Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, and more particularly to a control method for an air conditioner, an air conditioner, and a computer-readable storage medium. Background Technology

[0002] Since single-flow cabinet air conditioners cannot adjust the airflow direction, their anti-direct-blow function is generally achieved by adjusting the upward swing of the horizontal air guide plate assembly and / or reducing the fan speed. In actual use, it has been found that adjusting the upward swing of the horizontal air guide plate assembly is less effective at preventing direct blows, and combining this with reducing the fan speed results in a decrease in the air conditioner's output air volume, leading to insufficient air conditioning capacity.

[0003] It should be noted that the above content is only used to help understand the technical problem solved by the present invention, and does not represent an admission that the above content is prior art. Summary of the Invention

[0004] The main objective of this invention is to provide a control method for an air conditioner, an air conditioner, and a computer-readable storage medium, aiming to solve the technical problem of poor anti-direct-blowing effect in air conditioners.

[0005] To achieve the above objectives, the present invention provides a control method for an air conditioner. The air conditioner includes an air guide plate disposed at an air outlet and a vertical air guide strip assembly disposed within the air outlet. A linkage mechanism is provided between the air guide plate and the air guide strips of the vertical air guide strip assembly. The linkage mechanism is driven by a motor of the air conditioner. The control method for the air conditioner includes the following steps:

[0006] During the operation of the anti-direct-blowing mode, the target area where the user is located is determined;

[0007] The type of direct air protection is determined based on the target area, wherein the type of direct air protection includes at least one of right direct air protection, left direct air protection, front direct air protection, and full direct air protection;

[0008] According to the anti-direct-blow type, the motor drives the linkage mechanism to rotate the air guide plate and the vertical air guide strip assembly so that the air outlet outlet direction is directed towards an area other than the target area.

[0009] Optionally, the step of controlling the motor to drive the linkage mechanism to rotate the air guide plate and the vertical air guide strip assembly according to the anti-direct-blow type, so that the air outlet direction is directed towards an area other than the target area, includes:

[0010] According to the anti-direct-blow type, the motor drives the linkage mechanism to move the air guide plate to the target position corresponding to the target area, and drives the vertical air guide strip group to rotate to the target angle corresponding to the target area.

[0011] Optionally, the steps of controlling the motor to drive the linkage mechanism to move the air guide plate to the target position corresponding to the target area according to the anti-direct-blow type, and driving the vertical air guide strip group to rotate to the target angle corresponding to the target area include:

[0012] When the anti-direct-blow type is right-side anti-direct-blow, the motor is controlled to drive the linkage mechanism to move the air guide plate to the right side of the air outlet and to tilt the vertical air guide strip group to the left.

[0013] When the anti-direct-blow type is left-side anti-direct-blow, the motor drives the linkage mechanism to move the air guide plate to the left side of the air outlet and to tilt the vertical air guide strip group to the right.

[0014] Optionally, the air outlet is provided with two air guide plates, namely a first air guide plate and a second air guide plate. The vertical air guide strip group includes a first air guide strip distributed on the left side of the air outlet and a second air guide strip distributed on the right side of the air outlet. The first air guide plate and the first air guide strip are driven by a first linkage mechanism, and the second air guide plate and the second air guide strip are driven by a second linkage mechanism. The step of controlling the motor to drive the linkage mechanism to move the air guide plate to the target position corresponding to the target area according to the anti-direct blowing type, and driving the vertical air guide strip group to rotate to the target angle corresponding to the target area, further includes:

[0015] When the anti-direct-blow type is positive anti-direct-blow, the first motor is controlled to drive the first linkage mechanism to move the first air guide plate to the middle position of the air outlet and to tilt the first air guide strip to the left.

[0016] The second motor is controlled to drive the second linkage mechanism to move the second air guide plate to the middle position of the air outlet and to tilt the second air guide strip to the right.

[0017] Optionally, the steps of controlling the motor to drive the linkage mechanism to move the air guide plate to the target position corresponding to the target area according to the anti-direct-blow type, and driving the vertical air guide strip group to rotate to the target angle corresponding to the target area, further include:

[0018] When the anti-direct-blow type is full anti-direct-blow, the first motor is controlled to drive the first linkage mechanism to move the first air guide plate to the middle position of the air outlet and to tilt the first air guide strip to the left.

[0019] The second motor is controlled to drive the second linkage mechanism to move the second air guide plate to the middle position of the air outlet and to tilt the second air guide strip to the right;

[0020] When the current operating mode of the air conditioner is cooling mode, control the horizontal air guide plate of the air conditioner to rotate upward to the maximum angle;

[0021] When the current operating mode is heating mode, the horizontal air guide plate of the air conditioner is controlled to rotate downward to the maximum angle.

[0022] Optionally, the sweeping area includes a first area, a second area, and a third area, which are arranged sequentially from left to right of the air outlet. The step of determining the anti-direct-blow type based on the target area includes:

[0023] When the target area is the second area, the anti-direct-blow type is right-side anti-direct-blow.

[0024] When the target area is the first area, the anti-direct-blow type is left anti-direct-blow;

[0025] When the target area is the third area, the anti-direct-blow type is the positive anti-direct-blow type;

[0026] When the target area includes the sweeping area of ​​the air outlet, the anti-direct-blow type is the full anti-direct-blow type.

[0027] Optionally, during the operation of the anti-direct-blow mode, the step of determining the target area where the user is located includes:

[0028] During the operation of the anti-direct-blow mode, the target area is determined according to the area selected by the user's operation;

[0029] Alternatively, the user's location can be detected, and the area where the user's location is located can be determined as the target area.

[0030] Optionally, during the operation of the anti-direct-blow mode, the step of determining the target area where the user is located includes:

[0031] During the operation of the anti-direct-blow mode, user information in the sweeping area of ​​the air outlet is detected sequentially;

[0032] When the user information is detected in the third region, the target region where the user is located is determined to be the third region;

[0033] When the user information is not detected in the third region and the user information is also not detected in the first region, the target region is determined to be the second region.

[0034] When the user information is not detected in the third region and the user information is also not detected in the second region, the target region is determined to be the first region.

[0035] Optionally, during the operation of the anti-direct-blow mode, the step of determining the target area where the user is located includes:

[0036] During the operation of the anti-direct-blow mode, if it is determined that the target area where the user is located is different from the previously detected user location area, the motor drives the linkage mechanism to rotate the air guide plate and the vertical air guide strip group according to the positive anti-direct-blow control.

[0037] After a preset time interval, determine whether the user's current location is consistent with the target area;

[0038] If so, then the step of controlling the motor to drive the linkage mechanism to rotate the air guide plate and the vertical air guide strip group according to the anti-direct blowing type, so that the air outlet outlet direction is directed towards the area other than the target area, is executed.

[0039] Optionally, after determining the type of direct-blow protection based on the target area, the method further includes:

[0040] The fan speed of the air conditioner is determined according to the type of direct airflow prevention.

[0041] The indoor fan of the air conditioner is controlled to rotate according to the fan speed.

[0042] The present invention also provides an air conditioner, the air conditioner including a memory, a processor, and a control program stored in the memory and executable on the processor, the control program implementing the various steps of the control method of the air conditioner as described above when executed by the processor.

[0043] The present invention also provides a computer-readable storage medium storing a control program, which, when executed by a processor, implements the various steps of the control method for an air conditioner as described above.

[0044] The present invention provides a control method for an air conditioner, an air conditioner, and a computer-readable storage medium. During operation in anti-direct-blow mode, the air conditioner determines the target area where the user is located and then determines the anti-direct-blow type based on the target area. Then, according to the anti-direct-blow type, the motor drives the linkage mechanism to rotate the air guide plate and the vertical air guide strip assembly, so that the air outlet direction is directed towards areas other than the target area. The anti-direct-blow type corresponds to the target area; for example, anti-direct-blow means preventing direct airflow to the target area, such as left anti-direct-blow or right anti-direct-blow. The combination of the air guide plate and the vertical air guide strip assembly directs the airflow away from the user's area and towards areas other than the target area, avoiding excessively low airflow that could lead to insufficient air conditioner capacity. In other words, this embodiment achieves excellent anti-direct-blow effect while ensuring sufficient heat exchange capacity of the air conditioner. Attached Figure Description

[0056] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0057] It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0058] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the invention to those skilled in the art.

[0059] Since single-flow cabinet air conditioners cannot adjust the airflow direction, their anti-direct-blow function is generally achieved by adjusting the upward swing of the horizontal air guide plate assembly and / or reducing the fan speed. In actual use, it has been found that adjusting the upward swing of the horizontal air guide plate assembly is less effective at preventing direct blows, and combining this with reducing the fan speed results in a decrease in the air conditioner's output air volume, leading to insufficient air conditioning capacity.

[0060] Based on this, this embodiment achieves multiple types of anti-direct-blow by linking the air guiding structure (large air guide plate and vertical air guide strip). Different anti-direct-blow types are adopted according to the user's location. The anti-direct-blow type is adapted to the user's location, so that no matter where the user is, he can feel the best anti-direct-blow effect without having to reduce the fan speed too much to maintain the heat exchange capacity of the air conditioner.

[0061] Alternatively, please refer to Figures 3 to 6 The air conditioner includes an air guide plate 10 disposed at the air outlet and a vertical air guide strip assembly 20 disposed within the air outlet. A linkage mechanism 30 is provided between the air guide plate 10 and the air guide strips of the vertical air guide strip assembly 20. The linkage mechanism 30 is driven by the motor of the air conditioner.

[0062] The air guide plate 10 can move horizontally along the air outlet. When the air guide plate 10 moves to the air outlet, it can block the air outlet. When the air guide plate 10 moves to the edge of the air outlet, it can open the air outlet. The vertical air guide strip assembly 20 is disposed inside the air outlet. When the vertical air guide strip assembly 20 swings inside the air outlet, it can adjust the air outlet direction.

[0063] In one embodiment, the air outlet has only one air guide plate 10, and the air guide plate 10 is linked to the vertical air guide strip assembly 20 through the linkage mechanism 30. When the motor drives the air guide plate 10 to rotate, the linkage mechanism 30 drives the vertical air guide strip assembly 20 to rotate.

[0064] Optionally, in some embodiments, the air outlet is provided with two air guide plates 10, namely a first air guide plate 11 and a second air guide plate 12, and the vertical air guide strip group 20 includes a first air guide strip 21 and a second air guide strip 22. The first air guide strip 21 is located on the same side as the first air guide plate 11, and the second air guide strip 22 is located on the same side as the second air guide plate 12. The first air guide plate 11 and the first air guide strip 21 are connected by a first linkage mechanism (the air conditioner is provided with two linkage mechanisms 30, namely a first linkage mechanism and a second linkage mechanism) and driven by a first motor (the air conditioner is provided with two motors, namely a first motor and a second motor). The second air guide plate and the second air guide strip are connected by a second linkage mechanism and driven by a second motor.

[0065] Optionally, such as Figure 5 As shown, the linkage mechanism 30 includes a gear 31 and a rack 32. The gear 31 is mounted on the output shaft of the motor and is a long gear. Part of the gear 31 meshes with the rack 32, and part of the gear 31 meshes with the connecting teeth on the vertical air guide strip assembly 20. The rack 32 is connected to the air guide plate 10 to realize the linkage between the air guide plate 10 and the vertical air guide strip assembly 20.

[0066] The motor drives the gear 31 to rotate, the gear 31 drives the rack 32 to move, the rack 32 drives the air guide plate 10 to move, and the gear 31 simultaneously drives the vertical air guide strip assembly 20 to move. Optionally, in one embodiment, the gear 31 is located between the rack 32 and the vertical air guide strip assembly 20. In this way, the gear 31 drives the rack 31 and the vertical air guide strip assembly 20 to rotate in opposite directions. For example, when the air guide plate 10 moves to the left, the vertical air guide strip assembly 20 tilts to the right, and when the air guide plate 10 moves to the right, the vertical air guide strip assembly 20 tilts to the left.

[0067] Alternatively, in another embodiment, please refer to Figure 7 The rack can also be a large gear 33, the diameter of which is larger than the diameter of the gear 31.

[0068] Based on the above-described air conditioner structure, the present invention provides a control method for the air conditioner.

[0069] As one implementation method, the hardware environment architecture involved in the control method of the air conditioner can be as follows: Figure 1 As shown.

[0070] Specifically, the hardware architecture involved in the control method of the air conditioner may include a control terminal, which may be the air conditioner itself or a control device for the air conditioner, such as a central screen or a mobile terminal.

[0071] In one implementation, the control terminal includes: a processor 101, such as a CPU, a memory 102, and a communication bus 103. The communication bus 103 is used to establish communication between these components. The processor 102 is used to invoke an application program to execute the control process.

[0072] The memory 102 can be a high-speed RAM or a stable memory (non-volatile memory), such as a disk storage device.

[0073] It is understood that, in one embodiment, the control program that implements the control process of the air conditioner is stored in the memory 102 of the controller. When the processor 101 calls the control program from the memory 102, it performs the following operations:

[0074] During the operation of the anti-direct-blowing mode, the target area where the user is located is determined;

[0075] The type of direct air protection is determined based on the target area, wherein the type of direct air protection includes at least one of right direct air protection, left direct air protection, front direct air protection, and full direct air protection;

[0076] According to the anti-direct-blow type, the motor drives the linkage mechanism to rotate the air guide plate and the vertical air guide strip assembly so that the air outlet outlet direction is directed towards an area other than the target area.

[0077] Alternatively, in another embodiment, the control program that implements the control process of the air conditioner is stored in a computer-readable storage medium. When the storage medium is applied to a computer, the computer's processor 101 can invoke the control program from the storage medium to perform the following operations:

[0078] During the operation of the anti-direct-blowing mode, the target area where the user is located is determined;

[0079] The type of direct air protection is determined based on the target area, wherein the type of direct air protection includes at least one of right direct air protection, left direct air protection, front direct air protection, and full direct air protection;

[0080] According to the anti-direct-blow type, the motor drives the linkage mechanism to rotate the air guide plate and the vertical air guide strip assembly so that the air outlet outlet direction is directed towards an area other than the target area.

[0081] Based on the above hardware architecture, various embodiments of the air conditioner control method of the present invention are proposed.

[0082] In the first embodiment, taking an air conditioner with only one air guide plate at its air outlet as an example:

[0083] Please refer to Figure 2 The air conditioner control method proposed in this embodiment includes the following steps:

[0084] Step S10: During the operation of the anti-direct-blow mode, determine the target area where the user is located;

[0085] Step S20: Determine the type of direct airflow prevention based on the target area;

[0086] The type of direct-blowing protection includes at least one type of right-side direct-blowing protection and left-side direct-blowing protection;

[0087] Step S30: Control the motor to drive the linkage mechanism to rotate the air guide plate and the vertical air guide strip assembly according to the anti-direct blowing type, so that the air outlet outlet direction is directed towards the area other than the target area.

[0088] Optionally, in one embodiment, the step of controlling the motor to drive the linkage mechanism to rotate the air guide plate and the vertical air guide strip assembly according to the anti-direct-blow type, so that the air outlet direction is directed towards an area other than the target area, includes:

[0089] According to the anti-direct-blow type, the motor drives the linkage mechanism to move the air guide plate to the target position corresponding to the target area, and drives the vertical air guide strip group to rotate to the target angle corresponding to the target area.

[0090] The target area is the area where the user is located. In this embodiment, the air guide plate is moved to the target position corresponding to the target area to prevent airflow from exiting at the target position, thus achieving the effect of preventing direct airflow. Simultaneously, the linkage mechanism also drives the vertical air guide strip assembly to rotate to the target angle corresponding to the target area, such as directing the airflow to other areas outside the target area, to further improve the effect of preventing direct airflow in the target area, while maintaining airflow and preventing a decrease in the air conditioner's capacity.

[0091] Based on the above steps, this embodiment will be described using an air conditioner as an example.

[0092] The air conditioner includes an air guide plate disposed at the air outlet and a vertical air guide strip assembly disposed within the air outlet. A linkage mechanism is provided between the air guide plate and the air guide strips of the vertical air guide strip assembly, and the linkage mechanism is driven by the motor of the air conditioner.

[0093] Optionally, in an embodiment with only one air guide plate, the air guide plate is linked with the vertical air guide strip group, the vertical air guide strip group including at least one air guide strip, and all the air guide strips rotate synchronously.

[0094] Based on the linkage control of the air guiding structure of the air conditioner, the anti-direct-blow type of the air conditioner includes at least right-side anti-direct-blow and left-side anti-direct-blow. Here, left and right refer to the left and right sides of the air outlet when the user is facing the air conditioner.

[0095] Optionally, the anti-direct-blow type is an anti-direct-blow type adapted to the user's current location. When the anti-direct-blow type is used for air supply, it can achieve the purpose of effectively preventing direct-blows at the user's location and ensuring the heat exchange capacity of the air conditioner.

[0096] Optionally, the anti-direct-blow type of the air conditioner described in this embodiment is formed by the different rotation angles of the air guide plate and the vertical air guide strips. The following are some embodiments of the positions of the air guide plates and the rotation angles of the vertical air guide strip assembly corresponding to the anti-direct-blow type:

[0097] (a) The type of protection against direct airflow is right-side direct airflow protection. Please refer to [the relevant documentation]. Figure 3 :

[0098] Optionally, the anti-direct-blow type is right-side anti-direct-blow, and the steps of controlling the motor to drive the linkage mechanism to move the air guide plate to the target position corresponding to the target area according to the anti-direct-blow type, and driving the vertical air guide strip group to rotate to the target angle corresponding to the target area include:

[0099] The motor drives the linkage mechanism to move the air guide plate to the right side of the air outlet and to tilt the vertical air guide strip assembly to the left.

[0100] That is, by controlling the air guide plate 10 to move to the right side of the air outlet, the vertical air guide strip group 20 tilts to the left, so that the right side is blocked by the air guide plate 10. After the vertical air guide strip group 20 tilts to the left, the air is directed to the left side, forming a right-side anti-direct blowing, and the left-side air outlet ensures that the heat exchange capacity of the air conditioner will not be reduced.

[0101] Optionally, when the user is positioned on the right side of the air outlet, the right-side direct-blow protection mechanism prevents the user from being directly exposed to the wind, thus improving the direct-blow protection effect. Meanwhile, the left-side airflow guidance prevents the airflow from dropping too low, which could affect the air conditioner's heat exchange capacity.

[0102] Optionally, in one embodiment, the tilt angle of the vertical guide vane group 20 is a first angle, the magnitude of which is determined based on the moving position of the guide vane 10.

[0103] (ii) The type of protection against direct airflow is left-side direct airflow protection. Please refer to [the relevant documentation]. Figure 4 :

[0104] When the anti-direct-blow type is left-side anti-direct-blow, the steps of controlling the motor to drive the linkage mechanism to move the air guide plate to the target position corresponding to the target area according to the anti-direct-blow type, and driving the vertical air guide strip group to rotate to the target angle corresponding to the target area include:

[0105] The motor is controlled to drive the linkage mechanism to move the air guide plate to the left side of the air outlet and to tilt the vertical air guide strip assembly to the right.

[0106] That is, by controlling the air guide plate 10 to move to the left side of the air outlet, the vertical air guide strip group 20 tilts to the right, so that the left side is blocked by the air guide plate 10. After the vertical air guide strip group 20 tilts to the right, the air is directed to the right side, forming a left-side anti-direct blowing, and the right-side air outlet ensures that the heat exchange capacity of the air conditioner will not be reduced.

[0107] Optionally, when the user is positioned on the right side of the air outlet, the right-side direct-blow protection mechanism prevents the user from being directly exposed to the wind, thus improving the direct-blow protection effect. Meanwhile, the left-side airflow guidance prevents the airflow from dropping too low, which could affect the air conditioner's heat exchange capacity.

[0108] Optionally, in one embodiment, the tilt angle of the vertical guide vane group 20 is a second angle, and the magnitude of the first angle is determined based on the moving position of the guide vane 10.

[0109] Optionally, in this embodiment, the air outlet's sweeping area includes a first area and a second area, with the vertical line of the air outlet as the dividing line, the area to the left of the air outlet being the first area, and the area to the right of the air outlet being the second area.

[0110] The step of determining the type of direct airflow protection based on the target area includes:

[0111] When the target area is the second area, the anti-direct-blow type is right-side anti-direct-blow.

[0112] When the target area is the first area, the anti-direct-blow type is left anti-direct-blow.

[0113] That is, when the user is in the first area, the air conditioner's anti-direct-blow type is determined to be left anti-direct-blow. At this time, the air guide plate of the air conditioner is controlled to move to the left side of the air outlet, and the vertical air guide strip group is tilted to the right to guide the air to the second area, so as to avoid the air blowing directly on the user in the first area.

[0114] When the user is located in the second area, the air conditioner's anti-direct-blow type is determined to be right-side anti-direct-blow. At this time, the air guide plate of the air conditioner is moved to the right side of the air outlet, while the vertical air guide strip group tilts to the left to guide the air to the first area, so as to avoid the air blowing directly on the user in the second area.

[0115] Optionally, in some embodiments, the target location of the user can be determined based on the selection area corresponding to the user's selection operation. For example, when the user turns on the air conditioner, they can select the anti-direct-blow area through the air conditioner control panel or the remote control, and the selected anti-direct-blow area is determined as the target area, and then the anti-direct-blow type is determined based on the target area.

[0116] Alternatively, in some embodiments, the target area where the user is located can be determined by real-time detection of the user's actual location. For example, if the air conditioner is equipped with a smart sensor for detecting a person's location, the target area where the user is located is determined based on this smart sensor detection. After the air conditioner is turned on, or after switching to anti-direct-blow mode, the smart sensor detects the user's location in real-time or periodically, and determines the area where the user is located as the target area. For example, if the air conditioner's airflow area includes a first area and a second area, if the user is located in the first area, then the target area is determined to be the first area; if the user is located in the second area, then the target area is determined to be the second area.

[0117] Optionally, the method for checking the target area where the user is located includes, but is not limited to, the following:

[0118] In one embodiment, during the operation of the anti-direct-blowing mode, the step of determining the target area where the user is located includes:

[0119] During the operation of the anti-direct-blow mode, user information in the sweeping area of ​​the air outlet is detected sequentially;

[0120] When the user information is detected in the first region, the target region where the user is located is determined to be the first region.

[0121] If the user information cannot be detected in the first region, the target region where the user is located is determined to be the second region.

[0122] In other words, by scanning the first and second regions in a fixed order, either from left to right or from right to left, the region where user information is detected determines the target location of the user. This, in turn, determines the type of direct-blow protection.

[0123] Based on this, during the operation of the anti-direct-blow mode, the air conditioner determines the target area where the user is located and then determines the anti-direct-blow type based on the target area. Then, according to the anti-direct-blow type, it controls the motor to drive the linkage mechanism, causing the air guide plate and the vertical air guide strip assembly to rotate, so that the air outlet direction is directed towards areas other than the target area. The anti-direct-blow type corresponds to the target area; for example, anti-direct-blow means preventing direct airflow to the target area, such as left anti-direct-blow or right anti-direct-blow. The combination of the air guide plate and the vertical air guide strip assembly directs the airflow away from the user's area and towards areas other than the target area, avoiding excessively low airflow that could lead to insufficient air conditioner capacity. In other words, this embodiment achieves excellent anti-direct-blow effect while ensuring sufficient heat exchange capacity of the air conditioner.

[0124] In the second embodiment, the air outlet of the air conditioner is provided with two air guide plates as an example.

[0125] In this embodiment, the air outlet is provided with two air guide plates, namely a first air guide plate and a second air guide plate. The vertical air guide strip group includes a first air guide strip distributed on the left side of the air outlet and a second air guide strip distributed on the right side of the air outlet. The first air guide plate and the first air guide strip are driven by a first linkage mechanism, and the second air guide plate and the second air guide strip are driven by a second linkage mechanism.

[0126] Based on this, the combined control of the first air guide plate and the first air guide strip, and the second air guide plate and the second air guide strip, can increase the types of direct air protection, including both positive and full direct air protection.

[0127] That is, the types of direct-blow protection also include positive direct-blow protection and full direct-blow protection.

[0128] Alternatively, please refer to Figure 8 The steps of controlling the motor to drive the linkage mechanism to move the air guide plate to the target position corresponding to the target area according to the anti-direct-blow type, and driving the vertical air guide strip group to rotate to the target angle corresponding to the target area, further include:

[0129] Step S31: When the anti-direct-blow type is positive anti-direct-blow, control the first motor to drive the first linkage mechanism to move the first air guide plate to the middle position of the air outlet and to tilt the first air guide strip to the left.

[0130] Step S32: Control the second motor to drive the second linkage mechanism to move the second air guide plate to the middle position of the air outlet and to tilt the second air guide strip to the right.

[0131] It should be noted that steps S31 and S32 can be executed simultaneously, or S31 can be executed first and then S32, or S32 can be executed first and then S31. That is, the execution order of S31 and S32 is not limited.

[0132] Step S33: When the anti-direct-blow type is full anti-direct-blow, control the first motor to drive the first linkage mechanism to move the first air guide plate to the middle position of the air outlet and to tilt the first air guide strip to the left.

[0133] Step S34: Control the second motor to drive the second linkage mechanism to move the second air guide plate to the middle position of the air outlet and to tilt the second air guide strip to the right;

[0134] Step S35: When the current operating mode of the air conditioner is cooling mode, control the horizontal air guide plate of the air conditioner to rotate upward to the maximum angle;

[0135] Step S36: When the current operating mode is heating mode, control the horizontal air guide plate of the air conditioner to rotate downward to the maximum angle.

[0136] It should be noted that the execution order of steps S33 to S36 is not limited to the above-mentioned order. Steps S33 to S36 can be executed simultaneously or sequentially, but the sequential execution order is not limited to the order listed above.

[0137] Please refer to Figures 3 to 6 In this embodiment, based on the fact that the air conditioner includes a first air guide 11 and a second air guide plate 12, the vertical air guide strip group 20 can be divided into two groups, a first air guide strip 21 and a second air guide strip 22. Then, the first air guide plate 11 and the first air guide strip 21 are linked together, and the second air guide plate 10 and the second air guide strip 22 are linked together. In this way, through the cooperation of the first air guide plate 11, the second air guide plate 12, the first air guide strip 21 and the second air guide strip 22, at least two types of direct air protection can be added: positive anti-direct air and full anti-direct air.

[0138] In the direct-blow protection mode, the first air guide plate 11 and the second air guide plate 12 are moved relative to each other until they reach the middle position of the air outlet. During the movement of the first air guide plate 11 and the second air guide plate 12, the first air guide strip 21 is simultaneously tilted to the left to guide the air to the left side of the air outlet, and the second air guide strip 22 is simultaneously tilted to the right to guide the air to the right side of the air outlet, thereby preventing the air from blowing out from the front of the air outlet and achieving direct-blow protection. If the user is directly in front of the air outlet, adjusting the air outlet of the air conditioner through the direct-blow protection mode can effectively prevent the air from blowing directly on the user. At the same time, based on the air blowing out from the left and right sides of the air outlet, the air volume is guaranteed, thereby meeting the heat exchange capacity requirements of the air conditioner.

[0139] In the case of full-protection against direct airflow, the first air guide plate 11 and the second air guide plate 12 are moved relative to each other until they reach the middle position of the air outlet. During the movement of the first air guide plate 11 and the second air guide plate 12, the first air guide strip 21 is simultaneously tilted to the left to guide the airflow to the left side of the air outlet, and the second air guide strip 22 is simultaneously tilted to the right to guide the airflow to the right side of the air outlet, thereby preventing the air from blowing out from the front of the air outlet. At the same time, the horizontal air guide plate of the air conditioner (not shown in the figure) is rotated to guide the airflow from the air outlet upwards or downwards. If the user is in any position within the air conditioner's operating space, or if there is a person in any position within the air conditioner's operating space, they will not be blown by the airflow.

[0140] Optionally, under the full anti-direct-blow mode, the outlet air temperature can also be controlled by controlling the operating frequency of the compressor to further improve the anti-direct-blow effect. Optionally, the operating frequency of the compressor is greater than or equal to the maximum operating frequency corresponding to the current air speed of the indoor unit and less than or equal to the minimum operating frequency corresponding to the current air speed of the indoor unit.

[0141] Optionally, in one embodiment, the control method of the operating frequency of the compressor can be:

[0142] F = Fmin + (F_normal - F_min) / (F_max - F_min) * n, where 0 < n ≦ 1, n is the frequency control coefficient of the corresponding system of the air conditioner, which determines the gradient of the compressor frequency change in the anti-direct-blow mode. The change range can be preset with different parameter values according to the specific value of n for specific situations. The Fmin is the minimum operating frequency of the compressor in the normal air outlet mode (i.e., non-anti-direct-blow mode) of the air conditioner, F_max is the maximum operating frequency of the compressor in the normal air outlet mode of the air conditioner, and F_normal is the target operating frequency of the compressor in the normal air outlet mode. In this embodiment, the operating frequency of the compressor in the full anti-direct-blow mode is determined by the maximum operating frequency of the compressor in the normal air outlet mode, the minimum operating frequency of the compressor, and the target operating frequency. Combining with the control of the operating frequency of the compressor, the anti-direct-blow effect of the full anti-direct-blow is further improved.

[0143] Optionally, in one embodiment, the rotation direction of the horizontal air deflector of the air conditioner can be determined according to the current operating mode of the air conditioner.

[0144] For example, when the current operating mode of the air conditioner is the cooling mode, control the horizontal air deflector of the air conditioner to rotate upward to the maximum angle. When the current operating mode is the heating mode, control the horizontal air deflector of the air conditioner to rotate downward to the maximum angle.

[0145] That is, when the air conditioner is operating in the cooling mode, in order to avoid cold air blowing on the user, rotate the horizontal air deflector of the air conditioner upward to the maximum angle to direct the cold air to the upper space of the room. Based on the fact that cold air will sink, the indoor temperature is gradually reduced by the upper air, avoiding cold air blowing directly on the user and affecting comfort.

[0146] When the air conditioner is operating in the heating mode, rotate the horizontal air deflector of the air conditioner downward to the maximum angle to direct the hot air to the lower space of the room. Based on the fact that hot air will rise and slowly rise from the bottom, the indoor temperature gradually rises from the bottom, avoiding hot air blowing directly on the user and affecting comfort.

[0147] Optionally, in positive anti-direct-blow and full anti-direct-blow, both the first air deflector strip and the second air deflector strip are inclined at a third angle.

[0148] Alternatively, please refer to Figure 9 In this embodiment, the air outlet's sweeping area includes a first area, a second area, and a third area, arranged sequentially from left to right of the air outlet. For example, the vertical axis of the air outlet is set to 0°, the angle of swinging from 0° to the left of the air outlet is a negative angle, and the angle of swinging from the air outlet to the right is a positive angle. The area covered from -45° to -35° is the first area, the area covered from -35° to 35° is the third area, and the area covered from 35° to 45° is the second area.

[0149] Based on the fact that this embodiment can achieve left-side anti-direct-blow, right-side anti-direct-blow, frontal anti-direct-blow, and full anti-direct-blow (where left-side and right-side anti-direct-blow can be referred to in the first embodiment), it is divided into at least three swing zones. Different swing zones use different anti-direct-blow types, so that while achieving the anti-direct-blow effect, the air outlet volume is larger. If the user is in the first zone, the air conditioner is controlled to perform left-side anti-direct-blow. The air outlet sections corresponding to the second and third zones output air normally. If the user is in the second zone, the air conditioner is controlled to perform right-side anti-direct-blow, and the air outlet sections corresponding to the first and third zones output air normally. Similarly, if the user is in the third zone, the air conditioner is controlled to perform frontal anti-direct-blow, and the air outlet sections corresponding to the first and second zones output air normally.

[0150] Optionally, in this embodiment, the step of determining the type of direct airflow prevention based on the target area includes:

[0151] When the target area is the second area, the anti-direct-blow type is right-side anti-direct-blow.

[0152] When the target area is the first area, the anti-direct-blow type is left anti-direct-blow;

[0153] When the target area is the third area, the anti-direct-blow type is the positive anti-direct-blow type;

[0154] When the target area includes the sweeping area of ​​the air outlet, the anti-direct-blow type is the full anti-direct-blow type.

[0155] That is, when the user is in the first area, the air conditioner's anti-direct-blow type is determined to be left anti-direct-blow. At this time, the air guide plate of the air conditioner is controlled to move to the left side of the air outlet, and the vertical air guide strip group is tilted to the right to guide the air to the second area, so as to avoid the air blowing directly on the user in the first area.

[0156] When the user is located in the second area, the air conditioner's anti-direct-blow type is determined to be right-side anti-direct-blow. At this time, the air guide plate of the air conditioner is moved to the right side of the air outlet, while the vertical air guide strip group tilts to the left to guide the air to the first area, so as to avoid the air blowing directly on the user in the second area.

[0157] When the user is located in the third area, the air conditioner's anti-direct-blow type is determined to be positive anti-direct-blow. At this time, the first air guide plate and the second air guide plate of the air conditioner are controlled to move to the middle position of the air outlet, while the first air guide bar tilts to the left and the second air guide bar tilts to the right, so as to guide the air to the left and right sides of the air outlet and avoid the air blowing directly on the user in the third area.

[0158] When there are multiple users distributed across the first, second, and third zones, the air conditioner's anti-direct-blow type is determined to be full anti-direct-blow.

[0159] Optionally, in some embodiments, the target location of the user can be determined based on the selection area corresponding to the user's selection operation. For example, when the user turns on the air conditioner, they can select the anti-direct-blow area through the air conditioner control panel or the remote control, and the selected anti-direct-blow area is determined as the target area, and then the anti-direct-blow type is determined based on the target area.

[0160] Alternatively, in some embodiments, the target area where the user is located can be determined by real-time detection of the user's actual location. For example, if the air conditioner is equipped with a smart sensor for detecting a person's location, the target area where the user is located is determined based on this smart sensor detection. After the air conditioner is turned on, or after switching to anti-direct-blow mode, the smart sensor detects the user's location in real-time or periodically, and determines the area where the user is located as the target area. For example, if the air conditioner's airflow area includes a first area, a second area, and a third area, if the user is located in the first area, then the target area is determined to be the first area; if the user is located in the second area, then the target area is determined to be the second area; and if the user is located in the third area, then the target area is determined to be the third area.

[0161] Optionally, the method for checking the target area where the user is located includes, but is not limited to, the following:

[0162] In one embodiment, during the operation of the anti-direct-blowing mode, the step of determining the target area where the user is located includes:

[0163] During the operation of the anti-direct-blow mode, user information in the sweeping area of ​​the air outlet is detected sequentially;

[0164] When the user information is detected in the third region, the target region where the user is located is determined to be the third region;

[0165] When the user information is not detected in the third region and the user information is also not detected in the first region, the target region is determined to be the second region.

[0166] When the user information is not detected in the third region and the user information is also not detected in the second region, the target region is determined to be the first region.

[0167] In this embodiment, the air conditioner determines the target area based on whether there are people in the detected area. For example, it first detects whether there are people in the third area. If there are people, the target area is determined to be the third area, and direct airflow prevention control is applied. If there are no people in the third area, the system continues to detect the next area, such as the second area. If people are detected in the second area, the target area is determined to be the second area, and direct airflow prevention control is applied to the right. If there are no people in the second area, the target area is determined to be the first area, and direct airflow prevention control is applied to the left.

[0168] Optionally, in another embodiment, if someone is detected in the third area, while controlling the air conditioner to perform direct airflow prevention, the system continues to detect whether there is user information in the first and second areas. If there is no user information in either the first or second area, the current direct airflow prevention mode is maintained. If user information is detected in both the first and second areas, the system switches to full direct airflow prevention.

[0169] The third embodiment, based on all the above embodiments, proposes that during the anti-direct-blow control process of the air conditioner, the frequent adjustment of the air guide plate and vertical air guide strip group should be avoided when the user frequently changes positions, that is, the frequent switching of the anti-direct-blow type should be prevented, and the air guide plate and vertical air guide strip group should be avoided.

[0170] Alternatively, please refer to Figure 10 During the operation of the anti-direct-blow mode, the steps for determining the target area where the user is located include:

[0171] Step S11: During the operation of the anti-direct-blow mode, when it is determined that the target area where the user is located is different from the previously detected user location area, the motor drives the linkage mechanism to rotate the air guide plate and the vertical air guide strip group according to the positive anti-direct-blow control.

[0172] Step S12: After a preset time interval, determine whether the user's current location is consistent with the target area;

[0173] If so, then the step of controlling the motor to drive the linkage mechanism to rotate the air guide plate and the vertical air guide strip group according to the anti-direct blowing type, so that the air outlet outlet direction is directed towards the area other than the target area, is executed.

[0174] If not, then re-detect the target area where the user is located.

[0175] In this embodiment, during the operation of the anti-direct-blow mode, if it is determined that the anti-direct-blow type needs to be switched based on the target area where the user is located, the first air guide plate and the first air guide strip, the second air guide plate and the second air guide strip are first controlled to rotate in the positive anti-direct-blow type. After rotating for a preset time interval in the positive anti-direct-blow type, it is then determined whether the user has moved again in a short period of time based on the current area where the user is located. If not, the anti-direct-blow type is determined based on the target area where the user is currently located, and then the motor drives the linkage mechanism to rotate the air guide plate and the vertical air guide strip group according to the anti-direct-blow type, so that the air outlet direction is directed towards an area other than the target area. If the user moves again in a short period of time, the user's position is re-detected, and the judgment is made again based on the position after the movement.

[0176] In this embodiment, before each switch of the anti-direct-blow type, the air guide plate and the vertical air guide strip group are controlled to rotate for a preset time interval according to the positive anti-direct-blow type. Then, the anti-direct-blow type is determined according to the actual target position, and then adjusted according to the determined anti-direct-blow type. This can avoid the air guide plate and the vertical air guide strip group from running continuously due to the user changing the position continuously in a short period of time, thereby damaging the air guide plate and the air guide strip.

[0177] Optionally, the preset time interval is 30 seconds.

[0178] Fourth embodiment, based on all the above embodiments, please refer to the following embodiment. Figure 11 After the step of determining the sweeping type based on the target area where the user is located, the method further includes:

[0179] Step S30: Determine the fan speed of the air conditioner according to the anti-direct-blow type;

[0180] Step S40: Control the indoor fan of the air conditioner to rotate according to the fan speed.

[0181] In this embodiment, while controlling the rotation of the air guide plate and the vertical air guide strip, the fan rotation of the indoor unit of the air conditioner is also adjusted according to the anti-direct-blow type. The coordinated adjustment of the air guide plate, the vertical air guide strip, and the fan speed ensures optimal anti-direct-blow effect for users in various positions.

[0182] Optionally, different anti-direct-blow modes correspond to different indoor unit fan speeds. For example, the fan speed for positive anti-direct-blow and full anti-direct-blow modes is v2, the fan speed for right-side anti-direct-blow or right-side anti-direct-blow mode is v3, and the fan speed for normal airflow mode is v1. It can be understood that after the anti-direct-blow mode is exited, it switches to normal airflow mode. Optionally, v2 > v3 > v1.

[0183] It should be noted that the above are merely preferred embodiments of the present invention and do not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
