[0052] In order to enable those skilled in the art to better understand the technical solution of the present disclosure, and to fully understand and implement how the present disclosure applies technical means to solve technical problems and achieve the corresponding technical effects, the technical solution in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only embodiments of a part of the present disclosure, not all of the embodiments. The embodiments of the present disclosure and the various features in the embodiments can be combined with each other without conflict, and the technical solutions formed are all within the scope of protection of the present disclosure. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without making creative work should fall within the scope of protection of the present disclosure.

[0053] It should be noted that the terms "first", "second", etc. in the specification and claims of the present disclosure and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present disclosure described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products, or devices.

[0054] It should be noted that the steps shown in the flowcharts of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and that, although a logical order is shown in the flowcharts, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0055] Condensed water is generated during the operation of the air conditioner, which is collected through the waterway (also called the waterway) and then discharged to the outside through the drain pipe. As the use time increases, the waterway is in a humid and warm environment suitable for the growth of bacteria and mold. The large-scale reproduction of bacteria and mold affects the quality of indoor air on the one hand, and on the other hand, the presence of these microorganisms will secrete a kind of mucus in the air-conditioning environment, which is like an adhesive, and adheres to dust, particles and other substances to form a sticky sediment that adheres to the surface of the waterway, affecting the normal use of the air conditioner. The industry calls it biological slime.

[0056] Microorganisms such as bacteria are the key to the above problems, so the existing technical means mainly control the waterway pollution problem by performing antibacterial treatment on the air conditioner waterway to inhibit the growth of microorganisms. However, the contact antibacterial method, such as antibacterial treatment of the surface material of the waterway, has limited effect, especially when the surface of the antibacterial waterway is covered by pollutants. The precipitation antibacterial method uses the condensed water remaining in the waterway to precipitate the antibacterial substance to exert its effect, but the speed is uncontrollable, the effect is difficult to last, and it will not work for a long time. Moreover, the chemical composition of the condensed water in the waterway is relatively complex, especially it is greatly affected by environmental pollution, and it is highly sensitive to changes in air pollution. Only a single method of antibacterial treatment cannot accurately sterilize, and the sterilization effect is poor.

[0057] The disclosed embodiment provides an air conditioner water channel purification device, which is applied to an air conditioner, wherein the air conditioner includes an indoor unit and an outdoor unit, wherein the indoor unit has an air inlet, an internal fan and an air outlet; the water channel is arranged in the air channel between the air inlet and the air outlet of the indoor unit of the air conditioner, and is used to gather the condensed water of the air conditioner; the purification device includes an electrolysis module; the electrolysis module is used to decompose the condensed water in the water channel to generate active bactericidal substances for purifying the water channel. The electrolysis module is controlled to electrolyze the condensed water to generate active bactericidal substances, thereby achieving long-term self-cleaning of the water channel. The active bactericidal substances generated by electrolysis include electrolyzed active oxygen and / or active chlorine, and can be electrolytically sterilized according to actual conditions to improve the sterilization effect, and the electrolysis module is efficient, durable and has no consumables, thereby ensuring the health of the user.

[0058] Among them, the type and output of active substances produced by electrolysis in the electrolysis module are usually related to the water quality of the condensed water. When the electrolyte is tap water, hundreds of substances are dissolved in it, including chloride ions, calcium ions, magnesium ions, potassium ions, dissolved oxygen, sulfates and other trace minerals. The presence of these substances causes tap water to mainly produce active chlorine, active oxygen and hydrogen during the electrolysis process. Active chlorine is Cl2, HClO and ClO － The sum of the three forms, HClO and ClO － The ratio is determined by the pH value of the electrolyte solution. Tap water contains a certain amount of chloride ions, which come from the dissolution of minerals on the one hand, and the other part comes from the chloride ions brought by chlorination disinfection. Reactive oxygen species (ROS) are a general term for substances in the body or natural environment that are composed of oxygen, contain oxygen and are active in nature, including ozone (O3), hydrogen peroxide (H2O2), hydroxyl (·OH), etc. The occurrence of electrolytic hydrogen production reaction in the electrolysis process of tap water is inevitable. At the same time, as the hydrogen ions (H + ) into hydrogen (H2), hydroxide ions (OH － ) increases. When calcium and magnesium ions are present in the water, scale will form on the cathode, reducing the efficiency of electrolysis. In particular, when the electrolyte is pure water, due to the lack of chloride ions, it is naturally impossible to produce bactericidal substances such as active chlorine. However, due to the lack of the influence of chlorine ions, the production of certain active substances will be greatly improved. In theory, air conditioning condensate is highly pure water, which is directly condensed from water vapor in the air and can be considered as pure water. In fact, in the process of water vapor condensation, it will absorb impurities such as suspended dust, smoke, microorganisms and chemical emissions in the air. Therefore, condensate is not pure water, and its chemical composition is relatively complex. It is especially affected by environmental pollution and is highly sensitive to changes in air pollution.

[0059] In addition, differences in electrode materials (same as catalysts) and electrolysis conditions will also lead to different electrolysis products and production amounts. The influence of electrode materials mainly comes from the selective catalytic properties of catalysts. For example, ethanol can be dehydrogenated to acetaldehyde at high temperatures, and can also be dehydrated to ethylene. Silver catalysts can promote the former reaction, while aluminum oxide catalysts promote the latter reaction. The water electrolysis process is also a multi-reaction system. Different catalysts have different effects on different reactions, resulting in different final products and contents. The same is true for electrolysis conditions. Active substances such as H2O2 can use low voltage, but high-voltage electrolysis such as OH is more effective.

[0060] In short, the sterilization effect of the electrolysis module is related to the type and content of the active substance, and is affected by factors such as water quality components, electrode materials, and electrolysis conditions.

[0061] In this embodiment, according to the water quality characteristics of air-conditioning condensate water, the electrolytically active bactericidal substances generated by electrolysis in the electrolysis module include electrolytically active oxygen and electrolytically active chlorine, thereby enabling targeted purification and improving the purification effect.

[0062] Embodiment 1

[0063] Figure 1 This is a schematic diagram of the structure of an air conditioning water purification device provided by an embodiment of the present disclosure. Figure 1 As shown, an air-conditioning water channel purification device includes an electrolysis module; the electrolysis module is used to decompose condensed water in the water channel to generate active bactericidal substances for purifying the water channel, wherein the active bactericidal substances include electrolytic active oxygen and / or electrolytic active chlorine.

[0064] In this embodiment, the air conditioner includes an indoor unit and an outdoor unit, the outdoor unit includes a compressor, an external fan, a condenser and other components, and the indoor unit includes an air inlet, an internal fan and an air outlet; the air inlet and the air outlet are connected to form an air duct, and the internal fan is installed in the air duct; wherein, the air conditioning water channel (i.e., a water receiving pan) is installed in the air duct connected to the air inlet and the air outlet, and is used to collect the condensed water generated by the air conditioner. An evaporator is installed above the water channel. When the air conditioner is in cooling operation, the evaporator will generate condensed water, which will flow down along the evaporator fins and gather in the water channel, flow from the high position of the water channel to the low position, and finally be discharged to the outside through the drain nozzle and the air conditioner drain pipe. Optionally, the drain nozzle has a controllable opening and closing valve, and the condensed water can be controlled to stay in the water channel by opening and closing the valve.

[0065] Further, such as Figure 2 As shown, the electrolysis module includes a first electrode group for generating electrolytic active oxygen and a second electrode group for generating electrolytic active chlorine; wherein the first electrode group and the second electrode group both include a cathode electrode and an anode electrode; when the electrolysis module is required to generate electrolytic active oxygen, the first electrode group is controlled to be powered on for electrolysis to generate electrolytic active oxygen; when the electrolysis module is required to generate electrolytic active chlorine, the second electrode group is controlled to be powered on for electrolysis to generate electrolytic active chlorine. By providing two groups of electrode groups, electrolysis can be carried out in a targeted manner according to the water quality of the condensed water, so as to improve the purification and sterilization effect of the active bactericidal substances generated by electrolysis.

[0066] In this embodiment, the electrolysis module can be connected to a suitable discharge voltage so that the electrode group electrolyzes the condensed water to generate active bactericidal substances for sterilization. Among them, the first and second electrode groups include precious metal electrodes such as titanium electrodes (Ti) and platinum electrodes (Pt) with high catalytic activity. When they are powered on and electrolyzed at a certain voltage, they can produce active bactericidal substances such as hydroxyl free radicals and hypochlorous acid with strong oxidizing properties, which can effectively kill bacteria and other microorganisms.

[0067] Furthermore, the purification device also includes a detection unit and a control unit; wherein the detection unit is used to monitor the water quality of the condensed water; the control unit is connected to the detection unit and the electrolysis module, and is used to determine the electrolysis operation mode of the electrode module according to the water quality of the condensed water detected by the detection unit, and control the electrolysis module to operate according to the electrolysis operation mode. The electrolysis operation mode includes the electrolysis to generate the corresponding active bactericidal substances and the working parameters of the electrolysis process. Different electrolysis operation modes can provide different active bactericidal substances, so as to perform targeted sterilization and purification according to the water quality of the condensed water and improve the purification effect.

[0068] Among them, the detection unit includes a pH sensor, a conductivity sensor, a characteristic ion concentration sensor, etc., so as to detect the water quality of the condensed water and provide favorable conditions for determining the electrolysis mode.

[0069] In some embodiments, Figure 1 and Figure 3 As shown, the purification device also includes an air quality detection unit for detecting indoor air quality and an air temperature and humidity detection unit for detecting indoor ambient temperature and humidity, so that the operation mode of the air conditioner can be controlled according to the detected air quality and air temperature and humidity. When the air quality is poor, the control unit determines that purification is needed, and the purification device can be enabled to perform self-cleaning treatment on the air conditioner, so that the electrolysis mode is determined according to the water quality of the condensed water detected by the water quality detection unit, and then the electrolysis is carried out in a targeted manner to improve the electrolysis efficiency and electrolysis effect. When the air temperature and humidity do not meet the user's requirements, the operating temperature and dehumidification parameters of the air conditioner are adjusted to adjust the air temperature and humidity to meet the user's set requirements.

[0070] In some embodiments, the number of electrolysis modules can be determined according to the structure of the waterway to ensure that the electrolytic active substances can flow through all waterway areas. For example, three electrolysis modules are respectively arranged at the high position, middle position and low position of the waterway to ensure that the electrolytic active substances can flow through all waterway areas.

[0071] The installation position of the electrolysis module can be set according to actual needs. For example, the electrolysis module can be set at a high position in the waterway, which can reduce the number of electrolysis modules and control costs. At the same time, the electrolytic active substances can flow through the entire waterway with the condensed water to ensure the purification and sterilization effect of the entire area. When the above-mentioned drain nozzle is equipped with a controllable drain valve, the condensed water can be kept in the waterway for a long time because the drain valve is closed. The electrolysis module can be well set at any position in the waterway to achieve electrolysis and ensure the purification effect.

[0072] The purification device provided by the embodiment of the present disclosure electrolyzes condensed water through an electrolysis module to generate active bactericidal substances, thereby achieving long-term self-cleaning of the waterway. The active bactericidal substances generated by electrolysis include electrolyzed active oxygen and / or active chlorine, and can be electrolytically sterilized according to actual conditions to improve the sterilization effect. It is efficient, durable and has no consumables, ensuring the health of users. The water quality of the condensed water is monitored by a detection unit, and the corresponding electrolysis operation mode is determined according to the monitored water quality, so that the electrolysis module can generate active bactericidal substances corresponding to the water quality conditions, accurately analyze the water quality of the condensed water in the waterway, and then provide a targeted electrolysis operation mode, accurately perform electrolytic sterilization, and improve the sterilization efficiency and sterilization effect.

[0073] Embodiment 2

[0074] Based on the above embodiment, the difference between this embodiment and embodiment 1 is that Figure 4 As shown, the electrolysis module includes a cathode electrode, a first anode electrode and a second anode electrode; the first anode electrode and the second anode electrode can be connected to the cathode electrode respectively, wherein when the first anode electrode is connected to the cathode electrode, electrolytic active oxygen is generated; when the second anode electrode is connected to the cathode electrode, electrolytic active chlorine is generated. By sharing a cathode electrode, the size of the electrolysis module body can be reduced, and the first anode electrode and the second anode electrode are alternately operated. Only one electrolytic active substance can be generated by a single power-on. Different electrolytic active substances can be generated by alternately switching the connection of the anode electrodes, ensuring that after one of the electrolytic active substances is sterilized, the other electrolytic active substance can be converted for sterilization, avoiding interference caused by the simultaneous existence of two electrolytic active substances, and improving the sterilization effect.

[0075] Embodiment 3

[0076] Based on the above embodiment, the difference between this embodiment and embodiment 1 is that Figure 5 As shown, the electrode group includes a first electrode and a second electrode; the first electrode and the second electrode can adjust the polarity of their electrodes according to the direction of current, so that they can be used as anodes or cathodes according to the direction of current; when the first electrode is an anode, the second electrode is a cathode, and the two cooperate to generate electrolytic active chlorine by electrolysis; when the first electrode is a cathode, the second electrode is an anode, and the two cooperate to generate electrolytic active oxygen by electrolysis.

[0077] Specifically, when the current is positive, the first electrode is an anode and the second electrode is a cathode, and the two cooperate to generate electrolytic active chlorine by electrolysis; when the current is negative, the first electrode is a cathode and the second electrode is an anode, and the two cooperate to generate electrolytic active oxygen by electrolysis.

[0078] By controlling the switching of the current direction, the electrolysis working mode of the electrode group can be switched, the number of electrodes can be reduced, and the response speed is fast, thereby improving the electrolysis sterilization effect.

[0079] Embodiment 4

[0080] On the basis of the above embodiments, this embodiment provides an air conditioning water channel self-cleaning control method, which is implemented based on the water purification device described in the above aspects, such as Figure 6 As shown, the control method includes: in response to a request for executing waterway cleaning, detecting the quality of condensed water in the air-conditioning waterway; determining the electrolysis operation mode of the electrolysis module based on the quality of the condensed water; and controlling the electrolysis module to operate according to the electrolysis operation mode, thereby decomposing the condensed water in the waterway to generate active bactericidal substances for purifying the waterway. By electrolyzing the condensed water in the waterway, corresponding active bactericidal substances can be generated according to the quality of the condensed water in the waterway, thereby improving the sterilization effect, and being efficient, durable, and free of consumables, ensuring the health of users.

[0081] Specifically, the control method includes steps S1-S3, and the specific contents are as follows:

[0082] S1. In response to a water channel cleaning execution request, detecting the water quality of condensed water in the air conditioning water channel;

[0083] S2. determining an electrolysis operation mode of an electrolysis module based on the water quality of the condensed water;

[0084] S3. Control the electrolysis module to operate in the electrolysis operation mode, thereby decomposing the condensed water in the water channel to generate active bactericidal substances for purifying the water channel.

[0085] In some embodiments, Figure 7 As shown, the execution request in response to waterway cleaning in step S1 includes:

[0086] S11, responding to a waterway self-cleaning instruction input by a user;

[0087] S12, obtaining current air conditioning operation data based on the water channel self-cleaning instruction;

[0088] S13, analyzing the pollution degree of the waterway according to the operation data of the air conditioner, and determining whether the current pollution degree of the waterway requires running a self-cleaning program;

[0089] If so, determining to respond to the request for execution of the waterway cleaning;

[0090] If not, a prompt message is sent to the user to remind the user that the water channel does not need to be electrosterilized.

[0091] Among them, the water channel self-cleaning instruction is an instruction to control and monitor the pollution level of the above water channel and determine whether electrolytic sterilization is required. The pollution level of the water channel is represented by a numerical value. It is determined whether the current pollution level of the water channel needs to run the self-cleaning program. The pollution level of the water channel is compared with the preset water channel pollution level threshold. If it exceeds the pollution level threshold, it is determined that cleaning is required and the execution request of water channel cleaning is responded; if it does not exceed the pollution level threshold, it is determined that cleaning is not required and the user is prompted. The prompting method can use voice push, panel display and mobile phone push to remind the user that the water receiving container is currently clean and does not need electrolytic sterilization, so as to avoid users questioning the normal operation of the air conditioner function.

[0092] In other embodiments, Figure 8 As shown, the operation request for waterway cleaning in step S1 includes:

[0093] S111, regularly obtaining real-time operation data of the air conditioner according to a preset periodic interval;

[0094] S112, determining the pollution degree of the waterway according to the real-time operation data of the air conditioner, and judging whether the current pollution degree of the waterway requires running a self-cleaning program;

[0095] If so, an operation request for waterway cleaning is automatically generated and executed in response;

[0096] If not, then end.

[0097] By regularly and automatically monitoring the pollution situation of the air conditioner, it can automatically and regularly clean the air conditioner according to the pollution situation, making it convenient for the air conditioner to achieve automatic cleaning and ensuring the user experience and health of the user.

[0098] Furthermore, in order to facilitate the calculation of the pollution degree of the waterway, the pollution degree of the waterway is recorded as P. The pollution degree of the waterway P is determined by combining the cumulative operation time T1 of the air conditioner and the average indoor pollutant concentration C during the corresponding time, that is, P = f(T, C). In particular, P = k1×T1×C. k1 is the pollutant deposition coefficient, which represents the degree of pollution of the waterway caused by the deposition and growth of pollutants.

[0099] The accumulated operation time T1 can be determined by the operation time of the air conditioner motor, and the indoor average pollutant concentration C is obtained by real-time or periodic detection by the indoor pollutant sensor and calculation of the corresponding average value.

[0100] By collecting the actual water pollution data of air conditioners in different environments and combining it with expert experience and consumers' demand for water cleanliness, we can determine the acceptable threshold value P0. By comparing the relationship between the water pollution level P and the threshold value P0, we can determine the severity of the pollution. Specifically:

[0101] When the water channel pollution degree P < the preset value P0, it is judged as no, which means that the cumulative running time of the air conditioner is not long or the air quality is good, and the water channel is not obviously dirty, and no relevant cleaning is required; in particular, when it is judged that the water channel does not need self-cleaning, but the water channel self-cleaning instruction comes from the user, it is necessary to use voice push, panel display and mobile phone push to remind the user that the water channel is currently clean and does not need self-cleaning, so as to avoid users questioning the normal operation of the air conditioner function.

[0102] When the water channel pollution degree P ≥ preset value P0, it is judged as yes, which means that the air conditioner has been running for a long time or the indoor air quality is poor, and the water channel is likely to be dirty. It is necessary to run the water channel self-cleaning program as soon as possible to ensure the health of users.

[0103] Optionally, the degree of pollution of the waterway may also be directly determined by the accumulated operating time or the interval time from the last self-cleaning, or an intuitive judgment through visualization technology such as a camera may also achieve the effect of the present invention.

[0104] In some embodiments, after responding to the request for executing waterway cleaning, before the step of detecting the water quality of the condensed water in the air conditioning waterway, as Fig. 9 As shown, the control method also includes:

[0105] S101, obtaining the pollution degree in the waterway and the maximum amount of condensed water allowed to be stored in the waterway;

[0106] S102, determining the condensation time for the air conditioner to condense the airflow in the water channel according to the pollution degree of the water channel and the maximum amount of condensed water allowed to be stored in the water channel;

[0107] S103, controlling the air conditioner to perform condensation operation on the water channel until the condensation operation duration reaches the condensation duration.

[0108] When it is determined to execute the cleaning request, the air conditioner is controlled through the above steps to condense the water channel so that the condensed water in the rice reaches the required amount, thereby facilitating the subsequent electrolysis module to electrolyze and generate active bactericidal substances to achieve self-cleaning.

[0109] Among them, in step S102, the condensation time is related to the degree of water channel pollution, that is, t1=f1(P). At the same time, in order to avoid overflow of condensed water due to excess capacity, the condensation time is also affected by the water channel structure of the air conditioner (limiting the maximum condensation amount to prevent overflow) and the ambient temperature and humidity (the moisture content in the air, limiting the maximum possible condensation amount). Under normal circumstances, the amount of condensed water that can be condensed in the air-conditioning water channel is determined by analyzing the moisture content in the air, and then the condensation time is set in combination with the maximum condensed water amount and the degree of water channel pollution to ensure that the amount of active bactericidal substances generated by the electrolysis of the condensed condensed water can meet the previous water channel pollution degree and does not exceed the maximum capacity limit.

[0110] Furthermore, the process of controlling the air conditioner to perform condensation operation on the water channel until the condensation operation duration reaches the condensation duration specifically includes:

[0111] Control the drain valve of the air-conditioning water channel to close, and make the internal fan of the air-conditioning indoor unit run at the first windshield v1, and the air-conditioning outdoor unit run at the first frequency p1, until the running time under the first preset condition reaches the condensation time t1, so that condensation is generated between the fins and gathered in the water channel; the first frequency corresponds to the ambient temperature, and the first preset condition is that the tube temperature of the evaporator is less than or equal to the first temperature, and the first temperature corresponds to the dew point temperature corresponding to the air; the ambient temperature and dew point temperature are detected and obtained by the ambient temperature and humidity sensor, and the first frequency is determined accordingly; by first condensing the condensation in the water channel, condensed water can be generated, so that it is convenient to obtain the water quality conditions corresponding to the condensed water according to the condensed water, so as to facilitate the targeted selection of the electrolysis mode for electrolysis treatment.

[0112] In some embodiments, Fig.10 As shown, the step of detecting the water quality of condensed water in the air conditioning water channel includes:

[0113] S104, obtaining condensate water quality test data;

[0114] S105, determining a water quality index for characterizing the water quality conditions of the condensed water according to the condensed water quality detection data;

[0115] S106. Comprehensively evaluate the water quality indicators to obtain water quality condition parameters for representing the water quality of the condensed water in the current waterway.

[0116] The water quality condition is characterized by conventional water quality indicators, including one or more of the indicators such as pH value, electrical conductivity EC, hardness, turbidity, permanganate index, etc. Optionally, the water quality condition can also be directly characterized by the content of ions strongly related to electrolysis, such as one or more of chloride ions, calcium and magnesium ions, ammonium ions, etc., which is specifically determined by the characteristics of the electrolysis module.

[0117] When multiple water quality indicators are used to judge water quality parameters, it is necessary to conduct a comprehensive evaluation of electrolysis water quality. Here, Y is defined as the comprehensive judgment parameter of electrolysis water quality conditions, y1, y2, ..., y j For different water quality indicators, b1, b2, ..., b j is the influence coefficient of different water quality indicators on electrolysis water quality conditions, then Y=y1·b1+y2·b2+……+y j b j In particular, the influence coefficient b of different water quality indicators on electrolysis water quality conditions is defined here j Can be positive or negative. j When it is positive, it means that the water quality index is helpful to improve the electrolysis effect, and vice versa. The larger the Y value, the better the electrolysis water quality conditions.

[0118] In some embodiments, the electrolysis operation mode in step S2 includes a first electrolysis mode for generating electrolytic active oxygen and a second electrolysis mode for generating electrolytic active chlorine, as well as operating parameters of the first electrolysis mode and the second electrolysis mode.

[0119] Based on this, the step S2, such as Fig.11 As shown, specifically including:

[0120] S21, determining whether the water quality condition parameter of the condensed water exceeds a preset threshold value of the condensed water quality pollution condition;

[0121] If so, the electrolysis operation mode of the electrolysis module is determined with the goal of generating active chlorine by electrolysis;

[0122] If not, the electrolysis operation mode of the electrolysis module is determined with the goal of generating active oxygen by electrolysis.

[0123] Among them, the threshold value of the condensate water pollution condition is recorded as Y0; the water quality condition parameter is recorded as Y, as stated above:

[0124] When Y≤Y0, it means that the existing water quality conditions are conducive to the generation of active oxygen, and the electrolysis module mainly operates in the electrolysis active oxygen mode; when Y>Y0, it means that the existing water quality conditions are conducive to the generation of active chlorine, and the electrolysis module mainly operates in the electrolysis active chlorine mode.

[0125] Furthermore, step S2 also includes:

[0126] S22. Determine the operating parameters of the electrolysis module according to the content of the condensed water and the water quality of the condensed water, wherein the operating parameters include an operating voltage and / or an operating duration.

[0127] Specifically, the working voltage is recorded as V1 and the working time is recorded as t2, and the two are inversely correlated (that is, the time decreases when the voltage increases, and vice versa), and are related to the water quality condition Y and the condensed water content (the same as the first preset time), that is, V1×t2=f2(Y, t1). In the specific control process, voltage control can be mainly used, and time adjustment can be auxiliary, that is, the voltage and time range are determined according to the water quality conditions and the condensed water content, and the time is determined by controlling the voltage. Among them, it is easy for people in this field to understand that the better the water quality conditions (parameter Y), the more condensed water content (parameter t1), theoretically, the more active substances produced by electrolysis, and the better the effect, at this time The voltage (parameter V1) and time (parameter t2) can be reduced accordingly.

[0128] In some embodiments, in step S3, the electrolysis module is controlled to operate in the electrolysis operation mode, so as to decompose the condensed water in the water channel to generate active bactericidal substances for purifying the water channel.

[0129] Among them, after controlling the electrolysis module to work according to the electrolysis operation mode, that is, when the corresponding active bactericidal substances are generated by electrolysis and the electrolysis time reaches the working time, the electrolysis module is turned off to allow the electrolyzed water to stand for a period of time, so that the active bactericidal substances generated by electrolysis in the condensed water can fully react with harmful microorganisms in the waterway to achieve the best purification effect, wherein the standing time of the electrolyzed water is related to the content of electrolytic active substances (that is, the electrolysis working time), that is, t3=f3(t2).

[0130] In some embodiments, after determining the electrolysis operation mode of the electrolysis module and controlling the electrolysis module to operate and clean in the electrolysis operation mode, the control method will periodically detect the air conditioning pollution level and automatically restart steps S1-S3 based on this. Therefore, when the water quality condition parameter of the condensed water exceeds the preset threshold value of the condensed water quality pollution condition, the electrolysis operation mode of the electrolysis module is determined with the goal of electrolyzing to generate active chlorine, and after the electrolysis cleaning is completed with the goal of electrolyzing to generate active chlorine, the air conditioning pollution level is periodically detected, and steps S1-S3 are automatically restarted based on this. At this time, the water quality condition parameter of the condensed water may not exceed the threshold value of the condensed water quality pollution condition, so that the electrolysis operation mode with the goal of electrolyzing to generate active oxygen can be combined for electrolysis cleaning, and the pollution in the waterway can be further cleaned to give full play to the purification effect and improve the purification effect.

[0131] In some embodiments, step S3, such as Fig.12 As shown, including:

[0132] S31, controlling the electrolysis module to operate according to the electrolysis operation mode until the operation time of the electrolysis module reaches the operation time;

[0133] S32, controlling the electrolysis module to shut down and start timing until the timing reaches a first preset time, so that the active bactericidal substances generated by electrolysis sterilize harmful microorganisms in the water receiving container;

[0134] S33, controlling the drain valve of the water channel to open, so as to discharge the condensed water in the water receiving container through the drain port;

[0135] S34, controlling the air conditioner to start a heating mode until a drying time reaches a second preset time, where the drying time is the time for drying the condensed water remaining in the water receiving container.

[0136] By discharging the condensed water and controlling the air conditioner to perform drying operations, it is possible to prevent condensed water from remaining in the waterway and causing problems such as waterway dirt and microbial contamination to occur again.

[0137] The control method provided by the embodiment of the present disclosure can automatically detect the degree of waterway contamination according to user instructions or the air conditioner. When the degree of waterway contamination exceeds the necessary limit, the air conditioner is controlled to operate at a certain wind speed, frequency, etc. based on the degree of contamination to produce a certain amount of condensed water, and at the same time detect its electrolysis water quality conditions, and then control the electrolysis module to determine the best electrolysis operation mode in combination with the water quality conditions to produce enough of the most efficient active bactericidal substances, and maintain for a certain period of time so that harmful microorganisms are fully purified, and then control the air conditioner to operate the heating mode at a certain wind speed, frequency, etc. to dry the moisture in the waterway and other areas inside the air conditioner to complete the waterway self-cleaning process. Furthermore, when it is determined that the waterway does not need to be self-cleaned or the waterway self-cleaning program is completed, the air conditioner is controlled to operate the cooling and heating modes normally according to the user's needs, and the degree of waterway contamination is detected in real time or at a fixed time, and then the waterway self-cleaning mode is executed again as needed.

[0138] Embodiment 5

[0139] Based on the above embodiments, this embodiment provides a specific application embodiment of an air conditioning water channel self-cleaning control method.

[0140] like Fig.13 As shown, the control method includes the following process:

[0141] 1. Turn on the air conditioner and run it.

[0142] 2. Obtain the user's water tray self-cleaning instruction.

[0143] 3. Detect the degree of contamination of the air conditioner water tray and determine whether the self-cleaning program needs to be run.

[0144] The water tray contamination degree P is determined by combining the accumulated operation time T1 of the air conditioner and the average indoor pollutant concentration C during the corresponding time, that is, P = f(T, C). In particular, P = k1×T1×C. k1 is the pollutant deposition coefficient, which represents the degree of contamination of the water tray caused by the deposition and growth of pollutants.

[0145] The accumulated operation time T1 can be determined by the operation time of the air conditioner motor, and the indoor average pollutant concentration C is obtained by real-time or periodic detection by the indoor pollutant sensor and calculation of the corresponding average value.

[0146] By collecting the actual pollution data of the water tray of the air conditioner in different environments and combining it with the expert experience and the consumer's demand for the cleanliness of the water tray, the acceptable threshold value P0 can be determined. By comparing the relationship between the pollution level P of the water tray and the threshold value P0, the severity of the pollution can be judged. Specifically:

[0147] When the water tray contamination degree P < the preset value P0, it is judged as no, which means that the cumulative running time of the air conditioner is not long or the air quality is good, and the water tray is not obviously dirty, and no relevant cleaning is required; in particular, when it is judged that the water tray does not need to be self-cleaned, but the water tray self-cleaning instruction comes from the user, voice push, panel display and mobile phone push are required to remind the user that the water tray is currently clean and does not need to be self-cleaned, so as to avoid users questioning the normal operation of the air conditioner function.

[0148] When the water tray contamination level P ≥ preset value P0, it is judged as yes, which means that the air conditioner has been running for a long time or the indoor air quality is poor, and the water tray is likely to be dirty. It is necessary to run the water channel self-cleaning program as soon as possible to ensure the health of the user.

[0149] Optionally, the degree of contamination of the water receiving tray can also be directly determined by the accumulated operating time or the interval time from the last self-cleaning, or intuitively determined by visualization technology such as a camera to achieve the effect of the present invention.

[0150] 4. Control the air conditioner to perform self-cleaning of the water tray.

[0151] The water tray self-cleaning process includes condensation, electrolytic sterilization and drying. The process is carried out in sequence, specifically:

[0152] 1) Condensation process

[0153] The drain nozzle valve of the air conditioner water receiving pan is controlled to be closed, the internal fan is operated at the first wind speed v1, and the compressor is operated at the first frequency p1, until the operating time under the first preset condition reaches the first preset time t1, so that condensation is generated between the fins and gathers in the water receiving pan; the first frequency corresponds to the ambient temperature, and the first preset condition is that the tube temperature of the evaporator is less than or equal to the first temperature, and the first temperature corresponds to the dew point temperature of the air; the ambient temperature and the dew point temperature are detected and obtained by the ambient temperature and humidity sensor, and the first frequency is determined accordingly; the first preset time is related to the degree of contamination of the water receiving pan, that is, t1=f1(P), and is affected by the structure of the air conditioner water receiving pan (limiting the maximum condensation amount to prevent overflow) and the ambient temperature and humidity (the amount of moisture in the air, limiting the maximum possible condensation amount).

[0154] 2) Electrolytic sterilization process

[0155] A\Control the water quality detection unit to obtain the condensate water quality conditions (parameters).

[0156] The water quality condition is characterized by conventional water quality indicators, including one or more of the indicators such as pH value, electrical conductivity EC, hardness, turbidity, permanganate index, etc. Optionally, the water quality condition can also be directly characterized by the content of ions strongly related to electrolysis, such as one or more of chloride ions, calcium and magnesium ions, ammonium ions, etc., which is specifically determined by the characteristics of the electrolysis module.

[0157] Furthermore, when multiple water quality indicators are used to judge water quality conditions, a comprehensive evaluation of electrolysis water quality is required. Here, Y is defined as the comprehensive judgment parameter of electrolysis water quality conditions, y1, y2, ..., yj are different water quality indicators, b1, b2, ..., bj are the influence coefficients of different water quality indicators on electrolysis water quality conditions, then Y = y1·b1+y2·b2+...+yj·bj. In particular, the influence coefficient bj of different water quality indicators on electrolysis water quality conditions defined here can be positive or negative values. When bj is positive, it means that the water quality indicator helps to improve the electrolysis effect, and vice versa. In this way, the larger the Y value, the better the electrolysis water quality conditions.

[0158] B\Determine the electrolysis operation mode and parameters based on water quality conditions.

[0159] The electrolysis operation mode includes but is not limited to electrolysis of active oxygen and electrolysis of active chlorine. It is adjusted according to the needs of water purification by changing the catalytic coating material on the electrode surface. The electrolysis of active oxygen mainly produces ozone (O3), hydrogen peroxide (H2O2), hydroxyl (·OH) and other effective substances, and the electrolysis of active chlorine mainly produces Cl2, HClO and ClO- and other effective substances. The electrolysis operation parameters include but are not limited to the operating voltage and electrolysis time, which are affected by water quality conditions and the amount of condensed water. Here, Figure 2 The Electrolysis Module topic is used for example illustration.

[0160] Specifically, Y0 is defined as a threshold value for distinguishing the priority of the electrolysis mode (i.e., whether the active oxygen mode is dominant or the active chlorine mode is dominant). When Y≤Y0, it indicates that the existing water quality conditions are conducive to the generation of active oxygen, and the electrolysis module mainly operates in the electrolysis active oxygen mode. At this time, the electrolysis module of the water receiving tray is controlled to work on the electrolysis active oxygen electrode pair (i.e., electrode pair 1), and is powered on at the first voltage V1 until the operation time under the second preset condition reaches the second preset time t2. At this time, the electrolysis module mainly produces a large amount of active bactericidal substances such as H2O2 by catalytic electrolysis at the cathode; the second preset condition is that the electrolysis module actually has current passing through (i.e., electrolysis occurs); the first voltage V1 and the second preset time t2 are inversely correlated (i.e., the time decreases as the voltage increases, and vice versa), which is related to the water quality condition Y and the condensed water content (same as the first preset time), i.e., V1×t2=f2(Y, t1). In the specific control process, voltage control can be the main control, and time adjustment can be the auxiliary control, that is, the voltage and time range are determined according to the water quality conditions and the condensed water content, and the time is determined by controlling the voltage. It is easy for people in this field to understand that the better the water quality conditions (parameter Y), the more condensed water content (parameter t1), theoretically the more active substances produced by electrolysis, the better the effect, at which time the voltage (parameter V1) and time (parameter t2) can be reduced accordingly. Then the electrolysis module is turned off until the standing time under the third preset condition reaches the third preset time t3, so that the active bactericidal substances produced by electrolysis in the condensed water and the harmful microorganisms in the water receiving tray can fully react to achieve the best purification effect. The third preset time is related to the content of electrolytic active substances (i.e., the second preset time), i.e., t3=f3(t2).

[0161] When Y>Y0, it means that the existing water quality conditions are conducive to the generation of active chlorine, and the electrolysis module mainly operates in the electrolysis active chlorine mode. At this time, the water receiving tray electrolysis module electrolyzes the active chlorine electrode pair (i.e., electrode pair 2) to work, and is powered on at the second voltage V2 until the operating time under the fourth preset condition reaches the fourth preset time t4. At this time, the electrolysis module mainly produces a large amount of active bactericidal substances such as hypochlorous acid by catalytic electrolysis at the anode; the fourth preset condition is that the electrolysis module actually has current passing through it (i.e., electrolysis occurs); the second voltage V2 and the fourth preset time t4 are inversely correlated, and are related to the water quality condition Y and the condensed water content, i.e., V2×t4=f4(Y, t1). In the specific control process, voltage control can be the main control, and time adjustment can be the auxiliary control, that is, the voltage and time range are determined according to the water quality conditions and the condensed water content, and the time is determined by controlling the voltage. Then turn off the electrolysis module until the standing time under the fifth preset condition reaches the fifth preset time t5, so that the active bactericidal substances produced by electrolysis in the condensed water can fully react with harmful microorganisms in the water receiving tray to achieve the best purification effect. The fifth preset time is related to the content of electrolytic active substances (i.e., the fourth preset time), i.e., t5=f5(t4).

[0162] C\Control the electrolysis module to operate according to the corresponding mode and parameters.

[0163] Optionally, after judging in combination with water quality conditions whether the electrolysis module is operating in one of the modes, such as electrolysis of active chlorine or electrolysis of active oxygen, it can also continue to operate in another mode to make full use of the electrolysis of condensed water to produce the maximum bactericidal and purification effect. At this time, the water quality condition is the water quality condition Y' after electrolysis, that is, the original water quality Y needs to be electrolyzed and corrected before the operating parameters are determined again.

[0164] 3) Drying process

[0165] The drain nozzle valve of the water receiving pan of the air conditioner is controlled to open, and the condensed water is discharged. At the same time, the air conditioner is converted from the cooling mode to the heating mode, and the internal fan is controlled to operate at the second wind speed v2, and the compressor is controlled to operate at the second frequency p2, until the operation time under the sixth preset condition reaches the sixth preset time.

[0166] Time t6 is used to dry the condensed water between the fins and in the water receiving tray, so as to avoid the condensed water remaining in the water receiving tray, causing the water receiving tray to be dirty and contaminated by microorganisms, and other problems to occur again.

[0167] 5. Control the air conditioner to operate according to corresponding parameters and modes.

[0168] Specifically, according to user instructions or the air conditioner automatically detects the degree of dirtiness of the water tray, when the degree of dirtiness of the water tray exceeds the necessary limit, the air conditioner is controlled to operate at a certain wind speed, frequency, etc. based on the degree of pollution to produce a certain amount of condensed water, and at the same time detects its electrolysis water quality conditions, and then controls the electrolysis module to determine the best electrolysis operation mode and parameters based on the water quality conditions to produce enough of the most efficient active bactericidal substances, and maintains them for a certain period of time so that harmful microorganisms are fully purified, and then controls the air conditioner to operate in a heating mode with a certain wind speed, frequency, etc. to dry the moisture in the water tray and other areas inside the air conditioner, thereby completing the self-cleaning process of the water tray.

[0169] Furthermore, when it is determined that the water tray does not need to be self-cleaned or the water tray self-cleaning procedure is completed, the air conditioner is controlled to operate cooling and heating modes normally according to user needs, and the degree of contamination of the water tray is detected in real time or periodically, and then the water tray self-cleaning mode is executed again as needed.

[0170] Through this specific embodiment, the application process of the control method in the air conditioner is introduced in detail. The method can judge the degree of dirtiness of the water receiving tray according to user requirements or in combination with its own operating status, and when the degree of dirtiness of the water receiving tray exceeds the necessary limit, the air conditioner is controlled to produce condensed water, and the optimal electrolysis operation mode and parameters are determined by detecting the water quality conditions of the condensed water. Then, the air conditioner is controlled to operate according to the optimal electrolysis sterilization scheme and parameters to produce sufficient optimal active bactericidal substances to remove harmful microorganisms in the water receiving tray. After that, the water receiving tray is fully dried to avoid secondary bacterial growth to execute the water receiving tray self-cleaning program, thereby realizing long-term self-cleaning of the water receiving tray, and it is efficient, durable and non-consumable, ensuring the health of users.

[0171] Embodiment 6

[0172] On the basis of the above-mentioned embodiment, this embodiment provides another specific application embodiment of the air-conditioning water channel self-cleaning control method.

[0173] like Fig.14 As shown, the control method includes the following process:

[0174] When the air conditioner is powered on and runs in cooling (or dehumidification) mode, condensed water is generated during operation. The condensed water flows through the water quality sensor to detect the water quality and determine the best electrolysis sterilization scheme. At the same time, the electrodes of the electrolysis module are turned on to generate electrolysis according to the best electrolysis scheme to produce active bactericidal substances that flow through the entire water receiving tray with the condensed water to purify the docking water tray. That is, no water storage valve related to the water receiving tray is set, and no special control is performed on the electrolysis module. As long as condensed water is generated, the electrolysis module starts to work to purify and sterilize the docking water tray. In this way, as long as the air conditioner is running and condensed water is generated, the water receiving tray self-cleaning process can be carried out synchronously.

[0175] When the air conditioner is powered on and runs in heating mode (normal operation will not produce condensed water at this time) or receives a self-cleaning instruction from the user for the water tray, the air conditioner is controlled to cool and produce condensed water, and then the electrolytic sterilization and drying processes are performed as described above to achieve thorough sterilization and cleaning of the water tray.
