Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of air treatment equipment, in particular to an air conditioner. BACKGROUND

[0002] In the related art, an air conditioner is provided with an electrostatic dust removal device. The electrostatic dust removal device includes a high-voltage pack assembly, a dust collection assembly, and an ion carbon brush assembly. The electrostatic dust removal device is installed at the air inlet side of the air conditioner. The ion carbon brush assembly is used to discharge electricity to charge dust mites and other particles in the air, and then the dust mites and other particles are adsorbed onto the dust collection assembly to achieve the electrostatic dust removal effect. During use, part of the electric charge is adsorbed onto metal parts, motors, PCBs, and other structural parts and deposited. When the amount of deposited electric charge reaches a certain value, it may cause electrostatic breakdown, damaging the motors, PCBs, and other components. CONTENT OF THE UTILITY MODEL

[0003] The technical problem to be solved by the present application is to provide an air conditioner that can prevent the electric charge generated by the electrostatic dust removal device from accumulating inside the machine and causing electrostatic breakdown.

[0004] The air conditioner provided by the present application comprises a casing, an air inlet, and an air outlet. The casing is provided with an electrostatic dust removal device, which includes a discharge module and an electrostatic adsorption module. The discharge module includes a discharge assembly, which is arranged at the air outlet and is configured to discharge electricity. The electrostatic adsorption module includes an electrostatic adsorption assembly, which is arranged at the air inlet and is configured to generate an adsorption electric field.

[0005] In the related art, the electrostatic dust removal device is arranged at the air inlet. Many charged particles generated by the electrostatic dust removal device are sucked into the air duct, causing the electric charge to deposit on the motors, PCBs, and other components inside the air conditioner, which may cause electrostatic safety problems. The air conditioner provided by the present application is provided with two functional modules, i.e., the discharge module and the electrostatic adsorption module. The discharge assembly of the discharge module is arranged at the air outlet. The charged particles generated by the discharge assembly are directly blown to the outside of the air conditioner instead of entering the air conditioner. This can prevent the electric charge from rapidly accumulating on the motors, PCBs, and other components inside the air conditioner, thereby preventing the motors, PCBs, and other components from being electrostatically broken down. The charged particles blown to the outside of the air conditioner can diffuse in the air and combine with dust mites and other particles in the air to charge them. The charged dust mites and other particles can then flow back to the air inlet of the air conditioner and be adsorbed by the electrostatic adsorption assembly to deposit on the electrostatic adsorption assembly, 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. Attached Figure Description

[0027] The principles and features of the present application are described below in combination with the figures, and the examples are only used to explain the present application, and are not used to limit the scope of the present application.

[0028] As shown in Figures 1 to 7 , the present application provides an air conditioner, which comprises a housing 1 and an electrostatic precipitator.

[0029] Among them, as shown in Figures 1 to 3 , the housing 1 is provided with an air inlet 11 and an air outlet 12. The electrostatic precipitator comprises a discharge module 2 and an electrostatic adsorption module 3 arranged separately. The discharge module 2 comprises a discharge assembly 21, which is arranged at the air outlet 12 and is configured to discharge. The electrostatic adsorption module 3 comprises an electrostatic adsorption assembly 31, which is arranged at the air inlet 11 and is configured to generate an adsorption electric field.

[0030] In the related art, the electrostatic dust removal device is arranged at the air inlet 11, and many generated charged particles are sucked into the air duct, causing the charge to be deposited on the motor, PCB and other components inside the air conditioner, resulting in an electrostatic safety problem. The air conditioner provided in the embodiments of the present application sets the electrostatic dust removal device into two functional modules, i.e., the discharge module 2 and the electrostatic adsorption module 3. Since the discharge assembly 21 of the discharge module 2 is located at the air outlet 12, the charged particles generated by the discharge of the discharge assembly 21 are directly blown to the outside of the air conditioner, as shown in FIG. 2, instead of entering the inside of the air conditioner, thereby avoiding the rapid accumulation of the charge on the motor, PCB and other components inside the air conditioner, and thus facilitating the avoidance of the electrostatic breakdown of the motor, PCB and other components. Figure 7 Figure 7 The charged particles blown to the outside of the air conditioner diffuse in the air, can combine with the dust mites and other particles in the air to charge them, and the charged dust mites and other particles flow back to the air inlet 11 of the air conditioner, as shown in FIG. 3, and can be adsorbed by the electrostatic adsorption assembly 31 to be deposited on the electrostatic adsorption assembly 31, thereby realizing the electrostatic dust removal function.

[0031] In addition, the discharge of the discharge assembly 21 can generate charged particles (such as electrons, positive ions, negative ions, etc.) and other high-energy particles (such as hydroxyl radicals, etc.), which can kill bacteria, viruses and the like, thereby realizing the sterilization function. Therefore, some products set the electrostatic dust removal device at the air inlet 11 of the air conditioner and separately set the discharge module 2 at the air outlet 12 of the air conditioner to realize the sterilization function, resulting in a complex structure of the air conditioner and high cost. The embodiments of the present application divide the electrostatic dust removal device into two parts, and can utilize the discharge assembly 21 of the electrostatic dust removal device to realize the sterilization function, thereby eliminating the need for the additional discharge module 2, and the electrostatic dust removal device has both the dust removal function and the sterilization function, which is conducive to simplifying the structure of the air conditioner and reducing the cost.

[0032] In some embodiments, the discharge module 2 can be set as a standard module, which is shipped with the whole machine to ensure that the air conditioner has the air purification function. The electrostatic adsorption module 3 can be set as an optional module, which can be sold separately. Alternatively, the electrostatic adsorption module 3 can also be set as a standard module, which is shipped with the whole machine.

[0033] In some exemplary embodiments, the air conditioner further comprises an electric control device 4, as shown in FIG. 4 and FIG. 5. The electric control device 4 is provided with a power output end 41, as shown in FIG. 6. Figure 2 Figure 3 Figures 11 to 13 ​​​The electrostatic dust removal device is provided with a power input end which is arranged to be electrically connected with the power output end 41. The discharge module 2 is electrically connected with the electrostatic adsorption module 3, the discharge module 2 is provided with a first input end 223, the electrostatic adsorption module 3 is provided with a second input end 325, and the first input end 223 or the second input end 325 forms the power input end. The power output end 41 can be a weak current interface, and the power input end can be a weak current interface. The power input end and the power output end 41 can be electrically connected through the wire body 5. The electric control device 4 can be an electric control box.

[0034] In this way, the electric control device 4 only needs to be provided with one power interface, and the discharge module 2 and the electrostatic adsorption module 3 can be powered together (equivalent to the discharge module 2 and the electrostatic adsorption module 3 sharing one power interface), thereby being beneficial to simplify the circuit structure and the interface structure of the electric control device 4, which is beneficial to reduce the size of the electric control device 4 and reduce the cost. Moreover, the discharge module 2 and the electrostatic adsorption module 3 share one power interface, and can be turned on and turned off together and controlled together, which is beneficial to simplify the electric control program of the air conditioner.

[0035] In other embodiments, the electric control device 4 is provided with two power interfaces which are respectively electrically connected with the discharge module 2 and the electrostatic adsorption module 3.

[0036] In some exemplary embodiments, as shown in Figure 3 The discharge module 2 further comprises a first power supply module 22, and the electrostatic adsorption module 3 further comprises a second power supply module 32. The first power supply module 22 is used to convert the low-voltage electricity output by the electric control device 4 into high-voltage electricity to supply the discharge assembly 21. The second power supply module 32 is used to convert the low-voltage electricity output by the electric control device 4 into high-voltage electricity to supply the electrostatic adsorption assembly 31.

[0037] In some embodiments, as shown in Figure 3 The first power supply module 22 is provided with a first high-voltage pack 221. The first high-voltage pack 221 is provided with a first output end (not shown in the figure) and a first input end 223. The first output end is electrically connected with the discharge assembly 21 so that the first high-voltage pack 221 can supply power to the discharge assembly 21. The first input end 223 can be a weak current input port, and the first output end can be a high-voltage output port. The first high-voltage pack 221 can load the required high-voltage electricity to the discharge assembly 21 to make the discharge assembly 21 work efficiently.

[0038] The second power supply module 32 is provided with an adapter 322 and a second high-voltage pack 321. The adapter 322 is provided with a second output end (not shown in the figure), a third output end 326 and a second input end 325, as shown in Figure 11 The second input end 325 forms the power input end. The second output end is electrically connected with the input end of the second high-voltage pack 321, and the output end of the second high-voltage pack 321 (i.e. Figure 10The electric plug 323 in the second high voltage pack 321 is arranged to be electrically connected with the electrostatic adsorption assembly 31 to enable the second high voltage pack 321 to supply power to the electrostatic adsorption assembly 31. The third output end 326 is arranged to be electrically connected with the first input end 223. The second input end 325 can be a weak current input port, the second output end can be a weak current output port, and the third output end 326 can be a weak current output port. The second high voltage pack 321 can load the required high voltage electricity to the electrostatic adsorption assembly 31 to enable the electrostatic adsorption assembly 31 to work efficiently. The third output end 326 and the first input end 223 can be electrically connected through the docking of the docking head, or can be electrically connected through the wire body 5.

[0039] As shown in Figure 11 , the first input end 223 can be arranged as an external port of the first power supply module 22. The second input end 325, the third output end 326, and the output end of the second high voltage pack 321 (i.e. the electric plug 323 in the second high voltage pack 321) can be arranged as external ports of the second power supply module 32, to facilitate docking with the electric control device 4, the first power supply module 22, and the electrostatic adsorption assembly 31. The second output end and the input end of the second high voltage pack 321 can be arranged as internal ports of the second power supply module 32, to achieve electrical connection inside the second power supply module 32. Figure 10

[0040] In this scheme, the discharge module 2 is not directly electrically connected with the electric control device 4, but is indirectly electrically connected with the electric control device 4 through the adapter head 322 of the electrostatic adsorption module 3, to realize weak current series connection processing of the two functional modules. Since the discharge module 2 and the electrostatic adsorption module 3 are respectively provided with high voltage packs, high voltage circuits can be respectively arranged to enable the discharge function and the electrostatic adsorption function to fully exert their respective advantages, thereby improving the dust removal and sterilization functions. For example, the first high voltage pack 221 can load sinusoidal high voltage electricity to the discharge assembly 21, or different high voltage circuits can be arranged to adapt to different sub-discharge assemblies 21 (such as the first sub-discharge assembly 21 and the second sub-discharge assembly 21 described below). The second high voltage pack 321 can load constant voltage direct current to the electrostatic adsorption assembly 31 to enable the generated electrostatic field to remain constant, to realize efficient dust removal.

[0041] When the electrostatic adsorption module 3 is arranged as an optional module, the first input end 223 of the discharge module 2 can be connected to the power output end 41 of the electric control device 4 through the wire body 5 when leaving the factory, as shown in Figure 2 . When the user purchases the electrostatic adsorption module 3, the wire body 5 of the discharge module 2 can be disconnected from the electric control device 4, the electrostatic adsorption module 3 is mounted, the second input end 325 is connected to the power output end 41 of the electric control device 4, and then the first input end 223 of the discharge module 2 is connected to the third output end 326 of the electrostatic adsorption module 3 through the wire body 5, as shown in Figure 3 .

[0042] ​In other embodiments, as shown in Figure 12 The first power supply module 22 is provided with a first adapter 222 and a first high-voltage pack 221. The first adapter 222 is provided with a first output end (not shown in the figure), a second output end 224 and a first input end 223. The first output end is electrically connected with an input end of the first high-voltage pack 221, and an output end of the first high-voltage pack 221 is electrically connected with the discharge assembly 21 to enable the first high-voltage pack 221 to supply power to the discharge assembly 21. The first input end 223 forms a power input end. The first input end 223 can be a weak-current input port, the first output end can be a weak-current output port, and the second output end 224 can be a weak-current output port. The first high-voltage pack 221 can load the required high-voltage power to the discharge assembly 21 to enable the discharge assembly 21 to work with high efficiency.

[0043] The second power supply module 32 is provided with a second adapter 324 and a second high-voltage pack 321. The second adapter 324 is provided with a third output end (not shown in the figure) and a second input end 325. The third output end is electrically connected with an input end of the second high-voltage pack 321, and an output end (i.e. an electric plug 323 in Figure 12 The second high-voltage pack 321 is electrically connected with the electrostatic adsorption assembly 31 to enable the second high-voltage pack 321 to supply power to the electrostatic adsorption assembly 31. The second input end 325 is electrically connected with the second output end 224. The second input end 325 can be a weak-current input port, and the third output end can be a weak-current output port. The second high-voltage pack 321 can load the required high-voltage power to the electrostatic adsorption assembly 31 to enable the electrostatic adsorption assembly 31 to work with high efficiency. The second output end 224 is electrically connected with the second input end 325 through the docking of the adapters, or through the wire body 5.

[0044] As shown in Figure 12 The first input end 223 and the second output end 224 can be set as external ports of the first power supply module 22 to facilitate the docking of the first power supply module 22 with the electric control device 4 and the second power supply module 32. The second input end 325 and the output end of the second high-voltage pack 321 (i.e. the electric plug 323 in Figure 12 The second power supply module 32 can be docked with the electrostatic adsorption assembly 31. The first output end and the input end of the first high-voltage pack 221 can be set as internal ports of the first power supply module 22 to realize electrical connection inside the first power supply module 22.

[0045] In the scheme, the electrostatic adsorption module 3 is not directly connected with the electric control device 4, but is indirectly connected with the electric control device 4 through the first adapter of the discharge module 2, so as to realize the weak current series connection of the two functional modules. Since the discharge module 2 and the electrostatic adsorption module 3 are respectively provided with high-voltage packs, high-voltage circuits can be respectively arranged, so that the discharge function and the electrostatic adsorption function can fully exert their respective advantages, thereby improving the dust removal and sterilization functions. For example, the first high-voltage pack 221 can load sinusoidal high-voltage electricity to the discharge assembly 21, or different high-voltage circuits can be arranged to adapt to different sub-discharge assemblies 21 (such as the first sub-discharge assembly 21 and the second sub-discharge assembly 21 described below). The second high-voltage pack 321 can load constant-voltage direct current to the electrostatic adsorption assembly 31, so that the generated electrostatic field remains constant, so as to realize efficient dust removal.

[0046] In some other exemplary embodiments, as shown in Figure 13 The discharge module 2 further includes a first power supply module 22, and the first power supply module 22 is provided with a first adapter 222 and a first high-voltage pack 221. The first adapter 222 is provided with a first input end 223. The first input end 223 forms a power input end. The output end of the first adapter 222 is electrically connected with the input end of the first high-voltage pack 221. The first high-voltage pack 221 is provided with a first output end (not shown in the figure) and a second output end 224. The first output end is electrically connected with the discharge assembly 21, so that the first high-voltage pack 221 can supply power to the discharge assembly 21. The first input end can be a weak current input port. The first output end can be a high-voltage electricity output port, and the second output end can be a high-voltage electricity output port. The first high-voltage pack 221 can load the required high-voltage electricity to the discharge assembly 21, so that the discharge assembly 21 can work efficiently.

[0047] The electrostatic adsorption module 3 further includes a second power supply module 32, and the second power supply module 32 is provided with a second adapter 322. The second adapter 322 is provided with a second input end 325 and a third output end 326 (i.e. the electric plug 323 in Figure 13 The second input end 325 is arranged to be electrically connected with the second output end 224, and the third output end 326 (i.e. the electric plug 323 in Figure 13 The second output end 224 can be a high-voltage electricity output port, and the third output end 326 can be a high-voltage electricity output port. The first high-voltage pack 221 can load high-voltage electricity to the electrostatic adsorption assembly 31, so that the electrostatic adsorption assembly 31 can generate an adsorption electric field.

[0048] The first input end 223 and the second output end 224 can be arranged as external ports of the first power supply module 22, facilitating the butt joint of the first power supply module 22 with the electric control device 4 and the second power supply module 32. The second input end 325 and the third output end 326 can be arranged as external ports of the second power supply module 32, facilitating the butt joint of the second power supply module 32 with the electrostatic adsorption assembly 31. The first output end and the input end of the first high-voltage pack 221 can be arranged as internal ports of the first power supply module 22, realizing the electrical connection inside the first power supply module 22.

[0049] In the present scheme, since the electrostatic adsorption module 3 does not separately arrange a high-voltage pack, but shares the first high-voltage pack 221 with the discharge assembly 21, one high-voltage pack is saved, which is conducive to reducing the size of the second power supply module 32, and is conducive to saving installation space and reducing cost.

[0050] When the electrostatic adsorption module 3 is arranged as an optional module, the first input end 223 of the discharge module 2 can be connected to the power output end 41 of the electric control device 4 through the wire body 5 when leaving the factory. When the user purchases the electrostatic adsorption module 3, the electrostatic adsorption module 3 can be installed, and then the second input end of the electrostatic adsorption module 3 is connected to the second output end of the discharge module 2 through the wire body 5.

[0051] In some exemplary embodiments, as shown in Figure 3 The second power supply module 32 is fixed to the cabinet 1. The electrostatic adsorption assembly 31 is detachably connected with the cabinet 1 and the second power supply module 32, such as being detachably connected through snap connection, fastener connection, plug-in connection, etc. In this way, the electrostatic adsorption assembly 31 can be easily detached and cleaned, which is conducive to long-term use of the electrostatic adsorption assembly 31.

[0052] In some exemplary embodiments, the second power supply module 32 is provided with an electrical plug portion 323 (as shown in Figure 4 The electrical plug portion 323 is arranged to be plug-in matched with the electrostatic adsorption assembly 31, so that the electrical connection or disconnection of the electrostatic adsorption assembly 31 with the second power supply module 32 can be realized through plug-in mode, which is simple and convenient to operate and safe and reliable. The micro switch is arranged to be triggered to turn on the circuit of the second power supply module 32 when the electrostatic adsorption assembly 31 is plugged in, which is conducive to improving safety and avoiding safety hazards caused by accidental triggering.

[0053] In some exemplary embodiments, as shown in Figure 4As shown, the electrostatic adsorption assembly 31 includes a frame 311, an electrostatic dust collection sheet 312 arranged on the frame 311, and a grounding plug 313 electrically connected to the electrostatic dust collection sheet 312. The grounding plug 313 can be pluggably connected with the electrical plug portion 323 of the second power supply module 32. The frame 311 can be detachably connected with the cabinet 1 by snap connection, fastener connection, plug-in connection, or other connection manners, so as to facilitate the disassembly and cleaning of the electrostatic adsorption assembly 31.

[0054] In some exemplary embodiments, the power input end is arranged in detachable connection with the power output end 41, such as can be achieved by a pluggable wire body 5, which is simple and convenient to operate, and safe and reliable.

[0055] In some exemplary embodiments, the gap between the discharge assembly 21 and the cabinet 1 is greater than 50 mm.

[0056] Since the cabinet 1 is a sheet metal part with strong adsorption of electric charges, the gap between the discharge assembly 21 and the cabinet 1 is greater than 50 mm, so that the discharge assembly 21 is far away from the cabinet 1, and the charged particles generated by the discharge of the discharge assembly 21 are quickly blown to the indoor space under the blowing of the air flow, and cannot be adsorbed to the sheet metal parts such as the cabinet 1, thereby facilitating the utilization of the charged particles generated by the discharge, and improving the dust removal and sterilization efficiency.

[0057] Of course, the gap between the discharge assembly 21 and the cabinet 1 is not limited to the above range, and can be adjusted as needed.

[0058] In some exemplary embodiments, the discharge assembly 21 includes a first sub-discharge assembly 21 and a second sub-discharge assembly 21, the first sub-discharge assembly 21 is arranged to discharge under the action of negative high-voltage direct current, and the second sub-discharge assembly 21 is arranged to discharge under the action of high-voltage voltage change (such as sinusoidal alternating high-voltage).

[0059] The first sub-discharge assembly 21 can occur corona discharge under the action of negative high-voltage direct current, generate a large amount of electrons, and the electrons are captured by electrophilic oxygen molecules (O2) or water molecules (H2O) in the air to form Be (Biomimetic electronics, biomimetic electronics) 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.

[0060] The second sub-discharge assembly 21 can discharge under the action of high-voltage voltage change to generate a high-energy particle jet zone, which contains a large amount of electrons (e -A variety of sterilization factors such as Be ions, reactive oxygen species (ROS), reactive nitrogen species (RNS), charged particles, free radicals (such as ·OH), etc. can play a good role in killing bacteria, viruses and other microorganisms in the air.

[0061] In addition, the Be ions can generate more high-energy electrons after being fused with high-energy jet particles, and further generate more free radicals and high-energy particles. The combination of the two can expand the range of sterilization and virus removal, and improve the sterilization and virus removal rate and effect.

[0062] The Be ions generated by the first sub-discharge assembly 21 are negative ions, which can stay in the air for a longer time and have strong stability, which is beneficial to improve the dust removal effect. The high-energy jet particles generated by the second sub-discharge assembly 21 are plasma, which has good sterilization effect and is beneficial to improve the sterilization effect. The combination of the two is beneficial to improve the dust removal effect and the sterilization effect, thereby realizing the double optimization of the dust removal effect and the sterilization effect. Tests show that the influenza virus removal rate can reach 99.9% in 1 hour, and the dust mite allergen removal rate can reach about 90% in 2 hours.

[0063] In some exemplary embodiments, as shown in Figure 6 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.

[0064] As shown in Figure 6 The second sub-discharge assembly 21 includes a discharge electrode 212 and a counter electrode 213 arranged opposite to each other, the discharge electrode 212 includes a needle electrode 2121, and the counter electrode 213 is provided with a through hole 2131 corresponding to the needle electrode 2121. In this way, a three-dimensional discharge space can be formed between the discharge electrode 212 and the counter electrode 213, which is beneficial to improve the electric field strength and the density of high-energy particles, thereby improving the sterilization effect.

[0065] The discharge electrode 212 can further include a plate-shaped base, and the number of needle electrodes 2121 can be multiple. The multiple needle electrodes 2121 can be arranged on the plate-shaped base in a spaced manner. The plate-shaped base is electrically connected to the second power supply module 322, so that the multiple needle electrodes 2121 can be electrified together. The counter electrode 213 can be a plate electrode, and the number of through holes 2131 can be equal to and one-to-one corresponding to the number of needle electrodes 2121.

[0066] In some exemplary embodiments, as shown in Figure 5 and Figure 6As shown, the discharge module 2 further includes a mounting seat 23 and a protective cover 24. The first sub-discharge assembly 21 and the second sub-discharge assembly 21 are mounted to the mounting seat 23. The protective cover 24 covers the mounting seat 23 and covers the second sub-discharge assembly 21, and the protective cover 24 is provided with a hollow air passage 241. In this way, the safety performance is improved, and safety accidents caused by accidental touching of the second sub-discharge assembly 21 are avoided. The first sub-discharge assembly 21 can be located outside the protective cover 24. For example, the first sub-discharge assembly 21 can include two ion carbon brush heads 211, and the two ion carbon brush heads 211 are located on the two sides of the protective cover 24, respectively.

[0067] In some exemplary embodiments, as shown in Figure 5 and Figure 6 As shown, the mounting seat 23 includes a seat body 231 and a cover body 232. The seat body 231 can be integrally formed with the box body of the first high-voltage pack 221, and the cover body 232 can be integrally formed with the box cover of the first high-voltage pack 221. The cover body 232 is connected to the seat body 231 in a cover-fit manner, such as through buckling, fasteners, or the like.

The ion carbon brush heads 211 can be fixed to the mounting seat 23 through buckling, fastener connection, or the like. The discharge electrode 212 and the counter electrode 213 can be fixed to the mounting seat 23 through buckling, fastener connection, or the like.

[0068] In the embodiments of the present application, the air conditioner can be an indoor unit of a split-type air conditioner (such as a ducted indoor unit), can be a complete air conditioner including an indoor unit and an outdoor unit, or can be an all-in-one air conditioner.

[0069] As shown in Figure 8 The embodiments of the present application also provide a control method, applied to the air conditioner of any one of the above embodiments, and the control method comprises the following steps:

[0070] Step S202: determining a target purification mode, and the types of the target purification mode include a dust removal mode and a sterilization mode;

[0071] Step S204: controlling the electrostatic dust removal device according to the determined target purification mode.

[0072] The control method provided by the embodiments of the present application can control the electrostatic dust removal device according to the determined target purification mode, provide the user with dust removal, sterilization, and other purification functions, facilitate the satisfaction of different needs of the user, and be beneficial to improving the user experience.

[0073] The method for determining the target purification mode is not limited. It can be determined according to external instructions, such as the user selecting the corresponding purification mode through a remote control, a mobile terminal (such as an APP of a mobile phone, a computer, a bracelet, etc.), a control panel, etc. It can also be automatically determined according to the detection results, such as automatically determining the corresponding purification mode according to the detection results of the indoor air quality.

[0074] In some exemplary embodiments, the electrostatic dust removal device is controlled according to the determined target purification mode, including:

[0075] When the target purification mode is the dust removal mode, the electrostatic dust removal device is controlled to be intermittently turned on;

[0076] When the target purification mode is the sterilization mode, the electrostatic dust removal device is controlled to be continuously operated for a first set time length and then turned off. The first set time length can be, but is not limited to, 2 hours (of course, it can also be less than 2 hours), and the electrostatic dust removal device can be started again after being turned off for 6 hours, that is, it meets the requirement that the cumulative sterilization within 8 hours is not more than 2 hours, as shown in the following table. Figure 9

[0077] Since the electrostatic dust removal device provided in the embodiments of the present application also has a sterilization function, and the current national standard and industry have a restriction requirement on the operation time length of the sterilization function (such as the cumulative sterilization within 8 hours is not more than 2 hours), it is necessary to control the operation time length of the electrostatic dust removal device. In addition, the indoor bacterial population is a short-term limit value and will not increase in a short period after rapid sterilization and removal; and the dust removal function will have new air continuously supplemented due to the influence of factors such as window opening and gaps, so there is a need for long-time dust removal.

[0078] Therefore, when the target purification mode is the dust removal mode, the electrostatic dust removal device can be controlled to be intermittently turned on to meet the requirement of long-time dust removal, but the total cumulative operation time length will not exceed the standard. During the operation of the dust removal mode, sterilization is also performed, so the effect of indirectly realizing long-time operation of the sterilization function is achieved.

[0079] When the target purification mode is the sterilization mode, the electrostatic dust removal device can be controlled to be continuously operated for a first set time length and then stopped, so as to meet the sterilization requirement through rapid sterilization and the operation time length will not exceed the standard. The above control logic can take into account the time length restriction of sterilization and the requirement of long-time dust removal, which is beneficial to maintaining the indoor air clean and continuously purifying the newly entered unclean air, and can overall optimize the actual application effect of sterilization and dust removal.

[0080] In some exemplary embodiments, the electrostatic dust removal device is controlled to be intermittently turned on, including:

[0081] The electrostatic dust removal device is first controlled to be continuously turned on for a second set time length, and then the electrostatic dust removal device is controlled to be intermittently turned on in a cycle of stopping for a third set time length and operating for a fourth set time length.​

[0082] The second set time period is greater than the fourth set time period.

[0083] The electrostatic dust removal device is first controlled to be continuously turned on for the second set time period, so that existing dust mites and other pollutants in the room can be quickly purified. The subsequent periodic intermittent opening only needs to purify the newly entered unclean air, so the single operation time period does not need to be too long.

[0084] In one example, the second set time period can be, but is not limited to, 30 min, the third set time period can be, but is not limited to, 2 min, and the fourth set time period can be, but is not limited to, 1 min. The electrostatic dust removal device is turned off after being accumulated for 120 min.

[0085] In another example, the second set time period can be, but is not limited to, 30 min, the third set time period can be, but is not limited to, 50 min, and the fourth set time period can be, but is not limited to, 10 min. The electrostatic dust removal device is turned off after being accumulated for 120 min in 8 h, as shown in FIG. 8. Figure 10

[0086] In some example embodiments, the air conditioner further includes a fan, and the control method further includes:

[0087] Based on the air conditioner entering the dust removal mode from the off state, the fan is controlled to start running at a set gear;

[0088] Based on the air conditioner entering the dust removal mode from the on state, the fan is controlled to maintain the current state;

[0089] Based on the air conditioner entering the sterilization mode from the off state, the fan is controlled to start running at the highest gear;

[0090] Based on the air conditioner entering the sterilization mode from the on state, the fan is controlled to maintain the current state.

[0091] When entering the dust removal mode or the sterilization mode from the on state, the fan continues to run according to the previous mode (such as the cooling mode or the heating mode) to avoid affecting other functions. During the process, the user can adjust the wind gear or switch to other modes (such as the cooling mode or the heating mode), without affecting the normal operation of the dust removal function. After the time, the electrostatic dust removal device is turned off, and the other functions continue to run.

[0092] When entering the sterilization mode from the off state, the fan is controlled to start running at the highest gear, so as to realize rapid and efficient purification. During the process, the user can adjust the wind gear or switch to other modes (such as the cooling mode or the heating mode), without affecting the normal operation of the dust removal function.

[0093] ​And by the shutdown state into the dust removal mode, the control fan to set the gear start running, facilitate the realization of fast and efficient purification. Because the electrostatic precipitator will be intermittent operation in a long period of time, so the set gear does not need to be too high, such as can be but not limited to the default start gear 60 % or so. In the middle of the user can adjust the air or switch to other modes (such as refrigeration heating), does not affect the normal operation of the dust removal function.

[0094] The embodiment of the present application also provides a control device, comprising a processor and a memory storing a computer program, the processor executes the computer program to realize the steps of the control method in any of the above embodiments, thus having all the beneficial effects described above, which will not be repeated here.

[0097] In summary, the air conditioner, the control method and the control device provided by the embodiment of the present application divide the electrostatic precipitator into two functional modules, namely the discharge module and the electrostatic adsorption module. The discharge module is arranged at the air outlet, so that the generated Be ions and high-energy jet ions will not be sucked into the air duct and then blown out, which is beneficial to prevent the attenuation of ions caused by the adsorption of metal plates, solves the problem of too fast accumulation of static metal, makes the static electricity not reach the degree of static breakdown, thereby solving the problem of static breakdown of the motor, PCB and other components, and indirectly realizing the sterilization function (i.e. long-term sterilization through the dust removal mode) and the effect of long-period operation. The electrostatic dust collection module is designed at the air inlet, which is convenient for capturing dust and disassembling and cleaning. Through the improvement of the control method, the sterilization and dust removal effects can realize more than 99% effect in the whole cycle, and the optimization of the compatibility of the two functions is achieved.
