Description

Technical Field

[0001] The present invention relates to the technical field of air conditioners, and in particular provides a control method of an air conditioner and an air conditioner. Background Art

[0002] After an air conditioner has been used for a long time, it is easy for an odor to form inside. The traditional method is to use air conditioner cleaner to clean it, which is not only cumbersome but also not economical.

[0003] To solve the above problems, many existing air conditioners are designed with ozone generators. When removing odors, ozone generators quickly generate high-concentration ozone, which can effectively kill bacteria and remove odors after diffusion. However, high-concentration ozone is extremely harmful to the human body. While sterilizing and removing odors, it also poses safety risks. Summary of the invention

If it is determined that the user is about to return, the control system will immediately instruct the air conditioner to exit the ozone deodorization mode. In the above manner, the time for the air conditioner to exit the ozone deodorization mode is reasonably controlled. Such a design can ensure that the indoor ozone has been fully dissipated before the user arrives home, thereby effectively preventing the user from being exposed to high concentrations of ozone that may be generated during the ozone deodorization process, which is beneficial to protecting the health and safety of the user.

BRIEF DESCRIPTION OF THE DRAWINGS

[0049] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings, in which:

[0050] Figure 1 A flowchart of a method for controlling an air conditioner provided in Embodiment 1 of the present invention;

[0051] Figure 2 This is a detailed flow chart of the air conditioner control method provided in Example 2 of the present invention. DETAILED DESCRIPTION

[0052] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not used to limit the scope of protection of the present invention. Those skilled in the art can make adjustments as needed to adapt to specific applications. In order to better illustrate the present invention, numerous specific details are given in the specific embodiments below. It should be understood by those skilled in the art that the present invention can also be implemented without certain specific details.

[0053] An embodiment of the present invention provides an air conditioner, which includes an ozone generator, a circulating fan, a heating module, a fresh air module, etc. Among them, the ozone generator can generate ozone, and the ozone can react with organic matter in the air to achieve the effects of sterilization, disinfection, and deodorization. The circulating fan can generate airflow, so that ozone can be more easily diffused and spread throughout the internal space of the air conditioner, which is conducive to removing the odor inside the air conditioner. The heating module can increase the temperature of the air, accelerate the self-heating decomposition process of ozone, and help to quickly reduce the indoor ozone concentration. The fresh air module can introduce fresh air from the outside to replace the indoor ozone to the outside, thereby diluting the indoor ozone concentration.

[0054] Example 1

[0055] Based on the above air conditioner, please refer to Figure 1 , which shows the main steps of a control method for an air conditioner provided by the present invention, the control method comprising:

[0056] S1. When the ozone generator is turned on and the user is away from home, obtain the user's first real-time distance from home.

[0057] The first process of obtaining the real-time distance from home: the GPS (Global Positioning System) module of a smartphone or other smart device can be used to accurately capture the user's current real-time latitude and longitude coordinates, and then the coordinates are compared and calculated with the fixed longitude and latitude information of the user's residence to obtain the user's real-time distance from home.

[0058] S2. Compare the first real-time distance from home with a first preset distance threshold.

[0059] Since different air conditioners may be designed for different user needs and usage scenarios, the value of the first preset distance threshold may also be different. The first preset distance threshold determines at which point in time the air conditioner starts the judgment procedure of whether to exit the ozone deodorization mode. The value of the first preset distance threshold is usually initially set by the designer through experimental testing, but it can also be intelligently adjusted according to the actual situation of the user.

[0060] S3. Determine whether to continuously detect and record multiple subsequent distances at a set frequency based on a comparison result of the first real-time distance from home and the first preset distance threshold.

[0061] Setting the frequency means recording the user's real-time distance from home at a predetermined time interval, that is, recording the user's real-time distance from home once every certain period of time. In this process, the number of data recordings is pre-set, such as setting it to record subsequent distance data for different times, such as 3 times, 4 times, or 5 times.

[0062] Step S3 includes step S31 and step S32, which are specifically as follows:

[0063] S31. If the first real-time distance from home is less than or equal to (or less than) the first preset distance threshold, continuously detect and record multiple subsequent distances at a set frequency, and execute step S4.

[0064] S32: If the first real-time distance from home is greater than (or greater than or equal to) the first preset distance threshold, return to step S1.

[0065] S4. Predicting the user's movement trend based on multiple subsequent distances.

[0066] By comprehensively analyzing a data set consisting of multiple subsequent distance data, we can derive the changing trend of the user's distance from home, and predict the user's movement trend based on this. For example, if the data analysis shows that the user's distance from home is gradually decreasing, it can be predicted that the user's movement trend is a return trend; otherwise, it is predicted that the user's movement trend is not a return trend.

[0067] S5. Determine whether the air conditioner should exit the ozone deodorization mode according to the movement trend. Specifically, it includes:

[0068] S51. If the movement trend is a return home trend, the air conditioner is exited from the ozone deodorization mode.

[0069] S52: If the movement trend is not a return-home trend, the air conditioner is controlled to maintain the original state and the process returns to step S1.

[0070] The control method of the air conditioner provided in this embodiment is that when the air conditioner enters the ozone deodorization mode, the user's first real-time distance from home is obtained, and it is compared with the first preset distance threshold. According to the comparison result, the control system of the air conditioner can intelligently determine whether the user is located in a surrounding area not far from the residence. If the first real-time distance from home is less than or equal to the first preset distance threshold, that is, the user is determined to be located in a surrounding area not far from the residence, and then a plurality of subsequent distances are continuously detected and recorded at a set frequency. The user's movement trend can be predicted through a plurality of subsequent distances, and then it is determined whether the user is about to return to the residence based on the movement trend. If it is determined that the user is about to return, the control system will immediately instruct the air conditioner to exit the ozone deodorization mode. In the above manner, the time for the air conditioner to exit the ozone deodorization mode is reasonably controlled. Such a design can ensure that the indoor ozone has been fully dissipated before the user arrives home, thereby effectively preventing the user from being exposed to high concentrations of ozone that may be generated during the ozone deodorization process, which is beneficial to protecting the health and safety of the user.

[0071] Example 2

[0072] Based on Example 1, Example 2 adds a second preset distance threshold and a comparison result between the remaining time and the preset time threshold to determine whether the air conditioner exits the ozone deodorization mode. Figure 2 , which shows the detailed steps of another air conditioner control method provided by the present invention, the control method comprises:

[0073] S101, obtaining indoor biological information and / or user's exit information. Specifically, the following three implementation methods can be adopted:

[0074] In the first implementation, only the biological information in the room is obtained, and whether the user is away from home is determined by judging whether the biological information exists in the room. If the biological information does not exist in the room, it is determined that the user is away from home.

[0075] Among them, indoor biological information can be obtained through radar, camera, infrared sensor, sound sensor or other detection equipment. Although ozone has strong oxidizing and sterilizing capabilities, it may also cause certain stimulation or harm to organisms. Before the ozone generator is turned on, by detecting indoor biological information, such as the biological information of humans and pets in the room, the ozone generator can be turned on when it is ensured that there are no organisms in the room, thereby avoiding unnecessary harm to organisms during ozone deodorization.

[0076] When installing the detection equipment, according to actual needs, the detection equipment can be installed only in the room where the air conditioner is located (such as a living room or bedroom), or in multiple rooms of the user's residence (such as a suite with multiple rooms, a duplex or a large residence). The various detection devices work together to complete the process of the air conditioner obtaining indoor biological information.

[0077] In the second implementation, only the user's going-out information is obtained, and whether the user has gone out is determined according to the user's going-out information, so as to judge whether the user is away from home. If it is determined according to the going-out information that the user has gone out, it is judged that the user is away from home.

[0078] Among them, the user's going-out information can be obtained through smart door locks, camera monitoring, mobile phone positioning, etc. The user can be one or more. By detecting the going-out information of all users, it is ensured that all users have left the indoor environment before turning on the ozone generator. In this way, by staggering the time when the user is indoors, it is ensured that the ozone generator is turned on when the user is not present, which can avoid the potential harm of ozone when the user is indoors and ensure the health and safety of the user.

[0079] In a third implementation, the indoor biometric information and the user's out-of-home information are obtained at the same time, and the comprehensive information of the indoor biometric information and the user's out-of-home information is analyzed to determine whether the user is away from home. When there is no biometric information indoors and it is determined that the user has gone out according to the out-of-home information, it is determined that the user is away from home.

[0080] By adopting the third implementation mode, the biometric information data and the user's out-of-home information can be integrated to more accurately determine whether the user is away from home.

[0081] Among them, biological information can be body temperature, movement speed, etc.

[0082] S102: Based on the biometric information and / or the going-out information, determine whether the user is away from home. If the determination result is yes, execute step S103; if the determination result is no, return to execute step S101.

[0083] S103: Obtain the user's second real-time distance from home.

[0084] The process of obtaining the second real-time distance from home is the same as the process of obtaining the first real-time distance from home, and the details may refer to step S1 of embodiment 1.

[0085] S104. Compare the second real-time distance from home with the third preset distance threshold, that is, determine whether the second real-time distance from home is greater than or equal to the third preset distance threshold. The third preset distance threshold is greater than the first preset distance threshold. This setting allows the ozone generator to be started only when the user's real-time distance from home exceeds the third preset distance threshold that is greater than the first preset distance threshold. This can reserve enough time for the air conditioner system to flexibly judge and decide whether to interrupt the ozone deodorization mode, ensuring the safety and rationality of the operation. If the comparison result is that the second real-time distance from home is greater than or equal to (or greater than) the third preset distance threshold, execute step S105; if the comparison result is that the second real-time distance from home is less than (or less than or equal to) the third preset distance threshold, return to execute step 103.

[0086] S105: Turn on the ozone generator, that is, the air conditioner enters the ozone deodorization mode.

[0087] It should be noted that before turning on the ozone generator, the historical frequency information of the user turning on the ozone deodorization mode by himself is obtained, and the turning-on state of the ozone generator is corrected according to the historical frequency information.

[0088] By analyzing the historical frequency of users turning on the ozone deodorization mode, the air conditioner system can understand the user's actual demand for air purification or odor removal, which helps the system make more accurate judgments to determine when and how often to start the ozone generator. Combined with real-time detection of biological information and exit information, the system can intelligently plan the operating time period of the ozone generator to ensure that efficient and personalized air purification services are provided while meeting user needs and not affecting user life.

[0089] At the same time or after turning on the ozone generator, close the air outlet guide of the air conditioner. After the air outlet guide of the air conditioner is closed, a relatively closed environment will be formed inside the air conditioner, which will help reduce the loss of ozone and increase the ozone concentration inside the air conditioner, thereby enhancing the deodorization and disinfection effects.

[0090] At the same time or after turning on the ozone generator, run the circulating fan of the air conditioner. The circulating fan runs at a low speed, and the airflow generated is relatively gentle, which helps the ozone to diffuse in the internal space of the air conditioner. This ensures that the ozone can fully contact every corner of the internal space of the air conditioner, improve the deodorization effect, and thus more effectively remove the odor inside the air conditioner.

[0091] In addition, when the ozone generator is in the on state, the control method includes:

[0092] S1051. Obtain a first indoor ozone concentration, compare the first ozone concentration with a first preset concentration threshold, and selectively start a heating module and / or a fresh air module based on the comparison result.

[0093] The indoor ozone concentration can be obtained by installing a first ozone concentration sensor or other measuring equipment indoors. The first preset concentration threshold needs to consider the potential impact of ozone on human health and the requirements of environmental standards, and the specific value is obtained by the designer through multiple experimental tests.

[0094] Specifically, when the first ozone concentration is compared with the first preset concentration threshold, if the first ozone concentration is greater than or equal to the first preset concentration threshold, the heating module and / or the fresh air module is started. In actual use, the heating module can be started alone, the fresh air module can be started alone, or the heating module and the fresh air module can be started at the same time.

[0095] When it is detected that the first indoor ozone concentration exceeds the first preset concentration threshold, starting the heating module can increase the indoor temperature, thereby accelerating the natural decomposition process of ozone, and helping to quickly reduce the indoor ozone concentration. Starting the fresh air module can introduce fresh air from the outside, dilute the indoor ozone concentration by displacement or mixing, and bring in sufficient oxygen to improve the indoor air quality. This not only helps to quickly diffuse ozone to the outdoors, but also ensures the freshness and circulation of indoor air, effectively avoiding direct contact between ozone and users, and further ensuring the safety and health of users.

[0096] When the heating module is in the on state, the control method further includes:

[0097] S1052: Obtain a second ozone concentration inside the air conditioner, compare the second ozone concentration with a second preset concentration threshold, and if the second ozone concentration is less than or equal to the second preset concentration threshold, turn off the heating module.

[0098] Similarly, when the fresh air module is in the on state, the control method also includes: obtaining a second ozone concentration inside the air conditioner, comparing the second ozone concentration with a second preset concentration threshold, and if the second ozone concentration is less than or equal to the second preset concentration threshold, turning off the fresh air module.

[0099] The ozone concentration inside the air conditioner can be obtained by installing a second ozone concentration sensor or other measuring equipment inside the air conditioner. The second preset concentration threshold needs to consider the potential impact of ozone on human health and the requirements of environmental standards. The specific value is obtained by the designer through multiple experimental tests. For example, the second preset concentration threshold is 0.1 mg / m 3 .

[0100] It can be understood that when the heating module and the fresh air module are controlled to be turned off, since the interior of the air conditioner is the space where the ozone generator directly acts, and the internal space of the air conditioner is relatively small and relatively closed, the ozone concentration distribution is relatively uniform. Therefore, compared with measuring the ozone concentration in the room, measuring the ozone concentration inside the air conditioner can more accurately reflect the effect of ozone being discharged to the outdoors under the action of the heating module and the fresh air module. This can more accurately control the closing time of the heating module and the fresh air module to ensure that the indoor ozone concentration is lower than the second preset concentration threshold that will not affect the health and safety of the user.

[0101] S106: Acquire the internal humidity of the air conditioner, and determine the target operating time of the ozone generator based on the internal humidity.

[0102] It should be noted that step S106 can be performed simultaneously with or after step S105.

[0103] In a high humidity environment, the activity of ozone will decrease, causing its chemical reaction rate with odor molecules to slow down. Therefore, by determining the operating time of the ozone generator according to the internal humidity of the air conditioner, the operating time of the ozone generator can be reasonably selected to ensure that enough ozone can be generated to react with odor molecules, thereby improving the deodorization effect and more effectively removing odors inside the air conditioner.

[0104] Specifically, in a high humidity environment, the reproduction rate of microorganisms such as bacteria and mold may be accelerated, and the odor substances in the air may also be more volatile. Therefore, in order to more effectively remove the odor inside the air conditioner, in general, the higher the internal humidity of the air conditioner, the longer the ozone generator runs. For details, please refer to the following Table 1:

[0105] Table 1 Relationship between the internal humidity of the air conditioner and the running time of the ozone generator Internal humidity of the air conditioner How long does the ozone generator run? <30% 10min 30%-50% 15min 50%-70% 20min >70% 30min

[0106] It should be noted that the numerical values ​​in the above examples are merely exemplary and should not be construed as limiting the scope of protection of the present invention.

[0107] S107: Obtain the user's first real-time distance from home.

[0108] For details of the specific process of obtaining the first real-time distance from home, please refer to step S1 of Example 1.

[0109] S108: Compare the first real-time distance from home with the second preset distance threshold, that is, determine whether the first real-time distance from home is greater than the second preset distance threshold.

[0110] The second preset distance threshold is smaller than the first preset distance threshold. The second preset distance threshold is closely related to the time required for the air conditioner to reduce the ozone concentration in the room to a level that will not affect the health and safety of the user after exiting the ozone deodorization mode. The second preset distance threshold is set by the designer through experimental testing and can be flexibly adjusted according to the actual needs of the user. For example, in one embodiment, the first preset distance threshold is 2 km, the second preset distance threshold is 1 km, and the third preset distance threshold is 3 km.

[0111] S1081: If the first real-time distance from home is less than or equal to (or less than) the second preset distance threshold, then execute step S109. When the user's real-time distance from home is less than or equal to the second preset distance threshold, that is, it is determined that the user is located in a neighborhood relatively close to the residence (the neighborhood is closer to the user's residence than the surrounding area), the air conditioner should immediately terminate the ozone deodorization mode (that is, directly exit the ozone deodorization mode) to ensure that the indoor ozone can be completely dissipated before the user arrives home, providing the user with a safe and fresh indoor environment.

[0112] S1082: If the first real-time distance from home is greater than (or greater than or equal to) the second preset distance threshold, execute step S110.

[0113] S109, making the air conditioner exit the ozone deodorization mode.

[0114] By exiting the ozone deodorization mode in time, the ozone generator will also stop running accordingly. At this time, the indoor ozone concentration will be greater than the first preset concentration threshold, and the air conditioner will control the heating module and / or the fresh air module to start. Under the action of the heating module and the fresh air module, the indoor ozone concentration can be continuously diluted to ensure that the indoor ozone has been fully dissipated before the user returns home, thereby effectively preventing the user from being exposed to the high concentration of ozone that may be generated during the ozone deodorization process, which is beneficial to protecting the health and safety of the user.

[0115] S110: Compare the first real-time distance from home with the first preset distance threshold, that is, determine whether the first real-time distance from home is less than or equal to the first preset distance threshold. Specifically including:

[0116] S1101. If the first real-time distance from home is less than or equal to (or less than) a first preset distance threshold, execute step S111.

[0117] S1102: If the first real-time distance from home is greater than (or greater than or equal to) the first preset distance threshold, return to step S107.

[0118] S111, continuously detecting and recording a plurality of subsequent distances at a set frequency.

[0119] Setting the frequency means recording the user's real-time distance from home at a predetermined time interval, that is, recording the user's real-time distance from home once every certain period of time. In this process, the number of records can be flexibly adjusted, such as choosing to record 3 times, 4 times or 5 times of subsequent distance data, to meet the personalized requirements of different users for monitoring needs.

[0120] S112: Predicting the user's movement trend based on multiple subsequent distances.

[0121] By comprehensively analyzing a data set consisting of multiple subsequent distance data, the changing trend of the user's distance from home can be analyzed, and the user's movement trend can be predicted based on this. For example, if the data analysis shows that the user's distance from home is gradually decreasing, the user's movement trend can be predicted to be a return home trend; otherwise, the user's movement trend is predicted to be a non-return home trend.

[0122] S113: Determine whether the user's movement trend is a return-home trend. Specifically, it includes:

[0123] S1131. If it is determined that the user's movement trend is a returning home trend, execute step S114.

[0124] S1132: If it is determined that the user's movement trend is not a trend of returning home, the air conditioner is controlled to maintain the original state and the process returns to step S107.

[0125] It should be noted that, although the previous step S1101 has determined that the first real-time distance from home is less than or equal to the first preset distance threshold, since a period of time has passed during the execution of step S111 and the user's movement trend is not a returning home trend, it means that the user's real-time distance from home is not gradually decreasing, that is, the user's real-time distance from home has undergone a large change, and it is even possible that the user's real-time distance from home exceeds the first preset distance threshold. Therefore, it is necessary to return to execute step S107 in order to re-obtain the user's first real-time distance from home for re-judgment.

[0126] In addition, when the user's path home is not a straight line (for example, a curve or a broken line), when the system conducts a comprehensive analysis of a data set consisting of multiple subsequent distance data, the data analysis shows that the user's distance change trend from home is not a gradually shrinking straight line. At this time, the air conditioner system may misjudge the user's movement trend. Therefore, after judging that the user's movement trend is not a trend of returning home, when returning to execute step S107 to obtain the user's first real-time distance from home, it is still necessary to execute step S108, that is, compare the first real-time distance from home with the second preset distance threshold to determine whether the user is in a close proximity to the residence at this time, so that when the air conditioner system makes a misjudgment, it can still promptly control the air conditioner to exit the ozone deodorization mode.

[0127] S114. Obtain the current operating time of the ozone generator.

[0128] The air conditioner is equipped with a special timing module inside, which starts timing when the ozone generator is started, so the air conditioner system can track and accurately obtain the current operating time of the ozone generator in real time.

[0129] S115: Calculate the remaining time based on the target running time and the current running time.

[0130] Since the target operating time of the ozone generator has been determined by the internal humidity of the air conditioner in the previous step S106, the remaining operating time of the ozone generator can be obtained by subtracting the current operating time from the target operating time.

[0131] S116: Compare the remaining time with a preset time threshold, that is, determine whether the remaining time is less than or equal to the preset time threshold.

[0132] The preset time threshold needs to consider allowing the ozone generator to continue operating until the remaining time is over, under the premise of not affecting the reduction of indoor ozone concentration to a level that does not affect the safety and health of users, so that the air conditioner can successfully complete the ozone deodorization process within the target operating time. The specific value of the preset time threshold is obtained by designers through testing experiments, and can also be flexibly adjusted according to the actual situation of the user.

[0133] Step S116 includes step S1161 and step S1162, which are specifically as follows:

[0134] S1161. If the remaining time is less than or equal to (or less than) the preset time threshold, execute step S117.

[0135] S1162: If the remaining time is greater than (or greater than or equal to) the preset time threshold, return to step S109. At this time, the user's movement trend is a trend of returning home and the remaining time of the ozone generator is greater than the preset time threshold. In order to give priority to reducing the indoor ozone concentration to a harmless level before the user returns home, it is necessary to exit the ozone deodorization mode in time.

[0136] S117, controlling the ozone generator to continue running for the remaining time.

[0137] When the remaining time of the ozone generator does not exceed the preset time threshold, the ozone generator can be allowed to continue operating until the remaining time is over, and then the air conditioner will automatically exit the ozone deodorization mode. Finally, the heating module and the fresh air module will continuously dilute and reduce the indoor ozone concentration to ensure that the indoor ozone has been fully dissipated before the user returns home, thereby effectively preventing the user from being exposed to high concentrations of ozone that may be produced during the ozone deodorization process, which is beneficial to protecting the health and safety of the user.

[0138] In this embodiment, before starting the ozone generator, it is necessary to consider not only the environmental conditions when the user is not indoors, but also whether the user's real-time distance from home exceeds a third preset distance threshold, that is, whether the user can return home quickly. This can reserve enough time for the air conditioner system to flexibly judge and decide whether to interrupt the ozone deodorization mode, thereby ensuring the safety and rationality of the operation.

[0139] After the ozone generator is started, the system will continue to monitor the user's real-time distance from home to assess whether the user is in the immediate vicinity or surrounding area of ​​the residence (specifically determined by comparing the first preset distance and the second preset distance). If the user is in the immediate vicinity of the residence, the system will immediately instruct the air conditioner to exit the ozone deodorization mode to ensure that the indoor ozone concentration has dropped to a safe level before the user arrives home, effectively preventing the user from being exposed to a high-concentration ozone environment with potential risks, thereby effectively protecting the user's health and safety.

[0140] If the user is in the vicinity of the residence, the system will further collect multiple subsequent distance data of the user to predict their movement trends, and will also compare the remaining time of the ozone generator with the preset time threshold. Based on the user's movement trend, the area they are in, and the comparison of the remaining time with the preset threshold, the system will make a decision: whether to immediately exit the ozone deodorization mode of the air conditioner, or allow the ozone generator to continue running until the remaining time is over. This can effectively balance the safe reduction of indoor ozone concentration with the satisfaction of user needs, ensuring that the air conditioner can complete the established ozone deodorization process without posing a threat to the user's health.
