Fig. 1 is a schematic method diagram of an embodiment of a humidification control method in a sleep mode of an air conditioner according to the present invention.
As shown in fig. 1, according to an embodiment of the present invention, the humidification control method includes at least step S110 and step S120.
And step S110, when the preset sleep mode starting time is reached, starting the sleep mode of the air conditioner.
For example, sleep mode is turned on at 10:00 pm every night.
And step S120, starting a humidification mode of the air conditioner according to the current humidity and CO2 concentration of the room.
In a specific embodiment, whether the current humidity of a room is less than or equal to a preset humidity is judged; two different processing modes are correspondingly provided for the two situations that the current humidity is less than or equal to the preset humidity and greater than the preset humidity:
the preset parameters required by the two different treatment modes comprise preset humidity, preset concentration and/or preset concentration increasing rate. Wherein the preset humidity is a preset optimal sleep humidity. The different types of users correspond to different optimal sleep humidities (preset humidities), for example, the optimal sleep humidities corresponding to the users of different ages are different, wherein the optimal sleep humidities corresponding to the different types of users can be obtained through experiments, or the sleep humidity data of the different types of users can be obtained through big data, so as to obtain the optimal sleep humidities corresponding to the different types of users. The preset concentration can be specifically the pre-acquired carbon dioxide concentration of the environment where the user is in when the sleep of the user tends to be stable, and the condition that the user is in the stable sleep refers to the condition that the user breathes more uniformly, and the CO2 discharged at the time tends to be stable basically; specifically, the sleep stability of the user can be determined by detecting the increase rate of CO2, and when the increase rate of CO2 is smaller than a preset value, for example, an average value of the carbon dioxide concentration in a period of time when the increase rate of CO2 is smaller than the preset value (i.e., when the sleep stability of the user) is obtained as the preset concentration; different types of users can acquire different carbon dioxide concentrations of environments where the sleep tends to be stable, namely, the different types of users correspond to different preset concentrations. For example, users of different ages or different sexes correspond to different preset concentrations. The concentration of carbon dioxide in the environment where the sleep of different types of users tends to be stable can be obtained through experiments or can be obtained through big data. The preset concentration increase rate may specifically be an average value of the carbon dioxide concentration increase rates of the environments where the user is in when the sleep tends to be stable, which is acquired in advance. Different types of users (e.g., users of different ages and/or different sexes) may obtain an average of the carbon dioxide concentration increase rates of the environment in which the different users are asleep tending to stabilize (when the CO2 increase rate is less than the preset value), i.e., different types of users correspond to different preset concentration increase rates.
The preset concentration and/or preset concentration increase rate may also be obtained for the current user. For example, when the air conditioner starts a sleep mode and a humidification mode, the concentration of CO2 in a room is detected, a change curve is fitted for the change of the concentration of CO2 in the room through data processing, the concentration Wd of CO2 in the room when the sleep of a human body tends to be stable (when the slope is smaller than a preset slope value) is obtained according to the fitted change curve, and meanwhile, the average value Vp of the concentration increase rate of CO2 in the sleep period of the human body is fitted through data analysis processing. Different human physiological conditions are different, and the concentration Wd of CO2 and the average value Vp of the sleep concentration increase rate are also different when sleep tends to be stable.
(1) And if the current humidity is judged to be less than or equal to the preset humidity, starting a first humidification gear or a second humidification gear of the humidification mode according to the current CO2 concentration increase rate.
Specifically, whether the current CO2 concentration increase rate of the room is less than or equal to a preset concentration increase rate is judged; if the current CO2 concentration increase rate is judged to be less than or equal to the preset concentration increase rate, starting a second humidification gear of the humidification mode; and if the current CO2 concentration increase rate is judged to be greater than the preset concentration increase rate, starting a first humidification gear of the humidification mode. Wherein the humidification intensity of the first humidification gear is less than the humidification intensity of the second humidification gear.
For example, detecting the current humidity of a room to be in Ta, if Ta is judged to be less than or equal to Tc, further judging the concentration increase rate Ve of CO2 and the preset concentration increase rate Vp at the moment, and if Ve is less than or equal to Vp, starting a second humidification gear of a humidification mode, wherein the humidity requirement of the human body at the moment is higher; if Ve is larger than or equal to Vp, a first humidification gear of the humidification mode is started, and the requirement of the human body on humidity at the moment is high.
(2) And if the current humidity is judged to be greater than the preset humidity, determining to start the humidification mode or not according to the current CO2 concentration.
Specifically, whether the current CO2 concentration in the room is less than or equal to a preset concentration is judged; if the current CO2 concentration is judged to be less than or equal to the preset concentration, starting a first humidification gear or a second humidification gear of a humidification mode according to the current CO2 concentration increase rate; and if the current CO2 concentration is judged to be greater than the preset concentration, the humidification mode is not started. The first humidification gear or the second humidification gear of the humidification mode is started according to the current CO2 concentration increase rate, wherein the first humidification gear or the second humidification gear of the humidification mode is similar to the condition that the humidity is less than or equal to the preset humidity, namely, whether the current CO2 concentration increase rate of the room is less than or equal to the preset concentration increase rate is judged, and if the current CO2 concentration increase rate is less than or equal to the preset concentration increase rate, the second humidification gear of the humidification mode is started; and if the current CO2 concentration increase rate is judged to be greater than the preset concentration increase rate, starting a first humidification gear of the humidification mode. Wherein the humidification intensity of the first humidification gear is less than the humidification intensity of the second humidification gear.
For example, the current humidity of a room is detected to be Ta, if Ta is judged to be more than Tc, whether the current CO2 concentration Wb of the room meets Wb and Wd, and Wd is a preset concentration is further judged, and if not, namely Wb and Wd are not met, the humidification mode is not started; if Wb is less than or equal to Wd, the concentration increase rate Ve of the CO2 at the moment and the preset concentration increase rate Vp are further judged, if Ve is less than or equal to Vp, a second humidification gear of the humidification mode is started, and the humidity requirement of the human body at the moment is higher; if Ve is larger than or equal to Vp, a first humidification gear of the humidification mode is started, and the requirement of the human body on humidity at the moment is high.
Fig. 2 is a schematic method diagram of another embodiment of a humidification control method in a sleep mode of an air conditioner according to the present invention.
As shown in fig. 2, according to an embodiment of the present invention, the humidification control method further includes a step S130.
And step S130, after the humidification mode is started, determining whether to shut down the humidification mode according to the current humidity and CO2 concentration of the room in which the humidification mode is positioned.
Based on the fact that two different processing modes are corresponding to the two situations that the current humidity is smaller than or equal to the preset humidity and is larger than the preset humidity in the previous steps, whether the current humidity is smaller than or equal to the preset humidity or the current humidity is larger than the preset humidity is determined, and after the humidification mode is started, whether the humidification mode is closed or not is determined according to the current humidity and the CO2 concentration of the room where the humidification mode is started.
Specifically, whether the current humidity of the room is larger than a preset humidity and the current concentration of CO2 is larger than a preset concentration is judged; and if the current humidity is judged to be greater than the preset humidity and the current CO2 concentration is greater than the preset concentration, closing the humidification mode. And if the current humidity is not larger than the preset humidity or the current concentration of CO2 is not larger than the preset concentration, keeping the humidification mode.
For example, after the humidification mode is determined and humidification is started (the first humidification gear or the second humidification gear is turned on), whether the current humidity Ta and the current CO2 concentration Wb increase rate satisfy Ta > Tc and Wb > Wd is judged, if yes, the humidification mode is turned off, and if not, humidification is kept.
For clearly explaining the technical solution of the present invention, the following describes an execution flow of the humidification control method in the sleep mode of the air conditioner according to an embodiment of the present invention.
Fig. 3 is a schematic method diagram of a humidification control method in a sleep mode of an air conditioner according to an embodiment of the present invention. As shown in fig. 3, first, a sleep mode and a humidification mode are started every day for a preset sleep period, for example, 6:00 pm to 8:00 am (for example, the sleep mode humidification mode is started by an air conditioner control center), then a change curve is fitted to the change of the concentration of CO2 in the room through data processing, so as to obtain the concentration Wd of CO2 in the room when the human sleep is stable, and simultaneously, an average value Vp of the concentration increase rate of CO2 during the human sleep is fitted through data analysis processing. Different human physiological conditions are different, and the concentration Wd of CO2 and the average value Vp of the sleep concentration increase rate are also different when sleep tends to be stable.
The air conditioning control center obtains the concentration Wd of CO2 and the average value Vp of the concentration increase rate during sleeping through intelligent sensing and data processing, detects the current humidity of a room where the room is located to be Ta, if the Ta is judged to be less than or equal to Tc, the next step is carried out, the current values of the concentration increase rate Ve of CO2 and the preset concentration increase rate Vp are judged, if Ve is less than or equal to Vp, a second humidification gear (second gear for short) of a humidification mode is started, the humidity requirement of a human body in the current period is higher, if Ve is greater than or equal to Vp, a first humidification gear (first gear for short) of the humidification mode is started, and the humidity requirement of the human body. After the humidification mode is determined and humidification is started, whether the current humidity and the CO2 concentration increase rate meet Ta & gt Tc and Wb & gt Wd or not is judged, if yes, the humidification mode is closed, if not, humidification is kept, and then the change of Ta, Ve and Wb at every moment is fed back to complete circulation.
If the Ta is judged to be more than or equal to Tc, the next step is carried out, whether the concentration Wb of the CO2 meets the condition that Wb is less than or equal to Wd (the concentration of CO2 in the room when the sleep tends to be stable) is judged, and if not, namely Wb is more than Wd, the humidification is not started. If Wb is smaller than or equal to Wd, the next step is carried out, the sizes of the concentration increasing rate Ve of the CO2 and the preset concentration increasing rate Vp at the moment are judged, if Ve is smaller than or equal to Vp, the second humidification gear of the humidification mode is started, the requirement of the human body on the humidity at the moment is high, if Ve is larger than Vp, the first humidification gear of the humidification mode is started, and the requirement of the human body on the humidity at the moment is high. After the humidification mode is determined and humidification is started, whether the current humidity and the CO2 concentration increase rate meet Ta & gt Tc and Wb & gt Wd or not is judged, if yes, the humidification mode is closed, if not, humidification is kept, and then the change of Ta, Ve and Wb at every moment is fed back to complete circulation.
Fig. 4 is a block diagram of an embodiment of a humidification control device in a sleep mode of an air conditioner according to the present invention. As shown in fig. 4, the humidification control device 100 includes a sleep mode control unit 110 and a humidification mode control unit 120.
The sleep mode control unit 110 is configured to start a sleep mode of the air conditioner when a preset sleep mode start time is reached.
For example, sleep mode is turned on at 10:00 pm every night.
The humidification mode control unit 120 is used for turning on the humidification mode of the air conditioner according to the current humidity and the concentration of CO2 in the room.
In one embodiment, the humidification mode control unit 120 determines whether the current humidity of the room is less than or equal to a preset humidity; the humidification mode control unit 120 corresponds to two different processing modes for two cases where the current humidity is less than or equal to the preset humidity and greater than the preset humidity:
the preset parameters required by the two different treatment modes comprise preset humidity, preset concentration and/or preset concentration increasing rate. Wherein the preset humidity is a preset optimal sleep humidity. The different types of users correspond to different optimal sleep humidities (preset humidities), for example, the optimal sleep humidities corresponding to the users of different ages are different, wherein the optimal sleep humidities corresponding to the different types of users can be obtained through experiments, or the sleep humidity data of the different types of users can be obtained through big data, so as to obtain the optimal sleep humidities corresponding to the different types of users. The preset concentration can be specifically the pre-acquired carbon dioxide concentration of the environment where the user is in when the sleep of the user tends to be stable, and the condition that the user is in the stable sleep refers to the condition that the user breathes more uniformly, and the CO2 discharged at the time tends to be stable basically; specifically, the sleep stability of the user can be determined by detecting the increase rate of CO2, and when the increase rate of CO2 is smaller than a preset value, for example, an average value of the carbon dioxide concentration in a period of time when the increase rate of CO2 is smaller than the preset value (i.e., when the sleep stability of the user) is obtained as the preset concentration; different types of users can acquire different carbon dioxide concentrations of environments where the sleep tends to be stable, namely, the different types of users correspond to different preset concentrations. For example, users of different ages or different sexes correspond to different preset concentrations. The concentration of carbon dioxide in the environment where the sleep of different types of users tends to be stable can be obtained through experiments or can be obtained through big data. The preset concentration increase rate may specifically be an average value of the carbon dioxide concentration increase rates of the environments where the user is in when the sleep tends to be stable, which is acquired in advance. Different types of users (e.g., users of different ages and/or different sexes) may obtain an average of the carbon dioxide concentration increase rates of the environment in which the different users are asleep tending to stabilize (when the CO2 increase rate is less than the preset value), i.e., different types of users correspond to different preset concentration increase rates.
The preset concentration and/or preset concentration increase rate may also be obtained for the current user. For example, when the air conditioner starts a sleep mode and a humidification mode, the concentration of CO2 in a room is detected, a change curve is fitted for the change of the concentration of CO2 in the room through data processing, the concentration Wd of CO2 in the room when the sleep of a human body tends to be stable (when the slope is smaller than a preset slope value) is obtained according to the fitted change curve, and meanwhile, the average value Vp of the concentration increase rate of CO2 in the sleep period of the human body is fitted through data analysis processing. Different human physiological conditions are different, and the concentration Wd of CO2 and the average value Vp of the sleep concentration increase rate are also different when sleep tends to be stable.
(1) And if the current humidity is judged to be less than or equal to the preset humidity, starting a first humidification gear or a second humidification gear of the humidification mode according to the current CO2 concentration increase rate.
Specifically, the humidification mode control unit 120 determines whether the current CO2 concentration increase rate in the room is less than or equal to a preset concentration increase rate; if the current CO2 concentration increase rate is judged to be less than or equal to the preset concentration increase rate, starting a second humidification gear of the humidification mode; and if the current CO2 concentration increase rate is judged to be greater than the preset concentration increase rate, starting a first humidification gear of the humidification mode. Wherein the humidification intensity of the first humidification gear is less than the humidification intensity of the second humidification gear.
For example, detecting the current humidity of a room to be in Ta, if Ta is judged to be less than or equal to Tc, further judging the concentration increase rate Ve of CO2 and the preset concentration increase rate Vp at the moment, and if Ve is less than or equal to Vp, starting a second humidification gear of a humidification mode, wherein the humidity requirement of the human body at the moment is higher; if Ve is larger than or equal to Vp, a first humidification gear of the humidification mode is started, and the requirement of the human body on humidity at the moment is high.
(2) And if the current humidity is judged to be greater than the preset humidity, determining to start the humidification mode or not according to the current CO2 concentration.
