In general, the cleaning of the air conditioner filter screen mainly depends on manual operation. This way not only takes time and effort, especially when dealing with wall-mounted air conditioners, as the installation position is high, which increases the difficulty and danger of operation.

[0035] In the embodiments of the present disclosure, the smart home appliance refers to a home appliance product formed by introducing microprocessors, sensor technology, and network communication technology into a home appliance, and having the characteristics of intelligent control, intelligent sensing, and intelligent application. The operation process of the smart home appliance often depends on the application and processing of modern technologies such as the Internet of Things, the Internet, and electronic chips. For example, the smart home appliance can realize remote control and management of the smart home appliance by connecting electronic devices.

[0036] In the embodiments of the present disclosure, the terminal device refers to an electronic device with a wireless connection function. The terminal device can be connected to the Internet and communicate with the smart home appliance as described above, or can be directly connected to the smart home appliance through Bluetooth, Wi-Fi, or the like. In some embodiments, the terminal device is, for example, a mobile device, a computer, or a built-in vehicle device in a hovercar, or any combination thereof. The mobile device may, for example, include a mobile phone, a smart home device, a wearable device, a smart mobile device, a virtual reality device, or any combination thereof, wherein the wearable device may, for example, include a smart watch, a smart bracelet, a pedometer, or the like.

[0037] The present scheme discloses an air conditioner, comprising an air conditioner body, a filter screen, a micro slide rail, a micro roller sticky hair device, and a device for controlling the air conditioner. The filter screen is installed at the air inlet of the air conditioner body. The micro slide rail is installed on the surface of the filter screen. The micro roller sticky hair device is movably installed on the micro slide rail, and the outer surface of the micro roller sticky hair device is attached with a sticky sticky paper. The device for controlling the air conditioner is installed on the air conditioner body. The installation relationship described herein is not limited to being placed inside the air conditioner body, but also includes installation connection with other components of the air conditioner, including but not limited to physical connection, electrical connection, or signal transmission connection, etc. Those skilled in the art can understand that, in combination with Figure 5 and Figure 6 As shown, the device 200 (300) for controlling the air conditioner can be adapted to the available air conditioner body, and thus realize other available embodiments.

[0038] Optionally, the micro roller sticky hair device has a length of 10 mm, an outer diameter of 3 mm, and an inner diameter of 1 mm. In an example, in order to better adsorb dust on the filter screen, the surface of the micro roller sticky hair device can be attached with a sticky sticky paper, and the inner surface of the micro roller sticky hair device can be smoothly treated. In this scheme, the smooth inner surface can reduce frictional resistance, and help the micro roller sticky hair device better adhere to dust and other impurities.

[0039] Optionally, two cartridge containers are arranged on the left and right sides of the air conditioner respectively. The cartridge container arranged on the left side of the air conditioner is used to accommodate unused micro-roller lint stickers, and the cartridge container arranged on the right side of the air conditioner is used to accommodate micro-roller lint stickers that have been used and are covered with dust. As an example, the cartridge container has a length of 150 mm, a width of 30 mm, and a height of 200 mm. In this case, 10 micro-roller lint stickers can be accommodated in the length direction, 6 micro-roller lint stickers can be accommodated in the width direction, and 10 micro-roller lint stickers can be accommodated in the height direction. In this way, the cartridge container can accommodate a total of 600 micro-roller lint stickers for use when the air conditioner is running in the dust cleaning mode. Specifically, when the air conditioner is running in the dust cleaning mode, 10 micro-roller lint stickers are consumed each time. For example, if the air conditioner runs in the dust cleaning mode 6 times per year, the micro-roller lint stickers stored in the cartridge container of each air conditioner can be used for 10 years. With this scheme, the user can learn the use of the micro-roller lint stickers in time and replace them in time.

[0040] Figure 1 is a schematic diagram of a method for controlling an air conditioner provided by an embodiment of the present disclosure; in conjunction with Figure 1 As shown in the figure, the present disclosure provides a method for controlling an air conditioner, comprising:

[0041] S11, the air conditioner obtains the dust accumulation amount of the filter screen surface and the dust cleaning time length from the last time the air conditioner starts the dust cleaning mode to the current time.

[0042] S12, in the case that the dust accumulation amount of the filter screen surface meets the first dust cleaning condition and / or the dust cleaning time length meets the second dust cleaning condition, the air conditioner controls the air conditioner to start the dust cleaning mode, so as to control the stepping motor of the air conditioner to drive the micro-roller lint sticker to reciprocally roll along the micro-rail, so as to make the dust on the filter screen adhere to the outer surface of the micro-roller lint sticker.

[0043] In the present solution, the air conditioner can determine the dust accumulation amount on the filter screen surface in multiple ways. In one case, the air conditioner is associated with a pressure sensor, and the pressure values before and after the use of the filter screen can be collected by the pressure sensor. The air conditioner can take the difference between the pressure value after the use of the filter screen and the pressure value before the use of the filter screen as the dust accumulation amount on the filter screen surface. With this solution, the accurate determination of the dust accumulation amount can be achieved. In another example, the air conditioner is associated with a light scattering sensor, and the filter screen surface can be irradiated with a laser or LED light source. The dust accumulation amount on the filter screen surface can be determined by measuring the intensity of the scattered light. It can be understood that the stronger the intensity of the scattered light, the greater the dust accumulation amount on the filter screen surface. With this solution, the dust accumulation situation can be determined in real time by combining the sensitivity of the light scattering sensor to small particles. In an optimized solution, the air conditioner can also start the image sensor associated with the air conditioner when the light intensity value collected by the light scattering sensor indicates that there is dust on the filter screen surface, so as to determine the dust accumulation amount on the filter screen surface by the image features collected by the image sensor. With this solution, the accurate acquisition of the dust accumulation amount on the filter screen surface can be achieved in multiple ways.

[0044] In the present solution, the air conditioner can determine the time when the air conditioner last started the dust cleaning mode according to its use record. The air conditioner can take the time length from the time when the air conditioner last started the dust cleaning mode to the current time as the dust cleaning time length. For example, the air conditioner can determine that the time when the air conditioner last started the dust cleaning mode is 12 o'clock on January 20 according to its use record, and the current time is 12 o'clock on January 22. Then, the time length from the time when the air conditioner last started the dust cleaning mode to the current time can be taken as the dust cleaning time length, which is 2 days. With this solution, the accurate determination of the dust cleaning time length can be achieved.

[0045] Further, the air conditioner can determine the starting time of the dust cleaning mode in three ways. In one case, the air conditioner controls the air conditioner to start the dust cleaning mode when the dust accumulation amount on the filter screen surface meets the first dust cleaning condition. In another case, the air conditioner controls the air conditioner to start the dust cleaning mode when the dust cleaning time length meets the second dust cleaning condition. In an optimized solution, the air conditioner controls the air conditioner to start the dust cleaning mode when the dust accumulation amount on the filter screen surface meets the first dust cleaning condition and the dust cleaning time length meets the second dust cleaning condition. With this solution, the starting time of the dust cleaning mode can be accurately determined in three ways. In this way, the air conditioner can control the stepping motor of the air conditioner to drive the micro-roller lint roller to reciprocate along the micro-rail through the transmission module when the dust cleaning mode is started, so as to make the dust on the filter screen adhere to the outer surface of the micro-roller lint roller. In this way, not only the automation and efficiency of filter screen cleaning are achieved, but also the filter screen is protected from damage, the maintenance cost is reduced, and the air quality and user experience are improved.

[0046] The method for controlling an air conditioner provided in the embodiment of the present disclosure can intelligently start the dust cleaning mode by monitoring the dust accumulation amount on the filter screen surface and the dust cleaning time, accurately remove the dust on the filter screen by using the stepping motor to drive the micro-roller lint remover, effectively prevent dust from drifting, significantly improve the cleaning efficiency and indoor air quality, and bring a more healthy and convenient air conditioner use experience to the user.

[0047] Figure 2 is a schematic diagram of a method for determining that the dust accumulation amount on the filter screen surface meets the first dust cleaning condition provided in the embodiment of the present disclosure; in combination with Figure 2 As shown in the figure, the dust accumulation amount on the filter screen surface meeting the first dust cleaning condition can be determined by the following method:

[0048] S21, the air conditioner determines the dust standard amount and the dust deviation amount.

[0049] S22, the air conditioner determines the dust cleaning range according to the dust standard amount and the dust deviation amount.

[0050] S23, in the case that the dust accumulation amount on the filter screen surface is within the dust cleaning range, the air conditioner determines that the dust accumulation amount on the filter screen surface meets the first dust cleaning condition.

[0051] In the present scheme, the air conditioner can determine the dust standard amount in various ways. In one example, the dust content threshold value set for each air conditioner can be obtained in combination with the set value of the self-cleaning mode of the air conditioner in the region where the air conditioner is located, and the average value of the dust content threshold value set for each air conditioner is taken as the dust standard amount. The region where the air conditioner is located can be the city where the air conditioner is located or the community where the air conditioner is located. In this way, the dust standard amount can be set in combination with the threshold value setting of other air conditioners in the region where the air conditioner is located, so that the setting of the dust standard amount conforms to the use standard of the air conditioner in the region. In another example, the air conditioner determines the dust standard amount, including: the air conditioner determines the model of the air conditioner and the environmental parameter value of the indoor where the air conditioner is located. The air conditioner determines the dust content matched with the model of the air conditioner and the environmental parameter value of the indoor where the air conditioner is located as the dust standard amount according to a preset corresponding relationship. With this scheme, the dust standard amount can be accurately determined in combination with the model of the air conditioner and the environmental parameter value of the indoor where the air conditioner is located.

[0052] In the present scheme, the dust deviation amount can be set in advance. For example, the dust deviation amount can be ±(10%×dust standard amount). In an optimized scheme, the user can also customize the dust deviation amount in combination with the filter screen cleaning standard of the air conditioner. With this scheme, the dust deviation amount can be accurately determined.

[0053] Further, the air conditioner can determine the dust cleaning range according to the dust standard amount and the dust deviation amount. Specifically, the dust cleaning range is [dust standard amount-dust deviation amount, dust standard amount+dust deviation amount]. With this scheme, the accurate determination of the dust cleaning range can be realized.

[0054] Further, the air conditioner can determine that the dust accumulation amount of the filter screen surface satisfies the first dust cleaning condition when the dust accumulation amount of the filter screen surface is within the dust cleaning range. With this scheme, the starting time of the dust cleaning mode can be accurately determined in combination with the dust accumulation state of the filter screen surface.

[0055] Optionally, in S21, the air conditioner determines the dust standard amount, including:

[0056] The air conditioner determines the model of the air conditioner and the environmental parameter value of the indoor environment where the air conditioner is located.

[0057] The air conditioner determines the dust standard amount according to a preset corresponding relationship between the model of the air conditioner and the environmental parameter value of the indoor environment where the air conditioner is located.

[0058] It can be understood that the filter screen size, filtering efficiency and operating power of air conditioners of different models are all different, and the environmental parameter value of the indoor environment where the air conditioner is located also affects the generation and deposition speed of dust. Here, the environmental parameter value of the indoor environment where the air conditioner is located includes but is not limited to environmental temperature, environmental humidity and air quality. Therefore, researchers can test the dust deposition rules of different models of air conditioners under different environmental parameters in the laboratory to generate a corresponding relationship between the model of the air conditioner, the environmental parameter value of the indoor environment where the air conditioner is located and the dust standard amount, so as to ensure that the corresponding relationship can adapt to different situations.

[0059] In this way, the air conditioner can determine the model of the air conditioner in combination with its installation information, and obtain the environmental parameter value of the indoor environment where the air conditioner is located in combination with the environmental parameter sensor associated with the air conditioner. With this scheme, the model of the air conditioner and the environmental parameter value of the indoor environment where the air conditioner is located can be accurately obtained.

[0060] Further, the air conditioner can determine the dust standard amount according to a preset corresponding relationship between the model of the air conditioner and the environmental parameter value of the indoor environment where the air conditioner is located. With this scheme, the dust standard amount can be accurately determined in combination with the model of the air conditioner and the environmental parameter value of the indoor environment where the air conditioner is located.

[0061] Figure 3 is a schematic diagram of a method for determining that the dust cleaning duration satisfies the second dust cleaning condition provided by the embodiments of the present disclosure; in combination with Figure 3 As shown in FIG. 8, the dust cleaning duration satisfies the second dust cleaning condition when the dust accumulation amount of the filter screen surface is within the dust cleaning range.

[0062] S31, the air conditioner acquires the current dust accumulation amount, the environmental parameter value, and the air conditioner use information of the user.

[0063] S32, the air conditioner determines the target dust cleaning period according to the current dust accumulation amount, the environmental parameter value, and the air conditioner use information of the user.

[0064] S33, in the case where the dust cleaning duration reaches the target dust cleaning period, the air conditioner determines that the dust cleaning duration satisfies the second dust cleaning condition.

[0065] In the scheme, the environmental parameter value includes but is not limited to the environmental temperature, the environmental humidity, and the air quality. The environmental parameter value can be acquired through the environmental parameter sensor associated with the air conditioner. The air conditioner use information of the user can be the use frequency of the air conditioner, the operation mode, and the use time period of the air conditioner, etc. The air conditioner use information can be extracted through the historical operation information of the air conditioner. With the scheme, the current dust accumulation amount, the environmental parameter value, and the air conditioner use information of the user can be acquired.

[0066] Optionally, the target dust cleaning period can be set in advance. As an example, the target dust cleaning period can be 60 days. In an optimized scheme, the air conditioner can also determine the target dust cleaning period in combination with the current dust accumulation amount, the environmental parameter value, and the air conditioner use information of the user. With the scheme, the accurate determination of the target dust cleaning period can be realized.

[0067] Further, in the case where the dust cleaning duration reaches the target dust cleaning period, the air conditioner can determine that the dust cleaning duration satisfies the second dust cleaning condition. With the scheme, the starting time of the dust cleaning mode can be accurately determined in combination with the dust cleaning duration.

[0068] Optionally, S32, the air conditioner determines the target dust cleaning period according to the current dust accumulation amount, the environmental parameter value, and the air conditioner use information of the user, including:

[0069] The air conditioner inputs the current dust accumulation amount, the environmental parameter value, and the air conditioner use information of the user into a prediction model for predicting the dust accumulation speed, to obtain the dust accumulation speed output by the prediction model.

[0070] The air conditioner determines the target dust cleaning period according to the dust accumulation speed.

[0071] In this solution, the air conditioner can pre-build a prediction model for predicting the dust accumulation speed. Specifically, the historical dust accumulation amount, environmental parameter values, and user air conditioner usage information in a historical time period can be obtained, and the collected historical data can be cleaned to remove outliers, missing values, and duplicate data. Then, the air conditioner can perform standardization or normalization processing on the historical data to ensure that data of different dimensions can be compared on the same scale. At the same time, the air conditioner can select a machine learning algorithm for model training. Here, the machine learning algorithm includes but is not limited to linear regression, random forest regression, gradient boosting tree, and the like. In this way, the processed historical data can be used as a training set to train the selected machine model, and by adjusting the model parameters, a trained prediction model for predicting the dust accumulation speed can be obtained. With this solution, the prediction model for predicting the dust accumulation speed can be accurately obtained.

[0072] Further, the air conditioner can input the current dust accumulation amount, environmental parameter values, and user air conditioner usage information into the prediction model for predicting the dust accumulation speed to obtain the dust accumulation speed output by the prediction model. With this solution, the dust accumulation speed can be effectively determined.

[0073] It can be understood that the faster the dust accumulation speed, the more frequently the cleaning mode needs to be started, and the shorter the cleaning period. Therefore, the corresponding relationship between the dust accumulation speed and the cleaning period can be pre-stored in combination with the inverse proportional relationship rule of the cleaning period and the dust accumulation speed. In this way, after obtaining the dust accumulation speed output by the prediction model, the cleaning period corresponding to the dust accumulation speed can be matched in the pre-stored corresponding relationship as the target cleaning period. With this solution, the target cleaning period can be accurately determined.

[0074] Figure 4 is a schematic diagram of a method provided by an embodiment of the present disclosure for obtaining the dust accumulation amount of the filter screen surface and the cleaning duration of the air conditioner from the previous time of starting the cleaning mode to the current time; in combination with Figure 4 As shown in FIG. 11, optionally, S11, the air conditioner obtains the dust accumulation amount of the filter screen surface and the cleaning duration of the air conditioner from the previous time of starting the cleaning mode to the current time, including:

[0075] S41, the air conditioner obtains the current time.

[0076] S42, in the case that the current time is in the away-from-home period, the air conditioner obtains the dust accumulation amount of the filter screen surface and the cleaning duration of the air conditioner from the previous time of starting the cleaning mode to the current time.

[0077] It can be understood that considering that the air conditioner cleaning process can generate noise which has a negative impact on the user experience effect, therefore, the cleaning strategy of the case can be used during the user's away-from-home period. Among them, the away-from-home period can be pre-stored in the air conditioner. For example, the away-from-home period can be 9:00 to 21:00. In an optimized scheme, the away-from-home period can also be generated in combination with the away-from-home rules of different family members. With this scheme, accurate determination of the away-from-home period can be achieved.

[0078] In the present scheme, the air conditioner can determine the current time through its associated timing module. And in the case that the current time is in the away-from-home period, the dust accumulation amount of the filter surface and the dust cleaning time length from the previous start of the air conditioner cleaning mode to the current time are obtained. With this scheme, the necessary cleaning operation can be autonomously judged and executed according to the preset cleaning logic and conditions when the user is not at home. Not only can it ensure that the air conditioner filter screen always maintains a high degree of cleanliness, thereby maintaining the best operating efficiency of the air conditioner, but also can effectively avoid the inconvenience of noise or dust drifting caused by cleaning operation before the user returns home. It brings a more worry-free and efficient use experience to the user.

[0079] Optionally, after controlling the air conditioner to start the cleaning mode, the method further comprises:

[0080] The air conditioner monitors the operating state of the cleaning-related device.

[0081] In the case that the operating state of the cleaning-related device is an abnormal state, the air conditioner pushes a prompt information to the user to remind the user to timely repair or replace the cleaning-related device.

[0082] In the present scheme, the cleaning-related device includes a micro slide rail, a micro roller lint stick and a stepping motor. Specifically, the air conditioner can collect image information of different devices through its associated image sensor to determine the operating state of the cleaning-related device. Here, the operating state can be a normal state or an abnormal state. Further, in the case that the operating state of the cleaning-related device is an abnormal state, the air conditioner pushes a prompt information to the user to remind the user to timely repair or replace the cleaning-related device. With this scheme, the user can be sent a repair or replacement reminder as soon as an abnormality is found, effectively ensuring the stable operation of the air conditioner cleaning mode and improving the convenience of user maintenance and the reliability of the equipment.

[0083] Optionally, the air conditioner is also provided with a quantity monitoring device. The quantity monitoring device is configured to monitor the number of micro roller lint sticks in each magazine type container in real time and accurately. Specifically, the air conditioner controls the air conditioner to start the cleaning mode, and also includes:

[0084] The air conditioner automatically reduces the number of micro roller lint sticks in the left magazine type container to reflect the consumption of the lint stick; or,

[0085] The air conditioner automatically increases the number of the right side cartridge type container micro-roller lint roller as a mark of the lint roller recycling or preparation for reuse.

[0086] In this scheme, if it is monitored that the number of the micro-roller lint roller in the cartridge type container on either side does not change as expected, it is determined that there may be an operation anomaly or equipment failure, and the air conditioner immediately issues a failure maintenance reminder so that the user or maintenance personnel can intervene in time.

[0087] Optionally, the air conditioner is also provided with a quality monitoring module, which can evaluate the dust removal effect by accurately measuring the weight change of the filter screen before and after the dust removal treatment. Specifically, if the weight of the filter screen decreases by less than a preset threshold after the first dust removal treatment, the air conditioner automatically triggers a secondary dust removal treatment to attempt to further remove dust on the filter screen. Here, the preset threshold can be set to 50% of the original weight of the filter screen.

[0088] Further, if the weight of the filter screen after the secondary dust removal treatment is still less than the preset threshold compared with the first dust removal, the air conditioner issues a failure warning. In this scheme, it is convenient to inform the user that the micro-roller lint roller has weakened or failed, resulting in poor dust removal effect.

[0089] The embodiments of the present disclosure also provide a method for controlling an air conditioner, comprising:

[0090] The air conditioner obtains the rotating speed of the air conditioner fan.

[0091] The air conditioner determines the target transmission speed of the micro-roller according to the rotating speed of the air conditioner fan.

[0092] The air conditioner controls the air conditioner fan according to the target transmission speed to improve the dust removal effect of the air conditioner.

[0093] It can be understood that the dust cleaning effect of the micro roller lint roller on the filter screen is related to the air flow speed around it, the faster the air flow speed, the worse the dust cleaning effect. The air flow speed around the filter screen is positively correlated with the fan speed of the motor, the faster the fan speed, the greater the air flow speed. Therefore, the target transmission speed of the micro slide rail can be determined in combination with the speed of the air conditioner fan. Specifically, the air conditioner determines the target transmission speed of the micro slide rail according to the speed of the air conditioner fan, including: in the case that the speed of the air conditioner fan is less than the first speed, the air conditioner determines the target transmission speed of the micro slide rail as the first speed. In the case that the speed of the air conditioner fan is greater than or equal to the first speed and less than the second speed, the air conditioner determines the target transmission speed of the micro slide rail as the second speed. In the case that the speed of the air conditioner fan is greater than the second speed, the air conditioner determines the target transmission speed of the micro slide rail as the third speed. Wherein, the first speed > the second speed > the third speed. As an example, the first speed is 300 r / min, the second speed is 600 r / min, the first speed is 0.75 turns / min, the second speed is 0.5 turns / min, and the third speed is 0 turns / min. With this scheme, the target transmission speed of the micro slide rail can be accurately determined in combination with the speed of the air conditioner fan. Further, the air conditioner can control the air conditioner fan according to the target transmission speed to improve the dust cleaning effect of the air conditioner. With this scheme, when the fan speed is low, the micro slide rail transmission speed can be slowed down to 0.75 turns / min, effectively utilizing the slow air flow speed and enhancing the dust adsorption capacity of the lint roller, thereby improving the dust cleaning effect. And when the fan speed increases to a medium range, the air flow speed is determined to increase, and the micro slide rail transmission speed is automatically reduced to 0.50 turns / min, balancing the air flow speed and the working efficiency of the lint roller, and maintaining good dust cleaning performance. Further, when the fan speed is too high and the air flow speed is too fast, the lint roller cleaning effect is significantly reduced, and the cleaning process is automatically stopped to avoid invalid operation and resource waste.

[0094] In an optimized scheme, when the air conditioner is not started, the air around the filter screen does not flow or has a small flow rate, so the air flow has little effect on the lint roller and the dust cleaning effect is good. The micro slide rail is controlled to run at 1 turn / min to ensure the dust cleaning effect of the dust cleaning mode.

[0095] In an optimized scheme, the air conditioner remote controller also has a dust cleaning mode button. In this way, during actual use of the air conditioner, the user can perform dust cleaning treatment on the filter screen of the air conditioner according to personal will.

[0096] It should be noted that the manual operation mode has higher priority than the automatic operation mode and can be started at any time point. With this scheme, by setting the manual operation mode to have higher priority than the automatic operation mode, flexibility and immediacy of air conditioner operation are achieved. This design allows the user to directly intervene and start the manual operation mode at any time point without waiting or being limited by the preset conditions and timing of the automatic operation mode. This priority setting not only enhances the controllability and response speed of the system, but also provides the user with the ability to quickly and effectively adjust the air conditioner state in the face of unexpected situations or specific needs.
