[0020] As people's demands for indoor air quality increase, air conditioners equipped with positive and negative ion generators have become mainstream products in the market. They release positive and negative ions to sterilize, deodorize, and purify the air, and are widely used in homes and offices. However, air conditioners produce condensation during cooling mode, which adheres to the electrodes of the ion generator or the surface of the unit. Simultaneously, varying ambient humidity levels cause differences in air resistivity; higher humidity results in lower air resistivity, making it easier for discharge phenomena to occur. Both of these situations can easily lead to abnormal arcing and operating noise in the ion generator, and may even cause inter-electrode discharge or discharge between the electrodes and the air conditioner's injection-molded parts. This not only affects the purification effect but also shortens the equipment's lifespan, poses safety hazards, and fails to meet users' demands for the safety and stability of air conditioners.

[0021] Based on this, the following embodiments are proposed.

[0022] Example 1: like Figure 1 , 7 As shown, this embodiment provides a method for controlling the ion generator of an air conditioner, including: acquiring the air conditioner's operating mode and the ambient humidity value; The power supply voltage of the ion generator is controlled and adjusted according to the ambient humidity value and the air conditioner's operating mode.

[0023] In this embodiment, the air conditioner main control module serves as the control component of the control system, the humidity detection module can collect environmental data in real time, the voltage regulation module, as a power device, can perform voltage regulation, and the ion generator is the final actuator of the control system, used to ultimately achieve the air purification function.

[0024] When the air conditioner is running, the control system activates immediately upon the user's command to turn on the internal negative ion purification function. The humidity detection module continuously collects real-time humidity data of the indoor space where the air conditioner is located, transmitting the collected humidity values ​​to the main control module for data storage and processing. Simultaneously, the main control module identifies the air conditioner's current operating mode to distinguish between cooling and non-cooling modes. In non-cooling mode, the compressor does not activate the cooling cycle, including normal operating conditions such as heating, fan operation, and dehumidification standby. Based on the real-time collected ambient humidity data and the identified operating mode, the main control module calculates the most suitable power supply voltage value for the current environment according to its set calculation logic. Using this voltage value as a standard, the main control module sends a corresponding voltage output control command to the voltage regulation module. Upon receiving this command, the voltage regulation module quickly adjusts the output voltage, delivering a precisely controlled voltage to the ion generator. An ion generator that operates under a stable and precise power supply voltage can stably output positive and negative ions, and achieve purification treatments such as sterilization, deodorization, and sedimentation of suspended particulate matter in indoor air through the stable output of positive and negative ions.

[0025] For example: The humidity detection module uses an integrated digital temperature and humidity sensor. This type of sensor can simultaneously collect ambient temperature and relative humidity parameters. The sensor communicates with the air conditioner's main control module via an IIC communication bus. The sensor is fixedly installed behind the air inlet filter of the indoor unit, ensuring accurate measurement of the true temperature and humidity of the circulating air flowing through the unit. This significantly reduces the probability of data distortion caused by localized moisture buildup within the air conditioner casing. The main control module can be a high-performance microcontroller. The adaptive voltage regulation program corresponding to this control system can be pre-programmed into the microcontroller's control program, eliminating the need for an additional control board. The voltage regulation module can be a DC-DC (Direct Current to Direct Current) step-down voltage regulator module with an integrated PWM (Pulse Width Modulation) driver chip. The input of this module is connected to the air conditioner's internal 12V DC power supply, and its output is electrically connected to the power supply pin of the ion generator. When the air conditioner's main control module sends PWM pulse signals with different duty cycles, the voltage regulation module can output a steplessly adjustable and continuously smooth voltage within the range of 6V to 12V. The ion generator can be a bipolar positive and negative ion generating device with a carbon fiber discharge needle structure. This bipolar positive and negative ion generating device internally incorporates a high-frequency step-up transformer. The input DC voltage is stepped up by the transformer and converted into a high-voltage output voltage. The input voltage and the boosted output high voltage have a fixed direct proportional conversion relationship. If the step-up transformer ratio is set to 500 times, then under normal operating conditions, the corresponding output high voltage for an input voltage range of 4V to 12V should be within the range of 2KV to 6KV.

[0026] Air conditioners typically operate in cooling, heating, and ventilation modes. The non-cooling operation mode described in this application is not an actual mode set by the air conditioner, but rather a general term used to distinguish it from other operation modes; it is not a specific operating mode. In other words, the cooling and non-cooling operation modes described in this application are distinguished based on whether the air conditioner's refrigeration system is operating and the refrigerant flow direction and phase change characteristics. For example, since the air conditioner is also operating in cooling mode during dehumidification, this application considers dehumidification mode as a cooling operation mode. Conversely, the ventilation mode, where the refrigeration system neither cools nor heats, is considered a non-cooling operation mode in this application.

[0027] When the air conditioner is in non-cooling operation mode, the compressor does not start the cooling cycle. At this time, the temperature and humidity sensor located at the air inlet will collect the ambient humidity data in real time and continuously upload it to the main control microcontroller. The main control microcontroller will simultaneously identify the air conditioner's current operating mode and calculate the target power supply voltage by combining the humidity value and operating mode parameters. Then, it will output a PWM control waveform with the corresponding duty cycle to the DC-DC step-down voltage regulation module. The voltage regulation module will adjust the output voltage in real time according to the PWM instructions, and finally control the ion generator to discharge in the voltage environment that best matches the current ambient humidity and the air conditioner's operating mode, so as to achieve a stable output of positive and negative ions.

[0028] When the air conditioner is in cooling mode, the compressor starts the cooling cycle, and condensation continuously forms on the evaporator surface. After vaporization, this condensation remains inside the air conditioner casing, creating a high-humidity environment. A large amount of water vapor easily adheres to the carbon fiber discharge needles of the ion generator. As ambient humidity increases, air resistivity decreases. When the air conditioner's main control module detects the cooling mode, it actively reduces the supply voltage to the ion generator under the same humidity conditions, lowering the discharge high voltage. This reduces the probability of abnormal breakdown discharges between electrodes and between the electrodes and the air conditioner casing. This prevents negative consequences such as abnormal sparking, operating noise, inter-electrode discharge, and electrode corrosion caused by excessive water vapor adhering to the electrodes, even in high-humidity environments or in cooling mode. When the air conditioner switches to non-cooling mode, the ambient humidity gradually decreases, and the main control module gradually increases the supply voltage accordingly, ensuring the ion generator maintains high ion release efficiency. This achieves a balance between air purification performance and air conditioner operational safety.

[0029] The control method proposed in this embodiment can dynamically adjust the input power supply voltage of the ion generator based on two parameters: real-time ambient humidity data and the air conditioner's operating mode. This allows for the regulation of the ion generator's discharge high voltage value. This control method can reduce the discharge risk by actively lowering the voltage under harsh conditions such as high humidity and excessive condensate, and can also raise the voltage under normal low humidity conditions to ensure ion release and air purification effects. It eliminates operational safety hazards caused by abnormal discharge in the air conditioner, extends the service life of the ion generator electrodes and related components, and ensures that the air conditioner maintains efficient sterilization, deodorization, and air purification performance throughout its entire operating cycle. The air conditioner can autonomously match key parameters dynamically based on the current environment and operating mode without manual intervention, thus significantly improving user safety and experience in daily use.

[0030] like Figure 2As shown, optionally, in one implementation of this embodiment, the air conditioner operating mode includes a cooling operating mode and a non-cooling operating mode; The step of controlling and adjusting the power supply voltage of the ion generator according to the ambient humidity value and the air conditioner's operating mode includes: in any operating mode, the higher the ambient humidity value, the lower the power supply voltage of the ion generator.

[0031] In this embodiment, under the condition that the current operating mode of the air conditioner remains unchanged, when the humidity value data collected from the environment continues to increase, the main control module will issue a control command to control the voltage regulation module to reduce the power supply voltage supplied to the ion generator, so as to realize the dynamic adjustment of the power supply voltage of the ion generator.

[0032] As the humidity level gradually increases, the air conditioner's main control module dynamically lowers the power supply voltage of the ion generator in sync with the humidity change. This voltage reduction also lowers the discharge high voltage generated at the ion generator's downstream end, weakening the electric field strength around the electrodes. This ensures that the electric field strength remains low even as air insulation deteriorates and the critical air breakdown voltage decreases. This control method keeps the electrode high voltage consistently below the critical air breakdown voltage at the current humidity level, preventing abnormal discharge and sparking caused by high-voltage breakdown. It also eliminates the associated operating noise. As the ambient humidity continues to decrease, the air's insulation resistivity rises, and the critical air breakdown voltage increases accordingly. During this process, the air conditioner's main control module gradually increases the power supply voltage to raise the discharge high voltage of the ion generator, gradually restoring it to its rated ion release voltage. This ensures sufficient positive and negative ions are generated, preventing performance degradation during long-term low-voltage operation and maintaining efficient air purification, sterilization, and odor removal.

[0033] In one embodiment, the humidity value under the same operating mode can be divided into three humidity ranges with different control slopes. The internal voltage of different humidity ranges will decrease at different rates as the humidity increases. For example, the low humidity safety range will have a slow voltage reduction, the medium humidity warning range will have an accelerated voltage reduction, and the high humidity high-risk range will have a rapid voltage reduction. In other words, in the low humidity stage, the control system will prioritize ensuring the output voltage and purification performance of the ion generator. When the humidity exceeds the warning range threshold, the control system will accelerate the voltage reduction to prioritize the safe operation of the air conditioner. This way, the ion release efficiency can be preserved to the maximum extent in a dry and low humidity environment, and the high voltage can be quickly reduced in high humidity and harsh operating conditions to reduce the discharge failure rate.

[0034] This control method uses dynamic voltage adjustment, where the power supply voltage decreases as the humidity level increases. This allows the discharge voltage of the ion generator to be dynamically matched with the current air insulation performance, enabling voltage reduction to prevent discharge in high humidity environments and voltage increase to ensure air purification in low humidity environments. This allows the air conditioner to operate efficiently and safely under different conditions.

[0035] like Figure 3 As shown, optionally, in one implementation of this embodiment, the air conditioner operating mode includes a cooling operating mode and a non-cooling operating mode; The step of controlling and adjusting the power supply voltage of the ion generator according to the ambient humidity value and the air conditioner operating mode includes: when the acquired ambient humidity value is the same, controlling the power supply voltage of the ion generator to be V1 in the cooling operation mode and controlling the power supply voltage of the ion generator to be V2 in the non-cooling operation mode, wherein V1 and V2 satisfy: V1 < V2.

[0036] In this embodiment, when the humidity value collected in real time in the current environment is stable and unchanged, if the air conditioner receives a command to switch to the cooling operation mode, the air conditioner main control module will control the voltage regulation module to output a voltage of value V1 to the ion generator. If the air conditioner receives a command to switch to the non-cooling operation mode, the main control module will control the voltage regulation module to output a voltage of value V2 to the ion generator. Since a lot of condensed water vapor will be generated in the cooling operation mode to form a high humidity environment, the voltage value of V1 is set to be less than the voltage value of V2.

[0037] When an air conditioner is turned on in cooling mode, the compressor inside starts the cooling cycle, and low-temperature refrigerant is introduced into the evaporator pipes. When the circulating air in the room passes over the surface of the low-temperature evaporator, the water vapor in the air condenses into water. Some of the condensate is discharged from the air conditioner's drain pan, while some of the less dense water mist and vapor drift and adhere to the surface of the discharge electrodes of the ion generator and the surface of the surrounding parts. When the electrode surface is wet, the local conductivity of its tip is greatly increased, making it easier to break down the surrounding air and cause a discharge fault. Even if the overall indoor humidity does not change, the condensate inside the air conditioner casing will still put the electrode surface in a locally high humidity condition, thus causing abnormal sparking. When the air conditioner is turned on in non-cooling mode, the evaporator does not produce low-temperature condensation, and there is no risk of condensate adhering to the electrode surface of the ion generator. Therefore, under the same ambient humidity, the upper limit of the rated voltage for safe operation of the air conditioner can be higher.

[0038] In one embodiment, the humidity value is divided into three humidity ranges with different control slopes. The pressure difference between V1 and V2 is set to 1V in the low humidity normal range, 2V in the medium humidity warning range, and 3V in the high-risk high humidity range. The higher the humidity value, the more serious the discharge hazard caused by condensate. Therefore, it is necessary to simultaneously increase the voltage difference between cooling and non-cooling. Different humidity values ​​are matched with the corresponding voltage drop amplitude, so that the air conditioner can prioritize retaining purification capacity in low humidity environment with small pressure difference and prioritize ensuring safety in high humidity environment with large pressure difference.

[0039] In another embodiment, under any equal humidity value, the input voltage V1 corresponding to the cooling mode is set to be 2V lower than that of the non-cooling mode V2. That is, in any humidity range, the voltage difference between V1 and V2 is constant at 2V. This simplifies the control logic, reduces the probability of program errors, and improves the response speed of the air conditioner when switching operating conditions.

[0040] In this control method, the power supply voltage V1 in cooling mode is set to be lower than the power supply voltage V2 in non-cooling mode. This can actively reduce the input voltage of the ion generator and lower its downstream discharge high voltage when the air conditioner is in cooling mode, thereby reducing the risk of arcing at the electrode tip and corrosion of parts. After the air conditioner switches back to non-cooling mode, the power supply voltage is actively increased to V2 to control the ion generator to restore a higher discharge voltage, ensuring sufficient ion release efficiency and always matching the best purification effect to the current environment.

[0041] Optionally, in one implementation of this embodiment, such as Figure 4 As shown, the air conditioner's operating modes include a cooling operating mode; The step of controlling and adjusting the power supply voltage of the ion generator according to the ambient humidity value and the air conditioner operating mode includes: controlling and adjusting the power supply voltage of the ion generator according to the following formula; In cooling operation mode, and the ambient humidity value H is within the first preset humidity value range: V1 = V 01 -H×S1; In cooling operation mode, and the ambient humidity value H is within the second preset humidity range: V1 = V 02 -(HH) 1最大 )×S2; In cooling operation mode, and the ambient humidity value H is within the third preset humidity range: V1 = V 03 -(HH) 2最大 )×S3; Wherein, V1 is the power supply voltage for controlling and adjusting the ion generator in the cooling operation mode, V 01V is the preset voltage value corresponding to the first preset humidity range in the cooling operation mode. 02 V is the preset voltage value corresponding to the second preset humidity range in the cooling operation mode. 03 S1 is the preset voltage value corresponding to the third preset humidity range in the cooling operation mode, and H is the coefficient corresponding to the first preset humidity range in the cooling operation mode. 1最大 H is the maximum value within the first preset humidity range. 2最大 S2 is the maximum value in the second preset humidity range, S3 is the coefficient corresponding to the second preset humidity range in the cooling operation mode, and S4 is the coefficient corresponding to the third preset humidity range in the cooling operation mode. The maximum value of the first preset humidity range is less than or equal to the minimum value in the second preset range, and the maximum value of the second preset range is less than or equal to the minimum value in the third preset range; V 01 <V 02 <V 03 S1 < S2 < S3.

[0042] In this embodiment, under cooling conditions, three non-overlapping humidity ranges with progressively increasing intervals are set, and the target supply voltage V1 is obtained by applying the linear calculation formula corresponding to the cooling operation mode. Under non-cooling conditions, the same three non-overlapping humidity ranges with progressively increasing intervals are set, and the target supply voltage V2 is obtained by applying the linear calculation formula corresponding to the non-cooling operation mode. These three humidity ranges are the first preset humidity value range, the second preset humidity value range, and the third preset humidity value range, respectively. The values ​​of these three humidity ranges gradually increase from low to high. Therefore, under each operating condition, the reference initial voltage corresponding to each humidity zone also increases step by step, and the voltage drop coefficient corresponding to each humidity zone also increases step by step.

[0043] Indoor humidity is divided into three continuously increasing and non-overlapping humidity zones: low humidity safe zone, medium humidity warning zone, and high humidity high-risk zone. As the humidity value increases, the insulation performance of the air in the environment will continue to deteriorate, and the critical value of air breakdown voltage will continue to decrease, leading to an increased risk of air conditioner discharge failure.

[0044] Furthermore, the air conditioner's operating mode includes a non-cooling operating mode; The step of controlling and adjusting the power supply voltage of the ion generator based on the ambient humidity value and the air conditioner's operating mode includes: In non-cooling operation mode, and the ambient humidity value H is within the first preset humidity value range: V2 = V 04 -H×S4; In non-cooling operation mode, and the ambient humidity value H is within the second preset humidity range: V2 = V 05 -(HH) 1最大 )×S5; In non-cooling operation mode, and the ambient humidity value H is within the third preset humidity value range: V2 = V 06 -(HH) 2最大 )×S6; Wherein, V2 is the power supply voltage for controlling and adjusting the ion generator in non-cooling operation mode, V 04 V is the preset voltage value corresponding to the first preset humidity range in non-cooling operation mode. 05 V is the preset voltage value corresponding to the second preset humidity range in non-cooling operation mode. 06 S4 is the preset voltage value corresponding to the third preset humidity range in the non-cooling operation mode, and H is the coefficient corresponding to the first preset humidity range in the non-cooling operation mode. 1最大 H is the maximum value within the first preset humidity range. 2最大 S5 is the maximum value in the second preset humidity range, S6 is the coefficient corresponding to the second preset humidity range in the non-cooling operation mode, and S5 is the coefficient corresponding to the third preset humidity range in the non-cooling operation mode. V 04 <V 05 <V 06 S4 < S5 < S6.

[0045] This control method sets progressively increasing voltage reduction coefficients for continuously increasing humidity ranges, i.e., S1 < S2 < S3, S4 < S5 < S6. This ensures that the higher the threshold of the humidity range, the greater the voltage drop per unit increase in humidity. Within the low-humidity safe range, this method performs a slow, small voltage reduction to maintain the current operating voltage of the ion generator and high ion release efficiency, ensuring the air purification capability of the air conditioner in normal dry environments. When the humidity value enters the medium-humidity warning range, the control system accelerates the voltage reduction rate, reserving a safe voltage level in advance to prevent instantaneous breakdown and sparking caused by a rapid increase in humidity. When the humidity value reaches the high-humidity, high-risk range, the control system uses the maximum voltage reduction slope to rapidly lower the supply voltage, minimizing the risk of discharge in extreme high-humidity environments. The reference voltage for each humidity range is set to V. 01 <V 02 <V 03 , and V 04 <V 05 <V 06The system employs the lowest initial reference voltage in the low-humidity safe zone and the highest initial reference voltage in the high-humidity, high-risk zone. This results in a moderate initial reference voltage and slow voltage drop in the low-humidity safe zone, and a higher initial reference voltage but with a significant voltage drop in the high-humidity, high-risk zone. Combining a progressively increasing reference voltage with a progressively increasing voltage drop coefficient adapts to the different risks associated with these three continuously increasing humidity zones. This provides tiered safety protection while also causing a tiered reduction in the air conditioner's purification performance. With the cooling mode voltage value V1 consistently lower than the non-cooling mode voltage value V2 at the same humidity, the air conditioner can automatically compensate for the greater discharge risk caused by condensate in cooling mode, eliminating the need for additional judgment procedures and simplifying the main control program's calculation steps.

[0046] The ion generator boosts the input voltage to high voltage using a high-frequency transformer. Because the turns ratio of the high-frequency transformer is fixed, the input voltage is directly proportional to the output high voltage. The boost factor can be 500 or any value within the range of 400 to 800. The power supply voltage and output high voltage data under different humidity levels and operating modes are shown in the table below:

[0047] For example: The first preset humidity range is the low-humidity safety range, with a humidity value range of 0 ≤ H ≤ 60%RH (Relative Humidity). The second preset humidity range is the medium-humidity warning range, with a humidity value range of 60 < H ≤ 90%RH. The third preset humidity range, also known as the high-humidity high-risk range, is 90 < H ≤ 100%RH. In cooling mode: V 01 =10V, V 02 =9V、V 03 =6V, S1=1 / 60, S2=1 / 10, S3=2 / 5; In non-cooling mode: V 04 =12V, V 05 =11V、V 06 =8V, S4=1 / 60, S5=1 / 10, S6=2 / 5. In the low humidity range, the voltage decreases by 1 / 60V for every 1% increase in RH; in the medium humidity range, the voltage decreases by 0.1V for every 1% increase in RH; and in the high-risk range, the voltage decreases by 0.4V for every 1% increase in RH. This parameter setting is suitable for the indoor environment of a typical household air conditioner. Under this parameter setting, in an indoor environment with the same humidity level, the air conditioner's voltage in cooling mode is consistently 2V lower than its voltage in non-cooling mode, thus offsetting the discharge hazard caused by condensate and achieving graded protection for the air conditioner.

[0048] By setting three progressively increasing humidity ranges and obtaining the target power supply voltage through corresponding linear calculation formulas under different operating conditions, the control system has the ability to automatically adjust the power supply voltage in stages. It achieves differentiated voltage reduction rates for different risks corresponding to different environments, thus ensuring safe operation of the air conditioner across the entire humidity range and enabling the air conditioner to achieve the best air purification effect under the current environment.

[0049] Optionally, in one implementation of this embodiment, the V 01 V 04 V 02 V 05 V 03 V 06 Satisfy: V 01 <V 04 V 02 <V 05 V 03 <V 06 ; In this embodiment, the reference voltage of the first preset humidity range in the cooling mode is less than the reference voltage of the first preset humidity range in the non-cooling mode, the reference voltage of the second preset humidity range in the cooling mode is less than the reference voltage of the second preset humidity range in the non-cooling mode, and the reference voltage of the third preset humidity range in the cooling mode is less than the reference voltage of the third preset humidity range in the non-cooling mode.

[0050] Within the same preset humidity range, the reference voltage in cooling mode is lower than that in non-cooling mode. This allows the ion generator's input voltage to be actively reduced and its downstream discharge high voltage to be lowered when the air conditioner is in cooling mode, thus reducing the risk of arcing at the electrode tip and corrosion of parts. After the air conditioner switches back to non-cooling mode, the power supply voltage is actively increased to control the ion generator to restore a higher discharge voltage, ensuring sufficient ion release efficiency and always matching the best purification effect to the current environment.

[0051] Optionally, in one implementation of this embodiment, S1, S4, S2, S5, S3, and S6 satisfy: S1 = S4, S2 = S5, and S3 = S6.

[0052] In this embodiment, the voltage drop coefficients corresponding to each humidity range in the cooling mode are in a one-to-one correspondence with the voltage drop coefficients of the same humidity range in the non-cooling mode. That is, S1 equals S4 in the first preset humidity range, S2 equals S5 in the second preset humidity range, and S3 equals S6 in the third preset humidity range. For example, S1=S4=1 / 60, S2=S5=1 / 10, and S3=S6=2 / 5.

[0053] Within the same humidity range, regardless of whether the air conditioner is operating in cooling or non-cooling mode, for every fixed unit increase in ambient humidity, the supply voltage decreases synchronously and consistently, ensuring that the rate of change of supply voltage and humidity is uniform. In both cooling and non-cooling modes, the difference in the reference voltage alone is enough to differentiate the final output voltages V1 and V2. The air conditioner's main control module does not need to store six different coefficients separately for cooling and non-cooling modes; instead, it only needs to pre-store three sets of voltage reduction coefficients within the program. This simplifies the control program, and the identical slope of change within the same humidity range ensures that the voltage-humidity curves completely overlap in both cooling and non-cooling modes, with only a fixed vertical voltage difference. This facilitates the standardized calibration of the humidity-voltage correspondence curves during the pre-shipment testing phase of the air conditioner.

[0054] By setting the voltage drop coefficient to be equal in the same humidity range for both cooling and non-cooling modes, the control system can automatically compensate for the voltage difference in power supply to reduce the cooling voltage by utilizing the difference in reference voltage, thereby improving the intelligence level of the air conditioner.

[0055] Optionally, in one implementation of this embodiment, such as Figure 5 As shown, the control method further includes: monitoring whether there are any abnormalities in the voltage and / or current values ​​of the ion generator; and executing an abnormality handling strategy if there are abnormalities. The abnormality handling strategy includes: assigning the ambient humidity value H to H', where H' > H, and adjusting the power supply voltage of the ion generator according to H'.

[0056] In this embodiment, the monitoring module is electrically connected to the air conditioner's main control module and the ion generator, respectively. The monitoring module can collect the working voltage and current data of the ion generator in real time, and compare the collected voltage and current values ​​with the system's preset normal thresholds in real time. Once the monitoring module detects that either the voltage or current value exceeds the normal threshold, such as the current peak value exceeding twice the preset value, it indicates a potential discharge hazard. The monitoring module will then automatically determine that the air conditioner is malfunctioning and transmit the abnormal signal to the air conditioner's main control module. After receiving the abnormal signal, the air conditioner's main control module will automatically start the subsequent fault handling procedure.

[0057] In the instantaneous event of electrode arcing or abnormal discharge faults in the ion generator, the operating current in the circuit will experience a momentary spike pulse, and the equivalent impedance of the load will suddenly change, causing abnormal fluctuations in the supply voltage. The monitoring module monitors the voltage and current parameters of the ion generator in real time around the clock, and can capture the characteristic signals of voltage or current abnormalities at the first moment of a sudden fault. This allows the control system to take proactive remedial measures after a fault occurs, combining pre-fault adaptive dynamic voltage regulation with fault handling procedures to form a dual safety protection system, further reducing the probability of arcing, leakage damage to components, and other situations. After receiving an abnormal signal, the air conditioner's main control module will automatically start the fault handling procedure, without requiring manual intervention throughout the entire fault handling process.

[0058] By monitoring the voltage and current parameters of the ion generator in real time, the control system can take proactive remedial measures after a fault occurs. The combination of pre-fault adaptive dynamic voltage regulation and fault handling procedures forms a dual safety protection system, which further improves the safety of air conditioner operation.

[0059] The abnormal handling strategy includes: assigning the humidity value H to H', where H' > H, and the air conditioner main control module controls the voltage regulation module to supply voltage to the ion generator according to H'.

[0060] In this embodiment, when the air conditioner main control module receives an abnormal signal transmitted by the monitoring module, the air conditioner main control module will automatically modify the humidity calculation value participating in the voltage calculation formula, use a virtual humidity value H' that is larger than the real-time collected humidity value H to replace the original humidity value H in the segmented calculation formula, and recalculate the target power supply voltage with the new H' value as the standard, and control the voltage regulation module to output the power supply voltage with the lower voltage value obtained by recalculation as the standard.

[0061] For example, a fixed 10% RH is added to the real-time humidity value, i.e., H' = H + 10. This 10% RH addition can be achieved through addition, multiplication, or other algorithmic methods. For instance, if the real-time humidity value is 60%, adding 10% results in a virtual humidity value H' of 70%, or vice versa. Adding a fixed humidity value simplifies the calculation logic, and each fault is addressed by a fixed voltage reduction, ensuring a stable and controllable voltage drop. When abnormal current or voltage values ​​appear in the air conditioner's circuits, it indicates that the electrodes are on the verge of discharge under current operating conditions, posing a risk of arcing. Under the H' > H processing logic, the air conditioner's main control module reduces the supply voltage, thus lowering the possibility of electrode arcing.

[0062] By increasing the virtual humidity value to reduce the power supply voltage, the input voltage of the ion generator can be further reduced, causing the high voltage of the discharge at the back end to drop synchronously. This controls the electrode high voltage away from the critical value of discharge breakdown, significantly improving the success rate of handling abnormal discharge faults. Throughout the process, there is no need to manually adjust the hardware structure; the power supply voltage can be reduced urgently simply by relying on the algorithm to virtually increase the humidity value. This improves the response speed of fault handling and further enhances the intelligence of the control system.

[0063] Optionally, in one implementation of this embodiment, such as Figure 5 As shown, the exception handling strategy is repeatedly executed. After each execution of the exception handling strategy, it is determined whether the exception information exists. If the exception information does not exist, the exception handling strategy is stopped and the ion generator is controlled to operate at the current power supply voltage. If the exception information still exists after a preset time, the power supply to the ion generator is cut off. The abnormal information includes the current value of the ion generator exceeding the preset current value.

[0064] In this embodiment, the air conditioner's main control module can repeatedly perform virtual humidity value adjustment. After each virtual humidity value adjustment, the main control module immediately receives real-time voltage and current parameter signals from the monitoring module to determine whether the fault has disappeared. If the fault has disappeared, the virtual humidity will not be increased, and the system will continue to operate at the current output voltage. If the fault persists after multiple virtual humidity value adjustments, the main control module will issue a power-off command after the processing time exceeds a preset waiting time limit, controlling the voltage regulation module to directly cut off the power supply to the ion generator.

[0065] Repeatedly executing the virtual humidity value adjustment and voltage reduction can achieve a step-by-step continuous voltage reduction, causing the voltage to gradually decrease and continuously lowering the discharge high voltage. This can greatly prevent the purification function from failing due to direct power outage. If the fault cannot be eliminated after multiple rounds of continuous voltage reduction, it means that the ion generator has suffered hardware damage. Continuing to power on it at this time will pose a significant risk of leakage and fire. Therefore, the timed power-off control logic can prevent safety accidents caused by forcibly powering on damaged components, thus taking into account both fault recovery and safety protection.

[0066] In this embodiment, the monitoring module collects the working circuit current of the ion generator in real time. When the measured current value of the circuit is greater than the rated safe current threshold preset by the air conditioner main control module, the monitoring module will generate an abnormal signal and send it to the air conditioner main control module.

[0067] When the electrodes of the ion generator experience tip sparking, inter-electrode arcing, or electrode-to-plastic shell creeping discharge, the discharge arc will instantly lower the equivalent load impedance of the circuit, causing the operating current of the power supply circuit to surge sharply, far exceeding the rated operating current limit of the equipment. Using the current exceeding the standard as the core abnormal judgment condition can accurately capture most discharge faults, enabling the control system to quickly identify sparking discharge faults and execute the corresponding program.

[0068] Example 2 This embodiment provides an electronic device, including: a memory for storing computer instructions; A processor is used to invoke and execute the computer instructions to implement the control method in Embodiment 1.

[0069] The electronic device in this embodiment has all the beneficial effects of the control method in Embodiment 1, and will not be described again.

[0070] Example 3 like Figure 6 , 7 As shown, this embodiment provides an air conditioner that executes the control method in Embodiment 1, or includes the electronic device in Embodiment 2; The air conditioner includes: an air conditioner main control module, a humidity detection module and a voltage regulation module electrically connected to the air conditioner main control module, and an ion generator electrically connected to the voltage regulation module; The air conditioner main control module receives the ambient humidity value detected by the humidity detection module, and controls the voltage regulation module to adjust the power supply voltage of the ion generator according to the ambient humidity value and the air conditioner operating mode.

[0071] In this embodiment, the air conditioner includes a control system comprised of an air conditioner main control module, a humidity detection module, a voltage regulation module, and an ion generator. This control system dynamically adjusts the input power supply voltage of the ion generator based on real-time environmental humidity data and the air conditioner's operating mode, thereby regulating the discharge high voltage value of the ion generator. This control system can reduce the risk of discharge by actively lowering the voltage in harsh conditions such as high humidity and excessive condensate, and can also raise the voltage in normal low-humidity conditions to ensure ion release and air purification effects. This eliminates operational safety hazards caused by abnormal discharge, extends the service life of the ion generator electrodes and related components, and ensures that the air conditioner maintains efficient sterilization, deodorization, and air purification performance throughout its entire operating cycle. The air conditioner can autonomously match key parameters dynamically based on the current environment and operating mode without manual intervention, significantly improving user safety and experience in daily use.

[0072] It should be noted that in this embodiment, the air conditioner ion generator is in a closed state after the air conditioner is turned off, as the control system stops working.

[0073] In summary, the ingenious design of this control method lies in: First, the input power supply voltage of the ion generator can be dynamically adjusted based on real-time environmental humidity data and the air conditioner's operating mode, thereby regulating the discharge high voltage value of the ion generator. This control system can reduce the risk of discharge by actively lowering the voltage in harsh conditions such as high humidity and excessive condensate, and can also raise the voltage in normal low humidity conditions to ensure ion release and air purification effects. This eliminates operational safety hazards caused by abnormal discharge in the air conditioner, extends the service life of the ion generator electrodes and related components, and ensures that the air conditioner maintains efficient sterilization, deodorization, and air purification performance throughout its entire operating cycle. The air conditioner can autonomously match key parameters dynamically based on the current environment and operating mode, without any manual intervention, thus significantly improving user safety and experience in daily use.

[0074] Secondly, under the same operating conditions, the dynamic voltage adjustment, which reduces the power supply voltage as the humidity value increases, enables the discharge voltage of the ion generator to dynamically match the current air insulation performance. This achieves voltage reduction to prevent discharge in high humidity environments and voltage increase to ensure air purification in low humidity environments, allowing the air conditioner to operate efficiently and safely under different operating conditions.

[0075] Third, setting the power supply voltage V1 in cooling mode to be lower than the power supply voltage V2 in non-cooling mode can actively reduce the input voltage of the ion generator and lower its downstream discharge high voltage when the air conditioner is in cooling mode, thereby reducing the risk of arcing at the electrode tip and corrosion of parts. After the air conditioner switches back to non-cooling mode, the power supply voltage is actively increased to V2 to control the ion generator to restore a higher discharge voltage, ensuring sufficient ion release efficiency and always matching the best purification effect to the current environment.

[0076] Fourth, by setting three progressively increasing humidity ranges and obtaining the target power supply voltage through corresponding linear calculation formulas under different operating conditions, the control system has the ability to automatically adjust the power supply voltage in stages. It achieves differentiated voltage reduction rates for different risks corresponding to different environments, thus ensuring safe operation of the air conditioner across the entire humidity range and enabling the air conditioner to achieve the best air purification effect under the current environment.

[0077] Fifth, by setting the voltage drop coefficient to be equal in the same humidity range for both cooling and non-cooling conditions, the control system can automatically compensate for the voltage difference in power supply for cooling voltage drop by utilizing the difference in reference voltage, thereby improving the intelligence level of the air conditioner.

[0078] Sixth, by monitoring the voltage and current parameters of the ion generator in real time, remedial measures can be taken proactively after a fault occurs. The combination of pre-fault adaptive dynamic voltage regulation and fault handling procedures forms a dual safety protection system, further enhancing the safety of air conditioner operation.

[0079] Seventh, by increasing the virtual humidity value to reduce the power supply voltage, the input voltage of the ion generator can be further reduced, causing the discharge high voltage at the back end to drop synchronously. This controls the electrode high voltage away from the critical value of discharge breakdown, significantly improving the success rate of handling abnormal discharge faults. Throughout the process, there is no need to manually adjust the hardware structure; the power supply voltage can be reduced urgently simply by relying on the algorithm to virtually increase the humidity value. This improves the response speed of fault handling and further enhances the intelligence level of the control system.

[0080] Eighth, the repeated execution of virtual humidity value raising and lowering voltage can achieve step-by-step continuous voltage reduction, so that the voltage continues to decrease step by step, constantly lowering the discharge high voltage. This is very likely to avoid the failure of the purification function caused by direct shutdown and power cut-off. If the fault still cannot be eliminated after multiple rounds of continuous voltage reduction, it means that the ion generator has suffered hardware damage. At this time, continuing to power on will pose a significant risk of leakage and fire. Therefore, the timed power-off control logic can avoid safety accidents caused by forcibly powering on damaged components, taking into account both fault rescue and safety protection.
