Technical Field
[0001] This invention relates to the field of air conditioning technology, specifically to a control method for a dual-air guide vane air conditioner. Background Technology
[0002] As modern living environments continue to upgrade their demands for air conditioning quality, users have placed higher demands on the precise coverage and dynamic adaptability of air conditioning air delivery. Traditional single-air guide vane or double-rotating air guide vane systems use a simple structure that is directly hinged to the shell. Each air guide vane only performs a single rotational motion around a fixed axis, which limits the number of air outlet control methods and cannot meet the current needs of home air conditioning. Summary of the Invention
[0003] The purpose of this invention is to overcome the shortcomings of the prior art. This invention provides a control method for a dual-air guide plate air conditioner. By coordinating the control of the dual air guide plates, the air output of the air conditioner can be controlled in different modes, thereby improving the user's experience of using the air conditioner.
[0004] This invention provides a control method for a dual-air guide plate air conditioner, the dual-air guide plate air conditioner comprising: an upper air guide plate, a swing arm, a lower air guide plate, an air conditioner housing, a first drive motor for driving the upper air guide plate to rotate, a second drive motor for driving the swing arm to swing, and a third drive motor for driving the lower air guide plate to rotate; The upper air guide plate, the swing arm, and the lower air guide plate have intersecting motion trajectories in space and are driven sequentially by the first drive motor, the second drive motor, and the third drive motor. The upper air guide plate is connected to the housing via the swing rod. One end of the swing rod is hinged to the upper air guide plate, and the other end of the swing rod is mounted on the drive shaft of the housing to drive the upper air guide plate to rotate around the end of the swing rod and to translate as the swing rod swings. The lower air guide plate is hinged to the shaft hole of the housing, and the fixed-axis rotation is achieved based on the hinge connection;
[0005] The control method includes: When the air conditioner is turned on: the lower air guide plate is driven to move in the closing direction and lock the angle according to a preset sequence; after the swing arm is driven to move outward, the upper air guide plate is driven to move outward to the set angle. When turning off the air conditioner: drive the lower air guide plate to move in the closing direction in sequence. After the lower air guide plate is completely closed, drive the swing arm to move inward to close. After the swing arm is completely closed, drive the upper air guide plate to move inward to close.
[0006] Furthermore, the upper air guide plate includes an outer air guide plate component, an inner air guide plate component, and an aluminum strip; the aluminum strip is attached to the outer air guide plate component using sound-insulating foam, and the outer air guide plate component and the inner air guide plate component are fixed together by snap-fit. The swing arm is a rigid connecting rod, and one end of the swing arm connected to the air conditioner housing is fixed to the drive shaft of the housing. The swing angle range of the swing arm is 0°~210°. The rotation angle range of the lower air guide plate is 0°~160°.
[0007] Furthermore, the indoor unit of the air conditioner is equipped with a first drive motor for driving the upper air guide plate, a second drive motor for driving the swing arm, and a third drive motor for driving the lower air guide plate. The rated angular velocity of the first drive motor is 1.46° / s, the rated angular velocity of the second drive motor is 7.21° / s, and the rated angular velocity of the third drive motor is 1.83° / s.
[0008] Furthermore, the indoor unit of the air conditioner also includes radar for detecting the horizontal azimuth angle of a human body in the indoor space.
[0009] Furthermore, the control method includes a power-on reset step, which specifically includes: S101: Control the upper air guide plate to move upward to the first preset angle with the first angular velocity, and at the same time control the swing arm to move downward to the first preset angle with the second angular velocity; S102: The air guide plate moves downward to the second preset angle under the control of the third angular velocity; S103: Control the swing arm to move downward to the fourth preset angle using the second angular velocity; S104: Control the upper air guide plate to move outward to the fifth preset angle using the first angular velocity; S105: Control the upper air guide plate to move inward to the sixth preset angle using the first angular velocity; S106: Control the swing arm to move inward to the seventh preset angle using the second angular velocity; S107: The air guide plate moves upward to the eighth preset angle under the control of the third angular velocity.
[0010] Furthermore, the control method includes a power-on step, which specifically includes: S201: The air guide vane moves towards the closing direction by a locking angle under the control of the third angular velocity; S202: Detect the actual angle of the lower air guide plate. When it is greater than the first trigger threshold, control the swing arm to move outward with the second angular velocity. S203: Detect the actual angle of the swing arm. When it is greater than the second trigger threshold, control the upper air guide plate to move outward with the first angular velocity. S204: Controls the movement of each component to the user-defined angle.
[0011] Furthermore, the control method includes a shutdown step, which specifically includes: S301: The air guide vane moves in the closing direction under the control of the third angular velocity; S302: After the air guide plate is completely closed, the swing arm is controlled to move inward to close it with the second angular velocity; S303: When the lever is fully closed, the upper air guide plate is controlled to move inward to close with the first angular velocity; S304: When the upper air guide plate is completely closed, control its drive motor to rotate an additional stall angle and maintain the torque for a preset time of 200ms, during which the current of the drive motor is limited to 80% of the rated value.
[0012] Furthermore, it also includes radar-based dual-mode air supply control procedures: Wind Follows Person Mode: The radar detects the horizontal azimuth angle of the human body in the indoor space and controls the left and right sweeping motors and the upper and lower air guide plates to make the airflow point in the direction of the human body. Wind avoidance mode: After the radar detects a human body, the air guide plate automatically adjusts its angle to make the airflow bypass the human body and blow towards the uninhabited area.
[0013] Furthermore, it also includes: Cooling canopy mode: In cooling mode, control the upper air guide plate angle to 40°, the swing arm angle to 80°, and the lower air guide plate angle to 25°; Heated carpet fan mode: In heating mode, control the upper air guide plate angle to -95°, the swing arm angle to 70°, and the lower air guide plate angle to 78°.
[0014] This invention provides a control method for a dual-air guide plate air conditioner. By sequentially driving the upper air guide plate, the swing arm, and the lower air guide plate, interference caused by the intersection of motion trajectories is avoided. This effectively avoids interference between moving parts, prevents mechanical collisions and noise generation, and improves the reliability and accuracy of system operation. Through the coordinated adjustment of the dual air guide plates, the air outlet can be adjusted in different working modes of the air conditioner, thereby improving the user experience of the air conditioner.

Detailed Implementation
[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0018] Example: Please refer to Figures 1 to 7 This invention provides a control method for a dual-air guide plate air conditioner, the dual-air guide plate air conditioner comprising: The upper air guide plate 3 is one of the components at the air conditioner outlet used to guide the direction of airflow. Its movement is relatively complex; it can not only rotate around its own axis, but also translate with the swing of the lever 4, thereby achieving a wider airflow coverage.
[0019] The swing arm 4 is a linkage mechanism that connects the upper air guide plate 3 and the air conditioner housing 1. One end of the swing arm 4 is connected to the upper air guide plate 3, and the other end is mounted on the drive shaft on the air conditioner housing 1. By swinging the swing arm 4, the upper air guide plate 3 can achieve translational movement, while its own rotation is also constrained by the end of the swing arm 4.
[0020] The lower air guide plate 2 is another component at the air conditioner outlet used to guide the airflow direction. The lower air guide plate 2 is directly hinged to the shaft hole of the air conditioner housing 1, and its movement is relatively simple, only rotating around a fixed axis.
[0021] The first drive motor is specifically designed to drive the upper air guide plate 3 to rotate. This motor transmits power to the upper air guide plate 3 through a transmission mechanism, enabling it to adjust its angle.
[0022] The second drive motor is specifically designed to drive the swing arm 4 to achieve the swinging function. This motor drives the drive shaft mounted on the air conditioner housing 1, thereby causing the swing arm 4 to swing, which in turn causes the upper air guide plate 3 to move in a translational motion.
[0023] The third drive motor is specifically designed to drive the lower air guide plate 2 to achieve fixed-axis rotation. This motor transmits power to the lower air guide plate 2 through a transmission mechanism, enabling it to adjust its own angle.
[0024] The control method for the dual-air guide plate air conditioner involves the coordinated motion control of the upper air guide plate 3, the swing rod 4, and the lower air guide plate 2. The upper air guide plate 3 is connected to the air conditioner housing 1 via the swing rod 4. One end of the swing rod 4 is hinged to the upper air guide plate 3, and the other end is mounted on the drive shaft of the housing 1. This connection allows the upper air guide plate 3 to not only rotate around the end of the swing rod 4 but also to translate as the swing rod 4 swings. As one implementation, the upper air guide plate 3 can be designed to be connected to the swing rod 4 via a simple linkage mechanism that allows the upper air guide plate 3 to rotate within a limited range when the swing rod 4 swings. However, such a simple linkage mechanism may not provide sufficient degrees of freedom or precision to meet complex airflow requirements. The lower air guide plate 2 is directly hinged to the shaft hole of the air conditioner housing 1, allowing only fixed-axis rotation. For example, the lower air guide plate 2 can be designed to be connected to the housing 1 via a fixed pin that only allows the lower air guide plate 2 to rotate around its central axis. This fixed pin connection method may, in some cases, limit the rotation range of the lower air guide plate 2, or cause wear after long-term use.
[0025] To achieve precise control of the aforementioned air guide plate and swing arm 4, this embodiment employs three independent drive motors. Specifically, the first drive motor drives the upper air guide plate 3 to rotate, the second drive motor drives the swing arm 4 to swing, and the third drive motor drives the lower air guide plate 2 to rotate. For example, these drive motors can be stepper motors or DC motors, transmitting power to the corresponding moving parts via gear sets or belt drives. In one implementation, a single motor can be used to drive the movement of all three components through a complex mechanical linkage mechanism. However, this single-motor drive scheme may have limitations in terms of control precision, fault diagnosis, and motion flexibility.
[0026] Given that the upper air guide plate 3, the swing arm 4, and the lower air guide plate 2 have intersecting motion trajectories in space, this embodiment avoids motion interference by sequentially driving the first, second, and third drive motors. For example, without sequential driving, all components might be designed to start moving simultaneously. This simultaneous movement can easily lead to mechanical collisions when the component motion trajectories intersect, thereby damaging the components or causing the motors to stall. By using sequential driving, it can be ensured that at any given time, only components that will not interfere with each other move, or that the motion paths of the components are carefully planned to avoid other components.
[0027] This control method employs a specific sequential drive strategy for both air conditioner startup and shutdown. Specifically, when the air conditioner is started, the lower air guide plate 2 is first driven to move towards the closing direction by a locked angle according to a preset sequence. For example, the lower air guide plate 2 can be driven to a slightly closed position to ensure sufficient space for the subsequent movement of the swing arm 4 and the upper air guide plate 3. If the lower air guide plate 2 moves directly towards the fully open direction upon startup, it may collide with the swing arm 4 or the upper air guide plate 3, which is not yet fully deployed. Subsequently, the swing arm 4 is driven to move outward. For example, the swing arm 4 can be driven to an intermediate position to create conditions for the deployment of the upper air guide plate 3. If the swing arm 4 begins to move outward before the lower air guide plate 2 reaches the locked angle, it may interfere with the lower air guide plate 2. Finally, the upper air guide plate 3 is driven to move outward to a set angle. For example, the upper air guide plate 3 can be driven to the user-preset airflow angle. If the upper air guide plate 3 begins to move outward before the swing arm 4 is fully deployed, its movement may be obstructed or it may collide with the swing arm 4.
[0028] When the air conditioner is turned off, this control method also employs a strict sequential drive. First, the lower air guide vane 2 is driven sequentially in the closing direction. For example, the lower air guide vane 2 can be driven to the fully closed position. If the lower air guide vane 2 begins to close before other components have fully retracted, it may obstruct the movement of other components. After the lower air guide vane 2 is fully closed, the swing arm 4 is driven to move inward to close. For example, the swing arm 4 can be driven to the fully retracted position. If the swing arm 4 begins to retract before the lower air guide vane 2 is fully closed, it may collide with the lower air guide vane 2. After the swing arm 4 is fully closed, the upper air guide vane 3 is then driven to move inward to close. For example, the upper air guide vane 3 can be driven to the fully retracted position. If the upper air guide vane 3 begins to close before the swing arm 4 is fully retracted, it may cause its movement to be obstructed or collide with the swing arm 4. This step-by-step closing strategy ensures that all components can retract safely and completely.
[0029] Specifically, in this embodiment, it is assumed that user A starts a dual-air guide vane air conditioner at location A. The indoor unit of this air conditioner is equipped with an upper air guide vane 3, a swing arm 4, and a lower air guide vane 2, which are independently driven by a first drive motor, a second drive motor, and a third drive motor, respectively. Before the air conditioner is started, all air guide vanes and the swing arm 4 are in a fully closed or initial reset state. When user A presses the start button, the control system will operate according to a preset anti-interference sequence control method.
[0030] First, the control system activates the third drive motor, moving the lower air guide plate 2 towards a locked angle in the closing direction. For example, the lower air guide plate 2 is driven to a slight closing angle, ensuring that it does not obstruct the subsequent deployment of the swing arm 4 and the upper air guide plate 3. After the lower air guide plate 2 reaches this locked angle and stabilizes, the control system activates the second drive motor, driving the swing arm 4 outward. The outward movement of the swing arm 4 causes the upper air guide plate 3 to translate outward as a whole, creating space for its own rotation. When the swing arm 4 reaches the preset position, the control system activates the first drive motor, driving the upper air guide plate 3 to rotate outward to the user-set air delivery angle. Through this strict sequential drive, the movement trajectories of the lower air guide plate 2, swing arm 4, and upper air guide plate 3 will not intersect or collide during their respective movements, thus avoiding mechanical interference and abnormal noise.
[0031] When user A turns off the air conditioner at location A, the control system will reactivate the anti-interference sequential control method. First, the control system will activate the third drive motor to move the lower air guide plate 2 in the closing direction until it is completely closed. After the lower air guide plate 2 is completely closed and a feedback signal is received, the control system will activate the second drive motor to move the swing arm 4 inward until it is completely retracted. After the swing arm 4 is completely retracted and a feedback signal is received, the control system will activate the first drive motor to move the upper air guide plate 3 inward until it is completely closed. This sequential closing ensures that each component does not collide with other components during the retraction process and can accurately reset to the closed position, avoiding problems such as incomplete shutdown caused by component jamming or positional misalignment.
[0032] Based on the above examples, the technical solution of this embodiment demonstrates a significant technical contribution in solving the interference problem of air conditioning systems with multiple moving parts. In traditional air conditioning systems, the air guide vanes typically only undergo simple fixed-axis rotation, with relatively independent motion trajectories, thus requiring simultaneous drive or simple delayed drive. However, in the air conditioning system addressed in this embodiment, the upper air guide vane 3 achieves a combined rotational and translational motion through the swing arm 4, resulting in complex intersecting motion trajectories of the upper air guide vane 3, swing arm 4, and lower air guide vane 2 in space.
[0033] Compared to existing technologies that lack coordinated control methods for such complex motion structures, this embodiment introduces independent drive motors to precisely control the upper air guide plate 3, the swing arm 4, and the lower air guide plate 2, and builds a strict preset sequential drive strategy based on this. For example, when the air conditioner starts, if existing technologies use simultaneous driving, the lower air guide plate 2, the swing arm 4, and the upper air guide plate 3 may collide with each other during deployment, causing mechanical damage or noise. This embodiment, however, effectively avoids physical interference between components by driving the lower air guide plate 2 to the locked angle first, then driving the swing arm 4 outward, and finally driving the upper air guide plate 3 outward to the set angle. Similarly, when the air conditioner is turned off, if existing technologies do not implement sequential control, the components may collide or fail to fully reset during retraction. This embodiment ensures the safe retraction and accurate reset of the components by closing the lower air guide plate 2, the swing arm 4, and the upper air guide plate 3 one by one.
[0034] Therefore, the control method of this embodiment not only solves the problems of collision between three moving parts, abnormal noise during startup, inaccurate reset, and lack of protection against abnormalities caused by the lack of coordinated control in the prior art, but also ensures the stability and reliability of the air conditioning system in complex motion modes through precise sequential control, thereby improving user experience and product lifespan.
[0035] Specifically, the upper air guide plate 3 includes an outer air guide plate component, an inner air guide plate component, and an aluminum strip; the aluminum strip is attached to the outer air guide plate component by sound insulation foam, and the outer air guide plate component and the inner air guide plate component are fixed by snaps; the swing rod 4 is a rigid connecting rod, and one end of the swing rod 4 connected to the air conditioner housing 1 is fixed to the drive shaft of the housing 1, and the swing angle range of the swing rod 4 is 0°~210°; the rotation angle range of the lower air guide plate 2 is 0°~160°.
[0036] Specifically, the upper air guide plate 3 consists of an outer air guide plate component, an inner air guide plate component, and aluminum strips. The outer air guide plate component is typically a user-facing, decorative, and airflow-guiding shell, while the inner air guide plate component provides structural support and installation space, and the aluminum strips can be used to enhance structural strength, provide counterweight, or serve as part of the airflow guiding surface.
[0037] The outer and inner components of the air guide plate can be made of injection-molded plastic parts, while the aluminum strips can be made of extruded aluminum alloy profiles. The aluminum strips are attached to the outer components of the air guide plate using sound-absorbing foam. The sound-absorbing foam serves to dampen vibrations and reduce noise, thereby improving the stability and quietness of the upper air guide plate during movement. The sound-absorbing foam can be made of polyurethane foam or nitrile rubber foam and is fixed using adhesive backing.
[0038] The outer and inner components of the air guide plate are fixed together by snap-fit fasteners. Snap-fit fastening is a common, convenient, and detachable connection method that facilitates assembly and maintenance. The snap-fit fasteners can be designed as elastic barbed structures, achieving quick locking through pressing; or they can be designed as sliding groove structures, achieving positioning and fixation through sliding.
[0039] The swing arm 4 is defined as a rigid link, whose structural characteristics ensure that under the action of the drive motor, the swing arm 4 can stably and accurately transmit motion and force, avoiding deformation or vibration during movement, thereby ensuring the accuracy of the movement trajectory of the upper air guide plate 3. The rigid link can be made of solid or hollow metal rod, such as steel or aluminum alloy; or, the rigid link can be made of high-strength engineering plastic, such as PA+GF (glass fiber reinforced nylon).
[0040] One end of the swing arm 4 connected to the air conditioner housing 1 is fixed to the drive shaft of the housing 1. This fixed connection means that the connection is firm and there is no relative rotation, ensuring that the rotation of the drive shaft can be fully transmitted to the swing arm 4 to achieve precise swinging. The fixed connection can be achieved by keyway fitting, pin fixing or threaded fastening; or, the fixed connection can be achieved by interference fit or welding.
[0041] The swing angle range of the swing arm 4 is 0° to 210°. This angle range is crucial for ensuring the effective air delivery coverage area of the upper air guide plate 3 and avoiding collisions with other components. This angle range can be achieved through a mechanical limit structure or motor encoder feedback control.
[0042] The lower air guide plate 2 has a rotation angle range of 0° to 160°. This angle range is important for controlling the airflow direction, realizing different air supply modes (such as cooling canopy air, heating carpet air), and avoiding interference with the air conditioner housing 1 or other components. This angle range can be achieved through mechanical limit blocks or motor encoder feedback control; alternatively, this angle range can be set through software programs and combined with limit switches or magnetic sensors for position detection.
[0043] Specifically, the upper air guide plate 3 can be composed of an outer air guide plate component and an inner air guide plate component, both injection molded from polypropylene (PP) material, and are tightly fixed together by an integrally molded elastic snap-fit structure. The aluminum strip can be made of 0.5mm thick 6063 aluminum alloy profile, with an anodized surface, and is attached to the inner side of the outer air guide plate component using 2mm thick polyurethane sound-absorbing foam to provide additional structural support and effectively absorb vibration. The swing arm 4 can be a solid stainless steel rod with a diameter of 8mm, one end of which is fixed to the drive shaft via a spline, and the other end is hinged to the upper air guide plate 3 via a pin. The swing angle range of the swing arm 4 is monitored and controlled in real time by an encoder mounted on the drive shaft, ensuring precise movement between 0° and 210°. The lower air guide plate 2 can be injection molded from ABS engineering plastic, and its rotating shaft is hinged to the air conditioner housing 1 via an oil-impregnated bearing. Its rotation angle range is fed back by a Hall sensor mounted on the rotating shaft and precisely controlled between 0° and 160° by a third drive motor.
[0044] Specifically, the embodiments of the present invention further propose that the indoor unit of the air conditioner is provided with a first drive motor for driving the upper air guide plate 3, a second drive motor for driving the swing arm 4, and a third drive motor for driving the lower air guide plate 2; the rated angular velocity of the first drive motor is 1.46° / s, the rated angular velocity of the second drive motor is 7.21° / s, and the rated angular velocity of the third drive motor is 1.83° / s.
[0045] In one specific implementation, the indoor unit of the air conditioner can integrate three independent drive motors. For example, the first drive motor driving the upper air guide plate 3 can be a micro stepper motor with a rated angular velocity set to 1.46° / s, achieving rotation of the upper air guide plate 3 through precise pulse control. The second drive motor driving the swing arm 4 can be a fast-response brushless DC motor with a rated angular velocity set to 7.21° / s, achieving rapid swinging of the swing arm 4 through high-frequency PWM signal speed regulation. The third drive motor driving the lower air guide plate 2 can be a high-torque synchronous motor with a rated angular velocity set to 1.83° / s, achieving stable rotation of the lower air guide plate 2 through frequency converter control of its speed. These motors are connected to the corresponding air guide plate or swing arm 4 through their respective reduction gear sets, ensuring that the required torque and set angular velocity can be output during actual operation. For example, when the air conditioner starts, the control unit first sends a command to the third drive motor, causing it to move the lower air guide plate 2 towards the closing direction at a locked angle with a rated angular velocity of 1.83° / s; then, it sends a command to the second drive motor, causing it to move the swing arm 4 outward at a rated angular velocity of 7.21° / s; finally, it sends a command to the first drive motor, causing it to move the upper air guide plate 3 outward to a set angle with a rated angular velocity of 1.46° / s. The entire process, through a preset control program and precise motor parameters, ensures the coordination and non-interference of the movement of each component.
[0046] Specifically, the indoor unit of the air conditioner also includes radar for detecting the horizontal azimuth angle of a human body within the indoor space. Radar is a sensor that can detect the presence, movement, and location of a human body by emitting and receiving electromagnetic waves. Its implementation can be varied. For example, a millimeter-wave radar module can be used, which emits high-frequency electromagnetic waves and identifies the distance, speed, and angle information of a target object by analyzing the frequency, phase, and amplitude changes of the reflected waves, thereby accurately detecting a human body. Another implementation method is to use an ultrasonic sensor array, which constructs a human body distribution map of the indoor environment by measuring the round-trip time difference and intensity changes of ultrasonic waves. Furthermore, a composite sensor combining an infrared sensor can also be used, detecting the infrared radiation emitted by the human body and combining it with radar technology for positioning.
[0047] Detecting the horizontal azimuth of a human body in an indoor space refers to determining the angular position of the human body relative to the indoor unit of an air conditioner on a horizontal plane. This can be achieved through the beam scanning function of radar. The electromagnetic waves emitted by the radar scan horizontally, and when a human body's reflected signal is detected, the horizontal angle of the human body is calculated based on the direction of signal arrival or beamforming technology. For example, the radar can be configured with multiple receiving antennas, and the azimuth of the target object can be accurately calculated by comparing the phase difference of the signals received by different antennas. Alternatively, the radar can use step scanning or electronic scanning to cover a fan-shaped area in the horizontal direction and determine the direction of the human body based on the peak signal strength.
[0048] Specifically, an integrated millimeter-wave radar module can be installed in the indoor unit of the air conditioner. This module is typically located near the air outlet or inside the panel of the indoor unit to ensure a wide detection field of view. This millimeter-wave radar module can detect the horizontal azimuth of people indoors with high precision, for example, providing an azimuth accuracy of ±5°. When the air conditioner starts and enters intelligent air supply mode, the radar module operates continuously, sending the currently detected horizontal azimuth data of the human body to the air conditioner's main control board at regular intervals (e.g., 1 second). For example, if the radar detects a user located 30° to the left of the air conditioner's front, this azimuth data (e.g., -30°) will be sent to the main control board. Based on this azimuth data and the current operating mode of the air conditioner (e.g., cooling or heating), the main control board calculates the target angle combination that the upper air guide plate 3, the swing arm 4, and the lower air guide plate 2 need to achieve to direct the airflow to that -30° azimuth position. Subsequently, the main control board will drive the first drive motor, the second drive motor and the third drive motor in sequence according to the preset anti-interference sequence, so that the upper air guide plate 3, the swing arm 4 and the lower air guide plate 2 move to the calculated target angle, thereby achieving precise directional air delivery.
[0049] Specifically, the present invention proposes a power-on reset step, which aims to initialize key moving components such as the upper air guide plate 3, the swing arm 4, and the lower air guide plate 2 to a preset starting position or safe position after the air conditioning system is powered on.
[0050] The power-on reset step specifically includes: S101: controlling the upper air guide plate 3 to move upward to the first preset angle with a first angular velocity, and simultaneously controlling the swing arm 4 to move downward to the first preset angle with a second angular velocity; S102: The air guide plate 2 moves downward to the second preset angle under the control of the third angular velocity; S103: Control the swing arm 4 to move downward to the fourth preset angle with the second angular velocity; S104: Control the upper air guide plate 3 to move outward to the fifth preset angle with the first angular velocity; S105: Control the upper air guide plate 3 to move inward to the sixth preset angle using the first angular velocity; S106: Control the swing arm 4 to move inward to the seventh preset angle using the second angular velocity; S107: The air guide plate 2 moves upward to the eighth preset angle under the control of the third angular velocity.
[0051] Specifically, in this embodiment of the invention, the power-on reset step of the air conditioner can be implemented in the following manner. The air conditioner's control unit, such as an embedded microcontroller, will immediately initiate the power-on reset procedure after detecting a system power-on signal.
[0052] Specifically, in step S101, the microcontroller sends a command to the first drive motor driving the upper air guide plate 3, causing it to rotate upward at a first angular velocity, and simultaneously sends a command to the second drive motor driving the swing arm 4, causing it to swing downward at a second angular velocity. The movement of these two components continues until the upper air guide plate 3 reaches its first preset angle, and the swing arm 4 also reaches its corresponding first preset angle.
[0053] Subsequently, in step S102, the microcontroller controls the third drive motor that drives the lower air guide plate 2 to rotate downward at a third angular velocity until the lower air guide plate 2 reaches the second preset angle.
[0054] Next, in step S103, the microcontroller controls the second drive motor again, causing the swing arm 4 to move downward at a second angular velocity until it reaches the fourth preset angle.
[0055] In steps S104 and S105, the microcontroller controls the first drive motor to make the upper air guide plate 3 move outward to the fifth preset angle with the first angular velocity, and then move inward to the sixth preset angle, thereby calibrating its position sensor.
[0056] In step S106, the microcontroller controls the second drive motor to make the swing arm 4 move inward at a second angular velocity until it reaches the seventh preset angle.
[0057] Finally, in step S107, the microcontroller controls the third drive motor to move the lower air guide plate 2 upward at a third angular velocity until it reaches the eighth preset angle. Through this series of precisely controlled steps, all air guide plates and swing rods 4 can be reliably reset to their known initial states, thus laying the foundation for subsequent normal operation.
[0058] Specifically, the air conditioner start-up steps in this embodiment of the invention include: controlling the lower air guide plate 2 to move in the closing direction by a locking angle with a third angular velocity; detecting the actual angle of the lower air guide plate 2, and when it is greater than a first trigger threshold, controlling the swing arm 4 to move outward with a second angular velocity; detecting the actual angle of the swing arm 4, and when it is greater than a second trigger threshold, controlling the upper air guide plate 3 to move outward with a first angular velocity; and controlling each component to move to the angle set by the user.
[0059] The purpose of controlling the lower air guide plate 2 to move towards the closing direction by a locking angle with a third angular velocity is to create a safe space for the subsequent movement of the swing arm 4 and the upper air guide plate 3 by pre-adjusting the position of the lower air guide plate 2 during the initial stage of air conditioner startup, thus avoiding potential mechanical interference. Moving the lower air guide plate 2 to a "locking angle" rather than completely closing it may mean reserving an initial position for certain startup modes or airflow directions, or simply removing it from areas that might collide with the swing arm 4 or the upper air guide plate 3. This step can be achieved by monitoring the actual rotation angle of the lower air guide plate 2 in real time using the encoder or Hall sensor of the third drive motor. When the preset locking angle is reached, the drive of the third drive motor is stopped. Alternatively, a limit switch can be set on the movement path of the lower air guide plate 2. When the limit switch is triggered, it indicates that the lower air guide plate 2 has reached the locking angle, thereby stopping the drive.
[0060] The actual angle of the lower air guide plate 2 is detected. When it exceeds the first trigger threshold, the swing arm 4 is controlled to move outward with a second angular velocity. This step introduces feedback-based sequential control to ensure that the swing arm 4 only starts moving after the lower air guide plate 2 has reached a safe position. This avoids interference caused by the swing arm 4 moving prematurely before the lower air guide plate 2 is fully in place. This detection can be achieved by continuously monitoring the angle of the lower air guide plate 2 using an angle sensor (such as a rotary encoder or potentiometer) mounted on its shaft, and comparing the angle value with the preset first trigger threshold. Alternatively, image recognition technology can be used to capture the real-time position of the lower air guide plate 2 using a miniature camera, and its angle can be calculated using image processing algorithms to determine whether the trigger condition has been met.
[0061] The actual angle of the swing arm 4 is detected. When it exceeds the second trigger threshold, the upper air guide plate 3 is controlled to move outward with a first angular velocity. This step further ensures that the swing arm 4 has moved to a sufficiently "outer" safe position, making room for the movement of the upper air guide plate 3, thereby preventing the upper air guide plate 3 from colliding with the swing arm 4 before it is fully extended. This detection can be achieved by using an angle sensor (such as a rotary encoder or magnetic encoder) mounted on the drive shaft of the swing arm 4 to obtain the actual angle of the swing arm 4 in real time and compare it with the preset second trigger threshold. Alternatively, multiple photoelectric sensors or proximity switches can be set along the movement path of the swing arm 4. When the swing arm 4 passes through a specific position, the sensors are triggered to indirectly determine whether it has reached or exceeded the second trigger threshold.
[0062] The final stage of the startup sequence involves controlling the movement of each component to the user-defined angle. This stage aims to adjust the upper air guide plate 3, the swing arm 4, and the lower air guide plate 2 to the user's desired airflow angle to meet personalized airflow needs. The control system can receive angle setting commands input by the user via remote control, smartphone app, or air conditioner panel. Based on these commands, it drives the first, second, and third drive motors respectively, precisely moving the upper air guide plate 3, swing arm 4, and lower air guide plate 2 to the target position. Furthermore, multiple airflow modes (such as direct blowing, sweeping, and avoidance of people) can be preset, each corresponding to a set of preset component angles. When the user selects a mode, the control system automatically adjusts each component to the angle corresponding to that mode.
[0063] Specifically, the shutdown steps of the air conditioner in this embodiment of the invention include: controlling the lower air guide plate 2 to move in the closing direction with a third angular velocity; after the lower air guide plate 2 is completely closed, controlling the swing arm 4 to move inward to close with a second angular velocity; after the swing arm 4 is completely closed, controlling the upper air guide plate 3 to move inward to close with a first angular velocity; after the upper air guide plate 3 is completely closed, controlling its drive motor to rotate an additional stall angle and maintain the torque for a preset time of 200ms, wherein the current of the drive motor is limited to 80% of the rated value during the stall period.
[0064] When the air conditioner is turned off, the system prioritizes controlling the lower air guide vane 2 to move in the closing direction with a third angular velocity. This ensures that the lower air guide vane 2 returns to its position before other components move, providing space for subsequent components to close or avoiding potential collisions. Only after the lower air guide vane 2 is confirmed to be completely closed does the system control the swing arm 4 to move inward to close with a second angular velocity. This triggering mechanism based on the completion of the previous action effectively prevents the swing arm 4 from moving before the lower air guide vane 2 is completely closed, thus preventing mechanical interference between components. Next, after the swing arm 4 is also completely closed, the system controls the upper air guide vane 3 to move inward to close with a first angular velocity. This strict sequential control further ensures that the upper air guide vane 3 closes only after the swing arm 4 has returned to its position, avoiding collisions or jamming that may be caused by complex cross-movement trajectories. More importantly, when the upper air guide vane 3 is completely closed, its drive motor (first drive motor) does not stop immediately, but is controlled to rotate an additional stall angle and maintain torque for a preset time of 200ms. During the stall period, the drive motor's current is limited to 80% of its rated value. This design allows the upper air guide plate 3 to maintain a continuous, controlled, slight thrust even after reaching the physically closed position. This thrust effectively eliminates loosening caused by mechanical clearances, manufacturing tolerances, or wear from long-term use, ensuring a tight, seamless closure between the upper air guide plate 3 and the air conditioner housing 1 or other components. By limiting the flow to 80% of the rated value, sufficient holding torque is ensured for a tight closure, while avoiding overheating or damage that could result from prolonged motor stall, thus extending motor life and reducing energy consumption. The entire process, through precise sequence control and end-point torque maintenance, enables the dual-air guide plate air conditioner to achieve a smooth, interference-free, tight, and reliable closure upon shutdown.
[0065] Specifically, when the user issues a shutdown command, the air conditioner's control unit first sends a command to the third drive motor, causing it to rotate the lower air guide plate 2 inward at an angular velocity of 1.83° / s until it is fully closed. The complete closure of the lower air guide plate 2 can be detected by a microswitch installed at the end of its movement path, or confirmed by feedback from the encoder inside the third drive motor indicating that its rotation angle has reached a preset closing angle. Once the closing signal of the lower air guide plate 2 is received, the control unit immediately sends a command to the second drive motor, causing it to drive the swing arm 4 inward at an angular velocity of 7.21° / s until it is fully retracted. The complete closure of the swing arm 4 can also be confirmed by its limit switch or encoder feedback. After the swing arm 4 is fully closed, the control unit then sends a command to the first drive motor, causing it to rotate the upper air guide plate 3 inward at an angular velocity of 1.46° / s until it is fully closed. When the limit switch of the upper air guide plate 3 is triggered or its encoder feedback indicates that the closing angle has been reached, the control unit will further adjust the control strategy of the first drive motor. At this time, the first drive motor will not be immediately de-energized, but will continue to be driven with a controlled low current (e.g., by PWM control, keeping the motor current at 80% of the rated current), generating a continuous holding torque and maintaining this state for 200ms. This additional stall action ensures a tight fit between the upper air guide plate 3 and the air conditioning panel, eliminating any potential gaps or wobbling.
[0066] Specifically, the radar-based dual-mode air supply control includes: wind-following-person mode, where the radar detects the horizontal azimuth angle of the human body in the indoor space and controls the left and right sweeping motors and the upper and lower air guide plates 2 to link the airflow in the direction of the human body.
[0067] The system also includes a "wind avoidance mode," where, upon radar detection of a human body, the air deflector automatically adjusts its angle to direct airflow away from the person and towards an unoccupied area. An infrared sensor array can be used to determine a person's location by detecting their infrared radiation. In this solution, the radar primarily acquires real-time horizontal azimuth information of the indoor human body distribution, providing data input for subsequent intelligent airflow control. The dual-mode airflow control step refers to the air conditioning system intelligently selecting either "wind follows people" or "wind avoids people" mode based on the human body location information detected by radar. This enables personalized and comfortable airflow distribution, avoiding the discomfort caused by the fixed airflow mode of traditional air conditioners, and improving the accuracy and efficiency of airflow.
[0068] The "Wind Follows Person" mode is an active airflow strategy that directs airflow towards the direction of the person. In this mode, the system uses radar to detect the horizontal azimuth angle of the person and controls the movement of the left and right sweeping motors and the upper and lower air guide plates 2 (including the upper air guide plate 3, the swing arm 4, and the lower air guide plate 2) to ensure that the airflow from the air conditioner is precisely directed towards the area where the person is located. This mode is suitable for scenarios where users want to quickly experience hot or cold airflow, or where a specific area needs to quickly reach a set temperature.
[0069] The wind avoidance mode is an air delivery strategy that prevents airflow from directly hitting people. In this mode, when radar detects a person, the control system calculates the area where the person is located and automatically adjusts the angle of the air guide plates (including the upper air guide plate 3, the swing arm 4, and the lower air guide plate 2) to direct the airflow around the person and towards other unoccupied areas in the room. This mode aims to improve user comfort and avoid discomfort that may be caused by prolonged direct airflow, and is especially suitable for users sensitive to direct airflow or scenarios requiring gentle airflow. The left and right sweeping motors are actuators used to drive the air guide mechanism inside the air conditioner vent to achieve horizontal (left and right) airflow. It can be a stepper motor or a DC motor, connected to the control system, receiving commands and precisely controlling the left and right swing angle of the air guide mechanism, thereby changing the horizontal direction of the airflow. In dual-mode air delivery control, the left and right sweeping motors work in conjunction with the upper and lower air guide plates 2 to achieve precise airflow guidance in three-dimensional space.
[0070] Specifically, when the air conditioner starts and enters air supply mode, the radar continuously detects the horizontal azimuth angle of a person in the indoor space. Based on the human position information fed back by the radar, and combined with user-preset or system-default air supply preferences, the control system intelligently selects between "Follow-the-Person Mode" and "Avoid-the-Person Mode." In "Follow-the-Person Mode," the control system accurately calculates the required linkage angles for the upper air guide plate 3, swing arm 4, lower air guide plate 2, and left and right sweeping motors based on the detected horizontal azimuth angle of the human body. Subsequently, through the coordinated drive of the first, second, and third drive motors, as well as the left and right sweeping motors, the upper air guide plate 3, swing arm 4, and lower air guide plate 2 are adjusted to the target angle while avoiding motion interference, and, in conjunction with the left and right sweeping motors, the airflow is precisely guided towards the direction of the human body. In "Avoid-the-Person Mode," the control system also utilizes the human body position detected by radar, but its goal is to calculate the angle of the air guide plate that allows the airflow to bypass the human body and blow towards an unoccupied area. At this point, the first drive motor, the second drive motor, the third drive motor, and the left and right sweeping motors will work together again to drive the upper air guide plate 3, the swing arm 4, and the lower air guide plate 2 to adjust to a new angle, ensuring that the airflow does not blow directly onto the human body. Throughout the process, the cross-movement trajectory of the upper air guide plate 3, the swing arm 4, and the lower air guide plate 2, as well as their sequential drive mechanism, ensure that no collision occurs between the components when making complex angle adjustments, thereby ensuring the stability and reliability of the air supply control.
[0071] Specifically, the indoor unit of the air conditioner can integrate a millimeter-wave radar module, which can detect the horizontal azimuth information of people indoors with high accuracy. When the user selects the "Follow Person Mode," for example, if the millimeter-wave radar detects that the user is located at approximately 45 degrees to the right of the air conditioner vent, the control system will calculate the target angle combination required for the upper air guide plate 3, the swing arm 4, the lower air guide plate 2, and the left and right sweeping motors based on this azimuth angle. For example, the left and right sweeping motors can be instructed to swing to the right at a certain angle. At the same time, the first drive motor drives the upper air guide plate 3 to rotate, the second drive motor drives the swing arm 4 to swing, and the third drive motor drives the lower air guide plate 2 to rotate, so that the three work together to adjust the vertical and horizontal directions of the airflow towards the user. Conversely, when the user selects the "Avoid Person Mode," if the millimeter-wave radar detects that the user is sitting directly in front of the air conditioner, the control system will calculate the angle of the air guide plates to avoid that area. For example, the left and right sweeping motors can be instructed to swing left or right, while the upper air guide plate 3, the swing arm 4 and the lower air guide plate 2 are driven to an upward or downward angle, so that the airflow can blow over the user from above or to the side, avoiding direct blowing.
[0072] Specifically, in the cooling skylight mode, the upper air guide plate 3 is controlled at an angle of 40°, the swing rod 4 at an angle of 80°, and the lower air guide plate 2 at an angle of 25°. These specific angle combinations are optimized to achieve the skylight effect in cooling mode. The combination of the upper air guide plate 3 swinging 40°, the swing rod 4 swinging 80°, and the lower air guide plate 2 swinging 25° allows the airflow to diffuse upwards and forwards. Utilizing the high density of cold air, it is slowly lowered, thus achieving uniform cooling of the room and preventing cold air from blowing directly on people, improving comfort. In the heating carpet mode, the upper air guide plate 3 is controlled at an angle of -95°, the swing rod 4 at an angle of 70°, and the lower air guide plate 2 at an angle of 78°. These specific angle combinations are optimized to achieve the carpet effect in heating mode. The combination of the upper air guide plate (3-95°), the swing rod (470°), and the lower air guide plate (278°) allows the airflow to diffuse downwards and forwards. Utilizing the low density of hot air, it causes it to rise slowly, thereby achieving uniform room heating, preventing warm air from stagnating at higher levels, and improving heating efficiency and comfort.
[0073] Furthermore, in the cooling skylight mode, the system controls the first, second, and third drive motors to adjust the upper air guide plate 3 to 40°, the swing arm 4 to 80°, and the lower air guide plate 2 to 25°. This specific combination of angles allows the cold air blown out by the air conditioner to diffuse upwards and forwards. Utilizing the physical properties of cold air, which is denser and naturally sinks, the cold air slowly sinks along the ceiling and walls, thus creating a uniform cooling effect throughout the room and avoiding the discomfort caused by cold air blowing directly on the body.
[0074] Specifically, when a user turns on the air conditioner and selects the cooling mode in summer, the air conditioner controller first executes the startup sequence to ensure that the air guides move without interference. Then, if the user or the system has selected the cooling ceiling mode by default, the controller sends commands to the first, second, and third drive motors. The first drive motor precisely rotates the upper air guide 3 to 40°, the second drive motor swings the swing arm 4 to 80°, and the third drive motor rotates the lower air guide 2 to 25°. At this point, the cool air blown out by the air conditioner will diffuse along the ceiling, avoiding direct airflow onto the human body. Furthermore, based on the characteristic that cold air sinks, it allows the cold air to quickly diffuse throughout the room, thereby improving the indoor cooling effect.
[0075] Specifically, in the heated carpet mode, the system controls the first, second, and third drive motors to adjust the upper air guide plate 3 to -95°, the swing arm 4 to 70°, and the lower air guide plate 2 to 78°. This angle combination allows the warm air blown out by the air conditioner to diffuse downwards and forwards. Utilizing the physical properties of hot air, which has a lower density and naturally rises, the warm air rises slowly along the ground, creating a uniform "carpet-like" heating effect at the bottom of the room. This effectively solves the problem of warm air stagnating at higher levels and resulting in lower ground temperatures in traditional heating modes, improving heating efficiency and comfort. By pre-setting and precisely controlling the coordinated movement of these three air guide plates, the control method of this application can intelligently adjust the airflow direction and airflow organization according to the air conditioner's operating mode, thereby achieving personalized airflow that better meets human comfort needs while ensuring uninterrupted movement.
[0076] Furthermore, when a user turns on the air conditioner and selects the heating mode in winter, after completing the startup sequence, if the user or the system has selected the heating carpet mode by default, the controller will send instructions to the corresponding drive motors. The first drive motor will precisely rotate the upper air guide plate 3 to -95°, the second drive motor will swing the swing arm 4 to 70°, and the third drive motor will rotate the lower air guide plate 2 to 78°. At this time, the warm air blown out by the air conditioner will diffuse along the ground. Based on the characteristic that hot air rises, this allows the warm air in the room to diffuse evenly from bottom to top, thereby improving the indoor heating effect.
[0077] Through the above technical solutions, this application, while ensuring uninterrupted movement of the dual-air guide vane air conditioner, further provides optimized air delivery strategies for cooling and heating modes. In cooling ceiling mode, a specific combination of air guide vane angles allows cold air to diffuse along the ceiling and slowly descend, effectively avoiding discomfort caused by direct cold air blowing on the body and improving cooling comfort. In heating carpet mode, another specific combination of air guide vane angles allows warm air to diffuse along the floor and slowly rise, solving the problem of warm air stagnating at higher levels and lower floor temperatures in traditional heating modes, significantly improving heating efficiency and overall room comfort. These modular air delivery controls enable the air conditioner to better adapt to different seasons and user needs, providing a more user-friendly and energy-efficient operating experience.
