Wherein, the reference time is a time point when the air conditioner performs filter screen cleaning last time. After the standby time of the air conditioner is greater than the first threshold and the filter screen cleaning operation is completed, the standby time is recalculated. After the running time of the air conditioner is greater than the second threshold and the filter screen cleaning operation is completed, the running time is recalculated.

By adopting the method for cleaning the filter screen of an air conditioner provided by the embodiment of the present disclosure, the air conditioner obtains the standby time and the running time. If the standby duration is greater than the first threshold, it means that the standby duration of the air conditioner is relatively long, and the air conditioner has not been used for a long time, resulting in dust accumulation on the filter screen. If the running time is greater than the second threshold, it means that the air conditioner is running for a long time, and the filter screen is dirty and clogged due to long-term use. In the case of the above two types of dirty clogging, the air conditioner performs a corresponding filter cleaning operation according to the latest reference time of filter cleaning. The filter screen of the air conditioner can be cleaned in time both in the standby state and the running state, and the cleaning effect of the filter screen is improved.

In this way, in a case where the time difference between the reference time and the current time is greater than or equal to the first difference threshold, it means that the latest time point of cleaning the filter screen of the air conditioner is far from the current time. The air conditioner performs the corresponding filter cleaning operation according to the time difference. It avoids the time point when the air conditioner cleans the filter screen when it is in standby and the time point when the air conditioner cleans the filter screen when the air conditioner is running. The energy consumption of the air conditioner for filter cleaning is reduced.

Optionally, the air conditioner performs a corresponding filter screen cleaning operation according to the time difference, including: the air conditioner determines the first cycle rotation times of the filter screen corresponding to the time difference according to the first relationship; If it is less than the second difference threshold, the first cycle rotation number is determined as the target cycle rotation number; when the time difference is greater than or equal to the second difference threshold, the air conditioner, according to the first cycle rotation number and the latest The number of cycle rotations for filter screen cleaning determines the target number of cycle rotations; the air conditioner cleans the filter screen according to the target cycle number of rotations.

The cleaning time of the filter screen is adapted to the time difference, and the cleaning effect of the filter screen is improved. In the case that the time difference is less than the second difference threshold, the last time the filter was cleaned is relatively close to the current time, and it is only necessary to clean the filter according to the number of rotations in the first cycle. In the case that the time difference is greater than or equal to the second difference threshold, the time point of the last filter screen cleaning is relatively far from the current time point, and the number of rotations of the first cycle of the latest filter screen cleaning is compared to the number of rotations of the first cycle Compensation is performed to determine the number of target cycle rotations. The air conditioner performs filter cleaning according to the target number of cycles. The duration and time difference of filter screen cleaning are more adaptable, and the effect of filter screen cleaning is improved.

As shown in FIG. 12 , an embodiment of the present disclosure provides a method for cleaning a filter screen of an air conditioner, including:

S121. The air conditioner acquires its own standby time.

S122. The air conditioner determines whether the standby duration is less than a standby duration threshold. If not, execute S123. If yes, execute S124.

S123, the air conditioner detects the light transmittance of the filter screen.

S124, the air conditioner sets the last time of cleaning the filter screen as the reference time.

S125, the air conditioner judges whether the difference between the current time and the reference time is smaller than the difference threshold. If not, execute S123. If yes, execute S124.

S126, the air conditioner turns on the cleaning component when the light transmittance is less than or equal to the set threshold.

S127, the air conditioner controls the filter screen to circulate and rotate.

By adopting the method for cleaning the filter screen of an air conditioner provided by the embodiments of the present disclosure, the increase in energy consumption caused by frequent detection of light transmittance can be reduced. Considering the frequency of use of the user's air conditioner, the air conditioner will automatically detect the cleanliness of the filter once the user has not used the air conditioner for a set period of time. For example, if the user does not turn on the air conditioner for 20 consecutive days, the air conditioner will check the cleanliness of the filter once. The purpose of cleaning the filter screen of the air conditioner in standby is to realize regular cleaning, and at the same time, it can also ensure the renewal of the liquid circulation in the liquid storage device. In the case that the user frequently uses the air conditioner, it will inevitably cause an increase in filter dust. Therefore, when the cumulative running time of the calculated air conditioner reaches the difference threshold, the cleanliness of the filter screen is detected once. For example, every time the air conditioner runs for 100 cumulative hours, the air conditioner will check the cleanliness of the filter screen once. At the same time, the regular cleaning of the accumulated standby time also takes into account the situation that the user occasionally turns on the air conditioner and then waits for a long time. Since the air quality in each area is different, when the light transmittance of the filter screen does not need to be cleaned for multiple consecutive detections, the difference threshold can be increased accordingly. The method of increasing may be to set the time since the last filter cleaning and the accumulated air-conditioning running time between this filter cleaning as the difference threshold, or it may be set by the user.

Optionally, the air conditioner turns on the cleaning component when the light transmittance is less than or equal to the set threshold, including: the air conditioner controls the water storage tank to operate in a self-heating mode when the light transmittance is less than or equal to the set threshold Until the preheating conditions are met; the air conditioner opens the cleaning nozzles when the preheating conditions are met; the air conditioner controls the cleaning nozzles to operate in self-heating mode, raising the liquid temperature to the cleaning temperature. In this way, the cleaning efficiency and cleanliness of the filter screen cleaning can be improved. Due to the presence of lubricating oil and other substances inside the air conditioner, it is difficult to remove the sundries on the filter screen, and high-temperature cleaning can reduce the difficulty of cleaning to a certain extent. Therefore, through the self-heating function of the cleaning nozzle, dense high-temperature and high-pressure liquid can be sprayed to clean the filter screen, which effectively improves the efficiency of filter screen cleaning. At the same time, the high temperature and humid hot water vapor produced by the high temperature can sterilize the filter screen.

Optionally, when the difference between the current time of the air conditioner and the reference time is less than the difference threshold, the duration of the air conditioner being turned on is acquired. When the opening time is greater than or equal to the liquid collection time, the air conditioner controls the water pump to start to collect the condensed water generated by the air conditioner to the water storage tank. In this way, the condensed water can be collected through the forward rotation of the water pump for cleaning the filter screen, so as to realize the secondary utilization of energy.

Optionally, the air conditioner controlling the cyclic rotation of the filter screen includes: the air conditioner determines the target cyclic rotation times of the filter screen corresponding to the light transmittance; the air conditioner controls the cyclic rotation of the filter screen according to the target cyclic rotation times. In this way, the cleanliness of the filter screen can be improved. By detecting the light transmittance of the filter screen, the number of rotations required for the current cleaning is determined to ensure that the cleanliness of the filter screen after cleaning can meet expectations.

Optionally, the air conditioner acquires the cumulative running time of the air conditioner after the filter screen cleaning process ends. When the accumulated operating time reaches the re-inspection time, the air conditioner detects the new light transmittance of the filter. When the new light transmittance is greater than the set threshold, the air conditioner is controlled to operate normally. In the case that the new light transmittance is less than or equal to the set threshold, the air conditioner sets the new light transmittance as the set threshold and reminds the user. In this way, the moisture on the filter screen is blown dry after the air conditioner runs normally for a period of time, and then the light transmittance of the filter screen is tested again to ensure the accuracy of light transmittance detection.

Optionally, when the air conditioner is running, the ratio value of the water to the volume of the water storage tank is periodically detected. If the ratio value is less than or equal to the ratio threshold, the user is prompted to add water to the water storage tank. In this way, it can be ensured that there is sufficient water in the water storage tank when the filter screen cleaning process is started.
