Automated kitchen hood fire trap

A method for suppressing fires on a cooking range comprising:

• detecting conditions indicative of a fire on a range top;
• deploying a fireproof textile shroud from a vent hood positioned above said range top surface surface via gravity-assisted release mechanism;
• creating a sealed fire suppression area by securely coupling a ferromagnetic weighted perimeter of said shroud to said range top surface through magnetic attraction;
• depriving a fire of oxygen within said fire suppression area by complete enclosure of the cooking surface;
• and
• dispensing a fire suppressing liquid through at least one nozzle into said fire suppression area after a predetermined time delay following deployment of said shroud to ensure shroud sealing is complete before liquid application.

A kit for retrofitting an existing kitchen vent hood with an automated fire suppression system comprising:

• a fireproof textile shroud configured to be installed within said vent hood having a weighted perimeter with embedded ferromagnetic properties;
• at least one release mechanism configured to retain said shroud in a non-deployed state and release said shroud upon activation via gravity deployment;
• at least one sensor configured to detect conditions indicative of a fire;
• a manual activation switch;
• a control circuit configured to trigger said release mechanism upon receiving signals from said at least one sensor or said manual activation switch;
• a reservoir configured to hold a fire suppression liquid;
• at least one nozzle configured to dispense said liquid toward a range top surface;
• and
• installation hardware for mounting said components within said existing vent hood including magnetic coupling elements for secure shroud attachment.
