1. An appliance for drying and/or washing laundry, comprising:
an external enclosure of generally parallelepipedic shape and comprising at least one first removable face panel,
a drum located in said enclosure and rotatable about an axis,
the drum comprising an internal cavity configured to receive laundry,
a motor for driving in rotation the drum about the axis, the motor being located in the enclosure under the drum, and
a system for heating and generating a flow of hot air through said cavity, the system being located in said enclosure,
an autonomous fire extinguishing device comprising:
at least one pipe with an elongate shape and closed at both longitudinal ends, the pipe comprising a fusible thermoplastic wall delimiting an internal space, the pipe being thermoformed in order to impose on the pipe a particular shape in an unstressed free state corresponding to a mounting position inside the enclosure, and
a fire-extinguishing fluid within said space, the fire-extinguishing fluid being configured to be released by fusion of the wall of the pipe under an effect of heat provided by a fire or a fire departure,
wherein the device is configured to be mounted in said enclosure by dismounting and removing said first face panel, the device comprising two portions, comprising a first portion in the shape of a cradle which extends between the drum and the motor, from said first face panel to a face panel of the enclosure opposite said first face panel, and a second portion which extends on a side of said first face panel, said first portion being formed by a first segment of the pipe which forms a loop delimiting a periphery of said first portion, and said second portion being formed by a second segment of the pipe.
