As shown in fig. 2, this embodiment further provides a control method of the zero-cold water supply system, including the following steps:
step S1, starting a water outlet device 3;
when hot water is required, the user turns on the water outlet device 3.
S2, hot water in the first water tank 2 flows out of the water outlet device 3;
in this step, since the first water pipe 4 and the second water pipe 6 are emptied and have a high air pressure after the last use, when the water outlet device 3 is turned on again, the air pressure in the first water pipe 4 is reduced, the hot water in the first water tank 2 flows from the first water pipe 4 to the water outlet device 3 and flows out from the water outlet device 3, and the water outlet device is used by a user to realize a zero-cold-water function, and since the second water tank inlet 501 is disposed at an upper position of the second water tank 5, the cold water in the second water tank 5 does not flow out from the second water pipe 6.
S3, hot water in the hot water supply device 1 flows into the first water tank 2;
in this step, after the hot water in the first tank 2 flows out, the hot water in the hot water supply device 1 flows into the first tank 2 to be replenished with hot water.
S4, closing the water outlet device 3;
after using the hot water, the user turns off the water outlet device 3.
And S5, starting the pressurizing piece 8, and pressing residual water in a pipeline between the first water tank water outlet 202 and the water outlet device 3 and a pipeline between the second water tank water inlet 501 and the water outlet device 3 into the second water tank 5.
In this step, after the water outlet device 3 is closed, the pressurizing member 8 starts to operate, that is, the air pump is started to increase the air pressure in the first water pipe 4 and the second water pipe 6, so that the water remaining in the first water pipe 4 and the second water pipe 6 is pressed into the second water tank 5, and no cold water remains in the first water pipe 4 and the second water pipe 6. And, because the first water pipe 4 and the second water pipe 6 are in a sealed state at this time, the water in the first water tank 1 cannot flow out due to the internal air pressure, so that the state without cold water residue is maintained, and the water outlet device is started next time.
As shown in fig. 3, the detailed steps of the control method of the present embodiment include:
step one, starting a water outlet device 3;
when hot water is required, the user turns on the water outlet device 3.
Step two, hot water in the first water tank 2 flows out from the water outlet device 3;
in this step, since the first and second water pipes 4 and 6 are emptied and have a high air pressure after the last use, when the water outlet device 3 is turned on again, the air pressure in the first water pipe 4 is reduced, and the hot water in the first water tank 2 flows from the first water pipe 4 to the water outlet device 3 and flows out from the water outlet device 3 for use by a user, while the cold water in the second water tank 5 does not flow out from the second water pipe 6 because the second water tank inlet 501 is disposed at an upper position of the second water tank 5.
Step three, detecting a water flow signal in a pipeline between the water outlet 202 of the first water tank and the water outlet device 3, and opening a second on-off control part 13;
in this step, after the hot water in the first water tank 2 flows out from the water outlet device 3, the flow rate detector 9 detects that a water flow signal is generated in the first water pipe 4, that is, the water outlet device 3 is opened, and the control unit controls to open the second on-off control member 13, so that the hot water in the hot water supply device 1 can flow into the first water tank 2 to supplement the hot water.
Step four, hot water in the hot water supply device 1 flows into the first water tank 2;
in this step, the hot water in the hot water supply device 1 flows into the first water tank 2 to be replenished with hot water.
Step five, closing the water outlet device 3;
after using the hot water, the user turns off the water outlet device 3.
Step six, detecting a water flow stop signal in a pipeline between the first water tank water outlet 202 and the water outlet device 3, and closing the first on-off control element 10;
in this step, after the water outlet device 3 is closed, the flow detecting element 9 detects that there is no water flow signal in the first water pipe 4 and the water flow signal stops, that is, the water outlet device 3 is closed, and the control unit controls to close the first on-off control element 10 to prepare for pressurization of a subsequent pipeline.
And step seven, starting the pressurizing piece 8, and pressing residual water in a pipeline between the first water tank water outlet 202 and the water outlet device 3 and a pipeline between the second water tank water inlet 501 and the water outlet device 3 into the second water tank 5.
In this step, after the water outlet device 3 is closed, the pressurizing member 8 starts to operate, that is, the air pump is started to increase the air pressure in the first water pipe 4 and the second water pipe 6, so that the water remaining in the first water pipe 4 and the second water pipe 6 is pressed into the second water tank 5, and no cold water remains in the first water pipe 4 and the second water pipe 6. And, because the first water pipe 4 and the second water pipe 6 are in a sealed state at this time, the water in the first water tank 1 cannot flow out due to the internal air pressure, so that the state without cold water residue is maintained, and the water outlet device is started next time.
Further, after the pressurization of the pipeline is completed, the control unit can open the first on-off control element 10 to prepare for the next use of hot water, and due to the fact that the air pressure in the first water pipe 4 and the second water pipe 6 is high, the hot water in the first water tank 2 cannot flow into the first water pipe 4 after the first on-off control element 10 is opened, and therefore the time for starting the water outlet device and flowing out the hot water next time is saved.
As shown in fig. 4, the control method of the zero-cold-water supply system of the present embodiment further includes a temperature water level control step, including:
step (1), detecting the water temperature in the first water tank 2;
whether the water outlet device 3 is opened or not, the water temperature in the first water tank 2 is detected by the temperature detection part 12 at intervals so as to detect whether the water temperature meets the preset temperature requirement or not.
Step (2) judging whether the current water temperature T is 1 Not less than preset water temperature T 0 Preset water temperature T 0 The value of (A) can be preset;
step (1) if T 1 ＜T 0 If so, heating the water in the first water tank 2 and continuously detecting the water temperature in the first water tank 2; specifically, the control unit controls the heating member 7 to heat the water in the first water tank 2, and then continues to detect the temperature of the water in the first water tank 2.
Step (2) if T 1 ≥T 0 Detecting the water level in the first water tank 2;
step (3) judging whether the current water level H is present 1 Not less than preset water level H 0 Preset water level H 0 The value of (A) can be preset;
step I, if H 1 ＜H 0 Then the third breaking control 16 is opened, time delay t 0 After the time, closing the third cut-off control member 16 and continuing to detect the temperature of the water in the first water tank 2; specifically, the control unit opens the third cut-off control member 16 to make the cold water in the second water tank 5 feed into the first water tank 2, and the control unit controls the cold water to flow into the first water tank 2 at the extending time t 0 After time (t) 0 Can be preset, for example 30s, etc.), the third shut-off control 16 is closed by the control unit.
Step II, if H 1 ≥H 0 And the temperature of the water in the first water tank 2 is continuously detected.
Through above-mentioned step, can ensure that the water storage capacity and the temperature in the first water tank 2 all satisfy the user's requirement, further realize the user and use instant heating, promote user experience by a wide margin.
