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.

If bonding with an adhesive is performed at the outer periphery of these three different sizes of the back inlet, assuming that the width of the adhesive is 10.0 mm, the outer size of the fixed portion 20 (outer size of the outer peripheral portion) is: It is only necessary to set 270 mm × 380 mm, 350 mm × 440 mm, 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 band-like portion (82, 83, 82) of the lattice portion according to the vertical or horizontal size of the rear intake port of the air cleaner as described above. 84, 85), a pressure-sensitive adhesive pattern surrounding the back of the air cleaner is obtained.

FIG. 17 is a plan view showing the external shape of the filter structure according to the ninth embodiment of the present invention, and corresponds to FIG.

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

Referring to the figure, in the ninth embodiment, in the fixing portion 20 in the eighth embodiment, further, in the lattice portion, extends in parallel to the first belt-like portion 41 and the like. A ninth belt portion 91 and a tenth belt portion 92, and an eleventh belt portion 93 and a twelfth belt portion 94 extending so as to be substantially orthogonal to the first belt portion 41 and the like are included. Further, the fixing portion 20 is a region portion surrounded by the belt-like portion (41, 42, 43, 81) of the outer peripheral portion and the belt-like portion (82, 83, 84, 85, 91, 92, 93, 94) of the lattice portion. It includes a sign 95 provided inside.

The ninth strip portion 91 and the tenth strip portion 92 are respectively related to the center line connecting the centers of the pair of short sides of the substantially rectangular shape of the filter body 10, and the fifth strip portion 82 and the sixth strip portion 83 so as to be symmetrical with the line 83.

The eleventh strip portion 93 and the twelfth strip portion 94 are respectively related to the center line connecting the centers of the pair of long sides of the substantially rectangular shape of the filter body 10, and the seventh strip portion 84 and the eighth strip portion. 85 and line symmetry.

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 mark portion 95 is staggered in each region portion (41, 42, 43, 81, 82, 83, 84, 85, 91, 92, 93, 94). 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 the eighth embodiment and the ninth embodiment described above, the filter structure composed of a specific number of belt-like portions has been described, but the number is not limited. For example, in the above-described eighth embodiment, it is possible to provide a belt-like portion similar to that in the above-described ninth embodiment.

Although not specifically described in each of the above embodiments, the labeling portion in the filter structure according to the ninth embodiment is the same as that of the eighth embodiment or the first embodiment. It is also possible to employ the filter structure according to the seventh to seventh embodiments.

Furthermore, in the ninth embodiment described above, the marker portion is formed 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 ninth 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 ninth 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 eighth embodiment and the ninth embodiment, the filter structure is used for an air conditioner as described in the sixth embodiment. What was formed in size and cut by predetermined size may be used.

Hereinafter, the present invention will be specifically described based on examples. The present embodiment is not limited to the examples.
I. Configuration of filter structure used in test As an example, a filter structure in which the fixing portion of the adhesive pattern shown in FIG. 1 and the like is formed on the filter body made of the nonwoven fabric as described above (that is, the first embodiment) 7) with different weight per unit area and air flow rate.

Examples 1 to 7 are configured such that the air flow rate of the filter body measured based on the JIS L 1096 A method (Fragile method) falls within the range of 1500 to 5000 cc / cm ² / sec.

Further, as Comparative Example 1, a filter main body made of a non-woven fabric was prepared which does not have a fixing portion as in Examples 1 to 7. The basis weight and the air flow rate of Comparative Example 1 are set to 40 g / m ² and 4654 cc / cm ² / sec, as in Example 2.

Furthermore, as Comparative Example 2, a case where a filter was not provided at the rear inlet of the air cleaner was also examined.

The sizes in Examples 1 to 7 and Comparative Example 1 are as follows.

・ Vertical length: Approximately 38cm
-Horizontal length: about 26cm
II. Details and Results of Test As described above, using the seven types of filter structures of Examples 1 to 7, as shown below, each of the target models of the air cleaner was fixed with an adhesive. The test was carried out by mounting through the part.

Moreover, about the comparative example 1, the surface fastener was stuck on the four corners of the outer peripheral part of the back surface intake port of an air cleaner, and it attached to the back surface intake port of the air cleaner through the surface fastener, and the following tests were done. .

Moreover, about the comparative example 2, the following tests were done, without attaching a filter to the back surface inlet port of an air cleaner.
1. Air Cleaner Target Model Sharp Corporation Product Number: KI-FX55-W
External dimensions (mm): width 392 x depth 265 x height 635
Rear inlet size (mm): Width 227 x Height 345
2. Test Contents (1) Air Purifier Internal Filter Status Confirmation Test For Examples 1 to 7 and Comparative Example 1, the filter structure is such that the rear air inlet of the air cleaner is completely covered by the rear air inlet. After attaching the body, start driving and set the automatic operation mode, continue 24 hours a day for 2 weeks, and then visually check the internal filter (HEPA filter, etc.) of the air cleaner. Confirmed.

In Comparative Example 2, the operation of the air purifier was started without a filter, and the operation was continued for 24 hours a day for 2 weeks in the state set to the automatic operation mode. The contamination of the (HEPA filter etc.) is visually confirmed.

The results were as shown in Table 1 below.

Referring to Table 1, “Small dirt around the inner filter frame of the air cleaner” is “small” and no dirt is accumulated around the inner filter frame of the air cleaner. The evaluation was made in three levels, “large” and “medium” between “small” and “large”.

As a result, in Examples 1 to 7, it was “small”. In Comparative Example 1, it was “medium”. Furthermore, in Comparative Example 2, it was “large”.

In Comparative Example 2 in which no filter was attached, dust contamination was relatively accumulated. Even in Comparative Example 1, dirt is reduced compared to Comparative Example 2 in which no filter is attached. However, if the four corners of the filter body are simply fixed with hook-and-loop fasteners, dust will be removed from the unfixed part to the internal filter side of the air cleaner It is presumed that it invades. In conclusion, it can be said that the antifouling performance of Examples 1 to 7 in which the filter structure is attached to the air purifier via the fixing part in which the adhesive is applied in a square shape is superior.
(2) Air purifier abnormality confirmation test / abnormal noise detection test After the filter structure is attached to the air purifier, operation is started and whether abnormal noise different from normal operating noise is generated. This was confirmed by a sensory test.
・ Cleaning sign confirmation test After attaching the filter structure to the air cleaner, after the start of operation, it was confirmed whether the cleaning sign lights up. In the target model, the cleaning sign lights up when the filter is clogged. If it lights up, it is considered that the air permeability of the filter structure is low.

The results were as shown in Table 2 below.

Referring to Table 2, in the abnormal noise detection test, those where no abnormal noise was confirmed are marked with ◯, and those where abnormal noise was confirmed are marked with X. Also, in the cleaning sign confirmation test, if the cleaning sign is not lit, the mark is marked with ○, and if the cleaning sign is lit, the mark is marked with x.

As a result, for Examples 1 to 4 in which the air flow rate is set to 1500 cc / cm ² / sec or more, all were evaluated as “good”, while the air flow rate was set to 1342 cc / cm ² / sec or less. Examples 5 to 7 were all evaluated as x.

As described above, the filter structure for an air cleaner according to the present invention and the intake structure of the air cleaner to which the filter structure is attached are suitable, for example, for adhering to an object and filtering the passing gas. .
