[0042] In order to be able to understand the features and technical contents of the embodiments of the present disclosure in more detail, the implementation of the embodiments of the present disclosure is described in detail below in conjunction with the accompanying drawings. The attached drawings are for reference only and are not used to limit the embodiments of the present disclosure. In the following technical description, for the convenience of explanation, a full understanding of the disclosed embodiments is provided through multiple details. However, one or more embodiments can still be implemented without these details. In other cases, to simplify the drawings, well-known structures and devices can be simplified for display.

[0043] Combination Figure 1 and Figure 2 As shown, the air-conditioning indoor unit 100 provided in the embodiment of the present disclosure includes a first motor, a second motor, an air guide plate 103 and a connecting rod 104, the air guide plate 103 is rotatably connected to the connecting rod 104, the first output shaft 101 of the first motor is connected to the connecting rod 104, and the second output shaft 102 of the second motor is connected to the air guide plate 103.

[0044] Combination Figure 2As shown, the rotational motion of the air deflector is fitted as the circular motion of a light rod on a vertical plane for study. Since the air deflector rotational motion motor provides torque T, and T=FR, F is the tangential force of the circular motion, and R is the rotation radius. Among them, the center of the circular motion is the axis of the first output shaft, and the rotation radius is the distance from the axis of the first output shaft to the center of gravity of the air deflector. Assuming that R is unchanged, it is only necessary to analyze the change of this tangential force, and it can be concluded that the torque is only affected by the tangential force. During the movement of the air deflector, the focus is on analyzing the force on the center of gravity of the air deflector when the center of gravity of the air deflector is at the lowest point of the circular motion and on the lower semicircle, and observing the change of the tangential force of the air deflector in the circular motion.

[0045] It should be noted that Figure 3 , Figure 4 and Figure 5 Taking the rotation of the first motor in the V1 direction as an example, when the first motor rotates in the opposite direction, the force analysis and the rotation radius analysis are the same as those in the V1 direction.

[0046] Combination Figure 3 As shown, when the center of gravity of the air guide plate is at the lowest point of the circle, that is, point A, the direction of gravity is perpendicular to the direction of the tangential force of the circular motion, so the gravity has no component in the tangential direction of the circular motion, and therefore the component force F of the air guide plate in the tangential direction of the circular motion is F=0.

[0047] Combination Figure 4 As shown in the figure, when the center of gravity of the wind deflector is on the lower half of the circle, that is, point B, it can be seen from the figure that the line connecting the gravity direction and the rotation center has an angle with the horizontal direction. Let the angle be θ, so the component force of gravity in the tangential direction of circular motion is F=mg*cosθ. Among them, mg is gravity. The tangential force that makes the wind deflector move in the circle should be equal to the component force value of gravity mg in the tangential direction of circular motion. Gravity mg is fixed, so when θ is smaller, cosθ is larger, and the tangential force is larger.

[0048] Combination Figure 5 As shown, when the line connecting the center of gravity of the air guide plate and the axis center of the first output shaft is in a horizontal position, that is, point C, θ is 0°, cosθ=1, so the tangential force should be equal to the gravity.

[0049] In summary, assuming that the rotation radius remains unchanged, when the air guide plate rotates upward, the tangential force required in the process of the center of gravity of the air guide plate rotating to the horizontal position becomes larger and larger, and the torque required becomes larger and larger. In the process of rotating from the horizontal position to the closed state, the tangential force required becomes smaller and smaller, and the torque required becomes smaller and smaller.

[0050] Furthermore, the rotation radius is analyzed. The air guide plate can rotate around the axis of the first output shaft and the axis of the second output shaft at the same time, so the distance of the center of gravity of the air guide plate relative to the axis of the first output shaft will change. That is, the size of the rotation radius will change. When the center of gravity of the air guide plate is on the same straight line as the axis of the first output shaft and the axis of the second output shaft, the rotation radius relative to the axis of the first output shaft is the largest. Assuming that the tangential force of the circular motion remains unchanged, only considering the rotation radius, this is the maximum torque position required for the center of gravity of the air guide plate to rotate around the axis of the first output shaft.

[0051] Combination Figure 6 As shown in the figure, the circle at the axis of the second output shaft shows that before this position, the center of gravity of the air deflector is farther and farther from the axis of the first output shaft, the rotation radius is larger and larger, and the required torque is larger and larger. After this position, the center of gravity of the air deflector is closer and closer to the axis of the first output shaft, the rotation radius is smaller and smaller, and the required torque is smaller and smaller.

[0052] Combined with the force analysis and the analysis of the rotation radius during the rotation of the air deflector, it can be concluded that when the center of gravity of the air deflector rotates around the axis of the first output shaft, in the force analysis, the maximum torque position is the horizontal position of the center of gravity of the air deflector on the circle around the axis of the first output shaft. In terms of the rotation radius, the maximum torque position is the position where the center of gravity of the air deflector, the axis of the first output shaft, and the axis of the second output shaft are on a straight line.

[0053] It is further determined that during the rotation of the air guide plate, the position of the maximum torque required is when the center of gravity of the air guide plate, the axis of the first output shaft and the axis of the second output shaft are in a straight line, and this occurs when the center of gravity of the air guide plate is in a horizontal position of the circular motion.

[0054] During the rotation of the air deflector, when passing this position, the output torque required by the first motor is the maximum, which will cause the air deflector to shake and the motor to be overloaded. In order to avoid the air deflector passing the position with the maximum torque output during rotation, if this position needs to be avoided, the first motor and the second motor are controlled to rotate in sequence, and the rotation angle needs to be calculated to avoid the rotation radius and the force reaching the maximum at the same time.

[0055] In some embodiments, in combination Figure 1 As shown, an air-conditioning indoor unit 100 is provided, comprising a processor 1500 and a memory 1501 storing program instructions, wherein the processor 1500 is configured to execute a control method for the air-conditioning indoor unit when running the program instructions.

[0056] Combination Figure 7As shown, an embodiment of the present disclosure provides a control method for an indoor unit of an air conditioner, wherein the indoor unit of the air conditioner comprises a first motor, a second motor, an air guide plate and a connecting rod, wherein the air guide plate is rotatably connected to the connecting rod, a first output shaft of the first motor is connected to the connecting rod, and a second output shaft of the second motor is connected to the air guide plate, and the control method comprises:

[0057] S701: In response to a request to start the air deflector, the processor obtains a current positional relationship between the center of gravity of the air deflector, the axis center of the first output shaft, and the axis center of the second output shaft.

[0058] S702: The processor determines operating parameters of the first motor and the second motor according to the start request and the current position relationship.

[0059] S703: The processor controls the operation of the first motor and the second motor according to the operation parameters.

[0060] In this embodiment, by responding to the air deflector start request, it is confirmed that the air deflector needs to be rotated. Then, the current position relationship between the center of gravity of the air deflector, the axis center of the first output shaft, and the axis center of the second output shaft is obtained. Through the start request and the current position relationship, it is confirmed whether it is necessary to control the rotation sequence of the first motor and the second motor when rotating the air deflector to avoid the required maximum torque position, and then the operating parameters of the first motor and the second motor are confirmed.

[0061] Furthermore, according to the operating parameters of the first motor and the second motor, the operation of the first motor and the second motor is controlled to avoid the required maximum torque position, reduce the maximum output torque required by the motor, thereby reducing the degree of vibration of the air guide plate and reducing the motor load.

[0062] Combination Figure 8 As shown, the embodiment of the present disclosure provides another control method for an air conditioner indoor unit, comprising:

[0063] S801: In response to a request to start the air deflector, the processor obtains a current positional relationship between the center of gravity of the air deflector, the axis center of the first output shaft, and the axis center of the second output shaft.

[0064] S802: The processor obtains a target position relationship between the center of gravity of the air guide plate, the axis center of the first output shaft, and the axis center of the second output shaft according to the startup request.

[0065] S803: The processor determines operating parameters of the first motor and the second motor according to the target position relationship, the current position relationship and the start request.

[0066] S804: The processor controls the operation of the first motor and the second motor according to the operation parameters.

[0067] In this embodiment, the target position relationship between the center of gravity of the air deflector, the axis of the first output shaft, and the axis of the second output shaft is obtained through a start request, so as to confirm the target position of the air deflector rotation, so as to confirm whether the air deflector will pass through the required maximum torque position during the rotation process. Then, the operating parameters of the first motor and the second motor are determined according to the target position relationship, the current position relationship, and the start request. In this way, when the air deflector passes through the required maximum torque position during the rotation process, the rotation of the first motor and the second motor is controlled to avoid the required maximum torque position, thereby reducing the vibration of the air deflector and reducing the motor load.

[0068] Combination Fig. 9 As shown, the embodiment of the present disclosure provides another control method for an air conditioner indoor unit, comprising:

[0069] S901: In response to a request to start the air deflector, the processor obtains a current positional relationship between the center of gravity of the air deflector, the axis center of the first output shaft, and the axis center of the second output shaft.

[0070] S902: The processor obtains a target position relationship between the center of gravity of the air guide plate, the axis center of the first output shaft, and the axis center of the second output shaft according to the startup request.

[0071] S903: The processor marks the coordinates of the center of gravity of the air guide plate, the axis center of the first output shaft, and the axis center of the second output shaft in a preset XY rectangular coordinate system.

[0072] S904: The processor determines, in an XY rectangular coordinate system, a first rotation angle θ1 and a second rotation angle θ2 in operating parameters of the second motor according to a target position relationship and a start request when the current position relationship satisfies a first position relationship.

[0073] S905: The processor determines operating parameters of the first motor according to the start request.

[0074] S906: The processor controls the operation of the first motor and the second motor according to the operation parameters.

[0075] In this embodiment, the center of gravity of the air deflector, the axis of the first output shaft, and the axis of the second output shaft are marked in a preset XY rectangular coordinate system to facilitate confirmation of the current positional relationship between the center of gravity of the air deflector, the axis of the first output shaft, and the axis of the second output shaft. When the current positional relationship is the first positional relationship, it is confirmed that the air deflector will pass through the required maximum torque position during the rotation process.

[0076] Therefore, the first rotation angle θ1 and the second rotation angle θ2 are calculated by the coordinates of the center of gravity of the air deflector and the target position relationship. After the second motor is rotated by the first rotation angle, the relationship between the center of gravity of the air deflector, the axis of the first output shaft, and the axis of the second output shaft is the first position relationship or the second position relationship, so that the rotation radius is the largest at this time. In the process of rotating the second motor by the second rotation angle, the rotation radius gradually decreases, and the force gradually increases to avoid the required maximum torque position.

[0077] Specifically, the value range of the first rotation angle includes 0° to 32°. Specific values ​​of the first rotation angle include: 0°, 20° and 32°.

[0078] Specifically, the value range of the first total rotation angle includes 33° to 102°. Specific values ​​of the first rotation angle include: 33°, 90° and 102°.

[0079] Optionally, when the center of gravity of the air guide plate, the axis center of the first output shaft and the axis center of the second output shaft are in a first positional relationship, the center of gravity of the air guide plate is located below the extension line of the line connecting the axis center of the first output shaft and the axis center of the second output shaft.

[0080] Optionally, when the center of gravity of the air guide plate, the axis center of the first output shaft and the axis center of the second output shaft are in a second positional relationship, the center of gravity of the air guide plate is located on an extension line of a line connecting the axis center of the first output shaft and the axis center of the second output shaft.

[0081] Optionally, when the center of gravity of the air guide plate, the axis center of the first output shaft and the axis center of the second output shaft are in a third position relationship, the center of gravity of the air guide plate is located above the extension line of the line connecting the axis center of the first output shaft and the axis center of the second output shaft.

[0082] Combination Fig.10 As shown, the embodiment of the present disclosure provides another control method for an air conditioner indoor unit, comprising:

[0083] S1001: In response to a request to start the air deflector, the processor obtains a current positional relationship between the center of gravity of the air deflector, the axis center of the first output shaft, and the axis center of the second output shaft.

[0084] S1002: The processor obtains a target position relationship between the center of gravity of the air guide plate, the axis center of the first output shaft, and the axis center of the second output shaft according to the startup request.

[0085] S1003: The processor marks the coordinates of the center of gravity of the air guide plate, the axis center of the first output shaft, and the axis center of the second output shaft in a preset XY rectangular coordinate system.

[0086] S1004: The processor calculates θ1 according to the coordinate value of the center of gravity of the air guide plate and the target position relationship in the XY rectangular coordinate system when the current position relationship satisfies the first position relationship.

[0087] S1005: The processor obtains a first total rotation angle α of the second motor according to the start request.

[0088] S1006: The processor calculates θ2 based on α and θ1.

[0089] S1007: The processor determines operating parameters of the first motor according to the start request.

[0090] S1008: The processor controls the operation of the first motor and the second motor according to the operating parameters.

[0091] In this embodiment, θ1 is calculated through the coordinate value of the center of gravity of the air guide plate and the target position relationship. After the second motor rotates θ1, the center of gravity of the air guide plate, the axis center of the first output shaft and the axis center of the second output shaft are in a second position relationship, thereby achieving the maximum rotation radius.

[0092] Furthermore, α corresponding to the start request is obtained, and θ2 is calculated through α and θ1, so that the second motor is rotated by θ2 to reach the target position and complete the rotation of the air guide plate.

[0093] Optionally, when the current position relationship is the first position relationship, and the target position relationship is the first position relationship or the second position relationship, the first rotation angle is θ1, and θ1 is equal to 0.

[0094] Optionally, when the current position relationship is the first position relationship and the target position relationship is the third position relationship, the first rotation angle is θ1, and after the second motor rotates the first rotation angle, the center of gravity of the air guide plate, the axis of the first output shaft, and the axis of the second output shaft are in a second position relationship. θ1 is calculated based on the coordinate value of the center of gravity of the air guide plate.

[0095] Specifically, combined Fig.11 Assume that the center of gravity of the wind deflector is currently point D, and the coordinates of point D are (x, y), then the relationship between θ1 and x, y is: It is concluded that Then the first rotation angle θ1 of the second motor is calculated.

[0096] Assuming that the first total rotation angle α of the second motor corresponding to the start request is 90°, the second rotation angle θ2 of the second motor is θ1=90°-θ1. Then the first rotation angle θ2 of the second motor is obtained.

[0097] Optionally, the first rotation angle is an angle required for the second motor to rotate from a current position to a second position relationship.

[0098] Optionally, the second rotation angle is an angle required for the second motor to rotate from the second position relationship to the target position.

[0099] Combination Fig.12 As shown, the embodiment of the present disclosure provides another control method for an air conditioner indoor unit, comprising:

[0100] S1201, the processor obtains the current position relationship between the center of gravity of the air deflector, the axis center of the first output shaft, and the axis center of the second output shaft in response to the air deflector start request.

[0101] S1202: The processor marks the coordinates of the center of gravity of the air guide plate, the axis center of the first output shaft, and the axis center of the second output shaft in a preset XY rectangular coordinate system.

[0102] S1203: In an XY rectangular coordinate system, when the current position relationship is in the second position relationship or the third position relationship, the processor determines a second total rotation angle μ in the operating parameters of the second motor according to the start request.

[0103] S1204: The processor determines operating parameters of the first motor according to the start request.

[0104] S1205: The processor controls the operation of the first motor and the second motor according to the operating parameters.

[0105] In this embodiment, when the current position relationship is in the second position relationship or the third position relationship, the wind deflector will not pass through the required maximum torque position during rotation, and the second total rotation angle μ of the second motor can be directly determined according to the start request, so that the second motor is rotated by μ to reach the target position and complete the rotation of the wind deflector.

[0109] S1301: In response to a request to start the air deflector, the processor obtains a current positional relationship between the center of gravity of the air deflector, the axis center of the first output shaft, and the axis center of the second output shaft.

[0110] S1302: The processor determines operating parameters of the first motor and the second motor according to the start request and the current position relationship.

[0111] S1303, when the startup request is a shutdown request and the current position relationship is the first position relationship, the processor first controls the second motor to rotate along the first direction to the second position relationship, and then controls the first motor and the second motor to rotate simultaneously along the first direction to the target position.

[0112] S1304: When the start request is a shutdown request and the current position relationship is the second position relationship or the third position relationship, the processor controls the first motor and the second motor to rotate simultaneously in the first direction to the target position.

[0113] S1305, when the startup request is an opening request and the current position relationship is the third position relationship, the processor first controls the second motor to rotate along the second direction to the second position relationship, and then controls the first motor and the second motor to rotate simultaneously along the second direction to the target position.

[0114] S1306: When the start request is an opening request and the current position relationship is the second position relationship or the first position relationship, the processor controls the first motor and the second motor to rotate simultaneously in the second direction to the target position.

[0115] In this embodiment, by setting the rotation sequence of the first motor and the second motor according to the relationship between the start request and the current position, when it is necessary to avoid the position with the maximum required torque, the position with the maximum required torque can be avoided.

[0116] Specifically, when the start request is a shutdown request and the current position relationship is the first position relationship, the second motor is controlled to rotate the first rotation angle first, so that the position relationship between the center of gravity of the air guide plate, the axis of the first output shaft and the axis of the second output shaft is the second position relationship, so that the rotation radius at this time reaches the maximum. Then the first motor and the second motor are controlled to rotate to the target position at the same time, so that after this position, the rotation radius gradually decreases, and the force gradually increases, avoiding the position where the force and radius are both the largest, and then avoiding the position where the required torque is the largest.

[0117] When the start request is an on request and the current position relationship is the third position relationship, the second motor is first controlled to rotate along the second direction to the second position relationship so that the rotation radius at this time reaches the maximum. The line between the axis of the current first output shaft and the axis of the second output shaft has an angle with the horizontal direction. In the process of controlling the first motor and the second motor to rotate to the target position simultaneously along the second direction, the rotation radius gradually decreases, and the force increases first and then decreases, avoiding the position where the force and radius are simultaneously the largest, and thus avoiding the position where the required torque is the largest.

[0118] Specifically, the rotation angle of the first motor has a value range of 0° to 68°. Specific values ​​of the rotation angle of the first motor include 0°, 30° and 68°.

[0119] Optionally, the first motor comprises a first stepper motor.

[0120] Optionally, the second motor comprises a second stepper motor.

[0121] Specifically, assume that the first stepper motor pulse interval is selected to be a milliseconds and the step angle is The pulse interval of the second stepper motor is m milliseconds and the step angle is When the first stepper motor rotates b°, it runs c steps, and when the second stepper motor rotates n°, it runs k steps.

[0122] Then the time required for the first stepper motor to run 1° is milliseconds, the maximum running time of the first stepper motor is Milliseconds. Among them, 68 is the maximum operating angle of the first stepper motor.

[0123] The time required for the second stepper motor to run 1° is The maximum time required for the second stepper motor to rotate the first rotation angle alone is Milliseconds. Wherein, 32 is the maximum operating angle when the second stepper motor rotates the first rotation angle.

[0124] The total running time t ranges from 0 to The total running time is the time required for the air guide plate to rotate from the current position to the target position.

[0125] Optionally, combined Fig.11 As shown, before responding to the air deflector start request, it also includes: constructing an XY rectangular coordinate system on a plane perpendicular to the axis of the first output shaft, wherein the axis of the second output shaft is taken as the origin, the line connecting the axis of the first output shaft and the axis of the second output shaft is taken as the X axis, the straight line passing through the axis of the second output shaft and perpendicular to the X axis is taken as the Y axis, and the Y axis has the upward direction in the height direction as the positive direction.

[0126] In this embodiment, an XY rectangular coordinate system is set to determine the coordinates of the center of gravity of the air guide plate, the axis center of the first output shaft, and the axis center of the second output shaft, so as to calculate the first rotation angle and the second rotation angle of the second motor.

[0128] S1401, the processor constructs an XY rectangular coordinate system on a plane perpendicular to the axis of the first output shaft, wherein the axis center of the second output shaft is taken as the origin, the line connecting the axis center of the first output shaft and the axis center of the second output shaft is taken as the X axis, the straight line passing through the axis center of the second output shaft and perpendicular to the X axis is taken as the Y axis, and the positive direction of the Y axis is upward in the height direction.

[0129] S1402: The processor obtains the vertical coordinate of the center of gravity of the air deflector in the XY rectangular coordinate system in response to the air deflector start request.

[0130] S1403, when the vertical coordinate is less than zero, the processor determines that the positional relationship among the center of gravity of the air guide plate, the axis center of the first output shaft, and the axis center of the second output shaft is a first positional relationship.

[0131] S1404: When the vertical coordinate is zero, the processor determines that the positional relationship among the center of gravity of the air guide plate, the axis center of the first output shaft, and the axis center of the second output shaft is a second positional relationship.

[0132] S1405: When the vertical coordinate is greater than zero, the processor determines that the positional relationship among the center of gravity of the air guide plate, the axis center of the first output shaft, and the axis center of the second output shaft is a third positional relationship.

[0134] S1407: The processor controls the operation of the first motor and the second motor according to the operation parameters.

[0135] In this embodiment, combined Fig.11 As shown, by judging the positive and negative values ​​of the center of gravity coordinates of the air guide plate, the positional relationship between the center of gravity of the air guide plate, the axis center of the first output shaft and the axis center of the second output shaft can be determined.
