Description

Technical Field

[0001] This application relates to the field of air conditioning, and more particularly to an air conditioner and its dust control method, storage medium and product. Background Art

[0002] During air conditioner operation, airflow enters the unit through the air inlet, exchanges heat through the heat exchanger, and is then blown out through the air outlet, thus achieving heat exchange. The air inlet is typically located at the top of the unit, which makes the heat exchanger prone to dust accumulation. Furthermore, in high-temperature and high-humidity environments, bacteria can easily grow on the heat exchanger, causing the airflow from the outlet to have a musty smell, affecting the user experience and health.

[0003] In related technologies, to reduce dust entering the air conditioner through the air inlet, an air inlet baffle assembly is often installed at the air inlet. When the air conditioner is idle, the air inlet baffle assembly is closed to prevent dust from entering the air conditioner through the air inlet; when the air conditioner is working, the air inlet baffle assembly is open to expose the air inlet. However, while the closed air inlet prevents dust from entering the air conditioner when the air conditioner is idle, dust accumulates on the air inlet baffle assembly. When the air conditioner is turned on, the airflow from the air inlet blows the dust and other foreign objects attached to the surface of the air inlet baffle assembly into the air conditioner. In other words, when the air inlet baffle assembly is open, the dust falls back into the air conditioner, failing to fundamentally prevent dust from entering the air conditioner. Summary of the Invention

[0004] In view of this, embodiments of this application provide an air conditioner and its dust prevention control method, storage medium and product, which aim to improve the dust prevention effect of the air conditioner.

[0005] The technical solution of this application embodiment is implemented as follows:

The third detection element is close to the third magnetic force generating device, and the fourth detection element is close to the second magnetic force generating device. The distance from the third detection element to the longitudinal centerline of the air inlet is equal to the distance from the fourth detection element to the longitudinal centerline of the air inlet.

[0040] In response to a shutdown command to turn off the air conditioner, the air conditioner is controlled to stop operating and the input power of each of the magnetic force generating devices is gradually reduced, causing the suspension plate assembly to descend until it covers the air inlet.

The magnetic force generating devices are electrically connected to the control module, and the detection elements are also electrically connected to the control module. The suspension plate assembly includes a suspension plate and multiple magnetic elements disposed on the suspension plate. The magnetic elements on the suspension plate are disposed opposite to the magnetic force generating devices. After the magnetic force generating devices are powered on, electromagnetic repulsion is generated between them and the magnetic elements. The detection elements generate an electrical signal based on the magnetic field generated by the magnetic elements and the magnetic force generating devices. The electrical signal is used to determine the positional relationship between the suspension plate assembly and the air inlet. The control module is configured to control the input power of each magnetic force generating device based on the electrical signal, so that the suspension plate assembly is suspended above the air inlet.

[0052] The present application will now be described in further detail with reference to the accompanying drawings and embodiments.

[0053] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0054] This application provides an air conditioner for regulating the temperature and humidity of the environment. The air conditioner can be a cooling-only unit or a cooling and heating unit, and can be a wall-mounted, floor-standing, or window unit, etc. This application does not specifically limit the type. It should be noted that the air conditioner can be an integrated air conditioning structure or a separate air conditioning structure. A separate air conditioning structure includes an indoor unit and an outdoor unit, while an integrated air conditioning structure integrates all system components into a single casing.

[0055] In this embodiment of the application, the air conditioner includes: an air conditioner body and a suspension plate assembly. The suspension plate assembly is used to cooperate with the air inlet on the air conditioner body to close or open the air inlet. Figure 1As shown, the air conditioner body includes a housing 100 and a control module (not shown). The housing 100 has an air inlet 101. The air conditioner body also includes multiple magnetic force generating devices 200 and detection elements 300 disposed at the air inlet. The magnetic force generating devices 200 and the detection elements 300 are electrically connected to the control module. The suspension plate assembly includes a suspension plate 400 and multiple magnetic elements 500 disposed on the suspension plate 400. The magnetic elements 500 on the suspension plate 400 are disposed opposite to the magnetic force generating devices 200. After the magnetic force generating devices 200 are powered on, an electromagnetic repulsion force is generated between them and the magnetic elements 500. The detection elements 300 generate an electrical signal based on the magnetic field generated by the magnetic elements 500 and the magnetic force generating devices 200. The electrical signal is used to determine the positional relationship between the suspension plate assembly and the air inlet 101. The control module is configured to control the input power of each magnetic force generating device 200 based on the electrical signal, so that the suspension plate assembly is suspended above the air inlet 101.

[0056] It should be noted that if the control module controls the magnetic force generating device 200 to start, the magnetic force generating device 200 can generate an electromagnetic repulsion between itself and the magnetic element 500 after being powered on, so that the suspension plate assembly is suspended at a set height above the air inlet 101, thereby opening the air inlet 101; if the control module controls the magnetic force generating device 200 to be powered off, the electromagnetic repulsion between the magnetic force generating device 200 and the magnetic element 500 will gradually disappear, so that the suspension plate assembly descends and covers the air inlet 101, thereby closing the air inlet 101.

[0057] It is understood that, in this embodiment of the application, by introducing a suspension plate assembly that cooperates with the air inlet 101 of the air conditioner, and based on the control of the power-on state of the magnetic force generating device 200, the suspension plate assembly can be switched between being suspended above the air inlet 101 when the air conditioner is running and covering the air inlet 101 when the air conditioner is stopped. In this way, it can prevent dust and other foreign objects from entering the air conditioner when it is idle, and also prevent the airflow from the air inlet 101 after the air conditioner is started from bringing the blocked dust and other foreign objects into the air conditioner, thereby effectively improving the dustproof effect of the air conditioner.

[0058] Here, the magnetic force generating device 200 can be an electromagnet, that is, a device that generates electromagnetism based on energization. For example, a conductive coil matching its power is wound around the outside of an iron core. The conductive coil will have magnetism like a magnet after being energized. It should be noted that an electromagnet has the characteristic of generating magnetism when energized and losing magnetism when de-energized. Based on the above characteristics of the electromagnet, it can cooperate with the magnetic element 500 set on the suspension plate 400. The magnetic force generating device 200 and the magnetic element 500 are arranged opposite to each other, so that the suspension plate assembly is suspended at a set height above the air inlet 101.

[0059] It should be noted that when the air conditioner in this embodiment is running, the suspension plate assembly is suspended directly above the air inlet 101. If the suspension plate assembly is subjected to an uncontrollable external force, causing the relative positional relationship between the suspension plate assembly and the air inlet 101 in the horizontal direction to change, the relative positional relationship between the magnetic element 500 and the magnetic force generating device 200 will shift, and the direction of the electromagnetic repulsion between the magnetic element 500 and the magnetic force generating device 200 will change. Furthermore, the vertical component of the electromagnetic repulsion between the magnetic element 500 and the magnetic force generating device 200 will decrease and a horizontal component will be generated, causing the suspension plate assembly to be unable to float stably.

[0060] It should be noted that when the direction and / or magnitude of the electromagnetic repulsion between the magnetic element 500 and the magnetic force generating device 200 changes, the magnitude of the horizontal component of the electromagnetic repulsion also changes.

[0061] It is understood that the air conditioner in this embodiment of the application is equipped with a detection element 300 to detect the positional relationship between the suspension plate assembly and the air inlet 101. The control module controls the input power of each magnetic force generating device 200 based on the electrical signal generated by the detection element 300 that represents the detection result. That is, it controls the magnitude of the electromagnetic repulsion between each magnetic force generating device 200 and the magnetic element 500 to adjust the horizontal attitude of the suspension plate assembly when it is suspended, so as to ensure that the suspension plate assembly is stably suspended to the set height.

[0062] Here, the input power supply of the magnetic force generating device 200 can be either the input current or the input voltage of the magnetic force generating device 200. That is, the magnitude of the electromagnetic repulsion between the magnetic force generating device 200 and the magnetic element 500 can be adjusted by controlling the input current or the input voltage of the magnetic force generating device 200.

[0063] The detection element 300 in this application embodiment can be understood as a detection element for detecting magnetic induction intensity. For example, the detection element 300 can be a Hall element based on the Hall effect.

[0064] Furthermore, the electrical signal generated by the detection element 300 is a voltage signal.

[0065] It should be noted that under the influence of a magnetic field, the detection element 300 will generate a voltage signal based on electromagnetic induction. The closer the detection element 300 is to the magnetic element 500, the larger the voltage signal generated by the detection element 300. The control module can indirectly determine the relative position of the suspension plate assembly based on the received voltage signal.

[0066] For example, the air inlet 101 is rectangular, and the suspension plate 400 is rectangular, such as... Figure 2As shown, the plurality of magnetic force generating devices 200 include: a first magnetic force generating device 201, a second magnetic force generating device 202, a third magnetic force generating device 203, and a fourth magnetic force generating device 204 respectively disposed at the four corners of the air inlet 101. The plurality of magnetic elements 500 include: a first magnetic element 501, a second magnetic element 502, a third magnetic element 503, and a fourth magnetic element 504. Specifically, the first magnetic element 501 is disposed opposite to the first magnetic force generating device 201, the second magnetic element 502 is disposed opposite to the second magnetic force generating device 202, the third magnetic element 503 is disposed opposite to the third magnetic force generating device 203, and the fourth magnetic element 504 is disposed opposite to the fourth magnetic force generating device 204.

[0067] For example, a first magnetic force generating device 201 is disposed at the upper left corner of the air inlet 101; a second magnetic force generating device 202 is disposed at the upper right corner of the air inlet 101; a third magnetic force generating device 203 is disposed at the lower left corner of the air inlet 101; and a fourth magnetic force generating device 204 is disposed at the lower right corner of the air inlet 101. The first magnetic force generating device 201 and the second magnetic force generating device 202 are symmetrically arranged along the longitudinal center line of the air inlet 101, the third magnetic force generating device 203 and the fourth magnetic force generating device 204 are symmetrically arranged along the longitudinal center line of the air inlet 101, the first magnetic force generating device 201 and the third magnetic force generating device 203 are symmetrically arranged along the transverse center line of the air inlet 101, and the second magnetic force generating device 202 and the fourth magnetic force generating device 204 are symmetrically arranged along the transverse center line of the air inlet 101. The transverse center line of the air inlet 101 is as follows: Figure 2 As shown by the dashed line A in the diagram, the longitudinal centerline of the air inlet 101 is as follows: Figure 2 As shown by the dashed line B in the diagram.

[0068] It is understood that in this embodiment of the application, multiple magnetic force generating devices 200 are symmetrically arranged at the four corners of the air inlet 101 according to the horizontal center line and the vertical center line of the air inlet 101. The distance from each magnetic force generating device 200 to the horizontal center line of the air inlet 101 is equal, and the distance from each magnetic force generating device 200 to the vertical center line of the air inlet 101 is equal. When the air conditioner is running, electromagnetic repulsion is generated between the first magnetic element 501 and the first magnetic force generating device 201, between the second magnetic element 502 and the second magnetic force generating device 202, between the third magnetic element 503 and the third magnetic force generating device 203, and between the fourth magnetic element 504 and the fourth magnetic force generating device 204. The control module controls each electromagnetic repulsion to approach the set electromagnetic repulsion, so that the suspension plate assembly is subjected to uniform force and can stably levitate to the set height.

[0069] For example, the detection element 300 includes a longitudinal detection element and a transverse detection element. The longitudinal detection element is disposed between the first magnetic force generating device 201 and the third magnetic force generating device 203, and / or between the second magnetic force generating device 202 and the fourth magnetic force generating device 204, for detecting the longitudinal positional relationship between the suspension plate assembly and the air inlet 101. The transverse detection element is disposed between the first magnetic force generating device 201 and the second magnetic force generating device 202, and / or between the third magnetic force generating device 203 and the fourth magnetic force generating device 204, for detecting the transverse positional relationship between the suspension plate assembly and the air inlet 101. The transverse positional relationship and the longitudinal positional relationship are the relative positional relationship between the suspension plate assembly and the air inlet 101 in the horizontal direction.

[0070] For example, the longitudinal detection element includes a first detection element 301 and a second detection element 302. The first detection element 301 is close to the third magnetic force generating device 203, and the second detection element 302 is close to the second magnetic force generating device 202. The distance from the first detection element 301 to the lateral center line of the air inlet 101 is equal to the distance from the second detection element 302 to the lateral center line of the air inlet 101. The lateral detection element includes a third detection element 303 and a fourth detection element 304. The third detection element 303 is close to the third magnetic force generating device 203, and the fourth detection element 304 is close to the second magnetic force generating device 202. The distance from the third detection element 303 to the longitudinal center line of the air inlet 101 is equal to the distance from the fourth detection element 304 to the longitudinal center line of the air inlet 101. The first detection element 301 is used to generate a first electrical signal based on the magnetic field generated by the third magnetic element 503 and the third magnetic force generating device 203; the second detection element 302 is used to generate a second electrical signal based on the magnetic field generated by the second magnetic element 502 and the second magnetic force generating device 202; the third detection element 303 is used to generate a third electrical signal based on the magnetic field generated by the third magnetic element 503 and the third magnetic force generating device 203; and the fourth detection element 304 is used to generate a fourth electrical signal based on the magnetic field generated by the second magnetic element 502 and the third magnetic force generating device 202.

[0071] It should be noted that the first detection element 301 is disposed between the first magnetic force generating device 201 and the third magnetic force generating device 203, the second detection element 302 is disposed between the second magnetic force generating device 202 and the fourth magnetic force generating device 204, the third detection element 303 is disposed between the third magnetic force generating device 203 and the fourth magnetic force generating device 204, and the fourth detection element 304 is disposed between the first magnetic force generating device 201 and the second magnetic force generating device 202.

[0072] It is understandable that, since the distance from the first detection element 301 to the lateral center line of the air inlet 101 is equal to the distance from the second detection element 302 to the lateral center line of the air inlet 101, when the suspension plate assembly is located directly above the air inlet 101 in the vertical direction, the distance from the first detection element 301 to the third magnetic element 503 is equal to the distance from the second detection element 302 to the second magnetic element 502. At this time, the first electrical signal is equal to the second electrical signal.

[0073] It is understandable that, since the distance from the third detection element 303 to the longitudinal center line of the air inlet 101 is equal to the distance from the fourth detection element 304 to the longitudinal center line of the air inlet 101, when the suspension plate assembly is located directly above the air inlet 101 in the vertical direction, the distance from the third detection element 303 to the third magnetic element 503 is equal to the distance from the fourth detection element 304 to the second magnetic element 502. At this time, the third electrical signal is equal to the fourth electrical signal.

[0074] It is understandable that if the suspension plate assembly shifts horizontally relative to the air inlet 101, the distance between the first detection element 301 and the third magnetic element 503 will no longer be equal to the distance between the second detection element 302 and the second magnetic element 502, and / or the distance between the third detection element 303 and the third magnetic element 503 will no longer be equal to the distance between the fourth detection element 304 and the second magnetic element 502. Accordingly, based on the variation law of the electrical signal generated by the detection element 300, it can be determined that the suspension plate assembly shifts horizontally relative to the air inlet 101.

[0075] It is understood that the horizontal detection element is set at the diagonal of the air inlet 101, and the vertical detection element is set at the diagonal of the air inlet 101. In this embodiment of the application, four detection elements are set to detect the relative position of the suspension plate assembly in the horizontal direction when it is suspended.

[0076] In one application example of this application, the first detection element 301 is close to the fourth magnetic force generating device 204, and the second detection element 302 is close to the first magnetic force generating device 201. The longitudinal positional relationship between the suspension plate assembly and the air inlet 101 can also be detected.

[0077] In one application example of this application, the third detection element 303 is close to the first magnetic force generating device 201, and the fourth detection element 304 is close to the fourth magnetic force generating device, which can also detect the lateral positional relationship between the suspension plate assembly and the air inlet 101.

[0078] For example, such as Figure 3As shown, the control module includes a master controller 600 and slave controllers, the slave controllers including a first slave controller 701, a second slave controller 702, a third slave controller 703 and a fourth slave controller 704. The main controller 600 is electrically connected to the detection element 300 and is used to send control commands to adjust the input power of the magnetic force generator 200 based on electrical signals. The first slave controller 701 is electrically connected to the main controller 600 and the first magnetic force generator 201 respectively and is used to control the input power of the first magnetic force generator 201 based on the received control commands. The second slave controller 702 is electrically connected to the main controller 600 and the second magnetic force generator 202 respectively and is used to control the input power of the second magnetic force generator 202 based on the received control commands. The third slave controller 703 is electrically connected to the main controller 600 and the third magnetic force generator 203 respectively and is used to control the input power of the third magnetic force generator 203 based on the received control commands. The fourth slave controller 704 is electrically connected to the main controller 600 and the fourth magnetic force generator 204 respectively and is used to control the input power of the fourth magnetic force generator 204 based on the received control commands.

[0079] Here, the main controller 600 is electrically connected to the first detection element 301, the second detection element 302, the third detection element 303 and the fourth detection element 304 respectively.

[0080] It should be noted that the main controller 600 determines the horizontal offset of the suspension plate assembly relative to the air inlet 101 based on the electrical signal, and generates control commands based on the determined horizontal offset. Specifically, the main controller 600 sends a first control command to the first slave controller 701, a second control command to the second slave controller 702, a third control command to the third slave controller 703, and a fourth control command to the first slave controller 704. The slave controllers control the input power of the corresponding magnetic force generating device 200 based on the received control commands.

[0081] Furthermore, the control command instructs the magnetic force generating device 200 to set a target value for the input current or a target value for the input voltage.

[0082] In one application example of this application, the master controller 600, the first slave controller 701, the second slave controller 702, the third slave controller 703, and the fourth slave controller 704 are respectively mounted on different control boards.

[0083] It should be noted that after confirming that the air conditioner has started, the control module is also used to control the input power of the magnetic force generator 200, so that the suspension plate assembly is suspended above the air inlet 101 at a set height.

[0084] This application also provides a dust control method based on the aforementioned air conditioner, such as... Figure 4 As shown, the method includes:

[0085] Step 401: In response to the start command of the air conditioner, control the air conditioner to start running and control the magnetic force generating device to be powered on.

[0086] Step 402: Acquire the electrical signal generated by the detection element.

[0087] Step 403: Based on the electrical signal, control the input power supply of each magnetic force generating device.

[0088] The input power supply is the input voltage or input current of the magnetic force generator 200.

[0089] Understandably, when the air conditioner is turned on, the magnetic force generating device 200 is powered on, and an electromagnetic repulsion force is generated between the magnetic force generating device 200 and the magnetic element 500. Under the action of the electromagnetic repulsion force, the suspension plate assembly is suspended above the air inlet 101.

[0090] It should be noted that when the suspension plate assembly is in a suspended state, if the suspension plate assembly shifts horizontally under the action of an external force, the magnetic element 500 is no longer located directly above the magnetic force generating device 200. The direction of the electromagnetic repulsion between the magnetic element 500 and the magnetic force generating device 200 changes. In addition to providing the vertical component force that makes the suspension plate assembly levitate, the electromagnetic repulsion force will also generate a horizontal component force. If the direction and / or magnitude of the electromagnetic repulsion force is not adjusted, the horizontal component force of the electromagnetic repulsion force will affect the stable levitation of the suspension plate assembly.

[0091] Understandably, when the suspension plate assembly is in a suspended state, the detection element 300 detects the horizontal position of the suspension plate assembly relative to the air inlet 101. If it is determined that the suspension plate assembly has shifted horizontally relative to the air inlet 101, the input power of the magnetic force generating device 200 is adjusted to adjust the direction and / or magnitude of the electromagnetic repulsion force to ensure that the suspension plate assembly is stably suspended directly above the air inlet 101.

[0092] For example, if the detection element 300 includes a longitudinal detection element and a transverse detection element, controlling the input power supply of each magnetic force generating device based on an electrical signal includes: obtaining a first parameter characterizing the longitudinal offset direction of the suspension plate assembly and a second parameter characterizing the longitudinal offset amount of the suspension plate assembly based on the electrical signal generated by the longitudinal detection element; and obtaining a third parameter characterizing the transverse offset direction of the suspension plate assembly and a fourth parameter characterizing the transverse offset amount of the suspension plate assembly based on the electrical signal generated by the transverse detection element; and controlling the input power supply of each magnetic force generating device based on the first parameter, the second parameter, the third parameter, and the fourth parameter.

[0093] For example, if the longitudinal detection element includes a first detection element 301 and a second detection element 302, a first parameter characterizing the longitudinal offset direction of the suspension plate assembly and a second parameter characterizing the longitudinal offset amount of the suspension plate assembly are obtained based on the electrical signal generated by the longitudinal detection element; this includes: obtaining the first parameter based on the magnitude relationship between the voltage value of the first electrical signal generated by the first detection element and the voltage value of the second electrical signal generated by the second detection element; and obtaining the second parameter based on the voltage difference between the first electrical signal and the second electrical signal.

[0094] For example, if the lateral detection element includes a third detection element 303 and a fourth detection element 304, a third parameter characterizing the lateral offset direction of the suspension plate assembly and a fourth parameter characterizing the lateral offset amount of the suspension plate assembly are obtained based on the electrical signal generated by the lateral detection element. This includes: obtaining the third parameter based on the magnitude relationship between the voltage value of the third electrical signal generated by the third detection element and the voltage value of the fourth electrical signal generated by the fourth detection element; and obtaining the fourth parameter based on the voltage difference between the third electrical signal and the fourth electrical signal.

[0095] It should be noted that the voltage of the electrical signal generated by the detection element 300 is directly proportional to the magnetic induction intensity of the vertical magnetic field through which the detection element 300 passes. The detection element 300 and the magnetic force generating device 200 are installed on the air conditioner body. The closer the detection element 300 is to the magnetic element 500, the greater the voltage value of the electrical signal generated by the detection element 300.

[0096] Furthermore, when the suspension plate assembly is directly above the air inlet 101 vertically, the voltage value of the first electrical signal is equal to the voltage value of the second electrical signal. If the voltage value of the first electrical signal is no longer equal to the voltage value of the second electrical signal, based on the relationship between the voltage values ​​of the first and second electrical signals, the relationship between the distance from the first detection element 301 to the third magnetic element 503 and the distance from the second detection element 302 to the second magnetic element 502 can be determined, i.e., the longitudinal offset direction of the suspension plate assembly can be determined. Similarly, based on the relationship between the voltage values ​​of the third and fourth electrical signals, the lateral offset direction of the suspension plate assembly can be determined.

[0097] For example, a first parameter is obtained based on the relationship between the voltage values ​​of the first electrical signal generated by the first detection element and the voltage values ​​of the second electrical signal generated by the second detection element, including: if it is determined that the voltage value of the first electrical signal is greater than the voltage value of the second electrical signal, the first parameter indicates that the suspension plate assembly has shifted upward; if it is determined that the voltage value of the first electrical signal is less than the voltage value of the second electrical signal, the first parameter indicates that the suspension plate assembly has shifted downward; if it is determined that the voltage value of the first electrical signal is equal to the voltage value of the second electrical signal, the first parameter indicates that the suspension plate assembly has not shifted longitudinally.

[0098] For example, a third parameter is obtained based on the relationship between the voltage value of the third electrical signal generated by the third detection element and the voltage value of the fourth electrical signal generated by the fourth detection element, including: if it is determined that the voltage value of the third electrical signal is greater than the voltage value of the fourth electrical signal, the third parameter indicates that the suspension plate assembly shifts to the right; if it is determined that the voltage value of the third electrical signal is less than the voltage value of the fourth electrical signal, the third parameter indicates that the suspension plate assembly shifts to the left; if it is determined that the voltage value of the third electrical signal is equal to the voltage value of the fourth electrical signal, the third parameter indicates that the suspension plate assembly has not shifted laterally.

[0099] Understandably, the first detection element 301 is positioned above the third magnetic force generating device 203 (i.e., the first detection element 301 is located between the third magnetic force generating device 203 and the transverse center line of the air inlet 101), and the second detection element 302 is positioned below the second magnetic force generating device 202 (i.e., the second detection element 302 is located between the second magnetic force generating device 202 and the transverse center line of the air inlet 101). If the suspension plate assembly shifts upward, the voltage value of the first electrical signal is greater than the voltage value of the second electrical signal; similarly, if the suspension plate assembly shifts downward, the voltage value of the first electrical signal is less than the voltage value of the second electrical signal.

[0100] Understandably, the third detection element 303 is located on the right side of the third magnetic force generating device 203, and the fourth magnetic force generating device 304 is located on the left side of the second magnetic force generating device 202. If the suspension plate assembly shifts to the right, the voltage value of the third electrical signal is greater than the voltage value of the fourth electrical signal; similarly, if the suspension plate assembly shifts to the left, the voltage value of the third electrical signal is less than the voltage value of the fourth electrical signal.

[0101] It should be noted that the second parameter is the voltage difference between the first and second electrical signals. The larger the second parameter, the greater the longitudinal offset of the suspension plate assembly. The fourth parameter is the voltage difference between the third and fourth electrical signals. The larger the fourth parameter, the greater the lateral offset of the suspension plate assembly.

[0102] It should be noted that after the main controller 600 acquires the first, second, third, and fourth electrical signals, it calculates the first, second, third, and fourth parameters. The main controller 600 configures a proportional-integral-differential (PID) control algorithm model. The main controller 600 inputs the first, second, third, and fourth parameters into the PID algorithm model to obtain control commands indicating the target values ​​of the input current or input voltage of each magnetic force generating device 200. Based on the control commands, the controller adjusts the input power of the corresponding magnetic force generating device 200, that is, adjusts the magnitude of the electromagnetic repulsion between each magnetic force generating device 200 and the corresponding magnetic element 500. The horizontal attitude of the suspension plate assembly changes, thereby reducing the horizontal component of the electromagnetic repulsion, so that the suspension plate assembly is stably suspended above the air inlet 101.

[0103] In some application examples, the main controller 600, configured with a proportional-integral (PI) control algorithm model or a proportional-differential (PD) control algorithm model, can also calculate control commands that instruct the target values ​​of the input current or input voltage of each magnetic force generating device 200.

[0104] For example, the method further includes: if it is determined that the suspension plate has not shifted horizontally relative to the air inlet, controlling the input power of each magnetic force generating device to gradually increase to a set threshold, so that the suspension plate assembly is suspended above the air inlet at a set height.

[0105] It should be noted that the magnitude of the electromagnetic repulsion between the magnetic force generating device 200 and the magnetic element 500 is related to the number of coil turns of the magnetic force generating device 200, the input power supply of the magnetic force generating device 200, and the distance between the magnetic force generating device 200 and the magnetic element 500. Increasing the input power supply of the magnetic force generating device 200 increases the electromagnetic repulsion between the magnetic force generating device 200 and the magnetic element 500. If the electromagnetic repulsion is greater than the weight of the suspension plate assembly, the suspension plate assembly will rise. During the rising process of the suspension plate assembly, the distance between the magnetic force generating device 200 and the magnetic element 500 increases, and the electromagnetic repulsion between them decreases. After the input power supply of the magnetic force generating device 200 increases to a set threshold and remains constant, the electromagnetic repulsion gradually decreases during the rising process of the suspension plate assembly. When the electromagnetic repulsion equals the weight of the suspension plate assembly, the suspension plate assembly stops rising. At this point, the distance between the suspension plate assembly and the air inlet 101 is the set height.

[0106] It should be noted that the input power of each magnetic force generating device 200 needs to be gradually and slowly increased to the set threshold. If the input power of each magnetic force generating device 200 is increased rapidly to the set threshold instantaneously, the vertical acceleration of the suspension plate assembly will be too large, which may cause the suspension control of the suspension plate assembly to overshoot, which is not conducive to the stable suspension of the suspension plate assembly.

[0107] In one application example of this application, the main controller 600 is configured with a longitudinal electrical signal setting value and a lateral electrical signal setting value. The longitudinal electrical signal setting value is the voltage value of the electrical signal generated by the longitudinal detection element when the suspension plate assembly is suspended at a set height above the air inlet 101. The lateral electrical signal setting value is the voltage value of the electrical signal generated by the lateral detection element when the suspension plate assembly is suspended at a set height above the air inlet 101. Based on comparing the voltage values ​​of the first electrical signal and the longitudinal electrical signal setting value, comparing the voltage values ​​of the second electrical signal and the longitudinal electrical signal setting value, comparing the voltage values ​​of the third electrical signal and the lateral electrical signal setting value, and comparing the voltage values ​​of the fourth electrical signal and the lateral electrical signal setting value, the main controller 600 can determine the set height at which the suspension plate assembly is suspended above the air inlet 101.

[0108] It should be noted that, in response to the start-up command of the air conditioner, the control module controls the air conditioner to start running and controls the magnetic force generating device 200 to be powered on. Then, it controls the input power of each magnetic force generating device 200 to gradually increase to a set threshold, which can make the suspension plate assembly suspend above the air inlet 101 at a set height.

[0109] It should be noted that if the suspension plate assembly shifts in the horizontal direction, the control module adjusts the horizontal attitude of the suspension plate assembly by reducing the input power of one or more magnetic force generating devices 200. After the horizontal attitude of the suspension plate assembly is adjusted, the control module increases the input power of each magnetic force generating device 200 again to the set threshold, so that the suspension plate assembly can be suspended again at the set height above the air inlet 101.

[0110] For example, the method further includes: in response to a shutdown command to turn off the air conditioner, controlling the air conditioner to stop operating and controlling the input power of each magnetic force generating device to gradually decrease, causing the suspension plate assembly to descend until it covers the air inlet.

[0111] Understandably, in response to the shutdown command of the air conditioner, the control module not only controls the air conditioner to stop running, but also needs to control the input power of the magnetic force generating device 200 to gradually decrease until the magnetic force generating device 200 is de-energized, thereby causing the suspension plate assembly to descend and cover the air inlet 101, thus closing the air inlet 101 and preventing external dust from entering the air conditioner when it is idle.

[0112] In one application example of this application, a dust control method for an air conditioner is provided, such as... Figure 5 As shown, the method includes:

[0113] Step 501: In response to the start-up command of the air conditioner, control the air conditioner to start.

[0114] Here, the air conditioner's control module receives the power-on command sent by the user, and controls the air conditioner to start while simultaneously opening the air inlet 101.

[0115] Step 502: Power on the magnetic force generating device to levitate the suspension plate assembly.

[0116] Here, the height of the suspension plate assembly from the air inlet 101 when it is stable can be determined based on the input power supply of the magnetic force generating device 200, which is one of the following: the input current or the input voltage of the magnetic force generating device 200.

[0117] Here, the main controller 600 responds to the power-on command and instructs the controller to power on the magnetic force generator 200 based on the serial port command.

[0118] Step 503: Obtain the first voltage value U_Y1, the second voltage value U_Y2, the third voltage value U_X1, and the fourth voltage value U_X2.

[0119] Here, U_Y1 is the voltage value of the first electrical signal generated by the first detection element 301, U_Y2 is the voltage value of the second electrical signal generated by the second detection element 302, U_X1 is the voltage value of the third electrical signal generated by the third detection element 303, and U_X2 is the voltage value of the fourth electrical signal generated by the fourth detection element 304.

[0120] Step 504: Determine if U_Y1 > U_Y2. If yes, proceed to step 506; otherwise, proceed to step 507.

[0121] Step 505: Determine if U_X1 > U_X2. If yes, proceed to step 508; otherwise, proceed to step 509.

[0122] Step 506 yields the first parameter D_Y = D_A and the second parameter U_Y_Offset = U_Y1 - U_Y2.

[0123] Here, the first parameter D_Y represents the longitudinal offset direction of the suspension plate assembly, and D_A indicates that the suspension plate assembly is offset upward; the second parameter U_Y_Offset represents the longitudinal offset of the suspension plate assembly and is used to determine the target value of the input power supply of the magnetic force generating device 200.

[0124] Step 507 yields the first parameter D_Y = D_B and the second parameter U_Y_Offset = U_Y2 - U_Y1.

[0125] Here, D_B indicates that the suspension plate assembly has shifted downwards.

[0126] Step 508 yields the third parameter D_X = D_R and the fourth parameter U_X_Offset = U_X1 - U_X2.

[0127] Here, the third parameter D_X represents the lateral offset direction of the suspension plate assembly, and D_R indicates that the suspension plate assembly offsets to the right; the fourth parameter U_X_Offset represents the lateral offset amount of the suspension plate assembly, which is used to determine the target value of the input power supply of the magnetic force generating device 200.

[0128] Step 509 yields the third parameter D_X = D_L and the fourth parameter U_X_Offset = U_X2 - U_X1.

[0129] Here, D_L indicates that the suspension plate assembly has shifted to the left.

[0130] Step 510: Based on the first parameter D_Y, the second parameter U_Y_Offset, the third parameter D_X, and the fourth parameter U_X_Offset, the first control instruction I1, the second control instruction I2, the third control instruction I3, and the fourth control instruction I4 are obtained.

[0131] Here, the main controller 600 is configured with a PID control algorithm model, which calculates the target input power value of each magnetic force generating device 200 based on the first parameter D_Y, the second parameter U_Y_Offset, the third parameter D_X, and the fourth parameter U_X_Offset, and sends the target input power value to the slave controller through control commands.

[0132] Here, the master controller 600 sends a first control command I1 to the first slave controller 701, the master controller 600 sends a second control command I2 to the second slave controller 702, the master controller 600 sends a third control command I3 to the third slave controller 703, and the master controller 600 sends a fourth control command I4 to the fourth slave controller 704.

[0133] Step 511: Based on the first control command I1, the second control command I2, the third control command I3 and the fourth control command I4, control the input power supply of the magnetic force generating device.

[0134] Here, the first slave controller 701 controls the input power of the first magnetic force generator 201 based on the first control command I1, the second slave controller 702 controls the input power of the second magnetic force generator 202 based on the second control command I2, the third slave controller 703 controls the input power of the third magnetic force generator 203 based on the third control command I3, and the fourth slave controller 704 controls the input power of the fourth magnetic force generator 204 based on the fourth control command I4.

[0135] Here, steps 503 to 511 can be performed during the process of the suspension plate assembly suspending and rising, or after the suspension plate assembly suspends at a set height at the air inlet 101.

[0136] In an exemplary embodiment, the control module of the air conditioner may be implemented by one or more application-specific integrated circuits (ASICs), DSPs, programmable logic devices (PLDs), complex programmable logic devices (CPLDs), field-programmable gate arrays (FPGAs), general-purpose processors, controllers, microcontrollers (MCUs), microprocessors, or other electronic components to perform the aforementioned method.
