Embodiment
A kind of two-way fan and motor thereof hereinafter with reference to description of drawings preferred embodiment according to the present invention.
See also shown in Figure 2ly, it is a two-way single phase fan 2 of the present invention, includes a stator structure 21, a rotor structure 22, a control circuit 23 and an impeller 24.Wherein this stator structure 21, this rotor structure 22 and this control circuit 23 constitute a single-phase motor 3.
This stator structure 21 has one first coil 211 and one second coil 212, and this first coil 211 and this second coil 212 are as magnetic pole of the stator.
This rotor structure 22 has a permanent magnet 221, it is hubbed in the stator structure 21, because the magnetic force change of first coil 211, second coil 212 and 221 generations of permanent magnet makes rotor structure 22 relative stator structures 21 towards first direction 222 or second direction 223 rotations.Because stator structure 21 and the design of rotor structure 22 at present still has the variation of other form, and the magneticaction relation of 221 of first coil 211, second coil 212 and permanent magnets, be not emphasis of the present invention, do not give unnecessary details in this appearance.
This control circuit 23 is located at stator structure 21 places, and control circuit 23 has one first inductive component 231 and one second inductive component 232, in the present embodiment, this first inductive component 231 can be a Hall subassembly with this second inductive component 232, and it is in order to sensing rotor structure 22 position of magnetic poles.When first inductive component 231 starts and second inductive component 232 when closing, rotor structure 22 rotates towards first direction; When second inductive component 232 starts and first inductive component 231 when closing, rotor structure 22 rotates towards second direction.
This impeller 24 links with rotor structure 22, has a plurality of flabellums 241.In the present embodiment, each flabellum 241 shape of impeller 24 are preferably the axially symmetric shape flabellum, and particularly flabellum 241 for example is tabular flabellum, trapezoidal flabellum.When each flabellum 241 is shaped as the axially symmetric shape flabellum, can make air-out of fan forward or reverse air-out all have good air-out efficient.When rotor structure 22 during towards first direction 222 rotation, the air-out direction of impeller 24 is the forward air-out, otherwise when rotor structure 22 during towards second direction 223 rotations, the air-out direction of impeller 24 is reverse air-out.Certainly, according to the difference of the blade structure of impeller design, it is reverse air-out when first direction rotates that fan also can change with rotor structure, and rotor structure is the forward air-out when second direction is rotated.
Fan 2 of the present invention also can be used with a gas net (air filter) (not shown), the gas net can prevent that extraneous dust or impurity from entering fan 2 inside or avoiding user's false touch, and cause the damage of fan 2 structures, and then guarantee that fan 2 is able to good running.
See also Fig. 3, control circuit 23 also comprises a sensing cell 233, a microprocessing unit 234a, a switch element 234b, one drive circuit 30 and a delay cell 234c.
Sensing cell 233 detects the factors such as temperature, humidity or pressure of fan 2 place environment automatically, and produce a feedback signal, and control circuit 23 receives the feedback signal of an external control signal or sensing cell 233 generations, with the magnetic pole of the stator of adjustment stator structure 21, and make rotor structure 22 towards first direction 222 or second direction 223 rotations.
This microprocessing unit 234a receives external control signal or feedback signal, produces one first signal then.And acceptance is from a secondary signal of first inductive component 231 or second inductive component 232, export one the 3rd signal to drive circuit 30, changing the induced magnetism of first coil 211 and second coil 212, and the direction of rotation and the rotary speed of control rotor structure 22.
This switch element 234b receives first signal and selects to start this first inductive component 231 or this second inductive component 232, first inductive component 231 or second inductive component 232 produce the result of sensing rotor structure 22 rotations one secondary signal and export microprocessing unit 234a to.
This first inductive component 231 and this second inductive component 232 lay respectively at that fan 2 is just changeing and the best sensed position when reversing.This first inductive component 231 can be a Hall subassembly with this second inductive component 232.In the present embodiment, this first inductive component 231 and this second inductive component 232 only have an inductive component to be activated when forward or reverse.The startup of inductive component and the mode of closing can also can manually be controlled by control circuit or microprocessing unit control.
This delay cell 234c is between microprocessing unit 234a and drive circuit 30, can keep in the electric current of delay, be burnt because of the overcurrent that fan 2 conversion direction of rotation are produced to avoid microprocessing unit 234a or drive circuit 30 from microprocessing unit 234a or drive circuit 30.
Via said structure, two-way fan 2 of the present invention can be according to actual needs, by the direction of rotation that changes rotor structure 22, air-out direction with conversion fan 2, compare existing structure, fan 2 all has the inductive component that is positioned at best sensed position because of rotating and reverse, and therefore can not change and reduction fan 2 usefulness because of the direction of rotation of rotor structure 22.In addition, after using after a while, impeller 24 or gas net can be accumulated dust unavoidably, and at this moment, two-way fan 2 of the present invention can be removed impeller 24 or the online dust of gas by changing the mode of wind direction.
As mentioned above, according to a kind of bidirectional fan of the present invention and motor thereof can be according to actual needs with Forward or reverse air-out, and first inductive component can be respectively according to different rotations from second inductive component Direction and started or close with the magnetic pole of sensing rotor structure correctly, is compared existing structure, No matter rotor structure is with first direction or second direction rotation, and the fan Bidirectional outlet air all has good Air-out efficient; In addition, because the design of delay cell can cushion fan weak point when changing direction of rotation The generation of road electric current, and then guarantee that the use state of fan is safer, in addition, the user is also Can utilize the change of fan air-out direction, remove flabellum or the online dust of gas, really have good The product practicality.
The above only is illustrative, but not is restricted person. Any do not break away from spirit of the present invention with Category, and to its equivalent modifications of carrying out or change, all should be included in the claim of the present invention.
