First, the case where the ventilation device A is installed in a stationary manner will be described. In this case, the leg portion 30 is placed downward and placed in a mounted state. The case where the ventilation device A is installed under the floor of the house will be described as an example. First, when the ventilation device A is installed under the floor of the house, as shown in FIG. Is placed directly on the ground S in a state of facing the ground S side. In this case, it may be simply placed on the ground S, but if the installation surface can be fixed by the fixing device, the fixing device is inserted into the fixing device mounting portion 34b and the fixing device is screwed onto the installation surface. The ventilation device A can be fixed to the installation surface by wearing it. As a result, the air in the underfloor space R that was blocked and retained by the cloth foundation Q and the like is agitated by the ventilation device A and circulates.

Next, a case where the ventilation device A is installed in a hanging manner will be described. In this case, the ventilator A is installed in a suspended state by turning the leg portion 30 upward and fixing the pedestal portion 34b of the leg portion 30 to the installation location (may be the installation portion). For example, in the case where the ventilation device A is installed under the floor of a house and a place where it is directly installed on the ground cannot be secured, as shown in FIG. With the pedestal portion 34b side of the portion 30 facing the beam P side, the pedestal portion 34

Further, suspend the ventilation device A by suspending the leg 30 upward and on the beam above the ceiling. It is also possible to install it in a shape.

Since the leg portion 30 of the ventilator A can be expanded and contracted, the leg portion 30 is shortened to reduce the overall height of the ventilator A when the height of the installation space is not sufficient. You can do it like this.

Further, even when the height of the installation place of the ventilation device A is not constant, the ventilation device A can be installed by making the lengths of the legs 30 different. For example, as shown in FIG. 9, when the auxiliary equipment X of the house is already installed at a place where the ventilation device A is to be arranged on the ground S, the ventilation device A
The length of the leg portion 30 at the portion where the auxiliary equipment X and the auxiliary equipment X overlap is adjusted so as to be shortened by the height of the auxiliary equipment X, and the leg portion 30 is placed on the upper surface of the auxiliary equipment X. As a result, the ventilation device A can be arranged in a desired position in an appropriate state without moving the auxiliary equipment X.

Further, as described above, the members other than the fixing portion 32b of the leg portion 30 are rotatable around the axis of the leg portion 30, so that the fixing member attaching portion 34b-2 of the pedestal portion 34b can be rotated. Can be adjusted to any position in the outer peripheral direction of the second support portion 34a. As a result, even if the mounting location of the leg portion 30 is relatively small, the mounting is possible.

For example, as shown in FIG. 10, the width of the beam P is relatively small, and the fixture attachment portion 34b-of the pedestal portion 34b-
2 cannot be attached if it is outside the axis of the second support portion 34a, the pedestal portion 34b is rotated to move the fixture attachment portion 34b-2 to the second support portion 3a.
It can be attached to the beam P so as to be inside 4a. That is, in the example shown in FIG. 10, the left and right pedestals 34b
In, the attachment to the beam P is possible by making the fixture attachment portion 34b-2 inside.

Also in the example shown in FIG.
When the ventilator A is to be installed at the position shown in Fig. 2, the right pedestal portion 34b cannot be attached to the beam P when the fixture attachment portion 34b-2 is located outside, but the pedestal portion 34b
To fix the fixture attachment portion 34b-2 to the second support portion 3
4a by making it inside the axis of FIG.
It becomes possible to attach the ventilation device A to the position shown in.

In the installed ventilator A, the motor 2
When 4 is driven, this causes the sirocco fan 22 to rotate, so that the air on the case upper surface portion 16 side of the ventilation device A is sucked and exhausted from the protective fence 14b side. In this way, the ventilation is performed by stirring the air around the ventilation device A.

As a place to install the ventilation device A of this embodiment, in reality, the ventilation device A is installed substantially at the center of the underfloor region in plan view, and further, the outside air is placed on the foundation portion located on the outer periphery of the underfloor region. It is preferable to separately attach and use a ventilation device for performing ventilation of the above (referred to as an outside ventilation device).
That is, after the air in the underfloor region is agitated by the ventilator A of this embodiment, the outside ventilator ventilates the outside air.
