When the air conditioner starts to perform cooling operation, the water level in the water collecting tray gradually rises along with the generation of condensed water. When the real-time water level height of the water accumulation disc reaches a first preset height, a certain water accumulation amount exists in the water accumulation disc, and the increase of the water level in the water accumulation disc needs to be controlled in order to avoid serious water accumulation. At the moment, the running frequency of the compressor is reduced, the generation amount of refrigerants in the indoor heat exchanger of the air conditioner can be reduced, the temperature of the indoor heat exchanger is improved, the generation of condensed water of the indoor heat exchanger is reduced, and therefore the increase of accumulated water in the water accumulation plate can be reduced.
Generally, the higher the rotating speed of the indoor fan of the air conditioner is, the higher the wind speed flowing through the indoor heat exchanger is. Through the rotational speed that improves indoor fan, can improve the temperature of indoor heat exchanger to a certain extent equally, perhaps alleviate the speed that indoor heat exchanger temperature reduces, and can accelerate the blowing off of indoor heat exchanger department steam, the production of reducible indoor heat exchanger comdenstion water to the increase of ponding in the reducible ponding dish.
When the real-time water level height in the ponding dish reaches a first preset height, ponding can be controlled by reducing the running frequency of the compressor, ponding can also be controlled by increasing the rotating speed of the indoor fan, and ponding can also be controlled by reducing the running frequency of the compressor and increasing the rotating speed of the indoor fan. And starting from the moment when the real-time water level in the water accumulation disc reaches a first preset height, the running frequency of the compressor is gradually reduced at a first speed reduction speed, and the rotating speed of the indoor fan is increased to a first preset rotating speed.
The embodiment provides a pair of air conditioner control method, water level height through real-time supervision ponding dish, and the increase of water level is controlled through the operation of adjustment air conditioner in time when the real-time water level height of ponding dish is higher, can effectually prevent that ponding dish water level is too high to lead to ponding serious, thereby can prevent because ponding dish ponding serious and the air conditioner refrigeration performance that leads to descend and appear blowing bad phenomenon such as water, be favorable to guaranteeing the normal operating of air conditioner, promote user experience.
And the water level in the ponding dish is directly monitored, the operation of air conditioner is controlled according to the change of the water level in the ponding dish, the prevention and control of the water level in the ponding dish can be more directly and effectively realized, and the ponding of the ponding dish is effectively prevented from being serious.
On the basis of the above embodiment, further, an air conditioner control method further includes: after the air conditioner compressor reduces the operation frequency at a first speed reduction and/or improves the rotating speed of an indoor fan of an air conditioner to a first preset rotating speed, whether the real-time water level height of the water collecting disc is increased or not is judged. The real-time water level height of the water accumulation disc within the first preset time after the rotating speed of the indoor fan of the air conditioner is reduced by the first speed reduction and/or is increased to the first preset rotating speed of the air conditioner compressor can be obtained, and the real-time water level height of the water accumulation disc is compared with the first preset height to judge whether the real-time water level of the water accumulation disc is increased or not, namely whether control measures for the air conditioner are effective or not. The first preset time may be 3 seconds, 5 seconds, or the like, and may be determined through experiments.
If so, increasing the reduction speed of the operating frequency of the air conditioner compressor to a second reduction speed and/or increasing the rotating speed of the indoor fan of the air conditioner to a second preset rotating speed. Namely, the air conditioner is controlled to reduce the running frequency at a first speed reduction and/or improve the rotating speed of an indoor fan of the air conditioner to a first preset rotating speed, so that the increase of accumulated water in the water accumulation disc cannot be effectively controlled.
At this time, the reduction speed of the operating frequency of the air-conditioning compressor is increased, so that the operating frequency of the air-conditioning compressor is gradually reduced at the second reduction speed, namely the operating frequency of the air-conditioning compressor is reduced more quickly. And/or the indoor fan is enabled to increase the rotating speed to a second preset rotating speed again on the basis of the first preset rotating speed. The generation of condensed water is reduced to a greater extent, and the accumulated water in the water accumulation plate is controlled.
If not, the air conditioner compressor is kept to operate at the first speed reduction speed, the operation frequency is reduced, and/or the indoor fan of the air conditioner operates at the first preset rotating speed until the real-time water level height of the water collecting disc is reduced to the second preset height. The air conditioner is controlled to reduce the running frequency at a first speed reduction and/or improve the rotating speed of the indoor fan of the air conditioner to a first preset rotating speed, so that the increase of accumulated water in the water accumulation disc can be effectively controlled, and the water level in the water accumulation disc is in a descending trend.
And controlling the air conditioner compressor to continuously and gradually reduce the operation frequency at the first speed reduction speed, and/or controlling the indoor fan of the air conditioner to continuously operate at the first preset rotating speed. I.e. the current control measures are maintained to further lower the water level in the drip tray to a second lower preset level.
On the basis of the above embodiment, further, after increasing the reduction speed of the operation frequency of the air-conditioning compressor to a second reduction speed and/or increasing the rotation speed of the indoor fan of the air-conditioning to a second preset rotation speed, if the real-time water level height of the water collecting tray decreases, the operation frequency of the air-conditioning compressor is reduced at the second reduction speed and/or the indoor fan of the air-conditioning operates at the second preset rotation speed until the real-time water level height of the water collecting tray decreases to the second preset height.

I.e. the current control measures are maintained to further lower the water level in the drip tray to a second lower preset level.
In the above embodiments, the first preset height is higher than the second preset height; the first deceleration is less than the second deceleration; the first preset rotating speed is less than the second preset rotating speed.
On the basis of the above embodiment, further, an air conditioner control method further includes: and when the real-time water level height of the water accumulation disc is reduced to a second preset height, restoring the operating frequency of the air conditioner compressor and/or the rotating speed of the indoor fan of the air conditioner to the corresponding frequency and/or rotating speed of the air conditioner under normal operation.

The second preset height is a relatively safe water accumulation height. When the water level in the water accumulation disc is lowered to the second preset height, the serious danger of water accumulation in the water accumulation disc is basically eliminated, and at the moment, the running frequency of the compressor and/or the rotating speed of the fan can be gradually restored to the frequency and the rotating speed before the water level in the water accumulation disc reaches the first preset height, namely the normal running of the air conditioner is restored.

Namely, if the water level in the water accumulation tray is not reduced after the control measure is applied to the air conditioner, if the water level in the water accumulation tray reaches the stop water level, the air conditioner is controlled to stop running so as to prevent the water level in the water accumulation tray from continuously increasing. The stop water level height is higher, when the accumulated water in the accumulated water tray reaches the stop water level height, the accumulated water in the accumulated water tray is more, and if the air conditioner is not stopped, the phenomena that the normal use of the air conditioner is influenced by water blowing and the like are more likely to be generated. The stop water level height is set as the guarantee water level height, and once the water level in the water accumulation plate is monitored to reach the stop water level height, the air conditioner is controlled to stop running, so that the air conditioner can be guaranteed not to influence normal use due to serious water accumulation of the water accumulation plate.
After the air conditioner is controlled to stop running, the water level in the water accumulation plate is continuously monitored so as to monitor the condition of the air conditioner constantly, obtain the time for starting the air conditioner in time and reduce the shutdown time of the air conditioner as much as possible.
