Description

Technical Field

[0001] This invention relates to air conditioning equipment, and more particularly to a silent air cooler and control method for realizing dynamic switching of electrode matrix. Background Technology

[0002] Silent air coolers utilize high voltage applied to positive and negative electrodes to generate airflow and create wind. Since there is no motor or fan blades, the airflow is gentle and quiet. Combined with the air source and airflow design, it can blow out a gentle cool breeze, allowing people to feel the freshness of natural wind, providing a comfortable experience and being more beneficial to their health.

[0003] However, existing silent air coolers often have relatively fixed electrode control methods in their design, with only one or a few fixed airflow adjustment levels, which cannot meet the diverse airflow needs of users. In addition, the motor's operating mode is relatively fixed, which can easily lead to decreased efficiency and reduced lifespan after long-term use. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of existing silent air coolers, which cannot meet the diverse wind speed requirements of users and are prone to decreased efficiency and reduced lifespan after long-term use. This invention provides a silent air cooler and control method that realizes dynamic switching of the electrode matrix.

[0005] The objective of this invention is achieved through the following technical solution: A silent air cooler that enables dynamic switching of the electrode matrix includes: A high-voltage generator is used to produce high voltage. The electrodes generate an electric field when activated, ionizing air molecules to form an ion wind; Several electrode layers, each electrode layer including several electrodes in the same plane, and all electrodes are arranged in space to form an electrode output matrix; The electrode output controller is used to apply high voltage to the electrodes and control the electrodes to turn on or off. The number of electrodes turned on in different electrode output matrices controls the air cooler to operate in different modes.

[0006] This design allows for flexible control of electrode opening and closing, enabling real-time adjustment of output power based on environmental or user needs. By controlling the number of electrodes open, stepless speed regulation can be achieved, breaking through the limitations of traditional gears. Simultaneously, the multi-layer electrode matrix can achieve three-dimensional airflow guidance, forming directional or diffused airflow, achieving precise airflow control.

[0007] Preferably, the number of electrode layers is not less than 4 layers, and the number of electrodes in different electrode layers is equal.

[0008] As a preferred option, the silent air cooler that enables dynamic switching of the electrode matrix also includes an airflow sensor to detect the airflow at the air outlet.

[0009] A control method for a silent air cooler that achieves dynamic switching of the electrode matrix, based on a silent air cooler that achieves dynamic switching of the electrode matrix, includes setting an accelerated airflow working mode, specifically: The system can be set to different speed-enhancing airflow modes, with the speed gradient increasing from low to high according to the speed level. In the low-speed acceleration airflow mode, fewer electrodes are activated in the electrode layer near the air outlet, while in the high-speed acceleration airflow mode, more electrodes are activated in the electrode layer near the air outlet. The number of electrodes activated in the electrode layer near the air outlet is always less than or equal to the number of electrodes activated in the electrode layer farther from the air outlet.

[0010] This design allows for different acceleration airflow modes to meet user needs in various scenarios. Adjusting the number of electrodes activated near and away from the air outlet based on the selected speed ensures a more even airflow distribution, preventing localized areas of excessive or insufficient airflow and improving both cooling and ventilation efficiency.

[0011] A control method for a silent air cooler that achieves dynamic switching of the electrode matrix is ​​disclosed. Based on a silent air cooler that achieves dynamic switching of the electrode matrix, an electrode even distribution working mode is set. In this mode, several different electrode output matrices are configured, and then the electrode matrix activation sequence is cyclically switched to balance the usage time of different electrodes. The cyclic switching process specifically involves: Step 1: Set a certain electrode output matrix as the initial electrode output matrix, and the electrode outputs according to the state of the initial electrode output matrix; Step 2: Set the corresponding switching target value, and switch to different electrode output matrices sequentially according to the activation sequence; Step 3: Compare the difference between the current electrode output matrix and the switching target value, identify the electrodes that need to be adjusted, and switch them accordingly. Step 4: Update the electrode output matrix and jump back to step 2.

[0012] This design uses a cyclic switching of the electrode matrix activation sequence to balance the usage time of different electrodes, preventing some electrodes from becoming excessively worn due to prolonged use, thereby extending the overall lifespan of the electrodes and reducing equipment maintenance costs.

[0013] Preferably, in step 3, the number of partial electrodes adjusted each time is less than or equal to 2.

[0014] This design allows for adjustments to only a small number of electrodes at a time, resulting in smoother airflow changes in the evaporative cooler. This avoids sudden and significant changes in airflow caused by adjusting too many electrodes at once, which could lead to an uncomfortable experience for the user.

[0015] Preferably, in step 3, after switching the electrodes, the air volume sensor detects the air volume at the air outlet and compares the detected air volume at the air outlet with a set threshold. If the detected air volume at the air outlet is within the set threshold, the process jumps to step 4. If the detected air volume at the air outlet is outside the set threshold, the electrodes are adjusted and the air volume at the air outlet is detected again until the air volume no longer exceeds the set threshold.

[0016] Preferably, the method for adjusting the electrodes is as follows: Set up a suppression control matrix and an enhancement control matrix. The suppression control matrix represents the electrodes that are allowed to be turned off and their turn-off sequence, while the enhancement control matrix represents the electrodes that are allowed to be turned on and their turn-on sequence. If the airflow at the air outlet is detected to be greater than the set threshold, the electrodes are sequentially shut off by the suppression adjustment matrix until the airflow at the air outlet is detected to be within the threshold range. If the airflow at the air outlet is detected to be less than the set threshold, the electrodes are activated sequentially through the enhanced adjustment matrix until the airflow at the air outlet is detected to be within the threshold range.

[0017] The beneficial effects of this invention are: this invention can flexibly control the opening or closing of electrodes, thereby adjusting the output power in real time according to the environment or user needs; by controlling the number of electrodes on, stepless speed regulation can be achieved, breaking through the limitations of traditional gears; at the same time, the multi-layer electrode matrix can achieve three-dimensional airflow guidance, forming directional airflow or diffused airflow, achieving the effect of precise airflow control.

[0018] By cyclically switching the electrode matrix activation sequence, the usage time of different electrodes is balanced, avoiding excessive wear of some electrodes due to prolonged use, thereby extending the overall service life of the electrodes and reducing the maintenance cost of the equipment.

[0022] The block diagrams shown in the accompanying drawings are merely functional entities and do not necessarily correspond to physically independent entities. That is, these functional entities can be implemented in software, in one or more hardware modules or integrated circuits, or in different network and / or processor devices and / or microcontroller devices.

[0023] The flowcharts shown in the accompanying drawings are merely illustrative and do not necessarily include all content and operations / steps, nor do they necessarily have to be performed in the described order. For example, some operations / steps can be broken down, while others can be combined or partially combined; therefore, the actual execution order may change depending on the specific circumstances.

[0024] Example 1: A silent air cooler that achieves dynamic switching of the electrode matrix, such as Figure 1 As shown, it includes: A high-voltage generator is used to produce high voltage. The electrodes generate an electric field when activated, ionizing air molecules to form an ion wind; Several electrode layers, each electrode layer including several electrodes in the same plane, and all electrodes are arranged in space to form an electrode output matrix; Electrode output controller is used to apply high voltage to the electrodes and control the electrodes to turn on or off. The number of electrodes turned on in different electrode output matrices controls the air cooler to be in different working modes. An airflow sensor is used to detect the airflow at the air vent.

[0025] This design allows for flexible control of electrode opening and closing, enabling real-time adjustment of output power based on environmental or user needs. By controlling the number of electrodes open, stepless speed regulation can be achieved, breaking through the limitations of traditional gears. Simultaneously, the multi-layer electrode matrix can achieve three-dimensional airflow guidance, forming directional or diffused airflow, achieving precise airflow control.

[0026] A control method for a silent air cooler that achieves dynamic switching of the electrode matrix, based on a silent air cooler that achieves dynamic switching of the electrode matrix, includes setting an accelerated airflow working mode, specifically: The system can be set to different speed-enhancing airflow modes, with the speed gradient increasing from low to high according to the speed level. In the low-speed acceleration airflow mode, fewer electrodes are activated in the electrode layer near the air outlet, while in the high-speed acceleration airflow mode, more electrodes are activated in the electrode layer near the air outlet. The number of electrodes activated in the electrode layer near the air outlet is always less than or equal to the number of electrodes activated in the electrode layer farther from the air outlet.

[0027] This design allows for different acceleration airflow modes to meet user needs in various scenarios. Adjusting the number of electrodes activated near and away from the air outlet based on the selected speed ensures a more even airflow distribution, preventing localized areas of excessive or insufficient airflow and improving both cooling and ventilation efficiency.

[0028] Below is an example of an application of accelerated airflow operating mode control: Taking a layout of 40 independent electrodes, evenly distributed across 4 layers from front to back, with 10 electrodes per layer as an example (similar to...). Figure 2 With four layers of electrodes, a working mode is provided that activates the electrodes along the air duct direction in a "sparser front, denser back" pattern, thereby enhancing the airflow through gradient and forming an accelerated airflow. The gear control algorithm is described as follows: Based on the electrode layout, establish an electrode output matrix with sparser front and denser back for different speed settings, taking speeds 1, 2, and 3 as an example, where speed 1 has the lowest airflow and speed 3 has the highest airflow.

[0029] An electrode output state is represented by a 4x10 matrix. The first row represents the output state of the electrode closest to the air outlet, where 0 indicates off output and 1 indicates on output. Rows 2, 3, and 4 represent the output states of the electrodes furthest from the air outlet. The matrix values ​​can be optimized based on the electrode layout and airflow design, combined with experiments.

[0030] Press S1 to activate the electrode in gear 1, S2 to activate the electrode in gear 2, and S3 to activate the electrode in gear 3, forming a gradient enhancement and acceleration airflow working mode with different air volume.

[0031] Example 2: A silent air cooler and control method for realizing dynamic switching of electrode matrix, the principle and implementation method of which are basically the same as those of Example 1, such as... Figure 2 As shown, the difference is: Set an electrode even distribution working mode. In the electrode even distribution working mode, set several different electrode output matrices, and then cyclically switch the electrode matrix activation sequence to make the usage time of different electrodes equal. The cyclic switching process is as follows: Step 1, set a certain electrode output matrix as the initial electrode output matrix, and the electrode outputs according to the state of the initial electrode output matrix. Step 2: Set the corresponding switching target value, and switch to different electrode output matrices sequentially according to the activation sequence; Step 3: Compare the difference between the current electrode output matrix and the switching target value, identify the electrodes that need to be adjusted and switch them accordingly. Each time, the number of electrodes adjusted is 1. Step 4: Update the electrode output matrix and jump back to step 2.

[0032] This design utilizes a cyclically switching electrode matrix activation sequence to ensure balanced usage time for different electrodes. This prevents excessive wear on some electrodes due to prolonged use, thereby extending the overall lifespan of the electrodes and reducing equipment maintenance costs. Adjusting only a small number of electrodes at a time allows for smoother airflow changes in the evaporative cooler, avoiding sudden and drastic fluctuations in airflow caused by adjusting too many electrodes at once, which could lead to an uncomfortable user experience.

[0033] Below is an application example of an electrode even distribution working mode: Taking a layout of 40 independent electrodes, evenly distributed across 4 layers from front to back, with 10 electrodes per layer as an example (similar to...). Figure 2 With four layers of electrodes, it provides an intelligent electrode distribution mode, maintaining uniform airflow, evenly distributing electrode usage frequency, and reducing the failure rate of premature aging of individual electrodes. Based on the electrode layout, establish the initial sequence of electrode output matrix for different speeds, taking speeds 1, 2, and 3 as an example, where speed 1 has the lowest airflow and speed 3 has the highest airflow.

[0034] An electrode output state is represented by a 4x10 matrix. The first row represents the output state of the electrode closest to the air outlet, where 0 indicates off output and 1 indicates on output. The second, third, and fourth rows represent the output states of the electrodes furthest from the air outlet. The initial setting for the first gear is to turn on 20 electrodes. An initial electrode output matrix sequence is as follows. The matrix values ​​can be optimized by combining the electrode layout and airflow design with experiments.

[0035] Two initial settings activate 30 electrodes. One initial electrode output matrix sequence setting is as follows: The initial setting for the 3rd gear is 40 electrodes. In order to ensure that the usage time of each electrode is relatively balanced during the operation of the fan at a certain level, it is necessary to switch electrodes according to the electrode output matrix sequence. The switching of electrodes needs to be smooth to avoid significant fluctuations in air volume during the switching process. The following electrode smoothing switching method can be adopted.

[0036] Taking the first-level electrode switching mode as an example, the electrode activation sequence is switched cyclically according to the electrode output matrix sequence D1_S1, D1_S2, D1_S3, D1_S4: (1) Initial state electrode output matrix OUT_MATRIX = D1_S1, electrode control outputs according to OUT_MATRIX state; (2) Perform target state cyclic switching according to the target state cyclic switching order D1_S1, D1_S2, D1_S3, D1_S4, and set the corresponding switching target value; (3) Compare the difference between OUT_MATRIX and the target electrode output matrix. If they are different, find a small number of different electrodes to switch each time (e.g., switch one at a time) and update the OUT_MATRIX state matrix and the corresponding output. (4) Repeat step (3) to switch electrodes until the target state is reached; (5) Return to step (2); Example 3: A silent air cooler and its control method for dynamically switching electrode matrices. Its principle and implementation are basically the same as in Example 2, except that: In step 3, after the electrode switching, the air volume sensor detects the air volume at the air outlet and compares the detected air volume at the air outlet with a set threshold. If the detected air volume at the air outlet is within the set threshold, the process jumps to step 4. If the detected air volume at the air outlet is outside the set threshold, the electrode is adjusted and the air volume at the air outlet is detected again until the air volume no longer exceeds the set threshold.

[0037] The method for adjusting the electrodes is as follows: Set up a suppression control matrix and an enhancement control matrix. The suppression control matrix represents the electrodes that are allowed to be turned off and their turn-off sequence, while the enhancement control matrix represents the electrodes that are allowed to be turned on and their turn-on sequence. If the airflow at the air outlet is detected to be greater than the set threshold, the electrodes are sequentially shut off by the suppression adjustment matrix until the airflow at the air outlet is detected to be within the threshold range. If the airflow at the air outlet is detected to be less than the set threshold, the electrodes are activated sequentially through the enhanced adjustment matrix until the airflow at the air outlet is detected to be within the threshold range.

[0038] Taking level 1 as an example, one form of the suppression regulation matrix sequence is as follows: This indicates the 8 electrodes that can be turned off and their shutdown order when the corresponding D1_S1 output is pressed, in order to reduce airflow. This indicates the 8 electrodes that can be turned off and their shutdown order when the corresponding D1_S2 output is applied, in order to reduce airflow. This indicates the 8 electrodes that can be shut down and their shutdown order when the corresponding D1_S3 output is applied, in order to reduce airflow. This indicates the 8 electrodes that can be turned off and their turning order when the corresponding D1_S4 output is applied. The enhanced airflow adjustment matrix indicates the electrodes that can be controlled to be turned on and their preferred turning order at the corresponding speed setting. The turning order can be optimized based on the electrode layout and airflow design, combined with experimental results. Taking level 1 as an example, one form of enhanced adjustment matrix sequence is as follows: This indicates the 10 electrodes that can be opened and their opening order when the corresponding D1_S1 output is pressed, used to increase airflow. This indicates the 10 electrodes that can be opened and their opening order when the corresponding D1_S2 output is pressed, used to increase airflow. This indicates the 10 electrodes that can be opened and their opening order when the corresponding D1_S3 output is pressed, used to increase airflow. This indicates the 10 electrodes that can be opened and their opening order when the corresponding D1_S4 output is pressed, used to increase airflow. Taking level 1 as an example, the airflow control process through wind speed feedback and adjustment matrix is ​​as follows: (1) Initial state electrode output matrix OUT_MATRIX = D1_S1, electrode control outputs according to OUT_MATRIX state; (2) Perform target state cyclic switching according to the target state cyclic switching order D1_S1, D1_S2, D1_S3, D1_S4, and set the corresponding switching target value; (3) Compare the difference between OUT_MATRIX and the target electrode output matrix. If they are different, find a small number of different electrodes to switch (e.g., one) each time, and update the OUT_MATRIX state matrix and the corresponding output. (4) Repeat step (3) to switch electrodes and compare the detected average air volume with the set threshold. If the detected air volume is within the set threshold and the electrode output is fully switched to the target state, return to step (2). If the detected air volume is higher than the threshold, execute step (5). If the detected air volume is lower than the threshold, execute step (7). (5) Based on the data in the corresponding suppression matrix, adjust the output matrix OUT_MATRIX and the corresponding electrode output in sequence until the air volume no longer exceeds the corresponding threshold, or all electrodes that are allowed to be closed are closed. (6) Return to step (2); (7) Based on the data in the corresponding enhancement matrix, adjust the output matrix OUT_MATRIX and the corresponding electrode output in sequence until the air volume no longer exceeds the corresponding threshold, or all electrodes that are allowed to be closed are opened. (8) Return to step (2).
