Abstract
The utility model discloses a rotary fan. Blade wheels are driven to rotate by motors. The motors are fixed with an outer cover together. The rotary fan is structurally characterized in that two sets of motors are assembled inside the outer cover by a motor fixing support with a definite distance between axial cords which are horizontally spaced. Wind power which is generated by the blade wheels driven by the motors forms a force moment correspondingly to a support shaft. Thus the outer cover, the motors, and the blade wheels are driven to rotate together. The rotary fan has the advantages of great wind rate, extensive wind power radiation range, and beautiful appearance.
Description
The utility model relates to a kind of spin type fan, belongs to civilian household appliances.
In the prior art, the structure of fan is by the blowing of motor drives single impeller basically, and the angle of this fan rotation is limited, and the scope of wind-force radiation is also limited.In the technological improvement,, solved wind-force radiation scope problem though also there is the motor drives bilobed wheel to occur to the fan of two side-blowings, the influence that factor receptor is long-pending, impeller diameter is restricted, thereby air quantity is little.
The purpose of this utility model is to provide a kind of spin type fan, but the two ends air-out of this fan, and fan can be by clockwise or counterclockwise unidirectional rotation together with outer cover, and air quantity is big.
The purpose of this utility model is achieved in that a kind of spin type fan, comprise motor, impeller, outer cover, back shaft, at the axial opposing end of two motors one impeller is installed respectively, motor, impeller is installed in the outer cover, it is characterized in that said two motors is assemblied in the outer cover by motor fixed rack, motor axis horizontal interval certain distance, the outer cover axis becomes 0 °～45 ° angles with motor axis, and fixedly runing rest and outer cover connect together motor by outer cover, outer cover can be made into straight cylinder type, middle protruding drum type or middle recessed drum type, two ends can be a plane or a cambered surface, and squirrel-cage bar also is installed.When motor is worked, drive two wheel rotation, wind is sucked by outer casing, because the two motors axis is not on same Vertical direction, it has the certain level span each other, so, drive outer cover, motor, impeller thus and rotate around back shaft by clockwise or counter clockwise direction together by relative back shaft the generation one clockwise or anticlockwise moment of wind-force that wheel rotation produces.
Adopted the fan of said structure, not only air quantity is big, and wind-force can comprehensive pair penetrate, and the wind-engaging scope is wide, and is aesthetic in appearance.
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the utility model example structure schematic representation.
In the present embodiment, squirrel-cage shaped outer cover axis and substantially horizontal angle are 60 °, motor 6 relies on motor fixed rack 2 to be assemblied in the outer cover, motor fixed rack 2 is horizontally disposed with, and motor 6 and mouse cage outer cover 4 rely on outer covers fixedly runing rest 7 be connected, an end of motor shaft 5 is equipped with impeller 3, when motor 6 is worked, rotate the relative back shaft 1 of the wind-force that produces by impeller 3 and produce an anticlockwise moment, drive outer cover 4, motor 6, impeller 3 and together press counterclockwise around back shaft 1 rotation.
