Description

Technical Field

[0001] The present invention relates to a mounting tool for a ventilation fan used for mounting the ventilation fan.

Background Art

[0002] Conventionally, there is known a ventilation fan having a cylindrical frame body that rotatably supports a fan and a flange portion provided on the frame body, wherein the frame body is inserted into a ventilation opening formed in an attachment surface and attached to the attachment surface via the flange portion (see, for example, Patent Document 1). Such a ventilation fan discharges indoor air to the outside by rotating the fan. The invention described in Patent Document 1 suppresses outside air flowing in from the gap between the attachment surface and the flange portion of the ventilation fan by providing an airtight material between the attachment surface such as a wall or ceiling and the flange portion of the ventilation fan, and prevents dirt around the ventilation fan generated on the attachment surface due to the inflow of this outside air.

Summary of the Invention

Problems to be Solved by the Invention

[0004] However, the dirt around such a ventilation fan is not only caused by outside air flowing in from the gap between the attachment surface and the flange portion, but also occurs because dust in the room flows along the attachment surface together with the indoor air discharged to the outside. Therefore, there is a problem that simply increasing the airtightness of the gap between the attachment surface and the flange portion cannot sufficiently prevent the dirt around the ventilation fan.

[0005] An object of the present invention is to provide a mounting tool for a ventilation fan that is used for mounting a ventilation fan and can reliably prevent dirt around the ventilation fan.

Means for Solving the Problems

[0006] The ventilation fan mounting device of the present invention is a ventilation fan mounting device used for a ventilation fan that has a cylindrical frame that rotatably supports a fan and a flange provided on the frame, and the frame is inserted into a ventilation opening formed on the mounting surface and is attached to the mounting surface via the flange, and has a hole for inserting the frame, and is positioned interposed between the mounting surface and the flange, and includes a plate-like body that protrudes outward from the flange, and the plate-like body has an upright portion formed on the periphery of the plate-like body and stands upright toward the opposite side of the mounting surface.

[0007] With this configuration, the ventilation fan mounting bracket is positioned between the mounting surface and the flange and includes a plate-like body that protrudes outward from the flange, thereby improving the airtightness of the gap between the mounting surface and the flange. Furthermore, the plate-like body has an upright portion formed on its periphery that rises toward the opposite side of the mounting surface, so the upright portion can suppress the flow of indoor dust along the mounting surface along with the indoor air being discharged to the outside. Therefore, the ventilation fan mounting bracket of the present invention can reliably prevent dirt from accumulating around the ventilation fan.

[0008] In the present invention, it is preferable that the upright portion is formed over the entire circumference of the periphery of the plate-like body.

[0009] With this configuration, since the upright portion is formed around the entire periphery of the plate-like body, it is possible to suppress the flow of indoor dust along the mounting surface around the entire periphery of the ventilation fan, thereby more reliably preventing dirt from accumulating around the ventilation fan.

[0010] In the present invention, it is preferable that the plate-like body is provided with screw holes for fastening together the plate-like body and the flange, such that the screw holes are 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 the screw holes formed in the flange portion for attaching the flange portion of the ventilation fan to the mounting surface. As a result, the plate-like body and the flange portion are equipped with screw holes for fastening them together, and the ventilation fan mounting fixture can be easily attached to the mounting surface using the screws used in the screw holes formed in the flange portion.

[0012] In the present invention, it is preferable that the plate-like body has an overhanging portion that extends outward from the upright portion.

[0013] Here, when installing a ventilation fan mounting fixture along a corner of a building, which is formed by a mounting surface and a wall surface perpendicular to this mounting surface, the upright portion becomes integrated with the wall surface. As a result, the upright portion cannot prevent indoor dust from flowing along the wall surface along with the indoor air being discharged to the outside, and thus there is a problem in that it is not possible to reliably prevent dirt from accumulating around the ventilation fan. According to the present invention, the plate-like body has an overhang that extends outward from the upright portion, so that a gap can be formed between the wall surface perpendicular to the mounting surface and the upright portion at the overhang. Therefore, the upright portion can reliably prevent indoor dust from flowing along the wall surface along with the indoor air discharged to the outside, and thus reliably prevent soiling around the ventilation fan.

Mode for Carrying Out the Invention

[0015] 〔First Embodiment〕 Hereinafter, the first embodiment of the present invention will be described based on the drawings. FIG. 1 is a perspective view showing a mounting fixture for a ventilation fan according to the first embodiment of the present invention. FIG. 2 is a front view and a side view showing the mounting fixture for the ventilation fan. Specifically, FIG. 2(A) is a front view showing the mounting fixture for the ventilation fan, and FIG. 2(B) is a side view showing the mounting fixture for the ventilation fan. In FIGS. 1 and 2, the vertically upward direction is defined as the +Z-axis direction, and two axes orthogonal to this Z-axis are defined as the X and Y axes for explanation. The same applies to the following drawings.

[0016] As shown in FIGS. 1 and 2, the mounting fixture 1 for the ventilation fan includes a plate-like body 2 formed in a rectangular shape. This plate-like body 2 has a hole portion 21 formed in a substantially central position in a rectangular shape, and four screw holes 22 formed at each of the four corners, and eight common tightening screw holes 23 formed along the four sides of the hole portion 21. Further, the plate-like body 2 is formed along the periphery of this plate-like body 2, and includes four upright portions 3 that stand up from each side of the plate-like body 2 in the +X-axis direction, and four L-shaped reinforcing metal fittings 4 attached to the connection portions of the respective upright portions 3. Here, each upright portion 3 is formed over the entire circumference of the periphery of the plate-like body 2. In this embodiment, the plate-like body 2 is formed in a rectangular shape, but for example, it may be formed in a circular shape or other shapes.

[0017] FIG. 3 is a cross-sectional view of the main part showing the state where the ventilation fan is attached to the mounting surface via the mounting fixture for the ventilation fan. FIG. 4 is a front view showing the state where the ventilation fan is attached to the mounting surface via the mounting fixture for the ventilation fan. As shown in FIGS. 3 and 4, the ventilation fan 10 has a fan 101, a cylindrical frame 102 that rotatably supports the fan 101, and a flange 103 provided on the frame 102. Further, the ventilation fan 10 includes a cover 104 that covers the fan 101 and a shutter 105 that closes when the fan 101 stops to prevent the intrusion of outside air. This ventilation fan 10 inserts the frame 102 into a ventilation opening H formed in an attachment surface S such as a wall or a ceiling, and is attached to the attachment surface S via the flange 103. Further, the ventilation fan 10 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 tool 1 for the ventilation fan inserts the frame 102 of the ventilation fan 10 into the hole 21 of the plate-like body 2, inserts the frame 102 into the ventilation opening H, and uses a screw SC1 to fasten the flange 103 of the ventilation fan 10 and the plate-like body 2 to the attachment surface S through the co-fastening screw hole 23. Further, by fixing the plate-like body 2 to the attachment surface S with a screw SC2 through the screw hole 22, the ventilation fan 10 can be attached to the attachment surface S. Here, the plate-like body 2 is disposed intervening between the attachment surface S and the flange 103 and projects outward beyond the flange 103. Further, the standing portion 3 is formed at the periphery of the plate-like body 2 and stands toward the opposite side of the attachment surface S. Further, the co-fastening screw hole 23 is formed at a position corresponding to the screw hole formed in the flange 103 for attaching the flange 103 of the ventilation fan 10 to the attachment surface S.

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

[0020] According to this embodiment, the following actions and effects can be achieved. (1) The ventilation fan mounting bracket 1 is positioned between the mounting surface S and the flange portion 103 and includes a plate-like body 2 that protrudes outward from the flange portion 103, thereby improving the airtightness of the gap between the mounting surface S and the flange portion 103. Furthermore, the plate-like body 2 is provided with an upright portion 3 formed on its periphery and rising toward the opposite side of the mounting surface S, so the upright portion 3 can suppress the flow of indoor dust along the mounting surface S along with the indoor air discharged to the outside. Therefore, the ventilation fan mounting bracket 1 can reliably prevent dirt from accumulating around the ventilation fan 10.

[0021] (2) Since the upright portion 3 is formed around the entire periphery of the plate-like body 2, it is possible to suppress indoor dust from flowing along the mounting surface S around the entire periphery of the ventilation fan 10, thereby more reliably preventing dirt from accumulating around the ventilation fan 10. (3) The plate-shaped body 2 is formed in a position corresponding to the screw holes 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 screw holes 23 for fastening the plate-shaped body 2 and the flange portion 103 together, so that the ventilation fan mounting fixture 1 can be easily attached to the mounting surface S using the screws SC1 used in the screw holes formed in the flange portion 103.

[0022] [Second Embodiment] A second embodiment of the present invention will be described below with reference to the drawings. In the following explanation, parts that have already been explained will be denoted by the same reference numeral and their explanation will be omitted.

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

[0024] As shown in Figures 5 and 6, the ventilation fan mounting bracket 1A includes a rectangular plate-shaped body 2A. Furthermore, the plate-like body 2A, like the first embodiment, is equipped with four upright portions 3 and four L-shaped reinforcing brackets 4, as well as protruding portions 5A provided at two locations on each upright portion 3, which extend outward from the upright portion 3.

[0025] Figure 7 is a cross-sectional view of the main part showing the ventilation fan being attached to the mounting surface via a ventilation fan mounting bracket. As shown in Figure 7, the ventilation fan 10 is attached to the mounting surface S, such as a wall, by inserting the frame 102 into the ventilation opening H formed in the mounting surface S and by attaching it to the mounting surface S via the flange portion 103.

[0026] The ventilation fan mounting bracket 1A is installed by inserting the frame 102 of the ventilation fan 10 into the hole 21 of the plate-shaped body 2A, and also inserting the frame 102 into the ventilation opening H, and fastening the flange 103 of the ventilation fan 10 and the plate-shaped body 2A to the mounting surface S with screws SC1 via the screw holes 23. In addition, the plate-shaped body 2 is fixed to the mounting surface S with screws SC2 via the screw holes 22, thereby enabling the ventilation fan 10 to be mounted to the mounting surface S. Here, since the plate-like body 2A has an overhanging portion 5A that extends outward from the upright portion 3, a gap can be formed between the ceiling L, which is a wall surface perpendicular to the mounting surface S, and the upright portion 3 at the overhanging portion 5A.

[0027] In this embodiment as well, the same functions and effects as in the first embodiment can be achieved, and the following functions and effects can also be achieved. (4) Since the plate-shaped body 2A is equipped with an overhanging portion 5A that extends outward from the upright portion 3, a gap can be formed between the ceiling L, which is a wall surface perpendicular to the mounting surface S, and the upright portion 3 at the overhanging portion 5A. Therefore, the upright portion 3 can reliably prevent indoor dust from flowing along the wall surface along with the indoor air discharged to the outside, and reliably prevent soiling around the ventilation fan 10.

[0028] [Modification of the embodiment] It should be noted that the present invention is not limited to the embodiments described above, and any modifications, improvements, etc., that can achieve the objectives of the present invention are included in the present invention. For example, in each of the embodiments described above, each upright portion 3 was formed around the entire circumference of the periphery of the plate-like body 2, 2A, but it does not have to be formed around the entire circumference, and may be formed only on a part of the periphery of the plate-like body 2, 2A.

[0029] Furthermore, in each of the above embodiments, the plate-like bodies 2 and 2A were provided with screw holes 23 for fastening together the plate-like body 2 and the flange portion 103, formed at positions corresponding to the screw holes formed in the flange portion 103 for attaching the flange portion 103 of the ventilation fan 10 to the mounting surface S. In contrast, the plate-like body may be attached in any way as long as it can be interposed between the mounting surface and the flange portion, for example, by using an adhesive or the like to attach it to the mounting surface and the flange portion. [Industrial applicability]

[0030] As described above, the present invention can be widely applied to mounting fixtures for ventilation fans used in the installation of ventilation fans. [Explanation of Symbols]
