Description

Technical Field

[0001] The present invention relates to the technical field of air handling equipment, and particularly to a control method for an air conditioner, a machine-readable storage medium, and an air conditioner. Background Art

[0002] Currently, an air conditioner generally includes a surface cooler and a cleaning device. The cleaning device includes a water tank and a spraying device for cleaning the surface cooler. Dust easily accumulates on the surface cooler of the air conditioner, and the presence of dust will reduce the heat exchange efficiency of the surface cooler, thereby affecting the air handling quality. Therefore, during the use of the air conditioner, it is necessary to regularly use the cleaning device to clean the surface cooler. Currently, the following two cleaning methods are generally adopted: one is that the user actively starts the cleaning device for cleaning according to a time period; the other is that the air conditioner starts a self-cleaning mode to self-clean the surface cooler according to a timing control logic. The timing control logic is specifically as follows: a timer starts timing from the last cleaning time, and if there is no cleaning for a long time and the set value of the timer is reached, self-cleaning is performed. However, during the flu season, blowing dust and sewage on the surface of the surface cooler and its accessories are likely to cause the growth of germs. The existing self-cleaning frequency is low and fixed, and it cannot effectively control the growth of germs on the surface dirt of the surface cooler during the flu season. Summary of the Invention

Those of ordinary skill in the art should be able to understand the specific meanings of the above terms in the present invention according to specific circumstances.

[0068] Since the actual cleaning frequency and cleanliness requirements of the surface cooler are different in different seasons or different usage scenarios. In particular, during the flu season, the dust blowing and sewage on the surface of the surface cooler and its accessories are likely to cause the growth of germs, and the actual cleaning frequency and cleanliness requirements during the flu season are relatively high. However, in the prior art, the self-cleaning frequency is fixed and low, and it cannot effectively control the growth of germs on the surface dirt of the surface cooler during the flu season.

[0069] Figure 1 is a schematic flowchart of a control method for an air conditioner according to an embodiment of the present invention, and in combination with Figures 2 - 11 , the present invention provides a control method for an air conditioner. The air conditioner 100 includes a surface cooler 110 and a self-cleaning system 130, and the self-cleaning system 130 is used to clean at least the surface cooler 110. That is to say, the self-cleaning system 130 can be only used to clean the surface cooler 110, or can be used to clean the surface cooler 110, the air conditioner box panel, the surface cooler water receiving tray, the filter or other components.

[0070] As Figure 1 shown, the control method of the air conditioner 100 may include the following steps:

[0071] Step S100, obtaining the season of the scenario where the air conditioner is located;

[0072] Step S200, determining the self-cleaning start condition according to the season.

[0073] In this embodiment, the season of the scenario where the air conditioner is located is used as a parameter for controlling the self-cleaning of the air conditioner. Different self-cleaning start conditions can be adopted in different seasons, so as to meet the different cleaning requirements of the surface cooler 110 in different seasons. Therefore, the present invention can increase the self-cleaning frequency during the flu season, effectively control the growth of germs on the surface dirt of the surface cooler 110 during the flu season, thereby preventing the germs from harming the human body and achieving the purpose of improving the user experience.

[0074] As Figure 2 shown, the control method of the air conditioner 100 may include the following steps:

[0075] Step S100, obtain the season of the scene where the air conditioner is located;

[0076] Step S300, determine the self-cleaning mode according to the season.

[0077] In this embodiment, the season of the scene where the air conditioner is located is used as a parameter for controlling the self-cleaning of the air conditioner. Different self-cleaning modes can be adopted in different seasons, so as to meet the different cleaning requirements of the surface cooler 110 in different seasons. Therefore, by using the control method of the present invention, in the influenza season, the self-cleaning can have a bactericidal performance to improve the self-cleaning cleanliness, effectively control the growth of germs on the surface dirt of the surface cooler 110 in the influenza season, thereby preventing the harm of germs to the human body and achieving the purpose of improving the user experience.

[0078] As Figure 3 shown, the control method of the air conditioner 100 may include the following steps:

[0079] Step S100, obtain the season of the scene where the air conditioner is located;

[0080] Step S200, determine the self-cleaning start condition according to the season;

[0081] Step S300, determine the self-cleaning mode according to the season.

[0082] In this embodiment, the season of the scene where the air conditioner is located is used as a parameter for controlling the self-cleaning of the air conditioner. Different self-cleaning modes and different self-cleaning start conditions can be adopted in different seasons, so as to meet the different cleaning requirements of the surface cooler 110 in different seasons. Therefore, by using the control method of the present invention, in the influenza season, the self-cleaning frequency can be increased, and the self-cleaning can have a bactericidal performance to improve the self-cleaning cleanliness, effectively control the growth of germs on the surface dirt of the surface cooler 110 in the influenza season, thereby preventing the harm of germs to the human body and achieving the purpose of improving the user experience.

[0083] In some alternative embodiments of the present invention, the control parameter of the self-cleaning start condition includes the current resistance of the surface cooler 110. Or, the control parameter of the self-cleaning start condition includes the current resistance of the surface cooler 110.

[0084] As Figure 4 shown, in some alternative embodiments of the present invention, the control method of the air conditioner 100 may include the following steps:

[0085] Step S100, obtain the season of the scene where the air conditioner is located;

[0086] Step S200, determine the self-cleaning start condition according to the season;

[0087] Step S300, determine the self-cleaning mode according to the season;

[0088] Step S400: Determine whether the air conditioner meets the self-cleaning start condition. If yes, execute step S500; if not, execute step S600.

[0089] Step S500: Control the air conditioner to operate in the self-cleaning mode, that is, control the self-cleaning system 130 to perform cleaning.

[0090] Step S600: Control the self-cleaning system 130 to standby.

[0091] In this embodiment, it is determined whether the air conditioner meets the self-cleaning start condition at least according to the current air resistance of the finned-tube heat exchanger 110.

[0092] In some alternative embodiments of the present invention, in step S100: the seasons of the scenario where the air conditioner is located are divided into the flu season and the non-flu season.

[0093] As Figure 5 shown, in some alternative embodiments of the present invention, step S300, the step of determining the self-cleaning mode according to the season may include:

[0094] Step S301: When the season is the flu season, the self-cleaning mode is the first mode, and the first mode uses the first cleaning liquid.

[0095] Step S302: When the season is the non-flu season, the self-cleaning mode is the second mode, and the second mode uses the second cleaning liquid.

[0096] In this embodiment, selecting the cleaning liquid according to the season is more conducive to improving the cleaning effect on the finned-tube heat exchanger 110, and thus more conducive to avoiding the growth of germs on the surface dirt of the finned-tube heat exchanger 110 in the flu season.

[0097] In some alternative embodiments of the present invention, the first cleaning liquid is a medicated liquid, and the second cleaning liquid is water. That is to say, the first mode is the medicated washing mode, and the second mode is the water washing mode. Specifically, when the season is the flu season, a certain amount of disinfectant is added to the water tank of the self-cleaning system 130. In this embodiment, in the flu season, a medicated liquid corresponding to the current flu germs can be selected as the first cleaning liquid, and the first cleaning liquid has the dual functions of cleaning and sterilizing, so as to further avoid the growth of germs on the surface dirt of the finned-tube heat exchanger 110 in the flu season. In the non-flu season, water is used as the second cleaning liquid to avoid the harm of drugs to the human body.

[0098] In some alternative embodiments of the present invention, both the first cleaning liquid and the second cleaning liquid are water. In this embodiment, the control method includes the step of determining the self-cleaning start condition according to the season. Different self-cleaning start conditions are adopted in different seasons so that the cleaning frequency in the flu season is higher than that in the non-flu season.

[0099] In some alternative embodiments of the present invention, when the self-cleaning mode is the first mode, the self-cleaning duration is the first duration; when the self-cleaning mode is the second mode, the self-cleaning duration is the second duration. The first duration is greater than the second duration. In this embodiment, the self-cleaning duration in the influenza season is greater than that in the non-influenza season, which can improve the cleanliness of the first mode and is more conducive to inhibiting the reproduction of influenza germs inside the air conditioner in the influenza season.

[0100] In some alternative embodiments of the present invention, both the first cleaning liquid and the second cleaning liquid are medicated liquids; the drug concentration of the first cleaning liquid is greater than that of the second cleaning liquid.

[0101] As Figure 6 described, in some alternative embodiments of the present invention, step S100, the step of obtaining the season of the scene where the air conditioner is located includes:

[0102] Step S110, obtaining an influenza risk parameter;

[0103] Step S120, determining the season of the scene where the air conditioner is located according to the influenza risk parameter.

[0104] In this embodiment, according to the influenza risk parameter, it is possible to quickly and directly determine whether the season of the scene where the air conditioner is located is the influenza season or the non-influenza season.

[0105] In some alternative embodiments of the present invention, the influenza risk parameter includes at least one of a climate influenza index, an influenza index, an AQI index, a PM2.5 index, an API index, a weather condition step number, an air humidity, and an aerosol index.

[0106] Specifically, the climate influenza index is related to the AQI index and the influenza index, rather than simply measuring the degree of reproduction of influenza virus colonies, thus making it predictive of the reproduction risk of influenza virus. The influenza index refers to the index for forecasting influenza information released by the CDC. The AQI index refers to a dimensionless index that quantitatively describes the air quality status, characterizing the current degree of air pollution. Usually, sulfur dioxide (SO2), nitrogen dioxide (NO2), fine particulate matter (PM2.5), carbon monoxide (CO), particulate matter (PM10), and ozone (O3) are used as accounting factors. The PM2.5 index, the API index, and the weather condition step number are all physical quantities characterizing air quality. API is the abbreviation of Air pollution index, and the API index refers to the air pollution index. The weather condition step number can be set according to the local weather. For example, it is set to 1 for clean, 2 for unclean, and 3 for extremely polluted, etc., so as to judge and predict the reproduction risk of influenza germs in the future air conditioner. Both air humidity and aerosol index can predict the influenza situation. This embodiment provides a specific method for obtaining the season of the scene where the air conditioner is located. By using the above method, the season of the scene where the air conditioner is located can be obtained quickly and accurately.

[0107] As Figure 7 shown, in some embodiments of the present invention, the influenza risk parameter includes the climate influenza index.

[0108] Step S110, the step of obtaining the influenza risk parameter may include:

[0109] Step S111, obtain the AQI index and the influenza index;

[0110] Step S112, obtain the climate influenza index according to the AQI index and the influenza index.

[0111] Step S120, the step of determining the season of the scene where the air conditioner is located according to the influenza risk parameter may include:

[0112] Step S121, judge whether the climate influenza index is greater than the set climate influenza index value; if so, execute step S122; if not, execute step S123;

[0113] Step S122, determine that the season of the scene where the air conditioner is located is the influenza season;

[0114] Step S123, determine that the season of the scene where the air conditioner is located is the non-influenza season.

[0115] In this embodiment, since the climate influenza index is predictive of the reproduction risk of influenza virus; therefore, in this embodiment, it is more accurate to judge whether the season of the scene where the air conditioner is located is the influenza season or the non-influenza season according to the climate influenza index.

[0116] AsFigure 8 As shown, in some alternative embodiments of the present invention, step S200, the step of determining the self-cleaning start condition according to the season may include:

[0117] Step S210, when the season is the flu season, the self-cleaning start condition is: the current air resistance of the finned-tube heat exchanger 110 is greater than the first air resistance, and / or the time difference between the current time and the most recent self-cleaning time is greater than or equal to the preset cleaning interval time;

[0118] Step S220, when the season is a non-flu season, the self-cleaning start condition is: the current air resistance of the finned-tube heat exchanger 110 is greater than the second air resistance.

[0119] Specifically, both the first air resistance and the second air resistance can be set values pre-set by the designer, or can be manually set by the user; it is also possible that the first air resistance is a floating value and the second air resistance is a set value; or both the first air resistance and the second air resistance are floating values. In this embodiment, using the air resistance of the finned-tube heat exchanger 110 as the self-cleaning start condition can clean the finned-tube heat exchanger 110 in a timely manner compared with the existing control element that only uses the time sequence as the self-starting factor.

[0120] In some alternative embodiments of the present invention, the first air resistance is equal to the second air resistance. Specifically, when different self-cleaning modes are adopted in different seasons, for example, medicated washing is adopted in the flu season and water washing is adopted in the non-flu season, the first air resistance group can be equal to the second air resistance.

[0121] In some alternative embodiments of the present invention, the first air resistance is not equal to the second air resistance. For example, the first air resistance can be less than the second air resistance, so that the self-cleaning frequency in the flu season is higher than that in the non-flu season. In this case, the same self-cleaning mode or different self-cleaning modes can be adopted in the flu season and the non-flu season.

[0122] Such as Figure 9 As shown, in some alternative embodiments of the present invention, step S200, the step of determining the self-cleaning start condition according to the season may further include: step S230, obtaining the first air resistance and / or the second air resistance at least according to the flu risk parameter.

[0123] In this embodiment, the first air resistance and / or the second air resistance can be calculated according to the flu risk parameter and the corresponding formula to obtain a dynamic judgment point, which is more conducive to running the self-cleaning mode in a timely manner in the flu season, thereby further inhibiting the reproduction of influenza bacteria inside the air conditioner and further improving the user experience.

[0124] In some alternative embodiments of the present invention, the first air resistance and the second air resistance are calculated using the same formula.

[0125] In some alternative embodiments of the present invention, according to the formula Rd2 = f2(Q), the first air resistance is calculated to obtain a floating judgment point. Specifically, Rd2 is the first air resistance, and Q is the climate influenza index. In this embodiment, the first air resistance is related to the climate influenza index, that is, the first air resistance is a floating value, which changes with the change of the climate influenza index; through the above settings, it is more conducive to timely self-cleaning of the finned tube heat exchanger 110, and at the same time, it is more conducive to inhibiting the reproduction of influenza bacteria on the finned tube heat exchanger 110.

[0126] As Figure 10 shown, in some alternative embodiments of the present invention, after step S200, the control method further includes:

[0127] Step S401, when the season is the influenza season, obtain the current air resistance of the finned tube heat exchanger 110;

[0128] Step S402, determine whether the current air resistance is greater than the first air resistance; if so, execute step S500; if not, execute step S403;

[0129] Step S500, control the air conditioner to operate in the self-cleaning mode, that is, control the self-cleaning system 130 to perform cleaning;

[0130] Step S403, obtain the time difference between the current time and the most recent self-cleaning time;

[0131] Step S404, determine whether the time difference is greater than or equal to the preset cleaning interval time; if so, execute step S500; if not, execute step S600;

[0132] Step S600, control the self-cleaning system 130 to standby.

[0133] Specifically, a differential pressure sensor is provided at the position of the finned tube heat exchanger 110. The differential pressure sensor is used to measure the pressure difference on both sides of the finned tube heat exchanger 110 to represent the air resistance of the finned tube heat exchanger 110. The method of "obtaining the current air resistance of the finned tube heat exchanger 110" is: measure the pressure difference on both sides of the finned tube heat exchanger 110. In this embodiment, in the season with a high risk of influenza, both air resistance judgment control and timing control are adopted, further ensuring the timeliness and stability of the self-cleaning control method.

[0134] In some alternative embodiments of the present invention, the influenza risk parameter is the climate influenza index.

[0135] The calculation formula of the climate influenza index is:

[0136] Q = AQI 1 / F

[0137] where Q is the climate influenza index; AQI is the air quality index; F is the influenza index.

[0138] This embodiment provides a specific algorithm for the climate influenza index. The climate influenza index is calculated based on two factors, the AQI index and the influenza index. Using the above algorithm can quickly and accurately calculate the climate influenza index.

[0139] In some alternative embodiments of the present invention, the calculation formula for the first air resistance is:

[0140]

[0141] Wherein, Q is the climate influenza index; Rd2 is the first air resistance; R end is the failure resistance of the finned-tube heat exchanger 110; Q d is the set climate influenza index value.

[0142] Specifically, the failure resistance of the finned-tube heat exchanger 110 is a fixed value obtained by testing. When the air resistance of the finned-tube heat exchanger 110 is higher than this resistance, the heat exchange performance of the finned-tube heat exchanger 110 is basically declared to fail. This embodiment provides a specific algorithm for the first air resistance. The first air resistance is calculated based on three factors, the climate influenza index, the failure resistance of the finned-tube heat exchanger 110, and the set climate influenza index value. Using the above algorithm can quickly and accurately calculate the climate influenza index.

[0143] In some alternative embodiments of the present invention, the self-cleaning system 130 includes a water tank and a medicine barrel. A medicine adding valve is provided between the medicine barrel and the water tank. When the medicine adding valve is opened, the disinfectant in the medicine barrel can be added into the water tank.

[0144] As Figure 11 shown, the control method of the air conditioner 100 may include the following steps:

[0145] Step S700, the air conditioner 100 is powered on;

[0146] Step S701, obtain the AQI index and the influenza index F;

[0147] Step S702, obtain the climate influenza index Q based on the AQI index and the influenza index F;

[0148] Step S703, determine whether the climate influenza index Q is greater than the set climate influenza index value Qd; if so, execute Step S704; if not, execute Step S713;

[0149] Step S704, determine that the season of the scene where the air conditioner is located is the influenza season;

[0150] Step S705, determine the self-cleaning mode as the medicine washing mode, and add a preset amount of disinfectant into the water tank;
