For example, the air conditioner performs a deep cleaning of the heat exchanger 11 on 5/1/2022, performs a light cleaning of the heat exchanger 11 on 11/2022/5/21/2022, and performs a deep cleaning of the heat exchanger 11 on 31/2022/5 (no light cleaning is performed separately), that is, performs two light cleanings between two consecutive deep cleanings.
It should be noted that, in practical applications, a person skilled in the art may set specific values of the first preset time period T1 and the second preset time period T2 through experiments or experience.
It should be noted that, in practical applications, those skilled in the art may set the air output and the adjustment period of the fan 12 during light cleaning to be the same as those of the fan 12 during deep cleaning, or may set the air output and the adjustment period of the fan 12 during light cleaning to be different from those of the fan 12 during deep cleaning, or may set one of the air output and the adjustment period during light cleaning to be the same as those during deep cleaning, and set the other one of the air output and the adjustment period to be different from those during deep cleaning, etc., and such flexible adjustment and change do not depart from the principle and scope of the present invention, and should be included in the protection scope of the present invention.

Through the arrangement, the concentration of the obtained particle pollutants in the air is compared with the preset concentration, whether the external environment where the outdoor unit 1 is located has sand and dust and the severity of the sand and dust condition can be judged, whether the heat exchanger 11 needs to be slightly cleaned in advance is judged according to the sand and dust condition of the external environment, on one hand, when the sand and wind are serious, excessive dust is prevented from being accumulated on the heat exchanger 11 due to untimely cleaning, the heat exchange efficiency is prevented from being influenced, and meanwhile, the difficulty of the next slight cleaning or deep cleaning is prevented from being increased; on the other hand, when there is no wind sand, it is not necessary to clean the heat exchanger 11 lightly in advance, thereby contributing to energy saving.
It should be noted that, in practical applications, those skilled in the art may directly compare the concentration of the particulate contaminant with the preset concentration, or may first calculate a difference between the concentration of the particulate contaminant and the preset concentration and then compare the difference with the preset value, or may first calculate a ratio between the concentration of the particulate contaminant and the preset concentration and then compare the ratio with the preset value, and the like, and such flexible adjustment and change do not depart from the principle and scope of the present invention and are all included in the protection scope of the present invention.
It should be further noted that, in practical applications, in order to reduce the false determination rate of the concentration of the particulate pollutants caused by the wind blowing up the dust, when the concentration of the particulate pollutants is greater than the preset concentration, the duration of the concentration of the particulate pollutants being greater than the preset concentration may be compared with the preset time, so that the accuracy of determining the dust condition of the external environment of the outdoor unit 1 can be improved.
Illustratively, if the duration of the time that the concentration of the particulate pollutants is greater than the preset concentration does not exceed the first preset time, it indicates that the outdoor unit 1 is located in an external environment without sand or with slight sand; if the duration time that the concentration of the particulate pollutants is greater than the preset concentration exceeds the first preset time but does not exceed the second preset time, it indicates that the external environment where the outdoor unit 1 is located has sand and dust, but the sand and dust condition is not serious; if the duration of the concentration of the particulate pollutants is greater than the preset concentration exceeds a second preset time, it indicates that the dust and sand condition in the external environment where the outdoor unit 1 is located is serious.
Preferably, as shown in fig. 3, the step of "selectively performing the light cleaning of the heat exchanger 11 in advance according to the comparison result" specifically includes:
s5210: if the concentration of the particulate pollutants is greater than the preset concentration and the duration that the concentration of the particulate pollutants is greater than the preset concentration reaches the first preset time but does not reach the second preset time, obtaining the operating time T0 of the air conditioner after the heat exchanger 11 is deeply cleaned last time;
s5220: according to the operating time period T0, the heat exchanger 11 is selectively cleaned lightly in advance.
Through the arrangement, if the concentration of the particulate pollutants in the air is greater than the preset concentration, and the duration time that the concentration of the particulate pollutants is greater than the preset concentration reaches the first preset time but does not reach the second preset time, it is described that the external environment where the outdoor unit 1 is located has sand and dust, but the sand and dust condition is not very serious, and then whether to slightly clean the heat exchanger 11 is determined according to the running time of the air conditioner after the heat exchanger 11 is deeply cleaned last time, on one hand, if the time at this time is closer to the next deep cleaning time, the heat exchanger 11 does not need to be slightly cleaned in advance, which is beneficial to saving energy; on the other hand, if the time from the next deep cleaning is still longer, the heat exchanger 11 needs to be lightly cleaned in advance to avoid that the dust accumulated on the heat exchanger 11 is too much to affect the next light cleaning or deep cleaning.
It should be noted that, in practical applications, a person skilled in the art may directly compare the operation time period T0 with the preset value a, and selectively perform mild cleaning on the heat exchanger 11 in advance according to a comparison result; or, the difference between T1 and T0 may be calculated first, and then the difference is compared with the preset value a, and according to the comparison result, the heat exchanger 11 is selectively cleaned slightly in advance; still alternatively, T0 may be directly compared with T1, and the heat exchanger 11 may be selectively cleaned in advance according to the comparison result, and such flexible adjustment and change without departing from the principle and scope of the present invention should be included in the protection scope of the present invention.
Preferably, as shown in fig. 3, the step of "selectively pre-cleaning the heat exchanger 11 lightly according to the operation time period T0" specifically includes:
s5221: calculating a difference Δ T = T1-T0;
s5222: comparing the difference value delta T with a preset value A;
s5223: if DeltaT is more than A, the heat exchanger 11 is slightly cleaned in advance;
s5224: if DeltaT is less than or equal to A, the heat exchanger 11 is not cleaned lightly in advance.
Through the arrangement, if delta T is larger than A, the difference between T1 and T0 is larger, namely the time from the next deep cleaning is longer, the heat exchanger 11 needs to be slightly cleaned in advance, and the influence of the excessive dust accumulated on the heat exchanger 11 on the next light cleaning or deep cleaning is avoided; if delta T is less than or equal to A, the difference between T1 and T0 is not large, that is, the next deep cleaning is performed quickly, and at the moment, the heat exchanger 11 does not need to be cleaned slightly in advance, so that the energy is saved, and the use experience of a user is further improved.
Preferably, the step of "selectively pre-cleaning the heat exchanger 11 according to the comparison result" further comprises:
if the concentration of the particulate contaminants is greater than the preset concentration and the duration that the concentration of the particulate contaminants is greater than the preset concentration reaches a second preset time, the heat exchanger 11 is lightly cleaned in advance.
Through such setting, if the concentration of granule class pollutant is greater than predetermineeing concentration and the duration that the concentration of granule class pollutant is greater than predetermineeing concentration reaches the second and predetermines the time, then explain the sand and dust condition of the environment at off-premises station 1 place more seriously, no matter at this moment apart from the length of the time of the next deep cleaning, all need carry out slight cleaning to heat exchanger 11, prevent to influence heat exchange efficiency of heat exchanger 11 because can not remove dust in time when the sand and dust is more in the air, avoid making dust pile up too much and influence the light cleaning or the deep cleaning of next time on heat exchanger 11 simultaneously.
It should be noted that, in the case of not performing the light cleaning on the heat exchanger 11 in advance, after each time of the deep cleaning, the light cleaning is performed on the heat exchanger 11 at an interval of the second preset time period T2, and if the condition of performing the light cleaning on the heat exchanger 11 in advance is not satisfied after the light cleaning is completed, the light cleaning is still performed on the heat exchanger 11 at an interval of the second preset time period T2.
It should be noted that, in practical applications, since the heat exchanger 11 is cleaned slightly in advance, it is likely that the time of the light cleaning overlaps the time of the deep cleaning, and the operation status of the fan 12 in both the light cleaning and the deep cleaning involves blowing air toward the heat exchanger 11 by the fan 12 and periodically adjusting the air output of the fan 12, so that the light cleaning and the deep cleaning can be performed simultaneously without mutual interference of the control procedures.
Illustratively, if the times of the light cleaning and the deep cleaning are just coincident, the light cleaning and the deep cleaning are started simultaneously, and in the defrosting process of the air conditioner, because the fan 12 blows air towards the heat exchanger 11 and the air outlet quantity of the fan 12 is periodically adjusted, the fan 12 does not need to be started repeatedly, and the air outlet quantity of the fan 12 blows off frost blocks on the heat exchanger 11;
if light cleaning occurs before deep cleaning, when the deep cleaning is performed and the light cleaning is not finished, the fan 12 blows air towards the heat exchanger 11 and the air output of the fan 12 is periodically adjusted, and the operation is performed until the deep cleaning is finished, and because the light cleaning blows off the dust on the heat exchanger 11, the dust on the heat exchanger 11 is easier to combine with frost blocks during the deep cleaning, and the deep cleaning effect is better;
if light cleaning takes place after the deep cleaning, when deep cleaning has not been accomplished yet, need carry out light cleaning, make fan 12 blow towards heat exchanger 11 and adjust the air output of fan 12 periodically, and move until light cleaning finishes, moreover, because after deep cleaning, can have moisture that a small amount of frost cake melted on the heat exchanger 11, light clean operation can be with moisture on the heat exchanger 11 weathers, avoids influencing the heat exchange efficiency of heat exchanger 11.
It should be further noted that the air conditioner of the present invention further includes a controller, the controller is communicatively connected to the particulate contamination detecting member, and the controller is configured to execute the control method described above.
Finally, the control method of the present invention will be described with reference to a specific example.
Exemplarily, the first preset time period T1=29 days, the second preset time period T2=9 days, the first preset time =3 hours, the second preset time =6 hours, and the preset value a =1.
For example, in 2022, 5/month/1, the air conditioner performs deep cleaning of the heat exchanger 11.
Normally, the heat exchanger 11 is lightly cleaned once again at 11 days 5 and 21 days 2022, respectively, and the heat exchanger 11 is deeply cleaned once again at 31 days 5 and 31 days 2022.
In exceptional cases 1, the concentration of the particulate pollutants in the air is detected to be higher than the preset concentration at 5/15 days 2022, but the duration is only 1 hour, so that the heat exchanger 11 does not need to be slightly cleaned in advance, and the heat exchanger 11 needs to be slightly cleaned again by 21 days at 5/2022.
Exceptional cases 2, the concentration of the particulate pollutants in the air is detected to be higher than the preset concentration in 2022, month 5 and day 15, the duration reaches 5 hours, the operation time is 14 days since the last deep cleaning, and the heat exchanger 11 needs to be slightly cleaned in advance because (29-14) > 1.
In exceptional cases 3, the duration of detecting that the concentration of the particulate pollutants in the air is greater than the preset concentration for 5 hours at 5/29 days in 2022, the operation time is 29 days since the last deep cleaning, (29-28) =1, it is not necessary to perform a light cleaning on the heat exchanger 11 in advance, and it is only necessary to perform a deep cleaning on the heat exchanger 11 directly by 31/5/2022.
In exceptional cases 4, when the concentration of the particulate pollutants in the air is detected to be higher than the preset concentration at 5/29/2022 and the duration reaches 7 hours, the heat exchanger 11 needs to be lightly cleaned in advance, and the heat exchanger 11 needs to be deeply cleaned again at 31/5/2022.
So far, the technical solutions of the present invention have been described in connection with the preferred embodiments shown in the drawings, but it is easily understood by those skilled in the art that the scope of the present invention is obviously not limited to these specific embodiments. Equivalent changes or substitutions of related technical features can be made by those skilled in the art without departing from the principle of the invention, and the technical scheme after the changes or substitutions can fall into the protection scope of the invention.
