    摘要: A blower assembly for an appliance defines a radial direction, a circumferential direction, and an axial direction. The blower assembly includes a motor, a housing, and an impeller. The housing has a front wall and a rear wall defining a volute with the impeller positioned therein. The impeller is mechanically coupled to the motor for rotating to direct a primary airflow into a primary airflow inlet of the housing and throughout the appliance. Further, the impeller includes a hub wall and a shroud wall. The should wall is spaced apart from the front wall of the housing along the axial direction to define a gap through which a secondary airflow can pass. An inner edge of the shroud wall has a shroud feature that causes the secondary airflow to align with the primary airflow entering the primary airflow inlet so as to minimize turbulence.

    摘要: A fan and a cleaning device are provided. The fan has a housing assembly, a fan cover, a wind wheel, and a first diffuser. The fan cover is mounted on the housing assembly and fits with the housing assembly to form an accommodating cavity. The wind wheel is provided in the accommodating cavity and fits with a side wall of the accommodating cavity to form an air inlet channel. The first diffuser is provided in the accommodating cavity, and has first fan blades and a mounting hub. The mounting hub, the first fan blades and the side wall of the accommodating cavity together provide a first diffusion channel. The air inlet channel is in communication with the first diffusion channel in series.

    摘要: A ceiling fan mounting assembly that includes a ceiling fan box that is positioned at least partially through an opening in a ceiling. The ceiling fan box includes a riser portion that is positioned within the ceiling in use and includes a channel with a partially enclosed perimeter. The ceiling fan mounting assembly also includes a mounting bracket that has a base portion with an opening and a mounting finger that extends away from the base portion. The mounting bracket can connect to the ceiling fan box where the opening extends at least partially around the outer perimeter of the riser portion. The mounting finger is received within the channel and can translate within the channel as the mounting bracket moves relative to the ceiling fan box.
