Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of intelligent household appliances, for example to a method and device for controlling an air conditioner air deflector, an air conditioner and a storage medium. BACKGROUND

[0002] An air conditioner is a common device in family life, which can adjust indoor temperature by heating or cooling indoor air. When a user sets the air conditioner to swing air supply, the air deflector is free to swing in the maximum range. When the air conditioner runs in heating mode, the temperature of the indoor coil gradually rises as the indoor temperature rises. At this time, if the air deflector is still free to swing in the maximum range, it will help the coil temperature rise. At this time, the air conditioner will automatically reduce the compressor frequency, the outdoor fan speed, etc., so as not to let the indoor coil temperature rise too fast. This will make the indoor coil temperature drop, but at the same time, it will also make the air conditioner outlet temperature drop.

[0003] The existing method, device and air conditioner for air conditioner heating control, wherein the method comprises: obtaining the current position of the deflector of the air conditioner running in heating mode, wherein the deflector is running in free swing mode; determining the current speed of the indoor fan of the air conditioner corresponding to the current position according to the fact that the air volume of the air conditioner is the same in each position of the deflector; and controlling the heating operation of the air conditioner according to the current speed.

[0004] The above control method ensures the maintenance of air volume by adjusting the speed of the indoor fan, so that the indoor coil temperature is not easy to touch the protection line. However, when the deflector is in a position with large air resistance, increasing the speed of the indoor fan will cause large air noise, thereby affecting the user experience. SUMMARY

[0005] The following presents a simplified summary of some aspects of the disclosed embodiments in order to provide a basic understanding of such embodiments. This summary is not an extensive overview of the embodiments described in detail in the following detailed description, and is not intended to identify key / critical elements of the embodiments or to delineate the scope of the embodiments.

[0006] The embodiments of the present disclosure provide a method, device, air conditioner and storage medium for controlling an air conditioner air deflector, so as to reduce the possibility of large air noise while ensuring heating effect.

[0007] In some embodiments, the method comprises: in the case that the air conditioner runs in heating mode and the air deflector swings freely, obtaining the temperature of the indoor coil; determining the control requirement for the position of the air deflector according to the temperature of the indoor coil and the swing range of the air deflector; and in the case that the control requirement indicates that the position of the air deflector needs to be corrected, correcting the upper limit of the swing of the air deflector.

[0008] In some embodiments, the apparatus comprises a processor and a memory storing program instructions, the processor is configured to execute the foregoing method for controlling the air conditioner air deflector when running the program instructions.

[0009] In some embodiments, the air conditioner comprises the foregoing apparatus for controlling the air conditioner air deflector.

[0010] In some embodiments, the storage medium stores program instructions, the program instructions execute the foregoing method for controlling the air conditioner air deflector when running.

[0011] The method, apparatus, air conditioner and storage medium for controlling the air conditioner air deflector provided by the embodiments of the present disclosure can achieve the following technical effects:

[0012] Based on the current swing range of the air deflector and the real-time temperature of the inner coil, it is determined whether the air deflector has a demand for position correction. If so, the swing upper limit of the air deflector is corrected. The corrected swing range is more conducive to heat dissipation of the inner coil. In this way, the possibility of the air conditioner entering into frequency reduction or shutdown protection due to the temperature of the inner coil being too high is reduced, thereby ensuring the heating effect of the air conditioner. Moreover, the heat dissipation of the inner coil is improved by correcting the swing upper limit of the air deflector, without the need to increase the rotation speed of the fan. In this way, the generation of large wind noise is avoided, and the user experience is improved.

[0031] In the disclosed embodiments, the terminal device refers to an electronic device with wireless connection function. The terminal device can be connected to the smart home appliance through the Internet, or can be directly connected to the smart home appliance through Bluetooth, WiFi, etc. In some embodiments, the terminal device is, for example, a mobile device, a computer, or a built-in vehicle device in a hovercar, etc., or any combination thereof.

[0032] In combination Figure 1 As shown, the disclosed embodiments provide a method for controlling an air conditioner air deflector, comprising:

[0033] S101, the air conditioner obtains the temperature of the inner coil when the air conditioner is running in a heating mode and the air deflector is freely swinging.

[0034] S102, the air conditioner determines the control requirement for the position of the air deflector according to the temperature of the inner coil and the swinging range of the air deflector.

[0035] S103, the air conditioner corrects the upper limit of the swing of the air deflector when the control requirement indicates that the position of the air deflector needs to be corrected.

[0036] The user sends a command of heating and freely swinging air deflector to the air conditioner through the air conditioner remote controller or the terminal device. The air conditioner receives and responds to the command sent by the user. The air conditioner runs in a heating mode, and the air deflector freely swings according to the swinging range set by the user. A temperature sensor is arranged on or near the inner coil of the air conditioner. The air conditioner can obtain the real-time temperature of the inner coil through the temperature sensor. The air deflector is connected with an angle sensor. The air conditioner can obtain the opening angle of the air deflector through the angle sensor, so as to determine the upper limit of the swing of the air deflector. According to the detected swinging range of the air deflector and the temperature of the inner coil, the control requirement for the position of the air deflector is determined, that is, whether the position of the air deflector needs to be corrected. When the control requirement indicates that the position of the air deflector does not need to be corrected, the swinging range of the air deflector remains unchanged. When the control requirement indicates that the position of the air deflector needs to be corrected, the upper limit of the swing of the air deflector is corrected, and the lower limit of the swing of the air deflector remains unchanged. The corrected swinging range is the region between the corrected upper limit of the swing and the initial lower limit of the swing. The air deflector freely swings in the corrected swinging range.

[0037] In the embodiments of the present disclosure, whether the position of the air deflector needs to be corrected is determined based on the current swing range of the air deflector and the real-time temperature of the inner coil. If yes, the swing upper limit of the air deflector is corrected. The corrected swing range is more conducive to heat dissipation of the inner coil. In this way, the possibility of the air conditioner entering into frequency reduction or shutdown protection due to the over-high temperature of the inner coil is reduced, thereby ensuring the heating effect of the air conditioner. Moreover, the heat dissipation of the inner coil is improved by correcting the swing upper limit of the air deflector, without the need to increase the rotating speed of the fan. In this way, the generation of large wind noise is avoided, and the user experience is improved. After the swing upper limit of the air deflector is corrected, the air deflector freely swings in the new swing range. In this way, the will of the user to freely swing the air deflector is not violated, and the demand of the user is fully met.

[0038] In combination Figure 2 The embodiments of the present disclosure provide another method for controlling an air deflector of an air conditioner, which comprises the following steps.

[0039] In S201, the temperature of the inner coil is acquired when the air conditioner is running in a heating mode and the air deflector is freely swinging.

[0040] In S202, the maximum air outlet position of the air conditioner is determined.

[0041] In S203, when the temperature of the inner coil is greater than a first temperature threshold and the included angle between the swing upper limit of the air deflector and the maximum air outlet position is greater than an angle threshold, the air conditioner determines that the control demand is to correct the position of the air deflector.

[0042] In S204, when the temperature of the inner coil is less than or equal to the first temperature threshold, or when the temperature of the inner coil is greater than the first temperature threshold and the included angle between the swing upper limit of the air deflector and the maximum air outlet position is less than or equal to the angle threshold, the air conditioner determines that the control demand is not to correct the position of the air deflector.

[0043] In S205, after S203 is performed, when the control demand indicates that the position of the air deflector needs to be corrected, the swing upper limit of the air deflector is corrected by the air conditioner.

[0044] In S206, after S204 is performed, when the control demand indicates that the position of the air deflector does not need to be corrected, the swing range of the air deflector is not changed by the air conditioner.

[0045] The user sends a heating and freely swinging damper command to the air conditioner through the air conditioner remote controller or terminal device. The air conditioner receives and responds to the user-sent command. The air conditioner runs in the heating mode, and the damper freely swings according to the user-set swinging range. A temperature sensor is arranged on or near the inner coil of the air conditioner. The air conditioner can acquire the real-time temperature of the inner coil through the temperature sensor. An angle sensor is connected to the damper. The air conditioner can acquire the opening angle of the damper through the angle sensor, so as to determine the upper limit of the swinging of the damper.

[0046] The maximum air outlet position of the air conditioner is pre-set when the air conditioner is manufactured. The maximum air outlet position is different for different models. Therefore, the maximum air outlet position matching the model of the air conditioner can be obtained in the manufacturer database. The closer the position of the damper to the maximum air outlet position, the smaller the impedance of the damper to the air outlet of the air conditioner, and the greater the heat dissipation of the inner coil. When the damper is at the maximum air outlet position, the impedance of the damper to the air outlet of the air conditioner is the smallest, and the heat dissipation of the inner coil is the greatest. In the same time length, the greater the included angle between the upper limit of the swinging of the damper and the maximum air outlet position, the longer the time for the damper to swing from the upper limit to the maximum air outlet position, and the fewer the times for the damper to pass through the maximum air outlet position, which is not conducive to the heat dissipation of the inner coil. A set angle threshold is provided. When the included angle between the upper limit of the swinging of the damper and the maximum air outlet position is less than or equal to the angle threshold, it can be considered that the heat dissipation effect of the inner coil reaches the best. Optionally, the angle threshold is 0°-5°. It should be noted that the angle threshold can be determined according to actual needs, and the present embodiment does not make any limitation thereto.

[0047] The temperature of the inner coil is T 内 . A first temperature threshold T m is set. T m is the upper limit of the temperature of the inner coil. If the temperature of the inner coil exceeds T m , the heat dissipation of the inner coil needs to be increased. If T 内 ≤T m , and the included angle between the upper limit of the swinging of the damper and the maximum air outlet position is greater than the angle threshold. At this time, the temperature of the inner coil has exceeded the upper limit, and the upper limit of the swinging of the damper is far away from the maximum air outlet position, which is not conducive to the heat dissipation of the inner coil. In this case, it is determined that the control requirement is to correct the position of the damper to improve the heat dissipation of the inner coil. Then the damper is controlled to freely swing between the corrected upper limit and the initial lower limit. If T 内 ≤T m , it indicates that the temperature of the inner coil does not reach the upper limit at this time, so the position of the damper does not need to be corrected. In this case, it is determined that the control requirement is not to correct the position of the damper. If T 内 >T m, and the included angle between the swing upper limit of the air deflector and the maximum air outlet position is less than or equal to the angle threshold. At this time, the temperature of the inner coil has exceeded the upper limit, but the air deflector is close to the maximum air outlet position, and the air deflection position of the air deflector can make the heat dissipation of the inner coil reach the best state. In this case, the position of the air deflector does not need to be corrected. Therefore, it is determined that the control requirement is not to correct the position of the air deflector. When the position of the air deflector does not need to be corrected, the air deflector remains the current swing upper limit unchanged. In this way, based on the temperature of the inner coil and the position of the air deflector, it is determined in real time whether the position of the air deflector needs to be corrected, which can make the determination result more accurate, thereby more accurately controlling the air deflection position of the air deflector.

[0048] In combination with Figure 3 As shown in the figure, the air conditioner corrects the swing upper limit of the air deflector, including:

[0049] S301, the air conditioner determines its maximum air outlet position.

[0050] S302, the air conditioner corrects the swing upper limit of the air deflector according to the maximum air outlet position and the temperature of the inner coil.

[0051] As described above, the maximum air outlet position of the air conditioner can be determined according to the specific model of the air conditioner. The more times the air deflector passes through the maximum air outlet position during swinging, the more beneficial to the heat dissipation of the inner coil. Therefore, correcting the swing upper limit of the air deflector according to the maximum air outlet position and the temperature of the inner coil can make the correction scheme of the air deflector more beneficial to the heat dissipation of the inner coil, thereby ensuring the normal heating of the air conditioner.

[0052] Optionally, the air conditioner corrects the swing upper limit of the air deflector according to the maximum air outlet position and the temperature of the inner coil, including: the higher the temperature of the inner coil, the smaller the included angle between the swing upper limit of the air deflector controlled by the air conditioner and the maximum air outlet position; or the faster the temperature rise rate of the inner coil, the smaller the included angle between the swing upper limit of the air deflector controlled by the air conditioner and the maximum air outlet position.

[0053] The higher the temperature of the inner coil, the more the heat dissipation of the inner coil needs to be improved. To improve the heat dissipation of the inner coil, it is necessary to control the swing upper limit position of the air deflector to be closer to the maximum air outlet position, that is, to control the included angle between the swing upper limit of the air deflector and the maximum air outlet position to be smaller. Optionally, the temperature of the inner coil and the swing upper limit of the air deflector have a corresponding relationship. For details, see Table 1.

[0054] Temperature T of the inner coil 内 ]]> Upper limit of swing of deflector T 内 <T m ]] Invariable (position A) T m ≤T 内 <T1]]> Position B T1≤T 内 ]]> Position C

[0055] Table 1

[0056] In combination with Figure 4and shown in Table 1, the initial swing upper limit of the deflector is position A, and the initial swing lower limit is position E. The maximum air outlet position is position D. When T 内 <T m , the temperature of the inner coil does not reach the temperature upper limit. At this time, the swing upper limit of the deflector does not need to be corrected, and position A can be maintained. When T m ≤T 内 <T1, the temperature of the inner coil reaches or exceeds the temperature upper limit. At this time, the swing upper limit of the deflector needs to be corrected. The swing upper limit of the deflector is corrected to position B to improve the heat dissipation of the inner coil. When T1≤T 内 , the temperature of the inner coil continues to rise, so the swing upper limit of the deflector needs to be further corrected. At this time, the swing upper limit of the deflector is corrected to position C to further improve the heat dissipation of the inner coil. In this way, by classifying the temperature of the inner coil, different swing upper limits corresponding to different temperature ranges of the inner coil are realized. Only in the case that the temperature of the inner coil further rises, the swing upper limit is corrected to a position closer to the maximum air outlet position. In this way, the difference between the swing upper limit of the deflector and the initial swing upper limit set by the user can be minimized. Optionally, T m is 51℃. T1is 58℃. It should be noted that the specific values of T m and T1may be determined according to actual conditions or air conditioner models, and the present disclosure does not make any limitation thereto. There can be more corresponding relationships between the temperature of the inner coil and the swing upper limit of the deflector.

[0057] After the temperature T 内 of the inner coil reaches the first temperature threshold T m , the faster the temperature rise rate of the inner coil, the more the heat dissipation of the inner coil needs to be improved. To improve the heat dissipation of the inner coil, the swing upper limit position of the deflector needs to be controlled to be closer to the maximum air outlet position, i.e., the included angle between the swing upper limit of the deflector and the maximum air outlet position needs to be made smaller. Optionally, there is a corresponding relationship between the temperature rise rate of the inner coil and the swing upper limit of the deflector. For details, see Table 2.

[0058] Rate of temperature rise V of the inner coil 内 ]] Upper limit of swing of deflector V1≤V 内 V2]]> Position B V2 < V 内 ]]> Position C

[0059] Table 2

[0060] In combination Figure 4 with Table 2, when V1≤V 内 <V2, the temperature rise rate of the inner coil is relatively slow. At this time, the swing upper limit of the deflector is corrected to position B. When V2≤V 内When the temperature rise rate of the inner coil increases, the swing upper limit of the air deflector is corrected to position C. The swing upper limit of the air deflector is closer to the maximum air outlet position, thereby further improving the heat dissipation of the inner coil. In this way, by classifying the temperature rise rate of the inner coil, different swing upper limits corresponding to different temperature rise rate ranges are realized. Only when the temperature rise rate of the inner coil further increases, the swing upper limit is corrected to a position closer to the maximum air outlet position. In this way, the difference between the swing upper limit of the air deflector and the initial swing upper limit set by the user can be minimized. Alternatively, V1 is 0.5°C / min. V2 is 1°C / min. It should be noted that the specific values of V1 and V2 can be determined according to actual conditions, and the present disclosure does not make any limitation thereto. There can be more corresponding relationships between the temperature of the inner coil and the swing upper limit of the air deflector.

[0061] Alternatively, when the swing upper limit of the air deflector is corrected, the corrected swing upper limit is located above the maximum air outlet position. This is because, compared with the swing upper limit being located below the maximum air outlet position, the swing upper limit being located above the maximum air outlet position is closer to the initial swing upper limit set by the user. This also reduces the adjustment relative to the swing range set by the user to a certain extent, so as to avoid affecting the user too much.

[0062] Alternatively, in combination with Figure 5 The embodiment of the present disclosure provides another method for controlling the air deflector of an air conditioner, which comprises the following steps:

[0063] S501, the air conditioner obtains the temperature of the inner coil when the air conditioner is running in a heating mode and the air deflector is freely swinging.

[0064] S502, the air conditioner determines the control demand for the position of the air deflector according to the temperature of the inner coil and the swing range of the air deflector.

[0065] S503, the air conditioner corrects the swing upper limit of the air deflector when the control demand indicates that the position of the air deflector needs to be corrected.

[0066] S504, the air conditioner detects the real-time temperature of the inner coil.

[0067] S505, the air conditioner controls the swing upper limit of the air deflector to return to the initial position when the real-time temperature of the inner coil is less than the second temperature threshold.

[0068] After the swing upper limit of the air deflector is corrected, the air deflector swings in the new swing range. At this time, the heat dissipation of the inner coil is improved. After a period of time, the temperature of the inner coil decreases. The real-time temperature of the inner coil is continuously detected by the temperature sensor. The second temperature threshold T n is set. The real-time temperature of the inner coil is T实 If no user command is received to adjust the oscillation range of the air guide vane, and T... 实 Decrease and T 实 <T n This indicates that the temperature of the inner coil has dropped to a safe range and will not cause the air conditioner to reduce its frequency or stop operating. In this case, the upper limit of the air guide vane's swing is returned to its initial position, that is, back to the initial swing upper limit set by the user. This maximizes the satisfaction of the user's needs. It should be noted that the specific implementation methods of steps S501, S502, and S503 can be found in the above embodiments and will not be repeated here.

[0069] Optionally, T n <T m And T n With T m The difference between them is large. For example, T m If the temperature is 51℃, then T n It is 40℃. This is because, at T 实 <T n After the upper limit of the air guide vane's swing returns to its initial position, the temperature of the inner coil may rise again due to the air guide vane's excessively small airflow angle. If T n With T m If the difference between them is small, the internal coil temperature will rise to T. m The time is relatively short. Then the air conditioner will adjust the upper limit of the air deflector's oscillation again. This leads to the problem of frequently adjusting the upper limit of the air deflector's oscillation, which will inevitably affect the user experience. And if T... n With T m A larger difference between the two values ​​allows sufficient room for the internal coil temperature to rise. This avoids frequent adjustments to the upper limit of the air guide vane's oscillation, ensuring a better user experience. It should be noted that T... n The specific value can be determined according to actual needs, and this disclosure does not impose any restrictions on it.

[0070] Optionally, combined Figure 6 As shown in the embodiments of this disclosure, another method for controlling an air conditioning deflector is provided, including:

[0071] S601, the air conditioner obtains the temperature of the inner coil when it is in heating mode and the air guide plate is swinging freely.

[0072] S602, the air conditioner determines the control requirements for the position of the air guide vane based on the temperature of the inner coil and the swing range of the air guide vane.

[0073] S603, when the control demand indicates that the position of the air guide plate needs to be corrected, the air conditioner corrects the upper limit of the air guide plate's swing.

[0074] S604, in the case that the air conditioner receives an instruction of adjusting the swing upper limit of the air deflector, the air conditioner judges the relative position between the swing upper limit corresponding to the instruction and the current swing upper limit of the air deflector.

[0075] S605, in the case that the angle between the swing upper limit corresponding to the instruction and the maximum air outlet position is smaller than the angle between the current swing upper limit and the maximum air outlet position after the air conditioner executes S604, the swing upper limit of the air deflector is adjusted according to the instruction.

[0076] S606, in the case that the angle between the current swing upper limit and the maximum air outlet position is greater than or equal to the angle between the current swing upper limit and the maximum air outlet position after the air conditioner executes S604, the swing upper limit of the air deflector remains unchanged.

[0077] After the swing upper limit of the air deflector is corrected, the user can still send an instruction of adjusting the swing range to the air conditioner. After the air conditioner receives the instruction, the swing upper limit corresponding to the instruction is compared with the current swing upper limit of the air deflector. If the angle between the swing upper limit corresponding to the instruction and the maximum air outlet position is smaller than the angle between the current swing upper limit and the maximum air outlet position, i.e. the swing upper limit corresponding to the instruction is closer to the maximum air outlet position, the swing upper limit of the air deflector is adjusted according to the instruction. This is because, at this time, adjusting the swing upper limit according to the instruction will be closer to the maximum air outlet position, thus being more conducive to the heat dissipation of the inner coil. If the angle between the current swing upper limit and the maximum air outlet position is greater than the angle between the current swing upper limit and the maximum air outlet position, i.e. the current swing upper limit is closer to the maximum air outlet position, the swing upper limit of the air deflector remains unchanged. This is because, if the swing upper limit is adjusted according to the instruction at this time, the swing upper limit will be far away from the maximum air outlet position. This will result in poor heat dissipation of the inner coil. At this time, the heat dissipation of the inner coil is given priority. Therefore, the swing upper limit of the air deflector remains unchanged to fully ensure the heat dissipation effect of the inner coil. If the angle between the current swing upper limit and the maximum air outlet position is equal to the angle between the current swing upper limit and the maximum air outlet position, i.e. the swing upper limit corresponding to the instruction is the current swing upper limit, the swing upper limit of the air deflector also remains unchanged at this time. It should be noted that the specific implementation of steps S601, S602 and S603 can refer to the above embodiment, which will not be described here.

[0078] Optionally, in combination with Figure 7 as shown, the embodiment of the present disclosure provides another method for controlling the air deflector of an air conditioner, comprising:

[0079] S701, the air conditioner acquires the temperature of the inner coil when it runs in the heating mode and the air deflector swings freely.

[0080] S702, the air conditioner determines the control requirement for the position of the air deflector according to the temperature of the inner coil and the swing range of the air deflector.

[0081] S703, in the case that the control requirement indicates that the position of the air deflector needs to be corrected, the air conditioner corrects the upper limit of the swing of the air deflector.

[0082] S704, in the case that the air conditioner receives an instruction from the user to adjust the upper limit of the swing of the air deflector, the air conditioner judges the relative position between the upper limit of the swing corresponding to the instruction and the current upper limit of the swing of the air deflector.

[0083] S705, after S704, in the case that the included angle between the upper limit of the swing corresponding to the instruction and the maximum air outlet position is smaller than the included angle between the current upper limit of the swing and the maximum air outlet position, the air conditioner controls the upper limit of the swing of the air deflector to be adjusted according to the instruction.

[0084] S706, after S704, in the case that the included angle between the current upper limit of the swing and the maximum air outlet position is greater than or equal to the included angle between the current upper limit of the swing and the maximum air outlet position, the air conditioner controls the upper limit of the swing of the air deflector to remain unchanged.

[0085] S707, after S706, the air conditioner detects the real-time temperature of the inner coil.

[0086] S708, in the case that the real-time temperature of the inner coil is less than the second temperature threshold, the air conditioner controls the upper limit of the swing of the air deflector to be adjusted according to the instruction.

[0087] After the upper limit of the swing of the air deflector is corrected, the air conditioner receives an instruction from the user to adjust the swing range of the air deflector. If the upper limit of the swing corresponding to the instruction is closer to the maximum air outlet position than the current upper limit of the swing, the air conditioner controls the upper limit of the swing of the air deflector to remain unchanged. During the process of the upper limit of the swing remaining unchanged, the air conditioner still detects the real-time temperature of the inner coil through the temperature sensor. If the real-time temperature of the inner coil drops below the second temperature threshold, it indicates that the temperature of the inner coil has dropped to the safe range at this time. At this time, the air conditioner controls the upper limit of the swing of the air deflector to be adjusted according to the instruction, that is, the upper limit of the swing of the air deflector is adjusted to the upper limit of the swing corresponding to the instruction. In this way, the demand of the user for adjusting the upper limit of the swing of the air deflector is met on the premise that the temperature of the inner coil drops to the safe range. It should be noted that the specific implementation of steps S701, S702, S703, S704, S705 and S706 can refer to the above-mentioned embodiments, which will not be described here.

[0088] In practical applications, the temperature of the inner coil is T 内 . The first temperature threshold T m is 51℃. The angle threshold is 5°. In combination with Figure 4As shown, position D is the maximum air outlet position of the air conditioner. Position A is the upper limit of the swing range set by the user, and position E is the lower limit of the swing range set by the user.

[0089] Combination Figure 4 and Figure 8 As shown:

[0090] When T 内 At temperatures below 51℃, the upper limit of the air guide vane's oscillation remains unchanged at position A.

[0091] When 51℃≤T 内 When the angle between position A and position D is less than or equal to 5°, the upper limit of the swing of the air guide plate remains unchanged at position A.

[0092] When 51℃≤T 内 When the temperature is <58℃ and the angle between position A and position D is greater than 5°, the upper limit of the air guide vane's swing should be corrected to position B; for example, when T 内 At 51℃, the upper limit of the swing is corrected to position B, T 内 It can drop to 49°C or below;

[0093] When 58℃≤T 内 When the angle between positions A and D is greater than 5°, the position of the air guide plate is corrected to position C; for example, when T 内 At 58℃, the upper limit of the swing is corrected to position C, T 内 It can drop to 56°C or below.

[0094] Combination Figure 9 As shown, this disclosure provides an apparatus for controlling an air conditioner air guide vane, including: an acquisition module 91, a determination module 92, and a correction module 93. The acquisition module 91 is configured to acquire the temperature of the inner coil when the air conditioner is operating in heating mode and the air guide vane is freely swinging. The determination module 92 is configured to determine a control requirement for the position of the air guide vane based on the temperature of the inner coil and the swing range of the air guide vane. The correction module 93 is configured to correct the upper limit of the swing of the air guide vane when the control requirement indicates that the position of the air guide vane needs to be corrected.

[0095] The device for controlling the air deflector of the air conditioner provided by the embodiment of the present disclosure judges whether the air deflector has the demand for position correction based on the current swing range of the air deflector and the real-time temperature of the inner coil. If yes, the swing upper limit of the air deflector is corrected. The swing range after the correction is more conducive to the heat dissipation of the inner coil. In this way, the possibility of the air conditioner entering the frequency reduction or shutdown protection due to the excessively high temperature of the inner coil is reduced, thereby ensuring the heating effect of the air conditioner. Moreover, the heat dissipation of the inner coil is improved by correcting the swing upper limit of the air deflector, and the rotation speed of the fan does not need to be increased. In this way, the generation of large wind noise is avoided, and the user experience is improved. After the swing upper limit of the air deflector is corrected, the air deflector freely swings in the new swing range. In this way, the will of the user for freely swinging the air deflector is not violated, and the demand of the user is fully met.
