Method and apparatus for automatic extinguishment of fires in deep fryers

摘要

A deep fryer with an automatic fire extinguishing system. The oil storage tank is attached to the oil reservoir of the deep fat fryer. A drain valve controls drainage of oil in the deep fryer oil reservoir to the oil storage tank. A fire sensing device is attached to, and controls, the drain valve and opens the drain valve when a fire is detected. The oil storage tank smothers any fire from oil inside it by preventing sufficient air flow to keep the fire burning. Any remaining oil which has not drained the into the oil storage tank quickly burns out and the fire is extinguished. A drain valve in the oil storage tank allows the oil to be recovered and placed back into the oil reservoir of the deep fat fryer for reuse. An air valve in the oil storage tank allows air to evacuate the tank as it is being filled with oil.
