Abstract:
1. An appliance fire extinguisher comprising: a container containing a pressurized fire retardant; a delivery tube connected to the container and in fluid communication with the pressurized fire retardant; a fusible tip disposed at a distal end of the delivery tube that seals the delivery tube, wherein the distal end is disposable within the appliance and wherein the fusible tip is adapted to release the fire retardant from the container into the appliance upon melting of the fusible tip when the fusible tip is exposed to a temperature that exceeds its melting temperature; and a pressure-actuated switch connected to the container and in fluid communication with the pressurized fire retardant, wherein the pressure-actuated switch is connectable to a power supply circuit of the appliance for shutting off power to the appliance when a pressure in the container drops below a predetermined value as a result of the fire retardant being released from the container.
