Background

Air conditioning is a common device in home life, and can adjust indoor temperature by heating or cooling indoor air. When the user can set the air conditioner to swing and send air, the air deflector swings freely in the maximum range. When the air conditioner operates in a heating mode, the temperature of the inner coil pipe gradually rises along with the rise of the indoor temperature. If the air deflector is free to swing within the maximum range, the assistance to the temperature rise of the coil is provided. At this time, the air conditioner can automatically reduce the frequency of the compressor, the rotating speed of the outer fan and the like, and the temperature of the inner coil pipe cannot rise too fast. This will lower the temperature of the inner coil but at the same time will lower the temperature of the air conditioner outlet.

The prior method and device for controlling air conditioner heat and air conditioner, wherein the method comprises the following steps: acquiring the current position of a guide plate of a heating mode operation air conditioner, wherein the guide plate is in a free air swinging mode operation; determining the current rotating speed of an indoor fan of the air conditioner corresponding to the current position according to the fact that the air outlet volume of the air conditioner corresponding to each position of the guide plate is the same; and controlling the heating operation of the air conditioner according to the current rotating speed.

According to the control method, the maintenance of the air quantity is ensured through the adjustment of the rotating speed of the inner fan, so that the temperature of the inner coil is not easy to touch a protection line. However, when the guide plate is at the position with larger wind resistance, larger wind noise can appear when the inner rotation speed of the fan is improved, so that the user experience is influenced.

Referring to fig. 1, an embodiment of the present disclosure provides a method for controlling an air deflector of an air conditioner, including:

s101, the air conditioner obtains the temperature of the inner coil under the condition that the air conditioner runs in a heating mode and the air deflector swings freely.

S102, the air conditioner determines the control requirement on the position of the air deflector according to the temperature of the inner coil pipe and the swing range of the air deflector.

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

The user sends a heating instruction and a free swinging instruction of the air deflector to the air conditioner through the air conditioner remote controller or the terminal equipment. The air conditioner receives and responds to the instruction sent by the user. The air conditioner operates in a heating mode, and the air deflector swings freely according to a swing range set by a user. 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 pipe through the temperature sensor. The air deflector is connected with an angle sensor. The air conditioner can acquire the opening angle of the air deflector through the angle sensor, so that the swing upper limit of the air deflector can be determined. And determining the control requirement on the position of the air deflector according to the detected swing range of the air deflector and the temperature of the inner coil, namely judging whether the position of the air deflector needs to be corrected or not. When the control requirement indicates that the position of the air deflector does not need to be corrected, the swing range of the air deflector is kept unchanged. When the control requirement indicates that the position of the air deflector needs to be corrected, the upper swing limit of the air deflector is corrected, and the lower swing limit of the air deflector is kept unchanged. The post-correction wobble range is a region between the post-correction wobble upper limit and the initial wobble lower limit. The air deflector swings freely in the swing range after correction.

In the embodiment of the disclosure, whether the air deflector has a position correction requirement is judged based on the current swing range of the air deflector and the real-time temperature of the inner coil. If so, the upper limit of swing of the air deflector is corrected. The corrected swing range is more beneficial to the heat dissipation of the inner coil pipe. Therefore, the possibility that the air conditioner enters down-conversion or shutdown protection due to the fact that the temperature of the inner coil pipe is too high is reduced, and therefore the heating effect of the air conditioner is guaranteed. In addition, the upper swing limit of the air deflector is corrected to improve the heat dissipation of the inner coil pipe, so that the rotating speed of the fan does not need to be improved. Thus, the generation of larger wind noise is avoided, and the user experience is improved. After the upper limit of the swing of the air deflector is corrected, the air deflector swings freely in a new swing range. Therefore, the free swing wish of the air deflector set by a user is not violated, and the requirements of the user are fully met.

As shown in conjunction with fig. 2, an embodiment of the present disclosure provides another method for controlling an air deflector of an air conditioner, including:

s201, the air conditioner obtains the temperature of the inner coil pipe under the condition that the air conditioner runs in a heating mode and the air deflector swings freely.

S202, the air conditioner determines the maximum air outlet position.

S203, under the condition that the temperature of the inner coil pipe is larger than a first temperature threshold value and the included angle between the swing upper limit of the air deflector and the maximum air outlet position is larger than an angle threshold value, the air conditioner determines that the control requirement is that the position of the air deflector needs to be corrected.

S204, when the temperature of the inner coil is smaller than or equal to a first temperature threshold value, or when the temperature of the inner coil is larger than the first temperature threshold value and the included angle between the swing upper limit of the air deflector and the maximum air outlet position is smaller than or equal to an angle threshold value, the air conditioner determines that the control requirement is that the position of the air deflector does not need to be corrected.

S205, after the air conditioner executes S203, if the control requirement indicates that the position of the air deflector needs to be corrected, the air conditioner corrects the swing upper limit of the air deflector.

S206, after the air conditioner executes S204, if the control requirement indicates that the position of the air deflector is not required to be corrected, the swing range of the air conditioner control air deflector is unchanged.

The user sends a heating instruction and a free swinging instruction of the air deflector to the air conditioner through the air conditioner remote controller or the terminal equipment. The air conditioner receives and responds to the instruction sent by the user. The air conditioner operates in a heating mode, and the air deflector swings freely according to a swing range set by a user. 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 pipe through the temperature sensor. The air deflector is connected with an angle sensor. The air conditioner can acquire the opening angle of the air deflector through the angle sensor, so that the swing upper limit of the air deflector can be determined.

When the air conditioner leaves the factory, the maximum air outlet position of the air conditioner is preset. Different models have different maximum air outlet positions. Therefore, the maximum air outlet position matched with the air conditioner model can be obtained in the manufacturer database. The closer the position of the air deflector is to the maximum air outlet position, the smaller the impedance of the air deflector to the air outlet is, and the larger the heat dissipation capacity of the inner coil pipe is. When the air deflector is at the maximum air outlet position, the impedance of the air deflector to the air outlet is minimum, and the heat dissipation capacity of the inner coil pipe is maximum. And in the same time period, the larger the included angle between the swing upper limit of the air deflector and the maximum air outlet position is, the longer the air deflector swings from the swing upper limit to the maximum air outlet position, the fewer the times that the air deflector passes through the maximum air outlet position is, and the heat dissipation of the inner coil is not facilitated. And setting an angle threshold value, and when the included angle between the swing upper limit of the air deflector and the maximum air outlet position is smaller than or equal to the angle threshold value, considering that the heat dissipation effect of the inner coil is optimal. Optionally, the angle threshold is 0 ° to 5 °. It should be noted that the angle threshold may be determined according to actual needs, and the present embodiment does not limit the angle threshold.

The temperature of the inner coil pipe is T _{Inner part} . Setting a first temperature threshold T _m 。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 _{Inner part} ≤T _m And the included angle between the swing upper limit of the air deflector and the maximum air outlet position is larger than an angle threshold value. At this time, the temperature of the inner coil pipe exceeds the upper limit, and the swing upper limit of the air deflector is far away from the maximum air outlet position, which is not beneficial to heat dissipation of the inner coil pipe. In this case, the control requirement is determined to require a correction to the position of the deflector to increase the heat dissipation of the inner coil. And then controlling the air deflector to swing freely between the upper swing limit after correction and the lower swing limit. If T _{Inner part} ≤T _m This means that the temperature of the inner coil does not reach the upper limit, and therefore, the position of the air deflector does not need to be corrected. In this case, the control requirement is determined such that no correction of the position of the deflector is required. If T _{Inner part} ＞T _m And the air deflector swingsThe included angle between the upper limit and the maximum air outlet position is smaller than or equal to an angle threshold value. At this time, the temperature of the inner coil pipe exceeds the upper limit, but the air deflector is closer to the maximum air outlet position, and the air deflector position of the air deflector can enable the heat dissipation of the inner coil pipe to reach the optimal state. In this case, the position of the air deflector does not need to be corrected. Thus, the control requirement is determined such that no correction to the position of the deflector is required. When the position of the air deflector is not required to be corrected, the current upper limit of swing of the air deflector is kept unchanged. Therefore, whether the position of the air deflector is required to be corrected is judged in real time based on the temperature of the inner coil pipe and the position of the air deflector, the judgment result can be more accurate, and the air deflector position can be controlled more accurately.

Referring to fig. 3, the air conditioner corrects the upper limit of swing of the air deflector, including:

s301, the air conditioner determines the maximum air outlet position.

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.

As described above, the maximum outlet position of the air conditioner may be determined according to a specific model of the air conditioner. The more times the air deflector passes through the maximum air outlet position in the swinging process, the more beneficial the heat dissipation of the inner coil is. Therefore, the upper limit of swing of the air deflector is corrected according to the maximum air outlet position and the temperature of the inner coil, so that the correction scheme of the air deflector is more beneficial to heat dissipation of the inner coil, and the normal heating of the air conditioner is ensured.

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 pipe is, the smaller the included angle between the swing upper limit of the air conditioner control air deflector and the maximum air outlet position is; or the faster the temperature rising speed of the inner coil pipe is, the smaller the included angle between the swing upper limit of the air conditioner control air deflector and the maximum air outlet position is.

The higher the temperature of the inner coil, the more heat is dissipated from the inner coil. To improve the heat dissipation to the inner coil, the swing upper limit position of the air deflector needs to be controlled to be closer to the maximum air outlet position, namely the included angle between the swing upper limit of the air deflector and the maximum air outlet position needs to be controlled to be smaller. Optionally, there is a correspondence between the temperature of the inner coil and the upper limit of oscillation of the deflector. See in particular table 1.

Temperature T of the inner coil _{Inner part}	Upper limit of swing of air deflector
		T _{Inner part} ＜T _m	Unchanged (position A)
T _m ≤T _{Inner part} ＜T ₁	Position B
		T ₁ ≤T _{Inner part}	Position C

TABLE 1

As shown in fig. 4 and table 1, the upper limit of initial swing of the wind deflector is position a, and the lower limit of initial swing is position E. The maximum air outlet position is position D. When T is _{Inner part} ＜T _m When the temperature of the inner coil does not reach the upper temperature limit. At this time, the upper limit of the swing of the air deflector is not required to be corrected, and the air deflector can be kept at the position A. When T is _m ≤T _{Inner part} ＜T ₁ When the temperature of the inner coil reaches or even exceeds the upper temperature limit. In this case, the upper limit of the swing of the deflector needs to be corrected. And correcting the swing upper limit of the air deflector to the position B so as to improve the heat dissipation of the inner coil. When T is ₁ ≤T _{Inner part} The temperature of the inner coil pipe is continuously increased, so that the upper limit of swing of the air deflector is required to be further increasedAnd (5) correcting. At this time, the upper limit of the swing of the air deflector is corrected to the position C to further improve the heat dissipation of the inner coil. Thus, by grading the temperature of the inner coil, different upper swing limits corresponding to different inner coil temperature ranges are realized. Only if the inner coil temperature further increases, the upper swing limit is corrected to a position closer to the maximum air outlet position. In this way, the difference between the upper swing limit of the air guide plate and the initial upper swing limit set by the user can be reduced to the maximum. Alternatively T _m 51 ℃. T (T) ₁ 58 ℃. T is the same as _m And T ₁ The specific value of (c) may be determined according to the actual situation or the model of the air conditioner, and the present disclosure does not limit the specific value. There may also be more correspondence between the temperature of the inner coil and the upper swing limit of the deflector.

Temperature T of the inner coil _{Inner part} Reaching a 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 increased. The heat dissipation of the inner coil pipe is improved, the swing upper limit position of the air deflector needs to be controlled to be closer to the maximum air outlet position, namely the included angle between the swing upper limit position and the maximum air outlet position of the air deflector needs to be controlled to be reduced. Optionally, there is a correspondence between the rate of rise of the temperature of the inner coil and the upper limit of oscillation of the deflector. See in particular table 2.

Rate of rise of temperature V of inner coil _{Inner part}	Upper limit of swing of air deflector
		V ₁ ≤V _{Inner part} ＜V ₂	Position B
V ₂ ≤V _{Inner part}	Position C

TABLE 2

As shown in combination with FIG. 4 and Table 2, when V ₁ ≤V _{Inner part} ＜V ₂ The temperature rise rate of the inner coil is slower. At this time, the upper limit of the swing of the deflector is corrected to the position B. When V is ₂ ≤V _{Inner part} As the temperature rise rate of the inner coil increases. At this time, the upper limit of the swing of the deflector is corrected to the position C. The swing upper limit of the air deflector is closer to the maximum air outlet position, so that the heat dissipation of the inner coil is further improved. Thus, by grading the rate of rise of the temperature of the inner coil, different upper swing limits for different rise rate ranges are achieved. Only if the rate of rise of the inner coil temperature increases further, the upper swing limit is corrected to a position closer to the maximum air outlet position. In this way, the difference between the upper swing limit of the air guide plate and the initial upper swing limit set by the user can be reduced to the maximum. Alternatively V ₁ Is 0.5 ℃/min. V (V) ₂ Is 1 ℃/min. V is also described as ₁ And V ₂ The specific value of (c) may be determined according to the actual situation, and the disclosure does not limit the specific value. There may also be more correspondence between the temperature of the inner coil and the upper swing limit of the deflector.

Optionally, when the upper limit of the swing of the air deflector is corrected, the corrected upper limit of the swing is limited at and above the maximum air outlet position. This is because the upper swing limit is closer to the initial upper swing limit set by the user when the upper swing limit is above the maximum air outlet position than when the upper swing limit is below the maximum air outlet position. This also reduces the adjustment of the swing range with respect to the user setting to some extent. To avoid having a large impact on the user.

Optionally, as shown in conjunction with fig. 5, another method for controlling an air deflector of an air conditioner is provided according to an embodiment of the present disclosure, including:

s501, the air conditioner obtains the temperature of the inner coil under the condition that the air conditioner runs in a heating mode and the air deflector swings freely.

S502, the air conditioner determines the control requirement on the position of the air deflector according to the temperature of the inner coil pipe and the swing range of the air deflector.

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

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

And S505, returning the swing upper limit of the air conditioner control air deflector to the initial position under the condition that the real-time temperature of the inner coil pipe is smaller than the second temperature threshold value.

After correcting the swing upper limit of the air deflector, the air deflector swings in a new swing range to guide air. At this time, the heat dissipation capacity of the inner coil is improved. After a period of time, the temperature of the inner coil will drop. The real-time temperature of the inner coil is continuously detected by the temperature sensor. Setting a second temperature threshold T _n . The real-time temperature of the inner coil pipe is T _{Real world} . If the instruction of adjusting the swing range of the air deflector sent by the user is not received, T _{Real world} Descending and T _{Real world} ＜T _n The temperature of the inner coil pipe is reduced to a safe range, and the problem of air conditioner frequency reduction or shutdown is avoided. In this case, the upper swing limit of the air guide plate is controlled to return to the initial position, that is, to the initial upper swing limit set by the user. In this way, the user's needs can be satisfied to the maximum extent. It should be noted that, for the specific implementation manners of steps S501, S502 and S503, refer to the above embodiments, and are not described herein again.

Alternatively T _n ＜T _m And T is _n And T is _m The difference between them is large. For example T _m At 51 ℃, T _n Is 40 ℃. This is because, at T _{Real world} ＜T _n After the swing upper limit of the air guide plate is controlled to return to the initial position, the temperature of the inner coil pipe can be increased again due to the fact that the air guide angle of the air guide plate is too small. If T _n And T is _m The difference between the two is smaller, the temperature of the inner coil pipe is increased to T _m The time of (2) is shorter. The air conditioner corrects the upper limit of swing of the air deflector. This is thenThe problem of frequently adjusting the swing upper limit of the air deflector is caused, and the experience of a user is influenced. And if T _n And T is _m The difference between the two is larger, so that enough rising space can be reserved for the temperature of the inner coil. Therefore, the upper limit of swing of the air deflector is prevented from being frequently adjusted, and the experience of a user is ensured. T is the same as _n The specific values of (c) may be determined according to actual needs, and are not limited in any way by the present disclosure.

Optionally, as shown in connection with fig. 6, another method for controlling an air deflector of an air conditioner is provided according to an embodiment of the present disclosure, including:

s601, the air conditioner obtains the temperature of the inner coil under the condition that the air conditioner runs in a heating mode and the air deflector swings freely.

S602, the air conditioner determines the control requirement on the position of the air deflector according to the temperature of the inner coil pipe and the swing range of the air deflector.

S603, when the control requirement indicates that the position of the air deflector needs to be corrected, the air conditioner corrects the swing upper limit of the air deflector.

S604, when the air conditioner receives an instruction of adjusting the swing upper limit of the air deflector by a user, 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.

S605, after the air conditioner executes S604, under the condition that the included angle between the swing upper limit corresponding to the instruction and the maximum air outlet position is smaller than the included angle between the current swing upper limit and the maximum air outlet position, the swing upper limit of the air deflector is controlled to be adjusted according to the instruction.

S606, after the air conditioner executes S604, under the condition that the included angle between the current swing upper limit and the maximum air outlet position is larger than or equal to the included angle between the current swing upper limit and the maximum air outlet position, the swing upper limit of the air deflector is controlled to be unchanged.

After correcting the upper limit of the swing of the air deflector, the user may also send an instruction to adjust 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 included angle between the swing upper limit corresponding to the instruction and the maximum air outlet position is smaller than the included angle between the current swing upper limit and the maximum air outlet position, namely, 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 controlled to be adjusted according to the instruction. This is because the upper swing limit is adjusted according to the instruction at this time, the maximum air outlet position is closer, and heat dissipation of the inner coil is more facilitated. If the included angle between the current swing upper limit and the maximum air outlet position is larger than the included angle between the current swing upper limit and the maximum air outlet position, namely, the current swing upper limit is closer to the maximum air outlet position, the swing upper limit of the air deflector is controlled to be unchanged. This is because if the upper swing limit is adjusted as instructed at this time, the upper swing limit is away from the maximum air outlet position. This results in poor heat dissipation from the inner coil. At this time, the heat dissipation of the inner coil is mainly ensured. Therefore, the upper limit of swing of the air deflector is controlled to be unchanged, so that the heat dissipation effect on the inner coil is fully ensured. If the included angle between the current swing upper limit and the maximum air outlet position is equal to the included angle between the current swing upper limit and the maximum air outlet position, namely the swing upper limit corresponding to the instruction is the current swing upper limit, and the swing upper limit of the air deflector is controlled to be unchanged at the moment. It should be noted that, for the specific implementation manners of steps S601, S602, and S603, refer to the above embodiments, and are not described herein again.

Optionally, as shown in connection with fig. 7, another method for controlling an air deflector of an air conditioner is provided according to an embodiment of the present disclosure, including:

s701, the air conditioner obtains the temperature of the inner coil under the condition that the air conditioner runs in a heating mode and the air deflector swings freely.

S702, the air conditioner determines the control requirement on the position of the air deflector according to the temperature of the inner coil pipe and the swing range of the air deflector.

S703, when the control requirement indicates that the position of the air guide plate needs to be corrected, the air conditioner corrects the swing upper limit of the air guide plate.

S704, when the air conditioner receives the instruction of adjusting the swing upper limit of the air deflector by the user, 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.

And S705, after the air conditioner executes S704, controlling the swing upper limit of the air deflector to be adjusted according to the instruction under the condition that the included angle between the swing upper limit corresponding to the instruction and the maximum air outlet position is smaller than the included angle between the current swing upper limit and the maximum air outlet position.

S706, after the air conditioner executes S704, under the condition that the included angle between the current swing upper limit and the maximum air outlet position is larger than or equal to the included angle between the current swing upper limit and the maximum air outlet position, the swing upper limit of the air deflector is controlled to be unchanged.

S707, after the air conditioner performs S706, detecting the real-time temperature of the inner coil.

And S708, adjusting the swing upper limit of the air conditioner control air deflector according to the instruction under the condition that the real-time temperature of the inner coil is smaller than the second temperature threshold value.

After correcting the swing upper limit of the air deflector, the air conditioner receives a command of a user for adjusting the swing range of the air deflector. And if the swing upper limit corresponding to the instruction is closer to the maximum air outlet position than the current swing upper limit, controlling the swing upper limit of the air deflector to be unchanged. During the process that the swing upper limit is kept 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 falls below the second temperature threshold, this indicates that the temperature of the inner coil has fallen within the safe range. At the moment, the upper limit of the swing of the air deflector is controlled to be adjusted according to the instruction, namely, the upper limit of the swing of the air deflector is adjusted to the upper limit of the swing corresponding to the instruction. Therefore, on the premise that the temperature of the inner coil pipe is reduced to a safe range, the requirement of a user on adjusting the swing upper limit of the air deflector is met. It should be noted that, for the specific implementation manners of steps S701, S702, S703, S704, S705 and S706, reference is made to the above embodiments, and the details are not repeated here.

In practical application, the temperature of the inner coil pipe is T _{Inner part} . First temperature threshold T _m 51 ℃. The angle threshold is 5 °. As shown in fig. 4, the 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 upper limit for settingThe lower swing limit of the swing range.

As shown in connection with fig. 4 and 8:

when T is _{Inner part} When the temperature is less than 51 ℃, the swing upper limit of the air deflector is kept unchanged at the position A;

when the temperature is not more than 51 ℃ and is not more than T _{Inner part} When the included angle between the position A and the position D is smaller than or equal to 5 degrees, the swing upper limit of the air deflector is kept unchanged at the position A;

when the temperature is not more than 51 ℃ and is not more than T _{Inner part} When the temperature is less than 58 ℃ and the included angle between the position A and the position D is more than 5 ℃, correcting the swing upper limit of the air deflector to the position B; for example, when T _{Inner part} when=51deg.C, the upper swing limit is corrected to position B, T _{Inner part} Can be lowered to 49 ℃ or below;

when the temperature is less than or equal to 58 ℃ T _{Inner part} When the included angle between the position A and the position D is larger than 5 degrees, correcting the position of the air deflector to the position C; for example, when T _{Inner part} When 58 ℃, the upper swing limit is corrected to the position C, T _{Inner part} Can be lowered to 56 ℃ and below.

Referring to fig. 9, an embodiment of the present disclosure provides an apparatus for controlling an air deflector of an air conditioner, 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 in the case where the air conditioner is operating in the heating mode and the air deflector is free to swing. The determination module 92 is configured to determine a control demand for the position of the air deflection based on the temperature of the inner coil and the range of oscillation of the air deflection. The correction module 93 is configured to correct the upper limit of oscillation of the air deflector if the control demand indicates that correction of the position of the air deflector is required.

By adopting the device for controlling the air conditioner air deflector provided by the embodiment of the disclosure, whether the air deflector has the position correction requirement is judged based on the current swing range of the air deflector and the real-time temperature of the inner coil. If so, the upper limit of swing of the air deflector is corrected. The corrected swing range is more beneficial to the heat dissipation of the inner coil pipe. Therefore, the possibility that the air conditioner enters down-conversion or shutdown protection due to the fact that the temperature of the inner coil pipe is too high is reduced, and therefore the heating effect of the air conditioner is guaranteed. In addition, the upper swing limit of the air deflector is corrected to improve the heat dissipation of the inner coil pipe, so that the rotating speed of the fan does not need to be improved. Thus, the generation of larger wind noise is avoided, and the user experience is improved. After the upper limit of the swing of the air deflector is corrected, the air deflector swings freely in a new swing range. Therefore, the free swing wish of the air deflector set by a user is not violated, and the requirements of the user are fully met.
