Abstract: 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.

Abstract: A vent system for a dryer, may include an exhaust air conduit configured to provide an airstream to a dryer; a sensor within the conduit and configured to measure the airstream; and a controller configured to receive sensor data from the sensor and determine an airflow. A method for detecting a variation in airflow through a vent of a dryer may include receiving sensor data from at least one sensor in an air conduit of a clothes dryer; determining an estimated airflow based on the sensor data; comparing the estimated airflow to a predetermined expected airflow; and adjusting the estimated airflow in response to the estimated airflow not being within a predefined margin of the predetermined expected airflow.
