whether the pressurizing function of the operation panel 17 is started or not is judged, and if so, the pressurizing function is started.
Preferably, the method comprises the following specific steps:
Triggering a water circulation mode, when the water circulation mode is triggered, starting an electric on-off valve 4 of a stepping motor, starting a circulating water pump 3 again, monitoring water flow in real time by a water flow sensor 5, feeding back the water flow to a main control circuit board 16, judging whether the water flow reaches a target value by the main control circuit board 16 according to a water flow feedback signal, if so, enabling a circulating waterway to work normally, and if not, reporting errors;
When the main control circuit board 16 sends a water flow feedback signal to the water heater 18, the water heater 18 judges that the water flow reaches a starting value according to the water flow feedback signal, and when the water heater 18 at least meets one of the starting values according to the water flow detected by the water flow sensor of the water heater 18, the water heater 18 is started to heat circulating water;
The circulating water temperature sensor 6 detects the actual water temperature and feeds back the actual water temperature to the main control circuit board 16, and the main control circuit board 16 judges whether the actual water temperature reaches the preset water temperature, if so, the circulating water pump 3 is closed, and then the stepping motor electric on-off valve 4 is closed.
Preferably, the method comprises the following specific steps:
Inputting a preset water flow value into an operation panel 17, and converting the preset water flow value into a target instruction by the operation panel 17 and outputting the target instruction to a main control circuit board 16;
the water outlet end water flow sensor 11 detects an actual water flow value and feeds back the actual water flow value as a flow signal to the main control circuit board 16;
The main control circuit board 16 compares the preset water flow value and the actual water flow value, judges whether the actual water flow value is consistent with the preset water flow value, if not, outputs a control instruction to the water flow regulating valve 12, and if so, outputs the hot water of the current actual water flow value for use;
The water flow rate regulating valve 12 regulates the opening of the water flow rate regulating valve 12 according to the control command, so that the actual water flow rate value is consistent with the preset water flow rate value.
Furthermore, the water flow sensor 11 at the water outlet end can also be used as a control signal that when the water flow sensor 11 at the water outlet end senses that the water flow reaches a preset value if a user uses hot water under the condition that the circulating water function is started, the water flow sensor 11 at the water outlet end feeds back a signal to the main control circuit board 16, the main control circuit board 16 outputs a signal to the circulating water pump 3 and the stepping motor electric on-off valve 4, the circulating water pump 3 stops working firstly, and then the stepping motor electric on-off valve 4 is closed to stop the circulating water function. Under the condition that the existing cold zero water heater is started by circulating hot water, if a user uses hot water, whether the user uses hot water or not cannot be accurately judged, the circulating water function and the user use hot water can be performed simultaneously, and the temperature of the output hot water is unstable and uncomfortable.
