[0042] In order to enable persons skilled in the art to more fully understand the features and technical contents of the embodiments of the present disclosure, the implementation of the embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings, which are only used for reference and do not limit the embodiments of the present disclosure. In the following technical description, in order to facilitate explanation, a plurality of details are provided to provide a full understanding of the disclosed embodiments. However, one or more embodiments can still be implemented without these details. In other cases, in order to simplify the drawings, well-known structures and devices can be simplified.

[0043] In combination with Figure 1 and Figure 2 shown, the air conditioner indoor unit 100 provided by the embodiments of the present disclosure includes a first motor, a second motor, an air deflector 103, and a connecting rod 104, the air deflector 103 is rotationally connected with the connecting rod 104, a first output shaft 101 of the first motor is connected with the connecting rod 104, and a second output shaft 102 of the second motor is connected with the air deflector 103.

[0044] In combination with Figure 2As shown, the rotational movement of the guide vane is fitted as a light rod circular motion in a vertical plane. Since the guide vane rotational movement motor provides torque T, and T = FR, F is the tangential force of the circular motion, and R is the rotational radius. Among them, the center of the circular motion is the axis of the first output shaft, and the rotational radius is the distance from the axis of the first output shaft to the center of gravity of the guide vane. Assuming that R is constant, only the change of the tangential force needs to be analyzed, and the change of the torque caused by the tangential force can be obtained. During the movement of the guide vane, the force on the center of gravity of the guide vane when the center of gravity of the guide vane is at the lowest point and on the lower half of the circular motion is analyzed, and the change of the tangential force of the guide vane in the circular motion is observed.

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

[0046] As shown in Figure 3 , when the center of gravity of the guide vane is at the lowest point of the circle, i.e. point A, the direction of the gravitational force is perpendicular to the direction of the tangential force of the circular motion, so there is no component force of the gravitational force in the tangential direction of the circular motion, and the component force F of the guide vane in the tangential direction of the circular motion is 0.

[0047] As shown in Figure 4 , when the center of gravity of the guide vane is on the lower half of the circle, i.e. point B, it can be seen from the figure that the line connecting the center of gravity and the rotational center has an angle with the horizontal direction, and the angle is θ, so the component force F of the gravitational force in the tangential direction of the circular motion is mg*cosθ. Among them, mg is the gravitational force. The tangential force for making the guide vane circular motion should be equal to the component value of the gravitational force mg in the tangential direction of the circular motion. The gravitational force mg is fixed, so when θ is smaller, cosθ is larger, and the tangential force is larger.

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

[0049] In summary, assuming that the rotational radius is constant, the tangential force required by the guide vane during the upward rotation of the guide vane increases more and more when the center of gravity of the guide vane rotates to the horizontal position, and the required torque also increases more and more. From the horizontal position to the closed state position, the required tangential force becomes smaller and smaller, and the required torque becomes smaller and smaller.

[0050] Further, the radius of rotation is analyzed. The air deflector can rotate around the axis of the second output shaft while rotating around the axis of the first output shaft, so that the distance of the gravity center of the air deflector from the axis of the first output shaft changes. That is, the size of the radius of rotation changes. When the gravity center of the air deflector is on the same straight line as the axis of the first output shaft and the axis of the second output shaft, the radius of rotation from the axis of the first output shaft is the largest at this time. Assuming that the tangential force of the circular motion is constant, only considering the radius of rotation, the largest torque required for the rotation of the gravity center of the air deflector around the axis of the first output shaft is at this position.

[0051] In combination Figure 6 As shown in the figure, the circle at the axis of the second output shaft can be seen. Before this position, the gravity center of the air deflector is farther and farther away from the axis of the first output shaft, the radius of rotation is larger and larger, and the required torque is larger and larger. After this position, the gravity center of the air deflector is closer and closer to the axis of the first output shaft, the radius of rotation is smaller and smaller, and the required torque is smaller and smaller.

[0052] In combination with the force analysis and the radius of rotation analysis during the rotation of the air deflector, it can be concluded that, in the process of the rotation of the gravity center of the air deflector around the axis of the first output shaft, the largest torque position is the horizontal position of the gravity center of the air deflector on the circle around the axis of the first output shaft in the force analysis. In the radius of rotation, the largest torque position is that the gravity center 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] Further, it is determined that, in the process of the rotation of the air deflector, the largest torque required position is that the gravity center of the air deflector, the axis of the first output shaft and the axis of the second output shaft are on a straight line, and this situation occurs when the gravity center of the air deflector is at the horizontal position of the circular motion.

[0054] In the process of the rotation of the air deflector, when passing through this position, the output torque required by the first motor is the largest, which can cause the air deflector to shake and the motor to be in high load. In order to avoid passing through the largest torque required position in the process of the rotation of the air deflector, the first motor and the second motor need to have a rotation relationship in the case of avoiding this position, and the rotation angle needs to be calculated to avoid the maximum of the radius of rotation and the force at the same time.

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

[0056] In combination Figure 7As shown, the embodiment of the present disclosure provides a control method for an air conditioner indoor unit, the air conditioner indoor unit comprising a first motor, a second motor, a guide vane and a connecting rod, the guide vane being rotationally connected with the connecting rod, a first output shaft of the first motor being connected with the connecting rod, a second output shaft of the second motor being connected with the guide vane, the control method comprising:

[0057] S701, the processor acquires a current position relationship between the center of gravity of the guide vane, the axis of the first output shaft and the axis of the second output shaft in response to a guide vane starting request.

[0058] S702, the processor determines operation parameters of the first motor and the second motor according to the starting request and the current position relationship.

[0059] S703, the processor controls the first motor and the second motor to operate according to the operation parameters.

[0060] In this embodiment, the guide vane is confirmed to need to be rotated in response to a guide vane starting request. Then the current position relationship between the center of gravity of the guide vane, the axis of the first output shaft and the axis of the second output shaft is acquired. Whether the order of rotation of the first motor and the second motor needs to be controlled when the guide vane is rotated to avoid the position of the maximum required torque is confirmed according to the starting request and the current position relationship. Then the operation parameters of the first motor and the second motor are confirmed.

[0061] Further, the first motor and the second motor are controlled to operate according to the operation parameters of the first motor and the second motor, so as to avoid the position of the maximum required torque, reduce the maximum output torque required by the motor, and then reduce the degree of guide vane shaking and the load of the motor.

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

[0063] S801, the processor acquires a current position relationship between the center of gravity of the guide vane, the axis of the first output shaft and the axis of the second output shaft in response to a guide vane starting request.

[0064] S802, the processor acquires a target position relationship between the center of gravity of the guide vane, the axis of the first output shaft and the axis of the second output shaft according to the starting request.

[0065] S803, the processor determines operation parameters of the first motor and the second motor according to the target position relationship, the current position relationship and the starting request.

[0066] S804, the processor controls the first motor and the second motor to operate according to the operation parameters.

[0067] In this embodiment, by starting the request, the target position relationship between the center of gravity of the deflector, the axis of the first output shaft and the axis of the second output shaft is obtained, the target position of the deflector rotation is confirmed, so as to confirm whether the deflector will pass through the required torque maximum position in the rotation process. Further, according to the target position relationship, the current position relationship and the starting request, the operation parameters of the first motor and the second motor are determined. In the case that the deflector will pass through the required torque maximum position in the rotation process, the required torque maximum position is avoided by controlling the rotation of the first motor and the second motor, and the deflector shaking degree is reduced, and the motor load is reduced.

[0068] In combination Figure 9 As shown in the figure, the embodiment of the present disclosure provides another control method for an air conditioner indoor unit, comprising:

[0069] S901, the processor obtains the current position relationship between the center of gravity of the deflector, the axis of the first output shaft and the axis of the second output shaft in response to the deflector starting request.

[0070] S902, the processor obtains the target position relationship between the center of gravity of the deflector, the axis of the first output shaft and the axis of the second output shaft according to the starting request.

[0071] S903, the processor marks the coordinates of the center of gravity of the deflector, the axis of the first output shaft and the axis of the second output shaft in the preset XY rectangular coordinate system.

[0072] S904, the processor determines the first rotation angle θ1 and the second rotation angle θ2 in the operation parameters of the second motor according to the target position relationship and the starting request in the case that the current position relationship satisfies the first position relationship in the XY rectangular coordinate system.

[0073] S905, the processor determines the operation parameters of the first motor according to the starting request.

[0074] S906, the processor controls the first motor and the second motor to operate according to the operation parameters.

[0075] In this embodiment, by marking the coordinates of the center of gravity of the deflector, the axis of the first output shaft and the axis of the second output shaft in the preset XY rectangular coordinate system, the current position relationship between the center of gravity of the deflector, the axis of the first output shaft and the axis of the second output shaft is confirmed. In the case that the current position relationship is the first position relationship, it is confirmed that the deflector will pass through the required torque maximum position in the rotation process.

[0076] Therefore, the first rotation angle θ1 and the second rotation angle θ2 are calculated according to the relationship between the coordinates of the gravity center of the deflector and the target position. After the second motor is rotated by the first rotation angle, the relationship between the gravity center of the 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 maximum at this time. During the process of rotating the second motor by the second rotation angle, the rotation radius gradually decreases and the stress gradually increases, so as to avoid the position with the maximum required torque.

[0077] Specifically, the first rotation angle is in the range of 0° to 32°. The specific value of the first rotation angle includes 0°, 20° and 32°.

[0078] Specifically, the first total rotation angle is in the range of 33° to 102°. The specific value of the first rotation angle includes 33°, 90° and 102°.

[0079] Optionally, when the relationship between the gravity center of the deflector, the axis of the first output shaft and the axis of the second output shaft is the first position relationship, the gravity center of the deflector is located below the extension line of the line connecting the axis of the first output shaft and the axis of the second output shaft.

[0080] Optionally, when the relationship between the gravity center of the deflector, the axis of the first output shaft and the axis of the second output shaft is the second position relationship, the gravity center of the deflector is located on the extension line of the line connecting the axis of the first output shaft and the axis of the second output shaft.

[0081] Optionally, when the relationship between the gravity center of the deflector, the axis of the first output shaft and the axis of the second output shaft is the third position relationship, the gravity center of the deflector is located above the extension line of the line connecting the axis of the first output shaft and the axis of the second output shaft.

[0088] S1006, the processor calculates θ2 according to α and θ1.

[0089] S1007, the processor determines the operation parameter of the first motor according to the starting request.

[0090] S1008, the processor controls the first motor and the second motor to operate according to the operation parameter.

[0091] In this embodiment, θ1 is calculated according to the coordinate value of the gravity center of the deflector and the target position relationship, so that the gravity center of the deflector, the axis of the first output shaft and the axis of the second output shaft are in the second position relationship after the second motor rotates θ1, and the maximum rotation radius is achieved.

[0092] Further, α corresponding to the starting request is obtained, and θ2 is calculated according to α and θ1, so that the target position is reached after the second motor rotates θ2, and the rotation of the deflector is completed.

[0093] Optionally, in the case that 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, in the case that 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 the gravity center of the deflector, the axis of the first output shaft and the axis of the second output shaft are in the second position relationship after the second motor rotates the first rotation angle. Wherein, θ1 is calculated according to the coordinate value of the gravity center of the deflector.

[0095] Specifically, in combination with Figure 11 It is shown that the current gravity center of the deflector is D point, and the coordinates of D point are (x, y), then the relationship between θ1 and x, y is: Further, it is obtained that Then the first rotation angle θ1 of the second motor is obtained.

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

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

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

[0110] S1302, the processor determines the operation parameters of the first motor and the second motor according to the starting request and the current position relationship.

[0111] S1303, in the case that the starting request is a closing request and the current position relationship is the first position relationship, the processor controls the second motor to rotate to the second position relationship in the first direction first, and then controls the first motor and the second motor to rotate to the target position in the first direction simultaneously.

[0112] S1304, in the case that the starting request is a closing 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 to the target position in the first direction simultaneously.

[0113] S1305, in the case that the starting request is an opening request and the current position relationship is the third position relationship, the processor controls the second motor to rotate to the second position relationship in the second direction first, and then controls the first motor and the second motor to rotate to the target position in the second direction simultaneously.

[0114] S1306, in the case that the starting 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 to the target position in the second direction simultaneously.

[0115] In this embodiment, by determining the rotation sequence of the first motor and the second motor according to the starting request and the current position relationship, the position of the maximum required torque is avoided.

[0116] Specifically, in the case that the starting request is a closing request and the current position relationship is the first position relationship, the second motor is controlled to rotate by the first rotation angle first, so that the position relationship of the gravity center of the deflector, the axis of the first output shaft and the axis of the second output shaft is the second position relationship, and 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 simultaneously, so that the rotation radius gradually decreases and the force gradually increases in the rotation process after this position, the position of the maximum force and the maximum radius is avoided, and then the position of the maximum required torque is avoided.

[0117] In the case that the starting request is an opening request and the current position relationship is the third position relationship, the second motor is controlled to rotate to the second position relationship in the second direction first, so that the rotation radius at this time reaches the maximum. The line between the axis of the first output shaft and the axis of the second output shaft has an angle with the horizontal direction, and in the process of controlling the first motor and the second motor to rotate to the target position in the second direction simultaneously, the rotation radius gradually decreases, and the force first increases and then decreases, the position of the maximum force and the maximum radius is avoided, and then the position of the maximum required torque is avoided.

[0118] Specifically, the rotation angle of the first motor ranges from 0° to 68°. The rotation angle of the first motor specifically includes 0°, 30° and 68°.

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

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

[0121] Specifically, assuming that the first stepper motor has a pulse interval of a milliseconds and a step angle of the second stepper motor has a pulse interval of m milliseconds and a step angle of wherein the first stepper motor rotates b° and runs c steps, and the second stepper motor rotates n° and runs k steps.

[0122] The time required for the first stepper motor to run 1° is milliseconds, and the maximum running time of the first stepper motor is milliseconds. Wherein 68 is the maximum running 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 running angle of the second stepper motor when rotating the first rotation angle.

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

[0125] Optionally, as shown in Figure 11 before responding to the air deflector start request, further comprising: constructing an XY rectangular coordinate system in a plane perpendicular to the axis of the first output shaft. Wherein the origin of the coordinate system is the axis center of the second output shaft, the connection line between the axis center of the first output shaft and the axis center of the second output shaft is the X-axis, and the straight line passing through the axis center of the second output shaft and perpendicular to the X-axis is the Y-axis, and the Y-axis is positive in the upward direction in the height direction.

[0126] In this embodiment, by setting the XY rectangular coordinate system, the coordinates of 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 are determined, so as to calculate the first rotation angle and the second rotation angle of the second motor.

[0127] As shown in Figure 14 the present disclosure provides another control method for an air conditioner indoor unit, comprising:

[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 the origin, the connecting line of the axis center of the first output shaft and the axis center of the second output shaft is the X axis, and the straight line passing through the axis center of the second output shaft and perpendicular to the X axis is the Y axis, and the Y axis is positive in the upward direction in the height direction.

[0129] S1402, the processor obtains the longitudinal coordinate of the center of gravity of the deflector in the XY rectangular coordinate system in response to the deflector starting request.

[0130] S1403, the processor determines that the positional relationship between the center of gravity of the deflector, the axis center of the first output shaft and the axis center of the second output shaft is the first positional relationship when the longitudinal coordinate is less than zero.

[0131] S1404, the processor determines that the positional relationship between the center of gravity of the deflector, the axis center of the first output shaft and the axis center of the second output shaft is the second positional relationship when the longitudinal coordinate is equal to zero.

[0132] S1405, the processor determines that the positional relationship between the center of gravity of the deflector, the axis center of the first output shaft and the axis center of the second output shaft is the third positional relationship when the longitudinal coordinate is greater than zero.

[0133] S1406, the processor determines the operation parameters of the first motor and the second motor according to the starting request and the current positional relationship.

[0134] S1407, the processor controls the first motor and the second motor to operate according to the operation parameters.
