Abstract: PURPOSE: An oil fire extinguishing method of a fire extinguisher is provided to reduce a cost by extinguishing a fire with water instead of an imported extinguishing agent and to prevent cookers and dishes from being corroded by the extinguishing agent. CONSTITUTION: To extinguish oil fire on a cooker with water, first water is injected through a nozzle from a water tank. The water is injected in a vortex shape by a vortex injecting tip to intercept oxygen. Further, water particles from the vortex injecting tip are mixed with oil particles in similar particle structure by being finely split when hitting on the slant face of an adjusting cap. Due to the split water particles, condensed oil is also split and covered by the water particles. The water particles cool the oil to lower the temperature of the oil under the ignition point of the oil. Thus, finally, oil fire is extinguished.
