FIRE EXTINGUISHING APPARATUS FOR EASY SUPPRESSING FIRE [0002]

The present invention relates to a fire extinguishing device which is capable of suppressing further fire spread from a fire point of a fire, and which is capable of rapidly suppressing a fire in a block range while suppressing further fire spread.

It is most important to extinguish the fire point quickly by blocking the fire before it spreads. Moreover, if a fire occurs in the apartment, the damage is large, so it is the first priority to suppress the fire.

For this purpose, a sprinkler has been used conventionally. However, if the ignition point is filled with flammable materials such as wood, paper, combustible gas, or oil, the problem is that even if the sprinkler runs at the ignition point, the flame is already spreading to the surrounding area, Frequent. Of course, this spread of fire causes great damage to people and property, so fast and easy fire suppression technology is required.

In order to solve this problem, various fire suppression techniques have been proposed in the past. However, the conventional technology relates to a building material such as a heat insulation material and a building panel most of which is utilized in public housing, and various fire-fighting techniques have been additionally applied to the building material. Of course, such a conventional technology has a limitation in its practical application because it can not but increase the cost of building construction.

In the end, a more realistic and efficient fire fighting technique was required.
