[0025] In order to make the purpose, technical scheme and advantages of the application more clear, the technical scheme of the application will be described clearly and completely below in combination with the specific embodiments of the application and the corresponding drawings. Obviously, the described embodiments are only some of the embodiments of the application, but not all the embodiments. Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the application.

[0026] According to the embodiments of the application, a control method of an air conditioner is provided, the air conditioner comprising a sterilization module, the sterilization module adopting the principle of differential discharge of special-shaped electrode tips, capable of simultaneously generating a large amount of negative ions, a small amount of positive ions and a small amount of ozone, having the effects of purifying air, air sterilization, dust removal and preventing odor breeding, and capable of being applied in scenes such as air conditioners, fresh air, air purifiers and cars.

[0027] The sterilization module has a normal mode and an intelligent mode. The normal mode is to switch between at least two powers and the running time at each power is fixed. For example, the normal mode is provided with high power and low power, the input power corresponding to the high power is 1.8W and the input current is 150mA, the input power corresponding to the low power is 1W and the input current is 80mA, after the user starts the sterilization module and runs in the normal mode, the sterilization module first runs at high power for t1 time, then switches to low power for t2 time, then switches to high power for t1 time, and then switches to low power for t2 time, and so on, t1 ranges from 1 to 5 hours, and t2 ranges from 12 to 72 hours. In the intelligent mode, the sterilization module switches between at least two powers and controls the running time at each power according to the indoor environment temperature and the indoor relative humidity.

[0028] As shown in the flowchart of an embodiment of the method of the application. The control method of the air conditioner can include steps S110 to S130. Figure 1

[0029] At step S110, after the sterilization module starts to run in the intelligent mode, the indoor environment temperature and the indoor relative humidity are obtained. Temperature sensors and humidity sensors can be provided for real-time sampling, and filtering algorithms can be used to eliminate interference and temperature compensation can be used to correct humidity measurement errors.

[0030] At step S120, the risk level of bacteria breeding in the indoor environment is determined according to the indoor environment temperature and the indoor relative humidity.

[0031] The bacteria breeding speed is closely related to the environment temperature and humidity. In a high-temperature and high-humidity environment, the bacteria metabolism is active and the breeding speed is fast; in a low-temperature and low-humidity environment, the bacteria activity is significantly inhibited and the breeding speed is reduced. Therefore, the bacteria breeding risk level is divided into three risk levels: high risk, medium risk and low risk, so that the system can adjust the sterilization strategy accordingly, i.e., to strengthen sterilization in a high-risk environment and to reduce energy consumption in a low-risk environment.

[0032] ​In some embodiments, in step S120, the specific process of determining the bacteria breeding risk level of the indoor environment according to the indoor environment temperature and the indoor relative humidity includes: judging the size of the indoor environment temperature and the size of the indoor relative humidity; if the indoor environment temperature is greater than or equal to a preset first temperature and the indoor relative humidity is greater than a preset first humidity, determining that the bacteria breeding risk level is high risk; if the indoor environment temperature is less than or equal to a preset second temperature and greater than or equal to a preset third temperature, and the indoor relative humidity is less than a preset second humidity, determining that the bacteria breeding risk level is low risk; if the indoor environment temperature is less than the preset third temperature, determining that the bacteria breeding risk level is low risk; and the bacteria breeding risk level corresponding to the combination of the indoor environment temperature and the indoor relative humidity in other cases is medium risk, where the preset first temperature > the preset second temperature > the preset third temperature, and the preset first humidity > the preset second humidity.

[0033] The high risk means that bacteria are easy to breed, the low risk means that bacteria are not easy to breed, and the medium risk means that the bacteria breeding is general. When the indoor environment is a high-temperature and high-humidity environment and a normal-temperature and high-humidity environment, it is considered that bacteria are easy to breed. The temperature and humidity range corresponding to the high-temperature and high-humidity environment is indoor temperature ≥ 30°C and indoor relative humidity ≥ 80%, and the temperature and humidity range corresponding to the normal-temperature and high-humidity environment is 23°C ≤ indoor temperature ≤ 30°C and indoor relative humidity ≥ 80%. Therefore, the preset first temperature can be set to 23°C, the preset first humidity can be set to 80%, and when 23°C ≤ indoor temperature and indoor relative humidity ≥ 80%, the indoor environment is a high-temperature and high-humidity environment or a normal-temperature and high-humidity environment. At this time, the system determines that the bacteria breeding risk level is high risk, and the sterilization efficiency needs to be enhanced to avoid the increase of the number of bacteria.

[0034] When the indoor environment is a low-temperature and medium-humidity environment or an extremely low-temperature environment, it is considered that bacteria are not easy to breed. The temperature and humidity range corresponding to the low-temperature and medium-humidity environment is 5°C ≤ indoor temperature ≤ 15°C and indoor relative humidity < 50%, and the temperature range corresponding to the extremely low-temperature environment is indoor temperature ≤ 5°C. Therefore, the preset second temperature can be set to 15°C, the preset second humidity can be set to 50%, and the preset third temperature can be set to 5°C. When 5°C ≤ indoor temperature ≤ 15°C and indoor relative humidity < 50%, the indoor environment is a low-temperature and medium-humidity environment, and when indoor temperature ≤ 5°C, the indoor environment is an extremely low-temperature environment. At this time, the system determines that the bacteria breeding risk level is low risk, and the sterilization module can play a sterilization effect at a low power, so that the running time of the sterilization module at a high power can be reduced to reduce energy consumption.

[0035] The bacteria breeding risk level corresponding to the temperature and humidity range outside the high-risk and low-risk ranges is a medium-risk, such as when 5≤ indoor temperature≤15℃ and indoor relative humidity≥50%, or indoor temperature≥23℃ and indoor relative humidity<80%, or 15℃≤indoor temperature≤23℃, etc. At this time, the running time at high power is appropriately reduced, and the running time at low power is increased, so as to balance the sterilization effect and energy saving of the system compared with the high-risk.

[0036] In some embodiments, more bacteria breeding risk levels can also be divided on the basis of high-risk, medium-risk, and low-risk, each risk level corresponds to different running time, and the high-power running time under higher bacteria breeding risk>the high-power running time under lower bacteria breeding risk, and the low-power running time under higher bacteria breeding risk<the low-power running time under lower bacteria breeding risk, i.e. the running time is set in a ladder form, so as to match the sterilization effect with the current environment.

[0037] In some embodiments, more preset powers can also be set on the basis of high power and low power, and in the same bacteria breeding risk level, the running time of the sterilization module under higher power<the running time under lower power. That is, the running time of the sterilization module under different preset powers is set in a ladder form, so as to match the sterilization efficiency with the current environment, and the bacteria breeding needs a certain time, so the high power and low power are cycled, which can ensure sterilization and reduce power consumption.

[0038] At step S130, the sterilization module is controlled to switch between at least two preset powers and control the running time of the sterilization module under the at least two preset powers according to the bacteria breeding risk level.

[0039] The preset power is at least two, such as high power and low power. The sterilization intensity of the sterilization module is high at high power, which can quickly kill most bacteria. The sterilization module has low energy consumption at low power, while avoiding the growth of bacteria. In the intelligent mode, the running time of the sterilization module under each power is controlled according to the indoor temperature and humidity, and the risk level is re-evaluated and the parameters are adjusted after each cycle is completed, so as to not only improve the sterilization efficiency, but also reduce the energy consumption of the sterilization module.

[0040] In some embodiments, the at least two preset powers include a preset first power and a preset second power; the preset first power > the preset second power, i.e., the preset first power is a high power and the preset second power is a low power. In step S130, the specific process of controlling the running time length of the sterilization module at the at least two preset powers according to the bacterial breeding risk level includes: in the case that the bacterial breeding risk level is a high risk, controlling the sterilization module to run at the preset first power for a first time length and then switching to the preset second power for a second time length; in the case that the bacterial breeding risk level is a medium risk, controlling the sterilization module to run at the preset first power for a third time length and then switching to the preset second power for a fourth time length; in the case that the bacterial breeding risk level is a low risk, controlling the sterilization module to run at the preset first power for a fifth time length and then switching to the preset second power for a sixth time length; wherein the first time length > the third time length > the fifth time length, the second time length > the fourth time length > the sixth time length, the first time length < the second time length, the third time length < the fourth time length, and the fifth time length < the sixth time length.

[0041] When running at a high power, the sterilization module has a stronger sterilization capability and can quickly kill bacteria in the air or on the surface of an object; however, the energy consumption is higher and additional effects may be generated in the high power state. When running at a low power, the sterilization capability is weaker, but the energy consumption is lower and the safety is higher, and it is suitable for maintaining the sterilization effect for a long time. Under the same risk level, a balance needs to be found between quickly suppressing bacteria and continuously controlling and saving costs, i.e., first using a short time of high power to quickly reduce the number of bacteria and then using a long time of low power to maintain the sterilization effect, so as to ensure the efficiency and avoid the disadvantages of long-term high power running. Therefore, under the same risk level, the running time length of the high power < the running time length of the low power, i.e., the first time length < the second time length, the third time length < the fourth time length, and the fifth time length < the sixth time length.

[0042] The bacterial breeding risk level being a high risk means that the current environment is very suitable for the rapid reproduction of bacteria, a large number of bacteria may exist and continuously breed; under a medium risk, the environment is suitable for the slow reproduction of bacteria and the number of bacteria is medium; under a low risk, the environment is not conducive to the growth of bacteria and the number of bacteria is small and the reproduction is slow. The corresponding sterilization strategy needs to match the risk level: the higher the risk, the more powerful and fast suppression is needed; the lower the risk, the more emphasis is placed on moderate maintenance. Therefore, a longer time of high power sterilization is needed to quickly control the situation under a high risk, and the maintenance time of the low power can be relatively shortened, i.e., the first time length > the third time length > the fifth time length, and the second time length > the fourth time length > the sixth time length. The first time length can be set to 5h, the second time length can be set to 12h, the third time length can be set to 3h, the fourth time length can be set to 48h, the fifth time length can be set to 1h, and the sixth time length can be set to 72h.

[0043] In the high risk of bacterial growth, the sterilization module is first operated at high power for 5 hours, and then operated at low power for 12 hours, and the above process is repeated; in the medium risk of bacterial growth, the sterilization module is first operated at high power for 3 hours, and then operated at low power for 48 hours, and the above process is repeated; in the low risk of bacterial growth, the sterilization module is first operated at high power for 1 hour, and then operated at low power for 72 hours, and the above process is repeated. That is, in the environment where bacteria are easy to grow, the running time of high power is prolonged and the running time of low power is reduced, and in the environment where bacteria are not easy to grow, the running time of high power is reduced and the running time of low power is prolonged. Thus, the sterilization effect in different environments is ensured, the energy consumption is significantly reduced, the equipment life is prolonged, the full-automatic adaptation is realized, and the user experience is improved.

[0044] In some embodiments, the method further comprises: after determining the bacterial growth risk level of the room, controlling the running proportion of the sterilization module at the at least two preset powers according to the bacterial growth risk level; and the running period of the sterilization module is a fixed time length.

[0045] Specifically, if the sterilization module has a fixed total time length as a running period, the sterilization efficiency can be adjusted by controlling the running time length proportion of the sterilization module at each power. Such control can avoid the sterilization interval disorder caused by the non-fixed running period, the sterilization effect is more stable, and the controllability of energy consumption is stronger.

[0046] In some embodiments, the specific process of controlling the running proportion of the sterilization module at the at least two preset powers according to the bacterial growth risk level comprises: in the case that the bacterial growth risk level is high risk, controlling the sterilization module to run at a preset first power with a first time length proportion and to run at a preset second power with a second time length proportion; in the case that the bacterial growth risk level is medium risk, controlling the sterilization module to run at the preset first power with a third time length proportion and to run at the preset second power with a fourth time length proportion; in the case that the bacterial growth risk level is low risk, controlling the sterilization module to run at the preset first power with a fifth time length proportion and to run at the preset second power with a sixth time length proportion; wherein the first time length proportion > the third time length proportion > the fifth time length proportion, and the second time length proportion < the fourth time length proportion < the sixth time length proportion.

[0047] In a high-risk environment, bacteria multiply at a very fast speed and can breed in large quantities in a short time, at which time a higher proportion of high-power operation is needed to quickly reduce the bacterial base by using the strong sterilization capacity to avoid bacterial flooding. The main role of low power is to maintain the sterilization effect. When the bacteria are greatly suppressed by high power in a high-risk environment, there is no need for long-term low-power operation to prevent rebound. Conversely, in a low-risk environment, bacteria multiply slowly, and the proportion of high power only needs to be maintained at a low level to control the number of bacteria, and the proportion of low power can be increased to save energy to the maximum extent while ensuring the effect and achieve the balance of sterilization on demand. Therefore, the first time length proportion > the third time length proportion > the fifth time length proportion, and the second time length proportion < the fourth time length proportion < the sixth time length proportion. For example, the running cycle of the sterilization module is 24h, in a high-risk environment, the sterilization module first runs at high power for 7.2h (30% of the proportion), and then runs at low power for 16.8h (70% of the proportion), and so on. In a medium-risk environment, the sterilization module first runs at high power for 4.8h (20% of the proportion), and then runs at low power for 19.2h (80% of the proportion), and so on. In a low-risk environment, the sterilization module first runs at high power for 1.2h (5% of the proportion), and then runs at low power for 22.8h (95% of the proportion), and so on. Thus, the proportion of high power is high in a high-risk environment, ensuring rapid sterilization; the proportion of low power is high in a low-risk environment, avoiding energy waste, and achieving the precise balance of sterilization effect and energy consumption.

[0048] By adopting the technical scheme in this embodiment, after the sterilization module of the air conditioner starts to run, the risk level of bacteria breeding in the indoor environment is determined according to the indoor environment temperature and the indoor relative humidity; the sterilization module is controlled to switch between running at at least two preset powers, and the running time length of the sterilization module at the at least two preset powers is controlled according to the risk level of bacteria breeding. Thus, the problem of energy waste caused by the air conditioner sterilization function being unable to be dynamically adjusted is solved, and the balance between sterilization effect and energy saving and consumption reduction is achieved.

[0049] According to the embodiments of the present application, a control device of an air conditioner corresponding to a control method of the air conditioner is also provided. The air conditioner comprises a sterilization module, which adopts the principle of differential discharge of special-shaped electrode tips, can simultaneously generate a large number of negative ions, a small amount of positive ions and a small amount of ozone, has the effects of purifying air, air sterilization, dust removal and preventing odor breeding, and can be applied in scenes such as air conditioners, fresh air, air purifiers and cars.

[0050] The sterilization module has a normal mode and an intelligent mode. The normal mode is to switch between at least two powers and the running time at each power is fixed. For example, the normal mode is provided with high power and low power, the input power corresponding to the high power is 1.8W and the input current is 150mA, the input power corresponding to the low power is 1W and the input current is 80mA, after the user starts the sterilization module and runs in the normal mode, the sterilization module first runs at high power for t1 time, then switches to low power for t2 time, then switches to high power for t1 time, and then switches to low power for t2 time, and so on, t1 ranges from 1 to 5 hours, and t2 ranges from 12 to 72 hours. In the intelligent mode, the sterilization module switches between at least two powers and controls the running time at each power according to the indoor environment temperature and the indoor relative humidity.

[0051] Referring to Figure 2 An embodiment of the structure of the device of the application is shown. The control device of the air conditioner can include an acquisition unit 102 and a control unit 104.

[0052] The acquisition unit 102 is configured to acquire the indoor environment temperature and the indoor relative humidity after the sterilization module starts running in the intelligent mode. The specific functions and processes of the acquisition unit 102 are described in step S110. Temperature sensors and humidity sensors can be provided for real-time sampling, and filtering algorithms can be used to eliminate interference and temperature compensation can be used to correct humidity measurement errors.

[0053] The control unit 104 is configured to determine the bacterial breeding risk level of the indoor environment according to the indoor environment temperature and the indoor relative humidity. The specific functions and processes of the control unit 104 are described in step S120.

[0054] The bacterial breeding speed is closely related to the environment temperature and humidity. In a high-temperature and high-humidity environment, the bacterial metabolism is active and the reproduction speed is fast; in a low-temperature and low-humidity environment, the bacterial activity is significantly inhibited and the reproduction speed is reduced. Therefore, the bacterial breeding risk level is divided into three risk levels: high risk, medium risk and low risk, so that the system can adjust the sterilization strategy accordingly, and the sterilization in a high-risk environment is strengthened and the energy consumption in a low-risk environment is reduced.

[0055] In some embodiments, the control unit 104 determines the indoor bacterial breeding risk level according to the indoor environment temperature and the indoor relative humidity, including: judging the size of the indoor environment temperature and the size of the indoor relative humidity; if the indoor environment temperature is greater than or equal to a preset first temperature, and the indoor relative humidity is greater than a preset first humidity, determining that the bacterial breeding risk level is high risk; if the indoor environment temperature is less than or equal to a preset second temperature and greater than or equal to a preset third temperature, and the indoor relative humidity is less than a preset second humidity, determining that the bacterial breeding risk level is low risk; if the indoor environment temperature is less than the preset third temperature, determining that the bacterial breeding risk level is low risk; and the bacterial breeding risk level corresponding to the combination of the indoor environment temperature and the indoor relative humidity in other cases is medium risk, except for the high risk and the low risk; wherein the preset first temperature > the preset second temperature > the preset third temperature, and the preset first humidity > the preset second humidity.

[0056] The high risk refers to easy breeding of bacteria, the low risk refers to not easy breeding of bacteria, and the medium risk refers to general bacterial breeding. When the indoor environment is a high-temperature and high-humidity environment and a normal-temperature and high-humidity environment, it is considered that bacteria are easy to breed, the high-temperature and high-humidity environment corresponds to a temperature and humidity range of indoor temperature ≥ 30°C and indoor relative humidity ≥ 80%, and the normal-temperature and high-humidity environment corresponds to a temperature and humidity range of 23°C ≤ indoor temperature ≤ 30°C and indoor relative humidity ≥ 80%. Therefore, the preset first temperature can be set to 23°C, the preset first humidity can be set to 80%, and when 23°C ≤ indoor temperature and indoor relative humidity ≥ 80%, the indoor environment is a high-temperature and high-humidity environment or a normal-temperature and high-humidity environment, at this time, the system determines that the bacterial breeding risk level is high risk, and the sterilization efficiency needs to be enhanced to avoid the increase of the number of bacteria.

[0057] When the indoor environment is a low-temperature and medium-humidity environment or an extremely low-temperature environment, it is considered that bacteria are not easy to breed, the low-temperature and medium-humidity environment corresponds to a temperature and humidity range of 5°C ≤ indoor temperature ≤ 15°C and indoor relative humidity < 50%, and the extremely low-temperature environment corresponds to a temperature range of indoor temperature ≤ 5°C. Therefore, the preset second temperature can be set to 15°C, the preset second humidity can be set to 50%, and the preset third temperature can be set to 5°C, when 5°C ≤ indoor temperature ≤ 15°C and indoor relative humidity < 50%, the indoor environment is a low-temperature and medium-humidity environment, and when indoor temperature ≤ 5°C, the indoor environment is an extremely low-temperature environment, at this time, the system determines that the bacterial breeding risk level is low risk, and the sterilization module can play a sterilization effect at low power, and the running time of the sterilization module at high power can be reduced to reduce energy consumption.

[0058] The bacterial growth risk level corresponding to temperature and humidity ranges outside the high-risk and low-risk ranges is medium risk, such as when 5 ≤ indoor temperature ≤ 15°C and indoor relative humidity ≥ 50%, or indoor temperature ≥ 23°C and indoor relative humidity < 80%, or 15°C ≤ indoor temperature ≤ 23°C. In these cases, compared to high-risk sterilization modules, the operating time at high power is appropriately reduced and the operating time at low power is increased to achieve a balance between sterilization effectiveness and energy conservation.

[0059] In some embodiments, more bacterial growth risk levels can be divided based on high risk, medium risk, and low risk. Each risk level corresponds to a different operating time, and the high-power operating time under higher bacterial growth risk is greater than the high-power operating time under lower bacterial growth risk, and the low-power operating time under higher bacterial growth risk is less than the low-power operating time under lower bacterial growth risk. That is, the operating time is set in a stepped manner to match the sterilization effect with the current environment.

[0060] In some embodiments, additional preset powers can be set in addition to high and low power. For the same bacterial growth risk level, the sterilization module's operating time at higher power is shorter than its operating time at lower power. Specifically, the sterilization module's operating time at different preset powers can be set in a stepped manner to match sterilization efficiency with the current environment. Since bacteria growth takes time, cycling between high and low power ensures sterilization while reducing power consumption.

[0061] The control unit 104 is further configured to control the sterilization module to switch between at least two preset power levels and to control the duration of operation of the sterilization module at the at least two preset power levels according to the bacterial growth risk level. The specific functions and processing of the control unit 104 are described in step S130.

[0062] There are at least two preset power levels: high and low. High power delivers a high sterilization intensity, quickly killing most bacteria. Low power reduces energy consumption and prevents bacterial growth. In intelligent mode, the sterilization module's operating time at each power level is controlled based on indoor temperature and humidity. Risk levels are reassessed and parameters adjusted after each cycle, improving sterilization efficiency while reducing energy consumption.

[0063] In some embodiments, the at least two preset powers include a preset first power and a preset second power; the preset first power > the preset second power, that is, the preset first power is a high power and the preset second power is a low power. The control unit 104 controls the running time length of the sterilization module at the at least two preset powers according to the bacterial breeding risk level, including: in the case that the bacterial breeding risk level is high risk, controlling the sterilization module to run at the preset first power for a first time length, and then switching to the preset second power for a second time length; in the case that the bacterial breeding risk level is medium risk, controlling the sterilization module to run at the preset first power for a third time length, and then switching to the preset second power for a fourth time length; in the case that the bacterial breeding risk level is low risk, controlling the sterilization module to run at the preset first power for a fifth time length, and then switching to the preset second power for a sixth time length; wherein the first time length > the third time length > the fifth time length, the second time length > the fourth time length > the sixth time length, the first time length < the second time length, the third time length < the fourth time length, and the fifth time length < the sixth time length.

[0064] When running at a high power, the sterilization module has stronger sterilization capability and can quickly kill bacteria in the air or on the surface of an object; however, the energy consumption is higher and additional effects may be generated under a high power state. When running at a low power, the sterilization capability is weaker, but the energy consumption is lower and the safety is higher, which is suitable for maintaining the sterilization effect for a long time. Under the same risk level, a balance needs to be found between quickly suppressing bacteria and continuously controlling and saving costs, that is, a short time of high power is used to quickly reduce the number of bacteria, and then a long time of low power is used to maintain the sterilization effect, which ensures the efficiency and avoids the disadvantages of long-term high-power running. Therefore, under the same risk level, the running time length of the high power < the running time length of the low power, that is, the first time length < the second time length, the third time length < the fourth time length, and the fifth time length < the sixth time length.

[0065] The bacterial breeding risk level being high risk means that the current environment is very suitable for the rapid reproduction of bacteria, and there may be a large number of bacteria present and continuously breeding; under medium risk, the environment is suitable for the slow reproduction of bacteria, and the number of bacteria is moderate; under low risk, the environment is not conducive to the growth of bacteria, and the number of bacteria is small and the reproduction is slow. The corresponding sterilization strategy needs to match the risk level: the higher the risk, the more it needs to be forcefully suppressed; the lower the risk, the more it focuses on moderate maintenance. Therefore, a longer time of high-power sterilization is needed to quickly control the situation under high risk, and the maintenance time of low power can be relatively shortened, that is, the first time length > the third time length > the fifth time length, and the second time length > the fourth time length > the sixth time length. The first time length can be set to 5h, the second time length can be set to 12h, the third time length can be set to 3h, the fourth time length can be set to 48h, the fifth time length can be set to 1h, and the sixth time length can be set to 72h.

[0066] In the high risk of bacterial growth, the sterilization module is operated at high power for 5 hours and at low power for 12 hours, and the operation is repeated; in the medium risk of bacterial growth, the sterilization module is operated at high power for 3 hours and at low power for 48 hours, and the operation is repeated; in the low risk of bacterial growth, the sterilization module is operated at high power for 1 hour and at low power for 72 hours, and the operation is repeated. That is, in the environment where bacteria are easy to grow, the running time of high power is prolonged and the running time of low power is reduced, and in the environment where bacteria are not easy to grow, the running time of high power is reduced and the running time of low power is prolonged. Thus, the sterilization effect in different environments is ensured, the energy consumption is significantly reduced, the equipment life is prolonged, the full-automatic adaptation is realized, and the user experience is improved.

[0067] In some embodiments, the control unit 104 is further configured to control the running proportion of the sterilization module at the at least two preset powers according to the bacterial growth risk level of the indoor environment after determining the bacterial growth risk level; and the running period of the sterilization module is a fixed time length.

[0068] Specifically, if the sterilization module has a fixed total time length as a running period, the sterilization efficiency can be adjusted by controlling the running time proportion of the sterilization module at each power. Such control can avoid the sterilization interval disorder caused by the non-fixed running period, and the sterilization effect is more stable and the energy consumption is more controllable.

[0069] In some embodiments, the control unit 104 controls the running proportion of the sterilization module at the at least two preset powers according to the bacterial growth risk level, including: in the case that the bacterial growth risk level is high risk, controlling the sterilization module to run at a preset first power with a first time length proportion and to run at a preset second power with a second time length proportion; in the case that the bacterial growth risk level is medium risk, controlling the sterilization module to run at the preset first power with a third time length proportion and to run at the preset second power with a fourth time length proportion; in the case that the bacterial growth risk level is low risk, controlling the sterilization module to run at the preset first power with a fifth time length proportion and to run at the preset second power with a sixth time length proportion; wherein the first time length proportion > the third time length proportion > the fifth time length proportion, and the second time length proportion < the fourth time length proportion < the sixth time length proportion.

[0070] In a high-risk environment, bacteria multiply at a very fast speed and can breed in large quantities in a short time, at which time a higher proportion of high-power operation is needed to quickly reduce the bacterial base by using the strong sterilization capacity to avoid bacterial flooding. The main role of low power is to maintain the sterilization effect. When the bacteria are greatly suppressed by high power in a high-risk environment, long-term low-power operation is not needed to prevent rebound. Conversely, in a low-risk environment, bacteria multiply slowly, and the proportion of high power only needs to be maintained at a low level to control the number of bacteria, and the proportion of low power can be increased to save energy to the maximum extent while ensuring the effect and achieve the balance of sterilization on demand. Therefore, the first time length proportion > the third time length proportion > the fifth time length proportion, and the second time length proportion < the fourth time length proportion < the sixth time length proportion. For example, the running cycle of the sterilization module is 24h, in a high-risk environment, the sterilization module first runs at high power for 7.2h (30% of the proportion), and then runs at low power for 16.8h (70% of the proportion), and so on. In a medium-risk environment, the sterilization module first runs at high power for 4.8h (20% of the proportion), and then runs at low power for 19.2h (80% of the proportion), and so on. In a low-risk environment, the sterilization module first runs at high power for 1.2h (5% of the proportion), and then runs at low power for 22.8h (95% of the proportion), and so on. Thus, the proportion of high power is high in a high-risk environment, ensuring fast sterilization; the proportion of low power is high in a low-risk environment, avoiding energy waste, and achieving the precise balance of sterilization effect and energy consumption.
