The present document describes a centrifugal ceiling fan. The fan comprises a casing, a motor and a centrifugal propeller. The casing comprises an upper surface comprising an air inlet and a lower surface comprising an air outlet. In an embodiment, the lower surface has a round bowl-like shape including a plurality of openings defining the air outlet. The propeller comprises a shaft and a plurality of blades provided around the shaft. The blades may be curved to push the air in all directions between a first direction substantially perpendicular to the rotation shaft and a second direction substantially parallel to the rotation shaft in order to evenly ventilate the room. The fan may include a heating element for heating the air as it exits from the fan.

Centrifugal ceiling fan

The invention relates to an impeller (1) for a fan, in particular an axial or radial fan having a hub (2) for connecting the impeller (1) to a drive motor and having fan blades (6) which are arranged circumferentially around the hub (2) and having pockets (9) in the hub region, having balance weights (15) which can be fastened therein, aligned in the axial direction. The balance weights (15) are made of U-shaped, bent weight clips made of spring-elastic material, having at least two opposite clip legs extending parallel to each other which are connected to each other via a bend section, and comprise a clamping gap between the clip legs. One of the clip legs extends within the pockets (9) and the other clip leg extends outside of the pockets (9), such that there is a clamping seat on a pocket wall (12) extending in the clamping gap.

The invention relates to a radial fan wheel arrangement consisting of a circular bottom plate (2) and a circular cover plate (3) with a central inflow opening (4), as well as wheel blades (6) running between the bottom plate (2) and the cover plate (3). At least one counterweight (13) is mounted on at least one of the two plates (2, 3) in the plate edge area. Pocket-shaped recesses (9) are configured at least on one side of the plate surface in the space between the wheel blades (6) in the outer edge area of the cover plate (3) and/or the bottom plate (2). At least one counterweight (13) is mounted in the area of at least one of the pocket-shaped recesses (9).

Radial fan wheel arrangement

The present invention relates to a radial fan wheel assembly consisting of a circular bottom plate (2) and a circular cover plate (3) with a central inflow opening (4) and between the bottom plate (2) and the cover disc (3) extending vanes (6 ). On at least one of the two disks (2, 3) in the wafer edge portion is at least one counterweight (13). In the intermediate space between the vanes (6) in the outer edge region of the cover disk (3) and / or the bottom plate (2) are at least on one side in the disc surface pocket-shaped recesses (9). In the region of at least one of the pocket-shaped recesses (9) is at least one counterweight (13).
