Description

[Detailed description of the invention] This invention relates to a ceiling-embedded ventilation fan, which has a structure that allows the louver mounting bracket to be installed extremely easily, improves assembly workability, and greatly reduces the number of parts during manufacturing. The purpose of the present invention is to provide a ceiling-embedded ventilation fan that reduces parts costs.

As shown in FIGS. 1 to 3, a conventional ceiling-embedded ventilation fan has a spot nut 102 welded to the inside of a main body 101, and a hole 10 for inserting a louver retaining spring 103.
The mounting bracket 105 provided with 4 is screwed onto the spot nut 102 with the screw 106 and fixed.
I was using it. Then, the louver fixing spring 103 fixed inside the louver 107 is inserted into the insertion hole 104, and the louver 107 is inserted into the main body 10.
It was fixed at 1. Therefore, first, a step of welding the spot nut 102 to the inner surface of the main body 101 was required, and the cost of the parts was also required.
Next, since the mounting bracket 105 is attached with screws 106, the extremely difficult work of screwing it to the inner surface of the main body 101 is required, and the cost of parts is also required.

The present invention is intended to eliminate the above-mentioned conventional drawbacks, and embodiments thereof will be described below with reference to FIGS. 4 to 8.

In the figure, 1 is a main body fixing a motor mounting leg 3 to which a motor 2 is attached, 4 is a blade rotated by the motor and used to ventilate the ventilation passage 5, 6 is an orifice for guiding air to the blade 4, Reference numeral 7 denotes a louver with a louver retaining spring 8 provided inside, 9 a louver retainer having a hole 10 for inserting the louver retainer spring 8, and 11 a cut-and-raised louver retainer provided on the flange 12 of the main body 1. This is for fixing 9. Reference numeral 13 denotes a protrusion provided on the louver stopper 9 for fitting and fixing into the hole 14 provided in the flange 12 of the main body 1. 15 is a wooden frame for mounting provided on the ceiling.

In the above configuration, when the blade 4 is rotated by the motor 2, indoor air sucked in from the louver 7 is discharged outside through the ventilation path 5.

Next, to attach the louver stopper 9 to the main body 1, attach the louver stopper 9 to the main body 1 from the inside of the main body 1.
The protrusion 13 provided on the louver stopper 9 is inserted inside the raised cut 11 provided on the flange 12 of the
is fitted into the hole 14 provided in the flange 12 and fixed. Furthermore, since the cross-sectional shape of the protrusion 13 is as shown in FIG. 8, it does not come off easily. Therefore, the louver stopper 9
It can be installed extremely easily without welding extra parts or tightening screws. Then, the louver fixing spring 8 can be inserted into the insertion hole 10 provided in the louver fixing fitting 9 attached as described above to fix the louver 7 to the main body 1.

As described above, according to the present invention, it is extremely easy to install the louver stopper, eliminating the need for welding extra parts or tightening screws in difficult conditions, greatly improving assembly work efficiency, and improving manufacturing efficiency. This has the effect of greatly reducing the number of parts at the time and reducing parts costs.
