At the same time, the heating component 21 heats according to the cleaning power and makes the cleaning liquid reach the required liquid level. After the cleaning work is completed, the second solenoid valve 12 opens to discharge the waste water; if the cleaning liquid is insufficient, the third solenoid valve 14 and the fourth solenoid valve 15 open, and cooperate with the liquid level meter 9 and the pH sensor 10 to replenish the appropriate cleaning liquid.

The steam generator 2 of the hardness tester 4 is set as the reference steam generator 2.

The intelligent control unit 18 then collects and calculates the heating power and duration of other steam generators 2 to infer their water hardness, thereby determining whether to issue a cleaning signal. To account for the variability and uncontrolled nature of the water supply quality of steam generators 2, the intelligent control unit 18 continuously collects the heating power, duration, and hardness value data of the reference steam generator 2, and promptly updates the corresponding map to ensure the accuracy of the water hardness inferred for other steam generators 2.
