[0014] The control method provided in this disclosure is used for an indoor unit. The indoor unit includes a control panel, a first air inlet, and a second air inlet. The control panel is used to open or close the second air inlet. The control method includes: acquiring the blockage status of the first air inlet, and adjusting the open / closed state of the control panel according to the blockage status. When the first air inlet is blocked, the air intake of the indoor unit decreases, leading to a decrease in the air output of the air conditioner and a reduction in the operating efficiency of the indoor unit. To improve the operating efficiency of the indoor unit, the blockage status of the first air inlet is acquired.

[0046] In some embodiments, combined with Figures 1 to 3As shown, an indoor unit is provided, including: a housing 10, a panel 20, a drive unit 30, an indoor fan 200, and an indoor heat exchanger 300. The housing 10 includes an air inlet 104. The panel 20 is movably connected to the housing 10 and located at the air inlet 104. The drive unit 30 is disposed on the housing 10, and the output shaft of the drive unit 30 is connected to the panel 20 for driving the panel 20 to rotate relative to the housing 10, thereby opening or closing the air inlet 104. When the panel 20 is in the open state, the panel 20 and the housing 10 form an air intake channel 40 communicating with the air inlet 104.

[0047] The housing assembly 1 for an indoor unit provided in this embodiment includes a housing 10, a panel 20, and a drive member 30. A main air inlet 101 is provided at the top of the housing 10. An air inlet 104 is provided on the front side of the housing 10. The panel 20 is disposed at the air inlet 104. The drive member 30 drives the panel 20 to open or close the air inlet 104. When the filter 103 of the main air inlet 101 at the top is blocked, the drive member 30 is controlled to move the panel 20 relative to the housing 10 to open the air inlet 104. Thus, supplemental airflow is achieved through the air inlet 104 located on the front side of the housing 10. In conjunction with... Figure 1 As shown, when the panel 20 is open, an air intake channel 40 is formed between the panel 20 and the housing 10. External air is introduced into the housing 10 through this air intake channel 40, achieving air circulation. By setting the air intake channel 40 with its inlet side located on the top side of the housing 10, away from the air outlet 400 of the housing 10, the problem of air recirculation in related technologies is solved, thereby effectively improving the air circulation effect and enhancing the temperature regulation effect.

[0048] Furthermore, combined Figure 1 and Figure 2 As shown, a main air inlet 101 is provided at the top of the housing 10. A filter mounting bracket 102 is provided at the main air inlet 101 for mounting a filter 103. When the filter 103 at the main air inlet 101 becomes clogged, the amount of air entering the housing 10 decreases, thereby reducing the amount of air exiting the air outlet 400 and thus reducing the effectiveness of indoor temperature regulation. The housing assembly 1 provided in this disclosure has an air inlet 104 on the front side of the housing 10. A panel 20 rotatably connected to the housing 10 is provided for opening or closing the air inlet 104. When the filter 103 at the top main air inlet 101 becomes clogged, the control panel 20 opens the air inlet 104 to supplement the air intake, thereby ensuring the amount of air exiting and improving the efficiency of indoor temperature regulation. Figure 6As shown, when the filter 103 of the main air inlet 101 is not clogged, the control panel 20 is closed. When the panel 20 is open, an air intake channel 40 is formed between the panel 20 and the housing 10, which communicates with the air inlet 104, thereby isolating the air inlet 104 and the air outlet 400, thus improving the return air situation.

[0049] Optional, combined Figure 1 and Figure 4 As shown, panel 20 includes: panel body 201, first baffle 202, and second baffle 203. Panel body 201 is movably connected to housing 10. First baffle 202 is disposed on one side of panel body 201 and connected to housing 10. Second baffle 203 is disposed on the other side of panel body 201 and connected to housing 10. When the driving member 30 drives panel 20 to open air inlet 104, panel body 201, first baffle 202, second baffle 203, and housing 10 form air inlet channel 40.

[0050] In this embodiment, combined with Figure 1 and Figure 4 As shown, by providing a first baffle 202 and a second baffle 203 on both sides of the panel body 201, the panel body 201, the first baffle 202, and the second baffle 203 form a flow channel, which guides the airflow to the air inlet 104. Simultaneously, the first baffle 202 and the second baffle 203 on both sides block the connection between the air outlet 400 and the air inlet 104, thus avoiding the backflow problem in related technologies and improving the heat exchange effect of indoor air. When the filter 103 of the main air inlet 101 at the top of the housing 10 becomes clogged, the control drive 30 drives the panel 20 to move relative to the housing 10, thereby opening the front air inlet 104 of the housing 10. When the panel 20 moves relative to the housing 10, the panel body 201, the first baffle 202, and the second baffle 203 move relative to the housing 10, and the panel body 201, the first baffle 202, and the second baffle 203, together with the housing 10, form an air inlet channel 40. The air inlet 104 on the front side of the housing 10 is connected through the air inlet channel 40 to provide supplemental air to the air conditioner and improve the temperature regulation effect.

[0051] Optional, combined Figure 4 and Figure 5 As shown, both the first baffle 202 and the second baffle 203 are plate-shaped structures. The first baffle 202 and the second baffle 203 are slidably connected to the housing 10. Specifically, during the rotation of the panel body 201 relative to the housing 10 by the driving member 30, the first baffle 202 and the second baffle 203 slide relative to the housing 10.

[0052] In this embodiment, combined with Figure 4 and Figure 5 As shown, the structures of the first baffle 202 and the second baffle 203 utilize plates to create flow channels between the panel body 201 and the plates on both sides. The plates located on both sides of the panel body 201 can block the return air from both sides. Simultaneously, the plate structure enables a sliding connection with the housing 10. When the air inlet 104 is closed, the plate slides into the housing 10. When the air inlet 104 is opened, the plate slides to the outside of the housing 10 to guide indoor air to the air inlet 104 for heat exchange.

[0053] Optional, combined Figure 4 and Figure 5 As shown, both the first baffle 202 and the second baffle 203 are fan-shaped plates. The center of the fan-shaped plate is located on the side where the panel body 201 is rotatably connected to the housing 10, and the arc-shaped edge of the fan-shaped plate is located on the top side of the housing 10. Thus, the flow channel formed by the panel body 201, the first baffle 202, and the second baffle 203 expands outward relative to the housing 10, increasing the flow area at the air inlet end of the air inlet channel 40 and thereby improving the air intake volume.

[0054] Optional, combined Figure 4 As shown, the panel body 201, the first baffle 202, and the second baffle 203 are integrated into one structure. When the air inlet 104 is opened, by making the panel body 201, the first baffle 202, and the second baffle 203 an integrated structure, air leakage problems caused by loose connections of the panels can be avoided, improving the efficiency of air supply. At the same time, the integrated structure increases the strength of the panel 20 and facilitates installation and disassembly.

[0055] Optional, combined Figure 2 As shown, the housing 10 further includes a first socket 106 and a second socket 108. A first baffle 202 is disposed in the first socket 106 and is slidable relative to the first socket 106. A second baffle 203 is disposed in the second socket 108 and is slidable relative to the second socket 108. The first socket 106 and the second socket 108 are located on opposite sides of the air inlet 104.

[0056] In this embodiment, combined with Figure 2As shown, a first insertion hole 106 and a second insertion hole 108 are respectively provided in the areas on both sides of the air inlet 104 on the housing 10. The first insertion hole 106 and the second insertion hole 108 are strip-shaped holes for installing a first baffle 202 and a second baffle 203. The first baffle 202 is inserted into the first insertion hole 106 and can move relative to the first insertion hole 106. The second baffle 203 is inserted into the second insertion hole 108 and can move relative to the second insertion hole 108. Thus, when the drive member 30 drives the panel 20 to rotate, the first baffle 202 and the second baffle 203 move relative to the first insertion hole 106 and the second insertion hole 108 to open or close the air inlet 104.

[0057] Optional, combined Figure 2 As shown, the air inlet 104 is located on the front side wall of the housing 10. The first insertion hole 106 and the second insertion hole 108 are located on both sides of the air inlet 104, close to the side walls of the housing 10. The first baffle 202 and the second baffle 203 are slidably connected to the first insertion hole 106 and the second insertion hole 108, respectively. When the air inlet 104 is closed, the first baffle 202 and the second baffle 203 are retracted into the housing 10, close to the side walls of the housing 10. This improves the compactness of the internal space arrangement of the housing 10. Simultaneously, the large area of ​​the air inlet 104 increases the supplementary air volume, thereby improving the heat exchange efficiency of the air conditioner.

[0058] Optional, combined Figure 3 As shown, the housing 10 also includes a notch 107 and a mounting groove 109. Combined with Figure 4 As shown, panel 20 also includes a rotation support 204. A notch 107 is located on one side of the air inlet 104. A drive member 30 is disposed in the mounting groove 109. The rotation support 204 is disposed in the notch 107 and is movable relative to the notch 107. The output shaft of the drive member 30 is connected to the rotation support 204 to drive panel 20 to rotate relative to housing 10.

[0059] In this embodiment, combined with Figure 3 As shown, the housing 10 has a notch 107 on one side of the air inlet 104. The rotation support 204 of the panel 20 is mounted on the notch 107, and the rotation support 204 can move relative to the notch 107. The side wall of the housing 10 is provided with a mounting groove 109, and the drive member 30 is mounted in the mounting groove 109. The output shaft of the drive member 30 is connected to the rotation support 204 so that the drive member 30 drives the panel body 201 to rotate relative to the housing 10, thereby opening or closing the air inlet 104.

[0060] Optional, combined Figure 5As shown, the rotating support 204 includes a support portion 2042 and a connecting portion 2044. The support portion 2042 is movably connected to the notch 107. The connecting portion 2044 is disposed on the support portion 2042. The output shaft of the drive member 30 is connected to the connecting portion 2044. The connecting portion 2044 is disposed on the side of the support portion 2042 facing the drive member 30. By controlling the drive member 30 to drive the panel 20 to move relative to the housing 10, air is supplied to the air conditioner, improving the temperature regulation effect.

[0061] Optionally, the number of notches is two, with the two notches spaced apart on the shell 10.

[0062] Optionally, two swivel supports are also provided. The two swivel supports are spaced apart on the side where the panel 20 is swivelly connected to the housing 10.

[0063] In this embodiment, two notches and two rotation supports are provided to improve the installation stability of the panel 20 and the housing 10.

[0064] Optionally, there are two drive units. There are also two mounting slots. The two mounting slots are located on both sides of the air inlet 104 and inside the housing 10. The two mounting slots are respectively set on the opposite side walls of the housing 10. By providing two drive units, the stability of the control panel 20 operation is improved.

[0065] Optionally, the drive unit 30 includes a stepper motor. By using a stepper motor, the opening angle of the panel 20 can be controlled. By controlling the number of steps of the stepper motor, the opening angle of the panel 20 can be adjusted, thereby meeting different air intake requirements.

[0066] Optional, combined Figure 8 As shown, the housing assembly 1 also includes a folded filter 110. One end of the folded filter 110 is connected to the housing 10, and the other end of the folded filter 110 is connected to the panel 20. During the rotation of the panel 20 relative to the housing 10, the drive member 30 causes the folded filter 110 to unfold or fold.

[0067] In this embodiment, combined with Figure 9 As shown, when the filter 103 becomes clogged at the main air inlet 101 at the top of the housing 10, the control drive unit 30 drives the panel 20 to move relative to the housing 10, causing the folded filter 110 to unfold, thereby filtering the air entering the air intake duct 40 and preventing dust and other substances from entering the air conditioner. Combined with... Figure 6 and Figure 7 As shown, when the air inlet 104 is closed, the folded filter 110 can be folded to close the air inlet 104. In this way, by setting the folded filter 110, it can adapt to the switching between two scenarios: the air inlet 104 is open and the air inlet 104 is closed.

[0068] Optional, combined Figure 2 and Figure 8 As shown, the housing 10 also includes a fixing groove 105, which is located on one side of the air inlet 104. The air inlet 104 includes a first side, a second side, a third side, and a fourth side. The first and second sides are opposite to each other. The third and fourth sides are opposite to each other. The panel body 201 is rotatably connected to the first side. The fixing groove 105 is formed on one side of the housing 10 on the second side. The first baffle 202 and the second baffle 203 are movably connected to the housing 10 located on the third and fourth sides. One end of the folded filter 110 is disposed in the fixing groove 105. The other end of the folded filter 110 is connected to the end of the panel body 201 away from the first side. By providing the fixing groove 105, the folded filter 110 can be stored in the fixing groove 105 when folded, so that the panel body 201 can fit snugly against the surface of the housing 10, improving the aesthetic appearance.

[0069] Optionally, the depth of the fixing groove 105 is greater than or equal to the thickness of the folded filter 110 in its folded state. This allows the folded filter 110 to be housed in the fixing groove 105 when folded, enabling the panel body 201 to fit snugly against the surface of the housing 10, improving the aesthetics. Furthermore, by housing the folded filter 110 in the fixing groove 105, dust is prevented from falling into the exposed filter 103, extending the cleaning cycle of the folded filter 110. In some embodiments, an air conditioner is provided, including: the indoor unit 100 of any of the above embodiments.

[0070] In some embodiments, the control device for an indoor unit includes a processor and a memory storing program instructions, wherein the processor is configured to execute a control method for the indoor unit in the above embodiments when the program instructions are executed.

[0071] Combination Figure 1 , Figure 6 and Figure 9 The indoor unit shown, in some embodiments, combines Figure 10 As shown, a control method for an indoor unit is provided, including:

[0072] S1001, the processor obtains the blockage status of the first air inlet.

[0073] S1002, the processor determines the open / closed status of the control panel based on the blockage state.

[0074] The control method for an indoor unit provided in this disclosure includes: obtaining the blockage status of a first air inlet, and adjusting the opening status of the control panel based on the blockage status. By determining the blockage status of the first air inlet, the opening status of the control panel is adjusted. When the first air inlet is blocked, the air intake of the indoor unit decreases, leading to a decrease in the air output of the air conditioner and a reduction in the operating efficiency of the indoor unit. To improve the operating efficiency of the indoor unit, the control panel is opened to open a second air inlet, supplementing the indoor unit with additional air intake and improving its operating efficiency. When the first air inlet is not blocked, the indoor unit has sufficient air intake, and there is no need to open the control panel for supplemental airflow. By controlling the opening status of the control panel based on the blockage status of the first air inlet, the air intake requirements of the indoor unit are met, improving the accuracy of the control panel opening.

[0075] Combination Figure 1 , Figure 6 and Figure 9 The indoor unit shown, in some embodiments, combines Figure 11 As shown, a control method for an indoor unit is provided, including:

[0076] S1101, the processor obtains the air volume and fan speed of the indoor unit.

[0077] S1102, the processor determines the theoretical air volume corresponding to the rotation speed based on the rotation speed.

[0078] S1103, the processor determines the blockage status based on the output air volume and the theoretical output air volume.

[0079] S1104, the processor determines the control panel's open / closed status based on the blockage state.

[0080] In this embodiment, the processor determines whether the indoor unit's airflow is normal based on the difference between the actual airflow and the theoretical airflow. It then further determines whether the indoor unit's air intake is normal based on the airflow. When the indoor unit's airflow is less than the theoretical airflow, it indicates that the indoor unit's air intake is low, suggesting that the filter at the first air intake is clogged. In this case, the second air intake needs to be opened to provide supplemental air, and the control panel opens the second air intake to provide supplemental air to the indoor unit, improving the air conditioning efficiency. When the indoor unit's airflow equals the theoretical airflow, it indicates that the indoor unit's air intake is normal, meaning the filter at the first air intake is not clogged, and there is no need to open the second air intake for supplemental air.

[0081] Optionally, the on / off state of the processor control panel includes the difference between the processor's calculated theoretical airflow and the airflow volume. When the airflow difference is greater than or equal to a first threshold, the processor control panel opens the second air inlet. When the airflow difference is less than the first threshold, the processor control panel remains closed.

[0082] In this embodiment, the opening angle of the control panel can be adjusted based on the calculated airflow difference. When the airflow difference is greater than or equal to a first threshold, the first air inlet is blocked, and the blockage is relatively severe. In this case, the control panel opens to open the second air inlet, supplementing the airflow into the indoor unit to ensure that the air conditioner's output airflow meets the temperature regulation requirements and improves the air conditioner's efficiency. When the airflow difference is less than the first threshold, it indicates that the blockage of the first air inlet is not severe or has not yet occurred. In this case, the control panel remains closed, and air continues to be drawn in through the first air inlet.

[0083] Optionally, the steps for opening the second air inlet on the processor control panel include: opening the processor control panel to a first preset angle; increasing the opening angle of the processor control panel by the second preset angle when the airflow difference is greater than or equal to a second threshold; and maintaining the current angle of the processor control panel when the airflow difference is less than the second threshold. The second threshold is greater than the first threshold.

[0084] In this embodiment, when the airflow difference is greater than or equal to a first threshold, the control panel is first opened to a first preset angle. Then, the airflow difference between the theoretical airflow and the actual airflow continues to be monitored. The airflow difference is compared with a second threshold to determine whether the blockage at the first air inlet has worsened. When the airflow difference is greater than or equal to the second threshold, it indicates that the blockage has worsened, and the current opening angle of the panel cannot meet the airflow requirement. Therefore, the opening angle of the control panel is further increased, adding a second preset angle on top of the first preset angle to increase the flow area and improve the airflow. When the airflow difference is less than the second threshold, the indoor unit's airflow has reached the theoretical airflow, so the current opening angle of the panel is maintained. Both the first and second preset angles are less than the maximum angle the panel can open.

[0085] Optionally, before the step of increasing the opening angle of the processor control panel by a second preset angle, the control method further includes: the processor acquiring the current angle of the panel. When the current angle is equal to an angle threshold, the processor control panel maintains the current angle and issues a first-level filter clogging warning message. When the current angle is less than the angle threshold, the opening angle of the processor control panel increases by a second preset angle.

[0086] In this embodiment, before further increasing the opening angle of the control panel, the current opening angle of the panel is first obtained to determine whether it has reached the maximum value of the panel opening angle, i.e., the angle threshold. If the panel opening angle has already reached the angle threshold, it means that it cannot be opened further, and if the current air intake is still insufficient, it indicates that the blockage of the first air intake has reached its limit. In this case, a level one blockage warning message is issued to remind the user to clean the filter. If the current angle is less than the angle threshold, i.e., the panel opening angle has not yet reached its maximum, the control panel continues to open to a second preset angle based on the first preset angle to further increase the air intake, thereby improving the air output and the air conditioning efficiency.

[0087] The level 1 clogging warning indicates the most severe filter blockage. At this point, the control panel is already at its maximum angle, but the airflow is still below the theoretical value, requiring the user to clean the filter to maintain normal airflow. The level 2 clogging warning indicates the next most severe filter blockage, also at the maximum control panel angle. The level 3 clogging warning indicates a less severe filter blockage, at which point the control panel is not at its maximum angle.

[0088] Optionally, when the airflow difference is less than the second threshold, the control method further includes: the processor acquiring the current angle of the panel. When the current angle equals the angle threshold, the processor issues a second-level filter clogging warning message. When the current angle is less than the angle threshold, the processor issues a third-level filter clogging warning message.

[0089] In this embodiment, when the airflow difference is less than the second threshold, the current angle of the panel is obtained to determine whether the current opening angle has reached the maximum value of the panel opening angle, i.e., the angle threshold. When the current angle equals the angle threshold, it means that the panel opening angle has reached its maximum. After continuing to run for a period of time, the filter will reach the limit of blockage, seriously affecting the air conditioning efficiency. In this case, a level 2 blockage reminder message is sent to the user, prompting the user to clean the filter in time. When the current angle is less than the angle threshold, it means that the panel opening angle can continue to increase. At this time, a level 3 blockage reminder message needs to be sent to the user, prompting the user to clean the filter. Based on the panel opening angle and airflow difference, different levels of reminder messages are sent to the user to help them intuitively understand the current blockage status of the filter, so as to reasonably arrange the filter cleaning time and improve the user experience.

[0095] S1205, the processor issues a filter cleaning prompt based on the clogging status.

[0096] S1206, in response to the instruction that the filter cleaning is complete, the control panel closes the second air inlet.

[0097] In this embodiment, when the user has finished cleaning the filter, the first air inlet is ready for normal use. Then, according to the filter installation completion indicator, the control panel is closed and the first air inlet operates normally.

[0098] Combination Figure 1 , Figure 6 and Figure 9 The indoor unit shown, in some embodiments, combines Figure 13 As shown, a control method for an indoor unit is provided, including:

[0099] S1301, the processor obtains the air volume V1 of the indoor unit and the fan speed.

[0100] S1302, the processor determines the theoretical air volume V0 corresponding to the rotation speed based on the rotation speed.

[0101] S1303, the processor calculates the air volume difference ΔV between the theoretical air volume V0 and the air volume V1.

[0102] S1304, the processor determines whether the airflow difference ΔV is greater than or equal to the first threshold ΔV0. If the result is yes, proceed to S1305. If the result is no, proceed to S1316.

[0103] S1305, the processor control panel is turned on to the first preset angle.

[0104] S1306, the processor determines whether the airflow difference ΔV is greater than or equal to the second threshold ΔV1. If the result is yes, proceed to S1307. If the result is no, proceed to S1311.

[0105] S1307, The processor obtains the current angle of the panel.

[0106] S1308, the processor determines whether the current angle is less than the angle threshold. If the result is yes, proceed to S1309. If the result is no, proceed to S1310.

[0107] S1309, the opening angle of the processor control panel has been increased to a second preset angle.

[0108] S1310, the processor control panel maintains the current angle and issues a level one warning message for filter clogging.

[0109] S1311, the processor control panel remains at the current angle;

[0110] S1312, The processor obtains the current angle of the panel.

[0111] S1313, the processor determines whether the current angle is less than the angle threshold. If the result is yes, proceed to S1314. If the result is no, proceed to S1315.

[0112] S1314, the processor issues a level three warning message for filter clogging.

[0113] S1315, the processor issues a secondary warning message for filter clogging.

[0114] S1316, the processor control panel remains closed.

[0115] In this embodiment, the processor determines whether the indoor unit's airflow is normal by comparing the actual airflow with the theoretical airflow. The airflow difference is calculated based on the theoretical airflow and the actual airflow. This airflow difference is then used to further determine the blockage status of the indoor unit. When the airflow difference is less than a first threshold, it indicates that the blockage at the first air inlet is not severe or not yet blocked. At this time, the panel remains closed, and the processor continues to monitor the airflow difference between the theoretical airflow and the actual airflow, comparing it to the first threshold.

[0116] When the airflow difference is greater than or equal to the first threshold, the first air inlet becomes blocked, and the blockage is relatively severe. In this case, the control panel is activated to open the second air inlet. First, the control panel is opened to the first preset angle, and then the airflow difference between the theoretical airflow and the actual airflow continues to be monitored. The airflow difference is then compared with the second threshold to determine whether the blockage of the first air inlet has worsened based on the comparison result.

[0117] When the airflow difference is greater than or equal to the second threshold, it indicates that the blockage is worsening and the current opening angle of the panel is insufficient to meet the airflow requirements. First, the current opening angle of the panel is obtained to determine if it has reached its maximum value, i.e., the angle threshold. If the panel has already opened to the angle threshold, it cannot be opened further, and if the current airflow is still insufficient, it means that the blockage at the first air inlet has reached its limit. In this case, a level one blockage warning message is issued to remind the user to clean the filter.

[0118] If the current angle is less than the angle threshold, meaning the panel opening angle is not yet at its maximum, the control panel will continue to open to a second preset angle based on the first preset angle to further increase the air intake, thereby improving the air output and air conditioning efficiency. It will continue to monitor the difference between the theoretical air output and the actual air output, comparing it with the second threshold to adjust the panel angle based on the comparison result and send a congestion status alert.

[0119] When the airflow difference is less than the second threshold, the indoor unit's airflow has reached the theoretical airflow, so it is only necessary to maintain the current opening angle of the panel. Then, continue to monitor the theoretical airflow and the airflow difference between the theoretical airflow and the actual airflow, and continue to compare it with the second threshold.

[0120] Furthermore, when the airflow difference is less than the second threshold, the current angle of the panel is obtained to determine whether the current opening angle has reached the maximum value of the panel opening angle, i.e., the angle threshold. When the current angle equals the angle threshold, it means that the panel opening angle has reached its maximum. After continuing to run for a period of time, the filter will reach the limit of blockage, seriously affecting the efficiency of the air conditioner. In this case, a second-level blockage reminder message is sent to the user, prompting the user to clean the filter in time.

[0121] When the current angle is less than the angle threshold, it means that the opening angle of the panel can continue to increase. At this time, a level 3 clogging prompt message needs to be sent to the user to remind the user to clean the filter.

[0122] Based on the opening angle of the panel and the airflow difference, different levels of prompts are sent to the user so that the user can intuitively understand the current clogging status of the filter, so as to reasonably arrange the filter cleaning time and improve the user experience.

[0123] Optionally, the first preset angle can be between 10° and 20°. Specific values ​​for the first preset angle include 10°, 15°, and 20°.
