Abstract: A dryer appliance, as provided herein, may include a cabinet, a drum, a motor, an impeller, and a housing. The motor may be mounted within the cabinet. The impeller may be in mechanical communication with the motor to motivate rotation of the impeller about an axial direction. The impeller may be rotatable about the axial direction to urge a flow of air from the chamber of the drum to a vent of the cabinet. The housing may include a front panel and a rear panel. The front panel and the rear panel may be spaced apart along the axial direction by a housing cavity within which the impeller is positioned. The front panel may define an entrance upstream of the impeller. The rear plate may define a circular groove may extend rearward from the housing cavity and be concentrically aligned with a circumferential perimeter of the impeller.
