And after the fan coil receives the self-cleaning instruction, the fan coil enters a self-cleaning mode, and the motor and the electric heating device are controlled to be in a closed state. And then controlling an air conditioner water valve (a stop valve at the water outlet of the heat exchanger) to be in an open state, controlling the water inlet temperature of the heat exchanger within a preset temperature range, detecting whether the heat exchanger generates condensed water or not in real time, and controlling the fan to rotate reversely at a first rotating speed after the heat exchanger generates the condensed water.

The first rotation speed is R 1 The rotating speed of the motor is larger than or equal to the lowest rotating speed, and the motor cannot be started due to the fact that the set rotating speed of the motor is too low is avoided.
After the heat exchanger is judged to generate condensed water, the air outlet of the fan coil is controlled to be reduced to the size of the electric heating device, so that the circulating air can only pass through the electric heating device to enter and exit.
After 5s of delay, the fan is driven to rotate at a first rotating speed R 1 And when the rotating speed of the fan is low (or called as the circulating air volume is low), the air speed of the fan flowing through the heat exchanger device is still ensured to be high, so that sundries accumulated on the electric heating device are easier to separate.

wherein A is an adjustment coefficient, and the value range of A is 1.1-1.5.
Step S42 may be performed a plurality of times and the second rotational speed R may be adjusted by changing the value of a each time 2 。
This embodiment provides an empty time mode, which controls the empty time after the first positive and negative rotation of the motor is completedThe water regulating valve is opened, and after delaying for 10s, the motor rotates at a second rotating speed R 2 (R 2 ＝1.1×R 1 ) The air conditioner water valve is controlled to be closed after the operation is carried out for 60s in a reverse rotation mode, the motor is delayed for 10s according to a second rotating speed R 2 (R 2 ＝1.1×R 1 ) And (5) rotating forward for 30s, stopping the motor after the motor is finished, and finishing the forward and reverse rotation of the motor for the second time.
In the same way, the positive and negative rotation alternate action of the motor is carried out for the third time, and the motor rotates at the second rotating speed R 2 (R 2 ＝1.2×R 1 ) And (6) acting. And after the alternating action of positive and negative rotation of the motor is finished for three times, controlling the water valve of the air conditioner, the water inlet temperature and the air outlet to reset, and after 10s of delay, controlling the motor to operate according to a preset state and exiting from the self-cleaning mode.
By the method, the problem that the electric heating effect is poor after the electric heating device is accumulated by sundries after the fan coil is used for a long time is solved, the complicated cleaning process and potential safety hazards during manual cleaning are avoided, and meanwhile, an additional cleaning device is not required to be added. The maintenance cost is reduced, and meanwhile, the safety is improved.
