Lint collection assembly for a dryer appliance

This invention describes a dryer that automatically cleans its lint filter. Instead of a static screen, it uses a roll of filter material that moves across the air vent. A motor winds up the dirty section onto a collection roller and unrolls a fresh section, ensuring the filter is always clean without manual effort.

Why it matters: Since 2019, consumer demand for automated, low-maintenance home appliances has grown significantly. Advances in compact, cost-effective motor and control systems could now make this convenient self-cleaning feature more economically viable for dryer manufacturers.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: ModerateMotor, rollers, custom housing, filter medium.
