Abstract
Description
Technical Field
[0001] This application relates to the field of air conditioner control technology, and more specifically, to an air conditioner odor control method, device, computer-readable storage medium, and air conditioner. Background Technology
[0002] Unpleasant odors in household air conditioners are a problem across the entire industry. The sources of these odors are complex, and this issue exists for all brands, both domestic and international, with no definitive solution yet. The causes of these odors are currently inconclusive in both academia and industry, but the prevailing view is that the phenomenon is strongly correlated with odors from hydrophilic aluminum foil coatings, the adsorption of environmental odors, and microbial odors.
[0003] Existing technology discloses a method for controlling air conditioner odor, an air conditioner and its control device, and a storage medium. The method includes: acquiring the indoor water vapor dew point temperature T0, acquiring the indoor heat exchanger temperature T1, and determining whether the temperature determination condition T1 < (T0 - A) is met, where A is a preset temperature data; based on the met temperature determination condition, controlling the air conditioner to operate in a set working mode, at which time a liquid film continuously forms on the indoor heat exchanger. When the temperature determination condition is met, controlling the air conditioner to operate in a set working mode results in the continuous formation of a liquid film on the indoor heat exchanger. This liquid film covers the acidic VOCs (volatile organic compounds) concentrated in the indoor heat exchanger. The liquid film not only effectively masks the odor emitted by the acidic VOCs concentrated in the indoor heat exchanger but also slowly washes away the VOCs concentrated on the indoor heat exchanger, keeping the odor emitted from the air conditioner within the human odor threshold. This solution eliminates the need for alcohol or other alkaline cleaning agents and effectively solves the problem of significant odor emitted from the air conditioner. However, the air conditioner heat exchanger cannot maintain a liquid film indefinitely. When the indoor temperature reaches the preset value, the compressor frequency will decrease, the internal pipe temperature will increase, exceeding the air dew point, and may even reach the temperature point and shut down. After shutting down, the water film disappears, making it very easy to blow out an odor.
[0004] Therefore, how to prevent air conditioners from producing odors is a problem that urgently needs to be solved. Summary of the Invention
[0005] The main objective of this application is to provide an odor control method, apparatus, computer-readable storage medium, and air conditioner for air conditioners, so as to at least solve the problem of air conditioners easily generating odors in the prior art.
[0006] To achieve the above objectives, according to one aspect of this application, an odor control method for an air conditioner is provided, comprising: when the air conditioner is turned on, controlling the air conditioner to a first operating condition, wherein the first operating condition indicates that the air guide vane of the air conditioner is at its minimum angle and the fan is at its lowest setting; after the air conditioner operates according to the first operating condition for a preset time period, acquiring the indoor ambient temperature; when the indoor ambient temperature reaches the user-set temperature, reducing the compressor frequency and increasing the rate of decrease of the compressor frequency, so that the internal pipe temperature of the air conditioner is lower than a preset temperature, wherein the lower the compressor frequency, the higher the internal pipe temperature.
[0007] Optionally, increasing the rate of decrease of the compressor frequency to make the internal pipe temperature of the air conditioner lower than a preset temperature includes: obtaining the current compressor frequency; if the current compressor frequency is less than a preset threshold, continuing to reduce the current compressor frequency to the preset threshold and increasing the rate of decrease of the compressor frequency to make the internal pipe temperature of the air conditioner lower than the preset temperature.
[0008] Optionally, after reducing the current compressor frequency to the preset threshold, the method further includes: using a PID control algorithm to control the compressor frequency to stabilize at the preset threshold.

[0011] Optionally, when the indoor ambient temperature reaches the user-set temperature, the method further includes: controlling the air guide plate of the air conditioner to a user-set angle.
[0012] Optionally, the method further includes: increasing the pre-cooling time of the evaporator or increasing the refrigerant flow rate of the evaporator when the inner pipe temperature is higher than the preset temperature. According to another aspect of this application, an odor control device for an air conditioner is provided, comprising: a first control unit, configured to control the air conditioner to a first operating condition when the air conditioner is turned on, wherein the first operating condition indicates that the air guide vane of the air conditioner is at its minimum angle and the fan is at its lowest setting; and a reduction unit, configured to acquire the indoor ambient temperature after the air conditioner has operated according to the first operating condition for a preset period of time, and, when the indoor ambient temperature reaches the user-set temperature, reduce the compressor frequency and increase the rate of decrease of the compressor frequency, so that the inner pipe temperature of the air conditioner is lower than the preset temperature, wherein the lower the compressor frequency, the higher the inner pipe temperature.
[0013] According to another aspect of this application, a computer-readable storage medium is provided, the computer-readable storage medium including a stored program, wherein, when the program is executed, it controls the device where the computer-readable storage medium is located to perform any of the odor control methods of the air conditioner described above.

[0015] Applying the technical solution of this application, when the air conditioner is turned on, it is controlled under the first operating condition, where the air guide vane is at its minimum angle and the fan is at its lowest setting. After the air conditioner operates according to the first operating condition for a preset period of time, the indoor ambient temperature is acquired.

[0023] For ease of description, the following explains some of the nouns or terms used in the embodiments of this application:
[0024] The internal pipe temperature of an air conditioner refers to the temperature of the refrigerant pipes inside the air conditioner's indoor unit.
[0025] As described in the background section, air conditioners in the prior art are prone to producing odors. In order to solve the problem of air conditioners producing odors, embodiments of this application provide an odor control method, device, computer-readable storage medium, and air conditioner.
[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
[0027] This embodiment provides an odor control method for an air conditioner that runs on a mobile terminal, computer terminal, or similar computing device. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Also, although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in a different order than that shown here.
[0028] Figure 1 This is a flowchart of an air conditioner odor control method according to an embodiment of this application. Figure 1 As shown, the method includes the following steps:
[0029] Step S201: When the air conditioner is turned on, control the air conditioner to the first operating condition, wherein the first operating condition means that the air guide plate of the air conditioner is at its minimum angle and the fan is at its lowest speed.
[0030] Specifically, this embodiment prevents odor problems from arising in air conditioners at various stages, including when the air conditioner is turned on and during operation. The minimum angle of the air guide vane typically refers to the vane being positioned at its lowest or lowest point. When the air conditioner is turned on, the control circuit adjusts the air guide vane drive motor, moving the vane to the lowest point of its mechanical travel or a preset minimum angle position. This operation ensures that the airflow from the air conditioner outlet is directed away from the user, especially avoiding direct airflow towards the user's nose, thus reducing the amount of odor substances that may accumulate on the evaporator surface during initial startup from being directly introduced into the breathing area. Simultaneously, during the pre-cooling phase of air conditioner startup, the fan is set to its lowest operating speed. This typically means reducing the fan motor speed and airflow, slowing the airflow speed over the evaporator surface. Low airflow helps the evaporator surface temperature drop evenly, preventing odor problems caused by rapid drying. At the same time, lower airflow also reduces the rapid diffusion of odor substances on the evaporator surface, further reducing the odor perceived by the user.
[0031] Step S202: After the air conditioner has been running for a preset period of time according to the first operating conditions, the indoor ambient temperature is obtained. When the indoor ambient temperature reaches the user-set temperature, the compressor frequency is reduced and the rate of decrease of the compressor frequency is increased, so that the temperature of the inner tube of the air conditioner is lower than the preset temperature. The lower the compressor frequency, the higher the temperature of the inner tube.
[0032] Specifically, the air conditioner operates under the initial operating conditions upon startup: the air deflector is at its minimum angle and the fan is at its lowest setting. The preset time period depends on the type of air conditioner and environmental conditions, typically a few minutes, used for initial cooling and odor control. After the preset time period, the air conditioner's internal temperature sensor monitors the indoor ambient temperature in real time. The collected temperature data is compared with the user-set target temperature. If the indoor ambient temperature has reached or is close to the user-set temperature, the system prepares to enter the next stage of temperature and odor control strategy. When the indoor ambient temperature reaches the user-set temperature, the compressor's operating frequency begins to decrease. The compressor frequency is adjusted via an inverter or microprocessor; a lower frequency means a decrease in compressor output power and cooling capacity. The rate of frequency reduction is increased during this process. This is done to keep the internal pipe temperature (evaporator temperature) below the preset temperature, preventing sudden temperature increases that could lead to odor release. The preset temperature can be set based on actual testing and user feedback, generally below temperatures that will not produce odors, such as ≤20℃.
[0033] In this embodiment, when the air conditioner is turned on, it is controlled under the first operating condition, which means that the air guide vane is at its minimum angle and the fan is at its lowest setting. After the air conditioner operates according to the first operating condition for a preset period of time, the indoor ambient temperature is acquired. When the indoor ambient temperature reaches the user-set temperature, the compressor frequency is reduced and the rate of decrease in the compressor frequency is increased, so that the temperature of the air conditioner's internal pipe is lower than the preset temperature. Compared with the prior art, where air conditioners are prone to producing odors, this application reduces the generation of air conditioner odors by setting both the air guide vane and fan to their lowest settings when the air conditioner is turned on and reducing the compressor frequency during operation. Therefore, it can alleviate the problem of air conditioners easily producing odors in the prior art and improve the user experience.
[0034] In the specific implementation process, step S202 above increases the rate of decrease of the compressor frequency, so that the temperature of the inner pipe of the air conditioner is lower than the preset temperature. This can be achieved through the following steps: obtaining the current compressor frequency; if the current compressor frequency is less than the preset threshold, continuing to reduce the current compressor frequency to the preset threshold and increasing the rate of decrease of the compressor frequency, so that the temperature of the inner pipe of the air conditioner is lower than the preset temperature.
[0035] Specifically, the process involves several steps: First, the air conditioner obtains the current compressor frequency: The microprocessor or control module inside the unit monitors the compressor's operating frequency in real time. This information can be obtained through an inverter connected to the compressor or directly from the compressor's drive circuit. Frequency data is continuously collected and stored for subsequent comparison and adjustment. Second, a preset threshold is set: Based on the air conditioner's performance and user needs, a preset threshold for the compressor frequency is set. This threshold should ensure that the internal pipe temperature remains low even when the air conditioner is operating at low frequency, effectively reducing odor generation. The preset threshold is typically set based on experimental data and user feedback, aiming to find the optimal balance between cooling performance and energy efficiency. Third, the control module compares the currently collected compressor frequency with the preset threshold. If the current frequency is lower than the preset threshold, it indicates that the air conditioner is in low-frequency operation mode, requiring further reduction of the compressor frequency. Fourth, if the current compressor frequency is indeed lower than the preset threshold, the control module will issue a command to further reduce the compressor's operating frequency by adjusting the inverter's output frequency. This process should be gradual to avoid sudden frequency changes that could cause fluctuations in air conditioner performance. Controlling the internal pipe temperature: As the compressor frequency decreases, the air conditioner's cooling capacity weakens, and the internal pipe temperature gradually rises. To ensure the internal pipe temperature remains below the preset temperature, the air conditioner's control strategy needs to include adjusting the fan speed, controlling the air deflector position, and managing the refrigerant flow. For example, reducing the fan speed decreases the drying speed of the evaporator surface, while adjusting the refrigerant circulation system flow ensures the evaporator remains moist, thereby preventing odor formation.
[0036] In some alternative implementations, after reducing the current compressor frequency to the preset threshold, the method further includes: using a PID control algorithm to control the compressor frequency to stabilize at the preset threshold.
[0037] Specifically, the PID algorithm includes a deterministic error (E), an integral term (I), a derivative term (D), and a proportional term (P). By using the PID control algorithm to achieve precise control of the compressor frequency, it can improve the operating efficiency of the air conditioner, reduce energy consumption, and effectively solve the odor problem caused by changes in the temperature of the inner pipe, thereby improving the overall comfort and satisfaction of users during the use of the air conditioner.
[0038] In some optional implementations, the above step S202 of obtaining the indoor ambient temperature can be achieved by the following steps: obtaining the temperature of the inner pipe of the air conditioner; and obtaining the indoor ambient temperature when the temperature of the inner pipe is lower than the preset temperature.
[0039] Specifically, the temperature sensor inside the air conditioner continuously monitors the surface temperature of the evaporator (inner pipe), and this temperature data is transmitted in real time through a connection with the control module. When the air conditioner is running, the system first checks the current temperature of the evaporator to determine if further control measures are needed. The control module compares the currently obtained inner pipe temperature with a preset temperature. The preset temperature is a threshold set based on the performance of the air conditioner and the need to reduce odors, typically set at 20°C or lower to ensure that the evaporator surface is maintained at a temperature level that minimizes odor generation. If the inner pipe temperature is lower than the preset temperature, it indicates that the current compressor frequency and air conditioner operating status have effectively controlled the evaporator temperature and reduced odor generation. At this point, the system will switch to acquiring the indoor ambient temperature to determine if the compressor frequency needs to be adjusted to maintain the indoor temperature near the set value. The air conditioner's ambient temperature sensor monitors the current indoor temperature, and this temperature data is also transmitted to the control module in real time. The control module compares the collected indoor ambient temperature data with the user-set temperature value to determine the next control strategy. If the indoor ambient temperature has reached or is close to the user-set temperature value, the control module will adjust the compressor frequency as needed. By reducing the frequency, the control module can decrease the air conditioner's cooling power, preventing excessively low or fluctuating indoor temperatures, while maintaining the inner pipe temperature below a preset threshold, thus achieving the dual goals of energy saving and odor reduction. After determining that the compressor frequency needs to be reduced, the control module will use a PID (proportional-integral-derivative) control algorithm or other appropriate control strategies to achieve a smooth frequency reduction, ensuring that the frequency adjustment does not cause drastic changes in indoor temperature, while maintaining stable control of the inner pipe temperature.
[0040] In some alternative implementations, the method further includes controlling the air deflector of the air conditioner to the minimum angle in the event of compressor shutdown or compressor failure.
[0041] In practice, the air conditioner's internal control system continuously monitors the compressor's operating status, including start / stop information, operating frequency, and any potential fault signals. When a compressor stoppage or malfunction is detected, the control program immediately executes a preset air deflector adjustment command. A minimum angle parameter for the air deflector is pre-set in the air conditioner's control software. This angle should ensure that the airflow is downward, away from the user's face and nose area, reducing the direct impact of odors. Different types of air conditioners (such as round cross-flow cabinet units, top-discharge cabinet units, or split units) may require different minimum angle settings to suit their specific air deflector structure and airflow distribution. When a compressor stoppage or malfunction signal is detected, the control module immediately sends a command to the air deflector drive motor to adjust the air deflector to its minimum angle position. This operation is usually completed within seconds, quickly changing the airflow direction to prevent cold air and odors from blowing directly onto the user. The air deflector drive motor should have a position feedback function to ensure that the air deflector is indeed adjusted to the minimum angle. The control module receives this feedback information as the basis for the next operation, ensuring the correct execution of the odor control strategy. To inform users of the current status and operating mode of the air conditioner, visual feedback can be provided through an LCD display or LED indicator lights, informing users that the air conditioner is in compressor shutdown or fault mode, and that the air deflector angle has been adjusted to reduce odors.
[0042] In some alternative implementations, when the indoor ambient temperature reaches the user-set temperature, the method further includes controlling the air guide vane of the air conditioner to a user-set angle.
[0043] Specifically, users set the angle of the air guide vane via the air conditioner's control panel or a remote control device (such as a mobile app). This setting can be static, i.e., setting a fixed angle; or dynamic, for example, users can set the air guide vane to automatically adjust its angle according to temperature changes, or set it to automatically oscillate for a period of time to achieve a more uniform indoor temperature distribution. After receiving the user's set air guide vane angle command, the air conditioner's control module will parse this command based on the current operating mode and indoor environmental conditions, and prepare to execute the corresponding air guide vane adjustment operation. The control module sends a control signal to the air guide vane's drive motor, which will adjust its operating state according to the signal, driving the air guide vane to the user-set angle. This adjustment process should be smooth to avoid sudden mechanical movement that might disturb the user. The air guide vane drive motor should have a position feedback function, capable of transmitting the actual angle information of the air guide vane back to the control module. The control module will compare the user-set angle with the actual feedback angle to ensure that the air guide vane is accurately adjusted to the user's desired position. After the air deflector is adjusted to the user-defined angle, the air conditioner's user interface (such as an LCD screen or LED indicator) will display a confirmation message, informing the user that the air deflector angle has been adjusted. This not only improves the transparency of operation but also makes it convenient for users to view and adjust the air deflector settings at any time.
[0044] In some optional embodiments, the method further includes the following steps: increasing the precooling time of the evaporator or increasing the refrigerant flow rate of the evaporator when the inner tube temperature is higher than the preset temperature.
[0045] In practice, through the above steps, the air conditioner can effectively reduce the evaporator temperature and decrease odor production by increasing the evaporator's pre-cooling time or refrigerant flow when the internal pipe temperature is higher than the preset temperature, while maintaining the air conditioner's cooling efficiency and the comfort of the indoor environment. This dynamic adjustment strategy demonstrates the superiority of intelligent air conditioning systems, which can automatically optimize operating parameters based on real-time environmental conditions and user needs, providing a better user experience.
[0046] To enable those skilled in the art to better understand the technical solution of this application, the implementation process of the air conditioner odor control method of this application will be described in detail below with reference to specific embodiments.
[0047] This embodiment relates to a specific method for controlling odors in an air conditioner, such as... Figure 2 As shown, it includes the following steps:
[0048] Step S1: Start-up phase: When the upper and lower air guide plates are set to the lowest position and the lowest wind speed is started for 15 seconds, switch to the set wind speed. When the T inner pipe is ≤18℃ or the fan has been running for 5 minutes, the air guide plates will operate according to the set setting.
[0049] Step S2: Operation phase: The frequency reduction rate below 30Hz is adjusted from 1Hz / 30s to 1Hz / 10s. During the cooling operation, after reaching the temperature point shutdown condition, the indoor temperature can be maintained at the set temperature, while the internal pipe temperature can be controlled to be ≤20℃, and the low-frequency operation continues to reduce the odor concentration;
[0050] Step S3: Compressor stops or malfunctions cause shutdown: Adjust the upper and lower air guide plates to the lowest position and fix them to control the height of the airflow.
[0051] This application also provides an odor control device for an air conditioner. It should be noted that the odor control device for an air conditioner in this application can be used to execute the odor control method for an air conditioner provided in this application. This device is used to implement the above embodiments and preferred embodiments; details already described will not be repeated. As used below, the term "module" can refer to a combination of software and / or hardware that performs a predetermined function. Although the device described in the following embodiments is preferably implemented in software, hardware implementation, or a combination of software and hardware, is also possible and contemplated.
[0052] The following describes the odor control device for air conditioners provided in the embodiments of this application.
[0053] Figure 3 This is a schematic diagram of an odor control device for an air conditioner according to an embodiment of this application. Figure 3 As shown, the device includes:
[0054] The first control unit 10 is used to control the air conditioner to a first operating condition when the air conditioner is turned on, wherein the first operating condition means that the air guide plate of the air conditioner is at its minimum angle and the fan is at its lowest speed.
[0055] Specifically, this embodiment prevents odor problems from arising in air conditioners at various stages, including when the air conditioner is turned on and during operation. The minimum angle of the air guide vane typically refers to the vane being positioned at its lowest or lowest point. When the air conditioner is turned on, the control circuit adjusts the air guide vane drive motor, moving the vane to the lowest point of its mechanical travel or a preset minimum angle position. This operation ensures that the airflow from the air conditioner outlet is directed away from the user, especially avoiding direct airflow towards the user's nose, thus reducing the amount of odor substances that may accumulate on the evaporator surface during initial startup from being directly introduced into the breathing area. Simultaneously, during the pre-cooling phase of air conditioner startup, the fan is set to its lowest operating speed. This typically means reducing the fan motor speed and airflow, slowing the airflow speed over the evaporator surface. Low airflow helps the evaporator surface temperature drop evenly, preventing odor problems caused by rapid drying. At the same time, lower airflow also reduces the rapid diffusion of odor substances on the evaporator surface, further reducing the odor perceived by the user.
[0056] The reducing unit 20 is used to obtain the indoor ambient temperature after the air conditioner has been running for a preset period of time according to the first operating conditions. When the indoor ambient temperature reaches the user-set temperature, the compressor frequency is reduced and the rate of decrease of the compressor frequency is increased, so that the internal pipe temperature of the air conditioner is lower than the preset temperature. The lower the compressor frequency, the higher the internal pipe temperature.
[0057] Specifically, the air conditioner operates under the initial operating conditions upon startup: the air deflector is at its minimum angle and the fan is at its lowest setting. The preset time period depends on the type of air conditioner and environmental conditions, typically a few minutes, used for initial cooling and odor control. After the preset time period, the air conditioner's internal temperature sensor monitors the indoor ambient temperature in real time. The collected temperature data is compared with the user-set target temperature. If the indoor ambient temperature has reached or is close to the user-set temperature, the system prepares to enter the next stage of temperature and odor control strategy. When the indoor ambient temperature reaches the user-set temperature, the compressor's operating frequency begins to decrease. The compressor frequency is adjusted via an inverter or microprocessor; a lower frequency means a decrease in compressor output power and cooling capacity. The rate of frequency reduction is increased during this process. This is done to keep the internal pipe temperature (evaporator temperature) below the preset temperature, preventing sudden temperature increases that could lead to odor release. The preset temperature can be set based on actual testing and user feedback, generally below temperatures that will not produce odors, such as ≤20℃.
[0058] In this embodiment, when the air conditioner is turned on, it is controlled under the first operating condition, which means that the air guide vane is at its minimum angle and the fan is at its lowest setting. After the air conditioner operates according to the first operating condition for a preset period of time, the indoor ambient temperature is acquired. When the indoor ambient temperature reaches the user-set temperature, the compressor frequency is reduced and the rate of decrease in the compressor frequency is increased, so that the temperature of the air conditioner's internal pipe is lower than the preset temperature. Compared with the prior art, where air conditioners are prone to producing odors, this application reduces the generation of air conditioner odors by setting both the air guide vane and fan to their lowest settings when the air conditioner is turned on and reducing the compressor frequency during operation. Therefore, it can alleviate the problem of air conditioners easily producing odors in the prior art and improve the user experience.
[0059] In the specific implementation process, the above-mentioned reduction unit includes a first acquisition module and a reduction module. The first acquisition module is used to acquire the current compressor frequency. The reduction module is used to continue to reduce the current compressor frequency to the preset threshold and increase the rate of decrease of the compressor frequency when the current compressor frequency is less than the preset threshold, so that the internal pipe temperature of the air conditioner is lower than the preset temperature.
[0060] Specifically, the process involves several steps: First, the air conditioner obtains the current compressor frequency: The microprocessor or control module inside the unit monitors the compressor's operating frequency in real time. This information can be obtained through an inverter connected to the compressor or directly from the compressor's drive circuit. Frequency data is continuously collected and stored for subsequent comparison and adjustment. Second, a preset threshold is set: Based on the air conditioner's performance and user needs, a preset threshold for the compressor frequency is set. This threshold should ensure that the internal pipe temperature remains low even when the air conditioner is operating at low frequency, effectively reducing odor generation. The preset threshold is typically set based on experimental data and user feedback, aiming to find the optimal balance between cooling performance and energy efficiency. Third, the control module compares the currently collected compressor frequency with the preset threshold. If the current frequency is lower than the preset threshold, it indicates that the air conditioner is in low-frequency operation mode, requiring further reduction of the compressor frequency. Fourth, if the current compressor frequency is indeed lower than the preset threshold, the control module will issue a command to further reduce the compressor's operating frequency by adjusting the inverter's output frequency. This process should be gradual to avoid sudden frequency changes that could cause fluctuations in air conditioner performance. Controlling the internal pipe temperature: As the compressor frequency decreases, the air conditioner's cooling capacity weakens, and the internal pipe temperature gradually rises. To ensure the internal pipe temperature remains below the preset temperature, the air conditioner's control strategy needs to include adjusting the fan speed, controlling the air deflector position, and managing the refrigerant flow. For example, reducing the fan speed decreases the drying speed of the evaporator surface, while adjusting the refrigerant circulation system flow ensures the evaporator remains moist, thereby preventing odor formation.
[0061] In some alternative embodiments, the device further includes a second control unit for using a PID control algorithm to stabilize the compressor frequency at the preset threshold after reducing the current compressor frequency to the preset threshold.
[0062] Specifically, the PID algorithm includes a deterministic error (E), an integral term (I), a derivative term (D), and a proportional term (P). By using the PID control algorithm to achieve precise control of the compressor frequency, it can improve the operating efficiency of the air conditioner, reduce energy consumption, and effectively solve the odor problem caused by changes in the temperature of the inner pipe, thereby improving the overall comfort and satisfaction of users during the use of the air conditioner.
[0063] In some optional embodiments, the reducing unit includes a second acquisition module and a third acquisition module. The second acquisition module is used to acquire the temperature of the inner pipe of the air conditioner; the third acquisition module is used to acquire the indoor ambient temperature when the temperature of the inner pipe is lower than the preset temperature.
[0064] Specifically, the temperature sensor inside the air conditioner continuously monitors the surface temperature of the evaporator (inner pipe), and this temperature data is transmitted in real time through a connection with the control module. When the air conditioner is running, the system first checks the current temperature of the evaporator to determine if further control measures are needed. The control module compares the currently obtained inner pipe temperature with a preset temperature. The preset temperature is a threshold set based on the performance of the air conditioner and the need to reduce odors, typically set at 20°C or lower to ensure that the evaporator surface is maintained at a temperature level that minimizes odor generation. If the inner pipe temperature is lower than the preset temperature, it indicates that the current compressor frequency and air conditioner operating status have effectively controlled the evaporator temperature and reduced odor generation. At this point, the system will switch to acquiring the indoor ambient temperature to determine if the compressor frequency needs to be adjusted to maintain the indoor temperature near the set value. The air conditioner's ambient temperature sensor monitors the current indoor temperature, and this temperature data is also transmitted to the control module in real time. The control module compares the collected indoor ambient temperature data with the user-set temperature value to determine the next control strategy. If the indoor ambient temperature has reached or is close to the user-set temperature value, the control module will adjust the compressor frequency as needed. By reducing the frequency, the control module can decrease the air conditioner's cooling power, preventing excessively low or fluctuating indoor temperatures, while maintaining the inner pipe temperature below a preset threshold, thus achieving the dual goals of energy saving and odor reduction. After determining that the compressor frequency needs to be reduced, the control module will use a PID (proportional-integral-derivative) control algorithm or other appropriate control strategies to achieve a smooth frequency reduction, ensuring that the frequency adjustment does not cause drastic changes in indoor temperature, while maintaining stable control of the inner pipe temperature.
[0065] In some alternative embodiments, the device further includes a third control unit for controlling the air deflector of the air conditioner to the minimum angle in the event of compressor shutdown or compressor failure.
[0066] In practice, the air conditioner's internal control system continuously monitors the compressor's operating status, including start / stop information, operating frequency, and any potential fault signals. When a compressor stoppage or malfunction is detected, the control program immediately executes a preset air deflector adjustment command. A minimum angle parameter for the air deflector is pre-set in the air conditioner's control software. This angle should ensure that the airflow is downward, away from the user's face and nose area, reducing the direct impact of odors. Different types of air conditioners (such as round cross-flow cabinet units, top-discharge cabinet units, or split units) may require different minimum angle settings to suit their specific air deflector structure and airflow distribution. When a compressor stoppage or malfunction signal is detected, the control module immediately sends a command to the air deflector drive motor to adjust the air deflector to its minimum angle position. This operation is usually completed within seconds, quickly changing the airflow direction to prevent cold air and odors from blowing directly onto the user. The air deflector drive motor should have a position feedback function to ensure that the air deflector is indeed adjusted to the minimum angle. The control module receives this feedback information as the basis for the next operation, ensuring the correct execution of the odor control strategy. To inform users of the current status and operating mode of the air conditioner, visual feedback can be provided through an LCD display or LED indicator lights, informing users that the air conditioner is in compressor shutdown or fault mode, and that the air deflector angle has been adjusted to reduce odors.
[0067] In some alternative implementations, when the indoor ambient temperature reaches the user-set temperature, the device further includes a fourth control unit for controlling the air guide vane of the air conditioner to the angle set by the user.
[0068] Specifically, users set the angle of the air guide vane via the air conditioner's control panel or a remote control device (such as a mobile app). This setting can be static, i.e., setting a fixed angle; or dynamic, for example, users can set the air guide vane to automatically adjust its angle according to temperature changes, or set it to automatically oscillate for a period of time to achieve a more uniform indoor temperature distribution. After receiving the user's set air guide vane angle command, the air conditioner's control module will parse this command based on the current operating mode and indoor environmental conditions, and prepare to execute the corresponding air guide vane adjustment operation. The control module sends a control signal to the air guide vane's drive motor, which will adjust its operating state according to the signal, driving the air guide vane to the user-set angle. This adjustment process should be smooth to avoid sudden mechanical movement that might disturb the user. The air guide vane drive motor should have a position feedback function, capable of transmitting the actual angle information of the air guide vane back to the control module. The control module will compare the user-set angle with the actual feedback angle to ensure that the air guide vane is accurately adjusted to the user's desired position. After the air deflector is adjusted to the user-defined angle, the air conditioner's user interface (such as an LCD screen or LED indicator) will display a confirmation message, informing the user that the air deflector angle has been adjusted. This not only improves the transparency of operation but also makes it convenient for users to view and adjust the air deflector settings at any time.
[0069] In some alternative embodiments, the device further includes an increasing unit for increasing the precooling time of the evaporator or increasing the refrigerant flow rate of the evaporator when the inner tube temperature is higher than the preset temperature.
[0070] In practice, through the above steps, the air conditioner can effectively reduce the evaporator temperature and decrease odor production by increasing the evaporator's pre-cooling time or refrigerant flow when the internal pipe temperature is higher than the preset temperature, while maintaining the air conditioner's cooling efficiency and the comfort of the indoor environment. This dynamic adjustment strategy demonstrates the superiority of intelligent air conditioning systems, which can automatically optimize operating parameters based on real-time environmental conditions and user needs, providing a better user experience.
[0071] The air conditioner's odor control device includes a processor and a memory. The first control unit and the reduction unit, etc., are all stored as program units in the memory. The processor executes the program units stored in the memory to achieve the corresponding functions. All of the above modules are located in the same processor; or, the above modules are located in different processors in any combination.
[0072] The processor contains a kernel, which retrieves the corresponding program unit from memory. One or more kernels can be configured, and adjusting kernel parameters can prevent air conditioners from producing odors.
[0073] The memory may include non-permanent memory in computer-readable media, such as random access memory (RAM) and / or non-volatile memory, such as read-only memory (ROM) or flash RAM, and the memory includes at least one memory chip.
[0074] This invention provides a computer-readable storage medium including a stored program, wherein the program, when running, controls the device containing the computer-readable storage medium to execute the odor control method of the air conditioner.
[0075] Specifically, methods for controlling odors in air conditioners include:
[0076] Step S201: When the air conditioner is turned on, control the air conditioner to the first operating condition, wherein the first operating condition means that the air guide plate of the air conditioner is at its minimum angle and the fan is at its lowest speed.
[0077] Specifically, this embodiment prevents odor problems from arising in air conditioners at various stages, including when the air conditioner is turned on and during operation. The minimum angle of the air guide vane typically refers to the vane being positioned at its lowest or lowest point. When the air conditioner is turned on, the control circuit adjusts the air guide vane drive motor, moving the vane to the lowest point of its mechanical travel or a preset minimum angle position. This operation ensures that the airflow from the air conditioner outlet is directed away from the user, especially avoiding direct airflow towards the user's nose, thus reducing the amount of odor substances that may accumulate on the evaporator surface during initial startup from being directly introduced into the breathing area. Simultaneously, during the pre-cooling phase of air conditioner startup, the fan is set to its lowest operating speed. This typically means reducing the fan motor speed and airflow, slowing the airflow speed over the evaporator surface. Low airflow helps the evaporator surface temperature drop evenly, preventing odor problems caused by rapid drying. At the same time, lower airflow also reduces the rapid diffusion of odor substances on the evaporator surface, further reducing the odor perceived by the user.
[0078] Step S202: After the air conditioner has been running for a preset period of time according to the first operating conditions, the indoor ambient temperature is obtained. When the indoor ambient temperature reaches the user-set temperature, the compressor frequency is reduced and the rate of decrease of the compressor frequency is increased, so that the temperature of the inner tube of the air conditioner is lower than the preset temperature. The lower the compressor frequency, the higher the temperature of the inner tube.
[0079] Specifically, the air conditioner operates under the initial operating conditions upon startup: the air deflector is at its minimum angle and the fan is at its lowest setting. The preset time period depends on the type of air conditioner and environmental conditions, typically a few minutes, used for initial cooling and odor control. After the preset time period, the air conditioner's internal temperature sensor monitors the indoor ambient temperature in real time. The collected temperature data is compared with the user-set target temperature. If the indoor ambient temperature has reached or is close to the user-set temperature, the system prepares to enter the next stage of temperature and odor control strategy. When the indoor ambient temperature reaches the user-set temperature, the compressor's operating frequency begins to decrease. The compressor frequency is adjusted via an inverter or microprocessor; a lower frequency means a decrease in compressor output power and cooling capacity. The rate of frequency reduction is increased during this process. This is done to keep the internal pipe temperature (evaporator temperature) below the preset temperature, preventing sudden temperature increases that could lead to odor release. The preset temperature can be set based on actual testing and user feedback, generally below temperatures that will not produce odors, such as ≤20℃.
[0080] This invention provides an air conditioner, including a processor, a memory, and a program stored in the memory and executable on the processor. When the processor executes the program, it performs at least the following steps:
[0081] Step S201: When the air conditioner is turned on, control the air conditioner to the first operating condition, wherein the first operating condition means that the air guide plate of the air conditioner is at its minimum angle and the fan is at its lowest speed.
[0082] Specifically, this embodiment prevents odor problems from arising in air conditioners at various stages, including when the air conditioner is turned on and during operation.

Low airflow helps the evaporator surface temperature drop evenly, preventing odor problems caused by rapid drying. At the same time, lower airflow also reduces the rapid diffusion of odor substances on the evaporator surface, further reducing the odor perceived by the user.
[0083] Step S202: After the air conditioner has been running for a preset period of time according to the first operating conditions, the indoor ambient temperature is obtained. When the indoor ambient temperature reaches the user-set temperature, the compressor frequency is reduced and the rate of decrease of the compressor frequency is increased, so that the temperature of the inner tube of the air conditioner is lower than the preset temperature. The lower the compressor frequency, the higher the temperature of the inner tube.
