Description

Technical Field

[0001] This application relates to, but is not limited to, the field of air handling equipment technology, specifically to an air conditioner and its control method and control device. Background Technology

[0002] In related technologies, air conditioners are equipped with electrostatic dust removal devices, which include high-voltage transformer components, dust collection components, and ion carbon brush components. The electrostatic dust removal device is installed on the air inlet side of the air conditioner. The ion carbon brush components discharge to charge airborne particles such as dust mites, which are then adsorbed onto the dust collection components, achieving the electrostatic dust removal effect. During use, some of the charge may be adsorbed onto sheet metal parts, motors, PCBs, and other structural components and deposited. If the amount of charge deposited reaches a certain value, it may cause electrostatic breakdown, damaging components such as motors and PCBs. Summary of the Invention

[0003] The technical problem to be solved by this application is to provide an air conditioner and its control method and control device, which helps to prevent the accumulation of charge generated by the electrostatic dust removal device inside the machine, leading to electrostatic breakdown.

[0004] This application provides an air conditioner, including: a casing with an air inlet and an air outlet; and an electrostatic dust removal device, including a separately configured discharge module and an electrostatic adsorption module; the discharge module includes a discharge component located at the air outlet and configured to discharge; the electrostatic adsorption module includes an electrostatic adsorption component located at the air inlet and configured to generate an adsorption electric field.

[0005] In related technologies, electrostatic dust removal devices are installed at the air inlet, and many of the generated charged particles are sucked into the air duct, causing charge to accumulate on components such as motors and PCBs inside the air conditioner, leading to electrostatic safety issues. However, the air conditioner provided in this application embodiment uses a separate electrostatic dust removal device consisting of two functional modules: a discharge module and an electrostatic adsorption module. Since the discharge component of the discharge module is located at the air outlet, the charged particles generated by the discharge component are directly blown to the outside of the air conditioner instead of entering the interior. This prevents the rapid accumulation of charge on components such as motors and PCBs inside the air conditioner, thus helping to avoid electrostatic breakdown in these components. The charged particles blown to the outside of the air conditioner diffuse in the air and can combine with particles such as dust mites, becoming charged. These charged particles then flow back to the air inlet of the air conditioner and are adsorbed and deposited on the electrostatic adsorption component, thereby achieving the electrostatic dust removal function.

[0006] Furthermore, the discharge component can generate charged particles (such as electrons, positive ions, and negative ions) as well as other high-energy particles (such as hydroxyl radicals). These substances can kill bacteria and viruses, thus achieving sterilization. Therefore, some products, in addition to installing an electrostatic dust removal device at the air inlet, also have a separate discharge module at the air outlet to achieve sterilization, resulting in a complex air conditioner structure and high cost. However, the embodiment of this application divides the electrostatic dust removal device into two parts, utilizing the discharge component of the electrostatic dust removal device to achieve sterilization, thereby eliminating the need for an additional discharge module. It combines dust removal and sterilization functions, simplifying the air conditioner structure and reducing costs.

[0007] This application also provides a control method applied to an air conditioner as described in the above embodiments, the control method comprising:

[0008] The target purification mode is determined, and the types of target purification modes include dust removal mode and sterilization mode;

[0009] The electrostatic dust removal device is controlled according to the determined target purification mode.

[0010] This application also provides a control device, including a processor and a memory storing a computer program, wherein the processor executes the computer program to implement the steps of the control method as described in the above embodiments. Attached Figure Description

[0031] The principles and features of this application are described below with reference to the accompanying drawings. The examples given are only for explaining this application and are not intended to limit the scope of this application.

[0032] like Figures 1 to 7 As shown in the figure, this application provides an air conditioner, including: a housing 1 and an electrostatic dust removal device.

[0033] Among them, such as Figures 1 to 3 As shown, the casing 1 has an air inlet 11 and an air outlet 12. The electrostatic dust removal device includes a separately configured discharge module 2 and an electrostatic adsorption module 3. The discharge module 2 includes a discharge component 21, which is located at the air outlet 12 and configured to discharge. The electrostatic adsorption module 3 includes an electrostatic adsorption component 31, which is located at the air inlet 11 and configured to generate an adsorption electric field.

[0034] In related technologies, the electrostatic dust removal device is located at the air inlet 11. Many of the generated charged particles are drawn into the air duct, causing charge to accumulate on components such as the motor and PCB inside the air conditioner, leading to electrostatic safety issues. However, the air conditioner provided in this application embodiment uses a separate electrostatic dust removal device consisting of two functional modules: a discharge module 2 and an electrostatic adsorption module 3. Since the discharge component 21 of the discharge module 2 is located at the air outlet 12, the charged particles generated by the discharge component 21 are directly blown towards the outside of the air conditioner. Figure 7 As shown, instead of entering the air conditioner's interior, the charged particles are directed towards the air inlet 11, thus preventing the rapid accumulation of charge on components such as the motor and PCB inside the air conditioner and helping to avoid electrostatic discharge problems. The charged particles blown towards the outside of the air conditioner diffuse in the air and can combine with particles such as dust mites, causing them to become charged. These charged dust mites then flow back towards the air inlet 11. Figure 7 As shown, the particles can be adsorbed by the electrostatic adsorption component 31 and deposited on the electrostatic adsorption component 31, thereby realizing the electrostatic dust removal function.

[0035] Furthermore, the discharge component 21 can generate charged particles (such as electrons, positive ions, negative ions, etc.) and other high-energy particles (such as hydroxyl radicals, etc.). These substances can kill bacteria and viruses, thus achieving sterilization. Therefore, some products, in addition to setting an electrostatic dust removal device at the air inlet 11, also set a separate discharge module 2 at the air outlet 12 to achieve sterilization, resulting in a complex air conditioner structure and high cost. However, the embodiment of this application divides the electrostatic dust removal device into two parts, and can use the discharge component 21 of the electrostatic dust removal device to achieve sterilization, thereby eliminating the need for the additional discharge module 2, and combining dust removal and sterilization functions, which helps to simplify the structure of the air conditioner and reduce costs.

[0036] In some embodiments, the discharge module 2 can be a standard component shipped with the entire unit to ensure that the air conditioner has an air purification function. The electrostatic adsorption module 3 can be an optional component and sold separately. Alternatively, the electrostatic adsorption module 3 can also be a standard component shipped with the entire unit.

[0037] In some exemplary embodiments, the air conditioner also includes an electronic control device 4, such as... Figure 2 and Figure 3 As shown. The electronic control device 4 is equipped with a power output terminal 41, such as... Figures 11 to 13 As shown. The electrostatic dust removal device has a power input terminal, which is configured to be electrically connected to the power output terminal 41. The discharge module 2 is electrically connected to the electrostatic adsorption module 3. The discharge module 2 has a first input terminal 223, and the electrostatic adsorption module 3 has a second input terminal 325. The first input terminal 223 or the second input terminal 325 forms the power input terminal. The power output terminal 41 can be a low-voltage interface, and the power input terminal can also be a low-voltage interface. The power input terminal and the power output terminal 41 can be electrically connected via a cable 5. The electrical control device 4 can be an electrical control box.

[0038] In this way, the electronic control device 4 only needs to be equipped with a single power interface to supply power to both the discharge module 2 and the electrostatic adsorption module 3 (equivalent to the discharge module 2 and the electrostatic adsorption module 3 sharing a single power interface). This simplifies the circuit and interface structure of the electronic control device 4, thereby reducing its size and cost. Furthermore, the fact that the discharge module 2 and the electrostatic adsorption module 3 share a single power interface allows them to be turned on and off simultaneously and controlled together, which simplifies the air conditioner's electronic control program.

[0039] In other embodiments, the electronic control device 4 is provided with two power interfaces, which are electrically connected to the discharge module 2 and the electrostatic adsorption module 3, respectively.

[0040] In some exemplary embodiments, such as Figure 3 As shown, the discharge module 2 further includes a first power supply module 22, and the electrostatic adsorption module 3 further includes a second power supply module 32. The first power supply module 22 is used to convert the low-voltage electricity output by the electronic control device 4 into high-voltage electricity to supply the discharge component 21. The second power supply module 32 is used to convert the low-voltage electricity output by the electronic control device 4 into high-voltage electricity to supply the electrostatic adsorption component 31.

[0041] In some embodiments, such as Figure 3As shown, the first power supply module 22 includes a first high-voltage transformer 221. The first high-voltage transformer 221 has a first output terminal (not shown) and a first input terminal 223. The first output terminal is electrically connected to the discharge assembly 21 so that the first high-voltage transformer 221 can supply power to the discharge assembly 21. The first input terminal 223 can be a low-voltage input port, and the first output terminal can be a high-voltage output port. The first high-voltage transformer 221 can apply the required high-voltage electricity to the discharge assembly 21, enabling the discharge assembly 21 to operate efficiently.

[0042] The second power supply module 32 includes an adapter 322 and a second high-voltage transformer 321. The adapter 322 has a second output terminal (not shown in the figure), a third output terminal 326, and a second input terminal 325, as shown below. Figure 11 As shown. The second input terminal 325 forms the power input terminal. The second output terminal is electrically connected to the input terminal of the second high-voltage transformer 321, and the output terminal of the second high-voltage transformer 321 (i.e. Figure 10 The electrical connector 323 is configured to be electrically connected to the electrostatic adsorption assembly 31 so that the second high-voltage transformer 321 can supply power to the electrostatic adsorption assembly 31. The third output terminal 326 is configured to be electrically connected to the first input terminal 223. The second input terminal 325 can be a low-voltage input port, the second output terminal can be a low-voltage output port, and the third output terminal 326 can be a low-voltage output port. The second high-voltage transformer 321 can apply the required high-voltage electricity to the electrostatic adsorption assembly 31 so that the electrostatic adsorption assembly 31 can work efficiently. The third output terminal 326 and the first input terminal 223 can be electrically connected by mating connectors or by wire 5.

[0043] Among them, such as Figure 11 As shown, the first input terminal 223 can be configured as an external port of the first power supply module 22. The second input terminal 325, the third output terminal 326, and the output terminal of the second high-voltage transformer 321 (i.e., Figure 10 The electrical connector 323 can be configured as an external port of the second power supply module 32, facilitating connection with the electronic control device 4, the first power supply module 22, and the electrostatic adsorption component 31. The second output terminal and the input terminal of the second high-voltage transformer 321 can be configured as internal ports of the second power supply module 32, enabling electrical connection within the second power supply module 32.

[0044] In this scheme, the discharge module 2 is not directly electrically connected to the electronic control device 4, but indirectly electrically connected to the electronic control device 4 through the adapter 322 of the electrostatic adsorption module 3, realizing the low-voltage series connection of the two functional modules. Since the discharge module 2 and the electrostatic adsorption module 3 are each equipped with a high-voltage transformer, high-voltage circuits can be set separately so that the discharge function and the electrostatic adsorption function can give full play to their respective advantages, thereby improving the dust removal and sterilization functions. For example, the first high-voltage transformer 221 can apply sinusoidal high-voltage electricity to the discharge component 21, or different high-voltage circuits can be set to adapt to different sub-discharge components 21 (such as the first sub-discharge component 21 and the second sub-discharge component 21 described below). The second high-voltage transformer 321 can apply constant voltage DC electricity to the electrostatic adsorption component 31 to keep the generated electrostatic field constant, so as to achieve efficient dust collection.

[0045] When the electrostatic adsorption module 3 is set as an optional module, the first input terminal 223 of the discharge module 2 can be connected to the power output terminal 41 of the electronic control device 4 via the cable 5 at the factory. Figure 2 As shown. When a user purchases the electrostatic adsorption module 3, the wire 5 of the discharge module 2 can be disconnected from the electronic control device 4. The electrostatic adsorption module 3 can then be installed, and the second input terminal 325 can be connected to the power output terminal 41 of the electronic control device 4. Then, the first input terminal 223 of the discharge module 2 can be connected to the third output terminal 326 of the electrostatic adsorption module 3 via the wire 5. Figure 3 As shown.

[0046] In other embodiments, such as Figure 12 As shown, the first power supply module 22 includes a first adapter 222 and a first high-voltage transformer 221. The first adapter 222 has a first output terminal (not shown), a second output terminal 224, and a first input terminal 223. The first output terminal is electrically connected to the input terminal of the first high-voltage transformer 221, and the output terminal of the first high-voltage transformer 221 is electrically connected to the discharge assembly 21 so that the first high-voltage transformer 221 can supply power to the discharge assembly 21. The first input terminal 223 forms a power input terminal. The first input terminal 223 can be a low-voltage input port, the first output terminal can be a low-voltage output port, and the second output terminal 224 can be a low-voltage output port. The first high-voltage transformer 221 can apply the required high-voltage electricity to the discharge assembly 21 so that the discharge assembly 21 can operate efficiently.

[0047] The second power supply module 32 is provided with a second adapter 324 and a second high-voltage transformer 321. The second adapter 324 is provided with a third output terminal (not shown in the figure) and a second input terminal 325. The third output terminal is electrically connected to the input terminal of the second high-voltage transformer 321, and the output terminal of the second high-voltage transformer 321 (i.e., Figure 12The electrical connector 323 is configured to be electrically connected to the electrostatic adsorption assembly 31 so that the second high-voltage transformer 321 can supply power to the electrostatic adsorption assembly 31. The second input terminal 325 is configured to be electrically connected to the second output terminal 224. The second input terminal 325 can be a low-voltage input port, and the third output terminal can be a low-voltage output port. The second high-voltage transformer 321 can apply the required high-voltage electricity to the electrostatic adsorption assembly 31 so that the electrostatic adsorption assembly 31 can work efficiently. The second output terminal 224 is configured to be electrically connected to the second input terminal 325 through a connector or through a wire 5.

[0048] Among them, such as Figure 12 As shown, the first input terminal 223 and the second output terminal 224 can be configured as external ports of the first power supply module 22, facilitating the connection between the first power supply module 22 and the electronic control device 4 and the second power supply module 32. The second input terminal 325 is the output terminal of the second high-voltage transformer 321 (i.e., Figure 12 The electrical connector 323 can be configured as an external port of the second power supply module 32, facilitating the docking of the second power supply module 32 with the electrostatic adsorption component 31. The first output terminal and the input terminal of the first high-voltage transformer 221 can be configured as internal ports of the first power supply module 22, enabling electrical connection within the first power supply module 22.

[0049] In this scheme, the electrostatic adsorption module 3 is not directly connected to the electronic control device 4, but is indirectly connected to the electronic control device 4 through the first adapter of the discharge module 2, realizing the weak current series connection of the two functional modules. Since the discharge module 2 and the electrostatic adsorption module 3 are each equipped with a high-voltage transformer, high-voltage circuits can be set separately so that the discharge function and the electrostatic adsorption function can give full play to their respective advantages, thereby improving the dust removal and sterilization functions. For example, the first high-voltage transformer 221 can apply sinusoidal high-voltage electricity to the discharge component 21, or different high-voltage circuits can be set to adapt to different sub-discharge components 21 (such as the first sub-discharge component 21 and the second sub-discharge component 21 described below). The second high-voltage transformer 321 can apply constant voltage DC electricity to the electrostatic adsorption component 31 to keep the generated electrostatic field constant, so as to achieve efficient dust collection.

[0050] In other exemplary embodiments, such as Figure 13As shown, the discharge module 2 also includes a first power supply module 22, which has a first adapter 222 and a first high-voltage transformer 221. The first adapter 222 has a first input terminal 223, which forms a power input terminal. The output terminal of the first adapter 222 is electrically connected to the input terminal of the first high-voltage transformer 221. The first high-voltage transformer 221 has a first output terminal (not shown) and a second output terminal 224. The first output terminal is electrically connected to the discharge assembly 21 so that the first high-voltage transformer 221 can supply power to the discharge assembly 21. The first input terminal 223 can be a low-voltage input port. The first output terminal can be a high-voltage output port, and the second output terminal can also be a high-voltage output port. The first high-voltage transformer 221 can apply the required high-voltage electricity to the discharge assembly 21 so that the discharge assembly 21 can operate efficiently.

[0051] The electrostatic adsorption module 3 also includes a second power supply module 32, which is equipped with a second adapter 322. The second adapter 322 is equipped with a second input terminal 325 and a third output terminal 326 (i.e., ... Figure 13 The second input terminal 325 is configured to be electrically connected to the second output terminal 224 and the third output terminal 326 (i.e., the electrical connector 323 in the middle). Figure 13 The electrical connector 323 is configured to be electrically connected to the electrostatic adsorption assembly 31 so that the first high-voltage transformer 221 can supply power to the electrostatic adsorption assembly 31. The second output terminal 224 can be a high-voltage output port, and the third output terminal 326 can be a high-voltage output port. The first high-voltage transformer 221 can apply high voltage to the electrostatic adsorption assembly 31 to generate an adsorption electric field in the electrostatic adsorption assembly 31.

[0052] The first input terminal 223 and the second output terminal 224 can be configured as external ports of the first power supply module 22, facilitating connection between the first power supply module 22 and the electronic control device 4 and the second power supply module 32. The second input terminal 325 and the third output terminal 326 can be configured as external ports of the second power supply module 32, facilitating connection between the second power supply module 32 and the electrostatic adsorption component 31. The first output terminal and the input terminal of the first high-voltage transformer 221 can be configured as internal ports of the first power supply module 22, enabling electrical connection within the first power supply module 22.

[0053] In this solution, since the electrostatic adsorption module 3 does not have a separate high-voltage pack, but shares the first high-voltage pack 221 with the discharge component 21, one high-voltage pack is eliminated, which helps to reduce the size of the second power supply module 32, thus saving installation space and reducing costs.

[0054] When the electrostatic adsorption module 3 is set as an optional module, the first input terminal 223 of the discharge module 2 can be connected to the power output terminal 41 of the electronic control device 4 via the cable 5 at the factory. When the user purchases the electrostatic adsorption module 3, the electrostatic adsorption module 3 can be installed, and then the second input terminal of the electrostatic adsorption module 3 can be connected to the second output terminal of the discharge module 2 via the cable 5.

[0055] In some exemplary embodiments, such as Figure 3 As shown, the second power supply module 32 is fixed to the housing 1. The electrostatic adsorption component 31 is detachably connected to the housing 1 and also detachably connected to the second power supply module 32, for example, through snap-fit ​​connections, fastener connections, or plug-in connections. This facilitates the disassembly and cleaning of the electrostatic adsorption component 31 and is beneficial for its long-term use.

[0056] In some exemplary embodiments, the second power supply module 32 is provided with an electrical plug 323 (e.g., Figure 4 (As shown) and a micro switch. The electrical plug 323 is configured to engage with the electrostatic adsorption component 31, allowing for electrical connection or disconnection between the electrostatic adsorption component 31 and the second power supply module 32 via plugging and unplugging. This is simple, convenient, safe, and reliable. The micro switch is triggered when the electrostatic adsorption component 31 is fully inserted to activate the circuit of the second power supply module 32, improving safety and preventing accidental triggering that could lead to safety hazards.

[0057] In some exemplary embodiments, such as Figure 4 As shown, the electrostatic adsorption assembly 31 includes a frame 311, an electrostatic dust collection plate 312 disposed on the frame 311, and a power-off pin 313 electrically connected to the electrostatic dust collection plate 312. The power-off pin 313 can be plugged into and unplugged into the electrical plug portion 323 of the second power supply module 32. The frame 311 can be detachably connected to the housing 1 through snap-fit ​​connection, fastener connection, plug-in connection, or other connection methods to facilitate the disassembly and cleaning of the electrostatic adsorption assembly 31.

[0058] In some exemplary embodiments, the power input terminal is configured to be detachably connected to the power output terminal 41. For example, the detachable connection can be achieved through a pluggable cable 5, which is simple and convenient to operate and safe and reliable.

[0059] In some exemplary embodiments, the gap between the discharge assembly 21 and the housing 1 is greater than 50 mm.

[0060] Since the housing 1 is a sheet metal part, it has a strong ability to adsorb charges. Therefore, the gap between the discharge component 21 and the housing 1 is set to be greater than 50mm, so that the discharge component 21 and the housing 1 are far apart. This makes it easier for the charged particles generated by the discharge component 21 to be quickly blown into the indoor space by the airflow, and not adsorbed onto the sheet metal parts such as the housing 1. This helps to improve the utilization rate of the charged particles generated by the discharge and improve the dust removal and sterilization efficiency.

[0061] Of course, the gap between the discharge assembly 21 and the housing 1 is not limited to the above range and can be adjusted as needed.

[0062] In some exemplary embodiments, the discharge component 21 includes a first sub-discharge component 21 and a second sub-discharge component 21. The first sub-discharge component 21 is configured to discharge under the action of negative high voltage direct current, and the second sub-discharge component 21 is configured to discharge under the action of high voltage with voltage variation (such as sinusoidal AC high voltage).

[0063] The first sub-discharge component 21 can generate a large number of electrons under the action of negative high voltage direct current. The electrons are captured by electrophilic oxygen molecules (O2) or water molecules (H2O) in the air to form Be (Biomimetic electronic) ions. The Be ions diffuse into the air and can actively capture and knock down suspended bacteria and viruses in the air, thereby achieving the sterilization function.

[0064] The second discharge component 21 can discharge under the influence of high voltage with voltage variations, generating a high-energy particle jet region containing a large number of electrons (e.g., electrons). - It contains a variety of bactericidal factors, including reactive oxygen species (ROS), reactive nitrogen species (RNS), charged particles, and free radicals (such as ·OH), which can effectively kill bacteria, viruses, and other microorganisms in the air.

[0065] Furthermore, the fusion of Be ions with high-energy jet particles can generate more high-energy electrons, which in turn generate more free radicals and high-energy particles. The combination of the two forms a synergistic effect, which can expand the scope of sterilization and virus removal, and improve the rate and effect of sterilization and virus removal.

[0066] The first sub-discharge component 21 generates negative Be ions, which can remain in the air for a longer time and are more stable, thus improving dust removal efficiency. The second sub-discharge component 21 generates high-energy jet particles, which are plasma and have good bactericidal properties, further enhancing the sterilization effect. The combination of these two components improves both dust removal and sterilization, achieving a dual optimization of both effects. Testing showed that the removal rate of influenza virus reached 99.9% within 1 hour, and the removal rate of dust mite allergens reached approximately 90% within 2 hours.

[0067] In some exemplary embodiments, such as Figure 6 As shown, the first sub-discharge assembly 21 includes an ion carbon brush head 211. The number of ion carbon brush heads 211 can be multiple, such as two, three or more.

[0068] like Figure 6 As shown, the second sub-discharge assembly 21 includes a discharge electrode 212 and a counter electrode 213 arranged at relatively intervals. The discharge electrode 212 includes a needle electrode 2121, and the counter electrode 213 has a through hole 2131 corresponding to the needle electrode 2121. This allows a three-dimensional discharge space to be formed between the discharge electrode 212 and the counter electrode 213, which is beneficial for increasing the electric field strength and the density of high-energy particles, thereby improving the sterilization effect.

[0069] The discharge electrode 212 may also include a plate-shaped substrate. The number of needle electrodes 2121 can be multiple, and these needle electrodes 2121 can be spaced apart on the plate-shaped substrate. By electrically connecting the plate-shaped substrate to the second power supply module 322, the multiple needle electrodes 2121 can be energized simultaneously. The counter electrode 213 can be a plate-shaped electrode, and the number of through holes 2131 can be equal to and correspond one-to-one with the number of needle electrodes 2121.

[0070] In some exemplary embodiments, such as Figure 5 and Figure 6 As shown, the discharge module 2 also includes a mounting base 23 and a protective cover 24. The first sub-discharge assembly 21 and the second sub-discharge assembly 21 are mounted on the mounting base 23. The protective cover 24 covers the mounting base 23 and encloses the second sub-discharge assembly 21, and the protective cover 24 has a perforated vent 241. This improves safety performance and prevents accidental contact with the second sub-discharge assembly 21 from causing a safety accident. The first sub-discharge assembly 21 can be located outside the protective cover 24. For example, the first sub-discharge assembly 21 may include two ion carbon brush heads 211, with the two ion carbon brush heads 211 located on opposite sides of the protective cover 24.

[0071] In some exemplary embodiments, such as Figure 5 and Figure 6As shown, the mounting base 23 includes a base body 231 and a cover body 232. The base body 231 can be integrally formed with the housing of the first high-voltage transformer 221, and the cover body 232 can be integrally formed with the cover of the first high-voltage transformer 221. The cover body 232 is connected to the base body 231 by means of snap-fit, fasteners, etc. The base body 231 can be a one-piece structure (e.g., an injection-molded one-piece structure), and the cover body 232 can be a one-piece structure. The ion carbon brush head 211 can be fixed to the mounting base 23 by means of snap-fit, fastener connection, etc. The discharge electrode 212 and the counter electrode 213 can be fixed to the mounting base 23 by means of snap-fit, fastener connection, etc.

[0072] In the embodiments of this application, the air conditioner can be the indoor unit of a split air conditioner (such as a duct-type indoor unit), or it can be an air conditioner unit including an indoor unit and an outdoor unit, or it can be an integrated air conditioner.

[0073] like Figure 8 As shown in the embodiments of this application, a control method is also provided, applied to the air conditioner of any of the above embodiments. The control method includes:

[0074] Step S202: Determine the target purification mode, which includes dust removal mode and sterilization mode;

[0075] Step S204: Control the electrostatic dust removal device according to the determined target purification mode.

[0076] The control method provided in this application embodiment can control the electrostatic dust removal device according to the determined target purification mode, providing users with purification functions such as dust removal and sterilization, which can meet different user needs and improve the user experience.

[0077] The method for determining the target purification mode is unrestricted. It can be determined by external commands, such as users selecting the corresponding purification mode via remote control, mobile terminal (e.g., mobile phone, computer, smartwatch app), control panel, etc. Alternatively, it can be automatically determined based on detection results, such as automatically determining the appropriate purification mode based on indoor air quality test results.

[0078] In some exemplary embodiments, controlling the electrostatic precipitator according to a determined target purification mode includes:

[0079] Based on the target purification mode being dust removal mode, the electrostatic dust removal device is controlled to be turned on intermittently.

[0080] Based on the target purification mode being sterilization mode, the electrostatic precipitator is controlled to operate continuously for a first set time before being shut down. The first set time can be, but is not limited to, 2 hours (and can also be less than 2 hours). Therefore, the electrostatic precipitator can be restarted after being shut down for 6 hours, thus meeting the requirement that the cumulative sterilization time within 8 hours does not exceed 2 hours. Figure 9 As shown.

[0081] Since the electrostatic dust removal device provided in this application embodiment also has a sterilization function, and current national standards and industry standards have limitations on the operating time of the sterilization function (e.g., cumulative sterilization should not exceed 2 hours within 8 hours), it is necessary to control the operating time of the electrostatic dust removal device. In addition, indoor bacteria are short-term limits and will not grow in the short term after rapid disinfection; while the dust removal function is affected by factors such as opening windows and gaps, and fresh air will be continuously replenished, so there is a need for long-term dust removal.

[0082] Therefore, when the target purification mode is dust removal mode, the electrostatic precipitator can be controlled to operate intermittently to meet the needs of long-term dust removal, but the total cumulative operating time will not exceed the limit. Furthermore, sterilization also occurs during dust removal mode operation, thus indirectly achieving the effect of long-term sterilization.

[0083] When the target purification mode is sterilization mode, the electrostatic dust removal device can be controlled to run continuously for a first set time and then stop working. This rapid sterilization meets the sterilization requirements without exceeding the operating time limit. The above control logic balances the time constraints of sterilization with the need for long-term dust removal, which helps maintain clean indoor air and continuously purify newly introduced unclean air, thus optimizing the overall practical application effect of sterilization and dust removal.

[0084] In some exemplary embodiments, controlling the electrostatic precipitator to operate intermittently includes:

[0085] First, control the electrostatic precipitator to keep running for a second set time. Then, control the electrostatic precipitator to open intermittently with a cycle of stopping for a third set time and running for a fourth set time.

[0086] The second set duration is longer than the fourth set duration.

[0087] First, control the electrostatic dust removal device to keep running for the second set time. This can quickly purify existing indoor pollutants such as dust mites. Subsequent periodic intermittent operation only needs to purify newly entering unclean air, so the duration of each operation does not need to be too long.

[0088] In one example, the second set duration can be, but is not limited to, 30 minutes, the third set duration can be, but is not limited to, 2 minutes, and the fourth set duration can be, but is not limited to, 1 minute. The electrostatic precipitator can be shut down after running for a cumulative total of 120 minutes.

[0089] In another example, the second set duration can be, but is not limited to, 30 minutes; the third set duration can be, but is not limited to, 50 minutes; and the fourth set duration can be, but is not limited to, 10 minutes. Then, the cumulative running time over 8 hours is 120 minutes. Figure 10 As shown.

[0090] In some exemplary embodiments, the air conditioner further includes a fan, and the control method further includes:

[0091] Based on the air conditioner entering dust removal mode from the off state, the fan is controlled to start operation at the set speed;

[0092] Based on the air conditioner switching from the on state to the dust removal mode, the fan is controlled to maintain the current state;

[0093] Based on the air conditioner entering sterilization mode from the off state, the fan is controlled to start and run at the highest speed.

[0094] Based on the air conditioner switching from the on state to the sterilization mode, the fan is controlled to maintain the current state.

[0095] When switching from the on state to dust removal or sterilization mode, the fan continues to operate in the previous mode (such as cooling or heating) to avoid affecting other functions. Users can adjust the fan speed or switch to other modes (such as cooling or heating) midway through the process without affecting the normal operation of the dust removal function. After the allotted time, the electrostatic precipitator shuts off, and other functions continue to operate.

[0096] When the device is switched off, it enters sterilization mode, controlling the fan to start and run at the highest speed for rapid and efficient purification. Users can adjust the fan speed or switch to other modes (such as cooling or heating) during operation without affecting the normal operation of the dust removal function.

[0097] When the device switches from shutdown to dust removal mode, the fan is controlled to start at the set speed for rapid and efficient purification. Since the electrostatic precipitator operates intermittently over a relatively long period, the set speed does not need to be too high; for example, it can be around 60% of the default starting speed. Users can adjust the fan speed or switch to other modes (such as cooling or heating) during operation without affecting the normal operation of the dust removal function.

[0098] This application also provides a control device, including a processor and a memory storing a computer program. When the processor executes the computer program, it implements the steps of any of the control methods described in the above embodiments, and thus has all the above-mentioned beneficial effects, which will not be repeated here.

[0099] This application also provides a computer-readable storage medium storing a computer program. When the computer program is executed by a processor, it implements the steps of any of the control methods described in the above embodiments, and thus has all the above-mentioned beneficial effects, which will not be repeated here.

[0100] The processor may be an integrated circuit chip with signal processing capabilities. The aforementioned processor can be a general-purpose processor, including a Central Processing Unit (CPU), a Network Processor (NP), etc.; it can also be a Digital Signal Processor (DSP), an Application-Specific Integrated Circuit (ASIC), an On-Premises Programmable Gate Array (FPGA), or other programmable logic devices, discrete gate or transistor logic devices, or discrete hardware components. It can implement or execute the methods, steps, and logic block diagrams disclosed in the embodiments of this invention. The general-purpose processor can be a microprocessor or any conventional processor.

[0101] In summary, the air conditioner and its control method and device provided in this application divide the electrostatic dust removal device into two functional modules: a discharge module and an electrostatic adsorption module. The discharge module is located at the air outlet, preventing the generated Be ions and high-energy jet ions from being drawn into the air duct and then blown out. This helps prevent ion attenuation caused by adsorption on sheet metal and also solves the problem of excessively rapid accumulation of static electricity on the sheet metal, ensuring that static electricity does not reach the level of electrostatic breakdown. This solves the problem of electrostatic breakdown of components such as motors and PCBs, and indirectly achieves the effect of long-term operation of the sterilization function (i.e., long-term sterilization through dust removal mode). The electrostatic adsorption module is designed at the air inlet for easy dust capture and disassembly for cleaning. Through improvements in the control method, the sterilization and dust removal effects can achieve over 99% efficiency throughout the entire cycle, optimizing the compatibility of the two functions.
