In step S2, the water level detection unit 21 is set to initially alarm the water level, so that the mobile air conditioner can reach the water level alarm in advance, and sufficient time is reserved for other steps, and during this time, the condensed water will not overflow the chassis.
In the step S4, if the detection result shows that the mobile air conditioner has a water pumping device, the water pumping device is started to remove condensed water in the chassis, so as to prevent later overflow; because the water pumping equipment has the preset water pumping time, namely B minutes, the water pumping equipment is automatically closed when the preset water pumping time is met after the water pumping equipment is opened for B minutes.

In step S5, if the detection result shows that the mobile air conditioner has no pumping equipment, the water level detection unit 21 continuously detects the water level in the chassis, and at this time, a water full alarm signal is not sent; since the optimum alarm water level is lowered in step S1, sufficient time is reserved so that the condensed water does not overflow the chassis. And, the advantage of the mobile air conditioner without the pumping equipment to continuously detect for C minutes is that the procedure is simple, if the mobile air conditioner has the pumping equipment, the procedure can be directly used without adjustment.
Preferably, the continuous detection time C minutes is 3 minutes.

In step S62, when the chassis water level detected again reaches the initial alarm water level, the alarm unit 23 sends an alarm signal, and the control unit 22 controls the mobile air conditioner to stop operating.
The continuous detection of D minutes is beneficial to the condition that the state of the pumping equipment after the pumping is finished is the same as the state of no pumping equipment, namely the pumping equipment and the no pumping equipment are both in the state of no water discharge.
Preferably, the continuous detection time D minutes is 1 minute.
EXAMPLE III

The mobile air conditioner continuously detects that the time C minutes is longer than the preset pumping time B minutes, and only if the preset pumping time B minutes is shorter than the water pump-free continuous detection time C minutes, the mobile air conditioner with the pumping equipment and without the pumping equipment can share one water drainage control program; and when the water level in the chassis is continuously detected for C minutes, the whole machine of the water-free pump and the water pump can enter the next round to detect the water level of the chassis again.
The time of continuously detecting the water level in the chassis for C minutes is less than A minutes in the step S2, because no alarm signal is sent out after the water level in the chassis is continuously detected for C minutes by the whole machine without the water pumping device, only when the continuously detected time for C minutes is less than A minutes in the step S2, the water in the chassis does not overflow after the continuously detected time for C minutes, and the normal operation of the whole machine is not influenced.
EXAMPLE five

EXAMPLE seven
The present embodiment of the mobile air conditioner drainage detection system as described above is different from the above embodiment in that the control unit 22 includes a water pump detection subunit 221 and a memory subunit 222.
When the water level detection unit 21 detects that the chassis water level reaches the initial alarm water level, a water level signal is transmitted to the control unit 22, and the water pump detection subunit 221 in the control unit 22 immediately detects whether the mobile air conditioner has a pumping device after receiving the signal that the water level reaches the initial alarm water level.
If the mobile air conditioner has a water pumping device as a result of the detection of the water pump detection subunit 221, the control unit 22 controls the water pumping device to be started and continuously pump water for B minutes; the memory unit 222 records that the mobile air conditioner has a water pumping device, and when the mobile air conditioner enters the water pumping mode again, the water discharge control method only performs the steps S4 and S6.
