Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a flameproof device for kitchens to prevent fires caused by flames in the home, especially in the kitchen.

<Prior art> Generally, the exhaust means for heating equipment in the kitchen is
For example, as in Japanese Patent Laid-Open No. 61-58608, various studies have been made regarding the exhaust structure inside the main body of the cooking appliance. However, if these cooking appliances are hung or wall-mounted and a heating device such as a gas stove is installed below, or if these cooking appliances are not installed and there is a storage shelf, etc. above the gas stove. At present, little consideration has been given to flame-retardant devices in case the tempura oil accidentally catches fire when cooking tempura on a gas stove.

<Problems to be solved by the invention> In view of the above-mentioned circumstances, the present invention is designed to solve the problem in cases where a storage shelf or the like is installed above a heating device such as a gas stove, and if tempura oil burns and flames rise. Another object of the present invention is to provide a flameproofing device for kitchen, which minimizes the height of the flame.

<Means for solving the problem> The present invention is a kitchen unit in which a cooking/heating device using fuel such as gas or electricity and a ventilation hood are placed opposite to each other on the ceiling side.
A noncombustible partition plate made of a punched plate, a lath plate, a wire mesh, etc., which has a large number of openings with diagonal or vertical flanges around the periphery, is arranged with hanging fittings.

In this case, the partition plate is a partition plate whose total opening area is at least larger than the opening area of the ventilation system,
Further, the hanging fitting may have a sliding shaft structure that moves up and down, or the hanging fitting may have a structure consisting of a fixed support leg and a movable hook made of a shape memory alloy.

<Function> Due to the above structure, if the tempura oil catches fire and a flame rises, the flame will come into contact with the partition plate laid horizontally at a predetermined position (height), and the partition plate will A type of air supply baffle plate was used, and the flame rose slightly above the punched holes and mesh.
Suppresses the force of the flames and prevents the fire from spreading to storage shelves, etc. Of course, the location of this partition plate can be changed depending on the stove used.

<Example> Hereinafter, the present invention will be described in detail based on the drawings of the example.

The drawings show an embodiment in which the cooking and heating equipment is in the form of a gas stove, and 1 is a kitchen unit in which a gas stove 7 and a ventilation hood 3 are placed opposite each other on the ceiling side, as shown in FIG. This is a rectangular non-combustible partition plate made of a punching board with a large number of holes 4 installed at a predetermined upper position, and the partition plate 1 has a storage shelf 3a protruding from the front side arranged on the ceiling side. It is attached to fixed hanging fittings 2 hanging from the four corners of a ventilation hood 3, and these hanging fittings 2 and a partition plate 1 with holes 4 form a flameproofing device 5. In this case, the partition plate 1 itself may have a structure in which a diagonal or vertical flange portion 12 is formed around the periphery and the central portion is raised.

To explain this effect now, first, place the cooking pot 6 on the gas stove 7 directly below the partition plate 1, and boil it to a predetermined temperature.

Here, for example, if the cooking pot 6 ignites tempura oil (not shown) when frying tempura in a tempura pot or leaves the site, and this flame a rises, the gas stove stand 7 and the storage shelf 3a Since the partition plate 1 is installed in advance at a predetermined intermediate position, the flame a reaches the partition plate 1, the air supply to the flame a decreases, and some flame a escapes from the punch hole 4. It will be about. That is, the height of the flame a is suppressed by the partition plate 1, and the flame a does not reach the storage shelf 3a side. However, since the opening area of the partition plate 1 is larger than the opening area of a ventilation fan or the like (not shown), when the partition plate 1 acts as a flameproof device, the ventilation efficiency does not deteriorate.

In this case, FIGS. 4A and 4B and 5A and 5B show other embodiments in which the hanging fittings of the partition plate are movable. That is, in FIG. 4A, hanging fittings 2 arranged on all sides are attached to a vertical slide shaft 9 equipped with a shape memory alloy spring 8 that shrinks when heated, and a vertical slide shaft 9 is attached to the lower end of the slide shaft 9. The installed partition plate 1 is in a raised position as the spring 8 contracts and the slide shaft 9 is lifted up in a normal state (alloy cooling state) when the flame a does not rise. Here, the flame a rises more than necessary and the spring 8
When the spring 8 is heated, the spring 8 contracts due to the action of shape memory, and in conjunction with this, the slide shaft 9 lowers to push down the integrated partition plate 1 to a predetermined position. Therefore, similarly to the above, the rising flame a is suppressed to a constant height by this partition plate 1 (see FIG. 4B).

In FIGS. 5A and 5B, the partition plate 1 is supported by a claw portion 10a of a hook 10 whose upper end, to which a heat-shrinkable spring 8' is attached at the lower end, is pivoted to the machine frame. However, a cable 11 such as a chain having a length that stops at a predetermined position is arranged at the corner of the partition plate 1. 8" is a balance spring. In this case,
Since the flame a rises more than necessary and causes the spring 8' to contract due to its shape memory and rotates the hook 10, the partition plate 1, which is locked in stages to the claw portion 10a of the hook 10, comes off and falls. , the partition plate 1
is stopped at a predetermined height position by the support rope 11, and the rise of the flame a is suppressed.

Further, FIGS. 6 and 7 show other embodiments of the partition plate. The partition plate 1 in this case has an oblique or vertical flange 12 bent around its periphery (oblique in the illustration), and punch holes 4 are also punched in the flange 12.

If such a partition plate 1 is used, since the airflow has the flange portion 12 around it, the airflow will be concentrated inside, and the flame a will not creep out to the outer periphery of the partition plate 1. Of course, the height of the flame a itself can be suppressed by the partition plate 1.

<Effects of the invention> As mentioned above, the flame retardant device for kitchen according to the present invention has the following effects:
By installing a partition plate with a large number of openings (punch holes, mesh, etc.) with hanging metal fittings at a predetermined height of the cooking/heating equipment, oil can catch fire during tempura cooking, etc. Even if flames start up, the flames hardly come out above the partition plate, thus preventing the fire from spreading to storage shelves, etc. on the ceiling side, and alleviating fear caused by the force of the flames rising.
As a result, rapid fire extinguishing operations can be carried out. In addition, the present invention has a very simple structure, so it has practical effects such as good appearance and low cost.
