[0073] Based on the hardware architecture of the above-mentioned air conditioner control device, an embodiment of the air conditioner control method of the present invention is proposed.

[0074] Reference Figure 2 , Figure 2 The first embodiment of the air conditioner control method of the present invention comprises the following steps:

[0075] Step S10, determining the air outlet direction according to the current rotation speed of the indoor fan, wherein the angle between the air outlet direction and the direct blowing prevention direction is positively correlated with the current rotation speed.

[0076] Optionally, the current rotation speed of the indoor fan may be acquired based on sensor data.

[0077] Optionally, the current rotation speed of the indoor fan may be determined according to the current windshield, wherein the windshield includes a high windshield, a middle windshield and a low windshield, and each windshield corresponds to a preset fan rotation speed.

[0078] Optionally, the current speed of the indoor fan can be determined based on the current windshield, where the windshield is a preset ratio of the maximum speed, for example, the current windshield is 50% of the maximum speed. Or the windshield is a preset ratio of the rated speed, for example, the current windshield is 60% of the rated speed.

[0079] Optionally, due to different settings of the wind guide device, the change of the wind outlet direction is different. Optionally, when the wind guide device is set in a vertical or horizontal direction, for example, the wind guide plate is perpendicular to the horizontal direction, the wind outlet direction can be changed in the horizontal direction; when the wind guide device is set in a horizontal direction, for example, the wind guide plate is set horizontally, the wind outlet direction can be changed in the vertical direction.

[0080] Optionally, the anti-direct blowing direction can be a user-set direction, or the anti-direct blowing direction is determined according to the user's location. Optionally, there is an angle between the air outlet direction of the air conditioner and the anti-direct blowing direction to avoid direct blowing on the human body. Optionally, the greater the current rotation speed, the greater the angle between the air outlet direction and the anti-direct blowing direction, so that the air outlet direction is away from the anti-direct blowing direction to avoid high wind speed blowing on the human body; the smaller the current rotation speed, the smaller the angle between the air outlet direction and the anti-direct blowing direction, so that the air outlet direction and the anti-direct blowing direction are in different directions to avoid direct blowing on the human body.

[0081] Optionally, when the current rotation speed is less than or equal to a preset rotation speed threshold, the angle between the air outlet direction and the anti-direct blowing direction is determined to be a preset first angle X1; when the current rotation speed is greater than the preset rotation speed threshold, the angle between the air outlet direction and the anti-direct blowing direction is determined to be a preset second angle X2, and the second angle X2 is greater than the first angle X1. Optionally, the preset rotation speed threshold may be a 50% windshield, that is, when the current rotation speed is less than or equal to 50% windshield, the angle between the air outlet direction and the anti-direct blowing direction is determined to be a preset first angle X1; when the current rotation speed is greater than 50% windshield, the angle between the air outlet direction and the anti-direct blowing direction is determined to be a preset second angle X2.

[0082] Optionally, before step S10, the method further includes: when the air conditioner is in a standby state, determining that the angle between the air outlet direction and the anti-direct blowing direction is a preset third angle, and the rotation speed of the indoor fan is a preset rotation speed; optionally, the preset third angle is the same as the preset second angle. Optionally, when the air conditioner is not in a standby state, executing steps S10 to S30.

[0083] Optionally, before step S10, it also includes: when receiving a control instruction from the user, controlling the air conditioner to turn on the anti-direct blowing function; or when it is detected that a human body exists in the air conditioner's action space and the existence time is greater than a preset time, controlling the air conditioner to turn on the anti-direct blowing function; after the anti-direct blowing function is turned on, executing the step of determining the air outlet direction according to the current speed of the indoor fan.

[0084] Step S20, determining a temperature difference between the indoor ambient temperature and the set temperature, and determining a rotation speed increment according to the temperature difference, wherein the temperature difference is positively correlated with the rotation speed increment.

[0085] Optionally, the temperature difference between the indoor ambient temperature and the set temperature is determined, wherein the larger the temperature difference, the larger the difference between the indoor ambient temperature in the air conditioner's working space and the set temperature. In order to ensure the operating effect of the air conditioner, a larger fan speed is required. Therefore, the larger the temperature difference, the larger the speed increment. The smaller the temperature difference, the smaller the difference between the indoor ambient temperature in the air conditioner's working space and the set temperature. At this time, the air conditioner has a good operating effect and does not require a larger fan speed. Therefore, the smaller the temperature difference, the smaller the speed increment of the indoor fan.

[0086] Optionally, when the current speed is greater than a preset speed threshold and the temperature difference is greater than a preset temperature threshold, the speed increment is determined to be a preset first speed value; when the current speed is greater than the preset speed threshold and the temperature difference is less than or equal to the preset temperature threshold, the speed increment is determined to be zero. Optionally, when the current speed is less than or equal to the preset speed threshold and the temperature difference is greater than the preset temperature threshold, the speed increment is determined to be a preset second speed value; when the current speed is less than or equal to the preset threshold and the temperature difference is less than or equal to the preset temperature threshold, the speed increment is determined to be zero.

[0087] Step S30, controlling the air conditioner to adjust the angle of the air guide device according to the air outlet direction, and adjusting the speed of the indoor fan according to the speed increment.

[0088] Optionally, the air guide device of the air conditioner can be an air guide plate, which can be arranged vertically or horizontally. The air conditioner is controlled to adjust the angle of the air guide device according to the air outlet direction so as to form an angle with the anti-direct blowing direction to avoid direct blowing to the human body.

[0089] Optionally, the speed of the indoor fan is adjusted according to the speed increment, and the speed of the indoor fan is determined according to the speed increment. The adjusted speed = current speed + speed increment to avoid sudden changes in heat or cold in the air conditioner's action space, which would cause large changes in the human body's perceived temperature.

[0090] Optionally, the temperature difference between the indoor ambient temperature and the set temperature is determined, and the compressor frequency is determined based on the temperature difference, wherein the temperature difference is positively correlated with the compressor frequency; the air conditioner is controlled to operate according to the compressor frequency to ensure that the heat or cold in the air conditioner's action space does not change suddenly, thereby maintaining the operating effect of the air conditioner.

[0091] In the technical solution of this embodiment, the air outlet direction is determined according to the current speed of the indoor fan, and the angle between the air outlet direction and the anti-direct blowing direction is positively correlated with the current speed; the temperature difference between the indoor ambient temperature and the set temperature is determined, and the speed increment is determined according to the temperature difference, and the temperature difference is positively correlated with the speed increment; the air conditioner is controlled to adjust the angle of the air guide device according to the air outlet direction, and the speed of the indoor fan is adjusted according to the speed increment. The air outlet direction is determined by the current speed of the indoor fan to prevent the air conditioner from blowing directly at the user, thereby improving the user's comfort experience when using the air conditioner, and the speed of the indoor fan is adjusted according to the temperature difference to avoid sudden changes in heat or cold in the air conditioner's action space while preventing direct blowing, thereby ensuring the operating effect of the air conditioner.

[0092] Reference Figure 3 , Figure 3 This is a second embodiment of the air conditioner control method of the present invention, based on the first embodiment, the step S20 includes:

[0093] Step S21, when the air conditioner operates in cooling mode, compare the temperature difference with a preset first temperature threshold, and determine the speed increment based on the comparison result; wherein, when the temperature difference is less than the preset first temperature threshold, the speed increment is determined to be zero; when the temperature difference is greater than or equal to the preset first temperature threshold, the speed increment is determined to be a preset speed value.

[0094] Optionally, the temperature difference Δt = indoor ambient temperature T1 - set temperature T sc Optionally, the first temperature threshold is preset as a set value, for example, the first temperature threshold is preset as 3°C. In cooling mode, before reaching the temperature, the temperature difference Δt is greater than zero. In cooling mode, if an over-temperature condition occurs, the temperature difference Δt is less than zero.

[0095] Optionally, when the temperature difference Δt is less than the preset first temperature threshold, if in cooling mode, the air conditioner may be in a state of about to reach the temperature, in a state of reaching the temperature, or in an over-temperature state, and there is no need to increase the speed of the indoor fan, so the speed increment of the indoor fan is determined to be zero; when the temperature difference Δt is greater than or equal to the preset first temperature threshold, if in cooling mode, the air conditioner is in a state of not reaching the temperature, so the speed increment of the indoor fan is determined to be the preset speed value.

[0096] Optionally, when the temperature difference Δt is less than zero, the air conditioner is in an over-temperature state. At this time, the speed increment can be determined to be zero, that is, the current wind speed of the indoor fan is maintained; the speed increment can also be determined to be a negative value, that is, the current wind speed of the indoor fan is reduced.

[0097] Optionally, the outdoor ambient temperature is obtained, and the ambient temperature difference between the indoor ambient temperature and the indoor ambient temperature is determined; the preset speed value is determined according to the temperature difference and the ambient temperature difference. Optionally, when the absolute value of the temperature difference is greater than a preset third temperature threshold, the greater the ambient temperature difference, the greater the preset speed value; when the absolute value of the temperature difference is less than or equal to the preset third temperature threshold, the smaller the ambient temperature difference, the smaller the preset speed value.

[0098] In the technical solution of this embodiment, when the air conditioner is running in cooling mode, the temperature difference is compared with the preset first temperature threshold, and the speed increment is determined according to the comparison result; wherein, when the temperature difference is less than the preset first temperature threshold, the speed increment is determined to be zero; when the temperature difference is greater than or equal to the preset first temperature threshold, the speed increment is determined to be the preset speed value. The speed of the indoor fan is adjusted according to the temperature difference to avoid sudden changes in the cooling capacity of the air conditioner's action space while preventing direct blowing, thereby ensuring the cooling effect of the air conditioner.

[0099] Reference Figure 4 , Figure 4 This is a third embodiment of the air conditioner control method of the present invention, based on the first or second embodiment, the step S20 includes:

[0100] Step S22, when the air conditioner runs in heating mode, compare the temperature difference with the preset second temperature threshold, and determine the speed increment according to the comparison result; wherein, when the temperature difference is greater than the preset second temperature threshold, the speed increment is determined to be zero; when the temperature difference is less than or equal to the preset second temperature threshold, the speed increment is determined to be the preset speed value.

[0101] Optionally, the temperature difference Δt = indoor ambient temperature T1 - set temperature T sc Optionally, the second temperature threshold is preset as a set value, for example, the second temperature threshold is preset as 3°C. In the heating mode, before reaching the temperature, the temperature difference Δt is less than zero. In the heating mode, if an over-temperature condition occurs, the temperature difference Δt is greater than zero.

[0102] Optionally, when the temperature difference Δt is greater than the preset second temperature threshold, if in heating mode, the air conditioner may be in a state of about to reach the temperature, in a state of reaching the temperature, or in an over-temperature state, and there is no need to increase the speed of the indoor fan, so the speed increment of the indoor fan is determined to be zero; when the temperature difference Δt is less than or equal to the preset second temperature threshold, if in heating mode, the air conditioner is in a state of not reaching the temperature, so the speed increment of the indoor fan is determined to be the preset speed value.

[0103] Optionally, when the temperature difference Δt is greater than zero, the air conditioner is in an over-temperature state. At this time, the speed increment can be determined to be zero, that is, the current wind speed of the indoor fan is maintained; the speed increment can also be determined to be a negative value, that is, the current wind speed of the indoor fan is reduced.

[0104] Optionally, the outdoor ambient temperature is obtained, and the ambient temperature difference between the indoor ambient temperature and the indoor ambient temperature is determined; the preset speed value is determined according to the temperature difference and the ambient temperature difference. Optionally, when the absolute value of the temperature difference is greater than a preset third temperature threshold, the greater the ambient temperature difference, the greater the preset speed value; when the absolute value of the temperature difference is less than or equal to the preset third temperature threshold, the smaller the ambient temperature difference, the smaller the preset speed value.

[0105] In the technical solution of this embodiment, when the air conditioner is running in heating mode, the temperature difference is compared with the preset second temperature threshold, and the speed increment is determined according to the comparison result; wherein, when the temperature difference is greater than the preset second temperature threshold, the speed increment is determined to be zero; when the temperature difference is less than or equal to the preset second temperature threshold, the speed increment is determined to be the preset speed value. The speed of the indoor fan is adjusted according to the temperature difference to avoid sudden changes in the heat of the air conditioner's action space while preventing direct blowing, thereby ensuring the heating effect of the air conditioner.

[0106] Reference Figure 5 , Figure 5 This is an embodiment of the control method of the air conditioner of the present invention. When the anti-direct blowing function of the air conditioner is turned on, the current operating state of the air conditioner is judged. If the operating state is standby, the air guide plate is directly moved to the anti-direct blowing angle X2, that is, the preset third angle, and the indoor fan runs at a preset speed, for example, 80% windshield.

[0107] If the running state is not the standby state, the windshield of the current indoor fan is determined. If the current indoor fan windshield Fan≤50%, the air guide plate is set to the anti-direct blowing angle X1, which is the preset first angle, where X2>X1. Then the temperature difference between the indoor ambient temperature T1 and the set temperature Tsc is determined. If it is less than or equal to the preset temperature threshold, such as 3°C, the current indoor fan windshield Fan is maintained to maintain the capacity output of the indoor environment. If it is greater than the preset temperature threshold, the indoor fan windshield is increased by the preset windshield Fan0 on the basis of the original windshield, where 10%≤Fan0≤30%, to avoid the air guide plate hitting the anti-direct blowing angle, which affects the capacity output and the user experience.

[0108] If the current indoor fan windshield Fan>50%, the wind guide plate will be set to the anti-direct blowing angle X2, which is the preset second angle, and then the temperature difference between the indoor ambient temperature T1 and the set temperature Tsc will be judged. If it is less than or equal to the preset temperature threshold, for example 3°C, the current indoor fan windshield will be maintained. If it is greater than the preset temperature threshold of 3°C, the indoor fan windshield will increase Fan1 on the basis of the original windshield, where 0%≤Fan1≤50%.

[0109] In the technical solution of this embodiment, the air outlet direction is determined by the current speed of the indoor fan to prevent the air conditioner from blowing directly onto the user, thereby improving the user's comfort experience when using the air conditioner. The speed of the indoor fan is adjusted according to the temperature difference to avoid sudden changes in heat or cooling in the air conditioner's working space while preventing direct blowing, thereby ensuring the operating effect of the air conditioner.
