Step S11 at least one of is washed and is washed cleaning way cleaning with frost when air conditioner enters automatically cleaning mode Evaporator.
In the present embodiment, air conditioner 100 can be preset and add up refrigerating operaton time H0 (for example, H0=240 is small When) after need enter automatically cleaning mode, i.e., the default scavenging period period of the air conditioner 100 be H0.When the accumulative refrigeration of air conditioner 100 When running h hours (h >=H0), which meets the self-cleaning condition that needs, and controller 110 controls automatically cleaning warning light It lights, user can control air conditioner 100 by remote controller key and open automatically cleaning mould after the automatically cleaning warning light lights Formula.
In the present embodiment, frost, which is washed, refers to being melted into water in 130 surface frosting of evaporator by frost and taking away evaporator The dust on 130 surfaces, to achieve the purpose that clean evaporator 130;Washing refers to generating by 130 surface of evaporator cold Condensate takes away the dust on 130 surface of evaporator, to achieve the purpose that clean evaporator 130.
It is appreciated that the application single can clean the evaporator 130 using the white cleaning way washed or washed, it can also Two kinds of cleaning ways are washed and washed using frost and clean the evaporator 130, wherein mainly to wash and wash using frost in the present embodiment For two kinds of cleaning ways, the cleaning process of evaporator 130 is illustrated.As shown in figure 3, step S11 includes following son Step:
Sub-step S111 controls the surface frosting of evaporator.
In the present embodiment, sub-step S111 may include: in cooling mode, according in the air conditioner 100 Machine coil pipe actual temperature adjusts the aperture of the electric expansion valve 150 and/or the frequency of the compressor 140, so that in described Machine coil pipe actual temperature is less than or equal to first object temperature;It is less than or equal to described first in the interior machine coil pipe actual temperature When target temperature, controls the air conditioner 100 and run the first preset time, so that the surface frosting of the evaporator 130.
Wherein, when the interior machine coil pipe actual temperature is greater than the first object temperature, the electric expansion valve is reduced 150 aperture, so that the interior machine coil pipe actual temperature is less than or equal to first object temperature;When the electric expansion valve 150 Aperture when being reduced to the first default aperture, if the interior machine coil pipe actual temperature is still greater than the first object temperature, rise The frequency of the high compressor 140, until the interior machine coil pipe actual temperature is less than or equal to the first object temperature.
Specifically, when the surface of evaporator 130 needs frosting, controller 110 controls the operation refrigeration mould of air conditioner 100 Formula, it is assumed that the first object temperature is T1 (value range of T1 can be -12 DEG C~-10 DEG C, preferably -10 DEG C), electronic expansion The aperture of valve 150 is A1 (value range of A1 can be 60pls~100pls, initial value 100pls), the frequency of compressor 140 Rate is B1 (value range of B1 can be 50Hz~60Hz, initial value 50Hz), and controller 110 obtains coil temperature in real time and passes The interior machine coil pipe actual temperature T that sensor 160 is fed back, and according to interior machine coil pipe actual temperature T to the aperture A1 of electric expansion valve 150 Or the frequency B1 of compressor 140 is adjusted, so that interior machine coil pipe actual temperature T meets: T≤T1.
For example, controller 110 can reduce the aperture A1 of electric expansion valve 150 since initial value as T > T1, when When the aperture A1 of electric expansion valve 150 is reduced, interior machine refrigerant pressure is reduced, and evaporating temperature decreases, so that interior machine coil pipe is real Border temperature T≤T1;When the aperture A1 of electric expansion valve 150 is reduced to 60pls (the default aperture of i.e. above-mentioned first) that can not still expire When sufficient T≤T1, then controller 110 starts to adjust the frequency B1 of compressor 140, and the frequency B1 of compressor 140 is opened from initial value Begin to increase, when the frequency B1 of compressor 140 is increased, can also reduce interior machine refrigerant pressure, thus the practical temperature of machine coil pipe in reducing T is spent, so that interior machine coil pipe actual temperature T meets T≤T1.It is understood that when the interior machine coil pipe that controller 110 obtains is practical When temperature T meets T≤T1, then the aperture A1 of electric expansion valve 150 is constant, and the frequency B1 of compressor 140 is also constant.
When interior machine coil pipe actual temperature T meets T≤T1, it is practical in interior machine coil pipe that controller 110 need to control air conditioner 100 The first preset time X1 is run in the state of temperature T≤T1, so that the surface frosting of evaporator 130.Wherein, this first it is default when Between the value range of X1 can be 8min~10min.
Sub-step S112, the frost controlled on evaporator melt.
In the present embodiment, after the completion of the surface frosting of evaporator 130, controller 110 need to control 130 surface of evaporator Frost melt.Sub-step S112 may include: in cooling mode, according to the practical temperature of the interior machine coil pipe of the air conditioner 100 Degree adjusts the aperture of the electric expansion valve 150 and/or the frequency of the compressor 140, so that the practical temperature of the interior machine coil pipe Degree is greater than or equal to the second target temperature;When the interior machine coil pipe actual temperature is greater than or equal to second target temperature, It controls the air conditioner 100 and runs the second preset time, so that the frost on the evaporator 130 melts.
Wherein, when the interior machine coil pipe actual temperature is less than second target temperature, the electric expansion valve is increased 150 aperture, so that the interior machine coil pipe actual temperature is greater than or equal to second target temperature;When the electric expansion valve When 150 aperture is increased to the second default aperture, if the interior machine coil pipe actual temperature still less than second target temperature, The frequency for reducing the compressor 140, until the interior machine coil pipe actual temperature is greater than or equal to second target temperature.
Specifically, when evaporator 130 enters defrost process, air conditioner 100 still runs on refrigeration mode, it is assumed that this second Target temperature is T2 (value range of T2 can be 8 DEG C~12 DEG C, preferably 10 DEG C), and the aperture of electric expansion valve 150 is A2 (A2 Value range can be 120pls~240pls, initial value A1, i.e., electric expansion valve 150 when 130 frosting of evaporator finishes Corresponding aperture), the frequency of compressor 140 is that (value range of B2 can be 30Hz~40Hz to B2, initial value B1 steams The corresponding frequency of compressor 140 when hair 130 frosting of device finishes), controller 110 obtains coil temperature sensor 160 in real time and feeds back Interior machine coil pipe actual temperature T, and according to interior machine coil pipe actual temperature T to the aperture A2 or compressor 140 of electric expansion valve 150 Frequency B2 be adjusted so that interior machine coil pipe actual temperature T meet: T >=T2.
For example, controller 110 can increase the aperture A2 of electric expansion valve 150 since initial value as T < T2, work as electricity When the aperture A2 of sub- expansion valve 150 is increased, interior machine refrigerant pressure is increased, and evaporating temperature increases, so that interior machine coil pipe is practical Temperature T >=T2;It is still unable to satisfy when the aperture A2 of electric expansion valve 150 is increased to 240pls (the default aperture of i.e. above-mentioned second) When T >=T2, then controller 110 starts to adjust the frequency B2 of compressor 140, by the frequency B2 of compressor 140 since initial value It reduces, when the frequency B2 of compressor 140 is reduced, can also increase interior machine refrigerant pressure, thus machine coil pipe actual temperature in increasing T, so that interior machine coil pipe actual temperature T meets T >=T2.It is understood that when the practical temperature of interior machine coil pipe that controller 110 obtains When degree T meets T >=T2, then the aperture A2 of electric expansion valve 150 is constant, and the frequency B2 of compressor 140 is also constant.
When interior machine coil pipe actual temperature T meets T >=T2, it is practical in interior machine coil pipe that controller 110 need to control air conditioner 100 The second preset time X2 is run in the state of temperature T >=T2, is finished so that the frost on evaporator 130 melts.Wherein, this is second pre- If the value range of time X2 can be 1min~1.5min.
Sub-step S113, the surface for controlling evaporator generate condensed water.
In the present embodiment, after the frost on evaporator 130 melts, the control evaporator 130 of controller 110 enters cold The process of condensate cleaning.Sub-step S113 may include: in cooling mode, according to the interior machine coil pipe of the air conditioner 100 Actual temperature adjusts the aperture of the electric expansion valve 150 and/or the frequency of the compressor 140, so that the interior machine coil pipe Actual temperature is less than or equal to third target temperature;It is less than or equal to the third target temperature in the interior machine coil pipe actual temperature It when spending, controls the air conditioner 100 and runs third preset time, so that the surface of the evaporator 130 generates condensed water.
Wherein, when the interior machine coil pipe actual temperature is greater than the third target temperature, the electric expansion valve is reduced 150 aperture, so that the interior machine coil pipe actual temperature is less than or equal to the third target temperature;When the electric expansion valve When 150 aperture is reduced to third to preset aperture, if the interior machine coil pipe actual temperature is still greater than the third target temperature, The frequency for increasing the compressor 140, until the interior machine coil pipe actual temperature is less than or equal to the third target temperature.
Specifically, when evaporator 130 enters the process of condensed water cleaning, air conditioner 100 still needs to run on refrigeration mode, Assuming that the third target temperature is T3 (value range of T3 can be 2 DEG C~6 DEG C, preferably 4 DEG C), electric expansion valve 150 is opened Degree is that (value range of A3 can be 100pls~180pls, initial value A2, i.e., electronics when 130 defrost of evaporator finishes to A3 The corresponding aperture of expansion valve 150), the frequency of compressor 140 is that (value range of B3 can be 40Hz~50Hz, initial value to B3 For B2, i.e., the corresponding frequency of compressor 140 when 130 defrost of evaporator finishes), controller 110 obtains coil temperature sensing in real time The interior machine coil pipe actual temperature T that device 160 is fed back, and according to interior machine coil pipe actual temperature T to the aperture A3 of electric expansion valve 150 or The frequency B3 of compressor 140 is adjusted, so that interior machine coil pipe actual temperature T meets: T≤T3.
For example, controller 110 can reduce the aperture A3 of electric expansion valve 150 since initial value as T > T3, when When the aperture A3 of electric expansion valve 150 is reduced, interior machine refrigerant pressure is reduced, and evaporating temperature decreases, so that interior machine coil pipe is real Border temperature T≤T3;When the aperture A3 of electric expansion valve 150 is reduced to 100pls (i.e. above-mentioned third presets aperture) that can not still expire When sufficient T≤T3, then controller 110 starts to adjust the frequency B3 of compressor 140, and the frequency B3 of compressor 140 is opened from initial value Begin to increase, when the frequency B3 of compressor 140 is increased, can also reduce interior machine refrigerant pressure, thus the practical temperature of machine coil pipe in reducing T is spent, so that interior machine coil pipe actual temperature T meets T≤T3.It is understood that when the interior machine coil pipe that controller 110 obtains is practical When temperature T meets T≤T3, then the aperture A3 of electric expansion valve 150 is constant, and the frequency B3 of compressor 140 is also constant.
When interior machine coil pipe actual temperature T meets T≤T3, it is practical in interior machine coil pipe that controller 110 need to control air conditioner 100 Third preset time X3 is run in the state of temperature T≤T3, so that the surface of evaporator 130 forms many condensed waters, thus right Evaporator 130 carries out condensed water cleaning.Wherein, the value range of third preset time X3 can be 4min~6min.
It should be noted that in practical applications, when being cleaned to evaporator 130, can first wash again with condensation frost Water cleaning can also be washed first with frost with condensation washing again, and the application does not do any restrictions to this.
Step S12 obtains the total Water generated in cleaning process after the air conditioner exits the automatically cleaning mode.
In the present embodiment, after evaporator 130 cleans, air conditioner 100 exits automatically cleaning mode, controller 110 The total Water Q that this cleaning process generates is obtained from water ga(u)ge 180.It is appreciated that total Water Q is the water ga(u)ge 180 Enter the water detected in automatically cleaning mode to the period for exiting the automatically cleaning mode from air conditioner 100, may include Frost wash and/or water-washing process in the water that generates, it is related with the cleaning way actually used.
Step S13 determines the next scavenging period period of the evaporator according to the total Water.
In the present embodiment, which can be understood as this evaporator 130 is adjacent between cleaning twice Every the time, when the total Water Q generated in cleaning process is more, show that cleaning effect is better;Total Water Q is fewer, shows cleaning effect Fruit is bad.Therefore, total Water Q is more, then the next scavenging period period determined according to the total Water is longer;This is total Water Q is fewer, then the next scavenging period period determined according to the total Water is shorter.
In other words, controller 110 can judge each cleaning effect of evaporator 130 by total Water Q, When the total Water Q of generation is more, show that the cleaning effect of evaporator 130 is preferable, can be spaced longer time enter it is next Secondary cleaning, thus it is longer according to the next scavenging period period that total Water determines;When the total Water Q of generation is less, show to evaporate The cleaning effect of device 130 is poor, and the time for needing interval shorter enters cleans next time, and then keeps evaporator 130 for a long time Clean state avoids bacteria breed.
Specifically, if the total Water Q meets: Q >=Q0, it is determined that the next scavenging period cycle H of the evaporator 130 =H0, wherein Q0 is default total Water, and H0 is the default scavenging period period;If the total Water Q meets: K1*Q0≤Q < Q0, Then determine next scavenging period cycle H=T1*H0 of the evaporator 130, wherein K1 is the first setting value, and T1 sets for second Definite value;If the total Water Q meets: K2*Q0≤Q < K1*Q0, it is determined that the next scavenging period cycle H of the evaporator 130 =T2*H0, wherein K2 is third setting value, and T2 is the 4th setting value;If the total Water Q meets: K3*Q0≤Q < K2*Q0, Then determine next scavenging period cycle H=T3*H0 of the evaporator 130, wherein K3 is the 5th setting value, and T3 sets for the 6th Definite value;If the total Water Q meets: 0≤Q < K3*Q0, it is determined that the next scavenging period cycle H of the evaporator 130= T4*H0, wherein T4 is the 7th setting value.Wherein, first setting value K1 can be able to be for 0.8, second setting value K2 0.9, third setting value K2 can be able to be for the 0.5, the 4th setting value T2 the 0.6, the 5th setting value K3 can be 0.3, 6th setting value T3 can be able to be 0.1 for the 0.4, the 7th setting value T4.
Optionally, as shown in figure 4, since evaporator 130 is after being washed and/or being washed completion cleaning by frost, surface ratio It is moister, and moist environment many bacteriums easy to breed, therefore after step s 11, which may be used also To include:
Step S101 carries out drying and processing to the evaporator.
In the present embodiment, step S101 may include: in a heating mode, according to the interior machine of the air conditioner 100 Coil pipe actual temperature adjusts the aperture of the electric expansion valve 150 and/or the frequency of the compressor 140, so that the interior machine Coil pipe actual temperature is greater than or equal to the 4th target temperature;It is greater than or equal to the 4th mesh in the interior machine coil pipe actual temperature When marking temperature, controls the air conditioner 100 and run the 4th preset time, to dry the moisture on 130 surface of evaporator.
Wherein, when the interior machine coil pipe actual temperature is less than four target temperature, the electric expansion valve is reduced 150 aperture, so that the interior machine coil pipe actual temperature is greater than or equal to the 4th target temperature;When the electric expansion valve When 150 aperture is reduced to four default apertures, if the interior machine coil pipe actual temperature still less than the 4th target temperature, The frequency for increasing the compressor 140, until the interior machine coil pipe actual temperature is greater than or equal to the 4th target temperature.
Specifically, when carrying out drying and processing to evaporator 130, controller 110 need to cut the operational mode of air conditioner 100 Shift to heating mode, it is assumed that the 4th target temperature is T4 (value range of T4 can be 35 DEG C~45 DEG C, preferably 40 DEG C), electricity The aperture of sub- expansion valve 150 is that (value range of A4 can be 80pls~160pls, initial value A3, i.e. evaporator 130 to A4 Condensed water cleaning corresponding aperture of electric expansion valve 150 when finishing), the frequency of compressor 140 is that (value range of B4 can be with by B4 For 40Hz~60Hz, initial value B3, i.e., the corresponding frequency of compressor 140 when the cleaning of 130 condensed water of evaporator finishes), control Device 110 obtains the interior machine coil pipe actual temperature T that coil temperature sensor 160 is fed back in real time, and according to interior machine coil pipe actual temperature T The frequency B4 of aperture A4 or compressor 140 to electric expansion valve 150 are adjusted, so that interior machine coil pipe actual temperature T meets: T≥T4。
For example, controller 110 can reduce the aperture A4 of electric expansion valve 150 since initial value as T < T4, work as electricity When the aperture A4 of sub- expansion valve 150 is reduced, interior machine refrigerant pressure is increased, and evaporating temperature increases, so that interior machine coil pipe is practical Temperature T >=T4;When the aperture A4 of electric expansion valve 150 is reduced to 80pls (the 4th i.e. above-mentioned default aperture) to be still unable to satisfy T When >=T4, then controller 110 starts to adjust the frequency B4 of compressor 140, and the frequency B4 of compressor 140 is risen since initial value Height, when the frequency B4 of compressor 140 is increased, interior machine refrigerant pressure is increased, thus machine coil pipe actual temperature T in increasing, so that Interior machine coil pipe actual temperature T meets T >=T4.It is understood that when the interior machine coil pipe actual temperature T that controller 110 obtains is full When sufficient T >=T4, then the aperture A4 of electric expansion valve 150 is constant, and the frequency B4 of compressor 140 is also constant.
When interior machine coil pipe actual temperature T meets T >=T4, it is practical in interior machine coil pipe that controller 110 need to control air conditioner 100 The 4th preset time X4 is run in the state of temperature T >=T4, thus the moisture on 130 surface of drying evaporator.Wherein, the 4th is pre- If the value range of time X4 can be 6min~8min.It should be noted that in practical applications, controller 110 can be After air conditioner 100 runs 4min~5min, close compressor 140, then rerun 2min~3min, and is blown using low wind file remaining Heat improves user experience.

In the following, an example is provided, each step shown in fig. 5 to be described in detail.Assuming that current air conditioner 100 The accumulative h=250 hours refrigerating operaton time (h > H0), meet self-cleaning condition, user opens automatically cleaning mould by remote controler Formula.It after air conditioner 100 enters automatically cleaning mode, runs in cooling mode, controller 110 is by the aperture of electric expansion valve 150 It is transferred to 75pls, the frequency of compressor 140 rises to 55Hz, after running 10min, 130 frosting of evaporator.In cooling mode, it controls The aperture of electric expansion valve 150 is transferred to 200pls by device 110, and the frequency of compressor 140 is transferred to 35Hz, runs defrost after 1min. In cooling mode, the aperture of electric expansion valve 150 is transferred to 120pls by controller 110, and the frequency of compressor 140 is transferred to 45Hz, after running 5min, the surface of evaporator 130 forms many condensed waters.Controller 110 is by air conditioner 100 by refrigeration mode Heating mode is switched to, the aperture of electric expansion valve 150 is adjusted to 105pls, the frequency of compressor 140 is adjusted to 45Hz, beats simultaneously Ultraviolet radiator 170 is opened, waste heat 8min is blown, eliminating bacteria completes automatically cleaning sterilizing process.
