Technical Field

[0001] This invention relates to the field of air conditioner technology, and in particular to a control method, device, air conditioner, and storage medium for an air conditioner. Background Technology

[0002] With the development of technology, more and more air conditioners are equipped with nano water ion modules to sterilize the space where the indoor unit is located. The nano water ion module condenses water in the air into water droplets, and then ionizes and decomposes the water droplets into water molecules that encapsulate active substances, thereby achieving the sterilization function. However, the air humidity in the space is not constant, which makes the nano water ions generated by the nano water ion module unstable, thus failing to achieve a stable sterilization effect.

[0003] The above content is only used to help understand the technical solution of the present invention and does not represent an admission that the above content is prior art. Summary of the Invention

[0049] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0050] It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the invention.

[0051] Reference Figure 1 , Figure 1 This is a schematic diagram of the air conditioner structure in the hardware operating environment involved in the embodiments of the present invention.

[0052] like Figure 1 As shown, the air conditioner may include: a processor 1001, such as a central processing unit (CPU), a communication bus 1002, a user interface 1003, a network interface 1004, and a memory 1005. The communication bus 1002 is used to enable communication between these components. The user interface 1003 may include a display screen and an input unit such as a keyboard; optionally, the user interface 1003 may also include a standard wired interface or a wireless interface. The network interface 1004 may optionally include a standard wired interface or a wireless interface (such as a Wireless-Fidelity (Wi-Fi) interface). The memory 1005 may be high-speed random access memory (RAM) or stable non-volatile memory (NVM), such as a disk storage device. Optionally, the memory 1005 may also be a storage device independent of the aforementioned processor 1001.

[0053] Those skilled in the art will understand that Figure 1 The structure shown does not constitute a limitation on the air conditioner and may include more or fewer components than shown, or combine certain components, or have different component arrangements.

[0054] like Figure 1 As shown, the memory 1005, which serves as a storage medium, may include an operating system, a network communication module, a user interface module, and a control program for an air conditioner.

[0055] exist Figure 1 In the air conditioner shown, the network interface 1004 is mainly used for data communication with the network server; the user interface 1003 is mainly used for data interaction with the user; the processor 1001 and the memory 1005 in the air conditioner of the present invention can be set in the air conditioner, and the air conditioner calls the control program of the air conditioner stored in the memory 1005 through the processor 1001 and executes the control method of the air conditioner provided in the embodiment of the present invention.

[0056] This invention provides a control method for an air conditioner, wherein the indoor unit of the air conditioner is equipped with a nano-water ion module for air sterilization, as described above. Figure 2 , Figure 2This is a flowchart illustrating the first embodiment of the control method for the air conditioner of the present invention.

[0057] In this embodiment, the control method for the air conditioner includes the following steps:

[0058] Step S1: When the sterilization mode is activated, obtain the air humidity in the space where the indoor unit is located.

[0059] It should be noted that the executing entity of this embodiment can be a control device of an air conditioner with data processing, network communication and program running functions, or other devices with the same or similar functions. The following uses the control device of an air conditioner (hereinafter referred to as the control device) as an example to illustrate this embodiment and the following embodiments.

[0060] Understandably, referring to Figure 3 , Figure 3 This is a schematic diagram of the nano-water ion module. The nano-water ion module includes a semiconductor heat sink A, a semiconductor cooling electrode B, a condensate enrichment head C, and a negative high-voltage plate D. The semiconductor cooling electrode B is grounded, and the negative high-voltage plate D is connected to a high-voltage power supply E. When the semiconductor is energized, the semiconductor heat sink A dissipates heat, and the semiconductor cooling electrode B cools. Moisture in the air near the condensate enrichment head condenses to form water droplets. The semiconductor cooling electrode B is grounded and forms a high-voltage electric field with the negative high-voltage plate D. Under the action of the electric field force, water molecules break down and separate to form free radicals and nano-water ions. If the air conditioner has a humidification function, the humidification water tank F can be connected to the condensate enrichment head C through a pipe, and the water in the humidification water tank can be directly transported to the condensate enrichment head C for ionization.

[0061] It should be understood that the sterilization mode can be a mode that generates nano-water ions to sterilize the space by controlling the operation of the nano-water ion module. The sterilization mode can be turned on by the user during the operation of the air conditioner, or it can be turned on automatically when the sterilization time set by the user is reached, or it can be turned on by other means. This embodiment does not impose any restrictions here. In this embodiment, the humidity of the air in the space can be obtained by a humidity sensor installed in the air conditioner.

[0062] Step S2: Determine the control parameters of the nano water ion module based on the air humidity.

[0063] In this embodiment, the control parameters can be parameters that control the operation of the nano-water ion module set in the air conditioner. The control parameters include parameters such as the power-on time and power-on voltage of the nano-water ion module. The mapping relationship between air humidity and control parameters can be preset, and the control parameters of the nano-water ion module are determined according to the air humidity obtained by the humidity sensor and the preset mapping relationship.

[0064] Step S3: Control the nano water ion module using the control parameters.

[0065] In a specific implementation, assuming that during the operation of the air conditioner, the user sends a command to activate the sterilization mode via the remote control, the control device collects the air humidity of the indoor space where the indoor unit is located through the humidity sensor when the air conditioner activates the sterilization mode according to the command, determines the control parameters of the nano water ion module based on the air humidity and the preset mapping relationship, and controls the nano water ion module to perform space sterilization based on the control parameters.

[0066] Furthermore, in order to enable the nano-water ion module to stably generate nano-water ions and improve the sterilization effect of the air conditioner, step S2 includes:

[0067] Step S21: Compare the air humidity with the preset air humidity range.

[0068] It is understood that the preset air humidity range can be a pre-set air humidity range; the preset air humidity range can be set in the following ways: (1) the optimal humidity range for the nano water ion module to generate nano water ions is preset as the air humidity range; (2) the preset air humidity range is determined according to the humidity range of the air humidity value in the sales area or region of the air conditioner. The humidity range can also be set in other ways, which are not limited in this embodiment.

[0069] Step S22: Determine the control parameters of the nano water ion module based on the comparison results of air humidity.

[0070] It is understandable that the comparison results include air humidity within the preset air humidity range, air humidity greater than the upper limit of the preset air humidity range, and air humidity less than the lower limit of the preset air humidity range.

[0071] In this embodiment, a first control parameter can be preset to indicate that the air humidity is within a preset air humidity range; a second control parameter can be preset to indicate that the air humidity is greater than the upper limit of the preset air humidity range; and a third control parameter can be preset to indicate that the air humidity is less than the lower limit of the preset air humidity range. When controlling the nano-water ion module, the first, second, or third control parameter is called based on the comparison result between the air humidity and the preset air humidity range. Alternatively, a baseline control parameter can be preset to indicate that the air humidity is within the preset air humidity range, and a preset threshold can be set. The system uses a high coefficient and a preset reduction coefficient. The preset increase coefficient is a number greater than 1, and the preset decrease coefficient is a number greater than 0 and less than 1. When the air humidity is within the preset air humidity range, the system calls the baseline control parameters to control the operation of the nano-water ion module. When the air humidity is less than the lower limit of the preset air humidity range, the system multiplies the baseline control parameters with the preset increase coefficient to obtain low humidity control parameters, and controls the operation of the nano-water ion module according to the low humidity control parameters. When the air humidity is greater than the upper limit of the preset air humidity range, the system multiplies the baseline control parameters with the preset decrease coefficient to obtain high humidity control parameters, and controls the operation of the nano-water ion module according to the high humidity control parameters.

[0072] In a specific implementation, for example, the optimal humidity range of 40%-60% for the nano-water ion module to generate nano-water ions is set as the preset air humidity range. The control parameter is the module's on-time. The correspondence between the on-times of the air humidity module is shown in Table 1. When the sterilization mode is on, the humidity sensor obtains that the air humidity in the room where the indoor unit is located is 30%, which is less than the lower limit of the preset air humidity range. The module's on-time is 20 minutes, obtained from Table 1. Therefore, the nano-water ion module is powered on for 20 minutes to generate nano-water ions to sterilize the space where the indoor unit is located. The data in the table can also be set to other values ​​according to the actual situation, which does not constitute a limitation on this embodiment.

[0073] Table 1

[0074] H<40％ 20 minutes 40％≤H≤60％ 10 minutes H>60％ 5 minutes

[0075] In this embodiment, the indoor unit of the air conditioner is equipped with a nano-water ion module for air sterilization. When the sterilization mode is activated, the control parameters of the nano-water ion module are determined according to the air humidity in the space where the indoor unit is located. The operation of the nano-water ion module is controlled according to the control parameters, which solves the technical problem that the nano-water ion module cannot stably generate nano-water ions due to unstable air humidity in the space, and improves the sterilization effect of the air conditioner.

[0076] refer to Figure 4 , Figure 4 This is a flowchart illustrating the second embodiment of the control method for the air conditioner of the present invention.

[0077] Based on the first embodiment described above, the control parameters include the semiconductor turn-on time, the negative high-voltage plate turn-on time, and / or the negative high-voltage plate voltage in the nano-water ion module. In this embodiment, step S22 includes:

[0078] Step S221: Determine whether the air humidity is within the preset air humidity range.

[0079] In this embodiment, the preset air humidity range can be the optimal humidity range for the nano water ion module to generate nano water ions; the semiconductor turn-on time can be the energization time of the semiconductor in the nano water ion module; the negative high voltage plate turn-on time can be the energization time of the negative high voltage plate in the nano water ion module; and the negative high voltage plate voltage can be the energization voltage of the negative high voltage plate in the nano water ion module.

[0080] Step S222: When the air humidity is within the preset air humidity range, the semiconductor turn-on time is determined as the first preset semiconductor turn-on time, the negative high voltage plate turn-on time is determined as the first preset plate turn-on time, and / or the negative high voltage plate voltage is determined as the first preset voltage.

[0081] It is understood that the first preset semiconductor turn-on time can be the energizing time of the semiconductor when the air humidity is within a preset air humidity range; the first preset electrode turn-on time can be the energizing time of the negative high voltage electrode when the air humidity is within a preset air humidity range; the first preset voltage can be the energizing voltage of the negative high voltage electrode when the air humidity is within a preset air humidity range; the first preset semiconductor turn-on time, the first preset electrode turn-on time, and the first preset voltage can be obtained through experimental calibration.

[0082] In a specific implementation, for example, the optimal humidity range for the nano-water ion module to generate nano-water ions is 40%-60%. This humidity range is set as a preset air humidity range. The first preset semiconductor turn-on time is X1, the first preset electrode turn-on time is Y1, and the first preset voltage is Z1. The control parameters of the nano-water ion module, obtained through experimental calibration, are as follows: X1-10 minutes, Y1-30 minutes, Z1-3000 volts. Assuming that the control device obtains the air humidity in the space where the indoor unit is located as 45% through the humidity sensor, the control device sets the semiconductor turn-on time in the nano-water ion module to 10 minutes, the negative high voltage electrode turn-on time to 30 minutes, and the negative high voltage electrode cigarette lighter to 3000 volts, and controls the operation of the nano-water ion module according to the above parameters.

[0083] Furthermore, when the air humidity is within the optimal humidity range for the nano-water ion module to generate nano-water ions, the nano-water ion module can quickly and stably generate nano-water ions, and the air conditioner's sterilization effect on the space is also the best. In order to ensure that the nano-water ion module operates within the optimal humidity range, after step S221, the method further includes: when the air humidity is not within the preset air humidity range, determining whether the air humidity is greater than the upper limit of the preset air humidity range; when the air humidity is greater than the upper limit of the preset air humidity range, determining whether the dehumidification function of the air conditioner is turned on; when the dehumidification function of the air conditioner is turned on, controlling the air conditioner to dehumidify the space where the indoor unit is located; when the air humidity in the space decreases to within the preset air humidity range, determining the semiconductor turn-on time as the first preset semiconductor turn-on time, determining the negative high-voltage plate turn-on time as the first preset plate turn-on time, and / or determining the negative high-voltage plate voltage as the first preset voltage.

[0084] It is understandable that when the air humidity is greater than the upper limit of the preset air humidity range, it indicates that the air humidity in the space is too high. At this time, it can be determined whether the dehumidification function of the air conditioner is turned on. If it is turned on, the air conditioner is controlled to dehumidify the space where the indoor unit is located to reduce the air humidity to within the preset air humidity range. When the air humidity is reduced to within the preset air humidity range, the control parameters of the nano water ion module are set to the control parameters corresponding to the preset air humidity range.

[0085] It should be understood that if the dehumidification function of the air conditioner is not turned on, the user can be reminded that the indoor air humidity is too high and asked whether to turn on the dehumidification function. If the user confirms that the dehumidification function is turned on, the air conditioner will be controlled to dehumidify the space where the indoor unit is located. If the dehumidification function of the air conditioner is not turned on, the user's historical configuration can also be obtained. If the historical configuration is that the dehumidification function is turned on when the humidity is high, the air conditioner will be automatically controlled to turn on the dehumidification function. If the initial function of the air conditioner is not turned on, the dehumidification function can also be turned on through other means, which will not be listed in this embodiment.

[0086] Furthermore, since the dehumidification function may not be activated, resulting in the inability to reduce the air humidity to within the preset air humidity range, in order to improve the ability of the nano-water ion module to generate nano-water ions in high humidity scenarios, after determining whether the dehumidification function of the air conditioner is activated, the method further includes: when the dehumidification function of the air conditioner is not activated, determining the semiconductor activation duration as a second preset semiconductor activation duration, determining the negative high-voltage plate activation duration as a second preset plate activation duration, and / or determining the negative high-voltage plate voltage as a second preset voltage; wherein, the second preset semiconductor activation duration is less than the first preset semiconductor activation duration, the second preset plate activation duration is greater than the first preset plate activation duration, and the second preset voltage is less than the first preset voltage.

[0087] It is understood that the dehumidification function of the air conditioner is not turned on, which may include the following situations: (1) the dehumidification function is not turned on when the air conditioner is started; (2) after the user receives the message whether to turn on the dehumidification function, the user does not confirm the message within a preset time; (3) the user’s historical configuration information does not obtain the information of turning on the dehumidification function in high humidity; there may also be other situations, which will not be listed one by one in this embodiment.

[0088] It should be understood that the second preset semiconductor turn-on time can be the energizing time of the semiconductor when the air humidity is greater than the upper limit of the preset air humidity range; the second preset electrode turn-on time can be the energizing time of the negative high voltage electrode when the air humidity is greater than the upper limit of the preset air humidity range; the second preset voltage can be the energizing voltage of the negative high voltage electrode when the air humidity is greater than the upper limit of the preset air humidity range; the second preset semiconductor turn-on time, the second preset electrode turn-on time, and the second preset voltage can be obtained by increasing or decreasing the first preset semiconductor turn-on time, the first preset electrode turn-on time, and the first preset voltage, or they can be obtained through experimental calibration, which is not limited in this embodiment.

[0089] It is understandable that if the air humidity in the space is too high, controlling the nano-water ion module by controlling the control parameters corresponding to the preset air humidity range will result in too much and too thick condensate on the condensate enrichment head, making it difficult for the electric field to ionize and decompose water molecules, thus increasing the difficulty of generating nano-water ions. Therefore, in this embodiment, the energizing time of the semiconductor is reduced to reduce the amount of condensate generated on the condensate enrichment head. Due to the high air humidity, the conductivity is enhanced. If the first preset voltage is used, it is easy to cause electric field breakdown and arcing, which will damage the nano-water ion module. Therefore, the energizing voltage of the negative high voltage plate is reduced. After the energizing voltage of the negative high voltage plate is reduced, the electric field strength decreases, and the ability to ionize water molecules decreases. Therefore, the energizing time of the negative high voltage plate is increased to fully ionize water molecules and generate enough nano-water ions.

[0090] In specific implementation, for example: the second preset semiconductor opening time is X2, the second preset electrode opening time is Y2, and the second preset voltage is Z2. The correspondence between air humidity and control parameters can be referred to Table 2. The control device determines whether the air humidity is within the preset air humidity range of 40% ≤ H ≤ 60%. If so, the determined control parameters are: X1 - 10 minutes, Y1 - 30 minutes, Z1 - 3000 volts. If the air humidity is greater than 60%, when the dehumidification function is turned on, the air conditioner is controlled to reduce the air humidity to within the preset air humidity range. When the dehumidification function is not turned on, the determined control parameters are: X2: 5 minutes, Y2: 45 minutes, Z2: 2000 volts. The data in the table can also be set to other values ​​according to the actual situation, which does not constitute a limitation on this embodiment.

[0091] Table 2

[0092]

[0093] In this embodiment, when the air humidity in the space where the indoor unit is located is within a preset air humidity range, the semiconductor turn-on time is determined as the first preset semiconductor turn-on time, the negative high voltage plate turn-on time is determined as the first preset plate turn-on time, and / or the negative high voltage plate voltage is determined as the first preset voltage, thereby improving the efficiency of the nano water ion module in generating nano water ions and enhancing the sterilization effect of the air conditioner.

[0094] refer to Figure 5 , Figure 5 This is a flowchart illustrating the third embodiment of the control method for the air conditioner of the present invention.

[0095] Based on the above embodiments, in this embodiment, after step S221, the method further includes:

[0096] Step S2211: When the air humidity is not within the preset air humidity range, determine whether the air humidity is less than the lower limit of the preset air humidity range;

[0097] Step S2212: When the air humidity is less than the lower limit of the preset air humidity range, determine whether the air conditioner has a humidification function.

[0098] In this embodiment, when the air humidity is less than the preset air humidity range, it indicates that the air humidity is too low. It is then determined whether the air conditioner has a humidification function. If the air conditioner has a humidification function, it can be controlled to humidify the space where the indoor unit is located to increase the air humidity. When the air humidity is increased to within the preset air humidity range, the control parameters corresponding to the preset air humidity range are determined to be the control parameters of the nano water ion module.

[0099] Step S2213: When the air conditioner has a humidification function, the water in the humidification water tank of the air conditioner is transferred to the condensate enrichment head of the nano water ion module.

[0100] It is understandable that if the air conditioner has a humidification function, but the humidification function is not turned on or cannot be turned on, the water in the humidification water tank can be transferred to the condensate enrichment head through a pipe. The reason why the water in the humidification water tank is introduced for ionization only when the humidity is low, rather than under all humidity conditions, is that the semiconductor condensate will form a uniform water film and water layer on the surface of the condensate enrichment head. Directly introducing the water in the humidification water tank will cause uneven water distribution on the condensate enrichment head, and the amount of water that can be collected will also be reduced, affecting the discharge and the generation of negative water ions. Therefore, this embodiment prioritizes the use of semiconductor cooling to enrich water, and only introduces the water in the humidification water tank under low humidity conditions.

[0101] Step S2214: When transferring water from the humidifying water tank to the condensate enrichment head, the semiconductor turn-on time is determined as a third preset semiconductor turn-on time, the negative high voltage plate turn-on time is determined as a third preset plate turn-on time, and / or the negative high voltage plate voltage is determined as a third preset voltage; wherein, the third preset semiconductor turn-on time is less than the first preset semiconductor turn-on time, the third preset plate turn-on time is greater than the first preset plate turn-on time, and the third preset voltage is greater than the first preset voltage.

[0102] In this embodiment, since water can be directly introduced into the humidification tank, the third preset semiconductor turn-on time can be set to a time close to or equal to 0 minutes. Directly introducing water into the humidification tank increases the difficulty of ionization of water molecules. Therefore, the start time of the third preset electrode plate is longer than the start time of the first preset electrode plate, and the third preset voltage is also longer than the first preset voltage.

[0103] Furthermore, since the humidification function may not be turned on or the air conditioner may not have a humidification function, resulting in the inability to raise the air humidity to within the preset air humidity range and the inability to directly introduce water from the humidification water tank, in order to improve the ability of the nano-water ion module to generate nano-water ions in low humidity scenarios, after determining whether the air conditioner has a humidification function, the method further includes: when the air conditioner does not have a humidification function, determining the semiconductor on-time as a fourth preset semiconductor on-time, determining the negative high-voltage plate on-time as a fourth preset plate on-time, and / or determining the negative high-voltage plate voltage as a fourth preset voltage; wherein, the fourth preset semiconductor on-time is longer than the first preset semiconductor on-time, the fourth preset plate on-time is longer than the first preset plate on-time, and the fourth preset voltage is greater than the first preset voltage.

[0104] Understandably, if the air humidity in the space is too low, there will be too little condensate on the condensate enrichment head, which will not be able to ionize and decompose water molecules, thus failing to generate nano water ions. Therefore, the semiconductor on-time is increased to increase the amount of condensate on the condensate enrichment head, while the on-time of the negative high-voltage plate and the voltage of the negative high-voltage plate are increased to fully decompose water molecules.

[0105] In specific implementations, for example: the fourth preset semiconductor turn-on duration is X4, the fourth preset electrode turn-on duration is Y4, and the fourth preset voltage is Z4. The relationship between air humidity and each control parameter can be referred to Table 3. When the air humidity is less than the lower limit of the preset air humidity range, if water from the humidifying water tank is introduced to the condensate enrichment head, the control parameters of the nano water ion module are determined to be: X3: 0 minutes, Y3: 40 minutes, Z3: 3500 volts. If the air conditioner has no humidification function or cannot introduce water from the humidifying water tank, the control parameters of the nano water ion module are determined to be: X4: 20 minutes, Y4: 60 minutes, Z4: 4500 volts. The data in the table can also be set to other values ​​according to the actual situation, which does not constitute a limitation on this embodiment.

[0108] In this embodiment, when the air humidity is less than the lower limit of the preset air humidity range, it is determined whether the air conditioner has a humidification function. If it does, the water in the humidification water tank can be transferred to the negative electrode of the condensate water, and the semiconductor opening time is determined to the third preset semiconductor opening time, the negative high voltage plate opening time is determined to the third preset plate opening time, and / or the negative high voltage plate voltage is determined to the third preset voltage. This improves the generation efficiency of nano water ions in low humidity scenarios and enhances the sterilization effect of the air conditioner.

[0109] Furthermore, this embodiment of the invention also proposes a storage medium storing a control program for an air conditioner, wherein when the control program is executed by a processor, it implements the steps of the air conditioner control method described above.

[0110] Reference Figure 6 , Figure 6 This is a structural block diagram of the control device of the air conditioner of the present invention in a first embodiment. The indoor unit of the air conditioner is equipped with a nano water ion module for air sterilization.

[0111] like Figure 6 As shown, the control device for an air conditioner proposed in this embodiment of the invention includes:

[0112] The acquisition module 10 is used to acquire the air humidity in the space where the indoor unit is located when the sterilization mode is activated.

[0113] Understandably, referring to Figure 3 , Figure 3 This is a schematic diagram of the nano-water ion module. The nano-water ion module includes a semiconductor heat sink A, a semiconductor cooling electrode B, a condensate enrichment head C, and a negative high-voltage plate D. The semiconductor cooling electrode B is grounded, and the negative high-voltage plate D is connected to a high-voltage power supply. When the semiconductor is energized, the semiconductor heat sink A dissipates heat, and the semiconductor cooling electrode B cools. Moisture in the air near the condensate enrichment head condenses to form water droplets. The semiconductor cooling electrode B is grounded and forms a high-voltage electric field with the negative high-voltage plate D. Under the action of the electric field force, water molecules break down and separate to form free radicals and nano-water ions. If the air conditioner has a humidification function, the humidification water tank can be connected to the condensate enrichment head C through a pipe, and the water in the humidification water tank can be directly transported to the condensate enrichment head C for ionization.

[0114] It should be understood that the sterilization mode can be a mode that generates nano-water ions to sterilize the space by controlling the operation of the nano-water ion module. The sterilization mode can be turned on by the user during the operation of the air conditioner, or it can be turned on automatically when the sterilization time set by the user is reached, or it can be turned on by other means. This embodiment does not impose any restrictions here. In this embodiment, the humidity of the air in the space can be obtained by a humidity sensor installed in the air conditioner.

[0115] The determination module 20 is used to determine the control parameters of the nano water ion module based on the air humidity.

[0116] In this embodiment, the control parameters can be parameters that control the operation of the nano-water ion module set in the air conditioner. The control parameters include parameters such as the power-on time and power-on voltage of the nano-water ion module. The mapping relationship between air humidity and control parameters can be preset, and the control parameters of the nano-water ion module are determined according to the air humidity obtained by the humidity sensor and the preset mapping relationship.

[0117] The control module 30 is used to control the nano water ion module through the control parameters.

[0118] In a specific implementation, assuming that during the operation of the air conditioner, the user sends a command to activate the sterilization mode via the remote control, the control device collects the air humidity of the indoor space where the indoor unit is located through the humidity sensor when the air conditioner activates the sterilization mode according to the command, determines the control parameters of the nano water ion module based on the air humidity and the preset mapping relationship, and controls the nano water ion module to perform space sterilization based on the control parameters.

[0119] Furthermore, in order to enable the nano-water ion module to stably generate nano-water ions and improve the sterilization effect of the air conditioner, the determining module 20 is also used to: compare the air humidity with a preset air humidity range.

[0120] It is understood that the preset air humidity range can be a pre-set air humidity range; the preset air humidity range can be set in the following ways: (1) the optimal humidity range for the nano water ion module to generate nano water ions is preset as the air humidity range; (2) the preset air humidity range is determined according to the humidity range of the air humidity value in the sales area or region of the air conditioner. The humidity range can also be set in other ways, which are not limited in this embodiment.

[0121] The control parameters of the nano-water ion module are determined based on the comparison results of air humidity.

[0122] It is understandable that the comparison results include air humidity within the preset air humidity range, air humidity greater than the upper limit of the preset air humidity range, and air humidity less than the lower limit of the preset air humidity range.

[0123] In this embodiment, a first control parameter can be preset to indicate that the air humidity is within a preset air humidity range; a second control parameter can be preset to indicate that the air humidity is greater than the upper limit of the preset air humidity range; and a third control parameter can be preset to indicate that the air humidity is less than the lower limit of the preset air humidity range. When controlling the nano-water ion module, the first, second, or third control parameter is called based on the comparison result between the air humidity and the preset air humidity range. Alternatively, a baseline control parameter can be preset to indicate that the air humidity is within the preset air humidity range, and a preset threshold can be set. The system uses a high coefficient and a preset reduction coefficient. The preset increase coefficient is a number greater than 1, and the preset decrease coefficient is a number greater than 0 and less than 1. When the air humidity is within the preset air humidity range, the system calls the baseline control parameters to control the operation of the nano-water ion module. When the air humidity is less than the lower limit of the preset air humidity range, the system multiplies the baseline control parameters with the preset increase coefficient to obtain low humidity control parameters, and controls the operation of the nano-water ion module according to the low humidity control parameters. When the air humidity is greater than the upper limit of the preset air humidity range, the system multiplies the baseline control parameters with the preset decrease coefficient to obtain high humidity control parameters, and controls the operation of the nano-water ion module according to the high humidity control parameters.

[0124] In a specific implementation, for example, the optimal humidity range of 40%-60% for the nano-water ion module to generate nano-water ions is set as the preset air humidity range. The control parameter is the module's on-time. The correspondence between the on-times of the air humidity module is shown in Table 1. When the sterilization mode is on, the humidity sensor obtains that the air humidity in the room where the indoor unit is located is 30%, which is less than the lower limit of the preset air humidity range. The module's on-time is 20 minutes, obtained from Table 1. Therefore, the nano-water ion module is powered on for 20 minutes to generate nano-water ions to sterilize the space where the indoor unit is located. The data in the table can also be set to other values ​​according to the actual situation, which does not constitute a limitation on this embodiment.

[0126] H<40％ 20 minutes 40％≤H≤60％ 10 minutes H>60％ 5 minutes

[0127] In this embodiment, the indoor unit of the air conditioner is equipped with a nano-water ion module for air sterilization. When the sterilization mode is activated, the control parameters of the nano-water ion module are determined according to the air humidity in the space where the indoor unit is located. The operation of the nano-water ion module is controlled according to the control parameters, which solves the technical problem that the nano-water ion module cannot stably generate nano-water ions due to unstable air humidity in the space, and improves the sterilization effect of the air conditioner.
