And S4, if the air conditioner is in the execution stage, judging the current process of the air conditioner according to the indoor environment temperature, and adjusting the frequency of the compressor, the wind shield of the cross-flow fan and the wind guide angle of the wind deflector according to the current process of the air conditioner.
According to the control method of the air conditioner, a comfortable indoor temperature environment can be provided, a comfortable indoor wind feeling environment can be provided, and the comfort of a user is improved.
In one embodiment of the present invention, when the air conditioner is cooling, the judging the no-wind-feeling stage of the air conditioner according to the indoor environment temperature and the indoor environment humidity includes: judging whether the indoor environment temperature is less than or equal to a first preset temperature and the indoor environment humidity is less than or equal to a first preset humidity; if the indoor environment temperature is less than or equal to the first preset temperature and the indoor environment humidity is less than or equal to the first preset humidity, judging that the air conditioner is in an execution stage; and if the indoor environment temperature is greater than the first preset temperature, or the indoor environment humidity is greater than the first preset humidity, judging that the air conditioner is in a preparation stage, wherein the first preset temperature is greater than a preset target temperature.
In this embodiment, the air conditioner is judged to be in the execution stage if and only if the indoor ambient temperature and the indoor ambient humidity simultaneously satisfy the condition, thereby preventing the user's comfort from being affected by the indoor ambient temperature and the indoor ambient humidity being too high or too low.
In one embodiment of the present invention, as shown in fig. 4, the execution phase includes a first process, a second process and a third process, wherein if the indoor ambient temperature is less than or equal to a first preset temperature, the air conditioner is controlled to enter the first process; after the air conditioner enters the first process, if the indoor environment temperature reaches a second preset temperature, controlling the air conditioner to enter the second process, wherein the second preset temperature is lower than the first preset temperature; and after the air conditioner enters the second process, if the indoor environment temperature reaches a third preset temperature, controlling the air conditioner to enter the third process, wherein the third preset temperature is lower than the second preset temperature.
Optionally, when the air conditioner is used for refrigerating, the second preset temperature is 2 ℃ lower than the first preset temperature, the third preset temperature is 2 ℃ lower than the second preset temperature, if the second preset temperature is 23 ℃, the first preset temperature is 25 ℃, the third preset temperature is 21 ℃, and the indoor temperature is sequentially reduced by 2 ℃ until the indoor temperature meets the temperature requirement of a user.
In one example, referring to fig. 4, 5(a) -5 (d), before the air conditioner enters the first process, the air guiding angle of the air guiding plate B is adjusted to be a first preset angle; when the air conditioner enters a first process, controlling the compressor to operate at a first preset frequency, controlling the cross-flow fan M1 and a first wind shield to operate, and adjusting the wind guide angle of a wind guide plate B to a second preset angle, wherein the first preset frequency is less than or equal to a preset target frequency, and the second preset angle is less than the first preset angle; when the air conditioner enters a second process, controlling the compressor to operate at a second preset frequency, controlling the cross-flow fan M1 and a second wind shield to operate, and adjusting the wind guide angle of the wind guide plate B to a third preset angle, wherein the second preset frequency is smaller than the first preset frequency, the second wind shield is smaller than the first wind shield, and the third preset angle is smaller than the second preset angle; and when the air conditioner enters a third process, controlling the compressor to operate at a third preset frequency, controlling the cross-flow fan M1 and a third wind shield to operate, and adjusting the wind guide angle of the wind guide plate B to a fourth preset angle, wherein the third preset frequency is smaller than the second preset frequency, the third wind shield is smaller than the second wind shield, and the fourth preset angle is smaller than the third preset angle.
In the example, when the air conditioner enters the first process, the second process and the third process, the operating frequency of the compressor, the wind gear of the cross-flow fan and the wind guide angle of the wind guide plate in each process are different, and when the air conditioner refrigerates, the operating frequency of the compressor is sequentially reduced, the wind gear of the cross-flow fan is sequentially reduced, and the wind guide angle of the wind guide plate is sequentially reduced, so that the indoor temperature and the indoor wind speed gradually change in an increasing or decreasing trend rather than in an abrupt change, and the temperature and the wind speed of the indoor environment can meet the requirements of users.
In one embodiment of the present invention, when the air conditioner is in the first process and the indoor ambient temperature reaches the second preset temperature, if the duration of the first process is less than the first preset time, the frequency of the compressor M1 is adjusted according to the indoor ambient temperature and the second preset temperature; when the air conditioner enters the second process and the indoor ambient temperature reaches the third preset temperature, if the duration of the second process is less than the second preset time, the frequency of the compressor M1 is adjusted according to the indoor ambient temperature and the third preset temperature.
Alternatively, when the air conditioner is used for cooling, the second preset temperature may be 23 ℃, and the first preset time and the second preset time may be 20 minutes. In the first process, the air conditioner enters the second process after the indoor temperature reaches 23 ℃ and is maintained for 20 minutes, if the air conditioner enters the first process and the indoor environment temperature reaches 23 ℃, but the duration of the first process is less than 20 minutes, the frequency of the compressor is adjusted according to the indoor environment temperature and 23 ℃ until the first process enters the second process when the duration of the first process is 20 minutes, the duration of the second process can also be 20 minutes, and in the second process, the indoor temperature should be less than 27 ℃, so that serious discomfort of a user caused by overhigh temperature is avoided.
Therefore, the first process and the second process of the air conditioner are carried out more fully, the non-wind-sensing mode of the air conditioner is favorably realized, and the comfort of a user is improved.
In an embodiment of the present invention, referring to fig. 6(a) and 6(b), when the air conditioner enters the third process, the swing blade E of the air conditioner is further controlled to swing from the first angle to the second angle, wherein the first angle is smaller than the second angle.
Specifically, when the air conditioner enters the third process, namely the last stage of the no-wind-sensation execution stage, the swinging blade of the air conditioner is controlled to swing from the first angle to the second angle, and the swinging blade angle of the air conditioner is increased. Therefore, the air speed of the air outlet of the air conditioner is further reduced, and the whole air conditioner enters a no-wind-sense mode.
In one embodiment of the present invention, the control method of the air conditioner further includes: when the air conditioner exits from the no-wind-sense mode, if a wind gear adjusting instruction is received, acquiring a wind gear corresponding to the wind gear adjusting instruction, and acquiring a current wind gear of the cross-flow fan; and if the current wind shield is not equal to the wind shield corresponding to the wind shield adjusting instruction, controlling the wind shield of the cross-flow fan to be increased or decreased in a stepwise manner until the wind shield corresponding to the wind shield adjusting instruction is reached.
When the user presses the non-wind-sensing key on the remote controller in the process that the air conditioner operates in the non-wind-sensing mode, the air conditioner exits the non-wind-sensing mode, and the user can input a wind gear adjusting instruction through the remote controller.
In one example, if the user inputs a damper adjustment command for strong wind and the current damper of the crossflow blower is a 20% damper when the air conditioner exits the no-wind mode, the crossflow blower damper is ramped up from 20% to 40% and then 60% and 80% at a rate until strong wind is achieved.
Therefore, the wind shield of the cross-flow fan is increased or reduced in a stepped manner, and the phenomenon that cold wind or hot wind blows to the body of a user instantly to cause severe discomfort of the user due to sudden increase or reduction of the wind shield strength is avoided.
In an embodiment of the present invention, the control method when the air conditioner performs cooling further includes: when the air conditioner enters the no-wind-sensation mode, if the indoor environment temperature is higher than a fifth preset temperature or the indoor environment humidity is higher than a second preset humidity, the air conditioner is controlled to exit the no-wind-sensation mode, wherein the fifth preset temperature is higher than the first preset temperature, and the second preset humidity is higher than the first preset humidity.
Specifically, in the process that the air conditioner enters the no-wind mode, the temperature sensor and the humidity sensor detect the indoor environment temperature and the indoor environment humidity in real time and display the indoor environment temperature and the indoor environment humidity on a display screen of the air conditioner or a screen of a remote controller, and if the indoor environment temperature is higher than a fifth preset temperature or the indoor environment humidity is higher than a second preset humidity, the air conditioner is controlled to exit the no-wind mode and send corresponding voice prompts, for example, "the indoor temperature is too high, the no-wind mode exits", so that a user receives the exit reason prompt of the air conditioner and performs corresponding control.
Therefore, the phenomenon that users feel uncomfortable due to overlarge temperature is avoided, and the reliability problems of condensation or water dripping of the air conditioner and the like due to overlarge humidity are also avoided.
In summary, the control method of the air conditioner according to the embodiment of the present invention determines the no-wind-feeling stage of the air conditioner according to the indoor environment temperature and the indoor environment humidity, and performs corresponding control and adjustment, so that the air conditioner can provide a comfortable indoor temperature environment and a comfortable indoor wind-feeling environment, thereby implementing the no-wind-feeling mode of the air conditioner, and further improving the comfort of the user.
Further, the present invention also proposes a computer-readable storage medium having stored thereon a computer program which, when executed by a processor, is capable of implementing the control method of the air conditioner of the present invention.
The computer-readable storage medium of an embodiment of the present invention, when a program stored thereon corresponding to the control method of the air conditioner described above is executed, can provide a comfortable indoor temperature environment and an indoor wind sensation environment.
