[Prior art and its problems]

 As is well known, in kitchen units such as mini kitchens in which a sink and gas appliances are compactly installed, a ventilation fan is installed directly above the gas appliances.

By the way, in this type of kitchen unit, the ceiling plate to which the ventilation fan is attached is formed of calcium silicate plate, which is an incombustible material, and the calcium silicate plate, etc. Since it does not have the strength to hold it with screws, conventionally, as shown in FIGS. 5 and 6, an opening 2 is opened in a ceiling plate 1 formed of a calcium silicate plate or the like, and the ceiling plate 1 is opened from above. At present, the flange portion 5 of the ventilation fan 4 is placed and positioned on the peripheral edge portion 3 of the opening, and then the flange portion 5 is fixedly attached by the screw 6.

However, in the kitchen unit to which the ventilation fan 4 is attached by the conventional method described above, the ventilation fan 4 is installed in the narrow space 8 defined by the ceiling 7 of the kitchen room and the ceiling plate 1 of the kitchen unit. Then, after placing the flange portion 5 of the ventilation fan 4 on the opening peripheral edge portion 3 of the ceiling plate 1 while positioning it, a screw 6 is screwed on the flange portion 5 and tightened to fix the ventilation fan 4 to the kitchen unit. Since it has to be attached to the ceiling board 1, the work of attaching the ventilation fan 4 and the work of connecting the exhaust pipe 9 and the ventilation fan 4 are very complicated, and after the ventilation fan 4 is attached, the ceiling board 1 and the kitchen are installed. Since the veneer 4 is closed to the ceiling 7 of the room, this veneer 10 must be broken when the ventilation fan 4 is maintained, and a new veneer is required. Therefore, there is a problem that maintenance and inspection costs increase.

In order to solve such a problem, a kitchen unit in which a ventilation fan 4 is attached by means shown in FIG. 7 is conventionally known.

In this kitchen unit, a ventilation fan 4 is inserted into the opening 2 from below the ceiling plate 1, and a flange portion 5 of the ventilation fan 4 is pressed against the lower surface of the opening peripheral edge portion 3 of the ceiling plate 1 with a screw 6 It is fixed and held by.

In this case, since the ceiling plate 1 is formed of a calcium silicate plate or the like having low strength, the tip of the screw 6 has a flammable material such as wood disposed on the back side of the ceiling plate 1. The non-combustible material 12 is arranged on the inner peripheral side of the flammable fixing material 11 so as not to burn out. Is made.

However, in the above-mentioned conventional system kitchen in which the ventilation fan 4 is subordinated, the combustible fixing material 11 is arranged in the vicinity of the ventilation fan 4, and the combustible fixing material 11 and the non-combustible fixing material 11 are provided. Since the material 12 is arranged on the back side of the ceiling plate 1, there is a problem that it is difficult to comply with the safety standard stipulated by the Fire Service Act that combustibles must be separated from the ventilation fan 4 by 15 cm or more. Was.

The present invention was devised in view of the current situation, and its purpose is to make it possible to easily install a ventilation fan and to comply with the safety standards stipulated by the Fire Service Act. It seeks to provide a kitchen unit that can be easily adapted.

[0010]

[Means for Solving the Problems]

 In order to achieve the above object, according to the present invention, an opening is formed in a ceiling plate made of calcium silicate plate or the like, and a flange portion of a ventilation fan is screwed and fixed to the peripheral edge of the opening of the ceiling plate. In a kitchen unit configured as described above, a support body having a substantially U-shaped cross section formed of a metal material is fitted to the peripheral edge of the opening of the ceiling plate, and the support body is attached to one side of the support body that abuts on the ceiling back surface side. The ventilation screw is attached to the peripheral edge of the opening of the ceiling plate by screwing the screws.

【Example】

 Hereinafter, the present invention will be described in detail with reference to an embodiment shown in the accompanying drawings.

FIGS. 1 to 3 show a case where the present invention is applied to a mini kitchen K. The mini kitchen K includes a sink 20 and a gas tool 21 connected to the right side of the sink 20. A refrigerator 22 built in below the gas appliance 21, side plates 23 and 24 arranged on the sides of the sink 20 and the gas appliance 21, and fixed to the upper portions of the side plates 23 and 24. The ceiling plate 25 and the back plate 26 are included. In the figure, reference numeral T indicates a shelf, W indicates a faucet, S indicates a ventilation fan switch, and although not shown, a lighting device is arranged on the front side of the ceiling plate 25. .

The ceiling plate 25 is made of a non-combustible material such as calcium silicate plate, and an opening 27 for mounting the ventilation fan 4 is formed at a position right above the gas appliance 21.

A support body 30 made of a metal material such as iron or aluminum and having a substantially U-shaped cross section is fitted to the opening peripheral edge portion 28 of the opening 27.

The support 30 is attached to a lower piece 31 having a narrow width, an upper piece 32 having a wide width, a vertical piece 33 connecting the lower piece 31 and the upper piece 32, and a lower surface of the upper piece 32. The double-sided adhesive body 34 is formed.

The upper piece 32 has a thickness such that a drill tip end portion 29 a of a tex screw 29 screwed to the flange portion 5 of the ventilation fan 4 makes a hole, and a screw portion 29 b of the tex screw 29 is provided in this hole. It is formed to have a width to be screwed.

The support body 30 configured as described above is cut in accordance with the length of one side of the opening peripheral edge portion 28, and is fitted to at least the opposite side portion of the opening peripheral edge portion 28. Of course, when the opening 27 is circular, as shown in FIG. 4, the support 30 may be formed in a shape that fits the arc of the opening peripheral edge portion 28.

Next, when the ventilation fan 4 is attached to the ceiling plate 25 of the kitchen unit K having the above-described configuration, the opening 27 is opened corresponding to the shape of the ventilation fan 4, or the ceiling plate 25 is preliminarily attached to the ceiling plate 25. A similar opening 27 is opened, and the support bodies 30 each having a substantially U-shaped cross section are fitted to opposite sides of the opening peripheral edge portion 28 of the opening 27, respectively, and the double-sided adhesive body 34 prevents misalignment. After that, the housing part of the ventilation fan 4 is inserted from the lower side of the ceiling plate 25 to be connected to the exhaust pipe, and then the above-mentioned text screw 29 is inserted into a screw hole (not shown) formed in the flange portion 5. And tighten.

As a result, the tex screw 29 abuts on the upper piece 32 of the support 30 after the drill tip portion 29a penetrates the ceiling plate 25, and further, by tightening the tex screw 29, After the hole is opened in the upper piece 32, the screw portion 29b of the tex screw 29 is screwed into the peripheral portion of the hole, and the ventilation fan 4 is attached to and held by the ceiling plate 25 as a subscript.

In the mini-kitchen K according to this embodiment, since the ventilation fan 4 is attached as described above, even if the ceiling board 25 formed of a calcium silicate board or the like having a small supporting strength has a supporting strength. Since the ventilation fan 4 can be held through the support plate 30 formed of a large metal plate, and it is not necessary to install the ventilation fan in a narrow space, the ventilation fan 4 can be installed from the lower side of the ceiling plate 25. In addition to greatly improving workability, the ventilation fan 4 can be attached by fitting the support 30 to the opening peripheral edge 28, so when the shape and size of the ventilation fan 4 differ at each installation site. Even so, it is possible to obtain an effect that it is easy to secure the gap between the opening peripheral edge portion 28 and the housing portion of the ventilation fan 4 in conformity with the safety standard defined by the Fire Service Law.

In the above embodiment, the case where the present invention is applied to the mini kitchen K has been described as an example, but the present invention is not limited to this, and the ceiling board having a small supporting strength is used. Of course, it can also be applied to various kitchen units that need to be equipped with a ventilation fan, etc.

[0022]

[Effect of device]

 As described above, in the kitchen unit according to the present invention, even if the ceiling plate is formed of a calcium silicate plate or the like having a low support strength, the ventilation fan is held by the support formed of a metal plate having a high support strength. In addition, the air fan can be attached from the lower side of the ceiling plate, which greatly improves workability, and a support having a substantially U-shaped cross section can be fitted to the peripheral edge of the opening. Since the ventilation fan can be attached by doing so, even if the shape and size of the ventilation fan are different at each installation site, the gap between the peripheral edge of the opening and the housing part of the ventilation fan conforms to the safety standards stipulated by the Fire Service Act. It also has a number of excellent effects such as high security and easy to secure.
