That is, the feature of the present invention is that a pend cap is installed at the opening end of the ventilation duct on the outer wall of the building, and an insect screen is removably attached in the middle of the ventilation duct located on the indoor side, and the ceiling surface below the insect screen is [Function] According to the above structure, the insect screen can be cleaned and replaced by working from the indoor side.
以下、本発明の実施例を図面に基づいて説明する。 Embodiments of the present invention will be described below based on the drawings.
第１図〜第３図は、本発明の一実施例を示す。1 to 3 show an embodiment of the present invention.

には、８６を有する点検ロアが形成されている。In the figure, 1 is an outer wall of a building such as an apartment complex, and 2 is a ceiling. Reference numeral 3 denotes a ventilation duct installed in the ceiling, one end of which opens into the outer wall 1, and the other end communicating with the room via a ventilation fan (not shown). Reference numeral 4 denotes a pendocap at the opening end of the ventilation duct installed on the outer wall 1, and this pendocap 4 does not have an insect screen that can cause clogging. In the middle of the ventilation duct 3 located on the indoor side, an insect screen 145 is removably attached at a position as close to the outer wall 1 as possible, and an insect screen 86 is installed on the ceiling below the insect screen 5. An inspection lower is formed.

に套嵌されている。Various structures can be adopted for attaching the insect screen 5 to the middle of the ventilation duct 3 in a detachable and replaceable manner.
In this embodiment, as shown in FIG. 3, a part of the ventilation duct 3 is formed by an expandable bellows-like duct 1-3A, and a connecting flange portion 8 formed at one end of the bellows-like duct 3A.
The peripheral edge of the insect screen 5 is sandwiched between the flange portion 9a of the duct joint 9 provided opposite thereto, and the butterfly napfts 11 are attached to the fixing bolts 10 that pass through these.
The peripheral edge of the insect screen 5 is fixed by screwing it on. In the figure, reference numeral 12 indicates an attachment band of the bellows-shaped duct 3A, and reference numeral 9b indicates a cylindrical portion of the duct joint 9, which is tightly fitted into the ventilation duct 3.
