Description

TECHNICAL FIELD

[0001] The present application relates to the air conditioning technical field, and particularly to an air conditioner self-cleaning method, device, air conditioner and storage medium. BACKGROUND

[0002] At present, air conditioners account for a higher and higher proportion of people's daily life, greatly facilitating people's production and life. However, the evaporator of the indoor unit of the air conditioner will accumulate dust, which will affect the heat exchange efficiency, and thus cause problems such as air conditioner not cooling or slow cooling.

[0003] In order to solve the above problems, the air conditioner can remove the dust on the evaporator by self-cleaning. The principle of self-cleaning is to set the indoor fan to a target speed, so that the evaporator is frosted. In the frosting process, the water volume changes because the water vapor in the air changes into ice frost, which can loosen the attached dust. Then defrosting can be carried out, and in the defrosting process, the condensed ice frost will melt, and the dust will flow with the condensed water, thereby realizing self-cleaning.

[0004] Based on the above self-cleaning principle, the current air conditioner self-cleaning method can fix the duration of self-cleaning, thereby removing the dust on the evaporator. However, the fixed duration of self-cleaning can cause poor self-cleaning effect or waste of electric energy. SUMMARY

[0005] The present application provides an air conditioner self-cleaning method, device, air conditioner and storage medium, which solves the defects of the prior art that the fixed duration of self-cleaning can cause poor self-cleaning effect or waste of electric energy, and achieves better cleaning effect while saving electric energy.

[0016] In a case where the indoor temperature is greater than the target temperature threshold and the indoor humidity is greater than the target humidity threshold, a fourth threshold is determined as the to-be-used quality threshold from the pre-acquired target correspondence relationship between the target temperature interval, the target humidity interval and the quality threshold, wherein the fourth threshold is less than the second threshold, the fourth threshold is greater than the third threshold, and a relationship between the first threshold and the fourth threshold is determined based on the target temperature threshold and the target humidity threshold.

[0055] In order to make the objects, technical solutions and advantages of the present application clearer, the technical solutions in the present application will be described clearly and completely below in conjunction with the drawings in the present application. Obviously, the described embodiments are some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

[0056] In order to facilitate understanding of the self-cleaning method of the air conditioner provided by the embodiments of the present application, the principle of the self-cleaning function will be introduced first: the self-cleaning function is that, during the operation of the air conditioner, the condensate water generated by the frosting / descaling of the evaporator is used to clean the dirt on the evaporator. The most direct way is to stop the fan in the air conditioner, the indoor unit stops heat exchange, the temperature of the refrigerant in the pipeline is extremely low, thus frosting, and after frosting, the fan is started, the heat exchange is restored, the condensate water is generated by defrosting, and the dirt is removed. In the design stage, because the control logic of the self-cleaning is certain, the duration of the self-cleaning, the control mode is certain, and the cleaning effect of the self-cleaning cannot be directly judged.

[0057] For example, the fixed duration of the self-cleaning is duration 1, and in the duration 1, the period of the self-cleaning can be multiple, that is, the frosting-defrosting process can be repeated multiple times (the number of times of the self-cleaning can be accumulated multiple times). In this way, the air conditioner can have been cleaned, but the frosting-defrosting process is still repeated, resulting in waste of electric energy. The air conditioner can also not have been cleaned, but the frosting-defrosting process is no longer performed, resulting in poor cleaning effect.

[0058] In order to solve the problem of poor self-cleaning effect or waste of electric energy caused by the fixed duration of the self-cleaning, the embodiments of the present application provide a self-cleaning method, device, air conditioner, non-transitory computer readable storage medium and computer program product of the air conditioner, which will be described below in conjunction with Figure 1The application provides a self-cleaning method of an air conditioner.

[0059] As shown in Figure 1 The application provides a self-cleaning method of an air conditioner, which comprises the following steps:

[0060] S101, if the current accumulated self-cleaning times meet preset times conditions, the condensate water quality, indoor temperature and indoor humidity are obtained under the condition that the self-cleaning function of the air conditioner is turned on.

[0061] If the current accumulated self-cleaning times meet preset times conditions, the condensate water quality, indoor temperature and indoor humidity can be obtained under the condition that the self-cleaning function of the air conditioner is turned on. In an embodiment, the self-cleaning times meet the preset times conditions when one self-cleaning cycle (i.e. the process of frosting-defrosting) is performed, that is, the self-cleaning times is 1.

[0062] In another embodiment, the self-cleaning times meet the preset times conditions when the number of self-cleaning cycles to be used (i.e. the number of preset times of the process of frosting-defrosting) is performed, that is, the self-cleaning times is an integer multiple of the number of self-cleaning cycles to be used. This is reasonable.

[0063] As an embodiment, the water quality detection device can be used to detect the quality of the condensate water to obtain the condensate water quality. The temperature detection device can be used to detect the indoor temperature, and the humidity detection device can be used to detect the indoor humidity.

[0064] S102, a quality threshold to be used which matches the indoor temperature and the indoor humidity is determined from the target corresponding relationship between the target temperature range, the target humidity range and the quality threshold.

[0065] After the indoor temperature and the indoor humidity are obtained, a quality threshold to be used which matches the indoor temperature and the indoor humidity can be determined from the target corresponding relationship between the target temperature range, the target humidity range and the quality threshold.

[0066] For example, the target corresponding relationship can be shown in Table 1.

[0067] Table 1

[0068] Target temperature interval Target humidity interval Quality threshold Target temperature interval 1 Target humidity interval 1 Quality threshold 1 Target temperature interval 1 Target humidity interval 2 Quality threshold 2 Target temperature interval 2 Target humidity interval 1 Quality threshold 3 Target temperature interval 2 Target humidity interval 2 Quality threshold 4

[0069] That is, the target temperature range in which the indoor temperature is located needs to be determined, and the target humidity range in which the indoor humidity is located needs to be determined, so as to obtain the corresponding quality threshold. In combination with Table 1, the quality threshold 1 is determined to be the quality threshold to be used when the indoor temperature is in the target temperature range 1 and the indoor humidity is in the target humidity range 1.

[0070] After obtaining the condensate water quality and the to-be-used quality threshold, the relationship between the condensate water quality and the to-be-used quality threshold can be compared, and different steps can be performed based on the relationship between the condensate water quality and the to-be-used quality threshold.

[0071] S103, in the case where the condensate water quality is not greater than the to-be-used quality threshold, keeping the self-cleaning function open.

[0072] In the case where the condensate water quality is not greater than the to-be-used quality threshold, it indicates that the condensate water quality is unqualified, and thus the air conditioner still needs to be self-cleaned. Therefore, the self-cleaning function can be kept open continuously, so as to perform the next self-cleaning cycle, that is, to perform the next frosting-defrosting process.

[0073] In the case where the self-cleaning number of times again meets the preset number of times condition, the step of obtaining the condensate water quality can be performed again until the condensate water quality is greater than the to-be-used quality threshold. In this way, the cleaning effect can be better.

[0074] S104, in the case where the condensate water quality is greater than the to-be-used quality threshold, closing the self-cleaning function.

[0075] In the case where the condensate water quality is greater than the to-be-used quality threshold, it indicates that the air conditioner has been cleaned, and in order to save electric energy, the self-cleaning function can be closed. It can be seen that in the embodiment, whether to continue self-cleaning can be determined according to the quality of the condensate water, and thus better cleaning effect can be achieved while saving electric energy.

[0076] The embodiment of the present application can detect the quality of the condensate water generated after defrosting on the basis of the self-cleaning function, and calibrate the standard quality (to-be-used quality threshold) of the qualified condensate water during the development stage. When the quality of the condensate water (condensate water quality) does not reach the standard quality (to-be-used quality threshold), the self-cleaning function continues to run until the standard quality (to-be-used quality threshold) is reached, and then the self-cleaning function is closed. The embodiment of the present application detects the self-cleaning sterilization effect by collecting the quality of the condensate water, and feeds back to the control system to control the self-cleaning function.

[0077] The variable frequency air conditioner on the market can only improve the self-cleaning efficiency by optimizing the control of the compressor frequency, fan speed and the like, but cannot directly detect the cleaning sterilization effect of self-cleaning. The embodiment of the present application can directly evaluate the self-cleaning effect by collecting the quality of the condensate water, and stop the self-cleaning function only when the condensate water reaches a certain quality value. Meanwhile, the present application controls the running depth of the self-cleaning by the feedback of the condensate water quality, and can control the self-cleaning effect.

[0078] As an implementation of an embodiment of the present application, the target temperature interval is an interval divided based on a pre-set target temperature threshold, and the target humidity interval is an interval divided based on a pre-set target humidity threshold.

[0079] The step of determining the to-be-used quality threshold that matches both the indoor temperature and the indoor humidity from the pre-set target temperature interval, target humidity interval, and target corresponding relationship of the quality threshold includes:

[0080] In a case where the indoor temperature is not greater than the target temperature threshold and the indoor humidity is not greater than the target humidity threshold, a first threshold is determined as the to-be-used quality threshold from the pre-set target temperature interval, target humidity interval, and target corresponding relationship of the quality threshold.

[0081] In a case where the indoor temperature is not greater than the target temperature threshold and the indoor humidity is greater than the target humidity threshold, a second threshold is determined as the to-be-used quality threshold from the pre-set target temperature interval, target humidity interval, and target corresponding relationship of the quality threshold, where the second threshold is greater than the first threshold.

[0082] In a case where the indoor temperature is greater than the target temperature threshold and the indoor humidity is not greater than the target humidity threshold, a third threshold is determined as the to-be-used quality threshold from the pre-set target temperature interval, target humidity interval, and target corresponding relationship of the quality threshold, where the third threshold is less than the first threshold.

[0083] In a case where the indoor temperature is greater than the target temperature threshold and the indoor humidity is greater than the target humidity threshold, a fourth threshold is determined as the to-be-used quality threshold from the pre-set target temperature interval, target humidity interval, and target corresponding relationship of the quality threshold, where the fourth threshold is less than the second threshold, the fourth threshold is greater than the third threshold, and the relationship between the first threshold and the fourth threshold is determined based on the target temperature threshold and the target humidity threshold.

[0084] Since water vapor in the air will condense into water droplets when the indoor temperature decreases. This is because the condensation temperature of water vapor is related to the humidity of water vapor. In a case where the indoor humidity is high, the condensation temperature of water vapor is lower, and thus condensate water is likely to occur even if the indoor temperature is low. Conversely, when the temperature of the air increases, the water vapor in the air will evaporate, and thus the formation of condensate water is unlikely to occur.

[0085] Therefore, in a case where the indoor temperature is not greater than the target temperature threshold value and the indoor humidity is not greater than the target humidity threshold value, it is indicated that the indoor temperature and the indoor humidity are both low, and the first threshold value is determined as the to-be-used quality threshold value from the target correspondence relationship between the target temperature interval, the target humidity interval and the quality threshold value.

[0086] In a case where the indoor temperature is not greater than the target temperature threshold value and the indoor humidity is greater than the target humidity threshold value, it is indicated that the temperature is low and the humidity is high, and the second threshold value can be determined as the to-be-used quality threshold value from the target correspondence relationship between the target temperature interval, the target humidity interval and the quality threshold value. The second threshold value is greater than the first threshold value.

[0087] In a case where the indoor temperature is greater than the target temperature threshold value and the indoor humidity is not greater than the target humidity threshold value, it is indicated that the indoor temperature is high and the humidity is low, and the third threshold value can be determined as the to-be-used quality threshold value from the target correspondence relationship between the target temperature interval, the target humidity interval and the quality threshold value. Since the higher the temperature is, the easier the water vapor evaporates, the first threshold value is greater than the third threshold value, that is, the third threshold value is less than the first threshold value.

[0088] In a case where the condensate water is less, the condensate water corresponds to a higher turbidity, and therefore, in order to more accurately know the effect corresponding to the self-cleaning, the third threshold value can be set to be less than the first threshold value.

[0089] In a case where the indoor temperature is greater than the target temperature threshold value and the indoor humidity is greater than the target humidity threshold value, it is indicated that the indoor temperature is high, but the humidity is high, and therefore, the fourth threshold value can be determined as the to-be-used quality threshold value from the target correspondence relationship between the target temperature interval, the target humidity interval and the quality threshold value, where the fourth threshold value is greater than the third threshold value, the fourth threshold value is less than the second threshold value, and the relationship between the first threshold value and the fourth threshold value can be determined based on the target temperature threshold value and the target humidity threshold value.

[0090] Different regions correspond to different temperature and humidity, and in order to be able to combine the climate conditions of different regions to realize the self-cleaning method of the air conditioner provided in the embodiments of the present application, the relationship between the first threshold value and the fourth threshold value can be determined based on the target temperature threshold value and the target humidity threshold value.

[0091] In an implementation, the target humidity threshold value can be divided into a plurality of humidity level intervals, in a case where the humidity level interval where the target temperature threshold value is located is high, even if the indoor humidity is not greater than the humidity threshold value, the indoor humidity can still be high. In this case, the first threshold value is greater than the fourth threshold value.

[0092] When the humidity level interval where the target temperature threshold is located is low, the indoor humidity is low. In this case, the higher the temperature is, the less conducive to the formation of condensed water, and therefore the fourth threshold is greater than the first threshold. The fourth threshold can be set according to actual use requirements.

[0093] It can be seen that in the embodiment, the to-be-used quality threshold can be determined according to different intervals of the indoor temperature and the indoor humidity, so that the corresponding condensed water quality standard can be determined according to different indoor temperatures and indoor humidities, and subsequent more accurate self-cleaning control can be conveniently implemented, so that better cleaning effect can be achieved while saving electric energy.

[0094] To facilitate understanding of the self-cleaning method of the air conditioner provided by the embodiment of the present application, the following describes the self-cleaning method of the air conditioner provided by the embodiment of the present application with reference to the accompanying drawings. Figure 2 and Figure 3 The self-cleaning method of the air conditioner provided by the embodiment of the present application is introduced.

[0095] As shown in Figure 2 , the self-cleaning method of the air conditioner provided by the embodiment of the present application can include the following steps:

[0096] If the current accumulated self-cleaning number meets the preset number condition when the air conditioner self-cleaning function is turned on, step S201 is performed.

[0097] S201, obtain the condensed water quality.

[0098] S202, obtain the indoor temperature and the indoor humidity, and determine the to-be-used quality threshold that matches the indoor temperature and the indoor humidity from a target corresponding relationship between the target temperature interval, the target humidity interval and the quality threshold.

[0099] S203, determine whether the condensed water quality is greater than the to-be-used quality threshold.

[0100] Step S203 is to determine whether the condensed water quality meets the corresponding standard quality. In the case where the condensed water quality is not greater than the to-be-used quality threshold, step S204 can be performed, and in the case where the condensed water quality is greater than the to-be-used quality threshold, step S205 can be performed.

[0101] S204, keep the self-cleaning function turned on, and perform step S201 when the self-cleaning number again meets the preset number condition.

[0102] S205, turn off the self-cleaning function.

[0103] As shown in Figure 3 , the above step S202 can specifically include:

[0104] S301, set a target temperature threshold and a target humidity threshold;

[0105] Wherein, the target temperature threshold can be represented by Ts, and the target humidity threshold can be represented by Hs.

[0106] S302, obtaining indoor temperature and indoor humidity;

[0107] Wherein, the indoor temperature can be represented by T0, and the indoor humidity can be represented by H0.

[0108] S303, in the case that the indoor temperature is not greater than the target temperature threshold, and the indoor humidity is not greater than the target humidity threshold, determining the first threshold as the to-be-used quality threshold from the target correspondence relationship between the target temperature range, the target humidity range and the quality threshold.

[0109] The above step S303 is that in the case of Ts≥T0 and Hs≥H0, Ms=M1, wherein, Ms is the to-be-used quality threshold, and M1 is the first threshold.

[0110] S304, in the case that the indoor temperature is not greater than the target temperature threshold, and the indoor humidity is greater than the target humidity threshold, determining the second threshold as the to-be-used quality threshold from the target correspondence relationship between the target temperature range, the target humidity range and the quality threshold.

[0111] Wherein, the second threshold is greater than the first threshold

[0112] The above step S304 is that in the case of Ts≥T0 and Hs<H0, Ms=M2, wherein, M2 is the second threshold.

[0113] S305, in the case that the indoor temperature is greater than the target temperature threshold, and the indoor humidity is not greater than the target humidity threshold, determining the third threshold as the to-be-used quality threshold from the target correspondence relationship between the target temperature range, the target humidity range and the quality threshold.

[0114] Wherein, the third threshold is less than the first threshold.

[0115] The above step S305 is that in the case of Ts<T0 and Hs≥H0, Ms=M3, wherein, M3 is the third threshold.

[0116] S306, in the case that the indoor temperature is greater than the target temperature threshold, and the indoor humidity is greater than the target humidity threshold, determining the fourth threshold as the to-be-used quality threshold from the target correspondence relationship between the target temperature range, the target humidity range and the quality threshold.

[0117] Wherein, the fourth threshold is less than the second threshold, the fourth threshold is greater than the third threshold, and the relationship between the first threshold and the fourth threshold is determined based on the temperature threshold and the humidity threshold.

[0118] The step S306 is that when Ts < T0 and Hs < H0, Ms = M4, wherein M4 is a fourth threshold value. M2 > M1 > M3, and M2 > M4 > M3.

[0119] As an embodiment of the present application, the target temperature range and the target humidity range can be determined in the following manner:

[0120] Obtaining environment adjustment information, wherein the environment adjustment information comprises at least one of position information, ventilation information and weather information.

[0121] The position information can be the position information of the air conditioner, and can also be the position information of a room corresponding to the air conditioner. The ventilation information can be ventilation situation information of a room corresponding to the air conditioner, for example, information such as whether a door is open, whether a window is open, whether an electric fan is on, etc. The weather information can be real-time weather information, and can also be predicted weather information, and can also be outdoor temperature and outdoor humidity. The specific setting can be made according to actual use requirements.

[0122] Adjusting a pre-set temperature range and / or a pre-set humidity range based on the environment adjustment information, to obtain an adjusted temperature range and / or an adjusted humidity range;

[0123] In the case of only obtaining the adjusted temperature range, the adjusted temperature range is taken as the target temperature range, and the pre-set humidity range is taken as the target humidity range.

[0124] In the case of only obtaining the adjusted humidity range, the adjusted humidity range is taken as the target humidity range, and the pre-set temperature range is taken as the target temperature range.

[0125] In the case of obtaining the adjusted temperature range and the adjusted humidity range, the adjusted temperature range is taken as the target temperature range, and the adjusted humidity range is taken as the target humidity range.

[0126] As an embodiment of the present application, the weather information can comprise a corresponding relationship between predicted weather information and a predicted time period. The predicted weather information can be predicted weather information corresponding to different time periods.

[0127] For each predicted time period, when the current time is in the predicted time period, based on the predicted weather information corresponding to the predicted time period, a target temperature range and a target humidity range corresponding to the predicted time period are determined from a pre-set corresponding relationship between weather information, temperature ranges and humidity ranges.

[0128] That is, the target temperature interval and the target humidity interval corresponding to different time periods can be determined according to the predicted weather information, so that the accuracy of determining whether the self-cleaning function needs to be closed can be improved.

[0129] As an embodiment of the present application, the environment adjustment information includes ventilation information and outdoor humidity, and the ventilation information is information indicating whether the ventilation port is in a ventilation state.

[0130] The step of adjusting the preset temperature interval and / or the preset humidity interval based on the environment adjustment information, and obtaining the adjusted temperature interval and / or the adjusted humidity interval, can include:

[0131] Based on the position information, the to-be-used ventilation port is obtained from a preset correspondence between positions and ventilation ports. The to-be-used ventilation port includes at least one, and the to-be-used ventilation port has a preset to-be-used weight.

[0132] In an embodiment, the to-be-used weight can include a ventilation weight corresponding to different opening degrees of each to-be-used ventilation port. Accordingly, the to-be-used weight corresponding to the to-be-used ventilation port in the ventilation state can be the ventilation weight corresponding to the opening degree of the to-be-used ventilation port in the ventilation state. In this way, a more accurate to-be-used value can be obtained.

[0133] In the case where the ventilation information indicates that there is a to-be-used ventilation port in the ventilation state, it is indicated that the ventilation port in the ventilation state has a greater impact on the indoor temperature and the indoor humidity. Therefore, the to-be-used value can be determined from a preset correspondence between weights and adjustment values based on the to-be-used weight corresponding to the to-be-used ventilation port in the ventilation state.

[0134] After obtaining the to-be-used value, the preset temperature interval and the preset humidity interval can be adjusted based on the to-be-used value, and the adjusted temperature interval and the adjusted humidity interval are obtained. The to-be-used value can be a positive number or a negative number.

[0135] The preset temperature interval is an interval divided based on a preset temperature, and the preset humidity interval is an interval divided based on a preset humidity. The to-be-used value includes a to-be-used temperature value and a to-be-used humidity value. The to-be-used value includes a to-be-used temperature value and a to-be-used humidity value.

[0136] The step of adjusting the preset temperature interval and the preset humidity interval based on the to-be-used value, and obtaining the adjusted temperature interval and the adjusted humidity interval, can include:

[0137] The sum of the to-be-used temperature value and the preset temperature is taken as a target temperature threshold, and an interval divided by the target temperature threshold is an adjusted temperature interval.

[0138] The sum of the to-be-used humidity value and the preset humidity is taken as a target humidity threshold, and an interval divided by the target humidity threshold is an adjusted temperature interval.

[0139] Because different ventilation conditions affect indoor temperature and indoor humidity, thereby affecting the formation of condensate water, and different ventilation openings have different degrees of influence on indoor temperature and indoor humidity, the to-be-used ventilation opening that has a greater influence on indoor temperature and indoor humidity can be determined first, and the corresponding to-be-used value is determined in the case that the to-be-used ventilation opening is in a ventilation state, and then the pre-set temperature interval and the pre-set humidity interval can be adjusted, and a more accurate target temperature interval and target humidity interval are obtained, so that the accuracy of subsequent judgment of whether the self-cleaning function needs to be closed can be further improved.

[0140] In the case that the ventilation information indicates that there is no to-be-used ventilation opening in a ventilation state, it is indicated that the ventilation opening that has a greater influence on indoor temperature and indoor humidity is not in a ventilation state, and the pre-set temperature interval and the pre-set humidity interval can not be adjusted, and therefore the pre-set temperature interval can be taken as a target temperature interval, and the pre-set humidity interval can be taken as a target humidity interval.

[0141] As an embodiment of the present application, the above-mentioned environment adjustment information includes ventilation information and outdoor humidity, wherein the ventilation information is information indicating whether a ventilation opening is in a ventilation state, and the ventilation opening has a pre-set ventilation opening weight:

[0142] The step of adjusting the pre-set temperature interval and / or the pre-set humidity interval based on the environment adjustment information, and obtaining an adjusted temperature interval and / or an adjusted humidity interval, can include:

[0143] In the case that the outdoor humidity is greater than a preset outdoor humidity threshold, and the ventilation information indicates that there is a humidity ventilation opening in a ventilation state, a humidity adjustment value is determined based on the outdoor humidity and a corresponding relationship between a pre-set humidity and a humidity value, wherein the humidity ventilation opening is a ventilation opening with a ventilation opening weight greater than a pre-set weight threshold. The humidity adjustment value can be a positive number.

[0144] The pre-set humidity interval is adjusted based on the humidity adjustment value, and an adjusted humidity interval is obtained. In an embodiment, the sum of the humidity adjustment value and a preset humidity can be taken as a target humidity threshold. In this way, a target humidity interval divided by the target humidity threshold can be obtained.

[0145] In a case where the outdoor humidity is not greater than the preset humidity threshold value, and / or the ventilation information indicates that there is no humidity ventilation port in the ventilation state, it is indicated that the outdoor humidity has a low influence on the indoor humidity, and thus the preset humidity interval can be taken as the target humidity interval without adjusting the preset humidity interval.

[0146] It can be seen that in the embodiment, whether to adjust the preset humidity interval can be determined according to different situations, so that a more accurate target humidity interval is obtained.

[0147] As an implementation manner of the embodiment, the environment adjustment information can include position information and weather information, and the weather information can be real-time weather information.

[0148] The step of adjusting the preset temperature interval and / or the preset humidity interval based on the environment adjustment information can include:

[0149] Based on the position information, a to-be-used influence position is obtained from a preset position and weather influence position correspondence relationship, and the to-be-used influence position has a preset influence weather.

[0150] The influence weather can be weather with a high direct sunlight temperature, so that the indoor temperature is affected even if the window is not opened, and thus the to-be-used influence position that will affect the indoor temperature can be obtained first.

[0151] In a case where the weather information is consistent with the influence weather, it is indicated that the weather information has a large influence on the indoor temperature. Based on the weather information, a temperature adjustment value is determined from a preset weather and temperature value correspondence relationship.

[0152] The preset temperature interval is adjusted based on the temperature adjustment value to obtain an adjusted temperature interval. In an implementation manner, a sum of the temperature adjustment value and a preset temperature can be taken as a target temperature threshold value to obtain a target temperature interval divided by the target temperature threshold value.

[0153] In a case where the weather information is inconsistent with the influence weather, it is indicated that the weather information has a small influence on the indoor temperature, and thus the preset temperature interval can be taken as the target temperature interval without adjusting the preset temperature interval. In this way, a more accurate target temperature interval can be obtained.

[0154] As an implementation manner of the embodiment, in a case where the current accumulated self-cleaning number is less than 1, the preset number condition is that the current accumulated self-cleaning number is 1.

[0155] If the current accumulated self-cleaning count is greater than 1, the preset count condition is that the quotient of the current accumulated self-cleaning count and the number of uses to be performed is an integer. The number of uses to be performed can be preset, for example, 1, 3, 5, etc. No specific limitation is made here.

[0156] The number of uses to be determined can also be a number determined from a pre-set correspondence between condensate quality and the number of uses. Specifically, if the current accumulated self-cleaning count is 1, it means that the current accumulated self-cleaning count meets the preset count condition, and thus the self-cleaning function remains active. In this way, the number of uses corresponding to the condensate quality can be determined from the pre-set correspondence between condensate quality and the number of uses. This allows for more precise self-cleaning.
