An appliance (10) for drying and/or washing laundry includes an autonomous fire extinction device (20). The fire extinction device has pipe (26) with an elongate shape and closed at both its longitudinal ends (26x). 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 (12). An extinguishing fluid (29) is inside the space, and is configured to be released by fusion of the pipe wall (26) under the effect of heat produced by a fire or an incipient fire.

Detection of airflow conditions, such as blockage issues, in a dryer laundry appliance is provided. A current or instant calibration is performed utilizing an airflow model to infer, based on current or instant sensor data from sensors of the dryer laundry appliance, an estimated airflow for an exhaust air conduit of the dryer laundry appliance. The estimated airflow is compared to a baseline airflow previously inferred by the airflow model during a baseline calibration using previous sensor data from the sensors of the dryer laundry appliance. An alert is provided responsive to the estimated airflow being below a threshold level relative to the baseline airflow.

A laundry treating apparatus may comprise a cabinet that defines an exterior design; a drum rotatably mounted in the cabinet and configured to accommodate laundry; a drive unit or motor configured to rotate the drum; a hot air supply unit or hot air blower configured to supply high-temperature air to the drum and in communication with the drum; a collection portion or liquid chamber provided to collect water condensed from the drum and in communication with the hot air supply unit; and a drainage pump configured to discharge the water collected in the collection portion outside the cabinet such that the laundry treating apparatus may sense whether the condensate collected in the collection portion is frozen and thaw the frozen condensate. A control method of the laundry treating apparatus may be provided to thaw and operate the laundry treating apparatus.
