(Embodiment 2)
6 and 7, the same components as those in FIGS. 1 to 5 are denoted by the same reference numerals, and detailed description thereof is omitted.

  In the first embodiment, the handle 17 of the insect collecting section 13 shown in FIG. 2 is configured on the same surface as the lower surface of the main body 1. However, in the second embodiment, the handle 17 is the same as the indoor surface 27 of the louver 22 as shown in FIG. The difference is that the handle 17 is formed on the surface. Moreover, since the structure of the junction part of the insect collection part discharge port 12 and the upper opening 14 of the insect collection part 13 differs in connection with it, a detail is shown below.

  As shown in FIG. 6, a louver 22 is attached to the main body 1 so as to cover a square opening opened in the ceiling plate 23, and is attached along the ceiling plate 23 with the ceiling plate 23 sandwiched therebetween. . The louver 22 is formed of a louver frame 24 and a louver panel 25, and the louver panel 25 is provided with an opening into which the insect collecting portion 13 is inserted. The insect trapping part 13 is inserted into the opening from below to be accommodated, and the insect trapping part 13 is fixed to the louver panel 25, and the handle 17 is located on the same surface as the indoor surface 27 of the louver 22 when fixed.

The insect trapping part 13 can be easily removed from the indoor side without spilling dust or the like.

  In addition, since the main body 1 is constructed on the back of the ceiling 21 and the louver 22 is attached to the main body 1 via the ceiling plate 23, the interior surface of the main body 1 and the louver 22 depends on variations in the thickness of the ceiling plate 23 and the construction method. The distance to 27 is not always fixed. Therefore, since the handle 17 of the insect collecting unit 13 is located on the same surface as the indoor surface 27 of the louver 22, the insect collecting unit discharge port 12 formed in the upper opening 14 of the insect collecting unit 13 and the main body 1. The distance between and is not fixed, and there is a possibility that a gap will be formed.

  Therefore, as shown in FIG. 6, the insect trapping portion discharge port 12 is composed of an inner frame 28 and an outer frame 29, and when the insect trapping portion 13 is attached to the main body 1, the upper opening frame 20 is the inner frame. 28 and the outer frame 29, and the airtightness between the insect collecting portion discharge port 12 and the upper opening 14 is improved. Further, by setting the gaps between the upper opening frame 20 and the inner frame 28 and the outer frame 29 to be 0.3 mm or less, it is possible to reliably collect fine dust and insects. With the above configuration, the distance between the insect collecting portion discharge port 12 and the upper opening 14 is not fixed due to the difference in the thickness of the ceiling 21, but the upper opening between the inner frame 28 and the outer frame 29 is not determined. In order to fill the gap by accommodating the frame 20, the upper opening frame 20 always remains even when the vertical distance of the length of the inner frame 28 and the outer frame 29 and the position of the upper opening 14 of the insect collecting portion 13 change. Is accommodated in contact with the inner frame 28 and the outer frame 29, and airtightness can be maintained.

  Further, the shapes of the inner frame 28 and the outer frame 29 are such that the distance between the inner frame 28 and the outer frame 29 is wide at the tip, and the distance becomes narrower as it goes upward, and further upward, the inner frame 28 and the outer frame 29 The distance to is constant. By adopting such a shape, when the insect trapping portion 13 is pushed upward and fixed to the main body 1, the entrance between the inner frame 28 and the outer frame 29 is sufficiently wide with respect to the upper opening frame 20. For this reason, since the upper opening frame 20 can be reliably inserted, the operability of attaching the insect collecting portion 13 to the main body 1 can be improved.

  Further, when the inner frame 28 and the outer frame 29 are preferably formed of an elastic body such as rubber, when the insect trapping portion 13 is pushed up and fixed to the main body 1, the upper opening frame 20 has the inner frame 28 and the outer frame 28. Although interfering with the frame 29, the inner frame 28 and the outer frame 29 are elastic bodies, so that the insect trapping portion 13 can be pushed up while being deformed. With such a configuration, since the upper opening frame 20, the inner frame 28, and the outer frame 29 interfere with each other, the airtight performance can be kept high. 14 can prevent the intrusion of coarse dust and insects due to air leakage from the gap with 14, and does not require a large force when operating the insect collecting section 13, thereby facilitating maintenance. it can.

  The ventilator according to the present invention allows the insect trapping part to be easily removed without spilling dust collected in the insect trapping part when cleaning the insect trapping part. It is also useful as an air cleaning device used to clean air.
