Description

Technical Field

[0001] The present invention relates to the technical field of air conditioner cleaning, and in particular to a control method and system for cleaning an air conditioner based on negative ion detection and intelligent startup. Background Art

[0002] With the improvement of people's living standards, air conditioners have become one of the indispensable household appliances in modern families, especially in hot summer and cold winter. Air conditioners not only bear the task of temperature regulation, but also become an important tool for air quality regulation. However, as a long-term operating device, air conditioners will inevitably accumulate dust, mold and other harmful substances during use. These substances are usually deposited on the filter, pipes and other parts of the air conditioner. They may be blown away with the flow of air, thereby polluting the indoor air and affecting the health of the living environment. Especially for people with allergies and asthma, these tiny particulate matter may cause or aggravate health problems.

[0003] Existing self-cleaning air conditioners mostly rely on the user's active operation or automatically start the self-cleaning function after a specific time set by the air conditioner. Although some air conditioners have the function of scheduled cleaning, they lack the ability to monitor air quality in real time and make intelligent judgments. The cleaning operation is based on a preset time or manual trigger by the user, rather than based on changes in air quality or the accumulation of pollutants inside the air conditioner. Summary of the invention

[0004] In view of the above-mentioned defects, the purpose of the present invention is to propose a control method and system for cleaning air conditioners based on negative ion detection and intelligent start-up, aiming to overcome the problem that the self-cleaning function in the prior art lacks pertinence and intelligence, so that the air conditioner can perform cleaning operations autonomously and accurately based on real-time monitoring of air quality, thereby improving the use efficiency and air quality of the air conditioner and extending the service life of the air conditioner.

[0005] To achieve this object, the present invention adopts the following technical solutions:

[0006] A control method for cleaning an air conditioner based on negative ion detection and intelligent startup, the control method comprising the following steps:

[0007] S1: Get the negative ion concentration in the room where the air conditioner is currently located;

[0008] S2: Establishing a communication connection between the mobile terminal and the air conditioner, wherein the communication connection is used to transmit a control signal between the mobile terminal and the air conditioner;

[0009] S3: according to the operation mode of the air conditioner and the comparison result of the negative ion concentration with the preset concentration standard, the air conditioner performs a cleaning operation on the filter screen and the pipe immediately or after a certain time interval, and performs the cleaning operation again and / or adjusts the time interval according to the result of the cleaning operation;

[0010] Wherein, the operation modes include a humidification module, a ventilation mode and a cooling mode.

[0011] Preferably, in step S2, when the operation mode of the air conditioner is the air exchange mode:

[0012] If it is detected that the negative ion concentration is less than the preset concentration standard, a cleaning operation is first performed on one of the filter screen and the air conditioning duct;

[0013] After the first time interval for performing the cleaning operation is completed, the negative ion concentration in the room where the current air conditioner is located is obtained, and if the negative ion concentration is greater than the preset concentration standard, the next time the negative ion concentration is detected to be less than the preset concentration standard, the other one of the filter and the air conditioning duct is cleaned;

[0014] After the first time interval for performing the cleaning operation is completed, the negative ion concentration in the room where the current air conditioner is located is obtained. If the negative ion concentration increases compared to before the cleaning operation is performed and is less than the preset concentration standard, a cleaning operation is performed on the other one of the filter and the air conditioning duct.

[0015] Preferably, in step S2, when the operation mode of the air conditioner is the cooling mode, when it is detected that the negative ion concentration is less than a preset concentration standard:

[0016] Get the running progress of cooling mode;

[0017] If the running progress of the cooling mode is less than half, the air conditioner stops running the cooling mode and sends a waiting-to-clean signal to the mobile terminal. If the mobile terminal returns a cleaning permission signal, the filter and the air conditioning pipe are cleaned and the air conditioner continues to run the cooling mode. If the mobile terminal returns a cleaning rejection signal, the air conditioner continues to run the cooling mode and performs the first operation, and performs the cleaning operation on the filter and the air conditioning pipe after receiving the cleaning permission signal sent back by the mobile terminal.

[0018] If the running progress of the cooling mode is more than half, the first operation is performed, and if the mobile terminal returns a cleaning permission signal, the filter and the air conditioning pipe are cleaned;

[0019] The first operation includes sending a signal to be cleaned to the mobile terminal after a second time interval after the running progress of the cooling mode reaches 100%.

[0020] Furthermore, the method further includes re-obtaining the negative ion concentration in the room where the current air conditioner is located after performing the first operation and performing a cleaning operation on the filter screen and the air conditioner pipe;

[0021] If the negative ion concentration is still lower than the preset concentration standard, the second time interval in the first operation is extended to a third time interval. After the operation progress of the subsequent refrigeration mode reaches 100%, the filter and the air-conditioning duct can be cleaned at least after the third time interval.

[0022] Preferably, in step S2, when the operation mode of the air conditioner is the humidification mode and it is detected that the negative ion concentration is less than the preset concentration standard, the air conditioner stops running the humidification mode and sends a signal to be cleaned to the mobile terminal;

[0023] If the mobile terminal returns a cleaning permission signal, the second operation is performed;

[0024] If the mobile terminal returns a signal to reject cleaning, the air conditioner continues to operate in the humidification mode, and after the humidification mode automatically stops operating, the third operation is performed;

[0025] The second operation includes setting a fourth time interval according to the running time of the humidification mode, and performing a cleaning operation on the filter screen and the air conditioning duct after the fourth time interval;

[0026] The third operation includes setting a fifth time interval according to the operation duration of the humidification mode, and performing a cleaning operation on the filter screen and the air conditioning duct after the fifth time interval.

[0027] Furthermore, the method further includes re-obtaining the negative ion concentration in the room where the air conditioner is currently located after executing the second operation or the third operation;

[0028] If after performing the second operation, the negative ion concentration is still lower than the preset concentration standard and / or after performing the third operation, the negative ion concentration is still lower than the preset concentration standard, then the time interval in the second operation and / or the third operation is extended;

[0029] The fifth time interval is not less than the fourth time interval.

[0030] Further, setting the fourth time interval according to the running time of the humidification mode and setting the fifth time interval according to the running time of the humidification mode satisfy the relationship:

[0031]

[0032] Wherein, T represents the fourth time interval or the fifth time interval, a1 represents the linear relationship strength between the humidification time and the output value, and T humid Indicates the running time of the humidification mode, b1 indicates the influence of the square of the humidification time on the output value, and b2 indicates the basic time length when the humidification time is 0.

[0033] Preferably, if after cleaning the filter and the air conditioning duct, the negative ion concentration in the room where the air conditioner is currently located is still lower than the preset concentration standard, the cleaning operation is performed on the filter and the air conditioning duct in a cycle until the negative ion concentration in the room where the air conditioner is currently located is not lower than the preset concentration standard.

[0034] Furthermore, if the number of cycles reaches a preset cycle standard, a manual cleaning signal is sent to the user.

[0035] A control system based on negative ion detection and intelligent start-up of a clean air conditioner, the control system is applied to the control method as described above, and the control system comprises:

[0036] The detection module is used to obtain the negative ion concentration in the room where the air conditioner is currently located;

[0037] A communication module, used to establish a communication connection between the mobile terminal and the air conditioner, wherein the communication connection is used to transmit control signals between the mobile terminal and the air conditioner;

[0038] A cleaning control module, for performing a cleaning operation on the filter screen and the pipe of the air conditioner immediately or after a certain time interval according to the operation mode of the air conditioner and the comparison result of the negative ion concentration with the preset concentration standard, and performing the cleaning operation again and / or adjusting the time interval according to the result of the cleaning operation;

[0039] Wherein, the operation modes include a humidification module, a ventilation mode and a cooling mode.

[0040] One of the above technical solutions has the following advantages or beneficial effects:

[0041] By combining real-time negative ion concentration monitoring, air-conditioning operation mode judgment and time interval adjustment, the air conditioner can intelligently determine the timing and frequency of cleaning operations; the air conditioner operation mode and humidity data provide a basis for optimizing the timing of cleaning operations. By combining these factors, the air conditioner can not only intelligently start the cleaning function according to the air quality, but also adjust the cleaning timing according to the operating status, thereby ensuring the efficiency and accuracy of each cleaning operation; in addition, through intelligent control and remote operation, users can monitor the cleaning status of the air conditioner in real time and adjust it according to personal needs, which can improve the intelligence level of the air conditioner and user experience.

[0045] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0046] In this application, the terms "comprises", "comprising" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0047] With the improvement of people's living standards, air conditioners have become one of the indispensable household appliances in modern families, especially in hot summer and cold winter. Air conditioners not only bear the task of temperature regulation, but also become an important tool for air quality regulation. However, as a long-term operating device, air conditioners will inevitably accumulate dust, mold and other harmful substances during use. These substances are usually deposited on the filter, pipes and other parts of the air conditioner. They may be blown away with the flow of air, thereby polluting the indoor air and affecting the health of the living environment. Especially for people with allergies and asthma, these tiny particulate matter may cause or aggravate health problems.

[0048] Existing self-cleaning air conditioners mostly rely on the user's active operation or automatically start the self-cleaning function after a specific time set by the air conditioner. Although some air conditioners have the function of scheduled cleaning, they lack the ability to monitor air quality in real time and make intelligent judgments. The cleaning operation is based on a preset time or manual trigger by the user, rather than based on changes in air quality or the accumulation of pollutants inside the air conditioner.

[0049] Therefore, a control method based on negative ion detection and intelligent start-up of clean air conditioner is proposed. Figure 1 As shown, in a preferred embodiment of the present invention, the control method comprises the following steps:

[0050] S1: Get the negative ion concentration in the room where the air conditioner is currently located;

[0051] Negative ions are negatively charged particles in the air, usually produced by natural phenomena such as waterfalls, lightning or waves. Negative ions have the ability to absorb fine dust, bacteria, viruses and other harmful substances in the air, so they are believed to be able to purify the air and improve air quality. In an air-conditioned environment, the level of negative ion concentration can reflect the cleanliness of the indoor air. If the negative ion concentration is low, it means that there is more dust, allergens or pollutants suspended in the air. By real-time monitoring of the negative ion concentration in the room where the air conditioner is located, the cleanliness of the air can be accurately assessed, thereby providing a scientific basis for whether the cleaning mechanism needs to be activated. The negative ion concentration can be detected by installing a negative ion sensor. The sensor can convert the number of negative ions in the air into a quantifiable value (such as pieces / cubic centimeter), providing data support for subsequent cleaning decisions.

[0052] S2: Establishing a communication connection between the mobile terminal and the air conditioner, wherein the communication connection is used to transmit a control signal between the mobile terminal and the air conditioner;

[0053] The communication connection between the air conditioner and the mobile device is the key to realize remote control and data interaction. Through wireless communication technology (such as Wi-Fi, Bluetooth, ZigBee, etc.), the mobile terminal can connect to the air conditioning system in real time, obtain information such as the working status of the air conditioner, internal temperature and humidity, negative ion concentration, and send control instructions. The mobile terminal can be a smart phone, tablet computer and other devices. Users can use these devices to view the real-time information of the air conditioner, adjust the air conditioner settings, and even manually or automatically trigger cleaning operations when the air quality is poor. The establishment of a communication connection not only makes the air conditioner more intelligent, but also improves the operation and maintenance efficiency of the air conditioner through cloud updates, remote diagnosis and other functions, reduces manual intervention, and improves user experience.

[0054] S3: performing a cleaning operation on the filter screen and the pipe of the air conditioner immediately or after a certain time interval according to the operation mode of the air conditioner and the comparison result of the negative ion concentration with the preset concentration standard, and performing the cleaning operation again and / or adjusting the time interval according to the result of the cleaning operation;

[0055] Wherein, the operation modes include a humidification module, a ventilation mode and a cooling mode.

[0056] In this embodiment, the cleaning operation of the air conditioner is based on electrostatic cleaning technology, and the electrostatic cleaning technology is used to remove stains and dust in the filter and the pipe. The cleaning operations of the filter and the air conditioning pipe are both internal cleaning methods of the air conditioner.

[0057] By comprehensively considering the operating mode of the air conditioner and the real-time monitoring of the negative ion concentration, it is determined whether the cleaning operation needs to be started. The operating mode of the air conditioner (such as cooling, humidification, ventilation, etc.) will affect the humidity, temperature and other parameters in the air, which may affect the cleaning effect of the air conditioner. For example, when the air conditioner is in humidification or cooling mode, moisture is easily accumulated inside, which will reduce the effect of electrostatic cleaning technology, because moisture will cause the failure of static electricity, so it is necessary to clean it at the right time. The negative ion concentration reflects the indoor air quality. When it is lower than the preset standard concentration, it means that a large amount of harmful substances may accumulate in the air, and the air conditioner's filter or pipes may also accumulate a lot of dust and microorganisms. At this time, a cleaning operation needs to be performed. The air conditioner automatically determines the timing of cleaning based on these data, which can significantly improve the real-time and accuracy of air conditioning cleaning and avoid the inconvenience caused by human intervention.

[0058] The timing of the cleaning operation not only depends on the air quality (negative ion concentration), but also needs to consider the impact of the air conditioner's operating mode on the internal environment of the air conditioner. In humidification mode and cooling mode, moisture may accumulate inside the air conditioner, increasing the internal humidity, and excessive moisture will affect the effect of electrostatic cleaning. Therefore, after humidification or cooling, you should wait for a certain time interval until the humidity inside the air conditioner gradually decreases and the electrostatic cleaning effect returns to normal before performing the cleaning operation. By adjusting the timing of the cleaning operation, the cleaning effect can be maximized. The timing of the cleaning operation can be intelligently adjusted according to the specific operating status of the air conditioner, humidity data, and external environmental factors (such as indoor temperature, humidity, etc.), thereby avoiding the negative impact of moisture on the cleaning effect.

[0059] Preferably, in step S2, when the operation mode of the air conditioner is the air exchange mode:

[0060] If it is detected that the negative ion concentration is less than the preset concentration standard, a cleaning operation is first performed on one of the filter screen and the air conditioning duct;

[0061] After the first time interval for performing the cleaning operation is completed, the negative ion concentration in the room where the current air conditioner is located is obtained, and if the negative ion concentration is greater than the preset concentration standard, the next time the negative ion concentration is detected to be less than the preset concentration standard, the other one of the filter and the air conditioning duct is cleaned;

[0062] After the first time interval for performing the cleaning operation is completed, the negative ion concentration in the room where the current air conditioner is located is obtained. If the negative ion concentration increases compared to before the cleaning operation is performed and is less than the preset concentration standard, a cleaning operation is performed on the other one of the filter and the air conditioning duct.

[0063] When the air conditioner detects that the indoor negative ion concentration is lower than the preset concentration standard, it means that the number of negative ions in the air is insufficient, the air quality is poor, and there may be more dust, bacteria, viruses and other harmful substances. At this time, the air conditioner starts the cleaning operation, and the filter or a certain component in the air conditioning duct is preferentially cleaned. The filter and the air conditioning duct are two key components of the air conditioning system, which are responsible for air filtration and air circulation respectively. By cleaning these components, dust and particles that may block or pollute air circulation can be removed, and the air quality can be improved, which helps to increase the concentration of negative ions.

[0064] After the cleaning operation is completed, the air conditioner sets a first time interval so that the cleaning effect can be fully manifested. The first time interval is not only to allow enough time for the cleaning work to be completed, but also to allow the air conditioning system to return to a stable state. After the time interval, the air conditioner will detect the negative ion concentration in the room again. If the concentration at this time has recovered and exceeded the preset standard, it means that the cleaning operation has effectively improved the air quality. In this case, the air conditioner will not continue to repeat the cleaning of the same component. Instead, in the next negative ion concentration detection, if the concentration is found to be lower than the preset standard again, it will turn to perform the cleaning operation on another component. In other words, the air conditioner will clean the filter and the pipe in turn to ensure that both components can be effectively cleaned and the air quality is optimized to the maximum extent.

[0065] If the negative ion concentration increases during the time interval after the cleaning operation, but is still lower than the preset standard, it means that the improvement in air quality is limited and there may be some pollution sources that have not been effectively cleaned. At this time, the air conditioner will clean another component (that is, the uncleaned filter or air conditioning duct). By cleaning another component, the air circulation efficiency and air quality will be further improved to ensure that even if the negative ion concentration does not fully meet expectations after cleaning, the air conditioning system can still be continuously optimized to gradually improve indoor air quality. The core purpose of this operation is to ensure that through repeated cleaning and monitoring processes, when the negative ion concentration continues to fail to meet the standard, the cleaning plan can be flexibly adjusted to gradually achieve the ideal air quality.

[0066] Assuming that the air conditioner is currently running in the ventilation mode, and detects that the indoor negative ion concentration is lower than the preset standard, it means that the air quality is poor. At this time, the air conditioner will first clean the filter to remove pollutants such as accumulated dust and bacteria, thereby improving air circulation and freshness. After the cleaning operation is completed, the air conditioner will wait for a period of time (for example, 30 minutes) and then re-detect the negative ion concentration. If the negative ion concentration rises at this time and exceeds the preset standard, it means that the cleaning operation is effective and the air quality has improved. The air conditioner will stop the cleaning operation and wait for the next negative ion concentration to drop. However, if the negative ion concentration is still lower than the standard, the air conditioner will continue the cleaning operation. This time it will choose to clean the air conditioning ducts, first choose one part to clean, and if the effect is not obvious, clean another one, to ensure that the air quality is comprehensively improved while saving energy.

[0067] Preferably, in step S2, when the operation mode of the air conditioner is the cooling mode, when it is detected that the negative ion concentration is less than a preset concentration standard:

[0068] Get the running progress of cooling mode;

[0069] If the running progress of the cooling mode is less than half, the air conditioner stops running the cooling mode and sends a waiting-to-clean signal to the mobile terminal. If the mobile terminal returns a cleaning permission signal, the filter and the air conditioning pipe are cleaned and the air conditioner continues to run the cooling mode. If the mobile terminal returns a cleaning rejection signal, the air conditioner continues to run the cooling mode and performs the first operation, and performs the cleaning operation on the filter and the air conditioning pipe after receiving the cleaning permission signal sent back by the mobile terminal.

[0070] If the running progress of the cooling mode is more than half, the first operation is performed, and if the mobile terminal returns a cleaning permission signal, the filter and the air conditioning pipe are cleaned;

[0071] The first operation includes sending a signal to be cleaned to the mobile terminal after a second time interval after the running progress of the cooling mode reaches 100%.

[0072] When the air conditioner is in cooling mode, it will first continuously monitor its running progress, which refers to the percentage of cooling tasks completed from the time the air conditioner is turned on to the current moment. For example, if the cooling time of the air conditioner is set to 2 hours, then after 1 hour, the running progress is 50%, or if the cooling temperature of the air conditioner is set to 24°C, the air conditioner calculates the cooling time or cooling capacity required when the temperature reaches 24°C before cooling, and calculates the cooling progress while cooling.

[0073] If the air conditioner detects that the progress of the cooling mode is less than 50%, it means that the air conditioner is still in the first half of the cooling cycle. The humidity inside the air conditioner is low, which has little impact on the cleaning effect. At this time, the air conditioner will stop the current cooling operation and send a cleaning request signal (to-be-cleaned signal) to the connected mobile terminal. At this time, the main purpose of the air conditioner is to ensure the improvement of air quality before resuming cooling operation. After sending the to-be-cleaned signal, the air conditioner will wait for the response of the mobile terminal. The mobile terminal can decide whether to perform the cleaning operation according to the user's needs. If the user allows cleaning, the air conditioner will continue to perform the cleaning operation. The cleaning operation includes cleaning the filter and air conditioning ducts to ensure that air circulation is not hindered by pollutants. After the cleaning is completed, the air conditioner will restart the cooling mode and continue to operate.

[0074] If the user refuses the cleaning operation, the air conditioner will not terminate the cooling mode, but will continue to operate in the cooling mode and then perform the first operation.

[0075] If the air conditioner's running progress exceeds 50% (i.e. the cooling mode is approaching the second half), the air filter and pipes will become wet, which will have a greater impact on the cleaning effect of the electrostatic cleaning technology. The first operation will be automatically executed. The core content of the first operation is: even if the air quality is poor at this time, the air conditioner will continue to perform the cooling task instead of immediately interrupting the operation and waiting for cleaning. When the cooling mode running progress reaches 100%, the air conditioner will wait for the second time interval, that is, a period of time after the air conditioner completes the cooling task, and send a signal to be cleaned to the mobile terminal again.

[0076] Furthermore, the method further includes re-obtaining the negative ion concentration in the room where the current air conditioner is located after performing the first operation and performing a cleaning operation on the filter screen and the air conditioner pipe;

[0077] If the negative ion concentration is still lower than the preset concentration standard, the second time interval in the first operation is extended to a third time interval. After the operation progress of the subsequent refrigeration mode reaches 100%, the filter and the air-conditioning duct can be cleaned at least after the third time interval.

[0078] If after the cleaning operation, the indoor negative ion concentration is still lower than the preset standard, it may be because the refrigeration operation causes the moisture in the air to condense into water, forming a certain humid environment. When performing the cleaning operation, the filter and air-conditioning pipes are damp, and the electrostatic cleaning technology is inefficient, so the indoor negative ion concentration is still lower than the preset concentration standard. Therefore, it is necessary to extend the second time interval. Extending the time can allow the moisture generated by the air conditioner in the cooling mode to evaporate for more time, thereby avoiding the interference of the humid environment on the cleaning process.

[0079] Assume that in a certain air conditioning system, after the cooling mode is completed, a cleaning operation is performed. At this time, the air conditioner cleans the filter and air conditioning pipes, and re-measures the negative ion concentration in the room. It is found that after the cleaning operation, the negative ion concentration is still lower than the preset standard (for example, the preset standard is 1000 negative ions per cubic centimeter, and the actual concentration is 800). Therefore, it is decided to extend the second time interval originally set in the first operation (assuming 10 minutes) to a third time interval (for example, 15 minutes). When the cooling mode operation progress reaches 100% later, the air conditioner will not immediately perform the cleaning operation again, but wait for at least 60 minutes before performing the next cleaning of the filter and air conditioning pipes. This delay time helps to allow moisture to evaporate fully and avoid the influence of the humid environment on the cleaning effect, thereby increasing the negative ion concentration and optimizing the air quality.

[0080] Preferably, in step S2, when the operation mode of the air conditioner is the humidification mode and it is detected that the negative ion concentration is less than the preset concentration standard, the air conditioner stops running the humidification mode and sends a signal to be cleaned to the mobile terminal;

[0081] If the mobile terminal returns a cleaning permission signal, the second operation is performed;

[0082] If the mobile terminal returns a signal to reject cleaning, the air conditioner continues to operate in the humidification mode, and after the humidification mode automatically stops operating, the third operation is performed;

[0083] The second operation includes setting a fourth time interval according to the running time of the humidification mode, and performing a cleaning operation on the filter screen and the air conditioning duct after the fourth time interval;

[0084] The third operation includes setting a fifth time interval according to the operation duration of the humidification mode, and performing a cleaning operation on the filter screen and the air conditioning duct after the fifth time interval.

[0085] Since the current operating mode of the air conditioner is the humidification mode, the humidity inside the air conditioner is relatively high during any operating time of the humidification mode. Therefore, if the negative ion concentration is detected to be lower than the preset concentration standard, the current mode can be stopped immediately and the cleaning operation can be performed.

[0086] In the second operation, the air conditioner will set a fourth time interval according to the running time of the humidification mode (for example, the humidification has been running for 5 minutes, 8 minutes, etc.). This time interval is designed to ensure that the moisture generated in the humidification mode is fully dissipated, thereby avoiding the negative impact of the humid environment on the cleaning operation. The longer the humidification mode runs, the more time it takes to wait for the inside of the air conditioner to become dry. When there is too much moisture, the cleaning operation may not achieve the desired effect and may even cause mold or bacteria to grow. After setting the fourth time interval, the air conditioner will perform a cleaning operation on the filter and air conditioning duct after this time period. Doing so will help to fully evaporate the moisture, ensure that the cleaning operation is more effective, and reduce the impact of moisture on air quality.

[0087] In the third operation, if the user refuses the cleaning operation, the air conditioner continues to run the humidification mode until the humidification mode stops automatically. After the humidification mode ends, the air conditioner performs the third operation, that is, setting a fifth time interval. Similar to the fourth time interval, the purpose of setting the fifth time interval is to give the air conditioner a certain amount of time after the humidification mode ends to completely dissipate the moisture in the air.

[0088] Once the humidification mode is completely stopped and the fifth time interval has passed, the air conditioner will perform a cleaning operation, which ensures that the impact of moisture on cleaning is minimized, allowing the cleaning operation to proceed smoothly in a dry environment, improving the cleaning effect and preventing new pollution from being caused by a humid environment.

[0089] In this embodiment, the fourth and fifth time intervals are greater than the second and third time intervals.

[0090] Furthermore, the method further includes re-obtaining the negative ion concentration in the room where the air conditioner is currently located after executing the second operation or the third operation;

[0091] If after performing the second operation, the negative ion concentration is still lower than the preset concentration standard and / or after performing the third operation, the negative ion concentration is still lower than the preset concentration standard, then the time interval in the second operation and / or the third operation is extended;

[0092] The fifth time interval is not less than the fourth time interval.

[0093] After performing the second operation, if the negative ion concentration in the room is still lower than the preset standard (for example, the set concentration is 1000 negative ions / cubic centimeter), it means that the cleaning effect may not be obvious, and moisture or pollutants are still in the air, causing the negative ion concentration to be unable to return to normal levels. At this time, the time interval in the second operation is extended. Similarly, if the negative ion concentration still cannot reach the preset standard after the third operation is performed, it means that even if the cleaning operation is performed after the fifth time interval after the humidification mode ends, the air quality still fails to improve significantly. In this case, the time interval in the third operation is extended. By extending the time interval, wait for the humidity in the air conditioner to be sufficiently reduced, and then perform the cleaning operation, so as to achieve a better cleaning effect.

[0094] The fifth time interval represents the setting after the full humidification mode is completed. Therefore, the fifth time interval is greater than or equal to the fourth time interval. If the second operation is performed continuously, resulting in the fourth time interval being extended to be greater than the fifth time interval, then the fifth time interval also needs to be extended accordingly, at least not less than the fourth time interval.

[0095] Further, setting the fourth time interval according to the running time of the humidification mode and setting the fifth time interval according to the running time of the humidification mode satisfy the relationship:

[0096]

[0097] Wherein, T represents the fourth time interval or the fifth time interval, a1 represents the linear relationship strength between the humidification time and the output value, and T humid Indicates the running time of the humidification mode, b1 indicates the influence of the square of the humidification time on the output value, and b2 indicates the basic time length.

[0098] Specifically, assuming that the operating time of the humidification mode is T humid It is 10 minutes. According to the experiment, the linear relationship strength a1 between the humidification time and the output value of a certain air conditioner is 0.5, the influence degree b1 of the square of the humidification time on the output value is 0.03, the basic time length b2 is 2, and when the humidification mode runs for 10 minutes, the fourth time interval or the fifth time interval is 10 minutes.

[0099] In another embodiment, if after the filter and the air-conditioning duct are cleaned, the negative ion concentration in the room where the air-conditioning is currently located is still lower than the preset concentration standard, the filter and the air-conditioning duct are cleaned in a cycle until the negative ion concentration in the room where the air-conditioning is currently located is no lower than the preset concentration standard.

[0100] If the negative ion concentration reaches the preset standard after the cleaning operation, the cleaning process ends and the air conditioner operates normally; if the concentration is still lower than the standard, it means that the cleaning effect is not sufficient, which may be due to pollutants in the filter or pipes that still affect the air flow and the release of negative ions. When the negative ion concentration does not reach the preset standard, the filter and pipe cleaning operation will be automatically re-performed. This process will continue in a cycle until the negative ion concentration is detected to meet the standard. The cyclic cleaning mechanism ensures that each cleaning operation can effectively increase the negative ion concentration until the ideal air quality level is reached.

[0101] Furthermore, if the number of cycles reaches a preset cycle standard, a manual cleaning signal is sent to the user.

[0102] In order to avoid over-cleaning or a decrease in cleaning effect due to other factors, a maximum number of cycles is set. If the number of cycles reaches this preset upper limit, it is judged that the current automatic cleaning operation may not completely solve the problem of low negative ion concentration. At this time, a manual cleaning signal will be sent to the user to prompt the user to intervene manually. The manual cleaning signal can remind the user to check the filter, pipes or other potential problems of the air conditioning equipment, such as equipment failure or excessive pollution, to ensure that the air conditioning resumes normal operation. Through this mechanism, a balance can be maintained between automatic cleaning and manual intervention to ensure that the negative ion concentration and air quality can always meet the standards.

[0104] Detection module 1, used to obtain the negative ion concentration in the room where the air conditioner is currently located;

[0105] Communication module 2, used to establish a communication connection between the mobile terminal and the air conditioner, wherein the communication connection is used to transmit control signals between the mobile terminal and the air conditioner;
