Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, and in particular to a regulating component that is simple in structure, responds quickly, and can automatically adjust wind resistance and airflow distribution according to operating conditions, as well as an air outlet and an air conditioner containing the regulating component. Specifically, this invention relates to... Background Technology

[0002] In residential and commercial air conditioning systems, the uniformity of airflow and the stability of air distribution are key factors affecting user experience and energy efficiency. Especially in cooling mode, when the air conditioner operates at low speeds, uneven airflow from the cross-flow fan blades is common, potentially accompanied by condensation on the blade surface. These problems mainly stem from uneven airflow distribution between the blades, which is particularly pronounced in low-temperature, high-humidity environments. Condensation on the fan blade surface not only affects airflow stability but can also lead to increased noise, reduced energy efficiency, and a host of other issues.

[0003] In existing technologies, air conditioner vent structures mostly employ fixed designs or simple mechanical oscillation mechanisms. Fixed structures cannot adapt to airflow changes under different operating conditions, resulting in uneven air distribution at low airflow rates, affecting cooling / heating efficiency. While some solutions using movable air guides can achieve a certain degree of airflow direction adjustment, they are typically complex in structure, have low control precision, insufficient reliability, and cannot achieve adaptive continuous adjustment of the duct cross-section.

[0004] In particular, at low speeds, the fan blades generate less air pressure, making the airflow easily disturbed. Fixed ducts struggle to effectively guide the airflow, potentially creating localized eddies or stagnant zones, resulting in dead zones and impacting overall comfort. Furthermore, traditional sweeping blades operate in a single mode, failing to provide intelligent airflow distribution adjustment and thus failing to meet users' needs for personalized, comfortable airflow.

[0005] Therefore, there is an urgent need in this field for a reasonably structured, rapidly responsive, and precisely controlled regulating component that can be integrated into the air outlet of an air conditioner and automatically adjust the shape of the air duct and the air delivery method according to the actual operating status of the air conditioner (such as mode, speed, temperature, etc.) to achieve a comprehensive effect of optimized air outlet uniformity, anti-water dripping, improved energy efficiency, and enhanced comfort. Summary of the Invention

[0006] The purpose of this invention is to provide an adaptive adjustable component that can automatically adjust the air duct structure, optimize airflow distribution, and improve airflow uniformity and comfort according to the air conditioner's operating status, as well as an air outlet and air conditioner containing the adjustable component, to solve the problems of existing air conditioner air outlet structures being unable to adaptively adjust, uneven airflow at low wind speeds, easy water accumulation, and poor comfort.

[0007] To achieve the above objectives, the present invention provides the following technical solution: The present invention provides an adjustment component applied to the air outlet of an air conditioner, comprising: Two flow guiding units are arranged side by side, each of which includes several flow guiding plates and a drive connection part; All of the aforementioned deflector plates are rotatably mounted on the duct wall; The drive connection part is located on the rear side of the diversion plate and is used to connect with an external linkage mechanism; The flow guide plates of the two flow guide units can be driven uniformly under the linkage mechanism to switch synchronously between the closed state and the unfolded state.

[0008] By using two interconnected and controllable airflow guiding units, all the airflow guiding plates in each unit can move synchronously to form different shapes of airflow duct structures when the airflow guiding plates open or close, thus forming a deformable airflow duct. The structure is simple and reliable, providing a physical basis for realizing adaptive airflow duct adjustment.

[0009] Based on the above technical solution, the present invention can be further improved as follows.

[0010] As a further improvement of the present invention, the windward surface of the deflector plate is an arc-shaped surface, the curvature of which is adapted to the contour of the air duct wall.

[0011] The shape of the airflow guide plate in this invention matches the contour of the air duct, ensuring that the airflow guide plate can smoothly connect with the air duct wall in any state, minimizing airflow separation and eddy current generation, reducing wind resistance and airflow noise, and improving airflow guiding efficiency.

[0012] As a further improvement of the present invention, the linkage mechanism includes a linkage rod that runs through the drive connection portion of all the flow guide plates in the same flow guide unit and a drive assembly that is pulsatorically connected to the linkage rod.

[0013] This invention uses a single linkage rod to achieve mechanical synchronization of all diversion plates, which greatly simplifies the transmission structure, reduces the number of parts, assembly complexity and failure points, and improves the reliability and durability of the entire component.

[0014] As a further improvement of the present invention, in the closed state, all the guide plates in the two guide units come together to form an approximately continuous guide plane; in the unfolded state, a gradually narrowing guide channel is formed between adjacent guide plates in the two guide units.

[0015] The closed state of this invention corresponds to the requirement of large air volume and low wind resistance, while the unfolded state corresponds to the requirement of airflow sorting and concentration. This design allows a single component to flexibly adapt to different operating conditions of the air conditioner.

[0016] As a further improvement of the present invention, the drive assembly includes a motor, a gear is provided on the output shaft of the motor, and a rack is provided at one end of the linkage; the rack is meshed with the gear.

[0017] As a further improvement of the present invention, the driving components in the two flow guiding units are respectively located at both ends of the adjustment component.

[0018] As a further improvement of the present invention, it also includes a hinge block disposed between two adjacent flow guide plates in the two flow guide units.

[0019] The present invention provides an air outlet, comprising: Duct housing; The adjustment component is installed inside the air duct housing; A sweeping blade assembly is installed at the air outlet end of the air duct housing; A drive mechanism is used to drive the sweeping blade assembly to move.

[0020] This invention provides a complete and enhanced air outlet solution, possessing dual capabilities for adjusting both the duct cross-section and the airflow direction, offering a modular platform for comprehensively improving air conditioning performance. This invention employs independent drive units to control the adjustment components and the sweeping blades separately, achieving decoupling and refined control. Both can work independently or in coordination, resulting in clearer control logic and faster, more accurate response.

[0021] As a further improvement of the present invention, the sweeping blade assembly includes a left sweeping blade assembly and a right sweeping blade assembly that can be controlled independently.

[0022] This invention divides the air-sweeping blades into two groups that can be independently controlled, enabling the air outlet to achieve more complex air delivery modes, such as surround air delivery and zoned air delivery, which significantly enhances the flexibility and comfort of air delivery and meets the diverse needs of users.

[0023] The present invention provides an air conditioner comprising: The air outlet; It also includes a cross-flow fan blade, which is disposed inside the air duct housing and located behind the adjustment assembly.

[0024] This invention applies advanced air outlet technology to end products, giving the air conditioner a competitive advantage in terms of uniform airflow, water-proof design, high energy efficiency, and high comfort.

[0025] As a further improvement of the present invention, a control system is also included, the control system being configured to: In heating mode or when high airflow is required, the regulating component is kept in a closed state. In cooling mode, the adjustment component is controlled to be at different deployment angles according to the operating parameters of the cross-flow fan blades.

[0026] This invention intelligently links the working state of the regulating component with the air conditioner's operating mode and the fan's status, achieving fully adaptive duct adjustment without user intervention. It is highly intelligent and can always ensure that the system operates in the optimal or near-optimal duct condition.

[0027] As a further improvement of the present invention, the operating parameters include the current of the motor of the cross-flow fan blade, and the control system is configured as follows: When the current is detected to be continuously lower than the first threshold, the regulating component is controlled to open to the first angle; When the current is detected to be continuously abnormal or fluctuates beyond a preset range, the adjustment component is controlled to open to a second angle greater than the first angle.

[0028] Current is an effective indicator of fan load and airflow status. By judging the air volume and stability through the current threshold and adjusting the angle of the deflector plate in stages, real-time and accurate feedback control of airflow status is achieved, which effectively solves the problem of uneven airflow under low air volume.

[0029] As a further improvement of the present invention, the control system is also configured to control the sweeping blade assembly to switch between parallel air supply mode and surround air supply mode based on the difference between the indoor ambient temperature and the set temperature.

[0030] This invention combines the air-sweeping mode with temperature control logic, so that the air delivery method serves the temperature regulation target: a large air volume direct blowing is used in the rapid temperature adjustment stage, and a comfortable and gentle wrap-around air delivery is used in the stable constant temperature stage, thereby maximizing user comfort while ensuring regulation efficiency.

[0031] As a further improvement of the present invention, the control system is also configured to trigger an alarm if the abnormal operating parameters are still detected after the adjustment component is opened to the maximum angle.

[0032] This invention adds fault diagnosis and user prompt functions, improving product safety and user experience. When adaptive adjustment can no longer correct abnormalities (possibly due to external causes such as filter blockage), timely alarms can guide users to perform maintenance, preventing the equipment from operating in an abnormal state for extended periods.

[0036] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0037] like Figures 1-5 As shown, this invention provides an adjustable duct cross-section component, applied to the air outlet of an air conditioner and positioned downstream of the cross-flow fan blade 300, enabling it to automatically change its shape according to the cooling / heating mode to optimize airflow distribution; specifically, the adjustable component includes: Two flow guiding units are arranged side by side, each flow guiding unit includes several flow guiding plates and a drive connection part; All the deflector plates are rotatably mounted on the duct wall; The drive connection part is located on the rear side of the diversion plate and is used to connect with the external linkage mechanism; The guide plates of the two flow guiding units can be driven uniformly by the linkage mechanism to switch synchronously between the closed and extended states. In the closed state, the guide plates come together to form an approximately continuous flow guiding surface, and the air duct cross-section is at its maximum. In the extended state, the guide plates separate from each other and extend at a predetermined angle, so that the air duct cross-section forms multiple gradually narrowing flow guiding channels.

[0038] By using two interconnected and controllable airflow guiding units, all the airflow guiding plates in each unit can move synchronously to form different shapes of airflow duct structures when the airflow guiding plates open or close, thus forming a deformable airflow duct. The structure is simple and reliable, providing a physical basis for realizing adaptive airflow duct adjustment.

[0039] like Figure 3 As shown, as a further improvement of the present invention, the windward surface of the deflector plate is an arc-shaped surface, the curvature of which is adapted to the contour of the duct wall. That is, the deflector plate has an arc-shaped surface adapted to the contour of the duct, and it is rotatably mounted to the duct wall via a linkage rod; The shape of the airflow guide plate in this invention matches the contour of the air duct, ensuring that the airflow guide plate can smoothly connect with the air duct wall in any state, minimizing airflow separation and eddy current generation, reducing wind resistance and airflow noise, and improving airflow guiding efficiency.

[0040] As a further improvement of the present invention, the linkage mechanism includes a linkage rod that runs through the drive connection portion of all the guide plates in the same flow guiding unit and a drive assembly 3 that is pulsatorically connected to the linkage rod. By adjusting the position of the guide plates through the linkage rod, the wind resistance and airflow direction can be adjusted.

[0041] This invention uses a single linkage rod to achieve mechanical synchronization of all diversion plates, which greatly simplifies the transmission structure, reduces the number of parts, assembly complexity and failure points, and improves the reliability and durability of the entire component.

[0042] like Figures 5-9 As shown, as a further improvement of the present invention, in the closed state, all the guide plates in the two guide units come together to form an approximately continuous guide plane; in the unfolded state, a gradually narrowing guide channel is formed between adjacent guide plates in the two guide units.

[0043] The closed state of this invention corresponds to the requirement of large air volume and low wind resistance, while the unfolded state corresponds to the requirement of airflow sorting and concentration. This design allows a single component to flexibly adapt to different operating conditions of the air conditioner.

[0044] As a further improvement of the present invention, the drive assembly 3 includes a motor 31, a gear 32 is provided on the output shaft of the motor 31, and a rack 33 is provided at one end of the linkage rod; the rack 33 is meshed with the gear 32.

[0045] As a further improvement of the present invention, the driving components 3 in the two flow guiding units are respectively located at both ends of the adjustment component.

[0046] As a further improvement of the present invention, it also includes a hinge block 4 disposed between two adjacent guide plates in the two guide units.

[0047] Specifically, the hinge block 4 is hinged to the air intake plates on both sides. The hinge block 4 can be fixed to the air duct wall. Then the air intake plate is hinged to the hinge block 4, and the rear end is hinged to the linkage rod.

[0048] like Figure 9-13 As shown, the present invention provides an air outlet with the adjusting component, which enables controllable adjustment of air outlet uniformity and direction, comprising: The air duct housing 600 forms an airflow channel, and the adjustment component is installed inside it; The adjustment assembly is installed inside the duct housing 600; The air-sweeping blade assembly 500 is located at the air outlet end of the air duct housing 600, in the final air supply section of the air outlet, and is used to adjust the air supply direction. The drive mechanism is used to drive the sweeping blade assembly 500 to move.

[0049] This invention provides a complete and enhanced air outlet solution, possessing dual capabilities for adjusting both the duct cross-section and the airflow direction, offering a modular platform for comprehensively improving air conditioning performance. This invention employs independent drive units to control the adjustment components and the sweeping blades separately, achieving decoupling and refined control. Both can work independently or in coordination, resulting in clearer control logic and faster, more accurate response.

[0050] As a further improvement of the present invention, the sweeping blade assembly 500 includes a left sweeping blade assembly 700 and a right sweeping blade assembly 800 that can be controlled independently.

[0051] This invention divides the air-sweeping blades into two groups that can be independently controlled, enabling the air outlet to achieve more complex air delivery modes, such as surround air delivery and zoned air delivery, which significantly enhances the flexibility and comfort of air delivery and meets the diverse needs of users.

[0052] The air outlet of this invention significantly improves airflow uniformity: by dynamically controlling the cross-section of the air duct through the adjustment component, it can actively streamline the airflow, eliminate eddies and stagnant zones at low speeds, and ensure uniform and stable airflow delivery, especially enhancing the user experience at low airflow settings. It effectively prevents water buildup on the fan blades: in cooling mode, by adjusting the deflector plate to the extended state, it can concentrate the airflow, increase the wind speed, and reduce the temperature difference on the fan blade surface and condensation time, thereby effectively preventing or reducing water buildup. Operational energy efficiency is optimized: when heating or when a large airflow is required, the deflector plate is in the closed state, ensuring unobstructed airflow and minimizing wind resistance, improving fan efficiency, accelerating room temperature adjustment, and thus improving the overall energy efficiency ratio. Air delivery comfort is greatly enhanced: combined with the zone-controllable sweeping blade assembly 500, this invention can achieve multiple air delivery modes, such as rapid direct blowing mode, diffused gentle wind mode, and surround air delivery mode, meeting the comfort needs of users in different scenarios. Compact and highly reliable: The adjustment components adopt a linkage design, requiring only a few drive parts to control all the air intake plates. This simplifies the structure, reduces the failure rate and manufacturing cost, and facilitates retrofitting or integration into existing air conditioning products. Intelligent adaptive adjustment: Through linkage with the air conditioning control system, it can automatically select the optimal air intake plate angle and swing mode based on real-time operating parameters (such as fan current, set temperature, ambient temperature, etc.), without requiring manual user intervention, demonstrating a high degree of intelligence.

[0053] like Figures 1-13As shown, the present invention provides an air conditioner including the air outlet, which improves the overall energy efficiency ratio, stability, and user comfort of the air conditioner; specifically, the air conditioner includes: The aforementioned air outlets; It also includes a cross-flow fan blade 300 (containing a baffle 400 in the middle), which is disposed inside the air duct housing 600 and located behind the adjustment assembly.

[0054] Specifically, the air intake plate is positioned between the cross-flow fan blade 300 and the sweeping blades, and the air intake plates in the two sets of air guide units are positioned corresponding to the baffles 400 on the cross-flow fan blade 300. The air intake plate is positioned below the baffles 400 of the air conditioning cross-flow fan blade 300. Through shape changes in different modes, the bottom shell duct structure can be adaptively adjusted, thereby optimizing wind resistance and airflow distribution, and improving the uniformity of airflow and operating efficiency of the air conditioner.

[0055] In this embodiment, the drive mechanism includes a drive motor 100 and a stepper motor driver 200; the drive motor 100 is connected to the sweeping blade assembly 500. The cross-flow fan blade 300 adopts a conventional structural design, with multiple evenly distributed baffles 400 inside to separate airflow and maintain the stability of the fan blade structure. Its cross-section is specifically as shown below. Figure 5 As shown. A flow guide plate is fixedly installed below each septum 400. The top of the flow guide plate is connected to the linkage rod, as shown in the figure. Figure 10 and Figure 11 As shown. For ease of arrangement, holes can be made in the duct housing 600 to facilitate the connection between the linkage rod and the guide plate.

[0056] This invention applies advanced air outlet technology to end products, giving the air conditioner a competitive advantage in terms of uniform airflow, water-proof design, high energy efficiency, and high comfort.

[0057] When the air conditioner is first started, the sweeping blades are parallel and the air volume reaches its maximum. When it runs smoothly, the sweeping blade group 500 is divided into two parts, namely the left sweeping blade group 700 and the right sweeping blade group 800. All the sweeping blades of the left sweeping blade group 700 open to the left, and all the sweeping blades of the right sweeping blade group 800 open to the right, so that the air is delivered from both sides, achieving surround air delivery.

[0058] It should be noted that the transmission structure of the left and right sweeping blade groups can be similar to that of the adjustment component, as long as all the sweeping blades in the left sweeping blade group can swing simultaneously.

[0059] As a further improvement of the present invention, a control system is also included, which is configured to: In heating mode or when high airflow is required, the control and regulation components are in a closed state; In cooling mode, the control adjustment components are positioned at different deployment angles based on the operating parameters of the cross-flow fan blades 300.

[0060] This invention intelligently links the working state of the regulating component with the air conditioner's operating mode and the fan's status, achieving fully adaptive duct adjustment without user intervention. It is highly intelligent and can always ensure that the system operates in the optimal or near-optimal duct condition.

[0061] As a further improvement of the present invention, the operating parameters include the current of the motor 31 of the cross-flow fan 300, and the control system is configured as follows: When the detected current remains below the first threshold, the control adjustment component opens to the first angle; When a continuous abnormal current or fluctuation exceeding a preset range is detected, the control adjustment component opens to a second angle greater than the first angle.

[0062] Current is an effective indicator of fan load and airflow status. By judging the air volume and stability through the current threshold and adjusting the angle of the deflector plate in stages, real-time and accurate feedback control of airflow status is achieved, which effectively solves the problem of uneven airflow under low air volume.

[0063] As a further improvement of the present invention, the control system is also configured to control the sweeping blade assembly 500 to switch between parallel air supply mode and surround air supply mode based on the difference between the indoor ambient temperature and the set temperature.

[0064] This invention combines the air-sweeping mode with temperature control logic, so that the air delivery method serves the temperature regulation target: a large air volume direct blowing is used in the rapid temperature adjustment stage, and a comfortable and gentle wrap-around air delivery is used in the stable constant temperature stage, thereby maximizing user comfort while ensuring regulation efficiency.

[0065] As a further improvement of the present invention, the control system is also configured to trigger an alarm prompt if abnormal operating parameters are still detected after the control adjustment component is opened to the maximum angle.

[0066] This invention adds fault diagnosis and user prompt functions, improving product safety and user experience. When adaptive adjustment can no longer correct abnormalities (possibly due to external causes such as filter blockage), timely alarms can guide users to perform maintenance, preventing the equipment from operating in an abnormal state for extended periods.

[0067] The control system includes a control motherboard. The MCU on the control motherboard receives ambient temperature signals from a temperature sensor, current signals from the fan motor 31 of the current detection circuit, and user-defined mode setting signals. The MCU has pre-stored control logic. When set to "Heating Mode" or "High Power Mode", the MCU controls motor 31 to rotate the drain plate to the fully closed position (e.g., Figure 6 This forms a large-section air duct; at the same time, the sweeping blade assembly 500 is controlled to deliver air at a parallel angle.

[0068] When set to "cooling mode", the MCU first reads the current value I of the fan motor 31.

[0069] If I remains below the threshold I_Low (e.g., 85% of the rated current) for a time T1 (e.g., 1 minute), it is determined to be low airflow operation. The MCU controls motor 31 to open the air intake plate to angle a (e.g., 15°).

[0070] If the current I remains too low or fluctuates beyond the preset range, the MCU controls the current-carrying plate to open further to an angle b (e.g., 30°), where b > a.

[0071] If the system still determines that the airflow is abnormal, it controls the deflector to open to the maximum angle c (e.g., 45°) to form a narrow deflector channel to concentrate the airflow.

[0072] Simultaneously, the MCU controls the sweeping blade assembly 500 based on the difference ΔT between the room temperature and the set temperature. When the air conditioner is first started or when ΔT is large, the left and right air sweeping blade groups are controlled to swing synchronously or remain parallel to achieve rapid temperature adjustment over a wide range.

[0073] When the operation is stable and ΔT is small, the left sweeping blade group 700 is controlled to deflect to the left, and the right sweeping blade group 800 is controlled to deflect to the right, forming a ring-shaped air supply (e.g. Figure 13 This enhances comfort.

[0074] The basic control logic is as follows: Step 1: The system starts up and initializes the hardware.

[0075] Step 2: Determine the operating mode.

[0076] Step 3: If it is heating / high power mode, proceed to step 4; if it is cooling mode, proceed to step 5.

[0077] Step 4: Adjust the component to close, and the air sweeping blade assembly to deliver air in parallel at 500 degrees, thus ending this adjustment.

[0078] Step 5: Detect the fan current I.

[0079] Step 6: Determine if I remains below I_Low to T1. If yes, open the drainage plate to angle a.

[0080] Step 7: Continue monitoring to determine if the airflow is still uneven (e.g., large current fluctuations). If so, open the diversion plate to angle b.

[0081] Step 8: Monitor again to determine if the problem persists. If so, open the drainage plate to the maximum angle c and check if an alarm is needed.

[0082] Step 9: In parallel, adjust the sweeping blade group 500 mode (parallel or encircling) according to the temperature difference ΔT.

[0083] Step 10: Return to step 2 and perform cyclical monitoring and adjustment.

[0084] Specific usage instructions: In this embodiment, the two sets of flow guiding units are the first flow guiding unit 1 and the second flow guiding unit 2. The first flow guiding unit 1 includes a first flow guiding plate 11 and a first linkage rod 12; the second flow guiding unit 2 includes a second flow guiding plate 21 and a second linkage rod 22; there are two sets of drive components 3, which are respectively connected to the first flow guiding unit 1 and the second flow guiding unit 2.

[0085] When the air conditioner is in heating mode, specifically as follows: Figure 5 and Figure 6 As shown. Two motors 31 drive the first linkage 12 and the second linkage 22 respectively, causing the first guide plate 11 and the second guide plate 21 to move closer together, forming something resembling a single plate (in reality, there is a gap between them, indicating a parallel structure). All the first guide plates 11 and the second guide plates 21 are parallel, allowing air to be blown out parallel along the guide plates and finally exited through the sweeping blade assembly 500. Specifically, as shown... Figure 5 As shown. In addition, it works well with the cross-flow fan blades 300 to form a continuous and smooth air duct structure, thereby reducing wind resistance, increasing air volume, and achieving a rapid heating effect.

[0086] In cooling mode, such as Figure 7 and Figure 8 As shown, during the cooling start-up, the driver measures a low current on the drive motor 100 (current continuously less than 90% of the rated current for 1 minute), resulting in a low speed of motor 31. At this time, the control system controls the two motors 31 to drive the first linkage 12 and the second linkage 22 to open outwards at an angle of 'a', causing the airflow to concentrate in a specific direction, improving airflow uniformity and comfort. If the driver measures a still low current or a large fluctuation in current (exceeding the rated current ±10% for half a minute), the guide plate continues to open under the drive of motor 31, at an angle of 'b' (b > a). The air duct narrows, making the airflow more concentrated and further improving airflow uniformity. If the current test abnormality still occurs, the guide plate opens to the maximum angle 'c' (c > b > a). At this point, different groups of guide plates are closest to each other, and the airflow gap is the smallest, resulting in the fastest airflow. If the current test is still abnormal, the air conditioner will start an alarm, and the control system will stop the air conditioner. At this time, the filter needs to be cleaned (dirty filter affects airflow) or even professionally repaired.

[0087] By changing the opening angle of the deflector plate, the problems of water dripping from the cooling system and uneven airflow can be effectively avoided. If uneven airflow is still present even when the opening angle is set to c, the filter screen needs to be cleaned or even professionally repaired.

[0088] Based on the above control, the drive motor 100 controls the air-sweeping blade assembly 500 to intelligently adjust the air supply. When the air conditioner starts, the motor 31 controls the air-sweeping blades to run parallel, at which point the airflow is at its maximum, thereby achieving rapid cooling and heating, allowing the indoor temperature to reach the set temperature as quickly as possible. Specifically, as follows... Figure 12 As shown; when the air conditioner temperature stabilizes, the air sweeping blade assembly 500 is divided into two parts (the left air sweeping blade assembly 700 and the right air sweeping blade assembly 800), one part opens to the left and the other part opens to the right, as detailed below. Figure 13 As shown. The opening angle is adjusted according to the indoor temperature and the air conditioner's set temperature. If the temperature difference is large, the opening angle will be smaller; if the temperature difference is small, the opening angle will be larger. At this time, most of the air is delivered from the sides, and a small portion is delivered from the center, achieving wraparound airflow, greatly improving comfort and enhancing the quality of the air conditioning product.

[0089] This structure relies entirely on the airflow deflector to achieve automatic airflow regulation. It is simple in structure, responds quickly, and is highly reliable, making it suitable for various types of household air conditioning systems. Furthermore, by intelligently adjusting the swing blade angle using a stepper motor, it can significantly improve air conditioning comfort and enhance product quality.

[0090] This invention solves the technical problems of uneven airflow, unstable airflow distribution, and poor cooling effect in air conditioners during low-speed operation by combining a deflector plate, a cross-flow fan blade 300, and a base shell. Furthermore, intelligent adjustment of the sweeping blades improves comfort. A double-layered deflector plate is installed below each partition 400 of the cross-flow fan blade 300. In heating mode, two adjacent deflector plates in the two deflector units close in parallel, forming a structure similar to a parallel plate, reducing wind resistance and improving airflow output efficiency. In cooling mode, the deflector plates open in a V-shape, effectively streamlining the airflow direction and improving the concentration and uniformity of the airflow. This technical feature allows the air conditioner to automatically optimize the air duct structure under different operating conditions, effectively improving the energy efficiency ratio, reducing noise, and enhancing user comfort, thus achieving an overall performance improvement. In addition, intelligent control of the sweeping blades' operation at different temperatures further enhances comfort.
