[0067] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0068] like Figure 1 As shown, the present invention provides a sterilization control method, comprising the following steps:

[0069] Step S1, start the sterilization mode, preset the threshold group; wherein the threshold group includes a first preset value Q1, a second preset value Q2, and a third preset value Q3; wherein Q1<Q2<Q3; of course, the threshold group may also include more thresholds, not limited to the three in this embodiment, so as to divide the quality interval into more intervals to achieve more refined sterilization processing;

[0070] Step S2, obtaining bacterial parameters in the room; wherein the bacterial parameters include the number of bacteria and the concentration of bacteria;

[0071] Step S3, comparing the acquired bacterial parameters with a preset threshold group to determine the quality interval of the room;

[0072] Step S4: Execute different sterilization mode operation levels based on the quality range of the room.

[0073] It should be noted that if Figure 2 As shown, after the sterilization mode is turned on and before obtaining the bacteria parameters in the room, it also includes:

[0074] Step A1, obtaining the sterilizing liquid capacity L; that is, obtaining the amount of sterilizing liquid remaining in the sterilizing device 9;

[0075] Step A2, comparing the obtained sterilizing liquid capacity L with the preset minimum capacity L1;

[0076] Step A3: when the sterilizing liquid capacity L is less than the preset minimum capacity L1, a reminder is given to replenish the sterilizing liquid;

[0077] Step A4: When the sterilization liquid capacity L≥ the preset minimum capacity L1, the sterilization mode is executed.

[0078] In order to prevent false alarms or missed alarms when a single sensor acquires parameters, in this embodiment, acquiring bacterial parameters in the room includes:

[0079] The first sensor obtains bacterial parameter A in the room;

[0080] The second sensor acquires bacterial parameter B in the room; wherein the first sensor and the second sensor are installed at different locations.

[0081] Compared with the detection of a single sensor, dual sensors can provide users with more reliable and accurate gas concentration and type data, reduce the possibility of false alarms and missed alarms, and ensure the safety of family members. In addition, when one sensor fails, the other sensor can continue to work, providing redundancy protection.

[0082] The number and concentration of bacteria detected by the sensor are A and B, and then the maximum value MAX(A, B) between the two is taken and sent to the air conditioner main control module 10 and compared with the three preset thresholds. According to the comparison results, the sterilization mode operation level is determined. Since three thresholds are preset in this embodiment, namely Q1, Q2, and Q3, four intervals are defined according to the comparison between the three preset thresholds and the maximum value of the bacterial parameter.

[0083] Specifically, the acquired bacterial parameters are compared with the preset threshold group to determine the quality range of the room, including:

[0084] When MAX(A, B) < the first preset value Q1, it is determined that the quality interval of the space is the first interval. When it is in this interval, it indicates that the number and concentration of indoor bacteria are low, and there is no need to perform the sterilization mode;

[0085] When the first preset value Q1≤MAX(A, B)<the second preset value Q2, the quality interval of the space is determined to be the second interval. When in this interval, the number and concentration of indoor bacteria are defined as a mild level, and sterilization can be turned on or off;

[0086] When the first preset value Q2≤MAX(A, B)<the third preset value Q3, it is determined that the quality interval of the space is the third interval. When in this interval, the number and concentration of indoor bacteria are defined as a moderate level, indicating that it is necessary for the user to sterilize the room, otherwise it will have an impact on the human body for a long time;

[0087] When MAX(A, B)≥the third preset value Q3, the quality interval of the space is judged to be the fourth interval. When in this interval, the number and concentration of indoor bacteria are defined as a high level, indicating that the indoor air environment is very poor and there are many bacteria, which has already affected human health. It is very necessary for users to perform sterilization.

[0088] Taking into account the different health levels of indoor users, the specific values ​​and numbers of preset thresholds can be set according to needs.

[0089] As a further improvement of the present invention, different sterilization mode operation levels are executed based on the quality range of the room, including:

[0090] When the quality interval of the judgment space is the first interval, that is, MAX(A, B)<Q1, the sterilization mode is not executed;

[0091] When the quality interval of the judgment space is the second interval, that is, Q1≤MAX(A, B)<Q2, the sterilization mode operation level S1 is executed, including:

[0092] After the sterilization device 9 is turned on and operated for a period of T in the heating current I1 and fan blade speed V1 mode, the first sensor continues to detect the bacterial parameter A, and the second sensor continues to detect the bacterial parameter B;

[0093] When MAX(A, B) < the first preset value Q1, the sterilization mode stops;

[0094] When MAX(A, B)≥first preset value Q1, the sterilization mode operation level S1 is continued to be executed.

[0095] When the quality interval of the judgment space is the third interval, that is, Q2≤MAX(A, B)<Q3, the sterilization mode operation level S2 is executed, including:

[0096] After the sterilization device 9 is turned on and operated for a period of time T in the mode of heating current I2 and fan blade speed V3, the first sensor continues to detect bacterial parameter A, and the second sensor continues to detect bacterial parameter B;

[0097] When MAX(A, B)<the second preset value Q2, the sterilization mode operation level S1 is executed;

[0098] When MAX(A, B)≥the second preset value Q2, the sterilization mode operation level S2 is continued to be executed.

[0099] When the quality interval of the space is determined to be the fourth interval, that is, MAX(A, B)≥Q3, the sterilization mode operation level S3 is executed, including:

[0100] After the sterilization device 9 is turned on and operated for a period of time T in the heating current I3 and fan blade speed V3 mode, the first sensor continues to detect the bacteria parameter A, and the second sensor continues to detect the bacteria parameter B;

[0101] When MAX(A, B)<the third preset value Q3, the sterilization mode operation level S2 is executed;

[0102] When MAX(A, B) ≥ the third preset value Q3, the sterilization mode operation level S3 is continued for time T1, and information is sent for manual sterilization;

[0103] Among them, the heating current I1<I2<I3, and the fan blade speed V1<V2<V3.

[0104] Embodiment 1:

[0105] like Figure 2 As shown, a sterilization control method of a sterilization device 9 of the present invention includes: when the user turns on the sterilization mode, first obtain the remaining capacity L of the sterilization liquid in the storage device 1. When the remaining capacity L is less than L1, it indicates that the capacity of the sterilization liquid is insufficient. The air conditioner sends information to the user's mobile terminal to remind the user to replenish the sterilization liquid, which can avoid the electric heating rod 6 from being heated in vain and causing damage; when the remaining capacity L≥L1, the air conditioner starts to execute the sterilization mode.

[0106] like Figure 3 As shown, when the air conditioner starts to execute the sterilization mode, the air conditioner first obtains the number and concentration of bacteria in the room through the first sensor and the second sensor. The present invention uses the information of the dual sensors to perform detection, which can improve the accuracy of detection. Compared with the detection of a single sensor, the dual sensor can provide users with more reliable and accurate gas concentration and type data, reduce the possibility of false alarms and missed alarms, and ensure the safety of family members. In addition, when one sensor fails, the other sensor can continue to work to provide redundant protection. The number and concentration of bacteria detected by the sensor are A and B, and then the maximum value MAX(A, B) between the two is taken and sent to the air conditioner main control module 10 and compared with the three preset thresholds. According to the comparison result, the sterilization mode operation level is determined.

[0107] In the first interval, MAX(A,B)<Q1, which indicates that the number and concentration of indoor bacteria are low and there is no need to perform sterilization mode;

[0108] In the second interval, Q1≤MAX(A,B)<Q2, the number and concentration of indoor bacteria are defined as mild level, and sterilization can be turned on or off;

[0109] In the third interval, Q2≤MAX(A,B)<Q3, the number and concentration of indoor bacteria are defined as moderate levels, indicating that it is necessary for users to sterilize the room, otherwise it will have an impact on the human body for a long time.

[0110] In the fourth interval, MAX(A,B)≥Q3, the number and concentration of indoor bacteria are defined as a high level, indicating that the indoor air environment is very poor and there are many bacteria, which has already affected human health. It is very necessary for users to perform sterilization.

[0111] Taking into account the different health levels of indoor users, the specific values ​​and numbers of preset thresholds can be set according to needs.

[0112] When MAX(A,B)<Q1, the sterilization mode is not executed;

[0113] When Q1≤MAX(A,B)<Q2, the sterilization mode operation level S1 is executed. After the T time period, the sensor re-acquires the number and concentrations of indoor bacteria A and B. If MAX(A,B)<Q1, it indicates that the sterilization is completed and the sterilization mode is turned off; if Q1≤MAX(A,B)<Q2, the current sterilization mode operation level is maintained.

[0114] When Q2≤MAX(A,B)<Q3, the sterilization mode operation level S2 is executed. After the T time period, the sensor re-acquires the number of indoor bacteria and concentrations A and B. If MAX(A,B)<Q2, it indicates that the sterilization is effective, and the sterilization mode operation level S1 continues to be executed until the sterilization is completed; if Q2≤MAX(A,B)<Q3, the current sterilization mode operation level is maintained.

[0115] When MAX(A,B)≥Q3, the sterilization mode operation level S3 is executed. After the T time period, the sensor re-acquires the number of indoor bacteria and the concentrations A and B. If MAX(A,B)<Q3, it indicates that the sterilization is effective, and the sterilization mode operation level S2 is continued to be executed. After the execution is completed, the sterilization mode operation level S1 is continued to be executed until the sterilization is completed; if MAX(A,B)≥Q3, the current sterilization mode operation level is maintained, and a message is sent to the user terminal to remind the user to perform manual sterilization.

[0116] When the air conditioner executes the sterilization mode, according to the sterilization level signal sent by the main control module 10, the electric heating rod 6 starts to heat the sterilization liquid in the storage device 1 to atomize and volatilize, and then blows it into the room through the fan blades and fully merges with the air, thereby sterilizing and disinfecting the surrounding environment.

[0117] The three different sterilization mode operation levels correspond to three operation parameters. The heating current of the electric heating rod 6 is set to I1, I2, and I3 from low to high, and the fan speed is set to V1, V2, and V3 from low to high. The specific correspondence is as follows:

[0118]
