[0041] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0042] The air conditioner 100 and its control method, control device and storage medium according to embodiments of the present invention will be described below with reference to the accompanying drawings.

[0043] like Figures 1-5 As shown, the air conditioner 100 according to an embodiment of the present invention includes an air outlet 102 and an air guide assembly 50. The air guide assembly 50 is movably disposed at the air outlet 102. The air outlet direction can be changed by using the air guide assembly 50. The air conditioner 100 has an anti-direct-blow mode. In the anti-direct-blow mode, the air outlet 102 of the air conditioner 100 can form a two-sided airflow pattern, thereby avoiding the user located directly in front of the air outlet 102.

[0044] The air conditioner 100 also has a forward blowing mode, a left-side blowing mode, and a right-side blowing mode. In the forward blowing mode, the air outlet 102 of the air conditioner 100 can form a central blowing pattern. In the left-side blowing mode, the air outlet 102 of the air conditioner 100 can form a left-side blowing pattern. In the right-side blowing mode, the air outlet 102 of the air conditioner 100 can form a right-side blowing pattern.

[0045] Specifically, the air guide assembly 50 is located at the air outlet 102. When in the closed state, the air guide assembly 50 closes a portion of the air outlet 102. The air guide assembly 50 includes a first air guide 51 and a second air guide 52, which are arranged in a left-right direction and are both movable. That is, the first air guide 51 and the second air guide 52 do not affect each other during movement; they can be driven by different drive components. This allows for separate control of the first air guide 51 and the second air guide 52 as needed, achieving different blowing modes through their cooperation.

[0046] like Figure 6 As shown, the control method for an air conditioner according to an embodiment of the present invention includes the following steps:

[0047] S1: When the air conditioner's anti-direct-blow mode is turned on, obtain the indoor ambient temperature; that is, when entering the anti-direct-blow mode, obtain the air intake temperature of the air conditioner.

[0048] S2: controlling the rotating speed of the indoor fan according to the indoor environment temperature to coarsely adjust the air volume of the air conditioner;

[0049] Considering the complexity of the indoor space layout, even if the air volume changes a little, the user may experience the back temperature phenomenon in actual use. In order to further avoid the back temperature phenomenon, the operation parameters of the air conditioner can be further adjusted. Specifically, the control method of the air conditioner further comprises:

[0050] S3: controlling the rotating speed of the indoor fan and the operation frequency of the compressor according to the indoor environment temperature after a preset time to finely adjust the air volume of the air conditioner.

[0051] According to the control method of the air conditioner, when the anti-direct blowing mode is started, the operation parameters of the indoor fan and the compressor are adjusted according to the indoor environment temperature, so that the air volume of the air conditioner is changed in real time, the back temperature phenomenon after switching from other blowing modes to the anti-direct blowing mode is improved, and the user experience is improved.

[0052] As shown in Figure 6 and Figure 7 According to some embodiments of the present application, when the air conditioner is in cooling operation, the rotating speed of the indoor fan is controlled according to the indoor environment temperature, comprising:

[0053] When the indoor environment temperature is less than or equal to the set temperature, the rotating speed of the indoor fan is controlled to be the same as the air volume before entering the anti-direct blowing mode.

[0054] When the indoor environment temperature is greater than the set temperature, the indoor fan is controlled to operate at a first preset rotating speed.

[0055] Specifically, when the user presses the anti-direct blowing button, the air conditioner determines whether to enter or exit the anti-direct blowing mode according to the current blowing mode, and then determines the current working mode.

[0056] When the current working mode of the air conditioner is the cooling mode, it is determined whether the current indoor environment temperature T of the air conditioner meets the set condition, so as to adjust the operation parameters of the indoor fan and the compressor according to the determination result. The set condition here is whether the set temperature T0 is reached, and T0 is the user set temperature.

[0057] If the current indoor environment temperature T meets the set condition, that is, the current indoor environment temperature T is greater than the set temperature T0, the air conditioner controls the indoor fan to operate at a fixed rotating speed (the first preset rotating speed), and the first preset rotating speed can be the maximum rotating speed V 3,max .

[0058] If the current indoor environment temperature T does not satisfy the set condition, that is, the current indoor environment temperature T is less than or equal to the set temperature T0, the air conditioner controls the indoor fan to operate at a variable rotating speed, so that the current air volume of the air conditioner is the same as that of the previous blowing mode by changing the rotating speed of the indoor fan, thereby avoiding the temperature return phenomenon after switching from the previous blowing mode to the anti-direct blowing mode, and improving the user experience.

[0059] It should be noted that when the air conditioner controls the indoor fan to operate at a fixed rotating speed, other operating parameters remain unchanged; when the air conditioner controls the indoor fan to operate at a variable rotating speed, the indoor fan first operates at the rotating speed corresponding to the same air volume as the previous blowing mode, and then is gradually adjusted, and if the rotating speed corresponding to the same air volume as the previous blowing mode is greater than the maximum rotating speed in the anti-direct blowing mode, the indoor fan operates at the maximum rotating speed in the anti-direct blowing mode.

[0060] According to a further embodiment of the present application, when the target rotating speed is greater than the first preset rotating speed, the indoor fan is controlled to operate at the first preset rotating speed.

[0061] When the air conditioner controls the indoor fan to operate at a variable rotating speed, the specific adjustment process is as follows:

[0062] S21: controlling the indoor fan to operate at the rotating speed corresponding to the same air volume as the previous blowing mode;

[0063] S22: gradually changing the current rotating speed V of the indoor fan according to the rotating speed relationship of the indoor fan 3local ,

[0064] The rotating speed relationship is V 3local = V*k+b, where k and b are the relationship coefficients of the current rotating speed V 3local of the indoor fan and the previous blowing mode, which are determined by the air volume-rotating speed curve of the anti-direct blowing mode and the previous blowing mode at the same air volume.

[0065] It should be noted that when the previous blowing mode is the forward blowing mode, the left blowing mode or the right blowing mode, the coefficients k and b can be different, for example, when the previous blowing mode is the forward blowing mode, the coefficients k and b are k1 and b1 respectively, when the previous blowing mode is the left blowing mode, the coefficients k and b are k2 and b2 respectively, and when the previous blowing mode is the right blowing mode, the coefficients k and b are k3 and b3 respectively.

[0066] For example, Figure 6 and Figure 8As shown, in some embodiments, the speed of the indoor fan and the operating frequency of the compressor are controlled according to the indoor ambient temperature, including:

[0067] When the indoor ambient temperature is less than or equal to the set temperature, first reduce the compressor's operating frequency, then reduce the indoor fan speed; when the indoor ambient temperature is greater than the set temperature, first increase the indoor fan speed, then increase the compressor's operating frequency.

[0068] When the air conditioner is in cooling mode, it switches from the previous blowing mode to anti-direct blowing mode. After a preset time Δt for coarse adjustment, the air volume of the air conditioner is finely adjusted.

[0069] Considering that the fan speed in the anti-direct-blow mode is generally lower than in other modes when the air conditioner is in cooling mode, in order to ensure that the cooling capacity can still be delivered to the room despite the influence of gravity, the fine-tuning control steps are set as follows. Specifically, the fine-tuning control steps are:

[0070] S31: Detect whether the current indoor ambient temperature meets the preset conditions, that is, whether the indoor ambient temperature is greater than the set temperature;

[0071] S32: If the indoor ambient temperature is less than or equal to the set temperature, the air volume of the air conditioner will be gradually reduced in the order of first reducing the operating frequency of the compressor and then reducing the speed of the indoor fan to achieve energy saving; if the indoor ambient temperature is greater than the set temperature, the air volume of the air conditioner will be gradually increased in the order of first increasing the fan speed and then increasing the frequency of the compressor to increase the cooling capacity and lower the indoor temperature.

[0072] Specifically, such as Figure 11 As shown, if the indoor ambient temperature T is less than or equal to the set temperature T0, determine the current operating frequency f of the compressor. 3local Is this the minimum value in anti-direct-blow mode, when the compressor's current operating frequency f 3local Not equal to the minimum value f in the anti-direct-blow mode 3min Then maintain the current speed V of the indoor fan. 3local The operating frequency f of the compressor remains unchanged to prevent direct blowing mode. 3local’ Run for a preset time Δt, then check again whether the indoor ambient temperature T meets the preset condition, and repeat the following steps. The compressor's operating frequency is expressed by the relationship f. 3local’ =f 3local -Δf is adjusted; when the compressor's current operating frequency f 3local The minimum value f in the anti-direct-blow mode 3min At that time, determine the current speed V of the indoor fan. 3local Is this the minimum value V in the anti-direct-blow mode? 3min When the current speed V of the indoor fan3local is the minimum value in the direct blowing mode 3min , the air conditioner controls the compressor to run at the current operating frequency f 3local , and controls the indoor fan to run at the current rotating speed V 3local . When the current rotating speed V 3local of the indoor fan is not equal to the minimum value V 3min in the direct blowing mode, the current operating frequency f 3local of the compressor remains unchanged, and the indoor fan is controlled to run at the rotating speed V 3local’ adjusted in the direct blowing mode for a preset time Δt, and then the indoor environment temperature T is judged again to see if it meets the preset condition, and the following steps are repeated, wherein the rotating speed of the indoor fan is adjusted according to the relationship V 3local’ = V 3local - ΔV.

[0073] When the indoor environment temperature T is greater than the set temperature T0, it is judged whether the current rotating speed V 3max of the indoor fan is the maximum value V 3local in the direct blowing mode. When the current rotating speed V 3max of the indoor fan is not equal to the maximum value V 3local in the direct blowing mode, the current operating frequency f 3local’ of the compressor remains unchanged, and the indoor fan is controlled to run at the rotating speed V 3local’ adjusted in the direct blowing mode for a preset time Δt, and then the indoor environment temperature T is judged again to see if it meets the preset condition, and the following steps are repeated, wherein the rotating speed of the indoor fan is adjusted according to the relationship V 3local = V 3local + ΔV; and when the current rotating speed V 3max of the indoor fan is the maximum value V 3local in the direct blowing mode, it is judged whether the current operating frequency f 3max of the compressor is the maximum value f 3local in the direct blowing mode. When the current operating frequency f 3max of the compressor is the maximum value f 3local in the direct blowing mode, the air conditioner controls the compressor to run at the current operating frequency f 3local , and controls the indoor fan to run at the current rotating speed V 3local . When the current operating frequency f 3max of the compressor is not equal to the maximum value f 3local’ in the direct blowing mode, the rotating speed of the indoor fan remains unchanged, and the compressor is controlled to run at the operating frequency f 3local’ adjusted in the direct blowing mode for a preset time Δt, and then the indoor environment temperature T is judged again to see if it meets the preset condition, and the following steps are repeated, wherein the operating frequency of the compressor is adjusted according to the relationship f 3local+ Δf is adjusted.

[0074] wherein ΔV is the interval of the speed of the indoor fan when increasing or decreasing, Δf is the interval of the running frequency of the compressor when increasing or decreasing, the maximum value V 3max is greater than the maximum value V max .

[0075] As shown in Figure 6 and Figure 9 , according to some embodiments of the present application, when the air conditioner is in heating operation, the speed of the indoor fan is controlled according to the indoor environment temperature, comprising:

[0076] when the indoor environment temperature is greater than or equal to the set temperature, the indoor fan is controlled in variable speed to make the current air volume of the air conditioner the same as that before entering the anti-direct blowing mode;

[0077] when the indoor environment temperature is less than the set temperature, the indoor fan is controlled to run at the first preset speed.

[0078] Similarly, when the current working mode of the air conditioner is the heating mode, it is judged whether the current indoor environment temperature of the air conditioner meets the set condition, so as to adjust the running parameters of the indoor fan and the compressor according to the judgment result. Wherein the set condition here is whether less than the set temperature.

[0079] If the current indoor environment temperature meets the set condition, i.e. the indoor environment temperature is less than the set temperature, the air conditioner controls the indoor fan to run at a fixed speed (the first preset speed), and the first preset speed here can be the maximum speed of the indoor fan when the air conditioner is in the anti-direct blowing mode.

[0080] If the current indoor environment temperature does not meet the set condition, i.e. the indoor environment temperature is greater than or equal to the set temperature, the air conditioner controls the indoor fan to run in variable speed, so as to make the current air volume of the air conditioner the same as that of the previous blowing mode by changing the running speed of the indoor fan, thereby avoiding the temperature return phenomenon after switching from the previous blowing mode to the anti-direct blowing mode, and improving the user experience.

[0081] It should be noted that when the air conditioner controls the indoor fan to run at a fixed speed, other running parameters remain unchanged, and when the air conditioner controls the indoor fan to run in variable speed, the indoor fan first runs at the speed under the same air volume as the previous blowing mode, and then gradually adjusts, and if the speed under the same air volume as the previous blowing mode is greater than the maximum speed in the anti-direct blowing mode, it can run at the maximum speed in the anti-direct blowing mode.

[0082] When the air conditioner is in the heating mode, the specific adjustment process is similar to the adjustment process when the air conditioner is in the cooling mode, which will not be described here again.

[0083] As shown in Figure 6 and Figure 10 , in some embodiments, the speed of the indoor fan and the operating frequency of the compressor are controlled according to the indoor environment temperature, including:

[0084] When the indoor environment temperature is greater than or equal to the set temperature, first reduce the operating frequency of the compressor, and then reduce the speed of the indoor fan; when the indoor environment temperature is less than the set temperature, first increase the speed of the indoor fan, and then increase the operating frequency of the compressor.

[0085] When the working mode of the air conditioner is the heating mode, the air conditioner is switched from the last blowing mode to the anti-direct blowing mode, and the air volume of the air conditioner is adjusted after a preset time Δt. Considering that the air speed in the anti-direct blowing mode is generally lower than that in other modes when the air conditioner is in the heating mode, in order to ensure that heat can still be delivered to the indoor under the influence of gravity, the control steps of fine adjustment are set as follows.

[0086] Specifically, the control steps of fine adjustment are:

[0087] S31: Detect whether the current indoor environment temperature meets the preset condition, that is, whether the indoor environment temperature is greater than the set temperature;

[0088] S32: If the indoor environment temperature is greater than the set temperature, gradually reduce the air volume of the air conditioner in the order of first reducing the operating frequency of the compressor and then reducing the speed of the indoor fan to achieve the purpose of energy saving; if the indoor environment temperature is less than or equal to the set temperature, gradually increase the air volume of the air conditioner in the order of first increasing the speed of the fan and then increasing the frequency of the compressor, so as to increase the heat and raise the indoor temperature.

[0089] Specifically, as shown in Figure 12 , if the indoor environment temperature T is greater than or equal to the set temperature T0, it is judged whether the current operating frequency f 3local of the compressor is the minimum value in the anti-direct blowing mode, when the current operating frequency f 3local of the compressor is not equal to the minimum value f 3min in the anti-direct blowing mode, the current speed V 3local of the indoor fan is kept unchanged, the compressor is controlled to operate at the adjusted operating frequency f 3local’ in the anti-direct blowing mode for a preset time Δt, and then it is judged again whether the indoor environment temperature T meets the preset condition, and the following steps are repeated, wherein the operating frequency of the compressor is f 3local’ = f 3local-Δf is adjusted; when the compressor's current operating frequency f 3local The minimum value f in the anti-direct-blow mode 3min At that time, determine the current speed V of the indoor fan. 3local Is this the minimum value V in the anti-direct-blow mode? 3min When the current speed V of the indoor fan 3local Minimum value V in anti-direct-blow mode 3min At that time, the air conditioner controls the compressor to operate at the current frequency f. 3local And, control the indoor fan to operate at the current speed V 3local When the indoor fan is running, at its current speed V 3local Not equal to the minimum value V in the anti-direct-blow mode 3min When this happens, the compressor's current operating frequency f is maintained. 3local The indoor fan speed remains unchanged after adjustment to prevent direct airflow. 3local’ Run for a preset time Δt, then check again whether the indoor ambient temperature T meets the preset condition, and repeat the following steps. The indoor fan speed is determined by the relationship V... 3local’ =V 3local -ΔV is adjusted.

[0090] If the indoor ambient temperature T is less than the set temperature T0, determine whether the current speed V3local of the indoor fan is the maximum value V in the anti-direct-blow mode. 3max When the current speed V of the indoor fan 3local Not equal to the maximum value V in anti-direct-blow mode 3max Then maintain the compressor's current operating frequency f. 3local The indoor fan speed V remains unchanged after adjustment to prevent direct airflow. 3local’ Run for a preset time Δt, then check again whether the indoor ambient temperature T meets the preset condition, and repeat the following steps. The indoor fan speed is determined by the relationship V... 3local’ =V 3local Adjust by +ΔV; when the current speed V of the indoor fan... 3local The maximum value V in anti-direct-blow mode 3max At that time, determine the current operating frequency f of the compressor. 3local Is this the maximum value f in anti-direct-blow mode? 3max When the compressor's current operating frequency f 3local The maximum value f in anti-direct-blow mode 3max At that time, the air conditioner controls the compressor to operate at the current frequency f. 3local And, control the indoor fan to operate at the current speed V 3local When the compressor is running at its current operating frequency f 3local Not equal to the maximum value f in anti-direct-blow mode 3maxWhen the indoor environment temperature T meets the preset condition, the rotational speed of the indoor fan is kept unchanged, and the compressor is controlled to adjust the operating frequency f 3local’ for a preset time Δt, and then it is judged again whether the indoor environment temperature T meets the preset condition, and the following steps are repeated, wherein the operating frequency of the compressor is adjusted according to the relationship f 3local’ =f 3local +Δf.
