気扇を提供するものである。 When inspecting or repairing a conventional duct ventilation fan, as shown in Fig. 1, it is necessary to leave the duct connection part 101 in the ceiling and remove the ventilation fan body 102 itself, which is not easy to do and also requires a lot of work. There is a drawback that the airtightness between the duct connection part 101 and the duct 103 and between the ventilation fan main body 102 and the duct connection part 101 deteriorates each time, and the performance of the ventilation fan main body is also impaired. The present invention eliminates these conventional drawbacks and provides a duct ventilation fan that is easy to maintain, such as inspection and repair.

枠、１８はうちわボルトである。 Embodiments of the present invention will be described below with reference to FIGS. 2 to 4. FIG. 2 is a side sectional view of one embodiment of the present invention, and FIG. 3 is an exploded perspective view of the main parts thereof. In these figures, 1 is a box-shaped ventilation fan body that has a side intake port 2 on one side and a duct connection port 3 on the other side. Blower 4 to discharge
is built-in. Reference numeral 5 denotes a sound absorbing material provided on the inner wall between the side air intake port 2 and the blower 4 of the main body 1.
A ventilation box 6 has a side outlet 7 on one side that matches the side intake 2 of the ventilation fan main body 1, and has a substantially fan-shaped top with a lower intake 8 formed at the bottom. A material 9 is provided. A hook 10 is attached to the lower part of the side intake port 2 of the ventilation fan body 1.
However, screw holes 11 are provided in the upper and lower parts of the side air intake port 2, respectively, and an engagement hole 12 that engages with the hook 10 is provided below the side air outlet 7 of the ventilation box 6. Furthermore, through holes 13 are provided in the upper and lower parts of the side outlet at positions that match the screw holes 11 provided in the ventilation fan main body 1. Reference numeral 14 denotes a decorative grill provided to cover the lower suction port 8 of the ventilation box 6, and is detachably attached to the ventilation box 6 by a spring piece 15. 16 is a reinforcing frame provided on the upper part of the ceiling board 17, and 18 is a fan bolt.

クス６に取り付ける。 During construction, the ventilation fan main body 1 configured as described above is attached to the reinforcing frame 16 in the ceiling, and the ventilation fan main body 1 is positioned to the side of the ventilation opening formed in the ceiling board 17. Next, hook the engagement hole 12 of the ventilation box 6 onto the hook 10 of the ventilation fan body 1, align the side outlet 7 of the ventilation box 6 with the intake port 2 on the side of the main body, and insert the fan bolt 18 into the hole formed in the ventilation box 6. After connecting the ventilation box 6 to the ventilation fan main body 1 by passing it through the hole 13 and screwing it into the screw hole 11 of the main body, the decorative grill 14 is attached to the ventilation box 6 by the spring piece 15.

を軽減することができる。 Since there is no need to move the ventilation fan body in this way, there is no need to attach or disconnect the cord to connect the ventilation fan body to a power source, and maintenance work can be performed while the ventilation fan body is fixed.
Since the airtightness around the duct connection port 3 is not impaired, maintenance work such as inspection and repair becomes extremely easy, and the workability can be improved. Further, since the noise emitted from the ventilation fan main body 1 is configured to pass once through the ventilation box, it is absorbed by the sound absorbing material 9 inside the ventilation box, thereby reducing the noise.
