Specifically, the air conditioner is provided with an upper air outlet and a lower air outlet. In the upper air outlet and the lower air outlet, one air outlet can be used for air inlet, and the other air outlet can be used for air outlet.
For example: the air conditioner is provided with an upper air outlet and a lower air outlet, and can adopt an upper air outlet mode or a lower air outlet mode according to different requirements; therefore, through the up-down air supply air conditioner, corresponding parameters such as an up-down air outlet mode, air quantity, an air outlet angle and temperature are adjusted in real time, the indoor environment can be guaranteed to rapidly reach the parameters required by a user in a sleeping state, and the comfort level of the user is met.
For example: as shown in fig. 6, the upper and lower air outlets can be adjusted according to the corresponding air supply manner, when the upper portion is supplied with air, the lower air outlet is the air outlet, and when the lower portion is supplied with air, the upper air outlet is the air outlet; the air conditioner in fig. 6 is composed of an upper air outlet and a lower air outlet (as the upper air outlet 1 in fig. 6), a heat exchanger 3, a fan 5, an air supply duct and other parts; and also has a lower air inlet 4. The heat exchanger is composed of two rows or a plurality of rows of heat exchange tubes, and the whole heat exchanger is a cylindrical or square heat exchanger. The fan includes two axial fan, can realize air-out under the air-out, the heating mode in the refrigeration mode, and the user also can realize air-out under the refrigeration mode and air-out on the heating mode through setting up by oneself. The fan can realize air volume adjustment by controlling the fan rotating speed, the fan running quantity and the fan steering. The fan is installed inside the air supply duct.
Therefore, under the condition that the air conditioner enters the set sleep mode, the operation parameters of the air conditioner are controlled in stages according to the conditions of the current operation time length of the air conditioner, the current operation mode, the indoor environment temperature, the PMV value of a human body and the like, so that the comfort requirements of different users are met, and the air conditioner is good in humanization.
The operation parameters of the air conditioner may include: the air conditioner comprises a compressor operation frequency, an air outlet mode, an air outlet quantity and/or an air outlet angle.
Therefore, the accuracy and the reliability of air conditioner control are improved beneficially through the operation parameters in various forms.
Optionally, controlling the operating parameters of the air conditioner in stages may include: a first stage of controlling the operation parameters of the air conditioner in stages.
Referring to the flowchart of fig. 2, a specific process of the step S120 of the first stage of controlling the operating parameters of the air conditioner in stages is further described, where the specific process includes: step S210 to step S230.
In step S210, it is determined whether the current operation time period of the air conditioner in the set sleep mode has reached the first set time period, that is, it is determined whether the air conditioner has operated in the set sleep mode for the first set time period.
For example: after the air conditioner is started to operate, when a user sets an operation sleep mode and a refrigeration mode, an air supply mode is set to be bottom air inlet and upper air outlet, and the air conditioner operates according to a preset temperature reference value T0And setting parameters such as fan rotating speed, fan operation quantity and the like to adjust air quantity. In the refrigeration mode, when the user sets corresponding parameters but does not enter the sleep mode, the system performs the operation according to the set temperature valueAnd correspondingly setting parameters to operate.
For another example: after the air conditioner is started to operate, when a user sets an operation sleep mode and a heating mode, an air supply mode is set to be an upper air inlet mode and a lower air outlet mode, and the air conditioner operates according to a preset temperature reference value T0And setting parameters such as fan rotating speed, fan operation quantity and the like to adjust air quantity. In the heating mode, when the user sets corresponding parameters but does not enter the sleep mode, the system performs corresponding parameter setting operation according to the set temperature value.
In step S220, if the current operation time period of the air conditioner in the set sleep mode has reached the first set time period, that is, if the air conditioner has operated in the set sleep mode for the first set time period, it is determined whether a temperature difference between the indoor ambient temperature and the target temperature is greater than a set temperature threshold.
In step S230, if the temperature difference between the indoor ambient temperature and the target temperature is greater than the set temperature threshold, performing a first setting adjustment on the operation parameters of the air conditioner according to the current operation mode of the air conditioner. And if the temperature difference between the indoor environment temperature and the target temperature is smaller than the set temperature threshold, performing second setting adjustment on the operation parameters of the air conditioner according to the current operation mode of the air conditioner. Of course, if the temperature difference between the indoor ambient temperature and the target temperature is equal to the set temperature threshold, the operation parameters of the air conditioner are controlled to keep the original state operation.
Therefore, under the condition that the current operation time of the air conditioner in the set sleep mode reaches the first set time, the corresponding setting adjustment is carried out on the operation parameters of the air conditioner according to the condition that the temperature difference value between the indoor environment temperature and the target temperature is greater than or less than the set temperature threshold value, so that the operation parameters of the air conditioner are adjusted in time according to the condition of the indoor environment temperature, the comfort experience of a user is better improved, and the user can sleep in a more comfortable environment.
More optionally, the performing the first setting adjustment on the operation parameter of the air conditioner according to the current operation mode of the air conditioner in step S230 may include: if the current operation mode of the air conditioner is a refrigeration mode, changing a first set air outlet mode in the refrigeration mode by changing the direction of a fan of the air conditioner so as to change the air outlet mode of the air conditioner from that of lower air outlet air inlet and upper air outlet into that of upper air outlet air inlet and lower air outlet; and increasing the rotating speed of the first set fan in the refrigeration mode and/or increasing the running number of the first set fan in the refrigeration mode. Or if the current operation mode of the air conditioner is a heating mode, changing the first set air outlet mode in the heating mode by changing the direction of the fan of the air conditioner so as to change the air outlet mode of the air conditioner from the air inlet at the upper air outlet and the air outlet at the lower air outlet into the air inlet at the lower air outlet and the air outlet at the upper air outlet; and reducing the first set fan speed in the heating mode and/or reducing the first set fan operation number in the heating mode. The first set air outlet mode in the cooling mode may be the same as or different from the first set air outlet mode in the heating mode.
For example: in the cooling mode, when the operation time t is0Then, the infrared sensor detects the indoor average temperature T1And making corresponding temperature judgment, when the judgment condition { T } is satisfied1-T0＞△T1And adjusting the rotation direction of the fan, changing the upper air supply mode into the upper air supply mode, discharging air from the lower air supply mode, increasing the rotation speed of the fan and increasing the air quantity.
For another example: in heating mode, when the operation time t is0Then, the infrared sensor detects the human body temperature value T1And making corresponding temperature judgment, when the judgment condition { T } is satisfied1-T0＞△T1And the direction of the fan is changed into lower air inlet and upper air outlet, so that the running quantity of the fan is reduced, the rotating speed of the fan is reduced, and the air quantity is reduced.
Therefore, when the temperature difference between the indoor environment temperature and the target temperature is larger than the set temperature threshold, the air outlet mode of the air conditioner is changed in the refrigeration mode, the air outlet quantity is increased, and the indoor environment temperature can be improved more quickly; change the air-out mode of air conditioner under the heating mode to reduce the air output, can improve indoor ambient temperature sooner, thereby promote the regulation efficiency of air conditioner more high-efficiently and accurately, promote user's travelling comfort and experience.
More optionally, the second setting and adjusting of the operation parameters of the air conditioner according to the current operation mode of the air conditioner in step S230 may include: and if the current operation mode of the air conditioner is the refrigeration mode, controlling the air conditioner to still output air according to a first set air-out mode in the refrigeration mode, and reducing the rotating speed of a first set fan in the refrigeration mode and/or reducing the operation number of the first set fan in the refrigeration mode. Or if the current operation mode of the air conditioner is the heating mode, controlling the air conditioner to adjust the air volume according to the first set fan rotating speed and/or the first set fan operation number in the heating mode.
For example: in the cooling mode, when the operation time t is0Then, the infrared sensor detects the indoor average temperature T1And making corresponding temperature judgment, when the judgment condition { T } is satisfied1-T0＜△T1And keeping the rotation direction of the fan unchanged, reducing the running quantity or the rotating speed of the fan and reducing the air quantity.
For another example: in heating mode, when the operation time t is0Then, the infrared sensor detects the human body temperature value T1And making corresponding temperature judgment, when the judgment condition { T } is satisfied1-T0＜△T1Keeping the upper air inlet and the lower air outlet of the fan, and adjusting the air quantity.
Therefore, the air outlet mode of the air conditioner is kept in the refrigeration mode and the air outlet quantity is reduced by the fact that the temperature difference between the indoor environment temperature and the target temperature is smaller than the set temperature threshold; the air outlet mode of the air conditioner is kept in the heating mode, the air outlet quantity is kept, the indoor environment temperature can be improved more quickly and accurately, and the comfort feeling of a user is improved.
Further optionally, the controlling the operation parameters of the air conditioner in steps S120 may further include: and a second stage of controlling the operation parameters of the air conditioner in stages.
The following further describes a specific process of the second stage of controlling the operating parameters of the air conditioner in stages in step S120 with reference to a flowchart of an embodiment of the second stage of controlling the operating parameters of the air conditioner in stages in the method shown in fig. 3, which may include: step S310 and step S320.
Step S310, after the second set time length is adjusted according to the first setting of the operation parameter of the air conditioner according to the current operation mode of the air conditioner, or the third set time length is adjusted according to the second setting of the operation parameter of the air conditioner according to the current operation mode of the air conditioner, whether the PMV value of the human body is larger than or equal to the upper limit of the set index range or whether the PMV value of the human body is smaller than or equal to the lower limit of the set index range is determined.
And step S320, if the PMV value of the human body is greater than or equal to the upper limit of the set index range, performing third setting adjustment on the operation parameters of the air conditioner according to the current operation mode of the air conditioner. And if the PMV value of the human body is smaller than or equal to the lower limit of the set index range, performing fourth setting adjustment on the operation parameters of the air conditioner according to the current operation mode of the air conditioner. Of course, if the PMV value of the human body is greater than the lower limit of the set index range and less than the upper limit of the set index range, the original air outlet mode is maintained, and the air volume is adjusted by combining the specific PMV value of the human body. For example: the human PMV value can be detected, the air supply mode is selected according to different PMV values, the air outlet mode and the air outlet angle are adjusted, the temperature is quickly adjusted, and the comfort level is met.
For example: after the second set time length is adjusted according to the first setting of the operation parameters of the air conditioner in the current operation mode of the air conditioner, whether the PMV value of the human body is larger than or equal to the upper limit of the set index range or whether the PMV value of the human body is smaller than or equal to the lower limit of the set index range is determined. And if the PMV value of the human body is larger than or equal to the upper limit of the set index range, performing third setting adjustment on the operation parameters of the air conditioner according to the current operation mode of the air conditioner. And if the PMV value of the human body is smaller than or equal to the lower limit of the set index range, performing fourth setting adjustment on the operation parameters of the air conditioner according to the current operation mode of the air conditioner. Of course, if the PMV value of the human body is greater than the lower limit of the set index range and less than the upper limit of the set index range, the original air outlet mode is maintained, and the air volume is adjusted by combining the specific PMV value of the human body.
Or after the operation parameters of the air conditioner are subjected to second setting adjustment according to the current operation mode of the air conditioner for a third set time period, determining whether the PMV value of the human body is greater than or equal to the upper limit of the set index range or determining whether the PMV value of the human body is less than or equal to the lower limit of the set index range. And if the PMV value of the human body is larger than or equal to the upper limit of the set index range, carrying out fifth setting adjustment on the operation parameters of the air conditioner according to the current operation mode of the air conditioner. And if the PMV value of the human body is less than or equal to the lower limit of the set index range, carrying out sixth setting adjustment on the operation parameters of the air conditioner according to the current operation mode of the air conditioner. Of course, if the PMV value of the human body is greater than the lower limit of the set index range and less than the upper limit of the set index range, the original air outlet mode is maintained, and the air volume is adjusted by combining the specific PMV value of the human body. If { | PMV | < 2}, the original air supply mode is maintained, and the air volume is adjusted by combining a specific PMV value.
For example: in the cooling mode or the heating mode, when the air conditioner operates according to the upper air outlet time length t1Or lower air-out operation t2Then, the infrared sensor detects the temperature of the human body and performs PMV judgment.
Therefore, after the second set time length is adjusted according to the first set of the operation parameters of the air conditioner in the current operation mode of the air conditioner or the third set time length is adjusted according to the second set of the operation parameters of the air conditioner in the current operation mode of the air conditioner, the operation parameters of the air conditioner are controlled according to the size relation between the PMV value of the human body and the set index range, the operation parameters of the air conditioner can be adjusted in time more accurately according to the body temperature conditions of different users, and the respective comfort feeling of the different users is improved.
More optionally, the third setting and adjusting of the operation parameters of the air conditioner according to the current operation mode of the air conditioner in step S320 may include: in the refrigeration mode, the air conditioner is controlled to output air in an air output mode opposite to the first set air output mode in the refrigeration mode, namely the air conditioner is controlled to output air in an air output mode after the first set air output mode in the refrigeration mode is changed by changing the direction of a fan of the air conditioner, so that the air output mode of the air conditioner is changed from that of lower air outlet air inlet and that of upper air outlet air inlet and that of lower air outlet; and increasing the running frequency of the compressor in the refrigeration mode, increasing the rotating speed of the first set fan in the refrigeration mode, increasing the running number of the first set fan in the refrigeration mode, and/or increasing the air outlet angle in the refrigeration mode to increase the air outlet quantity. Or, in the heating mode, the air conditioner is controlled to output air according to the first set air output mode in the heating mode, and the operation frequency of the compressor in the heating mode is reduced, the rotation speed of the first set fan in the heating mode is reduced, the operation number of the first set fan in the heating mode is reduced, and/or the air output angle in the heating mode is reduced to reduce the air output.
For example: performing third setting adjustment on the operation parameters of the air conditioner according to the current operation mode of the air conditioner, or performing fifth setting adjustment on the operation parameters of the air conditioner according to the current operation mode of the air conditioner, which may include: in the refrigeration mode, the air conditioner is controlled to output air in an air output mode opposite to the first set air output mode in the refrigeration mode, namely the air conditioner is controlled to output air in an air output mode after the first set air output mode in the refrigeration mode is changed by changing the direction of a fan of the air conditioner, so that the air output mode of the air conditioner is changed from that of lower air outlet air inlet and that of upper air outlet air inlet and that of lower air outlet; and increasing the running frequency of the compressor in the refrigeration mode, increasing the rotating speed of the first set fan in the refrigeration mode, increasing the running number of the first set fan in the refrigeration mode, and/or increasing the air outlet angle in the refrigeration mode to increase the air outlet quantity. Or, in the heating mode, the air conditioner is controlled to output air according to the first set air output mode in the heating mode, and the operation frequency of the compressor in the heating mode is reduced, the rotation speed of the first set fan in the heating mode is reduced, the operation number of the first set fan in the heating mode is reduced, and/or the air output angle in the heating mode is reduced to reduce the air output.
For example: under the refrigeration mode, when { PMV is more than or equal to 2}, a human body feels warm and hot, an upper air inlet and lower air outlet mode is set, the running frequency of the compressor is properly increased, the air quantity is increased, and the air outlet angle is adjusted.
For another example: under the heating mode, when { PMV is more than or equal to 2}, a human body feels warm and hot, a lower air inlet and upper air outlet mode is set, the running frequency of the compressor is properly reduced, the air quantity is reduced, and the air outlet angle is adjusted.
Therefore, under the condition that the PMV value of the human body is larger than or equal to the upper limit of the set index range, the air conditioner is controlled to change the air outlet mode and increase the air outlet quantity and the air outlet temperature under the cooling mode, the air conditioner is controlled to keep the air outlet mode and reduce the air outlet quantity and the air outlet temperature under the heating mode, the indoor environment temperature can be improved more quickly and accurately, and the comfort feeling of the human body is improved.
More optionally, the fourth setting and adjusting of the operation parameters of the air conditioner according to the current operation mode of the air conditioner in step S320 may include: and in the refrigeration mode, controlling the air conditioner to output air according to a first set air output mode in the refrigeration mode, reducing the running frequency of a compressor in the refrigeration mode, reducing the rotating speed of a first set fan in the refrigeration mode, reducing the running number of the first set fan in the refrigeration mode, and/or reducing the air output angle in the refrigeration mode to reduce the air output. Or, in the heating mode, the air conditioner is controlled to output air in an air output mode opposite to the first set air output mode in the heating mode, namely, the air conditioner is controlled to output air in an air output mode after the first set air output mode in the heating mode is changed by changing the direction of a fan of the air conditioner, so that the air output mode of the air conditioner is changed from that of lower air outlet air inlet and that of upper air outlet to that of upper air outlet; and increasing the running frequency of the compressor in the heating mode, increasing the rotating speed of the first set fan in the heating mode, increasing the running number of the first set fan in the heating mode, and/or increasing the air outlet angle in the heating mode to increase the air outlet quantity.
For example: performing a fourth setting adjustment on the operation parameters of the air conditioner according to the current operation mode of the air conditioner, or performing a sixth setting adjustment on the operation parameters of the air conditioner according to the current operation mode of the air conditioner, which may include: and in the refrigeration mode, controlling the air conditioner to output air according to a first set air output mode in the refrigeration mode, reducing the running frequency of a compressor in the refrigeration mode, reducing the rotating speed of a first set fan in the refrigeration mode, reducing the running number of the first set fan in the refrigeration mode, and/or reducing the air output angle in the refrigeration mode to reduce the air output. Or, in the heating mode, the air conditioner is controlled to output air in an air output mode opposite to the first set air output mode in the heating mode, namely, the air conditioner is controlled to output air in an air output mode after the first set air output mode in the heating mode is changed by changing the direction of a fan of the air conditioner, so that the air output mode of the air conditioner is changed from that of lower air outlet air inlet and that of upper air outlet to that of upper air outlet; and increasing the running frequency of the compressor in the heating mode, increasing the rotating speed of the first set fan in the heating mode, increasing the running number of the first set fan in the heating mode, and/or increasing the air outlet angle in the heating mode to increase the air outlet quantity.
For example: under the refrigeration mode, when { PMV is less than or equal to-2 }, the human body feels cool, sets up air-out mode on the lower air inlet, reduces compressor frequency, reduces the amount of wind, adjusts the air-out angle.
For another example: under the heating mode, when { PMV is less than or equal to-2 }, a human body feels cool, an upper air inlet and lower air outlet mode is set, the frequency of a compressor is increased, the air quantity is increased, and the air outlet angle is adjusted.

Still further optionally, the controlling the operation parameters of the air conditioner in steps S120 may further include: and a third stage of controlling the operation parameters of the air conditioner in stages.
The following further describes a specific process of the third stage of controlling the operation parameters of the air conditioner in steps in step S120 with reference to a flowchart of an embodiment of the third stage of controlling the operation parameters of the air conditioner in steps in the method of the present invention shown in fig. 4, and may include: step S410 and step S420.

Wherein, under the current mode of operation is the refrigeration mode, the first air-out mode of setting for is by lower air outlet air inlet, upper air outlet air-out. When the current operation mode is the heating mode, the first set air outlet mode is air inlet from the upper air outlet and air outlet from the lower air outlet.
Therefore, the operation parameters meeting the sleep requirements of different users can be set according to different comfort requirements of different users by operating according to the target temperature and the set operation parameters in the set sleep mode, and the operation is flexible and reliable.
In an optional example, the control unit 104 may be configured to control the operation parameters of the air conditioner in stages according to the current operation time length of the air conditioner, the current operation mode, the indoor environment temperature, and/or the PMV value of the human body if the air conditioner has entered the set sleep mode, so as to meet comfort requirements of different human bodies in the sleep mode. For example: if the air conditioner enters the set sleep mode, after the air conditioner operates for a first set time period in the set sleep mode, the operating parameters of the air conditioner are controlled in stages according to the current operating mode of the air conditioner, the indoor ambient temperature and/or the PMV value of the human body, so that the comfort requirements of different human bodies are met in the sleep mode. And of course, if the air conditioner does not enter the set sleep mode, controlling the air conditioner to operate according to the set parameters of the user. The specific function and processing of the control unit 104 are referred to in step S120.
For example: an upper and lower air outlet air conditioner and a sleep mode control method thereof can utilize temperature monitoring, time control, user PMV judgment, combine an upper and lower air supply mode, adopt a bottom large air volume air supply mode at the early sleep stage of a user, rapidly cool down, judge PMV after the user enters sleep, and combine a specific PMV value to carry out upper air supply, lower air supply and air supply air volume adjustment; the temperature of the user in the sleep state can be finely controlled, the air supply quantity and the air outlet angle of the user in the sleep state can be optimized, and the comprehensive control of the air supply mode of the refrigeration or heating mode when the user is in the sleep state can be realized.
Specifically, the air conditioner is provided with an upper air outlet and a lower air outlet. In the upper air outlet and the lower air outlet, one air outlet can be used for air inlet, and the other air outlet can be used for air outlet.
For example: the air conditioner is provided with an upper air outlet and a lower air outlet, and can adopt an upper air outlet mode or a lower air outlet mode according to different requirements; therefore, through the up-down air supply air conditioner, corresponding parameters such as an up-down air outlet mode, air quantity, an air outlet angle and temperature are adjusted in real time, the indoor environment can be guaranteed to rapidly reach the parameters required by a user in a sleeping state, and the comfort level of the user is met.

The heat exchanger is composed of two rows or a plurality of rows of heat exchange tubes, and the whole heat exchanger is a cylindrical or square heat exchanger. The fan includes two axial fan, can realize air-out under the air-out, the heating mode in the refrigeration mode, and the user also can realize air-out under the refrigeration mode and air-out on the heating mode through setting up by oneself. The fan can realize air volume adjustment by controlling the fan rotating speed, the fan running quantity and the fan steering. The fan is installed inside the air supply duct.

In the cooling mode, when the user sets corresponding parameters but does not enter the sleep mode, the system performs corresponding parameter setting operation according to the set temperature value.
For another example: after the air conditioner is started to operate, when a user sets an operation sleep mode and a heating mode, an air supply mode is set to be an upper air inlet mode and a lower air outlet mode, and the air conditioner operates according to a preset temperature reference value T0And setting parameters such as fan rotating speed, fan operation quantity and the like to adjust air quantity. In the heating mode, when the user sets corresponding parameters but does not enter the sleep mode, the system performs corresponding parameter setting operation according to the set temperature value.
The control unit 104 may be further specifically configured to determine whether a temperature difference between the indoor ambient temperature and the target temperature is greater than a set temperature threshold value if the current operation duration of the air conditioner in the set sleep mode has reached a first set duration, that is, if the air conditioner has operated in the set sleep mode for the first set duration. The specific functions and processes of the control unit 104 are also referred to in step S220.
The control unit 104 may be further configured to perform a first setting adjustment on an operation parameter of the air conditioner according to a current operation mode of the air conditioner if a temperature difference between the indoor ambient temperature and the target temperature is greater than a set temperature threshold. And if the temperature difference between the indoor environment temperature and the target temperature is smaller than the set temperature threshold, performing second setting adjustment on the operation parameters of the air conditioner according to the current operation mode of the air conditioner. Of course, if the temperature difference between the indoor ambient temperature and the target temperature is equal to the set temperature threshold, the operation parameters of the air conditioner are controlled to keep the original state operation. The specific function and processing of the control unit 104 are also referred to in step S230.
Therefore, under the condition that the current operation time of the air conditioner in the set sleep mode reaches the first set time, the corresponding setting adjustment is carried out on the operation parameters of the air conditioner according to the condition that the temperature difference value between the indoor environment temperature and the target temperature is greater than or less than the set temperature threshold value, so that the operation parameters of the air conditioner are adjusted in time according to the condition of the indoor environment temperature, the comfort experience of a user is better improved, and the user can sleep in a more comfortable environment.

Or, the control unit 104 may be specifically configured to change the first set air outlet mode in the heating mode by changing a direction of a fan of the air conditioner if the current operation mode of the air conditioner is the heating mode, so as to change an air outlet mode of the air conditioner from air inlet at the upper air outlet and air outlet at the lower air outlet to air inlet at the lower air outlet and air outlet at the upper air outlet; and reducing the first set fan speed in the heating mode and/or reducing the first set fan operation number in the heating mode. The first set air outlet mode in the cooling mode may be the same as or different from the first set air outlet mode in the heating mode.

Since the processes and functions implemented by the apparatus of this embodiment substantially correspond to the embodiments, principles and examples of the method shown in fig. 1 to 4, the description of this embodiment is not detailed, and reference may be made to the related descriptions in the foregoing embodiments, which are not repeated herein.
Through a large number of tests, the technical scheme provided by the invention has the advantages that by detecting the PMV value of the human body, selecting the air supply mode according to different PMV values, adjusting the air outlet mode and the air outlet angle, quickly adjusting the temperature, realizing the fine temperature control of the user in a sleeping state, and improving the comfortable experience of the user.
According to an embodiment of the present invention, there is also provided an air conditioner corresponding to a control device of the air conditioner. The air conditioner may include: the control device of the air conditioner described above.
In some schemes, the sleeping state of the user can be judged by using data collected by the millimeter wave radar, and the air supply mode of the air conditioner is controlled according to the sleeping state; the sleep mode can be started and the temperature can be set according to the indoor illumination intensity and the current time. However, because the air outlet mode of the air conditioner in these schemes is fixed, when the user is in a sleep state, it takes too long to reach the setting parameters in the sleep state, and when the comfort requirements of different users are greatly different, the preset parameters of the air conditioner cannot meet the requirements.
That is, some air conditioners have a sleep mode in which temperature adjustment is basically performed for a preset time, for example: in the refrigeration mode, after the operation is carried out for 1h, the set temperature is automatically increased by 1 ℃, the operation is carried out for 1h, the set temperature is increased by 1 ℃ again, and the comfort of a user in a sleep state can not be really met in the operation. However, in summer, the user sets the temperature to be low before falling asleep, and after the user enters a sleep state, the user's comfort is greatly reduced according to the conventional control method. The scheme of the invention provides an upper and lower air outlet air conditioner and a sleep mode control method thereof, which can utilize temperature monitoring, time control and user PMV judgment, combine an upper and lower air supply mode, adopt a bottom large air volume air supply mode at the initial sleep stage of a user, quickly cool down, judge PMV after the user goes to sleep, and combine a specific PMV value to carry out upper air supply, lower air supply and air supply air volume adjustment; the temperature of the user in the sleep state can be finely controlled, the air supply quantity and the air outlet angle of the user in the sleep state can be optimized, and the comprehensive control of the air supply mode of the refrigeration or heating mode when the user is in the sleep state can be realized.
In an optional example, the scheme of the invention provides an air conditioner with an upper air supply mode and a lower air supply mode, wherein the air conditioner is provided with an upper air outlet and a lower air outlet, and the upper air outlet or the lower air outlet mode can be adopted according to different requirements; therefore, through the up-down air supply air conditioner, corresponding parameters such as an up-down air outlet mode, air quantity, an air outlet angle and temperature are adjusted in real time, the indoor environment can be guaranteed to rapidly reach the parameters required by a user in a sleeping state, and the comfort level of the user is met.
Optionally, according to the scheme of the invention, the PMV value of a human body can be detected, the air supply mode is selected according to different PMV values, the air outlet mode and the air outlet angle are adjusted, the temperature is quickly adjusted, and the comfort level is met.
Optionally, in the scheme of the invention, the temperature is adjusted according to the specific sleeping time of the user.

Optionally, the upper and lower air outlets may be adjusted according to corresponding air supply manners, when the upper portion is supplied with air, the lower portion is an air outlet, and when the lower portion is supplied with air, the upper portion is an air outlet.

In the cooling mode, when the user sets corresponding parameters but does not enter the sleep mode, the system performs corresponding parameter setting operation according to the set temperature value.
Step 12, when the running time t is up0Then, the infrared sensor detects the indoor average temperature T1And making corresponding temperature judgment, when the judgment condition { T } is satisfied1-T0＞△T1Adjusting the direction of the fan, and changing the direction into upper air supply and lower air outlet, increasing the rotating speed of the fan and increasing the air quantity; when the determination condition { T } is satisfied1-T0＜△T1And keeping the rotation direction of the fan unchanged, reducing the running quantity or the rotating speed of the fan and reducing the air quantity.

The average evaluation index can be predicted, and the index takes a basic equation of human body heat balance and the grade of psychophysiology subjective thermal sensation as a starting point and takes the comprehensive evaluation index of a plurality of relevant factors of human body thermal sensation and comfort sensation into consideration.
For example: the PMV index represents the comfortable feeling of most people in the same environment, and the influence parameters comprise the following parameters according to the calculation formula: clothing thermal resistance, human body metabolic rate, mechanical work done by a human body, relative humidity, wind speed, air temperature and average radiation temperature; the three parameters of the thermal resistance of the garment, the metabolic rate of the human body and the mechanical work done by the human body can be determined artificially, the relative humidity and the wind speed can be monitored by an air conditioner, and the air temperature and the average radiation temperature are acquired by an infrared sensor so as to calculate the PMV value; this part does not actually need to be described in detail in the patent writing, because the patent focuses on control after PMV determination, and does not focus on how to implement PMV determination.
For example: when { | PMV | < 2}, the air-out mode remains unchanged, i.e. the air-out mode is controlled according to the upper air-out or lower air-out set by the user, and is adjusted by the frequency modulation rate and the air-out angle, and the range can be further refined, for example, (-2, -1), [ -1, 1], (1, 2).
