Other auxiliary modules in the indoor unit, such as electric heating devices and air purification devices, are installed in other fixed positions on the indoor unit. Thus, when these auxiliary modules are working, the cross-flow fan and the auxiliary modules operate independently, resulting in uneven performance of the auxiliary modules. This can lead to problems such as uneven air heating and inconsistent air purification.

[0006] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art. Summary of the Invention

[0007] To provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. This summary is not intended as a general commentary, nor is it intended to identify key / important components or describe the scope of protection of these embodiments, but rather as a prelude to the detailed description that follows.

[0008] This disclosure provides a control method, control device, air conditioner, and storage medium for an air conditioner cross-flow fan, so as to meet the negative ion concentration requirements in different scenarios while ensuring purification effect.

[0014] In this embodiment, the negative ion generator is placed inside the cross-flow fan, and the diffusion of negative ions is affected by the fan's rotation speed. Simultaneously, because negative ions increase the cooling sensation on the human body, they can influence indoor air comfort while purifying the air. Therefore, the target voltage of the negative ion generator is determined based on the air conditioner's operating mode, indoor environmental parameters, and the air conditioner's target temperature. This allows the concentration of negative ions to be determined based on the scenario requirements. The target speed of the cross-flow fan is also determined, ensuring that the target concentration of negative ions can be evenly diffused into the indoor air.

[0032] Combination Figure 1 , 2 As shown, the cross-flow fan includes an impeller 10 and a negative ion generator 20. The impeller 10 defines a cavity, and the negative ion generator 20 is disposed within the cavity. The negative ion generator 20 includes a fixed shaft 21 and a plurality of emitters 22. The fixed shaft 21 is disposed within the cavity and coincides with the axis of the impeller 10. Emitters are spaced along the axial direction of the impeller 10 on the fixed shaft 21.

[0033] Optionally, a heating device 30 is provided around the negative ion generator 20, and an air vent 31 is provided on the wall of the heating device 30 so that the negative ions generated by the negative ion generator 20 can flow out from the air vent 31.

[0034] Optionally, both the heating device 30 and the negative ion generator 20 rotate synchronously with the impeller 10. In this way, negative ions and heat can flow with the air to the outside of the impeller 10 to purify and heat the air outside the cross-flow fan. This also helps reduce noise.

[0035] Combination Figure 3 As shown, this disclosure provides a control method for an air conditioner cross-flow fan, including:

[0036] S101, the processor obtains the indoor ambient temperature, humidity and target temperature.

[0037] S102, the processor determines the target voltage of the negative ion generator and the target wind speed of the cross-flow fan based on the air conditioner's operating mode and the indoor ambient temperature, humidity and target temperature.

[0038] S103, the processor controls the negative ion generator to execute the target voltage and the cross-flow fan to execute the target wind speed.

[0039] In this embodiment, the negative ion generator is disposed within the inner cavity of the cross-flow fan impeller. When the negative ion generator produces a fixed concentration of negative ions, different rotational speeds of the cross-flow fan have varying effects on the diffusion of negative ions. Understandably, faster wind speeds result in faster diffusion of negative ions, which helps to distribute them evenly throughout the room. Slower wind speeds result in slower diffusion of negative ions. The speed of negative ion diffusion affects the rate and effectiveness of indoor air purification.

[0040] Meanwhile, the required concentration of negative ions and the ease of their generation vary depending on the indoor temperature and humidity. Generally, higher indoor temperatures accelerate molecular movement and increase intermolecular expansion, which promotes negative ion generation. Negative ions increase the feeling of coolness in the human body, so increasing the concentration of negative ions in low humidity environments can reduce air dryness and increase user comfort. Additionally, appropriately increasing the concentration of negative ions can also help lower the perceived temperature. Furthermore, when the air conditioner is operating in heating mode, higher indoor temperatures and lower humidity can easily lead to static electricity due to higher negative ion concentrations.

[0041] In summary, the concentration of negative ions is affected by multiple parameters mentioned above, and the required concentration varies depending on the scenario. Therefore, the indoor ambient temperature, humidity, and target temperature are obtained. Based on these parameters and the air conditioner's operating mode, the target voltage for the negative ion generator and the target fan speed are determined. The voltage of the negative ion generator determines the concentration of negative ions; the higher the voltage, the higher the concentration. Here, the target temperature and indoor ambient temperature primarily affect the fan speed.

[0042] The control method for an air conditioner cross-flow fan provided in this embodiment places a negative ion generator inside the cross-flow fan, and the diffusion of negative ions is affected by the fan's rotation speed. Simultaneously, because negative ions can increase the cooling sensation for the human body, they can affect indoor air comfort while purifying the air. Therefore, the target voltage of the negative ion generator is determined based on the air conditioner's operating mode, indoor environmental parameters, and the air conditioner's target temperature. This determines the concentration of negative ions based on the scenario requirements. The target speed of the cross-flow fan is also determined, ensuring that the target concentration of negative ions can be evenly diffused into the indoor air. This satisfies the needs of different scenarios when purifying the air.

[0043] Optionally, in step S102, the processor determines the target voltage of the negative ion generator and the target fan speed of the cross-flow fan based on the air conditioner's operating mode and the indoor ambient temperature, humidity, and target temperature, including:

[0044] When the air conditioner is in heating mode, the greater the initial difference between the target temperature and the indoor ambient temperature, the higher the target voltage of the negative ion generator and the higher the target wind speed of the cross-flow fan.

[0045] When the first difference is the same, the higher the indoor humidity, the higher the target voltage of the negative ion generator; or, when the first difference is the same, the higher the indoor temperature, the lower the target voltage of the negative ion generator.

[0046] The target voltage is less than the voltage threshold.

[0047] This section focuses on the control of negative ion concentration in air conditioning heating mode. The first difference between the target temperature Ts and the indoor ambient temperature Tr is ΔT1 = Ts - Tr. When ΔT1 > 0, it indicates that the indoor ambient temperature is lower than the target temperature. In this case, the larger ΔT1 is, the lower the indoor ambient temperature, the higher the target airflow speed of the cross-flow fan, and the higher the target voltage of the negative ion generator. When ΔT1 ≤ 0, it indicates that the indoor ambient temperature is higher than or equal to the target temperature. The smaller ΔT1 is, the higher the indoor ambient temperature is than the target temperature, the lower the target airflow speed of the cross-flow fan, and the lower the target voltage of the negative ion generator. Overall, the target voltage and target airflow speed when ΔT1 > 0 are both greater than those when ΔT1 ≤ 0, and the target voltage is lower than the voltage threshold.

[0048] Understandably, in heating mode, if the indoor ambient temperature is lower than the target temperature, the cross-flow fan will operate at a relatively high speed to quickly raise the indoor temperature. In this case, negative ions are more easily dispersed, but the low indoor temperature is not conducive to negative ion generation. Therefore, the target voltage of the negative ion generator needs to be increased to improve the concentration of negative ions. If the indoor ambient temperature is greater than or equal to the target temperature, the cross-flow fan will operate at a lower speed, or even zero speed. At this time, the negative ions disperse slowly, and the higher indoor temperature makes negative ion generation easier. Therefore, the target voltage of the negative ion generator needs to be reduced. This avoids wasting resources due to insufficient negative ion dispersion and prevents localized high negative ion concentrations from generating static electricity, which would negatively impact the user experience.

[0049] Furthermore, given the same initial difference, the concentration of negative ions depends on the indoor humidity and temperature. Higher indoor humidity requires a lower target voltage from the negative ion generator, thus preventing the cooling effect of negative ions from lowering the user's perceived temperature. Higher indoor temperature also requires a lower target voltage from the negative ion generator, thus preventing excessive negative ions from causing static electricity.

[0050] As an example, at ΔT1=2℃, if Tr=24℃, the target voltage Vr=1 / 3Vs. If Tr=26℃, the target voltage Vr=1 / 4Vs. At ΔT1=2℃, if the indoor ambient humidity Hr=35%, the target voltage Vr=2 / 3Vs. If Hr=55%, the target voltage Vr=1 / 3Vs. Here, the voltage threshold Vs refers to the critical voltage between the heating and cooling modes of the negative ion generator. That is, in heating mode, the target voltage is less than or equal to the critical voltage. In cooling mode, the target voltage is greater than or equal to the critical voltage.

[0051] Optionally, based on the above-determined target voltage and target wind speed, the target voltage and target rotational speed can be determined by looking up a table. The correspondence between the first difference, humidity, indoor ambient temperature, and target voltage and target wind speed is shown in Table 1.

[0052] Table 1

[0053]

[0054] It should be noted that in heating mode, if the indoor ambient temperature, humidity and target temperature do not meet the conditions in Table 1, the target voltage is the voltage threshold and the target speed is the air conditioner's default speed.

[0055] Optionally, in step S102, the processor determines the target voltage of the negative ion generator and the target fan speed of the cross-flow fan based on the air conditioner's operating mode and the indoor ambient temperature, humidity, and target temperature, including:

[0056] When the air conditioner is running in cooling mode and the indoor ambient temperature is higher than the target temperature, the greater the second difference between the indoor ambient temperature and the target temperature, the higher the target voltage of the negative ion generator and the higher the target wind speed of the cross-flow fan.

[0057] When the second difference is the same, the lower the indoor humidity, the higher the target voltage of the negative ion generator; or, when the second difference is the same, the higher the indoor temperature, the higher the target voltage of the negative ion generator.

[0058] The target voltage is greater than or equal to the voltage threshold.

[0059] This section focuses on controlling the concentration of negative ions in air conditioning cooling mode. The second difference between the indoor ambient temperature Tr and the target temperature Ts is ΔT2 = Tr - Ts. When ΔT2 > 0, it indicates that the indoor ambient temperature has not reached the target temperature. In this case, the larger ΔT2 is, the higher the indoor ambient temperature, the higher the target airflow speed of the cross-flow fan, and the higher the target voltage of the negative ion generator.

[0060] Similarly, in cooling mode, if the indoor ambient temperature is higher than the target temperature, the cross-flow fan will run at a relatively high speed to quickly lower the indoor temperature. In this situation, negative ions are more easily dispersed, and the higher indoor temperature also promotes the generation of negative ions. Furthermore, the higher the concentration of negative ions, the more it helps reduce the user's feeling of heat. Therefore, the target voltage of the negative ion generator is relatively high to increase the concentration of negative ions.

[0061] Furthermore, given the same second difference, the negative ion concentration depends on the indoor humidity and temperature. The higher the indoor temperature, the higher the target voltage of the negative ion generator. This increases the negative ion concentration, enhances the cooling effect of the air, and lowers the perceived temperature for the user. Conversely, the lower the indoor humidity, the higher the target voltage of the negative ion generator. This increases the cooling sensation, reduces the dryness of the indoor air, and improves user comfort.

[0062] Optionally, in cooling mode and when the indoor ambient temperature is higher than the target temperature, the target voltage and target fan speed can be determined by looking up a table, based on the target voltage and target fan speed determined above. The correspondence between the second difference, humidity, indoor ambient temperature, and target voltage and target fan speed is shown in Table 2.

[0063] Table 2

[0064]

[0065] In addition, it should be noted that in cooling mode, if the indoor ambient temperature, humidity and target temperature do not meet the conditions in Table 2, the target voltage is the voltage threshold and the target speed is the air conditioner's default speed.

[0066] Optionally, in step S102, the processor determines the target voltage of the negative ion generator and the target fan speed of the cross-flow fan based on the air conditioner's operating mode and the indoor ambient temperature, humidity, and target temperature, and further includes:

[0067] When the indoor ambient temperature is less than or equal to the target temperature, the processor obtains the compressor's status.

[0068] With the compressor running, the processor determines that the target voltage of the negative ion generator is the voltage threshold and the target speed of the cross-flow fan is the minimum speed.

[0069] With the compressor in standby mode, the processor determines that the target voltage of the negative ion generator is the highest operating voltage and the target speed of the cross-flow fan is the highest speed.

[0070] In this embodiment, during air conditioning cooling mode, the compressor will stop and standby when the indoor ambient temperature is less than or equal to the target temperature. Subsequently, the indoor ambient temperature will gradually rise. To slow the rate of temperature increase, while the compressor is in standby mode, the target voltage of the negative ion generator can be adjusted to the highest operating voltage, and the cross-flow fan can run at its highest speed. This slows the rate of temperature increase through a high concentration of negative ions. Furthermore, because the indoor temperature is low, the probability of static electricity generation from the high concentration of negative ions is also low, thus ensuring user comfort. With the compressor running, the indoor ambient temperature can be maintained at a low level. Therefore, the target voltage of the negative ion generator is the voltage threshold (i.e., the minimum target temperature in cooling mode), and the target speed of the cross-flow fan is the lowest speed. The highest operating voltage is 2.5Vs.

[0071] Combination Figure 4 As shown, this disclosure provides another control method for an air conditioner cross-flow fan, including:

[0072] S101, the processor obtains the indoor ambient temperature, humidity and target temperature.

[0073] S102, the processor determines the target voltage of the negative ion generator and the target wind speed of the cross-flow fan based on the air conditioner's operating mode and the indoor ambient temperature, humidity and target temperature.

[0074] S103, the processor controls the negative ion generator to execute the target voltage and the cross-flow fan to execute the target wind speed.

[0075] S204: When the air conditioner is in cooling mode, the processor controls the operating parameters of the electric heating device based on the indoor ambient temperature, humidity, and target temperature.

[0076] Here, when the air conditioner is running in cooling mode, the indoor humidity may be high. When the indoor temperature hasn't dropped to near the target temperature and the humidity is also high, users are prone to feeling stuffy and hot. Therefore, based on the indoor temperature, humidity, and target temperature, the operating parameters of the electric heating device are determined, and the device is controlled accordingly. Turning on the electric heating device helps to quickly reduce humidity and also accelerates the generation and diffusion of negative ions.

[0077] Specifically, when the difference between the indoor ambient temperature and the target temperature is small, and the humidity is high, the electric heating device should be turned on. The heating setting of the electric heating device should also be higher when the humidity is high. Understandably, a small difference between the indoor ambient temperature and the target temperature indicates that the indoor temperature has already decreased. However, the humidity is still high, indicating that the dehumidification effect of the cooling is only average. Therefore, the electric heating device is turned on to dry the humid air. During this process, the heating setting of the electric heating device should be lower than or equal to the medium setting to avoid setting too high and affecting the cooling effect.

[0078] S204, the processor controls the operating parameters of the electric heating device based on the indoor ambient temperature, humidity, and target temperature, including:

[0079] If the second difference between the indoor ambient temperature and the target temperature is greater than the first threshold but less than the second threshold, and the indoor ambient temperature is less than the first temperature, then if the indoor ambient humidity is greater than the first humidity, the processor controls the electric heating device to turn on.

[0080] The processor controls the heating level of the electric heating device based on the indoor humidity.

[0081] In this embodiment, if the second difference satisfies T1 < ΔT2 ≤ T2, it indicates that the difference between the indoor ambient temperature and the target temperature is small. Further, if the indoor ambient temperature is also lower than the first temperature, it indicates that the indoor ambient temperature has decreased to near the target temperature. In this case, if the indoor ambient humidity is greater than the first humidity, it indicates that the dehumidification effect of the air conditioner in cooling mode is generally poor. Therefore, the electric heating device is turned on. The starting temperature of the electric heating device is controlled according to the indoor ambient humidity. The higher the indoor ambient humidity, the higher the heating level of the electric heating device. To avoid the electric heating device affecting the cooling effect, the heating level should not be too high.

[0082] Optionally, the processor controls the heating level of the electric heating device based on the indoor humidity, including:

[0083] When the indoor humidity is greater than the first humidity level but less than the second humidity level, the processor controls the electric heating device to operate at a low setting.

[0084] When the indoor humidity is greater than or equal to the second humidity level, the processor controls the electric heating device to operate at the medium setting.

[0085] Here, the value range of the first humidity Hr1 is 40%-45%, and the value range of the second humidity Hr2 is 60%-65%.

[0086] Combination Figure 5 As shown, this disclosure provides another control method for an air conditioner cross-flow fan, including:

[0087] S101, the processor obtains the indoor ambient temperature, humidity and target temperature.

[0088] S102, the processor determines the target voltage of the negative ion generator and the target wind speed of the cross-flow fan based on the air conditioner's operating mode and the indoor ambient temperature, humidity and target temperature.

[0089] S103, the processor controls the negative ion generator to execute the target voltage and the cross-flow fan to execute the target wind speed.

[0090] S204: When the air conditioner is in cooling mode, the processor controls the operating parameters of the electric heating device based on the indoor ambient temperature, humidity, and target temperature.

[0091] S305, when the second difference between the indoor ambient temperature and the target temperature is greater than the second threshold, or when the indoor ambient humidity decreases to the corresponding humidity threshold, the processor controls the heating level of the electric heating device to decrease to the next level.

[0092] When the current heating level is the lowest level, the next level refers to the power off level.

[0093] As mentioned earlier, when the second difference condition is met, the heating level of the electric heating device is controlled for different humidity zones. Furthermore, corresponding humidity thresholds are set for each humidity zone: when Hr1 < Hr < Hr2, the humidity threshold is Hr1'; when Hr ≥ Hr2, the humidity threshold is Hr2', where Hr2' > ​​Hr1'. Thus, after the electric heating device is activated, the indoor ambient humidity and the second difference are monitored. When the indoor ambient humidity meets the corresponding humidity threshold, it indicates a decrease in indoor humidity. Alternatively, when the second difference is greater than the second threshold, it indicates significant fluctuations in indoor temperature. In both cases, the electric heating device needs to be reduced in level to prevent further fluctuations in indoor temperature. Furthermore, when humidity is high, it remains at a low level to dry the humid air.

[0094] Optionally, in step S204, after the processor controls the operating parameters of the electric heating device based on the indoor ambient temperature, humidity, and target temperature, the process further includes:

[0095] The processor positively corrects the target voltage of the negative ion generator.

[0096] Here, after the electric heating device is turned on, the target voltage of the negative ion generator is increased. On one hand, negative ions also have a certain water-absorbing and moisture-resistant function. On the other hand, increasing the concentration of negative ions helps to increase the cooling sensation, and turning on the electric heating device also facilitates the generation of negative ions. Specifically, the correction range can be determined based on the indoor humidity. For example, the higher the indoor humidity, the larger the correction range. Alternatively, when the indoor humidity is in the first humidity range (Hr1 < Hr < Hr2), the correction range is the first range. When the indoor humidity is in the second humidity range (Hr ≥ Hr2), the correction range is the second range. The first range is smaller than the second range, and the ratio of the second range to the first range is greater than 1.5.

[0097] This disclosure provides a control device for an air conditioner cross-flow fan, including an acquisition module, a determination module, and a control module. The acquisition module is configured to acquire indoor ambient temperature, humidity, and a target temperature. The determination module is configured to determine the target voltage of a negative ion generator and the target fan speed based on the air conditioner's operating mode and the indoor ambient temperature, humidity, and target temperature. The control module is configured to control the negative ion generator to execute the target voltage and the cross-flow fan to execute the target fan speed.

[0098] The control device for an air conditioner cross-flow fan provided in this embodiment incorporates a negative ion generator within the cross-flow fan's interior. The diffusion of negative ions is influenced by the fan's rotational speed. Simultaneously, because negative ions increase the cooling sensation for the human body, they can affect indoor air comfort while purifying the air. Therefore, the target voltage of the negative ion generator is determined based on the air conditioner's operating mode, indoor environmental parameters, and the air conditioner's target temperature. This allows the concentration of negative ions to be determined based on the specific scenario requirements. The target speed of the cross-flow fan is also determined, ensuring that the target concentration of negative ions can be evenly diffused into the indoor air. This, in turn, meets the needs of different scenarios when purifying the air.
