A test was conducted to verify the effect of the filter structure 11 according to the first embodiment shown in FIG.
1. Test conditions First, test conditions for verifying the oil absorption amount (oil absorption amount) of the filter structure 11 will be described.

  The filter structure 11 according to this example is the same as the structure of the filter structure 11 according to the first embodiment described above, and therefore, the test conditions and the like are not repeated here without repeating the detailed description of the structure. The explanation will focus on the points.

Referring to FIGS. 1 and 4, the panel body 21 of the filter structure 11, the longitudinal length _{L 1} is a 350 mm, horizontal length _{L 2} is set to 450 mm. The area of the opening 22 of the panel body 21 is 950 cm ² .
Filter 41 Filter structure 11, the vertical length _{L 3} is 300 mm, the lateral length _{L 4} is set to 420 mm.

  The main component of the filter 41 of the filter structure 11 is polyethylene terephthalate (PET).

The application amount of the adhesive 31 of the filter structure 11 is 2.5 g / m ² .

The basis weight of the filter is 40 g / m ² .

  The application angle θ of the adhesive 31 with respect to the long side direction of the outer edge of the panel body 21 is 45 degrees.

Coating width _{W 1} and the coating interval _{W 2} of the adhesive 31 was performed by changing the conditions in 1mm units in the range of 1Mm～6mm. The adhesive 31 is applied portion (corresponding to the application width W ₁₎ and a non-coated portion 30 (corresponding to the coating interval W ₂₎ is so as to continuously alternate, is applied in a striped pattern. The application width W ₁ and the application interval W ₂ of the adhesive 31 were the same (W ₁ = W ₂ ). Further, the adhesive 31 is applied to the entire one surface 25 of the panel body 21.

  Next, conditions for installing the filter structure 11 will be described.

  FIG. 10 is a schematic front view showing a use state in which the filter structure according to the first embodiment shown in FIG. 1 is installed in the range hood.

  With reference to the drawing, the filter structure 11 is fixedly placed in contact with the lower surface of the range hood 1. There is a fan (not shown) at an upper position inside the range hood 1, and the gas is sucked upward by rotating the fan.

  A gas stove 3 is installed below the range hood 1. The frying pan 5 is placed on the upper surface of the gas stove 3. At this time, the distance H from the upper surface of the frying pan 5 to the lower surface of the filter structure 11 is about 70 cm. A frying device (not shown) for dripping water and oil is attached to the frying pan 5.

  Surrounding the gas stove 3, a wall 7 is installed on the left side of the gas stove 3, a wall 8 is installed on the back side of the gas stove 3, and a wall 9 is installed on the right side of the gas stove 3.

  Water and oil are dropped onto the frying pan 5 by a dropping device. At this time, the dropping speed is 1.3 drops / second of water and 1.0 drop / second of oil.

  The frying pan 3 is continuously heated for 30 minutes while water and oil are dripped from the dropping device to the frying pan 3 with the gas stove 3 set to the maximum heating power. Thereby, oil smoke is generated from the heated frying pan 3.

The fan inside the range hood 1 is rotated in the “strong” mode. With this configuration, approximately the generated oily smoke is sucked into the inside of the range hood 1 through the filter 41 of the filter structure 11.
2. Evaluation Method For each application width W ₁ (same as the application interval W ₂ ) of the adhesive 31, the “filter oil absorption possible area”, “filter oil absorption amount”, “adhesive application amount”, and “filter end portion” are evaluation items. Evaluation was performed by “adhesive strength”. Note that “entire coating” in the coating width W ₁ of the adhesive 31 indicates the filter structure 71 of the conventional example shown in FIG. 11 (in the case where there is no non-coated portion 30 where the adhesive 31 is not applied). Yes.

  The filter oil-absorbable area refers to an area in the filter 41 of the filter structure 11 through which gas containing oil can be vented. Therefore, when the application width is the entire surface application, the filter oil-absorbable area indicates the area of the filter 41 located in the opening 22 of the panel body 21. For other application widths, the total is the area of the filter 41 facing the opening 22 of the panel body 21 and the area of the filter 41 facing the ventilation path.

  The filter oil absorption indicates the amount of oil absorbed by the filter 41 when the frying pan 5 is heated for 30 minutes. The filter oil absorption is 3.5 g or more at the product level.

  The adhesive application amount is a percentage of the application amount of the adhesive 31 when the application width is the entire application, that is, when the amount of the adhesive 31 applied to the entire one surface 25 of the panel body 21 is 100%. .

The adhesive strength of the filter end portion is obtained by evaluating the adhesive strength at the outer end portion 42 of the filter 41 with “◎”, “◯”, and “×”.
3. Test results and evaluation The test results are shown in Table 1 below.

この表１を参照して、塗布幅Ｗ_１＝塗布間隔Ｗ_２の試験条件の下で試験を行ったので、塗布幅１ｍｍ〜６ｍｍにおける接着剤塗布量は５０％である。このとき、塗布幅が全面塗布のときのフィルター吸油可能面積は９５０ｃｍ^２であり、塗布幅が１ｍｍ〜６ｍｍのときのフィルター吸油可能面積は１０８０ｃｍ^２である。これは、塗布幅が１ｍｍ〜６ｍｍのときのフィルター吸油可能面積が、塗布幅が全面塗布のときのフィルター吸油可能面積より大きくなっているのは、通気路５０に面するフィルター４１の面積が加わったためである。

With reference to Table 1, since the test was performed under the test condition of coating width W ₁ = coating interval W ₂ , the adhesive coating amount in the coating width of 1 mm to 6 mm is 50%. At this time, the filter oil-absorbable area when the application width is the entire surface application is 950 cm ² , and the filter oil-absorbable area when the application width is 1 mm to 6 mm is 1080 cm ² . This is because the filter oil-absorbable area when the application width is 1 mm to 6 mm is larger than the filter oil-absorbable area when the application width is full-surface application, because the area of the filter 41 facing the air passage 50 is added. This is because.

  Here, the oil absorption amount of the filter is 3.8 g when the coating width is applied to the entire surface, 4.0 g when the coating width is 1 mm, 4.2 g when the coating width is 2 mm, and the coating width is 3 mm. It was sometimes 4.2 g, 4.3 g when the coating width was 4 mm, 4.3 g when the coating width was 5 mm, and 4.3 g when the coating width was 6 mm. Therefore, in the filter structure 11 provided with the air passage 50, the filter oil absorption increased as compared with the conventional filter structure 71 coated on the entire surface. Further, the oil absorption amount of the filter when the coating width is 1 mm to 6 mm is all 3.5 g or more, which is acceptable at the product level, and the effect was verified.

  The adhesive strength of the filter end was “◎” when the coating width was applied over the entire surface, and was “◯” when the coating width was 1 mm to 6 mm. Accordingly, there was no evaluation of “x”, and all of the coating widths of 1 mm to 6 mm were able to withstand use as a product level.
