Description

Technical Field

[0001] The embodiments of the present invention relate to the field of air conditioning, and in particular to a method, device, electronic device and storage medium for self-cleaning of a fresh air air conditioner. Background Art

[0002] With the improvement of living quality, basic cooling and heating can no longer meet people's pursuit of air conditioning functions. Ordinary air conditioners need to close doors and windows when turning on, resulting in poor air circulation and affecting indoor air quality. In order to meet the needs of consumers, a new type of fresh air air conditioner has appeared on the market. The fresh air air conditioner uses a centrifugal fan to achieve circulation and ventilation between room air and outdoor air, and has the function of purifying the air.

[0003] However, in actual use, after turning on the fresh air function for a period of time, dust, lint, etc. in the air are likely to clog the filter during the ventilation process, affecting the indoor air exchange effect. Summary of the invention

[0004] The purpose of the present invention is to at least provide a method, device, electronic device and storage medium for self-cleaning of a fresh air air conditioner, which can at least solve the technical problem that the filter is easily clogged by dust, lint, etc. after using the fresh air function for a period of time, and at least can clean the accumulated dust and lint and alleviate the problem of filter clogging.

[0005] In order to solve the above technical problems, at least one embodiment of the present application provides a method for self-cleaning a fresh air air conditioner, comprising:

[0006] When the fresh air function is not activated, detect whether there is anyone in the target space;

[0007] When the test result meets any of the following conditions, the fan will be started to reverse according to the preset working hours for self-cleaning:

[0008] When there is no one in the target space, and the fresh air function is turned on for a preset time period within a preset time period; and

[0009] When there is someone in the target space and the decibel value in the target space is less than a preset decibel threshold.

[0010] At least one embodiment of the present application further provides a fresh air air conditioner self-cleaning device, comprising:

[0011] The human body detection module is used to detect whether there is anyone in the target space when the fresh air function is not activated;

[0012] The reversal control module is used to start the fan reverse rotation according to the preset working hours for self-cleaning when the detection result meets any of the following conditions:

[0013] When there is no one in the target space, and the fresh air function is turned on for a preset time period within a preset time period; and

[0014] When there is someone in the target space and the decibel value in the target space is less than a preset decibel threshold.

[0015] At least one embodiment of the present application also provides an electronic device, comprising: at least one processor; and a memory communicatively connected to the at least one processor; wherein the memory stores instructions executable by the at least one processor, and the instructions are executed by the at least one processor so that the at least one processor can execute the above-mentioned fresh air air conditioner self-cleaning method.

[0016] At least one embodiment of the present application further provides a computer-readable storage medium storing a computer program, which implements the above-mentioned fresh air air conditioner self-cleaning method when executed by a processor.

[0017] The embodiments of the present application provide a method, device, electronic device and storage medium for self-cleaning of a fresh air air conditioner. When it is detected that there is no one in the target space, if the fresh air function has been running for a certain period of time within a preset time period, the fan is automatically started to reverse and perform self-cleaning. This method avoids the discomfort that may be caused by using the cleaning function when there are people, and also ensures that the air conditioner can clean up the accumulated dust and dirt in time after long-term use, maintains its efficient operation, and realizes automatic cleaning only when necessary, avoiding unnecessary energy waste. When there are people in the target space but the decibel value is lower than the preset threshold, self-cleaning is also started, indicating that the system not only takes into account the presence of people, but also further considers the activity status of people. Starting cleaning when the decibel value is low can reduce interference to users and help improve the overall comfort and satisfaction of users.

[0018] In some optional embodiments, when no one is in the target space and the fresh air function is turned on for a preset time period within a preset time period, the fan is started to reverse according to the preset working hours to perform self-cleaning, including:

[0019] When there is no one in the target space and the fresh air function is turned on for a preset time period, the reverse power of the fan is determined according to the time period when the fresh air function is turned on;

[0020] According to the preset working hours, the fan is controlled to reverse based on the reverse power.

[0021] In this embodiment, the reverse power of the fan is determined according to the duration of the fresh air function being turned on, so that the strength during the cleaning process can be controlled more accurately. Adjusting the reverse power according to actual needs can avoid unnecessary energy consumption. If a fixed reverse power is used for cleaning, energy may be wasted, especially when the fresh air function is turned on for a short time and less dust is accumulated. By dynamically adjusting the reverse power, more efficient energy utilization can be achieved.

[0022] In some optional embodiments, in determining the reverse power of the fan according to the duration for which the fresh air function is turned on, there is a positive proportional relationship between the magnitude of the reverse power and the duration for which the fresh air function is turned on.

[0023] In this embodiment, since the reverse power is proportional to the length of time the fresh air function is turned on, when the fresh air function is running for a long time, more dust and dirt may be accumulated. At this time, the system increases the reverse power to ensure more thorough cleaning. This dynamic adjustment helps to achieve the expected cleaning effect in different situations.

[0024] In some optional embodiments, when there is someone in the target space and the decibel value in the target space is less than a preset decibel threshold, the fan is started to reverse according to the preset working hours to perform self-cleaning, including:

[0025] When there is someone in the target space and the decibel value in the target space is less than a preset decibel threshold, the fan is controlled to reverse at a preset minimum power according to preset working hours.

[0026] In this embodiment, in an environment with a low decibel value, people usually expect to maintain a relatively quiet atmosphere. At this time, if the fan is started at a higher power to reverse for cleaning, it may generate obvious noise and break the original tranquility. However, running at the minimum power can significantly reduce the noise generation, avoid unnecessary interference to users, and keep the indoor environment quiet and comfortable.

[0027] In some optional embodiments, after starting the fan reverse rotation according to the preset working hours, the method further includes:

[0028] Check whether the cleanliness meets the preset standards;

[0029] When the cleanliness does not reach the preset standard, adjusting the reverse power of the fan according to the detection result of whether there is anyone in the target space;

[0030] Repeat according to the preset working hours, start the fan reverse rotation with the adjusted reverse power to perform self-cleaning, until the cleanliness reaches the preset standard.

[0031] In this embodiment, by detecting whether the cleanliness reaches the preset standard, each self-cleaning process can achieve the expected cleaning effect. If the cleanliness does not meet the standard, the system will adjust the reverse power according to the current situation and continue cleaning until the requirements are met. According to whether there are people in the target space and the cleanliness detection results, the reverse power of the fan is intelligently adjusted, which not only helps to improve cleaning efficiency, but also provides users with a more comfortable use experience.

[0032] In some optional embodiments, adjusting the reverse power of the fan according to the detection result of whether there is a person in the current target space includes:

[0033] If the detection result is that there is someone in the target space, detecting whether the decibel value in the current target space is greater than or equal to the decibel threshold;

[0034] When the decibel value in the current target space is greater than or equal to the decibel threshold, reducing the reverse power of the fan to a preset minimum power;

[0035] When the decibel value in the current target space is less than the decibel threshold, the current reverse power of the fan is maintained.

[0036] In this embodiment, when there are people in the target space and the decibel value is high, reducing the fan reverse power to the preset minimum power can significantly reduce the noise generation and avoid unnecessary interference to the user. When the decibel value is small, maintaining the current reverse power can maintain a good cleaning ability without generating additional noise. The fan reverse power is flexibly adjusted according to the actual situation in the target space (whether there are people and the decibel value), so that a good cleaning effect can be achieved in different environments while minimizing the impact on the user.

[0037] In some optional embodiments, adjusting the reverse power of the fan according to the detection result of whether there is a person in the current target space includes:

[0038] If the detection result shows that there is no one in the target space, the reverse power of the fan is increased.

[0039] In this embodiment, if there is no one in the target space, there is no need to consider the impact of noise. At this time, increasing the reverse power of the fan can more effectively remove dust, dirt and other impurities inside the air conditioner.

[0040] In some optional embodiments, it is characterized in that it also includes:

[0041] When there is someone in the target space and the decibel value in the target space is greater than or equal to the decibel threshold, the self-cleaning function is not started.

[0042] In this embodiment, in the space where people are active, when the decibel value reaches or exceeds a certain threshold, it usually means that the ambient noise is already relatively high. At this time, if the self-cleaning function is activated, the additional noise generated by the fan reversal may cause further interference to the user and affect their comfort. Therefore, not activating the self-cleaning function can avoid adding unnecessary noise and keep the indoor environment quiet. BRIEF DESCRIPTION OF THE DRAWINGS

[0050] To make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the embodiments of the present application will be described in detail below in conjunction with the accompanying drawings. However, it will be appreciated by those skilled in the art that in the present application, many technical details are proposed in order to enable the reader to better understand the present application. However, even without these technical details and various changes and modifications based on the following embodiments, the technical scheme claimed in the present application can also be implemented. The division of the following embodiments is for the convenience of description, and the specific implementation of the present application should not be construed as any limitation, and the various embodiments can be combined and referenced with each other under the premise of no contradiction.

[0051] As an important part of modern home life, the performance and user experience of fresh air air conditioners are directly related to the comfort and health level of residents. However, as the use time increases, dust, lint and other impurities are easily accumulated inside the air conditioner, clogging the filter, which not only affects the operating efficiency of the air conditioner, but also may have a negative impact on the indoor air quality.

[0052] In order to solve the above-mentioned technical problem that the filter is easily clogged with dust, lint, etc. after using the fresh air function for a period of time, the present invention proposes a self-cleaning method for a fresh air air conditioner. The implementation details of the self-cleaning method for the fresh air air conditioner of this embodiment are described in detail below. The following content is only the implementation details provided for the convenience of understanding and is not necessary for the implementation of this solution.

[0053] Embodiment 1:

[0054] The method for self-cleaning the fresh air air conditioner of this embodiment can be applied to electronic devices with communication, computing and data storage capabilities. The specific process can be as follows: Figure 1 As shown, including:

[0055] Step 110, when the fresh air function is not activated, detecting whether there is anyone in the target space;

[0056] Step 120, when the detection result meets any of the following conditions, the fan is started to reverse according to the preset working hours to perform self-cleaning:

[0057] When there is no one in the target space, and the fresh air function is turned on for a preset time period within a preset time period; and

[0058] When there is someone in the target space and the decibel value in the target space is less than a preset decibel threshold.

[0059] In this embodiment, it is determined whether there are people in the target space, so that the impact of noise on the user can be considered when there are people, and there is no need to worry when there are no people. Specifically, infrared sensors, cameras, or human motion sensors can be used to monitor the activities of people in the target space in real time. When the sensor detects human activity, the system records the current state as "someone"; when the sensor does not detect human activity within a certain period of time, the system records the current state as "no one".

[0060] Step 120 provides two detection conditions for starting the self-cleaning function:

[0061] Condition 1: When no one is in the target space, and the fresh air function is turned on for a preset time period. When condition 1 is met, it indicates that the fresh air function has been used for too long, and the self-cleaning function needs to be activated to remove accumulated dust and dirt.

[0062] In actual use, users can set the preset time period and preset duration of the self-cleaning function through the air conditioner control panel or mobile phone APP. The preset time period can be set to one week, one month or three months, and the preset duration can be set to 2 hours, 4 hours, etc. For example, if the preset time period is set to one month and the preset duration is 10 hours, when the air conditioner turns on the fresh air function for 10 hours within a month, it means that a lot of dust and dirt may have accumulated at this time, and self-cleaning is required.

[0063] The preset time period and duration can be set according to the user's usage habits and actual needs to ensure the rationality and effectiveness of the self-cleaning function. It can also be customized by the user on the App according to his or her own usage habits.

[0064] In some optional embodiments, before starting the self-cleaning function, the system notifies the user in advance (such as through APP push messages, air conditioning panel display, etc.) so that the user understands the upcoming operations.

[0065] Condition 2: When there is someone in the target space, and the decibel value in the target space is less than a preset decibel threshold.

[0066] The purpose of setting condition 2 is to start the self-cleaning function to remove accumulated dust and dirt when there are people in the target space but the ambient noise is low, while avoiding noise interference to users. The specific implementation method is as follows:

[0067] 1) Set the preset decibel threshold:

[0068] Users can set the preset decibel threshold (such as 40 decibels, 50 decibels, etc.) of the self-cleaning function through the air-conditioning control panel or mobile phone APP.

[0069] 2) Detect environmental noise level:

[0070] The system monitors the ambient noise level in the target space in real time through built-in noise sensors or microphones and other devices.

[0071] 3) Determine whether the conditions are met:

[0072] When the system detects that there are people in the target space and the ambient noise level is lower than the preset decibel threshold, the system determines that the conditions are met and starts the self-cleaning function. The system starts the fan reverse rotation for self-cleaning according to the preset working hours (such as 10 minutes, 20 minutes, etc.). At the same time, the system controls the power and speed of the fan reverse rotation to ensure that the noise generated during the cleaning process does not exceed the preset decibel threshold.

[0073] The following are examples of actual application scenarios:

[0074] Example 1:

[0075] The user sets the preset time period of the self-cleaning function to 2:00 a.m. to 4:00 a.m. every day, and the preset duration is that the fresh air function is turned on for 4 hours continuously. At 3:00 a.m. on a certain day, the system detected that there was no one in the target space, and the fresh air function had been turned on for 4 hours continuously from 0:00 a.m. to 3:00 a.m. on the same day. The system judged that the conditions were met, so it started the fan reverse at 3:10 a.m. for self-cleaning, which lasted for 20 minutes. During the self-cleaning process, the system pushed a notification message to the user through the APP, informing the user that the self-cleaning function has been activated.

[0076] Example 2:

[0077] The user sets the preset decibel threshold of the self-cleaning function to 50 decibels. At 3 p.m. on a certain day, the system detects that there are people in the target space, but the ambient noise level is only 38 decibels. The system determines that the conditions are met, so it starts the fan reverse at 3:15 p.m. for self-cleaning, which lasts for 15 minutes.

[0078] In summary, the fresh air air conditioner self-cleaning method provided in this embodiment detects the personnel situation and environmental noise level in the target space, and automatically starts the fan reverse for self-cleaning in combination with the use of the fresh air function. When it is detected that there is no one in the target space, if the fresh air function has been running for a certain period of time within a preset time period, the fan reverse is automatically started for self-cleaning. This method avoids the discomfort that may be caused by using the cleaning function when there are people, and also ensures that the air conditioner can clean up the accumulated dust and dirt in time after long-term use, maintain its efficient operation, and realize automatic cleaning only when necessary, avoiding unnecessary energy waste. When there are people in the target space but the decibel value is lower than the preset threshold, self-cleaning is also started, indicating that the system not only considers the presence of people, but also further considers the activity status of people. Starting cleaning when the decibel value is low can reduce interference to users and help improve the overall comfort and satisfaction of users.

[0079] In some optional embodiments, when there is no one in the target space and the duration of the fresh air function being turned on reaches a preset time within a preset time period, the fan is started to reverse according to the preset working hours to perform self-cleaning, including: when there is no one in the target space and the duration of the fresh air function being turned on reaches a preset time within a preset time period, the reversal power of the fan is determined according to the duration of the fresh air function being turned on; and the fan is controlled to reverse based on the reversal power according to the preset working hours.

[0080] Usually, within a preset time period, the cumulative length of time that users use the fresh air function is different, and correspondingly, the degree of accumulation of impurities such as dust is also different. The longer the cumulative use time of the fresh air function, the greater the possibility of accumulating more impurities. Therefore, determining the reverse power of the fan according to the length of time the fresh air function is turned on can more accurately control the intensity of the cleaning process. Adjusting the reverse power according to actual needs can avoid unnecessary energy consumption. If a fixed reverse power is used for cleaning, energy may be wasted, especially when the fresh air function is turned on for a short time and less dust is accumulated. By dynamically adjusting the reverse power, more efficient energy utilization can be achieved.

[0081] In some optional embodiments, in determining the reverse power of the fan according to the duration for which the fresh air function is turned on, there is a positive proportional relationship between the magnitude of the reverse power and the duration for which the fresh air function is turned on.

[0082] In this embodiment, the reverse power of the fan is set to different gears, for example, set to the following three gears:

[0083]

[0084] Correspondingly, the duration of the fresh air function is also divided into three levels, for example:

[0085] Level 1: The fresh air function is turned on for less than 30 minutes within the preset time period;

[0086] Level 2: The fresh air function is turned on for more than 30 minutes and less than 1 hour within the preset time period;

[0087] Level 3: The fresh air function is turned on for more than 1 hour during the preset time period.

[0088] When the fresh air function is turned on for less than 30 minutes within the preset time period, the fan is controlled to reverse at the first power level; when the fresh air function is turned on for more than 30 minutes but less than 1 hour within the preset time period, the fan is controlled to reverse at the second power level; when the fresh air function is turned on for more than 1 hour within the preset time period, the fan is controlled to reverse at the third power level.

[0089] In this embodiment, since the reverse power is proportional to the length of time the fresh air function is turned on, when the fresh air function is running for a long time, more dust and dirt may be accumulated. At this time, the system increases the reverse power to ensure more thorough cleaning. This dynamic adjustment helps to achieve the expected cleaning effect in different situations.

[0090] In some optional embodiments, the fan can also be controlled to reverse alternately at different powers. For example, if the fresh air function is turned on for more than 1 hour within a preset time period, and the preset working hours are 15 minutes, the fan is first controlled to reverse at the third power level for 10 minutes, and then the fan is controlled to reverse at the second power level for 5 minutes. Through the method of this embodiment, the energy-saving effect and control flexibility are further improved.

[0091] In some optional embodiments, the preset working hours are based on the duration of the fresh air function being turned on within a preset time period. For example, if the duration of the fresh air function being turned on within the preset time period is less than 30 minutes, the preset working hours are 10 minutes; if the duration of the fresh air function being turned on within the preset time period is greater than 30 minutes but less than 1 hour, the corresponding preset working hours are 20 minutes; if the duration of the fresh air function being turned on within the preset time period is greater than 1 hour, the corresponding preset working hours are 30 minutes. In this embodiment, the time for the fan to reverse is set in direct proportion to the duration of the fresh air function being turned on, which can more finely control the self-cleaning effect and help save energy and reduce emissions.

[0092] In some optional embodiments, when there is someone in the target space and the decibel value in the target space is less than a preset decibel threshold, the fan is started to reverse according to the preset working hours for self-cleaning, including: when there is someone in the target space and the decibel value in the target space is less than a preset decibel threshold, the fan is controlled to reverse according to the preset working hours and at a preset minimum power.

[0093] Specifically, according to the different power gears set in the above embodiments, when the decibel value in the target space is less than the preset decibel threshold, the fan is controlled to reverse according to the first gear power.

[0094] In this embodiment, in an environment with a low decibel value, people usually expect to maintain a relatively quiet atmosphere. At this time, if the fan is started at a higher power to reverse for cleaning, it may generate obvious noise and break the original tranquility. However, running at the minimum power can significantly reduce the noise generation, avoid unnecessary interference to users, and keep the indoor environment quiet and comfortable.

[0095] In some optional embodiments, after starting the fan reverse according to the preset working hours, it also includes: detecting whether the cleanliness reaches the preset standard; when the cleanliness does not reach the preset standard, adjusting the reversal power of the fan according to the detection result of whether there is someone in the target space; repeating the preset working hours, starting the fan reverse with the adjusted reversal power for self-cleaning, until the cleanliness reaches the preset standard.

[0096] In this embodiment, a cleanliness detection and power adjustment mechanism is further introduced. The core of this mechanism is that when the fan reverses to start self-cleaning, the system will detect whether the current cleanliness meets the preset standard. If it does not meet the standard, the system will dynamically adjust the fan's reverse power according to whether there are people in the target space, and start the cleaning process again until the cleanliness meets the requirements. The specific implementation process is shown in the example below:

[0097] Example 1: Deep cleaning in an unmanned environment

[0098] Initial settings: The user sets the preset time period for the self-cleaning function to 10 pm to 2 am, and the preset cleanliness standard to 90% (cleanliness is a quantitative indicator ranging from 0% to 100%, where 100% means complete cleaning, and cleanliness can be confirmed by visual inspection).

[0099] First cleaning start: At 10 o'clock in the evening, the system detects that there is no one in the target space and the usage time of the fresh air function has reached the preset conditions, so it starts the fan reverse rotation for self-cleaning according to the preset working hours (such as 15 minutes).

[0100] Cleanliness detection: After the first cleaning, the system detected a cleanliness level of 85%, which did not meet the preset standard of 90%.

[0101] Power adjustment and repeated cleaning: Since there is no one in the target space, the noise effect does not need to be considered. The system increases the reverse power of the fan (for example, from the original second gear power to the third gear power) and starts the cleaning process again for 15 minutes.

[0102] Re-test and end: After the second cleaning, the system detects that the cleanliness has reached 92%, meeting the preset standard, so the cleaning process is stopped.

[0103] Example 2: Low-noise cleaning in a human environment

[0104] Initial settings: The user sets the preset decibel threshold of the self-cleaning function to 50 decibels and the preset cleanliness standard to 85%.

[0105] First cleaning start: At 3 pm, the system detects that there are people in the target space, but the ambient noise level is less than 50 decibels, so the fan is started to reverse and perform self-cleaning at a lower reverse power (such as the first gear power) according to the preset working hours (such as 10 minutes).

[0106] Cleanliness detection: After the first cleaning, the system detected a cleanliness level of 80%, which did not meet the preset standard of 85%.

[0107] Power adjustment and repeated cleaning: Since there are people in the target space, the system will not increase the fan's reverse power to increase additional noise, but will choose to continue to maintain the last power level or reduce the power level and start the cleaning process again for 10 minutes. At the same time, the system will continue to monitor the ambient noise level to ensure that it does not exceed the preset threshold.

[0108] Multiple repetitions and final inspection: If the cleanliness level is still not up to standard, the system may continue to perform multiple repetitions at fine-tuned power until the cleanliness level meets the requirements.

[0109] In this embodiment, by detecting whether the cleanliness reaches the preset standard, each self-cleaning process can achieve the expected cleaning effect. If the cleanliness does not meet the standard, the system will adjust the reverse power according to the current situation and continue cleaning until the requirements are met. According to whether there are people in the target space and the cleanliness detection results, the reverse power of the fan is intelligently adjusted, which not only helps to improve cleaning efficiency, but also provides users with a more comfortable use experience.

[0110] In some optional embodiments, the reverse power of the fan is adjusted according to the detection result of whether there is someone in the target space, including: if the detection result is that there is someone in the target space, detecting whether the decibel value in the target space is greater than or equal to the decibel threshold; when the decibel value in the target space is greater than or equal to the decibel threshold, reducing the reverse power of the fan to a preset minimum power; when the decibel value in the target space is less than the decibel threshold, maintaining the current reverse power of the fan.

[0111] In actual use, it may happen that when self-cleaning is started for the first time, there is no one in the target space, so a higher power level (such as the third power level in the above embodiment) is set for reversal. When the cleanliness is not up to standard and a new round of self-cleaning is required, there are people in the target space and they are doing some daily activities. In this scenario, if the reversal continues according to the original third power level, it will obviously cause too much noise and affect the normal activities of the user. Therefore, the method of this embodiment fully considers this impact and achieves a better balance between cleaning effect and noise impact:

[0112] If the current decibel value is greater than or equal to the decibel threshold, it means that the ambient noise is already high. In order to avoid further increase in noise, the system will reduce the fan's reverse power to the preset minimum power to minimize the noise level while maintaining a certain cleaning effect;

[0113] If the current decibel value is less than the decibel threshold, it means that the ambient noise is still within an acceptable range, and the system will maintain the current reverse power of the fan to continue effective cleaning.

[0114] In this embodiment, when there are people in the target space and the decibel value is high, reducing the fan reverse power to the preset minimum power can significantly reduce the noise generation and avoid unnecessary interference to the user. When the decibel value is small, maintaining the current reverse power can maintain a good cleaning ability without generating additional noise. The fan reverse power is flexibly adjusted according to the actual situation in the target space (whether there are people and the decibel value), so that a good cleaning effect can be achieved in different environments while minimizing the impact on the user.

[0115] In some optional embodiments, the reverse power of the fan is adjusted according to the detection result of whether there is anyone in the target space, including: if the detection result is that there is no one in the target space, the reverse power of the fan is increased. In this embodiment, if there is no one in the target space, the impact of noise does not need to be considered. At this time, increasing the reverse power of the fan can more effectively remove dust, dirt and other impurities inside the air conditioner. For example, the second power level is adjusted to the third power level to achieve faster removal of impurities.

[0116] In some optional embodiments, it is characterized in that it also includes: when there is someone in the target space and the decibel value in the target space is greater than or equal to the decibel threshold, the self-cleaning function is not started.

[0117] In this embodiment, in the space where people are active, when the decibel value reaches or exceeds a certain threshold, it usually means that the ambient noise is already relatively high. At this time, if the self-cleaning function is activated, the additional noise generated by the fan reversal may cause further interference to the user and affect their comfort. Therefore, not activating the self-cleaning function can avoid adding unnecessary noise and keep the indoor environment quiet.

[0118] Embodiment 2:

[0119] Based on the above embodiments, this embodiment provides an application example. This embodiment provides a fresh air joint self-cleaning device, which applies the fresh air air conditioner self-cleaning method described in the above embodiments.

[0120] like Figure 6 As shown, the fresh air connector self-cleaning device includes a light source, a camera, a volume acquisition module, an infrared sensor module, a control module, a fan 610, an exhaust pipe, a fresh air connector 620, etc. Among them, the fresh air connector is installed indoors and embedded in the wall. The exhaust pipe extends from the wall to the outer wall, connecting the fresh air connector and the fresh air fan installed on the outdoor wall to transport turbid air indoors. The light source and camera are installed on the inside of the fresh air connector, and the volume sensor module and the infrared sensor module are integrated in the air conditioner hanging unit.

[0121] In the self-cleaning mode, the fan startup power setting is divided into three levels: first level power, second level power, and third level power:

[0122]

[0123] The specific self-cleaning control process is as follows:

[0124] Working condition 1: When the fresh air function is not turned on, the infrared sensor module senses the situation in the room, detects whether there is anyone in the room and feeds back to the control module. If it is detected that there is no one in the room, and the fresh air function is turned on for less than 30 minutes within the preset time period, the fresh air system starts the self-cleaning mode, and the control module sends a signal through the Bluetooth module to control the fan to reverse at the first power level to generate negative pressure, clean the dust particles attached to the fresh air connector filter, and perform cleaning according to the preset working hours of the timer.

[0125] Working condition 2: If it is detected that there is no one in the room and the fresh air function is turned on within the preset time period of 30 minutes to 1 hour, the fan will be controlled to start at the second power level.

[0126] Working condition three: If it is detected that there is no one in the room and the fresh air function is turned on for more than 1 hour within the preset time period, the fan will be controlled to start at the third power level.

[0127] like Figure 2 As shown, it is the specific control flow chart of working condition one to working condition three.

[0128] Working condition 4: If someone is detected in the room, the volume acquisition module obtains the ambient volume in the room and detects whether the volume in the room exceeds 50dB. If the volume exceeds 50dB, the self-cleaning mode will not be turned on. In self-cleaning mode, the fan reverses and starts at a higher speed. The high-speed rotating fan blades will generate more air turbulence and greater vibration, causing some noise. Studies have shown that when the ambient volume exceeds 50dB, it will affect people's normal sleep and rest. In order not to affect the user experience, when the ambient volume is slightly loud, the self-cleaning function will not be started to keep the room relatively quiet.

[0129] Working condition 5: If someone is detected in the room, the volume acquisition module obtains the ambient volume in the room and detects whether the volume in the room exceeds 50dB. If the volume does not reach 50dB, the fan is controlled to start at the first power level.

[0130] like Figure 3 As shown, it is the specific control flow chart of working condition four and working condition five.

[0131] Working condition 6: After the preset working hours are reached, the light source is turned on and the dust particles on the filter are captured by the camera. The dust information obtained is fed back to the control module, and the control module automatically determines the degree of dust cleaning based on the feedback information. If the cleaning degree reaches the preset value, the control module outputs a signal, turns off the self-cleaning mode, and stops the fan. If the cleaning degree does not meet the standard, the next step of the instruction is executed in combination with the signals fed back by the infrared sensor module and the volume acquisition module.

[0132] Working condition seven: If the cleaning level is not up to standard and it is detected that there is no one in the room, the fan power will be increased by one gear (such as the first gear is increased to the second gear, and the second gear is increased to the third gear) to improve the cleaning efficiency.

[0133] Working condition eight: If the cleanliness level is not up to standard and someone is detected in the room, determine whether the volume in the room exceeds 50dB. If the volume exceeds 50dB, reduce the fan power to the first gear (if it is in the first gear, it cannot be reduced and keeps running).

[0134] Working condition nine: If the cleanliness level does not meet the standard and someone is detected in the room, when the volume does not reach 50dB, the fan will continue to run at the original gear.

[0135] like Figure 4 As shown, this is the specific control flow chart of working conditions six to nine.

[0136] In summary, this embodiment solves at least the following technical problems:

[0137] 1. It solves the problem that after the fresh air air conditioner turns on the fresh air function, lint and dust clog the filter, causing the air circulation effect in the room to deteriorate, affecting the user experience;

[0138] 2. The fresh air connector panel is fixed by screws, and the installation position is high and difficult to access. It needs to be disassembled and cleaned with the help of tools such as ladders and screwdrivers, which is inconvenient to clean. The present invention can effectively solve this pain point.

[0139] And achieved at least the following beneficial effects:

[0140] 1. Effectively improve the ventilation efficiency of fresh air air conditioning, and improve the air quality in the room;

[0141] 2. It reduces unnecessary manual labor and cleaning costs, makes fresh air air conditioning more intelligent and convenient, and improves customers' overall satisfaction with the product.
