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 like wash hand, wash the dish and wash the bowl the scene, the requirement to quality of water is not high, can use domestic water to reduce and use through the pure water, avoid extravagant electric quantity, consume the energy. The technical scheme of this application is through separately heating pure water and domestic water, therefore the user can select pure water or domestic water according to actual conditions to the needs of the different occasions of adaptation user.

The water purifying and heating dual-purpose machine with compact structure is also provided with a purified water port a and a living water port b. The first water inlet end 011 is connected with an external waterway and provides tap water for the water purifying and water heating dual-purpose machine with compact structure; the purified water port a is connected with the water outlet end of the heating component 6 and is used for discharging purified water; the domestic water gap b is connected with the water outlet end of the water mixing valve 8 and is used for discharging domestic water.

The production process of the domestic water comprises the following steps: tap water firstly enters the composite filter element 1 from the first water inlet end 011, and the composite filter element 1 filters the tap water into domestic water; domestic water flows out from the water outlet end of the composite filter element 1 and enters the hot tank 7 through the water inlet end of the hot tank 7; the hot tank 7 heats the domestic water and stores the heated domestic water.

When a user needs to use the domestic water, the domestic water port b can be opened, and the heated domestic water enters the water mixing valve 8 through the water outlet end of the hot tank 7; meanwhile, part of the tap water enters the water mixing valve 8 from the fourth water inlet end 82; the tap water and the domestic water are mixed in the water mixing valve 8, so that the temperature of the domestic water is adjusted; the mixed domestic water flows out of the water outlet end of the water mixing valve 8 and enters the domestic water gap b, and the compact-structure dual-purpose machine for purifying and heating water supplies the domestic water to users through the domestic water gap b.

The filtration process of the purified water is as follows: firstly, running water enters the composite filter element 1 from a first water inlet end 011, and the composite filter element 1 filters the running water into primary filtered water; then, the primary filtered water flows out from the first water outlet end 013 of the composite filter element 1, enters the booster pump 2 through the water inlet end of the booster pump 2, and is pumped out from the water outlet end of the booster pump 2 by the booster pump 2; the primary filtered water enters the RO membrane filter element 4 through the water outlet 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 composite filter element 1 again through the second water inlet end 012 of the composite filter element 1; the composite filter element 1 filters the secondary filtered water into purified water, and the purified water flows into the heating assembly 6 from a second water outlet end 014 of the composite filter element 1; when a user needs to use the purified water, the purified water port a can be opened, and the heating assembly 6 starts to heat the purified water; the heated purified water flows out from the water outlet end of the heating component 6; the water purifying and heating dual-purpose machine with compact structure provides the heated purified water for users through the purified water port a.

The waterway from the first water inlet end 011 to the first water outlet end 013 in the composite filter element 1 is not communicated with the waterway from the second water inlet end 012 to the second water outlet end 014, so that the secondary filter water and the primary filter water which are filtered by the RO membrane filter element 4 are prevented from being mixed.

When the switches of the domestic water and the purified water are turned on simultaneously, the composite filter element 1 cannot provide enough primary filtered water simultaneously so as to meet the requirements of the domestic water and the purified water, and therefore the domestic water needs to be filtered in advance; the domestic water filtered by the composite filter element 1 is stored by the hot tank 7, so that the problem of insufficient water supply is avoided. Moreover, the hot tank 7 can heat domestic water; the heated domestic water is mixed with tap water to adjust the temperature so as to meet the requirements of users in different occasions.

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 of the water channel; when the pure water port a is closed, the booster pump 2 can continue to work, when the water pressure of the water channel between the RO membrane filter element 4 and the composite filter element 1 is gradually increased, and when the pressure of the water channel 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 the water channel is prevented from being broken due to overlarge pressure;

when pure mouth of a river a was opened, the pure water flowed from pure mouth of a river a, and the pressure in water route diminishes, and when the water pressure in water route was less than the pressure threshold value between RO membrane filter core 4 and composite filter core 1, pressure switch 3 opened, starts booster pump 2. When the booster pump 2 works, the booster pump 2 makes primary filtered water enter the RO membrane filter element 4, and the secondary filtered water enters the composite filter element 1 for filtering so as to supplement purified water, so that the purified water can stably flow out from the purified water port a.

Referring to fig. 2, specifically, the composite filter element 1 includes a front filter element waterway and a rear filter element waterway, and the front filter element waterway and the rear filter element waterway are independently arranged; the both ends in leading filter core water route are connected with first end 011, the first end 013 that goes out of intaking respectively, the both ends in rearmounted filter core water route are connected with second end 012, the second end 014 that goes out of intaking respectively.

In a specific embodiment, the composite filter element 1 is a three-in-one composite filter element, and the composite filter element 1 is formed by combining a PP cotton filter element, a front carbon rod filter element and a rear carbon rod filter element; the cotton filter core of PP and leading carbon-point filter core setting are in leading filter core water route, and rearmounted carbon-point filter core setting is in rearmounted filter core water route. Leading filter core water route does not communicate with rearmounted filter core water route, avoids mixing through the filterable second grade drainage of RO membrane filter core 4 and primary drainage.

After entering the composite filter element 1, tap water is filtered by a PP cotton filter element and a front carbon rod filter element in a front filter element water path. After passing through the water path of the front filter element, the primary filtered water respectively enters the booster pump 2 and the domestic water branch 015.

A part of the primary filtered water enters the hot tank 7 through the water inlet end of the hot tank 7; and the other part of the primary filtered water enters the RO membrane filter element 4 through the pressurization of the booster pump 2, is filtered into secondary filtered water, then enters the post-filter element water path through the second water inlet end 012 of the composite filter element 1, and is subjected to tertiary filtration through the post-carbon rod filter element.

The cotton filter core of PP can carry out the first filtration to the running water, and leading carbon-point filter core has the adsorption effect, can adsorb the impurity in elementary filtration, reduces the impurity that gets into RO membrane filter core 4 to alleviate RO membrane filter core 4's filtration burden, also can prolong the live time of RO membrane simultaneously. The rear carbon rod filter core can adsorb peculiar smell, so that the taste of the purified water is sweet.

Specifically, the heating assembly 6 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 5 is arranged between the water outlet end of the RO membrane filter element 4 and the pressure switch 3. The check valve 5 ensures that the secondary filtered water can only flow to the post-positioned carbon rod filter element in a one-way manner, and the secondary filtered water is prevented from flowing back to the RO membrane filter element 4 again.

In a preferred embodiment, the compact dual-purpose machine for purifying water and heating water further comprises a water outlet c, the RO membrane filter element 4 is further provided with a sewage discharge port 41, and the sewage discharge port 41 is connected with the water outlet c.

The water purifying and water heating dual-purpose machine with compact structure can also generate cleaning wastewater, and the cleaning wastewater is generated when the RO membrane filter element 4 (reverse osmosis membrane filter element) 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.

Moreover, when the water purifying and heating dual-purpose machine with compact structure 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 water-purifying and water-heating dual-purpose machine with compact structure stops producing water for a period of standby 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 compact dual-purpose machine for water purification and hot water needs to discharge the water staying in the RO membrane filter element 4 at regular time, so that the water in the RO membrane filter element 4 flows out of the drain outlet 41, thereby avoiding the problems of the rise of the total dissolved solid value and the microorganism content in the RO membrane filter element 4.

Preferably, a water inlet valve 31 is arranged between one end of the live water branch 015 and the water inlet end of the booster pump 2, the water inlet valve 31 is electrically connected with a pressure switch 3, and the pressure switch 3 is used for controlling the opening or closing of the water inlet valve 31. 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 a is opened, pure water flows out from the pure water port a, so that the pressure of a water channel between the water outlet end of the RO membrane filter element 4 and the second water inlet end 012 is reduced; when the pressure is lower than the 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; when the pure water port a is closed, the booster pump 2 still pumps the primary filtered water into the RO membrane filter element 4, so that the pressure of a water path between the water outlet end of the RO membrane filter element 4 and the second water inlet end 012 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.

A water-vapor separator 92 is arranged in the exhaust water tap 9, and a partition plate 203 is arranged in the water-vapor separator 92; the heated purified water passes through the impact baffle 203, causing bubbles and water vapor to be expelled from the purified water.

Referring to fig. 5, specifically, the partition plates 203 include a first partition plate 203a, a second partition plate 203b, and a third partition plate 203 c; the first partition plate 203a, the second partition plate 203b and the third partition plate 203c are sequentially disposed inside the water vapor separator 92 in the flow direction of purified water;
