Abstract
A control method and device for the automatic water-replenishing for a boiler iron producing continuous steaming is disclosed. The method, which comprises a normally-closed pressure switch that can control power on/off of the boiler with respect to pressure and a normally-closed thermostat for maintaining a boiler thermostatic state, comprises the following steps: (1) determining whether the thermostat switch is off; if yes, step (3) is carried out, and if no, step (2) is carried out; (2) detecting whether the steam is being ejected; if yes, the electromagnetic valve will be opened to eject steam, while simultaneously pumping a relatively small amount of water into the boiler; (3) controlling the pump to pump a large amount of water into the boiler. According to a preferred embodiment of the present invention, in step (2), the quantity of water is slightly less than the quantity of water that is ejected as steam.
