る。[Detailed description of the invention] Industrial field of use In recent years, ceiling-embedded ventilation fans that can provide high static pressure have been increasingly used as a means to ventilate rooms. The present invention relates to the structure of a ventilation fan body for attaching the louver of such a ceiling-embedded ventilation fan.

た。Structure of conventional example and its problems As shown in FIGS. 1 and 2, a conventional ceiling-mounted ventilation fan has a louver mounting bracket 102 fixed to the inside of a ventilation fan body 101 by spot welding. In this case, since the louver retaining spring 103 constantly applies force in the downward direction (arrow a), there is a possibility that the louver 104 may fall due to irregularities in spot welding or the like. In addition, as shown in FIGS. 3 to 5, a louver mounting bracket 202 is attached to the inside of the ventilation fan body 201 using screws 20.
3, the tips of the screws 203 would protrude outside the ventilation fan main body 201, which would be dangerous and would get in the way when the main body was installed. In addition, since the ventilation fan body 201 is screwed to the inside thereof, it is difficult to manufacture the ventilation fan body 201.

ものである。DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 6 to 8. In the figure, 1 is the ventilation fan body, 2
3 is a louver provided with a spring 4 for fixing the louver; 5 is an L-shaped cut-and-raised part 2 that can be fixed on one side after insertion. A louver mounting bracket is provided with an insertion hole 7 for a louver fixing spring 4 on the other side of the hole 6, and 8 is a main frame for mounting the ventilation fan body 1 on the ceiling 9. The hole 6 is a combination of a hole b10 slightly larger than the cut and raised portion 2 and a hole c11 slightly larger than the board thickness of the cut and raised portion 2.

る。 In the above configuration, the louver mounting bracket 5 is fixed by inserting the cut and raised portion 2 into the larger hole c10 of the louver mounting bracket 5 as shown in FIG. 9, and then lowering the louver mounting bracket 5 as shown in FIG. Then, as shown in FIG. 11, move the louver mounting bracket 5 so that the cut and raised portion 2 is located in the smaller hole c11 of the louver mounting bracket 5. The louver fixing spring 4 is inserted into the insertion hole 7 provided in the louver mounting bracket 5 attached as described above to fix the louver 3 to the ventilation fan main body 1.
