Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to specific embodiments of the present invention and corresponding drawings. It will be apparent that the described embodiments are only some, but not all, embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
According to an embodiment of the present invention, there is provided a control method of an air conditioner, as shown in fig. 1, which is a schematic flow chart of an embodiment of the method of the present invention. The control method of the air conditioner can be applied to an air conditioner which is provided with an upper air outlet and a lower air outlet and can perform an up-down air supply mode, and the control method of the air conditioner can comprise the following steps: step S110 and step S120.
At step S110, it is determined whether the air conditioner has entered a set sleep mode.
The set sleep mode may include: and controlling the air conditioner to take the first set temperature as the target temperature, and adjusting the air quantity according to the first set air mode, the first set fan rotating speed and/or the first set fan running quantity. And when the current operation mode is a refrigeration mode, the first air setting mode is air inlet from the lower air outlet and air outlet from the upper air outlet. And under the condition that the current operation mode is a heating mode, the first set air-setting mode is air inlet from the upper air outlet and air outlet from the lower air outlet.
Therefore, the operation parameters meeting the sleeping requirements of different users can be set according to the different comfort requirements of different users by operating according to the target temperature and the set operation parameters in the set sleeping mode, and the sleeping device is flexible and reliable.
At step S120, if the air conditioner has entered the set sleep mode, the operation parameters of the air conditioner are controlled in stages according to the current operation time length, the current operation mode, the indoor environment temperature and/or the PMV value of the human body of the air conditioner, so as to meet the 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 period of time in the set sleep mode, the operation parameters of the air conditioner are controlled in stages according to the current operation mode of the air conditioner, the indoor environment 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. Of course, if the air conditioner does not enter the set sleep mode, the air conditioner is controlled to operate according to the set parameters of the user.
For example: the upper and lower air outlet air conditioner and the sleep mode control method thereof can utilize temperature monitoring, time control, PMV judgment of a user, combine an upper and lower air supply mode, adopt a bottom large air supply mode at the initial stage of sleeping of the user, quickly cool, perform PMV judgment after the user enters sleeping, and combine specific PMV values to perform upper air supply, lower air supply and air supply air quantity adjustment; the temperature fine control of the user in the sleep state can be realized, the air supply quantity and the air outlet angle of the user in the sleep state are optimized, and the air supply mode of the refrigerating or heating mode is comprehensively controlled when the user is in the sleep state.
Specifically, the air conditioner is provided with an upper air outlet and a lower air outlet. One of the upper air outlet and the lower 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 an upper air outlet mode or a lower air outlet mode can be adopted according to different requirements; therefore, through the up-down air supply air conditioner, the up-down air outlet mode, the air quantity, the air outlet angle, the temperature and other parameters are adjusted in real time, the indoor environment is ensured to be capable of rapidly reaching the parameters required by a user in a sleep state, and the comfort level of the user is met.
For example: as shown in fig. 6, the upper air outlet and the lower air outlet can be adjusted according to the corresponding air supply mode, when the upper air is supplied, the lower air outlet is the air outlet, and when the lower air is supplied, the upper air outlet is the air outlet; the air conditioner in fig. 6 is composed of upper and lower air outlets (such as the upper air outlet 1 in fig. 6), a heat exchanger 3, a fan 5, an air supply duct and other components; and also has a lower air inlet 4. The heat exchanger is composed of double rows or multiple rows of heat exchange tubes, and the whole heat exchanger is a cylinder type or square heat exchanger. The fan comprises two axial flow fans, can realize the air-out in the refrigerating mode and the air-out in the heating mode, and can also realize the air-out in the refrigerating mode and the air-out in the heating mode through self-setting by a user. The fan can realize air quantity adjustment by controlling the rotating speed of the fan, the running quantity of the fan and the steering direction of the fan. The fan is installed inside the air supply duct.
Therefore, under the condition that the air conditioner enters a set sleep mode, the operation parameters of the air conditioner are controlled in stages according to the current operation time length, the current operation mode, the indoor environment temperature, the PMV value of a human body and the like of the air conditioner, so that the comfort requirements of different users are met, and the air conditioner is humanized.
The operation parameters of the air conditioner may include: compressor operating frequency, air-out mode, air-out volume and/or air-out angle.
Therefore, through various operating parameters, the air conditioner control accuracy and reliability can be improved.
Optionally, controlling the operation parameters of the air conditioner in stages may include: the first stage of the operating parameters of the air conditioner is controlled in stages.
The following is a flowchart of an embodiment of the first stage of the method of the present invention for controlling the operation parameters of the air conditioner in stages in the method of the present invention in conjunction with fig. 2, further describing the specific process of the first stage of controlling the operation parameters of the air conditioner in stages in step S120, which may include: step S210 to step S230.
In step S210, it is determined whether the current operation duration of the air conditioner in the set sleep mode has reached the first set duration, that is, whether the air conditioner has operated in the set sleep mode for the first set duration.
For example: after the air conditioner is started and operated, when a user sets an operation sleep mode, in a refrigeration mode, an air supply mode is set to be bottom air inlet and upper air outlet, and according to a preset temperature reference value T 0 And setting parameters such as fan rotating speed, fan running number and the like to adjust the air quantity. In the cooling mode, when the user sets the corresponding parameters, but does not enter the sleep mode, the system runs according to the set temperature value and the corresponding set parameters.
Another example is: after the air conditioner is started and operated, when a user sets an operation sleep mode and a heating mode, an air supply mode is setFor upper air inlet and lower air outlet, according to preset temperature reference value T 0 And setting parameters such as fan rotating speed, fan running number and the like to adjust the air quantity. In the heating mode, when the user sets the corresponding parameters, but does not enter the sleep mode, the system runs according to the set temperature values and the corresponding set parameters.
In step S220, if the current operation duration of the air conditioner in the set sleep mode has reached the first set duration, that is, if the air conditioner has operated in the set sleep mode for the first set duration, it is determined whether the temperature difference between the indoor environment temperature and the target temperature is greater than the set temperature threshold.
Step S230, if the temperature difference between the indoor environment temperature and the target temperature is greater than the set temperature threshold, the operation parameters of the air conditioner are first set and adjusted 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 environment 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 operation parameters of the air conditioner are correspondingly set and adjusted according to the condition that the temperature difference between the indoor environment temperature and the target temperature is larger or smaller than the set temperature threshold, so that the operation parameters of the air conditioner are timely adjusted according to the condition of the indoor environment temperature, the comfort experience of a user is better improved, and the user can enter sleep in a more comfortable environment.
More optionally, the first setting adjustment of the operation parameters of the air conditioner according to the current operation mode of the air conditioner in step S230 may include: if the current running mode of the air conditioner is a refrigerating mode, changing a first set air-setting mode in the refrigerating mode by changing the direction of a fan of the air conditioner so as to change the air-out mode of the air conditioner from the air-in mode of a lower air outlet to the air-out mode of an upper air outlet; and increasing the first set fan speed in the refrigeration mode and/or increasing the first set fan operation number in the refrigeration mode. Or if the current running mode of the air conditioner is a heating mode, changing the first set air-setting mode under the heating mode by changing the direction of a fan of the air conditioner so as to change the air-out mode of the air conditioner from the air-in mode of an upper air outlet to the air-out mode of a lower air outlet to the air-in mode of a lower air outlet; and reducing the rotating speed of the first set fan in the heating mode and/or reducing the running number of the first set fan in the heating mode. The first setting air mode in the cooling mode may be the same or different from the first setting air mode in the heating mode.
For example: in the cooling mode, when the operation time t 0 After that, the infrared sensor detects the indoor average temperature T 1 And corresponding temperature judgment is carried out, when the judgment condition { T } is satisfied 1 -T 0 ＞△T 1 And adjusting the steering of the fan, changing the upper air supply into the lower air supply, increasing the rotating speed of the fan and increasing the air quantity.
Another example is: in heating mode, when the operation time t 0 After that, the infrared sensor detects the human body temperature value T 1 And corresponding temperature judgment is carried out, when the judgment condition { T } is satisfied 1 -T 0 ＞△T 1 And the steering of the fan is changed into lower air inlet and upper air outlet, the running number 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 a refrigeration mode, and the air outlet quantity is increased, so that the indoor environment temperature can be improved more quickly; the air outlet mode of the air conditioner is changed in the heating mode, the air outlet quantity is reduced, and the indoor environment temperature can be improved more quickly, so that the adjusting efficiency of the air conditioner is improved more efficiently and accurately, and the comfort feeling of a user is improved.
More optionally, the second setting adjustment of the operation parameters of the air conditioner according to the current operation mode of the air conditioner in step S230 may include: if the current running mode of the air conditioner is the refrigerating mode, controlling the air conditioner to output air according to a first set air mode in the refrigerating mode, and reducing the rotating speed of the first set fan in the refrigerating mode and/or reducing the running number of the first set fans in the refrigerating mode. Or if the current running mode of the air conditioner is the heating mode, controlling the air conditioner to still perform air volume adjustment according to the first set fan rotating speed and/or the first set fan running number in the heating mode.
For example: in the cooling mode, when the operation time t 0 After that, the infrared sensor detects the indoor average temperature T 1 And corresponding temperature judgment is carried out, when the judgment condition { T } is satisfied 1 -T 0 ＜△T 1 And the steering of the fans is kept unchanged, the running number of the fans or the rotating speed of the fans is reduced, and the air quantity is reduced.
Another example is: in heating mode, when the operation time t 0 After that, the infrared sensor detects the human body temperature value T 1 And corresponding temperature judgment is carried out, when the judgment condition { T } is satisfied 1 -T 0 ＜△T 1 And keeping the upper air inlet and the lower air outlet of the fan, and adjusting the air quantity.
Therefore, 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 maintained in a refrigeration mode, and the air outlet quantity is reduced; the air outlet mode of the air conditioner is kept under 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, controlling the operation parameters of the air conditioner in stages in step S120 may further include: and controlling the second stage of the operation parameters of the air conditioner in stages.
The following is a schematic flow chart of an embodiment of the second stage of controlling the operation parameters of the air conditioner in stages in the method of the present invention in connection with fig. 3, which further illustrates a specific process of the second stage of controlling the operation parameters of the air conditioner in stages in step S120, and may include: step S310 and step S320.
Step S310, after the second set duration is set and adjusted for the operation parameters of the air conditioner according to the current operation mode of the air conditioner or the third set duration is set and adjusted for the operation parameters of the air conditioner according to the current operation mode of the air conditioner, 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.
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, fourth setting and adjusting the operation parameters of the air conditioner according to the current operation mode of the air conditioner. Naturally, 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 operation parameters of the air conditioner are subjected to first setting and second setting time 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 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, fourth setting and adjusting the operation parameters of the air conditioner according to the current operation mode of the air conditioner. Naturally, 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 performing the second setting adjustment on the operation parameters of the air conditioner according to the current operation mode of the air conditioner for a third setting 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 greater than or equal to the upper limit of the set index range, fifth setting and adjusting 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 sixth set adjustment on the operation parameters of the air conditioner according to the current operation mode of the air conditioner. Naturally, 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 the PMV is less than 2, the original air supply mode is maintained, and the air quantity is regulated by combining the specific PMV value.
For example: in the refrigerating mode or heating mode, when the air conditioner operates according to the upper air outlet operation time t 1 Or run t with lower air outlet 2 And then, the infrared sensor detects the temperature of the human body and carries out PMV judgment.
Therefore, after the second set duration is set and adjusted according to the current operation mode of the air conditioner or the third set duration is set and adjusted according to the current operation mode of the air conditioner, the operation parameters of the air conditioner are controlled according to the magnitude relation between the PMV value of the human body and the set index range, so that the operation parameters of the air conditioner can be adjusted in time according to the body temperature conditions of different users more accurately, and the respective comfort feeling of different users is improved.
More optionally, the third setting adjustment 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 refrigerating mode, controlling the air conditioner to discharge air in an air discharge mode opposite to the first air setting mode in the refrigerating mode, namely controlling the air conditioner to discharge air in an air discharge mode after the first air setting mode in the refrigerating mode is changed by changing the direction of a fan of the air conditioner so as to realize that the air discharge mode of the air conditioner is changed from the air inlet of a lower air outlet to the air outlet of an upper air outlet to the air inlet of an upper air outlet; and increasing the compressor operating frequency in the refrigeration mode, increasing the first set fan rotating speed in the refrigeration mode, increasing the first set fan operating number 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, controlling the air conditioner to discharge air according to a first set air-out mode in the heating mode, reducing the operation frequency of the compressor in the heating mode, reducing the rotation speed of the first set fans in the heating mode, reducing the operation quantity of the first set fans in the heating mode, and/or reducing the air-out angle in the heating mode to reduce the air-out quantity.
For example: the third setting adjustment of the operation parameters of the air conditioner according to the current operation mode of the air conditioner or the fifth setting adjustment of the operation parameters of the air conditioner according to the current operation mode of the air conditioner may include: in the refrigerating mode, controlling the air conditioner to discharge air in an air discharge mode opposite to the first air setting mode in the refrigerating mode, namely controlling the air conditioner to discharge air in an air discharge mode after the first air setting mode in the refrigerating mode is changed by changing the direction of a fan of the air conditioner so as to realize that the air discharge mode of the air conditioner is changed from the air inlet of a lower air outlet to the air outlet of an upper air outlet to the air inlet of an upper air outlet; and increasing the compressor operating frequency in the refrigeration mode, increasing the first set fan rotating speed in the refrigeration mode, increasing the first set fan operating number in the refrigeration mode, and/or increasing the air outlet angle in the refrigeration mode to increase the air outlet quantity.

For example: the fourth setting adjustment of the operation parameters of the air conditioner according to the current operation mode of the air conditioner or the sixth setting adjustment of the operation parameters of the air conditioner according to the current operation mode of the air conditioner may include: in the refrigerating mode, the air conditioner is controlled to discharge air according to a first set air-setting mode in the refrigerating mode, the operation frequency of a compressor in the refrigerating mode is reduced, the rotation speed of the first set fans in the refrigerating mode is reduced, the operation number of the first set fans in the refrigerating mode is reduced, and/or the air-discharging angle in the refrigerating mode is reduced to reduce the air-discharging quantity. Or in the heating mode, controlling the air conditioner to discharge air in an air discharge mode opposite to the first air setting mode in the heating mode, namely controlling the air conditioner to discharge air in an air discharge mode after the first air setting mode in the heating mode is changed by changing the direction of a fan of the air conditioner so as to change the air discharge mode of the air conditioner from the lower air outlet to the upper air outlet; and increasing the operating frequency of the compressor in the heating mode, increasing the rotating speed of the first set fan in the heating mode, increasing the operating number of the first set fan in the heating mode, and/or modulating the air outlet angle in the heating mode to increase the air outlet quantity.

Still further alternatively, the step S120 of controlling the operation parameters of the air conditioner in stages may further include: and a third stage for controlling the operation parameters of the air conditioner in stages.
The following is a schematic flow chart of an embodiment of the third stage of controlling the operation parameters of the air conditioner in stages in the method of the present invention in connection with fig. 4, which further illustrates a specific process of the third stage of controlling the operation parameters of the air conditioner in stages in step S120, and may include: step S410 and step S420.

And under the condition that the current operation mode is a heating mode, the first set air-setting mode is air inlet from the upper air outlet and air outlet from the lower air outlet.
Therefore, the operation parameters meeting the sleeping requirements of different users can be set according to the different comfort requirements of different users by operating according to the target temperature and the set operation parameters in the set sleeping mode, and the sleeping device is flexible and reliable.
In an alternative example, the control unit 104 may be configured to control the operation parameters of the air conditioner in stages according to the current operation duration 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 the 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 period of time in the set sleep mode, the operation parameters of the air conditioner are controlled in stages according to the current operation mode of the air conditioner, the indoor environment 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. Of course, if the air conditioner does not enter the set sleep mode, the air conditioner is controlled to operate according to the set parameters of the user. The specific function and process of the control unit 104 refer to step S120.

The heat exchanger is composed of double rows or multiple rows of heat exchange tubes, and the whole heat exchanger is a cylinder type or square heat exchanger. The fan comprises two axial flow fans, can realize the air-out in the refrigerating mode and the air-out in the heating mode, and can also realize the air-out in the refrigerating mode and the air-out in the heating mode through self-setting by a user. The fan can realize air quantity adjustment by controlling the rotating speed of the fan, the running quantity of the fan and the steering direction of the fan. The fan is installed inside the air supply duct.
Therefore, under the condition that the air conditioner enters a set sleep mode, the operation parameters of the air conditioner are controlled in stages according to the current operation time length, the current operation mode, the indoor environment temperature, the PMV value of a human body and the like of the air conditioner, so that the comfort requirements of different users are met, and the air conditioner is humanized.

In the heating mode, when the user sets the corresponding parameters, but does not enter the sleep mode, the system runs according to the set temperature values and the corresponding set parameters.

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 environment 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 process of the control unit 104 is also referred to as 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 operation parameters of the air conditioner are correspondingly set and adjusted according to the condition that the temperature difference between the indoor environment temperature and the target temperature is larger or smaller than the set temperature threshold, so that the operation parameters of the air conditioner are timely adjusted according to the condition of the indoor environment temperature, the comfort experience of a user is better improved, and the user can enter sleep in a more comfortable environment.

In some schemes, the sleep state of a user can be judged by utilizing data collected by the millimeter wave radar, and the air supply mode of the air conditioner is controlled by the sleep state; the start-up and temperature setting of the sleep mode can also be judged by the indoor illumination intensity and the current time. However, because the air-out mode of the air conditioner is fixed in these schemes, when the user is in a sleep state, the time for setting parameters in the sleep state is too long, 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 is basically adjusted according to a preset time, for example: in the refrigeration mode, after the operation for 1h, the set temperature is automatically increased by 1 ℃, the operation is carried out for 1h again, the set temperature is increased by 1 ℃ again, and the comfort of a user in a sleeping state can not be really met in the operation. However, in summer, some users will set the temperature very low before falling asleep, and after the user enters a sleep state, if the user is controlled in the existing control manner, the comfort of the user will be greatly reduced. The scheme of the invention provides an up-down air-out air conditioner and a sleep mode control method thereof, which can utilize temperature monitoring, time control and PMV judgment of a user, combine an up-down air supply mode, adopt a bottom large air volume air supply mode at the initial stage of sleeping of the user, quickly cool down, perform PMV judgment after the user enters sleep, and combine specific PMV values to perform up-air supply, down-air supply and air supply air volume adjustment; the temperature fine control of the user in the sleep state can be realized, the air supply quantity and the air outlet angle of the user in the sleep state are optimized, and the air supply mode of the refrigerating or heating mode is comprehensively controlled when the user is in the sleep state.
