Description

Technical Field

[0001] This disclosure relates to the field of air conditioning technology, and in particular to an air conditioning control method, device, air conditioner, storage medium and program product. Background Technology

[0002] During the long-term operation of household air conditioners, the air guide plate, as the core air outlet component that directly contacts the hot and cold air, is prone to bending and warping due to factors such as uneven local temperature rise, material creep, installation stress, and long-term aging. This can lead to air leakage at the air outlet, direct airflow, and turbulent air field, reducing air delivery comfort and affecting user experience. Summary of the Invention

[0003] To overcome the problems existing in the related technologies, this disclosure provides an air conditioning control method, device, air conditioner, storage medium and program product.

[0004] According to a first aspect of the present disclosure, an air conditioning control method is provided, comprising:

[0005] Obtain the current temperature of the air guide plate and the current bending amount of the air guide plate;

[0006] Based on the current temperature and the current bending amount, perform a preset adjustment operation on the air guide plate component.

[0007] In some embodiments, performing a preset air guide plate component adjustment operation based on the current temperature and the current bending amount includes:

[0008] In response to the current temperature being less than or equal to a first preset temperature threshold and the current bending amount being greater than a first preset bending threshold and less than or equal to a second preset bending threshold, a first target adjustment angle is determined based on the current bending amount, and an air guide plate angle adjustment operation is performed to adjust the air guide plate to the first target adjustment angle based on the current angle.

[0009] Specifically, for situations where the air guide plate's current temperature is within the normal range and only exhibits slight bending, a method of fine-tuning the air guide plate's angle is used to suppress deformation. This eliminates the need for additional correction actuators, resulting in low hardware costs. Furthermore, by calculating the target angle adjustment based on the current amount of bending, the adjustment precision is controllable, and the impact of angle fine-tuning on airflow pressure drop and air delivery noise is minimal. This allows for the correction of slight deformation of the air guide plate, maintaining its straightness and aerodynamic performance without sacrificing air conditioning energy efficiency or air delivery experience.

[0010] In some embodiments, performing a preset air guide plate component adjustment operation based on the current temperature and the current bending amount includes:

[0011] In response to the current temperature being greater than a first preset temperature threshold and less than or equal to a second preset temperature threshold, and the current bending amount being less than or equal to a second preset bending threshold, it is determined whether the current angle of the air guide plate meets the preset angle condition.

[0012] In response to the fact that the current angle of the air guide plate does not meet the preset angle condition, a second target adjustment angle is determined based on the current bending amount, and an air guide plate angle adjustment operation is performed to adjust the air guide plate to the second target adjustment angle based on the current angle;

[0013] In response to the current angle of the air guide plate satisfying the preset angle condition, a first preset gear is determined based on the current temperature, and a fan gear adjustment operation is performed to adjust the fan gear to the first preset gear.

[0014] Specifically, for mild temperature conditions where the temperature rises slightly and deformation is not yet significant, thermal deformation is mitigated primarily by adjusting the angle of the air guide vane, which has less impact on energy efficiency and noise. When the angle of the air guide vane reaches the preset limit or other conditions and cannot be adjusted further, the fan speed is then switched to enhance heat dissipation. This ensures the deformation suppression effect under mild temperature conditions while minimizing the negative impact of the adjustment action on the air conditioner's energy efficiency and airflow noise, achieving a balance between anti-deformation effect and user experience.

[0015] In some embodiments, performing a preset air guide plate component adjustment operation based on the current temperature and the current bending amount includes:

[0016] In response to the current temperature being greater than a second preset temperature threshold and less than or equal to a third preset temperature threshold and / or the current bending amount being greater than a second preset bending threshold and less than a third preset bending threshold, it is determined whether a target correction actuator exists.

[0017] In response to the presence of the target correction actuator, a correction command is generated based on the current bending amount, and a correction operation is performed based on the correction command, so that the target correction actuator corrects the air guide plate according to the correction command;

[0018] In response to the absence of the target correction actuator, a first preset operation is performed.

[0019] Specifically, for overheating conditions with high temperatures or moderate deformation, products equipped with correction actuators apply a correction force directly to the air guide vanes via the actuators. For low-cost products without actuators, deformation is indirectly suppressed through pneumatic combination operations. Therefore, it can adapt to different hardware configurations and is compatible with air conditioning products of different positioning, improving the system's versatility and hardware adaptability.

[0020] In some embodiments, performing the first preset operation includes:

[0021] Adjust the fan speed to the second preset speed;

[0022] In response to the current static pressure difference being less than a preset static pressure difference threshold, the air guide plate is adjusted to a first preset angle based on the current angle and / or the swing mode of the air guide vane is adjusted to a dispersed air supply mode.

[0023] In response to the current bending amount being greater than a first preset bending threshold, the speed of the fan is adjusted to a third preset speed; the second preset speed is less than the third preset speed.

[0024] Specifically, without a calibration actuator, the system first accelerates airflow circulation by increasing the fan speed, quickly removing localized heat from the air guide plate to alleviate thermal stress. Simultaneously, the air guide angle and delivery mode are adjusted using static pressure difference as a constraint to prevent excessive wind resistance and increased energy consumption caused by control actions. Furthermore, the fan speed is increased in stages according to the degree of deformation, achieving a precise match between adjustment force and deformation risk. Therefore, without additional hardware, the system effectively improves the suppression of moderate to severe deformation of the air guide plate.

[0025] In some embodiments, performing a preset air guide plate component adjustment operation based on the current temperature and the current bending amount includes:

[0026] In response to the current temperature being greater than a third preset temperature threshold and / or the current bending amount being greater than or equal to a third preset bending threshold, a second preset operation is performed;

[0027] In response to the presence of a target correction actuator, the target correction actuator is controlled to adjust to a preset state.

[0028] Specifically, for extreme operating conditions where the temperature far exceeds the threshold or deformation is severe, a second preset operation is used to quickly cool down and suppress deformation, prioritizing the prevention of irreversible permanent deformation of the air guide plate. Furthermore, limit protection is provided for the correction actuator to prevent large actuator movements from exacerbating structural stress and causing component damage, thereby effectively extending the service life of the air guide plate and actuator components, and improving the structural reliability of the air conditioner under extreme operating scenarios.

[0029] In some embodiments, performing the second preset operation includes:

[0030] Adjust the fan speed to the fourth preset speed;

[0031] Alternatively, the fan can be controlled to operate intermittently according to a preset running time;

[0032] And / or adjust the angle of the air guide plate to the second preset angle;

[0033] And / or adjust the oscillation mode of the air guide vanes to a distributed air supply mode.

[0034] Specifically, by combining multiple methods such as low-speed continuous heat dissipation, intermittent cooling operation, angle adjustment, and decentralized airflow, the localized heat concentration effect of the air guide plate can be quickly reduced, preventing further deformation from the heat source. The intermittent operation and low-speed design balance heat dissipation efficiency with energy consumption control. Decentralized airflow avoids continuous impact of hot airflow on localized areas of the air guide plate. Therefore, the possibility of irreversible deformation is reduced even under extreme operating conditions.

[0035] In some embodiments, after performing a preset air guide plate component adjustment operation based on the current temperature and the current bending amount, the method further includes:

[0036] Obtain the current static pressure difference and current wind field uniformity data;

[0037] In response to the current static pressure difference being greater than a preset static pressure difference threshold and / or the current wind field uniformity data being greater than a preset wind field uniformity threshold, a rollback operation is performed to roll back the preset wind guide plate component adjustment operation.

[0038] Specifically, by using the real-time static pressure difference and wind field uniformity as hard constraints for the control action, the aerodynamic performance indicators are automatically checked after the anti-deformation adjustment is performed. Once the indicators exceed the limits, the operation is immediately triggered to back off, ensuring that the anti-deformation function always operates within the allowable range of energy efficiency, noise, and air supply comfort, taking into account both structural reliability and user experience.

[0039] In some embodiments, obtaining the current bending amount of the air guide plate includes:

[0040] In response to the fact that the air conditioner is equipped with a displacement sensor, the bending displacement value measured by the displacement sensor is determined as the current bending amount;

[0041] In response to the absence of the displacement sensor in the air conditioner, the current bending amount is determined using the preset bending amount estimation model.

[0042] Specifically, by constructing a multi-mode compatible bending measurement system, a high-precision solution can be used to directly measure the bending amount through displacement sensors, or a preset bending amount estimation model can be used to estimate the bending amount, which can be adapted to product configurations of different cost levels.

[0043] In some embodiments, it also includes:

[0044] In response to the air conditioner being equipped with the displacement sensor, the residual between the measured bending displacement value and the estimated bending amount is calculated;

[0045] In response to the residual being greater than a preset residual threshold and the number of consecutive times the residual is greater than or equal to a preset number, the displacement sensor is marked as abnormal, and the system automatically switches to a sensorless mode, using the preset bending amount estimation model to determine the current bending amount.

[0046] Specifically, the residual monitoring mechanism enables automatic identification of sensor faults and seamlessly switches to a degraded mode of model estimation when a sensor malfunctions, ensuring the continuous operation of the control logic without manual intervention.

[0047] According to a second aspect of the present disclosure, an air conditioning control device is provided, comprising:

[0048] The acquisition module is used to acquire the current temperature of the air guide plate and the current bending amount of the air guide plate;

[0049] The execution module is used to perform a preset adjustment operation on the air guide plate component based on the current temperature and the current bending amount.

[0050] According to a third aspect of the present disclosure, an air conditioner is provided, comprising:

[0051] processor;

[0052] Memory used to store processor-executable instructions;

[0053] The processor is configured to execute the air conditioning control method as described in the first aspect.

[0054] According to a fourth aspect of the present disclosure, a computer-readable storage medium is provided, the computer-readable storage medium storing computer-executable instructions, which, when executed by the computer, are used to implement the steps of the air conditioning control method provided in the first aspect.

[0055] According to a fifth aspect of the present disclosure, a computer program product is provided, including a computer program that, when executed, implements the air conditioning control method provided in the first aspect.

[0056] The embodiments of this disclosure provide an air conditioning control method, device, air conditioner, storage medium, and program product. By synchronously acquiring the temperature and deformation states of the air guide plate, targeted adjustment operations are performed on the air guide plate components based on the real-time operating status, achieving proactive closed-loop control of thermally induced deformation of the air guide plate. Compared to fixed structure or single-parameter control, by precisely matching the adjustment intensity according to the actual degree of deformation and heat load, energy efficiency loss caused by over-adjustment can be avoided, and the effectiveness of deformation suppression can be guaranteed, thereby improving the morphological stability and air delivery reliability of the air guide plate.

In the embodiments of this disclosure, these operations or steps may be performed serially; they may be performed in parallel; or a portion of these operations or steps may be performed.

[0072] In current technologies, during the long-term operation of household air conditioners, the air guide plate, as the core air outlet component that directly contacts the hot and cold air, is prone to bending and warping deformation due to factors such as uneven local temperature rise, material creep, installation stress, and long-term aging. This can lead to air leakage at the air outlet, direct airflow, and turbulent air field, reducing air delivery comfort and affecting user experience.

[0073] To address the aforementioned technical problems, this disclosure provides an air conditioning control method, device, air conditioner, storage medium, and program product. By synchronously acquiring the temperature and deformation states of the air guide plate, targeted adjustment operations are performed on the air guide plate components based on the real-time operating status, achieving proactive closed-loop control of thermally induced deformation of the air guide plate. Compared to fixed structure or single-parameter control, by precisely matching the adjustment intensity according to the actual degree of deformation and heat load, energy efficiency losses caused by over-adjustment can be avoided, and the effectiveness of deformation suppression can be guaranteed, thereby improving the morphological stability and air delivery reliability of the air guide plate.

[0074] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0075] Figure 1 This is a flow chart of an air conditioning control method shown according to some embodiments of the present disclosure. Figure 1 ,like Figure 1 As shown, it includes the following steps:

[0076] S11: Get the current temperature and current bending amount of the air guide plate.

[0077] In this application embodiment, the executing entity can be a processor. The processor can be a control unit installed inside the indoor unit of the air conditioner, used to receive sensor signals, process operating data, and output control commands to regulate the operating status of the air guide vane and the fan. Alternatively, the executing entity can be an air conditioning control device installed within the processor. This air conditioning control device can be implemented through software or a combination of software and hardware.

[0078] The air guide plate is an airflow guiding component at the air outlet of the indoor unit of the air conditioner, used to adjust the direction and range of air supply. Under heating or cooling conditions, the air guide plate is prone to deformation such as bending and warping due to uneven local temperature distribution and differences in thermal expansion and contraction of materials. This can lead to uneven gaps between air outlets, increased air supply resistance, and increased noise, affecting the energy efficiency of the air conditioner and user comfort.

[0079] The current temperature of the air guide plate is a characteristic temperature value that characterizes the overall heat load state of the air guide plate, and can be obtained through the temperature acquisition unit arranged on the air guide plate.

[0080] Optionally, multiple temperature sensors, such as NTC thermistors, can be arranged on the surface of the air guide plate. These sensors can be installed at various locations, including the air outlet side of the air guide plate near the indoor heat exchanger, the middle of the air guide plate along its length, and both end edges. After reading the collected values ​​from all temperature sensors, the processor can calculate the current temperature by taking the maximum value or using a weighted average.

[0081] If no displacement sensor is installed, the highest temperature is used as the current temperature. If a displacement sensor is installed, a weighted average method can be used to calculate the current temperature.

[0082] For example, the maximum value among multiple collected values ​​is taken as the current temperature, and the local highest temperature represents the maximum deformation risk. Alternatively, a weighted average temperature can be calculated as the current temperature based on preset weights for the influence of each location on deformation.

[0083] Among them, the current bending amount of the air guide plate is a quantitative parameter characterizing the degree of deformation of the air guide plate, which can be obtained by direct measurement or indirect estimation.

[0084] For example, if the air conditioner is equipped with a displacement sensor or strain sensor, the bending displacement value of the air guide plate can be directly measured by the sensor as the current bending amount. For instance, a Hall sensor and a matching magnet can be placed at the midpoint (the position of maximum deformation) along the length of the air guide plate, and the bending displacement can be obtained by detecting the change in distance between the air guide plate and the fixed housing. Alternatively, strain gauges can be attached to the surface of the air guide plate, and the bending amount can be calculated from the strain value.

[0085] For example, if the air conditioner is not equipped with a dedicated deformation detection sensor, the current bending amount can be estimated by using a pre-calibrated preset bending amount estimation model, combined with the current temperature and temperature distribution parameters of the air guide plate. The preset bending amount estimation model can be obtained by fitting a laboratory prototype test. The input parameters include the average temperature of the air guide plate, temperature gradient, etc., and the output is the corresponding estimated bending amount.

[0086] S12: Based on the current temperature and current bending amount, perform preset air guide plate component adjustment operations.

[0087] Among them, the preset air guide plate component adjustment operation is a set of adjustment actions pre-stored in the processor, adapted to different temperature levels and deformation levels. The adjustment objects include, but are not limited to, the angle of the air guide plate itself, the operating level of the indoor fan, the air delivery mode of the air guide blades, and the working status of the calibration actuator. Its core function is to suppress or correct the thermal deformation of the air guide plate.

[0088] Specifically, in this embodiment, the processor pre-stores multiple temperature threshold ranges and multiple bending amount threshold ranges. Based on the temperature range to which the current temperature belongs and the deformation range to which the current bending amount belongs, it matches the corresponding intensity of the adjustment operation and executes the preset adjustment operation for the air guide plate component. The higher the current temperature and the greater the current bending amount of the air guide plate, the higher the intensity of the corresponding adjustment operation, thereby achieving a precise match between deformation risk and adjustment force, avoiding under-adjustment or over-adjustment.

[0089] Optionally, in this embodiment, the processor, triggered periodically, acquires the current temperature and current bending amount within one control cycle and executes a preset adjustment operation for the air guide plate component.

[0090] Optionally, the control cycle time is preset.

[0091] For example, when the current temperature of the air guide plate is within the normal temperature range and the current bending amount is within the mild deformation range, a light adjustment operation is performed, which only slightly adjusts the angle of the air guide plate to change the airflow impact position and alleviate local thermal stress. When the current temperature of the air guide plate is within the medium-high temperature range and the current bending amount is within the moderate deformation range, a stronger adjustment operation is performed, which combines increasing the fan speed and adjusting the air guide angle to accelerate heat dissipation, or drives the correction actuator to apply a correction force to the air guide plate to restore its straight state. When the current temperature of the air guide plate exceeds the safe temperature threshold, or the current bending amount is close to the upper limit of deformation, a protective adjustment operation is performed, which quickly cools down the air guide plate through intermittent operation, dispersed air supply, etc., to prevent irreversible deformation of the air guide plate.

[0092] Optionally, all preset air guide vane component adjustment operations are subject to aerodynamic performance constraints, including static pressure difference constraints and airflow uniformity constraints. After executing the preset air guide vane component adjustment operation, the processor monitors the static pressure difference and airflow uniformity of the current airflow in real time. If the indicators exceed the preset threshold, the adjustment action is automatically reversed to avoid deformation-preventing operations that could lead to decreased air conditioning energy efficiency, increased airflow noise, or deterioration of comfort.

[0093] Specifically, by synchronously acquiring the temperature and deformation status of the air guide plate, targeted adjustments are made to the air guide plate components based on the real-time operating status, achieving proactive closed-loop control of thermally induced deformation of the air guide plate. Compared to fixed structure or single-parameter control, by precisely matching the adjustment intensity according to the actual degree of deformation and heat load, energy efficiency loss caused by over-adjustment can be avoided, and the effectiveness of deformation suppression can be guaranteed, thereby improving the morphological stability of the air guide plate and the reliability of air delivery.

[0094] Figure 2 This is a flow chart of an air conditioning control method shown according to some embodiments of the present disclosure. Figure 2 ,like Figure 2 As shown. As an optional implementation, based on the above embodiment, a preset air guide plate component adjustment operation is performed according to the current temperature and current bending amount, specifically including the following steps:

[0095] S21: In response to the current temperature being less than or equal to a first preset temperature threshold and the current bending amount being greater than a first preset bending threshold and less than or equal to a second preset bending threshold, a first target adjustment angle is determined based on the current bending amount, and an air guide plate angle adjustment operation is performed to adjust the air guide plate to the first target adjustment angle based on the current angle.

[0096] The first preset temperature threshold is pre-set and can be set independently according to needs.

[0097] For example, in a heating operation scenario, the first preset temperature threshold can be 40°C. When the current temperature of the air guide plate does not exceed this threshold, it means that the overall heating degree of the air guide plate is low, the thermal stress is within a controllable range, and the risk of severe deformation is low.

[0098] The first preset bending threshold is less than the second preset bending threshold. Both the first and second preset bending thresholds are pre-set and can be customized as needed.

[0099] Understandably, the first preset bending threshold represents the maximum allowable bending amount of the air guide plate while ensuring air delivery performance, appearance, and reliability requirements. The second preset bending threshold is a warning bending threshold, used to indicate that the air guide plate has not yet reached the upper limit of severe deformation.

[0100] It is understood that the operating condition corresponding to this embodiment is that the air guide plate is heated to a low degree and only undergoes slight elastic deformation. There is no need to start strong intervention measures such as fan speed regulation or actuator correction. The deformation can be alleviated and corrected by simply adjusting the angle of the air guide plate, so as to minimize the impact of adjustment on the normal operation of the air conditioner.

[0101] Specifically, the adjustment angle of the first target can be calculated using a preset angle calculation formula, as shown below:

[0102]

[0103] in, The preset angle adjustment ratio coefficient, The preset target bending amount. This represents the current bending amount.

[0104] Optionally, The corresponding value is preset.

[0105] For example, The value can be 0, or a value less than the first preset bending threshold.

[0106] The angle adjustment direction of the air guide plate corresponds to and matches the deformation direction. If, under heating conditions, the air guide plate undergoes outward bending deformation due to the higher heating degree on the inner side compared to the outer side, the processor controls the air guide plate to finely adjust its angle in the closing direction, changing the scouring area and pressure distribution of the airflow on the surface of the air guide plate, balancing the temperature difference and thermal stress on both sides of the air guide plate, thereby gradually suppressing and restoring the slight bending deformation.

[0107] For example, in this embodiment, in the air conditioning heating operation scenario, the first preset temperature threshold is 40℃, the first preset bending threshold is 0.5mm, the second preset bending threshold is 1.5mm, the target bending amount is 0.3mm, and the preset angle adjustment ratio coefficient is 2. If the processor detects that the current temperature of the air guide plate is 36℃ and the current bending amount is 1.0mm, it determines that the current temperature is less than or equal to the first preset temperature threshold and the current bending amount is greater than the first preset bending threshold and less than or equal to the second preset bending threshold. Therefore, the current bending amount is substituted into the preset angle calculation formula to determine the first target adjustment angle, thereby calculating the first target adjustment angle as -1.4 degrees. The negative sign represents adjustment in the closed direction. The processor drives the stepper motor of the air guide plate to rotate 1.4 degrees in the closed direction based on the current operating angle, completing the angle adjustment operation.

[0108] Specifically, for situations where the air guide plate's current temperature is within the normal range and only exhibits slight bending, a method of fine-tuning the air guide plate's angle is used to suppress deformation. This eliminates the need for additional correction actuators, resulting in low hardware costs. Furthermore, by calculating the target angle adjustment based on the current amount of bending, the adjustment precision is controllable, and the impact of angle fine-tuning on airflow pressure drop and air delivery noise is minimal. This allows for the correction of slight deformation of the air guide plate, maintaining its straightness and aerodynamic performance without sacrificing air conditioning energy efficiency or air delivery experience.

[0109] Figure 3 This is a flow chart of an air conditioning control method shown according to some embodiments of the present disclosure. Figure 3 ,like Figure 3As shown. As an optional implementation, based on any of the above embodiments, a preset air guide plate component adjustment operation is performed according to the current temperature and current bending amount, specifically including the following steps:

[0110] S31. In response to the current temperature being greater than the first preset temperature threshold and less than or equal to the second preset temperature threshold, and the current bending amount being less than or equal to the second preset bending threshold, determine whether the current angle of the air guide plate meets the preset angle condition.

[0111] The second preset temperature threshold is pre-set and is greater than the first preset temperature threshold.

[0112] For example, in a heating operation scenario, the second preset temperature threshold can be set to 50°C. When the current temperature of the air guide plate is between 40°C and 50°C, it indicates that the air guide plate is being heated more, thermal stress is accumulating continuously, and the deformation rate is accelerating. It is necessary to appropriately strengthen the intervention on the basis of slight adjustment, but it has not yet reached the overheating condition that requires strong correction.

[0113] The preset angle condition is used to determine whether the air guide plate has room for further adjustment. It can be preset according to the mechanical structure limit and aerodynamic performance constraint threshold of the air guide plate.

[0114] Optionally, the preset angle conditions include, but are not limited to, the current angle of the air guide plate having reached the mechanical limit angle in the corresponding direction, or the continued adjustment of the angle causing the static pressure difference in the air path to exceed the preset safety threshold.

[0115] Specifically, in this embodiment, the processor obtains the current position information of the current air guide plate and determines whether the current angle of the current air guide plate meets the preset angle condition.

[0116] S32. In response to the fact that the current angle of the air guide plate does not meet the preset angle condition, a second target adjustment angle is determined based on the current bending amount, and the air guide plate angle adjustment operation is performed to adjust the air guide plate to the second target adjustment angle based on the current angle.

[0117] Specifically, in this embodiment, when the current angle of the air guide plate does not meet the preset angle condition, the second target adjustment angle is calculated based on the current bending amount using the preset angle calculation formula, and the air guide plate angle adjustment operation is performed to adjust the air guide plate to the second target adjustment angle based on the current angle.

[0118] S33. In response to the current angle of the air guide plate meeting the preset angle condition, the first preset gear is determined based on the current temperature, and the fan gear adjustment operation is performed to adjust the fan gear to the first preset gear.

[0119] Specifically, when the current angle of the air guide plate meets the preset angle condition and there is no room for further adjustment, the processor determines the first preset gear based on the difference between the current temperature and the first preset temperature threshold, and performs a fan gear adjustment operation to adjust the fan gear to the first preset gear.

[0120] It is understandable that by increasing the operating speed of the indoor fan, the airflow circulation speed at the air outlet is accelerated, the heat on the surface of the air guide plate is quickly removed, and the overall temperature and local temperature gradient of the air guide plate are reduced, thereby inhibiting the further development of thermal deformation.

[0121] Specifically, the gear position can be calculated using a preset gear position calculation formula, as shown below:

[0122]

[0123] in, This is the preset gear adjustment ratio coefficient. This is the current temperature. This is the preset temperature threshold. This is the calculated gear mapping value.

[0124] Specifically, in this embodiment, the processor can substitute the current temperature into the preset gear calculation formula to calculate the gear mapping value corresponding to the current temperature. The processor compares the calculated gear mapping value with the preset gear mapping value and gear mapping relationship table to determine which gear mapping value range the current gear mapping value belongs to, thereby determining the number of gears to be increased. The processor then increases the fan by the corresponding number of gears based on the current gear, thereby adjusting it to the first preset gear.

[0125] The first preset gear can be obtained by increasing the current gear by 1 or 2 gears, but it shall not exceed the highest rated gear of the fan.

[0126] The preset gear mapping value and gear mapping relationship table stores the mapping relationship between preset gear mapping value ranges and corresponding gears. For example, if the gear mapping value range is between 10 and 20, then the gear is shifted up by 1 gear.

[0127] Optionally, in this embodiment, the processor can substitute the current temperature into the preset gear calculation formula to calculate the gear mapping value corresponding to the current temperature, compare the currently calculated gear mapping value with the preset gear threshold, determine the number of gears to be increased, and increase the fan by the corresponding number of gears based on the current gear.

[0128] For example, if the gear mapping value is less than or equal to the first gear threshold, the current fan gear remains unchanged. If the gear mapping value is greater than or equal to the first gear threshold and less than or equal to the second gear threshold, the fan gear is increased by 1 gear. The fan is then increased by the corresponding number of gears from its current gear, thereby adjusting it to the first preset gear.

[0129] Optionally, the first gear threshold and the second gear threshold are preset.

[0130] Specifically, for mild temperature conditions where the temperature rises slightly and deformation is not yet significant, thermal deformation is mitigated primarily by adjusting the angle of the air guide vane, which has less impact on energy efficiency and noise. When the angle of the air guide vane reaches the preset limit or other conditions and cannot be adjusted further, the fan speed is then switched to enhance heat dissipation. This ensures the deformation suppression effect under mild temperature conditions while minimizing the negative impact of the adjustment action on the air conditioner's energy efficiency and airflow noise, achieving a balance between anti-deformation effect and user experience.

[0131] Figure 4 This is a flow chart of an air conditioning control method shown according to some embodiments of the present disclosure. Figure 4 ,like Figure 4 As shown, as an optional implementation, based on any of the above embodiments, when performing a preset air guide plate component adjustment operation according to the current temperature and the current bending amount, the specific steps include:

[0132] S41. In response to the current temperature being greater than the second preset temperature threshold and less than or equal to the third preset temperature threshold and / or the current bending amount being greater than the second preset bending threshold and less than the third preset bending threshold, determine whether a target correction actuator exists.

[0133] It is understandable that the core objective of this embodiment, which corresponds to the overheating and strengthening adjustment condition of the air guide plate, is to quickly reduce the local temperature rise of the air guide plate, directly correct the bending deformation, and prevent the deformation from further aggravating and entering an irreversible extreme state.

[0134] The third preset temperature threshold is pre-set.

[0135] It is understandable that the third preset temperature threshold is a critical temperature threshold. If the third preset temperature threshold is exceeded, it can be considered that the air guide plate has a significant risk of instability or irreversible deformation.

[0136] The second preset bending threshold and the third preset bending threshold are preset.

[0137] For example, in a heating operation scenario, the second preset temperature threshold is set to 50°C, and the third preset temperature threshold is set to 60°C.

[0138] The target correction actuator is a drive component used to apply active correction force to the air guide plate and directly counteract thermal bending deformation. It can be a low-profile actuator such as shape memory alloy (SMA) wire or thin stepper motor, and is installed at the pivot point of the air guide plate or in the stress concentration area of ​​its inner surface. After being powered on or started, it can drive the air guide plate back to a straight state through actions such as contraction and pushing.

[0139] Specifically, in this embodiment, the processor determines whether a target correction actuator exists inside the air conditioner when the current temperature is greater than the second preset temperature threshold and less than or equal to the third preset temperature threshold and / or the current bending amount is greater than the second preset bending threshold and less than the third preset bending threshold.

[0140] S42. In response to the presence of a target correction actuator, generate a correction command based on the current bending amount, and perform a correction operation based on the correction command, so that the target correction actuator corrects the air guide plate according to the correction command.

[0141] Specifically, the current bending amount can be calculated using a preset formula for the corrective actuator, as shown below:

[0142]

[0143] in, This is the actuator compensation proportional coefficient. The preset target bending amount. This represents the current bending amount. To correct the output of the actuator instruction.

[0144] Specifically, in this embodiment, the processor calculates the actuator correction command output by substituting the current bending amount into the preset correction actuator calculation formula, generates a correction command based on the actuator correction command output, drives the target correction actuator to act, and directly applies a reverse correction force to the air guide plate.

[0145] S43. In response to the absence of a target correction actuator, perform the first preset operation.

[0146] Specifically, in this embodiment, if the processor determines that there is no target correction actuator in the air conditioner, it performs the first preset operation.

[0147] Optionally, the first preset operation includes, but is not limited to, adjusting the fan speed and adjusting the air supply mode.

[0148] Specifically, for overheating conditions with high temperatures or moderate deformation, products equipped with correction actuators apply a correction force directly to the air guide vanes via the actuators. For low-cost products without actuators, deformation is indirectly suppressed through pneumatic combination operations. Therefore, it can adapt to different hardware configurations and is compatible with air conditioning products of different positioning, improving the system's versatility and hardware adaptability.

[0149] As an optional implementation, based on any of the above embodiments, a first preset operation is performed, including:

[0150] Adjust the fan speed to the second preset speed;

[0151] In response to the current static pressure difference being less than the preset static pressure difference threshold, the air guide plate is adjusted to a first preset angle based on the current angle and / or the swing mode of the air guide vane is adjusted to a decentralized air supply mode.

[0152] In response to the current bending amount exceeding the first preset bending threshold, the fan speed is adjusted to the third preset speed.

[0153] The second preset gear is smaller than the third preset gear.

[0154] The second preset gear is the target gear after the current fan gear is increased by 1 gear, and does not exceed the highest rated gear of the fan.

[0155] The third preset gear is the target gear after increasing the current gear by 2 gears, and does not exceed the highest rated gear of the fan.

[0156] Specifically, in this embodiment, in response to the current temperature being greater than a second preset temperature threshold and less than or equal to a third preset temperature threshold and / or the current bending amount being greater than a second preset bending threshold and less than a third preset bending threshold, and determining that there is no target correction actuator in the air conditioner, the processor increases the air conditioner's fan speed by one level, adjusting it to the second preset speed. After executing the adjustment to the second preset speed, the controller immediately obtains the current static pressure difference and performs a rapid safety check. If the current static pressure difference is less than a preset static pressure difference threshold, the processor can choose to execute any of the following adjustment methods, or execute the following operations simultaneously. The processor adjusts the air guide vane to a second preset angle in the closing direction based on the current angle. By reducing the airflow angle of attack of the air guide vane, the direct impact intensity of the hot airflow on the inner surface of the air guide vane is reduced. At the same time, the airflow path is optimized, reducing local airflow blockage, alleviating thermal deformation while avoiding a significant increase in pressure drop. The swing mode of the air guide vane can also be adjusted from the current mode to a decentralized air supply mode. In the decentralized air supply mode, the louvers change the airflow from centralized guidance to multi-directional uniform diffusion, avoiding the continuous flow of hot air scouring the same local area of ​​the air guide plate and alleviating local thermal stress concentration.

[0157] Furthermore, in this embodiment, if after the processor performs the above operation, after running for a preset time, and determines that the current static pressure difference is less than the preset static pressure difference threshold and the current wind field uniformity data is less than the preset wind field uniformity threshold, the current bending amount is re-acquired. If the re-acquired current bending amount is greater than the first preset bending threshold, the fan speed is increased to the third preset speed.

[0158] The preset time is a pre-set time, which is less than the control cycle.

[0159] For example, the control cycle is 5 minutes, the preset time is 1 minute, and within one control cycle.

[0160] Understandably, the oscillation mode of the air guide vanes is being adjusted from the current mode to a distributed air supply mode. In the distributed air supply mode, the vanes change the airflow from centralized guidance to multi-directional uniform diffusion, avoiding continuous hot airflow washing over the same local area of ​​the air guide plate and alleviating localized thermal stress concentration.

[0161] Understandably, if the current static pressure difference is greater than or equal to the preset static pressure difference threshold, it means that the current wind resistance is close to the upper limit of energy efficiency, and no further angle and sway blade adjustment actions will be added to avoid further increase in pressure drop.

[0162] The current static pressure difference can be collected in real time by differential pressure sensors placed at the fan outlet and the indoor environment side. Alternatively, it can be calculated by looking up a table based on a pre-calibrated mapping relationship between fan speed, fan current, air guide angle, and pressure drop.

[0163] Specifically, without a calibration actuator, the system first accelerates airflow circulation by increasing the fan speed, quickly removing localized heat from the air guide plate to alleviate thermal stress. Simultaneously, the air guide angle and delivery mode are adjusted using static pressure difference as a constraint to prevent excessive wind resistance and increased energy consumption caused by control actions. Furthermore, the fan speed is increased in stages according to the degree of deformation, achieving a precise match between adjustment force and deformation risk. Therefore, without additional hardware, the system effectively improves the suppression of moderate to severe deformation of the air guide plate.

[0164] Figure 5 This is a flow chart of an air conditioning control method shown according to some embodiments of the present disclosure. Figure 5 ,like Figure 5 As shown, as an optional implementation, based on any of the above embodiments, when performing a preset air guide plate component adjustment operation according to the current temperature and the current bending amount, the specific steps include:

[0165] S51: In response to the current temperature being greater than the third preset temperature threshold and / or the current bending amount being greater than or equal to the third preset bending threshold, execute the second preset operation.

[0166] It is understandable that the core control objective of this embodiment, which corresponds to the extreme protection condition of the air guide plate, is to prioritize the prevention of irreversible permanent thermal deformation of the air guide plate to ensure structural safety, while also taking into account the basic performance of the air conditioner operation.

[0167] Specifically, in this embodiment, the processor performs a second preset operation when the current temperature is greater than a third preset temperature threshold and / or the current bending amount is greater than or equal to a third preset bending threshold.

[0168] Optionally, the second preset operation includes, but is not limited to, adjusting the fan speed and adjusting the air guide plate mode.

[0169] Optionally, while executing the second preset operation, the processor triggers a fault recording and maintenance prompt mechanism. It will automatically collect and store complete diagnostic data under the current operating conditions, including information such as air guide plate temperature, bending amount, airflow pressure drop, actuator action records, and runtime. Simultaneously, maintenance prompts will be sent to the user through the air conditioner display panel and associated terminal applications, reminding them of the risk of abnormal high-temperature deformation and suggesting contacting professional testing to prevent further escalation of the fault. The complete diagnostic data can also be uploaded to the cloud for subsequent product optimization and fault analysis.

[0170] S52: In response to the presence of a target correction actuator, control the target correction actuator to adjust to a preset state.

[0171] Specifically, in this embodiment, when the air conditioner is equipped with a target correction actuator, the controller immediately controls the target correction actuator to adjust to a preset state when the current temperature is greater than a third preset temperature threshold and / or the current bending amount is greater than or equal to a third preset bending threshold.

[0172] Optionally, the preset state is the limiting protection state of the target correction actuator, including but not limited to stopping the large dynamic correction action of the target correction actuator, or controlling the target correction actuator to slowly reset to the initial position.

[0173] It is understandable that by adjusting the actuator to the preset state, the actuator can be prevented from forcibly applying a corrective force under the high temperature and high stress state of the air guide plate, which could lead to structural stress overload, air guide plate breakage, installation structure detachment, or damage to the actuator itself.

[0174] Specifically, for extreme operating conditions where the temperature far exceeds the threshold or deformation is severe, a second preset operation is used to quickly cool down and suppress deformation, prioritizing the prevention of irreversible permanent deformation of the air guide plate. Furthermore, limit protection is provided for the correction actuator to prevent large actuator movements from exacerbating structural stress and causing component damage, thereby effectively extending the service life of the air guide plate and actuator components, and improving the structural reliability of the air conditioner under extreme operating scenarios.

[0175] As an optional implementation, based on any of the above embodiments, a second preset operation is performed, including:

[0176] Adjust the fan speed to the fourth preset speed;

[0177] Alternatively, the fan can be controlled to operate intermittently according to a preset running time;

[0178] And / or adjust the angle of the air guide plate to the second preset angle;

[0179] And / or adjust the oscillation mode of the air guide vanes to a distributed air supply mode.

[0180] The fourth preset setting is the lowest setting of the air conditioner's corresponding fan speed.

[0181] Among them, the control fan operates intermittently according to a preset running time, which is a periodic start-stop cooling method, with fixed running time and stop time pre-configured.

[0182] For example, the fan is set to run for 30 seconds and stop for 30 seconds, and then the operation is repeated in a cycle of 30 seconds of air supply and 30 seconds of shutdown. Intermittent operation allows the air guide plate to fully dissipate heat and equalize the temperature field during the shutdown phase, effectively suppressing the continuous rise in temperature. This is preferably applied to scenarios where the air guide plate temperature exceeds the standard significantly and the temperature rise rate is rapid.

[0183] The second preset angle is the maximum opening angle of the air guide plate.

[0184] Understandably, by adjusting the air guide plate to the second preset angle, the airflow cross-sectional area is maximized, the airflow resistance is significantly reduced, and the hot airflow is prevented from continuously impacting the plate surface at close range when the air guide plate is at a small opening, thus reducing the accumulation of local thermal stress.

[0185] Among them, the decentralized air supply mode means that the air guide vanes no longer point to a fixed direction to deliver air, but instead swing back and forth within a preset angle range, breaking up the concentrated airflow into multi-directional diffused airflow, avoiding the long-term action of hot airflow on the same position of the air guide plate, and improving the temperature distribution throughout the area.

[0186] Specifically, when the current temperature is greater than the third preset temperature threshold and / or the current bending amount is greater than or equal to the third preset bending threshold, the processor can execute the operations in this embodiment individually or in combination, depending on the operating conditions of the air conditioner.

[0187] For example, under extreme protection conditions, the fan can be controlled to run intermittently for a preset operating time, adjusting the air guide vane angle to a second preset angle. Furthermore, if the processor determines that a target correction actuator is installed inside the air conditioner, the large-scale dynamic correction action of the target correction actuator is stopped. The processor continuously acquires the latest current temperature; if it determines that the current temperature is continuously rising, the fan speed is adjusted to a fourth preset speed. When acquiring the current temperature, if the processor finds that the temperature of any temperature sensor exceeds the corresponding temperature threshold, the oscillation mode of the air guide vanes is adjusted to a distributed airflow mode.

[0188] Specifically, by combining multiple methods such as low-speed continuous heat dissipation, intermittent cooling operation, angle adjustment, and decentralized airflow, the localized heat concentration effect of the air guide plate can be quickly reduced, preventing further deformation from the heat source. The intermittent operation and low-speed design balance heat dissipation efficiency with energy consumption control. Decentralized airflow avoids continuous impact of hot airflow on localized areas of the air guide plate. Therefore, the risk of irreversible deformation is reduced even under extreme operating conditions.

[0189] Figure 6 This is a flow chart of an air conditioning control method shown according to some embodiments of the present disclosure. Figure 6 ,like Figure 6 As shown, as an optional implementation, based on any of the above embodiments, after performing a preset adjustment operation on the air guide plate component according to the current temperature and the current bending amount, the specific steps include:

[0190] S61: Obtain the current static pressure difference and current wind field uniformity data.

[0191] Among them, the current static pressure difference refers to the real-time difference between the static air pressure at the fan outlet side and the static air pressure at the indoor environment side in the air supply path of the air conditioner indoor unit.

[0192] The current wind field uniformity data refers to the dispersion of the supply air velocity distribution at different points on the air outlet cross-section of the air conditioner. The current wind field uniformity data is real-time data.

[0193] The current static pressure difference can be obtained in the following ways: For models equipped with a differential pressure sensor, the static pressure difference between the fan outlet side and the indoor environment side is directly collected through the differential pressure sensor. For models without a differential pressure sensor, it is calculated by looking up a table based on a pre-calibrated mapping relationship between fan speed, fan current, air guide angle, and pressure drop.

[0194] The current wind field uniformity data can be obtained in the following ways: For models equipped with an outlet wind speed array sensor, the wind speed variance is calculated through multi-point wind speed sampling to obtain the real-time wind field uniformity. For models without the corresponding sensor, the corresponding value is estimated by calling a pre-calibrated wind field uniformity mapping model based on the current fan speed, guide vane angle, and blade air delivery mode parameters.

[0195] S62: In response to the current static pressure difference being greater than the preset static pressure difference threshold and / or the current wind field uniformity data being greater than the preset wind field uniformity threshold, a rollback operation is performed to roll back the preset wind guide plate component adjustment operation.

[0196] Specifically, in this embodiment, after each preset air guide plate component adjustment operation is performed based on the current temperature and the current bending amount, the processor immediately obtains the current static pressure difference and the current wind field uniformity data, compares the current static pressure difference with the preset static pressure difference threshold, and compares the current wind field uniformity data with the preset wind field uniformity threshold. When the processor detects that the current static pressure difference is greater than the preset static pressure difference threshold or the current wind field uniformity data is greater than the preset wind field uniformity threshold, it immediately performs a rollback operation, cancels the preset air guide plate component adjustment operation performed this time, and restores the operating state before the current adjustment.

[0197] Optionally, if multiple adjustment actions are performed simultaneously, the fan speed adjustment can be reversed first. If the index still exceeds the limit after reversal, the guide vane angle adjustment can be reversed, and finally the oscillating blade mode adjustment can be reversed, until the static pressure difference and wind field uniformity both meet the threshold requirements.

[0198] After executing the rollback operation, the controller automatically records the over-limit event, including data such as the current operating temperature, bending amount, executed adjustment action, and over-limit magnitude, and incorporates it into the self-learning dataset. During periodic parameter optimization, the controller adjusts relevant control gains based on this type of over-limit data, such as preset angle adjustment ratio coefficients and preset gear adjustment ratio coefficients, to prevent over-adjustment leading to performance over-limit issues in subsequent similar operating conditions.

[0199] If, after multiple consecutive rollbacks, the current static pressure difference and the current wind field uniformity data still fail to meet the constraint requirements, the controller triggers the fault diagnosis logic to check for abnormal operating conditions such as filter blockage, dust accumulation in the air duct, or obstruction of the air guide plate, and issues a cleaning and maintenance reminder to the user.

[0200] Specifically, by using the real-time static pressure difference and wind field uniformity as hard constraints for the control action, the aerodynamic performance indicators are automatically checked after the anti-deformation adjustment is performed. Once the indicators exceed the limits, the operation is immediately triggered to back off, ensuring that the anti-deformation function always operates within the allowable range of energy efficiency, noise, and air supply comfort, taking into account both structural reliability and user experience.

[0201] As an optional implementation, based on any of the above embodiments, obtaining the current bending amount of the air guide plate includes:

[0202] In response to the fact that the air conditioner is equipped with a displacement sensor, the bending displacement value measured by the displacement sensor is determined as the current bending amount;

[0203] Since the air conditioner is not equipped with a displacement sensor, the current bending amount is determined using a preset bending amount estimation model.

[0204] Specifically, in this embodiment, when the air conditioner is equipped with a displacement sensor, the processor can directly determine the bending displacement value measured by the displacement sensor as the current bending amount. When the air conditioner is not equipped with a displacement sensor, the current bending amount is calculated using a preset bending amount estimation model.

[0205] Optionally, the displacement sensor can be a Hall displacement sensor, fiber optic strain gauge, or PCB strain gauge, etc. It is preferably installed at the midpoint of the length direction of the air guide plate, which is the location of the largest thermal bending deformation, and can accurately collect the deflection displacement data of the air guide plate.

[0206] Specifically, the relationship corresponding to the preset bending amount estimation model is as follows:

[0207]

[0208] in, This is the average temperature collected by the temperature sensor on the air guide plate, used to represent the current overall heat load level of the air guide plate. This is the preset temperature. For temperature gradient. , and These are preset coefficients.

[0209] The preset temperature is a pre-set temperature.

[0210] The temperature gradient represents the degree of temperature difference dispersion between different locations on the air guide plate, such as the temperature difference between the middle and both ends, or between the windward and leeward sides.

[0211] The preset coefficient is a pre-set coefficient.

[0212] Specifically, by constructing a multi-mode compatible bending measurement system, a high-precision solution can be implemented through direct measurement using displacement sensors, while a pre-set bending estimation model can be used to estimate the bending amount, adapting to product configurations at different cost levels. Furthermore, a residual monitoring mechanism enables automatic identification of sensor faults, seamlessly switching to a degraded model estimation mode when a sensor malfunctions, ensuring continuous operation of the control logic without manual intervention.

[0213] As an optional implementation, based on any of the above embodiments, it further includes:

[0214] In response to the air conditioner being equipped with a displacement sensor, the residual between the measured bending displacement value and the estimated bending amount is calculated;

[0215] If the residual is greater than a preset residual threshold and the number of consecutive times the residual is greater than or equal to a preset number, the displacement sensor is marked as abnormal, and the system automatically switches to sensorless mode and uses a preset bending amount estimation model to determine the current bending amount.

[0216] Specifically, in this embodiment, for models equipped with displacement sensors, the processor synchronously calculates the residual between the measured bending displacement value and the model-estimated bending amount during operation. The residual is calculated using absolute values. When the residual is detected to be greater than a preset residual threshold, and this state occurs consecutively more than a preset number of times, it is determined that the displacement sensor is malfunctioning. The processor will no longer use the measured bending displacement value collected by the displacement sensor as the current bending amount, but will instead use a preset bending amount estimation model to determine the current bending amount.

[0217] Among them, the preset residual threshold and the preset number of times are preset.

[0218] For example, the residual threshold can be set to 0.3 mm, and the threshold for the number of consecutive exceedances can be set to 5 times.

[0219] The processor synchronously records the operating data when the displacement sensor malfunctions, including temperature, running time, residual change trend, etc., and sends maintenance prompts to users through the air conditioner display panel and associated terminal applications to remind users to check the displacement sensor.

[0220] Specifically, the residual monitoring mechanism enables automatic identification of sensor faults and seamlessly switches to a degraded mode of model estimation when a sensor malfunctions, ensuring the continuous operation of the control logic without manual intervention.

[0221] Figure 7 This is a block diagram of an air conditioning control device according to some embodiments of the present disclosure. (Refer to...) Figure 7 The device 70 includes an acquisition module 71 and an execution module 72.

[0229] Optionally, the acquisition module 71 is used to acquire the current static pressure difference and the current wind field uniformity data after performing a preset wind guide plate component adjustment operation based on the current temperature and the current bending amount. The execution module 72 is used to perform a rollback operation in response to the current static pressure difference being greater than a preset static pressure difference threshold and / or the current wind field uniformity data being greater than a preset wind field uniformity threshold, so as to roll back the executed preset wind guide plate component adjustment operation.

[0246] In the above detailed description, reference has been made to the accompanying drawings, which illustrate specific aspects of this disclosure by way of illustration. In this regard, terms indicating direction or positional relationship, such as “center,” “longitudinal,” “lateral,” “length,” “width,” “thickness,” “upper,” “lower,” “front,” “rear,” “left,” “right,” “vertical,” “horizontal,” “top,” “bottom,” “inner,” “outer,” “clockwise,” “counterclockwise,” “axial,” “radial,” and “circumferential,” are used with reference to the orientation of the described figures. Since components of the described device can be positioned in multiple different orientations, directional terms are used for illustrative purposes and not for limitation. It should be understood that other aspects can be utilized and structural or logical changes can be made without departing from the concept of this disclosure. Therefore, the following detailed description should not be considered limiting.

[0247] It should be understood that, unless otherwise specifically indicated, features of various embodiments of this disclosure described herein can be combined with each other. As used herein, the term “and / or” includes any one of the relevant listed items and any combination of any two or more; similarly, “at least one of…” includes any one of the relevant listed items and any combination of any two or more.

[0248] It should be understood that, unless otherwise expressly specified and limited, the terms "joining," "attaching," "installing," "connecting," "linking," "fixing," etc., used in the embodiments of this disclosure should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms herein based on the specific circumstances.

[0249] Furthermore, the term "above" as used herein with respect to components, elements, or material layers formed or located "above" a surface may be used to indicate that the component, element, or material layer is "indirectly" positioned (e.g., placed, formed, deposited, etc.) on the surface such that one or more additional components, elements, or layers are arranged between the surface and the component, element, or material layer. However, the term "above" as used with respect to components, elements, or material layers formed or located "above" a surface may also optionally have a specific meaning: that the component, element, or material layer is "directly" positioned (e.g., placed, formed, deposited, etc.) on the surface, for example, in direct contact with the surface.

[0250] Although terms such as “first,” “second,” and “third” may be used herein to describe various components, parts, regions, layers, or sections, these components, parts, regions, layers, or sections are not limited to these terms. Rather, these terms are used only to distinguish one component, part, region, layer, or section from another. Therefore, without departing from the teachings of the examples described herein, the first component, part, region, layer, or section mentioned in the examples may also be referred to as the second component, part, region, layer, or section. Furthermore, the terms “first” and “second” are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as “first” or “second” may explicitly or implicitly include at least one of that feature. In the description herein, “a plurality” means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0251] It should be understood that spatial relative terms, such as “above,” “upper,” “below,” and “lower,” are used herein to describe the relationship between one element and another shown in the figures. In addition to the orientation depicted in the figures, these spatial relative terms are also intended to encompass different orientations of the device in use or operation. For example, if the device in the figures is flipped, an element described as “above” or “upper” relative to another element would be “below” or “lower” relative to that other element. Thus, depending on the spatial orientation of the device, the term “above” encompasses both above and below orientations. Devices may have other orientations (e.g., rotated 90 degrees or in other orientations), and the spatial relative terms used herein should be interpreted accordingly.

[0252] Furthermore, the term “exemplary” is used herein to mean serving as an example, instance, or illustration. Any aspect or design described herein as “exemplary” is not necessarily to be construed as advantageous compared to other aspects or designs. Rather, the use of the term “exemplary” is intended to present the concept in a concrete manner. As used herein, the term “or” is intended to mean an inclusive “or” rather than an exclusive “or.” That is, unless otherwise specified or clear from the context, “X applies A or B” is intended to mean any of the natural inclusive arrangements. That is, “X applies A or B” satisfies any of the foregoing instances if X applies A; X applies B; or both X applies A and B. Additionally, unless otherwise specified or clear from the context to refer to the singular form, the articles “a” and “an” as used in this application and the appended claims are generally understood to mean “one or more.”

[0253] Similarly, although this disclosure has been shown and described with respect to one or more implementations, equivalent variations and modifications will occur to those skilled in the art upon reading and understanding this specification and the accompanying drawings. This disclosure includes all such modifications and variations and is limited only by the scope of the claims. In particular, with respect to the various functions performed by the components described above (e.g., elements, resources, etc.), unless otherwise indicated, the terminology used to describe such components is intended to correspond to any component (functionally equivalent) that performs the specific function of the described component, even if structurally not equivalent to the disclosed structure. Furthermore, although specific features of this disclosure may have been disclosed with respect to only one of several implementations, such features may be combined with one or more other features of other implementations, as may be desired and advantageous to any given or particular application. Moreover, with regard to the terms “comprising,” “owning,” “having,” “having,” or variations thereof as used in the detailed description or claims, such terms are intended to be inclusive in a manner similar to the term “including.”

[0254] Other embodiments of this disclosure will readily occur to those skilled in the art upon consideration of the specification and practice of the invention disclosed herein. This application is intended to cover any variations, uses, or adaptations of this disclosure that follow the general principles of this disclosure and include common knowledge or customary techniques in the art not disclosed herein. The specification and examples are to be considered exemplary only, and the true scope and spirit of this disclosure are indicated by the following claims.

[0255] It should be understood that this disclosure is not limited to the precise structures described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope. The scope of this disclosure is limited only by the appended claims.
