Example 1
As shown in fig. 1, in this embodiment, a control method for an air conditioner is provided, which is suitable for an air conditioner with a lower air outlet or an air outlet with a lower air outlet or both an upper air outlet and a lower air outlet. The control method comprises the following steps: when the air conditioner enters a heating mode, the following control processes are executed:
detecting the indoor environment temperature and the outdoor environment temperature and recording the operation time of the air conditioner;
when the air conditioner running time reaches the preset recording time, judging whether the preset adjusting condition is met, wherein: when preset adjusting conditions are met, the air outlet direction of the lower air outlet is adjusted to the optimal air outlet direction, and the air conditioner internal unit fan is controlled to heat by combining the current gear of the air conditioner internal unit fan; when the preset adjusting condition is not met, the current running state of a fan of an air conditioner internal unit is kept, and the control process is executed again after the running time of the air conditioner is cleared;
wherein the preset adjusting conditions comprise: the current outdoor environment temperature is less than or equal to a first preset temperature, and the set temperature of the air conditioner, namely the current indoor environment temperature, is greater than or equal to a preset temperature difference.
The optimal air outlet direction is as follows: when the power of the air conditioner is fixed, the air conditioner has the most smooth air outlet position corresponding to the air deflector with the largest air outlet volume. Generally, when the air deflector in the air sweeping component swings to a middle position, namely the air deflector does not shield the air outlet as much as possible, the resistance received when the air volume is blown out is the minimum, and the air volume can be blown out to the maximum extent. The air outlet at the position is most smooth, and the maximum air outlet quantity can be ensured when the throttling effect of the air deflector at the position of the lower air outlet is the worst.

In addition, when the air conditioner is also provided with an upper air outlet positioned above the lower air outlet, namely an upper air outlet and a lower air outlet, a lower fan corresponding to the lower air outlet and an upper fan corresponding to the upper air outlet are also arranged in the fan of the air conditioner internal unit. At this moment, improve the rotational speed of air conditioner internal unit fan, can be: and increasing the rotating speed of the lower fan, or simultaneously increasing the rotating speeds of the upper fan and the lower fan. The rotating speed is increased, so that the air supply distance and the air quantity are prolonged.

This air-out mode of air outlet includes on should adjusting: and adjusting deflection of an air deflector of the upper air outlet, throttling the upper air outlet, or continuously sweeping air, namely directly reducing the air quantity of the upper air outlet or reducing the total air quantity in a certain air sweeping period. The mode utilizes the air quantity generated by the air conditioner in the working process to be constant, and realizes the increase of the air quantity distributed to the lower part in the working area of the air conditioner by changing the air quantity distribution of the upper air outlet and the lower air outlet. It should be noted that when the air deflector is adjusted, the adjustment is performed in cooperation with the increase of the rotating speeds of the upper fan and the lower fan, and as the hot air rises, the air quantity of the lower air outlet needs to be distributed more, and at the moment, the air quantity and the air speed of the lower air outlet are both increased, so that the heat exchange effect of the lower part is ensured; in addition, although the air output of the upper air outlet is reduced, the air consumption requirement of the upper part in the working area of the air conditioner can be met, the rotating speed of the upper fan is increased, the air supply distance is prolonged, and the heat exchange effect in the upper area is more obvious.
In some alternative implementations, controlling an air conditioner indoor unit fan in combination with a current gear of the air conditioner indoor unit fan includes:
judging whether the current gear is lower than a middle gear of a fan of an indoor unit of the air conditioner;
if so, increasing the gear of the wind shield of the fan of the indoor unit of the air conditioner to a middle gear; and if not, increasing the rotating speed of the fan of the air conditioner indoor unit.
Further, for the air conditioner with a lower air outlet and an upper air outlet, the fan of the air conditioner internal unit specifically comprises a lower fan corresponding to the lower air outlet and an upper fan corresponding to the upper air outlet,
when the rotating speed of the fan of the air conditioner indoor unit is increased, the rotating speed of the lower fan can be increased, or the rotating speeds of the upper fan and the lower fan can be increased simultaneously. The control method in this implementation further includes: after judging that the current gear is the highest gear of the fan of the air conditioner internal unit, the air outlet of the upper air outlet is adjusted to ensure that the air quantity distributed to the lower air outlet is increased when the total air outlet quantity of the air conditioner is unchanged. The mode can also satisfy the air-using heat exchange requirement of the upper part and the lower part in the working area of the air conditioner based on the adjustment of the air deflector and the rotating speed of the fan, and the experience effect of a user is improved.
In some optional manners, the control method further includes: in the control execution process, when the air conditioner is switched to a non-heating mode or is turned off in response to the operation of a user, the running time of the air conditioner is cleared and is not recorded any more; when the air conditioner is switched to the heating mode again in response to the user's operation, the above-described control process is re-executed.

When the air conditioner enters the heating mode, the detection of the indoor ambient temperature T1, the outdoor ambient temperature T2, and the air conditioner operation time T1 is started.
When the air conditioner running time T1 reaches the recording time delta T, whether the current time T2 is equal to or less than a first preset temperature and whether T-T1 is equal to or more than delta T is judged. Wherein the first preset temperature may be: the value of 5 ℃ or 3 ℃ is not limited and can be determined according to the actual conditions of different types of systems.
Further, if preset adjusting conditions are met, the air deflector in the lower air inlet air sweeping component moves to the most smooth air outlet position (the position corresponding to the air deflector in the best air outlet direction), and the gear of the current air conditioner indoor unit fan is judged, if the current gear is below the highest gear, the gear of the air conditioner indoor unit fan is unchanged, and if the current gear of the air conditioner indoor unit fan is the highest windshield, the rotating speed of the current air conditioner indoor unit fan is increased. The number of revolutions when the rotational speeds of the two fans are increased may be the same or different.
It should be noted that the gear of the air conditioner internal unit fan can be set to be the same gear as the upper fan and the lower fan, and the judgment and adjustment can be performed at the same gear, or the judgment can be performed only according to the gear of the lower fan in the air conditioner internal unit fan. When only the gear of the lower fan is judged, if the gear of the lower fan is the highest gear, the rotating speed is increased, namely the rotating speed of the lower fan is increased, and the gear is increased, namely the gear of the lower fan is increased.
Furthermore, in alternative implementations, it may also be: if the preset adjusting condition is met, the lower air outlet wind sweeping component moves to the most smooth air outlet position (the position corresponding to the air deflector in the best air outlet direction), and the current gear of the fan of the indoor unit of the air conditioner is judged, if the current gear is lower than the middle wind gear, the gear of the fan of the indoor unit of the air conditioner is lifted to the middle wind gear, and if the current gear is the middle wind gear or higher, the rotating speed of the fan of the indoor unit of the air conditioner is increased.
Correspondingly, if the preset adjusting condition is not met, the air conditioner keeps the gear of the fan of the air conditioner internal unit set by a customer and operates normally.
After completion of one cycle (i.e., reaching the recording time Δ T), the air conditioner operation time T1 is reset, and the control process is executed again, and so on.
When the user switches the mode to not perform heating or shut down, the air conditioner running time T1 is directly cleared and is not recorded, and when the user enters the heating mode again, the control process is executed again, and the recording of the air conditioner running time T1 is started.

After the air conditioner enters a heating mode:
the method comprises the steps of firstly, detecting indoor environment temperature T1 and outdoor environment temperature T2, and recording air conditioner running time T1.
And step two, when the operation time T1 of the air conditioner reaches 20min, judging whether the outdoor environment temperature T1 at the current moment is less than or equal to 5 ℃, and whether the difference value between the set temperature T1 of the air conditioner and the indoor environment temperature T1 is more than or equal to the preset temperature difference delta T3 ℃.
And step three, if the judgment condition in the step two is met, the air deflector in the lower air outlet wind sweeping component moves to the most smooth air outlet position (the position corresponding to the air deflector in the best air outlet direction), and the gear of the fan of the indoor unit of the air conditioner is judged, if the current gear is not the highest wind gear, the set state of a user is kept unchanged, and if the current gear is the highest gear, the rotating speed of the fan of the indoor unit of the air conditioner is increased by 30 revolutions. Or: in another control situation, if the judgment condition in the second step is met, the air deflector in the air sweeping component of the lower air outlet moves to the most smooth air outlet position (the position corresponding to the air deflector in the best air outlet direction), and the current gear of the fan of the indoor unit of the air conditioner is judged, if the current gear of the fan of the indoor unit of the air conditioner is below the middle wind gear, the gear of the fan of the indoor unit of the air conditioner is lifted to the middle wind gear, and if the current gear is at or above the middle wind gear, the rotating speed of the fan of the indoor unit of the air conditioner is increased by.
And if the judgment condition in the step two is not met, the air conditioner keeps the gear set by the customer and operates normally.
After each judgment, the air conditioner running time T1 is reset to zero, and after the air conditioner continues to run for 20min (the time length of one recorded time is finished again), the judgment is carried out again.
In addition, in the third step, the air quantity of the upper air outlet can be controlled by adjusting the air deflector of the upper air outlet, when the air outlet sectional area of the upper air outlet is reduced, the air quantity of the lower air outlet is increased when the total air quantity is constant, and the effects of increasing the air supply distance and the heat exchange quantity of the lower air outlet can also be achieved. The total heat exchange quantity of the air conditioner is not changed, although the heat exchange quantity of the upper air outlet is reduced, the temperature rise effect above a room can be ensured by utilizing the fact that a part of air quantity sent out by the lower air outlet rises and the conveying distance is longer.
Exemplary embodiments of the present disclosure are specifically illustrated and described above. It is to be understood that the present disclosure is not limited to the precise arrangements, instrumentalities, or instrumentalities described herein; on the contrary, the disclosure is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
