Among them, air conditioners have become the first choice of many families due to their high concealment and low price. At present, during the cooling operation of the air conditioner, the air conditioner continuously discharges air to the air outlet area through the air outlet. When the temperature is low, in order to avoid the problem of cold air outlet, a three-dimensional (3D) air guide plate is usually installed. That is, when the indoor temperature is low and the cold feeling is obvious, vertical guide vanes with micro holes are set on the closed panel to perform windless cooling.

When the air conditioner is in cooling operation, the duct unit supplies air through the air outlet, and then controls the closing of the three-dimensional air guide plate when the indoor ambient temperature is low to lower the cooling output of the air conditioner. The three-dimensional air guide plate is usually expensive due to its complex structure. At the same time, the installation of the three-dimensional air guide plate will affect the indoor home decoration effect, thereby affecting the user experience. If a hidden installation is performed, the cost will undoubtedly increase. In this way, even if the current three-dimensional air guide plate can achieve windless cooling, the cost of windless cooling of the air conditioner will be high.

[0052] When the first temperature difference is less than a first preset temperature difference, the air guide plate is controlled to rotate to control the air volume of the second air outlet.

[0053] Alternatively, in another embodiment, a control program for implementing 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 processor 1001 of the computer can call the control program from the storage medium and perform the following operations:

[0055] Acquire the indoor ambient temperature where the air conditioner is located, and determine a first temperature difference between the indoor ambient temperature and the set temperature of the air conditioner;

[0056] When the first temperature difference is less than a first preset temperature difference, the air guide plate is controlled to rotate to control the air volume of the second air outlet.

[0057] Taking a multi-split duct machine as an example, in one embodiment, refer to Figure 2The multi-connected air duct machine includes a housing 100, an air inlet 200, a heat exchanger 300, a water tray 400, a perforated air guide plate 500, a non-perforated air guide plate 600, a side air outlet 700 and a lower air outlet 800; wherein the perforated air guide plate 500 and the non-perforated air guide plate 600 are both rotatably installed at a preset position of the multi-connected air duct machine, and the perforated air guide plate 500 and the non-perforated air guide plate 600 rotate along the same center of a circle, and the perforated air guide plate 500 and the non-perforated air guide plate 600 rotate by rotating. The perforated air guide plate 500 or the non-perforated air guide plate 600 is moved to block or conduct the air outlet (the side air outlet 700 or the lower air outlet 800), the perforated air guide plate 500 and the non-perforated air guide plate 600 can be stacked, and the perforated air guide plate 500 is slidably connected to the non-perforated air guide plate 600, so that the perforated air guide plate 600 can slide out relatively along the width direction of the non-perforated air guide plate 500 or be accommodated on the plate surface of the non-perforated air guide plate 600; refer to Figure 3 , Figure 3 The figure is a schematic diagram of the structure of a perforated air guide plate and a non-perforated air guide plate, wherein the perforated air guide plate and the non-perforated air guide plate have the same size, and a certain number of ventilation holes are provided on the perforated air guide plate.

[0058] Based on the hardware architecture of the terminal, various embodiments of the air outlet control method of the air conditioner of the present invention are proposed.

[0059] Reference Figure 4 , a first embodiment of the air outlet control method of the air conditioner of the present invention is proposed. In this embodiment, the air outlet control method of the air conditioner includes:

[0060] Step S10, when the air conditioner is in cooling operation, each of the air outlets is divided into a first air outlet blocked by the non-porous air guide plate and a second air outlet not blocked by the air guide plate;

[0061] Step S20, obtaining the indoor ambient temperature where the air conditioner is located, and determining a first temperature difference between the indoor ambient temperature and the set temperature of the air conditioner;

[0062] Step S30: When the first temperature difference is less than a first preset temperature difference, the air guide plate is controlled to rotate to control the air volume of the second air outlet.

[0063] The embodiment of the present invention may be executed in an air conditioner, or in a control terminal of the air conditioner. This embodiment is described by taking the execution in the air conditioner as an example.

[0064] Optionally, the air duct unit of the air conditioner is provided with multiple air outlets, any of which can supply air to the corresponding air supply area. For example, in an implementable manner, the air duct unit is provided with a side air outlet and a lower air outlet, and is provided with a perforated air guide plate and a non-perforated air guide plate, wherein the lower air outlet is used to supply air to the area directly below the indoor unit of the air conditioner, and the side air outlet is used to supply air to the front and lower area of ​​the indoor unit of the air conditioner; when the air conditioner is in cooling operation, the air conditioner can control the perforated air guide plate and the non-perforated air guide plate to rotate respectively through a motor, and then can independently control the non-perforated air guide plate to rotate to a first designated position to block the air outlet of the side air outlet, and independently control the perforated air guide plate to rotate to a second designated position to not block the air outlet of the lower air outlet. At this time, the two air outlets of the air duct unit It is divided into a first air outlet (side air outlet) blocked by a non-porous air guide plate and a second air outlet (lower air outlet) not blocked by an air guide plate (a non-porous air guide plate or a perforated air guide plate). When the perforated air guide plate rotates to a first designated position, the cold air leading to the first air outlet will have its wind direction changed by the perforated air guide plate, that is, the air duct unit of the air conditioner only delivers cold air to the air supply area of ​​the indoor space corresponding to the air conditioner through the lower air outlet, so as to continuously reduce the indoor ambient temperature of the air conditioner. Both the perforated air guide plate and the non-porous air guide plate can be arranged in an arc shape. The first designated position can be a position where the arc section of the non-porous air guide plate is tangent to the air duct wall of the side air outlet. The second designated position can be a position where a first perpendicular line from the center of the rotation circle to the arc surface of the perforated air guide plate and a second perpendicular line from the center of the rotation circle to the non-porous air guide plate are 180° apart.

[0065] Optionally, the first preset temperature difference is a preset critical value of the temperature difference between the indoor ambient temperature and the set temperature of the air conditioner for determining that the air volume of the second air outlet needs to be adjusted. The first preset temperature difference can be 2°C or any temperature value between 0-2°C.

[0066] Optionally, during the cooling process of the air conditioner, the indoor ambient temperature will be gradually lowered as the cooling time increases, and when the indoor ambient temperature drops to a certain value, the cold air output through the second air outlet will have a noticeable cool feeling. Therefore, during the cooling operation of the air conditioner, the first preset temperature difference is used to determine whether the cold air currently output from the second air outlet will have a noticeable cool feeling. At this time, in order to achieve windless cooling, the air guide plate needs to be rotated to reduce the air volume output from the second air outlet.

[0067] Optionally, in one embodiment, when a first temperature difference between the indoor ambient temperature and the set temperature of the air conditioner is less than a first preset temperature difference, the second air outlet is blocked by rotating the perforated air guide plate, and the first air outlet is opened by rotating the non-perforated air guide plate to reduce the air volume output by the second air outlet.

[0068] Optionally, in another embodiment, when the first temperature difference between the indoor ambient temperature and the set temperature of the air conditioner is still less than the first preset temperature difference, the conductivity of the first air outlet is increased by rotating the hole-free air guide plate, thereby reducing the air volume output from the second air outlet, wherein the conductivity can be specifically characterized by the inclination angle between the hole-free air guide plate and the air duct wall corresponding to the first air outlet.

[0069] Optionally, in another embodiment, when the first temperature difference between the indoor ambient temperature and the set temperature of the air conditioner is still less than the first preset temperature difference, the non-porous air guide plate is rotated to the position where the perforated air guide plate blocks the second air outlet, and air is discharged through the first air outlet to reduce the air volume output by the second air outlet.

[0070] Optionally, in one embodiment, when the air conditioner is in cooling operation, the indoor ambient temperature of the air conditioner is obtained, and a first temperature difference between the indoor ambient temperature and the set temperature of the air conditioner is determined. When the temperature difference between the indoor ambient temperature and the set temperature of the air conditioner is less than the first preset temperature difference, the second air outlet is blocked by rotating the perforated air guide plate to reduce the air volume output from the second air outlet.

[0071] Optionally, in another embodiment, when the first temperature difference between the indoor ambient temperature and the set temperature of the air conditioner is less than a first preset temperature difference, the second air outlet is blocked by rotating the perforated air guide plate, and when the first temperature difference between the indoor ambient temperature and the set temperature of the air conditioner is less than the first preset temperature difference, the position of the perforated air guide plate is kept unchanged, and the air volume output from the second air outlet is reduced by reducing the ventilation area of ​​the perforated air guide plate.

[0072] Optionally, in another embodiment, when a first temperature difference between the indoor ambient temperature and the set temperature of the air conditioner is less than a first preset temperature difference, the ventilation holes of the perforated air guide plate are increased, the ventilation area of ​​the perforated air guide plate is reduced, and the air volume output from the second air outlet is reduced.

[0073] Optionally, in another embodiment, when a first temperature difference between the indoor ambient temperature and the set temperature of the air conditioner is less than a first preset temperature difference, the ventilation area of ​​the perforated air guide plate is reduced by reducing the opening of the air holes of the perforated air guide plate, thereby reducing the air volume output from the second air outlet.

[0074] Optionally, in one embodiment, when a first temperature difference between the indoor ambient temperature and the set temperature of the air conditioner is less than a first preset temperature difference, it is determined that an increase in the air holes of the perforated air guide plate is reduced, and the air holes of the perforated air guide plate are increased according to the increase. For example, when the first temperature difference is 3°C and the number of air holes is 100, the increase is determined to be 50, then the number of air holes is adjusted to 150, and the number of air holes is increased at one time directly according to the first temperature difference. Since the air outlet of the duct air conditioner is constant, as the number of air holes of the perforated air guide plate increases, the air volume of the second air outlet is more dispersedly delivered to the air supply area, thereby reducing the cold feeling in the process of lowering the temperature, thereby improving the effect of no wind feeling. However, it is easy for the cooling effect to change significantly due to excessive increase in a single adjustment.

[0075] Optionally, in another embodiment, an increase in the number of air holes of the perforated air guide plate is determined according to a first temperature difference between the indoor ambient temperature and the set temperature, the number of air holes is increased according to the increase, the change in the first temperature difference between the indoor ambient temperature and the set temperature is obtained, an adjustment amount of the increase is determined according to the change, the increase is adjusted according to the adjustment, and the execution step is returned: according to the increase, the number of air holes is increased until the first temperature difference is less than the first preset temperature difference. For example, the first temperature difference is 4°C, the number of air holes is 100, and the increase is determined to be 15, then the number of air holes is adjusted to 115. The first temperature difference is reduced to 3°C, then the change is 1°C, and the adjustment amount of the increase is determined to be 5, then the adjustment amount is 5, and then the number of air holes is adjusted to 120. By determining the first temperature difference between the indoor ambient temperature and the set temperature in real time and adjusting the increase, the number of air holes is further adjusted, thereby avoiding a one-time increase that is too large, resulting in a significant change in the cooling effect.

[0076] Optionally, in one embodiment, the holeless air guide plate and the holed air guide plate are controlled to overlap, and after the holeless air guide plate and the holed air guide plate overlap, the air outlet is divided into the first air outlet and the second air outlet by controlling the holeless air guide plate and the holed air guide plate to rotate together to a first preset position.

[0077] It is easy to understand that in the process of dividing the first air outlet and the second air outlet, the perforated air guide plate and the non-perforated air guide plate can be located at different positions, so as to achieve blocking one or more air outlets to obtain the first air outlet, and not blocking one or more air outlets to obtain the second air outlet. However, when the non-perforated air guide plate and the perforated air guide plate are in different positions, since the position of the non-perforated air guide plate needs to be limited to obtain the first air outlet, and the position of the perforated air guide plate is not limited, the perforated air guide plate located inside the duct machine will change the outlet direction of part of the cold air output by the duct machine through the second air outlet to a certain extent, which will lead to the amount of cold air output by the air conditioner through the second air outlet, and finally the problem of the air conditioner needing to run for a long time to achieve the preset cooling effect.

[0078] Optionally, in one embodiment, the holeless air guide plate is controlled to rotate from a first current position to a designated overlapping position, and the holeless air guide plate is controlled to rotate from a second current position to the designated overlapping position. After the holeless air guide plate and the holed air guide plate overlap at the designated overlapping position, the air outlet is divided into the first air outlet and the second air outlet by controlling the holeless air guide plate and the holed air guide plate to rotate together to a first preset position. For example, in an implementable manner, assuming that each air outlet includes a side air outlet and a lower air outlet, if the default air outlet mode of the duct air conditioner during cooling operation is the lower air outlet, the holeless air guide plate and the holed air guide plate are controlled to rotate The rotation is overlapped to the middle position, and after the overlap, it is detected whether the middle position of the rotation is the first preset position for blocking the air outlet of the side air outlet. If the middle position of the rotation is the first preset position for blocking the air outlet of the side air outlet, the first air outlet and the second air outlet are directly obtained. If the middle position of the rotation is not the first preset position for blocking the air outlet, the non-porous air guide plate and the perforated air guide plate are rotated from the middle position of the rotation to the first preset position to obtain the side air outlet blocked by the non-porous air guide plate and the perforated air guide plate, and to obtain the second air outlet that is not blocked by any air guide plate, wherein the middle position of the rotation is used to characterize the midpoint of the rotation path of the non-porous air guide plate to the perforated air guide plate. By overlapping the non-porous air guide plate and the perforated air guide plate and then rotating them to a first preset position, a second air outlet blocked by the non-porous air guide plate and the perforated air guide plate can be obtained, thereby avoiding the technical defect of prolonged cooling time due to the position of the perforated air guide plate affecting the air outlet of the second air outlet during division of the first air outlet and the second air outlet. At the same time, the overlap of the perforated air guide plate and the non-porous air guide plate will also increase the internal space of the duct machine, which is beneficial to the inlet and outlet air circulation of the air conditioner during the cooling process.

[0079] In the present embodiment, during the cooling operation of the air conditioner, the multiple air outlets of the air conditioner are divided into a first air outlet blocked by the air guide plate and a second air outlet not blocked by the non-porous air guide plate. That is, since the non-porous air guide plate can change the direction of the cold air at the first air outlet, the air conditioner normally outputs cold air through the second air outlet during the cooling operation, and then determines a first temperature difference between the indoor ambient temperature where the air conditioner is located and the set temperature of the air conditioner. When the first temperature difference is less than the first preset temperature difference, the indoor ambient temperature is about to reach the set temperature of the air conditioner. The cold air outputted from the second air outlet of the duct unit of the air conditioner may bring a noticeable cold feeling, so the perforated air guide plate is rotated to the first preset position to control the air volume of the second air outlet, that is, the cold air of the duct unit is outputted from the second air outlet through the microholes arranged on the perforated air guide plate, thereby achieving the purpose of windless cooling. Since the structures of the perforated air guide plate and the non-perforated air guide plate are simpler than those of the three-dimensional air guide plate, the purpose of replacing the three-dimensional air guide plate with the perforated air guide plate and the non-perforated air guide plate is achieved, thereby reducing the cost of windless cooling of the air conditioner.

[0080] Reference Figure 5 Based on the above embodiment, a second embodiment of the air outlet control method of the air conditioner is proposed. In this embodiment, the step S10 includes:

[0081] Step A10, obtaining a first position corresponding to the environment where the target user is located in the indoor unit of the air conditioner;

[0082] Step A20, determining a first air outlet area where the target user is located according to the first position;

[0083] Step A30: According to the first air outlet area, each of the air outlets is divided into the first air outlet and the second air outlet by rotating the non-porous air guide plate and the perforated air guide plate.

[0084] In this embodiment, the target user refers to a user located in the indoor space where the indoor unit of the air conditioner is located. The air conditioner carries a position detection device, which can be an infrared sensor or a camera, etc. The position detection device can detect the position of the target user in the environment where the indoor unit of the air conditioner is located. When the air conditioner just starts to cool, the indoor environment temperature and the set temperature of the air conditioner are usually quite different. At this time, the user needs direct cold air, and the current position of the user does not necessarily match the default air outlet mode of the air conditioner during the cooling process. For example, the user is located in the area directly below the indoor unit of the air conditioner, and the air outlet of the air conditioner at the beginning of cooling is a side outlet, which will result in the cold air not being able to be blown. The user may not feel it in time, and then the second air outlet for discharging air during the cooling process of the air conditioner needs to be accurately selected according to the user's position, so that the air supply area of ​​the second air outlet of the duct machine coincides with the user's position. For example, in one feasible method, assuming that each air outlet includes a side air outlet and a lower air outlet, when it is detected that the first air outlet area where the user is located is the front lower area of ​​the air conditioner indoor unit corresponding to the side air outlet, the side air outlet is used as the second air outlet, and the lower air outlet is used as the first air outlet, that is, the hole-free air guide plate is controlled to rotate to the first preset position to block the lower air outlet, so that the cold air is discharged through the side air outlet, and then the cold air can reach the user's body surface faster, thereby improving the user's cooling experience.

[0085] Optionally, before cooling by the air conditioner, the indoor space where the indoor unit of the air conditioner is located can be divided into multiple air outlet areas according to the air outlet direction of the air outlet, wherein the same air outlet area can be corresponded by multiple air outlets, and different air outlet areas can also be corresponded one by one by different air outlets. The target user can be one or more users. When the target user is one, the area to which the first position of the target user belongs is directly used as the first air outlet area. When the target user is multiple, the main air supply area and the secondary air supply area can be distinguished according to the number of target users in different air outlet areas, and the main air supply area is used as the first air outlet area. For example, in an implementable method, assuming that there are 4 target users in total, 2 of them are located in area A, 1 is located in area B, and 1 is located in area C, then area A is used as the first air outlet area. When there are multiple target users, the main target user can also be selected from the multiple target users, and the area where the main target user is located can be used as the first air outlet area. This embodiment does not limit this.

[0086] Optionally, in one embodiment, a first position of a target user in an environment where the indoor unit of the air conditioner is located is collected by a position detection device; the air outlet area corresponding to the area to which the first position belongs is used as the first air outlet area where the target user is located; the air outlets that supply air to the first air outlet area and the air outlets that do not supply air to the first air outlet area are determined among the air outlets, and the first air outlet and the second air outlet are obtained by rotating the holeless air guide plate to a first preset position to block the air outlets that do not supply air to the first air outlet area, and by rotating the holeless air guide plate to a second preset position to not block the air outlets that supply air to the first air outlet area.

[0087] Optionally, in another embodiment, a first position of a target user in an environment where the indoor unit of the air conditioner is located is collected by a position detection device; the air outlet area corresponding to the area to which the first position belongs is used as the first air outlet area where the target user is located; the air outlets that supply air to the first air outlet area and the air outlets that do not supply air to the first air outlet area are determined in each of the air outlets, and the holeless air guide plate and the holed air guide plate are respectively rotated to the middle rotation position to overlap the holeless air guide plate and the holed air guide plate, and then the holeless air guide plate and the holed air guide plate are controlled to rotate together from the middle rotation position to the first preset position, and the air outlet is divided into a first air outlet blocked by the holeless air guide plate and the holed air guide plate and a second air outlet not blocked by the air guide plate.

[0088] This embodiment detects in real time when the air conditioner is in cooling operation a first position of a target user corresponding to the environment of the indoor unit of the air conditioner, and then determines a first air outlet area where the target user is located according to the first position, thereby controlling the rotation of the non-porous air guide plate and the perforated air guide plate according to the first air outlet area, and obtaining a first air outlet blocked by the non-porous air guide plate and a second air outlet not blocked by the air guide plate, thereby avoiding the technical defect that the air outlet area corresponding to the air outlet does not match the area to which the target user belongs, and can achieve that when cooling starts, the cold air output through the second air outlet can quickly reach the body surface of the target user, thereby improving the user's cooling experience.

[0089] Optionally, refer to Figure 6 Based on the above embodiment, a third embodiment of the air outlet control method of the air conditioner is proposed. In this embodiment, the air outlet control method of the air conditioner further includes:

[0090] Step B10, when the first temperature difference is greater than or equal to the first preset temperature difference, controlling the perforated air guide plate and the non-perforated air guide plate to be located at a target position together.

[0091] In this embodiment, during the cooling process of the air conditioner, the indoor ambient temperature of the indoor unit of the air conditioner will continue to decrease over time. When the air conditioner starts cooling, the cold air is controlled to be output to the first air outlet area through the second air outlet so that the cold air blows directly to the target user. However, as the indoor ambient temperature decreases, if the cold air continues to blow directly to the target user, it may cause the target user to have an obvious cold feeling. In order to achieve a windless cooling effect, the indoor ambient temperature of the air conditioner can be obtained by referring to the above embodiment, and a first temperature difference between the indoor ambient temperature and the set temperature of the air conditioner can be determined. At the first temperature When the difference is less than the first preset temperature difference, the air guide plate is controlled to rotate to control the air volume of the second air outlet. For example, in one feasible method, assuming that the first preset temperature difference is 2°C, the first air outlet is the side air outlet, and the second air outlet is the lower air outlet. When the first temperature difference is less than 2°C, it means that the indoor ambient temperature is close to the set temperature of the target user. At this time, the perforated air guide plate is rotated to the third preset position to allow the cold air to be output from the second air outlet to the air outlet area through the ventilation holes on the perforated air guide plate, thereby significantly reducing the wind speed of the second air outlet and achieving a windless cooling effect.

[0092] In addition, when the first temperature difference is greater than or equal to the real-time first preset temperature difference, since the indoor ambient temperature is greatly different from the user's set temperature at this time, it is still necessary to ensure a certain air supply volume to quickly reduce the indoor ambient temperature, and then the perforated air guide plate and the non-perforated air guide plate can be controlled to be in the same position without affecting the air supply efficiency of the duct machine. For example, in one feasible method, assuming that the side air outlet is the first air outlet and the lower air outlet is the second air outlet, the perforated air guide plate and the non-perforated air guide plate are controlled to be continuously in the first preset position, so that the duct machine can supply air stably through the second air outlet.

[0093] In addition, as the indoor ambient temperature continues to drop, users already have a certain sense of coolness, and as the temperature drops, the air volume of the second air outlet needs to be reduced in real time, thereby improving the cooling experience of the target users when the indoor ambient temperature continues to drop.

[0094] Optionally, the target position includes the first preset position and the second preset position. In one embodiment, the perforated air guide plate and the non-perforated air guide plate overlap at the first preset position. When it is detected that the first temperature difference is greater than or equal to the first preset temperature difference, the perforated air guide plate and the non-perforated air guide plate are controlled to remain unchanged at the first preset position.

[0095] In one embodiment, the perforated air guide plate is located at the second designated position, and the non-perforated air guide plate is located at the first preset position, and when it is detected that the first temperature difference is greater than or equal to the first preset temperature difference, the perforated air guide plate is controlled to rotate from the second designated position to the first preset position.

[0096] In another embodiment, the perforated air guide plate and the non-perforated air guide plate overlap at a first preset position, and the air guide plate and the non-perforated air guide plate are controlled to rotate concentrically to a second preset position at a preset rotation angle, wherein the preset rotation angle can be specifically determined by the change in the first temperature difference, and the second preset position is the position of the air guide plate when the first air outlet and the second air outlet discharge air at different openings, and the preset rotation angle is inversely proportional to the air outlet volume of the second air outlet, that is, the larger the preset rotation angle, the smaller the air outlet volume of the second air outlet.

[0097] In this embodiment, when the first temperature difference is greater than or equal to the first preset temperature difference, the perforated air guide plate and the non-perforated air guide plate are controlled to be located at the target position together, that is, the perforated air guide plate and the non-perforated air guide plate are controlled to be located at the same position, and then when the indoor ambient temperature is greatly different from the set temperature of the target user, it is ensured that the duct machine continues to supply air through the second air outlet, thereby improving the cooling efficiency of the duct machine.

[0098] Optionally, refer to Figure 7 Based on the above embodiment, a fourth embodiment of the air outlet control method of the air conditioner is proposed, and step S30 includes:

[0099] Step S31, detecting whether the first temperature difference is greater than a second preset temperature difference, wherein the second preset temperature difference is less than or equal to the first preset temperature difference;

[0100] Step S32, when the first temperature difference is greater than the second preset temperature difference, controlling the non-porous air guide plate to be located at the first preset position, and controlling the perforated air guide plate to rotate to the third preset position.

[0101] It should be understood that during the cooling process of the air conditioner, the target user's perception of coldness is different at different indoor ambient temperatures. Then, when the indoor ambient temperature approaches the set temperature of the target user, the perforated air guide plate and / or the non-perforated air guide plate are controlled to rotate through different control logics to match the target user's cooling experience in different temperature difference ranges.

[0102] Optionally, in one embodiment, when the first temperature difference is greater than the second preset temperature difference, the non-porous air guide plate is controlled to be located at the first preset position so that the duct machine continues to supply air through the second air outlet, and at the same time, the perforated air guide plate is controlled to be located at the third preset position so that the duct machine only supplies air through the air vents of the perforated air guide plate via the second air outlet, thereby significantly reducing the amount of cold air in the area where the target user is located. For example, assuming that the first air outlet is a side air outlet and the second air outlet is a lower air outlet, when the first temperature difference is greater than -1°C and less than 2°C, the lower air outlet is blocked by the perforated air guide plate and the side air outlet is blocked by the non-porous air guide plate.

[0103] Optionally, after controlling the perforated air guide plate to rotate to the third preset position, dynamically detect whether a second temperature difference between the indoor ambient temperature and the set temperature of the air conditioner is less than or equal to a second preset temperature difference, wherein the second preset temperature difference is less than or equal to the first preset temperature difference; and respectively control the non-perforated air guide plate and the perforated air guide plate to rotate to obtain a third air outlet for discharging air to the second air outlet area and a fourth air outlet that does not discharge air to the second air outlet area, wherein the third air outlet may correspond to the first air outlet, and the fourth air outlet may correspond to the first air outlet. The air outlet may correspond to the second air outlet. For example, assuming that the first air outlet is a side air outlet and the second air outlet is a lower air outlet, when the first temperature difference is less than or equal to -1°C, the lower air outlet is blocked by a non-porous air guide plate and the side air outlet is blocked by a perforated air guide plate, that is, the cold air generated by the duct machine is output from the side air outlet through the air holes on the perforated air guide plate, and the cold air generated by the duct machine cannot be discharged through the lower air outlet, that is, the first air outlet is changed to the third air outlet due to the change in the position of the air guide plate, and the fourth air outlet is changed to the fourth air outlet due to the change in the position of the air guide plate. Since the air supply area of ​​the lower air outlet corresponds to the location of the target user, when the indoor ambient temperature is too low, the cold air is directly blown to the area where the non-target user is located after being weakened, thereby achieving the technical defect of reducing the amount of cold air while avoiding the direct blowing of the cold air to the target user, that is, the purpose of the windless cooling effect is fully achieved.

[0104] Optionally, before step S10, the method further includes:

[0105] Step C10, detecting whether there is a target user in the environment where the indoor unit of the air conditioner is located;

[0106] Step C20: If yes, then execute the step of obtaining the first position corresponding to the environment where the target user is located in the indoor unit of the air conditioner and subsequent steps;

[0107] Step C30: If not, then according to a preset air outlet mode, each of the air outlets is divided into a fifth air outlet blocked by the non-porous air guide plate and a sixth air outlet not blocked by the air guide plate.

[0108] It is understandable that when the air conditioner carries a position detection device, the target user may not be detected in the environment where the indoor unit of the air conditioner is located, that is, there is no user in the environment where the indoor unit of the air conditioner is located. At this time, the specific positions of the non-porous air guide plate and the perforated air guide plate can be determined by the preset air outlet mode, wherein the preset air outlet mode includes side air outlet mode, double-side air outlet mode, and downward air outlet mode, etc.

[0109] In an implementable manner, it is detected whether there is a target user in the environment where the indoor unit of the air conditioner is located; if it is detected that the target user exists in the environment where the indoor unit of the air conditioner is located, the step of obtaining the first position corresponding to the target user in the environment where the indoor unit of the air conditioner is located and the subsequent steps are performed; if it is detected that the target user does not exist in the environment where the indoor unit of the air conditioner is located, according to the preset air outlet mode, by rotating the non-porous air guide plate and / or the perforated air guide plate, each of the air outlets is divided into a fifth air outlet blocked by the non-porous air guide plate and a sixth air outlet not blocked by the air guide plate. In this way, when the target user is not detected, the air conditioner can output cold air through the sixth air outlet to meet the preset air outlet mode.

[0110] In addition, an embodiment of the present invention further proposes a computer-readable storage medium, on which a control program for an air conditioner is stored. When the control program for the air conditioner is executed by a processor, the relevant steps of any embodiment of the above air outlet control method for the air conditioner are implemented.
