Fig. 1 is a flowchart illustrating a control method for an air conditioning system according to an exemplary embodiment. The method comprises the following steps:
step S101, under the self-cleaning mode, obtaining a mode switching control instruction containing a mode type.
And step S102, analyzing the mode switching control instruction to obtain the mode type.
Step S103, when the mode type is a self-cleaning mode, maintaining the current running state; otherwise, the rotating speed of the indoor fan is reduced and/or the air deflector is controlled to avoid air supply of a user.
In the self-cleaning process of the air conditioning system, the running state of the air conditioning system is different from the running state in a refrigerating mode or the running state in a heating mode, and the self-cleaning mode comprises the following steps: frosting mode and defrosting stage. Specifically, in the frosting stage, the operating frequency of the air conditioning system, the opening of the throttling device and the rotating speed of the indoor fan are adjusted, so that the evaporation temperature of the indoor heat exchanger or the outdoor heat exchanger to be cleaned is kept within a preset range, and the surface of the indoor heat exchanger or the outdoor heat exchanger is frosted. And in the defrosting stage, the operating frequency of the air conditioning system, the opening of the throttling device and the rotating speed of the outdoor fan are adjusted, so that the surface condensation temperature of the indoor heat exchanger or the outdoor heat exchanger is kept within a preset range, and the surface of the indoor heat exchanger or the outdoor heat exchanger is defrosted.
In step S101, after acquiring a mode switching control command including a mode type in the self-cleaning mode, step S102 is executed to analyze the mode switching control command to acquire the mode type. Wherein the mode types include: a cooling mode, a heating mode, and a self-cleaning mode. When the self-cleaning mode is not completely started again after the self-cleaning mode is finished due to more dust on the surface of the heat exchanger, the conventional running state of the current self-cleaning mode is maintained. When the received mode switching control instruction comprises a refrigerating mode or a heating mode, discomfort caused by strong hot air or strong cold air blown out due to overhigh or overlow surface temperature of the indoor heat exchanger to a user is avoided in the air supply process, the rotating speed of the indoor fan is reduced or the air deflector is controlled to avoid air supply of the user or the rotating speed of the indoor fan is reduced and the air deflector is controlled to avoid air supply of the user.
In the embodiment of the invention, the mode switching control instruction containing the mode type is obtained in the self-cleaning mode, and when the air conditioning system is determined to be switched to other modes, the indoor fan and the air deflector are adjusted, so that the rotating speed of the indoor fan is reduced or the air deflector is controlled to avoid the air supply of a user, the large temperature fluctuation caused by strong cold air or strong hot air blown out by the air conditioning system is avoided, and the user experience is reduced.
In some optional embodiments, the air conditioning control method provided by the foregoing embodiments is executed by a processor of an air conditioning system. Specifically, the method comprises the following steps:
and under the self-cleaning mode, the processor acquires a mode switching control instruction containing a mode type.
And the processor analyzes the mode switching control instruction to obtain the mode type.
The processor is used for maintaining the current running state when the mode type is the self-cleaning mode; otherwise, the rotating speed of the indoor fan is reduced and/or the air deflector is controlled to avoid air supply of a user.
In some alternative embodiments, as shown in fig. 2, a flowchart of a control method for an air conditioning system is shown according to an exemplary embodiment. The method comprises the following steps:
step S201, in the self-cleaning mode, a mode switching control instruction including a mode type is obtained.
Step S202, analyzing the mode switching control instruction to obtain the mode type.
Step S203, when the mode type is a self-cleaning mode, maintaining the current running state; otherwise, the rotating speed of the indoor fan is reduced and/or the air deflector is controlled to avoid air supply of a user.
And step S204, acquiring the air-conditioning target temperature and the indoor environment temperature.
And S205, when the absolute value of the difference value obtained by subtracting the air-conditioning target temperature from the indoor environment temperature is less than the set temperature, adjusting the rotating speed of the indoor fan and the position of the air deflector according to the mode type.
In step S204, when the target temperature of the air conditioner and the target temperature of the indoor environment are close to each other, the operation state of the air conditioning system is relatively stable, specifically, the difference value obtained by subtracting the target temperature of the air conditioner from the target temperature of the indoor environment is determined according to step S205, whether the target temperature of the air conditioner is close to the indoor environment is determined according to the absolute value of the difference value and the set temperature, when the absolute value of the difference value is smaller than the set temperature, the target temperature of the air conditioner is close to the indoor environment, and at this time, the rotating speed of the indoor fan and the position of the air deflector are adjusted according to the mode type. Specifically, the rotating speed of the indoor fan and the position of the air deflector are adjusted according to the target temperature of the air conditioner, and the rotating speed of the indoor fan and the position of the air deflector of the air conditioning system are adjusted according to a conventional control process of the air conditioning system.
Optionally, the set temperature is 1-3 ℃. Preferably, the set temperature is 1 ℃, 2 ℃ or 3 ℃.
In some optional embodiments, in step S103 or step S203, the reducing the indoor fan speed and/or controlling the air deflector to avoid the air supply of the user includes:
the method comprises the steps of obtaining the current indoor fan rotating speed of an air conditioning system, and when the indoor fan rotating speed is high, controlling the indoor fan to operate at a medium speed or a low speed and controlling an air deflector to avoid air supply of a user; when the rotating speed of the indoor fan is medium, controlling the indoor fan to operate at a low speed and controlling the air deflector to avoid air supply of a user; and when the rotating speed of the indoor fan is low, the air deflector is controlled to avoid air supply of a user.
In the foregoing embodiments, there are various ways to control the air deflector to avoid the air supply of the user.
In some alternative embodiments, controlling the air deflection plate to avoid the user supply air comprises: and controlling the air deflector to be opened to an upward horizontal angle. In the prior art, the air-conditioning air deflector is arranged in parallel to the ground, and the air deflector is opened to a horizontal angle on the upper side, so that the situation that wind guided out by the air deflector is directly blown to a user can be avoided, and the user experience is improved.
In some alternative embodiments, controlling the air deflection plate to avoid the user supply air comprises: acquiring image information of an environment where an air conditioner is located; and when the image information contains a target object, controlling the air deflector to avoid air supply of the target object.
The method comprises the steps that image information of the environment where the air conditioner is located, namely the image information in the temperature adjusting range of the indoor unit of the air conditioner, whether a user moves in the adjusting range of the indoor unit of the air conditioner or not is determined according to the image information, and if the user is determined to be in the adjusting range of the indoor unit of the air conditioner, the air deflector is controlled to avoid air supply of the user. In some optional embodiments, the air guiding plate includes a horizontal air guiding plate and a vertical air guiding plate, and in order to ensure that the air guiding plate avoids the air supplied by the user, the vertical air guiding plate may be controlled to open to a set angle, and the horizontal air guiding plate swings up and down, for example: the user moves in the left side range of the air conditioner installation position, the vertical air guide plate is controlled to be opened to the middle or the position of the middle on the left side, and the horizontal air guide plate swings up and down, so that the air supply range is enlarged while the condition that air outlet of the air conditioner cannot blow the user directly is ensured.
When the outdoor heat exchanger is cleaned and the self-cleaning process is finished, the surface temperature of the indoor heat exchanger is lower, and when the air conditioner is switched from the self-cleaning mode to other modes, the air outlet temperature of the indoor unit of the air conditioner is lower. When the indoor heat exchanger is cleaned and the self-cleaning process is finished, the surface temperature of the indoor heat exchanger is high, and when the air conditioner is switched from the self-cleaning mode to other modes, the air outlet temperature of the indoor unit of the air conditioner is high. Compared with the strong cold air blown out from the air outlet, the strong hot air only influences the body sensing temperature of the user and does not cause harm to the human body, and the strong cold air can cause cold or body ache of the user. Especially, it should be noted that when the air conditioning system operates in the cooling mode, in order to ensure that the indoor environment temperature meets the user requirement, the air conditioning system may blow cold air indoors, if the outdoor heat exchanger is cleaned, the surface temperature of the indoor heat exchanger is low when the self-cleaning process is finished, at this time, the operating parameters of the air conditioner operate according to the normal cooling mode, and the air outlet temperature of the indoor unit of the air conditioner is lower than the air outlet temperature of the normal cooling mode.

And step S303, when the mode type is a refrigeration mode, reducing the rotating speed of the indoor fan and/or controlling the electric heating device to be started.
In some optional embodiments, in step S303, when the mode type included in the obtained mode switching control instruction is the cooling mode, discomfort caused by strong cold air blown by the indoor unit to a human body is avoided, and the rotation speed of the indoor fan is reduced. In this embodiment, the air conditioning system includes an electric heating device disposed in the indoor unit, and in some alternative embodiments, the electric heating device is controlled to be turned on to prevent discomfort caused by strong cold air blown from the indoor unit to a human body.
In the embodiment of the invention, the mode switching control instruction containing the mode type is obtained in the self-cleaning mode, and when the air conditioning system is determined to be switched to the refrigeration mode, the indoor fan and the electric heating device are adjusted, so that the rotating speed of the indoor fan is reduced or the electric heating device is controlled to be started, strong cold air blown by the air conditioning system is avoided, discomfort and large temperature fluctuation caused to a human body are avoided, and the user experience is improved.
In some optional embodiments, the air conditioning control method provided by the foregoing embodiments is executed by a processor of an air conditioning system. Specifically, the method comprises the following steps:
and under the self-cleaning mode, the processor acquires a mode switching control instruction containing a mode type.
And the processor analyzes the mode switching control instruction to obtain the mode type.
And the processor is used for reducing the rotating speed of the indoor fan and/or controlling the electric heating device to be started when the mode type is the cooling mode.
In some alternative embodiments, as shown in fig. 4, a flowchart of a control method for an air conditioning system is shown according to an exemplary embodiment. The method comprises the following steps:

In the cooling mode, when the air conditioner runs in the self-cleaning process, the cooling requirement cannot be met, the indoor environment temperature can gradually rise, and the difference value of the indoor environment temperature minus the target temperature of the air conditioner is larger and larger along with the self-cleaning process. In step S401, in the self-cleaning mode, a mode switching control instruction including a mode type is obtained, when the mode switching control instruction is analyzed in step S402 and the mode type is determined to be the cooling mode, the rotation speed of the indoor fan is reduced or the electric heating device is controlled to be turned on or the rotation speed of the indoor fan is reduced and the electric heating device is controlled to be turned on, other operation parameters of the air conditioning system are controlled to operate according to the normal cooling mode, and the indoor environment temperature is gradually reduced to meet the user requirement. In step S404, an air-conditioning target temperature and an indoor environment temperature are obtained, when a difference value obtained by subtracting the air-conditioning target temperature from the indoor environment temperature is less than or equal to a set temperature difference, the indoor environment temperature approaches the air-conditioning target temperature, at this time, a refrigerating capacity of the air-conditioning system is reduced, an outlet air temperature is gradually increased, step S405 is executed to adjust a rotation speed of the indoor fan according to the mode type, that is, the rotation speed of the indoor fan is adjusted according to a conventional refrigerating mode control process, and an electric heating device is controlled to be turned off, so that the refrigerating effect is prevented from being affected.
Optionally, the temperature difference is set to be 1-5 ℃. In order to improve the speed of regulating the indoor environment temperature and accelerate the indoor environment temperature to meet the user requirement, the set temperature difference is not suitable to be too small. Preferably, the temperature difference is set to 3 ℃, 4 ℃ or 5 ℃.
In some optional embodiments, to avoid the surface temperature of the indoor heat exchanger being low, and to extend the time of the cooling mode operating according to the conventional control process, and further increase the cooling efficiency of the air conditioning system, before adjusting the rotation speed of the indoor fan and controlling the electric heating device to be turned off, the method further includes: and when the difference value obtained by subtracting the air-conditioning target temperature from the indoor environment temperature is greater than the set temperature difference value, adjusting the heating grade of the electric heating device according to the difference value.
Optionally, the heating level comprises: high-level and low-level. When the difference between the difference obtained by subtracting the target air-conditioning temperature from the indoor environment temperature and the set temperature difference is larger than a set value, the difference between the indoor environment temperature and the target air-conditioning temperature is large, and the operation parameters of the air-conditioning system need to be adjusted as soon as possible according to a conventional refrigeration mode control process, so that the surface temperature of the indoor heat exchanger needs to be adjusted as soon as possible, and the heating grade of the electric heating device is adjusted to be high.

Step S502, analyzing the mode switching control instruction to obtain the mode type.
Step S503, when the mode type is the self-cleaning mode, maintaining the current running state; otherwise, the indoor fan is controlled to operate at the first set rotating speed.
In the self-cleaning process of the air conditioning system, the running state of the air conditioning system is different from the running state in a refrigerating mode or the running state in a heating mode, and the self-cleaning mode comprises the following steps: frosting mode and defrosting stage. Specifically, in the frosting stage, the operating frequency of the air conditioning system, the opening of the throttling device and the rotating speed of the indoor fan are adjusted, so that the evaporation temperature of the indoor heat exchanger or the outdoor heat exchanger to be cleaned is kept within a preset range, and the surface of the indoor heat exchanger or the outdoor heat exchanger is frosted. And in the defrosting stage, the operating frequency of the air conditioning system, the opening of the throttling device and the rotating speed of the outdoor fan are adjusted, so that the surface condensation temperature of the indoor heat exchanger or the outdoor heat exchanger is kept within a preset range, and the surface of the indoor heat exchanger or the outdoor heat exchanger is defrosted.
In step S501, after acquiring a mode switching control command including a mode type in the self-cleaning mode, step S502 is executed to analyze the mode switching control command to acquire the mode type. Wherein the mode types include: a cooling mode, a heating mode, and a self-cleaning mode. When the self-cleaning mode is not completely started again after the self-cleaning mode is finished due to more dust on the surface of the heat exchanger, the conventional running state of the current self-cleaning mode is maintained. When the received mode switching control instruction comprises a refrigerating mode or a heating mode, discomfort brought to users due to strong hot air or strong cold air blown out due to overhigh or overlow surface temperature of the indoor heat exchanger in the air supply process is avoided, the air output of the indoor unit of the air conditioner needs to be reduced, and specifically, the indoor fan is controlled to operate at a first set rotating speed so as to avoid the indoor unit of the air conditioner from blowing out strong cold air or strong hot air. It will be appreciated that the first set speed is less than the speed of the indoor fan in the self-cleaning mode.
In the embodiment of the invention, the mode switching control instruction containing the mode type is obtained in the self-cleaning mode, and when the air conditioning system is determined to be switched to other modes, the indoor fan is controlled to operate at the first set rotating speed, so that the setting avoids that the air conditioning system blows out strong cold air or strong hot air to cause large temperature fluctuation and reduce user experience.

The indoor fan runs at a mute rotating speed, so that the air output of the indoor unit can be reduced, the indoor unit of the air conditioner is prevented from blowing out strong cold air or strong hot air, and the noise of the air conditioning system can be reduced.
In some optional embodiments, the air conditioning control method provided by the foregoing embodiments is executed by a processor of an air conditioning system. Specifically, the method comprises the following steps:
and under the self-cleaning mode, the processor acquires a mode switching control instruction containing a mode type.
And the processor analyzes the mode switching control instruction to obtain the mode type.

Step S603, when the mode type is a self-cleaning mode, maintaining the current running state; otherwise, the indoor fan is controlled to operate at the first set rotating speed.
And step S604, acquiring the target temperature of the air conditioner and the indoor environment temperature after the air conditioning system operates at the first set rotating speed for a set first time period.
Step S605, when the difference value of the indoor environment temperature minus the air-conditioning target temperature is larger than or equal to the set temperature difference, controlling the air-conditioning system to operate at the second set rotating speed; and when the difference value obtained by subtracting the air-conditioning target temperature from the indoor environment temperature is smaller than the set temperature difference, controlling an air-conditioning system to adjust the rotating speed of an indoor fan according to the mode type.
In step S603, the indoor fan is controlled to operate at a first set rotational speed, the first set rotational speed is low, and in order to avoid blowing out strong cold air or strong hot air due to the surface temperature of the indoor unit in a short time after exiting from the self-cleaning mode, and to ensure the adjustment of the indoor temperature by the air conditioning system, the rotational speed of the indoor fan needs to be increased after the indoor fan operates at the first set rotational speed for a period of time. Specifically, in step S604, after the air conditioning system operates at the first set rotational speed for a set first duration, the air conditioning target temperature and the indoor environment temperature are obtained, and in step S605, the rotational speed of the indoor fan is increased according to the air conditioning target temperature and the indoor environment temperature.
In step S605, when the target temperature of the air conditioner is close to the target temperature of the indoor environment, the operating state of the air conditioning system is relatively stable, and the air conditioning system is controlled to adjust the rotating speed of the indoor fan according to the mode type, that is, when the difference between the target temperature of the air conditioner and the indoor environment temperature is smaller than the set temperature difference, the air conditioning system is controlled to adjust the rotating speed of the indoor fan according to the mode type. And when the difference value obtained by subtracting the target temperature of the air conditioner from the indoor environment temperature is greater than or equal to the set temperature difference, the rotating speed of the indoor fan is properly increased, and specifically, the air conditioning system is controlled to operate at the second set rotating speed. Wherein the second set rotating speed is greater than the first set temperature.
Optionally, the temperature difference is set to be 1-3 ℃. Preferably, the temperature difference is set to 1 ℃, 2 ℃ or 3 ℃.
