When the water level switch is switched off, the abnormal condition of the air conditioner drainage system is indicated, and when the water level switch is switched off, the normal condition of the drainage system is indicated. When the water level switch is disconnected, the input pin of the air conditioner control processor can detect a high level, namely a high level signal is received, and the water pump control module controls the drainage pump to be started according to the high level signal. When the water level switch is closed, the input pin of the air conditioner control processor detects a low level, namely receives a low level signal, and the water pump control module controls the drainage pump to be closed according to the low level signal. In summary, when the input pin of the air conditioner control processor detects a high level, the drainage system is abnormal, the drainage pump is turned on at this time, and the water in the condensed water tray is drained in time, when the input pin of the air conditioner control processor detects a low level, the drainage system is normal, and the drainage pump is turned off at this time, so that energy consumption is saved.
It should be noted that, in order to avoid the pump not to be started or closed, when the air conditioner control processor receives the high level signal, the timing is started, and if the recorded duration of continuously receiving the high level signal is greater than the preset threshold, for example, the air conditioner control processor continuously receives the high level signal for 5s, the air conditioner control processor outputs the high level signal to the drain pump control module, so as to avoid the pump not to be started. Similarly, when the duration of the air conditioner control processor continuously receiving the low level signal is greater than the preset threshold value, the air conditioner control processor outputs the low level signal to the drain pump control module to avoid the stop of the drain pump.

when the base of the triode 1023 receives a high-level signal output by an output pin of the air conditioner control processor 101, the collector and the emitter are conducted;
when the collector and the emitter of the transistor 1023 are turned on, the high-level signal flows through the coils on the first and second contacts of the relay 1022, and the third and fourth contacts of the relay 1022 are closed, so that the drain pump 1021 is communicated with the live wire, and the drain pump 1021 is turned on.

Similarly, when the output pin of the air conditioner control processor outputs a low level, the collector and the emitter of the triode are disconnected, no current passes through the coil of the relay, the third contact and the fourth contact of the relay are disconnected, the wiring L of the draining pump is disconnected with the 220V live wire of the power supply, and the draining pump stops running.

the water level detection module 201 is further configured to alarm according to the alarm signal.
For example, when the second duration that the air conditioner control processor continuously receives the high level signal is greater than the preset second duration threshold, it is described that the water level switch in the water level detection module is continuously in the off state within the second duration, that is, the drainage system of the air conditioner is in the abnormal state within the second duration, at this time, the air conditioner is controlled to stop running, so as to avoid damaging the air conditioner, and the water level detection module gives an alarm, for example, the abnormal information of the drainage system is displayed through a display screen, or a warning sound is emitted, so as to prompt a user to timely handle a fault, so that after the drainage pump is damaged, the continuously increased condensate water overflows a condensate water tray, and other devices of the air conditioner or other properties near the air conditioner are damaged.
