[0002] As consumers pay more and more attention to health, air purification functions have gradually become a standard feature in electrical appliances (such as air conditioners).

[0003] Appliances with air purification functions are generally equipped with pollutant detection devices and corresponding purification devices. The detection device measures pollutant concentrations to determine if purification is necessary, and the purification device then cleans the indoor air. Current purification devices typically include ultraviolet (UVC), high-efficiency particulate air (HEPA) filters, and ion purification. UVC is harmful to humans, HEPA filters require regular replacement and cannot be used long-term, and ion purification requires an external discharge device, which is costly.

[0025] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0026] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments.

It should be understood that such data can be interchanged where appropriate for the embodiments of this application described herein.

[0028] It should be understood that when an element (such as a layer, film, region, or substrate) is described as being "on" another element, the element may be directly on the other element, or there may be an intermediate element present. Furthermore, in the specification and claims, when an element is described as being "connected" to another element, the element may be "directly connected" to the other element, or "connected" to the other element via a third element.

[0029] As described in the background section, existing pollutant purification devices generally include ultraviolet (UVC), high-efficiency particulate air (HEPA) filters, and ion purification. UVC is harmful to the human body, HEPA filters need to be replaced regularly and cannot be used for a long time, and ion purification requires an external discharge device, which is costly. To solve the problem that existing technologies cannot purify indoor air environment by using only electrical appliances, embodiments of this application provide an air purification method, device, computer-readable storage medium, and electrical appliances.

[0030] Figure 1 This is a schematic flowchart of an air purification method according to an embodiment of this application, as shown below. Figure 1As shown, the method includes the following steps:

[0031] Step S101, obtaining the types of indoor pollutants and the concentrations of the above-mentioned indoor pollutants, where the above-mentioned indoor pollutants are pollutants in the air within the preset space where the electrical appliance is located;

[0032] Step S102, controlling the electrical appliance to turn on the purification function to purify the air within the preset space according to the type of the above-mentioned indoor pollutants, and / or the concentration of the above-mentioned indoor pollutants.

[0033] Before performing the above steps, the electrical appliance needs to be powered on and run. In actual applications, the purification function can be manually turned on by the user. For example, the user can use a remote control to turn on the purification function of the electrical appliance.

[0034] Indoor pollutants, especially microorganisms such as bacteria and viruses, cannot exist independently in the indoor air in a single form. Generally, they need to exist in the form of aerosols or attached to carriers such as particulate matter. The particulate pollutants in the indoor air can also become the condensation nuclei of water vapor, causing the water vapor to condense into droplets, increasing the diameter (mass), and even settling, which is also the principle of wet dust removal. On the other hand, the particulate matter and the moisture in the indoor air will also form aggregates due to surface tension and other effects. Therefore, moisture is an important carrier of indoor pollutants.

[0035] To better determine whether to turn on the purification function of the electrical appliance, there are various types of the above-mentioned indoor pollutants. Controlling the electrical appliance to turn on the purification function to purify the air within the preset space according to the type of the above-mentioned indoor pollutants, and / or the concentration of the above-mentioned indoor pollutants, includes: when the type of the above-mentioned indoor pollutants and the concentration of the above-mentioned indoor pollutants meet the first condition, controlling the electrical appliance to turn on the above-mentioned purification function to purify the air within the preset space, where the above-mentioned first condition is that the concentration of at least one type of the above-mentioned indoor pollutants is greater than or equal to the preset concentration.

[0036] Specifically, the types of the above-mentioned indoor pollutants include particulate pollutants C such as PM2.5 and PM0.3, gaseous pollutant concentrations P such as formaldehyde, VOC (volatile organic compounds), and odors, and harmful microorganism concentrations M such as bacteria and viruses. When C < C0 and P < P0 and M < M0, it is judged as no, indicating that the indoor air is clean and there is no need for air purification, and the air conditioner operates normally. The above normal operation means that the air conditioner performs common functions such as refrigeration and heating based on user instructions. Among them, C0 is the judgment standard value of the particulate pollutant concentration, preferably 0 < C0 ≤ 0.035 mg / m 3 . P0 is the judgment standard value of the gaseous pollutant concentration, preferably 0 < P0 ≤ 0.03 mg / m 3M0 is the standard value for judging the concentration of microbial contaminants, preferably 0. <M0≤1000CFU / m 3 When C0≥C, P0≥P, or M0≥M, it is determined that the indoor air is polluted and needs to be purified. The air conditioner will then activate its purification function and proceed to the next step.

[0037] The specific process is as follows: Figure 2 As shown, after the air conditioner is powered on, the indoor pollutant concentration is detected and determined, and it is determined whether purification is needed. If purification is determined, the indoor environmental parameters (e.g., humidity parameters) are adjusted based on the pollutant type and concentration. Then, the air conditioner purification parameters are determined based on the pollutant type and concentration. Finally, the air conditioner is controlled to run the purification mode according to the corresponding parameters. Finally, the purification mode is ended and the air conditioner returns to normal operation.

[0038] In one instance, such as Figure 3 As shown, if the indoor environmental parameters meet the requirements (e.g., the humidity parameter is high enough), it is not necessary to adjust the indoor environmental parameters and determine the air conditioner purification parameters. The air conditioner can be directly controlled to run the purification mode according to the corresponding parameters, and finally the purification mode is ended and the air conditioner runs normally.

[0039] In an optional embodiment, the method can also purify the internal environment of the appliance, and the specific implementation steps are as follows:

[0040] Step S201: Obtain the type and concentration of the internal contaminants, wherein the internal contaminants are contaminants inside the electrical appliance.

[0041] Step S202: Based on the type of pollutants inside the machine and / or the concentration of the pollutants inside the machine, control the electrical appliance to activate the purification function to purify the internal environment of the electrical appliance.

[0042] Specifically, the types of pollutants inside the unit include the surface dirt C' of the air conditioner's internal heat exchanger and air ducts, the surface microbial growth M', and the concentration of gaseous pollutants such as odors P'. The degree of surface dirt C' is indirectly determined by combining the cumulative operating time t' of the air conditioner and the corresponding average indoor pollutant concentration c, i.e., C' = f(t', c). In particular, C' = k × t' × c. k is the pollutant deposition coefficient, characterizing the degree of contamination of the internal surfaces caused by pollutant deposition. The cumulative operating time t' can be determined by the operating time of the air conditioner motor, and the average indoor pollutant concentration c is obtained by real-time or timed detection and calculation of the corresponding average value by indoor pollutant sensors.

[0043] Among them, the growth situation of the above microorganisms can be detected by devices and sensors with the ability to detect surface microorganisms, such as a fluorescence microorganism detector. The above pollution situations such as surface dirt and mold microorganism growth can also be directly determined by the cumulative operation duration or the interval duration since the last self-cleaning, or the effect of the present invention can also be achieved by visual technologies such as a camera for intuitive judgment. The concentration of the above gaseous pollutants is detected by an odor sensor, a formaldehyde sensor, etc.

[0044] In order to more accurately determine whether to activate the purification function of the electrical appliance, there are various types of pollutants inside the above electrical appliance. According to the type of the pollutants inside the above electrical appliance, and / or, the concentration of the pollutants inside the above electrical appliance, control the above electrical appliance to activate the above purification function to purify the internal environment of the above electrical appliance, including: when the type of the pollutants inside the above electrical appliance and the concentration of the pollutants inside the above electrical appliance meet the second condition, control the above electrical appliance to activate the above purification function to purify the internal environment of the above electrical appliance, where the above second condition is that the concentration of at least one type of the pollutants inside the above electrical appliance is greater than or equal to a preset concentration.

[0045] Specifically, when C’ < C’0 and P’ < P’0 and M’ < M’0, it is judged as no, indicating that the cumulative operation time of the air conditioner is not long or the air quality is good, and there is no obvious pollution inside the machine, so relevant cleaning and purification can be not carried out; when C’ ≥ C’0 or P’ ≥ P’0 or M’ ≥ M’0, it is judged as yes, indicating that the air conditioner has been running for a long time or the indoor air quality is poor, and the probability of pollution inside the machine is high, and relevant programs need to be run as soon as possible for cleaning and purification to ensure the healthy use of users.

[0046] Similarly, this method can not only purify the air in the above preset space and the internal environment of the above electrical appliance separately, but also purify both at the same time. That is, there are various types of indoor pollutants, and there are various types of pollutants inside the above electrical appliance. The above method further includes: when the type and concentration of the indoor pollutants and the type and concentration of the pollutants inside the above electrical appliance meet the third condition, control the above electrical appliance to activate the purification function to purify the air in the above preset space and the internal environment of the above electrical appliance, where the above third condition is that the concentration of at least one type of the indoor pollutants is greater than or equal to a preset concentration, and the concentration of at least one type of the pollutants inside the above electrical appliance is greater than or equal to a preset concentration. Correspondingly, the judgment condition for whether to activate the purification function is: when C < C0 and P < P0 and M < M0 and C’ < C’0 and P’ < P’0 and M’ < M’0, it is judged as no, and when C0 ≥ C or P0 ≥ P or M0 ≥ M or C’ ≥ C’0 or P’ ≥ P’0 or M’ ≥ M’0, it is judged as yes. All possible logical judgment situations are included in the above method, and no examples are given here one by one.

[0047] Meanwhile, the air conditioner optimizes the purification process and time based on the type and concentration of target pollutants, improving the purification effect while reducing the purification cycle, creating a more intelligent and healthy living environment for consumers. Before purifying the air in the aforementioned preset space and / or the internal environment of the aforementioned appliances, the method further includes: determining the processing method of the purification function based on the type and concentration of the aforementioned indoor pollutants, and / or the type and concentration of the aforementioned internal pollutants, wherein the processing method includes at least one of the following: humidity treatment, condensation treatment, frosting treatment, defrosting treatment, drying treatment, and high temperature treatment; obtaining relevant parameters of the aforementioned processing method, wherein the relevant parameters are parameters affecting the processing time of the aforementioned processing method; and determining the processing time of the aforementioned processing method based on the type and concentration of the aforementioned indoor pollutants, and / or the type and concentration of the aforementioned internal pollutants and the aforementioned relevant parameters.

[0048] In order to achieve indoor air purification by water washing using only the advantages of the appliance itself without the need for wastewater treatment or other operations, and without the need for consumable replacement, thus saving manufacturing costs, the appliance is an air conditioner. The air conditioner includes a heat exchanger. In the case of condensation, water droplets are attached to the surface of the heat exchanger. In the case of frost, frost crystals are attached to the surface of the heat exchanger.

[0049] As a crucial component of air conditioning systems, the impact of dust accumulation on heat exchangers is undeniable. However, fundamentally, dust accumulation on the heat exchanger surface is essentially the deposition of airborne particulate matter. While dust accumulation on the heat exchanger surface does significantly degrade air conditioner performance, it also serves as a highly efficient device for collecting and purifying dust and other particulate pollutants, functioning similarly to HEPA filters. By optimizing the heat exchanger's pollutant collection capacity and addressing its cleaning issues, indoor air purification can be achieved. Furthermore, due to the louvered, fan-shaped structure of the heat exchanger, the reduced gaps between the blades when water droplets and frost crystals adhere to the fins allow for better pollutant capture.

[0050] Wet dust removal is a traditional technology that uses water as a purification medium to remove pollutants. In recent years, many air conditioner manufacturers have also tried to use water to purify filters or air inside air conditioners, such as Midea's dual water washing technology (water washing filter) and Haier's centrifugal waterfall washing technology (water washing air). However, these technologies still involve the issue of adding water, and no effective solution has been provided for the discharge of polluting liquid after water washing, which limits the widespread application of these technologies. Furthermore, high-temperature sterilization alone can only treat the evaporator surface.

[0051] Specifically, the humidity control process primarily optimizes the ambient temperature and humidity to enhance the air conditioner's ability to accumulate pollutants in water vapor, while ensuring the necessary temperature and humidity conditions for condensation and frosting. Condensation generates condensate to clean the air conditioner's surface, simultaneously condensing water vapor from the pollutant-rich air onto the heat exchanger, or forming a filter medium with the heat exchanger to filter and collect airborne pollutants. Frosting removes and cleans pollutants from the heat exchanger, or forms a filter medium with the heat exchanger to filter and collect airborne pollutants. The drying process primarily aims to dry any remaining condensate and prevent odors and microbial growth in a humid environment. The high-temperature process utilizes heat for sterilization. By accumulating pollutants through water vapor and the air conditioner's heat exchanger, and discharging the condensate, the goal of purifying indoor air is achieved, while drying prevents any impact on the cleanliness of the internal components.

[0052] Because different programs have varying effects on different pollutants, the air conditioner determines its purification operation program based on the detected pollution level to achieve the best purification effect. The execution time of each program is related to factors such as current environmental parameters and the target pollution level (pollutant type and concentration). For the target pollutant, the program execution is as follows: (pretreatment, t1; condensation, t2; frosting, t3; defrosting, t4; drying, t5; high temperature, t6). Where t ≥ 0, when t = 0, it indicates that the purification of this target pollutant does not require running this program.

[0053] Based on the detected pollution levels, the purification operation procedure is determined to achieve the best purification effect. The types of indoor pollutants include indoor particulate pollutants, indoor microorganisms, and indoor gaseous pollutants. According to the type and concentration of the indoor pollutants, the treatment method of the purification function is determined, including at least one of the following: when the type of indoor pollutant is indoor particulate pollutant, the treatment method is the humidity treatment, the condensation treatment, and the drying treatment; when the type of indoor pollutant is indoor microorganism, the treatment method is the humidity treatment, the condensation treatment, the drying treatment, and the high-temperature treatment; when the type of indoor pollutant is indoor gaseous pollutant, the treatment method is the humidity treatment, the condensation treatment, and the drying treatment.

[0054] The types of pollutants inside the machine include particulate matter, microorganisms, and gaseous pollutants. Based on the type and concentration of the pollutants, the treatment method for the purification function is determined, including at least one of the following: when the pollutant is particulate matter, the treatment method is condensation treatment, frosting treatment, defrosting treatment, and drying treatment; when the pollutant is microorganisms, the treatment method is high-temperature treatment; when the pollutant is gaseous pollutants, the treatment method is condensation treatment and drying treatment.

[0055] Specifically, when it is necessary to purify both the air within the aforementioned preset space and the internal environment of the aforementioned electrical appliances simultaneously, there are many possible combinations of indoor and internal pollutants, all of which are included in the above examples and will not be listed individually here. The treatment methods for each pollutant are shown in Table 1.

[0056] Table 1. Treatment methods for each pollutant

[0057] Preprocessing Dew frost defrosting dry high temperature In-machine particulate matter ● ● ● ● Microorganisms inside the machine ● Odor inside the machine ● ● Indoor particulate matter ● ● ● Indoor microorganisms ● ● ● ● Indoor odor ● ● ●

[0058] Since the processing time of each treatment method is influenced by many factors, in order to achieve the best purification effect, the processing time of each treatment method needs to be controlled within an optimal range. Simultaneously, the purification process and time can be rationally optimized based on the type and concentration of the target pollutants, improving the purification effect while reducing the purification cycle, creating a more intelligent and healthy living environment for consumers. Based on the type and concentration of the indoor pollutants, and / or the type and concentration of the in-unit pollutants and the relevant parameters, the processing time of the aforementioned treatment methods is determined, including at least one of the following: constructing a first model, and determining the processing time of the humidity treatment based on the first model, the temperature of the preset space, the humidity of the preset space, the type and concentration of the indoor pollutants, wherein the first model is used to characterize the mapping relationship between the temperature of the preset space, the humidity of the preset space, the type and concentration of the indoor pollutants, and the processing time of the humidity treatment, wherein the temperature and humidity of the preset space are the relevant parameters; constructing a second model, and based on the second model, the type and concentration of the in-unit pollutants, the type and concentration of the indoor pollutants, and the operation of the air conditioning unit... The processing time for condensation is determined by considering the airflow rate and condensate film thickness. The second model characterizes the mapping relationship between the type of pollutants inside the unit, the concentration of pollutants inside the unit, the type of indoor pollutants, the concentration of indoor pollutants, the airflow rate of the indoor unit, the condensate film thickness, and the processing time for condensation. The airflow rate of the indoor unit and the condensate film thickness are the relevant parameters. A third model is constructed, and based on the third model, the type of pollutants inside the unit, the concentration of pollutants inside the unit, the type of indoor pollutants, the concentration of indoor pollutants, and the temperature inside the unit, the processing time for high temperature is determined. The third model characterizes the mapping relationship between the type of pollutants inside the unit, the concentration of pollutants inside the unit, the type of indoor pollutants, the concentration of indoor pollutants, the temperature inside the unit, and the processing time for high temperature. The temperature inside the unit is the relevant parameter.

[0059] Specifically, for the humidity control process, indoor environmental parameters, including temperature (T) and humidity (RH), are mainly regulated by the air conditioner itself. When the air conditioner's regulation cannot meet the humidity control requirements, an additional water tank or a fresh air humidification module is used for humidity control. The temperature and humidity are related to the type of pollutants and the currently detected concentration; preferably, 20 ≤ T ≤ 30℃ and 65% ≤ RH ≤ 75%. Furthermore, to better achieve the effects of this invention, the operating parameters of the humidification module are controlled so that the condensation diameter of water vapor in the air, d < 5 μm. The air conditioner is also controlled to maintain the current environmental parameters for a certain period of time, t1. The value of t1 is related to the current temperature, humidity, and the type and concentration of pollutants; preferably, 5 ≤ t1 ≤ 15 min. For the condensation process, the time t2 is related to the type and concentration of pollutants, the airflow rate W of the air conditioner, and the corresponding condensate film thickness δ. The condensate film thickness δ is adjusted and controlled by the temperature difference between the internal pipe temperature of the air conditioner and the saturation temperature in the corresponding environment, and is affected by the current environmental parameters. Preferably, δ < 0.15 mm and 5 ≤ t2 ≤ 15 min. For the frosting, defrosting, and drying processes, the above times are related not only to pollutants and environmental parameters but also to the running time of the previous stage of the process. For high-temperature processes, the above times are related to microbial concentration and temperature. Preferably, 56℃≤T, 30min≤t6.

[0060] The specific method for obtaining the humidity treatment time is as follows: taking particulate pollutants as an example, t1 = f1(C, H), specifically, t1 = f(C, H) = k1C / H, where k1 is a constant, C is the particulate matter concentration, and H is the absolute humidity, i.e., moisture content, which can be determined by indoor temperature and relative humidity.

[0061] The specific method for obtaining the treatment time of condensation treatment is as follows: taking particulate pollutants as an example, t2 = f2(C, δ, W), specifically, t2 = C / f2'(δ, W). Wherein, f2'(δ, W) represents the removal rate of pollutants under the hydrophilic film thickness and air volume, which is obtained through experimental methods.

[0062] The specific method for obtaining the high-temperature treatment time is: t6 = f6(M, T), specifically, t6 = M / [30 - k6(T - 56)]. Where k6 is a constant, M is the microbial concentration (content), and T is the temperature.

[0063] When there are multiple types of pollutants, the processing time of the corresponding treatment methods will be different. In order to completely purify all pollutants, the processing time of the treatment method is determined according to the type and concentration of the pollutants in the machine and / or the type and concentration of the indoor pollutants. The method further includes: when the pollutant in the machine is a first preset pollutant and the processing time of the preset treatment method for the first preset pollutant is a first preset time, and the indoor pollutant is a second preset pollutant and the processing time of the preset treatment method for the second preset pollutant is a second preset time, the actual processing time of the preset treatment method is the first preset time, wherein the first preset time is greater than or equal to the second preset time.

[0064] Furthermore, when multiple target pollutants are present, the air conditioner executes the purification process according to a program segment that includes all target pollutants, and the time taken for each program execution process is the maximum time taken for that process to purify each single target pollutant.

[0065] For example, when the following target pollutants are present alone, the air conditioner will purify them according to the following procedure:

[0066] Target pollutant a = (pretreatment, t1a; condensation, t2a; frosting, t3a; defrosting, t4a; drying, t5a; high temperature, t6a).

[0067] Target pollutant b = (pretreatment, t1b; condensation, t2b; frosting, t3b; defrosting, t4b; drying, t5b; high temperature, t6b).

[0068] Among them, t1a = 0, t6a = 0, t3b = 0, t4b = 0, t6b = 0, t2a > t2b, and t5a < t5b.

[0069] When two target pollutants are present simultaneously, the air conditioner purifies them according to the following procedure:

[0070] Target pollutants a, b = (pretreatment, t1b; condensation, t2a; frosting, t3a; defrosting, t4a; drying, t5b).

[0071] Correspondingly, the above method applies to any combination of pollutant types.

[0072] Specifically, the air conditioner controls the execution program and time determined based on the above-mentioned pollutant types and concentrations. Under certain temperature and humidity conditions, it adaptively adjusts the compressor frequency, four-way valve opening, indoor and outdoor fan speeds, and other actuators and parameters, so that the air conditioner runs according to the corresponding time under each program to complete the purification of pollutants inside the machine and indoors.

[0073] The air purification method described in this application first obtains the type and concentration of indoor pollutants, which are pollutants in the air within a preset space where the electrical appliance is located. Then, based on the type and / or concentration of the indoor pollutants, the method controls the electrical appliance to activate its purification function to purify the air within the preset space. This application eliminates the need for any additional purification devices; it utilizes the inherent advantages of the electrical appliance itself to achieve indoor air purification through water washing without requiring wastewater treatment or other operations. Furthermore, it eliminates the need for consumable replacements, saving manufacturing costs and solving the problem in existing technologies where electrical appliances alone cannot purify the indoor air environment.

[0074] According to embodiments of this application, such as Figure 4 As shown, an air purification device is provided. The device includes an acquisition unit 01 and a control unit 02.

[0080] In order to achieve indoor air purification by water washing using only the advantages of the appliance itself without the need for wastewater treatment or other operations, and without the need for consumable replacement, thus saving manufacturing costs, the appliance is an air conditioner. The air conditioner includes a heat exchanger. In the case of condensation, water droplets are attached to the surface of the heat exchanger. In the case of frost, frost crystals are attached to the surface of the heat exchanger.
