As shown in FIG. 1 and FIG. 2, the ventilator main body 1 is installed in an attic space or a first floor ceiling space in a building, and fresh fresh air is introduced from an outside air supply port 2 to be incorporated therein. Is supplied to the room through the indoor air supply port 4. At this time, the outside air introduced from the outside air supply port 2 is mixed with coarse dust, insects, and the like floating in the vicinity of the outside air supply port 2. On the other hand, the indoor polluted air is introduced from the indoor exhaust port 5, passes through the heat exchange element unit 3, and is exhausted to the outside through the outdoor exhaust port 6. At this time, the heat exchange element unit 3 has a function of recovering the amount of heat of the exhaust air into the supply air. Fresh outdoor air introduced from the outside air supply port 2 and indoor contaminated air introduced from the indoor exhaust port 5 are exhausted through an air supply fan 9 connected to the motor 7 on the same shaft 8 via the heat exchange element 3. It is transferred by the fan 10 for use.
[0025]
Further, the ventilator main body 1 has a path for exhausting some indoor polluted air introduced from the local exhaust port 11 to the outside through the outdoor exhaust port 6 by the exhaust fan 10 without passing through the heat exchange element unit 3. Further, as shown in FIG. 3, the local exhaust port 11 provided for sucking indoor air is provided on any one of the main body left and right side exhaust ports 12, the main body top surface exhaust port 13, and the main body air supply port installation surface 14. The ventilator body 1 is communicated through a connected duct.
[0026]
In addition, since dust and insects are mixed in the air introduced from the outside air supply port 2, insect traps installed at the outside air intake port 44 communicated with the outside air supply port 2 through a duct. Coarse dust / insects are collected by the coarse dust / insect filter 15 as a part, and finer dust is collected by an air supply cleaning filter 16 provided adjacent to the downstream side of the coarse dust / insect filter 15, After being cleaned, it is supplied to the room. On the other hand, the dust mixed in the indoor polluted air is collected by the exhaust filter 18 attached to the decorative panel 17 installed in the indoor exhaust port 5 as shown in FIG.

However, when the dirt is severe, the insect filter cover 22 and the insect trapping box 21 are removed. Can be separated by sliding and cleaned. Since the insect collecting box 21 has a box shape having a predetermined depth by the frame 20, even if a large amount of insects are collected, the pressure loss is reduced and the ventilation performance is improved. It does not reach a significant drop. In addition, when discarding insects, the coarse dust / insect filter 15 is carried out with the insect filter cover 22 facing up and the insect collection box 21 facing down, and in a disposal place (for example, a trash can), If the filter cover 22 for insect protection and the insect collection box 21 are separated while sliding, insects and the like can be cleaned cleanly without getting in the hands or falling into the room. Further, the separation structure of the insect collecting box 21 and the insect filter cover 22 can be realized not only by a slide structure but also by a fitting method using a plurality of claw portions 32.
[0028]
Further, when the insect collection box 21 and the insect filter cover 22 are combined, the gap between the two is set to 0.3 mm or less, so that fine dust and insects can be reliably collected. The filter 19 of the insect collection box 21 is integrally formed with the frame body 20 to prevent deformation, and a constant ventilation volume can be secured by always maintaining a constant collection volume.
[0029]
By the way, the filter 19 is composed of a fine net having a mesh interval of 0.5 mm or less, and can surely collect fine insects and the like. Polyethylene nets are weatherproof and water resistant compared to polypropylene and nylon.

The filter case 33 has a plurality of grooves 34 having different shapes, and filters for various applications can be mounted as necessary. Further, the material forming the filter case 33 can be replaced with resin and metal. The groove 34 is formed in a shape that determines the mounting direction of various filters. Various types of filters include medium-performance pollen filters, high-performance dust collection filters, and nitrogen oxide removal filters.
[0034]
The filter case 33 is removed when the air supply cleaning filter 16 is cleaned. At this time, since the dust / insect filter 15 is attached to the adapter 27, the collected dust / insects and the like are not dropped. It can be easily visually observed. Further, since most of the dust is removed by the coarse dust / insect-proof filter 15, the collection life of the adjacent air supply / cleaning filter 16 can be extended. The heat exchange element 3 is independent of the filter case 33 and is located further downstream, so that it is not necessary to remove it when cleaning the coarse dust / insect repellent filter 15 or the air supply cleaning filter 16.
[0035]
The exhaust filter 18 provided on the decorative panel 17 installed in the indoor exhaust port 5 can be directly cleaned with a vacuum cleaner during cleaning, and can be removed and cleaned because it can be attached and detached with the knob 35.
