１０２に接続する構成となつていた。Conventional Technology In recent years, when constructing buildings, there are many cases where the height of the building is restricted to a low level due to the issue of sunlight rights. but,
On the other hand, when considering the effective use of land or the construction cost per floor area, it becomes necessary to increase the number of floors.
For this reason, the height of each floor is kept low and there are many cases where no attic space is provided. However, as shown in FIG. 1, conventional duct ventilation fans always have a main body 101 protruding into the ceiling and are connected to a duct 102 in the ceiling.

という欠点を有していた。Problems to be Solved by the Invention With the above configuration, it was impossible to install it in a building without an attic. In addition, conventional duct ventilation fans are always attached to the ceiling, so in toilets and other places, odors generated at a low level near the floor are collected after being guided upward through the human nose.
When exhausting air, I often inhaled the odor and felt very uncomfortable. In addition, because conventional duct ventilation fans are fitted with different materials or designs on one surface, the ceiling, there are few cases where they blend well with the ceiling, making them very noticeable.
It has the disadvantage that it often disturbs the interior of the room.

and installed at the corner formed by walls 19 and 20,
The discharge duct 23 is passed through the wall surface 19, and the outdoor hood 22 is connected to the discharge duct 23. In addition, 17 in the figure shows the attic space, and 21 shows the toilet bowl. To explain the installation of the duct ventilation fan in more detail, first, a hole is made in the wall surface and the duct 23 is passed through, one end of the duct 23 is connected to the discharge port 55, and the other end is connected to the outdoor hood 22. Then, the back plate 7 is fixed to the wall using the mounting holes 9 with screws, and then the front plate 12 is fixed with the fixing screws 13. Then, the corner duct 15 is fitted and connected to the lower part of the ventilation fan main body 14.

There is no protrusion into the attic 17 of 4, and there is no protrusion into the attic 17.
Since there is no need for duct piping, the ventilation fan main body 14 can be installed even in buildings with low ceilings or buildings without ceilings. In addition, when installed in a toilet, etc., the corner duct 15 is connected to the lower part of the ventilation fan body 14, so regardless of the installation location of the ventilation fan body 14, the suction port can be installed near the toilet bowl 21, which is the source of odor. It is possible to collect odors extremely efficiently and realize comfortable ventilation in the toilet. Further, the ventilation fan body 14 can be installed at the corner where the wall surface 19 and the wall surface 20 intersect, and in addition, the corner duct 15 connected to the lower part of the ventilation fan body 14 has the same external shape as the ventilation fan body 14, so it is less noticeable and can be easily integrated into the interior. It is easy to harmonize and does not disturb the interior of the room.
