Description

[Detailed description of the invention] This invention relates to a ceiling-embedded ventilation fan, and particularly to a ventilation fan with improved installation workability.

Fig. 1 is a partially omitted vertical sectional view of a ceiling-embedded ventilation fan. In the figure, 1 is the ceiling, 2 is the edge of the ceiling, 3 is the ventilation fan body that is installed in the edge of the ceiling, and 4 5 is a blade provided on the ventilation fan main body, 5 is an electric motor that drives the blade, and 6 is a grill that covers the opening surface of the ventilation fan main body 3.

FIG. 2 is an exploded perspective view of a grill in a conventional ventilation fan. Reference numeral 7 denotes a pair of spring support pieces that are integrally molded on opposing parts inside the grill 6, into which a ring part 8a of a spring 8 is inserted. and a screw 9 in the mounting hole 7a provided opposite to this.
is designed to be inserted and secured with nut 10. The spring 8 is configured such that a locking portion 8b extends from a ring portion 8a to both sides and is locked to a holding portion 12 provided inside the ventilation fan main body 3.

In the conventional ceiling-embedded ventilation fan configured as described above, the ring portion 8a of the spring 8 is inserted between the spring support pieces 7 of the grille 6, and the spring 9 is inserted into the mounting hole 7a.
The grill 6 is attached by inserting it through the ring portion 8a and fixing it with a nut 10, and holding the spring 8 by locking the locking portion 8b of the spring 8 with the holding portion 12 of the ventilation fan main body 3.
Therefore, when inserting the spring 9 and attaching the spring 8, it is necessary to hold the nut 10 with one hand and hold a screwdriver with the other hand to tighten the screw, which has the drawback of poor workability.

This invention was made in order to eliminate the drawbacks of the conventional ones as described above, and it has a stopper at one end, and a stopper is formed at the other end to be inserted into the mounting hole of the spring support piece and the ring part of the spring. The purpose of the present invention is to provide a ceiling-embedded ventilation fan with excellent spring mounting workability by mounting the spring on the grill with a mounting member having a caulking part.

An embodiment of this invention will be described below with reference to the drawings. FIG. 3 is an exploded perspective view of a grill in an embodiment of the invention, FIG. 4 is a front view of a spring support piece, FIG. 5 is a perspective view of a mounting member, and FIG. 6 is a sectional view of main parts. The same reference numerals as in FIGS. 1 and 2 indicate the same or corresponding parts. Reference numeral 11 denotes a mounting member, which has a bent stopper 11b at one end of a bent piece 11a having a substantially U-shaped cross section, and a caulking portion 1 formed at the other end by caulking (bending) to form a stopper.
1c. The mounting hole 7b of the spring support piece 7 is formed in a substantially semicircular shape corresponding to the bent piece 11a of the mounting member 11. The other configurations are the same as those in FIGS. 1 and 2.

In the ceiling-embedded ventilation fan configured as above, the ring portion 8a of the spring 8 is inserted between the spring support pieces 7, and the mounting member 11 is inserted from the caulked portion 11c side into the mounting hole 7b and the ring portion 8a. after,
As shown in FIG. 6, the caulked portion 11c is caulked to form a stopper, and the spring 8 is attached to the grille 6. Other operations are similar to those in FIGS. 1 and 2.

In the ceiling-embedded ventilation fan described above, the mounting hole 7b is semicircular and the mounting member 11 is approximately U-shaped, so the mounting member 11 has directionality, and the state in which the mounting member 11 is inserted into the mounting hole 7b is The caulking can be done by simply bending the caulked portion 11c in one direction, making the installation work easy. Further, since the spring 8 can be mounted with the ring portion 8a in contact with the U-shaped bottom side of the mounting member 11, damage to the ring portion 8a is eliminated.

As described above, according to this invention, the spring is grilled by the mounting member having a stopper at one end and a caulking part for forming the stopper at the other end which is inserted into the mounting hole of the spring support piece and the ring part of the spring. Since the grille is attached to the ventilation fan body, the spring can be easily attached and workability is improved.
