Abstract
An appliance () for drying and/or washing laundry includes an autonomous fire extinction device (). The fire extinction device has pipe () with an elongate shape and closed at both its longitudinal ends (). The pipe includes a fusible thermoplastic wall defining an internal space. The pipe is thermoformed to give it a particular shape in the unconstrained free state corresponding to its mounted position inside the enclosure (). An extinguishing fluid () is inside the space, and is configured to be released by fusion of the pipe wall () under the effect of heat produced by a fire or an incipient fire.
