Abstract
A laundry appliance uses a determination of volumetric airflow rate after a steady state condition is reached to determine the accumulation of lint in filter. Based on the determination, various actions can be taken including notifying the user, shutting off the appliance, initiating an automatic cleaning sequence for one or more lint filters, and combinations thereof. One or more temperature sensors, relative humidity sensors, and weight sensors are used to provide measurements for determining the volumetric airflow rate.
