With reference to FIG. 1, an exploded view of Taiwan Patent No. 0350530 is disclosed. The wind outlet plate disclosed includes a wind outlet panel A, supports B, a bearing box C and a negative ion generator D.
Four supports B are installed at the back side of the wind outlet panel A. The supports B serve to support the bearing box C of the negative ion generator D on the wind outlet panel A.
It will be appreciated from the prior art that although the primary structure is simple, it is very difficult to detach the structure. Since the structure in the prior art has no filter. Many dusts possibly flow into a room so that the quality of air can not be assured. Moreover, since the prior art has a fixed structure, if a filter is desired to be attached thereon, the wind outlet panel is necessary to be detached. Moreover, since the negative ion generator in the prior art is controlled by a central controlled air conditioner, in order to avoid danger accidents, the air conditioner must be closed for being detached and cleaned.
Although the prior art can provide a preferred air, the maintenance and cleaning works are difficult. For example, closing the central controlled air conditioner will affect the works of other peoples. If the central controlled air conditioner is not closed, it is possible that the electric power may be drained out. Moreover, the effects in dust-proof and germ killing are poor. Therefore, it is apparently that the wind outlet panel is necessary to be improved so that it is more safer and easily detached and has the function of killing germs.
