Description of the Related Art Conventionally, a so-called underfloor ventilation fan for ventilating under a floor of a building, as shown in FIG. 4, includes a ventilation fan body 1 provided with a blowing means, a ventilation fan body fixing panel 2 to which the ventilation fan body 1 is attached, a front panel 3, It is constituted by a shielding plate 5 which closes a part of the slit portion 4 opened in the front panel 3.

At the time of construction, the ventilation fan main body 1 is attached to the ventilation fan main body fixing panel 2, and the ventilation fan main body fixing panel 2 is attached to the foundation 7 in accordance with the ventilation holes 6 under the floor.

[0004] The shielding plate 5 closes a part of the slit portion 4 opened in the front panel 3 (that is, a portion larger than the ventilation portion of the ventilation fan main body 1), and the upper end surface and the lower end surface of the front panel 3. The upper end piece 5a and the lower end piece 5b which are protruded are cut off. The shielding plate 5 is sandwiched between the front panel 3 and the ventilation fan main body fixing panel 2, and the front panel 3 is It is fixed to the ventilation fan main body fixing panel 2.

[0005] A slit portion 4 opened in the front panel 3
The reason why part of the above is closed by the shielding plate 5 is as follows.

In other words, when the dimensions of the ventilation fan mounting structure are standardized so that the underfloor ventilation fan can be commonly used in each building, the outer wall 1 may be damaged due to the difference in the design of the individually built buildings.
When the space between the ventilation fan 4 and the underfloor ventilation hole 6 is small, the ventilation fan main body 1 is moved to the upper part of the panel 10 and fixed.

When the distance between the ground 15 and the underfloor ventilation hole 6 is small, the ventilation fan body 1 is moved to the lower part of the panel 10 and fixed.

In view of the above, it is necessary to raise and lower the ventilation fan body 1 in accordance with the position of the underfloor ventilation hole 6 of the individually built building, and to fix the ventilation fan body 1 at a predetermined position of the ventilation fan body fixing panel 2. On the other hand, the slit portion 4 which is the ventilation opening of the front panel 3 must be larger than the ventilation portion of the ventilation fan main body 1 on the other hand. Unless a part of the opened slit portion 4 (that is, a portion larger than the ventilation portion of the ventilation fan main body 1) is closed by the shielding plate 5, the circulation by the ventilation of the ventilation fan main body 1 cannot be prevented.

As described above, the front panel 3 is moved up and down in accordance with the position of the underfloor ventilation hole 6 of the individually constructed building, and the ventilation fan main body is placed at a predetermined position on the ventilation fan main body fixing panel 2. When fixing 1, there is also an advantage that the opening 8 of the ventilation fan main body fixing panel 2 is hidden.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described with reference to FIGS.

As shown in FIG. 1, the ventilation fan body 1 is provided with a blower (suction type) in a direction indicated by an arrow 9a or an arrow 9a.
Either of the blowing means (push type) in the direction shown by b is provided.

The ventilation fan body 1 is provided with an elongated hole 10 (see FIGS. 2 and 3 described later) for fixing the ventilation fan body 1 to the front panel 3.

Further, the ventilation fan body 1 and the shielding plate 11 are integrally formed, and the front panel 3 to which the ventilation fan body 1 is fixed is provided.
Is fixed to the foundation 7 under the floor.

FIG. 2 shows an outer wall 14 and an underfloor ventilation hole (note that the underfloor ventilation hole means a ventilation hole provided on a foundation of a building, for example, a cloth foundation, and a hole provided exclusively for a ventilation fan below the floor of the building. (Hereinafter, this is generally referred to as an underfloor ventilation hole.) In a case where the space between the ventilation fans 6 is small, the ventilation fan main body 1 is moved to and fixed to the upper part of the front panel 3 and is installed.

The ventilation fan body 1 is screwed above the front panel 3 through an elongated hole 10 for fixing the body 1 to the front panel 3.

(If a large number of cuts 12 are provided in the lateral direction of the shielding plate 11 as shown in the illustrated embodiment, an extra upper end piece 11a protruding from the upper end face and the lower end face of the front panel 3 is cut off. In addition, the work of cutting off the lower end piece 11b can be easily performed along the cut 12. When there is no cut 12, even after cutting off the upper end piece 11a and the lower end piece 11b, the shielding work can be performed. There is a case in which an extra uncut portion still exists on the side of the plate 11, and in such a case, the appearance is poor, and it is necessary to cut the extra uncut portion again. In this way, according to the present invention, when the underfloor ventilation fan is installed and installed, the conventional type structure shown in FIG. 4 is used. The use of the ventilation fan main body fixing panel 2 is eliminated as compared with that of the first embodiment, so that the number of parts to be used is reduced, and the installation of the ventilation fan main body 1 and the ventilation fan main body fixing panel 2 shown in FIG. This eliminates the work of sandwiching between the ventilator 3 and the ventilation fan main body fixing panel 2, thereby reducing the number of assembling steps and simplifying the work and saving labor.
