Abstract

A household water purifier with zero emission relates to a household water purifier and is designed mainly to solve the problem of water resource waste caused by discharge of concentrated water from a concentrated water discharge pipe when the existing household water purifier is in use. The household water purifier comprises a three-stage front filter and an anti-osmosis device, wherein a pipeline at the water outlet end of the three-stage front filter is communicated with the anti-osmosis device through a boosting pump; the anti-osmosis device is provided with a pure water outlet pipe and a concentrated water discharge pipe; the pure water outlet pipe on the anti-osmosis device is provided with a pure water valve; the concentrated water discharge pipe on the anti-osmosis device is communicated with a household tap water pipe through a check valve; and both the household tap water pipe and the water inlet pipe of the three-stage front filter are connected with a tap water supply pipeline through a pressure reducer. The advantages of the water purifier include being capable of realizing zero emission and simple in structure.

Description

The zero release domestic water purifying machine

Technical field:

The utility model relates to a kind of domestic water purifying machine.

Background technology:

Existing domestic water purifying machine comprises three grades of fore filters and reverse osmosis unit, the water side of three grades of fore filters has pipeline to be communicated with reverse osmosis unit through topping-up pump, pure water rising pipe and concentrated water drainage water pipe are arranged on the reverse osmosis unit, during use, 1 liter of pure water of every collection just has 1.5 liters of dense water to discharge from the concentrated water drainage water pipe, causes water resource waste; If dense water is not discharged, the impurity in the reverse osmosis unit will accumulate, and reduce the osmotic effect of reverse osmosis unit, and the permeable membrane in the reverse osmosis unit also can be impaired because of hydraulic pressure increase in it, thus the work-ing life of reducing reverse osmosis unit.

Summary of the invention:

Technical problem to be solved in the utility model provides a kind of zero release domestic water purifying machine, waste water resource not during use, and also simple in structure, can prevent that hydraulic pressure increases in the reverse osmosis unit, prolong its work-ing life.

Above-mentioned purpose is achieved in that it comprises three grades of fore filters and reverse osmosis unit, the water side of three grades of fore filters has pipeline to be communicated with reverse osmosis unit through topping-up pump, pure water rising pipe and concentrated water drainage water pipe are arranged on the reverse osmosis unit, on the pure water rising pipe on the reverse osmosis unit pure water valve is arranged, it is characterized in that: the concentrated water drainage water pipe on the reverse osmosis unit is communicated with the household tap water pipe through vacuum breaker, and the water inlet water pipe of household tap water pipe and three grades of fore filters all is connected with the tap water supply pipeline through pressure reducer.

The utility model has the advantages that: because the concentrated water drainage water pipe on the reverse osmosis unit is communicated with the household tap water pipe through vacuum breaker, again owing between the water inlet water pipe of household tap water pipe and three grades of fore filters and the tap water supply pipeline pressure reducer is arranged, so dense water can enter in the household tap water pipe, can enter again in three grades of fore filters, participate in circulating filtration.The pure water of producing flows out for drinking by the pure water rising pipe, use washing in the household tap water pipe to gargle and when washing dish just with concentrated water drainage except.Therefore other water consumptions, can realize zero release always greater than drinking the water yield in real life, waste water resource not, and also simple in structure, guarantee that inclusion-free accumulates in the reverse osmosis unit, guarantee the osmotic effect of reverse osmosis unit, increase the service life.

Description of drawings:

Accompanying drawing is a structural representation of the present utility model.

Embodiment:

With reference to accompanying drawing, it comprises three grades of fore filters 1 and reverse osmosis unit 3, the water side of three grades of fore filters has pipeline to be communicated with reverse osmosis unit through topping-up pump 2, and pure water rising pipe 4 and concentrated water drainage water pipe 5 are arranged on the reverse osmosis unit, on the pure water rising pipe on the reverse osmosis unit pure water valve is arranged; Concentrated water drainage water pipe on the reverse osmosis unit is communicated with household tap water pipe 7 through vacuum breaker 6, and the water inlet water pipe 8 of household tap water pipe and three grades of fore filters all is connected with tap water supply pipeline 10 through pressure reducer 9.

Claims

1. zero release domestic water purifying machine, comprise three grades of fore filters (1) and reverse osmosis unit (3), the water side of three grades of fore filters has pipeline to be communicated with reverse osmosis unit through topping-up pump (2), pure water rising pipe (4) and concentrated water drainage water pipe (5) are arranged on the reverse osmosis unit, on the pure water rising pipe on the reverse osmosis unit pure water valve is arranged, it is characterized in that: the concentrated water drainage water pipe on the reverse osmosis unit is communicated with household tap water pipe (7) through vacuum breaker (6), and the water inlet water pipe (8) of household tap water pipe and three grades of fore filters all is connected with tap water supply pipeline (10) through pressure reducer (9).
