PROBLEM TO BE SOLVED: To provide a turbine.SOLUTION: This invention relates to a kind of turbine. The turbine includes a top cover, a bottom cover and blades covered and held between the top cover and the bottom cover. The blades extend up to a central axis and their projections in an axial direction are not overlapped. With this arrangement as above, after the surrounding atmosphere is sucked through the suction ports, the air rapidly flows along the blade and finally discharged out of the discharging ports. As compared with that of a centrifugal fan, the structure of this invention increases an efficiency of suction. As compared with that of a standard turbine, the structure of this invention is more simple, its machining is more easy to perform and so it is possible to reduce its manufacturing cost.SELECTED DRAWING: Figure 1 |
