Abstract:

A fire extinguishing system for use with gas or electric range stove top to automatically deploy and energize an audible alarm. The system includes a pressurized supply of inert gas within an inflatable bag. A grease fire on the stove top breaks the fusible cord and allows the case to open, releasing the inert gas supply. The inert gas inflates a flame resistant bag to cover the burners of the stove top. The bottom of the flame resistant bag is a specific temperature sensitive material that will decompose on contact with the grease fire. As the bottom decomposes, the flame resistant material surrounds the cooking container containing the grease fire. The grease fire becomes isolated by flame resistant materials and inert gas. The bottom two layers of the bag have an additional layer of non-flammable absorbent fiber between the two layers of the decomposing bottom. The decomposing bottom layer releases the non-flammable absorbent fiber into the cooking container containing the extinguished grease fire to absorb the cooking grease and prevent the cooking grease from re-igniting.
