摘要： An improved lint handling system for a household laundry dryer is provided. The lint handling system for a laundry dryer has a dryer drum with an exit grill. The lint handling system provides a blower speed increaser to increase airflow in the dryer. The lint handling system also has a lint container and a foreign objects trap connected to the exit grill. Also a lint separator to separate lint from the airflow in the dryer is provided. The lint separator has an input connected to the foreign objects trap and an output connected to the lint container. A laundry dryer having a lint handling system as described is also provided. The lint handling system of the invention also provides a scroll-shaped centrifugal blower housing having a cylindrical base to accept airflow tangentially, a cutoff and a throat region to produce high velocity airflow. The blower housing further has a Helmholtz resonator located in the throat to reduce the acoustic emissions at a blade passage frequency. The lint handling system of the present invention also provides an eyebrow extension of the lint separator to produce a low pressure airflow region.
