The effects of setting in this manner are described below.

  First, the size of the rear air intake of the air purifier can be roughly classified into three types of 250 mm × 360 mm, 330 mm × 420 mm, and 350 mm × 530 mm.

  Assuming that the adhesive has an adhesive width of 10.0 mm at the outer peripheral portion of the rear air intake opening of these three sizes, the size of the outer shell of the adhesive portion 20 is 270 mm × 380 mm, 350 mm × 440 mm, The size of 370 mm × 550 mm may be set, and each size of the above-mentioned H81 to H86 and W81 to W86 is set to be adapted to this.

  In addition, although the raw fabric is cut out and manufactured in the manufacturing of the filter structure 80, the size of the entire filter main body 10 is provided with the portions to be the ears 5 mm on both sides since the filter body 10 is not cut. It becomes 380 mm (W80) x 560 mm (H80).

  When attaching the air purifier to the back air intake, the filter structure 80 may be a strip (21, 22, 81, 82) depending on the size of the back air intake of the air purifier as described above. Cut along the cross-strips (83-86) provides an adhesive pattern that surrounds the back inlet of the air purifier.

  FIG. 16 is a plan view showing the outer appearance of a filter structure according to a sixth embodiment of the present invention, which corresponds to FIG.

  In addition, since it is fundamentally the same as that of 5th Embodiment in description, it demonstrates focusing on the difference.

  Referring to the figure, in the sixth embodiment, a fifth strip extending in parallel to first strip 21 and the like is further provided in adhesion portion 20 in the fifth embodiment. Bands (21, 91, 92, 82, 81, 22) and cross-strips 93 and 94 extending substantially orthogonal to the portion 91 and the sixth strip 92, and the first strip 21 and the like And mark portions 95 provided in respective area portions surrounded by the cross bands (83, 84, 85, 94, 93, 86).

  The fifth band-shaped portion 91 and the sixth band-shaped portion 92 respectively relate to a center line connecting centers of a pair of short sides of the substantially rectangular shape of the filter main body 10, the third band-shaped portion 81 and the fourth band-shaped portion It is arranged in line symmetry with 82.

  The cross strip portions 93 and 94 are arranged so as to be line-symmetrical to the cross strip portions 84 and 85 with respect to a center line connecting the centers of a pair of long sides of the substantially rectangular shape of the filter main body 10, respectively.

  The marking portion 95 is formed of a plurality of heart shapes, and dust adheres to the periphery of the heart shape of the marking portion 95 when use progresses, so that the heart shape of the marking portion 95 is lifted to indicate replacement time of the filter structure 80 be able to. The size of the heart shape is not particularly limited, but is preferably set to 13 mm × 13 mm.

  The effect of setting the size of the heart shape in this manner will be described below.

  First, the back air inlet of the air purifier is often formed in a lattice shape in which a plurality of substantially rectangular square openings are aligned in the longitudinal and lateral directions, and the lattice size of the lattice is 15 mm × It may be set to 15 mm.

  In the case of such a grid size of 15 mm × 15 mm, it is preferable to set the size of the heart shape of the marker part 95 to 15 mm × 15 mm or less so as not to close the gap between the grids. On the other hand, it is preferable that the size of the heart shape is larger than 7 mm long × 6 mm wide or 6 mm long × 7 mm wide, in consideration of the visibility when the use progresses and the heart shape rises. From the above, it is preferable to set the heart-shaped size to 7 mm long × 6 mm wide or 6 mm × 7 mm wide, or 7 mm long × 7 mm wide to 15 mm long × 15 mm wide.

  In addition, each heart shape included in the marking portion 95 is in the form of a zigzag band (21, 91, 92, 82, 81, 22) and a cross band (83, 84, 85, 94) in the respective area parts. 93, 86) are arranged so as not to overlap with each other. Here, for example, the heart shape in a certain area portion B81 is arranged on the oblique 45 ° line L81, and the heart shape in another area portion B82 is arranged on the oblique 45 ° line L82, The line L81 and the line 82 are parallel to each other, and are arranged so as not to cross each other even if they are extended.

  Here, when the filter structure 80 is attached to the back intake port of the air purifier, the back intake port of the air purifier may not have a well-shaped heart shape depending on the positional relationship with the grid even if the use progresses. By arranging as described above, it is possible to shift the positional relationship between the heart shape and the lattice of the back air intake opening of the air purifier for each area part, so that it is possible to avoid that all the heart shapes do not float well. it can.

  In the fifth embodiment and the sixth embodiment described above, the filter structure constituted of the specific number of band portions and the cross band portion has been described, but the number is not limited. For example, in the fifth embodiment described above, it is also possible to provide strip portions and cross strip portions similar to those in the sixth embodiment described above.

  Moreover, in said 6th embodiment, although the label | marker part was comprised by several heart shape, it is not restricted to this. The marking portion may be made of a marking element such as another pattern or character as long as the pressure-sensitive adhesive is applied in the shape of a mark indicating the replacement time of the filter structure. Also, the marking element may be sized to fit within a range formed by a square or rectangle having a side of 6 to 15 mm and the other side of 6 to 15 mm. In this way, the marking element can be prevented from blocking between the air inlet back grids and the visibility of the marking element can be increased as usage progresses. This allows the labeling element to function as a marker that more reliably indicates when to replace the filter structure.

  Furthermore, in the sixth embodiment described above, the plurality of heart shapes are arranged in a staggered manner in each area portion, but the present invention is not limited to this. The plurality of heart shapes can be configured to be spaced apart from one another. That is, in the region portion, a plurality of heart shapes may be formed to be scattered like islands.

  Furthermore, in the sixth embodiment described above, the plurality of heart shapes are arranged on a specific line, but the invention is not limited to this. The plurality of heart shapes can adopt a configuration in which the closest heart shapes are provided in the upper, lower, left, or right side mutually shifted. As dust adheres to the periphery of the marking element of the marking part more reliably, it is possible to avoid that the marking element of the marking part is not lifted up properly.

  Furthermore, although not particularly described in the fifth embodiment and the sixth embodiment described above, the filter structure is used for an air conditioner as described in the first embodiment described above. What is formed in the size may be cut in a predetermined size.
