Description
Technical field：
The invention belongs to household electrical appliance technical field, is related to a kind of electric fan for automatically adjusting wind-force and inverting wind direction.
Background technology：
When blower fan, one very big worry is had, in many scenes, the space residing for us only allows to place a typhoon
Fan, although fan has the function of yaw now, when wanting reverse position to want blower fan, it is necessary to manually adjust, it is special
It is not in the case where special case is very compact, can seems pretty troublesome, although some existing fans can rotate wind directions with 360 degree,
But when just for needing a reverse wind direction, 360 degree of wind direction, just seem and waste very much, as being placed in fan
Bedroom, between desk and bed, when end of handling official business wants to lie on a bed rest, to go to rotate a leeward manually
Fan, air outlet direction is rotated back on bed, so, just seem trouble.
The content of the invention：
In view of the above-mentioned deficiencies in the prior art, it is an object of the present invention to provide a kind of electricity for automatically adjusting wind-force and inverting wind direction
Fan.Method of the present invention by connecting the single-chip microcomputer of a controllable motor reversal to the motor of electric fan, changes motor
Steering so that change the wind direction changeabout wind direction of fan, then by going to change blade structure so that the wind-force of air-supply and side
To being further changed；Simultaneously by control system adjust automatically wind-force size, reach human body preference temperature.
To achieve these goals, present invention employs following technical scheme：One kind can automatically adjust wind-force and reversion wind
To electric fan, including flabellum, micromachine, motor, support frame for fan and control system；Described motor is arranged on wind
Fan on support frame, motor rotary shaft end is provided with circular ring and 360 degree of rotatable connection rings, and tail end is provided with fixing device；Institute
The circular ring stated drills provided with spill, and ring wall is provided with micromachine；The flabellum that described flabellum is installed for stand alone type, and
And the bottom of flabellum is provided with the drive link with gear wheel；Support is fixed by the spill drilling on circular ring in drive link,
The gear wheel of drive link is meshed with the little gear at the rotating shaft end of micromachine, twice of the Zhou Changwei little gears of gear wheel, small
The circumference of pinion rotation one, gear wheel just rotate semi-circumference, and flabellum just with drive rod rotation, forms the angular transformation of 180 degree, entered
And to make fan wind-force size with angle change by the conversion of coordinated signals fan blade angles to change；Described control system
Single-chip microcomputer provided with control motor forward/backward rotation and rotating speed, control motor turns to and rotating speed.
Described support frame for fan is two concave supports, and the fixing end of support is separately mounted to fixing device and 360
In the fixing end of degree rotatable connection ring；And front and rear sides are respectively equipped with an infrared inductor.
Temperature sensor is additionally provided with described support frame for fan, the control system is provided with the frequency conversion being connected with motor
Device.
360 degree of described rotatable connections are equipped with 360 degree of switching line apparatus of collar-shaped.
Rotatable 45 degree of change is respectively provided with described two concave supports, with fixing end to 45 degree of external expansion, shape
Into using two supports in central shaft as 90 degree, be respectively 45 degree of equilateral right angled triangle architecture mode with ground.
360 degree of switching line apparatus of the terminals of described micromachine and a collar-shaped are connected.
The spill area of described spill drilling is bonded a plastics briquetting and flabellum is fixed.
Two described concave supports are rectangle female bracket, after staying enough sufficient spaces to fan shield, in support
One is bonded respectively the identical docking of bottom plate realization that bottom plate both sides out flip out may be reversed, and two supports form one
Complete triangle support frame.The function key that substrate out is provided with fan functionality may be reversed.
The present invention design principle be：
Independent one-piece construction flabellum is installed, while the rotation direction of motor changes, the structure of flabellum also changes therewith, enters
And cause the wind effect that is more suitable for, and and by infrared inductor, person body orientation is identified, by fan automatic decision, with
The wind direction of Shi Fanzhuan fans.
Change of the wind：By can control the single-chip microcomputer of motor reversal to control motor to turn to so that change the wind direction of fan
Changeabout wind direction.
Wind-force is adjusted：The temperature collected by temperature sensor feeds back to single-chip microcomputer through control system, when temperature is less than
During human body preference temperature, single-chip microcomputer is the instruction feedback of wind-force is turned down to control system, and control system is by controlling frequency converter control
Motor speed processed turns wind-force, slow down air mobility down, in case temperature decline is too fast；Otherwise when temperature is too high, control system
System control inverter control motor rotating speed tunes up wind-force, accelerates air flow property, accelerates temperature and declines, it is suitably warm to reach human body
Degree.
Fan main body structural change form is：In flabellum installation place, add a circular ring that can be arranged on motor,
Accomplish that flabellum need not be directly installed on above the rotary shaft of motor, adapter ring direction obtains flabellum toward extension among motor
The effect that may be among motor, and then it is all the positive aesthetic feeling of fan make it that fan both sides look at.
Changeable-shaped blade structure designs：The flabellum that described flabellum is installed for stand alone type, and the bottom of flabellum is provided with
Drive link with gear wheel；Support is fixed by the drilling of spill on circular ring in drive link, the gear wheel of drive link and
The little gear at the rotating shaft end of micromachine is meshed, twice of the Zhou Changwei little gears of gear wheel, the circumference of pinion rotation one, greatly
Gear just rotates semi-circumference, and flabellum just with drive rod rotation, forms the angular transformation of 180 degree, and then cause by the control that links
Fan blade angles conversion processed, positive air-supply effect is completely transplanted to the back side；
Fan outward appearance：It is all the positive outward appearance of fan that common fan outward appearance, which is made into two sides, obtains positive and negative and sees it is all fan
Positive effect.
Support frame for fan is designed using triangular pattern, both ensures security, also produces the work with certain aesthetic
With.
Advantages of the present invention：
By changing motor rotation direction and rotation to flabellum, the front airflow effects of fan are perfectly converted to wind
The back side is fanned, reaches the functional effect regardless of the positive back side, the position of the human body sensed by infrared inductor, if human body is in wind
Fan air-supply to the back side, control system is by controlling motor to invert, and starts micromachine and carry out fan blade angles change, from
The dynamic backing of the wind for realizing fan, it solves the single wind direction air-out of electric fan, and solves in small space, it is necessary to reversely
, it is necessary to turn the problem of fan is to dry manually when wind direction blows.Simultaneously by control system adjust automatically wind-force size, reach
To human body preference temperature, the rest beneficial to people is slept.
