摘要： A housing for receiving an impeller is provided. The housing includes a transition duct that extends between a volute of the housing and an exhaust exit of the housing. The transition duct defines a bend between the volute of the housing and the exhaust exit of the housing. Cross-sections of the transition duct upstream and downstream of the transition duct define a substantially rectilinear shape. A related dryer appliance is also provided.

摘要： A housing for receiving an impeller is provided. The housing includes a transition duct that extends between a volute of the housing and an exhaust exit of the housing. Cross-sections of the transition duct continuously vary from an inlet cross-section of the transition duct to an outlet cross-section of the transition duct along a length of the transition duct. A related dryer appliance is also provided.

摘要： An impeller assembly including a housing and an impeller is provided. The impeller is positioned within a volute of the housing and includes a hub and a plurality of blades. The plurality of blades are spaced about the hub along a circumferential direction of the impeller. The plurality of blades include a first pair of blades and a second pair blades. The first pair blades defines a first gap along the circumferential direction at a radially outer portion, and the second pair blades defines a second gap along the circumferential direction at a radially outer portion. The first gap is unequal to the second gap in order to reduce an amount of noise generated by the impeller assembly.
