[0002] Household air conditioners are usually installed in hard-to-clean locations such as inside the ceiling. After a long period of use, the internal equipment, especially the water tray, accumulates a lot of dust and water, which can easily breed bacteria, mold and other microorganisms, leading to bacterial and mold growth in the dust and water layers.

[0003] In related technologies, sterilization is achieved by adding antibacterial agents to the surface of the water receiving pan or by baking the evaporator at high temperatures. However, these technologies are limited to sterilizing components such as the water receiving pan or the evaporator, resulting in sterilization blind spots. Summary of the Invention

[0047] The present application will now be described in further detail with reference to the accompanying drawings and embodiments.

[0048] Currently, most household air conditioners use ducted units installed inside the ceiling, making cleaning the inside of the unit difficult. Especially when there is residual water in the duct tray, it becomes the most serious source of internal contamination compared to other parts of the unit, such as split or floor-standing units. After prolonged use, various bacteria, molds, and other microorganisms can proliferate in the water remaining in and on the surface of the duct tray. These microorganisms can even form jelly-like impurities that clog the water pump used to drain the water. If the water in the duct tray cannot be drained for an extended period, it will produce an unpleasant odor when the air conditioner is restarted, polluting indoor air and affecting the user's health.

[0049] In related technologies, air conditioners are equipped with a self-cleaning function. This function involves controlling the evaporator to operate at a temperature above 56 degrees Celsius, using the generated high temperature to bake and sterilize the interior of the unit. However, this high-temperature sterilization method using the evaporator can only kill bacteria on the surface of the evaporator itself. It cannot effectively sterilize other equipment in the air conditioning duct unit, such as the drain pan, water pump, and other drainage system equipment, as well as areas in the air duct system such as the impeller and volute that are prone to dust and water accumulation. As a result, when the air conditioner is restarted, the odor produced by microorganisms is blown into the room, polluting the indoor environment.

[0050] Furthermore, in related technologies, duct air conditioners with built-in sterilization functions add antibacterial agents to the water tray and mold it as a single piece, and then install the antibacterial water tray inside the duct air conditioner. However, in these technologies, the sterilization of microorganisms is limited to the water tray itself. Once a large amount of dust and water accumulates in the water tray, the microbial growth area detaches from the surface of the water tray and grows in the dust layer or water. This means that the antibacterial water tray cannot solve the bacterial and mold growth in the dust and water layers, resulting in sterilization dead zones. As a result, effective sterilization cannot be achieved, and when the air conditioner is restarted, there will still be odors blowing out, polluting the indoor air.

[0051] Based on this, this application provides a method for controlling an air conditioner, referring to... Figure 1 As shown, the method includes the following steps:

[0052] Step 101: Obtain the first reference information.

[0053] The first reference information indicates the operating status of the air conditioner.

[0054] Understandably, the executing entity in this embodiment is the aforementioned air conditioner, which has functions such as data processing, data communication, and program execution. Typically, the operation of each component in an air conditioner can be driven by a core controller; therefore, the executing entity in this embodiment can also be the core controller within the aforementioned air conditioner, which can be a processor.

[0055] In this embodiment, the first reference information can be generated directly by the air conditioner or by an electronic device associated with the air conditioner. Electronic devices include, but are not limited to, smart home devices, smart robots, mobile phones, tablets, wearable devices, laptops, super mobile personal computers, netbooks, personal digital assistants (PDAs), etc., and may also include servers and service response systems based on terminal artificial intelligence. This embodiment does not impose any restrictions on the specific type of electronic device. The aforementioned electronic device can serve as a linkage accessory for the ducted air conditioner, possessing the function of measuring air quality parameters (including temperature and humidity data, carbon dioxide concentration data). Smart home devices include, but are not limited to, air quality monitoring devices.

[0056] For example, the operating states of an air conditioner include, but are not limited to, being off, on, in heating mode, in cooling mode, in dehumidification mode, and in ventilation mode. It should be understood that in heating mode, cooling mode, and dehumidification mode, the evaporator of the air conditioner is in the operating state; in the off state and ventilation mode, the evaporator of the air conditioner is in the off state.

[0057] Step 102: Based on the first reference information, control the air conditioner to enter the first mode.

[0058] The first mode includes: controlling the air conditioner's sterilization module to sterilize the air duct path.

[0059] In this embodiment, the air duct path includes a path formed by connecting the return air vent and the air outlet provided on the main casing of the air conditioner. The air duct path may also include at least one of the air duct path of the air conditioner's duct unit and the air duct path of the room space where the air conditioner is located. The air duct path is provided with air duct path components, which, exemplarily, include but are not limited to fan assemblies, main casing panels, etc.

[0060] In this embodiment of the application, the sterilization module refers to a device or component capable of generating air conditioning sterilization equipment.

[0061] For example, the sterilization module can sterilize by releasing sterilizing ions or by other means, depending on the actual situation. This application does not limit this.

[0062] In this embodiment of the application, the air conditioner sterilization module is controlled to sterilize the air duct path according to the obtained air conditioner operating status, including sterilizing the air duct path components on the air duct path.

[0063] In this embodiment, controlling the air conditioner to enter the first mode can be in response to receiving a first related instruction or control information. The instruction or control information can be generated directly by the air conditioner or by an electronic device associated with the air conditioner. Electronic devices include, but are not limited to, smart home devices, smart robots, mobile phones, tablets, wearable devices, laptops, super mobile personal computers, netbooks, personal digital assistants (PDAs), etc., and may also include servers and service response systems based on terminal artificial intelligence. This embodiment does not impose any restrictions on the specific type of electronic device. The aforementioned electronic device can serve as a linkage accessory for ducted air conditioners, having the function of measuring air quality parameters (including temperature and humidity data, carbon dioxide concentration data, etc.). Smart home devices include, but are not limited to, air quality monitoring devices.

[0064] For example, the first relevant instruction or control information for controlling the air conditioner to enter the first mode can be one or more of the following: a user-issued instruction to enter the sterilization mode, a heating start signal for the air conditioner, a cooling start signal for the air conditioner, and air quality. The specific settings are determined according to actual needs, and this application does not limit them.

[0065] In a feasible scenario, upon receiving a sterilization control command from the user, the air conditioning sterilization module automatically controls the air duct sterilization module to sterilize the air duct path of the duct unit and the air duct path of the room where the air conditioner is located, as well as the air duct path components on the air duct path, based on the air conditioner's operating status.

[0066] Step 103: Confirm that the air conditioner has exited the first mode and control it to enter the second mode.

[0067] The second mode includes: controlling the sterilization module of the air conditioner to sterilize the water flow path.

[0068] In this embodiment of the application, the water flow path includes the path through which condensate drips from the evaporator to the water storage component. Water flow path components are provided on the water flow path. For example, the water flow path components include, but are not limited to, the evaporator, the water storage component, and the water pump.

[0069] It should be understood that the water flow path components may also include the evaporator circulation pipes in the air conditioner, as well as various components on the pipes.

[0070] Accordingly, the exit conditions for controlling the air conditioner to exit the first mode include one or more of the following: receiving an exit command for heating mode, cooling mode or dehumidification mode, reaching the running time of the first mode, or receiving an start command for the second mode.

[0071] In this embodiment, after determining that the air conditioner has exited the first mode, it is automatically controlled to enter the second mode. Understandably, based on the obtained operating status of the air conditioner, after controlling the air conditioner sterilization module to exit sterilizing the air duct path, it continues to control the air conditioner sterilization module to sterilize the water flow path, including sterilizing the water flow path components.

[0072] This application provides an air conditioner control method, comprising: acquiring first reference information, the first reference information indicating the operating status of the air conditioner; controlling the air conditioner to enter a first mode according to the first reference information, the first mode including: controlling the air conditioner's sterilization module to sterilize the air duct path; determining that the air conditioner exits the first mode and controlling the air conditioner to enter a second mode, the second mode including: controlling the air conditioner's sterilization module to sterilize the water flow path. This application sterilizes the surfaces of all components in the internal water flow path and air duct path of the air conditioner, and sterilizes the room space where the air duct path is located, achieving dual effective sterilization of both surfaces and space. This solves the problem that related technologies are limited to components such as water trays or evaporators for microbial sterilization, resulting in sterilization dead zones.

[0073] In some embodiments of this application, step 102, controlling the air conditioner to enter a first mode based on the first reference information, includes:

[0074] If the first reference information indicates that the air conditioner is not in cooling or heating mode, then obtain the second reference information, which indicates the air quality.

[0075] According to the second reference information, the air conditioner is controlled to enter the first mode. The first mode further includes: controlling the sterilization module to sterilize the air duct path components according to the control parameters associated with the second reference information.

[0076] It should be understood that the air conditioner is not in cooling or heating mode, including when the air conditioner is off or in ventilation mode, in which case the evaporator is closed.

[0077] For example, air quality can be indicated by air quality levels, which include, but are not limited to, good, moderate, and poor air quality.

[0078] For example, air quality can also be indicated by air quality parameters, including but not limited to smoke concentration, total suspended particulate matter, inhalable particulate matter (PM10), fine particulate matter (PM2.5), nitrogen dioxide, sulfur dioxide, carbon monoxide, ozone, and volatile organic compounds. A specific parameter can be selected for air quality detection and acquisition; this application does not impose any specific limitations on this.

[0079] In this embodiment of the application, when the first reference information indicates that the air conditioner is not in cooling or heating mode, the air conditioner is automatically controlled to enter the first mode according to the air quality indicated by the second reference information.

[0080] In this embodiment, the control parameters associated with the second reference information include the second operating duration of the sterilization module and the second operating voltage of the sterilization module. When the acquired first reference information indicates that the air conditioner's operating state is not cooling or heating, it means that the air conditioner's evaporator is not running. Furthermore, when the air conditioner is in a shutdown state, the air conditioner's fan assembly is also off. In response to receiving a sterilization control command from the user, the sterilization module is controlled to operate for the second operating duration according to the second operating voltage, based on the current air quality, to sterilize the components along the air duct path.

[0081] In this embodiment, the control parameters associated with the second reference information also include the start-up duration of the fan assembly and the operating voltage of the fan assembly. When the acquired first reference information indicates that the air conditioner's operating state is not cooling or heating, and when the air conditioner's operating state is off, it indicates that the air conditioner's evaporator is not running and the air conditioner's fan assembly is also off. In response to receiving the user's sterilization control command, the sterilization module is started according to the current air quality. The sterilization module is controlled to start for a second operating duration according to the second operating voltage to sterilize the air duct path components. At the same time, the fan assembly is started and rotated according to the fan assembly's start-up duration and operating voltage to drive the air in the air duct path to flow rapidly, thereby assisting the sterilization module in sterilizing the air duct path of the ducted air conditioner and the air duct path of the room where the air conditioner is located, as well as the air duct path components on the air duct path. Understandably, when the first reference information indicates that the air conditioner is not in cooling or heating mode, and when the air conditioner is in ventilation mode, the evaporator is not running, but the fan assembly is on. Based on the user's sterilization needs and the current air quality, the sterilization module can be activated.

[0082] In this embodiment, when the air conditioner is not in cooling or heating mode, the sterilization module and fan assembly are activated based on air quality and run for a period of time to sterilize the components in the air duct path. Thus, by activating the fan assembly, air circulation in the air duct path is accelerated, rapidly dispersing air carrying sterilizing ions to the duct unit and room space, as well as the surfaces of various components within the air duct path, achieving effective sterilization of the air in the duct unit and room space.

[0083] It should be noted that sterilizing the surface of a component can be called surface sterilization or surface disinfection; sterilizing the air can be called air sterilization or air disinfection.

[0084] Furthermore, in some embodiments of this application, the second mode further includes: controlling the corresponding components to perform one or more of the following events: starting the evaporator drying process, stopping the fan assembly, and closing and sealing the panel, and then controlling the sterilization module to sterilize the water flow path components.

[0085] In this embodiment of the application, when it is determined to exit the first mode, it indicates that the sterilization process of the air duct path of the air conditioner is ended, and the air conditioner is controlled to enter the second mode, that is, to enter the sterilization process of the water flow path of the air conditioner.

[0086] Furthermore, in some embodiments of this application, controlling the sterilization module to sterilize water flow path components includes:

[0087] The sterilization control module sterilizes the water flow path components according to the control parameters associated with the first reference information.

[0088] In this embodiment, the control parameters associated with the first reference information include the first operating time of the sterilization module and the first operating voltage of the sterilization module.

[0089] It should be noted that the first operating time and the aforementioned second operating time can be the same or different, and the first operating voltage and the aforementioned second operating time can be the same or different, depending on the first reference information and the second reference information.

[0090] In this embodiment, the operating status of the air conditioner indicated by the first reference information is obtained. Based on the current operating status of the air conditioner, the first operating duration of the sterilization module associated with the first reference information and the first operating voltage of the sterilization module are obtained. After the evaporator drying process is started, the fan assembly stops running, and the panel is closed and sealed, the sterilization module is controlled to start for a first duration according to the first operating voltage to sterilize the water flow path components.

[0091] In one feasible embodiment of this application, when the air conditioner is operating in cooling mode or dehumidification mode, condensation forms on the surface of the internal components. When the end of cooling mode or dehumidification mode is detected, or when an exit command for cooling mode or dehumidification mode is received, the air conditioner is controlled to exit the first mode and enter the second mode. Since condensation forms on the surface of the internal components during the first mode operation, in the second mode, the evaporator is activated to dry the interior of the air conditioner, effectively reducing water accumulation. Simultaneously, the fan assembly is stopped, the control panel is sealed, and the sterilization module is activated for a first operating time according to a first operating voltage to sterilize the water flow path components of the air conditioner, including deep sterilization of residual condensation in the water storage components of the water flow path components.

[0092] Accordingly, in some embodiments of this application, the second mode further includes: controlling the corresponding component to perform one or more of the following events: after the fan assembly stops running and the panel is closed and sealed, controlling the sterilization module to sterilize the water flow path component.

[0093] In this embodiment, when the air conditioner is in heating mode, no condensation forms on the surface of the internal components. When the end of heating mode is detected, or a command to exit heating mode is received, the air conditioner exits the first mode and enters the second mode. Since no condensation forms on the surface of the internal components during the first mode operation, in the second mode, the evaporator is not started, the fan assembly is stopped, the control panel is sealed, and the sterilization module is started at a preset voltage for a period of time to sterilize the water flow path components of the air conditioner.

[0094] In this embodiment, because the panel is closed and sealed, the bactericidal ions released by the sterilization module diffuse along the water flow path components and air duct path components inside the air conditioner's main casing, diffusing and depositing on the surfaces of all components along the path, thus achieving surface sterilization of the water flow path components and air duct path components. Furthermore, because the control fan assembly stops operating, the concentration of bactericidal ions from the sterilization module in the air remains high, allowing the high-energy, high-concentration bactericidal ions to penetrate deeply into the accumulated water inside the air conditioner, achieving effective sterilization of the water in the water flow circuit.

[0095] Furthermore, in some embodiments of this application, the first reference information indicates that the air conditioner is in cooling operation, and the second mode further includes: controlling the air conditioner's water pump to drain the air conditioner's water storage component, and after the drainage is completed, controlling the sterilization module to sterilize the water flow path components according to the control parameters associated with the first reference information.

[0096] In one feasible embodiment of this application, when the air conditioner is operating in cooling mode, condensation forms on the surface of the internal components. When the end of the cooling mode is detected, or a command to exit the cooling mode is received, the air conditioner is controlled to exit the first mode and enter the second mode. Since condensation forms on the surface of the internal components during the first mode operation, in the second mode, the air conditioner's water pump can also be controlled to drain the water storage component, effectively reducing water accumulation inside the air conditioner. Simultaneously, the fan assembly is stopped, the control panel is sealed, and the sterilization module is started at a preset voltage for a certain period (e.g., a first operating voltage for a first operating period) to sterilize the water flow path components, including deep sterilization of residual condensation in the water storage component. Understandably, while the air conditioner's water pump is draining the water storage component, the evaporator can also be started to dry the interior of the air conditioner, further improving the drainage efficiency of the internal water.

[0097] Accordingly, embodiments of this application also provide an air conditioner, referring to... Figure 2 As shown, the air conditioner 20 includes:

[0098] The main housing 201 is provided with a return air inlet 202 and an air outlet 203, which are connected to form an air duct path 204.

[0099] Evaporator 205 is installed inside the main casing 201;

[0100] The water storage component 206 is located below the evaporator 205. The water storage component 206 can receive and store the condensate on the evaporator 205. The path of the condensate from the evaporator 205 to the water storage component 206 forms a water flow path 207.

[0101] The sterilization module 208 is located at the intersection of the air duct path 204 and the water flow path 207.

[0102] In this embodiment of the application, the sterilization module refers to a device or component capable of generating air conditioning sterilization equipment.

[0103] For example, the sterilization module can sterilize by releasing sterilizing ions or by other means, depending on the actual situation. This application does not limit this.

[0104] In the embodiments of this application, reference is made to Figure 3 As shown, the intersection of the air duct path 204 and the water flow path 207 can be at the center or one side of the air duct path 204 inside the air conditioner main housing 201. When the sterilization module 208 is activated, the sterilization ions released by the sterilization module 208 can diffuse from inside the air conditioner main housing 201 to the outside of the air conditioner main housing 201, including diffusion along the air duct path 204 towards the air outlet 203 and diffusion along the air duct path 204 towards the return air outlet 202.

[0105] In the embodiments of this application, reference is made to Figure 2 As shown, the sterilization module 208 is positioned above the water storage component 206, in the empty space between the components of the water flow path 207 and the components of the air duct path 204.

[0106] This application embodiment sets up a sterilization module at the intersection of the air duct path and the water flow path, where dust, mold, and fungi are prone to accumulate. When the sterilization module is activated, the sterilization ions released by the sterilization module can sterilize the water flow path and the water storage components in the water flow path. At the same time, the sterilization ions quickly diffuse to the surface of all components in the air duct path, achieving dual sterilization of the air duct path components and the water flow path components.

[0107] In some embodiments of this application, see [link to relevant documentation]. Figure 4 As shown, the sterilization module 208 includes:

[0108] Positive and negative electrode components 2081 are used to generate bactericidal ions;

[0109] High voltage transformer assembly 2082 is connected to positive and negative electrode components 2081 and is used to provide high voltage power to positive and negative electrode components 2081.

[0110] Reference Figure 5As shown, the high-voltage transformer assembly 2082 provides a negative high voltage, generating an electric field between the corona electrode and the collector of the positive and negative electrode components 2081. Seed electrons gain energy from the electric field, collide with neutral particles, and ionize them to produce free electrons and positive ions. Negative ions are then generated through an adsorption process, thus producing a bactericidal ion cluster (containing positive ions, negative ions, and neutral particles). In this way, bactericidal ions can be generated by utilizing the ionization and adsorption processes of corona discharge.

[0111] In some embodiments of this application, see [link to relevant documentation]. Figure 4 As shown, the sterilization module 208 also includes:

[0112] The diffuser cover 2083 has an opening 2084 on it for the sterilization module 208. When the sterilization module 208 is activated, sterilization ions are released from the opening 2084 to sterilize the air duct path 204 and / or the water flow path 207.

[0113] In the embodiments of this application, reference is made to Figure 2 and Figure 4 As shown, based on the principle of corona discharge, the positive and negative electrode components 2081 are controlled to generate sterilizable negative ions between the electrodes, and the sterilizable negative ions are released through the opening 2084 provided on the diffusion cover plate 2083. The released sterilizable ions can diffuse to the air duct path 204 and / or water flow path 207, and cover the surface of all components of the air duct path 204 and / or water flow path 207, as well as the water in the water storage component 206, so as to achieve dual sterilization of the air duct path 204 and / or water flow path 207.

[0114] In the embodiments of this application, reference is made to Figure 5As shown, the process of generating a pulse storm of bactericidal ions based on the principle of corona discharge includes: Ionization process: Seed electrons gain energy from the electric field and collide with neutral particles, causing them to ionize and produce free electrons and positive ions. The newly generated electrons, after gaining sufficient energy, will ionize neutral molecules again, producing more electrons and positive ions, forming an electron avalanche; Adsorption process: Free electrons generated by ionization are adsorbed by negatively charged gases to form negative ions. The negatively charged gases in the air are mainly oxygen, so electrons mainly recombine with oxygen molecules to form negative oxygen ions; Recombination process: The recombination process mainly occurs in the ionization region, where positive ions recombine with electrons or negative ions to form negative oxygen ions. The rate constant of the recombination reaction is related to the electron energy; the higher the energy, the more difficult it is to recombine. Secondary electron emission: Corona discharge is a self-sustaining discharge that does not require an external ionization source, so secondary electron emission is inevitable. It is generally believed that secondary electron emission in corona discharge is mainly generated by photoionization and bombardment of the cathode surface by positive ions, and field emission is also possible. Migration process: The directional movement of charged particles under the inter-electrode electric field. Diffusion process: The free diffusion process of charged particles. Space charge distribution: The changing space charge field generated by the movement of charged particles within the discharge region affects the distribution of the entire inter-electrode electric field.

[0115] For example, the blowing distance of the ion wind directly blown by the pulse storm can be 0.5 to 1 m.

[0116] In some embodiments of this application, reference is made to Figure 6 As shown, the water storage area 2061 of the water storage component 206 is within the area covered by the bactericidal ions released by the diffusion cover plate 2083.

[0117] The water storage component can be the water tray of an air conditioner, and the water storage area 2061 can also be called the water accumulation area of ​​the water tray.

[0118] In the embodiments of this application, reference is made to Figure 2 and Figure 6 As shown, the sterilization module 208 is positioned directly above the water storage area 2061 of the water storage component 206, further... Figure 4 As shown, the diffusion cover plate 2083 of the sterilization module 208 is provided with an opening 2084, which faces the water storage area 2061 of the water storage component 206. This ensures that when the sterilization module 208 is activated to release sterilizing ions, the water storage area 2061 can be completely covered by the sterilizing ions released by the diffusion cover plate 2083, thereby improving the sterilization effectiveness.

[0119] In some embodiments of this application, see [link to relevant documentation]. Figure 2 As shown, air conditioner 20 also includes:

[0120] The fan assembly 209, which is installed in the air duct path 204, introduces outdoor air into the air duct path 204 from the return air inlet 202 and then discharges it into the room from the air outlet 203.

[0121] The sterilization module 208 is located at the intersection of the air duct path 204 and the water flow path 207, and is situated on the outer edge of any fan assembly 209; or,

[0122] The sterilization module 208 is located at the intersection of the air duct path 204 and the water flow path 207, and at the center of two adjacent fan components 209.

[0123] In the embodiments of this application, see Figure 2 As shown, when the air conditioner is equipped with multiple parallel fan assemblies 209, since there is sufficient installation space between the multiple parallel fan assemblies, the sterilization module 208 can be set at the outer edge of any fan assembly 209 or at the corresponding center position between two adjacent fan assemblies 209, so as to avoid the installation of the sterilization module 208 conflicting with the installation of other components.

[0124] It should be understood that the sterilization module is set at the intersection of the air duct path and the water flow path. Based on this, the sterilization module is set directly above the water storage area of ​​the water storage component and in a reasonable position between the evaporator and the impeller assembly.

[0125] In the embodiments of this application, reference is made to Figure 2 As shown, the air conditioner is also equipped with a fan assembly 209, which is used to introduce outdoor air from the return air inlet 202 into the air duct path 204 and then exhaust it into the room from the air outlet 203. When the sterilization module 208 is turned on, the fan assembly accelerates the air circulation speed in the air duct path 204, so that the sterilization ions generated by the sterilization module 208 can quickly diffuse through the air duct path 204 to the inside of the air conditioner and the room where the air conditioner is installed, thereby achieving effective sterilization of the air inside the room and the air duct.

[0126] In some embodiments of this application, reference is made to Figure 6 As shown, air conditioner 200 also includes:

[0127] Water pump 210 is used to drain water from water storage component 206.

[0128] In the embodiments of this application, reference is made to Figure 6 As shown, the water pump 210 is used to drain the water storage area 2061 of the water storage component 206 to effectively reduce water accumulation inside the air conditioner.

[0129] The following section provides a more detailed description of this application with reference to application examples.

[0130] In a real-world scenario, referencing Figure 7As shown, a control method for an air conditioner is proposed, which can be applied to the aforementioned air conditioner. The specific details are as follows:

[0131] Step 701: Obtain the air conditioner's operating status.

[0132] Step 702: Determine whether the air conditioner is in the off state. If yes, proceed to step 703: Control the air conditioner to perform air sterilization independently in the off state. Otherwise, proceed to step 711.

[0133] Step 703: Obtain air quality.

[0134] Step 704: Determine the air quality level. When the air quality level is good, it indicates that the air quality is relatively good, and short-term sterilization can achieve a good sterilization effect. Proceed to step 705. When the air quality level is medium, it indicates that the air quality is average, and short-term sterilization can achieve a good sterilization effect. Proceed to step 706. When the air quality level is poor, it indicates that the air quality is poor, and longer-term sterilization is required to achieve a good sterilization effect. Proceed to step 707.

[0135] Step 705: Turn on the sterilization module and control the main fan to start short-term air sterilization.

[0136] Step 706: Turn on the sterilization module and control the air sterilization during the start-up of the main fan.

[0137] Step 707: Turn on the sterilization module and control the main fan to start long-term air sterilization.

[0138] In this embodiment, the sterilization module is activated to generate sterilizing ion clusters, and the main fan's air supply mode is activated simultaneously to promote the airflow speed in the air duct where the main fan is located, generating circulating air volume. Through the circulating air volume in the main air duct, the sterilizing ions are diffused through the air outlet of the air conditioner to the entire space of the room where the air conditioner is located, thereby achieving sterilization of the air in the room.

[0139] It should be understood that, since there are relatively few bacterial carriers in the air, controlling the operation of the main fan to drive airflow is necessary to dilute the high concentration of ions generated by the sterilization module, so that the air conditioner's outlet can release a certain amount of relatively low concentration of ions to sterilize the air in a large space.

[0140] Step 708: After the air sterilization time is reached, enter the water meter-free sterilization mode. This indicates that there is no water accumulation when the air conditioner is turned off, and there is no need to sterilize the water. Proceed to step 709.

[0141] Step 709: Control the main fan to stop, close and seal the panel, and run the sterilization module at a constant voltage V1 for a duration of t1.

[0142] Step 710: Sterilization complete.

[0143] Step 711: Control the air conditioner to start operation. When the user turns on the heating mode, control the air conditioner to operate in heating mode and proceed to step 712; when the user turns on the cooling or dehumidification mode, control the air conditioner to operate in cooling or dehumidification mode and proceed to step 714.

[0144] Step 712: The evaporator is in heating mode, and the sterilization module is turned on to sterilize the air.

[0145] Step 713: Exit heating mode. Since there is very little condensation on the surfaces of the components of the indoor unit in heating mode, proceed to step 708 to enter the water meter kill mode.

[0146] Step 714: The evaporator is in cooling or dehumidification mode, and the sterilization module is turned on to sterilize the air.

[0147] Step 715: Exit cooling or dehumidification mode. Because a significant amount of condensation forms on the surfaces of various components of the air conditioner's indoor unit during cooling or dehumidification mode, proceed to step 716 to enter the water meter kill mode.

[0148] Step 716: Enter the water meter killing mode.

[0149] Step 717: Start the evaporator for drying, stop the main fan, and close and seal the control panel. This is used to further sterilize the remaining residual water, proceeding to step 721.

[0150] After steps 718 and 716, determine whether the air conditioner has a water pump. If yes, proceed to step 719; otherwise, proceed to step 720.

[0151] Step 719: Start the water pump for periodic drainage. Because a significant amount of condensate forms on the surfaces of various components of the air conditioner's indoor unit during cooling or dehumidification mode, control the water pump to drain the condensate. Further sterilize the remaining residual water, proceeding to step 721.

[0152] Step 720: Activate natural cycle drainage. During cooling or dehumidification mode, a significant amount of condensation forms on the surfaces of various components of the air conditioner's indoor unit. Utilize the natural drainage function of the air conditioner to drain this condensation. Further sterilize any remaining residual water, proceeding to step 721.

[0153] Step 721: Control the sterilization module to run at a constant voltage V2 (V2≥V1) for a duration of t2 (t2>t1). After sterilization, proceed to step 710. Due to the large number of bacteria, molds, and other microorganisms present in the residual water, compared to the sterilization mode without a water meter, the sterilization mode with a water meter, based on the evaporator drying process, further employs a higher voltage and a longer sterilization duration to deeply sterilize the residual water.

[0154] In this embodiment of the application, when the air conditioner is controlled to enter the surface sterilization mode, the main fan is not operated, and only the sterilization module is turned on to sterilize the components inside the air conditioner. Therefore, it can also be called the static sterilization mode. The static sterilization mode includes the waterless surface sterilization mode and the water-carrying mode.

[0155] In this embodiment, only the sterilization module is activated to generate a cluster of sterilizing ions, which are released outwards along the opening of the sterilization module and directly cover the entire water accumulation area of ​​the drip tray. Because the main fan is not operated, the concentration and energy of the sterilizing ions released from the opening of the sterilization module are high. These high-energy, high-concentration ions can penetrate deeply into the residual water in the water accumulation area, achieving effective sterilization of the water area. Simultaneously, the sterilizing ions can diffuse along the air duct radially towards the evaporator side and along the fan assembly towards the return air vent side within the entire duct space. The diffused sterilizing ions will deposit on the surfaces of various components in the duct unit's air circuit, thereby achieving highly efficient internal sterilization of the air conditioner.

[0156] It should be understood that due to the large amount of microorganisms and dust that grow in the water collection area of ​​the water tray, as well as on various components of the air conditioning duct and water flow path, a high concentration of bactericidal ions is required. Therefore, controlling the main fan to stop and avoiding rapid airflow allows the high concentration of bactericidal ions released by the bactericidal module to diffuse into the air conditioning unit, thereby improving the bactericidal effect.

[0157] In a practical scenario, based on the method and device of this application embodiment, sterilization detection is performed on the accumulated water in the air conditioner's drip tray, referring to... Figure 8 As shown, the results indicate that the sterilization rate is highest at positions 1 and 2, which are closer to the sterilization module, reaching 98.7%. In contrast, the sterilization rate at position 6, which is farther from the sterilization module, is lower than that at positions 1 and 2. However, the average sterilization rate at different positions can reach 92.2%, which reflects the overall high level of sterilization effect of the sterilization module at different positions connected to the water tray.

[0158] This application embodiment adds a sterilization module at the intersection of components or parts in the air conditioning duct unit, where dust, mold, and fungi easily accumulate (corresponding to the aforementioned air duct path) and water circuit (corresponding to the aforementioned water flow path). This maximizes the positional advantage of the sterilization module. The sterilization module generates sterilization ion clusters based on the principle of corona discharge. The pulse storm formed by the sterilization ion clusters blows directly towards the water receiving area below the evaporator component in the water circuit. At the same time, it can quickly diffuse to the surfaces of all objects in the air circuit (corresponding to the surfaces of the aforementioned components) and release low-concentration sterilization ions into the room space for air sterilization. This provides dual sterilization of the air conditioning unit and the room space, solving the problem that related technologies are limited to components such as the water receiving tray or evaporator for sterilization, resulting in sterilization dead zones.
