Referring to Fig. 1, the air conditioner includes an indoor unit 10, a guide plate 20, an indoor fan 30, an indoor heat exchanger 40, and a compressor. The indoor unit 10 has an air outlet, and the guide plate 20 is arranged at the air outlet. The size of the air volume indicated by adjusting the rotation speed of the indoor fan 30, thereby adjusting the wind speed. The air volume change command can be sent by the remote controller. The indoor fan 30 , the indoor heat exchanger 40 and the compressor are all arranged in the indoor unit 10 .

As shown in FIG. 2 , an embodiment of the present disclosure provides a method for controlling an air conditioner, including:

S01, when the air conditioner receives an air volume conversion instruction, it controls the guide plate to close for a preset duration, and controls the speed of the indoor fan to increase.

S02, the control guide plate of the air conditioner is opened to the initial position, and the indoor fan is controlled to run according to the preset mode.

The air volume change command can be sent by the remote controller. The air conditioner controls the guide plate to close for a preset period of time when receiving the air volume conversion instruction. Optionally, the preset duration is 10s. Generally speaking, the blowing of water droplets will almost only happen within 1s-2s of the air volume change. The reason for closing the guide plate for 10s is to blow out the water as much as possible to avoid blowing water after the guide plate is opened. When the guide plate is closed, the air conditioner controls the speed of the indoor fan to increase rapidly. For example, the speed of the increase of the rotational speed of the indoor fan is 100 n/s, so as to blow the water drops onto the guide plate. After the guide plate is closed for a preset period of time, the air conditioner controls the guide plate to open to an initial position, and the initial position is the position of the guide plate before receiving the air volume conversion instruction. At the same time, the indoor fan is controlled to run according to the preset mode, so as to adjust the air volume according to the air volume conversion instruction.

In the embodiment of the present disclosure, when the air volume of the air conditioner changes, the control guide plate is closed first, and the speed of the indoor fan is controlled to increase. If there is water blowing, due to the increase in the speed of the indoor fan, the water will be blown out, and the closed guide plate can intercept the blown water, thereby reducing the phenomenon of blowing water from the air conditioner and improving the user experience. The guide plate is closed for a preset period of time and then opened, and the indoor fan is controlled to run according to the preset mode, which can ensure that the air conditioner runs normally according to the air volume conversion instruction after intercepting the blowing water, and the normal air output does not affect the normal use of the user.

Optionally, as shown in Fig. 3, the fan in the control room operates according to a preset mode, including:

S31, the air conditioner controls the rotation speed of the indoor fan to decrease to the rotation speed before the air volume conversion at a first preset speed.

S32, the air conditioner controls the speed of the indoor fan to increase to a set wind speed at a second preset speed.

The air conditioner controls the rotational speed of the indoor fan to decrease at a first preset speed until the rotational speed of the indoor fan returns to the rotational speed before receiving the air volume conversion instruction. Then, the air conditioner controls the speed of the indoor fan to increase at a second preset speed until it reaches a set speed, and the wind speed corresponding to the set speed is the wind speed indicated by the air volume conversion command.

In the embodiment of the present disclosure, the rotational speed of the indoor unit is controlled to drop to the initial rotational speed first, and then increase to the set rotational speed, which can avoid the problem that the water droplets on the guide plate are easily blown off when directly descending or rising to the set rotational speed.

Optionally, the first preset speed is greater than the second preset speed, that is, the air conditioner controls the speed of the indoor fan to drop rapidly at the first preset speed, and then slowly increase at the second preset speed. Optionally, the first preset speed is 100n/s, and the second preset speed is 10n/s. When blowing water occurs, the water droplets blown out are generally small and scattered, so the water droplets blown out will be scattered on the guide plate, so the speed of the indoor fan is controlled to increase slowly to prevent the water droplets on the guide plate from being blown off.

Optionally, as shown in Fig. 4, the fan in the control room operates according to a preset mode, including:

S41, the air conditioner controls the rotation speed of the indoor fan to decrease to the rotation speed before the air volume conversion at a first preset speed.

S42, the air conditioner controls the rotation speed of the indoor fan to increase to the set wind speed at a second preset speed, and controls the position of the guide plate to remain unchanged.

The air conditioner controls the rotational speed of the indoor fan to decrease at a first preset speed until the rotational speed of the indoor fan returns to the rotational speed before receiving the air volume conversion instruction. Then, the air conditioner controls the speed of the indoor fan to increase at a second preset speed until it reaches a set speed, and the wind speed corresponding to the set speed is the wind speed indicated by the air volume conversion command. During the increase of the speed of the indoor fan, the position of the control guide plate remains unchanged, that is, during the increase of the speed of the indoor fan, the position of the guide plate is always at the position of the guide plate before the air conditioner receives the air volume change command.

In the embodiment of the present disclosure, during the process of increasing the speed of the indoor fan, the position of the guide plate remains unchanged, so as to avoid the simultaneous change of the wind speed and the guide plate, so as to reduce the probability of water droplets being blown off.

Optionally, as shown in Fig. 5, the fan in the control room operates according to a preset mode, including:

S51. The air conditioner controls the rotation speed of the indoor fan to decrease to the rotation speed before the air volume conversion at a first preset speed, and controls the compressor frequency to decrease to the compressor operating frequency before the air volume conversion at the first preset frequency reduction speed.

S52, the air conditioner controls the speed of the indoor fan to increase to a set wind speed at a second preset speed.

The air conditioner controls the rotational speed of the indoor fan to decrease at a first preset speed until the rotational speed of the indoor fan returns to the rotational speed before receiving the air volume conversion instruction. At the same time, the frequency of the compressor is controlled to decrease at a first preset frequency reduction rate until the frequency of the compressor returns to the operating frequency before the air volume change. Optionally, the first preset frequency reduction speed is 10 Hz/s. Then, the air conditioner controls the speed of the indoor fan to increase at a second preset speed until it reaches a set speed, and the wind speed corresponding to the set speed is the wind speed indicated by the air volume conversion command.

In the embodiment of the present disclosure, when the rotation speed of the indoor fan decreases, the frequency of the compressor is controlled to decrease, so as to ensure the normal operation of the air conditioner.

Optionally, as shown in Fig. 6, the fan in the control room operates according to a preset mode, including:

S61. The air conditioner controls the speed of the indoor fan to decrease to the speed before the air volume conversion at a first preset speed, and controls the frequency of the compressor to decrease the operating frequency of the compressor before the air volume conversion at the first preset frequency reduction speed.

S62, the air conditioner controls the rotation speed of the indoor fan to increase to the set wind speed at a second preset speed, and controls the position of the guide plate to remain unchanged.

The air conditioner controls the rotational speed of the indoor fan to decrease at a first preset speed until the rotational speed of the indoor fan returns to the rotational speed before receiving the air volume conversion instruction. At the same time, the frequency of the compressor is controlled to decrease at a first preset frequency reduction rate until the frequency of the compressor returns to the frequency before the air volume change. Optionally, the first preset frequency reduction speed is 10 Hz/s. Then, the air conditioner controls the speed of the indoor fan to increase at a second preset speed until it reaches a set speed, and the wind speed corresponding to the set speed is the wind speed indicated by the air volume conversion instruction. During the process of increasing the speed of the indoor fan, the position of the control guide plate remains unchanged, that is, the position of the guide plate is always at the position of the guide plate before the air conditioner receives the air volume conversion instruction.

In the embodiment of the present disclosure, when the rotation speed of the indoor fan decreases, the frequency of the compressor is controlled to decrease, so as to ensure the normal operation of the air conditioner. At the same time, when the speed of the indoor fan is rising, the position of the guide plate remains unchanged to avoid simultaneous changes in the wind speed and the guide plate, so as to reduce the probability of water droplets being blown off.

Optionally, as shown in FIG. 7 , an embodiment of the present disclosure provides another method for controlling an air conditioner, including:

S01, when the air conditioner receives the air volume conversion instruction, control the guide plate to close for a preset duration, control the speed of the indoor fan to increase, and control the frequency of the compressor to drop to the preset frequency at the second preset frequency reduction speed; where , the preset frequency is lower than the operating frequency of the compressor before the air volume change.

The air volume change command can be sent by the remote controller. The air conditioner controls the guide plate to close for a preset period of time when receiving the air volume conversion command. Optionally, the preset duration is 10s. Generally speaking, the blowing out of water droplets will almost only happen within 1s-2s of the air volume change, and the guide plate is closed for 10s to blow out the water as much as possible, so as to avoid the phenomenon of blowing water after the guide plate is opened. When the guide plate is closed, the air conditioner controls the speed of the indoor fan to increase rapidly. For example, the speed of the increase of the rotational speed of the indoor fan is 100 n/s, so as to blow the water drops onto the guide plate. The frequency of the compressor is controlled to drop to a preset frequency at a second preset frequency reduction speed, wherein the preset frequency is lower than the running frequency of the compressor before the air volume is changed. Optionally, the second preset frequency reduction speed is 10 Hz/s, and the preset frequency is 0.5 times the operating frequency of the compressor before the air volume change. After the guide plate is closed for a preset period of time, the air conditioner controls the guide plate to open to an initial position, and the initial position is the position of the guide plate before receiving the air volume conversion instruction. At the same time, the indoor fan is controlled to run according to the preset mode, so as to adjust the air volume according to the air volume conversion instruction.

In the embodiment of the present disclosure, when the air volume of the air conditioner changes, the control guide plate is closed first, and the speed of the indoor fan is controlled to increase. If there is water blowing, due to the increase in the speed of the indoor fan, the water will be blown out, and the closed guide plate can intercept the blown water, thereby reducing the phenomenon of blowing water from the air conditioner and improving the user experience. During the closure of the guide plate, the frequency of the compressor drops below the original operating frequency to avoid high frequency operation of the compressor when the guide plate is closed, which will cause the compressor to stop due to high system pressure. The guide plate is closed for a preset period of time and then opened, and the indoor fan is controlled to run according to the preset mode, which can ensure that the air conditioner runs normally according to the air volume conversion instruction after intercepting the blowing water, and the normal air output does not affect the normal use of the user.

Optionally, as shown in FIG. 8 , an embodiment of the present disclosure provides another method for controlling an air conditioner, including:

S03, the air conditioner detects the water blowing situation in real time.

S04. In the case of no water blowing out, the air conditioner determines that the guide plate needs to be opened.

S05, when there is water blowing out, the air conditioner control guide plate continues to be in the closed state, and continues to detect the water blowing situation, until no water blows out, then the air conditioner determines that the guide plate needs to be opened.

A sensor is arranged in the indoor unit or on the guide plate to detect whether water is blown out. During the closing of the guide plate, the air conditioner can detect the water blowing situation through the sensor. In the case of no water blowing out, that is, the sensor does not detect that there is water blowing out, the air conditioner determines that the guide plate needs to be opened, and then the air conditioner controls the guide plate to open to the initial position. In the case of water blowing out, that is, when the sensor detects that water is blowing out, the air conditioner determines that the guide plate continues to be in a closed state, and continues to detect the water blowing situation through the sensor. Until no water blowing out is detected, the air conditioner determines that the guide plate needs to be opened, and then the air conditioner controls the guide plate to open to the initial position.

It should be noted that, the specific implementation process of S01 and S02 can refer to the above-mentioned embodiment, and will not be repeated here.

In the embodiment of the present disclosure, during the closing of the guide plate, the water blowing condition is detected in real time, and it is determined whether the guide plate needs to be opened according to the detected water blowing condition. Until it is determined that the guide plate needs to be opened, then control the guide plate to open to the initial position, so as to fully ensure that the guide plate intercepts the blown water droplets, and avoid water still blowing into the room after the guide plate is opened.

Optionally, as shown in FIG. 9 , an embodiment of the present disclosure provides another method for controlling an air conditioner, including:

S03, the air conditioner detects the water blowing situation in real time.

It should be noted that the specific implementation process of S01, S02, S03, S04 and S05 can be referred to the above-mentioned embodiment, and will not be repeated here.

The following will illustrate the specific implementation process of a method for controlling an air conditioner provided in this embodiment with an example:

In the cooling mode, when the air conditioner receives an instruction from the remote controller to change the air volume from a lower air volume to a higher air volume, the air conditioner control guide plate is first closed. At the same time, the compressor runs at a frequency 0.5 times the original operating frequency at a frequency reduction speed of 10Hz/s. At this time, the speed of the indoor fan increases rapidly, and the air volume changes. If there is water blowing, the water will be blown onto the guide plate instead of blowing out directly. The guide plate is closed for 10s, and then returns to the position before receiving the instruction. At the same time, the speed of the indoor fan drops rapidly at a speed of 100n/s to the speed before the wind speed change, and the frequency of the compressor returns to the frequency before the air volume change at a speed of 10Hz/s. At the same time, the speed of the indoor fan increases slowly at a speed of 10n/s. During the speed-up process, the position of the guide plate remains unchanged until the wind speed corresponding to the speed is the wind speed indicated by the command, and the speed of the indoor fan is controlled to stop increasing.
