Description

Automatic fire extinguisher for kitchen

The present invention relates to a kitchen automatic fire extinguisher installed on a wall between a gas stove in a kitchen and a stove hood so as to rapidly suppress a fire in a gas stove or the like, The present invention relates to a kitchen automatic fire extinguisher capable of quickly suppressing a kitchen fire by injecting a fire extinguishing liquid for fire extinguishment inside a fire extinguisher main body by an operation in which a nozzle rotates by a spring without an operating means.

In general, when a fire occurs, fire extinguishers are used to quickly extinguish the fire promptly. In the case that the scale of the fire is large and the fire extinguisher is difficult to suppress, the fire department uses water or chemicals to suppress the fire.

These fire extinguishers are divided into fire extinguishers in which gas is injected, fire extinguishers in which liquid is injected, and fire extinguishers in which powder is injected, depending on the type of extinguishing agent, and are classified into an accumulative fire extinguisher and a pressurized fire extinguisher according to the injection principle. A fire extinguisher that is mainly used in homes and offices is a powder fire extinguisher that is sprayed with a light pink powder and is an accumulator fire extinguisher.

Fire extinguishers can also be classified according to their use. They are fire extinguishers such as wood grade A class fire extinguishers, B class fire extinguishers for oil fires, C class fire extinguishers for electric fires, D class fire extinguishers suitable for fire by metal or metal powders , And K class fire extinguisher for kitchen fire.

It is not easy to suppress the fire due to the nature of cooking oil in which the temperature difference between the ignition point and the flash point is small and the boiling point is higher than the ignition point. That is, in the case of edible oil, even if the flame is removed by suffocating the surface of the fire by using fire extinguishing liquid or fire extinguishing powder, it is often recalled immediately, so it is difficult to suppress the fire by a general fire extinguisher. Furthermore, fire extinguishing devices such as sprinklers installed on the ceilings of homes and restaurants can not directly spray water on the gas stove due to the cooking hood located on the upper side of the gas stove, so that it is hardly effective in suppressing the kitchen fire.

Accordingly, in the case of kitchen fire caused by cooking oil, a fire extinguishing agent capable of choking the surface to remove the flame and rapidly cooling the combustion source is required, and gas fire extinguishing agents and fire extinguishing agents are used as fire extinguishing agents. Therefore, K-class fire extinguishers for the suppression of kitchen fires are filled with reinforcement liquid and usually consist of spray type.

However, when a fire occurs, people are often embarrassed, so it is not easy to find a fire extinguisher provided in the kitchen. As a result, it is difficult to promptly suppress the fire in the kitchen, and it is also difficult to suppress the fire by directly operating the fire extinguisher.
