The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the present invention and should not be construed as limiting the present application.
An air conditioner and a control method and apparatus thereof according to an embodiment of the present application are described below with reference to the accompanying drawings.
It should be noted that the air conditioner includes at least two air outlets of a top air outlet, a front air outlet, and a side air outlet. The air conditioner in this embodiment may include, but is not limited to, a top outlet, a front outlet, and a side outlet.
Fig. 1 is a schematic structural diagram of an air conditioner according to an embodiment disclosed in the present application. As shown in fig. 1, the air conditioner 100 in the present embodiment includes an air conditioner body 11; an air inlet 12 is arranged at the rear side of the air conditioner body 11, and a front air outlet 13 is arranged at the front side; the upper part of the front air outlet 13 is provided with a top air outlet 14; the side of the air conditioner is provided with a side outlet (not shown in the figure). When the air conditioner 100 is started, external air enters the air conditioner 100 from the air inlet 12, and the air conditioner 100 performs cooling or heating treatment on the external air entering the air conditioner 100; further, the air treated by the driving of the fan 15 flows into the room through the front air outlet 13; when the top outlet 14 is open, the treated air will also flow into the room through the top outlet 14.
Fig. 2 is a flowchart illustrating a control method of an air conditioner according to an embodiment of the present disclosure. As shown in fig. 2, the method for controlling an air conditioner provided in this embodiment includes the following steps:
s101, detecting the state of each air outlet and acquiring the state change information of the air outlets.
Optionally, the state of the air outlet in the air conditioner is often consistent with a control command issued by a user. Therefore, the control instruction of each air outlet can be detected, and the state change information of the air outlet can be determined according to the detected control instruction and the previous state of the air outlet. The state change information may include, but is not limited to, that the state of the air outlet changes and that the state of the air outlet does not change.
For example, when it is detected that the control instruction for one of the air outlets is an opening instruction, if the state before the air outlet is a closing state, it may be determined that the state of the air outlet changes after the control instruction is received; and if the state before the air outlet is the opening state, the state of the air outlet can be determined not to change after the control instruction is received.
It should be understood that, when the control command of each air outlet is detected, the control command can be identified according to the control command received by the air conditioner. Specifically, a button for controlling the opening or closing of the air outlet may be disposed on the air conditioner, and a user may open or close the air outlet by clicking the button on the air conditioner. Optionally, the user may also issue a control instruction for opening or closing the air outlet to the air conditioner through a remote controller of the air conditioner or an application program on the terminal device, so that the controller in the air conditioner receives the control instruction issued by the user.
And S102, detecting and identifying the change of the air output of the air outlet in the air conditioner in unit area according to the detected state change information.
Optionally, when the detected state change information is that the state of the air outlet changes, the total air outlet area of the air outlet of the air conditioner; at this time, since the current total air output of the air conditioner is not changed, the air output per unit area of the air outlet in the air conditioner is changed. Therefore, when the state change information indicates that the state of the air outlet changes, the change of the air output of the air outlet in the air conditioner per unit area can be identified; and when the state change information indicates that the state of the air outlet is not changed, the air outlet volume of the air outlet in the air conditioner per unit area can be identified to be unchanged.
Optionally, whether the air output of the air outlet in the air conditioner per unit area changes may also be determined according to the air outlet areas of the air conditioner at different times. As shown in fig. 3, the method comprises the following steps:
s201, determining a first air outlet area of the air conditioner at the current moment according to the state change information.
Specifically, when the state change information indicates that the state of the air outlet changes, the first air outlet area of the air conditioner at the current moment is determined according to the preset area of each air outlet. For example, the area of outlet a is a1, the area of outlet B is a2, and the area of outlet C is A3; if the air outlets A, B and C are both open at this time, the first air outlet area of the air conditioner at the current time is a1+ a2+ A3.
S202, acquiring a second air outlet area of the air conditioner at the previous moment.
Specifically, after the first air outlet area of the air conditioner at the current moment is determined, the second air outlet area of the air conditioner at the previous moment can be obtained. For example, the area of outlet a is a1, the area of outlet B is a2, and the area of outlet C is A3; if the air outlet A is in the closed state at the previous moment and the air outlets B and C are both in the open state, the second air outlet area of the air conditioner at the previous moment is A2+ A3.
And S203, identifying that the first air outlet area is different from the second air outlet area, and determining that the air output per unit area changes.
Specifically, a first air outlet area and a second air outlet area are determined, and the first air outlet area and the second air outlet area are compared. If the first air outlet area is different from the second air outlet area, determining that the air output per unit area changes; and if the first air outlet area is the same as the second air outlet area, determining that the air output per unit area is not changed.
And S103, adjusting the rotating speed of a fan in the air conditioner.
Specifically, when it is recognized that the air output per unit area of the air outlet in the air conditioner changes, in order to keep the air output per unit area of the air outlet in the air conditioner unchanged, the total air output of the air conditioner needs to be adjusted, and therefore, the rotation speed of the fan in the air conditioner can be adjusted, so that the total air output of the air conditioner is adjusted. When the air output per unit area is identified to be increased, the rotating speed of the fan is reduced to reduce the total air output of the air conditioner so as to keep the air output per unit area of an air outlet in the air conditioner unchanged; or when the air output per unit area is identified to be reduced, the rotating speed of the fan is increased so as to increase the total air output of the air conditioner and keep the air output per unit area of the air outlet in the air conditioner unchanged.
As a possible implementation manner, at least two air outlets in the air conditioner include a top air outlet, and when the state of the top air outlet changes from a closed state to an open state (i.e., when a control instruction for opening the top air outlet is received), as shown in fig. 4, adjusting the rotation speed of the fan in the air conditioner includes the following steps:
s301, acquiring a first rotating speed of a fan in the air conditioner in the current operation.
Specifically, the rotating speed and the windshield of the fan need to be calibrated when the air conditioner leaves a factory, so that the mapping relation between the rotating speed and the windshield of the fan can be inquired according to the windshield of the air conditioner selected by a user, and the first rotating speed of the current operation of the fan is determined. The first rotating speed is the rotating speed of the fan when the top air outlet is not opened.
Optionally, a rotation speed sensor is disposed in the air conditioner, and the rotation speed of the fan may also be detected by the rotation speed sensor, which may be determined according to actual conditions, and is not limited herein.
S301, acquiring a target adjusting coefficient of the fan for adjusting the rotating speed.
Specifically, the target adjustment coefficient is used for adjusting the rotation speed of the fan, and the target adjustment coefficient may be a measured value or a calibrated value, and may be determined according to an actual situation, which is not limited herein.
Alternatively, when the target adjustment coefficient is a measured value, as shown in fig. 5, acquiring the target adjustment coefficient includes the steps of:
s401, obtaining a first adjusting coefficient of the rotating speed of the fan when the air conditioner is started for the first time.
Specifically, when the air conditioner is started for the first time, the controller in the air conditioner drives the fan to operate at a second rotating speed, and at this time, a first adjustment coefficient of the rotating speed of the fan can be obtained, wherein the second rotating speed is a preset rotating speed. The first adjusting coefficient is used for representing the correlation degree of the air outlet and the air duct damping when the air conditioner is started for the first time.
S402, obtaining a second adjusting coefficient of the rotating speed of the fan when the air conditioner opens the top air outlet for the first time.
Specifically, when the air conditioner opens the top air outlet for the first time, the controller in the air conditioner drives the fan to operate at the second rotating speed, and at the moment, the second adjusting coefficient of the rotating speed of the fan can be obtained, wherein the second adjusting coefficient is used for representing the correlation degree of the air outlet and the air duct damping when the top air outlet is opened.
In this embodiment, the determining the first or second adjustment factor according to the rotation speed of the fan and the input power of the motor in the air conditioner, as shown in fig. 6, includes the following steps:
s501, detecting and determining that the time length of the fan running at the second rotating speed reaches the preset time length, and acquiring the real-time input power of the motor in the air conditioner.
Specifically, the fan can be controlled to operate at the second rotating speed for a preset time period, so that the motor operates stably, and then the real-time input power of the motor is acquired. Alternatively, the input current and the input voltage of the motor may be detected using a current detection circuit and a voltage detection circuit, and the real-time input power of the motor may be calculated from the input current and the input voltage.
And S502, determining an adjusting coefficient for adjusting the rotating speed of the fan according to the second rotating speed and the real-time input power.
Specifically, in this embodiment, a ratio of the real-time input power to the first rotation speed is obtained, and the ratio is used as an adjustment coefficient.
It should be noted that, in this embodiment, the method for obtaining the second adjustment coefficient is the same as the method for obtaining the first adjustment coefficient, when obtaining the first adjustment coefficient, the obtained second rotation speed is the rotation speed when the air conditioner is started for the first time, and when obtaining the second adjustment coefficient, the obtained second rotation speed is the rotation speed when the air conditioner is started to eject air. Further, in this embodiment, the real-time input powers corresponding to the first adjustment coefficient and the second adjustment coefficient are different. Optionally, the first-time starting rotation speed of the air conditioner and the rotation speed when the air conditioner starts the ejection air may be the same or different, and the rotation speed is not limited herein.
And S403, determining a target adjustment coefficient according to the first adjustment coefficient and the second adjustment coefficient.
Specifically, in this embodiment, a difference between the second adjustment coefficient and the first adjustment coefficient is obtained, a ratio between the difference and the first adjustment coefficient is obtained, and the ratio is used as the target adjustment coefficient. The specific calculation formula is:
K＝(K2-K1)/K1
wherein K is a target adjustment coefficient, K1Is a first adjustment coefficient, K2Is the second adjustment factor.
And S303, adjusting the rotating speed of the fan according to the target adjusting coefficient and the first rotating speed.
Particularly, the target adjustment coefficient and the first rotating speed are obtained, the rotating speed of the fan can be adjusted according to the target adjustment coefficient and the first rotating speed, so that the total air output of the air conditioner is improved, the unit area air output of the air conditioner is maintained unchanged, the user requirement is met, and the user experience is improved.
Optionally, as shown in fig. 7, the adjusting the rotation speed of the fan includes the following steps:
s601, obtaining a product between the target adjusting coefficient and the first rotating speed, and adding the product and the first rotating speed to obtain the target rotating speed.
Specifically, when the rotation speed of the fan is adjusted, the target rotation speed of the fan needs to be obtained first, and in this embodiment, the target rotation speed is obtained through the following formula:
nt＝n+K*n
wherein n istIs a target rotation speed, n is a first rotation speed, and K is a target adjustment coefficient。
And S602, controlling the rotating speed of the fan to be adjusted to the target rotating speed from the first rotating speed.
Specifically, the target rotating speed of the air outlet machine is determined, and the rotating speed of the fan can be controlled to be adjusted to the target rotating speed from the first rotating speed.
In this embodiment, when the top air outlet is opened, the air outlet area of the air conditioner is increased, and if the fan is not changed, the air outlet amount per unit area of the air conditioner is reduced, so that the user requirements cannot be met; and when opening ejecting wind, adjust the rotational speed of fan, if increase the rotational speed to improve the total air output of air conditioner, in order to maintain the unit area air output of air conditioner unchangeable, thereby satisfied user's demand, improved user experience.
Further, after the top air outlet is opened for a certain time, when a user selects to close the top air outlet, the air outlet area of the air conditioner is reduced, and at the moment, if the rotating speed of the fan is not adjusted, the air outlet amount per unit area of the air conditioner is increased. Therefore, in order to maintain the air output per unit area of the air conditioner constant, the rotating speed of the fan can be selected to be recovered to the first rotating speed from the target rotating speed when the top air outlet is closed. Namely, when a control instruction for closing the top outlet air of the air conditioner is received through recognition, the rotating speed of the fan is controlled to be recovered to the first rotating speed from the target rotating speed.
