Description

[Detailed Description of the Invention] Technical Field of the Invention The present invention relates to a ventilation fan having a decorative frame attached to the ventilation fan body installed on a room wall.

Technical background of the invention Conventionally, for example, in a ceiling ventilation fan, a ventilation fan body consisting of a blower device housed in an outer box is installed on the ceiling of a room wall, and a ventilation fan body is installed on the ceiling of a room wall to cover the bottom surface of the ventilation fan body. For example, there is a structure in which a decorative frame made of plastic in the form of a substantially rectangular plate is attached by an appropriate attachment means.

Problems with the Background Art In the above-mentioned conventional products, deformation such as warpage occurs in the decorative frame over time due to the attachment force (tensile force) of the attachment means etc. acting on the decorative frame. A gap may occur between the decorative frame and the ceiling of the room wall, which not only looks bad, but also causes vibrations in the decorative frame during ventilation operation, causing abnormal noise. I had a problem with this.

OBJECT OF THE INVENTION Accordingly, an object of the present invention is to provide a ventilation fan that can prevent the decorative frame from warping or other deformation, thereby solving the above-mentioned problems, and further improving the operability of attaching and detaching the decorative frame.

Summary of the invention The present invention is characterized in that a thick-walled piece that protrudes outward from the peripheral edge of the decorative frame and is long in the circumferential direction and can be handled, improves strength. It is.

Embodiment of the invention Hereinafter, a first embodiment of the invention applied to a ceiling ventilation fan will be described with reference to FIGS. 1 to 4. First, in FIG. 1, reference numeral 1 denotes a ventilation fan body, which is constructed by housing a blower device 5 consisting of a centrifugal fan 3 and a drive motor 4 in an outer box 2. The ventilation fan main body 1 is installed on the ceiling 6 of the room wall so that the suction port 1a of the ventilation fan main body 1 faces the indoor room 7. In addition, 8 is a connecting duct, which has a shutter 8a, and the connecting duct 8
The outlet 1b on the side of the ventilation fan body 1 and the exhaust pipe 9
are connected. 10 is a decorative frame made of plastic, for example, as shown in Fig. 2.
A frame part 12 is formed in an upright shape on the peripheral edge of the main plate part 11 which has a substantially rectangular shape, and a large number of slit-shaped ventilation holes 13 are formed in the main plate part 11, and the lower end of the frame part 12 which is the peripheral part As shown in FIG. 3, a thick piece portion 14 is integrally formed with the thick piece portion 1.
Reference numeral 4 denotes a piece that protrudes outward and is elongated in the circumferential direction and can be handled, and in this case, is formed over the entire circumference. In this case, the thick piece portion 14 is set to be larger than the thickness of the main plate portion 11 of the decorative frame 10. The decorative frame 10 is removably attached to the ventilation fan body 1 via attachment devices 15, 15 as shown in FIGS. 1 and 4 so as to cover the lower surface of the ventilation fan body 1. The mounting device 15 is composed of a hook 16 made of a spring material provided on the outer box 2, and a hook 17 provided on the decorative frame 10 and hooked to the hook 16, and Kakeiko 1
Reference numeral 6 has a spring force so that it is always expanded, and as a result, the hook 17 and thus the decorative frame 10 are always pulled upward and held.

Now, according to the present embodiment configured as described above, the thick piece part 14 projecting outward and having an elongated shape in the circumferential direction is integrally formed on the frame part 12 (peripheral part) of the decorative frame 10. Reinforcement of the frame portion 12 and, in turn, the decorative frame 10
The decorative frame 10 can be strengthened, especially against deformation due to warping, etc., thereby preventing the decorative frame 10 from warping.
As a result, the decorative frame 10 can always be kept in a state where there is no gap between the decorative frame 10 and the ceiling 6, and it is possible to prevent vibrations during ventilation operation and prevent abnormal noises from occurring due to this.
Appearance may also be improved. Further, according to this embodiment, since the thick piece part 14 is made to protrude outward and can be handled, the thick piece part 14 can be used as a handle when installing the decorative frame 10, and the installation operation and removal of the decorative frame 10 can be carried out easily. It can make the operation easier.

In the first embodiment, the thick piece portion 14 is connected to the frame portion 1.
Although the thick piece portion 14 is provided at the lower end portion of the frame portion 12 (peripheral portion) over its entire circumference, the formation position of the thick piece portion 14 is not limited to the lower end portion of the frame portion 12. As shown in FIG. 5, the thick piece 14 may be located in the middle of the frame 12 in the vertical direction, and the thick piece 14 does not extend over the entire circumference of the frame 12, for example, as shown in FIGS. As shown in FIG. 8, it may be partially provided at the four corners of the frame 12, at the middle of each side of the frame 12, and at the lower part of the four corners of the frame 12. It may be formed so that it protrudes outward and has a long shape in the circumferential direction so that it can be handled.

Next, FIG. 9 shows a sixth embodiment of the present invention, which differs from the fifth embodiment in that the display label 18 is attached to the frame 12 of the decorative frame 10. Unlike FIG. 8), in this embodiment, the thick piece 14 can be used as a support for the hand/arm or as a guide for attaching the display label 18.

FIG. 10 shows a seventh embodiment of the present invention, which is different from the sixth embodiment in that a recess 19 for pasting the display label 18 is formed in a part of the thick piece 14. Although different from (FIG. 9), the same effects as the sixth embodiment can be obtained.

In addition, the present invention is not limited to the embodiments described above and shown in the drawings; for example, it is not limited to ceiling fans, but can be widely applied to ventilation fans in general equipped with a decorative frame, and can be applied in various ways without departing from the gist. Can be modified and implemented.

Effects of the invention As explained above, the present invention can prevent deformation such as warpage of the decorative frame, and therefore eliminates the creation of a gap between the decorative frame and the room wall, and eliminates the vibration and It is possible to eliminate the generation of abnormal noise, improve the appearance, and improve the operability of attaching and detaching the decorative frame. It is possible to provide a ventilation fan that has effects such as making work easier.
