Embodiment 1）

[0028] See figure 1 , the water-saving reverse osmosis water purifier of the present embodiment comprises a flushing valve 1, a large flow throttle valve 2, a pretreatment filter element 3, a return pipe 4, a water inlet valve 5, a water diverter 6, a low pressure switch 7, a booster Pump 8, small flow throttle valve 9, reverse osmosis processor 10, high pressure switch 11, rear activated carbon filter element 12, pure water outlet faucet 13 and pressure water storage tank 14.

[0029] The inlet of the pretreatment filter element 3 is connected to the water source, and the outlet thereof is connected to the inlet of the reverse osmosis processor 10 . The booster pump 8 is arranged in the water inlet pipeline of the reverse osmosis processor 10 . One end of the return pipe 4 is connected to the concentrated water outlet of the reverse osmosis processor 10 , and the other end is connected to the water inlet line of the booster pump 8 . The large flow throttle valve 2 is arrang...

Embodiment 2）

[0040] See figure 2 , this embodiment is basically the same as Embodiment 1, the difference is that: it also includes a water purification faucet 15.

[0041] The water inlet of the clean water outlet faucet 15 is connected with the water inlet of the water inlet valve 5 . The inlet of the water inlet valve 5 communicates with the outlet of the pretreatment filter element 3 . The return pipe 4 is provided with a one-way valve 16 . The direction of the one-way valve 16 is adapted to the direction of water flow in the return pipe 4 .

Embodiment 3）

[0043] See image 3 , this embodiment is basically the same as Embodiment 1, the difference is that: it also includes a water purification faucet 15.

[0044] The water inlet of the clean water outlet faucet 15 is connected with the water inlet of the water inlet valve 5 . The pretreatment filter element 3 is provided with a solid sustained release agent 17 . The solid sustained release agent 17 includes compounds that can form complexes with calcium and magnesium ions in water after being dissolved in water. The solid sustained release agent 17 is an inorganic polymer phosphate. The pretreatment filter element 3 is composed of three stages of filter elements. One end of the return pipe 4 communicates with the water inlet or water outlet of the first-stage filter element. The booster pump 8 is arranged on the pipeline between the first-stage filter element and the second-stage filter element, or on the pipeline between the second-stage filter element and the third-stage fi...

Abstract

The invention discloses a water-saving reverse osmosis water purifier, comprising a flush valve, a large-flow throttle valve, a pretreatment filter core, a return pipe, a booster pump, a small-flow throttle valve and a reverse osmosis processor, wherein the inlet of the pretreatment filter core is communicated with a water source; the outlet of the pretreatment filter core is communicated with the inlet of the reverse osmosis processor; the booster pump is arranged inside a water inlet pipeline of the reverse osmosis processor; one end of the return pipe is communicated with a concentrated water outlet of the reverse osmosis processor; the other end of the return pipe is communicated with the water inlet pipeline of the booster pump; the large-flow throttle valve is arranged on the return pipe; the inlet of the flush valve is communicated with the concentrated water outlet of the reverse osmosis processor; the outlet is communicated with the water inlet pipeline of the booster pump; the inlet of the small-flow throttle valve is communicated with the water inlet pipeline of the reverse osmosis processor or a concentrated water discharge pipeline of the reverse osmosis processor or the return pipeline; and the outlet of the small-flow throttle valve is idle. The washing water generated when the water-saving reverse osmosis water purifier is washed can be completely recycled. Therefore, the rinse discharge water of a reverse osmosis processor can be reduced to zero.

Description

technical field [0001] The invention relates to a water-saving reverse osmosis water purifier. Background technique [0002] As we all know, the water efficiency of traditional household reverse osmosis water purifiers is very low. In fact, the water discharged as waste water includes two parts: one part is the concentrated water discharged from the throttle valve when the machine makes water, and the other part is the flushing water discharged from the flushing valve during flushing. [0003] A traditional reverse osmosis water purifier usually includes a pretreatment filter element, a booster pump, a reverse osmosis processor, a throttle valve and a flushing valve. The piping system is connected according to the following requirements: the inlet of the pretreatment filter element is connected to the water source, and the outlet connected to the inlet of the reverse osmosis processor; the booster pump is set in the water inlet pipeline of the reverse osmosis processor; the...
