The distance detection device is used for detecting the distance between a user and the air conditioner, namely the user distance. Here, this embodiment is not intended to limit the distance detection device, and the distance detection device enumerated above is a preferred distance detection device of this embodiment.
Specifically, after the air conditioner is started, the air conditioner can be controlled to enter an intelligent air regulation mode through the control terminal, and when the air conditioner enters the intelligent air regulation mode, the human-computer distance, namely the user distance, of a human body in a monitoring area can be obtained through the distance detection device. The distance detection device can acquire the human-computer distance of a human body in a monitoring area in real time and can also acquire the human-computer distance at regular time. When the man-machine distance is acquired in real time, the air conditioner can be adjusted in real time, and when the man-machine distance is acquired in timing, the air conditioner can be adjusted in timing.
In addition, the air conditioner can be controlled to carry out a quick cooling/heating mode when the air conditioner receives a starting instruction. After the preset time, the air conditioner can be controlled to jump from the quick cooling/heating mode to the intelligent air adjusting mode, and the air conditioner can be controlled to enter the intelligent air adjusting mode from the quick cooling/heating mode when the detected ambient temperature reaches the preset temperature.
When a plurality of users exist in the monitoring area, the average human-computer distance of the plurality of users may be used as the distance, the target rotating speeds of the first wind wheel and the second wind wheel are determined according to the average human-computer distance, and the minimum or maximum human-computer distance in the human-computer distances corresponding to the plurality of users may also be used as the distance, so that the target rotating speeds of the first wind wheel and the second wind wheel are determined according to the minimum or maximum human-computer distance.
It should be noted that the preset time period may be 5 minutes, and the preset temperature may be a target temperature for cooling/heating of the air conditioner set by a user. The air conditioner firstly enters a quick cooling/heating mode when being started, the technical problem that in the prior art, when the air conditioner works in a large space, the time for presetting the temperature adjusting effect is long is solved, and the aim of quickly adjusting the temperature is fulfilled. And the air conditioner performs rapid cooling/heating on the working environment with the maximum power and the maximum air volume in the rapid cooling/heating mode.
In this embodiment, the user may also send a rotation speed setting instruction to the air conditioner through a control terminal, such as a remote controller, a mobile phone, or a tablet computer, where the rotation speed setting instruction includes an air supply distance setting parameter, an air volume setting parameter, or a gear setting parameter. The air supply distance setting parameter, the air volume setting parameter or the gear setting parameter correspond to the target air speed one by one, so that the target air speed can be determined according to the rotating speed setting instruction.
Step S20, respectively determining the corresponding target rotating speeds of the first wind wheel and the second wind wheel according to the air supply parameters;
in this real-time example, the air supply parameters include a user distance and a target air speed, when the user distance is obtained, a corresponding relation between a pre-stored user distance and the target air speed is obtained, the target air speed is determined according to the corresponding relation between the user distance and the air speed, and then target rotating speeds of the first wind wheel and the second wind wheel corresponding to the target air speed are obtained, wherein the larger the user distance is, the longer the air supply distance of the counter-rotating fan is.
Specifically, when the air supply directions of the first wind wheel and the second wind wheel are the same, when the user distance increases, the corresponding target wind speed increases correspondingly, and the target wind speed is in positive correlation with the target rotating speed. The distance is therefore positively correlated with the target speed of rotation. The target rotation speed increases as the user distance increases. When the user distance is greater than a preset distance, the rotating speed of the first wind wheel is greater than that of the second wind wheel; and when the user distance is smaller than or equal to the preset distance, the rotating speed of the first wind wheel is smaller than that of the second wind wheel. When the air supply directions of the first wind wheel and the second wind wheel are opposite and the first wind wheel supplies air to the air outlet, the requirement that the rotating speed of the first wind wheel is smaller than that of the second wind wheel when the distance between users is larger than a preset distance is met; and when the user distance is less than or equal to the preset distance, the rotating speed of the first wind wheel is greater than that of the second wind wheel. Wherein the preset distance may be 5 meters.
In addition, when a rotating speed setting instruction sent by the control terminal is received, an air supply distance setting parameter, an air volume setting parameter or a gear setting parameter is obtained. When the gear setting parameters are obtained, gear information is obtained, for example, the air supply gears may include 1, 2, 3, 4, and 5 gears, and the air supply distances corresponding to the gears may be 2 meters, 4 meters, 6 meters, 8 meters, and 10 meters, respectively; through air supply distance setting parameter can directly set up the air supply distance, when setting up specific air supply distance through control terminal, control terminal can directly acquire the numerical value of current input as air supply distance setting parameter also can confirm the air supply distance that corresponds through the rotation angle of knob. Wherein, the minimum precision of the air supply distance can be 0.1 meter; after the air volume setting parameter is obtained, the air volume percentage may be determined according to the air volume setting parameter, for example, the maximum air volume may correspond to 100%. And step S30, controlling the first wind wheel and the second wind wheel to operate according to the target rotating speed.
In this embodiment, after the target rotation speed is determined, the first wind wheel and the second wind wheel are controlled to operate according to the target rotation speed, so as to achieve the purpose of controlling the air supply distance.
In this embodiment, the target wind speed is determined by the distance detection device, and then the target rotating speed is determined, and then the rotating speeds of the first wind wheel and the second wind wheel are adjusted according to the target rotating speed, so that the purpose of intelligently controlling the air supply distance through the distance between the user and the air conditioner is achieved.
Further, referring to fig. 3, a second embodiment of the method for controlling an air conditioner according to the present invention, based on the first embodiment, the step S20 includes:
s21, acquiring a target wind speed corresponding to the user distance;
in this embodiment, the user distance is obtained first, wherein the user distance can detect the distance between the user and the air conditioner through a distance detection device. And when the user distance is obtained, obtaining the corresponding relation between the pre-stored distance and the target wind speed.
And step S22, calculating the corresponding target rotating speeds of the first wind wheel and the second wind wheel according to the target wind speed.
In this embodiment, the target wind speed and the target rotation speed are in one-to-one correspondence, and the correspondence relationship is stored in a storage medium, and when the target wind speed is obtained, the corresponding target rotation speed may be determined according to the target wind speed.
Specifically, when the air supply directions of the first wind wheel and the second wind wheel are the same, when the user distance increases, the corresponding target wind speed increases correspondingly, and the target wind speed is in positive correlation with the target rotating speed. The distance is therefore positively correlated with the target speed of rotation. The target rotation speed increases as the user distance increases. When the user distance is greater than a preset distance, the rotating speed of the first wind wheel is greater than that of the second wind wheel; and when the user distance is smaller than or equal to the preset distance, the rotating speed of the first wind wheel is smaller than that of the second wind wheel. When the air supply directions of the first wind wheel and the second wind wheel are opposite, and the first wind wheel supplies air to the air outlet, the requirement that the rotating speed of the first wind wheel is less than that of the second wind wheel when the user distance is greater than the preset distance is met; when the user distance is smaller than or equal to the preset distance, the rotating speed of the first wind wheel is larger than that of the second wind wheel. Wherein the preset distance may be 5 meters.
In this embodiment, the target wind speed corresponding to the distance is obtained first, and then the target rotation speed is determined according to the target wind speed, so that the distance and the target rotation speed form a one-to-one correspondence relationship.
Further, referring to fig. 4, a third embodiment of the method for controlling an air conditioner according to the present invention is based on the first to second embodiments, and the step S10 includes:
step S11, obtaining a rotating speed setting instruction sent by the control terminal;
and step S12, determining a corresponding target wind speed according to the rotating speed setting instruction.
In this embodiment, a rotation speed setting instruction may be sent to the air conditioner through a control terminal, where the control terminal may include a mobile phone, a tablet computer, a PC and/or a remote controller, and the like; and determining a gear setting parameter, an air quantity setting parameter or an air supply distance setting parameter according to the rotating speed control instruction.
Specifically, the air supply gear of the air conditioner can be set according to the gear setting parameters, and different gears can correspond to different target wind speeds.
The air volume setting parameter can be air volume percentage, and different air volume percentages can be set according to the air volume setting parameter, for example, the maximum air supply power corresponds to one hundred percent of air volume. And determining the corresponding target wind speed according to different wind volume percentages.
The air supply distance setting instruction can set the air supply distance corresponding to the parameter, and the corresponding target air speed can be determined according to the air supply distance. And the air supply gear, the air volume percentage and the air supply distance are positively correlated with the target air speed.
A target rotational speed may be determined according to the target wind speed such that the target rotational speed may be set by the rotational speed setting parameter. For example, the correspondence between the gear position and the target rotation speed may be set as follows:
the two wind wheel rotating speeds of the first gear are respectively as follows: the first wind wheel rotates at 100 rpm, and the second wind wheel rotates at 250 rpm;
the rotating speeds of the two wind wheels of the second gear are respectively as follows: the first wind wheel rotates at 200 rpm, and the second wind wheel rotates at 400 rpm;
the rotating speeds of the two wind wheels in the third gear are respectively as follows: the first wind wheel rotates at 400 rpm, and the second wind wheel rotates at 550 rpm;
the rotating speeds of the two wind wheels in the fourth gear are respectively as follows: the first wind wheel rotates at 600 rpm, and the second wind wheel rotates at 500 rpm;
the rotating speeds of the two wind wheels in the fifth gear are respectively as follows: 700 revolutions per minute of the first wind wheel and 600 revolutions per minute of the second wind wheel;
the rotating speeds of the two wind wheels in the sixth gear are respectively as follows: the first wind wheel is 800 rpm, the second wind wheel is 700 rpm.
In addition, when the air conditioner receives a starting instruction, the air conditioner can be controlled to execute a quick cooling/heating instruction to enter a quick cooling/heating mode, wherein the air conditioner performs quick cooling/heating on the working environment at the maximum power and the maximum air supply distance in the quick cooling/heating mode. And when the time for entering the rapid cooling/heating mode is longer than the preset time, executing the rotating speed setting instruction, or when the environment temperature is detected to reach the preset temperature, executing the rotating speed setting instruction.
It should be noted that the preset time period may be 5 minutes, and the preset temperature may be a cooling/heating target temperature of the air conditioner set by a user. The air conditioner is in a refrigeration/heating mode when being started, the technical problem that in the prior art, when the air conditioner works in a large space, the time for presetting the temperature regulation effect is long is solved, and the purpose of quickly regulating the temperature is achieved.
In this embodiment, a rotating speed setting instruction is obtained first, and then the rotating speeds of the first wind wheel and the second wind wheel are adjusted according to the rotating speed setting instruction, so that the purpose of setting the air supply distance of the air conditioner by setting the rotating speed of the wind wheels is achieved.
Further, referring to fig. 5, a fourth embodiment of the control method of the air conditioner according to the present invention, based on the first to third embodiments, the step S20 includes:
step S23, obtaining the ratio of the number of the blades of the first wind wheel and the second wind wheel;
and step S24, determining the corresponding target rotating speeds of the first wind wheel and the second wind wheel according to the air supply parameters and the blade number ratio.
