a control method of a novel circulating preheating supercharging control system comprises the following steps:
s11, opening a switch key on a display operation panel, selecting a preheating function through the display operation panel, and adjusting a preset outlet water temperature through a temperature rising key and a temperature lowering key on the display operation panel;
s12, the main controller judges whether the water heater reaches a preheating starting condition or not by reading detection numerical values of the first temperature sensor, the first water flow sensor and the second water flow sensor, wherein the preheating starting condition is that a user does not use hot water when the water tap is started at a water using point, the temperature of water in the hot water pipe is lower than a target preheating temperature, the temperature of water in the hot water pipe can be known through the detection numerical value of the first temperature sensor, and whether the user uses hot water when the water tap is started at the water using point can be judged through the detection numerical values of the first water flow sensor and the second water flow sensor; when the preheating start condition is reached, the process proceeds to step S13; when the preheating starting condition is not met, the water electromagnetic valve keeps an initial closing state, and the whole control system does not execute any operation;
and S13, the main controller executes a preheating program, the water electromagnetic valve is started, the water pump starts to work, water in a circulating pipeline formed by the water heater, the hot water pipe, the first external control module and the cold water pipe flows in the circulating pipeline, the water heater is ignited for preheating, when the water flow temperature T detected by the first temperature sensor in the first external control module reaches the preheating temperature corresponding to the preset water outlet temperature set in the step S11, the water pump stops working, the water heater stops preheating, and the water electromagnetic valve is reset and closed. The preset outlet water temperature and the corresponding preheating temperature may be the same, or the corresponding preheating temperature may be lower than the preset outlet water temperature, for example, the commonly used preheating temperature may be 45 ℃.
Further, the step S13 specifically includes the following steps:
s131, the main controller executes a preheating program, a water electromagnetic valve is opened, a water pump starts to work, water in a circulating pipeline formed by the water heater, the hot water pipe, the first external control module and the cold water pipe flows in the circulating pipeline, at the moment, the water temperature in the circulating pipeline is t1, and the water flow is q 1;
s132, igniting and preheating the water heater, and increasing the water flow in the circulating pipeline to q2 when the water flow temperature T' detected by a second temperature sensor on a water outlet pipe of the water heater reaches T2, wherein T2 is greater than T1, T2 can be selected to be 5-10 ℃ higher than T1, for example, T1 is 20 ℃, and T2 can be selected to be 25 ℃;
s133, the water heater is continuously preheated, and when the water flow temperature T detected by the first temperature sensor in the first external control module reaches the preheating temperature T3 which is 1-2 ℃ lower than the preset outlet water temperature set in the step S11, the water flow in the circulating pipeline is reduced to q3, wherein T3 is greater than T2, and q3 can be the same as or different from q 1;

Like this, when main control unit carried out preheating program, the discharge in the circulating line was earlier little, the back is big, then diminishes again, can make the preheating temperature that rivers in the hot-water line reached more accurate, and the preheating efficiency of water heater is higher. The change of the water flow in the circulating pipeline can be realized by changing the rotating speed and the power of the water pump, and can also be realized by arranging a proportional valve on the circulating pipeline, and the water flow in the circulating pipeline can be monitored by a third water flow sensor. In addition, because the water flow in the circulating pipeline circularly flows in the preheating process, the water flow still has certain momentum at the moment of stopping preheating; therefore, when the water flow temperature T detected by the first temperature sensor reaches the preheating temperature corresponding to the preset outlet water temperature set in the step S11, the circulation flow is reduced first, and when the water flow temperature T detected by the first temperature sensor reaches the preheating temperature corresponding to the preset outlet water temperature set in the step S11, the water pump stops working, the water heater stops preheating, and the water electromagnetic valve is reset and closed, so that the problem that when the water pump is stopped and the water electromagnetic valve is closed just when the corresponding preheating temperature is detected in case of a large circulation flow, part of the water flow reaching the preheating temperature in the hot water pipe enters the cold water pipe due to the impact of the water flow can be avoided.

The preset values of Q1 and Q2 can be determined by experiments during the circulation flow preheating process, for example, the preset values of Q1 and Q2 are 2L/min, and when Q1 is more than or equal to 2L/min or Q2 is more than or equal to 2L/min, the user is judged to be using hot water during the circulation preheating process.
A control method of a novel circulating preheating supercharging control system comprises the following steps:
s21, opening a switch key on a display operation panel, selecting a pressurization function through the display operation panel, and adjusting a preset outlet water temperature through a temperature rise key and a temperature fall key on the display operation panel;
s22, the main controller enables the water electromagnetic valve to be not electrified, the initial closed state is maintained, a user opens the branch pipe at the hot water end of the water faucet at a water using point, when the water flow Q3 detected by the third water flow sensor is larger than or equal to a certain preset value, the preset value is usually selected to be 3L/min, the water heater is ignited and combusted, and at the moment, the water flow Q3 is recorded; and then the water pump starts to work, the water flow detected by the third water flow sensor is increased to be Q3', and the Q3' is more than or equal to Q3, so that when a user opens the water point faucet and uses hot water for bathing, the water flow is increased after the water pump is started for pressurization, the bathing comfort of the user is improved, and the larger the selected parameters such as the water pump flow, the lift and the like are, the larger the hot water outlet flow of the water faucet is after the water pump is started for pressurization.
And S23, after the user finishes bathing and closes the water faucet, Q1 is 0<2L/min, Q2 is 0<2L/min, the water pump stops, and because the water electromagnetic valve is in an initial closed state, water in a circulating pipeline formed by the water heater, the hot water pipe, the first external control module and the cold water pipe cannot flow even if the water pump works, namely the water flow Q3 detected by the third water flow sensor is 0, the water pump stops working, the water heater stops heating, and the water heater enters a standby state.

s31, opening a switch key on a display operation panel, simultaneously selecting preheating and pressurizing functions through the display operation panel, and adjusting the preset outlet water temperature through a temperature rising key and a temperature lowering key on the display operation panel;
s32, the main controller respectively judges whether a user uses bathroom hot water and whether the water heater reaches a preheating starting condition, and if the user does not use bathroom hot water and the water heater does not reach a circulating preheating starting condition, the water heater is in a standby state; if the user does not use the bathroom hot water but the water heater reaches the circulating preheating starting condition, the step S33 is executed; if the user uses the bathroom hot water without judging whether the water heater reaches the preheating starting condition, the step S34 is executed;

The operation principle of this step is the same as that when only the supercharging function is selected as described above.
