In order to avoid user is unable to reach the purpose of user's cooling, and the blowing because of fan because the blowing of fan is too small
Excessive the problem of causing user to feel not quite the thing.The embodiment of the present disclosure provides firstly a kind of control method for fan, such as Fig. 1 institutes
Show, may comprise steps of：
In step s 110, whether during fan running, detecting in the blowing region of fan has target object.
In the embodiments of the present disclosure, it can be domestic fan, can also be Industrial fan lamp, it, can by taking domestic fan as an example
To be divided into：Ceiling fan, desk fan, stand fan and wall fan etc..Air motion is formed during fan running, is generated to blowing region
Certain air quantity.
Target object can be people, can also be other objects.Illustratively, if target object is people, in wind
Fan in operation process, can be detected by the modes such as infrared in the blowing region of fan whether someone.Wherein, people is in blowing region
It can be movable, can also be static, not influence to detect.
In addition, target object can also be other objects, such as animal.Illustratively, if fan is located in chicken farm,
The target object can be the chicken supported in chicken farm.Fan can provide cooling and draught effect for the chicken supported in chicken farm.It can
Whether in a manner of also with infrared detection, detecting in the blowing region of fan has chicken.
If detecting in blowing region there is target object, in the step s 120, detect between fan and target object
Current distance.
After there is target object in the blowing region for detecting fan, should also it detect current between fan and target object
Distance, in order to which fan makes adjustment appropriate according to current distance.It is artificial example with target object, indoors in environment, by
In people often in there is multiple people in active state or room, and everyone is with a distance from fan when difference, then working as fan
When being blowed using same blowing pattern, the closer people's blowing of the fan that certainly will adjust the distance is excessive, and adjusts the distance fan farther out
People's blowing is too small, or can only meet the blowing amount size of the people apart from fan certain distance.Therefore, it is necessary to according to fan with it is more
Current distance between people carrys out the appropriate blowing amount for adjusting fan, to meet the different blowing demands of more people.When interior only one
It, can be according to the distance between fan and the user constantly adjustment air quantity, to meet the blowing need appropriate of the user when personal
It asks.
In step s 130, according to current distance, fan unit in the predeterminable area range towards target object is controlled
The air quantity generated in time.
It is artificial example with target object, indoors in environment, according to the size of blowing amount, conventional fan control pattern one
As fan is divided into several class, and as needed can be with yaw or not yaw.When fan is operated and put in a certain class
When head, if one-man in room, when people is closer apart from fan, what fan generated on the person in the unit interval
Air quantity, compared to people apart from fan farther out when, the air quantity that fan generates on the person in the unit interval is big.It blows in this way and causes fan
User constantly go as needed adjustment fan blowing size, or endure fan blowing it is excessive or too small, to user with
Carry out the discomfort of body.
Therefore, it is necessary to when people is closer apart from fan, control fan to reduce the air quantity generated in the unit interval on the person,
When people apart from fan farther out when, control fan increases the air quantity that is generated in the unit interval on the person.
Furthermore it is also possible to detect and according to information such as indoor temperature, humidity, between fan and the target object
On the basis of current distance, increase or decrease what fan generated in the predeterminable area range towards target object in the unit interval
Air quantity.Illustratively, when indoor temperature is 30 DEG C, in predeterminable area range of the fan at pre-determined distance towards target object
The air quantity generated in unit interval is 200m3/ min, then when temperature is increased to 35 DEG C indoors, by fan at pre-determined distance
The air quantity generated in towards the unit interval in the predeterminable area range of target object increases to 250m3/min。
It should be appreciated that in the embodiment of the present disclosure, the air quantity of fan increases and decreases, and refers to the wind that fan outlet generates
Amount, the air force gone out by adjusting fan outlet reach wind of the control at a certain distance from target object region
Measure size.
If detected in blowing region without target object, in step S140, keep the operating condition of fan constant.
It according to the actual needs,, can in order to maintain the circulation of air if detected in blowing region without target object
To keep the operating condition of fan constant；It can also be according to advance setting, for power saving, when fan is after operating a period of time
When can not still detect target object, the operating for closing the fan can be selected, or the running power of the fan is reduced.
The control method for fan provided in the embodiment of the present disclosure can detect the blowing of fan during fan running
Whether there is user in region, if there is user, detects the current distance between fan and user, can be adjusted according to current distance
The air quantity that fan is generated in the unit interval towards user region be increase or reduce, can to avoid user blowing because of fan
Wind is too small and is unable to reach the purpose of user's cooling, can also avoid causing user to feel not quite the thing because the blowing of fan is excessive
The problem of.
In order to preferably control the air quantity that fan generates in the predeterminable area range towards target object in the unit interval,
As the refinement of Fig. 1 methods, in another embodiment of the present disclosure, as shown in Fig. 2, step S130 may comprise steps of：
In step S210, judge whether current distance is more than predetermined threshold value.
After detecting the current distance between fan and target object, by between fan and target object it is current away from
It is compared from pre-set predetermined threshold value.Wherein, predetermined threshold value can there are one, it is possibility to have it is multiple.For basis
Current distance between fan and target object, the adjustment fan more refined is in the predeterminable area range towards target object
Predetermined threshold value can be arranged with better meeting the user experience of user for the air quantity variable quantity generated in the middle unit interval
It is The more the better to be multiple, and according to the actual needs.
Illustratively, table 1 gives the current distance between fan and target object, with fan towards target object institute
Regional extent in relation table between the air quantity that generates in the unit interval.
Table 1
It should be noted that the correspondence numerical value between the current distance that table 1 provides and air quantity is only exemplary, specifically may be used
To be set according to the actual needs.
Furthermore it is also possible to be associated with temperature and humidity, illustratively, when environment temperature is 30 DEG C, table 1 may be used,
It is assumed that target object is 200m in the air quantity experienced at fan 2m3/ min is most appropriate, then when environment temperature is 35
DEG C when, can be on the basis of table 1, corresponding air quantity all increases to 50m3/ min, to meet the suitability degree of target object.
If current distance is more than predetermined threshold value, in step S220, control fan is towards the area where target object
The air quantity generated in the unit interval in the range of domain increases.
When predetermined threshold value has multiple, and fan is when starting running, according to the actual needs, can set one it is initial
Operating parameters according to predetermined threshold value be illustratively the air quantity generated corresponding to 3m by the initial operation of fan in conjunction with table 1
It is operated, i.e., in the regional extent where the target object when forefan to direction apart from the regions fan 3m in the unit interval
Generated air force is 250m3/ min, if detecting the current distance 4m of fan and the target object at this time, i.e., currently
Distance is more than predetermined threshold value, then at control fan distance objective object 4m, towards list in the regional extent where target object
The air quantity generated in the time of position increases to 300m3/min。
If current distance is less than or equal to predetermined threshold value, in step S230, control fan is towards where target object
Regional extent in the air quantity that generates in the unit interval reduce.
When predetermined threshold value has multiple, and fan is when starting running, according to the actual needs, can set one it is initial
Operating parameters according to predetermined threshold value be illustratively the air quantity generated corresponding to 3m by the initial operation of fan in conjunction with table 1
It is operated, then when the unit interval in the regional extent where target object of the forefan to direction apart from the regions fan 3m
Air force caused by interior is 250m3/ min works as if detecting the current distance 2m of fan and the target object at this time
Front distance is more than predetermined threshold value, then what control fan generated in the regional extent towards where target object in the unit interval
Air quantity is reduced to 200m3/min。
It should be noted that in conjunction with table 1, if the current distance between fan and target object and in table 1 is not preset
Current distance it is corresponding, in conjunction with step S210, such as the current distance between fan and target object is 2.4m, then selecting 2m
Corresponding air quantity 200m3/min.If the current distance between fan and target object is 2.5m, can select to work as in fan
Preceding fan is adjusted to the air quantity 200m3/min corresponding to 2m, can also select by the current air quantity of fan be adjusted to 3m institute it is right
The air quantity 250m3/min answered, can specifically be carried out in conjunction with parameter informations such as temperature and humidities in current environment appropriate selection and
Adjustment.Involved in embodiment to current distance without and preset table in distance completely to it is corresponding when can take the measure,
Therefore, for convenience's sake, no longer this is repeated in following embodiments.
In order to which diversification controls the air quantity that fan generates in the predeterminable area range towards target object in the unit interval,
As the refinement of Fig. 1 methods, in the another embodiment of the disclosure, as shown in figure 3, if rotation speed of the fan is unadjustable, and
The oscillating fan rate is adjustable, and step S130 can also include the following steps：
In step S310, the current yaw rate of fan is detected.
The yaw rate of fan can be the angle of fan yaw per second, i.e. the angular speed of the oscillating fan.
In step s 320, judge whether current distance is more than predetermined threshold value.
Illustratively, table 2 gives current distance between fan and target object, the angular speed of oscillating fan and in court
Correspondence between the air quantity generated in the unit interval into the predeterminable area range of the target object.
Table 2
In conjunction with table 2, if the initial yaw rate of fan is π/6 (rad/s), corresponding predetermined threshold value is 2m, will
Current distance between fan and target object is compared with predetermined threshold value 2m.
If current distance is more than predetermined threshold value, in step S330, according to current yaw rate lookup corresponding first
Default yaw rate.
In conjunction with step S320, if the current distance between fan and target object is 3m, can be obtained in look-up table 2,
Yaw rate corresponding to 3m is π/8 (rad/s).
In step S340, current yaw rate is reduced to the first default yaw rate by control fan.
In conjunction with above-mentioned steps S340, π/8 (rad/s) will be reduced to by π/6 (rad/s) when the yaw rate of forefan.
If current distance is less than or equal to predetermined threshold value, corresponding according to current yaw rate lookup in step S350
Second default yaw rate.
In conjunction with step S320, if the current distance between fan and target object is 1m, can be obtained in look-up table 2,
Yaw rate corresponding to 1m is π/4 (rad/s).
In step S360, current yaw rate is increased to the second default yaw rate by control fan.
In conjunction with above-mentioned steps S350, π/4 (rad/s) will be increased to by π/6 (rad/s) when the yaw rate of forefan.
It should be noted that in the embodiment that the disclosure provides, by changing the yaw rate of fan, to adjust fan court
The air quantity generated in the unit interval into the predeterminable area range of target object, the air quantity are an average value.For example, if one
In personal environment indoors, cooling is blowed in the air quantity generated using fan, in the oscillating fan and the constant situation of wind speed
Under, if position of this people before fan is constant, fan was swung according to specific yaw rate, such as at 5 minutes
Time in, the time in wind to this person that fan generates is 3 minutes in total, since oscillating fan is without by wind
Time with to the people is 2 minutes in total, then should by fan in the predeterminable area range towards target object unit
The air quantity generated in time, is interpreted as：Fan averagely blows to the average air quantity in the people's body in 5 minutes, and is not intended to be
The air quantity for referring to 3 minutes in the wind to this person that fan generates, by changing the yaw rate of fan, reaching can be with
The purpose that fan blows to the air quantity with human body in average time is adjusted, to meet the blowing cooling demand of user so that fan
Human body will not be caused excessively to dry.
In order to which diversification controls the air quantity that fan generates in the predeterminable area range towards target object in the unit interval,
As the refinement of Fig. 1 methods, in the another embodiment of the disclosure, as shown in figure 4, if rotation speed of the fan is adjustable, and should
Oscillating fan rate is unadjustable, and step S130 can also include the following steps：
In step S410, the current rotating speed of fan is detected.
Under normal circumstances, the wind that fan generates is to drive the flowing of air to form air-flow by the rotor rotation in fan,
To generating certain air quantity in the unit interval in the predeterminable area range towards target object.Fan is by rotor, stator and control
Circuit forms, wherein rotor is made of magnet, flabellum and axis；Stator is made of silicon steel sheet, coil and bearing；Control circuit by
The poles induced magnet N.S. IC are excitatory inside generation via the conducting of its coil of circuit control to make rotor rotate.
In the step s 420, judge whether current distance is more than predetermined threshold value.
Illustratively, table 3 gives current distance between fan and target object, the rotating speed of fan and described in
Correspondence between the air quantity generated in the unit interval in the predeterminable area range of target object.
Table 3
The rotating speed of fan refers to the number of turns that fan rotates within the unit interval, with the number of turns of rotation per second is single in embodiment
Position, i.e., (r/min).
In conjunction with table 3, if the stabilized (steady-state) speed of fan initial rotation is rotated according to 2500r/min, the rotating speed pair
The predetermined threshold value answered is 2m, and the current distance that can be detected between fan and target object is compared with predetermined threshold value 2m.
If current distance is more than predetermined threshold value, in step S430, it is default to search corresponding first according to current rotating speed
Rotating speed.
In conjunction with step S420, if current distance between fan and target object is 3m, by table look-up 3 it is found that
The corresponding rotation speed of the fan of 3m should be 3000r/min.
In step S440, current rotating speed is increased to the first preset rotation speed by control fan.
Therefore, in conjunction with step S430,3000r/min will be increased to from rotating speed 2500r/min is set when the rotating speed of forefan.
If current distance is less than or equal to predetermined threshold value, in step S450, corresponding second is searched according to current rotating speed
Preset rotation speed.
In conjunction with step S420, if current distance between fan and target object is 1m, by table look-up 3 it is found that
The corresponding rotation speed of the fan of 1m should be 2000r/min.
In step S460, current rotating speed is reduced to the second preset rotation speed by control fan.
Therefore, in conjunction with step S450,2000r/min will be reduced to from rotating speed 2500r/min is set when the rotating speed of forefan
It is generated in the unit interval in the predeterminable area range towards target object for more diversified control fan
Air quantity, as the refinement of Fig. 1 methods, in the another embodiment of the disclosure, as shown in figure 5, if rotation speed of the fan is adjustable, and
And the oscillating fan rate is also adjusted, step S130 can also include the following steps：
In step S510, the current rotating speed of fan and current yaw rate are detected respectively.
In step S520, judge whether current distance is more than predetermined threshold value.
If current distance is more than predetermined threshold value, in step S530, it is default that corresponding third is searched according to current rotating speed
Rotating speed, and yaw rate is preset according to the corresponding third of current yaw rate lookup.
In step S540, current rotating speed is increased to third preset rotation speed by control fan, and controlling fan will be current
Yaw rate is reduced to third and presets yaw rate.
If current distance is less than or equal to predetermined threshold value, in step S550, the corresponding 4th is searched according to current rotating speed
Preset rotation speed, and according to the corresponding 4th default yaw rate of current yaw rate lookup.
In step S560, current rotating speed is reduced to the 4th preset rotation speed by control fan, and controlling fan will be current
Yaw rate increases to the 4th default yaw rate.
In conjunction with above-mentioned steps S310 to step S360 and step S410 to step S460, illustratively, table 4 gives
The rotating speed of current distance, fan between fan and target object, the yaw rate of fan and towards the target object
