Specifically, first, the amount of water discharged from the water stored in the air dissolving tank to the outside is acquired. Then judging whether the water discharge is larger than the volume of the dissolved air tank or not; if yes, the electromagnetic valve is opened again; if not, the gas water heater returns to the micro-bubble inflation mode. Here, the controller measures the water flow according to the water flow sensor in real time and carries out row calculation to obtain the displacement, if the displacement is greater than the volume of the dissolved air tank, the dissolved air tank is determined to be drained of clear water and filled with air, and the controller opens the electromagnetic valve to conduct the water path between the water pipe and the water outlet pipe again, so that external water supply flows into the dissolved air tank again.
And step S105, judging whether the current water flow value is larger than the preset starting-up flow value again, and determining to open the gas valve according to the judgment result so as to enable the gas water heater to enter a micro-bubble operation mode.
Specifically, judging whether the current water flow value is larger than the preset starting-up flow value again;
if yes, opening a gas valve;
and if not, returning the gas water heater to the micro-bubble standby mode.
In this embodiment, after external water supply flows into the dissolved air tank again, the controller measures the water flow in real time according to the water flow sensor again to obtain the current water flow value, if the current water flow value is smaller than the preset startup flow value, it is determined that the user has turned off the water, and the controller turns off the water pump and switches back to the microbubble standby mode again; if the current water flow value is larger than the preset starting-up flow value, the fact that the user still uses water is judged, the controller opens the control valve to enable the gas water heater to be started up, ignited and heated to supply water to the outside, and therefore the gas water heater is switched from the micro-bubble inflation mode to the micro-bubble operation mode.
In this embodiment, in the microbubble operation mode, the external water flows into the dissolved air tank, is mixed with the air inside the dissolved air tank under the action of the spoiler to form tap water with bubbles, and is then mixed by the high-speed disturbance of the water pump impeller, so that the air is completely dissolved in the water, and then the microbubble water with the gas-liquid mixing ratio of about 3% -8% is formed. In addition, if the volume of the dissolved air tank is 1.5L and the water outlet flow is set to be 6L/min, the gas water heater can output micro-bubble water for 10 min.
And step S106, judging whether the current water flow value is larger than the preset starting-up flow value again, and determining to close the water pump and the gas valve simultaneously according to the judgment result so as to enable the gas water heater to exit the micro-bubble operation mode.
Specifically, judging whether the current water flow value is larger than the preset starting-up flow value again;
if so, the gas water heater continues to return to the micro-bubble operation mode;
if not, the water pump and the gas valve are closed at the same time.
In this embodiment, in the microbubble operation mode, the controller measures the water flow in real time according to the water flow sensor again to obtain the current water flow value, and if the current water flow value is greater than the preset startup flow value, the controller controls the gas water heater to continue to return to the microbubble operation mode, so as to continue to perform output work for microbubble water; and if the current water flow value is smaller than the preset starting-up flow value, closing the water pump and the gas valve simultaneously so as to close the gas water heater.
