Description

[Detailed description of the invention] This invention relates to an improvement of a mounting device for a ventilation fan that is mounted on a ceiling and ventilates through a duct.

Conventionally, this type of fan has a mounting frame 1 that is slightly larger than the dimension A of the ventilation fan body 2, as shown in Fig. 1.
is installed on the ceiling, the main body 2 is inserted into this mounting frame 1 from the indoor side, and the flange portion 3 provided on the main body 2 is inserted into the mounting frame 1 from the indoor side.
is brought into contact with the mounting frame 1 and fixed with screws, and the duct 5 is connected to the duct connection port 4 provided in the exhaust port of the blower (not shown) installed inside the main body 2, which can be attached and detached from the inside of the main body 2. The main body 1 is installed on the indoor side of the mounting frame 1.
A ceiling material a having an opening 6 slightly larger than the dimension B of the flange portion 3 was installed, and the opening 6 was covered with a decorative grille 7 having ventilation holes. In addition, when the ceiling strength is weak, anchor bolts 9 are lowered from the structure 8 of the building in the attic and fixed with nuts using hanging fittings 10 provided on the main body 2 to support the weight.

For ventilation fans installed in this way, the dimensions of the ventilation fan body 2 differ depending on the ventilation air volume capacity and purpose, so it is necessary to prepare the mounting frame 1 and ceiling material a with openings that match the body dimensions each time. In addition, if you change the model of the ventilation fan to be installed, you will have to re-create the mounting frame and opening in the ceiling material. had the disadvantage that the main unit could not be removed indoors after the ceiling panel was installed.

This idea was created in view of the above-mentioned drawbacks, and by attaching the ventilation fan through an auxiliary frame provided to close the gap formed between the main body and the mounting frame, the main body The object of the present invention is to provide a ventilation fan mounting device that can standardize the building structure by absorbing the size of the frame with an auxiliary frame and making the openings of the mounting frame and ceiling material constant.

Hereinafter, one embodiment of this invention will be explained according to Fig. 2. In the figure, 2 to 6, 8, 9, and a indicate the same or equivalent parts as in the conventional example, and 11 is formed with constant dimensions. The mounting frame 12 is an auxiliary frame that has an opening 13 that is slightly larger than the main body 2 and has an external dimension that is slightly smaller than the opening 6, and closes the gap formed between the main body 2 and the mounting frame 1. A mounting foot 15 is provided with an engagement hole 14 into which an anchor bolt 9 fixed to the structure 8 is engaged.
Reference numeral 16 denotes a decorative grille, which is detachably attached to the auxiliary frame 12 with an attachment knob 17.

For example, in a housing complex, etc., the structure as described above is used by attaching a mounting frame 11 formed to a predetermined size, a ceiling material a having a predetermined opening 6, and then attaching an auxiliary frame 12 to an anchor bolt 9. Engagement hole 1
4, hang it with a nut, and fix it by attaching it to the mounting frame 11 with a screw. The main body 2 is inserted into the auxiliary frame 12 fixed in this manner and fixed with screws, the duct 5 is connected to the duct connection port 4, and the decorative grille 16 is attached using the mounting knob 17, thereby completing the installation.

By installing it in this way, the two dimensions of the ventilation fan body can be adjusted by the size of the opening 13 of the auxiliary frame 12, so even if the floor plan is the same in apartment buildings, etc., the ventilation capacity of the ventilation fan can be secured by adjusting the duct length. Even when installing different models, the mounting frame 11 can be standardized by having the same dimensions, and by fixing the decorative grille 16 to the auxiliary frame 12 with the pitch of the mounting knob constant, the interior design can be unified. Not only that, even if you change the model, you only need to replace the auxiliary frame 12.
Further, since the anchor bolt 9 is fixed to the auxiliary frame 12, the main body can be easily removed to the indoor side by removing the duct connection port 4 from the inside of the main body 2 during maintenance.

As explained above, according to this invention, the ventilation fan body has an engagement hole for engaging an anchor bolt provided in the building structure behind the ceiling, and an auxiliary support having an opening in the center through which the ventilation fan body can be inserted. The frame is fixed to the anchor bolts and a mounting frame provided on the ceiling, and the ventilation fan body is inserted into the opening of the auxiliary frame, and the ventilation fan body is removably attached to the auxiliary frame. Even after the ceiling board is installed, the ventilation fan body can be easily removed from the auxiliary frame and
The size of the main frame can be absorbed by the auxiliary frame, so the openings of the mounting frame and ceiling material can be made constant, standardizing the building structure, and facilitating the design and construction of apartment complexes, etc. be.
