The flow rate can be adjusted from 0.3L/min to 1.5L/min by adjusting the voltage, so that the flow requirements of the instant heating body from different temperature ranges of 35 ℃ to 100 ℃ are met. The cold water pump 6 is specifically a double-check water pump, and can realize forward stop even when the work is stopped. Meanwhile, the pressure reducing valve 5 can reduce the pressure of the inlet water to a certain value, so that the pressure stabilizing effect is realized, and the service life of the cold water pump 6 is prevented from being reduced due to insufficient pressure resistance.
When water with different temperatures is prepared, the power of the cold water pump 6, the hot water pump 7 and the instant heating body 4 is required to be adjusted according to actual conditions, and the power adjustment conditions of the cold water pump 6, the hot water pump 7 and the instant heating body 4 for preparing water with different temperatures are explained one by one.
The water intake temperature of the hot water port is set to be T, the temperature of the heat preservation water in the heat preservation pipeline 200 is set to be T Protection device , and the purified water temperature in the purified water pipeline 100 is set to be T 0, and at the moment, T 0≤T Protection device is set.
When T 0＜T＜T Protection device is reached, according to the water taking temperature T, the cold water pump 6 and the hot water pump 7 are started according to the set power ratio; or the hot water pump 7 is turned off, and the cold water pump 6 and the instant heating body 4 are turned on according to the set power according to the water taking temperature T.
At the water taking temperature, the water taking temperature is not high, so that the cold water pump 6 and the hot water pump 7 can be directly started according to the set power ratio to perform water mixing operation, and the instant heating body is not required to be started under the condition. The power ratio of the cold water pump to the hot water pump is determined specifically according to the water taking temperature T, specifically, when the water taking temperature T is closer to the water purifying temperature T 0, the power ratio of the cold water pump 6 to the hot water pump 7 is relatively large, that is, the cold water pump 6 is mainly operated at this time, and when the water taking temperature T is closer to the temperature T Protection device of the heat-insulating water, the power ratio of the cold water pump 6 to the hot water pump 7 is relatively small, that is, the hot water pump 7 is mainly operated at this time.
It should be noted that, the above-mentioned mode mixes the water mode and is the ideal state, can obtain the temperature slightly below water intaking temperature T through mixing the water operation in the actual operation, and the temperature compensation is carried out to the heat medium 4 promptly again, finally realizes accurate temperature play water. The water taking temperature can also realize accurate temperature water outlet by only using the cold water pump 6 and the instant heating body 4 to work, specifically, the hot water pump 7 is turned off, and the instant heating body 4 is directly used for instant heating water outlet.
Taking hot water at 60-74 ℃ as an example, after the water mixing operation is carried out by utilizing the purified water in the purified water pipeline 100 and the warm water in the heat preservation liner 3, the temperature is compensated to the required temperature through the water inlet NTC of the instant heating body 4 after detection, namely the temperature of the instant heating body 4. The outlet water temperature is detected and judged by the outlet NTC of the instant heating body 4. The excessive purified water in the purified water pipeline 100 flows back to the front end of the booster pump 1 through the pressure relief pipeline 300, so that the pressure in front of the membrane is reduced.
Meanwhile, taking hot water at the temperature of 35-59 ℃ as an example, the hot water pump 7 is turned off, the cold water pump 6 pumps the clean water in the clean water pipeline 100 into the instant heating body 4, the instant heating body 4 compensates the temperature of the hot water, and the redundant clean water in the clean water pipeline 100 flows back to the front end of the booster pump 1 through the pressure relief pipeline 300, so that the pressure in front of a membrane is reduced.
When T is more than or equal to T Protection device , according to the water taking temperature T, namely the full power of the heating body 4 is started, the cold water pump 6 is closed, and the hot water pump 7 is started according to the set power, so that the maximum flow rate of hot water is ensured to be discharged.
At the water intake temperature, the water intake temperature T exceeds the temperature T Protection device of the heat preservation water, so that the warm water flowing in the heat preservation pipeline 200 can be directly heated, at this time, the cold water pump 6 does not need to participate in the work, and meanwhile, the heat body 4 is opened in a full power mode, so that the maximum flow rate of hot (boiled) water is ensured, and the waiting time of hot water for a user is also greatly shortened.
Taking hot water at 81-100 ℃ as an example, the hot water pump 7 pumps the temperature in the heat preservation liner 3 into the instant heating body 4 to perform compensation heating, and the pressure relief pipeline 300 does not perform pressure relief because the cold water pump 6 does not work at the moment.

When the accumulated water outlet time t is greater than the set value under the water intake temperature and the water intake amount, that is, the warm water of the heat preservation liner 3 is nearly emptied, the set value of the time can be adjusted according to specific conditions, for example, the set value of the time can correspond to the low water level of the heat preservation liner 3. At this time, the working power of the hot water pump 7 needs to be properly adjusted, and meanwhile, the power of the cold water pump 6 is adjusted according to the water taking temperature T and the water purifying temperature T 0, specifically, when the difference between the water taking temperature T and the water purifying temperature T 0 is larger, the power of the cold water pump 6 is properly adjusted to reduce the flow rate, meanwhile, the power of the instant heating body 4 can be properly increased to enable the flow rate not to be too low, and when the difference between the water taking temperature T and the water purifying temperature T 0 is smaller, the power of the cold water pump 6 is properly adjusted to increase the flow rate, and the power of the instant heating body 4 can be synchronously increased to realize higher flow rate.
When the water level in the heat preservation liner 3 is low, hot water outlet water at 35-100 ℃ mainly can be directly and instantly heated by the instant heating body 4, and redundant clean water in the clean water pipeline 100 flows back to the front end of the booster pump 1 through the pressure relief pipeline 300, so that the pressure in front of a membrane is reduced.

In the water intake process, when the water purifying outlet flow of the filter assembly is larger than the outlet flow of the outlet end of the pressure reducing valve 5, the reflux valve 8 and the water inlet valve 9 are opened simultaneously. When the water purification water outlet flow is greater than the water outlet flow of the water outlet end of the pressure reducing valve 5, namely, the pipeline is subjected to pressure holding phenomenon, the reflux valve 8 is synchronously opened at the moment, synchronous pressure relief can be completed, the pressure in front of the filter element 2 film is effectively reduced, the loads of the filter element 2 and the booster pump 1 are greatly reduced, the filter element 2 and the booster pump 1 are protected, and the service life of the filter element is prolonged.
