Description

Technical Field

[0001] This invention relates to the field of air conditioning control technology, and in particular to a control method, device, equipment and storage medium for a dual-outlet wall-mounted air conditioner. Background Technology

[0002] Wall-mounted air conditioners are the mainstream equipment for indoor temperature regulation and are widely used in homes, offices and other scenarios. Their air outlet structure and operation control directly determine the comfort and regulation efficiency.

[0003] Currently, conventional wall-mounted air conditioners on the market are only equipped with a single front-facing air outlet. When cooling, the cold air blows directly onto people in a horizontal direction, which can easily cause problems such as dizziness and joint discomfort. In low-activity scenarios such as sleeping at night, the discomfort caused by direct airflow is even more pronounced. To avoid direct cold airflow, users usually manually reduce the indoor fan speed. This will directly lead to a reduction in air circulation volume, a significant decrease in cooling capacity, a slower room cooling speed, and uneven temperature distribution, failing to balance comfort and cooling performance.

[0004] Existing dual-outlet air conditioning technology is mostly applied to models such as cabinet air conditioners and ducted air conditioners. There is a significant lack of dedicated dual-air duct and dual-outlet structural designs for wall-mounted air conditioners, resulting in poor adaptability to different scenarios.

In this invention, the terms "first," "second," "third," "fourth," etc. (if present)," in the specification, claims, and accompanying drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments described herein can be implemented in a sequence other than that illustrated or described herein. Furthermore, the terms "comprising" or "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or devices.

[0019] This invention discloses a control method for a dual-outlet wall-mounted air conditioner, applicable to a wall-mounted air conditioner indoor unit structure. The main body of the dual-outlet wall-mounted air conditioner includes an air conditioner housing, with a front air outlet at the front and a lower air outlet at a corresponding position below the front air outlet. A first air guide plate is installed inside the front air outlet, and the front air outlet is sealed and connected to a first air duct inside the air conditioner. A second air guide plate is installed inside the lower air outlet, and the lower air outlet is sealed and connected to a second air duct inside the air conditioner. The first and second air ducts are independent of each other to ensure that the airflow does not interfere with each other. Both the first and second air guide plates are driven by independent stepper motors to achieve angle adjustment. The air conditioner is equipped with an indoor fan and a compressor as the core power and heat exchange components. It is also equipped with an ambient temperature and humidity acquisition component, a human body sensing component, and a control motherboard. The control motherboard can receive instructions and drive each execution component to complete the switching of air outlet mode and the adjustment of operating parameters.

[0020] For ease of understanding, the specific process of the embodiments of the present invention is described below. Please refer to [link / reference]. Figure 1 One embodiment of the dual-outlet wall-mounted air conditioner control method of the present invention includes: 101. When a power-on command is received, the front air outlet mode is executed, controlling the front air outlet to open and the lower air outlet to close. In this embodiment, after receiving the power-on command sent by the user via remote control or control panel, the control motherboard outputs an open signal to the stepper motor corresponding to the first air guide plate, driving the first air guide plate to rotate to the fully open position, so that the front air outlet is fully open. At the same time, it outputs a close signal to the stepper motor corresponding to the second air guide plate, driving the second air guide plate to rotate to the fully closed position, so that the lower air outlet remains closed. The air conditioner only delivers cold air through the front air outlet and the first air duct. By using a fixed front air outlet mode as the initial state of power-on, a large flow of cold air can be quickly delivered to the room, shortening the overall cooling time of the room. This meets the user's core need for rapid cooling upon power-on and avoids operational disorder caused by multiple air outlets operating simultaneously. It simplifies the control logic during the power-on phase, reduces the probability of initial operation failure, and ensures the stability and reliability of the air conditioner's start-up.

[0021] 102. When the preset pre-run time is met, obtain the real-time running parameters, and confirm the execution mode based on the real-time running parameters; In this embodiment, after the air conditioner continues to run in the previous air outlet mode for the preset pre-run time on the control motherboard, the control motherboard sends a data acquisition command. The temperature and humidity sensor and the human body sensor simultaneously collect indoor environmental operating parameters. The control motherboard compares the collected real-time operating parameters with the built-in mode determination threshold to determine the target air outlet mode that the air conditioner needs to execute next, i.e., the mode to be executed. Setting a fixed pre-run time can avoid frequent mode switching caused by fluctuations in environmental parameters at the beginning of startup, ensuring stable operation of the air conditioner. Matching the mode to be executed based on real-time operating parameters can make the air outlet mode match the current indoor environment's needs for temperature adjustment, dehumidification, and anti-direct blowing, improving the convenience and intelligence of air conditioner use.

[0022] 103. When the mode to be executed is the front air outlet mode, the lower air outlet is kept closed, and the working status of the air conditioner is adjusted based on the real-time operating parameters; In this embodiment, when it is determined that the mode to be executed is the front air outlet mode, a locking signal is continuously output to the stepper motor of the second air guide plate to keep the lower air outlet fully closed, stabilize the airflow direction and air volume of the front air outlet mode, and avoid airflow disturbance caused by dual air outlet interference. At the same time, according to the real-time collected ambient temperature difference parameters, adjustment signals are output to the indoor fan and compressor to dynamically adjust the air supply speed of the indoor fan and the operating frequency of the compressor to match the real-time cooling demand of the room. While ensuring the cooling effect, energy consumption output is optimized, the air conditioning cooling efficiency and operating economy are improved, and the front air outlet mode is always in the optimal operating state.

[0023] 104. When the mode to be executed is the down-ventilation mode, control the front air outlet to close and the down-ventilation outlet to open, and adjust the working status of the air conditioner based on the real-time operating parameters; In this embodiment, when it is determined that the mode to be executed is the down-ventilation mode, a shut-off signal is output to the stepper motor of the first air guide plate to drive the front air outlet to gradually close. At the same time, an open signal is output to the stepper motor of the second air guide plate to drive the down-ventilation outlet to gradually open. The cold air delivery path is changed to be delivered below the air conditioner, avoiding the horizontal cold air blowing directly on the human body and solving the discomfort of direct blowing in scenarios such as sleeping. After the air outlet switching is completed, the control board adjusts the operating status of the indoor fan and compressor according to the real-time temperature and humidity parameters to ensure that the cooling capacity does not decrease in the down-ventilation mode. This solves the technical problem that the anti-direct blowing and cooling efficiency cannot be balanced, and improves the dehumidification effect and user comfort in humid environments.

[0024] 105. When the mode to be executed is the dual air outlet mode, control the front air outlet to remain open and the lower air outlet to be open, and adjust the working status of the air conditioner based on the real-time operating parameters. In this embodiment, when it is determined that the mode to be executed is the dual-air outlet mode, the first air guide plate is kept fully open to keep the front air outlet continuously open. At the same time, an opening signal is output to the stepper motor of the second air guide plate to drive the lower air outlet to open synchronously. The dual air outlets deliver air at the same time, which can significantly improve the total air volume and heat exchange efficiency of the air conditioner, accelerate the indoor temperature adjustment speed, and adapt to the usage scenarios of large spaces and rapid cooling. The control board then optimizes the indoor fan speed and compressor operating frequency according to real-time environmental parameters, which can balance the cooling speed, energy consumption and airflow experience, expand the scenario adaptation range of the air conditioner, and make the dual-air outlet mode take into account both efficient cooling and comfortable user experience.

[0025] The dual-outlet wall-mounted air conditioner control method disclosed in this application is based on the structural foundation of dual independent air outlets and dual independent air ducts. It solves the technical problems of traditional single-outlet wall-mounted air conditioners, such as direct cold air blowing, reduced cooling capacity due to reduced air velocity, and poor scene adaptability, by fixing the initial air outlet mode upon startup, determining real-time parameters, and implementing three-mode hierarchical execution control rules. Specifically, the forced execution of the front air outlet mode upon startup can quickly establish indoor cooling capacity to match the user's immediate cooling needs. Based on real-time operating parameters, it can achieve unattended confirmation of the pending execution mode, reducing user operating costs. The three modes of front air outlet, bottom air outlet, and dual air outlet correspond to conventional cooling, anti-direct-blow dehumidification, and rapid temperature adjustment in large spaces, respectively. Through the opening and closing of the air outlets and the coordinated adjustment of core components, it can improve user comfort while ensuring cooling efficiency, and balance cooling effect, energy consumption, and user experience.

[0026] Furthermore, in this embodiment of the invention, the step of executing the front air outlet mode and controlling the front air outlet to open and the lower air outlet to close when a power-on command is received includes: 201. When a power-on command is received, the lower air outlet is kept closed, and the preset step angle, switching cycle, and high speed and normal cooling frequency corresponding to the front air outlet mode are obtained. In this embodiment, upon receiving the power-on command, a continuous lock signal is first output to the stepper motor of the second air guide plate to keep the lower air outlet in a fixed closed state, preventing interference from the dual air outlets during the power-on phase and avoiding turbulent airflow. Simultaneously, pre-stored control parameters are retrieved from the storage unit built into the control motherboard. The step angle is set to 1.5° to 3° per step, the switching cycle is set to 3 seconds to 5 seconds, the high speed of the indoor fan corresponding to the front air outlet mode is 75% to 85% of the rated speed, and the normal cooling frequency of the compressor is 60% to 80% of the rated frequency.

[0027] 202. Based on the step angle and switching cycle, adjust the angle of the first air guide plate so that the front air outlet gradually opens to 100% opening. In this embodiment, based on the pre-stored step angle and switching cycle, a continuous pulse signal is output to the stepper motor of the first air guide plate. The stepper motor drives the first air guide plate to rotate gradually at an angle of 1.5° to 3° per step, completing the action of the front air outlet from fully closed to fully open within a cycle of 3 to 5 seconds, ultimately making the front air outlet reach 100% opening. Through the smooth opening and closing of the first air guide plate, the wind noise and airflow impact caused by sudden opening and closing are avoided, improving the quietness of the air conditioner operation, while making the airflow process more gentle during startup, thus improving the initial user experience.

[0028] 203. Control the indoor fan of the wall-mounted unit to gradually increase to the high speed, and control the compressor of the wall-mounted unit to gradually increase to the normal cooling frequency, so that the wall-mounted unit executes the front air outlet mode; In this embodiment, a speed control signal is output to the indoor fan drive module to gradually increase the indoor fan speed to the pre-stored 75% to 85% of the rated speed range. At the same time, a frequency modulation signal is output to the compressor drive module to gradually increase the compressor operating frequency to the pre-stored 60% to 80% of the rated frequency range, so that the air conditioner can stably enter the front air outlet mode operation state. By gradually increasing the speed, the sudden change in current and load at the moment of startup can be avoided, reducing the wear and tear on the fan and compressor caused by the startup impact, extending the overall service life of the air conditioner, and ensuring the cooling effect of the front air outlet mode, quickly meeting the user's cooling needs at startup, and allowing the wall-mounted unit to quickly enter a high-efficiency cooling state after startup.

[0029] Furthermore, in this embodiment of the invention, the step of acquiring real-time running parameters when a preset pre-running time is met, and confirming the execution mode based on the real-time running parameters, includes: 301. When the preset pre-running time is met, the real-time operating parameters and the preset humidity threshold are obtained. The real-time operating parameters include the real-time ambient temperature, the user-set temperature, the real-time ambient relative humidity, and the human body sensing status. In this embodiment, after the preset pre-running time is met, the real-time ambient temperature and relative humidity are collected by a temperature and humidity sensor installed at the air inlet of the air conditioner indoor unit, and the presence status of a human body is collected by a human body sensor installed in the middle of the front panel of the air conditioner indoor unit. At the same time, the control board retrieves the set temperature value input by the user through the remote control or control panel, as well as the humidity threshold of 60% pre-stored by the board. By obtaining the real-time operating parameters and the preset humidity threshold, data support is provided for the determination of the mode to be executed, thereby improving the accuracy of mode matching.

[0030] 302. Calculate the real-time temperature difference based on the real-time ambient temperature and the user-set temperature; that is, subtract the collected real-time ambient temperature value from the user-set temperature value to obtain the quantified real-time temperature difference value.

[0031] 303. If the real-time temperature difference is greater than 3°C, then the mode to be executed will be determined as the dual-air-outlet mode; 304. If 1℃ < the real-time temperature difference ≤ 3℃, then the mode to be executed is determined as the front air outlet mode; 305. If the real-time temperature difference is ≤1℃ and the real-time ambient relative humidity is > a preset humidity threshold or the human body sensing state is that a human body is detected, then the mode to be executed is determined to be the down-ventilation mode. In this embodiment, when the real-time temperature difference is ≤1℃ and the real-time ambient relative humidity is >60%, or when the real-time temperature difference is ≤1℃ and the human body sensor detects the presence of a human body, it is determined to be a downward air outlet mode. By setting multi-level judgments for different scenarios, it can adapt to different usage needs such as rapid cooling, normal cooling, anti-direct blowing, and efficient dehumidification.

[0032] Furthermore, in this embodiment of the invention, when the mode to be executed is the front air outlet mode, controlling the lower air outlet to remain closed and adjusting the working state of the air conditioner based on the real-time operating parameters includes: 401. When the mode to be executed is the front air outlet mode, control the air guide plate of the lower air outlet to maintain 0% opening and control the air guide plate of the front air outlet to maintain 100% opening. In this embodiment, after confirming that the mode to be executed is the front air outlet mode, a lock signal is output to the stepper motor of the second air guide plate to maintain its 0% opening, and a lock signal is output to the stepper motor of the first air guide plate to maintain its 100% opening. The air guide plates do not have any active angle adjustment action, ensuring the stability of the air outlet direction and air volume in the front air outlet mode, avoiding airflow turbulence from affecting the cooling effect, and providing a stable air outlet basis for the subsequent dynamic adjustment of the fan and compressor.

[0033] 402. When 1℃ < the real-time temperature difference ≤ 3℃ and the real-time temperature difference increases, control the indoor fan to increase its speed, and when 2℃ < the real-time temperature difference ≤ 3℃, control the compressor to increase its frequency; In this embodiment, when the real-time temperature difference is 1℃ < ≤ 3℃ and the temperature difference continues to increase, the control board outputs an acceleration signal to the indoor fan to gradually increase the fan speed. When the real-time temperature difference is 2℃ < ≤ 3℃, a frequency modulation signal is simultaneously output to the compressor to increase the compressor's operating frequency. By actively adjusting the operating parameters according to the temperature difference change, the system can quickly respond to changes in cooling demand caused by indoor temperature rise, prevent indoor temperature from rising again, ensure air conditioning cooling efficiency, and ensure that the cooling effect always meets the user's needs.

[0034] 403. When 1℃ < the real-time temperature difference ≤ 3℃ and the real-time temperature difference decreases, control the indoor fan to reduce its speed, and when 1℃ < the real-time temperature difference ≤ 2℃, control the compressor to operate at the conventional cooling frequency; In this embodiment, when the real-time temperature difference is 1℃ < ≤ 3℃ and the temperature difference continues to decrease, the control board outputs a deceleration signal to the indoor fan to gradually reduce the fan speed. When the real-time temperature difference is 1℃ < ≤ 2℃, the compressor is controlled to maintain a normal cooling frequency of 60% to 80% of its rated frequency. Adjusting the operating parameters according to the temperature difference can reduce air conditioning energy consumption while meeting basic cooling needs, reduce unnecessary power loss, improve the economy of air conditioning operation, and ensure a smooth and shock-free dynamic adjustment process, thus guaranteeing a stable user experience.

[0035] Furthermore, in this embodiment of the invention, when the mode to be executed is the down-ventilation mode, controlling the front air outlet to close and the down-ventilation outlet to open, and adjusting the working state of the air conditioner based on the real-time operating parameters, includes: 501. When the mode to be executed is the down-outlet mode, based on the step angle and switching cycle, the angle of the first air guide plate is adjusted to gradually close the front air outlet to 0% opening, and the angle of the second air guide plate is adjusted to gradually open the down-outlet to 100% opening, while controlling the indoor fan to maintain the high speed. In this embodiment, once the mode to be executed is confirmed to be the down-discharge mode, a shut-off signal is output to the stepper motor of the first air guide plate according to the pre-stored step angle of 1.5° to 3° and a switching cycle of 3 seconds to 5 seconds, so that it gradually rotates to 0% opening. An open signal is output to the stepper motor of the second air guide plate, so that it gradually rotates to 100% opening. By smoothly switching the air outlet, airflow fluctuations and wind noise caused by sudden changes in the air conditioner's operating state can be avoided. At the same time, a constant speed signal is output to the indoor fan, so that it continuously maintains a high speed of 75% to 85% of the rated speed, ensuring the circulating air volume and heat exchange efficiency in the down-discharge mode, so that the cooling capacity does not decrease, and solving the technical problem that the anti-direct blowing and cooling capacity cannot be taken into account at the same time.

[0036] 502. Obtain the preset enhanced dehumidification frequency corresponding to the down-discharge mode; In this embodiment, the pre-stored enhanced dehumidification frequency parameter is retrieved from the storage unit built into the control motherboard. This parameter is set to 75% to 85% of the compressor's rated frequency, which can improve the evaporator's heat exchange efficiency and enhance the condensation dehumidification effect to match the dehumidification operation requirements in high humidity environments and ensure that the dehumidification effect is stable and controllable.

[0037] 503. When the real-time ambient relative humidity is greater than the preset humidity threshold, control the compressor to operate at the enhanced dehumidification frequency; In this embodiment, when the real-time ambient relative humidity is greater than the preset humidity threshold of 60%, the control motherboard outputs a frequency modulation signal to the compressor, causing it to operate at an enhanced dehumidification frequency of 75% to 85% of the rated frequency. This improves the heat exchange efficiency of the evaporator, accelerates the condensation rate of water vapor in the air, and quickly reduces indoor humidity, thus alleviating the stuffy and uncomfortable feeling caused by the humid environment. This is suitable for use in high-humidity environments such as the plum rain season in southern China.

[0038] 504. When the real-time ambient relative humidity is less than or equal to a preset humidity threshold, the compressor is controlled to operate at the normal cooling frequency. In this embodiment, when the real-time ambient relative humidity is ≤60% of the preset threshold, the control motherboard outputs a frequency modulation signal to the compressor, causing it to operate at a normal cooling frequency of 60% to 80% of the rated frequency. This ensures basic cooling performance while avoiding excessive dehumidification, maintaining indoor humidity balance, preventing discomfort caused by dry air, and optimizing overall user comfort.

[0039] Furthermore, in this embodiment of the invention, when the mode to be executed is the dual-air outlet mode, controlling the front air outlet to remain open and the lower air outlet to be open, and adjusting the working state of the air conditioner based on the real-time operating parameters, includes: 601. When the mode to be executed is the dual air outlet mode, control the first air guide plate to maintain 100% opening, and adjust the angle of the second air guide plate based on the step angle and switching cycle so that the lower air outlet gradually opens to 100% opening. In this embodiment, once the mode to be executed is confirmed to be the dual-airflow mode, a locking signal is output to the stepper motor of the first air guide plate to maintain it at 100% full opening. At the same time, according to the pre-stored step angle of 1.5° to 3° and the switching cycle of 3 seconds to 5 seconds, an opening signal is output to the stepper motor of the second air guide plate to gradually rotate it to 100% full opening. This achieves a smooth switching between the dual-airflow modes, avoids sudden changes in airflow and wind noise caused by the simultaneous opening of both air outlets, ensures a smooth and shock-free mode switching process, and improves the user experience.

[0040] 602. Obtain the preset ultra-high speed and high-efficiency cooling frequency corresponding to the dual air outlet mode; In this embodiment, the control motherboard retrieves the dedicated preset parameters for the dual-airflow mode from the built-in storage unit. The indoor fan's ultra-high speed is 90% to 100% of the rated speed, and the compressor's high-efficiency cooling frequency is 85% to 100% of the rated frequency. This parameter range can provide the maximum air volume and the highest cooling efficiency, meeting the needs of rapid temperature adjustment in large spaces under dual-airflow mode and significantly improving the air conditioning cooling speed.

[0041] 603. Control the indoor fan to gradually increase to the ultra-high speed, and control the compressor's operating frequency to gradually increase to the high-efficiency cooling frequency; 604. Adjust the working status of the hanging device based on the real-time temperature difference and the human body sensing status; In this embodiment, the control motherboard outputs an acceleration signal to the indoor fan, gradually increasing the speed to an ultra-high speed of 90% to 100% of the rated speed, and outputs a frequency modulation signal to the compressor, gradually increasing the frequency to a high-efficiency cooling frequency of 85% to 100% of the rated frequency. Then, combined with the real-time temperature difference and human body sensing status, the opening of the air guide plate and the fan speed are further optimized to achieve a balance between high-efficiency cooling and a comfortable experience, making the dual-air outlet mode adaptable to more complex usage scenarios.

[0042] Furthermore, in this embodiment of the invention, adjusting the working state of the wall-mounted device based on the real-time temperature difference and the human body sensing state includes: 701. When the real-time temperature difference is greater than 3°C and the human body sensing state is that no human body is detected, the air guide plate of the front air outlet is adjusted to 80% opening, and the air guide plate of the lower air outlet is adjusted to 20% opening. In this embodiment, when the real-time temperature difference is greater than 3°C and the human body sensing state is that no human body is detected, the control motherboard outputs an adjustment signal to the stepper motor of the first air guide plate to adjust it to 80% opening, and outputs an adjustment signal to the stepper motor of the second air guide plate to adjust it to 20% opening. By increasing the air outlet ratio of the front air outlet in unmanned scenarios, the cold air delivery distance can be extended, the cooling coverage can be expanded, and the cooling speed can be maximized to meet the rapid cooling needs of large spaces and unattended operation.

[0043] 702. When 1℃ < the real-time temperature difference ≤ 2℃ and the human body sensing state is that a human body is detected, control the air guide plate of the front air outlet to adjust to 30% opening, control the air guide plate of the lower air outlet to adjust to 70% opening, and control the indoor fan to adjust to the high speed. In this embodiment, when 1℃ < the real-time temperature difference ≤ 2℃ and the human body sensing state indicates that a human body is detected, the control motherboard outputs an adjustment signal to the stepper motor of the first air guide plate to adjust it to 30% opening, and outputs an adjustment signal to the stepper motor of the second air guide plate to adjust it to 70% opening. At the same time, it outputs a speed adjustment signal to the indoor fan to adjust the speed to a high speed of 75% to 85% of the rated speed. By reducing the air output ratio of the front air outlet and increasing the air output ratio of the lower air outlet in the presence of people, the direct blowing of horizontal cold air onto the human body can be avoided. Combined with the high speed to maintain a stable cooling capacity, it takes into account both user comfort and cooling effect, achieving the best balance between airflow and cooling capacity, and further improving the control level of the dual air outlet mode.
