Abstract
An improved ceiling fan vane structure minimizes the weight of vanes to reduce to loads and achieve a power saving effect without affecting the structural strength of the vanes. The structural design includes the vanes, each being formed by combining a plurality of laminated plates, in which a middle laminated plate has a hollow slot, and a hollow chamber is created after the vanes are formed. The hollow chamber is maintained hollow or filled with a lightweight material such as glass fiber, cotton, or foam to achieve the effect of reducing the weight of the vanes, so that when a motor of the fan is operated to drive the vanes to rotate and produce air turbulence, the lightweight vanes can reduce the load of the motor to improve its operation efficiency, and achieve the effects of saving power and extending the lifespan of the motor.
Description
- 1. Field of the Invention
- The present invention relates to an improved ceiling fan vane structure, and more particularly to a structure that minimizes the weight of vanes to reduce the load of a motor of a ceiling fan without affecting the structural strength of the vanes, so as to achieve the effects of improving the operation efficiency to save power, and extending the lifespan of the motor of the ceiling fan.
- 2. Description of the Related Art
- In general, windows and doors are available in our living space for facilitating indoor and outdoor airflows, and preventing stale air in the house. However, the effect of facilitating airflows made by the windows and doors is very limited, and in certain situations such as the usage of air-conditioning, a rainy day or a poor outdoor air quality, it is necessary to close the windows and doors. As a result, the ventilation is poor, and the poor ventilation causes a hot and humid indoor environment, and a ceiling fan is generally used for producing air currents and turbulence to lower the indoor temperature and improve the hot and humid environment.
- In general, the ceiling fan hung from the ceiling comprises a hanging frame, a motor case mounted to a lower end of the hanging frame, a transmission motor installed inside the motor case, and a rotor of the motor exposed from a circular through hole that is formed at bottom of the motor case. After the base of the vanes is installed onto a vane frame, the vane frame is fixed onto the rotor of the motor, such that when the motor is operated, the vane frame and its vanes will be rotated together with the rotor of the motor rotor to achieve the effect of producing air turbulence.
- The vanes of such ceiling fan are generally made of wooden plates, but wood is expensive and the manufacturing cost will be increased significantly. Therefore, most of the present existing vanes are made of single-layer or multi-layer composite plates or compressed plates to lower the material cost.
- However, the vanes of this sort made of wooden plates have a relatively heavy weight, causing a relatively large load to the motor of the ceiling fan, and affecting the operation efficiency of the motor. As a result, the ceiling fan consumes more electric power and results in more expenses.
- In view of the drawbacks of the conventional ceiling fan vane structure, the inventor of the present invention based on years of experience in the related industry to conduct extensive researches and experiments, and finally developed an improved ceiling fan vane structure in accordance with the present invention to achieve the effect of minimize the total weight of vanes of the ceiling fan to reduce the load of a motor of the ceiling fan without affecting the structural strength of the vanes, so as to reduce loads, improve the overall operation efficiency, and achieve the power saving effect.
- It is a primary objective of the present invention to overcome the shortcomings of the prior art by providing a structural design that stuffs a lighter material inside the vanes to reduce the weight of the vanes, while maintaining the required structural strength.
- To achieve the foregoing objective, the present invention provides a structural design comprises vanes of a ceiling fan, and each vane is composed of a plurality of laminated plates, of which a middle laminated plate has a hollow slot formed thereon, such that after the vanes are combined and formed, a hollow chamber is formed in the vane, and the hollow chamber can be maintained hollow, or filled with a lightweight material such as glass fiber, cotton, or foam to achieve the effect of reducing the weight of the vanes, so that when a motor of the fan is operated to drive the vanes to rotate and produce air turbulence, the lightweight vanes can reduce the load of the motor to improve its operation efficiency, and achieve the effects of saving power and extending the lifespan of the motor.

- With reference to
FIG. 1 for a schematic view of a structure,FIGS. 2 and 3 for exploded views of a structure, andFIGS. 4 and 5 for schematic views of a structural relation in accordance with the present invention respectively, an improved structure of vanes comprises a plurality ofvanes 10 formed by combining a plurality of laminated plates including an upper laminatedplate 11, a lower laminatedplate 12, and one or more middle laminatedplates 13, and thelaminated plates plates plate 13 includes one or morehollow slots 14 formed at predetermined positions respectively. If there are more than one middle laminatedplate 13, thehollow slots 14 of the middle laminated plates can be installed corresponding to each other or alternatively with one another, such that when the upper and lower laminatedplates plate 13, thehollow slots 14 form hollow chambers inside thevanes 10 respectively, after thevanes 10 are combined and formed, and the hollow chambers are maintained hollow or tilled with alightweight material 20 such as glass fiber, cotton or foam, so as to constitute the improved structure of vanes of a ceiling fan in accordance with the present invention. - From the description above, the design of the
vanes 10 of a ceiling fan in accordance with the present invention adopts a structure made of a multilayer composite material, and forms thehollow slot 14 in the middle laminatedplate 13 to reduce the weight of thevanes 10 without affecting the structural strength of thevanes 10, and the hollow chamber formed by thehollow slots 14 can be filled with alightweight material 20 to concurrently achieve the effect of reducing the weight of thevanes 10 without affecting the structural strength of thevanes 10, so as to achieve the effects of reducing the load of the motor of the fan effectively, and improving the operation efficiency of the motor for driving and rotating thevanes 10 substantially. The invention can reduce power consumption to achieve the power saving effect, and also can extend the lifespan of the motor of the ceiling fan. - In summation of the above description, the present invention improves the structure of the vanes of the ceiling fan to reduce the weight of the vanes without affecting the structural strength, so as to achieve the effects of enhancing the operation efficiency of the motor, saving power, and extending the lifespan of the motor of the ceiling fan. The invention improves the performance over the conventional structure and further complies with the patent application requirements and thus is duly submitted for patent application.
