  • Patent number: 6648077
    Abstract: A fire extinguishing system is adapted particularly for incorporation with a clothes dryer in a home laundry area, for extinguishing any fire occurring from ignition of lint or other combustible material. The system may also be installed with other large, heat producing appliances (kitchen stove, etc.) for extinguishing any fire resulting therefrom. The system includes one or more conventional, heat activated fire extinguisher spray heads connected to the main water line of the structure. Each extinguisher head is secured in a fitting including an automatically actuated water shutoff valve, which closes after the fire has been extinguished to reduce water damage to the surrounding area. The system also includes an automatic disconnect or shutoff for at least the electrical circuit associated with the appliance which causes activation of the extinguisher head, and may further include an automatically actuated local (household) and/or distant (fire department) alarm.
