(2) And electrifying the timer, and simultaneously setting the working time interval and the working time length of the self-cleaning device. (3) When the timer reaches the self-cleaning time and the pressure sensor detects that the water pressure of the pressure-bearing water storage tank meets the requirement, the water inlet electromagnetic valve and the water outlet electromagnetic valve are opened, and water is sprayed through the evaporator spray nozzle and the chassis spray nozzle to flush the evaporator and the chassis. (4) When the set working time is up, the water inlet electromagnetic valve and the water outlet electromagnetic valve are closed, the pressure switch is closed, and the spraying is stopped.
The invention has the beneficial effects that:
according to the evaporator and chassis self-cleaning device of the air energy water heater, the timer sets the time interval and the working time, the pressure sensor detects the water pressure and controls the opening and closing of the electromagnetic valve, the actions of the water inlet electromagnetic valve and the water outlet electromagnetic valve are effectively controlled, the automatic spraying and flushing of the evaporator and the chassis are realized, and the problem that the dust and dirt accumulation of the evaporator and the chassis of the air energy water heater troubles users is effectively solved.
