Description

[Technical field]

[0001] The present invention relates to a ventilation fan mounting fixture used for mounting a ventilation fan. [Background technology]

[0002] Conventionally, there has been known a ventilator having a cylindrical frame that rotatably supports the fan and a flange provided on the frame, in which the frame is inserted into a ventilation hole formed in a mounting surface and the fan is mounted to the mounting surface via the flange (see, for example, Patent Document 1). This type of ventilator exhausts indoor air to the outside by rotating the fan. The invention described in Patent Document 1 places an airtight material between the mounting surface, such as a wall or ceiling, and the flange of the ventilation fan, thereby suppressing outside air from flowing in through the gap between the mounting surface and the flange, and preventing dirt around the ventilation fan that occurs on the mounting surface due to this inflow of outside air. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2010-014393 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, dirt around such ventilation fans is caused not only by outside air flowing in through the gap between the mounting surface and the flange, but also by indoor dust flowing along the mounting surface along with the indoor air being exhausted to the outside, so there is a problem in that simply increasing the airtightness of the gap between the mounting surface and the flange cannot adequately prevent dirt around the ventilation fan.

[0005] An object of the present invention is to provide a mounting fixture for a ventilation fan that is used to mount a ventilation fan and can reliably prevent the area around the ventilation fan from getting dirty. [Means for solving the problem]

[0006] The mounting fixture for a ventilation fan of the present invention has a cylindrical frame body that rotatably supports a fan, and a flange portion provided on the frame body, and has a mounting surface. A wall or ceiling that is The frame is inserted into the ventilation hole formed in the mounting surface and the flange is attached to the mounting surface. By screw The mounting fixture for a ventilation fan used for a ventilation fan to be mounted has a hole for inserting a frame body, is disposed between the mounting surface and the flange, and includes a plate-like body that protrudes outward beyond the flange, and the plate-like body is provided with a peripheral edge Integral The mounting surface is formed with a raised portion that rises toward the opposite side of the mounting surface.

[0007] According to this configuration, the mounting fixture for a ventilation fan is disposed between the mounting surface and the flange and includes a plate-like body that protrudes outward beyond the flange, so that the airtightness of the gap between the mounting surface and the flange can be improved. Integral The ventilation fan mounting fixture of the present invention is formed with a wall and a rising portion that rises toward the opposite side of the mounting surface, so that the rising portion can prevent indoor dust from flowing along the mounting surface together with the indoor air that is discharged to the outside. Therefore, the ventilation fan mounting fixture of the present invention can reliably prevent the surroundings of the ventilation fan from becoming dirty.

[0008] In the present invention, the standing portion is preferably formed around the entire peripheral edge of the plate-like body.

[0009] With this configuration, the raised portion is formed around the entire peripheral edge of the plate-shaped body, thereby preventing dust from inside the room from flowing along the mounting surface all around the periphery of the ventilation fan, and more reliably preventing dirt from building up around the ventilation fan.

[0010] In the present invention, it is preferable that the plate-like body is provided with a screw hole for fastening the plate-like body and the flange together by being formed at a position corresponding to a screw hole formed in the flange for attaching the flange of the ventilation fan to the mounting surface.

[0011] With this configuration, the plate-like body is formed at a position corresponding to a screw hole formed in the flange for attaching the flange of the ventilation fan to the mounting surface, and is provided with a co-tightening screw hole for fastening the plate-like body and the flange together, so that the ventilation fan mounting fixture can be easily attached to the mounting surface by utilizing the screw used for the screw hole formed in the flange.

[0012] In the present invention, the plate-like body preferably has a protruding portion that protrudes outward beyond the standing portion.

[0013] Here, when the ventilation fan mounting fixture is attached along the corner of a building that is formed by a mounting surface and a wall surface perpendicular to the mounting surface, the standing part becomes one with the wall surface, and therefore the standing part cannot prevent indoor dust from flowing along the wall surface along with the indoor air that is discharged to the outside, resulting in the problem that it is not possible to reliably prevent dirt from getting around the ventilation fan. According to the present invention, the plate-like body has a protruding portion that protrudes outward beyond the standing portion, so that a gap can be formed between the standing portion and the wall surface perpendicular to the mounting surface. Therefore, the standing portion can reliably prevent indoor dust from flowing along the wall surface together with the indoor air discharged to the outside, and can reliably prevent the periphery of the ventilator from becoming dirty.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0015] [First embodiment] A first embodiment of the present invention will now be described with reference to the drawings. FIG. 1 is a perspective view showing a ventilation fan mounting fixture according to a first embodiment of the present invention. FIG. 2 is a front view and a side view showing the ventilation fan mounting fixture. Specifically, FIG. 2(A) is a front view showing the ventilation fan mounting fixture, and FIG. 2(B) is a side view showing the ventilation fan mounting fixture. In FIG. 1 and FIG. 2, the upward vertical direction is defined as the +Z axis direction, and two axes perpendicular to the Z axis are defined as the X and Y axes. The same applies to the following drawings.

[0016] As shown in Figures 1 and 2, the ventilation fan mounting fixture 1 comprises a rectangular plate-like body 2. The plate-like body 2 has a rectangular hole 21 at approximately the center, four screw holes 22 formed at each of the four corners, and eight co-fastening screw holes 23 formed along the four sides of the hole 21. The plate-like body 2 is provided with four upright portions 3 formed along the periphery of the plate-like body 2 and rising from each side of the plate-like body 2 toward the +X-axis direction, and four L-shaped reinforcing metal fittings 4 attached to the connection sites of the upright portions 3. Here, each upright portion 3 is formed around the entire periphery of the plate-like body 2. In this embodiment, the plate-like body 2 is formed in a rectangular shape, but may be formed in, for example, a circular shape or in another shape.

[0017] Fig. 3 is a cross-sectional view of a main part showing a state in which the ventilation fan is attached to a mounting surface via the ventilation fan mounting fixture, and Fig. 4 is a front view showing a state in which the ventilation fan is attached to a mounting surface via the ventilation fan mounting fixture. 3 and 4, ventilation fan 10 has fan 101, a cylindrical frame 102 that rotatably supports fan 101, and a flange 103 provided on frame 102. Ventilation fan 10 also has a cover 104 that covers fan 101, and a shutter 105 that closes when fan 101 is stopped to prevent outside air from entering. This ventilation fan 10 has a frame 102 inserted into a ventilation opening H formed in a mounting surface S such as a wall or ceiling, and is attached to the mounting surface S via a flange 103. The ventilation fan 10 also includes a hood 106 that prevents rainwater from entering the ventilation opening H, and a power cable 107 for supplying power to the ventilation fan 10.

[0018] The mounting fixture 1 for a ventilation fan is constructed by inserting the frame 102 of the ventilation fan 10 into the hole 21 of the plate-like body 2, inserting the frame 102 into the ventilation opening H, and fastening the flange 103 of the ventilation fan 10 and the plate-like body 2 together to the mounting surface S with a screw SC1 via the fastening screw hole 23. The ventilation fan 10 can be mounted on the mounting surface S by fixing the plate-like body 2 to the mounting surface S with a screw SC2 via the screw hole 22. Here, the plate-like body 2 is disposed between the mounting surface S and the flange portion 103, and protrudes outward beyond the flange portion 103. The standing portion 3 is formed on the periphery of the plate-like body 2, and stands up toward the opposite side of the mounting surface S. The co-tightening screw hole 23 is formed at a position corresponding to a screw hole formed in the flange portion 103 for mounting the flange portion 103 of the ventilation fan 10 to the mounting surface S.

[0019] In this embodiment, the hole 21 in the plate-like body 2 has the same cross-sectional shape as the frame body 102 but is slightly larger than the cross-sectional shape of the frame body 102. However, the hole 21 may have any cross-sectional shape as long as the frame body 102 can be inserted therein. In addition, in this embodiment, the flange portion 103 of the ventilation fan 10 and the plate-shaped body 2 are fastened together to the mounting surface S with a screw SC1 via the fastening screw hole 23, but for example, if a material that can be penetrated by a screw, such as wood, resin or paper, is used as the mounting fixture for the ventilation fan, the plate-shaped body does not need to be provided with a fastening screw hole. Furthermore, in this embodiment, the plate-like body 2 has the screw holes 22, but for example, if the plate-like body 2 can be sufficiently supported by the screws SC1 alone, the plate-like body 2 does not need to have the screw holes 22.

[0020] According to this embodiment, the following actions and effects can be achieved. (1) The ventilation fan mounting fixture 1 is disposed between the mounting surface S and the flange 103 and includes a plate-like body 2 that projects outward beyond the flange 103, thereby improving the airtightness of the gap between the mounting surface S and the flange 103. Furthermore, the plate-like body 2 is formed on the periphery of the plate-like body 2 and includes an upright portion 3 that stands toward the opposite side of the mounting surface S, thereby preventing indoor dust from flowing along the mounting surface S together with the indoor air that is discharged to the outside. Therefore, the ventilation fan mounting fixture 1 can reliably prevent the surroundings of the ventilation fan 10 from becoming dirty.

[0021] (2) Since the raised portion 3 is formed around the entire peripheral edge of the plate-like body 2, it is possible to prevent dust in the room from flowing along the mounting surface S around the entire periphery of the ventilation fan 10, thereby more reliably preventing dirt from forming around the ventilation fan 10. (3) The plate-like body 2 is formed at a position corresponding to a screw hole formed in the flange portion 103 for attaching the flange portion 103 of the ventilation fan 10 to the mounting surface S, and is provided with a co-tightening screw hole 23 for fastening the plate-like body 2 and the flange portion 103 together. Therefore, the ventilation fan mounting fixture 1 can be easily attached to the mounting surface S by utilizing the screw SC1 used for the screw hole formed in the flange portion 103.

[0022] Second Embodiment A second embodiment of the present invention will now be described with reference to the drawings. In the following description, parts that have already been described will be given the same reference numerals and their description will be omitted.

[0023] Fig. 5 is a perspective view showing a ventilation fan mounting fixture according to a second embodiment of the present invention. Fig. 6 is a front view and a side view showing the ventilation fan mounting fixture. Specifically, Fig. 6(A) is a front view showing the ventilation fan mounting fixture, and Fig. 6(B) is a side view showing the ventilation fan mounting fixture.

[0024] As shown in Figs. 5 and 6, the ventilation fan mounting fixture 1A includes a plate-like body 2A formed in a rectangular shape. In addition, the plate-like body 2A, like the first embodiment, has four standing portions 3 and four L-shaped reinforcing brackets 4, and also has protrusions 5A provided at two locations on each standing portion 3 and protruding outward beyond the standing portions 3.

[0025] FIG. 7 is a cross-sectional view of a main part showing a state in which the ventilation fan is attached to a mounting surface via the ventilation fan mounting fixture. As shown in FIG. 7, the ventilation fan 10 has a frame 102 inserted into a ventilation opening H formed in a mounting surface S such as a wall, and is attached to the mounting surface S via a flange portion 103.

[0026] The mounting fixture 1A for a ventilation fan is constructed by inserting the frame 102 of the ventilation fan 10 into the hole 21 of the plate-like body 2A, inserting the frame 102 into the ventilation opening H, and fastening the flange 103 of the ventilation fan 10 and the plate-like body 2A together to the mounting surface S with a screw SC1 via the fastening screw hole 23. The ventilation fan 10 can be mounted on the mounting surface S by fixing the plate-like body 2 to the mounting surface S with a screw SC2 via the screw hole 22. Here, the plate-like body 2A has a protruding portion 5A that protrudes outward beyond the standing portion 3, so that a gap can be formed between the ceiling L, which is a wall surface perpendicular to the mounting surface S, and the standing portion 3 at the protruding portion 5A.

[0027] In this embodiment as well, in addition to being able to achieve the same actions and effects as the first embodiment, the following actions and effects can be achieved. (4) The plate-like body 2A has a protruding portion 5A that protrudes outward beyond the standing portion 3, so that the protruding portion 5A can form a gap between the standing portion 3 and the ceiling L, which is a wall surface perpendicular to the mounting surface S. Therefore, the standing portion 3 can reliably prevent indoor dust from flowing along the wall surface together with the indoor air discharged to the outside, and the surroundings of the exhaust fan 10 can be reliably prevented from becoming dirty.

[0028] [Modifications of the embodiment] The present invention is not limited to the above-described embodiments, and modifications and improvements within the scope of the present invention that can achieve the object of the present invention are included in the present invention. For example, in each of the above embodiments, each standing portion 3 was formed around the entire periphery of the plate-like body 2, 2A, but it does not have to be formed around the entire periphery, and may be formed only in a part of the periphery of the plate-like body 2, 2A.

[0029] In each of the above embodiments, the plate-like body 2, 2A is provided with a screw hole 23 for fastening together the plate-like body 2 and the flange 103 by being formed at a position corresponding to a screw hole formed in the flange 103 for attaching the flange 103 of the ventilation fan 10 to the mounting surface S. In contrast, the plate-like body may be attached in any manner as long as it can be disposed between the mounting surface and the flange, and may be attached to the mounting surface and the flange using an adhesive or the like, for example. [Industrial Applicability]

[0030] INDUSTRIAL APPLICABILITY As described above, the present invention can be widely applied to ventilation fan mounting fixtures used for mounting ventilation fans. [Explanation of symbols]
