Description

Technical Field

[0001] The present invention relates to the technical field of air conditioners, and in particular to a self-cleaning method and device for an air conditioner, an air conditioner and a storage medium. Background Art

[0002] At present, air conditioning accounts for an increasing proportion of people's daily life, which greatly facilitates people's production and life. However, dust will accumulate on the evaporator of the indoor unit of the air conditioner, which will affect the heat exchange efficiency, and then cause problems such as the air conditioner not cooling or cooling slowly.

[0003] To solve the above problems, the air conditioner can remove the dust on the evaporator through self-cleaning. The principle of self-cleaning is to set the indoor fan to the target speed to frost the evaporator. During the frosting process, the water vapor in the air turns into frost, and the water volume changes, which can loosen the attached dust. Then defrosting can be performed. During the defrosting process, the condensed frost will melt, and the dust will flow with the condensed water, thus achieving self-cleaning.

[0004] Based on the above self-cleaning principle, the current air conditioner self-cleaning method can fix the duration of self-cleaning to remove the dust on the evaporator. However, the method of fixing the duration of self-cleaning will result in poor self-cleaning effect or waste of electricity. Summary of the invention

[0055] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0056] To facilitate understanding of a self-cleaning method for an air conditioner provided in an embodiment of the present invention, the principle of the self-cleaning function is first introduced: the self-cleaning function is that during the operation of the air conditioner, the condensed water generated by the frost / defrost 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. After the indoor unit stops heat exchange, the temperature of the refrigerant in the pipeline is extremely low, resulting in frost. After frosting, the fan is started to resume heat exchange, and defrosting is performed to generate condensed water and remove dirt. During the design stage, since the control logic of self-cleaning is certain, the duration and control method of self-cleaning are certain, and the cleaning effect of self-cleaning cannot be directly judged.

[0057] For example, the duration of the self-cleaning is fixed to duration 1. During duration 1, there can be multiple self-cleaning cycles, that is, the frosting-defrosting process can be repeated multiple times (the number of self-cleaning times can be accumulated multiple times). In this way, the air conditioner has been cleaned, but the frosting-defrosting process is still repeated, resulting in a waste of power. It is also possible that the air conditioner has not 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 in a fixed self-cleaning duration, the embodiments of the present invention provide a self-cleaning method, device, air conditioner, non-transitory computer-readable storage medium and computer program product for an air conditioner. Figure 1A self-cleaning method for an air conditioner provided in an embodiment of the present invention is introduced.

[0059] like Figure 1 As shown, an embodiment of the present invention provides a self-cleaning method for an air conditioner, the method comprising:

[0060] S101, when the air conditioner self-cleaning function is turned on, if the current accumulated number of self-cleaning times meets the preset number condition, the condensed water quality, indoor temperature and indoor humidity are obtained.

[0061] When the air conditioner self-cleaning function is turned on, if the current accumulated self-cleaning times meet the preset times condition, the condensed water quality, indoor temperature and indoor humidity can be obtained. In one embodiment, each time a self-cleaning cycle is executed (i.e., a frosting-defrosting process is executed once), that is, when the self-cleaning times is 1, it can be determined that the self-cleaning times meet the preset times condition.

[0062] In another embodiment, when the self-cleaning times are performed for each number of times to be used (i.e., the frosting-defrosting process is performed for a preset number of times), that is, when the self-cleaning times are an integer multiple of the number of times to be used, it can be determined that the self-cleaning times meet the preset times condition. This is all reasonable.

[0063] As an implementation method, the quality of the condensed water can be detected by a water quality detection device to obtain the quality of the condensed water. The indoor temperature can be detected by a temperature detection device, and the indoor humidity can be detected by a humidity detection device.

[0064] S102, determining a quality threshold to be used that matches both the indoor temperature and the indoor humidity from a preset target correspondence relationship between a target temperature interval, a target humidity interval and a quality threshold.

[0065] After the indoor temperature and the indoor humidity are acquired, a quality threshold to be used that matches both the indoor temperature and the indoor humidity can be determined from the target correspondence between the preset target temperature interval, the target humidity interval and the quality threshold.

[0066] For example, the target correspondence relationship may be as shown in Table 1.

[0067] Table 1

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

[0069] That is to say, it is necessary to determine the target temperature interval of the indoor temperature and the target humidity interval of the indoor humidity, so as to obtain the corresponding quality threshold. In combination with the above Table 1, when the indoor temperature is in the target temperature interval 1 and the indoor humidity is in the target humidity interval 1, the quality threshold 1 can be determined as the quality threshold to be used.

[0070] After the condensed water quality and the quality threshold to be used are obtained, the relationship between the condensed water quality and the quality threshold to be used may be compared, and different steps may be performed based on the relationship between the condensed water quality and the quality threshold to be used.

[0071] S103: When the mass of the condensed water is not greater than the mass threshold to be used, keep the self-cleaning function turned on.

[0072] If the condensed water quality is not greater than the quality threshold to be used, it means that the condensed water quality is unqualified, which means that the air conditioner still needs to be self-cleaned. Therefore, the self-cleaning function can be kept turned on to perform the next self-cleaning cycle, that is, to perform the next frosting-defrosting process.

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

[0074] S104: When the condensed water quality value is greater than the quality threshold to be used, turning off the self-cleaning function.

[0075] When the condensed water quality is greater than the quality threshold to be used, it means that the air conditioner has been cleaned. In order to save power, the self-cleaning function can be turned off. It can be seen that in this embodiment, it is possible to determine whether to continue self-cleaning according to the quality of the condensed water, thereby achieving a better cleaning effect while saving power.

[0076] The embodiment of the present invention can detect the quality of condensed water generated after defrosting on the basis of the self-cleaning function, and calibrate the qualified standard quality of condensed water (quality threshold to be used) during the development stage. When the condensed water quality (condensed water quality) does not reach the standard quality (quality threshold to be used), the self-cleaning function continues to operate until it reaches the standard quality (quality threshold to be used), and then the self-cleaning function is turned off. The embodiment of the present invention completes the detection of the self-cleaning and sterilization effect by collecting the quality of condensed water, and feeds back to the control system to achieve the control of the self-cleaning function.

[0077] The variable frequency air conditioners currently on the market can only improve the self-cleaning efficiency by optimizing the compressor frequency, fan speed and other methods, but cannot directly detect the cleaning and sterilization effect of self-cleaning. However, the embodiments of the present invention can directly evaluate the self-cleaning effect by collecting the quality of condensed water, and only stop the self-cleaning function when the condensed water reaches a certain quality value; at the same time, the present invention can control the self-cleaning depth through the feedback of the condensed water quality, so as to control the self-cleaning effect.

[0078] As an implementation manner of the embodiment of the present invention, the target temperature interval is an interval divided based on a preset target temperature threshold, and the target humidity interval is an interval divided based on a preset target humidity threshold.

[0079] The step of determining the quality threshold to be used that matches both the indoor temperature and the indoor humidity from the preset target correspondence between the target temperature interval, the target humidity interval and the quality threshold comprises:

[0080] When the indoor temperature is not greater than the target temperature threshold and the indoor humidity is not greater than the target humidity threshold, determining a first threshold as the quality threshold to be used from a pre-acquired target correspondence relationship between a target temperature interval, a target humidity interval and a quality threshold;

[0081] When 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 quality threshold to be used from a pre-acquired target correspondence relationship between a target temperature interval, a target humidity interval and a quality threshold, wherein the second threshold is greater than the first threshold;

[0082] When the indoor temperature is greater than the target temperature threshold and the indoor humidity is not greater than the target humidity threshold, determining a third threshold as the quality threshold to be used from a pre-acquired target correspondence relationship among a target temperature interval, a target humidity interval and a quality threshold, wherein the third threshold is less than the first threshold;

[0083] When 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 quality threshold to be used from the pre-acquired target correspondence 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 the relationship between the first threshold and the fourth threshold is determined based on the target temperature threshold and the target humidity threshold.

[0084] When the indoor temperature drops, the water vapor in the air will condense into water droplets. This is because the condensation temperature of water vapor is related to the humidity of the water vapor. When the indoor humidity is high, the condensation temperature of water vapor is lower. Therefore, when the indoor humidity is high, condensation water is easy to appear even if the indoor temperature is low. On the contrary, when the air temperature rises, the water vapor in the air will evaporate, so the formation of condensation water is less likely to occur.

[0085] Therefore, when the indoor temperature is not greater than the target temperature threshold and the indoor humidity is not greater than the target humidity threshold, it means that the indoor temperature and indoor humidity are both low. From the pre-acquired target correspondence between the target temperature range, target humidity range and the quality threshold, the first threshold is determined as the quality threshold to be used.

[0086] When the indoor temperature is not greater than the target temperature threshold and the indoor humidity is greater than the target humidity threshold, it means that the temperature is low and the humidity is high, and the second threshold can be determined as the quality threshold to be used from the pre-acquired target temperature interval, target humidity interval and target correspondence relationship of the quality threshold. The second threshold is greater than the first threshold.

[0087] When the indoor temperature is greater than the target temperature threshold and the indoor humidity is not greater than the target humidity threshold, it means that the indoor temperature is high and the humidity is low, and the third threshold can be determined as the quality threshold to be used from the pre-acquired target temperature interval, target humidity interval and quality threshold target correspondence relationship. Since the higher the temperature, the easier it is for water vapor to evaporate, therefore, the first threshold is greater than the third threshold, that is, the third threshold is less than the first threshold.

[0088] The less condensed water there is, the higher the corresponding turbidity of the condensed water is. Therefore, in order to more accurately know the corresponding effect of self-cleaning, the third threshold value can be set to be smaller than the first threshold value.

[0089] When the indoor temperature is greater than the target temperature threshold and the indoor humidity is greater than the target humidity threshold, it means that the indoor temperature is high, but the humidity is high. Therefore, the fourth threshold can be determined as the quality threshold to be used from the target correspondence between the pre-acquired target temperature interval, the target humidity interval and the quality threshold, wherein the fourth threshold is greater than the third threshold, and the fourth threshold is less than the second threshold, and the relationship between the first threshold and the fourth threshold can be determined based on the target temperature threshold and the target humidity threshold.

[0090] Different regions have different corresponding temperatures and humidities. In order to implement the self-cleaning method of the air conditioner provided in the embodiment of the present invention in combination with the climatic conditions of different regions, the relationship between the first threshold and the fourth threshold can be determined based on the target temperature threshold and the target humidity threshold.

[0091] In one embodiment, the target humidity threshold can be divided into a plurality of humidity level intervals, and when the humidity level interval in which the target temperature threshold is located is high, even if the indoor humidity is not greater than the humidity threshold, the indoor humidity may still be high. In this case, the first threshold is greater than the fourth threshold.

[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, the less favorable it is for the formation of condensed water. Therefore, the fourth threshold is greater than the first threshold. It can be set according to actual use requirements.

[0093] It can be seen that in this embodiment, the quality threshold to be used can be determined according to the different intervals of indoor temperature and indoor humidity, so that the corresponding condensate water quality standard can be determined according to different indoor temperatures and indoor humidity, which can facilitate the subsequent implementation of more precise self-cleaning control, thereby achieving better cleaning effects while saving electricity.

[0094] In order to facilitate understanding of a self-cleaning method for an air conditioner provided by an embodiment of the present invention, Figure 2 and Figure 3 A self-cleaning method for an air conditioner provided in an embodiment of the present invention is introduced.

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

[0096] When the air conditioner self-cleaning function is turned on, if the current accumulated number of self-cleaning times meets the preset number condition, step S201 is executed.

[0097] S201, obtaining the mass of condensed water.

[0098] S202, obtaining indoor temperature and indoor humidity, and determining a quality threshold to be used that matches both the indoor temperature and the indoor humidity from a preset target correspondence relationship between a target temperature range, a target humidity range and a quality threshold.

[0099] S203, determining whether the quality of the condensed water is greater than a quality threshold to be used.

[0100] Wherein, step S203 is to determine whether the condensed water quality reaches the corresponding standard quality. If the condensed water quality is not greater than the quality threshold to be used, step S204 can be executed, and if the condensed water quality is greater than the quality threshold to be used, step S205 can be executed.

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

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

[0103] like Figure 3 As shown, the above step S202 may specifically include:

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

[0105] Among them, 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] Among them, the indoor temperature can be represented by T0 and the indoor humidity can be represented by H0.

[0108] S303, when the indoor temperature is not greater than the target temperature threshold and the indoor humidity is not greater than the target humidity threshold, determine the first threshold as the quality threshold to be used from the pre-acquired target correspondence between the target temperature interval, the target humidity interval 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 quality threshold to be used and M1 is the first threshold.

[0110] S304: When the indoor temperature is not greater than the target temperature threshold and the indoor humidity is greater than the target humidity threshold, determine the second threshold as the quality threshold to be used from the pre-acquired target correspondence between the target temperature interval, the target humidity interval and the quality threshold.

[0111] The second threshold is greater than the first threshold

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

[0113] S305, when the indoor temperature is greater than the target temperature threshold and the indoor humidity is not greater than the target humidity threshold, determine the third threshold as the quality threshold to be used from the pre-acquired target correspondence between the target temperature interval, the target humidity interval and the quality threshold.

[0114] The third threshold is smaller than the first threshold.

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

[0116] S306: When the indoor temperature is greater than the target temperature threshold and the indoor humidity is greater than the target humidity threshold, determine the fourth threshold as the quality threshold to be used from the pre-acquired target correspondence between the target temperature interval, the target humidity interval and the quality threshold.

[0117] The fourth threshold is smaller than the second threshold, the fourth threshold is larger 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 above step S306 is that in the case of Ts<T0 and Hs<H0, Ms=M4, where M4 is the fourth threshold. M2>M1>M3, M2>M4>M3.

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

[0120] Environmental conditioning information is obtained, wherein the environmental conditioning information includes at least one of location information, ventilation information, and weather information.

[0121] The location information may be the location information of the air conditioner, or the location information of the room corresponding to the air conditioner. The ventilation information may be the ventilation information of the room corresponding to the air conditioner, for example, whether the door is open, whether the window is open, whether the fan is turned on, etc. The weather information may be real-time weather information, or forecast weather information, or outdoor temperature, or outdoor humidity. The specific settings may be based on actual usage requirements.

[0122] Adjusting the preset temperature interval and / or the preset humidity interval based on the environmental adjustment information, and correspondingly obtaining an adjusted temperature interval and / or an adjusted humidity interval;

[0123] In the case where only the adjusted temperature interval is obtained, the adjusted temperature interval is used as the target temperature interval, and the preset humidity interval is used as the target humidity interval;

[0124] In the case where only the adjusted humidity interval is obtained, the adjusted humidity interval is used as the target humidity interval, and the preset temperature interval is used as the target temperature interval;

[0125] When the adjusted temperature section and the adjusted humidity section are obtained, the adjusted temperature section is set as the target temperature section, and the adjusted humidity section is set as the target humidity section.

[0126] As an implementation of an embodiment of the present invention, the weather information may include a correspondence between predicted weather information and predicted time periods. The predicted weather information may 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, the target temperature range and target humidity range corresponding to the predicted time period are determined from the correspondence between the pre-set weather information, temperature range and humidity range.

[0128] In other words, the target temperature range and target humidity range corresponding to different time periods can be determined based on the predicted weather information, thereby improving the accuracy of judging whether the self-cleaning function needs to be turned off.

[0129] As an implementation manner of an embodiment of the present invention, the above-mentioned environmental adjustment information includes ventilation information and outdoor humidity, wherein the above-mentioned ventilation information is information indicating whether the ventilation opening is in a ventilation state.

[0130] The above-mentioned step of adjusting the preset temperature interval and / or the preset humidity interval based on the environmental adjustment information to obtain the adjusted temperature interval and / or the adjusted humidity interval may include:

[0131] Based on the position information, the vents to be used are obtained from the correspondence between the preset positions and the vents, wherein the vents to be used include at least one, and the vents to be used have a preset weight to be used.

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

[0133] When the ventilation information indicates that there are vents that are in a ventilating state and are to be used, it means that the vents that have a greater impact on the indoor temperature and indoor humidity are in a ventilating state. Therefore, based on the to-be-used weights corresponding to the vents that are in a ventilating state and are to be used, the to-be-used values ​​can be determined from the correspondence between the pre-set weights and the adjustment values.

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

[0135] The preset temperature interval is an interval divided based on the preset temperature, and the preset humidity interval is an interval divided based on the preset humidity; the values ​​to be used include the temperature values ​​to be used and the humidity values ​​to be used. The values ​​to be used include the temperature values ​​to be used and the humidity values ​​to be used.

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

[0137] The sum of the temperature value to be used and the preset temperature is used as the target temperature threshold, and the interval divided by the target temperature threshold is the adjusted temperature interval;

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

[0139] Since different ventilation conditions will affect the indoor temperature and indoor humidity, and thus affect the formation of condensed water, and different vents have different degrees of influence on the indoor temperature and indoor humidity, therefore, it is possible to first determine the vents to be used that have a greater impact on the indoor temperature and indoor humidity, and when the vents to be used are in a ventilating state, determine the corresponding values ​​to be used, and then adjust the pre-set temperature range and the pre-set humidity range to obtain more accurate target temperature range and target humidity range, so that the accuracy of judging whether the self-cleaning function needs to be turned off can be further improved in the future.

[0140] When the ventilation information indicates that there are no vents to be used in the ventilation state, it means that the vents that have a greater impact on the indoor temperature and indoor humidity are not in the ventilation state, and the pre-set temperature range and the pre-set humidity range do not need to be adjusted. Therefore, the pre-set temperature range can be used as the target temperature range, and the pre-set humidity range can be used as the target humidity range.

[0141] As an implementation of an embodiment of the present invention, the above-mentioned environmental adjustment information includes ventilation information and outdoor humidity, wherein the above-mentioned ventilation information is information indicating whether the vent is in a ventilation state, and the vent has a preset vent weight:

[0142] The above-mentioned step of adjusting the preset temperature interval and / or the preset humidity interval based on the environmental adjustment information to obtain the adjusted temperature interval and / or the adjusted humidity interval may include:

[0143] When the outdoor humidity is greater than a preset outdoor humidity threshold and the ventilation information indicates that there is a humidity vent in a ventilation state, a humidity adjustment value is determined based on the outdoor humidity and a correspondence between a preset humidity and a humidity value, wherein the humidity vent is a vent whose vent weight is greater than a preset weight threshold. The humidity adjustment value may be a positive number.

[0144] The preset humidity interval is adjusted based on the humidity adjustment value to obtain the adjusted humidity interval. In one embodiment, the sum of the humidity adjustment value and the preset humidity can be used as the target humidity threshold. In this way, the target humidity interval divided by the target humidity threshold can be obtained.

[0145] When the outdoor humidity is not greater than the preset humidity threshold, and / or the ventilation information indicates that there are no humidity vents in a ventilation state, it means that the outdoor humidity has a low impact on the indoor humidity. Therefore, the pre-set humidity range does not need to be adjusted and the pre-set humidity range can be used as the target humidity range.

[0146] It can be seen that in this embodiment, it can be determined whether to adjust the preset humidity range according to different situations, so as to obtain a more accurate target humidity range.

[0147] As an implementation manner of the embodiment of the present invention, the above-mentioned environmental adjustment information may include location information and weather information, wherein the weather information may be real-time weather information.

[0148] The above-mentioned step of adjusting the preset temperature interval and / or the preset humidity interval based on the environmental adjustment information to obtain the adjusted temperature interval and / or the adjusted humidity interval may include:

[0149] Based on the location information, the influence location to be used is acquired from the correspondence between the preset location and the weather influence location, wherein the influence location to be used has the preset influence weather.

[0150] The influencing weather may be weather with high temperature due to direct sunlight, so that even if the window is not opened, it will still affect the indoor temperature. Therefore, the influencing position to be used that will affect the indoor temperature may be obtained first.

[0151] When the weather information is consistent with the influencing weather, it indicates that the weather information has a greater impact on the indoor temperature. Based on the weather information, the temperature adjustment value is determined from the corresponding relationship between the pre-set weather and temperature values.

[0152] The preset temperature interval is adjusted based on the temperature adjustment value to obtain the adjusted temperature interval. In one embodiment, the sum of the temperature adjustment value and the preset temperature can be used as the target temperature threshold to obtain the target temperature interval divided by the target temperature threshold.

[0153] When the weather information is inconsistent with the influencing weather, it means that the weather information has little influence on the indoor temperature, so the pre-set temperature range may not be adjusted, and the pre-set temperature range may be used as the target temperature range. In this way, a more accurate target temperature range can be obtained.

[0154] As an implementation of an embodiment of the present invention, when the current accumulated number of self-cleaning times is less than 1, the preset number condition is to indicate that the current accumulated number of self-cleaning times is 1;

[0155] When the current accumulated number of self-cleaning times is greater than 1, the preset number condition is that the quotient of the current accumulated number of self-cleaning times and the number of times to be used is an integer. The number of times to be used can be preset, for example, the number of times to be used can be set to 1, 3, 5, etc. This is not specifically limited here.

[0156] The number of times to be used can also be determined from the correspondence between the preset quality interval and the number of times according to the quality of the condensed water. Specifically, when the current accumulated number of self-cleaning times is 1, it means that the current accumulated number of self-cleaning times meets the preset number condition, and then when the self-cleaning function is kept turned on, the number of times to be used corresponding to the quality of the condensed water can be determined from the correspondence between the preset quality interval and the number of times. In this way, more accurate self-cleaning can be achieved.
