Benefits of technology

The present invention provides a ceiling fan that can be assembled in a light steel frame on a ceiling and increase the intensity of ventilation at the same time. The fan has a separation between the top rim of the blade frame and the housing with a gate effect, allowing air to enter from the ventilation holes and then discharge from the exhaust disc. The blade frame design and the flange of the through-hole in the housing intensifies the joining effect between the fan and the wind pipe, increasing structural reliability of the fan.

Problems solved by technology

Apart from the issue of aesthetics, this will more easily result in louder noise.
As a result, it has been long an issue to be solved by industries about how to assemble the ceiling fan in the light steel frame on the ceiling and increase the intensity of ventilation at a same time.

Embodiment Construction

[0018]FIG. 1 shows a structural view of appearance of a ceiling fan of the present invention and FIG. 2 shows an exploded view of the ceiling fan of the present invention. For the ceiling fan of the present invention, an upper side of a housing 20 for accommodating a fan 10 is connected with a wind pipe 30 for feeding in cold or hot air, and a lower side of the housing 20 is formed with a lower frame rim 21 suitably for assembling with a light steel frame. An opening on a bottom surface of the lower frame rim 21 is installed with a chassis 40 having plural ventilation holes 41 and a center of the chassis 40 is formed with a round hole 42 for installing an exhaust disc 50. The fan 10 is installed relatively above the round hole 42.

[0019]Upon implementation, the fan 10 is constituted by a motor 11 and a fan blade 12. The round hole 42 is provided with a set of brackets 43 for installing the fan 10 and the exhaust disc 50 and a top of the housing 20 is provided with a through-hole 22. ...

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.

Description

BACKGROUND OF THE INVENTION[0001]a) Field of the Invention[0002]The present invention relates to a ceiling fan, and more particularly to a ceiling fan which can be assembled in a light steel frame on a ceiling and can increase intensity of ventilation at a same time.[0003]b) Description of the Prior Art[0004]Equidistant grid-shaped frames assembled by light steel are usually provided on a ceiling in a room or a specific area, and interiors of the frames are emplaced with baffles of various materials to achieve soundproofing, fireproofing or aesthetics. Whereas, in addition to providing inside the grid-shaped frames with lighting equipment or inlets and outlets of an air condition system of a building, fan structures will be also installed in the light steel frames for indoor air circulation.[0005]For most of the conventional fan structures, a protruded cover plate will be assembled at a bottom of the fan, forming an abrupt structure on the ceiling, which spoils smoothness and sense ...
