Description

[0002] With the improvement of living standards, more and more air conditioners are appearing in homes and offices, and almost every household uses air conditioners. As we all know, air conditioners will inevitably accumulate a lot of dust and debris after long-term use, especially in the air duct areas such as the air inlet and outlet.

[0003] The air vent has a complex structure due to the presence of components such as air guides, filters, and panels. If the air conditioner needs cleaning after prolonged use, users can easily open it by rotating the panel and remove the filter by pulling it out. However, removing the air guide requires forcibly removing it by utilizing its deformation. Users are often hesitant to use force for fear of damaging the components, making the removal and installation of the air guide difficult. This makes it challenging to thoroughly clean the air vent, potentially impacting user health. Summary of the Invention

[0043] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0044] The following disclosure provides numerous different embodiments or examples for implementing various structures of this application. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0045] For ease of description, spatial relative terms may be used in the text to describe the relative position or movement of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "front," "back," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure undergoes a positional flip, orientation change, or change of motion, these directional indications will change accordingly. For instance, an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0046] In existing technologies, air conditioners inevitably accumulate a lot of dust and debris after prolonged use, especially in the air duct areas such as the air inlet and outlet. The air vents have a complex structure due to the presence of components such as air guides, filters, and panels. When the air conditioner needs to be disassembled for cleaning after extended use, users can easily open the panel by turning it and remove the filter by pulling it out. However, disassembling the air guide requires using its deformation to forcibly remove it. Users are often hesitant to use force for fear of damaging the components, making the disassembly and installation of the air guide difficult. This makes it difficult to thoroughly clean the air conditioner outlet, potentially affecting user health. Secondly, in existing air guiding devices, the air guide plate is positioned at its initial angle by a limiting structure set on the air conditioner body. During the operation of the air conditioner, all the operating procedures of the air guide plate are calculated based on the initial angle. If the air guide plate is disassembled or bent by human intervention, or if the motor experiences abnormal jamming or abnormal deflection during operation, the initial angle of the air guide plate will deviate, resulting in inaccurate air delivery angle. Only by turning the air conditioner off and on again can the air guide plate be restored to the correct position.

[0047] To address the technical problem that the disassembly and assembly of existing air guide plates are difficult, making it hard to thoroughly clean the air conditioner vents and affecting user health, this application provides an air guide device, an air conditioner, and a control method thereof. The air guide plate can be quickly disassembled and assembled using the magnetic attraction between the first adsorption component and the first ring. At the same time, the angle of the air guide plate relative to the air conditioner body can be obtained in real time to achieve precise air delivery by the air guide plate.

[0048] Figure 1 and Figure 2 An air guiding device 1 provided in this application embodiment is disposed on an air conditioner body 2. The air guiding device 1 includes an air guiding plate 11, a first rolling assembly 12, and an angle monitoring assembly 13. The air guiding plate 11 is detachably connected to the air conditioner body 2, and a first adsorption member 111 is disposed on the side of the air guiding plate 11 facing the air conditioner body 2. The first rolling assembly 12 includes a first collar 121 rotatably disposed on the air conditioner body 2, and the first collar 121 is configured to have a magnetic attraction force to attract the first adsorption member 111. The angle monitoring assembly 13 is disposed on the air conditioner body 2 and is configured to obtain a first angle of the air guiding plate 11 relative to the air conditioner body 2. When there is a difference between the first angle of the air guiding plate 11 and the target angle, the first collar 121 is controlled to drive the air guiding plate 11 to rotate relative to the air conditioner body 2 through the first adsorption member 111 so that the air guiding plate 11 reaches the target angle.

[0049] Understandably, during installation, the air guide plate 11 is installed by placing the side of the air guide plate 11 with the first suction member 111 facing the air conditioner body 2, bringing the first suction member 111 close to the first collar 121, and utilizing the magnetic attraction between the first suction member 111 and the first collar 121. When disassembling the air guide plate 11, the user only needs to overcome the magnetic attraction between the first suction member 111 and the first collar 121 to quickly and easily disassemble the air guide plate 11, making the disassembly and assembly process convenient and quick. The angle monitoring component 13 can obtain the angle of the air guide plate 11 relative to the air conditioner body 2 in real time, eliminating the need to use the limiting structure set on the air conditioner body 2 to position the initial angle. This avoids inaccurate air delivery angles caused by deviations in the initial angle of the air guide plate 11, thereby more precisely controlling the rotation angle of the air guide plate 11 and achieving precise air delivery from the air guide plate 11.

[0050] In existing air guiding devices, the air guide plate is directly connected to the motor shaft, and the motor directly drives the air guide plate to rotate. To ensure that the air guide plate can be fully closed after disassembly, cleaning, and reinstallation, the rotation angle of the motor is generally designed to be greater than the rotation angle required for the air guide plate to close. Even after the air guide plate contacts the limiting structure on the air conditioner body and reaches the closed state, the motor may still run for a certain period (rotating independently by a certain angle). Because the air guide plate and the motor shaft are strongly connected, the motor's independent rotation needs to overcome the friction between the air guide plate and the motor shaft, causing the motor to overheat and reducing its lifespan. Simultaneously, the motor may cause the air guide plate to collide with the limiting structure of the air conditioner body, producing abnormal noise. For example, assuming the designed rotation range of the air guide plate relative to the air conditioner body is 120°, and the angle at which the motor drives the air guide plate to rotate when the air conditioner is turned off is 125°, then the motor needs to rotate independently by 5°. If the air guide plate is bent, the independent rotation time of the motor will be significantly increased, and the motor will overheat more severely. Therefore, in this embodiment, the driving component 122 and the air guide plate 11 are designed as a flexible connection, as detailed below.

[0051] In some embodiments, such as Figure 3 and Figure 4As shown, the first rolling assembly 12 further includes a driving member 122, a first roller 123, and a first bushing 124. The driving member 122 is disposed on the air conditioner body 2, and the driving member 122 is connected to the first roller 123 via transmission. The first bushing 124 is disposed on the air conditioner body 2, the first roller 123 is rotatably disposed on the inner circumference of the first bushing 124, and a first collar 121 is sleeved on the outer circumference of the first bushing 124. A first magnetic sheet 1231 that attracts the first collar 121 is disposed on the outer circumference of the first roller 123. Specifically, the driving member 122 can be a motor as in the prior art, and the first roller 123 has a shaft hole at its center that matches the output shaft of the motor. The motor drives the first roller 123 to rotate through the main shaft. The first magnetic sheet 1231 can be configured as an arc-shaped thin sheet and is attached to the outer circumference of the first roller 123. Understandably, the driving component 122 drives the first roller 123 to rotate. Utilizing the magnetic attraction between the first magnetic sheet 1231 and the first collar 121, the first collar 121 rotates accordingly. Since the first collar 121 and the first adsorption component 111 are magnetically attracted and adhered to each other, the air guide plate 11 rotates accordingly. The angle of the air guide plate 11, obtained by the angle monitoring component 13, can be input to the driving component 122, thereby achieving precise control of the rotation angle of the air guide plate 11. The air guide plate 11 and the driving component 122 are flexibly connected. When the air guide plate 11 rotates and abuts against the limiting structure of the air conditioner body 2, the driving component 122 can still continue to rotate without overcoming the friction between the air guide plate 11 and the main shaft of the driving component 122. This avoids the driving component 122 rotating independently and causing overheating, thus improving the service life of the driving component 122. After the drive unit 122 continues to rotate at a certain angle, the magnetic attraction between the first magnetic sheet 1231 and the first collar 121, as well as the magnetic attraction between the first collar 121 and the first adsorption member 111, ensures that the air guide plate 11 remains adsorbed on the air conditioner body 2, preventing the air guide plate 11 from rebounding after closing and ensuring the tightness of the air guide plate 11 closure.

[0052] It should be noted that the main body of the first roller 123 can be made of plastic, preferably polyoxymethylene (POM) resin. POM resin has the characteristics of high hardness, high rigidity and high wear resistance, so that the first roller 123 has a self-lubricating effect and makes its rotation smoother.

[0053] In some embodiments, multiple first magnetic sheets 1231 are provided, spaced apart, and multiple second magnetic sheets 1211 corresponding one-to-one with the first magnetic sheets 1231 are provided on the first collar 121. The purpose of designing the first magnetic sheets 1231 and the second magnetic sheets 1211 in an intermittent arrangement is that when the first roller 123 rotates, the magnetic attraction between the first roller 123 and the first collar 121 changes, thereby driving the first collar 121 to rotate. If the first magnetic sheets 1231 and the second magnetic sheets 1211 are designed as circumferential magnetic sheets, the change in the magnetic attraction between the first roller 123 and the first collar 121 is always consistent when the first roller 123 rotates. Therefore, even if the first roller 123 is rotating, the first collar 121 will not rotate, resulting in the first roller 123 being unable to drive the first collar 121 to rotate, and thus the rotation angle of the air guide plate 11 cannot be controlled. However, the number and spacing angle of the first magnetic sheet 1231 and the second magnetic sheet 1211 need to be designed reasonably. If the number is too dense, the magnetic attraction between the first roller 123 and the first collar 121 will change too quickly, which will also cause the first roller 123 to fail to drive the first collar 121 to rotate. Therefore, in order to ensure precise control of the rotation angle of the air guide plate 11, six first magnetic sheets 1231 are provided in this embodiment, with each first magnetic sheet 1231 spaced 60° apart. Of course, those skilled in the art can adjust the number of first magnetic sheets 1231 according to actual needs.

[0054] In some embodiments, such as Figure 4 As shown, the first bushing 124 is provided with a first limiting rib 1241 along its circumference, and the first limiting rib 1241 abuts against the circumferential sidewall of the first collar 121. The first limiting rib 1241 can limit the displacement of the first collar 121 along its axial direction, thereby ensuring that the first collar 121 rotates stably around the first bushing 124, thereby improving the operational stability of the air guide plate 11 when it rotates.

[0055] In some embodiments, such as Figure 5As shown, the first adsorption member 111 includes a first metal sheet 1111 and a first insulating sheet 1112 spaced apart. The first metal sheet 1111 is attached to the outer peripheral side of the first collar 121, and the first metal sheet 1111 attracts the second magnetic sheet 1211. Specifically, the first insulating sheet 1112 can be made of plastic, preferably polyoxymethylene (POM) resin. Optionally, the first metal sheet 1111 can be arc-shaped, with the radius of curvature of the side of the first metal sheet 1111 facing the first magnetic sheet 1231 being equal to the radius of curvature of the side of the first magnetic sheet 1231 facing away from the first roller 123, so that the first metal sheet 1111 can adhere to the first magnetic sheet 1231. When the first metal piece 1111 on the air guide plate 11 approaches the first magnetic piece 1231, the first collar 121 will rotate under the magnetic force of the first magnetic piece 1231 and the first metal piece 1111, so that the first magnetic piece 1231 just fits against the first metal piece 1111, thereby easily disassembling or installing the air guide plate 11. At the same time, by utilizing the magnetic attraction between the first metal piece 1111 and the second magnetic piece 1211, the air guide plate 11 can rotate with the first collar 121, so that the driving component 122 can accurately control the rotation angle of the air guide plate 11.

[0056] Furthermore, a first support body may be provided on the side of the air guide plate 11 facing the air conditioner body 2. The first support body is provided with a first groove, which is an arc-shaped groove, and the first adsorption member 111 is embedded in the first groove.

[0057] In some embodiments, at least two first metal sheets 1111 are provided, and the two first metal sheets 1111 correspond one-to-one with any two adjacent first magnetic sheets 1231 on the first collar 121. The first adsorption member 111 is provided with two first metal sheets 1111. The more first metal sheets 1111 there are, the greater the magnetic attraction force on the first adsorption member 111, making it relatively easier for the user to install the air guide plate 11. However, if this exceeds a certain limit, the air guide plate 11 will easily slide relative to the first collar 121, i.e., a "skipping" situation will occur. The first adsorption member 111 can easily slide from one first magnetic sheet 1231 to the other, which is detrimental to the operation of the air guide plate 11. Therefore, in order to ensure the stable operation of the air guide plate 11 and facilitate installation, two first metal sheets 1111 are provided in this embodiment.

[0058] In some embodiments, the air guide device 1 further includes a second rolling assembly 14, which includes a second bushing 141 and a second collar 142. The second bushing 141 is disposed on the air conditioner body 2, and the second collar 142 is sleeved on the outer periphery of the second bushing 141. A second adsorption member 112 is disposed on the side of the air guide plate 11 facing the air conditioner body 2. The first adsorption member 111 and the second adsorption member 112 are respectively disposed at both ends of the air guide plate 11. The second collar 142 is configured to have a magnetic attraction force to adsorb the second adsorption member 112. Understandably, the driving component 122 drives the first roller 123 to rotate, utilizing the magnetic attraction between the first magnetic sheet 1231 and the first collar 121, thereby causing the first collar 121 to rotate as well. Since the first collar 121 and the first adsorption component 111 are magnetically attracted and adhered to each other, the air guide plate 11 rotates accordingly. Under the magnetic attraction between the second adsorption component 112 and the second collar 142, the second collar 142 can move with the air guide plate 11. The adsorption components 112 are respectively disposed at both ends of the air guide plate 11. During the rotation of the second sleeve 142 around the second bushing 141, the stability of the air guide plate 11 relative to the air conditioner body 2 can be improved. If the air guide plate 11 needs to be installed, the user can align the two ends of the air guide plate 11 with the first sleeve 121 and the second sleeve 142 respectively. The magnetic attraction between the first sleeve 121 and the first adsorption component 111 and the magnetic attraction between the second sleeve 142 and the second adsorption component 112 can be used to remove or install the air guide plate 11.

[0059] The second ring 142 is provided with a third magnetic sheet 1421, and the second adsorption member 112 includes a second metal sheet 1121 that attracts the third magnetic sheet 1421. Specifically, the third magnetic sheet 1421 can be configured as a semi-circular arc, and the second metal sheet 1121 can be configured as a corresponding semi-circular arc that fits against the third magnetic sheet 1421. When the second metal sheet 1121 on the air guide plate 11 approaches the third magnetic sheet 1421, the second ring 142 will rotate under the magnetic force of the third magnetic sheet 1421 and the second metal sheet 1121, so that the third magnetic sheet 1421 just fits against the second metal sheet 1121, thereby easily removing or installing the air guide plate 11.

[0060] Furthermore, a second support body may be provided on the side of the air guide plate 11 facing the air conditioner body 2. The first support body and the second support body are respectively provided at both ends of the air guide plate 11. The second support body is provided with a second groove, which is an arc-shaped groove. The second adsorption member 112 is embedded in the second groove.

[0061] The second bushing 141 is provided with a second limiting rib 1411 along its circumference, and the second limiting rib 1411 abuts against the circumferential sidewall of the second collar 142. The second limiting rib 1411 can restrict the displacement of the second collar 142 along its axial direction, thereby ensuring that the second collar 142 rotates stably around the second bushing 141, thereby improving the operational stability of the air guide plate 11 when it rotates.

[0062] In some embodiments, such as Figure 6 and Figure 7 As shown, the angle monitoring component 13 includes a positioning member 131 and a limiting clamp 132. The limiting clamp 132 is disposed on the inner sidewall of the second sleeve 142 and is slidably connected to the second bushing 141. The positioning member 131 has a first end and a second end disposed opposite to each other. The first end of the positioning member 131 is rotatably connected to the second bushing 141, and the second end of the positioning member 131 is embedded in the limiting clamp 132. One end of the second bushing 141 is provided with a first sidewall 1412, and an electrical... The second end of the positioning member 131 is provided with a conductive pin 1311 that contacts the resistive sheet 1413; a positive electrode 1414 that does not contact the resistive sheet 1413 is provided on the first sidewall 1412; and a negative electrode 1312 that is electrically connected to the conductive pin 1311 is provided at the first end of the positioning member 131. When an external voltage is input between the positive electrode 1414 and the negative electrode 1312, the positive electrode 1414, the resistive sheet 1413, the conductive pin 1311 and the negative electrode 1312 form a circuit.

[0063] It should be noted that the resistor 1413 can be set to an arc shape. When the second ring 142 rotates with the air guide plate 11, the limiting clamp 132 rotates the second end of the positioning member 131. The second end of the positioning member 131 rotates relative to its first end, causing the conductive pin 1311 to contact the resistor 1413. This forms a circuit between the positive electrode 1414, the resistor 1413, the conductive pin 1311, and the negative electrode 1312. The resistance of the circuit changes depending on the contact position between the conductive pin 1311 and the resistor 1413. By calculating the resistance of the resistor 1413 connected to the circuit, the arc length angle of the resistor 1413 can be calculated. The arc length angle of the resistor 1413 is the rotation angle J of the air guide plate 11 relative to the air conditioner body 2. The angle monitoring component 13 can obtain the angle of the air guide plate 11 relative to the air conditioner body 2 in real time, thereby accurately controlling the rotation angle of the air guide plate 11 and achieving precise air delivery across the entire range of the air guide plate 11 at any angle within the designed rotation range. The specific calculation method for the rotation angle J of the air guide plate 11 relative to the air conditioner body 2 is as follows:

[0064] R = V / I, where V is the external voltage input between the positive electrode 1414 and the negative electrode 1312, and I is the current in the path. V and I are directly monitored by the external motherboard.

[0065]

[0066] Where ε is the conversion coefficient between resistor length and resistance, determined according to the preliminary design; R is the resistance of resistor 1413 connected to the circuit, and D is the diameter of resistor 1413. Using the above formula, the rotation angle J of the air guide plate 11 relative to the air conditioner body 2 can be calculated.

[0067] like Figure 8 and Figure 9 As shown, the first end of the positioning member 131 is provided with a limiting post 1313, and the negative electrode 1312 is disposed on the limiting post 1313. The second bushing 141 is provided with a first limiting groove 1415 that engages with the limiting post 1313. The second end of the positioning member 131 is provided with a magnetic tip 1314 that attracts the third magnetic sheet 1421. The magnetic tip 1314 is embedded in the limiting clamp 132, and the conducting pin 1311 is disposed on the side of the magnetic tip 1314 facing the resistive sheet 1413. There is a magnetic attraction between the magnetic tip 1314 and the third magnetic sheet 1421, so that the magnetic tip 1314 always maintains a relative distance with the resistive sheet 1413, thereby ensuring that the conducting pin 1311 and the resistive sheet 1413 are in contact, and avoiding poor contact between the conducting pin 1311 and the resistive sheet 1413 due to deformation caused by long-term operation. Optionally, the main body of the positioning element 131 may be made of plastic, preferably polyoxymethylene (POM) resin, so that it has a self-lubricating effect and reduces the resistance to movement.

[0068] In some embodiments, such as Figure 6 and Figure 9 As shown, the angle monitoring component 13 also includes a cover plate 133. An opening 1416 is provided at the end of the second bushing 141 away from the first sidewall 1412, and the cover plate 133 covers the opening 1416. A first connecting post 1331 connected to the positive electrode 1414 is provided on the cover plate 133, and a second limiting groove 1332 is provided on the cover plate 133 to engage with the limiting post 1313. A second connecting post 1333 connected to the negative electrode 1312 is provided within the second limiting groove 1332. Specifically, one end of the first connecting post 1331 extends into the second bushing 141 and connects to the positive electrode 1414, while the other end has a positive connection terminal for connecting to an external voltage. One end of the second connecting post 1333 extends into the second bushing 141 and connects to the negative electrode 1312, while the other end has a negative connection terminal for connecting to an external voltage. An external voltage can be connected through the positive and negative connection terminals to achieve real-time monitoring of the rotation angle of the air guide plate 11. The first limiting groove 1415 and the second limiting groove 1332 can jointly limit the displacement of the first end of the positioning member 131 in its axial direction, ensuring that the conductive pin 1311 of the positioning member 131 always remains in contact with the resistor piece 1413.

[0069] The resistor 1413 is arc-shaped, and the center of the resistor 1413 is consistent with the rotation center of the air guide plate 11, so that the arc length angle of the resistor 1413 connected to the passage can accurately characterize the rotation angle of the air guide plate 11.

[0070] In some embodiments, such as Figure 9 As shown, the second bushing 141 has a through groove 1417 along its circumference. The limiting clamp 132 includes a clamp body 1321 and a bracket 1322. One end of the bracket 1322 is connected to the clamp body 1321, and the other end is connected to the second collar 142 through the through groove 1417. Specifically, the magnetic tip 1314 can be configured as a wedge shape, and the clamp body 1321 is correspondingly configured as a V-shape, so that the magnetic tip 1314 can be better fitted into the clamp body 1321. The through groove 1417 is arc-shaped. When the positioning member 131 rotates with the air guide plate 11, the bracket 1322 slides along the through groove 1417, which can improve the stability of the second end of the positioning member 131 rotating around the limiting post 1313.

[0071] Optionally, two brackets 1322 are provided to improve the structural strength of the limiting clamp 132, and two through slots 1417 are provided, with each through slot 1417 corresponding to a bracket 1322 and the two being slidably connected.

[0072] In some embodiments, such as Figure 1 and Figure 3 As shown, it also includes a third rolling assembly 15, which includes a third bushing 151 and a third collar 152 rotatably disposed on the outer periphery of the third bushing 151. A third adsorption member 113 is disposed on the side of the air guide plate 11 facing the air conditioner body 2. The third adsorption member 113 is located between the first adsorption member 111 and the second adsorption member 112. The third collar 152 is configured to have a magnetic attraction force to attract the third adsorption member 113. Specifically, a fourth magnetic sheet 1521 may be disposed on the outer periphery of the third collar 152. The fourth magnetic sheet 1521 is semi-circular. The third adsorption member 113 includes a third metal sheet that attracts the fourth magnetic sheet 1521. The third metal sheet may be correspondingly configured to be semi-circular and fit against the fourth magnetic sheet 1521. When the third metal piece on the air guide plate 11 approaches the fourth magnetic piece 1521, the third collar 152 rotates under the magnetic force of the fourth magnetic piece 1521 and the third metal piece, so that the fourth magnetic piece 1521 just fits against the third metal piece, thereby easily disassembling or installing the air guide plate 11, while improving the stability of the air guide plate 11 installation.

[0073] like Figure 1 As shown, this application embodiment provides an air conditioner 100, including an air conditioner body 2 and an air guide device 1 as described above, the air guide device 1 being disposed on the air conditioner body 2.

[0074] This air conditioner 100 embodiment includes all the technical solutions of all the above-mentioned air guide device 1 embodiments, and its working principle and the technical effect achieved are exactly the same, so it will not be described again here.

[0075] The existing air guide device 1 uses an initial angle as a reference and switches between several preset air delivery angles. This means that the air can only be adjusted within a few preset angles and cannot deliver air to specific angles. Therefore, this embodiment optimizes the air delivery control of the air guide plate 11, with the specific control strategy as follows.

[0076] like Figure 10 As shown, an air conditioner 100 control method provided in this application embodiment is applied to the air conditioner 100 as described above, and includes the following steps:

[0077] S1. Obtain the first signal of the air conditioner 100 and the first angle J of the air guide plate 11 relative to the air conditioner body 2. The first signal includes the swing mode and the positioning mode. Specifically, after the air conditioner 100 is turned on, an external voltage is connected between the positive motor and the negative electrode 1312 to obtain the current rotation angle of the air guide plate 11 relative to the air conditioner body 2. If the air guide plate 11 is not manually moved, it should be in the closed state initially. At this time, the first angle of the air guide plate 11 can be calculated to be 0°. Then, the air guide plate 11 is controlled according to the first signal after the air conditioner is turned on.

[0078] S2. If the first signal is in positioning mode, and the first angle J of the air guide plate 11 is equal to the target angle J g When a difference exists, the first ring 121 is controlled to rotate the air guide plate 11 relative to the air conditioner body 2, so that the air guide plate 11 reaches the target angle. For ease of explanation and understanding, it is assumed here that clockwise rotation decreases the angle of the air guide plate 11 and counterclockwise rotation increases the angle of the air guide plate 11. If J g -J > 0 indicates that the current angle of the air guide plate 11 is insufficient and needs to be increased. Therefore, the drive component 122 needs to control the air guide plate 11 to rotate counterclockwise so that the air guide plate 11 reaches the target angle; if J g -J < 0 indicates that the current angle of the air guide plate 11 exceeds the target angle, therefore the drive unit 122 needs to control the air guide plate 11 to rotate clockwise so that the air guide plate 11 reaches the target angle; if J g -J=0 indicates that the air guide plate 11 has reached the target angle, so the air guide plate 11 does not need to rotate and can maintain the current angle.

[0079] Through the above control strategy, the air guide plate 11 can be adjusted at any angle within the designed rotation range to achieve precise air delivery throughout the entire area.

[0080] In some embodiments, the following steps are also included:

[0081] If the first signal is in the air-sweeping mode, and the first angle of the air guide plate 11 is greater than the first angle threshold and the first angle of the air guide plate 11 is less than the second angle threshold, that is, J min <J<J max If the air guide plate 11 continues to rotate, it will continue to rotate; otherwise, it will rotate in the opposite direction. Specifically, J min and J max These are the critical values ​​for the up and down rotation of the air guide plate 11. If the air guide plate 11 does not exceed the critical value, the motor will continue to rotate in the current state. This cycle repeats. If the critical value is exceeded or reached, the air guide plate 11 will reverse, thereby realizing the up and down sweeping of the air guide plate 11.

[0082] In some embodiments, the following steps are also included:

[0083] Obtain the second signal from air conditioner 100;

[0084] If the second signal is in shutdown mode, the air guide plate 11 is controlled to rotate to the initial angle J0, and the drive unit 122 is controlled to continue rotating to the second angle. For example, the second angle can be set to 5°.

[0085] The initial angle, i.e., the closed state of the air guide plate 11 relative to the air conditioner body 2, is 0°. Controlling the air guide plate 11 back to the 0° position, under the limiting structure of the air conditioner body 2, the air guide plate 11 can no longer rotate counterclockwise. However, because the driving component 122 and the first adsorption component 111 are flexibly connected, the driving component 122 can still drive the first roller 123 to continue rotating 5°, causing a 5° misalignment between the first magnetic piece 1231 of the first roller 123 and the second magnetic piece 1211 of the first collar 121. Figure 11 As shown, the air guide plate 11 is always subject to the magnetic attraction between the first ring 121 and the first adsorption member 111, thereby preventing the air guide plate 11 from rebounding and ensuring that the air guide plate 11 is tightly closed relative to the air conditioner body 2.
