the front stopper protrusion 755 to the opposite side of the outer front frame 750 to cover all of the front reinforcement frame 751, and FIG. 9(b) shows that the fourth guide rib 766 extends from the rear stopper protrusion 765 to cover only a portion of the rear reinforcement frame 761 . However, the present invention is not limited thereto, and the extension lengths of the guide ribs 756 and 766 may be variously changed as needed.

That is, the fourth guide rib 766 may also extend to cover the entire rear reinforcing frame 761 like the third guide rib 756 , and on the contrary, the third guide rib 756 is also the fourth guide rib 766 . As such, it may be extended to cover only a portion of the front reinforcement frame 751 . However, when the guide rib covers only a part of the reinforcing frame, it is preferable to form the guide rib so that the protruding height gradually decreases toward the upper portion. This is to prevent the guide rib from interfering with the sealing member 9 in the process of withdrawing the outer filter cartridge 74 .

In addition, although it is illustrated that a third guide rib 756 and a fourth guide rib 766 are provided in pairs in FIGS. 12 and 13 , the present invention is not limited in this way. That is, the provision of the pair of third guide ribs 756 is a result of the shape of the front stopper protrusion 755 , and the fourth guide rib 766 is also the same. Accordingly, the number of the third and fourth guide ribs 756 and 766 may vary depending on the shape of the stopper protrusions 755 and 765 .

Referring to FIG. 14 , a fifth guide rib 768 extending vertically may be provided on the side stopper protrusion 767 . That is, the fifth guide rib 768 may extend up and down by a predetermined distance along the drawing-out direction of the outer filter cartridge 74 around the side stopper protrusion 767 .

The fifth guide rib 768 extends upward from the side stopper protrusion 767, but extends downward from the third inclined portion 7681 whose protruding height is gradually lowered, and the side stopper protrusion 767, but the protruding portion A fourth inclined portion 7683 whose height is gradually lowered may be included. Accordingly, even if the fifth guide rib 768 comes into contact with the sealing member 9 in the process of taking out the outer filter cartridge 74 , the sealing member 9 may not be removed from the input surface 52 .

Referring to FIG. 15 , a plurality of rails 783 may be provided on the side frame 780 . For example, the rail 783 includes a pair of vertical rails 7831 and 7832 extending up and down along the drawing out direction of the outer filter cartridge 74 and a horizontal rail connecting the vertical rails 7831 and 7832 . (7833). Alternatively, more or fewer rails may be provided according to the shape of the side frame 780 .

The height at which the rail 783 protrudes from the side frame 780 may be the same as the height at which the open tab 781 protrudes. Therefore, when the sealing member 9 comes into contact with the opening tab 781 when the outer filter cartridge 74 is drawn out, the rail 783 also comes into contact with the sealing member 9, so that the sealing member 9 closes the open tab 781 ) to prevent it from being caught and removed.

The vertical rails 7831 and 7832 may be formed such that the protruding heights of both ends are gradually lowered. That is, the protruding height of the upper ends of the vertical rails 7831 and 7832 may gradually decrease toward the upper end, and the protruding height of the lower end of the vertical rails 7831 and 7832 may gradually decrease toward the lower end. Through this, even when the vertical rails 7831 and 7832 come into contact with the sealing member 9 in the process of withdrawing the outer filter cartridge 74 , the sealing member 9 may not be removed from the input surface 52 .

The horizontal rail 7833 may have a shape in which the height protruding along the withdrawal direction of the outer filter cartridge 74 gradually increases and then decreases again. For example, the cross-sectional shape of the horizontal rail 7833 may be semicircular, elliptical, triangular, or the like. This is to prevent the sealing member 9 from being caught by the horizontal rail 7833 when the outer filter cartridge 74 is drawn out.

As described above, on the outer surface of the outer filter cartridge 74, there are a number of protruding components such as spacer protrusions 753 and 763, stopper protrusions 755, 765, 767, and an open tab 781. The protruding components may interfere with the sealing member 9 when the outer filter cartridge 74 is drawn out. In the present invention, guide ribs 754 , 764 , 756 , 766 , 768 are formed on each of the protruding components, or a rail structure 783 is formed on the side frame 780 . Accordingly, when the outer filter cartridge 74 is drawn out, interference between the protruding components and the sealing member 9 can be suppressed, and the problem of the sealing member 9 being removed can be solved.
