The terms "connected" or "coupled" and the like are not restricted to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "upper", "lower", "left", "right", and the like are used merely to indicate relative positional relationships, and when the absolute position of the object being described is changed, the relative positional relationships may also be changed accordingly.

To maintain the following description of the embodiments of the present invention clear and concise, detailed descriptions of well-known functions and components may be omitted.

The utility model discloses an embodiment discloses a ceiling fan, this ceiling fan is used for installing in the below of the ceiling in the room.

As shown in fig. 1 to 5, the ceiling fan includes a housing 10, a centrifugal fan wheel 20, and a motor 30.

The housing 10 is generally flat rectangular in shape, the top of the housing 10 having mounting structure for mounting to a ceiling, the housing 10 having a generally planar bottom and four sides. A first hollow part 11 which is approximately circular is arranged in the middle of the shell 10; each side of the housing 10 is opened with a second hollowed-out portion 12 having a substantially rectangular shape.

A cover 13 is disposed at the first hollow portion 11, a first grid 111 allowing an air flow to pass through is formed on the cover 13, and a second grid 121 allowing an air flow to pass through is disposed at each second hollow portion 12.

The centrifugal fan wheel 20 is a component of the prior art, which is applied to industrial environment sites, and the centrifugal fan wheel 20 includes a main body 21 and a plurality of spirally bent blades 22 circumferentially arranged on the main body 21 and extending radially, and when the centrifugal fan wheel 20 rotates, the centrifugal fan wheel 20 causes the airflow to enter the fan wheel 20 in the axial direction and flow out from the fan wheel 20 in all radial directions.

The centrifugal impeller 20 is installed in the casing 10, and the axis of the centrifugal impeller 20 is substantially perpendicular to the top of the casing 10, and the impeller 20 is substantially opposite to the first hollow portion 11. A motor 30 is installed at the center of the top of the housing 10, and an output shaft of the motor 30 is connected to the main body portion 21 of the fan wheel 20, so that the motor 30 can drive the fan wheel 20 to rotate.

As can be seen from the above description, the rotation of the fan wheel 20 causes the air flow to enter the housing 10 from the lower portion of the housing 10 through the first hollow portion 11, and the air flow flows out through the second hollow portions 12 on the side portions of the housing 10 under the action of the fan wheel 20.

The utility model provides a ceiling fan's advantage lies in:

1. through setting up centrifugal fan wheel 20 for the region of the below of casing 10 forms the air current and enters into in the casing 10, and makes the air current follow radial all ascending directions outflow, because the air region of the below of casing 10 is very big, therefore, the formation of air current can not be obstructed, therefore, the air-out is effectual, and the noise is low.
