Description

Technical Field

[0001] This invention relates to the field of electrical equipment technology, specifically to an air purifier, a sterilization and disinfection method for the air purifier, and an apparatus. Background Technology

[0002] Air filtration technology is a highly efficient air purification technology that uses filters to intercept dust and microorganisms in the air. However, in actual use, the intercepted microorganisms accumulate on the filter over time, multiply and grow, which in turn causes a decline in indoor air quality and harms human health.

[0003] Low-temperature plasma technology, as a safe, efficient, and convenient sterilization and disinfection technology, generates a large number of high-energy electrons and highly oxidizing active groups during the discharge process. These can quickly inactivate bacteria upon contact. By utilizing plasma technology, filters can be rapidly sterilized and disinfected in real time, which helps protect human health and reduces the frequency of filter cleaning and replacement.

[0004] However, when a plasma generator discharges, there is dielectric loss, which dissipates heat to the external environment, causing the temperature around the device to rise. Long-term operation will damage the filter material that is close to the plasma generator. Summary of the Invention

[0005] In view of this, the present invention provides an air purifier, a sterilization and disinfection method and apparatus for the air purifier, to solve the problem that the filter material close to the plasma generator may be damaged when using a plasma generator to sterilize the filter.

[0006] In a first aspect, embodiments of the present invention provide a sterilization and disinfection method for an air purifier, the method comprising the following steps: receiving a command to turn on a plasma generator; and when the command to turn on a plasma generator is received, controlling the plasma generator to operate intermittently.

[0007] The sterilization and disinfection method for air purifiers provided in this embodiment of the invention controls the plasma generator to work intermittently when a command to turn on the plasma generator is received; that is, the plasma generator works for a period of time, then stops working, and then starts working again, and so on in a cycle; when the plasma generator stops working, it can not only dissipate heat, but also has no dielectric loss, so the temperature of the plasma generator itself will decrease, thereby solving the problem of damage to filter materials that are close to the plasma generator.

[0008] Additionally, it should be noted that when using the substance generated by the plasma generator to disinfect the filter, the substance needs to first come into full contact with the bacteria. In the sterilization and disinfection method of the air purifier in this embodiment of the invention, the plasma generator operates intermittently when a start-up command is received. Even when the plasma generator stops operating, although it cannot generate plasma, this does not affect the full contact between the substance generated and the bacteria. Therefore, it does not affect the disinfection effect of the plasma on the filter. Compared to the continuous operation of the plasma generator during filter disinfection, the intermittent operation of the plasma generator in this embodiment of the invention improves the energy utilization efficiency of the plasma generator.

[0009] In one optional implementation, controlling the intermittent operation of the plasma generator includes: after the plasma generator is turned on, acquiring a first parameter value of the plasma generator; when the first parameter value reaches a preset first threshold, turning off the plasma generator; after the plasma generator is turned off, acquiring a second parameter value of the plasma generator; when the second parameter value reaches a preset second threshold, turning on the plasma generator and returning to the step of acquiring the first parameter value of the plasma generator.

[0010] This ensures that the plasma generator can operate intermittently.

[0011] In one optional implementation, the first parameter value includes the operating time of the plasma generator and the temperature of the discharge plate in the plasma generator; and / or, the second parameter value includes the operating time of the plasma generator and the temperature of the discharge plate in the plasma generator.

[0012] By controlling the intermittent operation of the plasma generator according to its operating time and / or the temperature of the discharge plate in the plasma generator, it is possible to ensure that the temperature of the plasma generator does not become too high during its intermittent operation, thus better solving the problem of damage to filter materials that are close to the plasma generator.

[0013] In one alternative implementation, turning on the air purifier includes controlling the air purifier's fan to operate at a preset first speed.

[0014] This allows the air flowing through the air purifier to enter the plasma generator.

[0015] In one alternative implementation, after the plasma generator is turned off, the method further includes the following step: controlling the fan to operate at a preset second rotational speed, wherein the second rotational speed is greater than the first rotational speed.

[0016] Therefore, when the plasma generator is turned off, the fan speed will be increased to accelerate the heat dissipation of the plasma generator.

[0017] In one optional implementation, after controlling the plasma generator to operate intermittently, the method further includes: obtaining the cumulative operating time of the air purifier from the last deep disinfection of the filter to the current time; determining the disinfection mode for disinfecting the filter based on the cumulative operating time; and determining the operating time threshold of the plasma generator when operating intermittently, corresponding to the disinfection mode.

[0018] This allows air purifiers to be suitable for different application scenarios.

[0019] In one optional implementation, the sterilization and disinfection method of the air purifier further includes the following steps: determining whether the cumulative running time is greater than a preset fourth threshold; when the cumulative running time is greater than or equal to the fourth threshold, the disinfection mode for disinfecting the filter is deep disinfection; when the cumulative running time is less than the fourth threshold, the disinfection mode for disinfecting the filter is shallow disinfection.

[0020] This allows for the use of different disinfection methods for different filters.

[0021] In one optional implementation, determining the disinfection mode for the filter based on the cumulative runtime includes: determining whether the cumulative runtime is greater than a preset fourth threshold; when the cumulative runtime is greater than or equal to the fourth threshold, the disinfection mode for the filter is deep disinfection; when the cumulative runtime is less than the fourth threshold, the disinfection mode for the filter is shallow disinfection.

[0022] This allows for accurate classification of filters.

[0023] Secondly, embodiments of the present invention also provide a sterilization and disinfection device for an air purifier, the device including an instruction receiving module and a plasma generator control module; the instruction receiving module is used to issue an instruction to turn on the plasma generator; when the instruction to turn on the plasma generator is received, the plasma generator control module is used to control the plasma generator to work intermittently.

[0024] Thirdly, embodiments of the present invention also provide a computer device, including a memory and a processor, which are interconnected. The memory stores computer instructions, and the processor executes the computer instructions to perform the sterilization and disinfection method of the air purifier described in the first aspect or any of its corresponding embodiments.

[0025] Fourthly, embodiments of the present invention also provide an air purifier, including the computer device of the third aspect.

[0026] In one alternative embodiment, the air purifier further includes a fan, a filter, and a plasma generator; the fan is communicatively connected to a computer device to provide power for the flow of air within the air purifier; the filter is used to filter the air flowing through the air purifier; and the plasma generator is communicatively connected to the computer device to disinfect the air flowing through the air purifier and / or the filter.

[0027] In one alternative implementation, the plasma generator employs surface dielectric barrier discharge.

[0028] Fifthly, embodiments of the present invention also provide a computer-readable storage medium storing computer instructions, which are used to cause a computer to execute the sterilization and disinfection method of the air purifier described in the first aspect or any corresponding embodiment.

[0041] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] According to an embodiment of the present invention, a sterilization and disinfection method for an air purifier is provided. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0043] This embodiment provides a sterilization and disinfection method for an air purifier, which can be used in computer equipment. Figure 1 This is a flowchart of a filter sterilization method in an air purifier according to an embodiment of the present invention, such as... Figure 1 As shown, the process includes the following steps:

[0044] Step S101: Receive the command to turn on the plasma generator.

[0045] Step S102: When a command to turn on the plasma generator is received, control the plasma generator to operate intermittently.

[0046] The sterilization and disinfection method for air purifiers provided in this embodiment of the invention controls the plasma generator to work intermittently when a command to turn on the plasma generator is received; that is, the plasma generator works for a period of time, then stops working, and then starts working again, and so on in a cycle; when the plasma generator stops working, it can not only dissipate heat, but also has no dielectric loss, so the temperature of the plasma generator itself will decrease, thereby solving the problem of damage to filter materials that are close to the plasma generator.

[0047] Additionally, it should be noted that when using the substance generated by the plasma generator to disinfect the filter, the substance needs to first come into full contact with the bacteria. In the sterilization and disinfection method of the air purifier in this embodiment of the invention, the plasma generator operates intermittently when a start-up command is received. Even when the plasma generator stops operating, although it cannot generate plasma, this does not affect the full contact between the substance generated and the bacteria. Therefore, it does not affect the disinfection effect of the plasma on the filter. Compared to the continuous operation of the plasma generator during filter disinfection, the intermittent operation of the plasma generator in this embodiment of the invention improves the energy utilization efficiency of the plasma generator.

[0048] This embodiment provides a sterilization and disinfection method for an air purifier, which can be used in computer equipment. Figure 2 This is a flowchart of another air purifier filter sterilization method according to an embodiment of the present invention, such as... Figure 2 As shown, the process includes the following steps:

[0049] Step S201: After the air purifier is turned on, when a command to turn on the plasma generator is received, the plasma generator in the air purifier is turned on.

[0050] Step S2021: After the plasma generator is turned on, obtain the first parameter value of the plasma generator.

[0051] Specifically, the first parameter value includes the operating time of the plasma generator and the temperature of the discharge plate in the plasma generator.

[0052] For example, when a plasma generator uses surface dielectric barrier discharge (SDBD), the temperature of the discharge plate in the plasma generator refers to the surface temperature of the ceramic dielectric in the plasma generator.

[0053] Step S2022: When the value of the first parameter reaches the preset first threshold, the plasma generator is turned off.

[0054] Specifically, the first threshold can be determined experimentally. For example, when the plasma generator is an SDBD and the first parameter is the surface temperature of the ceramic medium in the plasma generator, the first threshold can be 80°C; when the plasma generator is an SDBD and the first parameter is the operating time of the plasma generator, the first threshold can be 2.5 min.

[0055] Step S2023: After the plasma generator is turned off, obtain the second parameter value of the plasma generator.

[0056] Specifically, the second parameter values ​​include the operating time of the plasma generator and the temperature of the discharge plate in the plasma generator.

[0057] As mentioned above, when the plasma generator uses SDBD, the temperature of the discharge plate in the plasma generator refers to the surface temperature of the ceramic medium in the plasma generator.

[0058] Specifically, the second parameter values ​​include the operating time of the plasma generator and the temperature of the discharge plate in the plasma generator.

[0059] Step S2024: When the value of the second parameter reaches the preset second threshold, turn on the plasma generator and return to step S2021.

[0060] Specifically, the second threshold can be determined experimentally. For example, when the plasma generator is an SDBD and the second parameter value is the surface temperature of the ceramic medium in the plasma generator, the second threshold can be room temperature. This is because when the plasma generator first operates, it operates at room temperature until the first parameter value reaches the preset first threshold. When the first parameter value is the operating time of the plasma generator, heating is performed at room temperature each time it operates, ensuring that the plasma generator reaches essentially the same temperature each time it operates.

[0061] Step S203: Obtain the actual working time of the plasma generator.

[0062] Step S204: When the actual working time reaches the preset third threshold, control the plasma generator to stop working.

[0063] In other words, during the execution of steps S2021 to S2024, the actual working time of the plasma generator is obtained, and when the actual working time reaches the preset third threshold, the plasma generator is controlled to stop working.

[0064] The sterilization and disinfection method for air purifiers provided in this embodiment, after the air purifier is turned on, controls the plasma generator to operate intermittently upon receiving an activation command. The intermittent operation of the plasma generator is controlled based on its operating duration and / or the temperature of the discharge plate within the plasma generator. Since the plasma generator can dissipate heat and there is no dielectric loss when it stops operating, its temperature decreases. Therefore, it ensures that the temperature of the plasma generator does not become excessively high during its intermittent operation, effectively addressing the problem of damage to filter materials located close to the plasma generator.

[0065] This embodiment provides a sterilization and disinfection method for an air purifier, which can be used in computer equipment. Figure 3 This is a flowchart of a filter sterilization method in an air purifier according to an embodiment of the present invention, as shown below. Figure 3 As shown, the process includes the following steps:

[0066] Step S301: Control the air purifier fan to operate at a preset first speed and turn on the plasma generator in the air purifier.

[0067] This is because the fan provides the power for air to circulate within the air purifier. Turning on the fan turns on the air purifier.

[0068] Step S3021: After the plasma generator is turned on, obtain the first parameter value of the plasma generator.

[0069] Specifically, the first parameter value includes the operating time of the plasma generator and the temperature of the discharge plate in the plasma generator.

[0070] Step S3022: When the first parameter value reaches the preset first threshold, the plasma generator is turned off, and the fan is controlled to operate at a preset second speed, wherein the second speed is greater than the first speed.

[0071] In other words, when the plasma generator is turned off, the fan speed will be increased to accelerate the heat dissipation of the plasma generator.

[0072] Step S3023: After the plasma generator is turned off, obtain the second parameter value of the plasma generator.

[0073] Specifically, the second parameter values ​​include the operating time of the plasma generator and the temperature of the discharge plate in the plasma generator.

[0074] Step S3024: When the value of the second parameter reaches the preset second threshold, turn on the plasma generator and return to step S3021.

[0075] It should be noted that after returning to step S3021, the fan operates at a preset first speed.

[0076] Step S303: Obtain the actual working time of the plasma generator.

[0077] Step S304: When the actual working time reaches the preset third threshold, control the plasma generator to stop working.

[0078] In other words, during the execution of steps S3021 to S3024, the actual working time of the plasma generator is obtained, and when the actual working time reaches the preset third threshold, the plasma generator is controlled to stop working.

[0079] The sterilization and disinfection method for air purifiers provided in this embodiment, after the air purifier is turned on, controls the plasma generator to operate intermittently upon receiving an activation command. During these intermittent operations, the intermittent operation of the plasma generator is controlled not only based on its operating duration and / or the temperature of the discharge plate within the plasma generator, but also by increasing the fan speed to accelerate heat dissipation. Since the plasma generator not only dissipates heat when it stops operating, but also experiences no dielectric loss, its temperature decreases. This ensures that the temperature does not become excessively high during the intermittent operation of the plasma generator, effectively addressing the problem of damage to filter materials located close to the plasma generator.

[0080] This embodiment provides a sterilization and disinfection method for an air purifier, which can be used in computer equipment. Figure 4 This is a flowchart of another air purifier filter sterilization method according to an embodiment of the present invention, such as... Figure 4 As shown, the process includes the following steps:

[0081] Step S401: Control the air purifier's fan to operate at a preset first speed.

[0082] Step S4021: Obtain the cumulative running time of the air purifier from the last deep disinfection of the filter to the current moment.

[0083] Step S4022: Determine whether the cumulative runtime is greater than the preset fourth threshold;

[0084] Step S4023: When the cumulative runtime is greater than or equal to the fourth threshold, the disinfection mode for the filter is deep disinfection; when the cumulative runtime is less than the fourth threshold, the disinfection mode for the filter is shallow disinfection.

[0085] The fourth threshold can be determined based on the specific characteristics of the air purifier.

[0086] Step S4031: After the plasma generator is turned on, obtain the first parameter value of the plasma generator.

[0087] Specifically, the first parameter value includes the operating time of the plasma generator and the temperature of the discharge plate in the plasma generator.

[0088] Step S4032: When the first parameter value reaches the preset first threshold, the plasma generator is turned off, and the fan is controlled to operate at a preset second speed, wherein the second speed is greater than the first speed.

[0089] Step S4033: After the plasma generator is turned off, obtain the second parameter value of the plasma generator.

[0090] Specifically, the second parameter values ​​include the operating time of the plasma generator and the temperature of the discharge plate in the plasma generator.

[0091] Step S4034: When the value of the second parameter reaches the preset second threshold, turn on the plasma generator and return to step S4031.

[0092] Step S404: Obtain the actual working time of the plasma generator.

[0093] Step S405: Obtain the working duration threshold of the plasma generator during intermittent operation corresponding to the disinfection mode.

[0094] Among them, the working time threshold of the plasma generator when it operates intermittently, which corresponds to the disinfection mode, can be called the third threshold. The working time threshold of the plasma generator when it operates intermittently, which corresponds to deep disinfection, is greater than the working time threshold of the plasma generator when it operates intermittently, which corresponds to shallow disinfection.

[0095] Step S406: When the actual working time reaches the preset third threshold, control the plasma generator to stop working.

[0096] The sterilization and disinfection method for air purifiers provided in this embodiment can not only solve the problem of damage to filter materials that are close to the plasma generator; but also, the working time of the plasma generator is different for different disinfection modes, thereby meeting the different needs during the use of air purifiers.

[0097] To more clearly illustrate the sterilization and disinfection method of the air purifier in this embodiment of the invention, a specific example is given. For example... Figures 5-7As shown, the sterilization and disinfection method for air purifiers includes the following steps:

[0098] like Figure 5 As shown, the sterilization and disinfection method for air purifiers includes the following steps:

[0099] (1) Turn on the purification equipment, obtain the cumulative running time of the purification equipment since the last deep disinfection mode, determine the target operating level of the purification equipment based on the cumulative running time, and control the plasma generator to run the filter sterilization mode - shallow / deep disinfection mode based on the target operating level.

[0100] (2) When the cumulative running time since the last deep disinfection mode is less than 30 hours, the operating mode is the first operating mode corresponding to low bacterial concentration - shallow disinfection mode; when the cumulative running time is ≥30 hours, the operating mode is the second operating mode corresponding to high bacterial concentration - deep disinfection mode.

[0101] like Figure 6 As shown, the plasma generator is turned on and run at a wind speed of 600 r / min for 2.5 minutes, then turned off. The wind speed is increased to 1600 r / min for cooling. The temperature on the SDBD board in the plasma generator is monitored. When the temperature drops to room temperature, the plasma generator is turned on again and run at a wind speed of 600 r / min for 2.5 minutes. The above process is repeated. When the cumulative discharge time reaches 1 hour, the plasma generator is turned off to complete the shallow disinfection of the filter. When the cumulative discharge time reaches 3 hours, the plasma generator is turned off to complete the deep disinfection of the filter.

[0102] like Figure 7 As shown, the plasma generator was turned on and operated at a wind speed of 600 r / min for 2.5 minutes. Then, the plasma generator was turned off, and the wind speed was increased to 1600 r / min for cooling. The temperature on the SDBD board in the plasma generator was monitored. When the temperature dropped to room temperature, the plasma generator was turned on again and operated at a wind speed of 600 r / min for 2.5 minutes. This process was repeated until the cumulative discharge time reached 1 hour. Then, the plasma generator was turned off, completing the shallow disinfection of the filter.

[0103] This invention employs a discharge-cooling cyclic disinfection scheme. By program-controlled discharge disinfection time, cooling time, and operating wind speed, the surface temperature of the filter and discharge plate during operation is effectively controlled, reducing damage to the filter and other materials caused by excessive temperature and extending their service life. Simultaneously, the active substances generated during the cyclic discharge process continuously sterilize the filter during the cooling phase, improving energy utilization efficiency and reducing the power required for complete disinfection.

[0104] This embodiment also provides a sterilization and disinfection device for an air purifier, which is used to implement the above embodiments and preferred embodiments; details already described will not be repeated.
