Because the pure water needs to carry out the pressure boost through booster pump 2 and filter, and booster pump 2 needs electric power to provide power, consumes energy, when the user carries out the scene such as washing hand, washing vegetable and washing the dishes, the requirement to quality of water is not high, can use domestic water to reduce and use the pure water, avoid extravagant electric quantity, consume the energy. The technical scheme of this application is through separately storing and separately heating pure water and domestic water, therefore the user can select through pure water or through domestic water according to actual conditions to the needs of the different occasions of adaptation user.
The water inlet a is connected with a tap water source and provides tap water for the dry-burning-proof dual-purpose machine for purifying and heating water; the purified water port b is used for discharging purified water, the domestic water port c is used for discharging domestic water, and the water outlet d is used for discharging cleaning wastewater.
The filtering process of the living water comprises the following steps:
when a user needs to use domestic water, the switch of the domestic water port c can be opened, and tap water enters the dry-burning-proof water purifying and heating dual-purpose machine from the water inlet a; then enters the composite filter element 1 through the water inlet end of the composite filter element 1, and the composite filter element 1 filters tap water into domestic water; domestic water flows out from the water outlet end of the composite filter element 1 and flows into a domestic water port c through a domestic water branch 011, and the dry-burning-proof water purifying and heating dual-purpose machine provides domestic water for users through the domestic water port c.
The filtration process of the purified water is as follows:
firstly, running water enters the dry-burning-proof clean water heating dual-purpose machine from a water inlet a; tap water enters the composite filter element 1 through the water inlet end of the composite filter element 1, and the composite filter element 1 filters the tap water into primary filtered water;
then, the primary filtered water flows out from the water outlet end of the composite filter element 1 and enters the booster pump 2 through the water inlet end of the booster pump, and the booster pump 2 pumps the primary filtered water out from the water outlet end of the booster pump; the primary filtered water enters the RO membrane filter element 4 through the water inlet end of the RO membrane filter element 4 due to the pressure generated by the booster pump 2; the RO membrane filter element 4 filters the primary filtered water into secondary filtered water by a reverse osmosis principle;
finally, the secondary filtered water flows out from the water outlet end of the RO membrane filter element 4 and enters the post-carbon rod filter element 5 through the water inlet end of the post-carbon rod filter element 5; the post-carbon rod filter element 5 filters the secondary filtered water into purified water, and the purified water flows into the pressure tank 6 from the water outlet end of the post-carbon rod filter element 5 to be stored; when a user needs to use the purified water, the switch of the purified water can be turned on, so that the internal pressure of the pressure tank 6 is changed, and the purified water is supplied into the heating assembly 7 through the water inlet end of the heating assembly 7; the heating component 7 heats the purified water, and the heated purified water enters the purified water port b through the water outlet end of the heating component 7; the dry-burning-preventing water purifying and heating dual-purpose machine provides the purified water after heating for users through the purified water port b.
The rear carbon rod in the rear carbon rod filter element 5 can adsorb impurities and peculiar smell in the secondary filtered water, so that the taste of the water is sweet.
The pressure switch 3 has a pressure threshold value, and can automatically control the booster pump 2 to be opened or closed according to the water pressure; open when pure mouth of a river b, behind the 6 pure water of discharge of overhead tank, the pure water flows from pure mouth of a river b, and the waterway pressure between RO membrane filter core 4 and the rearmounted carbon-point filter core 5 diminishes, and when the waterway between RO membrane filter core 4 and the rearmounted carbon-point filter core 5 was less than the pressure threshold value, pressure switch 3 opened, starts booster pump 2. When the booster pump 2 works, the booster pump 2 enables primary filtered water to sequentially pass through the RO membrane filter element 4 and the rear carbon rod filter element 5 for filtering so as to supplement purified water, and the purified water can stably flow out of the purified water port b;
when pure mouth of a river b closes, because booster pump 2 can continue work, after overhead tank 6 holds full pure water, the water route pressure between RO membrane filter core 4 and the rearmounted carbon-point filter core 5 grow gradually, when pressure is greater than pressure switch 3's pressure threshold value, pressure switch 3 closes, make booster pump 2 stop work, avoid the water route between RO membrane filter core 4 and the rearmounted carbon-point filter core 5, the water route between rearmounted carbon-point filter core 5 and overhead tank 6, the water route between overhead tank 6 or overhead tank 6 and the pure mouth of a river b breaks because of the pressure is too big.
In the conventional water purifier, pure water is prepared and used, and therefore, when the water pressure is insufficient or water is cut off, the pure water supplied to the heating unit 7 is less or even cannot be supplied to the heating unit 7, and therefore, the heating unit 7 is easily dried, and the heating unit 7 is damaged. The pressure tank 6 is arranged, the water storage effect can be achieved, purified water can be temporarily stored in the pressure tank, when a user needs to use water, the pressure tank 6 can provide a certain amount of purified water, and the composite filter element 1, the RO membrane filter element 4 and the rear carbon rod filter element 5 can also generate purified water to supply to the heating assembly 7 or store the purified water in the pressure tank 6; when the water pressure is insufficient or the water is cut off, the pressure tank 6 can supply pure water to the heating assembly 7, so that the problem that the heating assembly 7 is dry-burned due to insufficient water pressure or water cut-off is avoided. Pressure tank 6 can temporarily save the pure water that the dual-purpose machine of clean water heating produced of preventing dry combustion method, when using the pure water, pressure tank 6 provides heating element 7 with the pure water of well storage, and convenient and fast can solve the supply problem of pure water.
In particular, the heating assembly 7 comprises a rare earth thick film assembly. The rare earth thick film subassembly is the existing technology as the firing equipment of heating pure water, and the rare earth thick film subassembly utilizes flexible nanometer tombarthite far infrared electric heat film heating technology, and the rationale is the joule effect that utilizes the electric current to flow through the conductor, turns into heat energy with the electric energy high efficiency. The user can set up the temperature that the tombarthite thick film subassembly heated according to actual conditions to the temperature of control pure water. The diversion water pipe in the rare earth thick film component is sealed and is not in direct contact with the electric heating conductor, so that water and electricity are separated, and the heating water circuit is not easy to deposit scale, so that the system is safer and more reliable; and the water flow can be instantly boiled and boiled after passing through the rare earth thick film component, so that the instant boiling and boiling can be realized, and the electricity is saved and the environment is protected.
Specifically, a check valve 8 is arranged between the water outlet end of the RO membrane filter element 4 and the pressure switch 3. The check valve 8 enables the secondary filtered water to flow to the post-positioned carbon rod filter element 5 in a one-way mode only, and the secondary filtered water is prevented from flowing back to the RO membrane filter element 4 again.

The dry-burning-proof dual-purpose machine for purifying and heating water can also generate clean waste water. The cleaning wastewater is generated when the RO membrane cartridge 4 (reverse osmosis membrane cartridge) is cleaned; after the RO membrane cartridge 4 completes the filtration, the surface of the RO membrane in the RO membrane cartridge 4 contains a large amount of salts, even organic matter, colloids, microorganisms, bacteria, viruses, and the like. These contaminants are easily deposited on the surface of the RO membrane, and contaminate the RO membrane elements, thereby reducing the performance of the RO membrane cartridge 4, such as reducing the flow rate of produced water, reducing the salt rejection rate, and increasing the pressure difference between the feed water and the concentrate. Therefore, it is desirable to utilize off-stream flushing of the RO membrane element surface to prevent the deposition of these contaminants.
In addition, when the dry-burning-proof dual-purpose machine for purifying and heating water is in a standby state for a long time, the booster pump 2 stops working, and a large amount of secondary filtered water and purified water subjected to reverse osmosis of the RO membrane are stored in the RO membrane filter element 4; diffusion of transmembrane concentrations can cause a problem commonly referred to as "head cup". The problem is embodied as: after the dry-burning-resistant water purifying and heating dual-purpose machine stops producing water for a period of time, the total dissolved solid value is higher than that of the machine during normal and stable operation. When the concentration of solute in the 'head cup water' is higher than a certain value, the problem of poor user experience can be brought, for example, the taste becomes poor, scaling is easy to occur after water boiling, and even potential risks can be brought to drinking water safety under extreme conditions.
Therefore, the dry-heating-preventing dual-purpose machine for purifying and heating water needs to be cleaned and drained at regular time, wherein the water stays in the RO membrane filter element 4; the flushing valve 9 is opened at regular time, so that the water in the RO membrane filter element 4 flows out of the sewage outlet 41, and the dry-heating-preventing water purifying and heating dual-purpose machine is used, thereby avoiding the problems of the rising of the total dissolved solid value and the rising of the content of microorganisms in the RO membrane filter element 4.

The water inlet valve 31 is matched with the booster pump 2 for use, so that the problems of water leakage and even water channel breakage caused by overlarge pressure of a water channel are avoided.
When the pure water port b is opened, the pressure tank 6 discharges the stored pure water, and the pure water filtered by the rear carbon rod filter element 5 enters the pressure tank 6, so that the pressure of a water path between the water outlet end of the RO membrane filter element 4 and the water inlet end of the rear carbon rod filter element 5 is reduced; when the pressure of a water path between the water outlet end of the RO membrane filter element 4 and the water inlet end of the rear carbon rod filter element 5 is lower than a pressure threshold value, the pressure switch 3 is opened, the booster pump 2 is started, and meanwhile, the pressure switch 3 also opens the water inlet valve 31, so that primary filtered water enters the booster pump 2 and is sequentially filtered by the RO membrane filter element 4 and the rear carbon rod filter element 5; when the pure water port b is closed, the booster pump continues to work, so that the primary filtered water continues to enter the RO membrane filter element 4, and the water path pressure between the water outlet end of the RO membrane filter element 4 and the water inlet end of the rear carbon rod filter element 5 is increased; when the pressure is greater than the pressure threshold value of the pressure switch 3, the pressure switch 3 is closed, so that the booster pump 2 stops working, and meanwhile, the water inlet valve 31 is closed, so that the primary filtered water is prevented from entering the booster pump 2.
