Fig. 1 is a kind of current existing reverse osmosis water purifier, as shown in the figure, during its work, tap water direct taps into into the first preprocessing filter element 1 and processes, and after topping-up pump 2 superchargings, then through the second preprocessing filter element 3 and the 3rd preprocessing filter element 4, processes successively, then through reverse osmosis membrane 5, further filter, after filtration, become two-way: a road just becomes pure water after filtration through rearmounted filter core, capable of direct drinking; Another road is condensed water and is expelled to sewer line through waste water combination valve 7, and the condensed water of discharging this part accounts for 75% of the whole water yield, and in actual use, the ratio of the shared whole water yield of condensed water is higher, can cause like this huge waste of water resources.
Summary of the invention
The purpose of this utility model is to provide a kind of water-saving reverse osmosis water purifier, and excessive to solve the discharge of existing reverse osmosis water purifier condensed water and wash-down water, the problem of water resources serious waste, realizes water saving.
The technical scheme that realizes the utility model object is, a kind of water-saving reverse osmosis water purifier, comprise reverse osmosis water treatment system, described reverse osmosis water treatment system comprises water inlet, pretreatment component, reverse osmosis membrane, pure water outlet and condensed water outlet successively, in described pretreatment component, be provided with topping-up pump, it is characterized in that, reverse osmosis membrane condensed water exit end at described reverse osmosis water treatment system connects a loop apparatus, and the other end of described loop apparatus is connected to the optional position before described topping-up pump water intake end.
Above-mentioned pretreatment component comprises the first preprocessing filter element, the second preprocessing filter element and the 3rd preprocessing filter element being cascaded, described topping-up pump is arranged between described the first preprocessing filter element and the second preprocessing filter element, between the first preprocessing filter element and topping-up pump, be provided with magnetic valve, described loop apparatus one end is connected to reverse osmosis membrane condensed water exit end, and the other end is connected between described the first preprocessing filter element and magnetic valve.
In above-mentioned loop apparatus, be in series with combination flush valve.
Described combination flush valve is one and has concurrently and rinse and the magnetic valve of effluent function wherein have the two ends of the direct communicating valve of aperture of an effluent, or a general solenoid valve and a throttling valve with capillary pipe structure are formed in parallel.
The beneficial effects of the utility model are, because the concentrated water end (W.E.) of the reverse osmosis membrane at reverse osmosis water purifier increases a loop
Device, the front and back end pressure difference producing while utilizing topping-up pump operation, make the whole wash-down waters and the partial concentration water (concrete ratio is carried out difference setting according to the quality of influent quality) that in the normal use procedure of water-purifying machine, produce, be back to topping-up pump front end, with water inlet dilute mix after recycle in system, thereby greatly reduced wastewater discharge, saving water resource successful.
Accompanying drawing explanation
Fig. 1 is the structural representation of existing reverse osmosis water purifier.
Fig. 2 is the skeleton diagram of the utility model embodiment.
Fig. 3 is the structural representation of the utility model embodiment.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described further.
As Fig. 2, shown in Fig. 3, a kind of water-saving reverse osmosis water purifier, comprise reverse osmosis water treatment system, described reverse osmosis water treatment system comprises water inlet 8 successively, pretreatment component 9, reverse osmosis membrane 5, pure water outlet 10 and condensed water outlet 11, between reverse osmosis membrane 5 and pure water outlet 10, be also provided with pure water check valve 13 and rearmounted filter core 6, described pretreatment component 9 comprises the first preprocessing filter element 1 being cascaded, the second preprocessing filter element 3 and the 3rd preprocessing filter element 4, between described the first preprocessing filter element 1 and the second preprocessing filter element 3, be disposed with magnetic valve 12 and topping-up pump 2, reverse osmosis membrane condensed water at described reverse osmosis water treatment system exports a loop apparatus 16 of 11 ends connections, described loop apparatus 16 one end are connected to reverse osmosis membrane condensed water and export 11 ends, the other end is connected between described the first preprocessing filter element 1 and magnetic valve 12, certainly, this end also can be connected to the optional position before described topping-up pump 2 water intake ends, in described loop apparatus, be in series with combination flush valve 17 and recirculation water check valve 18.When reverse osmosis membrane 5 does not adopt the reverse osmosis mould of large flux, a pressure-pot 19 is set for the pure water give generating, stores supercharging described pure water check valve 13 is rear, guarantee depotition cock continuous effluent.Certainly, if the reverse osmosis mould that reverse osmosis membrane 5 is large flux, without after described pure water check valve 13, pressure-pot being set.
