Abstract
The invention relates to a reverse osmosis water purifier, which comprises a pretreatment filter element, a booster pump and reverse osmosis filter elements, wherein a tap water inlet is sequentially connected with the first pretreatment filter element, the booster pump, the second pretreatment filter element and the reverse osmosis filter element; and a liquid flow meter is arranged between the booster pump and the pretreatment filter element, and the booster pump starts or stops working according to a flow signal detected by the liquid flow meter. The water purifier adopts a mode of connecting reverse osmosis membrane filter elements in parallel, and controls the booster pump by the liquid flowmeter, thereby achieving the purposes of increasing water pressure and ensuring water outlet flow. The reverse osmosis water purifier without the water storage tank is sanitary and safe in water outlet and simple and convenient to operate.
Description
Technical field
The present invention relates to a kind of reverse osmosis water purifier for family or public arena, belong to water-treatment technology field, particularly the improvement opportunity of reverse osmosis water treatment system.
Background technology
Under the use environment of water purifier, impact by the construction features of reverse-osmosis membrane element itself, the aquifer yield of common reverse osmosis water purifier can only achieve 100��500ml/min, owing to its aquifer yield is less, therefore in use, needing to get up standby by water tank by the pure water collection made, namely drink owing to cannot accomplish namely to filter, therefore the pure water in water tank also has the risk being contaminated by bacterial; It addition, water tank is due to the construction features of himself, the ratio of condensed water can be made relatively to increase, cause the waste of water resource to a certain extent. Although some design can using water wisely to a certain extent (such as 200610147719.3), but if water tank exists, the loss of water resource is just unavoidable.
Summary of the invention
Solving the technical problem that of the present invention is in that to consider the problems referred to above and provide a kind of reverse osmosis water purifier without water tank, it is achieved namely fresh water is made and namely drunk, saving water resource.
Realization the technical scheme is that a kind of reverse osmosis water purifier, including preprocessing filter element, booster pump, reverse osmosis filter element, tap water water inlet is sequentially connected with the first preprocessing filter element, booster pump, second preprocessing filter element, reverse osmosis filter element, the condensed water branch road of reverse osmosis filter element and mistake drainage branch road are respectively connecting to condensed water outlet and pure water outlet, it is characterized in that: described reverse osmosis filter element includes parallel with one another two reverse osmosis filter element, it is connected to condensed water outlet after the condensed water branch circuit parallel connection of two reverse osmosis filter elements, it is connected to pure water outlet after the drainage branch circuit parallel connection excessively of two reverse osmosis filter elements, being provided with fluid flowmeter between described booster pump and preprocessing filter element, the flow signal that described booster pump detects according to fluid flowmeter starts or stops work.
Preferably, described fluid flow is calculated as electric liquid effusion meter.
It is provided with condensed water electromagnetic valve between described condensed water branch road and condensed water outlet.
Described mistake is provided with the 3rd preprocessing filter element between drainage branch road and pure water outlet.
When adopting such scheme, this water purifier power-up state, open tap water water inlet, tap water first passes around the first preprocessing filter element, passes through electric liquid effusion meter, booster pump, the second preprocessing filter element. After effusion meter senses that flow signal reaches booster pump initiation value, starting booster pump work, that carries certain flow crosses drainage to two reverse osmosis filter element, and after filtration, condensed water flows through condensed water electromagnetic valve and discharges after collecting; Pure water flows through the 3rd preprocessing filter element after collecting, flow out for user from pure water outlet. This water purifier adopts the mode that reverse osmosis membrane filter element is in parallel, with electric liquid effusion meter, booster pump is controlled, and reaches to increase hydraulic pressure, ensure the purpose of water flow. By above technology realize complete machine namely filter namely drink fresh water from pollution, it is possible to realize aquifer yield >=1000ml/min. It is a kind of water outlet safe and sanitary, reverse osmosis water purifier without water tank easy and simple to handle. The present invention had both achieved fresh water and has namely made and namely drink, and also saved water resource, was that a kind of design is ingenious, function admirable, convenient and practical water purifier.
Accompanying drawing explanation
Fig. 1 is the water handling principle figure of reverse osmosis water purifier involved in the present invention.
Detailed description of the invention
As shown in Figure 1, a kind of reverse osmosis water purifier without water tank, including first, second, 3rd preprocessing filter element 1, 12, 9, electric liquid effusion meter 2, booster pump 3, reverse osmosis filter element 4, 5, tap water water inlet 11 is sequentially connected with the first preprocessing filter element 1, electric liquid effusion meter 2, booster pump 3, second preprocessing filter element 12, reverse osmosis filter element 4 parallel with one another, 5, two reverse osmosis filter elements 4, the condensed water branch road 13 of 5 is parallel-connected to condensed water electromagnetic valve 6 and leads to condensed water outlet 7, two reverse osmosis filter elements 4, the drainage branch road 8 excessively of 5 is by leading to faucet pure water outlet 10 after the 3rd preprocessing filter element 9 filters again.
In above-described embodiment, the work process of water purifier is: as it is shown in figure 1, after complete machine is energized, booster pump 3, condensed water electromagnetic valve 6 do not work, and complete machine is holding state; Open tap water water inlet 11, electric liquid effusion meter 2 detects flow signal, when electric liquid effusion meter 2 monitor added up water reach 100��300L time, reach booster pump 3 initiation value, booster pump 3 is started working, condensed water electromagnetic valve 6 receives Flow Limit definite value or phases-time signal also begins to work, cross drainage to be filtered through the second preprocessing filter element 12, reverse osmosis filter element 4,5 in parallel, condensed water after filtration flows out from condensed water outlet 7, pure water flows out from pure water outlet 10, and now complete machine is in controlling the water circulation state; When disconnecting tap water water inlet 11, effusion meter 2 can't detect flow signal, booster pump 3 power-off, and complete machine quits work, and enters holding state. When being again turned on tap water water inlet 11, then complete machine repeats controlling the water circulation state.
