DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ventilation fan mounting member mainly installed on a wall of a room such as a home or office.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 2, this type of ventilation fan mounting member has a screw portion 103 on an inner periphery of a pipe which can be screwed into an opening 102 provided in a chamber wall 101, and is provided at an end portion. A large-diameter pipe 105 having a flange portion 104 having a diameter larger than the opening inner diameter, and a small-diameter pipe 107 having the screw portion 103 on the outer periphery of the pipe and having a flange portion 106 similar to the flange portion 104 at an end portion. Is screwed so as to sandwich the chamber wall 101, and an electric motor 109 having a blade 108 fixed to the inside of a cylindrical main body having an outer diameter smaller than the inner diameter of the pipe 107 is disposed in the opening of one small-diameter pipe 107. A ventilation fan main body 111 having a mounting spring 110 on the outer periphery of the main body is fixed inside the small-diameter pipe 107 by the elastic force of the mounting spring 110, while the large-diameter pipe 10 is fixed.
5, a vent cap 112 was attached to the opening, and a decorative grill 113 was attached to the ventilation fan main body 111.

[0003]

In such a conventional ventilation fan mounting member, an opening is provided in a partition wall, a ventilation device is arranged, and when ventilation is performed between rooms, a ventilation fan main body 111 is installed. In the opening of the room on the side of the large-diameter pipe 105, there is a decorative grill 1 provided on the ventilation fan body 111.
There is a problem that the beauty of the room is spoiled because a makeup grille of the same shape as 13 cannot be attached.

[0004] The present invention solves the above-mentioned problems. When a ventilation device is arranged on a room partition wall for ventilation between rooms, a makeup grill can be arranged in both rooms, and the aesthetic appearance of the room can be improved. An object of the present invention is to provide a ventilation fan mounting member that can prevent damage.

[0005]

In order to achieve the above object, a ventilation fan mounting member of the present invention is provided at an opening provided in a room partition wall and has a threaded portion which can be screwed together with an inner periphery of a pipe. A large-diameter pipe, a small-diameter pipe having the screw portion on the outer periphery of the pipe, a flange having a diameter larger than the inner diameter of the opening provided on the end face of the large-diameter pipe and the small-diameter pipe, and a flange of the small-diameter pipe. A ventilating fan body having a larger-diameter main body-side flange portion, mounted in the small-diameter pipe, a decorative grille mounted on the outer periphery of the main body-side flange portion of the ventilating fan main body, and having an L-shaped annular cross section; A mounting part having the same diameter as the main body side flange part and inserted into the outer circumference of the large diameter pipe is provided, and a decorative grille having the same shape as the decorative grille is mounted on the outer circumference of the mounting part.

[0006]

According to the present invention, a makeup grille having the same shape as a makeup grill provided on a ventilation fan main body attached to a small-diameter pipe attached to a small-diameter pipe attached to a ventilation pipe main body is also attached to a large-diameter pipe side. This makes it possible to prevent the appearance of the room from being spoiled because the makeup grills are provided in both rooms.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIG.

As shown in the drawing, a large-diameter pipe 69 having a screw portion 67 provided on an opening 66 provided in a room partition wall 74 and capable of screwing with each other is provided on an inner periphery of the pipe.
7, a large-diameter pipe 69, a flange portion 68 having a larger diameter than an opening 66 provided at an end face of the small-diameter pipe 75, and a main body side having a larger diameter than the flange portion 68 of the small-diameter pipe 75. A ventilation fan main body 70 having a flange portion 76 and mounted in a small-diameter pipe 75 by a mounting spring 77; a decorative grille 71 mounted on an outer periphery of a main body side flange portion 76 of the ventilation fan main body 70; A large-diameter pipe 69 which is annular and has the same shape as the outer diameter of the main body side flange portion 76.
And a fitting grille 72 having the same shape as the decorative grille 71 is mounted on the outer circumference of the fitting grille 72.

In the above configuration, when the ventilation fan main body 70 is provided on the indoor partition wall 74 to perform ventilation between the rooms, the fitting 72 is inserted into the outer periphery of the large-diameter pipe 69 and then the indoor partition wall 74 is removed. The large-diameter pipe 69 and the small-diameter pipe 75 are screwed via a screw portion 67 so as to sandwich the small-diameter pipe 75, and the flange 68 on the small-diameter pipe 75 is brought into contact with one wall surface of the indoor partition wall 74. Flange part 68
Is brought into contact with the wall surface of the indoor partition wall 74 via the mounting part 72.

The mounting spring 7 is mounted in the small-diameter pipe 75.
7, a ventilation grill 71 is mounted on the outer periphery of a main body side flange portion 76 provided on the ventilation fan main body 70, and a decoration grill 73 is mounted on an outer periphery of a mounting component 72 provided on the large diameter pipe 69 side. A makeup grill 71 and a makeup grill 72 are provided in both installation rooms.

As described above, according to the ventilation fan mounting member of the present invention, the main body side flange portion 76 provided on the ventilation fan main body 70 is provided.
And the outer diameter of the mounting part 72 inserted and provided in the large-diameter pipe 69 is made the same diameter, so that the decorative grill 73 having the same shape as the decorative grill 71 mounted on the main body side flange portion 76 is connected to the large-diameter pipe. It can also be installed on the 69 side, and a makeup grill 71 and a makeup grill 73 are provided in both rooms.
This can prevent the aesthetics of the room from being impaired,
The makeup grills 71 and 73 can be shared, and the number of parts can be prevented from increasing.

[0012]

As is apparent from the above embodiments, according to the present invention, a large-diameter pipe having a thread portion which is disposed in an opening provided in an indoor partition wall and which can be screwed to each other on the inner periphery of the pipe. A small-diameter pipe having the screw portion on the outer periphery of the pipe; a large-diameter pipe and a flange having a diameter larger than the inner diameter of the opening provided on an end face of the small-diameter pipe; and a main body having a larger diameter than the flange of the small-diameter pipe. It has a side flange,
A ventilation fan main body mounted in the small-diameter pipe, a decorative grill mounted on an outer periphery of a main body-side flange portion of the ventilation fan main body, and an L-shaped annular section having the same diameter as the main body-side flange portion; And a decorative grille of the same shape as the decorative grille is mounted on the outer periphery of the mounting part. It is possible to provide a ventilation fan mounting member which can be disposed and does not impair the aesthetic appearance of the room.
