Detailed Description
It should be noted that the embodiments and features of the embodiments may be combined with each other without conflict.
The present invention will be described in detail below with reference to the embodiments with reference to the attached drawings.
Example 1
As shown in fig. 1, a sterilization method of an air conditioner includes the steps of:
and S100, detecting the bacterial quantity of the air passing through the air inlet and/or the air outlet of the indoor unit 6 in real time under the working state of the air conditioner, and analyzing the bacterial quantity to obtain a bacterial quantity analysis value.
Specifically, when the air conditioner is used for cooling or heating, the fan of the indoor unit 6 is rotated and can drive indoor air to flow through an indoor air duct for heat exchange, in the process, the air flows in from the air inlet and flows out from the air outlet, the bacterial quantity of the air in the room can be reflected by detecting the bacterial quantity passing through the air inlet of the indoor unit 6, and the bacterial quantity of the air passing through the air outlet of the indoor unit 6 can be reflected by detecting the bacterial quantity passing through the air outlet of the indoor unit 6.
In summary, the detection of the number of bacteria has three modes: 1. detecting the number of bacteria at the air inlet of the indoor unit 6 independently; 2. detecting the number of bacteria at the air outlet of the indoor unit 6 independently; 3. the air inlet and the air outlet detect the number of bacteria together.
After the air conditioner is started and operated for a period of time every time, the number of the obtained bacteria can be analyzed within 5-10 minutes, and when the number of the bacteria at the air inlet or the air outlet of the indoor unit 6 is only detected, the analysis process is as follows: and averaging the bacterial numbers detected by the current time node and other time nodes, and taking the obtained average value as a bacterial number analysis value, or directly taking the bacterial number detected by the current time node as the bacterial number analysis value.
When detecting the bacterial number of the air inlet or the air outlet of the indoor unit 6 together, the analysis process is as follows: the bacterial numbers detected by the current time nodes of the indoor unit and the outdoor unit are summed, the obtained bacterial number sum is used as a bacterial number analysis value, and the formula for calculating the bacterial number sum of the air inlet and the air outlet of the air duct of the indoor unit 6 is as follows: p _3 ═ p _2+ p _1, where p _1 — the number of bacteria passing through the air inlet of the indoor unit 6; p _ 2-number of bacteria passing through air outlet of indoor unit 6; p _ 3-the total of the number of bacteria in the air inlet and outlet of the air duct of the indoor unit 6. Or the difference between the bacterial numbers detected by the two current time nodes is obtained, the difference value of the obtained bacterial numbers is used as a bacterial number analysis value, namely, the formula for calculating the difference value of the bacterial numbers of the air inlet and the air outlet of the air duct of the indoor unit 6 is as follows: p _3 ═ p _2-p _1, where p _1 — the number of bacteria passing through the air inlet of the indoor unit 6; p _ 2-number of bacteria passing through air outlet of indoor unit 6; p _ 3-difference of the number of bacteria in the air inlet and outlet of the 6 air ducts of the indoor unit.
S200: if the ratio of the bacteria number analysis value to the threshold value is smaller than the first value, the indoor unit 6 does not enter the sterilization mode.
Specifically, different detection modes have different threshold ranges, as follows:
when the number of bacteria at the air outlet or the air inlet of the indoor unit is detected, the value ranges of the thresholds of the two analysis modes are the same, and are 2200 and 2800 colony counts/m 3;
when the bacterial numbers of the air outlet and the air inlet of the indoor unit are detected simultaneously, the value range of the threshold value compared with the sum of the bacterial numbers is 4400-5600 colony number/m 3, and the value range of the threshold value compared with the difference value of the bacterial numbers is 1100-1400 colony number/m 3.
In actual operation, a reasonable mode and a threshold range are selected according to different environments.
The first value range is 0.75-0.85, after the value is reasonably taken, when the ratio of the bacteria quantity analysis value to the threshold value is smaller than the first value, the indoor unit 6 works in a normal mode, and the indoor unit 6 does not perform sterilization treatment.
S300: if the ratio of the analyzed value of the number of bacteria to the threshold value is not less than the first value, the indoor unit 6 performs sterilization treatment.
The method comprises the following steps:
s301: if the ratio of the bacteria number analysis value to the threshold value is not less than the first value and is less than the second value, the indoor unit 6 sends out a sterilization prompt.
Specifically, when the ratio of the analyzed value of the number of bacteria to the threshold value is not less than the first value and is less than the second value, the indoor unit 6 sends out a sterilization prompt. The sterilization prompting mode can be that the panel of the indoor unit 6 continuously flickers for 30 seconds every 30 minutes, wherein the light can be yellow light, and the function of early warning is achieved through vision. In another embodiment, the indoor unit 6 generates 30-second ring tone every 30 minutes, and plays a role of early warning through hearing; or the light color changes along with the increase of the ratio of the bacteria number analysis finger to the threshold value through the mode that the indicator lamp continuously emits light, for example, the color changes from yellow to red, and the mode that the panel display box displays the warning mark.
S302: if the manual switch is triggered in the process that the indoor unit 6 sends out the sterilization prompt, the indoor unit 6 enters the sterilization mode.
Specifically, in the process that the indoor unit 6 sends out the sterilization prompt, after the manual switch is triggered by the user, the inside of the indoor unit 6 is sterilized, and after the ratio of the bacteria quantity analysis value to the threshold value is smaller than the first numerical value, the indoor unit 6 exits from the sterilization mode. Therefore, the sterilization control can be artificially carried out, the sterilization operation can be carried out in advance, and the bacteria number is prevented from reaching the maximum value.
In this step, the triggering mode of the manual switch includes: the manual switch is a starting key arranged on the indoor unit of the air conditioner, and is triggered when a user touches or presses the manual switch, or the manual switch is a remote controller and is triggered when the user touches or presses the manual switch.
In this step, after the manual switch is triggered by the user, the panel of the indoor unit 6 stops sending out the sterilization prompt, thereby avoiding the loss of electric energy.
S303, if the ratio of the analyzed value of the number of bacteria to the threshold value is not less than the second value, the indoor unit 6 enters the sterilization mode.
Specifically, when the ratio of the analyzed value of the bacterial number to the threshold value is not less than the second value, the inside of the indoor unit 6 is directly sterilized, and in the process of sterilizing, if the ratio of the analyzed value of the bacterial number to the threshold value is greater than the first value and less than the second value, the indoor unit 6 does not send out a sterilization prompt and continues to perform sterilization; and when the ratio of the bacteria quantity analysis value to the threshold value is smaller than a first value, the indoor unit 6 exits the sterilization mode. Therefore, when the indoor unit 6 is used for directly sterilizing, the detected bacteria quantity can be reduced, and when the ratio of the bacteria quantity analysis value to the threshold value is not smaller than the first numerical value and smaller than the second numerical value, the sterilization prompt stage is skipped, so that the waste of electric energy is avoided.
In this embodiment, when the analyzed value of the number of bacteria is compared with the threshold value, there are three cases in the ratio, as shown in fig. 2, which may be determined step by step, so as to avoid errors; as shown in fig. 3, it is also possible to directly obtain the determination result and select one of the three cases, thereby achieving a high reaction speed.
The following description is given by way of example only, in which the number of bacteria at the air outlet of the indoor unit 6 is detected separately, and the number of bacteria detected at the latest time point is taken, and the ratio is determined step by step: wherein the threshold value is the number of bacteria in the air flow under the ventilation state of the indoor unit 6, and 2500 colony counts/cubic meter is taken; the first numerical value is the minimum value of the ratio of the analyzed value of the number of bacteria to the threshold value, and the first numerical value is 0.8; the second value is the maximum value of the ratio of the analyzed value of the number of bacteria to the threshold value, and the value is 1.
After the air conditioner works, when the number of bacteria at the nearest time point of the air outlet is 1750 colony number/cubic meter, the ratio of the bacteria number to the threshold value is 0.7 and is less than 0.8, the indoor unit 6 works in a normal mode, and the indoor unit 6 does not carry out sterilization treatment; after the lapse of time, when the number of bacteria at the nearest time point of the air outlet is 2250 colony count/cubic meter, the ratio of the detected number to the threshold value is 0.9, which is not less than 0.8 and less than 1, the panel of the indoor unit 6 continuously flickers for 30 seconds at intervals of 30 minutes, at this time, there are two cases,
in the first case: the manual switch is triggered, the indoor unit 6 is sterilized, the panel of the indoor unit 6 stops emitting light, and the indoor unit 6 exits from the sterilization mode after the ratio of the bacteria number analysis value to the threshold value is less than 0.8;
in the second case: the manual switch is not triggered, after the lapse of time, after detecting that the number of bacteria at the nearest time point of the air outlet is 2500 colony numbers/cubic meter, the ratio of the number of bacteria to the threshold value is 1, the number of bacteria is not less than 1, the indoor unit 6 directly performs sterilization treatment, and stops sending out sterilization prompts (the panel of the indoor unit 6 stops sending out light), and after the ratio of the analysis value of the number of bacteria to the threshold value is less than 0.8, the indoor unit 6 exits from the sterilization mode.
