[0002] During air conditioning operation, condensed water is generated, collected in a drain pan and then drained outdoors through a drainpipe. Over time, the drain pan is exposed to a moist, warm environment ideal for the growth of bacteria and mold. This proliferation not only affects indoor air quality, but also causes these microorganisms to secrete a mucus in the air-conditioning environment. This mucus acts like an adhesive, bonding with dust, particles, and other materials to form a sticky deposit that clings to the drain pan surface, affecting the air conditioner's proper operation. This is known in the industry as bio-sludge.

[0052] In order to make the purpose, technical solutions and advantages of this application more clear, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0053] In the prior art, the methods for antibacterial treatment of air conditioner water trays are mainly divided into contact antibacterial methods and precipitation antibacterial methods. Among them, the contact antibacterial method has limited antibacterial effect, especially when the surface of the antibacterial water tray is covered with pollutants, it can no longer continue to work.

[0054] The precipitation-type antibacterial method is to set up an antibacterial module inside the water receiving tray. The antibacterial module precipitates antibacterial substances through the residual condensed water in the water receiving tray to exert its effect. However, in actual application, after the air conditioner's water receiving tray receives the condensed water, there will be a certain amount of residual condensed water for a long time. As a result, the precipitation speed of the antibacterial agent in the antibacterial module placed in the water receiving tray is uncontrollable, and the antibacterial effect is difficult to last.

[0055] Based on this, in one embodiment, the present application provides an air conditioner indoor unit, including: a shell, and an air inlet, an air outlet, an air duct, a water collection tray, an evaporator, an antibacterial module, an environmental parameter collection device and a controller encapsulated in the shell.

[0056] The air inlet and the air outlet are connected by an air duct, and a water receiving pan is arranged in the air duct to receive the condensed water flowing into the evaporator and discharge the condensed water from the indoor unit of the air conditioner.

[0057] Specifically, when the air conditioner is in cooling operation, the evaporator generates condensed water, which flows down the evaporator and gathers in the water receiving pan, and is discharged into the room through the air conditioner drain pipe connected to the water receiving pan.

[0058] The evaporator is arranged above the water receiving tray and is composed of fins and copper tubes that penetrate the fins through through holes on the surface of the fins.

[0059] Specifically, the evaporator may be a tube-fin evaporator, wherein the surface of the evaporator fins has a plurality of openings, and the copper tubes pass through the openings and penetrate the fins to form the evaporator.

[0060] The antibacterial module is arranged on the surface of the evaporator or in the through hole on the surface of the fin.

[0061] The antibacterial module is an item with antibacterial effect that uses porous media as a carrier to load and shape antibacterial active ingredients. The antibacterial active ingredients in the antibacterial module will dissolve and precipitate into the air conditioner water tray as they are flushed and dissolved by the condensed water flow at a certain temperature, thereby cleaning and purifying the water tray.

[0062] It is understandable that the porous medium in the antibacterial module may include a mixture of one or more of activated carbon, zeolite molecular sieves, silica gel, activated alumina, etc. The antibacterial active ingredient includes a mixture of one or more of inorganic, organic or natural antibacterial agent types. Among them, inorganic antibacterial agents are a type of antibacterial agent prepared by utilizing the bactericidal or antibacterial ability of metals such as silver, copper, zinc, titanium and their ions. Organic antibacterial agents include organic substances such as halides, organotin, isothiazoles, pyridine metal salts, imidazolones, aldehyde compounds, quaternary ammonium salts, etc. Natural antibacterial agents come from nature and include tea polyphenols, catechins, etc.

[0063] Specifically, placing the antimicrobial module on the evaporator surface or within the through-holes on the fins allows the module to fully utilize the evaporator's condensed water to precipitate the antimicrobial agent. This effectively avoids the traditional solution of placing the antimicrobial module inside the water tray, which results in uncontrollable precipitation speed and poor long-lasting antimicrobial effect. Furthermore, when the antimicrobial agent precipitates from the antimicrobial module on the evaporator surface or within the through-holes, its precipitation surface can cover the entire water tray area, effectively enhancing antimicrobial capacity and improving cleaning effectiveness.

[0064] In one embodiment, Figure 1 As shown, the antibacterial module is processed into a cylindrical structure with a circular cross-section and is arranged in a through hole on the surface of the evaporator fin.

[0065] Specifically, when preparing the evaporator fins, holes can be reserved in the fins as through-holes for installing the antimicrobial module. Later, when replacing the antimicrobial module, the same installation method for the copper tube on the fin can be used as a reference, allowing for easy assembly of the antimicrobial module without requiring structural adjustments to the air conditioner. It is understood that the diameter of the cylindrical antimicrobial module should be consistent with that of the copper tube.

[0066] In one embodiment, the antibacterial module can also be processed into any shape as long as it can be placed on the surface of the evaporator. Figure 2 As shown, the antibacterial module is processed into a rectangular strip and set on the surface of the evaporator, with the water receiving pan of the air conditioner below.

[0067] Among them, the environmental parameter collection device is used to collect the environmental parameters of the environment in which the air conditioner is located.

[0068] Specifically, the air conditioner indoor unit is also equipped with an environmental parameter collection device for detecting and collecting parameters such as indoor air quality and pollutant concentration. It is understood that the environmental parameter collection device can use any device capable of collecting parameters such as ambient air quality and pollutant concentration, such as a PM2.5 sensor or a microbial sensor.

[0069] The controller is connected to an environmental parameter acquisition device. Specifically, the controller obtains environmental parameters of the air conditioner's environment through the environmental parameter acquisition device; determines a required amount of antimicrobial agent when the water tray cleaning conditions are met based on the accumulated operating time of the air conditioner and the environmental parameters; determines cleaning parameters for the air conditioner based on the required amount of antimicrobial agent and a preset antimicrobial agent precipitation coefficient; and controls the air conditioner to operate in a cleaning mode based on the cleaning parameters.

[0070] The above-mentioned indoor unit of the air conditioner, by placing the antibacterial module in the through-hole on the surface of the evaporator or the surface of the fin, can make full use of the condensed water of the evaporator to precipitate the antibacterial agent. At the same time, it effectively avoids the problem in the traditional solution that the antibacterial module is placed inside the water receiving tray, which leads to uncontrollable precipitation speed of the antibacterial agent in the antibacterial module and difficulty in maintaining the antibacterial effect. Moreover, when the antibacterial agent of the antibacterial module on the surface of the evaporator or in the through-hole is precipitated, its precipitation surface can cover the entire water receiving tray area, effectively enhancing the antibacterial ability and improving the cleaning effect. The controller controls the air conditioner to run the cleaning mode according to the cleaning parameters, and can also make the antibacterial module precipitate the optimal concentration of antibacterial substances according to the actual situation of the air conditioner, realize the self-cleaning of the air conditioner docking water tray, and further effectively improve the cleaning effect of the air conditioner water receiving tray.

[0071] In one embodiment, the air conditioner indoor unit further includes an electric heating device connected to a controller for heating the antibacterial module. Specifically, the controller is connected to the electric heating device and controls the temperature of the antibacterial module by controlling the electric heating power of the electric heating device.

[0072] In one embodiment, Figure 3 As shown, an air conditioner cleaning control method is provided, which is described by taking the method applied to a controller in an air conditioner indoor unit as an example, and includes the following steps:

[0073] Step 302: Acquire environmental parameters of the environment where the air conditioner is located.

[0074] The environmental parameters of the air conditioner's environment are used to determine the concentration of pollutants in the air conditioner's environment. The environmental parameters can be used to determine the air quality and pollutant concentration of the air conditioner's environment. The worse the air quality, the higher the pollutant concentration, and the more likely the air conditioner's water pan will be contaminated by pollutant deposition. It is understood that the environmental parameters can be collected and detected in real time from the air conditioner's indoor environment, or they can be calculated as an average value obtained by periodically monitoring the indoor environment's environmental parameters.

[0075] Specifically, the controller is connected to an environmental parameter acquisition device of an indoor unit of the air conditioner to obtain environmental parameters of the environment in which the air conditioner is located, which are acquired by the environmental parameter acquisition device.

[0076] In one embodiment, the controller responds to a cleaning instruction sent by a user, obtains environmental parameters of the environment in which the air conditioner is located, and performs subsequent cleaning operations.

[0077] Step 304 : When it is determined that the water tray cleaning condition is met based on the accumulated operating time of the air conditioner and the environmental parameters, the required amount of antibacterial agent is determined.

[0078] The accumulated running time of the air conditioner refers to the running time of the air conditioner from the last time the cleaning mode was run to the current moment. It is understandable that after the air conditioner completes the cleaning mode, the accumulated running time will be reset to zero and the accumulated running time of the air conditioner will be recorded again.

[0079] The drain pan cleaning condition determines whether the drain pan needs to be cleaned. If the air conditioner's cumulative operating time and environmental parameters meet the drain pan cleaning condition, the drain pan is highly contaminated and the air conditioner needs to be switched to cleaning mode as soon as possible to ensure user health. If the air conditioner's cumulative operating time and environmental parameters do not meet the drain pan cleaning condition, the drain pan is not obviously contaminated and the contamination level is low, so switching to cleaning mode is not necessary.

[0080] In one embodiment, the water tray cleaning condition can be pre-set based on experimental or empirical values ​​of the air conditioner's cumulative operating time threshold and the environmental parameter threshold. When the air conditioner's cumulative operating time and environmental parameters both meet the water tray cleaning condition, the air conditioner is controlled to operate in the cleaning mode.

[0081] The required amount of antimicrobial agent is theoretically the amount of antimicrobial agent that the antimicrobial module needs to release to clean the air conditioner's water pan. The required amount of antimicrobial agent is related to the degree of contamination of the water pan; the greater the degree of contamination, the greater the amount of antimicrobial agent required. It is understood that the required amount of antimicrobial agent can refer to either the concentration or the mass of the antimicrobial agent.

[0082] Specifically, after obtaining the environmental parameters of the air conditioner's environment, the controller determines whether the air conditioner meets the water tray cleaning conditions based on the air conditioner's cumulative operating time and environmental parameters. If so, it determines the amount of antibacterial agent required when the air conditioner runs in cleaning mode.

[0083] Step 306 : Determine the cleaning parameters of the air conditioner based on the required amount of antimicrobial agent and the preset antimicrobial agent precipitation coefficient.

[0084] The preset antimicrobial agent precipitation coefficient characterizes the speed of antimicrobial agent precipitation, and the air conditioner's cleaning parameters influence the antimicrobial agent precipitation in the antimicrobial module. The controller determines the air conditioner's cleaning parameters based on the required amount of antimicrobial agent and the preset antimicrobial agent precipitation coefficient. Controlling the air conditioner to operate in a cleaning mode based on the cleaning parameters enables controlled antimicrobial agent precipitation in the antimicrobial module.

[0085] Specifically, the controller determines the cleaning parameters that affect the precipitation of the antimicrobial agent from the antimicrobial module based on the determined antimicrobial agent demand and a preset antimicrobial agent precipitation coefficient.

[0086] Step 308: Control the air conditioner to run a cleaning mode according to the cleaning parameters.

[0087] Specifically, the controller controls the air conditioner to run in a cleaning mode according to the cleaning parameters, thereby controlling the controlled precipitation of the antibacterial agent in the antibacterial module to clean the water receiving tray of the air conditioner.

[0088] In the above-mentioned air-conditioning cleaning control method, the environmental parameters of the environment in which the air conditioner is located are obtained. The environmental parameters can reflect the pollutant situation in the environment in which the air conditioner is currently located. When it is determined that the air conditioner meets the water tray cleaning conditions based on the accumulated operating time of the air conditioner and the environmental parameters, the required amount of antibacterial agent is determined, and the cleaning parameters of the air conditioner are determined based on the required amount of antibacterial agent and the preset antibacterial precipitation coefficient. Since the cleaning parameters are determined based on the required amount of antibacterial agent and the preset antibacterial precipitation coefficient, the cleaning mode of the air conditioner is controlled according to the cleaning parameters, which can enable the antibacterial module to precipitate the optimal concentration of antibacterial substances according to the actual situation of the air conditioner, thereby realizing self-cleaning of the air conditioner to the water tray, and effectively improving the cleaning effect of the air conditioner water tray.

[0089] In order to further accurately determine whether the air conditioner needs to run the cleaning mode, in one embodiment, Figure 4 As shown, when the water tray cleaning conditions are met based on the accumulated operating time of the air conditioner and environmental parameters, the required amount of antibacterial agent is determined, including:

[0090] Step 402: determining a water pan contamination value of the air conditioner based on the accumulated operating time of the air conditioner and environmental parameters.

[0091] The environmental parameter is the average indoor pollutant concentration over the cumulative operating time. Specifically, the controller obtains all parameters collected by the environmental parameter collection device over the cumulative operating time of the air conditioner and calculates the average pollutant concentration in the room where the air conditioner is located over the cumulative operating time by averaging.

[0092] Specifically, the controller determines the water pan contamination value P of the air conditioner according to the accumulated operating time t1 of the air conditioner and the average indoor pollutant concentration C during the corresponding time, that is, P=f1(t1, C).

[0093] In one embodiment, the controller determines the water pan contamination value of the air conditioner according to the accumulated operating time t1 of the air conditioner, the average indoor pollutant concentration C during the accumulated operating time, and the pollutant deposition coefficient k1.

[0094] The pollutant deposition coefficient k1 is a coefficient used to characterize the adhesion of pollutants in the current environment. The larger the pollutant deposition coefficient, the higher the probability of pollutants deposited in the air conditioner water tray causing pollution. Specifically, the water tray contamination value P = k1 × t1 × C.

[0095] Step 404 : Compare the water tray contamination value with a preset contamination threshold. If the water tray contamination value is greater than or equal to the preset contamination threshold, it is determined that the water tray cleaning condition is met.

[0096] The preset pollution threshold is a preset value used to characterize the pollution level of the air conditioner water pan, which is determined by the designer based on experimental tests or sampling of actual air conditioner usage and is pre-stored in the controller's database.

[0097] Specifically, the controller compares the water tray pollution value with the preset pollution threshold. If the water tray pollution value is greater than or equal to the preset pollution threshold, it means that the air conditioner has been running for a long time, and the indoor air quality is poor, the average pollutant concentration is high, and the degree of pollution of the water tray is high. It is necessary to run the relevant program as soon as possible for cleaning to ensure the health of the user. At this time, the controller determines that the air conditioner meets the water tray cleaning conditions.

[0098] Step 406 : Determine the required amount of antimicrobial agent corresponding to the water tray contamination value based on the water tray contamination value and a preset antimicrobial agent requirement table.

[0099] Among them, the preset antimicrobial agent demand table is used to store the correspondence between the water tray contamination value and the antimicrobial agent demand. It can be understood that the designer determines the antimicrobial agent demand corresponding to the water tray contamination value based on experimental tests or empirical values ​​during actual use of the air conditioner, and generates an antimicrobial agent demand table after binding the water tray contamination value and its corresponding antimicrobial agent demand. The antimicrobial agent demand table is pre-configured in the controller's database for easy access by the controller at any time.

[0100] Specifically, the controller searches a preset antimicrobial agent requirement table according to the calculated water tray contamination value, and determines the antimicrobial agent requirement corresponding to the water tray contamination value.

[0101] In this embodiment, the air conditioner's water pan contamination value is determined based on the unit's cumulative operating time and environmental parameters. This contamination value is then used to determine whether the water pan needs to be cleaned. This avoids frequent cleaning of the air conditioner, which could reduce the long-term effectiveness of the antimicrobial module. When cleaning is determined to be necessary, a pre-configured antimicrobial agent requirement table is queried based on the water pan contamination value to determine the antimicrobial agent requirement corresponding to the water pan contamination value. This provides a data basis for subsequently determining cleaning parameters based on the antimicrobial agent requirement.

[0102] In one embodiment, if the water tray contamination value is less than a preset contamination threshold, indicating that the air conditioner has been running for a short time or the air quality is good, the average pollutant concentration is not high, and the water tray is not obviously contaminated, cleaning is not necessary. The controller will generate a prompt message and send it to the user terminal or the air conditioner's built-in notification device, notifying the user that the water tray is relatively clean and no self-cleaning is required, thereby preventing the user from questioning the proper functioning of the air conditioner.

[0103] In one embodiment, determining the cleaning parameters of the air conditioner based on the required amount of antimicrobial agent and a preset antimicrobial agent precipitation coefficient includes:

[0104] The target cleaning value of the air conditioner is determined based on the required amount of the antimicrobial agent and the preset antimicrobial agent precipitation coefficient; and the cleaning parameters of the air conditioner are determined according to the target cleaning value.

[0105] Specifically, the controller determines the target cleaning value for the air conditioner based on the required amount of antimicrobial agent and a preset antimicrobial agent precipitation coefficient. Since an air conditioner generally has multiple cleaning parameters, the target cleaning value is determined as a baseline value. Multiple cleaning parameters can then be adjusted based on the baseline value to determine the optimal combination of the multiple cleaning parameters for the air conditioner, thereby obtaining the final cleaning parameters for the air conditioner. It is understood that the criteria for determining the optimal combination will vary depending on the actual situation, such as minimizing the duration of the cleaning mode or achieving more balanced parameter values ​​when the cleaning mode operates in synergy.

[0106] For example, the controller determines the antimicrobial agent requirement of the antimicrobial module when running in cleaning mode based on the water tray contamination value P. m is related to the air conditioner's cleaning parameters a, b, c and the preset antimicrobial agent precipitation coefficient k2, that is, m = k2 × a × b × c. Before determining the target a, b, and c parameters, the controller first calculates the target cleaning value m / k2, uses m / k2 as a reference value, and adjusts the cleaning parameters a, b, and c so that the air conditioner can achieve the optimal effect when running in cleaning mode according to the cleaning parameters. The cleaning parameters a, b, and c at this time are determined as the final cleaning parameters of the air conditioner. It can be understood that the number of cleaning parameters of the air conditioner depends on actual usage.

[0107] Furthermore, in one embodiment, the cleaning parameters include condensation water generation rate, antibacterial module temperature, and cleaning time. The cleaning parameters of the air conditioner are determined according to the target cleaning value, including:

[0108] The condensation water generation rate, antibacterial module temperature and cleaning time are determined according to the target cleaning value.

[0109] Among them, the condensation water generation rate is the rate at which condensation water is generated on the evaporator. Since the antibacterial agent in the antibacterial module needs to be flushed and dissolved by the condensation water flow before it can be precipitated and released into the water receiving tray, it plays the role of cleaning and purifying the water receiving tray. Therefore, when controlling the antibacterial agent in the antibacterial module to precipitate in a controllable manner according to the calculated antibacterial agent demand, the condensation water generation rate is an important influencing factor.

[0110] The antimicrobial module temperature is the operating temperature of the antimicrobial module when the controller is operating. As you can see, the antimicrobial module has a corresponding precipitation temperature. The antimicrobial agent in the antimicrobial module will only dissolve and precipitate under the influence of condensed water when the ambient temperature reaches the precipitation temperature. The corresponding precipitation temperature will also vary depending on the antimicrobial active ingredient loaded in the antimicrobial module. When the controller is controlling the antimicrobial module to precipitate the antimicrobial agent, it must heat the temperature of the antimicrobial module's environment (i.e., the module's operating temperature) to at least the corresponding precipitation temperature in order for the antimicrobial agent to precipitate.

[0111] Cleaning time refers to the running time of the air conditioner in cleaning mode. The longer the cleaning time, the longer the antibacterial module is flushed by condensed water at a certain working temperature, and the more antibacterial agent is precipitated. Therefore, cleaning time is also a factor affecting the precipitation of antibacterial agent by the antibacterial module.

[0112] Specifically, the controller uses the target cleaning value as the reference value, adjusts the specific parameter values ​​of the condensation water generation rate, antibacterial module temperature and cleaning time, and determines the parameter values ​​when the air conditioner operates in cleaning mode to achieve the optimal effect as the final condensation water generation rate, antibacterial module temperature and cleaning time.

[0113] For example, in actual applications, the precipitation of antimicrobial agents in the antimicrobial module is affected by the condensate generation rate and the temperature of the antimicrobial module. The faster the condensate generation rate and the higher the temperature of the antimicrobial module, the faster the antimicrobial agent precipitates from the antimicrobial module. However, if the antimicrobial module is continuously heated, while increasing the condensate generation rate, the operating efficiency and safety of the air conditioner will be affected. Therefore, when adjusting the condensate generation rate, the antimicrobial module temperature, and the cleaning time, the controller needs to find a balance point to ensure that the air conditioner's operating efficiency and safety are not affected while making the antimicrobial agent in the antimicrobial module precipitate faster. The condensate generation rate, antimicrobial module temperature, and cleaning time at this balance point are determined as the final condensate generation rate, antimicrobial module temperature, and cleaning time.

[0114] Controlling the air conditioner to operate in a cleaning mode according to the cleaning parameters includes: controlling the air conditioner to operate in a cleaning mode within the cleaning time according to the antibacterial module temperature and the condensed water generation rate.

[0115] Specifically, the controller controls the air conditioner to run in cleaning mode according to the temperature of the antibacterial module and the condensation water generation rate. When the running time of the cleaning mode reaches the cleaning time, it can be determined that the antibacterial module has precipitated an amount of antibacterial agent equal to the required amount of antibacterial agent, and the water collection tray of the air conditioner has been cleaned.

[0116] In one embodiment, the temperature of the antibacterial module is greater than the dew point temperature of the environment in which the air conditioner is located. The dew point temperature of the environment in which the air conditioner is located refers to the temperature at which condensation water is generated on the evaporator when the air conditioner is operating in cooling mode. The dew point temperature is related to the ambient temperature of the environment in which the air conditioner is located and can be a fixed value or a range of values.

[0117] Specifically, if the antimicrobial module temperature is lower than the dew point of the air conditioner's environment, then when the air conditioner is in cooling mode and condensation forms on the evaporator, the module will likely release a large amount of effective antimicrobial substances during normal cooling mode, as the current temperature meets the module's operating temperature and the condensation washes away. This can affect the module's long-term effectiveness. Therefore, setting the antimicrobial module temperature higher than the air conditioner's dew point can effectively prevent the module from releasing a large amount of effective antimicrobial substances during non-cleaning mode, leading to premature failure.

[0118] In the above embodiment, the condensation water generation rate and the antibacterial module temperature are determined according to the target cleaning value, the cleaning time of the air conditioner in the cleaning mode is determined based on the condensation water generation rate and the antibacterial module temperature, and the air conditioner is controlled to run in the cleaning mode according to the antibacterial module temperature and the condensation water generation rate until the running time reaches the cleaning time, ensuring that the antibacterial module washes out the antibacterial substance at the optimal concentration when running in the cleaning mode, realizing the self-cleaning of the water tray of the air conditioner, and effectively improving the cleaning effect of the water tray of the air conditioner.

[0119] During actual operation of the air conditioner, controlling the condensate production rate and the antibacterial module temperature requires adjusting system parameters in the air conditioner. In one embodiment, controlling the air conditioner to operate in a cleaning mode within the cleaning time period based on the antibacterial module temperature and the condensate production rate includes:

[0120] The compressor operating frequency, fan speed, electronic expansion valve opening and electric heating power of the air conditioner are determined based on the condensed water production rate and the antibacterial module temperature; according to the compressor operating frequency, fan speed, electronic expansion valve opening and electric heating power, the air conditioner is controlled to operate in cleaning mode within the cleaning time.

[0121] The condensation water generation rate v is achieved by controlling the system parameters of the air conditioner in combination with parameters such as ambient temperature and humidity. The system parameters include the compressor operating frequency, fan speed, and electronic expansion valve opening of the air conditioner.

[0122] The temperature T of the antibacterial module is achieved by the temperature control of the air conditioner itself and the electric heating device. Therefore, when the controller controls the temperature of the antibacterial module, it does so by controlling the electric heating power of the electric heating device.

[0123] Specifically, the controller determines the compressor operating frequency, fan speed, and electronic expansion valve opening of the air conditioner according to the condensed water production rate, and determines the electric heating power of the electric heating device in the air conditioner according to the temperature of the antibacterial module.

[0124] The controller operates in cleaning mode based on the determined compressor frequency, fan speed, and electronic expansion valve opening. It also periodically activates the electric heater based on the temperature of the antibacterial module to ensure the desired condensate generation rate and module temperature. When the operating time reaches the cleaning duration, a certain flow of condensate is generated and flushes the antibacterial module, releasing an amount of antimicrobial agent equal to the required amount into the water collection tray. This sterilizes microorganisms in the water collection tray or removes biosludge and other substances, achieving self-cleaning of the air conditioner's water collection tray and effectively improving its cleaning efficiency.

[0125] In order to further avoid the situation where the condensed water residue causes the water receiving tray to be contaminated, in one embodiment, Figure 5 As shown, an air conditioner cleaning control method is provided, comprising the following steps:

[0126] Step 502: Acquire environmental parameters of the environment where the air conditioner is located.

[0127] Step 504 : When it is determined that the water tray cleaning condition is met based on the accumulated operating time of the air conditioner and the environmental parameters, the required amount of antibacterial agent is determined.

[0128] Step 506 : Determine the cleaning parameters of the air conditioner based on the required amount of antimicrobial agent and the preset antimicrobial agent precipitation coefficient.

[0129] Step 508: Control the air conditioner to run a cleaning mode according to the cleaning parameters.

[0130] Specifically, the specific implementation of steps 502 to 508 is basically the same as the specific implementation of steps 302 to 308 above, and will not be repeated here.

[0131] Step 510: Control the air conditioner to operate in a non-condensing mode within a preset time period.

[0132] Specifically, after controlling the air conditioner to run in cleaning mode for a cleaning time period, the controller continues to control the air conditioner to run in non-condensing mode within a preset time period, such as air drying mode, to remove condensed water remaining on the water tray, thereby preventing some condensed water that does not contain antibacterial active ingredients or has insufficient active ingredients from remaining in the water tray, causing problems such as water tray contamination and microbial contamination to occur again.

[0133] In one embodiment, Figure 6 As shown, an air conditioner cleaning control method is provided, which specifically includes the following steps:

[0134] First, the air conditioner is powered on and receives a user-inputted command for a water tray self-cleaning operation. In response to this command, the controller obtains the average pollutant concentration in the air conditioner's environment over the air conditioner's cumulative operating time. The controller then calculates the water tray contamination value based on the accumulated operating time and the average pollutant concentration.

[0135] The water tray contamination value is compared with the preset contamination threshold to determine whether the air conditioner needs to be self-cleaned. If the water tray contamination value is less than the preset contamination threshold, the controller generates a prompt message and sends the prompt message to the user terminal or the air conditioner prompt device to remind the user that the water tray is relatively clean and does not need to be self-cleaned.

[0136] If the water tray contamination value is greater than or equal to the preset contamination threshold, it is determined that the air conditioner needs to be self-cleaned. The controller queries the preset antibacterial agent requirement table according to the water tray contamination value to determine the antibacterial agent requirement corresponding to the water tray contamination value.

[0137] According to the demand for antibacterial agent and the preset antibacterial agent precipitation coefficient, the condensate generation rate, antibacterial module temperature and cleaning time of the air conditioner are determined. Based on the condensate generation rate and antibacterial module temperature, the compressor operating frequency, fan speed, electronic expansion valve opening and electric heating power of the air conditioner are determined.

[0138] The controller runs the cleaning mode according to the determined compressor operating frequency, fan speed, and electronic expansion valve opening, and periodically turns on the electric heating device in combination with the antibacterial module temperature to ensure that the determined condensate generation rate and antibacterial module temperature are achieved.

[0139] After the air conditioner runs in the cleaning mode for a certain period of time, the controller continues to control the air conditioner to run in the non-condensing mode within a preset time period, such as the air supply drying mode, to remove the condensed water remaining on the water tray, so as to avoid some condensed water that does not contain antibacterial active ingredients or has insufficient active ingredients remaining in the water tray, causing problems such as water tray contamination and microbial contamination to occur again.

[0140] In this embodiment, when the air conditioner is turned on and running, it can judge the degree of dirtiness of the water tray according to user requirements or based on its own operating status, and at the same time determine and control the internal antibacterial module of the air conditioner to precipitate the optimal concentration of antibacterial substances under a specific temperature and an appropriate amount of condensed water, thereby achieving long-term self-cleaning of the water tray and ensuring the user's health.

[0141] It should be understood that, although the various steps in the flowcharts involved in the various embodiments described above are displayed in sequence according to the instructions of the arrows, these steps are not necessarily executed in sequence in the order indicated by the arrows. Unless otherwise specified herein, there is no strict order restriction on the execution of these steps, and these steps can be executed in other orders. Moreover, at least a portion of the steps in the flowcharts involved in the various embodiments described above can include multiple steps or multiple stages, and these steps or stages are not necessarily executed and completed at the same time, but can be executed at different times, and the execution order of these steps or stages is not necessarily to be carried out in sequence, but can be executed in turn or alternately with other steps or at least a portion of steps or stages in other steps.

[0142] Based on the same inventive concept, embodiments of the present application also provide an air conditioner cleaning control device for implementing the aforementioned air conditioner cleaning control method.

Since the cleaning parameters are determined based on the required amount of antibacterial agent and the preset antibacterial precipitation coefficient, the air conditioner operation cleaning mode is controlled according to the cleaning parameters, which can enable the antibacterial module to precipitate the optimal concentration of antibacterial substances according to the actual situation of the air conditioner, thereby realizing self-cleaning of the air conditioner to the water tray, and effectively improving the cleaning effect of the air conditioner water tray.
