The effects set in this way will be described as follows.

First, when the size of the rear air inlet of the air cleaner is roughly divided, three types of 250 mm × 360 mm, 330 mm × 420 mm, and 350 mm × 530 mm are often seen.

When bonding with an adhesive is performed on the outer peripheral portion of these three types of rear intake ports, assuming that the width of the adhesive is 10.0 mm, the outer size of the adhesive portion 20 is 270 mm × 380 mm, 350 mm × 440 mm, It is only necessary to set 370 mm × 550 mm, and the sizes H81 to H86 and W81 to W86 described above are set so as to conform to this.

In the manufacture of the filter structure 80, the raw material is cut out and manufactured. However, since it is not cut at the place where the pressure-sensitive adhesive is applied, the size of the entire filter body 10 is provided with 5 mm on both sides as ears. 380 mm (W80) × 560 mm (H80).

When the air cleaner is attached to the rear intake port, the filter structure 80 is attached to the strips (21, 22, 81, 82) according to the vertical or horizontal size of the rear intake port of the air cleaner as described above. ) And the cross band portions (83 to 86), an adhesive pattern surrounding the periphery of the rear air inlet of the air cleaner can be obtained.

FIG. 16 is a plan view showing the external shape of the filter structure according to the sixth embodiment of the present invention, and corresponds to FIG.

Note that, since the description is basically the same as that according to the fifth embodiment, the difference will be mainly described.

Referring to the figure, in the sixth embodiment, in the adhesive portion 20 in the fifth embodiment, a fifth belt shape extending in parallel to the first belt portion 21 and the like is further provided. Section 91 and sixth strip 92, cross strips 93 and 94 extending substantially perpendicular to the first strip 21 and the like, and strips (21, 91, 92, 82, 81, 22) And a marking portion 95 provided in each region portion surrounded by the cross-band portions (83, 84, 85, 94, 93, 86).

The fifth belt-like portion 91 and the sixth belt-like portion 92 are respectively related to the center line connecting the centers of a pair of substantially rectangular short sides of the filter body 10, and the third belt-like portion 81 and the fourth belt-like portion. It is arranged so as to be symmetrical with the line 82.

The

cross band portions

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

The sign portion 95 is configured by a plurality of heart shapes, and when the use proceeds, dust adheres around the heart shape of the sign portion 95, so that the heart shape of the sign portion 95 rises, and indicates the 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 heart-shaped size in this way will be described below.

First, the back air inlet of the air cleaner is often formed in a lattice shape in which a plurality of substantially right-angled rectangular openings are arranged vertically and horizontally, 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 can be said that the size of the heart shape of the marker 95 is preferably set to 15 mm × 15 mm or less so as not to block the gap between the grids. On the other hand, considering the visibility when the use progresses and the heart shape is lifted, the size of the heart shape is preferably larger than 7 mm long × 6 mm wide or 6 mm long × 7 mm wide. From the above, it can be said that the size of the heart shape is preferably set to length 7 mm × width 6 mm or length 6 mm × width 7 mm, or length 7 mm × width 7 mm to length 15 mm × width 15 mm.

In addition, each heart shape included in the sign portion 95 is staggered in the respective region portions (21, 91, 92, 82, 81, 22) and cross-band portions (83, 84, 85, 94, 93, 86) are arranged so as not to overlap. Here, for example, the heart shape in a certain region portion B81 is arranged on a diagonal line L81 of 45 °, and the heart shape in another region portion B82 is arranged on a diagonal line L82 of 45 °. The line L81 and the line 82 are in a parallel relationship and are arranged so as not to intersect even if extended.

Here, when the filter structure 80 is attached to the rear intake port of the air cleaner, the heart shape may not be lifted well even if the use of the rear intake port of the air cleaner is advanced depending on the positional relationship with the lattice. By arranging as described above, it is possible to shift the positional relationship between the heart shape and the lattice of the back inlet of the air cleaner for each region part, so that it is possible to avoid that all the heart shapes do not float well it can.

In addition, in said 5th Embodiment and said 6th Embodiment, although the filter structure comprised from a specific number of strip | belt-shaped parts and crossed | belt-shaped part was demonstrated, the number is not restrict | limited. For example, in the fifth embodiment, it is also possible to provide a band-like portion and a cross-band-like portion similar to those in the sixth embodiment.

Further, in the sixth embodiment, the sign portion is configured by a plurality of heart shapes, but is not limited thereto. The labeling part may be composed of labeling elements such as other patterns and characters as long as the adhesive is applied in the form of a label indicating the replacement time of the filter structure. The labeling element may have a size within a range formed by a square or a rectangle having one side of 6 to 15 mm and the other side of 6 to 15 mm. If comprised in this way, it can suppress that a marker element prevents between the grating | lattices of the back surface inlet of an air cleaner, and the visibility of a marker element when use progresses increases. Thereby, the labeling element functions as a label indicating the replacement time of the filter structure more reliably.

Furthermore, in the sixth embodiment, the plurality of heart shapes are arranged in a staggered pattern in each region portion, but the present invention is not limited to this. The plurality of heart shapes can be configured to be spaced apart from each other. That is, a plurality of heart shapes may be formed in an island shape in the region portion.

Furthermore, in the sixth embodiment, the plurality of heart shapes are arranged on a specific line, but the present invention is not limited to this. As the plurality of heart shapes, it is possible to adopt a configuration in which the closest heart shapes are provided so as to be shifted from each other vertically or horizontally. Since dust adheres to the periphery of the marker element of the marker part more reliably, it can be avoided that the marker element of the marker part does not float well.

Further, although not specifically described in the fifth embodiment and the sixth embodiment, the filter structure is used for an air conditioner as described in the first embodiment. What was formed in size and cut by predetermined size may be used.
