Description

Technical Field

[0001] This application relates to the field of air conditioning technology, and more specifically, to an air outlet control method, device, and air conditioner. Background Technology

[0002] In existing air conditioning units, two air deflectors are used to control the airflow direction. When controlling left and right airflow, the two air deflectors remain open, meaning the airflow diverges as it passes between them, widening the airflow and reducing its speed. While this method is beneficial for wide-angle air delivery, it can easily result in the airflow distance being too short in front of the air conditioner unit (often the area where the user's main activities take place), affecting the user experience. Summary of the Invention

[0003] The problem addressed by this application is that existing air conditioners struggle to achieve both wide-angle airflow and a relatively long airflow distance in the area directly in front of the user.

[0004] To address the aforementioned problems, in a first aspect, this application provides an air outlet control method applied to an air conditioner. The air conditioner includes an air guide mechanism, which comprises a rotatable first air guide member and a second air guide member. The first air guide member has a first air guide plate, and the second air guide member has a second air guide plate. The air guide mechanism can control the air outlet direction of the air conditioner between a first limit air outlet angle and a second limit air outlet angle by adjusting the deflection angle of the first air guide plate and the second air guide plate. The air outlet control method includes:

[0005] The air guide mechanism is controlled to move according to a preset rule so that the air conditioner sweeps between the first limit air outlet angle and the second limit air outlet angle.

[0006] Specifically, when the air conditioner discharges air at the first and second extreme air discharge angles, an open main air discharge channel is formed between the first and second air guide plates. When the air conditioner discharges air in the middle air discharge zone between the first and second extreme air discharge angles, the first and second air guide plates are parallel to each other or form a gradually narrowing main air discharge channel.

[0007] The air outlet control method of this application enables the air guide mechanism to form an open main air outlet channel between the first and second air guide plates at the two extreme positions of the sweeping path, which is beneficial for the air conditioner to sweep air over a wider range. Alternatively, to achieve a wider range of air outlet angles, it is not necessary for both the first and second air guide components to deflect at large angles at their extreme positions; only one of them needs to deflect at a large angle. Since users are generally located more in front of the air conditioner, when the air conditioner outlets air in the middle air outlet section, the first and second air guide plates are parallel to each other or form a constricted main air outlet channel, which helps to increase the air delivery distance and improve the user experience for users directly in front of the air conditioner. Therefore, the air outlet control method of this application enables the air conditioner to have a wider air delivery angle and increases the air delivery distance in the area directly in front of the air conditioner, thereby improving the user experience. Furthermore, when the air conditioner outlets air at the first and second extreme air outlet angles, the open main air outlet channel formed between the first and second air guide plates also helps to prevent condensation from forming on the first and second air guide components.

[0008] In an optional embodiment, when the air conditioner is discharging air at the first and / or second extreme air outlet angles, the first and second air guide plates form an angle of 30° to 60°. By controlling the angle between the first and second air guide plates to 30° to 60°, the airflow from the air conditioner at the first and / or second extreme air outlet angles can be dispersed outwards, thereby improving the air delivery range of the air conditioner. It can be understood that a larger angle between the first and second air guide plates is more conducive to wide-angle air delivery, but at the same time, the air delivery distance is shortened. Therefore, when discharging air at the first and / or second extreme air outlet angles, an angle of 30° to 60° between the first and second air guide plates allows users at the side and front of the air conditioner to also have a better user experience, and condensation is less likely to occur on the first and second air guide plates.

[0009] In an optional embodiment, the rotation axes of the first and second air guides are parallel to each other and symmetrically arranged with respect to the central symmetry plane. The rotation axes of the first and second air guides are located on the first and second sides of the central symmetry plane, respectively. When the air conditioner discharges air at the first extreme air outlet angle, the air outlet direction is towards the first side of the central symmetry plane; when the air conditioner discharges air at the second extreme air outlet angle, the air outlet direction is towards the second side of the central symmetry plane. The first air outlet direction of the air guide mechanism at the first extreme air outlet angle and the second air outlet direction at the second extreme air outlet angle are symmetrical with respect to the central symmetry plane. In this embodiment, the central symmetry plane is parallel to the front direction of the air conditioner and parallel to the rotation axes of the first and second air guides, so that during a period of air sweeping, the overall air volume on both sides in front of the air conditioner is approximately the same, and the flow field is approximately symmetrical at the first and second extreme air outlet angles.

[0010] In an optional embodiment, when the air conditioner is discharging air at the first extreme air outlet angle, the first air guide plate forms an angle of 50° to 70° with the central plane of symmetry, and the second air guide plate forms an angle of 10° to 30° with the central plane of symmetry; when the air conditioner is discharging air at the second extreme air outlet angle, the second air guide plate forms an angle of 50° to 70° with the central plane of symmetry, and the first air guide plate forms an angle of 10° to 30° with the central plane of symmetry. Optionally, when the air conditioner is discharging air at the first extreme air outlet angle, the first air guide plate forms an angle of 60° with the central plane of symmetry, and the second air guide plate forms an angle of 20° with the central plane of symmetry; when the air conditioner is discharging air at the second extreme air outlet angle, the second air guide plate forms an angle of 60° with the central plane of symmetry, and the first air guide plate forms an angle of 20° with the central plane of symmetry. This design ensures that at both the first and second extreme air outlet angles, the first and second air guide vanes form a 40° angle, resulting in a total airflow angle range of 120°. This allows for wide-angle airflow while maintaining a certain airflow distance even at extreme positions. Furthermore, this configuration minimizes condensation on the second air guide vane at the first extreme air outlet angle and minimizes condensation on the first air guide vane at the second extreme air outlet angle.

[0011] In an optional implementation, the preset rules include:

[0012] During the process of the air conditioner's air outlet direction changing from the first extreme air outlet angle to the middle air outlet section, the first air outlet component is controlled to rotate while keeping the second air outlet component stationary, so that the first air outlet plate and the second air outlet plate are parallel to each other or form a contracting main air outlet channel; during the process of the air conditioner discharging air in the middle air outlet section, the first air outlet component and the second air outlet component are controlled to rotate simultaneously; during the process of the air conditioner's air outlet direction changing from the middle air outlet section to the second extreme air outlet angle, the rotation of the first air outlet component is stopped first, and the second air outlet component is controlled to continue rotating, so that an open main air outlet channel is formed between the first air outlet plate and the second air outlet plate.

[0013] In an optional implementation, the preset rules include:

[0014] During the process of the air conditioner's air outlet direction changing from the first extreme air outlet angle to the middle air outlet section, the first air guide and the second air guide are controlled to rotate simultaneously, and the rotation speed of the first air guide is greater than that of the second air guide, so that the first air guide plate and the second air guide plate are parallel to each other or form a contracting main air outlet channel; during the process of the air conditioner discharging air in the middle air outlet section, the first air guide and the second air guide are controlled to rotate simultaneously at the same speed; during the process of the air conditioner's air outlet direction changing from the middle air outlet section to the second extreme air outlet angle, the first air guide and the second air guide are controlled to rotate simultaneously, and the rotation speed of the second air guide is greater than that of the first air guide, so that an open main air outlet channel is formed between the first air guide plate and the second air guide plate.

[0015] By controlling the air guide mechanism using the two preset rules mentioned above, the air guide mechanism can form an open main air outlet channel at the first and second limit air outlet angles, resulting in a slower air speed and a wider air outlet range; when air is outleted in the middle air outlet section, it forms a parallel or gradually narrowing main air outlet channel, resulting in a faster air speed and a longer air delivery distance.

[0016] In an optional embodiment, the air conditioner has an air outlet, and the air outlet control method further includes:

[0017] Upon receiving a shutdown command, the air guide mechanism is controlled to block the air outlet.

[0018] The aforementioned control method allows the air guide mechanism to close the air outlet when the air conditioner is not in use, protecting the internal components and improving aesthetics. Furthermore, since the air guide mechanism serves both to achieve airflow sweeping and to close the air outlet, it simplifies the air conditioner's structure and reduces the number of components such as the motor.

[0019] In an optional embodiment, the first air guide further includes a first auxiliary plate spaced parallel to and parallel to the first air guide plate, and the second air guide further includes a second auxiliary plate spaced parallel to and parallel to the second air guide plate. The first auxiliary plate is disposed on the side of the first air guide plate facing away from the main air outlet channel, and the second auxiliary plate is disposed on the side of the second air guide plate facing away from the main air outlet channel. When the air guide mechanism blocks the air outlet, the first air guide plate and the second air guide plate jointly block the air outlet, and the first and second auxiliary plates are located inside the air conditioner. In this embodiment, by setting the first and second auxiliary plates, the air can also be guided in an auxiliary manner; by using the first and second air guide plates to jointly close the air outlet and placing the first and second auxiliary plates inside the air conditioner, the aesthetics of the air conditioner are improved.

[0020] Secondly, this application provides an air outlet control device applied to an air conditioner. The air conditioner includes an air guide mechanism, which includes a rotatable first air guide member and a second air guide member. The first air guide member has a first air guide plate, and the second air guide member has a second air guide plate. The air guide mechanism can control the air outlet direction of the air conditioner between a first limit air outlet angle and a second limit air outlet angle by adjusting the deflection angle of the first air guide plate and the second air guide plate. The air outlet control device is used for:

[0021] The air guide mechanism is controlled to rotate according to a preset rule so that the air conditioner sweeps between the first limit air outlet angle and the second limit air outlet angle.

[0022] Specifically, when the air conditioner discharges air at the first and second extreme air discharge angles, an open main air discharge channel is formed between the first and second air guide plates. When the air conditioner discharges air in the middle air discharge zone between the first and second extreme air discharge angles, the first and second air guide plates are parallel to each other or form a gradually narrowing main air discharge channel.

[0023] Thirdly, this application provides an air conditioner, including a controller, which executes executable instructions to implement the air outlet control method of any of the foregoing embodiments. Attached Figure Description

Detailed Implementation

[0029] In related technologies, two air guide vanes are used to control the airflow direction of a floor-standing air conditioner. When controlling the left and right swing of the air conditioner, the two air guide vanes maintain the same rotation speed and remain open, meaning the airflow diverges as it passes between the two vanes, widening the airflow and reducing its speed. While this method is beneficial for wide-angle air delivery, it can easily lead to the air delivery distance in the area directly in front of the air conditioner (often the user's main activity area) being too short, affecting the user experience. If, while ensuring the same swing angle range, the two air guide vanes are kept in a non-open state (i.e., parallel to each other or forming a converging air duct), then at extreme positions, both vanes have a large deflection angle, which can easily cause condensation on the vanes. For example, when the two vanes are deflected to the left extreme position, the right vane, due to its large angle with the front of the air conditioner, experiences stronger airflow between the two vanes, causing condensation to easily form on its surface.

[0030] To address the shortcomings of the aforementioned technologies, this application provides an air outlet control method that controls the air guide mechanism to present different postures at extreme air outlet angles and in the middle air outlet range, thereby balancing the air supply distance and wide-angle air supply in the front area while minimizing condensation.

[0031] To make the above-mentioned objectives, features and advantages of this application more apparent and understandable, specific embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0032] Figure 1 This is a schematic diagram of the air conditioner 010 discharging air at the first extreme air outlet angle in an embodiment of this application. Figure 1 As shown, the air conditioner 010 provided in this embodiment is a floor-standing air conditioner, which includes a housing 100, a fan 200, and an air guide mechanism 300. The fan 200 is disposed in the housing 100, specifically a cross-flow fan 200, and its rotation axis is vertically oriented during normal use. The housing 100 has an air outlet 101, and the air guide mechanism 300 is disposed at the air outlet 101 to adjust the air outlet direction. In this embodiment, a flow guide assembly 400 is also disposed between the air guide mechanism 300 and the fan 200. The flow guide assembly 400 includes multiple spaced fins, which makes the airflow passing through the flow guide assembly 400 more uniform and flows towards the front of the air conditioner 010 to the air guide mechanism 300.

[0033] In this embodiment, the air guiding mechanism 300 includes a rotatable first air guiding member 310 and a second air guiding member 320. The first air guiding member 310 includes a first air guiding plate 311, and the second air guiding member 320 includes a second air guiding plate 321. The air guiding mechanism 300 can control the air outlet direction of the air conditioner 010 between a first limit air outlet angle and a second limit air outlet angle by adjusting the deflection angle of the first air guiding plate 311 and the second air guiding plate 321. Specifically, the first air guiding member 310 and the second air guiding member 320 can be driven to rotate by two independent motors. During the air sweeping process, a main air outlet channel 301 can be formed between the first air guiding plate 311 and the second air guiding plate 321. By rotating the first air guiding member 310 and the second air guiding member 320, the shape (open, parallel, or tapered) and orientation of the main air outlet channel 301 can be adjusted.

[0034] In this embodiment, the first air guide 310 further includes a first auxiliary plate 312 parallel to and spaced apart from the first air guide plate 311, and the second air guide 320 further includes a second auxiliary plate 322 parallel to and spaced apart from the second air guide plate 321. The first auxiliary plate 312 is disposed on the side of the first air guide plate 311 facing away from the main air outlet channel 301, and the second auxiliary plate 322 is disposed on the side of the second air guide plate 321 facing away from the main air outlet channel 301. The number of first auxiliary plates 312 and second auxiliary plates 322 can be one or more. When there are multiple first auxiliary plates 312 and multiple second auxiliary plates 322, the multiple first auxiliary plates 312 are arranged in parallel and spaced apart, and the multiple second auxiliary plates 322 are arranged in parallel and spaced apart. An auxiliary air duct can be formed between the first auxiliary plate 312 and the first air guide plate 311, or between adjacent first auxiliary plates 312; similarly, an auxiliary air duct can be formed between the second auxiliary plate 322 and the second air guide plate 321, or between adjacent second auxiliary plates 322. Therefore, by setting the first auxiliary plate 312 and the second auxiliary plate 322, the function of auxiliary flow guidance can be achieved.

[0035] The air outlet control method provided in this application embodiment can be applied to the air conditioner 010 described above. The air outlet control method includes:

[0036] The air guide mechanism 300 is controlled to move according to a preset rule so that the air conditioner 010 sweeps air between the first limit air outlet angle and the second limit air outlet angle.

[0037] When the air conditioner 010 discharges air at the first limit air outlet angle and the second limit air outlet angle, an open main air outlet channel 301 is formed between the first air guide plate 311 and the second air guide plate 321. When the air conditioner 010 discharges air in the middle air outlet section between the first limit air outlet angle and the second limit air outlet angle, the first air guide plate 311 and the second air guide plate 321 are parallel to each other or form a gradually narrowing main air outlet channel 301.

[0038] Figures 2 to 4 This is a schematic diagram of the different postures of the air guide mechanism 300 when the air conditioner 010 is discharging air in the middle air outlet section in the embodiments of this application; Figure 5 This is a schematic diagram of the air conditioner 010 discharging air at the second extreme air outlet angle in an embodiment of this application. Figures 1 to 5 As shown, the air guide mechanism 300 can control the airflow in the left and right directions, and has a left limit position and a right limit position. In this embodiment, the first limit air outlet angle corresponds to the left limit position of the air guide mechanism 300, and the second limit air outlet angle corresponds to the right limit position of the air guide mechanism 300, as examples. It should be understood that in this embodiment, the open main air outlet channel 301 means that the width of the end of the main air outlet channel 301 near the inside of the air conditioner 010 is smaller than the width of the end near the outside of the air conditioner 010, and the narrowing main air outlet channel 301 means that the width of the end of the main air outlet channel 301 near the inside of the air conditioner 010 is larger than the width of the end near the outside of the air conditioner 010.

[0039] exist Figure 1 and Figure 5 In the middle, the main air outlet duct 301 between the first air guide plate 311 and the second air guide plate 321 is open to the outside, while... Figure 2 , Figure 3 and Figure 4 Although the main air outlet duct 301 faces different directions, the first air guide plate 311 and the second air guide plate 321 remain parallel. It should be understood that the first air guide plate 311 and the second air guide plate 321 being parallel to each other means being roughly parallel, and there can be a small angle of inclination (e.g., within 5°); in other embodiments, the first air guide plate 311 and the second air guide plate 321 can also form a tapering main air outlet duct 301 to enhance the air outlet speed and increase the air delivery distance.

[0040] The air outlet control method of this application ensures that when the air guide mechanism 300 is at the two extreme positions of the sweeping path, an open main air outlet channel 301 is formed between the first air guide plate 311 and the second air guide plate 321, which is beneficial for the air conditioner 010 to sweep air over a wider range. Alternatively, to achieve a wider range of air outlet angles, it is not necessary for both the first air guide plate 310 and the second air guide plate 320 to deflect at large angles at their extreme positions; only one of them needs to deflect at a large angle. For example, when the air conditioner 010 is discharging air at the first extreme air outlet angle, the deflection angle of the second air guide plate 320 does not need to be too large; when the air conditioner 010 is discharging air at the second extreme air outlet angle, the deflection angle of the first air guide plate 310 does not need to be too large. Since users are generally located more in front of the air conditioner 010, when the air conditioner 010 discharges air in the central air outlet section, the first air guide plate 311 and the second air guide plate 321 are parallel to each other or form a contracting main air outlet channel 301, which helps to increase the air delivery distance and improve the user experience for users directly in front of the air conditioner 010. Therefore, the air outlet control method of this application enables the air conditioner 010 to have a wider sweep angle and can increase the air delivery distance in the area directly in front of the air conditioner 010, thereby improving the user experience.

[0041] Furthermore, in this embodiment, when the air conditioner 010 discharges air at the first and second extreme air discharge angles, an open main air discharge channel 301 is formed between the first air guide plate 311 and the second air guide plate 321, which also helps to avoid condensation on the first air guide plate 310 and the second air guide plate 320. Taking the air conditioner 010 discharging air at the first extreme air discharge angle as an example, if the main air discharge channel 301 is not open, then while ensuring that the sweeping angle range remains unchanged, the second air guide plate 321 should be further deflected to the left. At this time, the intensity of the airflow in the main air discharge channel 301 sweeping the second air guide plate 321 is increased, and condensation is more likely to occur on the second air guide plate 321 under cooling conditions. In contrast, in this embodiment, under the first extreme air outlet angle, the second air guide plate 321 will not deflect to the left by too large an angle, which makes the angle between the second air guide plate 321 and the front direction of the air conditioner 010 smaller. The intensity of the second air guide plate 321 being swept by the airflow in the main air outlet channel 301 is reduced, so it is relatively less likely to produce condensation.

[0042] Furthermore, when the air conditioner 010 discharges air at the first and / or second extreme air outlet angles, the first air guide plate 311 and the second air guide plate 321 form an angle of 30° to 60°. By controlling the angle between the first air guide plate 311 and the second air guide plate 321 to 30° to 60°, the airflow from the air conditioner 010 at the first and / or second extreme air outlet angles can be dispersed outwards, thereby increasing the air delivery range of the air conditioner 010. It can be understood that the larger the angle between the first air guide plate 311 and the second air guide plate 321, the more beneficial it is for wide-angle air delivery, but at the same time, the air delivery distance is shortened. Therefore, when discharging air at the first and / or second extreme air outlet angles, the angle between the first air guide plate 311 and the second air guide plate 321 is 30° to 60°, which allows users in front of the air conditioner 010 to also have a better user experience. Furthermore, at the extreme air outlet angle, the first air guide plate 311 and the second air guide plate 321 form an angle of 30° to 60°, which makes it less likely for condensation to form on the first air guide plate 311 and the second air guide plate 321. Optionally, in this embodiment, when the air conditioner 010 is discharging air at the first extreme air outlet angle and / or the second extreme air outlet angle, the first air guide plate 311 and the second air guide plate 321 form an angle of 40°.

[0043] In this embodiment, the rotation axes of the first air guide 310 and the second air guide 320 (points A1 and A2 in the figure, respectively) are parallel to each other and symmetrically arranged with respect to the central symmetry plane (represented by the dashed line M in the figure). The rotation axes of the first air guide 310 and the second air guide 320 are located on the first side 102 (left side in the figure) and the second side 103 (right side in the figure) of the central symmetry plane M, respectively. When the air conditioner 010 discharges air at the first extreme air outlet angle, the air outlet direction is towards the first side 102 of the central symmetry plane M. When the air conditioner 010 discharges air at the second extreme air outlet angle, the air outlet direction is towards the second side 103 of the central symmetry plane M. The air guide mechanism 300 is in the first air outlet direction at the first extreme air outlet angle ( Figure 1 (Hollow arrow) and the second air outlet direction at the second extreme air outlet angle ( Figure 5 The hollow arrowhead is symmetrical with respect to the central symmetry plane M. The air outlet direction of the air guide mechanism 300 refers to the midpoint of the width of the downstream end of the main air outlet channel 301 (e.g., ...). Figure 1 , Figure 5 The airflow direction at point A3, that is, the midpoint of the line connecting the ends of the first air guide plate 311 and the second air guide plate 321 near the outside of the air conditioner 010 (e.g., point A3). Figure 1 , Figure 5The airflow direction at point A3. In this embodiment, the central symmetry plane M is a defined virtual plane that is parallel to the front direction of the air conditioner 010 and parallel to the rotation axis of the first air guide 310 and the second air guide 320, so that the overall air volume on both sides in front of the air conditioner 010 is approximately the same during a period of air sweeping, and the flow field is approximately symmetrical at the first limit air outlet angle and the second limit air outlet angle.

[0044] In this embodiment, when the air conditioner 010 discharges air at the first extreme air outlet angle, the first air guide plate 311 forms an angle of 50° to 70° with the central symmetry plane M, and the second air guide plate 321 forms an angle of 30° to 30° with the central symmetry plane M. Furthermore, the ends of both the first air guide plate 311 and the second air guide plate 321 near the outside of the air conditioner 010 are deflected toward the first side 102 of the central symmetry plane M. When the air conditioner 010 discharges air at the second extreme air outlet angle, the second air guide plate 321 forms an angle of 50° to 70° with the central symmetry plane M, and the first air guide plate 311 forms an angle of 10° to 30° with the central symmetry plane M. Furthermore, the ends of both the first air guide plate 311 and the second air guide plate 321 near the outside of the air conditioner 010 are deflected toward the second side 103 of the central symmetry plane M. Optionally, when the air conditioner 010 is discharging air at the first extreme air outlet angle, the first air guide plate 311 forms a 60° angle with the central symmetry plane M, and the second air guide plate 321 forms a 20° angle with the central symmetry plane M; when the air conditioner 010 is discharging air at the second extreme air outlet angle, the second air guide plate 321 forms a 60° angle with the central symmetry plane M, and the first air guide plate 311 forms a 20° angle with the central symmetry plane M. This achieves a 40° angle between the first air guide plate 311 and the second air guide plate 321 at both the first and second extreme air outlet angles, resulting in a total air delivery angle range of 120°. Therefore, wide-angle air delivery is achieved, while maintaining a certain air delivery distance even at extreme positions. Simultaneously, this configuration makes it less likely for condensation to form on the second air guide plate 321 when the air conditioner 010 is discharging air at the first extreme air outlet angle, and less likely for condensation to form on the first air guide plate 311 when the air conditioner 010 is discharging air at the second extreme air outlet angle.

[0045] In one embodiment, the preset rules for the movement of the air guide mechanism 300 include:

[0046] During the process of the air outlet direction of the air conditioner 010 changing from the first extreme air outlet angle to the middle air outlet range, the first air outlet component 310 is controlled to rotate while keeping the second air guide component 320 stationary, so that the first air guide plate 311 and the second air guide plate 321 are parallel to each other or form a contracting main air outlet channel 301 (this process corresponds to...). Figures 1 to 2 (State); During the process of the air conditioner 010 discharging air in the middle air outlet section, the first air guide 310 and the second air guide 320 are controlled to rotate simultaneously (this process corresponds to...) Figures 2 to 4(State); During the process of the air outlet direction of the air conditioner 010 changing from the middle air outlet section to the second extreme air outlet angle, the rotation of the first air guide 310 is stopped first, and the second air guide 320 is controlled to continue rotating, so that an open main air outlet channel 301 is formed between the first air guide plate 311 and the second air guide plate 321 (this process corresponds to) Figures 4 to 5 (The state). The process of switching from the second limit air outlet angle to the first limit air outlet angle is the reverse of the control steps described above, and will not be repeated here.

[0047] In another embodiment, the preset rules for the movement of the air guide mechanism 300 include:

[0048] During the process of the air outlet direction of the air conditioner 010 changing from the first extreme air outlet angle to the middle air outlet range, the first air guide 310 and the second air guide 320 are controlled to rotate simultaneously, and the rotation speed of the first air guide 310 is greater than that of the second air guide 320, so that the first air guide plate 311 and the second air guide plate 321 are parallel to each other or form a contracting main air outlet channel 301 (this process corresponds to...). Figures 1 to 2 (State); During the process of the air conditioner 010 discharging air in the middle air outlet section, the first air guide 310 and the second air guide 320 are controlled to rotate simultaneously at the same speed (this process corresponds to) Figures 2 to 4 (State); During the process of the air outlet direction of the air conditioner 010 changing from the middle air outlet section to the second extreme air outlet angle, the first air guide 310 and the second air guide 320 are controlled to rotate simultaneously, and the rotation speed of the second air guide 320 is greater than the rotation speed of the first air guide 310, so that an open main air outlet channel 301 is formed between the first air guide plate 311 and the second air guide plate 321 (this process corresponds to) Figures 4 to 5 (The state). The process of switching from the second limit air outlet angle to the first limit air outlet angle is the reverse of the control steps described above, and will not be repeated here.

[0049] By controlling the air guide mechanism 300 using the above two preset rules, the air guide mechanism 300 can form an open main air outlet channel 301 at the first and second limit air outlet angles, with a slower wind speed and a wider air outlet range; when air is outleted in the middle air outlet section, it forms a parallel or gradually narrowing main air outlet channel 301, resulting in a faster wind speed and a longer air delivery distance.

[0050] Furthermore, the air outlet control method may also include: upon receiving a shutdown command, controlling the air guide mechanism 300 to block the air outlet 101.

[0051] Through the above control method, the air guide mechanism 300 can close the air outlet 101 when the air conditioner 010 is not in use, protecting the internal components of the air conditioner 010 and improving its aesthetics. Furthermore, since the air guide mechanism 300 is used both for air sweeping and for closing the air outlet 101, the structure of the air conditioner 010 can be simplified, reducing the number of components such as the motor.

[0052] In this embodiment, when the air outlet 101 is blocked by the air guide mechanism 300, the first air guide plate 311 and the second air guide plate 321 jointly block the air outlet 101, and the first auxiliary plate 312 and the second auxiliary plate 322 are located inside the air conditioner 010. In this embodiment, by setting the first auxiliary plate 312 and the second auxiliary plate 322, the air outlet 101 can also be assisted in airflow guidance; by using the first air guide plate 311 and the second air guide plate 321 to jointly close the air outlet 101, and by placing the first auxiliary plate 312 and the second auxiliary plate 322 inside the air conditioner 010, the aesthetics of the air conditioner 010 are improved.

[0053] This application embodiment also provides an air outlet control device 610, which is used to: control the air guide mechanism 300 to rotate according to a preset rule so that the air conditioner 010 sweeps air between a first limit air outlet angle and a second limit air outlet angle; wherein, when the air conditioner 010 outlets air at the first limit air outlet angle and the second limit air outlet angle, an open main air outlet channel 301 is formed between the first air guide plate 311 and the second air guide plate 321; when the air conditioner 010 outlets air in the middle air outlet section between the first limit air outlet angle and the second limit air outlet angle, the first air guide plate 311 and the second air guide plate 321 are parallel to each other or form a gradually narrowing main air outlet channel 301.

[0054] The specific method and principle of the air outlet control device 610 controlling the air guide mechanism 300 to achieve air sweeping can be referred to the previous introduction of the air outlet control method, and will not be repeated here.
