Description

Technical Field

[0001] The present application relates to the technical field of air conditioner control, and in particular, to an air conditioner anti-odor control method, device, computer-readable storage medium and air conditioner. Background Art

[0002] The odor of household air conditioners is a problem for the entire industry. The sources of odor are complex and all domestic and foreign brands have this problem. There is no ultimate solution yet. The cause of the odor is still undetermined in academia and industry. The mainstream view is that the phenomenon is strongly related to the odor of hydrophilic aluminum foil coating, environmental odor adsorption, and microbial odor.

[0003] The prior art discloses a method for controlling the odor of an air conditioner, an air conditioner and its control device, and a storage medium. The method includes: obtaining the indoor water vapor dew point temperature T0, obtaining the indoor heat exchanger temperature T1, judging whether the temperature judgment condition T1<(T0-A) is established, and A is the preset temperature data; based on the establishment of the temperature judgment condition, the air conditioner is controlled to operate in a setting working mode, and a liquid film is continuously formed on the indoor heat exchanger. When the temperature judgment condition is established, the air conditioner is controlled to operate in a setting working mode, and a liquid film is continuously formed on the indoor heat exchanger. The liquid film covers the acidic VOC (volatile organic compounds, VOC for short) enriched in the indoor heat exchanger. The liquid film can not only well cover the odor emitted by the acidic VOC enriched in the indoor heat exchanger, but also slowly wash away the VOC enriched in the indoor heat exchanger, so that the odor blown out of the air conditioner is controlled within the human olfactory threshold. This solution does not require the use of alcohol or other alkaline cleaning agents, and can solve the problem of the air conditioner emitting a large odor indoors. However, the air conditioner heat exchanger cannot maintain the liquid film all the time. When the indoor temperature reaches the preset value, the compressor frequency will decrease, the internal pipe temperature will increase, and it will be higher than the air dew point, and it may even reach the temperature point and shut down. After shutdown, the water film disappears and it is very easy to blow out odor.

[0004] Therefore, how to prevent the air conditioner from generating odor is a problem that needs to be solved urgently. Summary of the invention

[0023] For the convenience of description, some nouns or terms involved in the embodiments of the present application are explained below:

[0024] The internal pipe temperature of the air conditioner: refers to the temperature of the refrigerant pipe inside the air conditioner.

[0025] As introduced in the background technology, air conditioners in the prior art are prone to produce odors. To solve the problem of air conditioners easily producing odors, the embodiments of the present application provide an air conditioner anti-odor control method, device, computer-readable storage medium and air conditioner.

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0027] In this embodiment, a method for preventing odor from being controlled in an air conditioner running on a mobile terminal, a computer terminal or a similar computing device is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0028] Figure 1 FIG. 1 is a flow chart of an anti-odor control method for an air conditioner according to an embodiment of the present application. Figure 1 As shown, the method comprises the following steps:

[0029] Step S201, when the air conditioner is turned on, controlling the air conditioner to be in a first operating condition, wherein the first operating condition indicates that the air guide plate of the air conditioner is at a minimum angle and the fan is at a lowest gear;

[0030] Specifically, the present embodiment prevents the problem of odor generation in the air conditioner from various stages such as the start-up and operation of the air conditioner. The minimum angle of the air guide plate usually refers to the air guide plate facing the lowest or lowest limit position. When the air conditioner is turned on, the air guide plate drive motor is adjusted by the control circuit to move the air guide plate to the lowest end of its mechanical stroke or the preset lowest angle position. The purpose of this operation is to ensure that the wind direction of the air outlet of the air conditioner is away from the user, especially to avoid blowing directly to the user's nose, so as to reduce the odor substances that may be accumulated on the surface of the evaporator in the initial stage of startup and directly send them into the human breathing area. At the same time, in the pre-cooling stage of the air conditioner startup, the fan is set to the lowest operating gear. This usually means reducing the speed of the fan motor, reducing the air volume, and slowing down the air flow speed on the surface of the evaporator. Low wind speed helps to evenly reduce the temperature of the evaporator surface and avoid odor problems caused by rapid air drying. At the same time, a lower air volume can also reduce the rapid diffusion of odor substances on the surface of the evaporator, further reducing the odor perceived by the user.

[0031] Step S202, after the air conditioner runs for a preset time period according to the first operating condition, the indoor ambient temperature is obtained, and when the indoor ambient temperature reaches the temperature set by the user, the compressor frequency is reduced and the decreasing rate of the compressor frequency is increased, so that the inner tube temperature of the air conditioner is lower than the preset temperature, wherein the lower the compressor frequency, the higher the inner tube temperature.

[0032] Specifically, the air conditioner operates according to the first operating condition at the initial startup, that is, the air guide plate is at the minimum angle and the fan is at the lowest gear. The preset time period is set according to the type of air conditioner and environmental conditions, generally a few minutes, and this time is used for preliminary cooling and odor control. After the preset time period, the temperature sensor inside the air conditioner will monitor the indoor ambient temperature in real time. The collected temperature data is compared with the target temperature set by the user. If it is found that the indoor ambient temperature has reached or is close to the temperature set by the user, it will be ready to enter the next stage of temperature and odor control strategy. When the indoor ambient temperature reaches the user-set temperature, the operating frequency of the compressor begins to decrease. The adjustment of the compressor frequency is controlled by an inverter or a microprocessor. The reduction in frequency means that the output power of the compressor decreases and the cooling capacity decreases. In the process of reducing the compressor frequency, the rate of frequency reduction is increased. The purpose of this is to keep the inner tube temperature (evaporator temperature) below the preset temperature to prevent the release of odor due to a sudden increase in temperature. The preset temperature can be set according to actual tests and user feedback, and is generally set below the temperature that does not produce odor, such as ≤20℃.

[0033] Through this embodiment, when the air conditioner is turned on, the air conditioner is controlled to the first operating condition, wherein the first operating condition indicates that the air guide plate of the air conditioner is at the minimum angle and the fan is at the lowest gear; after the air conditioner runs for a preset period of time according to the first operating condition, the indoor ambient temperature is obtained, and 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 inner tube temperature of the air conditioner is lower than the preset temperature. Compared with the prior art, in which the air conditioner is prone to produce odor, the present application reduces the generation of air-conditioning odor by setting the air guide plate and the fan to the lowest gear when the air conditioner is turned on, and reducing the compressor frequency during the operation stage. Therefore, it can alleviate the problem of the air conditioner being prone to produce odor in the prior art and improve the user experience.

[0034] In the specific implementation process, the above-mentioned step S202 increases the decreasing rate of the compressor frequency so that the inner tube temperature of the air conditioner is lower than the preset temperature, which can be achieved through the following steps: obtaining the current compressor frequency; when the current compressor frequency is less than the preset threshold, continuing to reduce the current compressor frequency to the preset threshold and increasing the decreasing rate of the compressor frequency so that the inner tube temperature of the air conditioner is lower than the preset temperature.

[0035] Specifically, obtain the current compressor frequency: the microprocessor or control module inside the air conditioner will monitor the operating frequency of the compressor in real time. This information can be obtained through the inverter connected to the compressor or directly from the drive circuit of the compressor. The frequency data is continuously collected and stored for subsequent comparison and adjustment. Set a preset threshold: set a preset threshold for the compressor frequency according to the performance of the air conditioner and user needs. This threshold should ensure that the temperature of the inner tube can still be kept at a low level when the air conditioner is running at a low frequency, effectively reducing the generation of odor. The setting of the preset threshold is usually based on experimental data and user feedback. It is necessary to find the best balance point while ensuring the cooling effect and energy efficiency of the air conditioner. Compare the current frequency with the preset threshold: the control module compares the currently collected compressor frequency with the preset threshold. If the current frequency is lower than the preset threshold, it means that the air conditioner is in a low-frequency operation mode, and the compressor frequency needs to be further reduced. Reduce the compressor frequency: If the current compressor frequency is indeed lower than the preset threshold, the control module will issue an instruction to further reduce the operating frequency of the compressor by adjusting the output frequency of the inverter. This process should be carried out gradually to avoid sudden changes in frequency causing fluctuations in air conditioner performance. Control the inner tube temperature: As the compressor frequency decreases, the air conditioner's cooling capacity decreases and the inner tube temperature gradually rises. In order to ensure that the inner tube temperature is lower than the preset temperature, the air conditioner's control strategy needs to include the adjustment of the fan speed, the control of the air guide plate position, and the management of the refrigerant flow. For example, the fan speed can be reduced to reduce the air drying speed of the evaporator surface, and the flow of the refrigerant circulation system can be adjusted to ensure the evaporator is moistened, thereby preventing the generation of odor.

[0036] In some optional 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 determining the error (E), integral term (I), differential term (D) and proportional term (P). The PID control algorithm is used to achieve precise control of the compressor frequency. This can improve the operating efficiency of the air conditioner, reduce energy consumption, and effectively solve the odor problem caused by changes in the inner pipe temperature, thereby improving the user's overall comfort and satisfaction during the use of the air conditioner.

[0038] In some optional implementations, the above step S202 of obtaining the indoor ambient temperature can be implemented by the following steps: obtaining the inner tube temperature of the air conditioner; and when the inner tube temperature is lower than the preset temperature, obtaining the indoor ambient temperature.

[0039] Specifically, the temperature sensor inside the air conditioner continuously monitors the surface temperature of the evaporator (inner tube), and this temperature data is transmitted in real time through the connection with the control module. When the air conditioner is running, the system will first check the current temperature of the evaporator to determine whether further control measures are needed. The control module compares the currently obtained inner tube temperature with the preset temperature. The preset temperature is a threshold set according to the performance of the air conditioner and the need to reduce odors. It is usually set at 20°C or lower to ensure that the evaporator surface is maintained at a temperature level that is not easy to produce odors. If the inner tube temperature is lower than the preset temperature, it means that the current compressor frequency and air conditioner operation status have effectively controlled the evaporator temperature and reduced the generation of odors. At this time, the system will turn to obtain the indoor ambient temperature to determine whether the compressor frequency needs to be adjusted to maintain the indoor temperature near the set value. The ambient temperature sensor of the air conditioner monitors the current indoor temperature, and the temperature data is also transmitted to the control module in real time. The control module compares the collected indoor ambient temperature data with the temperature value set by the user to determine the next control strategy. If the indoor ambient temperature has reached or is close to the temperature value set by the user, the control module will adjust the compressor frequency as needed. By reducing the frequency, the control module can reduce the cooling power of the air conditioner to prevent the indoor temperature from being too low or fluctuating, while keeping the inner tube temperature below the preset threshold to achieve the dual goals of energy saving and odor reduction. After determining that the compressor frequency needs to be reduced, the control module will use the PID (proportional-integral-differential) control algorithm or other appropriate control strategy to achieve a smooth reduction in frequency, ensuring that the frequency adjustment does not cause drastic changes in the indoor temperature while maintaining stable control of the inner tube temperature.

[0040] In some optional embodiments, the method further includes: when the compressor is shut down or fails, controlling the air guide plate of the air conditioner to be the minimum angle.

[0041] In the specific implementation process, the control system inside the air conditioner continuously monitors the operating status of the compressor, including the compressor start and stop information, operating frequency and any potential fault signals. When the compressor is detected to be stopped or faulty, the control program will immediately execute the preset air guide adjustment command. In the control software of the air conditioner, a minimum angle parameter of the air guide is pre-set. This angle should ensure that the airflow direction is downward, away from the user's face and nose area, and reduce the impact of direct air supply of odor. Different types of air conditioners (such as round cross-flow cabinets, cabinets with upper air outlets or split units) may need to set different minimum angles to adapt to their specific air guide structure and air flow distribution. When the signal of compressor shutdown or fault is detected, the control module immediately sends a command to the air guide drive motor to adjust the air guide to the minimum angle position. This operation is usually completed within a few seconds, quickly changing the airflow direction to prevent cold air and odor from blowing directly to the user. The air guide drive motor should have a position feedback function to ensure that the air guide is indeed adjusted to the minimum angle. The control module will receive this feedback information as the basis for the next operation to ensure the correct execution of the odor control strategy. To let users know the current status and operating mode of the air conditioner, visual feedback can be provided through the LCD display or LED indicator to inform users that the air conditioner is in compressor shutdown or fault mode and that the air guide plate angle has been adjusted to reduce odor.

[0042] In some optional embodiments, when the indoor ambient temperature reaches a temperature set by a user, the method further includes: controlling an air guide plate of the air conditioner to an angle set by a user.

[0043] Specifically, the user sets the angle of the air deflector through the control panel of the air conditioner or a remote control device (such as a mobile phone APP). This setting can be static, that is, a fixed angle is set; it can also be dynamic. For example, the user can set the air deflector to automatically adjust the angle as the temperature changes, or set the air deflector to automatically swing within a period of time to achieve a more uniform indoor temperature distribution. After receiving the air deflector angle instruction set by the user, the control module of the air conditioner will parse this instruction according to the current operating mode and indoor environmental conditions, and prepare to perform the corresponding air deflector adjustment operation. The control module sends a control signal to the drive motor of the air deflector, and the drive motor will adjust its working state according to the signal to drive the air deflector to the angle set by the user. This adjustment process should be smooth to avoid sudden mechanical movement causing interference to the user. The air deflector drive motor should have a position feedback function, which can transmit the actual angle information of the air deflector back to the control module. The control module will compare the angle set by the user with the actual feedback angle to ensure that the air deflector is accurately adjusted to the position expected by the user. After the air deflector is adjusted to the angle set by the user, the user interface of the air conditioner (such as an LCD screen or an LED indicator) will display a confirmation message to inform the user that the air deflector angle has been adjusted. This not only improves the transparency of the operation, but also makes it convenient for the user to check and adjust the settings of the air deflector at any time.

[0044] In some optional embodiments, the method further includes the following steps: when the temperature of the inner tube is higher than the preset temperature, increasing the precooling time of the evaporator or increasing the flow rate of the refrigerant of the evaporator.

[0045] In the specific implementation process, through the above steps, the air conditioner can effectively reduce the evaporator temperature and reduce the generation of odor by increasing the precooling time of the evaporator or the refrigerant flow rate when the inner tube temperature is higher than the preset temperature, while maintaining the cooling efficiency of the air conditioner and the comfort of the indoor environment. This dynamic adjustment strategy reflects the superiority of the intelligent air conditioning system, which can automatically optimize the operating parameters according to real-time environmental conditions and user needs to provide a better user experience.

[0046] In order to enable those skilled in the art to more clearly understand the technical solution of the present application, the implementation process of the anti-odor control method for the air conditioner of the present application will be described in detail below in combination with specific embodiments.

[0047] This embodiment relates to a specific method for preventing odor from being controlled in an air conditioner. Figure 2 As shown, the following steps are included:

[0048] Step S1: Start-up stage: the upper and lower air guide plates are moved to the lowest setting, and the lowest wind speed is started for 15 seconds, and then the wind speed is set. When the temperature of the inner tube T is ≤18℃ or the fan has been running for 5 minutes, the air guide plates operate according to the setting;

[0049] Step S2: Operation phase: The frequency reduction rate of low frequency below 30Hz is adjusted from 1Hz / 30s to 1Hz / 10s. During the refrigeration operation, after reaching the temperature point shutdown condition, the indoor temperature can be maintained at the set temperature, and the internal pipe temperature can be controlled to ≤20℃, and the low frequency operation is continued to reduce the odor concentration;

[0050] Step S3: The compressor stops or stops due to a fault: the upper and lower air guide plates are adjusted to the lowest position to control the height of the air.

[0051] The embodiment of the present application also provides an anti-odor control device for an air conditioner. It should be noted that the anti-odor control device for the air conditioner in the embodiment of the present application can be used to execute the anti-odor control method for the air conditioner provided in the embodiment of the present application. The device is used to implement the above-mentioned embodiments and preferred implementation modes, and the descriptions that have been made will not be repeated. As used below, the term "module" can implement a combination of software and / or hardware for a predetermined function. Although the device described in the following embodiments is preferably implemented in software, the implementation of hardware, or a combination of software and hardware, is also possible and conceived.

[0052] The anti-odor control device for the air conditioner provided in the embodiment of the present application is introduced below.

[0053] Figure 3 Schematic diagram of an anti-odor control device for an air conditioner according to an embodiment of the present application. Figure 3 As shown, the device comprises:

[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 indicates that the air guide plate of the air conditioner is at a minimum angle and the fan is at a lowest gear;

[0055] Specifically, the present embodiment prevents the problem of odor generation in the air conditioner from various stages such as the start-up and operation of the air conditioner. The minimum angle of the air guide plate usually refers to the air guide plate facing the lowest or lowest limit position. When the air conditioner is turned on, the air guide plate drive motor is adjusted by the control circuit to move the air guide plate to the lowest end of its mechanical stroke or the preset lowest angle position. The purpose of this operation is to ensure that the wind direction of the air outlet of the air conditioner is away from the user, especially to avoid blowing directly to the user's nose, so as to reduce the odor substances that may be accumulated on the surface of the evaporator in the initial stage of startup and directly send them into the human breathing area. At the same time, in the pre-cooling stage of the air conditioner startup, the fan is set to the lowest operating gear. This usually means reducing the speed of the fan motor, reducing the air volume, and slowing down the air flow speed on the surface of the evaporator. Low wind speed helps to evenly reduce the temperature of the evaporator surface and avoid odor problems caused by rapid air drying. At the same time, a lower air volume can also reduce the rapid diffusion of odor substances on the surface of the evaporator, 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 time period according to the first operating condition, and when the indoor ambient temperature reaches the temperature set by the user, reduce the compressor frequency and increase the decreasing rate of the compressor frequency so that the inner tube temperature of the air conditioner is lower than the preset temperature, wherein the lower the compressor frequency, the higher the inner tube temperature.

[0057] Specifically, the air conditioner operates according to the first operating condition at the initial startup, that is, the air guide plate is at the minimum angle and the fan is at the lowest gear. The preset time period is set according to the type of air conditioner and environmental conditions, generally a few minutes, and this time is used for preliminary cooling and odor control. After the preset time period, the temperature sensor inside the air conditioner will monitor the indoor ambient temperature in real time. The collected temperature data is compared with the target temperature set by the user. If it is found that the indoor ambient temperature has reached or is close to the temperature set by the user, it will be ready to enter the next stage of temperature and odor control strategy. When the indoor ambient temperature reaches the user-set temperature, the operating frequency of the compressor begins to decrease. The adjustment of the compressor frequency is controlled by an inverter or a microprocessor. The reduction in frequency means that the output power of the compressor decreases and the cooling capacity decreases. In the process of reducing the compressor frequency, the rate of frequency reduction is increased. The purpose of this is to keep the inner tube temperature (evaporator temperature) below the preset temperature to prevent the release of odor due to a sudden increase in temperature. The preset temperature can be set according to actual tests and user feedback, and is generally set below the temperature that does not produce odor, such as ≤20℃.

[0058] Through this embodiment, when the air conditioner is turned on, the air conditioner is controlled to the first operating condition, wherein the first operating condition indicates that the air guide plate of the air conditioner is at the minimum angle and the fan is at the lowest gear; after the air conditioner runs for a preset period of time according to the first operating condition, the indoor ambient temperature is obtained, and 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 inner tube temperature of the air conditioner is lower than the preset temperature. Compared with the prior art, in which the air conditioner is prone to produce odor, the present application reduces the generation of air-conditioning odor by setting the air guide plate and the fan to the lowest gear when the air conditioner is turned on, and reducing the compressor frequency during the operation stage. Therefore, it can alleviate the problem of the air conditioner being prone to produce odor in the prior art and improve the user experience.

[0059] During 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 obtain the current compressor frequency; the reduction module is used to continue to reduce the current compressor frequency to the preset threshold and increase the decrease rate of the compressor frequency when the current compressor frequency is less than the preset threshold, so that the inner tube temperature of the air conditioner is lower than the preset temperature.

[0060] Specifically, obtain the current compressor frequency: the microprocessor or control module inside the air conditioner will monitor the operating frequency of the compressor in real time. This information can be obtained through the inverter connected to the compressor or directly from the drive circuit of the compressor. The frequency data is continuously collected and stored for subsequent comparison and adjustment. Set a preset threshold: set a preset threshold for the compressor frequency according to the performance of the air conditioner and user needs. This threshold should ensure that the temperature of the inner tube can still be kept at a low level when the air conditioner is running at a low frequency, effectively reducing the generation of odor. The setting of the preset threshold is usually based on experimental data and user feedback. It is necessary to find the best balance point while ensuring the cooling effect and energy efficiency of the air conditioner. Compare the current frequency with the preset threshold: the control module compares the currently collected compressor frequency with the preset threshold. If the current frequency is lower than the preset threshold, it means that the air conditioner is in a low-frequency operation mode, and the compressor frequency needs to be further reduced. Reduce the compressor frequency: If the current compressor frequency is indeed lower than the preset threshold, the control module will issue an instruction to further reduce the operating frequency of the compressor by adjusting the output frequency of the inverter. This process should be carried out gradually to avoid sudden changes in frequency causing fluctuations in air conditioner performance. Control the inner tube temperature: As the compressor frequency decreases, the air conditioner's cooling capacity decreases and the inner tube temperature gradually rises. In order to ensure that the inner tube temperature is lower than the preset temperature, the air conditioner's control strategy needs to include the adjustment of the fan speed, the control of the air guide plate position, and the management of the refrigerant flow. For example, the fan speed can be reduced to reduce the air drying speed of the evaporator surface, and the flow of the refrigerant circulation system can be adjusted to ensure the evaporator is moistened, thereby preventing the generation of odor.

[0061] In some optional embodiments, the device further includes a second control unit for controlling the compressor frequency to be stable at the preset threshold by using a PID control algorithm after reducing the current compressor frequency to the preset threshold.

[0062] Specifically, the PID algorithm includes determining the error (E), integral term (I), differential term (D) and proportional term (P). The PID control algorithm is used to achieve precise control of the compressor frequency. This can improve the operating efficiency of the air conditioner, reduce energy consumption, and effectively solve the odor problem caused by changes in the inner pipe temperature, thereby improving the user's overall comfort and satisfaction during the use of the air conditioner.

[0063] In some optional embodiments, the reduction unit includes a second acquisition module and a third acquisition module, the second acquisition module is used to obtain the inner tube temperature of the air conditioner; the third acquisition module is used to obtain the indoor ambient temperature when the inner tube temperature is lower than the preset temperature.

[0064] Specifically, the temperature sensor inside the air conditioner continuously monitors the surface temperature of the evaporator (inner tube), and this temperature data is transmitted in real time through the connection with the control module. When the air conditioner is running, the system will first check the current temperature of the evaporator to determine whether further control measures are needed. The control module compares the currently obtained inner tube temperature with the preset temperature. The preset temperature is a threshold set according to the performance of the air conditioner and the need to reduce odors. It is usually set at 20°C or lower to ensure that the evaporator surface is maintained at a temperature level that is not easy to produce odors. If the inner tube temperature is lower than the preset temperature, it means that the current compressor frequency and air conditioner operation status have effectively controlled the evaporator temperature and reduced the generation of odors. At this time, the system will turn to obtain the indoor ambient temperature to determine whether the compressor frequency needs to be adjusted to maintain the indoor temperature near the set value. The ambient temperature sensor of the air conditioner monitors the current indoor temperature, and the temperature data is also transmitted to the control module in real time. The control module compares the collected indoor ambient temperature data with the temperature value set by the user to determine the next control strategy. If the indoor ambient temperature has reached or is close to the temperature value set by the user, the control module will adjust the compressor frequency as needed. By reducing the frequency, the control module can reduce the cooling power of the air conditioner to prevent the indoor temperature from being too low or fluctuating, while keeping the inner tube temperature below the preset threshold to achieve the dual goals of energy saving and odor reduction. After determining that the compressor frequency needs to be reduced, the control module will use the PID (proportional-integral-differential) control algorithm or other appropriate control strategy to achieve a smooth reduction in frequency, ensuring that the frequency adjustment does not cause drastic changes in the indoor temperature while maintaining stable control of the inner tube temperature.

[0065] In some optional embodiments, the device further comprises a third control unit, configured to control the air guide plate of the air conditioner to be at the minimum angle when the compressor stops or fails.

[0066] In the specific implementation process, the control system inside the air conditioner continuously monitors the operating status of the compressor, including the compressor start and stop information, operating frequency and any potential fault signals. When the compressor is detected to be stopped or faulty, the control program will immediately execute the preset air guide adjustment command. In the control software of the air conditioner, a minimum angle parameter of the air guide is pre-set. This angle should ensure that the airflow direction is downward, away from the user's face and nose area, and reduce the impact of direct air supply of odor. Different types of air conditioners (such as round cross-flow cabinets, cabinets with upper air outlets or split units) may need to set different minimum angles to adapt to their specific air guide structure and air flow distribution. When the signal of compressor shutdown or fault is detected, the control module immediately sends a command to the air guide drive motor to adjust the air guide to the minimum angle position. This operation is usually completed within a few seconds, quickly changing the airflow direction to prevent cold air and odor from blowing directly to the user. The air guide drive motor should have a position feedback function to ensure that the air guide is indeed adjusted to the minimum angle. The control module will receive this feedback information as the basis for the next operation to ensure the correct execution of the odor control strategy. To let users know the current status and operating mode of the air conditioner, visual feedback can be provided through the LCD display or LED indicator to inform users that the air conditioner is in compressor shutdown or fault mode and that the air guide plate angle has been adjusted to reduce odor.

[0067] In some optional embodiments, when the indoor ambient temperature reaches a temperature set by a user, the device further comprises a fourth control unit for controlling the air guide plate of the air conditioner to an angle set by a user.

[0068] Specifically, the user sets the angle of the air deflector through the control panel of the air conditioner or a remote control device (such as a mobile phone APP). This setting can be static, that is, a fixed angle is set; it can also be dynamic. For example, the user can set the air deflector to automatically adjust the angle as the temperature changes, or set the air deflector to automatically swing within a period of time to achieve a more uniform indoor temperature distribution. After receiving the air deflector angle instruction set by the user, the control module of the air conditioner will parse this instruction according to the current operating mode and indoor environmental conditions, and prepare to perform the corresponding air deflector adjustment operation. The control module sends a control signal to the drive motor of the air deflector, and the drive motor will adjust its working state according to the signal to drive the air deflector to the angle set by the user. This adjustment process should be smooth to avoid sudden mechanical movement causing interference to the user. The air deflector drive motor should have a position feedback function, which can transmit the actual angle information of the air deflector back to the control module. The control module will compare the angle set by the user with the actual feedback angle to ensure that the air deflector is accurately adjusted to the position expected by the user. After the air deflector is adjusted to the angle set by the user, the user interface of the air conditioner (such as an LCD screen or an LED indicator) will display a confirmation message to inform the user that the air deflector angle has been adjusted. This not only improves the transparency of the operation, but also makes it convenient for the user to check and adjust the settings of the air deflector at any time.

[0069] In some optional embodiments, the device further comprises an increasing unit for increasing the precooling time of the evaporator or increasing the flow rate of the refrigerant of the evaporator when the temperature of the inner tube is higher than the preset temperature.

[0070] In the specific implementation process, through the above steps, the air conditioner can effectively reduce the evaporator temperature and reduce the generation of odor by increasing the precooling time of the evaporator or the refrigerant flow rate when the inner tube temperature is higher than the preset temperature, while maintaining the cooling efficiency of the air conditioner and the comfort of the indoor environment. This dynamic adjustment strategy reflects the superiority of the intelligent air conditioning system, which can automatically optimize the operating parameters according to real-time environmental conditions and user needs to provide a better user experience.

[0071] The anti-odor control device for the air conditioner includes a processor and a memory, the first control unit and the reduction unit are stored in the memory as program units, and the processor executes the program units stored in the memory to implement corresponding functions. The modules are all located in the same processor; or, the modules are located in different processors in any combination.

[0072] The processor includes a kernel, which calls the corresponding program unit from the memory. One or more kernels can be set, and the air conditioner can be prevented from generating odor by adjusting the kernel parameters.

[0073] The memory may include non-permanent memory in a computer-readable medium, 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] An embodiment of the present invention provides a computer-readable storage medium, which includes a stored program, wherein when the program is run, the device where the computer-readable storage medium is located is controlled to execute the anti-odor control method for the air conditioner.

[0075] Specifically, the anti-odor control method of the air conditioner includes:

[0076] Step S201, when the air conditioner is turned on, controlling the air conditioner to be in a first operating condition, wherein the first operating condition indicates that the air guide plate of the air conditioner is at a minimum angle and the fan is at a lowest gear;

[0077] Specifically, the present embodiment prevents the problem of odor generation in the air conditioner from various stages such as the start-up and operation of the air conditioner. The minimum angle of the air guide plate usually refers to the air guide plate facing the lowest or lowest limit position. When the air conditioner is turned on, the air guide plate drive motor is adjusted by the control circuit to move the air guide plate to the lowest end of its mechanical stroke or the preset lowest angle position. The purpose of this operation is to ensure that the wind direction of the air outlet of the air conditioner is away from the user, especially to avoid blowing directly to the user's nose, so as to reduce the odor substances that may be accumulated on the surface of the evaporator in the initial stage of startup and directly send them into the human breathing area. At the same time, in the pre-cooling stage of the air conditioner startup, the fan is set to the lowest operating gear. This usually means reducing the speed of the fan motor, reducing the air volume, and slowing down the air flow speed on the surface of the evaporator. Low wind speed helps to evenly reduce the temperature of the evaporator surface and avoid odor problems caused by rapid air drying. At the same time, a lower air volume can also reduce the rapid diffusion of odor substances on the surface of the evaporator, further reducing the odor perceived by the user.

[0078] Step S202, after the air conditioner runs for a preset time period according to the first operating condition, the indoor ambient temperature is obtained, and when the indoor ambient temperature reaches the temperature set by the user, the compressor frequency is reduced and the decreasing rate of the compressor frequency is increased, so that the inner tube temperature of the air conditioner is lower than the preset temperature, wherein the lower the compressor frequency, the higher the inner tube temperature.

[0079] Specifically, the air conditioner operates according to the first operating condition at the initial startup, that is, the air guide plate is at the minimum angle and the fan is at the lowest gear. The preset time period is set according to the type of air conditioner and environmental conditions, generally a few minutes, and this time is used for preliminary cooling and odor control. After the preset time period, the temperature sensor inside the air conditioner will monitor the indoor ambient temperature in real time. The collected temperature data is compared with the target temperature set by the user. If it is found that the indoor ambient temperature has reached or is close to the temperature set by the user, it will be ready to enter the next stage of temperature and odor control strategy. When the indoor ambient temperature reaches the user-set temperature, the operating frequency of the compressor begins to decrease. The adjustment of the compressor frequency is controlled by an inverter or a microprocessor. The reduction in frequency means that the output power of the compressor decreases and the cooling capacity decreases. In the process of reducing the compressor frequency, the rate of frequency reduction is increased. The purpose of this is to keep the inner tube temperature (evaporator temperature) below the preset temperature to prevent the release of odor due to a sudden increase in temperature. The preset temperature can be set according to actual tests and user feedback, and is generally set below the temperature that does not produce odor, such as ≤20℃.
