Therefore, this application is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0025] This application provides an air conditioner control method to solve the problem that air conditioners cannot adaptively adjust airflow according to the user's location. The following description is in conjunction with the accompanying drawings.

[0026] Firstly, in the embodiments of this application, such as Figure 1 as well as Figure 5 As shown, the air conditioner control method includes an indoor unit of the air conditioner comprising a main body 1 and a grille 2. The main body 1 has an air outlet 11, and the grille 2 is installed on the main body 1 and can move closer to or further away from the air outlet 11 along the opening direction of the air outlet 11.

[0027] It should be noted that the indoor unit can be either a floor-standing or wall-mounted air conditioner unit; no limitation is made here. The opening direction of the air outlet 11 refers to the direction of extension of the side wall of the air outlet 11. The air delivery distance can be adjusted by moving the grille 2 along the opening direction of the air outlet 11. In some examples, there is a gap between the grille 2 and the side wall of the air outlet 11. When the grille 2 is pushed outward to the outside of the main unit 1, the airflow can not only be blown out through the grille 2 but also through the periphery of the grille 2.

[0028] like Figure 1 As shown, the air conditioner control method includes: S1: Obtain the distance between the user and the indoor unit.

[0029] Here, the distance between the user and the indoor unit refers to the horizontal straight-line distance between the user and the indoor unit, which is detected by sensors.

[0030] S2: Determine the target position of grille 2 based on the distance between the user and the indoor unit.

[0031] Knowing the distance between the user and the indoor unit, the target position of the grille 2 is determined accordingly, so as to facilitate subsequent control of the movement direction and stroke of the grille 2.

[0032] S3: Control the grille 2 to move to the target position to change the distance between the grille 2 and the air outlet 11.

[0033] After learning the target position of the grille 2, the control module controls the grille 2 to move. Based on the current position of the grille 2, the control module controls the grille 2 to move along the opening direction of the air outlet 11 to the target position in a way that is closer to or farther away from the air outlet 11.

[0034] Compared with related technologies, the air conditioner control method provided in this application embodiment can flexibly adjust the airflow characteristics of the indoor unit according to the user's position relative to the indoor unit, reducing the inconvenience caused by operation by remote control in related technologies, and truly achieving the purpose of intelligently changing the air supply mode of the indoor unit according to the user's activities.

[0035] In some embodiments, such as Figure 2 As shown, S2 determines the target position of the grille 2 based on the distance between the user and the indoor unit, and may include S21 to S23.

[0036] S21: Obtain the operating mode of the air conditioner.

[0037] S22: Determine the target adjustment parameters based on the operating mode.

[0038] The target adjustment parameters differ under different operating modes.

[0039] S23: Determine the target position of grille 2 based on the target adjustment parameters and the distance between the user and the indoor unit.

[0040] Here, the target adjustment parameters include, but are not limited to, the air conditioner's equipment parameters, user-set parameters, and detected environmental parameters. The air conditioner's inherent equipment parameters include, but are not limited to, its horsepower, installation height, air outlet width (11), and grille size (2). User-set parameters include, but are not limited to, set temperature, set operating mode, and fan speed. Detected environmental parameters include, but are not limited to, indoor ambient temperature, indoor ambient humidity, and indoor area. Based on the distance between the user and the indoor unit, the target adjustment parameters are further considered to comprehensively measure and determine the target position of grille (2), achieving precise and idealized airflow to the user under different operating modes.

[0041] In some embodiments, such as Figure 3 As shown, S22 determines the adjustment parameters according to the operating mode, and may further include S221 and S222.

[0042] S221: When the air conditioner is in gentle wind mode, determine the first adjustment parameter as the target adjustment parameter.

[0043] Here, "gentle breeze mode" means that the airflow blown out by the indoor unit in this mode is mainly turbulent and the user has a gentle breeze feeling.

[0044] S222: When the air conditioner is in direct blowing mode, determine the second adjustment parameter as the target adjustment parameter, wherein the second adjustment parameter is greater than or equal to the first adjustment parameter.

[0045] Here, "direct-blow mode" refers to a mode where the airflow from the indoor unit is primarily a direct jet, blowing directly onto the user. Since the second adjustment parameter in direct-blow mode may be greater than or equal to the first adjustment parameter in gentle-wind mode, the adjustment parameter is determined based on different modes, taking into account multiple factors to better determine the target position of grille 2. In some examples, the first and second adjustment parameters include one or more of the air conditioner's equipment parameters, user-set parameters, and detected environmental parameters.

[0046] In some embodiments, such as Figure 4 As shown, the first adjustment parameter is α; After determining the first adjustment parameter as the target adjustment parameter in S221, S23 determines the target position of the grille 2, including S231.

[0047] S231: Based on the target adjustment parameter ω and the distance H between the user and the indoor unit, calculate the target distance S between the grille 2 and the air outlet 11, S=ωH, α=[1 / 300, 1 / 100].

[0048] Further calculations are performed in gentle breeze mode to obtain the target distance. Here, ω = α, where α takes a value greater than or equal to 1 / 300 and less than or equal to 1 / 100. α represents the inherent parameter of different types of air conditioners. The value of α is fixed for the same type of air conditioner. The control modules for different types of air conditioners all use the above formula to calculate the target distance. Only the α value of the current model air conditioner needs to be input in advance, and the current control method can be adapted to different types of air conditioners.

[0049] like Figure 3 As shown, when the air conditioner is in direct-blowing mode, S222 determines the second adjustment parameter as the target adjustment parameter, further including: S2221: Determine that the distance between the user and the indoor unit is within the first distance range, and determine the second adjustment parameter as β; S2222: Determine that the distance between the user and the indoor unit is within the second distance interval, and determine the second adjustment parameter as 2β, wherein the minimum value of the second distance interval is greater than the maximum value of the first distance interval.

[0050] In direct-blow mode, the system first determines whether the distance between the user and the indoor unit falls within a first or second distance range, and then determines the target adjustment parameters. Since the movement range of grille 2 is limited, further determining the target adjustment parameters based on the distance between the user and the indoor unit allows for a more reasonable adjustment of grille 2 to the target position in accordance with the actual scenario.

[0051] After S222 determines the second adjustment parameter as the target adjustment parameter, S23 determines the target position of the grille 2, which includes S232: S232: Based on the target adjustment parameter ω and the distance H between the user and the indoor unit, calculate the target distance S between the grille 2 and the air outlet 11, S=ωH, β=[1 / 300, 1 / 100].

[0052] Here, β takes values ​​within the range of 1 / 300 to 1 / 100, representing an inherent parameter for different types of air conditioners. The value of β is fixed for the same type of air conditioner. Control modules for different types of air conditioners all calculate the target distance using the above formula. Only the β value of the current model air conditioner needs to be input in advance, and the current control method can adapt to different types of air conditioners.

[0053] When the distance between the user and the indoor unit is within the first distance range, ω = β. When the distance between the user and the indoor unit is within the first distance range, ω = 2β. It is easy to see that when the distance between the user and the indoor unit is in a larger second distance range, compared to when it is in a smaller first distance range, the grille 2 needs to move to a farther target position to meet the long-distance air supply requirement. When the distance between the user and the indoor unit is in a smaller first distance range, the grille 2 can meet the user's air supply requirement with a small change in position.

[0054] In some embodiments, such as Figure 6 As shown, the indoor unit also includes an air guide assembly, which is movably mounted on the grille 2 and can movably adjust the air outlet direction.

[0055] It should be noted that the air guide assembly can be installed on the inner or outer side of the grille 2, and the air guide assembly can be rotated or slidably mounted on the grille 2. No restrictions are placed on the structure of the air guide assembly; any structure capable of air guidance in related technologies is acceptable.

[0056] like Figure 5 As shown, after the S3 controls the grille 2 to move to the target position, the air conditioner control method also includes S4, which further includes S41 and S42.

[0057] S41: When the air conditioner is in gentle breeze mode, when the distance between the user and the indoor unit is within the first distance range, control the air guide component to move to the first gentle breeze posture; When the distance between the user and the indoor unit is within the second distance range, the air guide component is controlled to move to the second soft wind posture; wherein, the minimum value of the second distance range is greater than the maximum value of the first distance range, and the air volume of the grille 2 in the second soft wind posture is greater than the air volume in the first soft wind posture.

[0058] Based on the gentle breeze mode and the distance range between the user and the indoor unit, the air guide component is controlled to move to different gentle breeze postures, achieving different gentle breeze delivery purposes in combination with the distance between the user and the indoor unit. When the distance between the user and the indoor unit is in the second distance range, the user is farther away from the indoor unit, so the air guide component is moved to the second gentle breeze posture to increase the air volume of the grille 2, achieving gentle breeze delivery over long distances.

[0059] In some examples, the first distance interval is greater than or equal to 0 meters and less than or equal to 5 meters. The second distance interval is greater than 5 meters and less than or equal to 10 meters. The above ranges basically cover the application scenarios of the air conditioner in this application.

[0060] When the air conditioner is in direct-blowing mode, after the control grille 2 moves to the target position, the following is also included: S42: When the distance between the user and the indoor unit is within the first distance range, control the air guide assembly to move to the first direct blowing posture so that the air conditioner can blow air out from the area between the side wall of the grille 2 and the air outlet 11.

[0061] Here, the periphery of the grille 2 is spaced apart from the sidewall of the air outlet 11 to allow airflow to pass through. At this time, the weak airflow blown out by the grille 2 is attracted to the strong airflow blown out by the periphery of the grille 2, forming a wind field that is weak in the middle and strong on both sides, creating an embracing wind surrounding the user.

[0062] When the distance between the user and the indoor unit is within the second distance range, the air guide component is controlled to move to the second direct blowing posture; wherein, the air outlet area of ​​the grille 2 in the first direct blowing posture is smaller than the air outlet area of ​​the grille 2 in the second direct blowing posture.

[0063] Based on the direct-blowing mode and the distance range between the user and the indoor unit, the air guide component is controlled to move to different direct-blowing postures, achieving different direct-flow air delivery purposes depending on the distance between the user and the indoor unit. When the distance between the user and the indoor unit is in the second distance range, the distance between the user and the indoor unit is relatively small. By moving the air guide component to the second direct-blowing posture, the air outlet area of ​​the grille 2 is increased, thereby balancing the airflow blown from the grille 2 and between the periphery of the grille 2 and the side wall of the air outlet 11, achieving full-area air delivery and long-distance air supply.

[0064] In some examples, the indoor unit is a floor-standing air conditioner indoor unit, with the grille 2 spaced apart from the side wall of the air outlet 11 along both sides in the horizontal direction to allow airflow to pass through.

[0065] In some examples, the first distance interval is greater than or equal to 0 meters and less than or equal to 5 meters. The second distance interval is greater than 5 meters and less than or equal to 10 meters. The above ranges basically cover the application scenarios of the air conditioner in this application.

[0066] In some embodiments, such as Figure 6 As shown, the air guiding assembly includes multiple air guiding components, which include a first air guiding component 3, a second air guiding component 4, a third air guiding component 5, and a fourth air guiding component 6 arranged sequentially. The multiple air guiding components are independently and movably installed on the inner side of the grille 2, and each air guiding component is provided with multiple soft air holes. The main body 1 is provided with an inner air duct 12, and the air outlet 11 has a first side wall 111 and a second side wall 112 arranged opposite to each other along the width direction of the air outlet 11.

[0067] It should be noted that the inner air duct 12 is connected to the air outlet 11, and the first side wall 111 and the second side wall 112 extend smoothly to the side wall of the inner air duct 12. The width direction of the air outlet 11 refers to the horizontal direction.

[0068] like Figure 6 As shown, in S41, controlling the air guide assembly to move to the first gentle breeze posture specifically includes: The airflow channel formed between the first air guide 3 and the second air guide 4 and the shielding grille 2 and the first side wall 111 is controlled, and the remaining air guides shield the grille 2.

[0069] Here, the first air guide 3 may include one or more first air guide plates, and the second air guide 4 may include one or more second air guide plates. The first air guide 3 and the second air guide 4 reduce the amount of air flowing out from between the grille 2 and the first side wall 111 by blocking the airflow channel. The third air guide 5 and the fourth air guide 6 achieve gentle airflow from the grille 2 by blocking the grille 2, thus achieving a wide-area gentle airflow from the indoor unit.

[0070] In some examples, the indoor unit includes a cross-flow fan 7, with the second sidewall 112 facing the cross-flow fan 7. Due to the airflow characteristics of the cross-flow fan 7, the airflow is concentrated and flows out along the extension direction of the first sidewall 111, while the airflow near the second sidewall 112 is smaller. By blocking the airflow channel between the first air guide 3 and the second air guide 4 and the grille 2 and the first sidewall 111, the airflow on the left and right sides is balanced, achieving uniform air delivery.

[0071] like Figure 7 As shown, in S41, controlling the air guide assembly to move to the second gentle breeze posture specifically includes: The first air guide 3 and the first side wall 111 are controlled to abut against each other to block the airflow channel formed between the grille 2 and the first side wall 111. The second air guide 4 abuts against the middle of the first air guide 3 to block the area of ​​the first air guide 3 near the grille 2. The remaining air guides block the grille 2.

[0072] Because the second air guide 4 is equipped with a soft air hole, by abutting the second air guide 4 against the middle of the first air guide 3, part of the airflow is diverted through the second air guide 4 and flows out from the grille 2, increasing the air volume of the grille 2, and realizing long-distance soft air delivery when the user is far away from the indoor unit in soft air mode.

[0073] In some examples, the first air guide 3 includes a first air guide plate, the second air guide 4 includes a second air guide plate, the third air guide 5 includes two third air guide plates and a connecting rod connecting the third air guide plates, and the fourth air guide 6 includes a fourth air guide plate. The width of the second air guide plate is greater than the width of the first air guide plate. The width of the third air guide plate located near the second air guide plate is greater than the width of the other third air guide plate. The width of the third air guide plate located near the fourth air guide plate is greater than the width of the fourth air guide plate.

[0074] like Figure 8 As shown, in S42, controlling the air guide assembly to move to the first direct-blowing posture specifically includes: The free ends of the second air guide 4 and the third air guide 5 are brought closer to each other to evenly distribute the airflow from the inner air duct 12.

[0075] The first air guide 3 is controlled to abut against the middle area of ​​the second air guide 4 to form a first side air outlet channel between the areas of the first air guide 3 and the second air guide 4 away from the grille 2 and the first side wall 111.

[0076] The fourth air guide 6 is controlled to abut against the middle region of the third air guide 5 to form a second side air outlet channel between the fourth air guide 6, the region of the third air guide 5 away from the grille 2, and the second side wall 112.

[0077] The first side air outlet duct and the inner air duct 12 are smoothly connected, the second side air outlet duct and the inner air duct 12 are connected by a bend, and the distance between the second air guide 4 and the first side wall 111 is less than the distance between the fourth air guide 6 and the second side wall 112.

[0078] Here, based on the airflow characteristics of the cross-flow fan 7, the distance from the free end of the second air guide 4 to the first side wall 111 is less than the distance from the free end of the third air guide 5 to the second side wall 112, in order to balance the airflow distribution on both sides. The airflow is concentrated and discharged from the left and right sides through the first side air outlet channel and the second side air outlet channel, thereby forming an enveloping airflow.

[0080] Here, increasing the air outlet angle means making the air outlet range larger than that in the first direct-blowing posture. In the second direct-blowing posture, the area of ​​the air guide component blocking the grille 2 is reduced, increasing the air outlet range of the grille 2 to achieve air outlet across the entire area as much as possible.

[0082] The flow rates on the left and right sides are balanced by making the first flow port smaller than the second flow port. In some examples, in the first straight-blow orientation, the distance between the second air guide 4 and the first sidewall 111 is A1, and the distance between the third air guide 5 and the second sidewall 112 is A2, where A1:A2 = 1.1~5.
