Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a ventilation fan mounting structure for a kitchen stand such as a kitchen unit installed in a small apartment house or a one-room apartment.
[0002]
[Prior art]
Conventionally, small-scale apartments and studio apartments usually use a small-sized kitchen unit called a mini-kitchen, which is installed in a small space. Therefore, the frontage dimensions are usually 900 mm and 1200 mm, the depth dimension is generally 500 mm, and the height dimension is optimally 1900 mm as the dimension that fits under the interior beam of the apartment house. Have been.
The kitchen unit has a box shape as shown in FIG. 3 (a), and its structure is divided into a lower unit 20 and an upper unit 10, and the two units are assembled at the installation site to be self-standing. I have. The lower unit 20 includes a sink 22 made of stainless steel or the like, a heating device 23 such as a one-port electric stove or a one-port gas stove, a countertop 21 made of a metal plate made of stainless steel or the like in which a faucet 24 and the like are mounted and incorporated. At the lower part, a cabinet 25 with a door capable of storing a small refrigerator 26 and the like is provided.
On the other hand, the upper unit 10 is provided with a storage box 14 and a light 15 between the side panels 11, 11, the back panel 12, and the ceiling panel 13 on both sides that use incombustible materials due to regulations of the Fire Service Law. Has a structure in which a ventilation fan 16 is attached, and a piping duct is connected to the ventilation fan 16 to exhaust air to the outside.
[0003]
Conventionally, the installation work of the ventilation fan 16 in the above-described upper unit requires installation on site because the installation position of the ventilation fan and the type of the ventilation fan differ depending on the building and the room, so that the ventilation fan can be installed in the factory in advance. And local construction is normal.
As shown in FIG. 3B, a conventional method of mounting a ventilation fan at an installation site is as follows. First, a ventilation fan mounting opening 13a having a predetermined size corresponding to the external dimensions of the ventilation fan main body is provided at a predetermined position on a ceiling plate 13. The ventilation fan main body 16a is inserted from below into the ventilation fan mounting opening 13a, and the flange portion 16b of the ventilation fan main body 16a is fixed to the ceiling plate 13 with the mounting screw 17. In consideration of the holding force and strength of the mounting screw 17, a decorative noncombustible plate having a thickness of about 15 mm is usually used.
[0004]
[Problems to be solved by the invention]
By the way, in recent years, the cost of this type of kitchen unit has been reduced and the cost reduction measures as a kitchen maker have become an important issue. This allows cost reduction.
As a measure to improve the workability at this installation site, it is conceivable that the thickness of the ceiling plate itself can be reduced so that the cutter knife can perform cutting for drilling the ventilation fan mounting opening 13a. When the plate thickness is reduced, a problem arises in that the holding force of the mounting screw for mounting the ventilation fan body is reduced.
[0005]
SUMMARY OF THE INVENTION It is an object of the present invention to provide a mounting structure for a ventilation fan that can reduce the thickness of a ceiling panel by a fixing method that does not use mounting screws.
[0006]
[Means for Solving the Problems]
The present inventors have conducted various studies on a mounting structure for solving the above-described problem, and as a result, came to the conclusion that the mounting structure can be solved by using a mounting tool having a relatively simple shape.
[0007]
The ventilation fan mounting structure according to the present invention includes a ventilation fan main body having a substantially rectangular ventilating fan mounting opening formed in a ceiling plate of a kitchen unit or the like, and a flange portion at a periphery of the opening facing downward. A mounting structure of a ventilation fan that is inserted and mounted from below so that the flange portion is located on the lower surface side of the periphery of the ventilation fan mounting opening of the ceiling plate, and is provided on a periphery of the ventilation fan mounting opening of the ceiling plate. A fitting portion having a substantially U-shaped cross section to be inserted and fitted, and a hanging piece having a tip of a lower piece bent downward at the fitting portion, and a lower surface side of the lower piece, A notch for allowing a part of the hanging piece to be able to bend horizontally in a state where the flange portion is overlapped is provided with a fitting provided at a bent portion of the lower piece and the hanging piece, and The fitting part is for mounting the ventilation fan on the ceiling plate The fitting is inserted and fitted to the peripheral edge of the mouth, the fitting is locked to the ceiling plate in advance, and the ventilation fan main body is inserted into the ventilation fan mounting opening of the ceiling plate, and the flange portion of the ventilation fan main body is positioned below the fitting in the fitting. After overlapping on the lower surface side of the piece, the hanging piece of the part where the notch portion of the mounting tool is provided is bent so that the bent portion of the hanging piece is positioned on the lower surface side of the flange portion of the ventilation fan main body. The ventilation fan is mounted so that the flange portion of the ventilation fan main body is supported by the bent portion of the hanging piece of the mounting tool.
[0008]
BEST MODE FOR CARRYING OUT THE INVENTION
In the present invention, the thickness of the decorative non-combustible plate as the ceiling plate is set to about 6 mm so that the mounting screw is not used and the drilling and cutting process can be performed using a cutter knife.
On the other hand, the fitting is formed by bending a steel plate or the like having a thickness of about 1 mm, and the fitting portion having a substantially U-shaped cross section in the fitting has a ceiling plate having the above-mentioned thickness. A bent portion formed by bending a hanging piece in a fixture for supporting the flange portion of the ventilation fan main body is formed so as to be able to be inserted and fitted without a gap to the flange portion of the ventilation fan main body. It is preferable that the lower surface side be sufficiently hooked, and pliers (pliers) or the like are used for bending the hanging piece.
It is preferable that the fittings are inserted one by one (four in total) into substantially the center of each side of the substantially rectangular ventilation fan mounting opening.
[0009]
