Description

Technical Field

[0001] This invention relates to the field of air conditioning control technology, and in particular to an air conditioner, an air conditioner control method, and a computer-readable storage medium. Background Technology

[0002] During operation, the air conditioner compressor is prone to generating low-frequency noise under low-load conditions (such as low-load operation at night). One reason for this phenomenon is that the discharge pressure is too low, causing the compressor vanes to be pressed too low and unable to press against the rotor in time. Long-term low-frequency noise may accelerate compressor wear. In addition, the heat dissipation fins of the air conditioner outdoor unit are exposed to the outdoor environment for a long time and are easily blocked by insects, leaves, dust, etc., resulting in reduced heat dissipation efficiency, triggering overheat protection shutdown or reduced energy efficiency.

[0003] Current technologies typically involve installing dust filters to prevent blockages in air conditioner outdoor units. However, these filters require frequent manual cleaning and maintenance and have limited insect-proofing effects. Suppressing low-frequency noise from the air conditioner compressor primarily involves controlling the airflow. This airflow control relies on fan speed adjustment, such as with inverter fans. However, this method cannot accurately respond to low-frequency noise, and high-speed fan operation increases energy consumption, leading to high equipment maintenance costs.

[0020] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] In existing technologies, dust filters are typically installed to prevent blockage of the outdoor unit of an air conditioner. However, these filters require frequent manual cleaning and maintenance and have limited insect-proofing effects. Suppressing low-frequency noise generated by the air conditioner compressor is mainly achieved by controlling the airflow of the air conditioner. However, the airflow control of the outdoor unit relies on fan speed adjustment, such as variable frequency fans. But this method cannot accurately respond to low-frequency noise, and high-speed fan operation increases energy consumption, resulting in high equipment maintenance costs.

[0022] One of the core concepts of this invention is that by adjusting the coverage area of ​​the dustproof cloth assembly on the condenser, the airflow through the condenser can be regulated, thereby reducing the airflow to increase the exhaust pressure. This suppresses fin vibration and noise caused by insufficient pressure, effectively solving the low-frequency noise problem under low-load conditions at night, helping to reduce wear and extend the life of core components. Driving the dustproof cloth to cover the condenser forms a physical airtight barrier, effectively preventing insects, fallen leaves, and dust from clogging the outdoor unit of the air conditioner, reducing the frequency and intensity of manual cleaning, lowering equipment maintenance costs, and helping to maintain the air conditioner in a long-term, efficient, and stable operating state.

[0023] Reference Figure 1 The diagram shows a structural block diagram of the outdoor unit of an air conditioner provided in an embodiment of the present invention. The air conditioner includes: Dustproof cloth assembly 101 is disposed on the outside of the condenser of the outdoor unit 10 of the air conditioner, and is used to cover or expose the condenser to block foreign objects and regulate the airflow through the condenser; Traditional air conditioner outdoor units have long faced two major problems: low-frequency noise disturbing residents at night, and the heat dissipation fins being easily clogged by dust and insects, leading to decreased efficiency.

[0024] The core innovation of this invention lies in adding an adjustable-length dustproof cloth assembly to the rear and sides of the outdoor unit of the air conditioner. The dustproof cloth's coverage area over the condenser of the outdoor unit allows for real-time dynamic control of airflow, thus addressing low-frequency compressor noise and clogging issues. Airflow control indirectly stabilizes the exhaust pressure. Increasing the dustproof cloth's coverage area over the condenser reduces airflow and increases condenser exhaust pressure, thereby suppressing noise. Simultaneously, the dustproof cloth completely covers the condenser, preventing insects and clogging.

[0025] The outdoor unit of an air conditioner is the outdoor unit in a residential split-type air conditioning system. It is connected to the indoor unit (wall-mounted, floor-standing, etc.) via refrigerant pipes and electrical wires, forming a complete cooling or heating cycle system. It is the "main unit" responsible for core heat exchange and compression functions. Key components include the compressor and condenser.

[0026] The dustproof cloth assembly is a movable covering mechanism installed on the air inlet side of the condenser of the air conditioner outdoor unit in this embodiment of the invention. As an adjustable air resistance mechanism: by changing its coverage area on the condenser, it continuously and in real time adjusts the airflow through the condenser, thereby actively intervening in the system operating pressure and suppressing low-frequency noise from the compressor. As a physical barrier: when needed, it fully unfolds to tightly cover the condenser, preventing dust, leaves, insects, and other foreign objects from entering, thus actively preventing dirt and blockage.

[0027] In this embodiment of the invention, the dustproof cloth assembly is disposed on the outside of the condenser of the air conditioner outdoor unit (i.e., the air inlet side). By precisely moving its physical position, it dynamically changes the coverage area of ​​the condenser, thereby actively and continuously regulating the cooling airflow through the condenser. When noise reduction is required, the coverage area is increased to improve air resistance, thereby interfering with the pressure parameters of the refrigeration system and precisely suppressing low-frequency noise from the compressor. Secondly, when protection is required, it completely covers the condenser to form a sealed barrier, fundamentally preventing the intrusion of dust, insects, and other foreign objects.

[0028] In practical implementation, this component functions through an electromechanical system. The dust cover assembly typically consists of a low-permeability canvas, a drive shaft, guide rails, and a position feedback device. The dust cover is wound around the shaft and moves along the guide rails, controlled by a drive unit integrated into the outdoor unit. In noise reduction mode, when a vibration sensor detects a specific low-frequency characteristic, the control motor unfolds the dust cover to a specific position (e.g., covering 50% of the area), reducing airflow and increasing exhaust pressure to eliminate the noise source. In anti-clogging mode, when the system detects that the outdoor unit is stopped or the ambient wind speed is too low, it automatically unfolds the dust cover to 100% coverage, achieving full sealing protection.

[0029] The dustproof cloth assembly becomes a key device connecting the "sensing layer" (sensors) and the "execution layer" (pressure regulation / physical protection). Through real-time linkage with compressor vibration signals and ambient wind speed signals, it achieves closed-loop control from "sensing the problem" to "physical intervention." During noise reduction, it simultaneously achieves more stable system pressure control, and during protection, it enables zero-energy shutdown maintenance. This allows the outdoor unit to intelligently switch between three modes—"heat dissipation," "silent operation," and "unit protection"—based on its own operating status and the external environment, achieving comprehensive performance improvement at a relatively low hardware cost.

[0030] A drive device 102 is connected to the dustproof cloth assembly 101 and is used to drive the dustproof cloth assembly 101 to move in order to change the coverage area of ​​the dustproof cloth assembly 101 on the condenser. The drive unit is the power and transmission actuator that converts the commands issued by the control unit into the mechanical actions required by the dustproof cloth assembly. Its core function is to receive control signals and precisely drive the dustproof cloth to unfold or retract to achieve the target coverage area.

[0031] The drive unit is an electromechanical module with a motor at its core. The core power source is the motor, whose output shaft is directly coaxially connected to the rotating shaft A or C (core reel) of the dustproof cloth assembly. The control unit calculates the target coverage area (e.g., 45% coverage required) based on sensor data (such as "excessive vibration"), and then converts this target into an instruction for the drive unit. Upon receiving the instruction, the motor driver begins precise rotation. Through a transmission mechanism, this drives the dustproof cloth rotating shaft, unfolding the dustproof cloth from the storage axis into the working area, or retracting it in the opposite direction. During movement or after reaching the target, position sensors (such as encoders) on the dustproof cloth assembly provide real-time feedback of the "actual coverage position" to the control unit. The control unit compares the "target position" with the "actual feedback position." If the position is not perfect, a correction instruction is issued, and the drive unit continues to fine-tune until a perfect match is achieved. This ensures control accuracy and prevents accumulated errors.

[0032] In this embodiment of the invention, the drive device is the key actuator for achieving dynamic physical adjustment. Its core purpose is to translate the commands from the control device into linear mechanical motion of the dust cover assembly, thereby adjusting the condenser coverage area. When the operating status acquisition device (such as a vibration sensor) detects specific low-frequency noise characteristics generated by the compressor, the control device immediately calculates the target air resistance required to increase exhaust pressure and suppress noise based on a preset algorithm, and translates this into a specific "target coverage area" command (e.g., covering 52%). The drive device starts instantly upon receiving this electrical signal command.

[0033] At the execution level, the drive unit typically consists of a motor and a matching transmission mechanism. It controls the unfolding and retraction of the canvas by directly driving the shaft of the dust cover assembly. During the unfolding of the dust cover to increase the coverage area, position sensors (such as encoders) continuously feed back the actual position of the fabric to the control unit, forming a position closed loop to ensure precise stopping at the target point. Simultaneously, the drive unit incorporates overcurrent protection and fault logic. If jamming occurs or a high-voltage alarm is received, it will immediately reverse the movement to reduce coverage, always prioritizing system safety.

[0034] In noise reduction mode, it performs fine-tuning to find a balance between noise reduction and heat dissipation efficiency. In anti-clogging mode, it performs a full-stroke movement, fully unfolding the dust cover to a sealed state, forming a physical barrier. When the air conditioner starts or the system resets, it unconditionally retracts the dust cover to zero, ensuring that the heat dissipation channel is completely unobstructed. Therefore, every action of the drive unit is an intelligent adaptation to the operating status of the outdoor unit and the external environment, enabling the single dust cover component to work together to achieve two completely different functions: a "variable wind resistance device" and an "automatic protective cover" at different times and under different needs.

[0035] The operating status acquisition device 103 is used to monitor the operating status of the compressor of the outdoor unit 10 of the air conditioner; The operating status acquisition device is a sensor device in this embodiment of the invention responsible for sensing and acquiring key operating parameters of the air conditioner outdoor unit. Its core function is to capture abnormal characteristics of the compressor operation in real time, especially vibration signals that induce low-frequency noise. It also monitors external environmental conditions to provide a basis for triggering the anti-clogging mode.

[0036] Operating status acquisition devices typically consist of multiple sensors, each collecting data on different physical quantities. The core monitoring component is a vibration sensor (crucial for noise diagnosis), which is directly attached to or rigidly connected to the compressor body or base. This sensor directly captures mechanical vibrations inside the compressor, especially the low-frequency vibrations (10-30Hz) generated by the impact of the vanes and rotor, which are the source of airborne noise. MEMS accelerometers (such as the ADXL355) are usually chosen because these sensors have high sensitivity, a wide frequency response range, and can effectively capture weak low-frequency signals.

[0037] The acquired raw vibration signal contains various types of noise (such as fan vibration and road resonance). Therefore, signal processing algorithms (such as bandpass filtering and spectrum analysis) are responsible for extracting the characteristic frequency components and their amplitudes related to the low-frequency noise of the compressor from the complex signal, providing effective input for subsequent judgment.

[0038] The auxiliary monitoring consists of pressure / temperature sensors (used for safety and efficiency monitoring), installed on the compressor's discharge line. Monitoring the discharge pressure reflects the heat load on the condenser side and the system pressure level, and is a key safety parameter for determining whether over-coverage may occur, potentially triggering high-pressure protection. Discharge temperature and pressure are complementary, more directly reflecting the compressor's operating conditions and load; excessively high temperature is a direct indication of compressor overload. The data provided by these sensors not only serves as auxiliary optimization input for noise reduction control algorithms (more accurately linking airflow and pressure), but more importantly, it provides redundancy for system safety.

[0039] Environmental monitoring uses a wind speed sensor (for triggering the anti-clogging mode), installed on the side or top of the outdoor unit to avoid direct interference from the fan exhaust. It monitors ambient wind speed. When the wind speed remains below a preset threshold (e.g., 1 m / s) and the air conditioner is off, it indicates that the outdoor unit is stationary and there is no natural wind for cleaning, which is the ideal condition to trigger the automatic anti-clogging mode (completely closing the dust cover).

[0040] In this embodiment of the invention, the core task of the operating status acquisition device is to capture the internal operating characteristics of the compressor. High-precision vibration sensors are directly mounted on the compressor housing to collect its structural vibration signals in real time. Using advanced signal processing algorithms embedded in the control device (such as bandpass filtering and Fast Fourier Transform (FFT), characteristic vibration components and their energy amplitudes in specific low-frequency ranges (e.g., 10-30Hz) are accurately separated and quantified from the complex original vibration waveform. This process essentially converts physical vibration into "low-frequency noise characteristics" that can be recognized by the control system, thereby determining whether the compressor is in an abnormal operating condition where insufficient exhaust pressure causes vane vibration and produces a "ticking" sound.

[0041] Once the analyzed characteristic vibration amplitude exceeds a preset threshold, the system immediately determines that the "noise suppression condition" is met and triggers an airflow adjustment command. More importantly, after the dust cover moves, the device continuously monitors the amplitude change of this characteristic vibration, providing real-time feedback to the control device to determine whether the noise reduction effect is up to standard and whether further adjustment of the coverage area is needed, thereby achieving closed-loop precise control based on noise cancellation effect. In addition, the device can also integrate pressure or temperature sensors as safety redundancy monitoring, providing a safety protection signal that exceeds the vibration logic when the system pressure or temperature rises abnormally due to adjustment.

[0042] The control device 104 is used to acquire the operating status of the compressor monitored by the operating status acquisition device 103; and based on the operating status, control the drive device 102 to drive the dustproof cloth assembly 101 to move, and adjust the coverage area of ​​the dustproof cloth assembly 101 on the condenser.

[0043] In this embodiment of the invention, the control device continuously acquires and parses the data reported by the operating status acquisition device. Its core task is to perform real-time diagnosis and strategy decision-making. When the amplitude of a specific low-frequency vibration characteristic of the compressor exceeds a preset threshold, it determines to enter "noise suppression mode"; when the outdoor unit is detected to be shut down or the ambient wind speed is consistently too low, it determines to enter "anti-clogging mode". The control device does not mechanically respond to a single signal, but rather performs a fusion judgment based on multi-source data (vibration spectrum, pressure, temperature, wind speed) and follows strict priority logic (e.g., safety protection takes precedence over noise reduction, and noise reduction is only triggered during operation), thereby making conflict-free and optimal command decisions in complex operating scenarios.

[0044] After the decision is made, the control device enters the execution control phase. For noise reduction mode, based on the degree of vibration exceeding the limit, the built-in algorithm calculates the target coverage area required to stabilize the pressure and converts it into precise pulse commands that the drive device can execute. While driving the dust cover, the control device continuously receives vibration feedback to judge the effect and adjusts the commands in real time until the noise is eliminated; at the same time, it strictly monitors the exhaust pressure / temperature to ensure that the coverage area is always constrained within the safe upper limit, and if it is exceeded, it immediately terminates the coverage and performs a retraction action.

[0045] In some embodiments, the control device 104 is used to determine whether the outdoor unit 10 of the air conditioner meets preset noise suppression conditions or anti-clogging conditions based on the operating state; if the outdoor unit 10 of the air conditioner meets the noise suppression conditions, the control device 102 is controlled to drive the dustproof cloth assembly 101 to move, so as to increase the coverage area of ​​the dustproof cloth assembly 101 on the condenser; or if the outdoor unit of the air conditioner meets the anti-clogging conditions, the control device 102 is controlled to drive the dustproof cloth assembly 101 to move, so that the dustproof cloth assembly 101 completely covers the condenser.

[0046] The noise suppression condition is the sum of quantitative standards and logical criteria that the control device must meet to determine the current operating state of the air conditioner compressor and initiate active noise reduction intervention (i.e., adjusting the dust cover coverage area). The core of the determination condition is the vibration signal of the compressor body. The vibration is mainly concentrated in a specific low-frequency band of 10Hz–30Hz, which is the core feature for identifying the "compressor vane tapping" characteristic. High-frequency vibration may originate from the fan or motor. The determination is made whether the vibration amplitude of this specific low-frequency band exceeds a preset first threshold to assess the severity. Slight vibration is permissible; intervention is only required when it reaches an "exceeding" level. When the air conditioner is in cooling / heating operation and the compressor is in a low-to-medium load condition (usually corresponding to lower frequency operation), the noise at high load is mainly caused by a large air volume, and the exhaust pressure itself is high, making it less likely to generate this low-frequency noise.

[0047] The anti-fouling condition, in this embodiment of the invention, is a series of logical criteria that the control device must meet to determine that the outdoor unit of the air conditioner is currently in a state requiring physical protection, thereby triggering the complete closure of the dustproof cloth and the formation of a sealed barrier. Its core objective is preventative maintenance, not operational adjustment. The core of this condition is to identify that the outdoor unit is in a non-working or extremely low-risk state. Specifically, the air conditioning system as a whole enters a shutdown state (the compressor and outdoor fan have both stopped running). Its purpose is to allow the system to enter protection mode regardless of day or night or season, as long as it is shut down. A specific condition is that the environmental wind speed sensor detects that the wind speed is consistently below a preset threshold (e.g., ≤1m / s). Auxiliary conditions are used to expand the protection scenarios. When the air conditioner is in standby mode but not completely powered off (e.g., during low-temperature nighttime periods) and there is no wind outside, dust and catkins easily adhere to it; this condition can provide intelligent protection even when the air conditioner is not completely shut down.

[0048] In this embodiment of the invention, the control device parses the raw data stream sent by the operating status acquisition device and performs real-time diagnosis using embedded intelligent algorithms (such as spectrum analysis, threshold comparison, and timing logic). If the analysis reveals that the compressor vibration signal continuously exceeds the standard and has a characteristic frequency (10-30Hz), it is determined that the noise suppression condition is met; if it is detected that the outdoor unit has completely stopped or is in a standby "dormant" state with no wind, it is determined that the anti-clogging condition is met.

[0049] Once the corresponding conditions are met, the control device immediately issues a clear instruction to the drive device, driving the dust cover assembly to execute a patterned response. For noise suppression mode, the instruction is "increase coverage area." The control device fine-tunes the coverage area in real time based on vibration feedback, finding effective coverage points to eliminate noise and strictly locking the upper limit of coverage within a safe range, achieving a balance between noise reduction, energy efficiency, and safety. For anti-clogging mode, the instruction is complete coverage, an action with a clearly defined endpoint, designed to form a physical sealing barrier. Regardless of the mode, the control device has a built-in ultimate safety logic: once abnormal exhaust pressure or temperature is detected, all instructions are immediately overridden, and the dust cover is forcibly retracted to ensure the inherent safety of the system. Through real-time diagnosis and mode adjudication of the operating status by the control device, low-frequency vibrations and dust accumulation during shutdown can be proactively identified, and precise handling can be automatically triggered, elevating the user experience from passive tolerance to proactive protection. The control device triggers two differentiated execution strategies based on drastically different conditions: during noise reduction, dynamic closed-loop adjustment is used to precisely suppress noise with minimal energy cost, avoiding excessive coverage that could lead to a surge in energy consumption or system overload. When preventing blockage, a complete sealing is used to achieve physical protection with zero energy consumption.

[0050] In some embodiments, the operating status acquisition device 103 includes a vibration acquisition device disposed on the compressor body and the exhaust pipe; The vibration acquisition device is used to acquire vibration signals during the operation of the compressor; The control device 104 is used to acquire the vibration signal collected by the vibration acquisition device; perform spectrum analysis on the vibration signal to obtain the corresponding vibration amplitude, and determine whether the vibration amplitude exceeds a first preset amplitude threshold; if the vibration amplitude exceeds the first preset amplitude threshold and the operating state is a normal operating state, then it is determined that the air conditioner outdoor unit 10 meets the noise suppression condition.

[0051] The vibration acquisition device is a sensor specifically designed to monitor the mechanical vibration of the compressor within the operational status acquisition system. Its purpose is to directly capture structural vibration signals generated by insufficient exhaust pressure in the compressor's internal mechanical components (especially the vanes and rotor). Its core function is to provide fault characteristic information as the sole or primary trigger for noise suppression functions. After noise reduction control actions are executed, it provides real-time feedback signals to evaluate the control effectiveness and guide subsequent adjustments.

[0052] The optimal installation location is the top or side of the compressor housing, as close as possible to the internal mechanical center of the compressor. This location is sensitive to vane vibration. Secondary locations are the compressor's common base or rigidly connected exhaust pipes. Vibration signals at these locations are attenuated and distorted after being transmitted through the structure, but they are still effective monitoring points.

[0053] In this embodiment of the invention, the vibration acquisition device (such as a high-precision MEMS accelerometer) is directly installed on key structures for vibration transmission, such as the compressor body and exhaust pipe. Its purpose is to capture the original state of the mechanical motion inside the compressor, rather than the attenuated and mixed sound waves after propagation through the air. After acquiring the original vibration signal, the control device immediately performs spectral analysis. The vibration waveform in the time domain is decomposed into a spectrum in the frequency domain, thereby accurately separating and quantifying the vibration energy (i.e., vibration amplitude) in a specific low-frequency band (such as 10-30Hz) directly related to the slip vane strike fault. Interference from other irrelevant frequencies such as those from fans, motors, and road traffic is filtered out, ensuring the purity of the diagnostic target.

[0054] After extracting the characteristic vibration amplitude, the control device performs a crucial intelligent judgment. First, it determines whether the characteristic amplitude exceeds a first preset amplitude threshold, which is a quantitative limit representing a "clearly perceptible or harmful noise level." Simultaneously, it must confirm that the air conditioner is in normal operating condition. Normal operating condition typically means the compressor is operating at a low to medium load using inverter technology, rather than during startup, shutdown, or high load. This is because at extremely high loads, the system pressure is already high, making it less likely to generate this specific noise. This dual judgment mechanism ensures that the system intervenes only under the correct operating conditions, addressing the correct issue, fundamentally avoiding false triggers and ineffective actions, and achieving precise, energy-saving intelligent noise reduction triggering.

[0055] In some embodiments, the control device 104 is configured to continuously monitor the amplitude change of the vibration amplitude after increasing the coverage area of ​​the dustproof cloth assembly 101 over the condenser; if the vibration amplitude drops below a second preset amplitude threshold, the control device 102 is configured to drive the dustproof cloth assembly to maintain the current coverage area or reduce the coverage area over the condenser; if the vibration amplitude is higher than the second preset amplitude threshold, the control device 102 is configured to continue driving the dustproof cloth assembly 101 to further increase the coverage area over the condenser; the second preset amplitude threshold is less than or equal to the first preset amplitude threshold.

[0056] In this embodiment of the invention, when the control device determines that the noise suppression condition is met based on a first threshold and instructs the dustproof cloth to increase its coverage area, a dynamic optimization process begins. The control device continuously monitors the characteristic vibration amplitude, after spectral analysis, fed back from the vibration sensor, and compares this amplitude with a more stringent second preset amplitude threshold. This second threshold (less than or equal to the first threshold) sets the "benchmark" for successful noise reduction, representing that the noise has been suppressed to an acceptable or essentially eliminated level. The goal at this point is to find and stabilize the necessary coverage area that can suppress the vibration amplitude below the second threshold.

[0057] Based on continuous amplitude comparison, the control device makes intelligent decisions. If the vibration amplitude is below the second threshold, it indicates that the current coverage area is sufficient to eliminate noise. At this point, the control device may instruct the drive unit to maintain the current coverage area to consolidate the noise reduction effect; or, in pursuit of higher energy efficiency, it may attempt to slightly reduce the coverage area to test whether a low-noise state can still be maintained with less wind resistance, thereby achieving a fine balance between noise reduction effect and heat dissipation efficiency. If the vibration amplitude is still above the second threshold, it indicates that the current intervention is insufficient. The control device will instruct the drive unit to continue increasing the coverage area, further increasing wind resistance and system pressure, until the vibration amplitude is suppressed below the threshold.

[0058] Throughout the adjustment process, the increase in coverage area is always strictly constrained by a preset upper limit. Once the upper limit is reached, even if the vibration amplitude does not meet the standard, the system will stop covering and may instead use other logic (such as slightly increasing the fan speed) to assist, prioritizing ensuring that the system does not overload. This feedback-driven dynamic adjustment avoids unnecessary energy efficiency losses due to over-coverage and prevents noise from being unable to be eliminated due to insufficient coverage. Through dynamic fine-tuning, it always operates near the point of just eliminating noise, achieving a balance between intelligent noise reduction and system energy efficiency.

[0059] In some embodiments, during the process of increasing the coverage area of ​​the dustproof cloth assembly over the condenser, the coverage area does not exceed a preset upper limit value; the preset upper limit value is the maximum allowable coverage area corresponding to ensuring that the outdoor unit of the air conditioner can maintain the minimum safe heat dissipation requirements.

[0060] The preset upper limit is directly related to the core safety indicators of the air conditioning refrigeration system: condensing pressure and exhaust temperature. The essence of the upper limit is that when the dust cover covers a large area (i.e., the airflow is low), the resulting increase in condensing pressure and compressor load must be strictly limited within the long-term reliable capacity of the compressor and piping components, and must not trigger the system's high-pressure or over-temperature protection. Therefore, this "maximum allowable coverage area" ensures that the air conditioner's heat dissipation capacity, even in noise reduction mode, still meets the requirement of maintaining the system pressure below the safe threshold; it is the critical point for balancing "noise reduction benefits" and "safety risks."

[0061] During the noise reduction closed-loop adjustment process, this preset upper limit is written into the control logic as a hard interruption condition or boundary condition. Regardless of whether the vibration amplitude has dropped below the target threshold, as long as the coverage area of ​​the dustproof cloth reaches this upper limit, the control device must immediately stop the command to continue increasing the coverage. This design directly prevents dangerous situations from occurring, such as infinitely increasing the coverage in pursuit of ultimate quietness, leading to insufficient heat dissipation of the condenser, which in turn causes a sharp rise in exhaust pressure and temperature. The consequences may include compressor overload and wear, lubricating oil carbonization, seal damage, and even frequent start-stop of the system's high-pressure protection, seriously damaging the equipment's lifespan and reliability. By forcibly setting an upper limit, this embodiment of the invention strictly limits the active noise reduction intervention within the absolute boundary of the system's safe operation, ensuring that this innovative function does not sacrifice the core lifespan and operational safety of the equipment, thus guaranteeing the equipment's service life.

[0062] In some embodiments, the control device 104 is used to determine that the outdoor unit 10 of the air conditioner meets the anti-clogging condition when the operating state is a shutdown state.

[0063] In this embodiment of the invention, the air conditioner outdoor unit entering a shutdown state is the primary and sufficient condition for activating active protection. The shutdown state refers to the point where both the compressor and the outdoor fan have stopped operating, and the air conditioning system no longer performs active heat exchange cycles. The fundamental principle lies in recognizing the transformation of the air conditioner outdoor unit from a dynamically operating device to a statically exposed device. When the outdoor unit is operating, the continuous high-speed airflow itself has a certain self-cleaning and anti-adhesion effect; however, once it stops, the gaps between the heat dissipation fins easily become ideal accumulation sites for insects, catkins, and dust. Therefore, activating protection at the moment of shutdown is a timely response to the vulnerable idle period of the equipment.

[0064] It achieves fully automatic and seamless protection. Users do not need to operate the system. The system can automatically complete the "covering" action after each shutdown (whether it is a short shutdown at night or a long period of idleness during the season), integrating preventive maintenance into the equipment's life cycle.

[0065] In some embodiments, the control device 104 is used to control the drive device 102 to drive the dustproof cloth assembly 101 to move so that the condenser is fully exposed when the air conditioner is powered on or malfunctions.

[0066] In this embodiment of the invention, when the air conditioner is powered on or malfunctions, the control drive device moves the dust cover assembly to fully expose the condenser. The fundamental purpose is to ensure that the air conditioner can start or operate in a safe, low-risk default configuration under any uncertain initial state or system anomaly. Setting full condenser exposure as a mandatory state essentially defines the complete unobstructed heat dissipation channel as a high-priority safety benchmark for the system. If the dust cover is stuck in the covered position due to a previous power outage, or if it is accidentally covered due to control logic malfunction, the air conditioner will face an extremely dangerous situation when starting up: the condenser will be obscured, resulting in severely insufficient heat dissipation. This could easily trigger compressor overload, system high-pressure protection, or even permanent damage. Therefore, this step is the ultimate guarantee that the entire intelligent additional function will not compromise the safety of the main unit.

[0067] First, there's the forced reset upon power-on initialization. Regardless of the dust cover's previous state (partially or completely covered), as soon as the air conditioner is powered on again, the control device will send an unconditional command before running any user logic, driving the dust cover to fully retract to zero. This is confirmed by the position sensor, clearing obstacles for the upcoming cooling cycle. Second, there's proactive safety intervention under fault monitoring. When the control device detects an abnormal system operation through self-testing or sensors (such as pressure and temperature sensors), and determines it may be related to insufficient airflow, it will immediately trigger the fault handling procedure. One of the highest priority actions is to forcibly retract the dust cover, restoring it to the basic heat dissipation state, creating conditions for fault diagnosis and preventing further damage. By forcibly setting a full exposure safety benchmark in both initial and abnormal states, the possibility of the air conditioner starting or operating in a dangerous state of obstructed heat dissipation due to its own faults (such as program errors, motor jamming, or sensor malfunctions) is fundamentally eliminated. This ensures that the introduction of additional functions does not reduce the safety and reliability of the original air conditioner, addressing users' concerns about the risk of "out of control" of smart devices.

[0068] In some embodiments, the air conditioner further includes a pressure acquisition device and a temperature acquisition device disposed on the compressor; The pressure acquisition device is used to monitor the operating pressure of the compressor; The temperature acquisition device is used to monitor the exhaust temperature of the compressor; The control device 104 is used to acquire the operating pressure and exhaust temperature of the compressor monitored by the pressure acquisition device and the temperature acquisition device; if either the operating pressure or the exhaust temperature of the compressor exceeds the corresponding safety threshold, the control device 102 is controlled to drive the dustproof cloth assembly 101 to move, so as to reduce the coverage area of ​​the dustproof cloth assembly 101 on the condenser.

[0069] The pressure and temperature acquisition devices are priority safety monitoring devices independent of the main control logic (vibration noise reduction) in this embodiment of the invention. They continuously monitor the thermodynamic state of the refrigeration cycle to prevent system overload and damage caused by any reason. Their core function is to provide an absolutely reliable safety backup based on physical laws for noise reduction control based on vibration analysis.

[0070] The pressure acquisition device is installed on the compressor exhaust pipe to monitor the effective location of the high-pressure side pressure. The temperature acquisition device is installed close to the outer wall of the compressor exhaust pipe (it needs to be wrapped with heat insulation material to ensure good contact) or directly inserted into the temperature sensing bladder of the exhaust pipe. During air conditioning operation, it continuously sends pressure and temperature signals to the control unit. The control unit has two safety thresholds: the pressure safety threshold (P_max) is set below the system's high-pressure protection switch activation value, leaving a safety margin. The temperature safety threshold (T_max) is set according to the compressor lubricating oil's tolerance temperature and safety standards (e.g., 120°C). The trigger condition is that either the pressure exceeds the pressure safety threshold or the temperature exceeds the temperature safety threshold, which triggers the safety protection. Once triggered, the control unit immediately overrides all other commands and sends a forced command to the drive unit to quickly reduce the dust cover area (usually by directly retracting it to a fully exposed state).

[0071] In this embodiment of the invention, the operating pressure and exhaust temperature monitored by the pressure acquisition device (usually installed in the exhaust pipe) and the temperature acquisition device (installed in the exhaust pipe or compressor housing) are core parameters reflecting the thermodynamic load of the air conditioning refrigeration system and the working intensity of the compressor. Unrestricted by vibration signal analysis algorithms or specific fault modes (such as vane tapping), it can comprehensively and in real-time reflect, from the perspective of the overall system energy balance, any cause (including but not limited to excessive dust cover coverage) leading to poor heat dissipation and increased load.

[0072] If either the operating pressure or the exhaust temperature exceeds its corresponding preset safety threshold (which is typically slightly lower than the activation value of hardware protection or fuses), the control device will immediately interrupt any currently executing mode (whether noise reduction adjustment or in the process of reverting to its previous state) and forcibly issue a high-priority command to the drive unit to unconditionally and quickly reduce the area of ​​the dust cover covering the condenser. This action aims to rapidly reduce the system load and prevent the accident from escalating. It ensures that even if the main control logic for active noise reduction fails (e.g., a vibration sensor malfunction causing a continuous demand for increased coverage), or if unforeseen extreme operating conditions occur, the safety threshold effectively prevents serious malfunctions such as compressor overload damage, lubricant deterioration, and weld cracking before reaching a dangerous critical point.

[0073] Reference Figure 2 This diagram illustrates the structure of an outdoor unit of an air conditioner according to an embodiment of the present invention. Figure 2 As an outdoor unit structure for air conditioners, a rotating shaft is installed around the condenser of the outdoor unit. The rotating shaft is fixed on a bracket structure protruding from the bottom cover. A dustproof cloth is fixed on the rotating shaft. The dustproof cloth and the rotating shaft together constitute a dustproof cloth assembly.

[0074] In some embodiments, the dustproof cloth assembly 101 includes at least two rotating shafts 1011 mounted on an air conditioner outdoor unit and a dustproof cloth 1012; the beginning end of the dustproof cloth 1012 is fixed to and wound around the rotating shaft 1011, and the end end of the dustproof cloth 1012 is fixed to and wound around another rotating shaft 1011; the driving device includes a motor connected to the rotating shaft 1011; The control device 104 is used to control the forward and reverse rotation of the motor and drive the rotating shaft 1011 to retract or release the dustproof cloth 1012.

[0075] To achieve the core function of reducing airflow, the dustproof cloth needs to be made of a low-permeability, high-density material (such as coated waterproof canvas, high-strength polyester fabric, etc.) to ensure effective air resistance when covering the area. The mechanical structure is a three-axis roller shutter design. Rotary shaft A (rewind shaft) is directly connected to the motor and is responsible for winding the dustproof cloth. When rotating forward, it pulls the cloth back from shaft C, reducing the coverage area. Rotary shaft B (guide shaft) remains stationary, providing support and changing the direction of the cloth, ensuring the cloth covers the condenser smoothly. Rotary shaft C (storage / release shaft) is connected to another motor and may contain an internal spring mechanism. When rotating forward, it releases the stored dustproof cloth, increasing the coverage area; or it is responsible for smoothing the cloth when winding it up from shaft A.

[0076] The dustproof cloth assembly also includes guide rails for guiding the movement of the edges of the dustproof cloth, which are positioned along both sides of the dustproof cloth. This is crucial for ensuring the formation of a "sealed barrier" and preventing secondary noise from vibration. The edges of the dustproof cloth are embedded in the guide rail grooves, ensuring smooth movement and a tight fit against the side wall of the housing when closed, effectively sealing the surface.

[0077] The ends of shafts A and C are connected to the output shafts of stepper motors or servo motors. Stepper motors allow for precise step control, facilitating accurate positioning of the coverage area by controlling the number of control pulses. The dust cover assembly needs to integrate a position sensor (such as an encoder or Hall sensor mounted on the shaft). Its function is to provide real-time feedback to the control device on the actual position of the dust cover (e.g., percentage covered), achieving closed-loop control and preventing control failure due to slippage or jamming.

[0078] Fully retracted (0% coverage, default safe state): The dust cover is completely wrapped around the A-axis, fully exposing the condenser. This is suitable for normal, powerful cooling / heating operation of the air conditioner; system power-on initialization; and forced reset in case of a malfunction. Partial coverage (e.g., 30%-75% coverage, noise reduction mode): The dust cover is partially unfolded, precisely covering a portion of the condenser area. This is suitable when sensors detect low-frequency compressor noise, and the control device instructs the motor to unfold the cloth to the calculated target position, increasing air resistance to regulate system pressure and eliminate noise. Full coverage (100% coverage, anti-clogging mode): The dust cover is fully unfolded and tightly fitted to the casing via guide rails, completely covering the front of the condenser. This is suitable for situations where the air conditioner is not running for extended periods (e.g., at night, during seasonal changes); or when the ambient wind speed is extremely low. In this case, it functions as an automatically closing protective cover.

[0079] In this embodiment of the invention, the mechanism that enables continuously adjustable coverage area is a roller shutter-type mechanical transmission system. The core of the dustproof cloth assembly lies in the collaboration between at least two rotating shafts and a rectangular dustproof cloth. The dustproof cloth is fixed at its beginning and wound around one rotating shaft (storage shaft), and its end is fixed and wound around another rotating shaft (rewind shaft). This design utilizes the rotational motion of the shafts to convert into linear displacement of the dustproof cloth plane. The motor can control the amount of dustproof cloth transferred between the two shafts by directly driving one or both shafts to rotate forward and backward. When the motor drives the rewind shaft to rotate and rewind, the cloth moves from the storage shaft to the rewind shaft, reducing the coverage area on the condenser; conversely, when the storage shaft is released or the rewind shaft rotates in the opposite direction, the cloth unfolds from the rewind shaft to the storage shaft, increasing the coverage area.

[0080] This mechanism allows for continuous adjustment of the coverage area, providing crucial execution capabilities for subsequent closed-loop precision control based on vibration signals. The roll-up design offers reliable movement, low friction, and ease of control, making it ideal for operation in the long-term vibration and temperature cycling environment of air conditioner outdoor units. Furthermore, when not in use, the dust cover can be neatly wound and stored inside the roll, preventing accelerated aging, soiling, or accidental snagging on the condenser fins caused by prolonged exposure, thus improving durability and reliability.

[0081] In some embodiments, the dustproof cloth assembly 101 further includes a guide rail 1013 for guiding the movement of the dustproof cloth edge.

[0082] In this embodiment of the invention, the guide rail provides a rigid moving track for the two side edges of the flexible dustproof cloth, ensuring that the cloth always moves straight along a predetermined path during the unfolding and retraction process. This effectively prevents the cloth from drifting, twisting, wrinkling, or even jamming due to wind, gravity, or asynchronous transmission, ensuring smooth and precise adjustment. When the dustproof cloth moves to the fully covered position, its two side edges are constrained within the guide rail. The guide rail itself precisely matches the air conditioner outdoor unit casing, allowing the edges of the cloth to fit tightly against the side wall of the casing, thus forming a basically enclosed physical barrier in front of the condenser, significantly improving the effect of blocking insects, willow catkins, and fine dust. Without the guide rail, the dustproof cloth is only fixed at both ends, and its middle and sides are prone to flapping and fluttering under strong winds or vibrations, which may generate new noise and cannot achieve an effective seal.

[0083] In dynamic noise reduction mode, the guide rails ensure that the dustproof cloth accurately and repeatedly covers the same area each time, avoiding control oscillations or failures caused by positional uncertainties. Regarding safety and durability, the guide rails constrain the cloth's range of motion, significantly reducing the risk of accidental contact or scratching with the delicate internal condenser fins, thus protecting the core heat exchanger. Simultaneously, they reduce the cloth's vibration in the wind, decreasing material fatigue and wear, and extending mechanical life.

[0084] Reference Figure 3 The diagram shows a schematic of the dustproof cloth of an air conditioner dustproof cloth assembly according to an embodiment of the present invention. Figure 3This is a schematic diagram of a dustproof cloth. One end of the dustproof cloth is the rotating axis, and the other end is the cloth itself. The dustproof cloth is fixed to the rotating axis, the rotating axis is wound around shaft A, and the end of the cloth is wound around shaft C. A stepper motor drives shafts A and C. When A is driven, the dustproof cloth moves from position C to position A, gradually covering the outdoor unit condenser. When C is driven, the dustproof cloth moves from position A to position C, gradually exposing the outdoor unit condenser. In another embodiment of the invention, the rotating axis of the dustproof cloth can be wound around shaft C, and the end of the cloth can be wound around shaft A. When A is driven, the dustproof cloth moves from position C to position A, gradually exposing the outdoor unit condenser. When C is driven, the dustproof cloth moves from position A to position C, gradually covering the outdoor unit condenser. This embodiment of the invention does not limit the scope of the invention.

[0085] This invention discloses an air conditioner, its control method, and a storage medium. By adjusting the coverage area of ​​the dustproof cloth assembly on the condenser, the airflow through the condenser can be regulated, thereby reducing the airflow to increase the exhaust pressure. This suppresses fin vibration and noise caused by insufficient pressure, effectively solving the low-frequency noise problem under low-load conditions at night. It also helps reduce wear and extend the lifespan of core components. Driving the dustproof cloth to cover the condenser forms a physical airtight barrier, effectively preventing insects, fallen leaves, and dust from clogging the air conditioner's outdoor unit. This reduces the frequency and intensity of manual cleaning, lowers equipment maintenance costs, and helps maintain the air conditioner in a long-term, efficient, and stable operating state.
