A laundry appliance includes a rotating drum for processing laundry. A blower directs process air through an airflow path that includes the rotating drum. A heat exchanger is positioned within the airflow path that dehumidifies the process air. A fixedly-secured lint filter captures lint from the process air at a position upstream of the heat exchanger. A fluid spray system has spray nozzles that deliver fluid to a surface of the fixedly-secured lint filter. Each spray nozzle of the plurality of spray nozzles directs captured lint away from the fixedly-secured lint filter.

A dryer appliance includes a drum defining a chamber for receipt of clothes for drying, an air handler for urging a flow of air through the chamber, and a trap duct in fluid communication with the chamber and comprising a lint filter for filtering lint from the flow of air exiting the chamber. A lint detection assembly includes an emitter for generating light and a receiver for detecting the light that is transmitted through the lint filter, and a controller is configured to determine a lint level based at least in part on the light detected by the receiver, determine that the lint level exceeds a predetermined lint threshold, and implementing a responsive action, such as stopping the cycle, notifying the user, and/or updating an initial cycle time.

A clothes treatment apparatus comprises: a cabinet forming a treatment space for storing clothes; a filter module having a filter portion for filtering out dust from air passing therethrough; an air flow path having a plurality of preset flow paths for directing air to be discharged into the treatment space; a fan for moving the air in the air flow path; at least one valve disposed on the air flow path; a valve actuating module for actuating the valve; and a control part for controlling the valve actuating module so as to select one of the plurality of flow paths. The plurality of flow paths comprise: at least one bypass flow path for directing the air to bypass the filter portion; and at least one filtering flow path for directing the air to pass through the filter portion.

A laundry appliance includes a camera for determining the air flow through an appliance during operation. A controller is operably coupled to the camera. The controller is configured for obtaining one or more images of an air flow indicator positioned in the path of the air flow. An artificial intelligence image recognition process is used to perform image classification and determine whether air flow through the appliance is fully or partially obstructed based on the amount of deflection of the air flow indicator. In the event of an air flow obstruction, operation of the laundry appliance is adjusted.
