DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings. In the drawings, reference numeral 1 denotes a casing.
Is formed of a hollow body obtained by blow molding a thermoplastic resin, and a mounting portion 2 of a ventilation fan at a lower portion thereof and a duct 3 extending upward are integrally formed. A ventilation fan 4 is attached to the attachment portion 2 of the ventilation fan.

The casing 1 has a rear surface 5 which is flat, and the mounting portion 2 of the ventilation fan is formed by forming a fan fitting recess 7 in a concave portion 6 which is recessed inward from the rear surface 5. The fan fitting recess 7 is opened to a hollow portion by a circular opening 8 and communicates with the duct 3. A cover 10 is connected to the lower end of the fan mounting portion 2 by a hinge 9 which is compressed and thinned so as to be openable and closable.
Is a fan fitting recess 1 that is fitted with the fan fitting recess 7
1, the fan fitting recess 11 is provided with a circular opening 12. The cover 10 is fitted to the recessed portion 6 by the hinge 9 so that the fan fitting recess 7
To fix the ventilation fan 4 fitted to the nip. The cover 10 locks and holds the latch 14 on the latch receiving portion 13. The cover 10 is provided with a ventilation opening 16 on the wall 15 of the building.
The ventilation fan 4 is fixed to the ventilation opening 16 of the wall 15 of the building by the flange 17. 18 is a mounting bracket, the casing 1 above
The back of the building is flat as shown on the outside of the building wall 15.
It is facing the back. The casing 1 is attached to the wall 15 of the building with a mounting bracket 18 using screws or the like.

On the other hand, the upper end surface 19 of the duct 3 has a flat surface having the same width as the front-rear width of the duct 3.
An inclined surface 20 that projects obliquely downward and forward from the front end of the duct 9 is formed at the upper end of the duct 3 as a space 22 having a larger volume than the passage 21 of the duct 3. Also,
The duct 3 is formed with a rib 3a projecting toward the passage 21 and extending in the air blowing direction, thereby preventing deformation of a casing including a guide for blowing air and a mounting portion 2 of the ventilation fan 4. The upper end face 19 has an exhaust hole 2 facing upward.
3 has an exhaust hole 25 at the lower end surface 24 of the inclined surface 20.
Each is provided. A solar cell 26 is provided outside the inclined surface 20, and the solar cell 26 supplies electric power for driving the ventilation fan 4. 27
Indicates wiring for this purpose. The driving power of the ventilation fan 4 may be supplied from another power source without depending on the solar cell 26. In order to increase the power generation efficiency of the solar cell 26, it is desirable to set the angle of the inclined surface 20 with respect to the horizontal plane to be equal to or close to the latitude of the installation location. 28 is a drain hole for drainage.

The thermoplastic plastic constituting the casing 1 is polyethylene, polypropylene, polyvinyl chloride, ABS resin or the like suitable for blow molding.

According to the ventilating apparatus according to the embodiment configured as described above, the casing 1 is formed by integrating the mounting portion 2 of the ventilation fan and the duct 3 extending in the exhaust direction with a hollow body formed by blow molding. Since the ventilation fan 4 is attached to the attachment portion 2 of the ventilation fan of the casing 1, the exhaust direction of the ventilation by the ventilation fan 4 is
Can be located above. For this reason, it is possible to perform exhaust at a position that does not interfere with people or other things without being restricted by the position of the ventilation port 16 of the building.
Further, the exhaust gas flowing into the space portion 22 through the passage portion 21 of the duct 3 is exhausted from the exhaust holes 23 and 25 provided on the upper end surface 19 and the lower end surface 24 of the inclined surface 20, respectively.
The exhaust positions are dispersed, and the exhaust air pressure can be reduced. In particular, since the volume of the space 22 is larger than that of the passage 21 of the duct 3, the wind pressure of the exhaust flow in the space 22 is reduced, and the exhaust air pressure from the exhaust holes 23 and 25 can be further reduced. . In addition, the ventilation device according to the present invention
According to the arrangement, the one-piece structure is taken from the outer surface of the building wall 15
Because it is installed, there is no room in the internal space of the building
But it can be installed without any trouble. In the embodiment described above, an example in which ventilation is performed from the inside of the building to the outside is shown. And can be used for ventilation with other spaces. Further, the positions and numbers of the ventilation holes 23 and 25 are not specified in the illustrated example, and the ventilation holes may be formed on the side wall. Further, the casing 1 does not necessarily need to include the cover 10, and the ventilation fan 4 can be provided without using the cover 10.
Can be attached to the casing 1.

[0011]

According to the present invention, a casing is provided in which a mounting portion of a ventilation fan and a duct extending in a ventilation direction are integrated, and the direction of exhaust is controlled by a person regardless of the position of a ventilation opening of a building where the ventilation fan is located. and other can be a position that does not interfere with respect to one, moreover, be an integral structure, the can be easily performed, such as mounting and removal Tomo
Inside the building by mounting it from the outside of the building wall.
Even if there is not enough space, it can be installed without any trouble
The effect that can be obtained is obtained.
