The specific meaning of the above terms in the present application can be understood by those skilled in the art as the case may be.
Because the disinfection liquid is usually used to disinfect the surface of an object at present, or a disinfection machine is used to disinfect air after people leave the field, or only indoor air is circularly collected to disinfect and purify in the machine, the method has great limitation, and the air can not be disinfected, prevented and controlled in real time. Therefore, the sterilizing unit is arranged in the air duct of the wall-mounted air conditioner, and the operation of the sterilizing unit is controlled in real time according to the number of bacterial colonies in the air, so that better sterilizing and disinfecting effects can be achieved.
In this application, wall-hanging air conditioner has air intake and air outlet, and the air of interior space returns to the interior space via the air outlet in entering into wall-hanging air conditioner via the air intake, handled the back again. Be formed with the wind channel between air intake and the air outlet, wall-hanging air conditioner disposes the degerming unit, and this degerming unit sets up in the wind channel, just so can carry out degerming, disinfection treatment through the degerming unit to all air in the wind channel of flowing through. This degerming unit includes anion bacteria removing device, ultraviolet bacteria removing device, plasma bacteria removing device, degerming liquid bacteria removing device, can disinfect the processing to the air through these bacteria removing device, gets rid of bacterium, the virus in the air. It should be noted that these degerming devices may be operated simultaneously or only partially.
In this application, anion bacteria removing device, ultraviolet bacteria removing device, plasma bacteria removing device, degerming liquid bacteria removing device's degerming efficiency increases in proper order. That is, in the same time, the number of bacteria and viruses that can be sterilized by the negative ion sterilization apparatus is the smallest, and the number of bacteria and viruses that can be sterilized by the bacteria-removing liquid sterilization apparatus is the largest.
It should be noted that the sterilization unit may also include only any two or three of the negative ion sterilization device, the ultraviolet sterilization device, the plasma sterilization device, and the sterilization liquid sterilization device, and on the premise of not deviating from the principle of the present application, a person skilled in the art may flexibly select a specific configuration manner of the sterilization unit according to a specific application scenario as long as a better sterilization effect can be obtained.
In one possible embodiment, the negative ion sterilization device is disposed in an air duct of a wall-mounted air conditioner. When the anion sterilization device operates, a large amount of air anions can be generated, and the air anions can be used for sterilizing and treating the air to remove bacteria, viruses and the like in the air, so that the anion sterilization device has a good sterilization effect. Obviously, the anion sterilization device can also be arranged at the air inlet or the air outlet of the wall-mounted air conditioner.
It should be noted that, the negative ion sterilization apparatus is generally configured to be able to process an input dc or ac power through an EMI processing circuit and a lightning protection circuit, increase the voltage to an ac high voltage through a pulse circuit, an overvoltage current limiting circuit, a high-low voltage isolation circuit, etc., then obtain a pure dc negative high voltage through rectification and filtering of a special grade electronic material, connect the dc negative high voltage to a release tip made of metal or carbon element, generate a high corona by using the dc high voltage at the tip, emit a large amount of electrons at a high speed, and the electrons cannot exist in the air for a long time and are immediately captured by oxygen molecules in the air, thereby generating air negative ions. Obviously, the negative ion odor removing device can be arranged in other ways, and those skilled in the art can flexibly select the specific arrangement way of the negative ion odor removing device according to the specific application scenario as long as the negative ion can be generated.
In one possible embodiment, the uv sterilization device is disposed inside an outlet vent of a wall-mounted air conditioner. When the ultraviolet sterilization device is operated, ultraviolet rays can be emitted, and the ultraviolet rays can remove bacteria and viruses in an irradiation area and air flowing through the irradiation area. However, only sufficient irradiation time can achieve a good sterilization effect. Obviously, the ultraviolet sterilization device can also be arranged at the air inlet of the wall-mounted air conditioner or in the air duct.
The uv sterilization apparatus generally includes an uv lamp, which may be, but is not limited to, a high uv high pressure mercury lamp, a high strength metal halide lamp, a plate burning lamp, a capillary ultra high pressure mercury lamp, a light cleaning lamp, a short arc hernia lamp, and the like.
In one possible embodiment, the plasma sterilization apparatus is disposed within a duct of a wall-mounted air conditioner. When the plasma sterilization device is operated, air can be ionized to generate plasma, and the plasma can generate atoms or molecules in ground state or excited state besides negative ions and positive ions, and can be summarized as short-life active particles (such as O, OH, HO)2Etc.) and long-lived active ions (e.g., excited state N)2、H2O2Etc.). The plasma can remove bacteria and viruses in the air through the penetration effect of high-speed ions, the electric field effect and the action of high-energy ions and active free radicals, wherein the penetration effect means that the shearing force generated on the surfaces of the bacteria and the viruses by the plasma is greater than the surface tension of cell membranes of the bacteria and the viruses, the electric field effect means that the cell membranes of the bacteria and the viruses can be punctured when the average electric field strength exceeds a certain strength, and the high-energy ions and the active free radicals can react with proteins and nucleic acids of the bacteria and the viruses. Therefore, bacteria and viruses in the air flowing through the air channel can be effectively removed through the plasma, and the plasma can enter the indoor space along with the air to further remove the bacteria and viruses in the indoor space, so that a good bacteria removing effect is obtained. Obviously, the plasma sterilization device can also be arranged at the air inlet or the air outlet of the wall-mounted air conditioner.
The plasma sterilization apparatus generally includes a positive electrode and a negative electrode, and when the plasma sterilization apparatus is energized, an electrostatic field is formed between the positive electrode and the negative electrode, and when air passes through the electrostatic field, the air collides with the electrostatic field and is dissociated to generate the plasma. Without departing from the principle of the present application, a person skilled in the art can flexibly select a specific arrangement form of the plasma sterilization apparatus according to a specific application scenario, as long as the plasma can be generated and the air can be sterilized by the plasma.
In one possible embodiment, the bacteria removing liquid sterilizing device is disposed inside an air outlet of the wall-mounted air conditioner, and the bacteria removing liquid sterilizing device sterilizes the air by spraying bacteria removing liquid into the air. Obviously, the degerming liquid bacteria removing device can also be arranged in an air inlet or an air duct of the wall-mounted air conditioner, and under the condition, the condition that a liquid receiving disc used for collecting the dripped degerming liquid is arranged below the degerming liquid bacteria removing device can be considered, so that the bacteria liquid is prevented from dripping into the wall-mounted air conditioner.
It should be noted that the bacteria removing liquid bacteria removing device may include a liquid storage tank for storing bacteria removing liquid, a booster pump, a nozzle, and a liquid transport tube connecting the nozzle and the liquid storage tank, and the nozzle is aligned with the inner side of the air outlet of the wall-mounted air conditioner. When the bacteria removing liquid sterilizing device operates, under the action of the booster pump, the bacteria removing liquid in the liquid storage tank reaches the spray head through the liquid conveying pipe and is sprayed out through the spray head, and the air flowing through the air outlet is sterilized, so that the purposes of sterilizing and disinfecting are achieved. Obviously, the bacteria removing device may be arranged in other manners, for example, high-pressure air (such as compressed air) passes through a liquid storage tank storing the bacteria removing liquid, the high-pressure air coming out from the liquid storage tank carries the bacteria removing liquid, and the air is sent into the air duct, so that the air passing through the air duct can be sterilized. Without departing from the principle of the present application, a person skilled in the art can flexibly select a specific setting form of the bacteria-removing liquid sterilization device according to a specific application scenario, as long as the air can be sterilized by the bacteria-removing liquid.
It should be noted that the spraying angle of the spray head can be flexibly selected, for example, when the bacteria-removing liquid sterilizer operates, the spray head rotates along the air flowing direction, and when the bacteria-removing liquid sterilizer operates, the spray head sprays along the length direction of the air outlet of the wall-mounted air conditioner, and so on. On the premise of not deviating from the principle of the application, a person skilled in the art can flexibly select the air sterilizing liquid according to a specific application scene as long as the air sterilizing liquid sprayed by the spray head can sterilize the air.
The sterilization liquid may be, but is not limited to, a chlorine-containing disinfectant, a peroxide disinfectant, an ethylene oxide disinfectant, an alcohol disinfectant, a biguanide disinfectant, a quaternary ammonium salt disinfectant, or the like.
In this application, wall-hanging air conditioner includes gaseous detection module, and this gaseous detection module is set to the bacterial colony quantity that can detect in the air.
It should be noted that, the gas detection module may be disposed at an air inlet of a wall-mounted air conditioner, or at an air outlet, or in an air duct, or may be disposed at an outer side of a housing of the wall-mounted air conditioner, or at a position close to the wall-mounted air conditioner, and the specific disposition position of the gas detection module is not limited in this application.
It should be noted that the gas detection module may be a biosensor, and the biosensor is an instrument that is sensitive to a biological substance and converts the concentration of the biological substance into an electrical signal for detection, and the gas detection module may be classified into: enzyme sensors, fungal sensors, cell sensors, tissue sensors and immunosensors. Obviously, the gas detection module can also be a laser colony measuring instrument, and the colony group quantity in the air is detected by the laser colony measuring instrument, namely, the colony group quantity in the air is expressed. Of course, the gas detection module can also be a PM2.5 sensor, since bacteria and viruses usually cannot enter a free state by themselves and usually need to be carried or adsorbed on a carrier for transmission, and particulate matters in the air are usually the best carriers for the bacteria and the viruses. Therefore, the content of the PM2.5 in the air of the indoor space can be detected in real time through the PM2.5 sensor, and the colony number in the air of the indoor space is reflected by the content of the PM 2.5. Without deviating from the principles of the present application, one skilled in the art can flexibly select the specific form of the gas detection module according to the specific application scenario, as long as it can accurately detect the number of bacterial colonies in the air.
In this application, wall-hanging air conditioner includes the degerming liquid measurement module, and this degerming liquid measurement module is set to the surplus that can detect the degerming liquid among the degerming liquid bacteria removing device.
It should be noted that the sterilization liquid measuring module may be a liquid level meter or a weight sensor. That is, the residual amount of the sterilization liquid detected by the sterilization liquid measuring module can be represented by the liquid level height of the sterilization liquid, and can also be represented by the weight of the sterilization liquid. Wherein, the level meter can be but not limited to a tuning fork vibration type level meter, a magnetic suspension type level meter, a pressure type level meter, an ultrasonic level meter, a sonar wave level meter, a magnetic turning plate level meter, a radar level meter and the like. The weight sensor may be, but is not limited to, a strain gauge load cell, an opto-electronic load cell, or a capacitive load cell, among others. Obviously, the sterilization liquid measuring module can be set in other forms, and those skilled in the art can flexibly select the module according to a specific application scenario, as long as the residual amount of the sterilization liquid in the sterilization liquid sterilization device is obtained through the sterilization liquid measuring module.
In order to realize all functions of the following sterilization control method, in the present application, the wall-mounted air conditioner is further provided with a control module, and the control module is respectively connected with the negative ion sterilization device, the ultraviolet sterilization device, the plasma sterilization device, the sterilization liquid sterilization device, the gas detection module and the sterilization liquid measurement module, and can control the operation or non-operation of the negative ion sterilization device, the ultraviolet sterilization device, the plasma sterilization device and the sterilization liquid sterilization device based on the oxygen concentration value detected by the gas detection module or based on the residual amount of the sterilization liquid detected by the sterilization liquid measurement module. It should be noted that, such a control module may be physically a control chip of the wall-mounted air conditioner itself, may be a controller specially used for executing the method of the present application, or may be a functional module or a functional unit of a general controller.
Next, a possible implementation of the sterilization control method of the wall-mounted air conditioner of the present invention will be described with reference to fig. 1 to 3.
In one possible embodiment, as shown in fig. 1, the sterilization control method of the present invention comprises:
s100: when a wall-mounted air conditioner runs, acquiring the number of first bacterial colonies in the air;
s101: judging whether the number of the first colonies is larger than or equal to a first threshold value, if so, executing S102; if not, executing S103;
s102: controlling the operation of the degerming unit;
s103: the sterilization unit is not controlled to operate.
In S100, when the wall-mounted air conditioner runs, the number of first bacterial colonies in the air is acquired through the gas detection module.
In S101, based on the first colony number obtained in S100, it is determined whether the first colony number is greater than or equal to a first threshold, and if the first colony number is greater than or equal to the first threshold, for example, the first colony number is 1800CFU/m3The first threshold value is 1500CFU/m3. When the number of bacteria and viruses in the air is large, the operation of the sterilization unit is controlled, i.e., S102 is performed. The sterilization unit is used for sterilizing the air, so that the number of bacteria and viruses in the indoor space can be reduced, and better sterilization and disinfection effects can be achieved.
If the number of first colonies is less than the first threshold, for example, the number of first colonies is 500CFU/m3The first threshold value is 1500CFU/m3. In this case, it is explained that the number of bacteria and viruses in the air is relatively small, and the sterilization process may not be performed, and in this case, the operation of the sterilization unit is not controlled, that is, S103 is performed. Therefore, the operation frequency of the degerming unit can be reduced, and the service life of the degerming unit is prolonged.
It should be noted that CFU means the number of colonies forming colonies, for example, two identical bacteria are close to each other or attached to each other, and thus two bacteria will form a colony after being cultured, which is 2 bacteria, 1 CFU.
It should be noted that when the first colony count is smaller than the first threshold, the sterilization unit may also be controlled to operate for a preset time period every preset time period, for example, the sterilization unit may be controlled to operate for 30 minutes every two hours. Without departing from the principle of the present application, a person skilled in the art can flexibly select a specific mode for controlling the operation of the sterilization unit according to a specific application scenario, as long as a better sterilization and disinfection effect can be obtained.
Through the control mode, the operation of the degerming unit can be controlled or not controlled according to the number of the first bacterial colonies in the air in real time, so that bacteria and viruses in the air can be better removed, the number of the bacteria and the viruses in the air is controlled within a reasonable range, and better degerming and disinfection effects are obtained. Meanwhile, the operation frequency of the degerming unit can be reduced, and the service life of the degerming unit is prolonged.
In one possible embodiment, controlling the operation of the degerming unit specifically comprises: based on the first colony quantity, one or more operations in the negative ion sterilization device, the ultraviolet sterilization device, the plasma sterilization device and the bacteria removing liquid sterilization device are controlled. Through the control mode, air can be sterilized through one or more of the negative ion sterilization device, the ultraviolet sterilization device, the plasma sterilization device and the sterilization liquid sterilization device, and good sterilization and disinfection effects are achieved.
Referring now to FIG. 2, one possible implementation of the present application for controlling one or more operations of the negative ion sterilization apparatus, the ultraviolet sterilization apparatus, the plasma sterilization apparatus, and the bacteria-removing liquid sterilization apparatus based on the first colony count is illustrated.
In one possible embodiment, as shown in fig. 2, the sterilization control method of the present invention further comprises:
s200: obtaining a first colony number in the air;
s201: judging whether the number of the first colonies is larger than or equal to a first threshold value, if so, executing S203; if not, executing S202;
s202: the operation of the degerming unit is not controlled;
s203: further judging whether the number of the first colonies is greater than or equal to a second threshold value, if so, executing S205; if not, executing S204;
s204: controlling the negative ion sterilization device to operate;
s205: further judging whether the number of the first colonies is larger than or equal to a third threshold value, if so, executing S207; if not, executing S206;
s206: controlling the operation of the ultraviolet sterilization device;
s207: further judging whether the number of the first colonies is greater than or equal to a fourth threshold, if so, executing S209; if not, executing S208;
s208: controlling the operation of the plasma sterilization device;
s209: further judging whether the number of the first colonies is greater than or equal to a fifth threshold value, if so, executing S211; if not, executing S210;
s210: controlling the operation of the bacteria removing liquid and bacteria removing device;
s211: and controlling the negative ion sterilization device, the ultraviolet sterilization device, the plasma sterilization device and the bacteria removing liquid sterilization device to operate simultaneously.
In S200, similarly to S100, the first colony count in the air is acquired by the above-described gas detection module.
In S201, based on the first colony number obtained in S200, it is determined whether the first colony number is greater than or equal to a first threshold, and if the first colony number is less than the first threshold, for example, the first colony number is 500CFU/m3The first threshold is 1500CFU/m3. If the number of bacteria and viruses in the air is small, the sterilization unit is not controlled to operate, i.e., S202 is performed.
If the number of the first colonies is greater than or equal to the first threshold, which indicates that the number of bacteria and viruses in the air is large, then it is further determined whether the number of the first colonies is greater than or equal to the second threshold, and S203 is executed.
If the first colony number is less than the second threshold value, i.e., the first colony number is greater than or equal to the first threshold value and less than the second threshold value, for example, the first colony number is 1800CFU/m3The first threshold value is 1500CFU/m3The second threshold is 2000CFU/m3. At this time, the operation of the negative ion sterilization device with the lowest sterilization efficiency is controlled, namely S204 is executed, and air is sterilized through air negative ions generated by the negative ion sterilization device, so that the current sterilization and disinfection requirements can be met.
If the first colony number is greater than or equal to the second threshold, then it is further determined whether the first colony number is greater than or equal to a third threshold, and S205 is executed.
If the number of the first colonies is less than the third threshold value, i.e., the number of the first colonies is equal to or greater than the second threshold value and less than the third threshold value, for example, the number of the first colonies is 2200CFU/m3The second threshold is 2000CFU/m3And the third threshold is 2500CFU/m3. At this time, the operation of the ultraviolet sterilization apparatus with a slightly high sterilization efficiency is controlled, that is, S206 is executed, and the bacteria and viruses in the air are transmitted by the ultraviolet sterilization apparatusThe radiated ultraviolet rays sterilize the air to meet the current sterilization and disinfection requirements.
If the first colony number is greater than or equal to the third threshold, then it is further determined whether the first colony number is greater than or equal to the fourth threshold, and S207 is executed.
If the first colony number is less than the fourth threshold value, i.e., the first colony number is greater than or equal to the third threshold value and less than the fourth threshold value, for example, the first colony number is 2800CFU/m3And the third threshold is 2500CFU/m3And the fourth threshold value is 3000CFU/m3. At this time, the operation of the plasma sterilization device with relatively high sterilization efficiency is controlled, that is, S208 is executed, and the air is sterilized by the plasma generated by the plasma sterilization device, so as to meet the current sterilization and disinfection requirements.
If the first colony number is greater than or equal to the fourth threshold, then it is further determined whether the first colony number is greater than or equal to the fifth threshold, and S209 is executed.
If the number of the first colonies is less than the fifth threshold, i.e., the number of the first colonies is equal to or greater than the fourth threshold and less than the fifth threshold, for example, the number of the first colonies is 3300CFU/m3And the fourth threshold value is 3000CFU/m3The fifth threshold is 3500CFU/m3. At this time, the operation of the bacteria-removing liquid sterilizing device with relatively high sterilizing efficiency is controlled, that is, S210 is executed, and the bacteria-removing liquid sterilizing device sprays the bacteria-removing liquid into the air to achieve the purpose of sterilization and disinfection.
If the first colony number is larger than the fifth threshold, it indicates that the number of bacteria and viruses in the air is very large, and at this time, the negative ion sterilization device, the ultraviolet sterilization device, the plasma sterilization device, and the bacteria-removing liquid sterilization device are controlled to operate simultaneously, that is, S211 is executed. By means of the simultaneous operation of the four degerming devices, bacteria and viruses in the air can be removed as soon as possible, and better degerming and disinfection effects are achieved.
Through the control mode, one or four of anion bacteria removing device, ultraviolet bacteria removing device, plasma bacteria removing device, degerming liquid bacteria removing device can be controlled based on the concrete numerical value of first bacterial colony quantity to the operation simultaneously, thereby can be when guaranteeing degerming, disinfection effect, reduce each bacteria removing device's operation frequency, prolong each bacteria removing device's life.
When the number of the first bacterial colonies is greater than or equal to the first threshold and smaller than the second threshold, controlling any one of the negative ion sterilization device, the ultraviolet sterilization device, the plasma sterilization device and the bacteria-removing liquid sterilization device to operate; when the number of the first bacterial colonies is larger than or equal to a second threshold value and smaller than a third threshold value, controlling any two of the four degerming devices to operate; when the number of the first bacterial colonies is larger than or equal to a third threshold value and smaller than a fourth threshold value, controlling any three sterilizing devices in the four sterilizing devices to operate; and when the number of the first colonies is larger than or equal to a fourth threshold value, controlling the four degerming devices to operate simultaneously. Obviously, the operation of the negative ion sterilization device and the ultraviolet sterilization device may also be controlled when the first colony number is greater than or equal to the first threshold value and is less than the third threshold value; and when the number of the first colonies is larger than or equal to the third threshold and smaller than the fourth threshold, controlling the plasma sterilization device and the bacteria-removing liquid sterilization device to operate, and the like. One skilled in the art can flexibly control one or more of the above four sterilization devices based on the size of the first colony count, as long as the air can be sterilized. However, these control methods have problems such as excessive sterilization and disinfection when the number of first colonies is low, poor sterilization and disinfection effects when the number of first colonies is high, and high frequency of use of each sterilization apparatus.
In one possible embodiment, as shown in fig. 3, the sterilization control method of the present invention further comprises:
s300: after the operation of the bacteria-removing liquid sterilizing device is controlled, the residual amount of the bacteria-removing liquid in the bacteria-removing liquid sterilizing device is obtained;
s301: judging whether the residual amount of the sterilization liquid is larger than a preset amount, if so, executing S302; if not, executing S303;
s302: continuously controlling the operation of the bacteria removing liquid and bacteria removing device;
s303: controlling the bacteria removing liquid sterilizing device to stop running;
s304: after the operation of the bacteria removing liquid sterilization device is controlled to stop, the second bacterial colony quantity in the air is obtained again;
s305: and further controlling one or more of the negative ion sterilization device, the ultraviolet sterilization device and the plasma sterilization device to operate based on the second colony number.
In S300, after the operation of the sterilization liquid removing apparatus is controlled, that is, after S210 or S211 is executed, the amount of the sterilization liquid in the sterilization liquid removing apparatus is gradually decreased, and at this time, the residual amount of the sterilization liquid in the sterilization liquid removing apparatus is obtained through the sterilization liquid measuring module.
In S301, based on the remaining amount of the sterilization liquid obtained in S300, it is determined whether the remaining amount of the sterilization liquid is greater than a preset amount, and if the remaining amount of the sterilization liquid is greater than the preset amount, it indicates that sufficient sterilization liquid is stored in the sterilization apparatus, and at this time, the operation of the sterilization apparatus is continuously controlled, that is, S302 is executed, and the sterilization and disinfection effects of the sterilization unit are ensured by the sterilization liquid sterilization apparatus.
If the residual amount of the sterilization liquid is less than or equal to the preset amount, it is indicated that the sterilization liquid in the sterilization liquid sterilization device is less at the moment, and the residual amount of the sterilization liquid cannot meet the requirements for sterilization and disinfection, so that the situation that no sterilization liquid is available exists in the operation process of the sterilization liquid sterilization device is avoided, at the moment, the sterilization liquid sterilization device is controlled to stop operating, and S303 is executed.
It should be noted that the preset amount is the amount of the bacteria removing liquid consumed by the bacteria removing liquid sterilizing device continuously operating for a period of time, and a person skilled in the art can flexibly determine a specific value of the period of time according to experience, experiments, calculation and other manners. For example, if the time period is one hour, the preset amount is the amount of the bacteria removing liquid consumed by the bacteria removing liquid sterilizing apparatus continuously operating for one hour. It should be noted here that if the amount of the sterilizing liquid that can be sprayed by the sterilizing liquid removing device per unit time is a fixed value, that is, the unit spraying amount is a fixed value, the amount of the sterilizing liquid consumed by the sterilizing liquid removing device for continuously operating the sterilizing liquid removing device for one hour at the unit spraying amount is taken as the preset amount. If the degerming liquid amount that can spray in the degerming liquid bacteria removing device unit time can be adjusted, that is, the unit spraying amount can be adjusted, then with degerming liquid bacteria removing device with the degerming liquid amount that this degerming liquid bacteria removing device biggest unit spraying amount continued to operate the consumed degerming liquid amount of an hour as the preset amount. On the premise of not deviating from the principle of the application, a person skilled in the art can flexibly determine a specific value of the preset amount according to a specific application scene as long as the stable operation of the sterilizing liquid sterilizing device can be ensured.
When the residual amount of the sterilization liquid is less than or equal to the preset amount, the operation of the sterilization liquid removing device may be continuously controlled without controlling the sterilization liquid removing device to stop operating. However, this control method has a problem that air cannot be sterilized after the sterilizing liquid is consumed.
After the operation of the sterilization liquid removing apparatus is controlled to stop, the second colony number in the air is obtained again through the gas detection module, that is, S304 is executed.
It should be noted that the second colony content in the air may be acquired again while the operation of the bacteria-removing liquid sterilizing apparatus is controlled to stop, that is, S304 may be executed while S303 is executed. The skilled person in the art can flexibly select a specific time for obtaining the second bacterial colony content in the air again according to a specific application scenario, as long as the second bacterial colony content in the air can be accurately obtained.
In S305, based on the second bacterial colony quantity that obtains in S304, selectively control one or more operations in negative ion bacteria removing device, ultraviolet bacteria removing device, the plasma bacteria removing device, just so can control one or more operations in these three bacteria removing device according to the size of second bacterial colony quantity to can ensure degerming, the disinfection effect of degerming unit better, promote user experience.
Note that the control of negative ion sterilization based on the second colony countThe specific control mode of the device, the ultraviolet sterilization device and the plasma sterilization device can refer to the control mode of controlling the operation of the negative ion sterilization device, the ultraviolet sterilization device, the plasma sterilization device and the bacteria-removing liquid sterilization device based on the number of the first bacterial colonies. For example, when the number of second colonies is less than the first threshold, e.g., the number of second colonies is 600CFU/m3When the second colony number is greater than or equal to the second threshold value and less than the third threshold value, for example, the second colony number is 2600CFU/m3In time, the operation of the plasma sterilization device can be controlled. If the number of the second colonies is equal to or greater than the fourth threshold value and less than the fifth threshold value, for example, the number of the second colonies is 3300CFU/m3In this case, the negative ion sterilization device, the ultraviolet sterilization device, and the plasma sterilization device may be controlled to operate simultaneously, and so on.
Through the control mode, the sterilization and disinfection effects can be ensured while the stable and efficient operation of the sterilization liquid sterilization device is ensured.
After the sterilization liquid removing device is controlled to stop operating, the air may be sterilized by controlling the negative ion removing device, the ultraviolet removing device, and the plasma removing device to operate simultaneously, or by controlling the plasma removing device with high sterilizing efficiency to operate, instead of re-acquiring the second colony content in the air, that is, after S303 is executed, S304 and S305 are not executed. However, these control methods have problems that the sterilization and disinfection are excessive when the number of the second colonies is low, and the sterilization and disinfection effects are poor when the number of the second colonies is high.
In a possible implementation manner, after the operation of the sterilization liquid removing device is controlled to stop, that is, after S303 is executed, a reminding message is sent to remind the user to add the sterilization liquid, so that it is ensured that the sterilization liquid removing device has a sufficient amount of sterilization liquid therein when the sterilization liquid removing device is started next time, and the user experience is improved.
The reminder information may be sent by voice, text, alarm, or a combination of any two or three of the above manners.
Note that the warning information may be issued while the operation of the bacteria-removing liquid sterilizing apparatus is being stopped, that is, while S303 is being executed. The reminder may be issued while or after the second colony count in air is again acquired, i.e., while, before, or after S304 is performed. The skilled person in the art can flexibly select a specific time for sending the reminding information according to a specific application scene, as long as the purpose of reminding the user to add the sterilization liquid can be achieved.
After the operation of the sterilization liquid removing device is controlled to stop, the warning message may not be issued.
In one possible embodiment, after controlling the operation of the sterilization unit, the operation of the sterilization unit is controlled to the end of the operation of the air conditioner. That is to say, after the degerming unit starts to operate, as long as the air conditioner is in a working state, the degerming unit is always controlled to operate, and the air is sterilized through the degerming unit, so that better degerming and sterilizing effects can be obtained.
In another possible embodiment, after controlling the sterilizing unit to operate for a first preset time period, for example, the first preset time period is 2 hours. At this time, the sterilizing unit has been operated for a long time, and bacteria and viruses in the air of the indoor space have been substantially sterilized, and at this time, the sterilizing unit is controlled to stop operating. After controlling the degerming unit to stop operating for a second preset time period, for example, the second preset time period is 1 hour. Due to the fact that people in the indoor space flow, air in the outdoor environment enters the indoor space and the like, the number of bacteria and viruses in the air in the indoor space may increase again, at the moment, the sterilizing unit is controlled to operate again, and the air is sterilized and killed through the sterilizing unit. By adopting the control mode, the use of the sterilizing unit can be reduced and the service life of the sterilizing unit can be prolonged while the sterilizing and disinfecting effects are ensured.
It should be noted that, on the premise of not deviating from the principle of the present application, after the sterilization unit is controlled to operate, a person skilled in the art can flexibly select a specific time for controlling the sterilization unit to stop operating according to a specific application scenario, as long as a good sterilization and disinfection effect can be obtained.
It should be noted that, in the present application, specific values of the first threshold, the second threshold, the third threshold, the fourth threshold, the fifth threshold, the first preset time period, and the second preset time period are only described by way of example, and are not limited thereto, and a person skilled in the art may flexibly select specific values of the first threshold, the second threshold, the third threshold, the fourth threshold, the fifth threshold, the first preset time period, and the second preset time period according to a specific application scenario, as long as it is ensured that a good sterilization and disinfection effect is obtained.
In summary, in the preferred embodiment of the present invention, the operation of the sterilization unit is controlled based on the number of the first bacterial colonies in the air, so that bacteria and viruses in the air can be better removed, and a better sterilization and disinfection effect can be obtained. Through the size based on first bacterial colony quantity, control one or more operations among anion bacteria removing device, ultraviolet bacteria removing device, plasma bacteria removing device and the degerming liquid bacteria removing device to can reduce each bacteria removing device's use frequency when guaranteeing degerming, disinfection effect, prolong each bacteria removing device's life. After the operation of the sterilization liquid removing device is controlled, the sterilization liquid removing device is continuously controlled to operate when the residual amount of the sterilization liquid is larger than the preset amount, the sterilization liquid removing device is controlled to stop operating when the residual amount of the sterilization liquid is smaller than or equal to the preset amount, the reminding information is sent out after the sterilization liquid removing device is controlled to stop operating, the number of second bacterial colonies in the air is obtained again after the sterilization liquid removing device is controlled to stop operating, and further the negative ion removing device is controlled based on the number of the second bacterial colonies, the ultraviolet removing device and one or more of the plasma removing devices operate, so that the sterilization and disinfection effects can be ensured while the sterilization liquid removing device is stable and operates efficiently. After the operation of the sterilization unit is controlled, the sterilization unit can be controlled to operate to the end of the operation of the air conditioner, the operation can be stopped for a second preset time after the sterilization unit is controlled to operate for a first preset time, and then the sterilization unit is controlled to operate, so that better sterilization and disinfection effects can be obtained.
Although the foregoing embodiments describe the steps in the above sequential order, those skilled in the art can understand that, in order to achieve the effect of the present embodiments, the different steps need not be executed in such an order, and may be executed simultaneously (in parallel) or in an inverted order, and these simple changes are all within the scope of protection of the present application.
