BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ventilating fan mounting apparatus in which a cylindrical ventilation port penetrating inside and outside a room is opened mainly on a wall surface of a home or office or the like, and a ventilation fan is mounted using the ventilation port.

[0002]

2. Description of the Related Art Conventionally, when installing a ventilation fan using this type of ventilation fan mounting device, as shown in FIG. 8, in the case of a new construction, first, a pillar 101 or the like, which is a structural body, is assembled by a contractor. In the meantime, the electric contractor delivering the ventilation equipment fixed the pipe duct 103 cut in advance according to the wall thickness dimension of the room wall 102 to be constructed later to the pillar 101 at a predetermined position using the support member 104 or the like. I do.
Next, a contractor attaches an outer wall 106 having an opening 105 serving as a through-hole of the pipe duct 103, and performs caulking work for preventing rainwater intrusion. Next, when an electric contractor performs indoor wiring work such as lighting and a general outlet (not shown), a power supply wire 107 is laid inside the room wall 102. Next, the contractor determines that the opening 105 serving as a through-hole of the pipe duct 103 and the power supply wire 107
Wall 1 with a small hole 109 that draws air into the room 108 side
10 and the power supply wire 107 is inserted into the small hole 109.
To the interior 108 side to finish the interior. After this, the electrician contracts the power line 107 to the ventilation fan 111.
And the ventilation fan 111 is inserted into and fixed to the pipe duct 103 from the room 108 side, and the vent cap 11 is connected to the outdoor 113 side of the pipe duct 103.
4 and so on, and coking work to prevent intrusion of rainwater on the outdoor 113 side was also performed to complete the installation work.

In the case of an existing building, an opening 105 for embedding a pipe duct 103 in a room wall 102 and a small hole 109 for drawing a power supply wire 107 into the room 108 are opened.
The pipe duct 103 cut to fit the wall thickness of the room wall 102 is embedded in the opening 105, and the caulking work is performed to fix the pipe duct 103 and prevent rainwater intrusion.
Pull in to the 8 side. After this, the power line 107 is connected to the ventilation fan 1
11 and the ventilation fan 111 is inserted into the pipe duct 103 from the room 108 side and fixed, and a vent cap 114 and the like are attached to the outdoor 113 side of the pipe duct 103 to prevent rainwater from entering the outdoor 113 side. In addition, coking work was also performed to complete the installation work.

In that case, the electric contractor groped and found the pipe duct 10
The position of No. 3 had to be found, and the opening 105 serving as a through-hole of the pipe duct 103 had to be opened. Also,
A small hole 109 is separately formed to connect the power supply wire 107 to the room 108.
There was also a problem that it was necessary to pull in to the side, and a very wasteful time was taken.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and provides a ventilation fan mounting device that allows a contractor to always open an opening serving as a through hole of a duct in an inner wall when attaching the inner wall. As a first object.

Another object of the present invention is to eliminate the necessity of separately forming a small hole for drawing a power supply wire into a room.

[0007] A third object is to make it possible to adjust the length of the duct with the inner wall attached. Also,
A fourth object is to make it possible to easily connect a power supply in a power supply connection device with an inner wall attached.

A fifth object is to eliminate the work of cutting the duct. A sixth object is to enable the outdoor end of the duct to be securely fixed to the outer wall.

A seventh object is to ensure that the ventilation device can be installed and fixed even in a place where the room wall is constructed of a brittle material such as gypsum board.
