The blower guides air from the intake opening 12 to the exhaust opening 13 by rotating the blades via the motor 31 by feeding power. As a result, the ceiling-embedded ventilation fan device 1 sucks in, for example, indoor air from the intake opening 12, and discharges it to the outside through the internal space of the ceiling-embedded ventilation fan main body 11, the exhaust opening 13, the adapter 32, and, for example, a duct. do.

The ceiling-embedded ventilation fan installation frame 2 includes a horizontal flat surface portion 21 and a vertical side surface portion 22.

As shown in FIG. 2, the horizontal flat surface portion 21 is a hollow rectangular frame, and in the arrangement state of the ceiling-embedded ventilation fan device 1, the lower surface of the ceiling-embedded ventilation fan main body 11 is below the horizontal flat surface portion 21. The upper part (flange) of the outer periphery is arranged so as to overlap each other, and the load of the ceiling-embedded ventilation fan main body 11 is received in the vertical direction by being locked by screwing or the like from the lower part to the upper part.

The vertical side surface portion 22 stands up from the outer peripheral side peripheral edge of the horizontal plane portion 21. Here, standing means standing perpendicular to the horizontal plane portion 21. Then, in the state of being arranged on the ceiling, the horizontal plane portion 21 is located vertically above, and the vertical plane portion 22 is erected vertically downward from the horizontal plane portion 21. In the vertical side surface portion 22, the building skeleton 3 is positioned on the outer peripheral surface, in other words, the vertical side surface portion 22 is adjacently arranged on the inner peripheral side of the building skeleton 3, and the vertical side surface portion 22 and the building skeleton 3 are locked. This is a part for fixing the ceiling-embedded ventilation fan main body 11 to the building frame 3. As shown in FIG. 3, the vertical side surface portion 22 includes a plurality of round holes 22a provided in the horizontal direction on the four surfaces. Then, the mounting screw penetrating the round hole 22a is screwed in the horizontal direction with respect to the skeleton 3, that is, from the inner peripheral side to the outer peripheral side in the inner peripheral space in the hollow rectangular shape, so that the vertical side surface portion 22 is attached. The building frame 3 is fixed. At a substantially horizontal position of the round hole 22a through which the mounting screw penetrates, a long hole 22b extending in the vertical direction in the arranged state is provided on at least one of the four surfaces constituting the vertical side surface portion 22. There is.

Further, the ceiling-embedded ventilation fan installation frame 2 can change the area of the opening of the inner peripheral space in the hollow rectangular shape according to the size of the lower surface of the ceiling-embedded ventilation fan main body 11.

Hereinafter, the structure that enables the area of the opening to be changed will be described in detail with reference to FIG.

The ceiling-embedded ventilation fan installation frame 2 is mainly composed of two parts, a U-shaped member 23 having a U-shaped shape when viewed from above when arranged, and an I-shaped member 24 having an I-shaped shape. It is composed of. The ceiling-embedded ventilation fan installation frame 2 is hollow in each horizontal flat surface portion by locking both ends of the I-shaped member 24 to both ends of the U-shaped member 23 so as to coincide with each other. It forms a square shape. The area of the inner peripheral space of the ceiling-embedded ventilation fan installation frame 2 can be changed by the fixed position of the I-shaped member 24 in the concave direction of the U-shaped member 23. The fixed position of the I-shaped member 24 in the hollow square shape can be changed by the slide mechanism.

The slide mechanism includes a groove portion 25 and a protrusion portion 26.

The groove portion 25 is provided as a notch extending in the horizontal direction on two facing sides of the U-shaped member 23, that is, a vertical side surface portion 22 on the opening side (left side in FIG. 2) of each of the facing portion 33 and the facing portion 34. ..

The protrusion 26 protrudes from both ends of the I-shaped member 24 beyond the facing portion 33 and the facing portion 34, and is provided as a protrusion that engages with the groove portion 25 and is slidable in the horizontal direction.

Due to the slidable engagement between the groove 25 and the protrusion 26, the ceiling-embedded ventilation fan installation frame 2 has an I-shaped member 24 indicated by arrows 35 and 36 with respect to the U-shaped member 23. By moving in the horizontal direction, the horizontal width of the hollow shape, in other words, the area of the inner peripheral space can be changed.

The U-shaped member 23 includes four protruding flat surface portions 21a.

The protruding flat surface portion 21a is provided at both ends of the horizontal flat surface portions of the facing portions 33 and the facing portions 34 of the U-shaped member 23 so as to project in the outer peripheral direction of the hollow square shape.

Further, as shown in FIG. 3, the horizontal plane portion 21c of the facing portion 33 and the facing portion 34 of the U-shaped member 23, and the orthogonal portion 37 and the orthogonal portion 38 orthogonal to the facing portion 33 and the facing portion 34. The horizontal plane portion 21d is not located on the same plane. In other words, the horizontal planes of the facing portion 33 and the facing portion 34 are located on the same plane, and the horizontal plane portions of the orthogonal portion 37 and the orthogonal portion 38 are located on the same plane, but the facing portion 33 and the facing portion 34 are located on the same plane. A step 39 is provided between the horizontal flat surface portion and the horizontal flat surface portions of the orthogonal portion 37 and the orthogonal portion 38.

More specifically, in the present embodiment, in the installed state, the step 39 is located so that the horizontal plane portion of the orthogonal portion 37 and the orthogonal portion 38 is located below the horizontal flat surface portion of the facing portion 33 and the facing portion 34. Is provided.

The above is the configuration of the ceiling-embedded ventilation fan 1 and the ceiling-embedded ventilation fan installation frame 2 according to the present embodiment.

Subsequently, the construction procedure of the ceiling-embedded ventilation fan device 1 and the installation frame 2 for the ceiling-embedded ventilation fan will be described.

First, the U-shaped member 23 and the I-shaped member 24 are combined to assemble a hollow rectangular frame. At this time, by using the above-mentioned slide mechanism, the ceiling-embedded ventilation fan main body 11 can be inserted into the frame according to the inner circumference of the flange on the lower surface of the ceiling-embedded ventilation fan main body 11, that is, the size of the intake opening 12. Adjust the central opening to the size that becomes.

Next, the ceiling-embedded ventilation fan installation frame 2 is installed on the building frame 3 assembled in a grid pattern above the top plate 30. At this time, the horizontal plane portion 21 is arranged vertically above, and the vertical side surface portion 22 is arranged below the horizontal plane portion 21. At this time, when the installation frame 2 for the ceiling-embedded ventilation fan is attached by using the protruding flat surface portions 21a provided at both ends of the horizontal flat surface portion 21, it is temporarily placed so as to be hooked on the upper surface of the building frame 3. Is possible. Then, the builder can perform the screwing work between the vertical side surface portion 22 and the building skeleton 3 with both hands free due to the temporary placement.

At the time of screwing work, the builder can insert his head into the inner peripheral space from below the central opening and identify the boundary between the top plate 30 and the building frame 3 through the elongated hole 22b. Therefore, it is possible to prevent the builder from screwing the ceiling-embedded ventilation fan installation frame 2 to the top plate 30 having a strength lower than that of the building frame 3.

Here, if there is an error in the dimensions of the ceiling-embedded ventilation fan installation frame 2 and the building frame 3, the ceiling-embedded ventilation fan installation frame 2 is not reprocessed and deformed by the slide mechanism. Since it can be moved in the horizontal direction, it can absorb dimensional errors, which facilitates installation on the building frame 3.

When the fixing of the ceiling-embedded ventilation fan installation frame 2 to the building frame 3 is completed, only the adapter 32 having a protrusion for connecting to the duct is first fixed to the end of the central opening.

The adapter 32 is fixed to, for example, the I-shaped member 24 or the orthogonal portion 38 facing the I-shaped member 24.

Subsequently, the ceiling-embedded ventilation fan main body 11 is fitted into the central opening with the intake opening 12 facing vertically downward. At the time of fitting, the adapter 32 is provided with a slide groove from the bottom to the top, and the adapter connection surface of the ceiling-embedded ventilation fan body 11 is inserted into the slide groove and lifted upward to form the ceiling-embedded ventilation fan body. 11 and the adapter 32 are in close contact with each other. The builder holds the flange and the horizontal plane 21 in a state where the flange provided on the outer peripheral side of the intake opening 12 of the ceiling-embedded ventilation fan main body 11 is in contact with the back surface (the surface located vertically below) of the horizontal plane portion 21. Screw from below.

The screwing is performed on the horizontal plane 21 of the facing portion 33 and the facing portion 34. Specifically, the flange and the facing portion 33 (or the facing portion 34) are screwed together in a state where the flange and the facing portion 33 (or the facing portion 34) are overlapped in this order from vertically below. As described above, the horizontal plane portion 21c and the horizontal plane portion 21d do not exist on the same plane, that is, the horizontal plane portion 21d constituting the orthogonal portion 38 is below the horizontal plane portion 21d forming the facing portion 33. Therefore, the horizontal plane 21d and the flange are brought into close contact with each other by screwing, and the space between the horizontal plane 21c and the facing portion 33 is crushed and closed. Therefore, it is possible to change the area of the opening of the inner peripheral space with a simple configuration, but it is possible to suppress the air behind the ceiling from being drawn into the room through the space between the horizontal plane 21c and the facing portion 33. ..

That is, the installation frame 2 for the ceiling-embedded ventilation fan and the ceiling-embedded ventilation fan 1 can be easily installed, and even one person can perform the installation work.

After that, a louver is attached below the intake opening 12, but the details of the louver will be described later.

By the way, there are various shapes of the ceiling of the building, in other words, the shape of the building frame 3. Therefore, it is desirable that the ceiling-embedded ventilation fan installation frame 2 can also correspond to various shapes, and this correspondence will be described with reference to FIGS. 4 and 5. FIG. 4 is a diagram showing an example when the ceiling-embedded ventilation fan installation frame is fixed with hanging bolts. Further, FIG. 5 is a diagram showing an installation example of an installation frame for a ceiling-embedded ventilation fan when the exhaust duct of the ceiling-embedded ventilation fan and the suspension bolt interfere with each other.

The vertical side surface portion 22 further includes a hanging bracket connecting portion 27 for locking the hanging bracket A. The hanging metal fitting A is for a ceiling-embedded ventilation fan when the building frame 3 is made of metal such as a lightweight steel frame, or when the strength is low enough to support the load of the ceiling-embedded ventilation fan 1. The installation frame 2 cannot be screwed to the building frame 3. Therefore, the suspension bolt B and the suspension metal fitting A are used to fix the suspension bolt B at a predetermined position. That is, the hanging bolt B is connected to the hanging metal fitting A, and the upper end of the hanging bolt B is fixed to, for example, another building frame.

The hanging metal fitting connecting portion 27 is provided near both ends of the vertical side surface portions 22 in the facing portion 33 and the facing portion 34. Then, as shown in FIG. 4, when the exhaust duct (adapter 32) does not interfere with the hanging bolt B and the hanging metal fitting A, the hanging bolt B and the hanging metal fitting A are placed on the opposite 2 of the ceiling-embedded ventilation fan installation frame 2. Attach two to each side so that they face each other.

On the other hand, when the adapter 32 interferes with the positions of the hanging bolt B and the hanging metal fitting A, it is difficult to change the position of the exhaust duct. If the installation frame for the ceiling-embedded ventilation fan is square, the arrangement of the ceiling-embedded ventilation fan installation frame may be shifted by, for example, 90 degrees, but the ceiling-embedded ventilation fan installation frame 2 has a central opening. Since the area can be changed, it cannot be shifted. Therefore, as shown in FIG. 5, the vertical side surfaces of the facing portion 33 and the facing portion 34 so that the mounting position of the hanging bracket A can be changed so that the positions of the exhaust duct, the hanging bolt B, and the hanging bracket A do not interfere with each other. The metal fitting connection portion 27 is also provided in the portion 22. That is, since the hanging metal fitting connection portion 27 is provided on each side, the position of the hanging metal fitting A can be shifted according to the direction of the exhaust duct, and the position of the hanging metal fitting A can be shifted with respect to the exhaust duct in all directions. The installation frame 2 for a ceiling-embedded ventilation fan can be installed.

Although the preferred embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and all the inventions including the configurations described in the claims are included in the present invention.

The installation frame for a ceiling-embedded ventilation fan and the ceiling-embedded ventilation fan device according to the present invention are useful because they can be easily attached and detached.
