Abstract: A dryer appliance and a method of operating the same to detect blockages are provided. The dryer appliance includes an exhaust conduit that defines a flow restriction and is in fluid communication with a drying chamber. A differential pressure sensor is operably coupled to the exhaust conduit at the flow restriction and a controller is configured for using a measured pressure differential to obtain an air flow rate and determine whether a blockage is present in the exhaust conduit, e.g., by comparing the measured flow rate to a baseline, zero-blockage flow rate.

Abstract: A washing machine appliance includes a wash tub defining a tub inlet, a wash basket rotatably mounted within the wash tub, and a motor including a rotor for rotating the wash basket. The washing machine appliance also includes a fan assembly positioned behind the wash tub and including a plurality of fan blades that are operably coupled to and extend from the rotor. A fan housing is positioned around the plurality of fan blades and defines a fan outlet in fluid communication with the tub inlet of the wash tub such that the fan blades generate a flow of air which is provided into the wash basket when the rotor is rotating.

Abstract: A dryer appliance and method of operation are generally provided. The dryer appliance may include a drying chamber, an air passage in fluid communication with the drying chamber, and a heater in thermal communication with the drying chamber. The method may include motivating an airflow through the drying chamber and the air passage. The method may include measuring a velocity of the airflow through the air passage. Also included may be determining an article load size within the drying chamber based on the measured velocity, and directing a power output at the heater based on the determined article load size.

Abstract: A fan assembly for a dryer appliance is provided. The fan assembly includes an inlet duct that fluidly couples a chamber of the dryer appliance to a fan inlet. The inlet duct includes one or more guide vanes that are configured to direct the air in a manner that improves the pressure rise across the fan, thereby improving appliance performance. For example, the guide vanes may be positioned and oriented to generate a negative pre-swirl of the flow of air, such that the flow of air enters the fan inlet rotating in a direction opposite the direction of rotation of an impeller. Additionally, or alternatively, one or more guide vanes may be positioned and oriented to generate a laminar flow of otherwise turbulent air from the chamber of the dryer appliance.
