Abstract

A ceiling fan is disclosed. Above a housing for accommodating the fan is connected with a wind pipe for feeding in cold or hot air and below the housing is a lower frame rim for assembling with light steel. A bottom opening of the lower frame rim is a chassis having ventilation holes and a center of the chassis is a round hole for installing an exhaust disc. The fan is installed relatively above the round hole. A rim of the round hole of the chassis is a blade frame surrounding a fan blade. Separation with a gate effect is formed between a top rim of the blade frame and the housing, so that air enters from the ventilation holes and discharges from the exhaust disc, thereby assembling the entire ceiling fan in a light steel frame on a ceiling and increasing intensity of ventilation at a same time.

Claims

1. A ceiling fan comprising an upper side of a housing for accommodating the fan is connected with a wind pipe for feeding in cold or hot air, a lower side of the housing is formed with a lower frame rim suitably for assembling with light steel, a bottom surface of the lower frame rim is installed with a chassis having plural ventilation holes, a center of the chassis is formed with a round hole for installing an exhaust disc and the fan is installed relatively above the round hole, wherein a rim of the round hole of the chassis is formed with a blade frame surrounding relatively the blade of the fan.

2. The ceiling fan according to claim 1, wherein the top of the housing is provided with a through-hole and a rim of the through-hole is provided with a flange that joins correspondingly with the wind pipe.
