Meet national standard in order to which comfort level and the condensation of user can be improved, and does not reduce the refrigeration of air conditioner Effect, the embodiment of the invention provides a kind of control method of air conditioner, this method can be applied to the sky of laterally single wind deflector It adjusts in device, and the air conditioner is not installed with humidity sensor.As shown in Fig. 2, this method may include:
201, after the first preset time period of operation refrigeration mode or dehumidification mode, the humidity ginseng in current period is obtained Number.
Wherein, wind deflector can be gone to maximum upper limit angle when running refrigeration mode or dehumidification mode by air conditioner At position, to avoid condensation is generated.After running the first preset time period, household air-conditioner is stablized, and can periodically adjust The angle of whole wind deflector, is illustrated by taking a cycle as an example herein.Air conditioner can first obtain the ginseng of the humidity in current period Number, the humidity parameter are parameter relevant to indoor relative humidity, specifically may include: room temperature, evaporating temperature, pressure The running frequency of contracting machine and the wind speed of indoor fan.Wherein, evaporating temperature can be by the temperature sensing installed in indoor coil Device obtains.
202, according to humidity parameter, corresponding humidity factor is determined.
Wherein, air conditioner, can be using the formula prestored: T=after getting the humidity parameter in current period (T1Base-T1)+(T2-T2Base)+KF*(F-FBase), determine corresponding humidity factor T, the unit of T is DEG C.Wherein, T1BaseTo preset room Interior temperature, T1 are the room temperature in current period, and T2 is the evaporating temperature in current period, T2BaseFor preset and current week The corresponding evaporating temperature of wind speed in phase, KF are preset coefficient of frequency corresponding with wind speed, and F is the compressor in current period Running frequency, FBaseFor preset running frequency corresponding with wind speed.In concrete implementation, T2BaseAnd FBaseRefer to mark cold house Under interior operating condition, indoor dry-bulb temperature is 27 DEG C, and wet-bulb temperature is 19 DEG C, when relative humidity is 47.5% corresponding evaporating temperature and Running frequency, at this point, T1BaseIt is 27 DEG C.And T2Base、FBaseIt with KF is codetermined by the type of air conditioner and the wind speed of indoor fan 's.
It should be noted that in embodiments of the present invention, formula T=(T1Base-T1)+(T2-T2Base)+KF*(F-FBase) it is pre- First tested.Can be obtained by the formula: humidity factor is bigger, and indoor relative humidity is bigger, be because of are as follows: Fig. 3 is sky Evaporating temperature when gas water capacity, refrigeration or dehumidifying, the relational graph between the relative humidity of indoor environment respectively, such as Fig. 3 institute Show, relative humidity and air humidity content are at linear function, and evaporating temperature and relative humidity, at linear function, relative humidity is got over Height, evaporating temperature are higher, that is to say, that relative humidity and T1Base- T1 is positively correlated.Fig. 4 is the pass of evaporating temperature and room temperature System's figure, as shown in figure 4, with the increase of room temperature, evaporating temperature approximately linear increases under same relative humidity, that is, Say, evaporating temperature is positively correlated with room temperature, and since relative humidity and evaporating temperature are positively correlated, relative humidity with Room temperature, i.e. (T2-T2Base) be positively correlated.Fig. 5 is the relational graph of the running frequency of evaporating temperature and compressor, such as Fig. 5 institute Show, identical in relative humidity, room temperature is identical, and in the identical situation of the wind speed of indoor fan, evaporating temperature is with operation frequency The raising of rate and reduce, that is to say, that evaporating temperature is negatively correlated with running frequency, but due to relative humidity and evaporating temperature at It is positively correlated, therefore relative humidity and running frequency, i.e. (F-FBase) be negatively correlated.After comprehensively considering and being tested, obtain opposite Humidity and (T1Base-T1)+(T2-T2Base)+KF*(F-FBase) be positively correlated, phase is characterized using humidity factor in the embodiment of the present invention To the size of humidity, therefore relative humidity is bigger, and humidity factor is bigger.
203, according to humidity factor, the upper limit angle for the upper limit position and zero degree position that wind deflector can be swung is determined.
Wherein, be located at due to wind deflector outside the air outlet of indoor unit, inside and outside temperature it is different, be also easy to produce solidifying Dew.When the relative humidity of indoor environment is higher, (dew-point temperature refers to that the vapor in air becomes to corresponding dew-point temperature Temperature when dewdrop) it is higher, so that (evaporating temperature refers to liquid gasification for dew-point temperature and the evaporating temperature of indoor machine evaporation When temperature) difference it is bigger, more the easy outer surface of machine indoors generates condensation.In conjunction with the dew-point temperature and evaporating temperature in Fig. 3 Difference and relative humidity relational graph shown in, when relative humidity be lower than 30% when, the difference of dew-point temperature and evaporating temperature is Negative value shows that indoor unit outer surface will not generate condensation;When relative humidity is higher than 30%, the difference of dew-point temperature and evaporating temperature Value is greater than zero, and relative humidity is higher, and difference is bigger, shows that indoor unit outer surface is more also easy to produce condensation.Therefore solidifying in order to meet The national standard of dew, can be by the larger of the upper limit angle setting that wind deflector of relative humidity when higher can be swung, will be relatively wet The upper limit angle that wind deflector when spending lower can be swung is arranged smaller.
Again due to the increase with refrigeration or the runing time of dehumidifying, the relative humidity of indoor environment can be gradually reduced, when It is indoor very low without moisture removal or moisture removal when relative humidity is lower, that is to say, that relative humidity reduces to a certain extent (usually It is 50% ± 10%) it keeps stablizing afterwards, as shown in Figure 6.
In conjunction with Fig. 3 and Fig. 6, the relative humidity of available upper limit angle and indoor environment, i.e. humidity factor is positively correlated, As shown in Figure 7.
According to the relationship of Fig. 7, upper limit angle can be associated in advance with humidity factor, and be prestored in air conditioner Limit the relationship of angle and humidity factor.In this way, air conditioner is after determining the humidity factor in current period, it can basis The relationship prestored determines that the upper limit angle for the upper limit position and zero degree position that wind deflector can be swung, the zero degree position are wind deflector Position when being closed completely.
Specific: if humidity factor is less than or equal to the first preset temperature, air conditioner can be pre- by prestore first If angle is determined as upper limit angle;If humidity factor is greater than or equal to second preset temperature, air conditioner can will be prestored Second predetermined angle is determined as upper limit angle, and the second predetermined angle is greater than the first predetermined angle;If humidity factor is greater than first Preset temperature and less than the second preset temperature, then air conditioner can be by appointing within the scope of the first predetermined angle and the second predetermined angle One angle is determined as upper limit angle.In one possible implementation, if humidity factor is greater than the first preset temperature and small In the second preset temperature, then air conditioner can use formula:Determine upper limit included angle A;Wherein, A Greater than the first predetermined angle and less than the second predetermined angle, A1 is the first predetermined angle, and A2 is the second predetermined angle, T4 second Preset temperature, T3 are the first preset temperature, and T is the humidity factor in current period.Certainly, for other formula, if met The following conditions: as humidity factor reduces, upper limit angle also reduces;When the range of humidity factor is the first preset temperature and second When between preset temperature, the upper limit angle obtained using the formula between the first predetermined angle and the second predetermined angle, then The formula is also in the protection scope of the embodiment of the present invention.
It should be noted that after air conditioner determines upper limit angle, wind deflector can be swung at this time angular range are as follows: the upper limit Between angle and lower limit angle, lower limit angle refers to the lower position that wind deflector can be swung.Fig. 8 is wind deflector and zero degree position The schematic diagram of angle, as shown in Figure 8, it is assumed that lower limit angle is B, and upper limit angle is A, then B is greater than A, the swing model of wind deflector It is trapped among between A to B.Fig. 9 is wind deflector in different location, the lower envelope line schematic diagram of outlet air, under wherein upper limit position is corresponding Envelope 1, lower position correspond to lower envelope line 2, and as shown in Figure 9, the angle of wind deflector and zero degree position is smaller, lower envelope line Position is higher, and the chance for blowing to human body at this time is smaller, and is obtained at upper limit position according to test, any position of lower envelope line All it is higher than 1.8 meters, cold human body not blown by the wind.
If 204, upper limit angle was less than the upper limit angle in a upper period, controls wind deflector and go to mesh in current period At the corresponding position in ticket holder angle.
Wherein, air conditioner, can be by the upper limit angle and upper one week after determining the upper limit angle in current period Interim upper limit angle is compared.If identical, keep the angle of wind deflector constant in current period.If the upper limit Angle was less than the upper limit angle in a upper period, then air conditioner can control wind deflector and go to target angle pair in current period At the position answered, which obtained according to the upper limit angle in current period and the lower limit angle of fixation.
In concrete implementation, air conditioner may include that N number of wind deflector swings gear, upper limit angle and lower limit can be pressed from both sides Hunting range between angle is divided equally, so that each gear corresponds to an angle.The preset gear of air conditioner or user are selected The gear selected corresponds to target angle as target gear, target gear, and when upper limit angle changes, air conditioner can basis Upper limit angle and lower limit angle after variation recalculate target angle, and wind deflector is gone to the corresponding position of target angle Place.
It should be noted that in embodiments of the present invention, air conditioner can repeat step 201- step 204, in this way, With the increase of running time, indoor relative humidity reduces, upper limit angle becomes smaller, and human body is not easy to be blown to by cold wind, improves Users'comfort.
Illustratively, it is assumed that the first preset temperature T3 is 0 DEG C, and the first predetermined angle A1 is 20 °, and the second preset temperature T4 is 3 DEG C, the second predetermined angle A2 is 45 °, and lower limit angle is 95 °, then when the humidity factor T in current period is 3 DEG C, air conditioner Determine that upper limit angle is 45 °, the angular range that wind deflector can be swung at this time are as follows: 45 ° to 95 °.After operation ten minutes, it is assumed that Humidity factor T in current period is 1.5 DEG C, and air conditioner can determine that upper limit angle is 32.5 °, and wind deflector can be swung at this time Angular range are as follows: 32.5 ° to 95 °.
Further, the present invention can be realized anti-blow-through or calm sense function.Specifically, air conditioner is in operation refrigeration mode Or when dehumidification mode, if receiving the calm sense instruction of user, air conditioner can first judge refrigeration mode or dehumidification mode Runing time whether reach the first preset time period.If not up to, wind deflector can be gone to maximum upper limit angle, i.e., At the position of second predetermined angle, to avoid condensation is generated.When reaching the first preset time period between at runtime, household air-conditioner Stablize, according to the corresponding humidity factor of current humidity parameter, can determine upper limit position and the zero degree position of corresponding wind deflector The first angle set, and control wind deflector and go at the corresponding first position of first angle.First position is gone in wind deflector After second preset time period, air conditioner can redefine the upper limit position of wind deflector and the second angle of zero degree position, if the Two angles are identical as first angle, then wind deflector is maintained at constant at first position, reacquire after the second preset time period Humidity parameter;If second angle is less than first angle, wind deflector can be gone at the corresponding upper limit position of second angle, and After wind deflector goes to the second preset time period of the position, upper limit angle is redefined, until the upper limit angle is first pre- If until angle.If having reached the first preset time period, current humidity parameter can be directly acquired, determines corresponding humidity The factor, and adjust upper limit angle.In this way, humidity factor is determined, dynamically to adjust the upper limit by periodically obtaining humidity parameter It is blown at this time until upper limit angle is minimum less than human body position.
Illustratively, according to above example, it is assumed that when receiving calm sense instruction, refrigeration mode or dehumidification mode Runing time has reached the first preset time period, and humidity factor at this time is 4 DEG C, it is determined that upper limit angle is 45 °, and by wind-guiding Plate is gone at 45 ° of positions.It is corresponding if the humidity factor that air conditioner determines is 3 DEG C after the second preset time period 5 minutes Upper limit angle is still 45 °, then keeps wind-guiding Board position constant.If it is determined that humidity factor be 1.5 DEG C, then air conditioner can use Formula A=20+ (45-20) (1.5-0)/(3-0)=32.5 °, calculating upper limit angle are 32.5 °, and wind deflector is gone to from 45 ° At 32.5 ° of position.In this way, the upper limit angle of wind deflector also subtracted accordingly every 5 minutes as humidity factor gradually decreases It is small, until being decreased to 20 °.
For another example assume to instruct receiving calm sense, and the runing time of refrigeration mode or dehumidification mode has reached the When one preset time period, determining humidity factor is 0 DEG C, then the upper limit angle that air conditioner determines is 20 °, and control wind deflector is gone to At 20 ° of positions.A determining humidity factor every five minutes, if humidity factor is always less than or equal to 0 DEG C, wind deflector is always It is maintained at 20 ° of position, realizes calm sense function.
The control method of air conditioner provided by the invention, in the first preset time period of operation refrigeration mode or dehumidification mode Afterwards, the humidity parameter obtained in current period determines corresponding humidity factor according to humidity parameter, according to humidity factor, determines The upper limit angle of upper limit position and zero degree position that wind deflector can be swung, if the upper limit angle was less than the upper limit folder in a upper period Angle then controls wind deflector and is gone at the corresponding position in target angle in current period, target angle according to the upper limit angle and Lower limit angle obtains.In this way, by the way that the upper limit position of wind deflector and the upper limit angle of zero degree position is associated with humidity factor, Upper limit angle is determined according to the humidity factor in current period, since humidity factor is obtained according to humidity parameter, each Humidity parameter is associated with indoor relative humidity, therefore with the increase of running time, indoor relative humidity gradually drops It is low, it can be become smaller according to the upper limit angle that humidity factor determines, i.e., the upper limit angle in current period can be less than in a upper period Upper limit angle realizes while the national standard for meeting condensation so that human body is not easy to be blown to by cold wind, improves use The comfort level at family.
