Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and in particular to a wind shield assembly and an air conditioning indoor unit having the same. Background Art

[0002] Wall-mounted air conditioners are currently widely used due to their compact footprint, flexible installation, energy efficiency, and high cost-effectiveness. Users are increasingly demanding these air conditioners, particularly with regard to air cleanliness. During operation, the cleanliness of the air conditioner's internal components directly impacts the quality of the air it blows. Therefore, improving the cleanliness of the air conditioner's interior is crucial to enhancing the user experience.

[0003] To prevent dust from entering the interior of an air conditioner, which could result in unclean air, manufacturers typically install a drive mechanism and a windshield at the air inlet. When the air conditioner is operating, the drive mechanism drives the windshield to clear the air inlet, allowing air to flow normally. When the air conditioner is not operating, the drive mechanism drives the windshield to block the air inlet, preventing dust from entering the air conditioner. This ensures a clean interior and extends the air conditioner's service life.

[0004] However, although the setting method of the drive device driving the wind shield structure can prevent dust from entering the interior of the air conditioner, when the drive device fails to drive normally due to faults such as magnetic pole damage and poor wire contact, the wind shield structure is likely to always block the air inlet, causing the air conditioner to have abnormal air intake and unable to operate normally, thereby reducing the operating reliability of the air conditioner. Summary of the Invention

[0005] The main purpose of the present invention is to provide a wind shield assembly and an air conditioner indoor unit having the same, so as to solve the problem of poor operating reliability of air conditioners in the prior art.

[0006] In order to achieve the above-mentioned purpose, according to one aspect of the present invention, a windshield assembly is provided, comprising: a windshield structure, which is rotatably arranged at the air inlet of the air-conditioning indoor unit around a predetermined rotation center line to rotate to an open position for opening the air inlet or a closed position for blocking the air inlet; wherein, when the windshield structure is in the closed position, the vertical plane passing through the predetermined rotation center line is used as the vertical reference plane S, and the center of gravity of the windshield structure is located on the side of the vertical reference plane S close to the open position, so that when the windshield structure is not subjected to the external driving force applied thereto, the windshield structure moves to the open position under the action of its gravity.

[0007] Furthermore, the windshield structure includes a first windshield portion and a second windshield portion. When the windshield structure is in a closed position, the first windshield portion is located on a side of the vertical reference plane S close to the open position, and the second windshield portion is located on a side of the vertical reference plane S close to the closed position; wherein the weight G1 of the first windshield portion is greater than the weight G2 of the second windshield portion.

[0008] Furthermore, the windshield structure includes an air inlet baffle, the first airshield part and the second airshield part are two plate sections of the air inlet baffle, and the volume of the first airshield part is larger than the volume of the second airshield part, so that the weight G1 of the first airshield part is larger than the weight G2 of the second airshield part.

[0009] Furthermore, the material density P1 of the first windshield portion is greater than or equal to the material density P2 of the second windshield portion, so that the weight G1 of the first windshield portion is greater than the weight G2 of the second windshield portion.

[0010] Furthermore, the windshield structure includes an air inlet baffle and a weight-increasing member. The first airshield portion and the second airshield portion are two plate sections of the air inlet baffle. The weight-increasing member is arranged on the first airshield portion so that the weight G1 of the first airshield portion is greater than the weight G2 of the second airshield portion.

[0011] Furthermore, the windshield assembly also includes a bearing structure, which is arranged at the air inlet, and the bearing structure has a rotating shaft, and the central axis of the rotating shaft coincides with the predetermined rotation center line. The windshield structure includes: an air inlet baffle and a rotating part that are connected to each other, and the rotating part can be rotatably mounted on the rotating shaft to drive the air inlet baffle to move so that the air inlet baffle opens or closes the air inlet; the first airshield part and the second airshield part are two plate sections of the air inlet baffle; wherein, with the cross section perpendicular to the length direction of the air inlet baffle as the cross section, the area C1 of the cross section of the first airshield part and the area C2 of the cross section of the second airshield part satisfy: C1=2C2.

[0012] Furthermore, a limiting protrusion is provided on the bearing structure. When the wind shielding structure is in the open position, the end face of the limiting protrusion abuts against at least a portion of the outer peripheral surface of the air inlet baffle to limit and stop the air inlet baffle.

[0013] Furthermore, the windshield assembly also includes a driving structure, which is driven and connected to the windshield structure. The driving structure has an initial state and a working state. When the driving structure is in the initial state, the driving structure drives the windshield structure to rotate from an open position to a closed position; when the driving structure is in the working state, the driving structure drives the windshield structure to rotate from a closed position to an open position.

[0014] Furthermore, the driving structure is a motor. During the process of the windshield structure rotating from the closed position to the open position, the windshield structure has a maximum rotation angle A1, and the driving structure has a rotation angle A2. The maximum rotation angle A1 and the rotation angle A2 satisfy: A1+15°≤A2.

[0015] Furthermore, the windshield assembly also includes a supporting structure, which is arranged at the air inlet. There are multiple windshield structures, and the multiple windshield structures are arranged on the supporting structure at intervals along the width direction of the air inlet.

[0016] Furthermore, the windshield assembly also includes a transmission structure, which is connected to multiple windshield structures. The multiple windshield structures are divided into active baffles and driven baffle groups, and the driven baffle group includes multiple windshield structures; wherein the driving structure is driven and connected to the active baffle, and in the process of the driving structure driving the active baffle to rotate, the active baffle drives the driven baffle group to rotate through the transmission structure.

[0017] Furthermore, there are at least two supporting structures, and at least two supporting structures are respectively connected to both ends of the multiple windshield structures; wherein the driving structure is arranged on one of the supporting structures, and an identification structure is arranged at one end of the windshield structure close to the driving structure.

[0018] According to another aspect of the present invention, an air conditioner indoor unit is provided. The air conditioner indoor unit includes the above-mentioned wind shield assembly.

[0019] Furthermore, when the driving structure of the windshield assembly drives the windshield structure of the windshield assembly to rotate to the open position, the driving structure will produce sound, and the air-conditioning indoor unit also includes: a fan, arranged in the accommodating cavity of the shell; a sound detection structure, arranged on the shell, the sound detection structure is used to detect the sound of the driving structure, so as to determine whether the windshield structure is in the open position according to the duration of the sound; a control structure, connected to both the sound detection structure and the fan, so as to adjust the speed and running time of the fan according to the determination result of the sound detection structure.

[0020] Furthermore, the air-conditioning indoor unit also includes an air outlet baffle, which is rotatably arranged at the air outlet of the shell to avoid and block the air outlet; wherein the control structure is connected to the air outlet baffle to adjust the position of the air outlet baffle according to the judgment result of the sound detection structure.

[0021] According to the technical solution of the present invention, the windshield structure of the windshield assembly is rotatably disposed about a predetermined rotational centerline at the air inlet of an air conditioner indoor unit, so as to rotate to an open position for opening the air inlet or a closed position for blocking the air inlet. When the windshield structure is in the closed position, a vertical plane passing through the predetermined rotational centerline serves as a vertical reference plane S, and the center of gravity of the windshield structure is located on the side of the vertical reference plane S that is closer to the open position. This allows the windshield structure to move to the open position under the action of its gravity when it is not subjected to an external driving force. Thus, when the external device driving the windshield structure to open the air inlet fails due to magnetic pole damage, poor electrical contact, or other faults, the windshield structure's center of gravity deviates from the predetermined rotational centerline, allowing the windshield structure to rotate under its own gravity, thereby opening the air inlet and allowing air to flow into the air inlet normally. This avoids the situation in which the air conditioner indoor unit cannot operate normally due to damage to the driving device, thereby ensuring the operational reliability of the air conditioner indoor unit and solving the problem of poor operational reliability of air conditioners in the prior art. At the same time, the wind shield structure can ensure the normal air intake function of the air conditioner indoor unit through the open position, and can block the air inlet through the closed position, preventing external dust from entering the interior of the air conditioner indoor unit, ensuring the cleanliness of the air blowing of the air conditioner indoor unit and ensuring the air blowing quality of the air conditioner indoor unit.

[0039] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0040] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0042] In order to solve the problem of poor operating reliability of air conditioners in the prior art, the present application provides a wind shield assembly and an air conditioner indoor unit having the same.

[0043] like Figures 1 to 5As shown, the windshield structure 20 of the windshield assembly is rotatably disposed about a predetermined rotational centerline at the air inlet 11 of the air conditioner indoor unit, so as to rotate to an open position for opening the air inlet 11 or a closed position for blocking the air inlet 11. When the windshield structure 20 is in the closed position, a vertical plane passing through the predetermined rotational centerline is used as a vertical reference plane S, and the center of gravity of the windshield structure 20 is located on the side of the vertical reference plane S closer to the open position, so that when the windshield structure 20 is not subjected to an external driving force applied thereto, the windshield structure 20 moves to the open position under the action of its own gravity.

[0044] Using the technical solution of this embodiment, the windshield structure 20 of the windshield assembly is rotatably disposed about a predetermined rotational centerline at the air inlet 11 of the air conditioner indoor unit, so as to rotate to an open position for opening the air inlet 11 or a closed position for blocking the air inlet 11. When the windshield structure 20 is in the closed position, a vertical plane passing through the predetermined rotational centerline serves as a vertical reference plane S, and the center of gravity of the windshield structure 20 is located on the side of the vertical reference plane S closer to the open position. This ensures that when the windshield structure 20 is not subjected to an external driving force, it moves to the open position under the action of its own gravity. In this way, when the external device that drives the windshield structure 20 to open the air inlet 11 fails to drive normally due to magnetic pole damage, poor wire contact, etc., the windshield structure 20 deviates from the center of gravity of the predetermined rotation center line, allowing the windshield structure 20 to drive itself to rotate through its own gravity, thereby enabling the windshield structure 20 to open the air inlet 11, allowing the air inlet 11 to normally enter the air, avoiding the situation where the air conditioner indoor unit cannot operate normally due to damage to the driving device, thereby ensuring the operating reliability of the air conditioner indoor unit, and thus solving the problem of poor operating reliability of the air conditioner in the prior art. At the same time, the windshield structure 20 can ensure the normal air intake function of the air conditioner indoor unit by opening the position, and can block the air inlet 11 by closing the position, preventing external dust from entering the interior of the air conditioner indoor unit, ensuring the cleanliness of the air blown by the air conditioner indoor unit, and ensuring the air blown by the air conditioner indoor unit.

[0045] like Figure 1 and Figure 2As shown, the windshield structure 20 includes a first windshield portion 21 and a second windshield portion 22. When the windshield structure 20 is in the closed position, the first windshield portion 21 is located on the side of the vertical reference plane S closer to the open position, and the second windshield portion 22 is located on the side of the vertical reference plane S closer to the closed position. The weight G1 of the first windshield portion 21 is greater than the weight G2 of the second windshield portion 22. Thus, the windshield structure 20 is divided into two parts, the first windshield portion 21 and the second windshield portion 22. Because the weight G1 of the first windshield portion 21 is greater than the weight G2 of the second windshield portion 22, the center of gravity of the windshield structure 20 is located at the first windshield portion 21, thereby deviating from the vertical reference plane S. At the same time, the first windshield portion 21 is located on the side of the vertical reference plane S close to the windshield structure 20 in the open position, further realizing that the center of gravity of the windshield structure 20 is located on the side of the vertical reference plane S close to the windshield structure 20 in the open position, and rotates to the open position by its own gravity, realizing the self-positioning opening of the windshield structure 20.

[0046] Optionally, to ensure that the center of gravity of the windshield structure 20 is located on the side of the vertical reference plane S close to the windshield structure 20 in the open position, when the external device cannot provide driving force, the windshield structure 20 moves to the open position by its own gravity, so that the air inlet 11 is opened. Figure 2 As shown, the windshield structure 20 includes an air inlet baffle 24. The first windshield portion 21 and the second windshield portion 22 are two plate sections of the air inlet baffle 24. The volume of the first windshield portion 21 is larger than the volume of the second windshield portion 22, so that the weight G1 of the first windshield portion 21 is greater than the weight G2 of the second windshield portion 22. In this way, the center of gravity of the windshield structure 20 is located at the first windshield portion 21 due to the volume of the first windshield portion 21 being larger than the volume of the second windshield portion 22, thereby causing the center of gravity of the windshield structure 20 to deviate from the vertical reference plane S.

[0047] Optionally, to ensure that the center of gravity of the windshield structure 20 is located on the side of the vertical reference plane S close to the side of the windshield structure 20 in the open position, when the external device fails to provide driving force, the windshield structure 20 moves to the open position due to its own gravity, thereby opening the air inlet 11. The material density P1 of the first windshield portion 21 is greater than or equal to the material density P2 of the second windshield portion 22, so that the weight G1 of the first windshield portion 21 is greater than the weight G2 of the second windshield portion 22. In this way, by having the density of the first windshield portion 21 greater than P1 or equal to the density P2 of the second windshield portion 22, the center of gravity of the windshield structure 20 is located at the first windshield portion 21, thereby causing the center of gravity of the windshield structure 20 to deviate from the vertical reference plane S.

[0048] Optionally, to ensure that the center of gravity of the windshield structure 20 is located on the side of the vertical reference plane S close to the side of the windshield structure 20 in the open position, so that when the external device fails to provide driving force, the windshield structure 20 moves to the open position under the action of its own weight, thereby opening the air inlet 11, the windshield structure 20 includes an air inlet baffle 24 and a weight-increasing member. The first airshield portion 21 and the second airshield portion 22 are two plate sections of the air inlet baffle 24. The weight-increasing member is provided on the first airshield portion 21 so that the weight G1 of the first airshield portion 21 is greater than the weight G2 of the second airshield portion 22. Thus, by adding the weight-increasing member to the first airshield portion 21, the weight G1 of the first airshield portion 21 is greater than the weight G2 of the second airshield portion 22, thereby positioning the center of gravity of the windshield structure 20 at the first airshield portion 21, thereby causing the center of gravity of the windshield structure 20 to deviate from the vertical reference plane S.

[0049] Specifically, a gravity block may be provided on the first windshield portion 21 , or a plurality of protruding blocks may be provided on the first windshield portion 21 , so that the weight of the first windshield portion 21 is greater than the weight of the second windshield portion 22 .

[0050] like Figures 1 to 4 As shown, the windshield assembly also includes a supporting structure 30, which is positioned at the air inlet 11. The supporting structure 30 has a rotation axis 31, the central axis of which coincides with a predetermined rotational centerline. The windshield structure 20 includes an interconnected air inlet baffle 24 and a rotating portion 23. The rotating portion 23 is rotatably mounted on the rotation axis 31 to drive the air inlet baffle 24 to open or close the air inlet 11. The first and second airshield portions 21 and 22 are two sections of the air inlet baffle 24. The cross-sectional area C1 of the first and second airshield portions 21 and 22, measured perpendicular to the length of the air inlet baffle 24, satisfies the following relationship: C1 = 2C2. Thus, the windshield structure 20 rotates about the rotation axis 31 of the supporting structure 30 via the rotating portion 23, shielding and avoiding the air inlet 11 through the air inlet baffle 24. At the same time, the rotating part 23 only rotates on the rotating shaft 31 without interfering with the center of gravity offset of the wind shield structure 20, so that the area C1 of the air inlet baffle 24 passing through the first baffle part is larger than the area C2 of the second baffle part, thereby realizing that the center of gravity of the air inlet baffle 24 deviates from the vertical reference plane S, and further realizing that the center of gravity of the wind shield structure 20 deviates from the vertical reference plane S.

[0051] In this embodiment, if Figure 2 As shown by the direction of the arc arrow, the direction from the closed position to the open position is the counterclockwise rotation direction around the circumference of the rotation axis 31.

[0052] like Figure 2As shown, a limiting protrusion 50 is provided on the supporting structure 30. When the windshield structure 20 is in the open position, the end surface of the limiting protrusion 50 abuts against at least a portion of the outer circumference of the air inlet baffle 24, thereby limiting and stopping the air inlet baffle 24. Thus, the arrangement of the limiting protrusion 50 limits the maximum rotation angle of the windshield structure 20, preventing the windshield structure 20 from being damaged and unable to rotate normally due to excessive rotation angles. This extends the service life of the windshield structure 20 and ensures the operational reliability of the windshield structure 20, thereby ensuring the air intake reliability of the air inlet 11 and improving the operational reliability of the air conditioner indoor unit.

[0053] like Figure 5 As shown, the windshield assembly also includes a drive structure 40, which is drivably connected to the windshield structure 20. The drive structure 40 has an initial state and a working state. When the drive structure 40 is in the initial state, the drive structure 40 drives the windshield structure 20 to rotate from the open position to the closed position. When the drive structure 40 is in the working state, the drive structure 40 drives the windshield structure 20 to rotate from the closed position to the open position. In this way, the initial state of the drive structure 40 can apply a force opposite to the gravity of the windshield structure 20 to the windshield structure 20, so that the windshield structure 20 can close the air inlet 11. The working state of the drive structure 40 can drive the windshield structure 20 to open the air inlet 11, so that the windshield structure 20 can close and open the air inlet 11, thereby achieving normal air intake of the air conditioner indoor unit and blocking external dust, ensuring the reliability of the operation of the air conditioner indoor unit while also ensuring the cleanliness of the air blowing of the air conditioner indoor unit.

[0054] Specifically, the drive structure 40 is a motor. During the process of rotating the windshield structure 20 from the closed position to the open position, the windshield structure 20 has a maximum rotation angle A1, and the drive structure 40 has a rotation angle A2. The maximum rotation angle A1 and the rotation angle A2 satisfy the following relationship: A1+15°≤A2. In this way, the windshield structure 20 will rotate a certain angle from the closed position to the open position under the action of its own weight to open the air inlet 11. When the drive structure 40 drives the windshield structure 20 to close the air inlet 11 in the closed position, it will need to rotate the same angle in the direction from the open position to the closed position. Therefore, when the drive structure 40 drives the windshield structure 20 to rotate from the closed position to the open position, the drive structure 40 rotates a certain angle more than the windshield structure 20. This angle is the angle that the windshield structure 20 rotates in the direction from the closed position to the open position under the action of its own weight. The proportional relationship between the rotation angle A2 and the maximum rotation angle A1 makes the rotation angle of the windshield structure 20 and the rotation angle of the driving structure 40 more reasonable. While satisfying that the windshield structure 20 can open the air inlet 11 by its own gravity, it can also reduce the energy consumption of the driving structure 40, thereby realizing the energy-saving and environmental protection performance of the air-conditioning indoor unit.

[0055] Specifically, the center of gravity of the windshield structure 20 is offset from the vertical reference plane S. In the absence of any external forces, its gravity overcomes the friction between it and the supporting structure 30, keeping the windshield structure 20 in the open position. Therefore, when the windshield structure 20 is in the closed position, the self-positioning torque of the drive structure 40 is equal to the difference between the gravity moment of the windshield structure 20 and the friction moment.

[0056] In this embodiment, the angle of rotation of the windshield structure 20 due to its own gravity will not completely open the air inlet 11. In the process of driving the windshield structure 20 to rotate from the closed position to the open position, the driving structure 40 can continue to drive the windshield structure 20 to rotate until the windshield structure 20 contacts the limiting protrusion 50. The driving structure 40 can drive the windshield structure 20 to completely open the air inlet 11 and ensure that the windshield structure 20 will not shake, so as to ensure the air intake stability of the air inlet 11.

[0057] like Figure 5 As shown, the windshield assembly also includes a support structure 90, which is arranged at the air inlet 11. There are multiple windshield structures 20, and the multiple windshield structures 20 are arranged on the support structure 90 at intervals along the width direction of the air inlet 11. In this way, the windshield assembly supports the windshield structure 20 through the support structure 90, enhancing the overall rigidity and stability of the windshield assembly, avoiding deformation or displacement of the windshield structure 20, maintaining the effective closing and opening of the air inlet 11, and ensuring the operational reliability of the windshield structure 20. At the same time, the arrangement of multiple windshield structures 20 is not only convenient for maintenance and replacement, but also enables more precise control of the amount and direction of airflow entering the air conditioner indoor unit. At the same time, by adjusting the opening and angle of different windshield structures 20, the air intake volume can be flexibly adjusted according to actual needs, optimizing airflow distribution, and improving the energy efficiency ratio of the air conditioner indoor unit. At the same time, the layout of multiple windshield structures 20 can disperse the aerodynamic noise generated when the airflow passes through the air inlet 11. Through the interaction between adjacent windshield structures 20, the noise generated by the airflow impact of a single windshield structure 20 can be reduced, creating a quieter use environment.

[0058] Specifically, the plurality of wind shielding structures 20 each include an air inlet baffle 24 . When the plurality of wind shielding structures 20 are in the open position, the air inlet baffles 24 of the plurality of wind shielding structures 20 are arranged in parallel.

[0059] like Figure 5As shown, the windshield assembly also includes a transmission structure 100, which is connected to multiple windshield structures 20. The multiple windshield structures 20 are divided into active baffles and passive baffle groups, and the passive baffle group includes multiple windshield structures 20. The drive structure 40 is connected to the active baffles. When the drive structure 40 drives the active baffles to rotate, the active baffles drive the passive baffle group to rotate via the transmission structure 100. In this way, by directly connecting the drive structure 40 to the active baffles and then using the transmission structure 100 to drive multiple passive baffle groups to operate simultaneously, the number of drive components is significantly reduced, reducing control complexity. This allows a single drive structure 40 to efficiently control multiple windshield structures 20, thereby improving the overall operating efficiency of the system. Furthermore, the linkage mechanism between the active baffles and the passive baffle group ensures that all windshield structures 20 operate synchronously under the same command. Whether opening or closing, all baffles respond in unison, enhancing the sealing of the air inlet 11 in the closed state, reducing air leakage, and improving the energy efficiency and operating stability of the air conditioner indoor unit.

[0060] Specifically, the transmission structure 100 is a connecting rod, which is hingedly connected to the air inlet baffles 24 of the plurality of wind shield structures 20 .

[0061] like Figure 5 As shown, there are at least two support structures 90, each connected to each end of the windshield structures 20. The drive structure 40 is mounted on one of the support structures 90, and an identification structure 25 is provided at one end of the windshield structure 20, proximate to the drive structure 40. Thus, the at least two support structures 90, each connected to each end of the windshield structures 20, provide stronger support and guidance, making the windshield structures 20 more stable during opening and closing, reducing the risk of shaking and deformation, enhancing the rigidity of the windshield structures 20, and extending their service life. Furthermore, the positioning of the identification structure 25 facilitates installation, reducing the difficulty and improving efficiency.

[0062] The present application also provides an air-conditioning indoor unit, which includes the above-mentioned wind shield assembly.

[0063] like Figure 1 、 Figure 3 and Figure 4As shown, when the drive structure 40 of the windshield assembly drives the windshield structure 20 of the windshield assembly to rotate to the open position, the drive structure 40 generates a sound. The air conditioner indoor unit also includes a fan 60, a sound detection structure 70, and a control structure. The fan 60 is disposed within the accommodating chamber 12 of the housing 10. The sound detection structure 70 is disposed on the housing 10 and is used to detect the sound of the drive structure 40 to determine whether the windshield structure 20 is in the open position based on the sound. The control structure is connected to both the sound detection structure 70 and the fan 60 to adjust the speed and operating time of the fan 60 based on the determination result of the sound detection structure 70. Thus, when the drive structure 40 normally drives the windshield structure 20 to rotate to open the air inlet 11, the drive structure 40 generates a sound of a normal frequency. The sound detection structure 70 detects the duration of the sound of the drive structure 40. When the duration of the sound of the drive structure 40 meets a preset value, it indicates that the windshield structure 20 has opened the air inlet 11, and the sound detection structure 70 determines that the windshield structure 20 is in the open position. When the sound duration of the driving structure 40 does not meet the preset value, it is determined that the windshield structure 20 is not in the open position, which means that the driving structure 40 is damaged and cannot drive the windshield structure 20 to rotate and open the air inlet 11. The control structure controls the fan 60 to turn on. After the fan 60 rotates, air pressure will be generated in the accommodating cavity 12 of the shell 10. Since the area C1 of the first windshield part 21 of the air inlet baffle 24 is larger than the area C2 of the second windshield part 22, the external air pressure on the first windshield part 21 will be greater than the pressure on the second windshield part 22, so that the air inlet baffle 24 rotates from the closed position to the open position, so that the air inlet 11 is opened, ensuring the normal circulation of airflow, and thus ensuring the normal operation of the air-conditioning indoor unit.

[0064] In this embodiment, the driving structure 40 drives the windshield structure 20 to rotate until it contacts the limiting protrusion 50 to ensure full opening of the air inlet 11. Therefore, the driving structure 40 produces a stalling sound when the windshield structure 20 contacts the limiting protrusion 50. Therefore, the sound detection structure 70 can also determine whether the driving structure 40 is activated and whether the driving structure 40 is damaged by detecting whether the sound produced by the driving structure 40 is a stalling sound.

[0065] Specifically, the control structure controls the fan 60 to run at a speed of 1800 r / min and run at high speed for 30 seconds to ensure that the air pressure inside the shell 10 can generate a pressure difference with the air pressure outside the shell 10 to achieve the rotation of the windshield structure 20.

[0066] In this embodiment, the sound detection structure 70 picks up the sound of the driving structure 40 through a microphone.

[0067] like Figure 4As shown, the air conditioner indoor unit further includes an air outlet baffle 80, which is rotatably disposed at the air outlet 13 of the housing 10 to avoid and block the air outlet 13. A control structure is connected to the air outlet baffle 80 to adjust the position of the air outlet baffle 80 based on the determination result of the sound detection structure 70. Thus, when the sound detection structure 70 determines that the wind shielding structure 20 is not in the open position, the control structure controls the air outlet baffle 80 to open, thereby facilitating the flow of air out through the air outlet 13 when the fan 60 rotates, thereby ensuring the continuity of the air pressure within the accommodating chamber 12.

[0068] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0069] The windshield structure of the windshield assembly is rotatably disposed about a predetermined rotational centerline at the air inlet of the air conditioner indoor unit, so as to rotate to an open position for opening the air inlet or a closed position for blocking the air inlet. When the windshield structure is in the closed position, a vertical plane passing through the predetermined rotational centerline serves as a vertical reference plane S, and the center of gravity of the windshield structure is located on the side of the vertical reference plane S that is closer to the open position. This allows the windshield structure to move to the open position under the action of its gravity when the windshield structure is not subjected to an external driving force applied thereto. Thus, when the external device driving the windshield structure to open the air inlet fails due to magnetic pole damage, poor electrical contact, or other faults, the windshield structure's center of gravity deviates from the predetermined rotational centerline, allowing the windshield structure to rotate under its own gravity, thereby opening the air inlet and allowing air to flow into the air inlet normally. This avoids the situation in which the air conditioner indoor unit cannot operate normally due to damage to the driving device, thereby ensuring the operational reliability of the air conditioner indoor unit and solving the problem of poor operational reliability of air conditioners in the prior art. At the same time, the wind shield structure can ensure the normal air intake function of the air conditioner indoor unit through the open position, and can block the air inlet through the closed position, preventing external dust from entering the interior of the air conditioner indoor unit, ensuring the cleanliness of the air blowing of the air conditioner indoor unit and ensuring the air blowing quality of the air conditioner indoor unit.
