The arrangement of adjacent pieces along the screen frame P1 is as follows. According to one embodiment, as shown in Figs. 1 and 2, the pieces may be arranged such that adjacent portions do not overlap.

FIG. 3 is a view for explaining a method of arranging the main body according to the present invention, that is, a method for arranging adjacent pieces according to an embodiment different from FIGS. 1 and 2. FIG. The body portion 23 of FIG. 3 differs from the body portion 23 of FIGS. 1 and 2 only in the manner of placing adjacent pieces. Therefore, in the following, referring to FIG. 3, a method of arranging adjacent pieces will be described with reference to the differences from FIGS. 1 and 2. FIG.

Referring to FIG. 3, the main body 23 is composed of a plurality of pieces 23A1 ', 23B1', 23C1 'and 23D1'. The pieces 23A1 'and 23B1', the pieces 23B1 'and 23C1', the pieces 23C1 'and 23D1', and the pieces 23A1 'and 23C1' Piece 23D1 'and the piece 23A1'. However, the main body 23 of FIG. 3 may be arranged such that at least a part of a neighboring portion of the body 23 is overlapped with a plurality of pieces 23A1 ', 23B1', 23C1 ', and 23D1'.

3, the piece 23A1 'and the piece 23B1', the piece 23B1 'and the piece 23C1', the piece 23C1 'and the piece 23D1', the piece 23D1 ' The piece 23A1 'is arranged such that a part of the adjacent portion overlaps. The overlapped portion can be made in an approximately oval shape for safety during assembly. In the superimposing method, the pieces 23A1 'and 23B1' are taken as an example. After the pieces 23A1 'are arranged, the pieces 23B1' are arranged at the portions where the pieces 23A1 'and 23B1' Are arranged so as to overlap each other on the upper side of the piece 23A1 '. At this time, the portion where the piece 23A1 'and the piece 23B1' are overlapped can be bonded by spot welding (spot welding).

The filter coupling part 21 is coupled to the main body part 23 after the main body part 23 is coupled to the screen guard frame P1 or P2 in the same manner as in the first to third embodiments. The manner of coupling the main body 23 with the screen molds P1, 92 will be described later with reference to FIG. 3 to FIG.

The filter coupling portions 21 are respectively coupled to the main body portions 23 respectively coupled to the four sides of the screen frame P1. Two pairs of filter coupling parts 21A1, 21B1, 21C1 and 21D1 are coupled to the four main parts 23A1, 23B1, 23C1 and 23D1, respectively. When the respective filter engaging portions 21A1, 21B1, 21C1 and 21D1 are engaged with the respective body portions 23A1, 23B1, 23C1 and 23D1, the position in the direction perpendicular to the body portions 23A1, 23B1, 23C1 and 23D1 And may be movably coupled. The manner of engagement between the filter coupling portion 21 and the main body portion 23 and the coupling position will be described later with reference to FIGS. 3 to 7

For example, the filter coupling portion 21A1 coupled to the main body portion 23A1 coupled to the X-axis direction of the screening panel P1 shown in FIG. 1 is coupled to the main body portion 23A1 so as to be positionally movable in the Y- . The filter coupling part 21B1 coupled to the main body part 23B1 coupled to the Y-axis direction of the screen mold frame P1 can be movably moved in the X-axis direction perpendicular to the main body part 23B1.

The filter coupling portion 21X2 coupled to the body portion 23A2 coupled to the X-axis direction of the screen panel P2 can be moved in the Y-axis direction perpendicular to the body portion 23A2. The filter coupling part 21Y2 coupled to the main body part 23B2 coupled to the Y axis direction of the screen panel P2 can be movably moved in the X axis direction perpendicular to the main body part 23B2.

That is, the position of the filter coupling part 21 can be moved to the main body part 23 in accordance with the size of the screening frame P1 of FIG. 1 and the screening frame P2 of FIG. Therefore, it is possible to combine the ultrafine dust filter with the window frame or window frame having different sizes for each building.

The filter is detachably coupled to the coupling assembly (10). According to one embodiment of the present invention, the filter 10 may be detachably coupled to the filter coupling 21 after the coupling assembly 20 is coupled to the screen framework P1 or P2. That is, since the filter 10 is not directly coupled to the insect screen frame P1 or P2, it is possible to easily replace the filter 10 without removing the screen frame P1 or P2. Once the coupling assembly 20 is assembled to match the size of the insect screen frame P1 and P2, only the filter 10 coupled to the filter coupling 21 is removed and replaced when the filter 10 needs to be replaced Therefore, it is very easy to cut out the pieces to fit the sizes of the screen molds P1 and P2 each time it is replaced. A method of coupling the filter 10 and the coupling assembly 20 will be described later with reference to FIGS. 4 to 9. FIG.

Now, a method of coupling the coupling assembly 20 will be described in detail with reference to FIGS. 4 to 9. FIG. The coupling method of the coupling assembly 20 is similar to the coupling method of the main body part 23 and the screen guard frame P1 or P2, the coupling method of the filter coupling part 21 and the main body part 23, 10 and the filter coupling portion 21, respectively.

FIG. 4 is an enlarged cross-sectional exploded view taken along the line A1-A1 'shown in FIG. 1 to illustrate a coupling method of the coupling assembly 20 according to an embodiment of the present invention. Sectional view taken along the line A1-A1 'shown in FIG. 1 and the cross-sectional view taken along the line A2-A2' shown in FIG. According to one embodiment of the present invention, since the screen frame P1 of FIG. 1 is wider and longer than the screen frame P2 of FIG. 2, only the position where the combining assembly 20 is engaged is different The method is the same.

Therefore, the coupling method of the coupling assembly 20 will be described with reference to FIG.

Referring to FIG. 4, the coupling assembly 20 according to one embodiment includes a body portion 23 coupled to the screen frame P1 and a body portion 23 that can be positionally movably coupled in a direction perpendicular to the body portion 23 And a filter coupling portion 21.

The body portion 23 may be made of a rust-resistant metal material. For example, it can be made of a material that is not corroded and has good durability, such as aluminum and stainless steel. However, this is merely an example, and may be made of a non-metallic material such as synthetic resin (PVC).

An exemplary method of combining the main body 23 with the screen frame P1 according to this configuration is as follows. The main body portion 23 is fixedly coupled to the screen frame P1 by an adhesive, an adhesive tape or the like. However, this is merely an example and any material can be used as long as it can fix the main body portion 23 and the screen frame P1 in a fixed manner.

Although not shown, a hole may be formed in the main body portion 23 so as to more firmly connect the main body portion 23 to the screen frame P1, and screwing through the hole may be possible.

The main body portion 23 includes first main body portions 23a and 23b that are in contact with the screen guard frame P1 when coupled to the screen guard frame P1 and second main frame portions 23c that are not in contact with the screen frame P1, . ≪ / RTI > That is, the main body 23 can be coupled to the screen frame P1 so that only the first main body 23a or 23b contacts the screen frame P1.

The first body portions 23a and 23b may be formed in the same shape as the outer peripheral portion of the screen frame P1 so that the first body portions 23a and 23b can be contacted while wrapping the screen frame P1. As shown in the figure, when the screen frame P1 has a rectangular shape, the first body portions 23a and 23b may be formed to include a rectangular shape so as to be contacted while covering the screen frame P1. 4 to 9, the shape of the insect screen frame P1 and P2 is a rectangular shape, and the first body portions 23a and 23b contacting the first and second inspecting frame shapes P1 and P2 include a rectangular shape. However, if this is an example and the curved surface is included in the shape of the screen mold P1, the first main body portions 23a and 23b may be formed to include curved surfaces of the same shape.

The second body portion 23c is a portion that does not contact the screen frame P1 and the filter coupling portion 21 is engaged with the second body portion 23c. The filter coupling portion 21 may be movably coupled in a direction perpendicular to the second body portion 23c. The filter coupling portion 21 may be moved to fit the length of the screen frame P1 and then coupled to the second body portion 23c.

1, the filter coupling portions 21A1 and 21C1 coupled to the body portions 23A1 and 23C1 coupled to the X-axis direction of the screen frame P1 are connected to the Y- As shown in Fig. The filter engaging portions 21B1 and 21D1 coupled to the body portions 23B1 and 23D1 coupled to the Y axis direction of the screen frame P1 are movable in the X axis direction perpendicular to the body portions 23B1 and 23D1 Lt; / RTI > That is, after the filter coupling portions 21A1, 21C1, 23B1 and 23D1 are moved to fit the width X1 and length Y1 of the screen frame P1, the filter coupling portions 21A1, 21C1, 23B1 and 23D1 are coupled to the body portions 23A1, 23C1, 23B1 and 23D1 . At this time, the body portions 23A1, 23C1, 23B1, and 23D1 will correspond to the second body portion 23c of FIG.

According to one embodiment of the present invention, the width X1 and length Y2 of the screen frame P1 of FIG. 1 are wider than the width X2 and length Y2 of the screen frame P2 of FIG. 2 So that the screen frame P1 is larger than the screen frame P2. Assuming that the distance at which the filter coupling portion 21 is movable in the direction perpendicular to the second main body portion 23c is 'L', the filter coupling portion 21 of FIG. 1 has '2L', Y It is possible to move the position by '2L' in the axial direction. This is because the pair of filter coupling parts 21A1 and 21C1 are coupled to the X axis of the screen frame P1 and the other pair of filter coupling parts 21B1 and 21D1 are coupled to the Y axis.

That is, the insect screen frame P1 may be an insect screen frame (X1 = X2 + 2L, Y1 = Y2 + 2L) which is larger by 2L in the maximum X axis direction and 2L in the Y axis direction than the screen frame P2, The filter coupling unit 21 can be moved and adjusted to fit the size of the screen guard frame.

5, since the insect screen frame P1 is longer than the insect screen frame P2 by 'L' in the Y axis direction, the insect screen frame P1 is positioned lower by 'L' than the filter connecting portion 21 of the insect screen frame P2 And is moved and coupled. As described above, since the coupling assembly 20 according to the present invention can move the position of the filter coupling part 21 coupled to the main body part 23 even if the size of the screening frame is different, the filter 10 of the same size can be used So that the filter 10 and the coupling assembly 20 can be standardized.

Referring again to FIG. 4, a coupling method of the filter 10 and the filter coupling unit 21 will be described.

Referring to the drawings, the filter 10 and the filter coupling unit 21 according to an embodiment include a first opposing face 10a and a second opposing face 10b which are opposed to each other when the filter 10 is coupled to the filter coupling unit 21, And two opposing surfaces 21a, respectively. The first attachment member 15 and the second attachment member 25 that can be mutually attached to each other by a magnetic force may be provided on the first opposing face 10a and the second opposing face 21a, respectively.

At least one of the first attachment member 15 and the second attachment member 25 may be made of a magnet. For example, the first attachment member 15 provided on the filter 10 may be composed of a band magnet, and the second attachment member 25 provided on the filter coupling portion 21 may be composed of a magnetic susceptor . However, this is merely an example, and any of the first opposing face 10a and the second opposing face 21a can be attached to each other by a magnetic force.

According to one embodiment, the first attachment member 15 is attached so as to protrude from the first opposing face 10a, and the second opposing face 21a is provided with a groove (21b) is formed. The second attachment member 25 can be attached to the bottom surface of the groove 21b formed in the second opposing face 21a.

The grooves 21b formed in the second opposing face 21a may be formed as grooves of a rectangular trench structure having a narrow width and a long length, for example. Therefore, the second attachment member 25 attached thereto may also be configured to be attached in a rectangular shape to the groove bottom surface of the trench structure. According to the present embodiment, the first attachment member 15, which is attached to the filter 10 in a protruding manner, can also be configured to have a rectangular shape corresponding to the groove of the trench structure.

Fig. 10 is a view for explaining another embodiment of the ultrafine dust filter module shown in Figs. 4 and 5. Fig. 10 (a) shows the state before the outer frame is mounted, and FIG. 10 (b) shows the state after the outer frame is mounted. Referring to FIG. 10 first, differences between FIGS. 4 and 5 will be described.

Referring to FIG. 10, the ultrafine dust filter module 600 according to another embodiment of the present invention includes a filter 110 for filtering ultrafine dust contained in air, (60).

The coupling assembly 60 includes a main body portion 63 coupled to the screen frame P1, a filter coupling portion 61 capable of being positionally movably coupled to the main body portion 63, ). The ultrafine dust filter module 600 of FIG. 10 differs from the ultrafine dust filter module 200 of FIGS. 4 and 5 in that it further includes an outer frame 66. Hereinafter, the difference will be mainly described.

The filter 10 of FIGS. 4 and 5 is made to have a size enough to completely cover the first attachment member 15, but the filter 110 of FIG. 10 is manufactured so as not to completely cover the first attachment member 65 . Therefore, when the filter 110 is coupled to the filter coupling portion 61 shown in FIG. 10, a gap can be formed.

The outer frame 66 of the present embodiment has the effect of covering the gap in the case where the gap is formed and covering the gap due to the separation between the main body portion 63 and the filter engaging portion 61 at the same time.

That is, the main body portion 63 includes first main body portions 63a and 63b contacting the screening frame P1 when the second main body portion 63 is engaged with the screening frame P1, 63c. Since the filter coupling portion 61 is coupled only to the second body portion 63c, a spacing is generated between the filter coupling portion 61 and the first body portions 63a and 63b.
