BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention pertains generally to a cross-flow fan, and more particularly to a combined structure of cross-flow fan which is easily manufactured and assembled.
2. Description of the Background Art
A conventional cross-flow fan mainly comprises a stator mounting, a rotor mounting, a fan and a housing. The conventional rotor mounting comprises a magnet ring, wherein the magnet ring cannot be manufactured together with the fan, which is typically made of plastic, because of the differences in materials. Alternatively, after the fan is manufactured, the magnet ring is installed in the fan for engagment with the fan. The conventional way to combine them is to adhere the magnet ring and fan together. However, such an installation process easily results in the ruin of fan blades so that it is difficult to manufacture the fan, and the quality is difficult to control. Additionally, the conventional housing of the cross-flow fan comprises an upper housing and a lower housing which are difficult to be combined.
Accordingly, there exists a need for a cross-flow fan having components that are easily and readily assembled together, thereby maximizing the quality of the fan. The present invention satisfies these needs, as well as others, and generally overcomes the deficiencies found in the background art.
BRIEF SUMMARY OF THE INVENTION
The present invention is a combined structure for a cross-flow fan which generally comprises a rotor mounting having a magnet ring and a coil enclosed therein, a fan mounted beneath the rotor mounting, means for attaching the fan to the rotor mounting that provides for easy assembly of the rotor mounting and the fan together, a stator mounting mounted above the rotor mounting, a housing, and a means for attaching the stator mounting to the housing. The housing includes an entry and an exit and contains the rotor mounting, the fan and the stator mounting.
An object of the invention is to provide a combined structure of a cross-flow fan such that the rotor mounting is easily engaged with the fan, and the outer housing is easily assembled together.
Another object of the invention is to provide a combined structure of a cross-flow fan wherein the elements can be respectively manufactured and assembled such that the cross-flow fan can be easily assembled and the quality of the cross-flow fan can be controlled.
Another object of the invention is to provide a means for easily attaching the fan to the rotor mounting such that rotation of the rotor mounting causes a corresponding rotation of the fan.
Still another object of the invention is to provide a means for easily attaching the stator mounting onto the housing so that the stator mounting and the housing can be easily assembled together.
Further objects and advantages of the invention will be brought out in the following portions of the specification, wherein the detailed description is for the purpose of fully disclosing preferred embodiments of the invention without placing limitations thereon.
