Therefore, the specific first time threshold value and the preset interval can be set according to actual conditions.
Step S104, judging the first CO2Concentration, second CO2Concentration and third CO2Whether the concentrations are all greater than the preset CO2A concentration threshold;
above-mentioned first CO is obtained2Concentration, second CO2Concentration and third CO2After concentration, respectively judging: (1) first CO2Whether the concentration is greater than the preset CO2A concentration threshold; (2) second CO2Whether the concentration is greater than the preset CO2A concentration threshold; (3) third CO2Whether the concentration is greater than the preset CO2A concentration threshold; if yes, executing whether to enter the sleep mode judging process, otherwise, not needing to judge whether to enter the sleep mode, and clearing the first CO2Concentration, second CO2Concentration and third CO2Concentration, and controlThe air conditioner can operate according to the current mode, and when the operation reaches the set time such as 15min, a plurality of COs are obtained again according to the preset interval2And (4) concentration.
The above-mentioned first CO is judged by2Concentration, second CO2Concentration, third CO2Concentration and predetermined CO2The size relation of the concentration threshold value avoids the problem that CO is generated2Error in the sensor, resulting in a certain CO2The concentration exceeds the preset CO2The concentration threshold value, thereby causing the problem that whether the air conditioner enters the sleep mode or not by mistake, and further ensuring the control precision and efficiency of the sleep mode.

It should be noted that, in some scenarios, the first concentration variation and the second concentration variation may be calculated according to other manners, such as according to the first CO2Concentration and second CO2Calculating a first concentration change amount based on the second CO2Concentration and third CO2And calculating the second concentration variation amount according to the concentration, and the like, which can be specifically set according to the actual situation.
And S108, controlling the air conditioner to operate according to the sleep mode based on the first concentration variation, the second concentration variation and a preset first preset coefficient.
Specifically, it is determined whether the first concentration variation V1 is not greater than the first preset coefficient K1, and whether the second concentration variation V2 is not greater than the first preset coefficient K1A preset coefficient K1; namely, (1) judging that V1 is not less than K1, (2) judging that V2 is not less than K1; if the (1) to (2) are yes, controlling the air conditioner to operate according to the sleep mode; otherwise, the following process is repeated: removing first CO2Concentration, second CO2Concentration and third CO2Controlling the air conditioner to continuously operate according to the current mode, and reacquiring three COs according to a preset interval after the operation reaches a set time such as 15min2Concentration of and when three CO are collected2The concentrations are all greater than the preset CO2And when the concentration threshold value is reached, judging whether the air conditioner enters a sleep mode until the first concentration variation and the second concentration variation are not greater than a preset first preset coefficient, and controlling the air conditioner to operate according to the sleep mode.
According to the sleep mode control method of the air conditioner provided by the embodiment of the invention, when the first CO is used as the first CO2Concentration, second CO2Concentration and third CO2The concentrations are all greater than the preset CO2At the time of concentration threshold, according to the first CO2Concentration, second CO2Concentration and third CO2Calculating to obtain a first concentration variation and a second concentration variation; controlling the air conditioner to operate in a sleep mode based on the first concentration variation, the second concentration variation and a preset first preset coefficient, thereby setting operation without a user and according to indoor CO2The concentration can control the air conditioner to operate according to the sleep mode, the problem that the user is too cold or too hot due to forgetting to set the keys to enter the sleep mode before falling asleep is solved, and the comfort experience and the sleep quality of the user are improved.
Preferably, the method further comprises: judging whether the continuous operation time of the air conditioner according to the sleep mode reaches a second time threshold value; if yes, acquiring a fourth CO at the current moment2In accordance with the fourth CO2Concentration and CO2Calculating a third concentration variation amount by the average concentration; wherein, CO2Average concentration according to first CO2Concentration, second CO2Concentration and third CO2Calculating the concentration; and controlling the air conditioner to exit the sleep mode based on the third concentration variation and a preset second preset coefficient. Specifically, after the air conditioner operates according to the sleep mode, the air conditioner is acquired to sleepContinuously operating time T in the sleep mode, judging whether the time T is greater than or equal to a second time threshold T2, and if so, collecting CO at the current moment2In the concentration of fourth CO2Concentration C4, and calculating a third concentration change amount according to the following formula: v3 | (C4-C)Average) C4 |; wherein, CAverageIs CO2Average concentration, which may be according to CAverageCalculated as (C1+ C2+ C3)/3.

Therefore, according to the embodiment of the invention, the CO can be judged after the air conditioner runs for a period of time through the first preset coefficient K1 and the second preset coefficient K22Whether there is too much variation in concentration to decide whether to enter/exit sleep mode. For example, if there is user activity in the room, the user breathes out CO each time2Is varied, resulting in multiple CO detections2The concentration variation of the concentration is larger than K1, and the air conditioner does not enter the sleep mode; if the user goes to sleep, the breathing is more uniform, CO2The concentration variation amount of the concentration is small. The air conditioner enters a sleep mode; similarly, when the user wakes up from the sleep state, enters the active state and breathes unevenly, the indoor CO is influenced2And when the third concentration variation is larger than K2, automatically exiting the sleep mode.
And, in practical application, the size of each room is not fixed, the same person is in the closed space, and CO is generated2In different concentrations, if CO is set2Concentration threshold value according to collected CO2Concentration and CO2Concentration threshold value for judging whether air conditioner enters/exits sleep modeThen CO will be caused2The concentration threshold range is large and lacks universality, while the application passes through CO2The mode of concentration variation and preset coefficient of concentration automatically controls the air conditioner to enter/exit the sleep mode, can be suitable for room scenes of various sizes, has better universality and is convenient to popularize and implement in practical application.
In summary, the control method of the sleep mode of the air conditioner detects CO2Controlling whether the air conditioner operates according to the sleep mode according to the first concentration variation, the second concentration variation and a preset first preset coefficient; and in the sleep mode operation process, whether the air conditioner exits the sleep mode is controlled through the third concentration variable quantity and the preset second preset coefficient, so that the air conditioner automatically enters/exits the sleep mode, the problem that a user forgets to set a key to enter the sleep mode before falling asleep to cause supercooling or overheating is solved, and the comfort experience and the sleep quality of the user are improved.
