Referring to fig. 2, the method for controlling the drainage failure of the air conditioner 1000 includes steps S101 to S104.
And step S101, controlling the water pump 200 to be started.
Specifically, the controller 300 sends a start-up signal to control the water pump 200 to start.
In some embodiments, the user directly sends the power-on signal through the controller 300, such as by interacting with an air conditioner remote controller, a control button disposed on the housing 100, and the like, so that the controller 300 sends the power-on signal to control the water pump 200 to be turned on. This kind of mode of opening can make things convenient for the user to overhaul when air conditioner 1000 is improper drainage, makes air conditioner 1000's drainage mode more nimble simultaneously.

It is understood that after the start of the water pump 200 is confirmed, the driving torque of the water pump 200 is controlled to be decreased to that of the normal operation state.
The controller 300 sends a starting signal to control the water pump 200 to be started, so that the working index parameters of the water pump 200 can be acquired, whether the water pump 200 fails or not is determined according to the working index parameters, and after the water pump 200 fails, the water pump 200 is controlled to perform subsequent work according to the fault type of the working index parameters.
And S102, acquiring the working index parameters of the water pump 200.
Specifically, the operation index parameters of the water pump 200 may be collected by a sensor, and the operation index parameters of the water pump 200 may be transmitted to the controller 300 for processing.

The main controller is used for sending a startup/shutdown control signal and receiving the working index parameters of the water pump 200 transmitted by the sensor. The water pump controller is used for receiving the power-on/power-off control signal and directly controlling the water pump 200 to be powered on/off, and meanwhile, the water pump controller can acquire working index parameters of the rotating speed, current, voltage and the like of the water pump 200 without the help of a sensor and control the rotating torque of the water pump 200 through the working index parameters.
For example, the acquisition instruction may be generated in real time or at regular time and sent to the sensor. The timed duration can be set according to actual conditions, and specific numerical values are not limited herein.
And S103, determining whether the water pump 200 is in fault or not according to the working index parameters.
