Detailed Description
The application discloses a control method and a control device of an air conditioner and the air conditioner, so that after the air conditioner enters a night sleep mode, the energy consumption of the air conditioner is reduced on the premise of ensuring the sleep comfort of a user. It should be noted that the technical solution disclosed in the present application is suitable for a scene that needs cooling to reduce the indoor temperature.
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Referring to fig. 1, fig. 1 is a flowchart illustrating a control method of an air conditioner according to the present disclosure. The control method comprises the following steps:
s101: when a first preset condition is met, the air conditioner is switched to a sleep guiding mode, and the set temperature of the air conditioner is gradually reduced to a first temperature value in the sleep guiding mode.
It should be noted that the control method disclosed in the present application is applicable to a scenario where the air conditioner needs to cool to reduce the indoor temperature. That is, when the first preset condition is satisfied while the air conditioner is in the cooling state, the air conditioner is switched to the sleep-inducing mode.
In one possible implementation, the first preset condition is configured to: and reaching the preset night sleep mode starting time. For example, the night sleep mode start timing is previously set to 22 points, and when 22 points are reached, it is determined that the first preset condition is satisfied, and the air conditioner is switched to the guided sleep mode.
In another possible implementation manner, the first preset condition is configured to: an instruction to initiate a night sleep mode is received. For example, when a user inputs an instruction to start the night sleep mode through a remote controller or a control panel of the air conditioner, it is determined that a first preset condition is satisfied, and the air conditioner is switched to a sleep-inducing mode.
In another possible implementation, the air conditioner is wirelessly connected with the image acquisition device. After entering a night time period (such as 21 points), the air conditioner acquires an image acquired by the image acquisition device, analyzes the acquired image, determines that a first preset condition is met if the brightness of the current room is lower than a preset brightness threshold value and the user is in a lying state, and switches the air conditioner to a sleep guiding mode.
The air conditioner sets the temperature to gradually drop to a first temperature value in a sleep guiding mode. That is, in the sleep-inducing mode, the air conditioner gradually decreases the indoor temperature to induce the user to enter the sleep state from the awake state.
In the implementation, the set temperature of the air conditioner is gradually decreased to the first temperature value, and the following scheme can be adopted: the air conditioner reduces the set temperature to a first temperature value according to a preset change rate. Of course, the set temperature of the air conditioner is gradually decreased to the first temperature value, and other schemes may be adopted as long as the set temperature is decreased to the first temperature value by performing the operation of decreasing the set temperature for a plurality of times within the duration of the sleep mode.
S102: and when a second preset condition is met, switching the air conditioner from the sleep guiding mode to a shallow sleep mode, wherein the set temperature of the air conditioner is maintained at the first temperature value in the shallow sleep mode.
In a possible implementation manner, the second preset condition is configured to: the running time of the air conditioner in the sleep guiding mode reaches the preset time. The preset time period is an empirical value. For example, the preset time period is 1 and a half hours, and if the air conditioner is switched to the guided sleep mode at point 22, the air conditioner is switched from the guided sleep mode to the shallow sleep mode when 30 minutes at point 23 is reached.
In another possible implementation manner, the second preset condition is configured to: it is determined that the user entered a sleep state from an awake state. That is, when it is determined that the user enters the sleep state from the awake state, the air conditioner switches from the guided sleep-in mode to the shallow sleep mode.
In practice, the status of the user may be determined by a variety of schemes. For example, the air conditioner is wirelessly connected with a smart wearable device of a user, the smart wearable device is used for collecting physiological state information of the user, the physiological state information includes but is not limited to a heart rate, and whether the user is in a waking state or a sleeping state is determined based on the physiological state information of the user.
The air conditioner keeps the set temperature at the first temperature value under the sleep guiding mode until the deep sleep mode is switched.
S103: the outdoor temperature in a first time period is acquired, wherein the first time period is a time period when a preset air conditioner operates in a shallow sleep mode.
S104: and determining the outdoor temperature difference in the first time period according to the outdoor temperature in the first time period, and determining the second time period if the outdoor temperature difference in the first time period is greater than or equal to a preset temperature difference threshold, wherein the duration of the second time period is less than that of the first time period.
After the air conditioner is switched from the guided sleep-in mode to the shallow sleep mode, the outdoor temperature in a first time period is acquired, and the first time period is a preset time period in which the air conditioner operates in the shallow sleep mode. And then, determining the outdoor temperature difference in the first period according to the outdoor temperature in the first period. And comparing the outdoor temperature difference in the first time period with a preset temperature difference threshold, and if the outdoor temperature difference in the first time period is greater than or equal to the preset temperature difference threshold, determining a second time period, wherein the duration of the second time period is less than that of the first time period.
That is, after the air conditioner is switched from the guided sleep-in mode to the shallow sleep mode, if a large drop occurs in the outdoor temperature during a predetermined period of time during which the air conditioner is operating in the shallow sleep mode, the period of time during which the air conditioner is operating in the shallow sleep mode is shortened. For example, the air conditioner is switched from the guided sleep mode to the shallow sleep mode at 23 o ' clock 30 min, the first period of time for which the predetermined air conditioner is operated in the shallow sleep mode is 23 o ' clock 30 min to 3 o ' clock 30 min of the next day, the outdoor temperature in the first period of time is acquired, the outdoor temperature difference in the first period of time is calculated therefrom, and if the outdoor temperature difference is greater than or equal to the first temperature difference threshold (e.g., 2 ℃), the time period for which the air conditioner is operated in the shallow sleep mode is shortened, e.g., 3 o ' clock 23 o ' clock 30 min of the next day is determined as the second period of time.
It is understood that when the outdoor temperature decreases, the indoor temperature also decreases. After the air conditioner is switched to the light sleep mode, if the outdoor temperature is greatly reduced in a preset time period when the air conditioner operates in the light sleep mode, the air conditioner is switched to the deep sleep mode in advance compared with the preset time period, the set temperature of the air conditioner in the deep sleep mode is higher than a first temperature value, correspondingly, the energy consumption of the air conditioner in the deep sleep mode is lower than that in the light sleep mode, and the energy consumption of the air conditioner can be reduced by shortening the time period when the air conditioner operates in the light sleep mode. And when the outdoor temperature is greatly reduced, the indoor temperature is also reduced, and the sleeping comfort of the user can still be ensured.
S105: and when the second period of time is over, switching the air conditioner from the light sleep mode to the deep sleep mode, wherein the set temperature of the air conditioner is gradually increased to a second temperature value in the deep sleep mode.
It should be noted that if the outdoor temperature difference in the first time interval is smaller than the preset temperature difference threshold, the operation of determining the second time interval is not executed, but the following steps are executed: when the first period of time is over, the air conditioner is switched from the light sleep mode to the deep sleep mode.
In the implementation, the set temperature of the air conditioner is gradually increased to the second temperature value, and the following scheme can be adopted: the air conditioner raises the set temperature to a second temperature value according to a preset change rate. Of course, the set temperature of the air conditioner gradually rises to the second temperature value, and other schemes may be adopted as long as the set temperature is raised to the second temperature value by performing the operation of raising the set temperature for a plurality of times within the duration time of the deep sleep mode.
S106: and when a third preset condition is met, switching the air conditioner from the deep sleep mode to a mode to be started, and keeping the set temperature of the air conditioner at a second temperature value in the mode to be started.
In a possible implementation manner, the third preset condition is configured to: the preset moment is reached. For example, the preset time is 5: 30 minutes, and when the 5: 30 minutes is reached, it is determined that the third preset condition is satisfied, and the air conditioner is switched from the deep sleep mode to the standby mode.
In another possible implementation manner, the third preset condition is configured to: it is determined that the user entered an awake state from a sleep state. That is, when it is determined that the user enters the awake state from the sleep state, the air conditioner is switched from the deep sleep mode to the standby mode.
The application discloses a control method of an air conditioner, under the condition that the air conditioner is in a cooling mode, when a first preset condition is met, the air conditioner is switched to a sleep guiding mode, under the sleep guiding mode, the set temperature of the air conditioner is gradually reduced to a first temperature value, then, when a second preset condition is met, the air conditioner is switched from the sleep guiding mode to a light sleep mode, under the light sleep mode, the set temperature of the air conditioner is maintained at the first temperature value, the outdoor temperature difference in a first time period (the preset time period when the air conditioner operates in the light sleep mode) is obtained, if the outdoor temperature difference in the first time period is larger than or equal to a first temperature difference threshold value, a second time period is determined, the duration of the second time period is smaller than the duration of the first time period, then, when the second time period is over, the air conditioner is switched from the light sleep mode to a deep sleep mode, under the deep sleep mode, the set temperature of the air conditioner is gradually increased to the second temperature value, and then when a third preset condition is met, switching the air conditioner from the deep sleep mode to a mode to be started, and maintaining the set temperature of the air conditioner at a second temperature value in the mode to be started.
It can be seen that, in the control method of the air conditioner disclosed in the present application, after the air conditioner is switched to the light sleep mode, an outdoor temperature difference within a predetermined time period in which the air conditioner operates in the light sleep mode is determined, and if the outdoor temperature difference is greater than or equal to a preset temperature difference threshold, the time period in which the air conditioner operates in the light sleep mode is shortened, that is, the air conditioner is switched to the deep sleep mode in advance compared to the predetermined time period in which the air conditioner operates in the light sleep mode, wherein energy consumption of the air conditioner operating in the deep sleep mode is less than energy consumption of the air conditioner operating in the light sleep mode, and therefore, energy consumption of the air conditioner can be reduced. And when the outdoor temperature is greatly reduced, the indoor temperature is also reduced, and the sleeping comfort of the user can still be ensured.
In one embodiment, the second time period is determined using the following scheme:
1) and determining a second time length according to the outdoor temperature difference in the first time period.
The outdoor temperature difference in the first time period is in a negative correlation relation with the second time period, the second time period is shorter than the first time period, and the first time period is the time period of the first time period. That is, the greater the outdoor temperature difference in the first time period, the smaller the second time period, and correspondingly, the smaller the outdoor temperature difference in the first time period, the larger the second time period.
2) And taking the time when the air conditioner is switched from the sleep-leading mode to the shallow sleep mode as the starting time of the second time period, and adding a second time length on the basis of the starting time to obtain the ending time of the second time period.
In a possible implementation manner, the second time length is determined according to the outdoor temperature difference in the first time period, and the following scheme is adopted:
comparing the outdoor temperature difference in the first time period with the preset N temperature intervals;
and if the outdoor temperature difference in the first time interval is in the ith temperature interval of the N temperature intervals, subtracting a preset time length adjusting value xi from the first time length to obtain a second time length.
And N is an integer greater than 1, in the N temperature intervals, the lower limit value of the ith temperature interval is greater than the upper limit value of the (i-1) th temperature interval, and any one temperature value only belongs to one temperature interval.
This is exemplified here.
3 temperature intervals are preset, and the preset time length adjustment value is 0.5 hour. The 1 st temperature interval is: t is more than or equal to 2 ℃ and less than 4 ℃; the 2 nd temperature interval is: t is more than or equal to 4 ℃ and less than 6 ℃; the 3 rd temperature interval is: t is more than or equal to 6 ℃. Wherein T is the outdoor temperature difference in the first time period.
The predetermined period of time that the air conditioner is operated in the doze mode (i.e., the first period of time) is from 23 o 'clock 30 minutes to 3 o' clock 30 minutes of the next day for 4 hours. Assuming that the outdoor temperature difference in the first period is 3 ℃, the second time period is 3.5 hours, the starting time of the second period is 23 o 'clock and 30 minutes, and the ending time of the second period is 3 o' clock of the next day. Assuming that the outdoor temperature difference in the first period is 4 ℃, the second time period is 3 hours, the starting time of the second period is 23 o 'clock 30 minutes, and the ending time of the second period is 2 o' clock 30 minutes of the next day.
In one embodiment, the outdoor temperature difference in the first period is determined according to the outdoor temperature in the first period, and the following scheme is adopted:
and calculating the difference value between the outdoor temperature at the starting moment of the first time interval and the outdoor temperature at the ending moment of the first time interval, and taking the difference value as the outdoor temperature difference in the first time.
For example: the predetermined air conditioner is operated in the doze mode for a period of time (i.e., a first period of time) from 23 o 'clock 30 minutes to 3 o' clock 30 minutes on the next day, and then a difference between the outdoor temperature at the start time (i.e., 23 o 'clock 30 minutes) and the outdoor temperature at the end time (3 o' clock 30 minutes on the next day) of the first period of time is calculated as the outdoor temperature difference in the first time.
In another embodiment, the outdoor temperature difference in the first period is determined according to the outdoor temperature in the first period, and the following scheme is adopted:
and calculating the difference value between the outdoor average temperature at the starting stage of the first time interval and the outdoor average temperature at the ending stage of the first time interval, and taking the difference value as the outdoor temperature difference in the first time interval.
Wherein, the starting stage of the first time interval refers to: starting from the starting time of the first period and the period is a third period, and the ending period of the first period is as follows: and ending the ending time of the first time interval, wherein the time length is the third time length. The third time period may be configured to be 10 minutes, although the third time period may be other values.
In practice, the outdoor temperature during the first time period may be obtained from the weather forecast data. The weather forecast data includes weather information for a future period of time and also includes temperature information for a future period of time, such as a temperature profile, based on which the outdoor temperature for the first period of time can be obtained.
In an implementation, the first temperature value and the second temperature value may be preset empirical values.
Considering that the suitable temperatures required by different people in different sleep stages are different, the first temperature value and the second temperature value in the present application can be determined by other schemes.
In one embodiment, the first temperature value in the present application is determined as follows: determining the user attribute, and acquiring a temperature value corresponding to the user attribute in the sleep-inducing mode as a first temperature value.
In one embodiment, the second temperature value in the present application is determined as follows: and determining the user attribute, and acquiring a temperature value corresponding to the user attribute in the deep sleep mode as a second temperature value.
Alternatively, the user attributes may include children, young people, and old people.
Of course, the division of the user attributes may also take into account other factors, such as the gender of the user, in addition to the age of the user. For example, the user attributes may include female children, male children, female young people, male young people, female old people, and male old people.
That is, temperature values corresponding to the user attributes in the sleep guidance mode are preset, and after the user attributes of the current room are determined, the temperature values corresponding to the user attributes of the current room are acquired according to the preset temperature values corresponding to the user attributes in the sleep guidance mode, and the temperature values are used as first temperature values. Presetting temperature values corresponding to the user attributes in the deep sleep mode, after determining the user attributes of the current room, acquiring the temperature values corresponding to the user attributes of the current room according to the preset temperature values corresponding to the user attributes in the deep sleep mode, and taking the temperature values as second temperature values.
Referring to fig. 2, fig. 2 is a schematic view of a night sleep curve generated based on the control method of the air conditioner disclosed in the present application.
In fig. 2, L1 is a night sleep curve generated by the control method of the air conditioner disclosed in the present application when a large temperature drop does not occur at night, and L2 is a night sleep curve generated by the control method of the air conditioner disclosed in the present application when a large temperature drop occurs at night.
The air conditioner enters the sleep-inducing mode at point 22 and the set temperature of the air conditioner is gradually lowered to a first temperature value (25 c in fig. 2).
