2. Description of the Related Art In recent years, a ceiling-embedded ventilation fan is widely used, which exhausts polluted air in the room to the outside by using a ventilation fan installed on the ceiling in order to improve the environment of the living space. In addition, there is a growing interest in the interior property of the room, and there is a growing demand for facilitating the position adjustment of the makeup grill that covers the lower surface of the ventilation fan.

As an example of a conventional ceiling-embedded ventilation fan of this type, those shown in FIGS. 8 to 10 have been known. The configuration will be described below with reference to FIGS. 8 to 10.

As shown in the figure, it has a suction port 101 on the lower surface, a discharge port 102 on the side surface, and a blower 103 inside.
And a ventilation fan main body 107 which is inserted into and installed in the ceiling 105 through a mounting opening 106 provided in the ceiling 105 in a circular shape in which a flange 104 is formed on the lower outer periphery, and the center of the ventilation fan main body 107 on the suction port 101 side. A ring-shaped receiving portion 108 is provided to be supported by a plurality of support legs 109, and an open-ended mounting spring 110 that elastically engages with the receiving portion 108 covers a lower surface of the ventilation fan main body 107 and has a plurality of vent holes 111. Attaching part 11 to makeup grill 112 having
3 via the mounting spring 11 to the receiving portion 108
The makeup grill 112 is supported by an elastic force of 0, and the position of the makeup grill 112 is adjusted by rotating the mounting spring 110 with respect to the receiving portion 108.

[0005]

In such a conventional ceiling-embedded ventilation fan, when the direction of the ventilation port 111 provided in the decorative grill 112 is changed or the position is adjusted when the decorative grill 112 is installed. , Makeup grill 112
Since the mounting spring 110 provided on the decorative grill 112 is rotated around the receiving portion 108 by applying a turning force to the receiving grill 108, the mounting spring 110 is elastically engaged with the receiving portion 108, so that the receiving spring 108 is easily twisted. It does not rotate smoothly, it is difficult to adjust the position, and when the mounting spring 110 moves when the makeup grill 112 rotates, the mounting spring 110 may come into contact with or be caught by the support leg 109 supporting the receiving portion 108. Then, there is a problem that the position of the makeup grill 112 cannot be smoothly adjusted.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object of the present invention is to provide a ceiling-embedded ventilation fan capable of smoothly adjusting the position of a makeup grill.

[0007]

In the ceiling-embedded ventilation fan of the present invention, a circular shape having a suction port on the lower surface, a discharge port formed on the side surface, a blower provided inside, and a flange formed on the lower outer circumference is provided. The ventilation fan body that is attached to the ceiling with, and the ring-shaped receiving part that is provided in the center of the suction side of this ventilation fan body,
It is attached by a mounting spring that elastically engages with this receiving portion,
A makeup grill that covers the lower surface of the ventilation fan body is provided, and the makeup grill is rotatably provided to the attachment spring via a connecting portion.

According to the present invention, it is possible to provide a ceiling-embedded ventilation fan capable of smoothly adjusting the position of a makeup grill.

[0009]
